ESS Tech Revenue Jumps in Fiscal Q2
ESS Tech (NYSE:GWH), a company known for its iron flow long-duration energy storage batteries, released earnings for the second quarter of fiscal 2025 on August 14, 2025. The headline from the release was a significant increase in GAAP revenue, reaching $2.4 million and met analyst consensus. Although the company’s GAAP net loss narrowed sharply year over year, liquidity remains a top concern, with a period-end cash balance of just $0.8 million despite recent capital-raising moves. The quarter showed real operational progress and commercial traction.
