Introduction

Letter of the CEO and Chairman

2023 demonstrates that DEME is firmly on track. The year was defined by geographic expansion, new vessels, significant growth, and several wins. We delivered outstanding results, generating a 24% growth in turnover and a 26% increase in EBITDA.

We accomplished so much in 2023, but that's not to say it was easy. Why? Because we push boundaries. Just in 2023 alone, we entered the US offshore wind market and started constructing a wind farm in Taiwan – two new territories for DEME. We introduced revolutionary new vessels -'Viking Neptun' and 'Green Jade' - and new offshore installation concepts, new technologies... We have again dared to be a pioneer while mastering the risks.

Working hard to deliver on our promises

These achievements are only possible due to the remarkable 'One DEME team'. Behind our success is an immense amount of hard work, determination, smart thinking, and ingenuity. Our people are renowned for theirinventive, innovative spirit and their commitment. They work every day to ensure we deliver on our promises to our customers worldwide. We would personally like to thank them for the huge efforts they have made in 2023.

Safety and sustainability are always top priorities. In terms of safety, we continued our strenuous efforts to improve, and we are pleased that our 'Safety Success Stories' are having

such a positive influence. Here, DEME employees and teams share positive experiences and tips forimproving safety.

Sustainability is a consideration in everything we do. We have an ambitious programme in place to reduce greenhouse gas intensity, targeting a 40% reduction by 2030, relative to 2008, per unit of work, and we aim to provide a safe, secure, and healthy working environment for everyone DEME works with. Our care for our employees, and indeed the well-known spirit of our people is reflected in our Energy@DEME sports and wellbeing programme. Our goal is to foster camaraderie and meaningful connections through friendly competition. Beyond personal rewards, our physical activity contributes directly to two very worthy charities - the Belgian cancer charity 'Kom op tegen Kanker' and 'Mercy Ships' globally.

All four segments put in a strong performance

Moving on to ourfour core segments, we are pleased to say that all of them have put in a strong performance. Our strategy ofleveraging the synergies between them with mutual reinforcement is certainly working.

During the year we have witnessed a recalibration in parts of the offshore wind sector following the fact that industry assumptions of a few years ago are no longer valid today. However, we remain fully convinced of the enormous potential that offshore wind offers to achieve the green energy transition. We believe in this industry and always have done - and we are certain of the value that DEME can continue to bring to the industry.

2023 had many wonderful highlights for the Group. For example, the second edition of the North Sea Summit. The event was hosted by the Belgian Prime Minister, and governments from nine countries and 100 CEOs attended, and underlined the ambition to make the North Sea the new green energy hub of Europe. The summit led to the 'The Ostend Declaration' which aims to accelerate the deployment of offshore renewables from the North Sea. We also had the chance to showcase a model of the Princess Elisabeth Island, the first energy island in the world, to the European leaders, including European Commission President Ursula von der Leyen. Princess Elisabeth Island was one of our most exciting wins of the year.

The accelerated push to achieve the energy transition is evidenced in many of our wins during 2023. In our Offshore Energy segment, we installed first steel in the waterin the US. Again, we pioneer. This project has kickstarted a completely new industry in the US market. Southfork Wind is done, Vineyard Wind 1 is well underway and we are now preparing for the Coastal Virginia Offshore Windfarm.

In France, we scored the Le Tréport and Noirmoutier offshore wind farms on the basis of our unique drilling expertise and experience. 'Green Jade', our new floating offshore installation vessel, joined the fleet and started to work on

the Zhong Neng project in Taiwan in July. Other Offshore highlights included a substantial cable contract for Baltic Power, ourfirst offshore wind farm project in Poland. We also continued our activities at the Hinkley Point nuclear power plant in the UK, drilling the shafts for the intake and outfall structures.

In Dredging and Infra, again the pressing need for the energy transition is demonstrated. DEME made history and the year kicked off with the award for Princess Elisabeth Island, which as mentioned earlier, was a particularly special moment. We continued capital dredging works in Abu Qirin Egypt and started dredging and land reclamation works in Abu Dhabi, deploying multiple hopper and cutter dredgers including our'Spartacus'flagship. Furthermore, we have successfully delivered port expansion projects in Sri Lanka, Italy, Poland and we have won new contracts in Africa, India and The Maldives. In the last quarter of the year, we also signed a major contract for the second phase of transformation work for the Port of NEOM, Saudi Arabia, which stands alongside Abu Qirin Egypt as one of the biggest dredging contracts in DEME's history.

Infra has made good progress on the Fehmarnbelt Fixed Link, Oosterweel,

New Lock Terneuzen and the Blankenburg Connection, showcasing our unrivalled immersed tunnel expertise. In the case of the 18-km-long Fehmarnbelt Fixed Link, it will be the longest immersed road and rail tunnel in the world and this mega-tunnel actually crosses a stretch of open sea.

Our Environmental segment successfully progressed with flagship projects in Belgium and in Scotland. Additionally, the team is performing major dyke reinforcement projects that are an important part of the Dutch National Flood Protection Programme. Environmental is also taking the lead in tackling PFAS pollution.

DEME Concessions is forging ahead with the Blankenburg Connection and Port-La Nouvelle and meanwhile, things are progressing well at its 2 GW offshore wind concession, ScotWind. At ourflagship green hydrogen project HYPORT Duqm in Oman, DEME and its development partner OQ signed a Project Development Agreement with Hydrom. HYPORT Duqm remains on track to be

amongst the first in the world to produce green hydrogen and green ammonia.

GSR marked a decade of deep ocean exploration and innovation in 2023, and also saw the entry of Transocean into the company. This powerful strategic alliance will both strengthen GSR's subsea experience and in turn contribute to its leadership position in the deep seabed minerals sector.

Investment programme sees exceptional vessels join the fleet

In 2023, DEME continued its multi-year investment programme with exceptional vessels such as 'Viking Neptun' and 'Green Jade' joining the fleet, and in 2024 another remarkable vessel 'Yellowstone', the largest fallpipe vessel in the world, will become a member of our fleet.

The specialist wind turbine installation vessel 'Sea Installer' underwent a major upgrade that boosted its crane capacity and it successfully installed turbines at Vineyard Offshore Windfarm. This was another milestone moment, being the first offshore wind turbine installation campaign in US history.

The arrival of these new vessels follow strategic choices made many years ago and demonstrate how we anticipate our customers' needs. The new vessels immediately started contributing to our orderbook and turnover and here, we show that we have the right assets for the future. They also help to deliver on our sustainability goals – both 'Viking Neptun' and 'Yellowstone'feature a hybrid power plant. 'Yellowstone' will actually be the first in the fleet to be prepared for(green) methanol.

DEME lives and breathes innovation

DEME works hard to encourage innovation to flourish in our company, forinstance through our disruptive, transformational programme DEMEx. Hundreds of new ideas were suggested by employees looking at how we solve the major global challenges. At the final showcase event in June, we chose the best ideas to be further developed and launched. And certainly, this ability to push boundaries - to dare -is also due to the long-term vision and support of our Board. Endorsed and inspired by the Board, DEME's leadership team is committed to work towards a more sustainable world for the generations to come.

On that note, one of the key members of DEME's Executive Committee, Chief Financial Officer Els Verbraecken, has decided to take the next step in her career and she will leave the company in May 2024. Els joined DEME in 2002 and was appointed CFO in 2013. She has been instrumental in DEME's continued business development, global strategic growth, and our stocklisting. In a seamless handover, we have subsequently appointed homegrown talent Stijn Gaytant, who has been with DEME for more than 20 years, as her successor. On behalf of us, and the Executive

Committee, we would like to thank Els for her dedication and contribution to DEME's success and we wish her the very best in herfuture endeavours.

On track to achieve strategic objectives

DEME has a strong financialfoundation which will allow us to continue our ambitious strategic objectives. We saw a solid growth in our orderbook to a level of 7.6 billion euro and generated 24% growth in turnover and 26% growth in EBITDA. On the strength of these outstanding results, we enter 2024 confident in our ability to deliver on our sustained profitable growth ambition.

Our carefully considered strategy is succeeding. Whether we are carrying out large-scale immersed tunnel projects orintroducing the first monopiles to US waters, the innovation we bring to the industry works. For almost 150 years we have been creating value for our stakeholders and delivering projects in a safe, sustainable, and efficient way. We have the best people, the right assets, technical leadership, the right innovative solutions and crucially, the right spirit!

"We remain fully convinced of the enormous potential that offshore wind offers to achieve the green energy transition. We believe in this industry and always have done."

"The new vessels immediately started contributing to our orderbook and turnover and here, we show that we have the right assets for the future."

Group.

Dredging & Infra held its position as a key EBITDA contributor to the Group, with an 18.6% margin for the year, compared of 16.8% up from last year. Also Environmental delivered a solid increase in EBITDA margin to 16.8% from 12.1% last year, driven in part by an favourable settlement on a completed project. These increases offset the lower performance in Offshore Energy, which recorded a 15.4% margin, compared to 23.2% the previous year, that primarily reflects challenges in the start-up phases of two projects.

The increase in EBITDA yielded an increase in EBIT of 55% compared to 2022, reaching 241 million euro, equivalent to 7.3% of turnover.

In 2023, the Group's net result from joint ventures and associates amounted to a positive 3.2 million euro.

The net profit for the Group for 2023 was 163 million euro up from 113 million euro in 2022.

Operating working capital amounted to -471 million euro as of 31 December 2023 compared to -506 million euro a year ago. Capital expenditure for the year amounted to 399 million euro, a decrease from the 484 million euro invested in 2022, as the company continued its investment programme that was primarily focused on expanding and upgrading the fleet to support future growth.

DEME's financial position remains healthy with a net financial debt of 512 million euro (or 0.9 times EBITDA) compared to 521 million euro (or 1.1 times EBITDA) at the end of 2022.

Outlook

The following statements are forward looking, and actual results may differ materially.

Given the robust demand trends and a strong orderbook, DEME's management remains confident about the company's growth prospects and expects turnover to continue to grow in the coming years with an annual EBITDA margin in a 16% to 20% range each year.

For 2024, taking into account present geopolitical and market conditions, current orderbook and fleet capacity, management expects a turnover growth of at least 10% compared to 2023 with an EBITDA margin comparable to 2023.

Outstanding results "Our 2023, thanks to our capable and dedicated team at DEME, we delivered outstanding results, achieving a 24% growth in turnover and a 26% increase in EBITDA. These figures reflect the effective execution of a variety of projects around the world in all segments while the broader offshore wind market adapted to changing market conditions. In addition, the orderbook reached a robust 7.6 billion euro including sizeable wins across the board, which demonstrate DEME's strong market position and the healthy demand for our capabilities. On the strength of these outstanding results, we enter 2024 confident in our ability to capture the growth opportunities ahead. DEME is strategically well positioned to continue playing a pivotalrole in facilitating the transition to clean energy, addressing environmental challenges and ensuring the reliability and open access of marine trade. We are well equipped to navigate Executive Summary Driven by strong demand across all segments, the orderbook increased 22%, compared to 31 December 2022. This growth is mainly attributed to a series of contract awards in both the Offshore Energy and Dredging & Infra segments, and represents further global expansion. All segments contributed to the Group turnover growth of 24%. In particular, Offshore Energy achieved an outstanding 57% growth in turnover, reflecting the execution of installation projects in Europe, Taiwan and the US, with the latter two regions illustrating the segment's geographical growth strategy. Additionally, Offshore Energy began to reap the benefits of its recently expanded capacity while further incorporating 'Green Jade', a new floating installation vessel and 'Viking Neptun', a cable laying vessel to its fleet in 2023.

Financial figures

Orderbook Turnover (1)

As a group, DEME achieved a historic milestone by surpassing 3 billion euro in turnoverfor the first time. The turnover of theGroup grew 24% year-over-yearfuelled by strong growth in Offshore Energy and Environmental of 57% and 48%,respectively.

Notably, Offshore Energy delivered strong turnover growth, accelerating the conversion of orderbook into turnover as it started to leverage its expanded

fleet capacity. The Dredging & Infra segment witnessed a boost in activity levels during the second half of the year, overcoming a -4% decline for the first half to a +5% growth over the full year. The Environmental segment sustained positive growth, primarily driven by its strong positioning within an increasingly stringent

DEME realised an EBITDA of 596 million euro in 2023 (18.2% of turnover), a 26% increase from 474 million euro (or 17.9% of turnover) in 2022, which included the liquidated damages associated with the late delivery of'Orion'.

EBITDA for Dredging & Infra demonstrated profitability improvement in the second semester driven by increased occupancy and a more favourable project phasing, resulting in an 18.6% EBITDA margin for the year. Also, the Environmental segment contributed a solid EBITDA margin of 16.8% reflecting successful project execution and the positive impact of the settlement on a completed project.

EBITDA for Offshore Energy improved during the second half compared to a relatively weak first half although EBITDA for the year was impacted by losses recorded on projects in the US and Taiwan(3). In the second half of the year, DEME sold 'Groenewind', an offshore service operation vessel, to Cyan Renewables for a gain on disposal of 13 million euro.

With a robust EBITDA, EBIT reached 241 million euro, or 7.3% of turnover, an increase of 55% from the 155 million euro, or 5.8% of turnoverrecorded in 2022.

Depreciations and impairments increased to 355 million euro compared to 319 million euro in 2022. The higherlevel of depreciation costs in 2023 is attributed primarily to the investments in 'Orion', DEME's largest offshore installation vessel, that was added to the fleet mid-2022, and in 'Viking Neptun', a cable laying vessel that was integrated into the fleet in the first half of 2023. The amount also includes a 13 million euro impairment for'Al Jarraf', one of DEME's cutter suction dredger vessels.

In 2023, the net results from joint ventures and associates amounted to 3 million euro, with the net result of the Concessions segment contributing 37 million euro compared to 9 million euro a year ago. This increase was partly driven by higher wind production, increased electricity prices, and the impact of new legislation in Belgium. However, the positive contribution from the Concessions segment was partially offset by the result of DEME's Taiwanese offshore joint venture company, which absorbed project losses on the Zhong Neng project in Taiwan.

The net profit for 2023 amounted to 163 million euro, marking a 44% increase from 113 million euro in 2022.

As a result, earnings per share were 6.43 euro compared to 4.45 euro in 2022 and 4.53 in 2021..(4)

The investments(5) in 'intangible assets' and 'property, plant and equipment', as of 31 December 2023, amounted to 399 million euro compared to 484 million euro a year ago.

Investments in 2023 included 'Viking Neptun', DEME's new cable laying vessel which was officially added to the fleet in the first half of 2023, capitalised maintenance investments in DEME's fleet, and modification investments and conversions for 'Sea Installer' and 'Yellowstone', a fallpipe vessel converted from a former bulk carrier and expected to join DEME's Offshore fleet in the first half of 2024.

Excluded from this investment amount is the expenditure for the 'Green Jade', the latest offshore wind installation vessel, which was constructed in Taiwan by CDWE, a joint venture between CSBC, the largest shipbuilder in Taiwan, and DEME and added to the fleet in the summer of 2023.

Operating working capital(6) amounted to -471 million euro as of 31 December 2023 compared to -506 million euro in the previous year.

The net financial debt(7) was -512 million euro as of 31 December 2023, a slight improvement of 8 million euro compared to 31 December 2022 and a reduction

of 203 million euro compared to 30 June 2023. Net financial debt over EBITDA at the end of 2023 was 0.86 compared to 1.09 a year ago and 1.41 at the mid-year point 2023.

Free cash flow(8) for the year was positive amounting to 62 million euro, up from -80 million euro the year before, mainly thanks to a strong cash flow generation in the second half of the year.

Based on the current interpretation of the rules regarding the EU Taxonomy, DEME's eligible activities expanded in 2023 beyond offshore wind and rail infrastructure to now also include parts of DEME's environmental activities, such as remediation of contaminated sites and soil and sediment management.

As a result of this expanded scope and stronger growth in eligible activities, 42% of the total turnoveris now eligible compared to 29% in 2022. 33% of the turnoveris now qualified as aligned compared to 26% last year.

Taxonomy-eligible and aligned capital expenditures remained in the same range at 49%, compared to 52% last yearin 2022.

In the sections below we provide some more insights on these developments.

DEME continued to execute its strategy to promote the transition to clean energy, installing more than 700 MW of wind turbines and 1,212 MW of foundations in 2023, compared to respectively 440 MW of turbines and 2,798 MW offoundations in 2022.

The total installed MW offoundations in 2023 were impacted by the mix of installation, mobilisations, and other works, including decommissioning, performed by

the primary vessels. These contributions in offshore wind farm projects were made in Europe (France, The Netherlands, Denmark and the UK, in Asia (Taiwan) and in the US.

The Dredging & Infra segment is engaged in constructing the Fehmarnbelt Fixed Link, the world's longest immersed road and rail tunnel between Denmark and Germany, promoting future sustainable trade and tourism,reducing travel time, and facilitating greener transport by

the use of electric trains. The segment is also advancing the design of the Princess Elisabeth Island in Belgium, the world's first artificial energy island and offshore energy hub and a key link in Europe's future North Sea energy grid. Main construction will start in 2024 and continue through 2026.

Finally, DEME is also actively engaged in diverse renewable energy initiatives, including the production and storage of green hydrogen.

To continue supporting the Group's short- and long-term growth, significant investments are being made in retaining and attracting human capital and talent. Several initiatives are underway,	with the most prominent being DEME's 'Where Next?' programme featuring targeted career days, participation in job fairs and events.		In 2023, the Group's workforce expanded reaching an average of 5,334 full time equivalents (FTEs), marking a 4% increase from the previous year.

Safety is ingrained in DEME's core values and evidenced in the worldwide LTIFR. The worldwide LTIFR for the year stood at 0.19, a notable improvement compared to 0.23 in 2022 and better than the target level of 0.20.

TheGroup intensified its focus on essential Safety Key Performance Indicators (KPIs), consistently meeting or surpassing targets for toolbox meeting participation, incident reporting, closure of action items, observations, inspections, and incident investigations.

(13) The Worldwide Lost Time Injury Frequency Rate (Worldwide LTIFR) is the metric reflecting accidents of employees and temporary employees involving work incapacity (≥ 24 hours or ≥ 1 shift) multiplied by 200,000 and divided by the number of hours worked. The 'Worldwide' method is a risk-based method that combines 'risk level rate' (= event that resulted in the injury) and 'injury rate' (= type ofinjury). To determine if an incident scores as 'Worldwide', the 'risk levelrate' and 'injury rate' are multiplied.

Sustainable innovation

The latest edition of the DEMEx programme which focuses on disruptive and transformational innovation, had its final showcase event in June 2023.

It was

a powerful illustration of how firmly innovation and sustainability are embedded in the heart and minds of the DEME team and made it tangible in powerful initiatives. Out of nine innovative ideas proposed at the final event, three were selected by theGroup's Innovation

Board to be further developed.

Board structure During the AnnualGeneral Meeting, held on 17 May 2023, the shareholders approved the appointment of Karena Cancilleri, as an independent directorforfour years.

To realise DEME's ambitious sustainability goals in all aspects of its activities, the Group converted its long-term financing into sustainability-linked loans in the course of 2022. This commitment underlines DEME's vision of achieving a sustainable future and at the end of 2023 represented a total value of 649.7 million euro. The commercial terms of those loans are directly linked to DEME's sustainability performance in two areas: (1) safety at

work and (2) use of low-carbon fuel, which are in line with two material topics of its current Materiality Matrix. Meeting or not meeting the targets set for key performance indicators (KPIs) have an impact on the interest margins applied to sustainability-linked loans. In 2023, DEME achieved the goal for both KPIs.

Regarding ESGassessments in 2023, DEMEGroup attained an 'A' – score from MSCI and a first Sustainalytics score as a separate company of 31.8. DEME Offshore received an Ecovadis silver medal, a shift from the gold medal in 2022 primarily influenced by a re-baselining of the assessment parameters. The Carbon Disclosure Project CDP score for DEME Offshore maintained a 'B'rating in 2023, mirroring the outcome from 2022.

Business ethics

Business ethics remains a consistent focal point for DEME, with ongoing refinement of compliance processes, exemplified by 99% of DEME's staff participating in the annual internal compliance training course.

02. Environmental challenges

Tackling polluted soil and the need to create and protect land

It is even more important today to value precious land resources and as the population continues to grow the demand for new residential or industrial areas will only continue. Therefore, it is crucial to be able to remediate polluted brownfield sites and give them a valuable new purpose. With the increasing focus on promoting a sustainable and circular economy, it is essential to clean and reuse as much of the cleaned material as possible.

01. Global climate change

Under the heading of global climate change, a number of challenges arise such as the need to limit emissions,rising sea levels, and the scarcity of mineral resources requird for the energy transition.

Reducing emissions & tackling climate change

The drive to achieve the ambitious goals of the Paris Agreement is becoming more urgent as countries try to slow global warming and move away from fossil-based fuels. The clean energy transition is seeing increasing demand for offshore wind energy and a focus on the importance of future fuels such as green hydrogen.

Rising sea levels and extreme weather events

With much of the world's population located along the coast and global warming leading to rising sea levels and more extreme weather events, the demand for coastal protection works is increasing, and there is a growing sense of urgency. DEME has been applying its proven coastal protection solutions for decades and in line with its sustainability goals, it is also looking for possibilities to use nature-inspired solutions. These re-examine traditional, unsustainable coastline and river embankment management methods and instead aim to develop circular, nature-based solutions.

03. Growing population and urbanisation

Growing population and urbanisation and the need for coastal protection and land reclamation

According to the UN, the global population is expected to climb to more than 9 billion by 2050. Currently around 40% of the population lives within 100 km of the coast and 10% live in coastal areas that are less than 10 m above sea level, leaving them highly vulnerable to sea-levelrise and other weather events such as storm surges. This means that flood defence solutions are vital and will become even more important in the future. Additionally, growing urbanisation makes it necessary to invest in land reclamation and new infrastructure.

04. Increasing maritime trade activity

Globalisation and the growth in world trade and its impact on marine infrastructure

Over the past decades, globalisation has led to a substantial increase in international trade between countries worldwide, which in turn means that existing supply chains and trade routes are developing, and new ones are being created as geopolitical and macroeconomic forces shift current trading patterns. This requires new ports or the expansion of existing facilities, together with their access channels and other marine infrastructure.

Another major trend is that vessels – whether containerships, bulkers or tankers – are getting bigger. Berths, fairways and turning basins have to be dredged and widened to accommodate the next generation of vessels.

Scarcity of mineral resources & increasing electrification

The growth in the world's population, urbanisation, increasing wealth and the energy transition are leading to unprecedented demand for electrification and in turn, the demand for minerals. Many of today's clean energy technologies

are reliant on the plentiful supply of critical minerals. For example, the International Energy Agency forecasts that to meet climate goals, cobalt supply will need to increase 21-fold and nickel 19-fold by 2040.

1. The best people

The best people in the industry

Our 5,300 highly skilled professionals demonstrate their innovative, entrepreneurial spirit every day – continually pursuing operational excellence and always with the legendary 'can do' attitude. They strive to find smart solutions for our customers, even when faced with seemingly impossible challenges.

The diverse fleet includes groundbreaking vessels such as 'Orion' and 'Green Jade', which bring a game-changing floating installation concept to the offshore energy market. DEME also operates 'Spartacus', the most powerful mega cutter suction dredgerin the world, and two state-of-the-art cable layers, which have unrivalled cabling capacity. Soon the fleet will also be joined by 'Yellowstone', the largest fallpipe vessel in the sector.

With DEME's ambition to have the most sustainable fleet in the industry, several vessels already have dualfuel engines and are capable ofrunning on the cleanest fuels available, and indeed two feature a hybrid power plant. Additionally, 'Yellowstone' will actually be the first in the fleet to be prepared for(green) methanol.

Listening carefully to customers, DEME continuously invests in upgrading its vessels to meet future demands. One example is the upgrading of'Sea Installer' and 'Sea Challenger' by boosting their crane capacity to 1,600 tonnes so they are fully prepared for the next generation of XXL offshore wind farm components.

Second DP3 floating offshore installation vessel joins the fleet

Able to perform floating offshore installations, particularly foundations for the largest wind turbines, the DP3 monohull heavy lift vessel 'Green Jade' entered service in July 2023, and went directly to its first project, smoothly installing the first jacket foundation at the Zhong Neng offshore wind farm in Taiwan.

Built to handle the next generation of mega wind turbines,foundations and components, and owned by the joint venture CSBC-DEME Wind Engineering Co Ltd (CDWE), 'Green Jade' is equipped with a 4,000-tonne,fully electric crane. The new vessel proved its capabilities straight away, lifting and installing the 2,000-tonne foundations at Zhong Neng with ease, and despite challenging weather conditions, the 'Green Jade' experienced little downtime.

The newbuild is designed to work in deeper waters and difficult environments such as those found in Taiwan, which can be prone to earthquakes and typhoons. These conditions mean that jacket foundations are used instead of monopiles and given this requirement, 'Green Jade' is equipped with an enormous, obstacle-free deck for the mega foundations, and it has an exceptionally high load capacity.

'Green Jade' is equipped with an efficient powerplant and has several innovative sustainable features such as a waste heat recovery system that converts heat from the exhaust gases into electric power that can be used aboard. As the vessel has a fully electric crane, significant fuel savings are also possible.

Following on from Zhong Neng, 'Green Jade' is set to work on the Hai Long wind farm in Taiwan, which will generate more than 1 GW of clean electricity.

DEME Fleet

With more than 100 specialised vessels in its fleet, DEME undeniably has the most modern and technologically advanced fleet in the industry. The ongoing investment in its fleet ensures that DEME anticipates the future needs of its customers, and that it can achieve its ambition of becoming carbon neutral by 2050.

Boosting crane capacity of 'Sea Installer' to handle XXL turbines

Addressing growing demand with DP3 cable laying vessel 'Viking Neptun'

'Viking Neptun' is the second major DP3 cable laying vessel in the DEME fleet. Built to Norwegian quality standards, the offshore installation vessel was acquired from the Norwegian shipping company Eidesvik. The vessel performed its first assignment for DEME in 2023, installing inter-array cables for Dogger Bank, which is currently the largest offshore wind farm in the world.

The DP3 vessel – just like DEME's renowned cable layer'Living Stone' – has a very high cable carrying capacity of 4,500 tonnes below deck. However, DEME will boost this capacity substantially by adding a second 8,000-tonne cable turntable on deck in 2024.

In a first for the DEME fleet and highlighting the company's efforts to have the most sustainable fleet in the industry, 'Viking Neptun' has a hybrid power plant with a large battery pack of 1.7 MWh installed. This allows the vessel to run on diesel or batteries, leading to substantialfuel savings of 10-15%.

Fully compliant with international environmental standards, 'Viking Neptun' features advanced technology resulting in efficiency gains and fewer emissions, such as a combinator curve for the main propeller and a smart ventilation system.

Impressive power of 22,700kW is combined with great seakeeping and DP abilities, enabling the vessel to work in the harshest conditions. At 145 m in length, 'Viking Neptun' has a spacious, unobstructed deck and a 400-tonne active heave compensated knuckle boom crane.

As well as the upcoming cable carrousel, DEME has already equipped the vessel with a complete cable installation system, including stainless steel cable laying chutes over the stern. A high-capacity trencher to plough a route in the seabed is due to be added in the future.

Having two of these mega cable layers in the fleet allows DEME to be even more flexible, enabling the company to swiftly respond to customer demand.

In order to be able to handle the XXL offshore wind turbines of the future, DEME's well-known turbine installation vessel 'Sea Installer' successfully underwent a major upgrade that boosted its crane capacity to 1,600 tonnes, amongst otherimprovements.

The new crane is a fully electric leg encircling crane with an ultra-long boom. In addition, Sea Installer's beam was increased by 7 m by adding sponsons on both sides. The spud legs were extended by 10 m, the jacking system was upgraded, a water ballast treatment plant was added and the accommodation capacity increased. Sea Installer's sister vessel, 'Sea Challenger' is also set to undergo the same conversion.

'Yellowstone', largest DP2 rock installation vessel in the world set to join the fleet

In order to quickly gear up forincreasing demand for scour protection and rock dumping, DEME is investing in the biggest DP2 fallpipe vessel in the world. The new fallpipe vessel is idealfor the longer transit times needed in the US offshore wind industry for example.

A former Supramax bulk carrieris being converted into a 192-m fallpipe vessel that will boast an enormous payload of 37,000 tonnes - doubling the capacity of DEME's existing vessels. The conversion will include a new powerplant and (DP) propulsion system, the creation of two large rock holds with an ample sized moonpool in between,rock handling systems, as well as an upgrade of the accommodation and the construction of a new bridge.

In line with DEME's vision to become climate neutral by 2050 and ambitions to have a net zero GHG vessel, the fallpipe vessel will be the first in the fleet to be prepared for(green) methanol. Additionally, 'Yellowstone' will have a hybrid power plant with a 1 MWh Li-ion battery, making it possible to achieve 10-15% in fuel savings, especially in DP mode.

'Yellowstone' is being equipped with a central verticalfallpipe for water depths of 600 -700 m. A large inclined fallpipe, designed for shallow depths of 30 – 50 m, is also being installed, making it much easier to get closer to monopiles when placing scour protection.

The fallpipe vessel will join the DEME fleet in the coming months.

Our specialised geophysical survey subsidiary, G-tec, expands its service offering with the addition of'Karina', a new geophysical survey vessel.

'Karina' boasts a permanent suite of cutting-edge technology, including a hull-mounted dual-head multibeam, side scan sonar, sub-bottom profilers, magnetometers, and gradiometer frames. This comprehensive outfitting allows the vessel to tackle a wide range of projects, including UXO (Unexploded Ordnance) surveys.

Particularly well-suited for 2D and 3D Ultra-High Resolution Seismic (UHRS) acquisition, 'Karina' excels due to its exceptionally low acoustic signature. Additionally, the vessel operates with fuel efficiency, even at high speeds, with the capability to run entirely on biofuel, minimising environmental impact.

This DP2-equipped 55 m vessel enters service in 2024 and will immediately start working on a series of planned geophysical survey projects.

Expanding capabilities with geophysical survey vessel 'Karina'

Ultimately, innovation enables DEME to work towards its sustainable goals to create a cleaner, greener planet for generations to come. One way DEME stimulates innovation is through its disruptive, transformational programme, DEMEx. This initiative, which is launched every four years, aims to create new business by imagining future worlds and offers smart solutions to global challenges.

Hundreds of new ideas are suggested by employees during the initial phase and the DEME Innovation Board then selects those ideas that have the most potentialfrom different points of view.

Answering the demand for clean energy

A major global challenge is of course, climate change and extreme weather events. Given DEME's remediation and environmental expertise, two teams

are now working on the development of ground-breaking solutions in this context. Then with the demand for clean and stable energy supplies, a third team is developing a novel energy storage solution.

Crucially, the DEMEx campaign and other innovation initiatives are an important part of the culture of the Group. DEME encourages the younger generation to anticipate future trends and challenges and come up with solutions. This innovative culture not only helps DEME attract youngsters who want to work for such a progressive company, but in turn, it helps DEME attract talent and retain it; vitalfor a sustainable company.

By imagining future worlds and by working together to find business opportunities and sustainable solutions, it is a win-win for both DEME and our planet.

Additionally, DEME regularly launches

fast-track 'Alternatives, Value, Innovation, Smarts and Optimisations' (AViSO) campaigns for specific challenges such as underwater data centres, landfill redevelopment and wave energy.

In 2023, the Innovation and Sustainability teams also worked together to support the DEME 'Captains and Chief Engineers' Summit. The company is aiming to reduce greenhouse gases on an operational and technical level and recognises that the crew is an invaluable source of great ideas to support DEME becoming more sustainable.

Fostering partnerships that drive innovation

Acknowledging that addressing global challenges requires collaboration, the company is also adopting a more open approach to innovation and exploring opportunities with external partners such as port authorities and utility providers.

1. Technical leadership

Leveraging innovation to tackle global challenges

DEME is renowned for its innovative thinking, enabling the company to excel in technological advancements and pioneer into new markets. This capability has solidified DEME's position as a front runner.

DEME already has a very high maturity level in terms ofinnovation but by working together with strategic partners with different perspectives, DEME is sure that solutions can be found more swiftly.

Our partnership with Foss Maritime for the Vineyard Wind 1 offshore wind farm is an example of such collaboration. The groundbreaking feeder barge concept we developed togetherfor the US offshore wind market represents cutting-edge engineering, patented solutions, and tailored modifications to ourrespective vessels.

Another example is the offshore foundation drill we developed with Herrenknecht to installfoundations at the Saint-Nazaire offshore wind farm in France. The offshore foundation drill has successfully demonstrated its capabilities and will again be deployed at the Noirmoutier offshore wind farm.

Focus on operational excellence

Throughout the organisation, DEME continuously seeks to improve its performance year after year. This commitment is exemplified by our company-wide and multi-year'Digital Vision' programme, aimed at aligning our operations to support future growth. This comprehensive initiative encompasses various aspects, including the optimisation of processes, establishment of a digital workplace, and data-driven decision-making to fosterintegrated insights and facilitate swift value-driven actions. In pursuit of

these goals, we collaborate with leading IT and AI partners such as Microsoft. Another significant endeavouris the 'Fleet Efficiency Programme', a two-year transformation initiative launched in 2023. This programme aims to overhaul DEME's maintenance processes, encompassing routine maintenance, majorrepairs, and organisational oversight. The overarching objective is to ensure the reliability of DEME's vessels while enhancing efficiency and cost-effectiveness to support the company's future expansion.

Additionally and as a result of a continued, disciplined capital allocation policy, the company has a healthy balance sheet and a sound debt level, allowing it to continue to invest in its mid- and long-term future, and to move swiftly when opportunities arise. The company maintains strict discipline regarding its debt position and remains below the limit of net financial debt over EBITDA below 3, as set forth in the covenants.

How DEME is organised

DEME has evolved into a global provider of sustainable marine solutions, structured into four distinct segments, each serving a specific market and operating with its own unique assets, revenue model, and growth strategies.

The Environmental segment focuses on innovative environmental solutions for soilremediation and brownfield redevelopment, environmental dredging, sediment treatment and water treatment. The segment primarily operates in the Benelux, France, and across other European countries on a project-by-project basis.

Dredging & Infra

Across the globe, DEME carries out a comprehensive range of dredging activities, including capital and maintenance dredging, land reclamation, soil improvement, port construction and coastal protection. These activities are executed with a fleet of specialised dredging vessels, various types of auxiliary vessels and earthmoving equipment. The segment also provides contracting services for marine infrastructure projects. This includes the engineering, design and construction of complex marine structures such as jetties,

port terminals, locks and weirs, infrastructure works such as bored and immersed tunnels,foundation and marine works for bridges or other constructions in a marine or fluvial environment and civil works for harbour construction, dams and sea defences, canal construction, revetment works, quay wall construction and shore protection. In addition, DEME is active in the marine aggregates business, which includes the extracting, processing, storage and transport of aggregates. Finally, DEME provides maritime services for port terminals.

Concessions

The Concessions segment, unlike the contracting segments, invests in and develops projects in offshore wind, port infrastructure, green hydrogen and other special projects. It operates through participations in special purpose companies – greenfield and brownfield. In addition to creating economic value on its projects and generating equity returns on its investments,

the company also aims to secure contracting activities for the Group in the EPC phases ofits projects. Under the umbrella of this segment, DEME also holds concessions of seabed areas which contain polymetallic nodules and develops a technology to collect and process these polymetallic nodules containing nickel, cobalt, manganese and copperfrom the deep ocean floor.

Offshore Energy

The Offshore Energy segment provides engineering and contracting services globally in the offshore renewables and non-renewables industry. These activities are carried out with a fleet of specialised offshore vessels. In offshore renewables, the segment is involved in full EPCI contracts for offshore wind farms. This includes the engineering, procurement, construction and installation of foundations, inter-array cables, export cables and substations.

In the non-renewables industry, the segment performs landfalls and civil works,rock placement, heavy lift, umbilicals, as well as installation and decommissioning services. Furthermore, the segment also provides geoscience services and the installation of suction pile and anchors.

Performance dashboard

Segment performance 2023

The Offshore Energy segment

increased its orderbook by 15% and grew revenue 57% year-over-year, driven by continued solid demand and reflecting the expanded fleet capacity, coupled with robust project execution.

In addition to solid results, 2023 was also a year of operational accomplishments for DEME Offshore Energy. The segment entered into two new geographies, continued to strengthen the organisation and expanded the fleet with 'Viking Neptun', a cable laying vessel, and 'Green Jade', an additionalfloating installation vessel, amongst others. 'Orion', which was added to the fleet mid-2022, continued to demonstrate and affirm its technical capabilities and the advantage of the floating installation concept.

'Green Jade' was added to the fleet in June and performed well on the Zhong Neng project in Taiwan, installing jackets. These works will continue during the first quarter of 2024, after which 'Green Jade' will commence the Hai Long project.

In the US, Offshore Energy delivered its "first steel in the water" already before summer, pioneering the adoption of offshore wind in the US market. 'Living Stone' completed the cable installation works for the South Fork project during 2023 and preparations

are on track with Dominion Energy for the Coastal Virginia project for a 2.6 GW wind farm with 176 wind turbines, to kick-offin the first half of 2024. On the Vineyard Wind 1 project and while negotiations on variation orders are still ongoing, the works progressed well in the second half of the year with 47 of 62 monopiles and 30 transition pieces installed by 'Orion', a string of turbines installed by 'Sea Installer' and the first part of the wind farm operational and connected to the grid. For both the Vineyard Wind 1 and the Zhong Neng project, losses to completion have been accounted forin 2023. These losses to completion have been partially offset by expected turnoverincluding specific variation orders, that are pending approval, and have been assessed in line with IFRS standards (IAS 37). This assessment is supported by solid legal opinions.

In Europe, the segment successfully completed installation projects in Denmark and the Netherlands while extending its presence in France. The vessel 'Innovation' made significant progress on the Fécamp project and is gearing up for the commencement of the Île d'Yeu and Noirmoutier projects in early 2024. In the UK, the segment continued its inter-array cabling works for the Dogger Bank and Nearth Na Gaoithe projects, along with initiating preparatory works for the Moray West project.

In the non-renewables, the segment continued its activities at the Hinkley Point nuclear power plant in the UK, completing the drilling of the shafts for the intake and outfall structures.

Vessel occupancy for the Offshore Energy segment was higher compared to 2022, mainly driven by increased utilisation across the globe in the second half of the year and following a period of technical upgrades to the vessels in support of project requirements.

The increase in the Offshore Energy orderbook was fuelled by new contract awards, with project deployments over the next few years, including sizeable project wins such as a cable contract for Baltic Power, DEME's first offshore wind farm project in Poland, contracts in France for the Dieppe Le Tréport, Île d'Yeu and Noirmoutier offshore wind farms and the Greater Changhua contract in Taiwan with the Taiwanese joint venture CDWE. In the non-renewables in North America, Offshore Energy also added the Cenovus White Rose project in Newfoundland in Canada. These additions to the orderbook largely offset the cancellations of both the Norfolk Boreas and Empire Wind 2 projects received in the course of 2023.

Proven track record sees DEME perform largest inter-array cable project at Dogger Bank

With a proven track record in delivering large inter-array cable scopes and already firmly established as the leading offshore wind contractor, DEME is currently performing the largest ever inter-array cabling project in history for the world's biggest wind farm – the 3.6 GW Dogger Bank in the UK. Being built in three 1.2 GW phases, Dogger Bank A, B and C, the project is a joint venture between SSE Renewables, Equinor and Vårgrønn.

Seen as a significant step forward in developing more secure and affordable UK energy, Dogger Bank is located off the Northeast coast of England and is set to generate enough energy to power more than 4.5 million homes a year – around 5% of Great Britain's electricity needs. With the location 130 – 200 km from the shore, Dogger Bank is by far the furthest wind farm offshore.

650 km of cables

DEME Offshore Energy was awarded the original EPCI orderin August 2020 for Dogger Bank A and B,representing 650 km of 66 kV inter-array cables. DEME is responsible for manufacturing, supplying, installing and protecting the cables and allrelated accessories. Then in August 2021, DEME Offshore secured the contract for Dogger Bank C, this time for 250 km ofIAC. Separately, DEME carried out a foundation installation campaign and is involved in the scour protection.

These contracts demonstrate the unrivalled capabilities of DEME Offshore and the dedicated fleet of specialised vessels it has for these demanding projects.

