CenterPoint Energy reports third quarter 2018 earnings of $0.35 per diluted

share; $0.39 earnings per diluted share on a guidance basis, excluding

impacts associated with the pending merger with Vectren

Company anticipates achieving the high end of its $1.50-$1.60 2018 EPS guidance range,

Houston—Nov. 8, 2018—CenterPoint Energy, Inc. (NYSE: CNP) today reported net income available to common shareholders of $153 million, or $0.35 per diluted share, for the third quarter of 2018, compared with $169 million, or $0.39 per diluted share for the third quarter of 2017. On a guidance basis, and excluding impacts associated with the pending merger with Vectren, third quarter 2018 earnings were $0.39 per diluted share, consisting of $0.25 from utility operations and $0.14 from midstream investments. Third quarter 2017 earnings on a guidance basis were $0.38 per diluted share, consisting of $0.28 from utility operations and $0.10 from midstream investments.

Operating income for the third quarter of 2018 was $226 million, compared with $297 million in the third quarter of 2017. For the third quarter of 2017 operating income was increased and other income decreased by $18 million in accordance with the retrospective adoption earlier this year of the accounting standard for compensation-retirement benefits (ASU2017-07). Equity income from midstream investments was $81 million for the third quarter of 2018, compared with $68 million for the third quarter of 2017.

“Our businesses performed well this quarter, in line with our expectations, and we remain on track to achieve the high end of our EPS guidance range,” said Scott M. Prochazka, president and chief executive officer of CenterPoint Energy. “In addition, the remaining approvals required for our pending merger with Vectren are on schedule, and we expect the transaction to be completed in the first quarter of 2019.”

Business Segments

Electric Transmission & Distribution

The electric transmission & distribution segment reported operating income of $227 million for the third quarter of 2018, consisting of $214 million from the regulated electric transmission & distribution utility operations (TDU) and $13 million related to securitization bonds. Operating income for the third quarter of 2017 was $254 million, consisting of $236 million from the TDU and $18 million related to securitization bonds.

-more- 1

Operating income for the TDU benefited primarily from rate relief, customer growth and higher equity return related to the annualtrue-up of transition charges. These benefits were more than offset by higher operation and maintenance expenses, lower revenues reflecting the lower federal income tax rate due to the Tax Cuts and Jobs Act (TCJA), and higher depreciation and amortization expense.

The retrospective adoption of ASU2017-07 resulted in an increase to TDU operating income and a corresponding decrease to other income of $7 million for the third quarter of 2017.

Natural Gas Distribution

The natural gas distribution segment reported operating income of $3 million for the third quarter of 2018, compared with $25 million for the third quarter of 2017. Operating income benefited from rate relief and weather and usage, driven by the timing of a decoupling mechanism in Minnesota. These increases were more than offset by higher operation and maintenance expenses, higher depreciation and amortization expense and lower revenues reflecting the lower federal income tax rate due to the TCJA.

The retrospective adoption of ASU2017-07 resulted in an increase to natural gas distribution operating income and a corresponding decrease to other income of $5 million for the third quarter of 2017.

Energy Services

The energy services segment reported an operating loss of $9 million for the third quarter of 2018, which included amark-to-market gain of $1 million, compared with operating income of $7 million for the third quarter of 2017, which included amark-to-market gain of $2 million. Excludingmark-to-market adjustments, the operating loss was $10 million for the third quarter of 2018 compared with operating income of $5 million for the third quarter of 2017. Operating income decreased due to lower margin, resulting from reduced opportunities to optimize natural gas supply costs and timing impacts related to natural gas storage activity, and higher operation and maintenance expense. Energy Services remain on track to achieve their core operating income target of $70-$80 million for 2018.

Midstream Investments

The midstream investments segment reported $81 million of equity income for the third quarter of 2018, compared with $68 million in the third quarter of 2017.

Other Operations

The other operations segment reported operating income of $5 million for the third quarter of 2018, compared with operating income of $11 million in the third quarter of 2017. This decrease is primarily due to costs related to the pending merger with Vectren.

