HOUSTON, March 19, 2024 /PRNewswire/ -- Main Street Capital Corporation (NYSE: MAIN) ("Main Street") is pleased to announce that it recently completed a follow-on investment in an existing portfolio company. Main Street made the investment in Gulf Manufacturing, LLC ("GMI" or the "Company") to support the Company's acquisition of Maass Global Group ("Maass"), a global leader in the manufacture and distribution of flanges and specialty forged products, forged bar, seamless pipe, and fittings in duplex, stainless steel, and high nickel alloys.
