DPL Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

For the three and nine months ended September 30, 2024 and 2023

1. OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DPL, an indirectly wholly-owned subsidiary of AES, is a holding company organized in 1985 under the laws of Ohio. DPL owns all of the outstanding common stock of DP&L, which does business as AES Ohio. Substantially all of DPL’s business consists of transmitting, distributing and selling of electric energy conducted through its principal subsidiary, AES Ohio. The terms “we,” “us,” “our” and “ours” are used to refer to DPL and its subsidiaries.

AES Ohio is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave Ohio consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, retail transmission and distribution services are still regulated. AES Ohio has the exclusive right to provide such transmission and distribution services to approximately 541,000 customers located in West Central Ohio. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. AES Ohio also provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. AES Ohio sources all of the generation for its SSO customers through a competitive bid process. AES Ohio's sales reflect the general economic conditions, seasonal weather patterns of the area, the market price of electricity and customer energy efficiency initiatives. AES Ohio owns numerous transmission facilities. AES Ohio records revenue and expenses for its proportional share of energy and capacity from its investment in OVEC.

DPL’s other primary subsidiaries are MVIC and Miami Valley Lighting. MVIC is our captive insurance company that provides insurance services to AES Ohio and our other subsidiaries, and Miami Valley Lighting provides street and outdoor lighting services to customers in the Dayton region. DPL's subsidiaries are all wholly-owned. DPL also has a wholly-owned business trust, DPL Capital Trust II, formed for the purpose of issuing trust capital securities to investors.

AES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, AES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses and records regulatory assets when incurred costs are expected to be recovered in future customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs or overcollections of riders.

Agreement to Sell Minority Interest in AES Ohio

On September 13, 2024, DPL entered into (i) a Purchase and Sale Agreement with Astrid Holdings LP ("Investor"), a wholly-owned subsidiary of Caisse de dépôt et placement du Québec ("CDPQ"), pursuant to which DPL agreed to sell to Investor 15% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Holdings, Inc. ("Ohio Holdings" and, such agreement, the "Ohio Holdings Purchase Agreement") for a purchase price of approximately $273 million, subject to adjustment, and (ii) a Purchase and Sale Agreement with Investor, pursuant to which DPL agreed to sell to Investor 17.65% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Investments, Inc. ("Ohio Investments" and, such agreement, the "Ohio Investments Purchase Agreement" and together with the Ohio Holdings Purchase Agreement, the "Purchase Agreements") for a purchase price of approximately $273 million, subject to adjustment. Upon consummation of the transactions contemplated by the Ohio Holdings Purchase Agreement and the Ohio Investments Purchase Agreement together, the ("Closings"), CDPQ will own an aggregate indirect equity interest in AES Ohio of approximately 30%, with total proceeds to DPL of approximately $546 million, subject to adjustment.

It is anticipated that the Closings will occur on the same day in the first half of 2025. There will be no change in management or operational control of DPL, Ohio Investments, Ohio Holdings or AES Ohio as a result of these transactions.

The purchases and sales of the shares of capital stock of each of Ohio Holdings and Ohio Investments contemplated under each of the Purchase Agreements are subject to the satisfaction of certain customary conditions described in the Purchase Agreements, including, among others, receipt of the approval of the Public Utilities Commission of Ohio, the Federal Energy Regulatory Commission and completion of review by the Committee on Foreign Investments in the United States. In addition, each of the parties to the Purchase Agreements has agreed to customary covenants therein.

16

In connection with the Closings, Investor, Ohio Investments and DPL will enter into a Shareholders' Agreement with respect to Ohio Investments (the "Shareholders' Agreement"), the form of which has been agreed to by the parties. The Shareholders' Agreement will establish the general framework governing the relationship between and among Investor and the Company, and their respective successors and transferees, as shareholders of Ohio Investments. In addition, Investor, Ohio Holdings and Ohio Investments will also enter into a Shareholders' Agreement with respect to Ohio Holdings with substantially identical terms.

Consolidation

DPL’s Condensed Consolidated Financial Statements include the accounts of DPL and its wholly-owned subsidiaries except for DPL Capital Trust II, which is not consolidated consistent with the provisions of GAAP. All material intercompany accounts and transactions are eliminated in consolidation. We have evaluated subsequent events through the date this report was issued.

Interim Financial Presentation

The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASC, for interim financial information and Article 10 of Regulation S-X issued by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income or loss, changes in shareholder's equity, and cash flows. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of expected results for the year ending December 31, 2024. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2023 audited consolidated financial statements and footnotes thereto, which are included in our Form 10-K.

Use of Management Estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the revenue and expenses of the periods reported. Actual results could differ from these estimates and assumptions. Significant items subject to such estimates and assumptions include: the carrying value of property, plant and equipment; unbilled revenue; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits.

Reclassifications

Certain amounts from prior periods have been reclassified to conform to the current period presentation.

New Accounting Pronouncements Issued But Not Yet Effective

The following table provides a brief description of recent accounting pronouncements that could have an impact on our consolidated financial statements. Accounting pronouncements not listed below were assessed and determined to be either not applicable or are expected to have no material impact on our consolidated financial statements.

18

ASU Number and Name	Description	Date of Adoption	Effect on the financial statements upon adoption
2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures	The amendments in this section are designed to improve the disclosures related to segment reporting on an interim and annual basis. Public companies must disclose significant segment expenses and an amount for other segment items. This will also require that a company disclose its annual disclosures under Topic 280 in each interim period. Furthermore, companies will need to disclose the Chief Operating Decision Maker (“CODM”) and how the CODM assesses the performance of a segment. Lastly, public companies that have a single reportable segment must report the required disclosures under Topic 280.	The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted.	This ASU only affects disclosures, which will be provided when the amendment becomes effective.
2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures	The amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. Furthermore, companies are required to disclose a disaggregated amount of income taxes paid at a federal, state, and foreign level as well as a breakdown of income taxes paid in a jurisdiction that comprises 5% of a company's total income taxes paid. Lastly, this ASU requires that companies disclose income (loss) from continuing operations before income tax at a domestic and foreign level and that companies disclose income tax expense from continuing operations on a federal, state, and foreign level.	The amendments in this Update are effective for fiscal years beginning after December 15, 2024.	This ASU only affects disclosures, which will be provided when the amendment becomes effective.

2. REGULATORY MATTERS

Smart Grid Phase 2 Plan

In February 2024, AES Ohio filed a Smart Grid Phase 2 with the PUCO proposing to invest approximately $683 million in capital projects over a 10-year period following Smart Grid Phase 1, which ends June 2025. On September 13, 2024, AES Ohio reached a settlement with the PUCO Staff and other parties on the pending Smart Grid Phase 2 Application. The Settlement will provide for a four-year plan to invest $240.5 million of capital and $18.6 million of operations and maintenance expense related to grid modernization, support of Distributed Energy Resources and Economic Development and an enhanced Telecommunications network. These costs will be recovered through the existing Investment Infrastructure Rider. If approved, AES Ohio will implement a comprehensive grid modernization project that will deliver benefits to customers, society as a whole and to AES Ohio. An evidentiary hearing was held on October 29, 2024, and we expect an order from the PUCO by the second quarter of 2025, prior to the end of Smart Grid Phase 1.

3. FAIR VALUE

The fair value of our financial assets and liabilities approximates their reported carrying amounts. The estimated fair values of our assets and liabilities have been determined using available market information. Because these amounts are estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. For further information on our valuation techniques and policies, see Note 4. Fair Value in Item 8. Financial Statements and Supplementary Data of our Form 10-K.

Financial Assets

AES Ohio established a Master Trust to hold assets that could be used for the benefit of employees participating in employee benefit plans. These assets are not used for general operating purposes. These assets are primarily comprised of open-ended mutual funds, which are valued using the net asset value per unit. These assets are recorded at fair value within Other non-current assets on the Condensed Consolidated Balance Sheets and are classified as equity investments. Net unrealized gains / (losses) related to equity investments still held as of September 30, 2024 and 2023 are as follows:

	Three months ended				Nine months ended
	September 30,				September 30,
$ in millions	2024		2023		2024		2023
Net unrealized gains / (losses) (a)	$	0.4	$	(0.2)	$	0.7	$	0.2

(a)    These amounts are included in Other income, net in our Condensed Consolidated Statements of Operations.

19

We did not have any transfers of the fair values of our financial instruments between Level 1, Level 2 or Level 3 of the fair value hierarchy during the nine months ended September 30, 2024 or 2023.

Recurring Fair Value Measurements

The fair value of assets and liabilities as of September 30, 2024 and December 31, 2023 measured on a recurring basis and the respective category within the fair value hierarchy for DPL is as follows:

	Fair value as of September 30, 2024								Fair value as of December 31, 2023
$ in millions	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total

Mutual funds	7.8		—		—		7.8		7.2		—		—		7.2
Total assets	$	8.1	$	—	$	—	$	8.1	$	7.8	$	—	$	—	$	7.8

Financial Instruments not Measured at Fair Value in the Condensed Consolidated Balance Sheets

The fair value of long-term debt is based on current public market prices for disclosure purposes only. These fair value inputs are considered Level 2 in the fair value hierarchy. As the Wright-Patterson Air Force Base note is not publicly traded, the fair value inputs are considered Level 3 in the fair value hierarchy as there are no observable inputs. Unrealized gains or losses are not recognized in the financial statements as long-term debt is presented at carrying value, net of unamortized premium or discount and unamortized deferred financing costs. The long-term debt amounts include the current portion payable in the next twelve months and have maturities that range from 2025 to 2061.

The following table presents the carrying amount, fair value, and fair value hierarchy of our financial liabilities that are not measured at fair value in the Condensed Consolidated Balance Sheets as of the periods indicated, but for which fair value is disclosed:

	September 30, 2024										December 31, 2023
	Carrying Amount		Fair Value								Carrying Amount		Fair Value
$ in millions			Level 1		Level 2		Level 3		Total				Level 1		Level 2		Level 3		Total

Long-term debt	$	1,839.3	$	—	$	1,725.2	$	16.7	$	1,741.9	$	1,837.6	$	—	$	1,706.2	$	16.8	$	1,723.0

4. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

For further information on our derivative and hedge accounting policies, see Note 1. Overview and Summary of Significant Accounting Policies – Financial Derivatives and Note 5. Derivative Instruments and Hedging Activities of Item 8. Financial Statements and Supplementary Data in our Form 10-K.

Cash Flow Hedges

DPL previously used derivative financial instruments primarily to manage the interest rate risk associated with our long-term debt. These interest rate derivative contracts were settled in 2013, and we continue to amortize amounts out of AOCL into interest expense.

20

The following tables provide information concerning gains recognized in AOCL for the cash flow hedges for the three and nine months ended September 30, 2024 and 2023:

(b)First mortgage bonds issued to the OAQDA, to secure the loan of proceeds from tax-exempt bonds issued by the OAQDA. The bonds have a final maturity date of January 1, 2034 but are subject to a mandatory put in June 2027.

(c)Note payable to related party.

Revolving credit agreements

As of September 30, 2024 and December 31, 2023, the AES Ohio Credit Agreement had outstanding borrowings of $45.0 million and $15.0 million, respectively.

Significant Transactions

In August 2024, AES Ohio entered into an unsecured $150.0 million 364-day term loan agreement ("AES Ohio Term Loan"). The AES Ohio Term Loan was fully drawn at closing with the proceeds being used for general corporate purposes. This agreement matures on August 13, 2025, and bears interest at variable rates as described in the $150 million Term Loan Agreement. The AES Ohio Term Loan contains customary representations, warranties and

21

covenants, including a leverage covenant consistent with the leverage covenant contained in AES Ohio's Credit Agreement. AES Ohio has classified the AES Ohio Term Loan as short-term indebtedness as it matures in August 2025. Management plans to repay the AES Ohio Term Loan Agreement through a combination of funds from debt financings and parent equity capital contributions.

DPL's Senior unsecured notes

DPL has $415.0 million of 4.125% Senior unsecured notes due July 1, 2025 ("2025 DPL Notes"). Although current liquid funds are not sufficient to repay the amounts due under the 2025 DPL Notes at maturity, we will use a portion of the proceeds from the Closings to repay the notes in full (see Note 1. Overview and Summary of Significant Accounting Policies - Agreement to Sell Minority Interest in AES Ohio for more information).

Long-term debt covenants and restrictions

The AES Ohio Credit Agreement, AES Ohio Term Loan, and Fifty-Third, Fifty-Fourth and Fifty-Fifth Supplemental Indentures to the First Mortgage, pursuant to which the 3.20% Bonds due 2040, the 5.19% Bonds due 2033, the 5.49% Bonds due 2028 and the 5.70% Bonds due 2033 were issued, respectively, each contain one financial covenant. The covenant measures Total Debt to Total Capitalization and is calculated, at the end of each fiscal quarter, by dividing total debt at the end of the quarter by total capitalization at the end of the quarter. AES Ohio’s Total Debt to Total Capitalization ratio shall not be greater than 0.67 to 1.00. As of September 30, 2024, AES Ohio was in compliance with this financial covenant.

AES Ohio does not have any meaningful restrictions in its debt financing documents prohibiting dividends and return of capital payments to its parent, DPL. As of September 30, 2024, AES Ohio was in compliance with all debt covenants, including the financial covenant described above.

Substantially all property, plant & equipment of AES Ohio is subject to the lien of the mortgage securing AES Ohio’s First and Refunding Mortgage.

6. INCOME TAXES

DPL’s provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. The effective combined state and federal income tax rates were as follows:

	Three months ended				Nine months ended
	September 30,				September 30,
	2024		2023		2024		2023
Effective tax rate	(267.9)	%	19.9	%	(24.9)	%	13.3	%

The year-to-date rate is different from the combined federal and state statutory rate of 22.4% primarily due to the flowthrough of the net tax benefit related to the reversal of excess deferred taxes of AES Ohio as a percentage of pre-tax book income or loss. AES Ohio began amortizing a deferred municipal tax shortage in September 2023, which partially offsets the ongoing amortization of the TCJA benefit.

DPL's income tax expense for the nine months ended September 30, 2024 was calculated using the estimated annual effective income tax rate for 2024 of (53.1)% on ordinary income. Management estimates the annual effective tax rate based on its forecast of annual pre-tax income or loss. DPL's current period tax benefit was calculated using the limitations prescribed in ASC 740-270-30-30 through 740-270-30-33.

AES files federal and state income tax returns, which consolidate DPL and its subsidiaries. Under a tax sharing agreement with AES, DPL is responsible for the income taxes associated with its own taxable income and records the provision for income taxes using a separate return method.

7. BENEFIT PLANS

The amounts presented in the following tables for pension include both of the Pension Plans. The pension costs below have not been adjusted for amounts billed to the Service Company for former AES Ohio employees who are now employed by the Service Company or other AES affiliates that are still participants in the AES Ohio plans.

22

The following table presents the net periodic benefit cost of the Pension Plans for the three and nine months ended September 30, 2024 and 2023:

	Three months ended				Nine months ended
	September 30,				September 30,
$ in millions	2024		2023		2024		2023
Service cost	$	0.7	$	0.8	$	1.9	$	2.2
Interest cost	3.6		3.9		11.0		11.9
Expected return on plan assets	(3.7)		(4.4)		(11.1)		(13.2)
Amortization of unrecognized:
Prior service cost	0.2		0.3		0.7		0.8
Actuarial loss	0.5		0.2		1.6		0.5
Net periodic benefit cost	$	1.3	$	0.8	$	4.1	$	2.2

The components of net periodic benefit cost other than service cost are included in Other income, net in the Condensed Consolidated Statements of Operations.

There were $7.5 million in employer contributions during each of the nine month periods ended September 30, 2024 and 2023.

In addition, AES Ohio provides postretirement health care and life insurance benefits to certain retired employees, their spouses and eligible dependents. We have funded a portion of the union-eligible benefits using a Voluntary Employee Beneficiary Association Trust. These postretirement health care benefits and the related unfunded obligation were not material to the financial statements in the periods covered by this report.

8. SHAREHOLDER'S EQUITY

During the nine months ended September 30, 2024, DPL received $200.0 million in equity contributions from AES. DPL then made the same investment in AES Ohio.

During the nine months ended September 30, 2023, DPL received $260.0 million in cash contributions from AES. DPL then made the same investment in AES Ohio. The proceeds from the cash contributions at DPL represented equity contributions of $239.0 million and payments of $21.0 million against the tax receivable from AES.

The proceeds from these equity contributions allow AES Ohio to seek to improve its infrastructure and modernize its grid while maintaining liquidity.

9. COMMITMENTS AND CONTINGENCIES

Contingencies

Legal Matters

In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under various laws and regulations. We believe the amounts provided in our Condensed Consolidated Financial Statements, as prescribed by GAAP, are adequate considering the probable and estimable contingencies. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various legal proceedings, claims, tax examinations and other matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in our Condensed Consolidated Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided as of September 30, 2024, cannot be reasonably determined.

Environmental Matters

We are subject to various federal, state, regional and local environmental protection and health and safety laws and regulations governing, among other things, the generation, storage, handling, use, disposal and transportation of regulated materials, including ash and CCR; the use and discharge of water used in generation boilers and for cooling purposes; the emission and discharge of hazardous and other materials, including GHGs, into the environment; climate change; species and habitat protections; and the health and safety of our employees. These laws and regulations often require a lengthy and complex process of obtaining and renewing permits and other governmental authorizations from federal, state and local agencies. Violation of these laws, regulations or permits

23

can result in substantial fines, other sanctions, permit revocation and/or facility shutdowns. We cannot assure that we have been or will be at all times in full compliance with such laws, regulations and permits.

Where no accrued liability has been recognized, it is reasonably possible that some matters could be decided unfavorably to us and could require us to pay damages or make expenditures in amounts that could be material but could not be estimated as of September 30, 2024.

We have taken steps to limit our exposure to environmental claims that could be raised with respect to our previously-owned and operated coal-fired generation units, but we cannot predict whether any such claims will be raised and, if they are, the extent to which they may have a material adverse effect on our results of operations, financial condition and cash flows.

Accruals for legal loss and environmental contingencies were not material as of September 30, 2024 and December 31, 2023.

