CenterPoint Energy reports strong Q2 2026 results; provides update on ERCOT’s Batch

Zero process; increases 10-year capital plan; reiterates full-year 2026 guidance

·Reports Q2 2026 earnings of $0.37 per diluted share on a GAAP basis and $0.40 per diluted share on a non-GAAP basis (“non-GAAP EPS”)

·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 2025 delivered results 1

·Highlights over 17 gigawatts of Batch Zero submissions, of which approximately 14 gigawatts are expected to be eligible as base load or studied load

·Increases 10-year capital investment plan by $1.2 billion without increasing current equity financing guide; 10-year capital investment plan now totals $66.7 billion

Houston – July 28, 2026 – CenterPoint

Energy, Inc. (NYSE: CNP), or “CenterPoint,” today reported net income of $244 million, or $0.37 per diluted share, on a GAAP basis for the second quarter of 2026, compared to $0.30 per diluted share in the comparable period of 2025.

Non-GAAP EPS for the second quarter of 2026 was $0.40

per diluted share, compared to $0.29 per diluted share in the comparable period of 2025. These strong second quarter results were primarily driven by growth and regulatory recovery, which contributed $0.10 per share of favorability compared to the second quarter of 2025. O&M contributed $0.02 per share of favorable variance compared to last year. These drivers were partially offset by $0.01 per share of unfavorable weather and usage and $0.01 per share of unfavorability from increased interest expense over the comparable quarter of 2025. Lastly, other items contributed $0.01 per share of favorable variance when compared to the second quarter of 2025. This variance was primarily related to the amortization of deferred equity in connection with previous storm securitizations which was partially offset by other taxes and equity dilution.

CenterPoint increased its 10-year capital investment plan by $1.2 billion to $66.7 billion of planned investment from 2026 through 2035, reflecting incremental investment to support accelerating demand from large load customers in Houston, as well as refined investment estimates for the Downtown Houston Revitalization project.

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.

The company also announced that it submitted over 17 gigawatts of large load projects through ERCOT’s Batch Zero process, of which approximately 14 gigawatts are expected to be eligible as base load or studied load. In the aggregate, these approximately 14 gigawatts of projects would represent more than a 65% increase from our current Houston Electric peak system demand of 21 gigawatts.

“As part of our industry’s unprecedented and dynamic era of growth, our teams are converting that momentum into tangible results for our customers, large businesses seeking new connections, and our shareholders. At mid-year, we have delivered strong second quarter results that reflect the strength of our increasing customer-driven capital plan and the progress we continue to make across our strategic priorities. While we remain laser focused on delivering improvements in resiliency and reliability for our customers, we know that the most impactful way we can positively affect customer affordability is to help facilitate regional economic growth and connect more new customers onto our system. We remain confident in our ability to deliver these positive customer impacts, strong financial results and long-term value,” said Jason Wells, Chair of the Board, President and CEO of CenterPoint.

“Houston Electric’s growth trajectory continues to underscore our unique position to help facilitate the region’s continued economic growth. As part of the ERCOT process, we now have approximately 14 gigawatts of eligible base or studied load projected by 2031, which would be over a 65% increase from our current system peak demand. CenterPoint’s ability to leverage existing system capacity, track record of executing large load connections, and ability to make targeted investments to unlock additional expansion is allowing us to move at the speed of business and deliver benefits for all customers. Over the next decade, these new connections are forecasted to meaningfully reduce Houston Electric’s residential and commercial delivery charges by at least $5 billion. With the $1.2 billion increase to our capita

CenterPoint Energy reports strong Q1 2026 results; reiterates full-year 2026 guidance; provides an update on Houston Electric load growth

·Reports Q1 2026 earnings of $0.48 per diluted share on a GAAP basis and $0.56 per diluted share on a non-GAAP basis (“non-GAAP EPS”)

·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 2025 delivered results1

·Announces 12.2 gigawatts of firmly committed industrial load at Houston Electric, expecting 8 gigawatts of data center load to be energized by 2029

Houston – April 23, 2026 – CenterPoint Energy, Inc.

(NYSE: CNP), or “CenterPoint,” today reported net income of $316 million, or $0.48 per diluted share, on a GAAP basis for the first quarter of 2026, compared to $0.45 per diluted share in the comparable period of 2025.

Non-GAAP EPS for the first quarter of 2026 was $0.56, compared to $0.53

per diluted share in the comparable period of 2025. These strong first-quarter results were primarily driven by growth and regulatory recovery, which contributed $0.11 per share of favorability compared to the first quarter of 2025. This favorability was partially offset by $0.02 per share of unfavorable weather and usage and $0.04 of unfavorability from increased interest expense. Additionally, $0.03 of unfavorable variance was primarily related to the divestiture of Louisiana and Mississippi natural gas LDC businesses, reflecting the completed sale in the first quarter of 2025.

CenterPoint announced more than 12 gigawatts of firmly committed industrial load and increased its data center load forecast, now expecting to energize 8 gigawatts of projects in the Greater Houston area by 2029, with 3.5 gigawatts already under construction.

“We are fortunate to be living in one of the most unique and exciting times in our industry’s history. Our teams are moving at pace to execute our customer-focused capital plans, deliver strong financial results, and facilitate real and tangible electric load growth for the benefit of all our customers. Our strong first quarter performance positions us well for the remainder of the year and delivering results at or above the midpoint of our 2026 earnings guidance range. We remain confident that we are making the right investments to produce safer, more reliable, and more resilient outcomes than ever before.” said Jason Wells, chair of the Board, president and CEO of CenterPoint.

“We understand the best way to deliver on affordability for our current customers is by bringing more connections onto our electric systems. With the incremental and accelerating growth we see in Greater Houston alone, we project to be able to deliver customer savings of approximately $4 billion over the next decade. Through our team’s disciplined execution and moving at the speed of business, we have made meaningful progress for numerous new customers to help them realize their large load connections. As a result, we now have clear line of sight to 12.2 gigawatts of firmly committed industrial load. Given all these trends, we continue to believe we have one of the most tangible and executable growth plans in the industry.” concluded Wells.

Earnings Outlook

In addition to presenting its financial results in accordance with GAAP, including presentation of net income or income available to common shareholders (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
