Exhibit 99.3

July 30, 2021 2021 Second Quarter Results

Safe Harbor Statement 1 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 and EPS of each business do not represent a direct legal interest in the assets and liabilities of such bu siness, but rather represent a direct interest in Eversource Energy's assets and liabilities as a whole. EPS by business is a financial measure not recognized under genera lly accepted accounting principles (non - GAAP) that is calculated by dividing the net income or loss attributable to common shareholders of each business by the weigh ted average diluted Eversource Energy common shares outstanding for the period. Earnings discussions also include a non - GAAP financial measure referencing 2021 and 2 020 earnings and EPS excluding certain acquisition and transition costs. Eversource Energy uses these non - GAAP financial measures to evaluate and provide deta ils of earnings results by business and to more fully compare and explain 2021 and 2020 results without including these items. Management believes the acquisition a nd transition costs are not indicative of Eversource Energy’s ongoing costs and performance. Due to the nature and significance of the effect of these items on net incom e 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 in analyzing historical and future performance of the business. These non - GAAP financial measures should not be considered as alternatives to Eversource Energy’s consolidated net income attributable to common shareholders or EPS determined in accor dan ce with GAAP as indicators of Eversource Energy’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. Factors that may cause actual results to differ materially from those included in the forward - looking statements include, but are not limited to: cyberattacks or breache s, including those resulting in the compromise of the confidentiality of our proprietary information and the personal information of our customers; disruptions in the capit al markets or other events that make our access to necessary capital more difficult or costly; the negative impacts of the novel coronavirus (COVID - 19) pandemic, including any new or emerging variants, on our customers, vendors, employees, regulators, and operations; changes in economic conditions, including impact on interest rates, tax polic ies , and customer demand and payment ability; ability or inability to commence and complete our major strategic development projects and opportunities; acts of wa r o r terrorism, physical attacks or grid disturbances that may damage and disrupt our electric transmission and electric, natural gas, and water distribution systems; ac tions or inaction of local, state and federal regulatory, public policy and taxing bodies; substandard performance of third - party suppliers and service providers; fluctuation s in weather patterns, including extreme weather due to climate change; changes in business conditions, which could include disruptive technology or development of al ter native energy sources related to our current or future business model; contamination of, or disruption in, our water supplies; changes in levels or timing of capi tal expenditures; changes in laws, regulations or regulatory policy, including compliance with environmental laws and regulations; changes in accounting standards and financia l r eporting 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 pr edict and contain uncertainties that may materially affect Eversource Energy’s actual results, many of which are beyond our control. You should not place undue relia nce 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 laws, Eversour ce 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.
