In a statement Wednesday, the CEO of Softbank and chairman of Sprint said the company's focus had shifted away from acquisitions, though he didn't address the Sprint deal specifically.
"While we continue to believe industry consolidation will enhance competitiveness and benefit customers, our focus moving forward will be on making Sprint the most successful carrier," Masayoshi Son said.
Part of Son's desire to buy T-Mobile probably lay in his desire to bring T-Mobile CEO John Legere into his team. The foul-mouthed, jeans-wearing Legere has upended long-standing industry practices and brought customers streaming back to T-Mobile, though he has no profits to show for his efforts.
With the T-Mobile deal now scotched, Son had to look elsewhere for iconoclastic leadership, said analyst Roger Entner of Recon Analytics.
"Son is looking for a more entrepreneurial spirit ... he's looking for someone willing to break the rules," Entner said.
In his own statement, Claure suggested Sprint would be taking on Verizon and AT&T through price cuts.
"We will focus on becoming extremely cost efficient and competing aggressively in the marketplace. While consolidating makes sense in the long-term, for now, we will focus on growing and repositioning Sprint," he said.
Claure, the son of a Bolivian diplomat who moved to the U.S. in the 1990s, built Brightstar into the world's largest distributor of cellphones, initially by exporting phones to Latin America. He then convinced U.S. cellphone carriers that they're better off outsourcing that side of the business.
Softbank will be acquiring his stake in the company, it said.
The chairman of the Federal Communications Commission, Tom Wheeler, welcomed news of Sprint dropping its T-Mobile bid.
"Four national wireless providers is good for American consumers. Sprint now has an opportunity to focus their efforts on robust competition," he said in a statement.
Hesse joined Overland Park, Kansas-based Sprint as CEO in 2007. It has lost money every year since then because of stiff competition and the disastrous legacy of the 2005 Nextel acquisition, but Hesse has been credited with improving the carrier's customer service and shepherding it back to the cusp of profitability. The soft-spoken Hesse was also the company's chief pitchman, appearing in its TV commercials for several years.
Recently, however, Sprint has become bogged down in a network upgrade. Its wireless broadband capabilities are well behind of competitors, and it has to invest massively to catch up. That's causing continuing losses, likely contributing to Hesse's replacement, according to analyst Greg Miller of Canaccord Genuity.
