What Happened

• Jeffrey A. Jewell, Executive Vice President and Chief Financial Officer of DT Midstream (DTM), had restricted stock units (RSUs) convert/vest on May 4, 2026.

Of those, 16,109 shares were withheld to satisfy tax withholding (reported as a disposition) at a per-share valuation of $138.70, generating $2,234,318 in tax payment. The remaining 13,209.2 shares were issued to him (reported as the conversion of a derivative with $0 cash proceeds).

Context

• This appears to be a routine RSU vesting and settlement event rather than an open-market purchase or sale motivated by investment views. The withholding of 16,109 shares to cover tax obligations is a common cashless settlement mechanism for vested equity awards. The filing was submitted within the standard two‑business‑day window and is timely.
