The most directly comparable GAAP measure for adjusted diluted EPS is reported diluted EPS from continuing operations attributable to Duke Energy Corporation common shareholders, which includes the impact of special items (including costs-to-achieve the merger) and the mark-to-market impacts of economic hedges in the Commercial Portfolio segment. On a reported diluted EPS basis, this transaction is not anticipated to be accretive due to the level of costs-to-achieve the merger. Due to the forward-looking nature of this non-GAAP financial measure for future periods, information to reconcile it to the most directly comparable GAAP financial measure is not available at this time, as management is unable to project special items or mark-to-market adjustments for future periods.