Unrivalled cable laying capacity

In December 2022, the team carried out the first loadout of the inter-array cables at Hellenic Cables in Greece. DEME brought in its new DP3 cable laying vessel for the project, 'Viking Neptun'. Built to Norwegian offshore quality standards, 'Viking Neptun'– just like DEME's renowned cable layer'Living Stone' – has a very high cable-carrying capacity. DEME has equipped the new vessel with a complete cable installation system and will soon boost capacity with the addition of a second turntable on the main deck.

With a very efficient hybrid powerplant, DEME's new cable layer can work forlonger periods in harsh weather conditions and during the winter months, idealfor Dogger Bank. A highly experienced crew is ensuring that the first phase of the cabling campaign for Dogger Bank remains on track. Both DP3 vessels travelled from DEME Offshore's main base in Flushing in the Netherlands to Hellenic Cables and picked up several batches of cables to temporarily store them in Amsterdam until pick-up for installation on the project site. Using the vessels' vast capacity, DEME has been able to reduce the time spent on trips between Greece and the UK to a strict minimum.

DEME Offshore's ability to be flexible and agile is proving vital to ensure the steady progression of the project.

One project team managing all the interfaces

As well as the challenges because of the distance offshore, the sheer number of cables and the interfacing between all the various parties, are other aspects of the project that demonstrate DEME's project management skills. The scope is not just the actual cable laying, but the procurement, preparation of the seabed and the towers, the cable pull-ins, burial, pre- and post-lay surveying, and the testing of the cable system – all to be aligned with a developing project schedule. These aspects are all managed by DEME Offshore, and this requires a close-knit,fully aligned team.

One project team has been established for all three phases of Dogger Bank project to optimise synergies and take on board lessons learnt for the next phase. DEME works closely with all ofits partners in the supply chain. For example, there is very good cooperation and frequent dialogue with Hellenic Cables at project level, but also at all levels of management of both companies.

Taking its legendary 'can do' approach, DEME Offshore does everything it can to accommodate and support its customer and the UK supply chain. The Dogger Bank team is a mix of very experienced people and enthusiastic youngsters, and the project management team and business unit cables make sure everyone is focused and that there is a great team spirit to maintain top levels of productivity.

DEME Offshore understands that a mammoth project such as Dogger Bank is 'a marathon, not a sprint'. But its people are all motivated 'endurance runners', able to perform from day one of preparations for Dogger Bank A to the last minute of the last day of Dogger Bank C.

Delivering engineering excellence towards net zero at Hinkley Point C

DEME is on the frontline of seeing the impact of climate change and its teams are actively engaged in providing sustainable solutions to help combat global warming. A key part of its vision is to support, and even accelerate, the clean energy transition as the world considers alternative low-carbon energy sources instead of traditional fossil fuels.

Many of DEME's projects across the globe are helping various countries as they strive to achieve their net zero goals. This is demonstrated by one of the most complex marine engineering projects taking place today – the Hinkley Point C nuclear power plant in the UK. DEME's highly skilled team is playing a key role in the marine construction part of this five-year project.

Located in Somerset, and being built with a lifespan of 60 years, Hinkley Point C is considered a vital piece of critical infrastructure for the UK's energy future and in the country's shift away from fossilfuels.

Installation in shallow water

DEME's prowess in the offshore wind industry is well known – being the number one contractor- but Hinkley Point C highlights that DEME has a vast range ofin-house expertise. Almost uniquely, DEME has the ability to perform dredging, backfilling, heavy lift,rock placement, piling and drilling. At Hinkley the team was lifting and installing heavy structures within tolerances ofjust centimetres and all of these activities were also carried out in shallow water areas.

The international infrastructure group Balfour Beatty originally appointed DEME as a subcontractorfor Hinkley Point under an Early ContractorInvolvement (ECI) agreement in 2017. Hinkley Point C involves the construction of three tunnels under the seabed that will supply two reactors with cooling water, before discharging it back into the Bristol Channel. In this staggering engineering feat, three tunnels,representing approximately 9 km in length will be constructed, and they will be lined with 38,000 concrete segments.

They are then connected to the seabed by vertical shafts and capped with giant intake and outfall heads (fourintake and two outfall heads) that allow seawater to pass into the tunnels. The largest head is 44 m long and weighs nearly 5,000 tonnes.

DEME was awarded all the marine works, encompassing dredging six pits required for the construction of the fourintake and two outfall structures and the complex dredging campaign to prepare the seabed for the installation of the six tunnel heads. DEME is also responsible for the placement of the pre-cast gravity-based structures, large diameter piling and the construction of shafts and liners. These liners connect the intake and outfall structures with the tunnels bored below.

The first dredging campaign took place in 2018 and the intake and outfall structures were installed in 2022. The last liner was successfully installed and grouted in December 2023.

Unique tandem lift

Initially in 2018, DEME mobilised its hopper dredger 'Artevelde' to commence the first dredging campaign and to check for the ingress of sedimentation. In 2021, 'Artevelde' was remobilised again, together with the backhoe dredger 'Peter the Great' to prepare the seabed. The specialised vessel 'Naseem' then installed the gravel bed to an extremely precise tolerance to ensure that the intake and outfall heads were perfectly leveled. After extensive training of the crew at DEME's simulation centre in Antwerp and full-scale lifting tests conducted offshore, DEME deployed two heavy lift vessels in a unique tandem lift setup ('Gulliver' and 'Rambiz') from its sister company Scaldis Salvage & Marine Contractors NV (Scaldis) to lift and lower the huge 5,000-tonne structures into place.

The six intake and outlets represented an impressive total weight of 25,000 tonnes and these were installed on the seabed within tolerances ofjust 20 cm, even though the specifications demanded a 1 m accuracy. Additionally, these operations were performed in significant currents and difficult tidal conditions. A 10 m tidal difference in some of the estuaries with vessels on 16 anchors made the work particularly challenging.

Once the concrete structures had been placed, they were protected with scour protection, which was installed by 'Naseem' in a 24/7 operation.

Expert engineers

The final stage of the marine scope ended in December 2023 when DEME completed the installation and grouting of the six liners. The jack-up vessel 'Neptune' commenced this last phase of operations in early 2023 by installing casings through the pre-fitted holes in the middle of the respective intake and outfall structures. The casings were

thereafter encompassed by a retractable outriggerframe fitted alongside 'Neptune' and piled to the target depth.

A dedicated XL drill, which DEME designed with its partners, was deployed from the 'Neptune' and after completion of the drilling, DEME's DP2 jack-up vessel 'Sea Challenger' lifted the 340-tonne liners and lowered them down in the pre-drilled hole. DEME's engineers also designed the lifting tool for the casings, liners and associated components. The structures were installed 35-40 m below the seabed in 6.5 m wide shafts. The annulus between the liner and the drilled hole would subsequently be filled up with grout (approximately 120 m3 per location).

This complicated project highlights the engineering skills of the DEME team and their ability to handle extremely

complex methodologies. A wide variety of DEME engineers were working on the project, including civil, mechanical, and chemical engineers. As well as the expert engineering knowledge, this project demonstrates the capability of DEME's highly skilled crews. In addition to the challenging tidal conditions and currents, they had to carefully navigate between several vessels.

Minimal interfaces

Known for its innovative spirit and its dogged pursuit of smart solutions, very few companies in the world are able to carry out the combination of precision dredging operations, gravel bed installation, heavy lifting operations in shallow water, a complex dual lifting campaign, drilling, and subsea grouting. All of this has been carried

out with precision accuracy and while complying with the most stringent safety precautions in the offshore industry.

It is undoubtedly an extraordinary feat considering that most of the project's scope was taking place in challenging conditions, with shallow and extreme tides of seawater above, and in very strong currents. Undoubtedly the success is also due to an extensive period of Early ContractorInvolvement, which took place prior to the commencement of the works. During this period the methodologies were discussed and finalised within the constraints of the required lifetime and nuclearindustry requirements.

The project is now fully prepared for the next stage, during which Balfour Beatty will establish the connections between the tunnel and the liners.

Project showcase

Drilling expertise overcomes rocky seabed challenges at Iles d'Yeu and Noirmoutier wind farm

With little doubt that offshore wind power is crucial if the world is to achieve the energy transition, DEME is proud to have been an early pioneer in this industry. More than two decades ago, DEME was already constructing one of the first wind farms in the North Sea. Since then, it has built up an unrivalled portfolio, constructing more than 90 offshore wind farms worldwide, which in turn contributes 30 GW of green energy.

But now the sector has matured - at least in the context of Northern Europe – many of the current projects and those in the pipeline are more demanding, given the complexity of the technical and engineering challenges. They require a highly experienced contractor and an expert team of professionals able to provide innovative solutions based on the knowledge built up through every phase of the development of the offshore wind sector.

Until now,foundation installation at most of the wind farms in Northern Europe has been relatively 'straightforward' – close to shore, in shallow waters, benign seabed conditions etc. But the industry has stepped up a gear and a new era of more difficult wind farm developments has emerged such as some of those in France where XL foundations have to be drilled directly into rock. Additionally, floating wind farms are being designed as offshore wind enters the next phase.

Complicated substrata and locations exposed to oceanic conditions from the Atlantic are certainly defining several upcoming projects in France, and generally future locations in Europe are going into deeper waters. As well as this, the foundations being constructed are for bigger, more powerful turbines. This, in turn, means largerinstallation vessels and enhanced port facilities.

Saint-Nazaire drilled directly into rock

While a handful of companies can handle this new generation of projects, at the moment there is only one company that has successfully drilled XL monopile foundations directly into rock – and that is DEME.

Constructed in 2022, and afterfour years of preparation, Saint-Nazaire comprised 80 foundations. At the time, the industry was very sceptical that it could ever be built, believing it was impossible to drill XL monopiles into rock. However, by working proactively with the customer and being willing to take the time to invest in new industry-first equipment and techniques, DEME proved that it was possible.

As no contractor had ever drilled such enormous foundations directly into rock, there was no suitable equipment in the market. But DEME's talented people and the company took the decision to manufacture its own dedicated equipment.

A unique drilling spread consisting of two specific innovations led to the completion of the momentous task in just 13 months: a giant 350-tonne Offshore Foundation Drill (OFD) and the so-called 'MODIGA'. The drill was designed together with partner Herrenknecht, the global leaderin tunnel boring machines, and at 50-m high, the MODIGA encapsulated the drilling, installation and grouting operations, protecting them from the harsh Atlantic conditions.

The MODIGA served as a guide for the drilling machine and at Saint-Nazaire it could already reach depths of 25 m. It also provided a much-needed shelter when the grouting – representing a total of 30,000 tonnes across the entire wind farm - was taking place. Another key tool was a gigantic grouting plant, which is the biggest ever used offshore, with an unbeatable capacity of 100 tonnes per hour.

Unique, powerful drilling spread

This drilling rig is twice as powerful when compared to any spreads currently in the market, allowing the offshore team to work swiftly and dramatically reduce downtime as a result of bad weather. Saint-Nazaire highlights DEME's ability to dare to pioneer and this is supported by its willingness to make the large investments needed to achieve significant strides in production capacity offshore.

As well as exceptional equipment, the most important factor that made the difference was the highly experienced captain and crew of DEME's jack-up vessel 'Innovation' and the operations team, who managed to achieve terrific production rates, even though they were working in the notorious long swells of the Atlantic.

Certainly, industry eyes were upon DEME as it embarked on this project. Having proven its methodologies and

delivering Saint-Nazaire even earlier than planned, new contracts have followed.

Rocky seabed at Iles d'Yeu and Noirmoutier

In 2023, DEME was awarded contracts for the Iles d'Yeu and Noirmoutier wind farm – again another challenging location where the XL foundations have to be drilled into rock. The award includes the transport and installation contracts for the foundations and the offshore substation.

The special drilling rig and methods developed at Saint-Nazaire will again be deployed. However, the MODIGA has been adapted and lengthened to 60 m, and can now reach depths of 35 m.

Logistics are also a major challenge for the new project given the 1,000-tonne, 70-m long foundations. These are being shipped from China into La Rochelle and temporarily stored at the port. DEME is responsible for offloading them at La Rochelle and then loading them onto the installation vessel.

Technical competence and managing risks

The key members of the Saint-Nazaire team are also leading the Iles d'Yeu and Noirmoutier wind farm project which is due to get underway in 2024. As the start date approaches, DEME is certain that its strengths – talented people, innovative thinking, technical competence and the ability to manage risk - will enable the company to deliver another complex wind farm safely and successfully.

DEME is ready for the upcoming challenges of the rocky seabed of France, and further afield as countries like Japan embarks on its next round of offshore wind concessions.

Segment performance 2023

Dredging & Infra reported a turnover of 1.6 billion euro, 5% higher than 2022. Orderbook increased 33% compared to the previous year.

The segment continued to perform underlong-term maintenance dredging contracts in Europe including different seaports in Belgium. In Germany the segment added both maintenance and new capital dredging work, expanding its presence around the River Elbe between Hamburg and the North Sea. The segment also completed the dredging works for a new container terminal in Gdansk in Poland, started dredging hard rock in the port of La Pallice in La Rochelle in France and continued the modernisation works for the port of Ravenna in Italy.

Overseas, the segment finished the works on a container terminal in Sri Lanka and continued working on several projects in West Africa and maintenance dredging projects in India. The segment also continued capital dredging and land reclamation works for the extension of the port of Abu Qirin Egypt and executed dredging and reclamation works in Abu Dhabi deploying multiple trailing suction hopper dredgers and mega cutter suction dredgers. In Saudi Arabia, the preparatory activities for the Oxagon Phase 2 project were immediately initiated following the contract award in the last quarter of the year.

Large ongoing marine infrastructure projects testify to DEME's unrivalled immersed tunnel expertise. In the Netherlands, the two tunnel elements for the Blankenburg project were successfully installed and the project is now expected to be completed in the summer of 2024. On the Fehmarnbelt Fixed Link project (Denmark), production of the tunnel elements has started in preparation for the first installation during the second half of 2024. In Belgium, DEME is a member of two consortia for the Oosterweel Connection project. One consortium is overseeing the construction of an immersed tunnel in the River Scheldt to complete the Antwerp Ring Road, while the otheris responsible forinfra works on the right bank of the River Scheldt. Furthermore, in France the port development in Port-La Nouvelle advanced, and in the Netherlands the New Lock Terneuzen project entered its final stage.

The EBITDA margin in the Dredging & Infra segment increased from 16.7% in 2022 to 18.6% in 2023. Vessel occupation for the full yearremained stable for the trailing suction hopperfleet and decreased for the cutterfleet although occupancy increased in the second half

of the year,following a relatively higher level of maintenance activities on the fleet in the first half of the year and driven by a surge in demand and contract wins.

The orderbook increased 33% to 3,472 million euro. Additions to the 2023 orderbook include the new Princess Elisabeth Island, the world's first energy island,for which the first caissons will be installed in the course of 2024, as well as prolonged maintenance projects in Belgium for the River Scheldt and several ports.

Additionally in Europe, the Dredging & Infra segment capitalized on its presence in Italy and around the River Elbe,resulting in new projects. Other noteworthy wins overseas include contracts in the Indian subcontinent, the Maldives and West Africa. At the end of the year, a consortium including DEME, was awarded a large contract for the second phase of capital dredging works and construction of the Port of NEOM in Saudi Arabia.

Local and national economies benefit from DEME's port expansion expertise

According to the United Nations (UN), the global population is expected to reach a staggering 9.8 billion by 2050. This rising population is leading to a significant growth in world trade and further globalisation that result in existing supply chains being extended and new trade routes being developed. All of this has a significant impact on marine infrastructure.

Restructuring the Port of Ravenna in Italy

The Port of Ravenna has always played a crucial role in the economic development of Italy even since Roman times and that is still true today, being a thriving commercial and industrial maritime hub and a key gateway for Italian exports.

In two separate projects, DEME is very pleased to be assisting both the port authority and alongside that, the Italian gas grid operator Snam, which is investing in a new liquefied natural gas offshore Floating Storage Regasification Unit (FSRU) terminal near Ravenna.

Awarded in late 2020, DEME, together with its Italian joint venture partner Consorzio Stabile Grandi Lavori, is performing a multi-year design & build contract for the entire restructuring of the Port of Ravenna. This large-scale project enables its customer, the port authority, to continue to build on the port's legacy and maintain Ravenna as a key industrial and commercial hub in the Adriatic region. Taking place at the same time, the Snam project facilitates Italy's ambitions to achieve energy independence by increasing its gas import capacity and having a more diverse range of energy supplies.

Multi-year design & build contract

In the first phase of the Ravenna port project, DEME is initially dredging from -11 m to depths of -12.5 m and then in a second phase, the company will dredge up to -15.5 m. Ultimately, the port will be able to handle much larger vessels of 75,000 deadweight tonnage (dwt) and containerships of up to 8,000 twenty foot equivalent unit (teu). The partners will also construct a new 1,000 m quay for the Peninsula Trattaroli, which serves as a new port area.

The scope includes all the dredging activities to deepen and widen the port and access channel and DEME is also managing and transporting the material to various reclamation areas located inland.

Two types of dredging activities are involved at Ravenna. Hydraulic dredging is performed by hopper dredgers and organised in various campaigns. To date, the hopper dredgers 'Bonny River' and 'Nile River' have been deployed. Alongside the hoppers, mechanical dredging is continuously performed by grab dredgers and takes place in specific parts of the port.

Ports worldwide expand to accommodate larger ships, driving local and national economic growth through new jobs, infrastructure improvements, and boosted trade. Recent projects showcase DEME's expertise in making a difference in port expansion projects.

DEME's hopper dredger, 'Bonny River', which has a capacity of 15,000 m 3 , kicked off the hydraulic dredging campaign in March 2022. Eventually 7 million m 3 will be dredged overall, of which 1 million to 1.5 million m 3 will be treated onsite using a soil treatment plant provided by another contractor who was awarded the dedicated tender independently.

The Ravenna project is particularly complex because of the nature of the dredged material. Contaminated material is not dumped offshore but is instead carefully sorted out and transported to special inland disposal sites. Only clean material is going to designated offshore locations. As such, the dredging activities are preceded by an exhaustive soil characterisation process and various analyses of the contamination levels of the material are done before it is sent to the appropriate site. It is worth noting that part of the dredged material is being used to refill an old quarry. DEME is delighted that it can support the local authority by creating new land and breathing new life into the abandoned quarry. The smooth execution of this scope is only possible because of the management of the interfaces between the dredging team and the land activities, and by working very closely with its local partners, the Port Authority and the regional Environmental Agency to ensure full alignment.

Ahead of schedule

Despite the complexities, the Italian team is powering ahead and is looking to complete the project at the end of 2026. DEME is doing everything it can to speed things up to fulfil its customer's wishes, with the grab dredgers working around the clock. The next hopper dredger campaign, planned for spring 2024, will allow the Port of Ravenna to already welcome the next generation of cruise liners and containerships amongst other vessels.

Boosting container handling capacity in Colombo, Sri Lanka

In a major project in Asia and highlighting the wide-scale economic benefits of its port development work, DEME has successfully performed dredging and reclamation works for the extension of the Western Container Terminal (WCT) in Colombo on behalf of Adani Ports, India's largest private port operator.

Finished well ahead of schedule and carried out by 'Bonny River', this capital dredging project boosts Colombo Port's container handling capacity substantially and further consolidates Sri Lanka's strategic advantage of being located along one of the world's busiest global transhipment routes.

a quay a depth of 20 m, a large-scale mobilisation and

Following the works, WCT now has length of 1,400 m and making it suitable for ultra-large container carriers. Operations began in September 2022 after wrapped up in May 2023. Approximately 9 million m3 ofreclaimed material was dredged from an offshore sand source.

Here, DEME's experienced international project team and modern fleet, as well as its expertise in logistics management, were fundamental to the smooth running of the project.

Technologically advanced vessels

Being one of DEME's largest hoppers, 'Bonny River' was the ideal size to extract sand offshore and efficiently transport it to the location, which was a considerable distance away and 20 km offshore. 'Bonny River' can reach impressive dredging depths of 74 m and the dual pipe system provides flexibility and redundancy, adding a backup solution if any repairs are needed. The sand encountered in Sri Lanka was very coarse and abrasive, which resulted in the vesselrequiring constant maintenance due to wear and tear, but the team could continue working almost without stopping due to the dual pipe system's efficiency and reduced downtimes.

DEME had to mobilise equipment from several countries, including reclamation and floating lines, as well as specialised dry earthmoving equipment suitable forreclamation works. The dry earthmoving equipment was a particular challenge, but fortunately DEME has close partnerships built up over many years with the specialist suppliers.

When preparing for the foundations of the terminal, DEME performed geophysical surveys to assess the various soil layers and performed geotechnical surveys such as seabed Cone Penetration Tests (CPTs), and by combining data from the different sources DEME created a detailed 3D model. This also highlighted the levels of unsuitable material (e.g. silt, 'soft material') that had to be dredged and relocated in a dedicated area outside the port.

With safety a priority, the team also performed drone surveys, allowing data to be collected at freshly reclaimed areas, and thus removing the field surveyors' exposure to unnecessary risks. Additionally, it provided faster survey data collection,resulting in a progress survey of the fullreclamation area after the vessel's sand discharge.

Solution-oriented team

In addition to an environmental impact assessment, the project team monitored the water quality and turbidity at the dredging site, within the port, and at the sand winning location.

DEME's team managed to finish the project to a really tight deadline and even ahead of schedule to the full satisfaction of the customer.

Having a proactive and solution-oriented team is undoubtedly the key to success in both Ravenna and Colombo and this allows DEME to foster sustainable collaborations with its customers across the globe.

Fehmarnbelt connects Denmark and Germany with sustainable infrastructure

Efficient and sustainable transport links are vital as the world transitions away from fossil fuels to cleaner energy, and rail transport is certainly one of the greenest ways of transporting people and freight. DEME is playing a key role in contributing to this development through its work at the Fehmarnbelt Fixed Link project.

Heralded as the infrastructure project of the century, and fostering trade and tourism in Northern Europe, the Fehmarnbelt Fixed Link connects Denmark with Germany, and at 18 km, it will be the longest immersed road and rail tunnel in the world.

Fehmarnbelt is set to be one of the most important transport links in the European network of roads and railways and it will vastly improve travel times between Hamburg and Copenhagen and the entire Scandinavian region. The tunnel will shorten car journeys between the German and Danish coasts to just 10 minutes, compared to a 160-km detour via Jutland. In a further boost to sustainability goals, electric freight trains will be deployed.

Bringing decades of expertise in immersed tunnels and large-scale infra marine projects, DEME is a member of the Femern Link Contractors' joint venture, which was awarded the contract in 2016. Following more than four years of preparations, the joint venture officially started the works on 1 January 2021.

Immersed tunnel and offshore expertise

DEME's offshore experience is vital to the smooth running of the project. One of the biggest challenges of the Fehmarnbelt Fixed Link is that it is essentially an offshore project. While most immersed tunnels cross rivers or are land based, this tunnel actually crosses a stretch of open sea and is in the Baltic.

Therefore, the specialist vessels being built for the project have been designed and specifically adapted for offshore conditions. Two new work harbours have also been specially built for the project where the 30 auxiliary vessels can shelterin case of bad weather. All of the construction material, including cement, sand, aggregates, marine rocks and steel rebars, is also brought into the harbours from several destinations across Europe.

2023 is a 'transition year' and marks the completion of the temporary works such as the construction of an enormous production facility with three large halls in Rødby, where the tunnel elements are being constructed. The facilities are partly underwater and connected directly to the harbours to enable the tunnel elements to be floated before they are transported and immersed in the pre-dredged trench.

89 tunnel elements

89 elements will be installed, 79 of which are 217 m long. In addition, in 2023, works started on the access ramp on both sides. 'The Village' was also built which accommodates 1,345 workers. The construction offour customised pontoons also continued. Here DEME's shipbuilding expertise is very much appreciated, with the company having built several pioneering vessels such as the mega cutter suction dredger 'Spartacus' and the floating offshore installation vessels 'Orion' and 'Green Jade'. Due to the challenges offshore, simulations and dynamic modelling tests were carried out to make sure the

pontoons are able to handle the harsh wind and wave conditions experienced in the winter months in the Baltic.

Four customised pontoons

A standout feature of the project is the use of twin "immersion pontoons." These specially designed catamarans can work in tandem and effectively "hook up" the tunnel element,facilitating the offshore transport and immersion operation.

Two additional vessels play crucialroles in the rock installation process. The first, a 130-metre-long Multipurpose Pontoon (MPP), takes care oflaying the gravel bed within the trench designated for the tunnel. It can also precisely install a protective filter layer on the top of the tunnelroof. A similar tool was successfully employed in a prior project, demonstrating its effectiveness. The second vessel, the Protection Layer Pontoon (PLP), comes equipped with two excavators with extended reach. These excavators are specifically designed to install the protective layer ofrock armor that will safeguard the tunnel elements.

A fourth pontoon, the Spreader Pontoon, will spread sand backfill around the tunnel elements..

The sheer scale is mind blowing. Around 30 vessels will be deployed and even now, when the project has not reached its peak, some 700 staff and 2,200 workers are busy working on the project. Safety and sustainability are always at the foundation of any DEME project, and both have been considered right from the design stages. DEME's rigorous safety standards are being deployed which means everyone has 'Stop Work Authority' and adopts the 'Take 5 procedure', which requires taking 5 minutes to assess the

situation for any risks before taking action.

Reducing emissions

Sustainability is a major consideration, and one significant initiative was to use materialfrom the site to build watertight dykes that form the basins,rather than transporting and importing clay from abroad, and this represented an impressive 1.5 million m3 of material.

Additionally, the joint venture has made a considerable effort to reduce CO2, particularly emissions arising from concrete production. Ballast concrete in the tunnel is dry rather than the

usual wet concrete which reduces the carbon footprint substantially. Other sustainable initiatives include using shore powerfor all the vessels, and this is even greener because it is produced from offshore wind. As well as this, the whole production facility (including the six production lines, basins, and gates) will be retained after the project and reused.

After 2.5 years of preparatory works, the team is very pleased to get started on the next major stage of the project with the marine works getting underway this year. For DEME, this is a true legacy project. Not only will the Fehmarnbelt Fixed Link be a feature on Google Earth. Everyone who has worked on it knows they have taken part in a project which is an important step forward in Europe's sustainable ambitions.

Three quarters of the planet's major cities are on the coast. Millions of people are therefore extremely vulnerable to the impact ofrising sea levels. In addition to flooding and more severe storms, extreme weather events such as storm surges are likely, as well as stronger currents and higher tidal differences. All of these factors are ultimately leading to more coastal erosion.

Addressing this global challenge, DEME's innovative coastal protection solutions - both traditional and nature-based - are increasingly vital. Coastal protection has always been part of DEME's extensive portfolio of marine solutions. For decades DEME has been constructing dykes, storm walls and groynes, and executing large beach reclamation and restoration projects, alongside solutions inspired by nature such as replanting mangrove swamps.

However, in 2009 DEME started to take a closerlook at long-term solutions following increasing awareness in Belgium particularly that the country had to adapt to changes caused by sea levelrise. DEME is convinced that nature-based solutions are a valuable additional marine engineering tool.

Three main options were considered. One examined 'giving the land back to the sea', but given the relatively short and highly populated coastline, this was not an option. Another was 'holding the line' – effectively keeping the existing sea protection where it is - and building up beaches, dykes, and flood gates until they are high enough to allow for the rising sea level. But this solution is deemed limited because it is difficult to continually make the sea defences higher and higher.

The third, and optimal solution, is to protect the coastline seawards by creating sand banks offshore and extra dunes onshore through large-scale reclamation and 'dune before the dyke' type solutions.

A major project,funded by the Flemish government with the help of the Blue Cluster, has been underway off the Flemish coast at De Panne: Coastbusters. DEME is a key member of the Coastbusters coastal management project, which aims to take an innovative approach with regards to traditional coastal and river embankment management methods and instead develop pioneering flood defence solutions inspired by nature.

Sustainable reefs inspired by nature

Established in 2017, the Coastbusters concept limits erosion and improves coastal management techniques by the construction of natural biogenic reefs from biobuilder species such as plants, bivalves and worms, which in turn contribute to biodiversity and a healthy, well-balanced ecosystem. In the second phase of the Coastbusters project, the team looked to establish a trial in Belgium with a specific focus on mussels as a pioneering species. Following extensive trials, mussels are considered the best option to kickstart a sustainable reef. During earlier trials, long lines are installed and when the mussels grow to full size, they drop off the lines and create a naturalreef. This has proven to be the most effective way to create a reef, holding the sand in place and preventing erosion.

A new design, called The Mussel Shaker, was introduced. This nature-based solution has sparked quite some interest, with one wind farm developer exploring the potential of introducing the system at a wind farm.

Addressing rising sea levels with innovative coastal protection solutions

Currently, nearly 40% of the global population lives within 100 km of the coast and approximately 10% (representing some 600 million people) live in coastal areas that are less than 10 m above sea level.

Bankbusters in estuarine regions

In another example of using an innovative approach with regards to traditional coastal management methods and pursuing the Coastbusters philosophy, DEME is also part of the Bankbusters consortium. This initiative re-examines traditionalriver embankment management techniques and instead aims to develop nature-based solutions that deploy natural materials rather than traditionalrevetment.

To mitigate the impact of sea levelrise and flood risks in estuarine regions, the Bankbusters consortium is researching and designing an engineered tidal marsh using only natural materials and reusing soft dredged sediments. A trial is underway along the River Scheldt whereby DEME is partnering with the Universities of Ghent and Antwerp. This trial brings together DEME's expert knowledge of handling and treating fine dredged materials with its ecological, technical, and morphological expertise.

Circular approach to coastal protection

Separately, DEME is performing the New Lock Terneuzen (Noordzeesluizen) project in the Netherlands. At 427-m long and 55-m wide, the New Lock is being built in the middle of the existing Terneuzen locks' complex and is generating huge amounts of sand – nearly 2.9 million m3. Part of the dredged sand is being brought to the Belgian coast by DEME where it is used to build up the underwater dunes for shore protection.

This project again demonstrates DEME's focus on the circular economy and how the combination of nature-based solutions, combined with more traditional methods, ensure resilience against climate change for generations to come.

DEME Environmental is a leading provider of innovative solutions for soil remediation, brownfield development, environmental dredging, and sediment treatment.

Backed by a well-established network offixed and mobile treatment facilities across Belgium, the Netherlands, and France, we have been tackling the challenges of polluted soils and waterways for decades.

Segment performance 2023

The Environmental segment saw its orderbook furtherincrease to a level of 355 million euro and accelerated its turnover with a growth of 48% compared to 2022. The topline growth was fuelled by ongoing work on the long-term and complex remediation and high-water protection projects in Belgium (Blue Gate in Antwerp, Oosterweel, Cokerie du Brabant), the Netherlands (GoWA), the UK and Norway. The team finalised the multi-year Condé Pommeroeul project in France and kicked off new large projects in IJburg and Marken in the Netherlands.

DEME's Environmental team continues to set the standard for addressing the

environmental challenges of the future, including PFAS pollution,for which it has developed a pioneering solution. The team also continued to invest and expand the capacity ofits network of fixed and mobile soil treatment centres. EBITDA for 2023 was 51 million euro, with an EBITDA margin of 16.8%, up from 12.1% in 2022. The strong profitability incorporates a non-recurring impact from a settlement on a completed project in the Netherlands. Excluding this impact, the Environmental segment would still demonstrate an improved profitability compared to 2022.

As of 31 December 2023, the orderbook stood at 355 million euro, an increase of

13% compared to 313 million euro a year earlier, mainly driven by new contract wins in Belgium and the Netherlands. Of note is the recent win in Feluy in Belgium where a brownfield site will be remediated and transformed into an industrial estate in collaboration with public and private partners. The segment is actively exploring new, targeted opportunities in Italy and the UK, commencing initial environmental study efforts.

Testimonial Taking the lead in tackling PFAS pollution

PFAS, dubbed 'forever chemicals', are a major pollutant across the planet and DEME is a front runner in developing innovative technologies to help rid the world of this ubiquitous problem. With estimates ranging from 8,000 to 15,000 different types of synthetic per- and polyfluoroalkyl substances, the scale is enormous. PFAS is found in hundreds of everyday items, from cosmetics to non-stick pans, to firefighting foam.

In a recent Europe-wide investigation, Le Monde and the Forever Pollution Project identified over 2,100 hotspots that are likely to have such high levels of PFAS contamination that it could be hazardous to health.

Flagged up initially in the Netherlands, DEME's environmental experts have already been addressing the remediation of with PFAS polluted soilfor several years. This has led to the invention of a pioneering treatment method known as the DEME Hybrid Soil Washing Process. This is essentially a combination of a soil washing process and a water purification process.

DEME has conducted extensive trials exploring solutions for cleaning PFAScontaining soil. For example, in 2020, in collaboration with engineering firm Tauw, the company introduced a solution to the Dutch market for the cost-efficient and sustainable cleaning of PFAS contaminated soil.

After many years ofrefining the technique, PFAS can now be removed from contaminated soil. The soil washing method effectively transfers the PFAS to water and then the wateris immediately purified by means of active carbon filters. The active carbon is hence heated to 1,000 degrees Celsius under high pressure and any PFAS remaining in the filters is destroyed and converted into harmless products.

The Environmental team carried out large-scale tests in 2021 on 30,000 tonnes of polluted materialfrom a former car manufacturing factory in Antwerp. The tests were successful and closely monitored by OVAM, the Flemish Waste and Sustainable Material Management authority.

300,000 tonnes per year

The trials then led to an investment decision, together with its partner Mourik, to adapt its soilrecycling centre in the port of Antwerp for PFAS treatment. A second soilrecycling centre in Belgium has also been equipped for PFAS and DEME has built a mobile treatment facility specifically for PFAS that handles 100 tonnes an hour. With the investment in Antwerp alone DEME and Mourik will be able to clean 300,000 tonnes of PFAS contaminated soil per year.

Currently, the DEME Environmental team is cleaning PFAS pollutants from the Oosterweel Link project in Belgium which will complete the Antwerp Ring Road. Without DEME's innovative solution, work on the project could not have continued. Approximately, 500,000 tonnes of soil are expected to be treated during the huge infrastructure project.

Recently DEME has been awarded a contract to bring its unique cleaning solution to one of the largest airports in Europe. DEME will be cleaning and treating PFAS polluted soils at Amsterdam Airport Schiphol. The new installation is expected to be ready in the second half of 2024.

Separately, DEME is looking to establish a fixed PFAS cleaning facility in Den Helderin the Netherlands. As well as treating polluted soils, DEME is exploring the potential of cleaning PFAS from groundwater and adapting its techniques to all types of soil containing PFAS contamination.

With increasing interest in Europe and from many of the large PFAS producers and chemical companies, DEME is sure that it is the 'go to' competent company to address this global challenge.

Nature cleaning nature

DEME Environmental and C-Biotech, a subsidiary of the Belgian Cordeel Group, have joined forces to launch Fytolutions, an initiative that harnesses the remarkable cleansing power ofindustrial hemp to address PFAS pollution. The hemp plants are grown on PFAS-contaminated sites, effectively removing these hazardous chemicals from the soil.

The joint venture's initialfocus will be on providing phytoremediation services within Belgium and Luxembourg. DEME Environmental's team of experts will identify PFAS-polluted sites, and Fytolutions will work with them to design a tailored remediation solution that combines phytoremediation with traditionalremediation techniques when necessary.

Innovative solutions for dyke reinforcement in the face of climate change

With extreme weather events becoming more common and sea levels rising, DEME is at the centre of efforts to build resilient infrastructure. A prime example is the company's involvement in major dyke reinforcement projects in the Netherlands.

Being a low-lying country, with more than a quarter of the country below sea level, the Netherlands has embarked on a major National Flood Protection Programme. The original plan called for the reinforcement of 1,500 km of dykes, but a revised assessment in 2023 has increased the estimated length to 2,000 km.

One vitally important reinforcement project, awarded to DEME in a consortium (the Lek Ensemble), together with Heijmans and GMB, is 'Sterke Lekdijk'. DEME is also teaming up with these partners on the Gorinchem-Waardenburg (GoWa) project, another major dyke reinforcement programme that is part of the national plan.

The river Lek dyke protects a large part of central and western Netherlands against flooding – around a million people - and if there is a breach of this dyke it could endanger many of the biggest cities in the country including Amsterdam, Rotterdam and The Hague.

Protecting cities in the Netherlands

Awarded by the Stichtse Rijnlanden Water Board (HDSR), the Sterke Lekdijk project involves strengthening a 55-km stretch of the dyke. The project has been split into six scopes and DEME and its partners have been awarded two of them: Wijk bij Duurstede - Amerongen and the second route between Jaarsveld – Klaphek. The consortium's solution must last for at least 50 years, and a crucial part of the project is a focus on zero emissions as the Netherlands works towards achieving the clean energy transition.

Unusually, HDSR tendered the project using a so-called 'Innovation Partnership' which means all the parties must design the project whilst taking sustainability, innovation and cooperation into account. In practice this means that the Lek Ensemble consortium will collaborate closely with its customer but also with other contractors on all six sections of the project during this stage.

The new contract form underscores the need to work together as a source of inspiration forinnovation for the project. Resulting innovations will then immediately be introduced during all six sections.

Focus on innovation

The Lek Ensemble is exploring innovative dyke reinforcement methods using Soseal, a saline solution that replaces expensive sheet piles. This impermeable barrieris introduced via pipelines and injections, eliminating the need for digging and sheet pile walls, preserving the dyke's integrity. Anotherinnovation involves bentonite mats that expand upon contact with water, forming a waterprooflayer and reducing the need forlarge clay quantities.

A vitally important part of the tender was that the contractors must consider the use of zero emission equipment wherever possible. Therefore, with sustainability top of the agenda, the Lek Ensemble is developing the equipment, and it also

organised the 'Emission-free network infra' (ENI)foundation during the tender phase. ENI brings all parties together, including competitors, so they can accelerate the development of emission-free equipment for the entire Netherlands Flood Protection Programme by sharing their knowledge and experience. Ultimately, the entire industry can benefit from the shared innovations introduced during the Lekdijk project.

Members of ENI include Volvo, Hyundai, Rijkswaterstaat (the Directorate-General for Public Works and Water Management) and TNO amongst others. This foundation is already expecting to hit its zero target in 2026 rather than 2030.

Investing in emission-free equipment

However, the focus on zero emissions presented a challenge originally when the contract was awarded in 2020. At that time, there were no manufacturers of this equipment. So again, DEME's experts and their partners had to put their heads

together to come up with a sustainable solution. Traditional equipment using diesel engines has been purchased and these are being converted into electrically driven machinery. Currently, two excavators are already working fully emission-free, and these will be joined by two loaders. As well as this, the partners will introduce three fully electric cranes on the Lekdijk project.

Sustainable solutions

Sustainability is considered throughout the project, but it is also considered in a much wider context for DEME's own sustainable goals too. An initiative called 'Working on Zip Zero' has been launched whereby DEME aims to attract the new generation of hydraulic engineers and indeed, anyone who is keen to play a role in achieving a sustainable planet. The Sterke Lekdijk project is a fantastic example of sustainability in action on many fronts.

The Lek Ensemble team is working together, closely with the customer and its partners, to find sustainable solutions which will benefit the planet and ensure that the Netherlands is secure in the knowledge that the Lekdijk is safe and the cities surrounding it,for the decades to come.

DEME Concessions oversees a diverse portfolio of concessions across offshore wind, infrastructure, green hydrogen, and mineral harvesting.

Unlike DEME's contracting work, DEME Concessions actively invests in, develops, constructs, and operates these concessions,fostering long-term partnerships, generating recurring revenue streams, and creating sustainable value for shareholders.

Building on its success in traditional markets, DEME strategically expanded into technically challenging and less mature sectors like offshore energy, green hydrogen, and responsible deepsea mineral harvesting. This strategic move has already yielded significant achievements, including the 2 GW ScotWind concession.

DEME Concessions oversees DEME's development activities in offshore wind, marine infrastructure, green hydrogen and mineral harvesting. In 2023 the concessions activities delivered a net result of 37 million euro compared to 9 million euro in 2022, partly driven by higher wind production and higher electricity prices. The Concessions segment has economic ownership of 144 MW of wind energy from offshore wind concessions in operation, generating recurring income, while building a pipeline that already includes more than 2 GW in Scotland, in which DEME holds a 42.5% participation. As well as this, it is exploring and developing additional opportunities.