Equity Ownership Interest

AES Ohio has a 4.9% equity ownership interest in OVEC, which is recorded using the cost method of accounting under GAAP. AES Ohio, along with several non-affiliated energy companies party to an OVEC arrangement, receive and pay for OVEC capacity and energy and are responsible for OVEC debt obligations and other fixed costs in proportion to their power participation ratios under the arrangement, which, for AES Ohio, is the same as its equity ownership interest. As of September 30, 2024, AES Ohio could be responsible for the repayment of 4.9%, or $49.7 million, of $1.0 billion OVEC debt obligations if they came due, comprised of fixed rate securities with maturities from 2026 to 2040. OVEC could also seek additional contributions from AES Ohio to avoid a default in the event that other OVEC members defaulted on their respective OVEC obligations.

10. BUSINESS SEGMENTS

DPL manages its business through one reportable operating segment, the Utility segment. The primary segment performance measure is income / (loss) before income tax as management has concluded that this measure best reflects the underlying business performance of DPL and is the most relevant measure considered in DPL’s internal evaluation of the financial performance of its segment. The Utility segment is comprised of AES Ohio, a public electric transmission and distribution utility, with all other nonutility business activities aggregated separately. See Note 1. Overview and Summary of Significant Accounting Policies for further information on AES Ohio. The “Other” nonutility category primarily includes interest expense, cash and other immaterial balances. The accounting policies of the identified segment are consistent with those policies and procedures described in the summary of significant accounting policies.

The following tables present financial information for DPL’s reportable business segment:

11. REVENUE

Revenue is primarily earned from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities. For further discussion of our Retail, Wholesale, RTO ancillary, and Capacity revenue, see Note 13. Revenue in Item 8. Financial Statements and Supplementary Data of our Form 10-K.

Notes to Unaudited Condensed Financial Statements

For the three and nine months ended September 30, 2024 and 2023

1. OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DP&L, which does business as AES Ohio, is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave Ohio consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, retail transmission and distribution services are still regulated. AES Ohio has the exclusive right to provide such transmission and distribution services to approximately 541,000 customers located in West Central Ohio. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. AES Ohio also provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. AES Ohio sources all of the generation for its SSO customers through a competitive bid process. AES Ohio's sales reflect the general economic conditions, seasonal weather patterns of the area, the market price of electricity and customer energy efficiency initiatives. AES Ohio owns numerous transmission facilities. AES Ohio records revenue and expenses for its proportional share of energy and capacity from its investment in OVEC. AES Ohio has one reportable segment, the Utility segment. In addition to AES Ohio's electric transmission and distribution businesses, the Utility segment includes revenue and expenses associated with AES Ohio's investment in OVEC. AES Ohio is a subsidiary of DPL. The terms “we,” “us,” “our” and “ours” are used to refer to AES Ohio.

AES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, AES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses and records regulatory assets when incurred costs are expected to be recovered in future customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs or overcollections of riders.

Agreement to Sell Minority Interest in AES Ohio

On September 13, 2024, DPL entered into (i) a Purchase and Sale Agreement with Astrid Holdings LP ("Investor"), a wholly-owned subsidiary of Caisse de dépôt et placement du Québec ("CDPQ"), pursuant to which DPL agreed to sell to Investor 15% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Holdings, Inc. ("Ohio Holdings" and, such agreement, the "Ohio Holdings Purchase Agreement") for a purchase price of approximately $273 million, subject to adjustment, and (ii) a Purchase and Sale Agreement with Investor, pursuant to which DPL agreed to sell to Investor 17.65% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Investments, Inc. ("Ohio Investments" and, such agreement, the "Ohio Investments Purchase Agreement" and together with the Ohio Holdings Purchase Agreement, the "Purchase Agreements") for a purchase price of approximately $273 million, subject to adjustment. Upon consummation of the transactions contemplated by the Ohio Holdings Purchase Agreement and the Ohio Investments Purchase Agreement together, the ("Closings"), CDPQ will own an aggregate indirect equity interest in AES Ohio of approximately 30%, with total proceeds to DPL of approximately $546 million, subject to adjustment.

It is anticipated that the Closings will occur on the same day in the first half of 2025. There will be no change in management or operational control of DPL, Ohio Investments, Ohio Holdings or AES Ohio as a result of these transactions.

The purchases and sales of the shares of capital stock of each of Ohio Holdings and Ohio Investments contemplated under each of the Purchase Agreements are subject to the satisfaction of certain customary conditions described in the Purchase Agreements, including, among others, receipt of the approval of the Public Utilities Commission of Ohio, the Federal Energy Regulatory Commission and completion of review by the Committee on Foreign Investments in the United States. In addition, each of the parties to the Purchase Agreements has agreed to customary covenants therein.

In connection with the Closings, Investor, Ohio Investments and DPL will enter into a Shareholders' Agreement with respect to Ohio Investments (the "Shareholders' Agreement"), the form of which has been agreed to by the parties. The Shareholders' Agreement will establish the general framework governing the relationship between and among Investor and the Company, and their respective successors and transferees, as shareholders of Ohio Investments. In addition, Investor, Ohio Holdings and Ohio Investments will also enter into a Shareholders' Agreement with respect to Ohio Holdings with substantially identical terms.

Financial Statement Presentation

AES Ohio does not have any subsidiaries. We have evaluated subsequent events through the date this report was issued.

Interim Financial Presentation

The accompanying unaudited condensed financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASC, for interim financial information and Article 10 of Regulation S-X issued by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income or loss, changes in shareholder's equity, and cash flows. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of expected results for the year ending December 31, 2024. The accompanying condensed financial statements are unaudited and should be read in conjunction with the 2023 audited financial statements and footnotes thereto, which are included in our Form 10-K.

Use of Management Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the revenue and expenses of the periods reported. Actual results could differ from these estimates and assumptions. Significant items subject to such estimates and assumptions include: the carrying value of property, plant and equipment; unbilled revenue; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits.

Reclassifications

Certain amounts from prior periods have been reclassified to conform to the current period presentation.

New Accounting Pronouncements Issued But Not Yet Effective

The following table provides a brief description of recent accounting pronouncements that could have an impact on our financial statements. Accounting pronouncements not listed below were assessed and determined to be either not applicable or are expected to have no material impact on our consolidated financial statements.

ASU Number and Name	Description	Date of Adoption	Effect on the financial statements upon adoption
2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures	The amendments in this section are designed to improve the disclosures related to segment reporting on an interim and annual basis. Public companies must disclose significant segment expenses and an amount for other segment items. This will also require that a company disclose its annual disclosures under Topic 280 in each interim period. Furthermore, companies will need to disclose the Chief Operating Decision Maker (“CODM”) and how the CODM assesses the performance of a segment. Lastly, public companies that have a single reportable segment must report the required disclosures under Topic 280.	The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted.	This ASU only affects disclosures, which will be provided when the amendment becomes effective.
2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures	The amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. Furthermore, companies are required to disclose a disaggregated amount of income taxes paid at a federal, state, and foreign level as well as a breakdown of income taxes paid in a jurisdiction that comprises 5% of a company's total income taxes paid. Lastly, this ASU requires that companies disclose income (loss) from continuing operations before income tax at a domestic and foreign level and that companies disclose income tax expense from continuing operations on a federal, state, and foreign level.	The amendments in this Update are effective for fiscal years beginning after December 15, 2024.	This ASU only affects disclosures, which will be provided when the amendment becomes effective.

2. REGULATORY MATTERS

Smart Grid Phase 2 Plan

In February 2024, AES Ohio filed a Smart Grid Phase 2 with the PUCO proposing to invest approximately $683 million in capital projects over a 10-year period following Smart Grid Phase 1, which ends June 2025. On September 13, 2024, AES Ohio reached a settlement with the PUCO Staff and other parties on the pending Smart Grid Phase 2 Application. The Settlement will provide for a four-year plan to invest $240.5 million of capital and $18.6 million of operations and maintenance expense related to grid modernization, support of Distributed Energy Resources and Economic Development and an enhanced Telecommunications network. These costs will be recovered through the existing Investment Infrastructure Rider. If approved, AES Ohio will implement a comprehensive grid modernization project that will deliver benefits to customers, society as a whole and to AES Ohio. An evidentiary hearing was held on October 29, 2024, and we expect an order from the PUCO by the second quarter of 2025, prior to the end of Smart Grid Phase 1.

3. FAIR VALUE

The fair value of our financial assets and liabilities approximates their reported carrying amounts. The estimated fair values of our assets and liabilities have been determined using available market information. Because these amounts are estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. For further information on our valuation techniques and policies, see Note 4. Fair Value in Item 8. – Financial Statements and Supplementary Data of our Form 10-K.

Financial Assets

AES Ohio established a Master Trust to hold assets that could be used for the benefit of employees participating in employee benefit plans. These assets are not used for general operating purposes. These assets are primarily comprised of open-ended mutual funds, which are valued using the net asset value per unit. These assets are recorded at fair value within Other non-current assets on the Condensed Balance Sheets and are classified as

37

equity investments. Net unrealized gains / (losses) related to equity investments still held as of September 30, 2024 and 2023 are as follows:

	Three months ended				Nine months ended
	September 30,				September 30,
$ in millions	2024		2023		2024		2023
Net unrealized gains (a)	$	0.4	$	(0.2)	$	0.7	$	0.2

(a)    These amounts are included in Other income, net in our Condensed Statements of Operations.

We did not have any transfers of the fair values of our financial instruments between Level 1, Level 2 or Level 3 of the fair value hierarchy during the nine months ended September 30, 2024 or 2023.

Recurring Fair Value Measurements

The fair value of assets and liabilities as of September 30, 2024 and December 31, 2023 measured on a recurring basis and the respective category within the fair value hierarchy for AES Ohio is as follows:

	Fair value as of September 30, 2024								Fair value as of December 31, 2023
$ in millions	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total

Total assets	$	8.1	$	—	$	—	$	8.1	$	7.8	$	—	$	—	$	7.8

Financial Instruments not Measured at Fair Value in the Condensed Balance Sheets

The fair value of long-term debt is based on current public market prices for disclosure purposes only. These fair value inputs are considered Level 2 in the fair value hierarchy. As the Wright-Patterson Air Force Base note is not publicly traded, the fair value inputs are considered Level 3 in the fair value hierarchy as there are no observable inputs. Unrealized gains or losses are not recognized in the financial statements as long-term debt is presented at carrying value, net of unamortized premium or discount and unamortized deferred financing costs. The long-term debt amounts include the current portion payable in the next twelve months and have maturities that range from 2027 to 2061.

The following table presents the carrying amount, fair value, and fair value hierarchy of our financial liabilities that are not measured at fair value in the Condensed Balance Sheets as of the periods indicated, but for which fair value is disclosed:

	September 30, 2024										December 31, 2023
	Carrying Amount		Fair Value								Carrying Amount		Fair Value
$ in millions			Level 1		Level 2		Level 3		Total				Level 1		Level 2		Level 3		Total

(a)First mortgage bonds issued to the OAQDA, to secure the loan of proceeds from tax-exempt bonds issued by the OAQDA. The bonds have a final maturity date of November 1, 2040 but are subject to a mandatory put in June 2027.

(b)First mortgage bonds issued to the OAQDA, to secure the loan of proceeds from tax-exempt bonds issued by the OAQDA. The bonds have a final maturity date of January 1, 2034 but are subject to a mandatory put in June 2027.

Revolving credit agreements

As of September 30, 2024 and December 31, 2023, the AES Ohio Credit Agreement had outstanding borrowings of $45.0 million and $15.0 million, respectively.

Significant Transactions

In August 2024, AES Ohio entered into an unsecured $150.0 million 364-day term loan agreement ("AES Ohio Term Loan"). The AES Ohio Term Loan was fully drawn at closing with the proceeds being used for general corporate purposes. This agreement matures on August 13, 2025, and bears interest at variable rates as described in the $150 million Term Loan Agreement. The AES Ohio Term Loan contains customary representations, warranties and covenants, including a leverage covenant consistent with the leverage covenant contained in AES Ohio's Credit Agreement. AES Ohio has classified the AES Ohio Term Loan as short-term indebtedness as it matures in August 2025. Management plans to repay the AES Ohio Term Loan Agreement through a combination of funds from debt financings and parent equity capital contributions.

Long-term debt covenants and restrictions

The AES Ohio Credit Agreement, AES Ohio Term Loan, and Fifty-Third, Fifty-Fourth and Fifty-Fifth Supplemental Indentures to the First Mortgage, pursuant to which the 3.20% Bonds due 2040, the 5.19% Bonds due 2033, the 5.49% Bonds due 2028 and the 5.70% Bonds due 2033 were issued, respectively, each contain one financial covenant. The covenant measures Total Debt to Total Capitalization and is calculated, at the end of each fiscal quarter, by dividing total debt at the end of the quarter by total capitalization at the end of the quarter. AES Ohio’s Total Debt to Total Capitalization ratio shall not be greater than 0.67 to 1.00. As of September 30, 2024, AES Ohio was in compliance with this financial covenant.

As of September 30, 2024, AES Ohio was in compliance with all debt covenants, including the financial covenant described above.

AES Ohio does not have any meaningful restrictions in its debt financing documents prohibiting dividends and return of capital payments to its parent, DPL.

Substantially all property, plant & equipment of AES Ohio is subject to the lien of the mortgage securing AES Ohio’s First and Refunding Mortgage.

39

5. INCOME TAXES

AES Ohio's provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. The effective combined state and federal income tax rates were as follows:

	Three months ended				Nine months ended
	September 30,				September 30,
	2024		2023		2024		2023
Effective combined state and federal income tax rates	(17.9)	%	20.9	%	10.2	%	17.6	%

The year-to-date rate is different from the combined federal and state statutory rate of 22.4% primarily due to the flowthrough of the net tax benefit related to the reversal of excess deferred taxes of AES Ohio as a percentage of pre-tax book income or loss. AES Ohio began amortizing a deferred municipal tax shortage in September 2023, which partially offsets the ongoing amortization of the TCJA benefit.

AES files federal and state income tax returns, which consolidate AES Ohio. Under a tax sharing agreement with DPL, AES Ohio is responsible for the income taxes associated with its own taxable income and records the provision for income taxes using a separate return method.

6. BENEFIT PLANS

The amounts presented in the following tables for pension include both of the Pension Plans. The pension costs below have not been adjusted for amounts billed to the Service Company for former AES Ohio employees who are now employed by the Service Company or other AES affiliates or for amounts billed to AES Ohio Generation for former employees that were employed by AES Ohio Generation that are still participants in the AES Ohio plans.

The following table presents the net periodic benefit cost of the Pension Plans for the three and nine months ended September 30, 2024 and 2023:

	Three months ended				Nine months ended
	September 30,				September 30,
$ in millions	2024		2023		2024		2023
Service cost	$	0.7	$	0.8	$	1.9	$	2.2
Interest cost	3.6		3.9		11.0		11.9
Expected return on plan assets	(3.7)		(4.4)		(11.1)		(13.2)
Amortization of unrecognized:
Prior service cost	0.3		0.2		0.7		0.8
Actuarial loss	0.9		0.3		2.9		0.9
Net periodic benefit cost	$	1.8	$	0.8	$	5.4	$	2.6

The components of net periodic benefit cost other than service cost are included in Other income, net in the Condensed Statements of Operations.

There were $7.5 million in employer contributions during each of the nine month periods ended September 30, 2024 and 2023.

In addition, AES Ohio provides postretirement health care and life insurance benefits to certain retired employees, their spouses and eligible dependents. We have funded a portion of the union-eligible benefits using a Voluntary Employee Beneficiary Association Trust. These postretirement health care benefits and the related unfunded obligation were not material to the financial statements in the periods covered by this report.

7. SHAREHOLDER'S EQUITY

During the nine months ended September 30, 2024, DPL made equity contributions of $200.0 million to AES Ohio.

During the nine months ended September 30, 2023, DPL made equity contributions of $260.0 million to AES Ohio.

The proceeds from these equity contributions allow AES Ohio to seek to improve its infrastructure and modernize its grid while maintaining liquidity.

8. COMMITMENTS AND CONTINGENCIES

Contingencies

Legal Matters

In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under various laws and regulations. We believe the amounts provided in our Condensed Financial Statements, as prescribed by GAAP, are adequate considering the probable and estimable contingencies. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various legal proceedings, claims, tax examinations and other matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in our Condensed Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided as of September 30, 2024, cannot be reasonably determined.

Environmental Matters

We are subject to various federal, state, regional and local environmental protection and health and safety laws and regulations governing, among other things, the generation, storage, handling, use, disposal and transportation of regulated materials, including ash and CCR; the use and discharge of water used in generation boilers and for cooling purposes; the emission and discharge of hazardous and other materials, including GHGs, into the environment; climate change; species and habitat protections; and the health and safety of our employees. These laws and regulations often require a lengthy and complex process of obtaining and renewing permits and other governmental authorizations from federal, state and local agencies. Violation of these laws, regulations or permits can result in substantial fines, other sanctions, permit revocation and/or facility shutdowns. We cannot assure that we have been or will be at all times in full compliance with such laws, regulations and permits.

Where no accrued liability has been recognized, it is reasonably possible that some matters could be decided unfavorably to us and could require us to pay damages or make expenditures in amounts that could be material but could not be estimated as of September 30, 2024.

We have taken steps to limit our exposure to environmental claims that could be raised with respect to our previously-owned and operated coal-fired generation units, but we cannot predict whether any such claims will be raised and, if they are, the extent to which they may have a material adverse effect on our results of operations, financial condition and cash flows.

Accruals for legal loss and environmental contingencies were not material as of September 30, 2024 and December 31, 2023.

Equity Ownership Interest

AES Ohio has a 4.9% equity ownership interest in OVEC, which is recorded using the cost method of accounting under GAAP. AES Ohio, along with several non-affiliated energy companies party to an OVEC arrangement, receive and pay for OVEC capacity and energy and are responsible for OVEC debt obligations and other fixed costs in proportion to their power participation ratios under the arrangement, which, for AES Ohio, is the same as its equity ownership interest. As of September 30, 2024, AES Ohio could be responsible for the repayment of 4.9%, or $49.7 million, of $1.0 billion OVEC debt obligations if they came due, comprised of fixed rate securities with maturities from 2026 to 2040. OVEC could also seek additional contributions from AES Ohio to avoid a default in the event that other OVEC members defaulted on their respective OVEC obligations.

