Southern Company vs the Utilities sector and the S&P 500

Southern Company's latest reported figures next to the median of the other 30 S&P 500 Utilities companies and of the other 502 S&P 500 companies; each median is taken over the companies with a comparable figure (counts in the footnote). A median is the middle value, not an average, so one very large company does not move it.

Southern Company: fiscal year ended December 2025, from its 10-K and 10-Q filings with the SEC. Medians computed October 20, 2026 from each company's latest annual filing (fiscal years ending between July 2025 and September 2026) and our price archive. Prices for every company, Southern Company included, are the last regular-session prices of October 19, 2026; the 1-year change compares that price with each company's last close on or before October 20, 2025. Net margin and price change are our calculations from reported figures. Each median counts only the companies with a comparable figure (sector / S&P 500): revenue growth 30/496, net margin 30/496, dividend per share 28/349, 1-year price change 30/490; the reasons below can overlap. 12 are left out of the price figure because our archive holds no comparable close for them; dividend medians are among the 28 sector and 349 S&P 500 companies reporting a per-share dividend. The S&P 500 price figure is the middle company's change, not the index's return.
