Although Twitter posted revenue of $710.5 million (PDF) in the fourth quarter of 2015—a result that narrowly surpassed the company’s high-bar projection from the previous quarter—the social media company posted a net loss of $90 million for the fourth quarter.

Worse, however, were the company’s user base statistics. Twitter reported that its Monthly Average Users (MAU) essentially remained flat from Q3 to Q4, but if Twitter subtracted its SMS-only customers (who are largely based in India and Brazil and don’t see ads the way mobile customers do), that MAU number fell to 305 million per year, down from 307 in the previous quarter.

Twitter executives were quick to point out, however, that the monthly active user base had increased in January to Q3 levels. On the call, a Twitter executive attributed the rebound to the first quarter being a historically strong quarter for Twitter given the number of live events like award shows, sporting events, and other big celebrations that fall in that time period.

The company also noted that it tried to reduce the number of e-mails that it sent dormant users, something that may have contributed to the fall in MAUs.

In a shareholder letter, the company pointed out that it spent the last six months reorganizing—former CEO Jack Dorsey returned to his position recently as the company faltered financially. On the call, Dorsey said that in 2016 Twitter's objectives would be to "refine Twitter’s core services," invest in live streaming video, help content creators use Twitter more effectively, make Twitter safer, and help developers use Twitter to grow their businesses.

Twitter has struggled to find itself since its Initial Public Offering, and some have attributed that to poor feature rollout (like Moments, which Twitter’s executives reaffirmed their belief in on Wednesday's call) or increased ad saturation turning casual users off (Twitter executives assured investors that they still had headroom to add even more ads to the social media platform). Dorsey said on today’s call that Twitter would be making Periscope a primary source of investment funds, and he said that Twitter’s proposed new algorithmically out of order timeline layout would quickly make sense to users.

Dorsey’s pledge to “make Twitter safer” also hints at an issue that has dogged Twitter in recent years—how the company deals with abuse and trolls and how it deals with tweets from extremist groups like ISIS. Just recently, the company said that it removed 125,000 Twitter accounts from people who allegedly belonged to extremist organizations.

Although Twitter’s shares were up by four percent at close of market, the company lost three percent in after hours trading.
