ESS Tech, Inc. (GWH) presents a deeply negative liquidation posture as of March 31, 2026. Total assets of $48.6 million face severe haircuts: unrestricted cash of $15.5 million recovers at par, short-term investments of $6.0 million recover near par, accounts receivable of $37K recovers near par, and prepaid/other current of $2.4 million recovers at minimal value. PP&E gross of $37.6 million less $21.3 million accumulated depreciation yields net book value of $16.3 million, which at a 50-60% liquidation haircut recovers perhaps $8-10 million. Inventory net of $123K (against $7.2 million in valuation reserves against $7.3 million gross) has minimal recovery. Intangibles of $2.6 million and ROU assets aggregate to roughly $6 million with zero to minimal recovery. Rough liquidation asset recovery: approximately $32-34 million. Against this, total liabilities of $39.1 million stand at face value. The finance lease liability alone totals $18.0 million ($9.0M current, $9.0M noncurrent) and represents the single largest liability component. Operating lease liabilities add $3.4 million. Deferred revenue (contract liabilities) of $5.6 million and a customer refund liability of $4.9 million are obligations that survive wind-down. Accrued and other current liabilities round out the stack. Net equity book value is $9.4 million, but under liquidation the recovery to equity is negative, consistent with MFFAIS CLV/LLV estimates of approximately negative $18 million. The company has explicitly disclosed substantial going concern doubt, with $21.5 million total liquid assets against $13.5 million quarterly operating cash burn. The Yorkville Promissory Note (up to $40 million, 8% OID, three amendments through February 2026) added $8.1 million in warrant-related APIC this quarter, indicating ongoing dilutive financing. The EXIM Credit Agreement ($22.7 million facility, undrawn) carries a restricted cash collateral requirement that partially constrains available liquidity. Revenue for Q1 2026 was $128K against cost of revenue of $7.2 million, yielding a gross loss of $7.0 million. Accumulated deficit stands at $861.7 million. The board has explicitly flagged potential liquidation, wind-down, or restructuring as outcomes if capital is not raised. Under the liquidation lens, equity recovery is definitively negative.
