The sanctions imposed on Huawei have dealt a heavy blow to Broadcom, which last year sold $900 million worth of semiconductors to the Chinese electronics giant. Broadcom, which reported annual sales of $20.8 billion in 2018, has also been burned by the trade war between Beijing and Washington. The U.S. has slapped tariffs on some chips and other products imported from China, which is where Broadcom makes more than 50% of its revenue.
