Berkshire Hathaway

RANK6

Warren Buffett’s legendary company falls a couple of slots, to No. 6 on the Fortune 500—its lowest ranking since 2012—as companies like Amazon have steadily upstaged it. Berkshire’s revenues last year grew less than 3%, though its profits surged to record highs, thanks to huge (though unrealized) gains on Buffett’s stock investments (an accounting quirk that the famed investor himself gripes about). Meanwhile, the insurance conglomerate’s cash hoard continues to grow, surpassing $137 billion this year. Buffett has held off on using it to make more acquisitions, saying in early May at the company’s annual meeting, “We haven’t seen anything that attractive.”
