German Christopher Paul 4

What Happened

• German Christopher Paul, Corporate Controller & CAO of Rhythm Pharmaceuticals (RYTM), had restricted stock units (RSUs) convert into 3,613 shares on Feb 1, 2026. As part of the settlement, 1,138 shares were withheld to cover withholding taxes, valued at approximately $124,031.
• The filing shows two separate conversion entries of 1,806 and 1,807 shares (reported as dispositions at $0) consistent with conversion/settlement of two RSU grants. These are reporting mechanics of vested RSUs, not open-market sales.

Key Details

• Transaction date: Feb 1, 2026; Form 4 filed Feb 3, 2026 (timely filing).
• Withheld-for-taxes detail: 1,138 shares withheld at $108.99 per share for $124,031 (code F — tax withholding).
• Conversion entries: 3,613 shares reported as acquired via derivative conversion (code M); two conversion/disposition lines of 1,806 and 1,807 shares at $0 reflect settlement mechanics.
• Shares owned after transaction: not specified in the excerpted filing.
• Footnotes: F1–F5 confirm these were RSUs (one RSU grant vests 25% on Feb 16, 2025 and then annually; another vests 25% on Feb 1 of 2026–2029). F2 notes 36 shares include purchases under the company ESPP; F3 explains shares withheld were for taxes.

Context

• This was compensation-related (RSU vesting and net share settlement), not an open-market buy or sell. Withholdings to satisfy tax liabilities are routine following RSU vesting and do not necessarily indicate insider sentiment.
