**AES Ohio**

**Notes to Unaudited Condensed Financial Statements**

**For the three and six months ended June 30, 2025 and 2024**

**1. OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

DP&L, which does business as AES Ohio, is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave Ohio consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, retail transmission and distribution services are still regulated. AES Ohio has the exclusive right to provide such transmission and distribution services to approximately 543,000 customers located in West Central Ohio. Principal industries located in AES Ohio's service territory include automotive, food processing, paper, plastic, manufacturing and defense. AES Ohio also provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. AES Ohio sources all of the generation for its SSO customers through a competitive bid process. AES Ohio's sales reflect the general economic conditions, seasonal weather patterns of the area, the market price of electricity and customer energy efficiency initiatives. AES Ohio owns numerous transmission facilities. AES Ohio records revenue and expenses for its proportional share of energy and capacity from its investment in OVEC. AES Ohio has one reportable segment, the Utility segment. In addition to AES Ohio's electric transmission and distribution businesses, the Utility segment includes revenue and expenses associated with AES Ohio's investment in OVEC. AES Ohio is an indirect majority-owned subsidiary of DPL.

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

**Agreement to Sell Minority Interest in AES Ohio**

On April 4, 2025, DPL LLC (formerly known as DPL Inc.) ("DPL") consummated the transactions contemplated by (i) a Purchase and Sale Agreement with Astrid Holdings LP ("Investor"), a wholly-owned subsidiary of CDPQ, dated as of September 13, 2024, pursuant to which DPL agreed to sell to Investor 15% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Holdings, Inc. ("Ohio Holdings" and, such agreement, the "Ohio Holdings Purchase Agreement") for a purchase price of approximately $272 million, and (ii) a Purchase and Sale Agreement with Investor, pursuant to which DPL agreed to sell to Investor 17.65% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Investments, Inc. ("Ohio Investments" and, such agreement, the "Ohio Investments Purchase Agreement" and together with the Ohio Holdings Purchase Agreement, the "Purchase Agreements") for a purchase price of approximately $272 million Pursuant to the consummation of the transactions contemplated by the Ohio Holdings Purchase Agreement and the Ohio Investments Purchase Agreement together, the ("Closings"), CDPQ owns an aggregate indirect equity interest in AES Ohio of approximately 30%, with total proceeds to DPL of approximately $544 million. There is no change in management or operational control of DPL, Ohio Investments, Ohio Holdings or AES Ohio as a result of these transactions.

Pursuant to the Purchase Agreements, prior to the Ohio Holdings Closing, DPL contributed to Ohio Holdings 100% of the issued and outstanding shares of AES Ohio, such that Ohio Holdings owns 100% of AES Ohio. Immediately after the Ohio Holdings Closing and immediately prior to the Ohio Investments Closing, DPL contributed to Ohio Investments 85% of the issued and outstanding shares of Ohio Holdings, such that Ohio Investments owns a direct equity interest in Ohio Holdings of 85%. Following the Closings, DPL owns 82.35% of the issued and outstanding shares of Ohio Investments, Ohio Investments owns 85% of the issued and outstanding shares of Ohio Holdings, and Ohio Holdings owns 100% of the issued and outstanding shares of AES Ohio.

**Financial Statement Presentation**

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

**Interim Financial Presentation**

The accompanying unaudited condensed financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASB ASC, for interim financial information and Article 10 of Regulation S-X issued

------

<u>[**Table of Contents**](#i17d6eadbcd9a4c6199ab3421b96c3bea_7)</u>

by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income or loss, changes in shareholder's equity, and cash flows. The results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of expected results for the year ending December 31, 2025. The accompanying condensed financial statements are unaudited and should be read in conjunction with the 2024 audited financial statements and footnotes thereto, which are included in our Form 10-K.

**Use of Management Estimates**

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

**Reclassifications**

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

**Cash, Cash Equivalents and Restricted Cash**

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

---

| | | |
|:---|:---|:---|
| **$ in millions** | **June 30, 2025** | **December 31, 2024** |
| Cash and cash equivalents | $37.8 | $24.6 |
| Restricted cash (included in *Prepayments and other current assets*) | 0.1 | 0.1 |
| &nbsp;&nbsp;Total cash, cash equivalents and restricted cash | $37.9 | $24.7 |

---

**Accounts Receivable and Allowance for Credit Losses**

The following table summarizes accounts receivable as of June 30, 2025 and December 31, 2024:

---

| | | |
|:---|:---|:---|
| **$ in millions** | **June 30, 2025** | **December 31, 2024** |
| Accounts receivable, net: |  |  |
| &nbsp;&nbsp;Customer receivables | $100.4 | $79.0 |
| &nbsp;&nbsp;Unbilled revenue | 28.6 | 24.1 |
| &nbsp;&nbsp;Amounts due from affiliates | 3.8 | 3.6 |
| &nbsp;&nbsp;Other | 13.7 | 6.0 |
| &nbsp;&nbsp;Allowance for credit losses | (10.1) | (6.1) |
| &nbsp;&nbsp;&nbsp;&nbsp;Total accounts receivable, net | $136.4 | $106.6 |

---

The following table is a roll forward of our allowance for credit losses related to the accounts receivable balances for the six months ended June 30, 2025 and 2024:

---

| | | |
|:---|:---|:---|
| | **Six months ended** | **Six months ended** |
| | **June 30,** | **June 30,** |
|<br>**$ in millions** | **2025** | **2024** |
| Allowance for credit losses: |  |  |
| &nbsp;&nbsp;Beginning balance | $6.1 | $0.9 |
| &nbsp;&nbsp;Current period provision | 3.6 | 2.3 |
| &nbsp;&nbsp;Write-offs charged against allowance | (0.3) | (2.7) |
| &nbsp;&nbsp;Recoveries and account write-ons | 0.7 | 0.5 |
| &nbsp;&nbsp;&nbsp;&nbsp;Ending balance | $10.1 | $1.0 |

---

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, of our receivables balance. Amounts are

------

<u>[**Table of Contents**](#i17d6eadbcd9a4c6199ab3421b96c3bea_7)</u>

written off when reasonable collections efforts have been exhausted. The current period provision and allowance for credit losses has increased due to a temporary pause of customer disconnections and certain collection efforts and write-off processes after the implementation of our customer billing system upgrade in the third quarter of 2024. AES Ohio reinstituted the customer disconnections process and collection efforts and write-off processes in late June 2025.

