July 29 (Reuters) - Canada's business software maker Open Text Corp raised its fiscal 2016 operating margin forecast and reported a better-than-expected revenue for the first time in four quarters as it closed more big contracts.
The company also said it would buy back up to $200 million of stock and reaffirmed its intent to spend $3 billion on acquisitions.
Open Text's U.S.-listed shares rose 14 percent in trading after the bell on Wednesday as the financial results overshadowed the possibility of a higher U.S. tax bill.
The company, whose software to help companies manage documents and workflows, has been struggling with slowing revenue growth as it focuses on building its cloud business.
"With a more directly aligned sales leadership team in place, our sales organization performed extremely well in Q4, closing 26 deals over $1 million (11 cloud and 15 license)," Chief Executive Mark Barrenechea said.
The company raised its fiscal 2016 non-GAAP operating margin model forecast to 30-34 percent from 28-30 percent. Margins were 30.9 percent in fiscal 2015.
"I don't think it's just the numbers that is helping the stock after market, I think it's also the operating margin guidance that company is putting out there for next year," Benchmark Company analyst Mark Schappel said.
Open Text said the U.S. Internal Revenue Service had issued a draft "notice of proposed adjustment" in connection with the company's reorganization five years ago, proposing a one-time increase of $280 million in U.S. federal taxes.
