Notes to Unaudited Condensed Consolidated Financial Statements

For the three and six months ended June 30, 2022 and 2021

1. Overview and Summary of Significant Accounting Policies

DPL is a regional energy company organized in 1985 under the laws of Ohio. DPL has one reportable segment, the Utility segment. See Note 9 – Business Segments for more information relating to this reportable segment. The terms “we,” “us,” “our” and “ours” are used to refer to DPL and its subsidiaries.

DPL is an indirectly wholly-owned subsidiary of AES. DP&L, a wholly-owned subsidiary of DPL that 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 535,000 customers located in West Central Ohio. Additionally, AES Ohio 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. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. 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 sells its proportional share of energy and capacity from its investment in OVEC into the wholesale market.

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. In prior periods, AES Ohio Generation was also a primary subsidiary and sold all of its energy and capacity into the wholesale market. AES Ohio Generation retired its only remaining operating asset in May 2020 and sold it in June 2020. See Note 11 – Discontinued Operations for more information. 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.

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.

Certain immaterial amounts from prior periods have been reclassified to conform to the current period presentation. All material intercompany accounts and transactions are eliminated in consolidation.

Interim Financial Presentation

The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASB ASC, 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, changes in common shareholder's deficit, and cash flows. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of expected results for the year ending December 31, 2022. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2021 audited consolidated financial statements and notes 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 revenues and expenses of the periods reported. Actual results could differ from these estimates and assumptions.

15

Table of Contents

Significant items subject to such estimates and assumptions include: recognition of revenue including unbilled revenues; the carrying value of property, plant and equipment; 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; and assets and liabilities related to employee benefits.

Cash, Cash Equivalents and Restricted Cash

The following table summarizes cash, cash equivalents, and restricted cash amounts reported on the Condensed Consolidated Balance Sheets that reconcile to the total of such amounts as shown on the Condensed Consolidated Statements of Cash Flows:

$ in millions	June 30, 2022		December 31, 2021
Cash and cash equivalents	$	60.3	$	26.6
Restricted cash (included in Prepayments and other current assets)	0.1		0.1
Cash, Cash Equivalents, and Restricted Cash, End of Period	$	60.4	$	26.7

Accounts Receivable and Allowance for Credit Losses

The following table summarizes accounts receivable as of June 30, 2022 and December 31, 2021:

	June 30,		December 31,
$ in millions	2022		2021
Accounts receivable, net:
Customer receivables	$	56.9	$	42.3
Unbilled revenue	18.8		19.2
Amounts due from affiliates	4.5		3.1
Due from PJM transmission enhancement settlement	1.7		1.7
Other	3.5		5.5
Allowance for credit losses	(0.3)		(0.3)
Total accounts receivable, net	$	85.1	$	71.5

The following table is a roll forward of our allowance for credit losses related to the accounts receivable balances for the six months ended June 30, 2022 and 2021:

$ in millions	Beginning Allowance Balance		Current Period Provision		Write-offs Charged Against Allowances		Recoveries Collected		Ending Allowance Balance
2022	$	0.3	$	0.7	$	(1.1)	$	0.4	$	0.3
2021	$	2.8	$	(0.2)	$	(1.6)	$	0.7	$	1.7

The allowance for credit losses primarily relates to utility customer receivables, including unbilled amounts. Expected credit loss estimates are developed by disaggregating customers into those with similar credit risk characteristics and using historical credit loss experience. In addition, we also consider how current and future economic conditions are expected to impact collectability, as applicable, including the economic impacts of the COVID-19 pandemic on our receivable balance as of June 30, 2022. Amounts are written off when reasonable collections efforts have been exhausted. During 2021, the current period provision and allowance for credit losses decreased due to lower past due customer receivable balances.

Inventories

Inventories consist of materials and supplies as of June 30, 2022 and December 31, 2021.

New Accounting Pronouncements Adopted in 2022

The following table provides a brief description of recent accounting pronouncements that had an impact on our consolidated financial statements.

ASU Number and Name	Description	Date of Adoption	Effect on the financial statements upon adoption
2020-04 and 2021-01, Reference Rate Form (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting	The amendments in these updates provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference to LIBOR or another reference rate expected to be discontinued by reference rate reform, and clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. These amendments are effective for a limited period of time (March 12, 2020 - December 31, 2022).	Effective for all entities as of March 12, 2020 through December 31, 2022	We are implementing the reference rate reform and do not expect these amendments to have a material impact on our consolidated financial statements. See Implementation for further details.

New Accounting Pronouncements Issued But Not Yet Effective

We have assessed and determined that the new accounting pronouncements issued but not yet effective are not expected to have a material impact on our consolidated financial statements.

2. Regulatory Matters

Distribution Rate Case

On November 30, 2020, AES Ohio filed a new distribution rate case with the PUCO. This rate case proposes a revenue increase of $120.8 million per year and incorporates the DIR investments that were planned and approved in the last rate case but not yet included in distribution rates, other distribution investments since September 2015 and investments necessitated by the tornados that occurred on Memorial Day in 2019. The rate case also includes a proposal for increased tree-trimming expenses and certain customer demand-side management programs and recovery of prior-approved regulatory assets for tree trimming, uncollectible expenses and rate case expense. A hearing on this case was held in January 2022, and the case is pending a commission order. Certain parties that have intervened in the distribution rate case have argued that ESP 1 incorporates a distribution rate freeze. Oral arguments regarding the potential rate freeze were held in May 2022. We are unable to predict the outcome of the distribution rate case, but if the PUCO were to impose a rate freeze that precludes AES Ohio’s ability to implement a distribution rate increase during ESP 1, it could have a material adverse effect on our results of operations, financial condition and cash flows.

3. Fair Value

The fair value of current financial assets and liabilities and other deposits approximate 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 and 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 investments are recorded at fair value within Other non-current assets on the Condensed Consolidated Balance Sheets and classified as equity investments. We recorded net unrealized gains / (losses) of $(0.9) million and $0.3 million during the three months ended June 30, 2022 and 2021, respectively, and $(1.6) million and $0.5 million during the six months ended June 30, 2022 and 2021, respectively. These amounts are included in "Other income" in our Condensed Consolidated Statements of Operations.

Recurring Fair Value Measurements

The following table presents the fair value, carrying value and cost of our non-derivative instruments as of June 30, 2022 and December 31, 2021.

	June 30, 2022				December 31, 2021
$ in millions	Cost		Fair Value		Cost		Fair Value
Assets
Money market funds	$	0.4	$	0.4	$	0.4	$	0.4

Debt securities	3.7		3.3		3.8		3.9
Total	$	5.9	$	7.5	$	6.1	$	9.4

These financial instruments are not subject to master netting agreements or collateral requirements and, as such, are presented in the Condensed Consolidated Balance Sheets at their gross fair value.

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 six months ended June 30, 2022 or 2021.

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 in the financial statements. 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:

	Carrying Amount		Fair value as of June 30, 2022								Carrying Amount		Fair value as of December 31, 2021
$ in millions			Level 1		Level 2		Level 3		Total				Level 1		Level 2		Level 3		Total

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

We previously entered into interest rate derivative contracts to manage interest rate exposure related to anticipated borrowings of fixed-rate debt. These interest rate derivative contracts were settled in 2013, and we continue to amortize amounts out of AOCL into interest expense.

The following tables provide information concerning gains recognized in AOCL for the cash flow hedges for the three and six months ended June 30, 2022 and 2021:

Significant transactions

On June 1, 2022, AES Ohio re-issued $140.0 million of tax-exempt Ohio Air Quality Development Authority (OAQDA) Collateralized Pollution Revenue Refunding Bonds that had been held in trust, Series 2015A&B. AES Ohio re-issued $140.0 million aggregate principal amount of first mortgage bonds to the OAQDA in two series: $100.0 million Series 2015A bonds at an interest rate of 4.25% and $40.0 million Series 2015B at an interest rate of 4.00% to secure the loan of proceeds from these bonds issued by the OAQDA. These bonds are subject to a mandatory put date of June 1, 2027.

DPL agreed to register the 2025 DPL Inc. Senior Unsecured Bonds under the Securities Act by filing an exchange offer registration statement or, under specified circumstances, a shelf registration statement with the SEC pursuant to a Registration Rights Agreement dated June 19, 2020. DPL filed a registration statement on Form S-4 with respect to the 2025 DPL Inc. Senior Unsecured Bonds with the SEC on March 15, 2021, and this registration statement was declared effective on March 31, 2021. The exchange offer closed on May 5, 2021.

Long-term debt covenants and restrictions

The DPL Credit Agreement has two financial covenants. The first financial covenant, a minimum EBITDA, calculated at the end of each fiscal quarter for the four prior fiscal quarters of $125.0 million is required, stepping up to $130.0 million on September 30, 2022 and $150.0 million on December 31, 2022. As of June 30, 2022, DPL was in compliance with this financial covenant.