For Dredging & infra, the Concessions segment is forging ahead with the Blankenburg Connection in the

Netherlands, Port-La Nouvelle in France and further expanding in Port of Duqm in Oman. DEME continues to explore new opportunities for ports and other concessions, mainly in Europe and Latin America. In this context, a consortium consisting of DEME and QTerminals W.L.L. signed a preliminary agreement in 2023 for the financing, construction, and operation of a new deepwater terminal for the port of Swinoujscie in Poland. DEME Concessions remains on track to be amongst the first in the world to produce green hydrogen and green ammonia. At its flagship green hydrogen project HYPORT Duqm in Oman, DEME and its development partner OQ Alternative Energy signed a Project Development Agreement with the government in Oman. Additionally other locations are being explored to deploy the same HYPORT technological concept.

The Concessions segment also continued to work on the Global Sea Mineral Resources (GSR) initiative, which marked a decade of deep ocean exploration and innovation in 2023. GSR is helping to tackle the scarcity of the planet's resources in the most responsible way and is continuing its research into the possibility of collecting metal-rich, polymetallic nodules from the deep ocean floor. In February 2023, GSR announced a strategic cooperation with Transocean Ltd (NYSE: RIG) whereby Transocean contributed an ultra-deepwater drilling vessel and a cash investment. The ISA(1) council indicated in July 2023 that it is aiming for the adoption of a regulatory framework in 2025.

Developing a hub for the green energy transition in Port-La Nouvelle

Port-La Nouvelle perfectly embodies DEME's ambition to address long-term global challenges and to pursue its strategy of sustainable growth.

DEME Concessions is the initiator and an indirect shareholder of the SEMOP (a single-purpose public private partnership in France) that has been awarded a 40-year construction, operation, management and development concession for the port of Port-La Nouvelle. The concession was signed and the SEMOP has been operating the port since 1 May 2021. This port project highlights both DEME's efforts to play a vital role in the energy transition (through its work developing the offshore wind and green hydrogen sectors) and its drive to support the growth in world trade and increasing globalisation with its dredging and reclamation activities.

As well as DEME Concessions being a member of the SEMOP, DEME's dredging and infrastructure teams are involved in the construction of the new hub. DEME is performing the Engineering, Procurement and Construction contract at the port.

Key role in energy transition

The SEMOP is developing Port-La Nouvelle as a sustainable green port that contributes to the energy transition. A key element will see the port become a dedicated logistics hub forfloating offshore wind projects, and it is worth noting that it is the only commercial development in the Western Mediterranean for this new industry. Being one of the best areas for wind resources in the Mediterranean, the port is idealfor either assembly or as a maintenance base.

Furthermore, the French port has the ambition to become a green hydrogen hub for both imports into France and Europe and for the distribution and production within the port as well.

Crucially, the SEMOP is repositioning Port-La Nouvelle as the leading terminal for bulk goods and general cargo in the Mediterranean by providing accessibility forlarger vessels and dedicated handling facilities. A 80-ha logistics activity zone is also being developed.

Uniquely, Port-La Nouvelle is the first comprehensive port in France jointly managed by private companies and public entities, offering a new public/private model of governance for the country. The SEMOP brings together public players - the Region of Occitania and Banque des Territoires (Caisse des Dépôts)- and Nou Vela, a private shareholder group led by DEME Concessions and including Euroports, a leading international stevedoring company, EPICO, a fund managed by the Flemish Investment Fund, QAIR, an independent power producer ofrenewable electricity and the Aude Chamber of Commerce and Industry.

With over 140 ha available, Port-La Nouvelle will be the only port between Marseilles and Barcelona with such a large amount of land offering deep water access. It is also the only port directly connected to such a big hinterland, serving as a gateway to Toulouse and other important economic and agricultural centres.

Work to extend the port actually began in 2019 under the management of the regional authority, with the construction of a 2.5 km northern dyke, the extension of an existing southern dyke by more than 600 m, and the construction of a 250-m heavy load quay. The SEMOP continued these extension works with the construction of a large dedicated floating offshore wind terminal (40-ha land and adding 300 m heavy load quay), a new liquid terminal and a bulk terminal in a basin dredged to a depth of 15.9 m to accommodate large seagoing ships.

The port is immediately adjacent to the national rail grid and the port's terminals are directly connected to the grid. Additionally, the port will further expand and enhance its rail network by 2026 to provide optimal rail modality.

Hub for floating offshore wind

The new strengthened quay is next to a 7-ha area ofreclaimed land which is where two pilot floating offshore wind projects are based. EolMed and EFGL both have a capacity of 30 MW. Alongside this site, the new, large-scale renewable marine energy terminal specifically forfloating wind farms is under construction. Firmly on track, over 40% of the construction works are now completed and will be ready to be fully commissioned in 2025.

The liquid bulk jetty is also under construction and will provide state-ofthe-art facilities to Total and Dyneff.

Green hydrogen terminal

Also, the SEMOP is planning the development of an extensive green hydrogen import terminal serving Southern Europe up to Germany. The SEMOP has already inked an agreement with Hyd'Occ, which started construction of a 5-ha site for the production of green hydrogen locally.

Port-La Nouvelle is a showcase for many of DEME's activities and its ambitions to help find solutions for global challenges. DEME is delighted to see the boost to the local economy and to see the port welcomes its first customers.

Green hydrogen is particularly effective when it can be produced at locations where solar and wind energy resources are powerful and abundantly available.

As the renewable electricity is captured in a molecule, green hydrogen offers solutions to use cases where direct electrification is more challenging, particularly in existing hard-to-abate industries (petrochemical,fertilisers, steel) and new hard-to-electrify mobility cases (marine transport, aviation, …). Furthermore,future use cases include long-term and large-scale storage, crucial for balancing supply and demand on busy, congested energy grids. While there is still a lot of debate about just how much green hydrogen capacity will be needed, there is little debate about the fact it is needed.

With its renowned pioneering mentality, DEME has already been actively exploring the vast potential of this energy vector for many years. The company is taking a careful, step-by-step approach, and recognises that developing this sectoris hugely ambitious, given the fact that it is starting from zero.

Supportive shareholders

However, the DEME team is undaunted by this immense task having taken the first steps into new, unproven markets before such as the offshore wind sector. The commitment to green hydrogen fits perfectly with DEME's track record of entering groundbreaking, undeveloped sectors characterised by a combination of complex technical, commercial and engineering challenges. Although this is a new 'industry', it is not a new approach for the company.

Complementary to existing business

Setting up green hydrogen projects is an extension and complementary to DEME's renewables and port development experience. On the one hand, DEME has vast experience in developing renewable generation assets, which are essential to any green hydrogen production project. On the other hand, DEME's knowledge in and around ports, connecting global clusters, is important as these molecules will primarily be shipped between supply and demand hubs.

In this context, DEME took the strategic decision to start building up its green hydrogen project development expertise in 2018. This recently culminated in 2023, when DEME Concessions established a dedicated green energy initiative where all ofits green hydrogen interests are brought together.

The DEME green hydrogen development is growing rapidly its project portfolio (including its flagship HYPORT Duqm

project in Oman globally, and other technology initiatives such as HYVE), where DEME is participating in a consortium to develop the next generation of electrolysers. The HYVE consortium includes renowned research centres Imec and VITO, together with industrial pioneers Bekaert and John Cockerill. Additionally, DEME Hyport Energy accommodates an impressive expert engineering team and has been building a proprietary digital twin modelfor simulating the competitiveness of entire green hydrogen value chains.

During 2023, several key milestones were also realised at DEME's flagship project HYPORT Duqm, which is amongst the leading projects in the world that will produce green hydrogen and green ammonia at utility scale.

HYPORT Duqm is being developed on an area of 150 km² within the Special Economic Zone at Duqm. The production of green hydrogen to green ammonia is powered by both wind and solar energy, with a combined capacity of around 1.3 GW under Phase 1 and potentially more than 2.7 GW on completion of Phase 2. The first phase of the project, which is part of Oman's ambitious green energy targets (Vision 2040), is set to produce approximately 330,000 tonnes of green ammonia.

A leading role in the growing green hydrogen sector

With a pressing need to accelerate the clean energy transition and move away from the use of fossil fuels, DEME is already establishing itself as a front runner in the green hydrogen sector, just as it did in the offshore wind industry more than 20 years ago. It has become abundantly clear in recent years, that green hydrogen, which is produced from electrolysis using renewable electricity, is now seen as an important contributing 'puzzle piece' in the energy transition, complementary to direct electrification from renewable energy sources. A robust green hydrogen ecosystem

In June 2023, DEME and its development partner OQ, the leading global integrated energy group in Oman, signed a Project Development Agreement with Hydrom, which represents Oman's national interest in green hydrogen and is regulated by the Ministry of Energy and Minerals. With this agreement in place, HYPORT Duqm can kick-off the next stage of project development in 2024, including more detailed engineering following an extensive pre-FEED campaign.

Duqm's strategic location and abundant renewable resources will enable DEME to establish a robust green hydrogen ecosystem. The Project Development Agreement provides DEME the right to develop and operate the project for 47 years and the associated timelines for construction and operation acknowledge HYPORT Duqm's leading position, with a commitment to become the first operational, large-scale green hydrogen project in Oman. Furthermore, the agreement locks in HYPORT Duqm's concept design, whereby the renewable energy will be transmitted from the generation site via a high-voltage transmission line to its industrial site near the Port of Duqm, where the electricity will be used for electrolysis and follow-on ammonia production.

HYPORT concept extended to other countries

In other strategic locations, DEME is also working with local partners in progressing utility-scale green hydrogen/ammonia projects, and more possibilities are being explored globally. The HYPORT concept is proving attractive to de-risk hydrogen

projects and to attract investors and will be replicated, optimised, and adapted to the project-specific conditions.

DEME's presence and track record globally means the company can tap into its vast working experience and network around the globe, performing large-scale dredging, infrastructure, offshore and environmental projects over the last decades. And the most valuable asset – DEME's ingenious people – is vital when developing a new industry. In contrast to other players in the market, DEME believes it offers a different

proposition because it has taken the time to understand the value chain and it is taking a realistic, carefully paced approach in de-risking all aspects of such a complex development, which takes patience. It can only do this because it has long-term orientated shareholders and a strong team of highly skilled professionals. Green hydrogen highlights its capability to be a developer, think as a contractor, act as an operator and vitally, its ability to attract capital. DEME can deliver long-term, large-scale projects and ones that are breaking new frontiers. The company has proven this once again.

Project showcase Addressing the global shortage of critical minerals

Global Sea Mineral Resources (GSR) embodies DEME's pioneering spirit and drive to find sustainable solutions. With demand for critical minerals set to increase dramatically in the decades to come due to population growth, increased urbanisation and the clean energy transition, GSR is addressing this global challenge and plans to play an important role in the development of a responsible deep seabed minerals sector.

There is growing recognition that critical minerals are key for a successful decarbonised energy transition and the International Energy Agency has reported that society will need six times more minerals by 2040 to become a net-zero society in 2050. Critical minerals, such as nickel, cobalt, copper and manganese – all found in polymetallic nodules on the deep ocean floor – are seen as crucial ingredients for a low-carbon future.

Marine minerals are emerging as a potential source of these critical minerals and they could expand diversity of supply to help meet growing demand. But this is only if deep seabed minerals can be proven to be one of the more environmentally and socially responsible options for obtaining the minerals society needs.

10 years of deep ocean exploration

Celebrating its 10-year anniversary and a decade of deep ocean exploration, research and innovation in January 2023, GSR is carefully exploring the potential of marine minerals, including developing deep-sea nodule collection technology, and by working together with the scientific community.

Ten years ago, DEME signed an exploration contract with the ISA. Under the contract, GSR has exclusive rights for polymetallic nodule exploration over nearly 75,000 km² of the seabed in the eastern part of the Clarion Clipperton Fracture Zone of the Pacific Ocean.

Seven offshore expeditions

Many milestones have been achieved during this pioneering decade including seven offshore expeditions totalling 266 days at sea, the mapping of the entire Clarion Clipperton Fracture Zone contract area,five and a half years of oceanographic data collection and more than one million photographs of the deep seabed.

One of the world's front runners in the development of polymetallic nodule collection technology, GSR has so far successfully conducted two ultra-deep water technology trials at a depth of 4,500 m.

During this period, 27 scientific publications have been published in peer-reviewed journals. According to the scientific literature, minerals from the deep sea could be delivered with a 40% reduction in carbon footprint, and with less waste, when compared to landbased mining for the same minerals.

Additionally, in 2023 the first independent scientific report of GSR's 'Patania II' (pre-prototype collector) expedition was published, outlining the technical achievements and scientific learnings gained from technology trials conducted in two ISA contract areas. The report's author, Dr. Thomas Peacock, is a professor at the Massachusetts Institute of Technology (MIT). During the trials he was on board the GSR-chartered vessel and led a team of MIT-scientists to validate and further improve sediment plume models.

Since 2018, GSR has collaborated with the MiningImpact2 (MI2) consortium, representing scientists from 29 European institutes and nine different countries. MI2 scientists also independently monitored the technology trials. Commenting on both trials, Professor Peacock said: "This collaboration between industry and independent scientists resulted in unprecedented and transparent monitoring ofrealistic seabed nodule collector technology on the abyssal plains of the Clarion Clipperton Zone."

Transocean alliance

Highlighting increasing worldwide interest in the sector, Transocean, a global leaderin the offshore drilling industry and well known forits ultra-deepwater expertise, teamed up with GSR in early 2023. Transocean decided to invest in the company by contributing an ultradeepwater drilling vessel, a cash investment and additional engineering capacity.

This powerful strategic alliance will both strengthen GSR's subsea experience and in turn contribute to its leadership position in the deep seabed minerals sector. Under the cooperation, Transocean gains a minority stake in GSR and is entitled to appoint a member of the Board of Directors of GSR.

Transocean's drilling vessel, the 'Ocean Rig Olympia' will be converted for a system integration test. The system integration test is scheduled for 2027 and will entail a trial of a full-scale seafloor nodule collector and riser to lift the nodules to the surface vessel. This trial is deemed a vital step in the technology development as GSR continues to responsibly explore the feasibility of commercial operations.

DEME's four most material themes

DEME considers the ESG topics in the high-high quadrant of the Materiality Matrix as its most material topics.

Greenhouse Gas Emissions

In line with our ambition to achieve climate-neutral operations by 2050 (Scope 1 & 2), we are aiming to be at the forefront of the industry when it comes to integrating climate proof technology and excellence in energy performance into our operations.

We are aligned with the 2023 International Maritime Organisation's GHG Strategy which envisages both a reduction in carbon intensity, as an average across international shipping, by at least 40% by 2030 versus the base year 2008, and to peak GHG emissions from international shipping as soon as possible and to reach net-zero GHG emissions by or around 2050. This is whilst pursuing efforts towards phasing them out consistent with the long-term temperature goal set out in Article 2 of the Paris Agreement. In addition, we intend to reduce GHG emissions across our entire project value chains (Scope 3).

In preparing the consolidated financial statements, the Group has considered the potential impact of climate related risks which cover both transition risks and physicalrisks (Chapter 06).

DEME follows the Greenhouse Gas Protocol and reports its GHG emissions according to three scopes (Scope 1, 2 & 3). DEME's total worldwide carbon footprint includes carbon dioxide (CO₂), nitrous oxide (N₂O) and methane (CH₄).

DEME's worldwide greenhouse gas emissions Scope 1 and 2, based on the actual data collection, relates to 95% of our vessels. The remaining portion of Scope 1 and 2 is shared between machinery and equipment, lease cars and buildings.

In 2023, total Scope 1 and 2 greenhouse gas emissions amounted to 734 kt CO₂e. The amount of DEME's annual total global greenhouse gas emissions is largely dependent on the type of projects and the vessel occupancy.

The increase in total greenhouse gas emissions in Scope 1 and 2 compared to 2022 is caused by a slightly higher occupation of our Offshore Fleet and the deployment of a number of cutter suction dredgers in more energy-intensive projects.

Focus on highly material topics

The focus of DEME's sustainability priorities lays with its most material topics, including Greenhouse Gas Emissions, Energy Efficiency, Safety, Responsible Business Conduct and Sustainable Innovation.

Reduction of GHG emissions in our project supply chains

Within the framework of the ISO 50001, five main significant energy users (SEUs) have been identified: vessels, buildings, machinery and equipment, transport of people and purchase of goods and services.

This framework streamlines our energy management by allowing us to seamlessly integrate it with greenhouse gas emission management.

Here is an overview of all the SEUs with their corresponding targets. The following pages willfurther clarify how we are working to improve our energy efficiency and reduce GHG emissions within Scope 1, 2 and 3.

We have set two targets related to greenhouse gas emission reduction, specifically targeting the emissions from the vessels within our fleet. These were set to further increase energy efficiency, to reduce greenhouse gas emissions intensity, and to be able to make the switch to the use of future zero carbon fuels in the long run.

Key Messages

• 1. DEME aims to achieve climate neutral operations by 2050 and has set an intermediate GHG intensity target to reduce 40% ofits fleet GHG emissions per dredged m3 orinstalled MW by 2030 versus the base year 2008.
• 1. DEME's ambition and targets are set in line with the 2023 IMO GHG strategy.
• 1. By the end of 2022, we have already achieved a reduction in GHG intensity of 26.6% compared to 2008. Another 13.4% needs to be gained by 2030. The methodology, as well as the data, process and fleet GHG intensity calculations based on the defined methodology has been verified for the first time by an independent third-party, Lloyds Register, in May 2023.
• 1. To further work towards our 2030 target, we are focusing on three strategies: operational efficiency, technical efficiency and fuel shift.
• 1. The amount of DEME's annual total global GHG emissions is largely dependent on the type of projects and the vessel occupancy. In the mid- and long-term, a reduction in absolute GHG emissions will mainly rely on a furtherfuel shift towards net zero carbon fuels. The first pilot tests on the use of these future fuels are being set up.

DEME's vessel GHG emissoins roadmap for the fleet

01. Operational efficiency

We are continuing with the modernisation and upscaling of ourfleet with the conversion of a bulk carrierinto a DP2 fallpipe vessel. The payload of the new FPV is more than double that of DEME's existing largest vessel. On projects with long sailing distances, this not only brings great economies of scale but also fewer trips are required,resulting in substantialfuel savings. Furthermore, the long and slender hull and highly efficient propulsion make 'Yellowstone' a champion ofreduced fuel consumption per km.

02. Technical efficiency

The vessel will have a hybrid power plant, consisting of a smart power management system and a battery pack, which stands by as a power and energy reserve, allowing the FPV to keep only well loaded engines running, making it possible to achieve 10-15% in fuel savings, especially in DP mode. As well as this, it will be equipped with a waste heat recovery system.

'Yellowstone' will be the first vessel in the fleet prepared for(green) methanol. The first pilots willrun during the course of 2024.

We have a three-pronged strategy in place to reduce the GHG emissions from our fleet:

01.

Operational efficiency Increasing productivity while reducing energy consumption

Throughout the years, we have been focusing on improving the operational efficiency and productivity of ourfleet, resulting in the reduction of our GHG emissions. This reduction can be achieved by modernising and upscaling ourfleet, improving our working methods, and implementing process improvements.

02. Technical efficiency

Delivering more energy on board with less fuel

We continuously strive to increase our technical energy efficiency across the fleet, and thus at the same time,reduce emissions by implementing different kinds of efficiency measures. These include waste heat recovery systems, which convert heat from the exhaust gases to electrical energy, the use offly wheels and battery packs, as well as measures to boost propulsion efficiency such as combinator curves.

03. Fuel shift Using less GHG intensive fuel types

Short and medium-term (low carbon fuels)

Low carbon fuels combine the fuels for which the CO₂ emissions are lower compared to conventionalfuel (marine gas oil). This category includes fuels such as LNG and blended biofuels. By incorporating state-of-the-art, dual fuel technology in our vessels, they are able to run on both LNG in gas mode and conventionalfossilfuels in diesel mode. From an emissions perspective, the concept is that they can readily access the use of a cleanerfuel with the option to fall back on conventionalfossil fuels if alternatives are not available.

Alongside the use of LNG, our vessels can also run on biofuels or a mixture of a fossilfuel with a biofuel, both resulting in a net reduction of our CO₂ and GHG emissions. Biodiesel and biomethane (BioLNG) can be used as a 'drop-in'fuel and on board of vessels currently running on LNG without any technical modifications for storage, handling and combustion.

Best practice

Demonstrating our three strategies on 'Yellowstone'

Medium and long-term (future fuels, zero carbon fuels)

DEME is a keen enthusiast about the potential offuture fuels. That is why we are setting up first pilots to gain experience with these future fuels. In 2024 green methanol will be tested on the 'Yellowstone' and green ammonia on the 'Apollo'.

In 2023, we exceeded our target to consume at least 8% oflow carbon fuels compared to the total amount offuels (energy based).

We are currently working to increase energy efficiency and investing in new sustainable technologies to have a climate-neutral HQ by 2025 and are halfway through the transformation.

The electrification of construction equipment and the use of hydrogen gives the construction sector more and more opportunities to move towards zero emissions, yet there is still no solution for remote locations using energy-intensive construction equipment, and these locations are usually exactly where DEME is working.

1. Buildings

Green offices and creating climate-neutral headquarters by 2025

1. Machinery and equipment Gradually moving to zero-emission machinery and equipment

Best practice Sustainable DEME campus

The DEME Campus is halfway through its transformation into a modern, attractive, sustainable and energy-neutral head office. The DEME Labs and new offices have been fitted with heat pumps and fully electrified heating systems as part of our multi-year plan to gradually shift from fossilfuel heating to the use of green electricity.

During construction and renovation, we have also focused on the design and insulation in order to reduce the heating and cooling demand. In addition, solar panels have been fitted on the roof of the DEME Labs in Q1 2024.

In 2024 we willfurtherfocus on phasing out the remaining diesel consumption: — Demolishing the older buildings representing 50% of the diesel consumption for heating at the campus

— Extending the cold-heat networks for the offices

— Equip the warehouses with heat pumps and radiant panels to phase out the remaining diesel used for heating

Best practice Electric machinery and equipment

In the Netherlands, DEME Environmental operates electric machinery and equipment to achieve a zero-emission work environment. In 2023 the electric excavator Hyundai HX260 arrived and besides this, multiple investments have been made. A hydraulic long reach excavator Doosan 355LC 14mtr and a Doosan DL280 Wheel Loader will be delivered in Q1 2024. Also, in 2023, DEME Environmental has ordered a small electric wheelloader(Volvo L25).

Progress GHG emissions reduction at Headquarters

kgCO2e/GJ energy used

The transport of people at DEME includes business flights, train travel and our car fleet. We aim to reduce emissions related to business travel, increase green mobility in the Benelux and gather insight into our car fleet worldwide.

04. Transport of people Electrification of car fleet progressing swiftly

Best practice Electrification of our car fleet

— a shift in orders towards fully electric vehicles

— a further decline in the number of petrol and diesel

cards ordered, which decreased from 16% to 10%

As the composition of our carfleet has significantly changed, this also has an impact on the GHG emissions (Scope 1) related to the transport of our people.

Looking at the number of electric vehicles (EV) compared to 2022, there was an increase of 12%,resulting in a significant drop in the average CO2 emissions of our carfleet to 70 gCO2/km, bringing us one step

closer to achieving our target of 65gCO2/km by 2025 in the Benelux. In addition to that, the number of ordered vehicles shows that we will be able to achieve our target within the foreseen timeframe.

Finally, in order to encourage commuting by bicycle we launched a DEME Bike Lease programme in 2023, becoming effective in Q1 2024.

Progress on the amount of grams CO2 emissions per kilometre for our lease cars in the Benelux

Overview lease cars ordered 2022 vs 2023

g CO2/km

One of the main energy consumers in the project supply chain is the purchase of goods & services. We aim to reduce GHG emissions across our entire project value chain. This includes exchanging energy and emissions performance data. We are determined to gain further insights into our most significant emissions categories and to set dedicated targets and actions based on an analysis of our Scope 3 emissions and related Life Cycle Assessments.

05. Purchase of goods & services Reporting on the significant emissions in our value chain

Actions

We developed a vision on sustainable procurement, which entails an alignment of the DEME procurement strategy with our corporate sustainability agenda,focusing on our most material topics of which GHG emissions and energy efficiency are two.

In 2023 we started engaging with both our external stakeholders (suppliers), by means of a pilot with a supplier assessment tool as a potential solution for procuring in a more sustainable way and pushing our suppliers to do better, and ourinternal stakeholders (procurement employees) by informing them about our sustainability strategy, objectives and next steps in the pilot phase. The sustainable procurement strategy which is being developed is aligned with the ISO 20400 for Sustainable Procurement.

We managed to onboard 110 suppliers which covers 35% of the DEME procurement spend in 2022.

In 2024 we will determine the significant Scope 3 categories and will set out a detailed and phased plan to calculate our worldwide Scope 3 emissions, including the purchase of goods & services. Looking at ourinternal procurement taxonomy and based on our spend analysis, we estimate that the majority of Scope 3 emissions will come from: — purchase of goods & services

• — upstream fuel- and
• energy-related activities — transport activities
• (Up- and downstream road and water transport) — business travel

Best practice

Low-carbon grouting material

On the Vineyard Wind 1 project, a different grouting material (GUL) was used for the TP installation that has a smaller carbon footprint because of the way it is produced. The GUL grout is a cement material containing less clinker,reducing the CO₂ emissions by 5-10%. Besides this, the grouting material was locally sourced in Canada, which eliminated the transport from Europe to the US. This resulted in a reduction of approximately 170 tonnes of CO2.

Safety

DEME works day in and day out on its safety performance and continuous improvement. We devote a lot of attention to what could possibly go wrong, and certainly to what goes right.

Targets

— The achievement of eight safety indicators reflecting DEME's Safety Performance.

Actions

• — Our annual communication plan kicked off with a campaign encouraging our people to proactively inspect theirlife jackets,framing it as a New Year's resolution for safety.
• — Within DEME, we actively incorporate key elements of our Safety DNA to make a meaningful difference. It is easy to say safety is in our DNA, but what does it really mean? In our opinion, it is all about caring and sharing, that's why DEME encourages its employees to take care of each other and share all available data and knowhow regarding operationalrisk management.
• — Unfortunately, in the first half of 2023, there was a notable increase in Lost Time Incidents (LTIs), demanding an immediate callfor action. Consequently, last year's Safety Week focused on assessing High Potentials (HIPO) and LTIs. Data and near-misses were analysed to identify root causes and potential improvements. DEME employees directly involved shared their experiences, focusing on prevention through better work preparation and communication. Safety videos on various topics spread awareness during toolbox talks,reaching thousands of participants. The Safety Week resulted in numerous inspiring best practice 'Safety Success Stories' and these are being shared throughout the company.
• — Leading up to the Safety Moment Day, nearly 140 projects, vessels, and sites contributed 269 'Safety Success Stories'. These stories highlight achievements and best practices, offering inspiration and identifying areas forimprovement. One notable example involves the collaborative effort between the crew and the Safety by Design-team in designing and constructing a roller conveyor system for safe load transportation through watertight doors.
• — DEME chose several excellent 'Success Stories' to share during the annual Safety Moment Day. Safe access, work preparation, efficient engineering, working at height, mooring and open manholes were just some of the topics highlighted.

Safety Thermometer

Targets

- — To ensure uptake of sustainability as an integral part of every challenge in each innovation campaign.

• of every idea orinitiative during the development phase.

— To make sure sustainability is always part of the evaluation criteria

Actions

— We completed allfour stages of'DEMEx'- DEME's most ambitious innovation campaign. A customised megatrends map was used to create 10 future planets, all of which included sustainability challenges. These planets were used to create a multitude of promising future ventures for DEME of which nine were selected for a six-month incubation period in 2023. From these nine venture concepts, the Innovation Board selected three to advance to the final DEMEx investment phase. It's interesting to note that all of the final ventures are linked to global sustainability challenges (renewable energy,flood protection and ecology/circularity). — We continued developing and implementing the most promising nine initiatives from our'Diver' innovation campaign 2020. One of the ideas being accelerated is the increasing use of zero-emission equipment. — In 2023, we performed 12 'ad hoc' AViSO innovation workshops. AViSO stands for Alternatives, Value (creation, engineering), Innovation, Smarts & Optimisation and is built around a customised brainstorm process aimed at achieving business excellence through the introduction ofinnovative solutions in our methods, projects, and equipment. Sustainability is a fundamental aspect of the AViSO process, incorporated both in the formulation of challenges and throughout the ideation phase. Out of the 12 AViSO workshops conducted, seven were specifically focused on sustainability issues, including renewable energy and storage, flood protection, environmental cleanup, and social wellbeing. technical and non-technical topics. Subjects included PFAS Responsibility with a non-profit organisation, Doing Business

-

• — We held 'DEME Talks' (inspired by TED Talks) on both remediation, Sleep is the new medicine, Corporate Social within Planetary Boundaries and the Circular Economy.

12 Approved Innovation Initiatives

The ambition to achieve a sustainable world also means that intrapreneurship (whereby employees can behave like entrepreneurs, even though they work within an organisation) should be encouraged within the company. Working towards holistic, sustainable solutions also

requires in-depth knowledge, expertise and R&D on very specific topics, and dedicated cooperation with universities and research institutes. That's why we aim to enhance scientific research, upgrade our technological capabilities, and encourage sustainable innovation.

Sustainable innovation

We all hold key parts of the solution, and we all stand to benefit by collectively driving forward sustainable development. Multistakeholder partnerships therefore can be seen as a way for organisations from different societal sectors to work together.

Responsible business conduct

In our daily operations we interact with a variety of different business partners such as customers (including publicly-owned entities), joint venture partners, subcontractors, suppliers and (recruitment) agencies.

Targets

• — We only work with stakeholders committed
• to the same ethical standards as our company.
• — We ensure decent working conditions for
• everyone and encourage social dialogue. — We ensure that every employee has followed frequent training courses about ethical awareness.

Actions

• — Following a risk analysis, preliminary feasibility study, partner selection process and detailed process design, 2023 saw the kick-off of the rollout of our highly automated third-party risk management suite. The rollout of the process for Sanctions and Anti-corruption and Antibribery (ABAC) screening for suppliers is meanwhile completed for all vendors onboarded on the platform. A similar process for(joint venture) partners and customers is currently nearing completion of the design stage and the rollout will commence during the first quarter of 2024.
• — Alongside minor updates to our various (internal) compliance policies, DEME's Raising and Reporting Integrity Issues Policy received a major overhaul in 2023. In addition to a name change to "Whistleblowing Policy", improving clarity, the policy and procedures described in it were furtherrefined in order to ensure full alignment with the European Whistleblower Directive that came into force. This includes the creation of additionalreporting channels and a more streamlined procedure amongst other things. The summary is available on the DEME website.
• — Our annual Code of Ethics and Business Integrity training yielded a 99% success rate for staff on the mandatory e-learning course and 87% for crew using tailored classroom toolboxes. With nearly all masters and officers trained, we are steadily progressing towards our goal of complete ethics and integrity awareness throughout our organisation.

99% of DEME staff successfully completed compliance training

87% of DEME crew successfully completed compliance training

Additionally, due to the global nature of DEME's business, we operate in countries with a higher risk profile for non-ethical practices, which is demonstrated for example, by theirlowerranking on the Corruption Perception Index published by Transparency International. Therefore, we must remain vigilant and make sure that our ethical standards are adhered to at all times, both by ourselves and our business partners.

In line with our ambitions to create a sustainable business for the long-term with all third parties involved, we aim to conduct our business with honesty and integrity, and actively and proactively prevent corruption or bribery in any form. In addition,responsible business conduct includes other topics such as respect forlabour and human rights, abolition of child labour, combating money laundering and encouraging fair competition with our stakeholders, etc.

Reuse of concrete slabs and lifting beams

In line with DEME's commitment to circularity, existing materials were reused during the reconfiguration and installation of a crane rail at one of our project sites. The connection between the concrete base and the track is usually sealed with special plates. But instead of buying new ones, the team cleverly used 1,725 m2 of leftover concrete slabs from another DEME project site.

Additionally, lifting beams from dyke reinforcement project GOVa got a second life as collision protection. This not only prevents these beams from ending up as waste but also establishes a safer working environment. The distinctive colour of the lifting beams ensures their visibility and clearly marks height differences. Additionally, these beams can still be used as lifting equipment in the future. This clever solution resulted in a reduction of almost 123 ton of CO2 emissions.

Mitigating noise impact using artificial intelligence

At Vineyard Wind 1, the first commercial-scale offshore wind farm in the US, DEME is working closely with the Bureau of Ocean Energy Management (BOEM) and bringing its operational experience and noise mitigation expertise to the project. Due to the high density of whales in the area, it is vital to minimise the impact of underwater noise from pile driving. Therefore, DEME deployed three offshore noise abatement systems: two single bubble curtains and an enhanced Hydro Sound Damper net around the monopiles. In addition to these state-of-the-art mitigation technologies, we implemented an extensive marine mammal observation system to detect protected species before they entered the zone where potential noise could impact their behaviour. This was based on a combination of underwater acoustic technology and above-water visual observation systems. Aided by artificial intelligence and infrared camera technologies, DEME, in collaboration with its customer and subcontractors, was able to significantly reduce the impact of noise from pile driving.

DEME was granted the prestigious title of 'Pioneering Employer 2024' (Baanbrekende Werkgever 2024). Awarded by the Baanbrekende Werkgever partnership, the title recognises our commitment to fostering a healthy work environment and people-oriented employment, demonstrated by our policy regarding hybrid working and mobility amongst others.

Currently, efforts are underway to reinforce and initiate various Health & Wellbeing initiatives.

Replacement of disposable ballast system with recoverable one

In the past, DEME's geophysical and Geographic information system (GIS) specialist, G-tec, used to work with a ballast system that is composed of disposable sandbags, connection pieces (such as shackles) and rope between the ballast and transponder. Usually, an underwater acoustic release system was used but with a keen focus on sustainability, G-tec explored ways to avoid the loss of the ballast system to the seabed. In the end, the project team came up with an innovative idea to use a capstan mounted on the back deck to recover the full setup (buoy,rope, transponder, connection pieces,rope and the ballast). The capstan reduces manual handling on deck and allows the full setup to be recovered efficiently so it can be reused for projects in the future.

Best practices other themes

In the spirit of Ramadan, the Abu Qir 2 project in Alexandria stepped up to support the local community. The project team put together special gift boxes with essential supplies and distributed them to the underprivileged, working together with a local charity.

First energy island off the Belgian North Sea coast

Together with our customer Elia, we are building the world's first energy island off the Belgian North Sea coast. To go beyond compliant mitigation and management of the potential disruptive effects the island will have on the surrounding marine environment, a natureinclusive design (NID) approach is being explored.

DEME was involved in the co-creation process with a group of experts, who are aiming to embed real ecological and environmental value into this project. This resulted in 10 recommendations and different NID models - selected based on their compatibility and interactions to strengthen the overall ecological added value of the local marine ecosystem.

Based on ourin-house expertise, we explored the technical and economic feasibility of these models during the detailed design phase, in addition to considering the installation and efficient management of these frontrunning NID measures. Combined with a dedicated scientific follow-up, these pioneering studies will enable DEME to claim a unique leadership position with regard to the NID of energy islands.

Collaboration with our stakeholders

As a global company operating in many different markets and locations, it is essential to maintain good working relationships with all our stakeholders.

DEME strongly believes in joining forces to enlarge the overall sustainability impact. Our approach is to participate in multistakeholder partnerships and inter- and intra-industry collaborations to drive the transition towards holistic, sustainable solutions. An extensive list of partnerships related to energy and emissions reduction is available on our website, www.deme-group.com.

EU Taxonomy

The EU Taxonomy is a classification system establishing a list of environmentally sustainable economic activities. The goal of the legislation is to play an important role in helping the EU scale up sustainable investment and to support the implementation of the European Green Deal.

For the financial year 2023, DEME is reporting according to the EU Taxonomy standards in compliance with the Non-Financial Reporting Directive and the EU Taxonomy Regulation. DEME performed an eligibility assessment based on the EU Taxonomy Regulation's six environmental objectives to disclose the proportion of Taxonomy-eligible and non-eligible activities of the total turnover, capital expenditure (CapEx) and operational expenditure (OpEx). In addition, DEME performed an alignment

assessment on its Taxonomy-eligible activities related to the Delegated Acts on Climate Change Mitigation (CCM) and Climate Change Adaptation (CCA) to disclose the share of Taxonomyaligned activities. The assessments were carried out on projects executed in 2023. Compliance with the Minimum Social Safeguards has been verified. The calculation of the proportion of the Taxonomy-eligible and -aligned activities in turnoveris based on DEME's official IFRS reporting as per 31 December 2023, and for capital expenditure, this calculation is based on DEME's CapEx plan as of 31 December 2023. OpEx as defined in the Taxonomy Regulation is negligeable and further analysis would not have resulted in a significant amount of eligible or aligned OpEx based on the EU Taxonomy. Therefore, the indicatoris considered immaterial. The table below summarises the results of these evaluations. The official EU Taxonomy reporting tables are in the Annexes.

Certificates and ESG ratings

Certificates

Environmental, social, and corporate governance (ESG) ratings

DEME meets international and local legalregulations, but it always aims to operate at higher standards than only meeting the mandatory requirements. DEME holds an ISO Group certificate including more than 50 entities.

	All certified entities are compliant with the following standards:
ISO 9001	Quality Management Systems
ISO 14001	Environmental Management Systems
ISO 45001	Occupational Health and Safety Management Systems
ISO 50001	Energy Management Systems
Additionally, local certificates are in place, such as:

— CO2 Performance Ladder

— SHE Checklist for Contractors (SCC)

DEME's sustainability performance has been assessed by multiple ESG analysts. The ESG ratings indicate the sustainability performance of a company based on publicly available information. During 2023, we maintained our positioning in the ESG ratings versus previous years as shown in the table below.

	Rating scale	Rating score 2023	Rating score 2022	Rating score 2021	Sector ranking 2023	Sector average rating 2023	DEME Trend vs 2022

(2) The Sustainalytics ESG Rating gives a lower score to companies with less exposure and better management of their ESG risks.

(3) Scores given are covering the scope of the CFE Group before DEME's separate listing.

Based on the current interpretation of the rules regarding the EU Taxonomy, DEME's eligible activities expanded in 2023 beyond offshore wind and rail infrastructure to include parts of DEME's environmental activities, such as remediation of contaminated sites and soil and sediment management.

As a result of this expanded scope and stronger growth in eligible activities, 42% of the total turnoveris now eligible compared to 29% in 2022. 33% of the turnoveris now qualified as aligned compared to 26% in 2022.

Taxonomy-eligible and aligned capital expenditures remained in the same range at 49%, compared to 52% in 2022, while the investment scope shifted from vessels such as 'Orion' and 'Viking Neptun' in previous years to investments in 'Yellowstone', the new fallpipe vessel.

Information provided to and sustainability matters addressed by the Board of Directors and the Audit Committee

DEME Group is convinced of the positive influence of diversity-based human resources and employment policies and practices. As a result thereof, DEME Group sees the attraction, development and career counselling of talented staff as a priority. The composition of our Board of Directors and Executive Committee also reflects our diversity policy in terms of professional background, skills and gender.

With regard to the composition of the Executive Committee (see Charter,

paragraph 4.2), the Board of Directors must also ensure that the members have diverse professional backgrounds with complementary skills. It is the aim of the Board of Directors that the long-term vision of the DEME Group is supported by executives who actively promote the values of the company and, in this sense, contribute to value creation. This translates, among other aspects, into a preference for providing talented staff members with career development opportunities within the DEME Group.

All members of the Executive Committee have been appointed from within the DEME Group based on their personal merits.

Finally, DEME has ongoing investments in training, development, career counselling and the retention of staff members. This is done through a combination of broadening and deepening knowledge through training programs, seminars and workshops, career perspectives within the DEME Group, and through a market-compliant and competitive remuneration policy.

This table presents the information provided to the Board of Directors and the Audit Committee and the sustainability matters deliberated upon during their meetings.

