Which tech company acquisition was the biggest by dollar amount?
Dell's buyout of EMC in 2015
Microsoft's buyout of LinkedIn in 2016
Google's buyout of Motorola in 2011
HP's buyout of Compaq in 2002
Correct Answer:Dell's buyout of EMC in 2015
A brief explanation why…
It may not be the most recognizable deal, but Dell's acquisition of enterprise storage company EMC for $67 billion in cash and stock stands as the tech industry's largest buyout. Second place goes to Microsoft's purchase of LinkedIn for $26.2 billion in 2016.
HP's takeover of Compaq in 2002 is virtually tied with Facebook's buyout of WhatsApp for third with both being ~$19 billion exchanges (the HP-Compaq deal is often cited as being $25-$33 billion but it fell to $18.6 billion in the end). HP's $15.4 billion acquisition of Ross Perot's IT services company EDS in 2008 is also notable, and for completion's sake, Google paid $12.5 billion for Motorola and sold it to Lenovo two years later for $2.9 billion (minus all the patents).
You may be wondering why AOL's buyout of Time Warner isn't among the answers, considering it was a larger deal than any of those, with AOL paying $106 billion for Time Warner in 2000 (it was actually originally $165 billion but later reduced). However, that acquisition is typically excluded from this sort of list because AOL and Time Warner are considered media companies more than tech companies.
