Shares Outstanding
Shares outstanding is the count of shares that divide company-level numbers into per-share numbers.
Market cap, EPS, and dividends per share all depend on the share count. A falling count means buybacks are retiring equity. A rising count means issuance, acquisitions paid in stock, or employees exercising options. The direction of the count is a capital-allocation fact, not a footnote.
Use the diluted count for valuation. Basic shares understate the claims on future earnings. When you see EPS rising and share count rising too, check that total profit is rising faster. Otherwise the per-share story is being diluted even as the headline grows.
Formula
Diluted shares outstanding = common shares + dilutive options, warrants, and convertibles
Live example
Apple Inc. (AAPL) last printed at $345.65 with a market cap of $5.04T. Market cap is the equity value you see above. Enterprise value would add net debt, which this quote row does not itemize.

Questions
What is a share split's effect?
The count changes and the price changes in proportion. Market cap should not change because of the split itself.
Where is the count on Stocklytics?
It is embedded in market cap (price × shares) and in EPS. A large gap between price move and market-cap move is the clue that the count changed.
