Item 3. Source and Amount of Funds or Other Consideration.

On October 8, 2021 (the “Closing Date”), the Issuer, f/k/a ACON S2 Acquisition Corp. (“STWO”) consummated a merger pursuant to the Agreement and Plan of Merger, dated as of May 6, 2021 (the “Merger Agreement”), by and among STWO, SCharge Merger Sub, Inc., a wholly-owned direct subsidiary of STWO (“Merger Sub”), and ESS Tech Subsidiary, Inc., f/k/a ESS Tech, Inc. (“Legacy ESS”), pursuant to which Merger Sub merged with and into Legacy ESS, with Legacy ESS surviving as a wholly owned subsidiary of STWO (the “Merger,” and together with the other transactions contemplated under the Merger Agreement, the “Business Combination”). Subsequently, the Issuer changed its name from “ACON S2 Acquisition Corp.” to “ESS Tech, Inc.” The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by the full text of the Merger Agreement, a copy of which is attached hereto as Exhibit 1 and incorporated herein by reference.

On the Closing Date, each outstanding share of common stock of Legacy ESS was converted and exchanged for 1.47110014425 shares of Common Stock, pursuant to which (i) Craig Evans was issued 4,602,453 shares of Common Stock in merger consideration and (ii) Dr. Julia Song was issued 1,917,211 shares of Common Stock in merger consideration.

On November 9, 2021, the Issuer achieved the earnout milestone events for an aggregate of 15,675,002 shares of Common Stock (the “Earnout Stock”) issuable to the former stockholders of Legacy ESS pursuant to the Merger Agreement. As a result, and for no additional consideration, (1) Craig Evans received 724,426 shares of Earnout Stock and (2) Dr. Julia Song received 301,769 shares of Earnout Stock.

Also on November 9, 2021, upon final calculation of the expenses related to the Merger, the Issuer determined that the aggregate Transaction Expenses (as defined in the Merger Agreement) were lower than had been estimated


CUSIP No. 26916J106						Page 5 of 7 Pages

as of the Closing Date. Pursuant to the Merger Agreement, this lower amount of Transaction Expenses resulted in an Expense Shortfall (as defined therein), which increased the Adjusted Equity Value (as defined therein) of Legacy ESS. As a result, the Issuer issued an additional 125,958 shares of Common Stock as merger consideration, pro rata and for no additional consideration, to the former stockholders of Legacy ESS (the “Transaction Expense Adjustment Shares”), pursuant to which (1) Craig Evans received 5,821 shares of Common Stock and (2) Dr. Julia Song received 2,425 shares of Common Stock.

The information set forth in or incorporated by reference into Items 4, 5 and 6 of this Schedule 13D is hereby incorporated by reference in its entirety into this Item 3.