DEME Group became a publicly listed company at the end of June 2022, marking a significant milestone. Over the subsequent 18 months, the company navigated its new status with diligence, establishing consistent reporting cycles and fulfilling the obligations associated with being listed on the stock exchange market. This included conducting earnings calls, convening DEME's first Annual General Assembly as a publicly listed company, and actively engaging with both sell-side and buy-side investors. As DEME shaped its investorrelations strategy, it also began to build a commendable track record. As a result, stakeholders gained a clearer understanding of the company's identity and communication style.

Reflecting on 2023, DEME's first full year as a listed entity commenced on a positive note, with its share price peaking at 134 euros in early January. Throughout the first half of the year, the stock remained relatively stable,fluctuating between 110 and 130 euros. However, amid concerns surrounding the offshore market, the share price experienced a decline, bottoming out at 84 euros in late October. Nonetheless, DEME demonstrated resilience, closing the year with a share price of 111 euros. Notably, the stock experienced a decline of approximately 10% over the year, contrasting with the BEL 20 index, which maintained a relatively stable performance over 2023.

Risk management

Within the context of its business operations, DEME is exposed to a wide variety of risks that can affect its ability to achieve its business objectives and execute its business strategy successfully. Risk management is the identification, evaluation and prioritisation of risks, followed by a structured and continuous process to monitor, manage and mitigate the probability and the impact of unforeseen events or to maximise the realisation of opportunities.

Overview of the different risk domains and risk items

An overall description of the these risks, as well as their potential impact and respective risk management and control is provided in the Chpater 7 Appendix - Risk Assessment

Control Environment

The control environment can be defined as the system developed and implemented by management, which contributes to managing the activities of the Group, the overall functioning and the proper use of its assets, aligned with the Group's objectives and complexity of its operations. DEME's control environment, which consists of policies, procedures and departments that ensure the internal controls work effectively, is outlined in this chapter.

DEME has a set of supportive programs, systems, policies and procedures that provide the foundation of its internal control environment. These include:

Code of Ethics & Business Integrity

First of all, there is the Code of Ethics & Business Integrity. It is everyone's personalresponsibility to adhere to it and this is applicable to all directors, company representatives, staff and crew,full- and part-time employees (permanent and temporary), whether working under a contract or on a freelance basis for DEME and its subsidiaries.

The principles of the Code are simple and clear: at all times, comply with the applicable laws and regulations, act with integrity and honesty and avoid inappropriate behaviour, or even the appearance thereof. The Code covers important areas such as protecting people and company assets, principles on preventing discrimination & harassment, antibribery and anti-corruption, compliance with international trade laws, and accounting standards and records.

In order to make sure everyone understands the Code and applies it properly in their daily activity,regular obligatory training sessions are organised. In addition, DEME expects any third-party it does business with, to respect and act according to the Code's principles.

Project execution

Secondly, with respect to project execution, DEME has a universal approach in dealing with projects from evaluation and preparation to execution, including the way these are governed. During tendering, the Acquisition & Tender Management Manual (ATMM) is used, whilst the Project Management System (PMS) Framework is applied during the project's lifecycle. Both are connected using the Project Lifecycle and Governance Manual.

Signature authorities

Thirdly, there is the internal procedure on signature authorities valid for approval on all commitments made by the DEME Group towards external parties. The objective is to streamline the procedure across the entire organisation. It includes the approval of outgoing purchase orders, contracts, invoices, etc. In order to achieve this DEME has developed the Internal Approval Solution to verify the limited list of employees who have the authority up to a certain monetary limit.

01. DEME's risk management and control system

DEME's risk management and control system is based on the Code of Companies and Associations and DEME's Corporate Governance Charter. These are available on DEME's Investor portal which includes more information on how risks are integrated and managed as part ofits corporate governance practice.

02. Objectives

When assessing risks and opportunities, the following objectives are always put forward to provide a directional context in the decision taking process.

• — Operational & Strategic objectives
• — Continuity & Operational excellence
• — Compliance with all applicable laws and regulations
• — Correct and timely financialreporting

03. Governance

DEME's risk management and control system is based on the Code of Companies and Associations and DEME's Corporate Governance Charter. These are available on DEME's Investor portal which includes more information on how risks are integrated and managed as part ofits corporate governance practice.

• — Risk management and control processes are actively supported by the Board of Directors and the respective Board committees.
• — They understand the risks that DEME is facing and ensure that these are effectively managed, with the CEO and Executive Committee fully engaged in risk management.
• — Furthermore,risk mitigation and control are a core task of DEME's management team and by extension, all executives with management responsibilities be it in the different segments or in one of the functional domains of the company .

04. Programs & systems in place

Risk assessment & management

Based on the supportive systems and programmes in place, a continuous assessment is performed and centralised at Executive Committee level. Input for this assessment comes from several departments.

Integrated software solutions

Fourthly, DEME has chosen integrated software solutions across its subsidiaries which guarantee a consistent approach.

For accounting, DEME mainly uses Microsoft Dynamics 365 with an ongoing rollout plan forlegacy entities using AX 2009 and AX 2012. D365 ensures the uniform processing of all data within theGroup. In the area of digitisation, DEME forges ahead with automatic data recognition and e-invoicing. DEME also set up a payment factory named Trax, which is a centralised platform to execute payment instructions and receive bank statements. The payment factory is linked to Bridgerfrom LexisNexis, a sanctions' screening tool, hence outgoing payments are checked regarding sanctions before any disbursement is made.

Uniformity ofreporting is a priority for DEME. The financialreporting system, a tailor-made multidimensional database, is integrated in the transaction systems and is fed live. Consolidated financial statements and management reports are automatically linked, allowing perfect alignment between the different reports.

For procurement, a gradualrollout is ongoing where new projects adopt Ivalua. This software manages the process from onboarding suppliers, screening a vendorfor compliance, to making and following up on purchases. The uniform software helps DEME make data-driven decisions (identify spending patterns, trends and opportunities for cost savings) which enables informed choices regarding sourcing strategies, supplier selection, and contract negotiations. Furthermore, it streamlines the procurement process and secures DEME's governance because of built-in controls such as compliance screening and the Internal Approval Solution.

Unified Reporting

In Finance, clearreporting instructions with timely communication of deadlines, standardised reporting formats and uniform accounting principles are in place. Worldwide allfinance employees use the same methodology, namely DEME's Project Administration & Finance Manual. It details accounting policies and procedures, analytical coding and statutory reporting among others. It is supported by the Finance Processes Portal which charts the key processes using Mavim software.

As an international contractor, both incoming and outgoing guarantees are an important measure in doing business. In order to manage this, the Treasury & Structured Finance Department operates a system which logs and keeps track of all securities such as guarantees, letters of credit, surety bonds, comfort letters etc.

01. The Opportunity and Risk Management Department

monitors opportunities and risks for all projects in a transparent, systematic, and homogeneous mannerfrom the tender phase until completion.

02. The Internal Audit Department

provides independent and objective assurance about the risk management, governance, business and internal control processes by providing a systematic approach to evaluate and improve processes, as well as conducting internal audits and advisory activities. The Internal Audit Department conducts risk-based audits and advisory services based on annual plans approved by the Audit Committee. It monitors the execution of action plans and collaborates with statutory auditors to share key findings. Advisory services are based on specific requests from the Executive or Audit Committee and include regular meetings with risk management stakeholders, lessons learned analysis, and awareness campaigns.

03. The Enterprise

Security Office (ESO)

has the mission to advise and assist Senior Management in protecting the assets of the DEME Group against all risks of malicious origin. This can include everything from sabotage,fraud and piracy to aggressive information gathering, cyberattacks and damage to DEME's image.

04. The QHSE Department

embodies the 'Zero accidents and zero environmental incidents' ambition of the DEME Group. The company's priority is always the wellbeing of employees and subcontractors, highlighted by DEME's high quality, healthy, safe and eco-friendly work environment. QHSE is always a topic on the agenda of DEME's Management Team, the DEME's Executive Committee and Board of Directors' meetings. Key Performance Indicators are used to track QHSE performance, including both indicators like green initiatives and the safety thermometer.

QHSE management system

DEME has a robust Quality, Health, Safety and Environment (QHSE) management system in place. Reflecting the diversity of the activities, industries and customers, DEME works to continually improve the effectiveness ofits management system in order to ensure that the highest standards are maintained.

Therefore, DEME has obtained a number of certificates mentioned in the (non-exhaustive) list below:

• — ISO 14001, an international standard that specifies a process for controlling and continually improving a company's environmental performance.
• — ISO 9001, an international standard that applies to the processes that create and control the products and services an organisation supplies; and prescribes systematic monitoring of activities to ensure that the needs and expectations of customers are met.
• — ISO 45001, an international standard to help an organisation control all occupational health and safety risks.
• — International Safety Management (ISM) Code, the international standard for the safe management and operation of ships and the prevention of pollution. The purpose of the ISM Code is to ensure safety at sea, to prevent human injury orloss oflife and to avoid damage to the environment and the ship.
• — International Ship & Port Facility Security (ISPS) Code - a comprehensive set of measures to enhance the security of ships and port facilities.
• — CO2 P-ladder v3-0 Niv 5. The CO2 Performance Ladder is an instrument that helps companies reduce CO2. The principle of the ladderis that efforts are rewarded with a concrete advantage in the tendering process in the form of a discount on the registration price.

To emphasise that safety is the highest priority ashore and at sea, all employees have a 'Stop Work Authority' where it is everyone's responsibility to stop work that may result in any type of unwanted event, without fear ofreprisal.

Sustainability is interlinked to QHSE and DEME responds to stakeholders transparently by measuring our sustainability performance and publishing the results annually. We are guided by the Global Reporting Initiative (GRI) Standards for Sustainability Reporting. Additionally, good corporate governance is achieved by integrating four main layers within our sustainability governance structure: the Executive Committee, the Sustainability Board, the Sustainability Team and the Process Owners from the different activities and supporting services. The progress on sustainability is discussed at board meetings. We refer to the chapter on Sustainability Governance. Many of the aforementioned systems/processes are listed as tools in the Risk Register, as part of the risk management and control approach.

Key risks

The following outlines a selection of key risks that, alone or in combination with other events or circumstances, could have a material adverse effect on the company's business, strategy, financial condition and results of operations and prospects.

A more comprehensive description of risks, their potential impact and risk management and control is provided in Chapter 7 Appendix - Risk Assessment.

01.

Business and growth opportunities are subject to macroeconomic developments

DEME's activities are driven primarily by the growth of the global population, the trend to locate industry near coastlines and along majorrivers, the growth of the global economy and the need for suitable infrastructure that this growth entails, the increasing demand for energy and the transition to renewable energy and climate neutrality, the scarcity of specific minerals and raw materials, and the development ofinternational trade and shipping.

02.

Business and growth opportunities are subject to geopolitical developments

DEME's operations are, in some areas where it is active, exposed to elevated risks relating to political and/or social instability (including war and civil unrest, armed conflict, terrorism, hostage taking, piracy, extortion and sabotage).

03. Project management and execution risks

Projects are usually characterised by the obligations entered into upon the submission of the offer as part of the tendering process for a project and, upon award, the signing of a contract to construct or deliver an infrastructure or a scope of work with a unique character for an established fee or variable price and within an agreed period of time.

04.

Third-party risks in respect of contractors, suppliers, vendors, joint venture partners or other parties

The successful completion of projects depends on the ability of third parties to perform their contractual obligations and is subject to factors beyond DEME's control, including actions or omissions by these parties and their subcontractors.

Share capital amounts to 33,194 thousand euro and share premium amounts to 475,989 thousand euro. After the partial demerger of CFE NV on 29 June 2022, a new holding company DEME Group NV replaced DEME NV and the equity components of this new parent company are now reflected in the DEME Group consolidated figures. The impact of this partial demerger is reflected in the line 'other' as a transfer between retained earnings and other reserves and share capital and share premium in the consolidated statement of changes in equity of 2022. Reference is also made to note (17) share capital, dividends and reserves.

The hedging reserve includes the fair value fluctuations of effective cash flow hedges, net from income taxes. Reference is made to note (21) financial risk management and financial derivatives. The movement of the year, -31.9 million euro, also includes the changes in the hedging reserve for joint ventures and associates (-14.2 million euro). Some joint ventures and associates, mainly in the DEME Concessions segment, finance substantial assets such as infrastructure works, offshore wind farms or vessels and therefore hold interest rate swaps (IRS). In 2023, the decline in market interest rates compared to the hedged interest rates had a negative impact on the hedging reserve which explains the negative movement of -31.9 million euro in 2023.

Remeasurement on retirement benefit obligations relates to the defined benefit plans (including the Belgian contribution-based plans which are considered to be defined benefit plans under IFRS) actuarial gains/losses (-) and asset limitation, after income taxes. For more information, reference is made to note (23) retirement benefit obligations, where the remeasurement is shown before income taxes.

Retained earnings and other reserves include the revaluation surplus, legal reserve, available reserves, untaxed reserves and retained earnings of the parent company, before result appropriation of the year, as well as the consolidation reserves. The increase of 68.7 million euro in the line 'other' is related to the step-in of a partner in the company Global Sea Mineral Resources NV (GSR) within segment Concessions that is accounted for as an equity transaction. Reference is made to section changes in the consolidation scope.

Non-controlling interests amounts to 50.3 million euro at 31 December 2023. The increase of 20.4 million euro in the line 'other' is also related to the step-in of a partner in the company Global Sea Mineral Resources NV (GSR) within segment Concessions. Reference is made to section changes in the consolidation scope and to note (19) non-controlling interests.

The Group's company structure is mostly, but not completely, built around the different segments. It is possible that a company of the Group is executing projects in both the Dredging & Infra and Offshore Energy segment and also one project can trigger cost and income in different companies of the Group worldwide. The list of Group companies associated with their main operational segment for 2023 is available within the section Group structure and changes in the reporting period. The DEME operational and management structure is aligned with the DEME operational segments as well as the management reporting that is based on a worldwide uniform analytical accounting system. The analytical result by company, that gives a breakdown by project and cost center, is the basis for the segment reporting that can always be reconciled with the income statement of the company.

For projects in which two segments are involved (for instance an offshore contract with a dredging scope), the segments only report their own share in revenue and result. When one segment is working for another segment as a subcontractor or when a segment hires equipment, to use on projects, that is dedicated to another segment, this is remunerated at arm's length basis. Intersegment revenues are included in the revenues of the segment performing the work but are eliminated in the segment that is invoicing to the external customer. Currently intercompany sales for major projects are within the same segment (dredging and infrastructure works; offshore and salvage works) so there is no inter-segment revenue to report on separately.

For each segment the turnover, EBITDA, depreciation and impairment cost and EBIT is reported. For the Concessions segment these measures of performance are only applicable to the subsidiaries (fully consolidated entities included in this segment). As the business of the Concessions segment is often resulting in a minority stake in participations, the operating result of these participations is reflected in the result from associates and joint ventures that is also segmented. The basis for the segment reporting is the management reporting system. Next to all activities done by our subsidiaries, the management report also

includes the projects executed by joint ventures, showing the DEME's share of revenues and expenses in the joint venture. This proportionate consolidation method whereby the Group accounts for the assets, liabilities, revenues and expenses according to its share in the joint venture, is not allowed under IFRS for joint ventures. Management however has to monitor the performance of the entire business, both executed in control as in a joint venture. In the segment reporting the joint ventures are consolidated according to the proportionate consolidation method and the intercompany transactions between the joint ventures and DEME subsidiaries are eliminated following the rules of proportionate consolidation. The total of the reported segment amounts is reconciled with the corresponding amounts in the DEME consolidated financial statements. The Share of the Group (IFRS net result) is not affected by the difference in consolidation method, only the presentation of the result of the year is different.

As for the net result from joint ventures and associates and the carrying amount of joint ventures and associates, the reconciliation column includes the net result and carrying amount of joint ventures that are consolidated according to the equity method in the financial statements but according to the proportionate consolidation method in the segment reporting. Reference is made to note (9) for more information about joint ventures and associates.

DEME's management reporting focuses on both the current and future (financial) performance and on the current and future assets deployed for the execution of projects. The financing activities and monitoring of our working capital is performed centrally at DEME Group level, and therefore no segmented financial information is presented for those activities.

The segmentation of DEME's fleet is done based upon the nature of the equipment dedicated to a specific segment. An overview of the DEME fleet per nature is attached in the Annual Report 2023. A geographical segmentation of the fleet is not applicable for DEME as its vessels are continuously deployed on different projects around the world.

Segment reporting

Description of operating segments

For management purposes, the Group is organised into four business units based on its products and services. The four reportable segments are:

Offshore energy

This segment provides engineering and contracting services globally in the offshore renewables and oil & gas industry. Those activities are executed with specialised offshore vessels. In the offshore renewables, the Group is involved in the full Balance of Plant scope for offshore wind farms. This includes the engineering, procurement, construction and installation of foundations, turbines, inter-array cables, export cables and substations. The Group also offers operations and maintenance, logistics, repair and decommissioning as well as salvage services to the market. In the oil & gas industry, the Group performs landfalls and civil works, rock placement, heavy lift, umbilicals, as well as installation and decommissioning services. In addition to these main activities, the Group also provides specialised offshore services, including geoscience services and the installation of suction pile anchors and foundations.

Dredging & Infra

In this segment the Group performs a wide variety of dredging activities worldwide, including capital and maintenance dredging, land reclamation, soil improvement, port construction, coastal protection and beach nourishment works. These activities are executed with specialised dredging vessels and various types of auxiliary vessels and earth-moving equipment. The Group also provides contracting services for marine infrastructure projects. This includes the engineering, design and construction of complex marine structures such as jetties, port terminals, locks and weirs, infrastructural works such as bored and immersed tunnels, foundation and marine works for bridges or other constructions in a marine or fluvial environment, and civil works for harbour construction, dams and sea defences, canal construction, revetment, quay wall construction and shore protection. In addition, the Group is active in the marine aggregate business, which includes dredging, processing, storage and transport of aggregates. Finally, the Group provides maritime services for port terminals.

Environmental

The Environmental segment focuses on innovative environmental solutions for soil remediation and brownfield redevelopment, environmental dredging and sediment treatment and water treatment. It is mainly active in the Benelux, France, as well as in other European countries on a project-by-project basis. An external partner participates in the Environmental segment. The segment can be considered as a material partly owned aggregated level of subsidiaries with non-controlling interests of 25.1%. Reference is made to note (19) non-controlling interests.

Concessions

The Concessions segment, unlike the contracting segments, invests in and develops projects in wind, port infrastructure, green hydrogen and other special projects. It operates through participations in special purpose companies – greenfield and brownfield. Besides creating economic value on its projects and generating equity returns on its investments, it also aims to secure regular activities for the Group contracting activities in the EPC phases of its projects. Within its concessions activities, the Group also holds concessions of seabed areas which contain polymetallic nodules and develops a technology to collect and process these polymetallic nodules containing nickel, cobalt, manganese and copper from the deep ocean floor.

Each of the four abovementioned segments has its own market, asset base and revenue model and is managed separately requiring different strategies. Dredging & Infra activities are complementary as the marine infrastructure works that DEME Infra undertakes are often combined with a dredging or land reclamation scope. The Offshore Energy segment is involved in and serves the offshore energy industry, both renewables and oil & gas sectors. The Environmental segment focuses on environmental solutions. The Concessions segment, unlike the contracting segments, invests in and develops projects in wind, port infrastructure, green hydrogen and other special projects.

The segment reporting comprises financial information of these four segments that are separate operating segments. On a quarterly basis, separate operating results are prepared and reported to the Chief Operating decision maker, the DEME Executive Committee, as well as the Board of Directors.

For the segment reporting, some activity lines, that are the lowest level of reportable activities within DEME, are aggregated. As such the activities of Combined Marine Terminal Operations Worldwide NV (CTOW) in the maritime services for port terminals and Deme Building Materials NV (DBM) in the marine aggregate business are aggregated in the Dredging & Infra segment. The works performed by Scaldis Salvage & Marine Contractors NV (salvage works) are aggregated in the Offshore Energy segment.

The reporting of the management accounts (reporting on operating results) is an integral part of the financial reporting. At any time, the consolidated management report can be reconciled with the consolidated financial statements, both resulting in the same IFRS net result of the year (as such one version of the truth).

(*) Acquisitions according to balance sheet (rollforward property, plant and equipment and right-of-use assets) and not according to cash flow statement.

The financial information disclosed in the segment reporting (using the proportionate consolidation method for joint ventures) is reconciled with the financial information as reported in the consolidated statement of financial position and the consolidated statement of income (using the equity consolidation method as required under IAS 28) above. The impact of the different consolidation method for joint ventures is included in the 'reconciliation' column. The proportionate (line-by-line) integrated amounts of joint ventures are deducted and replaced by the Group's share in the result of the joint ventures. In addition, turnover of fully consolidated entities towards joint ventures (that is proportionally eliminated in the segment reporting), is added

again to the turnover in the Group financial statements, as this turnover is not eliminated any longer when joint ventures are consolidated according to the equity method. Therefore, the ratio between EBITDA/EBIT and turnover of the 'reconciliation' column is not reflecting the ratio of the joint ventures itself. Associates are consolidated according to the equity method in both the segment reporting and the Group financial statements. The lines referring to 'net result of joint ventures and associates' or 'capital investments in joint ventures and associates' in the segment reporting only include associates, while the joint ventures are added in the reconciling items. Reference is made to note (9) for more information about joint ventures and associates.

Below amendments apply for the first time in 2023, but do not have an impact on the consolidated financial statements of the Group:

• IFRS 17 insurance contracts
• amendments to IAS 8 accounting policies, changes in accounting estimates and errors: definition of accounting estimates
• amendments to IAS 12 income taxes: deferred tax related to assets and liabilities arising from a single transaction

Below amendments apply for the first time in 2023 and have an impact on the consolidated financial statements of the Group:

• amendments to IAS 12 income taxes: Pillar Two Model Rules International Tax Reform. The amendments include a temporary exception to the recognition and disclosure of deferred taxes arising from the jurisdictional implementation of the Pillar Two model rules. Following the amendments, the Group is required to disclose that is has applied the exception and to disclose separately its current tax expense (income) related to the Pillar Two income taxes. Reference is made to note (11) current taxes and deferred taxes
• amendments to IAS 1 presentation of financial statements and IFRS practice statement 2 making materiality judgements: provide guidance and examples to help entities apply materiality judgements to accounting policy disclosures. The amendments had an impact on the Group's disclosures of accounting policies, but not on the measurement, recognition or presentation of any item in the Group's financial statements

The standards and interpretations that are issued, but not yet effective, as of 31 December 2023 are disclosed below:

• amendments to IAS 1 presentation of financial statements: noncurrent liabilities with covenants and classification of liabilities as current or non-current (deferred), effective 1 January 2024 (*) - amendments to IFRS 16 leases: lease liability in a sale and leaseback, effective 1 January 2024
• amendments to IAS 7 statement of cash flows and IFRS 7 financial instruments: disclosures to clarify the characteristics of supplier finance arrangements and require additional disclosure of such arrangements, effective 1 January 2024 (*)
• amendments to IAS 21 the effects of changes in foreign exchange rates: the lack of exchangeability, effective 1 January 2025 (*)

(*) The amendments to the standard have not yet been endorsed.

The Group intends to adopt these standards and interpretations, if applicable, when they become effective. None of these standards issued, but not yet effective, are expected to have a material impact on the financial statements.

Significant judgements and estimates

The preparation of financial statements under IFRSs requires estimates to be used and assumptions to be made that affect the amounts shown in those financial statements, particularly with regarding to the following items:

• the assessment of projects revenue according to the percentage of completion: in accordance with the provisions of IFRS 15, the revenue of projects is measured by reference to the stage of completion of the contract activity at the end of the reporting period, measured based on the proportion of contract costs incurred for work performed to date relative to the estimated total contract costs, except where this would not be representative of the stage of completion. Identified additional costs are incorporated in the estimated result at completion. On the basis of the contractual conditions that are defined for each contract, any compensation granted or, conversely, penalties charged for delays are also incorporated in the estimated result at completion in line with the valuation rules of the DEME group. When the outcome of a construction contract cannot be estimated reliably, contract revenue is recognised to the extent of project costs incurred that will probably be recoverable. In the event that the forecast at the completion of the project shows a deficit, the expected loss on completion is immediately recognised as an expense for the period, based upon the principles of IAS 37 provisions, contingent liabilities and contingent assets for onerous contracts at the best estimate of the expenditure required to settle the obligation. As such the expected loss to record will reflect management expectations about the costs of satisfying the obligation less the amount to be received from the customer
• the period over which non-current assets are depreciated or amortised and the estimate related to the residual value - the estimate being the discount rate and the judgement of the lease term
• the measurement of provisions and pension obligations
• the estimates used in impairment tests that have been carried out. For assets where the lower of the value in use or the fair value less costs to sell was lower than the carrying amount, impairment losses were recognised. The main assumptions applied are described in note (6) goodwill
• the estimates used in the assessment of income taxes or uncertain tax positions (see note (11) current taxes and deferred taxes)
• the assessment of control

These estimates assume the operation is a going concern and are based on the basis of the information available at that moment.

Estimates may be revised if the circumstances on which they were based alter or if new information becomes available. Estimates consider changes in the macroeconomic and geopolitical environment. Actual results may be different from these estimates.

Summary of material accounting principles

General statement

DEME is specialised in offshore energy, dredging and marine infrastructure, environmental and concessions projects. DEME offers solutions for its clients at the interface of land, water and energy. For almost 150 years, DEME creates value for its shareholders and delivers projects in a safe, sustainable and efficient way with the best people, the right assets, technical leadership and effective resource allocation.

The company can as such build on a lot of experience and is a front runner in innovation and new technologies. DEME's vision is to work towards a sustainable future by offering solutions for global challenges: a rising sea level, a growing population and fast urbanisation, the reduction of emissions, polluted rivers and soils, the scarcity of mineral resources and the rising maritime trade activity that acquires constant marine infrastructure upgrades to ensure vessel access and suitable ports. Through its diversified portfolio of activities DEME is well positioned to tackle each of one of those challenges. DEME can rely on more than 5,300 highly skilled professionals and operates one of the largest and most technologically advanced fleets in the world.

While the company's roots are in Belgium, DEME has built a strong presence in all of the world's seas and continents.

Up to 29 June 2022, the parent company of the DEME Group was Dredging, Environmental and Marine Engineering NV (DEME NV). Since then, a new holding company, DEME Group NV, has come on top of DEME NV as a result of the partial demerger of CFE NV, that transferred its 100% stake in DEME NV to DEME Group NV. Reference is made to note (17) share capital, dividends and reserves, for more information about this transaction and the current shareholder structure of the DEME Group.

Both the head office and registered address of the new parent company, DEME Group NV, as well as DEME NV, a 100% affiliate of DEME Group NV, are Scheldedijk 30, Zwijndrecht, Belgium.

The companies are registered at the Chamber of Commerce (VAT number) in Antwerp, Belgium with number BE 0787829347 and BE 0400473705 respectively. The legal entity identifier (LEI) of DEME Group NV at the Crossroad Bank of Enterprises is 549300FPFPQPKI3PJV37.

DEME Group NV is listed since 30 June 2022, on Euronext Brussels under the symbol 'DEME.BR' and ISIN code BE 0974413453. For the purposes of the EU Directive 2004/109/EC in respect of the harmonisation of transparency requirements relating to information about issuers whose securities are admitted to trading on a regulated market and amending Directive 2001/34/EC, the Home Member State is Belgium. DEME Group NV shall notify the Belgian Financial Services and Market Authority (FSMA), as competent supervisory market authority of its Home Member State. DEME Group's securities are only admitted to trading in Belgium.

The website of the Group is www. deme-group.com.

The consolidated financial statements of DEME Group NV for 2023 and 2022 include the Company and group companies hereinafter referred to jointly as the 'Group' and individually as subsidiaries, joint ventures and associates. The section principles of consolidation explains how group companies are included in the consolidated financial statements.

The consolidated key figures, consolidated statement of income, consolidated statement of financial position, consolidated statement of cash flows and all explanatory notes as well as the management reporting and segment reporting were presented to the Board of Directors of 21 February 2024. The Annual Report is presented and authorised for publication by the Board of Directors on 25 March 2024.

Statement of compliance

The consolidated financial statements and the accompanying explanatory notes have been prepared in accordance with International Financial Reporting Standards (IFRS) as adopted by the European Union (EU-IFRS).

Basis of preparation

The Group has prepared the financial statements on the basis that it will continue to operate as a going concern. The Directors consider that there are no material uncertainties that may cast significant doubt over this assumption.

The consolidated financial statements are presented in thousands of euro. They are prepared on the historical cost basis except for derivative financial instruments which are stated at fair value.

The consolidated financial statements are prepared as of and for the period ending 31 December 2023.

They are presented before the effect of the profit appropriation proposed to the Shareholders' General Meeting.

In application of IFRS 1 first-time adoption of International Financial Reporting Standards, the Group has applied consistent accounting principles, based on IFRS-EU, for all the periods presented in these financial statements except for the adoption of new standards effective as of 1 January 2023. The Group has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

The following impacts of climate change were assessed in the consolidated financial statements:

• the impact of climate change on the residual values and useful lives of assets were considered in determining the carrying value of non-current assets (see note (7) property, plant and equipment)
• the impact of climate change was considered in relation to the recognition and measurement of provisions and contingencies (see note (25) provisions and contingent assets and liabilities)
• the impact of climate change was considered in relation to indications of impairment and the forecast of cash flows used in the impairment assessments of the carrying value of noncurrent assets including goodwill (see note (6) goodwill)
• the impact of climate change was considered in the future profitability used in the assessment of the recoverability of deferred tax assets (see note (11) current taxes and deferred taxes)

In summary, for the year ended 31 December 2023, no material impact on financial reporting judgement and estimates arising from climate change were identified and as a result the valuations of assets and liabilities have not been significantly impacted by climate change risks. Further, the Group concludes that the climate change risk does not impact the going concern assessment for December 2023.

For the DEME Group, efforts to mitigate and adapt to climate change worldwide generate opportunities as the Group advances the energy transition by developing infrastructure for renewable energy, provides protection against the forces of nature, and builds resilient infrastructure that is better adapted to climaterelated hazards. The Group plays a role in the move towards a circular economy with its soil remediation and brownfield development, environmental dredging and sediment treatment and invests in the production, storage, and transport of green hydrogen. Reference is made to note (1) turnover and orderbook, for the disclosure of the taxonomy-eligible turnover realised that makes a substantial contribution to climate change mitigation.

Macroeconomic matters

In 2023, the construction industry, in which DEME is working, recovered from the covid-19 pandemic and its aftermath. Though because of new geopolitical and macroeconomic challenges affecting the entire global economy, market conditions deteriorated again, leading to higher interest rates and inflation.

Interest rates globally increased in 2023 (both long-term and short-term) following several policy enhancements concluded by most central banks in their attempt to slow down inflation. As a result, financing of projects became far more expensive and led to delays in new orders or implementation of ongoing projects. In some circumstances it even led to the cancellation of some projects, following recalibration in parts of the offshore wind market. Fortunately, this had no substantial adverse effect on DEME's financials and outlook.

In 2023, DEME did not secure material new loan facilities whereas in 2022 additional long-term loan facilities totalling 440 million euro were added. To achieve the best possible balance between financing costs and the volatility of the financial results for its long-term borrowings, DEME always tries to cover the vast majority of risks of changes in underlying floating interest rates of borrowings through derivative financial instruments, mainly by using interest rate swaps. Similar to 2022, the entire Group's outstanding long-term interest-bearing debt portfolio had a fixed interest rate character, which limited the exposure of the Group to interest rate fluctuations due to rising interest rates. For shortterm financing of the year and commercial paper issued, higher interest rates were paid compared to 2022. Though in general, it can be said that the direct impact of rising interest rates on the 2023 financials remained limited for the Group.

For every company, inflation not only impacts direct costs, but it also affects indirect costs such as energy costs, salaries, etc. Although there is a considerable increase in personnel expenses as a result of the automatic indexation system in Belgium for protecting employees' purchasing power, all those costs are continuously being monitored within the Group and optimised where possible. Inflation effects are passed through to the client where possible.

During 2023, payment terms with both suppliers and clients were not extended and there has been no change in the payment behaviour of the Group towards suppliers nor in the payment behaviour from clients.

Inflation and interest rates, both impact a.o. the assessment of fair values, calculations of future cash flows, discount rates for present value calculations and impairment testing. No impairment losses allocated to cash-generating units were recognised in 2023. Further on, the valuation of the Group's assets and liabilities has not been materially affected by the above macroeconomic conditions. DEME management keeps on monitoring the macroeconomic evolution and its impact on the financials and outlook. If necessary, it will adapt its strategy.

For above topic, reference is made to note (1) turnover and orderbook, note (3) personnel expenses and employment, note (6) goodwill, note (20) interest-bearing debt and net financial debt, note (21) financial risk management and financial derivatives and note (23) retirement benefit obligations.

Disclosures related to specific topics

Climate related matters

In preparing the consolidated financial statements, the Group has considered the potential impact of climate related risks which cover both transition risks and physical risks.

Transition risk is the potential cost or decreased demand when evolving to a low carbon economy, to mitigate climate change, that can arise from changes in public sector policies (policy and legal risk), from innovation or new technologies, and from investor and customer sentiment towards a greener environment (market and reputation risk).

The main transition risks relating to the markets in which DEME operates are under review or have been reviewed to the best of the Group's knowledge. Also, the impact of potential costs is subject to pass-through clauses in the contract that are different for every project.

The EU Emissions Trading System (ETS), the world's largest carbon market, was initially established in 2005 as a market-based mechanism to tackle greenhouse gas emissions within the European Union. While it primarily targeted energy-intensive sectors like power generation and manufacturing, there have been recent developments. Directive (EU) 2023/959 of 16 May 2023 provides for the inclusion of greenhouse gas emissions from maritime transport activities into the existing European Union Emission Trading System (ETS). Emissions from maritime transport activities are included in the overall ETS cap, which defines the maximum amount of greenhouse gases that can be emitted, economy-wide, within the European Union under the system. The cap is reduced over time to ensure that all ETS sectors contribute to the EU's climate objectives. Shipping companies, including shipowners of offshore ships, are mandated to (i) report their emissions under the Monitoring, Reporting, and Verification (MRV) regulation (Regulation EU) 2023/957) and (ii) acquire and surrender (use) EU ETS emission allowances for each tonne of reported CO2 emissions, according to Directive (EU) 2023/959. The obligation to surrender ETS emission allowances applies to cargo and passenger ships of or above 5000 gross tonnage from 2024 and extends to offshore ships of the same tonnage from 2027. The EU Commission is considering the need for guidance on defining 'offshore ships', which is foreseen to be adopted in secondary legislation. It is uncertain whether the definition of 'offshore ships' will include dredging, installation, cable/pipe lying and/or jack-up vessels, among other.

The ETS system for maritime transport activities covers (i) 50% of emissions from voyages starting or ending outside of the EU and (ii) 100% of emissions that occur between two EU ports and when ships are within EU ports. During the transition phase, shipping companies will go through a gradual implementation process within the ETS: for cargo and passenger ships, 40% of their emissions reported in 2024 are required to be surrendered in 2025, followed by 70% of emissions reported in 2025 to be surrendered in 2026, and then 100% as of 2027. For offshore ships, 100% of their emissions reported in 2027 will have to be surrendered in 2028. In addition, CH4, and N2O emissions from maritime activities will be subject to control starting from 2026.

Pending the European Commission's guidance on the definition of 'offshore ships', DEME, in its capacity of owner of offshore ships, would be expected to commence reporting emissions under the MRV from 1 January 2025. Subsequently, DEME would be required to surrender 100% of the emissions of its offshore ships reported in 2027 by the year 2028.

As of 31 December 2023, no EU ETS emission allowances or renewable energy certificates are included in the consolidated statement of financial position, nor did the Group account for a liability related to GHG emissions.

The transition risk that exists because of changes in public sector policies is interrelated with the risk of potential cost following innovation and new technologies. Reference is made to chapter '04. Sustainability' where the Group's targets are described related to greenhouse gas emission reduction and the fleet. These targets were set to further increase energy efficiency, to reduce greenhouse gas emissions directly, and to be able to make the switch to the use of future zero carbon fuels in the long run.

Over time, the Group emphasis has been on enhancing the operational efficiency and productivity of DEME's fleet, leading to a decrease in the greenhouse gas (GHG) intensity. In 2023, the Group initiated a 5-year investment plan of approximately 30 million euro. The primary objective was to incorporate fuel-saving technologies across the fleet. These investment costs, along with the expenses related to integrating specific fuel-saving technologies into newly constructed vessels, are included in DEME's investment plan. In addition to the current utilisation of Low Carbon Fuels, DEME is embarking on its first pilot projects to gain practical experience with future green fuels. However, there remains a significant level of uncertainty regarding the specific fuels that will dominate the future market, their availability, and the capacity for bunkering. Consequently, estimating the precise investment required to fully prepare DEME's fleet for the transition to these future fuels is challenging. The investment costs will heavily rely on further innovations and technological breakthroughs.

Next to the fleet, DEME is working to increase energy efficiency of the offices and headquarters and invests in new sustainable technologies to have a climate neutral HQ by 2025. In 2023 the DEME LABS (new offices) have been fitted with a new cold heat storage system and dedicated heat pumps. In this way the Group obtains a fossil free heating and cooling system. Solar panels have been fitted on the roof of the DEME labs in the first quarter of 2024. In 2024 the cold heat storage system loop, previously installed on the site in Zwijndrecht, will be put into operation. The DEME LABS, the new DEME LOOKOUT and other existing buildings will be connected to this loop to optimise heat–cold management over the site. Older buildings will be demolished. Further investments will be done to equip the warehouses and the workshop with heat pumps and radiation panels to phase out the remaining fossil fuel.

As for the transport of people at DEME, that includes business flights, train travel and the car fleet, the pace at which the Group's car fleet is being electrified is increasing. The rise in lease expenses for cars in 2023 primarily results from the rapid electrification of DEME's car fleet, the expansion in fleet size (due to a higher number of cars) and the elevated lease cost associated with electric vehicles. Reference is made to note (8) right-of-use assets.

Physical risks following climate change are those related to the physical impacts such as direct damage to assets, weather delay in execution of the project and supply chain disruption. These risks can be event-driven (acute) or associated with longer-term shifts in climate patterns (chronic).

DEME has always been engaged in climate adaptation as part of the normal business risk management framework and weather delay is a contractual clause in all contracts. Damage to assets due to extreme weather conditions such as storms are covered by casualty insurance policies. When a loss occurs, the negative impact on the result that is not covered or refunded by the client is considered in the end of project margin or recognised in expenses in the related reporting period.

When a group entity transacts with an associate or a joint venture of the Group, profits and losses resulting from the transactions with the associate or joint venture are recognised in the Group's consolidated financial statements only to the extent of interests in the associate or joint venture that are not related to the Group. The gross amount on transactions with associates or joint ventures is not eliminated; only any gain or loss on these transactions is eliminated.

A joint operation is a joint arrangement in which the parties (joint operators) have direct rights over the assets and direct obligations with respect to the entity's liabilities. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control. When a DEME Group entity starts activity in a joint operation, the Group recognises, in relation to its interest in the joint operation:

• its assets, including its share of any assets held jointly
• its liabilities, including its share of any liabilities incurred held jointly
• its revenue from the sale of its share of the output arising from the joint operation
• its share of the revenue from the sale of its share of the output by the joint operation
• its expenses, including its share of any expenses incurred jointly

The group accounts for the assets, liabilities, revenues and expenses relating to its interest in a joint operation in accordance with the IFRSs applicable to the particular assets, liabilities, revenues and expenses.

When a group entity transacts with a joint operation in which a group entity is a joint operator (such as a sale or contribution of assets), the Group is considered to be conducting the transaction with the other parties to the joint operation, and gains and losses resulting from the transactions are recognised in the Group's consolidated financial statements only to the extent of other parties' interests in the joint operation.

When a group entity transacts with a joint operation in which a group entity is a joint operator (such as a purchase of assets), the Group does not recognise its share of the gains and losses until it resells those assets to a third party.

Within the DEME Group there are also project driven construction consortiums that are not structured as a separate legal entity. They are directly integrated in the figures of the DEME subsidiary that is participating in the consortium. They are considered as joint operations and thus follow the accounting method described above (integration on a line-by-line basis).