9. REVENUE

Revenue is primarily earned from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities. For further discussion of our Retail, Wholesale, RTO ancillary, and Capacity revenue, see Note 11. Revenue in Item 8. Financial Statements and Supplementary Data of our Form 10-K.

EXECUTIVE SUMMARY

DPL

For the three months ended September 30, 2024, DPL's income before income tax of $2.8 million was lower by $45.4 million, or 94%, compared to the prior period income before income tax of $48.2 million, and, for the nine months ended September 30, 2024, DPL's income before income tax of $18.5 million was lower by $21.4 million, or 54%, compared to the prior period income before income tax of $39.9 million, primarily due to factors including, but not limited to:

DPL – Revenue

Retail customers, especially residential and commercial customers, consume more electricity on warmer and colder days. Therefore, our retail sales demand is affected by the number of heating and cooling degree-days occurring during a year. Cooling degree-days typically have a more significant effect than heating degree-days since some residential customers do not use electricity to heat their homes. Additionally, our retail revenue is affected by regulated rates and riders including the changes to our ESP described in Note 2. Regulatory Matters of our Form 10-K and Note 2. Regulatory Matters of DPL's Condensed Consolidated Financial Statements.

HEATING AND COOLING DEGREE-DAYS (a)
	Three months ended					Nine months ended

30-year average (b)
Heating degree-days	68	70				3,389	3,431
Cooling degree-days	691	684				1,003	992

(a)Heating and cooling degree-days are a measure of the relative heating or cooling required for a home or business. The heating degrees in a day are calculated as the degrees that the average actual daily temperature is below 65 degrees Fahrenheit. For example, if the average temperature on March 20th was 40 degrees Fahrenheit, the heating degrees for that day would be the 25-degree difference between 65 degrees and 40 degrees. Similarly, cooling degrees in a day are calculated as the degrees that the average actual daily temperature is above 65 degrees Fahrenheit.

(b)30-year average is computed from observed degree-days in the Dayton area on a trailing 30-year basis.

DPL – Depreciation and Amortization

During the three and nine months ended September 30, 2024, Depreciation and amortization increased $5.1 million and $8.5 million, respectively, compared to the same periods in the prior year, primarily due to additional assets placed in service.

DPL – Taxes Other Than Income Taxes

During the three and nine months ended September 30, 2024, Taxes other than income taxes increased $2.9 million and $7.0 million, respectively, compared to the same periods in the prior year. The increase was primarily the result of higher property taxes due to higher assessed values in the current year.

DPL – Interest Expense, Net

During the three and nine months ended September 30, 2024, Interest expense, net increased $13.3 and $17.0, respectively, compared to the same periods in the prior year. The increase was primarily due to the prior year

49

deferral of carrying costs associated with the approval of ESP 4, as well as new debt issuances at AES Ohio, partially offset by an increase in AFUDC debt.

Income tax expense / (benefit)	(7.5)	9.6	(17.1)	(178)	%	(4.6)	5.3	(9.9)	(187)	%

The decreases in income tax expense / (benefit) of $(17.1) million and $(9.9) million during the three and nine months ended September 30, 2024, respectively, compared to the same periods of the prior year were primarily driven by higher pre-tax income in the prior year, and an increase in the net tax benefit related to the reversal of excess deferred taxes of AES Ohio.

See Note 6. Income Taxes in the DPL's Condensed Consolidated Financial Statements for further discussion.

RESULTS OF OPERATIONS BY SEGMENT - DPL

DPL manages its business through one reportable operating segment, the Utility segment. The primary segment performance measure is income / (loss) before income tax as management has concluded that this measure best reflects the underlying business performance of DPL and is the most relevant measure considered in DPL’s internal evaluation of the financial performance of its segment. The Utility segment is comprised of AES Ohio, a public electric transmission and distribution utility, with all other nonutility business activities aggregated separately. See Note 1. Overview and Summary of Significant Accounting Policies of DPL's Condensed Consolidated Financial Statements for further information on AES Ohio. The “Other” nonutility category primarily includes interest expense, cash and other immaterial balances. The accounting policies of the identified segment are consistent with those policies and procedures described in the summary of significant accounting policies.

See PART I, ITEM 1., Note 10. Business Segments of DPL's Condensed Consolidated Financial Statements for more information regarding DPL’s reportable segment.

The following table presents DPL’s Income / (loss) before income tax by business segment:

AES Ohio – Revenue

Retail customers, especially residential and commercial customers, consume more electricity on warmer and colder days. Therefore, our retail sales demand is affected by the number of heating and cooling degree-days occurring during a year. Cooling degree-days typically have a more significant effect than heating degree-days since some residential customers do not use electricity to heat their homes. Additionally, our retail revenue is affected by regulated rates and riders including the changes to our ESP described in Note 2. Regulatory Matters of our Form 10-K and Note 2 – Regulatory Matters of AES Ohio's Condensed Financial Statements.

During the three and nine months ended September 30, 2024, Interest expense, net increased $13.1 million and $18.0 million, respectively, compared to the same periods in the prior year. The increase was primarily due to the

53

prior year deferral of carrying costs associated with the approval of ESP 4, as well as new debt issuances at AES Ohio, partially offset by an increase in AFUDC debt.

AES Ohio – Income Tax Expense / (Benefit)

	Three months ended					Nine months ended
	September 30,					September 30,
$ in millions	2024	2023	change	% change		2024	2023	change	% change
Income tax expense / (benefit)	(1.9)	11.5	(13.4)	(117)	%	4.2	11.3	(7.1)	(63)	%

The decreases in income tax expense / (benefit) of $(13.4) million and $(7.1) million during the three and nine months ended September 30, 2024, respectively, compared to the same periods of the prior year were primarily driven by higher pre-tax income in the prior year, and an increase in the net tax benefit related to the reversal of excess deferred taxes.

See Note 5. Income Taxes of AES Ohio's Condensed Financial Statements for further discussion.

KEY TRENDS AND UNCERTAINTIES

During 2024 and beyond, we expect our financial results will be primarily impacted by retail demand and weather. In addition, DPL's and AES Ohio's financial results are likely to be driven by other factors including, but not limited to:

•regulatory outcomes;

•the passage of new legislation, implementation of regulations or other changes in regulation; and

•the timely recovery of transmission and distribution expenditures.

If favorable outcomes related to these factors do not occur, or if the challenges described below and elsewhere in this Quarterly Report impact us more significantly than we currently anticipate, then these factors, or other factors unknown to us, may impact our operating income, net income and cash flows. We continue to monitor our operations and address challenges as they arise. For a discussion of the risks related to our business, see Item 1. Business and Item 1A. Risk Factors in our Form 10-K.

Operational

Capital Projects – Our construction projects have experienced some indications of delays and price increases due to supply chain disruptions; however, they are currently proceeding without material delays. For further discussion of our capital requirements, see PART I, ITEM 2. Management's Discussion and Analysis of Financial Condition and Results of Operations – Capital Resources and Liquidity of this Form 10-Q.

Macroeconomic and Political

U.S. Income Tax – The macroeconomic and political environments in the U.S. have changed in recent years. This could result in significant impacts to tax law.

Inflation – In the markets in which we operate, there have been higher rates of inflation recently. If inflation increases in our market, it may increase our expenses that we may not be able to pass through to customers. AES Ohio may have the ability to recover operations and maintenance costs through the regulatory process; however, timing impacts on recovery may vary. In addition, the SSO auction process has reflected current macroeconomic conditions in terms of pricing.

Interest Rates – In the U.S. there has been a rise in interest rates since 2021, and interest rates are expected to remain volatile in the near term. Although all of our existing DPL and AES Ohio long-term debt is at fixed rates, an increase in interest rates can have several impacts on our business. For our existing short-term debt under floating rate structures and any future debt refinancings or future new money financings, rising interest rates will increase future financing costs. Our floating rate debt is currently limited to short-term borrowings under the AES Ohio Credit Agreement. For future debt financings, DPL manages a hedging program to help reduce uncertainty and exposure to future interest rates.

Regulatory

DPL’s, AES Ohio’s and our other subsidiaries’ facilities and operations are subject to a wide range of regulations and laws by federal, state and local authorities. As well as imposing continuing compliance obligations, these laws

54

and regulations authorize the imposition of substantial penalties for noncompliance, including fines, injunctive relief and other sanctions. In the normal course of business, we have investigatory and remedial activities underway at these facilities and operations in an effort to comply, or to determine compliance, with such regulations. We record liabilities for losses that are probable and can be reasonably estimated. In addition to matters discussed or updated herein, our 2023 Form 10-K and Forms 10-Q previously filed with the SEC during 2024 describe other regulatory matters, which have not materially changed since those filings.

Smart Grid Phase 2 Plan - In February 2024, AES Ohio filed a Smart Grid Phase 2 with the PUCO proposing to invest approximately $683 million in capital projects over a 10-year period following Smart Grid Phase 1, which ends June 2025. On September 13, 2024, AES Ohio reached a settlement with the PUCO Staff and other parties on the pending Smart Grid Phase 2 Application. The Settlement will provide for a four-year plan to invest $240.5 million of capital and $18.6 million of operations and maintenance expense related to grid modernization, support of Distributed Energy Resources and Economic Development and an enhanced Telecommunications network. These costs will be recovered through the existing Investment Infrastructure Rider. If approved, AES Ohio will implement a comprehensive grid modernization project that will deliver benefits to customers, society as a whole and to AES Ohio. An evidentiary hearing was held on October 29, 2024, and we expect an order from the PUCO by the second quarter of 2025, prior to the end of Smart Grid Phase 1.

Distribution Rate Case - On October 30, 2024, AES Ohio filed a Pre-filing Notice of Intent to file an application to increase rates for distribution service. The Distribution Rate Case Application will be filed on November 29, 2024.

See PART I, ITEM 1., Note 2. Regulatory Matters of DPL's Condensed Consolidated Financial Statements and PART I, ITEM 1., Note 2. Regulatory Matters of AES Ohio's Condensed Financial Statements for further information regarding these and other regulatory matters.

Environmental

We have several pending environmental matters associated with our previously-owned stations. Some of these matters could have a material adverse effect on our results of operations, financial condition and cash flows.

As a result of DPL now not directly owning or operating any generating stations, the following environmental matters, regulations and requirements are now not expected to have a material impact on DPL:

•MATS and any associated regulatory or judicial processes;

•NAAQS; and

•recently finalized CAA Section 111(d) regulations for greenhouse gases from existing electric generating units.

Regulation of CCR

On October 19, 2015, an EPA rule regulating CCR under the Resource Conservation and Recovery Act as

nonhazardous solid waste became effective ("CCR Rule"). The rule established nationally applicable minimum

criteria for the disposal of CCR in new and currently operating landfills and surface impoundments, including

location restrictions, design and operating criteria, groundwater monitoring, corrective action and closure

requirements and post-closure care. The 2016 Water Infrastructure Improvements for the Nation Act ("WIIN Act"),

includes provisions to implement the CCR Rule through a state permitting program, or if the state chooses not to

participate, a possible federal permit program. The EPA has indicated that they will implement a phased approach to

amending the CCR Rule.

On May 8, 2024, the EPA published final revisions to the CCR Rule, which are effective on November 8, 2024. The final revisions expand the scope of CCR units regulated by the CCR rule to include legacy surface impoundments, inactive surface impoundments, and CCR management units.

The CCR Rule, current or proposed amendments to, or EPA interpretations of, the CCR Rule, the results of

groundwater monitoring data or the outcome of CCR-related litigation could have a material adverse effect on our

results of operations, financial condition and cash flows.

CAPITAL RESOURCES AND LIQUIDITY

OVERVIEW

DPL and AES Ohio had unrestricted cash and cash equivalents of $41.0 million and $19.6 million, respectively, as of September 30, 2024. At that date, neither DPL nor AES Ohio had short-term investments. DPL and AES Ohio had aggregate principal amounts of long-term debt outstanding of $1,852.3 million and $1,021.7 million, respectively.

From time to time, we may elect to repurchase our outstanding debt through cash purchases, privately negotiated transactions or otherwise when management believes such repurchases are favorable to make. The amounts involved in any such repurchases may be material.

We depend on timely and continued access to capital markets to manage our liquidity needs. The inability to raise capital on favorable terms, to refinance existing indebtedness or to fund operations and other commitments during times of political or economic uncertainty could have a material adverse effect on our results of operations, financial condition and cash flows. In addition, changes in the timing of tariff increases or delays in regulatory determinations could affect the cash flows and results of operations of our businesses.

During the nine months ended, DPL received $200.0 million in equity contributions from AES. DPL then made the same investments in AES Ohio. The proceeds from these equity contributions allow AES Ohio to seek to improve its infrastructure and modernize its grid while maintaining liquidity.

CASH FLOWS

DPL’s financial condition, liquidity and capital requirements include the consolidated results of its principal subsidiary AES Ohio. All material intercompany accounts and transactions have been eliminated in consolidation.

LIQUIDITY

We expect our existing cash balances, cash generated from operating activities and borrowing capacity on our existing credit facilities will be adequate to meet our anticipated operating needs, including interest expense on our debt and any dividends to our equity owners. Our business is capital intensive, requiring significant resources to fund operating expenses, construction expenditures, scheduled debt maturities and carrying costs, taxes and any dividend payments. For 2024 and subsequent years, we expect to satisfy these requirements with a combination of cash from operations, funds from debt financing and funds from equity capital contributions as our internal liquidity needs and market conditions warrant. We also expect that the borrowing capacity under the AES Ohio Credit Agreement will continue to be available to manage working capital requirements during those periods. The absence of adequate liquidity could adversely affect our ability to operate our business and have a material adverse effect on our results of operations, financial condition and cash flows.

58

At September 30, 2024, AES Ohio has access to the following revolving credit facility:

$ in millions	Type	Maturity	Commitment		Amounts available as of September 30, 2024
AES Ohio Credit Agreement	Revolving	December 2027	$	250.0	$	205.0

For the AES Ohio Credit Agreement, as of September 30, 2024, there were $45.0 million in borrowings under the facility, with the remaining $205.0 million available to AES Ohio. For more information on the AES Ohio Credit Agreement, see Note 5. Debt of our Form 10-K.

CAPITAL EXPENDITURE PROGRAM

Our capital expenditure program, including development and permitting costs, for the three-year period from 2024 through 2026 is currently estimated to cost up to $1.3 billion, and includes estimates as follows:

$ in millions	2024		2025		2026		For the three-year period from 2024 through 2026
Distribution-related additions, improvements and extensions	$	166.0	$	217.0	$	185.0	$	568.0

AES Ohio's projection includes expected spending under its Smart Grid Phase 1 included in the comprehensive settlement approved by the PUCO on June 16, 2021, as well as new transmission and distribution projects. AES Ohio’s spending programs are contingent on, among other events, successful regulatory outcomes in pending proceedings. See more information in Note 2. Regulatory Matters of DPL's Condensed Consolidated Financial Statements and AES Ohio's Condensed Financial Statements.

AES Ohio is subject to the mandatory reliability standards of NERC and ReliabilityFirst Corporation, one of the six NERC regions, of which AES Ohio is a member. Anticipated costs related to these standards are included in the overall capital projections above.

Debt Covenants

For information regarding our long-term debt covenants, see Note 6. Debt of our Form 10-K.

Credit Ratings

The following table presents, as of the filing of this report, the debt ratings and credit ratings (issuer/corporate rating) and outlook for DPL and AES Ohio.

Debt ratings	DPL Rating	DPL Outlook	AES Ohio Rating	AES Ohio Outlook
Fitch Ratings	BB (a)	Positive	BBB+ (b)	Stable
Moody's Investors Service, Inc.	Ba2 (a)	Positive	Baa1 (b)	Stable
Standard & Poor's Financial Services LLC	BB (a)	Positive	BBB (b)	Positive
Credit ratings	DPL Rating	DPL Outlook	AES Ohio Rating	AES Ohio Outlook
Fitch Ratings	BB	Positive	BBB-	Stable
Moody's Investors Service, Inc.	Ba2	Positive	Baa3	Stable
Standard & Poor's Financial Services LLC	BB	Positive	BB	Positive

(a) Rating relates to DPL's senior unsecured debt.

(b) Rating relates to AES Ohio’s senior secured debt.

We cannot predict whether the current debt and credit ratings of DPL or the debt and credit ratings of AES Ohio will remain in effect for any given period of time or that one or more of these ratings will not be lowered or withdrawn

59

entirely by a rating agency. A security rating is not a recommendation to buy, sell or hold securities. Such ratings may be subject to revision or withdrawal at any time by the assigning rating organization, and each rating should be evaluated independently of any other rating. If the rating agencies were to reduce our debt or credit ratings, our borrowing costs may increase, our potential pool of investors and funding resources may be reduced, and we may be required to post additional collateral under selected contracts. These events could have an adverse effect on our results of operations, financial condition and cash flows. In addition, any such reduction in our debt or credit ratings may adversely affect the trading price of our outstanding debt securities.

Off-Balance Sheet Arrangements

For information on guarantees, commercial commitments, and contractual obligations, see PART I, ITEM 1., Note 9. Commitments and Contingencies of DPL's Condensed Consolidated Financial Statements and PART I, ITEM 1., Note 8. Commitments and Contingencies of AES Ohio's Condensed Financial Statements.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

DPL’s Condensed Consolidated Financial Statements and AES Ohio’s Condensed Financial Statements are prepared in accordance with GAAP. In connection with the preparation of these financial statements, our management is required to make assumptions, estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses and the related disclosure of contingent liabilities. These assumptions, estimates and judgments are based on our historical experience and assumptions that we believe to be reasonable at the time. However, because future events and their effects cannot be determined with certainty, the determination of estimates requires the exercise of judgment. Our critical accounting estimates are those which require assumptions to be made about matters that are highly uncertain.

