Ecolab (ECL) Director Suzanne Vautrinot Exercises Options, Sells Shares

What Happened

Suzanne M. Vautrinot, a director of Ecolab Inc., exercised 2,000 stock options on 2026-05-22 (exercise price shown $125.67) to acquire 2,000 shares. To cover the exercise/tax obligation, 996 shares were surrendered/withheld (reported as a disposal under tax-withholding). The remaining 1,004 shares were sold in the open market on 2026-05-27 at $264.98 per share for proceeds of $266,040. This sequence is a cashless exercise followed by an open-market sale — a routine disposition rather than a new cash investment.

Context

This is an option exercise with immediate partial sale (cashless exercise). The withholding of shares to cover taxes/exercise costs is common and explains why only a portion of the exercised shares were sold in the market.
The transactions are routine director activity and should be viewed as reporting of personal liquidity from exercised options rather than a clear buy/sell signal about company prospects. Transaction codes: M = option exercise/conversion, F = tax/withholding, S = open-market sale.
