ITEM 1. BUSINESS
ITEM 1. BUSINESS
OVERVIEW
DPL is a regional energy company incorporated in 1985 under the laws of Ohio. All of DPL’s stock is owned by an AES subsidiary.
DPL has three primary subsidiaries: AES Ohio, MVIC and Miami Valley Lighting. AES Ohio is a public utility providing electric transmission and distribution services in West Central Ohio. For more information on the primary subsidiaries, see Note 1. Overview and Summary of Significant Accounting Policies of DPL's Consolidated Financial Statements and AES Ohio's Financial Statements. All of DPL's subsidiaries are wholly-owned. DPL manages its business through one reportable operating segment, the Utility segment. See Note 12. Business Segments of DPL's Consolidated Financial Statements for more information regarding DPL’s reportable segment. AES Ohio also manages its business through one reportable operating segment, the Utility segment.
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 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. AES Ohio also has a 4.9% interest in OVEC, an electric generating company. OVEC has two electric generating stations located in Cheshire, Ohio and Madison, Indiana with a combined generation capacity of 2,109 MW. AES Ohio’s share of this generation capacity is 103 MW. AES Ohio does not have any subsidiaries.
HUMAN CAPITAL MANAGEMENT
DPL's employees are essential to delivering and maintaining reliable service to our customers. DPL and its subsidiaries employed 707 people (650 full-time) at December 31, 2024, all of whom were employed by AES Ohio. Approximately 62% of all DPL employees are under a collective bargaining agreement that expires on October 31, 2026.

Safety
As part of AES, safety is one of our core values. Conducting safe operations at our facilities, so that each person can return home safely, is the cornerstone of our daily activities and decisions. Safety efforts are led globally by the AES Chief Operating Officer and supported by safety committees that operate at the local site level. Hazards in the workplace are actively identified and management tracks incidents so remedial actions can be taken to improve workplace safety.
We work with the Safety Management System (“SMS”), a global safety standard that applies to all AES employees and employees of AES subsidiaries, as well as contractors working in AES facilities and construction projects. The SMS requires continuous safety performance monitoring, risk assessment and performance of periodic integrated environmental, health and safety audits. The SMS provides a consistent framework for all AES operational businesses and construction projects to set expectations for risk identification and reduction, measure performance and drive continuous improvements. The SMS standard is consistent with the OHSA 18001/ISO 45001 standard. Our safety performance is also measured by both leading and lagging metrics. Our leading safety metrics track safety observations, safety meeting engagement and the reporting of lost time incident ("LTI") rates for our employees and contractors based on OSHA standards. Our lagging safety metrics track lost workday cases, severity rate, and recordable incidents. We are committed to excellence in safety and have implemented various programs to increase safety awareness and improve work practices.
Talent
We believe our success depends on our ability to attract, develop and retain key personnel. The skills, experience and industry knowledge of key employees significantly benefit our operations and performance. We have a comprehensive approach to managing our talent and developing our leaders in order to ensure our people have the right skills for today and tomorrow whether that requires us to build new business models or leverage leading technologies.
We emphasize employee development and training. To empower employees, we provide a range of development programs and opportunities, skills, and resources they need to be successful by focusing on experience and exposure, as well as formal programs including the AES ACE Academy for Talent Development, and our Trainee Program.
We believe that our individual differences make us stronger. Our Global Diversity and Inclusion Program is led by the AES Diversity and Inclusion Officer. Governance and standards are guided by the AES Chief Human Resources Officer, with input from members of AES' Global Leadership Team.
Compensation
Our compensation philosophy emphasizes pay-for-performance. Our incentive plans are designed to reward strong performance, with greater compensation paid when performance exceeds expectations and less compensation paid when performance falls below expectations. We invest significant time and resources to ensure our compensation programs are competitive and reward the performance of our people. Every year, our people who are not part of a collective bargaining agreement are eligible for an annual merit-based salary increase. In addition, individuals are eligible for a salary increase if they receive a significant promotion. For non-collectively bargained employees at certain levels in the organization, we offer annual incentives (bonus) and long-term compensation to reinforce the alignment between employees and AES.
SERVICE COMPANY
The Service Company provides services including operations, accounting, legal, human resources, information technology and other corporate services on behalf of certain AES U.S. companies including, among other companies, DPL and AES Ohio. The Service Company allocates the costs for these services based on cost drivers designed to result in fair and equitable allocations. This includes ensuring that the regulated utilities served, including AES Ohio, are not subsidizing costs incurred for the benefit of other businesses. See Note 11. Related Party Transactions of DPL's Consolidated Financial Statements and Note 10. Related Party Transactions of AES Ohio's Financial Statements.

SEASONALITY
The power delivery business is seasonal, and weather patterns have a material effect on energy demand. In the region we serve, demand for electricity is generally greater in the summer months associated with cooling and in the winter months associated with heating compared to other times of the year. AES Ohio's sales typically reflect the seasonal weather patterns but can also be impacted by service territory economic activity and the number of retail customers we have, as well as customer-initiated energy efficiency efforts.
Storm activity can also have an adverse effect on our operating performance. Severe storms often damage transmission and distribution equipment, thereby causing power outages, which reduce revenue and increase repair costs. Partially mitigating this impact is AES Ohio’s ability to timely recover certain O&M repair costs related to severe storms.
REGULATION AND MARKET STRUCTURE
Retail Rate Regulation
AES Ohio's distribution service to all retail customers as well as the provisions of its SSO service are regulated by the PUCO. In addition, certain costs are considered to be non-bypassable and are therefore assessed to all AES Ohio retail customers, under the regulatory authority of the PUCO, regardless of the customer’s retail electric supplier. AES Ohio's transmission rates are subject to regulation by the FERC under the Federal Power Act.
Ohio law establishes the process for determining SSO and non-bypassable rates charged by public utilities. Regulation of retail rates encompasses the timing of applications, the effective date of rate changes, the cost basis upon which the rates are set and other service-related matters. Ohio law also established the Office of the Ohio Consumers' Counsel, which has the authority to represent residential consumers in state and federal judicial and administrative rate proceedings.
Ohio legislation extends the jurisdiction of the PUCO to the records and accounts of certain public utility holding company systems, including DPL. The legislation extends the PUCO's supervisory powers to a holding company system's general condition and capitalization, among other matters, to the extent that such matters relate to the costs associated with the provision of public utility service. Based on existing PUCO and FERC authorization, regulatory assets and liabilities are recorded on the balance sheets of both DPL and AES Ohio.
For additional discussion of the regulatory environment related to our business, see the discussion in Note 2. Regulatory Matters of the Financial Statements included in Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K, which is incorporated by reference herein.
Ohio Retail Rates
AES Ohio rates for transmission and distribution electric service currently remain the lowest among Ohio investor-owned utilities.
On September 26, 2022, AES Ohio filed its latest ESP (ESP 4) with the PUCO. ESP 4 is a comprehensive plan to enhance and upgrade its network and improve service reliability, provide greater safeguards for price stability and continue investments in local economic development. On April 10, 2023, AES Ohio entered into a Stipulation and Recommendation with the PUCO Staff and seventeen parties (the “Settlement”) with respect to AES Ohio’s ESP 4 application, and, on August 9, 2023, the PUCO approved the Settlement without modification. With approval of this Settlement, the distribution rates that were approved by the PUCO on December 14, 2022, and are described in the paragraph below, became effective on September 1, 2023.
On December 14, 2022, the PUCO issued an order on AES Ohio's distribution rate case application that was filed on November 30, 2020. Among other matters, the order establishes a revenue increase of $75.6 million for AES Ohio’s base rates for electric distribution service and provides for a return on equity of 9.999% and a cost of long-term debt of 4.4% on a distribution rate base of $783.5 million and based on a capital structure of 53.87% equity and 46.13% long-term debt. These rates went into effect on September 1, 2023 with the approval of AES Ohio’s ESP 4.
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
On November 29, 2024, AES Ohio filed a new distribution rate case application with the PUCO. This rate case application proposes an increase to AES Ohio's annual distribution revenue requirement of $235.2 million, which incorporates certain investments that are currently recovered through the Distribution Investment Rider.
Ohio law and the PUCO rules contain targets relating to renewable energy standards. AES Ohio is currently in full compliance with renewable energy standards and recovers the costs of its compliance with Ohio renewable energy standards through its Standard Offer Rate Tariff, which is reviewed and audited by the PUCO.
The costs associated with providing high voltage transmission service and wholesale electric sales and ancillary services are subject to FERC jurisdiction. AES Ohio implemented a formula-based rate for its transmission service, effective May 3, 2020.
As a member of PJM, AES Ohio also receives revenue from the RTO related to AES Ohio’s transmission assets and incurs costs associated with its load obligations for retail customers. Ohio law includes a provision that would allow Ohio electric utilities to seek and obtain a reconcilable rider to recover RTO-related costs and credits. AES Ohio continues to recover non-market-based transmission and ancillary costs through its non-bypassable Transmission Cost Recovery Rider.
For more information regarding AES Ohio's ESP and distribution rate cases and other regulatory items, see Note 2. Regulatory Matters of the Financial Statements included in Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K.
Ohio Competition
Since January 2001, AES Ohio’s electric customers have been permitted to choose their retail electric generation supplier. The SSO generation supply is provided by third parties through a competitive bid process. AES Ohio continues to have the exclusive right to provide delivery service in its state-certified territory and the obligation to procure and provide electricity to SSO customers that do not choose an alternative supplier. The PUCO maintains jurisdiction over AES Ohio’s delivery of electricity, SSO and other retail electric services.
As part of Ohio’s electric deregulation law, all of the state’s investor-owned utilities were required to join an RTO. AES Ohio is a member of the PJM RTO. The role of the RTO is to administer a competitive wholesale market for electricity and ensure reliability of the transmission grid. PJM ensures the reliability of the high-voltage electric power system serving more than 65 million people in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia. PJM coordinates and directs the operation of the region’s transmission grid, administers the world’s largest competitive wholesale electricity market and plans regional transmission expansion improvements to maintain grid reliability and relieve congestion.
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; 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.
For further information about these risks, see Item 1A. - Risk Factors of this Annual Report on Form 10-K. Our operations are subject to significant government regulation and could be adversely affected by changes in the law or regulatory schemes; several of our businesses are subject to potentially significant remediation expenses, enforcement initiatives, private party lawsuits and reputational risk associated with CCR; our businesses are subject to stringent environmental laws, rules and regulations; and concerns about GHG emissions and the potential risks associated with climate change have led to increased regulation and other actions that could impact our businesses.
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
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 December 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.
From time to time, we are subject to enforcement actions for claims of noncompliance with environmental laws and regulations. DPL and AES Ohio cannot assure that they will be successful in defending against any claim of noncompliance. However, we do not believe any currently open environmental investigations will result in fines material to our results of operations, financial condition and cash flows.
Under certain environmental laws, we could be held responsible for costs relating to contamination at our past or present facilities and at third-party waste disposal sites. We could also be held liable for human exposure to hazardous substances or for other environmental damage. Our costs of complying with current and future environmental and health and safety laws, and our liabilities arising from past or future releases of, or exposure to, hazardous substances may adversely affect our business, results of operations, financial condition and cash flows. A discussion of the legislative and regulatory initiatives most likely to affect us follows.
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. These actions may have an impact on regulations that may affect our business, financial condition, or results of operations.
Environmental Matters Related to Air Quality
As a result of DPL’s sale of its ownership interest in the Miami Fort and Zimmer Stations in 2017, retirement and subsequent sale of its Stuart and Killen Stations in 2019, and the retirement and sale of our interest in Conesville in 2020, thereby completing the exit of our generation business, the following environmental matters, regulations and requirements are now not expected to have a material impact on DPL:
•the CAA and the following regulations:
◦CSAPR and associated updates;
◦MATS and any associated regulatory or judicial processes;
◦NAAQS; and
◦Greenhouse gas regulations established under CAA Section 111(d) for EGUs.
Environmental Matters Related to Water Quality, Waste Disposal and Ash Ponds
As a result of DPL’s sale of its ownership interest in the Miami Fort and Zimmer Stations, retirement and subsequent sale of its Stuart and Killen Stations, and the retirement and sale of our interest in Conesville, thereby completing the exit of our generation business, the following environmental matters, regulations and requirements are now not expected to have a material impact on DPL with respect to these generating stations (although certain other requirements related to water quality, waste disposal and ash ponds are discussed further below):
•water intake regulations, including those finalized by the EPA on May 19, 2014;
•revised technology-based regulations governing water discharges from steam electric generating facilities, finalized by the EPA on November 3, 2015 (and subsequently revised) and commonly referred to as the ELG rules; and
•Clean Water Act rules for selenium.
Notice of Potential Liability for Third Party Disposal Site
In December 2003, AES Ohio and other parties received notices that the EPA considered AES Ohio and other parties PRPs for the Tremont City Landfill site, located near Dayton, Ohio. On October 16, 2019, AES Ohio received another notice from the EPA claiming that AES Ohio is a PRP for the portion of the site known as the barrel fill.
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
While a review by AES Ohio of its records indicates that it did not contribute hazardous materials to the site, AES Ohio is currently unable to predict the outcome of this matter. If AES Ohio were required to contribute to the clean-up of the site, it could have an adverse effect on our business, financial condition or results of operations.
Regulation of Waste Disposal
In 2002, AES Ohio and other parties received a special notice that the EPA considered AES Ohio to be a PRP for the clean-up of hazardous substances at a third-party landfill known as the South Dayton Dump (“Landfill”). Several of the parties voluntarily accepted some of the responsibility for contamination at the Landfill and, in May 2010, three of those parties, Hobart Corporation, Kelsey-Hayes Company and NCR Corporation (“PRP Group”), filed a civil complaint in Ohio federal court (the “District Court”) against AES Ohio and numerous other defendants, alleging that the defendants contributed to the contamination at the landfill and were liable for contribution to the PRP group for costs associated with the investigation and remediation of the site.
While AES Ohio was able to get the initial case dismissed, the PRP Group subsequently, in 2013, entered into an additional Administrative Settlement Agreement and Order on Consent (“ASAOC”) with the EPA relating to vapor intrusion and again filed suit against AES Ohio and other defendants. Plaintiffs also added an additional ASAOC they entered into in 2016 pertaining to the investigation and remediation of all hazardous substances present in the Landfill - potentially including undefined areas outside the original dump footprint - to the vapor intrusion trial proceeding. The 2013 vapor intrusion ASAOC settled in early 2020, but the 2016 ASAOC remains to be adjudicated after completion of the remedial investigation feasibility study. While AES Ohio is unable to predict the outcome of these matters, if AES Ohio were required to contribute to the clean-up of the site, it could 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. It is too early to determine any potential impact from these revisions to the CCR Rule.
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
The CCR Rule, current or proposed amendments to, or EPA interpretations of, the CCR Rule, the results of groundwater monitoring data or the outcome of CCR-related litigation could have a material adverse effect on our results of operations, financial condition and cash flows.
Clean Water Act - Regulation of Water Discharge
On April 23, 2020, the U.S. Supreme Court issued a decision in the Hawaii Wildlife Fund v. County of Maui case related to whether a Clean Water Act permit is required when pollutants originate from a point source but are conveyed to navigable waters through a nonpoint source such as groundwater. The U.S. Supreme Court held that discharges to groundwater require a permit if the addition of the pollutants through groundwater is the functional equivalent of a direct discharge from the point source into navigable waters. A number of legal cases relevant to the determination of "functional equivalent" are ongoing in various jurisdictions. On November 27, 2023, the EPA issued draft guidance regarding functional equivalent discharge. It is too early to determine whether the Supreme Court decision or the result of litigation related to "functional equivalent" may have a material adverse effect on our results of operations, financial condition and cash flows.
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 water are 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. 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.
Climate Change Legislation and Regulation
Although we have exited our generation business, our continuing operations face certain risks related to existing and potential international, federal, state, regional and local GHG legislation and regulations, including risks related to increased capital expenditures or other compliance costs which could have a material adverse effect on our results of operations, financial condition and cash flows. Except as noted in the discussion below, at this time, we cannot estimate the costs of compliance with existing, proposed or potential international, federal, state or regional GHG emissions reductions legislation or initiatives due in part to the fact that many of these proposals are in earlier stages of development and any final laws or regulations, if adopted, could vary drastically from current proposals. Any international, federal, state or regional legislation adopted in the U.S. that would require the reduction of GHG emissions could have a material adverse effect on our results of operations, financial condition and cash flows.
On the international level, on December 12, 2015, 195 nations, including the U.S., finalized the text of an
international climate change accord in Paris, France (the “Paris Agreement”), which agreement was signed and officially entered into on April 22, 2016. The Paris Agreement calls for countries to set their own GHG emissions targets, make these emissions targets more stringent over time and be transparent about the GHG emissions reporting and the measures each country will use to achieve its GHG emissions targets. A long-term goal of the Paris Agreement is to limit global temperature increase to well below two degrees Celsius from temperatures in the pre-industrial era. The U.S. withdrawal from the Paris Agreement became effective on November 4, 2020. However, on January 20, 2021, President Biden signed and submitted an instrument for the U.S. to rejoin the Paris Agreement, which became effective on February 19, 2021. On January 20, 2025, President Trump issued an Executive Order titled “Putting America First in International Environmental Agreements” directing the U.S. Ambassador to the United Nations to formally withdraw from the Paris Agreement. The international community has and continues to gather annually for the Conference to the Parties on the UN Framework Convention on Climate.