Different estimates could have a material effect on our financial results. Judgments and uncertainties affecting the application of these policies and estimates may result in materially different amounts being reported under different conditions or circumstances. Historically, however, recorded estimates have not differed materially from actual results. Significant items subject to such judgments include: the carrying value of property, plant and equipment; unbilled revenue; the valuation of insurance and claims liabilities; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; liabilities recorded for income tax exposures; litigation; contingencies; assets and liabilities related to employee benefits and intangible assets. Refer to our Form 10-K for the year ended December 31, 2023 for a complete listing of our critical accounting policies and estimates. We have reviewed and determined that these remain as critical accounting policies as of and for the nine months ended September 30, 2024.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes to our quantitative and qualitative disclosure about market risk as previously disclosed in our Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

DPL and AES Ohio, under the supervision and with the participation of its management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), evaluated the effectiveness of our “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of September 30, 2024, to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and include controls and procedures designed to ensure that information required to be disclosed by us in such reports is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosures.

Changes in Internal Controls over Financial Reporting

We periodically review our internal controls over financial reporting as part of our efforts to ensure compliance with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002. In addition, we routinely review our system of internal controls over financial reporting to identify potential changes to our processes and systems that may improve controls and increase efficiency, while ensuring that we maintain an effective internal controls environment. During the fiscal quarter ended September 30, 2024, we implemented SAP IS-U, a software solution that SAP

60

developed for businesses operating in the utility industries, which involved changes to related processes that are part of our system of internal controls over financial reporting and require testing for effectiveness.

Other than the system and related process changes described above, there were no changes in our internal control over financial reporting during the fiscal quarter ended September 30, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

61

PART II: OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In the normal course of business, we are subject to various lawsuits, actions, claims, and other proceedings. We are also, from time to time, involved in other reviews, investigations and proceedings by governmental and regulatory agencies regarding our business, certain of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. We have accrued in our Financial Statements for litigation and claims where it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We believe the amounts provided in our Financial Statements, as prescribed by GAAP, for these matters are adequate considering the probable and estimable contingencies. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various legal proceedings, claims and other matters (including those matters noted below), and to comply with applicable laws and regulations will not exceed the amounts reflected in our Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided for in our Financial Statements, cannot be reasonably determined, but could be material.

Our Form 10-K for the fiscal year ended December 31, 2023 and Forms 10-Q for the quarters ended March 31, and June 30, 2024, and the Notes to DPL’s Consolidated Financial Statements and AES Ohio’s Financial Statements included therein, contain descriptions of certain legal proceedings in which we are or were involved. The information in or incorporated by reference into this Item 1 to Part II is limited to certain recent developments concerning our legal proceedings and new legal proceedings, since the filing of such Forms 10-K and 10-Q, and should be read in conjunction with such Forms 10-K and 10-Q.

The following information is incorporated by reference into this Item: information about the legal proceedings contained in PART I, ITEM 2. – Management's Discussion and Analysis of Financial Condition and Results of Operations and PART I, ITEM 1., Note 2.

At the Closing, Buyer shall pay the Estimated Adjusted Purchase Price as set forth on the Estimated Seller’s Statement to Seller by wire transfer of immediately available funds to the account or accounts that Seller shall designate to Buyer prior to the Closing Date.

(c)    Adjustments to Base Purchase Price. The Base Purchase Price shall be adjusted as follows (the “Adjusted Purchase Price”):

(i)    the Base Purchase Price shall be increased by an amount of cash equal to fifteen percent (15%) of any Additional Capital Investment, together with interest thereon for the period from (and including) the applicable date or dates of the Additional Capital Investment to (but excluding) the Closing Date at a rate of eight percent (8%) per annum (any such aggregate interest amount, the “ACI Interest Amount”);

(iii)    the Base Purchase Price shall be increased by an amount of cash equal to the sum of (w) the Base Purchase Price multiplied by (x) eight percent (8%) divided by (y) three hundred sixty-six (366) multiplied by (z) the number of days elapsed during the period beginning on January 1, 2024 and ending on and including the Closing Date (such aggregate amount, the “Ticking Fee”);

provided that if the sum of (A) the ACI Interest Amount plus (B) the Ticking Fee minus (C) the Dividend Adjustment Amount is greater than Twenty-Two Million Four Hundred Ninety-Eight Thousand One Hundred Twenty-Five Dollars and Sixteen cents ($22,498,125.16), then the sum of such components shall be deemed to be Twenty-Two Million Four Hundred Ninety-Eight Thousand One Hundred Twenty-Five Dollars and Sixteen cents ($22,498,125.16) for purposes of the adjustments in this Section 2.1(c).

(d)    Estimated Seller’s Statement; Post-Closing Adjustment to Adjusted Purchase Price.

“Estimated Seller’s Statement”). Buyer shall have the right to review and comment on the Estimated Seller’s Statement prior to the Closing Date and Seller shall consider in good faith any reasonable comments proposed by the Buyer with respect to the Estimated Seller’s Statement prior to the Closing Date.

If Buyer has accepted the Seller’s Statement in writing or has not given written notice to Seller setting forth any objection of Buyer to the Seller’s Statement (a “Statement of Objections”) prior to the expiration of the Review Period, then the Seller’s Statement shall be final and binding upon the Parties. In the event that Buyer delivers a Statement of Objections during the Review Period, Seller and Buyer shall use their commercially reasonable efforts to agree on appropriate adjustments to the Seller’s Statement within thirty (30) days following the receipt by Seller of the Statement of Objections. If Seller and Buyer are unable to reach an agreement as to such amounts and adjustments within such 30-day period, then the matter shall be submitted as promptly as practicable to PricewaterhouseCoopers, or if PricewaterhouseCoopers is unwilling or unable to serve in such capacity, to such other independent accounting firm of national reputation agreed to by Buyer and Seller (such accountant, the “Settlement Accountant”), who shall resolve the matters still in dispute and adjust the Seller’s Statement to reflect such resolution and its determination of the Adjusted Purchase Price; provided, however, that the Settlement Accountant may not determine an Adjusted Purchase Price in excess of that claimed by Seller in the Seller’s Statement or less than that claimed by Buyer in the Statement of Objections.

In the event any dispute is submitted to the Settlement Accountant for resolution as provided in this Section 2.1(d)(ii), the fees, charges and expenses of the Settlement Accountant shall be paid one-half by Buyer and one-half by Seller. If Seller fails to timely deliver the Seller’s Statement in accordance with this Section 2.1(d)(ii)

18

within such thirty (30) day period, then the Estimated Seller’s Statement shall be deemed to be the Seller’s Statement.

(iii)    In the event that the Parties agree, or the Settlement Accountant determines, in accordance with Section 2.1(d)(ii) that the Adjusted Purchase Price should be decreased, then Seller shall pay, or cause to be paid, within five (5) Business Days following the determination of the final amounts pursuant to Section 2.1(d)(ii), to Buyer, by wire transfer of immediately available funds, an amount equal to such decrease in the Adjusted Purchase Price, together with interest thereon for the period from (and including) the Closing Date to (but excluding) the date of payment, at the Applicable Rate on the Closing Date.

If any amount payable under this Agreement is required by applicable Law to be deducted or withheld on account of any Tax, Buyer shall notify Seller no later than ten (10) Business Days prior to the due date for such payment and shall cooperate with Seller to reduce or eliminate any such deduction or withholding. To the extent any amounts are deducted and withheld in accordance with this Section 2.1(e) and paid to the relevant Tax authority, such amounts shall be treated for all purposes of this Agreement as having been paid to Seller.

(a)    In addition to Buyer’s rights under Section 10.1, Seller shall defend, indemnify and hold harmless Buyer Indemnified Parties from all Losses resulting from, relating to or arising out of any Generation Asset Environmental Liabilities.

(b)    In addition to Buyer’s rights under Section 10.1, Seller shall defend, indemnify and hold harmless Buyer Indemnified Parties from all Losses resulting from, relating to or arising out of any Generation Asset Retirement Obligations.

46

(c)    In addition to Buyer’s rights under Section 10.1, Seller shall defend, indemnify and hold harmless Buyer Indemnified Parties from all Losses resulting from, relating to or arising out of any of the Retained Actions or Proceedings. With respect to any claim for indemnification under this Section 10.4(c), the following shall apply:

(i)    Buyer Indemnified Parties shall not be entitled to indemnification with respect to any Loss with respect to the Retained Actions or Proceedings until the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order with respect to any of the Retained Actions or Proceedings are equal to or greater than Thirty Million Dollars ($30,000,000.00), and then only to the extent such Losses are in excess of such amount.

(ii)    Buyer’s or any other Buyer Indemnified Party’s Loss with respect to any applicable Retained Action or Proceeding for which an Order has been issued shall be determined as a yearly schedule over ten (10) years (horizon of the financial model) and calculated for each Order separately as the difference between (A) the Net Distribution pursuant to the Baseline Model for each applicable year minus (B) the Net Distribution reflected in an updated financial model for the same applicable year, which shall be determined by revising the Baseline Model solely to reflect the actual effects (positive and negative, including any mitigation with the respect thereto, which for the avoidance of doubt shall exclude any potential mitigation resulting from any appeal or rehearing of the Order) of the Order with respect to the applicable Retained Action or Proceeding, and containing the same assumption with respect to Net Debt to Capitalization for the latest year of the model as the one set forth in the latest year of the Baseline Model (the “Updated Model”) (provided that, if the amount referred to in clause (A) is equal to or less than the amount referred to in clause (B), then such difference shall be deemed to be equal to zero Dollars) (such difference with respect to any specific annual period, the “Annual Net Loss”).

(iii)    Notwithstanding Section 10.7, (A) in the event that the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to the Retained Actions or Proceedings are equal to or greater than One Hundred Thirty Million Dollars ($130,000,000.00) and less than Two Hundred Million Dollars ($200,000,000.00), Section 10.4(c)(v) shall apply, (B) in the event that the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to the Retained Actions or Proceedings are equal to or greater than Two Hundred Million Dollars ($200,000,000.00), Section 10.4(c)(vi) shall apply, and (C) in the event that the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to the Retained Actions or Proceedings are less than One Hundred Thirty Million Dollars ($130,000,000.00), within thirty (30) days after the receipt of a Claim Notice, Seller shall, working together with DP&L, prepare and deliver to Buyer a proposed Updated Model, a calculation of the Annual Net Loss for each applicable annual period as calculated pursuant to Section 10.4(c)(ii) (together with all supporting calculations), and the resulting ten (10) year schedule for these Annual Net Losses. Buyer shall have thirty (30) days after the receipt of Seller’s proposed Updated Model to review Seller’s proposed Updated Model and related computations. In connection with the review of

47

Seller’s proposed Updated Model, Seller shall give, and shall cooperate with Buyer to cause the Companies and Seller’s and the Companies’ Representatives to give, to Buyer and its Representatives reasonable access to the books, records and other materials of the Companies and the personnel of, and work papers prepared by or for, Seller, the Companies and their respective accountants and Representatives, including historical financial information relating to the Companies as Buyer or its Representatives may reasonably request, in each case, in order to permit the timely and complete review of Seller’s proposed Updated Model, including each of the components thereof. If Buyer has accepted Seller’s proposed Updated Model in writing or has not given written notice to Seller setting forth any objection of Buyer to Seller’s proposed Updated Model prior to the end of such thirty (30)-day period, then Seller’s proposed Updated Model and resulting ten (10) year Annual Net Loss schedule shall be final and binding upon the Parties. In the event that Buyer delivers written notice to Seller setting forth any objection of Buyer to Seller’s proposed Updated Model prior to the end of such thirty (30)-day period, Buyer and Seller shall attempt in good faith to reach an agreement with regard thereto within thirty (30) days of delivery of Buyer’s notice objecting to Seller’s proposed Updated Model. Upon a final determination of the Updated Model and Annual Net Loss schedule pursuant to Section 10.4(c)(iii) or Section 10.4(c)(iv), Seller shall pay to Buyer the Annual Net Loss for each applicable annual period in four equal installments on or about the date that Newco Inc. customarily issues dividends for each calendar quarter.

(iv)    If (a) Buyer and Seller cannot reach agreement within such 30-day period after delivery of Buyer’s notice objecting to Seller’s proposed Updated Model or (b) a matter is referred to this Section 10.4(c)(iv) following compliance with the procedures described in Section 10.4(c)(v) or Section 10.4(c)(vi), then the matter shall be submitted as promptly as practicable to a Qualified Valuation Arbiter selected jointly by Seller and Buyer, who shall serve as the Valuation Arbiter for all purposes hereunder to resolve the matters still in dispute and adjust the Updated Model to reflect such resolution; provided, however, that if Seller and Buyer are unable to agree on a mutually acceptable Qualified Valuation Arbiter, they shall each select a Qualified Valuation Arbiter (the costs and expenses of which shall be borne by the party selecting such Qualified Valuation Arbiter), and such Qualified Valuation Arbiters shall mutually select a third Qualified Valuation Arbiter to serve as the Valuation Arbiter, which Qualified Valuation Arbiter shall be the Valuation Arbiter for all purposes hereunder; provided, further, that, in any event, the Valuation Arbiter may not determine the Annual Net Loss to be in excess of that claimed by Buyer or less than that claimed by Seller. The Parties shall cause the Valuation Arbiter to make such determination within forty-five (45) days following the submission of the matter to the Valuation Arbiter for resolution, and such determination shall be final and binding upon Buyer and Seller and may be entered and enforced in any court having jurisdiction. Each of Buyer and Seller agrees that it shall not have any right to, and shall not, institute any Action or Proceeding of any kind challenging such determination or with respect to the matters that are the subject of this Section 10.4(c)(iv), except that the foregoing shall not preclude an Action or Proceeding to enforce such determination. In the event any dispute is submitted to the Valuation Arbiter for resolution as provided in this Section 10.4(c)(iv), the fees, charges and expenses of the Valuation Arbiter shall be paid one-half by Buyer and one-half by Seller.

48

(v)    In the event that the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to any of the Retained Actions or Proceedings are equal to or greater than One Hundred Thirty Million Dollars ($130,000,000.00) and less than Two Hundred Million Dollars ($200,000,000.00), Buyer and Seller shall negotiate in good faith and use commercially reasonable efforts to determine and agree to the amount of Losses to the Buyer Indemnified Parties resulting from such Order, including identifying and determining any Losses to the Buyer Indemnified Parties that exceed the ten (10) year horizon of the Updated Model; provided that, if Buyer and Seller cannot reach agreement on such amount within thirty (30) days after the date of such Order, then Buyer and Seller shall escalate the matter to, with respect to Buyer, its executive vice president, and, with respect to Seller, its chief executive officer, in each case, of their respective ultimate parent entities for negotiation; provided, further, that if the foregoing persons cannot reach agreement on such amount within thirty (30) days of the referral thereto, the matter shall be referred to a Qualified Valuation Arbiter selected in the manner set forth in Section 10.4(c)(iv), who shall determine the Losses to the Buyer Indemnified Parties resulting from such Order in accordance with the procedures and terms of Section 10.4(c)(iv), which Losses shall be paid quarterly in the manner contemplated by Section 10.4(c)(iii).

(vi)     In the event that the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to any of the Retained Actions or Proceedings are equal to or greater than Two Hundred Million Dollars ($200,000,000.00), Buyer and Seller shall negotiate in good faith and use commercially reasonable efforts to determine and agree to the amount of Losses to the Buyer Indemnified Parties resulting from such Order, including identifying and determining any Losses to the Buyer Indemnified Parties that exceed the ten (10) year horizon of the Updated Model; provided that, if Buyer and Seller cannot reach agreement on such amount within thirty (30) days after the date of such Order, then Buyer and Seller shall escalate the matter to, with respect to Buyer, its executive vice president, and, with respect to Seller, its chief executive officer, in each case, of their respective ultimate parent entities for negotiation; provided, further, that if the foregoing persons cannot reach agreement on such amount within thirty (30) days of the referral thereto, the matter shall be referred to a Qualified Valuation Arbiter selected in the manner set forth in Section 10.4(c)(iv), who shall determine the Losses to the Buyer Indemnified Parties resulting from such Order in accordance with the procedures and terms of Section 10.4(c)(iv), which Losses shall be paid quarterly in the manner contemplated by Section 10.4(c)(iii); provided, further, that, unless the Parties otherwise agree (in each Party’s sole discretion), the conclusion of the foregoing process shall constitute a Put Triggering Event (as defined in the Newco Shareholder Agreement) under Section 2.15(a)(iii) of the Newco Shareholders Agreement, and Buyer shall have a Put Right (as defined in the Newco Shareholder Agreement) exercisable by the delivery of a Put Exercise Notice (as defined in the Newco Shareholders Agreement) pursuant to Section 2.15(c) of the Newco Shareholders Agreement. The exercise of the Put Right shall be in accordance with the terms and procedures set forth in the Newco Shareholders Agreement, and the terms of Section 2.15 of the Newco Shareholders Agreement are incorporated herein mutatis mutandis. For the avoidance of doubt, for purposes of determining the Put Price (as such term is defined in the Newco Shareholders Agreement) under Section

49

2.15(d) of the Newco Shareholders Agreement, the fair market value of the Put Shares shall be calculated without taking into account the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to any of the Retained Actions or Proceedings.

(d)    In addition to Buyer’s rights under Section 10.1, Seller shall defend, indemnify and hold harmless Buyer Indemnified Parties from all Losses resulting from, relating to or arising out of the Pre-Closing Reorganization.

