Southern Company
Statements
Segments
US companies must disclose in their mandatory reports how revenue breaks down across business segments, regions and product lines. We read that breakdown for you straight from the annual and quarterly reports (10-K and 10-Q) of Southern Company (SO). It shows which part of the business is growing — and which one is holding it back.
Remaining performance obligations
Remaining performance obligations are the part of the business already sold but not yet delivered and therefore not yet booked as revenue. In subscription and project businesses it points the way earlier than revenue does.
| As of | Remaining performance obligations |
|---|---|
| Q4 2018 | $487.0M |
| Q3 2018 | $168.0M |
| Q2 2018 | $263.0M |
| Q1 2018 | $458.0M |
Operating metrics
Operating metrics are the figures a company uses to measure its own business — customer counts, stores, deliveries or the churn rate. None of them appear in the financial statements, and they often explain earlier than revenue does why revenue is moving.
| Metric | Q2 2025 | Q3 2025 | Q1 2026 | Q2 2026 |
|---|---|---|---|---|
| Total generation (billion KWh) | – | 53.00B | 47.00B | 48.00B |

These metrics are not part of the financial statements; they sit in the narrative text of the filings. We read them out of the SEC filings using artificial intelligence and check every single figure against the original passage in the report; anything that is not found there verbatim is discarded.
