ESS Tech Cuts Costs, Secures Defense Contract Amid Revenue Decline

  • Q1 2026 revenue dropped 78% YoY to $128K due to fewer equipment deliveries.
  • Operating expenses fell 33% YoY to $6.7M, driven by reduced sales and marketing costs.
  • Secured a $9.9M contract with the U.S. Air Force Research Laboratory for a 27 MWh energy storage system.
  • Completed $15M registered direct offering at $1.75 per share, boosting liquidity to $21.5M.
  • Appointed Randy Selesky as Chief Commercial Officer to lead global commercial strategy.

ESS Tech is pivoting to execution and capital discipline amid a challenging commercialization phase. The company's focus on long-duration energy storage aligns with growing demand for resilient, domestically produced solutions, but its ability to scale operations and secure binding orders remains critical. The $9.9M defense contract and strategic partnerships signal potential upside, but revenue decline highlights the hurdles ahead.
