For Immediate Release

CenterPoint Energy reports second quarter 2016 net loss of $0.01 per diluted share; $0.17 earnings per diluted share on a guidance basis

Houston, TX – August 5, 2016 - CenterPoint Energy, Inc. (NYSE: CNP) today reported a net loss of $2 million, or a loss of $0.01 per diluted share, for the second quarter of 2016, compared with net income of $77 million, or $0.18 per diluted share, for the same period of the prior year. On a guidance basis, second quarter 2016 earnings were $0.17 per diluted share, consisting of $0.14 from utility operations and $0.03 from midstream investments, compared with earnings of $0.19 per diluted share in the second quarter of 2015, consisting of $0.13 from utility operations and $0.06 from midstream investments.

Operating income for the second quarter of 2016 was $182 million, compared with $186 million in the second quarter of the prior year. Equity income from midstream investments was $31 million for the second quarter of 2016, compared with $43 million for the same period in the prior year.

“Throughput and customer growth remain strong for both of our utility businesses, and we remain on track to achieve our earnings guidance of $1.12 – $1.20 per share by year end,” said Scott M. Prochazka, president and chief executive officer of CenterPoint Energy. “Milder than normal weather at our electric utility and losses attributable to changes in the fair value of commodity derivatives at Enable Midstream accounted for most of the headwinds we experienced this quarter.”

REIT Review

As disclosed in February 2016, the company undertook a process to explore the use of a Real Estate Investment Trust (REIT) business model for all or part of the utility business. The company has completed its evaluation and decided not to pursue forming a REIT structure for its utility business, or any part thereof.

“Given a broad range of assumptions, we have determined that the potential to create long-term shareholder value by forming a REIT is very limited and does not justify exposure to the associated risks,” said Prochazka. “We continue to focus on increasing shareholder value by investing in our growing utility businesses.”

Electric Transmission & Distribution

The electric transmission & distribution segment reported operating income of $158 million for the second quarter of 2016, consisting of $135 million from the regulated electric transmission & distribution utility operations (TDU) and $23 million related to securitization bonds. Operating income for the second quarter of 2015 was $158 million, consisting of $131 million from the TDU and $27 million related to securitization bonds.

Operating income for the TDU benefited primarily from higher net transmission-related revenues ($8 million), customer growth ($8 million) and higher equity return ($5 million), primarily related to true-up proceeds. These benefits were partially offset by higher depreciation and other taxes ($12 million) as well as lower usage per customer, primarily due to milder weather ($4 million).

Natural Gas Distribution

The natural gas distribution segment reported operating income of $20 million for the second quarter of 2016, compared with $19 million for the same period of 2015. Operating income benefited from rate increases ($9 million) and customer growth ($2 million). These benefits were offset by higher depreciation and other taxes ($7 million) as well as increased contractor services expense ($5 million).

Energy Services

The energy services segment reported operating income of $-0- for the second quarter of 2016 compared with $9 million for the same period in the prior year. Second quarter operating income for 2016 included a mark-to-market accounting loss of $7 million, compared to a gain of $2 million for the same period of the prior year. Excluding mark-to-market adjustments, operating income would have been $7 million in both second quarter 2016 and second quarter 2015.

The second quarter of 2016 also included $2 million of operation and maintenance expenses and $1 million of amortization expenses related to the acquisition and integration of the retail energy services business and wholesale assets of Continuum Energy, which closed April 1, 2016.

Midstream Investments

The midstream investments segment reported $31 million of equity income for the second quarter of 2016, compared with $43 million in the second quarter of the prior year. Second quarter 2016 equity income from Enable Midstream was lower by $16 million versus the second quarter 2015 as a result of increased losses attributed to changes in the fair market value of commodity derivatives.

Enable Midstream also declared a quarterly cash distribution of $0.318 per common and subordinated unit on August 2, 2016. Please refer to Enable Midstream’s August 3, 2016 earnings press release for details.

ZENS-Related Impact

In connection with the merger between Charter Communications and Time Warner Cable, CenterPoint Energy received $100 and 0.4891 shares of Charter Common for each share of TWC Common held, resulting in cash proceeds of $178 million and 872,531 shares of Charter Common. In accordance with the terms of the Zero-Premium Exchangeable Subordinated Notes (ZENS), the company remitted $178 million to ZENS note holders in June 2016, which reduced contingent principal. As a result, the company recorded a pre-tax loss of $117 million, which is included in Loss on indexed debt securities on the Statements of Consolidated Income.

Dividend Declaration

On July 28, 2016, CenterPoint Energy’s board of directors declared a regular quarterly cash dividend of $0.2575 per share of common stock payable on September 9, 2016, to shareholders of record as of the close of business on August 16, 2016.

Outlook for 2016

On a consolidated basis, CenterPoint Energy reaffirms its guidance for 2016 in the range of $1.12 – $1.20 per diluted share.

The guidance range considers utility operations performance to date and certain significant variables that may impact earnings, such as weather, regulatory and judicial proceedings, throughput, commodity prices, effective tax rates, and financing activities. In providing this guidance, the company uses a non-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 of mark-to-market accounting in the company’s Energy Services business.

In providing guidance, the company assumes for midstream investments a 55.4 percent limited partner ownership interest in Enable Midstream and includes the amortization of CenterPoint Energy’s basis difference in Enable Midstream. CenterPoint Energy’s guidance takes into account such factors as Enable Midstream’s most recent public outlook for 2016, dated August 3, 2016, and effective tax rates. The company does not include other potential impacts such as any changes in accounting standards or Enable Midstream’s unusual items.

Use of Non-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 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. 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 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 2016 guidance is provided in this news release. 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 and mark-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 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 does not most accurately reflect the company’s fundamental business performance. These excluded items are reflected in the reconciliation table of this news release. CenterPoint Energy’s adjusted net income and adjusted diluted earnings per share non-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. These non-GAAP financial measures also may be different than non-GAAP financial measures used by other companies.
