ST. PAUL, Minn. – Aug. 9, 2021 – Ecolab Inc. (“Ecolab”) (NYSE: ECL) today announced that it has commenced offers (the “Exchange Offers”) to certain eligible holders to exchange its outstanding notes of the four series described in the table below (collectively, the “Old Notes”) for up to $500 million aggregate principal amount (the “Exchange Cap”) of its newly issued 2.750% Notes due 2055 (the “New Notes”) and cash. The New Notes will be a further issuance of, and will be in addition to, the 2.750% notes due 2055 (the “Original 2055 Notes”) that Ecolab expects to issue for cash on August 18, 2021, in the aggregate principal amount of $300 million.

The Exchange Offers will proceed on the terms and subject to the conditions set forth in a confidential offering memorandum dated August 9, 2021 (the “Confidential Offering Memorandum”) and related letter of transmittal (together, the “Exchange Offer Documents”).

The following table summarizes terms material to the determination of the consideration to be received in the Exchange Offers:

(1) Ecolab will accept Old Notes in the order of their respective Acceptance Priority Level specified in the table above (each, an “Acceptance Priority Level,” with 1 being the highest Acceptance Priority Level and 4 being the lowest Acceptance Priority Level), subject to the Exchange Cap and the other terms and conditions described in the Exchange Offer Documents.

(2) The Reference U.S. Treasury Security used to determine the Total Exchange Consideration (as defined in the Confidential Offering Memorandum and determined in accordance with the formula set forth in Annex A of the Confidential Offering Memorandum) for the applicable series of Old Notes, as displayed on the Bloomberg Government Pricing Monitor Page FIT1.

(3) To be paid in New Notes and cash per $1,000 principal amount of Old Notes as described in the Exchange Offer Documents, which Cash Amount (as defined below) is subject to adjustment upon the terms and conditions contained in the Exchange Offer Documents, including the Adjusted Cash Amount (as defined in the Confidential Offering Memorandum), which is reduced by $50.00 (the “Early Participation Amount”) to the extent that Eligible Holders validly tender Old Notes of any series after the Early Participation Date (as defined below) and before the Expiration Date (as defined below). Hypothetical Total Exchange Consideration was calculated using a reference yield as of 2:00 p.m., New York City time, on August 9, 2021, assuming an Early Participation Settlement Date (as defined below) of August 24, 2021. Actual amounts will be determined at the Pricing Time (as defined below). Does not reflect any accrued and unpaid interest. Ecolab will pay accrued and unpaid interest on the Old Notes up to, but not including, the applicable Settlement Date, which will be reduced by the interest accrued from August 18, 2021, the initial issuance date of the Original 2055 Notes up to, but not including the applicable Settlement Date, as further described in the Exchange Offer Documents. The first interest payment for the New Notes will include accrued interest from August 18, 2021.

(4) Cash Amounts are shown for illustrative purposes only. Prices will be determined at the Pricing Time. The Cash Amounts do not include accrued and unpaid interest on the Old Notes accepted for exchange, which will be payable in addition to the applicable Total Exchange Consideration.

The Exchange Offers will expire at 11:59 p.m. (New York City time) on September 3, 2021 (as the same may be extended, the “Expiration Date”). Subject to the Acceptance Priority Levels and proration procedures described in the Exchange Offer Documents, holders who validly tender and do not validly withdraw Old Notes at or prior to 5:00 p.m., New York City time, on August 20, 2021, unless extended for an Exchange Offer (the “Early Participation Date”), and whose tenders are accepted for exchange by Ecolab, will receive for each $1,000 principal amount of Old Notes the applicable Total Exchange Consideration (without deduction of the Early Participation Amount from the Adjusted Cash Amount) on the applicable Early Participation Settlement Date (as defined in the Confidential Offering Memorandum), which is expected to be August 24, 2021. Subject to the Acceptance Priority Levels and proration procedures described in the Exchange Offer Documents, holders who validly tender and do not validly withdraw Old Notes after the applicable Early Participation Date but at or prior to the Expiration Date, and whose Old Notes are accepted for exchange by Ecolab, will receive for each $1,000 principal amount of Old Notes the applicable Total Exchange Consideration (with a deduction of the Early Participation Amount from the Adjusted Cash Amount). Old Notes tendered for exchange at or prior to the applicable Early Participation Date will have priority over Old Notes tendered for exchange after the applicable Early Participation Date. The Old Notes accepted for exchange on any Settlement Date will be accepted in the order of priority set forth in the table above with 1 being the higher acceptance priority level.

