EVERSOURCE ENERGY YEAR END 2021 RESULTS February 17, 2022 2021 Year - End Investor Call

EVERSOURCE ENERGY YEAR END 2021 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 business , b ut 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 generally accepted a cco unting principles (non - GAAP) that is calculated by dividing the net income or loss attributable to common shareholders of each business by the weighted average diluted Eversour ce Energy common shares outstanding for the period. Earnings discussions also include non - GAAP financial measures referencing 2021 earnings and EPS excluding charges at CL &P related to a settlement agreement that included credits to customers and funding of various customer assistance initiatives, and a storm performance penalty imposed on CL&P by PURA, and 2021 and 2020 earnings and EPS excluding certain acquisition and transition costs. Eversource Energy uses these non - GAAP financial measures to evaluat e and provide details of earnings results by business and to more fully compare and explain 2021 and 2020 results without including these items. This information is amon g t he primary indicators management uses as a basis for evaluating performance and planning and forecasting of future periods. Management believes the impacts of the CL&P set tlement agreement, the storm performance penalty imposed on CL&P by PURA, and acquisition and transition costs are not indicative of Eversource Energy’s ongoing costs an d performance. Management views these charges as not directly related to the ongoing operations of the business and therefore not an indicator of baseline operatin g p erformance. 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 prese ntation is a more meaningful representation of Eversource Energy’s financial performance and provides additional and useful information to readers in analyzing historica l a nd 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 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 statements” with in the meaning of the Private Securities Litigation Reform Act of 1995. Generally, readers can identify these forward - looking statements through the use of words or phr ases such as “estimate,” “expect,” “anticipate,” “intend,” “plan,” “project,” “believe,” “forecast,” “should,” “could” and other similar expressions. Forward - looking statements involve risks and uncertainties that may cause actual results or outcomes to differ materially from those included in the forward - looking statements. Factors that may cause a ctual results to differ materially from those included in the forward - looking statements include, but are not limited to: cyberattacks or breaches, including those resulting in the co mpromise of the confidentiality of our proprietary information and the personal information of our customers; disruptions in the capital markets or other events that make our a cce ss 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 policies, and customer demand and payment ability; ab ili ty or inability to commence and complete our major strategic development projects and opportunities; acts of war or terrorism, physical attacks or grid disturbances that may damage and disrupt our electric transmission and electric, natural gas, and water distribution systems; actions or inaction of local, state and federal regulatory, public pol icy and taxing bodies; substandard performance of third - party suppliers and service providers; fluctuations in weather patterns, including extreme weather due to climate change; cha nge s in business conditions, which could include disruptive technology or development of alternative energy sources related to our current or future business model; contamina tio n of, or disruption in, our water supplies; changes in levels or timing of capital expenditures; changes in laws, regulations or regulatory policy, including compliance with env iro nmental laws and regulations; changes 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 pr edict and contain uncertainties that may materially affect Eversource Energy’s actual results, many of which are beyond our control.
