Booz Allen Hamilton(NYSE: BAH) has finalized its purchase of EverWatch from investment firm Enlightenment Capital, as part of efforts to accelerate mission delivery and technology development cycles in support of national security customers.

Booz Allen said Friday the acquisition gives the company access to EverWatch’s cleared personnel and expertise in analytics, software development, artificial intelligence, machine learning, cloud and technical signals intelligence.

John Hillen, CEO of EverWatch and a previous Wash 100 awardee, said the two companies “share a passion for the national security mission, advanced innovation and technical excellence.”

Tom Pfeifer, president of Booz Allen’s national security sector, said EverWatch’s technical capabilities, national security expertise and workforce complement Booz Allen’s portfolio of cyber operations, AI, mission analytics and 5G offerings and the combination will deliver value to customers as the companies work to transform U.S. cyber capabilities.

The transaction was first announced in March. Last week, a federal court ruling allowed the acquisition to push through after a judge declined to grant a preliminary injuction sought by the Department of Justice against the deal over competition concerns.

Baird and Moore & Van Allen served as financial and legal advisers, respectively, to EverWatch, which will operate as Booz Allen’s wholly owned subsidiary.

Jefferies was Booz Allen’s financial adviser and King & Spalding acted as legal counsel to the company in the transaction. Avascent offered strategic industry advisory support to the McLean, Virginia-based consulting firm.
