They continue to work tirelessly to deliver a water system that everyone can be proud of. Our responsibility goes beyond pipes, treatment works and reservoirs; it’s about ensuring the natural rivers and 860 miles of coastline continue to thrive and to make our waters the benchmark for quality. It’s also about ensuring that customers have a clean and plentiful supply of water. From apprentices to graduates, data scientists to lab technicians, environmentalists, engineers and customer service teams, everyone who works at Pennon shares the same ambition. Today we are investing more than ever to improve our assets, in new and innovative ways, both nature first and future proof, building resilience in the face of a changing climate and population growth. It’s no longer acceptable to build more concrete, or complex infrastructures, that have long term environmental impacts. From using reed beds to smart ponds and smart water butts, we want to protect the planet and use less. Our investment in Pennon Power will support our commitment to ensuring 50% of our energy needs come from renewable sources as part of our Net Zero ambitions. In 2022, the South West experienced one of the driest years on record, with reservoirs hitting their lowest ever levels as we worked to protect both river health and ensure a continuous supply of clean drinking water to our customers. We moved quickly, innovating to repurpose ex quarries and mines to store water across Devon and Cornwall. Together with this, and by You can read more on how we are engaging with our stakeholders in our Section 172(1) statement on page 128. “We’re doing this, for a water system that everyone can be proud of” Gill Rider Group Chair investing in desalination, we will continue to use innovative techniques to re-use what we have and break the cycle of drought. Whilst 2022 was one of the driest, 2023 will be known for being one of the wettest. Whilst good for water resources, this has triggered more use of storm overflows and more pollution incidents than any of us agree is right. If we could go back to the Victorian era when the UK’s infrastructure was built, we would make significant changes, and the design is the same the world over. What does set us apart from the rest of the world, is the monitoring. As one of the first water companies to achieve 100% monitoring, we will use the data and information to target our efforts to fix this. We know this will take time and we can fix this, because 30 years ago, half of our sewage in the South West did go directly untreated into the sea. In a journey starting in the 1990s with Clean Sweep, and a £13 billion investment, we created a legacy of wastewater services, and a first for the South West. The result is that we now have some of the best bathing water quality in the UK, up from c.29% in the 90s to 100% for the last three years running. Whilst excellent in between May and September, (when bathing water quality is monitored) it’s clear we need to go further, ensuring excellent water all year round. We do need to reduce the use of storm overflows. Post 2025 and as part of a wider £2.8 billion investment plan across the Greater South West, our plans will also support 2,200 jobs directly and in the supply chain. It’s a plan grounded in extensive customer research, and the Board and I met regularly with the independent Chair and deputy Chair of the Watershare+ panel who led the engagement. We also received feedback from our 90,000 customers who are shareholders through our WaterShare+ scheme. We’re pleased this plan received strong support from customers, stakeholders and our shareholders – to invest more in the region, and we believe it’s also aligned with Ofwat’s objectives. At the same time, the Board has committed to extend our zero-water poverty pledge to 2030, with a £200 million support package, as we find new ways to help our customers to save money. From our “Stop the Drop” to “Water is Precious” campaigns and innovative tariffs, we are helping customers to save water, save money and change how we all use water. That same care for customer service is being demonstrated in the growth of our non-household retail businesses Pennon Water Services and Water2Business. And with the acquisition of SES Water earlier this year, and our continued focus on the local delivery of local services, the Board are pleased to be able to enhance SES Water’s ongoing financial resilience to better deliver for customers and stakeholders and demonstrate our ongoing commitment to the UK Water Sector. Finally, I want to extend my thanks to our Board, our CEO Susan and her executive team for their support. I am grateful to have worked alongside such a talented and dedicated team over many years and I look forward tocontinuing my relationship with Pennon as a customer. Gill Rider Group Chair 20 th May 2024 4 Annual Report and Accounts 2024 « Pennon Group plc At Pennon, we all work in water because it is too important not to 150 years ago, water professionals were seen as one of the founding champions of public health. This is at our core of what we do. Today, climate change is the single biggest threat facing people and planet, water companies also need to demonstrate that we are also custodians of the environment, and as we look ahead. That’s why when asked, I always say that we all work in water because itis too important not to. Our c.4,000 employees, who live and work in the communities we support are bolstered by the wider supply chain, now collectively known as Amplify and nearly doubling the number of people we support as one of the largest private employers in the Greater South West. We are also a growing team, through our acquisition of SES Water, and we were delighted to be able to safeguard c.470 jobs. In the year, we have also signed the Armed Forces Covenant and become a disability confident employer and continue to increase our responsibility on social mobility as a tier 1 funder of the Social Mobility Partnership, launching work experience clusters, and as we look to offer 5,000 work placements for young people by 2030. I want to pay tribute to everyone who works for the Group and with us, aswecouldn’t deliver any of this without talented people doing great things for customers and each other and they are the real heroes in delivering thisset of results. Doing what’s right This has also been a year where we have refreshed our values, an opportunity to galvanise everyone who works for Pennon and our supply chain, as we grow and continue to evolve how we deliver for customers, Our fundamentals are strong As I look back on the year, the fundamentals are strong for a more sustainable future, reflected in record levels of investment, record support for customers, and as we create record numbers of jobs directly and in the supply chain, supporting the economic health of the regions we support. With a strong balance sheet and good liquidity, we retain the agility and ability to respond when it matters most and for the longer term, and in delivering on our strategy focused on UK Water. We are growing sustainably, whether through acquisition or investment, with an efficiently funded and robust balance sheet, growing shareholder value. And this in turn, is ensuring we can make good operational progress, delivering on our 4 priorities and what matters most to our customers. We are listening The UK Water sector remains firmly in the spotlight, with regulatory, political and public scrutiny at an all-time high. It’s difficult for any water company to ignore. We are listening Our customer and community roadshows have been a personal highlight for me as we have directly faced into public anger of the sector, head on and we have focused on talking about what really matters most. From Bristol to Bournemouth, and across Devon, Cornwall and the Isles of Scilly, and soon to be in Sutton and East Surrey Water, we are slowly changing perceptions, one conversation at a time. At the same time, we have embarked on our largest ever direct customer engagement, gathering the views and feedback of over 250,000 customers and 1,000 stakeholders as part of our £2.8 billion PR24 business plan submission. Our CEO’s review “The fundamentals are strong for a more sustainable future” Susan Davy Group Chief Executive Officer 5Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information This is a year in which the weather has been both our friend and our foe. With 10 named storms and 12 yellow weather warnings since September, it is a sobering statistic that 5 of the 10 wettest Februarys have been in the last 5 years, and with average rainfall increasing by 50% when compared to long term averages in the second half of the year. On one hand with more rainfall, we have been able to break the back of the drought we experienced in 2022, and in doing what we said we would by achieving 100% strategic reservoir capacity for Devon and Cornwall by April, ahead of target. This has been a monumental undertaking, from teams across South West Water and the supply chain as we have opened 2 reservoirs at Blackpool Pit this year and Hawks Tor last year, and increased treatment capacity at Rialton, alongside pump recharge schemes. We are also on track to deliver a 2-phase desalination scheme for Cornwall. It is not just been about fixing the here and now. We are investing enough now to protect resources over the next 25 years, building trust in our services for the longer term. We have delivered on our 2025 target for Devon, with 30% greater resource availability and are on track for 45% in Cornwall, with 30% delivered to date. There are always two sides to the coin, as in addition to diversifying our portfolio, it has also been about reducing demand. We are delivering on our leakage targets. And our sector-leading demand reduction schemes, are focused on supporting customers to use less water and save money, with c.500 water saving devices provided every single day last year and we are piloting trial tariff schemes to better distribute charges and encourage water efficiency. Overall, water quality continues to deliver upper quartile performance. We have delivered a step change in the Isles of Scilly, with zero failures of water treatment processes for Devon, Cornwall and Bournemouth, and with a robust action plan in place for Bristol to address the legacy issues we inherited. The significantly increased wastewater flows have also impacted our headline performance for wastewater pollutions and the use of storm overflows, with rising groundwater levels and increasing flows into the network. Historically, 70% of our pollutions have occurred in our networks. The work we have done over the last few years is working, with performance stabilising. We are achieving sector-leading internal sewer flooding performance, outperforming regulatory targets for sewer collapses and blockages and maintaining the gains we have made previously in reducing network pollutions. Turning to the 20% increase in flows we have seen in 2023; we are focused on infiltration work. We have redoubled efforts at both our treatment works and pumping stations, where the higher levels of flows have driven spikes in performance. By reinvigorating action plans, our treatment works performance has recovered from the degradation we saw last year, stabilising performance into 2024, with a combination of inlet and storm tank cleansing and risk-based generator servicing, site-based compliance, reedbed surveys and refurbishments. Efforts have now turned to the 1,250 pumping stations, with improved site MOTs, and enhanced cleansing as well as tackling power resilience. Reducing pollutions remains a top priority for the Board, and everyone who works in Wastewater. I am reassured that we have maintained serious pollution incidents at the lowest level for 2023 (2), noting we are aiming for zero. For all other incidents, we have a revised trajectory to achieving 4 star performance for the 2025 calendar year. communities and the environment. I am proud of our new values. Developed bottom up with employee engagement sessions and with our top 100 leaders and in response to our customer and stakeholder feedback as part of PR24 preparations, our values will help us to stand apart. They epitomise everything we do as a good corporate citizen, as we continue to deliver strong performance in external ESG benchmarks, retain the Fair Tax mark for the 6 th year running, move 23,000 customers on to social tariffs and welcome over 2 million visitors to our lakes and reservoirs This ensures that any customer or visitor to the region is never more than an hour away from water, and able to use them for health and recreation. We remain the only water company in the sector to reinvest outperformance directly with customers, by giving them a unique opportunity to become shareholders in their local water company with Watershare+. With over 78,000 customer shareholders, all stakeholders can be assured that customers directly benefit. As we have acquired businesses as part of our growth strategy, Watershare+ is now one of the first commitments we make. As CEO, it’s also my job to lead from the front, and champion living our values. With executive remuneration continuing to be in the media, and regulatory spotlight, I recommended to the Remuneration Committee, that the annual bonus was foregone. It’s the right thing to do. A sound business - growing sustainably We have a clear twin track organic and acquisitive growth strategy. With peak capital investment up nearly two thirds, year on year, this represents our largest ever water programme. That translates in accumulative RCV growth, of 65% and on track to 70% to 2025. This investment delivers asset backed, inflationary returns. Our operations in the Group require reliable and efficient power supply and we are investing to increase our renewable energy provision through Pennon Power, with its first EBITDA contribution due in 2024/25, supporting our Net Zero ambitions and targeting to meet 40% of energy requirements of the Group. We are also delivering on our acquisition and consolidation strategy. We are realising the benefits we set out as part of the Bristol Water acquisition, and having acquired SES Water in January, safeguarding their financial resilience through a successful equity raise, we are now fast- tracking through the CMA process, ahead of plan. Making progress on what matters most to customers, delivering on our four priorities Turning to performance, we remain resolutely focused on our 4 customer priorities across the Greater South West. We are investing to protect water quality and enhance resilience; tackling storm overflows at our beaches and eradicating pollutions across Devon and Cornwall and driving environmental gains, wherever we serve. At the same time, we have successfully managed customer bills to be lower than they were 10 years ago, and as we pledge to eradicate water poverty. Bills in the region are no longer the outliers in the sector they once were, in the aftermath of post privatisation, and the £13 billion legacy costs involved in putting waste water treatment into the region for the first time. Our CEO’s review continued Water quality and resilience Addressing affordability and delivering for customers Storm overflow and pollutions Net zero and environmental gains Our four strategic priorities £ 6 Annual Report and Accounts 2024 « Pennon Group plc “We have a robust financial position with solid financial performance and well positioned for the next regulatory period.” We are clear and transparent about where we are, and over time, we have improved self-reporting of pollutions incidents, and now are one of the best in the sector. The same higher levels of flows impacting pollutions, has made demonstrable improvements in storm overflows numbers, challenging to see at a headline number. On a like for like basis, the investments we are making today, are delivering underlying performance improvements and which we will see in future years. Of the c.280 interventions planned, they have all been completed or are underway. And we’re equally focused on a nature first approach. As we focus on improving 49 of 151 beaches through our WaterFit investment programme by 2025, WaterFit Live is giving communities and visitors to the region near real time information about their favourite beach, alongside community roadshows, as we place communities at the heart of our future plans. And whilst beaches are a priority, we are equally focused on improving river waterquality with RNAGs reduced from 19% to 12.4% and on track to get to our 2025 target. One of the benefits of taking a nature-based approach is reduced costs for customers over the longer term. With a nature first approach to investment, our award-winning catchment management programme is leading the way for biodiversity gains as well as continuing to help the way others manage their land, improve water quality, biodiversity and climate resilience. Activities range from installing water side fencing, building ponds, improving farm tracks, slurry storage, under sowing maize, as well as planting trees and buffer strips to catch and filter water. With c.127,000 cumulative hectares restored, we are also exceeding our tree planting target at over 250,000. Having worked on our catchments for the last 15 years, we have the science to back up the improvements and I was delighted that we officially opened our partnership with the University of Exeter in March 2024 providing research through a state-of-the-art laboratory into the key challenges and issues facing water, wastewater and the environment globally. In tackling affordability, it is about two things, keeping bills as low as they can be for all customers, and secondly, supporting those who are struggling. We have always been focused on being as efficient as we can be in delivering services, and in keeping bill increases to 2025 well below inflation. In fact bills for Devon and Cornwall are lower today than they were 10 years ago. That’s why we continue to support customers and communities having provided over £100 million of customer support with 132,000 customers benefiting from one or more of our affordability initiatives tariffs, building awareness of our customer outreach engagement programmes. As a result, 100% of customers in Bristol find their bills affordable and 98% across other regions. And given you can’t choose your water provider; we believe you should have asay which is why we plan to grow our unique Watershare+ scheme to one inevery 10 households and will extend this scheme to SES Water customers for the firsttime. A sustainable future in the UK Water Sector We’re reshaping the Group to be even more efficient, as we grow, and to ensure we are performance led, with planned improvements in processes and operational effectiveness which will deliver synergies. We are bolstering delivery of the wider supply chain, collectively known as Amplify, with a two-tier supplier model already in place and supporting 1,000 projects and in support of our £2.8 billion investment plan for the region and delivery of RCV growth. And to be a sustainable business, I’ve always been clear, our investments can’t just be in assets, they’re in people too. We are the only water company to have been recognised as a Top 100 employer for apprenticeships. With over 470 apprenticeships to date and accredited as a gold employer for our “earn and learn” approach, c.1 in 10 colleagues have either undertaken an apprenticeship or graduate programmes. As we promote social mobility, we are giving young people the opportunity to dive into their local water company. For the third-year running we have had our best health and safety performance, as we deliver on our HomeSafe strategy to ensure everyone who works for us and with us goes home safe every single day. We’re also leveraging technology, trialling AI in customer services and using predictive modelling to support wastewater operations. Robust Financial Position Overall, we have a robust financial position with solid financial performance and well positioned for the next regulatory period. Our efficiency programmes are focused on keeping costs below inflationary levels and despite the impacts of the unprecedented wet weather. Furthermore, with a robust balance sheet, we are also efficiently funded and growing shareholder value. Our strategy for financing will continue to seek to ensure we remain one of the most efficient in the sector, and delivered in the right way as we continue to make progress. We have raised £1.2 billion of liquidity since March 2023, and completed thesuccessful equity raise of £180 million for the SES Water acquisition. Ourwater group gearing at 63.5% is in line with policy, reflecting the increased investment spend in assets and the timing of RCV build and with a near doubling of sector-leading base returns. And the development of the B2B retailers, Pennon Water Services and Water2Business, are delivering a c.50% increase in EBITDA and increase in market share through providing excellent customer services. We have carefully considered the final dividend position for 2023/24, considering the new guidance from Ofwat in March 2024. We’ve made an assessment on the performance of the Group in the round, including the performance of the B2B retailers and the development of Pennon Power, and the overall robust performance of our water businesses. It’s in this context, we think it’s right to reflect on Ofwat’s guidance on dividends. The final Pennon dividend has therefore been adjusted to reflect the fines linked to a SWW prosecution we had in May 2023, where we were fined £2.4 million, with theultimate shareholders of the Group, bearing that impact, and not customers. The revised recommended final dividend is 30.33 pence per share. In Summary Our fundamentals are strong, reflected in record levels of investment, record support for customers, and creating record levels of jobs directly and in the supply chain, supporting the economic health of the region. We are growing sustainably, whether through acquisition or investment with an efficiently funded and robust balance sheet, growing shareholder value. The building blocks are in place, focusing on not only what we do, but how we do business. And this in turn, is ensuring we are making good operational progress, delivering on our 4 priorities and what matters most to customers. With a strong balance sheet and good liquidity, we maintain the agility to deliver on our strategy in UK Water and are well positioned for a sustainable future, with robust financials. And finally I could not end this update, without paying my personal respects to Gill Rider, our out-going Chair. She has been both a mentor and a Chair, and her championing of diversity and inclusion across Pennon is a fitting legacy on which we intend to build. On behalf of everyone who works for the Group, and will join us in the future, thank you Gill.

Policy makers Who they are We create open and transparent relationships with the widest range of policy makers, from local MPs, who seek to reflect the priorities of their constituents, to UK government who ultimately set water priorities and policy, through bodies such as the Department for Environment, Food & Rural Affairs (Defra), Natural England, and the Environment Agency. We engage with Parliamentary Committees regularly to set the tone of legislative activity, ensuring that Pennon’s voice is heard at the heart of government. But we don’t just engage with the Government, we work cross-party to ensure that Pennon’s values are heard across the political divide. In addition, and as a FTSE-listed business, we collaborate with third parties such as the CBI and Chambers of Commerce, to ensure that the voice of business in the UK isheard. Why we engage How we engage Key challenges and how we are responding Water is a precious national resource, requiring water companies and policy makers to work together to deliver the best possible outcomes for the environment, customers and communities.

These measures are part of a £125 million shareholder injection and would bring an increase in resources in Cornwall and Devon by 45% and 30% by 2025. During 2023/24 we have broken the drought cycle with our strategic reservoirs reaching 100% peak capacity in early April 2024 – a third ofthis storage was achieved through our interventions. A new supply at Gatherley was delivered in the year (adding to the Lydpumping scheme last year), reaching our 30% target for Devon. We have also achieved 30% in Cornwall with the completion of a new 22km pipeline network and raw water pump station at another redundant quarry in Mid-Cornwall, named Blackpool Pit. This new pipeline network and pump station will supply raw water straight to Cornwall’s strategic water treatment works in Lostwithiel. Theabstraction pontoon at Blackpool Pit is pictured opposite.

A number of interventions to reduce infiltration of groundwater into the sewer network have been completed in the year. These include thereplacement of the rising main on the network, the rehabilitation of31 manholes within the area and 600 million of new sewer lining. Attention now moves to ancillary works, to ensure the full spill reduction benefits are achieved. Bere Alston Bere Alston Wastewater Treatment Works The investment at Bere Alston has focused on reducing groundwater infiltration into the sewer network and removing the flow of surface water from the combined drainage and sewer network in the area. Works included the installation of 1,640 million of new sewer lining, the rehabilitation of 60 manholes, 245 dig-down repairs to pipework andthe separation of three areas of surface water from the combinedsystem. Hatherleigh New storage tank installed at our Hatherleigh site with a capacity of 120m 3 Prior to the project being completed the site had no existing storm storage. Following agreement with the Environment Agency, a below-ground storm tank with a capacity of 120m 3 was installed at the end of Q1 2023; this was a year ahead of the original regulatory deadline. As part of the programme a new inlet pumping station control kiosk andinstrumentation for the storm tank were also installed. The investment has led to a c.90% year-on-year reduction in spills incalendar year 2023, with this trend continuing into Q1 2024.

To deliver this we have announced our largest ever package of support, of over £200 million by 2030. We launched Waterfit Live ahead of the 2023 bathing season, to give customers more information about the impact of our wastewater network on their local beach. Our interactive beach maps provide a live view to see if a storm overflow is in operation at their local beach and the potential for it to be temporarily affecting bathing water quality. Alongside the map, we have also shared information about the bathing water quality at that beach, the improvement over time, and the work we are undertaking to further enhance water quality at our bathing waters through our WaterFit programme. Our community engagement programme has responded to interest around the near-real-time information we have been sharing on storm overflows, by holding both online and face-to-face events with local communities such as Exmouth, Harlyn Bay and Lyme Regis. As well as giving customers the opportunity to challenge us, these roadshows have allowed us to explain our short- and long-term plans, provide data on sampling in their local area and explain how we manage the impact of new developments on our network. We also gathered feedback from local communities that will help shape investment priorities and the way in which we continue to engage with them in the future. This includes: • Proactive auto-enrolment of customers onto tariffs to remove them from water poverty. • Affordability toolkits to give customers flexibility in how they receivesupport. • Taking a water-efficiency-first approach. • Working with partners to ensure we engage with and supportcustomers. Using this tool, we have already identified those in water poverty and begun to auto-enrol these customers onto support tariffs. In the South West Water area, we auto-enrolled 8,000 customers onto our WaterCare tariff in 2022/23 and a further 18,000 in 2024/25; with more customers set to benefit into 2025 and beyond. Our approach to helping those in water poverty is supported by our affordability toolkit. This provides a range of options to help customers lower their water bill, including switching to a metered tariff, payment breaks, water efficiency advice and home visits, low tariffs and help with managing debt. 15Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Net zero and environmental gains - Pennon Power, Fife In April 2023, Pennon Power acquired its first renewable energy site fordevelopment in Dunfermline, Fife. The site comprises a 45MWp solar farm, with a 30MW 2-hour co-located battery storage system, situated on the site of a former open-cast coal mine. The annual generation from this single asset will be equivalent to the entire current Group renewable energy portfolio. Since acquisition, a series of activities have been completed to prepare the site for construction including design specification, geotechnical investigations, grid connection designs, planning condition discharge and identifying an EPC contractor to build the site. Construction contracts were signed in early 2024, and the site is currently working towards commissioning of the solar array in late 2024, with the battery storage unit connecting in Q1 2025. Groundworks pull-out testing conducted in preparation of construction of the solar array. How we are preparing for the future We are not just focused on meeting the immediate challenges we face. CREWW, is a 25-year research partnership between South West Water and the University of Exeter (UoE). It builds on many years of collaboration between the two organisations including our catchment management programme, Upstream Thinking (first pioneered in 2006) which has acted as a beacon of change which others in the water sector have followed. CREWW is bringing together subject matter experts from SWW and UoE, under one roof, who will combine their knowledge and expertise to undertake innovative research into some of the most pressing challenges facing both the business and the water industry. The outcomes will help inform our operations and enable us to better deliver for our customers, the region and the environment. Officially opened in March 2024, the new dedicated, operationally net zero research facility is underpinned by a £21 million capital and research investment by South West Water. It is the only water sector partnership to receive support from the UK Research Partnership Investment Fund (UKRPIF), as well as being the largest RPIF-sponsored project in the SouthWest. CREWW has already begun working on projects including the creation of a state-of-the-art laboratory which will tackle the scourge of microplastics in our environment. The project represents an investment of £1.4 million from South West Water and will initially develop our understanding of the presence of microplastics in sewage sludge to inform our wastewater operations. In the long-term, the ambition is to provide guidance and support to any stakeholders involved in sewage operations, their management or monitoring, as well as regulators. The project team at CREWW is headed up by Professor Tamara Galloway, an internationally renowned scientist in the field of microplastics. Tamara and her team work alongside wastewater experts from South West Water, including Helen Dobby, the company’s Headof Environmental Performance.

Since then, £200 billion has been invested, catching up the previous decades of under-investment, improving services and protecting the environment. Every day, homes and businesses receive a continuous supply of world-class water – ranked consistently as among the best in the world. Household and non-household consumers have seen significant improvements to customer service. And with the installation and upgrade of vital infrastructure across communities, environmental standards are higher than they have ever been, with improvements to the quality of rivers, lakes and coastal waters. This is particularly so in the regions we serve. When South West Water was privatised, nearly half of all sewage in the region was untreated and discharged directly into the sea. Testing carried out to assess levels of harmful bacteria showed bathing water quality was low, with only 28% passing the most stringent tests. We invested, including through our Clean Sweep programme, to ensure that world class wastewater services were put in place for the first time – so that all sewage is now treated through one of our 655 treatment works. Privatisation was set alongside the establishment of independent regulators, which has provided powerful incentives to the industry to innovate and transform in order to drive efficiency, deliver against the obligations, and ensure a stable operating environment for investors. Greater innovation and efficiencies have been delivered alongside record investment – due to the sector’s stable regulation, which has long attracted investors. Investors are essential to the sector, providing investment that has supported record levels of investment whilst keeping bills affordable, with bills remaining at around £1 a day. Without this investment, all water companies would collect all expenditure requirements through customer billson a ‘pay as you go’ basis – which would make bills much more volatile and higher than they are today. Consolidation and mergers across the sector over the last 30 years have provided benefits to customers, setting new benchmarks for the sector. Today, there are 16 privately owned water companies – of which 11 provide water and wastewater services and five provide water only services. Collectively these provide clean water through a mains network that is 340,000km long, and wastewater services through 567,000km of sewers and6,000 wastewater treatment plants. Pennon is one of the three FTSE-listed companies that supply water and wastewater services across England and Wales. Pennon’s group ofcompanies provides water and wastewater services to a population ofc.4.24 million across the South of England. The non-household retail market The non-household retail market allows up to 1.2 million businesses and other non-household customers across the country to choose which retailer they buy water and wastewater services from. The non-household market operates through a controlled portal operated by Market Operator Services Limited. This has required the separation ofthewholesale and retail arms of water businesses. Pennon Water Services was established to manage the non-household retailbusiness for Pennon via a retail venture with South Staffordshire plc. Our reach into non-household has grown from the addition of Water2Business and SES Business Water to the group. The power market Pennon Power is a start-up business, wholly owned by Pennon Group to generate clean energy. The energy market is regulated by the independent energy regulator, Ofgem. To date Pennon Power has acquired four projects in the UK and each site has a capacity less than 50MW which is considered to be small-scale solar development for planning purposes, this means planning permission was granted by the relevant local planning authorities. Each of the projects has attained planning consent and Pennon Power will construct them. Once operational the projects will generate enough electricity each year to power c.50,000 homes. Pennon Power was established to support delivery of the Group’s Net Zero commitments and to provide financial protection from energy price volatility whilst providing sustainability financial returns and to contribute towards Group profitability. 17Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Water companies have a vital role in society, operating in the public interest to ensure safe and reliable water and wastewater services for all. As a provider of water and wastewater services, we are subject to regulation on price and performance by economic, quality and environmental regulators. Thisregulatory framework is designed to safeguard the best interests of customers and the environment. Defra sets the overall water and sewerage policy framework in England, while our regulators focus on specific aspects including water and sewerage policy, economic, environmental, drinking water quality and the customers we serve. The water sector regulatory framework Our regulators Department for Environment, Food and Rural Affairs (Defra) Defra sets the overall policy framework in England, including the environmental and service requirements. Climate change, growth, consumer expectations, and macroeconomic trends all impact on the policies that Defra sets. Ofwat Ofwat is the economic regulator, with duties to protect the interests of consumers, and ensure companies can carry out their functions, and ensure companies can finance their functions – through promoting efficiency, innovation, competition and economic growth. Environment Agency (EA) The EA is the environmental regulator focused on protecting and improving the environment. It is also responsible for managing and reducing flood risk. The EA is a principal advisor to Defra on the water environment. Drinking Water Inspectorate (DWI) The DWI is the drinking water quality regulator, with responsibility for ensuring that companies supply wholesome water that is clean and safe to drink. Consumer Council for Water (CCW) CCW represents the needs of customers, and supports customers who have complaints about their water company. Natural England Natural England is the government’s advisor on the natural environment, with the aim to protect and improve the natural environment. Market Operator Services Limited (MOSL) The non-household retail market allows up to 1.2 million businesses and other non-household customers across the country to choose which retailer they buy water and wastewater services from. MOSL manages the day-to-day running of the non-household retail market, ensuring that wholesalers and suppliers who trade in the competitive market work together effectively. Our regulatory positioning What we do now is crucial in terms of delivering plans now and planning forthe future. And, as we operate at the forefront of the changing regulatory water markets, we remain well placed to respond to change and to identify further growth opportunities. Our strategy is to be a responsible leader for the regions we serve today and every day. Our vision is to create collaboration opportunities and drive transformational changes through innovation across the value chain of the water sector. We are focused on demonstrating leadership within the water sector. Attheheart of this is how we manage water and the water cycle. We are pioneering new technologies and methods to improve customer service, efficiency and resilience while working closely with industry peers, as appropriate, and with our supply chain, to identify and implement best working practices across all areas of the business: • We are continuing to upgrade and modernise our networks and assets toaddress climate change and accommodate a growing population. • We are leveraging digital technology to better monitor and understand factors that impact water quality and availability, enhancing our ability totrack and understand consumption to support customer engagement and affordability, optimising performance, and to understand and prioritise the innovations in water quality management. • We are learning more about the use of nature-based solutions which restore or imitate natural processes – such as improving water storage by creating smart ponds or restoring peatlands. We see these as mainstream, scalable options for water management. • We are exploring opportunities to build water resilience through non- climate-dependent water sources, such as repurposing quarries and wastewater treatment and reuse – with only a fraction of wastewater currently reused this is important area for future development. With the opportunities that we see, we welcome the development of market mechanisms within the sector to drive innovation and value for customers, the environment and stakeholders. 18 Annual Report and Accounts 2024 « Pennon Group plc Our Future Plans: 2025 to 2030 The five-yearly business planning cycle Every five years, we submit our future plans to the economic regulator, Ofwat. Our business plans set out our investment proposals, performance improvements and targets, the benefits of our plans for customers and communities, and the impacts on customer bills. In October 2023 all 16 regional companies submitted their business plans to Ofwat as part of the 2024 Periodic review of prices (PR24), covering the period 2025-30 (AMP8). This saw an unprecedented £96 billion of investment planned for AMP8 – a near-doubling of the £51 billion of AMP7. Our plan for the South West In October 2023 we shared our Plan for Change 2025-2030. Our PR24 Business Plan represents a step-change in our long-term strategic approach. It includes a clear outline for all stakeholders of our purpose and strategic ambition, and our priorities for the next 25 years and five year focus. This has reinforced how we will prioritise, plan and manage for the future and ensure that we are focused on things that matter the most to people, communities and the local economies where we operate. Our plan 2025-2030 is a no surprises plan, as we continue to do what we said we would. It’s a plan that goes further in tackling the biggest challenges in our region, as we invest to protect water quality and enhance resilience, tackle storm overflows at our beaches, eradicate pollutions and protect theenvironment from climate change. Our £2.8 billion investment will create c.2,000 jobs in the region, as we commit to providing 1,000 apprentices and graduate opportunities to 2030. It will provide much needed job security in the wider supply chain across theregion. It’s also a balanced plan, between water and wastewater, and one we are well placed to deliver. To further bolster our best-in-class approach toaccountability, we are developing our new Environmental Advisory Panel to hold us to the same high standards as our WaterShare+ Customer Advisory Panel protecting customer interests. Overall this plan has received strong support that we should invest more, with universal agreement that the priorities are the right ones. We therefore consider that it meets Ofwat’s quality and ambition assessments, with an outcome framework anchored in customers’ expectation and aligned with Ofwat’s objectives for PR24. In summary, our 2025-2030 business plan is a plan building on the momentum we have today, and which goes further in tackling the biggest challenges in our region, as we invest to protect water quality and resilience, tackle storm overflows at our beaches, eradicate pollutions and protect the environment from climate change. With a laser like focus on efficiency, it is also a plan that supports customer affordability. Our £2.8 billion investment isan ambitious plan, the right plan, and the right deal for our region. The next steps in PR24 In October 2023 all companies submitted their business plans to Ofwat following 18 months of analysis and engagement.

These interactions have led to the creation of our four strategic priorities. 20 Annual Report and Accounts 2024 « Pennon Group plc Each and every day we operate a water recycling system for the region. Over 30 years we have invested more than £13 billion in the areas we serve, innovating to deliver world-class drinking water, cleaner, safer bathing beaches and more reliable services. We have also supported nature to thrive and pioneered ways to give our customers a say in our business and a share in our success – all for a little over £1 a day. Our Strategic Direction to 2050 sets out our ambition for this water system for the next 25 years. It sets out the leadership and action we will take, the action needed from others, and the opportunities we must collectively grasp if we are to ensure high-quality, reliable and resilient water services for future generations. Significant challenges lie ahead and some are very real today. Between now and 2050 we are striving to provide the services society needs, expects and values. Over the next 25 years we will invest to address storm overflows into beaches and rivers, minimise nutrients in rivers, innovate to remove plastics from sludge and maximise the beneficial use of sludge, achieve net zero, data transparency, decommission lead pipes, protect supplies from emerging contaminants, achieve world class leakage levels, build drought resilience, ensure affordable bills for all and do our bit to address the environmental crisis. We are truly on a journey to a water and wastewater system that we can all be proud of. Sequencing and balancing this investment is a great challenge, and we have long term adaptive plans to make sure that we tackle the biggest challenges and deliver the greatest outcomes first. Our Ambitions to 2050 As a responsible business we have set out our Strategic Direction to 2050, driven by our purpose, to support the lives of people and the places they love for generations to come. Our aims and outcomes by 2050: • Resilient infrastructure systems – able to withstand the impacts of changing and more extreme weather patterns and meet environmentalstandards. • Incentives to innovate – innovation in frontier technologies to drive efficiency, and to enhance mitigation and adaptation to change. • Working with nature – to manage flows in a different way, generatingsocio-economic benefits and biodiversity, – rather than pouring concrete. • Improved water efficiency – conservation is essential for economic andenvironmental sustainability. Working with others to address water use across households and industry: agriculture to manufacturing. • Growth and support for local economies – water is an economic driver that can facilitate growth and development, supporting agriculture, tourism, manufacturing, energy and mining. • Support for the circular economy – maximising the beneficial use of waste and ending the use of high grade drinking-quality water to water gardens and clean driveways – through more local storage and recycling of rainwater. • Building talent – ensuring our pool of talented, diverse people. • Working with stakeholders – to together deliver transformational change. The water cycle is a common good, a finite resource, and crucial segment of our economy, that needs to be protected through multi- stakeholder approaches to partnerships and investment. • Protect vulnerable customers – maintaining our pledge to end water poverty by 2025.

We pride ourselves on doing the right thing. The quality of the services that we provide is of critical importance to our business, however we place equal weight on how we deliver those services through strong financial governance, a focus on the environment and investment in our people – in effect our ESG DNA. In this section, we reflect of how we have, this year, brought this approach to life. Firstly, we focus on our approach to ensuring that we are financially sustainable, both from a balance sheet point of view and in relation to our ESG responsibilities; next we focus on our environmental delivery strategy which is central to everything we do; then we look at how we invest in our 4,000 colleagues to ensure they are valued and safe in turn delivering excellent customer service and driving growth and opportunity in the regionswe serve. Strong and ethical financial governance We continue to maintain financial resilience underpinned by an ethical approach, as evidenced by retaining our Fair Tax Mark accreditation and adherence to our sustainable financing framework. Financial resilience Our current gearing is at a relatively low level compared to the sector, and as we move into the next regulatory period our gearing will benefit from regulatory true-up adjustments, taking our opening Regulatory Capital Value (RCV) to c.£5.4 billion excluding SES Water. Through 2025 to 2030 we anticipate nominal RCV growth of 38% (real – 25%) reflecting our long-term investments and the value being created for customers, the environment and our investors of which two thirds are pension savings, and charities, as well as employees and customers. Having considered Ofwat’s cost of capital and retail net margins, we have prepared our plan on that basis. We plan to continue to finance activities in away that will maintain key financial ratios, consistent with a strong investment grade rating. We will take a balanced approach to the sharing How we deliver Fair Tax Mark We are proud to have been awarded the Fair Tax Mark for the sixth year in a row in December 2023. The Fair Tax Mark accreditation scheme is the gold standard of responsible tax conduct. It seeks to encourage and recognise organisations that pay the right amount of corporation tax at the right time and in the right place. Accredited businesses include listed companies, co-operatives, social enterprises and large private businesses. As a FTSE 250 UK-focused company, Pennon takes its responsibility to transparency and societal contribution seriously which includes ensuring it pays the right amount of tax, in the right way, at the right time. The Group became the first UK business in the water industry to be awarded the Fair Tax Mark in 2018 and has now successfully retained it each year since. How we deliver value For investors and the Group We focus on our approach to ensuring that we are financially sustainable, both from a balance sheet point of view and in relation to our ESG responsibilities.

Advance planning for the transition to the plan’s delivery model has been underway since September 2022, broadening our supply chain alliance, withpartners already in place and delivering our current plans. We have considered how else to rebuild trust with our actions. We have demonstrated restraint in our approach to executive pay and our dividend policy ensures we take a holistic view of performance including outcomes forboth customers and the environment. Sustainable Financing Framework Created in 2018 and updated in 2021, Pennon Group’s Sustainable Financing Framework, in alignment with the ICMA Green Bond Principles (GBP), Social Bond Principles (SBP) and the LMA Green Loan Principles (GLP) and Sustainability linked loan principles (SLL). Under the Framework, Pennon Group can issue securities as well as enter into financing relationships to support investment across the Group’s activities. The Group aims to raise allnew debt through the framework and in FY23/24 the proportion achieved was c.80%. Investing in our environment The environment and nature first solutions underpin three of our four strategic priorities set out in our K8 Business Plan evidencing our commitment to improving our communities and in turn the lives of our customers. We have delivered against this commitment in a multitude ofways as set out below. Collaborating for nature recovery Pennon is engaged and participating in a range of local and regional public, private and third sector partnerships tacking action to tackle climate change and nature recovery, including the local nature partnerships and catchment partnerships. We also convene forums and events, including our Let’s Talk Water stakeholder forum, to engage partners and share best practice, reflecting together on progress and developing shared plans for the future. We are proud of the delivery partnerships with whom we monitor, collaborate and deliver ourenvironmental improvement and biodiversity enhancement activities. Biodiversity enhancement Catchment management protects and improves river quality and critical water abstraction sources to provide clean, safe drinking water, reducing the need for treatment. It is supported by our customers as part of Pennon’s commitment to protect and enhance the environment in the drinking water catchments in which we operate. This performance commitment is designed to incentivise an increase in the area of land under active improved catchment management as part of the ‘Upstream Thinking’ and the more recent ‘Green Recovery’ project interventions. The annual target for Upstream Thinking is 10,000 hectares of new land under active improved catchment management (50,000 more hectares over the five-year regulatory period). The Green Recovery programme will deliver a further 10,000 hectares of new land under active management during the four years it will be active leading up to 2025. In 2023/24 a further 11,854 hectares of land were added to our Upstream Thinking project whilst a further 3,364 hectares were added to the Green Recovery programme, resulting in an annual delivery of 15,218 hectares against an annual combined target of 13,000 hectares. This brings our cumulative position to 126,733 hectares ofnew areas under active catchment management since April 2015, well overthe target for this plan period of 123,209 hectares. Biodiversity compliance In order for Pennon to avoid pollution harming the most special and rare habitats and species present across the South West, we have a particular focus on freshwater locations. This includes sites which are designated as a Site of Special Scientific Interest, as a Special Area of Conservation, as a Special Protected Area, or as a County Wildlife Site. During 2023/24, there were no pollutions events at any of these locations and therefore, as in the previous three years, the target was met. This outcome supports the Pennon commitment to achieving the outcomes of the Government Environmental Improvement plan and its ambitions to improve the condition of all Sites ofSpecial Scientific Interest in the next ten years. Preventing biodiversity deterioration The maritime nature, climate and geography of the South West means that wildlife and nature are particularly under threat of deterioration from the presence and spread of invasive non-native species (INNS). INNS can impact on all aspects of the business with significant operational, compliance, reputational and financial risks and are considered to be one of the most significant causes of biodiversity loss globally. We have delivered biosecurity installations at Pennon sites, to prevent the introduction of new and spread of existing INNS and over the last year we have accelerated our delivery of guidance and awareness raising signage which are now installed at 121 sites. We have also installed biosecurity wash down facilities and are scoping two further watercraft washdowns. Our exemplar biosecurity wash down facilities at Roadford, includes a pressure washer for watercraft, an angling dip tank and a boot scrub. Putting non-native trees to good use to help restore damaged peatlands The Natural Resources Team have removed non-native trees from two wastewater treatment sites to remove large conifer trees as part of biodiversity improvements. The trees that have been removed have been replaced with native broadleaf species such as oak, hazel, lime and rowan that offer much greater benefits to birds and other species. The logs from the cut conifer trees have been recycled for use in peatland restoration work at two South West Water sites – Burrator Reservoir in Devon and Park Pit in Cornwall. This work is being carried out by the South West Peatland Partnership, a £13 million project, led by South West Water, which isdelivering peatland restoration in the South West of England. The wood removed from the sites has been used by the South West Peatland Partnership to create leaky wooden dams, or timber rounds, which help to trap water in the environment, restoring dried and degraded peat bogs. The work will ultimately help to prevent run-off from the land into the watercourse, improving water quality in the area and trapping carbon in the landscape. Our business model continued Beach clean at Portwinkle - Sept 2023 24 Annual Report and Accounts 2024 « Pennon Group plc Investing in our People As one of the largest employers in the region, with almost 4,000 colleagues, we have a responsibility and duty to make a positive societal contribution. Our goal is to be the Employer of Choice across our region through promoting social mobility, prioritising Diversity and Inclusion by addressing racial and gender inequality. We provide safe, secure and meaningful employment where all employees are paid fairly for the work they do and where trust is high. We want to show that it is a dynamic and exciting time tobe working in the water industry. Over the past 10 years our region has seen significant population growth. It’s been estimated that more people moved to the South West during and following the pandemic than had been anticipated by 2050. This increase in population has an impact on many different areas of society, including employment, housing and opportunities for young people. With a double coastline and dispersed population, many coastal towns around the South West suffer from high rates of poverty, unemployment and health risk factors, together with poor housing and public service provision, poor public transport and communication connections. All this goes to show that whilst the greater South West region has traditionally had a reputation as a well-off area, in reality the picture is far more complex. This places an even greater responsibility on Pennon, as the largest private sector employer in the region, and given the wider supply chain we support. Our Reward Strategy continues to evolve each year, noting the feedback we receive from colleagues ensuring it aligns to our People Strategy and our new Group Values. The key focus for this year has been on supporting colleagues during the cost-of-living crisis. Prioritising those colleagues that need it most and bringing forward the employee bonus payments to help those in most need. At Pennon we take our social stewardship role seriously, whether that’s through driving our environmental improvements or growing the number of jobs we support. Our exciting business plan, submitted to our regulators this year, targets the creation of 2,000 new jobs as part of a wider £2.8 billion investment planned across the Greater South West – a doubling of investment from the first half of this decade. Our business plan fosters our new Values and aims to have a positive impact on customers, communities, colleagues and the environment. Our approach to Human Capital seeks to go further: supporting Community Investment and social mobility across the Greater South West by creating education and employment opportunities across our region; ensuring we pay our employees a fair wage for doing a fair day’s work and therefore be well placed to be able to make a wider societal contribution; and delivering our Diversity and Inclusion strategy by prioritising diversity of thought, gender and ethnicity to promote social mobility and opportunity for all. This is all part of a wider strategy to be the employer of choice in the region, and in creating a Great Place to Work. Colleagues from our Laboratory team at Countess Wear, Exeter Our new Group Values Pennon Group has evolved in recent years, with the sale of Viridor in 2020, the acquisitions of Bristol Water and SES Water, and the formation of new divisions including Pennon Power. These changes created an opportunity to evaluate and refresh our corporate values that had been in place for some years, resulting in a new set of values that more properly reflect who the Group is today and represent ourpeople at their best. Corporate values are guiding concepts that shape our culture, behaviour, and decision-making processes. They help colleagues match their actions and behaviours with the company’s overarching mission and objectives, giving a framework for how colleagues should engage with one another, with customers, and with other stakeholders. This will help strengthen Pennon’s collective values, offer everyone with a set of authentic and emotive guiding principles, provide clear direction for supporting behaviours, and distinguish us from the rest of the industry. It was critical to develop a set of values that not only reflect today’s business and teams, but are also more than just words on a poster. Weintended to develop a set of values that are distinctively Pennon, are interwoven into daily actions, and are consistently demonstrated byour teams across the Group. Our new values were developed after intensive involvement and listening sessions with the Pennon Executive Board, the larger leadership group, colleague representative groups such as the employee forum, and comprehensive colleague listening groups. Our values also incorporate the views of our customers collated during our biggest ever customer listening exercise conducted during PR24. Our new values acknowledge a significant shift in how we seek to deliver our strategic priorities across the Group and are intended to serve as a unifying thread across all areas of the Group. The goal is to distinguish ourselves from all other water firms and environmental infrastructure businesses. The new values will differentiate how we carry out our plans. The new values are: Be you We want you to bring your best every day. Be open and inclusive, work together and win as one team. Let your passion inspire those around you. Be authentic, make your mark and be you. Be rock solid We want you to be the one we all look up to. Be trusted. Act with integrity and make good on your promises. Build trust, one relationship at a time. Be rock solid. Be the Be the future We encourage you to be curious and challenge convention. Share ideas with confidence and purpose, and help share our future. Embrace change. Drive progress. Own the challenge. Bethe future. 25Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Speak Up Our Speak Up whistleblowing policy continued to operate throughout the year, providing another engagement channel. Speak Up helps to create an open, transparent and safe working environment, where employees feel able to speak up and are supported if they do so. Read more on Speak Up on page 143 in the Corporate Governance report. Additionally, all employees are invited to pose questions or comments to our senior leaders through our new ‘open door’ communication channels. This new approach brings together several employee communication channels and encourages employees and senior leaders to keep connecting more. Enhancing our employee communications Each year, we review and seek to enhance our employee communications and engagement channels. Our regular Big Chat video calls with our CEO and the executive team continue to be very well supported by employees, with strong engagement. Items discussed largely focus on the topical business issues of the time plus key employee highlights. We have also broadened the group of speakers, involving colleagues from all areas and levels across the company. Our Time to Talk sessions focus on a broad range of topics and are supported by many external specialist speakers and facilitators. Topics discussed include mental health, the cost-of-living crisis, financial wellbeing, apprenticeships and business-specific initiatives including nature and catchment management. Our internal communications tool and discussion platform, Viva Engage, is growing in popularity and is now used regularly by over 2,000 Group employees. For our remote teams working tirelessly around the clock, we host regular breakfast meetings supported by our senior leaders. These have proved to be helpful in promoting more effective two-way communication with front- line operational teams. WaterWorks is the name given to the monthly performance measures dashboard, which helps employees keep updated on how we are delivering for our customers, communities and the environment. It’s important that all our employees are regularly updated on these critical measures regardless of which part of the Group they work for. Talent development We have a strong commitment to investing in the development of our employees and in building and recognising talent across the Group. Training and development are available for employees at all levels within the Group and all are actively encouraged to participate. Our aim is to increase productivity, job satisfaction and safety, and to equip the next generation of leaders and employees with appropriate knowledge, skills and the competencies they need to thrive. Our business model continued Launch of our Reciprocal Mentoring Programme - Dec 2023 Immersing the organisation A complete Values launch programme has been established to ensure that the values are followed as guiding principles by all colleagues. This began inJanuary 2024 and will continue through 2025. To properly embed the values, we need behavioural change accompanied by a new structure for recruitment, induction, performance management, and reward. Setting the tone from the top is also important in ensuring that these principles are reflected across the company and the Group. To ensure a successful launch and embedding of the new values, as well as to accelerate our cultural transformation, the strategy includes the development of a behavioural framework and training, both in workshop format for leaders and e-learning for all colleagues. This supporting training component will ensure that all colleagues understand what the values mean and how their actions at work affect performance. Senior executives will participate in face-to-face workshops as part of a series of leadership sessions held throughout the year. An internal communication campaign will also continue for several months through all business areas, informing colleagues about what each of the values implies, how they can bring these to life, and where they will see the values interwoven into daily company operations. Across the Group we have developed a coherent approach to leadership, culture, talent, and skills development which will not only help us unlock the full potential in our business, ensuring we are match fit today, but also in anticipation of future challenges. Ensuring our people are at the heart of all these key areas of focus will mean we continue to successfully deliver for all our customers and stakeholders that rely on us. Our people are our greatest asset. We are proud of the values we live by in all that we do and we have been delighted in how our employees have risen to the challenges we have faced throughout the last year and in going above and beyond to deliver for our business and our customers. We continue to work to develop strong relationships with our employees and Trade Union Partners, ensuring we are engaging with these important stakeholders in our business in all aspects of our People Strategy. As a purpose-led organisation, Pennon has strong values and ethics which are important barometers in fostering the culture and beliefs that we require to be successful. One of the key reasons why we use Great Place to Work to survey our employees is that it is one of the few providers that seeks to measure values and ethics. These are notoriously difficult areas to measure as they are impacted by individual’s personal values and ethics. See page 119 on how the Board monitors culture. Great place to work To enhance our Great Place To Work (GPTW) Colleague Survey, we have introduced pulse surveys during the year to give colleagues additional opportunities to provide structured feedback during the year. The pulse surveys provide a regular stream of feedback in additional to the full survey which we conduct annually. We are delighted to be recognised as a Great Place To Work and continue to work hard to keep engaging and supporting our employees to enable them to be able to bring their best to work and to ensure we are creating the best work environment and supporting themappropriately. Listening and acting on employees’ views Under the Financial Reporting Council’s (FRC) code of standards, companies are required to explain how they are incorporating employee views in Board decisions. You can read more on how the Board is engaging and making decisions in our Section 172(1) statement on pages 128 and 129. 26 Annual Report and Accounts 2024 « Pennon Group plc26 Annual Report and Accounts 2024 « Pennon Group plc As a business we joined the 5% Club, an organisation with over 1,000 members that aims to address the issue of poverty arising from high youth unemployment and a shortage of the right skills for the workplace of today and tomorrow. For the second year running, we were delighted to be awarded Gold Membership status of the 5% Club as we have around 10% of our employees undertaking apprenticeships or on a formal structured graduate programme. We are the only utility sector company to achieve the Gold Membership accolade and have done so for two years. Achieving Gold status demonstrates our long-term commitment to investing in structured apprenticeship and graduate programmes for our employees. Apprenticeships We are delighted that one of our apprentices, Meg Ginsberg, was awarded a Special Recognition Award at the National Apprenticeship Awards for being an outstanding apprentice and ambassador. Meg is a Project Management Apprentice in our Engineering Department. Despite being a wheelchair user, nothing holds Meg back and she thrives in this role, leading by example and promoting apprenticeship and women in engineering at every opportunity. We have a long-standing commitment to apprenticeships. After doubling our commitment and target for apprenticeships where we now pledge to support 1,000 roles by 2030, we are delighted to report we are ahead of schedule and have welcomed 470 since 2020. Attracting and developing thenext generation of talented employees is vital in building resilience in our workforce and ensuring we can deliver the essential services our customers and communities deserve. Our graduate programme After launching our new graduate programme in 2021 and setting a long-term commitment to recruit 100 graduates, we have doubled this commitment to now support 200 new graduates on a structured two-year development programme by 2030. Since the launch, the graduate programme has recruited 85 talented graduates, with 55% being female and over half being ethnically diverse or international graduates. Attracting larger numbers of female and ethnically diverse employees has been a core part of our People Strategy. We are delighted our graduate programme is helping deliver this outcome whilst providing high-quality career opportunities for all these individuals. Leadership development We continue to invest in our leaders and, utilising our ‘Best of the Best’ mindset following our integration with Bristol Water, we have rolled out two leadership programmes across the business, LEAD Aspire and LEAD Programme. LEAD Aspire is a four-day programme for employees who have been recognised as being a leader of the future and are working towards this as part of their personal development plan. The programme allows them to develop their leadership mindsets and approaches, explore leadership theories, models and best practices, and learning that you don’t need a title to be a leader. The four-day programme also has senior leaders from across the business sharing their thoughts on leadership, providing great insight into their personal experiences of leadership and how it has shaped them. Our LEAD Programme is for our current manager and leadership population to help them hone their leadership skills, working across a six-month programme on leadership mindset, such as personal impact and purpose- led leadership and skills areas such as coaching and mentoring, inclusive leadership, and building high-performing teams. Throughout 2023/24, we delivered 20,000 training days, ensuring that onaverage each employee received 50 hours of training – 7 days. Prioritising health and wellbeing Our wellbeing strategy is a core area in our People Strategy to ensure our people know that we care about them. It is estimated that in any given week, one in six people of working age experiences a common mental health problem like stress, depression or anxiety. Most of us will understand, from personal experiences or friends and family, the huge personal cost that this can bring. Separately, data from Champion Health, our online wellbeing platform provider, supports the outcomes from the Great Place to Work survey. 93% of employees who completed the health assessment were motivated to change, with their three key areas being improving energy levels, reducing stress and improving mental wellbeing. Our wellbeing strategy focuses on the following four main areas: Mental Taking care of our minds, coping effectively with life and creating satisfying relationships. Physical Taking care of our bodies, acknowledging the importance of activity, nutrition and sleep. Financial Taking care of our financial wellbeing, being in control over ourfinancial future. Community Encompassing the major external and internal factors such associal health. Our approach to wellbeing, incorporates a number of initiatives including: • Mental Health First Aiders: We have trained over 100 Mental Health First Aiders across the Group – one for every 40 employees, ahead of our target of one for every 50 employees. • Wellbeing Champions: We have established a network of wellbeing champions across the business to help us engage colleagues. • Time To Talk: Regular sessions where colleagues are invited to join online webinars focusing on a range of health and wellbeing issues, primarily mental health. • Champion Health: Our Champion Health portal gives colleagues a broad range of resources, advice and guidance across all areas of wellbeing, from healthy recipes to fitness regimes, mental health support and health assessments. It is free to both employees and their families. • FinWell partnership: We have launched a new partnership with FinWell, a financial wellness organisation, to provide employees with help, support and advice about their personal finances. • Inside Out partnership: Our close partnership with the Inside Out Leaderboard provides a tangible way of demonstrating leadership, commitment and action to the mental health agenda. • EAP Helpline: Our Employee Assistance Programme (EAP) had a 6% uptake compared to the industry average of 1.39%. The service is also available for employees’ families. Our 2023 cohort of graduates 27Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information HomeSafe Bite-size Live event - July 2023 HomeSafe, the Group’s flagship health and safety programme HomeSafe has targeted three specific areas this year, building on the foundations delivered last year to drive continued improvements in all health and safety activities. This focus has seen the Group’s Lost Time Injury Frequency Rate (employees and agency, excluding contractors) almost halve in the year, and furthermore seen a 75% reduction in actual lost working days, delivering an additional 450 productive days back into the business. The three areas we focused on: 1. Visible Safety Leadership • HomeSafe Live events i. 17 conferences across Devon, Cornwall, Bournemouth and Bristol. Led by the Senior Management Team from all departments. ii. Over 2,300 employees attended fun engaging sessions, with real-life experiences of the consequences of not ‘Taking Ownership’. iii. Leaders owning HomeSafe, celebrating success with the intention ofencouraging others to develop good practice and behaviours. iv. Leaders hosting safety ‘stand-downs’ to discuss recent events and immediate lessons to be adopted. v. The use of external expert speakers delivering real life stories of the impact of incidents. vi. A ‘12 days of Christmas’ campaign where each day for 12 days one department owned a key HomeSafe message for the Group ranging from simple pictures and messages through to scripted and acted out videos to engage the audience. 2. Driving a culture of accountability throughout the organisation: • With a focus on over 20 leading indicators, driving up performance against these areas and embedding these behaviours as the ‘way wework’. • Building on our 2.2.2 approach to incident reporting and investigating, ramping up the pace and quality of our response to ensure individuals were supported immediately in the event of an incident, improvements identified and shared rapidly across the Group. 3. Using analytics to target interventions on the key areas at the right time todrive down harm, particularly in manual handling and slips, trips and falls. These focus areas were supported through the core elements within the HomeSafe strategy, building our internal competence, elevating our Site Pride initiative across all areas, strengthening the health and safety team, achieving ISO45001 accreditation, and implementing a process safety framework. The Lost Time Injury Frequency Rate (LTIFR) for employees and agency staff continues to be the Group’s primary measure of health and safety performance. Following reductions year on year for the last three years for the Group, this year we delivered a 46% reduction in actual Lost Time Injury (LTI) numbers, with 15 LTI’s in the year compared to 28 last year, and an LTIFR of 0.30 compared to 0.59 last year. While the number of incidents reduced, we also significantly reduced the severity and impact of these incidents, through a focus on rapid intervention, treatment and support to the individual involved, delivering a 75% reduction in the actual number of days lost due to injury. This means we delivered anextra 450 productive days back into the business through improved safety performance. We continue to broaden the reach of HomeSafe to everyone working for or on our behalf, and this was in evidence at a joint event between our Bristol Water Operations team and Network Plus who provide water networks expertise within Bristol, bringing to life HomeSafe across the broader supplychain. While we have delivered year-on-year improvements, we continue to recognise that HomeSafe is not a project to be completed. It continues to be the way we work and deliver all our performance commitments. Our roadmap to HomeSafe 2025 has provided the framework to deliver improved health and safety performance across the Group. Over the year we will evolve our strategy, plans and approach to look ahead to HomeSafe 2030, building on the strong successful elements of HomeSafe while aligning our strategy to the new Group values, ensuring we support our people to be the best version of themselves and that everyone goes HomeSafe every day. Diversity, equity and inclusion As one of the largest employers in the Greater South West, we have a responsibility to promote social mobility, address inequality and drive inclusivity across our region. We continue to champion diversity and promote an inclusive workplace. Wehave published our Gender Pay Gap report for the last six years and are now pleased that this incorporates our Ethnicity Pay Gap report. These can both be found on our website: www.pennon-group.co.uk It is important to be open and transparent about the gender and ethnic diversity of our employees and this report is a key tool for us to do that, whilst also allowing us to share the measures we have taken and will be taking to continue to create a more diverse workforce across all roles and levels within the organisation. We understand that fostering an inclusive workplace is imperative for both attracting and retaining talent within our organisation. As one of the largest employers in the region, we have a duty to contribute positively within our communities, providing a work environment that promotes social mobility, celebrates and drives diversity and inclusion and ensures an equitable andpsychologically safe space for all our employees. Our business model continued 28 Annual Report and Accounts 2024 « Pennon Group plc Inclusion Week at Pennon - Sept 2023 In the latest edition of the FTSE Women Leaders Report, we have once again solidified our standing as a trailblazer for female representation, claiming the bronze position for best performers in the Women on Boards category within the entire FTSE 250. The report, independently conducted and backed by the government, is a ringing endorsement of Pennon’s relentless efforts to lead the charge in fostering equality and inclusivity, with Pennon one ofthe rare FTSE-listed entities where women on the board outnumber their malecounterparts. We are pleased with the recent progress made but know there is more todoin increasing the diversity of our workforce during the coming year. Last year, 30% of job applicants were female and similarly 30% were ethnically diverse. We offer additional support to our new employees on our graduate programme and the 10,000 Black Interns programme as we recognise many of them move to the region to start in these new positions. Employee Led Inclusion Our Employee Network Groups continue to play a significant role in raising awareness and driving change. Areas of focus for these groups include raising awareness around challenges that under-represented groups face, which has included educating employees on LGBTQ+ topics and experiences, including a session led by a transgender speaker, celebrating different cultures and customs through in-person events, sessions on racism and allyship, promoting understanding of neurodiversity, developing a webinar on sexism and misogyny and creating an ED&I awareness session, which is delivered to all new starters to the business. Recruitment We continue to develop our careers website to leverage our employer value proposition and the creative campaign that sits alongside this, #JustAddWater. We have forged new partnerships with third parties to enhance and drive our work in the recruitment space to support our ED&I agenda. In June 2023 we celebrated signing the Armed Forces Covenant andalso signed up to be a Disability Confident Employer at ‘Committed’ status during the year. We regularly review our approach to monitoring diversity and inclusion withaspecific focus on job applications. We use a software gender decoder tool which allows us to check all our job adverts for masculine bias to reduce the potential risk of alienating female applicants. We ensure that our brand imaginary represents both the communities we serve and our workforce, which encourages more diverse candidates to apply. We are pleased that we are seeing significant increases in the number of applications we are receiving from ethnically diverse applicants and women into what is still amale-dominated industry.

