Commencement of 2026 Share Buyback Programme

International Workplace Group plc ("IWG" or the "Company") confirms that following the last acquisition of shares on 29 December 2025, the $130m share buyback programme for 2025 has now been completed in accordance with its terms at a weighted-average price of 201p.

IWG today announces the launch of a new share buyback programme for 2026, commencing on 2 January 2026, for an initial tranche of up to $50m and expects to announce further tranches during 2026 in a similar manner to how the buyback was conducted during 2025. The next update will be provided at the full-year results on 3 March 2026.

The Company has entered into an arrangement with Jefferies International Limited ("Jefferies") to conduct the 2026 share buyback programme. The programme allows Jefferies to purchase (a) prior to the expiration of the Company's current buyback authority granted by shareholder resolution dated 20 May 2025, 104,868,089 ordinary shares in the Company ("Shares") and, taking into account purchases by the Company since that date, the maximum number of Shares which the Company may purchase pursuant to that authority is 72,104,930); and (b) following such expiration, the aggregate number of Shares authorised to be purchased by the Company under any subsequent buyback authority granted during the arrangement.

The Shares will be purchased in open market transactions and may be executed from time to time depending on market conditions, share price, trading volume and other factors. The programme will run from 2 January 2026 until no later than 31 December 2026 and purchases may continue during any closed period to which the Company is subject during the above‐mentioned period. These share purchases will be made by Jefferies acting as riskless principal.

Any share purchases effected pursuant to the arrangement will be subject to the terms of the arrangement with Jefferies and in any case will be effected in a manner consistent with the general authority vested in the Company to repurchase shares, the Market Abuse Regulation 596/2014, the Commission Delegated Regulation (EU) 2016/1052 (both as incorporated into UK domestic law) and the UK Listing Rules. The aggregate purchase price under this arrangement will not exceed US$50,000,000.

All Shares purchased through this arrangement will be cancelled. The sole purpose of these share purchases is to reduce the Company's share capital.
