KURTZWEIL JOHN T 4

What Happened
John T. Kurtzweil, a director of Axcelis Technologies, was granted 1,440 restricted stock units (RSUs) on May 15, 2026. The grant price was $0.00 (award), so the reported acquisition value is $0. These RSUs are issuable shares that will convert into common stock if the vesting conditions are met.

Context
RSUs are a form of equity compensation: they represent a promise to deliver shares in the future if vesting conditions are met and do not require an upfront cash purchase. Because these units vest contingent on continued service, they are typical director compensation and do not necessarily indicate a buy/sell signal by the insider.