All of our groups have members sat on the overall ED&I Steering Group to ensure collaboration across the whole ED&I agenda and drives communication between the groups. We have also introduced flexible bank holidays, as we recognise that half ofthe UK bank holidays are linked to the Christian calendar, but many of our employees do not follow the Christian faith. The scheme enables colleagues to swap traditional bank holidays based on their religious or cultural beliefs, or personal need. Progression One of our key challenges has been enabling a diverse workforce at all levels through internal progression. The REACH (Racial, Ethnic and Cultural Heritage) Network and Women’s Network have both been key drivers in looking at how we can better support them with career progression across the organisation. This year we launched our Women’s Mentoring Programme, which supports women whether they are seeking professional guidance, building their network, or navigating their working environment and some of the challenges it entails. In January, we launched our Reciprocal Mentoring pilot, which paired eight members of the REACH Network with eight members of our executive and senior leadership team, with the goal being for individuals toshare their lived experiences and encourage actionable behaviours from those involved. We have also partnered with the Inclusive Village to design a REACH development programme. The programme is designed to support the career ambitions of those who may experience career disadvantage orinequalities due to their racial identity, whilst also enabling Pennon to foster the realisation of our commitment to the Change the Race Ratio campaign. This programme will cover a range of career-enabling topics identified by research as most pertinent in supporting ethnic minorities in the workplace, including; leveraging line manager and ally relationships, impact and influence, and developing a credible professional/personal brand. We will continue to work with these groups in relation to career progression opportunities, to understand the challenges they face, and how as an organisation we can address these. Change the Race Ratio initiative Back in 2020, Pennon pledged its support to the Change the Race Ratio initiative, a campaign to increase racial and ethnic participation in the senior leadership of companies, as a route to encouraging more diversity at all levels and was the first water company to do so. During the last year, our pledge and ongoing commitment continued to help shape our business activities and decisions. 10,000 Black Interns initiative We are pleased to be a proud supporter and sponsoring business of the 10,000 Black Interns initiative. Over the last two years we have supported 10 placements and are set to support at least 15 for this coming year. Following successful completion of their internships, most students returned to university to complete their degrees. We are pleased that so far, four of our interns have already secured permanent position on our graduate programme. This important scheme not only offers Black students an opportunity to understand our business but also to improve the levels ofethnic diversity across our industry. Our business model continued Social Mobility Business Partnership (SMBP) students visit Pennon - July 2023 30 Annual Report and Accounts 2024 « Pennon Group plc Diversity awareness and training We have continued our programme of unconscious bias training and have rolled this out to the majority of our senior leadership and hiring managers during the year. We have held ‘lived experience’ group sessions to understand what it is like to work at Pennon for employees from minority groups. Theoutputs have been shared with our Diversity Committee to understand these perspectives and consider appropriate actions when issues are raised. Our gender and ethnicity pay gap In recent years, the composition of Pennon Group has further evolved with the acquisition of Bristol Water plc and the inclusion of these employees into the growing Group. This is the second year we have included Bristol Water in the Pennon Group results and next year will be the first year we include SES Water. Our mean gender pay gap has remained fairly consistent this year and stands at 8.51%, but sits lower than the national average of 14.3%. Our median gender pay gap has seen a decrease of over 1% to 14.4%, indicative of a shift in the representation of women, notable within the upper quartiles, where we have seen an uplift from 21.4% to 25.6% in female representation, which reflects our efforts to enhance female representation at leadership levels. Since 2022, we have voluntarily produced and published our ethnicity pay gap, which stands at 11.9%. We know that there is still more for us to do in this area, including increasing the employee self-disclosure diversity rates across the Company and continuing to attract more ethnically diverse candidates atall levels across the Group. Furthermore, by offering dedicated support to new employees through the graduate programme and supporting the 10,000 Black Interns Programme, wehave been able to attract more ethnically diverse applicants. As many of these applicants are recruited and progress their careers, we anticipate them having afurther positive impact on our ethnicity pay gap. A full report breakdown and an update on our performance and plans, canbefound on our website. Social mobility We continue to be a proud signatory of the Social Mobility Pledge and have set further commitments across the Group during this year to strengthen our resolve to deliver for our customers and communities and support the drive to address social injustice. To this end we have become a tier 1 funder of the registered charity Social Mobility Business Partnership and launched work experience clusters in Exeter and Bristol with Plymouth, Truro and St Austell to follow later this year. During the FY23/24 year we have doubled our commitment to apprentice and graduate recruitment and set new targets to support 1,000 apprentices and 200 graduates on structured programmes by 2030. We have set a new commitment and target to offer 5,000 work placements for young people by 2030, significantly growing our previous work in this area. We believe this initiative is vitally important in helping young people understand our Company and the water industry, and supporting them in their early careers. Slave-Free Alliance membership Pennon has maintained its membership of the Slave-Free Alliance, which is part of Hope for Justice, the global anti-slavery charity. Our membership demonstrates our commitment to the highest employment standards for both our direct employees and those within our supply chain. Our Modern Slavery Report is published annually and can be found on our website www.pennon-group.co.uk. Human rights We are fully supportive of the principles set out in the UN Declaration of Human Rights, and the Group ethics policy outlines the high standards of employment practice with which all employees of Pennon Group are expected to comply. The Group also supports the International Labour Organisation’s core conventions for the protection and safety of employees wherever they may work throughout the Group. These standards are also embedded in our sustainable supply chain and documented in our procurement policy and Code of Conduct for supply chain partners. Pennon welcomes SES Water to the Group Pennon is delighted to welcome SES Water colleagues to the growing Pennon Group and looks forward to working with them all during the coming year. In 2024/25, SES Water will continue to deliver in line with their People Plan, the three priority areas being - Building capability for the future, Developing a culture that thrives and Enabling our business to be future ready. SES Water invest in their people through learning, development, effective communications, reward and recognition. Unlocking the potential of all their people by investing in their skills development, leadership capability, professional development, creating a performance management culture, and opportunities for career progression through internal transfers and promotions. Throughout 2023/24 SES Water delivered 934 training days, in addition to those studying an apprenticeship or professional qualification. In the past year, a new Working Group was established, aligned with the key themes of diversity, inclusion, wellbeing, the environment, and health and safety. By adopting this collaborative approach and a new internal communications plan, more opportunities have been made available for everyone to get involved with the activities they are most enthusiastic about and brings the Company purpose to life. Finally, making work life easier for colleagues through investment in new physical equipment and the HR digital transformation programme is fundamental to being ready for the future. SES Water has upgraded their people systems and processes from an online Welcome Portal for new colleagues during the recruitment process to sickness and absence management, digital correspondence and learning management. SES Water has long term commitments in the arena of social responsibility and wants their people to feel they can make a difference working as part of a business set in the heart of the community they serve. A new Working Group was established in 2023/24 which collaborates with many stakeholders to create an internal events calendar for the year, aligned with our purpose and our People Plan. This has provided colleagues with opportunities toparticipate in events and support some great local causes. 467 SES Water employees 36% Female employees 7.1% Mean gender pay gap 153 Colleague volunteering days (As at 31 st March 2024) 31Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Our operational review We are making progress in the areas that matter most, focusing onour four priorities and delivering for customers, communities and the environment. Investing to secure resilience, now and into the future Across the Group we are trusted to provide a clean, safe and reliable water supply to c.3.5million people across Bristol, Bournemouth, Devon, Cornwall, the Isles of Scilly and parts of Dorset. The health of our environment is intricately linked to the state of our water supply, so as we look to ensure robust supplies into the future, we focus on protecting the environment from which we take raw water to be treated and put into supply. Building water resources Delivering a resilient water service requires us to invest smartly in securing new sources of supply as well as reducing the demand placed on our infrastructure. Our twin-track approach has been to invest in new resources and accelerate plans for improvement, whilst seeking to tackle leakage and reduce customer demand. Our programme to diversify the Group’s portfolio of water resources in Devon is now complete, with two thirds of the programme of work in Cornwall also complete. Wet weather through 2023/24 has benefited our storage position augmenting the investments that have contributed one-third of the gains tostrategic storage in the region, with the early achievement of 100% storage for our strategic reservoirs ahead of 31 st March 2024. Supply Schemes Construction work at Blackpool Pit is now complete which brings our portfolio of repurposed quarries to four. Blackpool Pit, along with Stannon, Park and Hawks Tor, have all been used this year to support an improvement in water resources in Cornwall. In Devon, our winter pump storage work at Gatherley is also now operational, and along with the Lyd pumping scheme delivered last year, both new schemes have been used this year to support improvement in our water resources in Devon. In addition to these, our desalination plant in South Cornwall is on track to be operational in 2024/25 and our Porth Rialton water abstraction and treatment scheme will be operational under its winter licence in 2024/25. With these projects, we are improving the long-term resilience of the region following a year-long drought in 2022/23. We are on track to reach our target of a 45% increase in Cornwall water resources by 2025, having already achieved our targeted 30% increase inDevon water resources one year ahead of schedule. In Bristol, supply levels remain in surplus but our long-term plans include investment in Cheddar 2 Reservoir which will support resources across thewider South West region. Water quality Compliance Risk Index (CRI) The Compliance Risk Index score as reported by the Drinking Water Inspectorate (DWI) measures water quality compliance. Our CRI score for South West Water of 3.02 is slightly higher than last year but is again likely to be better than the industry average. We continue to make progress through our ‘Quality First’ programme with investment at our Water Treatment Works and there were no failures in the treatment processes in 2023. Our performance is above target and has been impacted due to higher incidents on our networks, particularly at consumer taps following network burst events. We have implemented an enhanced mains flushing programme to mitigate this risk further. In Bristol, our CRI performance remains challenging for the region, and performance for Bristol was a score of 7.05. Our investigations have identified the condition of the treated water tank and a valving arrangement as the likely causes for these failures. While we have implemented remedial actions, longer-term improvements are required within our future regulatory investment programmes. Further enhanced maintenance and resilience improvements are being delivered across our Bristol water treatment works with specific sites targeted for improvement. Consistent with our action plan published for South West Water, we are rolling out our Quality First programme in Bristol, targeting key areas for improvement, which includes tank cleaning and mainsflushing. Water Quality and Resilience 32 Annual Report and Accounts 2024 « Pennon Group plc Water Quality Upgrades As part of our business plan to 2025 we committed to building two state ofthe art treatments works in the Bournemouth area and work is progressing well at Alderney and Knapp Mill following planning permission being achieved at this site during the year. We are on track to achieve water into supply at Alderney by March 2025, and customers will then benefit from the enhanced ceramic membrane treatment. In addition, upgrades at four works in Devon and Cornwall are also progressing well with investments made toreduce manganese and install Granular Activated Carbon Treatment. Taste, smell and colour contacts We recognise that consumers expect their drinking water to look and taste great and that this is important in maintaining consumers’ trust in the quality of our supplies. We continue to invest in all aspects of our operations from source to tap to maintain that trust. South West Water contacts at 1.66 per 1,000 population, have increased slightly compared to last year, and are outside the performance commitment target for this year. This increase in contacts has followed a continued temporary suspension on maintenance flushing of the drinking water network during the periods of temporary use restrictions, following the drought in 2022, which in some areas lasted until September 2023. Bristol has separate regulatory targets for taste and smell contacts, as well asseparate targets for appearance contacts. 2023 saw improved performance in both of these metrics and there has been a substantial reduction in water quality contacts over this reporting period. The target fortaste and smell was achieved reflecting the Company’s focus in this area, with a systematic flushing programme which is helping to alleviate those tastes and smells that may develop in the mains water before it reaches thecustomer. Although the appearance metric was missed, this year saw the Company’s best performance in this area to date and to further improve performance, we are increasing our flushing activities across a greater proportion of the network to be flushed. Reducing leakage and supply interruptions Leakage We recognise that the prevention of water being lost in leakage from our (and customers) pipes and assets is a key issue for all customers and is something we work continuously to reduce. In South West Water we are focused on reducing leakage with a target of c.15% by 2025 (based on a three-year average). Leakage in 2023/24 has been impacted by two ‘cold snaps’ in November and January as well as a decline in the number of reported leaks (where the wetter weather has reduced the visibility water arising from leaks). This has placed greater focus on our detection activities which have increased, pressure management to continue to calm our network and using innovation. We have also focused on reducing losses from our trunk mains and continuing to support customers to identify and fix leaks within their supply pipes. Whilst this year is higher than 2022/23, the three year rolling average performance commitment has been met. Weknow that there is still more we need to do to find, fix and prevent leaks and we continue to focus on action plans to significantly reduce leakage in2024/25 to meet this target. Bristol Water has not performed well with regard to leakage. In order to make improvements going forward, we are focused on enhanced data and monitoring with c.7,000 acoustic monitors installed to support quicker and more accurate detection. In addition, a key mains replacement programme is60% complete and will support further resilience of our networks. As a result of our activities leakage in the year has reduced, but remains elevated and with the impact of the cold weather (over the last two years) we have not met our performance commitment in this area. Minimising customer supply interruptions We understand the inconvenience that supply interruptions can cause. The importance of ‘always on’ supplies, maintaining both public health and customer confidence is one of our key priorities. In both South West and Bristol, a relatively small number of events of scale have continued to impact our performance. Three significant events in Devon and Cornwall occurred in June, although these were partially mitigated through re-valving and deployment of Alternative Water Supply tankers. For South West Water, we continue to develop and deliver against our action plans, including increased 24/7 alternative water supply availability, incident management improvements, training and further calm network assessments. After June, performance in the remainder of the year returned to normal levels, however larger events continue to disproportionately impact our overall performance, which was 9 minutes 20 seconds for the year. Bristol has been primarily impacted by third-party damage in Hallen and a complex Christmas Day burst trunk main in Winterbourne – these two incidents accounted for 70% of supply interruptions in the Bristol area, with overall performance of 9 minutes 24 seconds. Whilst we have not delivered against our performance commitment this year, we expect to still be above the industry average (based on 2022/23 comparative data). Managing demand and ensuring efficiency Demand reductions To reduce demand we are focused on minimising our own use, tackling leakage and reducing customer demand through water efficiency. We have successfully reduced our own use by 11Ml/day over the last two years and we continue to improve efficiency within our processes. 33Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Per capita consumption (PCC) This measure is to incentivise companies to conserve natural resources and to target and support customers in using less water. Like all companies we saw a significant change in usage as a result of the COVID pandemic where behaviours and consumption for household customers has permanently changed. Therefore, both South West Water and Bristol Water will not meet this performance commitment this year. In South West Water we have continued our significant water efficiency programmes including: • Launching our ‘Water is Precious’ campaign– as part of this we have provided around 500 water saving devices every day this financial year. • Our North Devon smart metering programme is now 50% complete and on track for completion in 2025 – which will result in 76,000 meters deployed in this area. • Following on from the ‘Stop the Drop’ campaign last year, we launched atariff incentive so that customers in Cornwall could receive a £10 credit to their bill if they collectively reduced their water consumption by c.5% - which they achieved. • Launched our progressive charging trials for 2024/25 to include standard seasonal tariffs (both households and businesses), rising block tariffs and peak period seasonal tariff. Water efficiency initiatives in Bristol are also targeting customers to use less, through water saving devices, as well as donations to charities that promote and educate on water consumption. Water availability Following one of the hottest and driest years on record in 2022 we introduced water restrictions in Cornwall and parts of Devon which were inplace until September 2023. We have invested record amounts to deliver our drought plan and by the end of March 2024 total reservoir levels for South West Water stood at nearly 100%, ahead of our targeted levels. Whilst the recent wetter winter has helped reservoir levels, our interventions and the hard work of customers to reduce their water usage has combined to recharge our reservoirs ahead of the summer months and peak demand for the region’s water resources – with one third of capacity delivered by ourinterventions. On a longer term basis, many of the investments will deliver a sustained increase in capacity where we have seen most challenge and demand on our network, whether through the new reservoir Blackpool Pit onBodmin Moor, a new treatment works at Porth Rialton or a new desalination works in Par. We are therefore confident that there will be norestrictions in the coming year. Bristol’s water resources remain robust and storage at the ends of March 2024 was c.100%, as it was in March 2023, despite the challenges of hot, dryconditions in 2022. Maintaining asset health Mains repairs When our mains get damaged or fail, it is vitally important that these are repaired to ensure that we do not waste valuable water and that customers are kept in supply. South West Water has had a focus on optimising the operation and control ofour network by pressure management and other ‘network calming’ activities. This has included the delivery of training through our innovative network training centre. We also minimise the likelihood of mains bursts by replacing targeted sections or whole areas of poorly performing pipes. For 2023/24, our performance has returned to target in both areas, despite an increased focus from our leakage programme, with performance of 134.6 in South West Water and 124.8 in Bristol per 1,000km of mains respectively. Unplanned outages Water treatment unplanned outage provides a means of assessing reliability of our water treatment works. It tracks the temporary loss of production capacity across all water treatment works, resulting from unplanned breakdowns and asset failure. South West Water has once again met its target for unplanned outage with a figure of 1.15% compared to the industry target of 2.34%. This means we have achieved this target in each year of the current regulatory period. Thisis founded on effective investment and maintenance regimes to ensure that unplanned failures are minimised. This in turn minimises the risk of any production outages resulting in service impacts for our customers. For Bristol, outages at Purton Treatment Works, which commenced in the prior year, carried on into the early part of 2023/24. However, following resolution of the immediate issues, performance for the year achieved target with performance of 2.58% unplanned outages. A multi-year programme is ongoing to reduce future risks through the replacement of relevant assets. 34 Annual Report and Accounts 2024 « Pennon Group plc 2023 has seen some of the most tumultuous weather on record – particularly in the second half of the year. Across the South West Region, 2023 was the fifth wettest year on record, with a 34% increase in rainfall from 2022 and we experienced 50% more rainfall than the long-term average in the second half-of the year, peaking at 130% in July. We have also experienced ten named storms back to back in the latter months of the year, along with yellow weather warnings which has tested the resilience of our assets and operations. This exceptional weather continued into the early part of 2024 which has continued to place pressures on our wastewater infrastructure. The impact of the extreme weather has varied across our operations, with the wetter weather supporting the recovery of our reservoir storage and water resources, but the increased rainfall and high groundwater levels has driven up the use of storm overflows which are used in wet weather as a ‘release valve’ on the network to avoid flooding to homes and businesses aswell as increasing the number of pollution incidents in the year. Reducing flooding incidents Sewer flooding We understand how distressing sewer flooding can be and that how we react when these situations occur is a good indicator of the commitment of care to our customers. In 2023/24, despite the wetter weather, we have again seen significant outperformance, with performance of 0.76 internal sewer flooding incidents per 10,000 connections against a target of 1.44. This is a slight increase in the metric from 2022/23, resulting from a small increase in the number of overloaded sewers following heavy rainfall. We have however outperformed this target in each of the four years of the regulatory period and are one of the best performers in the industry for this measure. Despite the very high level of rainfall experienced in the winter the total number of external sewer flooding incidents has reduced by 13% compared to the prior year. Although we have missed the target for this metric (performance of 1,578 incidents with a target of 1,260), a clear focus on avoiding repeat flooding incidents with an increase of planned cleansing and routine jetting, is having a positive impact. Improving asset health Sewer collapses and blockages Targets for both sewer collapses and sewer blockages have been met for 2023/24, with performance of 11.4 collapses per 1,000km of sewer and 6,448 blockage incidents respectively. We are proud to report that 2023/24 was our best-ever performance on blockages. Proactive management of our network, including enhanced cleansing removing debris from sewers, an increase in the number of repairs as well as sewer overflow inspections being completed. In addition, a focus on improving compliance of commercial premises who dispose fat, oil and grease into our sewers, as well as other operational change initiatives, have all contributed to this achievement. Targeting improvements in the Environmental Performance Assessment (EPA) The EPA is the Environment Agency’s assessment of environmental performance. The assessment covers a combination of measures, with an overall ranking out of four stars. Our provisional rating for the 2023 calendar year is again 2 stars, maintaining improvements from the previous year. However, following the extreme levels of rainfall and high number of storms over the winter of 2023/24, the full benefits of our Pollution Incident Reduction Plan (PIRP) have not yet been seen and we have a road map to achieve a 4 star EPA status in 2025. Pollution incidents Total wastewater pollution incidents (category 1-3) remains our most challenging area. 2023 saw a deterioration in performance following the winter weather in 2023/24, which was the fifth wettest on record with a significant increase in the number of storms and intense periods of rain. The rain also led to exceptionally high groundwater, which also provides challenging operating conditions and tends to result in less time to respond to issues that arise at our treatment works pumping stations, as the issues escalate more rapidly. Despite the overall increase in pollution incidents, serious pollution incidents (category 1 – 2) have remained stable. We know there is much more to do and we continue to target a step change in performance. Our key initiatives to deliver continued improvements in pollutions performance include acceleration of additional telemetry on our sewer network (including 12,000 sewer level monitors and deployment of AI technology), continuation of our ‘hotspot’ investment programme at problematic locations and completion of a proactive rising mains replacement programme. Investment in power resilience and increased operational activities such as sewer cleansing and pumping station MOTS are all targeted in 2024. Numeric compliance Numeric permits place measurable conditions on the final effluent discharged to the environment and measure compliance with these conditions. Our performance of 96.2% was below the target for this year, following our best ever score of 99.4% in 2022/23. We experienced some challenges at individual sites over the summer of 2023/24, however we took immediate action to contain issues with activities including reedbed surveys and remediation, enhanced targeted maintenance and enhanced monitoring and review of Critical Asset Plans. We have enhanced our action plans across our treatment works, including regular reviews with the Environment Agency taking place. We are focused on delivering our 2024 target, with no wastewater failures in the first four months of the year. Storm Overflows and Pollutions 35Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Net Zero and Environmental Gains Net Zero Lowering the carbon emissions from our operational activities and throughout our supply chain is the responsible thing to do and aligns withefforts being taken by businesses, institutions and customers across the region to tackle the climate crisis and increase our resilience to climatechange. Our Net Zero 2030 plan is well underway, and we are making good progress, reducing our carbon footprint by c.45% to date against our 2020/21 baseline. Investment in renewable energy generation is an important part of achieving our Net Zero strategy and is aligned with our long term sustainable growth strategy in UK environmental infrastructure. Pennon Power Limited, a direct subsidiary to Pennon Group plc, has been formed as an entity to deliver on this element of the Net Zero strategy. Todate, investment of c.£145 million has been announced by Pennon Power in four projects across the UK, generating up to 135 GWh once operational, along with a two-hour battery system providing 30 MW of storage. When combined with the smaller scale on-site solar generation roll out, this puts the Group on track to secure c.50% of its energy from renewable sources. This strategy will also benefit the Group by reducing our exposure to future volatility in wholesale power markets that we have experienced in recent years, and will provide commercial returns ahead of those earned from the regulated water business. The sites, acquired by Pennon Power, have the required consents in place and will see construction commence in 2024, withenergisation for the full portfolio in financial year 2025/26. Our operational review continued Continued quality levels at our bathing waters South West Water has over 860 miles of coastline to protect, representing over one-third of the UK’s designated bathing waters. This is something we, and our customers, have always valued and prioritised. In the 2023 bathing water season, 100% of bathing waters (where South West Water has assets that can impact on bathing waters) achieved the stringent quality standards for the third year in a row. We were particularly pleased that the newly designated Plymouth Firestone Bay achieved excellent status. For the 2024 bathing water season, six further bathing waters in our region including four on the River Dart (Dittisham, Stoke Gabriel, Steamer Quay and Warfleet) will be included intheassessment. Tackling spills from storm overflows Despite the exceptional rainfall over the summer, we maintained 100% bathing water quality for the third consecutive year. This extraordinary weather has triggered an increase in the use of storm overflows, operating to protect thousands of homes and businesses from flooding and higher spills have been recorded from new monitors (installed at the end of 2022) with 100% coverage of our overflows. This position has been seen across the industry and for South West Water we recorded an average of 43.4 spills, compared with 28.5 in 2022. On a like for like basis (taking account of the first full year of monitoring and the impacts of exceptional rainfall and higher groundwater) the number of spills is lower reflecting the c.80 interventions delivered in 2023 and these actions will continue to support reductions into 2024. We have already ramped up our plans with c.60 interventions already delivered by the end of March 2024 – including 20 additional storm storage schemes. We are seeing tangible benefits from our interventions which are focused on not only increasing storage but reducing the water entering our systems through groundwater infiltration and surface water separation. We continue to present our storm information through WaterFit Live launched in March 2023 to cover all our bathing beaches, we are in the final stages of rolling this out across our rivers which will give live updates on all our storm overflows. Furthermore, in March 2024, we were one of the nine water companies in England that published a National Storm Overflows Plan setting out how the sector will meet or exceed all Government targets – this is the most expansive programme for overflows in the world, and South West Water hassubmitted an ambitious plan which, if approved, meets the targeted spillreduction a decade earlier than required in 2040. 36 Annual Report and Accounts 2024 « Pennon Group plc The first site to enter construction is a 45 MWp solar site with co-located battery storage in Dunfermline, acquired in May 2023. With total build costs expected to be c.£60 million, we are targeting a split connection with generation expected late in calendar year 2024, with the battery storage unit connecting in Q1 2025. A further three sites, located in Aberdeenshire, Cumbria and Buckinghamshire, were acquired in July 2023. These sites, with total anticipated build costs of c.£85 million, will add a further 98.5 MWp of generation capacity. The sites in Aberdeenshire and Cumbria are targeted to be operational early in financial year 2025/26, and Buckinghamshire following later in the year. Pennon Power continues to identify further acquisition targets and anticipates making further investments once the Dunfermline project is fullyoperational. Environmental Gains A healthy environment is important for our region, and in the face of climate change, ecological decline and greater recreational use of rivers and seas. Nature and the environment is a priority for us, as we look to work with nature to provide sustainable solutions for the challenges we face. Putting the journey to net zero and nature recovery at the heart of what we do, working with partners, means we can create climate resilient places and infrastructure. Catchment management and Upstream Thinking Since 2010, we have been working with local delivery partners, farmers and landowners to deliver our award-winning Upstream Thinking programme. Today we have well established relationships with key delivery partners across the region including Cornwall Wildlife Trust, Devon Wildlife Trust, Natural England, Farming and Wildlife Advisory Group, South West Lakes Trust and Westcountry Rivers Trust. To date, this approach has improved the management of 127,000 hectares ofland across 80% of our drinking water catchments, outperforming our target of 123,000 hectares by March 2025; this has been achieved through working with partners to deliver initiatives across the region including Exmoor, Dartmoor and Bodmin Moor. We have restored 1,550 hectares of peatland since 2020. Over 250,000 trees have been planted since 2020, meeting our 2025 target one year early. The range of pollutants which the programme helps to remove from the water course includes farming-derived nutrients, pesticides, faecal coliforms, sediment, veterinary medicines and antibiotics. The benefits of thisinvestment are reliable clean water supplies, better wastewater dilution and natural flood management. Nature recovery Our sites include reservoirs, moorlands, major operational sites, former clay pits, estuaries, farmland and forests, and small urban sites with pumping stations and pipework. Many of our sites are already well-established havens for wildlife, with some designated as Special Areas of Conservation (SAC) and County Wildlife Sites (CWS). We own and manage 1,251 hectares of Sites of Special Scientific Interest (SSSIs), of which 88.5% is in favourable condition and all but 9.5 hectares ofthe remainder is classed as in recovery. We have proven experience of habitat restoration, including land adjacent to two former industrial mining quarries in Cornwall, Park Pit and Stannon. South West Water bought Park Pit and the surrounding industrial land on Bodmin Moor in 2007. At the time, ecologists described the area around Park Pit as a “moonscape of waste sand and mica”. Fast forward to today, and the industrial wasteland has been transformed into a nature-rich heathland andreservoir. We take our biodiversity responsibilities seriously – we have surveyed our land and ensured biodiversity enhancement plans to boost nature and to monitor and control the invasive non-native species are in place for all ofoursites. Addressing Affordability and Delivering for Customers Keeping bills affordable Managing affordability starts with ensuring we deliver quality services efficiently, keeping bills as low as possible and minimising any bills rises. Soits only right that we continue to be at the forefront of the sector when itcomes to cost efficiency. In all the areas we serve, average bill increases for 2023/24 and 2024/25 were below the headline rates of inflation. Our current bill for South West Water islower in real terms today than a decade ago, bolstered by initiatives such as WaterShare+ and our innovative tariffs and incentive schemes, which give customers lower bills for lower water usage. We are pleased that our latest water efficiency tariff across Cornwall has been successful, leading to a 5% reduction in water use and a rebate on customer bills. 37Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Business Retail Pennon Water Services (PWS) PWS continues to deliver for its business customers offering a range of attractive tariffs and value-added services, whilst also delivering year-on-year improvements in its revenue, EBITDA and PBT. Serving its customers PWS maintained its focus upon high quality customer interactions, resulting in a Trustpilot of 4.8 out of 5 measured through the independent review platform comparing favourably to its peers. Its large strategic users of water rated the quality of service from their account team at 4.94 out of 5, demonstrating its ability to provide tailored support services to meet varying business needs. Its customer service teams issued over 300,000 customer bills in the year and answered over 90,000 phone calls, assisting with simple queries as well as complex customer challenges relating to their site and its future requirements. Its focus upon root causes of complaints into its own service and those it recorded against wholesalers has supported a 16.5% reduction in its volume of complaints compared to the prior year. Financial performance Revenue increased by 8% from £218 million in 2022/23 to £233.8 million in2023/24. A direct result of continued customer growth and low customerattrition despite a reduction in customer consumption in our incumbent areas. EBITDA and PBT grew by 67% and 128% in the year respectively, demonstrating its operational efficiency against its higher revenues, a disciplined approach to winning new business and control of operating costs. Since the market opened in 2017, PWS has provided strong customer support and high quality of services to maintain a stable market share of c. 6% in England and Wales. The market share for the UK is 5.2% including Scotland, serving over 154,800 business accounts (c. 95,000 customers) intotal. Our operational review continued Eradicating water poverty In 2019 we made a pledge to eradicate water poverty and ensure everyone has an affordable bill by 2025, a full five years ahead of the industry target. This was set for South West Water and Bournemouth Water, with a similar target independently set by Bristol Water, to achieve 0% in water poverty. With households feeling the impacts of the cost-of-living crisis, we have extended our package of affordability measures, unlocking £100m of financial support for customers, and we are pleased that we are on track to achieve our industry leading commitments to eradicate water poverty by 2025. Acommitment we have doubled down on in our Business Plan to 2030. 98% of South West Water and Bournemouth Water households have been independently assessed as having an affordable bill. This is up from 96.8% last year. 100% of Bristol Water customers receive an affordable bill. Over 132,000 unique customers have benefited from one or more of our affordability initiatives across South West Water, Bournemouth Water and Bristol Water to date. We are focused on lifting a further 10,000 customers out of water poverty in the next year as we continue to evolve our affordability toolkit. This includes our innovative data model allowing us to identify and auto enrol customers who are within the group who are often the most vulnerable and hardest to reach onto social tariffs. We are also continue to work with local councils and debt partners to identify customers who may be in financial difficulty and may need support. Supporting vulnerable customers Our priority services programme is underpinned by the following pillars: • Providing easy ways to register for our Priority Services Register, so those who may need support reading their bills or meters can find the right help. • Data sharing with key utility partners so customers who need extra support are added to our Register. • Ensuring customers who have needs that rely on a constant supply of water have the right help if an incident occurs interrupting that supply. WaterShare+ We have a unique structure, through our WaterShare+ scheme, which gives customers the chance to either own a share in our business or receive a reduction in their water bills. To date, we have shared £38m with customers through shares or bill reductions, and 1 in 14 households in the South West are now shareholders. We are looking to increase this to 1 in 10 by 2030 so that more customers have a stake in our business. 38 Annual Report and Accounts 2024 « Pennon Group plc PWS continued to win new customer contracts across a diverse range of business sectors. This was achieved despite ongoing economic uncertainty. The combination of strong growth in new contracts and high retention delivered a cumulative net consumption gain of c. 4% (2,105 megalitres) in the current year. As a result, PWS has taken its cumulative position since the market opened to c. 51,000 megalitres, the equivalent of c. 20,330 Olympic-sized swimming pools. New contracts in the year included Agrial Fresh Produce, Aggregate Industries, and Welcome Break. Whilst growth in new contracts continued PWS maintained its low levels of customer attrition. Our continued focus on value and service with existing customers ensured we renewed a number of contracts including Unite, GSK and Kerry Ingredients. Outlook Pennon Water Services remains well placed to deliver against its long-term strategic objectives, growing organically and sustainably, investing in its people, systems, processes, and innovative customer solutions.

Strategic report Governance Financial statements Other information 39Pennon Group plc » Annual Report and Accounts 2024 SES Water How SES Water Deliver Like the rest of Pennon Group, the SES Water approach to delivering its business model has ESG at its core. Strong Financial Governance The SES Water Board has a Code on principles of good governance (including financial governance) and assesses compliance with the UK Corporate Governance Code 2018 on an annual basis. The SES Water Board takes its obligations for good corporate governance extremely seriously and applies standards appropriate to the nature and ownership structure of the business. These standards are kept under continuous review and are amended in line with business developments and to reflect best practice. With respect specifically to Financial Governance, the SES Water Board is provided with assurance that the principles of good governance are maintained via input from the SES Water Audit Committee and the SES Water Financing Committee. The former includes insights and recommendations from the external financial auditor, PwC, on various aspects of financial governance such as internal control improvements, enhancing transparent external reporting and assessments on areas offinancial judgement, which management appropriately actions whererequired. Investing in the Environment SES Water has continued to invest in local catchment initiatives, contributing to land management changes and supporting local groups with enhanced nature conservation. SES Water achieved its third Biodiversity Benchmark with The Wildlife Trusts, delivering on their bespoke performance commitment and remain on track with their WINEP delivery. SES Water has continued with its fleet decarbonisation and energy efficiencyprojects, whilst also progressing external assurance for its GHG emissions reporting. SES Water colleagues are building strong partnerships with a range of stakeholders in readiness for their ambitious catchment work, including non-statutory proposals to invest in catchment resilience and long-term future sustainable water resources. Local estate projects are gaining momentum with integration to the South East’s regional water resource and landscapeplanning. Investing in the Community SES Water has long term commitments in the arena of social responsibility and wants their people to feel they can make a difference working as part ofa business set in the heart of the community they serve. A new working group established in 2023/24 collaborated to create an internal events calendar for the year, aligned with the SES Water Purpose and People Plan. This has provided everyone with opportunities to participate in events and support some great local causes. For example, SES Water colleagues participated in the Give A Day (153 colleagues in total) initiative, supporting a wide range of local charities including Stripey Stork, Community Fridge, The Wildlife Aid Foundation, The Orpheus Centre, The Conservation Volunteers, Crossroads Care, and Methodist Homes Association. Building relationships with local education providers further strengthens the early careers strategy implementation by continuing attendance at career fairs, offering a structured work experience week and apprenticeships. Thesemeasures are bolstered by the highly successful education programme held at the Flow Zone centre at Bough Beech Treatment Works. Health & Safety SES Water has had another excellent health and safety performance in the past year, with no Lost Time Accidents (LTAs), and no reportable incidents or injuries at year end. Numbers of minor Non-Lost Time Accidents (NLTAs) were also lower than the previous year. They were proud to achieve two RoSPA Gold Awards (The Royal Society for the Prevention of Accidents) – one for health and safety performance and the other for fleet safety and the management of occupational road risk. Delivering for its Customers SES Water prides itself on continually seeking to improve the quality of the service for its customers. The following is a summary of in year performance and Performance Commitments (PCs). Leakage The SES Water overall leakage reduction performance continues to meet its required three-year rolling target, and the Company remains on track to deliver the 15% in-year reduction required by 2025. SES Water has stayed at or below the maximum allowed level of leakage every year since the target was first set more than 20 years ago and has once again met our leakage reduction, which is industry leading. Per capital consumption (PCC) SES Water has progressed its universal metering programme and continued to support in-home water efficiency assistance. The Company also deployed a targeted water efficiency campaign from which it has gained important insight to inform its 2024 concept. SES Water has historically had relatively high PCC and whilst its 2023/24 PCC is reduced compared to 2022/23, it is in the process of designing a water efficiency pilot to inform the best value support it can give to its customers. Our operational review continued 40 Annual Report and Accounts 2024 « Pennon Group plc Improving Water Quality SES Water has continued to deliver excellent water quality performance in 2023. It has determined its Compliance Risk Index (CRI) score to be just 0.01, with only three sample exceedances for lead or nickel, linked to the condition of service pipework and customer fittings, contributing to this score. SES Water expects its performance to be confirmed as an industry leader when the DWI publishes industry results in July 2024. SES Water has had a very challenging target to minimise the number of customers that need to contact it about the taste, smell or appearance of their water. In 2023, SES Water received 0.58 contacts per 1000 population, which was above its target for the year of 0.50, and so it will receive a small financial penalty from Ofwat. Whilst it is disappointing that the business did not meet the target set, it expects its contact rate performance to continue to be in the industry upper quartile. Maintaining water resilience and asset health SES Water continued work to make sure it operates, maintains and invests in its water treatment work assets, which has ensured it has once again outperformed its target on unplanned treatment work outages, achieving 0.81% against a target of 2.34%. SES Water continues to invest in the long-term resilience of its network and remains on target to have every property connected to two water treatment works by 2025. The level of mains repairs has improved significantly since last year, but the business will not meet its target and will receive a financial penalty from Ofwat this year. Despite that, its performance will likely remain upper quartile within the industry. SES Water’s smart network, which helps it find and fix leaks in near real- time, has enabled them to reduce its leakage run times by up to 40%. SES Water are the first UK water company to roll out this intelligent technology across its entire water distribution network, with the aim of more than halving their leakage by 2045. SES Water have once again achieved its supply interruptions target as it nears the completion of a 15-year resilience programme it has been progressing since 2010. By 2025, every property across its region will be supplied by more than one treatment works if, due to operational challenges, this is needed. SES Water has also not had to implement any water restrictions within their area for over a decade.

Vulnerable support scheme awareness. 41Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Our KPIs – non-financial metrics Clean, safe and reliable water Asset Health is essential for ensuring a robust supply of water to our customers. Mains repairs performance has improved despite an increase in repairs we have undertaken to reduce leakage and address bursts, ensuring that we have meet targets in SWB and Bristol Water. In SWB, our unplanned outages increased, but remains well within the regulatory target for the year. Bristol Water unplanned outage performance improved over 2022/23, but an unplanned event at one of our largest treatment works in Bristol meant the target was narrowly missed for 2023/24. Water quality (CRI score) The Compliance Risk Index (CRI) is the Drinking Water Inspectorate’s measure of water quality. In 2023/24 we continued with our ‘Quality First’ transformation programme. Performance in our SWB region (consisting of South West Water and Bournemouth Water but not Bristol Water, which is subject to separate cost and performance reporting to Ofwat) was impacted by tanks on one site. There were no failures from water treatment processes in 2023, and our performance remains upper quartile for the industry. Bristol Water was below average but is learning from the SWW approach and applying the ‘Quality First‘ programme (rolled out with enhanced mains flushing, tank inspection and cleaning and staff survey and training) to improve Bristol Water’s performance. Performance for 2023 was impacted by 3 events at our larger sites. Supply interruptions (Duration per property per year) Performance across the Group is often impacted by colder weather and third-party damage. At SWB, 35 incidents contribute c. 5 minutes to performance, 10 events contributed c. 2.5 minutes to performance and third-party damage contributed c. 30 seconds. At Bristol Water, performance has been primarily impacted by third-party damage in Hallen and the complex Winterbourne Christmas Day burst trunk main. The two incidents have dominated performance this year accounting for c.70% of our supply interruptions (6 mins 41 secs). Our underlying operational performance indicates that the 2024/25 target level (at 5 minutes) is achievable. Taste, smell and colour (contact per 1,000 population) We recognise that customers expect their drinking water to look and taste great and this is important in maintaining customers’ trust in the quality of our supplies. At SWB our performance had been consistently improving in line with our targets, however as a result of the drought conditions in summer 2022, we limited our flushing activities in areas until restrictions were lifted which has impacted performance in 2023/24. At Bristol Water there has been a substantial reduction in appearance contacts and taste and odour contacts over this reporting period. Leakage (3-year average – Megalitres per day) Reducing leaks is a critical component of ensuring a sustainable watersupply. Most companies saw an increase in annual leakage in 2022/23 reporting higher levels of bursts resulting from a hot, dry summer and the winter freeze-thaw. Whilst leakage has remained stable in South West Water and Bristol, in the year, the position in 2022/23 has an enduring impact on the regulatory three-year rolling performance.

The 2023 weather (fifthwettest on record and increased number of storms) and operating conditions (exceptionally high groundwater and scale of rainfall) has resulted in less time to respond to issues that arise at our 655 treatment works and c.1,200 pumping stations. This has meant the benefits of our Pollution Incidents Reduction Plan (PIRP) will not be seen until 2025. Serious pollutions (category 1-2) have however remained stable this year.

In 2023 there were 151 designated bathing waters in the region, including one new bathing water at Plymouth Firestone Bay. However, only 150 bathing waters were classified as Watcombe was not classified by the EA due to access issues and so wasexcluded from the 2023 assessment (Watcombe was classified as ‘excellent’ in 2019). In 2023, 100% of our bathing beaches where South West Water assets would have an impact on the bathing beach met the high standards set forwater quality for the third year in a row (one bathing water (Porthluney) was classed as poor but SWW do not have any assets impacting this bathingwater). Average Spills Our Waterfit programme is focused on protecting rivers and seas. During 2023, the average number of spills has increased - the increase this year can be accounted for by the amount of named storms and weather warnings in 2023.

More information on pages 49 to 50 Financial highlights of the year I am excited to have joined Pennon at this time in the Company’s development. As I look back on the fourth year of our 2020-2025 business plan we continued to outperform the regulatory cost of equity, maintained financial discipline by managing gearing, raised debt to sustain liquidity and made an early start on cost reduction for K8. Furthermore, we are gaining momentum in the build out of our renewable energy generation sites through Pennon Power and see further positive progress in our non-household retail business, Pennon Water Services. In addition to our organic development, soon after I joined the Company in January, we announced the acquisition of SES Water and the £180 million equity raising to fund the acquisition. This successful transaction represents the ambitions we have as a Company to grow and be a leader in the UK Water sector whilst maintaining our commitment to financial discipline. Delivery of our regulatory programmes, the reinvestment of RORE, investing in Pennon Power and the acquisition of SES Water have resulted in the largest capital expenditure programme in one year. The level of regulatory investment demonstrates our capacity and capability to deliver at investment rates set out in our PR24 submission. As I look ahead into the fifth and final year of the K7 plan, we are working to ensure that we are in a strong position financially to support our 2025-30 business plan. We will: diversify our debt portfolio, supported by our debut credit ratings; de-gear the SES Water balance sheet; continue to achieve outperformance on regulatory returns and deliver a step change in our cost base. We have already realised c.£9 million of total benefits in 2023/24 through our existing transformation programmes (including optimisation of sites to reduce power and chemical costs and enhancing contract management processes). We expect to continue and extend this programme, with targeted annualised savings of c. £55 million during K8. We expect further sustainable growth from Pennon Water Services and are expecting Steve Buck Group Chief Financial Officer 47Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Our CFO’s review continued our first renewable energy site to start generation late in financial year 2024/25. The improving performance, following a loss before tax in H2 2023, is expected to continue to the end of K7. The start of K8 will be a point of reset for the financial position of the Group, enabling a return to stronger income statement performance and recognition of the K7 true-ups to Regulated Capital Value^ (RCV). We continue to deliver regulatory outperformance and our investments have generated RCV growth of around 10% in the year, with overall RCV growth of c.65% since the start of K7. Despite the current low level of earnings per share, there is significant retained shareholder value in the regulated business. Overall, our financial performance for 2023/24 is in line with our expectations. As we have said previously, the impact of high inflation on our cost base reduces our earnings, in particular due to power costs remaining high, and in part due to hedging our power at previous higher prices. The second half of 2023/24 experienced some of the highest levels of rainfall seen in recent times and this contributed to higher wastewater treatment costs. Despite this upward pressure on costs, we have managed to keep our regulated costs broadly flat year on year. Despite increased borrowing levels and rising base rates, our effective interest rate^, in South West Water, has remained broadly constant at 5.6% 5 (2022/23: 5.5%), with the inflationary impact on finance costs stabilising, in part through the £300 million RPI swaps that were put in place in 2022/23. Tariff increases have recovered previous inflationary cost increases. Underlying profit before tax for 2023/24 is up from £16.8 million to £19.3 million before the impact of the acquisition of SES Water, an increase of c.15% compared with 2022/23. SES Water has contributed to the financial results since 10 th January 2024 and is performing in line with our expectations, contributing £35.7 million of revenue and a £2.5 million loss before tax for the c.2.5 months of ownership.

The regulated aspect of the acquisition of SES Water is progressing through the CMA review and as expected, has been referred for a Phase 2 review under the prescribed process. The CMA has indicated that there are reasonable grounds for believing that the undertakings offered by the parties under the process might be accepted. Whilst the CMA review is ongoing, SES Water and South West Water will continue to be operated independently ofeachother. The merger of South West Water and Bristol Water completed on 1 st February 2023 with the combined water business now operating under one licence held by South West Water Limited. Within this report, to aid comparability both now and ongoing, the results of South West Water include the operating performance ofBristol Water in both 2023/24 and the comparative period, 2022/23. Group performance – summary The Group’s statutory revenue for 2023/24 was £907.8 million compared with £797.2 million in 2022/23 which included non-underlying reductions of £27.8 million in respect of the second issuance under WaterShare+ (£20.2 million) and our “Stop The Drop” demand reduction incentive (£7.6 million). Group underlying revenue increased by £82.8 million, or 10.0%, to £907.8 million, with SES Water contributing £35.7 million of the increase. Organically 6 , underlying revenue has increased by £47.1 million (5.7%) with South West Water’s revenue increased by £28.5 million with inflationary tariff increases being offset by ODI penalties and prior year over recovery of revenue. Pennon Water Services’ revenue increased by £15.8 million to £233.8 million, with new contracts, predominantly outside South West Water’s regions, contributing c.£9 million to this increase. Overall, underlying EBITDA has increased 9.9% from £307.8 million to £338.3 million with South West Water and Pennon Water Services contributing £332.5 million and £7.4 million respectively of this overall increase. SES Water contributed £3.6 million to the overall increase. 48 Annual Report and Accounts 2024 « Pennon Group plc Further details of the performance of South West Water, Pennon Water Services and SES Water are outlined below. We recognise the pressure the ongoing cost-of-living crisis puts on our customers, so we are determined to continue to assist customers with access toa broad range of affordability measures to support those in financial need. Across all Group businesses, the potential impact of significant increases in the cost of living on affordability has been considered in assessing our expected credit loss charges. Cash collections across the Group have remained robust during the financial year. Expected credit loss charges for 2023/24 of £6.3 million for South West Water (0.9% of revenue) are in line with previous levels (2022/23: 1.0%). For Pennon Water Services, the expected credit loss charge of £1.0 million (0.4% of revenue) is also in line with previous levels (2022/23: 0.4% of revenue). The Group reported a statutory loss before tax of £9.1 million (2022/23: loss of £8.5 million) after net non-underlying costs of £25.9 million (2022/23: £25.3 million). Group underlying profit before tax is in line with prior year at £16.8 million (2022/23: £16.8 million) with SES Water contributing an underlying loss before tax of £2.5 million. Organically, Group underlying profit before tax increased by £2.5 million to £19.3 million. While this outturn reflects a marginal overall improvement in earnings compared with 2022/23, it represents an overall marked improvement in performance given the challenging operating conditions, caused by the excessive rainfall during the second half of 2023/24. Underlying, organic profit before tax in H2 2023/24 was £10.2 million compared to an underlying loss of £5.7m in H2 2022/23. Segmental performance – Water South West Water Since 1 st February 2023, the trade and the significant majority of assets and liabilities of Bristol Water plc were transferred to South West Water Limited under a statutory transfer mechanism set out in the Water Industry Act. The Bristol Water brand continues as a trading name of South West Water. As noted above, the financial performance of South West Water includes the performance of Bristol Water in both this financial year and the comparative year. South West Water’s statutory revenue for 2023/24 was £729.8 million compared with £673.5 million in 2022/23. Last year’s revenue included non-underlying reductions of £27.8 million in respect of the second issuance under WaterShare+ (£20.2 million) and our ‘Stop The Drop’ demand reduction incentive (£7.6 million). Underlying revenue of £729.8 million for 2023/24 has increased by 4.1% compared with the prior period (2022/23: £701.3 million). The revenue growth of £28.5 million is explainedabove. Underlying operating costs of £397.3 million are largely flat year on year witha small increase of £4.4 million (2022/23: £392.9 million). Normal inflationary increases have been offset by early benefits from our transformation programme and continuing integration efficiencies. Energy unit prices, which were specifically impacted by high levels of inflation over the last two years are now stabilising with a year on year decrease of £1.0 million. However, in order to de-risk the business from the volatility of the wholesale energy markets, some of the recent higher power prices were locked in through our hedging strategy. We expect the impact of those to decline over the coming year. South West Water’s underlying EBITDA increased by 7.8% to £332.5 million. Underlying operating profit has increased by 6.7% reflecting the improved EBITDA performance and an increase in the depreciation charge of £13.4 million compared to last year as our accelerated capital investment programme starts to impact the depreciation charge. The net interest charge of £155.5 million is £10.2 million higher than prior year (2022/23: £145.3 million), reflecting an effective interest rate^ of 5.6% 1 (2022/23: 5.5%). South West Water’s statutory loss before tax was £1.0 million (2022/23: loss of £29.6 million) after non-underlying costs of £15.6 million (2022/23: £43.7 million). South West Water’s capital expenditure was £582.9 million, an increase of £224.7 million (62.7%) on the prior year (2022/23: £358.2 million). The final determination, Green Recovery, Defra accelerated delivery, and the RORE reinvestment were weighted towards the end of the K7. Major categories of Capital expenditure (£m) Enhancement spend has been pulled forward from year 5 to year 4 byc.£80 million due to our investment in water resources and network monitoring. This expenditure is delivering new water treatment works in Bournemouth, a desalination plant in Cornwall, additional reservoirs to improve resilience to drought, and enhanced network monitoring including acoustic loggers and sewer level monitors. Base expenditure has increased by c.£80 million as a result of spend to mitigate the impact of the weather on our assets, and the expansion of our Quality First programme across the regions. The exceptional weather we have experienced over the year has resulted in spend to minimise pollutions and spills and to drive targeted reductions in leakage. We expect 50% (£40 million) of the increase to be recovered in our RCV in K8. SES Water SES Water has contributed to the financial results since 10 th January 2024. Since that date, the business has contributed £35.7 million of revenue and £3.6 million of EBITDA to the Group results. The business continues to be impacted by high levels of financing costs which the Group intends to address where possible once it is able to leverage benefits from the Group’s financing strategy, as and when CMA clearance is obtained. In the period since acquisition, the business has performed in line with our expectations. Over the 12 month period to 31 st March 2024, SES Water has benefited from higher revenues, mainly due to tariff rises allowed under the regulatory regime and increased non-household demand. Operating costs have increased in the year, mainly driven by supply chain pressures resulting in higher electricity costs and chemical spend. Financing costs continue to be adversely impacted by high inflation on the index linked bond although this pressure is starting to reduce as RPI comes down.

Non-household demand within our wholesale water region fell due to usage; however, year on year revenue, EBITDA and profit before tax have continued to grow throughout 2023/24. The overall impact on revenues for Pennon Water Services, including the impact of new contract wins, is an increase of 7.2% compared to the prior year. New business wins have contributed £8.5 million of additional revenue compared to the last year, with inflation (net of customer attrition) contributing further to the increase. The non-household market continues to be very competitive with low margins, as a result, a clear focus on cost control and efficiencies is critical to the success of the business. The business has improved its performance year on year, with underlying operating costs growing marginally behind improving revenues, the business has improved its underlying EBITDA by c.72% to £7.4 million (2022/23: £4.3 million). This strong performance has resulted in the business reporting a profit before tax of £4.7 million (2022/23: £1.8 million), an increase of 161%. Group net finance costs Total net finance costs were £150.2 million compared to £118.2 million in 2022/23, which included a non-underlying gain of £18.4 million resulting from the repayment of the Bristol Water plc index linked bond due 2041. There are no non-underlying finance costs in 2023/24. Underlying net finance costs for the Group of £150.2 million are £13.6 million higher than last year (2022/23 £136.6 million) arising from: c.£29 million increased levels of net debt, including post-acquisition finance costs of the SES Group; continued rate rises (c.£9 million), offset by reduction in inflation (c.£15 million) and increased levels of capitalised interest on our capital programme (c.£9 million). The non-cash element of our finance charges, which accretes to the debt principal, was c.£56 million (2022/23 c.£67 million). Overall, the efficient funding mix and hedging strategy has resulted in an effective interest rate of 5.6% (2022/23 5.5%) for South West Water. The Group continues to efficiently secure funding for South West Water through its Sustainable Financing Framework and to ensure c.60% of its interest rate risk is mitigated in line with the Group Treasury Policy, which is achieved both through issuing fixed rate debt and effective interest rate hedging, with a further element being index-linked. 5.6 5.5 3.9 2.5 3.4 2022/232021/222020/212019/20 2023/24 from our associated company, in our 2023/24 results (2022/23: £0.3 million), an increase of 133%. Acquisition accounting As part of the requirements of acquisition accounting, we have determined the provisional fair values of the acquired balance sheet of SES Water. Goodwill arising from the acquisition of £15.6 million, based on these provisional fair values, has been recorded in the Group consolidated balance sheet and is attributable to the recognition of deferred tax liabilities on fair value gains recognised as part of the acquisition. The acquisition of the SES Water Group provides a strategic fit for Pennon Group plc as the Group expands its presence in water supply across Southern England. These provisional values will continue to be reviewed and will be finalised within 12 months from the date of the acquisition. The most material areas of adjustment relate to the fair value of acquired property, plant and equipment, including the network infrastructure, and the fair value of SES Water’s debtportfolio. Non-underlying items Non-underlying items for 2023/24 were a net charge before tax of £25.9 million (2022/23: net charge of £25.3 million). Non-underlying items are those that in the Directors’ view should be separately identified by virtue of their size, nature or incidence and where they believe excluding non- underlying items provides a more useful comparison of business trends and performance. The non-underlying charge includes: • £13.9 million of costs in connection with the setting up of a business transformation programme in South West Water following the merger of Bristol Water into South West Water. • £0.6 million of expenses in connection with the strategic review of renewable energy generating investments, not directly attributable to the intangible assets acquired. • £9.6 million of expenses in connection with the acquisition of SES Water and the related merger review by the CMA. • £1.8 million of further specifically identifiable costs in respect of mitigating measures and one-off expenditure to address the impacts of severe drought conditions following costs of £17.0 million incurred in 2022/23. The non-underlying charges in 2023/24 give rise to a net tax credit of £4.9 million in relation to the above items. Responsible approach to tax We are proud of our responsible approach to tax. The Group has maintained the Fair Tax Mark accreditation for the year, having been the first water company to achieve this status and holding the award continuously since2018. The overall 2023/24 tax credit for the Group is £0.6 million (2022/23: credit of £8.9 million). On an underlying basis, the net tax charge for 2023/24 for the Group of £4.3 million (2022/23: credit of £3.6 million) consists of: • Current tax credit of £0.6 million, reflecting an effective tax credit rate of 3.6% (2022/23: credit of £2.7 million, 16.1%). The reduction in rate is due to the Group generating tax losses, all of which are carried forward for future relief. These tax losses reflect the enhanced capital allowances available because of full expensing and first year allowances, along with pension payments made during recent years where tax relief is now due, and capitalised interest which for tax purposes is deductible in the year incurred. Around 50% of the Group’s capital additions qualify for enhanced capital allowances. This current tax credit relates to prior year adjustments in respect of additional interest deductions due in accordance with UK tax legislation. • Deferred tax charge of £4.9 million (2022/23: credit of £0.9 million). This primarily reflects a current year deferred tax charge in relation to capital allowances in excess of depreciation charged across the Group, largely due to full expensing, and a charge in respect of pension payments paid in previous years and where tax relief is now due. These are offset by a credit for tax losses carried forward for utilisation in later periods. The prior year deferred tax charge is £nil. Progression of effective interest rates Share of post-tax profit from associated companies The Group has a 30% interest in Water2Business Limited (W2B), a water retailer joint venture with Wessex Water. This investment is accounted for under the equity method and following a period of losses as the business reached scale, we are pleased to recognise £0.7 million of profit after tax 1. PWS - 80:20 joint venture with South Staffordshire. 50 Annual Report and Accounts 2024 « Pennon Group plc There is also a non-underlying deferred tax credit of £4.9 million in 2023/24 relating to the non-underlying items set out above. This relates to losses carried forward for utilisation in later years. Full expensing deductions which originally applied for the three years from 1 st April 2023 to 31 st March 2026 together with 50% first year allowances on long life assets and integral features, were made permanent in the recent Autumn Statement. Given the Group’s continued capital investment programme, these changes mean that the Group does not expect to generate taxable profits for the foreseeable future, and therefore does not expect to make anycorporation tax payments during this time. Earnings per share The earnings per share calculations reflect an increase in average shares due to the equity raise in January 2024. The Group has recorded a statutory loss per share of 3.6 pence per share for the year ended 31 st March 2024 (2022/23: earnings of nil pence per share). This includes a net non- underlying charge before tax of £25.9 million (2022/23: £25.3 million) and a net non-underlying tax credit of £4.9 million (2022/23: credit of £5.3 million). Our adjusted earnings per share excludes the impact of deferred tax charges and non-underlying items. For the Group, we have generated adjusted earnings per share^ for 2023/24 of 6.2 pence (2022/23: 7.3 pence). Excluding the impact of the loss generated by SES Water in the period post acquisition, our adjusted earnings per share would be 7.2 pence. Net debt movements The Group’s cash flow from operating activities for 2023/24 was £261.7 million (2022/23: £313.7 million). Cash collections have remained robust and we continue to monitor these closely and are focused on providing a broad range of affordability measures to support those in financial need. The reduction in operating cashflow reflects the lower levels of underlying profitability in the last two financial years, caused by inflationary pressures, alongside the cash impact of our Watershare+ and ‘Stop the Drop’ bill credits which were recognised the income statement in H2 2022/23. Net interest payments were £109.1 million (2022/23: £154.8 million) with the higher payment in 2022/23 driven by £51.5 million of interest paid on lease settlements relating to interest which accretes to the lease principal. Capital expenditure has resulted in an increase in capital investment cash outflows of £267.6 million to £598.1 million (2022/23: £330.5 million). This includes c.£49 million of cash outlay from the total £59 million investment recognised in Pennon Power. The acquisition of SES Water resulted in net cash outflows of £62.7 million being £90.2 million gross consideration, net of £27.5 million cash acquired. The Group’s net debt is further increased by the £360.1 million book value of SES Water’s net debt including fair value adjustments of c.£15 million at the point of acquisition. In addition, £9.6 million of acquisition transaction costs and costs associated with the CMA review have been recognised as non- underlying operating costs and cash flows. In connection with the acquisition, we completed an equity capital raise in order to ensure we maintain financial discipline with the leverage and capital structure for the Group. Proceeds from the equity raise, net of associated expenses, were £175.7 million. Other significant movements in net debt in 2023/24 include payment of our interim and final dividends for 2022/23 (£111.7 million) and £46.8 million of non-cash indexation on our loan instruments. The Group’s IFRS net debt at 31 st March 2024 was £3,809.2 million (31 st March 2023 £2,965.4 million). This includes fair value adjustments on acquired debt of £125.7 million which are released over the life of the related debt instruments. The Group’s net debt position excluding these adjustments is £3,683.5 million.

