Press Release

LOWELL, Mass.--(BUSINESS WIRE)-- MACOM Technology Solutions Holdings, Inc. (NASDAQ: MTSI) (MACOM), a leading supplier of high-performance analog RF, microwave, millimeterwave and photonic semiconductor products, today announced that the United States District Court for the Central District of California in Los Angeles has granted MACOM's request for a preliminary injunction in MACOM's lawsuit against Infineon Technologies Americas Corp. ("Infineon") over Gallium Nitride on Silicon (GaN-on-Si) technology rights.

The Court's October 31, 2016 decision (i) confirmed MACOM's continuing exclusive rights in certain GaN-on-Si RF fields under a 2010 License Agreement entered into between Nitronex (acquired by MACOM in 2014) and International Rectifier (acquired by Infineon in 2015); (ii) ruled that MACOM is likely to succeed on its claim that Infineon's purported termination of that Agreement was improper and without effect; and (iii) granted MACOM's motion for a preliminary injunction prohibiting Infineon from engaging in activities inconsistent with the 2010 License Agreement pending the Court's final decision in the case.

"We were forced to file this lawsuit to stand up to Infineon's bullying and anticompetitive behavior. We are gratified by the Court's preliminary decision confirming that the GaN-on-Si rights granted to us under the 2010 License Agreement remain in full force and effect and that Infineon acted improperly in trying to operate in our exclusive field of use," said John Croteau, President and Chief Executive Officer of MACOM. "We are firmly committed to vigorously litigating this case to its rightful conclusion. We continue on the path to providing GaN-on-Si technology that promises to improve network data service and cell coverage of 4G/LTE and 5G basestations that will benefit people worldwide."
