Houston – Feb. 16, 2021—CenterPoint Energy, Inc. (NYSE: CNP) today announced support for the merger between Enable Midstream Partners, LP (NYSE: ENBL) and Energy Transfer LP (NYSE: ET), which will result in an exchange of its investment in Enable Midstream Partners, LP in an at market, unit-for-unit transaction. CenterPoint Energy currently owns 53.7 percent of the common units representing limited partner interests in Enable, a publicly traded master limited partnership that owns, operates and develops strategically located natural gas and crude oil infrastructure assets.

At closing, Energy Transfer will acquire 100% of Enable’s outstanding equity interests, resulting in the exchange of CenterPoint Energy’s Enable common units at the transaction exchange ratio of 0.8595x Energy Transfer common units for each Enable common unit. CenterPoint Energy will also receive $5 million in cash in exchange for its Enable general partner interest and approximately $385 million of Energy Transfer Series G Fixed-Rate Reset Cumulative Redeemable Perpetual Preferred units in exchange for $363 million of Enable Series A Fixed-to-Floating Non-Cumulative Redeemable Perpetual Preferred units owned by CenterPoint Energy. CenterPoint Energy is under no obligation to retain the

Energy Transfer common or preferred units issued by Energy Transfer after transaction close. Upon the consummation of the transaction, the partnership agreements between CenterPoint Energy and OGE will terminate, and CenterPoint Energy will pay $30 million to OGE. CenterPoint Energy expects its total transaction related expenses to be $45 million, which is inclusive of legal, financial advisory, and the $30 million payment.

“I could not be more excited to share this announcement today. This transaction aligns with our new long-term growth strategy and gives us the ability to accelerate our transition to a fully regulated business. We are now on an accelerated path to reducing our exposure to the volatility of the midstream industry, while supporting our ability to deliver utility guidance basis earnings per share growth of 6%-8% and grow annual rate base at 10%. This transaction will support our previously announced 2021 guidance basis utility EPS range of $1.23—$1.25,” said President and CEO Dave Lesar. “As I shared during our Investor Day, our path to eliminating midstream exposure would be achieved by using a disciplined financial approach. The transaction with Energy Transfer will position us well to execute on that objective by putting us in a more secure and liquid security. Energy Transfer’s scale and desirable portfolio of take-or-pay contracts will be credit accretive for CenterPoint Energy and de-risk any future distribution yield as we exit midstream. Additionally, we believe that the termination of our partnership will provide us with more autonomy to exit midstream with better economics and at a faster pace, which will benefit our shareholders.”

Lesar added, “We are committed to delivering on a growth strategy that prioritizes investments in our premium, core regulated utility businesses that will make up more than 90% of our earnings as we take steps to exit midstream. Our strategy also supports a transition to a cleaner energy future that will drive industry-leading growth. We believe our strategy will enable us to grow our utilities and maximize the advantages of this growth for our stakeholders. We look forward to announcing our 2020 fourth-quarter and year-end financial results during our earnings call on February 25th.”

The transaction is expected to be completed in the second half of 2021, subject to customary closing conditions, including Hart-Scott-Rodino antitrust clearance.

The proposed merger between Energy Transfer and Enable has been in the works for some time and has not impacted the efforts of CenterPoint to quickly restore power to the regions it serves. Please refer to our weather and restoration related updates as they become available.

Use of Non-GAAP Measures

As included in this press release, guidance basis utility earnings per share (“Utility EPS”) is not a generally accepted accounting principles (“GAAP”) financial measure. 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 Utility EPS guidance range reflects dilution and earnings as if the Company’s Series B Preferred Stock converted on their mandatory conversion date. Utility EPS guidance range 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, regulatory and judicial proceedings. In addition, the 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 Utility EPS guidance range may not be met and our projected annual Utility EPS growth rate range may change. Utility EPS includes an allocation of corporate overhead based upon our Utility segments relative earnings contribution. Corporate overhead consists primarily of interest expense, preferred stock dividend requirements and other items directly attributable to the parent along with associated income taxes, and considers certain significant variables that may impact earnings. Utility EPS excludes (a) earnings or losses from the change in value of the Company’s 2.0% Zero-Premium Exchangeable Subordinated Notes due 2029 (“ZENS”) and related securities, (b) certain expenses associated with merger integration, and (c) Midstream Investments, including income from the Enable preferred units and a corresponding amount of debt in addition to an associated allocation of corporate overhead based on relative earnings contribution. Utility EPS guidance also does not include other potential impacts, such as changes in accounting standards, impairments or unusual items, which could have a material impact on GAAP reported results

for the applicable guidance period. CenterPoint Energy is unable to present a quantitative reconciliation of forward-looking Utility EPS because changes in the value of ZENS and related securities, future impairments and other unusual items are not estimable as they are highly variable and difficult to predict due to various factors outside of management’s control. Management evaluates CenterPoint Energy’s financial performance in part based on Utility EPS. Management believes that presenting this non-GAAP financial measure 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 this non-GAAP financial measure exclude items that Management believes does not most accurately reflect the Company’s fundamental business performance. CenterPoint Energy’s Utility EPS non-GAAP financial measure should be considered as a supplement to, and not as a substitute for, or superior to, diluted earnings per share, which is the most directly comparable GAAP financial measure. This non-GAAP financial measure also may be different than non-GAAP financial measures used by other companies
