After the Company's proposal was approved by the bondholders through a so-called written procedure and the Rights Issue was completed, the date for delivery of shares for the settlement was set for February 3, 2026. Midsummer has previously announced that the conversion under the bond, calculated as of December 31, 2025, would result in a total of SEK 79,164,446 under the bond loan being converted into 57,365,400 shares in Midsummer. In consideration of the fact that the write-down date for the bond has subsequently been set as January 27, 2026, accrued interest for the period from January 1, 2026, up to and including January 27, 2026, shall also be converted into shares. The final conversion amount is therefore SEK 79,636,764, which will be paid for a total of 57,707,800 shares in Midsummer. Each holder of one (1) bond on the record date of January 23, 2026, will receive 288,539 shares in Midsummer. All conversions will be made at a subscription price of SEK 1.38 per share. The conversion of interest for the period January 1, 2026, to January 27, 2026, has today been approved by the board of directors of Midsummer with the support of the authorization from the extraordinary general meeting in December 2025.

For further information on the agreement with the bondholders, please refer to Midsummer's press release dated November 28, 2025, and the reasons stated for the deviation from shareholders' preferential rights in the notice to the extraordinary general meeting published on the same day.