ITEM 1A. RISK FACTORS
ITEM 1A. RISK FACTORS
Investors should consider carefully the following risk factors that could cause our business, operating results and financial condition to be materially adversely affected. New risks may emerge at any time, and we cannot predict those risks or estimate the extent to which they may affect our business or financial performance. The categories of risk we have identified in this item include risks associated with our operations, governmental regulation and laws and our indebtedness and financial condition. These risk factors should be read in conjunction with the other detailed information concerning DPL set forth in the DPL's Consolidated Financial Statements and concerning AES Ohio set forth in the AES Ohio's Financial Statements in Item 8. - Financial Statements and Supplementary Data and more information in Item 7. - Management's Discussion and Analysis of Financial Condition and Results of Operations herein. The risks and uncertainties described below are not the only ones that we face.
RISKS ASSOCIATED WITH OUR OPERATIONS
We may be negatively affected by a lack of growth or a decline in the number of customers.
Customer growth is affected by a number of factors outside our control, such as population changes, job and income growth, housing starts, new business formation and the overall level of economic activity. A significant lack of growth, or decline, in the number of customers in our service territory could have a material adverse effect on our results of operations, financial condition and cash flows and may cause us to fail to fully realize anticipated benefits from investments and expenditures.
Our business is sensitive to weather and seasonal variations.
Weather conditions significantly affect the demand for electric power and, accordingly, our business is affected by variations in general weather conditions and unusually severe weather. As a result of these factors, our operating revenue and associated operating expenses are not generated evenly by month during the year. We forecast electric sales based on normal weather, which represents a long-term historical average. Significant variations from normal weather (such as warmer winters and cooler summers) could have a material impact on our revenue, operating income and net income and cash flows. In addition, severe or unusual weather, such as floods, tornadoes and ice or snowstorms, may cause outages and property damage that may require us to incur additional costs that may not be insured or recoverable from customers. While AES Ohio is permitted to seek recovery of storm damage costs, if AES Ohio is unable to fully recover such costs in a timely manner, it could have a material adverse effect on our results of operations, financial condition and cash flows.
Our membership in an RTO presents risks that could have a material adverse effect on our results of operations, financial condition and cash flows.
On October 1, 2004, in compliance with Ohio law, AES Ohio turned over control of its transmission functions and fully integrated into PJM, an RTO.
The rules governing the various regional power markets may also change from time to time which could affect our costs and revenue and have a material adverse effect on our results of operations, financial condition and cash flows. We may be required to expand our transmission system according to decisions made by PJM rather than our internal planning process. Various proposals and proceedings before the FERC may cause transmission rates to change from time to time. In addition, PJM developed and continues to refine rules associated with the allocation and methodology of assigning costs associated with improved transmission reliability, reduced transmission
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
congestion and firm transmission rights that may have a financial effect on us. We also incur fees and costs to participate in PJM.
Non-market-based RTO-related charges are being recovered from all retail customers through the Transmission Rider. If in the future, however, we are unable to recover all of these costs in a timely manner this could have a material adverse effect on our results of operations, financial condition and cash flows.
As a member of PJM, AES Ohio is also subject to certain additional risks including those associated with the allocation of losses caused by unreimbursed defaults of other participants in PJM markets among PJM members and those associated with complaint cases filed against PJM that may seek refunds of revenue previously earned by PJM members including AES Ohio. These amounts could be significant and have a material adverse effect on our results of operations, financial condition and cash flows.
Costs associated with new transmission projects could have a material adverse effect on our results of operations, financial condition and cash flows.
Annually, PJM performs a review of the capital additions required to provide reliable electric transmission services throughout its territory. PJM traditionally allocated the costs of constructing these facilities to those entities that benefited directly from the additions. Over the last several years, however, some of the costs of constructing large, new transmission facilities have been “socialized” across PJM without a direct relationship between the costs assigned to and benefits received by particular PJM members. To date, the additional costs charged to AES Ohio for large, new transmission approved projects have not been material. Over time, as more new transmission projects are constructed and if the allocation method is not changed, the annual costs could become material. AES Ohio is recovering the Ohio retail jurisdictional share of these allocated costs from its retail customers through the Transmission Rider. To the extent that any costs in the future are material and we are unable to recover them from our customers, such costs could have a material adverse effect on our results of operations, financial condition and cash flows.
Our transmission and distribution system is subject to operational, reliability and capacity risks.
The ongoing reliable performance of our transmission and distribution system is subject to risks due to, among other things, weather damage, intentional or unintentional damage, equipment or process failure, catastrophic events, such as fires and/or explosions, facility outages, labor disputes, accidents or injuries, operator error or inoperability of key infrastructure internal or external to us and events occurring on third party systems that interconnect to and affect our system. The failure of our transmission and distribution system to fully operate and deliver the energy demanded by customers could have a material adverse effect on our results of operations, financial condition and cash flows, and if such failures occur frequently and/or for extended periods of time, could result in adverse regulatory action. In addition, the advent and quick adoption of new products and services that require increased levels of electrical energy cannot be predicted and could result in insufficient transmission and distribution system capacity timely enough to accommodate the potential increased demand. Also, as a result of the above risks and other potential risks and hazards associated with transmission and distribution operations, we may from time to time become exposed to significant liabilities for which we may not have adequate insurance coverage. We maintain an amount of insurance protection that we believe is adequate, but there can be no assurance that our insurance will be sufficient or effective under all circumstances and against all hazards or liabilities to which we may be subject. Further, any increased costs or adverse changes in the insurance markets may cause delays or inability in maintaining insurance coverage on terms similar to those presently available to us or at all. A successful claim for which we are not fully insured could have a material adverse effect on our results of operations, financial condition and cash flows.
Current and future conditions in the economy may adversely affect our customers, suppliers and other counterparties in a way which could materially and adversely affect our results of operations, financial condition and cash flows.
Our business, results of operations, financial condition and cash flows have been and will continue to be affected by general economic conditions. Slowing economic growth, credit market conditions, fluctuating consumer and business confidence, fluctuating commodity prices and other challenges currently affecting the general economy, have caused and may continue to cause some of our customers to experience deterioration of their businesses,
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
cash flow shortages and difficulty obtaining financing. As a result, existing customers may reduce their electricity consumption and may not be able to fulfill their payment obligations to us in a normal, timely fashion. In addition, some existing commercial and industrial customers may discontinue their operations. Sustained downturns, recessions or a sluggish economy generally affect the markets in which we operate and negatively influence our energy operations. A contracting, slow or sluggish economy could reduce the demand for energy in areas in which we are doing business. For example, during economic downturns, our commercial and industrial customers may see a decrease in demand for their products, which in turn may lead to a decrease in the amount of energy they require. Furthermore, projects which may result in potential new customers may be delayed until economic conditions improve. Some of our suppliers, customers, other counterparties and others with whom we transact business experience financial difficulties, which may impact their ability to fulfill their obligations to us. For example, our counterparties on forward purchase contracts and financial institutions involved in our credit facility may become unable to fulfill their contractual obligations to us or result in their declaring bankruptcy or similar insolvency-like proceedings. We may not be able to enter into replacement agreements on terms as favorable as our existing agreements. Reduced demand for our electric services, failure by our customers to timely remit full payment owed to us and supply delays or unavailability could have a material adverse effect on our results of operations, financial condition and cash flows. In particular, the projected economic growth and total employment in AES Ohio’s service territory are important to the realization of our forecasts for annual energy sales.
Economic conditions relating to the asset performance and interest rates of our pension and postemployment benefit plans could materially and adversely impact our results of operations, financial condition and cash flows.
Pension costs are based upon a number of actuarial assumptions, including an expected long-term rate of return on pension plan assets, level of employer contributions, the expected life span of pension plan beneficiaries and the discount rate used to determine the present value of future pension obligations. Any of these assumptions could prove to be wrong, resulting in a shortfall of our pension and postemployment benefit plan assets compared to obligations under our pension and postemployment benefit plans. Further, the performance of the capital markets affects the values of the assets that are held in trust to satisfy future obligations under our pension and postemployment benefit plans. These assets are subject to market fluctuations and will yield uncertain returns, which may fall below our projected return rates. A decline in the market value of the pension and postemployment benefit plan assets will increase the funding requirements under our pension and postemployment benefit plans if the actual asset returns do not recover these declines in value in the foreseeable future. Future pension funding requirements, and the timing of funding payments, may also be subject to changes in legislation. We are responsible for funding any shortfall of our pension and postemployment benefit plans’ assets compared to obligations under the pension and postemployment benefit plans, and a significant increase in our pension liabilities could materially and adversely impact our results of operations, financial condition and cash flows. We are subject to the Pension Protection Act of 2006, which requires underfunded pension plans to improve their funding ratios within prescribed intervals based on the level of their underfunding. As a result, our required contributions to these plans, at times, have increased and may increase in the future. In addition, our pension and postemployment benefit plan liabilities are sensitive to changes in interest rates. When interest rates decrease, the discounted liabilities increase benefit expense and funding requirements. Further, changes in demographics, including increased numbers of retirements or changes in life expectancy assumptions, may also increase the funding requirements for the obligations related to the pension and other postemployment benefit plans. See Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Estimates - Pension Plans and for more information, see Note 8. Benefit Plans of DPL's Consolidated Financial Statements and Note 7. Benefit Plans of AES Ohio's Financial Statements included in Item 8. Financial Statements and Supplementary Data. Declines in market values and increased funding requirements could have a material adverse effect on our results of operations, financial condition and cash flows.
Counterparties providing materials or services may fail to perform their obligations, which could materially and adversely impact our results of operations, financial condition and cash flows.
We enter into transactions with and rely on many counterparties in connection with our business, including for purchased power, for our capital improvements and additions and to provide professional services, such as actuarial calculations, payroll processing and various consulting services. If any of these counterparties fails to perform its obligations to us or becomes unavailable, our business plans may be materially disrupted, we may be forced to discontinue certain operations if a cost-effective alternative is not readily available or we may be forced to enter into
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
alternative arrangements at then-current market prices that may exceed our contractual prices and cause delays. Although our agreements are designed to mitigate the consequences of a potential default by the counterparty, our actual exposure may be greater than relief provided by these mitigation provisions. Any of the foregoing could result in regulatory actions, cost overruns, delays or other losses, any of which (or a combination of which) could have a material adverse effect on our results of operations, financial condition and cash flows.
Further, our construction program calls for extensive expenditures for capital improvements and additions, including the installation of upgrades, additions and improvements to transmission and distribution facilities, as well as other initiatives. As a result, we may engage contractors and enter into agreements to acquire necessary materials and/or obtain required construction related services. In addition, some contracts may provide for us to assume the risk of price escalation and availability of certain metals and key components. This could force us to enter into alternative arrangements at then-current market prices that may exceed our contractual prices or cause construction delays in a significant manner. It could also subject us to enforcement action by regulatory authorities to the extent that such a contractor failure resulted in a failure by AES Ohio to comply with requirements or expectations, particularly with regard to the cost of the project. If these events were to occur, we might incur losses or delays in completing construction.
Highly infectious or contagious disease outbreaks could impact our business and operations.
Regional or global outbreaks of infectious or contagious diseases, such as COVID-19 or another pandemic could have material and adverse effects on our results of operations, financial condition and cash flows due to, among other factors:
•decline in customer demand as a result of general decline in business activity;
•destabilization of the markets and decline in business activity negatively impacting our customer growth or the number of customers in our service territory as well as our customers’ ability to pay for our services when due (or at all);
•delay or inability in obtaining regulatory actions and outcomes that could be material to our business, including for recovery of COVID-19 related expenses and losses such as uncollectible customer amounts and the review and approval of our applications, rates and charges by the PUCO;
•difficulty accessing the capital and credit markets on favorable terms, or at all, a disruption and instability in the global financial markets, or deteriorations in credit and financing conditions which could affect our access to capital necessary to fund business operations or address maturing liabilities on a timely basis;
•negative impacts on the health of our essential personnel, especially if a significant number of them are affected, and on our operations as a result of implementing stay-at-home, quarantine and other social distancing measures;
•a deterioration in our ability to ensure business continuity during a disruption, including increased cybersecurity attacks related to a work-from-home environment;
•delays or inability to access, transport and deliver materials to our facilities due to restrictions on business operations or other factors affecting us and our third-party suppliers;
•delays or inability to access equipment or the availability of personnel to perform planned and unplanned maintenance, which can, in turn, lead to disruption in operations;
•delays or inability in achieving our financial goals, growth strategy and digital transformation; and
•delays in the implementation of expected rules and regulations.
Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations, reputation and prospects.
Failure to maintain an effective system of internal controls over financial reporting could result in material misstatements in our financial statements, the disallowance of cost recovery, or incorrect payment processing.
Our internal controls, accounting policies and practices and internal information systems are designed to enable us to capture and process transactions and information in a timely and accurate manner in compliance with GAAP in the United States of America, laws and regulations, taxation requirements and federal securities laws and regulations in order to, among other things, disclose and report financial and other information in connection with
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
the recovery of our costs and with our reporting requirements under federal securities, tax and other laws and regulations and to properly process payments. We have also implemented corporate governance, internal control and accounting policies and procedures in connection with the Sarbanes-Oxley Act of 2002. Our internal controls and policies have been and continue to be closely monitored by management and our Board of Directors. While we believe these controls, policies, practices and systems are adequate to verify data integrity, the identification of significant deficiencies or material weaknesses in our internal controls that we cannot remediate in a timely manner could lead to undetected errors that could result in material misstatements in our financial statements, the disallowance of cost recovery, or incorrect payment processing. The consequences of these events could have a material adverse effect on our results of operations, financial condition and cash flows.
If we are unable to maintain a qualified and properly motivated workforce, it could have a material adverse effect on our results of operations, financial condition and cash flows.
One of the challenges we face is to retain a skilled, efficient and cost-effective workforce while recruiting new talent to replace losses in knowledge and skills due to resignations, terminations or retirements. This undertaking could require us to make additional financial commitments and incur increased costs. If we are unable to successfully attract and retain an appropriately qualified workforce, it could have a material adverse effect on our results of operations, financial condition and cash flows. In addition, we have employee compensation plans that reward the performance of our employees. We seek to ensure that our compensation plans encourage acceptable levels for risk and high performance through pay mix, performance metrics and timing. We may not be able to successfully train new personnel as current workers with significant knowledge and expertise retire. We also may be unable to staff our business with qualified personnel in the event of significant absenteeism related to a pandemic illness. Excessive risk-taking by our employees to achieve performance targets, through mitigated by policies and procedures, could result in events that have a material adverse effect on our results of operations, financial condition and cash flows.
We are subject to collective bargaining agreements that could adversely affect our business, results of operations, financial condition and cash flows.
We are subject to collective bargaining agreements with employees who are members of a union. Over half of our employees are represented by a collective bargaining agreement. While we believe that we maintain a satisfactory relationship with our employees, it is possible that labor disruptions affecting some or all of our operations could occur during the period of the collective bargaining agreement or at the expiration of the collective bargaining agreement before a new agreement is negotiated. Work stoppages by, or poor relations or ineffective negotiations with, our employees or other workforce issues could have a material adverse effect on our results of operations, financial condition and cash flows.
The use of non-derivative and derivative instruments in the normal course of business could result in losses that could materially and adversely impact our results of operations, financial position and cash flows.
We sometimes use non-derivative and derivative instruments, such as swaps, options, futures and forwards, to manage financial risks. These trades are affected by a range of factors, including fluctuations in interest rates and optimization opportunities. We have attempted to manage our commodities price risk exposure by establishing and enforcing risk limits and risk management policies. Despite our efforts, however, these risk limits and management policies may not work as planned and fluctuating prices and other events could adversely affect our results of operations, financial condition and cash flows. In the absence of actively quoted market prices and pricing information from external sources, the valuation of these instruments can involve management’s judgment or the use of estimates. As a result, changes in the underlying assumptions or use of alternative valuation methods could affect the reported fair value of some of these contracts. We could also recognize financial losses as a result of volatility in the market values of these contracts, a counterparty failing to perform or the underlying transactions which the instruments are intended to hedge failing to materialize, which could result in a material adverse effect on our results of operations, financial condition and cash flows.
DPL Inc. and AES Ohio

Cyber attacks and data security breaches could harm our business
Our business relies on electronic systems and network technologies to operate our transmission and distribution infrastructure. We also use various financial, accounting and other infrastructure systems. We also store and use customer, employee, and other personal information and other confidential and sensitive information. Our infrastructure may be targeted by nation states, hacktivists, criminals, insiders or terrorist groups. In particular, there has been an increased focus on the U.S. energy grid believed to be related to the Russia/Ukraine conflict. Such an attack, by hacking, malware or other means, may interrupt our operations, cause property damage, affect our ability to control our infrastructure assets, cause the release of sensitive customer information or limit communications with third parties. Any loss or corruption of confidential or proprietary data through a breach of our systems or certain of our third party vendor systems may:
•impact our operations, revenue, strategic objectives, customer and vendor relationships;
•expose us to negative publicity, legal claims, regulatory investigations and proceedings and associated penalties or liabilities;
•require extensive repair and restoration costs for additional security measures to avert future attacks;
•impair our reputation and limit our competitiveness for future opportunities; and
•impact our financial and accounting systems and, subsequently, our ability to correctly record, process and report financial information.
We have implemented measures to help prevent unauthorized access to our systems and facilities, including certain measures to comply with mandatory regulatory reliability standards.
To date, cyber breaches have not had a material impact on our operations or financial results. We continue to assess potential threats and vulnerabilities and make investments to address them, including global monitoring of networks and systems, identifying and implementing new technology, improving user awareness through employee security training, and updating our security policies as well as those for third-party providers.
We cannot guarantee the extent to which our security measures will prevent future cyber attacks and security breaches or that our insurance coverage will adequately cover any losses we may experience.
See ITEM 1C. CYBERSECURITY for additional information.
Failure or disruption in our information systems or those of businesses we rely on, or implementation of new processes and information systems could, if significant, interrupt our operations and adversely affect our business, results of operations, financial condition and cash flows in a material manner.
Our business depends on numerous information systems to manage our operations and business processes, financial information, and customer billings. From time to time, we have experienced, and may in the future experience, damage or disruptions in our information technology and computer systems from various risks including, but not limited to, power outages, facility damage, computer and telecommunications failures, computer viruses, security breaches, vandalism, theft, natural disasters, catastrophic events, human error and potential cyber threats, and our disaster recovery planning cannot account for all eventualities.
In addition, we are currently making, and expect to continue to make, investments in our information technology systems and infrastructure, some of which are significant. In 2024, we implemented certain replacement information systems, including our customer information and billing system. Failure to manage the ongoing implementations associated with this initiative, including with respect to our systems for billing and collecting from our customers, could, if significant, result in a material adverse effect on our results of operations, financial condition and cash flows.
DPL Inc. and AES Ohio

RISKS ASSOCIATED WITH GOVERNMENTAL REGULATION AND LAWS
We may not always be able to recover our costs to deliver electricity to our retail customers. The costs we can recover and the return on capital we are permitted to earn for the most substantial part of our business are regulated and governed by the laws of Ohio and the rules, policies and procedures of the PUCO.
In Ohio, transmission and distribution businesses are regulated. Even though rate regulation is premised on full recovery of prudently incurred costs and a reasonable rate of return on invested capital, there can be no assurance that the PUCO will agree that all of our costs have been prudently incurred or are recoverable. There can be no assurance that the regulatory process in which rates are determined will always result in rates that will produce a full or timely recovery of our costs or permitted rates of return. Accordingly, the revenue AES Ohio receives may or may not match its expenses at any given time.
Changes in or reinterpretations of, or the unexpected application of the laws, rules, policies and procedures that set or govern electric rates, permitted rates of return, rate structures, operation of a competitive bid structure to supply retail generation service to SSO customers, reliability initiatives, capital expenditures and investments and the recovery of these and other costs on a full or timely basis through rates, power market prices and the frequency and timing of rate increases, could have a material adverse effect on our results of operations, financial condition and cash flows.
Our increased costs due to renewable energy requirements may not be fully recoverable in the future.
The renewable energy standards have increased our costs and are expected to continue to increase (and could materially increase) these costs. AES Ohio is currently entitled to recover costs associated with its renewable energy compliance. If, in the future, we are unable to timely or fully recover these costs, it could have a material adverse effect on our results of operations, financial condition and cash flows. In addition, if we were found not to be in compliance with these standards, monetary penalties could apply. These penalties are not permitted to be recovered from customers and significant penalties could have a material adverse effect on our results of operations, financial condition and cash flows.
We are subject to numerous environmental laws, rules and regulations that require capital expenditures, increase our cost of operations and may expose us to environmental liabilities.
We are subject to various federal, state, regional and local environmental protection and health and safety laws and regulations governing, among other things, the remediation of retired generation and other facilities, storage, handling, use, storage, disposal and transportation of coal combustion residuals and other materials, some of which may be defined as hazardous materials, the emission and discharge of hazardous and other materials or items into the environment, such as GHGs; and the health and safety of our employees. Such laws, rules and regulations can become stricter over time, and we could also become subject to additional environmental laws, rules and regulations and other requirements in the future. Environmental laws, rules and regulations also require us to comply with inspections and obtain and comply with a wide variety of environmental licenses, permits, inspections and other governmental authorizations. These laws, rules and regulations often require a lengthy and complex process of obtaining and renewing licenses, permits and other governmental authorizations from federal, state and local agencies. If we are not able to timely comply with inspections and obtain, maintain or comply with all environmental laws, rules and regulations and all licenses, permits and other government authorizations required to operate our business, then our operations could be prevented, delayed or subject to additional costs. A violation of environmental laws, rules, regulations, licenses, permits or other requirements can result in substantial fines, penalties, other sanctions, permit revocation, facility shutdowns, the imposition of stricter environmental standards and controls or other injunctive measures affecting operating assets. In addition, any actual or alleged violation of these laws, rules or regulations and other requirements may require us to expend significant resources to defend against any such actual or alleged violations. AES Ohio has an ownership interest in OVEC, which operates generating stations. We generally are responsible for our respective pro rata share of expenditures for complying with environmental laws, rules, regulations, licenses, permits and other requirements at this generating station, but have limited control over the compliance measures taken by the operator. Under certain environmental laws, we could also be held strictly, jointly and severally responsible for costs relating to contamination at our past or present facilities and at third-party waste disposal sites. We could also be held liable for human exposure to such hazardous substances or for other environmental damage.
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
In particular, we are subject to potentially significant remediation expenses, enforcement initiatives, private-party lawsuits and reputational risk associated with CCR, which consists of bottom ash, fly ash, boiler slag and flue gas desulfurization materials generated from burning coal generated at our formerly owned coal-fired generation plant sites. CCR currently remains onsite at OVEC's facilities, including in CCR ponds. Compliance with the CCR rule, amendments to the federal CCR rule, or other federal, state, or foreign rules or programs addressing CCR may require us to incur substantial costs. In addition, CCR, particularly with respect to its beneficial use and regulation as nonhazardous solid waste, has been the subject of interest from environmental non-governmental organizations and the media. Any of the foregoing could have a material adverse effect on our results of operations, financial condition and cash flows.
From time to time we are subject to enforcement and litigation actions for claims of noncompliance with environmental laws, rules and regulations or other environmental requirements. We cannot assure that we will be successful in defending against any claim of noncompliance. Any actual or alleged violation of these laws, rules, regulations and other requirements may require us to expend significant resources to defend against any such actual or alleged violations and expose us to unexpected costs. Our costs and liabilities relating to environmental matters could have a material adverse effect on our results of operations, financial condition and cash flows. See Item 1. - Business - Environmental Matters for a more comprehensive discussion of these and other environmental matters impacting us.
Concerns about GHG emissions and the potential risks associated with climate change have led to increased regulation and other actions that could impact our business.
Although we have exited our generation business, our continuing operations face risks from regulatory developments related to climate change, as well as the physical impacts of climate change. At the federal, state and regional levels, policies are under development or have been developed to regulate GHG emissions. There currently is no U.S. federal legislation imposing mandatory GHG emission reductions (including for CO2) that affects our current operations.
In December 2015, the parties to the United Nations Framework Convention on Climate Change convened for the 21st Conference of the parties and the resulting Paris Agreement established a long-term goal of keeping the increase in global average temperature well below 2°C above pre-industrial levels. The international community has and continues to gather annually for Conference to the Parties of the United Nations Framework Convention on Climate Change. We anticipate that the Paris Agreement will continue the trend toward efforts to de-carbonize the global economy. The U.S. withdrawal from the Paris Agreement became effective on November 4, 2020. On January 20, 2021, President Biden signed and submitted an instrument for the U.S. to rejoin the Paris Agreement, which, became effective for the U.S. on February 19, 2021. On January 20, 2025, President Trump issued an Executive Order titled “Putting America First in International Environmental Agreements” directing the U.S. Ambassador to the United Nations to formally withdraw from the Paris Agreement.
Any existing or future international, federal, state or regional legislation or regulation of GHG emissions, to the extent directly or indirectly applicable to our electric transmission and distribution operations, could have a material adverse impact on our financial performance.
Furthermore, according to the Intergovernmental Panel on Climate Change, physical risks from climate change could include, but are not limited to, increased runoff and earlier spring peak discharge in many glacier and snow-fed rivers, warming of lakes and rivers, an increase in sea level, changes and variability in precipitation and in the intensity and frequency of extreme weather events. Physical impacts may have the potential to significantly affect our business and operations. For example, extreme weather events could result in increased downtime and operation and maintenance costs at our electric power transmission and distribution assets and facilities. Variations in weather conditions, primarily temperature and humidity, would also be expected to affect the energy needs of customers. A decrease in energy consumption could decrease our revenue. In addition, while revenue would be expected to increase if the energy consumption of customers increased, such increase could prompt the need for additional investment in generation capacity.
If any of the foregoing risks materialize, we expect our costs to increase or revenue to decrease and there could be a material adverse effect on our business and on our consolidated results of operations, financial condition, cash
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
flows and reputation if such changes are significant. Please see Item 1. - Business - Environmental Matters for more information of environmental matters impacting us, including those relating to regulation of GHG emissions.
If we were found not to be in compliance with the mandatory reliability standards, we could be subject to sanctions, including substantial monetary penalties, which likely would not be recoverable from customers through regulated rates.
As an owner of a bulk power transmission system, AES Ohio is subject to mandatory reliability standards promulgated by the NERC and enforced by the FERC. The standards are based on the functions that need to be performed to ensure the bulk power system operates reliably and is guided by reliability and market interface principles. In addition, AES Ohio is subject to Ohio reliability standards and targets. Compliance with reliability standards may subject us to higher operating costs or increased capital expenditures. Although we expect to recover costs and expenditures from customers through regulated rates, there can be no assurance that the PUCO will approve full recovery in a timely manner. If we were found not to be in compliance with the mandatory reliability standards, we could be subject to sanctions, including substantial monetary penalties, which could have a material adverse effect on our results of operations, financial condition and cash flows.
We are subject to extensive laws and local, state and federal regulation, as well as litigation and other proceedings that affect our operations and costs.
We are subject to extensive regulation at the federal, state, and local levels. For example, at the federal level, AES Ohio is regulated by the FERC and the NERC and, at the state level, by the PUCO. The regulatory power of the PUCO over AES Ohio is both comprehensive and typical of the traditional form of regulation generally imposed by state public utility commissions. We face the risk of unexpected or adverse regulatory action. Regulatory discretion is reasonably broad in Ohio. AES Ohio is subject to regulation by the PUCO as to our services and facilities, the valuation of property, the construction, purchase, or lease of electric facilities, the classification of accounts, rates of depreciation, the increase or decrease in retail rates and charges, the issuance of securities and incurrence of debt, the acquisition and sale of some public utility properties or securities and certain other matters. As a result of the Energy Policy Act of 2005 and subsequent legislation affecting the electric utility industry, we have been required to comply with rules and regulations in areas including mandatory reliability standards, cybersecurity, transmission expansion and energy efficiency. Complying with the regulatory environment to which we are subject requires us to expend a significant amount of funds and resources. The failure to comply with this regulatory environment could subject us to substantial financial costs and penalties and changes, either forced or voluntary, in the way we operate our business that could have a material adverse effect on our results of operations, financial condition and cash flows.
We are subject to litigation, regulatory proceedings, administrative proceedings, audits, settlements, investigations and claims from time to time that require us to expend significant funds to address. There can be no assurance that the outcome of these matters will not have a material adverse effect on our business, results of operations, financial condition and cash flows. Asbestos and other regulated substances are, and may continue to be, present at our facilities, and we have been named as a defendant in asbestos litigation. The continued presence of asbestos and other regulated substances at these facilities could result in additional litigation being brought against us, which could have a material adverse effect on our results of operations, financial condition and cash flows. See Item 1. - Business - Regulation And Market Structure, Item 1. - Business - Environmental Matters, and Item 3. - Legal Proceedings for a summary of significant regulatory matters and legal proceedings involving us.
See Note 2. Regulatory Matters and Note 10. Contractual Obligations, Commercial Commitments and Contingencies of DPL's Consolidated Financial Statements and Note 2. Regulatory Matters and Note 9. Contractual Obligations, Commercial Commitments and Contingencies of AES Ohio's Financial Statements included in Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K for a summary of significant regulatory matters and legal proceedings involving us.
Tax legislation initiatives or challenges to our tax positions could adversely affect our operations and financial condition.
We are subject to the tax laws and regulations of the U.S. federal, state and local governments. From time to time, legislative measures may be enacted that could adversely affect our overall tax positions regarding income or other
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
taxes. There can be no assurance that our effective tax rate or tax payments will not be adversely affected by these legislative measures. In addition, U.S. federal, state and local tax laws and regulations are extremely complex and subject to varying interpretations. There can be no assurance that our tax positions will be sustained if challenged by relevant tax authorities and if not sustained, there could be a material adverse effect on our results of operations, financial condition and cash flows.
RISKS RELATED TO OUR INDEBTEDNESS AND FINANCIAL CONDITION
The level of our indebtedness, and the security provided for this indebtedness, could adversely affect our financial flexibility, and a material change in market interest rates could adversely affect our results of operations, financial condition and cash flows.
As of December 31, 2024, the carrying value of DPL's debt was $2,129.4 million and the carrying value of AES Ohio's debt was $1,302.3 million. Of AES Ohio's indebtedness, there was $1,005.0 million of First Mortgage Bonds as of December 31, 2024, which are secured by the pledge of substantially all of the assets of AES Ohio under the terms of AES Ohio’s First and Refunding Mortgage. This level of indebtedness and related security has important consequences, including:
•increasing our vulnerability to general adverse economic and industry conditions;
•requiring us to dedicate a substantial portion of our cash flow from operations to make payments on our indebtedness, thereby reducing the availability of our cash flow to fund other corporate purposes;
•limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and
•limiting, along with the financial and other restrictive covenants in our indebtedness, our ability to borrow additional funds, as needed.
If AES Ohio issues additional debt in the future, we will be subject to the terms of such debt agreements and be required to obtain regulatory approvals. To the extent we increase our leverage, the risks described above would also increase. Further, actual cash requirements in the future may be greater than expected. Accordingly, our cash flows from operations may not be sufficient to repay all of the outstanding debt as it becomes due and, in that event, we may not be able to borrow money, sell assets or otherwise raise funds on acceptable terms, or at all, to refinance our debt as it becomes due. Additionally, any failure to comply with covenants in the instruments governing our debt could result in an event of default thereunder. For further discussion of our outstanding debt obligations, see Item 7. - Management's Discussion and Analysis of Financial Condition and Results of Operations - Capital Resources and Liquidity and Note 6. Debt of DPL's Consolidated Financial Statements and Note 5. Debt of AES Ohio's Financial Statements included in Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K.
AES Ohio has variable rate debt that bears interest based on a prevailing rate that is reset based on a market index that can be affected by market demand, supply, market interest rates and other market conditions. We also maintain both cash on deposit and investments in cash equivalents from time to time that could be impacted by interest rate fluctuations. As such, any event which impacts market interest rates could have a material effect on our results of operations, financial condition and cash flows. In addition, rating agencies issue ratings on our credit and our debt that affect our borrowing costs under our financial arrangements and affect our potential pool of investors and funding sources. Credit ratings also govern the collateral provisions of certain of our contracts. If rating agencies downgrade our credit ratings, our borrowing costs would likely increase, our potential pool of investors and funding resources could be reduced, and we could be required to post additional collateral under select contracts. These events would likely reduce our liquidity and profitability and could have a material adverse effect on our results of operations, financial condition and cash flows.
We rely on access to the financial markets. General economic conditions and disruptions in the financial markets could adversely affect our ability to raise capital on favorable terms, or at all, and cause increases in our interest expense.
From time to time we rely on access to the capital and credit markets as a source of liquidity for capital requirements not satisfied by operating cash flows. These capital and credit markets experience volatility and disruption from time to time and the ability of corporations to raise capital can be negatively affected. Disruptions in
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
the capital and credit markets make it harder and more expensive to raise capital. Our ability to raise capital on favorable terms, or at all, can be adversely affected by unfavorable market conditions or declines in our creditworthiness, and we may be unable to access adequate funding to refinance our debt as it becomes due or finance capital expenditures. The extent of any impact will depend on several factors, including our operating cash flows, financial condition and prospects, the overall supply and demand in the credit markets, our credit ratings, credit capacity, the cost of financing, the financial condition, performance and prospects of other companies in our industry or with similar financial circumstances and other general economic and business conditions. It may also depend on the performance of credit counterparties and financial institutions with which we do business. Access to funds under our existing financing arrangements is also dependent on the ability of our counterparties to meet their financing commitments and our satisfying conditions to borrowing. Our inability to obtain financing on reasonable terms, or at all, with creditworthy counterparties could adversely affect our results of operations, financial condition and cash flows. If our available funding is limited or we are forced to fund our operations at a higher cost, these conditions may require us to curtail our business activities and increase our cost of funding, both of which would adversely impact our profitability. See Note 6. Debt of DPL's Consolidated Financial Statements and Note 5. Debt of AES Ohio's Financial Statements included in Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K for information regarding indebtedness. See also Item 7A. - Quantitative and Qualitative Disclosures about Market Risk for information related to market risks.
DPL is a holding company and parent of AES Ohio and other subsidiaries. DPL’s cash flow is dependent on the cash flows of AES Ohio and its other subsidiaries and their ability to pay cash to DPL.
DPL is a holding company with no material assets other than the ownership of its subsidiaries, and accordingly all cash is generated by the activities of its subsidiaries, principally AES Ohio. As such, DPL’s cash flow is largely dependent on the cash flows of AES Ohio and its ability to pay cash to DPL. There are a number of rate proceedings pending or anticipated that we cannot predict the outcome of, which could adversely affect DPL and AES Ohio. See Note 2. Regulatory Matters of DPL's Consolidated Financial Statements and AES Ohio's Financial Statements included in Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K for descriptions of AES Ohio's ESP and other regulatory proceedings. In addition, AES Ohio is regulated by the PUCO, which possesses broad oversight powers to ensure that the needs of utility customers are being met. The PUCO could impose additional restrictions on the ability of AES Ohio to distribute, loan or advance cash to DPL pursuant to these broad powers. A significant limitation on AES Ohio’s ability to pay distributions or loan or advance funds to DPL could have a material adverse effect on DPL’s results of operations, financial condition and cash flows.
Our ownership by AES subjects us to potential risks that are beyond our control.
All of AES Ohio’s common stock is owned by DPL, and DPL is an indirectly wholly owned subsidiary of AES. Due to our relationship with AES, any adverse developments and announcements concerning AES may impair our ability to access the capital markets and to otherwise conduct business. In particular, downgrades in AES’s credit ratings could result in DPL’s or AES Ohio’s credit ratings being downgraded.

