Advanced Drainage Systems Announces Pricing of $500 Million of 5.375% Senior Notes Due 2034

Advanced Drainage Systems, Inc. (NYSE: WMS) (“ADS” or the “Company”), a leading provider of innovative water management solutions in the stormwater and onsite wastewater industries, today announced that it priced a private offering (the “Offering”) of $500 million aggregate principal amount 5.375% senior unsecured notes due 2034 (the “Notes”). The Company’s present and future direct and indirect domestic subsidiaries that guarantee its senior secured credit facility will guarantee the Notes. The Offering is expected to close on February 27, 2026, subject to customary closing conditions.

In connection with the issuance of the Notes, the Company expects to amend its existing senior secured credit facility to (i) increase the revolving credit facility from $600 million to $750 million, (ii) increase the term loan “B” from $408 million to $600 million, and (iii) extend the maturity date (the “Amended Credit Facility”). The closing of this Offering is not conditioned on the closing of the Amended Credit Facility. The completion of the Amended Credit Facility is also subject to customary closing conditions and there can be no assurance as to whether or when the Amended Credit Facility may be completed, if at all.

The Company intends to use the net proceeds from the Offering, together with the proceeds of the term loan “B” portion of the Amended Credit Facility, to refinance the outstanding balance under the existing senior secured credit facility and redeem all of the Company’s outstanding 5.000% senior notes due 2027 with the balance for general corporate purposes.

The Notes and the related guarantees have not been, and will not be, registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any other jurisdiction. The Notes and the related guarantees may not be offered or sold within the United States or to United States persons, except to persons reasonably believed to be qualified institutional buyers in reliance on an exemption from registration provided by Rule 144A under the Securities Act and to certain non-U.S. persons outside the United States in reliance on Regulation S under the Securities Act.

This press release is neither an offer to sell nor a solicitation of an offer to buy the Notes, the related guarantees or any other securities of ADS, nor shall there be any sale of the Notes, the related guarantees or any other securities of ADS in any jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. The foregoing does not constitute a notice of redemption with respect to ADS’ 5.000% senior notes due 2027.
