Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Assets and liabilities that are recorded at fair value in the Registrants’ Condensed Consolidated Balance Sheets are categorized based upon the level of judgment associated with the inputs used to measure their value. Hierarchical levels, as defined below and directly related to the amount of subjectivity associated with the inputs to fair valuations of these assets and liabilities, are as follows:

Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. The types of assets carried at Level 1 fair value generally are exchange-traded derivatives and equity securities.

Level 2: Inputs, other than quoted prices included in Level 1, are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar instruments in active markets and inputs other than quoted prices that are observable for the asset or liability. Fair value assets and liabilities that are generally included in this category are derivatives with fair values based on inputs from actively quoted markets. A market approach is utilized to value the Registrants’ Level 2 interest rate derivative assets or liabilities and natural gas derivative assets or liabilities. CenterPoint Energy’s Level 2 indexed debt securities derivative is valued using an option model and a discounted cash flow model, which uses projected dividends on the ZENS-Related Securities and a discount rate as observable inputs.

Level 3: Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. Unobservable inputs reflect the Registrants’ judgments about the assumptions market participants would use in pricing the asset or liability since limited market data exists. The Registrants develop these inputs based on the best information available, including the Registrants’ own data.

The Registrants determine the appropriate level for each financial asset and liability on a quarterly basis and recognize transfers between levels at the end of the reporting period. As of September 30, 2025 and December 31, 2024, the Registrants did not have any assets or liabilities classified as Level 3.

The following tables present information about the Registrants’ assets and liabilities measured at fair value on a recurring basis as of September 30, 2025 and December 31, 2024 and indicate the fair value hierarchy of the valuation techniques utilized by the Registrants to determine such fair value.

The fair values of cash and cash equivalents and investments in equity securities measured at fair value are estimated to be approximately equivalent to carrying amounts and have been excluded from the table below. Additionally, CenterPoint Energy’s ZENS indexed debt securities derivative is stated at fair value and is excluded from the table below. The fair value of each debt instrument included below is determined by multiplying the principal amount of each debt instrument by a

combination of historical trading prices and comparable issue data. These liabilities, which are not measured at fair value in the Registrants’ Condensed Consolidated Balance Sheets, but for which the fair value is disclosed, would be classified as Level 2 in the fair value hierarchy.

Common Stock (CenterPoint Energy)

(a) Equity Distribution Agreement

On January 10, 2024, CenterPoint Energy entered into an Equity Distribution Agreement with certain financial institutions with respect to the offering and sale from time to time of shares of Common Stock, having an aggregate gross sales price of up to $500 million. Sales of Common Stock may be made by any method permitted by applicable law and deemed to be an “at the market offering” as defined in Rule 415 of the Securities Act. The offer and sale of Common Stock under the Equity Distribution Agreement will terminate upon the earliest of (1) the sale of all Common Stock subject to the Equity Distribution Agreement, (2) termination of the Equity Distribution Agreement, or (3) May 17, 2026.

In April 2025, CenterPoint Energy entered into separate forward sale agreements pursuant to the Equity Distribution Agreement with certain of the ATM Forward Purchasers relating to 3,277,764 shares and 680,902 shares of Common Stock at an initial forward price of $36.29 per share and $36.72 per share, respectively. The gross sales price of these shares totaled approximately $120 million and $25 million, respectively. In connection with these sales, the ATM Forward Sellers were deemed to have received commissions of approximately $1 million and less than $1 million, respectively. In May 2025, CenterPoint Energy entered into a forward sale agreement with an ATM Forward Purchaser relating to 521,962 shares of Common Stock at an initial forward price of $37.49 per share. The gross sales price of these shares totaled approximately $20 million. In connection with these sales, the ATM Forward Seller was deemed to have received a commission of less than $1 million. CenterPoint Energy has not received any proceeds from such sales of borrowed shares. On a settlement date or dates, if CenterPoint Energy elects to physically settle the forward sale agreements, CenterPoint Energy will issue shares of Common Stock to the counterparties at the then-applicable forward sale price. The forward price used to determine amounts due at settlement is calculated based on a floating interest rate factor equal to the overnight bank funding rate less a spread of 75 basis points, and will be subject to decrease on certain dates specified in the forward sale agreements by specified amounts related to expected dividends on the shares of the Common Stock during the term of the forward sale agreements. If the overnight bank funding rate is less than or more than the spread on any day, the interest rate factor will result in a reduction or an increase, respectively, of the forward sale price.As initial pricing terms were based on market prices for Common Stock, no amounts were recorded at the execution of the forward sale agreements. CenterPoint Energy will receive proceeds when settlement occurs and will record the proceeds in equity.

The forward sale agreements require CenterPoint Energy to, at its election on or prior to May 14, 2026, either (1) physically settle the transactions by issuing the total of 4,480,628 shares of Common Stock to the counterparties in exchange for cash of approximately $164 million or (2) net settle the transactions in whole or in part through the delivery or receipt of cash or shares of Common Stock. Pursuant to such net settlement provisions, these agreements could have been settled on September 30, 2025 by CenterPoint Energy’s delivery of approximately $9.5 million of cash or 245,645 shares of Common Stock to the banking counterparties if CenterPoint Energy unilaterally elected net cash or net share settlement, respectively. As of September 30, 2025, CenterPoint Energy had approximately $85 million of remaining capacity available under the at-the-market program.

(b) Forward Sale Agreements

In May 2025, CenterPoint Energy entered into separate forward sale agreements with certain financial institutions relating to an aggregate of 24,864,865 shares of Common Stock at an initial forward price of $36.26 per share. On a settlement date or dates, if CenterPoint Energy elects to physically settle the forward sale agreements, CenterPoint Energy will issue shares of Common Stock to the counterparties at the then-applicable forward sale price. Each forward sale agreement provides that the initial forward sale price will be subject to adjustment based on a floating interest rate factor equal to the overnight bank funding rate less a spread of 75 basis points, and will be subject to decrease on each of certain dates specified in the relevant forward sale agreement by amounts related to expected dividends on shares of the Common Stock during the term of such forward sale agreement. If the overnight bank funding rate is less than or more than the spread on any day, the interest rate factor will result in a reduction or an increase, respectively of the forward sale price. As initial pricing terms were based on market prices for Common Stock, no amounts were recorded at the execution of the forward sale agreements. CenterPoint Energy will receive proceeds when settlement occurs and will record the proceeds in equity.

The forward sale agreements require CenterPoint Energy to, at its election on or prior to February 25, 2027, either (1) physically settle the transactions by issuing the total of 24,864,865 shares of Common Stock to the counterparties in exchange for cash of $907 million or (2) net settle the transactions in whole or in part through the delivery or receipt of cash or shares of Common Stock. Pursuant to such net settlement provisions, these agreements could also have been settled on September 30, 2025 by CenterPoint Energy’s delivery of approximately $58 million of cash or 1,487,454 shares of Common Stock to the banking counterparties if CenterPoint Energy unilaterally elected net cash or net share settlement, respectively.

Earnings Per Share (CenterPoint Energy)

Earnings Per Share [Abstract]

Earnings Per Share (CenterPoint Energy)

The methodology for calculating basic and diluted earnings per share was disclosed in our combined 2024 Form 10-K. Except as described below, there have been no material changes in those disclosures.

Until settlement of the equity forwards executed in April 2025 and May 2025 further described in Note 15, dilutive earnings per common share reflects the dilutive impact of potential issuances of shares of Common Stock associated with the outstanding equity forwards. The dilutive effect of equity forwards is determined under the treasury stock method. Share dilution occurs when the average market price of Common Stock is higher than the forward sales price at the end of the reporting period.

Diluted earnings per common share will also reflect the dilutive effect of potential conversions of our convertible notes into shares of Common Stock. Convertible debt in which the principal amount must be settled in cash is excluded from the calculation of diluted earnings per common share. There would be no interest expense adjustment to the numerator for the cash-settled portion of the convertible notes because that portion will always be settled in cash. The conversion spread value in shares will be included in diluted earnings per common share using the if-converted method if the average market price of Common Stock is higher than the conversion price. The denominator of diluted earnings per common share is determined by dividing the conversion spread value of the share-settled portion of the convertible notes as of the reporting date by the average share price over the reporting period. For further details about the 2028 Convertible Notes, see Note 9.

The following table reconciles numerators and denominators of CenterPoint Energy’s basic and diluted earnings per common share:

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Debt Issuance (CenterPoint Energy) On October 1, 2025, SIGECO closed on the remaining of the offering of $145 million aggregate principal amount of the Series 2025C Bonds. The proceeds of the 2025C Bonds were used for general corporate purposes, including repaying short-term debt, refunding long-term debt at maturity or otherwise, and funding capital expenditures. Tender Offers (CenterPoint Energy and Houston Electric) In September 2025, CenterPoint Energy commenced cash tender offers for up to (i) $300 million aggregate purchase price of certain of CenterPoint Energy’s outstanding senior notes, ranging from 2.65% to 3.70% due 2030 to 2049, and (ii) $200 million aggregate purchase price of certain of Houston Electric’s general mortgage bonds, ranging from 4.25% to 4.50% due 2044 to 2049. In October 2025, CenterPoint Energy accepted for purchase and paid approximately $504 million in connection with the settlement of the tender offers. Upon completion of the tender offers, CenterPoint Energy cancelled approximately $329 million aggregate principal amount of its senior notes and Houston Electric cancelled approximately $234 million aggregate principal amount of its general mortgage bonds pursuant to the terms of the respective indentures governing such securities, which are reflected in Current portion of other long-term debt on the CenterPoint Energy and Houston Electric Consolidated Balance Sheets. CenterPoint Energy expects to recognize a gain on early extinguishment of debt of approximately $25 million, which will be recognized in Interest income and other finance charges on its Statement of Consolidated Income in the fourth quarter of 2025. Houston Electric expects to recognize a gain on early extinguishment of debt of approximately $24 million, which will be deferred and recognized as a reduction within Regulatory assets on its Consolidated Balance Sheet in the fourth quarter of 2025. Junior Subordinated Notes (CenterPoint Energy) In October 2025, CenterPoint Energy issued $700 million aggregate principal amount of 5.950% Fixed-to-Fixed Reset Rate Junior Subordinated Notes, Series D, due 2056 (the “Series D Notes”). Interest on the Series D Notes accrues from October 2, 2025 and is payable semiannually in arrears on April 1 and October 1 of each year, beginning on April 1, 2026, and maturing on April 1, 2056. The Series D Notes bear interest (i) from and including October 2, 2025 to, but excluding, April 1, 2031 at the rate of 5.950% per annum and (ii) from and including April 1, 2031, during each five-year period following April 1, 2031 (each such five-year period, a “Series D Interest Reset Period”), at a rate per annum equal to the Five-Year Treasury Rate (as defined in the Junior Subordinated Notes Indenture) as of two business days prior to the beginning of the applicable Series D Interest Reset Period plus a spread of 2.223%, with such rate per annum to be reset on each five-year anniversary of April 1, 2031; provided that the interest rate during any Series D Interest Reset Period will not reset below 5.950% per annum (which is the same interest rate as in effect from and including the original issue date to, but excluding, April 1, 2031). So long as no event of default (as defined in the prospectus supplement relating to the offering of the Series D Notes) with respect to the Series D Notes has occurred and is continuing, CenterPoint Energy may, at its option, defer interest payments on the Series D Notes, from time to time, for one or more deferral periods of up to 20 consecutive semiannual interest payment periods, except that no such optional deferral period (as defined in the prospectus supplement relating to the offering of the Series D Notes) may extend beyond the final maturity date of the Series D Notes or end on a day other than the day immediately preceding an interest payment date. During any optional deferral period, CenterPoint Energy (and its majority-owned subsidiaries, as applicable) will not (subject to certain exceptions as described in the Junior Subordinated Notes Indenture): (i) declare or pay any dividends or distributions on any of CenterPoint Energy’s capital stock; (ii) redeem, purchase, acquire or make a liquidation payment with respect to any of CenterPoint Energy’s capital stock; (iii) pay any principal, interest (to the extent such interest is deferrable) or premium on, or repay, repurchase or redeem any of CenterPoint Energy’s indebtedness that ranks equally with or junior to the Series D Notes in right of payment (including debt securities of other series, such as the other series of the Junior Subordinated Notes outstanding); or (iv) make any payments with respect to any guarantees by CenterPoint Energy of any indebtedness if such guarantees rank equally with or junior to the Series D Notes in right of payment. The Series D Notes are CenterPoint Energy’s unsecured obligations and rank junior and subordinate in right of payment to the prior payment in full of CenterPoint Energy’s existing and future Senior Indebtedness (as defined in the Junior Subordinated Notes Indenture). Total proceeds for the sale of the Series D Notes, net of issuance costs and transaction expenses and fees, were approximately $691 million, which were used for general corporate purposes, including the repayment of a portion of CenterPoint Energy’s outstanding commercial paper. Proposed Divestiture of Ohio Natural Gas LDC Business (CenterPoint Energy and CERC) On October 20, 2025, CERC Corp. entered into the Ohio Securities Purchase Agreement to sell all of the issued and outstanding equity interests in CEOH to NFGC. The purchase price is $2.62 billion, subject to adjustment as set forth in the Ohio Securities Purchase Agreement. The purchase price is comprised of the following: (i) $1.42 billion in cash payable to CERC Corp. upon closing of the proposed transaction, subject to adjustments as set forth in the Ohio Securities Purchase Agreement, including adjustments based on net working capital, regulatory assets and liabilities and capital expenditures at closing of the proposed transaction; and (ii) a 364-day seller promissory note, in the original principal amount of $1.2 billion, to be issued by NFGC at the closing of the proposed transaction and payable to CERC Corp. as provided by the terms and conditions of the Seller Note Agreement. The completion of the proposed transaction is subject to customary closing conditions, including (i) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended; (ii) completion of a notice filing and review with the PUCO; and (iii) customary conditions regarding the accuracy of the representations and warranties and compliance by the parties with their respective obligations under the Ohio Securities Purchase Agreement. The proposed transaction is not subject to a financing condition, will not close prior to October 1, 2026 without the consent of CERC Corp., and is expected to close in the fourth quarter of 2026, subject to satisfaction of the foregoing conditions. The proposed transaction did not qualify as held for sale as of September 30, 2025.