The second financial covenant is an EBITDA to Interest Expense ratio that is calculated, at the end of each fiscal quarter, by dividing EBITDA for the four prior fiscal quarters by the consolidated interest charges for the same period. The ratio, per the agreement, is to be not less than 1.70 to 1.00, and steps up to 1.75 to 1.00 on September

20

Table of Contents

30, 2022 and 2.00 to 1.00 as of December 31, 2022. As of June 30, 2022, DPL was in compliance with this financial covenant.

The DPL Credit Agreement also restricts dividend payments from DPL to AES, such that DPL cannot make dividend payments unless at the time of, and/or as a result of the distribution, (i) DPL’s leverage ratio does not exceed 0.67 to 1.00 and DPL’s interest coverage ratio is not less than 2.50 to 1.00 or, if such ratios are not within the parameters, (ii) DPL’s senior long-term debt rating from two of the three major credit rating agencies is at least investment grade. As a result, as of June 30, 2022, DPL was prohibited from making a distribution to its shareholder or making a loan to any of its affiliates (other than its subsidiaries).

Starting with the quarter ended September 30, 2021, the borrowing limit on the DPL Credit Agreement will be reduced by $5.0 million per quarter should the Total Debt to EBITDA ratio for the period of four consecutive quarters exceed 7.00 to 1.00. As of June 30, 2022, DPL exceeded this ratio and the borrowing limit was reduced from $95.0 million to $90.0 million.

The AES Ohio Credit Agreement and Bond Purchase Agreement (financing document entered into in connection with the issuance of AES Ohio's First Mortgage Bonds, on July 31, 2020) has 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 June 30, 2022, AES Ohio was in compliance with this financial covenant.

As of June 30, 2022, DPL and AES Ohio were in compliance with all debt covenants, including the financial covenants 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.

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 133.3% and (40.5)% for the three and six months ended June 30, 2022, respectively, as compared to 69.2% and 2.8% for the three and six months ended June 30, 2021, respectively. The year-to-date rate is different from the combined federal and state statutory rate of 22.1% 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.

DPL's income tax expense for the six months ended June 30, 2022 was calculated using the estimated annual effective income tax rate for 2022 of (43.8)% on ordinary income. Management estimates the annual effective tax rate based on its forecast of annual pre-tax income or loss.

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

AES Ohio sponsors a defined benefit pension plan for the majority of its employees.

We generally fund pension plan benefits as accrued in accordance with the minimum funding requirements of ERISA and, in addition, make voluntary contributions from time to time. There were $7.5 million and $9.8 million in employer contributions during the six months ended June 30, 2022 and 2021, respectively.

The amounts presented in the following tables for pension include the collective bargaining plan formula, the traditional management plan formula, the cash balance plan formula and the SERP, in the aggregate. The pension costs below have not been adjusted for amounts billed to the Service Company for former AES Ohio employees

Table of Contents

who are now employed by the Service Company or other AES affiliates that are still participants in the AES Ohio plan. The components of net periodic benefit costs other than service costs are included in "Other income" in the Condensed Consolidated Statements of Operations.

The net periodic benefit cost of the pension benefit plans for the three and six months ended June 30, 2022 and 2021 was:

	Three months ended				Six months ended
	June 30,				June 30,
$ in millions	2022		2021		2022		2021
Service cost	$	1.2	$	1.1	$	2.5	$	2.2
Interest cost	2.4		2.0		4.8		4.0
Expected return on plan assets	(3.9)		(3.7)		(7.9)		(7.4)
Amortization of unrecognized:
Prior service cost	0.3		0.2		0.5		0.4
Actuarial loss	1.3		2.3		2.7		4.6
Net periodic benefit cost	$	1.3	$	1.9	$	2.6	$	3.8

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

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 of $8.7 million and $8.9 million as of June 30, 2022 and December 31, 2021, respectively, were not material to the financial statements in the periods covered by this report.

8. Commitments and Contingencies

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 June 30, 2022, AES Ohio could be responsible for the repayment of 4.9%, or $53.9 million, of $1,099.9 million OVEC debt obligations if they came due, comprised of both fixed and variable rate securities with maturities from 2022 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.

Contingencies

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 June 30, 2022, cannot be reasonably determined.

Environmental Matters

DPL’s and AES Ohio’s current and previously-owned facilities and operations are subject to a wide range of federal, state and local environmental regulations and laws. The environmental issues that may affect us include:

•The federal CAA and state laws and regulations (including State Implementation Plans) which require compliance, obtaining permits and reporting as to air emissions;

•Litigation with federal and certain state governments and certain special interest groups regarding whether modifications to or maintenance of certain coal-fired generating stations require additional permitting or pollution control technology, or whether emissions from coal-fired generating stations cause or contribute to global climate changes;

22

Table of Contents

•Rules and future rules issued by the EPA, the Ohio EPA or other authorities that require or will require substantial reductions in SO2, particulates, mercury, acid gases, NOx and other air emissions;

•Rules and future rules issued by the EPA, the Ohio EPA or other authorities that require or will require reporting and reductions of GHGs;

•Rules and future rules issued by the EPA, the Ohio EPA or other authorities associated with the federal Clean Water Act, which prohibits the discharge of pollutants into waters of the United States except pursuant to appropriate permits; and

•Solid and hazardous waste laws and regulations, which govern the management and disposal of certain waste. Most of the solid waste created from the combustion of coal and fossil fuels is fly ash and other coal combustion by-products.

In addition to imposing continuing compliance obligations, federal, state and local environmental laws 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 our facilities to comply, or to determine compliance, with such regulations. We record liabilities for loss contingencies related to environmental matters when a loss is probable of occurring and can be reasonably estimated in accordance with the provisions of GAAP. Accordingly, we have immaterial accruals for loss contingencies for environmental matters. We also have several environmental matters for which we have not accrued loss contingencies because the risk of loss is not probable, or a loss cannot be reasonably estimated. We evaluate the potential liability related to environmental matters quarterly and may revise our estimates. Such revisions in the estimates of the potential liabilities could have a material adverse effect on our results of operations, financial condition and cash flows.

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

9. Business Segments

DPL manages its business through one reportable operating segment, the Utility segment. The primary segment performance measure is income / (loss) from continuing operations 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 discussed further below.

Utility Segment

The Utility segment is comprised of AES Ohio’s electric transmission and distribution businesses, which distribute electricity to residential, commercial, industrial and governmental customers. AES Ohio distributes electricity to approximately 535,000 retail customers located in a 6,000-square mile area of West Central 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 recording 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. The Utility segment includes revenues and costs associated with our investment in OVEC.

Included within the “Other” column are other businesses that do not meet the GAAP requirements for disclosure as reportable segments as well as certain corporate costs, which include interest expense on DPL's long-term debt as well as adjustments related to purchase accounting from the Merger. The accounting policies of the reportable segment are the same as those described in Note 1 – Overview and Summary of Significant Accounting Policies of our 10-K. Intersegment sales, costs of sales and expenses are eliminated in consolidation. Certain shared and corporate costs are allocated between "Other" and the Utility reporting segment.

10. 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

The balances of receivables from contracts with customers were $75.7 million and $61.5 million as of June 30, 2022 and December 31, 2021, respectively. Payment terms for all receivables from contracts with customers are typically within 30 days, though, as a result of COVID-19, AES Ohio began offering expanded payment arrangements for customers.

11. Discontinued Operations

Conesville - In May 2020, AEP, the operator of the formerly co-owned Conesville EGU, retired Conesville Unit 4 as planned. On June 5, 2020, DPL and AES Ohio Generation, together with AEP, completed the transfer of their interests in the retired Unit 4, including the associated environmental liabilities, to an unaffiliated third-party purchaser. For the transaction, DPL made quarterly cash expenditures, totaling $4.0 million, through June 2022. The transfer of Conesville Unit 4 was the last step in DPL's plan to exit its AES Ohio Generation business operations.

DPL determined that the transfer of Conesville and the previous transfers and sales of other AES Ohio Generation assets constitute the disposal of a group of components, which, as a whole, represent a strategic shift to exit its

26

Table of Contents

AES Ohio Generation business. As such, the disposal of this group of components qualified to be presented as discontinued operations. Therefore, the results of operations of this group of components have been reported as such in the Condensed Consolidated Statements of Operations for the period indicated below.

The following table summarizes the revenues, operating costs, other expenses and income tax of discontinued operations for the period indicated:

	Three months ended		Six months ended
	June 30,		June 30,
$ in millions	2021		2021
Revenues	$	0.5	$	1.4
Operating costs and other expenses	(0.7)		(2.4)
Loss from discontinued operations before income tax	(0.2)		(1.0)
Income tax benefit from discontinued operations	—		(0.2)
Net loss from discontinued operations	$	(0.2)	$	(0.8)

Cash flows related to discontinued operations are included in our Condensed Consolidated Statements of Cash Flows. For the three and six months ended June 30, 2021, cash flows from operating activities for discontinued operations were $0.2 million and $0.0 million, respectively. For the three and six months ended June 30, 2021, cash flows from investing activities for discontinued operations were $(0.4) million and $(0.8) million, respectively.

