Following the announcement of the final outcome of Diamyd Medical AB's (publ) ("Diamyd Medical" or the "Company") rights issue carried out in April 2025, it has come to the Company's attention that, due to administrative reasons, one subscription application was not included in the final outcome. As a result, an adjustment has been necessary. After this adjustment, the number of subscribed A-units in the rights issue amounts to 514,624 and the number of subscribed B-units amounts to 27,686,603. Consequently, this means that the number of B-units issued within the framework of the additional unit issue included in the rights issue amounts to 2,409,103. Through the rights issue, the additional unit issue, and the directed issue carried out on May 5, 2025, the Company will thus receive approximately SEK 267 million before issue costs, adjusted from the previously communicated amount of approximately SEK 266 million.