Income Tax Disclosure [Abstract]

Income Taxes

The Registrants reported the following effective tax rates:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2025		2024		2025		2024
CenterPoint Energy (1)	(2)	%	21	%	14	%	18	%

Houston Electric (2)	18	%	19	%	19	%	19	%
CERC (3)	(222)	%	21	%	11	%	20	%

(1)CenterPoint Energy’s lower effective tax rate for the three months ended September 30, 2025 compared to the three months ended September 30, 2024 was primarily driven by a $74 million net benefit from state apportionment changes, resulting in a remeasurement of state deferred taxes. This benefit is partially offset by the impact of non-deductible goodwill associated with the sale of the Louisiana and Mississippi natural gas LDC businesses. CenterPoint Energy’s lower effective tax rate for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024 was primarily driven by a $74 million net benefit from state apportionment changes, resulting in a remeasurement of state deferred taxes. This benefit is partially offset by the impact of non-deductible goodwill associated with the sale of the Louisiana and Mississippi natural gas LDC businesses and the absence of impacts associated with the state deferred tax remeasurement and valuation allowance related to the Louisiana and Mississippi natural gas LDC businesses recorded in 2024 upon classification as held for sale. For additional detail, see Note 3.

(2)Houston Electric’s lower effective tax rate for the three months ended September 30, 2025 compared to the three months ended September 30, 2024 was primarily driven by a decrease in state income taxes.

(3)CERC’s lower effective tax rate for the three months ended September 30, 2025 compared to the three months ended September 30, 2024 was primarily driven by a $73 million net benefit from state apportionment changes, resulting in a remeasurement of state deferred taxes. This benefit is partially offset by the impact of non-deductible goodwill associated with the sale of the Louisiana and Mississippi natural gas LDC businesses. CERC’s lower effective tax rate for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024 was primarily driven by a $73 million net benefit from state apportionment changes, resulting in a remeasurement of state deferred taxes. This benefit is partially offset by the impact of non-deductible goodwill associated with the sale of the Louisiana and Mississippi natural gas LDC businesses and the absence of impacts associated with the state deferred tax remeasurement and valuation allowance related to the Louisiana and Mississippi natural gas LDC businesses recorded in 2024 upon classification as held for sale. For additional detail, see Note 3.

CenterPoint Energy reported a net uncertain tax liability, inclusive of interest and penalties, of $30 million as of September 30, 2025. The Registrants believe that it is reasonably possible that the Registrants will recognize a $11 million tax benefit, including penalties and interest, in the next 12 months as a result of a lapse of statutes on older exposures, a tax settlement, and/or a resolution of open audits.

Tax Audits and Settlements. Tax years through 2022 have been audited and settled with the IRS for CenterPoint Energy. For tax years 2023, 2024 and 2025, the Registrants are participants in the IRS’s Compliance Assurance Process.

(b) ZENS

In September 1999, CenterPoint Energy issued ZENS having an original principal amount of $1.0 billion, of which $828 million remained outstanding as of September 30, 2025. Each ZENS is exchangeable at the holder’s option at any time for an amount of cash equal to 95% of the market value of the reference shares attributable to such note. The number and identity of the reference shares attributable to each ZENS are adjusted for certain corporate events. CenterPoint Energy’s reference shares for each ZENS consisted of the following:


	September 30, 2025	December 31, 2024
	(in shares)
AT&T Common	0.7185	0.7185
Charter Common	0.061382	0.061382
WBD Common	0.173817	0.173817

CenterPoint Energy pays interest on the ZENS at an annual rate of 2% plus the amount of any quarterly cash dividends paid in respect of the reference shares attributable to the ZENS. The principal amount of the ZENS is subject to increases or decreases to the extent that the annual yield from interest and cash dividends on the reference shares attributable to the ZENS is less than or more than 2.309%. The adjusted principal amount is defined in the ZENS instrument as “contingent principal.” As of September 30, 2025, the ZENS, having an original principal amount of $828 million and a contingent principal amount of $2 million, were outstanding and were exchangeable, at the option of the holders, for cash equal to 95% of the market value of the reference shares attributable to the ZENS.

Segment Reporting [Abstract]

Reportable Segments

The Registrants’ determination of reportable segments considers the strategic operating units under which the CODM manages sales, allocates resources and assesses performance of various products and services to wholesale or retail customers in differing regulatory environments.

As of September 30, 2025, reportable segments by Registrant and information about each Registrant’s CODM were as follows:

CenterPoint Energy

•CenterPoint Energy’s Electric reportable segment consists of electric transmission and distribution services in the Texas Gulf Coast area in the ERCOT region and electric transmission and distribution services primarily to southwestern Indiana and includes power generation and wholesale power operations in the MISO region.

•CenterPoint Energy’s Natural Gas reportable segment consists of (i) intrastate natural gas sales to, and natural gas transportation and distribution for residential, commercial, and industrial customers in Indiana, Minnesota, Ohio and

Texas; and (ii) permanent pipeline connections through interconnects with various interstate and intrastate pipeline companies through CEIP. On October 20, 2025, CenterPoint Energy, through CERC Corp., entered into the Ohio Securities Purchase Agreement to sell all of the issued and outstanding equity interests in CEOH. The proposed transaction is expected to close in the fourth quarter of 2026. For further information, see Note 16 to the Interim Condensed Financial Statements.

•CenterPoint Energy’s Corporate and Other category consists of corporate support operations that support all of CenterPoint Energy’s business operations. CenterPoint Energy’s Corporate and Other also includes office buildings and other real estate used for business operations.

CenterPoint Energy’s CODM, the President and Chief Executive Officer, evaluates performance for all of its reportable segments based on segment net income. The CODM uses segment net income to allocate resources as part of the budgeting and forecasting process as well as during periodic budget-to-actual reviews.

Houston Electric

•Houston Electric’s single reportable segment consists of electric transmission services to transmission service customers in the ERCOT region and distribution services to REPs serving the Texas Gulf Coast area that includes the city of Houston.

Houston Electric’s CODM, the President and Chief Executive Officer, evaluates performance for its single reportable segment based on segment net income. The CODM uses segment net income to allocate resources as part of the budgeting and forecasting process as well as during periodic budget-to-actual reviews.

CERC

•CERC’s single reportable segment following the Restructuring and the closing of the sale of the Louisiana and Mississippi natural gas LDC businesses on March 31, 2025 consists of (i) intrastate natural gas sales to, and natural gas transportation and distribution for, residential, commercial, and industrial customers in Indiana, Minnesota, Ohio and Texas; and (ii) permanent pipeline connections through interconnects with various interstate and intrastate pipeline companies through CEIP. On October 20, 2025, CenterPoint Energy, through CERC Corp., entered into the Ohio Securities Purchase Agreement to sell all of the issued and outstanding equity interests in CEOH.

Debt Disclosure [Abstract]

Short-term Borrowings and Long-term Debt

Debt Issuances. On January 31, 2025, CenterPoint Energy, through its wholly-owned subsidiary SIGECO, issued $165 million aggregate principal amount of 5.69% First Mortgage Bonds, Series 2025A, Tranche A due 2055. Total proceeds, net of transaction expenses and fees, were approximately $164 million, which was used for the acquisition of Posey Solar. See Note 3 for additional detail.

In February 2025, Houston Electric issued $500 million aggregate principal amount of 4.80% General Mortgage Bonds, Series AP, due 2030. Total proceeds, net of transaction expenses and fees, were approximately $495 million, which was used for general limited liability company purposes, including capital expenditures and working capital purposes.

On July 1, 2025, CenterPoint Energy, through its wholly-owned subsidiary SIGECO, entered into a bond purchase agreement with certain institutional investors, under which SIGECO agreed to sell, and each investor agreed to severally purchase (i) on July 1, 2025, $100 million aggregate principal amount of SIGECO’s 5.09% First Mortgage Bonds, Series 2025B, Tranche A due 2031 (the “Series 2025B Tranche A Bonds”) and $105 million aggregate principal amount of SIGECO’s 5.52% First Mortgage Bonds, Series 2025B, Tranche B due 2035 (the “Series 2025B Tranche B Bonds” and, together with the Series 2025B Tranche A Bonds, the “Series 2025B Bonds”), and (ii) on October 1, 2025 or such sooner date, as may be selected by SIGECO upon not less than five business days’ advance notice, $45 million aggregate principal amount of SIGECO’s 5.77% First Mortgage Bonds, Series 2025C, Tranche A due 2040 (the “Series 2025C Tranche A Bonds”) and $100 million aggregate principal amount of SIGECO’s 6.18% First Mortgage Bonds, Series 2025C, Tranche B due 2055 (the “Series 2025C Tranche B Bonds”, and together with the Series 2025C Tranche A Bonds, the “Series 2025C Bonds”) in the series and tranche as set forth in the bond purchase agreement.

On July 1, 2025, SIGECO closed on the offering of $205 million aggregate principal amount of the Series 2025B Bonds. The proceeds of the Series 2025B Bonds were used for general corporate purposes, including repaying short-term debt, refunding long-term debt at maturity or otherwise, and funding capital expenditures. The closing of the Series 2025C Bonds occurred on October 1, 2025. See Note 16 for further information.

In August 2025, Houston Electric issued $600 million aggregate principal amount of 4.95% General Mortgage Bonds, Series AQ, due 2035. Total proceeds, net of transaction expenses and fees, were approximately $592 million, which were used for general limited liability company purposes, including capital expenditures and working capital purposes.

