Item 1.01 Entry into Material Definitive Agreement
On May 6, 2026, Amprius Technologies, Inc. (the “Company”) entered into Warrant Exchange Agreements (the “Exchange Agreements”) with certain institutional holders (the “Public Warrant Holders”) of the Company’s public warrants (the “Exchange Public Warrants”), each of which is exercisable to purchase one share of common stock of the Company, par value $0.0001 per share (“Common Stock”), at an exercise price of $11.50 (the “Exercise Price”) per existing Exchange Public Warrant. Pursuant to the Exchange Agreements, the Public Warrant Holders agreed to exchange an aggregate of 7,128,458 Exchange Public Warrants for shares of Common Stock (the “Exchange Shares”).
Pursuant to the terms of the Exchange Agreements, Public Warrant Holders will receive, for the Exchange Public Warrants exchanged, a number of Exchange Shares equal to the product of (i) the number of Exchange Public Warrants so surrendered multiplied by (ii) the quotient of (a) the sum of (x) the average volume-weighted average price of the Common Stock over a four day consecutive trading period (the “Average VWAP”), (y) plus $0.35, (z) minus the Exercise Price, divided by (b) the Average VWAP.
The closing of the exchanges of the Exchange Public Warrants for Exchange Shares is expected to occur on May 18, 2026, and is subject to customary closing conditions.
The Exchange Agreements contain customary representations, warranties, covenants, and other obligations of the parties. The representations, warranties and covenants contained in the Exchange Agreements were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties.
The above summary of the Exchange Agreements does not purport to be complete and is qualified in its entirety to the full text of the form of Exchange Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K.
Item 3.02 Unregistered Sales of Equity Securities
The disclosures set forth above under Item 1.01 are incorporated herein by reference. The issuance by the Company of the Exchange Shares in exchange for the surrender and cancellation of the Exchange Public Warrants is being made in reliance on Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), in reliance in part on the representations, warranties and covenants made by the Public Warrant Holders. The Exchange Shares to be issued pursuant to the Exchange Agreements may not be re-offered or sold in the United States absent an effective registration statement or an exemption from the registration requirements under applicable federal and state securities laws.
