Suominen Corporation’s stock exchange release on June 5, 2026, at 12:00 p.m. (EEST)

NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, DIRECTLY OR INDIRECTLY, IN OR INTO, OR TO ANY PERSON LOCATED OR RESIDENT IN, THE UNITED STATES, AUSTRALIA, CANADA, HONG KONG, NEW ZEALAND, JAPAN, SINGAPORE, SOUTH AFRICA OR ANY OTHER JURISDICTION IN WHICH THE RELEASE, PUBLICATION OR DISTRIBUTION WOULD BE UNLAWFUL.

Suominen Corporation (“Suominen” or the “Company”) disclosed on 18 May 2026 that it is planning a share issue based on the pre-emptive right of the shareholders to raise gross proceeds of up to approximately EUR 28 million (the “Offering”). The Board of Directors of Suominen has proposed that the extraordinary general meeting (“EGM”) to be held on 8 June 2026 resolve to authorise the Board of Directors of the Company to decide on a rights issue.

Suominen had previously disclosed on 18 May 2026 that the Company’s main shareholders, Ahlstrom Capital B.V., separately, and Etola Group Oy and Oy Etra Invest Ab, acting jointly, together representing a total of 49.02 per cent of the Company’s shares, have undertaken to subscribe for their pro rata share of new shares issued in the Offering (the “Subscription Undertakings”). In addition, Ahlstrom Capital B.V., separately, and Etola Group Oy and Oy Etra Invest Ab, acting jointly, have provided subscription guarantee commitments collectively covering the remainder of the Offering (the “Underwriting”). No compensation will be paid to the shareholders for providing their Subscription Undertakings or Underwriting.

The Subscription Undertakings and the Underwriting have been subject to, among other things, the Finnish Financial Supervisory Authority granting, pursuant to Chapter 11, Section 26 of the Finnish Securities Markets Act (746/2012, as amended), the parties that have given the respective commitments permanent exemptions from the obligation to launch a mandatory tender offer for the remaining securities entitling to the Company’s shares in the event that the holding of Ahlstrom Capital B.V., separately, and Etola Group Oy and Oy Etra Invest Ab, acting jointly, would consequently exceed 30 per cent of all votes carried by the Company’s shares as a result of the Offering.

Suominen has today been informed by Ahlstrom Capital B.V. and A. Ahlström Oy as well as Erkki Etola, Etola Group Oy and Oy Etra Invest Ab (the “Applicants”) that the Finnish Financial Supervisory Authority has today decided to grant the Applicants permanent exemptions from the obligation to launch a mandatory tender offer, even if the share of voting rights of Ahlstrom Capital B.V. and, indirectly, A. Ahlström Oy, or of Etola Group Oy and Oy Etra Invest Ab, acting jointly, or Erkki Etola indirectly alone, in the Company were to exceed the 30 per cent threshold for the obligation to launch a mandatory tender offer when the Subscription Undertakings and the Underwriting are exercised. The threshold could be exceeded upon Ahlstrom Capital B.V., separately, or in the case of Etola Group Oy and Oy Etra Invest Ab, acting jointly, subscribing for the Company’s shares in the Offering pursuant to the Subscription Undertakings and the Underwriting, depending on whether other shareholders or investors subscribe for all the remaining shares offered in the Offering.

The exemptions are conditional on that the Applicants or persons acting in concert with the Applicants do not acquire or subscribe for additional shares in the Company or otherwise increase their share of voting rights in the Company after the threshold for launching a mandatory tender offer has been exceeded. In addition, the Finnish Financial Supervisory Authority has stated in its decision that, unless the position of minority shareholders has been adequately safeguarded by other means, a precondition for granting an exemption from the obligation to launch a mandatory public takeover bid in such cases is that shareholders independent of the arrangement resolve on the arrangement at the general meeting of the target company.
