NEW YORK — Sprint Nextel has offered to buy out the minority shareholders of Clearwire for $2.1 billion in a deal that would give it total control of the company and also more space on the airwaves for data services.
Sprint said in a regulatory filing Thursday that it’s offering $2.90 per share for the 49 percent of the wireless network operator that it doesn’t already own.
Clearwire’s board hasn’t approved the sale, but said it’s in discussions with Sprint. In midday trading, Clearwire shares had jumped 15 percent to $3.16, suggesting that investors believe a better offer may be coming.
It’s been widely assumed that Sprint, the country’s No. 3 wireless carrier, would buy out Clearwire. Both companies have been pressed financially, but Sprint is getting an infusion of cash after selling 70 percent of itself to Softbank Corp. of Japan for $20 billion.
Clearwire, which is based in Kirkland, was formed by cellular pioneer Craig McCaw to take advantage of an emerging wireless technology, WiMax, which promised higher speeds and lower costs than conventional cellular technology.
Sprint was working on the same technology and in 2008 rolled those operations into Clearwire, gaining a stake of more than 50 percent.
Since then, it’s had a hot-and-cold relationship with Clearwire. Sprint uses Clearwire’s WiMax network to provide “Sprint 4G,” but the technology has been orphaned as other wireless carriers have opted for another fourth-generation technology called “LTE.” Sprint is now building out its own 4G LTE network, something that Clearwire would do as well if it had the funds.
Clearwire’s main asset is vast swaths of wireless spectrum, or space on the airwaves, that could be used to provide high data download speeds — a crucial competitive factor in today’s wireless industry.
