Atmus Filtration (ATMU) CEO Stephanie Disher Sells 25,652 Shares

What Happened

Stephanie Disher, CEO of Atmus Filtration Technologies Inc. (ATMU), reported an open-market sale of 25,652 shares on 2026-06-01 at $45.25 per share, resulting in proceeds of approximately $1,160,676. This was a sale (code S) tied to shares that vested; the filing indicates the sale was to satisfy the reporting person's tax withholding obligation rather than an independent market-timing purchase.

Key Details

• Transaction date and price: 2026-06-01 — 25,652 shares sold at $45.25 each.
• Total proceeds: $1,160,676.
• Shares owned after transaction: Not specified in the provided filing.
• Footnote: F1 — sale reflects shares sold upon vesting of the first half of a launch grant award to pay tax withholding obligations.
• Filing: Report filed 2026-06-02 (one day after the transaction date), which appears to be timely.

Context

• This sale was to cover tax withholding on vested restricted stock (per the footnote), a common administrative transaction that does not necessarily indicate the insider's view on the company’s stock.
• Sales are generally less informative than purchases about insider sentiment; here the filing points to a routine tax-related disposition rather than a discretionary cash-out.
