Exhibit 99.1 Eversource Energy Reports Second Quarter 2026 Results HARTFORD, Conn. and BOSTON, Mass. (July 30, 2026) – Eversource Energy (“Eversource” or the “Company”) (NYSE: ES) today reported GAAP earnings of $53.7 million, or $0.14 per share, for the second quarter of 2026, compared with GAAP and non-GAAP earnings of $352.7 million, or $0.96 per share, for the second quarter of 2025. Non-GAAP recurring earnings totaled $329.1 million1, or $0.87 per share1, in the second quarter of 2026. For the first half of 2026, Eversource reported GAAP earnings of $660.5 million, or $1.75 per share, compared with GAAP and non- GAAP earnings of $903.5 million, or $2.45 per share, for the first half of 2025. Non-GAAP recurring earnings totaled $979.8 million1, or $2.60 per share1, in the first half of 2026. GAAP results for the second quarter and first half of 2026 include a non-cash, after-tax charge of $111.4 million, or $0.30 per share, related to the sale of Aquarion Water Company on June 30, 2026 and an after-tax charge of $164.0 million, or $0.43 per share, related to an increase in Eversource's offshore wind contingent liability for expected future payments to Global Infrastructure Partners as part of the September 30, 2024 sale of the South Fork Wind and Revolution Wind projects. GAAP results for the first half of 2026 include an after- tax charge of $43.9 million, or $0.12 per share, related to estimated refunds associated with the Federal Energy Regulatory Commission (FERC) decision of March 19, 2026, that reduced the return on equity (ROE) rate for New England transmission owners from 10.57% to 9.57%. “During the second quarter, we completed our strategic divestiture of Aquarion Water, further strengthening our balance sheet and positioning Eversource for continued success as a pure-play regulated electric and natural gas delivery company. This focused strategy has already created new opportunities, including our preliminary selection by ISO-NE to develop critical transmission infrastructure that will bring power from northern Maine to southern New England. We are very pleased that the incumbent utilities have been selected for this important project.” said Joe Nolan, Chairman, President and CEO. “As we enter the second half of the year, our priorities remain clear: operating safely and efficiently, delivering reliable service to our customers, executing on our strategic investments and maintaining the financial strength that supports long-term value creation,” said Nolan. The Company reaffirms its revised earnings guidance for 2026 non-GAAP recurring earnings of between $4.57 per share1 and $4.72 per share1, which includes the impact of the prospective reduction to the transmission ROE rate resulting from the March 2026 FERC order and the absence of Aquarion earnings in the second half of the year. It also reaffirms its cumulative long-term earnings per share growth rate within the range of 5 to 7 percent through 2030, using the adjusted 2026 non-GAAP earnings guidance midpoint of $4.65 per share1 as the base year. Eversource expects annual earnings growth towards the upper half of its long-term guidance by 2028. Electric Transmission Eversource Energy’s transmission segment, excluding the FERC ROE refund charge noted above, earned $183.7 million in the second quarter of 2026 and $408.0 million1 in the first half of 2026, compared with earnings of $208.0 million in the second quarter of 2025 and $407.5 million in the first half of 2025. Transmission segment results in both periods reflect the impact from the reduction to the allowed ROE mentioned above, as well as higher interest expense, partially offset by continued investment in Eversource’s electric transmission system.

