(Reuters) — Chipmaker Broadcom said on Thursday it will buy antivirus software maker Symantec’s enterprise security unit for $10.7 billion in cash to scale up its software business through deals.

Shares of Symantec rose 3.6% and Broadcom 2% in extended trading.

Broadcom last year bought U.S. business software maker CA for $18.9 billion and was reportedly in talks to buy infrastructure software company Tibco, which was taken private by Vista Equity Partners for $4.3 billion in 2014.

Its push to software came after a failed attempt last year to buy mobile chipmaker Qualcomm Inc for $117 billion, which was scuttled by the Trump administration, citing national security.

“M&A has played a central role in Broadcom’s growth strategy and this transaction represents the next logical step in our strategy,” Broadcom Chief Executive Officer Hock Tan said.

Through a string of acquisitions, Tan has propelled the chipmaker that was worth just a few billions to a market capitalization of about $108 billion in the 13 years that he has been at the helm.

Broadcom said the Symantec deal is expected to close in the first quarter of its fiscal year 2020 and is subject to regulatory approvals in the United States, European Union and Japan. It plans to raise fresh debt to fund the deal.

Symantec’s enterprise security unit offers a mix of security products and services to business and government customers, helping them improve their security, while reducing cost and complexity.

Revenue at the unit, which is being sold to Broadcom, rose 9.9% to $611 million. Analysts on average had expected $564.3 million.

Symantec has been struggling with severe competition from nimbler rivals and sources had told Reuters last month that it walked away from negotiations to sell the entire company to Broadcom over price disagreements.

Several of its top executives, including CEO Greg Clark, have left the company this year, while it is also being investigated by U.S. regulators over an accounting irregularity.

Symantec, which will be left with consumer focused Norton LifeLock business, said it would issue a special dividend of $12 per share in the fourth quarter and buyback an additional $1.1 billion worth of shares.

The company, which reported better-than-expected first-quarter results on Thursday, said it plans to cut the global workforce by about 7% and will take a charge of about $100 million. It employed more than 11,900 people as of March 29.
