Ecolab (ECL) Director Tracy B. McKibben Exercises Options, Sells Shares

What Happened

Tracy B. McKibben, a director of Ecolab Inc. (ECL), exercised 2,300 stock options on Feb 25, 2026 at a strike price of $115.08 per share (total outlay $264,673) and then sold 1,265 of the resulting shares in an open-market transaction at $308.66 per share (total proceeds $390,455). The Form 4 also records the disposition of the derivative/options instrument (2,300) at $0.00, reflecting the exercise/conversion of the options.

Key Details

Transaction date: 2026-02-25; Form 4 filed 2026-02-26 (timely).
Option exercise: 2,300 shares @ $115.08 = $264,673 (code M, Acquired).
Open-market sale: 1,265 shares @ $308.66 = $390,455 (code S, Disposed).
Derivative conversion: 2,300 option units shown disposed at $0.00 (reflects exercise).
Shares retained from this action: 2,300 exercised − 1,265 sold = 1,035 shares kept from the exercise.
Footnote: the options vest cumulatively (25% after each three‑month period for the first three periods, remainder after the fourth 3‑month period); options become fully exercisable upon a defined Change in Control per the plan (see footnote F1).
Filing timeliness: No late-filing indicator; filed the next day.

Context

This is an option exercise followed by a partial open-market sale — a common pattern where an insider exercises options and sells some shares (often to cover the exercise cost or taxes) while retaining the remainder. The filing is factual and does not state the insider’s motivation.
