Yeah. No lie. Check it out.
That article is from Bloomberg and I used it as the source of the top 10. If you read the article it is very disingenuous word wise and is misleading. For example, the title is “The Top 10 Defense Contractors”. They provide that top 10 list but I believe the information is from a report of all Federal contractors and not just defense. I tried to get the report but they have it info walled so that you have to register with them to get it.
