The Company has also become aware of a number of substantially similar personal injury short-form complaints that had been filed in the MDL naming, in addition to various other water providers and manufacturers, certain Company utility subsidiaries as defendants. The Company believes that the claims asserted are without merit and the relevant utility subsidiaries have valid, meritorious defenses to the claims. In October 2025, all MDL personal injury complaints that the Company had been made aware of were dismissed by the plaintiffs without prejudice.

Environmental, Health and Safety, and Water Quality Regulation

On April 10, 2024, the U.S. Environmental Protection Agency (“EPA”) announced a final National Primary Drinking Water Regulation (“NPDWR”) for six PFAS including PFOA, PFOS, PFNA, HFPO-DA, PFHxS, and PFBS. The NPDWR for PFAS establishes legally enforceable levels, called maximum contaminant levels, for PFAS in drinking water. Utilities will be required to complete their initial monitoring for PFAS by 2027, followed by ongoing compliance monitoring. Although the EPA has indicated their intent to extend the compliance deadline to 2031, under the current rule utilities will be required to comply with the new MCLs by April 2029, implementing solutions to reduce PFAS levels where needed. Beginning in April 2029, utilities that exceed any of the PFAS MCLs will be required to provide notification to the public of the violation.

Upon initial review of the compliance requirements in 2024, the Company estimated an investment of approximately $1 billion of capital expenditures to install additional treatment facilities in order to comply with the new regulations by April 2029. The Company currently estimates an investment of approximately $2 billion of capital expenditures to install additional treatment facilities in order to comply with the NPDWR as proposed.