This consists of cash and cash deposits of £171 million (including £26 million of restricted funds representing deposits with lessors against future lease obligations) and £335 million of undrawn committed facilities. Afurther £500 million has been raised since March 2024, providing the Group with in excess of c.£1 billion of available liquidity, providing enough funding to support its obligations for at least the next 18 months. Since 31 st March 2023, the Group has secured c.£675 million of new debt, through its diverse portfolio of debt, consisting of: • £475 million in private placements with an average maturity of 13 years • £100 million of new term loans and leasing with an average maturity of9years • £100 million bilateral facility to support Group investments. In addition, further pre-funding of £500 million has been secured. The issuance of private placements signals the move to more benchmark- sized transactions in both the private placement and public bond markets, as the capital expenditure and ongoing refinancing continues. Our most recent private placements were at least 4.5 times oversubscribed, showing continued support for the Group. This will see South West Water obtain two strong investment grade credit ratings during 2024 and it plans to establish a EMTN 4 programme to facilitate further public issuances and maintain our diverse financing portfolio. We look to raise all new and renewed facilities under our Sustainable Financing Framework where possible with 82% achieved in 2023/24. The Group took steps during the previous financial year to re-balance the proportion of index-linked debt to align with previously maintained levels for the longer-term. Whilst the current level is around 20% including SES Water we expect this to increase in March 2025 as the swaps mature. Resulting from the changes above and drawing of new debt during the year, South West Water gross debt at 31 st March 2024 was £3,323 million (31 st March 2023 £2,918 million). The debt has a maturity of up to 33 years with aweighted average maturity of 13 years. 1. Reflecting £90.2 million on acquisition of SES Water, offset by £27.5 million cash acquired. 2.

Euro Medium Term Note. 51Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Our CFO’s review continued South West Water 1 net debt at 31 st March 2024 is a mix of fixed / swapped (£2,147 million, 65%), floating (£696 million, 21%) and index-linked borrowings (£452 million, 14%), which reflects our diverse debt portfolio and compares to an industry average 2 of fixed / swapped 40%, floating 7% and index-linked 53%. New debt raised during this regulatory period has been fixed to align to iBoxx indices in line with Ofwat’s approach to allowed cost of debt. Where appropriate, derivatives are used to fix the rate on floating ratedebt. At 31 st March 2024, South West Water’s net debt to RCV ratio 3 stood at 63.5% (31 st March 2023 60.8%). This is due to increased capital expenditure and reduced operating cashflows. South West Water’s cost of finance, with an effective interest rate in 2023/24 of 5.6% 1 , continues to benefit from the diverse portfolio of debt. Strong investment grade gearing levels As we progress through the remainder of K7, we expect the mix of our debt portfolio to evolve. We are currently considering the most effective debt structure to provide best value for our shareholders whilst maintaining theflexibility to adjust to market challenges and to remain within our treasury policy of at least 60% fixed rate debt throughout the current regulatory period. As the Group continues to grow through capital investment in our infrastructure so will our funding requirements. In the coming years, weexpect the Group to manage its portfolio with larger, and more diverse debt instruments, taking advantage of the public ratings once established. The Group plans to raise c.£500 million in new funding by March 2025 tocomplete the K7 business plan. We will continue to maintain a diverse portfolio of debt to support flexibility and growth opportunities. In the long term, this investment will provide returns through K8 revenues and a higher RCV. As we look to obtain strong investment grade credit ratings during the year, a target gearing level of below 72% will need to be maintained and South West Water remains well within the level. As the year progresses, further clarity will be provided through the draft and final determinations. The Group and Water business balance sheets will be optimised post SES Water CMA clearance and the PR24 outcomes. The start of the new PR24 business plans, in April 2025, will provide a point of re-set and policy review. Retaining value in the regulated business In the first four years of K7, South West Water has created c.£820 million of value for the Group from base returns, RORE outperformance and the growth in RCV. The South West Water Board has taken a prudent approach to its dividend payments in making distributions to Pennon Group and as result c.£250 million has been distributed in K7 to date. This results in over £500 million of retained value in South West Water, which the South West Water Board will consider as K7 closes. Internal borrowing South West Water’s funding is treated for regulatory purposes as ring-fenced. This means that funds raised by South West Water are not available for other areas of the Group. Bristol Water was transferred to South West Water in February 2023 and all the debt is now managed on the South West Water standard covenant package as unsecured and unrated. Following its acquisition, SES Water continues to maintain its current Group structure, which will be reviewed as part of the integration process. Pennon Water Services funding is predominantly provided by Pennon. Pennon will continue to use funds to support the Group’s ongoing operations as appropriate. Taxation strategy Transparency remains a critical component of our approach, recognising that openness and honesty with our customers is essential. Optimising our tax position benefits them, for example by keeping water bills down, but we do not enter into artificial tax arrangements, use tax havens or take an aggressive stance in the interpretation of tax legislation. As a long-term business with a long-term approach to financial management, there have been no changes to the Group’s overall tax strategy this year compared to last. We continue to hold the Fair Tax Mark. Launched in 2014, the Fair Tax Foundation’s purpose is to encourage and recognise businesses through their Fair Tax Mark accreditation scheme. This is an independent accreditation scheme for businesses paying their fair share of corporation tax and reporting on their tax practices transparently. We have also inspired other water companies to apply for the accreditation, thereby improving the tax transparency of the sector in which we operate. Under our tax strategy we: • At all times, consider the Group’s corporate and social responsibilities in relation to its tax affairs. • Operate appropriate tax risk governance processes to ensure that the policies are applied throughout the Group. • Comply with our legal requirements, file all appropriate returns on time and make all tax payments by the due date. • Consider all taxes as part of ongoing decisions. • Do not enter into artificial tax arrangements nor take an aggressive stance in the interpretation of tax legislation. • Do not undertake transactions that are outside the Group’s low-risk appetite for tax or not in line with the Group’s Code of Conduct. • Engage with HMRC in a proactive and transparent way and discuss our interpretation of tax laws in real time, such interpretations following both the letter and spirit of the laws. 1.

Further details are given in the Group’s tax strategy report available on the Pennon Group website www.pennon-group.co.uk Tax contribution 2023/24 – borne/collected The Group’s total tax contribution (TTC) for 2023/24 amounted to £100 million (excluding £144 million of VAT receipts) (2022/23 £95 million excluding £150 million of VAT receipts). TTC is a standardised measure ofagroup’s total tax contribution, having been developed by PwC and the 100 Group (FTSE 100 Finance Directors). It is acknowledged as being a fair and comparable representation of total tax cost. TTC looks at taxes borne, and taxes collected. Taxes borne includes all taxes which are a cost to the Group, such as business rates, corporation tax and employers’ National Insurance contributions (NICs). Taxes collected and recovered highlights where the business is collecting tax on behalf ofHMRC. Employment taxes totalled £52 million (2022/23 £41 million) including employees’ Pay As You Earn (PAYE) and total NICs. The total amount of £52 million includes PAYE of £5 million (2022/23 £4 million) on pension payments made by the Group pension scheme. A net amount of £37 million (2022/23 £30 million) was collected on behalf of the authorities for employee payroll taxes. Business rates of £30 million (2022/23 £35 million) were paid to local authorities. This is a direct cost to the Group and reduces profit before tax. UK Corporation Tax receipts from HMRC in the year were £3 million (2022/23 £1 million payment) in relation to over-payments made in prior years. There were no payments due in respect of 2023/24 as the Group has generated tax losses in the year. Payments to the Environment Agency and other regulatory bodies total £20 million (2022/23 £17 million). This reduces profit before tax. Fuel excise duty of £1 million (2022/23 £1 million) related to transport costs. This reduces profit before tax. VAT repayments of £144 million (2022/23 £150 million) have been received by the Group from HMRC. VAT has no material impact on profit and is excluded from the TTC figure to avoid distortions in this. Contingencies Ofwat and the Environment Agency (EA) announced an industry-wide investigation into sewage treatment works on 18 th November 2021. On 27 th June 2022, as part of its ongoing investigation, Ofwat announced enforcement action against South West Water Limited, the company is now included alongside five other companies which received enforcement notices in March 2022. The Group continues to work openly with Ofwat to comply with the notice as part of this ongoing investigation. The Group has undertaken its own internal investigation and investment interventions have been undertaken at a small number of our sites. In addition, the Group has looked for opportunities for additional future investment to include further storm storage and an extension of its sewer misuse programme which has been shared with Ofwat. Ofwat have yet to formally respond on the investigation and the timing ofaresponse is unknown, although has been potentially indicated for Summer2024. Until such time that an initial response is received, the potential outcome of these investigations continues to be unknown. Ofwat has a range of options that it could apply from closing the investigation with no further action, agreeing to formal S.19 undertakings through to fining the Group up to 10% of its revenue in relation to the regulated wastewater business. Given the wide range of possible outcomes therefore the potential outcome of this investigation continues to be unknown, and it is not possible to estimate anyobligations arising from the investigation with any certainty. On 23 rd May 2023 Ofwat announced an investigation into South West Water's 2021/22 operational performance data relating to leakage and per capita consumption. This operational performance data was reported in South Employment taxes: £52m Business rates: £30m Corporation tax: £-3m Environmental payments: £14m Fuel excise duty: £1m Other: £6m £100m TOTAL West Water's Annual Performance Report 2021/22. This report is subject to assurance processes which include independent checks and balances carried out by an external technical auditor. The Group continues to work openly and constructively with Ofwat to comply with the formal notice issued to South West Water as part of this investigation. The Group has undertaken its own internal investigation into the data and third party experts have concluded the calculations are within a tolerance as reported, as a result there were no detrimental impacts to customers through Outcome Delivery Incentives (‘ODIs’). The Group recognises opportunities to enhance data quality to improve the estimation process and these have been shared withOfwat. Until such time that an initial response is received, the potential outcome of these investigations continues to be unknown. Ofwat has a range of options that it could apply from closing the investigation with no further action, agreeing to formal S.19 undertakings through to fining the Group up to 10% of its revenue in relation to the regulated drinking water business. Given the wide range of possible outcomes therefore the potential outcome of this investigation continues to be unknown, and it is not possible to estimate any obligations arising from the investigation with any certainty. Pensions At 31 st March 2024, the overall surplus on retirement obligations of £26.6 million compares to a surplus of £29.3 million at 31 st March 2023. The small reduction in the overall Group surplus in 2023/24 of c.£3 million reflects: • c. £8 million net reduction in surplus of the Group’s principal pension scheme, Pennon Group Pension Scheme (PGPS), recognised in other comprehensive income, reflecting adverse experience losses on deferred revaluation and pension increases, offset by favourable movements in gains in demographic assumptions. • c. £3 million recognition of net pension surplus acquired with SES Water. • c. £2 million increase on Bristol Water scheme surplus arising from change in income tax rate which is applied to restrict the surplus recognised. The triennial valuation of PGPS as at 31 st March 2022 was finalised in March 2023 and no deficit recovery contributions were required. The ongoing funding requirements for the Company to the scheme are limited to the continuing administration expenses. The Group pension surplus includes a net surplus of c.£9 million (31 st March 2023: c.£7 million) relating to the Bristol Water Section of the Water Companies Pension Scheme (WCPS). The gross surplus remains largely unchanged as the liabilities of the scheme are fully insured through a bulk annuity policy. The net surplus has increased as the tax rate on the restriction applied to the surplus under UK tax legislation has reduced from 35% to 25%. The trustee of WCPS Total Tax Contribution 53Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information continues to work through the process to wind up the Bristol Water section of WCPS and has indicated its intention to return the surplus to the Company. The net surplus recognised from the SES Water acquisition reflects the surplus in the SES Water section of WCPS. The trustee of WCPS has recently fully insured the liabilities of the scheme through a bulk annuity policy. The surplus has been restricted for income tax, consistent with the Bristol Water scheme. Dividends The Group continues to strive to deliver on its commitments to customers, shareholders and stakeholders as our investments drive strong and sustainable results. Around 50% of Pennon’s shareholders are UK-based investors including individuals, pension funds, and charities. Over a third of the Group’s c.3,500 employees (excluding SES Water) are shareholders and following the second issuance of our unique WaterShare+ initiative, around 90,000 customers are now also shareholders. Pennon’s 2020-2025 dividend policy of growth of CPIH +2% reflects the Board’s ongoing confidence in the Group’s strategy and is underpinned by continued RORE outperformance in South West Water. The Board has recommended a final dividend of 30.33 pence per share for the year ended 31 st March 2024. Together with the interim dividend of 14.04 pence per share paid on 5 th April 2024 this gives a total dividend for the year of 44.37 pence. This represents an increase of 3.84% on 2022/23 which is per our policy (March 2024 CPIH + 2%) with a 1.96% reduction for the £2.4 million fine from the Environment Agency. Pennon offers shareholders the opportunity to invest their dividend in a Dividend Reinvestment Plan (DRIP). The proposed dividends totalling £126.9 million are covered 2.7 times by underlying EBITDA (2022/23 2.8 times). Pennon Group plc has substantial retained earnings and a sustainable balance sheet to support its stated dividend policy. The strong fundamentals of its principal operating subsidiary, South West Water Limited, underpin this policy with its strong RORE and growing RCV. Dividends are charged against retained earnings in the year inwhich they are paid. Investing for sustainable growth – renewable energy generation In line with both our long-term sustainable growth strategy in UK environmental infrastructure and our commitment to deliver Net Zero by 2030, we have committed c.£145 million for investment in renewable energy generation. This strategy will also benefit the Group by reducing our exposure to future volatility in wholesale power markets and will deliver attractive and sustainable financial returns. Pennon Power, a wholly owned subsidiary to Pennon Group plc, has acquired the rights to build four solar farms, one of which includes a co-located battery storage asset in the UK. Specifically these investments include: • A co-located solar (45 MWp) and battery storage (60 MWh) site in Fife, acquired in May 2023. This is a ready to build site, with consents in place, with total build costs expected to be c.£60 million. Solar generation is expected to be c.39 GWh commencing at the end of next financial year 2024/25. • A further three sites, located in Aberdeenshire, Cumbria and Buckinghamshire, acquired in July 2023. These sites, with total anticipated build costs of c.£85 million, are expected to provide a further 98.5MWp of generation capacity, generating c.96 GWh and are targeted to be operational during 2025 and first half of 2026. Of this overall commitment, we have incurred total costs of c.£59 million for the acquisition of these sites and construction costs to date on our first project at Fife. This is expected to commence energy generation late in financial year 2024/25. Aberdeenshire and Cumbria sites will enter construction during late summer 2024 and Buckinghamshire in 2025. The financial contribution will accelerate in financial year 2025/26 and all four sites will generate income during 2026/27. Return on Regulated Equity^ During K7 to date we have continued to deliver South West Water group RORE performance (excluding SES Water) of 7.3% cumulatively, equating toc.£160 million of outperformance. This consists of c.£255 million financing outperformance, net of c.£60 million totex^ overspend, and c.£35 million ODI net penalty impact. This has enabled the funding of additional capital investment initiatives as noted above. The cumulative benefits from the structure of our debt book on financing costs persist, but have reduced due to the impact of falling inflation. Totex performance has been impacted in year due to peak levels of capital expenditure following past outperformance. ODI performance across the South West Water group in 2023/24 has been impacted by the extreme weather events, including heavy rainfall through to March 2024. As a consequence, South West Water has incurred a penalty of c. £12.1m 3 (FY2022/23: penalty c. £4.2m). South West Water continues to build on its ODI performance with c.70% either on track or ahead of target 1 across abroad range of challenging bespoke, common, and comparative measures. This performance will contribute to the potential ODI award at the end of K7. ODI performance for Bristol Water is on track to achieve c. 70% of its ODIs and has resulted in a net financial penalty of c. £1.7m 9 (FY2022/23: penalty of c. £5.9m). Financial outlook 2 Looking to 2024/25, we expect overall organic revenue growth with the combined impact of inflation on our 2024/25 tariffs (net of the year on year impact of regulatory adjustments and ODI penalties) and ongoing expected growth in our non-household retail business. The full year impact of trading at SES Water will improve this further. Overall, we expect total operating costs in South West Water to be broadly flat compared to 2023/24 levels. Total power costs 4 in 2023/24 were £110 million (wholesale costs £73 million, non-commodity costs £37 million). Whilst wholesale power cost levels are falling, we anticipate a more modest improvement in our overall power costs as the impact of hedging over the last two years continues to unwind. These expected reductions coupled with other efficiencies from our transformation programmes will be largely offset by normal inflationary pressures on other input costs. In particular we continue to recognise the pressures of the cost of living on our colleagues and pay increases of c.4% have been agreed. Total Group operating costs will increase overall, with growth in the non-household retail business outside our region increasing wholesale water costs, and the impact of an additional nine months of trading at SES Water. Further increases in depreciation are expected as a result of our capital investment programme and the full year impact of SES Water. Increased debt levels to support our capital investment profile are expected to result in an overall increase in net finance costs. The total Group net finance costs are also expected to increase with the full year impact of SES. Overall capital expenditure is expected to reduce in 2024/25. In South West Water, following the peak in 2023/24, we expect overall capital expenditure of c.£930 million in the last two years of K7. However we will continue to assess the benefits of early start expenditure for K8. The build-out of our Pennon Power renewable energy sites will continue. The full year impact of SES Water will represent a small increase in our overall capital expenditure. We remain in a strong position from a liquidity perspective with additional facilities already raised in the early part of the year, and with further programmes planned, supported by our plan to have two strong public ratings by the end of the year.

The consideration of these risks and the effectiveness of their management against the desired risk appetite is informed by, and reviewed against other data points including; key performance metrics, operational insights, theoutcome of assurance activities and broader geopolitical and economicdevelopments. This is underpinned by an established risk management framework which forms part of our governance structure and is embedded into our processes, culture and ways of working ensuring that there is robust identification, review, challenge and assurance over the management of both our current and emerging risks and opportunities. The long-term success of the Group is dependent on the effective management of risks and opportunities and remains a key focus for the Pennon Board andExecutive. The Group’s risk management framework considers risk from both a strategic (top down) and tactical (bottom up) perspective. This enables a common understanding of risks and opportunities and their interdependencies, allows risks and opportunities to be cascaded and escalated effectively andprovides amulti-layered approach to the review and challenge of risk.

Severe <2% Profit AfterTax 2-5% Profit After Tax 5-7.5% Profit After Tax >7.5% Profit AfterTax A consistent methodology is applied when assessing the Group’s risks and opportunities (including climate-related risks and opportunities), which considers both the likelihood of a risk occurring and its potential impact. Risk impact is assessed across various financial and non-financial categories including: financial, safety, environmental, stakeholder and customer impact, reputation, sustainability, and quality. Likelihood is defined as the probability of a risk event occurring over the next five years under four categories (probable, possible, unlikely or rare) with defined probability thresholds. Risks are assessed on both a ‘gross’ (without the consideration of existing control measures) and ‘net’ (with consideration of existing control measures) basis enabling the effectiveness of control measures to be assessed and assured. The combined impact and likelihood determines the overall Red, Amber, Green (RAG) risk rating which is assessed against the relevant risk appetite to determine and prioritise further action. Environmental, social and governance risk management Our purpose and values recognise the broader societal role that the Group plays within the regions and communities it serves. Consequently environmental, social and governance (ESG) considerations are at the heart of the Group’s activities and how we operate as a responsible business. Theidentification, assessment and management of ESG risks and opportunities is integrated into the Group’s overall risk management framework and methodology. The delivery of ESG metrics and targets, and the associated risks and opportunities, are monitored thorough the ESG framework by the ESG Committee. Further detail is provided on page 144. As the owner of a water and wastewater company, the Group acknowledges the fundamental impact that climate change has on the Group’s strategy andpriorities and is considered to be pervasive across the Group’s principal risk profile. The assessment of the individual principal risks, as detailed within the table below, has included the consideration of both physical and transitional climate change influences, where relevant, and the mitigating actions being taken. Further detail on the specific physical and transitional climate change risks and opportunities relevant to the Group, along with mitigating actions being taken, are detailed further within TCFD on pages 78 to 110. South West Water technical (non-financial) data In addition to the risk management framework detailed above which applies across the Group, recognising the importance of the regulatory ODI framework, South West Water engages independent, third-party auditors to audit the accuracy of the technical (non-financial) data reported within the various annual performance reports and regulatory publications and submissions, including its performance commitments and environmental data. Furthermore, a third party provider, DNV, has also performed additional assurance work over selected sustainability measures. Continuous improvements to risk management andinternal control The Group is committed to continuously improving its ability to identify and respond to current and emerging risks. Examples of risk management improvements during the year include: • The Group’s confidential Speak Up process has been reviewed and furtherenhanced. • A dedicated second line function has been established focused on environmental permit assurance across the Group’s water and wastewater sites, providing an additional layer of assurance in this area. • South West Water has successfully achieved external ISO45001 accreditation of its Occupational Health and Safety Management System. • The formation of the Operational Risk and Assurance Steering Group has enhanced the bottom up process through the collective review and discussion of key tactical risks, enabling greater collaboration andinnovation. Sutton and East Surrey (SES Water) Risk Management Framework Following the acquisition of Sutton and East Surrey Water (SES Water) plc on 10 th January 2024, the transaction is currently subject to review by the Competition and Market’s Authority. In line with the requirements of the CMA’s Initial Enforcement Order (IEO) SES Water has continued to operate separately from the wider Pennon Group. Throughout 2023/24 SES Water has continued to operate their established risk management framework and processes to identify, manage and mitigate risks. This has included regular review of the SES Water principal and emerging risks and mitigation strategies by the Executive Management Team and twice a year principal risks are reviewed by the Audit Committee who report to the SES Water Board. SES Water will continue to separately operate their risk management processes until such a time that regulatory approval is received. 56 Annual Report and Accounts 2024 « Pennon Group plc Management of South West Water within the Group’s risk management framework Pennon manages its risks in such a way that South West Water, as a regulated company, is protected from risk elsewhere in the Group. TheGroup’s principal risks and uncertainties include those Group-level risksthat could materially impact on South West Water. Pennon’s risk management and internal control frameworks ensure that it does not take any action that would cause South West Water to breach its licence obligations. Further, the Group’s governance and management structures mean that there is full understanding and consideration of South West Water’s duties and obligations under its respective licences, aswell asan appropriate level of information sharing and disclosure to give South West Water assurance that it is not exposed as a result of activities elsewhere within the Group. Horizon scanning Emerging risks and opportunities are considered to be factors or events which could have a future impact on the achievement of the Group’s strategic priorities, but lack the required clarity or certainty in order to adequately assess their impact. Horizon scanning of emerging risks and opportunities is embedded within the risk management process. Emerging risks are reviewed by the Pennon Executive and Pennon Board as part of their regular assessment of the Group’s risk profile. Notable emerging risks and opportunities are detailed within the table below: Risk appetite There are inherent risks that exist within the water sector and all risk cannot be completely eliminated in the delivery of the Group’s activities. The Group therefore seeks to strike an appropriate balance between risk and reward which aligns not only with the Group’s strategic priorities but also its purpose and values. Recognising that it is not possible to apply a single risk appetite to all risks that the Group is exposed to, the Board has developed overarching risk appetite statements foreach risk category which then informs the risk appetite statement for individual principal risks. This allows the business to pursue value-enhancing opportunities, while maintaining an overall level of risk exposure that the Board considers to beappropriate. The risk appetite statement for each risk category is detailed below: Geopolitical Tensions Comment Risk category Time horizon Increased escalation of conflict in the Middle East combined with the ongoing war in Ukraine could further impact the global economy, heighten energy resilience risks and disrupt key supply chains such as chemicals. • Market and Economic Conditions • Short- Medium term Artificial intelligence and machine learning Comment Risk category Time horizon There is a risk that automated intelligence and learning deployed within operational processes develops faster than Government regulations and standards. • Operating performance • Long term Quality of water resources Comment Risk category Time horizon Changes in regulatory requirements over the treatment of micro-plastics, micro- pollutants and ‘forever chemicals’ (e.g. PFAS) as a result of ongoing research may require significant changes in operational processes in the water treatment process. • Operating performance • Business Systems and Capital Investment • Medium- Long term Changes to demographics within the areas that weserve Comment Risk category Time horizon Increases in population migration to the South West due to climate change and an increasingly aging population could place greater demand on our resources and assets. • Operating performance • Long term Law, regulation and finance Risk Appetite The Board is committed to complying fully with, and being seen to be complying with, all relevant laws, regulations and obligations and has no appetite for non- compliance in this area. This includes, but is not limited to, environmental and health and safety laws and regulations. The Group also operates a low risk appetite in respect of our financing strategy, ensuring our long-term financing commitments are met. The Board acknowledges, however, that the Group operates in a complex environment influenced by Government and regulatory policy. Consequently, there is a greater risk appetite in these areas whilst seeking to mitigate any potential downside and leverage opportunities that may arise from Government policy and regulatory change. Market and Economic Conditions Risk Appetite The Board recognises that the Group’s activities are exposed to changes in macroeconomic and external market conditions. The Group seeks to take well- judged and informed decisions to mitigate these risks where possible but accepts that a level of residual risk may remain beyond the Board’s control. Operating performance Risk Appetite Whilst the Board recognises that unforeseen events do occur from time to time, the Board has no appetite for significant operational failure of our water and wastewater assets and seeks to reduce both the likelihood and impact through long-term planning and careful management of our operational assets. There is greater appetite for well-informed risk taking to develop further markets, subject to this not detrimentally impacting on the level of service expected of our regulators, customers and wider stakeholders. Business Systems and Capital Investment Risk Appetite The Board has a low risk appetite for risk associated with the delivery of capital investment within our regulated business plan. There is greater appetite for broader value accretive investments with risk weighted against the expected level of return on a case-by-case basis and subject to this not detrimentally impacting on the level of service expected of our regulators, customers and wider stakeholders within our core water business. The Group seeks to minimise technology and security risk to the lowest possible level without detrimentally impacting on the Group’s operations. 57Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Our risk management continued Principal risks and uncertainties During the year the Board has carried out a detailed review of the Group’s principal risks in the context of the Group’s strategic objectives and priorities as well as the external environment within which it operates. This has included: • Confirming that the Group’s risk appetite statements remain appropriate. • Receiving and reviewing updates on the Group’s principal risks, including movements in the risk exposure. • Undertaking horizon scanning of emerging risks and trends. • Performing deep dive reviews into key risk areas. • Through the Audit Committee, confirmed the effectiveness of the risk management and internal control framework. This has resulted in the following material changes to the Group’s principal risks compared with those previously reported: • The water resources and operational water treatment risks have been combined into a single drinking water principal risk, reflecting the interconnectivity ofthese individual elements. • Delivery of the Group’s net zero programme has been removed as a standalone principal risk and instead reflected within the delivery of the Group’s broader environmental commitments and associated risks. • A new principal risk has been established reflecting the ongoing CMA process over the SES Water acquisition. These principal risks have also been considered in preparing the viability statement on page 65. 58 Annual Report and Accounts 2024 « Pennon Group plc58 Annual Report and Accounts 2024 « Pennon Group plc Overview of Pennon’s principal risk profile The chart below summarises the net risk assessment of the Group’s Principal risks relevant to the risk categories.

Mitigation There remains a significant focus on the water sector across all political parties ahead of a General Election which is expected to take place later in 2024. We actively engage and respond to policy consultations and the Group regularly engages with a MPs and other political stakeholders, both directly and via Water UK. This includes highlighting the impact that our proposed capital investment of £2.8bn in the next regulatory period will have on our operational performance as well as our wider contribution to society and the economy. Additionally, horizon scanning of emerging changes in Government policy, including climate change related policies, is regularly undertaken to monitor andassess the potential direct or indirect impact on the Group. Appetite We recognise that Government policy evolves which presents both risks and opportunities. The Group seeks to minimise the potential risks and maximise opportunities through regular engagement and robust scenario planning. Net risk/ Direction of travel Principal risk B Changes in regulatory frameworks and requirements Strategic impact Strategic priorities 1, 2, 3, 4 Climate change influence T Nature related influence T Changes to regulatory frameworks may impact on the deliverability and affordability of the Group’s priorities, which can impact shareholder value. Mitigation South West Water has an established and experienced regulatory function. Arobust governance framework remains in place over the PR24 business plan. Following the submission of South West Water’s business plan in October 2023, South West Water has been working proactively with Ofwat and other regulators as part of Ofwat’s standard review process. A significant degree of uncertainty will remain until such time that Ofwat confirms their Draft Determination, particularly whether the levels of funding approved will be sufficient enable the significant levels of investment set out within the business plan. Appetite We accept that regulatory frameworks evolve which creates both risks and opportunities. We seek to minimise the potential risks by targeting changes which are NPV neutral over the longer-term to protect customer affordability and shareholder value. Net risk/ Direction of travel Principal risk C Non-compliance with lawsand regulations Strategic impact Strategic priorities 1, 2, 3, 4 Climate change influence T P Nature related influence T P The Group is required to comply with a range of regulated and non- regulated laws and regulations across our businesses. Non- compliance with one or a number of these may result in financial penalties negative impact on our ability to operate effectively and reputational damage to the Group. Mitigation The Group operates within robust and mature frameworks, which includes second line compliance functions, ensuring compliance with permit and other requirements of Ofwat, the Environment Agency and other relevant regulators. These frameworks are regularly reviewed and assured to ensure the Group remains compliant with the increasingly complex legal and regulatory landscape. The control framework has been further enhanced during the year with the creation of a dedicated internal Environmental Permit Assurance Team. The Group also maintains a comprehensive internal framework, overseen by the Legal Compliance function, to ensure compliance with corporate laws applicable to public limited companies, reinforced through key policies approved by the Pennon Board and compliance training provided to staff. The Group operates a confidential whistleblowing process which has been comprehensively reviewed during the year. This is overseen by the Executive- led Ethics Management Committee. There remains an increased appetite amongst regulators for pursuing enforcement action for perceived non-compliance with industry-wide investigations of wastewater treatment works permit compliance ongoing. Appetite The Group maintains the highest standards of compliance and has no appetite for legal or regulatory breaches.

Breach of covenants could result in the requirement to repay certain debt. Mitigation The Group has well established treasury, funding and cash flow arrangements inplace, underpinned by a Treasury Management Policy endorsed by the Pennon Board. The Group’s financing commitments and cash flow, funding and covenant compliance is regularly reviewed by the Pennon Executive and Pennon Board. Since March 2023 over £700m has been secured through the Group’s Sustainable Financing Framework. The Group retains £601.4m of cash and committed facilities as at 31 st March2024. Appetite The Group operates a prudent approach to our financing strategy, maintaining an appropriate mix of cash and pre-funding facilities, to ensure our funding requirements are fully met. Net risk/ Direction of travel Principal risk E Non-compliance or occurrence of an avoidable health and safety incident Strategic impact Strategic priorities 1, 2 Climate change influence P Nature related influence P A significant health and safety event could result in financial penalties, significant legal costs and damage to the Group’s reputation.

Established health and safety training, procedures and reporting systems are complimented with site based investment, regular site visits by senior staff, initiatives such as Site Pride and Homesafe Live as well a regular programme ofwellbeing events. Health and safety performance is monitored by the Pennon Executive and therespective Board and Executive Health and Safety Committees. During the year South West Water successfully achieved ISO45001 accreditation of its Occupational Health and Safety Management System and the Group achieved its best ever health and safety performance with 15 LTIs during the year – a reduction of 46% on the prior year. Appetite The Group has no appetite for health and safety related incidents and maintainsthe highest standards of compliance for our staff, contractors and other third parties. Net risk/ Direction of travel Principal risk F Failure to pay all pension obligations as they fall due and increased costs to the Group should the defined benefit pension scheme deficit increase Strategic impact Strategic priorities 3 Climate change influence n/a Nature related influence n/a The Group could be called upon to increase funding to reduce the deficit, impacting our cost base. Mitigation The Group has in-house pensions expertise supplemented by external specialists, including professional advisors who manage the scheme’s investment strategy. The Pennon Group Pension Scheme is overseen by an independent Board ofTrustees. The liabilities of the Bristol Water Section of the Water Companies Pension Scheme are fully insured through a bulk annuity policy. As at 31 st March 2024 the Group’s pension schemes remain in surplus of £26.6m. The triennial valuation of PGPS at 31 st March 2022 did not require any deficit recovery contributions. Appetite The Group will ensure that all obligations are met in full but seeks to manage this without unnecessary costs to the Group. Net risk/ Direction of travel 61Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Market and economic conditions Principal risk G Macroeconomic near term risks impacting on inflation, interest rates and power prices Strategic impact Strategic priorities 3, 4 Climate change influence T Nature related influence T Significant changes in inflation, interest rates and power prices could increase the Group’s near term cost base. Mitigation The macroeconomic volatility has eased during the year with power prices and inflation softening. With ongoing global conflicts the potential remains for this position to change. The Group maintains a manageable debt maturity profile and diverse funding mix with c. 15% index linked which is continuously monitored. Additionally, asignificant proportion of the Group’s power prices has been hedged for the next 12 months in line with defined levels. The Group’s in-house procurement function drives value within strategic contracts and consumables through competitive sourcing and tendering processes. Long-term protection from an increasing inflationary environment is provided through regulatory mechanisms with inflation linked revenues and RCV growth, along with regulatory true-ups. Appetite The Group seeks to de-risk volatility by having set proportions of inflation linked debt, fixed interest, and power prices. These are implemented over time to avoid concentrated exposure to one particular cycle of the macroeconomic environment. The macroeconomic environment sets the financial background for performance and 5 yearly regulatory reviews provide a natural long-term mitigation. Net risk/ Direction of travel Operating Performance Principal risk H Failure to secure, treat and supply clean drinking water Strategic impact Strategic priorities 1 Climate change influence T P Nature related influence T P An inability to secure, produce or supply clean drinking water could result in financial penalties, regulatory enforcement and damage to the Group’s reputation. Mitigation The Group continues to diversify its water resource capacity and the resilience of our network and assets, informed by key plans including Water Resources Management Plan and drought plans. As a result of this investment and higher rainfall no water restrictions are anticipated for 2024. Furthermore, delivery of phase 1 of the desalination project is expected during 2024/25, enabling more time to develop the application for a larger desalination plant. During the year we have extended our ‘Quality First’ continuous improvement culture and training programme to our Bristol colleagues. Asset health is managed through a well-established programme of routine planned and preventative maintenance works with asset and network performance managed by the 24/7 Control Centre. Where such events do occur, these are managed through established incident management procedures and utilises the Group’s supply chain partners. Appetite The Group operates a low tolerance for significant operational failure of its water treatment assets or quality of water produced and seeks to mitigate these risks where possible. Net risk/ Direction of travel Principal risk I Failure to improve wastewater performance resulting in environmental commitments not being delivered Strategic impact Strategic priorities 2, 3 Climate change influence T P Nature related influence T P An inability to improve waste wastewater could result in adverse environment impacts, financial penalties, regulatory enforcement and damage to the Group’s reputation. Mitigation Minimising the impact of our activities on the environment remains a strategic priority for the Pennon Board and Executive. The Group continues to make progress in delivering environmental improvements through the WaterFit programme which combines enhanced processes, targeted capital investment and proactive asset maintenance. Robust governance structures also ensure there is regular reporting on pollution, storm overflow and numeric compliance activities. Despite this progress the significant increase in rainfall and named storms during the second half of the year have increased wastewater flows and impacted headline performance for pollutions and use of storm overflows. Appetite The Group operates a low tolerance for significant operational failure of its wastewater processes and assets and maintains the highest level of environmental standards.

Mitigation The Group continues to enhance and invest in its customer services teams, expanding the channels by which it can interact with and support house-hold and business customers. The Group offers a range of schemes and tariffs to support customers with affordability challenges. Additionally, from April 2024 the Smart Saver tariff trialoffers customers water rates reflecting their level of consumption. During the year both South West and Bristol Water successfully achieved kitemark certification to the vulnerable customer ISO22458 standard. The Group also undertakes a range of initiatives to engage with the wider communities it serves including community road-show events, Neighbourhood Fund and funding to support water retention and leakage reduction. Whilst Bristol Water’s regulatory customer service metric was positive, further improvement is required for South West Water. Both Pennon Water Services and Water2Business continue to maintain high customer satisfaction scores, with ratings 4.8 and 4.9 out of 5 respectively on Trustpilot.

We need the right people in the right places to innovate, share best practice, deliver synergies and move the Group forward. Mitigation The demands for high quality skills and expertise across the Group remains high, which mirrors the national and regional skills demands for our industry. The Group’s People strategy, aligned to the new Group Values, enables the Group to attract, retain and develop our employees as well as recognising the significant contribution that our people make in delivering for our customers and communities every day. The key areas of focus during the year have been on supporting our customers and colleagues during the cost-of-living crisis, reallocating resources to align with customer and business priorities and building capacity to manage a growing capital programme. We regularly engage with our employees, both individually and in groups across multiple communication methods, to really understand their issues, concerns and obtain feedback. We undertake employee pulse surveys throughout the year, conduct Big Chat’s for all employees to hear from our Executive most weeks, have an Employee Engagement Forum attended by functional representatives, provide employee newsletters sharing topical updates and have an employee collaboration platform via Viva Engage. These are all in addition to the countless team meeting, breakfast meetings and toolbox talks which take place every day across the company, to share updates and gather employee feedback. We have continued to develop a diverse and inclusive talent pipeline and have doubled our long-term commitments with enhanced recruitment targets for graduates and apprentices through to 2030 and continued prioritisation of our diversity and inclusion agenda. The Group continues to invest in leadership development with two leadership programmes rolled out across the business helping current and prospective senior leaders develop key skills and mindsets. Appetite We ensure the appropriate skills, knowledge and experience are in place, which combined with our Reward Strategy and robust succession plans provide adequate resilience to keep employee turnover at a minimum.

Mitigation Delivery of the investment included within South West Water’s PR24 business plan will require a significant increase in the Group’s capital programme. The integrated delivery model for K8 will enable greater flexibility and broadens the number of supply chain partners providing enhanced resilience for the Group. The framework procurement for professional services and Tier 1 contractors has been completed and is well progressed for Tier 2. The Group also regularly monitors the financial health of key partners and we work in partnership with our supply chain to identify and manage potential issues and challenges. Where action is required there are established plans andalternative arrangements which provide mitigation and early intervention.

This could have a detrimental impact on our customers and result in financial penalties and reputational damage to the Group. Mitigation External threats are increasing in complexity and sophistication with the National Cyber Security Centre (NCSC) highlighting the heightened risk tocritical national infrastructure and an increased focus on the water sector. The Group maintains a dedicated Information Security team with a strong preventive and detective information security framework, aligned to guidance issued by the NCSC supported by regular training, communications and awareness to staff. South West Water continues to hold the ISO27001 accreditation. Enhanced technical controls introduced during the year across the Group’s corporate and operational technology sector are informed by best practice and learnings from across sectors. Furthermore, the regulated water business continues to progress actions as part of the roadmap to meet the requirements of the Network and Information Systems Directive (NIS), with activities aligned to the priorities identified by the Drinking Water Inspectorate. The Group also maintains established disaster recovery plans which are subject to regular review and testing.

Mitigation The Group has a senior project team with experience of the regulatory approvals process following the acquisitions of Bournemouth Water and, most recently, Bristol Water. The CMA have confirmed that it will refer the transaction for a Phase 2 review unless acceptable undertakings are offered. Pennon intends to offer appropriate undertakings and, in line with the CMA’s guidance, the CMA will then consider whether to provisionally accept the proposed undertakings. Should those undertakings be provisionally accepted, in line with standard procedure, the CMA would then launch a consultation on those proposals. Robust controls have been implemented to ensure the Group is fully compliant with all CMA requirements during the process. Appetite Opportunities that support the Group’s strategic priorities are assessed against an expected level of return adopting clearly defined factors and metrics. Net risk/ Direction of travel Our risk management continued 64 Annual Report and Accounts 2024 « Pennon Group plc The Board’s consideration of the longer-term viability of the Group is an extension of the Group’s strategic business planning, which is managed through regular long-term modelling and monitoring of key measures including gearing, debt covenant headroom and level of liquidity. The resilience of the business and these key viability measures are appropriately assessed by a number of mechanisms including a robust risk management assessment, sensitivity analysis and stress tests of financial performance. The overall market context is a cornerstone of the viability assessment. The Group’s main operating subsidiary of South West Water now accounts for the vast majority of the Group’s earnings, being a long-term business characterised by multi-year investment programmes, with associated revenue streams with high levels of future visibility. The viability assessment has been made with reference to the Group’s current position and prospects, including consideration of the ongoing impacts of the Ukraine crisis, climate change, its longer-term strategy, the Board’s risk appetite and the Group’s principal risks and how these are managed, as detailed on pages 55 to 64 of the Risk report. Period of assessment The Board regularly considers the appropriate period for the viability assessment to be performed in line with the UK Corporate Governance Code. The Board considers the appropriate period to assess the Group’s viability remains unchanged at five years, which recognises both the longer-term visibility in the regulatory environment of the South West Water business and the corporate activity, including acquisitions and other non-regulated investments, undertaken by Pennon. Risks The Board considers the preventative and risk management actions in place and the potential impact of the principal risks (as detailed on pages 55 to 64) against our ability to deliver the business plan. This assessment has considered the potential impact of these and other risks arising on the business model, future performance, solvency and liquidity over the period in question. The Group has a strong liquidity and funding position with £601.4 million of cash and committed facilities as at 31 st March 2024 and netassets of £1,162.6 million. The Group has a mixture of fixed, floating and index-linked debt financing with a weighted average maturity of non-current debt, excluding leases, being 12 years. In making their assessment, the Directors reviewed the principal risks and considered which risks might threaten the Group’s viability. Over the course of the year the Board, either directly or through the activities of the Audit Committee, has considered a deep-dive review of the following principal risks to enable a thorough assessment of the impact ofthese risks on ongoing viability: • Engineering supply chain resilience. • Water quality. • Cyber security. Stress testing The Group’s business plan has been stress-tested. Whilst the Group’s risk management processes seek to mitigate the impact of principal risks as set out on pages 55 to 64, individual sensitivities (shown in the table below) have been identified. These sensitivities, which are ascribed a value with reference to risk weighting, factoring in the likelihood of occurrence and financial impact, were applied to the baseline financial forecast which uses the Group’s annual budget for FY 2024/25 and longer-term strategic business plan through to March 2029. The impact of climate risks have been assessed in detail as set out in the Task Force on Climate-related Financial Disclosures (TCFD) section on pages 78 to 109. The Group’s strategic business plan includes the expected investment identified at this stage to meet climate-change adaptation. Thestress-testing scenarios applied during the viability assessment period do not include specific reference to climate-change related risks alone as climate change has been considered as part of the principal risks identified. Beyond the period of assessment, additional impacts from climate change are considered in more detail within the TCFD section along with mitigatingactions. Viability statement The Directors of Pennon Group plc are responsible for ensuring thelong-term viability of the Group. The Directors need to ensure the resilience of the Company by identifying, managing, avoiding or mitigating risks which may impact viability. Principal risk Viability sensitivities tested A: Changes in Government policy Changes in Government policy affecting the water industry, such as additional environmental legislation, may impact operational performance or investment requirements. The estimated average adverse impact on the Group’s cash flows from a range of potential policy changes has been applied as a sensitivity. B: Changes in regulatory frameworks and requirements Potential changes in the PR24 price review may impact allowed regulatory returns in the Water segment. The estimated average adverse impact on the Group’s cash flows from a range of potential policy or determination changes has been applied as a sensitivity. C: Non-compliance with laws and regulations The estimated impact of financial penalties and reputational damage from failure to comply with laws and regulations has been modelled as a sensitivity. D: Inability to secure sufficient finance and funding, within our debt covenants, to meet ongoing commitments The impact of reduced availability of financing resulting in increased costs has been modelled asasensitivity. E: Non-compliance or occurrence of an avoidable health and safety event The financial impact and cash outflows related to a major health and safety event has been applied as a sensitivity. F: Failure to pay all pension obligations as they fall due and increased costs for the Group should the defined benefit pension scheme deficit increase The financial impact on the Group’s gearing from additional funding being required to support theGroup’s defined benefit pension schemes has been applied as an adverse scenario. 65Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Principal risk Viability sensitivities tested G: Macroeconomic near-term risks impacting on inflation, interest rates and power prices The adverse impacts of higher operating and finance costs from increasing power prices and general inflation increases over and above increases assumed in base financial plans, including the impact on Totex underperformance on regulatory returns and impact on debt financing costs have been applied as a sensitivity, as well as a reduction in the collection of customer debt from adverse economic conditions. H: Failure to secure, treat and supply clean drinking water The adverse impacts from non-delivery of regulatory performance targets which result in ODI penalties, other financial penalties and required additional investment reducing Group revenues andcash inflows have been applied as a sensitivity to the base plan. I: Failure to improve wastewater performance results inenvironmental commitments not being delivered J: Failure to provide excellent service or meet the needs and expectations of our customers and communities K: Difficulty in recruiting and retaining staff with the skills required to deliver the Group’s strategy L: Insufficient capacity and resilience of the supply chain to support the delivery of the Group’s operational and capital programmes which more than doubles inAMP8. M: Inadequate technological control or cyber attack results in a breach of the Group's assets, systems anddata The adverse financial impacts of a cyber attack resulting in operational disruption, potential loss ofdata, potential detrimental impacts on customers with potential for financial penalties have been included in the sensitivity analysis. N: Failure to receive CMA approval for the acquisition of Sutton and East Surrey Water (SES Water) The costs associated with failing to receive CMA approval for the acquisition of SES Water have been modelled in a downside scenario. A combined stress-testing scenario has been performed to assess the overall impact of these individual scenarios impacting the Group collectively. Thecombined weighted impact of the risks occurring is c.£80 million: this value is considered equivalent to an extreme one-off event that could occur within ayear, though the probability of such an event happening is deemed unlikely. Stress-testing evaluation and mitigations Through this testing, it has been determined that none of the individual principal risks would in isolation, or in aggregate, compromise the Group’s viability over the five-year period. The assessment has been conducted by reviewing the impact on the solvency position as well as debt and interest covenants. The financial impacts of the risks were probability weighted to obtain a value that was used in the stress testing. While mitigations were not required in any of the above individual or combined scenarios to ensure that the Group was viable, additional mitigations could be deployed to reduce gearing and increase covenant headroom. These include: • Reduction in discretionary operational expenditure. • Deferral of capital expenditure and/or cancellation of non-essential capital expenditure. • Reduction in the amount of dividend payable. • Raising additional funding. The Group has confidence in its ability to raise additional funding should it be required to ensure the Group maintains solvency. In addition, a reverse-engineered scenario that could possibly compromise the Group’s viability over the five-year assessment period has been modelled. This scenario builds on the factors above and additionally assumes all the Group’s principal risks incurring in any given year across the viability period, with no probability weightings attached. The Board considered the likelihood of this scenario on the Group’s viability over the five-year viability period as remote, concluding the Group could remain viable. Mitigations, as noted above, could also be deployed over the period if deemed necessary. In making its assessment of the Group’s viability, the Directors have taken account of the Group’s strong capital solvency position, the Group’s latest assessments of forward power and other commodity prices, latest inflation forecasts, its ability to raise new finance and a key potential mitigating action of restricting any non-contractual payments. In assessing the prospects of the Group, the Directors note that, as the Group operates in a regulated industry which potentially can be subject to non-market influences, such assessment is subject to uncertainty, the level of which depends on the proximity of the time horizon. Accordingly, the future outcomes cannot be guaranteed or predicted with certainty. As set out in the Audit Committee’s report on pages 136 to 141, the Directors reviewed and discussed the process undertaken by management, and also reviewed the results of the stress testing performed. Viability assessment conclusion The Board has assessed the Group’s financial viability and confirms that it has a reasonable expectation that the Group will be able to continue in operation and meet its liabilities as they fall due over a five-year period, the period considered to be appropriate by the Board in connection with the UK Corporate Governance Code.

During 2023/24 we have committed to even more ambitious targets, to go beyond reducing our operational emissions, and set out scope 1, 2 and 3 GHG emission reduction targets, targets to reduce emissions across our value chain, and to increaseour use of renewable electricity. Pillar Our three-pillar strategy remains unchanged Progress against our three-pillar strategy 1 Sustainable living • Reducing emissions through changes to operational practices, increasing energy efficiency, and switching to lower carbon fuel sources. • Meeting our commitments to reduce leaks and help customers to use less water – protecting the environment and saving carbon. • In 2023/24 our wastewater back-up generators have been switched from using diesel fossil-fuel to using lower carbon HVO (Hydrotreated Vegetable Oil) made from waste oil. • We are continuing with our programme of pump efficiency testing, pump repair and replacement. We have installed two new pumps at our Roadford Dam site, one low lift pump at Restormel water treatment works in Cornwall as well as one at Longham water treatment works in our Bournemouth region. We have proactively developed a new plan to refurbish our activated sludge processes on our wastewater treatment works as well as plans to replace some of our largest blowers providing air to those processes. We have also conducted site-based energy audits on our Bristol Water sites as part of compliance with Phase 3 of the Government’s Energy Savings Opportunities Scheme (ESOS). • We have embarked on a nitrous oxide (N2O) emissions monitoring trial at our Countess Wear (Exeter) wastewater treatment works, as well as a separate trial to measure fugitive emissions ofmethane (CH4) emissions at the same site. • Our transition to electric vehicles continues with over 50 electric vehicles now on our fleet ofvans and cars. Whilst the most of our transport fleet is still petrol or diesel fuelled, we plan togradually transition to a 100% electric vehicle fleet during the next decade. 2 Championing renewables • Maximising self-generation from renewables at our sites across the South West – working with partnerships and utilising our expertise. • Where we cannot generate enough electricity to meet all our needs ourselves, 100% of what we purchase will be from renewable sources. • South West Water continues to source 100% renewable electricity (since 2022). We will negotiate to switch Bristol Water to 100% renewable electricity at the appropriate contract renewal time. • Onsite renewables with third parties are a mix of CHP, hydro, solar and wind. SWW has achieved 9.1% and Bristol 1.1% on-site renewable energy generation. • We have completed a feasibility study for the installation of floating solar PV arrays at a number of our reservoirs and are progressing to the next stages at one of our large drinking water sites. • We have made a significant advance in sourcing off-site renewables through the third party owned Rexon Cross 500kW wind turbine, which is now feeding renewable electricity into our Roadford Reservoir site through a private wire. The turbine has the potential to generate 1.5GWh of energy each year which is approximately 15% of the total energy used on the site. 3 Reversing carbon emissions • Reversing carbon emissions from our core activities. • Working in partnership to ensure our core activities reverse carbon emissions through solutions such as peatland restoration. • Supporting the development of innovative solutions to develop low carbon footprint processes through research and development. • Our catchment management programmes include improved soil management, wetland creation, buffer strips, tree planting and other nature-based solutions. We have pioneered a collaborative partnership approach to peatland restoration across the region, continuing to develop best practice and build capacity to scale up into the future. Over time these interventions store more carbon in the landscape and reduce loss to the atmosphere, whilst retaining water upstream to improve long-term resilience. • In 2023-24 we have planted 80,327 trees to exceed our annual target of 50,000 trees and restored 493 hectares of peatland towards a total of 1,558 hectares restored so far throughout AMP7. Once completed our peatland restoration programme planned for AMP7 is expected to sequester around 650,000 tCO 2 e over the next 50 years. Meanwhile the 253,000 trees nowplanted (AMP7 delivery) are expected to store an estimated 17,700 tCO 2 e during the next 30years. • Looking forward, we have included a range of nature-based solutions in the PR24 Business Plansubmission (2025-2030) to increase opportunities to lock up carbon through our activities. Wecontinue to collaborate across the water industry to investigate other land and marine- based carbon sequestration opportunities, such as seagrass restoration and development ofasoil carbon code. 69Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Science Based Targets As a Group we have committed to near-term Science Based Targets (SBTs). Our targets were validated and approved by the Science Based Targets Initiative in May 2024 and we will now focus on delivering our targets. SBTs provide a clearly defined pathway for companies to reduce greenhouse gas emissions. Targets are considered ‘science-based’ ifthey are in line with what the latest climate science deems necessary to meet the goals oftheParis Agreement – limiting global warming to 1.5°C above pre- industrial levels. Our SBTs, presented below, support our water and wastewater greenhouse gas, and embodied carbon bespoke performance commitments. The Group commits to reduce absolute scope 1 and scope 2 GHG emissions 68% by 2032/33 from a 2021/22 base year. The Group commits to reduce absolute Scope 3 GHG emissions from 'well to tank' electricity and fuels, the delivery of electricity, emissions from waste, and business travel and commuting, by 30% over the same timeframe. The Group commits that 60% of its suppliers by emissions covering purchased goods and services, capital goods and upstream transportation and distribution will have science-based targets by FY2027/28. The Group commits to increase annual sourcing of renewable electricity to100% by 2030. Further details of how we are integrating climate into our business and readying for a low carbon future can be found in our TCFD report on pages 78 to 109. GHG emissions performance In line with good practice and to reflect the outcome of our 2021/22 materiality assessment, we set new interim Net Zero targets in 2022. Our 2023/24 performance is presented below. Net Zero target 2023/24 Performance 2023/24 Target 2025 Target 2030 Target % Energy usage from renewable generation 7.5% 8% 13% 50% Reducing GHG emissions (%) 71.9% 68% 70% 100% These figures have been externally assured by DNV. * Scope 2 market-based emissions only. GHG emissions Scope 2 market-based GHG emissions have reduced from 91,330 tCO 2 e (restated figure due to fuel mix disclosure correction) to 25,662 tCO 2 e this year from our 2020/21 baseline equating to a 71.9% reduction. Overall GHG emissions against our Net Zero 2030 emission boundary for Scope 1, Scope 2 and selected Scope 3 operational emissions within the boundary of the regulated businesses have decreased by c.45.2%. Full details of our 2023/24 GHG emissions are provided in our SECR report from page 71. Embodied carbon Our carbon emissions extend beyond our daily operations. Embodied carbon are emissions associated with the construction, repair, and maintenance of our physical assets, and we are cognisant that they can account for up to one-third of the water sectors total emissions. We are committed to reducing all sources of our carbon emissions, which is why we have developed a bespoke performance commitment to support our embodied carbon goals. Embodied carbon accounting is the foundation of decarbonising our capital projects and our supply chain, and we are working collaboratively with our supply chain to identify the best technologies for embodied carbon accounting, and strategies to drive down our emissions. Net Zero culture We recognise that achieving our Net Zero goals will be a collaborative effort. We are working towards creating a working environment in which workers, customers, and suppliers are motivated to hasten our transition to Net Zero emissions. We have developed a robust communication and engagement plan, supported by an effective governance structure working with internal stakeholders at all levels to ensure carbon emissions and our net zero commitments are adequately considered in decision making. This is further corroborated by data, and our benefits realisation work, where we quantify and monitor the greenhouse gas consequences of our Net Zero initiatives. Our bespoke approach will ensure an enduring Net Zero culture. Renewable energy We remain committed to our target of 50% of energy generation from a mix of renewable energy sources including onsite Solar PV, floating Solar PV, grid connected Solar PV, wind power, hydroelectricity and making more use of our bioresources for generating energy. We have achieved 7.5 % energy from renewable sources across the group in2023/24. This performance is despite below average solar radiation last year and an enhanced maintenance regime across all our assets. In addition, we have continued delivery of our latest on-site solar and connection of a wind turbine to Roadford treatment works via a private wire arrangement. Overall, our installed renewable energy capacity now totals 18.5MW including connected private wire assets. Process and fugitive emissions Process and fugitive emissions, mainly in the form of methane (CH4) and nitrous oxide (N2O), arise from our wastewater treatment processes. Worldwide there is difficulty in measuring process emissions, this mean that it is difficult to establish a baseline and monitor changes in N2O emissions. Measuring and monitoring is the first step; without it, we cannot establish the efficacy of N2O reduction initiatives. We are piloting a N2O monitoring technology at one of our wastewater treatment sites, Countess Wear. This pioneering initiative, where the treatment facility has recently been cleaned, will benchmark ‘low’ N2O emissions under various scenarios, and allow us to assess seasonal variability in N2O emissions over the course of the year. We have also commenced with a separate trial to directly measure fugitive emissions of methane (CH4) at the same site. Findings from these trials will inform effective process emission reduction strategies in the future. Transition plan Through our established strategies, plans and policies, we are preparing for a changing climate and lower carbon economy. Our annual TCFD response on pages 78 to 109 sets out further details of this in accordance with the TCFD recommendations. This identifies one of our key transition risks as rising energy costs. Through our planned investment in renewable energy alongside our dynamic hedging strategy we are managing this risk. We are aware of the work of the newly established Transition Plan Taskforce (TPT) to develop a ‘gold standard’ framework for transition plans. We are considering the TPT’s guidance and will look to publish our Group Transition Plan in due course. For further information on nature-related disclosures, please see our Taskforce on Nature-related Financial Disclosures on pages 78 to 109.

