PRESS RELEASE

2026 EPS Guidance and Long-Term Financial Targets Affirmed

The company affirms its 2026 adjusted earnings per share (“EPS”) guidance range of $6.02 to $6.12 (non-GAAP). The 2026 adjusted EPS guidance range does not include (i) transaction costs to be incurred by the company during 2026 related to the proposed merger with Essential Utilities, Inc. (“Essential Utilities”), (ii) impacts of weather during 2026, and (iii) incremental interest income through February 13, 2026 related to the 2024 amendment of the former Homeowner Services Group (“HOS”) secured seller note. Management is unable to present a reconciliation of the adjusted EPS guidance range to a GAAP guidance range without unreasonable effort because management cannot reliably predict the nature, amount or probable significance of all of such adjustments for future periods; however, these adjustments may, individually or in the aggregate, cause adjusted EPS to differ significantly from GAAP EPS. The company also affirms its long-term financial targets, including its long-term EPS and dividend growth rate targets of 7-9%. The company’s earnings forecasts are subject to numerous risks and uncertainties, including, without limitation, those described under “Adjustments to GAAP” and “Cautionary Statement Concerning Forward-Looking Statements” below and under “Risk Factors” in its annual, quarterly, and current reports filed with the Securities and Exchange Commission (“SEC”).
