Utilities
Regulated revenue and capital-heavy operations: Reported FY2025 Results
Duke Energy and Southern Company provide annual utility observations with identifiable reported and adjusted measures. This source-linked study separates reported observations from interpretation and compares only the selected issuers.
The business models
Duke Energy and Southern Company provide annual utility observations with identifiable reported and adjusted measures. Regulated revenue and asset investment need to be considered alongside depreciation, financing expense and any one-time adjustments.
Selected reported observations
Duke Energy Corporation (DUK), year ended 2025-12-31 — Operating revenues: 32,237 USD million; Regulated electric revenues: 29,060 USD million; Regulated natural gas revenues: 2,870 USD million. The Southern Company (SO), year ended 2025-12-31 — Operating revenues: 29,600 USD million (rounded from USD 29.6 billion); Net income as reported: 4,341 USD million; Reported EPS: 3.94 USD/share.
Analytical interpretation
Confirm the legal reporting entity in combined filings. Compare parent consolidated statements with parent statements and identify the reconciliation whenever using an adjusted result. The combined annual filing includes consolidated statements for the parent and several utility subsidiaries. The first number found by a text search may belong to a different registrant. Matching the heading, entity name and period is essential before comparing a revenue or debt balance with another utility. Annual reported earnings declined while the adjusted per-share comparison moved differently. This makes the reconciliation material rather than optional reading. Revenue growth cannot resolve the difference on its own; exclusions, share counts and expense changes should be examined separately.
Comparison boundaries
Rate mechanisms, weather, fuel recovery, financing and project timing differ by service territory. Revenue growth is not a direct measure of growth in earnings available to common shareholders.
Sources and method
Figures are selected historical annual observations from the linked company reports. Fiscal 2025 means the issuer’s own fiscal label, not a common calendar interval. Dollar amounts retain the million-dollar source unit, and source-rounded figures remain marked as rounded. The analysis is editorial interpretation; it is not company guidance, a sector return estimate or an investment recommendation. Source review date: 2026-11-15.
