Chairman’s Statement

On behalf of the Board, I am pleased to report on the performance and activities of the Company in 2024.

Simon Hogan
Chairman

Hydrogen Industry Landscape

The transition to a low carbon economy presents a significant opportunity for HydrogenOne Capital Growth plc. It is timely that we are investing in hydrogen and that our investments are aligned with this global transition. Whilst I do not consider this year to have been a particularly good period, it has been a time of considerable change and transition within the hydrogen sector.

Primarily, we have seen increased and sustained government policy responses upon demand in hydrogen. This year has been one of our most active investment periods to date. The scale of this investment and our future deployment of capital is unprecedented. We believe that this year presents a unique opportunity for us to invest in the hydrogen companies of tomorrow.

I believe that HydrogenOne’s purpose remains the same: to generate attractive risk-adjusted returns for shareholders by investing in a diversified portfolio of hydrogen companies. The Group is uniquely positioned to identify, invest in and grow the next generation of hydrogen businesses.

Indeed, this year has seen a flurry of activity across the hydrogen ecosystem. The number of companies seeking funding has, and continues to, outstrip supply. It is of course, the Group’s duty to ensure that we continue to identify the best opportunities for our investors.

In terms of market valuation, we have seen considerable volatility in our portfolio. Despite this, I believe that our portfolio remains at a discount to NAV.

In 2024, we have also seen considerable progress in our investment portfolio. We have continued to deploy capital into the most promising hydrogen businesses, across the value chain and into new and emerging technologies. We are confident that these investments will deliver attractive returns for our shareholders over the medium to long term.

Share Price Discount

Whilst this period has seen us evaluate and invest into a range of new opportunities within the hydrogen sector, we have also seen our share price trade at a discount to NAV. Our assessment that our portfolio is trading at a significant discount to NAV of £6.00 to £6.10, compared to an estimated NAV of £6.10 to £6.11.

This discount has, in part, been driven by our significant period of investment in the Group. Indeed, we have continued to deploy capital into new and existing portfolio companies, with a view to generating significant future returns. We believe that this period of investment, whilst potentially impacting our short term NAV, will be crucial in generating long term value for our shareholders.

In terms of market valuation, we believe that our portfolio is trading at a significant discount to NAV of £6.10 to £6.11.

We believe that the Company's NAV reflects the value of our underlying investments which we continue to believe are trading at a significant discount to NAV. Our NAV has been impacted by our significant deployment into new and existing portfolio companies. The Board believes that this strategy, whilst potentially impacting our short term NAV, will be crucial in generating long term value for our shareholders.

We are confident that the Group’s investment strategy remains appropriate for the market in which it operates. The Board believes that our strategy of investing in the hydrogen sector is well-placed to deliver significant returns for our shareholders.

Outlook for 2025

The Group anticipates further growth in 2025, with a focus on enhancing our existing portfolio's performance. Our strategy of deploying capital into new and existing hydrogen businesses has been successful. Our strategy has delivered decisions that have been instrumental in uplifting our portfolio. However, in 2025, the Board believes that it is important to focus on value realisation, with a view to enhancing shareholder returns.

The Group is also a strong advocate for our shareholders. Our shareholders have, and continue to, see significant value in our strategy. Our strategy of investing in the hydrogen sector is well-placed to deliver significant returns for our shareholders.

Investment Strategy and Update

The Group’s investment strategy is to make a diversified investment across hydrogen-related businesses, and that this will be of considerable importance in delivering attractive risk adjusted returns. We will seek to identify, invest in and grow the next generation of hydrogen businesses.

We continue to believe that our strategy is well-aligned with the market. The scale of our current investment in hydrogen is significant. We are focused on identifying companies with strong management teams, significant market opportunities and the potential to deliver substantial returns.

Indeed, the market for hydrogen is significant. We see considerable opportunities in the supply chain, storage, hydrogen applications and in developing new technologies.

Investment Pipeline

The Group continues to see a strong pipeline of investment opportunities. We have a number of active discussions ongoing. We are also looking to identify a number of new companies within the sector for investment over the next 12 months.

Valuation

The Group has undertaken a valuation exercise based on the portfolio, derived from investing in companies that are primarily focused on hydrogen. This has been completed using the methodology of the Company’s independent investment manager. We have independently valued the portfolio at £250 million, derived from the acquisition of £215 million of our own holdings and £35 million in independently managed funds. This has been driven from £245 million in holdings and £5 million in net investments.

The Group’s investment portfolio continues to see significant investment in and development of companies. We have also seen our portfolio company, ITM Power, see significant share price growth. This has been driven from £60 million to £230 million in value in the last 12 months.

Environment, Social & Governance

ESG is integral to our investment strategy. The Company is committed to responsible investment in all its portfolio companies. We believe that this commitment to ESG principles is fundamental to our investment strategy. Indeed, this year has seen us invest in significant new ESG commitments.

The ESG commitments for our investments are driven by the principles of the UN SDGs. We believe that these drivers are fundamental to our investment strategy. We are also undertaking a range of activities in line with the TCFD. We believe that our TCFD strategy will be fundamental to our ESG reporting.# HydrogenOne Capital Growth plc Annual Report 2024

About Clean Hydrogen

  • Clean hydrogen displaces fossil fuels, reducing CO2 emissions and improving air quality
  • Some 97 million tonnes per annum (“mtpa”) of hydrogen is used today in manufacturing of oil products, chemicals and steel. The demand to replace this polluting ‘grey’ hydrogen with clean hydrogen underpins the clean hydrogen sector
  • By 2027, some 3.0 mpta of green hydrogen is expected to be in production, following investment of some £50billion, representing c. 15x of the current hydrogen market, and predominately used to replace grey hydrogen
  • Clean hydrogen can replace fossil fuels in hard to decarbonise sectors such as power generation and transport
  • Clean hydrogen is a key component in the manufacture of clean e-fuels, such as e-methanol and synthetic aviation fuel (“e-SAF”);
  • Clean hydrogen is an energy carrier, that can store and distribute intermittent renewable electricity at a large scale
  • Hydrogen, when combined with renewables such as wind and solar provides, a domestic energy supply option for many countries, reducing reliance on imported energy and improving energy security.

Investment objective

The Company’s investment objective is to deliver an attractive level of capital growth by investing, directly or indirectly, in a diversified portfolio of hydrogen and complementary hydrogen focussed assets whilst integrating core ESG principles into its decision making and ownership process.

Investment policy

The Company will seek to achieve its investment objective through investment in a diversified portfolio of hydrogen and complementary hydrogen focussed assets, with an expected focus in developed markets in Europe, NorthAmerica, the GCC and Asia Pacific, comprising:

i. assets that produce clean hydrogen;
ii. large scale energy storage assets;
iii. carbon capture, use and storage assets;
iv. hydrogen distribution infrastructure assets;
v. assets involved in hydrogen supply chains, such as electrolysers and fuel cells; and
vi. businesses that utilise hydrogen applications such as transport, power generation, feedstock and heat (together “Hydrogen Assets”).

The Company intends to implement its investment policy through the acquisition of hydrogen and complementary hydrogen focussed assets.

Private Hydrogen Assets

The Company invests in unquoted Hydrogen Assets, which may be operational companies or hydrogen projects (completed or under construction) (“Private Hydrogen Assets”). Investments are expected to be mainly in the form of equity, although investments may be made by way of debt and/or convertible securities.

The Company may acquire a mix of controlling and non-controlling interests in Private Hydrogen Assets, however the Company intends to invest principally in non-controlling positions (with suitable minority protection rights to, inter alia, ensure that the Private Hydrogen Assets are operated and managed in a manner that is consistent with the Company’s investment policy).

Given the time frame required to fully maximise the value of an investment, the Company expects that investments in Private Hydrogen Assets will be held for the medium to long term, although short term disposals of assets cannot be ruled out in exceptional or opportunistic circumstances. The Company intends to re-invest the proceeds of disposals in accordance with the Company’s investment policy.

The Company observes the following investment restrictions, assessed at the time of an investment, when making investments in Private Hydrogen Assets:

  • no single Private Hydrogen Asset will account for more than 20 per cent. of Gross Asset Value;
  • Private Hydrogen Assets located outside developed markets in Europe, North America, the GCC and Asia Pacific will account for no more than 20 per cent. of Gross Asset Value; and
  • at the time of an investment, the aggregate value of the Company’s investments in Private Hydrogen Assets under contract to any single Offtaker will not exceed 40 per cent. of Gross Asset Value.

The Company will initially acquire Private Hydrogen Assets via HydrogenOne Capital Growth Investments 1 LP (the ‘HydrogenOne Partnership’), a wholly owned subsidiary undertaking of the Company structured as an English limited partnership which is controlled by the Company and advised by the Investment Adviser. The HydrogenOne Partnership’s investment policy and restrictions are the same as the Company’s investment policy and restrictions for Private Hydrogen Assets and cannot be changed without the Company’s consent.

In due course, the Company may acquire Private Hydrogen Assets directly or by way of holdings in special purpose vehicles or intermediate holding entities (including successor limited partnerships established on substantially the same terms as the HydrogenOne Partnership) or, if the Company is considered a ‘feeder fund’ under the Listing Rules, other undertakings advised by the Investment Adviser and, in such circumstances, the investment policy and restrictions will also be applied on a look-through basis and such undertaking(s) will also be managed in accordance with the Company’s investment policy.

Listed Hydrogen Assets

The Company also invests in quoted or traded Hydrogen Assets, which will predominantly be equity securities but may also be corporate debt and/or other financial instruments (“Listed Hydrogen Assets”). The Company is free to invest in Listed Hydrogen Assets in any market or country with a market capitalisation (at the time of investment) of at least US$100 million. The Company’s approach is to be a long-term investor and will not ordinarily adopt short-term trading strategies. As the allocation to Private Hydrogen Assets grows the Listed Hydrogen Assets are expected to include strategic equity holdings derived from the listing of operational companies within the Private Hydrogen Assets portfolio over time.

The Company observes the following investment restrictions, assessed at the time of an investment, when making investments in Listed Hydrogen Assets:

  • no single Listed Hydrogen Asset will account for more than 3 per cent. of the Gross Asset Value;
  • each Listed Hydrogen Asset must derive at least 50% of revenues from hydrogen and/or related technologies; and
  • the target allocation to Listed Hydrogen Assets will be approximately 10 per cent or less of Gross Asset Value, subject to a maximum allocation of 30 per cent of Gross Asset Value.

During the year ended 31 December 2024, the Company realised its remaining Listed Hydrogen Assets.

Cash

During the initial Private Hydrogen Asset investment period after a capital raise and/or a realisation of a Private Hydrogen Asset, the Company intends to hold the relevant net proceeds of such capital raise/realisation in cash (in accordance with the Company’s cash management policy set out below) pending subsequent investment in Private Hydrogen Assets.

Investment restrictions

The Company, in addition to the investment restrictions set out above, comply with the following investment restrictions when investing in Hydrogen Assets:

  • the Company will not conduct any trading activity which is significant in the context of the Company as a whole;
  • the Company will, at all times, invest and manage its assets
    • in a way which is consistent with its objective of spreading investment risk; and
    • in accordance with its published investment policy;
  • the Company will not invest in other UK listed closed-ended investment companies; and
  • no investments will be made in companies or projects that generate revenues from the extraction or production of fossil fuels (mining, drilling or other such extraction of thermal coal, oil or gas deposits).

Compliance with the above restrictions is measured at the time of investment and non-compliance resulting from changes in the price or value of Hydrogen Assets following investment will not be considered as a breach of the investment policy or restrictions.

Borrowing policy

The Company may take on debt for general working capital purposes or to finance investments and/or acquisitions, provided that at the time of drawing down (or acquiring) any debt (including limited recourse debt), total debt will not exceed 25 per cent of the prevailing Gross Asset Value at the time of drawing down (or acquiring) such debt.

For the avoidance of doubt, in calculating gearing, no account will be taken of any investments in Hydrogen Assets that are made by the Company by way of a debt investment.

Gearing may be employed at the level of a special purpose vehicle (“SPV”) or any intermediate subsidiary undertaking of the Company (such as the HydrogenOne Partnership) or, if the Company is considered a ‘feeder fund’ under the Listing Rules, other undertakings advised by the Investment Adviser in which the Company has invested or the Company itself.

The limits on debt shall apply on a consolidated and look-through basis across the Company, the SPV or any such intermediate holding entities (such as the HydrogenOne Partnership) or, if the Company is considered a ‘feeder fund’ under the Listing Rules, other undertakings advised by the Investment Adviser in which the Company has invested but intra-group debt will not be counted.

Gearing of one or more Hydrogen Assets in which the Company has a non-controlling interest will not count towards these borrowing restrictions. However, in such circumstances, the matter will be brought to the attention of the Board who will determine the appropriate course of action.

Currency and hedging policy

The Company has the ability to enter into hedging transactions for the purpose of efficient portfolio management. In particular, the Company may engage in currency, inflation, interest rates, energy prices and commodity prices hedging. Any such hedging transactions will not be undertaken for speculative purposes.

Cash management

The Company may hold cash on deposit and may invest in cash equivalent investments, which may include short-term investments in money market type funds (“Cash and Cash Equivalents”). There is no restriction on the amount of Cash and Cash Equivalents that the Company may hold and there may be times when it is appropriate for the Company to have a significant Cash and Cash Equivalents position. In particular, the Company anticipates holding cash to cover the near-term capital requirements of the Pipeline of Private Hydrogen Assets and in periods of high market volatility.

For the avoidance of doubt, the restrictions set out above in relation to investing in UK listed closed-ended investment companies do not apply to money market type funds.

Strategy, business model and KPIs

A highly differentiated strategy, 100% focussed on clean hydrogen

The Company offers distinctive access to private investments, across the full hydrogen value chain, and across the OECD. The investment objective is to deliver an attractive level of capital growth by investing, directly or indirectly, in a diversified portfolio of hydrogen and complementary hydrogen focussed assets whilst, as a SFDR Article 9, PRI and Green Economy Mark company, integrating core ESG principles into our decision making and ownership process, for a positive environmental impact. As the first UK listed investment company specialising in this sector, the Company has a clear competitive advantage as an early mover into a complex sector, and offers its investors a unique window into the private hydrogen asset market. With its emphasis on Private Hydrogen Assets, the Company, gives investors an opportunity to be exposed to liquidity and portfolio diversity in hydrogen companies and projects, hard to access elsewhere, with strong growth potential. An investment in the Company offers exposure to the broader hydrogen sector whilst, at the same time, diversifying risk for an investor. By targeting a diversified portfolio of listed and private investments across different jurisdictions and different technologies, the Company seeks to spread some of the key underlying risks relating to clean hydrogen. A focus on material ESG factors, and especially the deployment of capital to deliver the energy transition to a low carbon economy, is at the heart of what the Investment Adviser does, running hand in hand with a strategy to deliver the target 10-15% per annum NAV growth for the investors. The Investment Adviser is a specialist investor in this complex and rapidly-developing growth sector. The Company believes that this specialised approach is a competitive advantage that will only grow over time. By excluding companies or projects that generate revenues from the extraction or production of fossil fuels (mining, drilling or other such extraction of thermal coal, oil or gas deposits) from the portfolio and taking on further ESG screens, the portfolio is expected to be an early mover to Net Zero in the energy transition, and will not be encumbered by the legacy greenhouse gas emissions inherent in other players in the hydrogen sector. The clean hydrogen industry in the short term is dominated by bespoke sources of hydrogen supply, financed by specialised offtakers, typically at 5MW to 50MW scale. In the period from 2025 to 2030 the Investment Adviser expects these facilities to be upscaled to 100MW to 500MW scale, and ultimately to 1GW to 5GW. The Investment Adviser also believes that energy storage and CCS projects will also increase in scale in this timeframe, with the development of compressed air energy storage followed by hydrogen storage and long-distance transport through pipelines, as liquid hydrogen or as ammonia or e-methanol on ships.

Business model

The Company is an investment company and its purpose, strategy, investment objective and policy are set out in the Annual Report. Any material change to the investment policy requires shareholder approval. The Company makes its investment in Private Hydrogen Assets through HydrogenOne Capital Growth Investments (1) LP (the “HydrogenOne Partnership” or the “Limited Partnership”), in which the Company is the sole limited partner. The Company may also acquire Private Hydrogen Assets directly or by way of holdings in special purpose vehicles or intermediate holding entities. The General Partner of the Limited Partnership is HydrogenOne Capital Growth (GP) Limited (the “General Partner”), a wholly owned subsidiary of the Company. During the year, a new wholly owned subsidiary of the Company, HydrogenOne Capital Growth Investments (1A) LP, was incorporated. Further details of the Company and Group structure are given in note 1 to the Parent and Consolidated Financial Statements (the “Financial Statements”). Other than where specified, references to the Company in this document refer to the Company together with its wholly-owned subsidiaries and investment as sole limited partner in the Limited Partnership.# The Company is governed by a Board of Directors (the “Board”), all of whom are non-executive, and it has no employees. The business model adopted by the Board to achieve the Company’s objective has been to contract the services of FundRock Management Company (Guernsey) Limited as the Alternative Investment Fund Manager of the Company, pursuant to the AIFM Agreement (the “AIFM”). The AIFM has appointed HydrogenOne Capital LLP to provide investment advisory services in respect of the Company (the “Investment Adviser”). The Investment Adviser will advise on the portfolio in accordance with the Board’s strategy and under its and the AIFM’s oversight. The Principals of the Investment Adviser responsible for the day-to-day monitoring of the portfolio are Dr John Joseph “JJ” Traynor and Richard Hulf. The Board and the AIFM monitor adherence to the Company’s investment policy and regularly reviews the Company’s performance in meeting its investment objective. All administrative support is provided by third parties under the oversight of the Board. Company secretarial and administration services have been delegated to Apex Listed Companies Services (UK) Limited (“Apex” or the “Administrator”); custody services to Northern Trust Company (“Northern Trust”); registrar services to Computershare Investor Services plc (“Computershare”); and effective 12January 2023, the Company’s broker is Barclays Bank PLC (“Barclays” or the “Broker”). Prior to this date the Company’s broker was Panmure Gordon (UK) Limited. The Board reviews the performance of the AIFM, the Investment Adviser and other key service providers on an ongoing basis. Further details of the material contracts of the Company are given in note 14 to the Financial Statements.