ITEM 3. 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 in light of 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. For more information, see Note 2. Regulatory Matters and Note 10. Contractual Obligations, Commercial Commitments and Contingencies to DPL's Consolidated Financial Statements and Note 2.

As of March 4, 2025, all of the outstanding common stock of DPL is owned indirectly by AES and directly by a wholly-owned subsidiary of AES. AES Ohio’s common stock is held solely by DPL. As a result, DPL and AES Ohio stock is not listed for trading on any stock exchange.
Distributions
AES Ohio declares and pays distributions on its common shares to its parent DPL from time to time as declared by the AES Ohio Board of Directors. During the years ended December 31, 2024, 2023 and 2022, AES Ohio declared and paid distributions totaling $40.0 million, $83.0 million and $64.0 million, respectively.
DPL’s Amended Articles of Incorporation contain restrictions on DPL’s ability to make dividends, distributions and affiliate loans (other than to its subsidiaries), including restrictions on making such dividends, distributions and loans if certain financial ratios exceed specified levels and DPL’s senior long-term debt rating from a rating agency is below investment grade. As of December 31, 2024, DPL did not meet these requirements and was prohibited under its Articles of Incorporation from making a distribution to its shareholder or making a loan to any of its affiliates (other than its subsidiaries).

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis should be read in conjunction with DPL’s audited Consolidated Financial Statements and the related Notes thereto and AES Ohio’s audited Financial Statements and the related Notes thereto included in Item 8. Financial Statements and Supplementary Data of this Form 10-K. The following discussion contains forward-looking statements. Our actual results may differ materially from the results suggested by these forward-looking statements. See “Forward-Looking Statements” at the beginning of this Form 10-K and Item 1A. Risk Factors. For a list of certain terms, abbreviations or acronyms in this discussion, see Glossary of Terms at the beginning of this Form 10-K.
OVERVIEW OF 2024 RESULTS AND STRATEGIC PERFORMANCE
The most important matters on which we focus in evaluating our financial condition and operating performance and allocating our resources include: (i) recurring factors which have significant impacts on operating performance such as: regulatory action, environmental matters, weather and weather-related damage in our service area, customer growth, and the local economy; (ii) our progress on performance improvement and growth strategies designed to maintain high standards in several operating areas (including safety, reliability, customer satisfaction, operations, financial and enterprise-wide performance, talent management/people, capital allocation/sustainability and corporate social responsibility) simultaneously; and (iii) our short-term and long-term financial and operating strategies. For a discussion of how we are impacted by regulation and environmental matters, please see Note 2. Regulatory Matters of DPL's Consolidated Financial Statements and AES Ohio's Financial Statements included in Item 8. Financial Statements and Supplementary Data and Item 1. Business - Environmental Matters of this Annual Report on Form 10-K.
Operational Excellence
Our objective is to optimize AES Ohio’s performance in the U.S. utility industry by focusing on the following areas: safety, operations (reliability and customer satisfaction), financial and enterprise-wide performance (efficiency and cost savings, talent management/people, capital allocation/sustainability and corporate social responsibility). We set and measure these objectives carefully, balancing them in a way and to a degree necessary to ensure a sustainable high level of performance in these areas simultaneously compared to our peers. We monitor our performance in these areas, and where practical and meaningful, compare performance in some areas to peer utilities. Because
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
some of our financial and enterprise-wide performance measures are company-specific performance goals, they are not benchmarked.
Our safety performance is measured by both leading and lagging metrics. Our leading safety metrics track safety observations, safety meeting engagement and the reporting of near miss events which provide learning opportunities to strengthen our safety practices and process. Our lagging safety metrics track lost workday cases and OSHA total recordable incidents. We are committed to excellence in safety and have implemented various programs to increase safety awareness and improve work practices.
AES Ohio measures delivery reliability by Customer Average Interruption Duration Index ("CAIDI"), System Average Interruption Duration Index ("SAIDI") and System Average Interruption Frequency Index ("SAIFI") and benchmarks the reliability metrics against other utilities at both the state and national levels. AES Ohio also measures customer centricity on more of an individual basis by the industry metric of Customers Experiencing Multiple Interruptions of five or more times (“CEMI-5”). We measure customer perceptions of their overall experience using the Qualtrics XM platform. Areas measured include overall Customer Satisfaction as well as customer perceptions of affordability, reliability and customer service. We also subscribe to the J.D. Power Electric Utility Residential Customer Satisfaction Study.

DPL - Revenue
Retail customers, especially residential and commercial customers, consume more electricity on warmer and colder days. Therefore, our retail sales demand is affected by the number of heating and cooling degree-days occurring during a year. Cooling degree-days typically have a more significant effect than heating degree-days since some residential customers do not use electricity to heat their homes. Additionally, our retail revenue is affected by
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
regulated rates and riders, including the changes to our ESP, described in Note 2. Regulatory Matters of DPL's Consolidated Financial Statements.

(a)Heating and cooling degree-days are a measure of the relative heating or cooling required for a home or business. The heating degrees in a day are calculated as the degrees that the average actual daily temperature is below 65 degrees Fahrenheit. For example, if the average temperature on March 20th was 40 degrees Fahrenheit, the heating degrees for that day would be the 25-degree difference between 65 degrees and 40 degrees. Similarly, cooling degrees in a day are calculated as the degrees that the average actual daily temperature is above 65 degrees Fahrenheit.
(b)30-year average is computed from observed degree-days in the Dayton area on a trailing 30-year basis.

During the year ended December 31, 2024, Depreciation and amortization increased $13.1 million compared to the prior year,primarily due to additional assets placed in service.
DPL - Taxes Other Than Income Taxes
During the year ended December 31, 2024, Taxes other than income taxes increased $12.7 million compared to the prior year, primarily due to higher property taxes due to higher assessed values compared to the prior year driven by AES Ohio's capital expenditure program.
DPL - Interest Expense, Net
During the year ended December 31, 2024, Interest expense, net increased $21.4 million compared to the prior year, primarily due to new debt issuances at AES Ohio and the prior year one-time deferral of carrying costs associated with the approval of ESP 4, partially offset by an increase in AFUDC debt.
DPL - Other Income, Net
During the year ended December 31, 2024, Other income, net decreased $2.1 million compared to the prior year, driven primarily by higher defined benefit plan costs, partially offset by higher AFUDC equity.
DPL - Income Tax Expense / (Benefit)
Income tax benefit was $3.0 million for the year ended December 31, 2024 compared to income tax expense of $6.6 million for the year ended December 31, 2023. The decrease in income tax expense compared to the prior year was primarily due to lower pre-tax income and an increase in the net tax benefit related to the reversal of excess deferred taxes of AES Ohio.
RESULTS OF OPERATIONS BY SEGMENT - DPL
DPL manages its business through one reportable operating segment, the Utility 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 DPL and are the most relevant measures considered in DPL’s internal evaluation of the financial performance of its segment. The Utility segment is comprised of AES Ohio, a public electric transmission and distribution utility, with all other nonutility business activities aggregated separately. See Note 1. Overview and Summary of Significant Accounting Policies of DPL's Consolidated Financial Statements for further information on AES Ohio. The “Other” nonutility category primarily includes interest expense, cash and other immaterial balances. The accounting policies of the identified segment are consistent with those policies and procedures described in the summary of significant accounting policies.
See Note 12. Business Segments of DPL's Consolidated Financial Statements for additional information regarding DPL’s reportable segment.

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

AES Ohio - Taxes Other Than Income Taxes
During the year ended December 31, 2024, Taxes other than income taxes increased $12.8 millionprimarily due to higher property taxes due to higher assessed values compared to the prior year driven by AES Ohio's capital expenditure program.
AES Ohio - Interest Expense, Net
During the year ended December 31, 2024, Interest expense, net increased $22.4 million primarily due to new debt issuances at AES Ohio and the prior year one-time deferral of carrying costs associated with the approval of ESP 4, partially offset by an increase in AFUDC debt.

AES Ohio - Income Tax Expense / (Benefit)
During the year ended December 31, 2024, Income tax expense decreased $10.3 million compared to the prior year, primarily due to lower pre-tax income and an increase in the net tax benefit related to the reversal of excess deferred taxes of AES Ohio.
KEY TRENDS AND UNCERTAINTIES
During 2024 and beyond, we expect that our financial results will be driven primarily by retail demand and weather. In addition, DPL's and AES Ohio's financial results are likely to be driven by other factors including, but not limited to:
•regulatory outcomes and impacts;
•the passage of new legislation, implementation of regulations or other changes in regulations; and
•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 report impact us more significantly than we currently anticipate, then these factors, or other factors unknown to us, may impact our operating margin, 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 of this Annual Report on Form 10-K.
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
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 December 31, 2024. We currently anticipate reinstituting the customer disconnections process and collection efforts and write-off processes before the end of the third quarter of 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 II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Capital Resources and Liquidity of this Form 10-K.
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.
U.S. Income Tax - The macroeconomic and political environments in the U.S. have changed in recent years. This could result in significant impacts to future tax law. In the U.S., the IRA includes a 15% corporate alternative minimum tax (CAMT) based on adjusted financial statement income. In September 2024, the IRS released proposed regulations on the 15% CAMT. We are currently evaluating the potential impacts of these regulations.
Inflation - In the markets in which we operate, there have been higher rates of inflation recently. If inflation increases in our markets, it may increase our expenses that we may not be able to pass through to customers. AES Ohio may have the ability to recover operations and maintenance costs through the regulatory process; however, timing impacts on recovery may vary. In addition, the standard service offer auction process has reflected current macroeconomic conditions in terms of pricing.
Interest Rates - In the U.S. there has been a rise in interest rates since 2021, and interest rates are expected to remain volatile in the near term. Although all of our existing DPL and AES Ohio long-term debt is at fixed rates, an increase in interest rates can have several impacts on our business. For our existing short-term debt under floating rate structures and any future debt refinancings or future new money financings, rising interest rates will increase future financing costs. Our floating rate debt is currently limited to short-term borrowings under the AES Ohio Credit Agreement and $150 million Term Loan Agreement. DPL manages a hedging program to help reduce uncertainty and exposure to future interest rates.
Regulatory
For a comprehensive discussion of the market structure and regulation of DPL and AES Ohio, see Item 1. - Business - Regulation And Market Structure.
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 have been scheduled for April 2025.
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
Smart Grid Phase 2 Plan - In February 2024, AES Ohio filed a Smart Grid Phase 2 with the PUCO proposing a ten-year investment plan to begin after Smart Grid Phase 1 ends. On September 13, 2024, AES Ohio reached a settlement with the PUCO staff and other parties on the pending Smart Grid Phase 2 application. The settlement provides for a four-year plan to invest $240.5 million of capital and $18.6 million of operations and maintenance expenses related to grid modernization, support of Distributed Energy Resources, Economic Development and an enhanced Telecommunications network. These costs will be recovered through the existing Infrastructure Investment Rider. If approved, AES Ohio will implement a comprehensive grid modernization project that will deliver benefits to customers, society as a whole and to AES Ohio. An evidentiary hearing was held on October 29, 2024, and we expect an order from the PUCO by the second quarter of 2025, prior to the end of Smart Grid Phase 1.
2024 Distribution Rate Case application - On November 29, 2024, AES Ohio filed a new 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:
•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;
•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
•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. AES Ohio proposed an evidentiary hearing be held beginning June 2, 2025; however, the PUCO has not yet established a procedural schedule for the proceeding.
For more information on the above matters, see Note 2. Regulatory Matters of DPL's Consolidated Financial Statements and AES Ohio's Financial Statements.
CAPITAL RESOURCES AND LIQUIDITY
OVERVIEW
DPL and AES Ohio had unrestricted cash and cash equivalents of $54.0 million and $24.6 million, respectively, as of December 31, 2024. At that date, neither DPL nor AES Ohio had short-term investments. Available borrowing capacity at AES Ohio was $110.0 million at December 31, 2024. DPL and AES Ohio had aggregate principal amounts of long-term debt outstanding of $1,852.2 million and $1,021.6 million, respectively, at December 31, 2024.
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 or otherwise could have material adverse effects on our results of operations, financial condition and cash flows. In addition, changes in the timing of tariff increases or delays in the regulatory determinations could affect the cash flows and results of operations of our businesses. See "RISKS ASSOCIATED WITH GOVERNMENTAL REGULATION AND LAWS" and "RISKS RELATED TO OUR INDEBTEDNESS AND FINANCIAL CONDITION" in Item 1A. - Risk Factors and Item 1. - Business - Regulation And Market Structure.
AES Ohio must first seek approval from the PUCO to issue new stocks, bonds, notes and other evidences of indebtedness. Annually, AES Ohio must receive authority to issue and assume liability on short-term debt, not to exceed 12 months. AES Ohio received an order from the PUCO on December 4, 2024 granting authority through December 31, 2025 to, among other things, issue up to $450.0 million in aggregate principal amount of short-term indebtedness. AES Ohio must also receive authority to issue and assume liability on long-term debt, in excess of 12 months. AES Ohio last received approval in 2023 to, among other things, issue up to $300 million in First Mortgage
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
Bonds. AES Ohio also has restrictions on the amount of new debt that may be issued due to contractual obligations of AES and by financial covenant restrictions under existing debt obligations. AES Ohio does not believe such restrictions will be a limiting factor in our ability to issue debt in the ordinary course of prudent business operations.
CASH FLOWS
DPL’s financial condition, liquidity and capital requirements include the consolidated results of its principal subsidiary AES Ohio. All material intercompany accounts and transactions have been eliminated in consolidation.

LIQUIDITY
We expect our existing cash balances, cash generated from operating activities and borrowing capacity on our existing credit facilities will be adequate to meet our anticipated operating needs, including interest expense on our debt and any distributions 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 equity capital contributions as our internal liquidity needs and market conditions warrant. We also expect that the borrowing capacity under the AES Ohio Credit Agreement will continue to be available to manage working capital requirements during those periods. The absence of adequate liquidity could adversely affect our ability to operate our business and have a material adverse effect on our results of operations, financial condition and cash flows.

Credit Ratings
Our ability to borrow money or to refinance existing indebtedness and the interest rates at which we can borrow money or refinance existing indebtedness are affected by our credit ratings. In addition, the applicable interest rate on AES Ohio’s Credit Agreement (as well as the amount of certain other fees in the agreements) are dependent upon the credit ratings of AES Ohio. Downgrades in the credit ratings of AES could result in DPL's or AES Ohio’s credit ratings being downgraded. Any reduction in our debt or credit ratings may adversely affect the trading price of our outstanding debt securities. Non-investment grade companies may experience higher costs to issue new securities.

Such ratings may be subject to revision or withdrawal at any time by the assigning rating organization, and each rating should be evaluated independently of any other rating. If the rating agencies were to reduce our debt or credit ratings, our borrowing costs may increase, our potential pool of investors and funding resources may be reduced, and we may be required to post additional collateral under selected contracts. These events could have an adverse effect on our results of operations, financial condition and cash flows. In addition, any such reduction in our debt or credit ratings may adversely affect the trading price of our outstanding debt securities.
Off-Balance Sheet Arrangements
AES Ohio owns a 4.9% equity ownership interest in OVEC which is recorded using the cost method of accounting under GAAP. At December 31, 2024, AES Ohio could be responsible for the repayment of 4.9%, or $48.8 million, of a $996.6 million debt obligation comprised of both fixed and variable rate securities with maturities between 2026 and 2040. This would only happen if OVEC defaulted on its debt payments. At December 31, 2024, we have no knowledge of such a default.
Contractual Obligations
We enter into various contractual obligations that may affect the liquidity of our operations. At December 31, 2024, these include:

DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
Purchased power commitments
AES Ohio enters into long-term contracts for purchased power through the SSO competitive bid auctions. In general, these contracts are subject to variable quantities and are terminable only in limited circumstances.
Purchase orders and other contractual obligations
At December 31, 2024, DPL and AES Ohio had various other contractual obligations including contracts to purchase goods and services with various terms and expiration dates. Due to uncertainty regarding the timing and payment of future obligations to the Service Company, and DPL's and AES Ohio's ability to terminate such obligations upon 90 days' notice, we have excluded such amounts in the contractual obligations table above. This table also does not include:
•regulatory liabilities (see Note 2. Regulatory Matters of DPL's Consolidated Financial Statements and AES Ohio's Financial Statements.);
•taxes (see Note 7. Income Taxes of DPL's Consolidated Financial Statements and Note 6. Income Taxes of AES Ohio's Financial Statements);
•pension and other postretirement employee benefit liabilities (see Note 8. Benefit Plans of DPL's Consolidated Financial Statements and Note 7. Benefit Plans of AES Ohio's Financial Statements);
•contingencies (see Note 10. Contractual Obligations, Commercial Commitments and Contingencies of DPL's Consolidated Financial Statements and Note 9. Contractual Obligations, Commercial Commitments and Contingencies of AES Ohio's Financial Statements); and
•amounts due to related parties (see Note 11. Related Party Transactions of DPL's Consolidated Financial Statements and Note 10. Related Party Transactions of AES Ohio's Financial Statements).
Reserve for uncertain tax positions
Due to the uncertainty regarding the timing of future cash outflows associated with our unrecognized tax benefits of $0.4 million at December 31, 2024, we are unable to make a reliable estimate of the periods of cash settlement with the respective tax authorities and have not included such amounts in the contractual obligations table above.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
DPL’s Consolidated Financial Statements and AES Ohio’s Financial Statements are prepared in accordance with GAAP. In connection with the preparation of these financial statements, our management is required to make assumptions, estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and the related disclosure of contingent liabilities. These assumptions, estimates and judgments are based on our historical experience and assumptions that we believe to be reasonable at the time. However, because future events and their effects cannot be determined with certainty, the determination of estimates requires the exercise of judgment. Our critical accounting estimates are those which require assumptions to be made about matters that are highly uncertain. Our significant accounting policies are described in Note 1. Overview and Summary of Significant Accounting Policies of DPL's Consolidated Financial Statements and AES Ohio's Financial Statements.
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 allowances for deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits.
Revenue Recognition
At the end of each month, amounts of energy delivered to customers since the date of the last meter reading are estimated and the corresponding unbilled revenue is accrued. In making our estimates of unbilled revenue, we use complex models that consider various factors including known amounts of energy usage by nearly all residential, small commercial and industrial customers; estimated line losses; and estimated customer rates based on prior period billings. Given the use of these models, and that customers are billed on a monthly cycle, we believe it is unlikely that materially different results will occur in future periods when revenue is billed. The effect on 2024 revenue and ending unbilled revenue of a one percentage point change in unbilled MWhs for the month of December 2024 is immaterial. For further information regarding the nature of our revenue streams and our critical accounting policies affecting revenue recognition, see Note 1. Overview and Summary of Significant Accounting

