Ecolab Inc.
A maker of water treatment, hygiene, and infection-prevention products, Ecolab serves hotels, restaurants, hospitals, and heavy industry with cleaning chemicals, pest control, and purification systems under brands like Purolite and Bioquell. It began in 1923 when salesman Merritt J. Osborn, inspired by a stain on a hotel carpet, started mixing rug cleaners in a St. Paul basement. A 2011 merger with Nalco turned the company into one of the world's largest water-technology firms.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -2.17M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
