PrimeStone Capital Pushes for Sale of Gresham House Energy Storage Fund
A 26% discount between share price and net asset value has triggered a fresh call for a formal sale process at Gresham House Energy Storage Fund. PrimeStone Capital, holding a 7% stake, argues that despite the board's strategic progress, the public market continues to undervalue the company’s core assets.

PrimeStone Capital claims the current share price of 96.8p fails to reflect the intrinsic value of the fund's portfolio. While acknowledging recent constructive dialogues with the board regarding alternative revenue streams and the potential of grid connections for data centers, the investor maintains that the listed structure creates an persistent, widening valuation gap. The firm’s analysis suggests that the fund's true worth sits closer to the 131.3p net asset value, a figure currently obscured by market pricing.
PrimeStone reports broad consensus among fellow shareholders that a formal sale process represents the most reliable mechanism to unlock this trapped value. The firm intends to press the board to prioritize this path, arguing that existing strategies, while positive, are insufficient to bridge the divide between asset performance and investor returns in the near term.
