The Renewables Infrastructure Group Limited "TRIG" or "the Company", a London-listed renewables investment company advised by InfraRed Capital Partners ("InfraRed") as Investment Manager and Renewable Energy Systems ("RES") as Operations Manager.

Today, the joint announcement with the Board of HICL Infrastructure PLC ("HICL") sets out that HICL is withdrawing from the proposed combination with TRIG (the "Combination") announced on 17 November 2025. The Board of the Company regrets that investors will not have the opportunity to vote on the creation of the largest listed UK infrastructure investment company and the other benefits that the Board believes the Combination could have brought.

Richard Morse, Chair of TRIG, commented:

"Our focus now returns to delivering TRIG's attractive standalone strategy. TRIG is a well-established platform with high quality assets, a competitive pipeline of opportunities, and deep renewables and energy storage expertise. We are uniquely placed to capitalise on the demand growth for low carbon, reliable power and to capture the commercial opportunities as economies across the UK and Europe electrify and decarbonise. Doing so will allow us to deliver sustainable value and growth for our shareholders, with whom we will continue to engage on the path ahead."

At our Capital Markets Seminar on 29 May 2025, we set out our standalone strategy to deliver growth and value to our investors, supported by our managers, InfraRed and RES. The Board of TRIG remain confident in this strategy which positions TRIG well to continue delivering resilient income and growth through development, diversification and operational enhancement. For the avoidance of doubt, not progressing with the Combination in no way diminishes TRIG's standalone strategy.

The Board is grateful for shareholders' engagement at TRIG's Capital Markets Seminar and more recently in relation to the proposed Combination. We look forward to continuing our constructive dialogue with shareholders ahead of the 2026 Annual General Meeting and as we oversee the future strategy and capital allocation policy of the Company.