12. Risks and Uncertainties

COVID-19 Pandemic

The COVID-19 pandemic has impacted global economic activity, including electricity and energy consumption, and caused significant volatility in financial markets. Social distancing measures designed to slow the spread of the virus, such as business closures and operations limitations, impact energy demand within our service territory. We continue to take a variety of measures in response to the spread of COVID-19 to ensure our ability to transmit, distribute and sell electric energy, ensure the health and safety of our employees, contractors, customers and communities and provide essential services to the communities in which we operate. The magnitude and duration of the COVID-19 pandemic is unknown at this time and may have material and adverse effects on our results of operations, financial condition and cash flows in future periods.

Notes to Unaudited Condensed Financial Statements

For the three and six months ended June 30, 2022 and 2021

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 535,000 customers located in West Central Ohio. Additionally, AES Ohio 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. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. 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 sells its proportional share of energy and capacity from its investment in OVEC into the wholesale market. AES Ohio has one reportable segment, the Utility segment. In addition to AES Ohio's electric transmission and distribution businesses, the Utility segment includes revenues and costs 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.

Financial Statement Presentation

AES Ohio does not have any subsidiaries. Certain immaterial amounts from prior periods have been reclassified to conform to the current period presentation.

Interim Financial Presentation

The accompanying unaudited condensed financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASB ASC, 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, changes in common shareholder's equity, and cash flows. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of expected results for the year ending December 31, 2022. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2021 audited consolidated financial statements and notes 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 revenues and expenses of the periods reported. Actual results could differ from these estimates and assumptions. Significant items subject to such estimates and assumptions include: recognition of revenue including unbilled revenues; the carrying value of property, plant and equipment; 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; and assets and liabilities related to employee benefits.

Total accounts receivable, net	$	84.8	$	71.9

The following table is a roll forward of our allowance for credit losses related to the accounts receivable balances for the six months ended June 30, 2022 and 2021:

$ in millions	Beginning Allowance Balance		Current Period Provision		Write-offs Charged Against Allowances		Recoveries Collected		Ending Allowance Balance
2022	$	0.3	$	0.7	$	(1.1)	$	0.4	$	0.3
2021	$	2.8	$	(0.2)	$	(1.6)	$	0.7	$	1.7

The allowance for credit losses primarily relates to utility customer receivables, including unbilled amounts. Expected credit loss estimates are developed by disaggregating customers into those with similar credit risk characteristics and using historical credit loss experience. In addition, we also consider how current and future economic conditions are expected to impact collectability, as applicable, including the economic impacts of the COVID-19 pandemic on our receivable balance as of June 30, 2022. Amounts are written off when reasonable collections efforts have been exhausted. During 2021, the current period provision and allowance for credit losses decreased due to lower past due customer receivable balances.

Inventories

Inventories consist of materials and supplies as of June 30, 2022 and December 31, 2021.

New Accounting Pronouncements Adopted in 2022

The following table provides a brief description of recent accounting pronouncements that had an impact on our financial statements.

ASU Number and Name	Description	Date of Adoption	Effect on the financial statements upon adoption
2020-04 and 2021-01, Reference Rate Form (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting	The amendments in these updates provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference to LIBOR or another reference rate expected to be discontinued by reference rate reform, and clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. These amendments are effective for a limited period of time (March 12, 2020 - December 31, 2022).	Effective for all entities as of March 12, 2020 through December 31, 2022	We are implementing the reference rate reform and do not expect these amendments to have a material impact on our financial statements. See Implementation for further details.

New Accounting Pronouncements Issued But Not Yet Effective

We have assessed and determined that the new accounting pronouncements issued but not yet effective are not expected to have a material impact on our financial statements.

2. Regulatory Matters

Distribution Rate Case

On November 30, 2020, AES Ohio filed a new distribution rate case with the PUCO. This rate case proposes a revenue increase of $120.8 million per year and incorporates the DIR investments that were planned and approved in the last rate case but not yet included in distribution rates, other distribution investments since September 2015 and investments necessitated by the tornados that occurred on Memorial Day in 2019. The rate case also includes a proposal for increased tree-trimming expenses and certain customer demand-side management programs and recovery of prior-approved regulatory assets for tree trimming, uncollectible expenses and rate case expense. A hearing on this case was held in January 2022, and the case is pending a commission order. Certain parties that have intervened in the distribution rate case have argued that ESP 1 incorporates a distribution rate freeze. Oral arguments regarding the potential rate freeze were held in May 2022. We are unable to predict the outcome of the distribution rate case, but if the PUCO were to impose a rate freeze that precludes AES Ohio’s ability to implement a distribution rate increase during ESP 1, it could have a material adverse effect on our results of operations, financial condition and cash flows.

3. Fair Value

The fair value of current financial assets and liabilities and other deposits approximate 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 and 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 investments are recorded at fair value within Other non-current assets on the Condensed Balance Sheets and classified as equity investments. We recorded net unrealized gains / (losses) of $(0.9) million and $0.3 million during the three months ended June 30, 2022 and 2021, respectively, and $(1.6) million and $0.5 million during the six months ended June 30, 2022 and 2021, respectively. These amounts are included in "Other expense" in our Condensed Statements of Operations.

Recurring Fair Value Measurements

The following table presents the fair value, carrying value and cost of our non-derivative instruments as of June 30, 2022 and December 31, 2021.

	June 30, 2022				December 31, 2021
$ in millions	Cost		Fair Value		Cost		Fair Value

Debt securities	3.7		3.3		3.8		3.9
Total	$	5.9	$	7.5	$	6.1	$	9.4

These financial instruments are not subject to master netting agreements or collateral requirements and, as such, are presented in the Condensed Balance Sheets at their gross fair value.

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 six months ended June 30, 2022 or 2021.

The fair value of assets and liabilities as of June 30, 2022 and December 31, 2021 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 in the financial statements. The long-term debt amounts include the current portion payable in the next twelve months and have maturities that range from 2025 to 2061.

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

Line of credit

As of June 30, 2022 and December 31, 2021, the AES Ohio Credit Agreement had outstanding borrowings on its line of credit of $0.0 million and $0.0 million, respectively.

Significant transactions

On June 1, 2022, AES Ohio re-issued $140.0 million of tax-exempt Ohio Air Quality Development Authority (OAQDA) Collateralized Pollution Revenue Refunding Bonds that had been held in trust, Series 2015A&B. AES Ohio re-issued $140.0 million aggregate principal amount of first mortgage bonds to the OAQDA in two series: $100.0 million Series 2015A bonds at an interest rate of 4.25% and $40.0 million Series 2015B at an interest rate of 4.00% to secure the loan of proceeds from these bonds issued by the OAQDA. These bonds are subject to a mandatory put date of June 1, 2027.

Long-term debt covenants and restrictions

The AES Ohio Credit Agreement and Bond Purchase Agreement (financing document entered into in connection with the issuance of AES Ohio's First Mortgage Bonds, on July 31, 2020) has 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 June 30, 2022, AES Ohio was in compliance with this financial covenant.

As of June 30, 2022, AES Ohio was in compliance with all debt covenants, including the financial covenants 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.

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 0.0% and 10.0% for the three and six months ended June 30, 2022, respectively, as compared to 5.5% and 12.1% for the three and six months ended June 30, 2021, respectively. The year-to-date rate is different from the combined federal and state statutory rate of 22.1% 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.

AES files federal and state income tax returns which consolidates 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

AES Ohio sponsors a defined benefit pension plan for the majority of its employees.

We generally fund pension plan benefits as accrued in accordance with the minimum funding requirements of ERISA and, in addition, make voluntary contributions from time to time. There were $7.5 million and $9.8 million in employer contributions during the six months ended June 30, 2022 and 2021, respectively.

The amounts presented in the following tables for pension include the collective bargaining plan formula, the traditional management plan formula, the cash balance plan formula and the SERP, in the aggregate. 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 plan. The components of net periodic benefit costs other than service costs are included in "Other expense" in the Condensed Statements of Operations.

The net periodic benefit cost of the pension benefit plans for the three and six months ended June 30, 2022 and 2021 was:

	Three months ended				Six months ended
	June 30,				June 30,
$ in millions	2022		2021		2022		2021
Service cost	$	1.2	$	1.1	$	2.5	$	2.2
Interest cost	2.4		2.0		4.8		4.0
Expected return on plan assets	(3.9)		(3.7)		(7.9)		(7.4)
Amortization of unrecognized:
Prior service cost	0.3		0.3		0.6		0.6
Actuarial loss	1.9		2.8		3.8		5.6
Net periodic benefit cost	$	1.9	$	2.5	$	3.8	$	5.0

.

