Nichols Christian Todd 4

What Happened

• Christian Todd Nichols, SVP & Chief Commercial Officer of Alkermes (ALKS), had 5,410 restricted stock units (RSUs convert/settle into ordinary shares) on 2026-02-26. Of those, 2,403 shares were withheld to cover taxes at $30.73 per share (total tax withholding = $73,844), leaving a net issuance of 3,007 shares to Nichols.
• The Form 4 reports both the conversion/exercise of the derivative award (code M) and the tax withholding/disposition of shares (code F). This is not an open-market sale or purchase by the insider but the routine vesting/settlement of an equity award.

Context

• This transaction reflects routine RSU settlement and tax withholding, not an open-market trade. The code M indicates conversion/settlement of a derivative award (RSU), and code F reflects shares surrendered/withheld to satisfy tax obligations. Such withholding is common when awards vest and does not necessarily signal insider sentiment about the stock.
