Forward-looking Information

Statements contained in this Annual Report concerning expectations, beliefs, plans, objectives, goals, strategies, future events or performance and underlying assumptions and other statements that are other than statements of historical fact are "forward-looking statements" within the meaning of the federal securities laws. Although the Registrants believe that the expectations and assumptions reflected in these statements are reasonable, there can be no assurance that these expectations will prove to be correct. Forward-looking statements are subject to many risks and uncertainties, and actual results may differ materially from the results discussed in forward-looking statements. In addition to the specific factors discussed in "Item 1A. Risk Factors" and in "Item 7. Combined Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Annual Report, the following are among the important factors that could cause actual results to differ materially and adversely from the forward-looking statements:

  • weather and other conditions affecting generation, transmission and distribution operations, operating costs and customer energy use;

  • strategic acquisitions, dispositions, joint-ventures or similar transactions and our ability to consummate these business transactions, integrate the acquired entities or realize expected benefits from them;

  • the outcome of rate cases or other cost recovery, revenue or regulatory proceedings;

  • catastrophic events such as epidemic or pandemic health events, wildfires, earthquakes, explosions, floods, droughts, tornadoes, hurricanes and other extreme weather-related events (including events potentially caused or exacerbated by climate change) and their impact on economic conditions, financial markets and supply chains;

  • capital market conditions, including the availability of capital, credit or insurance, changes in interest rates and certain economic indices, and decisions regarding capital structure;

  • volatility in or the impact of other changes in financial markets, commodity prices and economic conditions, including inflation;

  • the direct or indirect effects on PPL or its subsidiaries or business systems of cyber-based intrusion or the threat of cyberattacks;

  • development, adoption and use of artificial intelligence by us, our customers and our third-party vendors;

  • the effect of existing trade policies (including tariffs and other trade measures), the establishment of additional trade policies or subsequent changes to trade policies once announced or implemented, on the cost or availability of imported goods;
