Context

This was primarily a vesting/conversion of performance-based RSUs rather than an open-market buy or sale. The surrender of shares was for tax withholding (a routine, non-discretionary action), not an active sale for cash gain. The ESPP purchase is a routine employee purchase and represents an out-of-pocket buy (small net purchase). For retail investors, such vesting events indicate compensation realization rather than a deliberate market trade for investment purposes.

Each PRSU represented the contingent right to receive one share of Veeco common stock. The award, if earned, could range from 50% to 200% of the granted PRSUs based on the achievement of the Criteria. The common stock award reflected in this filing represents achievement at the 172.5% level, which was realized.
