Exhibit 99.1 Essential Utilities Reports Financial Results for Full Year 2025 · Earnings per share increases to $2.20 for Full Year 2025 · Record $1.4 billion invested in infrastructure during the year · Shareholder approval secured for announced merger with American Water BRYN MAWR, Pa. (February 25 th , 2026) – Essential Utilities Inc. (NYSE: WTRG) today reported results for the fourth quarter and full year ended December 31 st , 2025. Essential’s net income was $616.4 million or $2.20 per share for the full year of 2025, compared to net income of $595.3 million and $2.17 per share for the prior year. The full year 2024 net income and earnings per share included the benefit of a gain on sale related to the sale of the Pittsburgh area energy projects, as well as extreme weather and associated tax impacts. The company previously disclosed that, adjusting for these effects, the adjusted 2024 earnings per share was $1.97 on a non-GAAP basis. Essential’s net income was $132.7 million or $0.47 per share for the fourth quarter of 2025. “2025 was truly a banner year for the company,” said Essential Utilities Chairman and Chief Executive Officer Christopher Franklin. “I am proud of the work our team has done to achieve excellence in operations, from continuing to execute our $450 million PFAS capital plan, to exceeding our Intelis gas meter installation goal, truly delivering for our customers. Additionally, we continued our track record of achieving strong growth, which allowed us to once again increase the dividend and continue our infrastructure investment program.” “Now, with our shareholders having overwhelmingly approving the historic merger of Essential Utilities and American Water at our special meeting on February 10 th , we are well-positioned to deliver for our stakeholders for generations to come,” Franklin added. Full Year 2025 Operating Results Essential reported net income of $616.4 million and earnings per share of $2.20 for the full year of 2025, compared to net income of $595.3 million and earnings per share of $2.17 for the full year of 2024 on a GAAP basis. Compared with prior year earnings, primary drivers include increases in rates and higher gas volumes, partially offset by a gain on sale of gas assets in the prior year, higher operations and maintenance expense, and higher depreciation and amortization expense. The company previously disclosed that its adjusted 2024 earnings per share was $1.97 on a non-GAAP basis.

Capital Expenditures Essential invested over $1.4 billion in 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 in replacing miles of aged underground utility pipe and addressing PFAS. Essential is committed to maintaining elevated levels of infrastructure investment. 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. During 2025, Essential completed three acquisitions of water and wastewater systems, which along with the organic growth in existing systems, represent over 12,700 new customers. Since 2015, Essential collectively has acquired approximately $550 million in rate base and added more than 135,000 new customers or equivalent dwelling units to the company’s footprint. The company has four signed purchase agreements for additional wastewater systems in Pennsylvania and Texas that are pending closing and are expected to serve over 200,000 customers or equivalent dwelling units and total approximately $300 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. Merger with American Water Works Company, Inc. The company is continuing to progress through the process of obtaining the consents and approvals needed to successfully consummate the proposed merger with American Water. In 2025, Essential submitted applications for required regulatory approval in all states where applicable. On February 10th, 2026, shareholders of both companies voted overwhelmingly in favor of the merger-related proposals. The merger remains on track for closing in the first quarter of 2027. Financial and Growth Guidance The company’s latest expectations are the following: · Anticipated growth in long-term earnings per share at a compounded annual growth rate of 5 to 7% from the adjusted 2024 earnings per share of $1.97 (Non-GAAP) for the three-year period through 2027. · In 2026, regulated infrastructure investments are expected to be $1.7 billion. · Multiyear plan to ensure that finished water does not exceed the federal maximum contaminant level of the six EPA-regulated PFAS chemicals. Guidance Assumptions Essential Utilities does not guarantee future results of any kind. Guidance is subject to risks and uncertainties, including, without limitation, those factors outlined in the “Forward Looking Statements” of this release and the “Risk Factors” section of the company’s annual and quarterly reports filed with the Securities and Exchange Commission. The earnings per share and infrastructure investment include the municipal water and wastewater acquisitions for which the company has entered into signed purchase agreements as of the date the guidance was announced, but do not include DELCORA or other potential acquisitions from the company’s list of acquisition opportunities that currently represents over 400,000 customer equivalents. While the company remains confident in its ability to close DELCORA, for guidance purposes, DELCORA has been removed from all guidance metrics. The company’s guidance includes the expectation that the company will continue to issue equity and debt on an as-needed basis to support acquisitions and capital investment plans. Essential Utilities believes that the non-GAAP financial measure “adjusted earnings per share” used for 2024 and identified as part of its multi-year financial and growth guidance provides investors the ability to measure the company’s financial operating performance for 2024 by adjustment, which was more indicative of the company’s ongoing operating performance in 2024.