The components of net periodic (benefit) / cost other than service cost are included in "Other expense" in the Condensed Statements of Operations.

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 of $8.7 million and $8.9 million as of June 30, 2022 and December 31, 2021, respectively, were not material to the financial statements in the periods covered by this report.

7. Commitments and Contingencies

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,

39

Table of Contents

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 June 30, 2022, AES Ohio could be responsible for the repayment of 4.9%, or $53.9 million, of $1,099.9 million OVEC debt obligations if they came due, comprised of both fixed and variable rate securities with maturities from 2022 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.

Contingencies

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 June 30, 2022, cannot be reasonably determined.

Environmental Matters

AES Ohio’s current and previously-owned facilities and operations are subject to a wide range of federal, state and local environmental regulations and laws. The environmental issues that may affect us include:

•The federal CAA and state laws and regulations (including State Implementation Plans) which require compliance, obtaining permits and reporting as to air emissions;

•Litigation with federal and certain state governments and certain special interest groups regarding whether modifications to or maintenance of certain coal-fired generating stations require additional permitting or pollution control technology, or whether emissions from coal-fired generating stations cause or contribute to global climate changes;

•Rules and future rules issued by the EPA, the Ohio EPA or other authorities that require or will require substantial reductions in SO2, particulates, mercury, acid gases, NOx and other air emissions;

•Rules and future rules issued by the EPA, the Ohio EPA or other authorities that require or will require reporting and reductions of GHGs;

•Rules and future rules issued by the EPA, the Ohio EPA or other authorities associated with the federal Clean Water Act, which prohibits the discharge of pollutants into waters of the United States except pursuant to appropriate permits; and

•Solid and hazardous waste laws and regulations, which govern the management and disposal of certain waste.

In addition to imposing continuing compliance obligations, federal, state and local environmental laws 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 our facilities to comply, or to determine compliance, with such regulations. We record liabilities for loss contingencies related to environmental matters when a loss is probable of occurring and can be reasonably estimated in accordance with the provisions of GAAP. Accordingly, we have immaterial accruals for loss contingencies for environmental matters. We also have several environmental matters for which we have not accrued loss contingencies because the risk of loss is not probable, or a loss cannot be reasonably estimated. We evaluate the potential liability related to environmental matters quarterly and may revise our estimates. Such revisions in the estimates of the potential liabilities could have a material adverse effect on our results of operations, financial condition and cash flows.

8. 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 revenues, see Note 12 — Revenue in Item 8.—Financial Statements and Supplementary Data of our Form 10-K.

The balances of receivables from contracts with customers were $74.5 million and $60.8 million as of June 30, 2022 and December 31, 2021, respectively. Payment terms for all receivables from contracts with customers are typically within 30 days, though, as a result of COVID-19, AES Ohio began offering expanded payment arrangements for customers.

9. Risks and Uncertainties

COVID-19 Pandemic

The COVID-19 pandemic has impacted global economic activity, including electricity and energy consumption, and caused significant volatility in financial markets. Social distancing measures designed to slow the spread of the virus, such as business closures and operations limitations, impact energy demand within our service territory. We continue to take a variety of measures in response to the spread of COVID-19 to ensure our ability to transmit, distribute and sell electric energy, ensure the health and safety of our employees, contractors, customers and communities and provide essential services to the communities in which we operate. The magnitude and duration of the COVID-19 pandemic is unknown at this time and may have material and adverse effects on our results of operations, financial condition and cash flows in future periods.

DPL – Revenues

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 revenues are affected by

(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 six months ended June 30, 2022, Depreciation and amortization increased $1.2 million and $1.6 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 six months ended June 30, 2022, Taxes other than income taxes increased $0.5 million and $2.1 million, respectively, compared to the same periods in the prior year. The increases were primarily the result of higher property taxes due to higher assessed values in the current year.

DPL – Income Tax Expense / (Benefit) From Continuing Operations

Income tax benefit was $0.8 million during the three months ended June 30, 2022 compared to income tax expense of $0.9 million during the three months ended June 30, 2021. The change was primarily due to a loss from continuing operations before income tax in the current period as compared to income from continuing operations before income tax in the same period in the prior year.

Income tax benefit was $4.5 million during the six months ended June 30, 2022 compared to income tax expense of $0.6 million during the six months ended June 30, 2021. The change was primarily due to a lower estimated effective tax rate in the current year versus the prior year as a result of the reversal of excess deferred items as a percentage of pre-tax book income.

See Note 6 – Income Taxes in the Notes to 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) from continuing operations 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 discussed further below.

Utility Segment

The Utility segment is comprised of AES Ohio’s electric transmission and distribution businesses, which distribute electricity to residential, commercial, industrial and governmental customers. AES Ohio distributes electricity to approximately 535,000 retail customers located in a 6,000-square mile area of West Central 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 recording regulatory assets when incurred costs are expected to be recovered in future

Table of Contents

customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs. The Utility segment includes revenues and costs associated with our investment in OVEC.

Included within the “Other” column are other businesses that do not meet the GAAP requirements for disclosure as reportable segments as well as certain corporate costs, which include interest expense on DPL's long-term debt as well as adjustments related to purchase accounting from the Merger. The accounting policies of the reportable segment are the same as those described in Note 1 – Overview and Summary of Significant Accounting Policies of our 10-K. Intersegment sales, costs of sales and expenses are eliminated in consolidation. Certain shared and corporate costs are allocated between "Other" and the Utility reporting segment.

See Part I, Item 1, Note 9 – Business Segments of Notes to DPL's Condensed Consolidated Financial Statements for additional information regarding DPL’s reportable segment.

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

AES Ohio – Revenues

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 revenues are 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 Notes to AES Ohio's Condensed Financial Statements.

During the three and six months ended June 30, 2022, Depreciation and amortization increased $1.2 million and $1.7 million, respectively, compared to the same periods in the prior year primarily due to additional assets placed in service.

AES Ohio – Taxes Other Than Income Taxes

During the three and six months ended June 30, 2022, Taxes other than income taxes increased $0.4 million and $2.0 million, respectively, compared to the same periods in the prior year. The increases were primarily the result of higher property taxes due to higher assessed values in the current year.

AES Ohio – Income Tax Expense

During the three and six months ended June 30, 2022, Income tax expense decreased $0.5 million and $1.0 million, respectively, compared to the same periods in the prior year primarily due to a decrease in the effective tax rate and lower income before income tax in the current year.

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

KEY TRENDS AND UNCERTAINTIES

During 2022 and beyond, we expect our financial results will be primarily impacted by retail demand and weather. As discussed in Note 2 – Regulatory Matters of Notes to DPL's Condensed Consolidated Financial Statements and Note 2 – Regulatory Matters of Notes to AES Ohio's Condensed Financial Statements in Part I, Item 1 of this report, AES Ohio has requested PUCO approval to defer its decoupling costs consistent with the methodology approved in its distribution rate order. If approved, the deferral would be effective as of December 18, 2019 and going forward would reduce impacts of weather, energy efficiency programs and economic changes in customer demand until its pending distribution rates are in effect. 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.

Operational

COVID-19 Pandemic - The COVID-19 pandemic has impacted global economic activity, including electricity and energy consumption, and caused significant volatility in financial markets. Throughout the COVID-19 pandemic we have conducted our essential operations without significant disruption. We are taking a variety of measures to ensure our ability to transmit, distribute and sell electric energy, to ensure the health and safety of our employees, contractors, customers and communities and to provide essential services to the communities in which we operate.

52

Table of Contents

The COVID-19 pandemic primarily impacted our retail sales demand. Retail sales demand decreased in 2020 mostly from commercial and industrial customers but has recovered. While we have continued to experience some COVID-19 impacts into 2022, such impacts have not been material nor do we expect they will be material, particularly if reduced social distancing measures and improvements in energy demand continue. The magnitude and duration of the COVID-19 pandemic is unknown at this time, however, and could have material and adverse effects on our results of operations, financial condition and cash flows in future periods. Also see Item 1A.—Risk Factors of our Form 10-K.

We have not had nor do we expect to have a significant impact to our access to capital or our liquidity position as a result of the COVID-19 pandemic. We also have not experienced any material credit-related impacts due to the COVID-19 pandemic, but continue to monitor and manage our credit exposures in a prudent manner.

