SAN FRANCISCO — Yahoo reported earnings Monday that were considerably above Wall Street expectations.
Yahoo reported net income in the fourth quarter of $272.3 million, or 23 cents a share, compared with $295.6 million, or 24 cents a share, in the period a year earlier.
But using a nonstandard accounting method favored by Wall Street analysts, the net income was 32 cents a share. Analysts had expected 28 cents a share, according to a survey by Thomson Reuters.
The company said revenue was up 1.6 percent from the quarter, to $1.35 billion.
“I’m proud of Yahoo’s 2012 and fourth-quarter results,” Yahoo’s chief executive, Marissa A. Mayer, said in a news release. “In 2012, Yahoo exhibited revenue growth for the first time in four years, with revenue up 2 percent year over year.”
Yahoo’s fourth-quarter earnings arrived at a critical juncture for Ms. Mayer, who joined the company six months ago.
Since then, her sheer presence at Yahoo headquarters seems to have jolted the company’s stock back to life. Shares are up 30 percent since July, and closed at $20.52 on Thursday, their highest price since September 2008.
Yahoo’s stock jumped more than 1 percent Monday in after-hours trading after closing at $20.31 in regular trading.
With Ms. Mayer’s honeymoon coming to an end, investors are eager to see whether she can deliver revenue growth.
Yahoo’s revenue has largely languished in an increasingly competitive landscape, in which it now finds itself vying with Facebook and Google for engineers, and for greater share of the online display advertising market.
The company’s search business, which Yahoo outsourced to Microsoft in 2009, is on its last legs, propped up only because of a revenue-guarantee clause in its contract with Microsoft that is set to expire in two months, though search revenue rose 4 percent in the fourth quarter, to $482 million compared with $465 million for the year-ago quarter.
But as Ms. Mayer has acknowledged, Yahoo’s future growth may well depend on its mobile strategy. Without mobile hardware, a browser or a social platform of its own, Yahoo has a long way to go.
In the past, Ms. Mayer has said the company’s mobile growth may come from smaller-scale acquisitions of mobile app companies. Yahoo acquired Stamped, a mobile app, for an undisclosed sum in October.
In December, Yahoo acquired OnTheAir, a small videoconferencing start-up, whose five-member team will focus on mobile products. Last week, it made its third acquisition with Snip.it, a San Francisco start-up. Like Stamped and OnTheAir, the service was immediately shut down. The team said it would be working in the “social news” area.
