Peer group, and who names Amprius Technologies as a peer
Companies that benchmark against AMPX
2 companies name AMPX as a compensation peer
- Enovix CorpENVXFY2025
- Lightwave Logic, Inc.LWLGFY2025
Each company listed discloses AMPX in its own benchmarking peer group, as disclosed in each company's most recent proxy statement within the last two proxy seasons. Two companies are therefore absent by design: one that named AMPX in an earlier year and no longer does, and one whose own most recent disclosure is older than the last two seasons.
Chief executive pay against the peer group
Most recent fiscal-year chief executive compensation at each disclosed peer, taken from that company’s own proxy statement.

Each peer’s compensation is from its most recently filed proxy; fiscal years differ by company. Each peer’s figures come from its own filings; the subject company is highlighted. Peers whose chief executive compensation is outside our coverage universe are stated as such, never left blank.
