Snap Inc shares plunged in after-hours trading on Wednesday after the parent of the popular disappearing-messaging app Snapchat reported slowing user growth and revenue that fell short of analyst estimates amid stiff competition from Facebook.
Shares of the company (snap) fell more than 24% to $17.39 after the first quarterly earnings report since Snap’s red-hot initial public offering in March.
Snap said its daily active users (DAUs) rose 36.1% to 166 million in the first quarter from a year earlier, down from the 47.7% rise in users for the fourth quarter and 62.8% jump for the third quarter that the company had reported in its IPO filing.
J.P. Morgan expected Snap’s DAUs to grow to 169 million in the first quarter, while Monness, Crespi, Hardt & Co pegged DAUs at 173 million.
Still, the growth was faster than larger rival Facebook, which said its daily user base grew 18% year-over-year in the first quarter, as well as Twitter, which reported growth of 14% in daily active users from a year earlier.
