KIERNAN JOHN P 4/A

What Happened
John P. Kiernan, Chief Financial Officer of Veeco Instruments Inc. (VECO), is reported to have acquired 42,500 shares by way of a derivative transaction (code M) on 2026-03-10 at an acquisition price of $0.00. The filing is an amendment; footnotes clarify these are restricted stock units (RSUs) granted under Veeco’s 2019 Stock Incentive Plan rather than a cash purchase or immediate sale. No cash value was paid at grant.

Key Details

• Transaction date: March 10, 2026 (reported originally on Form 4 filed March 12, 2026; amended Form 4 filed May 8, 2026).
• Reported amount: 42,500 RSUs; acquisition price reported as $0.00 (award).
• Vesting: RSUs vest 1/3 on each of the first, second and third anniversaries of the grant date; vested shares will be delivered on each vesting date (per footnotes).
• Filing note: This is an amended filing made voluntarily to move the grant to Table II (unvested awards) and to revise the reported beneficial ownership and unvested RSU totals.
• Shares owned after transaction: The amended filing adjusts totals in the tables; the exact post-transaction beneficial ownership count is not provided in the excerpt.

Context
This transaction represents an equity award (compensation/retention RSUs) rather than an open-market purchase or sale, so it is not a direct market-timing signal. The grant is subject to standard vesting restrictions; there is no indication in the filing that any shares were sold immediately.
