HOUSTON, Nov. 19, 2021 /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, along with its co-investor, made the investment in GRT Rubber Technologies LLC ("GRT" or the "Company") to support the Company's acquisition of Valley Rubber, L.L.C. ("Valley"), a complementary business in the engineered rubber products industry, significantly expanding the Company's customer base and product offerings. The follow-on investment consists of an additional $22.1 million first lien, senior secured term debt investment.

Headquartered in Paragould, Arkansas, with business origins dating back to 1880, GRT is a leading manufacturer of engineered rubber products, including conveyor belts and sheet rubber products for many applications across a diversified array of end-markets. Over its 100+ year history, the Company has developed strong brands and a reputation for high quality, reliable products and differentiated customer service.

Additionally, this acquisition provides incremental sales channel and end-market diversification. Main Street made its initial investment in GRT during the fourth quarter of 2014.

Founded in 1967 and headquartered in Falkville, Alabama, Valley is a manufacturer of custom engineered rubber products, including rubber wear liners, truck bed liners, screen media and other rubber products for mining, aggregates, infrastructure and industrial applications.
