7:30 p.m. CEST - Adocia (Euronext Paris: FR0011184241 – ADOC, the “Company”), a clinical-stage biopharmaceutical Company focused on the research and development of innovative therapeutic solutions for the treatment of diabetes and obesity, today announced the establishment of a shareholder loan agreement with Vester Finance, repayable in new shares, with an option for the Company to repay in cash under certain conditions.

"We are delighted to complete this transaction proposed by Vester Finance as he is the largest shareholder after the Soula co-founders and has been involved in most of our financing transactions and fundraising campaigns over the past four years. In addition, Vester Finance has increased his equity position since the beginning of 2026, currently holding 4.2% of the share capital," says Olivier Soula, Chief Executive Officer of Adocia. "We are extending our cash runway with this guaranteed optional financing facility that will be used when required and on the initiative of the Company. This shareholder’s commitment and loyalty reflect its confidence in Adocia’s development and outlook.”

Use of Proceeds

As of March 31, 2026, the Company has a cash position of €12 million.

With a cash position reinforced by the €1.5 million received upon the signing of this transaction, and assuming that the full amount of this financing is utilized, the Company’s cash runway is extended to beginning Q2 2027, excluding revenue from future partnerships.

The funds raised through this financing will be used primarily for the development of BioChaperone® and AdoXLongTM platforms, and to help finance the Company's operating needs.

Main terms of the shareholder loan agreement

In accordance with the terms of the agreement signed on April 21, 2026, Vester Finance has agreed to provide the Company with shareholder loans up to a limit of €6.0 million over a period of 24 months, subject to certain customary contractual conditions, at an interest rate of 7.0% per annum payable in fine.

An initial advance of €1.5 million was paid immediately upon signing. The Company will be able to request further advances of up to €1.0 million each.

The shareholder loans may be repaid at any time, either in cash or by subscribing for newly issued shares of the Company, in accordance with the price and ceiling rules set by the 22nd resolution of the General Meeting of Shareholders of the Company of June 11, 2025 (the “General Meeting”) and in accordance with the applicable market rules. Interest would only apply in the event of repayment in cash.

New shares will be issued on the basis of the average market price preceding each issue¹, reduced by a maximum discount of 5%, subject to the pricing and ceiling rules set by the General Meeting², and up to a maximum of 1,500,000 newly issued shares of the Company, representing up to 7.6% of its share capital.

Beyond the amount of the initial advance, the Company will have the option to suspend or terminate this agreement at any time and at no cost.

This transaction was decided by the Chief Executive Officer acting pursuant to the sub-delegation of authority granted by the Company’s Board of Directors, itself acting pursuant to the delegation of authority granted to it by the 22nd resolution of the General Meeting³ to grant Vester Finance the right to subscribe for a maximum of 1,500,000 new shares under the terms set out in this press release.

This transaction is not subject to the preparation of a prospectus requiring an approval by the Autorité des Marchés Financiers (AMF), pursuant to Article 1 of Regulation (EU) 2017/1129 as amended (Prospectus Regulation), nor to the filing with the AMF of a document containing the information set out in Annex IX of the Prospectus Regulation.

The number of shares issued under this agreement and admitted to trading will be announced on the Company’s website.

Theoretical impact of the operation

Assuming that all of the 1,500,000 new shares are issued, the Company's share capital would amount to €2,110,780.60, divided into 21,107,806 ordinary shares with a par value of €0.10 each. A shareholder holding 1.00% of the Company's share capital before the operation would see his stake decrease to 0.929 % of the share capital on a non-diluted basis⁴, and 0.776% of the share capital on a diluted basis⁵.

Prior to the operation, the co-founders Soula held 5.4% of the Company's share capital and 9.2% of the voting rights, and Vester Finance 4.2% of the Company’s share capital and 3.9% of the voting rights.

After completion of this operation, the co-founders Soula will hold 5% of the Company’s share capital and 8.6% of the voting rights and Vester Finance 11% of the Company’s share capital and 10.3% of the voting rights.

This transaction will have no impact on the Company’s governance.

Vester Finance, acting here in its capacity as financier, may be required to sell all or part of the shares subscribed for in connection with this transaction within a shorter or longer timeframe. The sale of the shares on the market may have an impact on the volatility and liquidity of the security, as well as on the Company’s share price.
