Publication of a Circular

The Directors of Baillie Gifford UK Growth Trust plc (the Company) are seeking shareholder authority for proposals to renew the Company's share buyback authority.

Accordingly, the Company has today published a circular (the Circular) setting out details of these proposals. The Circular also includes the notice of meeting to convene a general meeting (the General Meeting) at which the appropriate shareholder authority will be sought. The General Meeting will be held at 10 a.m. on 3 July 2025 at the offices of Baillie Gifford & Co at 3 St Helen's Place, London, EC3A 6AB.

The Board believes that the renewal of the buyback has the following benefits:

· to give confidence to the market that the Directors intend to pursue the stated policy of maintaining a single digit discount in normal market conditions;

· to provide additional liquidity in the Ordinary Shares;

· to reduce the volatility in the discount to NAV represented by the Ordinary Share price; and

· to generate a modest increase in value for existing Shareholders by buying back shares at a discount to the prevailing NAV.

Terms used and not defined in this announcement shall have the meanings given to them in the Circular.

A copy of the Circular will shortly be submitted to the National Storage Mechanism (NSM) and will be available for inspection at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism*

The Circular will also be available shortly on the Company's website, www.bgukgrowthtrust.com

*Neither the NSM website nor the Company's website nor the content of any website accessible from hyperlinks on those websites (or any other website) is (or is deemed to be) incorporated into, or forms (or is deemed to form) part of this announcement.
