    Explanatory Note

        This Schedule 13D constitutes a late filing due to administrative error. This Schedule 13D reflects an aggregate 1,034,441 shares of Common Stock issued to Craig Evans and Dr. Yang (Julia) Song (the “Reporting Persons,” and each, a “Reporting Person”) as of November 9, 2021 (as previously disclosed in the Form 4 filed by the Reporting Persons with the SEC on November 12, 2021 and amended on November 17, 2021) causing the Reporting Persons to jointly hold over 5% of the Issuer’s outstanding shares of Common Stock, which consisted of: (i) 1,026,195 shares of Earnout Stock (as defined below) and (ii) 8,246 Transaction Expense Adjustment Shares (as defined below). As of the date of this Schedule 13D, the aggregate holdings of the Reporting Persons is 8,453,903 shares of Common Stock representing approximately 5.5% of the total outstanding shares of Common Stock.

    Item 1.    Security and Issuer.
     
    This Schedule 13D relates to the Common Stock of ESS Tech, Inc, a Delaware corporation (the “Issuer”). The address of the principal executive offices of the Issuer is 26440 SW Parkway Ave., Bldg. 83 Wilsonville, Oregon 97070.
     
    Item 2.    Identity and Background.

    (a)This Schedule 13D is being filed jointly by the Reporting Persons – Craig Evans, an individual, and Julia Song, an individual. Craig Evans and Julia Song are married to each other.
    (b)The Reporting Persons’ business address is 26440 SW Parkway Ave., Bldg. 83 Wilsonville, Oregon 97070.
    (c)The present principal occupation of Craig Evans is Co-Founder and Advisor to the Chief Executive Officer of the Issuer. The present principal occupation of Dr. Julia Song is Chief Technology Officer and Co-Founder of the Issuer.
    (d)Neither Reporting Person has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).
    (e)Neither Reporting Person has during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction, and as a result of such proceeding was or is subject to any judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.
    (f)United States of America.
     
    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.

    Item 4.    Purpose of Transaction.

In such capacities, the Reporting Persons may have or may have had influence over the corporate activities of the Issuer, including activities that may relate to the items described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

    Subject to the Issuer’s Insider Trading Policy, the Reporting Persons may from time to time buy or sell securities of the Issuer as appropriate for their personal circumstances, including “sell-to-cover” transactions to satisfy tax withholding obligations related to the vesting of RSUs. As such, the Reporting Persons have and will continue to engage in “sell-to-cover” transactions. The Reporting Persons may, from time to time, purchase additional securities of the Issuer either in the open market or in privately negotiated transactions, depending upon the Reporting Persons’ evaluation of the Issuer’s business, prospects and financial condition, the market for such securities, other opportunities available to the Reporting Persons, general economic conditions, stock market conditions and other factors. Depending upon the factors noted above, the Reporting Persons may also decide to hold or dispose of all or part of his investments in securities of the Issuer and/or enter into derivative transactions with institutional counterparties with respect to the Issuer’s securities. However, the Reporting Persons reserve the right to formulate in the future plans or proposals which may relate to or result in the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

    (c) Except as described in this Schedule 13D, the Reporting Persons have not effected any transactions in the Common Stock during the 60 days prior to November 9, 2021 or during the 60 days prior to the date hereof except that on May 20, 2023, the Reporting Persons sold 21,479 shares of Common Stock, representing 0.01% of the total outstanding shares of Common Stock, in “sell-to-cover” transactions to fund the Reporting Persons’ tax withholding obligations in connection with the vesting of RSUs, which were effected through an open market brokerage transaction.

    (d) To the knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any shares of Common Stock beneficially owned by the Reporting Persons.
    (e) Not applicable.
