Logitech said in prepared earnings remarks, "Our Q3 non-GAAP gross margin expanded 760 basis points to 45.2%, driven by higher sales volume, favorable product mix, continued focus on maintaining low promotional spending, and currency exchange rate tailwinds. While gross margin has been above our target range of 36-40%, we continue to expect to see increased promotional spend as supply stabilizes and we are actively exploring opportunities to reinvest our gross margin rate upside into economically attractive online and retail initiatives. As a result, we do not expect this level of gross margin to sustain."

CommScope filed an additional patent infringement lawsuit in Germany against SOLiD, a manufacturer of distributed antenna systems based in South Korea. The complaint asserts German part of European Patent No. EP 2290850B1 relating to CommScope's digital DAS innovations against SOLiD's Genesis DAS product. CommScope asserted the United Kingdom part of this patent against SOLiD's Genesis DAS product in the U.K. last year. CommScope also enforced the U.S. counterparts of EP 2290850B1 in separate U.S. patent infringement actions against Dali Wireless and SOLiD. The U.S. action against SOLiD was filed in May of 2020 and, after noting that SOLiD withdrew its Genesis DAS product from the U.S. market, CommScope voluntarily dismissed that action.