Change in GHG emissions Operational Scope 1 and 2 emissions (market-based) decreased by 12.8% from 2022/23, largely as a result of a reduction in the need for additional water pumping in 2023/24 as the weather was much wetter than 2022/23, this also coincided with a reduction in the use of diesel fuel for pumping and stand-by generation, as well as a reduction in the emissions factor applied toour Bristol Water grid electricity consumption. The revenue-based intensity metric has continued to reduce for the Group and the 'market- based' value now stands at 6tCO 2 e/£100,000 turnover compared to a value of 7.3 tCO 2 e/£100,000 in the previous year, continuing the trajectory ofemissions reductions relative to revenue earned. Scope 3 GHG emissions Scope 3 categories were evaluated for relevant categories in line with the reporting guidance. The assessment, carried out by carbon consultants Eco Act on behalf of Pennon, is based on 2023/24 activity data for the Group. The estimated Scope 3 GHG emissions for 2023/24 for the Group are 314,999 tCO 2 e compared to the equivalent figure in 2022/23 of 239,653 tCO 2 e (Restated to correctly account for waste generated in operations). Bristol Water’s Scope 3 activities have been calculated and reported within the Group figures for the first time. The change in reported emissions is due to better interrogation of the spend data used to drive Category 1 purchased goods and services calculation. This analysis showed that some financial spend lines were wholly down to financial transactions with zero emissions associated and therefore these activities were excluded from 2023/24 calculations. A breakdown of our estimated Scope 3 GHG emissions is provided in our ESG Databook, published on our website (www.pennon-group.co.uk/ sustainability). GHG Reporting Methodology Our approach follows the UK Government’s Environmental Reporting Guidelines, including Streamlined Energy and Carbon Reporting guidance (2019) and the Greenhouse Gas Protocol Corporate Standard including the Scope 3 Calculation Guidance (collectively referred to here as the reporting guidelines). In calculating our emissions, we have used the 2023 UKGovernment conversion factors for GHG reporting. Organisational boundary and scopes The GHG emissions listed here cover 100% of the Group’s companies, each of which uses the financial control approach, except equity share for Bristol Water Holdings Companies, to report GHG emissions. We report our Scope 1, 2 and 3 GHG emissions where relevant. A breakdown of Scope 3 GHG emissions categories is provided in our supplementary ESG Databook online at www.pennon-group.co.uk/sustainability. Market and location-based methodology We report both market-based and location-based Scope 2 GHG emissions. Where our supply is backed by Renewable Energy Guarantees of Origin (REGOs), this qualifies as zero carbon market-based emissions. Where supply is not REGO backed, in accordance with the reporting guidelines, wehave used our electricity suppliers’ specific published Fuel Mix Disclosure emissions factors to report our Scope 2 market-based emissions. Where FuelMix Disclosure emissions factors are not available, we have used theresidual grid mix emissions factor. Self-generated renewable energy export In accordance with the reporting guidelines, we may report an emissions reduction in our reported net CO 2 e figure for any renewable electricity wehave generated and exported to the national grid or a third party. External assurance statement Group Scope 1 and 2 GHG emissions and energy use, together with selected Scope 3 GHG emissions, have been independently assured by DNV. The assumptions, methods and procedures that are followed in the development of the reported data have been tested and the data audited for accuracy and consistency. Assurance statements can be found at www.pennon-group. co.uk/sustainability. Offshore Emissions All of Pennon Group’s energy usage is within the UK and Pennon Group hadno offshore GHG emissions or energy usage in the reporting period. Energy usage Including self-supplied energy, the Group used 484,374 MWh of energy in 2023/24, compared to 485,823 MWh in 2022/23.

Energy efficiency action taken Our energy efficiency interventions during 2023/24 are estimated to have avoided around c.6.5 GWh of additional energy use, or around 1.4% of our total energy consumption (excluding transport). We have taken further steps this year to focus on testing, repairing or replacing our largest rotating operational assets. These actions were prioritised based on the resilience offered to sites, as well as for optimising our energy consumption. We have been modernising ourrotating assets, including the deployment of more efficient aeration equipment in the form of new blowers (air compressors), and we have also embarked on a programme of optimising our Ultra-Violet treatment infrastructure, including making sure the calibration of the equipment controlling is carefully set up todeliver the most efficient usage. 73Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information 73Pennon Group plc » Annual Report and Accounts 2024 Sustainability reporting continued SASB Pennon 2023/24 disclosure For the third year, we have aligned our non-financial disclosures tothe Sustainability Accounting Standards Board (SASB) reporting framework.

We are committed to meeting the challenges arising as a result of climate change, the nature emergency, and the transition to Net Zero. Our regulated water business is the main focus of our TCFD & TNFD disclosures, with the majority of our assets, revenues, and expenditures related to this area of our business. TCFD recommendations Created by the Financial Stability Board (FSB), the TCFD published its recommendations in June 2017. This is our fifth year of TCFD reporting and the below shows our progress and compliance with the recommendations including the updated TCFD guidance (2021 Annex). In alignment with FCA listing rule 9.8.6R(8) we have taken into account available knowledge and guidance concerning the listing rule and climate-related risks to develop our compliant TCFD disclosure. Each year our disclosures have been enhanced as knowledge and guidance improves. Pennon has addressed the 11 recommended disclosures and has considered the latest best practice guidance from the TCFD. As part of our ongoing TCFD programme, we have continued to enhance our assessment of physical risks, transition risks, and climate-related opportunities. TNFD recommendations The TNFD published its final framework for nature-related financial disclosures in September 2023. This is our third year of voluntarily reporting against the TNFD framework. This year we are taking the opportunity to integrate TNFD into our TCFD disclosures, recognising the substantial overlap and synergies for our business between action on climate change and the nature emergency. At the same time, we also recognise some trade- offs in meeting our goals around resilience, Net Zero, and nature. We acknowledge there is further work to do on the recommended TNFD disclosures, and we are continuing to monitor the inclusion on nature-risks inthe UK sustainability disclosure requirements. Developments in 2023/2024 2023 was another year of record-breaking weather with higher than average rainfall rates and frequent storms bringing extreme rainfall and winds. This has presented operational challenges to overcome and although we have ensured the safe and secure supply of water and wastewater services in the region, it further highlights the need for climate change resilience and preparedness. These events have provided us with significant insight into our resilience to these kinds of events (which we may see more frequently in the future), which are factored into our update of our physical climate risk assessment and our review of adaptive strategies. In addition to our published Water Resources Management Plan (WRMP24) and Drainage & Wastewater Management Plan (DWMP), South West Water developed its £2.8 billion business plan proposal (2025-2030) for PR24, focusing on water quality and resilience, storm overflows and pollution, net zero and environmental gains, and addressing customer affordability. Therefore, our TCFD disclosure reflects updated current and future actions to mitigate risks and realise opportunities. The updates to our climate risk assessments also consider new climate-related evidence and recent publications from the Intergovernmental Panel on Climate Change (IPCC) and Climate Change Committee (CCC), further to recent publications from Ofwat (our economic regulator) on scenario analysis, adaptive planning, PR24 methodology, and updates in regulation and legislation, the latter of which gives us greater confidence in our transition risk impact reporting in the short term. Our Company has continued to grow over the past year, with Pennon Power acquiring four new renewable energy generation projects to accelerate our transition to Net Zero, and the acquisition of SES Water. Through Pennon Power we are realising some of the benefits described in our opportunities, whilst in our view SES Water’s material climate risks and opportunities will be similar to the SWW water business risks. We are taking the opportunity to further our resilience this year as we update our Climate Adaptation Report as part of the UK government’s adaptation reporting cycle to feed into the next UK Climate Change Risk Assessment. We are focused on delivering for our stakeholders including our customers and shareholders. As a result, we are continuing to embed climate change resilience, sustainability, and nature-positive practices into decision making within our business, as well as managing the near-term inflationary pressures including power prices. We will also continue to manage changes to our investments to explore new technology, materials, and nature-based solutions, within the current global constraints on capacity and supply chains to deliver both affordability and fairness for our customers. As a Group, we maintain consistent and strong reporting with the CDP, presenting our efforts to combat climate change and our GHG emissions since 2013. Our GHG emissions performance continues to improve, reported through our CDP Climate Change submission in which we received a B in 2023 for both climate change and water security. You can read about our GHG emissions performance on page 71.

These have been identified by considering the climate scenarios described on page 102. Therisks have been assessed using the Pennon 4x4 risk assessment matrix which puts the highest risks in the red category under the RAG rating. Further information on our risk assessment methodology can be found on page 55. We have identified impacts over short (0-10 years), medium (10-30years) and long term (30-100 years) horizons (the rationale behind these time horizons is presented on page 102). Due to the nature of our business, the opportunities are not only assessed ontheir ability to increase our revenues; some are opportunities to save costs and/or carbon, which supports our ability to provide the best outcomes for our customers and stakeholders. We then present our findings from scenario analysis, exploring the potential range of impacts and our strategic responses under plausible contrasting climate scenarios (see page 103). 81Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Physical climate risks Key impacts identified on our operations and customers Examples of our actions to mitigate risks and realise opportunities Primary financial and reputational impacts to our business Key physical climaterisks Increasing frequency and intensity of droughts - risks to water supply, wastewater networks, andservices.

Could lead to reductions in our future abstraction allowances and increased need to release more water to rivers/the environment (see also ‘Climate-related regulation in the Water sector’ transition risk). • Lower groundwater levels reduce borehole yields. Intake, borehole pump and reservoir draw-off levels may not match reduced levels. • Water companies are legally expected to protect, restore and enhance the environment, which includes ensuring sustainable abstraction practices to leave enough water for the environment. This becomes more challenging during droughts. • Saline intrusion due to lowering groundwater compounded by sea level rise (see ‘Rising sea levels’ risk). • Decreased quality of raw water (see ‘gradual and significant increasing average and high temperatures - risks to water quality and water treatment’). • Impacts on wastewater networks due to low flows from surface water. • Low water levels lead to increased incidences of invasive non-native species (INNS) as they are de-stressed and seek new habitats.

Current risk rating Last year’s risk rating Risk of challenges balancing trade-offs in regulation in the Water sector between agendas of Net Zero, climate resilience, environmental enhancement, and other objectives, posing the risk of increasing costs and carbon: Potential undesired climate outcomes due to trade-offs in regulatory priorities. Challenges with balancing objectives to improve environmental outcomes while reducing carbon emissions at the same time as rapid changes in climate-related policies and regulations are occurring in the Water sector. A holistic and balanced approach to delivering our goals for Net Zero, providing a resilient water supply and protecting and enhancing the environment, could be at risk if one agenda imposes more stringent regulation, thus presenting a misalignment in the pace with which preferably holistic actions can be delivered relative to actions that benefit a single more stringent agenda. In some cases, new/enhanced policies and regulations pose a risk due to increasing costs to Pennon or increasing Pennon’s carbon footprint, in other cases the absence of policies and regulation pose arisk due to potential that costs incurred by Pennon may not be recovered through the regulatorysystem. Some examples include: • More stringent environmental regulation being imposed in response to the climate adaptation and nature positive agenda, including the pace with which requirements are being imposed. • Reduced abstraction allowances and increased compensation flows into our rivers being imposed (see our ‘drought’ physical risk). • Increased environmental ambition by other stakeholders to replace lost coastal habitat and manage coastal erosion (see our ‘rising sea levels’ physical risk). • Changes to carbon accounting methodologies and scope boundaries, including switch to location-based GHG accounting methodology instead of market-based accounting (e.g. disincentivising power purchase agreements (PPAs) for renewable energy). • Use of modular desalination to ensure drought resilience at pace, but leading to increased energy consumption. • Enhanced requirements which increase Pennon’s energy and carbon footprint e.g. phosphorus removal, UV disinfection, reducing combined sewer overflows in cases where the scale and pace required disadvantages nature-based solutions. • Regulation in contradiction to achieve overall Net Zero goals, and regulatory system providing limited incentives for wider Net Zero action outside of the regulated water business. Balancing trade-offs from actions to address different agendas in policy and regulation: Current actions: • Horizon scanning to identify emerging/changing regulation. • Stakeholder engagement/public relations management. • Net Zero programme. • Engaging with regulators to explain the climate change impacts of new regulation. • Working with others in the sector to clarify carbon accounting approaches. • Widely engaged with around 200,000 customers and stakeholders over the past two years in developing PR24 business plan. These engagement activities will continue across theregion. • Working with our WaterShare+ Customer Advisory Panel gives us an opportunity to continuously engage our customers and share our work on sustainability and resilience. • Adaptive planning approach within WRMP24 and DWMP23, including high, moderate, andlow environmental ambition. • Considering options which Pennon can take outside of the regulatory framework (e.g.offsite investment in renewable energy). • Ofwat innovation fund being explored to provide additional investment to support Pennon’s ambitious objectives. • Establishment of the Centre for Resilience in Environment, Water and Waste (CREWW) tocollaborate with academia and tackle challenges facing water sector. Future actions: • Pursuing opportunities through our Upstream Thinking programme which includes nature-recovery programmes across our region and other nature-based solutions where these are acceptable under the regulation. • Investment in innovation/ research and development, and investment in enhancements toresilience to key climate risks. • Considering applying an internal carbon price to consider full costs and benefits ofdecisions. • Public value assessments in decision-making (balancing trade-offs of different agendas, and contradictions in the regulatory framework). • Seeking opportunities for additional funding, making the investment case based on corewater company activities. • Future climate adaptation planning and transition planning. Impacts from mitigating the risk: We could incur increased expenditure (Capex and Opex) due to changes to regulation, for example costs related to installation and operation of new process equipment to meet enhanced regulations. Some of these costs could be recoverable through the regulatory system. Increased energy and material use to meet increased regulatory requirements has potential to increase our footprint through operational andembodied carbon. Impacts of the unmitigated risk: If we fail to balance regulatory requirements, we could face reduced ODI rewards/ increased ODI penalties (affecting our revenue). Public perception of how we balance trade-offs could result in negative impacts on our reputation (see our see our ‘Negative public and stakeholder’ relations risk).

Current actions: • Cold weather plan, including prioritisation of support for vulnerable customers. • Investment in centralised control room and alternative water supply teams. • Appointment of a new incident management team. • Improved staff incident training. • Working with other water companies to develop a business continuity and visualisation tool that will support operational decisions and reduce customer impacts, including to the most vulnerable people. • Backup power at plants to manage risks of energy supply interruption. • Programme of generator roll-outs. • Recovery plans for 100 WWTWs. • Working with other stakeholders (e.g. energy providers) to enhance resilience. • Mutual aid agreements to manage competing responses for aid during emergency events. • Strategic water grid to enhance resilience of supply. • Diversified energy supply with our own generation of renewable energy provides additional energy resilience. Planned or future actions: • Extend real-time monitoring and control. • Extend recovery plans at more WWTWs. • Invest in mobile granular activated carbon units. • Further investment in generating renewable energy and back-up power. • Use of drones during drought and high temperature events to identify leaks. • Public value assessments in decision-making (balancing trade-offs of different agendas, and contradictions in the regulatory framework). • Seeking opportunities for additional funding, making the investment case based on core water company activities. • Future climate adaptation planning and transition planning. Impacts from mitigating the risk: We could incur additional expenditure (Opex and Capex) for maintenance and upgrades to assets to enhance resilience to storms. Some of these costs could be recoverable through the regulatory system. Increased energy and material use could impact our operational and embodied carbon. Impacts of the unmitigated risk: Service disruptions could negatively impact our reputation and reduce ODI rewards/increase ODI penalties (affecting our revenue). We could face additional expenditure (Opex and Capex) to restore services and repair assets. Some of our assets could deteriorate and face impairment due to physical impacts. Climate transition risks Key impacts identified on our operations and customers Examples of our actions to mitigate risks and realise opportunities Primary financial and reputational impacts to our business Type as defined by TCFD Policy, Regulation and Legal Risks Relevant time horizon of risk Short and medium term Potential for this risk to decrease over time as regulation evolves to remove contradictions and misalignment, and as leadership on climate action becomes commonplace across Government and the economy. Current risk rating Last year’s risk rating Risk of challenges balancing trade-offs in regulation in the Water sector between agendas of Net Zero, climate resilience, environmental enhancement, and other objectives, posing the risk of increasing costs and carbon: Potential undesired climate outcomes due to trade-offs in regulatory priorities. Challenges with balancing objectives to improve environmental outcomes while reducing carbon emissions at the same time as rapid changes in climate-related policies and regulations are occurring in the Water sector. A holistic and balanced approach to delivering our goals for Net Zero, providing a resilient water supply and protecting and enhancing the environment, could be at risk if one agenda imposes more stringent regulation, thus presenting a misalignment in the pace with which preferably holistic actions can be delivered relative to actions that benefit a single more stringent agenda. In some cases, new/enhanced policies and regulations pose a risk due to increasing costs to Pennon or increasing Pennon’s carbon footprint, in other cases the absence of policies and regulation pose arisk due to potential that costs incurred by Pennon may not be recovered through the regulatorysystem. Some examples include: • More stringent environmental regulation being imposed in response to the climate adaptation and nature positive agenda, including the pace with which requirements are being imposed. • Reduced abstraction allowances and increased compensation flows into our rivers being imposed (see our ‘drought’ physical risk). • Increased environmental ambition by other stakeholders to replace lost coastal habitat and manage coastal erosion (see our ‘rising sea levels’ physical risk). • Changes to carbon accounting methodologies and scope boundaries, including switch to location-based GHG accounting methodology instead of market-based accounting (e.g. disincentivising power purchase agreements (PPAs) for renewable energy). • Use of modular desalination to ensure drought resilience at pace, but leading to increased energy consumption. • Enhanced requirements which increase Pennon’s energy and carbon footprint e.g. phosphorus removal, UV disinfection, reducing combined sewer overflows in cases where the scale and pace required disadvantages nature-based solutions. • Regulation in contradiction to achieve overall Net Zero goals, and regulatory system providing limited incentives for wider Net Zero action outside of the regulated water business. Balancing trade-offs from actions to address different agendas in policy and regulation: Current actions: • Horizon scanning to identify emerging/changing regulation. • Stakeholder engagement/public relations management. • Net Zero programme. • Engaging with regulators to explain the climate change impacts of new regulation. • Working with others in the sector to clarify carbon accounting approaches. • Widely engaged with around 200,000 customers and stakeholders over the past two years in developing PR24 business plan. These engagement activities will continue across theregion. • Working with our WaterShare+ Customer Advisory Panel gives us an opportunity to continuously engage our customers and share our work on sustainability and resilience. • Adaptive planning approach within WRMP24 and DWMP23, including high, moderate, andlow environmental ambition. • Considering options which Pennon can take outside of the regulatory framework (e.g.offsite investment in renewable energy). • Ofwat innovation fund being explored to provide additional investment to support Pennon’s ambitious objectives. • Establishment of the Centre for Resilience in Environment, Water and Waste (CREWW) tocollaborate with academia and tackle challenges facing water sector. Future actions: • Pursuing opportunities through our Upstream Thinking programme which includes nature-recovery programmes across our region and other nature-based solutions where these are acceptable under the regulation. • Investment in innovation/ research and development, and investment in enhancements toresilience to key climate risks. • Considering applying an internal carbon price to consider full costs and benefits ofdecisions. • Public value assessments in decision-making (balancing trade-offs of different agendas, and contradictions in the regulatory framework). • Seeking opportunities for additional funding, making the investment case based on corewater company activities. • Future climate adaptation planning and transition planning. Impacts from mitigating the risk: We could incur increased expenditure (Capex and Opex) due to changes to regulation, for example costs related to installation and operation of new process equipment to meet enhanced regulations. Some of these costs could be recoverable through the regulatory system. Increased energy and material use to meet increased regulatory requirements has potential to increase our footprint through operational andembodied carbon. Impacts of the unmitigated risk: If we fail to balance regulatory requirements, we could face reduced ODI rewards/ increased ODI penalties (affecting our revenue). Public perception of how we balance trade-offs could result in negative impacts on our reputation (see our see our ‘Negative public and stakeholder’ relations risk). Some of our assets could incur obsolescence and impairment if they are driving high carbon emissions or poor environmentaloutcomes. 87Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Climate transition risks continued Key impacts identified on our operations and customers Examples of our actions to mitigate risks and realise opportunities Primary financial and reputational impacts to our business Type as defined by TCFD Policy, Regulation and Legal Risks Relevant time horizon of risk Short and medium term In the short term the risk is more focused on funding to achieve Net Zero, over the medium and long term the risk will increasingly focus on funding to enable adaptation to climate change.

Future actions: • Procurement strategies (e.g. requirements on suppliers to meet ESG criteria/ low climaterisks, reduce emissions). • Learning from other companies in UK and internationally. • Diversifying supply chain to lower emissions/risks. • Sourcing locally, where possible. • Life cycle assessment requirements for suppliers. Type as defined by TCFD Products and Services Relevant time horizon of risk Short, medium, and long term Opportunity in the short, medium, and long term to enhance Pennon’s revenue through delivery of Strategic Water Resource and bioresources schemes. Current opportunity rating Last year’s opportunity rating Not included last year Enhancing revenue through providing resilient water solutions, bioresources, and expertise to other water companies: Opportunities to invest in water resources schemes linked to climate change, bioresources opportunities which align with the transition to Net Zero, and other opportunities to enhance ourrevenues. Some examples include: • Delivering strategic resource options (SROs) and resilient water solutions for other water companies (e.g. modular desalination technology). • Opportunities to sell expertise and technologies for water efficiency and leakage reduction. • Opportunities to sell bioresources (e.g. biogas, nutrients, sludge etc.). • Opportunities to provide/sell expertise in bioresources to other companies. Delivering water resource schemes and bioresources opportunities: Current actions: • Preparatory work on three Strategic Water Resource schemes. • Engagement with other water companies, engagement with regulators and stakeholders. • Business plan includes opportunity related to pyrolysis for bioresources. • Establishing commercial and legal arrangements for SROs and sale of bioresources. • Continued roll-out of new technology in our region. Future actions: • Engagement with customers to build support (e.g. social licence). • Innovation and R&D in collaboration with CREWW Potential to increase our revenue through delivering SROs and selling bioresources and our expertise to peer companies. However, this requires significant investment (Opex and Capex) to enable these opportunities. Some of these costs could be recoverable through the regulatory system. We will need to manage the carbon footprint associated with our SRO and bioresources schemes. 101Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Short-, medium- and long-term horizons In determining our strategy, we have processes in place for identifying, assessing, and responding to climate-related risks and opportunities. In shaping thestrategy, we consider short-, medium-, and long-term horizons. Short-term – 1 to 10 years Over this horizon we define key targets (operational, financial, sustainability) and we consider changing regulatory frameworks and emerging Government policies. We develop business plans every 5 years, defining our actions and investments over this period. Operational risks are planned and budgeted for over this time frame and planning begins during this period for the next regulatory period. Our operational Net Zero 2030 commitment falls within this time horizon, as well as the price review in 2029 (PR29). Transition risks and opportunities are likely to have the largest impacts to our business across this period, with physical risks projected to increase over time. Medium-term – 10 to 30 years Water and wastewater treatment assets have a typical life of up to 30 years and will therefore be reviewed over this horizon. Our WRMP and DWMP strategic plans consider requirements across this period. Major projects and operational plans will be renewed and managed over this time frame to ensure projects meet the correct regulatory period plans. Our 2045 total Net Zero target falls within this horizon, as well as the UK’s 2050 Net Zero target, which will continue to present emerging policy and market challenges. Transition risks and physical risks will both impact our business across this period to varying levels depending on global GHG emissions and the Net Zero pathway taken by the UK and globally. Long-term – 30 to 100 years Typically for longer-term strategic direction, risk, and resilience planning. Investment requirements for our long-life assets are considered such as mains pipes and reservoirs. Over this time period the planet is currently projected to warm by around 3°C; however there is much uncertainty related to the effectiveness of global climate change mitigation. Physical climate risks are likely to have the largest impacts to our business over this time horizon. Climate scenario analysis Scenarios In alignment with the TCFD guidance, we have assessed the risks and opportunities associated with climate change and the transition to a Net Zero climate-resilient economy. We have used plausible contrasting scenarios to explore the potential range of impacts in the future and in turn the possible range in our strategic responses required to mitigate risks and build adaptive capacity in an uncertain future. Our physical risk scenarios are informed by the IPCC’s Representative Concentration Pathways (RCPs) from the IPCC’s 5 th assessment (2014), including a high and a low emissions scenario, which are also used as the basis for planning by Ofwat as part of the PR24 methodology. The IPCC's 6 th Assessment report was released in 2023, and in it the IPCC has adopted new climate scenarios know as Shared Socioeconomic Scenarios (SSPs). However, Pennon has continued to use the RCP scenarios due to these being mandated by Ofwat's PR24 methodology. Our transition scenarios are informed by high and low levels of socio-economic drivers surrounding policy ambition, the speed at which policy is implemented, and the pace of technological advancement. This year we have updated our transition risk assessment to adopt transition scenarios developed by the Network for Greening the Financial System (NGFS). These transition scenarios have become widely adopted in the UK and supersede the previous bespoke transition scenarios we used in the previous years. The two Network for Greening the Financial System (NGFS) transition scenarios we used are: (1) Orderly transition, aligned to the NGFS Net Zero 2050 and (2) Hot house world aligned to the NGFS Current Policies. Also, important to note that the NGFS Net Zero 2050 aligns fairly closely with the IEA Net Zero 2050 scenario. We have selected these contrasting scenarios as they span a range of possible futures, and present different challenges and opportunities for our business. The NGFS Disorderly Transition Scenario has also been considered, but our view is that negative impacts for our company are more significant under the NGFS Current Policies Scenario, so it is this one that has been the focus of our scenario analysis to provide a stress test of our resilience. We will continue to re-visit our scenario analysis in future, including considering the merit of selecting additional scenarios. Our scenarios can be defined as follows: 1. The IPCC’s Representative Concentration Pathways from the IPCC’s 5 th assessment (2014) Key assumptions For our scenario analysis, the following assumptions for all scenarios were made: • Scenarios focus on the UK policy and regulatory context and are semi- independent of global action and temperature pathways. • It is assumed that the current high energy prices remain high throughout this decade. • The Government’s ambition around environmental protection and conservation remains high, regardless of the pace of transition. • No significant change to Pennon Group’s business activities. • Population in our region increases by 0.4 million by 2050, overall water demand remains unchanged from today (due to leakage reduction and water efficiency measures), and overall volume of wastewater treated remains unchanged from today (due to actions taken to reduce surface water flows to sewers). RCP2.6 1 : Lower Physical Impacts An approximate 2°C warming scenario by the year 2100 – corresponding to a low emissions ‘optimistic’ scenario. 1.5 degree scenario: NGFS Net Zero 2050 A scenario which sees the UK as a global leader with strong policies and actions to mitigate climate, aligned with the Paris Agreement. Policy ambition 1.5ºC Government policy Immediate and smooth Technology change Fast change RCP8.5 1 : High Physical Impacts An approximate 4°C warming scenario by the year 2100 – corresponding to a high emissions ‘business-as-usual’ scenario, which is appropriate to use when considering high risks. 3-degree scenario: NGFS Current Policies A scenario which sees the UK make incremental progress to mitigate climate change, but assumes no major policy changes and results in missing the targets of the Paris Agreement. Policy ambition 3ºC+ Government policy None – current policies Technology change Slow change Physical climate risk scenarios Climate Transition risk scenarios TCFD and TNFD continued 102 Annual Report and Accounts 2024 « Pennon Group plc Physical climate risks – scenario analysis Approach taken The Group undertook qualitative scenario analysis in 2021 considering the financial implications of physical climate risks for South West Water under two climate scenarios based on the IPCC’s Representative Concentration Pathway (RCP) scenarios. Potential material financial impacts were considered over the 10-year horizon to 2030, aligning with the Group’s regulatory financial viability testing. Material impacts on our business and strategy were considered over the time horizon to 2050 – aligning with a medium-term view of climate change impacts before uncertainty increases beyond 2050. We have extended our analysis to cover Bristol Water (acquired June 2021) and we will look to incorporate SES Water when we update our scenario analysis in future. This year we have revised our scenario analysis based on changes over the past year, using the same physical climate scenarios as the previous years. Impacts This section discusses impacts under both of the physical climate risk scenarios (RCP2.6 and RCP8.5). • Climate resilience will require increased expenditure and investment. The most significant financial impacts for the Group are on our expenditures (Opex and Capex), to mitigate future climate risks by: increasing capacity for water supply infrastructure; managing drought conditions and water demand; improving water and wastewater treatment and odour management; improving operational resilience to flooding, saline intrusion and storms; and enhancing our Upstream and Downstream Thinking programmes. These financial impacts would be significantly greater under the higher emissions scenario over the long-term horizon as they will require higher levels of adaptive capacity, although adaptive planning will seek to minimise this impact by identifying low-regret options under both high and low emissions scenarios to inform investment decisions. These costs could be recoverable through the regulatory system. • Investments in our natural capital will be central to climate adaptation. Within the water industry, healthy and functioning ecosystems are critical for resilient operations. Therefore, the risks to Pennon’s infrastructure are affected by risks to the natural environment. Accordingly, increased expenditures (Opex and Capex) include heavy investment in our natural capital schemes, catchment management, partnerships, and research and development in this area, as well as implementing our comprehensive Biodiversity Strategy and Environment Plan 2050. • Climate impacts will affect our ability to meet performance commitments and objectives. The Group could also be impacted financially by Outcome Delivery Incentive (ODI) penalties and rewards due to potential failure to achieve performance commitments as part of the regulatory framework, further resulting in negative impacts to our reputation. This impact is more likely under the higher emissions scenario over the long-term horizon due to higher projected magnitude of climate impacts and frequency of extreme weather events. • Investment required is high, but the cost of inaction is much higher. Our risk assessment clearly shows long-term significant risks if the impacts of climate change are not mitigated. South West Water operates over £6 billion of water assets and over £7 billion of wastewater assets all of which will be affected by climate change in some way. The unmitigated risk would also result in additional expenditure (Opex and Capex) to recover from service interruptions and repair or replace deteriorated assets. The unmitigated risk would result in more frequent and greater ODI penalties. Although some of this will be our expenditure, wider flood protection investments will be required by others to protect wide-ranging coastal assets. • Impacts are worse with every bit of additional warming. We would experience these impacts for extreme events over all time horizons; however these impacts would increase over each horizon as extreme weather events increase in frequency and magnitude and are compounded by higher average temperatures and drier summer conditions. This trend is more pronounced for the higher emissions scenario, particularly over the long-term horizon, where temperature increases are projected to accelerate. Our strategic response Our strategy for managing physical climate risks and financial impacts is underpinned by the following principles in order to maintain and improve our Company’s performance to the year 2050: • Adapt to climate change • Enhance resilience • Innovate • Become more efficient • Collaborate • Balance investment over time This will require significant action and investment by our Company, as well as action by our supply chain partners and wider actors (e.g. Government agencies, local authorities, and major land owners in SW England). Longer-term investment, as outlined in our strategic plans, will be needed to manage future risks to acceptable/tolerable levels. The long-term risk is significant and will require additional investment to mitigate its effect. To achieve this, regulatory and Government support within their policy frameworks will be needed. The combined characteristics of low population density, high coastline to land area ratio and tourism-based seasonal flux on water demand, present a unique set of challenges. Through the years, by innovating, investing, and adapting, we have achieved industry-leading results in many areas of the business. The extensive programme of environmental improvement with Upstream and Downstream Thinking catchment management has resulted in some of the finest bathing waters in Europe. This has been instrumental for us to tackle these challenges and meet the expectations of our customers. Having seen record visitors to our region following the COVID-19 pandemic, it is expected further investment will be required to continue building on the progress made by Pennon Group to protect the environment and our bathing waters. Our strategic responses within our WRMP24 and DWMP23 for delivering reliable, efficient, and high-quality drinking water and wastewater services are driven by best-value adaptive planning, as per Ofwat’s final methodology for PR24. This means that, using the same physical scenarios analysed here (RCP2.6 and RCP8.5), our WRMP24 has developed adaptive investment programmes which: 1) fulfil immediate and most probable future needs; 2) respond to external pressures in the future with alternative investment options that are triggered under specific conditions; 3) identify low- and least-regret investments that enable future options or return benefits under the broadest range of potential futures. Subsequently, our strategies for mitigating climate risks and building adaptive capacity are similar under the high and low emissions scenario in the short and medium term; however, additional options will be required under the RCP8.5 scenario, or options may need to be implemented earlier than the RCP2.6 scenario over the long term. As part of our adaptive planning approach, we have pre-defined trigger points and decision points to implement strategies of the appropriate pathway sufficiently early, so that we can have a pro-active and more resilient response to climate change - including more opportunity to implement nature-based solutions - rather than more costly reactive approaches which may have higher operational and embodied carbon. Impacts on financial planning Compared to today, overall our revenue is unlikely to be impacted significantly by climate change as we operate in a regulated environment funded through Price Reviews. However, there is a higher risk of reduced regulatory rewards and increased penalties (ODIs) due to climate change. Our operating costs are likely to increase compared to today due to climate change, and additional capital investment will be required. The value of our assets and our cost of capital would remain relatively unchanged compared to today if we continue to enhance our resilience. We continue to integrate the outcomes from climate scenario analysis to inform our business strategy and financial planning. 103Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Climate transition risks – scenario analysis Approach taken The Group undertook qualitative scenario analysis in 2022 considering the financial implications of transition climate risks and opportunities for South West Water (including Bristol Water) under two transition scenarios. The assessment considered impacts to the year 2030; this time horizon was selected as it aligns with our operational Net Zero target and there is much uncertainty beyond this time with regard to changes to policy, technology, markets, and public opinion. This year we have revised our scenario analysis based on changes over the past year, and considering the two new transition scenarios developed by the NGFS described earlier. Impacts – NGFS Current Policies scenario This scenario provides a challenging context for meeting our 2030 operational Net Zero target. In this scenario we have identified the following main impacts for our business: • The cost to our business of achieving our 2030 Net Zero target rises, with less ability to recover costs through the regulatory pricing system. This is compounded by the low readiness and higher costs for access to low-carbon technologies and related skills (due to the UK’s underinvestment in this scenario), and increased costs related to both our own renewable energy generation and the purchasing of green electricity from external suppliers (where demand is likely to outstrip supply). • The current UK policies might not be sufficient to deliver the necessary carbon emission reductions. As such this could impact our business transition through increased higher costs from the reliance on carbon- intensive energy and internal combustion engine vehicles. • Meeting our 2030 target requires greater use of carbon offsets. The enabling environment for decarbonisation is weaker and costs are higher, which leads to slower progress in emissions reductions across our business. As a result, the residual emissions that need to be offset rise, which adds to our costs. • Environmental targets require additional energy use. New guidance on targets for both nutrients and storm overflows will require a significant increase in energy use and associated capital and operational carbon. While nature-based solutions will form part of the solution (our Green First Principle), there will be significant reliance on engineered solutions due to potential inflexibility in regulation and deadlines to improve outcomes. The increased energy and carbon use compounds impacts above. • Reputational risks are significant and require careful management. Some of our customers and stakeholders may have differing priorities and preferences for actions to meet our 2030 target, for example regarding the increased use of carbon offsets. Some may be highly sensitive to affordability, and increasingly scrutinise our investment choices. • Opportunities are lower than the Net Zero 2050 Transition scenario. Opportunities for our business remain; however, they are in general more limited, and with lower return than in the Net Zero 2050 Transition scenario. Increasing efficiency of energy and resource use, and pursuing low-carbon energy alternatives are the primary opportunities and can help to offset some of the additional energy and carbon costs. There is also an opportunity to clearly identify and communicate the synergies between environmental objectives and the transition to a Net Zero business in order to increase support from customers, stakeholders, and regulators. Impacts on financial planning Compared to today, overall our revenue is unlikely to be impacted significantly in this scenario, but also our non-water revenue is less able to grow. Our costs to achieve operational Net Zero may increase relative to our current plans; however, early investment in decarbonising the business to meet the 2030 target remains more cost-effective in the long term (post 2030), and reduces the risk to our Company and our customers from measures such as carbon pricing, as well safeguarding our reputation on environment and climate change. The value of our assets and our cost of capital would remain relatively unchanged compared to today. Impacts – NGFS Net Zero 2050 Scenario This scenario is more favourable to our business and to the UK’s Net Zero goals, as it creates a more supportive enabling environment to achieve our 2030 operational Net Zero target, however this may present challenges balancing trade-offs between the agendas of Net Zero and environmental gains, water quality and climate resilience, environmental protection, addressing customer affordability, and other objectives. In this scenario we have identified the following main impacts for our business: • Cost to our business of achieving our 2030 Net Zero target is lower than the NGFS Current Policies Transition scenario. There is much greater regulatory support in order to support the step change in investment required, with an increase in costs which can be recovered through customers’ bills. The maturity of technology and associated business models progresses rapidly, and helps to drive down costs across many areas, including in renewables, resource efficiency, and demand-side measures. Greater R&D programmes with gated investment and piloting will minimise technology investment risks compared to the Current Policies Transition scenario, where strategies could be more reactive thanproactive. • Access to the skills and resources needed is costly. There is very high demand for low-carbon technologies, skills, and expertise across the economy in this scenario, which significantly outpaces supply (partly due to the UK’s past underinvestment and the time required to develop supply chains). This adds to our costs associated with decarbonisation, and risks delaying key projects. • Environmental targets require additional energy use. This impact is the same as the Current Policies Transition scenario; however the regulatory environment may be more favourable for nature-based solutions (NBS) which can also sequester carbon, as there may be more stringent carbon management requirements, and carbon markets would also be stronger and provide more incentives for NBS. • Enhanced support to low-income customers may be needed. Fairness in the distribution of the costs of the UK’s transition to Net Zero is a key concern among stakeholders. Increased support to some customers may be required, and our investments will need to be carefully planned and phased to ensure they are efficient and avoid sudden price impacts. • Opportunities are higher than in the Current Policies Transition scenario. The more favourable enabling environment means that our opportunities are enhanced in this scenario, and they are easier to realise. There are particular opportunities to further invest and innovate on energy and resource efficiency, and to attract further investment through sustainable finance opportunities. TCFD and TNFD continued 104 Annual Report and Accounts 2024 « Pennon Group plc Impacts on financial planning Compared to today, overall our revenue is unlikely to be impacted significantly in this scenario, but our non-water revenue has greater potential to grow. Our costs to achieve Net Zero may remain largely unchanged compared to today. The value of our assets may increase as we decarbonise and enhance our natural capital, and our cost of capital may decrease compared to today. Our strategic response Although there are important differences in the impacts between the different transition scenarios, there are a number of common elements which will require us to implement a common strategic response. The relative importance of each, and specific elements within the response, will vary across the two scenarios, but we have identified six key focus areas which will enhance resilience to transition risks, and better position the Group to take advantage of opportunities: • Investing in efficiency. Under both scenarios there are major carbon savings that can be achieved by increasing efficiency, in energy use (for example more efficient pumping), reducing water losses, and through the use of smart technology to enable more efficient water supply and transmission systems. Some of these opportunities will also reduce costs. We are currently investing in programmes to further reduce energy use and carbon across our operations. This will allow us to more rapidly progress to operational Net Zero and reduce the cost of the transition. • Enhancing our energy resilience. We will continue to invest in generating our own renewable energy to reduce our exposure to energy prices and to enhance our options for energy supply, which is favourable under both scenarios. • Enhancing our access to Green Economy resources. Across both scenarios there will be a shortage of skills and resources across key areas of the Green Economy that we will need to support our transition. To manage this we will diversify our supply chain of low-carbon suppliers, and invest in a programme of internal capacity-building to ensure access to the skills needed. We will also work with partners across the industry and engage with peers, regulators, and Government to enable rapid investment in the skills and capacity needed to support Net Zero. • Engage and influence environmental targets and trade-offs. New ambitious targets on nutrients and storm overflows will require increased energy use and new infrastructure, and subsequently higher operational and capital carbon. There is a trade-off between action to meet these targets and action on decarbonisation, with implications for the balance between nature-based and engineering solutions. We will engage in ongoing consultations on environmental targets and strategies for meeting them, and seek clear guidance on managing different trade-offs. We will advocate for policies which enable flexibility and time to scale up nature-based solutions so we can maximise co-benefits for our customers and the environment. • Enhance our stakeholder and customer engagement. There are significant reputational risks associated with both scenarios, although the balance of concerns will vary. We will develop plans for enhanced programmes of engagement and communication with our customers and stakeholders, in particular focusing on explaining the costs and benefits of the investments we are making, potential trade-offs and synergies between Net Zero and other environmental targets, and affordability. • Pursue opportunities to deliver more value for customers and shareholders. We will continue to pursue opportunities to reduce costs and enhance sustainability. This includes reducing our financing costs through our sustainable finance framework, investing in our environmental programme which includes restoring ecosystems to capture carbon, and working with partners and suppliers to enhance our resilience and reduce emissions across our supply chain. We will also continue to explore opportunities to enhance our revenue through water resource options, selling renewable energy, and markets for bioresources and naturalcapital. We continue to integrate the outcomes from climate scenario analysis toinform our business strategy and financial planning. Statement of resilience There are clear impacts on our business under different climate scenarios, inparticular: • higher costs in the short term to meet our operational Net Zero target by2030 under the Current Policies Transition scenario. • higher costs in the short, medium, and long term under the RCP8.5 Higher Physical Impacts scenario. Several of the strategic responses outlined above are already included in our strategic plans and business plan, and we have confidence that our Company has a range of strategic options to manage the impacts, can take advantage of opportunities, and will remain resilient under the different climate scenarios considered. Further analysis, including quantitative analysis, is planned going forward to enhance Pennon’s confidence related to resilience. There will be the requirement to invest more to improve our resilience to climate change and deliver Net Zero. Assets are likely to require additional protection, and planning for new assets will require a greater level of embedded climate resilience. Significant action and investment will be required by our Company, as well as action by our supply chain partners and wider actors (e.g. Government, local authorities, major landowners/users, other providers of infrastructure and services). 105Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Nature-related risks and opportunities - strategy Our business planning and financial planning are underpinned by a series of environmental strategies, plans and commitments that interlink up to 2050. Key examples include: • Growing Nature to 2035: our strategy for nature recovery, which sets out the key activities that we will take to support nature recovery and biodiversity on our land, in our everyday operations and beyond. There are three principles in the strategy: 1) Protect the best – take action to protect the valuable biodiversity that we have on our landholdings, 2) Restore and enhance the rest – take action across our landholdings and assets to enhance biodiversity in the everyday management of our sites, and 3) Beyond our landholdings – work in partnership with others across the region, taking a catchment approach to deliver biodiversity enhancement and nature recovery. These principles align with the LEAP process advocated by the TNFD, by taking a site approach (locate), formulating plans to monitor those sites via undertaking biodiversity baselining and natural capital assessments (evaluate), and creating management plans (assess) with actions to work across the estate with own staff (e.g. Nature Safe) and external partners, to improve the biodiversity condition. The outputs of these plans will enable Pennon to prepare to respond to and report on, material nature-related issues. Our biodiversity strategy aligns fully with our PR24 Business Plan. • Our ‘Green First’ Framework, published May 2023, sets out our approach to utilise NBS and natural flood management wherever possible and practicable. As such, our planning assumptions are based on achieving 50% reduction in surface water flow entering sewers, through nature- based solutions and a minimum removal of 10% of impermeable surfaces. • The launch of WaterFit in 2022 is our plan for healthy rivers and seas as part of c.£100 million of investment to 2025 focused on the protection of our 860 miles of coastline and rivers in the South West. This includes an additional c.£45m reinvestment of out-performance. • Our catchment management initiative, Upstream Thinking, applies natural solutions to reduce agricultural impact on biodiversity and water quality. It does so whilst supporting farmers and the rural economy in providing long-term resilience to climate change, by: installing waterside fencing, building ponds, improving farm tracks, increasing slurry storage and planting trees and buffer strips to catch and filter water. • In early 2024, our Board approved a pilot programme of bespoke, evidence based “Natural Catchment Management Plans” (NCMPs) at selected catchments in Devon and Cornwall ready for June 2024. These are intended to create a blueprint to be rolled out for all bathing water catchments from 2025 onwards, primarily in relation to bathing water quality issues. These can be used to create a “story map” of water management issues and opportunities in each catchment for engaging local stakeholders and partners in identifying actions for local collaboration. • In preparation for the next Asset Management Period AMP8, our Tier 1 suppliers are being tested for their ability to deliver NBS for wastewater and drinking water. Our ESG team is investigating the social aspects and carbon emissions of Pennon’s supply chain and hopes to expand this to consider nature-related dependencies, risks, and opportunities inthenearfuture. Going forward: • From April 2025 onwards, we are establishing an independent Environmental Advisory Panel composed of environmental experts which, amongst other functions, will advise on risks and opportunities and monitor progress on our Biodiversity Performance Commitment. Wearecurrently developing the Terms of Reference for this Panel. • The new Biodiversity Performance Commitment requires all water companies to set out their plans for delivering measurable biodiversity enhancement units using the Defra/Natural England biodiversity metric. These will be achieved as a result of the actions that we will deliver under our nature plans and strategies across the areas we serve. • We are creating a ‘Nature Safe Framework’ to support our employees and contractors across operational sites to understand and protect nature - inalignment with our Biodiversity Strategy. We are in the scoping phase and envisage this framework to be analogous to our ‘Home Safe Framework’ related to employee health and safety. • Over the next year we will continue to develop our approach to embedding nature-risk and opportunity management across our business. Risk management Disclose how the organisation identifies, assesses, and manages climate- related and nature-related risks. The Group’s risk management framework is explained in detail on pages 55 to 64, including the methodology for assessing risks. The Group is continuing to integrate climate-related and nature-related risk management within the Group’s overall risk management process. Climate-related and nature-related risks and opportunities are assessed using the same methodology as other business risks. In the past few years we have undertaken specific work to identify and assess climate-related risks and opportunities, and we are moving towards this risk identification and assessment being integrated within business subsidiaries/functions. We have the processes in place to enable this integration, and a key area we are continuing to work on is raising awareness and competency so that the key people across our subsidiaries/business functions can effectively identify climate-related and nature-related risks, as they do other risks (in many cases, climate and nature risks are an amplifier or additional driver to risks we have already identified, rather than presenting novel risks). This year and last year we convened workshops with senior management from across business functions to re-visit and re-assess climate-related risks and actions, and management will take forward the responsibility to integrate climate- risks into risk registers owned by each business subsidiary/function. Furthering our progress, the Group has identified several principal risks which are impacted or influenced by physical and transitional climate and nature risks and opportunities, and as such we are increasingly cognisant that climate and nature risk management is integral to the performance and resilience of our business and strategy. The link between climate-related and nature-related risks and opportunities and our principal risks is summarised in the table over the page. TCFD and TNFD continued 106 Annual Report and Accounts 2024 « Pennon Group plc We recognise that evolving landscape of climate-related and nature- related risk is reflected in the changing regulatory frameworks, customer expectations and Government policies that are inherent to our operating context. This is particularly true for climate change, nature, and Net Zero where new policies and technologies are rapidly emerging, and markets arerapidly changing. For the climate-related risks that have been identified, a desired ‘target’ net risk level is documented within the Group’s risk framework. This target risk level or tolerance level reflects the acceptable level of risk by the Group and also stands as a target and equitable measure for alleviatory measures to approach the risk going forward. We seek to minimise risks on operational activities within the regulatory environment. Climate- related risks are approached with a minimal level of appetite, although this is subject to Boardapproval where all appetite levels are established. Environmental compliance requirements are high so our risk appetite for environmental impacts is low. Where there is no risk to regulatory compliance, we are willing to take more risks to innovate e.g. NBS. The appropriate action then follows from the level of difference between the net risk and the desired risk appetite. Actions to manage risks cover four response types: • Tolerate: where decisions are taken to tolerate a risk, subject to ongoing monitoring. An example is climate-related risks where uncertainty is high and therefore we might decide to monitor risks until such time as it may be necessary to take further action. • Treat: where actions are taken to manage and reduce risks, such as implementing operational measures in our drought plan or capital investments to enhance our resilience to droughts. • Transfer: used where possible to transfer risks to other organisations - such as through insurance or through contracting out responsibilities. We recognise it is not possible to fully transfer risks, rather this approach helps to reduce our exposure; for example, to the impacts of flooding through flood insurance. • Terminate: where decisions are taken to stop activities so that we are not exposed to particular risks. For example, we may decide not to undertake a capital project if risks cannot be effectively mitigated - for example due to high costs for energy, materials, and specialist resources related to Net Zero or climate adaptation. Actions to mitigate risks are allocated to action owners and progress is monitored through the risk review process. Climate-related and nature-related risks impact and influence our principal risks Below we outline our principal risks which are impacted or influenced by climate- and nature-related risks and opportunities, including where our response to these principal risks needs to consider nature recovery, climate change, and Net Zero. The climate and nature emergency are amplifying our principal risks.

Our Climate Adaptation Report provided to DEFRA in 2021 it shows intolerable levels of physical climate risks if left unmitigated. In addition, at least 17 of the top 20 physical climate risks (>60 risks identified) would exceed this threshold by 2080 without further adaptation. This signals the need for further investment in climate resilience in future planning rounds. Our Net Zero carbon commitments will provide a step change to how we run our business and look to manage the risks of climate change; an update on our progress during the last year is found on pages 69 and 70. The metrics and targets associated with this help to show the investment in the area and the planned future investment to meet this goal. Further detail on our progress with nature and environmental initiatives is provided on page 78. All projects being put forward to the planning committee have a focus on both their carbon impacts and the ESG impacts which are used to manage the decision-making process. 109Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Read more Related Policies Due diligence processes Policy outcomes Principal risks Non-financial KPIs Climate and environment Our ambition is to become Net Zero by 2030.

Dear Shareholder I am very pleased to introduce, on behalf of the Board, the Pennon Group Corporate Governance Report for 2024, which sets out our governance practices and processes, and how we applied the principles of the UK Corporate Governance Code 2018 (the Code) throughout the year. Thereport covers our key focus areas and achievements during 2023/24 andexplains how the Board continues to operate effectively and efficiently and tosupport the Group’s strategy. Review of the year We continue to operate to the highest standards of corporate governance. Strong governance remains central to the successful management of the Group, providing the framework we need to deliver our strategy, fulfil our purpose, create value for all our stakeholders and continuously develop ourbusiness. The table on page 112 will help you to navigate our reporting and evaluate our performance against the Principles of the Code. As we explain below, we also have processes and procedures in place to safeguard the independence of decision-making by the Board of South West Water. Throughout 2023/24 the Board remained focussed on achieving our strategic priorities and in January 2024 the Board were delighted to announce the purchase of Sumisho Osaka Gas Water UK Limited, the holding company of Sutton and East Surrey Water plc (SES Water). SES Water is a well-run, established business with a long heritage in the region, which Pennon recognises as key to delivering for our customers and communities. In addition to the above, in October 2023, the Board approved the Group’s PR24 plans to double its investment to £2.8 billion from 2025-30 across four key areas - water quality and resilience; tackling storm overflows and pollutions; delivering for customers and addressing affordability; reaching netzero and enhancing environmental gains. More information on the Board’s activities can be found on pages 124 to 125 and information on our PR24 framework can be found on pages 19 to 20. Changes to the Board There were a number of changes to the Board during the year. As previously announced, Neil Cooper stepped down from the Board in September 2023 asSenior Independent Director and we were very pleased to appoint Iain Evans as his successor. Iain has served on the Board since 2018. He brings awealth of experience in the water business and is well equipped for this new role. On behalf of the Board, I would like to thank Neil for his wise counsel, experience and all his work over the years and we wish him all the best for the future. Following Neil’s departure, a review of the composition of each Board Committee was conducted and we were pleased to appoint Loraine Woodhouse as Chair of the Audit Committee in September 2023. Further details can be found on page 136. In December 2023, Paul Boote stepped down from his role as Group Chief Financial Officer as part of a planned relocation away from the South West. Iwould like to thank Paul for his contribution and support to Pennon over thepast 13 years and we wish him and his family the best for their future. We were delighted to welcome Steve Buck who was appointed to the Board in November 2023 and succeeded to the role of Group Chief Financial Officer on 1 st January 2024. Steve brings to the Board significant water sector expertise, alongside broad regulated utilities sector knowledge and listed experience to the Board. Steve’s and Iain’s biographies can be found on pages 116 to 117. 114 Annual Report and Accounts 2024 « Pennon Group plc Promoting diversity Diversity and inclusion (D&I) continued to be a top priority for the Board and the Group during the year. Our Board composition is substantially ahead of the diversity targets suggested by the Parker Review and the FTSE Women Leaders Review and Pennon is one of the rare FTSE-listed entities where women on the Board outnumber their male counterparts. During the year, wewere incredibly proud to achieve third position for best performers inWomen on Boards within the entire FTSE 250. Our commitment to diversity is also reflected right across the business; our widespread commitment and focused drive to recruit talent from all backgrounds has the heartfelt support of our strong and diverse leadership team. More information on our D&I initiatives can be found on page 28 and inthe Nomination Report on page 132. Engaging with our stakeholders Engaging with all our stakeholders has never been more essential, particularly in view of the national and global issues we are facing. All companies in the water sector face much scrutiny around their environmental impacts, so it is vital that we listen to and respond to our stakeholders’ views. We make sure to carefully consider all decisions and their likely impacts on our stakeholders. Engagement with customers is of particular interest to the Board and as part of the PR24 process, we were delighted that Lord Matthew Taylor, Chair of the WaterShare+ panel, and Peaches Golding OBE, Chair of the Bristol Water Challenge Group, regularly attended Board meetings to provide feedback from their discussions with our customers as part of their work with the WaterShare+ panel. Further information on the important work of the WaterShare+ panel can be found on page 8. We continue to foster an open and transparent feedback culture within the business. All colleagues have the opportunity to share feedback with the Executive team and Board in several ways, including the Big Chat initiative, our Great Place to Work survey and our Employee Forum RISE. You can read more on how we engage with our stakeholders on pages 126to127 and in our Section 172(1) statement on page 128. Culture As a Board we pay particular attention to our Group’s culture, ensuring it is fully aligned with our shared purpose, values, and strategy. We continue to monitor these essential properties and receive regular reports from management on the work being done to ensure their continuous improvement. During the year, the Board were delighted to see the development of the Group’s new values which reflect the views of our wider stakeholders and culture. More information on how the new values will be embedded across the Group can be found on page 25. Role of the Board and its effectiveness It is my view that the Board continues to be highly effective with a deep understanding of the opportunities available to us and the threats facing the business. The results of this year’s Board and Committee performance reviews support this view; see page 135 for further detail. We keep all identified threats to the future success of the business under constant review. Please see our risk report on pages 55 to 64 for a description of the risks we identify and review. Board independence – Pennon and South West Water In accordance with Ofwat’s principles on board leadership, transparency andgovernance, the Group maintains separate boards for Pennon and SouthWest Water. Our system of governance remains appropriate and effective, while continuing to support the delivery of our strategy. Our Board and Committee framework also allows us to remain efficient in our decision-making processes. The South West Water Board convenes on the same day as each Pennon Board meeting and considers all key relevant issues. This arrangement allows full operational oversight and governance by the boards over the Group’s water interests, while the Pennon Board continues to focus on strategic forward-looking matters for the Group as a whole. Looking ahead As part of the Board’s focus for 2024/25, we will, once the Competition and Markets Authority process has completed, look to integrate SES Water into the Group. We will continue our focus on delivering against our environmental commitments, and ensuring we are well placed to meet the vital ambitions of the PR24 framework. And, as we look to our governance arrangements, we will continue with our ongoing and orderly succession planning strategy. There is much to do, and we have the talent and governance in place to achieve our ambitions. As I reported in last year’s Annual Report, I will be standing down as Chair, and from the Board, at the conclusion of the AGM on 24 th July 2024. We are conducting a formal, rigorous and independently conducted process, in the line with the Code, I will be announcing the new Chair of the Group shortly. I would like to take this opportunity to thank my Board colleagues, the management team and our wider workforce for their outstanding work over the year just gone. The Board will continue to focus on delivering against our strategic priorities in the year ahead, ensuring the wellbeing of our workforce as we build on the work of the last year in creating a successful and sustainable business.

Workforce engagement The Board has decided, at this time, not to adopt any of the three specific employee engagement methods referred to in the UK Code. Instead, our chosen method is to adopt a more enhanced approach which includes the conduct of a periodic ‘Great Place to Work’ engagement survey (including related management feedback sessions) and continuous employee feedback through our own in-house forums. These comprise our RISE people panel, a forum for employee engagement, and the ‘Big Chat’, hosted on a monthly basis by the Executive team. These forums not only give employees access to important up-to-date information on key business events; they also provide the opportunity to hear from the Directors, give feedback and ask questions. The Board believes Pennon’s chosen approach is an effective way of communicating with employees and gathering essential feedback from across the business. This empowers the Board to consider the interests ofall employees in its discussions and decision-making. You can find further information on employee engagement on pages 25 to 31. Stakeholder engagement In delivering our strategy and ensuring the sustainable, long-term success of the Company, the Board places utmost importance on the interests of our stakeholders in its decision-making process.

Workforce policies and Practices Conflicts of interest In accordance with the Directors’ interest provision of the Companies Act 2006 and the Company’s Articles of Association, the Board has in place a procedure for the consideration and authorisation of Directors’ conflicts or possible conflicts with the Company’s interests. The Board considers this has operated effectively during the year. Each Director has a duty under the Companies Act 2006 to avoid a situation in which they have or may have a direct or indirect interest that conflicts or might conflict with the interests of the Company. This duty is in addition to the duty owed to the Company to disclose to the Board any interest in a transaction or arrangement under consideration by the Company. A register of Directors’ conflicts is maintained and reviewed at each Board meeting. Authorised conflicts disclosed on the register currently involve cross-directorships with Pennon Water Services Limited and the trustee board of the Group’s defined benefit pension scheme. Whistleblowing The Board maintains overall responsibility for the Company’s Whistleblowing Policy (the Policy). The Policy provides a clear procedure for employees and suppliers to report concerns, through the Speak Up service, either to their line manager or through a third-party whistleblowing hotline. The Policy is well communicated to employees across the Group. All whistleblowing cases are investigated by the Ethics Management Committee. The Board, through the Audit Committee, receives yearly whistleblowing updates which set out any whistleblowing issues raised during the period and interim updates on any significant matters. The updates provided are anonymous and summarise the result of any investigation. The Board is satisfied that the Policy and the work of the Ethics Management Committee remain effective. 123Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information 123Pennon Group plc » Annual Report and Accounts 2024 Key activities of the Board In 2023/24, the Board considered a wide range of matters.

