Ratios
From the filings
At the close of 21 September 2026
Every figure is arithmetic on the filed lines (hover a name for the formula); the priced ones use the latest daily close, CBOE delayed quotes, daily history, by CBOE, for splits. Debt to equity here stands on the one borrowings figure Southern Co. files, which has finance leases inside it; operating leases are a separate line. Nothing here is a valuation or a view.
Price, 17 September 2021 to 21 September 2026
Daily closes from CBOE delayed quotes, daily history, by CBOE, for splits; the last is 21 September 2026. P/E is the close over the trailing four quarters' EPS as filed at each filing date, on the current share count; the dashed line is the median over the range shown. Sales and margin are quarterly revenue and the operating margin from the tables above. EV/EBITDA, price to book and market cap to sales use the latest filed balance sheet and share count at each date. Drawn in your browser; the range and overlay you pick are remembered here only.

* The fourth quarter is the full year less the first three quarters, because the company files the year and not the quarter on its own. Money is in $ million as the company files it, or in $ billion by the switch above the tables; per share figures and the share count are as they are. Free cash flow is operating cash flow less capital expenditure; the effective tax rate is income tax over pre-tax income; margins are the line over revenue. Gross profit is revenue less cost of revenue, and operating income is revenue less the company's own total costs, where the statement does not print those lines. Cash flow lines filed year to date are the difference between two filings. Shares outstanding are at the period end where the balance sheet tags them, otherwise the count on the filing's cover page. A derived fourth-quarter EPS is left blank when a split in the year makes the arithmetic meaningless.

Income statement lines from each year's 10-K, the year linked to its filing; TTM is the sum of the last four quarters. Free cash flow is operating cash flow less capital expenditure; the effective tax rate is income tax over pre-tax income; margins are the line over revenue. Gross profit is revenue less cost of revenue, and operating income is revenue less the company's own total costs, where the statement does not print those lines. Those four are arithmetic on the filed numbers; everything else is as filed. Money is in $ million as the company files it, or in $ billion by the switch above the tables; per share figures and share counts are as they are. † The year as the company last restated it in a later filing; rest on a figure for the one first filed. EPS is as filed.

Buybacks and dividends are the cash paid in the year, from the cash flow statement; the dividend per share is as declared. Diluted shares are the weighted average for the year; a falling count is the buybacks net of issuance. TTM sums the last four quarters; the share counts are the latest quarter's.

Compounded growth is the latest fiscal year over the year that many years earlier, annualised; the TTM column is the last four quarters over the four before. Return on equity is net income over shareholders' equity at each year end, averaged over the window (the TTM column is the latest year alone); equity is the parent's shareholders' equity as tagged in the 10-K. Arithmetic on filed numbers, nothing forecast.
