FOR IMMEDIATE RELEASE

Galliford Try Holdings plc

LAUNCH OF SHARE BUYBACK PROGRAMME

Galliford Try Holdings plc (the "Company") today announces that it intends to commence a share buyback programme, subject to market conditions, to purchase ordinary shares of 50 pence each in the Company ("Ordinary Shares") for up to a maximum consideration of £10 million from the date of this announcement (the "Buyback").

As highlighted in its results for the year ended 30 June 2025, published separately this morning (which disclosed the Buyback), the Galliford Try group (the "Group") delivered another year of profitable growth, resulting in profit before tax improving by 28%. The strong visibility of future work streams and revenue, an order book of £4.1bn (2024: £3.8bn) and a well-capitalised debt-free balance sheet provides the Company's directors (the "Board") with confidence in the Group's future performance.

The Group's capital allocation priorities remain unchanged.  A strong balance sheet is a fundamental element in delivering the Group's Sustainable Growth Strategy, as it provides a competitive advantage in the market, supports the Group's disciplined approach, and provides confidence to the Group's clients and supply chain.  The Group's capital allocation priorities continue to be, in order of priority, investing in the business organically and inorganically, paying sustainable dividends to its shareholders, and returning excess cash to its shareholders.

The Group continues to actively evaluate its cash requirements to ensure it remains well positioned to deliver its Strategy to 2030, while maintaining adequate resources to support ongoing investment in the business. In line with this approach, the Company intends to commence a further modest share buyback. The quantum of the Buyback reflects a disciplined capital return strategy, preserving financial flexibility to pursue other strategic investment opportunities as they arise.  It is the Board's intention that the Buyback will be completed within the current financial year, ending 30 June 2026.

The Buyback represents the third share buyback programme that Galliford Try has undertaken in recent years, having returned £25m across two previous programmes, the most recent of which completed in May 2025.

The Company has entered into an agreement with Peel Hunt LLP ("Peel Hunt") and Panmure Liberum Limited ("Panmure Liberum") to conduct the Buyback, each acting as "riskless" or "matched" principal in accordance with certain contractually agreed parameters. The agreement provides Peel Hunt and Panmure Liberum with the authority to carry out market purchases under the Buyback independently of the Company within the agreed parameters. Peel Hunt will conduct the first tranche of the Buyback, which will be for circa £5.0 million. The second tranche of the buyback will be conducted by Panmure Liberum, the company's Joint Broker. The Company will release a further announcement in due course confirming arrangements for the remainder of the programme.

The purpose of the Buyback is to reduce the share capital of the Company and return funds to shareholders who wish to sell their Ordinary Shares. The Ordinary Shares purchased under the Buyback will be cancelled.

The directors of the Company consider the Buyback to be in the best interests of the Company and of its shareholders generally, with the implementation of the Buyback expected to enhance earnings per share.

Any purchase of Ordinary Shares under the Buyback will be carried out on the London Stock Exchange and/or other trading venues. The Buyback will be conducted in accordance with the general authority to repurchase Ordinary Shares granted by the Company's shareholders at the 2024 annual general meeting and to be sought at the 2025 annual general meeting, as well as UKLR 9.6 of the Financial Conduct Authority's UK Listing Rules. All Ordinary Shares purchased under the Buyback will be purchased within the parameters as to price and volume as specified in the relevant shareholder authorities.

Due to the limited liquidity in the Ordinary Shares, a buy-back of ordinary shares on any trading day may represent a significant proportion of the daily trading volume in the Ordinary Shares and may exceed the 25% of the average daily trading volume specified in the provisions of the UK Market Abuse Regulation dealing with buyback programmes and accordingly the Company may not benefit from the exemption contained in Article 5(1) of that regulation.

The Company will make further regulatory announcements to shareholders in respect of purchases of Ordinary Shares under the Buyback no later than 7:30 am on the business day following the calendar day on which the purchase occurred.

The person responsible for making this announcement on behalf of the Company is Kevin Corbett, General Counsel & Company Secretary.
