Project to Transfer Lhyfe Shares to Euronext Growth

Nantes (France) – 1 April 2026 – 8:00 – At its meeting held on 30 March 2026, the Board of Directors of Lhyfe (Euronext Paris - FR0014009YQ1 - LHYFE), independent green hydrogen producer for the decarbonisation of industry and mobility, decided to initiate a project to transfer the listing of the Company's shares from the regulated market of Euronext Paris to Euronext Growth Paris, a market dedicated to growth companies.

Rationale for the transfer

This project, which will be submitted for approval at the next Annual General Meeting scheduled for 22 May 2026, is part of a coherent approach to adapt Lhyfe's market framework to its size and development profile.

Subject to shareholder approval and the agreement of Euronext Paris, the listing would be carried out through an accelerated procedure involving only existing shares, with no issuance of new securities.

This transfer would allow Lhyfe to evolve in a market environment better suited to its stage of maturity, while strengthening its visibility among investors specialised in supporting innovative, fast?growing companies. Euronext Growth Paris currently brings together more than 500 listed companies, including industrial, technological and energy transition players, offering a more flexible, less costly and more agile framework.

Key implications of the project of transfer (non-exhaustive list)

In accordance with applicable regulations, Lhyfe informs its shareholders about the main potential consequences of such a transfer, as from its effective date.

Although no longer required to do so, Lhyfe intends to retain, as best practices, certain governance and financial reporting rules applicable on the regulated Euronext Paris market, including the maintenance of the IFRS accounting framework and the audit committee.

Protection of minority shareholders

The protection of minority shareholders, in the event of a change of control, will be ensured on Euronext Growth Paris by the mandatory public offer mechanism if the threshold of 50% of the capital or voting rights is crossed, directly or indirectly, alone or in concert.

Furthermore, only the crossings of the 50% and 90% thresholds of the capital or voting rights, upwards or downwards, will have to be declared to the French Financial Markets Authority (AMF) and to the Company.

However, pursuant to current regulations, the Company will remain subject, for a period of 3 years from its delisting from Euronext Paris, to the mandatory public offer regime and to the information requirements regarding threshold crossings and declarations of intent applicable to companies listed on Euronext Paris.

To maintain good visibility of its shareholding structure, the Company indicates that it will keep in its by?laws the obligation to declare to it any crossing of the 2% threshold of the capital or voting rights and each multiple thereof.

Periodic reporting

The publication deadline for the half?year financial report (including the half?year financial statements and the related activity report) will be extended from 3 to 4 months after the end of the half?year. A limited review by the statutory auditors of these half?year financial statements will no longer be mandatory.

The content of the management report, including the corporate governance report, will be simplified, with certain disclosures no longer required (say?on?pay, items likely to have an impact in the event of a public offer).

The Company may choose between French GAAP and IFRS for the preparation of its consolidated financial statements. The Company indicates that it will continue to prepare its consolidated accounts in accordance with IFRS.

Ongoing disclosures

The obligation to communicate regulated information (including inside information) fully and effectively will remain unchanged.

Lhyfe will continue to provide accurate, precise and truthful information, by disclosing to the public any information likely to have a significant effect on the share price and any information regarding transactions by its managers, in accordance with Regulation (EU) No. 596/2014 of 16 April 2014 on market abuse.

Furthermore, persons discharging managerial responsibilities will remain subject to the obligation to disclose transactions carried out on the Company's securities.

Lhyfe will continue to use a professional information provider.

Governance

The General Meeting will no longer be consulted on the remuneration of corporate officers (say?on?pay) pursuant to Articles L. 22?10?8 et seq. of the French Commercial Code. The mandatory gender?balance rules within the Board of Directors set out in Articles L. 225?18?1 and L. 22?10?3 of the French Commercial Code will no longer apply, except in the event certain thresholds are exceeded.

Lhyfe will no longer be subject to Articles L. 821?67 et seq. of the French Commercial Code regarding the audit committee. However, Lhyfe intends to maintain this committee to preserve best governance practices.

General Meetings

The Company will no longer be required to publish a press release specifying how the documents submitted to the General Meeting are made available, nor to post the voting results on its website. Furthermore, the preparatory documents for the General Meeting (lightened content) will no longer have to be posted online 21 days before the meeting, but only on the date of the convening notice (at the latest 15 days before the meeting). Lhyfe will also no longer be required to broadcast its General Meetings live or to make a recording available on its website.

The rules for convening and admission to General Meetings will remain unchanged.

Share liquidity

As Euronext Growth is a multilateral trading facility (MTF) operated by Euronext and not a regulated market, transferring to this market could result in a change in the liquidity of the Company's shares compared with liquidity on the regulated Euronext Paris market. It is specified that the liquidity contract entered into by Lhyfe will be maintained after the transfer.

Indicative transfer timetable (subject to Euronext approval)

The detailed timetable — including the date of submission of the application to Euronext, the date of publication of the information document, and the delisting/admission date — will be communicated at a later stage. For guidance, recent comparable transfers suggest a delay of 2 to 3 months between shareholder approval and effective admission to Euronext Growth.