(e)    Except as provided in Section 10.4(c), any indemnification payment required to be made pursuant to this Section 10.4 shall be made in accordance with Section 10.7 or Section 10.8, as applicable. Notwithstanding anything to the contrary in this Agreement, (x) to the extent that any of the Companies recovers any Losses resulting from, relating to or arising out of any Generation Asset Retirement Obligations, Generation Asset Environmental Liabilities or Retained Actions or Proceedings from customers or third parties for which Buyer was indemnified by Seller pursuant to Section 10.4(a), Section 10.4(b) or Section 10.4(c) or (y) in the event that the Losses to any Buyer Indemnified Party with respect to any Retained Actions or Proceedings are reduced in a Final Order as a result of any appeal or rehearing of the Order giving rise to any payments under Section 10.4(c), Seller shall, working together with DP&L, prepare and deliver to Buyer a revised proposed Updated Model, and the Parties shall recalculate the Annual Net Loss schedule in accordance with the procedures set forth in Section 10.4(c) to account for the recovery or reduction, as applicable, of any such Losses contemplated by this Section 10.4(e) as an adjustment to all future Annual Net Losses, including by decreasing such future payments by the amount of such excess indemnification payments; provided, that, to the extent such decrease in future payments is not sufficient to adjust for all excess indemnification payments, Seller shall have the right to cause DP&L to offset all future dividends distributable to Buyer by the amount of such excess indemnification payments (together with interest thereon at a rate of eight percent (8%) per annum) until such time as the amount of such dividends that would have otherwise been distributable to Buyer is equal to the amount of such excess (provided that, in lieu of such offset of future dividends, Buyer may elect to pay Seller the aggregate remaining amount of such offset, which amount shall not include any future interest); provided, further, that in no event shall the remedies in this Section 10.4(e) reduce the dividends or distributions actually received by Buyer in any quarterly period to an amount that is less than the amount required to service debt under any agreement entered into by Buyer or its Affiliates for third-party debt financing in connection with Buyer’s investment in Newco Inc. For the avoidance of doubt, and notwithstanding anything to the contrary herein, Seller’s sole remedy with respect to any excess indemnification payments contemplated by this Section 10.4(e) shall be as set forth in this Section 10.4(e).

(f)    Except in the case of fraud, Seller’s liability under this Section 10.4 shall be limited to the Adjusted Purchase Price.

Section 10.5    Indemnification for Pre-Closing Taxes. In addition to Buyer’s rights under Section 10.1, without duplication, Seller shall defend, indemnify and hold harmless

50

Buyer Indemnified Parties from all Losses resulting from any (a) Pre-Closing Tax Sharing Payments, (b) Taxes imposed on any of the Companies after January 1, 2024, with respect to a taxable period ending on or prior to December 31, 2023, and (c) Taxes imposed on any of the Companies after January 1, 2024, in respect of income of any member (other than the Companies) of an affiliated, consolidated, combined or unitary group of which any of the Companies (or any predecessor) is or was a member on or prior to the Closing Date, including pursuant to Treasury Regulations Section 1.1502-6 or any analogous or similar state or local Law with respect to any Tax period ending on or before the Closing Date; provided, however, that Seller shall not be required to defend, indemnify or hold harmless Buyer Indemnified Parties under this Section 10.5 for any Losses resulting from or attributable to liabilities for Taxes of the Companies reflected on the Reference Balance Sheet. Notwithstanding anything to the contrary contained herein, to the extent that a Company or any of its Affiliates receives any refund (or credit in lieu of a refund) of Taxes of the Companies that are reflected as a liability on the Reference Balance Sheet or for which a Buyer Indemnified Party is entitled to an indemnity under Section 10.5(b) or it is determined based on the filing of an applicable Tax Return that there was an over-accrual of Taxes reflected on the Reference Balance Sheet (such refund, credit and/or over-accrual, a “Tax Refund”), the amount of such Tax Refund (including any interest received from the applicable Governmental Authority, and reduced by any reasonable costs or expenses (including Taxes) incurred in connection with receiving such refunds or credits) that, in any case, increases the value of the Acquired Newco Shares based on the underlying increase in the value of the Companies (for the avoidance of doubt, taking into account the percentage of ownership of Newco Inc. of such owner) (such increases, “Buyer’s Proportionate Share”) shall offset and therefore reduce (on a dollar-for-dollar basis) the amount of any indemnity payment otherwise due to Buyer under this Article X. If Seller has a current obligation to make an indemnity payment under this Article X, Seller shall make such payment in accordance with this Article X without any delays due to an expected or pending Tax Refund. If Seller has already made an indemnity payment under this Article X prior to the Company or any of its Affiliates receiving a Tax Refund, and a Tax Refund is subsequently received by the Company or any of its Affiliates, Seller shall notify Buyer of the receipt of such Tax Refund and, within ten (10) Business Days of Buyer’s receipt of such notice, Buyer shall pay to Seller an amount equal to the lesser of (i) Buyer’s Proportionate Share of such Tax Refund amount or (ii) the amount of indemnity already paid to Buyer under this Article X. If Buyer’s Proportionate Share of such Tax Refund received by the Company or any of its Affiliates exceeds the amount of the indemnity already paid to Buyer under this Article X (an “Excess Tax Refund Amount”), the Excess Tax Refund Amount shall offset and reduce any future subsequent indemnity payments to be made by Seller under this Article X.

Section 10.6    Adjustments for Indemnity Payments. Except as otherwise required by Law, the Parties shall treat for all Tax purposes any indemnification payment made hereunder as an adjustment to the Adjusted Purchase Price.

Section 10.7    Procedure for Indemnification with Respect to Direct Claims. Whenever any direct claim shall arise for indemnification under this Article X (other than Section 10.4(c)), the Indemnified Party, after attaining knowledge of such claim, shall promptly

51

notify the Indemnitor of the claim and, when known, the facts constituting the basis for such claim (such notice, a “Claim Notice”). If within thirty (30) days after receiving a Claim Notice the Indemnitor does not give written notice to the Indemnified Party that it contests such Claim Notice, then the amount of indemnity payable for such claim shall be as set forth in the Indemnified Party’s Claim Notice. If the Indemnitor contests such indemnity, the Parties shall attempt in good faith to reach an agreement with regard thereto within thirty (30) days of delivery of the Indemnitor’s notice objecting to the claim. If the Parties cannot reach agreement within such 30-day period, the matter shall be resolved in accordance with the provisions of Section 11.8.

Section 10.8    Procedure for Indemnification with Respect to Third-Party Claims.

(a)    Notice of Claim. If any legal proceedings shall be instituted or any claim or demand shall be asserted by any third party in respect of which indemnification may be sought by any Indemnified Party under this Article X, such Indemnified Party shall, within ten (10) days of the actual receipt by a responsible officer of notice of the institution of such legal proceeding or such claim or demand, submit a Claim Notice to the Indemnitor, specifying the nature of such legal proceedings, claim or demand and the amount or the estimated amount thereof to the extent then determinable, which estimate shall not be binding upon the Indemnified Party; provided, that the failure of an Indemnified Party to give timely notice shall not affect its rights to indemnification under this Article X, except to the extent that the Indemnitor has been actually prejudiced by such failure.

(b)    Conduct of Claim.

(i)    Except with respect to Taxes:

(A)    The Indemnitor shall have the right, at its option and at its own expense, to be represented by counsel of its choice and to participate in, or take control of, the defense, negotiation and/or settlement of any proceeding, claim or demand that relates to any amounts indemnifiable or potentially indemnifiable under this Article X, provided, that the Indemnified Party may participate in any such proceeding with counsel of its choice (which shall be at its own expense). The Indemnified Party shall have a right to notice of any settlement, and the Indemnitor shall not compromise or settle any claim, nor execute or otherwise agree to any consent decree, that (I) provides for other than monetary payment without the Indemnified Party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed or (II) does not include as an unconditional term thereof the giving of a release from all liability with respect to such claim by each claimant or plaintiff to each Indemnified Party that is or may be subject to the third-party claim, without the Indemnified Party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

(B)    If the Indemnitor elects not to defend or settle such proceeding, claim or demand, the Indemnified Party shall provide fifteen (15) days advance written notice of any proposed settlement or compromise to the Indemnitor and shall act

52

reasonably and in accordance with the Indemnified Party’s good faith business judgment. Without the consent of the Indemnitor (not to be unreasonably withheld, conditioned or delayed), no Indemnified Party shall settle or compromise any claim for which it asserts a right to indemnification, nor execute or agree to any consent decree with respect to any such claim, unless (I) the terms of such settlement are substantially the same as the proposed settlement or compromise delivered in the written notice to the Indemnitor or (II) such settlement (x) provides only for the payment of money and does not include any admission of guilt or culpability and (y) includes a full release from all liability with respect to such claim by each claimant or plaintiff to each Indemnitor that is or may be subject to the third-party claim.

(C)    The Indemnitor and the Indemnified Party shall cooperate fully with each other in connection with the defense, negotiation or settlement of any such legal proceeding, claim or demand.

(ii)    Notwithstanding anything to the contrary in this Agreement, DPL and AES shall each have the right, at its option and at its own expense, to be represented by counsel of its choice and to participate in, or take control of, the defense, negotiation or settlement of any proceeding, claim or demand that relates to Taxes of Seller or any of its Affiliates (including Newco Inc. and DP&L).

(c)    Payment of Third-Party Claims. After final non-appealable judgment or award shall have been rendered by a court, arbitration board or administrative agency of competent jurisdiction, or a settlement shall have been consummated, or the Indemnified Party and the Indemnitor shall have arrived at a mutually binding agreement with respect to each separate matter indemnified by the Indemnitor, the Indemnified Party shall forward to the Indemnitor notice of any sums due and owing by the Indemnitor with respect to such matter, and such amount shall be paid within five (5) Business Days by the Indemnitor to the applicable Indemnified Party.

(d)    Access to Information. If any claim is made by a third party against an Indemnified Party, the Indemnified Party shall use commercially reasonable efforts to make available to the Indemnitor those partners, members, officers and employees whose assistance, testimony or presence is necessary to assist the Indemnitor in evaluating and in defending such claims; provided, that any such access shall be conducted in such a manner as not to interfere unreasonably with the operations of the business of the Indemnified Party.

Section 10.9    Subrogation. Except with respect to Taxes, upon payment of a Loss by an Indemnitor to an Indemnified Party pursuant to this Article X, such Indemnitor, without any further action, shall be subrogated to any and all claims that such Indemnified Party or any member of its Indemnified Group may have against third parties relating to such Loss, but only to the extent of the amount paid to such Indemnified Party or any member of its Indemnified Group by such Indemnitor in respect of such Loss, and such Indemnified Party and the members of its Indemnified Group shall use commercially reasonable efforts to cooperate

53

with such Indemnitor, at the expense of such Indemnitor, in order to enable such Indemnitor to pursue such claims.

Section 10.10    Exclusive Remedy. Notwithstanding anything to the contrary which may be contained herein, the indemnities set forth in this Article X shall become effective as of the Closing Date. Other than equitable remedies, the indemnities set forth in this Article X, absent intentional misconduct, intentional or willful misrepresentation or fraud, shall be the exclusive remedies of Buyer and Seller and their respective Indemnified Groups due to the breach or inaccuracy of any representation or warranty, or the breach or default of any covenant or agreement, contained in this Agreement, and the Parties shall not be entitled to a rescission of this Agreement or to any further indemnification rights, breach or damages or claims of any nature whatsoever in respect thereof, all of which the Parties hereby waive.

Section 10.11    Damages Disallowed. Except as expressly provided herein, no Party or its Affiliates, or other members of its Indemnified Group, shall be liable hereunder at any time for consequential, exemplary, indirect, special or punitive loss of the other Party or any of the members of their respective Indemnified Groups, whether in contract, tort (including negligence), strict liability or otherwise.

Section 10.12    Certain Tax Benefits. Each Party shall pay to the other Party the amount of any reduction in cash Tax liability of the first Party derived directly from any Loss for which the other Party has indemnified the first Party or any member of its Indemnified Group pursuant to this Article X, but only to the extent such reduction in cash Tax liability occurs in the taxable period during which such Loss is sustained or in the immediately following taxable period. The amount of any reduction in cash Tax liability shall be calculated on a “with and without” basis, taking into account any Taxes imposed on any payments received from the other Party under this Agreement and all other relevant facts, including the first Party’s other Tax attributes.

Section 11.3    Severability. Any term or provision of this Agreement that is determined by a court of competent jurisdiction to be invalid or unenforceable for any reason shall, as to that jurisdiction, be ineffective solely to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is determined by a court of competent jurisdiction to be so broad as to be unenforceable, that provision shall be interpreted to be only so broad as is enforceable.

Section 11.4    Assignment; Third-Party Beneficiaries. Except as otherwise provided herein, all the terms and provisions of this Agreement and the other Transaction Documents shall be binding upon, shall inure to the benefit of and shall be enforceable by the Parties and their respective successors and permitted assigns. Neither this Agreement, nor any other Transaction Document, nor any right hereunder or thereunder, may be assigned by any Party without the prior written consent of the other Party; provided, however, that Seller acknowledges that Buyer may enter into a “back-to-back” arrangement with a subsequent purchaser of Acquired Newco Shares that is an Affiliate of Buyer and any Loss suffered or incurred by any such subsequent purchaser shall be deemed a Loss suffered or incurred by Buyer for purposes of this Agreement (to the extent such Loss would have been a Loss suffered or incurred by Buyer if Buyer was the owner of the Acquired Newco Shares). This Agreement is not intended to confer any rights or remedies hereunder upon any other Person except the Parties, it being for the exclusive benefit of the Parties and their respective successors and permitted assigns. Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the Agreement Date or as of any other date.

Section 11.5    Amendments. This Agreement may be amended, modified or supplemented, with respect to any of the terms contained in this Agreement, only by written agreement (referring specifically to this Agreement) signed by or on behalf of both Parties.

Section 11.6    Waiver. No waiver of any breach of any of the terms of this Agreement shall be effective unless such waiver is made expressly in an instrument in writing specifically referring to this Agreement and executed and delivered by the Party against whom such waiver is claimed. No waiver of any breach shall be deemed to be a further or continuing waiver of such breach or a waiver of any other or subsequent breach. Except as otherwise expressly provided herein, no failure on the part of any Party to exercise, and no delay in exercising, any right, power or remedy hereunder, or otherwise available in respect hereof at law or in equity, shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof, or the exercise of any other right, power or remedy. The rights and remedies of the Parties are cumulative and are in addition to, and not in substitution for, any other rights and remedies available at law or in equity or otherwise.

Section 11.7    Interpretation.

56

(a)    When a reference is made in this Agreement to an Article, Section, clause or Exhibit, such reference shall be to an Article, Section or clause of, or Exhibit to, this Agreement unless otherwise indicated, and the words “Agreement,” “hereby,” “herein,” “hereof,” “hereunder” and words of similar import refer to this Agreement as a whole (including any Exhibits) and not merely to the specific section, paragraph or clause in which such word appears and “paragraphs” or “clauses” shall be deemed references to separate paragraphs or clauses of the Section in which the reference occurs. The table of contents and the Article and Section headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the Parties and do not in any way affect the meaning or interpretation of this Agreement. The phrases “the date of this Agreement,” “the date hereof” and terms of similar import, shall be deemed to refer to the Agreement Date. References to any statute are to that statute, as amended from time to time, and to the rules and regulations promulgated thereunder. Unless otherwise expressly provided herein, references to any agreement or document shall be a reference to such agreement or document as amended, modified or supplemented and in effect from time to time and shall include reference to all exhibits, schedules and other documents or agreements attached thereto or incorporated therein, including waivers or consents. Unless otherwise expressly provided herein, references to any Person include the successors and permitted assigns of that Person. Whenever the content of this Agreement permits, the masculine gender shall include the feminine and neuter genders, and a reference to singular or plural shall be interchangeable with the other. References from or through any date mean, unless otherwise specified, from and including or through and including, respectively. Where this Agreement states that a Party “shall,” “will” or “must” perform in some manner or otherwise act or omit to act, it means that such Party is legally obligated to do so in accordance with this Agreement. As used in this Agreement: (i) the term “including” and words of similar import mean “including, without limitation” unless otherwise specified, (ii) “$” and “dollars” refer to the currency of the United States of America, (iii) “or” shall include both the conjunctive and disjunctive and (iv) “any” shall mean “one or more”. Unless the defined term “Business Days” is used, references to “days” in this Agreement refer to calendar days.

If Buyer has accepted the Seller’s Statement in writing or has not given written notice to Seller setting forth any objection of Buyer to the Seller’s Statement (a “Statement of Objections”) prior to the expiration of the Review Period, then the Seller’s Statement shall be final and binding upon the Parties. In the event that Buyer delivers a Statement of Objections during the Review Period, Seller and Buyer shall use their commercially reasonable efforts to agree on appropriate adjustments to the Seller’s Statement within thirty (30) days following the receipt by Seller of the Statement of Objections.

Notwithstanding anything to the contrary contained in this Article X, except as otherwise provided in Section 10.4, with respect to any claim for indemnification arising under this Agreement for which the Companies are required to pay any amount in satisfaction of such claim, Seller, as the Indemnitor, shall indemnify and hold harmless Buyer or any Buyer Indemnified Party for its Applicable Percentage of such claim.

Section 10.3    Limitations on Indemnification.

(a)    With respect to any claim for indemnification arising from any breach or inaccuracy of any representations and warranties other than Fundamental Representations, each Party’s liability under Section 10.1 shall be limited to an amount equal to ten percent (10%) of the Adjusted Purchase Price. As to any claim for indemnification for a breach or inaccuracy of any Fundamental Representation, each Party’s liability under this Article X shall be limited to the Adjusted Purchase Price.

(b)    With respect to any claim for indemnification arising from any breach or inaccuracy of any representations and warranties other than Fundamental Representations, the Indemnified Party shall not be entitled to indemnification with respect to any Loss unless and until such Indemnified Party’s Indemnified Group has incurred, sustained or become subject to Losses in excess of in the aggregate one-half percent (0.5%) of the Base Purchase Price, and then only to the extent such Losses are in excess of $500,000.

(c)    The limitations set forth in this Section 10.3 shall not apply to claims by Buyer under Section 10.4 or Section 10.5, or to claims of, or causes of action arising from, intentional misconduct, intentional or willful misrepresentation or fraud by any Party.

(c)    In addition to Buyer’s rights under Section 10.1, Seller shall defend, indemnify and hold harmless Buyer Indemnified Parties from all Losses resulting from, relating to or arising out of any of the Retained Actions or Proceedings. With respect to any claim for indemnification under this Section 10.4(c), the following shall apply:

44

(i)    Buyer Indemnified Parties shall not be entitled to indemnification with respect to any Loss with respect to the Retained Actions or Proceedings until the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order with respect to any of the Retained Actions or Proceedings are equal to or greater than Thirty Million Dollars ($30,000,000.00), and then only to the extent such Losses are in excess of such amount.

