Imperva Inc. gained the most in three months after boosting its yearly sales outlook and reporting second-quarter revenue that beat analysts’ estimates.
Revenue of $53.5 million topped the $48.5 million average estimate of analysts polled by Bloomberg. The Redwood Shores, California-based data-security company also raised its annual sales forecast to a range of $215 million and $217 million, up from a previous forecast for as much as $207 million.
Imperva, which made three acquisitions in 2014, plans to continue growing by 31 percent this year, Chief Executive Officer Anthony Bettencourt said in a Bloomberg Television interview Friday.
In an interview in June, Bettencourt said the company has set its sights on winning larger contracts as big as $200 million, which are typically dominated by companies like International Business Machines Corp.
The shares rose 6.4 percent to close at $68.74 in New York after climbing as high as 13 percent earlier, their biggest increase since May 8.
