ESS Tech, Inc. (NYSE: GWH) reported a small insider sale on February 20, 2026, when CFO Kate Eileen Suhadolnik disposed of 741 shares of common stock, according to a Form 4 filed with the Securities and Exchange Commission. The shares were sold at $1.54 apiece, producing gross proceeds of $1,141.
The filing states the disposition was undertaken to satisfy tax withholding obligations arising from the vesting of restricted stock units. After the sale, Suhadolnik directly holds 164,414 shares of ESS Tech common stock. A portion of those holdings remain in the form of restricted stock units, each representing a contingent entitlement to one share of the company's common stock.
Market data show the stock traded higher after the sale, reaching $1.66, though the shares are still lower by roughly 54% over the past 12 months. The transaction is modest in dollar terms but comes at a time when the company has disclosed several material financing and strategic moves.
InvestingPro data cited in company disclosures suggests ESS Tech is experiencing rapid cash consumption and carries a financial health assessment labeled as "WEAK." That data also notes a potential valuation disconnect, with fair value analysis indicating the stock may be undervalued at current levels. The company is scheduled to report quarterly results on March 2, three days after the reported insider sale.
In recent corporate activity, ESS Tech completed a registered direct offering that raised $15 million. The placement comprised 8,571,428 shares of common stock and pre-funded warrants, with a stated price of $1.75 per share. That per-share price was described as a premium relative to the closing price on January 28.
Strategically, ESS Tech has acquired the intellectual property and other assets of VoltStorage GmbH. The purchase includes patents, technical development work in iron-salt battery technology, and key personnel who worked on that technology. Company statements indicate the acquisition is intended to integrate complementary iron-based battery capabilities into ESS Tech’s energy storage portfolio.
ESS Tech also announced an executive hire, naming Randy Selesky as chief commercial officer. Selesky, noted as having more than 20 years of industry experience, will be responsible for the company’s global commercial strategy and business development efforts.
Taken together, the insider sale, financing activities, IP acquisition, and commercial hire mark a busy period for ESS Tech as it seeks to extend its market presence and technological capabilities while confronting cash flow and financial health concerns. Investors will have an opportunity to reassess company performance and outlook when management releases its earnings results on March 2.
