Qualcomm’s legal troubles are only getting worse. Already embroiled in several lawsuits with Apple, Qualcomm was fined $1.2 billion (997 million euros) today by the European Union for violating antitrust regulations.

From 2011 to 2016, Qualcomm had a deal with Apple to reward the iPhone maker significant rebates if the company exclusively bought LTE modems from Qualcomm. While that might not sound like a huge offense, EU commissioner Margrethe Vestager explained the sanction by saying, “Qualcomm illegally shut out rivals from the market for LTE baseband chipsets for over five years, thereby cementing its market dominance. Qualcomm paid billions of US Dollars to a key customer, Apple, so that it would not buy from rivals.”

At the time, Apple was said to be seriously considering switching from Qualcomm cellular modems to modems made by Intel, but allegedly because of the deal, Apple ended up waiting until after the arrangement expired in 2016 to begin dual-sourcing 4G LTE chips for the iPhone.

“This meant that no rival could effectively challenge Qualcomm in this market, no matter how good their products were,” said Vestager. “Qualcomm’s behaviour denied consumers and other companies more choice and innovation – and this in a sector with a huge demand and potential for innovative technologies. This is illegal under EU antitrust rules and why we have taken today’s decision.”

According to Bloomberg, Qualcomm’s $1.2 billion fine is the third highest antitrust fine in EU history. The award for the EU’s largest fine ever goes to the $3.6 billion sanction levied against major automakers, including Vovlo/Renault, Daimler, and others, for colluding on tricking prices over 14 years. In second place is the less exciting, but still hefty $1.67 billion (1.35 billion euros) fine levied against car glass producers in 2008 over illegal market sharing and price fixing.

Qualcomm says it is planning to appeal the sanctions, though with the company also fending off a potential hostile takeover from fellow chip maker Broadcom, Qualcomm’s resources may be stretched perilously thin. And the bad news doesn’t stop there, because Qualcomm could be looking at a second set of fines from the EU based on allegations that Qualcomm intentionally sold modems to Nvidia at below cost from 2009 to 2011 as a way to exclude rivals from competition.
