Shares of Twitter were absolutely slammed on Thursday, after a mixed earnings report on Wednesday that beat expectations but showed slowing user growth.
The stock ended trading down $15.92, or 24.13%, to $50.05 a share.
In the report, Twitter saw its average monthly active users (MAUs) grow 30% year to year to 241 million, while mobile MAUs increased 37% to 184 million. They represented 76% of the company's total MAUs.
"Despite high brand awareness, high visibility in media channels, and increased publicity around its IPO in November, Twitter’s user growth was muted and we remain concerned about the continued deceleration in MAU growth," JP Morgan analyst Doug Anmuth wrote in a note.
"Twitter maintains some of the industry’s strictest limits on ad load in order to optimize for user experience, and the company is launching several initiatives through 2014 to accelerate user growth and improve user retention. These include simpler on-boarding processes with a native mobile sign up and messages to reengage inactive users."
Still, Anmuth also raised his price target on the stock from $40 to $44.
"We recognize that it is still early in potential user growth, and certainly in ad monetization and product innovations, but the challenges around user metrics in 4Q are likely to raise more questions around whether Twitter can become a truly mainstream product. We think overall engagement concerns are likely to overshadow monetization strength in the near term," he wrote.
Twitter CEO Dick Costolo addressed the issue of user growth in a conference call on Wednesday afternoon.
"With confidence in our ability to scale revenue, we are doubling down in 2014 to accelerate the growth of our core user base," he said.
"One of our core values as a company is to reach every person on the planet, and in 2014 we're focused on building a Twitter that is truly accessible and valuable to everyone."

It also posted a net loss of $511 million the company, which is more than double its quarterly revenue. The company saw a net loss of $9 million in the same period last year.
