Ecolab Inc. completed a $5 billion investment-grade bond offering. These funds will finance the $4.75 billion acquisition of liquid cooling specialist CoolIT Systems.
The debt sale included four tranches of fixed-rate senior notes. These notes mature between 2029 and 2036. Strong institutional demand and tight spreads supported the offering during a high-volume week for corporate debt alongside Merck.
The transaction facilitates Ecolab’s strategic expansion into thermal management for AI-driven data centers. Shares rose 0.62% to close at $250.18 following the announcement. The stock has declined more than 9% over the past month.