(ii)    Buyer’s or any other Buyer Indemnified Party’s Loss with respect to any applicable Retained Action or Proceeding for which an Order has been issued shall be determined as a yearly schedule over ten (10) years (horizon of the financial model) and calculated for each Order separately as the difference between (A) the Net Distribution pursuant to the Baseline Model for each applicable year minus (B) the Net Distribution reflected in an updated financial model for the same applicable year, which shall be determined by revising the Baseline Model solely to reflect the actual effects (positive and negative, including any mitigation with the respect thereto, which for the avoidance of doubt shall exclude any potential mitigation resulting from any appeal or rehearing of the Order) of the Order with respect to the applicable Retained Action or Proceeding, and containing the same assumption with respect to Net Debt to Capitalization for the latest year of the model as the one set forth in the latest year of the Baseline Model (the “Updated Model”) (provided that, if the amount referred to in clause (A) is equal to or less than the amount referred to in clause (B), then such difference shall be deemed to be equal to zero Dollars) (such difference with respect to any specific annual period, the “Annual Net Loss”).

(iii)    Notwithstanding Section 10.7, (A) in the event that the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to the Retained Actions or Proceedings are equal to or greater than One Hundred Thirty Million Dollars ($130,000,000.00) and less than Two Hundred Million Dollars ($200,000,000.00), Section 10.4(c)(v) shall apply, (B) in the event that the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to the Retained Actions or Proceedings are equal to or greater than Two Hundred Million Dollars ($200,000,000.00), Section 10.4(c)(vi) shall apply, and (C) in the event that the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to the Retained Actions or Proceedings are less than One Hundred Thirty Million Dollars ($130,000,000.00), within thirty (30) days after the receipt of a Claim Notice, Seller shall, working together with DP&L, prepare and deliver to Buyer a proposed Updated Model, a calculation of the Annual Net Loss for each applicable annual period as calculated pursuant to Section 10.4(c)(ii) (together with all supporting calculations), and the resulting ten (10) year schedule for these Annual Net Losses. Buyer shall have thirty (30) days after the receipt of Seller’s proposed Updated Model to review Seller’s proposed Updated Model and related computations. In connection with the review of Seller’s proposed Updated Model, Seller shall give, and shall cooperate with Buyer to cause the Companies and Seller’s and the Companies’ Representatives to give, to Buyer and its Representatives reasonable access to the books, records and other materials of the Companies and the personnel of, and work papers prepared by or for, Seller, the Companies and their respective accountants and Representatives, including historical financial information relating to the Companies as Buyer or its Representatives may reasonably request, in each case, in order to permit the timely and complete review of Seller’s proposed Updated Model, including each of

45

the components thereof. If Buyer has accepted Seller’s proposed Updated Model in writing or has not given written notice to Seller setting forth any objection of Buyer to Seller’s proposed Updated Model prior to the end of such thirty (30)-day period, then Seller’s proposed Updated Model and resulting ten (10) year Annual Net Loss schedule shall be final and binding upon the Parties. In the event that Buyer delivers written notice to Seller setting forth any objection of Buyer to Seller’s proposed Updated Model prior to the end of such thirty (30)-day period, Buyer and Seller shall attempt in good faith to reach an agreement with regard thereto within thirty (30) days of delivery of Buyer’s notice objecting to Seller’s proposed Updated Model. Upon a final determination of the Updated Model and Annual Net Loss schedule pursuant to Section 10.4(c)(iii) or Section 10.4(c)(iv), Seller shall pay to Buyer the Annual Net Loss for each applicable annual period in four equal installments on or about the date that Newco II Inc. customarily issues dividends for each calendar quarter.

(iv)    If (a) Buyer and Seller cannot reach agreement within such 30-day period after delivery of Buyer’s notice objecting to Seller’s proposed Updated Model or (b) a matter is referred to this Section 10.4(c)(iv) following compliance with the procedures described in Section 10.4(c)(v) or Section 10.4(c)(vi), then the matter shall be submitted as promptly as practicable to a Qualified Valuation Arbiter selected jointly by Seller and Buyer, who shall serve as the Valuation Arbiter for all purposes hereunder to resolve the matters still in dispute and adjust the Updated Model to reflect such resolution; provided, however, that if Seller and Buyer are unable to agree on a mutually acceptable Qualified Valuation Arbiter, they shall each select a Qualified Valuation Arbiter (the costs and expenses of which shall be borne by the party selecting such Qualified Valuation Arbiter), and such Qualified Valuation Arbiters shall mutually select a third Qualified Valuation Arbiter to serve as the Valuation Arbiter, which Qualified Valuation Arbiter shall be the Valuation Arbiter for all purposes hereunder; provided, further, that, in any event, the Valuation Arbiter may not determine the Annual Net Loss to be in excess of that claimed by Buyer or less than that claimed by Seller. The Parties shall cause the Valuation Arbiter to make such determination within forty-five (45) days following the submission of the matter to the Valuation Arbiter for resolution, and such determination shall be final and binding upon Buyer and Seller and may be entered and enforced in any court having jurisdiction. Each of Buyer and Seller agrees that it shall not have any right to, and shall not, institute any Action or Proceeding of any kind challenging such determination or with respect to the matters that are the subject of this Section 10.4(c)(iv), except that the foregoing shall not preclude an Action or Proceeding to enforce such determination. In the event any dispute is submitted to the Valuation Arbiter for resolution as provided in this Section 10.4(c)(iv), the fees, charges and expenses of the Valuation Arbiter shall be paid one-half by Buyer and one-half by Seller.

(v)    In the event that the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to any of the Retained Actions or Proceedings are equal to or greater than One Hundred Thirty Million Dollars ($130,000,000.00) and less than Two Hundred Million Dollars ($200,000,000.00), Buyer and Seller shall negotiate in good faith and use commercially reasonable efforts to determine and agree to the amount of Losses to the Buyer Indemnified Parties resulting from such Order, including identifying and determining any Losses to the Buyer Indemnified Parties that exceed the ten (10) year horizon of the Updated Model; provided that, if

46

Buyer and Seller cannot reach agreement on such amount within thirty (30) days after the date of such Order, then Buyer and Seller shall escalate the matter to, with respect to Buyer, its executive vice president, and, with respect to Seller, its chief executive officer, in each case, of their respective ultimate parent entities for negotiation; provided, further, that if the foregoing persons cannot reach agreement on such amount within thirty (30) days of the referral thereto, the matter shall be referred to a Qualified Valuation Arbiter selected in the manner set forth in Section 10.4(c)(iv), who shall determine the Losses to the Buyer Indemnified Parties resulting from such Order in accordance with the procedures and terms of Section 10.4(c)(iv), which Losses shall be paid quarterly in the manner contemplated by Section 10.4(c)(iii).

(vi)    In the event that the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to any of the Retained Actions or Proceedings are equal to or greater than Two Hundred Million Dollars ($200,000,000.00), Buyer and Seller shall negotiate in good faith and use commercially reasonable efforts to determine and agree to the amount of Losses to the Buyer Indemnified Parties resulting from such Order, including identifying and determining any Losses to the Buyer Indemnified Parties that exceed the ten (10) year horizon of the Updated Model; provided that, if Buyer and Seller cannot reach agreement on such amount within thirty (30) days after the date of such Order, then Buyer and Seller shall escalate the matter to, with respect to Buyer, its executive vice president, and, with respect to Seller, its chief executive officer, in each case, of their respective ultimate parent entities for negotiation; provided, further, that if the foregoing persons cannot reach agreement on such amount within thirty (30) days of the referral thereto, the matter shall be referred to a Qualified Valuation Arbiter selected in the manner set forth in Section 10.4(c)(iv), who shall determine the Losses to the Buyer Indemnified Parties resulting from such Order in accordance with the procedures and terms of Section 10.4(c)(iv), which Losses shall be paid quarterly in the manner contemplated by Section 10.4(c)(iii); provided, further, that, unless the Parties otherwise agree (in each Party’s sole discretion), the conclusion of the foregoing process shall constitute a Put Triggering Event (as defined in the Newco II Shareholders Agreement) under Section 2.15(a)(iii) of the Newco II Shareholders Agreement, and Buyer shall have a Put Right (as defined in the Newco II Shareholders Agreement) exercisable by the delivery of a Put Exercise Notice (as defined in the Newco II Shareholders Agreement) pursuant to Section 2.15(c) of the Newco II Shareholders Agreement. The exercise of the Put Right shall be in accordance with the terms and procedures set forth in the Newco II Shareholders Agreement, and the terms of Section 2.15 of the Newco II Shareholders Agreement are incorporated herein mutatis mutandis.For the avoidance of doubt, for purposes of determining the Put Price (as such term is defined in the Newco II Shareholders Agreement) under Section 2.15(d) of the Newco II Shareholders Agreement, the fair market value of the Put Shares shall be calculated without taking into account the aggregate Losses suffered or incurred by the Companies resulting from or arising out of any Order or combination of Orders with respect to any of the Retained Actions or Proceedings.

(d)    In addition to Buyer’s rights under Section 10.1, Seller shall defend, indemnify and hold harmless Buyer Indemnified Parties from all Losses resulting from, relating to or arising out of the Pre-Closing Reorganization.

47

(e)    Except as provided in Section 10.4(c), any indemnification payment required to be made pursuant to this Section 10.4 shall be made in accordance with Section 10.7 or Section 10.8, as applicable. Notwithstanding anything to the contrary in this Agreement, (x) to the extent that any of the Companies recovers any Losses resulting from, relating to or arising out of any Generation Asset Retirement Obligations, Generation Asset Environmental Liabilities or Retained Actions or Proceedings from customers or third parties for which Buyer was indemnified by Seller pursuant to Section 10.4(a), Section 10.4(b) or Section 10.4(c) or (y) in the event that the Losses to any Buyer Indemnified Party with respect to any Retained Actions or Proceedings are reduced in a Final Order as a result of any appeal or rehearing of the Order giving rise to any payments under Section 10.4(c), Seller shall, working together with DP&L, prepare and deliver to Buyer a revised proposed Updated Model, and the Parties shall recalculate the Annual Net Loss schedule in accordance with the procedures set forth in Section 10.4(c) to account for the recovery or reduction, as applicable, of any such Losses contemplated by this Section 10.4(e) as an adjustment to all future Annual Net Losses, including by decreasing such future payments by the amount of such excess indemnification payments; provided, that, to the extent such decrease in future payments is not sufficient to adjust for all excess indemnification payments, Seller shall have the right to cause DP&L to offset all future dividends distributable to Buyer by the amount of such excess indemnification payments (together with interest thereon at a rate of eight percent (8%) per annum) until such time as the amount of such dividends that would have otherwise been distributable to Buyer is equal to the amount of such excess (provided that, in lieu of such offset of future dividends, Buyer may elect to pay Seller the aggregate remaining amount of such offset, which amount shall not include any future interest); provided, further, that in no event shall the remedies in this Section 10.4(e) reduce the dividends or distributions actually received by Buyer in any quarterly period to an amount that is less than the amount required to service debt under any agreement entered into by Buyer or its Affiliates for third-party debt financing in connection with Buyer’s investment in Newco II Inc. For the avoidance of doubt, and notwithstanding anything to the contrary herein, Seller’s sole remedy with respect to any excess indemnification payments contemplated by this Section 10.4(e) shall be as set forth in this Section 10.4(e).

(f)    Except in the case of fraud, Seller’s liability under this Section 10.4 shall be limited to the Adjusted Purchase Price.

Section 10.5    Indemnification for Pre-Closing Taxes. In addition to Buyer’s rights under Section 10.1, without duplication, Seller shall defend, indemnify and hold harmless Buyer Indemnified Parties from all Losses resulting from any (a) Pre-Closing Tax Sharing Payments, (b) Taxes imposed on any of the Companies after January 1, 2024, with respect to a taxable period ending on or prior to December 31, 2023, and (c) Taxes imposed on any of the Companies after January 1, 2024, in respect of income of any member (other than the Companies) of an affiliated, consolidated, combined or unitary group of which any of the Companies (or any predecessor) is or was a member on or prior to the Closing Date, including pursuant to Treasury Regulations Section 1.1502-6 or any analogous or similar state or local Law with respect to any Tax period ending on or before the Closing Date; provided, however, that Seller shall not be required to defend, indemnify or hold harmless Buyer Indemnified Parties under this Section 10.5 for any Losses resulting from or attributable to liabilities for Taxes of the Companies reflected on the Reference Balance Sheet. Notwithstanding anything to the contrary

48

contained herein, to the extent that a Company or any of its Affiliates receives any refund (or credit in lieu of a refund) of Taxes of the Companies that are reflected as a liability on the Reference Balance Sheet or for which a Buyer Indemnified Party is entitled to an indemnity under Section 10.5(b) or it is determined based on the filing of an applicable Tax Return that there was an over-accrual of Taxes reflected on the Reference Balance Sheet (such refund, credit and/or over-accrual, a “Tax Refund”), the amount of such Tax Refund (including any interest received from the applicable Governmental Authority, and reduced by any reasonable costs or expenses (including Taxes) incurred in connection with receiving such refunds or credits) that, in any case, increases the value of the Acquired Newco Shares based on the underlying increase in the value of the Companies (for the avoidance of doubt, taking into account the percentage of ownership of Newco Inc. of such owner) (such increases, “Buyer’s Proportionate Share”) shall offset and therefore reduce (on a dollar-for-dollar basis) the amount of any indemnity payment otherwise due to Buyer under this Article X. If Seller has a current obligation to make an indemnity payment under this Article X, Seller shall make such payment in accordance with this Article X without any delays due to an expected or pending Tax Refund. If Seller has already made an indemnity payment under this Article X prior to the Company or any of its Affiliates receiving a Tax Refund, and a Tax Refund is subsequently received by the Company or any of its Affiliates, Seller shall notify Buyer of the receipt of such Tax Refund and, within ten (10) Business Days of Buyer’s receipt of such notice, Buyer shall pay to Seller an amount equal to the lesser of (i) Buyer’s Proportionate Share of such Tax Refund amount or (ii) the amount of indemnity already paid to Buyer under this Article X. If Buyer’s Proportionate Share of such Tax Refund received by the Company or any of its Affiliates exceeds the amount of the indemnity already paid to Buyer under this Article X (an “Excess Tax Refund Amount”), the Excess Tax Refund Amount shall offset and reduce any future subsequent indemnity payments to be made by Seller under this Article X.

Section 10.6    Adjustments for Indemnity Payments. Except as otherwise required by Law, the Parties shall treat for all Tax purposes any indemnification payment made hereunder as an adjustment to the Adjusted Purchase Price.

Section 10.7    Procedure for Indemnification with Respect to Direct Claims. Whenever any direct claim shall arise for indemnification under this Article X (other than Section 10.4(c)), the Indemnified Party, after attaining knowledge of such claim, shall promptly notify the Indemnitor of the claim and, when known, the facts constituting the basis for such claim (such notice, a “Claim Notice”). If within thirty (30) days after receiving a Claim Notice the Indemnitor does not give written notice to the Indemnified Party that it contests such Claim Notice, then the amount of indemnity payable for such claim shall be as set forth in the Indemnified Party’s Claim Notice. If the Indemnitor contests such indemnity, the Parties shall attempt in good faith to reach an agreement with regard thereto within thirty (30) days of delivery of the Indemnitor’s notice objecting to the claim. If the Parties cannot reach agreement within such 30-day period, the matter shall be resolved in accordance with the provisions of Section 11.8.

49

Section 10.8    Procedure for Indemnification with Respect to Third-Party Claims.

(a)    Notice of Claim. If any legal proceedings shall be instituted or any claim or demand shall be asserted by any third party in respect of which indemnification may be sought by any Indemnified Party under this Article X, such Indemnified Party shall, within ten (10) days of the actual receipt by a responsible officer of notice of the institution of such legal proceeding or such claim or demand, submit a Claim Notice to the Indemnitor, specifying the nature of such legal proceedings, claim or demand and the amount or the estimated amount thereof to the extent then determinable, which estimate shall not be binding upon the Indemnified Party; provided, that the failure of an Indemnified Party to give timely notice shall not affect its rights to indemnification under this Article X, except to the extent that the Indemnitor has been actually prejudiced by such failure.

(b)    Conduct of Claim.

(i)    Except with respect to Taxes:

(A)    The Indemnitor shall have the right, at its option and at its own expense, to be represented by counsel of its choice and to participate in, or take control of, the defense, negotiation and/or settlement of any proceeding, claim or demand that relates to any amounts indemnifiable or potentially indemnifiable under this Article X, provided, that the Indemnified Party may participate in any such proceeding with counsel of its choice (which shall be at its own expense). The Indemnified Party shall have a right to notice of any settlement, and the Indemnitor shall not compromise or settle any claim, nor execute or otherwise agree to any consent decree, that (I) provides for other than monetary payment without the Indemnified Party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed or (II) does not include as an unconditional term thereof the giving of a release from all liability with respect to such claim by each claimant or plaintiff to each Indemnified Party that is or may be subject to the third-party claim, without the Indemnified Party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

(B)    If the Indemnitor elects not to defend or settle such proceeding, claim or demand, the Indemnified Party shall provide fifteen (15) days advance written notice of any proposed settlement or compromise to the Indemnitor and shall act reasonably and in accordance with the Indemnified Party’s good faith business judgment. Without the consent of the Indemnitor (not to be unreasonably withheld, conditioned or delayed), no Indemnified Party shall settle or compromise any claim for which it asserts a right to indemnification, nor execute or agree to any consent decree with respect to any such claim, unless (I) the terms of such settlement are substantially the same as the proposed settlement or compromise delivered in the written notice to the Indemnitor or (II) such settlement (x) provides only for the payment of money and does not include any admission of guilt or culpability and (y) includes a full release from all liability with respect to such claim by each claimant or plaintiff to each Indemnitor that is or may be subject to the third-party claim.

50

(C)    The Indemnitor and the Indemnified Party shall cooperate fully with each other in connection with the defense, negotiation or settlement of any such legal proceeding, claim or demand.

(ii)    Notwithstanding anything to the contrary in this Agreement, DPL and AES shall each have the right, at its option and at its own expense, to be represented by counsel of its choice and to participate in, or take control of, the defense, negotiation or settlement of any proceeding, claim or demand that relates to Taxes of Seller or any of its Affiliates (including Newco II Inc. and DP&L).

