The split of the McLean, Va., company has paved the way for the pairing of two of the region's biggest private businesses, The Washington Post (NYSE:WPO) reported Saturday.

Booz Allen employs 13,000 people and is a top provider of services to the federal government. Carlyle, headquartered in Washington, is a global private equity investment firm with $81.1 billion under its supervision, the Post said.

"Continuing to operate their business as they have will generate a level of growth that will get us the increase in value we're hoping to achieve," said Peter Clare, Carlyle managing director.

Booz Allen had been considering a major reformation for at least two years before announcing the split, the Post said.