18 Investment Adviser’s Report

Introduction

The Company’s Alternative Investment Fund Manager (“AIFM”), FundRock Management Company (Guernsey) Limited, (part of Apex Group), has appointed HydrogenOne Capital LLP as the Investment Adviser to the AIFM in respect of the Company. Its key responsibilities are to originate, analyse, assess and recommend suitable investments within the hydrogen sector, and advise the AIFM accordingly. Additionally, the Investment Adviser performs asset management services in relation to the investments in the portfolio or, to the extent asset management is delegated to third parties, oversees and monitors such asset management. HydrogenOne Capital LLP was founded in 2020 as an alternative investment firm focussed specifically on investing in hydrogen assets and their role in the energy transition. As a responsible investor, HydrogenOne Capital LLP is committed to contributing to the energy transition through the financing of sustainable investments and by providing investment solutions that reduce carbon emissions. HydrogenOne Capital LLP employs a fully integrated investment and asset management approach and integrates its focus on ESG criteria throughout the entire investment process.

The Principals of the Investment Adviser

The Principals of the Investment Adviser have in excess of 60 years of combined experience and a track record of success in the energy industry and capital markets which are directly applicable to the hydrogen industry, including acquisitions, mergers and divestments, development of growth energy projects, supervision of profitable energy production, ESG track record, investments in both listed and private companies and board advisory. Their biographies are included on page 46.

The Investment Adviser’s team

The Principals have assembled an experienced team to support the Company. This group brings a mixture of finance, technical and sector skills to support the Investment Adviser in its day-to-day activity. The Investment Adviser has established a team which is responsible for financial modelling, corporate and asset valuation analysis, and opportunity assessment for the Company.# HydrogenOne Capital Growth plc Annual Report 2024

19

The Principals anticipate a further increase in headcount should the Company grow its activities.

Advisory Board of the Investment Adviser

The Principals of the Investment Adviser are supported by an experienced team which comprises the Advisory Board. The Advisory Board has been carefully selected to provide expert advice to the Investment Adviser on the hydrogen sector, project finance and capital markets. The Investment Adviser has appointed the members of the Advisory Board to provide it with advice from time to time. No members of the Advisory Board are directors, officers, employees or consultants of the Company, the AIFM or the Investment Adviser. It is envisaged that the Advisory Board will evolve over time, with additional experts being added or substituted as and when required.

Hydrogen sector landscape

An interplay of government policies and energy pricing continue to underpin the growth rate in the clean hydrogen sector. Governments set frameworks and funding for delivery of energy transition to net zero, improved air quality and energy security. Industrial companies and financial markets seek to capitalise on these policies, in order to offer customers price competitive, safe and reliable energy and feedstocks.

Clean hydrogen has a key role today in decarbonisation of manufacturing process such as oil refining and chemicals. Over time, clean hydrogen will also have a role in heating, the transport sector and natural gas grid blending. Clean hydrogen is also emerging as a key component in the manufacture of synthetic fuels such e-methanol, synthetic aviation fuel (“e-SAF”), and green ammonia.

Despite this key present and future role for the clean hydrogen sector, recent months have been marked by a series of project delays and cancellations in the clean hydrogen sector. Albeit such announcements are typically from higher cost and longer-term clean hydrogen opportunities. Equally, the new US Government, which was elected in 2024, has rolled back on prior policies to stimulate low carbon energy, instead placing renewed emphasis on fossil fuels.

Looking ahead to 2025, there is the prospect of lower oil & gas prices, should Russia return to the international market, which could undermine the case for higher cost renewables. However, the attractiveness of renewables for energy security in regions such as the EU, which are importers of fossil fuels, will be supportive. Many of these factors are short term in nature, but are not helpful for market sentiment for the sector or the Company.

The structural, long-term fundamentals of the sector, remain positive, despite these near-term effects. Evidencing this, landmark project announcements in 2024 include medium term proposals in Rajasthan, India, where Avaada Group is intending to commit $12 billion to a Global Renewable Energy Hub, and a TotalEnergies-led hydrogen and ammonia project in Morocco, costing some $11 billion, and a number of other projects primarily across Africa, Spain and China. By our estimates, there has been £9 billion of private sector investment in clean hydrogen in 2024 alone, which is a 50% increase over 2023 levels. Policy support announcements around the world exceeded $100 billion in 2024, albeit much of this has yet to be deployed. Some 200,000 tonnes per year of green hydrogen production (1.5 GW) was online globally at the end of 2024, a 25% increase year-on-year. This includes the start-up of the 110MW Shenghong Petrochemical Green Project, in China and a new 40MW hydrogen plant in Camden County, Georgia, USA. Adding to this, a further 2.8 million tonnes perannum of green hydrogen production (21.5 GW) has passed Final Investment Decision, representing a 15 fold increase in supplies, and a total investment of $69 billion. This represents an approximately threefold increase on the outlook compared to end-2023. In addition, there are some 46.8 mtpa (358GW) of further projects in development world-wide, an increase of over 300GW from 2023, which could result in over 44 mtpa of hydrogen supply and 4.4mpta avoided greenhouse gas emissions. All of this underscores the positive industry outlook and supportive regulatory regimes for clean hydrogen. This growth outlook for clean hydrogen demand underpins the order books in many of the Company’s investments, particularly in supply chain sectors such as electrolysers, fuel cells, storage and transportation businesses. Many of these businesses have world-wide customer bases for their products, and are attracting investment from international financial and strategic investors.

Valuation

As set out in note 4 of the Financial Statements, the Investment Adviser has carried out fair market valuations of the Private Hydrogen Assets at 31 December 2024, which have been reviewed by the Valuation Committee, and the Directors have satisfied themselves as to the methodology used, the discount rates and key assumptions applied. Private Hydrogen Assets at 31 December 2024 have been valued using either the discounted cash flow (‘DCF’) methodology or net asset values consistent with the International Private Equity and Venture Capital Valuation (“IPEV”) Guidelines. The valuations are also benchmarked against listed peer group valuations. Listed Hydrogen Assets are valued at fair value, which is the bid market price, or, if bid price is unavailable, last traded price on the relevant exchange. At 31 December 2024, the Company had no Listed Hydrogen Assets. Our approach to valuation remains consistent and unchanged. Valuations are updated for all Private Hydrogen Assets on a quarterly basis and approved by the AIFM, the Valuation Committee and the Board, and are audited annually by the Company’s auditor, KPMG.

Company performance valuation movements reflect internal factors including actual and budgeted/forecast financial performance. Macroeconomic valuation movements reflect external factors including inflation, discount rates and FX rates.

Discount rates are calculated using market parameters for each investment domicile. The weighted average discount rate for 31 December 2024 was 12.8% compared with 14.2% at 31 December 2023. The Company notes that its NAV reflects portfolio company performance and our consistent valuation methodology, driven by organic growth in the Company’s private assets, with some offsets from headwinds in the pace of market development, and write downs in 2024. By contrast, the share prices of listed hydrogen companies, which we track with the SOLGHYD index, have been highly volatile and declining since Q3 2021. Listed hydrogen shares are trading on market expectations rather than bottom-up fundamentals. This share price decline is in a large part due to market allocation away from early-stage technology businesses as interest rates have risen, and a correction to the high valuations seen in the market in 2020-21. The Company’s own share price has tracked this decline in listed hydrogen companies, and listed funds in general. In 2021-22, the Company assessed that many listed hydrogen companies were trading on higher valuations than its private portfolio companies, based on forward multiples of revenues. At the end of 2023, the revenue multiples of the listed hydrogen sector and the Company’s private portfolio had converged, as the listed hydrogen sector had de-rated. The Company has identified a basket of listed comparable hydrogen companies for each private portfolio company, and keeps track of their financials using Bloomberg. At the end of 2024, the forward exit revenue multiples of our comparable list of hydrogen companies are trading higher than their respective private portfolio companies. The average revenue exit multiple of the private portfolio companies is 2.1x (based on the Company’s valuation models), whereas the average revenue multiple of the listed comparable hydrogen companies is 3.8x (sourced from Bloomberg).

2024 Performance and 2025 outlook

The Company’s NAV decreased by 12.2% from £132.7 million at 31 December 2023 to £116.4 million at 31 December 2024. NAV per share decreased to 90.39p at 31 December 2024. The NAV reduced by 12.6p from 31 December 2023 to 31 December 2024, including the write-down of HH2E (6.9p), exchange rate impacts, fund costs and other portfolio impacts. The Company followed a strategy to exit from green hydrogen developer businesses Gen2 Energy and HH2E and the Thierbach SPV in 2024. The Company invested in the Series A in both of these businesses, which used these funds to prepare large scale green hydrogen projects for Final Investment Decision (“FID”). During 2024, the Company swapped its investment in HH2E’s Thierbach SPV for additional equity in HH2E. As Gen2 Energy and HH2E delineated FIDs costing in excess of £100 million, the Company assessed that it would not be in a position to invest at that scale, and hence sought to exit from these businesses at or around the FIDs, in order to crystallise value for shareholders, and provide further cash for the Company. Gen2 Energy was sold as planned for c. £3 million in November 2024, which reflected the unaudited carrying value at 30 June 2024. However, HH2E’s major shareholder’s decision to cease funding for HH2E in November 2024 resulted in the business entering self-administration, halting the Company’s plans for a divestment, and leading to an 8.4 pence per share write off of the Company’s NAV. HH2E had over-invested in long-lead equipment ahead of its first FID, with some £59m of shareholder loans committed. HH2E was unable to deliver the hydrogen gas offtake agreements that new investors had sought in its Series B funding round. The major shareholder declined to provide further funding to bridge HH2E to its Series B, resulting in HH2E entering self-administration. The Company has assessed that HH2E’s write off was due to company-specific issues and should not impact the outlook for the remainder of its portfolio. Electrolyser companies Sunfire and HiiROC saw increases in valuation in 2024, boosting the Company’s NAV, underpinned by fresh investment, order books and financial performance. By contrast, the valuations of low carbon pipeline manufacturer Strohm, and solid oxide fuel cell maker Elcogen were reduced as a result of delays to order books and timing issues on manufacturing capacity ramp ups. Strohm has adapted its strategy to reflect the slower pace in roll out of offshore hydrogen, by focusing on traditional offshore energy and CCS opportunities. Elcogen’s strategy was adjusted in 2024 to focus on strong near term growth in stationary power markets, using fuel cell, with reduced near-term emphasis on sold oxide electrolysis offerings. The development of the hydrogen transport sector has slowed, particularly in the United Kingdom, as a result of the push back of Government targets for low carbon transport. As a result, hydrogen transport and distribution company NanoSUN has been restructured, taken out of administration into sole ownership by the Company during 2024, rebranded as Swift Hydrogen, and held as an intellectual property holding company.# HydrogenOne Capital Growth plc Annual Report 2024

HiiROC continued to deploy its thermal plasma electrolysis technology at two industrial sites in the UK, with Cemex and Centrica. Cranfield Aerospace continued to develop its hydrogen electric flight technology, and Bramble progressed innovation in printed circuit board fuel cells.

Portfolio companies generally require fresh funding in order to sustain their business models. In 2024, portfolio companies in total accessed over £500 million of funding from equity, debt and grants. Despite this, both NanoSUN and HH2E failed to access sufficient capital to continue as going concerns in 2024, due to market conditions, and there can be no certainty that sufficient funding will be available in the future, raising the risk of dilution of the Company’s holdings.

The Company exited its listed hydrogen holdings during 2024, as part of a strategy to focus on cash management. Portfolio companies delivered an aggregate £85 million in total revenue in the year to 31 December 2024, an increase of 14.9% compared to the year to 31 December 2023. This growth was driven by order books in key technologies such as electrolysers, fuel cells and low carbon pipelines.

The Company’s investment activity centred on follow-ons in existing companies during 2024. During the year ended 31 December 2024, the Company made £2.6 million investments in Sunfire, Strohm, Cranfield and Swift, including investments made as convertible loans, to limit the impact of equity dilution from future funding rounds. Portfolio companies have raised a total of c. £500 million in 2024, comprising c. £220 million in new equity, secured c.£180 million in grant funding and c. £100 million in debt and bank guarantees, underpinning the Company’s valuations and the positive sector fundamentals.

Listed Hydrogen Assets

The Company fully realised the listed portfolio during 2024.

Analysis of financial results

The Financial Statements of the Company for the year ended 31 December 2024 are set out on pages 70 to 98.

Net assets
Net assets decreased from £132.7 million at 31 December 2023 to £116.4 million at 31 December 2024. The decrease in net assets was driven largely by the write down of the investment in HH2E. The net assets of £116.4 million comprise £113.7 million portfolio value of investments, including the holding in the HydrogenOne Partnership, and the Company’s cash balances of £2.8 million, and other net liabilities of £0.1 million. The Limited Partnership’s net assets of £113.7 million comprise £113.5 million portfolio value of investments (including accrued interest), cash balances of £0.3 million and liabilities of £56,000.

Cash
At 31 December 2024, the Company and the HydrogenOne Partnership (together the ’Group’) had a total cash balance of £3.1 million (2023: £4.7 million), including £0.3 million in the Limited Partnership, which is included in the Company’s balance sheet within ‘investments held at fair value through profit or loss’.

Loss for year
The Company’s total loss before tax for the year ended 31 December 2024 is £16.2 million (31 December 2023: profit of £7.3 million), generating a loss per Ordinary Share of 12.60 pence (31 December 2023: return of 5.68 pence per share). In the year to 31 December 2024, the losses on fair value of investments were £15.1 million (31 December 2023: gains of £9.1 million). The expenses included in the income statement for the year were £1.3 million, in line with expectations. These comprise £34,000 Investment Adviser fees and £1.2 million operating expenses. The details on how the Investment Adviser fees are charged are as set out in note 6 to the Financial Statements.

Ongoing charges
The ongoing charges ratio is an indicator of the costs incurred in the day-to-day management of the Company. The ongoing charges percentage for the year to 31 December 2024 was 2.53% (31 December 2023: 2.56%). The ongoing charges have been calculated, in accordance with AIC guidance, as annualised ongoing charges (i.e. excluding acquisition costs and other non-recurring items) divided by the average published undiluted Net Asset Value in the period. The calculation is provided on page 100. The ongoing charges percentage has been calculated on the amalgamated basis and therefore takes into consideration the expenses of HydrogenOne Partnership as well as the Company.

---# Principles of Responsible Investment

During the year the Company submitted its reporting to the Principles of Responsible Investment. The charts below show the scoring vs the peer group of investment managers in the same jurisdiction with similar assets under management. The results are favourable to the Company with performance above the median average in all three categories and particularly strong results in governance. Further work to enhance responsible investment performance will be undertaken in the current year.

No specific energy efficiency actions have been taken by the Company during the year.

  1. Notwithstanding any mitigation action in the respective supply chains, we expect that scope 3 emissions will increase as data gaps are closed and use of estimates are reduced as more reliable data from Private Hydrogen Assets becomes available.
  2. This metric reflects the electricity, energy, and fuel consumption (including transportation) of Private Hydrogen Assets located within the UK, presented proportionate to the Company’s equity share.
  3. This metric captures the electricity, energy, and fuel consumption (including transportation) of Private Hydrogen Assets located outside the UK, presented proportionate to the Company’s equity share.
  4. Carbon footprint and GHG intensity are distinct metrics that measure environmental impact. Carbon footprint represents the total emissions of investee companies divided by the current value of all investments, essentially showing emissions per value invested. GHG intensity measures emissions in relation to company revenues, indicating how emissions relate to economic output.

Principal risks and uncertainties

The Board, through delegation to the Audit and Risk Committee, has carried out a robust assessment of the emerging and principal risks facing the Company. These include those that would threaten its business model, future performance, solvency and liquidity (see Audit and Risk Committee Report in the Annual Report). The Audit and Risk Committee reviews ongoing monitoring of both risks and controls. This ensures heightened and emerging risks are identified outside of the normal cycle of Board and Audit and Risk Committee meetings. The Audit and Risk Committee undertook a comprehensive review of the Company’s risk management framework and controls during the year. The risks are documented on a risk register and each risk is rated by impact and probability with the assessed risk given a risk score and a residual rating. The risk register is reviewed on an ongoing basis in an attempt to capture all risks and put appropriate mitigation in place. The review takes into account changing factors including, but not restricted to, changes to markets (both macro and micro), stakeholders, operations, regulation and emerging risks. The top risks identified by this process are set out in the table below together with the mitigated approach, and the Board considers these to be the principal risks of the Company.

Increasing Stable Reducing Principal Risks and Uncertainties Mitigation
X Regulatory Changes in political or environmental conditions in the hydrogen sector (for example, changes in government policy or support) could affect the Company’s prospects. In addition, greater regulation in the financial services industry could materially affect the Company’s business. The Board and Investment Adviser has significant experience in the energy sector and is familiar with its volatile political and regulatory environment. Extensive contacts across the sector inform its ongoing monitoring of these risks, which are reported to the Board at least quarterly. More specific due diligence occurs prior to any investments and during the lifetime of their ownership. The Administrator has a strong track record in administering listed companies and the various rules and regulation required to be adhered to.
X Policy support The technologies required to produce and use green hydrogen need policy support to underpin the scale needed to drive stand-alone cost competitiveness. Governments worldwide are showing such support today, but that may be volatile over the investment time horizon of the Company. As noted under ‘regulatory’, the Investment Adviser has longstanding experience in the energy sector and monitors the policy environment closely. Such experience and awareness is also present among the Company’s Non-Executive Directors. The Company’s portfolio consists of a range of hydrogen projects in different countries and at different points in the emerging value chain, to further mitigate the risk of policy volatility.
X Operational Initial pre-deal due diligence may not uncover all risks associated to a transaction. Investments are subject to operating and technical risks. While the Company will seek investments with creditworthy and appropriately insured counterparties who bear the majority of these risks, there can be no assurance that all risks can be mitigated. In addition, the long-term profitability of hydrogen investments will be partly dependent upon the efficient operation and maintenance of the assets. Inefficiency, or limitations in the skills, experience or resources of operating companies, may reduce revenue. As a result, profitability of the Company may be impaired leading to reduced returns for Shareholders. The Investment Adviser conducts a vigorous due diligence process and works very closely with external and technically skilled consultancy firms to review all potential transactions, with an aim to provide a fully scoped and informed recommendation. The portfolio is constantly monitored by the Investment Adviser and the AIFM to address risks as they are identified. Diversification in counterparties and service providers ensures any impact is limited. Furthermore, the Company invests in a diversified portfolio.
X Performance Underperforming investment or investment strategy can lead to underperformance to the Company’s target return and ultimate investment objective. Risk assessment has increased from macroeconomic impacts on portfolio investments. The Board reviews at least quarterly the portfolio performance as well as underlying key asset risks identified as part of the Company’s risk register and how those risks are actively being mitigated which include but is not limited to: • Non Controlling interest risk • Market risk • Interest rate risk • Inflation risk At each Board meeting a report on risks, portfolio performance and any macro and micro considerations is provided by the Investment Adviser and the AIFM, and reviewed accordingly with the aim to mitigate such risks. In addition, the Investment Adviser has representation on each investee board either through a director or board observer position.

