About the company

Amprius Technologies Inc

Amprius Technologies Inc is engaged in the production of silicon anodes for high-energy-density lithium-ion batteries. The company develops, manufactures and markets lithium-ion batteries for mobility applications, including the aviation, electric vehicle (EV) and light electric vehicle (LEV) industries. The company's batteries are used for existing and emerging aviation applications, including unmanned aerial systems, such as drones and high-altitude pseudo satellites. Its silicon anodes are a direct drop-in replacement of the graphite anode in traditional lithium-ion batteries, and its manufacturing processes leverage the manufacturing processes for conventional lithium-ion batteries and the related supply chain.

Market action

A concise summary of the latest filing, transaction, or market-moving item.

Amprius Technologies, Inc. reported the results of its 2026 annual meeting of stockholders, held on June 11, 2026. The company’s stockholders voted on two matters: the election of two directors and the ratification of the company’s independent auditor for fiscal 2026. In the director election, Kathleen Bayless and Thomas M. Stepien were elected to serve as directors until the company’s 2029 annual meeting of stockholders, or until their successors are duly elected and qualified. Bayless received 50,367,535 votes in favor and 20,194,821 votes withheld, with 26,519,800 broker non-votes reported. Stepien received 53,880,993 votes in favor and 16,681,363 votes withheld; the filing’s table indicates broker non-votes applied to the director-election proposal, though the extracted text does not separately repeat the broker non-vote figure on his line. Stockholders also ratified the appointment of Deloitte & Touche LLP as Amprius Technologies’ independent registered public accounting firm for the fiscal year ending December 31, 2026. The auditor ratification received 96,014,911 votes for, 85,854 votes against and 981,391 abstentions. The filing was made under Item 5.07, “Submission of Matters to a Vote of Security Holders,” and confirms that both proposals presented at the annual meeting passed. No securities issuance, insider transaction, merger, financing, executive-compensation award or other transactional corporate action was reported in this filing.
