Non-GAAP Financial Matters 3 Strategic & Financial Highlights - Published April 25, 2024 This presentation contains references to certain financial measures including Baseline O&M, Operating earnings (loss) and Operating earnings (loss) per share (“EPS”), including by segment and the impact of special items on the following measures: Total revenues, Total operating expenses, Total other expense, and Earnings (loss) attributable to FirstEnergy Corp. These are “non-GAAP financial measures” which are not calculated in accordance with U.S. Generally Accepted Accounting Principals, (“GAAP”). Management uses these non-GAAP financial measures to evaluate the Company’s and its segments’ performance and manage its operations, and frequently references these non-GAAP financial measures in its decision-making, using them to facilitate historical and ongoing performance comparisons. Management believes that the non-GAAP financial measures of Operating earnings (loss), Operating EPS, including by segment, and Baseline O&M, provide consistent and comparable measures of performance of its businesses on an ongoing basis. Management also believes that such measures are useful to shareholders and other interested parties to understand performance trends and evaluate the Company against its peer group by presenting period-over-period operating results without the effect of certain special items that may not be consistent or comparable across periods or across the Company’s peer group. These non-GAAP financial measures are intended to complement, and are not considered as alternatives to, the most directly comparable GAAP financial measures, which for Operating EPS is Continuing Operations EPS (GAAP), and for Baseline O&M is Other Operating Expenses, each as reconciled throughout the presentation. Also, the non-GAAP financial measures may not be comparable to similarly titled measures used by other entities. Special items represent charges incurred or benefits realized that management believes are not indicative of, or may obscure trends useful in evaluating the Company’s ongoing core activities and results of operations or otherwise warrant separate classification. Operating EPS is calculated by dividing Operating earnings (loss), which excludes special items, for the periods presented by the weighted average number of common shares outstanding in the respective period. Baseline O&M is calculated by excluding special items and other adjustments that are generally pass-through costs or recoverable under riders or other similar programs. A reconciliation of forward-looking non-GAAP measures, including 2024 Operating EPS, long-term annual Operating EPS growth projections and Baseline O&M forecasts, to the most directly comparable GAAP measures is not provided because comparable GAAP measures for such measures are not reasonably available without unreasonable efforts due to the inherent difficulty in forecasting and quantifying measures that would be necessary for such reconciliation. Specifically, management cannot, without unreasonable effort, predict the impact of these special items in the context of Operating EPS guidance, long-term annual Operating EPS growth rate projections and Baseline O&M forecasts because these items, which could be significant, are difficult to predict and may be highly variable. In addition, the Company believes such a reconciliation would imply a degree of precision and certainty that could be confusing to investors. These special items are uncertain, depend on various factors and may have a material impact on our future GAAP results.
