2026 ADJUSTED DILUTED EPS OUTLOOK: $8.10 - $8.20, +8% - 9%

THIRD QUARTER HIGHLIGHTS

•Strong execution drove broad-based acceleration, with reported sales growth of 13% and organic sales growth accelerating to 7%. Volume growth improved to 2% despite ongoing Middle East disruptions, while pricing accelerated to 5%.

•Growth in Ecolab's core businesses strengthened, led by accelerating growth in Food & Beverage and Light Water. Heavy Water and Paper both returned to solid growth.

•Ecolab's growth engines accelerated, driven by 63% organic sales growth in Global High-Tech and 17% organic sales growth in Life Sciences. Ovivo Electronics and CoolIT also performed exceptionally well and, one year after close, are expected to contribute approximately 2 percentage points to Ecolab's annual organic sales growth.

•Reported operating income margin 17.3%. Organic operating income margin 19.6%, +70 bps. Reported gross margin 44.1%. As expected, adjusted gross margin declined 70 bps due to the impact of M&A; excluding this, organic gross margin was stable as accelerating pricing offset rising commodity costs.

•Reported diluted EPS $1.95. Adjusted diluted EPS $2.18, +5%, including an approximate 10% headwind from CoolIT acquisition-related amortization and financing costs.

•4Q 2026: Expect adjusted diluted EPS in the $2.13 to $2.23 range, +2% to 7%.

CEO Comment

Christophe Beck, Ecolab’s chairman, president and chief executive officer, said, “Third quarter results marked an inflection point in Ecolab's performance. Exceptional execution drove accelerating sales growth, margin expansion and double-digit adjusted operating income growth. Volume growth accelerated to 2% despite ongoing disruptions in the Middle East. As expected, pricing strengthened to 5% as we leveraged total value delivered to mitigate higher commodity costs while improving customer performance. This disciplined execution allowed us to stabilize our organic gross margin.

“The breadth of our performance makes these results even more encouraging. Growth across our core businesses strengthened, led by accelerating growth in Food & Beverage and Light Water, alongside consistent growth in Institutional & Specialty despite softer market trends. Performance in Paper and Heavy Water also improved, with both businesses returning to solid growth. Across these core businesses, our One Ecolab growth initiative is helping deliver greater customer value and share gains for Ecolab.

“Our growth engines continued to rapidly accelerate, with very strong performance across all businesses. Global High-Tech, our largest growth engine, significantly accelerated, growing 63% organically. Our recent acquisitions in this business, Ovivo Electronics and CoolIT, are also performing exceptionally well. This year, we expect Ovivo Electronics to grow mid-teens and CoolIT to more than double, compared with pre-acquisition sales. Together, these acquisitions are expected to add two percentage points to Ecolab's annual organic sales growth one year after close with increasing margins. Our differentiated water circularity solutions for microelectronics and next-gen liquid cooling technologies for AI data centers position Ecolab extremely well to capitalize on significant long-term growth opportunities.

“We are entering 2027 with momentum and confidence in our ability to deliver another very strong year. We expect organic sales to grow at the upper end of our 5% to 7% target and Ecolab's adjusted operating income margin to reach 20%. Adjusted EPS growth is expected to accelerate in the second half of the year as we lap M&A transaction impacts and operating performance continues to accelerate. This provides a clear path to meet or exceed our long-term adjusted EPS growth target of 12% to 15% in 2027. We have never been better positioned to deliver exceptional value for customers and shareholder
