Twitter (NYSE: TWTR) reported Wednesday that the number of active users in the most recent quarter was flat compared to the previous quarter. That's the first time it hasn't seen sequential user growth since it went public in 2013.
The stock, which traded midday Thursday at $14.39 U.S., fell 59 cents, or 3.9%, following the company's release of its quarterly financial results.
The micro-blogger said it had an average of 320 million monthly active users in the fourth quarter, the same as in the previous quarter.
Excluding those who access Twitter through messaging platforms, it reported 305 million monthly active users, a decline of two million from the third quarter.
The company said it lost $90.2 million U.S., though revenues rose 48.3% to $710.5 million U.S. in the quarter ended Dec. 31, roughly in line with market expectations.
But its first-quarter revenue guidance came in below what analysts were forecasting.
Twitter co-founder Jack Dorsey returned as CEO last summer, promising to re-ignite growth in the social networking firm.
The stock has plunged almost 70%t in the last year as investors worry about the company's slowing growth in its user base. Its 52-week low was $14.31 U.S., in contrast to a 52-week high of $53.49 U.S.
