Meta celebrated its 20th anniversary this week as all good and mature businesses should: by paying shareholders a dividend. In lieu of a birthday bash, the Silicon Valley stalwart marked its coming of age with a stock buy-back and, for the first time, by offering a dividend. Investors will receive 50 cents per share. Markets partied, with Meta’s share price rising by 20%, adding more than $200bn to the company’s market capitalisation on the day of the announcement.