The Total Exchange Consideration for Old Notes validly tendered and accepted for exchange by Ecolab, will consist of (i) a principal amount of New Notes applicable to such tendered Old Notes and (ii) a cash payment (as it may be adjusted as provided in the Confidential Offering Memorandum, the “Cash Amount”) in the respective amount referenced below:

Ecolab may, at its option, elect to increase or decrease the principal amount of New Notes exchangeable for each $1,000 principal amount of the applicable Old Notes tendered and accepted pursuant to the applicable Exchange Offer by up to $100 per $1,000 principal amount. Any such election will be announced as soon as reasonably practicable after the Pricing Time.

As further described in the Exchange Offer Documents, the applicable Total Exchange Consideration will be determined at 10:00 a.m., New York City time, on August 23, 2021 (the “Pricing Time”) based upon the discounted value of the remaining payments of principal and interest on the Old Notes through the par call date, in the case of the Old 2047 Notes, the Old 2046 Notes and the Old 2030 Notes, and to the maturity date, in the case of the Old 2041 Notes, using a yield equal to the sum of bid-side yield on the reference U.S. treasury security identified in the first table above plus the fixed spread set forth in such table.

The “Early Participation Settlement Date” will be promptly following the Early Participation Date and is expected to be on August 24, 2021, which is the second business day after the Early Participation Date. The “Final Settlement Date” will be promptly following the Expiration Date and is expected to be September 8, 2021, which is the second business day after the Expiration Date. The Early Participation Settlement Date and the Final Settlement Date are each referred to herein as the “Settlement Dates.”

Although participants in the Exchange Offers will not hold New Notes prior to the applicable Settlement Date, the first interest payment on the New Notes will include the interest accrued from August 18, 2021, the expected issuance date of the Original 2055 Notes, to the applicable Settlement Date. Further, each holder whose Old Notes are accepted for exchange by Ecolab will receive a cash payment (reduced as described in the following sentence) representing interest, if any, that has accrued from the most recent interest payment date in respect of the Old Notes up to, but not including, the applicable Settlement Date; provided, that holders of Old Notes will not receive accrued and unpaid interest that is due and payable on the applicable Settlement Date if the accrued and unpaid interest that is due and payable on the applicable settlement date on the New Notes exceeds the accrued and unpaid interest that is due and payable on the applicable settlement date on such Old Notes. Interest payable on Old Notes up to, but not including, the applicable Settlement Date will be reduced by the interest accrued on the New Notes up to, but not including, the applicable Settlement Date.

Old Notes tendered may be validly withdrawn at any time at or prior to 5:00 p.m. (New York City time) on August 20, 2021 (the “Withdrawal Deadline”), provided that Ecolab may extend the Early Participation Date with respect to any Exchange Offer without extending the Withdrawal Deadline, unless required by law. Old Notes tendered after the Withdrawal Deadline may not be withdrawn, except where additional withdrawal rights are required by law (as determined by Ecolab in its sole discretion).

Only holders who have duly completed and submitted an eligibility letter (which may be found at www.dfking.com/ecolab) will be authorized to receive the Exchange Offer Documents and participate in the Exchange Offers. The eligibility letters will include certifications that the holder is either (1) a “qualified institutional buyer” as defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), or (2) a non-“U.S. person” (as defined in Rule 902 under the Securities Act) located outside of the United States who is (i) not acting for the account or benefit of a U.S. person, (ii) a “non-U.S. qualified offeree” (as defined in the Exchange Offer Documents), and (iii) not resident in Canada.

If and when issued, the New Notes will not be registered under the Securities Act or any state securities laws. Therefore, the New Notes may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and any applicable state securities laws.