In September 2025, Restoration Bond Company II issued approximately $401.5 million aggregate principal amount of its Series 2025-A Senior Secured System Restoration Bonds in two tranches with interest rates of 4.255% and 4.826% and final maturity dates of December 2035 and June 2040, respectively. Restoration Bond Company II used the net proceeds from the issuance to purchase the system restoration property from Houston Electric. No gain or loss was recognized. The Series 2025-A Senior Secured System Restoration Bonds are secured by the system restoration property, which includes the right to recover, through non-bypassable system restoration charges payable by Houston Electric’s retail electric customers, the qualified costs of Houston Electric authorized by the PUCT Financing Order. Restoration Bond Company II, not Houston Electric, is the owner of the system restoration property, and the assets of Restoration Bond Company II are not available to pay the creditors of Houston Electric or its affiliates, other than Restoration Bond Company II. Houston Electric has no payment obligations with respect to the Series 2025-A Senior Secured System Restoration Bonds except to remit collections of system restoration charges as set forth in a servicing agreement between Houston Electric and Restoration Bond Company II. The non-bypassable system restoration charges are subject to a true-up mechanism.

Convertible Senior Notes. On July 31, 2025, CenterPoint Energy issued $1 billion aggregate principal amount of 3.00% Convertible Senior Notes due 2028. Total proceeds, net of transaction expenses and fees, were approximately $987 million, which was used for general corporate purposes, including repayment of a portion of CenterPoint Energy’s outstanding commercial paper and other debt.

Interest on the 2028 Convertible Notes is payable semiannually in arrears on February 1 and August 1 of each year, beginning on February 1, 2026. The 2028 Convertible Notes will mature on August 1, 2028, unless earlier converted or repurchased by CenterPoint Energy in accordance with their terms.

Prior to the close of business on the business day immediately preceding May 1, 2028, the 2028 Convertible Notes are convertible only under certain conditions. On or after May 1, 2028 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the 2028 Convertible Notes may convert all or any portion of their 2028 Convertible Notes at any time at the conversion rate then in effect, irrespective of the conditions. CenterPoint Energy may not redeem the 2028 Convertible Notes prior to the maturity date.

Upon conversion of the 2028 Convertible Notes, CenterPoint Energy will pay cash up to the aggregate principal amount of the 2028 Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of Common Stock, or a combination of cash and shares of Common Stock, at CenterPoint Energy’s election, in respect of the remainder, if any, of CenterPoint Energy’s conversion obligation in excess of the aggregate principal amount of the 2028 Convertible Notes being converted. The conversion rate for the 2028 Convertible Notes is initially 21.4477 shares of Common Stock per $1,000 principal amount of 2028 Convertible Notes (equivalent to an initial conversion price of approximately $46.63 per share of Common Stock). The initial conversion price of the 2028 Convertible Notes represents a premium of approximately 25.0% over the last reported sale price of the Common Stock on the NYSE on July 28, 2025. Initially, a maximum of 26,809,600 shares of Common Stock may be issued upon conversion of the 2028 Convertible Notes based on the initial maximum conversion rate of 26.8096 shares of Common Stock per $1,000 principal amount of 2028 Convertible Notes. The conversion rate will be subject to adjustment in some events (as described in the 2028 Convertible Notes Indenture) but will not be adjusted for any accrued and unpaid interest.

In addition, following certain corporate events that occur prior to the maturity date of the 2028 Convertible Notes, CenterPoint Energy will, in certain circumstances, increase the conversion rate for a holder of 2028 Convertible Notes who elects to convert its 2028 Convertible Notes in connection with such a corporate event. If CenterPoint Energy undergoes a fundamental change (as defined in the 2028 Convertible Notes Indenture) (other than an exempted fundamental change, as described in the 2028 Convertible Notes Indenture), holders of the 2028 Convertible Notes may require CenterPoint Energy to repurchase for cash all or any portion of their 2028 Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 2028 Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The 2028 Convertible Notes are senior unsecured obligations of CenterPoint Energy and rank senior in right of payment to any of CenterPoint Energy’s indebtedness that is expressly subordinated in right of payment to the 2028 Convertible Notes; equal in right of payment to any of CenterPoint Energy’s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of CenterPoint Energy’s secured indebtedness it may incur in the future to the extent of the value of the assets securing such future secured indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables but excluding intercompany obligations and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with generally accepted accounting principles) of CenterPoint Energy’s subsidiaries.

Debt Repurchases. In March 2025, CERC, through its wholly-owned subsidiary Indiana Gas, repurchased $10 million aggregate principal amount of Indiana Gas’s 6.36% Medium Term Notes, Series F, due 2028 at a redemption price equal to 104.8% of the principal amount of the notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

In April 2025, CenterPoint Energy commenced cash tender offers for up to (i) $600 million aggregate purchase price of certain of CenterPoint Energy’s outstanding senior notes, ranging from 2.65% to 5.40% due 2026 to 2031, and (ii) $400 million aggregate purchase price of certain of CERC’s senior notes, ranging from 4.10% to 5.40% due 2028 to 2047. In May 2025, CenterPoint Energy accepted for purchase and paid approximately $1 billion aggregate purchase price of CenterPoint Energy’s and CERC’s notes pursuant to the tender offers. Upon completion of the tender offers, CenterPoint Energy cancelled approximately $634 million aggregate principal amount of its senior notes and CERC Corp. cancelled approximately $415 million aggregate principal amount of its senior notes pursuant to the terms of the respective indentures governing such notes. CenterPoint Energy and CERC recognized a gain on early extinguishment of debt of approximately $36 million and $9 million, respectively, for the nine months ended September 30, 2025, which is included in Interest expense and other finance charges on their Statements of Consolidated Income.

In June 2025, CERC, through its wholly-owned subsidiary Indiana Gas, repaid at maturity $10 million aggregate principal amount of Indiana Gas’s 6.53% Medium Term Notes, Series E due 2025 at a redemption price equal to 100% of the principal amount to be redeemed plus accrued and unpaid interest thereon.

In July 2025, CenterPoint Energy, through its wholly-owned subsidiary SIGECO, repaid at maturity $41 million aggregate principal amount of SIGECO’s outstanding 3.45% first mortgage bonds due 2025 at a redemption price equal to 100% of the principal amount of the first mortgage bonds to be redeemed plus accrued and unpaid interest thereon.

Credit Facilities. On January 29, 2025, CenterPoint Energy, Houston Electric, CERC and SIGECO each entered into extension agreements to, among other things, extend the maturity date of the lenders’ commitments under each of their respective credit agreements by one year, from December 6, 2027 to December 6, 2028.

Liens. As of September 30, 2025, Houston Electric’s assets were subject to liens securing approximately $9.6 billion of general mortgage bonds outstanding under the General Mortgage, including approximately $68 million held in trust to secure pollution control bonds that mature in 2028 for which CenterPoint Energy is obligated. The general mortgage bonds that are held in trust to secure pollution control bonds are not reflected in Houston Electric’s consolidated financial statements because of the contingent nature of the obligations. Houston Electric may issue additional general mortgage bonds on the basis of retired bonds, 70% of property additions or cash deposited with the trustee. As of September 30, 2025, approximately $4.3 billion of additional general mortgage bonds could be issued on the basis of retired bonds and 70% of property additions. No first mortgage bonds are outstanding under the M&DOT, and Houston Electric is contractually obligated to not issue any additional first mortgage bonds under the M&DOT and is undertaking actions to release the lien of the M&DOT and terminate the M&DOT.

As of September 30, 2025, SIGECO had approximately $1.3 billion aggregate principal amount of first mortgage bonds outstanding. Generally, all of SIGECO’s real and tangible property is subject to the lien of SIGECO’s mortgage indenture which was amended and restated effective as of January 1, 2023. As of September 30, 2025, SIGECO was permitted to issue additional bonds under its mortgage indenture up to 70% of then currently unfunded property additions and approximately $944 million of additional first mortgage bonds could be issued on this basis.

Background and Basis of Presentation	9 Months Ended
Background and Basis of Presentation	Sep. 30, 2025
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background and Basis of Presentation	Background and Basis of Presentation General. This combined Form 10-Q is filed separately by three registrants: CenterPoint Energy, Inc., CenterPoint Energy Houston Electric, LLC and CenterPoint Energy Resources Corp. Information contained herein relating to any individual registrant is filed by such registrant solely on its own behalf. Each registrant makes no representation as to information relating exclusively to the other Registrants or the subsidiaries of CenterPoint Energy, Inc. other than itself or its subsidiaries. Except as discussed in Note 9, no registrant has an obligation in respect of any other Registrant’s debt securities, and holders of such debt securities should not consider the financial resources or results of operations of any Registrant other than the obligor in making a decision with respect to such securities. Basis of Presentation. Included in this combined Form 10-Q are the Interim Condensed Financial Statements of the Registrants. The Interim Condensed Financial Statements, which omit certain financial statement disclosures, are unaudited and should be read with the Registrants’ financial statements included in the Registrants’ combined 2024 Form 10-K. The Combined Notes to Interim Condensed Financial Statements apply to all Registrants and specific references to Houston Electric and CERC herein also pertain to CenterPoint Energy, unless otherwise indicated. The Interim Condensed Financial Statements reflect all normal and recurring adjustments that are, in the opinion of management, necessary to present fairly the financial position, results of operations and cash flows for the respective periods. Amounts reported in the Condensed Statements of Consolidated Income are not necessarily indicative of amounts expected for a full-year period due to the effects of, among other things, (a) seasonal fluctuations in demand for energy, (b) changes in energy commodity prices and the impact of tariffs, (c) timing of maintenance and other expenditures and (d) acquisitions and dispositions of businesses, assets and other interests. Background. CenterPoint Energy is a public utility holding company. CenterPoint Energy’s operating subsidiaries own and operate electric transmission, distribution and generation facilities and natural gas distribution systems. As of September 30, 2025, CenterPoint Energy’s operating subsidiaries were as follows: •Houston Electric owns and operates electric transmission and distribution facilities in the Texas Gulf Coast area that includes the city of Houston; •CERC Corp. (i) directly owns and operates natural gas distribution systems in Minnesota and Texas, (ii) indirectly, through Indiana Gas and CEOH, owns and operates natural gas distribution systems in Indiana and Ohio, respectively, and (iii) owns and operates permanent pipeline connections through interconnects with various interstate and intrastate pipeline companies through CEIP; and •SIGECO provides energy delivery services to electric and natural gas customers located in and near Evansville in southwestern Indiana and owns and operates electric generation assets to serve its electric customers and optimizes those assets in the wholesale power market. As of September 30, 2025, CenterPoint Energy’s reportable segments were Electric, Natural Gas, and Corporate and Other. Houston Electric and CERC each consist of a single reportable segment. For a description of CenterPoint Energy’s reportable segments, see Note 13. On March 7, 2025, SIGECO acquired 100% of the equity interests in Posey Solar, which was constructing a 191 MW solar array in Posey County, Indiana, for approximately $357 million. On March 31, 2025, CenterPoint Energy, through its subsidiary CERC Corp., completed the sale of its Louisiana and Mississippi natural gas LDC businesses for approximately $1.2 billion, subject to adjustment as set forth in the LAMS Asset Purchase Agreement, including adjustments based on net working capital, regulatory assets and liabilities and capital expenditures at closing. For additional information related to both transactions, see Note 3. On October 20, 2025, CenterPoint Energy, through CERC Corp., entered into the Ohio Securities Purchase Agreement to sell all of the issued and outstanding equity interests in CEOH. The proposed transaction is expected to close in the fourth quarter of 2026. For further information, see Note 16 to the Interim Condensed Financial Statements. Principles of Consolidation. The accompanying Interim Condensed Financial Statements have been prepared in conformity with GAAP. The accounts of the Registrants and their wholly-owned and majority-owned and controlled subsidiaries are included in the Interim Condensed Financial Statements. All intercompany transactions and balances are eliminated in consolidation; however, intercompany profits have not been eliminated when such amounts are probable of recovery under the affiliates’ rate regulation process. As of September 30, 2025, CenterPoint Energy, Houston Electric and SIGECO had VIEs including Transition Bond Company IV, Restoration Bond Company II and the SIGECO Securitization Subsidiary, which are consolidated. The consolidated VIEs are wholly-owned, bankruptcy-remote, special purpose entities that were formed solely for the purpose of securitizing transition property or system restoration property or facilitating the securitization financing of qualified costs. CenterPoint Energy, through SIGECO, has a controlling financial interest in the SIGECO Securitization Subsidiary and is its primary beneficiary. Houston Electric has a controlling financial interest in each of the Bond Companies and is the primary beneficiary of each of the Bond Companies. Creditors of CenterPoint Energy, Houston Electric and SIGECO have no recourse to any assets or revenues of the Bond Companies or the SIGECO Securitization Subsidiary, as applicable. The Securitization Bonds issued by these VIEs are payable only from and secured by transition property, system restoration property or securitization property, as applicable, and the bondholders have no recourse to the general credit of CenterPoint Energy, Houston Electric or SIGECO. For further information, see Note 6. The preparation of the Registrants’ financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

As of the closing date, the businesses included approximately 12,000 miles of main pipeline in Louisiana and Mississippi serving approximately 380,000 customers. Prior to the sale, the Louisiana and Mississippi natural gas LDC businesses were reflected in CenterPoint Energy’s Natural Gas reportable segment and CERC’s single reportable segment, as applicable.

