Share Count in a 10-Q: Finding Basic, Diluted and Current

A 10-Q reports the share count more than once, and the figures disagree for good reasons. Knowing which line is which tells you what to use for market cap, EPS and a value per share.

  1. Open the latest 10-Q on EDGAR and go to the main document
  2. Read shares outstanding for each class on the cover page and note the date
  3. Find weighted average basic and diluted shares beneath EPS on the income statement
  4. Check the equity statement and notes for issued, treasury and repurchased shares
  5. Note options and unvested awards from the stock compensation note
  6. Add every class together before using any count

Shares outstanding, by class, at a date after quarter end. That line is on the cover page of every 10-Q. It’s the freshest count in the filing, and it isn’t the only one. The income statement reports weighted average shares, basic and diluted, which are the figures EPS is divided by, while the statement of stockholders’ equity and the notes report shares issued, shares held in treasury, the quarter’s buybacks and the unvested awards that could turn into stock later. Each answers a different question. So they rarely agree, and a big buyback can pull them far apart.

The cover page: a count at a date

The SEC’s Form 10-Q has the company state how many shares of each class of its common stock were outstanding on the most recent date it could practicably report. In practice that’s shortly before filing. It falls after the balance sheet date, so a buyback or an award vesting in the weeks between shows up on the cover and nowhere in the quarter’s statements. Read the date as carefully as the number.

This is the count for anything measured today. Market cap uses it. So does a value per share.

Companies with more than one class list each on its own line. Add them. A cover showing 60 million Class A shares and 15 million Class B shares means 75 million shares in total, even if only Class A trades. Quote pages sometimes miss the unlisted class. Market cap then comes out short, a problem shares outstanding and dilution covers in more detail.

The income statement: weighted averages

Go to the bottom of the income statement. Below net income sit basic and diluted EPS. Just beneath them are the weighted average shares used for each.

Basic weighted average shares spread the share count across the quarter by time. A share outstanding all quarter counts once. One bought back halfway through counts for half.

Diluted shares add the stock that options, RSUs and convertibles would create. Options and RSUs go through the treasury stock method, which assumes the company uses the cash from exercise to buy back shares at the period’s average price, so only the net increase lands in the count. Convertible debt is assumed converted. The interest it would no longer cost goes back into earnings. Anything that would raise EPS is left out as antidilutive, and the EPS note often lists those excluded securities, which is a quick way to see how much potential stock sits just out of the money.

Watch the columns. Later 10-Qs in the fiscal year show two periods side by side. One column covers the three months just ended and the other the year to date, each with its own weighted average, and the year-to-date figure can differ sharply from the quarter’s when a buyback or an offering happened in an earlier quarter. The earnings per share page works through the division.

The equity statement and the notes

The balance sheet gives shares issued and treasury shares. They’re usually in parentheses beside the equity lines. Subtract treasury from issued. That should land on the quarter-end count.

The statement of stockholders’ equity shows how the count moved during the quarter, with shares issued for stock awards, shares repurchased and shares retired, and the equity note describes the buyback program behind those repurchases, including how much of the authorization is left. Later in the filing, a quarter with buybacks usually comes with a table of the company’s own repurchases broken out by month, with shares bought and the average price paid.

Then find the stock-based compensation note. It lists options outstanding with their exercise prices. Unvested RSUs are there too. Those are the raw material for a fully diluted count.

A quarter with a buyback in the middle

Company B starts a 90-day quarter with 100 million shares outstanding. On day 60 it buys back 9 million shares in one block. That leaves 91 million outstanding for the last 30 days. Before the cover-page date it buys back another 1 million. Options and RSUs add a net 2 million shares under the treasury stock method. Net income for the quarter is $48.5 million.

No two of these counts match. The quarter opened at 100 million and the cover says 90 million, while the weighted average of 97 million falls between them because the big repurchase came late, with only a third of the quarter left to run.

Multiply the weighted average by the share price for market cap. You’d be counting 7 million shares that no longer exist. That’s about 7.8% too many, since 97 ÷ 90 is roughly 1.078. Use the cover figure.

Pulling each number on EDGAR

Search EDGAR for the company. Filter its filings by form type to show only 10-Qs. Finding 10-Q and 8-K filings covers the search and the filters. Open the latest one and choose the main document, the one listed first in the filing index, which holds the cover page, the statements and the notes together.

From there, your browser’s find function does most of the work. Search for “outstanding” to reach the cover page. Search “weighted” to land on the income statement and the EPS note. “Treasury” and “repurchase” find the balance sheet, the equity statement and the monthly buyback table. Try “restricted stock” or “options outstanding” for the compensation note.

Write each figure down with its date or period beside it. Then sort out which goes where. The cover count goes into market cap. The weighted averages are already in EPS. For a fair value per share, take the cover count and add the dilutive options and awards from the notes, which is the denominator estimating fair value with a DCF asks for. Quote pages label these counts loosely. Share count vs shares outstanding sorts out which is which.

What goes wrong

  • Reading the year-to-date column when you wanted the quarter.
  • Treating shares issued as outstanding. Issued includes treasury stock.
  • Counting only the listed class when the cover shows more than one.
  • Dividing a DCF equity value by weighted average basic shares, which is wrong twice over, since it leaves out options and awards and, being an average, still lags any buyback or offering that happened during the quarter.

Related questions

Does a 10-K show the share count the same way?

Largely, yes. The 10-K cover page also gives shares outstanding by class as of a recent date, and the income statement gives weighted average basic and diluted shares for the full year. The 10-K cover adds the market value of shares held by non-affiliates, measured at an earlier date, which is a different figure from the count.

Why would diluted shares equal basic shares?

Either the company has no options, awards or convertibles that would add shares, or it lost money in the period. In a loss period, adding shares would make the loss per share smaller, so accounting rules leave them out and the two counts match.

Why doesn't the quote page match the 10-Q cover?

Tools refresh the count at different times and from different sources. Some show the weighted average, some show only the listed share class, and some lag a recent filing. The tool's glossary of field definitions should say which count it uses.
