[Form 4] DT Midstream, Inc. Insider Trading Activity

Rhea-AI Filing Summary

DT Midstream (DTM) Form 4: EVP, General Counsel & Corporate Secretary Wendy Ellis reported two transactions on 08/02/2025.

• Exercise (Code M): 14,431 common shares acquired following the vesting of 12,083.5 restricted stock units; total direct holdings rose to 20,866 shares immediately after the exercise.
• Disposition (Code F): 7,728 shares sold at $105.61 per share.

After both actions, Ellis directly owns 13,138 DTM shares. No derivative securities remain outstanding. The filing indicates continued participation in the company’s dividend reinvestment plan and completes vesting of a multi-year RSU award (25% vested 2023, 25% 2024, 50% 2025).

Positive

• Net ownership increase of 6,703 shares suggests continued alignment between senior management and shareholders.

Negative

• Sale of 7,728 shares for about $0.82 million could be interpreted as partial profit-taking.

Insights

Securities Analyst

TL;DR: Insider nets +6,703 shares; sales offset part of RSU exercise—overall neutral signal.

The exercise converted all 12,083.5 remaining RSUs to common stock, boosting ownership by 14,431 shares. The concurrent sale of 7,728 shares at $105.61—likely for tax or liquidity—reduces the gross increase, leaving a net gain of 6,703 shares. Because Ellis remains a senior executive and keeps 13,138 shares, the filing is neither overtly bullish nor bearish. Dollar volume of the sale (~$0.82 m) is modest versus DTM’s average daily turnover, so market impact should be limited.