Policies and Note 13. Revenue of DPL's Consolidated Financial Statements and Note 1. Overview and Summary of Significant Accounting Policies and Note 11. Business Segments of AES Ohio's Financial Statements.
Credit Losses
We use a forward-looking "expected loss" model to recognize allowances for credit losses on customer and other receivables. 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 the collectability, as applicable, of our receivables balance. Our determination of the allowance for credit losses requires us to make estimates and judgments regarding our customers' ability to pay amounts due, which have required a higher degree of estimation given the 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. We believe such estimates and judgments are reasonable and the related allowance for credit losses is adequate as of December 31, 2024; however, changes in such estimates and judgments could result in a different conclusion, which could be material. The effect of a one percentage point change in the assumptions used in the allowance for credit losses estimate as of December 31, 2024 is approximately $0.9 million. See Note 1. Overview and Summary of Significant Accounting Policies - Accounts Receivable and Allowance for Credit Losses of DPL's Consolidated Financial Statements and AES Ohio's Financial Statements in this Annual Report on Form 10-K for further information on our receivable balances.
Income Taxes
We are subject to federal and state income taxes. Our income tax provision requires significant judgment and is based on calculations and assumptions that are subject to examination by the U.S. Internal Revenue Service and other tax authorities. We regularly assess the potential outcome of tax examinations when determining the adequacy of our income tax provisions by considering the technical merits of the filing position, case law and results of previous tax examinations. Accounting guidance for uncertainty in income taxes prescribes a more-likely-than-not recognition threshold and measurement requirements for financial statement reporting of our income tax positions. Tax reserves have been established which we believe to be adequate in relation to the potential for additional assessments. Once established, reserves are adjusted only when there is more information available or when an event occurs necessitating a change to the reserves. While we believe that the amount of the tax reserves is reasonable, it is possible that the ultimate outcome of current or future examinations may be materially different than the reserve amounts.
Regulatory Assets and Liabilities
Application of the provisions of GAAP relating to regulatory accounting requires us to reflect the effect of rate regulation in DPL’s Consolidated Financial Statements and AES Ohio’s Financial Statements. For regulated businesses subject to federal or state cost-of-service rate regulation, regulatory practices that assign costs to accounting periods may differ from accounting methods generally applied by non-regulated companies. When it is probable that regulators will permit the recovery of current costs through future rates charged to customers, we defer these costs as Regulatory assets that otherwise would be expensed by non-regulated companies. Likewise, we recognize Regulatory liabilities when it is probable that regulators will require customer refunds through future rates and when revenue is collected from customers for expenses that are not yet incurred. Regulatory assets are amortized into expense and Regulatory liabilities are amortized into income over the recovery period authorized by the regulator.
We evaluate our Regulatory assets to determine whether or not they are probable of recovery through future rates and make various assumptions in our analyses. The expectations of future recovery are generally based on orders issued by regulatory commissions or historical experience, as well as discussions with applicable regulatory authorities. If recovery of a regulatory asset is determined to be less than probable, it will be expensed in the period the assessment is made. We currently believe the recovery of our Regulatory assets is probable. See Note 2. Regulatory Matters of DPL's Consolidated Financial Statements and AES Ohio's Financial Statements.
DPL Inc. and AES Ohio
Form 10-K for the Annual Period ended December 31, 2024
Pension Plans
The valuation of our benefit obligation, fair value of plan assets, and net periodic benefit costs requires various estimates and assumptions, the most significant of which include the discount rate and expected return on plan assets. We review these and other assumptions, such as mortality, on an annual basis. See Note 1. Overview and Summary of Significant Accounting Policies of DPL's Consolidated Financial Statements and AES Ohio's Financial Statements for information on our accounting policies regarding the Pension Plans.
Contingent and Other Obligations
During the conduct of our business, we are subject to a number of federal and state laws and regulations, as well as other factors and conditions that potentially subject us to environmental, litigation, insurance and other risks. We periodically evaluate our exposure to such risks and record estimated liabilities for those matters where a loss is considered probable and reasonably estimable in accordance with GAAP. In recording such estimated liabilities, we may make assumptions, estimates and judgments that affect the reported amounts of assets, liabilities and expenses as they relate to contingent and other obligations. These assumptions and estimates are based on historical experience and assumptions and may be subject to change. We believe such estimates and assumptions are reasonable.
New Accounting Standards
See Note 1. Overview and Summary of Significant Accounting Policies of DPL's Consolidated Financial Statements and AES Ohio's Financial Statements for a discussion of new accounting pronouncements and the potential impact to our results of operations, financial condition and cash flows.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Overview
We are subject to certain market risks including, but not limited to, changes in commodity prices for electricity and fluctuations in interest rates. We use various market risk-sensitive instruments, including derivative contracts, primarily to limit our exposure to fluctuations in interest rates. Our U.S. Risk Management Committee (U.S. RMC), comprised of members of senior management, is responsible for establishing risk management policies and the monitoring and reporting of risk exposures related to our operations. The U.S. RMC meets on a regular basis with the objective of identifying, assessing and quantifying material risk issues and developing strategies to manage these risks.
The disclosures presented in this section are based upon a number of assumptions; actual effects may differ. The safe harbor provided in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 shall apply to the disclosures contained in this section. For further information regarding market risk, see Item 1A. - Risk Factors. Our businesses may incur substantial costs and liabilities and be exposed to price volatility as a result of risks associated with the electricity markets, which could have a material adverse effect on our financial performance.
Purchased power
AES Ohio conducts competitive bid auctions to purchase power for SSO service, as all of AES Ohio's SSO is sourced through the competitive bid auction.
As a result of DPL's exit from the majority of its coal-fired generation, changes in the prices of fuel and purchased power are not expected to have a material impact on our results of operations, financial position or cash flows. Further, AES Ohio's exposure to fluctuations in the price of power is limited because we recover our power purchased from the competitive bid auction through the Standard Offer Rate tariff.
Interest rate risk
We use long-term debt as a significant source of capital in our business, which exposes us to interest rate risk. We do not enter into market risk sensitive instruments for trading purposes. We manage our exposure to interest rate risk through the use of fixed-rate debt and by refinancing existing long-term debt at times when it is deemed economic and prudent. In addition, AES Ohio's Credit Agreement and $150 million Term Loan Agreement bear interest at a variable rate based on either the Prime interest rate or the SOFR. Fair values relating to financial instruments are dependent upon prevailing market rates of interest. In regard to our fixed rate debt, the interest rate risk with respect to long-term debt primarily relates to the potential impact a change in interest rates has on the fair value of our fixed-rate debt and not on our financial condition or results of operations. Our interest rate risk on our fixed-rate debt is associated with refinancing activity. Market indexes can be affected by market demand, supply, market interest rates and other economic conditions. See Note 6. Debt of DPL's Consolidated Financial Statements and Note 5. Debt of AES Ohio's Financial Statements.
At December 31, 2024, DPL's and AES Ohio's variable rate debt totaled $290.0 million, consisting of $140.0 million under AES Ohio's revolving credit facility and the $150 million Term Loan Agreement. At December 31, 2024, a 100-basis point change in the applicable rates on our variable-rate debt would result in an approximate $2.9 million change in DPL's interest expense and an approximate $2.9 million change in AES Ohio's interest expense.
The principal amount of DPL’s long-term debt was $1,852.2 million at December 31, 2024, consisting of DPL’s unsecured notes, Capital Trust II securities along with AES Ohio’s First Mortgage Bonds and the WPAFB note. All of DPL’s existing debt was adjusted to fair value at the Merger date according to ASC 805 - Business Combinations. The fair value of this debt at December 31, 2024 was $1,709.0 million, based on current market prices or

Equity price risk
At December 31, 2024, approximately 31% of the defined benefit pension plan assets were comprised of investments in equity securities and 69% related to investments in fixed income securities and cash and cash equivalents. The equity securities are carried at their market value of approximately $81.3 million at December 31, 2024. A hypothetical 10% decrease in prices quoted by stock exchanges would result in an $8.1 million reduction in fair value at December 31, 2024 and approximately a $1.1 million increase to the 2025 pension expense. See Note 8. Benefit Plans of DPL's Consolidated Financial Statements and Note 7. Benefit Plans of AES Ohio's Financial Statements for more information on our pension plans.
Credit risk
Credit risk is the risk of an obligor's failure to meet the terms of any investment contract, loan agreement or otherwise perform as agreed. Credit risk arises from all activities in which success depends on issuer, borrower or counterparty performance, whether reflected on or off the balance sheet. We limit our credit risk by assessing the creditworthiness of potential counterparties before entering into transactions with them and continue to evaluate their creditworthiness after transactions have been originated. We use the three leading corporate credit rating agencies and other current market-based qualitative and quantitative data to assess the financial strength of counterparties on an ongoing basis. We may require various forms of credit assurance from counterparties to mitigate credit risk.

Report of Independent Registered Public Accounting Firm
To the Shareholder and the Board of Directors of DPL Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of DPL Inc. and subsidiaries (the Company) as of December 31, 2024 and 2023, the related consolidated statements of operations, consolidated statements of comprehensive income / (loss), consolidated statements of shareholder's equity / (deficit), and the consolidated statements of cash flows for each of the three years in the period ended December 31, 2024, and the related notes and financial statement schedules listed in the Index at Item 15 (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with U.S. generally accepted accounting principles.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting in accordance with the standards of the PCAOB. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the Board of Directors and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
Regulatory Accounting
Description of the Matter As described in Note 1 to the consolidated financial statements, the Company applies the provisions of FASB Accounting Standards Codification 980 “Regulated Operations”, which gives recognition to the ratemaking and accounting practices of the Public Utilities Commission of Ohio and the Federal Energy Regulatory Commission.
Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory liabilities generally represent obligations to provide refunds or future rate reductions to customers for previous overcollections or the deferral of revenues collected for costs that the Company expects to incur in the future. Accounting for the economics of rate regulation affects multiple consolidated financial statement line items, including property, plant, and equipment; regulatory assets and liabilities; revenues; and depreciation expense, and related disclosures in the Company’s consolidated financial statements.
Auditing the Company’s regulatory accounting was complex due to the significant knowledge and experience required to assess the impact of regulatory orders on the consolidated financial statements including understanding the nature of the rate orders issued, or expected to be issued, and to assess the relevance and reliability of audit evidence to support the impacted account balances and disclosures.
How We Addressed the Matter in Our Audit Our audit procedures related to regulatory assets and liabilities included testing the effectiveness of management’s controls, such as the Company’s evaluation of regulatory orders and other developments that may affect the calculation of recorded amounts, the likelihood of recovering regulatory assets and the sufficiency of regulatory liabilities. Our procedures also included testing management’s calculations of recorded amounts, obtaining, reading, and evaluating relevant regulatory orders issued by the PUCO to DPL Inc., and considering regulatory precedents established by the PUCO, to evaluate the likelihood of recovering regulatory assets, the sufficiency of regulatory liabilities and the accuracy and completeness of required disclosures related to the impacts of rate regulation and regulatory developments.

Notes to Consolidated Financial Statements
For the years ended December 31, 2024, 2023 and 2022
1. OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
DPL, an indirectly wholly-owned subsidiary of AES, is a diversified regional energy 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 consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, transmission and distribution services are still regulated. AES Ohio has the exclusive right to provide such service to its approximately 537,000 customers located in West Central Ohio. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. AES Ohio also provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. AES Ohio sources all of the generation for its SSO customers through a competitive bid process. AES Ohio's sales reflect the general economic conditions, seasonal weather patterns of the area, the market price of electricity and customer energy efficiency initiatives. AES Ohio owns numerous transmission facilities. AES Ohio records revenue and expenses for its proportional share of energy and capacity from its investment in OVEC.
DPL’s other primary subsidiaries are MVIC and Miami Valley Lighting. MVIC is our captive insurance company that provides insurance services to AES Ohio and our other subsidiaries, and Miami Valley Lighting provides street and outdoor lighting services to customers in the Dayton region. DPL's subsidiaries are all wholly-owned. DPL also has a wholly-owned business trust, DPL Capital Trust II, formed for the purpose of issuing trust capital securities to investors.
AES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, AES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses and records regulatory assets when incurred costs are expected to be recovered in future customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs or overcollections of riders.
Agreement to Sell Minority Interest in AES Ohio
On September 13, 2024, DPL entered into (i) a Purchase and Sale Agreement with Astrid Holdings LP ("Investor"), a wholly-owned subsidiary of Caisse de dépôt et placement du Québec ("CDPQ"), pursuant to which DPL agreed to sell to Investor 15% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Holdings, Inc. ("Ohio Holdings" and, such agreement, the "Ohio Holdings Purchase Agreement") for a purchase price of approximately $273 million, subject to adjustment, and (ii) a Purchase and Sale Agreement with Investor, pursuant to which DPL agreed to sell to Investor 17.65% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Investments, Inc. ("Ohio Investments" and, such agreement, the "Ohio Investments Purchase Agreement" and together with the Ohio Holdings Purchase Agreement, the "Purchase Agreements") for a purchase price of approximately $273 million, subject to adjustment. Upon consummation of the transactions contemplated by the Ohio Holdings Purchase Agreement and the Ohio Investments Purchase Agreement together, the ("Closings"), CDPQ will own an aggregate indirect equity interest in AES Ohio of approximately 30%, with total proceeds to DPL of approximately $546 million, subject to adjustment.
It is anticipated that the Closings will occur on the same day in the first half of 2025. There will be no change in management or operational control of DPL, Ohio Investments, Ohio Holdings or AES Ohio as a result of these transactions.
The purchases and sales of the shares of capital stock of each of Ohio Holdings and Ohio Investments contemplated under each of the Purchase Agreements are subject to the satisfaction of certain customary conditions described in the Purchase Agreements, including, among others, receipt of the approval of the PUCO, the FERC and completion of review by the Committee on Foreign Investments in the United States ("CFIUS"). As of
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
the filing of this report, approval has been received from the FERC and CFIUS has completed its review. In addition, each of the parties to the Purchase Agreements has agreed to customary covenants therein.
In connection with the Closings, Investor, Ohio Investments and DPL will enter into a Shareholders' Agreement with respect to Ohio Investments (the "Shareholders' Agreement"), the form of which has been agreed to by the parties. The Shareholders' Agreement will establish the general framework governing the relationship between and among Investor and the Company, and their respective successors and transferees, as shareholders of Ohio Investments. In addition, Investor, Ohio Holdings and Ohio Investments will also enter into a Shareholders' Agreement with respect to Ohio Holdings with substantially identical terms.
Financial Statement Presentation
DPL’s Consolidated Financial Statements include the accounts of DPL and its wholly-owned subsidiaries, except for DPL Capital Trust II, which is not consolidated consistent with the provisions of GAAP. All material intercompany accounts and transactions are eliminated in consolidation. We have evaluated subsequent events through the date this report was issued.
Reclassifications
Certain amounts from prior periods have been reclassified to conform to the current period presentation.
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 receivables and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits.
Cash and Cash Equivalents
Cash and cash equivalents are stated at cost, which approximates fair value. All highly liquid short-term investments with original maturities of three months or less are considered cash equivalents.
Restricted Cash
Restricted cash includes cash which is restricted as to withdrawal or usage. The nature of the restrictions includes restrictions imposed by agreements related to deposits held as collateral.
The following table summarizes cash, cash equivalents and restricted cash amounts reported within the Consolidated Balance Sheets that reconcile to the total of such amounts as shown on the Consolidated Statements of Cash Flows:

Cash and cash equivalents $ 54.0 $ 41.0

Allowance for credit losses (6.1) (0.9)
Total accounts receivable, net $ 106.8 $ 92.5
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
The following table is a rollforward of our allowance for credit losses related to the accounts receivable balances for the years ended December 31, 2024 and 2023:
For the years ended December 31,
$ in millions 2024 2023
Allowance for credit losses:
Beginning balance $ 0.9 $ 0.5
Current period provision 8.3 5.4
Write-offs charged against allowance (3.7) (6.0)
Recoveries collected 0.6 1.0
Ending balance $ 6.1 $ 0.9
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 written off when reasonable collections efforts have been exhausted. During 2024, the current period provision and allowance for credit losses 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. We currently anticipate reinstituting the customer disconnections process and collection efforts and write-off processes by the end of the third quarter of 2025.
Inventories
Inventories are carried at average cost, net of reserves, and consist of materials and supplies used for utility operations.
Regulatory Accounting
As a regulated utility, AES Ohio applies the provisions of ASC 980 - Regulated Operations, which gives recognition to the ratemaking and accounting practices of the PUCO and the FERC. Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory assets have been included as allowable costs for ratemaking purposes, as authorized by the PUCO or established regulatory practices. Regulatory liabilities generally represent obligations to make refunds or future rate reductions to customers for previous over collections or the deferral of revenue collected for costs that AES Ohio expects to incur in the future.
The deferral of costs (as regulatory assets) is appropriate only when the future recovery of such costs is probable. In assessing probability, we consider such factors as specific orders from the PUCO or the FERC, regulatory precedent and the current regulatory environment. To the extent recovery of costs is no longer deemed probable, related regulatory assets would be required to be expensed in current period earnings. Our regulatory assets and liabilities have been created pursuant to a specific order of the PUCO or the FERC or established regulatory practices, such as other utilities under the jurisdiction of the PUCO or the FERC being granted recovery of similar costs. It is probable, but not certain, that these regulatory assets will be recoverable, subject to approval by the PUCO or the FERC. Regulatory assets and liabilities are classified as current or non-current based on the term in which recovery is expected. See Note 2. Regulatory Matters for more information.
Property, Plant and Equipment
New property, plant and equipment additions are stated at cost. For regulated transmission and distribution property, cost includes direct labor and material, allocable overhead expenses and AFUDC. AFUDC represents the cost of borrowed funds and equity used to finance regulated construction projects. Capitalization of AFUDC and interest ceases at either project completion or at the date specified by regulators.
For substantially all depreciable property, when a unit of property is retired, the original cost of that property, less any salvage value, is charged to Accumulated depreciation and amortization, consistent with composite depreciation practices. Depreciation expense is calculated using the straight-line method, which allocates the cost of property over its estimated useful life. For DPL’s transmission and distribution assets, straight-line depreciation is applied monthly on an average composite basis using group rates. Depreciation and amortization expense in the Consolidated Statements of Operations is presented net of regulatory deferrals of depreciation expense and also
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
includes amortization of intangible assets and amortization of previously deferred regulatory costs. The following table presents average composite group rates and depreciation expense for each respective period.
Years ended December 31,
$ in millions 2024 2023 2022
Composite group rates 2.9 % 3.2 % 3.3 %
Depreciation expense $ 85.4 $ 78.0 $ 76.7
AES Ohio may receive contributions in aid of construction ("CIAC") from customers that are intended to defray all or a portion of the costs for certain capital projects, to the extent the project does not benefit regulated customers in general. AES Ohio accounts for CIAC as a reduction to property, plant and equipment.
AFUDC
In accordance with the Uniform System of Accounts prescribed by FERC, AES Ohio capitalizes an allowance for the net cost of funds (interest on borrowed funds and a reasonable rate of return on equity funds) used for construction purposes during the period of construction with a corresponding credit to income. AFUDC equity and AFUDC debt were as follows for the years ended December 31, 2024, 2023 and 2022:
Years ended December 31,
$ in millions 2024 2023 2022
AFUDC equity $ 6.2 $ 5.0 $ 5.7
AFUDC debt $ 7.7 $ 6.5 $ 1.3
Impairment of Long-lived Assets
GAAP requires that we test long-lived assets for impairment when indicators of impairment exist. If an asset is deemed to be impaired, we are required to write down the asset to its fair value with a charge to current earnings. The net book value of our property, plant, and equipment was $2,571.4 million and $2,221.0 million as of December 31, 2024 and 2023, respectively. We do not believe any of these assets are currently impaired. In making this assessment, we consider such factors as: the overall condition and distribution capacity of the assets; the expected ability to recover additional expenditures in the assets; and the anticipated demand and relative pricing of retail electricity in our service territory.
Intangible Assets
Intangibles include software and renewable energy credits. Renewable energy credits are carried on a weighted average cost basis and amortized as they are used or retired. Finite-lived intangible assets include capitalized software amortized on a straight-line basis over their estimated useful lives. These capitalized software intangible assets have a 12.6 year-weighted average amortization period.
The following table presents information related to the Company's capitalized software balances, including the gross amount capitalized and related amortization:
December 31,
$ in millions 2024 2023

Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
Implementation Costs Related to Software as a Service
DPL has recorded prepayments for implementation costs related to software as a service in support of utility customer services which are recorded within Prepayments and other current assets and Other non-current assets on the accompanying Consolidated Balance Sheets as follows:
December 31,
$ in millions 2024 2023
Implementation costs $ 4.0 $ 14.8
Debt Issuance Costs
Costs incurred in connection with the issuance of long-term debt are deferred and presented as a direct reduction from the face amount of that debt and amortized over the related financing period using the effective interest method. Debt issuance costs related to a line-of-credit or revolving credit facility are deferred and presented as an asset and amortized over the related financing period. Make-whole payments in connection with early debt retirements are classified as cash flows from financing activities.
Contingencies
DPL accrues for loss contingencies when the amount of the loss is probable and estimable. We are subject to various environmental regulations and are involved in certain legal proceedings. If DPL’s actual environmental and/or legal obligations are different from our estimates, the recognition of the actual amounts may have a material impact on our results of operations, financial condition and cash flows; although that has not been the case during the periods covered by this report. Accruals for loss contingencies were not material as of December 31, 2024 and 2023. See Note 10. Contractual Obligations, Commercial Commitments and Contingencies for additional information.
Financial Instruments
Our Master Trust investments in debt and equity financial instruments of publicly traded entities are classified as equity investments. These equity securities are carried at fair value and unrealized gains and losses on these securities are recorded in Other income. As these financial instruments are held to be used for the benefit of employees or former employees participating in employee benefit plans and are not used for general operating purposes, they are recorded within Other non-current assets on the accompanying Consolidated Balance Sheets. See Note 4. Fair Value for more information.
Financial Derivatives
We have contracts involving the physical delivery of energy. These contracts qualify for the normal purchases and normal sales scope exception in ASC 815 - Derivatives and Hedging, thus we have elected to account for them as accrual contracts, which are not adjusted for changes in fair value.
We have, in the past, used interest rate hedges to manage the interest rate risk of our variable rate debt. We used cash flow hedge accounting when the hedge or a portion of the hedge was deemed to be highly effective, which resulted in changes in fair value being recorded within accumulated other comprehensive loss, a component of shareholder’s equity / (deficit). We elected not to offset net derivative positions in the consolidated financial statements. Accordingly, we did not offset such derivative positions against the fair value of amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral under master netting agreements. See Note 5. Derivative Instruments and Hedging Activities for more information.
Leases
We have operating leases primarily for office space in which we are the lessee. Operating leases with an initial term of 12 months or less are not recorded on the balance sheet, but are expensed on a straight-line basis over the lease term. Our leases do not contain any material residual value guarantees, restrictive covenants or subleases.
Right-of-use assets represent our right to use an underlying asset for the lease term while lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized on commencement of the lease based on the present value of lease payments over the lease term. Generally, the rate implicit in the lease is not readily determinable; as such, we use the incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We determine discount rates based on the existing credit rates of our borrowings which are then adjusted for the appropriate lease term. The right-of-use asset also includes any lease payments made and excludes lease
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
incentives that are paid or payable to the lessee at commencement. The lease term includes periods covered by the option to extend if it is reasonably certain that the option will be exercised and periods covered by an option to terminate if it is reasonably certain that the option will not be exercised.
Accumulated other comprehensive loss
The changes in the components of Accumulated other comprehensive loss during the years ended December 31, 2024 and 2023 are as follows:
$ in millions Gains / (losses) on cash flow hedges Change in unfunded pension and other postretirement obligations Total

Net current period other comprehensive income / (loss) (0.8) 0.1 (0.7)
Balance at December 31, 2024 $ 10.4 $ (15.7) $ (5.3)
Insurance and Claims Costs
In addition to insurance obtained from third-party providers, MVIC, a wholly-owned captive subsidiary of DPL, provides insurance coverage solely to us and our subsidiaries for workers’ compensation, general liability and property damage on an ongoing basis. Estimates of the liabilities for insurance and claims costs associated with MVIC and the liabilities for medical, life, disability and other reserves for claims costs below certain coverage thresholds of third-party providers are as follows:
Balance Sheet December 31,
$ in millions Classification 2024 2023
Estimated insurance and claims costs Accrued and other current liabilities $ 2.2 $ 1.8
Estimated liabilities for medical, life, disability and other reserves Accrued and other current liabilities and Other non-current liabilities
$ 7.3 $ 8.0
The estimated liabilities for workers’ compensation, medical, life and disability costs at DPL are actuarially determined using certain assumptions. There is uncertainty associated with these loss estimates, and actual results may differ from the estimates. Modification of these loss estimates based on experience and changed circumstances is reflected in the period in which the estimate is re-evaluated.
Revenue Recognition
Revenue is recognized from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Energy sales to customers are based on the reading of their meters that occurs on a systematic basis throughout the month. We recognize the revenue on our Consolidated Statements of Operations using an accrual method for retail and other energy sales that have not yet been billed, but where electricity has been consumed. This is termed “unbilled revenue” and is a widely recognized and accepted practice for utilities. At the end of each month, unbilled revenue is determined by the estimation of unbilled energy provided to customers since the date of the last meter reading, estimated line losses, the assignment of unbilled energy provided to customer classes and the average rate per customer class. For more information, see Note 13. Revenue.
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
Accounting for Taxes Collected from Customers and Remitted to Governmental Authorities
AES Ohio collects certain excise taxes levied by state or local governments from its customers. AES Ohio’s excise taxes and certain other taxes are accounted for on a net basis and recorded as a reduction in revenue in the accompanying Consolidated Statements of Operations. The amounts of such taxes were as follows:
Years ended December 31,
$ in millions 2024 2023 2022
Excise taxes collected $ 48.7 $ 46.6 $ 49.2
Repair and Maintenance Costs
Costs associated with maintenance activities are recognized at the time the work is performed. These costs, which include labor, materials and supplies and outside services required to maintain equipment and facilities, are capitalized or expensed based on defined units of property.
Pension and Postretirement Benefits
We recognize in our Consolidated Balance Sheets an asset or liability reflecting the funded status of pension and other postretirement plans with current-year changes from actuarial gains or losses related to our regulated operations, which would otherwise be recognized in AOCL, recorded as a regulatory asset as this can be recovered through future rates. Such changes that are not related to our regulated operations are recognized in AOCL. All plan assets are recorded at fair value. We follow the measurement date provisions of the accounting guidance, which require a year-end measurement date of plan assets and obligations for all defined benefit plans.
We account for and disclose pension and postretirement benefits in accordance with the provisions of GAAP relating to the accounting for pension and other postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the plans. Consistent with the requirements of ASC 715 - Compensation - Retirement Benefits, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans.
See Note 8. Benefit Plans for more information.
Income Taxes
Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of the existing assets and liabilities and their respective income tax bases. We establish an allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. Our tax positions are evaluated under a more likely than not recognition threshold and measurement analysis before they are recognized for consolidated financial statement reporting. Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid within one year. Our policy for interest and penalties is to recognize interest and penalties as a component of the provision for income taxes in the Consolidated Statements of Operations.
Income taxes payable, which are includable in allowable costs for ratemaking purposes in future years, are recorded as regulatory assets or liabilities with a corresponding deferred tax liability or asset. Investment tax credits that reduced federal income taxes in the years they arose have been deferred and are being amortized to income over the useful lives of the properties in accordance with regulatory treatment. See Note 2. Regulatory Matters for more information.
DPL and its subsidiaries file U.S. federal income tax returns as part of the consolidated U.S. income tax return filed by AES. The consolidated tax liability is allocated to each subsidiary based on the separate return method as specified in our tax allocation agreement, and which provides a consistent, systematic and rational approach. See Note 7. Income Taxes for more information.
Related Party Transactions
In the normal course of business, DPL enters into transactions with related parties. All material intercompany accounts and transactions are eliminated in DPL’s Consolidated Financial Statements. See Note 11. Related Party Transactions for more information.

ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption
2023-06 Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative In U.S. Securities and Exchange Commission (SEC) Release No. 33-10532, Disclosure Update and Simplification, issued August 17, 2018, the SEC referred certain of its disclosure requirements that overlap with, but require incremental information to, generally accepted accounting principles (GAAP) to the FASB for potential incorporation into the Codification. The amendments in this Update are the result of the Board’s decision to incorporate into the Codification 14 of the 27 disclosures referred by the SEC.
The amendments in this Update represent changes to clarify or improve disclosure and presentation requirements of a variety of Topics. Many of the amendments allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the SEC’s requirements. Also, the amendments align the requirements in the Codification with the SEC’s regulations.
The effective date for each amendment will be the date on which the SEC's removal of that related disclosure becomes effective, with early adoption prohibited. The amendments in this Update should be applied prospectively We will provide the required disclosures on a prospective basis on the date each amendment becomes effective. We do not expect ASU 2023-06 will have any impact on our Consolidated Financial Statements.
2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures The amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. Furthermore, companies are required to disclose a disaggregated amount of income taxes paid at a federal, state, and foreign level as well as a break down of income taxes paid in a jurisdiction that comprises 5% of a company's total income taxes paid. Lastly, this ASU requires that companies disclose income (loss) from continuing operations before income tax at a domestic and foreign level and that companies disclose income tax expense from continuing operations on a federal, state, and foreign level. The amendments in this Update are effective for fiscal years beginning after December 15, 2024 We are currently evaluating the impact of adopting the standard on our Consolidated Financial Statements.
2024-03: Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40) The amendments in this Update require disclosure, in the notes to financial statements, of specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity:
1. Disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil- and gas-producing activities (DD&A) (or other amounts of depletion expense) included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (a)-(e).
2. Include certain amounts that are already required to be disclosed under current generally accepted accounting principles (GAAP) in the same disclosure as the other disaggregation requirements.
3. Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively.
4. Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The date for each amendment in this Update is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted We are currently evaluating the impact of adopting the standard on our Consolidated Financial Statements.
2. REGULATORY MATTERS
AES Ohio ESPs and Smart Grid Plans
AES Ohio ESP - 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
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
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 refund of the RSC revenue dating back to August 2021. Oral arguments regarding this appeal have been scheduled for April 22, 2025.
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 pending at the PUCO 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 have been scheduled for April 2, 2025.
Smart Grid Phase 2 Plan - In February 2024, AES Ohio filed a Smart Grid Phase 2 with the PUCO proposing a ten-year investment plan to begin after Smart Grid Phase 1 ends. On September 13, 2024, AES Ohio reached a settlement with the PUCO staff and other parties on the pending Smart Grid Phase 2 application. The settlement provides for a four-year plan to invest $240.5 million of capital and $18.6 million of operations and maintenance expenses related to grid modernization, support of Distributed Energy Resources, Economic Development and an enhanced Telecommunications network. These costs will be recovered through the existing Infrastructure Investment Rider. If approved, AES Ohio will implement a comprehensive grid modernization project that will deliver benefits to customers, society as a whole and to AES Ohio. An evidentiary hearing was held on October 29, 2024, and we expect an order from the PUCO by the second quarter of 2025, prior to the end of Smart Grid Phase 1.
ESP 4 - On September 26, 2022, AES Ohio filed its latest ESP (ESP 4) with the PUCO. ESP 4 is a comprehensive plan to enhance and upgrade its network and improve service reliability, provide greater safeguards for price stability and continue investments in local economic development.
On April 10, 2023, AES Ohio entered into a Stipulation and Recommendation with the PUCO Staff and seventeen parties (the “ESP 4 Settlement”) with respect to AES Ohio’s ESP 4 application, and, on August 9, 2023, the PUCO approved the ESP 4 Settlement without modification. The approved ESP 4 Settlement provides for a three-year plan including the following:
•A Distribution Investment Rider for the term of the ESP allowing for the timely recovery of distribution investments by AES Ohio based on a 9.999% return on equity, subject to revenue caps;
•The recovery of approximately $66.0 million related to past expenditures by AES Ohio plus future carrying costs and the recovery of incremental vegetation management expenses up to certain annual limits during the term of ESP 4. During the third quarter of 2023, AES Ohio deferred $28.3 million of previously recognized purchased power costs and an additional $10.7 million of carrying costs related to this recovery; and
•Funding of programs for assistance to low-income customers and for economic development.
Additionally, with approval of this Settlement, the distribution rates that were approved by the PUCO on December 14, 2022, and are described in the paragraph below, became effective on September 1, 2023.
Distribution Rate Cases
2024 Distribution Rate Case application - On November 29, 2024, AES Ohio filed a new 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:
•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;
•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
•A date certain of September 30, 2024 and a test period of June 1, 2024 - May 31, 2025
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
The rate case application also includes a proposal for increased tree-trimming expenses. AES Ohio proposed an evidentiary hearing be held beginning June 2, 2025; however, the PUCO has not yet established a procedural schedule for the proceeding.
2020 Distribution Rate Case - On November 30, 2020, AES Ohio filed a new distribution rate case application with the PUCO to increase AES Ohio’s base rates for electric distribution service to address, in part, increased costs of materials and labor and substantial investments to improve distribution structures. On December 14, 2022, the PUCO issued an order on the application. Among other matters, the order:
•Establishes a revenue increase of $75.6 million for AES Ohio’s base rates for electric distribution service; and
•Provides for a return on equity of 9.999% and a cost of long-term debt of 4.4% on a distribution rate base of $783.5 million and based on a capital structure of 53.87% equity and 46.13% long-term debt.
These rates went into effect on September 1, 2023 with the approval of AES Ohio's ESP 4, as discussed above.
FERC Transmission Rates
On March 3, 2020, AES Ohio filed an application before the FERC seeking to change its stated transmission rates to formula transmission rates that would be updated each calendar year. An uncontested settlement was filed December 10, 2020 and approved April 15, 2021. Among other things, the settlement established new depreciation rates for AES Ohio’s transmission assets, an authorized return on equity of 9.85%, and started an amortization process to return excess deferred taxes created by the TCJA. Pursuant to the approved mechanisms and formula, transmission rates are adjusted each calendar year to reflect projected costs, adjusted to a true-up of actual revenue and costs incurred in the prior year.
Regulatory Assets and Liabilities
Regulatory assets and liabilities represent deferred costs or credits that have been included as allowable costs or credits for ratemaking purposes. AES Ohio has recorded regulatory assets or liabilities relating to certain costs or credits as authorized by the PUCO or established regulatory practices in accordance with ASC 980. See Note 1. Overview and Summary of Significant Accounting Policies for accounting policies regarding Regulatory Assets and Liabilities.

Current regulatory assets and liabilities
Current regulatory assets primarily represent costs that are being recovered per specific rate orders; recovery for the remaining costs is probable, but not certain. Current regulatory assets include: (i) the Energy Efficiency Rider, (ii) the Transmission Cost Recovery Rider, (iii) the Storm Cost Rider, (iv) the Legacy Generation Rider, (v) the Infrastructure Investment Rider, (vi) the Regulatory Compliance Rider, (vii) the Proactive Reliability Optimization Rider, and (viii) the Distribution Investment Rider. Also included are the current portion of deferred rate case costs, vegetation management, uncollectible expense costs, and the transmission formula rate true-up.
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
Current regulatory liabilities include the overcollection of standard offer costs and certain transmission related costs, including the current portion of the PJM transmission enhancement settlement (discussed below), the transmission rate true-up, the Transmission Cost Recovery Rider overcollection and the TCJA regulatory liability.
AES Ohio is earning a return on $16.2 million of the net undercollections / (overcollections) to be collected / (refunded) through rate riders including: (i) the Energy Efficiency Rider, (ii) the Transmission Cost Recovery Rider, and (iii) the Regulatory Compliance Rider, partially offset by the overcollection of standard offer costs.
Pension benefits
Pension benefits represent the qualifying ASC 715 costs of our regulated operations that for ratemaking purposes are deferred for future recovery. We recognize an asset for a plan’s overfunded status or a liability for a plan’s underfunded status, and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. This regulatory asset represents the regulated portion that would otherwise be charged as a loss to OCI. As per PUCO and FERC precedents, these costs are probable of future rate recovery.
Regulatory compliance costs
Regulatory compliance costs represent the long-term portion of the regulatory compliance costs which include the following costs: (i) Consumer Education Campaign, (ii) Retail Settlement System, (iii) Generation Separation, (iv) Bill Format Redesign, (v) Green Pricing Tariff, (vi) Supplier Consolidated Billing, (vii) Decoupling, (viii) a portion of previously deferred uncollectible costs, and (ix) unrecovered purchased power deferrals, and related carrying charges, approved in ESP 4. The balance of this regulatory asset earns a return with a maximum total to be accrued of $4.0 million. These costs are being recovered over a five-year period that began September 2023 through the Regulatory Compliance Rider approved in ESP 4.
Energy Efficiency Rider
Energy Efficiency Rider represents deferred expense and shared savings associated with energy efficiency programs that provide incentives and rebates for customers to improve the way they use electricity. The deferred expenses and shared savings were incurred prior to Ohio’s energy efficiency change in legislation and are therefore probable for recovery. The PUCO is currently conducting a prudency review, and a PUCO staff report was issued on February 2, 2024.
Smart Grid and AMI costs
Smart Grid and AMI costs represent costs incurred as a result of studying and developing distribution system upgrades and implementation of AMI related to Smart Grid Phase 1 and 2. AES Ohio developed Smart Grid Phase 1, which focuses on implementing new technology in the distribution business to upgrade customer meters, provide new customer programs related to energy efficiency and time-based rates, make certain infrastructure improvements, and upgrade substation and telecommunication equipment. Smart Grid Phase 1 costs are being recovered over a period of 4 years. AES Ohio has proposed Smart Grid Phase 2, which is pending before the PUCO.
Unamortized loss on reacquired debt
Unamortized loss on reacquired debt represents losses on long-term debt reacquired or redeemed in prior periods that have been deferred. These deferred losses are being amortized over the lives of the original issues in accordance with the rules of the FERC and the PUCO.
Deferred storm costs
Deferred storm costs represent the long-term portion of deferred costs for major storms. AES Ohio files semi-annual petitions seeking recovery of storm costs with all costs related to 2024 to be recovered in 2025. Recovery of these costs is probable, but not certain.
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
Rate case expenses
Rate case expenses represent costs associated with preparing distribution rate cases. AES Ohio was granted recovery of the 2020 rate case costs through base rates over a period of 5 years, without a rate of return. AES Ohio has requested approval and recovery of the 2024 rate case costs through the 2024 rate case application, which is pending before the PUCO.
Vegetation management costs
Vegetation management costs represent costs incurred from outside contractors for tree trimming and other vegetation management services. Historically deferred costs from 2018-2020 are being recovered in base rates with an amortization period of five years. In addition, ESP 4 approved a Proactive Reliability Optimization Rider which granted recovery of costs deferred starting from 2021 forward with an annual baseline of $20.0 million, subject to an annual maximum deferral of $7.5 million. These historical costs are also being recovered with an amortization period of five years. Annual spending less than the vegetation management baseline amount will result in a reduction to the regulatory asset or creation of a regulatory liability.
CIS replacement costs
Customer Information System (“CIS”) replacement costs represent operation and maintenance expenses associated with the implementation of a new CIS system. Deferral of these costs, subject to an $8.8 million maximum deferral, was approved in the Smart Grid Phase 1 Order, subject to demonstration that the functionality is available and a reasonableness prudence review. Recovery of these costs was requested and approved in Case No. 22-0900-EL-SSO to be included in the new Regulatory Compliance Rider, once the CIS is used and useful.
Transmission formula rate debits/credits
Transmission formula rate assets and liabilities represent the amounts due from/to customers as a result of the implementation of transmission formula rates, which are adjusted each year based on actual revenue and costs from a previous year, as described above under "FERC Transmission Rates".
Customer program costs
Customer Program Costs (“CPR”) represent costs associated with residential off-peak electric vehicle programs to encourage utilization of the distribution grid during off-peak hours, subject to a maximum annual deferral of $0.3 million, and residential low income assistance programs, subject to a maximum annual deferral of $5.7 million. Deferral of CPR costs were approved in the ESP 4 order.
Uncollectible deferral
Uncollectible deferral represents deferred uncollectible expense associated with the nonpayment of electric service, less the revenue associated with the bypassable uncollectible portion of the standard offer rate. The 2023 distribution rate case order established that these costs would be recovered in base rates over a period of five years.
Estimated costs of removal - regulated property
Estimated costs of removal - regulated property reflect an estimate of amounts collected in customer rates for costs that are expected to be incurred in the future to remove existing transmission and distribution property from service when the property is retired.
Deferred income taxes payable through rates
Deferred income taxes payable through rates represent deferred income tax liabilities recognized from the normalization of flow-through items as the result of taxes previously charged to customers. A deferred income tax asset or liability is created from a difference in income recognition between tax laws and accounting methods. As a regulated utility, AES Ohio includes in ratemaking the impacts of current income taxes and changes in deferred income tax liabilities or assets. Accordingly, this liability reflects the estimated deferred taxes AES Ohio expects to return to customers in future periods.
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
TCJA regulatory liability
TCJA regulatory liability represents the long-term portion of both protected and unprotected excess Accumulated Deferred Income Taxes ("ADIT") for both transmission and distribution portions, grossed up to reflect the revenue requirement. As a part of the DRO, AES Ohio agreed that savings from the TCJA attributable to distribution facilities, including the excess ADIT and the regulatory liability, constitute amounts that will be returned to customers. As a result of the TCJA and subsequent DRO, AES Ohio entered into a stipulation to resolve all remaining TCJA items related to its distribution rates, including a proposal to return no less than $4.0 million per year for the first five years unless fully returned in the first five years via a tax savings cost rider for the distribution portion of the balance. On September 26, 2019, an order approved the stipulation in its entirety.
PJM transmission enhancement settlement
PJM transmission enhancement settlement liability represents the transmission enhancement settlement charges for which AES Ohio is due a refund per FERC Order EL05-121-009 issued on May 31, 2018. The Order states that customers are due a refund for part of these charges which will be received starting August 2018 through 2025. Refunds received will be returned to customers via the transmission cost rider.
Postretirement benefits
Postretirement benefits represent the qualifying ASC 715 gains related to our regulated operations that, for ratemaking purposes, are probable of being reflected in future rates. We recognize an asset for a plan’s overfunded status or a liability for a plan’s underfunded status, and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. This regulatory liability represents the regulated portion that would otherwise be reflected as a gain to OCI.

4. FAIR VALUE
The fair value of our financial assets and liabilities approximate their reported carrying amounts. The estimated fair values of our assets and liabilities have been determined using available market information. Because these amounts are estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
Fair Value Hierarchy and Valuation Techniques
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. These inputs are categorized using the market approach as follows for DPL:
•Level 1 - unadjusted quoted prices for identical assets or liabilities in an active market. This includes inputs used for money market accounts that are considered cash equivalents, open-ended mutual funds and exchange-traded funds in the Master Trust. The fair value is determined by reference to quoted market prices and other relevant information generated by market transactions;
•Level 2 - inputs from quoted prices in markets where trading occurs infrequently or quoted prices of instruments with similar attributes in active markets. This includes the common collective trust pension plan assets valued using the net asset value method. See Note 8. Benefit Plans for more information; and
•Level 3 - unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability. These inputs are used for certain debt balances because the notes are not publicly traded. The fair value reflects management’s own assumptions about the inputs used in pricing the liability. Our long-term debt is fair valued for disclosure purposes only.
The fair values of our financial instruments are based on published sources for pricing when possible. We rely on valuation models only when no other method is available to us. The fair value of our financial instruments represents estimates of possible value that may or may not be realized in the future. Valuations of assets and liabilities reflect the value of the instrument including the values associated with counterparty risk. We include our own credit risk and our counterparty’s credit risk in our calculation of fair value using global average default rates based on an annual study conducted by a large rating agency.
We did not have any transfers of the fair values of our financial instruments among Level 1, Level 2 or Level 3 of the fair value hierarchy during the years ended December 31, 2024 and 2023.
These financial instruments are not subject to master netting agreements or collateral requirements and, as such, are presented in the Consolidated Balance Sheets at their gross fair value.
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 investments are recorded at fair value within Other non-current assets on the Consolidated Balance Sheets and are classified as equity securities. Net unrealized gains related to equity investments still held as of December 31, 2024 and 2023 are as follows:
Years ended December 31,

Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
Financial Instruments not Measured at Fair Value in the Consolidated Balance Sheets
Our long-term debt is fair valued for disclosure purposes only and most of the fair values are determined using quoted market prices in inactive markets. These fair value inputs are considered Level 2 in the fair value hierarchy. As the Wright-Patterson Air Force Base note is not publicly traded, the fair value inputs are considered Level 3 in the fair value hierarchy as there are no observable inputs. Unrealized gains or losses are not recognized in the financial statements as long-term debt is presented at carrying value, net of unamortized premium or discount and unamortized deferred financing costs in the financial statements. The long-term debt amounts include the current portion payable in the next twelve months and have maturities that range from 2025 to 2061. 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 Consolidated Balance Sheets as of the periods indicated, but for which fair value is disclosed:
Carrying Amount Fair Value at December 31, 2024 Carrying Amount Fair Value at December 31, 2023
$ in millions Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total

5. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
DPL previously entered into interest rate derivative contracts to manage interest rate exposure related to anticipated borrowings of fixed-rate debt. The derivative instruments were used for risk management purposes and were designated as cash flow hedges if they qualified under ASC 815 for accounting purposes. These interest rate derivative contracts were settled in 2013 and we continue to amortize amounts out of AOCL into interest expense.
The following tables provide information on gains recognized in AOCL for the cash flow hedges for the periods indicated:

Significant Transactions
In August 2024, AES Ohio entered into an unsecured $150.0 million 364-day term loan agreement ("$150 million Term Loan Agreement"). The $150 million Term Loan Agreement was fully drawn at closing with the proceeds being used for general corporate purposes. This agreement matures on August 13, 2025, and bears interest at variable rates as described in the $150 million Term Loan Agreement. The $150 million 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 $150 million Term Loan Agreement as short-term indebtedness as it matures in August 2025. Management plans to repay this Term Loan Agreement through a combination of cash from operations, new debt, and equity capital contributions.
On December 28, 2023, AES Ohio completed the offering of (i) $92.5 million in aggregate principal amount of First Mortgage Bonds, 5.49% Series due 2028 and (ii) $107.5 million aggregate principal amount of its First Mortgage Bonds, 5.70% Series due 2033 in a private placement. The proceeds from the offerings were used to repay existing indebtedness, including amounts outstanding under the AES Ohio Credit Agreement, and for general corporate purposes.
On April 13, 2023, AES Ohio issued $100.0 million in aggregate principal amount of First Mortgage Bonds, 5.19% Series due 2033 in a private placement. The proceeds from the offering were used to repay amounts outstanding under the AES Ohio Credit Agreement and for general corporate purposes.
DPL's Senior Unsecured Notes
DPL has $415.0 million of 4.125% Senior unsecured notes due July 1, 2025 ("2025 DPL Notes"). Although current liquid funds are not sufficient to repay the amounts due under the 2025 DPL Notes at maturity, we will use a portion of the proceeds from the Closings to repay the notes in full (see Note 1. Overview and Summary of Significant Accounting Policies - Agreement to Sell Minority Interest in AES Ohio for more information).
Debt Covenants and Restrictions
The AES Ohio Credit Agreement and Fifty-Third, Fifty-Fourth and Fifty-Fifth Supplemental Indentures, 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, each contain one financial covenant, respectively. The covenant measures Total Debt to Total Capitalization and is calculated, at the end of each fiscal quarter, by dividing total debt by total capitalization. AES Ohio’s Total Debt to Total Capitalization ratio shall not be greater than 0.67 to 1.00. As of December 31, 2024, AES Ohio was in compliance with this financial covenant.
AES Ohio does not have any meaningful restrictions in its debt financing documents prohibiting distributions to its parent, DPL. As of December 31, 2024, AES Ohio and DPL were in compliance with all debt covenants, including the financial covenants described above.

Deferred Income Taxes
Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and (b) operating loss carryforwards. These items are stated at the enacted tax rates that are expected to be in effect when taxes are actually paid or recovered. Investment tax credits related to utility property have been deferred and are being amortized over the estimated useful lives of the related property.

Uncertain Tax Positions
We apply the provisions of GAAP relating to the accounting for uncertainty in income taxes. The balance of unrecognized tax benefits did not change in 2024 and was $0.4 million at December 31, 2024 and 2023.
The amount anticipated to result in a net decrease to unrecognized tax benefits within 12 months of December 31, 2024 is estimated to be $0.0 million.
The following table presents the changes to our uncertain tax positions:
$ in millions 2024 2023 2022
Unrecognized tax benefits at January 1 $ 0.4 $ 0.4 $ 0.4
Gross increases - current period tax positions - - -
Gross decreases - prior period tax positions - - -
Unrecognized tax benefits at December 31 $ 0.4 $ 0.4 $ 0.4
Tax years subsequent to 2020 remain open to examination by taxing authorities. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, we believe we have appropriately accrued for our uncertain tax positions. However, audit outcomes and the timing of audit settlements and future events that would impact our previously recorded unrecognized tax benefits are subject to significant uncertainty. It is possible that the ultimate outcome of future examinations may exceed our provision for current unrecognized tax benefits.
We recognize interest and penalties related to unrecognized tax benefits in Income tax benefit. The amounts accrued and the tax expense / (benefit) recorded were not material for each period presented.
DPL is no longer subject to U.S. federal income tax examinations for tax years through 2020, but all subsequent periods are open. DPL is no longer subject to state income tax examinations for tax years through 2020 but all subsequent periods are open.
8. BENEFIT PLANS
Postretirement Benefits
Qualified employees who retired prior to 1987 and their dependents are eligible for health care and life insurance benefits until their death, while qualified employees who retired after 1987 are eligible for life insurance benefits and partially subsidized health care. The partially subsidized health care is at the election of the employee, who pays most of the cost, and is available only from their retirement until they are covered by Medicare. We have funded a portion of the union-eligible benefits using a Voluntary Employee Beneficiary Association Trust. These postretirement health care benefits and the related unfunded obligation of $7.9 million and $7.2 million at December 31, 2024 and 2023, respectively, were not material to the Consolidated Financial Statements in the periods covered by this report.
Defined Contribution Plans
The 401(k) Plans are qualified under Section 401 of the Internal Revenue Code.
Participants may elect to contribute up to 85% of eligible compensation to their plans. The existing non-union plan provides that participant contributions are matched 100% on the first 1% of eligible compensation and 50% on the next 5% of eligible compensation and they are fully vested in their employer contributions after 2 years of service. Union participant contributions are matched 150% but are capped at $2,850 for 2024 and they are fully vested in their employer contributions after 3 years of service. Non-union and union employees become eligible to participate in their respective plan upon date of hire. All participants are fully vested in their own contributions. Effective December 31, 2024, non-union participants hired after December 31, 2010, in the existing non-union 401(k) plan were frozen regarding the non-union 401(k) plan and became eligible for The AES Corporation Retirement Savings
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
Plan ("RSP"). The RSP matches 100% of contributions on the first 5% of eligible compensation and also provides for a non-matching contribution of 4% of eligible compensation. Matching contributions in this plan are fully vested while non-matching contributions vest ratably over 5 years of service with AES or its affiliates.
We contributed $3.8 million, $3.5 million and $3.3 million for the years ended December 31, 2024, 2023 and 2022, respectively. AES Ohio matching contributions are paid bi-weekly, in arrears. The contributions by year may include the bi-weekly matching contribution that is paid in the following year in addition to employer matching true-up contributions. AES Ohio also contributes an annual bonus to the accounts of its union participants. This payment is typically made in January of the following year.
Defined Benefit Plans
AES Ohio sponsors a traditional defined benefit pension plan for most of the employees of DPL and its subsidiaries. For collective bargaining employees, the defined benefits are based on a specific dollar amount per year of service. For all other employees (management employees), the traditional defined benefit pension plan is based primarily on compensation and years of service. As of December 31, 2010, this traditional pension plan formula was closed to new management employees. A participant is 100% vested in all amounts credited to their account upon the completion of five vesting years, as defined in The Dayton Power and Light Company Retirement Income Plan, or the participant’s death or disability. If a participant’s employment is terminated, other than by death or disability, prior to such participant becoming 100% vested in his or her account, the account shall be forfeited as of the date of termination. Employees that transferred from AES Ohio to the Service Company maintain their previous eligibility to participate in the AES Ohio pension plan.
Almost all management employees beginning employment on or after January 1, 2011, participated in a cash balance pension plan formula. Similar to the traditional pension plan for management employees, the cash balance benefits were based on compensation and years of service. Effective December 31, 2024, this cash balance pension plan formula was closed to new management employees and will no longer add new pay credits but will continue to provide quarterly interest credits for these participants. A cash balance participant becomes 100% vested in all amounts credited to his or her account upon the completion of three vesting years, as defined in The Dayton Power and Light Company Retirement Income Plan, or the participant’s death or disability. If a participant’s employment is terminated, other than by death or disability, prior to such participant becoming 100% vested in his or her account, the account shall be forfeited as of the date of termination. Vested benefits in the cash balance plan are fully portable upon termination of employment.
In addition, we have a Supplemental Executive Retirement Plan ("SERP") for certain retired key executives. The SERP has an immaterial unfunded liability related to agreements for retirement benefits of certain terminated and retired key executives.
We recognize an asset for a plan’s overfunded status and a liability for a plan’s underfunded status and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. For the transmission and distribution areas of our electric business, these amounts are recorded as regulatory assets and liabilities, which represent the regulated portion that would otherwise be charged or credited to AOCL. We have historically recorded these costs on an accrual basis, and this is how these costs have been historically recovered through customer rates. This factor, combined with the historical precedents from the PUCO and FERC, make these costs probable of future rate recovery.

