Ecolab Delivers Accelerated Sales Growth and Double-Digit EPS Growth; Reported Diluted EPS $1.90; Adjusted Diluted EPS $2.09, +11%; Raises 2026 Adjusted Diluted EPS Outlook: $8.05 - $8.25, +7% - 10%

Ecolab Inc. (NYSE: ECL):

SECOND QUARTER HIGHLIGHTS

• Ecolab delivered strong performance across the business. Accelerated organic sales growth, driven by good volume growth despite Middle East disruptions and by improved pricing, as well as strong productivity, more than offset rising commodity costs.
• Reported sales $4.4 billion, +10%. Organic sales growth accelerated to +5%. Growth in Ecolab's core businesses improved, led by accelerating growth in Food & Beverage, Institutional, and Light Water. Ecolab's growth engines continued to grow strong double-digits, led by accelerating growth in Global High-Tech and Life Sciences.
• Reported operating income margin 17.2%. Organic operating income margin 18.8%, +40 bps. Reported gross margin 44.1%. As expected, adjusted gross margin declined 60 bps due to the impact of the Ovivo Electronics acquisition; excluding this impact, organic gross margin was stable as strong pricing offset rising commodity costs.
• Reported diluted EPS $1.90, +3%. Adjusted diluted EPS $2.09, +11%.

RAISES 2026 OUTLOOK

• 2026: Expect adjusted diluted EPS in the $8.05 to $8.25 range, +7% to 10%, higher than prior expectations of $8.03 to $8.23.
• 3Q 2026: Expect adjusted diluted EPS in the $2.13 to $2.23 range, +3% to 8%.
• These ranges reflect strong underlying performance and a short-term impact from non-cash amortization and financing costs of the CoolIT acquisition.

CEO Comment

Christophe Beck, Ecolab’s chairman, president and chief executive officer, said, “We delivered another quarter of double-digit EPS growth, driven by strong execution across the company which produced accelerating organic sales growth, a stable organic gross margin excluding the impact from Ovivo Electronics, and strong productivity. Reported volume grew 1%, despite a nearly 1% headwind from customer operations disrupted by the conflict in the Middle East, while underlying volume growth strengthened. Pricing improved to 4%, reflecting the early benefits of our energy surcharge implementation, which helped to mitigate the impact of rising commodity costs. This strong performance demonstrates the durability of our growth model and the power of our global team to deliver for our customers no matter what.

“As we indicated last quarter, the second quarter was a transition period. We entered the quarter with higher commodity costs and little benefit from our energy surcharge. Our team executed extremely well, implementing the surcharge globally, strengthening pricing throughout the quarter, continuing to grow volumes, and stabilizing organic gross margin in just one quarter. With total pricing in the second half expected to be in the 5% to 6% range, we are very well positioned to offset higher commodity costs and deliver strong underlying performance.

“Growth in our core businesses improved as we advanced our One Ecolab growth strategy to continue to gain share. Food & Beverage, Institutional, and Light Water accelerated, while performance in Heavy Water and Paper improved. Our growth engines continued to rapidly scale, led by 29% growth in Global High-Tech and 15% growth in Life Sciences. Our acquisition of Ovivo Electronics is also performing very well, and we continue to expect it to grow mid-teens this year versus pre-acquisition sales.

“The recent close of our acquisition of CoolIT further strengthens our Global High-Tech growth engine, extending our leadership in water technologies, research, and services into the rapidly growing AI infrastructure market. CoolIT's growth momentum continues to strengthen, with pre-acquisition sales up more than 100% in the first half. Our Global High-Tech platform is now approaching $1.5 billion in annualized sales, and we expect it to grow to $4 billion in sales by 2030, with operating income margins of 25%. This business is now our largest growth engine and is expected to contribute more than two percentage points to Ecolab's annual sales growth one year after acquisition with increasing margins.

“Looking ahead, we expect continued momentum, supported by very strong performance in our growth engines, ongoing share gains from One Ecolab, accelerating pricing, and improved productivity. We have never been better positioned to deliver long-term organic sales growth of 5% to 7%, expand operating income margins well beyond 20%, and continue strengthening our EPS growth algorithm.”

Second Quarter 2026 Consolidated Results

Ecolab’s second quarter reported sales increased 10% and organic sales growth accelerated to 5%. Ecolab Digital sales increased 27% to $121 million, with strong growth across both enabling hardware subscriptions and software.

Second quarter 2026 reported operating income increased 7% including the impact of special gains and charges. Adjusted operating income increased 10%, as accelerating pricing more than offset higher commodity costs and growth-oriented investments in the business.

Reported other income in the second quarter of 2026 decreased $4 million. Reported net interest expense increased $10 million reflecting the impact of lower cash balances and new debt used to fund recent acquisitions.

