ST. PAUL, Minn., October 25, 2011:  Ecolab delivered strong third quarter results as adjusted earnings per share increased 14% over last year. These results were driven by continued strong sales growth, led by its Food & Beverage business in nearly every region, along with robust Latin America, Asia Pacific and Canadian sales. This growth, coupled with over-performance in both our newly acquired businesses and in our efficiency programs, enabled Ecolab to overcome much higher than expected delivered product costs.

Ecolab’s reported sales rose 11% to a record $1.7 billion in the third quarter of 2011; when measured in fixed currencies, sales rose 6%.  Adjusted for currency and acquisitions, sales rose 3%.  Reported net income attributable to shareholders declined 11% to $154 million, representing $0.65 per share.

Third quarter 2011 and 2010 results included special gains and charges and discrete tax items.  Excluding those items, adjusted third quarter 2011 net income attributable to shareholders rose 13% to $177 million.  Adjusted diluted earnings per share increased 14% to $0.75, reaching the top end of Ecolab’s forecasted range.  Third quarter 2010 adjusted diluted earnings per share were $0.66.  Currency translation had a favorable effect on reported and adjusted diluted earnings per share of $0.03 per share in the third quarter of 2011.

Segment review

Third quarter 2011 sales for Ecolab’s U.S. Cleaning & Sanitizing operations rose 6% to $763 million.  Adjusted for acquisitions, sales increased 3%.   Food & Beverage and Healthcare led the growth, while good underlying Institutional and Kay growth in the quarter was somewhat offset by prior year new product and program pipeline filling and large new customer rollouts.  Ecolab’s U.S. Cleaning & Sanitizing operating income increased 6% to $158 million.  Adjusted for acquisitions, U.S. Cleaning & Sanitizing operating income was flat, reflecting significantly higher delivered product costs.

U.S. Other Services sales increased 2% to $120 million in the third quarter.  Operating income increased 6% to $21 million as GCS became profitable.

Sales for Ecolab’s International operations, when measured at fixed currency rates, grew 6% to $797 million in the third quarter.  Adjusted for acquisitions and divestitures, fixed currency sales increased 4%.  Fixed currency operating income increased 9% to $88 million in the third quarter.  Adjusted for acquisitions and

2

divestitures, International fixed currency operating income increased 8% as strong regional growth and significant benefits from our European efficiency programs offset significantly higher delivered product costs.  When measured at public currency rates, International sales increased 18% and operating income rose 23%.

The Corporate segment includes special gains and charges.  Special gains and charges for the third quarter 2011 of $28 million ($24 million after-tax) primarily consisted of charges from the previously announced European restructuring as well as the anticipated Nalco merger and integration costs.  Special gains and charges for the third quarter 2010 were a net gain of $5 million (before and after tax).  The Corporate segment also includes investments in the development of business systems and other corporate investments we are making as part of our ongoing efforts to improve our efficiency and returns.

The reported income tax rate for the third quarter 2011 was 31.8% and compared with the reported rate of 24.3% in the third quarter 2010.  The substantially lower third quarter 2010 reported tax rate was due primarily to the favorable settlement of an IRS appeals case in that period.  Excluding the tax rate impact of special gains and charges and discrete tax items, the adjusted effective income tax rate in the third quarter 2011 was 30.2% compared with 30.3% for the same period last year.

CEO comment

Commenting on the quarter, Douglas M. Baker, Jr., Ecolab’s Chairman, President and Chief Executive Officer said, “We delivered very good results in a challenging environment. Most importantly, we have set ourselves up to deliver a strong 2011 and are continuing to build momentum leading into 2012.

“Our sales growth remained on-track and outperformed our markets. We had excellent new business results and our strong portfolio of new products continues to gain traction. Additionally, all of our recent acquisitions continue to outperform our expectations. These results, combined with our success in realizing leverage from our cost efficiency programs and our European restructure program in particular, allowed us to overcome significantly higher than anticipated raw material costs.