Significant Gains and Losses Related to Changes in the Benefit Obligation
The actuarial gain of $12.4 million decreased the benefit obligation for the year ended December 31, 2024 and an actuarial loss of $9.6 million increased the benefit obligation for the year ended December 31, 2023. The actuarial gain in 2024 was primarily due to an increase in the discount rate and the actuarial loss in 2023 was primarily due to a decrease in the discount rate.
Assumptions
Our expected return on plan asset assumptions, used to determine benefit obligations, are based on historical long-term rates of return on investments, which use the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. Current market factors, such as inflation and interest rates, as well as asset diversification and portfolio rebalancing, are evaluated when long-term capital market assumptions are determined. Peer data and historical returns are reviewed to verify reasonableness and appropriateness.
At December 31, 2024, we increased the expected long-term rate of return on plan assets assumption to 6.05%. The rate of return represents our long-term assumptions based on our long-term portfolio mix. Also, at December 31, 2024, we increased our assumed discount rate to 5.66% from 5.14% for pension expense to reflect current duration-based yield curve discount rates. A 1% increase / decrease in the rate of return assumption for pension would result in a corresponding decrease / increase in 2025 pension expense of approximately $2.6 million. A 0.25-percentage point increase / decrease in the discount rate for pension would result in a corresponding decrease / increase of approximately $0.4 million to 2025 pension expense.
In determining the discount rate to use for valuing liabilities, we used a market yield curve on high-quality fixed income investments as of December 31, 2024. We project the expected benefit payments under the plan based on participant data and based on certain assumptions concerning mortality, retirement rates, termination rates, etc. The expected benefit payments for each year are then discounted back to the measurement date using the appropriate
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
spot rate for each half-year from the yield curve, thereby obtaining a present value of all expected future benefit payments using the yield curve. Finally, an equivalent single discount rate is determined which produces a present value equal to the present value determined using the full yield curve.
Consistent with the requirements of ASC 715, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans.
In future periods, differences in the actual return on pension plan assets and assumed return, or changes in the discount rate, will affect the timing of contributions, if any, to the plans.
The weighted average assumptions used to determine benefit obligations were:
Benefit Obligation Assumptions Pension
2024 2023 2022
Discount rate for obligations 5.66% 5.14% 5.41%
Rate of compensation increases 3.21% 3.21% 3.21%
Pension Plan Assets
Pension Plan assets are invested in multiple asset classes using a de-risking framework designed to manage the Pension Plan's funded status volatility and minimize future cash contributions. Investment strategies and asset allocations are intended to allocate additional assets to the fixed income asset class should the Pension Plan's funded status improve. Investment performance and asset allocation are measured and monitored on an ongoing basis.
Pension Plan assets are managed in a balanced portfolio comprised of two major components: return seeking assets and liability hedging assets. The expected role of plan return seeking assets is to provide additional return with associated higher levels of risk, while the role of liability hedging assets is to correlate the interest rate of the fixed income investments with that of the Pension Plans' liabilities.
Strategic asset allocation guidelines are determined by a Risk/Advisory Committee and approved by a Fiduciary Committee. These allocations consider the plan’s long-term objectives. The long-term target allocations for plan assets are 30% - 40% for return seeking assets and 60% - 70% for liability hedging assets. Return seeking assets include U.S. and international equity, while liability hedging assets include long-duration and high-yield bond funds and emerging market debt funds.
The investment approach is to move the Pension Plans to a more de-risked position, if and when the overall funded status of the Pension Plans improve, by periodically rebalancing the allocation of the Pension Plans' investments in growth assets and liability hedging assets in accordance with the committee's glide path. This strategy requires the daily monitoring of the Pension Plans' ratio of assets to liabilities in order to determine whether approved trigger points have been met, requiring the rebalancing of the assets.
All plan assets at December 31, 2024 are common collective trusts. With the exception of the cash and cash equivalents, the common collective trusts are valued using the net asset value method and are categorized as Level 2 in the fair value hierarchy. The underlying investments are mutual funds, common stock, or debt securities, in alignment with the target asset allocation.

We contributed $7.5 million, $7.5 million and $7.5 million to the pension plan in the years ended December 31, 2024, 2023 and 2022.
We expect to make contributions of $0.2 million to our SERP in 2025 to cover benefit payments. We also expect to make contributions of $7.5 million to our pension plan during 2025.

Funding for the Pension Plans is based upon actuarially determined contributions that consider the amount deductible for income tax purposes and the minimum contribution required under ERISA, as amended by the Pension Protection Act of 2006, as well as targeted funding levels necessary to meet certain thresholds.
From an ERISA funding perspective, AES Ohio’s funded target liability percentage was estimated to be 95%. In addition, AES Ohio must also contribute the normal service cost earned by active participants during the plan year. The funding of normal cost is expected to be approximately $5.3 million in 2025, which includes $1.2 million for plan expenses. Each year thereafter, if the plan’s underfunding increases to more than the present value of the remaining annual installments, the excess is separately amortized over seven years. AES Ohio’s funding policy for the pension plans is to contribute annually no less than the minimum required by applicable law, and no more than the maximum amount that can be deducted for federal income tax purposes.
Benefit payments, which reflect future service, are expected to be paid as follows:
Estimated future benefit payments
$ in millions due within the following years: Pension
2025 $ 22.0
2026 22.0
2027 21.9

9. SHAREHOLDER'S EQUITY
Common Stock
Effective on the Merger date, DPL's Amended Articles of Incorporation provided for 1,500 authorized common shares, of which one share is outstanding at December 31, 2024.
AES Ohio has 50,000,000 authorized common shares, of which 41,172,173 are outstanding at December 31, 2024. All common shares are held by AES Ohio’s parent, DPL.
Capital Contributions from AES
During the year ended December 31, 2024, DPL received $200.0 million in equity contributions from AES. DPL then made the same investments in AES Ohio.
During the year ended December 31, 2023, DPL received $260.0 million in cash contributions from AES. DPL then made the same investments in AES Ohio. The proceeds from the cash contributions at DPL represented equity contributions of $239.0 million and payments of $21.0 million against the tax receivable from AES.
The proceeds from these equity contributions allow AES Ohio to seek to improve its infrastructure and modernize its grid while maintaining liquidity. DPL did not receive any contributions from AES in 2022.
Dividend Restrictions
DPL’s Amended Articles of Incorporation (the Articles) contain provisions which state that DPL may not make a distribution to its shareholder or make a loan to any of its affiliates (other than its subsidiaries), unless: (a) there exists no Event of Default (as defined in the Articles) and no such Event of Default would result from the making of the distribution or loan; and either (b)(i) at the time of, and/or as a result of, the distribution or loan, DPL’s leverage ratio does not exceed 0.67 to 1.00 and DPL’s interest coverage ratio is not less than 2.50 to 1.00 or, (b)(ii) if such ratios are not within the parameters, DPL’s senior long-term debt rating from one of the three major credit rating agencies is at least investment grade. Further, the restrictions on the payment of distributions to a shareholder and the making of loans to its affiliates (other than subsidiaries) cease to be in effect if the three major credit rating agencies confirm that a lowering of DPL’s senior long-term debt rating below investment grade by the credit rating agencies would not occur without these restrictions.
As described above, DPL’s Amended Articles of Incorporation contain restrictions on DPL’s ability to make dividends, distributions and affiliate loans (other than to its subsidiaries), including restrictions on making such dividends, distributions and loans if certain financial ratios exceed specified levels and DPL’s senior long-term debt rating from a rating agency is below investment grade. As of December 31, 2024, DPL did not meet these
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
requirements and was prohibited under its Articles of Incorporation from making a distribution to its shareholder or making a loan to any of its affiliates (other than its subsidiaries).
10. CONTRACTUAL OBLIGATIONS, COMMERCIAL COMMITMENTS AND CONTINGENCIES
Contractual Obligations and Commercial Commitments
We enter into various contractual obligations and other commercial commitments that may affect the liquidity of our operations. At December 31, 2024, these include:
Payments due in:
$ in millions Total Less than
1 year 2 - 3
years 4 - 5
years More than
5 years
Purchased power commitments
$ 109.1 $ 71.9 $ 37.2 $ - $ -
Purchase orders and other contractual obligations $ 249.9 $ 196.3 $ 52.3 $ 1.3 $ -
Purchased power commitments
AES Ohio enters into long-term contracts for purchased power through the SSO competitive bid auctions. In general, these contracts are subject to variable quantities and are terminable only in limited circumstances.
Purchase orders and other contractual obligations
At December 31, 2024, DPL had various other contractual obligations including contracts to purchase goods and services with various terms and expiration dates. Due to uncertainty regarding the timing and payment of future obligations to the Service Company, and DPL's ability to terminate such obligations upon 90 days' notice, we have excluded such amounts in the contractual obligations table above.
Contingencies
Legal Matters
In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under laws and regulations. We believe the amounts provided in our 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, including the matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in our Consolidated Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided as of December 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; 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; 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 the us and could require us to pay damages or make expenditures in amounts that could be material but could not be estimated as of December 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 December 31, 2024 and December 31, 2023.
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
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 December 31, 2024, AES Ohio could be responsible for the repayment of 4.9%, or $48.8 million, of $1.0 billion OVEC debt obligations if they came due, comprised of both fixed and variable 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.
11. RELATED PARTY TRANSACTIONS
Service Company
The Service Company allocates the costs for services provided based on cost drivers designed to result in fair and equitable allocations. This includes ensuring that the regulated utilities served, including AES Ohio, are not subsidizing costs incurred for the benefit of other businesses.
Benefit Plans
DPL participates in an agreement with Health and Welfare Benefit Plans LLC, an affiliate of AES, to participate in a group benefits program, including but not limited to, health, dental, vision and life benefits. Health and Welfare Benefit Plans LLC administers the financial aspects of the group insurance program, receives all premium payments from the participating affiliates, and makes all vendor payments.
Long-term Compensation Plan
During 2024, 2023 and 2022, some of DPL’s non-union employees received benefits under the AES Long-term Compensation Plan, a deferred compensation program. This type of plan is a common employee retention tool used in our industry. Benefits under this plan are granted in the form of performance units payable in cash and AES restricted stock units. Restricted stock units vest ratably over a three-year period. The performance units payable in cash vest at the end of the three-year performance period and are subject to certain AES performance criteria. Total deferred compensation expense for the years ended December 31, 2024, 2023 and 2022 was not material and is included in Operation and maintenance on DPL’s Consolidated Statements of Operations. The value of these benefits is being recognized over the 36-month vesting period and a portion is recorded as miscellaneous deferred credits with the remainder included in Other paid-in capital on DPL’s Consolidated Balance Sheets in accordance with ASC 718 - Compensation - Stock Compensation.

DPL Capital Trust II
DPL has a wholly-owned business trust, DPL Capital Trust II (the Trust), formed for the purpose of issuing trust capital securities to third-party investors. Effective in 2003, DPL deconsolidated the Trust upon adoption of the accounting standards related to variable interest entities and currently treats the Trust as a nonconsolidated subsidiary. The Trust holds mandatorily redeemable trust capital securities. The investment in the Trust, which
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
amounted to $0.1 million and $0.2 million at December 31, 2024 and 2023, respectively, is included in Other non-current assets on the Consolidated Balance Sheets. DPL also has a note payable to the Trust amounting to $15.6 million and $15.6 million at December 31, 2024 and 2023, respectively, that was established upon the Trust’s deconsolidation in 2003. This note payable is included in Long-term debt on the Consolidated Balance Sheets.
In addition to the obligations under the note payable mentioned above, DPL also agreed to a security obligation which represents a full and unconditional guarantee of payments to the capital security holders of the Trust.
Income Taxes
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.
12. BUSINESS SEGMENTS
DPL manages its business through one reportable operating segment, the Utility 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 DPL and are the most relevant measures considered in DPL’s internal evaluation of the financial performance of its segment. The Chief Operating Decision Maker uses income / (loss) before income tax and net income / (loss) in the annual budget and forecasting process, including making decisions on reinvesting profits to support Utility segment growth. On a monthly basis, the Chief Operating Decision Maker reviews variances in budget versus actual results and monitors changes in forecasted results to assess the underlying operating performance and analyze risks and opportunities for the Utility segment.
The Utility segment is comprised of AES Ohio, a public electric transmission and distribution utility, with all other nonutility business activities aggregated separately. See Note 1. Overview and Summary of Significant Accounting Policies for further information on AES Ohio. The “Other” nonutility category primarily includes interest expense, cash and other immaterial balances. The accounting policies of the identified segment are consistent with those policies and procedures described in the summary of significant accounting policies.
The following tables present financial information for DPL’s reportable business segment:

13. 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 of promised goods or services 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.
Notes to Consolidated Financial Statements - DPL Inc. Table of Contents
Retail revenue
AES Ohio energy sales to utility customers are based on the reading of meters at the customer's location that occurs on a systematic basis throughout the month. AES Ohio sells electricity directly to end-users, such as homes and businesses, and bills customers directly. Performance obligations for retail revenue are satisfied over time as energy is delivered and the same method is used to measure progress, and thus the performance obligation meets the criteria to be considered a series. This includes both the promise to transfer energy and other distribution and/or transmission services.
In exchange for the exclusive right to sell or distribute electricity in our service area, AES Ohio is subject to rate regulation by federal and state regulators. This regulation sets the framework for the prices (“tariffs”) that AES Ohio is allowed to charge customers for electricity. Since tariffs are approved by the regulator, the price that AES Ohio has the right to bill corresponds directly with the value to the customer of AES Ohio's performance completed in each period. Therefore, revenue under these contracts is recognized using an output method measured by the MWhs delivered each month at the approved tariff.
In cases where a customer chooses to receive generation services from a CRES provider, the price for generation services is negotiated between the customer and the CRES provider, and AES Ohio only serves as a billing agent if requested by the CRES provider. As such, AES Ohio recognizes the consolidated billing arrangement with the CRES provider on a net basis, thereby recording no revenue for the generation component. Retail revenue from these customers would only be related to transmission and distribution charges.
Wholesale revenue
AES Ohio's share of the power produced at OVEC is sold to PJM and this revenue is classified as Wholesale revenue.
In PJM, the promise to sell energy as wholesale revenue is separately identifiable from participation in the Capacity Market and the two products can be transacted independently of one another. Therefore, wholesale revenue is a separate contract with a single performance obligation. Revenue is recorded based on the quantities (MWh) delivered in each hour during each month at the spot price, making the contract effectively “month-to-month”.
RTO ancillary revenue
Compensation for use of AES Ohio’s transmission assets and compensation for various ancillary services are classified as RTO ancillary revenue. As AES Ohio owns and operates transmission lines in southwest Ohio within PJM, demand charges collected from network customers by PJM are then allocated to the appropriate transmission owners (i.e. AES Ohio) and recognized as transmission revenue.
Transmission revenue has a single performance obligation, as transmission services represent a distinct service. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The price that AES Ohio, as the transmission operator, has the right to bill (received as a credit from PJM) corresponds directly with the value to the customer of performance completed in each period, as the price paid is the allocation of the tariff rate (as approved by the regulator) charged to network participants.
Capacity revenue
AES Ohio records its share of OVEC capacity revenue as Capacity revenue. The capacity price is set through a competitive auction process established by PJM. Depending on the availability and performance of the OVEC units, there may be additional performance bonuses or penalties, which would be recognized only if it becomes probable that such bonus or penalties will be incurred.
RTO capacity revenue has a single performance obligation, as capacity is a distinct good. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The capacity price is set through a competitive auction process established by PJM.

FINANCIAL STATEMENTS
AES Ohio
Notes to Financial Statements - AES Ohio Table of Contents
Report of Independent Registered Public Accounting Firm
To the Shareholder and the Board of Directors of The Dayton Power & Light Company
Opinion on the Financial Statements
We have audited the accompanying balance sheets of The Dayton Power & Light Company, d/b/a AES Ohio, (the Company) as of December 31, 2024 and 2023, the related statements of operations, statements of comprehensive income, statements of shareholder’s equity and statements of cash flows for each of the three years in the period ended December 31, 2024, and the related notes and financial statement schedule listed in the Index at Item 15 (collectively, referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with U.S. generally accepted accounting principles.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting in accordance with the standards of the PCAOB. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that were communicated or required to be communicated to the Board of Directors and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Notes to Financial Statements - AES Ohio Table of Contents
Regulatory Accounting
Description of the Matter As described in Note 1 to the consolidated financial statements, the Company applies the provisions of FASB Accounting Standards Codification 980 “Regulated Operations”, which gives recognition to the ratemaking and accounting practices of the Public Utilities Commission of Ohio and the Federal Energy Regulatory Commission.
Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory liabilities generally represent obligations to provide refunds or future rate reductions to customers for previous overcollections or the deferral of revenues collected for costs that the Company expects to incur in the future. Accounting for the economics of rate regulation affects multiple consolidated financial statement line items, including property, plant, and equipment; regulatory assets and liabilities; revenues; and depreciation expense, and related disclosures in the Company’s consolidated financial statements.
Auditing the Company’s regulatory accounting was complex due to the significant knowledge and experience required to assess the impact of regulatory orders on the consolidated financial statements including understanding the nature of the rate orders issued, or expected to be issued, and to assess the relevance and reliability of audit evidence to support the impacted account balances and disclosures.
How We Addressed the Matter in Our Audit Our audit procedures related to regulatory assets and liabilities included testing the effectiveness of management’s controls, such as the Company’s evaluation of regulatory orders and other developments that may affect the calculation of recorded amounts, the likelihood of recovering regulatory assets and the sufficiency of regulatory liabilities. Our procedures also included testing management’s calculations of recorded amounts, obtaining, reading, and evaluating relevant regulatory orders issued by the PUCO to DP&L, and considering regulatory precedents established by the PUCO, to evaluate the likelihood of recovering regulatory assets, the sufficiency of regulatory liabilities and the accuracy and completeness of required disclosures related to the impacts of rate regulation and regulatory developments.

Notes to Financial Statements
For the years ended December 31, 2024, 2023 and 2022
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 consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, transmission and distribution services are still regulated. AES Ohio has the exclusive right to provide such service to its approximately 537,000 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 only one reportable segment, the Utility segment. In addition to AES Ohio's electric transmission and distribution businesses, the Utility segment includes revenue and costs associated with AES Ohio's investment in OVEC. The terms “we,” “us,” “our” and “ours” are used to refer to AES Ohio.
AES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, AES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses and records regulatory assets when incurred costs are expected to be recovered in future customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs or overcollections of riders.
Agreement to Sell Minority Interest in AES Ohio
On September 13, 2024, DPL entered into (i) a Purchase and Sale Agreement with Astrid Holdings LP ("Investor"), a wholly-owned subsidiary of Caisse de dépôt et placement du Québec ("CDPQ"), pursuant to which DPL agreed to sell to Investor 15% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Holdings, Inc. ("Ohio Holdings" and, such agreement, the "Ohio Holdings Purchase Agreement") for a purchase price of approximately $273 million, subject to adjustment, and (ii) a Purchase and Sale Agreement with Investor, pursuant to which DPL agreed to sell to Investor 17.65% of the issued and outstanding shares of common stock, no par value per share, of AES Ohio Investments, Inc. ("Ohio Investments" and, such agreement, the "Ohio Investments Purchase Agreement" and together with the Ohio Holdings Purchase Agreement, the "Purchase Agreements") for a purchase price of approximately $273 million, subject to adjustment. Upon consummation of the transactions contemplated by the Ohio Holdings Purchase Agreement and the Ohio Investments Purchase Agreement together, the ("Closings"), CDPQ will own an aggregate indirect equity interest in AES Ohio of approximately 30%, with total proceeds to DPL of approximately $546 million, subject to adjustment.
It is anticipated that the Closings will occur on the same day in the first half of 2025. There will be no change in management or operational control of DPL, Ohio Investments, Ohio Holdings or AES Ohio as a result of these transactions.
The purchases and sales of the shares of capital stock of each of Ohio Holdings and Ohio Investments contemplated under each of the Purchase Agreements are subject to the satisfaction of certain customary conditions described in the Purchase Agreements, including, among others, receipt of the approval of the PUCO, the FERC and completion of review by the Committee on Foreign Investments in the United States ("CFIUS"). As of the filing of this report, approval has been received from the FERC and CFIUS has completed its review. In addition, each of the parties to the Purchase Agreements has agreed to customary covenants therein.
In connection with the Closings, Investor, Ohio Investments and DPL will enter into a Shareholders' Agreement with respect to Ohio Investments (the "Shareholders' Agreement"), the form of which has been agreed to by the parties. The Shareholders' Agreement will establish the general framework governing the relationship between and among Investor and the Company, and their respective successors and transferees, as shareholders of Ohio Investments. In addition, Investor, Ohio Holdings and Ohio Investments will also enter into a Shareholders' Agreement with respect to Ohio Holdings with substantially identical terms.

