Peraton Ranked in the 2021 Defense News Top 100

  • Company ranked #96 based on reporting $651M in defense-related revenues

  • Accounting for the recent acquisitions of Perspecta and Northrop Grumman’s integrated mission support and IT solutions business, the new Peraton would have ranked in the top 25 with combined defense-related revenues of approximately $5.5B

CHANTILLY, VA — July 14, 2021 – Peraton, the world’s leading mission capability integrator and transformative enterprise IT provider, has been ranked as one of the world’s largest defense companies in the 2021 Defense News Top 100. It is the company’s second year appearing on the annual ranking of the largest global defense and national security companies shaping militaries around the world.

Peraton ranked #96 on this year’s list after reporting $651.2 million in defense-related revenue for calendar year 2020. Perspecta, which Peraton acquired in May 2021, ranked #39 on the list after reporting $3.1 billion in defense-related revenue.

The collective 2020 defense-related revenues of heritage Peraton, heritage Perspecta and Northrop Grumman’s integrated mission support and IT solutions business—which Peraton acquired in February 2021—totaled approximately $5.5 billion. If the combined company had existed last year, it would have ranked in the top 25 in the world on the 2021 Defense News Top 100 list, ahead of companies like Booz Allen, GE, CACI, and SAIC.

“While we are proud to see Peraton place on the Defense News 100 again, our ranking on this year’s list is a snapshot of the $1 billion mid-sized company we were last year, not a full depiction of the top-tier mission capability integrator we are after completing two major acquisitions in the first half of 2021,” said Matt McQueen, Peraton’s chief communications & engagement officer.

“Today, as one of the world’s leading national security companies, Peraton serves as a valued partner to essential government agencies across the intelligence, space, cyber, defense, civilian, health, state and local markets,” said McQueen.

“We have built a $7 billion company that is strong on defense, but we also recognize that recent events have underscored the fact that the national security, health security, financial security, and commerce security of our citizens are inextricably linked. The new Peraton is now positioned to operate at this critical nexus, delivering differentiated and proven technology solutions across a broad set of government customers, helping keep Americans and our allies safe and secure.”

Peraton supports some of the most important and sensitive government programs around the globe. Notable defense and national security customers include the U.S. Space Force, U.S. Air Force, U.S. Navy, U.S. Army, National Reconnaissance Office, Missile Defense Agency, Defense Intelligence Agency, Department of Homeland Security, and the Department of Justice, as well as the Royal Canadian Air Force.