Principal Risks and Uncertainties

Mitigation
Future acquisitions and capital raises Ongoing capital raises are intended. The Company’s share price trading at an excessive discount to its net asset value may mean it is difficult to raise further capital through share issues for onward investment. Risk assessment has increased due to an increase in the share price discount compared to the net asset value of the Company during the year. The Company’s Broker monitors the market for the Company’s shares and reports at quarterly meetings. The Board regularly reviews the relative level of discount against the sector and has the authority to buy back shares.

Given what the Company understands to be a low risk profile of anyone supplying it with services being involved in slavery and/or human trafficking, it believes its current procedures and ability to rely on regulatory oversight in relation to professional services are sufficient in this regard.

Social, community and human rights issues

The Investment Adviser screens the Company’s Investable Universe as part of the Environmental Social and Governance analysis for any breaches of the principles of the UN Global Compact, including human rights, labour rights, environmental breaches and corruption. Any non-compliant companies are excluded from investment.

Anti-bribery and corruption

In accordance with the UK Bribery Act 2010, the Company has developed appropriate anti-bribery policies and procedures. The Company has a zero-tolerance policy towards bribery and is committed to carrying out its business fairly, honestly and openly. The anti-bribery policies and procedures apply to all its officers and to those who represent the Company (including its business partners). The Company expects those providing services to it, or on its behalf, to undertake their business without bribery.

Prevention of the facilitation of tax evasion

The Criminal Finances Act (Commencement No. 1) Regulations 2017 (SI 2017/739) brought Part 3 of the Criminal Finances Act 2017, the corporate offences of failure to prevent facilitation of tax evasion, into force on 30 September 2017. The Company does not tolerate tax evasion in any of its forms in its business. The Company complies with the relevant UK law and regulation in relation to the prevention of facilitation of tax evasion and supports efforts to eliminate the facilitation of tax evasion worldwide, and works to make sure its business partners share this commitment.

Asset allocation at year end

The breakdown of the structure of the portfolio at the Company’s year-end is shown on pages 96 to 98.

Dividends and dividend policy

The Ordinary Shares carry a right to receive dividends. If a dividend is to be declared, interim dividends are determined by the Board and a final dividend is subject to shareholder approval at the AGM.

Dividend policy

The Company is targeting a Net Asset Value total return of 10 to 15% per annum over the medium to long-term with further upside potential. The Company intends to invest in Hydrogen Assets with cash flow typically re-invested for further accretive growth. The Company only intends to pay dividends in order to satisfy the ongoing requirements under the Investment Trust (Approved Company) (Tax) Regulations 2011 for it to be approved by HMRC as an investment trust save that, in the medium term, the Company’s Hydrogen Assets may also generate free cash flow which the Company may decide not to re-invest and, in such case(s), the Company currently intends to distribute these amounts to Shareholders.

The Company’s revenue return after tax for the year amounted to a loss of £1,130,000 (31 December 2023: loss of £1,328,000). The Company made a capital loss after tax of £15,101,000 (2023: gain of 8,645,000). Therefore the total return after tax for the Company was a loss of £16,231,000 (2023: profit of £7,317,000). No dividends have been paid or are proposed for the year to 31 December 2024 (2023: nil).

Other informationThe Board and AIFM oversee the investment pipeline and monitor its progress in relation to Company targets. Certain assets will be identified in advance by the Investment Adviser as being potentially available for acquisition by the Company. The pipeline is managed by the Investment Adviser and monitored by the AIFM, with onward reporting to the Board. The Board is unlikely to agree to capital raises without a strong pipeline.

Liquidity and Refinancing

The operational risks of the Company including market, counterparty, credit and liquidity risk. Extreme market volatility can disrupt the capital raising process and ability to raise monies to repay a debt demand in full. Investments in Private Hydrogen Assets are illiquid in nature and may take a longer period of time to realise in order to fund the Company’s operations or meet its expenses. The Company has and may continue to be forced to sell liquid assets to meet its expenses at a time when valuations are lower for some assets. Should the Company no longer have sufficient liquid assets available to meet a projected 12 months’ worth of expenditure, the going concern status of the company may be called into question (see further details in Note 2 Basis of preparation in the Financial Statements). This risk has increased due to market volatility and the Company’s share price trading at a significant discount to net asset value, delaying the Company’s ability to raise capital. Higher interest rates will increase the cost of finance to the Company. The Investment Adviser closely monitors the liquidity in the market and portfolio valuations. Should new credit not be forthcoming, liquidity may be gained through a capital raise, or liquidation of assets. The Investment Adviser, AIFM and the Board continuously monitor forecast and actual cashflows from operating, financing, and investing activities to consider payment of dividends, or further investing activities.

Service providers

Disruption to, or failure of the Company’s Administrator or other parties to complete their role efficiently, on time and in line with expectation. All counterparties to the Company are reviewed as part of the risk register. A material credit risk is that of banks holding un- invested cash, the credit rating and credit worthiness of these are considered. A review of key operational counterparties, such as the Administrator, looking at operational procedures, disaster recovery and system security is undertaken. Counterparties of Company’s Special Purpose Vehicles (“SPV”) and underlying assets are carried out as part of the investment due diligence process.

Portfolio valuation

Risk that portfolio asset valuations published do not represent the Fair Market Values in accordance with the accounting requirements. Investment valuations are based on modelling / financial projections for the relevant investments and utilises International Private Equity and Venture Capital Valuation (“IPEV”) methodologies to calculate fair value. Projections will primarily be based on the Investment Adviser’s assessment and are only estimates of future results based on assumptions made at the time of the projection. Actual results may vary significantly from the projections, which may reduce the profitability of the Company leading to reduced returns to Shareholders. A rise in interest rates will lead to an increase in the Discount Rate applied to the Private Hydrogen Assets’ valuation, leading to a reduction in the Company’s net asset value. The Investment Adviser has significant experience in valuation of these assets. The discount rate used in the valuations incorporates spot gilt rates for each free cashflow based on maturity and country which mitigates the longer term impact of rises in interest rates. The valuation policies and valuations will be reviewed by the Valuation Committee on a quarterly basis, together with signing off on the Private Hydrogen Asset values.

Principal Risks and Uncertainties

Mitigation

Key person

The Investment Adviser is a small Company with minimum employees. As such, there are significant Key Person risks and should they become unavailable, this could have a negative impact on the Company’s ability to achieve its investment objective. The Investment Adviser is committed to expand its business/ staffing levels in order to diversify knowledge across the expanding team. This risk is covered in the risk register and reported on at each Board meeting.

Tax

Breaches of Section 1158 of the Corporation Tax Act could result in loss of investment trust status. Changes in tax legislation such as BEPS, WHT rules and structural requirements result in increased tax and resulting in a drop in returns from the Company’s investments. The corporate structure of the Company is reviewed periodically by the Company and its advisors. All investments receive professional structural advice prior to investment.

Political and associated economic risk

Exposure to Russia and/or Ukraine and the Middle East within the investment portfolio could lead to losses on investments. The impact on the global equity markets, and hydrogen stocks in particular, of a prolonged downturn caused by the situation in Ukraine and the Middle East, could lead to reduced valuations of the Company. The current US administration’s aggressive foreign policy regarding trade tariffs has had significant impact on financial markets and depending on where tariff levels settle, may have a significant impact on the global trade landscape. The Board and Investment Adviser have reviewed the portfolio for exposure and will continue to keep this under review.

Viability statement

The Directors have assessed the viability of the Group for the period to 31 December 2027 (the “Viability Period”). The Board believes that the Viability Period, being approximately three years, is an appropriate time horizon over which to assess the viability of the Group, particularly when taking into account the long-term nature of the Group’s investment strategy, of investing in private equity stakes of unlisted companies with a 3-5 year exit plan for each investment, the principal risks outlined on pages 41 to 43 and the continuation vote due in 2026. The viability period has been reduced from five years on account of the financial situation of the Company and the impending continuation vote. This assessment has been made on the assumption that the cashflow shortfall is resolved by the action plans laid out in Note 2 Basis of Preparation in the Financial Statements, which the Board consider to be achievable, based on the progress on cost cutting made to date and the Company’s ability to realise part of its investment portfolio through secondary sales.

HydrogenOne Capital Growth plc Annual Report 2024 FUTURE FUEL. NOW 44

In accordance with the Articles, the continuation of the Company is subject to the approval of shareholders every five years, with the first vote to be proposed as an ordinary resolution at the Company’s AGM in 2026. If passed, the Articles provide that the Directors propose as an ordinary resolution that the Company continue its business as presently constituted at each fifth annual general meeting thereafter that the Company continues its business as presently constituted. In its assessment of the prospects of the Group, the Board carried out a robust assessment of the emerging and principal risks and considered each of the uncertainties set out in the Annual Report which included consideration of severe but plausible downside scenarios (such as a long- term market downturn, significantly increased costs, delays in the realisation of assets and the liquidity and solvency of the Group). In the event that continuation vote is not passed, the Directors are required to draw up proposals for shareholders’ approval for the reconstruction or reorganisation of the Company, which would require a special resolution of the shareholders. The Board notes the current liquidity position of the Company and the high discount to NAV of the current share price, and recognises this increases the risk that the continuation vote will not be passed. The Board believe the actions to improve liquidity described in Note 2 Basis of Preparation in the Financial Statements will put the Company in a stronger position over the coming year, and the performance of the remaining Private Hydrogen Assets and the expected growth in the clean energy and hydrogen sectors, driven by increased governmental support, mean the prospects for the Company remain positive and this will be reflected in improved performance of the Company over the next twelve months, The Investment Adviser continues to implement all options to sustain the financial position of the Company as described in Note 2 Basis of Preparation in the Financial Statements. Measures that are being undertaken include reducing costs, a strategy to divest of portfolio positions in full or in part, and accessing debt as set out in the Company’s investment policy. The Board considered the Group’s current financial position and its ability to raise funds to meet the Group’s liabilities over the next twelve months and beyond. The Board considered each of the actions currently being taken to address the financial situation, and the likelihood of success for each of the actions. In addition, it considered the impact these actions would have on the viability of the Group. The Board also considered the Group’s income and expenditure projections and cash projections. These metrics were subjected to stress testing of the assumptions to evaluate the potential impact on the Group, longer investment hold periods and increased inflation.# Governance

Portfolio changes, market developments, level of premium / discount to NAV and share buybacks / share issues are discussed at quarterly Board meetings. The internal control framework of the Group is subject to a formal review on at least an annual basis. The level of the ongoing charges is dependent to a large extent on the level of net assets, the most significant contributor being the Investment Adviser’s fee. The Group’s cash realisable from the sale of its investments provide cover to the Group’s operating expenses, and any other costs likely to be faced by the Group over the Viability Period of their assessment. The Director’s assessment considered the market risks associated with the Russian invasion of Ukraine and the war in the Middle East, along with the likely impact of the current global government policy affecting the hydrogen sector and the tariffs being implemented by the new US administration. The ongoing market volatility and uncertainty this has caused, including higher inflation and interest rates, has been considered and will continue to be monitored. The Investment Adviser has reviewed the investment portfolio for exposure and while limited exposure has been identified the Board will keep the situation under continued review. Based on this assessment, the Directors have a reasonable expectation that the Group will be able to continue to operate and to meet its liabilities as they fall due over the Viability Period.

Employees

The Company has no employees. As at the date of this report, the Company had four Directors, of whom two are male and two are female.

Outlook

The outlook for the Company is described in the Chairman’s Statement and the Investment Adviser’s Report.

Up to 14 November 2022, the NAV per Ordinary Share was calculated on a daily basis based upon the quarterly valuation of the Private Hydrogen Assets and daily valuation of the Listed Hydrogen Assets. Since 15 November 2022 the NAV per Ordinary Share has been calculated on a quarterly basis based upon the quarterly valuation of the Private Hydrogen Assets and Listed Hydrogen Assets. The quarterly NAV per Ordinary Share is published through a regulatory information service.

Retail distribution promotion

As a result of the Financial Conduct Authority (“FCA”) rules determining which investment products can be promoted to retail investors, certain investment products are classified as ‘non-mainstream pooled investment’ products and face restrictions on their promotion to retail investors. The Company has concluded that the distribution of its shares, being shares in an investment trust, is not restricted as a result of the FCA rules described above. The Company currently conducts its affairs so that the shares issued by the Company can be recommended by financial advisers to retail investors and intends to continue to do so for the foreseeable future.# Shareholder relations and Annual General Meeting (AGM)

The Investment Adviser has a programme of meetings with shareholders and reports back to the Board on its findings. The Board also welcomes direct feedback from shareholders. The Chairman is available to meet shareholders and may be contacted by email via the Company Secretary at [email protected]. The Board encourages all shareholders to attend the AGM and generally seeks to provide twenty-one clear days’ notice of that meeting. The separate Circular and Notice of AGM sets out the business of the AGM and any special business is explained in the Directors’ Report on pages 47 and 48. Separate resolutions are proposed for each substantive issue. The Company’s AGM will be held on 27 June 2025 and the Chairman’s Statement on page 7 sets out the arrangements for the meeting have the opportunity to hear a presentation from the Investment Adviser and ask questions of the Board and the Investment Adviser. All shareholders are advised to submit their proxy form in advance of the AGM. Details of how shareholders can cast their votes can be found in the separate Circular and Notice of AGM which will be sent to all shareholders entitled to receive such notice following the Annual Report.

Special business of the AGM

Authority to issue and purchase own shares

The Board recommends that the Company be granted a new authority to allot up to a maximum of 12,881,999 Ordinary Shares (representing approximately 10% of the Ordinary Shares in issue at the date of this document) and to dis-apply pre-emption rights when allotting those Ordinary Shares and/or selling Ordinary Shares from treasury. Ordinary resolution 10 and special resolution 11 will be put to shareholders at the AGM. Ordinary Shares will be issued under this authority only at the Board’s discretion and when it is deemed to be in the best interests of shareholders as a whole to do so. The advantages are to lower the Company’s ongoing charges as expenses are diluted and, in the short term, to address volatility in the share price. Unless otherwise authorised by shareholders, new Ordinary Shares will not be issued at less than NAV and Ordinary Shares held in treasury will not be sold at less than NAV. The maximum number of Ordinary Shares which can be admitted to trading on the London Stock Exchange without the publication of a prospectus is 20% of the Ordinary Shares on a rolling previous 12-month basis at the time of admission of the Ordinary Shares.

The Directors recommend that a new authority to purchase up to 19,310,117 Ordinary Shares (subject to the condition Directors’ Report FUTURE FUEL. NOW 48 HydrogenOne Capital Growth plc Annual Report 2024 Directors’ Report that not more than 14.99% of the Ordinary Shares in issue at the date of the AGM are purchased) be granted and special resolution 12 to that effect will be put to the AGM. Any Ordinary Shares purchased will either be cancelled or, if the Directors so determine, held in treasury. Ordinary Shares are purchased at the discretion of the Board and when it is deemed to be in the best interests of shareholders. Ordinary Shares will be purchased for cancellation or for treasury only when the Ordinary Shares are trading at a discount to the Net Asset Value. The Companies Act 2006 allows companies to hold shares acquired by way of market purchases as treasury shares, rather than having to cancel them. This gives the Company the ability to sell Ordinary Shares quickly and cost effectively, thereby improving liquidity and providing the Company with additional flexibility in the management of its capital base. At the year end and at the date of this report, no Ordinary Shares were held in treasury.

Notice of General Meetings

Special resolution 13 in the separate Circular and Notice of AGM is required to reflect the requirements of the Shareholder Rights Directive. The Company is currently able to call general meetings, other than an AGM, on 14 clear days’ notice and would like to preserve this ability. In order to be able to do so, shareholders must have given their prior approval. Special resolution 13 seeks such approval, which would be effective until the Company’s next AGM, when it is intended that a similar resolution will be proposed. The Company will ensure that it offers the facility for shareholders to vote by electronic means, and that this facility is accessible to all shareholders, if it is to call general meetings on 14 days’ notice. Short notice of this kind will be used by the Board only under appropriate circumstances.

Continuation vote

The Articles of Association require that an ordinary resolution be proposed at every fifth AGM of the Company that the Company should continue as an investment trust for a further five-year period. In accordance with the Articles of Association, the initial vote for the continuation of the Company will be proposed at the AGM to be held in 2026. In the event that such a resolution is not passed, the Directors are required to draw up proposals for shareholders’ approval for the reconstruction or reorganisation of the Company, which would require a special resolution of shareholders.

Management

The Board

The independent Board is responsible to Shareholders for the overall management of the Company. The Board has adopted a Schedule of Matters Reserved for the Board which sets out the division of responsibilities between the Board and its various committees, the Chairman and the Chairmen of the various committees, together with the duties of the Board, further details can be found on pages 51 and 52. Through the Committees and the use of external independent advisers, the Board manages risk and governance of the Company.

Appointment of Board Members

The rules concerning the appointment of Directors are contained in the Company’s Articles of Association which require that a Director shall be subject to election at the first AGM after appointment and annual re-election thereafter. Further details of the Board’s process for the appointment of Board members can be found on page 52.

Alternative Investment Fund Manager (“AIFM”)

FundRock Management Company (Guernsey) Limited has been appointed as the Company’s and Limited Partnership’s AIFM. The AIFM has delegated the provision of portfolio management services to the Investment Adviser pursuant to the Investment Adviser Agreement. The AIFM Agreement shall continue in force until terminated by either the AIFM or the Company by giving to the other no less than six months’ prior written notice, provided that such notice may not be served earlier than the date being twelve months from the date of the AIFM Agreement. The AIFM Agreement may be terminated earlier by either party with immediate effect in certain circumstances, including, if the other party shall go into liquidation or an order shall be made or a resolution shall be passed to put the other party into liquidation or the other party has committed a material breach of any obligation the AIFM Agreement, and in the case of a breach which is capable of remedy fails to remedy it within 30 days. Details of the fee the AIFM is entitled to receive are given in note 14 to the Financial Statements. The AIFM shall maintain, at its cost, professional indemnity insurance to cover any professional liability which it may incur under the AIFM Agreement, with a limit not less than £5,000,000. The Company has granted to the AIFM and certain other indemnified parties, a customary indemnity against losses which may arise in relation to the AIFM’s performance of its duties under the AIFM Agreement. The Board confirms that it has reviewed whether to retain FundRock Management Company (Guernsey) Limited as the AIFM of the Company. It has been concluded that it is in the best interests of shareholders as a whole to continue with the AIFM’s engagement.