Earnings Outlook

CenterPoint Energy anticipates achieving the high end of the $1.50-$1.60 EPS guidance range for 2018, excluding impacts associated with the pending merger with Vectren. These impacts include integration planning and transaction-related fees and expenses. In addition, the company has issued $5.2 billion of debt and equity securities to fund the pending merger with Vectren. Therefore, 2018 is expected to have higher net interest expense and a higher common stock share count, the effects of which are not included in the 2018 EPS guidance range set forth above. This guidance is inclusive of Enable’s 2018 net income guidance. The guidance range assumes ownership of 54.0 percent of the common units representing limited partner interests in Enable Midstream and includes the amortization of CenterPoint Energy’s basis differential in Enable Midstream and effective tax rates. CenterPoint Energy does not include other potential Enable Midstream impacts on guidance, such as any changes in accounting standards or unusual items.

The guidance range considers utility operations performance to date and certain significant variables that may impact earnings, such as weather, throughput, commodity prices, effective tax rates, financing activities (other than those to fund the pending merger with Vectren), and regulatory and judicial proceedings to include regulatory action as a result of recent tax reform legislation.

Utility operations EPS includes all earnings except those related to Midstream Investments (utility operations EPS includes the Enable Series A Preferred Units).

In providing this guidance, CenterPoint Energy uses anon-GAAP measure of adjusted diluted earnings per share that does not consider other potential impacts, such as changes in accounting standards or unusual items, earnings or losses from the change in the value of the ZENS securities and the related stocks, or the timing effects ofmark-to-market accounting in the company’s energy services business. CenterPoint Energy’s guidance does not currently reflect impacts associated with the pending merger with Vectren.

Risks Related to the Merger

Important factors that could cause actual results to differ materially from those indicated by the provided forward-looking information include risks and uncertainties relating to: (1) the risk that CenterPoint Energy or Vectren may be unable to obtain regulatory approvals required for the proposed transactions, or that required regulatory approvals or agreements with other parties interested therein may delay the proposed transactions or may be subject to or impose adverse conditions or costs, (2) the occurrence of any event, change or other circumstances that could give rise to the termination of the proposed transactions or could otherwise cause the failure of the proposed transactions to close, (3) the risk that a condition to the closing of the proposed transactions may not be satisfied, (4) the outcome of any legal proceedings, regulatory proceedings or enforcement matters that may be instituted relating to the proposed transactions, (5) the receipt of an unsolicited offer from another party to acquire assets or capital stock of Vectren that could interfere with the proposed transactions, (6) the timing to consummate the proposed transactions, (7) the costs incurred to consummate the proposed transactions, (8) the possibility that the expected cost savings,

-more- 6

synergies or other value creation from the proposed transactions will not be realized, or will not be realized within the expected time period, (9) the risk that the companies may not realize fair values from properties that may be required to be sold in connection with the merger, (10) the credit ratings of the companies following the proposed transactions, (11) disruption from the proposed transactions making it more difficult to maintain relationships with customers, employees, regulators or suppliers, and (12) the diversion of management time and attention on the proposed transactions.

Use ofNon-GAAP Financial Measures by CenterPoint Energy in Providing Guidance

In addition to presenting its financial results in accordance with generally accepted accounting principles (GAAP), including presentation of net income and diluted earnings per share, CenterPoint Energy also provides guidance based on adjusted net income and adjusted diluted earnings per share, which arenon-GAAP financial measures. Generally, anon-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. CenterPoint Energy’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 andmark-to-market gains or losses resulting from the company’s Energy Services business. CenterPoint Energy’s guidance does not currently reflect impacts associated with the pending merger with Vectren. CenterPoint Energy 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 andmark-to-market gains or losses resulting from the company’s Energy Services business are not estimable.

Management evaluates the company’s financial performance in part based on adjusted net income and adjusted diluted earnings per share. We believe that presenting thesenon-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 thesenon-GAAP financial measures exclude items that Management believes does not most accurately reflect the company’s fundamental business performance. These excluded items are reflected in the reconciliation tables of this news release, where applicable. CenterPoint Energy’s adjusted net income and adjusted diluted earnings per sharenon-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, net income and diluted earnings per share, which respectively are the most directly comparable GAAP financial measures. Thesenon-GAAP financial measures also may be different thannon-GAAP financial measures used by other companies.
