Risk factors and legal proceedings

The risks DAYTON POWER & LIGHT CO names in Item 1A of its 10-K filed Mar 2, 2026: 27 risks under these headings, as written.4

  • RISKS ASSOCIATED WITH OUR OPERATIONS
  • Our business is sensitive to weather and seasonal variations.
  • Our transmission and distribution system is subject to operational, reliability, capacity and development risks.
  • Our membership in an RTO presents risks that could 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.
  • Severe weather or catastrophic events could adversely affect our facilities, systems and operations.
  • 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.
  • 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.
  • 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 may be negatively affected by a lack of growth or a decline in the number of customers.
  • Highly infectious or contagious disease outbreaks could impact our business and operations.
  • 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.
The other 16 risks
  • 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.
  • We are subject to collective bargaining agreements that could adversely affect our business, 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.
  • Cyber-attacks and data security breaches could harm our business.
  • 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.
  • 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.
  • Our increased costs due to renewable energy requirements may not be fully recoverable in the future.
  • 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.
  • 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.
  • 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.
  • 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.
  • Concerns about data privacy have led to increased regulation in certain markets and other actions that could impact our businesses.
  • Tax legislation initiatives or challenges to our tax positions could adversely affect our operations and financial condition.
  • 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.
  • 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.
  • Our ownership by AES subjects us to potential risks that are beyond our control.

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 9. Contractual Obligations, Commercial Commitments and Contingencies included in Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K.

The following additional information is incorporated by reference into this Item: information about the legal proceedings contained in Regulation And Market Structure and Environmental Matters in Item 1. Business of this Annual Report on Form 10-K.