“We are pleased with our position. We anticipate strong sales growth momentum in the fourth quarter, with raw material comparisons expected to ease and pricing on-track to more than offset those costs going forward. When we combine this with the

3

continued strong efforts to build our businesses and the European restructure work we have underway, we see continued strong results in front of us.

“This perspective only gets brighter when we factor in the benefits of our Nalco merger. We still anticipate a successful close in the fourth quarter.  We are well into the integration planning work with Nalco to prepare for the transaction’s close and the subsequent integration of our businesses.  We have strong integration teams working to pull the businesses together quickly and successfully upon the transaction close, and we are preparing to deliver great performance in 2012.The more we have learned about the Nalco business, the more it has increased our confidence in the opportunities we have together and the benefits it will bring for our customers, shareholders and associates.”

Business Outlook

2011

Ecolab narrowed its 2011 full-year forecast.  Ecolab now expects adjusted earnings per share, excluding the anticipated impact of the Nalco merger, to be in the $2.53 to $2.55 range, up 13% to 14% compared to 2010 adjusted earnings per share.  Ecolab previously forecast 2011 earnings per share to be in the $2.52 to $2.56 range.

Special gains and charges for 2011 are expected to approximate a $0.45 per share net charge, primarily driven by Europe restructuring charges and Nalco merger and integration costs.  Future amounts related to discrete tax items for 2011, if any, are not currently quantifiable.

2011 — Fourth Quarter

Ecolab expects improved year-over-year sales growth in the fourth quarter 2011.  Gross margins are expected to increase, reflecting the impact of pricing and efficiency initiatives as well as the lessening impact of delivered product cost increases.  The SG&A ratio should reflect year-on-year improvement from sales leverage which is expected to more than offset continued investment in the business.

Our outlook for the fourth quarter 2011, which excludes the impact of the anticipated Nalco merger, is as follows:

4

We expect fourth quarter 2011 special gains and charges, including restructuring charges, to be a net charge of approximately $0.20 per share, nearly all of which will be merger and integration charges related to the Nalco transaction.

Reported fourth quarter 2010 earnings per share of $0.56 included special gains and charges and discrete tax items.  Excluding these items, fourth quarter 2010 adjusted diluted earnings per share were $0.60.

Nalco merger update

Ecolab continues to expect to close on the Nalco merger in the fourth quarter 2011.  Ecolab established a record date of October 11, 2011 for the special meeting of stockholders to approve the issuance of Ecolab common stock in the merger.  In addition, Ecolab now has credit facilities in place to fund the cash portion of the merger consideration and retire Nalco bank debt.

Ecolab and Nalco have submitted notifications with competition authorities in the U.S., European Union, Australia, Canada, China, Colombia, Mexico, Russia, South Korea and Turkey.  We have received clearances without imposed conditions from the U.S., Australia, Canada, Mexico, Russia, South Korea and Turkey.  We continue to expect to obtain all required regulatory clearances to enable us to close the transaction in the fourth quarter.

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 include fixed currency sales, fixed currency operating income, adjusted operating income, adjusted effective tax rate, adjusted net income attributable to shareholders and 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.

We include in special gains and charges items that are unusual in nature, significant in amount and important to an understanding of underlying business performance. In order to better allow investors to compare underlying business performance period-to-period, we provide adjusted operating income, adjusted net income attributable to shareholders and adjusted diluted earnings per share, which excludes special gains and charges and discrete tax items.

The adjusted effective tax rate measure promotes period-to-period comparability of the underlying effective tax rate because the amount excludes the tax rate impact of

9

special gains and charges and discrete tax items which do not necessarily reflect costs associated with historical trends or expected future costs.

We evaluate the performance of our international operations based on fixed currency rates of foreign exchange. Fixed currency sales and fixed currency operating income measures eliminate the impact of exchange rate fluctuations on our international sales and operating income, respectively, and promote a better understanding of our sales and operating income trends from underlying business performance. 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 2011.

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. A reconciliation of reported diluted earnings per share to adjusted diluted earnings per share is provided in the table “Supplemental Diluted Earnings per Share Information” included in this news release.
