Update on the Combination of HICL Infrastructure PLC and The Renewables Infrastructure Group Limited

The Boards of HICL Infrastructure PLC ("HICL") and The Renewables Infrastructure Group Limited ("TRIG") confirm that, following the announcement of the proposed combination of the two companies on 17 November 2025, the proposed combination will not proceed.

Both Boards remain convinced of the strategic rationale for the combination. However, following broad engagement with shareholders, the HICL Board determined that it cannot progress the transaction without a substantial majority of support from its own investors.

Each company remains well positioned as an independent business, with high-quality portfolios, strong management teams, and clear strategies for delivering long-term value to investors.
