ADDITIONAL INFORMATION Use of Non-GAAP Financial Measures In this presentation and the oral statements made in connection herewith, CenterPoint Energy presents non-GAAP Utility net income, non-GAAP Utility earnings per share (“Utility EPS”) and non-GAAP long-term funds from operations (“FFO”) which are not generally accepted accounting principles (“GAAP”) financial measures. Generally, a non-GAAP financial measure is a numerical measure of a company’s historical or future financial performance that excludes or includes amounts that are not normally excluded or included in the most directly comparable GAAP financial measure. 2021 Utility EPS includes net income from Electric and Natural Gas segments, as well as after tax Corporate and Other operating income and an allocation of corporate overhead based upon the Utility’s relative earnings contribution. Corporate overhead consists primarily of interest expense, preferred stock dividend requirements, and other items directly attributable to the parent along with the associated income taxes. Utility EPS excludes (a) earnings or losses from the change in value of CenterPoint Energy's 2.0% Zero-Premium Exchangeable Subordinated Notes due 2029 (“ZENS”) and related securities, (b) certain expenses associated with Vectren merger integration, (c) Midstream Investments segment and associated income from the Enable preferred units and a corresponding amount of debt in addition to an allocation of associated corporate overhead and impact, including related expenses, associated with the merger between Enable and Energy Transfer, (d) cost associated with the early extinguishment of debt and (e) gain and impact, including related expenses, associated with gas LDC sales. 2021 Utility EPS does not consider the items noted above and other potential impacts, such as changes in accounting standards, impairments or other unusual items, which could have a material impact on GAAP reported results for the applicable guidance period. 2021 Utility EPS also considers assumptions for certain significant variables that may impact earnings, such as customer growth and usage including normal weather, throughput, recovery of capital invested, effective tax rates, financing activities and related interest rates and regulatory and judicial proceedings. In addition, the 2021 Utility EPS guidance range assumes a continued re-opening of the economy in CenterPoint Energy's service territories throughout 2021.To the extent actual results deviate from these assumptions, the 2021 Utility EPS guidance range may not be met or the projected annual Utility EPS growth rate may change. CenterPoint Energy is unable to present a quantitative reconciliation of forward-looking non-GAAP Utility net income, Utility EPS and long- term FFO because changes in the value of ZENS and related securities, future impairments and other unusual items are not estimable and are difficult to predict due to various factors outside of management’s control. The appendix to this presentation contains a reconciliation of income (loss) available to common shareholders and diluted earnings (loss) per share to the basis used in providing guidance. Management evaluates the Company’s financial performance in part based on non-GAAP Utility net income, Utility EPS and long-term FFO. Management believes that presenting these non-GAAP financial measures enhances an investor’s understanding of CenterPoint Energy’s overall financial performance by providing them with an additional meaningful and relevant comparison of current and anticipated future results across periods. The adjustments made in these non-GAAP financial measures exclude items that Management believes do not most accurately reflect the Company’s fundamental business performance. These excluded items are reflected in the reconciliation tables, where applicable. CenterPoint Energy’s non-GAAP Utility net income, Utility EPS and long-term FFO, which are non-GAAP financial measures, should be considered as a supplement to, and not as a substitute for, or superior to, income available to common shareholders, diluted earnings per share, and net cash provided by operating activities which, respectively, are the most directly comparable GAAP financial measures. These non-GAAP financial measures also may be different than non-GAAP financial measures used by other companies. Net Zero Disclaimer While we believe that we have a clear path towards achieving our net zero emissions (Scope 1 and Scope 2) by 2035 goals, our analysis and path forward required us to make a number of assumptions. These goals and underlying assumptions involve risks and uncertainties and are not guarantees. Should one or more of our underlying assumptions prove incorrect, our actual results and ability to achieve net zero emissions by 2035 could differ materially from our expectations. Certain of the assumptions that could impact our ability to meet our net zero emissions goals include: emission levels, service territory size and capacity needs remaining in line with Company expectations (inclusive of changes related to the sale of our natural gas businesses in Arkansas and Oklahoma); regulatory approval of our generation transition plan; impacts of future environmental regulations or legislation; impacts of future carbon pricing regulation or legislation; price and availability of carbon offsets; price of fuel, such as natural gas; cost of energy generation technologies, such as wind and solar, natural gas and storage solutions; adoption of alternative energy by the public, including adoption of electric vehicles; rate of technology innovation with regards to alternative energy resources; our ability to implement our modernization plans for our pipelines and facilities; retirement dates of our coal facilities by 2035; and enhancement of energy efficiencies.