**2. REGULATORY MATTERS**

**Ohio Legislation, AES Ohio ESPs and Smart Grid Plans**

*Ohio Energy Legislation*

On April 30, 2025, the Ohio legislature passed new energy legislation (Sub. HB 15) that was signed by the Governor and will be effective August 14, 2025. The legislation allows Ohio's electric utilities to file three-year forecasted base distribution rate cases, which would replace electric security plans (ESPs) and associated recovery riders. Among other provisions, the legislation eliminates as of its effective date, the LGR, which currently allows for recovery of net OVEC costs and revenues. Changes to the regulatory framework from this legislation, including the recovery of any remaining regulatory asset balance amounts or future net OVEC costs and revenues, could be material to our results of operations, financial condition and cash flows. As of June 30, 2025, AES Ohio established a reserve of $3.2 million for the LGR regulatory asset.

*AES Ohio ESP* 

Current Ohio law requires utilities to file either an ESP or MRO plan to establish SSO rates. AES Ohio is currently operating pursuant to ESP 4, described in the paragraph below. From November 1, 2017 through December 18, 2019, AES Ohio operated pursuant to an approved ESP plan, which was initially approved on October 20, 2017 (ESP 3). On December 18, 2019, the PUCO approved AES Ohio's Notice of Withdrawal of ESP 3 and reversion to its prior rate plan (ESP 1). Among other items, the PUCO Order approving the ESP 1 rate plan included reinstating the non-bypassable RSC Rider, which provided annual revenue of approximately $79.0 million. The OCC has appealed to the Ohio Supreme Court the PUCO's decision approving the reversion to ESP 1 as well as argued for a

------

<u>[**Table of Contents**](#i17d6eadbcd9a4c6199ab3421b96c3bea_7)</u>

refund of the RSC revenue dating back to August 2021. Oral arguments regarding this appeal were held on April 22, 2025, and a court decision is pending.

*Smart Grid Comprehensive Settlement* 

On October 23, 2020, AES Ohio entered into a Stipulation and Recommendation (the Settlement) with the staff of the PUCO, various customers and organizations representing customers of AES Ohio and certain other parties with respect to, among other matters, AES Ohio's applications for (i) approval of AES Ohio's plan to modernize its distribution grid (Smart Grid Phase 1), (ii) findings that DP&L passed the SEET for 2018 and 2019, and (iii) findings that AES Ohio's ESP 1 satisfies the SEET and the more favorable in the aggregate (MFA) regulatory test. On June 16, 2021, the PUCO issued their opinion and order accepting the stipulation as filed. The OCC appealed the final PUCO order with respect to the 2018 and 2019 SEET to the Ohio Supreme Court on December 6, 2021. Oral arguments regarding this appeal were held on April 2, 2025, and a court decision is pending.

*Smart Grid Phase 2 Plan*

**Distribution Rate Case**

*2024 Distribution Rate Case application* 

On November 29, 2024, AES Ohio filed a distribution rate case with the PUCO. The investments reflected in this distribution rate case include investments to enhance the safety, reliability, and resilience of the distribution system. Among other matters, the application requests:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An increase to its annual distribution revenue requirement of $235.2 million, which incorporates certain investments that are currently recovered through the Distribution Investment Rider;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A return on equity of 10.95% and a cost of long-term debt of 4.49% on a distribution rate base of $1.3 billion and based on a capital structure of 53.87% equity and 46.13% long-term debt; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A date certain of September 30, 2024 and a test period of June 1, 2024 – May 31, 2025

The rate case application also includes a proposal for increased tree-trimming expenses. On June 27, 2025, the PUCO Staff submitted their Report and Recommendations; the PUCO has set the evidentiary hearing to begin September 9, 2025 and public hearings to be held on August 7 and August 14, 2025.

**Tax Savings Credit Rider**

As a result of the TCJA and the resulting decrease of the federal corporate income tax rate, AES Ohio established a Tax Savings Credit Rider (TSCR) for the purpose of returning certain benefits of the TCJA to customers, which was approved by the PUCO in 2018 as part of a stipulation adopted by the PUCO in AES Ohio's 2015 Distribution Rate Case. In November 2024, AES Ohio filed an application to update the TSCR to address an inadvertent normalization violation identified by the Company. On July 9, 2025, the PUCO approved AES Ohio's application to update its TSCR to correct the inadvertent normalization violation through collection of $13.6 million from customers over twelve months, which will be effective in August 2025.

**3. FAIR VALUE**

The fair value of our financial assets and liabilities approximates their reported carrying amounts. The estimated fair values of our assets and liabilities have been determined using available market information. Because these

------

<u>[**Table of Contents**](#i17d6eadbcd9a4c6199ab3421b96c3bea_7)</u>

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

**Financial Assets**

AES Ohio established a Master Trust to hold assets that could be used for the benefit of employees participating in employee benefit plans. These assets are not used for general operating purposes. These assets are primarily comprised of open-ended mutual funds, which are valued using the net asset value per unit. These assets are recorded at fair value within *Other non-current assets* on the Condensed Balance Sheets and are classified as equity investments. Net unrealized gains related to equity investments still held as of June 30, 2025 and 2024 are as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three months ended** | **Three months ended** | **Six months ended** | **Six months ended** |
| | **June 30,** | **June 30,** | **June 30,** | **June 30,** |
|<br>**$ in millions** | **2025** | **2024** | **2025** | **2024** |
| Net unrealized gains <sup>(a)</sup> | $0.3 | $— | $0.2 | $0.3 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*(a)*&nbsp;&nbsp;&nbsp;&nbsp;These amounts are included in *Other income / (expense), net* in our Condensed Statements of Operations.