Investment Adviser

The AIFM has appointed HydrogenOne Capital LLP as the Investment Adviser. The Investment Adviser has been given responsibility for investment advisory services in respect of any Private Hydrogen Assets the Company invests in directly or indirectly through holding entities and the Listed Hydrogen Assets (including uninvested cash) in accordance with the Company’s investment policy, subject to the overall control and supervision of the AIFM. Details of the Investment Advisory fees are given in note 6 to the Financial Statements. As at 31 December 2024, Dr JJ Traynor held 100,000 Ordinary Shares and Mr Richard Hulf held 100,000 Ordinary Shares in the Company.

The Investment Adviser Agreements are for an initial term of four years from the date of Admission and thereafter subject to termination on not less than twelve months’ written notice by any party. The Investment Adviser Agreements can be terminated at any time in the event of, inter alia, the insolvency of the Company, the AIFM or the Investment Adviser or if certain key members of the Investment Adviser’s team cease to be involved in the provision of services to the Company and are not replaced by individuals satisfactory to the Company (acting reasonably).# Directors' Report

The Company and the Limited Partnership have given an indemnity in favour of the Investment Adviser (subject to customary exceptions) in respect of the Investment Adviser’s potential losses in carrying on its responsibilities under the Investment Adviser Agreement. The Board confirms that it has reviewed whether to retain HydrogenOne Capital LLP as the Investment Adviser of the Company and the Limited Partnership. It has been concluded that, given the Investment Adviser’s depth of knowledge in the sector and the recent growth and performance record of the Company, it is in the best interests of shareholders as a whole to continue with the Investment Adviser’s engagement.

In accordance with the AIFMD, the AIFM must ensure that an annual report containing certain information on the Company is made available to investors for each financial year.

Political donations

There were no political donations made during the financial year to 31 December 2024.

Disclosure required by listing rule UKLR 6.6.1

The above rule requires listed companies to report certain information in a single identifiable section of their annual financial reports. The Company confirms that, other than the allotment of equity securities for cash (UKLR 6.6.1(6)) which is detailed in note 11 to the Financial Statements, all such reporting applied only to non-applicable events for the year ended 31 December 2024.

Future trends

Details of the main trends and factors likely to affect the future development, performance and position of the Company’s business can be found in the Investment Adviser’s Report section of this Strategic Report. Further details as to the risks affecting the Company are set out in the ‘Principal Risks and Uncertainties’ on pages 41 to 43.

Directors’ indemnities

Subject to the provisions of the Companies Act 2006 and certain provisions contained in the deeds of indemnity issued by the Company, the Company has indemnified each of the Directors against all liabilities which each Director may suffer or incur arising out of or in connection with any claim made or proceedings taken against them, or any application made under sections 661(3), 661(4) or 1157 of the Companies Act 2006 by them, on the grounds of their negligence, default, breach of duty or breach of trust, in relation to the Company or any associated company. The indemnities would provide financial support from the Company after the level of cover provided by the Company’s Directors’ and Officers’ insurance policy has been fully utilised.

Going concern

The Directors have considered the going concern position of the Company and recognise the current financial position of the Company. The actions being taken by the Board and the Investment Adviser as set out in the Viability Statement and Note 2 Basis of Preparation in the Financial Statements have been considered and the Directors believe that together they will improve the financial position of the Company. The Directors consider that the cash position and outlook mean that there are material uncertainties that may cast significant doubt on the Company’s ability to continue as a going concern. The Company’s strategy has been set to address this. Further cost savings are anticipated in 2025. The Company continues to seek both secondary sales of parts of its portfolio, and full exits from portfolio. The Company continues to monitor opportunities for a fresh equity raise, although the discount of the share price to the NAV may prevent this. In addition the Company is engaged with lenders to potentially access debt for the fund. The Board and the Investment Adviser are considering a wide range of options, with urgency, to deliver shareholder value, with confidential discussions underway with third parties. Please refer to Note 2 Basis of Preparation in the Financial Statements for further details on these plans.

Auditor information

Each of the Directors at the date of the approval of this report confirms that: (i) so far as the Director is aware, there is no relevant audit information of which the Company’s auditor is unaware; and (ii) the Director has taken all steps that he or she ought to have taken as Director to make himself or herself aware of any relevant information and to establish that the Company’s auditor is aware of that information. This confirmation is given and should be interpreted in accordance with the provisions of Section 418 of the Companies Act 2006.

Appointment of auditor

In accordance with Section 489 of the Companies Act 2006, a resolution will be put forward at the forthcoming AGM on 27 June 2025 to re-appoint KPMG Channel Islands Limited (“KPMG”) as auditor.

Corporate Governance

Introduction

This Corporate Governance statement forms part of the Directors’ Report. The Listing Rules and the Disclosure Guidance and Transparency Rules of the UK Listing Authority require listed companies to disclose how they have applied the principles and complied with the provisions of The UK Corporate Governance Code 2018 (the “UK Code”), as issued by the Financial Reporting Council (“FRC”). The UK Code can be viewed on the FRC’s website.

The Board has considered the principles and provisions of the AIC Code of Corporate Governance 2019 (the “AIC Code”) which addresses those set out in the UK Code, as well as setting out additional provisions on issues that are of specific relevance to the Company, as an investment trust. The Board considers that reporting against the AIC Code, which has been endorsed by the Financial Reporting Council, provides more relevant information to shareholders. The AIC Code is available on the AIC website (www. theaic. co.uk). It includes an explanation of how the AIC Code adapts the Principles and Provisions set out in the UK Code to make them relevant for investment companies.

The Company has complied with the AIC Code and the relevant provisions of the UK Code, except as set out below. The UK Code includes provisions relating to:
* the role of the chief executive (provision 14);
* the need for an internal audit function (provision 25); and
* executive Directors’ remuneration (provision 33).

The Board considers these provisions are not relevant to the Company, being an externally managed investment company with no employees. The Company has therefore not reported further in respect of these provisions, other than the need for an internal audit function specific to the Company, which has been addressed on page 60.

The Board Composition

At the date of this report the Board consists of four Non-Executive Directors. The Chairman is Simon Hogan, and the Directors are Afkenel Schipstra, Abigail Rotheroe and Erik Magnesen. David Bucknall served throughout the year and on 21 March 2025, stepped down and was replaced by Erik Magnesen. Simon Hogan, and Afkenel Schipstra were appointed as Non-Executive Directors 22 May 2021, Abigail Rotheroe 8February 2022 and Erik Magnesen 21 March 2025.# Corporate Governance

Due to the size and nature of the Company’s business, the Board has not deemed it necessary to appoint a Senior Independent Director as the role can be performed by the Board as a whole. The Board believes that during the year ended 31December 2024 its composition was appropriate for an investment company of the Company’s nature and size. All of the Directors are independent of the Investment Adviser and are able to allocate sufficient time to the Company to discharge their responsibilities effectively. The Directors have a broad range of relevant experience to meet the Company’s requirements and their biographies are provided on page 46.

In accordance with the Co-Investment Agreement between INEOS Energy and the Company, Mr Bucknall throughout the year and now Mr Magnesen have recused themselves from any decision relating to a transaction by the Company or any member of the Group with INEOS Energy or any of its Associates. The Board has noted the inference of the provisions in the AIC Code that Non-Executive Directors who represent a significant shareholder should be presumed not to be independent. However, it is the Board’s assessment that the provisions in place to manage actual or potential situational conflicts of interest are sufficiently robust and always promote the success of the Company. The Board has concluded that during the year, Mr Bucknall demonstrated independence of character and judgement. His skills and experience have added significantly to the strength of the Board and his continued service has been invaluable to the long-term success of the Company. The Board believe that Mr Magnesen will be a great addition to the Board and will provide the same independence of character and judgement.

In line with the AIC Code and the Articles of Association, each Director is subject to election at the first AGM following their appointment and annual re-election thereafter by shareholders. The Board recommends all the Directors for election or re-election. The Directors have appointment letters which do not provide for any specific term. Copies of the Directors’ appointment letters are available on request from the Company Secretary. Upon joining the Board, any new Director will receive an induction and relevant training is available to Directors on an ongoing basis. A policy of insurance against Directors’ and Officers’ liabilities is maintained by the Company. The Directors, in the furtherance of their duties, may take independent professional advice at the expense of the Company.

Board Committees

The Board decides upon the membership and chairmanship of its committees. Each Committee has adopted formal terms of reference, which are reviewed at least annually, and copies of these are available on the Company’s website or on request from the Company Secretary. As the Board is small and comprises of only non-executive Directors, Simon Hogan, Afkenel Schipstra and Abigail Rotheroe are members of each of the Board Committees. Erik Magnesen and David Bucknall throughout the year are invited to attend.

Audit and Risk Committee

A report on pages 59 and 60 provides details of the role and composition of the Audit and Risk Committee together with a description of the work of the Audit and Risk Committee in discharging its responsibilities.

Remuneration Committee

Abigail Rotheroe is the Chairman. The Remuneration Committee has been established to meet formally on at least an annual basis to review the remuneration policy of the Company and consider the fees of the Non-Executive Directors. The Directors’ Remuneration Implementation Report is included on pages 56 and 58.

Management Engagement Committee (“MEC”)

Abigail Rotheroe is the Chairman. The MEC has been established to conduct a formal annual review of the AIFM and the Investment Adviser, assessing investment and other performance, the level and method of their remuneration and the continued appointment of them as AIFM and Investment Adviser to the Company. The MEC met and reviewed the AIFM and Investment Adviser’s performance and remuneration structure. In conclusion the Committee’s recommendation to the Board was that it was in the best interests of shareholders as a whole to continue with their engagements and that the current management fee structure remained appropriate. (Seepage 56 for further details).

During the year, the MEC also conducted an annual detailed service review of the main service providers to the Company and concluded that their continued appointment remained in the best interest of shareholders.

Nomination Committee

Simon Hogan is the Chairman. The Nomination Committee has been established for the purpose of identifying and putting forward candidates for the office of Director of the Company. The Nomination Committee considers job specifications and assesses whether candidates have the necessary skills and time available to devote to the job. It also undertakes an annual performance evaluation of the Board. An evaluation requiring the Directors to complete detailed questionnaires on the operation of the Board, its committees and the individual contribution of Directors as well as the performance of the Chairman was undertaken during the year. The results of the evaluation were reviewed by the Chairman and discussed with the Board. Based upon the conclusions of the most recent performance evaluation, which were positive and demonstrated that the Directors showed the necessary commitment for the effective fulfilment of their duties, the Committee recommended that each of the Directors be re-elected or elected at the forthcoming AGM. The Board succession plan is reviewed and maintained through the Nomination Committee to promote regular refreshment and diversity, whilst maintaining stability and continuity of skills and knowledge on the Board.

Valuation Committee

Afkenel Schipstra is the Chairman. The Valuation Committee has been established to meet formally on at least a quarterly basis to formulate valuation policies for investments of the Company, consider whether independent valuation of the portfolio is required and approve the valuations or valuation methodology of the Private and Listed Hydrogen Assets. A summary of the valuation of the Company’s investment portfolio is given on page 22.

Board diversity

Appointments are based on merit with due regard to the benefits of diversity. The Board considers many factors, including the balance of skills, knowledge, experience, gender, ethnicity, cognitive and personal strengths when reviewing its composition and appointing new Directors. The aim of the policy is to identify those with the best range of skills and experience to complement existing Directors in order to provide effective oversight of the Company and constructive support and challenge to the Investment Adviser.

Summary biographical details of the Directors, including their relevant experience, are set out on page 46.

The Board currently comprises four Non-Executive Directors of which two are female thereby constituting 50% female representation and complies with the Hampton Alexander target of 33% female membership. However, although the Board has considered the recommendations of the Davies and Hampton-Alexander reviews as well as the Parker review, it does not consider it appropriate to establish targets or quotas in these regards.

The Company has no employees. The Board take account of the targets set out in the FCA’s Listing Rules, that i) 40% of a board should be women, ii) at least one senior role should be held by a woman; and iii) at least one board member should be from a non-white ethnic background as defined by the Office of National Statistics criteria.

The Board voluntarily discloses the following information in relation to its diversity. As an externally managed investment company, the Board employs no executive staff and therefore does not have a chief executive officer (CEO) or a chief financial officer (CFO)- both of which are deemed senior board positions by the FCA. However, the Board considers the Chair of the Audit and Risk Committee to be a senior board position and the following disclosure is made on this basis. The other applicable senior board position as recognised by the FCA is Chair of the Board. In addition, the Board has resolved that the Company’s year end date be the most appropriate date for disclosure purposes. The following information has been provided by each Director. There have been no changes since 31 December 2024.

Board as at 31 December 2024

Number of Board members Percentage of the Board Number of senior positions on the Board
Men 2 50 1
Women 2 50 1
Prefer not to say
Number of Board members Percentage of the Board Number of senior positions on the Board
White British or Other White (including minority- white groups) 4 100 2
Prefer not to say

The Company has met the Listing Rule targets i and ii in respect of Gender equality but has not yet met the target on ethnic diversity.# Governance

Board Diversity and Succession Planning

The Board recognises the benefits of having diverse representation reflecting wider society within the Board and is committed to ensuring that its composition reflects ethnic diversity, and it is looking to make meaningful progress on this front when appropriate and as part of its succession planning. Due to the nature and size of the Company, the Board comprises of four directors. The Board considers this to be the principal reason why the Listing Rule target has not been met.

Tenure Policy

It is the Board’s policy that all Directors, including the Chairman, shall normally have tenure limited to nine years from their appointment to the Board, except that the Board may determine otherwise if it is considered that the continued participation on the Board of an individual Director is in the best interests of the Company and its shareholders. This is also subject to the Director’s re-election annually by shareholders. The Board considers that this policy encourages regular refreshment and is conducive to fostering diversity.

Internal Control

The Board is responsible for establishing the Company’s system of internal controls and for monitoring their effectiveness. The system of internal controls is designed to manage rather than eliminate the risk of failure to achieve business objectives. It can provide only reasonable assurance against material misstatement or loss. The Board, through the Audit and Risk Committee, regularly reviews the effectiveness of the internal control systems to identify, evaluate and manage the Company’s significant risks. If any significant failings or weaknesses are identified the Board, and where required the Investment Adviser, ensure that necessary action is taken to remedy the failings. Taking into account the principal risks and uncertainties section on pages 41 to 43 during the year, the Board – through the Audit and Risk Committee – established the Company’s risk management framework and controls. This identified a detailed number of risks facing the Company and resulted in enhanced risk documentation and reporting to the Board and Audit and Risk Committee. Following its review, the Board is not aware of any significant failings or weaknesses arising in the year under review.

FUTURE FUEL. NOW 54
HydrogenOne Capital Growth plc Annual Report 2024

The Board believes that the existing arrangements, including those set out below, represent an appropriate framework to meet the internal control requirements. By these procedures the Directors have kept under review the effectiveness of the internal control system throughout the year and up to the date of this report.

Financial Aspects of Internal Control

These are detailed in the Report of the Audit and Risk Committee.

Other Aspects of Internal Control

The Board holds at least four regular meetings each year, plus additional meetings as required. Between these meetings there is regular contact with the Investment Adviser and the Company’s Administrator and Company Secretary. The Administrator, Apex Listed Companies Services (UK) Limited reports separately in writing to the Board concerning risks and internal control matters within its remit, including internal financial control procedures and company secretarial matters. Additional ad hoc reports are received as required and Directors have access at all times to the advice and services of the Company Secretary, which is responsible to the Board for ensuring that Board procedures are followed and that applicable rules and regulations are complied with. The contact with the Investment Adviser, the AIFM and the Administrator enable the Board to monitor the Company’s progress towards its objectives and encompass an analysis of the risks involved. The effectiveness of the Company’s risk management and internal controls systems is monitored regularly and a formal review, utilising a detailed risk assessment programme, takes place at least annually. This includes review of the internal controls reports of the Administrator, the AIFM and the Registrar.

Principal Risks

The Directors confirm that they have carried out a robust assessment of the Company’s emerging and principal risks, including those that would threaten its business model, future performance, solvency or liquidity. The principal risks and how they are being managed are set out in the Strategic Report on pages 41 to 43.

Directors’ Remuneration Policy

The remuneration policy (the “Policy”) must be put forward for shareholder approval at its first AGM and thereafter at a maximum interval of three years. The Policy was last approved by shareholders at the AGM held on 24 May 2022 and will be submitted for shareholder approval at the forthcoming Annual General Meeting to be held on 27 June 2025. The provisions set out in the Policy apply until they are next submitted for shareholder approval. In the event of any proposed material variation to the Policy, shareholder approval will be sought for the proposed new policy prior to its implementation. The Policy sets out the principles the Company follows in remunerating Directors and the result of the shareholder vote on the Policy is binding on the Company. The Remuneration Committee will take account of any views expressed by shareholders in formulating this policy. All the Directors are Non-Executive Directors, and the Company has no other employees.

Service Contracts

The Directors do not have service contracts with the Company. The Directors have appointment letters and following initial election by shareholders, are subject to annual re-election.

Fees

Directors’ fees are determined by the Board according to their duties and responsibilities and by reference to the time commitment required by each Director to carry out their roles effectively. In setting fees, the Board also has regard to the need to recruit and retain Directors with appropriate knowledge and experience, the fees paid to Directors of the Company’s peers and industry practice. Directors’ fees are also subject to the aggregate annual limit set out in the Company’s Articles of Association (the “Articles”), which is £300,000. The aggregate limit of Directors’ fees in the Articles can only be amended by an ordinary resolution put to shareholders at a general meeting. Directors are not eligible for bonuses, pension benefits, share benefits, share options, long-term incentive schemes or other benefits. Directors’ fees are paid at fixed annual rates and do not have any variable elements. Directors are also entitled to be reimbursed for all reasonable out-of-pocket expenses incurred in performance of their duties. These expenses are unlikely to be of a significant amount. Fees are payable from the date of appointment as a Director of the Company and cease on the date of termination of appointment. Any new Directors will be paid at the same rate as existing Directors. Directors are not entitled to compensation for loss of office, and there is no notice period upon early termination of appointment. No incentive fees will be paid to any person to encourage them to become a Director of the Company. The Company may, however, pay fees to external agencies to assist the Board in the search and selection of Directors or in reviewing remuneration. Where a consultant is appointed, the consultant shall be identified in the Annual Report alongside a statement about any other connection it has with the Company or individual Directors. No consultants were appointed during the year. Independent judgement will be exercised when evaluating the advice of external third parties.

