Grenoble, 9 October 2026, 7:00 p.m. - HRS , a French designer and manufacturer of hydrogen infrastructure and the European leader in hydrogen refueling stations (the “Company” or “HRS”), today announces that it has extended the subscription period for the capital increase announced on 29 September 2026 through 23 October 2026 at the latest, (the “Capital Increase”). The extension was granted to allow Arago Technologies, the parent company of Azur DataCenter, to complete the administrative formalities required prior to its subscription.

The Company has also been informed that one investor has withdrawn. As a result, the Capital Increase is expected to generate gross proceeds of €3.13 million, representing 82% of the €3.81 million initially targeted. It would comprise €1.65 million in cash and €1.48 million through the set-off of certain, liquid and due receivables from the Company. In parallel, the second €0.50 million tranche of ordinary bonds has already been fully subscribed.

Strengthening the cash position and extending the Company's cash runway

The Capital Increase and the second ordinary bond tranche would strengthen HRS's cash position by a total of €2.15 million in new liquidity. These transactions are expected to extend the Company's cash runway through February 2027. This runway does not include either cash inflows from potential new orders for which HRS is currently bidding or the resources that could be generated by the leaseback transaction.

HRS is also pursuing discussions with its longstanding banking partners to obtain bank financing, the terms of which will be adjusted to reflect the financing transactions described above, and which could be finalized in October 2026.

Completion and settlement of the headquarters sale-and-leaseback transaction, subject solely to the satisfaction of administrative conditions precedent, are expected by the end of 2026.

If all of these financing sources are secured, HRS estimates that it would have sufficient resources to fund its operations beyond 12 months.

Terms of the Capital Increase

The Capital Increase was approved by the Board of Directors on 28 September 2026 pursuant to the delegation of authority granted by the General Meeting of Shareholders held on 27 November 2025 under its 9^th resolution (capital increase by way of an offering referred to in Article L. 411-2, 1° of the French Monetary and Financial Code).

The subscription period was initially scheduled to run from 29 September through 7 October 2026.

However, due to the administrative formalities required for Arago Technologies' subscription, the Board of Directors resolved on 7 October 2026 to extend the subscription period through 23 October 2026 at the latest.
