American Express Finishes Rockford Purchase

American Express Co. said Thursday it completed its acquisition of Santa Ana-based Rockford Industries Inc., which finances and leases equipment for small businesses. As a result, trading of Rockford’s stock has been discontinued on the Nasdaq market.

Rockford becomes a subsidiary of New York-based American Express, a travel and financial services company that is moving to expand its small-business services.

Only a few overlapping positions might be eliminated as a result of the combination, an American Express spokesperson said.

American Express acquired Rockford for stock.
