Chegg  (CHGG) - Get Report shares jumped after the education-technology company beat analysts' adjusted-earnings estimates and won a vote of confidence from a top industry tracker.

The stock of the Santa Clara, Calif., company at last check surged 28% to $56.21 after the provider of online tutoring services and textbook rentals, among other student services, reported first-quarter adjusted earnings of 22 cents a share.

On a GAAP basis, Chegg reported that its net loss widened to 5 cents a share from 4 cents. Shares outstanding rose 4.9% to 122.4 million.

Chegg reported quarterly revenue of $131.6 million, 6.5% higher than the estimate of analysts polled by Zacks, and 35% above the $97.4 million the company reported for the first quarter of 2019.

The number of subscribers at Chegg rose to 2.9 million at the end of the first quarter, a 35% increase over the first three months of 2019.

"We saw a substantial increase in new subscribers, both domestically and globally," Chief Executive Dan Rosensweig said in a statement.

Chegg also recorded 235 million content views during the first quarter of 2020.

For the second quarter Chegg is estimating revenue at $135 million to $137 million.

"While we are comfortable providing guidance for Q2, there are many unknowns, such as school start dates, enrollment trends, and whether schools will be taught on-campus, online or both," Chief Financial Officer Andy Brown said in a statement.

"As such, it is difficult to predict how much, if any of Chegg's first-half momentum will continue; therefore we believe it is premature to update our guidance for the second half of the year."

Shares of Chegg on Tuesday also got a boost from an upgrade by Raymond James, with analysts at the firm raising their rating on the educational tech firm to outperform from market perform.