Foreign currencies

The Group's consolidated financial statements are presented in euro, which is also the parent company's functional currency. For each entity, the Group determines the functional currency and items included in the financial statements of each entity are measured using that functional currency.

Financial statements of foreign entities with a functional currency not equal to the euro, are translated as follows:

• assets and liabilities are translated at the year-end rate
• income and expenses are translated at the average exchange rate for the year
• shareholders' equity accounts are translated at historical exchange rates

Exchange differences arising, if any, are recognised in other comprehensive income and accumulated in equity (and attributed to non-controlling interests as appropriate).

Foreign currency transactions are accounted for at exchange rates prevailing at the date of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated at the balance sheet date rate. Gains and losses resulting from the settlement of foreign currency transactions and from the translation of monetary assets and liabilities denominated in foreign currencies are recognised in the income statement. Nonmonetary items that are measured in terms of historical cost in a foreign currency are not retranslated.

On the disposal of a foreign operation (i.e. a disposal of the Group's entire interest in a foreign operation, a disposal involving loss of control over a subsidiary that includes a foreign operation), all of the exchange differences accumulated in equity in respect of that operation attributable to the owner of the Company are reclassified to profit or loss.

The Group uses the direct method of consolidation and on disposal of a foreign operation, the gain or loss that is reclassified to profit or loss reflects the amount that arises from using this method. In case of a partial disposal of a subsidiary that includes a foreign operation that does not result in the Group losing control over the subsidiary, the proportionate share of accumulated exchange differences is reattributed to non-controlling interests and are not recognised in profit or loss. For all other partial disposals (i.e. partial disposals of associates or joint arrangements that do not result in the Group losing significant influence or joint control), the proportionate share of the accumulated exchange differences is reclassified to profit or loss.

In note (21) a table with currency rates from foreign currency to EUR can be found as per 31 December 2023 and 2022.

Principles of consolidation

The consolidated financial statements incorporate the financial statements of the Company and of subsidiaries which are entities controlled by the Company (fully consolidated entities).

Control is achieved when the Company:

• has power over the investee
• is exposed, or has rights, to variable returns from its involvement with the investee
• has the ability to use its power to affect its returns

The Company reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above.

Consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses control of the subsidiary. Specifically, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated statement of income and other comprehensive income from the date the Company gains control until the date when the Company ceases to control the subsidiary.

Profit or loss and each component of other comprehensive income are attributed to the owners of the Company and to the noncontrolling interests. Total comprehensive income of subsidiaries is attributed to the owners of the Company and to the noncontrolling interests, even if this results in the non-controlling interests having a deficit balance. When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies in line with the Group's accounting policies.

All intragroup assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full in the consolidated financial statements.

Changes in the Group's ownership interests in subsidiaries that do not result in the Group losing control over the subsidiaries are accounted for as equity transactions. The carrying amounts of the Group's interests and the non-controlling interests are adjusted to reflect the changes in their respective interests in the subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognised directly in equity and attributed to the owners of the Company. When the Group loses control of a subsidiary, a gain orloss is recognised in profit or loss and is calculated as the difference between (i) the aggregate of the fair value of the consideration received and the fair value of any retained interest and (ii) the previous carrying amount of the assets (including goodwill) and liabilities of the subsidiary and any non-controlling interests. All amounts previously recognised in other comprehensive income in relation to that subsidiary are accounted for as if the Group had directly disposed of the related assets or liabilities of the subsidiary (i.e. reclassified to profit or loss or transferred to another category of equity as specified/permitted by applicable IFRSs).

An investment retained is initially measured at fair value. This fair value becomes the initial carrying amount at the date when control is lost and for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset.

Associates are companies in which the DEME Group has significant influence. Significant influence is the power to take part in financial and operating policies of a company without having control or joint control over these policies.

A joint venture is a joint arrangement whereby the parties exerting joint control over the arrangement have rights to the net assets of the joint arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control.

Assets, liabilities, revenues and expenses from joint ventures and associates are accounted for under the equity method in the consolidated financial statements. Under the equity method, an investment in a joint venture or associate is firstly recorded at cost in the consolidated financial statement and then adjusted to record the share of the Group in the net result and in the comprehensive income of the associate or joint venture. When the Group's share of losses of an associate or a joint venture exceeds the Group's interest in that associate or joint venture (which includes any long-term interests that, in substance, form part of the Group's net investment in the associate or joint venture), the Group discontinues recognising its share of further losses. Additional losses are recognised only to the extent that the Group has incurred legal or constructive obligations or made payments on behalf of the associate or joint venture. These losses are recorded as other non-current financial liability on the balance sheet instead of a negative investment within non-current financial assets (note (9)).

The proportionate consolidation method whereby the Group accounts for the assets, liabilities, revenues and expenses according to its interest in the joint venture, is not allowed under IFRS but is still applied in the management reporting which is the basis for the segment reporting. Interests in joint ventures or associates are accounted for from the date when the entity becomes a joint venture or associate. At the acquisition of the interest, any surplus between the cost of the investment and the share in the fair value of net assets of the entity is recorded as goodwill included in the carrying amount of the investment. Any surplus between the share of the Group in the fair value of net assets and the cost of the investment after remeasurement is immediately recorded in the income statement during the period of acquisition of the investment.

The Group continues to use the equity method when an investment in an associate becomes an investment in a joint venture or an investment in a joint venture becomes an investment in an associate. There is no remeasurement to fair value upon such changes in ownership interests. When the Group reduces its ownership interest in an associate or a joint venture but the Group continues to use the equity method, the Group reclassifies to profit or loss the proportion of the gain or loss that had previously been recognised in other comprehensive income relating to that reduction in ownership interest if that gain or loss would be reclassified to profit or loss on the disposal of the related assets or liabilities.

Property, plant and equipment

Property, plant and equipment are measured at historical cost, less accumulated depreciation and impairment losses. Historical cost includes all direct costs and all expenditure incurred to bring the asset to its working condition and location, as well as for its intended use. Historical cost includes the original purchase price, specific borrowing costs incurred during the construction period, and related direct costs. Main dredging and offshore equipment consists of components with different useful lives that are accounted for as separate items.

Subsequent costs are included in the asset's carrying amount or recognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognised. The wear and tear of dredging equipment is highly dependent on project-specific combinations of soil conditions, material to be processed, maritime circumstances, and the intensity of the deployment of the equipment (factors that are difficult to predict). Due to these erratic and time-independent patterns, the maintenance and repair costs for upkeep of the assets during the operation of the vessel are predominantly expensed.

Dry-docking costs of the main production equipment (major repair costs) are recognised in the carrying amount of the vessel when incurred and depreciated over five years (normal period foreseen between two consequent dry dockings).

Depreciation is charged to the income statement on a straight-line basis over the useful lives taking into account an estimated residual value. Land is not depreciated as it is deemed to have an infinite life, except for landfills used for sand production that are depreciated according to the tonnes extracted. Buildings are depreciated over 25 years. The depreciation periods of the floating and other construction materials range from 3 years (such as for pipelines) to 21 years. The principal component of trailing suction hopper dredgers and cutter suction dredgers is depreciated over a period of 18 years. For new hopper dredgers, cutter suction dredgers, cable lay vessels and DP3 offshore crane vessels in production since 2019, the principal component is depreciated over a period of 20 years and a second component is amortised over a period of 10 years. For major jack-up vessels this depreciation rule was already applicable. The principal component mainly includes the hull and machinery and the second component relates to parts of a vessel for which the lifespan is shorter than the economic life cycle of the vessel. Furniture and other fixed assets are depreciated over a period between 3 and 10 years.

For all equipment with a residual value, this amount has been estimated as 1% of the investment value from 2019 onwards. The estimated useful lives, residual values and depreciation methods are reviewed at each year end, also considering the potential impact of climate change. Any changes in estimates are accounted for prospectively.

Property, plant and equipment under construction are included based on the instalments paid and the capitalised interests during the construction period.

Gains and losses on disposals are determined by comparing the net disposal proceeds with the carrying amount and are recognised within other operating income or other operating expenses.

The Group as lessee, right-of-use assets and lease liabilities

The Group as lessee

The Group assesses at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

The Group applies a single recognition and measurement approach for all leases, except for short-term leases (less than one year) and leases of low-value assets.

Right-of-use assets and lease liabilities

Assets, representing the right to use the underlying leased asset, are capitalised as right-of-use assets at cost, comprising the amount of the initial measurement of lease liability, any lease payments made at or before the commencement date less any lease incentives received, any initial direct costs and restoration costs. The corresponding lease liabilities, representing the net present value of the lease payments to be made over the lease term, are recognised as long-term or current liabilities depending on the period in which they are due. The lease payments are discounted using the lessee's incremental borrowing rate. The lease payments include fixed payments (including in-substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease liabilities are included in interest-bearing debt. Lease interest is charged to the income statement as an interest expense. Leased assets are depreciated, using straight-line depreciation over the shorter of the lease term and the estimated useful life of the assets, including the period of renewable options, in case it is reasonably certain that the option will be exercised. When there is reasonable certainty that ownership will be obtained by the end of the lease term, the depreciation policy for the leased asset is consistent with that for depreciable assets which are owned. However, when there is no reasonable certainty that ownership will be obtained by the end of the lease term, the asset is depreciated over the shorter of the lease term and its expected useful life. The right-of-use assets are also subject to impairment.

Intangible assets

Acquired concessions, patents, licences and similar rights These intangibles, that are separately acquired and that have a finite useful life, are carried at cost less accumulated amortisation and accumulated impairment losses. Amortisation is recognised on a straight line basis over their estimated useful lives. These intangibles mainly relate to the acquired technology of the SPT Offshore business that is amortised over the economic lifetime of 10 years.

Costs for configuring or customising a supplier's application software in a Software as a Service (SaaS) arrangement is determined as a service contract and expensed.

Research and development

Expenditure on research activities is recognised in the income statement as an OpEx expense as incurred.

An internally-generated intangible asset arising from development (or from the development phase of an internal project) is recognised if, and only if, all of the following have been demonstrated:

• the technical feasibility of completing the intangible asset so that it will be available for use or sale
• the intention to complete the intangible asset and use or sell it
• the ability to use or sell the intangible asset
• how the intangible asset will generate probable future economic benefits
• the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset
• the ability to reliably measure the expenditure attributable to the intangible asset during its development

The amount initially recognised for internally-generated intangible assets is the sum of the expenditure incurred from the date when the intangible asset first meets the recognition criteria listed above. Where no internally- generated intangible asset can be recognised, development expenditure is recognised in profit or loss in the period in which it is incurred.

Subsequent to initialrecognition, internally-generated intangible assets are reported at cost less accumulated amortisation and accumulated impairment losses, on the same basis as intangible assets that are acquired separately. Impairment testing is done during the development at each closing period.

In the segment Concessions, some development expenses are capitalised in the associates DEME Concessions participates in, as well as in the participating entity itself that is fully consolidated. For each project, initial recognition has to be approved by the Audit Committee and impairment testing is discussed in the meeting on a semi-annual basis.

Exploration for and evaluation of mineral resources

In the segment Concessions, DEME expenses costs incurred for the exploration and evaluation of mineral resources on the seabed since the recognition criteria are not met.

Goodwill

Goodwill arising from a business combination is recognised as an asset on the date on which control was obtained (the acquisition date). Goodwill is measured at cost being the excess of the consideration transferred, the non-controlling interests in the acquired company and the fair value of the stake already owned by the Group in the acquired company (if any) over the net amount of identifiable assets acquired and liabilities assumed on the acquisition date.

Non-controlling interests are initially measured either at fair value, or at the non-controlling interests' share of the acquiree's recognised identifiable net assets. The basis of measurement is selected on a transaction by transaction basis.

If, after reassessment, the net balance, at the acquisition date, of identifiable assets acquired and liabilities assumed is higher than the sum of the consideration transferred, non-controlling interests in the acquiree and the fair value of the stake in the acquiree previously owned by the Group (if any), the surplus is recognised immediately in the income statement as a gain from a bargain purchase.

Goodwill is not amortised but is subject to impairment tests taking place annually or more frequently if there is an indication that the cash-generating unit to which it is allocated could have suffered a loss of value.

Goodwill is stated on the balance sheet at cost less accumulated impairment losses, if any. Impairment of goodwill is not reversed in future periods.

If the Group loses control over a subsidiary, it derecognises the related assets (including goodwill), liabilities, non-controlling interest and other components of equity, while any resultant gain or loss is recognised in profit or loss. Any investment retained is recognised at fair value.

Impairment tangible and intangible assets including goodwill

At the end of each reporting period, the Group reviews the carrying amounts of its property, plant and equipment and right-of-use assets and intangible assets to determine whether there is any indication of impairment. If such indication exists or when it is required, the asset's recoverable amount is estimated. For intangible assets that are not yet available for use, and for goodwill, the recoverable amount is estimated at each balance sheet date. An impairment loss is recognised whenever the carrying amount of an asset orits cash-generating unit exceeds its recoverable amount. Recoverable amount is the higher of fair value less costs of disposal and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognised immediately in the income statement.

When there is an indication that prior recognition impairment losses no longer exist, the carrying amount of the asset (or a cashgenerating unit) is increased to the revised estimate of its recoverable amount, but in such a way that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognised immediately in the income statement. An impairment loss on goodwill is never reversed.

Provisions

Provisions are recognised in the balance sheet when the Group has a presented obligation (legal or constructive) resulting from a past event, when it is probable (more likely than not) that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate of the amount of the obligation can be made.

The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. When a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows (when the effect of the time value of money is material).

The unwinding of discount on provisions is recognised as a financial expense.

Warranty provisions

Provisions for warranties are recognised based on the best estimate of the expected cash outflows or cost of repair to settle contractually agreed warranties during the defect notification period for completed projects. The carrying amount of these provisions is estimated based on common industry practice and the Group's experience with warranty claims for relevant projects. Initial recognition of these assurance-type warranties is based on historical experience and the estimate of warranty-related costs is revised annually.

Restructuring provisions

Restructuring provisions will be recognised when the Group has a constructive obligation, meaning when there is a detailed formal plan that identifies the business or part of the business concerned, the location and number of employees affected, the detailed estimate of the associated costs and the timeline. The Group must also notify all the employees affected about this plan's main features.

Other provisions

Other provisions, more specifically in the Environmental segment, relate to the legal provision for the capping of the landfill when the dumping areas are full or to the provision for end of contract reinstatement of a site. Other provisions can also be provisions for legal proceedings.

Retirement benefit obligations

Defined contribution plans without interest guarantee by the employer

Contributions to defined contribution plans are recognised as an expense in the income statement when incurred.

Belgian defined contribution plans with interest guarantee by the employer

By law, defined contribution pension plans in Belgium are subject to minimum guaranteed rates of return. Consequently, these 'defined contribution' plans classify as 'defined benefit' plans.

Defined benefit plans

For defined benefit retirement benefit plans, the cost of providing benefits is determined using the projected unit credit method, with actuarial valuations being carried out at the end of each annual reporting period. Remeasurement, comprising actuarial gains and losses, the effect of the changes to the asset ceiling (if applicable) and the return on plan assets (excluding net interest), is reflected immediately in the statement of financial position with a charge or credit recognised in other comprehensive income in the period in which they occur. Remeasurement recognised in other comprehensive income is reflected as a separate reserve in equity and will not be reclassified to profit or loss. Past service cost is recognised in profit or loss in the period of a plan amendment. Net interest is calculated by applying the discount rate at the beginning of the period to the net defined benefit liability or asset.

Inventories

Inventories are measured at the lower of cost and net realisable value.

The weighted average cost method is used to calculate the cost for raw materials, whereas the cost of consumables is determined using the FIFO method.

Net realisable value is the estimated selling price in the ordinary course of business, less the costs of completion and estimated costs to make the sale.

When inventories are sold, the carrying amount of those inventories shall be recognised as an expense in the period in which the related revenue is recognised. The amount of any write down of inventories to net realisable value and all losses of inventories shall be recognised as an expense in the period the write down or loss occurs.

The amount of any reversal of any write down of inventories, arising from an increase in net realisable value, shall be recognised as a reduction in the amount of inventories recognised as an expense in the period in which the reversal occurs.

Contract assets and contract liabilities

Contract assets concern the gross amount yet to be charged which is expected to be received from customers for contractual work performed up to the reporting date (hereinafter: "work in progress") and services rendered. Work in progress is valued as the sum of the cost price of the work performed, plus a part of the expected results upon completion of the project in proportion to the progress made and less progress billings, and less potential provisions for losses. Provisions are recognised for expected losses on work in progress as soon as they are anticipated and if applicable, any profits already recognised are reversed. As long as the project is not started and the assumptions regarding execution of the work are not final yet (hence a loss to completion provision is difficult to measure reliably), no loss to completion provision is accounted for, unless there is a certain event supporting the provision. A loss to completion provision is accounted for as a contract liability. Revenues for additional work and claims are included in the overall contract revenues if the client has accepted the sum involved. The cost price includes project costs, consisting of payroll costs, materials, costs of subcontracted work, rental charges and maintenance costs of the equipment used and other project costs. The vessel rates used are based on the expected average vessel occupation in the long run. The progress of a project is measured as the ratio of the basis of the cost of the work performed in relation to the total expected cost price of the project as a whole. Profits are not recognised unless a reliable estimate of the end of project result can be made. DEME considers that no such reliable estimate can be made as long as the percentage of completion remains below 10% of the total expected cost price of the project or if the installation vessels for offshore wind farm foundation projects has not yet been mobilised. The balance of the value of work in progress is determined per project.

For projects where the progress billings and advance payments exceed the value of work in progress, the balance is recognised under contract liabilities instead of under contract assets. Advances are amounts received by the Group (no significant financing component) before the related work is performed. The Group presents those separately from other contract liabilities.

Trade and other operating receivables

Trade and other operating receivables are stated initially at fair value and subsequently at amortised cost less accumulated impairment losses.

Assets held for sale

The Group classifies non-current assets as held for sale if their carrying amounts will be recovered principally through a sale transaction rather than through continuing use. Non-current assets classified as held for sale are measured at the lower of their carrying amount and fair value less costs to sell. Costs to sell are the incremental costs directly attributable to the disposal of an asset, excluding finance costs and income tax expense.

The criteria for held for sale classification is regarded as met only when the sale is highly probable, and the asset is available for immediate sale in its present condition. Actions required to complete the sale should indicate that it is unlikely that significant changes to the sale will be made or that the decision to sell will be withdrawn. Management must be committed to the plan to sell the asset and the sale expected to be completed within one year from the date of the classification.

Property, plant and equipment and intangible assets are not depreciated or amortised once classified as held for sale.

Assets and liabilities classified as held for sale are presented separately as current items in the statement of financial position.

Cash and cash equivalents

Cash and cash equivalents consist of cash in hand and on bank accounts and short-term investments with an initial term of less than three months. Cash, cash equivalents and short-term deposits are carried in the balance sheet at nominal value.

If the possible outcomes are binary or concentrated to one value, the uncertain tax position is measured using the most likely amount. In case there exists a range of possible outcomes that are neither binary nor concentrated on one value, the sum of the weighted amounts in a range of possible outcomes might best predict the resolution of the uncertainty.

Investment tax credits

Investment tax credits are excluded from the scope of IAS 12 income taxes and IAS 20 accounting for government grants and disclosure of government assistance. In accordance with IAS 8 accounting policies, changes in accounting estimates and errors, the Group defined an accounting policy in respect of investment tax credits by making an analogy to IAS 12 income taxes. By making this analogy and when the entity satisfies the criteria to receive the credit, this will be recognised in the income statement (deferred taxes), and the related assets in the statement of financial position (deferred tax asset).

Risks from financial instruments

The Group's financial instruments are cash and cash equivalents, trade and other receivables, interest- bearing loans, trade and other payables and derivatives. Derivatives are used exclusively as hedging instruments and not for trading or other speculative purposes.

The Group is exposed to the following risks from financial instruments which will be further elaborated in note (21):

• credit and counterparty risk
• liquidity risk
• market risk consisting of currency risk, interest rate risk and price risks

Derivate financial instruments and hedging

The company uses derivative financial instruments primarily to reduce exposure to adverse fluctuations in interest rates, foreign exchange rates, commodity prices and other market risks. As already mentioned above, the Group's policy prohibits the use of derivatives for speculation. The company does not hold or issue derivative financial instruments for trading purposes. However, derivatives which do not qualify as hedging instruments as defined by IFRS 9 are presented as instruments held for trading. Derivative financial instruments are recognised initially at cost. Subsequent to initial recognition, derivative financial instruments are measured at fair value. Recognition of any resulting unrealised gain or loss depends on the nature of the derivative and the effectiveness of the hedge. The fair value of interest-rate swaps is the estimated amount that the company would receive or pay when exercising the swaps at the closing date, taking into account current interest rates and the solvency of the swap counterparty. The fair value of a forward-exchange contract is the quoted value at the closing date, and therefore the present value of the quoted forward price.

Hedge accounting is applicable if all criteria in the IFRS 9 standard are fulfilled:

• there is formal designation and documentation for the hedging relationship at the inception of this relationship
• the economic relationship between the hedged item and the hedging
• instrument and the potential sources of ineffectiveness must be documented
• the retrospective ineffectiveness must be assessed at each closing

Variations of fair value between periods are recognised differently according to the accounting classification.

Cash flow hedges

When a derivative financial instrument hedges variations in cash flows relating to a recognised liability, a firm commitment or an expected transaction, the effective part of any gain or loss resulting from the derivative financial instrument is recognised directly in other elements of the comprehensive income and is presented in a separate reserve in equity. When the firm commitment or the expected transaction results in the recognition of an asset or liability, the cumulative gain or loss is removed from the comprehensive income and is reported under a separate reserve in the equity. Otherwise, the cumulative gain or loss is removed from equity and recognised in the income statement at the same time as the hedged transaction. The ineffective part of any gain or loss on the financial instrument is taken into result. Gains or losses resulting from the time value of derivative financial instruments are recognised in the income statement. When a hedging instrument or hedge relationship expires but the hedged transaction is still expected to occur, the cumulative unrealised gain orloss (at that point) remains in equity and is recognised in accordance with the above policy when the transaction occurs. If the hedged transaction is expected not to occur, the cumulative unrealised gain or loss recognised in equity is immediately taken to income.

Fair value hedges

When a derivative financial instrument hedges variations in the fair value of a recognised receivable or payable, any gain or loss resulting from the remeasurement of the hedging instrument is recognised in the income statement. The hedged item is also stated at the fair value attributable to the risk hedged, with any gain or loss being recognised in the income statement. The fair value of hedged items, in respect of the risk hedged, is their carrying amount at the balance sheet date translated into euro at the exchange rate on that date.

Defined benefit costs are categorised as follows:

• service cost (including current service cost, past service cost, as well as gains and losses on curtailments and settlements)
• net interest expense or income
• remeasurement

The Group presents the first two components of defined benefit costs in profit or loss. Curtailment gains and losses are accounted for as past service costs.

The retirement benefit obligation recognised in the consolidated statement of financial position represents the actual deficit or surplus in the Group's defined benefit plans. Any surplus resulting from this calculation is limited to the present value of any economic benefits available in the form of refunds from the plans or reductions in future contributions to the plans.

Interest-bearing loans and borrowings

Interest-bearing loans and borrowings are recognised initially at fair value adjusted for the attributable transaction costs. Subsequent to initial recognition, interest-bearing loans and borrowings are stated at amortised cost with any difference between the proceeds (adjusted for transaction costs) and redemption value being recognised in the income statement over the period of the loan or borrowings on an effective interest rate basis.

The effective interest method is a method of calculating the amortised cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments (including all fees and points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the financial liability, or (where appropriate) a shorter period, to the amortised cost of a financial liability.

Trade and other payables

Trade and other payables are stated at amortised cost. Invoices and related payment terms depend on individual contractual terms with suppliers.

Income taxes

Income taxes are classified as either current or deferred taxes. Income tax is recognised in the income statement except to the extent that it relates to items recognised directly in other comprehensive income (OCI) or equity, in which case it is recognised in OCI or equity.

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities.

Current income taxes include expected tax charges based on the accounting profit for the current year and adjustments to tax charges of prior years. Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at the reporting date in the countries where the Group operates and generates taxable income.

Deferred taxes are calculated using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. The principal temporary differences arise from depreciation of property, plant and equipment, provisions for defined benefit plans, fair value measurement of derivatives and tax losses carried forward.

Deferred taxes are measured using the tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be realised or settled, based on tax rates enacted or substantively enacted by the balance sheet date. A deferred tax asset shall be recognised for the carryforward of the unused tax losses and unused tax credits to the extent that it is probable that future taxable profit will be available against which the unused tax losses and unused tax credits can be utilized. Deferred tax assets are recognised for all deductible temporary differences to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilised unless the deferred tax assets arise from the initial recognition of an asset or liability in a transaction that is not a business combination and at the time of the transaction affects neither accounting profit nor taxable profit (tax loss). Deferred tax assets are also recognised for all deductible differences arising from investments in subsidiaries, joint ventures and associates to the extent that, it is probable that the temporary difference will reverse in the foreseeable future and the taxable profit will be available against which the temporary difference can be utilised. At each balance sheet date, the Group reassess if all the above criteria are met.

IFRIC 23, which became effective as from 1 January 2019 onwards, clarifies how to apply the recognition and measurement requirements in IAS 12 income taxes when an uncertainty over current and deferred income tax treatments exists. The acceptability of a particular tax treatment under tax law may not be known until the relevant taxation authority or a court takes a decision in the future. In assessing whether and how an uncertain tax treatment affects the determination of taxable results, the Group assumes that a taxation authority will examine amounts it has a right to examine and has full knowledge of all related information when making those examinations. If the Group concludes it is probable that the taxation authority will accept an uncertain tax treatment, it determines the taxable result consistently with the tax treatment used or planned to be used in its income tax filings. If the Group concludes that it is not probable that a taxation authority will accept an uncertain tax treatment, it reflects the effect of uncertainty in determining its accounting tax position.

Other operating income

Other operating income includes the gain on sale of intangible assets, the gain on sale of property, plant and equipment as well as the gain on sale of financial assets, next to other non-recurring income.

The latter includes the insurance income received with respect to damages to our vessels and equipment, as well as liquidated damages received in the context of a construction contract of new equipment only if it compensates incremental charges incurred due to late delivery of the new equipment.

Operating expenses

Raw materials, consumables, services and subcontracted work

This category in the consolidated statement of income is the OpEx of the Group. All operating expenses (also SG&A expenses incurred through our normal business operations) are included except for personnel expenses, depreciation, amortisation and impairment costs and other operating expenses that are disclosed in a separate note.

Research and development, advertising and promotional costs and IT systems development costs

Research, advertising and promotional costs are expensed in the year in which they are incurred. Development costs and IT systems development costs are expensed in the year in which they are incurred if they do not meet the criteria for capitalisation. These costs are included in the operating expenses (OpEx) of the Group.

Other operating expenses

Other operating expenses include the loss on sale of intangible assets and the loss on sale of property, plant and equipment. The non-cash movements in amounts written off inventories and trade receivables, in retirement benefit obligations and in provisions is also recorded as other operating expenses. Next to above, other costs such as various taxes, import and stamp duties are also included in other operating expenses.

Financial result

Interest income is accrued on a time basis, by reference to the principal outstanding and at the effective interest rate applicable.

All interest expenses and other costs incurred in connection with borrowings, except those which were eligible to be capitalised, are expensed. The interest expense is recognised in the income statement using the effective interest rate method.

Interest income and interest expense also include gains or losses resulting from the time value of derivative financial instruments.

Dividend income (from non-consolidated participations) is recognised when the shareholder's right to receive payment has been established (provided that it is probable that the economic benefits will flow to the Group and the amount of income can be reliably measured).

Other financial expenses, included in the other financial result, mainly relate to costs incurred for project related bank guarantees.

Instruments related to construction contracts

If a derivative financial instrument hedges variations in cash flows relating to a recognised liability, a firm commitment or an expected transaction in the framework of a construction contract (mainly forward purchases of raw materials, or foreign exchange purchases or sales), a documentation of the cash flow hedge relationship as described above will not be prepared. Any gain or loss resulting from the derivative financial instrument is recognised in the income statement. These instruments are, however, submitted to a test of efficiency based on the same methodology as utilised for hedge accounting. The effective part of any gain or loss on the financial instrument is considered as construction cost and is presented as an operational result based upon the percentage of completion of the contract. The fair value variation itself however is not considered for determining the percentage of completion of the contract and deferred hedge charges and income are not part of contract assets or contract liabilities as these are stated at hedge rate and not at market rate. Deferred hedge charges and income are included in other current assets and other current liabilities.

Revenues

Turnover or revenue from contracts with customers All segments, except for the Concessions segment, which

is the Group's investment and development vehicle, are contributing to the Group's turnover.

Consolidated revenue comprises the total of the work and services realised by DEME and its subsidiaries pursuing their main activity.

DEME's activities encompass dredging, land reclamation, hydraulic engineering, construction and services for the offshore oil & gas and renewable energy industries, civil engineering and environmental works. These activities being construction or execution of a service are executed following a contract with the customer.

The consolidated revenue is recognised in accordance with IFRS 15. Revenues don't have any significant financing component. Most construction and service contracts with the customers involve only one performance obligation, which is fulfilled progressively over time. For a limited number of "EPCI" contracts in the renewable business (offshore wind farms), multiple performance obligations were identified. In those contracts the EPC and T&I part for the monopiles can be separated, as well as the cable laying part and the EPC and T&I part for the offshore substations (OSS). Those parts of the contract are capable of being distinct, and are distinct in the context of the contract, and accordingly are considered as separate performance obligations.

Where a contract includes several distinct performance obligations, the Group allocates the overall price of the contract to each performance obligation in accordance with IFRS 15. That price corresponds to the amount of the consideration to which it expects to be entitled. The most common variable considerations such as the steel price, fuel consumption or design price modifications shall only be included in the transaction price to the extent that it is highly probable that a significant reversal in the revenue recognised will not occur. When the price includes a variable component, such as a performance bonus or a claim, the Group only recognises that consideration from the moment that agreement is reached with the client (virtually certain).

There are no IFRS 15 service-type warranties.

The Group has concluded that revenue from construction and service contracts should be recognised over time. As such, the revenue recognition reflects the rate at which our performance obligations are fulfilled corresponding to the transfer of control of a good or service to our customers. When there is no transfer of control throughout the contract revenue is still recognised over time, based on the fact that the asset created has no alternative use, as well as the fact that an enforceable right to payment exists for performance completed to date.

Revenue from construction and service contracts is recognised by reference to the stage of completion of the contract activity at the end of the reporting period, measured based on the proportion of contract costs incurred for work performed to date relative to the estimated total contract costs, except where this would not be representative of the stage of completion. A correction is made for the cost of material (e.g. steel) that is purchased but not yet manufactured or utilised in the production process at the reporting date. When the outcome of a construction contract cannot be estimated reliably, contract revenue is recognised to the extent of project costs incurred that will probably be recoverable. Project costs are recognised as expenses in the period in which they are incurred. Management concluded that costs to fulfil a contract that are not incurred in respect of the satisfaction of the performance obligation have no material impact on the recognition of revenues and margin of the project. As such, these costs are also recognised when incurred and are included computing the stage of completion. When it is probable that total contract costs will exceed total contract revenue, the expected loss is recognised as an expense immediately, based upon the principles of IAS 37 provisions, contingent liabilities and contingent assets for onerous contracts at the best estimate of the expenditure required to settle the obligation. As such the expected loss to record will reflect management expectations about the costs of satisfying the obligation less the amount to be received from the customer (more probable than not).

When there are major constraints on transferring cash from the working country to the head office, the profit on a contract is only recognised on a cash basis.

The percentage of shareholding in or the consolidation method of the following subsidiary and associate changed in the course of 2022:

Subsidiary:

• Dragafi Asia Pacific Pte Ltd (Singapore) and its subsidiary, within Dredging & Infra, from 40% to 100% and from equity method consolidation to full consolidation

Associate:

• Thistle Wind Partners Ltd (United Kingdom), within Concessions, from 100% to 42.50% and from fully consolidation to equity method consolidation

The shares in Filterres SA (Belgium) (74.90%), within the Environmental segment, were sold in the course of 2022 to the partner in the company. The same applied for Hydrogeo SARL (Morocco) (40%), a dormant company in the Offshore Energy segment. In 2022, Seatec Holding BV and its 100% affiliate Seatec Subsea Systems BV, within the Offshore segment, were externally sold.

List of the Group's subsidiaries, joint ventures and associates

The classification to one or another 'operational segment' of a company within the Group can vary each year based upon the projects performed by that company and is not necessarily the same as the operational segment of its legal parent company. A company can also execute projects for more than one operational segment. In that case the main operational segment for the current year is disclosed in the table below.

All subsidiaries, joint ventures and associates have the same yearend closing date as at 31 December, except for those in India and Zeeboerderij Westdiep BV (Belgium) where the year-end closing date is 31 March. When the year-end closing date differs from the 31 December closing date, the figures included in the consolidation are those for the period ended 31 December calendar date.

Further on, within the DEME Group there are no significant restrictions to transfer funds in the form of cash and dividends.

The changes in consolidation scope described above have no material impact on the financial statements.

The percentage of shareholding in the following subsidiaries changed during 2023:

• Global Sea Mineral Resources NV (GSR) (Belgium) and its 100% affiliate Deeptech NV (Belgium), within Concessions, from 100% to 84.3%

The Group has entered into a strategic cooperation with Transocean Ltd (NYSE: RIG), a global leader in the offshore drilling industry. This cooperation brings together the leadership of GSR in ultra-deepwater mineral exploration and seafloor nodule collection technology with Transocean's world-class offshore expertise and capabilities.

As part of its investment, Transocean Ltd contributed the ultradeepwater drilling vessel 'Ocean Rig Olympia', valued at 85 million USD, for GSR's ongoing exploration work. Next to that, a cash investment of 10 million USD (9.4 million euro) as well as engineering capacity was contributed. In return, Transocean Ltd received a minority stake of 15.7%, including a board seat in GSR.

To become fully operational, the entity needs to obtain a license to operate. GSR is in the process of obtaining such license and at the moment of issuance of this report, there is no indication that the license would not be granted.

As the change in GSR's ownership does not imply losing control, the transaction has been accounted for as an equity transaction with non-controlling interest (NCI), resulting in the following:

(in millions of euro)

Assets contributed in GSR	89.1
Net assets attributable to NCI	-20.4
Increase in equity attributable to the parent	68.7
Represented by
Increase in retained earnings	68.7

Subsidiaries (fully consolidated)

For the year ended 31 December

Until 29 June 2022, Dredging, Environmental & Marine Engineering NV (DEME NV), was the parent company of the Group. On that date CFE NV transferred its 100% stake in DEME NV to a newly established company, DEME Group NV, by means of a partial demerger and as such DEME Group NV became the new parent company. DEME NV, as a subholding, is now included in the list as a subsidiary. Reference is made to note (17) share capital, dividends and reserves for more information.

DEME Environmental NV, the parent company of the Environmental segment, is partially owned (25.10%) by a third party. In the Dredging & Infra segment, particularly in the maritime services business, Combined Marine Terminal Operations Worldwide NV (CTOW) and its affiliates are owned for 45.62 % by third parties.

Comparative financial statement analysis

This section should be read together with '01. Introduction- Group performance 2023' earlier in this Annual Report, in which the primary contributors to the result of the year are explained. Within '01. Introduction- Group Performance 2023', when discussing segment performance individually, and within the segment reporting, figures from the management report are utilised. The only reconciling item between these figures and the figures as in the financial statements is the impact of the different consolidation method for joint ventures. Joint ventures are consolidated proportionally in the management report figures, whereas according to equity method in the financial statements. The result for the period (Share of the Group) is not affected by the difference in consolidation method, only the presentation is different.

In both the explanatory notes and comparative financial statement analysis, the figures as per financial statements are disclosed.

Business combinations in the course of 2023 and 2022

Business combinations in the course of 2023 There were no business combinations in 2023.

The Group has entered into a strategic cooperation with Transocean Ltd (NYSE: RIG), a global leader in the offshore drilling industry. As part of its investment, Transocean Ltd contributed the ultra-deepwater drilling vessel 'Ocean Rig Olympia', valued at 85 million USD, for GSR's ongoing exploration work. Next to that, a cash investment of 10 million USD (9.4 million euro) as well as engineering capacity was contributed. In return, Transocean Ltd received a minority stake of 15.7%, including a board seat in GSR.

Business combinations and disposals in the course of 2022 There were no business combinations in 2022.

Within the Offshore segment the company Seatec Holding BV and its affiliate Seatec Subsea Systems BV were sold as part of a management buyout. This sale had an immaterial impact on the financial statements. The manufacturing and trading vehicle Seatec was acquired in 2020 as part of the SPT Offshore Group. DEME secured exclusivity on the suction pump equipment manufacturing executed by Seatec through a framework agreement.

The shares in Filterres SA (Belgium) (74.90%), within the Environmental segment, were sold in the course of 2022 to the partner in the company. The same applied for Hydrogeo SARL (Morocco) (40%), a dormant company in the Offshore Energy segment. These sales had a very immaterial impact on the financial statements.

The higher operational activity in 2023 together with continued substantial investments explain the increase of 250.3 million euro of total assets. The net rise of property, plant and equipment amounts to 160.2 million euro whereas the increased activity is reflected in higher contract assets (+288.3 million euro) and trade and other operating receivables (+44.5 million euro). Although there is a positive free cash flow after dividend payment of 22.8 million euro this year, cash and cash equivalents decrease with 133.2 million euro after a net decrease or repayment of 154.1 million euro interest-bearing debt (excl. the impact of IFRS 16 leasing).

The decrease in investments in joint ventures and associates of 32.4 million euro is mainly related to dividend payments for an amount of 27.8 million euro, alongside a decrease in the fair value of interest-rate hedges amounting to 14.2 million euro offset by a result of the year of 3.2 million euro and capital increases totalling 8.6 million euro. The fair value of interest-rate hedges of fully consolidated entities also declined, explaining the decrease within both non-current and current financial derivatives and particularly the interest rate swaps.

Assets held for sale decreased with 30.4 million euro. In 2022 the corresponded to the net book value of the 'Groenewind', a vessel within the Offshore Energy segment, that was sold in July 2023. In 2023 the amount recorded as asset held for sale is related to the reclassification of the net book value of the workshop in Zeebrugge that will be sold in 2024.

Total revenues increased by 633.3 million euro in 2023. Turnover surged by 630.7 million euro, marking a 23.8% increase compared to 2022, reaching a milestone amount of 3,285.4 million euro and even surpassing 3 billion euro for the first time in DEME Group's history. Other operating income remained consistent with the previous year. The amount of 2023 includes 18.6 million gain on sale of property, plant and equipment, amongst others for the sale of the 'Groenewind' (2022: 7.8 million gain on sale of equipment). Additionally, certain material insurance claim refunds are accounted for in other operating income for 2023. In 2022, liquidated damages for an amount of 18.8 million euro were received as compensation for the incremental costs incurred as a result of a delayed delivery of installation vessel 'Orion' (Offshore Energy segment).

Operating result or EBIT increased with 86.0 million euro primarily due to the significant increase in turnover but also as the result of an increase in the EBIT margin itself, rising to 7.3% from 5.8% last year. Depreciations and impairment expenses increased to 355.2 million euro compared to 318.7 million euro in 2022. The higher level of depreciation costs in 2023 is attributable primarily to the investments in 'Orion', DEME's largest offshore installation vessel, that was added to the fleet mid-2022, and in 'Viking Neptun', a cable laying vessel that was integrated into the fleet in the first half of 2023. The amount also includes 13.1 million euro impairment cost for 'Al Jarraf', one of DEME's cutter suction dredger vessels. Other operating expenses decreased with 5.7 million euro and will be further explained in the note (2) other operating income and expenses.

Financial result amounts to -23.3 million euro which is 1 million euro less negative than the financial result of last year ( -24.3 million euro). The increase in net interest expenses this year is compensated by less negative foreign currency translation effects and more other financial income.

Result before taxes is 87.1 million euro higher compared to last year. Effective tax rate reduced from 24.0% last year to 22.8% this year.

Share of profit of joint ventures and associates decreased with 12.6 million euro despite a high contribution of associates from the Concessions segment with an amount of 37.4 million euro. This positive contribution was partially offset by DEME's Taiwanese offshore joint venture company that absorbed project losses on the Zhong Neng project in Taiwan. Amounts attributable to noncontrolling interests increased with 6.2 million euro following the increased activity and profitability of the Environmental segment.