Capital Projects - Our construction projects have experienced some indications of delays and price increases; 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

Reference Rate Reform - As discussed in Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations, of our Form 10-K, in July 2017, the UK Financial Conduct Authority announced that it intended to phase out LIBOR by the end of 2021. In the U.S., the Alternative Reference Rate Committee at the Federal Reserve identified the Secured Overnight Financing Rate ("SOFR") as its preferred alternative rate for LIBOR; alternative reference rates in other key markets are under development. The ICE Benchmark Association has determined that it will cease publication of the one-month, three-month, six-month, and 12-month USD LIBOR rates by June 30, 2023. We hold debt that references LIBOR as an interest rate benchmark. In order to facilitate an organized transition from LIBOR to alternative benchmark rate(s), we have established a process to measure and mitigate risks associated with the cessation of LIBOR. As part of this initiative, alternative benchmark rates have been, and continue to be, assessed, and implemented for newly executed agreements. Many of our existing agreements include provisions designed to facilitate an orderly transition from LIBOR. To the extent that the terms of the credit agreements do not align following the cessation of LIBOR rates, we will seek to negotiate contract amendments with counterparties.

U.S. Income Tax - The macroeconomic and political environments in the U.S. have changed during 2021 and 2022. This could result in significant impacts to tax law. For example, in the first quarter of 2022, the Biden Administration released its fiscal year 2023 budget, which includes proposed U.S. corporate tax reform proposals that would increase the U.S. corporate income tax rate. Additional details regarding these potential changes in law are expected to be made available later this year.

Inflation - In the markets in which we operate, there have been higher rates of inflation in recent months. If inflation continues to increase in our markets, 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 standard service offer auction process has reflected current macroeconomic conditions in terms of pricing.

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 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 Form 10-K and Form 10-Q previously filed with the SEC during 2022 describe other regulatory matters which have not materially changed since those filings. See Part I, Item 1, Note 2 – Regulatory Matters of Notes to DPL's Condensed Consolidated Financial Statements and Part I, Item 1, Note 2 – Regulatory Matters of Notes to AES Ohio's Condensed Financial Statements for further information regarding regulatory matters.

Distribution Rate Case - On November 30, 2020, AES Ohio filed a new distribution rate case with the PUCO. Certain parties that have intervened in the distribution rate case have argued that ESP 1 incorporates a distribution rate freeze. We are unable to predict the outcome of the distribution rate case, but if the PUCO were to impose a rate freeze that precludes AES Ohio’s ability to implement a distribution rate increase during ESP 1, it could have a material adverse effect on our results of operations, financial condition and cash flows.

Environmental

In addition to imposing continuing compliance obligations, federal, state and local environmental laws 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 our facilities to comply, or to determine compliance, with such regulations. We record liabilities for loss contingencies related to environmental matters when a loss is probable of occurring and can be reasonably estimated in accordance with the provisions of GAAP. Accordingly, we have immaterial accruals for loss contingencies for environmental matters. We also have several environmental matters for which we have not accrued loss contingencies because the risk of loss is not probable, or a loss cannot be reasonably estimated. We evaluate the potential liability related to environmental matters quarterly and may revise our estimates. Such revisions in the estimates of the potential liabilities could have a material adverse effect on our results of operations, financial condition and cash flows. We refer to the discussion in “Item 1. Business - Environmental Matters” in our 2021 Form 10-K for a discussion of certain recent developments in environmental laws and regulations.

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’s retirement and subsequent sale of its Stuart and Killen generating stations, the sale of its ownership interest in the Miami Fort and Zimmer generating stations and the retirement and subsequent sale of Conesville, 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

•potential Clean Air Act 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 February 20, 2020, the EPA published a proposed rule to establish a federal CCR permit program that would operate in states without approved CCR permit programs. The EPA has indicated that they will implement a phased approach to amending the CCR rule, which is ongoing. With the sale of our coal-fired generating stations, we expect that the impact of these regulations would be limited to our interest in OVEC. The CCR Rule, current or proposed amendments to 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.

On August 28, 2020, the EPA published the CCR Part A Rule that, among other amendments, required certain CCR units to cease waste receipt and initiate closure by April 11, 2021. The CCR Part A Rule also allowed for extensions of the April 11, 2021 deadline if EPA determines certain criteria are met. Facilities seeking such an extension were required to submit a demonstration to EPA by November 30, 2020. On January 11, 2022, EPA released pre-publication versions of proposed determinations regarding nine CCR Part A Rule demonstrations, including for OVEC’s Clifty Creek. On the same day, EPA issued four compliance-related letters notifying certain other facilities of their compliance obligations under the federal CCR regulations. The determinations and letters include interpretations regarding implementation of the CCR Rule. On April 8, 2022, petitions for review were filed challenging these EPA actions. The petitions are consolidated in Electric Energy, Inc. v. EPA. On July 12, 2022, the EPA released prepublication determinations regarding two CCR Part A Rule demonstrations. It is too early to determine the direct or indirect impact of these letters or any determinations that may be made.

CAPITAL RESOURCES AND LIQUIDITY

DPL and AES Ohio had unrestricted cash and cash equivalents of $60.3 million and $44.9 million, respectively, as of June 30, 2022. 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 $1,552.7 million and $722.1 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.

On June 1, 2022, AES Ohio re-issued $140.0 million of tax-exempt Ohio Air Quality Development Authority (OAQDA) Collateralized Pollution Revenue Refunding Bonds that had been held in trust, Series 2015A&B. AES Ohio re-issued $140.0 million aggregate principal amount of first mortgage bonds to the OAQDA in two series: $100.0 million Series 2015A bonds at an interest rate of 4.25% and $40.0 million Series 2015B at an interest rate of 4.00% to secure the loan of proceeds from these bonds issued by the OAQDA. These bonds are subject to a mandatory put date of June 1, 2027.

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 sources of liquidity to remain sufficient to meet our anticipated operating needs. Our business is capital intensive, requiring significant resources to fund operating expenses, construction expenditures, scheduled debt maturities and carrying costs, taxes and dividend payments. For 2022 and subsequent years, we expect to satisfy these requirements with cash from operations, funds from debt financing and/or equity capital contributions as our internal liquidity needs and market conditions warrant. We also expect that the borrowing capacity under bank credit facilities will continue to be available to manage working capital requirements during those periods.

At June 30, 2022, AES Ohio and DPL have access to the following revolving credit facilities:

$ in millions	Type	Maturity	Commitment		Amounts available as of June 30, 2022
AES Ohio	Revolving	June 2024	$	175.0	$	175.0
DPL	Revolving	June 2023	90.0		40.0
			$	265.0	$	215.0

The AES Ohio Credit Agreement is an unsecured revolving credit facility with a syndicated bank group with a borrowing limit of $175.0 million and a $75.0 million letter of credit sublimit, as well as a feature that provides AES Ohio the ability to increase the size of the facility by an additional $100.0 million. This facility expires in June 2024. As of June 30, 2022, there were $0.0 million in borrowings under the facility, with the remaining $175.0 million available to AES Ohio.

The DPL Credit Agreement is a secured revolving credit facility with a syndicated bank group with a borrowing limit of $90.0 million, with a $75.0 million letter of credit sublimit and a feature that provides DPL the ability to increase the size of the facility by an additional $50.0 million. This facility is secured by a pledge of common stock that DPL owns in AES Ohio. The facility expires in June 2023. As of June 30, 2022, there were no letter of credits outstanding and $50.0 million in borrowings, with the remaining $40.0 million available to DPL.

(a)    AES Ohio's investments in distribution-related additions, improvements and extensions are dependent on favorable regulatory outcomes.

AES Ohio's projection includes expected spending under its Smart Grid Plan included in the comprehensive settlement approved by the PUCO on June 16, 2021, as well as new transmission projects. See additional information in Note 2 – Regulatory Matters of Notes to DPL's Condensed Consolidated Financial Statements and Note 2 – Regulatory Matters of Notes to 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. AES Ohio anticipates spending approximately $76.0 million within the next five years to reinforce its transmission system to comply with mandatory NERC and FERC Form 715 planning requirements. These anticipated costs are included in the overall capital projections above.

Off-Balance Sheet Arrangements

For information on guarantees, commercial commitments, and contractual obligations, see Part I, Item 1, Note 8 – Commitments and Contingencies of Notes to DPL's Condensed Consolidated Financial Statements and Part I, Item 1, Note 7 – Commitments and Contingencies of Notes to 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, revenues, 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 revenues; 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, 2021 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 six months ended June 30, 2022.

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 June 30, 2022, 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 — There were no changes that occurred during the fiscal quarter covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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, 2021 and Form 10-Q for the quarter ended March 31, 2022, 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 – Regulatory Matters of Notes to DPL's Condensed Consolidated Financial Statements and Part I, Item 1, Note 2 – Regulatory Matters of Notes to AES Ohio's Condensed Financial Statements of this Quarterly Report on Form 10-Q.

Item 1A – Risk Factors

A listing of the risk factors that we consider to be the most significant to a decision to invest in our securities is provided in our Form 10-K. Except as described below, there has been no material change in our risk factors as previously disclosed in our Form 10-K. If any of the events described in our risk factors occur, it could have a material adverse effect on our results of operations, financial condition and cash flows.