Financial Statement Presentation
AES Ohio does not have any subsidiaries. We have evaluated subsequent events through the date this report was issued.
Reclassifications
Certain amounts from prior periods have been reclassified to conform to the current period presentation.
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 receivables and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits.
Cash and Cash Equivalents
Cash and cash equivalents are stated at cost, which approximates fair value. All highly liquid short-term investments with original maturities of three months or less are considered cash equivalents.
Restricted Cash
Restricted cash includes cash which is restricted as to withdrawal or usage. The nature of the restrictions includes restrictions imposed by agreements related to deposits held as collateral.
The following table summarizes cash, cash equivalents and restricted cash amounts reported within the Balance Sheets that reconcile to the total of such amounts as shown on the Statements of Cash Flows:

Cash and cash equivalents $ 24.6 $ 15.5

Allowance for credit losses (6.1) (0.9)
Total accounts receivable, net $ 106.6 $ 93.1
The following table is a rollforward of our allowance for credit losses related to the accounts receivable balances for the years ended December 31, 2024 and 2023:
December 31,
$ in millions 2024 2023
Allowance for credit losses:
Beginning balance $ 0.9 $ 0.5
Current period provision 8.3 5.4
Write-offs charged against allowances (3.7) (6.0)
Recoveries collected 0.6 1.0
Ending balance $ 6.1 $ 0.9
Notes to Financial Statements - AES Ohio Table of Contents
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 written off when reasonable collections efforts have been exhausted. During 2024, the current period provision and allowance for credit losses 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. We currently anticipate reinstituting the customer disconnections process and collection efforts and write-off processes by the end of the third quarter of 2025.
Inventories
Inventories are carried at average cost, net of reserves, and include materials and supplies used for utility operations.
Regulatory Accounting
As a regulated utility, AES Ohio applies the provisions of ASC 980 - Regulated Operations, which gives recognition to the ratemaking and accounting practices of the PUCO and the FERC. Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory assets have been included as allowable costs for ratemaking purposes, as authorized by the PUCO or established regulatory practices. Regulatory liabilities generally represent obligations to make refunds or future rate reductions to customers for previous over collections or the deferral of revenue collected for costs that AES Ohio expects to incur in the future.
The deferral of costs (as regulatory assets) is appropriate only when the future recovery of such costs is probable. In assessing probability, we consider such factors as specific orders from the PUCO or the FERC, regulatory precedent and the current regulatory environment. To the extent recovery of costs is no longer deemed probable, related regulatory assets would be required to be expensed in current period earnings. Our regulatory assets and liabilities have been created pursuant to a specific order of the PUCO or the FERC or established regulatory practices, such as other utilities under the jurisdiction of the PUCO or the FERC being granted recovery of similar costs. It is probable, but not certain, that these regulatory assets will be recoverable, subject to approval by the PUCO or the FERC. Regulatory assets and liabilities are classified as current or non-current based on the term in which recovery is expected. See Note 2. Regulatory Matters for more information.
Property, Plant and Equipment
New property, plant and equipment additions are stated at cost. For regulated transmission and distribution property, cost includes direct labor and material, allocable overhead expenses and AFUDC. AFUDC represents the cost of borrowed funds and equity used to finance regulated construction projects. Capitalization of AFUDC and interest ceases at either project completion or at the date specified by regulators.
For substantially all depreciable property, when a unit of property is retired, the original cost of that property, less any salvage value, is charged to Accumulated depreciation and amortization, consistent with composite depreciation practices. Depreciation expense is calculated using the straight-line method, which allocates the cost of property over its estimated useful life. For AES Ohio’s transmission and distribution assets, straight-line depreciation is applied monthly on an average composite basis using group rates. Depreciation and amortization expense in the Statements of Operations is presented net of regulatory deferrals of depreciation expense and also includes amortization of intangible assets and amortization of previously deferred regulatory costs. The following table presents average composite group rates and depreciation expense for each respective period.
Years ended December 31,
$ in millions 2024 2023 2022
Composite group rates 2.4 % 2.6 % 2.8 %
Depreciation expense $ 84.1 $ 76.8 $ 75.6
AES Ohio may receive contributions in aid of construction ("CIAC") from customers that are intended to defray all or a portion of the costs for certain capital projects, to the extent the project does not benefit regulated customers in general. AES Ohio accounts for CIAC as a reduction to property, plant and equipment.
Notes to Financial Statements - AES Ohio Table of Contents
AFUDC
In accordance with the Uniform System of Accounts prescribed by FERC, AES Ohio capitalizes an allowance for the net cost of funds (interest on borrowed funds and a reasonable rate of return on equity funds) used for construction purposes during the period of construction with a corresponding credit to income. AFUDC equity and AFUDC debt were as follows for the years ended December 31, 2024, 2023 and 2022:
Years ended December 31,
$ in millions 2024 2023 2022
AFUDC equity $ 6.2 $ 5.0 $ 5.7
AFUDC debt $ 7.7 $ 6.5 $ 1.3
Impairment of Long-lived Assets
GAAP requires that we test long-lived assets for impairment when indicators of impairment exist. If an asset is deemed to be impaired, we are required to write down the asset to its fair value with a charge to current earnings. The net book value of our property, plant, and equipment was $2,546.2 million and $2,195.9 million as of December 31, 2024 and 2023, respectively. We do not believe any of these assets are currently impaired. In making this assessment, we consider such factors as: the overall condition and distribution capacity of the assets; the expected ability to recover additional expenditures in the assets; and the anticipated demand and relative pricing of retail electricity in our service territory.
Intangible Assets
Intangibles include software and renewable energy credits. Renewable energy credits are carried on a weighted average cost basis and amortized as they are used or retired. Finite-lived intangible assets include capitalized software amortized on a straight-line basis over their estimated useful lives. These capitalized software intangible assets have a 12.6 year-weighted average amortization period.
The following table presents information related to the Company's capitalized software balances, including the gross amount capitalized and related amortization:

Implementation Costs Related to Software as a Service
AES Ohio has recorded prepayments for implementation costs related to software as a service in support of utility customer services which are recorded within Prepayments and other current assets and Other non-current assets on the accompanying Balance Sheets as follows:
December 31,
$ in millions 2024 2023
Implementation costs $ 4.0 $ 14.8
Debt Issuance Costs
Costs incurred in connection with the issuance of long-term debt are deferred and presented as a direct reduction from the face amount of that debt and amortized over the related financing period using the effective interest
Notes to Financial Statements - AES Ohio Table of Contents
method. Debt issuance costs related to a line-of-credit or revolving credit facility are deferred and presented as an asset and amortized over the related financing period. Make-whole payments in connection with early debt retirements are classified as cash flows from financing activities.
Contingencies
AES Ohio accrues for loss contingencies when the amount of the loss is probable and estimable. We are subject to various environmental regulations and are involved in certain legal proceedings. If AES Ohio’s actual environmental and/or legal obligations are different from our estimates, the recognition of the actual amounts may have a material impact on our results of operations, financial condition and cash flows; although that has not been the case during the periods covered by this report. Accruals for loss contingencies were not material as of December 31, 2024 and 2023. See Note 9. Contractual Obligations, Commercial Commitments and Contingencies for additional information.
Financial Instruments
Our Master Trust investments in debt and equity financial instruments of publicly traded entities are classified as equity investments. These equity securities are carried at fair value and unrealized gains and losses on these securities are recorded in Other income. As these financial instruments are held to be used for the benefit of employees or former employees participating in employee benefit plans and are not used for general operating purposes, they are recorded within Other non-current assets on the accompanying Balance Sheets. See Note 4. Fair Value for more information.
Financial Derivatives
We have contracts involving the physical delivery of energy. These contracts qualify for the normal purchases and normal sales scope exception in ASC 815 - Derivatives and Hedging, thus we have elected to account for them as accrual contracts, which are not adjusted for changes in fair value.
Leases
We have operating leases primarily for office space in which we are the lessee. Operating leases with an initial term of 12 months or less are not recorded on the balance sheet, but are expensed on a straight-line basis over the lease term. Our leases do not contain any material residual value guarantees, restrictive covenants or subleases.
Right-of-use assets represent our right to use an underlying asset for the lease term while lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized on commencement of the lease based on the present value of lease payments over the lease term. Generally, the rate implicit in the lease is not readily determinable; as such, we use the incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We determine discount rates based on the existing credit rates of our borrowings which are then adjusted for the appropriate lease term. The right-of-use asset also includes any lease payments made and excludes lease incentives that are paid or payable to the lessee at commencement. The lease term includes periods covered by the option to extend if it is reasonably certain that the option will be exercised and periods covered by an option to terminate if it is reasonably certain that the option will not be exercised.

Insurance and Claims Costs
In addition to insurance obtained from third-party providers, MVIC, a wholly-owned captive subsidiary of DPL, provides insurance coverage solely to us and other DPL subsidiaries for workers’ compensation, general liability and property damage on an ongoing basis. Estimates of the liabilities for insurance and claims costs associated with MVIC and the liabilities for medical, life, disability and other reserves for claims costs below certain coverage thresholds of third-party providers are as follows:
Balance Sheet December 31,
$ in millions Classification 2024 2023
Estimated liabilities for medical, life disability and other reserves Accrued and other current liabilities and Other non-current liabilities
$ 3.7 $ 3.5
The estimated liabilities for workers’ compensation, medical, life and disability costs at AES Ohio are actuarially determined using certain assumptions. There is uncertainty associated with these loss estimates, and actual results may differ from the estimates. Modification of these loss estimates based on experience and changed circumstances is reflected in the period in which the estimate is re-evaluated.
Revenue Recognition
Revenue is recognized from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Energy sales to customers are based on the reading of their meters that occurs on a systematic basis throughout the month. We recognize the revenue on our Statements of Operations using an accrual method for retail and other energy sales that have not yet been billed, but where electricity has been consumed. This is termed “unbilled revenue” and is a widely recognized and accepted practice for utilities. At the end of each month, unbilled revenue is determined by the estimation of unbilled energy provided to customers since the date of the last meter reading, estimated line losses, the assignment of unbilled energy provided to customer classes and the average rate per customer class. For more information, see Note 11. Business Segments.
Accounting for Taxes Collected from Customers and Remitted to Governmental Authorities
AES Ohio collects certain excise taxes levied by state or local governments from its customers. AES Ohio’s excise taxes and certain other taxes are accounted for on a net basis and recorded as a reduction in revenue in the accompanying Statements of Operations. The amounts of such taxes were as follows:

Costs associated with maintenance activities are recognized at the time the work is performed. These costs, which include labor, materials and supplies and outside services required to maintain equipment and facilities, are capitalized or expensed based on defined units of property.
Pension and Postretirement Benefits
We recognize in our Balance Sheets an asset or liability reflecting the funded status of pension and other postretirement plans with current-year changes from actuarial gains or losses related to our regulated operations, which would otherwise be recognized in AOCL, recorded as a regulatory asset as this can be recovered through future rates. Such changes that are not related to our regulated operations are recognized in AOCL. All plan assets are recorded at fair value. We follow the measurement date provisions of the accounting guidance, which require a year-end measurement date of plan assets and obligations for all defined benefit plans.
We account for and disclose pension and postretirement benefits in accordance with the provisions of GAAP relating to the accounting for pension and other postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the plans. Consistent with the requirements of ASC 715 - Compensation - Retirement Benefits, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans.
See Note 7. Benefit Plans for more information.
Income Taxes
Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of the existing assets and liabilities and their respective income tax bases. We establish an allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. Our tax positions are evaluated under a more likely than not recognition threshold and measurement analysis before they are recognized for financial statement reporting. Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid within one year. Our policy for interest and penalties is to recognize interest and penalties as a component of the provision for income taxes in the Statements of Operations.
Income taxes payable, which are includable in allowable costs for ratemaking purposes in future years, are recorded as regulatory assets or liabilities with a corresponding deferred tax liability or asset. Investment tax credits that reduced federal income taxes in the years they arose have been deferred and are being amortized to income over the useful lives of the properties in accordance with regulatory treatment. See Note 2. Regulatory Matters for more information.
AES Ohio files U.S. federal income tax returns as part of the consolidated U.S. income tax return filed by AES. The consolidated tax liability is allocated to each subsidiary based on the separate return method as specified in our tax allocation agreement, and which provides a consistent, systematic and rational approach. See Note 6. Income Taxes for more information.
Related Party Transactions
In the normal course of business, AES Ohio enters into transactions with other subsidiaries of DPL or AES. See Note 10. Related Party Transactions for more information.

ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption
2023-06 Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative In U.S. Securities and Exchange Commission (SEC) Release No. 33-10532, Disclosure Update and Simplification, issued August 17, 2018, the SEC referred certain of its disclosure requirements that overlap with, but require incremental information to, generally accepted accounting principles (GAAP) to the FASB for potential incorporation into the Codification. The amendments in this Update are the result of the Board’s decision to incorporate into the Codification 14 of the 27 disclosures referred by the SEC.
The amendments in this Update represent changes to clarify or improve disclosure and presentation requirements of a variety of Topics. Many of the amendments allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the SEC’s requirements. Also, the amendments align the requirements in the Codification with the SEC’s regulations.
The effective date for each amendment will be the date on which the SEC's removal of that related disclosure becomes effective, with early adoption prohibited. The amendments in this Update should be applied prospectively We will provide the required disclosures on a prospective basis on the date each amendment becomes effective. We do not expect ASU 2023-06 will have any impact on our Financial Statements.
2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures The amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. Furthermore, companies are required to disclose a disaggregated amount of income taxes paid at a federal, state, and foreign level as well as a break down of income taxes paid in a jurisdiction that comprises 5% of a company's total income taxes paid. Lastly, this ASU requires that companies disclose income (loss) from continuing operations before income tax at a domestic and foreign level and that companies disclose income tax expense from continuing operations on a federal, state, and foreign level. The amendments in this Update are effective for fiscal years beginning after December 15, 2024 We are currently evaluating the impact of adopting the standard on our Financial Statements.
2024-03: Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40) The amendments in this Update require disclosure, in the notes to financial statements, of specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity:
1. Disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil- and gas-producing activities (DD&A) (or other amounts of depletion expense) included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (a)-(e).
2. Include certain amounts that are already required to be disclosed under current generally accepted accounting principles (GAAP) in the same disclosure as the other disaggregation requirements.
3. Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively.
4. Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The date for each amendment in this Update is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted We are currently evaluating the impact of adopting the standard on our Financial Statements.
2. REGULATORY MATTERS
AES Ohio ESPs and Smart Grid Plans
AES Ohio ESP - 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
Notes to Financial Statements - AES Ohio Table of Contents
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 refund of the RSC revenue dating back to August 2021. Oral arguments regarding this appeal have been scheduled for April 22, 2025.
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 pending at the PUCO 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 have been scheduled for April 2, 2025.
Smart Grid Phase 2 Plan - In February 2024, AES Ohio filed a Smart Grid Phase 2 with the PUCO proposing a ten-year investment plan to begin after Smart Grid Phase 1 ends. On September 13, 2024, AES Ohio reached a settlement with the PUCO staff and other parties on the pending Smart Grid Phase 2 application. The settlement provides for a four-year plan to invest $240.5 million of capital and $18.6 million of operations and maintenance expenses related to grid modernization, support of Distributed Energy Resources, Economic Development and an enhanced Telecommunications network. These costs will be recovered through the existing Infrastructure Investment Rider. If approved, AES Ohio will implement a comprehensive grid modernization project that will deliver benefits to customers, society as a whole and to AES Ohio. An evidentiary hearing was held on October 29, 2024, and we expect an order from the PUCO by the second quarter of 2025, prior to the end of Smart Grid Phase 1.
ESP 4 - On September 26, 2022, AES Ohio filed its latest ESP (ESP 4) with the PUCO. ESP 4 is a comprehensive plan to enhance and upgrade its network and improve service reliability, provide greater safeguards for price stability and continue investments in local economic development.
On April 10, 2023, AES Ohio entered into a Stipulation and Recommendation with the PUCO Staff and seventeen parties (the “ESP 4 Settlement”) with respect to AES Ohio’s ESP 4 application, and, on August 9, 2023, the PUCO approved the ESP 4 Settlement without modification. The approved ESP 4 Settlement provides for a three-year plan including the following:
•A Distribution Investment Rider for the term of the ESP allowing for the timely recovery of distribution investments by AES Ohio based on a 9.999% return on equity, subject to revenue caps;
•The recovery of approximately $66.0 million related to past expenditures by AES Ohio plus future carrying costs and the recovery of incremental vegetation management expenses up to certain annual limits during the term of ESP 4. During the third quarter of 2023, AES Ohio deferred $28.3 million of previously recognized purchased power costs and an additional $10.7 million of carrying costs related to this recovery; and
•Funding of programs for assistance to low-income customers and for economic development.
Additionally, with approval of this Settlement, the distribution rates that were approved by the PUCO on December 14, 2022, and are described in the paragraph below, became effective on September 1, 2023.
Distribution Rate Cases
2024 Distribution Rate Case application - On November 29, 2024, AES Ohio filed a new 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:
•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;
•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
•A date certain of September 30, 2024 and a test period of June 1, 2024 - May 31, 2025
Notes to Financial Statements - AES Ohio Table of Contents
The rate case application also includes a proposal for increased tree-trimming expenses. AES Ohio proposed an evidentiary hearing be held beginning June 2, 2025; however, the PUCO has not yet established a procedural schedule for the proceeding.
2020 Distribution Rate Case - On November 30, 2020, AES Ohio filed a new distribution rate case application with the PUCO to increase AES Ohio’s base rates for electric distribution service to address, in part, increased costs of materials and labor and substantial investments to improve distribution structures. On December 14, 2022, the PUCO issued an order on the application. Among other matters, the order:
•Establishes a revenue increase of $75.6 million for AES Ohio’s base rates for electric distribution service; and
•Provides for a return on equity of 9.999% and a cost of long-term debt of 4.4% on a distribution rate base of $783.5 million and based on a capital structure of 53.87% equity and 46.13% long-term debt.
These rates went into effect on September 1, 2023 with the approval of AES Ohio's ESP 4, as discussed above.
FERC Transmission Rates
On March 3, 2020, AES Ohio filed an application before the FERC seeking to change its stated transmission rates to formula transmission rates that would be updated each calendar year. An uncontested settlement was filed December 10, 2020 and approved April 15, 2021. Among other things, the settlement established new depreciation rates for AES Ohio’s transmission assets, an authorized return on equity of 9.85%, and started an amortization process to return excess deferred taxes created by the TCJA. Pursuant to the approved mechanisms and formula, transmission rates are adjusted each calendar year to reflect projected costs, adjusted to a true-up of actual revenue and costs incurred in the prior year.
Regulatory Assets and Liabilities
Regulatory assets and liabilities represent deferred costs or credits that have been included as allowable costs or credits for ratemaking purposes. AES Ohio has recorded regulatory assets or liabilities relating to certain costs or credits as authorized by the PUCO or established regulatory practices in accordance with ASC 980. See Note 1. Overview and Summary of Significant Accounting Policies for accounting policies regarding Regulatory Assets and Liabilities.

Current regulatory assets and liabilities
Current regulatory assets primarily represent costs that are being recovered per specific rate orders; recovery for the remaining costs is probable, but not certain. Current regulatory assets include: (i) the Energy Efficiency Rider, (ii) the Transmission Cost Recovery Rider, (iii) the Storm Cost Rider, (iv) the Legacy Generation Rider, (v) the Infrastructure Investment Rider, (vi) the Regulatory Compliance Rider, (vii) the Proactive Reliability Optimization Rider, and (viii) the Distribution Investment Rider. Also included are the current portion of deferred rate case costs, vegetation management, uncollectible expense costs, and the transmission formula rate true-up.
Notes to Financial Statements - AES Ohio Table of Contents
Current regulatory liabilities include the overcollection of standard offer costs and certain transmission related costs, including the current portion of the PJM transmission enhancement settlement (discussed below), the transmission rate true-up, the Transmission Cost Recovery Rider overcollection and the TCJA regulatory liability.
AES Ohio is earning a return on $16.2 million of the net undercollections / (overcollections) to be collected / (refunded) through rate riders including: (i) the Energy Efficiency Rider, (ii) the Transmission Cost Recovery Rider, and (iii) the Regulatory Compliance Rider, partially offset by the overcollection of standard offer costs.
Pension benefits
Pension benefits represent the qualifying ASC 715 costs of our regulated operations that for ratemaking purposes are deferred for future recovery. We recognize an asset for a plan’s overfunded status or a liability for a plan’s underfunded status, and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. This regulatory asset represents the regulated portion that would otherwise be charged as a loss to OCI. As per PUCO and FERC precedents, these costs are probable of future rate recovery.
Regulatory compliance costs
Regulatory compliance costs represent the long-term portion of the regulatory compliance costs which include the following costs: (i) Consumer Education Campaign, (ii) Retail Settlement System, (iii) Generation Separation, (iv) Bill Format Redesign, (v) Green Pricing Tariff, (vi) Supplier Consolidated Billing, (vii) Decoupling, (viii) a portion of previously deferred uncollectible costs, and (ix) unrecovered purchased power deferrals, and related carrying charges, approved in ESP 4. The balance of this regulatory asset earns a return with a maximum total to be accrued of $4.0 million. These costs are being recovered over a five-year period that began September 2023 through the Regulatory Compliance Rider approved in ESP 4.
Energy Efficiency Rider
Energy Efficiency Rider represents deferred expense and shared savings associated with energy efficiency programs that provide incentives and rebates for customers to improve the way they use electricity. The deferred expenses and shared savings were incurred prior to Ohio’s energy efficiency change in legislation and are therefore probable for recovery. The PUCO is currently conducting a prudency review, and a PUCO staff report was issued on February 2, 2024.
Smart Grid and AMI costs
Smart Grid and AMI costs represent costs incurred as a result of studying and developing distribution system upgrades and implementation of AMI related to Smart Grid Phase 1 and 2. AES Ohio developed Smart Grid Phase 1, which focuses on implementing new technology in the distribution business to upgrade customer meters, provide new customer programs related to energy efficiency and time-based rates, make certain infrastructure improvements, and upgrade substation and telecommunication equipment. Smart Grid Phase 1 costs are being recovered over a period of 4 years. AES Ohio has proposed Smart Grid Phase 2, which is pending before the PUCO.
Unamortized loss on reacquired debt
Unamortized loss on reacquired debt represents losses on long-term debt reacquired or redeemed in prior periods that have been deferred. These deferred losses are being amortized over the lives of the original issues in accordance with the rules of the FERC and the PUCO.
Notes to Financial Statements - AES Ohio Table of Contents
Deferred storm costs
Deferred storm costs represent the long-term portion of deferred costs for major storms. AES Ohio files semi-annual petitions seeking recovery of storm costs with all costs related to 2024 to be recovered in 2025. Recovery of these costs is probable, but not certain.
Rate case expenses
Rate case expenses represent costs associated with preparing distribution rate cases. AES Ohio was granted recovery of the 2020 rate case costs through base rates over a period of 5 years, without a rate of return. AES Ohio has requested approval and recovery of the 2024 rate case costs through the 2024 rate case application, which is pending before the PUCO.
Vegetation management costs
Vegetation management costs represent costs incurred from outside contractors for tree trimming and other vegetation management services. Historically deferred costs from 2018-2020 are being recovered in base rates with an amortization period of five years. In addition, ESP 4 approved a Proactive Reliability Optimization Rider which granted recovery of costs deferred starting from 2021 forward with an annual baseline of $20.0 million, subject to an annual maximum deferral of $7.5 million. These historical costs are also being recovered with an amortization period of five years. Annual spending less than the vegetation management baseline amount will result in a reduction to the regulatory asset or creation of a regulatory liability.
CIS replacement costs
Customer Information System (“CIS”) replacement costs represent operation and maintenance expenses associated with the implementation of a new CIS system. Deferral of these costs, subject to an $8.8 million maximum deferral, was approved in the Smart Grid Phase 1 Order, subject to demonstration that the functionality is available and a reasonableness prudence review. Recovery of these costs was requested and approved in Case No. 22-0900-EL-SSO to be included in the new Regulatory Compliance Rider, once the CIS is used and useful.
Transmission formula rate debits/credits
Transmission formula rate assets and liabilities represent the amounts due from/to customers as a result of the implementation of transmission formula rates, which are adjusted each year based on actual revenue and costs from a previous year, as described above under "FERC Transmission Rates".
Customer program costs
Customer Program Costs (“CPR”) represent costs associated with residential off-peak electric vehicle programs to encourage utilization of the distribution grid during off-peak hours, subject to a maximum annual deferral of $0.3 million, and residential low income assistance programs, subject to a maximum annual deferral of $5.7 million. Deferral of CPR costs were approved in the ESP 4 order.
Uncollectible deferral
Uncollectible deferral represents deferred uncollectible expense associated with the nonpayment of electric service, less the revenue associated with the bypassable uncollectible portion of the standard offer rate. The 2023 distribution rate case order established that these costs would be recovered in base rates over a period of five years.
Estimated costs of removal - regulated property
Estimated costs of removal - regulated property reflect an estimate of amounts collected in customer rates for costs that are expected to be incurred in the future to remove existing transmission and distribution property from service when the property is retired.
Notes to Financial Statements - AES Ohio Table of Contents
Deferred income taxes payable through rates
Deferred income taxes payable through rates represent deferred income tax liabilities recognized from the normalization of flow-through items as the result of taxes previously charged to customers. A deferred income tax asset or liability is created from a difference in income recognition between tax laws and accounting methods. As a regulated utility, AES Ohio includes in ratemaking the impacts of current income taxes and changes in deferred income tax liabilities or assets. Accordingly, this liability reflects the estimated deferred taxes AES Ohio expects to return to customers in future periods.
TCJA regulatory liability
TCJA regulatory liability represents the long-term portion of both protected and unprotected excess Accumulated Deferred Income Taxes ("ADIT") for both transmission and distribution portions, grossed up to reflect the revenue requirement. As a part of the DRO, AES Ohio agreed that savings from the TCJA attributable to distribution facilities, including the excess ADIT and the regulatory liability, constitute amounts that will be returned to customers. As a result of the TCJA and subsequent DRO, AES Ohio entered into a stipulation to resolve all remaining TCJA items related to its distribution rates, including a proposal to return no less than $4.0 million per year for the first five years unless fully returned in the first five years via a tax savings cost rider for the distribution portion of the balance. On September 26, 2019, an order approved the stipulation in its entirety.
PJM transmission enhancement settlement
PJM transmission enhancement settlement liability represents the transmission enhancement settlement charges for which AES Ohio is due a refund per FERC Order EL05-121-009 issued on May 31, 2018. The Order states that customers are due a refund for part of these charges which will be received starting August 2018 through 2025. Refunds received will be returned to customers via the transmission cost rider.
Postretirement benefits
Postretirement benefits represent the qualifying ASC 715 gains related to our regulated operations that, for ratemaking purposes, are probable of being reflected in future rates. We recognize an asset for a plan’s overfunded status or a liability for a plan’s underfunded status, and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. This regulatory liability represents the regulated portion that would otherwise be reflected as a gain to OCI.

