Cox Melissa 4

What Happened

• Melissa Cox, Executive Vice President & Chief Administrative Officer of DT Midstream (DTM), had restricted stock units convert/vest into company shares on February 1, 2026. The filing reports 4,455.83 shares arising from exercises/conversions of derivatives (M).
• Of those, 1,179 shares were withheld to satisfy tax obligations at a withholding price of $126.02 per share, totaling $148,578 (transaction code F). The filing also shows 2,094 shares reported as an exercise/conversion (M) with $0 proceeds; the report does not provide further detail on that $0 amount.

Key Details

• Transaction date: February 1, 2026; SEC filing date: February 3, 2026 (timely).
• Reported conversions/exercises (M): 2,361.83 shares (acquired) and 2,094 shares (listed as disposed with $0 proceeds); total shown = 4,455.83 shares.
• Tax withholding (F): 1,179 shares withheld @ $126.02 = $148,578.
• Footnotes: F2 notes each restricted stock unit equals one share; F3 confirms the RSU vested on Feb 1, 2026; F1 notes inclusion of shares acquired under the issuer's dividend reinvestment plan where applicable.
• Shares owned after the transaction are not disclosed in the provided filing.

Context

• This was not an open-market purchase or sale by the insider but the conversion/vesting of restricted stock units and the withholding of shares to cover taxes — a routine administrative outcome of RSU vesting.
• The line showing 2,094 shares with $0 proceeds appears in the filing but is not explained; it does not reflect an open-market sale with cash proceeds.
• No late-filing flag was indicated; the report was filed two days after the transaction date.