The risks and uncertainties described in our risk factors are not the only ones we face. In addition, new risks may emerge at any time, and we cannot predict those risks or estimate the extent to which they may affect our business or financial performance. Our risk factors should be read in conjunction with the other detailed information concerning DPL and AES Ohio set forth in the Notes to DPL’s and AES Ohio’s Financial Statements found in Part I, Item 1, and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections included in our filings.

As part of the filing of this Quarterly Report on Form 10-Q, we are further revising, clarifying and

supplementing a risk factor from our Form 10-K. The risk factor below should be considered together with the other risk factors described in our Form 10-K:

Potential security breaches (including cybersecurity breaches) and terrorism risks could materially and adversely affect our businesses.

We operate in a highly regulated industry that requires the continued operation of sophisticated systems and network infrastructure at our transmission, distribution and other facilities. We also use various financial, accounting and other systems in our businesses. These systems and facilities are vulnerable to unauthorized access due to hacking, viruses, other cybersecurity attacks and other causes. In particular, given the importance of energy and the electric grid, there is the possibility that our systems and facilities could be targets of terrorism or acts of war, and there has been an increased focus on the U.S. energy grid that is believed to be related to the Russia/Ukraine conflict. We have implemented measures to help prevent unauthorized access to our systems and facilities, including network and system monitoring, identification and deployment of secure technologies and certain other

60

Table of Contents

measures to comply with mandatory regulatory reliability standards. Pursuant to NERC requirements, we have a robust cybersecurity plan in place and are subject to regular audits by an independent auditor approved by the NERC. We routinely test our systems and facilities against these regulatory requirements in order to measure compliance, assess potential security risks and identify areas for improvement. In addition, we provide cybersecurity training for our employees and perform exercises designed to raise employee awareness of cyber risks on a regular basis. To date, cyber-attacks on our business and operations have not had a material impact on our operations or financial results. Despite these efforts, if our systems or facilities were to be breached or disabled, we may be unable to recover them in a timely manner to fulfill critical business functions, including the supply of electric services to our customers, and we could experience decreases in revenues and increases in costs that could materially and adversely affect our results of operations, financial condition and cash flows

In the course of our business, we also store and use customer, employee and other personal information and other confidential and sensitive information, including personally identifiable information and personal financial information. If our or our third-party vendors’ systems were to be breached or disabled, sensitive and confidential information and other data could be compromised, which could result in negative publicity, remediation costs and potential litigation, damages, consent orders, injunctions, fines and other relief.

To help mitigate these risks, we maintain insurance coverage against some, but not all, potential losses, including coverage for illegal acts against us. However, insurance may not be adequate to protect us against all costs and liabilities associated with these risks.

Overview and Summary of Significant Accounting Policies

Overview and Summary of Significant Accounting Policies

DPL is a regional energy company organized in 1985 under the laws of Ohio. DPL has one reportable segment, the Utility segment. See Note 9 – Business Segments for more information relating to this reportable segment. The terms “we,” “us,” “our” and “ours” are used to refer to DPL and its subsidiaries.

DPL is an indirectly wholly-owned subsidiary of AES. DP&L, a wholly-owned subsidiary of DPL that 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 535,000 customers located in West Central Ohio. Additionally, AES Ohio 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. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. 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 sells its proportional share of energy and capacity from its investment in OVEC into the wholesale market.

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. In prior periods, AES Ohio Generation was also a primary subsidiary and sold all of its energy and capacity into the wholesale market. AES Ohio Generation retired its only remaining operating asset in May 2020 and sold it in June 2020. See Note 11 – Discontinued Operations for more information. 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.

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.

Certain immaterial amounts from prior periods have been reclassified to conform to the current period presentation. All material intercompany accounts and transactions are eliminated in consolidation.

Interim Financial Presentation

The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASB ASC, 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, changes in common shareholder's deficit, and cash flows. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of expected results for the year ending December 31, 2022. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2021 audited consolidated financial statements and notes 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 revenues and expenses of the periods reported. Actual results could differ from these estimates and assumptions.

Significant items subject to such estimates and assumptions include: recognition of revenue including unbilled revenues; the carrying value of property, plant and equipment; 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; and assets and liabilities related to employee benefits.

Cash, Cash Equivalents and Restricted Cash

The following table summarizes cash, cash equivalents, and restricted cash amounts reported on the Condensed Consolidated Balance Sheets that reconcile to the total of such amounts as shown on the Condensed Consolidated Statements of Cash Flows:

$ in millions	June 30, 2022		December 31, 2021
Cash and cash equivalents	$	60.3	$	26.6
Restricted cash (included in Prepayments and other current assets)	0.1		0.1
Cash, Cash Equivalents, and Restricted Cash, End of Period	$	60.4	$	26.7

Accounts Receivable and Allowance for Credit Losses

The following table summarizes accounts receivable as of June 30, 2022 and December 31, 2021:

	June 30,		December 31,
$ in millions	2022		2021
Accounts receivable, net:
Customer receivables	$	56.9	$	42.3
Unbilled revenue	18.8		19.2
Amounts due from affiliates	4.5		3.1
Due from PJM transmission enhancement settlement	1.7		1.7
Other	3.5		5.5
Allowance for credit losses	(0.3)		(0.3)
Total accounts receivable, net	$	85.1	$	71.5

The following table is a roll forward of our allowance for credit losses related to the accounts receivable balances for the six months ended June 30, 2022 and 2021:

$ in millions	Beginning Allowance Balance		Current Period Provision		Write-offs Charged Against Allowances		Recoveries Collected		Ending Allowance Balance
2022	$	0.3	$	0.7	$	(1.1)	$	0.4	$	0.3
2021	$	2.8	$	(0.2)	$	(1.6)	$	0.7	$	1.7

The allowance for credit losses primarily relates to utility customer receivables, including unbilled amounts. Expected credit loss estimates are developed by disaggregating customers into those with similar credit risk characteristics and using historical credit loss experience. In addition, we also consider how current and future economic conditions are expected to impact collectability, as applicable, including the economic impacts of the COVID-19 pandemic on our receivable balance as of June 30, 2022. Amounts are written off when reasonable collections efforts have been exhausted. During 2021, the current period provision and allowance for credit losses decreased due to lower past due customer receivable balances.

Inventories

Inventories consist of materials and supplies as of June 30, 2022 and December 31, 2021.

Accumulated other comprehensive loss

The amounts reclassified out of Accumulated other comprehensive loss by component during the three and six months ended June 30, 2022 and 2021 are as follows:

AES Ohio collects certain excise taxes levied by state or local governments from its customers. These taxes are accounted for on a net basis and not included in revenue. The amounts of such taxes collected for the three and six months ended June 30, 2022 and 2021 were as follows:

	Three months ended				Six months ended
	June 30,				June 30,

Significant items subject to such estimates and assumptions include: recognition of revenue including unbilled revenues; the carrying value of property, plant and equipment; 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; and assets and liabilities related to employee benefits.

Cash, Cash Equivalents and Restricted Cash

The following table summarizes cash, cash equivalents, and restricted cash amounts reported on the Condensed Balance Sheets that reconcile to the total of such amounts as shown on the Condensed Statements of Cash Flows:

$ in millions	June 30, 2022		December 31, 2021
Cash and cash equivalents	$	44.9	$	14.4
Restricted cash (included in Prepayments and other current assets)	0.1		0.1
Cash, Cash Equivalents, and Restricted Cash, End of Period	$	45.0	$	14.5

Accounts Receivable and Allowance for Credit Losses

The following table summarizes accounts receivable as of June 30, 2022 and December 31, 2021:

	June 30,		December 31,
$ in millions	2022		2021
Accounts receivable, net:
Customer receivables	55.7		$	41.6
Unbilled revenue	18.8		19.2
Amounts due from affiliates	5.5		4.4
Due from PJM transmission enhancement settlement	1.7		1.7
Other	3.4		5.3
Allowance for credit losses	(0.3)		(0.3)
Total accounts receivable, net	$	84.8	$	71.9

The following table is a roll forward of our allowance for credit losses related to the accounts receivable balances for the six months ended June 30, 2022 and 2021:

$ in millions	Beginning Allowance Balance		Current Period Provision		Write-offs Charged Against Allowances		Recoveries Collected		Ending Allowance Balance
2022	$	0.3	$	0.7	$	(1.1)	$	0.4	$	0.3
2021	$	2.8	$	(0.2)	$	(1.6)	$	0.7	$	1.7

The allowance for credit losses primarily relates to utility customer receivables, including unbilled amounts. Expected credit loss estimates are developed by disaggregating customers into those with similar credit risk characteristics and using historical credit loss experience. In addition, we also consider how current and future economic conditions are expected to impact collectability, as applicable, including the economic impacts of the COVID-19 pandemic on our receivable balance as of June 30, 2022. Amounts are written off when reasonable collections efforts have been exhausted. During 2021, the current period provision and allowance for credit losses decreased due to lower past due customer receivable balances.

