Roberts Mark Lawrence 4

What Happened Mark Roberts, a director of Compass Minerals International, received director compensation in the form of equity awards in December 2025. The filing reports two grants: 1,348 restricted stock units (RSUs) on 2025-12-18 and 196 common stock units on 2025-12-31, for a total of 1,544 units. Each grant is reported at $0.00 per share (standard for awards), so the transaction value on the Form 4 is $0.

Key Details

• Transaction dates and types: 2025-12-18 — Award (derivative/RSU) of 1,348 shares; 2025-12-31 — Award of 196 common stock units. Both reported as code "A" (award/grant).
• Price: $0.00 per share as reported (typical for compensation grants).
• Shares owned after transaction: Not specified in the excerpt provided (not reported here).
• Footnotes: F1 = common stock units granted for director service; F2 = annual RSU grant that will vest on the first anniversary of the grant date.
• Filing timeliness: Form filed 2026-01-29 for transactions in Dec 2025 — this is beyond the typical 2-business-day Form 4 reporting window, so the filing appears late.

Context

• These grants are compensation for board service, not open-market purchases or sales; such awards are routine and do not by themselves indicate the director is buying or selling stock based on a view of the company.
• The 1,348 RSUs are derivative awards that will convert to shares upon vesting (one year after grant per F2). The 196 common stock units appear to be immediate stock-unit awards per F1.