(c)    Payment of Third-Party Claims. After final non-appealable judgment or award shall have been rendered by a court, arbitration board or administrative agency of competent jurisdiction, or a settlement shall have been consummated, or the Indemnified Party and the Indemnitor shall have arrived at a mutually binding agreement with respect to each separate matter indemnified by the Indemnitor, the Indemnified Party shall forward to the Indemnitor notice of any sums due and owing by the Indemnitor with respect to such matter, and such amount shall be paid within five (5) Business Days by the Indemnitor to the applicable Indemnified Party.

(d)    Access to Information. If any claim is made by a third party against an Indemnified Party, the Indemnified Party shall use commercially reasonable efforts to make available to the Indemnitor those partners, members, officers and employees whose assistance, testimony or presence is necessary to assist the Indemnitor in evaluating and in defending such claims; provided, that any such access shall be conducted in such a manner as not to interfere unreasonably with the operations of the business of the Indemnified Party.

Section 10.9    Subrogation. Except with respect to Taxes, upon payment of a Loss by an Indemnitor to an Indemnified Party pursuant to this Article X, such Indemnitor, without any further action, shall be subrogated to any and all claims that such Indemnified Party or any member of its Indemnified Group may have against third parties relating to such Loss, but only to the extent of the amount paid to such Indemnified Party or any member of its Indemnified Group by such Indemnitor in respect of such Loss, and such Indemnified Party and the members of its Indemnified Group shall use commercially reasonable efforts to cooperate with such Indemnitor, at the expense of such Indemnitor, in order to enable such Indemnitor to pursue such claims.

Section 10.10    Exclusive Remedy. Notwithstanding anything to the contrary which may be contained herein, the indemnities set forth in this Article X shall become effective as of the Closing Date. Other than equitable remedies, the indemnities set forth in this Article X, absent intentional misconduct, intentional or willful misrepresentation or fraud, shall be the exclusive remedies of Buyer and Seller and their respective Indemnified Groups due to the breach or inaccuracy of any representation or warranty, or the breach or default of any covenant or agreement, contained in this Agreement, and the Parties shall not be entitled to a rescission of this Agreement or to any further indemnification rights, breach or damages or claims of any nature whatsoever in respect thereof, all of which the Parties hereby waive.

51

Section 10.11    Damages Disallowed. Except as expressly provided herein, no Party or its Affiliates, or other members of its Indemnified Group, shall be liable hereunder at any time for consequential, exemplary, indirect, special or punitive loss of the other Party or any of the members of their respective Indemnified Groups, whether in contract, tort (including negligence), strict liability or otherwise.

Section 10.12    Certain Tax Benefits. Each Party shall pay to the other Party the amount of any reduction in cash Tax liability of the first Party derived directly from any Loss for which the other Party has indemnified the first Party or any member of its Indemnified Group pursuant to this Article X, but only to the extent such reduction in cash Tax liability occurs in the taxable period during which such Loss is sustained or in the immediately following taxable period. The amount of any reduction in cash Tax liability shall be calculated on a “with and without” basis, taking into account any Taxes imposed on any payments received from the other Party under this Agreement and all other relevant facts, including the first Party’s other Tax attributes.

incurred by any such subsequent purchaser shall be deemed a Loss suffered or incurred by Buyer for purposes of this Agreement (to the extent such Loss would have been a Loss suffered or incurred by Buyer if Buyer was the owner of the Acquired Newco II Shares). This Agreement is not intended to confer any rights or remedies hereunder upon any other Person except the Parties, it being for the exclusive benefit of the Parties and their respective successors and permitted assigns. Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the Agreement Date or as of any other date.

Section 11.5    Amendments. This Agreement may be amended, modified or supplemented, with respect to any of the terms contained in this Agreement, only by written agreement (referring specifically to this Agreement) signed by or on behalf of both Parties.

Section 11.6    Waiver. No waiver of any breach of any of the terms of this Agreement shall be effective unless such waiver is made expressly in an instrument in writing specifically referring to this Agreement and executed and delivered by the Party against whom such waiver is claimed. No waiver of any breach shall be deemed to be a further or continuing waiver of such breach or a waiver of any other or subsequent breach. Except as otherwise expressly provided herein, no failure on the part of any Party to exercise, and no delay in exercising, any right, power or remedy hereunder, or otherwise available in respect hereof at law or in equity, shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof, or the exercise of any other right, power or remedy. The rights and remedies of the Parties are cumulative and are in addition to, and not in substitution for, any other rights and remedies available at law or in equity or otherwise.

Section 11.7    Interpretation.

(a)    When a reference is made in this Agreement to an Article, Section, clause or Exhibit, such reference shall be to an Article, Section or clause of, or Exhibit to, this Agreement unless otherwise indicated, and the words “Agreement,” “hereby,” “herein,” “hereof,” “hereunder” and words of similar import refer to this Agreement as a whole (including any Exhibits) and not merely to the specific section, paragraph or clause in which such word appears and “paragraphs” or “clauses” shall be deemed references to separate paragraphs or clauses of the Section in which the reference occurs. The table of contents and the Article and Section headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the Parties and do not in any way affect the meaning or interpretation of this Agreement. The phrases “the date of this Agreement,” “the date hereof” and terms of similar import, shall be deemed to refer to the Agreement Date. References to any statute are to that statute, as amended from time to time, and to the rules and regulations promulgated thereunder. Unless otherwise expressly provided herein, references to any agreement or document shall be a reference to such agreement or document as amended, modified or supplemented and in effect from time to time and shall include reference to all exhibits, schedules and other documents or agreements attached thereto or incorporated therein, including waivers or consents. Unless otherwise expressly provided herein, references to any Person include the successors and permitted assigns of that Person. Whenever the content of this Agreement permits, the

54

masculine gender shall include the feminine and neuter genders, and a reference to singular or plural shall be interchangeable with the other. References from or through any date mean, unless otherwise specified, from and including or through and including, respectively. Where this Agreement states that a Party “shall,” “will” or “must” perform in some manner or otherwise act or omit to act, it means that such Party is legally obligated to do so in accordance with this Agreement. As used in this Agreement: (i) the term “including” and words of similar import mean “including, without limitation” unless otherwise specified, (ii) “$” and “dollars” refer to the currency of the United States of America, (iii) “or” shall include both the conjunctive and disjunctive and (iv) “any” shall mean “one or more”. Unless the defined term “Business Days” is used, references to “days” in this Agreement refer to calendar days. Any Contract, document, list or other item shall be deemed to have been “provided” or “made available” to Buyer for all purposes of this Agreement if such Contract, document, list or other item was offered to be made available or made available to Buyer or any of its Representatives, including by being posted in the Data Room or by delivery of any kind of physical or electronic copy thereof, two (2) Business Days prior to the date hereof.

(b)    The Parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provision of this Agreement.

(c)    No summary of this Agreement prepared by or on behalf of any Party shall affect the meaning or interpretation of this Agreement.

Section 11.8    Governing Law; Consent to Jurisdiction; WAIVER OF JURY TRIAL.

(a)    This Agreement, the legal relations between the Parties and the adjudication and the enforcement thereof, shall be governed by and interpreted and construed in accordance with the substantive laws of the State of New York, without regard to applicable choice of law provisions thereof.

(b)    Each Party, by its execution hereof, (i) hereby irrevocably submits and consents to the exclusive jurisdiction of the state courts of the State of New York located in New York County or the United States District Court for the Southern District of New York (each, a “NY Court”) for the purpose of any and all actions, suits or proceedings arising in whole or in part out of, related to, based upon or in connection with this Agreement or the subject matter hereof (each, a “Proceeding”), (ii) hereby waives to the extent not prohibited by applicable Law, and agrees not to assert, by way of motion, as a defense or otherwise, in any Proceeding, any claim that it is not subject to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution or that any such action brought in one of the above-named courts should be dismissed on grounds of forum non conveniens, should be transferred to any court other than one of the above-named courts or should be stayed by reason of the pendency of some other proceeding in any other court other than one of the above-named courts, or that this Agreement or the subject matter hereof may not be enforced in or by such

55

court and (iii) hereby agrees not to commence any Proceeding other than before one of the above-named courts nor to make any motion or take any other action seeking or intending to cause the transfer or removal of any Proceeding to any court other than one of the above-named courts whether on the grounds of inconvenient forum or otherwise. Each Party hereby (A) consents to service of process in any such action in any manner permitted by New York Law, (B) agrees that service of process made in accordance with clause (A) or made by registered or certified mail, return receipt requested, at its address specified pursuant to Section 11.2, shall constitute good and valid service of process in any Proceeding and (C) waives and agrees not to assert (by way of motion, as a defense or otherwise) in any Proceeding any claim that service of process made in accordance with clauses (A) or (B) does not constitute good and valid service of process.

(c)    EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY PROCEEDING OR OTHER CONTROVERSY WHICH MAY ARISE IN CONNECTION WITH THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUCH PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS, OR THE FORMATION, BREACH, TERMINATION OR VALIDITY OF THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) IT MAKES THIS WAIVER VOLUNTARILY AND (IV) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 11.8.

(d)    Each of the Parties hereby agrees, with respect to any Proceeding, (i) to take all actions necessary to consolidate and join together such Proceeding with any other action, suit or proceeding arising in whole or in part out of, related to, based upon or in connection with the Transactions or the subject matters thereof (each, a “Related Proceeding”); (ii) that any Related Proceeding necessarily would involve common questions of law or fact and arise under the same related transactions, such that consolidation and joinder would be necessary to guard against oppression or abuse, prevent delay, save unnecessary expense, further judicial economy and convenience, and avoid divergent decisions or findings of law or fact; and (iii) not to assert, by way of a claim, cause of action, motion, defense or otherwise, in any action, suit or proceeding, any argument or contention that is inconsistent in any respect with this Section 11.8(d); provided, however, that this Section 11.8(d) shall not be given effect if and to the extent that it would contradict the application of any express dispute resolution provision provided in the Newco II Shareholders Agreement or any other Contract related to the Transactions with respect to disputes expressly covered by those Contracts.

Section 11.9    Specific Performance. The Parties agree that irreparable harm would occur and the Parties would not have any adequate remedy at law in the event that any of

56

the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which they are entitled at law or in equity. The Parties hereby waive, in any action for specific performance, the defense of adequacy of a remedy at law and the posting of any bond or other undertaking or security in connection therewith. The Parties further agree that (a) by seeking any remedy provided in this Section 11.9, a Party shall not in any respect waive its right to seek any other form of relief that may be available to it under this Agreement and (b) nothing contained in this Section 11.9 shall require a Party to institute any action for (or limit a Party’s right to institute any action for) specific performance under this Section 11.9 prior to exercising any other right under this Agreement. No right or remedy herein conferred by this Agreement is intended to be exclusive of any other right or remedy permitted by this Agreement, and each such other permitted right and remedy shall be cumulative and in addition to each such other permitted right and remedy given hereunder or, subject to the terms of this Agreement, now or hereafter existing at law, in equity, under Contract or otherwise.

Section 11.10    Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which shall constitute one (1) and the same Agreement.

Overview and Summary of Significant Accounting Policies

OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DPL, an indirectly wholly-owned subsidiary of AES, is a holding company organized in 1985 under the laws of Ohio. DPL owns all of the outstanding common stock of DP&L, which does business as AES Ohio. Substantially all of DPL’s business consists of transmitting, distributing and selling of electric energy conducted through its principal subsidiary, AES Ohio. The terms “we,” “us,” “our” and “ours” are used to refer to DPL and its subsidiaries.

AES Ohio is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave Ohio consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, retail transmission and distribution services are still regulated. AES Ohio has the exclusive right to provide such transmission and distribution services to approximately 541,000 customers located in West Central Ohio. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. AES Ohio also provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. AES Ohio sources all of the generation for its SSO customers through a competitive bid process. AES Ohio's sales reflect the general economic conditions, seasonal weather patterns of the area, the market price of electricity and customer energy efficiency initiatives. AES Ohio owns numerous transmission facilities. AES Ohio records revenue and expenses for its proportional share of energy and capacity from its investment in OVEC.

DPL’s other primary subsidiaries are MVIC and Miami Valley Lighting. MVIC is our captive insurance company that provides insurance services to AES Ohio and our other subsidiaries, and Miami Valley Lighting provides street and outdoor lighting services to customers in the Dayton region. DPL's subsidiaries are all wholly-owned. DPL also has a wholly-owned business trust, DPL Capital Trust II, formed for the purpose of issuing trust capital securities to investors.

AES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, AES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses and records regulatory assets when incurred costs are expected to be recovered in future customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs or overcollections of riders.

Agreement to Sell Minority Interest in AES Ohio

On September 13, 2024, DPL entered into (i) a Purchase and Sale Agreement with Astrid Holdings LP ("Investor"), a wholly-owned subsidiary of Caisse de dépôt et placement du Québec ("CDPQ"), pursuant to which DPL agreed to sell to Investor 15% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Holdings, Inc. ("Ohio Holdings" and, such agreement, the "Ohio Holdings Purchase Agreement") for a purchase price of approximately $273 million, subject to adjustment, and (ii) a Purchase and Sale Agreement with Investor, pursuant to which DPL agreed to sell to Investor 17.65% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Investments, Inc. ("Ohio Investments" and, such agreement, the "Ohio Investments Purchase Agreement" and together with the Ohio Holdings Purchase Agreement, the "Purchase Agreements") for a purchase price of approximately $273 million, subject to adjustment. Upon consummation of the transactions contemplated by the Ohio Holdings Purchase Agreement and the Ohio Investments Purchase Agreement together, the ("Closings"), CDPQ will own an aggregate indirect equity interest in AES Ohio of approximately 30%, with total proceeds to DPL of approximately $546 million, subject to adjustment.

It is anticipated that the Closings will occur on the same day in the first half of 2025. There will be no change in management or operational control of DPL, Ohio Investments, Ohio Holdings or AES Ohio as a result of these transactions.

The purchases and sales of the shares of capital stock of each of Ohio Holdings and Ohio Investments contemplated under each of the Purchase Agreements are subject to the satisfaction of certain customary conditions described in the Purchase Agreements, including, among others, receipt of the approval of the Public Utilities Commission of Ohio, the Federal Energy Regulatory Commission and completion of review by the Committee on Foreign Investments in the United States. In addition, each of the parties to the Purchase Agreements has agreed to customary covenants therein.

In connection with the Closings, Investor, Ohio Investments and DPL will enter into a Shareholders' Agreement with respect to Ohio Investments (the "Shareholders' Agreement"), the form of which has been agreed to by the parties. The Shareholders' Agreement will establish the general framework governing the relationship between and among Investor and the Company, and their respective successors and transferees, as shareholders of Ohio Investments. In addition, Investor, Ohio Holdings and Ohio Investments will also enter into a Shareholders' Agreement with respect to Ohio Holdings with substantially identical terms.

Consolidation

DPL’s Condensed Consolidated Financial Statements include the accounts of DPL and its wholly-owned subsidiaries except for DPL Capital Trust II, which is not consolidated consistent with the provisions of GAAP. All material intercompany accounts and transactions are eliminated in consolidation. We have evaluated subsequent events through the date this report was issued.

Interim Financial Presentation

The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASC, for interim financial information and Article 10 of Regulation S-X issued by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income or loss, changes in shareholder's equity, and cash flows. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of expected results for the year ending December 31, 2024. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2023 audited consolidated financial statements and footnotes thereto, which are included in our Form 10-K.

Use of Management Estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the revenue and expenses of the periods reported. Actual results could differ from these estimates and assumptions. Significant items subject to such estimates and assumptions include: the carrying value of property, plant and equipment; unbilled revenue; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits.

ASU Number and Name	Description	Date of Adoption	Effect on the financial statements upon adoption
2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures	The amendments in this section are designed to improve the disclosures related to segment reporting on an interim and annual basis. Public companies must disclose significant segment expenses and an amount for other segment items. This will also require that a company disclose its annual disclosures under Topic 280 in each interim period. Furthermore, companies will need to disclose the Chief Operating Decision Maker (“CODM”) and how the CODM assesses the performance of a segment. Lastly, public companies that have a single reportable segment must report the required disclosures under Topic 280.	The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted.	This ASU only affects disclosures, which will be provided when the amendment becomes effective.
2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures	The amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. Furthermore, companies are required to disclose a disaggregated amount of income taxes paid at a federal, state, and foreign level as well as a breakdown of income taxes paid in a jurisdiction that comprises 5% of a company's total income taxes paid. Lastly, this ASU requires that companies disclose income (loss) from continuing operations before income tax at a domestic and foreign level and that companies disclose income tax expense from continuing operations on a federal, state, and foreign level.	The amendments in this Update are effective for fiscal years beginning after December 15, 2024.	This ASU only affects disclosures, which will be provided when the amendment becomes effective.

On September 13, 2024, AES Ohio reached a settlement with the PUCO Staff and other parties on the pending Smart Grid Phase 2 Application. The Settlement will provide for a four-year plan to invest $240.5 million of capital and $18.6 million of operations and maintenance expense related to grid modernization, support of Distributed Energy Resources and Economic Development and an enhanced Telecommunications network. These costs will be recovered through the existing Investment Infrastructure Rider. If approved, AES Ohio will implement a comprehensive grid modernization project that will deliver benefits to customers, society as a whole and to AES Ohio. An evidentiary hearing was held on October 29, 2024, and we expect an order from the PUCO by the second quarter of 2025, prior to the end of Smart Grid Phase 1.

Fair Value

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]

Fair Value

FAIR VALUE

The fair value of our financial assets and liabilities approximates their reported carrying amounts. The estimated fair values of our assets and liabilities have been determined using available market information. Because these amounts are estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. For further information on our valuation techniques and policies, see Note 4. Fair Value in Item 8. Financial Statements and Supplementary Data of our Form 10-K.

Financial Assets

AES Ohio established a Master Trust to hold assets that could be used for the benefit of employees participating in employee benefit plans. These assets are not used for general operating purposes. These assets are primarily comprised of open-ended mutual funds, which are valued using the net asset value per unit. These assets are recorded at fair value within Other non-current assets on the Condensed Consolidated Balance Sheets and are classified as equity investments. Net unrealized gains / (losses) related to equity investments still held as of September 30, 2024 and 2023 are as follows:

	Three months ended				Nine months ended
	September 30,				September 30,
$ in millions	2024		2023		2024		2023
Net unrealized gains / (losses) (a)	$	0.4	$	(0.2)	$	0.7	$	0.2

(a)    These amounts are included in Other income, net in our Condensed Consolidated Statements of Operations.