The sale was considered an asset sale for tax purposes, requiring net deferred tax liabilities to be excluded from held for sale balances. The deferred taxes associated with the businesses were recognized as a deferred income tax benefit by CenterPoint Energy and CERC upon closing of the sale in 2025.

Although the Louisiana and Mississippi natural gas LDC businesses met the held for sale criteria as of December 31, 2024, their disposals did not represent a strategic shift for CenterPoint Energy or CERC, as both retain significant operations in, and continue to invest in, their natural gas businesses. Therefore, the assets and liabilities, as well as the related income and expenses, associated with these transactions were not reflected as discontinued operations on CenterPoint Energy’s or CERC’s Condensed Consolidated Balance Sheets and Condensed Statements of Consolidated Income, as applicable. Since the depreciation on the Louisiana and Mississippi natural gas LDC businesses’ assets continued to be reflected in revenues through customer rates until the closing of the transaction and was then reflected in the carryover basis of the rate-regulated assets after the sale, CenterPoint Energy and CERC continued to record depreciation on those assets through the closing of the transaction. The Registrants recorded assets and liabilities held for sale at the lower of their carrying value or their estimated fair value less cost to sell.

CenterPoint Energy and CERC recognized a loss of $43 million and a gain of $52 million, respectively, net of transaction costs of $21 million, in connection with the closing of the disposition of the Louisiana and Mississippi natural gas LDC businesses during the nine months ended September 30, 2025. Goodwill of $217 million and $122 million was allocated to the Louisiana and Mississippi natural gas LDC businesses by CenterPoint Energy and CERC, respectively, at the time the held for sale criteria was met and such amount was subsequently derecognized following the completion of the sale on March 31, 2025.

As of September 30, 2025, CenterPoint Energy and CERC had a receivable of $12 million for working capital and other customary adjustments set forth in the LAMS Asset Purchase Agreement.

The assets and liabilities of the Louisiana and Mississippi natural gas LDC businesses classified as held for sale in CenterPoint Energy’s and CERC’s Condensed Consolidated Balance Sheets, as applicable, as of December 31, 2024 included the following:

Effective on the date of the closing of the disposition of the Louisiana and Mississippi natural gas LDC businesses, CERC entered into the Transition Services Agreement, whereby CERC agreed to provide certain transition services, including accounting, customer operations, procurement, and technology functions, for a term of up to 24 months. Subject to the conditions in the Transition Services Agreement, the LAMS Buyers may terminate these support services with 60 days prior written notice. CenterPoint Energy’s and CERC’s charges to the LAMS Buyers for reimbursement of transition services and one-time setup costs were $8.8 million and $24.8 million during the three and nine months ended September 30, 2025, respectively. CenterPoint Energy’s and CERC’s Condensed Consolidated Balance Sheets included a receivable due from the LAMS Buyers for transition services in the amount of $6.6 million as of September 30, 2025.

Acquisition of Posey Solar. On March 7, 2025, SIGECO acquired 100% of the equity interests in Posey Solar, which was constructing a 191 MW solar array in Posey County, Indiana, for approximately $357 million. The purchase represents an asset acquisition. The lease obligations related to Posey Solar were approximately $35 million at the time of acquisition. The purchase was subject to terms and conditions in an order approved by the IURC on September 6, 2023, allowing Indiana Electric to recover project costs, net of PTCs, in rate base rather than a levelized rate, through base rates or the CECA mechanism, depending on which provides more timely recovery. Posey Solar was placed into service on May 30, 2025. Indiana Electric began recovering on the asset through updated base rates on June 17, 2025. On February 3, 2025, the IURC approved Indiana Electric’s request to convey PTCs to customers through the new tax adjustment rider.

Proposed Divestiture of Ohio Natural Gas LDC Business. On October 20, 2025, CenterPoint Energy, through CERC Corp., entered into the Ohio Securities Purchase Agreement to sell all of the issued and outstanding equity interests in CEOH. The proposed transaction is expected to close in the fourth quarter of 2026. For further information, see Note 16 to the Interim Condensed Financial Statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation. Included in this combined Form 10-Q are the Interim Condensed Financial Statements of the Registrants. The Interim Condensed Financial Statements, which omit certain financial statement disclosures, are unaudited and should be read with the Registrants’ financial statements included in the Registrants’ combined 2024 Form 10-K. The Combined Notes to Interim Condensed Financial Statements apply to all Registrants and specific references to Houston Electric and CERC herein also pertain to CenterPoint Energy, unless otherwise indicated. The Interim Condensed Financial Statements reflect all normal and recurring adjustments that are, in the opinion of management, necessary to present fairly the financial position, results of operations and cash flows for the respective periods. Amounts reported in the Condensed Statements of Consolidated Income are not necessarily indicative of amounts expected for a full-year period due to the effects of, among other things, (a) seasonal fluctuations in demand for energy, (b) changes in energy commodity prices and the impact of tariffs, (c) timing of maintenance and other expenditures and (d) acquisitions and dispositions of businesses, assets and other interests.

Background. CenterPoint Energy is a public utility holding company. CenterPoint Energy’s operating subsidiaries own and operate electric transmission, distribution and generation facilities and natural gas distribution systems.

The preparation of the Registrants’ financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Principles of Consolidation

Principles of Consolidation. The accompanying Interim Condensed Financial Statements have been prepared in conformity with GAAP. The accounts of the Registrants and their wholly-owned and majority-owned and controlled subsidiaries are included in the Interim Condensed Financial Statements. All intercompany transactions and balances are eliminated in consolidation; however, intercompany profits have not been eliminated when such amounts are probable of recovery under the affiliates’ rate regulation process.

As of September 30, 2025, CenterPoint Energy, Houston Electric and SIGECO had VIEs including Transition Bond Company IV, Restoration Bond Company II and the SIGECO Securitization Subsidiary, which are consolidated. The consolidated VIEs are wholly-owned, bankruptcy-remote, special purpose entities that were formed solely for the purpose of securitizing transition property or system restoration property or facilitating the securitization financing of qualified costs. CenterPoint Energy, through SIGECO, has a controlling financial interest in the SIGECO Securitization Subsidiary and is its primary beneficiary. Houston Electric has a controlling financial interest in each of the Bond Companies and is the primary beneficiary of each of the Bond Companies. Creditors of CenterPoint Energy, Houston Electric and SIGECO have no recourse to any assets or revenues of the Bond Companies or the SIGECO Securitization Subsidiary, as applicable. The Securitization Bonds issued by these VIEs are payable only from and secured by transition property, system restoration property or securitization property, as applicable, and the bondholders have no recourse to the general credit of CenterPoint Energy, Houston Electric or SIGECO. For further information, see Note 6.

Goodwill

Goodwill (CenterPoint Energy and CERC)

CenterPoint Energy and CERC perform goodwill impairment tests at least annually and evaluate goodwill when events or changes in circumstances indicate that its carrying value may not be recoverable. Goodwill is evaluated for impairment by performing a qualitative assessment or using a quantitative test. If we choose to perform a qualitative assessment and determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative test is then performed; otherwise, no further testing is required. The quantitative test, if required, is performed by comparing the fair value of each reporting unit with the carrying amount of the reporting unit, including goodwill. The estimated fair value of the reporting unit is primarily determined based on an income approach or a weighted combination of income and market

approaches. When the carrying amount is in excess of the estimated fair value of the reporting unit, the excess amount is recorded as an impairment charge, not to exceed the carrying amount of goodwill. CenterPoint Energy and CERC performed their annual goodwill impairment tests in the third quarter of 2025 and determined that no goodwill impairment charge was required for any reporting unit as a result of those tests.

Recent Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). This ASU enhances the transparency of income tax disclosures related to rate reconciliation and income taxes. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. The Registrants plan to adopt this ASU on December 31, 2025, on a retrospective basis. The adoption of this ASU is not expected to have an impact on our consolidated financial statements; however, it is expected to result in additional footnote disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures (“ASU 2024-03”). This ASU improves disclosure of a public business entity’s expense by requiring disaggregated disclosure of expenses in commonly presented expense captions. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and for interim periods beginning after December 15, 2027. Early adoption is permitted. The Registrants are currently evaluating the impact of this ASU on their respective consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). This ASU modernizes the accounting for software costs to adapt to an incremental and iterative software development method. ASU 2025-06 is effective for annual periods beginning after December 15, 2027, and may be applied using a prospective, modified prospective or retrospective transition approach. The Registrants are currently evaluating the impact of this ASU on their respective consolidated financial statements.

Management believes that all other recently adopted and recently issued accounting standards that are not yet effective will not have a material impact on the Registrants’ financial position, results of operations or cash flows upon adoption.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

(a)Purchase Obligations (CenterPoint Energy and CERC)

Commitments include minimum purchase obligations related to CenterPoint Energy’s and CERC’s Natural Gas reportable segment and CenterPoint Energy’s Electric reportable segment. Contracts with minimum payment obligations have various quantity requirements and durations and are not classified as non-trading derivative assets and liabilities in CenterPoint Energy’s and CERC’s Condensed Consolidated Balance Sheets as of September 30, 2025 and December 31, 2024 because these contracts meet an exception as “normal purchases contracts” or do not meet the definition of a derivative. Natural gas and coal supply commitments also include transportation contracts that do not meet the definition of a derivative.

As of September 30, 2025, CenterPoint Energy and CERC had the following undiscounted minimum purchase obligations:


	CenterPoint Energy						CERC
	Natural Gas Supply		Electric Supply (1)		Other (2)		Natural Gas Supply
	(in millions)
Remainder of 2025	$	207	$	24	$	43	$	206
2026	675		98		107		670
2027	592		130		26		588
2028	547		71		10		543
2029	527		68		3		523
Thereafter	1,832		943		145		1,804
Total	$	4,380	$	1,334	$	334	$	4,334

(1)Related to PPAs with commitments ranging from 20 years to 25 years.

(2)Related primarily to technology hardware and software agreements.

Excluded from the table above are estimates for cash outlays from other PPAs through Indiana Electric that do not have minimum thresholds but require payment when energy is generated by the provider. Costs arising from certain of these commitments are pass-through costs, generally collected dollar-for-dollar from retail customers through regulator-approved cost recovery mechanisms.

(b) AMAs (CenterPoint Energy and CERC)

CenterPoint Energy’s and CERC’s Natural Gas businesses continue to utilize AMAs associated with their utility distribution service in Indiana, Minnesota and Texas. The AMAs have varying terms, the longest of which expires in 2029. Pursuant to the provisions of the agreements, CenterPoint Energy’s and CERC’s Natural Gas businesses either sell natural gas to the asset manager and agree to repurchase an equivalent amount of natural gas throughout the year at the same cost, or simply purchase their full natural gas requirements at each delivery point from the asset manager. Generally, AMAs are contracts between CenterPoint Energy’s and CERC’s Natural Gas businesses and an asset manager that are intended to transfer the working capital obligation and maximize the utilization of the assets. In these agreements, CenterPoint Energy’s and CERC’s Natural Gas businesses agree to release transportation and storage capacity to other parties to manage natural gas storage, supply and delivery arrangements for CenterPoint Energy’s and CERC’s Natural Gas businesses and to use the released capacity for other purposes when it is not needed for CenterPoint Energy’s and CERC’s Natural Gas businesses. CenterPoint Energy’s and CERC’s Natural Gas businesses may receive compensation from the asset manager through payments made over the life of the AMAs. CenterPoint Energy’s and CERC’s Natural Gas businesses have an obligation to purchase their winter storage requirements that have been released to the asset manager under these AMAs. Amounts outstanding under these AMAs as of September 30, 2025 and December 31, 2024 were not material.

