Estimate market capitalization from share price and shares outstanding.

Result

$5,343,750,000

Estimated market capitalization based on current share price multiplied by shares outstanding.

Market capitalization$5,343,750,000

Share price used$42.75

Shares outstanding used125,000,000

Value per million shares$42,750,000

$42.75 per share across 125,000,000 shares outstanding produces a market capitalization near $5,343,750,000.
This estimate works best when the share count and price come from the same period and the same share basis.
Use the result as a quick market-value snapshot only, because diluted share counts and fast price moves can change the number.

This is a simple market-value estimate, not investment advice. Real market capitalization also depends on which share-count basis is used and when the price snapshot is taken.
