NOWELL LIONEL L III 4

What Happened

• Lionel L. Nowell III, a member of Ecolab Inc.'s board of directors, was granted a derivative award on 2026-05-15 covering 732 shares. The Form 4 reports the acquisition as a derivative grant (price $0.00 at grant), meaning no cash was paid at the time of grant and no shares were transferred immediately.

Key Details

• Transaction date: 2026-05-15; Form 4 filed: 2026-05-19 (filed within the standard two-business-day window).
• Reported consideration at grant: $0.00 (derivative award / option).
• Shares owned after the transaction: not specified in the provided filing.
• Footnote: the option vests cumulatively — 25% at the end of each of the first three three-month periods after grant, with the remainder vesting at the end of the fourth three-month period or the company’s next annual meeting (whichever is earlier). If a Change in Control occurs (as defined in the company plan), the option becomes immediately exercisable in full. The filing’s "Date Exercisable" reflects the first vesting date.

Context

• This is a stock-option style grant (a derivative award). No shares were sold or purchased on the open market as part of this filing; the award gives the holder the right to acquire shares in the future subject to vesting and exercise terms. Such grants are common for non-employee directors and represent compensation rather than an immediate investment decision.
