Ecolab (ECL) director Eric Mark Green awarded 732 new stock options

Rhea-AI Filing Summary

Ecolab Inc. director Eric Mark Green received a new stock option grant as part of his board compensation. He was awarded options for 732 shares of common stock at an exercise price of $247.7000 per share, with no cash paid at grant.