We are committed to carrying out our business in a responsible way and to continuously improving how we provide all our services for the benefit of all our stakeholders. Our section 172(1) statement describes in more detail how the Board considers the interests of all our stakeholders when carrying out its duties. This statement is on pages 128 to 129; you should read it alongside the ‘How we Listen’ section on pages 8 to 12 to understand why we engage with our stakeholders, how we engage, the key challenges we face and how we areresponding. We actively engage with all our stakeholders, including our customers, our communities, our people, our suppliers and our investors. We are acutely aware that many of our stakeholders are struggling with the uncertainty posed by the cost-of-living crisis, the political landscape and the wider economic environment. We are committed to maintaining appropriate and regular dialogue to ensure our strategy and our performance objectives always reflect our stakeholders’ expectations and needs. Our continuous engagement allows stakeholders to give feedback on matters they consider of importance to them and raise any issues which they would like to be addressed. Engaging with our customers and communities The WaterShare+ scheme was developed in direct response to feedback from our customers who said they would like to share in the success of the Company, alongside giving them a greater say in our business. The first WaterShare+ scheme was launched in 2020 and returned £20 million to customers as a reduction of £20 on their bill. Eligible customers had the option of choosing a minimum of £20 in Pennon shares. In November 2022, the second WaterShare+ scheme was launched and returned c.£20 million to customers of South West Water (including Bournemouth Water) and for the first time, customers of Bristol Water. Eligible customers could choose between a £13 reduction on their bill or to opt for a shareholding in the Pennon Group. As a result of this second issuance, we have extended customer ownership and 1 in 14 customers of South West Water are now also a shareholder via this scheme. The WaterShare+ customer meetings are an opportunity for our customers to provide direct feedback to our independent WaterShare+ Advisory Panel, who, inturn, provide direct feedback to our Board. During the year, as part of our PR24 Business Plan discussion, the Chair and Deputy Chair of the WaterShare+ Advisory panel, Lord Matthew Taylor and Peaches Golding OBE, respectively, attended three PR24 Committee meetings to provide feedback following their discussions with customers. In turn the chair of the PR24 Committee attended one of the WaterShare+ public meetings that was focused on PR24. The dialogue at these meetings ensured that the interests of our customers remain a top priority, and that the delivery of the PR24 Business plan had the utmost focus on the benefit to our customers and our communities. The Group Chief Executive Officer’s monthly report, which is presented to the Board and discussed at every meeting, includes updates on customer engagement sessions conducted as part of the PR24 Business plan process, through the “Your Water, Your Say” sessions which were held in May and November 2023. Customer engagement on the WaterFit programme through the “Your Beach, Your Say, Our Investment” interaction sessions with local communities and stakeholder groups, and responses received from our interactive map “WaterFit Live”, ensure that valuable feedback is provided to the Board, which assists in ensuring that significant investments are made in order to protect our rivers, seas and wider environment. Engaging with our people The Board receives regular updates on our people from the Group Chief Executive Officer and Group Chief People Officer at its meetings. The Great Place to Work survey and feedback from RISE panel provided to the Board ensure that the decisions made consider employee interests and include what is of priority to our people. Further details on the engagement with our people can be found on page 10.

The CEO and Executive Team hosted site visits from the Defra Water Minister, the Shadow Water Minister and the Chair of the Environment Agency, facilitating discussion on the strategic issues of particular importance in the South West. Through our ‘Quality First’ transformation programme in the South West region and continued engagement we have seen positive improvements in the relationship with the DWI.

The CEO gave updates to the Board on engagements and collaborations with Water UK, and its Board, ensuring that the water industry’s position on increased investments to improve the sector for the benefit of our stakeholders, remains a key government focus. The CEO also attends, on occasion, the Let’s Talk Water environmental stakeholder forum which is a key channel for sharing progress on our environmental programme and gathering feedback on our PR24 business plan.

Engaging with our suppliers The Board receives updates at Board meetings on our engagement with suppliers which is conducted through formal Request for Proposal processes and periodic supplier review meetings to ensure that our suppliers deliver outcomes that benefit all our stakeholders. The Board is regularly informed and involved through the stages of tender processes which are undertaken to ensure that suitable and experienced suppliers are contracted to deliver our capital projects, particularly the execution of Pennon Power projects during the year. During the year, the Board received updates from the Group Chief Executive Officer on our engagement with the Cabinet Office on the drafting of the Procurement Act 2023 which is geared towards making procurement simpler, quicker and more transparent given the criticality of supply chain in the future delivery of our business. The Executive team are actively engaging the wider industry supply chain directly and indirectly through organisations such as British Water, Future Water and the Civil Engineering Contractors Association to both understand and influence emerging trends and mobilise the best suppliers and innovation for the benefit of the Group.

This helps us live our purpose and our values as a responsible, trusted and sustainable business acting in a way which benefits all our stakeholders as much as possible.

Key decision Outcome Board discussion and s.172 considerations Link to strategy SES Water acquisition and £180 million equity capital raise In January 2024, the Board approved the acquisition of SES Water and a £180 million equity raise to ensure that the Group remained within the regulated water business gearing range, following completion of the acquisition. In making their decision, the directors considered the impact of the acquisition on all of our stakeholders, and in particular: Our Investors The Board noted that the long-term financial benefits from value creation and the significant increase in total RCV of the Group would benefit the Company’s investors. Our People The Board considered how the acquisition would be perceived by the Group’s workforce and the positive impact job stability and career opportunities would have on SES employees, following the acquisition. Welcoming SES employees to the Group would also enable access to a new, wider and diverse talent pool in Southern England. Our Customers In addition to a more robust and reliable service to SES customers, greater advocacy, involvement, and ownership in their local water company via the WaterShare+ scheme would benefit SES customers. £ Pennon Power projects acquisition In FY2023/24, the Board approved the acquisition of four new renewable energy generation projects through its direct subsidiary, Pennon Power Limited. To foster the long term growth of our environmental infrastructure and accelerate our Net Zero plans, the Board considered the risks and opportunities the renewable projects would provide to the Group and its stakeholders. Our Environment and Communities These projects would see Pennon generating low-cost and low-carbon electricity which would reduce carbon emissions. In addition, the zero carbon electricity generated will power many homes across the UK and foster a sustainable future. Our Customers Reduced operating costs thanks to renewable energy generation, would have a positive impact on customer bills. PR24 Business Plan In October 2023, the Board approved our PR24 Business Plan which sets out what we intend to deliver for our customers and the environment during the period 2025- 2030. As part of their considerations, the Board discussed the £2.8 billion investment plan, which involves engaging 250,000 of our stakeholders over a three-year period. The PR24 Business Plan affects every one of our stakeholders. Our People The Board considered the impact of the PR24 Business Plan on the workforce. Around 2,000 jobs will be created, providing local people with rewarding careers in their home region, either directly employed by South West Water or within the wider supply chain. Our Customers The Board considered the relationship between the cost of the scheme, the impact on bills, and the need to ensure that these remain affordable for customers particularly in the cost of living crisis. The Board judged that the impact of the four priorities within the plan would boost water resources for customers across the region. Our Environment The Board considered the impact of the plan on the environment, and the need to ensure that investments create a sustainable future and accelerate net zero and environmental gains through creation of climate-independent water sources, and restoration schemes to boost natural habitats and nurture healthier rivers and seas. Our Regulators As part of their discussions, the Board considered our regulators. The Board considers that the plan meets Ofwat’s quality and ambition assessments and is aligned with Ofwat’s objectives for PR24. £ Interim dividend declaration In November 2023, the Board approved the payment of an interim dividend of 14.04p per ordinary share. As part of their discussion, the Board considered our stakeholders and the importance of dividends for the long-term success of the Company.

This year, the Committee has overseen a number of planned changes to the Board. As previously announced, in September 2023, Neil Cooper stepped down from the Board having reached his maximum tenure. Iain Evans was appointed Senior Independent Director as his successor. In addition, we welcomed Steve Buck to the Board as our new Group Chief Financial Officer, following Paul Boote’s decision to leave the Company as part of a planned relocation away from the South West. The appointment of Steve is in line with our succession plan to ensure relevant skills and diversity of perspective, given Steve’s previous knowledge of the water sector and significant utilities experience. As noted in last year’s Committee Report, a key focus for the Committee in 2023/24 was to appoint a successor for my role as Group Chair. The Inzito Partnership were appointed as independent consultants, following a robust procurement process, and have worked alongside the Committee in the rigorous selection process, including meetings with appropriate stakeholders as well as the interview process with Board members. The Committee held four scheduled meetings during the year and also held a number of ad-hoc meetings, in person and by Teams call, to fulfil the duties set out in its terms of reference. Only the members of the Committee are entitled to attend the Committee meetings, but other regular invitees to Committee meetings during the year included the Group Chief Executive Officer, the Group General Counsel and Company Secretary and the Group Chief People Officer. Committee members are also excluded from participating when their own positions are under discussion.

Resigned 1 st September 2023 131Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Nomination Committee report continued Board diversity At Pennon, we believe that a diverse and inclusive culture is a strategic imperative, treating it in the same way we do each strategic priority - setting the tone from the top, holding leaders accountable and delivering against aclear action plan. The Committee maintains its strong interest in the Group’s progress in championing diversity, whether in relation to gender, ethnicity, or social mobility, and regularly reviews the demographics of the workforce as well as the leadership. We believe having a diverse mix of minds has helped to deliver a step change in our culture, as a more caring and considerate business, that places significant focus on wellbeing. As of 31 st March 2024, female representation on the Board stood at 63%. In the 2024 edition of the FTSE Women Leaders Report, Pennon emerges as a leader, proudly showcasing its commitment to diversity. The report, independently conducted and backed by the Government, is a ringing endorsement of Pennon’s relentless efforts to lead the charge in fostering equality and inclusivity. Despite progress across the FTSE, Pennon is still one of only a few businesses in the UK to have both a female Chief Executive Officer and Chair. Given this, we have continued our membership of the 30% Club, and Gill Rider and Susan Davy are both ambassadors of 25 x 25, the initiative to improve female representation in senior executive roles. The Group is an advocate of Sir John Parker’s review of ethnic board diversity, meeting the external targets required of a responsible and inclusive business ahead of the required dates. For the second year running, in line with our commitment to the Change the Race Ratio campaign, we have also voluntarily published our ethnicity pay gap of 11.87% (mean). The Committee will continue to monitor pay gaps. Building our representation across the Group is a focus, given the area we serve has lower representation than the national average, where ethnic representation is 6.9%. Our Group ethnic diversity has increased slightly in the year to just over 3%. Board Diversity, Respect and Inclusion Policy The Board requires the Committee to review and monitor compliance with the Board’s Diversity, Respect and Inclusion Policy and report on the targets, achievement against those targets and overall compliance in the Annual Report each year. The Policy was reviewed in March 2024. The Board’s diversity and inclusion policy confirms that the Board is committed to: 1. The search for Board candidates being conducted, and appointments made, on merit, against objective criteria whilst promoting diversity of gender, social and ethnic backgrounds. In this context, the Board will endeavour to achieve and maintain: a. A minimum of 33% female representation on the Board. b. One Board member as a minimum who is racially or ethnically diverse. c. A minimum of 33% female representation on the Group’s senior management team. d. Satisfying itself that plans for orderly succession of appointments to the Board and to senior management maintain an appropriate balance of skills and experience within the Group and on the Board and ensure progressive refreshing of the Board. The approach to Company-wide diversity is detailed on page 28 and is also fully applicable to our Remuneration, Audit and Nomination Committees; and as each Committee is composed of members of the Board, the Board’s Diversity, Respect and Inclusion Policy detailed above similarly applies. I can confirm we currently exceed the Policy targets. Colleagues including our Board and leadership are asked to provide personal information for the purposes of monitoring equality and for statutory reporting purposes, including the FCA diversity disclosures and gender and ethnicity pay gap report. This is collected during recruitment and on-boarding and colleagues are asked to periodically review and update as necessary. Information is stored on the Group’s HR management system, including the data used to populate the table below. Employees are encouraged to provide information on a voluntary basis. FCA diversity disclosure table The Committee is pleased to report against the FCA’s new diversity disclosure requirements, as set out in the table below. At Pennon ‘executive management’ is defined as the Pennon Executive Board. The figures in the table are stated as at 31 st March 2024 and have been calculated based on diversity data provided upon employment.

Dear Shareholder On behalf of the Board, I am pleased to present the Audit Committee’s report for the year ended 31 st March 2024. This is my first report as Audit Committee Chair having succeeded Neil Cooper on 1 st September 2023. This report is intended to provide shareholders with an insight into the work of the Audit Committee (‘the Committee’) together with details of how the Committee has discharged its responsibilities throughout the year and overseen the process of assurance over the integrity of the 2024 Annual Report and Accounts (‘the 2024 Annual Report’). As in previous years, we have focused on the following key priority areas: • Ensuring the quality and integrity of the Group’s financial reporting through the assessment of accounting policy application given underlying standards, challenging management through the review of accounting judgements made in preparing financial reporting, and the Committee’s assessment of whether the financial reporting of the Group is presented in a fair, balanced and understandable manner. • Ensuring the 2024 Annual Report is aligned with the requirements of and guidance from regulators, and that all matters reported on, and disclosed, meet the needs of our various stakeholders. • Monitoring and reviewing the ongoing effectiveness of the Group’s risk management and internal control environment, including the effectiveness and independence of the Internal Audit function. The Committee uses its collective expertise, with input from the External Auditor, to provide a robust challenge to the approach and judgements made by management in the treatment of financial matters and their resulting disclosures within the financial statements. One of our key roles is to advise the Board that we are satisfied that the 2024 Annual Report is fair, balanced and understandable and that it provides the information necessary for shareholders to assess the Group’s position, trends in performance, business model and strategy. In doing so, we ensure that management’s disclosures reflect the supporting detail, or challenge them to explain and justify their explanation and, if necessary, re-present the information. As part of fulfilling these commitments, we carefully consider the key financial reporting judgements of the management as set out on page 139. Significant matters considered by the Committee both during the year and in relation to the year-end financial statements are laid out in this report. The External Auditor supports this process in the course of the statutory audit. Loraine Woodhouse Chair of the Audit Committee Committee members Date of appointment to Audit Committee Attendance Loraine Woodhouse December 2022 Claire Ighodaro September 2019 Iain Evans September 2023 Neil Cooper 1 September 2014 1. Neil Cooper stepped down as Chair and as a member of the Committee on 1 st September 2023 136 Annual Report and Accounts 2024 « Pennon Group plc The Committee was pleased to advise the Board that this Report met these criteria. Details of our review process can be found on page 139. The Committee discharges its responsibilities throughout the year in accordance with a schedule of business reflecting the annual external reporting cycle of the Group, allowing for appropriate consideration at the right point. This scheduling also allows for consideration on an ad-hoc basis of events as they have arisen. The Committee formally considers the effectiveness of the Group’s risk management and internal control systems. This is achieved through updates on the operation of risk management processes during the year and the outcomes of key assurance activities, including from the Group’s independent Internal Audit function. Additionally, the Audit Committee undertakes risk deep dives focused on aspects of the Group’s principal risks. During 2023/24 the Audit Committee has performed risk deep dives on the following areas: • Engineering supply chain resilience. • Water quality. • Cyber security. More detail on our risk management processes, principal risks and their associated mitigation can be found on pages 55 to 64. The Audit Committee has also been actively engaged and received regular updates during the year on the Group’s preparations for meeting the enhanced requirements set out within the 2024 UK Corporate Governance Code, in particular those aspects in respect of Audit, Risk and Internal Control. Good progress has been made with the initial phase focused on financial reporting related processes and controls. The scope of these preparations during 2024/25 will expand to broader operational, compliance and reporting elements. The Committee has considered the requirements for the Financial Reporting Council’s ”Audit Committees and the External Audit: Minimum Standard”, published in May 2023, and ensured that it complied with this standard in conducting the tender for audit services and its ongoing oversight of the external audit process, as set out in this report. Alongside this focus on our risk processes, we formally reviewed the output of the Group’s financial resilience and health assessments: for a 12-month ‘look forward’ period through our assessment of the Group’s going concern status, and over a period of five years to assess the Group’s continuing viability. This viability assessment has considered a range of financial projections arising from the current challenging and complex external environment with ongoing uncertainties in relation to economic growth, inflation prospects and the impact of the PR24 pricing review for our water businesses. These are modelled through internal scenarios around the deployment of Group cash reserves and which now incorporate the acquisition of SES Water. While the Group maintains a five-year viability assessment period, appropriate for an acquisitive group, South West Water has continued to use a longer assessment period to 2030, since it has a greater visibility of future cash flows, being a regulated business. Our viability statement is reported on page 65. Throughout the year, the Group has remained focused on delivering a resilient performance in UK water, despite a difficult period of cost inflation and scrutiny of the water industry as a whole, as we execute our growth strategy of utilising both organic and acquisitive levers to drive long-term sustainable growth. We are focused on delivering sustainable results for all stakeholders. The acquisition of SES Water is subject to review by the CMA. During the immediate period from acquisition on 10 th January 2024 until CMA clearance is obtained, the SES Water business is operated independently of the rest of the Group. SES Water’s continuing governance processes were therefore relied on by the Pennon Group Audit Committee in fulfilling its overall Group responsibilities. The following matters have been considered by the Committee in respect of the SES Water acquisition: • Considering and reviewing the provisional purchase price allocation accounting and disclosure for the acquisition of SES Water in the full year financial results for the year ended 31 st March 2024. • Considering and approving the alignment of accounting policies of SES Water with Pennon Group plc. • Reviewing and assessing the impact of the SES Water acquisition on the Group’s principal risks. • Considering and approving any changes to the Group’s internal control processes, including the effectiveness of the internal control environment, and monitoring the external audit process in connection with the SES Water acquisition. Finally, I would like to thank Neil for his significant contribution to the Committee over the years and for his help and encouragement as I joined the Group. Equally, I would also like to extend my thanks to the members of the Committee for their support as I settled into my new role as Chair. Loraine Woodhouse Chair of the Audit Committee 20 th May 2024 137Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Audit Committee composition All members of the Committee are Independent Non-Executive Directors of the Board. In accordance with the UK Code, the Board is satisfied that Loraine Woodhouse and Claire Ighodaro, both of whom served on the Committee during the year under review, have recent and relevant financial experience and, inaccordance with FCA Rule 7.1.1R of the FCA’s Disclosure Guidance and Transparency Rules, have competence in accounting or auditing.

Other regular attendees at meetings, at the invitation of the Committee, include the Chair of the Board, the Group Chief Executive Officer, the Group Chief Financial Officer, the Group General Counsel and Company Secretary, Director of Risk and Assurance, Group Financial Controller and the External Auditor. The Committee regularly holds private discussions with the External Auditor without management present. Further, the Committee Chair regularly communicates with the Group Chief Financial Officer, the External Auditor and with Committee members outside the meetings to better understand any issues or areas of concern. Matters of significance in 2023/24 Financial reporting • Reviewed and discussed reports from management on the financial statements, considered management’s significant accounting judgements and the policies being applied, and assessed the findings of the statutory audit in respect of the integrity of the financial reporting of full and half-year results. • Reviewed the internal assessment of going concern and longer-term viability on behalf of the Board. • Reviewed in detail the 2024 Annual Report and advised the Board that the presentation of the 2024 Annual Report is fair, balanced and understandable in accordance with reporting requirements, including the consideration of climate risk in the preparation of the financial statements, and recommended the Board gives approval for publication. External auditor • Oversaw the 2023/24 statutory audit, including the key audit risks and level of materiality applied by the ExternalAuditor. • Assessed the effectiveness of the External Auditor during the year. • Agreed the statutory audit fee for the year ending 31 st March 2024. • Reviewed and approved the non-audit services and related fees provided by the External Auditor for 2023/24. • Conducted a competitive tender process for the role of statutory auditor. Internal controls and risk management • Reviewed the effectiveness of the Group’s risk management framework and its integration into Board and Committee Reporting. • Reviewed the Group’s Risk Appetite Statement prior to making a recommendation to the Board. • Monitored fraud reporting and incidents of whistleblowing, including a review of the Group’s whistleblowing processes and procedures and reporting to the Board on this. • Reviewed the Group risk register as part of the Annual Report process and considered appropriate areas of focus and prioritisation for the internal audit work programme for the financial year. • Carried out deep dives at Committee meetings on principal risk areas. Governance • Considered and approved Group accounting policies and judgements used in the preparation of the financial statements, including any required alignments of Bristol Water’s accounting policies. • Reviewed and considered internal financial policies. • Confirmed compliance with the UK Code. • Held regular meetings with the external auditor and the Group Director of Risk and Assurance without members of management being present. Regarding monitoring of the integrity of the financial statements, which is a key responsibility of the Committee identified in the UK Code, the significant areas of judgement considered in relation to the financial statements for the year ended 31 st March 2024 are set out in the following table, together with details of how each matter was addressed by the Committee. At the Committee’s meetings throughout the year, the Committee and the external auditor have discussed the significant matters arising in respect of financial reporting, together with the areas of particular audit focus, as reported on in the independent auditor’s report on pages 175 to 184. In addition to the significant matters set out in the table below, the Committee considered presentational disclosure matters including the use of non-underlying performance metrics and ensuring a fair presentation of statutory and non-statutory performance and financialmeasures. Audit Committee report continued 138 Annual Report and Accounts 2024 « Pennon Group plc During the year, the Committee’s areas of focus included: Area of focus How the matter was addressed by the Committee Revenue recognition Given the nature of the Group’s revenue, the key areas of income statement judgement for South West Water, Pennon Water Services and SES Water continue to be in respect of revenue recognition relating to income from water services. While the Committee relied on the operational businesses’ processes for assessment of water into supply, in the previous financial year it challenged the robustness and timeliness of the methodology used, resulting in management streamlining the calculation approach. The improvements that were implemented in FY23/24 continue to provide a more efficient approach to the calculations required and the Committee continues to scrutinise the track record of accuracy by comparing actual outturns with accruals at previous year ends to form a judgement about the quality of decision making. The Committee also closely considered the work in respect of these areas at year end by the external auditor as well as reviewing disclosures around revenue recognition accounting policies. Bad and doubtful debts Regular updates on progress against debt collection targets and other contractual payments due are received by the Board. Performance is monitored regularly across the Group against historical standards and compared to the track records of other companies in the relevant sectors. The Committee was particularly mindful of the ongoing impacts of affordability on the assessment of expected credit losses in determining the bad debt provision, noting the significant increases in inflation arising from macroeconomic developments. At the year end, the external auditor reported on the work it had performed, which, together with the detailed analysis reported, enabled the Committee to conclude that management’s assessment of the year-end position and its provisions for expected credit losses were reasonable. Going concern basis for the preparation of the financial statements and viability statement A report from the Group Chief Financial Officer on the financial performance of the Group, including forward-looking estimates of covenant compliance and funding levels under different scenarios, including inflationary scenarios, is provided to the Board on a periodic basis. Rolling five-year strategy projections, and the resultant headroom relative to borrowings, are also regularly reviewed by the Board, including the application of scenarios to enable the Committee to better understand the potential range of outcomes. At the end of each six-month period the Group Chief Financial Officer prepares, for consideration by the Committee, a report focusing on the Group’s liquidity over the 12-month period from the date of signing of either the Annual Report or half-year results. The Committee also reviewed a report from the Group Chief Financial Officer on the Group’s financial viability over an appropriate period, in connection with the UK Corporate Governance Code’s requirement for a viability statement to be given by the Board. The Board considers the appropriate period to assess the Group’s viability remains unchanged at five years, which recognises both the longer-term visibility in the regulatory environment of the South West Water and SES Water businesses and the corporate activity, including acquisitions and other non-regulatory investments, such as the recent Bristol Water and SES Water acquisitions and our investments in solar energy generation, undertaken by Pennon. Similarly, this report also considered the viability of the Group, taking into account the potential manifestation of other adverse events modelled from the Group’s principal risks and resultant sensitivity scenarios. In performing its own viability assessment, South West Water uses a longer assessment period to 2030, noting a greater visibility of future cash flows, being a regulated water business. Consideration of these reports and constructive challenge on the findings of the reports, including the scenario testing carried out by management, has enabled the Committee to form its assessment and satisfy itself that it remains appropriate for the Group to continue to adopt the going concern basis of accounting in the preparation of the financial statements and in addition advise the Board on providing the viability statement set out on page 65. Effectiveness of the external audit process Receiving high-quality and effective audit services is of paramount importance to the Committee. We continue to carefully monitor the effectiveness of our External Auditor as well as their independence, while recognising there is a need to use our External Auditor’s firm for certain non-audit services. We have full regard to the FRC’s Ethical Standard and ensure that our procedures and safeguards meet these standards. The External Auditor produced a detailed audit planning report in preparation for the year-end financial statements, which has assisted the auditor in delivering the timely audit of the Group’s Annual Report and which was shared with, and discussed by, the Committee in advance. The effectiveness review of the External Auditor is considered as part of the Committee’s annual performance evaluation, which also examines the relationship and communications between the Committee and the external auditor. Further details of the Committee evaluation are provided on page 135. No issues were raised during that review. The Committee concluded that the Auditor was effective during the year and that the relationship and communications were open and constructive. The Committee Chair has also met privately with the External Auditor to discuss key matters. 139Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Auditor independence The Committee regards independence of the External Auditor as absolutely crucial in safeguarding the integrity of the audit process and takes responsibility for ensuring the three-way relationship between the Committee, the External Auditor and management remains appropriate. The External Auditor reported on its independence during the year, and again since the year end, confirming to the Committee that, based on its assessment, it was independent of the Group. Provision of non-audit services The Committee adopts a robust policy for the engagement of the External Auditor’s firm for non-audit work. The Committee receives a regular report covering the auditor’s fees including details of non-audit fees incurred. Recurrent fees typically relate to agreed procedures regarding annual regulatory reporting obligations to Ofwat; work which is most efficiently andeffectively performed by the statutory auditor. The policy is for non-audit fees not to exceed 70% of the audit fee for statutory work and for the Committee Chair to approve all non-audit work performed by the statutory auditor. The policy uses the average of the last three years’ audit fees disclosed in the accounts reflecting that certain non-audit fees for services required to be performed by the auditors are excluded fromtheassessment. The Committee carefully reviews non-audit work proposed for the statutory auditor, taking into consideration whether it was necessary for the auditor’s firm to carry out such work, and only grants approval for the firm’s appointment if it was satisfied that the auditor’s independence and objectivity would be safeguarded. If another accounting firm could provide the required cost-effective level of experience and expertise in respect of the non-audit services, then such firm would be chosen in preference totheExternal Auditor. The level of non-audit fees payable to the External Auditor for the past year is 18% of the three-year average audit fee, which is within the Group’s 70% non-audit fee limit. The Group Chief Financial Officer regularly reports to the Committee on the extent of services provided to the Company by the External Auditor and the level of fees paid. The fees paid to the External Auditor’s firm for non-audit services and for audit services are set out in note 7 to the financial statements on page 204. Statutory audit tender process and statement of compliance with CMA order The Group complies with the Statutory Audit Services for Large Companies Market Investigation (Mandatory Use of Competitive Tender Processes and Audit Committee Responsibilities) Order 2014. We last undertook a formal comprehensive audit tender process for statutory audit services in 2014. The current External Auditor, Ernst & Young LLP (EY), were appointed following a comprehensive audit tender process and approval by shareholders at the Company’s 2014 AGM. EY commenced their appointment as auditor and presented their first report to shareholders for the year ended 31 st March 2015. The lead audit partner must change every five years. Christabel Cowling, who has considerable audit experience of other FTSE 100 utility companies, has held the role since 2019. This year-end audit is EY’s tenth consecutive year in office as statutory auditor. As announced in our annual report and accounts for FY 2023, the Committee has run a full tender for the Group’s external audit services during the year ending March 2024, before the next rotation becomes due. This allows forany potential new audit firm to take up the role for the year ending March 2025 and, if required, affords appropriate time for a smooth transition ofresponsibilities. Audit Committee report continued Summary of the statutory audit tender process The Committee’s primary objective throughout the tender process, and in making its recommendation to the Board, was to review the audit approach and ensure best practice in the delivery of the Group’s audit. Maximising value to the group and its stakeholders in terms of: audit quality; reliability of assurance; the identification of potential improvements to business and accounting processes and the reporting thereof. In conducting the tender and making an appointment ahead of 1 st April 2024 for the audit for the year ending 31 st March 2025, sufficient time was made available for a firm to cease to provide non-audit services, as set out in the FRC’s Revised Ethical Standard (2019) prior to commencing their tenure and to allow a new auditor to shadow the incumbent during the audit for the year ending 31 st March 2024, if applicable. In addition, the tender process had confirmed that all participants did not provide any services for which a ‘cooling in’ period may apply. A timeline of the process is set out below: 2023 May Committee confirmation of audit tender timetable. August Investor consultation on prospective participants. September/October Expression of Interest confirmations and individual meetings between representatives of interested firms and Chair of the Audit Committee and the Group CFO. November Issue of Request for Proposal (RFP) and provision of information via dataroom. December Meetings with bidding firms to meet Pennon Group personnel including finance, internal audit, information technology and regulatory teams. 2024 January RFP submissions and presentations to selection panel. February Meeting of Audit Committee to consider and discuss findings of the selection panel and to make recommendation to the Board on the proposed candidate. Board consideration and approval of Audit Committee recommendation to appoint its proposed candidate, PricewaterhouseCoopers LLP, as auditor in respect of the year ending 31 st March 2025. 140 Annual Report and Accounts 2024 « Pennon Group plc A working group of the Chair of the Audit Committee, the Group CFO and the Group Financial Controller was established to direct the overall tender process whilst the Audit Committee approved all key decisions as required. The Audit Committee as a whole was kept fully appraised of the progress of the tender by the Chair of the Committee. The Group Financial Controller was responsible for leading on the logistics of the tender process. Ahead of the request for proposal (RFP) being issued, four ‘challenger’ firms confirmed that they did not wish to participate in the tender and a third ‘Big 4’ firm was conflicted from participating. Industry sector expertise was an important factor in the selection of the firms invited to tender, given the regulatory complexities of the business. All three of the firms that participated demonstrated considerable experience of the utility sector and/or water sector and the industry experience of the key members of the audit teams demonstrated the same. A selection panel was established consisting of: the Chair of the Audit Committee; all members of the Committee; the Group Chair; the Group CEO, the Group CFO and the Group Financial Controller, thereby ensuring a wide range of views were taken into account and a considerable amount of financial expertise supported the Committee in the decision-making process. Each firm’s proposal consisted of a written tender document and face-to- face presentations. Their responses were evaluated by the selection panel against the following criteria, as set out in the RFP: • Audit approach and overall audit quality assurance. • Quality, experience of the lead partner, team and firm and their ability andtrack record of challenging management and delivering audit quality. • Approach to achieving a smooth audit transition, if relevant. • Service delivery, including value add from the audit. • Culture and reputation of the audit firm. • Performance during the proposal process. Proposals were assessed on these criteria with pricing being a secondary point of evaluation after the initial assessment. Outcome of statutory audit tender process Following the selection panel process, the Audit Committee met to review and discuss the bidders’ proposals, how these proposals met the assessment criteria, and a paper summarising the assessment was prepared, following which the committee made its recommendation that PricewaterhouseCoopers LLP (PwC) was its preferred candidate. The recommendation was approved by the Board on 21 st February 2024 . The Board accepted the Committee’s recommendation that PwC would be appointed as statutory auditor for the year ending 31 st March 2025, subject to shareholder approval at the Annual General Meeting in July 2024. There are no contractual obligations that restrict the Committee’s choice of auditor; the recommendation is free from third-party influence and no auditor liability agreement has been entered into. PwC were identified as the preferred candidate due to: the strength, experience and breadth of its team in relation to the industry, regulation and technology capabilities; PwC’s thorough consideration of the audit scope and approach and how innovation will be deployed to enhance audit approach and quality; PwC’s clear commitment to the transition process with advanced levels of planning in how the process would be managed to ensure audit quality; the proposed audit engagement partner and the entire team demonstrated a genuine enthusiasm for driving further audit quality; and demonstrated their capabilities to deploy technology to address key audit risk areas. As noted above, in reaching the assessment, the Committee considered the ranking of the firms before and after the consideration of pricing. In both scenarios PwC proved to be the preferred candidate. Colin Bates will be appointed as PwC’s audit engagement partner for the year ending 31 st March 2025, having shadowed EY during the 2023/24 auditprocess. Internal audit The internal audit activities of the Group are a key part of its internal control and risk management framework. At Group level there is a long-standing and effective centralised internal audit service, which supports the Committee in delivering its responsibilities and has continued to operate effectively. The internal audit charter was updated during the year to reflect the requirements of the new Global Internal Audit Standards. The Group Internal Audit Plan is set on a rolling six-month basis and was approved in March 2023 and September 2023, following a thorough review to ensure it provided adequate coverage over the Group’s key risks for the year ahead and was sufficiently flexible to respond to emerging risks. In developing the plan, account is taken of the principal risks, the activities to be undertaken by the External Auditor, and the Group’s annual and ongoing risk management reviews. This approach seeks to ensure that there is a programme of internal and external audit reviews focused on identified key risk areas throughout the Group. The Group Director of Risk and Assurance reported regularly through the year to the Committee on the outcomes and findings of internal audit activity. There were regular discussions, correspondence and private meetings between the Director of Risk and Assurance and the Committee Chair. The Committee continues to monitor the performance of the internal audit function as part of its annual assessment of the effectiveness of the function. As required by IIA standards, the next cyclical external review of the internal audit function will take place before the end of 2026/27 (the last having been undertaken in 2021/22). Fair, balanced and understandable assessment To enable the Committee to advise the Board in making its statement that it considered that the Company’s Annual Report to be fair, balanced and understandable (FBU) on page 174, the Committee applied a detailed FBU review framework that takes account of the Group’s well-documented verification process undertaken by management in conjunction with the preparation of the 2024 Annual Report. This was in addition to the formal process carried out by the External Auditor to enable the preparation of the independent auditor’s report, which is set out on pages 175 to 184. In preparing and finalising the 2024 Annual Report, the Committee considered a report on the actions taken by management in accordance with the FBU process and an FBU assessment undertaken by the Pennon Executive. This assisted the Committee in carrying out its own assessment and being able to advise the Board that it considered that the Annual Report taken as a whole is fair, balanced and understandable and provides the information necessary for shareholders to assess the Company’s position, performance, business model and strategy. Looking forward During the forthcoming year, the Committee will remain focused on the key areas of responsibility delegated to it by the Board, ensuring that standards of good governance are maintained and that appropriate assurance is obtained across all areas of the business. Particular focus will be given to the Group’s principal risks, internal control environment and approach to financial reporting, noting the volatility in the global economy. Developments in reporting responsibilities, including those recommended by the Task Force on Climate-related Financial Disclosures (TCFD), the consideration of climate risk in preparation of the financial statements and the changes in the UK Corporate Governance Code will be considered throughout the year. 141Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Audit, risk and internal control Risk management and the Group’s system of internal control The Board is responsible for maintaining the Group’s system of internal control to safeguard shareholders’ investments and the Group’s assets and for reviewing its effectiveness. The system is designed to manage rather than eliminate the risk of failure to achieve business objectives and can only provide reasonable and not absolute assurance against material misstatement or loss. An ongoing process for identifying, evaluating and managing the significant risks faced by the Group has been in place throughout the year and up to the date of the approval of this Annual Report and Accounts and was last reviewed by the Board at its meeting in March 2024. The Group’s system of internal control is consistent with the Financial Reporting Council’s (FRC) ‘Guidance on Risk Management, Internal Control and Related Financial and Business Reporting’ (FRC Internal Control Guidance). The Board confirms it applies procedures in accordance with the UK Corporate Governance Code and the FRC Internal Control Guidance, which bring together elements of best practice for risk management and internal control by companies. The Board’s risk framework described on pages 55 to64 of the Strategic Report provides for the identification of key risks, including ESG risks, in relation to the achievement of the business objectives of the Group, monitoring of such risks and ongoing and annual evaluation of the overall process. Details of the key risks affecting the Group are set out in the Strategic Report on pages 1 to 111. Key performance indicators are in place to enable the Board to measure the Company’s ESG performance on pages 42 to 44 and a number of these are linked to remuneration incentives on page 151. As part of the review evaluating the system of risk management and internal control under the Group risk management policy, all Executive Directors and senior managers are required to certify on an annual basis that they have effective controls in place to manage risks and to operate in compliance with legislation and Group procedures. This took place on March 2024. The Group’s processes and policies serve to ensure that a culture of effective control and risk management is embedded throughout the Group and that the Group is able to react appropriately to new risks as they arise. New and emerging risks are identified in further detail in the risk management section on pages 55 to 64. Code of Conduct and policies The Code of Conduct and related policies set out Pennon’s commitment to promoting and maintaining the highest ethical standards. Areas covered in the Code of Conduct and related policies include our impact on the environment and our communities, our workplace, and our business conduct. The Code of Conduct sets out the values and principles by which we operate and provides a framework for ethical business practices. It is further supported by several policies that guide our workforce and suppliers, so that we can identify and deal with suspected wrongdoing, fraud or malpractice, maintain the highest standards of compliance, and apply consistently high standards of ethics. We aim to maintain a culture that fosters the reporting of any concerns, and trust and confidence that we will act upon them. Our Code of Conduct and other key compliance policies can be found here: https://www.pennon-group.co.uk/about-us/policies Anti-financial crime framework The anti–bribery and corruption, anti-tax avoidance, and anti-money laundering policies were reviewed and consolidated (together with new guidance to reflect the provisions of the Economic Crime and Corporate Transparency Act 2023) into a new Board approved anti-financial crime policy in March 2024. The new policy includes guidance on Pennon’s zero tolerance approach to acts of bribery, fraud, money laundering and tax evasion. The Policy outlines the requirements of Group companies to comply with relevant legislative, ethical standards and best practice on preventing financial crime, and provides information and guidance to those working for and on Group’s behalf on how to spot ‘red flags’ that could indicate a risk of financial crime. The policy is in the process of being rolled out comprehensively into all parts of the Group, through the Company’s learning management platform to track review and record understanding; this process is complemented by online training for new joiners on the individual areas of financial crime and annual refresher training for all employees on the Code of Conduct (which incorporates anti-financial crime guidance) arranged by the Legal Compliance team. The Group ensures compliance with the policy in line with our risk-based approach by conducting ad hoc checks on completion of the mandatory training set out above, providing specific training to areas of potential higher risk (e.g. Procurement and Commercial & Estates), and carrying out detailed investigations into allegations of potential wrongdoing (whistle blows) received from employees, customers and suppliers. 142 Annual Report and Accounts 2024 « Pennon Group plc The potential consequences for colleagues and the Group itself are clearly set out in the policy as are the processes for raising concerns. Any breaches or failure to adhere to the Group’s strict standards of integrity and honesty will be subject to disciplinary action, up to and including dismissal from the Company. All employees are required to report any circumstances or any suspicions of fraud, bribery, corruption or other irregularities, either to a line manager or by using the Group’s confidential whistleblowing service Speak Up. The Legal Compliance team (in conjunction with the Internal Audit function and Group Tax team) created a revised financial crime risk assessment framework in April 2024 to incorporate the requirements of the Economic Crime and Corporate Transparency Act 2023. The framework includes an annual: • Combined business-wide bribery and fraud risk assessment process led by the Legal Compliance team. • Tax evasion risk assessment led by the Group Tax team. • Review of the money laundering suspicious activity report process led by the Head of Legal Compliance in conjunction with the Group Treasury team. The framework is complemented by the annual review of corporate policies (led by the Legal Compliance team) relating to financial crime prevention. These are presented to the Board for approval at their September meeting. These include: • Code of Conduct (including introductory message stressing the importance of compliance from Group CEO) • Gifts and Hospitality • Anti-Financial Crime Policy; and • Whistleblowing Policy and investigation process. Allegations of financial crime are reported to the Audit Committee together with investigation outcomes and details of any action taken, which are disclosed to our external auditors. There were no confirmed cases of bribery, corruption, fraud, or business ethics violations during the year. Training and communications Our comprehensive programme of training and internal communications continues with targeted messaging and interactive training sessions. This programme addresses the business’s key compliance risk areas and has been designed to increase resilience, heighten awareness, and promote a culture of doing the right thing. From 2024, colleagues will be required to complete refresher compliance training (focussed on the Code of Conduct which signposts to all Group policies) on a yearly basis to ensure that continuous knowledge and understanding of our policies are maintained. Whistleblowing policy – Speak Up The Speak Up service encourages employees and our suppliers to raise concerns about suspected wrongdoing or unlawful or unethical conduct, explains how any such concerns should be raised and ensures that employees and suppliers are able to do so without fear of reprisal. The Group’s whistleblowing policy, investigator training programme and investigation process were reviewed and reapproved in March 2024. The whistleblowing policy now reflects the Ofwat best practice recommendations published in November 2023 and specifically encourages the reporting of: • Endangering someone’s health and safety. • Anything that is against the law. • Stealing or fraud. • Corrupt or dishonest activity. • Damage to the environment. • Covering up wrongdoing. • Abuse of authority. • Intentionally misreporting to a regulatory body. • Bullying, harassment and/or victimisation. • Tax evasion of the facilitation of tax evasion. The Speak Up service comprises telephone and web-based reporting channels operated for Pennon by independent provider NAVEX Global. Following receipt of a report, the allegation will be triaged to assess if the issue is a personal grievance or has a wider public interest element, and an investigation started promptly if in the public interest to do so. The investigation process is overseen by the Ethics Management Committee and will be undertaken fairly, impartially, and thoroughly by appropriately trained investigators with strict confidentiality being maintained at all stages of the investigation. After each investigation, a confidential review is undertaken by the Head of Legal Compliance to identify any lessons learnt, or organisational improvements or training requirements. Other improvements identified are always acted upon, while ensuring the paramount requirement of operating a whistleblowing process that protects the identity of individuals and the independence and integrity of the process. Our whistleblowing process is designed to support our staff, reflect shared responsibility, promote a positive culture, provide unique insights and is central to our system of checks and balances. 143Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information ESG Committee report Iain Evans Chair of the ESG Committee The ESG Committee (the Committee) supports the Company’s ongoing commitment to environmental stewardship. Dear Shareholder I am pleased to report on the ESG Committee’s activities and achievements during 2023/24. Paul Boote resigned as Group Chief Financial Officer and as member of the Committee in December 2023, we are immensely grateful for Paul’s contributions to our ESG obligations throughout the years. I continue to be supported by an experienced Committee who focus on governing our ESG activity and disclosure and ensuring we continue to be a responsible business and creating a positive long-term impact on the environment and all our stakeholders and I’d like to thank them for their work and input thisyear. Our approach to ESG ensures that everything we do supports our commitment providing environmental stewardship and supporting our local communities and customers. A broad range of ESG topics were considered by the Committee during the year while fulfilling its duties in accordance with its terms of reference, which were also refreshed and approved during the year. The Committee closely monitored its wide range of ESG measures, targets and environmental KPIs alongside compliance and assurance activities, which showed strong performance throughout the year. A strategic leadership approach to areas of improvement, particularly in our energy usage in renewable energy generation, pollution and spills incidents was demonstrated, with remediation activities underway to ensure performances are stronger for 2024/25. Our strong progress on existing regulatory commitments and plans on our Group ESG targets, through to 2025, have been further identified in “Our Integrated Approach to ESG” on page 67, andthe key focus areas for the Committee in 2024/2025 are noted in the “Focus areas for 2024/25” below. Committee members Date of appointment to the ESG Committee Attendance Iain Evans September 2018 Gill Rider September 2012 Susan Davy March 2018 Jon Butterworth July 2020 Dorothy Burwell December 2022 Paul Boote 1 July 2020 1. Paul ceased to be a member of the Committee following his resignation on 31 st December 2023. Role of the ESG Committee • Review the policies, management, initiatives and performance of the Group with respect to the environment, workplace policies, Group governance and corporate policies relating to responsible and ethical business practices, the role of the Group in society and customer service and engagement. • Review the overarching environmental performance of the business, ensuring a focus on key areas of improvement. • Review the actions of the Group to determine the suitability of theworkplace environmental policies and practices of key suppliers andcontractors. • Review the extent and effectiveness of the Group’s external reporting of sustainability performance and its participation in relevant external benchmarking indices. • Regularly report to the Board. • Advise the Audit Committee of any material non-financial risks. The key successes of the Committee’s focus for 2023/24 • Reviewed the external 2023 ESG Assessment scores and approved the work being undertaken to improve these. • Successfully achieved the majority of 2023/24 ESG targets. • Successful progress made against the majority of environmental KPIs, including WINEP delivery, biodiversity and achieving 100% EDMs installations. • Approved the creation of the environmental advisory panel for PR24. • Successfully achieved the framework for migration to new capital delivery for PR24. • Carried out deep dive reviews on supply chain processes for the Company. • Continued delivery of TCFD and TNFD recommendations including detailed appraisal of transition risks and opportunities and scenario analysis. • Preparation post the disbanding of TCFD for the new IFRS S2 climate- related disclosures. 144 Annual Report and Accounts 2024 « Pennon Group plc The Committee engaged in a deep dive on how we measure ESG performance through our supply chain processes and ensured that sustainable principles and practices are inherent in the Group’s activities. Following this session, the Committee endorsed that, as part of its ESG improvement programme, supplier ESG measures be assessed against stakeholder, regulatory and investor requirements to ensure alignment with our sustainability ambitions. The Committee approved the creation of an environmental advisory panel in September 2023, as part of the PR24 submission. The independent panel will provide expert and independent advice, help challenge our environmental activities, and demonstrate our commitment to focusing on environmental outcomes, which are of great importance to our stakeholders. In line with our TCFD requirements, we have disclosed climate-related financial information on pages 78. These disclosures evidence our strategy to reduce emissions within our operations and through our supply chain to achieve Net Zero by 2030. The Committee had oversight of our climate related governance, ensuring that climate change management was integrated into our principal risks. This Annual Report provides an integrated assessment to show how a responsible approach to sustainability helps us to balance the immediate and longer-term needs of society with the delivery of sustained commercialsuccess. ESG performance The ESG Committee continues to assess performance against a range of challenging targets for the Group, set as part of the business planning process. The Committee reviewed and monitored 2025 targets ensuring that the metrics, ODIs, Operational Service assessments and ESG targets continue to align with the strategic themes identified in the Committee’s materiality assessment. The Committee agreed that the targets for 2024/25 should be published in this Annual Report on page 68. In addition, the ESG Committee provides assessment and oversight of South West Water’s performance against sustainability targets that are core to the successful delivery of its five year business plan. This is consistent with Ofwat’s requirement for independent governance of the regulated business. As at 31 st March 2024, Pennon achieved 15 of our 16 targets for 2023 and are currently on track to meet our 2025 targets. Whilst we have continued to invest in solar generation, energy usage has continued to be higher than the baseline (driven by increased pumping and treatment to respond to the extreme wet weather this year). This has resulted in generation as a proportion of total usage being lower than targeted for the year.. Enhanced reporting and assurance With a growing focus on ESG reporting, we are increasing our 2024 reporting suite and providing enhanced disclosure through our SASB disclosure which can be found on page 74, and our ESG databook which is available to view at www.pennon-group.co.uk/sustainability. Pennon’s ESG reporting is integrated throughout the strategic report and specifically in the following sections: Section Page Chair’s letter 4 Chief Executive Officer’s review 5 Business model 22 Strategy overview 4 Key performance indicators 42 Environmental performance 23 Social performance 25 Governance performance 112 Stakeholder overview 126 Our people strategy 25 Our operations 32 Other related reporting including our Gender Pay Gap report, Climate Change Adaptation Report and Net Zero plan can be found on our website www.pennon-group.co.uk/sustainability. Pennon’s ESG performance and reporting has been assured by DNV, an independent management consultancy specialising in technical assurance in the utility sector. DNV’s method of assurance includes testing the assumptions, definitions, methods, and procedures that are followed in the development of data and the auditing thereof to ensure accuracy and consistency. The assurance statement can be found on our website at www. pennon-group.co.uk/sustainability. Certain disclosures within this Annual Report that relate to the sustainability performance of South West Water and Bristol Water have been subject to an independent audit of regulatory data conducted by Jacobs. DNV has reviewed the consolidation of these into total Pennon data where stated, but not their preparation. Jacobs are engaged to independently audit South West Water’s and Bristol Water’s technical (non-financial) data relating to our Outcome Delivery Incentives published in its Annual Performance Report (APR); this includes all regulatory targets, including a suite of environmental performance indicators. This year, Turner and Townsend have conducted an independent audit of other non-financial data, also included in the APR. This includes allSouth West Water regulatory targets, including the suite of environmental performance indicators. Jacobs provide a report on this audit within SouthWest Water’s APR. Similarly, Turner & Townsend conduct an independent audit of Bristol Water’s technical (non-financial) data, alsopublished in theAPR. Benchmarking It’s important to us to ensure we are regularly benchmarked against the expected industry standards. This ensures we are continuing to provide up to date disclosure for our stakeholders. Certain leading indices assess companies on their disclosures relating to stringent environmental, social and governance criteria, and their capacity to capitalise on the benefits of responsible business practice. Pennon is a constituent within the FTSE4Good Index, Sustainalytics, CDP Climate Change, S&P Global CSA, and a number of other leading external ESG assessments. FTSE4Good and similar leading indices are designed to facilitate investment in companies that meet globally recognised corporate responsibility standards. Our latest external assessment scores as at 31 st March 2024 are included on page 67 with improvements and maintenance of our strong position seen in all of the assessments. An action plan to enable the Group to become asignatory of the UN Global Compact, the largest corporate sustainability initiative is underway, and next steps in becoming SBTi verified have beencompleted. Focus areas for 2024/25 • Embed the results of our extensive materiality assessment due to be completed in 2024 to set our future environmental targets. • Review our ESG assessments in line with incoming legislation - UK Sustainability Disclosure Standards (UK SDS). • Engage in diverse deep dive sessions across the ESG areas. • Further integration of ESG across the entire Group, including supply chainmeasures. • Expansion of community impact evaluation and reporting. • Review performance on how the company is fulfilling its purpose and itsexternal ESG benchmarking. • Undertake Committee governance matters such as its rolling calendar of agenda items, annual Committee evaluation and examination of Committee’s terms of reference. • Preparation for the disbanding of TCFD and the new IFRS S2 climate related disclosures.

Role of the Health & Safety Committee • Review and challenge to support the Board and Executive on all matters connected to Health and Safety. • Review the extent and effectiveness of the Group’s reporting of health and safety performance and compare to external benchmarks. • Regularly report to the Board. • Advise the Audit Committee of any material non-financial risks. The Committee’s focus for 2023/24 During the year, the Committee considered a wide range of matters in the course of fulfilling its duties in accordance with its terms ofreference: • Half yearly comprehensive reviews of the Group’s Health &Safetyperformance. • A review of the tactical interventions to deliver in year improvements inincident reduction. • A review of the HomeSafe 2025 strategy and plans to increase robustness in Process Safety. • A review and challenge of high potential near-miss events to ensure themes are identified and pragmatic solutions implemented. • Visiting operational sites to engage with front-line colleagues and the wider Health and Safety teams. Committee members Date of appointment to Health & Safety Committee Attendance Jon Butterworth November 2020 Iain Evans November 2020 Dorothy Burwell December 2022 Susan Davy November 2020 Paul Boote 1 November 2020 1. Paul Boote stepped down from the Board on 31 st December 2023. Dear Shareholder I am pleased to provide an update on the Health & Safety (H&S) Committee’s activities during the year. I believe the key to ensuring we keep employees safe and well in the workplace, is through empowering everyone to take responsibility for the health, safety and wellbeing of each other and for themselves. Simply put, it’s about culture, leadership and accountability. This underpins the HomeSafe strategy and has been a welcome focus over the last 12 months. A personal highlight for me this year, as Chair of the Committee, was celebrating Pennon Water Services’ fourth lost time injury free year (employee and agency). This is a great achievement that highlights the hard work of both the health and safety teams and the Pennon Water Services’ employees who embed the HomeSafe values into their work every day. Our dedicated Board Committee, focused purely on H&S, ensures the Board continues to support our HomeSafe strategy and the Group’s vision that everyone goes home safe every day. We continue to strive to be a leader of H&S by 2025 in our sector, and leadership from the top is critical. The Board has dedicated time to visit operational sites, discuss and review performance, offer support, encourage learning, and meet department and site leaders and employees from across the business. Reviewing the Group’s health and safety performance, effectiveness of health and safety policies and procedures, including the continued roll-out of the HomeSafe strategy, has been core, with significant improvements already noted. I was delighted that the Committee was able to support the HomeSafe Live event this year. The event, which changed formats from previous years, was brought to life with engaging workshops delivered over six days at six different venues within the South West. The interactive workshops had core health and wellbeing messages featured throughout and allowed employees to engage directly with senior leadership. Importantly, the Committee reviews deep dives of High Potential Incidents with a particular focus on lessons learned, getting to the root cause, encouraging a learning mindset. These reviews highlight the improvements in culture, leadership and accountability through open and honest investigations seeking to learn and improve and deliver pragmatic solutions. Jon Butterworth Chair of the Health and Safety Committee 146 Annual Report and Accounts 2024 « Pennon Group plc Building on the first Pennon Group H&S conference I attended last year, the Group held two more conferences through the year building on the themes of Taking Ownership. These events were led by the Senior Leaders across the Group demonstrating personal commitment and leadership in health and safety. Over 2,300 colleagues attended, taking time to focus solely on their role in supporting our HomeSafe ambitions. Along with other elements within the HomeSafe plan, these events have supported a tangible increase in overall ownership of HomeSafe and have undoubtedly contributed to the step change reduction in incidents this year. H&S Committee composition All Board members are attendees and served throughout the year, with support from the Group Chief People Officer and Pennon’s H&S Director. Reporting In addition to the regular Board report by the Group Chief Executive Officer, detailed performance is reviewed quarterly by the Executive team, and six- monthly by this Committee, focusing on performance, benchmarking, and lead activities such as leadership and engagement, hazard rectification, asset health, critical safety controls and working environment. Leaders have taken accountability and driven significant improvements in the lead areas. This has supported the step change reduction in outcome metrics, with the Lost Time Injury Frequency Rate (LTIFR), employees and agency, excluding contractors, reducing through the year by 50%. The HomeSafe strategy continues to drive improvements and is regularly reviewed to ensure it drives us towards our 2025 aims, and beyond. The Committee will continue to review and challenge plans and performance to support our HomeSafe ambitions, with a detailed roadmap to 2025 built on six key pillars. Jon Butterworth Chair of the Health and Safety Committee 20 th May 2024 HomeSafe strategy The Group’s flagship H&S programme, HomeSafe, continues to provide the framework for driving significant improvements in all health and safety activities and impacts.