CenterPoint Energy recognizes guarantee obligations at fair value. CenterPoint Energy discloses parent company guarantees of a subsidiary’s obligation when that guarantee results in the exposure of a material obligation of the parent company even if the probability of fulfilling such obligation is considered remote.

On May 21, 2023, CenterPoint Energy, through Vectren Energy Services, entered into the Equity Purchase Agreement to

sell Energy Systems Group. The sale closed on June 30, 2023.

In the normal course of business prior to the consummation of the transaction on June 30, 2023, CenterPoint Energy, primarily through Vectren, issued parent company level guarantees supporting Energy Systems Group’s obligations. When Energy Systems Group was wholly-owned by CenterPoint Energy, these guarantees did not represent incremental consolidated obligations, but rather, these guarantees represented guarantees of Energy Systems Group’s obligations to allow it to conduct business without posting other forms of assurance. For those obligations where potential exposure can be estimated, management estimated the maximum exposure under these guarantees to be approximately $444 million as of September 30, 2025 and expects the exposure to decrease pro rata. This exposure primarily relates to energy savings guarantees on federal energy savings performance contracts. Other parent company level guarantees, certain of which do not contain a cap on potential liability, were issued prior to the sale of Energy Systems Group in support of federal operations and maintenance projects for which a maximum exposure cannot be estimated based on the nature of the projects.

Under the terms of the Equity Purchase Agreement, ESG Holdings Group must generally use reasonable best efforts to replace existing CenterPoint Energy guarantees with credit support provided by a party other than CenterPoint Energy as of and after the closing of the transaction. The Equity Purchase Agreement also requires certain protections to be provided for any damages incurred by CenterPoint Energy in relation to these guarantees not released by closing. No additional guarantees were provided by CenterPoint Energy in favor of Energy Systems Group subsequent to the closing of the sale on June 30, 2023.

While there can be no assurance that performance under any of these parent company guarantees will not be required in the future, CenterPoint Energy considers the likelihood of a material amount being incurred to be remote. CenterPoint Energy believes that, from Energy Systems Group’s inception in 1994 to the closing of the sale of Energy Systems Group on June 30, 2023, Energy Systems Group had a history of generally meeting its performance obligations and energy savings guarantees and its installed products operated effectively. CenterPoint Energy recorded no amounts on its Condensed Consolidated Balance Sheets as of September 30, 2025 and December 31, 2024 related to its obligation under the outstanding guarantees.

(d) Legal, Environmental and Other Matters

Legal Matters

Litigation Related to Hurricane Beryl. Various federal, state and local governmental and regulatory agencies and other entities, such as the Texas Governor’s office, the Texas legislature and the PUCT, called for, conducted or are conducting inquiries and investigations into Hurricane Beryl, the efforts made by Houston Electric to prepare for, and respond to, this event, including the electric service outage issues, and the procurement of TEEEF. Moreover, additional governmental and regulatory agencies and other entities may conduct such inquiries and investigations. There are significant uncertainties around these inquiries and investigations and potential results and consequences, including with respect to our recovery of costs incurred as a result of Hurricane Beryl and whether any financial penalties will be assessed or changes to Houston Electric’s system, service territories, operations and/or regulatory treatment will result therefrom. Further, on January 22, 2025, a putative shareholder of CenterPoint Energy, Donel Davidson, filed a derivative petition in Harris County District Court, Texas, alleging breach of fiduciary duty and unjust enrichment on behalf of CenterPoint Energy against certain of its current and former directors and officers citing, in part, the topics of these inquiries and investigations. The action seeks to recover damages and other relief from the defendants on behalf of CenterPoint Energy. The action was removed to the Texas Business Courts, and on June 18, 2025, the parties filed an agreed upon stipulation to stay the case, which was approved by the court on June 24, 2025. Additionally, on February 12, 2025, a second putative shareholder of CenterPoint Energy made a demand on the Board to investigate the same basic allegations raised in the derivative petition filed by Donel Davidson.

CenterPoint Energy, CenterPoint Energy Service Company, LLC and Houston Electric are subject to current and potential future litigation and claims arising out of Hurricane Beryl, which litigation and claims could include allegations of, among other things, personal injury, wrongful death, property damage, various economic losses in connection with loss of power, unlawful business practices, and others. Following Hurricane Beryl, several putative class actions were filed against CenterPoint Energy and/or Houston Electric in the District Courts of Harris County, Texas, on behalf of individuals or entities who claim losses due to power outages lasting at least 48 hours as a result of Hurricane Beryl, such actions consisting of the following proposed classes: (1) all restaurants in Harris County, Galveston County, and Montgomery County; (2) all residential customers; and (3) all health, wellness, medical and beauty facilities in Harris County. These putative classes asserted claims and theories of negligence, gross negligence, nuisance, fraud, and/or violation of Houston Electric’s tariff for retail delivery service, and each seeks damages in excess of $100 million for, among other things, business interruption, property damage and loss, cost of repair, loss of use and market value, lost income, nuisance, extreme mental anguish and/or punitive damages. On July 30, 2025, the plaintiffs in the putative class action on behalf of all residential customers nonsuited without prejudice all claims and causes of action. In addition, the plaintiffs in the other two putative class actions have amended their petitions to remove all class action allegations and to assert only claims of gross negligence and intentional misconduct. One of those lawsuits is brought by

approximately 220 individually named plaintiffs, and the other lawsuit includes approximately 45 individually named plaintiffs. Several individual actions have also been filed in Harris County District Courts asserting claims of negligence, negligence per se, negligent undertaking and/or gross negligence against CenterPoint Energy, CenterPoint Energy Service Company, LLC and/or Houston Electric. Certain plaintiffs in these actions allege personal injury or property damage and seek damages in excess of $1 million. These cases have been or will be transferred to the designated MDL pretrial court. CenterPoint Energy, CenterPoint Energy Service Company, LLC and Houston Electric intend to vigorously defend themselves against the lawsuits. CenterPoint Energy and its subsidiaries have general and excess liability insurance policies that provide coverage for third party bodily injury and property damage claims. Given the nature of some allegations, certain insurers have disputed, and more insurers may dispute, coverage for some types of claims or damages that have been or may in the future be alleged by plaintiffs. For example, CenterPoint Energy has received from two insurers denials of indemnity coverage in the cases arising out of power outages based on the failure to supply exclusion, and those insurers have also reserved their rights with respect to coverage in those actions. CenterPoint Energy and Houston Electric intend to continue to pursue all available insurance coverage for all of these matters. To date, there have not been demands, quantification, disclosure or discovery of damages by any party to any of the above legal matters that are sufficient to enable CenterPoint Energy and its subsidiaries to estimate exposure. Given that, as well as the preliminary nature of the proceedings, the number of parties and complexity of issues involved, and the uncertainties of litigation, CenterPoint Energy and its subsidiaries are unable to predict the outcome or consequences of any of the foregoing matters or to estimate a range of potential losses. For more information regarding Hurricane Beryl, see Note 6.

Litigation Related to the February 2021 Winter Storm Event. Various legal proceedings are still pending against numerous entities with respect to the February 2021 Winter Storm Event, including against CenterPoint Energy, Utility Holding, Houston Electric, and CERC. Like other Texas energy companies and TDUs, CenterPoint Energy and Houston Electric have become involved in certain investigations, litigation and other regulatory and legal proceedings regarding their efforts to restore power during the storm and their compliance with NERC, ERCOT and PUCT rules and directives. Additionally, like other natural gas market participants, CERC has been named in litigation alleging gas market manipulation.

CenterPoint Energy, Utility Holding, and Houston Electric, along with hundreds of other defendants (including ERCOT, power generation companies, other TDUs, natural gas producers, REPs, and other entities) received claims and lawsuits filed by plaintiffs alleging wrongful death, personal injury, property damage and other injuries and damages. As of September 30, 2025, there were approximately 220 pending lawsuits that are consolidated in Texas state court in Harris County, Texas, as part of the MDL proceeding related to the February 2021 Winter Storm Event, and CenterPoint Energy and Houston Electric, along with numerous other entities, have been named as defendants in approximately 155 of those lawsuits. One of the lawsuits in the MDL was a putative class action on behalf of everyone who received electric power via the ERCOT grid and sustained a power outage between February 10, 2021 and February 28, 2021. Additionally, Utility Holding is currently named as a defendant in one lawsuit in which CenterPoint Energy and Houston Electric are also named as defendants.

The judge overseeing the MDL issued an initial case management order and stayed all proceedings and discovery. Per the case management order, the judge entertained dispositive motions in five representative or “bellwether” cases and, in late January 2023, issued rulings on them. The judge ruled that ERCOT has sovereign immunity as a governmental entity and dismissed the suits against it. In a subsequent opinion in an unrelated matter, the Texas Supreme Court held that ERCOT is entitled to sovereign immunity. This ruling will apply to claims against ERCOT in the MDL. The MDL judge also dismissed all claims against the natural gas defendants (which list of natural gas defendants incorrectly included Utility Holding) and the REP defendants and some causes of action against the other defendants. CenterPoint Energy expects that the claims against Utility Holding will ultimately be dismissed in light of the judge’s initial rulings. As to the TDU and generator defendants, the judge dismissed some causes of action but denied the motions to dismiss claims for negligence, gross negligence, and nuisance, which denial the TDU defendants and generator defendants asked the courts of appeals to overturn. On April 2, 2024, a three-judge panel of the Court of Appeals for the Fourteenth District of Texas issued an opinion in the TDU mandamus proceeding, granting in part and denying in part the TDUs’ mandamus request. In its opinion, the panel granted the TDUs’ mandamus request relating to the TDUs’ motion to dismiss the plaintiffs’ claims for (1) negligence, (2) negligent nuisance and (3) strict liability nuisance and ordered those claims be dismissed. The panel denied the TDUs’ mandamus request relating to the TDUs’ motion to dismiss the plaintiffs’ gross negligence and intentional nuisance claims. On May 22, 2024, the TDUs filed a mandamus petition with the Supreme Court of Texas, seeking dismissal of the remaining claims. On June 27, 2025, the Supreme Court of Texas issued its decision and held that plaintiffs’ pleadings are insufficient as to both their intentional nuisance and gross negligence claims. The court dismissed plaintiffs’ intentional nuisance claims with prejudice, but concluded that plaintiffs should be given the opportunity to replead their gross negligence claims only.

In the generator mandamus proceeding that was pending in the Court of Appeals for the First District of Texas, a three-judge panel granted the generators’ mandamus request and ordered dismissal of all claims asserted against the generators’ defendants. The plaintiffs asked the entire First Court of Appeals to rehear the panel’s decision. On November 26, 2024, the First Court of Appeals denied that motion. The plaintiffs filed a petition for writ of mandamus with the Supreme Court of Texas on January 31, 2025, and on June 27, 2025, the Supreme Court of Texas requested briefing on the merits in that proceeding.

The plaintiffs filed their brief on the merits on September 26, 2025, and the generator defendants’ response is currently due on November 17, 2025.

The MDL judge allowed defendants (including Houston Electric) to file several additional motions on preliminary legal issues. These motions included the TDUs’ motion to dismiss under Chapter 150 of the Texas Civil Practice and Remedies Code, which was filed in one of the bellwether cases and argued that all of plaintiffs’ claims should be dismissed because the plaintiffs did not include a sufficient certificate by a qualified engineer with their petition as required by Texas law, as well as a motion to deny class certification in the putative class action. On November 13, 2024, the MDL Court granted the TDUs’ motion to dismiss under Chapter 150, and on December 3, 2024, the plaintiffs filed a notice of appeal of that ruling. Briefing in this appellate proceeding is complete. On January 8, 2025, the MDL Court denied class certification in the putative class action. Following issuance of the order denying class certification, a new lawsuit was filed on behalf of approximately 140 plaintiffs in Harris County District Court against hundreds of defendants, including CenterPoint Energy and Houston Electric, and that case was transferred to the MDL on January 23, 2025. In addition, plaintiffs filed a notice of appeal of the denial of class certification on January 27, 2025, but dismissed that appeal on April 28, 2025. On August 13, 2025, the MDL judge signed orders dismissing all of the plaintiffs’ claims against the TDUs except gross negligence. On September 11, 2025, the MDL judge issued an order with a schedule for the plaintiffs to re-plead their gross negligence claims and for the TDUs to file certain dispositive motions in response. All litigation otherwise remains stayed in the MDL. CenterPoint Energy, Utility Holding, and Houston Electric intend to vigorously defend themselves against the claims raised.