The Company believes that the non-GAAP financial measures “adjusted income” and “adjusted diluted income per common share” provide investors the ability to measure the Company’s financial operating performance by adjustment, which is more indicative of the Company’s ongoing operating performance. The Company further believes that the presentation of these non-GAAP financial measures is useful to investors as a more meaningful way to compare the Company’s operating performance against its guidance range for 2024. This reconciliation includes a presentation of the non-GAAP financial measures “adjusted income” and “adjusted diluted income per common share” and have been adjusted for the following items: (1) During the first quarter of 2024, the Company completed the sale of its interest in three non-utility local microgrid and distributed energy projects and recognized a gain of $91,236, net of transaction expenses. In October 2023, the Company completed the sale of its regulated natural gas utility assets in West Virginia. In 2024, the Company received additional proceeds from this sale of regulated natural gas utility assets in West Virginia and post-transaction activities. (2) Estimated impact to Peoples Natural Gas (PNG) operating revenues from warmer than normal weather conditions during 2024 and nonrecurring usage. These impacts are partially offset by favorable regulated water consumption in 2024 due to drier than normal weather conditions. (3) The income tax impact of the non-GAAP adjustments described above. These financial measures are measures of the Company’s operating performance that do not comply with U.S. generally accepted accounting principles (GAAP), and are thus considered to be “non-GAAP financial measures” under applicable Securities and Exchange Commission regulations. These non-GAAP financial measures are derived from our consolidated financial information, if available, and is provided to supplement the Company’s GAAP measures, and should not be considered as a substitute for measures of financial performance prepared in accordance with GAAP. The following reconciles our GAAP results to the non-GAAP information we disclose : Year Ended December 31, 2024 Net income (GAAP financial measure) $ 595,314 Adjustments: (1) Gain on sales of assets and related transaction activities (94,024 ) (2) Adjustments for estimated effects of unfavorable weather (addback) 18,749 (3) Income tax effect of non-GAAP adjustments 20,859 Adjusted income (Non-GAAP financial measure) $ 540,898 Net income per common share (GAAP financial measure): Basic $ 2.17 Diluted $ 2.17 Adjusted income per common share (Non-GAAP financial measure): Basic $ 1.97 Diluted $ 1.97 Average common shares outstanding: Basic 273,914 Diluted 274,421 Essential Utilities, Inc. and Subsidiaries Condensed Consolidated Balance Sheets (In thousands of dollars) (Unaudited) December 31, December 31, 2025 2024 Net property, plant and equipment 14,263,682 13,143,476 Current assets 610,396 485,911 Regulatory assets and other assets 4,590,767 4,397,167 19,464,845 18,026,554 Total equity 6,857,456 6,198,809 Long-term debt, excluding current portion, net of debt issuance costs and unamortized discount on debt 8,110,167 7,368,381 Current portion of long-term debt and loans payable 171,961 329,349 Other current liabilities 592,522 645,319 Deferred credits and other liabilities 3,732,739 3,484,696 19,464,845 18,026,554 Media Contact : David Kralle Vice President of Public Affairs Media Hotline: 1.877.325.3477 Media@Essential.co Investor Contact: Brian Dingerdissen Vice President, Treasurer, FP&A and IR O: 610.645.1191 BJDingerdissen@Essential.co