We did not have any transfers of the fair values of our financial instruments between Level 1, Level 2 or Level 3 of the fair value hierarchy during the nine months ended September 30, 2024 or 2023.

Recurring Fair Value Measurements

The fair value of assets and liabilities as of September 30, 2024 and December 31, 2023 measured on a recurring basis and the respective category within the fair value hierarchy for DPL is as follows:

	Fair value as of September 30, 2024								Fair value as of December 31, 2023

Financial Instruments not Measured at Fair Value in the Condensed Consolidated Balance Sheets

The fair value of long-term debt is based on current public market prices for disclosure purposes only. These fair value inputs are considered Level 2 in the fair value hierarchy. As the Wright-Patterson Air Force Base note is not publicly traded, the fair value inputs are considered Level 3 in the fair value hierarchy as there are no observable inputs. Unrealized gains or losses are not recognized in the financial statements as long-term debt is presented at carrying value, net of unamortized premium or discount and unamortized deferred financing costs. The long-term debt amounts include the current portion payable in the next twelve months and have maturities that range from 2025 to 2061.

The following table presents the carrying amount, fair value, and fair value hierarchy of our financial liabilities that are not measured at fair value in the Condensed Consolidated Balance Sheets as of the periods indicated, but for which fair value is disclosed:

We did not have any transfers of the fair values of our financial instruments between Level 1, Level 2 or Level 3 of the fair value hierarchy during the nine months ended September 30, 2024 or 2023.

Recurring Fair Value Measurements

The fair value of assets and liabilities as of September 30, 2024 and December 31, 2023 measured on a recurring basis and the respective category within the fair value hierarchy for AES Ohio is as follows:

Financial Instruments not Measured at Fair Value in the Condensed Balance Sheets

The fair value of long-term debt is based on current public market prices for disclosure purposes only. These fair value inputs are considered Level 2 in the fair value hierarchy. As the Wright-Patterson Air Force Base note is not publicly traded, the fair value inputs are considered Level 3 in the fair value hierarchy as there are no observable inputs. Unrealized gains or losses are not recognized in the financial statements as long-term debt is presented at carrying value, net of unamortized premium or discount and unamortized deferred financing costs. The long-term debt amounts include the current portion payable in the next twelve months and have maturities that range from 2027 to 2061.

The following table presents the carrying amount, fair value, and fair value hierarchy of our financial liabilities that are not measured at fair value in the Condensed Balance Sheets as of the periods indicated, but for which fair value is disclosed:

Revolving credit agreements

As of September 30, 2024 and December 31, 2023, the AES Ohio Credit Agreement had outstanding borrowings of $45.0 million and $15.0 million, respectively.

Significant Transactions

In August 2024, AES Ohio entered into an unsecured $150.0 million 364-day term loan agreement ("AES Ohio Term Loan"). The AES Ohio Term Loan was fully drawn at closing with the proceeds being used for general corporate purposes. This agreement matures on August 13, 2025, and bears interest at variable rates as described in the $150 million Term Loan Agreement. The AES Ohio Term Loan contains customary representations, warranties and

covenants, including a leverage covenant consistent with the leverage covenant contained in AES Ohio's Credit Agreement. AES Ohio has classified the AES Ohio Term Loan as short-term indebtedness as it matures in August 2025. Management plans to repay the AES Ohio Term Loan Agreement through a combination of funds from debt financings and parent equity capital contributions.

DPL's Senior unsecured notes

DPL has $415.0 million of 4.125% Senior unsecured notes due July 1, 2025 ("2025 DPL Notes"). Although current liquid funds are not sufficient to repay the amounts due under the 2025 DPL Notes at maturity, we will use a portion of the proceeds from the Closings to repay the notes in full (see Note 1. Overview and Summary of Significant Accounting Policies - Agreement to Sell Minority Interest in AES Ohio for more information).

Long-term debt covenants and restrictions

The AES Ohio Credit Agreement, AES Ohio Term Loan, and Fifty-Third, Fifty-Fourth and Fifty-Fifth Supplemental Indentures to the First Mortgage, pursuant to which the 3.20% Bonds due 2040, the 5.19% Bonds due 2033, the 5.49% Bonds due 2028 and the 5.70% Bonds due 2033 were issued, respectively, each contain one financial covenant. The covenant measures Total Debt to Total Capitalization and is calculated, at the end of each fiscal quarter, by dividing total debt at the end of the quarter by total capitalization at the end of the quarter. AES Ohio’s Total Debt to Total Capitalization ratio shall not be greater than 0.67 to 1.00. As of September 30, 2024, AES Ohio was in compliance with this financial covenant.

AES Ohio does not have any meaningful restrictions in its debt financing documents prohibiting dividends and return of capital payments to its parent, DPL. As of September 30, 2024, AES Ohio was in compliance with all debt covenants, including the financial covenant described above.

Income Taxes

INCOME TAXES

DPL’s provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. The effective combined state and federal income tax rates were as follows:

	Three months ended				Nine months ended
	September 30,				September 30,
	2024		2023		2024		2023
Effective tax rate	(267.9)	%	19.9	%	(24.9)	%	13.3	%

The year-to-date rate is different from the combined federal and state statutory rate of 22.4% primarily due to the flowthrough of the net tax benefit related to the reversal of excess deferred taxes of AES Ohio as a percentage of pre-tax book income or loss. AES Ohio began amortizing a deferred municipal tax shortage in September 2023, which partially offsets the ongoing amortization of the TCJA benefit.

DPL's income tax expense for the nine months ended September 30, 2024 was calculated using the estimated annual effective income tax rate for 2024 of (53.1)% on ordinary income. Management estimates the annual effective tax rate based on its forecast of annual pre-tax income or loss. DPL's current period tax benefit was calculated using the limitations prescribed in ASC 740-270-30-30 through 740-270-30-33.

AES files federal and state income tax returns, which consolidate DPL and its subsidiaries. Under a tax sharing agreement with AES, DPL is responsible for the income taxes associated with its own taxable income and records the provision for income taxes using a separate return method.

Legal Matters

In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under various laws and regulations. We believe the amounts provided in our Condensed Consolidated Financial Statements, as prescribed by GAAP, are adequate considering the probable and estimable contingencies. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various legal proceedings, claims, tax examinations and other matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in our Condensed Consolidated Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided as of September 30, 2024, cannot be reasonably determined.

Environmental Matters

We are subject to various federal, state, regional and local environmental protection and health and safety laws and regulations governing, among other things, the generation, storage, handling, use, disposal and transportation of regulated materials, including ash and CCR; the use and discharge of water used in generation boilers and for cooling purposes; the emission and discharge of hazardous and other materials, including GHGs, into the environment; climate change; species and habitat protections; and the health and safety of our employees. These laws and regulations often require a lengthy and complex process of obtaining and renewing permits and other governmental authorizations from federal, state and local agencies. Violation of these laws, regulations or permits

can result in substantial fines, other sanctions, permit revocation and/or facility shutdowns. We cannot assure that we have been or will be at all times in full compliance with such laws, regulations and permits.

Where no accrued liability has been recognized, it is reasonably possible that some matters could be decided unfavorably to us and could require us to pay damages or make expenditures in amounts that could be material but could not be estimated as of September 30, 2024.

We have taken steps to limit our exposure to environmental claims that could be raised with respect to our previously-owned and operated coal-fired generation units, but we cannot predict whether any such claims will be raised and, if they are, the extent to which they may have a material adverse effect on our results of operations, financial condition and cash flows.

Accruals for legal loss and environmental contingencies were not material as of September 30, 2024 and December 31, 2023.

Equity Ownership Interest

AES Ohio has a 4.9% equity ownership interest in OVEC, which is recorded using the cost method of accounting under GAAP. AES Ohio, along with several non-affiliated energy companies party to an OVEC arrangement, receive and pay for OVEC capacity and energy and are responsible for OVEC debt obligations and other fixed costs in proportion to their power participation ratios under the arrangement, which, for AES Ohio, is the same as its equity ownership interest. As of September 30, 2024, AES Ohio could be responsible for the repayment of 4.9%, or $49.7 million, of $1.0 billion OVEC debt obligations if they came due, comprised of fixed rate securities with maturities from 2026 to 2040. OVEC could also seek additional contributions from AES Ohio to avoid a default in the event that other OVEC members defaulted on their respective OVEC obligations.

BUSINESS SEGMENTS

DPL manages its business through one reportable operating segment, the Utility segment. The primary segment performance measure is income / (loss) before income tax as management has concluded that this measure best reflects the underlying business performance of DPL and is the most relevant measure considered in DPL’s internal evaluation of the financial performance of its segment. The Utility segment is comprised of AES Ohio, a public electric transmission and distribution utility, with all other nonutility business activities aggregated separately. See Note 1. Overview and Summary of Significant Accounting Policies for further information on AES Ohio. The “Other” nonutility category primarily includes interest expense, cash and other immaterial balances. The accounting policies of the identified segment are consistent with those policies and procedures described in the summary of significant accounting policies.

Description of Business

DPL, an indirectly wholly-owned subsidiary of AES, is a holding company organized in 1985 under the laws of Ohio. DPL owns all of the outstanding common stock of DP&L, which does business as AES Ohio. Substantially all of DPL’s business consists of transmitting, distributing and selling of electric energy conducted through its principal subsidiary, AES Ohio. The terms “we,” “us,” “our” and “ours” are used to refer to DPL and its subsidiaries.

AES Ohio is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave Ohio consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, retail transmission and distribution services are still regulated. AES Ohio has the exclusive right to provide such transmission and distribution services to approximately 541,000 customers located in West Central Ohio. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. AES Ohio also provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. AES Ohio sources all of the generation for its SSO customers through a competitive bid process. AES Ohio's sales reflect the general economic conditions, seasonal weather patterns of the area, the market price of electricity and customer energy efficiency initiatives. AES Ohio owns numerous transmission facilities. AES Ohio records revenue and expenses for its proportional share of energy and capacity from its investment in OVEC.

DPL’s other primary subsidiaries are MVIC and Miami Valley Lighting. MVIC is our captive insurance company that provides insurance services to AES Ohio and our other subsidiaries, and Miami Valley Lighting provides street and outdoor lighting services to customers in the Dayton region. DPL's subsidiaries are all wholly-owned. DPL also has a wholly-owned business trust, DPL Capital Trust II, formed for the purpose of issuing trust capital securities to investors.

AES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, AES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses and records regulatory assets when incurred costs are expected to be recovered in future customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs or overcollections of riders.

Agreement to Sell Minority Interest in AES Ohio

On September 13, 2024, DPL entered into (i) a Purchase and Sale Agreement with Astrid Holdings LP ("Investor"), a wholly-owned subsidiary of Caisse de dépôt et placement du Québec ("CDPQ"), pursuant to which DPL agreed to sell to Investor 15% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Holdings, Inc. ("Ohio Holdings" and, such agreement, the "Ohio Holdings Purchase Agreement") for a purchase price of approximately $273 million, subject to adjustment, and (ii) a Purchase and Sale Agreement with Investor, pursuant to which DPL agreed to sell to Investor 17.65% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Investments, Inc. ("Ohio Investments" and, such agreement, the "Ohio Investments Purchase Agreement" and together with the Ohio Holdings Purchase Agreement, the "Purchase Agreements") for a purchase price of approximately $273 million, subject to adjustment. Upon consummation of the transactions contemplated by the Ohio Holdings Purchase Agreement and the Ohio Investments Purchase Agreement together, the ("Closings"), CDPQ will own an aggregate indirect equity interest in AES Ohio of approximately 30%, with total proceeds to DPL of approximately $546 million, subject to adjustment.

It is anticipated that the Closings will occur on the same day in the first half of 2025. There will be no change in management or operational control of DPL, Ohio Investments, Ohio Holdings or AES Ohio as a result of these transactions.

The purchases and sales of the shares of capital stock of each of Ohio Holdings and Ohio Investments contemplated under each of the Purchase Agreements are subject to the satisfaction of certain customary conditions described in the Purchase Agreements, including, among others, receipt of the approval of the Public Utilities Commission of Ohio, the Federal Energy Regulatory Commission and completion of review by the Committee on Foreign Investments in the United States. In addition, each of the parties to the Purchase Agreements has agreed to customary covenants therein.

In connection with the Closings, Investor, Ohio Investments and DPL will enter into a Shareholders' Agreement with respect to Ohio Investments (the "Shareholders' Agreement"), the form of which has been agreed to by the parties. The Shareholders' Agreement will establish the general framework governing the relationship between and among Investor and the Company, and their respective successors and transferees, as shareholders of Ohio Investments. In addition, Investor, Ohio Holdings and Ohio Investments will also enter into a Shareholders' Agreement with respect to Ohio Holdings with substantially identical terms.

Financial Statement Presentation

DPL’s Condensed Consolidated Financial Statements include the accounts of DPL and its wholly-owned subsidiaries except for DPL Capital Trust II, which is not consolidated consistent with the provisions of GAAP. All material intercompany accounts and transactions are eliminated in consolidation. We have evaluated subsequent events through the date this report was issued.

Interim Financial Presentation

The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASC, for interim financial information and Article 10 of Regulation S-X issued by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income or loss, changes in shareholder's equity, and cash flows. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of expected results for the year ending December 31, 2024. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2023 audited consolidated financial statements and footnotes thereto, which are included in our Form 10-K.

Use of Management Estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the revenue and expenses of the periods reported. Actual results could differ from these estimates and assumptions. Significant items subject to such estimates and assumptions include: the carrying value of property, plant and equipment; unbilled revenue; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits.

Accounting for Taxes Collected from Customers and Remitted to Governmental Authorities

In August 2024, AES Ohio entered into an unsecured $150.0 million 364-day term loan agreement ("AES Ohio Term Loan"). The AES Ohio Term Loan was fully drawn at closing with the proceeds being used for general corporate purposes.

The AES Ohio Term Loan contains customary representations, warranties and

covenants, including a leverage covenant consistent with the leverage covenant contained in AES Ohio's Credit Agreement.

DPL's Senior unsecured notes

DPL has $415.0 million of 4.125% Senior unsecured notes due July 1, 2025 ("2025 DPL Notes"). Although current liquid funds are not sufficient to repay the amounts due under the 2025 DPL Notes at maturity, we will use a portion of the proceeds from the Closings to repay the notes in full (see Note 1. Overview and Summary of Significant Accounting Policies - Agreement to Sell Minority Interest in AES Ohio for more information).

The covenant measures Total Debt to Total Capitalization and is calculated, at the end of each fiscal quarter, by dividing total debt at the end of the quarter by total capitalization at the end of the quarter. AES Ohio’s Total Debt to Total Capitalization ratio shall not be greater than 0.67 to 1.00. As of September 30, 2024, AES Ohio was in compliance with this financial covenant.

AES Ohio does not have any meaningful restrictions in its debt financing documents prohibiting dividends and return of capital payments to its parent, DPL. As of September 30, 2024, AES Ohio was in compliance with all debt covenants, including the financial covenant described above.

On September 13, 2024, AES Ohio reached a settlement with the PUCO Staff and other parties on the pending Smart Grid Phase 2 Application. The Settlement will provide for a four-year plan to invest $240.5 million of capital and $18.6 million of operations and maintenance expense related to grid modernization, support of Distributed Energy Resources and Economic Development and an enhanced Telecommunications network. These costs will be recovered through the existing Investment Infrastructure Rider. If approved, AES Ohio will implement a comprehensive grid modernization project that will deliver benefits to customers, society as a whole and to AES Ohio. An evidentiary hearing was held on October 29, 2024, and we expect an order from the PUCO by the second quarter of 2025, prior to the end of Smart Grid Phase 1.

Revolving credit agreements

As of September 30, 2024 and December 31, 2023, the AES Ohio Credit Agreement had outstanding borrowings of $45.0 million and $15.0 million, respectively.

Significant Transactions

In August 2024, AES Ohio entered into an unsecured $150.0 million 364-day term loan agreement ("AES Ohio Term Loan"). The AES Ohio Term Loan was fully drawn at closing with the proceeds being used for general corporate purposes. This agreement matures on August 13, 2025, and bears interest at variable rates as described in the $150 million Term Loan Agreement. The AES Ohio Term Loan contains customary representations, warranties and

covenants, including a leverage covenant consistent with the leverage covenant contained in AES Ohio's Credit Agreement. AES Ohio has classified the AES Ohio Term Loan as short-term indebtedness as it matures in August 2025. Management plans to repay the AES Ohio Term Loan Agreement through a combination of funds from debt financings and parent equity capital contributions.

DPL's Senior unsecured notes

DPL has $415.0 million of 4.125% Senior unsecured notes due July 1, 2025 ("2025 DPL Notes"). Although current liquid funds are not sufficient to repay the amounts due under the 2025 DPL Notes at maturity, we will use a portion of the proceeds from the Closings to repay the notes in full (see Note 1. Overview and Summary of Significant Accounting Policies - Agreement to Sell Minority Interest in AES Ohio for more information).

Long-term debt covenants and restrictions

The AES Ohio Credit Agreement, AES Ohio Term Loan, and Fifty-Third, Fifty-Fourth and Fifty-Fifth Supplemental Indentures to the First Mortgage, pursuant to which the 3.20% Bonds due 2040, the 5.19% Bonds due 2033, the 5.49% Bonds due 2028 and the 5.70% Bonds due 2033 were issued, respectively, each contain one financial covenant. The covenant measures Total Debt to Total Capitalization and is calculated, at the end of each fiscal quarter, by dividing total debt at the end of the quarter by total capitalization at the end of the quarter. AES Ohio’s Total Debt to Total Capitalization ratio shall not be greater than 0.67 to 1.00. As of September 30, 2024, AES Ohio was in compliance with this financial covenant.

AES Ohio does not have any meaningful restrictions in its debt financing documents prohibiting dividends and return of capital payments to its parent, DPL. As of September 30, 2024, AES Ohio was in compliance with all debt covenants, including the financial covenant described above.

Substantially all property, plant & equipment of AES Ohio is subject to the lien of the mortgage securing AES Ohio’s First and Refunding Mortgage.
