DPL Inc.
Notes to Unaudited Condensed Consolidated Financial Statements
For the six months ended June 30, 2021

Note 1 – Overview and Summary of Significant Accounting Policies

Description of Business
DPL is a regional energy company organized in 1985 under the laws of Ohio. DPL has 1 reportable segment: the Utility segment. See Note 10 – 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 532,000 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 and the market price of electricity. AES Ohio owned interests in the retired Hutchings Coal Station until its transfer in 2020, and currently 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. In 2020, AES Ohio Generation's only operating asset was an undivided interest in Conesville, which closed in May 2020 and was sold in June 2020. See Note 12 – 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. We have evaluated subsequent events through the date this report is issued.

These financial statements have been prepared in accordance with GAAP, as contained in the FASB ASC, for interim financial statements 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. Therefore, our interim financial statements in this report should be read along with the annual financial statements included in our Form 10-K for the fiscal year ended December 31, 2020.

Table of Contents
In the opinion of our management, the Condensed Consolidated Financial Statements presented in this report contain all adjustments necessary to fairly state our financial position as of March 31,June 30, 2021; our results of operations

Table of Contents
for the three and six months ended March 31,June 30, 2021 and 2020, our cash flows for the threesix months ended March 31,June 30, 2021 and 2020 and the changes in our equity for the three and six months ended March 31,June 30, 2021 and 2020. Unless otherwise noted, all adjustments are normal and recurring in nature. Due to various factors, interim results for the three and six months ended March 31,June 30, 2021 may not be indicative of our results that will be realized for the full year ending December 31, 2021.

The preparation of financial statements in conformity with GAAP requires us to make estimates and judgments 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. Significant items subject to such estimates and judgments 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.

2020$0.4 $2.6 $(0.9)$0.9 $3.0 

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, 2021. Amounts are written off when reasonable collections efforts have been exhausted. During 2021, the current period provision and allowance for credit losses have decreased due to lower past due customer receivable balances. See Note 13 – Risks and Uncertainties for additional discussion of the COVID-19 pandemic.

Note 32 – Regulatory Matters

ESPSmart Grid and SEET ProceedingsComprehensive Settlement
On October 23, 2020, AES Ohio entered into a Stipulation and Recommendation (settlement) with the staff of the PUCO and various customers, and organizations representing customers of AES Ohio and certain other parties with respect to, among other matters, AES Ohio's applications pending at the PUCO for (i) approval of AES Ohio's plan to modernize its distribution grid (the Smart Grid Plan), (ii) findings that AES Ohio passed the SEET for 2018 and 2019, and (iii) findings that AES Ohio's current ESP 1 satisfies the SEET and the more favorable in the aggregate (MFA) regulatory test. The settlement is subject to, and conditioned upon, approval by the PUCO. A hearing was held in January 2021 for consideration of this settlement; a commissionsettlement and on June 16, 2021, the PUCO issued their opinion and order isaccepting the stipulation as filed. Applications for rehearing of the PUCO's orders relating to the comprehensive settlement were filed on July 16, 2021 and remain pending. Consistent with AES’ earlier statement of intent and based on recent discussions with AES, with the PUCO’s issuance of their opinion and order, DPL and AES Ohio expect that AES will make cash contributions of $150.0 million in 2021 to enable Smart Grid investment.

Decoupling
On January 23, 2020 AES Ohio filed with the PUCO requesting approval to defer its decoupling costs consistent with the methodology approved in its Distribution Rate Case. If approved, deferral would be effective December 18, 2019 and going forward would reduce impacts of weather, energy efficiency programs and economic changes in customer demand. An evidentiary hearing was held on this matter on May 4, 2021.

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. This case is pending a commission order. On July 26, 2021, the PUCO staff filed its Staff Report of Investigation in the distribution rate case. AES Ohio is preparing its response to this report. A hearing before the PUCO in this case has been set to begin on October 4, 2021.

