CenterPoint Energy reports strong Q2 2021 earnings results

Houston - August 5, 2021 - CenterPoint Energy, Inc. (NYSE: CNP) today reported income available to common shareholders of $221 million, or $0.37 per diluted share, for the second quarter of 2021, compared to income available to common shareholders of $59 million, or $0.11 per diluted share, for the second quarter of 2020.

On a non-GAAP basis, second quarter 2021 earnings were $0.36 per diluted share, with $0.28 per diluted share from utility operations, and $0.08 per diluted share from midstream investments. This compared to $0.18 per diluted share from utility operations and $0.03 per diluted share from midstream investments in second quarter 2020. Both quarters included some one-time drivers. The second quarter 2020 Utility EPS included an unfavorable COVID-related impact of $0.06, while the second quarter 2021 Utility EPS included a favorable income tax benefit of $0.03. Other notable variances in Utility EPS for the quarter included $0.04 of favorable variance from organic growth and rate recovery, which was partially offset by a $0.02 impact attributable to the May 2020 equity issuance.

“CenterPoint’s six-month financial performance in 2021 has been strong,” said Dave Lesar, President and Chief Executive Officer of CenterPoint Energy. “We are raising our 2021 Utility EPS guidance range to $1.25-$1.27 per diluted share. This projected 8% growth in 2021 Utility EPS would put us at the high-end of our 6 to 8% Utility EPS annual growth target.”

Lesar added, “Regarding our capital investments, we have invested approximately $1.5 billion for the first six months of this year and are on track to invest approximately $3.4 billion for the full year 2021. These projects will add to the safety and reliability of our system for the benefit of our customers and our investors. Additionally, we now have better line of sight to additional capital investment opportunities beyond the 5-year, $16 billion investment plan we previously announced, including opportunities from the recent Texas legislative session.”

“While we are keen to discuss CenterPoint’s great future, we are planning to discuss exciting longer-term strategy updates at our Analyst Day which will take place on September 23^rd here in Houston. Through this forum, we plan to update investors on our longer-term business plan, earnings capacity, financial metrics, and net zero emissions targets,” said Dave Lesar.

Earnings Outlook

Given the recently announced merger between Enable and Energy Transfer, CenterPoint Energy will only be presenting a Utility EPS guidance range for 2021 as Enable did not provide 2021 guidance during its recent earnings call.

In addition to presenting its financial results in accordance with GAAP, including presentation of income (loss) available to common shareholders and diluted earnings (loss) per share, CenterPoint Energy provides guidance based on non-GAAP income and non-GAAP diluted earnings per share. 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.

Management evaluates CenterPoint Energy’s financial performance in part based on non-GAAP income and non-GAAP earnings per share. 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 of this news release, where applicable. CenterPoint Energy’s non-GAAP income and non-GAAP diluted earnings per share measures should be considered as a supplement to, and not as a substitute for, or superior to, income available to common shareholders 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.

(1) Utility EPS Guidance Range

2

In providing this guidance, CenterPoint Energy 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. The 2021 Utility EPS guidance range 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 diluted earnings per share 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.

(2) Midstream Investments EPS Expected Range

Midstream guidance is not initiated at this time as a result of a pending merger between Enable and Energy Transfer. CenterPoint Energy will continue to record its share of Enable’s earnings as well as basis difference accretion, earnings from the Enable preferred distributions net of an associated amount of debt, interest on the intercompany note between CenterPoint Energy and CenterPoint Energy Midstream, and an allocation of corporate overhead based on Midstream Investment segment’s relative earnings contribution until the transaction closes.

Upon closing of the transaction, CenterPoint Energy’s investment in Energy Transfer will be accounted for as an equity method investment with a fair value option. Following the closing of the transaction, CenterPoint Energy will establish Midstream Investments EPS expected range based on the distributions from Energy Transfer and the debt and corporate allocations previously described as a component of our Midstream Investments, excluding market-to-market gains or losses recorded for the Energy Transfer investments.

Additional information Use of Non-GAAP Financial Measures In this presentation and the oral statements made in connection herewith, CenterPoint Energy presents, based on diluted earnings per share, non-GAAP income and non-GAAP Utility earnings per share (“Utility EPS”), 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 2021 Utility EPS 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 income and Utility EPS. 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 income and Utility EPS 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 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.
