Broadcom Chief Executive Officer Hock Tan is a voracious acquirer, and he’s played a key role in a wave of consolidation engulfing the $300 billion semiconductor industry over the last three years. Broadcom, created in 2016 when Avago Technologies Ltd. acquired Broadcom Corp. for $37 billion, has built itself from a former Hewlett Packard division into one of the largest chipmakers via a string of purchases. Tan has said he wants more deals, a strategy that could be limited by opposition from U.S. regulators.