FERC Proceedings
On November 15, 2018 the FERC issued a Notice of Proposed Rulemaking (NOPR) to address amortization of excess accumulated deferred income taxes resulting from the TCJA and their impact on transmission rates. Such notice requires all public utility transmission providers with stated transmission rates under an Open Access Transmission Tariff (OATT) to determine the amount of excess deferred income taxes caused by the TCJA. On March 3, 2020, AES Ohio filed an application before the FERC to change its transmission rate from a stated rate to a formula rate, which was accepted by the FERC and made effective as of May 3, 2020, subject to further proceeding and potential refunds. An uncontested settlement was filed December 10, 2020, which would increase the rates that were in effect prior to the filing but are a reduction from the rate that became effective subject to refund on May 3, 2020. Among other things, the settlement establishes new depreciation rates for our transmission assets and an authorized return on equity (ROE) of 9.85%, which would rise to 9.99% if the FERC were to approve in a separate ongoing proceeding a return on equity “adder” to recognize our continued membership in PJM. The 9.85% ROE (base) and 9.99% ROE (base + incentive) levels are subject to a four-year moratorium on other proposed ROE changes. Proposals to raise or lower the ROE could be filed with an effective date after the moratorium expires on April 14, 2025. The required flowback of excess deferred taxes under the NOPR was also addressed and resolved as part of this formula transmission rate settlement. On April 15, 2021, the FERC approved the transmission rate settlement. On July 15, 2021, in the separate proceeding, the FERC denied approval of the return on equity “adder” and ordered AES Ohio to modify its rates within 30 days to eliminate the "adder". AES Ohio intends to request rehearing of the order; however, if the Commission ultimately denies AES Ohio’s request in a final order, AES Ohio will also be required to refund amounts collected pursuant to the “adder” effective October 3, 2020 with interest. This amount is not expected to be material to the financial statements.

These financial instruments are not subject to master netting agreements or collateral requirements and as such are presented in the Condensed Consolidated Balance SheetSheets at their gross fair value, except for Long-term debt, which is presented at amortized carrying 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 threesix months ended March 31,June 30, 2021 or 2020.

Master Trust 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 $0.2$0.3 million and $(1.1)$0.8 million during the during the three months ended March 31,June 30, 2021 and 2020, respectively, and $0.5 million and $(0.3) million during the six months ended June 30, 2021 and 2020, respectively. These amounts are included in "Other income / (expense)" in our Condensed Consolidated Statements of Operations.

Long-term debt
The fair value of debt is based on current public market prices for disclosure purposes only. 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.

Table of Contents
All of the inputs to the fair value of our derivative instruments are from quoted market prices.

Our long-term debt is fair valued for disclosure purposes only and most of the fair values are determined using quoted market prices in inactive markets. 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.

Note 54 – Derivative Instruments and Hedging Activities

For further information on our derivative and hedge accounting policies, See Note 1 – Overview and Summary of Significant Accounting Policies – Financial Derivatives and Note 6 - Derivative Instruments and Hedging Activities of Item 8 – Financial Statements and Supplementary Data in our Form 10-K.

Cash Flow Hedges
In August 2020, the 2 interest rate swaps to hedge the variable interest on the $140.0 million variable interest rate tax-exempt First Mortgage Bonds expired, as the associated debt reached maturity. The interest rate swaps had a combined notional amount of $140.0 million and settled monthly based on a one-month LIBOR. The AOCL associated with the swaps was amortized out of AOCL into interest expense over the life of the underlying debt.

We also had 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 or losses recognized in AOCL for the cash flow hedges for the three and six months ended March 31,June 30, 2021 and 2020:

Lines of credit
At March 31,June 30, 2021 and December 31, 2020, the DPL revolving credit facility had outstanding borrowings of $80.0 million and $80.0 million, respectively. At March 31,June 30, 2021 and December 31, 2020, the AES Ohio revolving credit facility had outstanding borrowings of $80.0$100.0 million and $20.0 million, respectively.

DPL’s Senior Unsecured BondsSignificant transactions
On June 19, 2020 DPL closed a $415.0 million issuance of senior unsecured notes. These notes carry an interest rate of 4.125% and mature on July 1, 2025. Proceeds from the issuance and cash on hand were used to redeem in-full the remaining balance of $380.0 million of DPL's 7.25% senior unsecured notes. These bonds were redeemed at par plus accrued interest and a make-whole premium of $30.8 million on July 20, 2020.

DPL agreed to register the 2025 DPL 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 Senior Unsecured Bonds with the SEC on March 15, 2021, and this registration statement was declared effective on March 31, 2021. The exchange offer was closed on May 5, 2021.

On June 1, 2020 DPL amended its secured revolving credit facility. As a result of the amendment, the borrowing limit was reduced from $125.0 million to $110.0 million, the Total Debt to EBITDA covenant was eliminated, the EBITDA to Interest Expense covenant was reduced from 2.25 to 1.00 to 1.70 to 1.00, increasing to 1.75 to 1.00 as of September 30, 2022 and 2.00 to 1.00 as of December 31, 2022, and a trailing-twelve months minimum EBITDA covenant of $125.0 million was added, increasing to $130.0 million as of September 30, 2022 and $150.0 million as of December 31, 2022. Starting with the quarter ended September 30, 2021, the borrowing limit will be reduced by $5.0 million per quarter should DPL’s Total Debt to EBITDA ratio calculated for the period of four consecutive quarters exceed 7.00 to 1.00.

Long-term debt covenants and restrictions
DPL’s revolving credit agreement has 2 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 March 31,June 30, 2021, 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 4 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

Table of Contents
30, 2022 and 2.00 to 1.00 as of December 31, 2022. As of March 31,June 30, 2021, DPL was in compliance with this financial covenant.

