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

On September 14, 2022 (the “Closing Date”), pursuant to a Business Combination Agreement, dated as of May 11, 2022 (the “Business Combination Agreement”), by and among the Issuer, Kensington Capital Merger Sub Corp., a Delaware corporation (“Merger Sub”), and Amprius Technologies Operating, Inc. (“Legacy Amprius”), a business combination between the Issuer and Legacy Amprius was effected through the merger of Merger Sub with and into Legacy Amprius, with Legacy Amprius surviving such merger as a wholly owned subsidiary of the Issuer (together with the other transactions contemplated by the Business Combination Agreement, the “Business Combination”).

In connection with the Business Combination, the Reporting Person acquired options to purchase an aggregate of 3,457,763 shares of Common Stock.

On March 19, 2024, the Reporting Person received a grant of 1,419,670 restricted stock units. As of the date of this Schedule 13D, 177,459 of such restricted stock units have vested.

On October 23, 2024, Amprius, Inc. (“Amprius Holdings”), which was the majority stockholder of the Issuer, voluntarily liquidated and dissolved. In connection with the liquidation and dissolution of Amprius Holdings, the Issuer assumed from Amprius Holdings the outstanding options to purchase shares of Amprius Holdings’ Class A common stock (the “Holdings Options” and, each such option, a “Holdings Option” and such assumption, the “Option Assumption”).

As a result of the Option Assumption, each Holdings Option became an option to purchase a number of shares of Common Stock (collectively, the “Assumed Options”), and the terms of the Holdings Options, including the number of shares of Common Stock underlying the Assumed Option and the exercise price, were adjusted in a manner that was designed to comply with the requirements of U.S. Internal Revenue Code treasury regulation relating to equity grant assumptions. In connection with the Option Assumption, the Reporting Person acquired options to purchase an aggregate of 4,774,633 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 connection with the Business Combination, the Reporting Person received options to purchase 3,457,762 shares of Common Stock with a weighted average exercise price of $1.72 per share in exchange for options to purchase 2,375,000 shares of Legacy Amprius common stock with a weighted average exercise price of $2.50 per share. Of such options, options to purchase 2,680,528 shares of Common Stock remain subject to certain ongoing vesting conditions as of the date of this Schedule 13D.

In connection with the Option Assumption, the Reporting Person received options to purchase 4,774,633 shares of Common Stock with a weighted average exercise price of $2.40 per share in exchange for options to purchase 6,877,722 shares of Holdco’s Class A common stock with a weighted average exercise price of $1.66 per share. All such options are fully vested as of the date of this Schedule 13D.

The Reporting Person serves as Chief Executive Officer of the Issuer and as a member of the Issuer’s board of directors and, in such capacities, may have influence over the corporate activities of the Issuer, including activities which may relate to items described in subparagraphs (a) through (j) of Item 4 of Schedule 13D. Subject to the Issuer’s Amended and Restated Bylaws (the “Bylaws”), each described in Item 6 of this Schedule 13D, and the Issuer’s Insider Trading Policy, the Reporting Person may from time to time buy or sell securities of the Issuer as appropriate for his personal circumstances.

From time to time, the Reporting Person, in his capacity as Chief Executive Officer of the Issuer and a member of the Issuer’s board of directors, may also acquire beneficial ownership of additional shares of Common Stock or other securities of the Issuer as compensation, by purchase or otherwise, including (a) pursuant to the exercise of options or vesting of any restricted stock units currently owned by the Reporting Person or (b) upon receipt from the Issuer of future compensatory equity incentive awards for which he qualifies, including, but not limited to, awards of Common Stock, options to purchase shares of Common Stock, and restricted stock units for Common Stock.

Except as described herein, the Reporting Person does not have any present plans or proposals that relate to or would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

The Reporting Person 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 Person’s evaluation of the Issuer’s business, prospects and financial condition, the market for such securities, other opportunities available to the Reporting Person, general economic conditions, stock market conditions and other factors. Depending upon the factors noted above, the Reporting Person may also decide to hold or dispose of all or part of his investments in securities of the Issuer, pursuant to 10b5-1 trading plans or otherwise, and/or enter into derivative transactions with institutional counterparties with respect to the Issuer’s securities.
