1 CenterPoint Energy reports strong Q3 2025 results; reiterates 2025 and 2026 full year guidance • Reports Q3 2025 earnings of $0.45 per diluted share on a GAAP basis and $0.50 per diluted share on a non-GAAP basis (“non-GAAP EPS”) • Reiterates its increased 2025 non-GAAP EPS guidance range of $1.75-$1.77, which, at the midpoint, represents 9% growth over full-year 2024 non-GAAP EPS1 • Reiterates its 2026 non-GAAP EPS guidance range of at least the midpoint of $1.89-$1.91, which at the midpoint, would represent 8% growth over the increased 2025 midpoint1 • Provides update on current demand growth, highlighting Houston Electric industrial throughput up over 17% as compared to the same period in 2024 Houston – October 23, 2025 - CenterPoint Energy, Inc. (NYSE: CNP) or “CenterPoint” today reported net income of $293 million, or $0.45 per diluted share on a GAAP basis for the third quarter of 2025, compared to $0.30 per diluted share in the comparable period of 2024. Non-GAAP EPS for the third quarter of 2025 was $0.50, over a 60% increase to the comparable quarter of 2024. These strong third quarter results were primarily driven by growth and regulatory recovery which contributed $0.07 per share of favorability and a significant reduction in O&M which contributed another $0.12 per share of favorability as compared to the third quarter of 2024. This favorability in O&M was primarily due to accelerated storm restoration work at Houston Electric in connection with severe storm activity in August of 2024 that did not repeat in 2025. In addition, other favorable drivers for the third quarter of 2025 as compared to the third quarter of 2024 were usage and other items of $0.01 and $0.03 per share, respectively. The $0.03 per share of favorability related to other items was primarily driven by a one-time benefit related to tax optimization. These drivers were partially offset by an unfavorable variance of $0.04 per share attributable to increased interest expense over the comparable quarter of 2024. 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 “We were proud to share our record $65 billion, 10-year capital investment plan last month and we continue to believe that CenterPoint Energy has one of the most differentiated growth stories in the entire industry. Moreover, we have customer-centric capital plans in each of our states to enhance safety, reliability and resiliency, while maintaining a strong focus on keeping bills affordable for customers. We look forward to continuing to deliver for all of our stakeholders both now and in the future,” said Jason Wells, Chair of the Board, President & CEO of CenterPoint. “The Greater Houston area is experiencing strong economic momentum, supported by one of the most diverse sets of growth drivers in the sector. It is not dependent on any single industry, and the impact is already visible. Throughput in our Houston Electric business is up 9% year-to-date, with industrial customer demand leading the way. Industrial throughput is up more than 17% quarter over quarter and over 11% year-to-date.” said Wells. “We look forward to finishing the year with strong execution and setting ourselves up for success in 2026 as we move into another full year of Greater Houston Resiliency Initiative work that will include close to $1 billion of System Resilience Plan spend as we continue to focus on building the most resilient coastal grid in the nation,” 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. Non-GAAP EPS guidance and 2024 and 2025 non-GAAP EPS • Non-GAAP EPS guidance and non-GAAP EPS 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 the announced sale of our Ohio natural gas LDC business; and • Non-GAAP EPS guidance and 2025 non-GAAP EPS also exclude impacts related to temporary emergency electric energy facilities (“TEEEF”) once they are no longer part of our rate-regulated business. In providing non-GAAP EPS guidance and non-GAAP EPS, 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 non-GAAP EPS guidance ranges also consider 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 non-GAAP EPS guidance range for any particular year 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.

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.