The reported income tax rate for the second quarter of 2026 was 22.3% compared with the reported rate of 19.9% in the second quarter of 2025. Excluding special gains and charges and discrete tax items, the adjusted tax rate for the second quarter of 2026 was 21.0% compared with the adjusted tax rate of 20.8% in the second quarter of 2025.

Reported net income increased 2% versus the prior year. Excluding the impact of special gains and charges and discrete tax items, adjusted net income increased 9% versus the prior year.

Reported diluted earnings per share increased 3% versus the prior year. Adjusted diluted earnings per share increased 11% when compared against the second quarter of 2025.

As expected, currency translation had a $0.04 per share favorable impact on adjusted diluted earnings.

Ecolab repurchased approximately 1.2 million shares of its common stock during the second quarter of 2026.

Second Quarter 2026 Segment Review

Fixed currency sales grew 10%, driven by a 6% benefit from the Ovivo Electronics acquisition and accelerating organic sales growth of 4%. Global Water's accelerating performance was led by 29% organic growth in Global High-Tech, reflecting robust growth across both microelectronics and data centers. Growth in Food & Beverage continued to accelerate, driven by attractive new business wins from our One Ecolab growth strategy. Light Water also delivered improved growth, driven by solid gains across manufacturing, food & beverage, and institutional markets. Collectively, the headwind from softer sales in Heavy Water and Paper continued to ease, driven by good new business wins. As expected in this transition quarter, organic operating income increased 1% as accelerating pricing progressively offset growth-oriented investments in the business and higher commodity costs. Organic operating income growth is expected to improve in the third quarter, benefiting from strong pricing and continued new business wins.

Fixed currency and organic sales both grew 4%. Institutional’s performance improved, driven by good growth with hospitality customers. Specialty’s sales grew mid-single digits, reflecting share gains across quick service and food retail. Institutional & Specialty continues to significantly outperform soft market trends, reflecting good demand for Ecolab’s innovative products, digital solutions and service expertise that help customers improve performance, optimize labor, and reduce total costs. As expected in this transition quarter, organic operating income increased 6%, as accelerating pricing progressively overcame higher supply chain costs, including commodity cost inflation, and growth-oriented investments in the business. Organic operating income growth is expected to improve in the third quarter, benefiting from strong pricing and continued new business wins.

Fixed currency sales increased 9%, reflecting 7% organic growth and a 2% benefit from attractive, targeted acquisitions in North America. Strong organic sales growth was led by robust gains in restaurants, food retail, and food & beverage, which continue to benefit from our One Ecolab growth strategy. Organic operating income increased 12% as strong sales growth and improved productivity more than offset growth-oriented investments in the business, including pest intelligence.

Fixed currency and organic sales growth both accelerated to 15%. This strong performance was driven by continued robust share gains in bioprocessing and pharmaceutical & personal care, and improved performance in purification. Organic operating income increased 46%, as accelerated sales growth and a spike in bioprocessing offset growth-oriented investments in the business and higher commodity costs. Life Sciences’ organic operating income margin in the third quarter is expected to remain on its high-teens mid-term trajectory, reflecting very strong underlying performance and continued investments in breakthrough innovation, global capabilities, and capacity to fuel this high-growth, high-margin business.

Second quarter of 2026 corporate segment includes:

• amortization expense of $28 million related to the Nalco merger intangible assets, $21 million related to Purolite acquisition intangible assets and $10 million related to the Ovivo Electronics acquisition intangible assets
• special gains and charges were a net charge of $51 million, primarily related to One Ecolab and acquisition and integration costs

Special gains and charges for the second quarter of 2025 impacting operating expense were a net charge of $27 million primarily related to One Ecolab.

Business Outlook

2026

Long-term growth trends in water, hygiene, infection prevention, and digital technologies continue to fuel resilient demand for Ecolab’s innovative technologies and services. Strong momentum in Ecolab’s growth engines, which include Global High-Tech, Life Sciences, Pest Elimination and Ecolab Digital, is expected to continue to strengthen Ecolab’s overall performance. Ecolab’s investments in these areas position the company well to capitalize on these attractive long-term high-growth, high-margin opportunities.

In the near-term, the global operating environment remains complex, including constantly evolving geopolitics and international trade policy, which are resulting in rising commodity costs and customer disruptions in the Middle East. Importantly, the company is very well positioned to quickly mitigate the impact of these challenges. Over the past few years, Ecolab’s team has demonstrated it can adjust quickly to deliver high performance in almost any environment, which is why even with these dynamic macroeconomic conditions, Ecolab’s confidence in its performance trajectory remains strong. Pricing is expected to accelerate in the second half of the year, reflecting the full benefit from the energy surcharge implementation. At the same time, Ecolab remains focused on delivering incremental total value to customers that over time will exceed the total price increases.

