EXPLANATORY NOTE

DEREGISTRATION OF SECURITIES

These Post-Effective Amendments (the "Post-Effective Amendments") of Bolt Projects Holdings, Inc. (the "Company" or "Bolt") relate to the Company's following Registration Statements on Form S-8 (collectively, the "Registration Statements") filed with the Securities and Exchange Commission ("SEC") and are being filed to deregister all securities that were registered for issuance under the Registration Statements and that remain unsold thereafter:

1. Registration Statement on Form S-8 (File No. 333-283288) filed November 18, 2024.

2. Registration Statement on Form S-8 (File No. 333-286430) filed on April 7, 2025.

On December 31, 2025, Bolt received written notification from the Nasdaq Hearings Panel (the "Panel") of the Nasdaq Stock Market LLC ("Nasdaq") stating that, due to the Company's having not met the terms of the Panel's September 30, 2025 decision that the Company demonstrate compliance with the minimum equity standard requirement under Nasdaq Listing Rule 5550(b)(1) by December 31, 2025, the Company's securities will be delisted from Nasdaq, and trading will be suspended at the open of trading on January 5, 2026. Following suspension of trading on Nasdaq, the Company common stock started trading on the OTC Pink Market under the trading symbol, "BSLK" and its public warrants under the trading symbol "BSLKW."

The Company determined not to appeal the Panel's decision and, on March 2, 2026, voluntarily filed a Form 25 with the SEC to delist the securities and warrants from Nasdaq.

Pursuant to the undertaking made by the Registrant in the Registration Statements to remove from registration by means of a post-effective amendment any of the securities that had been registered for issuance that remain unsold at the termination of the respective offering, the Registrant is filing these Post-Effective Amendments to terminate the effectiveness of such Registration Statements and to deregister, as of the effectiveness of these Post-Effective Amendments, any and all securities registered thereunder that remain unsold as of the effectiveness date. As a result of this deregistration and upon the effectiveness of these Post-Effective Amendments, no securities of the Company will remain registered pursuant to the Registration Statements.
