Broadcom and Qualcomm
Featuring Hock Tan
In 2018, Broadcom launched a roughly $117 billion hostile bid for Qualcomm, set to be the largest technology acquisition in history. The US government killed it in about two months. Hock Tan was known for buying chipmakers, cutting costs, and extracting cash flow, but Qualcomm held some of the most valuable wireless patents in the world and sat at the center of 5G. CFIUS forced a delay, then a presidential order blocked the deal outright on national security grounds. Broadcom offered to redomicile in the US. It did not matter.
For founders and operators thinking about M&A, partnerships, or any large transaction, this case sharpens a risk that lives entirely outside the negotiation. It asks whether a non-business stakeholder, a government, regulator, union, or community, holds effective veto power in your industry, and whether you have mapped it. The specific limit that no price, promise, or restructuring can overcome, and how you'd spot it early, is the diligence lesson the case keeps for the end.
Frequently asked questions
What was the Broadcom Qualcomm deal?
It was a roughly $117 billion hostile takeover bid Broadcom launched for Qualcomm in 2018, which would have been the largest technology acquisition in history. Broadcom's CEO Hock Tan was known for buying chipmakers, cutting costs, and extracting cash flow. The US government blocked the deal in about two months on national security grounds.
Why did the US block Broadcom's bid for Qualcomm?
The deal was blocked on national security grounds because Qualcomm held some of the most valuable wireless patents in the world and sat at the center of 5G. CFIUS forced a delay and then a presidential order stopped the deal outright. Broadcom even offered to redomicile in the US, and it did not matter.
Why was the Broadcom Qualcomm acquisition important?
It is a landmark example of a deal killed by a stakeholder sitting entirely outside the negotiation. No price, promise, or restructuring could overcome the government's national security veto, since Qualcomm's role in 5G leadership made it strategically untouchable. The case shows how regulatory and political risk can override business logic.
What can operators learn from Broadcom Qualcomm about M&A risk?
The lesson is to map whether a non-business stakeholder such as a government, regulator, union, or community holds effective veto power in your industry before you commit. Broadcom understood the business case perfectly but missed the limit that no offer could overcome.