CenterPoint Energy and Houston Electric have also responded to inquiries from the Texas Attorney General and the Galveston County District Attorney’s Office, and various other regulatory and governmental entities also conducted inquiries, investigations and other reviews of the February 2021 Winter Storm Event and the efforts made by various entities to prepare for, and respond to, the event, including the electric generation shortfall issues.

In February 2023, twelve lawsuits were filed in state district court in Harris County and Tom Green County, Texas, against dozens of gas market participants in Texas, including natural gas producers, processors, pipelines, marketers, sellers, traders, gas utilities, and financial institutions. Plaintiffs named CERC as a defendant, along with “CenterPoint Energy Services, Inc.,” incorrectly identifying it as CERC’s parent company (CenterPoint Energy previously divested CenterPoint Energy Services, Inc.). One lawsuit filed in Harris County is a putative class action on behalf of two classes of electric and natural gas customers (those who experienced a loss of electricity and/or natural gas, and those who were charged securitization-related surcharges on a utility bill or were otherwise charged higher rates for electricity and/or gas during the February 2021 Winter Storm Event), potentially including millions of class members. Two other lawsuits (one filed in Harris County and one in Tom Green County) were brought by an entity that purports to be an assignee of the claims of tens of thousands of persons and entities. These, and nine other similar lawsuits filed in Harris County, generally allege that the defendants engaged in gas market manipulation and price gouging, including by intentionally withholding, suppressing, or diverting supplies of natural gas in connection with the February 2021 Winter Storm Event, Winter Storm Elliott, and other severe weather conditions, and through financial market manipulation. Plaintiffs allege that this manipulation impacted gas supply and prices as well as the market, supply, and price of electricity in Texas and caused blackouts and other damage. Plaintiffs assert claims for tortious interference with existing contract, private nuisance, and unjust enrichment, and allege a broad array of injuries and damages, including personal injury, property damage, and harm from certain costs being securitized and passed on to ratepayers. The lawsuits do not specify the amount of damages sought, but seek broad categories of actual, compensatory, statutory, consequential, economic, and punitive damages; restitution and disgorgement; pre- and post-judgment interest; costs and attorneys’ fees; and other relief. All twelve lawsuits have been tagged for transfer to the existing MDL proceeding referenced above, but only three of the cases have been served against the defendants, including CERC. These gas market cases are in addition to the 220 cases noted above regarding electric market issues.

On February 2, 2024, CERC filed pleas to the jurisdiction in the three cases in which it was served; CERC also partially joined the other defendants’ motions to dismiss and additional pleas to the jurisdiction. On April 2, 2024, plaintiffs in the three served cases filed amended petitions rather than responding to pleas to the jurisdiction and motions to dismiss. Among other changes, plaintiffs in these three cases dismissed CenterPoint Energy Services, Inc., but maintained the same three causes of action as to the remaining defendants. CERC has vigorously defended itself against the claims raised, including filing updated pleas to the jurisdiction on May 17, 2024 in response to plaintiffs’ amended petitions and intends to continue to do so. On August 12, 2024, plaintiffs in the putative class action filed a motion for leave to amend to add additional plaintiffs/class representatives. Defendants opposed this motion on September 20, 2024. On September 23, 2024, the MDL judge heard oral argument on CERC’s plea to the jurisdiction and defendants’ motions to dismiss and other pleas to the jurisdiction. On November 7, 2024 and November 11, 2024, the MDL judge granted defendants’ motion to dismiss and CERC’s plea to the jurisdiction in all three cases. As a result of these rulings, all claims against CERC were dismissed with prejudice. Plaintiffs have appealed these rulings, and the appeals have been assigned to the Court of Appeals for the First District of Texas. On December 4, 2024, the MDL judge denied as moot a plaintiff’s motion for leave to amend to add additional plaintiffs/class representatives in the putative class action case. On January 17, 2025, the plaintiffs in the putative class action case filed an

unopposed motion to dismiss their appeal, which the Court of Appeals granted on February 4, 2025. The parties have now completed their briefing.

To date, there have not been demands, quantification, disclosure or discovery of damages by any party to any of the above legal matters that are sufficient to enable CenterPoint Energy and its subsidiaries to estimate exposure. Given that, as well as the preliminary nature of the proceedings, the number of parties and complexity of issues involved, and the uncertainties of litigation, CenterPoint Energy and its subsidiaries are unable to predict the outcome or consequences of any of the foregoing matters or to estimate a range of potential losses. CenterPoint Energy and its subsidiaries have general and excess liability insurance policies that provide coverage for third party bodily injury and property damage claims. As CenterPoint Energy previously noted, given the nature of certain of the plaintiffs’ allegations, insurance coverage may not be available other than for third party bodily injury and property damage claims caused by an accident, and one of CenterPoint Energy’s insurers has reserved its rights with respect to coverage for plaintiffs’ intentional nuisance claims as well as plaintiffs’ claims in the gas market cases. CenterPoint Energy and its subsidiaries intend to continue to pursue all available insurance coverage for all of these matters.

Jefferson Parish. Several parishes and the State of Louisiana filed 42 suits under Louisiana’s State and Local Coastal Resources Management Act against hundreds of oil and gas companies seeking compensatory damages for contamination and erosion of the Louisiana coastline allegedly caused by historical oil and gas operations. One of the defendants in one of the lawsuits (filed in 2013 only by the Parish of Jefferson) is Primary Fuels, Inc., a predecessor company of CenterPoint Energy, which operated in Louisiana from 1983-1989. All 42 suits were removed to Louisiana federal courts twice and were stayed for several years pending the district courts’ consideration of various motions to remand and multiple appeals of remand orders. Several cases involving other parishes were remanded to Louisiana state court. To date, two of the 42 suits have substantially progressed in state court. The first case, Cameron Parish v. Auster Oil & Gas, Inc., et al., settled shortly before trial on confidential terms. The second case, Plaquemines Parish v. Rozel Operating Co., et al., was tried against one defendant, Chevron Corporation, and on April 4, 2025, the jury returned a verdict of $744.6 million. Before final judgment was entered, the Rozel case was stayed until the United States Supreme Court rules on the merits of a jurisdictional issue in a related case that does not include Primary Fuels, Inc. As of September 30, 2025, the federal district court had not ruled on Jefferson Parish’s motion to remand to state court the lawsuit which includes Primary Fuels, Inc. among the defendants. The timing of further progress in the Jefferson Parish case is uncertain and dependent in part on the court’s ruling on the motion to remand and further developments in other related Chevron Corporation cases. 

Because of the procedurally preliminary nature of the proceedings in the case in which Primary Fuels, Inc. is a defendant, lack of information about both the scope of and damages for Jefferson Parish’s claim against Primary Fuels, Inc., the number of parties and complexity of issues involved, and the uncertainties of litigation, CenterPoint Energy and its subsidiaries are unable to predict the outcome or consequences of this matter or to estimate a range of potential losses. CenterPoint Energy intends to continue to vigorously defend itself against the claims raised and pursue any and all available insurance coverage.

Environmental Matters

MGP Sites. CenterPoint Energy, CERC and their predecessors, including predecessors of Vectren, operated MGPs in the past. The costs CenterPoint Energy or CERC, as applicable, expect to incur to fulfill their respective obligations are estimated by management using assumptions based on actual costs incurred, the timing of expected future payments and inflation factors, among others. While CenterPoint Energy and CERC have recorded obligations for all costs which are probable and estimable, including amounts they are presently obligated to incur in connection with activities at these sites, it is possible that future events may require remedial activities which are not presently foreseen, and those costs may not be subject to PRP or insurance recovery.

(i)Minnesota MGPs (CenterPoint Energy and CERC). With respect to certain Minnesota MGP sites, CenterPoint Energy and CERC have completed state-ordered remediation and continue state-ordered monitoring and water treatment. CenterPoint Energy and CERC recorded a liability as reflected in the table below for continued monitoring and any future remediation required by regulators in Minnesota.

(ii)Indiana MGPs (CenterPoint Energy and CERC). In the Indiana Gas service territory, the existence, location and certain general characteristics of 26 gas manufacturing and storage sites have been identified for which CenterPoint Energy and CERC may have some remedial responsibility. A remedial investigation/feasibility study was completed at one of the sites under an agreed upon order between Indiana Gas and the IDEM, and a Record of Decision was issued by the IDEM in January 2000. The remaining sites have been submitted to the IDEM’s VRP. CenterPoint Energy has also identified its involvement in five manufactured gas plant sites in SIGECO’s service territory, all of which are currently enrolled in the IDEM’s VRP. CenterPoint Energy is currently conducting some level of remedial activities, including groundwater monitoring at certain sites.

(iii)Other MGPs (CenterPoint Energy and CERC). In addition to the Minnesota and Indiana sites, the EPA and other regulators have investigated MGP sites that were owned or operated by CenterPoint Energy or CERC or may have been owned by one of their former affiliates.

The cost estimates are based on studies of a site or industry average costs for remediation of sites of similar size. The actual remediation costs will depend on the number of sites to be remediated, the participation of other PRPs, if any, and the remediation methods used.

CenterPoint Energy and CERC do not expect the ultimate outcome of these matters to have a material adverse effect on the financial condition, results of operations or cash flows of either CenterPoint Energy or CERC.

Asbestos. Some facilities owned by the Registrants or their predecessors contain or have contained asbestos insulation and other asbestos-containing materials. The Registrants are from time to time named, along with numerous others, as defendants in lawsuits filed by a number of individuals who claim injury due to exposure to asbestos, and the Registrants anticipate that additional claims may be asserted in the future. Although their ultimate outcome cannot be predicted at this time, the Registrants do not expect these matters, either individually or in the aggregate, to have a material adverse effect on their financial condition, results of operations or cash flows.

CCR Rule (CenterPoint Energy). In April 2015, the EPA finalized its CCR Rule, which regulates ash as non-hazardous material under the RCRA. The final rule allows beneficial reuse of ash, and a portion of the ash generated by Indiana Electric’s generating plants will continue to be reused.

Indiana Electric has three ash ponds, two at the F.B. Culley facility (Culley East and Culley West) and one at the A.B. Brown facility. Under the CCR Rule, Indiana Electric is required to perform integrity assessments, including ground water monitoring, at its F.B. Culley and A.B. Brown generating stations. Pursuant to the CCR Rule, both the Culley East and A.B. Brown facilities were taken out of service in a timely manner per the commitments made to the EPA in the extension requests filed for both ponds. On April 24, 2019, Indiana Electric received an order from the IURC approving recovery in rates of costs associated with the closure of the Culley West pond, which has already completed closure activities. On August 14, 2019, Indiana Electric filed its petition with the IURC for recovery of costs associated with the closure of the A.B. Brown ash pond, which would include costs associated with the excavation and recycling of ponded ash. This petition was subsequently approved by the IURC on May 13, 2020. On October 28, 2020, the IURC approved Indiana Electric’s ECA proceeding, which included the initiation of recovery of the federally mandated project costs.

On November 1, 2022, Indiana Electric filed for a CPCN to recover federally mandated costs associated with closure of the Culley East Pond, its third and final ash pond. Indiana Electric sought accounting and ratemaking relief for the project, and on June 8, 2023, Indiana Electric filed a revised CPCN for recovery of the federally mandated ash pond costs. On February 7, 2024 the IURC approved the federally mandated costs, both incurred and projected, of $52 million in capital costs, plus an estimated $133,000 in annual operation and maintenance expenses, for recovery through the ECA. Following approval of its most recent rate case, this project is now being recovered through base rates.

