Jiang Wei 4

What Happened
Jiang Wei, a director of Waters Corp (WAT), received equity awards on February 25, 2026: 23 restricted shares of common stock and 57 derivative units (a stock option award). Both grants show $0 cash paid (awards rather than purchases); combined they represent 80 shares/units, with the restricted shares and the option award scheduled to vest/become exercisable on February 9, 2027.

Key Details

• Transaction date: 2026-02-25; filing date (Form 4): 2026-02-27 (timely, two days after the transaction).
• Grant amounts & price: 23 restricted shares @ $0.00 (acquired); 57 derivative stock-option units @ $0.00 (acquired).
• Total units granted: 80 (23 restricted shares + 57 option units).
• Shares owned after transaction: not specified in the supplied report.
• Footnotes: F1 — the 23 restricted shares are subject to restrictions that lapse 100% on Feb 9, 2027. F2 — all shares underlying the 57-share stock option will vest and become exercisable on Feb 9, 2027.
• No sale occurred and no cash was exchanged for these awards (code A = award/grant).

Context
These were equity awards, not open-market purchases or sales. The option award will require exercise to convert to shares once vested (per F2); the restricted shares will simply lapse their restrictions on the stated vesting date (per F1). Awards to directors are common as compensation and do not by themselves signal buying or selling intent.
