ESS Tech Raises $3.2M in Stock Offering, Repays Debt

  • ESS Tech closed a $3.2M registered direct offering of 6.4M shares at $0.50 per share on August 21, 2026.
  • Concurrent private placement issued warrants for up to 12.8M additional shares at $0.50 per share.
  • $1.5M of proceeds will repay a promissory note to YA II PN, Ltd.
  • Remaining funds will support general corporate purposes and working capital.

This capital raise comes as ESS Tech competes in an increasingly crowded non-lithium energy storage market. The debt repayment suggests immediate financial pressure, while the warrant structure indicates long-term investor engagement. The $3.2M deal size reflects both the company's funding needs and current market valuation challenges.