Statement of Consideration of Conditions Elsewhere in the Company

As stated above, the Company has no employees. Therefore, the process of consulting with employees on the setting of the Remuneration Policy is not applicable.

Review of the Policy

This Policy will be reviewed on an annual basis by the Remuneration Committee and any changes approved by the Board. As part of the review, the Remuneration Committee will consider whether the Policy supports the long-term success of the Company and takes into consideration all relevant regulatory requirements. Any material change to the Policy must be approved by shareholders.

Effective Date

The Policy is effective from the date of approval by shareholders.

Directors’ Remuneration Implementation Report

This Directors’ Remuneration Implementation Report (“the Report”) has been prepared in accordance with Schedule 8 of the Large and Medium-sized Companies and Groups (Accounts and Reports) (Amendment) Regulation 2013. An ordinary resolution for the approval of this Report will be put forward at the forthcoming AGM. The Report is put forward for approval by shareholders on an annual basis. The result of the shareholder resolution on the Report is non-binding on the Company, although it gives shareholders an opportunity to express their views, which will be taken into account by the Board and the Remuneration Committee. The law requires the Company’s auditor to audit certain of the disclosures provided. Where disclosures are audited, they are indicated as such. The auditor’s opinion is shown on pages 62 to 68.# Remuneration Committee

The Company currently has four (2023: four) Non-Executive Directors. In accordance with clause 5 of the Relationship and Co-Investment Agreement, INEOS Energy is entitled to nominate one Non-Executive Director for appointment to the Board. Erik Magnesen has been nominated for this purpose, and as set out in his appointment letter, is not remunerated for his role as a Non-Executive Director.

During the year, the annual fee payable to the Chair of the Board was £68,250, the Chair of the Audit and Risk and Valuation Committees, £57,750 and Chair of the Management Engagement and Remuneration Committees, £47,250.

The Remuneration Committee reviewed the level of Directors’ fees and recommended to the Board that no change should be made to the rate of fees paid to Directors. The Remuneration Committee believes that the level of fees appropriately reflects prevailing market rates for an investment trust of the Company’s complexity and size, the increasing complexity of regulation and resultant time spent by the Directors on matters and will also enable the Company to attract appropriately experienced additional Directors in the future.

The annual fees of the Directors from 1 January 2024 are as follows:

Name Role Fee
Simon Hogan Chair £68,250
Afkenel Schipstra Chair of the Audit and Risk and Valuation Committees £57,750
Abigail Rotheroe Chair of the Remuneration and Management Engagement Committee £47,250
David Bucknall Non-Executive Director
Erik Magnesen Non-Executive Director

The Remuneration Committee comprises the whole Board with the exception of Mr Magnesen and Mr Bucknall throughout the year. Further detail on the duties of the Remuneration Committee can be found in the Corporate Governance statement on page 52.

The maximum level of fees payable, in aggregate, to the Directors of the Company is £300,000 per annum as set out in the Company’s Articles of Association.

Directors’ appointment letters and shareholding rights

The Directors have appointment letters which do not provide for any specific term. The Directors are not entitled to compensation on loss of office. There are no restrictions on transfers of the Company’s Ordinary Shares held by the Directors, or any special rights attached to such shares.

Performance

The chart below shows the performance of the Company’s share price by comparison to the Solactive Hydrogen Economy Index on a total return basis. The Company does not have a specific benchmark but has deemed the Solactive Hydrogen Economy Index to be the most appropriate as at least 60% of the companies included in the index generate 100% of their revenue from clean Hydrogen.

Report of the Audit and Risk Committee

As Chairman of the Audit and Risk Committee (the “Committee”), I am pleased to present the Committee’s report to shareholders for the year ended 31 December 2024.

The Audit and Risk Committee Composition

Afkenel Schipstra is the Chairman of the Audit and Risk Committee. In accordance with the UK Code, the Chairman of the Board should not be a member. However, the AIC Code permits the Chairman of the Board to be a member of but not chair the Committee if they were independent on appointment – which the Chairman was and continues to be. In view of the size of the Board, the Directors feel it is appropriate for him to continue as a member, so that the Committee can continue to benefit from his experience and knowledge. The members of the Committee consider that they have the requisite skills and experience to fulfil the responsibilities of the Committee. The Committee considers that at least one of its members has recent and relevant financial experience and competence relevant to the sector in which the Company operates.

Role and responsibilities

The main role and responsibilities of the Committee are set out in the Committee’s terms of reference. The terms are updated annually and are available on the Company’s website or on request from the Company Secretary. The Committee meets formally at least twice a year for the purpose, amongst other things, of advising the Board on the appointment, effectiveness, independence, objectivity and remuneration of the external auditor.

The Committee monitors the integrity of the Financial Statements of the Company and any formal announcements relating to the Company’s financial performance, reviewing significant financial reporting judgements contained in them. The Committee also reviews the Company’s risk management, internal financial controls and internal control systems and reviews the Investment Adviser’s whistleblowing arrangements. The provision of non-audit services by the auditor are reviewed against the Committee’s policy described overleaf.

Meetings

There were four Committee meetings during the year ended 31 December 2024. In addition, the Committee met the auditor, without any other party present, for a private discussion and the Chairman of the Committee met with the auditor prior to the Audit Committee meeting held in April 2025.# Financial statements and significant accounting matters

The Committee reviewed the Financial Statements and considered the following significant accounting matters in relation to the Company’s Financial Statements for the year ended 31 December 2024.

Valuation of Private Hydrogen Assets investments

The Company’s investment through the Limited Partnership as at 31 December 2024 was £113,489,979 representing a substantial portion of the Company’s net assets and as such is the biggest factor in relation to the accuracy of the Financial Statements. The valuation of the Company’s Private Hydrogen Assets held through the Limited Partnership is the most material matter in the production of the Financial Statements. The Board has appointed a Valuation Committee which sets out the valuation policies and process. The Committee met four times during the year to review the valuations at each quarter end date. The process includes considering and approving valuations or valuation methodology made by the Investment Adviser and provided to the AIFM, using fair market valuations of the Listed and Private Hydrogen Assets on a quarterly basis as at 31 March, 30 June, 30 September and 31 December each year.

The valuation principles used to calculate the fair value of the Private Hydrogen Assets are based on IPEV Guidelines. For Private Hydrogen Assets, as the Company typically invests in early stage, pre or early revenue investments, a number of valuation methodologies in line with IPEV Guidelines have been considered and employed to value the investments including Discounted Cash Flow and Price of Recent Investment. The Valuation Committee reviewed and approved the appropriateness of the valuation methodology employed and the assumptions and made in the calculation of the fair value of each of the Private Hydrogen Assets. Details of the valuation methodology and assumptions used for each of the Private Hydrogen Assets as at 31 December 2024 are given in note 3 to the Financial Statements. The Audit and Risk Committee reviewed, along with the Valuation Committee, the procedures in place for ensuring the appropriate valuation of investments and approved the valuation of the Company’s Private Hydrogen Assets at the year end with the Investment Adviser and AIFM.

Going concern

Preparation of the Financial Statements on a going concern basis and the company viability is the other material matter in the production of the Financial Statements. The Audit and Risk Committee consider the financial situation of the Company at each Committee meeting and review all actions being taken to address the current situation. The Committee reviews the going concern assessment for the Company and long-term viability of it. The Committee has considered the financial situation of the Company and agree with the plans being undertaken by the Board and Investment Adviser to improve the cash position and outlook of the Company. The Committee also notes the material uncertainties that may cast significant doubt on the Company’s ability to continue as a going concern.

HydrogenOne Capital Growth plc Annual Report 2024

Emerging risks

The Committee considered the risks and economic impacts including higher inflation and interest rates arising from the Russian invasion of Ukraine and war in the Middle East, on the Company’s ability to continue in operation and impact on the Company’s portfolio and concluded that these had been properly reflected in the portfolio companies valuations and the Company’s Financial Statements.

As part of the annual report review, the Committee:

  • obtained assurances from the Investment Adviser and the Administrator that the Financial Statements had been prepared appropriately;
  • reviewed the consistency of, and any changes to, accounting policies;
  • reviewed the tax compliance of the Company during the year with the eligibility conditions and ongoing requirements in order for investment trust status to be maintained;
  • reviewed the Company’s financial resources and concluded that it is appropriate for the Company’s Financial Statements to be prepared on a going concern basis with material uncertainty as described in the Directors’ Report on page 50;
  • considered the risk to the Company from economic conditions such as higher interest rates and inflationary pressures and market volatility arising from the ongoing wars in Ukraine and the Middle East. The Board and the Investment Adviser have reviewed the investment portfolio and identified limited direct impact on the portfolio but continue to monitor any impact to the Company, the Group, its investee companies and overall valuations; and
  • concluded that the Annual Report for the year ended 31 December 2024, taken as a whole, is fair, balanced and understandable and provides the information necessary for shareholders to assess the Company’s position and performance, business model and strategy.

The Committee reached this conclusion through a process of review of the document and enquiries to the various parties involved in the production of the Annual Report. The Committee reported the results of this work, including its assessment that the Annual Report is fair, balanced and understandable, to the Board.

External auditor

This year’s audit was the fourth conducted by KPMG Channel Islands Limited (“KPMG”) and by David Alexander as audit Director, since KPMG was selected as the Company’s auditor at the Company’s launch and formal appointment on 15 June 2021. The appointment of the auditor is reviewed annually by the Audit and Risk Committee and the Board and is subject to approval by Shareholders. In accordance with the FRC guidance, the audit will be put out to tender within ten years of the initial appointment of KPMG. Additionally, the audit Director must be rotated every five years and is next eligible for rotation in 2026.

Effectiveness of audit

The Committee reviewed the audit planning and the standing, skills and experience of the firm and the audit team. The Committee also considered the independence of KPMG and the objectivity of the audit process. KPMG has confirmed that it is independent of the Company and has complied with relevant auditing standards. No modifications were required to the external audit approach. The Audit Plan was presented to the Audit and Risk Committee at its November 2024 Committee meeting, ahead of the commencement of the Company’s year end audit. The Audit Plan set out the audit process, materiality scope and significant risks. A presentation of the results of the audit following completion of the main audit testing was provided at the April 2025 meeting. Additionally, the Committee received feedback from the Investment Adviser and Administrator regarding the effectiveness of the external audit process. The Committee is satisfied that KPMG has provided effective independent challenge in carrying out its responsibilities. After due consideration, the Committee recommended the reappointment of KPMG and a resolution will be put forward to the Company’s shareholders at the 2025 AGM.

Provision of non-audit services

The Committee has put in place a policy on the supply of any non-audit services provided by the external auditor. Non-audit services are considered on a case-by-case basis and may only be provided to the Company if such services meet the requirements of the FRC’s Revised Ethical Standard 2024, including: at a reasonable and competitive cost; do not constitute a conflict of interest for the auditor; and all non-audit services must be approved in advance. No non-audit services were provided to the Company during the year to 31 December 2024.

Internal audit

The Audit and Risk Committee has considered the need for an internal audit function and considers that this is not appropriate given the nature and circumstances of the Company as an externally managed investment company with external service providers. The Audit and Risk Committee keeps the need for an internal audit function under periodic review.

Under company law the Directors must not approve the Financial Statements unless they are satisfied that they give a true and fair view of the state of affairs of the Group and Parent Company and of the Group’s profit or loss for that year.

In preparing each of the Group and Parent Company Financial Statements, the Directors are required to:

The Directors are responsible for keeping adequate accounting records that are sufficient to show and explain the Company’s transactions and which disclose with reasonable accuracy at any time the financial position of the Company and enable them to ensure that its Financial Statements comply with the Companies Act 2006. They are responsible for such internal control as they determine is necessary to enable the preparation of Financial Statements that are free from material misstatement, whether due to fraud or error, and have general responsibility for taking such steps as are reasonably open to them to safeguard the assets of the Group and to prevent and detect fraud and other irregularities.

Under applicable law and regulations, the Directors are also responsible for preparing a Strategic Report, Directors’ Report, Directors’ Remuneration Report and Corporate Governance Statement that complies with that law and those regulations. The Directors are responsible for the maintenance and integrity of the corporate and financial information included on the company’s website. Legislation in the UK governing the preparation and dissemination of Financial Statements may differ from legislation in other jurisdictions.

Responsibility statement of the Directors in respect of the annual report

The Directors each confirm to the best of their knowledge that:

Independent auditor’s report to the members of HydrogenOne Capital Growth plc

Our opinion is unmodified

We have audited the parent and consolidated financial statements of HydrogenOne Capital Growth plc (the “Company”) and its subsidiaries (together, the “Group”), which comprise the parent and consolidated statement of financial position as at 31 December 2024, parent and consolidated statements of comprehensive income, changes in equity and cash flows for the year then ended, and notes, comprising material accounting policies and other explanatory information.

In our opinion, the accompanying parent and consolidated financial statements:

  • give a true and fair view of the state of the Group’s and of the Company’s affairs as at 31 December 2024 and of the Group’s and the Company’s loss for the year then ended;
  • are properly prepared in accordance with UK-adopted international accounting standards; and
  • have been prepared in accordance with the requirements of the Companies Act 2006.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (“ISAs (UK)”) and applicable law. Our responsibilities are described below. We believe that the audit evidence we have obtained is a sufficient and appropriate basis for our opinion. Our audit opinion is consistent with our report to the audit committee.

We were first appointed as auditor by the Directors on 15 June 2021. The period of total uninterrupted engagement is for the four financial years ended 31 December 2024. We have fulfilled our ethical responsibilities under, and we remain independent of the Company and Group in accordance with, UK ethical requirements including the FRC Ethical Standard as applied to public interest entities. No non-audit services prohibited by that standard were provided.

Material uncertainty relating to going concern

| Key audit matter | The risk # Basis:

The Group and Company’s investment in the Limited Partnership is carried at fair value through profit or loss and represents a significant proportion of the Group and Company’s net assets. The fair value of the Limited Partnership has been determined as its net asset value, the most significant component of which is its underlying portfolio of non-controlling positions in unquoted hydrogen assets valued at £113,490,000 (2023: £126,206,000) (“Private Hydrogen Assets”). As Private Hydrogen Assets are unquoted and illiquid, their fair values are determined through the application of valuation techniques. The application of valuation techniques requires the exercise of judgements in relation to the selection of the valuation technique employed and the assumptions and data used in their application.

Our audit procedures included:

Control evaluation

We assessed the design and implementation of the Valuation Committee’s review control in relation to the valuation of Private Hydrogen Assets.

Challenging management’s valuation approach

For each of the Private Hydrogen Assets, with the support of our KPMG valuation specialist, we:
* held discussions with the Investment Adviser to understand the valuation approach; and
* assessed and challenged the appropriateness of the valuation approach and methodology applied for compliance with IPEV.

Key audit matter

| The risk | Our response |
| :---

valuation of the Limited Partnership

The risk

For the year ended 31 December 2024, Private Hydrogen Assets are valued, in accordance with the International Private Equity and Venture Capital Valuation 2022 (“IPEV”) Guidelines using the approach laid out in the “Valuation of the Limited Partnership” policy on pages 78 to 79, utilising either a discounted cash flow (“DCF”) technique; or net assets basis, (each a “Valuation Model”).

Risk: The valuation of Private Hydrogen Assets is a significant risk area of our audit given that they represent a substantial portion of the Group and Company’s net assets, and the selection and application of valuation techniques requires the exercise of judgements. The judgements inherent in the valuation approach may also expose the valuation of Private Hydrogen Assets to management bias. Therefore, there is a risk of material misstatement through error as well as a potential for fraud through possible management bias. We determined that the valuation of Private Hydrogen Assets have a high degree of estimation uncertainty giving rise to a potential range of reasonable outcomes greater than our materiality for the financial statements as a whole. The financial statements disclose in note 4 the sensitivities estimated by the Group and Company.

Valuation Model integrity, inputs and assumptions:

For each of the Private Hydrogen Assets we:
* tested the Valuation Model for mathematical accuracy including but not limited to material formula errors;
* corroborated material inputs used in the Valuation Model to supporting documentation;
* assessed and challenged the reasonableness of the assumptions applied in the Valuation Model;
* with the support of our KPMG valuation specialist, for those valued utilising a DCF technique, benchmarked the discount rate and key macro-economic assumptions applied in the Valuation Model to observable market data and our KPMG valuation specialist’s experience in valuing similar investments; and
* where relevant, considered market transactions in close proximity to the year- end and assessed their appropriateness as being representative of fair value.

Assessing disclosures:

We considered the appropriateness of the Group and Company’s investment valuation policies and the adequacy of the Group and Company’s disclosures in relation to the use of estimates and judgements in arriving at fair value. We assessed whether the disclosures around the sensitivities to changes in key assumptions reflect the risks inherent in the valuation of the Private Hydrogen Assets.

Our results

As a result of our procedures, we found the valuation of Private Hydrogen Assets and related disclosures to be acceptable.

Our application of materiality and an overview of the scope of our audit

Materiality for the parent and consolidated financial statements as a whole was set at £2,330,000, determined with reference to a benchmark of net assets of £116,439,000, of which it represents approximately 2.0% (2023: 2.0%).

In line with our audit methodology, our procedures on individual account balances and disclosures were performed to a lower threshold, performance materiality, so as to reduce to an acceptable level the risk that individually immaterial misstatements in individual account balances add up to a material amount across the parent and consolidated financial statements as a whole. Performance materiality for the Group and the Company was set at 75% (2023: 75%) of materiality for the parent and consolidated financial statements as a whole, which equates to £1,745,000. We applied this percentage in our determination of performance materiality because we did not identify any factors indicating an elevated level of risk.

We reported to the Audit and Risk Committee any corrected or uncorrected identified misstatements exceeding £116,500, in addition to other identified misstatements that warranted reporting on qualitative grounds.

Company Overview
Strategic Report
Governance
Financial statements
Other information

Our audit of the Group and Company was undertaken to the materiality level specified above, which has informed our identification of significant risks of material misstatement and the associated audit procedures performed in those areas as detailed above.

