Ecolab Comments on the Effects of Hurricane Harvey

Commenting on the effects of Hurricane Harvey, Douglas M. Baker, Jr., Ecolab’s Chairman and Chief Executive Officer said, “The damage caused by Hurricane Harvey to the people in its path has been immense and tragic. We are pleased that our Ecolab associates are safe and we are supporting them in the recovery. Our hearts and best wishes go out to everyone affected by the storms as they seek to rebuild. To assist, we have donated 10 truckloads of cleaning and sanitizing products and are matching our global associates’ financial contributions for those in need in the affected area.

“The effects of the hurricane on our customers, our plants and operations and our raw material costs are still playing out and it is too early to formally quantify them. However, a number of our industrial and refining customers were forced to shut down their operations, as we were for our three manufacturing plants in the Houston area. As a result, we currently believe the impact could result in third quarter adjusted diluted earnings per share on the low end or slightly below our previously forecasted $1.36 to $1.44 range, and likely on the lower end of our full year 2017 range of $4.70 to $4.90. We expect to update our full year 2017 guidance on or before the third quarter earnings release.

“Importantly, we believe Hurricane Harvey’s impact will be temporary, and that the fundamental strengthening trends within our business sales and margins are continuing and will be reflected in our results going forward. We do not believe there will be any meaningful impact on our 2018 results. Obviously, this does not include prospective impacts from other hurricanes.”

Non-GAAP Financial Information

This news release includes estimates for adjusted earnings per share, which is a financial measure that has not been calculated in accordance with accounting principles generally accepted in the U.S. (“GAAP”).

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

Our non-GAAP financial measure for diluted earnings per share, which we refer to as adjusted diluted earnings per share, excludes the impact of special (gains) and charges and discrete tax items. 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 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.

Adjusted earnings per share is a financial measure that is 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 non-GAAP financial measures in conjunction with the GAAP measures.
