Non-Discretionary Share Buyback Programme

SSE PLC

Non-Discretionary Share Buyback Programme

As previously announced on 26 August 2026, SSE plc (the “Company” or “SSE”) intends to repurchase ordinary shares up to a maximum pecuniary amount of £105,000,000 (the “Buyback”). The purpose of the Buyback is to reduce the share capital of the Company to honour SSE’s commitment to cap scrip dividend take-up at 25% in respect of the financial year ended 31 March 2026, in line with the Company’s dividend plan to 2029/30. 

The Company has provided irrevocable, non-discretionary instructions to UBS AG London Branch (“UBS”) in relation to the Buyback. The Buyback will commence on Monday, 12 October 2026 and end no later than 31 January 2027 (the “Programme”). UBS will act as principal for the simultaneous on-sale of such shares to the Company and will make its trading decisions independently of the Company.

The maximum number of ordinary shares to be acquired under the Programme will not exceed 4,246,975. The repurchased ordinary shares will be held in treasury pending their cancellation or re-issue in due course.

Any acquisitions under the Programme will be carried out within certain pre-set parameters, and in accordance with the Company's general authority to repurchase ordinary shares granted by shareholders at the Company’s Annual General Meeting on 16 July 2026 (being up to 121,219,176 ordinary shares), Chapter 9 of the Financial Conduct Authority’s UK Listing Rules, the Market Abuse Regulation (596/2014) as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018 and as amended (including by the Market Abuse (Amendment) (EU Exit) Regulations 2019) (“MAR”) and the Commission Delegated Regulation (EU) 2016/1052 of 8 March 2016 supplementing Regulation (EU) No 596/2014 of the European Parliament and of the Council with regard to regulatory technical standards for the conditions applicable to buy-back programmes and stabilisation measures as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018 and as amended (including by the Technical Standards (Market Abuse Regulation) (EU Exit) Instrument 2019).

The Company confirms that it currently has no unpublished inside information. The Company will make further regulatory announcements in respect of purchases of ordinary shares under the Programme by no later than the end of the 7th daily market session following the date of such purchase.