We did not have any transfers of the fair values of our financial instruments between Level 1, Level 2 or Level 3 of the fair value hierarchy during the six months ended June 30, 2025 or 2024.

**Recurring Fair Value Measurements**

The fair value of assets and liabilities as of June 30, 2025 and December 31, 2024 measured on a recurring basis and the respective category within the fair value hierarchy for AES Ohio is as follows:

---

| | | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|:---|
| | **Fair value as of June 30, 2025** | **Fair value as of June 30, 2025** | **Fair value as of June 30, 2025** | **Fair value as of June 30, 2025** | **Fair value as of December 31, 2024** | **Fair value as of December 31, 2024** | **Fair value as of December 31, 2024** | **Fair value as of December 31, 2024** |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total assets | $7.8 | $— | $— | $7.8 | $8.0 | $— | $— | $8.0 |

---

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

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

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

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

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

**Revolving Credit Agreement**

AES Ohio entered into a third amendment and restatement of its $350 million revolving Credit Agreement on March 25, 2025 with a syndicate of bank lenders. The AES Ohio Credit Agreement is an unsecured committed line of credit to be used: (i) to finance capital expenditures; (ii) to refinance certain existing indebtedness, (iii) to support working capital; and (iv) for general corporate purposes. This agreement matures on March 25, 2030, and bears interest at variable rates as described in the agreement. It includes an uncommitted $150.0 million accordion feature to provide AES Ohio with an option to request an increase in the size of the facility at any time prior to March 25, 2029, subject to approval by the lenders. The AES Ohio Credit Agreement also includes two one-year extension options, allowing AES Ohio to extend the maturity date subject to approval by the lenders. As of June 30, 2025 and December 31, 2024, the AES Ohio Credit Agreement had outstanding borrowings of $160.0 million and $140.0 million, respectively.

**Term Loan Agreement** 

In August 2024, AES Ohio entered into an unsecured $150.0 million 364-day term loan agreement, which was fully drawn at closing with the proceeds being used for general corporate purposes. The AES Ohio Term Loan Agreement was originally set to mature on August 13, 2025, but was amended on July 30, 2025, to mature on October 13, 2025, and bears interest at variable rates as described in the agreement. The AES Ohio Term Loan Agreement contains customary representations, warranties and covenants, including a leverage covenant consistent with the leverage covenant contained in AES Ohio's Credit Agreement. AES Ohio has classified this agreement as short-term indebtedness as it matures in October 2025. Management plans to repay the AES Ohio Term Loan Agreement through a combination of cash from operations, new debt, and equity capital contributions.

**Long-term debt covenants and restrictions**

The AES Ohio Credit Agreement, AES Ohio Term Loan Agreement, and Fifty-Third, Fifty-Fourth and Fifty-Fifth Supplemental Indentures to the First Mortgage, pursuant to which the 3.20% Bonds due 2040, the 5.19% Bonds due 2033, the 5.49% Bonds due 2028 and the 5.70% Bonds due 2033 were issued, respectively, each contain one financial covenant. The covenant measures Total Debt to Total Capitalization and is calculated, at the end of each fiscal quarter, by dividing total debt at the end of the quarter by total capitalization at the end of the quarter. AES Ohio's Total Debt to Total Capitalization ratio shall not be greater than 0.67 to 1.00. As of June 30, 2025, AES Ohio was in compliance with this financial covenant.

------

<u>[**Table of Contents**](#i17d6eadbcd9a4c6199ab3421b96c3bea_7)</u>

AES Ohio does not have any meaningful restrictions in its debt financing documents prohibiting dividends and return of capital payments to its parent. As of June 30, 2025, AES Ohio was in compliance with all debt covenants, including the financial covenant described above.

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

**5. INCOME TAXES**

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

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three months ended** | **Three months ended** | **Six months ended** | **Six months ended** |
| | **June 30,** | **June 30,** | **June 30,** | **June 30,** |
| | **2025** | **2024** | **2025** | **2024** |
| Effective combined state and federal income tax rates | 42.1% | 20.1% | 26.0% | 19.9% |

---

The year-to-date rate is different from the combined federal and state statutory rate of 22.4% primarily due to the amortization of a municipal tax shortage, partially offset by the flowthrough of a net tax benefit related to the reversal of excess deferred taxes.

AES Ohio's income tax expense for the six months ended June 30, 2025 was calculated using the estimated annual effective income tax rate for 2025 of 25.8% on ordinary income. Management estimates the annual effective tax rate based on its forecast of annual pre-tax income or loss. Starting in the third quarter of 2025, the annual effective tax rate is expected to increase due to the flowthrough tax expense associated with the PUCO Order on the Tax Savings Credit Rider issued on July 9, 2025.

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

**6. BENEFIT PLANS**

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

The following table presents the net periodic benefit cost of the Pension Plans for the three and six months ended June 30, 2025 and 2024:

|<br>**$ in millions** | **2025** | **2024** | **2025** | **2024** |
| Service cost | $0.5 | $0.6 | $1.1 | $1.2 |
| Interest cost | 3.7 | 3.7 | 7.3 | 7.4 |
| Expected return on plan assets | (4.0) | (3.7) | (7.9) | (7.4) |
| Amortization of unrecognized: |  |  |  |  |
| Prior service cost | 0.3 | 0.2 | 0.5 | 0.4 |
| Actuarial loss | 1.2 | 1.0 | 2.5 | 2.0 |
| &nbsp;&nbsp;Net periodic benefit cost | $1.7 | $1.8 | $3.5 | $3.6 |

---

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

There were $7.5 million in employer contributions during the six month periods ended June 30, 2025 and June 30, 2024, respectively.

------

<u>[**Table of Contents**](#i17d6eadbcd9a4c6199ab3421b96c3bea_7)</u>

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

**7. SHAREHOLDER'S EQUITY**

During the six months ended June 30, 2025, Ohio Holdings made equity contributions of $150.0 million to AES Ohio.

