Revenue was up two percent from a year ago to a better- than-expected USD 732 million.
The number of monthly active users was 330 million, unchanged from the prior quarter but up four per cent from a year earlier.
While Twitter has built a solid core base of celebrities, politicians and journalists, it has failed to achieve the broader appeal of Facebook and other social platforms, hurting its ability to bring in ad revenues.
Twitter shares leapt 26 per cent to USD 33.86 in pre- market trade on the upbeat news.
The shares this month jumped above the 2013 offering price of USD 26 for the first time since late 2015.
The 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.
Chief executive Jack Dorsey welcomed "a strong finish to the year," and added "I'm proud of the steady progress we made in 2017, and confident in our path ahead."
The network has stepped up efforts to boost its user base and engagement, adding streaming video partnerships, doubling the character limit on tweets to 280 and making it easier to create "tweetstorms" by stringing messaging together.
Dorsey told a conference call that by relaxing the limits, "it minimizes some of the complexities" of using the platform and added, "more importantly it is enabling people to be more expressive about what's on their minds."
Jennifer Grygiel, a Syracuse University communications professor who follows social media, said the results are an important milestone for Twitter.
"It shows that Twitter has staying power," Grygiel said. "A lot of people have had doubts for several years."
Despite Twitter's problems these past few years, "it is unlike any other social media platform," Grygiel said.
"It really is the fastest newswire service we've ever seen," she said. "Influencers and news
junkies come to Twitter because of that microblogging function that we don't see in other places."
Earlier this month, BTIG Research analyst Richard Greenfield raised his outlook for Twitter, saying that "management has refocused the company on its core product (and) pushed their product team to iterate far faster than ever before in the company's history."
Greenfield said Twitter's use of artificial intelligence had "made the Twitter user experience more compelling by showing consumers the tweets they care most."
Twitter's monthly user base of 330 million is far behind the two billion of Facebook, but Twitter said its daily active user base -- for which it has not offered a specific number -- grew in double digits.
Both Twitter and Facebook have stepped up efforts to crack down on "bots" and other efforts to manipulate their platforms to deflect criticism from lawmakers and others concerned about the spread of disinformation.
"We are committed to making Twitter safer, and we are clarifying our policies, improving our enforcement, and communicating more clearly," the company said in a tweet.
