Growth Broadens Across the Portfolio

Ecolab (NYSE:ECL) reported third-quarter net sales of USD 4.695 billion on Tuesday, up 13% from USD 4.165 billion, with organic sales growth accelerating to 7%. Volume growth improved to 2% despite continuing disruption in the Middle East, and pricing strengthened to 5%. Chairman and Chief Executive Christophe Beck described the quarter as an inflection point for performance.

Reported operating income rose 7% to USD 810.5 million, and adjusted operating income rose 14% to USD 893.4 million. Organic operating income grew 11%. The reported operating margin was 17.3% and reported gross margin 44.1%. Adjusted gross margin fell 70 basis points on the effect of acquisitions, though organic gross margin was stable as pricing offset higher commodity costs.

Reported net income fell 6% to USD 551.3 million, or USD 1.95 per diluted share against USD 2.05. Adjusted net income rose 4% to USD 615.4 million. Net interest expense rose USD 70 million on financing for the Ovivo Electronics and CoolIT acquisitions, and acquisition-related amortization and financing costs from CoolIT weighed about 10% on adjusted earnings per share growth.

Segments and Growth Engines

Global Water sales rose 20% on a fixed-currency basis to USD 2.480 billion, with acquisitions adding 11% and organic growth accelerating to 9%. Global High-Tech grew 63% organically on microelectronics and data center demand, and Food & Beverage accelerated to 8%. Light Water improved, and Heavy Water and Paper both returned to growth. Operating income in Global Water rose 24%, with the operating margin at 18.0% against 17.4%.

Global Institutional & Specialty sales rose 3% to USD 1.638 billion, operating income rose 8%, and the operating margin was 24.7% against 23.6% despite softer market trends. Life Sciences grew 17% organically, and Ecolab Digital sales rose 34% to USD 129 million on hardware subscriptions and software.

Management said Ovivo Electronics is projected to grow in the mid-teens and CoolIT to more than double against pre-acquisition sales this year, and that together they add about 2 percentage points to annual organic sales growth one year after closing.

Guidance and Management View

For the fourth quarter, management guided to adjusted diluted EPS of USD 2.13 to USD 2.23, up 2% to 7%. For 2026 it guided to USD 8.10 to USD 8.20, up 8% to 9%, and described the outlook as reflecting strong underlying performance and short-term CoolIT acquisition costs. The reported tax rate was 20.2% against 17.8%.

Looking to 2027, the chief executive said he expects organic sales growth at the upper end of the 5% to 7% target and an adjusted operating margin of 20%. He added that adjusted EPS growth accelerates in the second half of the year as acquisition effects are lapped, a path he tied to the company's 12% to 15% long-term adjusted EPS growth target.