Result for the period (Share of the Group)rose by 50.0 million euro compared to previous year, reaching 162.8 million euro, equivalent to 6.43 euro per share.

Total liabilities, current and non-current, increased with 65.7 million euro.

Group equity rose by 184.5 million euro, boosted by the result of the year of 162.8 million euro. In addition, a positive impact of 68.7 million euro was attributed to the step-in of a strategic partner in Global Sea Mineral Resources NV, accounted for as an equity transaction affecting both Group equity and non-controlling interests (+ 20.4 million euro). Reference is made to section group structure and changes in the reporting period. On the other hand, the other comprehensive income (hedging reserve, remeasurement on retirement benefit obligations and cumulative translation adjustments) reflects a negative impact of 36.9 million euro together with the dividend payment of 37.9 million euro in 2023.

Non-current liabilities decreased with 179.8 million euro of which 137.4 million euro is related to the decrease in non-current interest-bearing debt as in 2023 no material new loans were raised.

The increase in current liabilities of 245.5 million euro is mainly explained by the increase in contract liabilities (+124.1 million euro) and trade payables (+119.9 million euro) reflecting the higher activity in 2023.

Cash flow from operating activities	Cash flow (used in) / from financial activities

The increase in cash flow from operating activities of 108.7 million euro is compensated by changes in working capital for -91.4 million euro resulting in a net increase of 17.3 million euro related to the Group's operations.

Cash flow (used in) / from investing activities

Despite the continued high level of investments in 2023, totalling 427.1 million euro, cash flow used in investing activities was 129.2 million euro less negative compared to 2022. Total investments decreased with 85.7 million euro whereas cash in from divestments (amongst others the sale of 'Groenewind') increased with 43.4 million euro compared to last year. The amount of investments paid for the acquisition of 'intangible assets' and 'property, plant and equipment' amounts to 398.9 million euro compared to 483.9 million euro at the end of last year.

Cash flow used in financial activities significantly declined from a net cash-in flow of 43.2 million euro in 2022 to a net cash-out flow of 225.3 million euro. This decrease accounts for the reduction in cash and cash equivalents by 133.2 million euro in 2023.

The sum of cash flow from operating activities and investing activities amounts to 93.9 million euro. After deducting 32.3 million euro lease repayments in 2023 (2022: 27.9 million euro) that are included in repayment of interest-bearing debt but that are considered to be operational cash-out flow, the free cash flow totals 61.6 million euro (cash surplus) compared to -80.4 million euro (cash shortage) last year.

Total turnover as per financial statements	3,285,422	2,654,725

(*) A geographical market is determined as the area (location) where projects are realised and services are provided or the project location for offshore works.

DEME's geographic expansion strategy is well represented in the geographical breakdown of the turnover, with strong growth in the Americas region, the Middle East and Asia. The European market grew at a more moderate pace and represented 63% of the global turnover in 2023 compared to approximately 75% in previous years, yet it remains clearly DEME's core region.

Similar to last year, there are no clients contributing more than 10% in the FY Group's turnover. Moreover, as a result of the occasional nature and spread of the contracts, none of the DEME clients structurally will ever qualify as a material client in relation to the total turnover of the Group.

Additionally, based on the current interpretation of the rules regarding the EU Taxonomy and as elaborated in chapter'04. Sustainability' of this Annual Report, DEME's eligible activities expanded in 2023 beyond offshore wind and rail infrastructure to now also include parts of DEME's environmental activities, such as remediation of contaminated sites and soil and sediment management. They are all DEME's activities making a substantial contribution to climate change mitigation. As a result of this expanded scope and stronger growth in eligible activities, 42% of the total turnover can now be considered as taxonomy-eligible turnover compared to 29% a year ago. Further on, 33% of total DEME turnover is now qualified as aligned compared to 26% last year.

Orderbook

The Group's orderbook is the contract value of assignments acquired as of 31 December but that is not yet accounted for as turnover because of non-completion. The orderbook also includes the Group's share in the orderbook of joint ventures, but not of associates.

Contracts are not included in the orderbook until the agreement with the client is signed. A letter of award is not sufficient to include the contract in the orderbook according to the Group's policy. In addition, financial close must be reached when projects will be executed in 'uncertain' countries before including them in the orderbook. 'Uncertain countries' are identified at the discretion of the Executive Committee.

Further on, experience shows that once an agreement has been reached, cancellations or substantial reductions in the scope or size of contracts are quite rare, but they do occur, certainly in markets that are under severe pressure.

The Group's orderbook increased 22% reaching a level of 7,582 million euro compared to 6,190 million euro in 2022. The overall orderbook at year-end was 2.2 times the 2023 turnover. The year-over-year increase was driven by continued strong demand and double-digit growth in all contracting segments.

Noteworthy additions in 2023 included for the Offshore Energy segment are the projects of Île d'Yeu and Noirmoutiers and Dieppe le Tréport in France, Baltic Power in Poland and Greater Changhua in Taiwan and for Dredging & Infra the Princess Elisabeth Island in Belgium, large dredging works in Abu Dhabi and the Oxagon phase 2 project in Saudi Arabia.

Explanatory notes to the consolidated financial statements

Note 1 – Turnover and orderbook

For the year ended 31 December

Turnover

A break-down of the DEME turnover by nature, segment and geographical market can be found below.

Turnover by nature (in thousands of euro)	2023	2022
Revenue from contracts with customers	3,268,156	2,644,257
Revenue from ancillary activities	17,266	10,468
Total turnover as per financial statements	3,285,422	2,654,725

Revenue from contracts with customers mainly comprises the net revenue from the operational activities of the segments. For most contracting activities the contract is based on a fixed/lump sum price. The Group can act both as contractor and principal of an engagement.

Revenue from ancillary activities is revenue that can be very divers such as sale of equipment or fees. It is turnover that is not followed up as a separate project in the management reporting system.

The Group has determined that the disaggregation of revenue by product line is best reflected by the revenue information that is disclosed for each reportable segment under IFRS 8, as this information is regularly reviewed by the chief decision makers (see also separate chapter on Segment Reporting) and best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.

Turnover of segments

(in thousands of euro)	2023	2022
Offshore Energy	1,501,551	957,810
Dredging & Infra	1,604,610	1,524,316
Environmental	304,314	206,336
Concessions	4,972	2,214
Total turnover of segments	3,415,447	2,690,676
Reconciliation (*)	-130,025	-35,951
Total turnover as per financial statements	3,285,422	2,654,725

(*) The reconciliation between the segment turnover and the turnover in the consolidated statement of income refers to the turnover of joint ventures. They are consolidated according to the proportionate method in the segment reporting but according to the equity consolidation method (application of IAS 28) in the financial statements.

As a group, DEME achieved a historic milestone by surpassing 3 billion euro in turnover for the first time. The turnover of the Group grew 24% year-over-year fueled by strong growth in Offshore Energy and Environmental of 57% and 48%, respectively.

Notably, Offshore Energy delivered strong turnover growth, accelerating the conversion of orderbook into turnover and starting to leverage its expanded fleet capacity. The Dredging & Infra segment witnessed a boost in activity levels during the second half of the year, overcoming a -4% decline for the first half to a +5% growth over the full year. The Environmental segment sustained positive growth, primarily driven by its strong positioning within an increasingly stringent environmental regulatory landscape.

Note 2 – Other operating income and expenses

For the year ended 31 December

Other operating income

(in thousands of euro/ (-) is expense)	2023	2022
Gain on sale of property, plant and equipment	18,615	7,752
Gain on disposal of financial fixed assets	-	9
Other operating income	40,054	48,310
Total other operating income	58,669	56,071

Total other operating income for 2023 mainly relates to the sale of 'Groenewind' (Offshore Energy segment), that was classified as assets held for sale at 31 December 2022. Sale took place in July 2023. In 2022 the gain on sale of property, plant and equipment was mainly related to the sale of the jack-up installation vessel 'Thor', also within the Offshore Energy segment. Further on, a damage claim for the 'Ambiorix' was received for an amount of 7 million euro. In 2022 delay damages of 18.8 million euro related to the delivery of the vessel 'Orion' (Offshore Energy segment) were included within other operating income.

The net of gain and loss on sale of property, plant and equipment amounts to 18.5 million euro in 2023. This amount is included in the cash flow from divestments.

Other operating expenses

(in thousands of euro/ (-) is income)

(in thousands of euro/ (-) is income)	2023	2022
Loss on disposal of financial fixed assets	-	17
Loss on sale of property, plant and equipment	71	440
Movement in amounts written off inventories and trade receivables	-2,431	-5,428
Movement in retirement benefit obligations	-3,767	505
Movement in provisions	2,541	4,389
Other operating expenses	24,370	26,606
Total other operating expenses	20,784	26,529

Movement in amounts written off inventories and trade receivables for both current and prior year is partially caused by a final write-off of a customer receivable and related bad debt allowance. The allowance recognised as a cost in prior years is reversed within amounts written off for trade receivables, whereas the write-off of the customer is booked as a service cost in the consolidated statement of income, resulting in a zero profit & loss impact for the financial year. The other minor movement in amounts written off for inventories and trade receivables relates to the reversal of allowances for bad debtors that are no longer uncollectable.

Movement in retirement benefit obligations is the non-paid net defined benefit cost (related to the retirement benefit obligations) that is recorded in the statement of income. The defined benefit cost that is paid (contributions from employer) is recorded as pension expenses in the statement of income. Reference is made to note (23) retirement benefit obligations and to note (3) personnel expenses and employment.

Movement in provisions mainly relates to the movement in warranty provisions. Reference is made to note (25) provisions.

Other operating expenses mainly include various taxes, import and stamp duties.

Note 3 – Personnel expenses and employment

For the year ended 31 December

Average number of persons employed during the year

(in FTE)	2023	2022
Employees	3,201	2,985
Workers	2,133	2,168
Total	5,334	5,153

The average headcount reported in this note is based upon the consolidation scope whereby only the average headcount of entities controlled by the Group is included.

Orderbook by segments (in thousands of euro)	2023	2022
Offshore Energy	3,754,649	3,260,909
Dredging & Infra	3,472,387	2,615,713
Environmental	354,724	313,378
Concessions	-	-
Total orderbook	7,581,760	6,190,000

The increase in the Offshore Energy orderbook is fueled by new contract awards, with project deployments over the next several years, including sizeable project-wins such as a cable contract for Baltic Power, DEME's first offshore wind farm project in Poland, contracts in France for the Dieppe Le Tréport, Île d'Yeu and Noirmoutier offshore wind farms and the Greater Changhua contract in Taiwan with the Taiwanese joint-venture CDWE. In the non-renewables in North America, Offshore Energy also added the Cenovus White Rose project in Newfoundland in Canada. These additions to the orderbook largely offset the cancellations of both the Norfolk Boreas and Empire Wind 2 projects received in the course of 2023.

The orderbook of Dredging & Infra increased with 33% to a level of 3,472 million euro. Additions to the 2023 orderbook include the new Princess Elisabeth Island, the world's first energy island, for which the first caissons will be installed in the course of 2024 as well as prolonged maintenance projects in Belgium for the River Scheldt and Belgium seaports. Additionally in Europe, the Dredging & Infra segment capitalised on its presence in Italy and around the Elbe River, resulting in new projects. Other noteworthy wins overseas include contracts in the Indian subcontinent, the Maldives and West-Africa. At the end of the year, a consortium including DEME, was awarded a large contract for the second phase of capital dredging works and construction of the Port of Oxagon in Saudi Arabia.

As of 31 December 2023, the Environmental orderbook stand at 355 million euro, an increase of 13% compared to 313 million euro a year earlier, mainly driven by new contract wins in Belgium and the Netherlands. Of note is the recent win in Feluy in Belgium where a brownfield will be remediated and transformed into an industrial estate in collaboration with public and private partners. Environmental is actively exploring new, targeted opportunities in Italy and the UK, commencing initial environmental study efforts.

Orderbook by geographical market (in thousands of euro)	2023	2022
Europe - EU	3,708,502	2,467,294
Europe - non EU	683,050	898,747
Africa	394,161	306,325
Asia & Oceania	870,099	752,385
America	1,329,957	1,692,695
Indian subcontinent	48,877	68,033
Middle East	547,114	4,521
Total orderbook	7,581,760	6,190,000

From a geographical perspective all regions, except the Americas region, shows solid increases in 2023. While the breakdown illustrates DEME's presence in all geographies, Europe continues to account for more than half of the orderbook. The aforementioned new projects in Abu Dhabi and Saudi Arabia boosted the orderbook for the Middle East region while the orderbook for the Americas moderated after strong orders intake in 2022 and 2021.

Orderbook 2023 split in time (in thousands of euro)	2024	2025	2026	Beyond	Total
Total orderbook	3,692,355	2,650,172	916,088	323,145	7,581,760

Total orderbook	2,307,546	1,612,426	1,448,181	821,847	6,190,000

The Group estimates that 48.7% of the orderbook will be executed in the next year (2022: 37.3%). The execution of the orderbook depends on several factors, such as weather circumstances, soil and technical conditions, vessel availability and a lot of other factors.

	'Concessions, patents and licenses' do not include indefinite useful lives intangible assets.

The 'additions of the year' mainly relate to the capitalisation of development costs in the Concessions segment.

'Amortisation of the year' is recognised under 'depreciation and amortisation expenses' in the consolidated statement of income for an amount of 4.3 million euro. Amortisation of development costs starts at the earliest on the date when financial close of the related project is reached.

The total net book value of 22.8 million euro at the end of the year 2023, includes the intangible assets of the SPT Offshore Group (12.6 million euro) that are amortised over the economic lifetime of 10 years. SPT Offshore Holding BV and affiliates within the Offshore Energy segment was acquired by the Group at the end of 2020.

Personnel expenses (in thousands of euro)	2023	2022
Remuneration	505,674	428,954
Social charges	68,054	61,769
Pension expenses	14,156	15,020
Total	587,884	505,743

Higher payroll expenses compared to last year are the result of an increase in average headcount of 181 FTE together with the automatic indexation of salaries and wages in Belgium as from January 2023 that was notably high due to elevated inflation in 2022.

Note 4 – Financial result

For the year ended 31 December

(in thousands of euro / (-) is cost)	2023	2022
Interest income from other non-current financial assets	1,585	1,511
Time value of financial derivatives	-274	229
Other interest income	6,941	4,286
Total interest income	8,252	6,026
Interest expenses related to borrowings	-19,398	-14,596
Capitalised borrowing cost	1,601	1,467
Time value of financial derivatives	-414	-151
Interest expenses related to lease liabilities	-1,938	-1,634
Total interest expenses	-20,149	-14,914
Realised/unrealised foreign currency translation effects	-9,825	-11,134
Total realised/unrealised foreign currency translation effects	-9,825	-11,134
Other financial income	5,207	2,151
Other financial expenses	-6,754	-6,440
Total other financial result	-1,547	-4,289
Total financial result	-23,269	-24,311

The total financial result of -23.3 million euro is influenced by -9.8 million euro negative foreign currency translation effects. The net exchange rate loss is mainly due to the Group' s operational activities in Egypt (both USD & EGP exchange rate exposure). In 2022, the financial result of -24.3 million euro was also negatively impacted by -11.1 million euro negative foreign currency translation effects (a.o. as a result of the devaluation of EGP).

The increase in total interest expenses is related to a net financial debt that was higher throughout the year in comparison with 2022 and that only in the last quarter of 2023 decreased to a slightly lower level than last year. Although DEME tries to cover the risk of changes in underlying floating interest rates of borrowings through financial derivatives, the impact of rising interest rates besides the level of net financial debt itself, is explaining the increase in total interest expenses as well as total interest income. From the total interest expenses of 20.1 million euro, an amount of 17.5 million euro is interest paid. Reference is also made to the consolidated statement of cash flows.

Total other financial result improved with 2.7 million euro compared to last year, positively impacted by the recognition of delay interests.

Impairment testing of goodwill

In accordance with IAS 36 impairment of assets, goodwill was tested for impairment at 31 December 2023 and 2022. No impairment losses were recognised.

Within the DEME Group, goodwill is tested for impairment annually. The impairment tests are based on figures and insights of the third quarter of the reporting year. If there is an indication that the cash generating unit to which the goodwill is allocated could have suffered a loss of value, impairment testing is done more frequently than once a year. In 2023, there were no such indicators and no additional impairment tests have been prepared.

Significant judgement by management is required to estimate the impact of macroeconomic and other factors on future cash flows, including those related to climate related matters (more detailed in section disclosures related to specific topics). Management does not foresee activities negatively being impacted by climate related business requirements leading to an impairment loss (climate change risk). The Group believes the estimates and assumptions used in the impairment testing are reasonable and are comparable to those that would be used by competitors.

Carrying amount of goodwill

Goodwill is allocated to the cash generating unit that will benefit most of the knowledge acquired upon the acquisition. Management has identified the lowest level of cash generating units based on the most appropriate and most detailed level of information about operations available for internal reporting purposes. The current outstanding goodwill of the DEME Group is allocated as follows:

Carrying amount of goodwill

(in thousands of euro)	2023	2022
CGU Infra	3,536	3,536
CGU Dredging –Asia Pacific	3,024	3,024
CGU Environmental – Ecoterres	2,496	2,496
CGU Offshore	1,943	1,943
CGU Offshore – Foundations	1,256	1,256
CGU Concessions	605	605
CGU Dredging – DBM	168	168
Total	13,028	13,028

The comparison of the carrying amount of each mentioned cash generating unit with the recoverable amount of the respective cash generating unit did not result in an impairment need for the annual reporting year 2023.

The recoverable amount of each cash generating unit is based on a discounted cash flow model that represents the fair value minus the cost of disposal. The projected cash flows used are obtained from the budgets, prepared by management, of the respective cash generating unit and approved by the Board of Directors. These budgets cover a three-year period. Cash flows beyond the three-year period are extrapolated using a cautious growth rate of 1%. The discount rate used equals the weighted cost of capital (WACC) calculated on the consolidated DEME Group figures, as per the third quarter of 2023, amounting to 7.83%.

'Concessions, patents and licenses' did not include indefinite useful lives intangible assets.

Within the line 'transfers from one heading to another', also transfers from assets under construction originally booked within property, plant and equipment were included.

In the 'addition of the year', an amount of 1.7 million euro was related to the capitalisation of development costs in the Concessions segment.

'Amortisation of the year' was recognised under 'depreciation and amortisation expenses' in the consolidated income statement for an amount of 3.9 million euro. Amortisation of development costs starts at the earliest on the date when financial close of the related project is reached.

In 'sales and disposals', a fully amortised licence fee, that expired was disposed of for an amount of 12 million euro.

The DP2 jack-up installation vessel 'Sea Installer'received an extensive upgrade, positioning the vessel for offshore wind farm projects in the US, whereas her sister vessel 'Sea Challenger' will similarly undergo the upgrade to support projects in Japan. For both vessels, the crane's lifting capacity increases from 900 tonnes to 1,600 tonnes. Additionally, enhancements such as a wider beam and longer legs enables both vessels to handle the next generation of mega wind turbines. The amount invested in the 'Sea Installer' is included in the additions in 'floating and other construction equipment'. The investment in the 'Sea Challenger' is carried out within a Japanese joint venture between DEME (49%) and partner Penta-Ocean Construction. This company will further upgrade and take ownership of the 'Sea Challenger' and reflag the vessel to the Japanese flag. As the joint venture is integrated according to equity method, the investment is not included in 'property, plant and equipment' of the consolidated statement of financial position. DEME is however financing the vessel through capital and shareholders loan, booked as financial asset.

In January 2022, DEME entered into an agreement with the Norwegian shipping company Eidesvik to acquire the DP3 offshore installation vessel 'Viking Neptun'. DEME upgraded the vessel into a cable laying vessel and from the first quarter of 2023 onward, the vessel has been actively engaged in project deployments. The reclassification of the vessel occurred from 'assets under construction' to 'floating and other construction equipment'.

In 2020 CDWE, the Taiwanese joint venture between DEME (49.99%) and partner CSBC, ordered the offshore wind installation vessel 'Green Jade' in Taiwan. This floating heavy-duty crane and installation vessel with DP3 capacity in Taiwan is equipped with an advanced crane featuring a lifting capacity of 4,000 tonnes. The vessel joined the fleet in July 2023 and since the third quarter of 2023 the vessel has been actively deployed in the thriving local offshore wind market. As the joint venture is integrated according to equity method, the new vessel is not included in 'property, plant and equipment'. However, DEME itself injected approximately 30 million euro in CDWE in 2020 and 13.3 million euro in 2021 as capital for the joint venture. There were no additional capital injections done by DEME in 2022 and 2023. The joint venture itself secured a long-term bank loan in the third quarter of 2023 to facilitate the further payment of the 'Green Jade'.

As part of its efforts to enhance its fallpipe vessel fleet, DEME made an investment in a new DP2 fallpipe vessel by purchasing and converting a bulk carrier. The vessel will be equipped with a central fallpipe system, incorporating a large inclined fallpipe. This design enables the vessel to conduct pre- and post-lay activities using rocks with larger diameters, close to subsea structures. This vessel named 'Yellowstone' will join the DEME fleet in the first half of 2024 and is still included within 'assets under construction'.

In the beginning of 2023, Transocean Ltd, a global leader in the offshore drilling industry, made a non-controlling investment for 15.7% in GSR (deep sea mining) through the contribution of a ultra-deepwater drilling vessel, and a cash investment. The 'Ocean Rig Olympia' is included within the additions and net book value of 'assets under construction' but the addition of the year is considered as a non-cash item.

In addition to the above contribution in kind of the 'Ocean Rig Olympia', the additions within 'assets under construction' mainly include the amounts invested in 2023 in the 'Yellowstone', in the 'Viking Neptun', in some additional modifications for the 'Orion', in a new offshore survey vessel and in a new office building. As of 31 December 2023, the 'Viking Neptun', 'Orion', and the new office building were transferred to 'floating and construction equipment' and 'land and buildings'.

In 2023, specific borrowing costs amounting to 1.6 million euros, related to assets under construction, were capitalised.

At 31 December 2023, the commitments made for investments in coming years amount to 37.5 million euro, mainly relating to upgrades of vessels 'Yellowstone', 'Viking Neptun' and for an offshore survey vessel.

The investments aimed at transitioning the DEME campus into a sustainable and energy-neutral head office have been incorporated into the net book value of 'land and buildings'.

A workshop in Zeebrugge, included within 'land and buildings' and with a net book value of 1.6 million euro, was transferred to 'assets held for sale' (note (15)).

'Depreciation charge and impairment cost of the year' increased to 355 million euro in total compared to 319 million euro in 2022. The higher level of depreciation charges in 2023 is attributed primarily to the investments in 'Orion', DEME's largest offshore installation vessel, that was added to the fleet mid 2022, and in 'Viking Neptun', the cable laying vessel that was integrated into the fleet in the first half of 2023. The amount also includes a 13 million euro impairment for 'Al Jarraf', one of DEME's cutter suction dredger vessels.

The investments in property, plant and equipment by joint ventures such as those in the 'Green Jade' and the 'Sea Challenger' are not reflected in 'property, plant and equipment' of the consolidated statement of financial position as already briefly said above. However, reference is provided to the segment reporting for 31 December 2023 and 31 December 2022 where the amounts included in the 'reconciliation' column under the lines 'net book value property, plant and equipment and right-of-use assets' and 'acquisition of property, plant and equipment and right-of-use assets' relate to joint ventures.

In 2022, 52% of DEME's capital expenditure was considered as taxonomy-eligible and aligned CapEx, while in the current period, this figure stands at 49%. This percentage is directly tied to DEME's fleet engaged in projects aimed at mitigating climate change, such as constructing and installing foundations and wind turbines, along with their shore connections. Additionally, as of now, climate risks are not significantly affecting the useful life of the Group's assets.

Sensitivity analysis

A sensitivity analysis has been performed by adjusting important assumptions used in the calculation of the recoverable amount.

Gross margin

The gross margin used in the discounted cash flow model is based upon the estimates of management and has been approved by the Board of Directors for a period of three years to come.

Sensitivity is tested by reducing the estimated gross margins to 95% of their initial value. Adjusting the gross margin downwards did not result in impairment for any of the mentioned cash generating units.

Discount rate

The discount rate used is the weighted average costs of capital, calculated on DEME Group figures. Future cash flows will negatively be impacted if the discount rate rises.

Sensitivity is tested by increasing the weighted average cost of capital with 1%. Adjusting the weighted average cost of capital to a higher value did not result in an impairment for any of the mentioned cash generating units.

Growth rate

The DEME Group assumes a careful growth of 1% of its gross margin in the years to come. Should the growth percentage be lower, the recoverable amount of each cash generating unit will drop.

Sensitivity is tested by reducing the growth rate to 0%. Adjusting the growth rate did not result in an impairment for any of the mentioned cash generating units.

Net book value at the end of the year		79,854	9,670	21,569	111,093

The net carrying amount of right-of-use assets amounts to 111.1 million euro at 31 December 2023, compared to 99.0 million euro at the end of 2022.

At 31 December 2023, the net book value of 'land and buildings' can be split into 63.7 million euro land and 16.1 million euro buildings. The significant increase in 'land and buildings' in 2023 is primarily attributed, among other factors, to the hire of additional land in Flushing.

The category 'floating and other construction equipment' encompasses various items, including support vessels and dry earth equipment.

The increase in additions in 'furniture and vehicles' is mainly related to the accelerated electrification of DEME's car fleet, an increase in fleet size (due to a higher number of cars) and the elevated lease cost associated with electric vehicles.

Lease liabilities corresponding to the right-of-use assets are detailed in note (22).

At 31 December 2022, the net book value of 'floating equipment' as part of 'floating and other construction equipment' contributes 99% to the total of this category.

Investments made in 2022 for 'Sea Installer' are included in the additions of 'floating and other construction equipment'.

In the first half of 2022, the DP3 offshore installation vessel 'Orion' joined the fleet and was transferred from 'assets under construction' to 'floating and other construction equipment'.

The amounts invested during 2022 in 'Orion', 'Viking Neptun' and 'Yellowstone' (all assets of the Offshore Energy segment), are included in the additions of 'assets under construction'.

In 2022, specific borrowing costs amounting to 1.5 million euros, related to assets under construction, were capitalised.

'Depreciation charge of the year' included a 0.4 million euro impairment cost.

In 2022, the vessel 'Groenewind', within the Offshore Energy segment and with a net book value of 32 million euro, was transferred to 'assets held for sale' (note (15)). The jack-up installation vessel 'Thor', with a net book value of 32.5 million euro and that was transferred in 2021 to 'assets held for sale', was sold in 2022 (note (2)).

In the line 'transfers from one heading to another', transfers to intangible assets were included as well. The transfer to 'other tangible assets' specifically related to the transfer of a vessel that was leased to an associate of the Group for a duration exceeding one year.

The line 'sales and disposals' within 'floating and other construction equipment' incorporated 52 million euro, covering both acquisition cost and cumulative depreciation of priorly activated and fully depreciated dry-docking costs.

In the second half of 2022, a mortgage on vessels for an amount of 18.3 million euro was released following the early repayment of the related long-term loan.

At 31 December 2022, the commitment made for investments in the coming years amounted to 192.6 million euro, mainly for the upgrades for vessels 'Viking Neptun', 'Sea Installer', 'Yellowstone' and additional modifications to the 'Orion'.

The majority of the 'share in the result of participations accounted for using the equity method' related to investments in associates is linked to the Concessions segment (37.4 million euro), more precisely its participations in Rentel NV, C-Power NV and Seamade NV that operate offshore wind farms, as well as to its participation in BAAK Blankenburg-Verbinding BV, Port of Duqm Company SAOC and Duqm Logistic Lands and Investment Company LLC. The result of the year of associates related to the Concessions segment in 2022 was 9.3 million euro. The increase in result in 2023 attributable to the offshore wind farms was partly driven by higher wind production, increased electricity prices, and the impact of new legislation in Belgium.

However, the positive contribution from the Concessions segment in 2023 was offset by the result of DEME's Taiwanese joint venture company in the Offshore segment, which absorbed project losses on the Zhong Neng project in Taiwan. The Offshore segment contributes for -35 million euro to the 'share in the result of participations accounted for using the equity method' related to investments in joint ventures.

As for 'dividends distributed by participations' in 2023, the amount received from associates comes from Rentel NV, Seamade NV and C-Power NV, whereas the dividend received from joint ventures mainly comes from Earth Moving Worldwide Cyprus Ltd (EMW).

Some joint ventures and associates finance substantial assets such as infrastructure works, offshore wind farms or vessels and therefore hold interest rate swaps (IRS). As per 31 December 2023, the 'other comprehensive income (OCI)' includes a positive amount of 14.0 million euro compared to a positive amount of 28.2 million euro at the end of 2022 (as such reflecting a year-over-year movement of -14.2 million euro). This figure reflects DEME's share in the fair value of the IRSs of Rentel NV, C-Power NV, Seamade NV, Normalux SA, BAAK Blankenburg-Verbinding BV, Port-La Nouvelle SEMOP and CDWE Green Jade Ltd, net of deferred tax assets. This fair value (DEME share) is indirectly reflected in the consolidated statement of financial position in the net assets of the investees for the same amount. The negative movement of the year in the hedging reserve of joint ventures and associates (-14.2 million euro) is related to the decline in market interest rates compared to the hedged interest rates. A minor amount of -0.024 million euro in the OCI movement is attributable to the remeasurement of net liabilities relating to defined benefit and contribution plans.

There are no equity accounted for investees where DEME has not recorded the share in the negative equity of the joint venture or associate. The equity accounted for investees for whom the share in the net assets is negative, are reallocated to other components of the investor's interest in the equity accounted investee such as shareholder loans on equity accounted investees. This reallocation is presented in the line 'other movements'. The amount can be positive or negative as the transfer from receivable to investment in joint ventures and associates is reversed once the net assets of the equity accounted investees are positive again. If after allocation the negative net asset exceeds the investor's interest, a corresponding liability (non-current financial liability) is recorded instead of a negative investment within non-current financial assets.

In 2023, the 'additions' include investments totalling 7.7 million euro in associates and 0.9 million euro in joint ventures The current year investments in associates mainly relate to the Concessions segment and more specifically to the investment in Hyport Coordination Company LLC, Ayre Offshore Wind Farm Ltd and Bowdun Offshore Wind Farm Ltd (also in 2022). In the beginning of last year (2022), the latter consortium (previously known as Thistle Wind) had been awarded 2 GW worth of option areas in Scotland's highly competitive ScotWind seabed leasing process. The investments in joint ventures for 2023 are related to an investment in D&S contractors NV, within the Dredging & Infra segment, whereas last year the investment in joint ventures related to the capital increase in Scaldis Salvage & Marine Contractors NV, within the Offshore Energy segment

Note 9 – Investments in joint ventures and associates

Earlier in this report, a comprehensive list can be found detailing the companies contributing to DEME's investments in joint ventures and associates. This list also includes the percentage of shareholding held by the DEME Group, the respective segment in which these companies operate, and their country of incorporation. None of these companies are publicly traded on any stock market. The joint ventures and associates have other contingent liabilities or commitments for which the Group has a corresponding commitment for an amount of 136.5 million euro (about 77.6 million related to Offshore Energy, 55.5 million to Dredging & Infra and 3.5 million euro for Environmental). In 2022 the amount of commitments amounted to 80.0 million euro (about 67.5 million related to Dredging & Infra).

In the financial statements, all investments in joint ventures and associates are accounted for using the equity method. Only in the segment reporting, a separate chapter in this report, joint ventures are accounted for using the proportionate consolidation method.

The changes over the period are explained below.

The amount of goodwill included in the carrying amount of the Group's interest in joint ventures is 0.3 million euro with no change in that amount in 2023 nor in 2022. There is no goodwill included in the carrying amount of associates.

In 2023, 'additions' totalling 19.6 million euro primarily consist of loans granted to Bowdun Offshore Wind Farm Ltd (6.7 million euro), Ayre Offshore Wind Farm Ltd (7.5 million euro), both for the ScotWind OWF-project, and Japan Offshore Marine Ltd (4.7 million euro).

'Disposals' within 2023 include an amount of 1.2 million euro for the repayment of the loan granted to Thistle Wind Partners Ltd in the preceding year, along with an additional amount of 1.1 million euro for the repayment of the loans granted to Bowdun Offshore Wind Farm Ltd and Ayre Offshore Wind Farm Ltd last year. The aforementioned loans have been substituted with new loans as detailed in the additions above. In 2022, a repayment of 11.5 million euro was included for loans granted to companies involved in the development and subsequent operation of the Rentel and Seamade offshore wind farms. Additionally, also a shareholder's loan of 3 million euro was paid back in 2022 within the Dredging & Infra segment.

No expected credit losses are recorded on other non-current financial assets as the repayment of the loans follows a solid business plan.

The equity accounted investees for whom the share in the net assets is negative, are allocated to other components of the investor's interest in the equity accounted investee such as shareholder loans on equity accounted investees. This allocation is presented in the line 'transfer (to) from other items'. The amount can be positive or negative as the transfer from receivable to investment in joint ventures and associates is reversed once the net assets of the equity accounted investees are positive again.

The non-current financial assets, other than loans to joint ventures and associates, mainly include long-term deposits and guarantees.

Tax impact of adjustments to current and deferred taxes relating to previous periods	2,248	7,353
Tax impact of losses for which no deferred tax assets were recognised (3)	25,557	2,854
Tax expense	49,618	31,361
Effective tax rate for the period	22.76%	23.95%
(1) The main components of the tax effect on non-taxable revenue are claw back of previously deferred depreciations and exempt capital gains on sale of assets as well as tax deductible losses on capital.

(2) The effective tax rate (2023: 22.76%) is lower than the nominal tax rate in Belgium (25%), because in several countries where the Group operated in 2023 the nominal tax rate is relatively lower and because of the application of the tonnage tax regime. The same applied for 2022 (effective tax rate of 23.95%). (3) The difference between 2023 and 2022 is caused by on the one hand the (re-)assessment of unrecognised deferred tax assets relating to tax losses during 2023 (increasing

the effective tax rate) and on the other hand the usage of unrecognised tax losses in 2023, decreasing the effective tax rate.

Deferred tax assets and liabilities split by origin

The changes of the period of deferred tax assets and liabilities split by their origin is set out below.

Deferred taxes (both assets and liabilities) related to fixed assets are presented separately. These deferred tax positions relate to both temporary differences between the statutory carrying amount and the carrying amount under the DEME Group depreciation policy and impairment corrections on fixed assets.

Deferred taxes regarding retirement benefit obligations (only deferred tax assets) are related to the provisions booked for retirement benefit obligations according to IAS 19 employee benefits.

The column reversal statutory provision is mainly related to the reversal of the statutory provisions for repair and maintenance which are not allowed under IFRSs.

Deferred taxes on other timing differences mainly relate to consolidation adjustments on running projects.

DEME operates in multiple jurisdictions with often complex legal and tax regulatory environments. The Group engages constructively with the tax authorities and where needed asks support from local advisors and counsels to obtain the most correct position on tax legislation and principles. However it is acknowledged that some of the positions are uncertain and include interpretation of complex tax laws as well as transfer pricing considerations. A deferred tax liability is recorded for each item that is not probable of being sustained on examination by the tax authorities and after using all legal remedies of defending the position before Court. The estimates are based on an approach which provides the best prediction of the resolution of the uncertainties with the tax authorities and is calculated using the most likely single amount or expected value method following IFRIC 23. The estimates are based on facts and circumstances existing at the end of the reporting period. Currently, the major uncertain tax positions (UTP) relate to ongoing potential tax litigations in Philippines, Belgium, the Netherlands and India.

Current taxes and deferred taxes recognised in comprehensive income	56,115	47,777

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the tax amount are those that are enacted or substantively enacted at the reporting date in the countries where the Group operates and generates taxable income.

Current income tax relating to items recognised directly in other comprehensive income is recognised in OCI and not in the statement of income.

Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred tax is provided using the liability method on temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

The operational activities of the Group are subject to various tax regimes with tax rates ranging from 0% to 48%.

Changes in fair value related to hedging instruments

Deferred tax assets are recognised for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognised to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilised. The impact of climate related matters was considered for this assessment. The deferred tax assets for tax losses and tax credits are booked separately. For a breakdown of the (un)recognised tax losses, see further section in this note.

Deferred tax assets and liabilities regarding financial derivatives only concern fully consolidated companies, see also the section regarding other comprehensive income.

Pillar Two

Pillar Two legislation has been enacted or substantively enacted in certain jurisdictions in which DEME operates (ao. Belgium). Ackermans en van Haaren NV (AvH NV) is the Ultimate Parent Entity ('UPE') for Pillar Two purposes of DEME Group's constituent entities. These constituent entities will therefore be in scope of the Pillar Two consequences applicable to the AvH Group.

The Pillar Two legislation will be effective for the AvH Group's financial year beginning 1 January 2024.

As a consequence of the fact that DEME Group is part of the AvH Group, the outcome of Pillar Two impact can only be assessed at the level of the AvH Group. It is impossible for DEME to reasonably estimate the impact of the (expected) Pillar Two legislation.

Based on an assessment made by the AVH Group, the AvH Group has identified potential exposure to Pillar Two top-up-taxes in certain jurisdictions. The exact exposure can currently not reasonably be estimated, a.o. since the outcome of the assessment will still be influenced by the outcome of the expected OECD Administrative Guidance to be published in the course of 2024. However, based on historical data, the AvH Group currently does not expect that such exposure may be significant in view of the consolidated financial statements.

As from financial year 2024 it is possible that, if the Pillar Two rules applied by the AvH Group lead to top-up-taxes in a certain jurisdiction, DEME will need to record part of the top-up-tax exposure in this jurisdiction in the financial statements of DEME Group.

DEME Group has applied the exception to recognising and disclosing information about deferred tax assets and liabilities related to Pillar Two income taxes.

Note 12 – Inventories

For the year ended 31 December

(in thousands of euro)	2023	2022
Raw materials	9,163	2,779
Consumables	22,852	22,917
Total inventories	32,015	25,696
Movement of the year recorded in statement of income (+ is credit)	6,319	13,528

Inventories can be split into Raw materials and Consumables. Raw materials are mainly related to ballast & dredged material and sand from the marine aggregate business within the segment "Dredging & Infra". Consumables mainly consist out of fuel, auxiliary materials, and spare parts.

The movement of the year of consumables is impacted by the moment of refueling of the vessels and the fuel usage up till closing date. Also the start-up of projects and preparation of the fleet can impact this movement.

No inventories are pledged as security for liabilities.

(*) "Business-related changes" relate to cumulative catch-up adjustments arising from a change in the measure of progress, a change in an estimate of the transaction price (including any changes in the assessment of whether an estimate of variable consideration is constrained) or a contract modification.

Given the high activity of the year, a positive impact on the net balance above is noted, reflected in a higher increase of contract assets compared to the increase in contract liabilities and advance payments. Contract liabilities further increased compared to 31 December 2022, amongst other also due to the loss to completion (included in contract liabilities) for some Offshore projects that has been accounted for in the 2023 figures. These losses to completion have been partially offset by the expected future turnover and specific variation orders, that are pending approval and completion, but that are assessed in line with IAS 37 provisions contingent liabilities and contingent assets and supported by solid legal opinions. The increase in advances received within Environmental mainly relates to the recent win in Feluy in Belgium where a brownfield will be remediated and transformed into an industrial estate in collaboration with public and private partners.

As a result of the high number of individual projects (with all different aspects regarding nature, type of clients, contract and payment conditions) a more in-depth description of changes in contract assets and contract liabilities compared to prior year is not deemed relevant.

Around 58% of the performance obligations, meaning the turnover to be executed in the upcoming years regarding the current ongoing construction contracts for which contract assets and contract liabilities are booked, is expected to be fulfilled by the Group next year, followed by 29% in 2025, 9% in 2026 and 4% beyond. The related contract assets and contract liabilities as of 31 December 2023 are expected to follow a similar timing for run-off.

Note 13 – Contract assets and contract liabilities

For the year ended 31 December

Contract assets and contract liabilities relate in compliance with IFRS 15 revenue from contracts with customers to the work in progress of construction projects executed by the Group and services rendered. Work in progress shows the balance of revenue recognised on those contracts less progress billings, advance payments and provisions for expected losses. Advances received are amounts received by the Group before the related work is performed. The Group presents those separately from other contract liabilities.

