According to the National Center for the Middle Market, the U.S. middle market saw a 5% increase in revenue growth compared to the S&P 500’s 1% revenue increase last year – demonstrating the mid-market’s position as a key engine of growth for the U.S. economy.

Mid-market business leaders expect an increased need for working capital, capital expenditures and acquisitions in 2014, says GE Antares Capital, a middle market lender to private equity-backed companies.

“Despite challenges like healthcare and increasing operating costs, the overall financial health of middle market companies continues to improve,” said John Martin, president and CEO of GE Antares Capital. “We anticipate increased investment activity, especially within the technology, media, telecom and energy sectors throughout the year.”