DPL’s secured revolving 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 March 31,June 30, 2021, DPL was prohibited from making a distribution to its shareholder or making a loan to any of its affiliates (other than its subsidiaries).

AES Ohio's unsecured revolving credit facility 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

As of March 31,June 30, 2021, 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.

Note 76 – Income Taxes

DPL's provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. The following table details the effective tax rates for the three and six months ended March 31,June 30, 2021 were 69.2% and 2020.
Three months ended
March 31,
20212020
DPL(3.8)%(11.8)%

DPL’s effective combined state2.8%, respectively, and federal income tax rate for all operations was (3.8)%50.0% and 37.2% for the three and six months ended March 31, 2021. ThisJune 30, 2020, respectively. The year-to-date rate is different from the combined federal and state statutory rate of 22.5% 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'sincome tax expense for the threesix months ended March 31,June 30, 2021 was calculated using the estimated annual effective income tax rates for 2021 of (3.8)%2.6%. 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 DPLand its subsidiaries. Under a tax sharing agreement with AES, DPLis responsible for the income taxes associated with its own taxable income and records the provision for income taxes using a separate return method.

Note 87 – 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 $9.8 million and $7.5 million in employer contributions during the threesix months ended March 31,June 30, 2021 and 2020, 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 / (expense) 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 $8.8$8.5 million at March 31,June 30, 2021 and $9.0 million at December 31, 2020 were not material to the financial statements in the periods covered by this report.

Note 8 – Shareholder's Deficit

Capital Contributions from AES
There were no capital contributions during the six months ended June 30, 2021.

During the six months ended June 30, 2020, DPL received $150.0 million in a cash contribution from AES, which DPL then used to make a $150.0 million capital contribution to AES Ohio. The contribution at DPL represented an equity capital contribution of $98.0 million and a payment of $52.0 million against its tax receivable. The proceeds from the capital contribution at AES Ohio will primarily be used for funding needs to support AES Ohio's capital expenditure program, mainly new investments in and upgrades to AES Ohio’s transmission and distribution system.

Note 9 – Contractual Obligations, Commercial Commitments and Contingencies

Guarantees
Previously, DPL entered into various agreements with its wholly-owned subsidiary, AES Ohio Generation, providing financial or performance assurance to third parties. These agreements were entered into primarily to support or enhance the creditworthiness otherwise attributed to the subsidiary on a stand-alone basis, thereby facilitating the extension of sufficient credit to accomplish this subsidiary's intended commercial purposes. With the completion of our plan to exit generation, AES Ohio Generation currently does not require such assurances to third parties, and existing guarantees will expire in June 2021. During the threesix months ended March 31,June 30, 2021, DPL did not incur any losses related to the guarantees of these obligations, and we believe it is unlikely that DPL would be required to perform or incur any losses in the future associated with any of the above guarantees. At March 31,June 30, 2021, DPL had $1.9 million of such guarantees on behalf of AES Ohio Generation. There were no outstanding balances for commercial transactions covered by these guarantees at March 31,June 30, 2021 or December 31, 2020.

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. At March 31,June 30, 2021, AES Ohio could be responsible for the repayment of 4.9%, or $62.0$58.6 million, of $1,264.5$1,196.3 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
23

Table of Contents
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 March 31,June 30, 2021, 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 USEPA, 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 USEPA, the Ohio EPA or other authorities that require or will require reporting and reductions of GHGs;
23

Table of Contents
Rules and future rules issued by the USEPA, 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. The majority of solid waste created from the combustion of coal and fossil fuels consists of fly ash and other coal combustion by-products.

In addition to 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 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.

Note 10 – Business Segments

DPL manages its business through 1 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 532,000 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
24

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 and the historical results of AES Ohio’s Hutchings Coal Station, which was closed in 2013 and transferred to a third party in the fourth quarter of 2020.

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.

Note 11 – Revenue

Revenue is primarily earned from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities. For further discussion of our Retail, Wholesale, RTO ancillary, and Capacity revenues, see Note 14 — Revenue in Item 8.—Financial Statements and Supplementary Data of our Form 10-K.

DPL's revenue from contracts with customers was $172.1$147.4 million and $167.0$148.3 million for the three months ended March 31,June 30, 2021 and 2020, respectively; and $319.5 million and $315.3 million for the six months ended June 30, 2021 and 2020, respectively.

Note 12 – 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 will make quarterly cash expenditures, totaling $4.0 million, through July 2022,
26

of which $2.2$2.6 million has been paid through March 31,June 30, 2021. 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 along with the transfers of Stuart and Killen in 2019 and the sales of the Peaker Assets in 2018 and Miami Fort and Zimmer in 2017 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 qualifies to be presented as discontinued operations. Therefore, the results of operations of this group of components werehave been reported as such in the Condensed Consolidated Statements of Operations for all periods presented.