Going concern basis of preparation

The directors have prepared the parent and consolidated financial statements on the going concern basis as they do not intend to liquidate the Group or the Company or to cease their operations, and as they have concluded that the Group and the Company’s financial position means that this is realistic. They have also concluded that there are material uncertainties that could have cast significant doubt over their ability to continue as a going concern for at least a year from the date of approval of the parent and consolidated financial statements (the “going concern period”). An explanation of how we evaluated management’s assessment of going concern is set out in the “Material uncertainty relating to going concern” section of our report.

Our conclusions based on this work:
* we consider that the directors’ use of the going concern basis of accounting in the preparation of the parent and consolidated financial statements is appropriate; and
* we have nothing material to add or draw attention to in relation to the directors’ statement in note 2 to the parent and consolidated financial statements on the use of the going concern basis of accounting, and their identification therein of a material uncertainty that may cast significant doubt over the Group and the Company’s use of that basis for the going concern period, and that statement is materially consistent with the parent and consolidated financial statements and our audit knowledge.

However, as we cannot predict all future events or conditions and as subsequent events may result in outcomes that are inconsistent with judgements that were reasonable at the time they were made, the above conclusions are not a guarantee that the Group and the Company will continue in operation.

Fraud and breaches of laws and regulations – ability to detect

Identifying and responding to risks of material misstatement due to fraud

To identify risks of material misstatement due to fraud (“fraud risks”) we assessed events or conditions that could indicate an incentive or pressure to commit fraud or provide an opportunity to commit fraud. Our risk assessment procedures included:
* enquiring of management as to the Group’s policies and procedures to prevent and detect fraud as well as enquiring whether management have knowledge of any actual, suspected or alleged fraud;
* reading minutes of meetings of those charged with governance; and
* using analytical procedures to identify any unusual or unexpected relationships.

As required by auditing standards, and taking into account possible incentives or pressures to misstate performance and our overall knowledge of the control environment, we perform procedures to address the risk of management override of controls, in particular the risk that management may be in a position to make inappropriate accounting entries, and the risk of bias in accounting estimates such as valuation of Private Hydrogen Assets.

On this audit we do not believe there is a fraud risk related to revenue recognition because the Group and Company’s revenue streams are simple in nature with respect to accounting policy choice, and are easily verifiable to external data sources or agreements with little or no requirement for estimation from management. We did not identify any additional fraud risks.

We performed procedures including:
* identifying journal entries and other adjustments to test based on risk criteria and comparing any identified entries to supporting documentation;
* incorporating an element of unpredictability in our audit procedures; and
* assessing significant accounting estimates for bias.

Further detail in respect of valuation of Private Hydrogen Assets is set out in the key audit matter section of this report.

66 HydrogenOne Capital Growth plc Annual Report 2024

FUTURE FUEL.# Independent auditor’s report

Identifying and responding to risks of material misstatement due to non-compliance with laws and regulations

We identified areas of laws and regulations that could reasonably be expected to have a material effect on the parent and consolidated financial statements from our sector experience and through discussion with management (as required by auditing standards), and from inspection of the Group’s regulatory and legal correspondence, if any, and discussed with management the policies and procedures regarding compliance with laws and regulations. As the Group is regulated, our assessment of risks involved gaining an understanding of the control environment including the entity’s procedures for complying with regulatory requirements. The Group is subject to laws and regulations that directly affect the parent and consolidated financial statements including financial reporting legislation and taxation legislation and we assessed the extent of compliance with these laws and regulations as part of our procedures on the related financial statement items. The Group is subject to other laws and regulations where the consequences of non-compliance could have a material effect on amounts or disclosures in the parent and consolidated financial statements, for instance through the imposition of fines or litigation or impacts on the Group and the Company’s ability to operate. We identified financial services regulation as being the area most likely to have such an effect, recognising the regulated nature of the Group’s activities and its legal form. Auditing standards limit the required audit procedures to identify non-compliance with these laws and regulations to enquiry of management and inspection of regulatory and legal correspondence, if any. Therefore if a breach of operational regulations is not disclosed to us or evident from relevant correspondence, an audit will not detect that breach.

Context of the ability of the audit to detect fraud or breaches of law or regulation

Owing to the inherent limitations of an audit, there is an unavoidable risk that we may not have detected some material misstatements in the parent and consolidated financial statements, even though we have properly planned and performed our audit in accordance with auditing standards. For example, the further removed non-compliance with laws and regulations is from the events and transactions reflected in the parent and consolidated financial statements, the less likely the inherently limited procedures required by auditing standards would identify it. In addition, as with any audit, there remains a higher risk of non-detection of fraud, as this may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal controls. Our audit procedures are designed to detect material misstatement. We are not responsible for preventing non-compliance or fraud and cannot be expected to detect non-compliance with all laws and regulations.

Other information

The directors are responsible for the other information, which comprises the strategic report, the directors’ report and the other information included in the annual report, but does not include the parent and consolidated financial statements and our auditor’s report thereon. Our opinion on the parent and consolidated financial statements does not cover the other information and, accordingly, we do not express an audit opinion or, except as explicitly stated below, any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether, based on our parent and consolidated financial statements audit work, the information therein is materially misstated or inconsistent with the parent and consolidated financial statements or our audit knowledge. Based solely on that work:
* we have not identified material misstatements in the other information;
* in our opinion the information given in the strategic report and the directors’ report for the financial year is consistent with the parent and consolidated financial statements; and
* in our opinion those reports have been prepared in accordance with the Companies Act 2006.

Directors’ remuneration report

In our opinion the part of the Directors’ Remuneration Implementation Report to be audited has been properly prepared in accordance with the Companies Act 2006.

67 HydrogenOne Capital Growth plc Annual Report 2024 FUTURE FUEL. NOW Company Overview Strategic Report Governance Financial statements Other information

Disclosures of emerging and principal risks and longer term viability

We are required to perform procedures to identify whether there is a material inconsistency between the directors’ disclosures in respect of emerging and principal risks and the viability statement, and the parent and consolidated financial statements and our audit knowledge. Other than the material uncertainty related to going concern referred to above, we have nothing further material to add or draw attention to in relation to:
* the directors’ confirmation within the viability statement (pages 43 to 44) that they have carried out a robust assessment of the emerging and principal risks facing the Group, including those that would threaten its business model, future performance, solvency or liquidity;
* the emerging and principal risks disclosures describing these risks and explaining how they are being managed or mitigated;
* the directors’ explanation in the viability statement (pages 43 to 44) as to how they have assessed the prospects of the Group, over what period they have done so and why they consider that period to be appropriate, and their statement as to whether they have a reasonable expectation that the Group will be able to continue in operation and meet its liabilities as they fall due over the period of their assessment, including any related disclosures drawing attention to any necessary qualifications or assumptions.

We are also required to review the viability statement, set out on pages 43 to 44 under the Listing Rules. Based on the above procedures, we have concluded that the above disclosures are materially consistent with the parent and consolidated financial statements and our audit knowledge. Our work is limited to assessing these matters in the context of only the knowledge acquired during our parent and consolidated financial statements audit. As we cannot predict all future events or conditions and as subsequent events may result in outcomes that are inconsistent with judgements that were reasonable at the time they were made, the absence of anything to report on these statements is not a guarantee as to the Group’s and Company’s longer-term viability.

Corporate governance disclosures

We are required to perform procedures to identify whether there is a material inconsistency between the directors’ corporate governance disclosures and the parent and consolidated financial statements and our audit knowledge. Based on those procedures, we have concluded that each of the following is materially consistent with the parent and consolidated financial statements and our audit knowledge:
* the directors’ statement that they consider that the annual report and parent and consolidated financial statements taken as a whole is fair, balanced and understandable, and provides the information necessary for shareholders to assess the Group and Company’s position and performance, business model and strategy;
* the section of the annual report describing the work of the Audit and Risk Committee, including the significant issues that the Audit and Risk Committee considered in relation to the financial statements, and how these issues were addressed; and
* the section of the annual report that describes the review of the effectiveness of the Group and Company’s risk management and internal control systems.

We are required to review the part of Corporate Governance Statement relating to the Group and Company’s compliance with the provisions of the UK Corporate Governance Code specified by the Listing Rules for our review. We have nothing to report in this respect.

We have nothing to report on other matters on which we are required to report by exception

Under the Companies Act 2006, we are required to report to you if, in our opinion:
* adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or
* the parent company financial statements and the part of the Directors’ Remuneration Report to be audited are not in agreement with the accounting records and returns; or
* certain disclosures of directors’ remuneration specified by law are not made; or
* we have not received all the information and explanations we require for our audit.

We have nothing to report in these respects.

Respective responsibilities

Directors’ responsibilities

As explained more fully in their statement set out on page 61, the directors are responsible for:
* the preparation of the parent and consolidated financial statements including being satisfied that they give a true and fair view;
* such internal control as they determine is necessary to enable the preparation of parent and consolidated financial statements that are free from material misstatement, whether due to fraud or error;
* assessing the Group and Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern; and
* using the going concern basis of accounting unless they either intend to liquidate the Group or the Company or to cease operations, or have no realistic alternative but to do so.# Auditor's Responsibilities

Our objectives are to obtain reasonable assurance about whether the parent and consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue our auditor’s report. Reasonable assurance is a high level of assurance, but does not guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of the parent and consolidated financial statements.

A fuller description of our responsibilities is provided on the FRC’s website at www.frc.org.uk/auditorsresponsibilities.

The Purpose of This Report and Restrictions on Its Use by Persons Other Than the Company’s Members as a Body

This report is made solely to the Company’s members, as a body, in accordance with chapter 3 of part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the Company’s members those matters we are required to state to them in an auditor’s report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company and its members, as a body, for our audit work, for this report, or for the opinions we have formed.

Annual Report 2024

1. General Information

Company Information

HydrogenOne Capital Growth plc (the “Company” or “Parent”) was incorporated in England and Wales on 16 April 2021 with registered number 13340859 as a public company limited by shares and is an investment company within the terms of Section 833 of the Companies Act 2006 (the “Act”). The Company is listed and began trading on the Main Market of the London Stock Exchange and was admitted to the premium segment of the Official List on 30 July 2021 (the “IPO”).

The Company has applied for and been accepted as an approved investment trust under sections 1158 and 1159 of the Corporation Tax Act 2010 and Part 2 Chapter 1 of Statutory Instrument 2011/2999.

FundRock Management Company (Guernsey) Limited acts as the Company’s Alternative Investment Fund Manager (“AIFM”). Apex Listed Companies Services (UK) Limited (the “Company Secretary and Administrator”) provides administrative and company secretarial services to the Company. The Company’s Investment Adviser is HydrogenOne Capital LLP.

The Company’s registered office is 4th Floor, 140 Aldersgate Street, London, EC1A 4HY.

Investment Objective

The Company’s investment objective is to deliver an attractive level of capital growth by investing, directly or indirectly, in a diversified portfolio of hydrogen and complementary hydrogen focused assets whilst integrating core environmental, social and governance (“ESG”) principles into its decision making and ownership process.

Company Structure

The Company makes its investment in unquoted Hydrogen Assets (“Private Hydrogen Assets”) through HydrogenOne Capital Growth Investments (1) LP (the “Limited Partnership”), in which the Company is the sole Limited Partner. The Limited Partnership is registered as a private fund limited partnership in England and Wales under the Limited Partnerships Act 1907 with registered number LP021814. The Limited Partnership has been established pursuant to a Limited Partnership Agreement dated 5 July 2021 as amended and restated on 26 November 2021 (the “Limited Partnership Agreement”) in order to make investments pursuant to the investment policy of the Limited Partnership. The Limited Partnership’s investment policy and restrictions are consistent with the Company’s investment policy and restrictions for Private Hydrogen Assets.

The General Partner of the Limited Partnership is HydrogenOne Capital Growth (GP) Limited (the “General Partner”), a wholly owned subsidiary of the Company. The General Partner was incorporated in England and Wales on 19 May 2021 with registered number 13407844. The General Partner undertakes the responsibility for the management, operation and administration of the business and affairs of the Limited Partnership.

The General Partner’s Profit Share for each accounting period shall be an amount equal to 1.5% per annum of the prevailing NAV of the Limited Partnership, which shall be allocated to the General Partner as a first charge on the profits of the Limited Partnership.# For so long as the Company is the sole Limited Partner, the General Partner’s Profit Share shall be allocated and distributed to the Company rather than the General Partner. The carried interest partner of the Limited Partnership is HydrogenOne Capital Growth (Carried Interest) LP (the “Carried Interest Partner”) which, in certain circumstances, will receive carried interest on the realisation of Private Hydrogen Assets by the Limited Partnership. The Carried Interest Partner has been set up for the benefit of the principals of the Investment Adviser. Further details of the carried interest fees payable to the Carried Interest Partner are given in Note 6 to the Financial Statements. During the year, a new wholly owned subsidiary of the Company, HydrogenOne Capital Growth Investments (1A) LP (“Limited Partnership 1A”), was incorporated pursuant to the sale of GEN2 Energy AS. Following the completion of the sale during the year, the Company withdrew as a limited partner of Limited Partnership 1A. The General Partner of Limited Partnership 1A is HydrogenOne Capital Growth Investments (1A) GP LLP (the “General Partner 1A”), a wholly owned subsidiary of the Company. The General Partner 1A was incorporated in England and Wales on 3 June 2024 with registered number OC452544. The General Partner 1A shares the responsibility for the management, operation and administration of the business and affairs of Limited Partnership 1A with a third party. General Partner 1A is entitled to receive 1% of the proceeds received by Limited Partnership 1A (if any) .

Private Hydrogen Assets

The Company invests via the Limited Partnership in Private Hydrogen Assets, which may be operational companies or hydrogen projects. Investments are mainly in the form of equity, although investments may be made by way of debt and/or convertible securities. The Company may acquire a mix of controlling and non-controlling interests in Private Hydrogen Assets, however the Company invests principally in non-controlling positions (with suitable minority protection rights to, inter alia, ensure that the Private Hydrogen Assets are operated and managed in a manner that is consistent with the Company’s investment policy).

HydrogenOne Capital Growth plc Annual Report 2024

Company Overview
Strategic Report
Governance
Financial statements
Other information

The Company acquires Private Hydrogen Assets via the Limited Partnership, directly or by way of holdings in special purpose vehicles or intermediate holding entities (including successor limited partnerships established on substantially the same terms as the Limited Partnership) or, if the Company is considered a ‘feeder fund’ under the Listing Rules, other undertakings advised by the Investment Adviser and, in such circumstances, the investment policy and restrictions will also be applied on a look-through basis and such undertaking(s) will also be managed in accordance with the Company’s investment policy.

Listed Hydrogen Assets

The Company also invests directly in quoted or traded Hydrogen Assets, which are predominantly equity securities but may also be corporate debt and/or other financial instruments (“Listed Hydrogen Assets”). The Company has the ability to invest in Listed Hydrogen Assets in any market or country with a market capitalisation (at the time of investment) of at least US$100 million. The Company’s approach is to be a long-term investor and will not ordinarily adopt short-term trading strategies.

Liquidity reserve

During the initial Private Hydrogen Asset investment period after a capital raise and/or a realisation of a Private Hydrogen Asset, the Company intends to allocate the relevant net proceeds of such capital raise/realisation to cash (in accordance with the Company’s cash management policy) and/or additional Listed Hydrogen Assets and related businesses pending subsequent investment in Private Hydrogen Assets (the ‘’Liquidity Reserve’’). The Company anticipates holding cash to cover the near-term capital requirements of the pipeline of Private Hydrogen Assets and in periods of high market volatility.

2. Basis of preparation

The principal accounting policies are set out below:

Reporting entity

These Parent and Consolidated Financial Statements (the “Financial Statements”) present the results of both the Parent; and the Parent, the General Partner and General Partner 1A (together referred to as the “Group”). At 31 December 2024, the statement of financial position of the General Partner and General Partner 1A consisted of issued share capital and corresponding share capital receivable in the amount of £1 (2023: £1) and £10 respectively. The General Partners had no income, expenditure or cash flows for the period. Due to the immaterial balances of the General Partners there is no material difference between the results of the Parent and the results of the Group. As a result, the Financial Statements as presented represent both the Parent and the Group’s financial position, performance, and cash flows.

Basis of accounting

The Financial Statements have been prepared in accordance with UK-adopted international accounting standards (“IFRS”) and the applicable legal requirements of the Companies Act 2006. The Financial Statements have also been prepared as far as is relevant and applicable to the Company and Group in accordance with the Statement of Recommended Practice (‘SORP’) issued by the Association of Investment Companies (“AIC”) in July 2022. The Financial Statements are prepared on the historical cost basis, except for the revaluation of financial instruments measured at fair value through profit or loss. Fair value is the price that would be received on sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, regardless of whether that price is directly observable or estimated using another valuation technique. In estimating the fair value of an asset or liability, the Company and Group take into account the characteristics of the asset or liability if market participants would take those characteristics into account when pricing the asset or liability at the measurement date. Fair value for measurement and/or disclosure purposes in these Financial Statements is determined on such a basis. The Financial Statements are presented in Pounds Sterling because that is the currency of the primary economic environment in which the Company and Group operate. The principal accounting policies adopted are set out below. These policies are consistently applied.

HydrogenOne Capital Growth plc Annual Report 2024

Accounting for subsidiaries

The Board of Directors has determined that the Company has all the elements of control as prescribed by IFRS 10 in relation to:

  1. the Limited Partnership; as the Company is the sole limited partner in the Limited Partnership (100% of the Limited Partnership’s commitments are held by the Company), is exposed to and has rights to the returns of the Limited Partnership, and has the ability through its control of the General Partner to affect the amount of its returns from the Limited Partnership; and
  2. the General Partner and the General Partner 1A (together the ‘General Partners’); as the Company wholly owns the General Partners, is exposed to and has rights to the returns of the General Partners and has the ability through its control of the General Partners’ activities to affect the amount of its returns from the General Partners.

The Investment entities exemption requires that an investment entity that has determined that it is a parent under IFRS 10 shall not consolidate certain of its subsidiaries; instead, it is required to measure its investment in these subsidiaries at fair value through profit or loss in accordance with IFRS 9. The criteria which define an investment entity are as follows:

(i) the company obtains funds from one or more investors for the purpose of providing those investors with investment management services;
(ii) the company commits to its investors that its business purpose is to invest funds solely for returns from capital appreciation, investment income, or both; and
(iii) the company measures and evaluates the performance of substantially all of its investments on a fair value basis.