4. FAIR VALUE
The fair value of our financial assets and liabilities approximate their reported carrying amounts. The estimated fair values of our assets and liabilities have been determined using available market information. Because these amounts are estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.
Fair Value Hierarchy and Valuation Techniques
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. These inputs are categorized using the market approach as follows for AES Ohio:
•Level 1 - unadjusted quoted prices for identical assets or liabilities in an active market. This includes inputs used for money market accounts that are considered cash equivalents, open-ended mutual funds and exchange-traded funds in the Master Trust. The fair value is determined by reference to quoted market prices and other relevant information generated by market transactions;
•Level 2 - inputs from quoted prices in markets where trading occurs infrequently or quoted prices of instruments with similar attributes in active markets. This includes the common collective trust pension plan assets valued using the net asset value method. See Note 7. Benefit Plans for more information; and
•Level 3 - unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability. These inputs are used for certain debt balances because the notes are not publicly traded. The fair value reflects management’s own assumptions about the inputs used in pricing the liability. Our long-term debt is fair valued for disclosure purposes only.
The fair values of our financial instruments are based on published sources for pricing when possible. We rely on valuation models only when no other method is available to us. The fair value of our financial instruments represents estimates of possible value that may or may not be realized in the future. Valuations of assets and liabilities reflect the value of the instrument including the values associated with counterparty risk. We include our own credit risk and our counterparty’s credit risk in our calculation of fair value using global average default rates based on an annual study conducted by a large rating agency.
We did not have any transfers of the fair values of our financial instruments among Level 1, Level 2 or Level 3 of the fair value hierarchy during the years ended December 31, 2024 and 2023
These financial instruments are not subject to master netting agreements or collateral requirements and, as such, are presented in the Balance Sheets at their gross fair value.
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 investments are recorded at fair value within Other non-current assets on the Balance Sheets and are classified as equity securities. Net unrealized gains related to equity investments still held as of December 31, 2024 and 2023 are as follows:
Years ended December 31,

Recurring Fair Value Measurements
The fair value of assets at December 31, 2024 and 2023 and the respective category within the fair value hierarchy for AES Ohio was determined as follows:
$ in millions Fair Value at December 31, 2024 Fair Value at December 31, 2023
Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total
Assets
Money market funds $ 0.4 $ - $ - $ 0.4 $ 0.6 $ - $ - $ 0.6
Mutual funds 7.6 - - 7.6 7.2 - - 7.2
Total assets $ 8.0 $ - $ - $ 8.0 $ 7.8 $ - $ - $ 7.8
Financial Instruments not Measured at Fair Value in the Balance Sheets
Our long-term debt is fair valued for disclosure purposes only and most of the fair values are determined using quoted market prices in inactive markets. These fair value inputs are considered Level 2 in the fair value hierarchy. As the Wright-Patterson Air Force Base note is not publicly traded, the fair value inputs are considered Level 3 in the fair value hierarchy as there are no observable inputs. Unrealized gains or losses are not recognized in the financial statements as long-term debt is presented at carrying value, net of unamortized premium or discount and unamortized deferred financing costs in the financial statements. The long-term debt amounts include the current portion payable in the next twelve months and have maturities that range from 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 Balance Sheets as of the periods indicated, but for which fair value is disclosed:

Deferred Income Taxes
Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and (b) operating loss carryforwards. These items are stated at the enacted tax rates that are expected to be in effect when taxes are actually paid or recovered. Investment tax credits related to utility property have been deferred and are being amortized over the estimated useful lives of the related property.

Uncertain Tax Positions
We apply the provisions of GAAP relating to the accounting for uncertainty in income taxes. The balance of unrecognized tax benefits did not change in 2024 and was $0.4 million at December 31, 2024 and December 31, 2023.
The amount anticipated to result in a net decrease to unrecognized tax benefits within 12 months of December 31, 2024 is estimated to be $0.0 million.
The following table presents the changes to our uncertain tax positions:
$ in millions 2024 2023 2022
Unrecognized tax benefits at January 1 $ 0.4 $ 0.4 $ 0.4
Gross increases - current period tax positions - - -
Gross decreases - prior period tax positions - - -
Unrecognized tax benefits at December 31 $ 0.4 $ 0.4 $ 0.4
Tax years subsequent to 2020 remain open to examination by taxing authorities. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, we believe we have appropriately accrued for our uncertain tax positions. However, audit outcomes and the timing of audit settlements and future events that would impact our previously recorded unrecognized tax benefits are subject to significant uncertainty. It is possible that the ultimate outcome of future examinations may exceed our provision for current unrecognized tax benefits.
We recognize interest and penalties related to unrecognized tax benefits in Income tax benefit. The amounts accrued and the tax expense / (benefit) recorded were not material for each period presented.
AES Ohio is no longer subject to U.S. federal income tax examinations for tax years through 2020, but all subsequent periods are open. AES Ohio is no longer subject to state income tax examinations for tax years through 2020, but all subsequent periods are open.
7. BENEFIT PLANS
Postretirement Benefits
Qualified employees who retired prior to 1987 and their dependents are eligible for health care and life insurance benefits until their death, while qualified employees who retired after 1987 are eligible for life insurance benefits and partially subsidized health care. The partially subsidized health care is at the election of the employee, who pays most of the cost, and is available only from their retirement until they are covered by Medicare. We have funded a portion of the union-eligible benefits using a Voluntary Employee Beneficiary Association Trust. These postretirement health care benefits and the related unfunded obligation of $7.9 million and $7.2 million at December 31, 2024 and 2023, respectively, were not material to the Financial Statements in the periods covered by this report.
Defined Contribution Plans
The 401(k) Plans are qualified under Section 401 of the Internal Revenue Code.
Participants may elect to contribute up to 85% of eligible compensation to their plans. The existing non-union plan provides that participant contributions are matched 100% on the first 1% of eligible compensation and 50% on the next 5% of eligible compensation and they are fully vested in their employer contributions after 2 years of service. Union participant contributions are matched 150% but are capped at $2,850 for 2024 and they are fully vested in their employer contributions after 3 years of service. Non-union and union employees become eligible to participate in their respective plan upon date of hire. All participants are fully vested in their own contributions. Effective December 31, 2024, non-union participants hired after December 31, 2010, in the existing non-union 401(k) plan were frozen regarding the non-union 401(k) plan and became eligible for The AES Corporation Retirement Savings Plan ("RSP"). The RSP matches 100% of contributions on the first 5% of eligible compensation and also provides for a non-matching contribution of 4% of eligible compensation. Matching contributions in this plan are fully vested while non-matching contributions vest ratably over 5 years of service with AES or its affiliates.
We contributed $3.8 million, $3.5 million and $3.3 million for the years ended December 31, 2024, 2023 and 2022, respectively. AES Ohio matching contributions are paid bi-weekly, in arrears. The contributions by year may include
Notes to Financial Statements - AES Ohio Table of Contents
the bi-weekly matching contribution that is paid in the following year in addition to employer matching true-up contributions. AES Ohio also contributes an annual bonus to the accounts of its union participants. This payment is typically made in January of the following year.
Defined Benefit Plans
AES Ohio sponsors a traditional defined benefit pension plan for most of the employees of DPL and its subsidiaries. For collective bargaining employees, the defined benefits are based on a specific dollar amount per year of service. For all other employees (management employees), the traditional defined benefit pension plan is based primarily on compensation and years of service. As of December 31, 2010, this traditional pension plan formula was closed to new management employees. A participant is 100% vested in all amounts credited to their account upon the completion of five vesting years, as defined in The Dayton Power and Light Company Retirement Income Plan, or the participant’s death or disability. If a participant’s employment is terminated, other than by death or disability, prior to such participant becoming 100% vested in his or her account, the account shall be forfeited as of the date of termination. Employees that transferred from AES Ohio to the Service Company maintain their previous eligibility to participate in the AES Ohio pension plan.
Almost all management employees beginning employment on or after January 1, 2011, participated in a cash balance pension plan formula. Similar to the traditional pension plan for management employees, the cash balance benefits were based on compensation and years of service. Effective December 31, 2024, this cash balance pension plan formula was closed to new management employees and will no longer add new pay credits but will continue to provide quarterly interest credits for these participants. A cash balance participant becomes 100% vested in all amounts credited to his or her account upon the completion of three vesting years, as defined in The Dayton Power and Light Company Retirement Income Plan, or the participant’s death or disability. If a participant’s employment is terminated, other than by death or disability, prior to such participant becoming 100% vested in his or her account, the account shall be forfeited as of the date of termination. Vested benefits in the cash balance plan are fully portable upon termination of employment.
In addition, we have a Supplemental Executive Retirement Plan ("SERP") for certain retired key executives. The SERP has an immaterial unfunded liability related to agreements for retirement benefits of certain terminated and retired key executives.
We recognize an asset for a plan’s overfunded status and a liability for a plan’s underfunded status and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. For the transmission and distribution areas of our electric business, these amounts are recorded as regulatory assets and liabilities, which represent the regulated portion that would otherwise be charged or credited to AOCL. We have historically recorded these costs on an accrual basis, and this is how these costs have been historically recovered through customer rates. This factor, combined with the historical precedents from the PUCO and FERC, make these costs probable of future rate recovery.

Significant Gains and Losses Related to Changes in the Benefit Obligation
The actuarial gain of $12.4 million decreased the benefit obligation for the year ended December 31, 2024 and an actuarial loss of $9.6 million increased the benefit obligation for the year ended December 31, 2023. The actuarial gain in 2024 was primarily due to an increase in the discount rate and the actuarial loss in 2023 was primarily due to a decrease in the discount rate.
Assumptions
Our expected return on plan asset assumptions, used to determine benefit obligations, are based on historical long-term rates of return on investments, which use the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. Current market factors, such as inflation and interest rates, as well as asset diversification and portfolio rebalancing, are evaluated when long-term capital market assumptions are determined. Peer data and historical returns are reviewed to verify reasonableness and appropriateness.
At December 31, 2024, we increased the expected long-term rate of return on plan assets assumption to 6.05%. The rate of return represents our long-term assumptions based on our long-term portfolio mix. Also, at December 31, 2024, we increased our assumed discount rate to 5.66% from 5.14% for pension expense to reflect current duration-based yield curve discount rates. A 1% increase / decrease in the rate of return assumption for pension would result in a corresponding decrease / increase in 2025 pension expense of approximately $2.6 million. A 0.25-percentage point increase / decrease in the discount rate for pension would result in a corresponding decrease / increase of approximately $0.4 million to 2025 pension expense.
In determining the discount rate to use for valuing liabilities, we used a market yield curve on high-quality fixed income investments as of December 31, 2024. We project the expected benefit payments under the plan based on participant data and based on certain assumptions concerning mortality, retirement rates, termination rates, etc. The expected benefit payments for each year are then discounted back to the measurement date using the appropriate
Notes to Financial Statements - AES Ohio Table of Contents
spot rate for each half-year from the yield curve, thereby obtaining a present value of all expected future benefit payments using the yield curve. Finally, an equivalent single discount rate is determined which produces a present value equal to the present value determined using the full yield curve.
Consistent with the requirements of ASC 715, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans.
In future periods, differences in the actual return on pension plan assets and assumed return, or changes in the discount rate, will affect the timing of contributions, if any, to the plans.
The weighted average assumptions used to determine benefit obligations were:
Benefit Obligation Assumptions Pension
2024 2023 2022
Discount rate for obligations 5.66% 5.14% 5.41%
Rate of compensation increases 3.21% 3.21% 3.21%
Pension Plan Assets
Pension Plan assets are invested in multiple asset classes using a de-risking framework designed to manage the Pension Plan's funded status volatility and minimize future cash contributions. Investment strategies and asset allocations are intended to allocate additional assets to the fixed income asset class should the Pension Plan's funded status improve. Investment performance and asset allocation are measured and monitored on an ongoing basis.
Pension Plan assets are managed in a balanced portfolio comprised of two major components: return seeking assets and liability hedging assets. The expected role of plan return seeking assets is to provide additional return with associated higher levels of risk, while the role of liability hedging assets is to correlate the interest rate of the fixed income investments with that of the Pension Plans' liabilities.
Strategic asset allocation guidelines are determined by a Risk/Advisory Committee and approved by a Fiduciary Committee. These allocations consider the plan’s long-term objectives. The long-term target allocations for plan assets are 30% - 40% for return seeking assets and 60% - 70% for liability hedging assets. Return seeking assets include U.S. and international equity, while liability hedging assets include long-duration and high-yield bond funds and emerging market debt funds.
The investment approach is to move the Pension Plans to a more de-risked position, if and when the overall funded status of the Pension Plans improve, by periodically rebalancing the allocation of the Pension Plans' investments in growth assets and liability hedging assets in accordance with the committee's glide path. This strategy requires the daily monitoring of the Pension Plans' ratio of assets to liabilities in order to determine whether approved trigger points have been met, requiring the rebalancing of the assets.
All plan assets at December 31, 2024 are common collective trusts. With the exception of the cash and cash equivalents, the common collective trusts are valued using the net asset value method and are categorized as Level 2 in the fair value hierarchy. The underlying investments are mutual funds, common stock, or debt securities, in alignment with the target asset allocation.

Pension Funding
We generally fund pension plan benefits as accrued in accordance with the minimum funding requirements of ERISA and, in addition, make voluntary contributions from time to time. We contributed $7.5 million, $7.5 million and $7.5 million to the pension plan in the years ended December 31, 2024, 2023 and 2022.
We expect to make contributions of $0.2 million to our SERP in 2025 to cover benefit payments. We also expect to make contributions of $7.5 million to our pension plan during 2025.
Notes to Financial Statements - AES Ohio Table of Contents
Funding for the Pension Plans is based upon actuarially determined contributions that consider the amount deductible for income tax purposes and the minimum contribution required under ERISA, as amended by the Pension Protection Act of 2006, as well as targeted funding levels necessary to meet certain thresholds.
From an ERISA funding perspective, AES Ohio’s funded target liability percentage was estimated to be 95%. In addition, AES Ohio must also contribute the normal service cost earned by active participants during the plan year. The funding of normal cost is expected to be approximately $5.3 million in 2025, which includes $1.2 million for plan expenses. Each year thereafter, if the plan’s underfunding increases to more than the present value of the remaining annual installments, the excess is separately amortized over seven years. AES Ohio’s funding policy for the pension plans is to contribute annually no less than the minimum required by applicable law, and no more than the maximum amount that can be deducted for federal income tax purposes.
Benefit payments, which reflect future service, are expected to be paid as follows:
Estimated future benefit payments
$ in millions due within the following years: Pension
2025 $ 22.0
2026 22.0
2027 21.9
2028 21.8

2030 - 2034 106.1
8. SHAREHOLDER'S EQUITY
Common Stock
AES Ohio has 50,000,000 authorized common shares, of which 41,172,173 are outstanding at December 31, 2024. All common shares are held by AES Ohio’s parent, DPL.
Capital Contributions and Returns of Capital
During the years ended December 31, 2024 and 2023, AES Ohio received $200.0 million and $260.0 million, respectively, in equity contributions from DPL. The proceeds from these equity contributions allow AES Ohio to seek to improve its infrastructure and modernize its grid while maintaining liquidity. AES Ohio did not receive any equity contributions from DPL in 2022.
During the years ended December 31, 2024, 2023 and 2022, AES Ohio declared and paid distributions totaling $40.0 million, $83.0 million and $64.0 million, respectively.
9. CONTRACTUAL OBLIGATIONS, COMMERCIAL COMMITMENTS AND CONTINGENCIES

Purchased power commitments
AES Ohio enters into long-term contracts for purchased power through the SSO competitive bid auctions. In general, these contracts are subject to variable quantities and are terminable only in limited circumstances.
Purchase orders and other contractual obligations
At December 31, 2024, AES Ohio had various other contractual obligations including contracts to purchase goods and services with various terms and expiration dates. Due to uncertainty regarding the timing and payment of future obligations to the Service Company, and AES Ohio's ability to terminate such obligations upon 90 days' notice, we have excluded such amounts in the contractual obligations table above.
Notes to Financial Statements - AES Ohio Table of Contents
Contingencies
Legal Matters
In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under laws and regulations. We believe the amounts provided in our 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, including the matters discussed 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 as of December 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; 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; 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 the us and could require us to pay damages or make expenditures in amounts that could be material but could not be estimated as of December 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 December 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 December 31, 2024, AES Ohio could be responsible for the repayment of 4.9%, or $48.8 million, of $1.0 billion OVEC debt obligations if they came due, comprised of both fixed and variable rate securities with maturities from 2026 to 2040. OVEC could also seek additional contributions from AES Ohio to avoid a default in the event that other OVEC members defaulted on their respective OVEC obligations.
10. RELATED PARTY TRANSACTIONS
Service Company
The Service Company allocates the costs for services provided based on cost drivers designed to result in fair and equitable allocations. This includes ensuring that the regulated utilities served, including AES Ohio, are not subsidizing costs incurred for the benefit of other businesses.
Benefit Plans
DPL participates in an agreement with Health and Welfare Benefit Plans LLC, an affiliate of AES, to participate in a group benefits program, including but not limited to, health, dental, vision and life benefits. Health and Welfare Benefit Plans LLC administers the financial aspects of the group insurance program, receives all premium payments from the participating affiliates, and makes all vendor payments.

Long-term Compensation Plan
During 2024, 2023 and 2022, many of AES Ohio’s non-union employees received benefits under the AES Long-term Compensation Plan, a deferred compensation program. This type of plan is a common employee retention tool used in our industry. Benefits under this plan are granted in the form of performance units payable in cash and AES restricted stock units. Restricted stock units vest ratably over a three-year period. The performance units payable in cash vest at the end of the three-year performance period and are subject to certain AES performance criteria. Total deferred compensation expense for the years ended December 31, 2024, 2023 and 2022 was not material and is included in Operation and maintenance on AES Ohio’s Statements of Operations. The value of these benefits is being recognized over the 36-month vesting period and a portion is recorded as miscellaneous deferred credits with the remainder included in Other paid-in capital on AES Ohio’s Balance Sheets in accordance with ASC 718 - Compensation - Stock Compensation.
The following table provides a summary of our related party transactions:

Income Taxes
AES files federal and state income tax returns which consolidate DPL and its subsidiaries, including AES Ohio. Under a tax sharing agreement with DPL, AES Ohio is responsible for the income taxes associated with its own taxable income and records the provision for income taxes using a separate return method. Under this agreement, AES Ohio had a net receivable balance of $24.9 million and $24.4 million at December 31, 2024 and 2023, respectively, which are recorded in Taxes receivable on the accompanying Balance Sheets. During 2024, 2023 and 2022, AES Ohio made no payments to DPL for its share of income taxes.
11. BUSINESS SEGMENTS
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. The Chief Operating Decision Maker uses income / (loss) before income tax and net income / (loss) to allocate resources and capital in the annual budget and forecasting process, including making decisions on where to reinvest profits to support AES Ohio’s growth. On a monthly basis, the Chief Operating Decision Maker reviews variances in budget versus actual results and monitors changes in forecasted results to assess the underlying operating performance and analyze risks and opportunities for AES Ohio. See Note 1, "Overview and Summary of Significant Accounting Policies" for further information on AES Ohio.

12. 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 of promised goods or services 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.
Retail revenue
AES Ohio energy sales to utility customers are based on the reading of meters at the customer's location that occurs on a systematic basis throughout the month. AES Ohio sells electricity directly to end-users, such as homes and businesses, and bills customers directly. Performance obligations for retail revenue are satisfied over time as energy is delivered and the same method is used to measure progress, and thus the performance obligation meets the criteria to be considered a series. This includes both the promise to transfer energy and other distribution and/or transmission services.
In exchange for the exclusive right to sell or distribute electricity in our service area, AES Ohio is subject to rate regulation by federal and state regulators. This regulation sets the framework for the prices (“tariffs”) that AES Ohio is allowed to charge customers for electricity. Since tariffs are approved by the regulator, the price that AES Ohio has the right to bill corresponds directly with the value to the customer of AES Ohio's performance completed in each period. Therefore, revenue under these contracts is recognized using an output method measured by the MWhs delivered each month at the approved tariff.
In cases where a customer chooses to receive generation services from a CRES provider, the price for generation services is negotiated between the customer and the CRES provider, and AES Ohio only serves as a billing agent if requested by the CRES provider. As such, AES Ohio recognizes the consolidated billing arrangement with the CRES provider on a net basis, thereby recording no revenue for the generation component. Retail revenue from these customers would only be related to transmission and distribution charges.
Wholesale revenue
AES Ohio's share of the power produced at OVEC is sold to PJM and this revenue is classified as Wholesale revenue.
In PJM, the promise to sell energy as wholesale revenue is separately identifiable from participation in the Capacity Market and the two products can be transacted independently of one another. Therefore, wholesale revenue is a separate contract with a single performance obligation. Revenue is recorded based on the quantities (MWh) delivered in each hour during each month at the spot price, making the contract effectively “month-to-month”.
Notes to Financial Statements - AES Ohio Table of Contents
RTO ancillary revenue
Compensation for use of AES Ohio’s transmission assets and compensation for various ancillary services are classified as RTO ancillary revenue. As AES Ohio owns and operates transmission lines in southwest Ohio within PJM, demand charges collected from network customers by PJM are then allocated to the appropriate transmission owners (i.e. AES Ohio) and recognized as transmission revenue.
Transmission revenue has a single performance obligation, as transmission services represent a distinct service. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The price that AES Ohio, as the transmission operator, has the right to bill (received as a credit from PJM) corresponds directly with the value to the customer of performance completed in each period, as the price paid is the allocation of the tariff rate (as approved by the regulator) charged to network participants.
Capacity revenue
AES Ohio records its share of OVEC capacity revenue as Capacity revenue. The capacity price is set through a competitive auction process established by PJM. Depending on the availability and performance of the OVEC units, there may be additional performance bonuses or penalties, which would be recognized only if it becomes probable that such bonus or penalties will be incurred.
RTO capacity revenue has a single performance obligation, as capacity is a distinct good. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The capacity price is set through a competitive auction process established by PJM.

Notes to Financial Statements - AES Ohio Table of Contents
Payment terms for all receivables from contracts with customers are typically within 30 days.
We have elected to apply the optional disclosure exemptions under ASC 606. Therefore, we have no disclosures pertaining to revenue expected to be recognized in any future year related to remaining performance obligations, as we exclude contracts with an original length of one year or less, contracts for which we recognize revenue based on the amount we have the right to invoice for services performed, and variable consideration allocated entirely to a wholly unsatisfied performance obligation when the consideration relates specifically to our efforts to satisfy the performance obligation and depicts the amount to which we expect to be entitled for AES Ohio.

ITEM 9A. CONTROLS AND PROCEDURES
ITEM 9A. CONTROLS AND PROCEDURES
Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the CEO and CFO, as appropriate, to allow timely decisions regarding required disclosures.
We carried out the evaluation required by Rules 13a-15(b) and 15d-15(b), under the supervision and with the participation of our management, including the CEO and CFO, of the effectiveness of our “disclosure controls and procedures” (as defined in the Exchange Act Rules 13a-15(e) and 15d-15(e)). Based upon this evaluation, our CEO and CFO concluded that as of December 31, 2024, our disclosure controls and procedures were effective.
Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes those policies and procedures that:
•pertain to the maintenance of records that in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;
•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and
•provide reasonable assurance that unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements are prevented or detected timely.
Management, including our CEO and CFO, does not expect that our internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. In addition, any evaluation of the effectiveness of controls is subject to risks that those internal controls may become inadequate in future periods because of changes in business conditions, or that the degree of compliance with the policies or procedures deteriorates.
Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2024. In making this assessment, management used the criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in 2013. Based on this assessment, management believes that we maintained effective internal control over financial reporting as of December 31, 2024.
Changes in Internal Control Over Financial Reporting
We periodically review our internal controls over financial reporting as part of our efforts to ensure compliance with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002. In addition, we routinely review our system of internal controls over financial reporting to identify potential changes to our processes and systems that may improve controls and increase efficiency, while ensuring that we maintain an effective internal controls environment. During the fiscal quarter ended September 30, 2024, we implemented SAP IS-U, a software solution that SAP developed for businesses operating in the utility industries, which involved changes to related processes that are part of our system of internal controls over financial reporting and require testing for effectiveness. During the fiscal quarter ended December 31, 2024, we continued to evaluate and augment our existing controls to appropriately manage the risks inherent associated with this software implementation.
Other than the system and related process changes described above, there were no changes in our internal control
over financial reporting during the fiscal quarter ended December 31, 2024 that have materially affected, or are
reasonably likely to materially affect, our internal control over financial reporting.

ITEM 14. PRINCIPAL ACCOUNTING FEES AND SERVICES
ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES
The Financial Audit Committee of AES pre-approves the audit and non-audit services provided by the independent auditors for itself and its subsidiaries, including DPL and its subsidiaries and AES Ohio. The AES Financial Audit Committee maintained its policy established in 2002 within which to judge if the independent auditor may be eligible to provide certain services outside of its main role as outside auditor. Services within the established framework include audit and related services and certain tax services. Services outside of the framework require AES Financial Audit Committee approval prior to the performance of the service. The Sarbanes-Oxley Act of 2002 addresses auditor independence and this framework is consistent with the provisions of the Act. No services performed by the independent auditor with respect to DPL and AES Ohio and its subsidiaries were approved after the fact by the AES Financial Audit Committee other than those that were considered to be de minimis and approved in accordance with Regulation 2-01(c)(7)(i)(C) to Regulation S-X of the Exchange Act.
In addition to the pre-approval policies of the AES Financial Audit Committee, the DPL and AES Ohio Boards of Directors will specifically approve the annual audit services and fees of the independent auditor and the taking of other related actions, such as entering into the terms of the engagement letter.
Audit fees are fees billed or expected to be billed by our principal accountant for professional services for the audit of the Financial Statements, included in this Annual Report on Form 10-K and review of financial statements included in DPL's and AES Ohio's quarterly reports on Form 10-Q, services that are normally provided by our principal accountants in connection with statutory, regulatory or other filings or engagements or any other service performed to comply with generally accepted auditing standards and include comfort and consent letters in connection with SEC filings and financing transactions.
