ESS Tech (NYSE:GWH) announced its quarterly earnings results on Thursday. The company reported ($0.54) earnings per share (EPS) for the quarter, missing analysts’ consensus estimates of ($0.29) by ($0.25), FiscalAI reports.

ESS Tech had a negative net margin of 1,045.28% and a negative return on equity of 1,811.99%.

Here are the key takeaways from ESS Tech’s conference call:

• Project New Horizon announced with Salt River Project and Google for a 5 MW / 50 MWh pilot (manufacturing in 2026, targeted delivery December 2027) under a 10-year capacity agreement, providing a flagship commercial reference for ESS’s Energy Base.
• Independent, real-world validation was achieved—APPA’s 21-month DEED demonstration at Burbank Water & Power validated ESS’s non-flammable iron saltwater chemistry, and two systems were successfully commissioned at Turlock Irrigation District.
• ESS is expanding its addressable market via a letter of intent with Alsym Energy to jointly develop non-flammable sodium?ion short/medium-duration batteries and by acquiring VoltStorage IP and assets, strengthening its technology and IP base.
• Financials remain constrained—Q1 revenue was just $128k, net loss was $15.9M and adjusted EBITDA loss was $10.3M; liquidity totaled roughly $21.5M after a $15M registered direct offering, while net cash used in operations was $13.5M in the quarter.
• Management laid out a milestone-driven roadmap (200 kW Wilsonville commission in Q3 2026, first 800 kW client system H1 2027, then the 5 MW SRP delivery end of 2027) and says over 500 MW of scaled manufacturing capacity is in place to support commercialization.
