Non-GAAP Financial Matters Strategic & Financial Highlights - Published Feb. 26, 20253 This presentation contains references to certain financial measures including Baseline O&M, Core earnings per share (“Core EPS”) and Operating earnings per share (“Operating EPS”), as “non-GAAP financial measures,” which are not calculated in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) and exclude the impact of “special items,” from earnings attributable to FirstEnergy Corp. from continuing operations for Operating EPS. Core EPS further excludes from Operating EPS the earnings contribution of Signal Peak and net periodic pension and other post- employment benefits (“OPEB”) credits, other than the mark-to-market adjustment and other related charges, which are already excluded as special items. Core EPS and Operating EPS also exclude the impact of Discontinued Operations. Management uses these non-GAAP financial measures to evaluate the company’s and its segments’ performance and manage its operations and 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 Core EPS and Operating EPS, including by segment, 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, excluding the impacts described above, 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 and Core EPS is EPS attributable to FirstEnergy Corp. from Continuing Operations (GAAP), as reconciled. Also, such 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 and Core EPS are calculated based on the weighted average number of common shares outstanding in the respective period. A reconciliation of forward-looking non-GAAP measures, including 2025 Core EPS and Core EPS compound annual growth rate projections, to the most directly comparable GAAP measures is not provided because comparable GAAP measures are not 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 Core EPS guidance, or Core EPS growth rate projections 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.
