Item 1.01. Entry Into a Material Definitive Agreement.

On February 18, 2020, EWT Holdings III Corp. (“EWT III”), an indirect wholly-owned subsidiary of Evoqua Water Technologies Corp. (the “Company”), entered into Amendment No. 7 (the “Amendment”), among EWT III, as the borrower, EWT Holdings II Corp., as parent guarantor, the subsidiary guarantors party thereto, the financial institutions party thereto, and Credit Suisse AG, as administrative agent and collateral agent, relating to the First Lien Credit Agreement, dated January 15, 2014 (as amended, amended and restated, extended, supplemented or otherwise modified from time to time prior to the effectiveness of the Amendment, the “Existing Credit Agreement”; the Existing Credit Agreement, as amended by the Amendment, the “Credit Agreement”), among EWT III, as the borrower, EWT Holdings II Corp., as parent guarantor, the financial institutions from time to time party thereto, as lenders, and Credit Suisse AG, as administrative agent and collateral agent.

Prior to the Amendment, term loans in an aggregate principal amount of approximately $826 million (the “Existing Term Loans”) were outstanding under the Existing Credit Agreement. Pursuant to the Amendment, the Existing Term Loans were refinanced with the proceeds of refinancing term loans (the “Refinancing Term Loans”).

The Amendment amended the Existing Credit Agreement to, among other things, (i) reduce the interest rate spread applicable to term loans based on LIBOR from (A) 2.75% to 2.50% per annum during any period during which EWT III maintains a public corporate family rating better than or equal to B1 from Moody’s and B+ from S&P, in each case with a stable outlook (a “Ratings Condition Period”), and (B) 3.00% to 2.75% per annum for any period other than a Ratings Condition Period; (ii) reduce the interest rate spread applicable to term loans based on the Base Rate from (A) 1.75% to 1.50% per annum during any Ratings Condition Period and (B) 2.00% to 1.75% per annum during any period other than a Ratings Condition Period; (iii) remove the 1.00% floor for term loans based on LIBOR and the 2.00% floor for term loans based on the Base Rate; (iv) schedule existing indebtedness and investments, allowing EWT III and its subsidiaries to incur incremental indebtedness and make incremental investments under the applicable baskets; (v) increase the generally permitted investments basket; and (vi) extend the 1.00% prepayment premium for refinancings in connection with certain repricing transactions through August 18, 2020.

The other terms of the Credit Agreement are generally the same as the terms of the Existing Credit Agreement. The Amendment was subject to various conditions and contains various representations and warranties, including no default or event of default under the Loan Documents (as defined in the Credit Agreement) and bring-downs of the representations and warranties made by the Loan Parties (as defined in the Credit Agreement) in the Loan Documents.

The foregoing description of the Amendment does not propose to be complete and is qualified in its entirety by reference to the full text of the Amendment, a copy of which is attached hereto as Exhibit 10.1, and the terms of which are incorporated herein by reference.
