HELSINKI, Finland -- Microsoft Corp. is buying Nokia Corp.'s lineup of smartphones and a portfolio of patents and services in an attempt to strengthen its fight with Apple Inc. and Google Inc. and capture a slice of the lucrative mobile computing market.
The US$7.2-billion (5.44 billion euros) deal announced late Monday marks a major step in the company's push to transform itself from a software maker focused on desktop and laptop computers into a more versatile and nimble company that delivers services on any kind of Internet-connected gadget.
"It's a bold step into the future -- a win-win for employees, shareholders and consumers of both companies," Microsoft CEO Steven Ballmer told reporters at Nokia's headquarters in Finland Tuesday. "It's a signature event."
The acquisition is being made at the same time that Microsoft is looking for a new leader. Just 10 days ago, Ballmer, 57, announced he would step down as CEO within the next year.
Stephen Elop, a Canadian who left Microsoft in 2010 to become Nokia CEO, will step down as president and CEO of the company to become executive vice-president of Nokia devices and services and will rejoin Microsoft once the acquisition closes.
The deal has fuelled speculation that Elop, a graduate of McMaster University in Hamilton, Ont., and a former Microsoft executive, will emerge as a top candidate to succeed Ballmer.
Microsoft, based in Redmond, Wash., has been racing to catch up with customers who are increasingly pursuing their digital lives on smartphones and tablet computers rather than traditional PCs.
The shift is weakening Microsoft, which has dominated the PC software market for the past 30 years, and empowering Apple, the maker of the trend-setting iPhone and iPad, and Google, which gives away the world's most popular mobile operating system, Android.
Microsoft is now betting it will have a better chance of narrowing the gap with its rivals if it seizes complete control over how the mobile devices work with its Windows software.
Investors in Nokia welcomed the deal, sending shares in the company up more than 35 per cent to 4.03 euros in Helsinki. Microsoft's shares, however, were down 4.4 per cent at $31.93 in early trading in the U.S.
Speaking to investors and analysts Tuesday, Ballmer admitted that the company has to play catch-up with the likes of Apple and Android.
"We know we need to accelerate. We're not confused about that," he said.
"We need to be a company that provides a family of devices."
Nokia, based in Espoo, near the Finnish capital, and Microsoft have been trying to make inroads in the smartphone market as part of a partnership forged in 2011. Under the alliance, Nokia's Lumia smartphones have run on Microsoft's Windows software, but those devices haven't managed to compete with iPhone or the array of Android-powered devices spearheaded by Samsung Electronics' smartphones and tablets
Terry Myerson, Microsoft Executive Vice-President of Operating Systems, admitted to a call to investors Tuesday that the message about company's products hasn't been getting through to consumers and that "marketing approaches we've used in the past have been inefficient."
Nokia board chairman Risto Siilasmaa told reporters that they had been preparing the deal since February.
"It's been an extremely pragmatic and deeply analytical process where we have left no stone unturned to understand all the possible alternatives for the company going forward," said Siilasmaa, who will be Nokia's interim CEO.
Microsoft hopes to complete the deal early next year. If that timetable pans out, about 32,000 Nokia employees will transfer to Microsoft, which currently has about 99,000 workers.
The proposed price consists of 3.79 billion euros ($5 billion) for the Nokia unit that makes mobile phones, including its line of Lumia smartphones that run Windows Phone software. Another 1.65 billion euros ($2.2 billion) will be paid for a 10-year license to use Nokia's patents, with the option to extend it indefinitely. Ballmer said that Microsoft will invest more than $250 million in a new data centre to serve European consumers.
Nokia CFO Timo Ihamuotila said the company's future will centre on its mobile networks business and two smaller units -- HERE mapping services and the advanced technologies unit including Nokia's licensing business.
"Our aim is clearly to grow the networks business in a profitable way," he said in a call to investors. "It is a cash-generating business where we can invest into the future growth."
Nokia will continue to own the rights to its brand, but the deal between the two companies prevents it from venturing into a separate smartphone business until the end of 2015.
Neil Mawston from Strategy Analytics said the move was good for Nokia's shareholders but did not change much for the ailing Finnish firm which has lost significant market share.
"Nokia is still heavily dependent on Microsoft's software capabilities and Microsoft continues to lag the market like it has done in the last few years," Mawston said. "Not much will change whether Nokia is inside or outside the Microsoft portfolio."
The deal with Nokia represents the second most expensive acquisition in Microsoft's 38-year history, ranking behind an $8.5 billion purchase of Internet calling and video conferencing service Skype. Tony Bates, who ran Skype, is also regarded as a potential successor to Ballmer.
The money to buy Nokia's smartphones and patents will be drawn from the nearly $70 billion that Microsoft held in overseas accounts as of June 30.
