Novonesis (Novozymes A/S)

Initiation of Novonesis’ share buyback program

Today, Novonesis will initiate the first tranche (the “First Tranche”) of the EUR 1 billion multi-year share buyback program announced in Company Announcement No. 14, on August 19, 2026. Under the First Tranche, Novonesis will acquire B shares for an aggregate amount of up to EUR 75 million, with the First Tranche expected to end no later than December 17, 2026. Based on the closing share price on September 11, 2026, the First Tranche corresponds to around 1.3 million B shares. The shares acquired under the First Tranche will be used to meet obligations arising from employee share-based incentive programs.

The maximum number of shares acquired by the company per daily market session will be equivalent to no more than 25% of the average volume of shares in the company traded on NASDAQ OMX Copenhagen during the preceding 20 business days. The share buyback program will be conducted in accordance with Article 5 of Regulation (EU) No. 596/2014 (Market Abuse Regulation) and Commission Delegated Regulation (EU) 2016/1052 (the Safe Harbour Rules).