The Group carries out a diversity of projects, all with different aspects regarding e.g. nature and scope, type of clients, type of contract and payment conditions and geographical location. Most of the revenue is paid with an advance received at the beginning of the project followed by milestone payments after execution of the work and approval by the client.

(in thousands of euro / (-) is credit)	2023	2022
Contract assets	633,027	344,751
Contract liabilities	-447,363	-323,300
Advances received	-84,486	-72,539
Net balance	101,178	-51,088

Contract assets are the Group's right to consideration in exchange for goods or services that the entity has transferred to a customer when that right is conditioned on something other than the passage of time. A contract asset arises when the Group performed works for a customer that are recognised as revenue to date but are not yet invoiced or paid. As such the revenue recognition reflects the rate at which the Group's performance obligations are fulfilled corresponding to the transfer of control of a good or service to the customers. When there is no transfer of control throughout the contract,revenue is still recognised over time, based on the fact that the asset created has no alternative use, as well as the fact that the Group has an enforceable right to the payment for performance completed to date. Contract assets turn into receivables when those works are accepted by the client.

Contract liabilities are the Group's obligation to transfer goods or services to a customer for which the entity has received consideration from the customer. A contract liability arises when the Group has invoiced the customer or received payment from them while the work was not done yet and the invoices and/or payments exceed the revenue recognised to date. Provisions are recognised for expected losses on work in progress as soon as they are foreseen and if necessary, any profit already recognised is reversed. Those provisions are also recognised as contract liabilities for an amount of 54.2 million euro as of 31 December 2023, compared to 24.8 million euro at the end of 2022.

The determination of estimated profit (or loss) is based on estimated costs and revenues of the related projects and for profitable projects only, in proportion to the stage of completion. These estimates and judgements may contain some uncertainties.

Other operating receivables	12,842	8,836
Total trade and other operating receivables	514,043	469,529

At 31 December 2023, trade and other operating receivables amounts to 514.0 million euro, compared to 469.5 million euro at year-end 2022. The increase of the year is mainly related to an increase in activity but also due to the progress of major projects and the timing of invoicing as contract assets are transferred to receivables upon acceptance by the client. The increase in outstanding trade receivables is by all means not caused by an increase in overdue amounts.

The ageing balance of outstanding trade receivables is more elaborated in note (20). The Group carries out a diversity of projects, all with different aspects regarding e.g. nature and scope, type of clients, type of contract, payment conditions and geographical location. A large part of the consolidated turnover is realised through public or semi-public sector customers and is spread out over a large number of clients. The level of counterparty risk is also limited by examining clients solvency prior to finalising contracts and by putting the required payment guarantees in place (including credit insurance policies with public service credit insurers such as Credendo and private credit insurers, bank guarantees and through letters of credit).

For current income tax receivables reference is made to note (11).

Other operating receivables mainly relate to amounts due from joint ventures, current accounts with consortium partners and personnel advances. Other operating receivables also includes the short-term part of1.2 million euro of the long-term loan of 10 million euro that was granted to the buyer of the 'Thor' vessel in 2022. Reference is made to note (10) other non-current assets.

Note (27) related party disclosures summarises amongst others all receivables and payables towards joint ventures and associates.

Balance at 31 December		1,630	31,997

According to IFRS 5 non-current assets held for sale and discontinued operations the following conditions must be met for an asset (or 'disposal group') to be classified as held for sale:

• management is committed to a plan to sell
• the asset is available for immediate sale
• an active programme to locate a buyer is initiated
• the sale is highly probable, within 12 months of classification as held for sale
• the asset is being actively marketed for sale at a sales price reasonable in relation to its fair value
• actions required to complete the plan indicate that it is unlikely that the plan will be significantly changed or withdrawn

Per 30 June 2023, DEME management was of the opinion that all of the conditions had been fulfilled and a sale for the workshop in Zeebrugge would be highly probable within the next 12 months. The net book value of the workshop amounted to 1.6 million euro and was as such presented as an asset held for sale. All of the above conditions remained the same as per 31 December 2023.

Last year at 31 December 2022, DEME management decided that all of the conditions were fulfilled and that a sale within the next 12 months was highly probable for the vessel 'Groenewind' within the Offshore Energy segment. The net book value of the vessel at that time was 32.0 million euro, which was the lower of the carrying amount and fair value at closing date. The vessel was sold in July 2023 resulting in a gain on disposal that is included in 'other operating income' (note (2)).

Dividends

All of the Shares will entitle a holder thereof to an equal right to participate in dividends. All of the Shares participate equally in the Company's profits (if any). Subject to the Company's earnings, financial condition, capital requirements and other factors considered important by the Board of Directors, the availability of distributable reserves and the approval by the Shareholders' meeting, the Company intends to declare and distribute an annual non-cumulative dividend to its shareholders based on a target pay-out ratio of 33% of the Group's net profit. There can be no assurance as to whether dividends or similar payments will be paid out in the future nor, if they are paid, as to their amount.

For 2023, the Board of Directors will propose to the General Assembly, on 15 May 2024, to distribute a gross dividend of 2.1 euro (1.47 euro net) per share, an increase of 40% compared to last year. Subject to the approval of the General assembly, the record date is proposed to be set at 22 May 2024 and payment date on 27 May 2024.

For 2022, the General Assembly of 17 May 2023 approved the distribution of a gross dividend of 1.5 euro (1.05 euro net) per share. This dividend was paid on 10 July 2023 for a total amount of 37,971,723 euro.

The Company recognises a liability to pay a dividend once the distribution is authorized. A corresponding amount is recognised directly in equity.

The line 'other' relates to the fact that since 29 June 2022, there is a new parent company DEME Group NV on top of DEME NV, that was the parent company of the Group at the beginning of 2022. The retained earnings and other reserves at the end of 2022 are those of the new parent company DEME Group NV.

Other current assets	70,408	124,233

Deferred charges and accrued income include amongst others deferred hedge charges for construction contracts, only for their percentage not completed. The hedge charges of construction contracts are recorded as construction cost for the percentage completed. The decrease in 2023 compared to 2022 is mainly related to the decrease in deferred hedge charges for the offshore energy contracts in the US.

The decrease in advance payments on purchases and cost of material regarding constructions contracts for costs not incurred is mainly related to the offshore energy contracts in the US that are now up and running.

In contrast to DEME's previous asset financing approach prior to 2015, which involved seeking individual banks (or a few banks) for each investment and offering tangible securities to secure the loans (such as vessel mortgages), the long-term loan facilities and asset-based loans listed above do not require any securities other than the guarantee provided by the Group's parent company. This strategy provides maximum flexibility concerning the underlying assets, enabling intragroup sales and reflagging as per project requirements.

Cash and cash equivalents

Cash and cash equivalents relate to cash and cash equivalents centralised at DEME's internal bank, DEME Coordination Center NV, but also at operational subsidiaries and joint operations. Therefore, a portion of the consolidated cash and cash equivalents is not always immediately available as a result of transferrestrictions, joint control (in joint operations) or other legal restrictions. At 31 December 2023, the amount of cash available at DEME's internal bank ready for use by the Group amounts to 101 million euro out of 389 million euro cash and cash equivalents. As such an amount of 288 million euro is not immediately available for use. At the end of 2022 the cash that was immediately available at DEME's internal bank amounted to 314 million euro out of 522 million euro cash and cash equivalents, resulting in 208 million euro cash not immediately available for use.

To finance the DEME Group capital expenditure (vessels and other equipment), equity participations (e.g. by DEME Concessions) and acquisitions, DEME sources its funding mainly through term loan facilities, which are available for general corporate purposes as well as through asset-based loans.

Currently, DEME Coordination Center NV, which serves as in-house bank financing the DEME-entities, has term loan facilities with eleven different commercial banks. Same as for the revolving credit facilities, the documentation is signed bilaterally (no club deal), catering for optimal financing conditions and maximum flexibility. The term loan facility documentation is identical for all banks, apart from the amount, tenor and commercial conditions.

The net financial debt of -512 million euro as of 31 December 2023 was essentially unchanged from year-end 2022. However, compared to 30 June 2023, net financial debt was 203 million euro lower mainly due to a strong cash flow generation in the second half of the year. Net debt over EBITDA at the end of 2023 was 0.86 compared to 1.09 a year ago.

In 2023, no new long-term loan facilities were added, only two asset-based loans. For reference, in 2022, additional term loan facilities totalling 440 million euro were received with amortisation scheduled over eight years.

The total subordinated loan is contracted by entity Combined Marine Terminal Operations Worldwide NV (CTOW) and includes the part due to the partners in the company. As per contract modalities no fix instalments are due, therefore the loan is reported as long-term debt and will only be reported as short-term debt in the year before the maturity date.

To realise DEME's ambitious sustainability goals in all aspects of its activities, the Group converted its long-term financing into sustainabilitylinked loans in the course of 2022. This commitment underlines DEME's vision of achieving a sustainable future and at the end of 2023 the sustainability linked loans amount to 649.7 million euro. The commercial terms of those loans are directly linked to DEME's sustainability performance in two areas: (1) safety at work (calculation of worldwide LTIFR) and (2) use of low-carbon fuel, which are in line with two material topics of its current ESG materiality matrix. Meeting or not meeting the targets that are set for the key performance indicators (KPIs) have an impact on the interest margins applied to the sustainability-linked loans. In 2023, DEME achieved the goal for both KPI's.

(*) Early repayment in 2023. Initial maturity till 2027 for both loans.

The interest rate of the long-term loan facilities is based on EURIBOR plus a margin which is updated each semester based on DEME's leverage ratio. The interest rate risk resulting from this floating interest rate base, is hedged through interest rate swaps (note (21)). The interest rate of the asset-based loans is fixed. Next to the long-term loan facilities and asset-based loans, DEME has lease liabilities and other long-term loans.

At closing date, the instruments qualified as cash flow hedges have the following characteristics:

2023 (in thousands of euro)	Non-current asset	Non-current liability	Current asset	Current liability	Total net balance fair value
Interest rate swaps	19,862	-	10,938	-	30,800

	150,913	135,742	280,536	82,500	649,691

Some joint ventures and associates finance significant assets such as infrastructure works, offshore windfarms or vessels and therefore also hold interest rate swaps (IRS). Per 31 December 2023, the other comprehensive income (OCI) of the current period includes an amount of +14.0 million euro compared to +28.2 million euro at the end of 2022 for DEME's share in the fair value of the IRSs of Rentel NV, C-Power NV, Seamade NV, Normalux SA, BAAK Blankenburg-Verbinding BV, SEMOP Port-La Nouvelle and CDWE Green Jade Ltd, net of deferred tax assets. The amount for 2023 is lower compared to 2022 due to the decrease of long-term interest rates.

At DEME the hedging instruments swap the variable interest rate into a fixed one as described in the tables below. Lease liabilities are not included in the tables below. Reference is also made to note (20) interest-bearing debt and net financial debt.

As in 2022, the entire Group's outstanding long-term interest-bearing debt portfolio features a fixed interest rate character, mitigating the Group's exposure to interest rate fluctuations. The Group does not have interest rate hedges for its floating rate short term borrowings, done via placement of commercial paper and utilisation of its revolving credit facilities. Consequently, the amount and interest rate for short-term credit facilities, both before and after accounting for derivatives, remain unchanged, as illustrated in the table above.

Credit facilities and bank term loans

Revolving credit facilities are contracted by DEME Coordination Center NV with four different commercial banks, all being relationship banks for DEME At 31 December 2023, the Group has 110 million euro available but undrawn bank credit facilities (2022: 125 million euro). In addition, at year-end 2023 the Group had an outstanding issued amount of commercial paper for 30 million euro (2022: none). DEME has the possibility to issue commercial paper for amounts up to 250 million euro in total, compared to a lower amount of 125 million euro last year. The commercial paper programme is accommodated by three agents (banks) that place DEME debt with external investors in tranches of different sizes and for tenors ranging from a few weeks up to maximum one year.

Financial covenants

Bilateral loans are subject to specific covenants. The same set of financial covenants as for the revolving credit facilities is applicable for the long-term loan facilities. At both 31 December 2023 and 2022 the Group complies with the solvency ratio (>25%), the debt/EBITDA ratio (<3), and the interest cover ratio (>3), that were agreed upon within the contractual terms of the loans received.

The solvency ratio that should be higher than 25% is computed as shareholders' equity less intangible assets and goodwill divided by the balance sheet total. The solvency ratio at 31 December 2023 equals 39.4 % (2022: 38.1%).

The debt/EBITDA ratio computed as total net financial debt (without subordinated and other loans) divided by EBITDA, should be lower than 3. The debt/EBITDA ratio at 31 December 2023 amounts to 0.86 (2022: 1.09).

The interest cover ratio computed as EBITDA divided by net financial interest charges (interest charges less interest income), should be higher than 3. The interest cover ratio at 31 December 2023 is 50.2 (2022: 53.3).

Note 21 – Financial risk management and financial derivatives

For the year ended 31 December

The Group's financial instruments are cash and cash equivalents, trade and other receivables, interest-bearing debt, trade and other payables and derivatives. Derivatives are designated exclusively as hedging instruments and not for trading or other speculative purposes. The Group is exposed to the following risks linked to financial instruments: Market risk, Credit and Counterparty risk and Liquidity risk.

Market risk

To finance its investments and activities, DEME frequently makes use of external finance, both on short and long-term. The extent of leverage may expose the Group to various risks, including increasing its vulnerability to downturns or adverse changes in general economic, industry or competitive conditions and government regulations and requiring a substantial portion of its cash flows from operations to be dedicated to the payment of principal and interest on the Group's indebtedness, therefore reducing its ability to use its cash flows to fund its operations, capital expenditures and future business opportunities.

Market risk is defined to be the risk that captures changes in market price variations (foreign exchange rates, interest rates, fuel prices,…) that could affect the Group's income statement or the value of its assets and liabilities. The objective of market risk management is to manage and control market risk exposures and to keep the market risk position within acceptable boundaries while achieving the best possible return.

Market risk consists out of:

• interest rate risk
• currency risk
• price risk/commodity risk

Interest rate risk

DEME contracts considerable financing for the acquisition of its fleet and related capital expenditure. Interest rate risk can be defined as the extent to which the results or value of a financial transaction are affected by a change in market interest rates.

The interest rate risk management is centrally performed within the Group.

To achieve the best possible balance between financing costs and the volatility of the financial results for its long-term borrowings, DEME covers the vast majority of the risks of changes in the underlying floating interest rates through derivative financial instruments, mainly by using interest rate swaps. As for the uncovered part of the interest rate risks (which mainly relate to short-term borrowing if applicable) adverse changes in variable interest rates may lead to increases in the interest charges borne by DEME.

These hedging instruments generally equal the same notional amounts and generally have the same maturity dates as the hedged debts. As such the swaps are determined as an effective hedge of outstanding or anticipated borrowings and meet the hedge accounting requirements of IFRS 9. The fair values of the effective portion of the hedging instrument are therefore recognised directly in the other comprehensive income under hedge accounting treatment. The ineffective part of any gain or loss on the financial instrument will be taken in result.

A one-off basis swap was added in 2023 to several ongoing IRSs on Deme Coordination NV loans to optimise and follow a market opportunity at the time. The underlying loans as such were renegotiated from a 6-monthly interest payment to a 3-monthly one.

The main foreign currency companies contributing to the Group's turnover have USD, GBP, DKK, SGD, INR, MXN, and PLN as their currency. For 2023 these entities, especially in USD & GBP, even contributed 42% to the Group's turnover. For 2022 this was only 21%. The Group does not hedge against translational currency risk.

Transactional currency risk

The global nature of DEME's activities means that payments made further to contracts may be in a variety of currencies, thus exposing DEME to exchange rate risks. Similarly, purchases and expenditure in foreign currencies also give rise to exchange rate risks. Most of the Group's purchases are typically transacted in euro or USD. This means that the Group will face a risk of exchange rate fluctuation when the sales are made in a different currency than the purchase. DEME may be unable to pass along increased costs to its customers.

• The financing transactional currency risk can be considered to be nil for the outstanding long-term debt (without considering

• Financing & Investing: DEME's transactional currency risk regarding financing and investing activities could arise from financial loans denominated in currencies other than the euro.
  • lease debts which are mainly in euro).
  • except for ScotWind OWF-project (in GBP), minimising the exposure on transactional currency risk.
  • the translational currency risk as described above.

• Long-term loans given to joint ventures & associates (recorded as other non-current financial assets note (10) are in euro, • Capital funding in euro in joint ventures and associates denominated in other currencies (e.g. CDWE Taiwan Ltd) is subject to

Total effective average interest rate after hedge increased from 1.58% at year-end 2022 to 1.91% at 31 December 2023, although outstanding debt (excl. lease debt) decreased compared to last year. Older IRSs are winding down, which may now reflect the weight of the latest 'more expensive' loans. New asset-based loans and the withdrawal of 440 million euro new term loan facilities in June 2022 were granted at higher interest rates compared to earlier ones.

Sensitivity to the interest rate risk

The Group could be subject to the risk of fluctuating interest rates for cash flows relating to financial instruments at floating rate that are not hedged. Though because of the fact that the entire Group's outstanding debt portfolio (short and long-term) after hedging, has a fixed interest rate character both at year-end 2023 as well as at 2022, the exposure of the Group to interest rate fluctuations is eliminated. As such an increase or decrease of EURIBOR with 50 base points at closing date (assumed that underlying figures remain constant over the year), will not have any impact on the current interest charges in the income statement.

The Group does not maintain a hedging ratio as an instruction as such, although the hedge ratio is kept as high as possible. As shown above, for the interest rate risk the ratio between fixed and floating interest rates even amounts to 100%. The funding activity with respect to the fully owned subsidiaries is fully centralised at Deme Coordination Center NV that has taken out long-term loans from various banks at floating rates, that are hedged accordingly. The amount of commercial paper issued at year-end 2023 is defined as short-term credit facility also at fixed rate.

The cash flow schemes that are hedged by means of IRSs are one on one identical to the cashflow schemes representing each individual loan contract. When in-effectiveness occurs, the hedge is being amended accordingly. When loans are taken out on an associate orjoint venture level, DEME depends on the partner for hedging decisions.

Currency risk

DEME is exposed to risks associated with fluctuations in currency exchange rates. The Group's currency risk can be split into two categories: translational and transactional currency risk.

Translational currency risk

DEME's reporting currency is euro, however, given the Group's global operations, a significant portion of the Group's assets, liabilities, expenses and revenue are denominated in currencies other than euro. Such assets, liabilities, expenses and revenue are translated to euro at the applicable exchange rates to prepare the Group's consolidated financial statements. Therefore, fluctuations in exchange rates between euro and such other currencies affect the value of those items expressed in euro terms in the Group's consolidated financial statements. A change of one or more of the foreign currencies in which DEME's local subsidiaries operate against euro impacts its revenue and profitability expressed in euro terms accordingly. Changes in the euro values of the Group's consolidated assets and liabilities resulting from exchange rate movements may cause the Group to record foreign currency gains and losses through profit or loss, or through its cumulative translation adjustment reserve recognised in other comprehensive income and accumulated in equity. In 2023 the change in cumulative translation adjustment reserve amounts to -6.8 million euro compared to 3.1 million euro last year.

Sensitivity

Sensitivity to currency fluctuations is mainly related to the evolution of a portfolio of foreign currencies versus the euro.

The fair value of foreign currency monetary items is impacted by currency fluctuations. In order to eliminate most of these effects in foreign currencies, the Group uses monetary items and/or derivative financial instruments as described above, which are meant to offset the impact of such results to a major extent.

The following analysis is performed supposing that the amount of financial assets/liabilities and derivatives as at 31 December 2023 and 2022 would remain constant over the year. A variation of 5% (appreciation of the EUR) at closing date would give an increase or a decrease in the balance sheet items as follows (mainly EGP, GBP, USD, PLN):

• Operational activities: Given the international character of its business operations and the execution of contracts in foreign currency, DEME is exposed to currency risks. DEME's transactional foreign currency risk arises from commercial flows denominated in currencies other euro.
  • In 2023, 65% of the Group's turnover was contracted in EUR followed by USD, GBP, DKK, INR, SGD, MXN and PGK. In 2022 this was 79% in EUR, followed by USD, SGD, INR, GBP, DKK, BRL and UYU.
  • The Group's expenses are mainly in euro. To a lesser extent costs are charged in a currency not equal to the euro or in the currency of a country in which our activities are performed.
  • The residual foreign currency risk is assessed on a case-by-case basis and, if necessary, DEME uses forward exchange contracts to hedge its residual foreign currency risk on projected net commercial flows denominated in currencies other than the euro. The fair value variation of exchange rate instruments is considered as construction costs. This variation is presented as an operating result.
• Exchange rate risk for large projects and large investments are hedged as much as possible, also for smaller volumes hedging is taken out in most cases. When in-effectiveness occurs due to timing mismatches, the FX-trades are being rolled to the future. Ineffectiveness in terms of volumes is in most cases an underhedge. When overhedge occurs due to underlying flow being cancelled or being paid in other currency than the hedged currency, the hedge will be amended accordingly.

Credit risk on accounts receivable/ Counterpart risk:

The aging of trade receivables (gross amount and excluding other operating receivables) (note (14)) is as follows:

2023			Expired	Expired	Expired	Expired	Expired	Expired
(in thousands of euro)	Total	Not expired	<1 month	<2 months	<3 months	<6 months	<1 year	> 1 year
Trade receivables	458,784	285,063	56,656	37,392	3,869	33,468	13,567	28,769
2022 (in thousands of euro)	Total	Not expired	Expired <1 month	Expired <2 months	Expired <3 months	Expired <6 months	Expired <1 year	Expired > 1 year
Trade receivables	424,476	272,694	30,037	46,527	26,075	8,509	14,610	26,024

Overdue receivables in the different buckets above, generally relate to pending settlements, additional works & subsequent contract modifications accepted by the customers but to be recovered by an overall agreement with the client and that are all part of a broader negotiation process. Revenues and earnings are only recognised in the accounts when it's probable that they will be realised.

As a result of all the reasons mentioned above, and especially because outstanding receivables are generally covered by Credendo or other instruments, the amounts written off are limited to 10.9 million euro in 2023 (13.0 million euro in 2022).

The credit history of the Group indicates that credit losses are insignificant compared to the level of activity. Therefore, management is of the opinion that credit risk is adequately controlled by the current applicable procedures. The payment behaviour of the Group's customers remained also unchanged in 2023. At the reporting date there was no concentration of credit risk with any customers.

A detailed movement in amounts written off trade receivables is presented below:

(in thousands of euro)	2023	2022
Balance at 1 January	-13,018	-18,423
Additional provisions	-36	-232
Amounts used	2,013	6
Amounts unused	177	5,631
Translation (losses) / gains	-	-
Balance at 31 December	-10,864	-13,018

The outstanding balance of amounts written off in 2023 and 2022 mainly relates to the allowance for the insolvency of a client in 2019, for which DEME Offshore carried out maintenance works on offshore wind farms. The movement in amounts written off of the year is partially caused by the final write-off of a receivable for an old project in Egypt and the related bad debt allowance. The allowance recognised as a cost in prior years was reversed within amounts written off, whereas the write-off of the receivable is booked as a service cost in the consolidated statement of income. Reference is also made to note (2) other operating expenses.

All other financial assets of the consolidated balance sheet are considered as not expired.

Credit risk on cash and cash equivalents

DEME is also exposed to counterparty risks when investing its available assets and when subscribing to financial derivatives. DEME has a policy to minimise counterparty risk by avoiding concentrations of these and in such matters working only with banks with which it has a longstanding relationship, but it is not possible to entirely exclude credit risks of financial counter parties.

The Group has cash and cash equivalents of 389.1 million euro at 31 December 2023 (2022: 522.3 million euro). The cash and cash equivalents are held with reputable bank and financial institution counterparties that have good investment grade credit ratings.

Price risk/ commodity risk

DEME is also exposed to commodity risks and hedges against oil price fluctuations by entering into swap contracts. The fair value variation of these instruments is considered as construction costs. This variation is presented as an operating result. The fair value and notional amount of these instruments can be found below (+ is asset / -is liability):

Credit and counterparty risk

A credit risk may arise in the event a customer or counterparty fails to perform its contractual obligations in respect of DEME in accordance with the provisions of the contract concerned.

Non-payment by a customer may be the consequence of a lack of liquidity, bankruptcy or fraud on the part of the customer or be attributable to the general political or economic situation in the customer's country. Although DEME aims to minimize the credit risks of its customers by examining their solvency prior to finalising the contract and putting the required payment guarantees in place (including credit insurance policies with public service credit insurers such as Credendo and private credit insurers, bank guarantees and through letters of credit) it is not possible to entirely exclude the credit risks of customers.

A large part of the consolidated turnover is also realised through public or semi-public sector customers (as such less risk for insolvency). Moreover the level of counterparty risk is also limited by the large number of customers within its project-oriented business. No clients are classified as material clients within the turnover of the Group for 2023.

Though to contain the risk, DEME constantly monitors its outstanding trade receivables and adjusts its position if necessary.

Liquidity risk & capital management

Although DEME operates strict financial policies, puts required payment guarantees in place (including credit insurance policies with public service credit insurers such as Credendo and private credit insurers, bank guarantees and letters of credit) and ensures that there is a diversity of sources of finance and repayment periods, it cannot entirely be ruled out that the non-performance of significant payment obligations by customers or the inability to arrange adequate external financing subject to acceptable conditions could have a negative effect on the cash flow and liquidity of DEME and thus have a negative impact on the activities, financial situation and results of DEME. All these factors might result in DEME having difficulties to comply with its credit facility covenants. If DEME's future cash flows from operations and other capital resources would be insufficient to comply with its payment obligations or to fund its liquidity needs, DEME may be forced to adapt its business activities and capital expenditures, sell assets, obtain additional debt or equity capital, restructure or refinance all or a part of its debt on or before maturity or forgo opportunities such as acquisitions.

The liquidity risk is limited by spreading borrowing among several banks, agreeing a variety of repayment periods and also by mitigating the credit risk as described above. The maturity analysis below provides an overview of the gross amounts to be repaid by the Group (contractual repayment of initial amount including interests) for the outstanding loans received from credit institutions.

2023 (in thousands of euro)	More than 5 years	Between 1 and 5 years	Less than one year	Total
Credit institutions: amount outstanding according to the consolidated statement of financial position	83,136	481,498	191,093	755,727
Credit institutions: gross amount (cash out to be paid)	84,915	505,779	204,114	794,808

DEME aims to maintain a healthy balance between the consolidated Group equity and the consolidated net debt. DEME has significant credit facilities and guarantee facilities with various international banks. In addition, it has a commercial paper programme to cover its short-term borrowing requirements if needed. The risk on its current long-term variable interest bank loans has been entirely covered by making use of interest rate swaps (see interest rate risk factor).

DEME mainly invests in equipment with a long lifespan, which is written off over several years.

For that reason, DEME seeks to structure a substantial part of its debts as long-term debt. Since 2015, DEME has worked out a new bank financing structure, based on bilateral unsecured long-term financing with several banks. DEME must in the context of some of its long-term credit facilities respect certain covenants. Any breach of these covenants could give rise to the acceleration of the loans.

At 31 December 2023 as well as at 31 December 2022, the Group complies with the solvency ratio (>25%), the debt/EBITDA ratio (<3), and the interest cover ratio (>3), that were agreed upon within the contractual terms of the loans received. (note (20))

At year-end 2023, DEME has a net financial debt of -512.2 million euro (note (20)) and a Group equity of 1,960.8 million euro. The Group equity of the DEME Group includes share capital, share premium, consolidated reserves and non-controlling interests. The entire equity is used to finance the operations described in the corporate purposes of the subsidiaries.

At 31 December 2023, the Group has 110 million euro available but undrawn bank credit facilities, compared to 125 million last year.

The explanatory note (20) interest bearing debt and net financial debt discloses the changes in liabilities arising from financing activities and the extent to which cash and cash equivalents are not freely available as a result of transfer restrictions, joint control or other legal restrictions. Note (26) working capital also elaborates on how DEME manages cash and liquidity.

Fair values & hierarchy

The fair values are classified in three levels according to the valuation hierarchy of IFRS 13, depending on the type of input used for the valuation of financial instruments.

• Level 1 instruments are unadjusted quoted prices in active markets for identical assets and liabilities. No valuation model is used. In level 1, we find all financial assets (valued at fair value) with a public listing in an active market
• Level 2 instruments are prices quoted for similar assets and liabilities in active markets, or data based on or supported by observable market data. A valuation based on observable parameters such as discounted cash flow model, the comparison with another similar instrument, the determination of prices by third parties
• Level 3 instruments are non-observable data for determining the fair value of an asset or liability, e.g. some financial assets for which no public listing is available, loans and advances to customers, valued at amortised cost etc

Set out below is an overview of the carrying amounts of the Group's financial instruments that are shown in the financial statements. All fair values mentioned in the table below relate to Level 2. During the reporting periods, there were no transfers between Level 1 and Level 2 fair value measurements, and no transfers into and out of Level 3 fair value measurements.

Note 23 – Retirement benefit obligations

The DEME Group contributes to pension and early retirement plans in several of the countries in which it operates. These benefits are recognised in accordance with IAS 19 employee benefits. About 77% of the retirement benefit obligations is related to Belgian employees. The DEME Group currently foresees several occupational pension plans in favor of these employees:

• The pension schemes of the type defined benefit are funded either through a group insurance branch 21 either through a company pension fund. Assets of the pension fund "KBC Pension Fund Service deelvermogen Decloedt" have been estimated starting from the market value as at 31 October 2023, reported by the investment manager, taking into account the planned cash flows for the rest of the year and assuming a 0% financial return for the months of November and December 2023. Assets of the insured plans are calculated per person as the present value at the discount rate of the accrued benefits according to IAS 19 paragraph 115, with the application of a correction on the discount rate on the part of the present value that exceeds the mathematical reserves, to take employer funded through a group insurance branch 21. In accordance with Belgian social legislation, the employer has to guarantee an interest rate on the employer contributions paid in defined contributions plans of 3.25% for contributions paid until 1 October 2016. For contributions paid as from 2016 the Belgian legislation decided to use a yearly variable interest rate based on a Belgian termination date of the labor contract). All contributions paid before a change in return rate will be held at the original interest rate companies towards the employers regarding the effectuation of the group insurance contracts. The employer liabilities as at 31 assuming that the interest rate with respect to the legal minimum guarantee increased from 1.75% to 2.50% for the future. Assets are calculated per person as the present value at the discount rate of the accrued benefits according to IAS 19 paragraph 115, with the application of a correction on the discount rate on the part of the present value that exceeds the mathematical reserves, to take

• The DEME Group also sponsors pension schemes of the type defined contributions for Belgian employees, which are entirely state bond of 10 year, with an absolute minimum return of 1.75% and an absolute maximum return of 3.75% (0% as from the in the future (legal horizontal guarantee). This horizontal guarantee is not fully covered by the rates provided by the insurance December 2023, resulting from this legal guarantee, were valued with respect to the contributions attributed in the past and into account the default risk of the insurance company. Total assets are then increased with the value of the financing funds

DEME's subsidiaries in the Netherlands operate a number of defined benefit pension schemes. Without exception, these plans are insured with an authorized insurance company in the Netherlands and are closed for new entries and accruals. The schemes net liabilities arise from the obligation for the entities to index accrued pension benefits and benefits in payment and/or the obligation to pay guarantee costs to the insurance company.

The net liability related to the retirement benefit obligations in Belgium and The Netherlands decreased from 56.9 million euro to 51.9 million euro mainly due to higher contributions made by the Group to the defined benefit and defined contribution plans and change in demographic assumptions due to update of the turnover rates.

The following methods and assumptions were used to estimate the fair values in the tables above:

• Cash and cash equivalents, trade and other operating receivables (excluding VAT and corporation taxes (note (14)), trade payables and other amounts payable (note (24)) approximate their carrying amounts because they have a short-term maturity
• The fair value of interest-bearing debt is estimated by discounting future cash flows using the effective interest rates currently available for debt on similar terms, credit risk and remaining maturities; where the interest rate is variable (floating), the fair value is considered to be similar to the carrying amount. A similar approach is used for non-current (financial) assets
• The Group enters into derivative financial instruments with various counterparties, principally financial institutions with investment grade credit ratings. Derivatives valued using valuation techniques with market observable inputs are mainly interest rate swaps, fuel hedges and foreign exchange forward contracts. The models incorporate various inputs including foreign exchange spot and forward rates and interest rate curves

Contingent assets and liabilities

Based on available information at the date on which the financial statements are approved by the Board of Directors, DEME is not aware of any other contingent assets or liabilities than the ones described below:

• Since 2018, the Group has been involved in discussions with Rijkswaterstaat in the Netherlands related to the execution by one of its subsidiaries of the Juliana Canal widening project. Following intense discussions, a settlement (included in the first half of 2023) has been reached with Rijkswaterstaat in the Netherlands whereby Rijkswaterstaat paid De Vries & Van De Wiel Kust-en Oeverwerken BV and Rijkswaterstaat fully and finally released De Vries & Van De Wiel Kust- en Oeverwerken BV from all and any liabilities in relation to the project. As such this matter can be closed.
• One of the Group Companies is involved in legal proceedings initiated by the Dutch Waterboard (het Waterschap Vallei Energy Veluwe) against a consortium of which said Group Company is a member, due to allegedly unauthorized activities on the project Eemdijk. The alleged unauthorised activities were fully and solely executed by the Group Company's former partner in the consortium, as the Group Company withdrew from the project even before the start of the actual execution of any works. The Group Company was however not able to formally withdraw from the consortium as well. Meanwhile, said former partner has filed for bankruptcy. The outcome of this claim is still uncertain. However, based on the current circumstances and subject to the insurance policy conditions, the outcome of the aforementioned pending legal proceedings is not expected to have a material impact on the Company's future results and cash flows.
• In September 2023, certain companies of the DEME Group were summoned to appear before the criminal court in Ghent. This decision follows a judicial investigation carried out in respect of the circumstances in which a contract was awarded in April 2014 by negotiated procedure to Mordraga, a former Russian joint venture company of the DEME Group, for the execution of dredging works in the port of Sabetta (Russia). The works were carried out in the summer months of 2014 and 2015. The investigation was launched following a complaint lodged by a competitor, to whom said contract was not granted by negotiated procedure and is based solely on selective information provided by this competitor. Said competitor has meanwhile definitely waived its civil complaint in the dispute. At the introductory hearing on 6 December 2023, the Court of First Instance Oost-Vlaanderen, Ghent Division, has set a calendar for exchange of submissions. The DEME companies will now, for the first time, have the chance to submit substantive arguments regarding the charges brought by the Public Prosecutor. This means that so far, there has been no assessment of the case on the merits, which will require extensive debate, both in written submissions and oral arguments. In the current circumstances, it is therefore premature to speculate on the outcome of these proceedings. It is however clear that there is no longer any risk of payment of civil damages against the claimant, which, as stated above, has definitively waived its civil complaint.

The Group takes care that all its entities respect the laws and regulations in force, including the compliance rules.

Note 26 – Working capital

For the year ended 31 December

Operating working capital (OWC) is net working capital (current assets less current liabilities), excluding interest-bearing debt and cash and cash equivalents and financial derivatives related to interest rate swaps and including other non-current assets and non-current liabilities (if any) as well as non-current financial derivatives (assets and liabilities), except for those related to interest rate swaps.

Focus of the DEME Group is to find the balance between the operating working capital on the one hand and the net cash being the difference between cash and cash equivalents and short-term debt on the other hand. In the contracting business operating working capital is difficult to monitor as each project is different, not only in size and capital needs but also and more specifically in the way the Group is paid by its customers. Most of the turnover is paid with an advance payment at the beginning of the project followed by milestones payments after execution of the work and approval by the client.

When the operating working capital is under pressure and when it has to be increased, the Group can either grow its assets or reduce its liabilities. The Group can negotiate shorter milestones and payment terms with the customers or negotiate longer payment terms with the suppliers, however without putting a strain on the relationships with them. The Group can limit the non-project-related expenditure and review and limit the capital expenditure or sell excess equipment and convert them into working capital.

For the financing of its working capital needs, DEME sources its short-term funding through a commercial paper programme and through revolving credit facilities. At year-end 2023 the Group had an outstanding issued amount of commercial paper for 30 million euro (2022: none). DEME has the possibility to issue commercial paper for amounts up to 250 million euro in total, compared to a lower amount of 125 million euro last year. In total, 110 million euro of unused credit facilities were available at the end of 2023, for general corporate purposes (2022: 125 million euro). Besides short-term financing also long-term financing can be considered to fund raising working capital needs.

Shareholders

CFE NV, DEME's previous shareholder before the public listing, is considered to be a fellow subsidiary as from 30 June 2022, date of the partial demerger of CFE NV. CFE NV and DEME Group NV have both Ackermans & van Haaren as their main shareholder.

Since 2001, DEME has a service agreement with Ackermans & van Haaren NV for services rendered which is subject to indexation on a yearly basis. The service agreement covers specialised advice delivered by Ackermans & van Haaren NV. The service agreement was identical to the one DEME had with CFE NV but that ended for CFE NV after the partial demerger mid-2022. The remuneration due by DEME in 2023 towards the only remaining party, Ackermans & van Haaren, upon the conditions of the contract amounts to 1,433 thousand euro (2022: AvH:1,323 thousand euro and CFE: 662 thousand euro).

DEME also received incoming invoices of its shareholder and/or fellow subsidiary for an amount of 555 thousand euro, a.o. relating to a maintenance contract for central heating & air conditioning and for its presence on business specific events (2022: 1,106 thousand euro, mainly related to the IPO).

On the other hand, DEME invoiced around 660 thousand euro to its shareholder and fellow subsidiary, mainly related to IT licences, tax and accounting consulting services (2022: 164 thousand euro).

DEME recently constructed a new office building and is still building a visitor pavilion on the site of its headquarters in Zwijndrecht. Execution of works is done by a subsidiary of CFE NV. At 31 December 2023 invoices received for an amount of 12,440 thousand euro are recognised as buildings within 'property, plant and equipment' and still 3,760 thousand as assets under construction (2022: 6,221 thousand euro).

Key management personnel

DEME Group NV has a "one tier" governance structure consisting of a Board of Directors (as collegiate body). The Board of Directors is vested with the power to perform all acts that are necessary or useful for the realisation of the Company's corporate object, except for those actions that are specifically reserved by law for the Shareholders' Meeting.

On 29 June 2022, the Board of Directors has delegated the daily management of the Company from the Executive Committee to the CEO. The CEO is assisted in the exercise of its powers by the Executive Committee, which operates as an advisory committee (separate from the Board of Directors). The Executive Committee, chaired by the CEO, is responsible for discussing the general management of the Company.

For his role as Executive Director, Luc Vandenbulcke received a fixed and variable remuneration of 1,986 thousand euro in 2023 (2022: 1,797 thousand euro). The 2023 annual salary includes an exception of an early single and double holiday payment settlement upon transition towards self-employed status. Representatives who are members of the Board of Directors, Audit Committee and Remuneration Committee are only remunerated since the public listing of the Group. As such the comparative for 2022 below only refers to a 6 month-period whereas 2023 figures are included for a 12 month-period.

Note 29 – Auditor remuneration

For the year ended 31 December

An overview of the total remuneration paid to the auditors by DEME Group NV and its consolidated subsidiaries is presented below. A distinction (both in absolute figures and in percentage) is made between fees paid by the Group to the statutory auditor of DEME Group NV, EY, and fees paid to other audit firms.

2023	EY			Others
(in thousands of euro)	Amount	%	Amount	%
Audit fees	1,176	43.2%	1,549	56.8%	2,725
Tax advisory services	222	8.9%	2,284	91.1%	2,506
Other non-audit services	127	9.1%	1,273	90.9%	1,400
	1,525	23.0%	5,106	77.0%	6,631

The amount of additional (non-) audit services provided by the statutory auditor and persons professionally related to him are in line with article 3:64 and 65 of the Code of companies and associates and approved by the Audit Committee in advance. They mainly relate to rendered tax services and ad-hoc attestations. In 2022 they also included additional audit works performed relating to the IPO of DEME.

