&gt; A quick Google search shows that they paid $11 billion for the company that sells the drug(Sovaldi), and earned $1.3 billion off of it[1] in 2016<p>Well, we are only 1 quarter into 2016, and you are only looking at Sovaldi (when sofosbuvir is also a component of Harvoni)?<p>Q1 2016 is:<p>- $1.3B in sales of Sovaldi<p>- $3.0B in sales of Harvoni<p>So, that&#x27;s $4.3B in sales in Q1, a poor man&#x27;s approximation of multiplying by 4 is $17.2B in sales for 2016 at a gross margin of 87.2%. The profit on drugs that include sofosbuvir as a component in 2016 will probably be over the $11B purchase price.