Being Resilient Read more on pages 28. 147Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information 147Pennon Group plc » Annual Report and Accounts 2024 Remuneration Committee report The role of the Remuneration Committee is to set and implement executive pay ina fair and socially responsible manner. Role of the Remuneration Committee • Ensure remuneration is aligned with the Group’s strategy and reflects the values of the Group. • Determine the Remuneration Policy to ensure it remains appropriate, considering shareholders’ views and best practice, supports attraction, retention and motivation of Executive Directors . • Advise the Board on the framework of executive remuneration for the Group. • Set the remuneration level for the Chair, the Executive Directors and senior executives of the Group and review the remuneration arrangements of the wider workforce. • Approve the design and determine targets for any performance-related pay schemes. • Determine the appropriate outturn of any incentive arrangements. The Committee’s focus for 2023/24 • Consider the remuneration and terms of engagement of the Executive Directors, senior executives and Chair of the Group and the remuneration of the wider workforce. • Determine the appropriate long-term incentive arrangements for the Group over the next 3-5 years engaging with stakeholders as appropriate. • Determine targets that remain stretching, relevant to the Group’s strategy and values and reflect best practice and wider stakeholders’ views. Committee members Date of appointment to Remuneration Committee Attendance Claire Ighodaro July 2020 Iain Evans September 2018 Loraine Woodhouse December 2022 Dorothy Burwell December 2022 Dear Shareholder I am pleased to present the Directors’ remuneration report for the year ended31 st March 2024. The Committee’s approach to Executive remuneration has always been underpinned by doing what is right for our customers, investors, wider stakeholders, the communities in which we operate and the environment. Our values and integrity are reflected in the decisions we make, and in focusing incentives on what matters most as a socially responsible business and providing transparency on outcomes. Whether you are a shareholder, a customer or the regulator, we all have a shared interest in ensuring water companies are performance driven, sustainable, financially resilient, mindful of our impact on the environment and able to make the substantial capital investment required in infrastructure in order to ensure the long-term viability of the sector. We continue to believe that the sector needs to be able to attract the high-quality talent required to lead large, complex organisations, by incentivising and rewarding management teams fairly forthe outcomes achieved. Claire Ighodaro Chair of the Remuneration Committee We are mindful of the views of the public and the regulator. Over the course of the year, I have engaged with Ofwat and sought feedback on our approach as well as contributing to wider sector considerations as to how executive remuneration can evolve to ensure that all stakeholders can see transparency and clarity in decisions on performance related pay, and I know from my conversations with shareholders that this is a shared ambition too. Turning to the performance in year, we have delivered record levels of investment spend as we focus on underpinning our operations to deliver improved performance and in driving cumulative RCV growth of 65% since the start of K7, along with record support for customers of £100 million. Our acquisition of SES Water in January 2024 was an important milestone in our continuing strategy of growth within the water sector. We are fast- tracking through the Competition and Markets Authority’s review of the acquisition, and we look forward to welcoming a further 470 colleagues to theGroup, securing jobs, as well as providing financial resilience and improved investment for the c.750,000 people we serve in Sutton and East Surrey. Our strong shareholder support continues to be demonstrated by the over-subscription of our equity raise conducted in connection with the acquisition. The development and excellent customer service of the B2B retailers, Pennon Water Services and Water2Business, has doubled profitability and market share. Our ambitious business plan for the regulatory period 2025-30 was submitted to Ofwat on 2 nd October 2023, detailing our largest ever investment of £2.8 billion in the region. The plan creates 2,000 jobs providing valuable careers, supporting customers and communities across the South West and the wider supply chain. Our customers, many of whom are also shareholders through our unique WaterShare+ scheme, engaged in the development of our plans, giving feedback and confirming what matters mostto them now and for the future. 148 Annual Report and Accounts 2024 « Pennon Group plc Our performance over the last financial year has continued to deliver outperformance on base returns, enabling reinvestment that will improve service quality over the longer term. Although our profit before tax and earnings per share results reflect the impact of exceptional levels of UK inflation on our debt instruments, the underlying financial results remain robust as demonstrated by EBITDA of £338.3 million. We also remain on track to deliver our ambitious Net Zero programme by 2030 with our £59 million investment in Pennon Power, on track to deliver 135 GWh annual storage. Our investments in water storage with the opening of two mini reservoirs have contributed to the achievement of 100% strategic reservoir capacity in the year and ahead of target. However, we recognise that there remains scope for improvement in our wastewater services across Devon and Cornwall as we work towards our stretching targets, and as weather impacts and increased flows have affected the headline performance of pollutions and the use of storm overflows with a re-profiled delivery plan to achieve 4-star rating for 2025. Wider Workforce Remuneration We are committed to ensuring remuneration for our front-line colleagues is competitive, understanding that this is the right priority when the financial landscape is challenging. We are proud that we have been an accredited Living Wage Foundation payer since 2021, and in practice we had aligned our pay rates to these recommended levels for some time prior to accreditation. Our strong 2023 pay settlement ensured we remained in this position across the Group despite both Living Wage Foundation rates and National Minimum Wage rates increasing substantially. The 2024 pay award reflects our most progressive pay award to date, continuing to focus on front line roles with an increase valued at 4.6% inclusive of 1 day additional holiday for the majority of colleagues. Those on salaries above £50,000 will receive an increase valued at 4.4% inclusive of holiday. We are proud that our employees will earn a minimum of £12.50 per hour, which not only aligns with, but exceeds the real living wage by almost £1,000 annually, underscoring our dedication to being an employer of choice. During 2023/24 we updated our Group Reward Principles to reflect the broader strategy, evolving composition of the Group and recent acquisition activity which has expanded our workforce across multiple locations. Key areas of focus included the addition of new Group Values, strengthening wellbeing and incorporation of greater employee flexibility either in work patterns or in choices of lifestyle benefits. We also took time to reflect on our annual bonus for colleagues, ensuring clear line of sight between their objectives and the Group strategy, our customers and their communities. Our annual bonus plans allow our colleagues to share in the Group’s success. We also offer highly competitive retirement benefits to our employees, which include additional life assuranceprotection. Our HMRC-approved share schemes continue to be popular with c.50% of colleagues participating in either the ShareSave or Share Incentive Plan. We have once again provided expanded disclosure on our approach for the wider workforce, and this is set out on page 155. Remuneration Policy review Our Remuneration Policy was approved by shareholders at the AGM in July 2023, receiving strong shareholder support of 93.6%. As flagged in last year’s Directors’ remuneration report, following the AGM we undertook a thorough review of our pay structures in the context of the recent business plan submission required by Ofwat and our strategic priorities, with a focus on ensuring the approach to pay continues to drive delivery of the long-term strategy. As part of this process, we consulted with our largest shareholders and other stakeholders on potentially moving to restricted stock as the primary long-term incentive vehicle for senior executives. Whilst there were a range of views from investors during consultation, we were pleased to note that the majority of our major shareholders were supportive of making this change. However, it was also very apparent that pay in the water sector continues to attract significant external scrutiny and guidance from the regulator continues to evolve. In this context we ultimately concluded that this was not the right time to make wholesale changes to our pay model. We will continue to consider the approach to executive remuneration over the coming years, taking into account our business strategy and the evolving views of our various stakeholders, including Ofwat. I would like to thank investors who provided feedback during the consultation process. We will continue to appropriately engage with ourmajor investors regarding any potential changes in future years. Although we are not making significant changes to pay at this juncture, the Committee remain acutely aware of the challenges with recruiting and retaining senior talent in the sector. Incentive Outcomes Following guidance provided by Ofwat, we have taken steps to ensure that performance-related pay outcomes for the executive directors are funded atthe Group level and will therefore not be funded by customers. As well as considering formulaic results against targets, the Committee also review outcomes in-the-round, utilising our holistic performance assessment framework to ensure that outcomes are considered from a number ofperspectives. For 2023/24, we increased the portion of the annual bonus linked to outcomes for our customers, communities, and the environment to 60% consistent with regulator guidance with the balance based on a target linked to financial resilience. Further changes to the detailed assessment were made to capture feedback provided by Ofwat. The Committee carefully considered the formulaic outcome of the annual bonus of 46.5% of maximum and debated this at length. After applying the Committee's discretion framework in respect of South West Water's environmental and pollution performance, it was decided to reduce the formulaic outturn to 38.5%. Furthermore, in recognition of the current external environment, the Committee determined that no bonus would bepaid to Executive Directors in respect of the year. This was consistent with management’s recommendation for a zero bonus outturn. Further details of incentive outcomes are set out in the main body of thereport. 149Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Board changes As previously announced, Paul Boote stepped down as CFO and from the Board on 31 st December 2023, as part of a planned relocation away from the South West. Paul’s departure terms are consistent with the shareholder approved Remuneration Policy. Further detail is set on out on page 163. The Board were delighted to appoint Steve Buck as Group Chief Financial Officer. Steve joined the Group and was appointed to the Board in November 2023, assuming the role of CFO effective 1 st January 2024. Steve is a proven CFO with considerable experience in the regulated utilities and energy sector, and a demonstrable track record for driving performance. Steve was appointed on a salary of £470,000, modestly positioned 3.6% higher than his previous salary within the water sector. Whilst we recognise that this represents a material increase relative to the previous incumbent, his uplift in salary is substantially lower than typical premia paid to executives when changing roles. Steve’s salary in his previous role was positioned between the median and upper quartile of FTSE 250 reference points. Taking into account sector practice, the market pay levels observed during the recruitment process, and most importantly Steve’s experience, the Committee was comfortable that the salary had been appropriately positioned. Other ongoing elements of Steve’s package are in line with the Remuneration Policy. Steve was also granted buyout awards in connection with awards forfeited upon leaving his former employer on a broadly like-for-like basis. Whilst all of these awards were due to be delivered in cash, it was considered appropriate to deliver a portion of these in Pennon shares to provide alignment with shareholders in line with best practice. Full details of Steve’s joining arrangements are set out on page 162. Implementation for 2024/25 For 2024/25 both the Chief Executive Officer and Chief Financial Officer have been awarded salary increases of 4%. This is below the average increase awarded to the wider workforce, where increases ranged from 4% to 4.2%, with increases at the upper end of this range focused on our lowest earners. With an additional day of holiday, overall value ranges from 4.4% to 4.6%. In light of evolving Ofwat guidance the Committee is currently undertaking a review of targets for variable incentives. Consistent with the approach taken in prior years, the annual bonus will seek to include metrics that suitably capture long-term financial resilience as well as metrics which are directly linked to matters of importance for our customers, communities and the environment. Annual objectives are deemed to be commercially sensitive, and consistent with prior years full details of the metrics and targets will be disclosed in next year's Directors’ Remuneration Report. As part of the 2023 review of the Remuneration Policy, the performance criteria for the LTIP were refined in order to incorporate an element directly linked to Water Quality and the Environment. While the current intention is to maintain a broadly similar structure for the 2024 awards, the detail is yet to be finalised as the Committee is keen to ensure that the targets suitably reflect the objectives for the next regulatory cycle, the acquisition of SES Water and evolving Ofwat guidance. Once finalised, we intend to publish the targets on the Company’s website In line with the approach for 2023/24, performance-related pay outcomes for the executive directors will be funded at Group level and will not be funded by customers. The Remuneration Committee remains committed to implementing a measured and responsible approach to executive pay, whilst also recognising the challenging roles of our Executive Directors. As a Committee we are acutely aware of our responsibility to do the right thing and this has been reflected in decisions made and voting support at previous AGMs. We look forward to our continued dialogue with shareholders and your continued support at the 2024 AGM.

A summary of the policy is set out below alongside detail on how we intend to implement the policy in 2024/25. Fixed pay Salaries generally reviewed annually, with increases effective 1 st April. Benefits provided are consistent with the market and level of seniority to aid retention of key skills to assist in meeting strategic objectives. Pensions are aligned with maximum rate available to wider workforce. Salary Salary increases of 4% effective for FY24/25 for Executive Directors. Increases are in line with the average increase valued between 4.4% and 4.6% inclusive of additional holiday for the wider workforce. Salaries from 1 st April 2024: Group Chief Executive – £511,290 Group Chief Financial Officer – £488,800 Benefits, including pension-related benefits Benefits currently include the provision of a company vehicle, fuel, health insurance and life assurance. Executive Directors pension-related benefits are in line with the maximum rate available to the wider workforce (10% of salary). Annual bonus Maximum bonus potential is 125% of base salary. Normally 50% of any bonus is deferred into shares released after three years. Malus and clawback provisions apply. FY24/25 – Continued strong link to customer, communities and the environment In light of evolving Ofwat guidance the Committee is currently undertaking a review of targets for variable incentives. Consistent with the approach taken in prior years, the annual bonus will seek to include metrics that suitably capture long-term financial resilience as well as metrics which are directly linked to matters of importance for our customers, communities and the environment. Annual objectives are deemed to be commercially sensitive, and therefore full details of the metrics and targets will be disclosed in next year's Directors’ Remuneration Report. Long-term incentive plan (LTIP) Maximum annual award is 150% of base salary. 3 year performance period, two-year holding period. Malus and clawback provisions apply. 2024 LTIP – Continued strong link to customer, communities and the environment As part of the 2023 review of the Remuneration Policy, the performance criteria for the LTIP were refined in order to incorporate an element directly linked to Water Quality and the Environment. While the current intention is to maintain a broadly similar structure for the 2024 awards, the detail is yet to be finalised as the Committee is keen to ensure that the targets suitably reflect the objectives for the next regulatory cycle, the acquisition of SES Water and evolving Ofwat guidance. Once finalised, we intend to publish the targets on the Company’s website. Shareholding requirements During the course of their tenure, Executive Directors are expected to build up a shareholding equivalent to 200%ofsalary. Departing Executive Directors will normally be expected to hold 200% of salary (or actual relevant holding, if lower) on departure, with the guideline reducing to 100% of salary after 12 months. 152 Annual Report and Accounts 2024 « Pennon Group plc Annual report on remuneration Oversight of Remuneration for the Wider Workforce The Remuneration Committee considers oversight of remuneration for the wider workforce as a key element of its remit and considers this when making decisions regarding remuneration for the Executive Directors. The Committee reviews a report on employee remuneration twice a year, either through a pay dashboard, which contains information on elements of financial and non- financial reward, the wider labour market, demographics and pay statistics across the organisation or through a subject specific paper. This detail provides important context to ensure that a consistent approach is adopted across the Group workforce including the Executive Directors. Developments in the financial and non-financial elements of the employee proposition are reviewed regularly, as well as share scheme participation and emerging reward trends. The Committee reflects on the position of our gender and ethnicity pay. Feedback to the Committee from employees is through RISE - our employee engagement forum through the Executive Directors on matters concerning remuneration arrangements. Our Reward Strategy and Approach for the Wider Workforce Our well-established People Strategy across the Group is centred around talented people doing great things for customers and each other and creating the best place to work. The Reward strategy and framework which was established in 2019 has been reviewed and updated during 2023/24. The updated framework reflects our changed Group composition, our latest business strategy and plans and changing employee expectations. The new Group values (see page 154) are incorporated. The framework will continue to set our approach for future developments in the reward landscape for colleagues. Pennon’s Group Reward Strategy continues to have three aims: Aim 1 Ensure reward decisions will support: • Our business strategy for delivering to customers and communities, and promoting long-term sustainable growth • Our People strategy and values • Our alignment to stakeholder expectations (e.ginvestors and regulators) Aim 2 Ensure the reward package offered toemployees is: • Designed and delivered fairly • Set up to enable the business to attract and retain the talent that it needs to be successful • Supports employee engagement and motivation • Allows employees to hare in Group success Aim 3 Clearly communicate to relevant stakeholders our employee reward and recognition principles and framework Rewarding our colleagues Salary increases for wider workforce As in 2023, we have focused our pay spend on those colleagues who have needed most support during the cost-of-living crisis. The 2024 pay award continues to focus on front line roles with an increase valued at 4.6% inclusive of 1 day additional holiday for the majority of colleagues. Those on salaries above £50,000 receive an increase valued at 4.4% inclusive of holiday. We are proud that our employees will earn a minimum of £12.50 per hour, which not only aligns with, but exceeds the real living wage by almost £1,000 annually, underscoring our dedication to being an employer of choice. For colleagues covered by collective pay bargaining, the award remains subject to ballot. During the year, we have completed a pilot of new working patterns in our drinking water function. This has been designed with our colleagues and union representatives to enable teams to benefit from a greater level of guaranteed pay whilst providing the business with more pro-active resource availability and less dependence on call out arrangements which can be disruptive to family life. Wewill continue to evaluate work patterns for the mutual benefit of customers, colleagues and operational needs during 2024. Wider workforce bonus arrangements All colleagues across the Group are eligible to participate in variable pay schemes. Senior bonus arrangements follow the model applied to the Executive Directors for their annual bonus incentive. Forthe wider workforce, bonus arrangements were reviewed in 2023/24 with a new scheme taking effect from 1 st January 2024. The new scheme has been constructed to reflect stretching targets which support delivery of our Business Plan for 2025-2030, focusing on water quality and resilience, storm overflows and pollution, our net zero agenda and customer service and affordability. The scheme maintains a measure for our imperative of all colleagues going HomeSafe each and every day. Financial wellbeing and wider benefits We offer a comprehensive range of benefits which have been extended over the past two years to include the roll out of a financial well-being and education partner for colleagues and their families. This includes an ill- health income protection policy which has provided support to a number of colleagues in 2023/24. We continue to operate a range of discounts, green initiatives and services to enhance our employeeproposition. Saving for the future We know that our colleagues value our responsible approach to pension contributions. We are pleased that despite the cost-of-living crisis, 95% of colleagues continue to participate in the defined contribution schemes. Our ShareSave scheme was again launched in 2023, continuing to support our belief that employees should have a stake and say in the business. TheShareSave sits alongside our evergreen Share Incentive Plan providing employees with monthly share purchase from pre-tax salary. The 2023 ShareSave scheme received strong support from our colleagues and we look forward to extending this and the Share Incentive Plan (SIP) to colleagues in South East and Surrey Water at the earliest opportunity. We have seen strong growth in participation in the SIP this year of c. 30%. In line with our scheme rules, shareholder approval will be sought at the 2024 AGM for the continued operation of our HMRC-approved schemes. Living Wage Foundation We continue to pay above the Living Wage Foundation rates for all roles excluding those colleagues who are on our apprenticeship arrangements. Our accreditation as a Living Wage Foundation employer has been maintained since 2021. We continue to focus our pay spend on lower paidroles. Wider workforce remuneration dashboard In accordance with the 2018 UK Corporate Governance Code, the Committee reviews the level of information provided on pay matters in the wider organisation. The Wider Workforce Remuneration Dashboard provides the Remuneration Committee with an overview of the approach to pay across the Group, supplemented with topic specific papers: • Helps support the Committee in reviewing workforce remuneration andrelated policies which continually evolves to provide greater insight • Provides an overview of pay arrangements across the business and key statistics on pay in different areas of the business • Updates on progress on our Reward Strategy implementation • Has oversight of the wider remuneration landscape to provide external context and industry specifics to inform on our benefits • Provides information on workforce demographics, gender pay, pay ratios, pension and benefits and incentive outcomes indifferent areas. The Committee intends to keep the content of the dashboard under review to ensure it remains suitable. 153Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Remuneration Committee report continued Our Group People Strategy We have an approved people strategy which outlines our priorities and aspirations.

Bethe future. 154 Annual Report and Accounts 2024 « Pennon Group plc Our Reward framework supports our People Strategy: Pillar Highlights Base pay The Group’s overarching principles for basic pay are as follows: • Base pay should reflect the level of skills, responsibilities and accountabilities of the job, plus the market and region in which the business area operates. • We should maintain a market competitive edge to attract and retain talent. Market benchmarking against recognised surveys isconducted regularly. • We should maintain our status as an accredited Real Living Wage Employer, guaranteeing base pay at or above the Living Wage Foundation rates. • We should review pay annually with any resulting award being subject to affordability and business performance. • We should ensure all roles are mapped to a pay band and publish the broad pay bands by work level on the Company’s intranet annually from 2024. • We should engage with RISE, the WaterShare Customer Panel and Recognised Trade Unions on pay decisions. • We should undertake equal pay and gender/ethnicity pay analysis from time to time to ensure we comply with current equality legislation and provide equal total reward opportunities for roles of equal value. Variable pay The Group operates variable pay schemes, including annual bonus arrangements and all employees and temporary workers are eligible to participate. Throughout bonus schemes, there is strong correlation in the targets, to align the whole organisation on goals linked to customer, communities and the environment. The maximum bonus levels are based on seniority and level of responsibility. At leadership level a portion of the bonus is deferred into shares for three years. Long-term incentive share awards are available to senior executives and Executive Directors, consistent with market practice. Our front- line teams receive overtime, call-out and standby payments, ensuring that when workloads are high, employees are fairly compensated. We remain mindful of the need to balance working hours, customer demand and available resource against the health, safety, wellbeing of our colleagues and following a successful pilot earlier in the year, our overarching principles on variable pay are as follows: • Provide every colleague with the opportunity to earn an element of variable reward using appropriate mechanisms for different colleague populations, as agreed by each business area. • Have clear communication on rationale, purpose, performance measures, pay-out calculation and other rules for the variable pay schemes, to ensure colleagues fully understand their total reward opportunities. • Ensure the performance measures included in the balanced scorecard are aligned to our business strategy, values and take into consideration the views of shareholders, customers, regulators and other key stakeholders. • Encourage colleagues to have share ownership delivered through variable pay. • Remuneration Committee or relevant Executive Committee can apply appropriate discretion to bonus outturn, considering the ‘how’ as well as the ‘what’. Saving for thefuture We offer highly competitive retirement benefits to our employees, which include additional life assurance protection. Membership of the Group pension scheme remains high with a 95% participation rate in our Defined Contribution (DC) scheme. As part of our Saving for the Future, all employees can participate in our HM Revenue and Customs-approved ShareSave and Share Incentive Plan, with a strong emphasis on employee buy-in and ownership. We look forward to extending eligibility to our South East and Surrey colleagues at the earliest opportunity. Not only do our share schemes provide a mechanism for sharing in the long-term success of the Group but mean that colleagues and customers have a say and stake in the business. Our overarching principles on Saving for the Future are as follows: • Provide every colleague with the opportunity to build up share ownership. • Clearly communicate and promote the existing share schemes to ensure maximum participation. • Ongoing exploration of HMRC-approved tax advantaged share scheme opportunities for broader offerings. • Provide every colleague with the access to our Defined Contribution pension scheme with the choice of employee/employer contribution levels. • Provide company matching in our Defined Contribution pension scheme to further support our colleagues saving for retirement. • Provide access to a fully interactive pension administrative platform and drop in sessions to ensure employees understand the offering and implications to make informed decisions. • Comply with the government required pension enrolment requirements. Benefits We operate a range of benefits of which the majority are available to all colleagues. These are selected for their ability to enable colleagues to get the best value from their salary such as discounts, to ensure a work life balance which supports both family life and outside interests through generous holiday entitlements or those designed to bring financial security such as income protection or life assurance. A range of advisory services are available to support colleagues on occasions where additional support is needed, including financial support, health and wellbeing, legal advice and a range of employee led support groups. From time to time, there may be necessary exceptions that apply to our core benefits, reflecting TUPE transfers or preserved contractual benefits. The principles for our benefits are as follows: • Operate a set of core Group-wide benefits for all colleagues, and a wide range of other additional offerings to enable colleagues select the most appropriate benefits tailored to their needs. • Ongoing evaluation of the effectiveness of the benefits offering, ensuring we take full advantage of our Group-wide purchasing power with benefits providers, and we are aligned with our Fair Tax Strategy and HMRC guidelines. • Actively engage with employees to understand their needs to continue shaping our benefits proposition. • Adopt technology to enable easy access to our benefits from home or work. • Continue to focus on developing our wellbeing and flexible working provisions, and explore additional benefits provision opportunities to support our broader ESG agenda (e.g. green voluntary benefits, volunteering days etc). 155Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Remuneration Committee report continued Gender and Ethnicity pay reporting We recognise our duty to contribute positively to society by cultivating an environment that promotes social mobility, prioritises diversity and inclusion, and ensures equitable treatment for all employees. Our aspiration is to become the Employer of Choice across our region, where trust is paramount, and every individual is valued for their contributions. Transparency lies attheheart of our commitment to diversity and inclusion. Reporting serves as a vital instrument in our journey towards openness, allowing us to candidly assess the gender and ethnic diversity within our workforce. Moreover, it enables us to share the proactive measures we have implemented and will continue to pursue to enhance diversity across all levels and roles within our organisation. We understand that fostering an inclusive workplace is imperative not only for attracting talent but also for retaining our valued colleagues and because it is the right thing to do. During 2022/23, in line with our Change the Race Ratio commitments, we voluntarily published our Ethnicity Pay Gap data for the first time. The results reflect our journey in building representation of ethnic minority groups and gender diversity across Pennon, noting that the South West, where a large proportion of our business is based, has a lower diversity mix than other parts of the UK. Our ethnicity pay gap is 0.17%. Across the Group we have been working hard to attract a greater number of ethnically diverse candidates to apply for job vacancies, and we offer dedicated support to new employees through our graduate programme and support the 10,000 Black Interns Programme. We will continue to work to progress our diversity actions to build greater representation. Our Group gender pay gap remained constant at 8.51%. As we look to develop female representation at all levels, we continue to focus on creating an environment for women to thrive and develop their careers and we have seen female representation in the upper-quartile grow from 16.9% in 2018 tothe current level of 25.6%. During the year we have been recognised for our progression in gender equality by external bodies. Our placement in the FTSE 250 Women Leaders Review reflected our high participation of female Board members resulting inPennon ranking 3 rd for Women on Boards in the FTSE 250 and 21 st overall. We are committed to deliver on our ambitions to build diversity and inclusion across the Group and the water Industry. Our Group Values Our Group values were launched in 2023 and underpin our Reward Strategy as well as our culture and will be reflected in individual and team remuneration, recognising and rewarding colleagues who showcase the Group values helping us to deliver what matters most to our customers andcommunities in the regions we serve. More can be read on the launch onpage 25. Colleague engagement RISE, our people forum has now been in place for 2 years, providing a two- way dialogue for all colleagues across the Group. This is regularly attended by senior leadership including the Group Chief Executive Officer, South West Water Director of People and Culture, the Group Chief People Officer and other members of the senior leadership. RISE is an established group provoking healthy debate and discussion on areas that matter to employees including reward. Representation is strong, with a RISE member for every 30 employees. This group continues to be a key source of dialogue and employee views for shaping future reward developments. The Committee is kept informed of themes and feedback from RISE discussions. We hold regular meetings with the recognised trades union representatives, keeping them informed of business developments and the People Strategy and recognising their role for colleague feedback and the insights they can provide on behalf of their members on a wide range of topics. Across the Group we consult on the pay of all colleagues. This will either be through the collective bargaining agreement in place with recognised trades unions or through our RISE panel for those outside of these arrangements. HomeSafe Making sure our colleagues and contractors get HomeSafe every day is fundamentally more important than remuneration. However, how we measure our performance, reward colleagues living by our values and the culture we create, has a direct influence on the health and safety of each other and we will continue to support this important initiative through our wider workforce remuneration principals and Executive Remuneration policy. Be the 156 Annual Report and Accounts 2024 « Pennon Group plc How our remuneration approach meets Section 40 of the UK Corporate Governance Code Clarity – remuneration arrangements should be transparent and promote effective engagement with shareholders and the workforce. The Committee seeks to promote transparent disclosure of remuneration arrangements, with full details of executive remuneration provided within theRemuneration Report each year. Incentive outcomes and the performance levels achieved against pre-set targets are clear. Consistent frameworks for annual incentives are used throughout all levels of the organisation, providing clarity of performance levels expected. The Committee welcomes dialogue on remuneration arrangements, with shareholders, our WaterShare+ Advisory panel and our colleagues either through our RISE panel or other employee forums. Simplicity – remuneration structures should avoid complexity and their rationale and operation should be easy to understand. The remuneration arrangements in place are simple, comprising base pay, pension, benefits, short-term and long-term incentive awards and infundamental construct remain consistent over time. Performance ranges where applicable are straightforward in nature. Maximum remuneration levels are set within the policy. Risk – remuneration arrangements should ensure reputational and other risks from excessive rewards, and behavioural risks that can arise from target-based incentive plans, are identified and mitigated. Remuneration arrangements are carefully considered by the Committee, toensure they reflect our values and those of a responsible business. Long-term sustainable performance is central to our delivery for all stakeholders and this is reflected in our long-term incentive plan, balancing both financial resilience and customer and environmental standards. Allincentive payments are scrutinised by the Committee and levels of reward positioned so that excess is avoided. The provisions for malus and clawback are in place across all leadership schemes. Predictability – the range of possible values of rewards to individual directors and any other limits or discretions should be identified and explained at the time of approving the policy. The Remuneration Policy sets the maximum levels for variable remuneration and for retirement benefits and other benefits, these are aligned to the wider organisation. All incentive payments are carefully scrutinised by the Committee using a discretion framework to assess audited results and making adjustment as appropriate when considering wider performance outcomes. Proportionality – the link between individual awards, the delivery of strategy and the long-term performance of the company should be clear. Outcomes should not reward poor performance. Careful consideration is given to the stretching targets that are selected, taking into account the long-term strategy of the Group and the expectations of all our stakeholders. Alignment to culture – incentive schemes should drive behaviours consistent with company purpose, values and strategy. Delivery for customers, communities, the environment and all stakeholders is at the forefront of our incentive arrangements. The Committee receives regular information on remuneration outcomes and arrangements for the wider workforce, employee engagement and interacts with colleagues acrossthe business. Statement of consideration of employment conditions elsewhere in the Company In setting executive remuneration the Committee takes account of employment market conditions and the pay and benefits differentials across the Group. The Committee considers annual summary reports of employee remuneration and the terms and conditions of employment within each operating company and has regard to these when considering remuneration for the Executive Directors and senior management. As part of this assessment the Committee considers various metrics including data on the ratio between CEO and all-employee pay, gender pay statistics and measures of employee engagement. The Board engaged on remuneration matters with the wider workforce, through many mechanisms including the employee RISE and the Partnership forum, the Big Chat and Open Door communications, on which more can be read on pages 25 to 27. Statement of consideration of shareholder views In developing this Remuneration Policy, the Committee took into account general good governance, best practice and evolving shareholder views. We regularly engage with major shareholders to understand their views on executive pay and their feedback informs our decision-making and the approach set out in this Policy. As detailed on page 152 to the extent that a further review of the Policy is initiated later in the year the Committee would engage with our major stakeholders as appropriate. 157Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Remuneration Committee report continued Single total figure of remuneration table (audited) Current Executive Directors Former Executive Director Susan Davy (£000) Steve Buck 1 (£000) Paul Boote 2 (£000) 2023/24 2022/23 2023/24 2023/24 2022/23 Base salary 492 475 164 240 309 Benefits 3 21 21 6 7 16 Pension 4 49 48 16 24 31 Total fixed pay 562 543 186 271 356 Annual Bonus (cash) (forgone) Nil Nil Nil Nil 51 Annual Bonus (deferred shares) (forgone) Nil Nil Nil Nil 51 LTIP - deferred reinvestment of shares 5,6 298 Nil Nil 172 138 Total fixed, variable and deferred remuneration 860 543 186 443 596 Total variable pay (actual) 298 Nil Nil 172 240 Total variable pay (cash) Nil Nil Nil Nil 51 Total variable pay (forgone) 7,8 237 367 75 115 – 1.

Remuneration for Paul Boote relates to the period 1 st April 2023 until he stepped down from his role and left the Group on 31 st December 2023. 3. Benefits comprise a car allowance, fuel allowance, medical insurance, and income protection. 4. See page 162 for further information on retirement benefits. 5. For 2023/24, the 2021 LTIP has been valued based on the average share price during the three-month period to 31 st March 2024 of 697p, together with an estimate of the accrued dividends payable on the vesting shares. Of the vested amount, none of the award is attributable to share price appreciation over the performance period. The Committee did not exercise any discretion in relation to share price changes. Vested awards are subject to a two-year holding period. 6. For 2022/23, the 2020 LTIP value for Paul Boote has been restated to reflect the share price at the date of vesting of 661p. The value includes accrued dividends over the vesting period. The Committee did not exercise any discretion in relation to share price changes. These LTIP awards are subject to a two-year holding period. 7. For 2022/23, the CEO recommended that her bonus and 2020 LTIP award were forgone in full. An equivalent value was diverted into a future issuance under the Company’s WaterShare+ scheme. The value of the forgone LTIP award reflects the share price at the date of vesting of 661p. 8. For 2023/24, in recognition of the current external environment, the Committee determined that no bonus would be paid to Executive Directors in respect of the year. This was consistent with management’s recommendation for a zero bonus outturn. Notes to the single figure table Fixed pay Details of fixed pay for Steve Buck can be found on page 162. Retirement benefits for both Executive Directors have been set at 10% of salary since appointment, which is aligned to the rate available to the majority of the wider workforce. Further detail on pension arrangements is set out on page 162. Variable pay Following guidance provided by Ofwat, we have taken steps to ensure that performance-related pay outcomes for the Executive Directors are funded at the Group level and will not therefore be funded by customers. 158 Annual Report and Accounts 2024 « Pennon Group plc Annual bonus outturn for 2023/24 Consistent with prior years, the bonus is based on a rounded assessment of performance. In line with regulatory guidance, 60% of the bonus is linked to delivery of stretching objectives for our customers, communities and the environment. The bonus includes a profit measure which ensures that the Company maintains a focus on financial resilience, enabling us to invest in the future and deliver robust and sustainable performance for all of our stakeholders. The Group Executive Directors are currently remunerated for delivery of the Group strategy, including Pennon Water Services, Water2Business, Pennon Power and the respective licensed water businesses, which will now include SES Water, in one plan. Variable incentives are not recharged to the individual water companies, but are instead funded at a Group level. During the year and over recent months, Ofwat has provided substantial feedback regarding the operation of bonus schemes across the sector. In particular Ofwat stressed the need for inclusion of metrics directly related to environmental performance and water quality in the annual bonus. Whilst these measures were included in the 2024 LTIP award, they were not in the original bonus targets set for 2023/24. In direct response to Ofwat feedback, the scorecard linked to customers, communities and the environment for 2023/24 was adapted by the Committee to include additional metrics which were considered to be of particular importance to Ofwat and our customers. Although the inclusion of these additional metrics required a review of the weighting for individual measures, the overall weighting on metrics relating to customers, communities and the environment remains unchanged at 60%. The revised scorecard explicitly captures performance under a wide range of factors, reflecting the multiple areas which are important to our stakeholders. Itisvital that the business continues to perform across these areas of focus. Further detail of the underlying targets is set out on page 160. The overall formulaic outcome was 46.5% of maximum. Consistent with prior years the Committee also undertook a holistic assessment of performance in order to determine whether the formulaic outturn remains appropriate in the context of broader performance. This review considers performance from a number of different perspectives. For 2023/24 performance theCommittee also considered the outcome against best practice principles recently developed in collaboration with sector peers. The framework used in this assessment is summarised below. Holistic performance assessment Culture and conduct Focus on significant health and safety, culture and operational events Alignment with customers, communities and the environment Including customer experience, water quality and resilience, pollution incidents/ EPA and emissions reduction Consideration of external environment Including the shareholder, employee and wider stakeholder experience Input from other Board Committees Including ESG and Health and Safety Committees, HR, Compliance, Internal Audit andWaterShare plus panel Broader financial, operating and strategic performance Including impact of exceptional and one-off events Sector best practice principles Assessment versus best practice principles developed bysector Formulaic outcome Determination of final outcome The Committee carefully considered the formulaic outcome of the annual bonus of 46.5% of maximum and debated this at length. After applying the Committee's discretion framework in respect of South West Water's environmental and pollution performance, it was decided to reduce the formulaic outturn to 38.5%. Furthermore, in recognition of the current external environment, the Committee determined that no bonus would be paid to Executive Directors in respect of the year. This was consistent with managements recommendation for a zero bonus outturn. As noted in the 2023 Annual Report and Accounts, the Chief Executive Officer waived her entitlement to the bonus for FY 2022/23 and funds of an equivalent value were diverted into the next WaterShare+ issuance. 159Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Remuneration Committee report continued Measure Weighting Targets Achievement Outcome Financial resilience Underlying PBT 40% • Threshold – £38.02m • Maximum – £40.74m • Outcome (£16.8m / £19.3m excluding SES) impacted by inflation impact on debt instruments 0% Environmental Licensed water business environmental performance South West Water – Environment and Pollution 18.5% • EPA – towards 4 • Cat 1-2 Pollutions – Amber and above • Cat 1-3 Pollutions – 64 • Numerical compliance – maintain high performance • GHG emissions - 68% reduction • EPA rating (2) and Cat 1-3 below hurdle – nilpayout • Numerical compliance and Cat 1-2 Pollutions (Amber) within range • Renewables generation within range 8% South West Water - Water quality and resilience 16.5% • PCC (3 year) – 138.7 • Leakage (3 year) – 109.3 • Sewer Collapses – 14.76 • Mains Repairs – 136.6 • Water resource and resilience – water resource storage to achieve 90% • Bathing water quality – 98%-100% • Enabling biodiversity - progress of K7 target 13,000 • PCC within range • Leakage, sewer collapses and mains repairs above target • Water resource plan ahead of schedule • Bathing water quality of 100% • Enabling biodiversity and GHG emissions above target 16.5% Bristol Water - Water quality and resilience 3% • Leakage (3 year) – 109.3 • Main repairs – 132.7 • PCC – 141.3 • Leakage below hurdle – nil payout • Main repairs above target • PCC within range 2% SES - Water quality and resilience 1% • Leakage – 21.6 • PCC – 142.6 • Leakage above target • PCC within range 1% Pennon Power 5% • Delivery against milestone events • 4 sites acquired • Dunfermline construction contract signed • Preferred partner appointed for other 3 5% Customer service Licensed water business service performance South West Water – Customer service 4% • Unplanned outage – 2.34 • Supply – 5m 0s • CRI – 2 • PSR: Reach 5% Attempted Contacts 90% Actual Contacts 35% • Internal Flooding – 1.44 • External flooding – 1,260 • Unplanned outage, PSR and internal flooding above target • Supply, CRI and external flooding below target – nil payout 2.5% Bristol Water – Customer service 2% • Unplanned outage – 2.34 • Supply – 5m 0s • CRI – 2 • PSR: Reach 5% Attempted Contacts 90% Actual Contacts 35% • Unplanned outage within range • Supply and CRI below hurdle – nil payout • PSR above target 1.5% SES – Customer service 1% • Supply – 5m 0s • CRI – 2 • PSR • Supply, CRI and PSR above target 1% B2B Retail PWS Customer Retention 5% • Delivery against customer measures and Net Growth • Retention of tendered contracts 100% • +1% Market Share (excl. de-reg) • Revenue retention c.97%, EBITDA +72% on 2023 5% Responsible Business Social and governance 4% • Sustainalytics – 80% • Fair Tax – maintain • Sustainable Financing – 75% • Health & Safety – 20 LTIs • Sustainalytics – 82.5% • Fair Tax – maintain • Sustainable Debt – 82% • Health & Safety – 15 LTIs 4% 160 Annual Report and Accounts 2024 « Pennon Group plc Long-term incentive outturn for 2023/24 The awards in the single figure table relate to the LTIP awards granted on 1 st July 2021 which are due to vest on 1 st July 2024. These share awards were subject to performance targets relating to RORE, sustainable dividends and a basket of customer measures assessing average relative performance to water companies over the three year period and PWS Trustpilot score. The 2021 awards were the first to include metrics related to customer performance in line with the sector best practice. Awards granted in 2023 were further adapted to also included water quality metrics in order to further align with Ofwat guidance. The table below provides an overview of performance against the targets set: Measures Threshold (25% of maximum) Maximum (100% of maximum) Achievement Vesting Outcome (% of maximum) RORE (33% of award) 6% 8% 7.6% 85% Sustainable dividend measure (33%of award) 2.6x 3.6x 3.04 58% Basket of Customer Measures 3 (33% of award) C-MeX SWW (45%) 11th 1st 13 0% C-MeX BRL(15%) 9th 1st 4 88.8% R-MeX SWW (7.5%) 9th 1st 9 25% R-MeX BRL (2.5%) 9th 1st 3 92.5% D-MeX SWW (7.5%) 9th 1st 7 55% D-MeX BRL (2.5%) 9th 1st 9 25% MPS SWW (7.5%) 9th 1st 5 85% MPS BRL(2.5%) 9th 1st 4 88.8% Trustpilot Score (10%) 4.5 5 4.8 70% Overall vesting outcome 60.2% 1. For below-threshold performance for any of the performance conditions, 0% vests in respect of that performance condition. 2. Straight-line vesting between points. 3. For the relative measures, 25% vesting for threshold performance, 85% vesting for upper-quartile performance and maximum vesting for market leading performance. Straight-line vesting between these points. For these relative metrics, 75% is based on South West Water performance with the balance based on Bristol Water. Assessment of overall performance Vesting of the award is subject to an ‘underpin’ relating to overall Group performance. Consistent with the approach described for the annual bonus, the Committee utilises a holistic performance assessment framework to support this review which considers performance from a number of different perspectives. For the 2021 award, the following factors were noted: • The progress made against customer related metrics is fairly reflected in the scorecard. • The Group remains in a robust financial position, and is well-positioned for the next regulatory period with an efficiently funded balance sheet. Ongoing efficiency programmes are keeping cost increases below inflation, despite impacts of the unprecedented wet weather. Our profitable B2B retailers have seen a c.52% increase in EBITDA. Water group gearing is at 63.5% reflecting increased capital expenditure spend and timing of RCV build. Liquidity of £1.2 billion has been raised since March 2023. There was also record support for our customers of £100 million (K7 to date). • We are making progress delivering on our four priorities. We have broken the drought cycle for Devon and Cornwall with 100% strategic reservoir capacity achieved in April – ahead of target and we have maintained 100% bathing water quality for the third year in a row. We also remain on track to deliver our ambitious Net Zero programme by 2030. • While performance in certain areas was impacted by climate factors – 2023 was the fifth wettest on record with rainfall in the second half of the year 50% above the long-term average – it was recognised that there remains scope for improvement. The Group has re-profiled delivery of EPA 4-star until 2025, maintaining the gains delivered in 2022. The Group had no Category 1 incidents in the year and both Category 2 incidents were investigated and determined to be one-off in nature and not due to systemic issues. That said, this remains a top priority for the Board. Outstanding investigations and response in relation to leakages and wastewater treatment were also considered when reviewing outcomes. As noted above, the bonus outcome has been reduced to nil. • The acquisition of SES Water represents a significant milestone and is consistent with our strategy. There was significant investor support for both the acquisition and the £180m equity capital raise. • The Committee considered matters of broader culture and conduct and noted a number of factors including the roll out of Group-wide values and the continued positive safety culture as demonstrated by the 46% reduction in lost time injuries. Overall the Committee was satisfied that the vesting outcome of 60.2% of maximum represented a fair reflection of overall Group performance over the last three years. Vested awards for the CEO and former CFO will not be released in 2024. Instead awards will remain subject a two-year holding period and therefore participants remain invested in the longer-term performance of the business. Awards are also subject to malus and clawback provisions. Consistent with guidance provided by Ofwat, these awards to executive directors are funded at the Group level, rather than being recharged to the individual water companies, and will therefore not be funded by customers. As noted in the 2023 Annual Report, the CEO waived her right to the vesting of the 2020 LTIP award in 2023. 161Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Remuneration Committee report continued Retirement benefits and entitlements (audited information) Details of the Directors’ pension entitlements and pension-related benefits during the year are as follows.

For2023/24 this comprised an employer’s contribution of £10,000 and a cash sum of £39,000. She is a member of Pennon Group’s defined contribution pension arrangements and is entitled to access the retirement fund in the Master Trust from age 55. Steve Buck received an overall pension benefit from the Company equivalent to 10% of his salary for the period 27 th November 2023 to 31 st March 2024.

He is a member of Pennon Group’s defined contribution pension arrangements and is entitled to access the retirement fund in the Master Trust from age 55. Paul Boote received a pension contribution of 10% of his salary for the year which included a period of contractual notice. This was paid as a cash allowance of£23,986 and he is entitled to access the retirement fund in the Master Trust from age 55. The employer’s contribution to the pension for Executive Directors is deducted from their overall retirement benefit. No additional benefits will become receivable by a Director if the Director retires early. Arrangements for the Incoming Group Chief Financial Officer Steve Buck was appointed to the Board on 27 th November 2023 and he was appointed to the role of Group Chief Financial Officer effective 1 January 2024. Steve has been appointed on a salary of £470,000, modestly positioned 3.6% higher than his previous salary within the water sector. Whilst we recognise that this represents a material increase relative to the previous incumbent, his uplift in salary is substantially lower than typical premia paid to executives when changing roles. Steve’s salary in his previous role was positioned between the median and upper quartile of FTSE 250 reference points. The Committee considered sector practice and market pay levels observed during the recruitment process, as well as Steve’s significant experience and knowledge of the sector, and is of the view that his salary is appropriately positioned. Steve’s incentive opportunity levels are aligned to the policy and consistent with the level awarded to the previous incumbent. While eligible for a pro-rated 2023/24 bonus in respect of the portion of the year employed, as noted above no bonus was paid. Steve has also been granted a 2023 LTIP award at the normal award level of 150% of salary. Steve is also being compensated in respect of variable remuneration forfeited as a result of leaving his previous employer. These buy-out awards are on a broadly like-for-like basis. This includes eligibility for a cash payment in respect of the short-term (i.e. annual bonus) element of his variable pay, ordinarily payable in 2024/25. The value of this award will be based on the actual performance as disclosed in the Anglian Water annual report. The value of this award willbe disclosed in next year’s annual report once determined. Steve will also be compensated in respect of his deferred bonus awards. Awards will vest and be released in line with the original timescales. The value of the awards on grant are set out below. The original awards are also entitled to a CPIH based adjustment over the relevant vesting periods. The actual value of awards will be included in the single figure table in the financial year of vesting. • 2021 award – £183k – delivered in July 2024 • 2022 award – £228k – delivered in July 2024 and 50% in July 2025 • 2023 award – £259k – delivered in July 2025 and 50% in July 2026 Awards are also subject to malus and clawback provisions. Consistent with the Remuneration Policy Steve will receive retirement benefits of 10% of salary consistent with benefit levels available to wider workforce. Hewill also be provided with role-appropriate benefits including car and fuel allowance, medical insurance, and income protection. Steve was also eligible foraone-off allowance in line with our Policy to facilitate relocation, up to a maximum of £75k per annum for two years. 162 Annual Report and Accounts 2024 « Pennon Group plc Arrangements for the Outgoing Group Chief Financial Officer Paul Boote stepped down from the Board and left the Group on 31 st December 2023.

Health and car benefit will continue until the end of his 12-month notice period. Paul also received a payment of £11,636 in respect of accrued but untaken holiday. Paul was eligible for an annual bonus in respect of 2023/24, pro-rated based on the portion of the financial year employed. As detailed earlier in the report, zero bonus will be paid. Outstanding LTIP awards will be subject to time pro-rating based on the proportion of the performance period employed, with performance outcomes assessed at the end of the relevant performance period.

Had the CEO received the annual bonus shown in the single figure table, as amount forgone, theratio would have been 28:1. The ratio is higher than in 2022/23 when the CEO opted to forgo her variable pay for that year. It is lower than the ratio in preceding years. The changes are partially due to our strategy of developing pay for front line roles, which has led to an increase in median pay. Year Method 25 th percentile (P25) pay ratio Median (P50) pay ratio 75 th percentile (P75) pay ratio 2023/24 actual outcomes A 29:1 22:1 17:1 2023/24 outcome with bonus amount forgone A 37:1 28:1 22:1 2022/23 1 actual outcomes A 20:1 16:1 12:1 2022/23 2 formulaic outcomes A 34:1 26:1 20:1 2021/22 A 59:1 44:1 36:1 2020/21 3 A 95:1 69:1 55:1 2019/20 A 87:1 68:1 50:1 1. For 2022/23, the CEO recommended that her bonus and 2020 LTIP award were forgone. An amount of the equivalent value was to be diverted into a future issuance under the Company’s WaterShare+ scheme. The CEO pay ratio for this year therefore does not include any variable incentive pay. 2. This shows the values for 2022/23 had the CEO accepted her variable incentive pay awards in 2023. 3. The CEO ratio for 2021/22 is lower than previous years, partially due to the lower salary and pension benefit received by Susan Davy, compared to her predecessor. The total single figure used in the ratio in 2020/21 was a combined total single figure pro-rated to reflect the change in CEO mid-year. Option A has been used for the calculations as it is the most statistically accurate approach. The employees at the lower quartile, median and upper quartile (P25, P50 and P75 respectively) have been determined based on a calculation of total remuneration for the financial year 1 st April 2023 to 31 st March 2024. Base salary for part-time employees and new joiners within the applicable period has been converted to full-time equivalents for the purpose of the calculations. The total singe figure for the CEO for 2022/23 was not subject to restating as variable pay was foregone. The restated value for the ratio illustrating the formulaic outturn for 2022/23 has led to a reduction in the CEO ratio for the median employee from 28:1 to 26:1. The validated P11D data for 2022/23 did not lead to any adjustments to the ratio. Monthly pay-rolling of P11d information was introduced for the 2023 financial year and now reflects actual values in year. For 2023/24 the total remuneration for the employees identified at P25, P50 and P75 is £29,617, £39,071 and £50,343 respectively. The base salary of 2023/24 for the employees identified at P25, P50 and P75 is £27,500, £28,117 and £44,853 respectively. Further detail on our approach to pay in the wider organisation isset out on page 153. As the Committee spends a considerable amount of time on matters relating to remuneration arrangements for the wider workforce, weare comfortable that the median pay ratio is consistent with our wider policies on pay, reward and progression and reward for the Group as a whole.

Remuneration Committee report continued 166 Annual Report and Accounts 2024 « Pennon Group plc Directors’ shareholding and interest in shares The Remuneration Committee believes that the interests of Executive Directors and senior management should be closely aligned with the interests ofshareholders.

Such authorisation can be reviewed at any time but is always subject to annual review.

Disclosures Listing Rule 9.8.4 disclosures: There is no information to be disclosed under Listing Rule (9.8.4R.) The Company has no long-term incentive arrangements in place under LR 9.4.2R where the only participant is a Director and the arrangement is established specifically to facilitate, in unusual circumstances, the recruitment or retention of the individual. Financial Risk Management: The Directors have carried out a robust assessment of the principal and emerging risks facing the Group, including In relation to its business model, future performance, solvency and liquidity. Details of our principal risks and association mitigations are set out on pages 55 to 64. Note 3 to the Financial Statements gives details of the Group’s financial risk management policies and related exposures. This note is incorporated by reference and deemed to form part of this Report. Going Concern: The going concern basis has been adopted in preparing these financial statements. At 31 st March 2024 the Group has access to undrawn committed funds and cash and cash deposits totalling £601.4 million, including cash and other short-term deposits of £171.4 million and £430.0 million of undrawn facilities. Cash and other short-term deposits include £26.0 million of restricted funds deposited with lessors which are available for access, subject to being replaced by an equivalent valued security. Considering this the Group has a headroom of �435 million, including the impact of £98 million of loans and facilities due for maturity or renewal within the going concern period through to 31 st May 2025. In making their assessment, the Directors reviewed the principal risks and considered which risks might threaten the Group’s going concern status, to do this the Group’s business plan has been stress-tested. Whilst the Group’s risk management processes seek to mitigate the impact of principal risks as set out on pages 55 to 64, individual sensitivities against these risks have been identified. These sensitivities, which are ascribed a value with reference to risk weighting, factoring in the likelihood of occurrence and financial impact, were applied to the baseline financial forecast which uses the Group’s annual budget for FY 2024/25, including the impact of the acquisition of Sutton and East Surrey Holdings Limited, and longer-term strategic business plan for the remainder of the going concern period to 31 st May 2025. The risks and sensitivities include consideration of: legislative impacts such as change in government policy and non-compliance with laws and regulations, macro-economic impacts such as inflation and interest rate increases, regulatory impacts such as the ongoing Ofwat price and tariff review, i.e. PR24, covering the period from April 2025 to March 2030, and operational impacts such as ensuring adequate water resources and failure of operational assets. A combined stress testing scenario has been performed to assess the overall impact of these individual scenarios impacting the Group collectively. The combined weighted impact of the risks occurring is c.£80 million, this value is considered equivalent to an extreme one-off event that could occur within a year, the probability of such an event happening is deemed unlikely. Through this testing, it has been determined that none of the individual principal risks would in isolation, or in aggregate, compromise the going concern of the Group over the going concern period, the assessment has been considered by reviewing the impact on the solvency position as well as debt and interest covenants. In the combined scenario to ensure that the Group was able to continue as a going concern, additional mitigations could be deployed to reduce gearing and increase covenant headroom. In the combined stress test scenario, the group has sufficient liquidity and covenant headroom which reflects that no mitigations would be needed by the Group. However if required additional mitigations could be deployed to reduce gearing and increase covenant headroom. Examples of mitigations could include: reduction in discretionary operational expenditure, deferral of capital expenditure and/or cancellation of non- essential capital expenditure, reduction in the amount of dividend payable, and raising additional funding. 172 Annual Report and Accounts 2024 « Pennon Group plc In addition, we have modelled a reverse engineered scenario that could possibly compromise the Group’s solvency over the going concern assessment period. This scenario builds on the factors above and additionally assumes all the Group’s principal risks are incurred within the going concern period, with no probability weightings attached. The Board considered the likelihood of this scenario on the Group’s solvency over the going concern period as remote, given this would require all of the principal risks to be incurred at maximum impact within the same time frame, without implementing controllable mitigations, as noted above, or raising additionalfunding. We have considered the Group’s funding position and financial projections, which take into account a range of possible impacts, including the refinancing required within and immediately after the going concern assessment period. Subsequent to the year end date, the Group has secured a £150 million private placement and a £350 million liquidity facility, which reflects on the Group’s ability to secure finance. Having considered these factors, the Directors have a reasonable expectation that the Group will meet the requirements of its covenants and has adequate resources tocontinue in operational existence for the period to at least the end of the going concern assessment period of 31 st May 2025, and that there are no material uncertainties to disclose. For this reason, they continue to adopt thegoing concern basis in preparing the financial statements. Data: As part of our business activity, the Group processes large amounts of personal data. The Group recognises that to enable this use of personal data it is critical that we continue to build on our approach to applying privacy in a lawful and ethical way.

