(the Company or OSB Group )

Share repurchase programme

OSB Group announces that, as outlined in the announcement of its 2022 Full Year Results on 16 March 2023, it intends to commence, on 17 March 2023, a share repurchase programme to return up to £150 million to shareholders (the Share RepurchaseProgramme). The Share Repurchase Programme will help to deliver on OSB Group’s stated intention to deliver attractive and sustainable returns to shareholders across the cycle.

OSB Group has entered into a non-discretionary agreement (the Agreement) with Citigroup Global Markets Ltd (Citi) to undertake the Share Repurchase Programme on its behalf by making market purchases, as riskless principal, of OSB Group’s ordinary shares of one pence each (the Ordinary Shares) on the London Stock Exchange or another recognised investment exchange¹. Citi shall make trading decisions under the Share Repurchase Programme independently of OSB Group, subject to certain parameters agreed between Citi and the Company prior to the commencement of the Share Repurchase Programme and to the Company’s right to terminate the Agreement in certain limited circumstances.

Ordinary Shares acquired by Citi under the Agreement will be sold on to OSB Group. It is the Company’s present intention for such repurchased Ordinary Shares to be cancelled. The purpose of the Share Repurchase Programme is therefore to reduce OSB Group's share capital.  The maximum number of Ordinary Shares to be acquired under the Share Repurchase Programme is 44,972,602 as authorised by shareholders at the Company’s 2022 Annual General Meeting on 12 May 2022. The Share Repurchase Programme is expected to complete no later than 15 March 2024.

Any purchase of OSB Group Ordinary Shares contemplated by this announcement will be executed in accordance with OSB Group's general authority to repurchase Ordinary Shares granted by its shareholders at the 2022 Annual General Meeting on 12 May 2022, the Market Abuse Regulation 596/2014 and the Commission Delegated Regulation (EU) 2016/1052 (both as incorporated into UK domestic law by the European Union (Withdrawal) Act 2018), and Chapter 12 of the Financial Conduct Authority's Listing Rules.

Any repurchase of Ordinary Shares will be announced no later than 7.30 a.m. on the business day following the calendar day on which the repurchase occurred.
