Margery Kraus, founder/executive chairman, said the transaction renews her firm’s committee to remain independent.
Launched in 1984, Washington-based APCO gained its independence from Grey Global Group in 2004.
Ted Koenig, founder/CEO of Monroe Capital, looks forward to helping APCO identify growth opportunities including potential acquisitions. “It is especially gratifying to support a successful business that is majority women-owned, which is one of our priority areas for investment capital,” he said in a statement.
Citibank has advised APCO for more than a decade.
Investment banker Petsky Prunier and law firms Gibson Dunn and Godfrey Kahn advised APCO on the transaction.
APCO, which is helmed by Brad Staples, generated $120.6M in fee income last year.
