What changed: Exhibit 10.1 to an 8-K of Amprius Technologies, Inc.: a Second Amendment to Industrial Lease dated August 7, 2026 with Los Altos Fields, LLC covering approximately 51,000 rentable square feet at 1000–1180 Page Avenue, Fremont, California. The lease had been scheduled to expire June 30, 2027; the term is extended 84 months from a July 1, 2027 commencement to a new expiration of June 30, 2034. All previous extension options are deleted and replaced with two five-year options at then-current fair market rent, floored at the rent payable in the last month of the extended term. Why it matters: The company has committed to this facility for seven additional years beyond the prior June 30, 2027 expiry, at a rent schedule fixed through June 2034. The two five-year renewal options are unexercised.
What changed: Amprius Technologies (formerly Kensington Capital Acquisition Corp. IV) filed its Q2 2026 10-Q showing revenue of $34.0M for Q2 and $62.6M for 1H 2026, up 126% and 137% YoY respectively, with net loss narrowing to $3.2M in Q2 from $6.4M prior year. The company terminated its Brighton, Colorado lease for a $20.0M one-time payment and conducted a cashless exchange of 7.1M public warrants for 2.7M shares, reducing outstanding warrants from 18.8M to 10.5M. Why it matters: Revenue growth is accelerating driven by SiCore battery sales, and gross margin improved to 27% from 9% YoY, suggesting improving operating leverage. The warrant exchange reduces future dilution and the lease termination eliminates a significant non-cash lease obligation ($33.2M liability derecognized), streamlining the balance sheet.
What changed: 8-K of Amprius Technologies, Inc. Item 2.02 (results of operations and financial condition): on August 4, 2026 the Company announced its business and financial results for the fiscal second quarter ended June 30, 2026, with the earnings release furnished as Exhibit 99.1. The Item 2.02 information and Exhibit 99.1 are not deemed filed for Section 18 purposes nor incorporated by reference. The report adds that the contents of any website or hyperlink mentioned in the release are informational only and not part of it. Signed by CFO Ricardo C. Rodriguez. Why it matters: Routine quarterly earnings furnishing; the report states no figure. Its one distinctive term is the express disclaimer of hyperlinked website content, which narrows what the release itself is asserting.
What changed: Amprius Technologies, Inc., successor to Kensington Capital Acquisition Corp. IV, noticed its annual meeting for June 11, 2026 at 10:00 am local time by live audio webcast, record date April 13, 2026, with items including auditor ratification for the fiscal year ending December 31, 2026. Thomas M. Stepien was appointed Chief Executive Officer effective January 1, 2026 after Dr. Kang Sun stepped down as CEO effective December 31, 2025 and became Executive Advisor. Why it matters: The warrant structure is the investor-relevant detail carried over from the Kensington IV SPAC: PIPE Warrants sit outside any exchange listing and cannot be called until the stock averages above $20.00, versus $18.00 for public warrants, so that block stays outstanding as dilution far longer than the listed paper. The CEO handover effective January 1, 2026 puts a new executive in place for the first full year under those terms.
