Shares of BlackBerry shot up about 16 percent, to $8.92, in heavy trading. Qualcomm was down about 1 percent at $54.81.
The companies in 2016 decided to arbitrate a dispute over Qualcomm’s agreement to cap certain royalties applied to payments made by BlackBerry under a licensing deal.
Qualcomm said on Wednesday it does not agree with the decision of an arbitration panel, but the payment is binding and not appealable.
Qualcomm is also fighting a lawsuit filed by Apple (AAPL), accusing the company of overcharging for chips and refusing to pay some $1 billion in promised rebates.
The U.S. government has accused Qualcomm of resorting to anticompetitive tactics to maintain a monopoly over key semiconductors in mobile phones.
BlackBerry said a final award including interest and that reasonable attorneys’ fees will be issued after a hearing on May 30.
Sullivan & Cromwell represented BlackBerry in the proceeding.
