Workplace messaging platform Slack reported fiscal first-quarter results and guidance that topped estimates, but signs of lowing user additions raised concerns about whether the pandemic-led boost to demand was sustainable.
Slack Technologies (NYSE:WORK) was down 12% in postmarket trade.
The company guided second-quarter losses within a range of $0.04-to-$0.03 a share, above Wall Street estimates for a loss of $0.06. Revenue guidance of $206-to-$209 million topped estimates of $200 million.
For fiscal 2021, Slack expects revenue of between $855 million to $870 million, with losses between 19 cents and 17 cents a share.
The company said it added 12,000 net new paid customers in the quarter, suggesting a slowdown in the pace of net adds for the month of April.
Slack previously reported net adds of 13,000 for the first three months of the year.