Distribution Rate Case

On November 30, 2020, AES Ohio filed a new distribution rate case with the PUCO. This rate case proposes a revenue increase of $120.8 million per year and incorporates the DIR investments that were planned and approved in the last rate case but not yet included in distribution rates, other distribution investments since September 2015 and investments necessitated by the tornados that occurred on Memorial Day in 2019. The rate case also includes a proposal for increased tree-trimming expenses and certain customer demand-side management programs and recovery of prior-approved regulatory assets for tree trimming, uncollectible expenses and rate case expense. A hearing on this case was held in January 2022, and the case is pending a commission order. Certain parties that have intervened in the distribution rate case have argued that ESP 1 incorporates a distribution rate freeze. Oral arguments regarding the potential rate freeze were held in May 2022. We are unable to predict the outcome of the distribution rate case, but if the PUCO were to impose a rate freeze that precludes AES Ohio’s ability to implement a distribution rate increase during ESP 1, it could have a material adverse effect on our results of operations, financial condition and cash flows.

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

Fair Value

Fair Value

The fair value of current financial assets and liabilities and other deposits approximate 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 and 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 investments are recorded at fair value within Other non-current assets on the Condensed Consolidated Balance Sheets and classified as equity investments. We recorded net unrealized gains / (losses) of $(0.9) million and $0.3 million during the three months ended June 30, 2022 and 2021, respectively, and $(1.6) million and $0.5 million during the six months ended June 30, 2022 and 2021, respectively. These amounts are included in "Other income" in our Condensed Consolidated Statements of Operations.

Recurring Fair Value Measurements

The following table presents the fair value, carrying value and cost of our non-derivative instruments as of June 30, 2022 and December 31, 2021.

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 in the financial statements. The long-term debt amounts include the current portion payable in the next twelve months and have maturities that range from 2025 to 2061.

DPL agreed to register the 2025 DPL Inc. Senior Unsecured Bonds under the Securities Act by filing an exchange offer registration statement or, under specified circumstances, a shelf registration statement with the SEC pursuant to a Registration Rights Agreement dated June 19, 2020. DPL filed a registration statement on Form S-4 with respect to the 2025 DPL Inc. Senior Unsecured Bonds with the SEC on March 15, 2021, and this registration statement was declared effective on March 31, 2021. The exchange offer closed on May 5, 2021.

Long-term debt covenants and restrictions

The DPL Credit Agreement has two financial covenants. The first financial covenant, a minimum EBITDA, calculated at the end of each fiscal quarter for the four prior fiscal quarters of $125.0 million is required, stepping up to $130.0 million on September 30, 2022 and $150.0 million on December 31, 2022. As of June 30, 2022, DPL was in compliance with this financial covenant.

The second financial covenant is an EBITDA to Interest Expense ratio that is calculated, at the end of each fiscal quarter, by dividing EBITDA for the four prior fiscal quarters by the consolidated interest charges for the same period. The ratio, per the agreement, is to be not less than 1.70 to 1.00, and steps up to 1.75 to 1.00 on September

30, 2022 and 2.00 to 1.00 as of December 31, 2022. As of June 30, 2022, DPL was in compliance with this financial covenant.

The DPL Credit Agreement also restricts dividend payments from DPL to AES, such that DPL cannot make dividend payments unless at the time of, and/or as a result of the distribution, (i) DPL’s leverage ratio does not exceed 0.67 to 1.00 and DPL’s interest coverage ratio is not less than 2.50 to 1.00 or, if such ratios are not within the parameters, (ii) DPL’s senior long-term debt rating from two of the three major credit rating agencies is at least investment grade. As a result, as of June 30, 2022, DPL was prohibited from making a distribution to its shareholder or making a loan to any of its affiliates (other than its subsidiaries).

Starting with the quarter ended September 30, 2021, the borrowing limit on the DPL Credit Agreement will be reduced by $5.0 million per quarter should the Total Debt to EBITDA ratio for the period of four consecutive quarters exceed 7.00 to 1.00. As of June 30, 2022, DPL exceeded this ratio and the borrowing limit was reduced from $95.0 million to $90.0 million.

The AES Ohio Credit Agreement and Bond Purchase Agreement (financing document entered into in connection with the issuance of AES Ohio's First Mortgage Bonds, on July 31, 2020) has 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 June 30, 2022, AES Ohio was in compliance with this financial covenant.

As of June 30, 2022, DPL and AES Ohio were in compliance with all debt covenants, including the financial covenants 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.

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 133.3% and (40.5)% for the three and six months ended June 30, 2022, respectively, as compared to 69.2% and 2.8% for the three and six months ended June 30, 2021, respectively. The year-to-date rate is different from the combined federal and state statutory rate of 22.1% 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.

DPL's income tax expense for the six months ended June 30, 2022 was calculated using the estimated annual effective income tax rate for 2022 of (43.8)% on ordinary income. Management estimates the annual effective tax rate based on its forecast of annual pre-tax income or loss.

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.

AES Ohio sponsors a defined benefit pension plan for the majority of its employees.

We generally fund pension plan benefits as accrued in accordance with the minimum funding requirements of ERISA and, in addition, make voluntary contributions from time to time. There were $7.5 million and $9.8 million in employer contributions during the six months ended June 30, 2022 and 2021, respectively.

The amounts presented in the following tables for pension include the collective bargaining plan formula, the traditional management plan formula, the cash balance plan formula and the SERP, in the aggregate. 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 plan. The components of net periodic benefit costs other than service costs are included in "Other income" in the Condensed Consolidated Statements of Operations.

The net periodic benefit cost of the pension benefit plans for the three and six months ended June 30, 2022 and 2021 was:

Contractual Obligations, Commercial Commitments and Contingencies

Commitments and Contingencies

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 June 30, 2022, AES Ohio could be responsible for the repayment of 4.9%, or $53.9 million, of $1,099.9 million OVEC debt obligations if they came due, comprised of both fixed and variable rate securities with maturities from 2022 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.

Contingencies

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 June 30, 2022, cannot be reasonably determined.

Environmental Matters

DPL’s and AES Ohio’s current and previously-owned facilities and operations are subject to a wide range of federal, state and local environmental regulations and laws. The environmental issues that may affect us include:

•The federal CAA and state laws and regulations (including State Implementation Plans) which require compliance, obtaining permits and reporting as to air emissions;

•Litigation with federal and certain state governments and certain special interest groups regarding whether modifications to or maintenance of certain coal-fired generating stations require additional permitting or pollution control technology, or whether emissions from coal-fired generating stations cause or contribute to global climate changes;

•Rules and future rules issued by the EPA, the Ohio EPA or other authorities that require or will require substantial reductions in SO2, particulates, mercury, acid gases, NOx and other air emissions;

•Rules and future rules issued by the EPA, the Ohio EPA or other authorities that require or will require reporting and reductions of GHGs;

•Rules and future rules issued by the EPA, the Ohio EPA or other authorities associated with the federal Clean Water Act, which prohibits the discharge of pollutants into waters of the United States except pursuant to appropriate permits; and

•Solid and hazardous waste laws and regulations, which govern the management and disposal of certain waste. Most of the solid waste created from the combustion of coal and fossil fuels is fly ash and other coal combustion by-products.

In addition to imposing continuing compliance obligations, federal, state and local environmental laws 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 our facilities to comply, or to determine compliance, with such regulations. We record liabilities for loss contingencies related to environmental matters when a loss is probable of occurring and can be reasonably estimated in accordance with the provisions of GAAP. Accordingly, we have immaterial accruals for loss contingencies for environmental matters. We also have several environmental matters for which we have not accrued loss contingencies because the risk of loss is not probable, or a loss cannot be reasonably estimated. We evaluate the potential liability related to environmental matters quarterly and may revise our estimates. Such revisions in the estimates of the potential liabilities could have a material adverse effect on our results of operations, financial condition and cash flows.

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

Business Segments

Business Segments

DPL manages its business through one reportable operating segment, the Utility segment. The primary segment performance measure is income / (loss) from continuing operations 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 discussed further below.

Utility Segment

The Utility segment is comprised of AES Ohio’s electric transmission and distribution businesses, which distribute electricity to residential, commercial, industrial and governmental customers. AES Ohio distributes electricity to approximately 535,000 retail customers located in a 6,000-square mile area of West Central 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 recording 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. The Utility segment includes revenues and costs associated with our investment in OVEC.

Included within the “Other” column are other businesses that do not meet the GAAP requirements for disclosure as reportable segments as well as certain corporate costs, which include interest expense on DPL's long-term debt as well as adjustments related to purchase accounting from the Merger. The accounting policies of the reportable segment are the same as those described in Note 1 – Overview and Summary of Significant Accounting Policies of our 10-K. Intersegment sales, costs of sales and expenses are eliminated in consolidation. Certain shared and corporate costs are allocated between "Other" and the Utility reporting segment.

