Though the results beat Wall Street's cautious expectations, they don't solve the company's broader problems.
Mr Dorsey added that the company was "confident about the road ahead", even as user monthly active user numbers were flat at 330 million in the quarter.
The company said it expected "to be GAAP-profitable for the full year 2018", referring to generally accepted accounting principles.
It's a hard won milestone for Twitter. And it has cut beloved but pricey projects like Vine, a video sharing service.
Twitter continued a push to diversify its sales beyond advertising. Twitter said that it made $91 million during Q4 2017 on $731.6 million of revenue, which is up 2 percent from a year ago.
In a letter to shareholders, Twitter chalked up the sales boost to "better-than-expected growth" in ad sales "across all major products and geographies".
There's no indication that Twitter benefited from changes to Facebook's algorithm, said Brian Wieser, an analyst from Pivotal Research who downgraded Twitter to a "sell" rating Thursday despite the strong quarter.
Profitability is an important achievement for Twitter, which has lost money consistently since its public offering, sparking speculation on whether it needed to sell itself to keep operating.
For many investors, the best hope is that Twitter will be acquired, but the stock's jump could make the company less attractive to potential suitors.

A year ago it unveiled a range of changes to attract new users which included products such as a live video streaming function for sports and news, and a doubling of the character limit for tweets to 280 in a bid to attract more advertisers. While it received some backlash from longtime users, Dorsey called it a success on Wednesday.
"We're seeing a lot more retweets and we're seeing a lot more mentions and we're also seeing people get more followers and return more often".
"We're not going to have to do any backfilling", Dorsey said. "We do believe that it is minimizing some of the complexities and some of the confusion around Twitter in general".
Twitter has also completed its roll out of 280 character tweets.
The profit came despite a fall in monthly users in the United States, where Twitter makes most of its revenue, to 68 million from 69 million in the third quarter. This is the second time in one year that the number of active U.S. users has dropped. It had 68 million users in the country in the fourth quarter, down from 69 million in the prior quarter. Total ad engagements were up 75% year-over-year which has been put down to engagement growth, improved products, better ad relevance to the user.