The other (non-) audit services, performed by other auditors not being the statutory auditor of DEME Group NV, mainly relate to tax services rendered and consulting services. Entering two new geographies, like US and Taiwan, resulted in an increase in tax advisory services issued (both region and project specific advice, transfer pricing etc.). As the procurement transformation project is final and a new procurement system is rolled out (including a compliance component), the consultancy services for implementing this tool within the Group enormously decreased compared to last year.

We analysed the calculation of the percentage of completion used to recognize revenue and margin for a sample of projects.

• We compared the financial performance of projects against budget and historical trends
• We completed site visits for certain projects to observe the stage of completion of these projects and discussed the status with site personnel as well as complexities of the project that could impact its total forecasted cost
• We analysed correspondence with customers around variation orders and claims and assessed whether this information was consistent with the estimates made by the management
• We inspected key clauses impacting the (un)bundling of contracts, delay penalties, bonuses or success fees. We assessed whether these key clauses have been appropriately reflected in the amounts recognized in the Consolidated Financial Statements
• We assessed the adequacy of the information disclosed in the summary of material accounting principles, note 1 and note 13 to the Consolidated Financial Statements

Uncertain tax positions

Description of the key audit matter

DEME operates its global business across a variety of countries subject to different tax regimes. The taxation of its operations can be subject to judgements and might result in diverging views of local tax authorities and that may span multiple years to get resolved. Where the amount of tax payable is uncertain, management establishes an accrual based on its best estimate of the probable amount to settle the liability. This is a key audit matter because management exercises significant judgement in assessing the liability for uncertain tax positions at balance sheet date and changes to these estimates could give rise to important variances.

Summary of the procedures performed

• We obtained an understanding of the process in respect of accounting for (deferred) taxes and assessed the design and the implementation of the related key internal controls
• We assessed the estimated probability of the identified tax risks and challenged management's estimates of the potential outflows trough management inquiry and inspection of the supporting documentation (changes in tax legislation, correspondence with tax authorities and tax advisors, available rulings)
• We involved our tax professionals to assist us in the evaluation of management's assumptions and application of relevant tax laws and regulations in the assessment of the Group's uncertain tax positions
• We assessed the adequacy of the information disclosed in the summary of material accounting principles and note 11 to the Consolidated Financial Statements

Responsibilities of the Board of Directors for the preparation of the Consolidated Financial Statements

The Board of Directors is responsible for the preparation of the Consolidated Financial Statements that give a true and fair view in accordance with IFRS and with applicable legal and regulatory requirements in Belgium and for such internal controls relevant to the preparation of the Consolidated Financial Statements that are free from material misstatement, whether due to fraud or error.

As part of the preparation of Consolidated Financial Statements, the Board of Directors is responsible for assessing the Company's ability to continue as a going concern, and provide, if applicable, information on matters impacting going concern, The Board of Directors should prepare the financial statements using the going concern basis of accounting, unless the Board of Directors either intends to liquidate the Company or to cease business operations, or has no realistic alternative but to do so.

Our responsibilities for the audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance whether the Consolidated Financial Statements are free from material misstatement, whether due to fraud or error, and to express an opinion on these Consolidated Financial Statements based on our audit. Reasonable assurance is a high level of assurance, but not a guarantee that an audit conducted in accordance with the ISA's will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and 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 Consolidated Financial Statements.

In performing our audit, we comply with the legal, regulatory and normative framework that applies to the audit of the Consolidated Financial Statements in Belgium. However, a statutory audit does not provide assurance about the future viability of the Company and the Group, nor about the efficiency or effectiveness with which the Board of Directors has taken or will undertake the Company's and the Group's business operations. Our responsibilities with regards to the going concern assumption used by the Board of Directors are described below.

As part of an audit in accordance with ISA's, we exercise professional judgment and we maintain professional skepticism throughout the audit. We also perform the following tasks:

• identification and assessment of the risks of material misstatement of the Consolidated Financial Statements, whether due to fraud or error, the planning and execution of audit procedures to respond to these risks and obtain audit evidence which is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting material misstatements resulting from fraud is higher than when such misstatements result from errors, since fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control

Independent auditor's report

Independent auditor's report to the General Assembly of DEME Group NV for the year ended December 2023.

In the context of the statutory audit of the 'Consolidated Financial Statements' of DEME Group NV (the 'Company') and its subsidiaries (together the 'Group'), we report to you as statutory auditor. This report includes our opinion on the consolidated statement of financial position as at 31 December 2023, consolidated statement of income, consolidated statement of comprehensive income, consolidated statement of changes in equity and the consolidated statement of cash flows for the year ended 31 December 2023 and the disclosures including material accounting policy information (all elements together the 'Consolidated Financial Statements') as well as our report on other legal and regulatory requirements. These two reports are considered one report and are inseparable.

We have been appointed as statutory auditor by the shareholders' meeting of 29 June 2022, in accordance with the proposition by the Board of Directors following recommendation of the Audit Committee and following recommendation of the workers' council. Our mandate expires at the shareholders' meeting that will deliberate on the Consolidated Financial Statements for the year ending 31 December 2024. We performed the audit of the Consolidated Financial Statements of the Group during two consecutive years.

Report on the audit of the Consolidated Financial Statements

Unqualified opinion

We have audited the Consolidated Financial Statements of DEME Group NV, that comprise of consolidated statement of financial position on 31 December 2023, consolidated statement of income, consolidated statement of comprehensive income, consolidated statement of changes in equity and the consolidated statement of cash flows of the year and the disclosures ,including material accounting policy information, which show a consolidated balance sheet total of € 4.760.058 thousand and of which the consolidated income statement shows a profit for the year (Share of the Group) of € 162.762 thousand.

In our opinion, the Consolidated Financial Statements give a true and fair view of the consolidated net equity and financial position as at 31 December 2023, and of its consolidated results for the year then ended, prepared in accordance with the International Financial Reporting Standards as adopted by the European Union ("IFRS") and with applicable legal and regulatory requirements in Belgium.

Basis for the unqualified opinion

We conducted our audit in accordance with International Standards on Auditing ("ISA's") applicable in Belgium. In addition, we have applied the ISA's approved by the International Auditing and Assurance Standards Board ("IAASB") that apply at the current year-end date and have not yet been approved at national level. Our responsibilities under those standards are further described in the "Our responsibilities for the audit of the Consolidated Financial Statements" section of our report.

We have complied with all ethical requirements that are relevant to our audit of the Consolidated Financial Statements in Belgium, including those with respect to independence.

We have obtained from the Board of Directors and the officials of the Company the explanations and information necessary for the performance of our audit and we believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Key audit matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the Consolidated Financial Statements of the current reporting period.

These matters were addressed in the context of our audit of the Consolidated Financial Statements as a whole and in forming our opinion thereon, and consequently we do not provide a separate opinion on these matters.

Revenue recognition and project accounting

Description of the key audit matter

For the majority of its contracts (hereafter the "contracts" or the "projects"), the Group recognises revenue and profit on the stage of completion based on the proportion of contract costs incurred for the work performed to the balance sheet date, relative to the estimated total costs of the contract at completion. The recognition of revenue and profit therefore relies on estimates in relation to the forecasted total costs on each contract. Cost contingencies may also be included in these estimates to take specific uncertain risks into account, or disputed claims against the Group, arising within each contract.

The revenue on contracts may also include variation orders and claims, which are recognised on a contract-by-contract basis when the additional contract revenue can be measured reliably in line with the IFRS.

Revenue recognition and contract accounting often involves a high degree of judgment due to the complexity of projects, uncertainty about costs to complete and uncertainty about the outcome of discussions with clients on variation orders and claims. This is a key audit matter because there is a high degree of risk and related management judgement in estimating the amount of revenue and associated profit or loss to be recognised, and changes to these estimates could give rise to important variances.

Summary of the procedures performed

• We obtained an understanding of the process related to the contract follow up, the revenue and margin recognition and when applicable, the provisions for losses at completion, and we assessed the design and the implementation of the related key internal controls, including management review controls
• Based on quantitative and qualitative criteria, we selected a sample of contracts to assess the most significant and complex project estimates. For this sample, we obtained an understanding of the current status and history of the projects and discussed the judgments inherent to these projects with senior executive and financial management. We analysed the differences with prior period project estimates and assessed consistency of reporting of the status of the projects with the actual developments of the project during the year

This type of vessel is used for connecting offshore structures through intra-array (inter-turbine) cables and consequently bringing the offshore produced energy ashore through export cables. Beside cable laying activities, the vessel can be employed in a wide range of associated activities, such as offshore support, ploughing, subsea rock installation, offshore construction, floating windpark installation etc. The vessels are equipped with one or more turning tables allowing to continuously load and install very long cables.

MW

Megawatt

MWh

Megawatt hour- A megawatt hour (MWh) equals 1,000 kilowatts of electricity generated per hour and is used to measure electric output.

MW beneficial ownership

The amount of economic ownership of wind energy from offshore concessions in operation.

MW installed foundations

MW installed foundations (contributed capacity) is calculated counting total number offoundations installed by DEME during the reporting period (between January 1 and December 31) and multiplying by the corresponding turbine capacity. The turbine capacity is also called the rated power of the turbine. It is the power that the turbine generates for wind speeds above the "rated"level. Each installed turbine has a specific rated power, expressed as a number of MW.

MW installed wind turbines

The total turbine capacity installed by DEME during the reporting period (between January 1st and December 31st). The turbine capacity is also called the rated power of the turbine. It is the power that the turbine generates for wind speeds above the "rated"level. Each installed turbine has a specific rated power, expressed as a number of MW.

Nature-based solutions

Solutions that are inspired and supported by nature , which are costeffective, and simultaneously provide environmental, social and economic benefits and help build resilience.

Net financial debt

Net financial debt is the sum of current and non- current interestbearing debt (that includes lease liabilities) decreased with cash and cash equivalents.

NOx

Nitrogen oxide (NO) and nitrogen dioxide (NO2) are collectively known as nitrogen oxides (NOx), which are a group of poisonous, highly reactive gases. NOx form when fuel is burned at high temperatures and are air pollutants that cause a local environmental impact, such as the formation of acid rain,respiratory health effects.

Offshore installation vessel (Floating or jack-up units)

An afloat or self-elevating vessel used for the installation and maintenance of offshore wind farms or any other offshore construction works. A jack-up vessel or self-elevating unit is a selfpropelled mobile platform consisting of a buoyant hullfitted with a number of movable legs, capable ofraising its hull over the surface of the seabed. Once on location the hull is raised to the required elevation above the sea surface supported to the sea bed, leading to stable working conditions independent of any swell on the sea. Unlike a self-elevating vessel, a floating not lift herself above the sea surface, which means that the vessel is not and the seabed conditions.

Offshore installation vessel can dependent on the water depths

Operating working capital (OWC)

Operating working capital (+ is receivable,-is payable) is net working capital (current assets less current liabilities), excluding interest-bearing debt and cash & cash equivalents and financial derivatives related to interest rate swaps and including other non-current assets and non-current liabilities (if any) as well as non-current financial derivatives (assets and liabilities), except for those related to interest rate swaps.

OpEx

OpEx are all the operating expenses of the Group. SG&A expenses incurred through normal business operations are also included except for personnel expenses, depreciation, amortisation & impairment costs and other operating expenses.

Opportunity and Risk Management (ORM) system

A system for the properidentification, assessment and management ofrisks and opportunities with respect to tendering, preparation and execution of projects.

Orderbook

TheGroup's orderbook is the contract value of assignments acquired as of31 December but that is not yet accounted for as turnover because of non-completion.The orderbook also includes theGroup's share in the orderbook ofjoint ventures, but not of associates.Contracts are not included in the orderbook until the agreement with the customeris signed. A letter of award is not sufficient to include the contract in the orderbook according to theGroup. Additionally financial close must be reached when projects will be executed in 'uncertain' countries before including them in the orderbook. 'Uncertain countries' are identified at the discretion of theExecutiveCommittee.

OSS (offshore substation)

Offshore substations are dedicated platforms that collect energy generated from offshore wind farms and transferit to shore through an export cable. The systems that collect and export the power generated by turbines through specialised submarine cables are an essential component of offshore wind farms, especially at large, multi-megawatt sites.

PM

Particle pollution — also called particulate matter(PM) — is made up of particles (tiny pieces) of solids orliquids that are in the air. These particles may include dust, dirt, soot, smoke or drops ofliquid which have a local environmental impact and can be harmfulfor health when breathing them in.

PPP

SG&A costs

Sales, General and Administrative expenses. All expenses made at DEME levelrelated to Supporting Services Departments and Sales and Tender organisation. As such these expenses are not directly linked to any projects or type of equipment. They are expenses of a non-operational nature.

SOx

Sulphur oxides (SOx) are a group of molecules made of sulfur and oxygen atoms, such as sulfur dioxide (SO 2 ) and sulfur trioxide (SO 3). Sulfur oxides are air pollutants that cause a local environmental impact, such as the formation of acid rain,respiratory health effects.

Time To

Internal DEME system for career development. The Time To programme allows to have a formalfeedback moment between Employee and Manager to capture all this feedback and discussions regarding your career and development.

Trailing suction hopper dredger (TSHD)

A self-propelled vessel, which fills its hold or hopper during dredging activities. The vessel is equipped with either single or twin trailing suction dredge pipes that extend to the sea bottom. While trailing at low speed, using centrifugal pumps, the dredged materials are stored into the hopper. Afterwards the vessel can sail long distances and empty its hold by opening bottom doors or valves (dumping), by rainbowing or by pumping its load off ashore through the use offloating -and land pipelines. This kind of dredger, which can operate independently, is mainly used in open waters:rivers, canals, estuaries and the open sea.

WW LTIFR ('Safety thermometer')

The Worldwide Lost Time Injury Frequency Rate (Worldwide LTIFR) is the metric reflecting accidents of DEME employees and DEME temporary employees involving work incapacity (≥ 24 hours or ≥ 1 shift) multiplied by 200,000 and divided by the number of hours worked. The 'Worldwide' method is a risk-based method that combines 'risk level rate' (= event that resulted in the injury) and 'injury rate' (= type of injury). To determine if an incident scores as 'Worldwide', the 'risk level rate' and 'injury rate' are multiplied.

Zero carbon fuels Fuels that emit no carbon dioxide when consumed.

Zero-emission equipment/cars

Vehicles that use a propulsion technology which does not produce internal combustion engine exhaust or other carbon emissions when it operates, such as electric vehicles.

Macroeconomic developments			Capital-intensive nature of industry — continued
DEME is a worldwide player and consequently vulnerable to developments that may arise on the macroeconomic level. Our activities are primarily driven by the growth of the global population, (particularly the trend to live near the coast and major rivers) , the growth of	Part of the demand for DEME's services reflects changes in the economic growth rates of the region. Demand is also dependent on developments in the various industries we serve such as new infrastructure related to the energy transition.	Through geographical diversification, a qualitative customer portfolio and a vast network built up over decades, DEME tries to secure business continuity. However, given the complexity and diversity of our activities worldwide, it is not possible to fully anticipate	The expansion and development of DEME's business can require additional capital, which it may obtain through debt and/or equity financing to fund investments.	Additional debt financing, if obtained, may expose DEME to additional covenants imposed by financial institutions or lenders.
the worldwide economy and the need for suitable infrastructure to accommodate this (for example port extensions and maritime access routes). This increase in international trade is in turn leading to the ever-increasing size of tankers and containerships, which is an important factor for our dredging business. This results in more investment in deepening and widening access channels and berths.	In addition, a considerable portion of DEME's activities are driven by governmental policies and public spending. Therefore, DEME is particularly exposed to the level of economic activity and susceptible to changes in the external economic conditions in each of the markets in which it is active.	every major change in the market conditions and the impact these could have on our business.	Specific characteristics of DEME's vessels and other equipment, and the limited number of players in the global markets in which DEME is active (e.g. dredging, offshore wind, etc.) could have a negative impact on the valuation of these assets in the event they would be sold.	A negative impact on the fair value valuation of the fleet and other equipment can give rise to a lower value, and as such, impact the financial statements of the Group.
Additionally, the surging demand for energy			Competition
and targets to achieve the energy transition and climate neutrality, and the scarcity of minerals and raw materials, are other key drivers.			The sectors in which DEME operates are highly competitive, with DEME facing both local and international competition.	The dredging industry is cyclical in nature (in terms of capital dredging works), and price pressures are indeed being witnessed, particularly during low cycles.
Geopolitical developments			Competitive factors include price, service quality, scope of activities (incl. geographically),	As fleet utilisation is important, DEME's competitors may adopt a strategy of tendering for projects at lower prices. This aggressive pricing could result in DEME having to lower its price or improve credit terms significantly in order to secure projects, thereby reducing its gross profit margins and cash flow.	competitive pressure to some extent. At present, DEME has a modern and competitive fleet as a result of a multi year investment programme.
Given the global footprint of DEME's operations, we are sometimes exposed to elevated risks relating to political and/ or social instability (including war, civil unrest, armed conflict, terrorism, hostage taking, piracy, extortion and sabotage).	Any such events could materially adversely disrupt DEME's operations or affect its business, personnel, equipment and vessels.	DEME aims to mitigate these risks by constantly monitoring the situation and security in those politically unstable areas where projects are being performed. Protectionism is alleviated when and where possible by means of local partnerships. Moreover, DEME may suspend a project in order to bring its personnel, equipment and vessels to safety. DEME's assets (primarily its vessels) can also be swiftly rerouted to an alternative, safe location.	reputation, experience and environmental impact, as well as the availability of favourable payment and credit terms.
Capital-intensive nature of industry			Investments in unproven markets
The capital-intensive nature of the industry in which DEME is active calls for major investments (specifically in dredging and offshore vessels but also in concession activities).	Investment projects are often highly complex from both a technical and financial point of view. Furthermore, there is a long period of time between the moment that the decision to invest is taken and the mobilisation of the financing upto when the new vessel is delivered. This can give rise to lost opportunities or underutilisation should the market conditions have changed in the meantime. Concession activities and project development may also be subject to uncertainty as to whether the necessary financing will be obtained.	To remain competitive, DEME invests in new vessels and develops, finances and implements groundbreaking technologies. During the construction of new vessels we always work closely with the shipyard to make sure we maintain a tight control of the costs involved.	In its business development and diversification efforts, DEME is investing in industries and markets that are not yet established and at least initially, they can rely on unproven technology such as deep-sea mineral harvesting (GSR) and green hydrogen (DEME Concessions).	Investing in unproven markets can give rise to high research and development costs, impacting the financial position of the Group. Moreover, new industries or assets can become obsolete or uncompetitive in view of current market circumstances and evolving standards.

As a result of the capital-intensive nature of the industry, DEME has had and may continue to have a significant amount of borrowing costs, but these are always closely monitored by management and the Board of Directors.
The value of the fleet is continuously monitored by DEME's Technical Department using internal and external information (e.g. valuation reports…). At every reporting date, the fair value of the fleet is compared with the book value and if necessary, an impairment is recorded.
The large amount of capital required for the sectors in which DEME is active, the resulting limited number of players, and DEME's leading position in both the dredging and offshore wind markets, ease potential competitive pressure to some extent. DEME's ability to compete will largely depend on being able to continue to innovate and provide state-of-the-art solutions to its customers. DEME needs to keep up with evolving technologies (both hardware and software), and ensure it has advanced technology and equipment to retain its market share, reputation and position. At present, DEME has a modern and competitive fleet as a result of a multi year investment programme.
DEME relies largely on its ability to continue to innovate and provide state-of-the-art solutions to its customers, also in unproven markets. Financial investments in these fledgling markets, which are not yet generating income, are covered by the cash flows arising from the other operational segments of the Group.

Business risks

Operational risks can lead to possible cost overruns, particularly for those projects with fixed-price contracts or with limited price escalation provisions, where the actual costs may exceed the initial estimation made by DEME due to unanticipated costs (e.g. resulting from supply price increases, additional work, delays in performance, etc.). Such additional costs cannot always be passed on to the customer, resulting in DEME bearing all, or at least a portion of these costs. Depending on the size of a project, variations from the estimated costs due to performance could have an adverse effect on DEME's financial performance, operational results, or cash flows. In particular, projects based on new designs may entail higher risks of cost overruns because DEME may be less able to make a proper cost estimate beforehand, especially when it ventures into new business segments for the first time. Delays (due to possible internal and/or external factors) in meeting delivery performance	The ORM Department deploys its ORM system for the timely identification, assessment and management of risks and opportunities with respect to tendering, preparation and the execution of projects. Opportunities and risks are continuously monitored so that timely decisions and necessary actions can be taken. There is also a Risk Committee, composed of the CEO, CFO and members of the Executive Committee, or any person appointed by the latter responsible for the relevant segment or any person appointed by the latter, complemented with non-executive directors and/or any other persons designated by the Board of Directors. As well as assisting the CEO in his task of assessing risk management matters, the Committee approves all binding offers related to major contract awards. The Risk Committee reports regularly to the Board of Directors on the performance of its duties and identifies any matters for		During a project, DEME may be confronted with certain other general risks which are, directly or indirectly, caused by factors that are inherent to DEME's business (e.g. marine engineering contracts).	DEME may be subject to increased project costs due to possible non-working days, a delay in the delivery of the works, injuries to employees or third parties, damage to equipment/vessels or those of third parties, as a result of any of the following factors: — the determination of nature and composition of the soil and/or specific site conditions; — weather conditions and extreme events including storms, tsunamis, earthquakes, etc.; — wear and tear of equipment; — technical or mechanical incidents and breakdowns that may influence the performance of the vessels or cause damage to own or third-party equipment; — the concept and engineering of the project, as well as the assessment of the technical suitability of the equipment; — changes to the regulatory framework during the course of the contract; — the relationship with and reliance on subcontractors, suppliers and (joint venture) partners, particularly in the context of Engineering, Procurement, Construction and Installation (EPCI) projects.

This includes third-party risks in the form of poor performance or non-performance of subcontractors, suppliers, vendors, joint venture partners or other parties, which could affect DEME's ability to execute its projects as planned. For instance, this could happen when substitute manufacturers are limited, especially for those making specialised equipment. Potential penalties or damages, additional costs etc. may arise from not meeting performance requirements. These could be due to quality standards, the contract period, or cost overruns resulting from not complying with warranty obligations (e.g. responsibility for maintenance etc.). Adverse effects on DEME's business could result from failure to comply with any changes in the applicable regulations and legislation, for example, safety and social obligations vis-à-vis subcontractors. There is also the potential of unlimited penalties or damages to be paid as some contracts, in particular public contracts, may not have limitation of liability clauses.			DEME requires various approvals, licences, permits and certificates to operate its business. These have to be obtained, maintained and renewed.	Without the required approvals, licences, permits and certificates it may not be possible to operate its business. For instance, Belgian contractors must hold a "Certificate of Recognition" which has to be renewed every five years. Comparable requirements exist for all of DEME's activities worldwide. With respect to the fleet, vessels must fly a flag based on the completion of a registration procedure and a technical survey. Upon the successful completion, the vessel is granted a "Certificate of Registry".

DEME tries to manage all those risks through its project management systems, including taking out appropriate insurance policies.

DEME makes sure that all of its certificates are kept up to date and that it meets international legal and other local mandatory QHSE requirements.

Additional certificates are even obtained to ensure that DEME's QHSE standard is higher than industry requirements.

DEME holds an ISO Group Certificate, which includes more than 50 of our operational and commercial entities. All certified entities are compliant with the following standards:

ISO 9001 Quality Management Systems ISO 14001 Environmental Management Systems ISO 14064 Reporting ISO 45001 Health and Safety Management Systems ISO 50001 Energy Management Systems

In addition to ISO, the QHSE Management System is compliant with other specific standards.

Furthermore, vessels are subject to classification rules which are designed to protect vessels, crews and the environment among others.

As a project developer and concession holder, DEME focuses on renewable energy, marine infrastructure, ports, dredging, green hydrogen and other special projects.	The process from the first idea until the actual completion could entail an extensive period of time, even several years. This means that considerable costs could be incurred, and a lot of time may be spent on a potential new project, even though there is no guarantee that the project will eventually materialise. For example, obtaining a concession from the relevant governmental authority can be a risk,	Within DEME there is a Technical Committee overseeing the Group's activities, as well as a special Technical Committee for DEME Concessions in particular.

For DEME Offshore's projects and in view of EU Taxonomy reporting, DEME has chosen the IPCC's RCP 8.5 scenario to serve as the baseline climate scenario. This is referred to as chronic physical climate-related risk

Carbon taxes do not only result in additional direct costs but also increase prices for procured products & services (e.g. steel, concrete, etc.).	DEME has a climate transition plan in place which focuses on increased operational and technical energy efficiency and the shift to alternative fuels, which emit fewer GHG emissions. These measures will lower the exposure and impact from carbon taxes and emissions trading schemes. The impact of potential costs is subject to pass-through clauses in the contract which can be different for every project.
More extreme weather conditions could result in more operational downtime.	DEME continuously monitors and assesses economic and climate-related circumstances to anticipate, limit or avoid any impact on its financials. Damage to assets as a result of extreme weather conditions such as storms are covered by casualty insurance policies.
Ocean acidification could have a limited impact on offshore projects. For example, as the pH of the water decreases (and the acidity increases) the corrosion rate of a wind turbine structure increases, which could result in the replacement of sacrificial anodes or an increase in ICCP (Impressed Current Cathodic Protection) current cathodic protection. On the other hand, DEME identifies the rising sea level rise as an opportunity for its dredging activities.	While designing wind turbine foundations, DEME takes parameters looking at chronic physical climate-related risks such as changing wind patterns and ocean acidification into account.

These environmental risks can be broken down into two main components: — Firstly, the environmental companies within the Group must by the very nature of their activities – soil and sludge remediation – deal with dangerous and harmful substances. The contamination types and the technologies used to cope with them are not always free of risks. — Secondly, the Infra business segment of DEME – active in marine infrastructure – relies heavily on natural resources such as sand. Government bodies may impose restrictions on the use of certain natural resources or may demand the reuse of certain resources. The customer for example, will either impose minimum levels of reuse or favour tenders which reuse the most material. As a consequence, DEME has to consider the circular economy and find ways to optimise the recycling of materials.	It is also DEME's ambition to fundamentally contribute to sustainable solutions for the global environment, societal and economic challenges faced in the world today. In line with this, DEME is continuing its ambitious strategy to expedite the energy transition and its sustainability ambitions are also embodied in its modern, innovative fleet. Additionally, DEME aims to play a role in the move towards the circular economy by providing integrated circular solutions for soil remediation, brownfield development, environmental dredging and sediment treatment.

Disturbance of the environment

Dredging, land reclamation, offshore works, infrastructure and environmental projects or deep-sea harvesting are activities which impact the environment and face specific environmental risks.

Financing			Market risk: exchange rate risks — continued
To finance its investments and activities, DEME frequently makes use of external financing sources, both for short- and long-term financing.	The extent of leverage may expose the Group to various risks, including increasing its vulnerability to downturns or adverse changes in general economic, industry or competitive conditions and government regulations. This requires a substantial portion of its cash flows from operations to be dedicated to the payment of principal loans and interest on the Group's indebtedness, therefore reducing its ability to use its cash flows to	DEME aims to maintain a healthy balance between consolidated net equity and consolidated net debt.

DEME seeks to diversify its financing resources (though only with banks with which it has a longstanding relationship and with good investment grade credit ratings) and to spread the maturity dates.	DEME is exposed to risks associated with fluctuations of prices for raw materials and energy. These are essential for the performance of its activities and as such are an important element of its costs.	The prices at which DEME can purchase certain raw materials (e.g. steel) or energy (fuel oil or LNG) may fluctuate significantly according to local and international market conditions (e.g. shortages, market price volatility, currency	DEME also hedges against oil price

For its financing, DEME is facing an interest rate risk that can be defined as the extent to which the results or value of a financial transaction are affected by a change in market interest rates.

with foreign currencies subject to local restrictions, use is made - where possible - of non-deliverable forward (NDF) hedging.

Financial risks

Some contracts allow cost increases for raw materials and energy to be passed on to the customer by means of price-review mechanisms.

DEME also hedges against oil price fluctuations by entering into forward contracts. Though, this practice becomes more costly and therefore unsuitable when it spans a lengthy amount of time or when quantities cannot be estimated reliably.

DEME aims to minimise the credit risks of its customers by examining their solvency prior to finalising the contract and putting the required payment guarantees in place (including credit insurance policies with public service credit insurers such as Credendo and private credit insurers, bank guarantees and through letters of credit). But it is not possible to entirely exclude the credit risks associated with customers.

A large part of the consolidated turnover however, is realised through public or semi-public sector customers. Therefore, the level of counterparty risk is limited because these entities represent a substantial proportion of our customers.

To contain the remaining risk, DEME constantly monitors its outstanding trade receivables and adjusts its position if necessary.

Description of the risk	Potential impact	Risk management and control
Market risk: price and commodity risk — continued
DEME is exposed to counterparty risks when placing/investing its available liquidities and when subscribing to financial derivatives.	Financial institutions can go into default or be declared bankrupt and in turn, put our invested assets at risk.	DEME has a policy to minimise counterparty risk by avoiding concentrations of these and in such matters working only with banks with which it has a longstanding relationship and with good investment grade credit ratings, but it is not possible to entirely exclude credit risks from financial counterparties.
Liquidity risks
Although DEME operates strict financial policies and ensures that there is a diversity of sources of finance and repayment periods, not all negative effects on the cash flow and liquidity can be avoided if customers don't meet their payment obligations for example, if DEME doesn't manage to arrange adequate external financing subject to acceptable conditions. This can result in a negative impact on the activities, financial situation and results of DEME.	All these factors might result in DEME having difficulties to comply with its credit facility covenants. If its future cash flows from operations and other capital resources would be insufficient to honour its payment obligations or to fund its liquidity needs, DEME may be forced to adapt its business activities and capital expenditures, sell assets, obtain additional debt or equity capital, restructure or refinance all or a part of its debt on or before maturity, or for opportunities such as acquisitions.	The liquidity risk is limited by spreading borrowing among several banks, agreeing a variety of repayment periods and also by mitigating the credit risk. Moreover, DEME mainly invests in equipment with a long lifespan, which is written off over several years and for that reason, DEME seeks to structure a substantial part of its debts as long-term debt.

DEME always seeks to monitor and adapt to changes in the legal systems, regulatory controls, customs and practices in the jurisdictions where it operates.

Description of the risk	Potential impact	Risk management and control
Compliance with, and changes to laws
DEME is active in a large number of countries in all parts of the world and is subject to a wide variety of legislation and regulations in each of the jurisdictions in which it operates. And it can be the case that DEME incurs substantial costs in order to comply with these regulations.	The regulations to which DEME is subject vary from jurisdiction to jurisdiction and may change over time. This can include changes to export, import and transit inspections, excise, rates and quotas, income tax, withholding tax, VAT and other tax, environmental legislation, checks on international trade and currency, and workplace and social security policies.	controls, customs and practices in the jurisdictions where it operates.

DEME is committed to responsible business practices and has formulated internal policy with the objective to execute all of its activities with integrity and zero tolerance with regard to corruption.

DEME operates a global Compliance Programme (through, for instance, DEME's Code of Ethics & Business Integrity and the Group's existing policies, procedures, training, whistle-blower hotline, IT tools, internal controls and risk management in relation to antitrust, anti-money laundering, anti-bribery or anti-corruption laws, regulations and sanctions, including the monitoring thereof by DEME's Compliance Department).

But there can be no assurance, however, that such codes, policies and procedures are always being applied by employees, agents, third-party providers or any other representatives involved in DEME's business.

Compliance with, and changes to environmental, health and safety laws

DEME's business involves certain inherent risks related to the health and safety of employees, subcontractors and others.

DEME could incur substantial liability in the event of accidents, exposure to hazardous substances, spillages or other events resulting in injury or death, even if the event is not DEME's fault.

Furthermore, in some of the countries where DEME works, the activities may be affected by social and/or political instability (terrorism, armed conflict, seizure of bank accounts etc.), as well as prone to malicious and/or criminal acts (vandalism, theft, physical attacks, kidnapping, piracy, etc.).

DEME identifies risks of accidents, or injury and health impacts and introduces the appropriate mitigation measures. Though in the event of accidents, injuries to employees or subcontractors cannot be entirely excluded.

The QHSE slogan is "Zero accidents and zero environmental incidents". The company's priority is, and remains the wellbeing of employees and subcontractors by creating a high quality, healthy, safe and eco-friendly working environment.

QHSE is always on the agenda of DEME's Management Team, Executive Committee and Board of Directors' meetings.

As well as this, each employee has a "Stop Work Authority": the right and obligation to stop any activity that is deemed to involve unacceptable risks.

Key Performance Indicators (KPIs) are in place at all levels of the organisation to follow up on QHSE performance.

Legal and regulatory risks

Compliance with, and changes to environmental, health and safety laws — continued
DEME's business involves certain inherent risks related to the environment.	In certain jurisdictions, incidents resulting from dredging, land reclamation, offshore works, infrastructure and/or environmental activities (for instance, contamination of air, water and soil) require the contractor to clean up after the works and bear the cost thereof.	It is DEME's policy to strictly abide by and comply with all the applicable legislation and regulations in every jurisdiction in which DEME is active.
Tax risks
DEME operates in a range of countries subject to different tax regimes. DEME's effective tax rate and tax liability are based on the application of current income tax laws, regulations and tax treaties. From time to time, various governments make substantive changes to tax rules and the application of rules, including changes potentially impacting the Group's ability to defer taxes on international earnings. In addition, DEME is regularly subject to audits of its income tax returns and VAT declarations by the tax authorities in the various countries in which DEME operates.	Significant judgment is required to determine tax liabilities worldwide, and this is partly because tax laws and regulations do not always provide clear and definitive guidelines. DEME's effective tax rates and tax exposure could potentially be affected by a multitude of reasons. These include changes in the composition of its earnings in countries or jurisdictions with higher or lower tax rates, changes in applicable tax rates, transfer pricing rules or in the valuation of DEME's deferred tax assets and liabilities, DEME's ability to utilise tax losses and tax credits, changes to interest deductibility or other changes in the tax laws and the way such laws are applied by tax administrations (possibly retroactively). This also encompasses tax arrangements issued by the tax authorities and corresponding challenges by tax authorities to DEME's judgement or interpretation in tax matters.	As mentioned, taxation can be subject to judgements and might result in disputes with local tax authorities. If management considers it probable that such disputes will lead to an outflow of resources, accruals have been recorded accordingly. Although DEME believes its tax estimates are reasonable, due to continuous screening by its Tax Department, any final determination could be different from the treatment reflected in DEME's historical income tax provisions and accruals.
Litigations
DEME has been and may continue to be involved in litigation, other legal claims and proceedings, investigations and regulatory enforcement actions from time to time with various parties in the course of its business. Disputes may, for instance, arise around different interpretations of new items emerging during the performance of the contract, or around misinterpretations of contractual clauses. DEME's business is also subject to operational risks, including environmental hazards, accidents, disruption or flooding, which could result in damage or even the destruction of equipment, structures or buildings, environmental damage, personal injuries or legal liability towards third parties.	Disputes and legal proceedings are subject to many uncertainties, and their outcomes are often difficult to predict. Some of these proceedings can lead to paying damages, remedies or criminal/civil sanctions, fines or disgorgement of profit. The defence of any such claims and any associated settlement costs can be substantial, even with respect to claims that have no merit.	As a general rule, DEME's contracts are subject to the laws of the countries in which the projects are executed, supplemented where possible by the arbitration clause of the International Chamber of Commerce, in particular for countries where the legal system might not offer sufficient protection.

The company may even be involved in proceedings initiated by employees or former employees with occupational disease claims related to certain activities (e.g. diving, working in the sun for extensive periods) or to exposure to hazardous substances (e.g. fumes, corrosive or toxic substances), among other things.

	Information technology is crucial in supporting and protecting core and supporting processes. This enables DEME to work more fluidly and
	efficiently and makes it possible to follow up its local operations in almost real-time
	from its headquarters, but it also leads to a vulnerability linked to cyber security challenges and dependency on digitalised processes.

Internal policies, procedures and instructions are in place to mitigate the information technology risk. These include Multi-factor Authentication, single sign-on with Office 365 for all cloud-based applications, hard-disk encryption, as well as End-Point protection on all PCs, regular "Ethical hacking" exercises, awareness campaigns and penetration testing by the Enterprise Security Office (ESO).

In its role, ESO provides the management with periodic updates on the security risk landscape and performs security risk assessments. As such, the ESO informs the Group about potential threats to the security of staff and property.

Cyber security

Cyber security is a vital aspect of our business as we operate in a highly competitive and dynamic market that requires constant innovation, adaptation and vigilance.

We are committed to protecting our people, data, assets, and customers from cyber threats, and to comply with the relevant regulations and standards.

We are aware of the challenges and opportunities that lie ahead. The cyber threat landscape is constantly evolving and becoming more sophisticated and complex, as cyber criminals and adversaries exploit modern technologies and vulnerabilities. We also face increasing regulatory and customer expectations and demands, as well as competitive and market pressure.

One of the main goals of DEME's Cyber Security Strategy is to establish a robust and consistent framework that guides our policies, procedures, and practices. To this end, it has adopted the Centre for Internet Security (CIS) Controls, a set of best practices that are aligned with the most widely recognised cyber security standards, such as NIST (National Institute of Standards & Technology) and MITRE ATT&CK® (a globally-accessible knowledge base of adversary tactics and techniques based on real-world observations). The CIS Controls, which have been implemented throughout the organisation, provide a comprehensive and actionable roadmap to improve cyber security and to measure progress and performance. In addition, DEME has undertaken several specific initiatives and projects to enhance its cyber security capabilities and resilience:

• — Full rollout of Multi-factor Authentication (MFA) for all employees, contractors, and partners. MFA reduces the risk of unauthorised access and data breaches. — Establishing a 24/7 Cyber Security
• Centre (SOC), a dedicated team of experts and analysts that monitor, detect, and respond to cyber incidents and threats.
• — Improvements in Disaster Recovery: increasing our Data Centre redundancy and backup capabilities. DEME has invested in multiple data centres located in different zones, and improved its backup and recovery processes by using cloud-based solutions.
• — Deployment of Starlink, a satellite-based internet service that provides high-speed and low-latency connectivity to its fleet. Starlink, in combination with next-generation firewalls, enhances cyber security by enabling DEME to encrypt and secure its data transmissions.
• — Conducting ethical hacker testing to identify and address potential vulnerabilities.
• — Investing in training to equip the workforce so they can identify and counteract potential cyber security risks

IT Risks

Other risks

Description of the risk	Potential impact	Risk management and control
Employment
DEME heavily relies on qualified, highly skilled personnel, professionals and managers.	The success of DEME's business depends largely on its ability to continue to recruit and retain skilled personnel, and to do so at competitive conditions. DEME must recruit and retain adequate numbers of highly qualified engineers, professionals and managers. Not being able to attract talent could limit the execution of current operations, as well as have an impact on the growth of DEME.	To attract talent in this highly competitive market, DEME has a professional recruitment team. It is vital to motivate and retain its valuable employees, therefore DEME tries to recompense the long working hours, shift work, and night-time and weekend work with attractive conditions of employment and holiday arrangements. The company also invests in the development of employees through various training programmes and prepares candidates for key promotions to improve their leadership capabilities.
Intellectual property
DEME makes use of certain proprietary technology and knowhow, including intellectual property and innovations that it has developed itself.	To obtain a competitive advantage, DEME must use state-of-the-art technologies, often developed by its own employees.	DEME enters into confidentiality agreements with third parties that are involved in Research & Development. The intellectual property rights arising from this R&D are owned by DEME on the basis of a standard contract with the inventor. Depending on the type and value of the intellectual property it may be protected further by filing a patent application.
Outbreak of pandemic disease
A pandemic, such as covid-19, can negatively affect DEME's operations. It impacts the health of all our employees, suppliers, subcontractors and can disrupt the delivery of crucial supplies and lower demand.	An outbreak of a pandemic impacts the health of the crew and staff and business continuity, on board, at project sites and offices and consequently, it has an impact on the financial position of the company. Local or international measures can limit travelling and include possible quarantine measures.	Cooperation from all staff and crew, and compliance with DEME's health and safety measures and vaccination recommendations enabled the company to limit the number of covid infections. During 2023, DEME has kept the mitigation measures and protocols largely in place to assess the covid evolution and the associated government measures. The evolution and risks now appear to be reasonably under control with

most governments relaxing their regulations.