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

Notes to Unaudited Condensed Financial Statements

Note 1 – Overview and Summary of Significant Accounting Policies

Description of Business
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 532,000 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 and the market price of electricity. AES Ohio owned interests in the retired Hutchings Coal Station until its transfer in 2020, and currently 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 1 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 and the historical results of AES Ohio’s Hutchings Coal Station. 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.

We have evaluated subsequent events through the date this report is issued.

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

These financial statements have been prepared in accordance with GAAP, as contained in the FASB ASC, for interim financial statements 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. Therefore, our interim financial statements in this report should be read along with the annual financial statements included in our Form 10-K for the fiscal year ended December 31, 2020.

In the opinion of our management, the Condensed Financial Statements presented in this report contain all adjustments necessary to fairly state our financial position as of March 31,June 30, 2021; our results of operations for the three and six months ended March 31,June 30, 2021 and 2020, our cash flows for the threesix months ended March 31,June 30, 2021 and 2020 and the changes in our equity for the three and six months ended March 31,June 30, 2021 and 2020. Unless otherwise noted, all adjustments are normal and recurring in nature. Due to various factors, interim results for the three and six months ended March 31,June 30, 2021 may not be indicative of our results that will be realized for the full year ending December 31, 2021.

The preparation of financial statements in conformity with GAAP requires us to make estimates and judgments 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. Significant items subject to such estimates and judgments 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.

2020$0.4 $2.6 $(0.9)$0.9 $3.0 

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, 2021. Amounts are written off when reasonable collections efforts have been exhausted. During 2021, the current period provision and allowance for credit losses have decreased due to lower past due customer receivable balances. See Note 11 – Risks and Uncertainties for additional discussion of the COVID-19 pandemic.

Inventories
Inventories consist of materials and supplies at March 31,June 30, 2021 and December 31, 2020.

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 March 31,June 30, 2021 and 2020 were $12.9 millionas follows:

Note 32 – Regulatory Matters

ESPSmart Grid and SEET ProceedingsComprehensive Settlement
On October 23, 2020, AES Ohio entered into a Stipulation and Recommendation (settlement) with the staff of the PUCO and various customers, and organizations representing customers of AES Ohio and certain other parties with respect to, among other matters, AES Ohio's applications pending at the PUCO for (i) approval of AES Ohio's plan to modernize its distribution grid (the Smart Grid Plan), (ii) findings that AES Ohio passed the SEET for 2018 and 2019, and (iii) findings that AES Ohio's current ESP 1 satisfies the SEET and the more favorable in the aggregate (MFA) regulatory test. The settlement is subject to, and conditioned upon, approval by the PUCO. A hearing was held in January 2021 for consideration of this settlement; a commissionsettlement and on June 16, 2021, the PUCO issued their opinion and order isaccepting the stipulation as filed. Applications for rehearing of the PUCO's orders relating to the comprehensive settlement were filed on July 16, 2021 and remain pending. Consistent with AES’ earlier statement of intent and based on recent discussions with AES, with the PUCO’s issuance of their opinion and order, DPL and AES Ohio expect that AES will make cash contributions of $150.0 million in 2021 to enable Smart Grid investment.

Decoupling
On January 23, 2020 AES Ohio filed with the PUCO requesting approval to defer its decoupling costs consistent with the methodology approved in its Distribution Rate Case. If approved, deferral would be effective December 18, 2019 and going forward would reduce impacts of weather, energy efficiency programs and economic changes in customer demand. An evidentiary hearing was held on this matter on May 4, 2021.

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
36

Table of Contents
recovery of prior-approved regulatory assets for tree trimming, uncollectible expenses and rate case expense. This case is pending a commission order. On July 26, 2021, the PUCO staff filed its Staff Report of Investigation in the distribution rate case. AES Ohio is preparing its response to this report. A hearing before the PUCO in this case has been set to begin on October 4, 2021.

