2019 Year - End Investor Call February 20, 2020

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 liabi lit ies allocated to such business, but rather represent a direct interest in Eversource Energy's assets and liabilities as a whole. EPS by business i s a non - GAAP (not determined using generally accepted accounting principles) measure that is calculated by dividing the net income or loss attributable to co mmon shareholders of each business by the weighted average diluted Eversource Energy common shares outstanding for the period. Earnings discussions al so include non - GAAP financial measures referencing 2019 earnings and EPS excluding the NPT impairment charge. 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 2019 results w ith out including the impact of the NPT impairment charge. Management believes the NPT impairment charge is not indicative of Eversource Energy’s ongoing pe rformance. Due to the nature and significance of the NPT impairment charge on net income attributable to common shareholders, management believ es that the non - GAAP presentation is a more meaningful representation of Eversource Energy’s financial performance and provides additional and use ful information to readers in analyzing historical and future performance of the business.
