- No parent-only standalone financial statements exist (Constellation Energy Corporation is a U.S. GAAP holding company whose operating activities are conducted through its wholly owned subsidiary Constellation Energy Generation, LLC, and Form 10-K omits Schedule I), so no Consolidated − Standalone subtraction is performed. The only arithmetic shown in table cells is cumulative period splitting (Q4 = full year − 9M; Q2 = 6M − Q1; Q3 = 9M − 6M), displayed in italic with the formula.
