Qualcomm, the world’s No. 1 maker of smartphone chips, was fined 242 million euros, or $272 million, by the European Commission on Thursday for blocking a rival from the market about a decade ago. It’s Qualcomm’s second penalty ordered by European regulators.

The European Commission accused Qualcomm of predatory pricing between 2009 and 2011 that was aimed at forcing out Icera, a British phone software maker that is now part of Nvidia.

“Qualcomm’s strategic behavior prevented competition and innovation in the market,” Margrethe Vestager, the competition commissioner, said in a statement.

In a news conference, she later defended the time it had taken to reach a decision — the commission first accused the company of predatory pricing in 2015 — saying it had been a complex case that depended on evidence from Qualcomm.