During the six months ended June 30, 2024, DPL made equity contributions of $130.0 million to AES Ohio.

The proceeds from these equity contributions are intended primarily for funding needs related to AES Ohio's capital expenditure program.

**8. COMMITMENTS AND CONTINGENCIES**

**Contingencies**

*Legal Matters*

In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under various laws and regulations. We believe the amounts provided in our Condensed Financial Statements, as prescribed by GAAP, are adequate considering the probable and estimable contingencies. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various legal proceedings, claims, tax examinations and other matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in our Condensed Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided as of June 30, 2025, 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; 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, suspension or revocation of permits and/or facility shutdowns. There can be no assurance 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 have unfavorable outcomes for us and could require us to pay damages or make expenditures in amounts that could be material but could not be estimated as of June 30, 2025.

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 June 30, 2025 and December 31, 2024.

**Equity Ownership Interest**

AES Ohio has a 4.9% equity ownership interest in OVEC, which is recorded using the cost method of accounting under GAAP. AES Ohio, along with several non-affiliated energy companies party to an OVEC arrangement, receive and pay for OVEC capacity and energy and are responsible for OVEC debt obligations and other fixed costs in proportion to their power participation ratios under the arrangement, which, for AES Ohio, is the same as its equity ownership interest. As of June 30, 2025, AES Ohio could be responsible for the repayment of 4.9%, or $44.0 million, of $898.0 million OVEC debt obligations if they came due, comprised of fixed rate securities with maturities from

------

<u>[**Table of Contents**](#i17d6eadbcd9a4c6199ab3421b96c3bea_7)</u>

2026 to 2040. OVEC could also seek additional contributions from AES Ohio to avoid a default in the event that other OVEC members defaulted on their respective OVEC obligations.

**9. BUSINESS SEGMENTS**

Operating segments are components of an enterprise that engage in business activities from which it may earn revenue and incur expenses, for which separate financial information is available, and is evaluated regularly by the chief operating decision maker in assessing performance and deciding how to allocate resources. All of AES Ohio's current business consists of the transmission, distribution and sale of electric energy, and therefore AES Ohio had only one reportable segment, led by our Chief Executive Officer and Chief Financial Officer, who, collectively, are the Chief Operating Decision Maker. The primary segment performance measures are income / (loss) before income tax and net income / (loss) as management has concluded that these measures best reflect the underlying business performance of AES Ohio and are the most relevant measures considered in AES Ohio's internal evaluation of the financial performance of its segment. See Note 1, "*Overview and Summary of Significant Accounting Policies*" for further information on AES Ohio.

The following tables present financial information for AES Ohio's reportable business segment:

**10. REVENUE**

Revenue is primarily earned from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities. For further discussion of our Retail, Wholesale, RTO ancillary, and Capacity revenue, see Note 12. *Revenue* in Item 8. *Financial Statements and Supplementary Data* of our Form 10-K.

**<u>Revenue</u>**

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

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*(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.

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

**<u>Operation and Maintenance</u>**

During the three and six months ended June 30, 2025, Operation and Maintenance expense increased $4.0 million and $7.2 million, respectively, compared to the same periods in the prior year. The main drivers of these changes are as follows:

---

| | | |
|:---|:---|:---|
|<br>**$ in millions** | **Three months ended**<br>**June 30,**<br>**2025 vs. 2024** | **Six months ended**<br>**June 30,**<br>**2025 vs. 2024** |
| Increase in IT costs, primarily associated with customer billing system upgrade  | $2.4 | $6.3 |
| Other | 1.6 | 0.9 |
| &nbsp;&nbsp;Net change in operation and maintenance expense | $4.0 | $7.2 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*(a)*&nbsp;&nbsp;&nbsp;&nbsp;There is a corresponding offset in Revenue associated with these costs and minimal operating margin impact.

**<u>Depreciation and Amortization</u>**

During the three and six months ended June 30, 2025, Depreciation and amortization increased $8.3 million and $15.0 million, respectively, compared to the same periods in the prior year, primarily due to additional assets placed in service.

**<u>Taxes Other Than Income Taxes</u>**

During the three and six months ended June 30, 2025, Taxes other than income taxes increased $0.8 million and $7.8 million, respectively, compared to the same periods in the prior year. The increase was primarily the result of higher property taxes due to higher assessed values driven by AES Ohio's capital expenditure plan, net of regulatory deferrals.

**<u>Interest Expense, Net</u>**

During the three and six months ended June 30, 2025, Interest expense, net increased $2.0 million and $5.5 million, respectively, compared to the same periods in the prior year. The increases were primarily due to higher outstanding debt balances versus the comparable periods in the prior year.

**<u>Other Income / (Expense), Net</u>**

During the three and six months ended June 30, 2025, Other income / (expense), net decreased $1.7 million and $4.2 million, respectively, compared to the same periods in the prior year, primarily due to lower AFUDC equity.

**<u>Income Tax Expense</u>**

---

The increases / (decreases) in income tax expense of $0.2 million and $(0.4) million during the three and six months ended June 30, 2025, respectively, compared to the same periods of the prior year were primarily driven by higher pre-tax income in the prior year, offset by a decrease in the net tax benefit related to the reversal of excess deferred taxes and AFUDC equity.

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

**KEY TRENDS AND UNCERTAINTIES**

During 2025 and beyond, we expect our financial results will be primarily impacted by retail demand and weather. In addition, AES Ohio's financial results are likely to be driven by other factors including, but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulatory outcomes;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the timely recovery of transmission and distribution expenditures.

If favorable outcomes related to these factors do not occur, or if the challenges described below and elsewhere in this Quarterly Report impact us more significantly than we currently anticipate, then these factors, or other factors

------

unknown to us, may impact our operating income, net income and cash flows. We continue to monitor our operations and address challenges as they arise. For a discussion of the risks related to our business, see Item 1. *Business* and Item 1A. *Risk Factors* in our Form 10-K.