FERC Proceedings
On November 15, 2018 the FERC issued a Notice of Proposed Rulemaking (NOPR) to address amortization of excess accumulated deferred income taxes resulting from the TCJA and their impact on transmission rates. Such notice requires all public utility transmission providers with stated transmission rates under an Open Access Transmission Tariff (OATT) to determine the amount of excess deferred income taxes caused by the TCJA. On March 3, 2020, AES Ohio filed an application before the FERC to change its transmission rate from a stated rate to a formula rate, which was accepted by the FERC and made effective as of May 3, 2020, subject to further proceeding and potential refunds. An uncontested settlement was filed December 10, 2020, which would increase the rates that were in effect prior to the filing but are a reduction from the rate that became effective subject to refund on May 3, 2020. Among other things, the settlement establishes new depreciation rates for our transmission assets and an authorized return on equity (ROE) of 9.85%, which would rise to 9.99% if the FERC were to approve in a separate ongoing proceeding a return on equity “adder” to recognize our continued membership in PJM. The 9.85% ROE (base) and 9.99% ROE (base + incentive) levels are subject to a four-year moratorium on other proposed ROE changes. Proposals to raise or lower the ROE could be filed with an effective date after the moratorium expires on April 14, 2025. The required flowback of excess deferred taxes under the NOPR was also addressed and resolved as part of this formula transmission rate settlement. On April 15, 2021, the FERC approved the transmission rate settlement. On July 15, 2021, in the separate proceeding, the FERC denied approval of the return on equity “adder” and ordered AES Ohio to modify its rates within 30 days to eliminate the "adder". AES Ohio intends to request rehearing of the order; however, if the Commission ultimately denies AES Ohio’s request in a final order, AES Ohio will also be required to refund amounts collected pursuant to the “adder” effective October 3, 2020 with interest. This amount is not expected to be material to the financial statements.

Note 43 – Fair Value

The fair value of current financial assets and liabilities, debt service reserves and other deposits approximate their reported carrying amounts. The estimated fair values of our assets and liabilities have been determined using available market information. By virtue of these amounts being 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 5—Fair Value in Item 8. — Financial Statements and Supplementary Data of our Form 10-K.

These financial instruments are not subject to master netting agreements or collateral requirements and as such are presented in the Condensed Balance SheetSheets at their gross fair value, except for Long-term debt, which is presented at amortized carrying 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 threesix months ended March 31,June 30, 2021 or 2020.

Master Trust 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

We recorded net unrealized gains / (losses) of $0.2$0.3 million and $(1.1)$0.8 million during the during the three months ended March 31,June 30, 2021 and 2020, respectively, and $0.5 million and $(0.3) million during the six months ended June 30, 2021 and 2020, respectively. These amounts are included in "Other expense, net" in our Condensed Statements of Operations.

Long-term debt
The fair value of debt is based on current public market prices for disclosure purposes only. 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 2040 to 2061.

Table of Contents
All of the inputs to the fair value of our derivative instruments are from quoted market prices.

Our long-term debt is fair valued for disclosure purposes only and most of the fair values are determined using quoted market prices in inactive markets. These fair value inputs are considered Level 2 in the fair value hierarchy.

Cash Flow Hedges
In August 2020, the two interest rate swaps to hedge the variable interest on the $140.0 million variable interest rate tax-exempt First Mortgage Bonds expired, as the associated debt reached maturity. The interest rate swaps had a combined notional amount of $140.0 million and settled monthly based on a one-month LIBOR. The AOCL associated with the swaps was amortized out of AOCL into interest expense over the life of the underlying debt.

Note 109 – Contractual Obligations, Commercial 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. At March 31,June 30, 2021, AES Ohio could be responsible for the repayment of 4.9%, or $62.0$58.6 million, of $1,264.5$1,196.3 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
40

Table of Contents
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 March 31,June 30, 2021, 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 USEPA, 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 USEPA, the Ohio EPA or other authorities that require or will require reporting and reductions of GHGs;
Rules and future rules issued by the USEPA, 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, 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 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.

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 months ended March 31,June 30, 2021, Depreciation and amortization increased $1.4$0.4 million compared to the same period in the prior year. The increase was primarily the result of higher depreciable property, plant and equipment balances in the current year.

During the six months ended June 30, 2021, Depreciation and amortization increased $1.8 million compared to the same period in the prior year. The increase was primarily the result of higher depreciable property, plant and equipment balances in the current year.

DPL – Interest Expense
During the three months ended March 31,June 30, 2021, Interest expense decreased $3.3$3.8 million compared to the same period in the prior year. The decrease was primarily the result of the refinancing of debt at DPL in 2020.

DPL – Other Income / (Expense)
During the three months ended March 31, 2021, Other income / (expense) increased $1.4 million compared to the same period in the prior year. The increase was primarily the result of unrealized losses on AES Ohio's Master Trust assets in the prior year due to decreased fair value of investments.

DPL – Income Tax BenefitExpense From Continuing Operations
Income tax benefitexpense was $0.3$0.9 million during the three months ended MarchJune 30, 2021 compared to a benefitexpense of $0.1$2.8 million during the three months ended March 31,June 30, 2020. The decrease was primarily due to lower income from continuing operations before income tax in the current year versus the prior year.

Income tax expense was $0.6 million during the six months ended June 30, 2021 compared to expense of $2.7 million during the six months ended June 30, 2020. The decrease was primarily due to a lower effective tax rate in the current year versus the prior year.

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 532,000 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 and the historical results of AES Ohio’s Hutchings Coal Station, which was closed in 2013 and transferred to a third party in the fourth quarter of 2020.

