ESS Cuts Losses, Eyes 2027 Project Deliveries Amid Leadership Overhaul
Event summary
- ESS reported a net loss of $63.4M for 2025, down from $86.2M in 2024, with revenue at $1.6M.
- Adjusted EBITDA improved 38% YoY to $(44.3)M, driven by a 33% reduction in operating expenses.
- Acquired VoltStorage GmbH’s IP and assets, appointing its former CCO as ESS’s Chief Commercial Officer.
- Secured a $9.9M contract for a U.S. military energy storage system and Google’s participation in Project New Horizon.
- Raised $40M from Yorkville Advisors and $15M in a registered direct offering post-year-end.
The big picture
ESS’s strategic pivot toward financial discipline and commercial expansion aligns with rising demand for resilient, long-duration energy storage solutions. The acquisition of VoltStorage and defense contracts signal a push into critical applications, but execution risks remain as the company scales manufacturing and delivery capabilities. The improved EBITDA and liquidity position provide a buffer, but the path to profitability hinges on converting its active pipeline into revenue.