The Company is an investment company, providing investors exposure to a diversified portfolio of hydrogen and complementary hydrogen focussed assets that are managed for investment purposes. The investments were made in line with the stated objective of the Company to deliver an attractive level of capital growth in accordance with the strategy that has been set by the Directors. In assessing whether the Company meets the definition of an investment entity set out in IFRS 10 the Directors’ note that:

(i) the Company has multiple investors with shares issued publicly on the London Stock Exchange and obtains funds from a diverse group of shareholders who would otherwise not have access individually to investing in hydrogen focussed assets;
(ii) the Company’s purpose is to invest funds for capital appreciation but with potential for some investment income. The Limited Partnership has a ten-year life however the underlying assets have minimal residual value because they do not have unlimited lives, are not to be held indefinitely and have appropriate exit strategies in place; and
(iii) the Company measures and evaluates the performance of all of its investments on a fair value basis which is the most relevant for investors in the Company. The Directors use fair value information as a primary measurement to evaluate the performance of all of the investments and in decision making. The Directors assess each new investment carefully to determine whether the Company as a whole continues to meet the definition of an investment entity.# Notes to the parent and consolidated financial statements

Going concern

The Company and Group had at 31 December 2024 unrestricted cash of £3.1 million (2023: £4.6 million). At the date of approval of these Financial Statements, the Company and Group had cash resources of £2.4 million and annual expenses are estimated to be £3.1 million. Based on the current cash position and the estimated expenses of the Company and the Group over the next twelve months, the Board has determined that there will be a shortfall of cash without any further action. The Directors have concluded that this represents a material uncertainty that may cast significant doubt on the Company and Group’s ability to continue as a going concern. The Company’s strategy has been set to address this. Further cost savings are anticipated in 2025. The Company continues to seek both secondary sales of parts of its portfolio, and full exits from portfolio companies. The Company continues to monitor opportunities for a fresh equity raise, although the discount of the share price to the NAV may prevent this. In addition, the Company is engaged with lenders to potentially access debt for the fund. The Board and the Investment Adviser are considering a wide range of options, with urgency, to deliver shareholder value, with confidential discussions underway with third parties. The Directors acknowledge that there are risks attached to each of these plans. For example all the cost savings identified may not be achieved and may be offset by inflationary cost rises elsewhere. However the Board and the Investment Adviser are confident a secondary sale of part of one of the investments in the portfolio can be achieved based on the Company’s prior experience of realising Gen2 Energy and ongoing secondary transactions in the Private Hydrogen Assets. As such the Board believe the plans are achievable, whether together or in isolation and will cover the cash shortfall. The Directors also recognise that the continuation of the Company is subject to the approval of shareholders at the Annual General Meeting (“AGM”) in 2026, and every fifth AGM thereafter. The Board has considered the long-term prospects of the Company. The Board notes the current liquidity position of the Company as described above, and also the high discount to NAV of the current share price, and recognises this increases the risk that the continuation vote will not be passed. However the Board believe the actions described to improve liquidity will put the Company in a stronger position over the coming year, and the performance of the remaining Private Hydrogen Assets and the expected growth in the clean energy and hydrogen sectors mean the prospects for the Company remain positive and this will be reflected in improved performance of the Company over the next twelve months. In the event that continuation vote is not passed, the Directors are required to draw up proposals for shareholders’ approval for the reconstruction or reorganisation of the Company, which would require a special resolution of the shareholders. Following the declaration of the Company’s Net Asset Value as at the 31 December 2024, on 5 February 2025, the Company’s share price was 21.95p representing a 75.7% discount to the Net Asset Value (31 December 2024: discount of 76.0%). Based on the above, the Directors continue to adopt the going concern basis in preparing these Financial Statements. Accordingly, these Financial Statements do not include any adjustments to the carrying amount or classification of assets and liabilities that would result if the Company and Group were unable to continue as a going concern.

Critical accounting judgements, estimates and assumptions

The preparation of Financial Statements in accordance with IFRS requires the Directors to make judgements, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Financial Statements and the reported amounts of income and expense during the period. Actual results could differ from those estimates. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised if the revision only affects that period or in the period and future periods if the revision affects both current and future periods.

Judgements

Investment entity

In accordance with the Investment Entities exemption contained in IFRS 10, the Board has determined that the Company satisfies the criteria to be regarded as an investment entity and that the Company provides investment related services and, as a result, measures its investment in the Limited Partnership at fair value. The Limited Partnership serves as an asset holding entity and does not provide investment-related services. Therefore, when the Limited Partnership is assessed based on the overall structure as a means of carrying out the Company’s activities, the Board of Directors has determined that the Limited Partnership meets the definition of an investment entity. Accordingly, the Company is required under IFRS 10 to hold its investment in the Limited Partnership at fair value through the Statement of Comprehensive Income rather than consolidate them. The General Partners provide investment related services to their respective limited partnership on behalf of the Company. IFRS 10 requires subsidiaries that provide services that relate to the investment entity’s investment activities to be consolidated. Accordingly, the Board of Directors have determined that the Company is required under IFRS 10 to consolidate the results of the General Partners. As described in the Reporting Entity section, the Financial Statements as presented represent both the Parent’s and the Group’s financial position, performance and cash flows. These conclusions involved a degree of judgement and assessment as to whether the Company, the Limited Partnership and the General Partners met the criteria outlined in the accounting standards.

Going Concern

As noted earlier in this note 2, the Board recognises the current financial situation of the Company and notes the operational resources available to the Company and Group are not currently adequate to cover the expenses of the Company for at least twelve months from the date of approval of these Financial Statements. The Board has reviewed the actions being taken to address the current cash position and have concluded that the criteria for preparing the Financial Statements on a going concern basis have been met.

Estimates

Investment valuations

The key estimate in the Financial Statements is the determination of the fair value of the Private Hydrogen Assets, held by the Limited Partnership, by the Investment Adviser for consideration by the Directors. This estimate is key as it significantly impacts the valuation of the Limited Partnership at the year end. The fair valuation process involves estimation using subjective inputs that are unobservable (for which market data is unavailable). The key inputs considered in the valuation are described in note 15.

New standards, interpretations and amendments adopted from 1 January 2024

Effective in the current financial year
The Board have assessed those new standards, interpretations, and/or amendments which became effective during the financial year under review and concluded they have no material impact to the Company.

New standards and amendments issued but not yet effective
The relevant new and amended standards and interpretations that are issued, but not yet effective, up to the date of issuance of the financial statements are disclosed below.# Amendments to IAS 21 - Lack of Exchangeability (effective for annual periods beginning on or after 1 January 2025)

Amendments to the Classification and Measurement of Financial Instruments

Amendments to IFRS 9 and IFRS 7 (effective for annual periods beginning on or after 1 January 2026)

IFRS 18 Presentation and Disclosure in Financial Statements (effective for annual periods beginning on or after 1 January 2027)

IFRS 18 will replace IAS 1 Presentation of Financial Statements and introduces the following key requirements.
* Entities are required to classify all income and expenses into five categories in the statement of comprehensive income, namely operating, investing, financing, discontinued operations and income tax categories. Entities are also required to present a newly-defined operating profit subtotal. Entities’ net profit will not change as a result of applying IFRS 18.
* Management-defined performance measures (“MPMs”) are disclosed in a single note in the financial statements.
* Enhanced guidance is provided on how to group information in the financial statements.

In addition, all entities are required to use the operating profit subtotal as the starting point for the statement of cash flows when presenting operating cash flows under the indirect method.

The Board have assessed new but not yet effective standards applicable to the Company and have concluded that, with the exception of IFRS 18, they will not have a material impact to the Company. The Company is still in the process of assessing the impact of IFRS 18, particularly with respect to the structure of the Company’s statement of comprehensive income, the statement of cash flows and the additional disclosures required for MPMs. The Company is also assessing the impact on how information is grouped in the financial statements, including for items currently labeled as “other”.

3. Material accounting policies

(a) Financial instruments

Financial assets – Classification, recognition, derecognition and measurement

The Company and Group’s financial assets principally comprise of: investments held at fair value through profit or loss (Listed Hydrogen Assets and the Limited Partnership); and trade and other receivables, which are initially recognised at fair value and subsequently measured at amortised cost.

Financial assets are recognised in the Statement of Financial Position when the Company or Group become a party to the contractual provisions of the instrument. Transaction costs that are directly attributable to the acquisition or issue of financial assets (other than financial assets at fair value through profit or loss) are added to or deducted from the fair value of the financial assets, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets at fair value through profit or loss are recognised immediately in profit or loss.

Notes to the parent and consolidated financial statements

FUTURE FUEL. NOW 79 HydrogenOne Capital Growth plc Annual Report 2024

Company Overview Strategic Report Governance Financial statements Other information

Subsequent to initial recognition, financial assets at fair value through profit or loss are measured at fair value. Gains and losses resulting from the movement in fair value are recognised in the Statement of Comprehensive Income at each valuation point within ‘gains/(losses) on investments’.

Financial assets are derecognised when the rights to receive cash flows from the investments have expired or the Company or Group have transferred substantially all risks and rewards of ownership. For Listed Hydrogen Assets, realised (losses)/ gains are calculated using the average cost method. Distributions received from the Limited Partnership are treated as a return of capital and reduce the cost basis of the Company’s investment in the Limited Partnership. If the Limited Partnership’s cost basis if reduced to nil, any subsequent distributions will be recorded as realised gains

Financial liabilities – Classification, recognition, derecognition and measurement

The Company and Group’s financial liabilities include trade and other payables and other short term monetary liabilities which are initially recognised at fair value and subsequently measured at amortised cost.

Financial liabilities are recognised in the Statement of Financial Position when the Company or Group become a party to the contractual provisions of the instrument. Transaction costs that are directly attributable to the acquisition or issue of financial liabilities (other than financial liabilities at fair value through profit or loss) are added to or deducted from the fair value of the financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial liabilities at fair value through profit or loss are recognised immediately in profit or loss. Financial liabilities are subsequently measured at amortised cost.

A financial liability (in whole or in part) is derecognised when the Company or Group have extinguished the contractual obligations, it expires or is cancelled.

Valuation of Listed Hydrogen Assets

Upon initial recognition Listed Hydrogen Assets are classified by the Company and Group ‘at fair value through profit or loss’. They are accounted for on the date they are traded and are included initially at fair value which is taken to be their cost. Subsequently they are valued at fair value, which is the bid market price, or if bid price is unavailable, last traded price on the relevant exchange.

Valuation of the Limited Partnership

The Company may make investments in Private Hydrogen Assets directly, via the Limited Partnership and/or by way of holdings in special purpose vehicles or intermediate holding entities. Currently, all the Company’s Private Hydrogen Assets are held via the Limited Partnership.

The Company and Group has determined that the fair value of the Limited Partnership is the Limited Partnership’s Net Asset Value (“NAV”). The NAV of the Limited Partnership is prepared in accordance with accounting policies that are consistent with IFRS and consists of the fair value of its Private Hydrogen Assets, and the carrying value of its assets and liabilities.

The Investment Adviser values the Private Hydrogen Assets according to IPEV Guidelines. The valuation techniques available under IPEV Guidelines are set out below and are followed by an explanation of how they are applied to the Private Hydrogen Assets:
* Discounted cash flows (“DCF”);
* Price of recent investment;
* Multiples;
* Industry Valuation Benchmarks;
* Available Market Prices; and
* Net Assets

The nature of the Private Hydrogen Assets will influence the valuation technique applied. The valuation approach recognises that, as stated in the IPEV Guidelines, the price of a recent investment, if resulting from an orderly transaction, generally represents fair value as at the transaction date and may be an appropriate starting point for estimating fair value at subsequent measurement dates. Consideration is given to the facts and circumstances as at the subsequent measurement date such as changes in the market or performance of the investee company including whether maintainable revenues and/ or earnings have been established. Milestone analysis is used, where appropriate, to incorporate the operational progress of the investee company into the valuation. As a result, various techniques may be employed to derive the valuations. However, an absence of relevant industry peers may preclude the application of the industry valuation benchmarks technique and an absence of observable prices may preclude the available market prices approach. All valuations are calibrated and are cross-checked for reasonableness by employing relevant alternative techniques.

Private Hydrogen Assets, which are operational companies, are valued using either the price of recent investment; the DCF method; or a combination of the DCF method and the price of recent investment. The valuations are weighted towards the DCF method based on the time since the price of recent investment until the full DCF valuation is applied (typically the valuations

FUTURE FUEL. NOW 80 HydrogenOne Capital Growth plc Annual Report 2024

are tapered from the price of recent investment to the full DCF valuation over four calendar quarters after the price of recent investment). The impact of this weighted approach is that there will be either an effective discount or a premium to the full DCF valuation over the tapering period. The valuations derived from this approach have been assessed for reasonableness against relevant market comparables, where available, and calibrated against specific milestones for indications of positive or negative performance which may impact valuations. Where negative performance indicates that the valuation of a Private Hydrogen Asset may have deteriorated substantially then alternative valuation approaches may be incorporated into the valuation model that reflect reasonable possible outcomes, such as net assets and indicative offers, and a probability weighting is applied to each.

Private Hydrogen Assets, which are hydrogen project SPVs, are valued based on the underlying project’s stage of completion:
* prior to commercial operation date, hydrogen project SPVs are valued using a risk adjusted DCF method;
* post commercial operation date, hydrogen project SPVs are valued in the same way as Private Hydrogen Assets, which are operational companies, as described above; and
* project development loans advanced directly by the Limited Partnership to a project during the project development phase are held at cost plus accrued interest (deemed to approximate fair value), and are reviewed at each valuation date for any indicators that this approach may no longer be representative of fair value.# NOTES TO THE PARENT AND CONSOLIDATED FINANCIAL STATEMENTS

(a) Valuation of investments In a DCF valuation, the fair value represents the present value of the investment’s expected future cash flows, based on appropriate assumptions for revenues and costs, and suitable cost of capital assumptions. Judgement is applied in arriving at appropriate discount rates, based on the knowledge of the market, taking into account market intelligence gained from bidding activities, discussions with financial advisers, consultants, accountants and lawyers and publicly available information. A range of sources are reviewed in determining the underlying assumptions to apply in a DCF valuation used in calculating the fair value of a Private Hydrogen Asset. These sources include but are not limited to:
• macroeconomic projections adopted by the market as disclosed in publicly available resources;
• macroeconomic forecasts provided by expert third party economic advisers;
• discount rates publicly disclosed in the global renewables sector;
• discount rates applicable to comparable infrastructure asset classes, which may be procured from public sources or independent third-party expert advisers;
• discount rates publicly disclosed for comparable market transactions of similar assets; and
• capital asset pricing model outputs and implied risk premia over relevant risk-free rates.
Where available, assumptions are based on observable market and technical data.

Items included in the Financial Statements are measured using the currency of the primary economic environment in which the entity operates, the functional currency. The Financial Statements are presented in Pounds Sterling which is the Company and Group’s functional and presentation currency.

Transactions and balances
Foreign currency transactions are translated into Pounds Sterling using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the Statement of Comprehensive Income.

(c) Income
Dividend income has been accounted for on an ex-dividend basis or when the right to the income is established. Investment interest income for the year is recognised in the Statement of Comprehensive Income using effective interest method calculation. Bank interest income is recognised for the year in the Statement of Comprehensive income on a receipts basis. Special dividends are credited to capital or revenue in the Statement of Comprehensive Income, according to the circumstances surrounding the payment of the dividend. Overseas dividends are included gross of withholding tax recoverable.

(d) Dividend payable
Interim dividends are recognised when the Company pays the dividend. Final dividends are recognised in the period in which they are approved by the shareholders.

(e) Expenses
All expenses are accounted for on an accruals basis. Expenses directly related to the acquisition or disposal of an investment (transaction costs) are taken to the Statement of Comprehensive Income as a capital item. All other expenses, including Investment Adviser fees, are taken to the Statement of Comprehensive Income as a revenue item.

HydrogenOne Capital Growth plc Annual Report 2024

(f) Taxation
The tax expense represents the sum of the tax currently payable and deferred tax. The tax currently payable is based on the taxable profit for the period. Taxable profit differs from net profit as reported in the Statement of Comprehensive Income because it excludes items of income or expenses that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The Company’s liability for current tax is calculated using tax rates that were applicable at the financial reporting date. Where expenses are allocated between capital and revenue any tax relief in respect of the expenses is allocated between capital and revenue returns on the marginal basis using the Company’s effective rate of corporation taxation for the relevant accounting period. Deferred taxation is recognised in respect of all timing differences that have originated but not reversed at the financial reporting date, where transactions or events that result in an obligation to pay more tax in the future or right to pay less tax in the future have occurred at the financial reporting date. This is subject to deferred tax assets only being recognised if it is considered more likely than not that there will be suitable profits from which the future reversal of the timing differences can be deducted. Deferred tax assets and liabilities are measured at the rates applicable to the legal jurisdictions in which they arise. Since the General Partners do not have any income or expenditure in the period, the Group tax position is the same as the Company tax position.

(g) Segmental reporting
The Board has considered the requirements of IFRS 8 – ‘Operating Segments’. The Company has entered into an Investment Advisory Agreement with the Investment Adviser under which the Investment Adviser is responsible for the management of the Company’s investment portfolio, subject to the overall supervision of the Board of Directors. Subject to its terms and conditions, the Investment Advisory Agreement requires the Investment Adviser to manage the Company’s investment portfolio in accordance with the Company’s investment guidelines as in effect from time to time, including the authority to purchase and sell investments and to carry out other actions as appropriate to give effect thereto. However, the Board retains full responsibility to ensure that the Investment Adviser adheres to its mandate. Moreover, the Board is fully responsible for the appointment and/or removal of the Investment Adviser. Accordingly, the Board is deemed to be the ‘Chief Operating Decision Maker’ of the Company. The Directors are of the opinion that the Company is engaged in a single segment of business being investment into the hydrogen focused investments. Segment information is measured on the same basis as that used in the preparation of the Company’s Financial Statements.

(h) Cash and cash equivalents
Cash comprises cash and demand deposits. Cash equivalents, include bank overdrafts, and short-term, highly liquid investments that are readily convertible to known amounts of cash, are subject to insignificant risks of changes in value, and are held for the purpose of meeting short-term cash commitments rather than for investment or other purposes.