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 10 – Business Segments of Notes to DPL's Condensed Consolidated Financial Statements for additional information regarding DPL’s reportable 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 3 - Regulatory Matters of our Form 10-K and Note 32 – Regulatory Matters of Notes to AES Ohio's Condensed Financial Statements.

KEY TRENDS AND UNCERTAINTIES

During the remainder of 2021 and beyond, we expect our results will be primarily impacted by retail demand and weather. As discussed in Note 32 – Regulatory Matters of Notes to DPL's Condensed Consolidated Financial Statements and Note 32 – 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 DRO.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. 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.

COVID-19 Pandemic
The COVID-19 pandemic has impacted global economic activity, including electricity and energy consumption, and caused significant volatility and negative pressure in financial markets. Responses to the COVID-19 pandemic by the State of Ohio and its residents and businesses in particular, continue to evolve including with respect to business and school closures and limitations and other social distancing measures and the effectiveness and timing ofas vaccine availability and distribution efforts.usage continues and the state and businesses review and adjust the scope and requirements of social distancing measures.

Social distancing measures designed to slow the spread of the virus, such as business closures and operations limitations, impact energy demand within our service industry. In addition to the impacts to demand within our service territory, we also have incurred and expect tomay continue to incur expenses relating to COVID-19, and such expenses may include those that relate to events outside of our control. We experienced impacts from the pandemic in 2020 and into 2021 and expect to continue to experience impacts for the remainder of 2021, and any such impacts during that time or in other future periods could have material and adverse effects on our results of operations, financial condition and cash flows. The following discussion highlights our assessment of the impacts of the COVID-19 pandemic on our current financial and operating status, and our financial and operational outlook based on information known as of this filing. Also see "Item 1A. Risk Factors" to our Form 10-K.

Business Continuity - During the COVID-19 pandemic, we are taking a variety of measures to ensure our ability to generate, 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. We continue to respond to this global crisis through comprehensive measures to protect our employees and others while fulfilling our vital role in providing our customers with electric energy. While stay-at-home restrictions have been lifted in our service territory, most of our management and administrative personnel are able to work remotely, and we have not experienced significant issues affecting our operations or ability to maintain effective internal controls and produce reliable financial information.

Demand - As the economic impact of the COVID-19 pandemic started to materialize in Ohio in the second half of March 2020 and continued for the duration of 2020 and into 2021, the COVID-19 pandemic primarily impacted our retail sales demand. Retail sales demand including for the quarter ended March 31,decreased in 2020 mostly from commercial and industrial customers, but has started to recover in 2021 as shown by the changes in weather-normalized volumes of kWh sold by customer class as follows:

Customer classFor the three months ended March 31, 2021 compared to the same period in 2020

Total(2.3)%(1.3)%9.3%(7.1)%2.9%(4.0)%

As noted above, we also have incurred and may continue to incur expenses relating to COVID-19, however see Note 3, Regulatory Matters - COVID-19 to our Form 10-K for a discussion of regulatory measures which partially mitigate the impact of these expenses. While we have continued to experience COVID-19 impacts into 2021, we

expect that such impacts would lessen as the scope and requirements of social distancing measures continue to be adjusted and energy demand improves. The ultimate 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.

Liquidity - We anticipate continuing to have sufficient liquidity to make all required payments, including payments for salaries and wages owed to our employees, during the COVID-19 pandemic. We also continue to not foresee a significant impact to our access to capital or our liquidity position as a result of the COVID-19 pandemic. For further discussion of our financial condition, liquidity, and 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.

Credit Exposures - We continue to monitor and manage our credit exposures in a prudent manner. During the year ended December 31, 2020, we experienced credit-related impacts from utility customers due to the prohibition of electric utilities, including us, from discontinuing electric utility service to customers through September 1, 2020 and due to the economic impacts of the COVID-19 pandemic, which began to improve in 2021. See Note 21Supplemental Financial InformationOverview and Summary of Significant Accounting Policies of Notes to DPL's Condensed Consolidated Financial Statements and Note 21Supplemental Financial Information orOverview and Summary of Significant Accounting Policies of Notes to AES Ohio's Condensed Financial Statements for further discussion of our allowance for credit losses. If these credit-related impacts from the COVID-19 pandemic continue into 2021 or beyond, further deterioration in our credit exposures and customer collections may result. However, as discussed in Note 3 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements and Note 3 – Regulatory Matters of Notes to AES Ohio's Financial Statements in Item 8. - Financial Statements and Supplementary Data of our Form 10-K, AES Ohio’s uncollectible expense is deferred for future collection.

Supply Chain - Our supply chain management has remained robust during this challenging time and we continue to closely manage and monitor developments.

Capital Projects - During the COVID-19 pandemic, our construction projects are 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.

