Exhibit 99.3

2020 First 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 allocat ed to such business, but rather represent a direct interest in Eversource Energy's assets and liabilities as a whole. EPS by business is a non - GAAP (not determined using generall y accepted accounting principles) measure that is calculated by dividing the net income or loss attributable to common shareholders of each business by the wei ght ed average diluted Eversource Energy common shares outstanding for the period. Earnings discussions also include non - GAAP financial measures referencing 2020 earnin gs and EPS excluding certain acquisition costs and Q2 2019 earnings and EPS excluding the Northern Pass Transmission (NPT) impairment charge. Eversource Ene rgy uses these non - GAAP financial measures to evaluate and provide details of earnings results by business and to more fully compare and explain 2020 an d 2019 results without including these items. Management believes the acquisition costs and the NPT impairment charge are not indicative of Eversource Energy’s ong oin g costs and performance. Due to the nature and significance of these items on net income attributable to common shareholders, 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 anal yzi ng historical and future performance of the business. Non - GAAP financial measures should not be considered as alternatives to Eversource Energy’s consolidated net income a ttributable to common shareholders or EPS determined in accordance 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 on our customers, vendors, employees, regulators, and operations; changes in economic conditions, including impact on interest rates, tax policies, and customer demand and payment ab ility; ability or inability to commence and complete our major strategic development projects and opportunities, acts of war or terrorism, physical attacks or grid distu rba nces that may damage and disrupt our electric transmission and electric, natural gas, and water distribution systems; actions or inaction of local, state and fede ral regulatory, public policy and taxing bodies, substandard performance of third - party suppliers and service providers; fluctuations in weather patterns, including extreme weat her due to climate change; changes in business conditions, which could include disruptive technology or development of alternative energy sources related to our cu rre nt or future business model; contamination of, or disruption in, our water supplies; changes in levels or timing of capital expenditures, including the Columbia Gas of Mas sachusetts asset acquisition; changes in laws, regulations or regulatory policy, including compliance with environmental laws and regulations; changes in accounting standar ds 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 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.
