EVERSOURCE ENERGY Q2 2023 RESULTS August 1, 2023 2023 Second Quarter Results Exhibit 99.3

EVERSOURCE ENERGY Q2 2023 RESULTS 1 Safe Harbor Statement All per - share amounts in this presentation 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 prin cip les (non - GAAP) referencing earnings and EPS excluding the impairment charge for the offshore wind investment and certain transaction, transition and other charge s. 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 we igh ted average diluted Eversource Energy common shares outstanding for the period. The earnings and EPS of each business do not represent a direct legal intere st 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 us es 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 the se items. This information is among the primary indicators management uses as a basis for evaluating performance and planning and forecasting of future periods. Mana gem ent believes the impacts of the impairment charge for the offshore wind investment and transaction, transition and other charges are not indicative of Everso urc e Energy’s ongoing costs and performance. Management views these charges as not directly related to the ongoing operations of the business and therefore not an indicator of baseline operating performance. Due to the nature and significance of the effect of these items on net income attributable to common shareholder s a nd EPS, management believes that the non - GAAP presentation is a more meaningful representation of Eversource Energy’s financial performance and provides addition al and useful information to readers in analyzing historical and future performance of the business. These non - GAAP financial measures should not be considered as a lternatives to Eversource Energy’s reported net income attributable to common shareholders or EPS determined in accordance with GAAP as indicators of Eversource En ergy’s operating performance. This document includes statements concerning Eversource Energy’s expectations, beliefs, plans, objectives, goals, strategies, as sumptions of future events, future financial performance or growth and other statements that are not historical facts. These statements are “forward - looking statem ents” within the meaning of the Private Securities Litigation Reform Act of 1995. Generally, readers can identify these forward - looking statements through the use of w ords or phrases such as “estimate,” “expect,” “anticipate,” “intend,” “plan,” “project,” “believe,” “forecast,” “should,” “could” and other similar expressions. Fo rward - looking statements involve risks and uncertainties that may cause actual results or outcomes to differ materially from those included in the forward - looking statemen ts. Forward - looking statements are based on the current expectations, estimates, assumptions or projections of management and are not guarantees of future performa nce. These expectations, estimates, assumptions or projections may vary materially from actual results. Accordingly, any such statements are qualified in their entirety by reference to, and are accompanied by, the following important factors that may cause our actual results or outcomes to differ materially from those co ntained in our forward - looking statements, including, but not limited to: cyberattacks or breaches, including those resulting in the compromise of the confi den tiality of our proprietary information and the personal information of our customers; disruptions in the capital markets or other events that make our access to necessa ry capital more difficult or costly; changes in economic conditions, including impact on interest rates, tax policies, and customer demand and payment ability; ability or in ability to commence and complete our major strategic development projects and opportunities; the ability to sell Eversource’s 50 percent interest in three offshor e w ind projects under development on the timeline we expect, to satisfy the investment tax credit qualifications related to the tax equity investment in the South For k W ind project, and the ability of the Revolution Wind and Sunrise Wind projects to qualify for the investment tax credit adders, and to successfully reprice the Sunrise Wind ORE C contract; acts of war or terrorism, physical attacks or grid disturbances that may damage and disrupt our electric transmission and electric, natural gas, and wa ter distribution systems; actions or inaction of local, state and federal regulatory, public policy and taxing bodies; substandard performance of third - party suppliers and se rvice providers; fluctuations in weather patterns, including extreme weather due to climate change; changes in business conditions, which could include disruptive tec hno logy or development of alternative energy sources related to our current or future business model; contamination of, or disruption in, our water supplies; chang es in levels or timing of capital expenditures; changes in laws, regulations or regulatory policy, including compliance with environmental laws and regulations ; c hanges in accounting standards and financial reporting regulations; actions of rating agencies; and other presently unknown or unforeseen factors. Other risk factors are detailed in Eversource Energy’s reports filed with the Securities and Exchange Commission (SEC). They ar e updated as necessary and available on Eversource Energy’s website at www.eversource.com and on the SEC’s website at www.sec.gov. All such factors are difficult to predict and contain uncertainties that may materially affect Eversource Energy’s actual results, many of which are beyond our control. You should not place undue r eli ance on the forward - looking statements, as each speaks only as of the date on which such statement is made, and, except as required by federal securities la ws, Eversource Energy undertakes no obligation to update any forward - looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events.