(i) Nature and purpose of equity and reserves:
Share capital represents the 1p nominal value of the issued share capital. The share premium account arose from the net proceeds of new shares issued. Costs directly attributable to the issue of new shares are charged against the value of the ordinary share premium. The capital reserve reflects any:
• gains or losses on the disposal of investments;
• exchange movements of a capital nature;
• the increases and decreases in the fair value of investments which have been recognised in the capital column of the Statement of Comprehensive Income; and
• expenses which are capital in nature.
The revenue reserve reflects all income and expenditure recognised in the revenue column of the Statement of Comprehensive Income and is distributable by way of dividend. The Company’s distributable reserves consist of the revenue reserve and the capital reserve. However any gains in the fair value of investments that are not readily convertible to cash are treated as unrealised gains in the capital reserve and are non-distributable. Ordinary Shares are classified as equity.

Under IFRS 13 ‘Fair Value Measurement’, an entity is required to classify investments using a fair value hierarchy that reflects the significance of the inputs used in making the measurement decision. The following shows the analysis of financial assets recognised at fair value based on:
Level 1 The unadjusted quoted price in an active market for identical assets or liabilities that the entity can access at the measurement date.
Level 2 Inputs other than quoted prices included within Level 1 that are observable (i.e.# Notes to the parent and consolidated financial statements

Level 3 Inputs are unobservable (i.e. for which market data is unavailable) for the asset or liability. Transfers between levels of the fair value hierarchy are recognised as at the end of the reporting period during which the change has occurred. There have been no transfers between levels during the year ended 31 December 2024 (2023: no transfers).

*In deriving the fair value of NanoSUN a probability weighted approach was applied whereby a valuation for the investment was derived from each technique (DCF, indicative offers and assets), each of which represented management’s assessment of the fair value for the investment in the reasonable possible scenarios that may have transpired, as of the valuation date. A percentage likelihood (aggregating to 100% across each of the three techniques) was then applied to each of these valuations, which represented management’s view of the probability of each scenario transpiring, as of the valuation date. The range of inputs disclosed represent the lowest and highest discreet percentages applied to the three scenarios.

The following table shows the Directors best estimate of the sensitivity of the Level 3 Private Hydrogen Assets to changes in the principle unobservable input, with all other variables held constant.

The European Central Bank (‘ECB’) and the Bank of England (‘BOE’) base rates at 31 December 2024 were 3.15% and 4.75% respectively. We anticipate that the base rates will ease and fall (based on independent research) reaching 2.00% for ECB and 4.00% for BOE by end of 2025. Since long term gilt yields already factor in long term forecasts, we have performed sensitivities of +/- 1% on the discount rate assumptions for any shock events.

At 31 December 2023, the ECB and the BOE base rates were 4.5% and 5.25% respectively. We anticipated that the terminal base rate would ease and fall (based on independent research) reaching 2.5% for ECB and 3.0% for BOE and as such, performed sensitivities of +/- 1% on the discount rate assumptions.

For the year ended 31 December 2023, the NanoSUN Limited valuation was weighted between DCF, indicative offers and Net assets based on the expected likelihood of each scenario occurring. We applied a sensitivity of +/- 10% weighting to each scenario, with the movement being shared equally with the remaining two scenarios, as this was deemed to be a reasonable possible shift in the scenario weightings as of the valuation date.

For those investments that have been fair valued using the price of a recent investment based on unadjusted third-party pricing information, the Company is not required to disclose any quantitative information regarding the unobservable inputs as they have not been developed by the Company and are not reasonably available to the Company.

Investment Adviser fee

The Company has entered into an Investment Adviser Agreement dated 5 July 2021 between the Company, the AIFM and the Investment Adviser (the “Investment Adviser Agreement”), pursuant to which the Investment Adviser has been given responsibility for investment advisory services in respect of any Private Hydrogen Assets the Company invests in directly and the Listed Hydrogen Assets (including Listed Hydrogen Assets forming part of the Liquidity Reserve and uninvested cash) in accordance with the Company’s investment policy, subject to the overall control and supervision of the AIFM.

Under the Investment Adviser Agreement, the Investment Adviser receives from the Company, quarterly in advance, an advisory fee equal to:
i. 1.0% of the Net Asset Value per annum of the Listed Hydrogen Assets up to £100 million:
ii. 0.8% of the Net Asset Value per annum of the Listed Hydrogen Assets from £100 million (save that the Investment Adviser has agreed to reduce this fee to 0.5% in respect of the Liquidity Reserve pending their investment in Private Hydrogen Assets for 18 months following Admission to 30 January 2023);
iii. 1.5% of the Net Asset Value per annum of any Private Hydrogen Assets held by the Company directly (i.e. not held by the Limited Partnership or any other undertaking advised by the Investment Adviser where the Investment Adviser is receiving a separate advisory fee); and
iv. for so long as the Company is not considered a ‘feeder fund’ for the purposes of the Listing Rules, 1.5% per annum of the Net Asset Value of the Private Hydrogen Assets held by the Limited Partnership.

FUTURE FUEL. NOW 86

HydrogenOne Capital Growth plc Annual Report 2024The Limited Partnership has entered into a Limited Partnership Investment Adviser Agreement dated 5 July 2021 (the “Limited Partnership Investment Adviser Agreement”) between the General Partner (in its capacity as general partner of the Limited Partnership), the AIFM and the Investment Adviser, pursuant to which the Investment Adviser has been given responsibility for investment advisory services in respect of the Private Hydrogen Assets in accordance with the investment policy of the Limited Partnership, subject to the overall control and supervision of the AIFM.

Under the Limited Partnership Investment Adviser Agreement, the Investment Adviser, if the Company was considered a ‘feeder fund’ for the purposes of the Listing Rules by virtue of additional investors co-investing via the Limited Partnership in the future, shall receive from the Limited Partnership an advisory fee equal to 1.5% per annum of the Net Asset Value of the Private Hydrogen Assets held by the Limited Partnership, payable quarterly in advance. Advisory fees paid or payable by the Limited Partnership are reflected through the NAV of the Limited Partnership.

No performance fee is paid or payable to the Investment Adviser under either the Investment Adviser Agreement or the Limited Partnership Investment Adviser Agreement but the principals of the Investment Adviser are, subject to certain performance conditions being met, entitled to carried interest fees from the Limited Partnership. Refer to ‘Carried Interest Partner Fees’ section below.

Carried Interest Partner Fees

Pursuant to the terms of the Limited Partnership Agreement dated 5 July 2021 as amended and restated on 26 November 2021 (the “Limited Partnership Agreement”), the Carried Interest Partner is, subject to the limited partners of the Limited Partnership receiving an aggregate annualised 8% realised return (i.e. the Company and, in due course, any additional co-investors), entitled to a carried interest fee in respect of the performance of the Private Hydrogen Assets.

Subject to certain exceptions, the Carried Interest Partner will receive, in aggregate, 15% of the net realised cash profits from the Private Hydrogen Assets held by the Limited Partnership once the limited partners of the Limited Partnership (i.e. the Company and, in due course, any additional co-investors) have received an aggregate annualised 8% realised return. This return is subject to a ‘catch-up’ provision in the Carried Interest Partner’s favour.

Any realised or unrealised carried interest fee paid or payable to the Carried Interest Partner is reflected through the NAV of the Limited Partnership.

During the period no carried interest fees (31 December 2023: £403,343) were accrued as payable to the Carried Interest Partner.

20% of any carried interest received (net of tax) will be used by the principals of the Investment Adviser to acquire Ordinary Shares in the market. Any such acquired shares will be subject to a 12-month lock-up from the date of purchase.

General Partner’s priority profit share

Under the Limited Partnership Agreement, the General Partner of the Limited Partnership shall be entitled to a General Partner’s Profit Share (“GPS”). The GPS for each accounting period shall be an amount equal to 1.5% of the prevailing NAV of the Limited Partnership. For so long as the Company is the sole limited partner of the Limited Partnership, the GPS shall be distributed to the Company rather than the General Partner. The Company is currently the sole limited partner of the Limited Partnership.

Therefore, under the Investment Adviser Agreement, the investment adviser fee in relation to the Private Hydrogen Assets held by the Limited Partnership is settled by the Company which for the year totalled £1,957,439 (31 December 2023: £1,723,369).

During the year the Limited Partnership did not call any GPS from the Company as the net effect of the calling and distributing GPS from/to the Company is £nil (31 December 2023: £nil).

The General Partner of Limited Partnership 1A is entitled to receive 1% of the proceeds received by Limited Partnership 1A (if any). No GPS was received from Limited partnership 1A during the year.

The Company is not liable to tax on capital gains due to its status as an investment trust.

The Company and Group has an unrecognised deferred tax asset of £1,246,000 (2023: £963,000) as a result of excess management expenses of £5,103,000 (2023: 3,853,000), based on the long term prospective corporation tax rate of 25%. This asset has accumulated because deductible expenses exceeded taxable income for the year ended 31 December 2024 and prior periods. No asset has been recognised in the Financial Statements because, given the composition of the Company and Group’s portfolio, it is not likely that this asset will be utilised in the foreseeable future.

Such Ordinary Shares may be subsequently cancelled or sold for cash. No Ordinary Shares have been repurchased during the year therefore there were no Treasury shares at the end of the year.

Each Ordinary Share held entitles the holder to one vote. All shares carry equal voting rights and there are no restrictions on those voting rights.

Risk Management Policies and Procedures

The Board of Directors has overall responsibility for the establishment and oversight of the Company and Group’s risk management framework. The risk management policies are established to identify and analyse the risks faced by the Company and Group, to set appropriate risk limits and controls and to monitor risks and adherence to limits. Risk management policies are reviewed regularly to reflect changes in market conditions and the Company and Group’s activities. The Investment Adviser, AIFM and the Administrator report to the Board on a quarterly basis and provide information to the Board which allows it to monitor and manage financial risks relating to its operations. The Company and Group’s activities expose it to a variety of financial risks: market risk (including currency risk, interest rate risk and price risk), credit risk, liquidity risk and operational risk. These risks are monitored by the AIFM. Below is a non-exhaustive summary of the risks that the Company and Group are exposed to as a result of its use of financial instruments:

The objectives, policies and processes for managing the risks, and the methods used to measure the risks, are set out below:

Market Risks

(i) Currency risk

Foreign currency risk is defined as the risk that the fair values of future cashflows will fluctuate because of changes in foreign exchange rates. The financial assets and liabilities are predominantly denominated in Pounds Sterling and substantially all revenues and expenses are in Pounds Sterling. As at the 31 December 2024 and 31 December 2023, the Company and Group had the following currency exposures, all of which are included in the Statement of Financial Position at fair value based on the exchanges rates at the year end.

31 December 2024 31 December 2023
Other assets Other assets
Currency Investments Cash & liabilities Total Investments Cash & liabilities Total
£’000 £’000 £’000 £’000 £’000 £’000 £’000
Danish Krone 180
Euro 806
Korean Won 501
Norwegian Krone 259
Swedish Krona 3
US Dollar 213
1,962

The Company and Group mitigate the risk of loss due to exposure to a single currency by way of diversification of the portfolio.The Limited Partnership’s non-Pound Sterling denominated assets may have currency exposure hedged by Forward Exchange Contracts so that impact from currency exchange rate movements would be mitigated. As at 31 December 2024, the Limited Partnership’s non-Pound denominated investments amounted to £67,241,000 (2023: £84,586,000) This increases foreign currency risk and may increase volatility of the Company and Group’s net asset value. Notwithstanding the currency exposure of the Limited Partnership’s non-Pound Sterling denominated investments as explained in the preceding paragraph, at 31 December 2024 an exchange rate movement of +/-5% against Pounds Sterling, which is a reasonable approximation of possible changes based on observed volatility during the year, would have increased or decreased net assets and total return by £Nil (2023: £98,100).

(ii) Interest rate risk

The Company and Group’s interest rate risk on interest bearing financial assets is limited to interest earned on cash balances. At the year end, the Company and Group had cash balances of £3,100,000 (2023: £4,626,000). An increase in interest rates of 2.0%, which is reasonable based upon changes in interest rates observed in the year, would impact the profit or loss and net assets of the Company and Group positively by £62,000, with a decrease of 2.0% having an equal and opposite effect (2023: an increase or decrease of 2% would have had a positive or negative affect of £92,520) .

The Company and Group’s interest and non-interest bearing assets and liabilities as at 31 December 2024 and 31 December 2023 are summarised below:

(iii) Price risk

Listed Hydrogen Assets

Price risk is defined as the risk that the fair value of a financial instrument held by the Company or Group will fluctuate. Listed Hydrogen Assets are measured at fair value through profit or loss. As of 31 December 2024, the Company and Group held Listed Hydrogen Assets with an aggregate fair value of £nil (2023: £2,322,000). All other things being equal, the effect of a 10% increase or decrease in the value of the investments held at the year end would have been an increase or decrease of £nil in the Company and Group’s loss after taxation for the year ended 31 December 2024 and the Company and Group’s net assets at 31 December 2024 (2023: £232,200). At 31 December 2024, the sensitivity rate of 10% is regarded as reasonable due to the actual market price volatility experienced as a result of the economic impact on the Listed Hydrogen Assets.

Private Hydrogen Assets

The impact of market conditions on the Limited Partnership’s portfolio of Private Hydrogen Assets is reflected in the discount rate sensitivity analysis as outlined in the unobservable inputs table in note 4. The valuations may also be affected by the performance of the underlying investments in line with the valuation criteria in note 3. The Private Hydrogen Assets sensitivity analysis in note 4 recognises that the valuation methodologies employed involve different levels of subjectivity in their inputs primarily driven by changes in discount rate assumptions and weighting of the techniques employed.

Key variable inputs of Private Hydrogen Assets

The variable inputs applicable to each broad category of valuation basis will vary depending on the particular circumstances of each Private Hydrogen Asset valuation. An explanation of each of the key variable inputs is provided below and includes an indication of the range in value for each input, where relevant.

Selection of appropriate discount rates

The selection of an appropriate discount rate is assessed individually for each Private Hydrogen Asset. Publicly disclosed discount rates in the relevant sector and comparable asset classes, which may be procured from public sources or independent third-party expert advisers or for comparable market transactions of similar assets are used where available.

FUTURE FUEL. NOW 94

HydrogenOne Capital Growth plc Annual Report 2024

Selection of appropriate benchmarks

The selection of appropriate benchmarks is assessed individually for each Private Hydrogen Asset. The industry and geography of each Private Hydrogen Asset are key inputs to the benchmark selection, with either one or two key indices or benchmarks being used for comparison.

Selection of comparable companies

The selection of comparable companies is assessed individually for each Private Hydrogen Asset at the point of investment, and the relevance of the comparable companies is continually evaluated at each valuation point. The key criteria used in selecting appropriate comparable companies are the industry sector in which they operate and the geography of the Private Hydrogen Asset’s operations.

Application of valuation basis

Each Private Hydrogen Asset is assessed, and the valuation basis applied will vary depending on the circumstances of each Private Hydrogen Asset. DCF will be considered where appropriate forecasts are available. The valuation will also consider any recent transactions, where appropriate. For those Private Hydrogen Assets where a trading multiples approach can be taken, the methodology will factor in revenue, earnings or net assets as appropriate for the Private Hydrogen Asset.

Estimated sustainable earnings and cash flows

The selection of sustainable revenue or earnings and cash flows will depend on whether the Private Hydrogen Asset is sustainably profitable or not, and where it is not then sustainable revenues will be used in the valuation. The valuation approach will typically assess Private Hydrogen Assets based on the last twelve months of revenue or earnings, as they are the most recent available and therefore viewed as the most reliable. Where a Private Hydrogen Asset has reliably forecasted earnings previously or there is a change in circumstance at the business which will impact earnings going forward, then forward estimated revenue or earnings may be used instead.

Application of liquidity discount

A liquidity discount may be applied either through the calibration of a valuation against the most recent transaction, or by application of a specific discount.

Credit risk

The Company and Group are exposed to credit risk in respect of trade and other receivables and cash at bank. For risk management reporting purposes, the Company and Group considers and aggregates all elements of credit risk exposure (such as individual obligation default risk, country risk and sector risk).

31 December 2024 31 December 2023
£’000 £’000
Trade and other receivables 49 51
Cash and cash equivalents 2,833 4,626
Total 2,882 4,677

The cash and cash equivalents are held with Northern Trust Bank, EFG International Bank, Royal Bank of Scotland and through the Goldman Sachs- Liquid reserve fund. The Fitch Rating credit rating of Northern Trust Bank is AA (2023: AA), EFG International Bank is A (2023: A), Royal Bank of Scotland A+ (2023: A+) and the Goldman Sachs Liquid reserve fund is AAA (2023: AAA). At the year end there were no trade and receivables past due. The credit risk exposure is minimised by dealing with financial institutions with investment grade credit ratings.

Liquidity risks

Liquidity risk is the risk that the Company or Group may not be able to meet a demand for cash or fund an obligation when due. The Investment Adviser, AIFM and the Board continuously monitor forecast and actual cashflows from operating, financing and investing activities to consider payment of dividends, or further investing activities. Financial assets and liabilities by maturity at the year end are shown below:

Operational risk

Operational risk is the risk of direct or indirect loss arising from a wide variety of causes associated with the processes, technology and infrastructure supporting the activities relating to financial instruments, either internally or on the part of service providers, and from external factors other than credit, market and liquidity risks such as those arising from legal and regulatory requirements and generally accepted standards of investment management behaviour. Operational risk is managed so as to balance the limiting of financial losses and reputational damage with achieving the investment objective of generating returns to investors.# Notes to the parent and consolidated financial statements

The AIFM works with the Board to identify the risks facing the Company and the Limited Partnership. The key risks are documented and updated in the Risk Matrix by the AIFM. The primary responsibility for the development and implementation of controls over operational risk rests with the Board. This responsibility is supported by the development of overall standards for the management of operational risk, which encompasses the controls and processes at the service providers and the establishment of service levels with the service providers. The Directors’ assessment of the adequacy of the controls and processes in place at service providers with respect to operational risk is carried out through having discussions with and reviewing reports, including those on their internal controls, from the service providers.

Capital Management Policies and Procedures

The Company and Group’s capital management objectives are to ensure that the Company and Group will be able to continue as a going concern while maximising the return to equity shareholders. In accordance with the investment objective, the principal use of cash (including the proceeds of the IPO and placings) is investing in hydrogen focused assets, as well as expenses related to the share issue when they occur, ongoing operational expenses and payment of dividends and other distributions to shareholders in accordance with the Company’s dividend policy. The Company and Group considers their capital to comprise share capital, distributable reserves and retained earnings. The Company and Group are not subject to any externally imposed capital requirements. The Company and Group’s share capital, distributable reserves and retained earnings are shown in the Statement of Financial Position at a total £116,439,000 (2023: £132,670,000).