As of September 30, 2025, CenterPoint Energy had recorded an approximate $137 million ARO, which represents the discounted value of future cash flow estimates to close the ponds at A.B. Brown and F.B. Culley. This estimate is subject to change due to the contractual arrangements; continued assessments of the ash, closure methods, and the timing of closure;

implications of Indiana Electric’s generation transition plan; changing environmental regulations; and proceeds received from the settlements in previously settled insurance proceedings. In addition to these AROs, Indiana Electric also anticipates equipment purchases of between $60 million and $80 million to complete the A.B. Brown closure project.

On April 25, 2024, the EPA released its final Hazardous and Solid Waste Management System; Disposal of Coal Combustion Residuals from Electric Utilities; Legacy CCR Surface Impoundments rule (CCR Legacy Rule), which was published in the Federal Register in May 2024. The CCR Legacy Rule requires companies to investigate previously closed impoundments that were used historically for ash disposal or locations which have had ash placed on them in amounts set forth in the CCR Legacy Rule. The Registrants have completed their preliminary review of potential sites that will require further investigation under the CCR Legacy Rule and identified certain sites in Indiana for further evaluation. During 2024, Indiana Electric recorded an approximate $11 million ARO with a corresponding increase of $11 million to Property, plant and equipment for amounts recoverable for electric generation stations that are currently in service. These estimates reflect the discounted value of future estimated capping costs for an area of historic ash placement at F.B. Culley. Indiana Electric will continue to refine the assumptions, engineering analyses and resulting cost estimates associated with this ARO and such refinement could materially impact the amount of the estimated ARO.

Clean Water Act Permitting of Groundwater and Power Plant Discharges. In April 2020, the U.S. Supreme Court issued an opinion providing that indirect discharges via groundwater or other non-point sources are subject to permitting and liability under the Clean Water Act when they are the functional equivalent of a direct discharge. On November 27, 2023, the EPA published draft guidance regarding the application of the “functional equivalent” analysis as related to permitting of certain discharges through groundwater to surface waters. The Registrants do not currently anticipate impacts from this guidance, but groundwater monitoring continues under the CCR Rule.

In 2015, the EPA finalized revisions to the existing steam electric wastewater discharge standards which set more stringent wastewater discharge limits and effectively prohibited further wet disposal of coal ash in ash ponds. In February 2019, the IURC approved Indiana Electric’s Effluent Limitation Guidelines Compliance Plan for its F.B. Culley Generating Station, which was completed in compliance with the requirements of the Effluent Limitation Guidelines. On April 25, 2024, the EPA released its final Supplemental Effluent Limitation Guidelines and Standards for the Steam Electric Generating Point Source Category. On September 29, 2025, the EPA released a proposed rule to extend various deadlines and other provisions of the 2024 Supplemental Effluent Limitation Guidelines. The Registrants currently anticipate that they will be in compliance with the Supplemental Effluent Limitation Guidelines at the Culley facility due to previous wastewater treatment upgrades.

Other Environmental. From time to time, the Registrants identify the presence of environmental contaminants during operations or on property where their predecessors have conducted operations. Other such sites involving contaminants may be identified in the future. The Registrants have and expect to continue to remediate any identified sites consistent with state and federal legal obligations. From time to time, the Registrants have received notices, and may receive notices in the future, from regulatory authorities or others regarding status as a PRP in connection with sites found to require remediation due to the presence of environmental contaminants. In addition, the Registrants have been, or may be, named from time to time as defendants in litigation related to such sites. Although the ultimate outcome of such matters cannot be predicted at this time, the Registrants do not expect these matters, either individually or in the aggregate, to have a material adverse effect on their financial condition, results of operations or cash flows.

Other Proceedings

The Registrants are involved in other legal, environmental, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. From time to time, the Registrants are also defendants in legal proceedings with respect to claims brought by various plaintiffs against broad groups of participants in the energy industry. Some of these proceedings involve substantial amounts. The Registrants regularly analyze current information and, as necessary, provide accruals for probable and reasonably estimable liabilities on the eventual disposition of these matters. The Registrants do not expect the disposition of these matters to have a material adverse effect on the Registrants’ financial condition, results of operations or cash flows.

Regulated Operations [Abstract]

Regulatory Matters

Equity Return

The Registrants are at times allowed by a regulator to defer an equity return as part of the recoverable carrying costs of a regulatory asset. A deferred equity return is capitalized for rate-making purposes, but it is not included in the Registrant’s regulatory assets on its Condensed Consolidated Balance Sheets. The allowed equity return is recognized in the Condensed Statements of Consolidated Income as it is recovered in rates. The recoverable allowed equity return not yet recognized by the Registrants is as follows:


	September 30, 2025						December 31, 2024
	CenterPoint Energy (1)		Houston Electric (2)		CERC (3)		CenterPoint Energy (1)		Houston Electric (2)		CERC (3)
	(in millions)
Unrecognized equity return	$	313	$	144	$	105	$	251	$	94	$	92

(1)In addition to the amounts described in (2) and (3) below, represents CenterPoint Energy’s allowed equity return on post in-service carrying cost generally associated with investments at SIGECO.

(2)Represents Houston Electric’s allowed equity return on TEEEF costs and certain storm restoration costs.

(3)Represents CERC’s allowed equity return on post in-service carrying cost associated with certain distribution facilities replacement expenditures in Texas and at Indiana Gas.

February 2021 Winter Storm Event

In February 2021, certain of the Registrants’ jurisdictions experienced an extreme and unprecedented winter weather event that resulted in prolonged freezing temperatures, which impacted their businesses. The February 2021 Winter Storm Event impacted wholesale prices of CenterPoint Energy’s and CERC’s natural gas purchases and their ability to serve customers in their Natural Gas service territories, including due to the reduction in available natural gas capacity and impacts to CenterPoint Energy’s and CERC’s natural gas supply portfolio activities, and the effects of weather on their systems and their ability to transport natural gas, among other things. The overall natural gas market, including the markets from which CenterPoint Energy and CERC sourced a significant portion of their natural gas for their operations, experienced significant impacts caused by the February 2021 Winter Storm Event, resulting in extraordinary increases in the cost of natural gas purchased by CenterPoint Energy and CERC of approximately $2 billion. CenterPoint Energy and CERC have completed recovery of natural gas costs in Mississippi, Indiana, Louisiana and Texas, and continue to recover the natural gas cost in Minnesota. As of September 30, 2025, each of CenterPoint Energy and CERC had recorded current regulatory assets of $67 million and non-current regulatory assets of $21 million associated with the February 2021 Winter Storm Event. As of December 31, 2024, each of CenterPoint Energy and CERC had recorded current regulatory assets of $67 million and non-current regulatory assets of $67 million associated with the February 2021 Winter Storm Event.

As of September 30, 2025 and December 31, 2024, as authorized by the PUCT, each of CenterPoint Energy and Houston Electric had recorded a regulatory asset of $7 million and $8 million for bad debt expenses resulting from REPs’ default on their obligation to pay delivery charges to Houston Electric net of collateral. Additionally, each of CenterPoint Energy and Houston Electric had recorded a regulatory asset of $18 million and $19 million as of September 30, 2025 and December 31, 2024, respectively, for reimbursement of costs associated with the February 2021 Winter Storm Event. Each of the aforementioned regulatory assets are being amortized over five years beginning April 28, 2025, which was the date that rates became effective following the PUCT’s final order in the Houston Electric rate case.

See Note 11(d) for further information regarding litigation related to the February 2021 Winter Storm Event.

Texas Public Securitization

The Texas Natural Gas Securitization Finance Corporation issued customer rate relief bonds in March 2023, and on March 23, 2023, CenterPoint Energy and CERC, collectively, received approximately $1.1 billion in cash proceeds from the issuance and sale of the state’s customer rate relief bonds. As CenterPoint Energy and CERC have no future financial obligations for the repayment of the state’s customer rate relief bonds, the customer rate relief bonds are not recorded on CenterPoint Energy’s or CERC’s balance sheets. The $1.1 billion in cash proceeds from the state’s customer rate relief bonds is considered to be a government grant. The state’s customer rate relief bonds are backed in part by customer rate relief property, including customer rate relief charges, which are non-bypassable uniform monthly volumetric charges to be paid by all existing and future sales customers as a component of each regulated utility’s gas cost, separate from their base rate. CERC only acts as a collection agent, whose duties include management, servicing and administration of a portion of the customer rate relief property which is associated with the customer rate relief charge imposed on customers of CERC under the guidance and direction from the Railroad Commission. The Texas Natural Gas Securitization Finance Corporation, and not CenterPoint Energy or CERC, is the owner of the customer rate relief property. The assets of the Texas Natural Gas Securitization Finance Corporation are not available to pay creditors of CenterPoint Energy, CERC, or their affiliates. While the customer rate relief charges will be included by CERC in their monthly billings, the billing amount is established by the Railroad Commission. CERC will remit all customer rate relief charges collected to the financing entity set up by the Railroad Commission. Therefore, the collection and servicing of customer rate relief charges have no impact on the respective Condensed Statements of Consolidated Income of CenterPoint Energy or CERC.

Indiana Electric Securitization of Generation Retirements (CenterPoint Energy)

On January 4, 2023, the IURC issued an order in accordance with Indiana Senate Enrolled Act 386 authorizing the issuance of up to $350 million in securitization bonds to securitize qualified costs associated with the retirements of Indiana Electric’s A.B. Brown coal-fired generation facilities. The SIGECO Securitization Subsidiary issued $341 million aggregate principal amount of the SIGECO Securitization Bonds on June 29, 2023 and used a portion of the net proceeds from the issuance of the SIGECO Securitization Bonds to purchase the securitization property from SIGECO. No gain or loss was recognized.

The SIGECO Securitization Bonds are secured by the securitization property, which includes the right to recover, through non-bypassable securitization charges payable by SIGECO’s retail electric customers, the qualified costs of SIGECO authorized by the IURC order. The SIGECO Securitization Subsidiary, and not SIGECO, is the owner of the securitization property, and the assets of the SIGECO Securitization Subsidiary are not available to pay the creditors of SIGECO or its affiliates, other than

the SIGECO Securitization Subsidiary. SIGECO has no payment obligations with respect to the SIGECO Securitization Bonds except to remit collections of securitization charges as set forth in a servicing agreement between SIGECO and the SIGECO Securitization Subsidiary. The non-bypassable securitization charges are subject to a true-up mechanism.

Houston Electric TEEEF

Pursuant to legislation passed in 2021, Houston Electric entered into two leases for TEEEF (temporary generation). Houston Electric defers costs associated with the short-term and long-term leases that are probable of recovery and would otherwise be charged to expense in a regulatory asset, including allowed debt returns, and determined that such regulatory assets remain probable of recovery as of September 30, 2025. Expenses associated with the short-term lease, including carrying costs, were deferred in a regulatory asset as a recoverable cost under the 2021 Texas legislation and totaled $81 million and $89 million as of September 30, 2025 and December 31, 2024, respectively. Expenses associated with the long-term lease, including variable costs associated with the operation and maintenance of the TEEEF, depreciation expense on the right of use asset and carrying costs, are deferred in a regulatory asset as a recoverable cost under the 2021 Texas legislation and totaled $139 million and $158 million as of September 30, 2025 and December 31, 2024, respectively.

Right of use finance lease assets, such as assets acquired under the long-term leases, are evaluated for impairment under the long-lived asset impairment model by assessing if a capital disallowance from a regulator is probable through monitoring the outcome of rate cases and other proceedings. Houston Electric continues to monitor the ongoing proceedings and did not record any impairments or disallowances on its right of use assets or TEEEF regulatory assets in the three and nine months ended September 30, 2025 or September 30, 2024.

