Rowland Sandra E. 4

What Happened

• Sandra E. Rowland, a director of Amentum Holdings, had restricted stock units (RSUs) that vested on February 6, 2026, resulting in an award/acquisition of 5,062 shares of AMTM common stock at $0.00.
• The Form 4 also records exercise/conversion of 11,564 derivative units (code M) and a corresponding disposition of 11,564 derivative shares; all reported transactions show $0.00 cash consideration.
• These entries reflect issuance/settlement of equity tied to RSUs rather than an open-market buy or sale.

Key Details

• Transaction date: February 6, 2026; Form 4 filed February 10, 2026 (filing appears timely).
• Award: 5,062 shares acquired at $0.00 (vested RSUs).
• Derivative activity: 11,564 shares shown as exercised/converted (code M) and 11,564 shares shown as disposed (recorded at $0.00); filing does not state the reason for the disposition.
• Footnotes: RSUs represent a contingent right to one share each and vested on February 6, 2026.
• Shares owned after the transactions: not specified in the provided filing data.
• No 10b5‑1 plan, tax‑withholding method, or late-filing indicator is disclosed in the summary provided.

Context

• This is an award/vesting event (not an open‑market purchase or sale). Vesting of RSUs is common compensation for executives and directors and does not by itself indicate a buy/sell trading signal.
• The reported exercise/conversion and matching disposition of derivative units may reflect internal settlement mechanics; the filing does not provide further detail (e.g., tax withholding or net settlement).