Electric Distribution Eversource Energy’s electric distribution segment earned $170.4 million in the second quarter of 2026 and $373.1 million in the first half of 2026, compared with earnings of $161.5 million in the second quarter of 2025 and $350.0 million in the first half of 2025. Improved results in both periods were due primarily to higher revenues from base distribution rate increases at Eversource’s Massachusetts and New Hampshire electric businesses, and continued investments in the Company’s distribution system. The higher revenues were partially offset by higher interest expense, depreciation, and property taxes. Natural Gas Distribution Eversource Energy’s natural gas distribution segment earned $29.7 million in the second quarter of 2026 and $325.1 million in the first half of 2026, compared with earnings of $35.3 million in the second quarter of 2025 and $253.7 million in the first half of 2025. Improved results in the first half were due primarily to base distribution rate increases at all of Eversource’s gas businesses, effective November 1, 2025, to recover continued investment in the Company’s natural gas infrastructure, partially offset by higher Operations and Maintenance (O&M), depreciation, property and income taxes, and interest expense. Lower results in the quarter were due primarily to the absence of a benefit in 2025 from previously expensed costs allowed for recovery. Water Distribution Eversource Energy’s water distribution segment, excluding the charge related to the sale of Aquarion noted above, earned $11.6 million1 in the second quarter of 2026 and $17.9 million1 in the first half of 2026, compared with earnings of $14.4 million in the second quarter of 2025 and $17.9 million in the first half of 2025. Lower results in the second quarter were due primarily to higher O&M and depreciation expense, partially offset by higher revenues. Eversource Parent and Other Companies Eversource Energy parent and other companies, excluding the increase in the offshore wind contingent liability noted above, had a loss of $66.3 million1 in the second quarter of 2026 and $144.3 million1 in the first half of 2026, compared with a loss of $66.5 million in the second quarter of 2025 and $125.6 million in the first half of 2025. Results in both periods were driven by higher interest expense and a higher effective tax rate.

Note: Eversource Energy will webcast a conference call with senior management on July 31, 2026, beginning at 9 a.m. Eastern Time. The webcast and associated slides can be accessed through Eversource Energy’s website at www.eversource.com or directly on the Investor Relations website at investors.eversource.com. 1 All per-share amounts in this news release are reported on a diluted basis. The only common equity securities that are publicly traded are common shares of Eversource Energy. The earnings discussion includes financial measures that are not recognized under generally accepted accounting principles (non-GAAP) referencing 2026 earnings and EPS excluding a charge on the sale of the Aquarion water distribution business, a charge associated with increasing the offshore wind contingent liability, and a charge related to the March 2026 FERC decision in the FERC base ROE complaints. EPS by business is also a non-GAAP financial measure and is calculated by dividing the Net Income Attributable to Common Shareholders of each business by the weighted average diluted Eversource Energy common shares outstanding for the period. The earnings and EPS of each business do not represent a direct legal interest in the assets and liabilities of such business, but rather represent a direct interest in Eversource Energy’s assets and liabilities as a whole. Eversource Energy uses these non-GAAP financial measures to evaluate and provide details of earnings results by business and to more fully compare and explain results without including these items. This information is among the primary indicators management uses as a basis for evaluating performance and planning and forecasting of future periods. Management believes the loss on the sale of the Aquarion water distribution business, the charge associated with increasing our offshore wind contingent liability, and the charge related to the March 2026 FERC decision in the FERC base ROE complaints are not indicative of Eversource Energy's ongoing costs and performance. Management views these charges as not directly related to the ongoing operations of the business and therefore not indicators of baseline operating performance. Due to the nature and significance of the effect of these items on Net Income Attributable to Common Shareholders and EPS, management believes that the non-GAAP presentation is a more meaningful representation of Eversource Energy's financial performance and provides additional and useful information to readers of this report in analyzing historical and future performance of the business. These non-GAAP financial measures should not be considered as alternatives to reported Net Income Attributable to Common Shareholders or EPS determined in accordance with GAAP as indicators of Eversource Energy's operating performance. Eversource Energy does not provide a reconciliation of guidance from non-GAAP recurring earnings or non-GAAP recurring EPS to the most directly comparable GAAP measures because it is not able to predict with reasonable certainty the amount or nature of all items that will be included in Net Income Attributable to Common Shareholders or EPS for the year ending December 31, 2026. These items are uncertain, depend on many factors and could have a material impact on Net Income Attributable to Common Shareholders and EPS for the year ending December 31, 2026, and therefore cannot be made available without unreasonable effort.