**Operational**

*Customer Information and Billing System Implementation* 

During the third quarter of 2024, we implemented our new customer information and billing system, SAP IS-U, a software solution that SAP developed for businesses operating in the utility industries. In connection with this implementation, a temporary pause of customer disconnections and certain collection efforts and write-off processes was instituted, which has resulted in a higher allowance for credit losses as of June 30, 2025. AES Ohio reinstituted the customer disconnections process and collection efforts and write-off processes in late June 2025.

*Capital Projects*

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

**Macroeconomic and Political**

*U.S. Utilities Load Growth and Large Load Customers*

The expansion of data center needs related to the growing use of generative artificial intelligence has the potential to be a significant accelerant to the load growth of the U.S. utilities market. AES Ohio is working with several companies to provide solutions for the electric service needs of data centers and we see these relationships growing as utilization of generative artificial intelligence drives the expansion of data center use within our service territory. As part of this process, AES Ohio is evaluating cost effective options to reliably serve these large data center customers.

*Trump Administration Actions*

On January 25, 2025, President Trump issued an Executive Order titled "*Declaring a National Energy Emergency*" directing agencies to, among other tasks, identify and exercise any lawful emergency authorities available to them to facilitate the identification, leasing, siting, production, transportation, refining, and generation of domestic energy resources.

*Tax*

The macroeconomic and political environments in the U.S. have changed in recent years. This could result in significant impacts to future tax law. In the U.S., the IRA included a 15% corporate alternative minimum tax (CAMT) based on adjusted financial statement income. In June 2025, the IRS released interim guidance for CAMT and announced its intention to revise regulations that were proposed in September 2024. The impact to the Company in 2025 is not expected to be material. We will continue to monitor the issuance of CAMT revised guidance.

On July 4, 2025, the United States enacted [H.R. 1] (the "2025 Act"). The legislation included amendments to, and extensions of, various U.S. corporate income tax provisions, which may impact our effective tax rate in future periods. However, the impact to the effective tax rate is not expected to be material. Our interpretation of the 2025 Act may change as the U.S. Treasury and the IRS issue additional guidance.

*Inflation* 

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

------

*Interest Rates* 

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

**Regulatory**

AES Ohio's facilities and operations are subject to a wide range of regulations and laws by federal, state and local authorities. As well as imposing continuing compliance obligations, these laws and regulations authorize the imposition of substantial penalties for noncompliance, including fines, injunctive relief and other sanctions. In the normal course of business, we have investigatory and remedial activities underway at these facilities and operations in an effort to comply, or to determine compliance, with such regulations. We record liabilities for losses that are probable and can be reasonably estimated. In addition to matters discussed or updated herein, our Form 10-K and Form 10-Q previously filed with the SEC during 2025 describe other regulatory matters, which have not materially changed since those filings.

*Ohio Energy Legislation*

On April 30, 2025, the Ohio legislature passed new energy legislation (Sub. HB 15) that was signed by the Governor and will be effective August 14, 2025. The legislation allows Ohio's electric utilities to file three-year forecasted base distribution rate cases, which would replace electric security plans (ESPs) and associated recovery riders. Among other provisions, the legislation eliminates as of its effective date, the LGR, which currently allows for recovery of net OVEC costs and revenues. Changes to the regulatory framework from this legislation, including the recovery of any remaining regulatory asset balance amounts or future net OVEC costs and revenues, could be material to our results of operations, financial condition and cash flows. As of June 30, 2025, AES Ohio established a reserve of $3.2 million for the LGR regulatory asset.

------

*AES Ohio ESP* and *Smart Grid Comprehensive Settlement* 

The OCC has appealed to the Ohio Supreme Court the PUCO's decision approving the reversion to ESP 1 as well as argued for a refund of the RSC revenue dating back to August 2021. Additionally, the OCC has appealed to the Ohio Supreme Court the PUCO's decision approving the Smart Grid Comprehensive Settlement as it relates to the 2018 and 2019 SEET. Oral arguments regarding these appeals were held in April 2025, and a court decision is pending.

*Smart Grid Phase 2 Plan*

*2024 Distribution Rate Case application* 

On November 29, 2024, AES Ohio filed a distribution rate case with the PUCO. The investments reflected in this distribution rate case include investments to enhance the safety, reliability, and resilience of the distribution system. Among other matters, the application requests:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An increase to its annual distribution revenue requirement of $235.2 million, which incorporates certain investments that are currently recovered through the Distribution Investment Rider;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A return on equity of 10.95% and a cost of long-term debt of 4.49% on a distribution rate base of $1.3 billion and based on a capital structure of 53.87% equity and 46.13% long-term debt; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A date certain of September 30, 2024 and a test period of June 1, 2024 – May 31, 2025

The rate case application also includes a proposal for increased tree-trimming expenses. On June 27, 2025, the PUCO Staff submitted their Report and Recommendations; the PUCO has set the evidentiary hearing to begin September 9, 2025 and public hearings to be held on August 7 and August 14, 2025.

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

**Environmental**

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

As a result of AES Ohio no longer directly owning or operating any generating stations, the following environmental matters, regulations and requirements are not expected to have a material impact on AES Ohio:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• MATS and any associated regulatory or judicial processes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• NAAQS; and

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

*Trump Administration Actions Affecting Environmental Regulations*

On January 20, 2025, President Trump issued an Executive Order titled "Unleashing American Energy" directing Agencies to, among other tasks, review regulations issued under the prior administration to determine whether they should be suspended, revised, or rescinded. The Trump Administration also issued a memorandum titled

------

"Regulatory Freeze Pending Review" directing agencies to refrain from proposing or issuing any rules until the Trump Administration has reviewed and approved those rules. In accordance with these and other Trump Administration Executive Orders, on March 12, 2025, EPA released a list of environmental regulations that will be targeted for reconsideration and other deregulatory action. These and other actions, including other Executive Orders and directives from the Trump Administration, may have an impact on regulations that may affect our business, financial condition, or results of operations.