CARES Act - The Coronavirus Aid, Relief, and Economic Security ("CARES") Act was passed by the U.S. Congress and signed into law on March 27, 2020. While we currently expect a limited impact from this legislation on our business, we have deferred the payment of federal payroll taxes in accordance with the provisions of this act. At March 31,June 30, 2021, the total deferral was approximately $2.1 million.

See Note 13 – Risks and Uncertainties of Notes to DPL's Condensed Consolidated Financial Statements and Note 1211 – Risks and Uncertainties of Notes to AES Ohio's Condensed Financial Statements for more information and Part II, Item 1a - Risk Factors of this Form 10-Q for more information.

Regulatory Environment
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 2020 Form 10-K and Form 10-Q previously filed with the SEC during 2021 describesdescribe other regulatory matters which have not materially changed since that filing.those filings. See Part I, Item 1, Note 32 – Regulatory Matters of Notes to DPL's Condensed Consolidated Financial Statements and Part I, Item 1, Note 32 – 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. This rate case proposes a revenue increase of $120.8 million and is pending a commission order. On July 26, 2021, the PUCO staff filed its Staff Report of Investigation in the distribution rate case. AES Ohio is preparing its response to this report. A hearing before the PUCO in this case has been set to begin on October 4, 2021.

Stipulation and Recommendation - - On October 23, 2020, AES Ohio entered into a Stipulation and Recommendation (settlement) with the staff of the PUCO and various customers, and organizations representing customers of AES Ohio and certain other organizations, which is subjectparties with respect to, among other matters, AES Ohio's applications pending at the PUCO approval. This Stipulationfor (i) approval of AES Ohio's plan to modernize its distribution grid (the Smart Grid Plan), (ii) findings that AES Ohio passed the SEET for 2018 and Recommendation would provide resolution on several matters pending before2019, and (iii) findings that AES Ohio's current ESP 1 satisfies the PUCO.SEET and the more favorable in the aggregate (MFA) regulatory test. A hearing was held in January 2021 for consideration of this settlement; a commissionsettlement and on June 16, 2021, the PUCO issued their opinion and order isaccepting the stipulation as filed. Applications for rehearing of the PUCO's orders relating to the comprehensive settlement were filed on July 16, 2021 and remain pending. Consistent with AES’ earlier statement of intent and based on recent discussions with AES, with the PUCO’s issuance of their opinion and order, DPL and AES Ohio expect that AES will make cash contributions of $150.0 million in 2021 to enable Smart Grid investment. See additional information in Note 32 – Regulatory Matters of Notes to DPL's Condensed Consolidated Financial Statements and Note 32 – Regulatory Matters of Notes to AES Ohio's Condensed Financial Statements.Statements.

Ohio House Bill 6 – Legislation was passed, Ohio House Bill 128, that repeals Ohio House Bill 6 provisions related to a nuclear fund and decoupling, effective June 30, 2021. Other provisions from Ohio House Bill 6 currently remain in place, which include the following: beginning January 1, 2020, permitted Ohio utilities, such as AES Ohio, may defer, recover or credit the net proceeds from selling energy and capacity received as part of their interest in OVEC and their OVEC-related costs through a statewide non-bypassable recovery mechanism through 2030; eliminates the annual energy efficiency targets for Ohio utilities after 2020; and allows Ohio utilities to construct customer-sited

renewable generation for mercantile customers or groups of mercantile customers, the costs of which may only be recovered from those customers. If these provisions from Ohio House Bill 6 are repealed without a replacement with comparable provisions, it could have a material adverse effect on our results of operations, financial condition and cash flows.

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 intends 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. On November 30, 2020, theThe ICE Benchmark Association ("IBA") announcedhas determined that it had begun consultation on its intention towill cease publication of one week and two specificmonth LIBOR rates by December 31, 2021, while extendingand will cease publication of the timeline for the overnight, one-month, three-month, six-month, and 12-month USD LIBOR rates throughby June 30, 2023. On March 5, 2021, IBA published a feedback statement for the consultation, announcing its intention to cease the publication of these rates on the specified dates. We maintain financial instruments that use LIBOR as an interest rate benchmark. Although the full impact of the reform remains unknown, we have begun to engage with our counterparties to discuss specific action items to be undertaken in order to prepare for amendments when they become due.

