Qualcomm is preparing to reject a US$130 billion ($187.7b) takeover offer from US microchip rival Broadcom that, if agreed, would be the biggest technology deal of all time.
Broadcom confirmed the mammoth cash, shares and debt offer today, a proposal that would make it the dominant player in the booming market for mobile semiconductors.
If accepted it would be one of the biggest deals of all time, and double the size of the biggest tech sector deal to date, last year's US$65b sale of EMC to Dell.
However, Qualcomm appears set to reject the offer, with sources blasting it as an opportunistic bid that severely undervalues the company.
Qualcomm is a 32-year-old San Diego company that has been central to the rise of mobile networks, making the modem and computer processors that appear in billions of smartphones.
