This presentation and the oral statements made in connection herewith contain statements concerning CenterPoint Energy, Inc.’s (“our,” “CenterPoint Energy,” or the “Company”)expectations, beliefs, plans, objectives, goals, strategies, future operations, events, financial position, earnings, growth, costs, prospects, capital investments or performance or underlying assumptions (including future regulatory filings and recovery, liquidity, capital resources, balance sheet, cash flow, capital investments and management, financing costs, and rate base or customer growth) and other statements that are not historical facts. These statements are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. You should not place undue reliance on forward-looking statements. Actual results may differ materially from those expressed or implied by these statements. You can generally identify our forward-looking statements by the words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “goal,” “intend,” “may,” “objective,” “plan,” “potential,” “predict,” “projection,” “should,” “target,” “will,” or other similar words. The absence of these words, however, does not mean that the statements are not forward-looking. Examples of forward-looking statements in this presentation include statements about our intentions with respect to our ownership interest in Enable Midstream Partners, LP (“Enable”), our expectation from Enable’s financial performance and its effect on the Company, our anticipated growth and guidance (including earnings, dividend, dividend payout ratio and core operating income growth), equity issuances, credit metrics and credit ratings, future financing plans and expectation for liquidity and capital resources, expenditures and recovery, average rate base and rate base growth, customer growth, adjusted funds from operations (“FFO”), implications resulting from enacted tax legislation (including the impact on regulatory treatment, deferred taxes, customer rates and adjusted FFO and debt) and effective tax rates, our anticipated regulatory filings and recovery mechanisms and Energy Services’ operating income target for 2018, among other statements. We have based our forward-looking statements on our management’s beliefs and assumptions based on information currently available to our management at the time the statements are made. We caution you that assumptions, beliefs, expectations, intentions, and projections about future events may and often do vary materially from actual results. Therefore, we cannot assure you that actual results will not differ materially from those expressed or implied by our forward-looking statements. Some of the factors that could cause actual results to differ from those expressed or implied by our forward-looking statements include but are not limited to the timing and impact of future regulatory, legislative and IRS decisions, financial market conditions, future market conditions, economic and employment conditions, customer growth, Enable’s performance and ability to pay distributions, and other factors described in the Company’s Form 10-K for the period ended December 31, 2017 under “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Certain Factors Affecting Future Earnings” and in other filings with the Securities and Exchange Commission (“SEC”) by the Company, which can be found at www.centerpointenergy.com on the Investor Relations page or on the SEC’s website at www.sec.gov. Slide 18 is derived from Enable’s investor presentation as presented during its Q4 and full year 2017 earnings call dated February 20, 2018. This slide is included for informational purposes only. The content has not been verified by us, and we assume no liability for the same. You should consider Enable’s investor materials in the context of its SEC filings and its entire investor presentation, which is available on is website at http://investors.enablemidstream.com/. This presentation contains time sensitive information that is accurate as of the date hereof (unless otherwise specified as accurate as of another date). Some of the information in this presentation is unaudited and may be subject to change. We undertake no obligation to update the information presented herein except as required by law. Investors and others should note that we may announce material information using SEC filings, press releases, public conference calls, webcasts and the Investor Relations page of our website. In the future, we will continue to use these channels to distribute material information about the Company and to communicate important information about the Company, key personnel, corporate initiatives, regulatory updates and other matters. Information that we post on our website could be deemed material; therefore, we encourage investors, the media, our customers, business partners and others interested in our Company to review the information we post on our website. Use of Non-GAAP Financial Measures In addition to presenting its financial results in accordance with generally accepted accounting principles (“GAAP”), including presentation of net income, diluted earnings per share and net cash provided by operating activities, the Company also provides guidance based on adjusted net income and adjusted diluted earnings per share and provides adjusted FFO, which are non-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. The Company’s adjusted net income and adjusted diluted earnings per share calculation excludes from net income and diluted earnings per share, respectively, the impact of ZENS and related securities and mark-to-market gains or losses resulting from the Company’s Energy Services business. A reconciliation of net income and diluted earnings per share to the basis used in providing guidance is provided in this presentation on slide 28. The Company is unable to present a quantitative reconciliation of forward-looking adjusted net income and adjusted diluted earnings per share because changes in the value of ZENS and related securities and mark-to-market gains or losses resulting from the Company’s Energy Services business are not estimable. The Company’s adjusted FFO calculation excludes from net cash provided by operating activities the impact of changes in (i) other assets and liabilities (accounts receivable and unbilled revenues, net; inventory; taxes receivable; accounts payable; fuel cost recovery; non-trading derivatives, net; margin deposits, net; interest and taxes accrued; net regulatory assets and liabilities; other current assets; other current liabilities; other assets; and other liabilities), (ii) other, net, and (iii) amounts associated with transition and system restoration bond companies, and includes distributions from unconsolidated affiliates in excess of cumulative earnings. Management evaluates the Company’s financial performance in part based on adjusted net income, adjusted diluted earnings per share and adjusted FFO. We believe that presenting these non-GAAP financial measures enhances an investor’s understanding of the Company’s overall financial performance by providing them with an additional meaningful and relevant comparison of current and anticipated future results across periods. Management believes the adjustments made in these non-GAAP financial measures exclude or include items, as applicable, to most accurately reflect the Company’s business performance. These excluded or included items, as applicable, are reflected in the reconciliation tables on slides 26, 27, and 28 and the adjusted FFO calculations on slides 24 and 25 of this presentation. The Company’s adjusted net income, adjusted diluted earnings per share and adjusted FFO non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, net income, 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. Cautionary Statement
