Today, October 16, 2025, the subscription period begins in Lumito AB’s (publ) ("Lumito" or the "Company") rights issue of units consisting of shares and warrants with preferential rights for the Company's existing shareholders (the "Right Issue"), which the board of directors resolved on September 9, 2025, and was approved by the extra general meeting October 10, 2025. The subscription period in the Rights Issue runs from and including October 16, 2025, up to and including October 30, 2025. However, note that some banks and nominees may have an earlier deadline for subscription in the Rights Issue. Shareholders should therefore check with their bank or nominee if they have an earlier deadline for subscription.

Timetable for the Rights Issue

Subscription with preferential rights
The shareholders who, on the record date of October 14, 2025, were registered in the share register maintained by Euroclear and on behalf of the Company, directly registered shareholders, receive a pre-printed issue report with attached payment advice from Euroclear. In the event that a different number of subscription rights than those stated in the preprinted issue report are used for subscription the special application form, which is available on the Company's website www.lumito.se, shall be used as a basis for subscription through cash payment.

Shareholders whose holdings of shares in the Company were nominee-registered with a bank or other nominee on the record date do not receive an issue report or a special application form from Euroclear. Subscription and payment must then instead take place in accordance with instructions from the respective trustee.

Subscription without preferential rights
Notification of subscription without preferential rights by a nominee is made in accordance with instructions from the respective nominee. For subscription through an endowment insurance or an investment savings account, please contact your nominee. Application for subscription without preferential rights in other respects is done by electronic subscription with Bank ID on Mangold's website emission.mangold.se.
