Overview and Summary of Significant Accounting Policies | OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES DPL, an indirectly wholly-owned subsidiary of AES, is a holding company organized in 1985 under the laws of Ohio. DPL owns all of the outstanding common stock of DP&L, which does business as AES Ohio. Substantially all of DPL’s business consists of transmitting, distributing and selling of electric energy conducted through its principal subsidiary, AES Ohio. The terms “we,” “us,” “our” and “ours” are used to refer to DPL and its subsidiaries. AES Ohio is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave Ohio consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, retail transmission and distribution services are still regulated. AES Ohio has the exclusive right to provide such transmission and distribution services to approximately 540,000 customers located in West Central Ohio. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. AES Ohio also provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. AES Ohio sources all of the generation for its SSO customers through a competitive bid process. AES Ohio's sales reflect the general economic conditions, seasonal weather patterns of the area, the market price of electricity and customer energy efficiency initiatives. AES Ohio owns numerous transmission facilities. AES Ohio records revenue and expenses for its proportional share of energy and capacity from its investment in OVEC. DPL’s other primary subsidiaries are MVIC and Miami Valley Lighting. MVIC is our captive insurance company that provides insurance services to AES Ohio and our other subsidiaries, and Miami Valley Lighting provides street and outdoor lighting services to customers in the Dayton region. DPL's subsidiaries are all wholly-owned. DPL also has a wholly-owned business trust, DPL Capital Trust II, formed for the purpose of issuing trust capital securities to investors. AES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, AES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses and records regulatory assets when incurred costs are expected to be recovered in future customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs or overcollections of riders. 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. We have evaluated subsequent events through the date this report was issued. 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 FASC, for interim financial information and Article 10 of Regulation S-X issued by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income or loss, changes in shareholder's equity, and cash flows. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of expected results for the year ending December 31, 2024. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2023 audited consolidated financial statements and footnotes thereto, which are included in our Form 10-K. Use of Management Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the revenue and expenses of the periods reported. Actual results could differ from these estimates and assumptions. Significant items subject to such estimates and assumptions include: the carrying value of property, plant and equipment; unbilled revenue; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits. Reclassifications Certain amounts from prior periods have been reclassified to conform to the current period presentation. 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 March 31, 2024 December 31, 2023 Cash and cash equivalents $ 24.2 $ 41.0 Restricted cash (included in Prepayments and other current assets ) 0.1 0.1 Total cash, cash equivalents and restricted cash $ 24.3 $ 41.1 Accounts Receivable and Allowance for Credit Losses The following table summarizes accounts receivable as of March 31, 2024 and December 31, 2023: $ in millions March 31, 2024 December 31, 2023 Accounts receivable, net: Customer receivables $ 76.7 $ 71.0 Unbilled revenue 16.5 19.4 Amounts due from affiliates 1.6 0.8 Other 5.9 2.2 Allowance for credit losses (0.9) (0.9) Total accounts receivable, net $ 99.8 $ 92.5 The following table is a roll forward of our allowance for credit losses related to the accounts receivable balances for the three months ended March 31, 2024 and 2023: Three months ended March 31, $ in millions 2024 2023 Allowance for credit losses: Beginning balance $ 0.9 $ 0.5 Current period provision 0.8 0.9 Write-offs charged against allowance (1.0) (1.1) Recoveries collected 0.2 0.3 Ending balance $ 0.9 $ 0.6 Inventories Inventories consist of materials and supplies as of March 31, 2024 and December 31, 2023.

ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures The amendments in this section are designed to improve the disclosures related to segment reporting on an interim and annual basis. Public companies must disclose significant segment expenses and an amount for other segment items. This will also require that a company disclose its annual disclosures under Topic 280 in each interim period. Furthermore, companies will need to disclose the Chief Operating Decision Maker (“CODM”) and how the CODM assesses the performance of a segment. Lastly, public companies that have a single reportable segment must report the required disclosures under Topic 280. The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted.

