Offer to Warrant Holders – How to Exercise Your Warrants Series 2025/2026

The last day of trading in warrants series 2025/2026 is 22 April 2026. To prevent your warrants from expiring, you must subscribe for new shares by exercising your warrants no later than 24 April 2026.

Your warrants may be registered in one of two ways:

1. In a securities account at a bank or with another custodian (for example Avanza or Nordnet), in an investment savings account (ISK), or in an endowment insurance policy (KF). In this case, your warrants are nominee-registered.

2. In a CSD account (a CSD account begins with three zeros). In this case, your warrants are directly registered.

If Your Warrants Are Nominee-Registered

Subscription and payment for new shares, through the exercise of warrants, shall be made to the respective bank or other custodian where the warrants are registered. Subscription and payment shall be made in accordance with the instructions provided by each such bank or custodian. Banks/custodians usually send a digital notification to the account holder; otherwise, it is usually sufficient to log in to the securities account from the first day of the exercise period in order to receive instructions on how to exercise warrants to subscribe for new shares. Please contact your bank or custodian if you cannot find these instructions. Note that banks and other custodians may set different deadlines for subscription; it is therefore recommended to contact your bank/custodian early during the exercise period for information on subscription and payment. Subscribed and paid shares may be registered in your securities account as "interim shares" or "IA" until the registration of the new shares is completed at the Swedish Companies Registration Office (Bolagsverket), at which point interim shares will automatically be converted to shares in Modus Therapeutics.

If Your Warrants Are Directly Registered

Subscription for new shares, through the exercise of warrants, shall be made by submitting a fully completed subscription form to Bergs Securities. Payment shall be made in connection with the submission of the subscription form to Bergs Securities, in accordance with the payment instructions on the subscription form. The completed subscription form and payment must be received by Bergs Securities no later than 24 April 2026. Subscribed and paid shares will be registered in your CSD account as "interim shares" ("IA") until the registration of the new shares is completed at the Swedish Companies Registration Office (Bolagsverket), at which point interim shares will automatically be converted to shares in Modus Therapeutics.
