The Board of Directors of Vestas Wind Systems A/S has decided to initiate a new share buy-back programme of up to DKK 747m (approx. EUR 100m). The share buy-back programme is initiated pursuant to the authorisation granted to the Board of Directors by the Annual General Meeting in April 2026, which entitled Vestas to acquire treasury shares at a nominal value not exceeding 10 percent of the share capital at the time of the authorisation. The share buy-back programme will be executed in accordance with Regulation No. 596/2014 of the European Parliament and of the Council of 16 April 2014 on market abuse (MAR) and the Commission Delegated Regulation (EU) 2016/1052 of 8 March 2016 (the "Safe Harbour” Regulation). Purpose The purpose of the share buy-back programme is to adjust Vestas’ capital structure and meet obligations relating to the Group’s share-based incentive programmes. Time frame The share buy-back programme will run from 7 May 2026 and until no later than 11 August 2026. Terms Vestas has appointed Danske Bank as Lead Manager for the share buy-back programme. Danske Bank will make its own trading decisions independently of and without influence or involvement from Vestas. Under the share buy-back programme, Vestas may repurchase shares up to a maximum amount of DKK 747m, and no more than 7,500,000 shares, corresponding to 0.8 percent of the share capital of Vestas Wind Systems A/S. No shares may be bought back at a price exceeding the higher of i) the price of the last independent trade and ii) the highest current independent bid at the trading venue, on which the purchase is carried out, at the time of trading. The maximum number of shares that may be purchased on each trading day may not exceed 25 percent of the average daily trading volume of shares on the trading venue, on which the purchase is carried out, over the last 20 trading days prior to the date of purchase. Prior to the buyback Vestas holds 10,045,201 treasury shares, equal to 1.0 percent of the share capital. Vestas is entitled to suspend or stop the programme at any time subject to a disclosure of a company announcement. On a weekly basis, Vestas will issue an announcement in respect of transactions made under the programme.
