COMPANY WEBINAR

Baillie Gifford US Growth Trust plc (the "Company") will host a live webinar regarding the Company's forthcoming Annual General Meeting and the resolutions requisitioned by the activist Saba Capital ("Saba") on Monday, 28 September 2026, at 2pm.

The webinar will include a discussion with the Company's Chair, Tom Burnet and Senior Independent Director, Sue Inglis, who will explain why they believe the resolutions proposed by Saba would severely compromise the independence of the Board and could also, in effect, herald the end of the Company's existing highly differentiated and successful US growth strategy as shareholders know it.

Registration to attend the webinar is available at: www.bgusgrowthtrust.com

Questions may be submitted during the live presentation.

Shareholder participation is crucial: every vote matters and every vote not cast lowers the effective hurdle for Saba's nominees to secure Board seats, which will compromise the independence of the Board and is expected to signal the end of the Company's current strategy, heralding its transition into a vehicle for Saba's own benefit. Shareholders are strongly encouraged to VOTE AGAINST the SABA resolutions (1-3) and VOTE FOR the COMPANY resolutions (4-14) to preserve the independence of the Board and the current strategy for the Company.
