“This acquisition is part of our long-term plan to continue to provide an unmatched depth of resources into local markets around the country,” Allied Universal Chief Executive Steve Jones said in a statement.

In November, Allied Universal bought Advent Systems for its technology offerings, SOS Security for its overseas exposure and Vinson Guard Service for its presence in the southeastern U.S.

The combined entity will employ more than 230,000 people with sales topping $7 billion.

APG Security was represented by Triabacus in the transaction.
