Pursuant to the Business Combination Agreement, upon consummation of the Business Combination (as defined below), the David N.

On June 3, 2025, the Reporting Person purchased in the open market 300 shares of Common Stock for $3.25 per share. The Reporting Person used personal funds to acquire such shares.

Business Combination On August 13, 2024 (the "Closing Date"), pursuant to a business combination agreement, dated as of October 4, 2023 (the "Business Combination Agreement"), by and among the Issuer (formerly known as Golden Arrow Merger Corp.), Beam Merger Sub, Inc., a direct wholly owned subsidiary of the Issuer ("Merger Sub"), and Bolt Threads, Inc. ("Legacy Bolt"), Merger Sub merged with and into Legacy Bolt (the "Merger" and, together with the other transactions contemplated by the Business Combination Agreement, the "Business Combination"), with Legacy Bolt surviving the Merger as a wholly owned subsidiary of the Issuer. The Issuer was renamed on the Closing Date to "Bolt Projects Holdings, Inc." As a result of the Business Combination, at the Closing Date, among other transactions, (i) each share of common stock of Legacy Bolt automatically converted into the right to receive shares of Common Stock based on an exchange ratio as described in the Business Combination Agreement, and (ii) each option to purchase common stock of Legacy Bolt, whether or not exercisable and whether or not vested, automatically converted into an option to purchase a number of shares of Common Stock in the manner set forth in the Business Combination Agreement. Registration Rights Agreement On the Closing Date, in connection with the consummation of the Business Combination and as contemplated by the Business Combination Agreement, certain stockholders of Golden Arrow Merger Corp. and certain securityholders of Legacy Bolt, including the Reporting Person, (collectively, the "Holders" and each, a "Holder") entered into an amended and restated registration rights and lock-up agreement (the "Registration Rights Agreement"). Pursuant to the terms of the Registration Rights Agreement, the Issuer was obligated to file a registration statement to register the resale of certain securities of the Issuer held by the Holders. In addition, subject to certain requirements and customary conditions, including with regard to the number of demand rights that may be exercised, the Holders may demand at any time or from time to time, to sell all or any portion of their registrable securities in an underwritten offering so long as the total offering price is reasonably expected to exceed $25 million. The Registration Rights Agreement also provides the Holders with "piggy-back" registration rights, subject to certain requirements and customary conditions. The Registration Rights Agreement further provided that the shares of Common Stock held by the Holders, including those beneficially owned by the Reporting Person, were to be locked-up for a period of six months following the Closing Date, subject to certain exceptions. The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, which is attached as an exhibit to this Schedule 13D and incorporated herein by reference.
