PrimeStone Capital Responds to Gresham House Energy Storage Fund Plc Announcement

LONDON, Sept. 15, 2026 /CourierPR/ -- PrimeStone Capital, a shareholder with a 7% stake in Gresham House Energy Storage Fund plc (GRID), has issued a statement in response to the company’s recent announcement. The statement highlights the ongoing dialogue between PrimeStone and GRID’s board, management, and other shareholders, emphasizing a shared commitment to maximizing shareholder value.

According to PrimeStone, the company has found strong alignment with the GRID board regarding the potential for additional value in the company’s assets. Specifically, PrimeStone and the board agree that the company’s Alternative Revenues and the validation of grid connections for data centers hold significant promise. These assets are not currently reflected in the Net Asset Value (NAV) of GRID.

PrimeStone’s core belief remains unchanged: the listed structure of GRID is creating a widening gap between the intrinsic value being generated and the current share price. As of 10:00 on the day of the announcement, the share price stood at 96.8p, which equates to a 26% discount to the 131.3p NAV.

The press release also notes that while PrimeStone and the board share a common vision, there is significant support among other shareholders for a formal sale process as the most effective way to crystallize the value. PrimeStone is committed to continuing constructive dialogue with the board and other shareholders to ensure that maximum value is achieved for shareholders in a timely manner.

The company’s statement concludes by reiterating its dedication to working with GRID to achieve the best possible outcome for all shareholders.