Effective January 1, 2023, all temporary generation assets were leased under the long-term lease agreement. The long-term lease agreement includes up to 505 MW of TEEEF, all of which was delivered as of December 31, 2022, triggering lease commencement at delivery, with an initial term ending in 2029 for all TEEEF leases. The remaining finance lease liability associated with the commenced long-term TEEEF agreement was not significant as of September 30, 2025 and December 31, 2024 and relates to removal costs that will be incurred at the end of the lease term. As of September 30, 2025, Houston Electric had secured a first lien on the assets leased under the prepayment agreement, except for assets with lease payments totaling $17 million, which is being held in an escrow account, not controlled by Houston Electric, and the funds will be released either pro rata each month or when a first lien can be secured by Houston Electric on such assets.

On September 11, 2024, the TCA filed a complaint with the PUCT requesting that the PUCT modify its rulings with respect to its prior decisions related to the TEEEF filings made in 2022 and 2023. Specifically, the TCA requested that the PUCT end cost recovery and return on investment on all the large up to 32 MW and 5 MW TEEEF units approved in Docket 53442. On October 2, 2024, Houston Electric filed a response to the TCA complaint and requested that the complaint be dismissed due to the principles of res judicata and collateral estoppel. On October 8, 2024, the TCA supplemented its complaint and on October 9, 2024, PUCT staff filed a statement of position stating that Houston Electric’s response provided a strong argument for dismissal of the complaint, but also stating that it would be prudent to have a thorough legal argument from the TCA. On October 10, 2024, the PUCT issued Order No. 2 finding the TCA complaint insufficient and requiring supplemental information or amendment from the TCA by October 24, 2024; the TCA filed supplemental information on October 24, 2024. On November 14, 2024, the PUCT issued Order No. 4 denying the motion to reconsider and extending a deadline. On December 16, 2024, the PUCT issued Order No. 5 granting waiver of the requirement for informal disposition and soliciting PUCT staff recommendation by January 16, 2025. On January 16, 2025, the PUCT staff filed a supplemental recommendation recommending that the TCA had not met its requirement to first present its complaint to the City of Houston prior to presenting it to the PUCT. On February 26, 2025, the TCA filed its complaint with the City of Houston. On April 1, 2025, the TCA filed the response from the City of Houston dated March 12, 2025, which stated the matter is closed and the City of Houston does not have the authority to re-visit these dockets. The City of Houston also stated that the TCA may appeal to the PUCT and then district court. On April 29, 2025, the PUCT staff filed a supplemental statement of position and motion to dismiss the TCA’s complaint due to lack of jurisdiction. On May 19, 2025, the PUCT issued Order No. 8 lifting the abatement and requiring parties to file responses indicating whether they wish to proceed with or without a hearing. In response to Order No. 8, Houston Electric and the PUCT staff filed responses on June 20, 2025, supporting the dismissal of the TCA’s complaint without a hearing. The TCA also filed a response on June 20, 2025, to request that the parties be allowed to delay responding to the request for a hearing in this docket until a final settlement is made in Docket 57980 (Houston Electric’s application to remove the 15 large 27 MW to 32 MW TEEEF units from its TEEEF fleet) or, if the request for delay is not granted, to request that the hearing in this docket be scheduled after the settlement of Docket 57980. On June 29, 2025, Order No. 9 was issued, granting the TCA’s request to abate this complaint case until a final order is issued in Docket 57980.

On December 19, 2024, Houston Electric announced a proposal to release its 15 large 27 MW to 32 MW TEEEF units to the San Antonio area prior to the summer of 2025. The proposal was intended to help ERCOT address a potential energy

shortfall and Load Shed risk. On April 18, 2025, a proposal was filed with the PUCT (Docket 57980), seeking approval of the aforementioned release to ERCOT, a corresponding reduction to TEEEF fleet capacity and a rate reduction to reflect the removal of the 15 large TEEEF units from Houston Electric’s TEEEF fleet. On June 4, 2025, Houston Electric entered into definitive documentation, subject to PUCT approval, to release the 15 large 27 MW to 32 MW TEEEF units to the San Antonio area for a period of up to two years, during which time Houston Electric will not receive revenue or profit from ERCOT and will not charge Houston-area customers for such TEEEF units while they remain in the San Antonio area serving ERCOT. Following the completion of service in the San Antonio area, Houston Electric anticipates that it would receive revenues from one or more future transactions involving various sizes of the TEEEF units, and therefore plans to continue to not charge customers for these units for any future periods. On June 5, 2025, certain intervenors submitted a joint request for hearing. On July 9, 2025, the PUCT referred this docket to the SOAH. The PUCT issued a preliminary order on July 10, 2025, listing the issues to be addressed. SOAH Order No. 1 required parties to confer and submit a proposed procedural schedule or request a prehearing conference by July 25, 2025. On July 25, 2025, Houston Electric requested a prehearing conference. On July 28, 2025, SOAH Order No. 2 was issued, setting a prehearing conference for August 22, 2025. On August 21, 2025, Houston Electric filed a joint proposed procedural schedule. On August 22, 2025, SOAH Order No. 3 was issued and cancelled the prehearing conference, adopted the procedural schedule, set the prehearing conference for November 12, 2025 and set the hearing on the merits for November 13 through November 14, 2025. On October 13, 2025, intervenor testimony was filed. PUCT staff testimony is due on October 23, 2025.

Following the passage of legislation in 2023 that allows for wider uses for TEEEF, Houston Electric entered into a lease with Energy Rental Solutions (“ERS”) to add smaller 200 kW to one MW TEEEF units to its existing TEEEF fleet. In response to both the May 2024 Storm Events and Hurricane Beryl, Houston Electric extended its lease with ERS and secured additional small TEEEF units under the ERS lease terms; the primary purpose of the smaller TEEEF units is to provide temporary electric service to medical facilities, cooling centers, assisted living facilities and critical care customers that are impacted by extended weather-related outages. Houston Electric’s lease with ERS expired on March 31, 2025, after the PUCT adopted the TEEEF Rule, which went into effect on January 8, 2025 and refined the scope of TEEEF filings that can be made pursuant to applicable Texas regulations. Among other things, the TEEEF Rule has specific provisions relating to when and how utilities must request PUCT authorization to lease TEEEF units, and it generally requires a utility to obtain preapproval prior to renewing or entering into a new lease of TEEEF units. Houston Electric believes that it continues to need small TEEEF units, and on May 27, 2025, Houston Electric filed an application pursuant to the TEEEF Rule requesting preapproval to enter into two leases for a combined approximately 20 MW of TEEEF capacity comprised of 36 small TEEEF units, each with a capacity range of 200 kW to 1,250 kW, for respective terms of 36 months. Approval of Houston Electric’s request in this filing will have no cost impact on customers at this time because cost determination will occur in a future proceeding. On July 28, 2025, the Texas Office of Public Utility Counsel requested a hearing. On August 26, 2025, Houston Electric and an intervenor each filed a list of issues. On September 9, 2025, the PUCT issued an order of referral to SOAH and requested assignment of an ALJ. A preliminary order providing a non-exhaustive list of issues that must be addressed was issued on September 11, 2025. On September 16, 2025, SOAH Order No. 1 was issued, ordering the parties to confer and submit a proposed procedural schedule or request a prehearing conference by September 26, 2025. On September 26, 2025, SOAH Order No. 2 was issued, extending the deadline to submit a proposed procedural schedule until October 3, 2025 and stating that this deadline may be further extended without order by agreement of the parties. On October 3, 2025, Houston Electric filed a letter of notification providing that all parties were engaged in constructive settlement talks and requested an abatement until October 17, 2025. On October 13, 2025, Houston Electric filed errata and supplemental testimony to modify its application to instead request preapproval of just one lease for all 36 small TEEEF units. On October 17, 2025, Houston Electric filed a letter indicating that the parties continue to engage in productive settlement negotiations and plan to file settlement documents or another status update by October 31, 2025.

May 2024 Storm Events

Houston Electric’s electric delivery system suffered significant damage as a result of the May 2024 Storm Events. As is common with electric utilities serving coastal regions, the poles, towers, wires, street lights and pole-mounted equipment that comprise Houston Electric’s transmission and distribution system are not covered by property insurance.

On November 8, 2024, Houston Electric filed an Application for Determination of System Restoration Costs with the PUCT to determine the reasonableness and necessity of approximately $502 million of costs (including estimated case processing expenses and carrying costs) incurred or expected to be incurred to restore service following the May 2024 Storm Events. On March 19, 2025, Houston Electric filed a settlement agreement with the PUCT, under which Houston Electric would be entitled to recover a total of $396 million in distribution-related costs relating to the May 2024 Storm Events, along with carrying costs from the date those costs were incurred until system restoration bonds are issued. The settlement agreement also provided for the recovery of $29 million in transmission-related costs related to the May 2024 Storm Events that will be eligible for recovery through existing mechanisms established to recover transmission costs. Houston Electric agreed to defer

$17.5 million of its distribution-related costs to the Hurricane Beryl cost determination proceeding and further agreed to an overall $10 million reduction in costs as part of the settlement agreement. A final order approving the settlement agreement was issued by the PUCT on April 24, 2025. On January 24, 2025, Houston Electric filed a request for a Financing Order for the distribution costs included in the November 8, 2024 Application for Determination of System Restoration Costs. On April 23, 2025, Houston Electric filed a settlement agreement with the PUCT, under which Houston Electric would be entitled to securitize the approved distribution-related costs. A final order approving the settlement agreement was issued by the PUCT on June 5, 2025. The PUCT issued an irrevocable Financing Order on June 5, 2025, which became final and non-appealable on June 20, 2025.

In connection with the securitization of the system restoration costs incurred in connection with the May 2024 Storm Events, on June 20, 2025, Houston Electric and Restoration Bond Company II filed a registration statement, as amended on August 13, 2025 and as further amended on August 27, 2025, on Form SF-1 under the Securities Act with the SEC registering the public offering and sale of up to approximately $401.5 million aggregate principal amount of the May 2024 Storm Events System Restoration Bonds. The registration statement became effective on September 8, 2025. See Note 9 for additional detail on the issuance of the May 2024 Storm Events System Restoration Bonds.

Hurricane Beryl and Subsequent Storm Events

In 2024 and early 2025, Houston Electric’s service territory was damaged as a result of Hurricane Beryl and certain other significant storms. Houston Electric is deferring the related system restoration costs as management believes it is probable that such costs will be recovered through the regulatory process. The ultimate recovery of the system restoration costs (or a portion thereof) is expected to be sought through the issuance and sale of non-recourse securitization bonds for distribution-related costs. However, neither the amount nor timing of the recovery of the system restoration costs is certain.

On May 2, 2025, Houston Electric filed an Application for Determination of System Restoration Costs with the PUCT to determine the reasonableness and necessity of approximately $1.3 billion of costs (including estimated case processing expenses and carrying costs) incurred or expected to be incurred to restore service following Hurricane Beryl and certain other significant storms. Intervenor direct testimony was filed on June 30, 2025 and PUCT staff direct testimony was filed on July 3, 2025. Intervenor and PUCT staff disallowance positions totaled about $298.8 million and $4.7 million, respectively. Houston Electric’s rebuttal testimony was filed on July 18, 2025. On August 14, 2025, Houston Electric filed a settlement agreement with the PUCT, under which Houston Electric would be entitled to recover a total of $1.1 billion in distribution-related costs, along with carrying costs from the date those costs were incurred until the system restoration bonds are issued. The settlement agreement also provided for the recovery of $13 million in transmission-related costs that will be eligible for recovery through existing mechanisms established to recover transmission costs. As part of the settlement agreement, Houston Electric agreed to defer $78 million of its distribution-related costs to a regulatory asset and may request recovery and, if eligible, securitization of the deferral in a future rate case. Houston Electric further agreed as part of the settlement agreement to an overall $22 million reduction in distribution-related costs, which is comprised of shareholder equity carrying costs, and a $440,000 reduction in transmission-related costs, which is also comprised of shareholder equity carrying costs. On October 2, 2025, the PUCT voted to approve the settlement agreement with a modification to remove municipal legal fees and consulting and non-consulting fees from the securitization amount and defer such costs in a regulatory asset for recovery in a future ratemaking proceeding. On October 22, 2025, Houston Electric filed a letter to affirm the removal of $2.9 million of municipal legal fees and consulting and non-consulting fees from the securitization amount and defer these costs until a future rate making proceeding.