Statement of Directors’ responsibilities The Directors are responsible for preparing the Annual Report and the Group financial statements in accordance with applicable law and regulations. Company law requires the Directors to prepare financial statements for each financial year. Under that law the Directors have elected to prepare the Group and parent company financial statements in accordance with UK adopted international accounting standards (IFRSs) in conformity with the Companies Act 2006. Under company law the Directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the Group and the Company and of the profit or loss of the Group for the year. In preparing these financial statements the Directors are required to: • select suitable accounting policies in accordance with IAS 8 Accounting Policies, Changes in Estimates and Errors and then apply them consistently; • make judgments and accounting estimates that are reasonable andprudent; • present information, including accounting policies, in a manner that provides relevant, reliable, comparable and understandable information; • provide additional disclosures when compliance with the specific requirements of IFRSs is insufficient to enable users to understand the impact of particular transactions, other events and conditions of the Group’s financial position and financial performance; • in respect of the Group financial statements, state whether UK adopted international accounting standards in conformity with the Companies Act2006 have been followed, subject to any material departures disclosed and explained in the financial statements; • in respect of the parent company financial statements, state whether UK adopted international accounting standards in conformity with the Companies Act 2006 have been followed; and • prepare the financial statements on the going concern basis unless it is appropriate to presume that the Company and/or Group will not continue in business. The Directors are responsible for keeping adequate accounting records that are sufficient to show and explain the Company’s and Group’s transactions and disclose with reasonable accuracy at any time the financial position of the Group and the Company; and enable them to ensure that the Company and Group financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the Group and the Company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities. Under applicable law and regulations, the Directors are also responsible for preparing a Strategic Report, Directors’ Report, Directors’ Remuneration Report and Corporate Governance Statement that comply with the law and those regulations. TheDirectors are responsible for the maintenance and integrity of the corporate and financial information included on the Company’s website. Each of the Directors, whose names and functions are listed on pages 116 to 117, confirms that, to the best of her or his knowledge: The consolidated financial statements, prepared in accordance with UK adopted international accounting standards in conformity with the Companies Act 2006 give a true and fair view of the assets, liabilities, financial position and profit of the parent company and undertakings included in the consolidation taken as a whole. The Annual Report, including the Strategic Report (pages 1 to 111), includes a fair review of the development and performance of the business during the year and the position of the Company and undertakings included in the consolidation taken as a whole, together with a description of the principal risks and uncertainties they face. They consider that the Annual Report, taken as a whole, is fair, balanced and understandable, and provides the information necessary for shareholders to assess the Company’s position, performance, business model and strategy. Statement as to disclosure of information to the auditor i. So far as each of the Directors in office at the date of the signing of the report is aware, there is no relevant audit information of which the Company’s auditor is unaware; and ii. Each of the Directors has taken all the steps each Director ought to have taken individually as a Director in order to make herself or himself aware of any relevant audit information and to establish that the Company’s auditor is aware of that information. The Directors’ Report consisting of pages 112 to 174 was approved by the Board on 20 th May 2024. By order of the Board Andrew Garard Group General Counsel and Company Secretary 20 th May 2024 Directors’ Report continued 174 Annual Report and Accounts 2024 « Pennon Group plc Independent Auditor’s report to the members of Pennon Group plc Conclusions relating to going concern In auditing the financial statements, we have concluded that the directors’ use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Our evaluation of the directors’ assessment of the group and parent company’s ability to continue to adopt the going concern basis of accounting included the following procedures: • We obtained an understanding of the process undertaken by management to perform the going concern assessment. • We have obtained management’s going concern assessment, including the cash flow forecast, liquidity requirements and forecast covenant calculations for the going concern period which covers the period from approval of the 2024 financial statements through to 31 May 2025, and have tested this for arithmetical accuracy. Management has modelled a downside scenario in their cash flow forecast and covenant calculations in order to incorporate unexpected changes in the forecast liquidity and covenant compliance of the group. • We have challenged the forecasts used for the going concern assessment period, agreed the data to the Board approved plan and, where applicable, corroborated the data with audit information from other areas, including capital commitments, impairment and deferred tax asset recoverability testing. We have evaluated the appropriateness of the key assumptions in management’s forecasts including revenue growth, by comparing these to year-to-date performance and through consideration of historical forecasting accuracy and the impact of regulatory price increases. • The largest component of the group’s operations is the regulated water business, undertaken by South West Water Limited, which is subject to five-year price control periods which set the basis of allowed tariff changes. The current period runs to March 2025 and the tariffs allowable for the next five year period to 31 March 2030 are currently under review by Ofwat. We have compared the key assumptions in the group’s regulated water business forecasts to the business plans and pricing determinations submitted to Ofwat, for consistency. In addition to this we confirmed that, within the downside scenario, management has considered the risk of changes to the proposed tariffs and the impact this could have on forecast liquidity and covenant compliance of the group. • We have evaluated management’s stress test modelling including management’s downside scenario and specific risk register probability- weighted scenarios, to understand the impact on the group’s liquidity andcovenant ratios. Management has also modelled a reverse engineered scenario (reverse stress test) assuming all the principal risks materialise within the going concern period with no probability weightings attached. We assessed the reasonableness of management’s stress test scenarios byperforming our own sensitivity analysis for severe but plausible scenarios. • We have compared the risks identified and modelled in the cash flow forecasts of management’s downside scenario to the group risk register and evaluated the quantification by management. We have considered whether there are other alternative risks that should be taken into consideration based on our knowledge of the business. Our procedures included evaluating management’s assessment of the impact of climate change within the going concern period, including the principal risk of availability of sufficient water resources to meet current and future demand, as well assufficiency of funds available to the Group to support the required capitalexpenditure. • We have compared facilities assumed in the forecasts to supporting loan documentation and to covenant terms. For facilities, where changes to terms are not finalised or facilities are unagreed at the date of approval of the financial statements, we have evaluated the impact on covenants and liquidity headroom based on existing terms. • We have evaluated, including assistance from our specialist, events impacting the group immediately after the end of the going concern assessment period, including the effects of maturity of loans and facilities on the group’s ability to continue as a going concern. • We performed testing to consider the likelihood of a scenario causing a liquidity issue or breach of covenants, including the impact of controllable mitigating actions, where relevant. Opinion In our opinion: • Pennon Group plc’s group financial statements and parent company financial statements (the “financial statements”) give a true and fair view of the state of the group’s and of the parent company’s affairs asat31 March 2024 and of the group’s loss for the year then ended; • the group financial statements have been properly prepared in accordance with UK adopted international accounting standards; • the parent company financial statements have been properly prepared in accordance with UK adopted international accounting standards as applied in accordance with section 408 of the Companies Act 2006; and • the financial statements have been prepared in accordance with the requirements of the Companies Act 2006. We have audited the financial statements of Pennon Group plc (the ‘parent company’) and its subsidiaries (the ‘group’) for the year ended 31 March 2024 which comprise: Group Parent company Consolidated balance sheet as at 31 March 2024 Balance sheet as at 31 March 2024 Consolidated income statement for the year then ended Statement of changes in equity for the year then ended Consolidated statement of comprehensive income for the year then ended Statement of cash flows for the year then ended Consolidated statement of changes in equity for the year then ended Related notes 1 to 44 to the financial statements, including material accounting policy information Consolidated statement of cash flows for the year then ended Related notes 1 to 44 to the financial statements, including material accounting policy information The financial reporting framework that has been applied in their preparation is applicable law and UK adopted international accounting standards and as regards the parent company financial statements, as applied in accordance with section 408 of the Companies Act 2006. Basis for opinion We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the financial statements section of our report. We believe that the audit evidence we have obtained is sufficient and appropriate to provide abasis for our opinion. Independence We are independent of the group and parent in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard as applied to listed public interest entities, and we have fulfilled our other ethical responsibilities in accordance with these requirements. The non-audit services prohibited by the FRC’s Ethical Standard were not provided to the group or the parent company and we remain independent ofthe group and the parent company in conducting the audit. 175Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Independent Auditor’s report to the members of Pennon Group plc continued • We have reviewed the group’s going concern disclosures included in the annual report in order to assess whether the disclosures were appropriate and in conformity with the reporting standards. We observed at 31 March 2024, the group had access to undrawn committed facilities of £430.0 million and cash and short-term and other deposits totalling £171.4 million (£134.1 million excluding restricted funds). The group generated positive net cash flows from operating activities of £148.9 million. Subsequent to the year end date, the group has secured a £150 million private placement and a £350 million liquidity facility. Management’s forecasts indicate there is headroom in the base case and in the downside scenario. Management considers the reverse engineered scenario, that all the group’s principal risks are incurred within the going concern period with no probability weightings attached, to be remote. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the group and parent company’s ability to continue as a going concern for a period to 31 May 2025. In relation to the group and parent company’s reporting on how they have applied the UK Corporate Governance Code, we have nothing material to add or draw attention to in relation to the directors’ statement in the financial statements about whether the directors considered it appropriate to adopt the going concern basis of accounting. Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report. However, because not all future events or conditions can be predicted, this statement is not a guarantee as to the group’s ability to continue as a going concern. Overview of our audit approach Audit scope We performed an audit of the complete financial information of three components and specified audit procedures on a further three components. The components where we performed full audit procedures accounted for 100% of Earnings before interest, taxes and non-underlying items, 96% of Revenue and 90% of Total assets. Key audit matters Revenue recognition across the group’s operations in relation to accrued income relating to measuredsupplies Valuation of the expected credit loss provision forcustomer balances across the group Capitalisation of costs relating to the capital programme Materiality Overall Group materiality of £8.3m which represents 5%of the Group’s earnings before interest, taxes andnon- underlying items. An overview of the scope of the parent company andgroup audits Tailoring the scope Our assessment of audit risk, our evaluation of materiality and our allocation of performance materiality determine our audit scope for each company within the Group. Taken together, this enables us to form an opinion on the consolidated financial statements. We take into account size, risk profile, the organisation of the group and effectiveness of group-wide controls, changes in the business environment, the potential impact of climate change and other factors such as recent Internal audit results when assessing the level ofwork to be performed at each company. In assessing the risk of material misstatement to the Group financial statements, and to ensure we had adequate quantitative coverage of significant accounts in the financial statements, of the seven reporting components of the Group, we selected six components covering the entities, Pennon Group plc, South West Water Limited, Pennon Water Services Limited, Bristol Water plc, Pennon Power Limited and Sutton and East Surrey Group Holdings Limited, which represent the principal business units within the Group. Of the six components selected, we performed an audit of the complete financial information of three components (“full scope components”) which were selected based on their size or risk characteristics. For the current year, the full scope components contributed 100% (2023: 100%) of the Group’s earnings before interest and taxes and non-underlying items, 96% (2023: 100%) of the Group’s Revenue and 90% (2023: 94%) of the Group’s Total assets. For the remaining three components (“specified procedures scope components”), we performed specified audit procedures on specific accounts within that component that we considered had the potential for the greatest impact on the significant accounts in the financial statements either because of the size of these accounts or their risk profile. The audit scope of these components may not have included testing of all significant accounts of the component but will have contributed to the coverage of significant accounts tested for the Group. The remaining component accounts for not more than 1% of the group’s earnings before interest, taxes and non-underlying items. For these components, we performed other procedures, including analytical review, testing of consolidation journals and intercompany eliminations to respond to any potential risks of material misstatement to the Group financial statements. Changes from the prior year Following the acquisition of Sutton and East Surrey Group Holdings Limited, we included this as a specified audit procedures scope component based on its size and risk characteristics and a non-EY firm performed the specified procedures under the instructions of the primary audit engagement team. Pennon Power Limited a dormant company in prior year acquired four companies with future renewable energy generation capacity in the current year. Following the acquisition activity within Pennon Power Limited we included this entity as specified audit procedures scope component based on its size and risk characteristics and these procedures were performed by EY primary audit team. 176 Annual Report and Accounts 2024 « Pennon Group plc Involvement with component teams In establishing our overall approach to the Group audit, we determined the type of work that needed to be undertaken at each of the components by us, as the primary audit engagement team, or by component auditors, including non-EY firms, operating under our instruction. The audit teams for Pennon Group plc, South West Water and Pennon Water Services are led by the Senior Statutory Auditor with a non-EY firm auditing the specified procedures scope component, Sutton and East Surrey Group Holdings Ltd. Where the work was performed by component auditors, we determined the appropriate level of involvement to enable us to determine that sufficient audit evidence had been obtained as a basis for our opinion on the Group asa whole. The primary team interacted regularly with the component teams where appropriate during various stages of the audit, reviewed relevant working papers and were responsible for the scope and direction of the audit process. This, together with the additional procedures performed at Group level, gave us appropriate evidence for our opinion on the Group financial statements. We maintained regular open dialogue with all component audit teams in addition to holding formal meetings to ensure that we were fully aware of their progress and results of their procedures. The Senior Statutory Auditor discussed the planned audit approach with the component teams and any issues arising from their work, attended meetings with management and reviewed key audit working papers on risk areas. This, together with the additional procedures performed at group level, gave us appropriate evidence for our opinion on the group financial statements. Climate change Stakeholders are increasingly interested in how climate change will impact Pennon Group plc. The group has determined that the most significant future impacts from climate change on their operations will be from physical and transitional climate-related risk. These are explained on pages 78-109 in the required Task Force On Climate Related Financial Disclosures and on pages 55 to 64 in the principal risks and uncertainties. They have also explained their climate commitments on pages 69 to 70. All of these disclosures form part of the “Other information,” rather than the audited financial statements. Our procedures on these unaudited disclosures therefore consisted solely of considering whether they are materially inconsistent with the financial statements or our knowledge obtained in the course of the audit or otherwiseappear to be materially misstated, in line with our responsibilities on “Other information”. In planning and performing our audit we assessed the potential impacts of climate change on the group’s business and any consequential material impact on its financial statements. The group has explained in their basis of preparation to the financial statements how they have reflected the impact of climate change in their financial statements including how this aligns with their commitment to the aspirations of the Paris Agreement to achieve net zero emissions by 2050 which forms part of their disclosures within the Task Force on Climate related Financial Disclosures which forms part of “Other information”. Significant judgements and estimates relating to climate change are included in note 2(a) Basis of preparation and note 4 Critical accounting judgements and estimates. These disclosures also explain where governmental and societal responses to climate change risks are still developing, and where the degree of certainty of these changes means that they cannot be taken into account when determining asset and liability valuations under the requirements of UK adopted international accounting standards. In Note 4 to the financial statements supplementary narrative explanation of the impact of climate change on long life assets and availability of sufficient funds for the required capital expenditure, has been provided, concluding that the Group continues to have sufficient funding in place and there is no specific impact on useful lives of long life assets as at 31 March 2024. Our audit effort in considering the impact of climate change on the financial statements was focused on evaluating management’s assessment of the impact of climate risk, physical and transition, their climate commitments, the effects of material climate risks disclosed on pages 78-109 and the significant judgements and estimates disclosed in note 4 and whether these have been appropriately reflected in asset values where these are impacted by future cash flows and associated sensitivity disclosures (see notes 2(a) Basis of preparation), following the requirements of UK adopted international accounting standards. As part of this evaluation, we performed our own risk assessment , supported by our climate change internal specialists, to determine the risks of material misstatement in the financial statements from climate change which needed to be considered in our audit. We also challenged the Directors’ considerations of climate change risks in their assessment of going concern and viability and associated disclosures. Where considerations of climate change were relevant to our assessment of going concern, these are described above. Based on our work we have not identified the impact of climate change on the financial statements to be a key audit matter or to impact a key auditmatter. Key audit matters Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of the current period and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we identified. These matters included those which had the greatest effect on: the overall audit strategy, the allocation of resources in the audit; and directing the efforts of the engagement team. These matters were addressed in the context of our audit of the financial statements as a whole, and in our opinion thereon, and we donot provide a separate opinion on these matters. 177Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Risk Our response to the risk Key observations communicated to the Audit Committee Revenue recognition across the group’s operations in relation to accrued income relating to measured supplies (2024: £157.4 million, 2023: £132.8 million) Refer to the Audit Committee Report (page 139); Accounting policies (page 193); and Note 22 of the Consolidated Financial Statements (page 215) The Group’s revenue streams relate to the provision of water and sewerage services by South West Water, Pennon Water Services and Sutton and East Surrey Group Holdings. ISAs (UK & Ireland) presume there is a risk of fraud relating to revenue recognition. For the Group, given targets associated with financial performance and pressures to meet market expectations, there is an incentive to overstate revenue. This risk over revenue recognition specifically arises in the following judgemental areas, where there is opportunity to overstate revenue. Income from measured water services requires an estimation of the amount of unbilled charges at the period end. This is calculated using a combination of system generated information, based on previous customer volume usage and the last meter reading date, together with management judgements for a number of different factors not included in the system generated accrual, such as seasonality and operational data trends regarding consumption. The risk remained consistent in the currentyear. Procedures to respond to this risk were performed by the component teams. We obtained an understanding of the process, by performing walkthroughs of the supply of measured services, meter reading and related billing in order to assess the completeness of adjustments to reflect the accrual or deferral of revenue at the year-end; For the South West Water operations, we tested key controls linked to system generated information and around the estimation process for measured revenue; For the South West Water operations, we obtained internal and external data on factors that influence demand from customers, weather patterns and leaks in infrastructure networks and formed an expectation of the impact of these matters on revenue to compare to assumptions used in management’s estimate; For the South West Water and Pennon Water Services operations, we obtained a system report of invoices raised post year end based on actual meter readings taken since the year end. We selected a sample of items from the report to compare to supporting evidence. We compared this report to the year end assumptions used to accrue income for these customer accounts, to assess the reliability of the assumptions used to determine accrued income. For Sutton and East Surrey, we performed an analysis by comparing the accrued revenue to the bills raised post year-end for all customers and tested a sample of customers. We performed analytical procedures by comparing revenue balances for the year against expectations and obtained support for significant variances; We used data analytics to understand the journal entries posted as part of the revenue, trade receivables and accrued income to cash collection process to identify transactions that were outside of our expectation and agreed these to underlying supporting documentation and business rationale; In performing our journal testing, we paid increased attention to entries impacting revenue, focusing on non-system postings and those raised in the last two weeks of the year. We concluded that the estimation process undertaken by management to calculate the measured income accrual reflected latest operational factors in the key assumptions and that the income accrual was appropriately determined. Independent Auditor’s report to the members of Pennon Group plc continued 178 Annual Report and Accounts 2024 « Pennon Group plc Risk Our response to the risk Key observations communicated to the Audit Committee Valuation of the expected credit loss provision for customer balances across the Group (2024: £125.3 million, 2023: £106.5 million) Refer to the Audit Committee Report (page 139); Accounting policies (page 195); and Note 22 of the Consolidated Financial Statements (page 215) The expected credit loss provision is calculated using a combination of system generated information on historic debt recovery rates and management’s judgement of the future likely recovery rates. There is a risk that the assumptions, used by management in calculating the expected credit loss provision, may be susceptible tomanagement bias and the valuation of theprovision against customer balances maybe misstated. Management’s key assumptions include: • that the historic level of collections is indicative of the ability to collect at the same levels in the future; and • that the risk of non-recovery from customers varies, depending on factors such as whether the household customer no longer occupies a property in the area, has previously paid/not paid, is/is not on a payment plan etc., and for non-household customers depends on the general economic performance of the business sector they operate within. In particular, the ongoing cost of living crisis has had a significant impact on the economy and the customers of the Group, which increases the risk relating to recovery of customer balances. The risk has remained consistent in the current year. Procedures to respond to this risk were performed by the component teams. We performed a walkthrough of the process for calculating the expected credit loss provision and assessed the design effectiveness of the key controls; For the South West Water operations, for the debt relating to household customers, we tested operating effectiveness of key controls over billing systems and integrity of data and the reports utilised to generate the ageing and categorisation of debt within the component’s billing systems. For debt relating to non- household customers, we tested the accuracy of data and reports by obtaining underlying evidence to support the parameters reliedupon by management in calculating the expected credit lossprovision; We tested latest information on collection rates and evaluated howthis data was used in the preparation of the expected credit loss provision; For the South West Water and Sutton and East Surrey operations, we utilised collection trends to determine our own range of the likely ultimate collection of debts existing at the balance sheet date, including performing several scenario analyses and compared these to the provision recorded by management, including assessing assumptions for evidence of management bias; We assessed the assumptions used by management in determining amounts provided against different categories and age of debt, by comparing these assumptions to historic collection rates and by considering the impact of changes in the methods adopted operationally by management to collect debt, and in the external environment; For the South West Water and Pennon Water Services operations, we considered whether historic collection performance evidenced behaviour patterns assumed by management depending on categorisation of household and business sector for non- household customers; For the South West Water operations, for debt relating to household customers, we utilised collection information over previous periods, with sensitivities to consider the impact of a deterioration which might arise from a downturn in the economy, to determine an acceptable range of the likely ultimate collection of debts existing at the balance sheet date and compared this to the provision recorded by management; For the South West Water and Pennon Water Services operations, for debt relating to non-household customers, we tested management’s segmentation by business sector and risk factors considered for each sector, regarding non-recovery of debt. We compared this analysis with information on actual collections, by sector, in the current year and since the balance sheet date; and We tested the appropriateness of journal entries and adjustments impacting the expected credit loss provision, particularly those raised close to the balance sheet date. We concluded that the expected credit loss provision of £125.3 million is within an acceptable range and reflects the recent history of collection of outstanding debts and considerations of the impact on future collections from the current macroeconomic environment. 179Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Risk Our response to the risk Key observations communicated to the Audit Committee Capitalisation of costs relating to the capital programme (2024: £604.5 million, 2023: £353.7 million) Accounting policies (page 194); and Note 17 of the Consolidated Financial Statements (page 210) The group has a substantial capital programme which has been agreed with Ofwat and therefore incurs significant annual expenditure in relation to the development and maintenance of both infrastructure and non-infrastructure assets. There is judgement involved in allocation of costs between operating and capital expenditure given the nature of certain projects which include both repairs and maintenance as well as asset enhancement. Therefore, there is a potential for misstatement between the income statement and the statement of financial position. In addition, internal expenditure including staff costs to support capital projects is capitalised only if it can be demonstrated that it is directly attributable to the asset, provides probable economic benefit to the company and can be measured reliably. There is a risk that costs capitalised do not meet thesecriteria. Due to the level of judgement involved, wehave determined that there is a potential for fraud through possible manipulation ofthisbalance. The risk is new in the current year due to the increased level of capital spend in the year. Procedures to respond to this risk were performed by the South West Water component team. We performed a walkthrough of the process for capitalising fixed assets and assessed the design effectiveness of the key controls; We evaluated capital and operating or finance costs, and assessed whether these are appropriately classified and recalculated the amounts included as capital additions to ensure they agree with the underlying supporting documentation; For a sample of capitalised additions, we evaluated the appropriateness of the classification as capital by considering the nature of the expenditure with reference to invoice, certificate or timesheets relating to a specific project or asset. We also considered the judgements management applied in capitalising certain staff costs and overheads; We tested a sample of items allocated to expenditure in the income statement and verified whether they are correctly classified by considering the nature of projects i.e., repairs and maintenance or asset enhancement, to which the expenditure relates; We analysed assets commissioned during the year, on a sample basis, and obtained confirmation from project managers of their use in the business; We made inquiries of project managers to gain an understanding of the on-going capital projects of the Group and how costs are reviewed and determined as capital expenditures that meet the Group’s capitalisation policy; We selected a sample of manual journal entries to record additions within fixed assets, which resulted from a credit posting to an operating expenditure account and checked whether the capitalisation of such expense was appropriately authorised and in accordance with the capitalisation policy. We concluded that management has applied the capitalisation policy appropriately in determining the expenditure to be capitalised. Independent Auditor’s report to the members of Pennon Group plc continued 180 Annual Report and Accounts 2024 « Pennon Group plc Our application of materiality We apply the concept of materiality in planning and performing the audit, in evaluating the effect of identified misstatements on the audit and in forming our audit opinion. Materiality The magnitude of an omission or misstatement that, individually or in the aggregate, could reasonably be expected to influence the economic decisions of the users of the financial statements. Materiality provides a basis for determining the nature and extent of our audit procedures. We determined materiality for the Group to be £8.3 million (2023: £7.2 million), which is 5% (2023: 5%) of the group’s earnings before interest, taxes and non-underlying items. We believe that the group’s earnings before interest, taxes and non-underlying items provides us with an appropriate measure of the underlying performance of the group, as this excludes the impact of higher interest costs on the group’s index-linked debt, driven by the significantly higher levels of inflation and is a measure of focus for users of the financial statements. Therefore, given this focus, we consider this is the most appropriate basis to use for calculating materiality. We determined materiality for the Parent Company to be £8.9 million (2023: £11.0 million), which is 1% (2023: 1%) of equity. We consider that equity is the most appropriate measure given the parent company is an investment holding company with no revenue. Where procedures were performed as part of the group audit, we performed our procedures to the group materiality level which was lower than the Parent Company materiality. During the course of our audit, we reassessed initial materiality using the consolidated results for the year. Based on the materiality measure of underlying earnings before interest and tax, we have updated our Planning Materiality to £8.3 million. Starting basis • Reported earnings before interest and taxes £140.4 million (2023: reported profit before taxation £109.4 million) Adjustments • Non-underlying items (refer to Note 6) increase basis by £25.9 million (2023: £43.7 million increase) Materiality • Totals £166.3 million earnings before interest, taxes and non-underlying items (2023: £153.1 million earnings before interest, taxes and non-underlying items) • Materiality of £8.3 million (2023: £7.2 million) (5% of earnings before interest, taxes and non-underlying items) (2023: 5% of earnings before interest, taxes and non-underlying items) 181Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Performance materiality The application of materiality at the individual account or balance level. Itis set at an amount to reduce to an appropriately low level the probability that the aggregate of uncorrected and undetected misstatements exceedsmateriality. On the basis of our risk assessments, together with our assessment of the Group’s overall control environment, our judgement was that performance materiality was 75% (2023: 75%) of our planning materiality, namely £6.2 million (2023: £5.4 million). We have set performance materiality at this percentage based on our assessment of the group’s internal control environment and the extent and nature of audit findings identified in the prior period. This basis isconsistent with prior year. Audit work at component locations for the purpose of obtaining audit coverage over significant financial statement accounts is undertaken based on a percentage of total performance materiality. The performance materiality set for each component is based on the relative scale and risk of the component to the Group as a whole and our assessment of the risk of misstatement at that component. In the current year, the range of performance materiality allocated to components was £1.3 million to £5.6 million (2023: £1.6 million to £4.8 million). Reporting threshold An amount below which identified misstatements are considered as being clearly trivial. We agreed with the Audit Committee that we would report to them all uncorrected audit differences in excess of £0.4 million (2023: £0.4 million), which is set at 5% of planning materiality, as well as differences below that threshold that, in our view, warranted reporting on qualitative grounds. We evaluate any uncorrected misstatements against both the quantitative measures of materiality discussed above and in light of other relevant qualitative considerations in forming our opinion. Other information The other information comprises the information included in the annual report set out on pages 1 to 174 and 239 to 247, other than the financial statements and our auditor’s report thereon. The directors are responsible for the other information contained within the annual report. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in this report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of the other information, weare required to report that fact. We have nothing to report in this regard. Opinions on other matters prescribed by the Companies Act 2006 In our opinion, the part of the directors’ remuneration report to be audited has been properly prepared in accordance with the Companies Act 2006. In our opinion, based on the work undertaken in the course of the audit: • the information given in the strategic report and the directors’ report for the financial year for which the financial statements are prepared is consistent with the financial statements; and • the strategic report and the directors’ report have been prepared in accordance with applicable legal requirements. Independent Auditor’s report to the members of Pennon Group plc continued 182 Annual Report and Accounts 2024 « Pennon Group plc Matters on which we are required to report by exception In the light of the knowledge and understanding of the group and the parent company and its environment obtained in the course of the audit, we have not identified material misstatements in the strategic report or the directors’report. We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion: • adequate accounting records have not been kept by the parent company, or returns adequate for our audit have not been received from branches not visited by us; or • the parent company financial statements and the part of the Directors’ Remuneration Report to be audited are not in agreement with the accounting records and returns; or • certain disclosures of directors’ remuneration specified by law are not made; or • we have not received all the information and explanations we require forour audit Corporate Governance Statement We have reviewed the directors’ statement in relation to going concern, longer-term viability and that part of the Corporate Governance Statement relating to the group and company’s compliance with the provisions of the UK Corporate Governance Code specified for our review by the Listing Rules. Based on the work undertaken as part of our audit, we have concluded that each of the following elements of the Corporate Governance Statement is materially consistent with the financial statements or our knowledge obtained during the audit: • Directors’ statement with regards to the appropriateness of adopting the going concern basis of accounting and any material uncertainties identified set out on page 172; • Directors’ explanation as to its assessment of the company’s prospects, the period this assessment covers and why the period is appropriate set out on page 65; • Director’s statement on whether it has a reasonable expectation that the group will be able to continue in operation and meets its liabilities set out on page 172; • Directors’ statement on fair, balanced and understandable set out on page174; • Board’s confirmation that it has carried out a robust assessment of the emerging and principal risks set out on page 55; • The section of the annual report that describes the review of effectiveness of risk management and internal control systems set out on page 55; and; • The section describing the work of the audit committee set out on page136. Responsibilities of directors As explained more fully in the directors’ responsibilities statement set out on page 174, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the directors are responsible for assessing the group and parent company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the group or the parent company or to cease operations, or have no realistic alternative but to do so. Auditor’s responsibilities for the audit of the financial statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. Explanation as to what extent the audit was considered capable of detecting irregularities, including fraud Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect irregularities, including fraud. The risk of not detecting a material misstatement due to fraud is higher than the risk of not detecting one resulting from error, as fraud may involve deliberate concealment by, for example, forgery or intentional misrepresentations, or through collusion. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below. However, the primary responsibility for the prevention and detection of fraud rests with both those charged with governance of the company and management. • We obtained an understanding of the legal and regulatory frameworks that are applicable to the group and determined that the most significantare; • Companies Act 2006 • Financial Reporting Council (FRC) and the UK Corporate GovernanceCode • Tax legislation (governed by HM Revenue & Customs) • Health and Safety legislation • Environment Agency environmental permits • Ofwat regulations • UK listing rules 183Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information • We understood how Pennon Group plc is complying with those frameworks by reading internal policies and codes of conduct and assessing the entity level control environment, including the level of oversight of those charged with governance. We made enquiries of the group’s legal counsel, regulatory team and internal audit of known instances of non-compliance or suspected non-compliance with laws and regulations. We corroborated our enquiries through review of correspondence with regulatory bodies. We designed our audit procedures to identify non-compliance with such laws and regulations identified in the paragraph above. As well as enquiry and attendance at meetings, our procedures involved a review of the reporting to the above committees and a review of board meetings and other committee minutes to identify any non-compliance with laws and regulations. Our procedures also involved journal entry testing, with a focus on journals meeting our defined risk criteria based on our understanding of the business. • We assessed the susceptibility of the group’s financial statements to material misstatement, including how fraud might occur by making enquiries of senior management, including the Chief Executive Officer, Chief Financial Officer, Head of Internal Audit and Audit Committee Chair. We planned our audit to identify risks of management override, tested higher risk journal entries and performed audit procedures to address the potential for management bias, particularly over areas involving significant estimation and judgement. Further discussion of our approach to address the identified risks of management override are set out in the key audit matters section of our report. • Based on this understanding we designed our audit procedures to identify non-compliance with such laws and regulations. Our procedures involved making enquiries of key management, those charged with governance and legal counsel, reviewing key policies, inspecting legal registers and correspondence with regulators and reading key management meeting minutes. We involved our internal specialists where appropriate. We also completed procedures to conclude on the compliance of significant disclosures in the Annual Report and Accounts with the requirements of the relevant accounting standards, UK legislation and the UK Corporate Governance Code. • We communicated regularly with the component teams and attended key meetings with the component teams, management and legal counsel in order to identify and communicate any instances of non-compliance with laws and regulations. • The group operates in the water sector which is highly regulated. As such the Senior Statutory Auditor reviewed the experience and expertise of the engagement team to ensure that the team had the appropriate competence and capabilities, which included the use of specialists whereappropriate. A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council’s website at https://www.frc.org.uk/ auditorsresponsibilities. This description forms part of our auditor’s report. Other matters we are required to address • Following the recommendation from the audit committee, we were appointed by the company on to audit the financial statements for the year ending 31 March 2015 and subsequent financial periods. • The period of total uninterrupted engagement including previous renewals and reappointments is 10 years, covering the years ending 31 March 2015 to 31 March 2024. • The audit opinion is consistent with the additional report to the auditcommittee. Use of our report This report is made solely to the company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the company’s members those matters we are required to state to them in an auditor’s report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the company’s members as a body, for our audit work, for this report, or for the opinions we have formed.

form part of these financial statements. 190 Annual Report and Accounts 2024 « Pennon Group plc Notes to the Financial Statements 1. General information Pennon Group plc is a company registered in the United Kingdom under the Companies Act 2006. The address of the registered office is given on page 246. Pennon Group’s business is operated through its principal subsidiaries. South West Water Limited, provides water and wastewater services in Devon, Cornwall and parts of Dorset and Somerset and water only services in parts of Dorset, Hampshire, Wiltshire and Bristol. Pennon Group is the majority shareholder of Pennon Water Services Limited, a company providing water and wastewater retail services to non- household customer accounts across Great Britain. Bristol Water Holdings Limited owns a 30% share in Water 2 Business Limited, a joint venture with Wessex Water, operating in the same sector as Pennon Water Services Limited. On 10 January 2024, the Company acquired 100% of the issued capital of Sumisho Osaka Gas Water UK Limited (which has subsequently been renamed Sutton and East Surrey Group Holdings Limited), the holding company of Sutton and East Surrey Water plc (“SES Water”) and Sutton and East Surrey Water Services (“SESWS”) a company providing water and wastewater retail services to non-household customer accounts along with certain other ancillary businesses, for £90.2 million from Sumitomo Corporation and Osaka Gas. SES Water is a regulated water only company serving a population of approximately 750,000 customers in the South East region. On 8 January 2024, an Initial Enforcement Order (IEO) was issued by the Competition and Markets Authority (CMA) regarding the Group's acquisition of Sutton and East Surrey Group Holdings Limited (SES). The IEO did not prevent the Group from completing its acquisition of SES, but required Pennon and SES to remain operationally separate, and in the form in which each had existed prior to the IEO coming into force, until the completion of the CMA’s review. The Group duly completed its acquisition of SES on 10 January 2024. The Group has been exposed to the variable returns from the results and performance of SES since that date. The CMA has granted a number of derogations to the IEO in order to permit the Group oversight of SES’ activities, for the purposes of, among other things, maintaining SES’ financial position and ensuring that the Group as whole (including SES) is able to comply with its corporate governance obligations. These include derogations granted on 9 January 2024 allowing the Group to exercise its rights as shareholder in connection with certain reserved matters, to require SES to appoint individuals to certain internal management functions, and to nominate an observer to attend meetings of SES’ board of directors. On 3 May 2024 the Group offered to provide separate reporting information for Sutton and East Surrey Water plc from the rest of the Group’s water businesses post-Merger to allow Ofwat the ability to make comparisons between water enterprises, a similar remedy was accepted by the CMA following the acquisition of Bristol Water plc in 2021. The CMA considers that there are reasonable grounds for believing that the undertakings offered by the Group, or a modified version of them, might be accepted by the CMA. The Group therefore remains reasonably certain that approval of the acquisition will be granted in the coming months. The Group has considered the requirements of IFRS 10 Consolidated Financial Statements and – in light of the foregoing – has determined that Pennon Group plc should consolidate SES’ results within the Group’s financial statements for the year ended 31 March 2024 as from the date of the acquisition, i.e. 10 January 2024. The impact of consolidating SES from this date is disclosed in note 43. 2. Principal accounting policies The principal accounting policies adopted in the preparation of these financial statements are set out below. These policies have been consistently applied to the years presented. (a) Basis of preparation These financial statements have been prepared on the historical cost accounting basis (except for fair value items, principally acquisitions, transfers of assets from customers and certain financial instruments as described in accounting policy notes (b), (u) and (n) respectively) and in accordance with UK-adopted international accounting standards and, as regards the parent company financial statements, as applied in accordance with the provisions of the Companies Act 2006. The Company has taken advantage of section 408 of the Companies Act 2006 not to present the parent company profit and loss account. These financial statements are presented in pounds sterling and all values rounded to the nearest one-hundred thousand pounds, except when otherwise indicated. A summary of the principal accounting policies is set out below, together with an explanation where changes have been made to previous policies on the adoption of new accounting standards and interpretations in the year. The going concern basis has been adopted in preparing these financial statements. At 31 March 2024 the Group has access to undrawn committed funds and cash and cash deposits totalling £601.4 million, including cash and other short-term deposits of £171.4 million and £430.0 million of undrawn facilities. Cash and other short-term deposits include £26.0 million of restricted funds deposited with lessors which are available for access, subject to being replaced by an equivalent valued security. Considering this the Group has a headroom of £435 million, including the impact of £98 million of loans and facilities due for maturity or renewal within the going concern period through to 31 May 2025. In making their assessment, the Directors reviewed the principal risks and considered which risks might threaten the Group’s going concern status, to do this the Group’s business plan has been stress-tested. Whilst the Group’s risk management processes seek to mitigate the impact of principal risks as set out on pages 55 to 64, individual sensitivities against these risks have been identified. These sensitivities, which are ascribed a value with reference to risk weighting, factoring in the likelihood of occurrence and financial impact, were applied to the baseline financial forecast which uses the Group’s annual budget for FY 2024/25, including the impact of the acquisition of Sutton and East Surrey Group Holdings Limited, and longer-term strategic business plan for the remainder of the going concern period to 31 May 2025. The risks and sensitivities include consideration of: legislative impacts such as change in government policy and non-compliance with laws and regulations, macro-economic impacts such as inflation and interest rate increases, regulatory impacts such as the ongoing Ofwat price and tariff review, i.e. PR24, covering the period from April 2025 to March 2030, and operational impacts such as ensuring adequate water resources and failure of operational assets. A combined stress testing scenario has been performed to assess the overall impact of these individual scenarios impacting the Group collectively. The combined weighted impact of the risks occurring is c.£80 million, this value is considered equivalent to an extreme one-off event that could occur within a year, the probability of such an event happening is deemed unlikely. Through this testing, it has been determined that none of the individual principal risks would in isolation, or in aggregate, compromise the going concern of the Group over the going concern period, the assessment has been considered by reviewing the impact on the solvency position as well as debt and interest covenants. In the combined scenario to ensure that the Group was able to continue as a going concern, additional mitigations could be deployed to reduce gearing and increase covenant headroom. In the combined stress test scenario, the group has sufficient liquidity and covenant headroom which reflects that no mitigations would be needed by the Group. However if required additional mitigations could be deployed to reduce gearing and increase covenant headroom. Examples of mitigations could include: reduction in discretionary operational expenditure, deferral of capital expenditure and/or cancellation of non-essential capital expenditure, reduction in the amount of dividend payable, and raising additional funding. 191Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 2. Principal accounting policies continued In addition, we have modelled a reverse engineered scenario that could possibly compromise the Group’s solvency over the going concern assessment period. This scenario builds on the factors above and additionally assumes all the Group’s principal risks are incurred within the going concern period, with no probability weightings attached. The Board considered the likelihood of this scenario on the Group’s solvency over the going concern period as remote, given this would require all of the principal risks to be incurred at maximum impact within the same time frame, without implementing controllable mitigations, as noted above, or raising additional funding. We have considered the Group’s funding position and financial projections, which take into account a range of possible impacts, including the refinancing required within and immediately after the going concern assessment period. Subsequent to the year end date, the Group has secured a £150 million private placement and a £350 million liquidity facility, which reflects on the Group’s ability to secure finance. Having considered these factors, the Directors have a reasonable expectation that that the Group will meet the requirements of its covenants and has adequate resources to continue in operational existence for the period to at least the end of the going concern assessment period of 31 May 2025, and that there are no material uncertainties to disclose. For this reason, they continue to adopt the going concern basis in preparing the financial statements. In preparing the financial statements management has considered the impact of climate change, taking into account the relevant disclosures in the Strategic Report, including those made in accordance with the recommendations of the Taskforce on Climate-related Financial Disclosure. The expected environmental impact of climate change on the water business has been modelled noting that the physical risks are increasing. It is likely that the Group will need to invest to protect certain assets such as sewage works and pumping stations against sea level inundation and these considerations form part of the planning process for new capital expenditure. Longer term investment, outlined in the strategic plans, will be needed to manage future risks. To achieve this, combined regulatory and government support within their policy frameworks will be essential. Whilst it is estimated additional spend will be required to manage future risks, the current available information and assessment did not identify any risks regarding the sufficiency of funds available to the Group to support this additional spend or any risk that would require the useful economic lives of assets to be reduced in the year or identify the need for impairment that would impact the carrying values of such assets or have any other impact on the financial statements. The impact assessments will be continuously updated to reflect the latest available information on the impact of climate change. New standards or interpretations which were mandatory for the first time in the year beginning 1 April 2023 did not have a material impact on the net assets or results of the Group and the parent company. New standards or interpretations due to be adopted from 1 April 2024 are not expected to have a material impact on the Group’s and the parent company’s net assets or results. Existing borrowing covenants are not impacted by changes in accounting standards. Prior period restatement (parent company cash flow statement) Management considered the FRC’s (Financial Reporting Council’s) Annual Review of Corporate Reporting 2022/2023 published in October 2023 and performed a review of the parent company statement of cash flow. Management review has identified that £73.1 million of loan extended to subsidiary had been incorrectly classified within cash flows from operating activities as opposed to cash flows from investing activities. As such the prior period parent company statement of cash flow in respect of the “Cash generated/(outflow) from operations” and “Net cash generated/(outflow) from operating activities” have been restated from £38.9 million cash outflow to a cash inflow of £34.2 million and £46.0 million cash outflow to a cash inflow of £27.1 million respectively. Furthermore, cash flow from “Loans to subsidiary undertakings” has increased from £nil to a cash outflow of £73.1 million and “Net cash (used in)/received from investing activities” of £21.8 million cash inflow has decreased to a cash outflow of £51.3 million. In addition to this within Note 37 “Analysis of cash flows given in the statement of cash flows” the prior period amounts relating to “Decrease/(increase) in trade and other receivables” of £31.0 million cash outflow has decreased to a cash inflow of £42.1 million and amounts in respect of “Cash generated/(outflow) from operations” of £38.9 million cash outflow has decreased to a cash inflow of £34.2 million. There is no other impact on the parent company balance sheet or statement of changes in equity. (b) Basis of consolidation The Group financial statements include the results of Pennon Group plc and its subsidiaries and joint ventures. The results of subsidiaries and joint ventures are included from the date of acquisition or incorporation and excluded from the date of disposal. The results of subsidiaries are consolidated where the Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The results of joint ventures are accounted for on an equity basis. Intra-group trading, loan balances and transactions are eliminated on consolidation. The acquisition method of accounting is used to account for the purchase of subsidiaries. The excess of the value transferred to the seller in return for control of the acquired business, together with the fair value of any previously held equity interest in that business over the Group’s share of the fair value of the identifiable net assets, is recorded as goodwill. 192 Annual Report and Accounts 2024 « Pennon Group plc 2. Principal accounting policies continued (c) Revenue recognition Group revenue is recognised following delivery of performance obligations and an assessment of when control over the product or service is transferred to the customer. Revenue is only recognised when collection of consideration is highly probable. Revenue is recognised either when the performance obligation in the contract has been performed (point in time recognition) or ‘over time’ as the performance obligations to the customer are satisfied. For each obligation satisfied over time, the Group applies a revenue recognition method that accurately reflects performance in transferring control of the services to the customer. Where a contract with a customer includes more than one performance obligation, revenue is allocated to each obligation in proportion to a fair value assessment of the total contract sales value split across the services provided. At the inception of a contract the total transaction price is estimated, being the fair value to which the Group expects to be entitled under the contract, including any variable consideration. Variable consideration is based on the most likely outcome of the performance obligations. Revenue excludes value added tax, trade discounts and revenue arising from transactions between Group companies. Water (domestic and non-household retail) For most of the services provided to domestic customers, contract terms are implied through statute and regulation in the absence of formal, written contracts. South West Water and SES Water have a duty under legislation to provide domestic customers with services regardless of payment and are not permitted to disconnect domestic customers for non-payment of bills. Charges are set via the periodic review price-setting process, regulated by Ofwat. In respect of ongoing, continuous services to customers, such as the provision of drinking water and wastewater services, revenue is recognised over time. Customers with an unmeasured supply are billed at the start of the year for the full amount of the annual charge but typically take advantage of a choice of payment arrangements to pay by regular instalments. The performance obligation has been assessed as standing ready to provide water and sewerage services when required by our customers, and accordingly revenue is recognised under IFRS 15 as the stand-ready obligation is fulfilled over time. Customers with a metered supply are sent up to four bills per year, based either on actual meter readings or estimated usage. For these customers, revenue includes an estimation of the amount of unbilled usage at the period end. Payment options for domestic customers include an annual meter payment plan where customers agree to pay a fixed amount per month which is adjusted to reflect actual consumption at the end of the year. Revenue is recognised as water is supplied, based on estimate usage for unbilled elements. A range of regulated services is offered to property developers and owners who require connection to the water and sewerage networks or need the networks to be extended or altered. Typically, these customers pay an estimate of the charges in advance as a deposit, which is treated as a contract liability and are billed or refunded the difference between the estimate and actual costs on completion of the work. The principle components of these contributions are as follows: i) Where the performance obligation relates solely to a connection to the network, revenue is recognised at the point of connection when the customer is deemed to obtain control. ii) Where assets are constructed or provided by the Group or assets transferred to the Group, it is considered that there is an explicit or implied performance obligation to provide an ongoing water and/or wastewater service, with the result that revenue is recognised over a time no longer than the economic life of assets provided by or transferred to the Group. Pennon Water Services provides specialist retail water and wastewater services to business customers. It raises bills and recognises revenue in accordance with its contracts with customers and in line with the limits established for the non-household periodic price-setting process where applicable. Contract assets and liabilities A trade receivable is recognised when the Group has an unconditional right to receive consideration in exchange for performance obligations already fulfilled. A contract asset is recognised when the Group has fulfilled some of its performance obligations but has not yet obtained an unconditional right to receive consideration. The amounts for contract assets, when applicable, are disclosed within note 19 (Other non-current assets) and note 22 (Trade and other receivables) as appropriate. A contract liability is recognised when consideration is received in advance of the Group performing its performance obligations to customers, including, when appropriate, transfers of assets from customers (per paragraph (u) below). The value of contract liabilities is disclosed within note 26 (Trade and other payables) and note 29 (Other non-current liabilities) as appropriate. (d) Segmental reporting Each of the Group’s business segments provides services which are subject to risks and returns which are different from those of the other business segments. The Group’s internal organisation and management structure and its system of internal financial reporting are based primarily on business segments. The Group is organised into two operating segments. The water segment comprises the regulated water and wastewater services undertaken by South West Water and the regulated water services undertaken by SES Water. The non-household retail business reflects the services provided by Pennon Water Services and SESWS. Other segments, including Pennon Group plc, are not reportable segments as they are not reported to Chief Decision makers. Segmental revenue and results include transactions between businesses. Inter-segmental transactions are eliminated on consolidation. (e) Goodwill Goodwill arising on consolidation from the acquisition of subsidiary undertakings represents the excess of the purchase consideration over the fair value of net assets acquired, less any subsequent impairment charges. Goodwill is recognised as an asset and reviewed for impairment at least annually. Any impairment is recognised immediately in the income statement and is not subsequently reversed. For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the cash generating units (CGUs) or group of CGUs, that is expected to benefit from the synergies of the combination. Each unit or group of units to which goodwill is allocated represents the lowest level within the entity at which the goodwill is monitored for internal reporting purposes. Goodwill is allocated and monitored at the reportable operating segment level. Further details are contained in accounting policy (i). When a subsidiary undertaking is sold, the profit or loss on disposal is determined after including the attributable amount of goodwill. 193Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 2. P rincipal accounting policies continued (f) Other intangible assets Other intangible assets include assets acquired in business combination and are capitalised at fair value at the date of acquisition. Following initial recognition, finite life intangible assets are amortised on a straight- line basis over their estimated useful lives, with the expense charged to the income statement through operating costs. (g) Property, plant and equipment i) Infrastructure assets (being water mains and sewers, impounding and pumped raw water storage reservoirs, dams, pipelines and sea outfalls) Infrastructure assets were included at fair value on transition to IFRS, and subsequent additions are recorded at cost less accumulated depreciation and impairment charges. Expenditure to increase capacity or enhance infrastructure assets is capitalised where it can be reliably measured, and it is probable that incremental future economic benefits will flow to the Group. The cost of day to day servicing of infrastructure components is recognised in the income statement as it arises. Infrastructure assets are depreciated evenly over their useful economic lives, and are principally: Dams and impounding reservoirs 100 to 200 years Water mains 60 to 180 years Sewers 75 to 150 years Assets in the course of construction are not depreciated until commissioned. ii) Other assets (being property, overground plant and equipment) Other assets are included at cost less accumulated depreciation. Freehold land is not depreciated. Other assets are depreciated evenly to their residual value over their estimated economic lives, and are principally: Land and buildings – freehold 10 to 80 years buildings Land and buildings – leasehold Over the estimated economic lives buildings or the lease period, whichever is the shorter Operational properties 15 to 100 years Fixed plant 10 to 30 years Vehicles, mobile plant and computers 4 to 20 years Assets in the course of construction are not depreciated until commissioned. The cost of assets includes directly attributable labour and overhead costs which are incremental to the Group. Borrowing costs directly attributable to the construction of a qualifying asset (an asset necessarily taking a substantial period of time to be prepared for its intended use) are capitalised as part of the asset. Assets transferred from customers are recognised at fair value as set out in accounting policy (u). The assets’ residual values and useful lives are reviewed annually. Gains and losses on disposal are determined by comparing sale proceeds with carrying amounts. These are included in the income statement. (h) Leased assets All are accounted for by recognising a right-of-use asset and a lease liability except for: • Low value assets; and • Leases with a duration of 12 months or less. Contracts are initially measured at the present value of contractual payments due to the lessor over the lease term, with the discount rate determined by reference to the rate inherent in the lease unless this is not readily determinable, in which case the Group’s incremental borrowing rate on commencement of the lease is used. After initial measurement, lease payments are allocated between the liability and finance cost. The finance cost is charged to profit and loss over the lease period to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The interest element of cash payments in respect of these leases is included within interest payments in determining net cash generated from operating activities. The capital element of the cash payment is included within cash flows from financing activities. Right-of- use assets are amortised on a straight-line basis over the remaining term of the lease or the remaining economic life of the asset if shorter. When the Group revisits its estimate of lease term (because, for example, it reassesses an extension option), it adjusts the carrying amount of the lease liability to reflect the payments to make over the revised term, which is discounted at the same discount rate that applied on lease commencement. In these circumstances an equivalent adjustment is made to the carrying value of the right-of-use asset, with the revised carrying amount being amortised over the remaining (revised) lease term. Assets are included as property, plant and equipment as right-of-use assets at the present value of the minimum lease payments and are depreciated over their estimated economic lives or the finance lease period, whichever is the shorter. The corresponding liability is recorded as borrowings. The interest element of the rental costs is charged against profits using the actuarial method over the period of the lease. The Group regularly uses sale and leaseback transactions to finance its capital programme. A sale and leaseback transaction is where the Group sells an asset and immediately reacquires the use of the asset by entering into a lease with the buyer. Each transaction is assessed as to whether it meets the criteria within IFRS 15 ‘Revenue from contracts with customers’ for a sale to have occurred. If the sale criteria are met a lease liability is recognised, the associated property, plant and equipment asset is derecognised, and a right-of-use asset is recognised at the proportion of the carrying value relating to the right retained. Any gain or loss arising relates to the rights transferred to the buyer. If the criteria for a sale under IFRS 15 have not been met the asset is not derecognised and no sale is recorded. (i) Impairment of non-financial assets Assets with an indefinite useful life are not subject to amortisation and are tested annually for impairment, or whenever events or changes in circumstance indicate that the carrying amount may not be recoverable. Assets subject to amortisation or depreciation are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised for the amount by which an asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value, less costs to sell, and value- in-use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (CGUs). Value-in-use represents the present value of projected future cash flows expected to be derived from a CGU, discounted using a pre- tax discount rate which reflects an assessment of the market cost of capital of the CGU. Impairments are charged to the income statement in the year in which they arise. Non-financial assets other than goodwill that have been impaired are reviewed for possible reversal of the impairment at each reporting date. Where a previously impaired asset or CGU’s recoverable amount is in excess of its carrying amount, previous impairments are reversed to the carrying value that would have expected to be recognised had the original impairment not occurred. (j) Parent company: Investment in subsidiary undertakings Investments in subsidiary undertakings are initially recorded at cost, being the fair value of the consideration paid. Subsequently investments are reviewed for impairment on an individual basis annually or if events or changes in circumstances indicate that the carrying value may not be fully recoverable. (k) Investment in associated companies Associated companies are entities over which the Group exercises joint control. Investments in associated companies are accounted for using the equity method of accounting. Any excess of the cost of acquisition over the Group’s share of the fair values of the identifiable net assets of the associated company at the date of acquisition is recognised as goodwill and is included in the carrying value of the investment in the associated company. 1 94 Annual Report and Accounts 2024 « Pennon Group plc 2. Principal accounting policies continued The carrying value of the Group’s investment is adjusted for the Group’s share of post-acquisition profits or losses recognised in the income statement and statement of comprehensive income. Losses of an associated company in excess of the Group’s interest are not recognised unless the Group has a legal or constructive obligation to fund those losses. (l) Inventories Inventories are stated at the lower of cost and net realisable value. The cost of finished goods and work in progress includes raw materials and the cost of bringing stocks to their present location and condition. It excludes borrowing costs. Net realisable value is the estimated selling price less cost to sell. The costs of items of inventory are determined using weighted average costs. (m) Cash and cash deposits Cash and cash deposits comprise cash in hand and short-term deposits held at banks. Bank overdrafts are offset against cash balances where there is a legally enforceable right to offset and there is an intention to settle the balances on a net basis. Otherwise, overdrafts are included within current borrowings. (n) Financial instruments Financial instruments are recognised and measured in accordance with IFRS 9. The Group classifies its financial instruments in the following categories: i) Debt instruments at amortised cost All loans and borrowings are initially recognised at fair value, net of transaction costs incurred. Following initial recognition, interest-bearing loans and borrowings are subsequently stated at amortised cost using the effective interest method. Gains and losses are recognised in the income statement when instruments are derecognised or impaired. Premia, discounts and other costs and fees are recognised in the income statement through amortisation. Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date. ii) Trade receivables Trade receivables do not carry any interest receivable and are recognised initially at fair value and subsequently at amortised cost using the effective interest method, less provision for expected credit losses (ECLs). In accordance with IFRS 9, each Group entity performs an impairment analysis at each reporting date to measure the ECLs. Each entity does not track changes in credit risk but instead recognises a loss allowance based on lifetime ECLs at each reporting date. Each subsidiary has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the receivables and the economic environment. iii) Trade payables Trade payables are not interest-bearing and are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method. iv) Derivative financial instruments and hedging activities The Group uses derivative financial instruments, principally interest rate swaps, cross-currency interest rate swaps and inflation swaps to hedge risks associated with interest rate and exchange rate fluctuations. Derivative instruments are initially recognised at fair value on the date the derivative contract is entered into and subsequently remeasured at fair value for the reported balance sheet. The Group designates certain hedging derivatives as either: • A hedge of a highly probable forecast transaction or change in the cash flows of a recognised asset or liability (a cash flow hedge); or • A hedge of the exposure to change in the fair value of a recognised asset or liability (a fair value hedge). The gain or loss on remeasurement is recognised in the income statement except for cash flow hedges which meet the conditions for hedge accounting, when the portion of the gain or loss on the hedging instrument which is determined to be an effective hedge is recognised directly in equity, and the ineffective portion in the income statement. The gains or losses deferred in equity in this way are subsequently recognised in the income statement in the same period in which the hedged underlying transaction or firm commitment is recognised in the income statement. In order to qualify for hedge accounting, the Group is required to document in advance the relationship between the item being hedged and the hedging instrument. The Group is also required to document and demonstrate an assessment of the relationship between the hedged item and the hedging instrument which shows that the hedge will be highly effective on an ongoing basis. This effectiveness testing is reperformed at the end of each reporting period to ensure that the hedge remains highly effective. The full fair value of a hedging derivative is apportioned on a straight- line basis between non-current and current assets and liabilities based on the remaining maturity of the hedging derivative. Derivative financial instruments deemed held for trading, which are not subject to hedge accounting, are classified as a current asset or liability with any change in fair value recognised immediately in the income statement. The Group uses cross-currency swaps for some of its foreign currency denominated private placement borrowings. The swaps either have the effect of (i) converting variable rate foreign currency borrowings into fixed rate sterling borrowings, (ii) converting fixed rate foreign currency borrowings into fixed rate sterling borrowings, or (iii) converting fixed rate foreign currency borrowings into floating rate sterling borrowings . v) Financial instruments at fair value through profit Financial instruments at fair value through profit reflect the fair value movement of the hedged risk on a hedged item through a fair value hedging relationship. The fair values of these financial instruments are initially recognised on the date the hedging relationship is entered into and thereafter remeasured at each subsequent balance sheet date. The gain or loss on remeasurement for the period is recognised in the income statement. vi) Receivables due from subsidiary undertakings Amounts owed by subsidiaries are classified and recorded at amortised cost and reduced by allowances for ECLs. Estimated future credit losses are first recorded on initial recognition of a receivable and are based on estimated probability of default. Individual balances are written off when management deems them not to be collectible. (o) Taxation including deferred tax The tax charge for the year comprises current and deferred tax. Tax is recognised in the income statement, except to the extent that it relates to items recognised in the statement of comprehensive income or directly in equity. In this case the tax is also recognised in the statement of comprehensive income or directly in equity as appropriate. Current tax is calculated on the basis of tax laws enacted or substantively enacted at the balance sheet date. Management periodically evaluates tax items subject to interpretation and establishes provisions on individual tax items, where in the judgement of management, the position is uncertain. The Group includes a number of companies, including the parent company, which are part of a tax group for certain aspects of the tax legislation. One of these aspects relates to group relief whereby current tax liabilities can be offset by current tax losses arising in other companies within the same tax group. Payments for group relief are included within the current tax disclosures. Deferred tax is provided in full on temporary differences between the carrying amount of assets and liabilities in the financial statements and the tax base, except where they arise from initial recognition of an asset or liability in a transaction, other than a business combination, that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred tax assets are recognised only to the extent that it is probable that future taxable profits will be available against which the assets can be realised. Deferred tax is determined using the tax rates enacted or substantively enacted at the balance sheet date, and expected to apply when the deferred tax liability is settled or the deferred tax asset is realised. 195Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 2.

It is unclear if the Pillar Two model rules created additional temporary differences, whether to remeasure deferred taxes for the Pillar Two model rules and which tax rate to use to measure deferred tax. In response to this uncertainty, the IASB and AASB on 23 May 2023 and 27 June 2023, respectively, introduced a mandatory temporary exception to the requirements of IAS12, ‘Income taxes’ under which a company does not recognise or disclose information about deferred tax assets and liabilities relating to the proposed Pillar Two model rules. The Group applied the temporary exception at 31 March 2024. Pillar Two legislation has been enacted in the UK which is the only jurisdiction in which the Group operates. The legislation will be effective for the Group’s financial year beginning 1 April 2024. The Group has performed an assessment of the Group’s potential exposure to Pillar Two income taxes. This assessment is based on the most recent financial information available regarding the financial performance of the constituent entities in the Group. Based on the assessment performed, the Pillar Two effective tax rates in the only jurisdiction in which the Group operates, i.e. the UK is above 15% and management is not currently aware of any circumstances under which this might change. Therefore, the Group does not expect a potential exposure to Pillar Two top-up taxes. (p) Provisions Provisions are made where there is a present legal or constructive obligation as a result of a past event and it is probable that there will be an outflow of economic benefits to settle this obligation and a reliable estimate of this amount can be made. Where the effect of the time value of money is material the current amount of a provision is the present value of the expenditures expected to be required to settle obligations. The unwinding of the discount to present value is included as notional interest within finance costs. (q) Share capital and treasury shares Ordinary shares are classified as equity. Where the Company purchases the Company’s equity share capital (treasury shares) the consideration paid, including any directly attributable costs, is deducted from equity until the shares are cancelled or reissued. Where such shares are subsequently reissued, any consideration received, net of any directly attributable transaction costs, is included in equity. The Group balance sheet includes the shares held by the Pennon Group plc Employee Benefit Trust, relating to employee share-based payments, which have not vested at the balance sheet date. These are shown as a deduction from shareholders’ equity until such time as they vest. Share buy-back scheme and tender offer Shares purchased for cancellation are deducted from retained earnings at the total consideration paid or payable, including any related expenses. Where the Group has an irrevocable commitment to purchase shares for cancellation at the balance sheet date, a liability is recognised in other creditors based on the share price at the balance sheet date and retained earnings reduced by the amount of the liability. Shares purchased and held by the Group (treasury shares) are deducted from the treasury reserve at the total consideration paid or payable. On cancellation of treasury shares, the cost is transferred from the treasury reserve to retained earnings. When treasury shares are issued at below cost, an amount representing the difference between the cost of those shares and issue proceeds is transferred to retained earnings. No gain or loss is recognised in the consolidated income statement on the purchase, sale, issue or cancellation of the Group’s own equity instruments. (r) Dividend distributions Dividend distributions are recognised as a liability in the financial statements in the period in which the dividends are approved by the Company’s shareholders. Interim dividends are recognised when paid, final dividends when approved by shareholders at the Annual General Meeting. (s) Employee benefits i) Retirement benefit obligations The Group operates defined benefit and defined contribution pension schemes. Defined benefit pension schemes The liability recognised in the balance sheet in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the year less the fair value of plan assets. If the value of a plan’s assets exceeds the present value of its obligations, the resulting surplus is only recognised if the Group has an unconditional right to that surplus. The defined benefit obligation is calculated by independent actuaries who advise on the selection of Directors’ best estimates of assumptions, using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds, and that have terms to maturity approximating to the terms of the related pension obligation. The increase in liabilities of the Group’s defined benefit pension schemes, expected to arise from employee service in the year, is charged against operating profit. Changes in benefits granted by the employer are recognised immediately as a past service cost in the income statement. Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity in the statement of comprehensive income in the period in which they arise. Defined contribution scheme Costs of the defined contribution pension scheme are charged to the income statement in the year in which they arise. The Group has no further payment obligations once the contributions have been paid. ii) Share-based payment The Group operates a number of equity-settled, share-based payment plans for employees. The fair value of the employee services required in exchange for the grant is recognised as an expense over the vesting period of the grant. Fair values are calculated using an appropriate pricing model. Non- market-based vesting conditions are adjusted for assumptions as to the number of shares which are expected to vest. (t) Fair values The fair value of interest rate, inflation and cross currency swaps is based on the market price to transfer the asset or liability at the balance sheet date in an ordinary transaction between market participants. The fair values of short-term deposits, loans and overdrafts with a maturity of less than one year are assumed to approximate to their book values. In the case of non-current bank loans and other loans, the fair value of financial liabilities for disclosure purposes is estimated by discounting the future contractual cash flows at the current market interest rate available to the Group for similar financial instruments. (u) Transfers of assets from customers Where an item of property, plant and equipment that must be used to connect customers to the network is received from a customer, or where cash is received from a customer for the acquisition or construction of such an item, that asset is recorded and measured on initial recognition at its fair value. The credit created by the recognition of the asset is recognised as a contract liability on the balance sheet. The contract liability reduces, and revenue is recognised in the income statement, as performance obligations are satisfied. The period over which the credit is recognised depends upon the nature of the service provided, as determined by the agreement with the customer. Where the service provided is solely a connection to the network, the credit is recognised at the point of connection. If the agreement does not specify a period, revenue is recognised over a period no longer than the economic life of the transferred asset used to provide the ongoing service. The fair value of assets on transfer from customers is determined using a cost valuation approach allowing for depreciation. 196 Annual Report and Accounts 2024 « Pennon Group plc 2. Principal accounting policies continued (v) Foreign exchange Transactions denominated in foreign currencies are translated at the exchange rate at the date of the transaction. Monetary assets and liabilities denominated in a foreign currency are translated at the closing balance sheet rate. The resulting gain or loss is recognised in the income statement. (w) Non-underlying items Non-underlying items are those that in the Directors’ view should be separately disclosed by virtue of their size, nature or incidence to enable a full understanding of the Group’s financial performance. (x) Grants and contributions Grants and contributions receivable in respect of property, plant and equipment which provide the customer with ongoing access to the water and sewerage networks, are treated as contract liabilities and released to revenue over the economic life of those elements of property, plant and equipment. Grants and contributions receivable in respect of expenses charged against profits in the year have been included in the income statement. Government grants are recognised where there is reasonable certainty that the grant will be received and all attached conditions will be complied with. When the grant relates to an expense item, it is recognised on a systematic basis over the periods that the related costs, for which it is intended to compensate, are expensed. The income from such grants is presented in the financial statements as a deduction from the expense to which it relates. (y) Variable consideration Variable consideration in connection with the purchase of individual assets outside of business combinations is recognised as a financial liability at fair value when the amount of consideration payable is contingent upon future events that are not within the direct control of the group. Initial recognition of the financial liability is at fair value. Where the variability of the consideration is directly linked to the quality or output of the asset received then any changes in the consideration is recognised by adjusting the carrying amount of the related asset. (z) Acquisitions of groups of assets that do not constitute a business The identifiable assets and liabilities in acquisitions of groups of assets that do not constitute a business, initially measured at an amount other than cost, are measured at the amounts specified in the relevant accounting standards. The residual transaction price is then allocated to the remaining identifiable assets and liabilities based on their relative fair values at the date of the acquisition. Details of acquisitions in the year meeting this definition can be found in note 16. 3. Financial risk management (a) Financial risk factors The Group’s activities expose it to a variety of financial risks: liquidity risk; market risk (interest rate and foreign currency risk); credit risk and inflation risk. The Group’s treasury function seeks to ensure that sufficient funding is available to meet foreseeable needs and to maintain reasonable headroom for contingencies and manages inflation and interest rate risk. The principal financial risks faced by the Group relate to liquidity, interest rate and credit counterparty risk. These risks and treasury operations are managed by the Group Chief Financial Officer in accordance with policies established by the Board. Major transactions are individually approved by the Board. Treasury activities are reported to the Board and are subject to review by internal audit. Financial instruments are used to raise finance, manage risk, optimise the use of surplus funds and manage overall interest rate performance. The Group does not engage in speculative activity. i) Liquidity risk The Group actively maintains a mixture of long-term and short-term committed facilities which are designed to ensure the Group has sufficient available funds for operations and planned expansions equivalent to at least one year’s forecast requirements at all times. Details of undrawn committed facilities and short-term facilities are provided in note 28. Refinancing risk is managed under a Group policy that requires that no more than 20% of Group net borrowings should mature in any financial year. The Group and water business have entered into covenants with lenders. While terms vary, these typically provide for limits on gearing (primarily based on the water business’s regulatory capital value and unregulated EBITDA) and interest cover. Existing covenants are not impacted by subsequent changes to accounting standards. 197Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 3.

