NEW YORK (TheStreet) -- Though Twitter (TWTR - Get Report) managed to beat first-quarter estimates and show Wall Street it's more profitable than initially thought, none of that matters if the company can't do one major thing: grow its user base.
For the first quarter, Twitter posted breakeven results on $250.49 million in revenue, as advertising revenue surged 125% year over year to $226 million. The company said mobile advertising revenue was approximately 80% of total advertising revenue, while data licensing and other revenue totaled $24 million, a year-over-year increase of 76%. Analysts surveyed by Thomson Reuters were expecting Twitter to lose 3 cents a share on $241.47 million in revenue.
The company topped 255 million monthly active users (MAUs), but that was only an increase of 14 million from the previous quarter, its first as a public company. Though that number is up 25% year-over-year, growth is slowing. In the fourth quarter of 2013, MAUs grew 30.9% year over year.Some on Wall Street, including Goldman Sachs, were expecting much more. Analysts at Goldman Sachs were expecting around 265 million MAUs.

Advertising revenue per thousand timeline views reached $1.44 in the first quarter of 2014, a year-over-year increase of 96%. In an interview with Carl Quintanilla on CNBC, CEO Dick Costolo said Twitter was already a mainstream platform, and the company is working on three major initiatives, including simplifying the new user process to be much more mobile phone based, the recommendations sent, and the way Twitter organizes content for new users will drive growth. "The beauty of Twitter is that everyday, in countries around the world, Twitter is front and center, it's ubiquitous, in front of people, everyday," Costolo said during the interview. Shares were plunging in pre-market trading, falling 12% to $37.49. For the second quarter, Twitter expects revenue to be between $270 million and $280 million, with adjusted EBITDA between $25 million and $30 million.
