Exhibit 99.1 Essential Utilities Reports Strong First Quarter 2025 Results, 2025 Guidance and Long-Term Targets Affirmed · Earnings per share of $1.03 for Q1 2025 vs. $0.97 for Q1 2024 · 2025 earnings per share guidance range of $2.07 to $2.11 affirmed · Long-term targets also affirmed · Invested $270.5 million in the first three months of the year; on track to invest $1.4 to $1.5 Billion in infrastructure in 2025 · Closed on acquisition of utility assets from the Village of Midvale, OH BRYN MAWR, Pa. (May 12, 2025) – Essential Utilities Inc. (NYSE: WTRG) today reported results for the first quarter ended March 31, 2025. Essential’s net income of $283.8 million or $1.03 per share for the first quarter of 2025 compared favorably to $265.8 million or $0.97 per share reported for the first quarter of 2024. “We’re off to a great start to the year,” said Essential Utilities Chairman and Chief Executive Officer Christopher Franklin. “Our investments in infrastructure have set the stage for achieving our expected growth in 2025 and beyond. We are excited to also announce that, for the third consecutive year, we have been named to USA Today’s annual list of Climate Leaders. We are proud that our commitment to protecting and providing essential resources for life continues to be recognized”. First Quarter 2025 Operating Results Essential reported net income of $283.8 million and earnings per share of $1.03 for the first quarter of 2025, compared to net income of $265.8 million and earnings per share of $0.97 for the same period in 2024. Comparing this quarter’s earnings to those of first quarter of 2024, increased revenues from regulatory recoveries, higher regulated natural gas segment volumes, and lower expenses, and a higher tax benefit were partially offset by a prior year gain on the sale of the combined-heat-and-power business valued at 24 cents per share. Revenues for the quarter were $783.6 million compared to $612.1 million in the first quarter of 2024, an increase of 28%. Additional revenues from regulatory recoveries, purchased gas costs, and higher regulated natural gas segment volumes were the primary revenue drivers. Operations and maintenance expenses increased to $137.8 million for the first quarter 2025, compared to $136.9 million in the first quarter of 2024, primarily due to an increase in customer assistance surcharge costs in our regulated natural gas segment, which has an equivalent offsetting amount in revenues, and increases in employee-related costs and production expenses, offset by decreases in bad debt expense, outside services, and other costs. Essential’s regulated water segment reported revenues for the quarter of $300.8 million, an increase of 7.5% compared to $279.9 million in the first quarter of 2024. Rates and surcharges were the largest contributor to the increase in revenues for the period. Operations and maintenance expenses for Essential’s regulated water segment decreased to $89.4 million for the first quarter of 2025 compared to $90.7 million in the first quarter of 2024, driven partially by a decrease in bad debt expense, offset by increased production costs for water and wastewater operations, and increased employee related costs. Essential’s regulated natural gas segment reported revenues for the quarter of $470.8 million, compared to $324.3 million in the first quarter of 2024, driven primarily by an increase in purchased gas costs and the impact of higher volumes delivered due to colder weather conditions during the first quarter of 2025 as compared to 2024. Operations and maintenance expenses for Essential’s regulated natural gas segment increased to $55.7 million for the first quarter of 2025 compared to $45.9 million in the first quarter of 2024 primarily due to an increase in customer assistance surcharge costs which has an equivalent offsetting amount in revenues; and increases in labor and employee benefits and increase in legal expenses, offset by a decrease in materials and supplies Dividend As previously announced on February 19, 2025, Essential’s board of directors declared a quarterly cash dividend of $0.3255 per share of common stock. This dividend will be payable on June 2, 2025, to shareholders of record on May 13, 2025. The company has paid a consecutive quarterly cash dividend for more than 80 years. Financing As of March 31, 2025, Essential’s weighted average cost of fixed-rate long-term debt was 4.02%, and the company had $728 million available on its credit lines. On August 13, 2024, Essential established an at-the-market equity sales program (“ATM”), under which it may issue and sell shares of common stock up to an aggregate offering price of $1.0 billion. During the three months ended March 31, 2025, we issued 1,627,009 shares of common stock for net proceeds of approximately $63 million. In April 2025, we issued 3,664,762 common shares for net proceeds of approximately $145 million. On March 19, 2025, the Company established a commercial paper program that allows it to issue, through private placement, short-term unsecured commercial paper notes in an aggregate principal amount not to exceed $1.0 billion. This program, which is backstopped by the Company’s revolving credit facility, will allow the company to reduce short-term borrowing costs associated with investing in needed infrastructure investments. Rate Activity As of May 9, 2025, the company’s regulated water segment received rate awards or infrastructure surcharges in Pennsylvania, North Carolina and Ohio, of $89.6 million, and its regulated natural gas segment received rate awards or infrastructure surcharges in Kentucky of $0.5 million. The company currently has a base rate case pending in Kentucky for its regulated natural gas segment for an estimated $10.9 million in incremental annual revenues. In addition, the company has a base rate case pending in North Carolina for its regulated water and wastewater segment for an estimated $45 million in incremental annual revenues. Capital Expenditures Essential invested approximately $271 million in the first three months of 2025 to improve its regulated water and natural gas infrastructure systems and to enhance customer service across its operations. The company continues to be a leader in the country at replacing miles of aged underground utility pipe and is committed to maintaining elevated levels of infrastructure investment. The company is on track to invest between $1.4 and $1.5 billion in needed infrastructure investments in 2025. From 2025 through 2029, the company plans to invest approximately $7.8 billion to improve water and natural gas systems and better serve customers through improved information technology. Essential’s investments during this five-year period include addressing PFAS with at least $450 million in capital projects, replacing and expanding its water and wastewater utility infrastructure, and replacing and upgrading its natural gas utility infrastructure, with the latter leading to significant reductions in methane emissions that occur in aged gas pipes. The company is a leader in remediating PFAS and will comply with the final EPA rule. The capital investments made to rehabilitate and expand the infrastructure of the communities’ Essential serves are critical to its mission of safely and reliably delivering Earth’s most essential resources. Water Utility Growth by Acquisition Essential’s continued growth by acquisition allows the company to provide safe and reliable water and wastewater service to a larger customer base than it could from organic customer growth alone. Since 2015, Essential collectively has acquired over $518 million in rate base and added more than 129,000 new customers or equivalent dwelling units to the company’s footprint. In April 2025, the Company acquired the Village of Midvale’s water system in Ohio, which serves approximately 1,000 customers for approximately $3 million. In January 2025, the Company acquired Greenville Sanitary Authority’s wastewater utility assets, which serve approximately 2,300 customers in Greenville, Pennsylvania for $18 million. The company has five signed purchase agreements for additional wastewater systems in Pennsylvania and Texas that are pending closing and are expected to serve over 210,000 customers or equivalent dwelling units and total approximately $340 million in purchase price. The company’s $276.5 million agreement to acquire the Delaware County Regional Water Quality Control Authority (DELCORA), a Pennsylvania sewer authority that serves approximately 198,000 equivalent dwelling units in the Philadelphia suburbs, is included among these signed purchase agreements. The pipeline of potential water and wastewater municipal acquisitions the company is actively pursuing represents approximately 400,000 total customers.