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items] | |
Fair Value | FAIR VALUE The fair value of our financial assets and liabilities approximates their reported carrying amounts. The estimated fair values of our assets and liabilities have been determined using available market information. Because these amounts are estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. For further information on our valuation techniques and policies, see Note 3. Fair Value in Item 8. Financial Statements and Supplementary Data of our Form 10-K. Financial Assets AES Ohio established a Master Trust to hold assets that could be used for the benefit of employees participating in employee benefit plans. These assets are not used for general operating purposes. These assets are primarily comprised of open-ended mutual funds, which are valued using the net asset value per unit. These assets are recorded at fair value within Other non-current assets on the Condensed Consolidated Balance Sheets and are classified as equity investments. Net unrealized gains related to equity investments still held as of March 31, 2024 and 2023 are as follows: Three months ended March 31, $ in millions 2024 2023 Net unrealized gains (a) $ 0.3 $ 0.3 (a) These amounts are included in Other income, net in our Condensed Consolidated Statements of Operations. We did not have any transfers of the fair values of our financial instruments between Level 1, Level 2 or Level 3 of the fair value hierarchy during the three months ended March 31, 2024 or 2023. Recurring Fair Value Measurements The fair value of assets and liabilities as of March 31, 2024 and December 31, 2023 measured on a recurring basis and the respective category within the fair value hierarchy for DPL is as follows: Fair value as of March 31, 2024 Fair value as of December 31, 2023 $ in millions Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets Master Trust assets Money market funds $ 0.2 $ — $ — $ 0.2 $ 0.6 $ — $ — $ 0.6 Mutual funds 7.4 — — 7.4 7.2 — — 7.2 Total assets $ 7.6 $ — $ — $ 7.6 $ 7.8 $ — $ — $ 7.8 Financial Instruments not Measured at Fair Value in the Condensed Consolidated Balance Sheets The fair value of long-term debt is based on current public market prices for disclosure purposes only. These fair value inputs are considered Level 2 in the fair value hierarchy. As the Wright-Patterson Air Force Base note is not publicly traded, the fair value inputs are considered Level 3 in the fair value hierarchy as there are no observable inputs. Unrealized gains or losses are not recognized in the financial statements as long-term debt is presented at carrying value, net of unamortized premium or discount and unamortized deferred financing costs. The long-term debt amounts include the current portion payable in the next twelve months and have maturities that range from 2025 to 2061. The following table presents the carrying amount, fair value, and fair value hierarchy of our financial liabilities that are not measured at fair value in the Condensed Consolidated Balance Sheets as of the periods indicated, but for which fair value is disclosed: March 31, 2024 December 31, 2023 Carrying Amount Fair Value Carrying Amount Fair Value $ in millions Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Liabilities Long-term debt $ 1,838.2 $ — $ 1,689.4 $ 16.8 $ 1,706.2 $ 1,837.6 $ — $ 1,706.2 $ 16.8 $ 1,723.0 |

Income Taxes | INCOME TAXES DPL’s provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. The effective combined state and federal income tax rates were 38.1% for the three months ended March 31, 2024 compared to 47.8% for the three months ended March 31, 2023. The year-to-date rate is different from the combined federal and state statutory rate of 22.4% primarily due to the flowthrough of the net tax benefit related to the reversal of excess deferred taxes of AES Ohio as a percentage of pre-tax book income or loss. AES Ohio began amortizing a deferred municipal tax shortage in September 2023, which partially offsets the ongoing amortization of the Tax Cut and Jobs Act (TCJA) benefit. DPL's income tax expense for the three months ended March 31, 2024 was calculated using the estimated annual effective income tax rate for 2023 of 34.6% 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. |