With accelerating pricing and the acquisitions of Ovivo Electronics and CoolIT Systems, Ecolab expects reported sales in the second half of 2026 to increase 12% to 14%. Organic sales growth is expected to accelerate to the 6% to 7% range in the second half of the year as pricing strengthens and volumes continue to grow. The company anticipates adjusted operating income margin in the second half of the year to be approximately 19% and an organic operating income margin of approximately 20%.

As a result, Ecolab is raising its expectations for full year 2026 adjusted diluted earnings per share to the $8.05 to $8.25 range, rising 7% to 10% versus last year, which is higher than prior expectations of $8.03 to $8.23. This range reflects strong underlying performance and a short-term impact from non-cash amortization and financing costs of the CoolIT acquisition.

The company currently anticipates quantifiable special charges in 2026 to be approximately $0.75 to $0.80 per share, principally related to restructuring charges and acquisition and integration costs. Other than the special gains and charges noted above, other such amounts are not currently quantifiable.

2026 – Third Quarter

Ecolab expects third quarter 2026 adjusted diluted earnings per share in the $2.13 to $2.23 range, rising 3% to 8% compared with adjusted diluted earnings per share of $2.07 a year ago. This range reflects strong underlying performance and a short-term impact from non-cash amortization and financing costs of the CoolIT acquisition.

The company currently expects quantifiable special charges in the third quarter of 2026 to be approximately $0.28 per share, principally related to acquisition and integration costs and restructuring charges. Other than the special gains and charges noted above, other such amounts are not currently quantifiable.

Non-GAAP Financial Information

This news release and certain of the accompanying tables include financial measures that have not been calculated in accordance with accounting principles generally accepted in the U.S. (“GAAP”).

These non-GAAP financial measures may include:

• fixed currency sales
• organic sales
• adjusted gross profit
• adjusted gross margin
• adjusted fixed currency gross profit
• adjusted fixed currency gross margin
• organic gross profit
• organic gross margin
• fixed currency operating income
• fixed currency operating income margin
• adjusted operating income
• adjusted fixed currency operating income
• adjusted fixed currency operating income margin
• organic operating income
• organic operating income margin
• adjusted tax rate
• adjusted net income attributable to Ecolab
• adjusted diluted earnings per share

We provide these measures as additional information regarding our operating results. We use these non-GAAP measures internally to evaluate our performance and in making financial and operational decisions, including with respect to incentive compensation. We believe that our presentation of these measures provides investors with greater transparency with respect to our results of operations and that these measures are useful for period-to-period comparison of results.

Our non-GAAP financial measures for adjusted gross margin, adjusted gross profit and adjusted operating income exclude the impact of special (gains) and charges and our non-GAAP financial measures for adjusted tax rate, adjusted net income attributable to Ecolab and adjusted diluted earnings per share further exclude the impact of discrete tax items. Adjusted diluted earnings per share also excludes the impact of the Ovivo Electronics acquisition in the fourth quarter of 2025. We include items within special (gains) and charges and discrete tax items that we believe can significantly affect the period-over-period assessment of operating results and not necessarily reflect costs and/or income associated with historical trends and future results. After tax special (gains) and charges are derived by applying the applicable local jurisdictional tax rate to the corresponding pre-tax special (gains) and charges.

We evaluate the performance of our international operations based on fixed currency rates of foreign exchange, which eliminate the translation impact of exchange rate fluctuations on our international results. Fixed currency amounts included in this release are based on translation into U.S. dollars at the fixed foreign currency exchange rates established by management at the beginning of 2026. We also provide our segment results based on public currency rates for informational purposes.

Our reportable segments do not include the impact of intangible asset amortization from the Nalco, Purolite and Ovivo Electronics transactions or the impact of special (gains) and charges as these are not allocated to the Company’s reportable segments.

Our non-GAAP financial measures for organic sales, organic gross profit, organic gross margin, organic operating income and organic operating income margin are at fixed currency and exclude the impact of special (gains) and charges where applicable, the results of our acquired businesses from the first twelve months post acquisition and the results of divested businesses from the twelve months prior to divestiture.

These non-GAAP financial measures are not in accordance with, or an alternative to, GAAP and may be different from non-GAAP measures used by other companies. Investors should not rely on any single financial measure when evaluating our business. We recommend that investors view these measures in conjunction with the GAAP measures included in this news release. Reconciliations of our non-GAAP measures are included in the following "Supplemental Non-GAAP Reconciliations" and “Supplemental Diluted Earnings per Share Information” tables included in this news release.

We do not provide reconciliations for non-GAAP estimates on a forward-looking basis (including those contained in this news release) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of various items that have not yet occurred, are out of our control and/or cannot be reasonably predicted, and that would impact reported earnings per share and the reported tax rate, the most directly comparable forward-looking GAAP financial measures to adjusted earnings per share and the adjusted tax rate. For the same reasons, we are unable to address the probable significance of the unavailable information.
