Fortune 100 companies are the 100 largest private and publicly held American companies based on gross revenue. Fortune magazine publishes the Fortune 100 list annually, along with the Fortune 500 and 1000 lists. Though the Fortune 100, 500, and 1000 list only American companies, many have significant international operations. While the Fortune 100 rankings are based on revenue, the list also provides each company's profit and margin numbers.
The Fortune 100 survey includes only companies that are incorporated in the United States and file financial statements with U.S. government agencies. The list includes private companies that file 10Ks with government agencies and mutual insurance companies that file financial statements with state regulators. Many of the companies on the Fortune 100 are owned by international entities but are included on the list because they file financial statements with the U.S. government. Private companies that do not file financial statements with U.S. government agencies are excluded.
The largest company on the Fortune 100 list for 2014 is Walmart with a gross revenue of over $46 billion. Walmart is followed by Exxon Mobil, Chevron, Berkshire Hathaway, Apple, Phillips 66, General Motors, Ford Motors, General Electric and Valero Energy. The Fortune 100 companies employ more than 5 million workers collectively.