Discontinued Operations

Discontinued Operations

Conesville - In May 2020, AEP, the operator of the formerly co-owned Conesville EGU, retired Conesville Unit 4 as planned. On June 5, 2020, DPL and AES Ohio Generation, together with AEP, completed the transfer of their interests in the retired Unit 4, including the associated environmental liabilities, to an unaffiliated third-party purchaser. For the transaction, DPL made quarterly cash expenditures, totaling $4.0 million, through June 2022. The transfer of Conesville Unit 4 was the last step in DPL's plan to exit its AES Ohio Generation business operations.

DPL determined that the transfer of Conesville and the previous transfers and sales of other AES Ohio Generation assets constitute the disposal of a group of components, which, as a whole, represent a strategic shift to exit its

AES Ohio Generation business. As such, the disposal of this group of components qualified to be presented as discontinued operations. Therefore, the results of operations of this group of components have been reported as such in the Condensed Consolidated Statements of Operations for the period indicated below.

The following table summarizes the revenues, operating costs, other expenses and income tax of discontinued operations for the period indicated:

Risks and Uncertainties

COVID-19 Pandemic

The COVID-19 pandemic has impacted global economic activity, including electricity and energy consumption, and caused significant volatility in financial markets. Social distancing measures designed to slow the spread of the virus, such as business closures and operations limitations, impact energy demand within our service territory. We continue to take a variety of measures in response to the spread of COVID-19 to ensure our ability to transmit, distribute and sell electric energy, ensure the health and safety of our employees, contractors, customers and communities and provide essential services to the communities in which we operate. The magnitude and duration of the COVID-19 pandemic is unknown at this time and may have material and adverse effects on our results of operations, financial condition and cash flows in future periods.

Description of Business

DPL is a regional energy company organized in 1985 under the laws of Ohio. DPL has one reportable segment, the Utility segment. See Note 9 – Business Segments for more information relating to this reportable segment. The terms “we,” “us,” “our” and “ours” are used to refer to DPL and its subsidiaries.

DPL is an indirectly wholly-owned subsidiary of AES. DP&L, a wholly-owned subsidiary of DPL that 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 535,000 customers located in West Central Ohio. Additionally, AES Ohio 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. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. 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 sells its proportional share of energy and capacity from its investment in OVEC into the wholesale market.

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. In prior periods, AES Ohio Generation was also a primary subsidiary and sold all of its energy and capacity into the wholesale market. AES Ohio Generation retired its only remaining operating asset in May 2020 and sold it in June 2020. See Note 11 – Discontinued Operations for more information. 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.

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.

Certain immaterial amounts from prior periods have been reclassified to conform to the current period presentation. All material intercompany accounts and transactions are eliminated in consolidation.

Interim Financial Presentation

The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASB ASC, 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, changes in common shareholder's deficit, and cash flows. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of expected results for the year ending December 31, 2022. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2021 audited consolidated financial statements and notes 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 revenues and expenses of the periods reported. Actual results could differ from these estimates and assumptions.

Significant items subject to such estimates and assumptions include: recognition of revenue including unbilled revenues; the carrying value of property, plant and equipment; 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; and assets and liabilities related to employee benefits.

Accounting for Taxes Collected from Customers and Remitted to Governmental Authorities

AES Ohio collects certain excise taxes levied by state or local governments from its customers. These taxes are accounted for on a net basis and not included in revenue. The amounts of such taxes collected for the three and six months ended June 30, 2022 and 2021 were as follows:

	Three months ended				Six months ended
	June 30,				June 30,

Long-term debt covenants and restrictions

The DPL Credit Agreement has two financial covenants. The first financial covenant, a minimum EBITDA, calculated at the end of each fiscal quarter for the four prior fiscal quarters of $125.0 million is required, stepping up to $130.0 million on September 30, 2022 and $150.0 million on December 31, 2022. As of June 30, 2022, DPL was in compliance with this financial covenant.

The second financial covenant is an EBITDA to Interest Expense ratio that is calculated, at the end of each fiscal quarter, by dividing EBITDA for the four prior fiscal quarters by the consolidated interest charges for the same period. The ratio, per the agreement, is to be not less than 1.70 to 1.00, and steps up to 1.75 to 1.00 on September

30, 2022 and 2.00 to 1.00 as of December 31, 2022. As of June 30, 2022, DPL was in compliance with this financial covenant.

The DPL Credit Agreement also restricts dividend payments from DPL to AES, such that DPL cannot make dividend payments unless at the time of, and/or as a result of the distribution, (i) DPL’s leverage ratio does not exceed 0.67 to 1.00 and DPL’s interest coverage ratio is not less than 2.50 to 1.00 or, if such ratios are not within the parameters, (ii) DPL’s senior long-term debt rating from two of the three major credit rating agencies is at least investment grade. As a result, as of June 30, 2022, DPL was prohibited from making a distribution to its shareholder or making a loan to any of its affiliates (other than its subsidiaries).

Starting with the quarter ended September 30, 2021, the borrowing limit on the DPL Credit Agreement will be reduced by $5.0 million per quarter should the Total Debt to EBITDA ratio for the period of four consecutive quarters exceed 7.00 to 1.00. As of June 30, 2022, DPL exceeded this ratio and the borrowing limit was reduced from $95.0 million to $90.0 million.

The AES Ohio Credit Agreement and Bond Purchase Agreement (financing document entered into in connection with the issuance of AES Ohio's First Mortgage Bonds, on July 31, 2020) has 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 June 30, 2022, AES Ohio was in compliance with this financial covenant.

As of June 30, 2022, DPL and AES Ohio were in compliance with all debt covenants, including the financial covenants described above.

Distribution Rate Case

On November 30, 2020, AES Ohio filed a new distribution rate case with the PUCO. This rate case proposes a revenue increase of $120.8 million per year and incorporates the DIR investments that were planned and approved in the last rate case but not yet included in distribution rates, other distribution investments since September 2015 and investments necessitated by the tornados that occurred on Memorial Day in 2019. The rate case also includes a proposal for increased tree-trimming expenses and certain customer demand-side management programs and recovery of prior-approved regulatory assets for tree trimming, uncollectible expenses and rate case expense. A hearing on this case was held in January 2022, and the case is pending a commission order. Certain parties that have intervened in the distribution rate case have argued that ESP 1 incorporates a distribution rate freeze. Oral arguments regarding the potential rate freeze were held in May 2022. We are unable to predict the outcome of the distribution rate case, but if the PUCO were to impose a rate freeze that precludes AES Ohio’s ability to implement a distribution rate increase during ESP 1, it could have a material adverse effect on our results of operations, financial condition and cash flows.

Long-term debt covenants and restrictions

The DPL Credit Agreement has two financial covenants. The first financial covenant, a minimum EBITDA, calculated at the end of each fiscal quarter for the four prior fiscal quarters of $125.0 million is required, stepping up to $130.0 million on September 30, 2022 and $150.0 million on December 31, 2022. As of June 30, 2022, DPL was in compliance with this financial covenant.

The second financial covenant is an EBITDA to Interest Expense ratio that is calculated, at the end of each fiscal quarter, by dividing EBITDA for the four prior fiscal quarters by the consolidated interest charges for the same period. The ratio, per the agreement, is to be not less than 1.70 to 1.00, and steps up to 1.75 to 1.00 on September

30, 2022 and 2.00 to 1.00 as of December 31, 2022. As of June 30, 2022, DPL was in compliance with this financial covenant.

The DPL Credit Agreement also restricts dividend payments from DPL to AES, such that DPL cannot make dividend payments unless at the time of, and/or as a result of the distribution, (i) DPL’s leverage ratio does not exceed 0.67 to 1.00 and DPL’s interest coverage ratio is not less than 2.50 to 1.00 or, if such ratios are not within the parameters, (ii) DPL’s senior long-term debt rating from two of the three major credit rating agencies is at least investment grade. As a result, as of June 30, 2022, DPL was prohibited from making a distribution to its shareholder or making a loan to any of its affiliates (other than its subsidiaries).

Starting with the quarter ended September 30, 2021, the borrowing limit on the DPL Credit Agreement will be reduced by $5.0 million per quarter should the Total Debt to EBITDA ratio for the period of four consecutive quarters exceed 7.00 to 1.00. As of June 30, 2022, DPL exceeded this ratio and the borrowing limit was reduced from $95.0 million to $90.0 million.

The AES Ohio Credit Agreement and Bond Purchase Agreement (financing document entered into in connection with the issuance of AES Ohio's First Mortgage Bonds, on July 31, 2020) has 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 June 30, 2022, AES Ohio was in compliance with this financial covenant.

As of June 30, 2022, DPL and AES Ohio were in compliance with all debt covenants, including the financial covenants 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.
