Zealand Pharma - Execution framework for share buy-back program

Copenhagen, Denmark, May 7, 2026 – Zealand Pharma A/S ("the Company" or “Zealand Pharma”) (Nasdaq: ZEAL) (CVR-no. 20045078), a biotechnology company transforming the future of metabolic health, today announced that it has decided to initiate a share buy-back program (the “Program”) in accordance with company announcement no. 13 / 2026. This regulatory update summarizes the execution framework of the Program, to which the following terms apply:

The Program will be implemented in accordance with Regulation (EU) No 596/2014 (the Market Abuse Regulation, “MAR”) and Commission Delegated Regulation (EU) 2016/1052 (the “Safe Harbour Regulation”).

The Company has appointed Danske Bank as lead manager for the Program. Danske Bank will make its own trading decisions independently of, and without influence from, the Company, within the terms of the Program as announced below and in accordance with applicable regulation.

The Program commences on May 7, 2026 and will be completed no later than October 31, 2026 unless it is terminated or suspended earlier by the Company. Further, Danske Bank may, at its discretion, complete the Program prior to the end of the stated period.

The purpose of the Program is to (i) meet obligations arising from the Company’s share-based incentive programs and (ii) reduce the share capital (potentially through subsequent cancellation of shares repurchased, subject to any necessary additional corporate resolutions), as applicable.

The Program is implemented under the following framework:

• The maximum total consideration for shares bought back under the Program is DKK 1.3 billion.
• The maximum number of shares that may be acquired under the Program is 7,152,557.
• Purchases will be carried out on Nasdaq Copenhagen.
• Shares may not be purchased at a price exceeding the higher of: (i) the price of the last independent transaction on the trading venue where the purchase is carried out and (ii) the highest current independent bid on that trading venue at the time of purchase. The shares may not be acquired at a price deviating more than 10% from the price quoted on Nasdaq Copenhagen A/S at the time of acquisition.
• The maximum number of shares that may be bought on any single trading day will not exceed 25% of the average daily trading volume of the Company’s shares on the relevant trading venue, based on the average daily volume during the preceding 20 trading days.
• The Company may suspend or terminate the Program at any time. Any such decision will be disclosed in a company announcement.
• On a weekly basis, the Company will issue a company announcement in respect of transactions made under the Program (in accordance with applicable requirements)

The Program is based on the prevailing authorization granted to the Board of Directors by the Annual General Meeting in March 2026 to acquire treasury shares.  Under this authorization, the Company may repurchase shares in the market, provided that the Company’s aggregate holdings of treasury shares do not at any time exceed a total nominal value of 10% of the Company’s share capital. Furthermore, pursuant to the authorization, the acquisition price for such treasury shares may not deviate by more than 10% from the quoted price of the Company’s shares on Nasdaq Copenhagen at the time of acquisition
