The deal brokered between OmniVision Technologies Inc. and Shanghai-based company Will Semiconductor Co. Ltd was so quiet that it didn’t become public knowledge until a year later in 2019. According to documents published in April of that year, over $2.1 billion exchanged hands.

With little to no fanfare and no public statement released, the details of the sale remain unclear. However, the company first became involved with Chinese investors in 2015 when several chinese companies banded together to pay $1.9 billion for the California-based business. Will Semiconductor Co. Ltd is not a well-known company by any means, making the takeover somewhat of a mystery.
