DEALY RICHARD P 4

What Happened Richard Dealy, a director of Compass Minerals International, reported derivative activity on March 5, 2026. The Form 4 shows an exercise/conversion (code M) for 11,905 shares (reported as both acquired and disposed, $0 price/value in the filing) and a separate grant/award (code A) of 5,032 restricted stock units (RSUs) at $0. The filing was submitted on March 9, 2026.

Key Details

• Transaction date: 2026-03-05; Form 4 filed: 2026-03-09.
• Exercise/Conversion (M): 11,905 shares reported as acquired and also reported as disposed (both at $0 as shown on the Form 4).
• Grant/Award (A): 5,032 RSUs granted at $0. Footnote F1: these RSUs are an annual director grant that vests the earlier of (a) the day before the issuer’s next annual meeting (if that meeting is at least 50 weeks from grant) or (b) one year from the grant date.
• Shares owned after the transaction: not specified in the supplied filing details.
• Timeliness: The Form 4 was filed four days after the reported transactions; Form 4s are generally due within two business days, so this filing occurred after the usual two-business-day window.

Context

• Code M covers exercise or conversion of a derivative; the Form shows the same 11,905 shares both acquired and disposed on the same day at $0, which on Form 4s can reflect a conversion/settlement pattern (for example, an exercise followed by a disposition or net settlement). The filing does not provide cash values for these reported lines.
• The 5,032-item line is a standard annual RSU award for director compensation with a defined vesting schedule (see footnote F1). These types of grants are routine director compensation and do not by themselves indicate personal market views.
