1 CenterPoint Energy reports solid Q2 2025 results; reiterates 2025 full year guidance; increases 10-year capital investment plan by $500MM • Reports Q2 2025 earnings of $0.30 per diluted share on a GAAP basis and $0.29 per diluted share on a non-GAAP basis (“non-GAAP EPS”) • Increases 2025 and 10-year capital investment plan by $500 million without the anticipated need for incremental equity • $500 million capital investment increase is the third increase this year, totaling $5.5 billion, and bringing the 10-year plan to $53 billion through 2030 • Provides update that current interconnection queue is up ~6GWs since the 2025 first quarter earnings call, strengthening conviction in 50% load growth forecast by 2031 • Reiterates 2025 non-GAAP EPS guidance range of $1.74-$1.76, which, at the midpoint, represents 8% growth over full-year 2024 non-GAAP EPS and further maintains non-GAAP EPS growth target of the mid-to-high end of 6%-8% annually thereafter through 20301 • Accomplished all state and public commitments related to Phase II of the Greater Houston Resiliency Initiative ahead of schedule and prior to start of 2025 hurricane season Houston – July 24, 2025 - CenterPoint Energy, Inc. (NYSE: CNP) or “CenterPoint” today reported net income of $198 million, or $0.30 per diluted share on a GAAP basis for the second quarter of 2025, compared to $0.36 per diluted share in the comparable period of 2024. Non-GAAP EPS for the second quarter of 2025 was $0.29, versus $0.36 for the comparable quarter of 2024. These second quarter results include an unfavorable variance of $0.01 per share attributable to growth and rate recovery. This lower relative impact was driven by the timing of recoveries from interim capital mechanisms not available during recent rate case activity that is now largely completed. 1 CenterPoint is unable to present a quantitative reconciliation of forward-looking non-GAAP diluted earnings per share without unreasonable effort because changes in the value of ZENS (as defined herein) 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 Additional unfavorable items for the quarter include increased financing costs of $0.03 per share and increased operating and maintenance expense of $0.03 per share. Weather and usage were favorable, contributing $0.01 per share when compared to the second quarter of 2024. “I’m incredibly proud of our teams as they have worked to deliver about a year and a half’s worth of work since last summer as part of the Greater Houston Resiliency Initiative. We’ve met all of our Phase II public commitments on- time or ahead of schedule, and we are on a positive path forward as we work to build and operate the most resilient coastal grid in the nation. Our customers are already seeing the benefits with nearly 50% less outage minutes in the first six months of 2025 compared to 2024. This is great progress, and we aren’t done yet,” said Jason Wells, President & CEO of CenterPoint. “While our focus has been on resiliency, we are not losing sight of the incredible pace of diverse growth our service territories continue to experience, especially those in Texas. This year alone we have increased our capital investment plan by $5.5 billion, including the $500 million increase we announced today,” continued Wells. “Even though we are taking a conservative approach to this growth, we continue to see an upward bias towards investment opportunities that are not yet reflected in our current plan. We believe these opportunities, combined with our ability to efficiently finance and a lighter regulatory calendar over the next few years, are strong tailwinds that we will incorporate into our refreshed 10-year plan that we’re excited to share by the end of September,” said Wells.

3 Earnings Outlook In addition to presenting its financial results in accordance with GAAP, including presentation of net income (loss) and diluted earnings (loss) per share, CenterPoint 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’s financial performance in part based on non-GAAP income and non-GAAP diluted earnings per share. Management believes that presenting these non-GAAP financial measures enhances an investor’s understanding of CenterPoint’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’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, 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. 2024 and 2025 non-GAAP EPS and 2025 non-GAAP EPS guidance range • 2024 and 2025 non-GAAP EPS and 2025 non-GAAP EPS guidance excludes: ◦ Earnings or losses from the change in value of CenterPoint’s 2.0% Zero-Premium Exchangeable Subordinated Notes due 2029 (“ZENS”) and related securities; ◦ Gains, losses and impacts, including related expenses, associated with mergers and divestitures, such as the divestiture of our Louisiana and Mississippi natural gas LDC businesses; and • 2025 non-GAAP EPS and 2025 non-GAAP EPS guidance also exclude impacts related to temporary emergency electric energy facilities (“TEEEF”) once they are no longer part of our rate-regulated business. In providing 2024 and 2025 non-GAAP EPS and 2025 non-GAAP EPS guidance, CenterPoint 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 2025 non-GAAP 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. To the extent actual results deviate from these assumptions, the 2025 non-GAAP EPS guidance range may not be met, or the projected annual non-GAAP EPS growth rate may change. CenterPoint is unable to present a quantitative reconciliation of forward-looking non-GAAP diluted earnings per share without unreasonable effort 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.

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.

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 (loss) and diluted earnings (loss) per share, the Company also provides guidance based on non-GAAP income and non-GAAP diluted earnings per share and also provides non-GAAP funds from operations / non-GAAP rating agency adjusted debt (“FFO/Debt”). 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. Please refer to the Appendix for detailed discussion of the use of non-GAAP financial measures presented herein. Cautionary Statement and Other Disclaimer