*Clean Water Act - Regulation of Water Discharge*

The concept of "Waters of the U.S." ("WOTUS") defines the geographic reach and authority of the U.S. Army Corps of Engineers and the EPA (the "Agencies") to regulate streams, wetlands, and other water bodies under the CWA. There have been multiple Supreme Court decisions and dueling regulatory definitions over the past several years concerning the proper standard for how to properly determine whether a wetland or stream that is not navigable is considered a WOTUS. On May 25, 2023, the U.S. Supreme Court rendered a decision (the "Decision") in the case of Sackett v. Environmental Protection Agency, addressing the definition of WOTUS with regards to the CWA. The Decision provides a clear standard that substantially restricts the Agencies' ability to regulate certain types of wetlands and streams. Specifically, wetlands that do not have a continuous surface connection with traditional interstate navigable waters is not federally jurisdictional.

On September 8, 2023, the Agencies published final rule amendments in the Federal Register to amend the final "Revised Definition of 'Waters of the United States'" rule. This final rule conforms the definition of WOTUS to the definition adopted in the Decision. The Agencies have amended key aspects of the regulatory text to conform the rule to the Decision. On March 12, 2025, the Agencies issued a joint guidance memorandum for implementing the "continuous surface connection" consistent with the Decision and related issues. The Federal Register notice was published on March 24, 2025 outlining a process to gather recommendations for implementation of WOTUS. It is too early to determine whether any outcome of litigation or current or future revisions to rules interpreting federal jurisdiction over waters over the U.S. may have a material adverse effect on our results of operations, financial condition and cash flows.

*Regulation of CCR*

On October 19, 2015, an EPA rule regulating CCR under the Resource Conservation and Recovery Act as nonhazardous solid waste became effective ("CCR Rule"). The rule established nationally applicable minimum criteria for the disposal of CCR in new and currently operating landfills and surface impoundments, including location restrictions, design and operating criteria, groundwater monitoring, corrective action and closure requirements and post-closure care. The 2016 Water Infrastructure Improvements for the Nation Act ("WIIN Act"), includes provisions to implement the CCR Rule through a state permitting program, or if the state chooses not to participate, a possible federal permit program. The EPA has indicated that they will implement a phased approach to amending the CCR Rule, which is ongoing. On February 20, 2020, the EPA published a proposed rule to establish a federal CCR permit program that would operate in states without approved CCR permit programs. With the sale of our coal-fired generating stations, we expect that the impact of these regulations would be limited to our interest in OVEC.

On August 28, 2020, the EPA published the CCR Part A Rule that, among other amendments, required certain CCR units to cease waste receipt and initiate closure by April 11, 2021. The CCR Part A Rule also allowed for extensions of the April 11, 2021 deadline if EPA determines certain criteria are met. Facilities seeking such an extension were required to submit a demonstration to EPA by November 30, 2020. On January 11, 2022, EPA released its first in a series of proposed determinations regarding nine CCR Part A Rule demonstrations, including for OVEC's Clifty Creek and four compliance-related letters notifying certain other facilities of their compliance obligations under the federal CCR regulations. The determinations and letters include interpretations regarding implementation of the CCR Rule. On April 8, 2022, petitions for review were filed challenging these EPA actions. The petitions were consolidated in Electric Energy, Inc. v. EPA. On June 28, 2024, the court dismissed the petitions for review, finding that the EPA actions were an application of the existing CCR regulations. It is too early to determine the direct or indirect impact of this ruling or if additional litigation might be pursued.

On May 8, 2024, the EPA published final revisions to the CCR Rule, which were effective on November 8, 2024. The final revisions expand the scope of CCR units regulated by the CCR Rule to include legacy surface impoundments, inactive surface impoundments, and CCR management units. The May 8, 2024 revisions to the CCR Rule are currently subject to legal challenges and on November 1, 2024, the D.C. Circuit Court denied a

------

motion to stay these revisions to the CCR Rule. On November 5, 2024, an application for stay of the CCR Rule revisions was filed with the U. S. Supreme Court, which was denied by the court on December 11, 2024. On July 22, 2025, EPA published both a direct final rule and a proposed rule that, if finalized, would extend certain deadlines for coal combustion residual management units associated with its May 8, 2024 revisions to the CCR Rule. It is too early to determine any potential impact from these revisions to the CCR Rule.

**CAPITAL RESOURCES AND LIQUIDITY**

**OVERVIEW**

AES Ohio had unrestricted cash and cash equivalents of $37.8 million as of June 30, 2025. At that date, AES Ohio did not have any short-term investments. AES Ohio had aggregate principal amounts of long-term debt outstanding of $1,021.5 million.

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. AES Ohio must first seek approval from the PUCO to issue new stocks, bonds, notes and other evidences of indebtedness. AES Ohio last received approval in July 2025 to, among other things, issue up to $450 million of long-term indebtedness.

**CASH FLOWS**

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

**<u>Cash Flow Analysis</u>**

The following table summarizes the cash flows:

| &nbsp;&nbsp;**Net cash provided by operating activities** | $7.3 | $81.7 | $(74.4) |

---

&nbsp;&nbsp;&nbsp;&nbsp;

------

The net change in operating assets and liabilities during the six months ended June 30, 2025, compared to the six months ended June 30, 2024, was driven by the following:

---

| | |
|:---|:---|
| **$ in millions** | **$ Change** |
| Decrease from accounts payable primarily due to the timing of invoices and payments | $(39.9) |
| Decrease from higher net accounts receivable driven by timing of collections, billing delays and a temporary pause of customer disconnections and certain collection efforts and write-off processes after the implementation of AES Ohio's customer billing system upgrade in the third quarter of 2024 | (29.2) |
| Decrease from changes in interest accruals on outstanding debt in the comparable periods | (5.9) |
| Other | (5.7) |
| &nbsp;&nbsp;**Net change in operating assets and liabilities and other** | $(80.7) |

---

*<u>Investing activities</u>*

Net cash used in investing activities decreased $140.6 million during the six months ended June 30, 2025, compared to the six months ended June 30, 2024, primarily driven by the following:

