Dieter David 4

What Happened
Dieter David, Executive Vice President & General Counsel of Collegium Pharmaceutical, had 8,840 shares disposed (withheld) to satisfy applicable withholding taxes upon the vesting of restricted stock units. The withholding occurred on 2026-03-17 at a reported per-share value of $35.72, for a total value of approximately $315,765. This was a tax-withholding/net settlement of vested RSUs — not an open-market sale.

• Footnote: F1 — "Shares withheld by the Issuer to satisfy applicable withholding taxes upon the vesting of restricted stock units."

Context
Withholding shares to cover taxes on vested RSUs is a routine, administrative action (a net settlement) and generally does not signal the insider buying or selling stock in the open market. It reduces outstanding shares owned by the insider but is done to meet tax obligations rather than to realize gains. The later filing date may reflect a reporting delay; repeated late filings can be noteworthy, but a single late Form 4 is typically a reporting/timing issue rather than a trading signal.
