Webster Roald Graham 4

What Happened

• Roald Graham, Vice President and Chief Accounting Officer of Allegro Microsystems (ALGM), had 4,277 shares withheld on May 16, 2026 to cover tax obligations arising from the vesting of restricted stock units and performance-vesting RSUs. The shares were valued at $43.10 each for a total of approximately $184,339. This was a tax-withholding disposition (routine), not an open-market sale or a purchase.

Context

• This is a routine tax-withholding event common when restricted stock units vest; the company retains (withholds) a portion of the vested shares to pay payroll/tax obligations. Such transactions are disposals for tax purposes but do not necessarily signal insider sentiment about the stock.