Contractual Obligations, Commercial Commitments and Contingencies | COMMITMENTS AND CONTINGENCIES Contingencies Legal Matters In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under various laws and regulations. We believe the amounts provided in our Condensed Consolidated Financial Statements, as prescribed by GAAP, are adequate considering the probable and estimable contingencies. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various legal proceedings, claims, tax examinations and other matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in our Condensed Consolidated Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided as of March 31, 2024, cannot be reasonably determined. Environmental Matters We are subject to various federal, state, regional and local environmental protection and health and safety laws and regulations governing, among other things, the generation, storage, handling, use, disposal and transportation of regulated materials, including ash and CCR; the use and discharge of water used in generation boilers and for cooling purposes; the emission and discharge of hazardous and other materials, including GHGs, into the environment; climate change; species and habitat protections; and the health and safety of our employees. These laws and regulations often require a lengthy and complex process of obtaining and renewing permits and other governmental authorizations from federal, state and local agencies. Violation of these laws, regulations or permits can result in substantial fines, other sanctions, permit revocation and/or facility shutdowns. We cannot assure that we have been or will be at all times in full compliance with such laws, regulations and permits. Where no accrued liability has been recognized, it is reasonably possible that some matters could be decided unfavorably to us and could require us to pay damages or make expenditures in amounts that could be material but could not be estimated as of March 31, 2024. We have taken steps to limit our exposure to environmental claims that could be raised with respect to our previously-owned and operated coal-fired generation units, but we cannot predict whether any such claims will be raised and, if they are, the extent to which they may have a material adverse effect on our results of operations, financial condition and cash flows. Accruals for legal loss and environmental contingencies were not material as of March 31, 2024 and December 31, 2023. Equity Ownership Interest AES Ohio has a 4.9% equity ownership interest in OVEC, which is recorded using the cost method of accounting under GAAP. AES Ohio, along with several non-affiliated energy companies party to an OVEC arrangement, receive and pay for OVEC capacity and energy and are responsible for OVEC debt obligations and other fixed costs in proportion to their power participation ratios under the arrangement, which, for AES Ohio, is the same as its equity ownership interest. As of March 31, 2024, AES Ohio could be responsible for the repayment of 4.9%, or $51.7 million, of $1.1 billion OVEC debt obligations if they came due, comprised of fixed rate securities with maturities from 2026 to 2040. OVEC could also seek additional contributions from AES Ohio to avoid a default in the event that other OVEC members defaulted on their respective OVEC obligations. |

The primary segment performance measure is income / (loss) before income tax as management has concluded that this measure best reflects the underlying business performance of DPL and is the most relevant measure considered in DPL’s internal evaluation of the financial performance of its segment. The Utility segment is comprised of AES Ohio, a public electric transmission and distribution utility, with all other nonutility business activities aggregated separately. See Note 1.

Description of Business | DPL, an indirectly wholly-owned subsidiary of AES, is a holding company organized in 1985 under the laws of Ohio. DPL owns all of the outstanding common stock of DP&L, which does business as AES Ohio. Substantially all of DPL’s business consists of transmitting, distributing and selling of electric energy conducted through its principal subsidiary, AES Ohio. The terms “we,” “us,” “our” and “ours” are used to refer to DPL and its subsidiaries. AES Ohio is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave Ohio consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, retail transmission and distribution services are still regulated. AES Ohio has the exclusive right to provide such transmission and distribution services to approximately 540,000 customers located in West Central Ohio. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. AES Ohio also provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. AES Ohio sources all of the generation for its SSO customers through a competitive bid process. AES Ohio's sales reflect the general economic conditions, seasonal weather patterns of the area, the market price of electricity and customer energy efficiency initiatives. AES Ohio owns numerous transmission facilities. AES Ohio records revenue and expenses for its proportional share of energy and capacity from its investment in OVEC. DPL’s other primary subsidiaries are MVIC and Miami Valley Lighting. MVIC is our captive insurance company that provides insurance services to AES Ohio and our other subsidiaries, and Miami Valley Lighting provides street and outdoor lighting services to customers in the Dayton region. DPL's subsidiaries are all wholly-owned. DPL also has a wholly-owned business trust, DPL Capital Trust II, formed for the purpose of issuing trust capital securities to investors. AES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, AES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses and records regulatory assets when incurred costs are expected to be recovered in future customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs or overcollections of riders. |
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.

The results of operations for the three months ended March 31, 2024 are not necessarily indicative of expected results for the year ending December 31, 2024. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2023 audited consolidated financial statements and footnotes thereto, which are included in our Form 10-K. Use of Management Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the revenue and expenses of the periods reported. Actual results could differ from these estimates and assumptions. Significant items subject to such estimates and assumptions include: the carrying value of property, plant and equipment; unbilled revenue; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits. |