Of the Group’s net borrowings a proportion is RPI index-linked. The interest rate for index-linked debt is based mainly upon an RPI measure; due to current Ofwat methodology the Group has considered other index linked indices which are also used in determining the amount of revenue from customers of South West Water. The Group uses a combination of fixed rate, index-linked borrowings and fixed rate interest swaps as cash flow hedges of future variable interest payments to achieve this policy. The notional principal amounts of the interest rate swaps are used to determine settlement under those swaps and are not therefore an exposure for the Group. These instruments are analysed in note 23. The Group has no significant interest-bearing assets upon which the net return fluctuates from market risk. Deposit interest receivable is expected to largely fluctuate in line with interest payable on floating rate borrowings. Consequently, the Group’s income and cash generated from operations (note 37) are largely independent of changes in market interest rates. For 2024 if interest rates on variable net borrowings had been on average 1% higher/lower with all other variables held constant, post-tax profit for the year and equity would have increased/decreased by £7.6 million (2023 post tax profit for the year and equity would have increased/decreased by £6.4 million), for the equity sensitivity fair value, with derivative impacts excluded. This provides an indication of the changes which could be expected and can be multiplied to support sensitivity analysis, the expected volatility is within the range of 0%-2%. For 2024 if the indices on index-linked borrowings had been on average 1% higher/lower with all other variables held constant, post-tax profit for the year and equity would have decreased/increased by £5.5 million (2023 post tax profit for the year and equity would have increased/decreased by £3.8 million). This provides an indication of the changes which could be expected and can be multiplied to support sensitivity analysis, the expected volatility is within the range of 0%-2%. Foreign currency risk occurs at transactional and translation level from borrowings and transactions in foreign currencies. These risks are managed through forward contracts, which provide certainty over foreign currency risk. iii) Credit risk Credit counterparty risk arises from cash and cash deposits, derivative financial instruments and exposure to customers, including outstanding receivables. Further information on the credit risk relating to trade and other receivables is given in note 22. Counterparty risk arises from the investment of surplus funds and from the use of derivative financial instruments. The Board has agreed a policy for managing such risk which is controlled through credit limits, counterparty approvals, and rigorous monitoring procedures. The Group has no other significant concentration of credit risk. The Group’s surplus funds are managed by the Group’s treasury function and are usually placed in short-term fixed interest deposits or the overnight money markets. Deposit counterparties must meet Board approved minimum criteria based on their short-term credit ratings and therefore be of good credit quality. 198 Annual Report and Accounts 2024 « Pennon Group plc 3. Financial risk management continued iv) Inflation risk Market inflation has caused inflationary pressures across the Group, the Group has index linked facilities which are predominantly Retail Price Index (RPI) linked. Inflation risk arises if the indexes increase meaning the Group will either be paying or accreting the inflation, this could put pressure on the gearing or interest cover ratios. Inflation risk is mitigated through the index linked nature of our revenues and RCV calculations. (b) Capital risk management The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern in order to provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital structure to minimise the cost of capital. The Group’s policy is to have a minimum of 12 months pre-funding of projected capital expenditure. At 31 March 2024 the Group had cash and facilities, including restricted funds, of £601 million (2023 £420 million), meeting this objective. In order to maintain or adjust the capital structure, the Group seeks to maintain a balance of returns to shareholders through dividends and an appropriate capital structure of debt and equity for each business segment and the Group. The Group monitors capital on the basis of the gearing ratio. This ratio is calculated as net borrowings divided by total capital. Net borrowings are analysed in note 38 and calculated as total borrowings less cash and cash deposits. Total capital is calculated as total shareholders’ equity plus net borrowings. The Group currently manages a net borrowings position of £3,809.2 million (2023 2,965.4 million). The gearing ratios at the balance sheet date were: 2024 2023 £m £m Net borrowings (note 38) 3,809.2 2,965.4 Total equity 1,162.6 1,125.2 Total capital 4,971.8 4,090.6 Gearing ratio 76.6% 72.6% The water segment is also monitored on the basis of the ratio of its net borrowings to regulatory capital value. Ofwat’s notional gearing target for the K7 (2020-25) regulatory period is set at 60%. The table below reflects South West Water Limited’s group of companies. The water segment also now includes SES Water, ultimately the ratio of net borrowings to Regulatory Capital Value for the water segment will include SES Water, however this is excluded for the current financial year to aid comparison. South West Water 2024 2023 £m £m Shadow Regulatory Capital Value 5,186.4 4,715.9 Net borrowings 3,294.7 2,865.3 Net borrowings/Regulatory Capital Value 63.5% 60.8% The Group has entered into covenants with lenders and, while terms vary, these typically provide for limits on gearing and interest cover. The Group has been in compliance with its covenants during the year. (c) Determination of fair values The Group uses the following hierarchy for determining the fair value of financial instruments by valuation technique: • Quoted prices (unadjusted) in active markets for identical assets or liabilities (level 1) • Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices) (level 2) • Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs) (level 3). The Group’s financial instruments are valued principally using level 2 measures as analysed in note 23. The fair value of financial instruments not traded in an active market (for example over-the-counter derivatives) is determined by using valuation techniques. A variety of methods and assumptions are used based on market conditions existing at each balance sheet date. Quoted market prices or dealer quotes for similar instruments are used for long-term debt. Other techniques, such as estimated discounted cash flows, are used to determine fair value for the remaining financial instruments. The fair value of interest rate swaps is calculated as the present value of the estimated future cash flows. The carrying values, less expected credit losses, of trade receivables and payables are assumed to approximate to their fair values. 199Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 4. Cri tical accounting judgements and estimates The Group’s principal accounting policies are set out in note 2. Management is required to exercise significant judgement and make use of estimates and assumptions in the application of these policies. Estimates are based on factors including historical experience and expectations of future events that management believe to be reasonable. However, given the judgemental nature of such estimates, actual results could be different from the assumptions used. Estimates Provision for doubtful debts The Group has a material level of exposure to collection of trade receivables. Provisions in respect of these balances are calculated with reference to historical credit loss experience, adjusted for forward- looking factors which by their nature are subject to uncertainty. Analysis of actual recovery compared with provisioning levels have not, to date, resulted in material variances. Under its regular review procedures at the balance sheet date, the Group applies a simplified approach in calculating ECLs for trade receivables and contract assets. Therefore, the Group does not track changes in credit risk but instead recognises a loss allowance based on lifetime ECLs at each reporting date. Each subsidiary has established a provision matrix that is informed by its historical credit loss experience, adjusted for forward-looking factors specific to the receivables and the economic environment. The Group's policy is to write-off trade receivables where the expectation of recovery is considered highly unlikely. The actual level of debt collected may differ from the estimated levels of recovery. As at 31 March 2024 the Group’s current trade receivables were £375.3 million (2023 £280.3 million), against which £125.3 million (2023 £106.5 million) had been provided for ECLs (note 22). Whilst the provisions are considered to be appropriate, changes in estimation basis or in economic conditions could lead to a change in the level of provisions recorded and consequently the charge or credit to the Income Statement. In determining the allowance for ECLs a provisioning matrix is applied to the debt of customers in Devon, Cornwall and Bournemouth, as set out in note 22. An increase/decrease in the provision rates for current occupiers of 1% would lead to an increase/decrease in the level of provision by £1.4 million. Retirement benefit obligations The Group operates defined benefit pension schemes for which actuarial valuations are carried out as determined by the trustees at intervals of not more than three years. The most recent triennial valuation of the main scheme was as at 31 March 2022, the outcome of which is summarised in note 30. The pension cost and liabilities under IAS 19 are assessed in accordance with Directors’ best estimates using the advice of an independent qualified actuary and assumptions in the latest actuarial valuation. The assumptions are based on member data supplied to the actuary and market observations for interest rates and inflation, supplemented by discussions between the actuary and management. The mortality assumption uses a scheme-specific calculation based on CMI 2022 actuarial tables with an allowance for future longevity improvement. The principal assumptions used to measure schemes’ liabilities, sensitivities to changes in those assumptions and future funding obligations are set out in note 30. Judgements Non-underlying items In establishing which items are disclosed separately as non-underlying, to enable a full understanding of the Group’s financial performance, the Directors exercise their judgement in assessing the size, nature or incidence of specific items. See note 6 for further details. Goodwill allocation Goodwill arising on the acquisition of Surrey and East Sutton Water is allocated to the group of cash-generating units that are expected to benefit from the synergies of the combination, the ‘Water CGU’. The Water CGU comprises the regions of South West Water, Bournemouth Water, Bristol Water and Surrey and East Sutton Water. The Water CGU, excluding SES, operates under one management structure with functional integration across the operating segment generating the synergies of the combination. SES continues to operate under separate management whilst Pennon operates under the CMA’s Initial Enforcement Order (IEO). The expected synergies from the acquisition can only begin to be recognised once merger clearance is granted by the CMA. The recoverable amount is the higher of fair value, less costs to sell, and value-in-use. Value-in-use represents the present value of projected future cash flows expected to be derived from a CGU, discounted using a pre-tax discount rate which reflects an assessment of the market cost of capital of the CGU. Impairments are charged to the income statement in the year in which they arise. Other estimates Revenue recognition Management assessed and resolved that the level of estimation for revenue recognition of accrued revenue relating to water and wastewater should not be considered critical as the estimates are largely calculated on a systematic basis and have not, to date, resulted in a material adjustment within the following 12-month period. However, management consider the total level of estimation of accrued revenue relating to water and wastewater to be material and highlight this as a material other estimate. Acquisition accounting The acquisition of SES Water in January 2024 has been accounted for using the acquisition method under IFRS 3. The identifiable assets, liabilities and contingent liabilities are recognised at their fair value at date of acquisition. The fair value of the net assets identified were determined with assistance from independent experts using professional valuation techniques appropriate to the individual category of asset or liability. Calculating the fair values of net assets, notably the fair values of property, plant and equipment given the nature of the infrastructure assets acquired, involves estimation and consequently the fair value exercise is recorded as an other accounting estimate. The depreciation charge is sensitive to the value of property, plant and equipment, a higher or lower fair value calculation would lead to a change in the depreciation charge in the period following acquisition. Capitalisation and determination of useful economic lives of property, plant and equipment The property, plant and equipment of the Group relates primarily to infrastructure assets (being water mains and sewers, impounding and pumped raw water storage reservoirs, dams, pipelines and sea outfalls) as well as other assets which include fixed plant and operational properties. Given the nature of these assets, the Group incurs expenditure including both asset enhancement as well as repairs and maintenance, which involves judgement in allocation of costs between operating and capital expenditure. The Group continues to apply a consistent policy and approach on capitalisation of property, plant and equipment. The useful economic lives of these types of asset vary from 10 to 200 years. Asset lives are reviewed annually and amended where changes are made to assumptions relating to the expected life of the asset from judgement around usage and performance experience, technological advancement and other relevant factors. Overall assessments on the impact of climate change on long life assets have been completed and will be continuously updated for the latest available information. The most recent assessment of the impact on climate change, which includes the potential to mitigate adverse impacts, has not identified any specific impact on the useful economic lives of long life assets. Environmental factors and climate change form part of the planning process for new capital expenditure, where the Group continues apply a consistent policy on capitalisation. The depreciation charge is sensitive to amendments of the useful economic lives of these assets, a significant change in the estimated life of these assets could have a material impact on depreciation, this is therefore noted as a material other estimate. 200 Annual Report and Accounts 2024 « Pennon Group plc 5.

In September 2020, the Group offered its WaterShare+ scheme to its customers whereby customers could choose to accept a credit on their bill or take shares in Pennon Group plc. The scheme operated again in the year ended 31 March 2023. The value of the rebate equated to £13 per customer and the total value of £20.2 million was recognised in full as a non-underlying reduction to revenue in the year ended 31 March 2023. £19.9 million of the WaterShare+ credits were taken as credits on customers’ bills, with the balance of £0.3 million being taken as shares in Pennon Group Plc. This item was non-underlying in nature given its individual size and its non-recurring nature. Additional costs of £2.2 million were incurred in relation to the offering. 2. 2022 was one of the driest and hottest years on record. Elevated demand on the South West Water region from increased tourism and the hot, dry weather led to an approximate 15% increase in distribution input in the year against the expected level from 2017 included in the drought plan. The combination of these individually extreme factors led to extremely low water storage levels in the Colliford Water Resource Zone, with the main supply of Colliford reservoir falling to around 14% capacity in October. A drought was declared by the Environment Agency in Devon and Cornwall in August 2022. In order to react to the drought and water shortage, South West Water invoked a series of emergency measures and one-off expenditure to ensure the region could be supplied with water over the summer and continuing into 2023. Due to the exceptional combination of these events and the significance of the emergency actions, certain costs have been classified as non-underlying given their size, nature and non-recurring incidence. The costs directly addressing these exceptional circumstances include charges for drought permits, water tankering and other water saving measures. In November 2022, South West Water asked households in Cornwall to reduce water usage as part of the ‘Stop The Drop’ campaign to increase reservoir levels. Household customers were offered a £30 bill credit if Colliford reservoir reached 30% storage capacity by 31 December 2022 from a low of around 14%. In December 2022 the company announced the water level in Colliford reservoir reached 30% and as a result all household customers in Cornwall received a £30 credit on their bill. This one-off incentive was provided as part of the response to the drought conditions in the Cornwall area in order to further prompt customers to reduce water usage. The total value of the bill credits amounted to £7.6 million. 3. £13.9 million of costs were incurred in connection with the setting up of a business transformation programme in South West Water following the merger of Bristol Water into South West Water, £0.7 million of which were employment costs. These implementation costs are one-off in nature and incidence, with the benefits from incurring these costs expected to endure into the future on a recurring basis. The programme is still ongoing with further costs of c.£8 million are expected to be incurred in the year ending 31 March 2025. 4. The Group incurred expenses of £9.6 million in the year in connection with the acquisition of SES Water Group and the related investigation by the Competition and Markets Authority (CMA). Due to the one-off nature and incidence of the costs they have been classified as non-underlying. 5. Expenses in connection with the strategic review of renewal energy generating investments, not directly attributable to the intangible assets acquired, totalled £0.6 million. Due to the one-off nature and incidence of the costs they have been classified as non-underlying. 6. The Group incurred expenses of £4.3 million in the year ended 31 March 2023. These related to the integration and statutory transfer of Bristol Water into South West Water. These costs are classified as non-underlying due to their non-recurring nature. 7. On 17 October 2022 Bristol Water plc gave notice of redemption of the £40 million bonds due to be repaid in March 2041. The bonds were redeemed as part of the statutory transfer of the business of Bristol Water to South West Water. The Group carrying value of the bonds at redemption was £91.3 million. The bonds were redeemed on 17 November 2022 for £72.3 million, and the difference arising on early settlement was credited to finance costs in the prior year. Associated legal costs of c.£1 million were also incurred in relation to the bond redemption. The redemption of the bonds is non-recurring and of a material value, hence the credit has been treated as non-underlying. 8. The net tax credit arising on non-underlying items, relates to a deferred tax credit in respect of tax losses carried forward, generated by business transformation costs. The prior year credit reflected a £2.8 million current tax credit in respect of losses carried back against prior year profits. The prior year also included a deferred tax credit of £1.9 million relating to tax losses carried forwards and the deferred tax unwind of the fair value adjustment in relation to the Bristol Water bond terminated in the prior year. 9. Following the Chancellor's Budget on 4 March 2021 and subsequent substantial enactment of the Finance Act on 24 May 2021, the UK's main rate of corporation tax increased to 25% from 1 April 2023. All deferred tax assets and liabilities were therefore reviewed and where they will crystallise after 1 April 2023 were recalculated to crystallise at 25%. This charge is considered non-underlying due to it arising from a material legislative change and its treatment is consistent with that applied in relation to previous changes in corporation tax rates. A £0.6 million deferred tax credit in respect of rate change arose in the year ended 31 March 2023, in respect of tax losses carried forwards which will be relieved at 25%. 203Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 7.

UK corporation tax for the Group is stated after a credit relating to prior year current tax of £0.6 million (2023 £2.7 million credit) and a prior year deferred tax charge of £nil (2023 £1.0 million charge). These items relate to prior year adjustments in respect of additional interest deductions due in accordance with UK tax legislation. The tax for the year differs from the theoretical amount which would arise using the standard rate of corporation tax in the UK of 25% (2023 19%) as follows: 2024 2023 £m £m Reconciliation of total tax credit Loss before tax (9.1) (8.5) Loss multiplied by the standard rate of UK corporation tax of 25% (2023 19%) (2.3) (1.6) Effects of: E xpenses/(income) not deductible for tax purposes 1.6 (0.4) Joint venture profits not taxable (0.2) (0.1) Adjustments to tax charge in respect of prior years (0.6) (1.7) Change in UK tax rates – (1.0) Depreciation charged on non-qualifying assets 0.9 0.7 Other – (4.8) Tax credit for year (0.6) (8.9) 2024 2023 £m £m Reconciliation of current tax credit Loss before tax (9.1) (8.5) Loss multiplied by the standard rate of UK corporation tax of 25% (2023 19%) (2.3) (1.6) Effects of: Relie f for capital allowances in place of depreciation (37.0) (37.6) Disallowance of depreciation charged in the accounts 36.5 24.4 Other timing differences (5.3) (11.1) Expenses/(income) not deductible for tax purposes 1.6 (0.4) Joint venture profits not taxable (0.2) (0.1) Accounting policy alignment adjustment on acquisition of Bristol Water – 5.0 Adjustments to tax charge in respect of prior years (0.6) (2.7) Depreciation charged on non-qualifying assets 0.9 0.7 Tax losses carried forward 9.3 18.6 Relief for capitalised interest and foreign exchange gains/losses (3.5) (0.7) Current tax credit for year (0.6) (5.5) The Group's current tax credit is lower than the UK headline rate of 25%, primarily due to losses generated which are carried forward to offset against future taxable profit. The Group benefits from the 100% full expensing and 50% enhanced allowances in respect of qualifying spend relating to certain qualifying assets (largely plant and machinery). The Group incurs significant capital expenditure each year as it maintains and enhances it assets for the benefit of its customers, communities and the environment. These enhanced allowances have increased capital allowance claims for the year and contributed significantly to the current tax credit for the year. There is also a consequently higher deferred tax liability and charge due to the additional capital allowance deductions. 205Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 9. Tax ation continued Certain types of expenditure are not deductible for tax purposes. These types of expenditure are set out in tax legislation. The main category of expenditure not deductible during the year are acquisition costs relating to the purchase of the SES Group and various renewables businesses, where these are classified as capital in nature for tax purposes. Profits from joint ventures are included in the consolidated accounts on an after tax basis, as such these profits are not taxable in the Group accounts. The accounting policy alignment relates to Bristol Water plc aligning their accounting policy in relation to deferred income to that of South West Water on acquisition. Despite the accounting adjustments reflecting these the restated 2022 figures, for tax purposes the adjustment was subject to corporation tax during the year ended 31 March 2023. This was a one-off item in that year. Adjustments to the tax charge in respect of prior year arise from the return to provision adjustments booked, having completed and submitted the corporation tax returns for the year ended 31 March 2023 in March 2024, as well as submitting an amended return for the year ended 31 March 2021 as a result of the closure of Viridor enquiries, which have a subsequent affect on the Group. These are routine items with any adjustments reflected in the current year’s tax charge. Depreciation charge on non-qualifying assets generates a permanent adjustment which increases the tax charge. Non-qualifying assets are those which do not qualify for writing down tax allowances including certain fixed assets typically in relation to older buildings and premises where tax relief is not available. Tax losses generated in the year and carried forward generate a deferred tax rather than current tax credit, hence the adjustment to current tax. When utilised, the adjustment will be reflected through a movement from deferred to current tax. Other timing differences relate to the timing of relief for items including pensions, general provisions and financial derivatives. The reduction in the year relates mainly to additional pension contributions made to fund deficits in the scheme. Immediate tax relief is available in respect of capitalised interest and foreign exchange gains/losses. In addition to the amounts recognised in the income statement, the following tax charges/(credits) (which include the effect of the change in tax rate) were recognised: 2024 2023 £m £m Amounts recognised directly in other comprehensive income Deferred tax credit on defined benefit pension schemes (2.2) (9.8) Deferred tax (credit)/charge on cash flow hedges (4.1) 7.3 Amounts recognised directly in equity Deferred tax charge on share-based payments 0.1 0.5 Factors affecting future tax charges The Chancellor announced in the November 2023 Autumn statement that full expensing on qualifying plant and machinery has been made permanent. This applies to plant and machinery with an expected life of less than 25 years. The 50% first year allowance on long life plant and machinery has also been made permanent. Pillar Two legislation has been enacted in the UK which is the only jurisdiction in which the Group operates. The legislation will be effective for the Group’s financial year beginning 1 April 2024. The Group has performed an assessment of the Group’s potential exposure to Pillar two income taxes. This assessment is based on the most recent financial information available regarding the financial performance of the constituent entities in the Group. Based on the assessment performed, the Pillar Two effective tax rates in the only jurisdiction in which the Group operates i.e. the UK, is above 15% and management is not currently aware of any circumstances under which this might change. Therefore, the Group does not expect a potential exposure to Pillar Two top-up taxes. 10. Profit of the parent company 2024 2023 £m £m Profit attributable to ordinary shareholders’ equity dealt within the accounts of the parent company 34.4 8.4 As permitted by Section 408 of the Companies Act 2006, no income statement or statement of comprehensive income is presented for the Company. 11. Earnings per share Basic earnings per share are calculated by dividing the earnings attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the year, excluding those held in the employee share trust (note 36), which are treated as cancelled. For diluted earnings per share, the weighted average number of ordinary shares in issue is adjusted to include all dilutive potential ordinary shares. The Group has two types of dilutive potential ordinary shares – those share options granted to employees where the exercise price is less than the average market price of the Company’s ordinary shares during the year; and the contingently issuable shares under the Group’s Performance and Co-investment Plan, the long-term incentive plan and the deferred shares element of the Annual Incentive Bonus Plan, based on performance criteria for the vesting of the awards. Potential ordinary shares, as discussed above, that could dilute basic earnings per share in the future, were not included in the calculation for statutory earnings per share because they were anti-dilutive for the current year. The weighted average number of shares and earnings used in the calculations are detailed in the table below. 2024 2023 Number of shares (millions) For basic earnings per share 266.6 261.9 Effect of dilutive potential ordinary shares from share options – 0.9 For diluted earnings per share 266.6 262.8 206 Annual Report and Accounts 2024 « Pennon Group plc 11. Earnings per share continued Basic and diluted earnings per ordinary share Earnings per ordinary share before non-underlying items and deferred tax are presented as the Directors believe that this measure provides a more useful year on year comparison of business trends and performance. Deferred tax is excluded as the Directors believe it reflects a distortive effect of changes in corporation tax rates and the level of long-term capital investment.

Goodwill £m Cost: At 1 April 2022 163.9 At 31 March 2023 163.9 Acquisition of SES Water Group (note 43) 15.6 At 31 March 2024 179.5 Carrying amount: At 1 April 2022 163.9 At 31 March 2023 163.9 At 31 March 2024 179.5 Goodwill acquired in a business combination is allocated at acquisition to the CGU expected to benefit from that business combination. During the year ended 31 March 2024, the Group acquired the SES Water Group, adding £15.6 million to goodwill (see note 43). All goodwill represents the water business, therefore this is the lowest level at which goodwill is monitored and tested. Impairment testing of goodwill The Group tests goodwill for impairment annually, or more frequently if there are any indications that impairment may have arisen. The recoverable amount of the water business segment is assessed using level 2 fair value hierarchy techniques, with reference to the market value of the water business, using a market-based observable premium, based on historical water industry merger and acquisition activity, to regulated capital value as defined by Ofwat. The results of tests performed during the year demonstrate significant headroom in the water CGU, and it is judged that no reasonable change in the key assumptions would cause the carrying amount of the CGUs to exceed the recoverable amount. 208 Annual Report and Accounts 2024 « Pennon Group plc 16.

On 10 January 2024 the Company acquired 100% of the issued share capital of Sumisho Osaka Gas Water UK Limited, which has subsequently been renamed Sutton and East Surrey Group Holdings Limited (‘SESGHL’). SESGHL is the holding company of the SESGHL Group which comprises Sutton and East Surrey Water plc (‘SES Water’), a regulated water only company, and certain other ancillary businesses. On 1 February 2024, the Company subscribed for 25,000 new ordinary shares in its wholly-owned subsidiary undertaking, Pennon Power Limited, for consideration of £25,000,000. On 28 March 2024, the Company subscribed for 10,000,000 new ordinary shares in Sutton and East Surrey Group Holdings Limited, for consideration of £5,000,000. During the year, the Company received a dividend of £283.6 million from its subsidiary, Viridor Waste 2 Limited, reducing that entity’s net assets to £nil. Accordingly, the Company impaired its investment in Viridor Waste 2 Limited. During the prior year, as part of the statutory licence transfer of Bristol Water to South West Water, the Company transferred its shareholding in Bristol Water plc to South West Water Limited for £413 million. The consideration was satisfied through the Company subscribing for an additional £1 of share capital of South West Water Limited at a premium of £413 million. 213Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 20.

Trade receivables have increased year on year, due to the acquisition of Sutton and East Surrey Water, and the effect in the prior year of one-off bill reductions in the final quarter in relation to Watershare+ and the drought incentive along with tariff increases in the South West Water region. Accrued income includes £28.3 million (2023 £25.7 million) in respect of metered accrual revenue in the retail water business. Metered accrual revenue relates to performance obligations that have been fully extinguished in providing services to customers prior to the reporting date. Payment in respect of these services is a matter of time following issuance of invoices. The Directors consider that the carrying amounts of trade and other receivables approximate to their fair value. There is no concentration of credit risk in trade receivables. The Group has a large number of customers who are dispersed and there is no significant loss on trade receivables expected that has not been provided for. The Group applies the simplified approach in calculating the expected credit losses for trade receivables allowing a provision matrix to be used which is based on the expected life of trade receivables, default rates for different customer categories within the collection process and forward-looking information. As at 31 March, an analysis of the ageing of trade receivables is as follows: 2024 2023 £m £m Group Not due 40.9 57.5 Past due 1 – 30 days 45.7 14.7 Past due 31 – 120 days 29.5 17.1 More than 120 days 259.2 191.0 375.3 280.3 The aged trade receivables above are taken directly from aged sales ledger records. The Group’s operating businesses specifically review separate categories of debt to identify an appropriate allowance for expected credit losses as outlined in note 2 (n) ii). South West Water Limited and SES Water have a duty under legislation to continue to provide domestic customers with services regardless of payment. Given the different nature of customer demographics within South West Water’s operating area, SES Water’s operating area and the non-household retail business of Pennon Water Services and SESWS, different provision matrices are adopted by each business. The provision matrix adopted for household customers in the most significant operating region of Devon, Cornwall & Bournemouth is outlined in the table below, showing the range of provision rates dependent on phase of collection. The table also includes the gross debt and provision rates for other customer areas: Trade receivables 2024 £m A A l l l l o o w w a a n n c c e e f f o o r r e e x x p p e e c c t t e e d d c c r r e e d d i i t t l l o o s s s s e e s s 2024 £m Trade receivables 2023 £m Allowance for expected credit losses 2023 £m Devon, Cornwall & Bournemouth (household customers) • Current occupier < 12 months: 1% - 30% 44.8 0.2 35.3 0.2 • Current occupier 12 – 24 months: 10% – 60% 23.1 3.2 14.6 2.8 • Current occupier 24 – 36 months: 15% – 80% 11.5 2.8 10.8 3.4 • Current occupier > 36 months: 20% – 100% 89.2 48.2 90.4 49.5 • Previous occupier: 55% – 100% 53.3 31.3 51.9 31.3 Bristol 37.8 8.6 31.0 5.4 SES 53.3 16.7 – – Pennon Water Services (Non-household retail) 40.6 14.3 38.3 13.5 Other 21.7 – 8.0 0.4 375.3 125.3 280.3 106.5 215Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 22.

The fair value of derivatives is split between current and non-current assets or liabilities based on the maturity of the cash flows. The ineffective portion recognised in the income statement arising from hedging relationships was £nil (2023 £nil). A net £16.4 million debit (2023 £29.1 million credit) was recognised in other comprehensive income for cash flow hedges, including a £0.2 million credit (2023: £nil) recognised in profit and loss relating to cash flow hedges previously recognised through other comprehensive income and recorded in the hedging reserve. Interest rate swaps, primarily cash flow hedges, and fixed rate borrowings are used to manage the mix of fixed and floating rates to ensure at least 60% of Group net borrowings are at fixed rate. At 31 March 2024 the Group had interest rate swaps to swap from floating to fixed rate and hedged financial liabilities with a notional value of £939.0 million and a weighted average maturity of 3.5 years (2023 £853 million, with 3.4 years). The weighted average interest rate of the swaps for their nominal amount was 1.85% (2023 1.54%). The Group had cross currency swaps and hedged financial liabilities with a notional value of £64 million and a weighted average maturity of 4.5 years. The weighted average exchange rate of the swaps for their nominal amount was 0.80. The Group has established a hedge ratio of 1:1 for the hedging relationships as the underlying risks of the swaps are identical to the hedged risk components. To test the hedge effectiveness, the Group uses the hypothetical derivative method and compares the changes in the fair value of the hedging instrument against the changes in fair value of the hedged item attributable to the hedged risk. The hedge ineffectiveness can arise from: • Different interest rate curve applied to discount the hedged item and hedging instrument • Differences in timing of cash flows of the hedged item and hedging instrument • The counterparties’ credit risk differently impacting the fair value movements of the hedging instrument and hedged item The impact of the hedging instrument on the statement of financial position is as follows: G G r r o o u u p p Notional amount £m Carrying amount £m Line item in the statement of financial position Change in fair value used for measuring ineffectiveness in the period £m A A s s a a t t 3 3 1 1 M M a a r r c c h h 2 2 0 0 2 2 4 4 Interest rate swaps 939.4 38.0 Derivative financial instruments (14.4) RPI swaps 300.0 (4.6) Derivative financial instruments (0.2) Cross currency swaps 64.1 (1.3) Derivative financial instruments (2.4) As at 31 March 2023 Interest rate swaps 853.4 52.4 Derivative financial instruments 33.6 RPI swaps 300.0 (4.4) Derivative financial instruments (4.4) Cross currency swaps 24.0 1.1 Derivative financial instruments (0.5) C C o o m m p p a a n n y y Notional amount £m Carrying amount £m Line item in the statement of financial position Change in fair value used for measuring ineffectiveness in the period £m A A s s a a t t 3 3 1 1 M M a a r r c c h h 2 2 0 0 2 2 4 4 Cross currency swaps 24.0 0.8 Derivative financial instruments (0.3) As at 31 March 2023 Cross currency swaps 24.0 1.1 Derivative financial instruments (0.5) 216 Annual Report and Accounts 2024 « Pennon Group plc 23.

The fair value of financial instruments not traded in an active market (level 2, for example over-the-counter derivatives) is determined by using valuation techniques. A variety of methods and assumptions are used based on market conditions existing at each balance sheet date. Quoted market prices or dealer quotes for similar instruments are used for long-term debt. Other techniques, such as estimated discounted cash flows, are used to determine fair value for the remaining financial instruments.

The hedging relationship was de-designated in previous periods at which point the fair value amount recognised at that point ceased to be revalued. The fixed financial liability at the point of de-designation is released to the income statement over the remaining life of the debt. 217Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 25.

As at 31 March 2024 the carrying value of leases previously categorised as IAS 17 operating leases was £36.4 million (2023 £37.3 million). The Group does not face a significant liquidity risk with regard to its lease liabilities. Lease liabilities are monitored within the Group’s treasury function. The discount rate used to calculate the lease liabilities above involves estimation. Where the Group cannot readily determine the rate implicit in the lease the Group uses an estimated incremental borrowing rate (IBR). At 31 March 2024 the range of IBRs used was between 6.1% and 6.8% (2023 between 2.6% and 3.9%) and the weighted average IBR across all leases was 6.3% (2023 3.3%). If the weighted average rate used increased or decreased by 10bps, this would result in a c.1.0% increase or reduction in the present value of lease liabilities recognised at 31 March 2024 (2023 c.1.1%). The period for repayment of certain leases includes an agreement to deposit with the lessor group amounts equal to the difference between the original and revised payments due. The accumulated deposits, £25.9 million at 31 March 2024 (2023 £21.6 million), are currently being held to settle the lease liability subject to rights to release by negotiation with the lessor. The deposits are subject to a registered charge given as security to the lessor for the balance outstanding. Cash outflows in respect of leasing relate to principal repayments of £19.0 million (2023 £120.3 million) and interest repayments of £53.1 million (2023 £100.5 million), in addition to inflows from lease financing arrangements of £64.8 million (2023 £40.2 million).

The majority of the contract liabilities included above are expected to unwind after five years. 30. Retirement benefit obligations During the year the Group operated a number of defined benefit pension schemes and also defined contribution schemes. The principal plan within the Group is the Pennon Group Pension Scheme (PGPS), which is a funded defined benefit, final salary pension scheme in the UK. Following the acquisition of Bristol Water and SES, the Group also assumed defined benefit obligations through Bristol Water’s and SES’s membership of Water Companies Pension Scheme (‘WCPS’). The Group’s pension schemes are established under trust law and comply with all relevant UK legislation. The assets of the Group’s pension schemes are held in separate trustee administered funds. The trustees of the funds are required to act in the best interest of the funds’ beneficiaries. The appointment of schemes’ trustees is determined by the schemes’ trust documentation. The Group has a policy for the PGPS that one-half of all trustees, other than the Chair, are nominated by members of the schemes, including pensioners. Bristol Water’s membership of WCPS is through a separate section of that scheme. The assets of the section are held separately from those of the Group and are invested by discretionary fund managers appointed by the trustees of the scheme. The employees in the section ceased to earn additional defined benefit pensions on 31 March 2016. There were no employer contributions to the scheme from that date and from 30 June 2016, with the agreement of the trustees, deficit contributions also ceased. All eligible employees were offered membership of a stakeholder pension scheme. In 2018 the trustees of the Bristol Water section of the WCPS purchased a bulk annuity policy to insure the benefits for members of the section. Following this the method for valuing the liabilities of the pension scheme has remained the same. However, the scheme assets, in the form of the insurance policy, now materially match the value of the liabilities. The process to buy up and wind up the scheme is continuing, including discussions regarding the release of the surplus on completion of this process. 221Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 30. Retirement benefit obligations continued SES’s membership of WCPS is through a separate section of that scheme. The assets of the section are held separately from those of the Group and are invested by discretionary fund managers appointed by the trustees of the scheme. The employees in the section ceased to earn additional defined benefit pensions on 31 March 2019. With effect from 31 March 2023 the trustees of the SES section of the WCPS purchased a bulk annuity policy to insure the benefits for members of the section. Following this the method for valuing the liabilities of the pension scheme has remained the same. However, the scheme assets, in the form of the insurance policy, now materially match the value of the liabilities. PGPS is closed to future accrual. In June 2023, the High Court handed down a decision (Virgin Media Limited v NTL Pension Trustees II Limited and others) which potentially has implications for the validity of amendments made by schemes, including the PGPS and other Group defined benefit schemes, which were contracted- out on a salary-related basis between 6 April 1997 and the abolition of contracting-out in 2016. This decision has been appealed and is due to be reconsidered by the Court of Appeal in June 2024. The impact will therefore be uncertain for some time to come. Given this uncertainty, the updated valuation as at 31 March 2024 does not reflect the High Court ruling as it is currently unclear as to whether any additional liabilities might arise, and if they were to arise, how they would be reliably measured. The case is subject to appeal in 2024 and following the outcome of the appeal and any DWP response, management will conclude whether any subsequent actions or amendments to IAS 19 liabilities are required. Defined contribution schemes Pension costs for defined contribution schemes were £12.0 million (2023 £9.4 million). Defined benefit schemes Assumptions The principal actuarial assumptions at 31 March were: 2024 2023 % % Rate of increase in pensionable pay 2.6 2.7 Rate of increase for current and future pensions 2.8 2.8 Rate used to discount schemes’ liabilities and expected return on schemes’ assets 4.8 4.7 Inflation 3.2 3.3 Mortality Assumptions regarding future mortality experience are set based on actuarial advice in accordance with published statistics and experience. The mortality assumption uses a scheme-specific calculation based on CMI 2022 actuarial tables with an allowance for future longevity improvement. The average life expectancy in years of a member having retired at age 62 on the balance sheet date is projected as: 2024 2023 Male 24.1 24.2 Female 26.8 26.7 The average life expectancy in years of a future pensioner retiring at age 62, 20 years after the balance sheet date, is projected as: 2024 2023 Male 25.5 25.6 Female 28.3 28.2 The sensitivities regarding the principal assumptions used to measure the schemes’ liabilities are: Change in Impact on assumption schemes’ liabilities Rate of increase in current and future pensions +/– 0.5% +/– 4.8% Rate used to discount schemes’ liabilities +/– 0.5% –/+ 6.2% Inflation +/– 0.5% +/– 4.4% Life expectancy +/– 1 year +/– 3.9% The sensitivity analysis shows the effect of changes in the principal assumptions used for the measurement of the pension liability. The method used to calculate the sensitivities is approximate and has been determined taking into account the duration of the liabilities and the overall profile of each scheme’s membership. This is the same approach as has been adopted in previous years.

In respect of the Group’s principal pension scheme, PGPS, the surplus has been recognised as the Group believes that ultimately it has an unconditional right to a refund of any surplus assuming the full settlement of the plan’s liabilities in a single event, such as a scheme wind up. Bristol Water The Group believes that it has an unconditional right to a refund of surplus and that the gross pension surplus can be recognised. This benefit is only available as a refund as no additional defined pension benefits are being earned. Under UK tax legislation a tax deduction of 25% (2023 35%) is applied to a refund from a UK pension scheme, before it is passed to the employer. This tax deduction has been applied to restrict the value of the surplus recognised for this scheme. The effect of the change in the rate of tax in the year of £1.2 million is presented within Experience (losses)/gains. Sutton and East Surrey Water The Group believes that it has an unconditional right to a refund of surplus and that the gross pension surplus can be recognised. This benefit is only available as a refund as no additional defined pension benefits are being earned. Under UK tax legislation a tax deduction of 25% is applied to a refund from a UK pension scheme, before it is passed to the employer.

The schemes hold a proportion of growth assets (equities and diversified growth funds) which are expected to outperform corporate bonds in the long term, but can give rise to volatility and risk in the short term. As the funding of the schemes improves, an increasing proportion of the schemes’ assets are invested in less volatile asset classes such as cash and bonds which more closely reflect market movements in the schemes’ liabilities. The allocation to growth assets is monitored such that it is suitable with the schemes’ long- term objectives. Changes in bond yields A decrease in corporate bond yields will increase the schemes’ liabilities, although this will be partially offset by an increase in the value of the schemes’ bond holdings. Inflation risk The majority of the schemes’ benefit obligations are linked to inflation, and higher inflation will lead to higher liabilities (although, in most cases, caps on the level of inflationary increases are in place to protect against extreme inflation). The scheme uses LDIs (‘Liability Driven Investment Funds’) within the asset portfolios to hedge against the value of liabilities changing as a result of movements in long-term interest rates and inflation expectations. The structure allows the scheme to both hedge against the risks and retain capital investment in assets that are expected to generate higher returns. Whilst LDIs are an integral part of the hedging strategy, risk management and monitoring strategies are in place to ensure that the collateral requirements to maintain these structures are closely managed. Life expectancy The majority of the schemes’ obligations are to provide benefits for the life of the member, so increases in life expectancy will result in an increase in the liabilities. In conjunction with its investment advisers, the trustees have structured the schemes’ investments with the objective of balancing investment returns and levels of risk. The asset allocation for the main scheme has three principal elements: • Holding of cash funds and bonds which are expected to be less volatile than most other asset classes and reflects market movements in the schemes’ liabilities • A proportion of equities with fund managers having freedom in making investment decisions to maximise returns, and • Investment of a proportion of the schemes’ assets in alternative asset classes which give the potential for diversification (currently property, insurance linked securities and diversified growth). The liabilities of the defined benefit schemes are measured by using the projected unit credit method which is an accrued benefits valuation method in which the scheme liabilities make allowance for projected increases in pensionable pay. 224 Annual Report and Accounts 2024 « Pennon Group plc 30. Retirement benefit obligations continued As funding of our principal pension scheme has improved the investment portfolio has been de-risked through increasing the scheme’s real gilts hedging position through LDIs (Liability Driven Investments), which are commonly used by UK pension schemes. The weighted average duration of the defined benefit obligation is 12 to 13 years (2023: 12 to 15 years). The 2022 triennial actuarial valuation of the principal defined benefit scheme was agreed in 2024 with an actuarial valuation surplus of £7.6 million. No deficit recovery contributions are required as a result of the 2022 valuation. Additional contributions of £2.0 million were paid into the scheme in respect of scheme expenses (2023: £1.6 million). The Group monitors funding levels on an annual basis and the Group expects to pay only scheme expenses of around £1.8 million, during the year ended 31 March 2025. The last formal actuarial valuation of the Bristol Water section of the WCPS was at 31 March 2017. The last formal valuation of the SES section of the WCPS was at 31 March 2022. 31.

The Group has concluded that it is appropriate to continue not to recognise a deferred tax asset on these temporary differences. While the Group is in a net deferred tax liability position, the Group consider there is not a right to offset these deferred tax assets against deferred tax liabilities. In addition, whilst the assets are available indefinitely, there is uncertainty regarding the availability of suitable future taxable profits.

Capital allowances provide tax relief on these items in place of accounting depreciation which is not tax deductible. Over the period of ownership of an asset, cumulative depreciation and capital allowances will equalise. Capital allowance rates are set by the UK Government and every business receives the same rate of allowance. Capital allowance rates typically vary from 3% up to 100%. Depreciation periods vary from 4 to 200 years. Due to the group's continuing capital investment programme, deductions for capital allowances are expected to exceed depreciation in future years. The different accounting treatment of property, plant and equipment for tax and accounting purposes means that the taxable income of the Group is not the same as the profit reported in the financial statements. The adjustments for this are reflected in the current tax reconciliation. As explained in note 9, the Government has introduced permanent full expensing and 50% first year allowances for certain qualifying expenditure. This provides an increase in current tax relief for the Group with a consequently higher deferred tax liability and charge due to the additional capital allowance deductions. Short term temporary differences arise on items such as retirement benefit obligations, derivatives and share based payments because the treatment of such items are different for tax and accounting purposes. These differences reverse over future years following that in which they arise, as is reflected in the deferred tax charge in these financial statements. Specifically, retirement benefit obligations will crystallise over the life of the pension scheme and/or the period when spreading applies (this can be up to three years for spreading purposes), whilst share based payments will crystallise over the remaining life of the share schemes which are up to 5 years. Short term liabilities including provisions will typically crystallise in the following year. The fair value liability relates to the revaluation of tangible fixed assets on the acquisition of Bournemouth Water, Bristol Water and SES Water. The fair value asset relates to the revaluation of debt on the acquisition of Bournemouth Water and Bristol Water. These items will be released over their remaining life which is up to 141 years. Where interest charges or other costs are capitalised in the accounts, tax relief is either given as the charges are incurred or when the costs are taken to the income statement. Derivatives reflect the fair value movements on treasury derivatives, these can fluctuate considerably each year. The balance will crystallise when derivative items are either terminated or mature, the life of these items can be up to ten years. Tax losses relate to trading losses and non-trade deficits carried forwards in relation to the UK's corporate interest restriction rules. These are available indefinitely. With respect to trading losses, these are recognised on the basis the UK Group has taxable temporary differences that are expected to reverse in the same periods as the unused tax losses and there is a right of offset. With respect to the non-trade deficits, current forecasts indicate that these deficits will be utilised over the next 25 to 35 years on the basis the group does not retract any of its existing Public Benefit Exemption elections. 32.

Share capital continued During the year the Group issued 24,657,535 new ordinary shares of 61.05 pence each in connection with the acquisition of SES Water Group (see note 43). The equity capital raise will be used to reduce leverage in the enlarged group following the acquisition. During the year ended 31 March 2023, the Group concluded the Buy-back programme, with the total aggregate cost of the programme being £239.5 million. The Group purchased £39.9 million of ordinary shares from the market at an average ordinary share price of 1,022 pence during the year ended 31 March 2023. The shares acquired under the tender offer were immediately cancelled, creating a capital redemption reserve of £2.4 million. Employee share schemes The Group operates a number of equity-settled share plans for the benefit of employees. Details of each plan are: i) Sharesave Scheme An all-employee savings-related plan is operated that enables employees, including Executive Directors, to invest up to a maximum of £500 per month for three or five years. These savings can then be used to buy ordinary shares, at a price set at a 17% or 20% discount to the market value at the start of the savings period, at the third or fifth year anniversary of the option being granted. Options expire six months following the exercise date and, except for certain specific circumstances such as redundancy, lapse if the employee leaves the Group before the option exercise period commences. Outstanding options to subscribe for ordinary shares of 61.05 pence each under the Company’s share option schemes are: Date granted and Period when Thousands of shares in respect of subscription price options normally which options outstanding at fully paid exercisable 31 March 2024 2023 3 July 2018 635p 2021 – 2023 1 100 9 July 2019 620p 2022 – 2024 69 84 19 July 2020 928p 2023 – 2025 30 193 6 July 2021 879p 2024 – 2026 306 552 5 July 2022 828p 2025 – 2027 302 533 4 July 2023 663p 2026 – 2028 753 – 1,461 1,462 The number and weighted average exercise price of Sharesave options are: 2024 2023 Weighted average Weighted Number of exercise Number of average exercise ordinary shares price per share ordinary shares price per share (thousands) (p) (thousands) (p) At 1 April 1,462 835 1,501 789 Granted 847 663 598 828 Forfeited (617) 828 (215) 781 Exercised (72) 639 (379) 633 Expired (159) 859 (43) 859 At 31 March 1,461 746 1,462 835 The weighted average price of the Company’s shares at the date of exercise of Sharesave options during the year was 689 pence (2023 927 pence). The options outstanding at 31 March 2024 had a weighted average exercise price of 746 pence (2023 835 pence) and a weighted average remaining contractual life of 2.0 years (2023 1.91 years). The number of exercisable Sharesave options at 31 March 2024 was 1,000 (2023 1,000) and the weighted average exercise price of exercisable Sharesave options was 799 pence (2023 620 pence). The aggregate fair value of Sharesave options granted during the year was £0.7 million (2023 £0.7 million), determined using the Black-Scholes valuation model. The significant inputs into the valuation model at the date of issue of the options were: 2024 2023 Weighted average share price (pence) 700 957 Weighted average exercise price (pence) 663 828 Expected volatility 26% 25% Expected life 3.4 years 3.3 years Risk-free rate 4.5% 1.3% Expected dividend yield 6.1% 4.0% Expected volatility was determined by calculating the historical volatility of the Group’s share price over the previous three years and five years periods depending on the life of the scheme. 228 Annual Report and Accounts 2024 « Pennon Group plc 33. Share capital continued ii) Long-term incentive plan (LTIP) Executive Directors and senior management receive an annual grant of conditional shares. Share awards vest subject to the achievement of specific performance conditions measured over a performance period of not less than three years. More details concerning LTIPs, including performance conditions, is shown in the Directors’ remuneration report on pages 148 to 170.

The aggregate fair value of awards granted during the year was £1.8 million (2023 £1.1 million), determined from market value. No option pricing methodology is applied since the vesting of the shares depends on non-market performance vesting conditions. In the prior year, having reflected on the exceptional economic backdrop and in particular the cost-of-living crises faced by many of our customers, the CEO recommended that the Remuneration Committee consider lapsing her bonus and 2020 LTIP awards in full, and diverting an equivalent value into the Group’s Watershare+ scheme. The Watershare+ scheme directly benefits the Group’s customers by either providing money off their bill or via ownership of Pennon Group plc shares. While recognising the performance delivered, the Remuneration Committee accepted and approved the CEO’s recommendation regarding her awards. iii) Annual Incentive Bonus Plan – deferred shares Awards under the plan to Executive Directors and senior management involve the release of ordinary shares in the Company to participants. There is no performance condition since vesting is conditional upon continuous service with the Group for a period of three years from the award.

The Company’s share price at the date of the awards ranged from 700 pence to 1,141 pence (2023 988 pence to 1,141 pence). The aggregate fair value of awards granted during the year was £0.9 million (2023 £0.5 million), determined from market value. No option pricing methodology is applied since dividends paid on the shares are receivable by the participants in the scheme.

Other contractual and litigation uncertainties Ofwat and the Environment Agency announced an industry-wide investigation into sewage treatment works on 18 November 2021. On 27 June 2022, as part of its ongoing investigation, Ofwat announced enforcement action against South West Water Limited, the company is now included alongside the five companies that received enforcement notices in March 2022. The Group continues to work openly with Ofwat to comply with the notice as part of this ongoing investigation. The Group has undertaken its own internal investigation and investment interventions have been undertaken at a small number of our sites. In addition, the Group has looked for opportunities for additional future investment to include further storm storage and an extension of its sewer misuse programme which has been shared with Ofwat. Ofwat have yet to formally respond on the investigation and the timing of a response is unknown, although has been potentially indicated for Summer 2024. Until such time that an initial response is received, the potential outcome of these investigations continues to be unknown. Ofwat has a range of options that it could apply from closing the investigation with no further action, agreeing to formal S.19 undertakings through to fining the Group up to 10% of its revenue in relation to the regulated wastewater business. Given the wide range of possible outcomes therefore the potential outcome of this investigation continues to be unknown, and it is not possible to estimate any obligations arising from the investigation with any certainty. On 23 May 2023 Ofwat announced an investigation into South West Water's 2021/22 operational performance data relating to leakage and per capita consumption. This operational performance data was reported in South West Water's Annual Performance Report 2021/22. This report is subject to assurance processes which include independent checks and balances carried out by an external technical auditor. The Group continues to work openly and constructively with Ofwat to comply with the formal notice issued to South West Water as part of this investigation. The Group has undertaken its own internal investigation into the data and third party experts have concluded the calculations are within a tolerance as reported, as a result there were no detrimental impacts to customers through Outcome Delivery Incentives (‘ODIs’). The Group recognises opportunities to enhance data quality to improve the estimation process and these have been shared with Ofwat. Until such time that an initial response is received, the potential outcome of these investigations continues to be unknown. Ofwat has a range of options that it could apply from closing the investigation with no further action, agreeing to formal S.19 undertakings through to fining the Group up to 10% of its revenue in relation to the regulated drinking water business. Given the wide range of possible outcomes therefore the potential outcome of this investigation continues to be unknown, and it is not possible to estimate any obligations arising from the investigation with any certainty. On 2 February 2024 summons were received by South West Water Limited from the EA in relation to alleged breaches of environmental permits relating to the illegal water discharge activity at 7 locations with a total of 30 charges. The initial court hearing took place on 16 April 2024 at which the company entered no plea, proceedings have been adjourned to 3 July 2024. In May 2024 the EA withdrew 6 of the 30 charges. The potential outcome of the remaining prosecutions is currently unknown. The Group establishes provisions in connection with contracts and litigation where it has a present legal or constructive obligation as a result of past events and where it is more likely than not an outflow of resources will be required to settle the obligation and the amount can be reliably estimated. Where it is uncertain that these conditions are met, a contingent liability is disclosed unless the likelihood of the obligation arising is remote or the matter is not deemed material. 235Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 41.

Acquisition of SES Water Group On 10 January 2024, the Pennon Group acquired 100% of the issued share capital of Sumisho Osaka Gas Water UK Limited, which has subsequently been renamed Sutton and East Surrey Group Holdings Limited (‘SESGHL’). SESGHL is the holding company of the SES Water Group which comprises Sutton and East Surrey Water plc (‘SES Water’), a regulated water only company, and certain other ancillary businesses. The purpose of the acquisition was to expand the Group’s presence in water supply across Southern England. The acquisition of SESGHL is currently under review by the Competition and Markets Authority, and the SESGHL Group has been consolidated into Pennon Group plc’s consolidated financial statements from 10 January 2024 due to management’s assessment of obtaining control of SESGHL as of that date in accordance with IFRS 10. Revenue and profit contribution For the period 9 January 2024 to 31 March 2024, SES Water Group contributed revenue of £35.7 million and loss before tax of £2.7 million to the Group’s result. If the acquisition had occurred on 1 April 2023, management estimates that consolidated revenue would have been £1,031.1 million and consolidated loss for the year would have been £12.4 million. In determining these amounts, management have assumed the fair value adjustments, determined provisionally, that arose on the date of the acquisition would have been the same had the acquisition occurred on 1 April 2023. The details of the business combination are as follows: £m Fair value of consideration transferred Amount settled in cash 90.2 Total consideration transferred 90.2 Fair value of assets and liabilities recognised on acquisition Property, plant and equipment 441.6 Intangible assets 11.6 Inventories 2.1 Trade and other receivables 61.4 Cash and cash deposits 27.5 Current tax receivable 0.4 Borrowings (360.1) Trade and other payables (65.3) Retirement benefit obligations 3.3 Deferred tax liabilities (47.5) Provisions (0.4) Identifiable net assets 74.6 Goodwill on acquisition 15.6 Outflow of cash to acquire subsidiary, net of cash acquired Consideration for equity settled in cash 90.2 Cash and cash equivalents acquired (27.5) Net cash outflow on acquisition 62.7 Acquisition costs paid charged to expenses 9.6 Acquisition related costs Acquisition related costs of £9.6 million are not included as part of the consideration transferred and were recognised as an expense in the consolidated income statement within other operating expenses. 237Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information Notes to the Financial Statements continued 43. Acquisition of SES Water Group continued Adjustments made to the carrying values of SES Water Group at acquisition The net assets recognised in the 31 March 2024 financial statements were based on a provisional assessment of their fair value, whilst all necessary information is finalised to complete the valuation exercise. The initial significant fair value adjustments are described further below and have been incorporated into the 10 January 2024 fair value balance sheet. Acquired receivables The provisional fair value of trade and other receivables acquired as part of the business combination amounted to £32.9 million with a gross contractual amount of £35.1 million. At the acquisition date the Group’s best estimate of the contractual cash flows expected not to be collected amounted to £2.2 million. Goodwill Goodwill is attributable to the recognition of deferred tax liabilities on fair value gains recognised as part of the acquisition. None of the goodwill recognised is expected to be deductible for tax purposes. Goodwill has been allocated to the water segment. The acquisition of the SES Water Group provides a strategic fit for Pennon Group plc as the Group expands its presence in water supply across Southern England. 44. Events after the reporting period On 15 th May 2024 outbreak of cryptosporidium was detected in the water supply in the Brixham area of Devon, causing South West Water to issue a notice to boil water before consuming. All customers issued with a notice to boil water have been offered with compensation of a bank payment or bill credit of £215 per household, the total cost to the Group being c.£3.5 million. 238 Annual Report and Accounts 2024 « Pennon Group plc Alternative performance measures Alternative performance measures (APMs) are financial measures used in this report that are not defined by International Financial Reporting Standards (IFRS). The Directors believe that these APMs assist in providing additional useful information on the underlying trends, performance and position of the Group as well as enhancing the comparability of information between reporting periods. As the Group defines the APMs they might not be directly comparable to other companies’ APMs. They are not intended to be a substitute for, or superior to, IFRS measurements. In 2023/24, the following APMs were added or amended to those presented previously: • The APM for 'Basic adjusted earnings per share (adjusted for share consolidation)' has been discontinued as the impact of the share consolidation is reflected in both the current and prior year.

Returns are made up of a base return (set by Ofwat, the water business regulator, at c.3.9% and c.4.4% for Bristol Water for the period 2020-25) plus totex outperformance, financing outperformance and ODI outperformance. Returns are calculated post tax and post sharing (only a proportion of returns are attributed to shareholders and shown within RORE). The three different types of return calculated and added to the base return are: • Totex outperformance – totex is defined below and outperformance is the difference between actual reported results for the regulated business compared to the Final Determination (Ofwat published document at the start of a regulatory period), in a constant price base • Financing outperformance – is based on the difference between a company’s actual effective interest rate compared with Ofwat’s allowed cost of debt • ODI outperformance – the net reward or penalty a company earns based on a number of different key performance indicators, again set in the Final Determination Regulated equity is a notional proportion of regulated capital value (RCV) which is set by Ofwat at the start of every five-year regulatory period, adjusted foractual inflation. For 2020-25, the notional equity proportion is 40.0%. Further information on this metric can be found in South West Water’s annual performance report and regulatory reporting, published in July each year. Themost recent can be found at: www.southwestwater.co.uk/about-us/how-are-we-performing. Totex Operating costs and capital expenditure of the regulated water and wastewater business (based on the Regulated Accounting Guidelines). Outcome Delivery Incentives (ODIs) ODIs are designed to incentivise companies to deliver improvements to service and outcomes based on customers’ priorities and preferences. If a company exceeds these targets a reward can be earned through future higher revenues. If a company fails to meet them, they can incur a penalty through lower future allowed revenues. Regulatory Capital Value (RCV) RCV has been developed for regulatory purposes and is primarily used in setting price limits. RCV is widely used by the investment community as a proxy for the market value of the regulated business and forms part of covenant debt limits. Shadow RCV reflects the addition of anticipated regulatory adjustments which amend RCV at the end of a regulatory period. These changes are accrued duetoperformance through ODIs, changes in levels of totex expenditure, changes in inflation rates and other regulatory adjustments.

Beware of share fraud The following is taken from the ScamSmart section of the Financial Conduct Authority’s website (www.fca.org.uk/scamsmart). Fraudsters use persuasive and high-pressure tactics to lure investors into scams. They may offer to sell shares that turn out to be worthless ornon-existent, or to buy shares at an inflated price in return for an upfrontpayment. While high profits are promised, if you buy or sell shares in this way you willprobably lose your money. 246 Annual Report and Accounts 2024 « Pennon Group plc How to avoid share fraud Keep in mind that firms authorised by the Financial Conduct Authority (FCA) are unlikely to contact you out of the blue with an offer to buy orsell shares. Do not get into a conversation; note the name of the person and firm contacting you and then end the call. Check the Financial Services Register from http://www.fca.org.uk to see iftheperson and firm contacting you is authorised by the FCA. Beware of fraudsters claiming to be from an authorised firm, copying itswebsite or giving you false contact details. Use the firm’s contact details listed on the Register if you want to call itback. Call the FCA on 0800 111 6768 if the firm does not have contact details onthe Register or you are told they are out of date. Search the FCA Warning List of unauthorised firms at www.fca.org.uk/scamsmart. Consider that if you buy or sell shares from an unauthorised firm you will not have access to the Financial Ombudsman Service or Financial Services Compensation Scheme. Seek impartial advice from a financial adviser before you make an investment. Remember: if it sounds too good to be true, it probably is! 5,000 people contact the Financial Conduct Authority about share fraud each year, with victims losing an average of £20,000. Report a scam If you are approached by fraudsters, please tell the FCA using the share fraudreporting form at http://www.fca.org.uk/scams where you can find out more about investment scams. You can also call the FCA Consumer Helpline on 0800 111 6768. If you have already paid money to share fraudsters you can report this atanytime to Action Fraud using their Online Fraud Report Tool at www.actionfraud.police.uk/reporting-fraud-and-cyber-crime or by calling 0300 123 2040. 247Pennon Group plc » Annual Report and Accounts 2024 Strategic report Governance Financial statements Other information This report is printed on paper certified in accordance with the FSC® (Forest Stewardship Council®) and is recyclable and acid-free.