---

| | |
|:---|:---|
| **$ in millions** | **$ Change** |
| Lower capital expenditures on AES Ohio T&D projects primarily due to timing of invoices and payments in the comparative periods and lower digital related investment due to the implementation of AES Ohio's customer billing system upgrade in the third quarter of 2024 | $130.6 |
| Lower cost of removal payments | 9.8 |
| Other | 0.2 |
| &nbsp;&nbsp;**Net change in investing activities** | $140.6 |

---

*<u>Financing activities</u>*

Net cash provided by financing activities decreased $59.7 million during the six months ended June 30, 2025, compared to the six months ended June 30, 2024, primarily driven by the following:

---

| | |
|:---|:---|
| **$ in millions** | **$ Change** |
| Decrease due to higher net repayments on AES Ohio's revolving credit facility | $(100.0) |
| Increase due to lower distributions to parent in the comparable periods | 21.0 |
| Increase due to higher equity contributions from parent in the comparable periods | 20.0 |
| Other | (0.7) |
| &nbsp;&nbsp;**Net change in financing activities** | $(59.7) |

---

**LIQUIDITY**

We expect our existing cash balances, cash generated from operating activities and borrowing capacity on our existing credit facilities will be adequate to meet our anticipated operating needs, including interest expense on our debt and any dividends to our equity owners. Our business is capital intensive, requiring significant resources to fund operating expenses, construction expenditures, scheduled debt maturities and carrying costs, taxes and any dividend payments. For 2025 and subsequent years, we expect to satisfy these requirements with a combination of cash from operations, funds from debt financing and funds from capital contributions as our internal liquidity needs and market conditions warrant. We also expect that the borrowing capacity under the AES Ohio Credit Agreement will continue to be available to manage working capital requirements during those periods. The absence of adequate liquidity could adversely affect our ability to operate our business and have a material adverse effect on our results of operations, financial condition and cash flows.

At June 30, 2025, AES Ohio has access to the following revolving credit facility:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **$ in millions** | **Type** | **Maturity** | **Commitment** | **Amounts available as of June 30, 2025** |
| AES Ohio Credit Agreement | Revolving | March 2030 | $350.0 | $190.0 |

---

For the AES Ohio Credit Agreement, as of June 30, 2025, there were $160.0 million in borrowings under the facility, with the remaining $190.0 million available to AES Ohio. For more information on the AES Ohio Credit Agreement, see Note 5. *Debt* of our Form 10-K.

| &nbsp;&nbsp;Total for DPL | $435.0 | $453.0 | $422.0 | $1310.0 |

---

AES Ohio's projection includes expected spending under its Smart Grid Phase 1 included in the comprehensive settlement approved by the PUCO on June 16, 2021, as well as new transmission and distribution projects. With the recent enactment of Sub. HB 15, AES Ohio withdrew its Smart Grid Phase 2 Application and is currently reevaluating its capital expenditure programs. AES Ohio's spending programs are contingent on, among other events, successful regulatory outcomes in pending proceedings. See more information in Note 2. *Regulatory Matters* of AES Ohio's Condensed Financial Statements.

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

**<u>Debt Covenants</u>**

For information regarding our long-term debt covenants, see Note 5. *Debt* of our Form 10-K.

**<u>Credit Ratings</u>**

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

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*(a)* Rating relates to AES Ohio's senior secured debt.

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

**<u>Off-Balance Sheet Arrangements</u>**

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

------

**CRITICAL ACCOUNTING POLICIES AND ESTIMATES**

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

Different estimates could have a material effect on our financial results. Judgments and uncertainties affecting the application of these policies and estimates may result in materially different amounts being reported under different conditions or circumstances. Historically, however, recorded estimates have not differed materially from actual results. Significant items subject to such judgments include: the carrying value of property, plant and equipment; unbilled revenue; the valuation of insurance and claims liabilities; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; liabilities recorded for income tax exposures; litigation; contingencies; assets and liabilities related to employee benefits and intangible assets. Refer to our Form 10-K for the year ended December 31, 2024 for a complete listing of our critical accounting policies and estimates. We have reviewed and determined that these remain as critical accounting policies as of and for the six months ended June 30, 2025.

***ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK***

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

***ITEM 4. CONTROLS AND PROCEDURES***

**Disclosure Controls and Procedures**

AES Ohio, under the supervision and with the participation of its management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), evaluated the effectiveness of our "disclosure controls and procedures," as such term is defined in Rule 13a-15(e) under the Securities Act of 1934, as amended (the "Exchange Act"), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of June 30, 2025, to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms, and include controls and procedures designed to ensure that information required to be disclosed by us in such reports is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosures.

**Changes in Internal Controls over Financial Reporting**

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

------

**PART II: OTHER INFORMATION**

***ITEM 1. LEGAL PROCEEDINGS***

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

Our Form 10-K for the fiscal year ended December 31, 2024 and Form 10-Q for the quarter ended March 31, 2025, and the Notes to AES Ohio's Financial Statements included therein, contain descriptions of certain legal proceedings in which we are or were involved. The information in or incorporated by reference into this Item 1 to Part II is limited to certain recent developments concerning our legal proceedings and new legal proceedings, since the filing of such Forms 10-K and 10-Q, and should be read in conjunction with such Forms 10-K and 10-Q.

The following information is incorporated by reference into this Item: information about the legal proceedings contained in PART I, ITEM 2. **–** *Management's Discussion and Analysis of Financial Condition and Results of Operations* and PART I, ITEM 1., Note 2. *Regulatory Matters* and Note 8. *Commitments and Contingencies* of AES Ohio's Condensed Financial Statements of this Quarterly Report on Form 10-Q.

***ITEM 1A. RISK FACTORS***

There have been no material changes to the risk factors disclosed in Item 1A. – Risk Factors of our Form 10-K. Additional risks and uncertainties also may adversely affect our business and operations, including those discussed in Item 2. – *Management's Discussion and Analysis of Financial Condition and Results of Operations* in this Form 10-Q.

***ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS***

As disclosed in further detail in Note 1 to the financial statements appearing elsewhere in this Quarterly Report on Form 10-Q, in a series of transactions that occurred in early April 2025 which were not registered under the Securities Act of 1933 as amended, in connection with an investment by a wholly-owned subsidiary of CDPQ, on April 2, 2025, DPL contributed to Ohio Holdings 41,172,173 shares, or 100%, of the issued and outstanding shares of common stock of AES Ohio. As a result of this transaction, Ohio Holdings owns 100% of the issued and outstanding shares of common stock of AES Ohio.

## Exhibit 10.1

**FIRST AMENDMENT <br>TO TERM LOAN AGREEMENT**

This First Amendment to Term Loan Agreement dated as of July 30, 2025 (this ***"Amendment"***), is entered into between THE DAYTON POWER & LIGHT COMPANY, an Ohio corporation doing business as AES Ohio (the ***"Borrower"***), the Lenders party hereto, and PNC BANK, NATIONAL ASSOCIATION, in its capacity as administrative agent for the Lenders (the ***"Administrative Agent"***).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A.&nbsp;&nbsp;&nbsp;&nbsp;Reference is made to that certain Term Loan Agreement dated as of August 14, 2024, by and among the Borrower, the Lenders, the Administrative Agent, PNC Capital Markets LLC, as Bookrunner and Joint Lead Arranger, and U.S. Bank, National Association, as Syndication Agent and Joint Lead Arranger (as amended, restated, supplemented, or otherwise modified from time to time, the ***"Loan Agreement"***).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.&nbsp;&nbsp;&nbsp;&nbsp;The Administrative Agent, the Lenders, and the Borrower have mutually agreed to extend the Term Loan Maturity Date subject to the terms and conditions contained herein.

The parties therefore agree as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.<u>Definitions</u>. Defined terms used but not defined in this Amendment are as defined in the Loan Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.<u>Amendment to Loan Agreement</u>. The Loan Agreement is hereby amended by amending and restating the definition of "Term Loan Maturity Date" in its entirety to read as follows:

"<u>Term Loan Maturity Date</u>" shall mean October 13, 2025, as such date may be extended pursuant to Section 11.1 [Modifications, Amendments or Waivers].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.<u>Reaffirmations</u>. The Borrower hereby reaffirms its obligations under the Loan Documents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.<u>Representations</u>. To induce the Administrative Agent and the Lenders to enter into this Amendment, the Borrower hereby represents to the Administrative Agent and the Lenders as follows:

(1)the Loan Agreement, as amended by this Amendment, is a legal, valid, and binding obligation of the Borrower, enforceable against the Borrower in accordance with its terms, except as enforceability is limited by bankruptcy, insolvency, or other similar laws of general application affecting the enforcement of creditors' rights or by general principles of equity limiting the availability of equitable remedies;

(2)the representation and warranties set forth in Section 6 of the Loan Agreement, as amended by this Amendment, are true and correct in all material respects (but if any representation or warranty is by its terms qualified by concepts of materiality, that representation or warranty is true and correct in all respects), in each case with the same effect as if such representations and warranties had been made on the date of this Amendment, with the exception that all references to the financial statements mean the financial statements most recently delivered to the

&nbsp;&nbsp;&nbsp;&nbsp;

------

Administrative Agent except for such changes as are specifically permitted under the Loan Agreement and except to the extent that any such representation or warranty expressly relates to an earlier date; and

(3)as of the date of this Amendment, after giving effect to this Amendment, (A) no Event of Default under Section 9 of the Loan Agreement has occurred and is continuing, and (B) no event or condition that, with the giving of notice or the passage of time, or both, would constitute an Event of Default, has occurred and is continuing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.<u>Conditions</u>. The effectiveness of this Amendment is subject to satisfaction of the following conditions:

(1)the Administrative Agent has received a copy of this Amendment, duly executed by all applicable Persons, in the form prepared by and acceptable to the Administrative Agent;

(2)the Borrower has paid to the Administrative Agent all fees and reasonable costs and expenses of the Administrative Agent in connection with the preparation of this Amendment and other related Loan Documents, including, without limitation, reasonable attorneys' fees; and

(3)all legal matters incident to the execution and delivery of this Amendment are satisfactory to the Administrative Agent and its counsel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.<u>Miscellaneous</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)This Amendment shall be deemed to be a contract under the Laws of the State of New York without regard to its conflict of laws principles. Sections 11.11(b) [Submission to Jurisdiction], 11.11(c) [Waiver of Venue], 11.11(d) [Service of Process] and 11.11(e) [Waiver of Jury Trial] are hereby incorporated by reference as if fully set forth herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)This Amendment binds the Borrower, the Administrative Agent and the Lenders and their respective successors and assigns, and will inure to the benefit of the Borrower, the Administrative Agent and the Lenders and the respective successors and assigns of the Administrative Agent and the Lenders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Except as specifically modified or amended by the terms of this Amendment, all other terms and provisions of the Loan Agreement and the other Loan Documents are incorporated by reference in this Amendment and in all respects continue in full force and effect. The Borrower, by execution of this Amendment, hereby reaffirms, assumes, and binds itself to all of the obligations, duties, rights, covenants, terms, and conditions that are contained in the Loan Agreement and the other Loan Documents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Each reference in the Loan Agreement to "this Agreement," "hereunder," "hereof," or words of like import, and each reference to the Loan Agreement in any and all instruments or documents delivered in connection therewith, will be deemed to refer to the Loan Agreement, as amended by this Amendment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)The Borrower shall pay all reasonable costs and expenses in connection with the preparation of this Amendment and other related loan documents, including, without limitation,

&nbsp;&nbsp;&nbsp;&nbsp;

------

reasonable attorneys' fees, and agrees to save the Administrative Agent harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such costs and expenses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)The parties may sign this Amendment in several counterparts, each of which will be deemed to be an original but all of which together will constitute one instrument.