Environmental Matters
In addition to 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 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 2020 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;

Table of Contents
NAAQS; and
potential Clean Air Act Section 111(d) regulations for greenhouse gases from existing electric generating units.
Clean Air Act - Cross State Air Pollution Rule
CSAPR, which became effective in January 2015, addresses the "good neighbor" provision of the CAA, which prohibits sources within each state from emitting any air pollutant in an amount which will contribute significantly to any other state’s nonattainment, or interference with maintenance of, any NAAQS. The CSAPR is implemented, in part, through a market-based program under which compliance may be achievable through the acquisition and use of emissions allowances created by the USEPA. In October 2016, the USEPA published a final rule to update the CSAPR to address the 2008 ozone NAAQS (“CSAPR Update Rule”). The CSAPR Update Rule found that NOx ozone season emissions in 22 states (including Ohio) affect the ability of downwind states to attain and maintain the 2008 ozone NAAQS, and accordingly, the USEPA issued federal implementation plans that both generally provide updated CSAPR NOx ozone season emission budgets for electric generating units within these states and that implement these budgets through modifications to the CSAPR NOx ozone season allowance trading program. In December 2018, the USEPA determined that the 2016 CSAPR Update Rule fully satisfied 20 states (including Ohio) good neighbor obligations with respect to the 2008 Ozone NAAQS (“CSAPR Close-Out Rule”), obviating the need
56

Table of Contents
for the USEPA to promulgate Federal Implementation Plans (FIPs) in these states. In October 2019, the D.C. Circuit vacated and remanded the CSAPR Close-Out Rule. On July 28, 2020, the D.C. Circuit ordered the USEPA to issue FIPs addressing seven states’ (including Ohio) outstanding 2008 NAAQS “good neighbor” obligations by March 15, 2021. On April 30, 2021, the USEPA published a final rule to address the 2020 D.C. Circuit decision. The USEPA is issuing new or amended federal implementation plans for 12 states, including Ohio, with revised CSAPR NOx ozone season emission budgets for electric generating units within these states via a new CSAPR NOx Ozone Season Group 3 Trading Program. Implementation is to begin during the 2021 ozone season (May through September 2021) with an effective date 60 days following publication in the Federal Register of the final rule.June 28. Subject sources in these states will be required to surrender an equivalent number of previously allocated 2021-2024 Group 2 allowances by deadlines in 2021. This requirement applies inclusive of assets and allowances that have since been sold and/or retired. While DPL no longer operates electric generating units subject to the revised CSAPR Update Rule, prior AES Ohio Generation sources will be required to surrender an equivalent number of previously allocated 2021-2024 Group 2 allowances. We have accrued $0.9 millionIn July 2021, we acquired the required allowances and on July 14, 2021, the USEPA recalled an equivalent number of previously allocated 2021-2024 Group 1 allowances for Stuart and Killen fulfilling the costrequirement for surrender of purchasing allowances required under this rule. This accrual is included in Discontinued Operations on our Condensed Consolidated Statements of Operations.the revised CSAPR Update Rule.

CAPITAL RESOURCES AND LIQUIDITY

DPL and AES Ohio had unrestricted cash and cash equivalents of $34.1$16.7 million and $16.8$4.8 million, respectively, at March 31,June 30, 2021. 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 $1,412.9 million and $582.3 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.

Our discussion of DPL’s financial condition, liquidity and capital requirements include the results of its principal subsidiary AES Ohio.

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 2021 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.

If the rating agencies were to reduce our debt or credit ratings, our borrowing costs may increase, our potential pool of investors and funding resources may be reduced, and we may be required to post additional collateral under selected contracts. These events could have an adverse effect on our results of operations, financial condition and cash flows. In addition, any such reduction in our debt or credit ratings may adversely affect the trading price of our outstanding debt securities.

MARKET RISK

We are subject to certain market risks including, but not limited to, changes in commodity prices for electricity and fluctuations in interest rates. Our Risk Management Committee (RMC), comprised of members of senior management, is responsible for establishing risk management policies and the monitoring and reporting of risk exposures. The RMC meets on a regular basis with the objective of identifying, assessing and quantifying material risk issues and developing strategies to manage these risks.

The disclosures presented in this section are based upon a number of assumptions; actual effects may differ. The safe harbor provided in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 shall apply to the disclosures contained in this section. For further information regarding market risk, see Item 1A.—Risk Factors and Item 7A - Quantitative and Qualitative Disclosures about Market Risk of our Form 10-K. Our businesses may incur substantial costs and liabilities and be exposed to price volatility as a result of risks associated with the electricity markets, which could have a material adverse effect on our results of operations,

financial condition and cash flows. In addition, we may not be adequately hedged against our exposure to changes in interest rates.

Interest Rate Risk
Because of our normal investing and borrowing activities, our financial results are exposed to fluctuations in interest rates which we manage through our regular financing activities. We maintain both cash on deposit and investments in cash equivalents that may be affected by adverse interest rate fluctuations. DPL has fixed-rate long-term debt.

Long-term debt maturities and repayments occurring in the next twelve months are discussed under "CAPITAL RESOURCES AND LIQUIDITY".

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 derivative instruments; 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; the valuation of AROs; assets and liabilities related to employee benefits and intangible assets. Refer to our Form 10-K for the year ended December 31, 2020 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 threesix months ended March 31,June 30, 2021.

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.
