RODRIGUEZ RICARDO C. 4/A

What Happened

• Ricardo C. Rodriguez, Chief Financial Officer of Amprius Technologies, received an award of 150,000 restricted stock units (RSUs) reported as an acquisition on 2026-03-04. The grant is reported at $0.00 per share (no cash paid at grant); fair market value at vesting will determine economic value. This filing is an amendment to correct the RSU vesting schedule.

Key Details

• Transaction date: March 4, 2026; Form 4/A filed March 13, 2026 (amendment to original filing).
• Transaction type/code: A = Award/Grant.
• Shares granted: 150,000 RSUs; reported acquisition price: $0.00 (total $0 at grant).
• Post-transaction ownership: Not stated in the information provided.
• Footnote: Amended filing corrects vesting schedule — 3/16ths vest on Nov 20, 2026, then quarterly on Feb 20, May 20, Aug 20 and Nov 20 thereafter, subject to continued service, until fully vested on Feb 20, 2030.
• No tax withholding, sale, or 10b5-1 plan noted in this excerpt.

Context

• RSU awards are not immediate cash or open-market purchases; value is realized only as units vest and are converted to shares (or settled in cash per plan). This is an amended disclosure to clarify vesting timing rather than a new economic transaction.
