Provides $12.7 Million of Financing to UBM ParentCo, LLC
Generates $6.0 Million Realized Gain from the Exit of Equity Investment in Mystic Logistics Holdings, LLC
HOUSTON, Jan. 6, 2026 /PRNewswire/ — MSC Income Fund, Inc. (NYSE: MSIF) (“MSC Income” or the “Fund”) is pleased to announce that it recently completed a new portfolio investment totaling $12.7 million in UBM ParentCo, LLC, doing business as United Business Mail (“UBM” or the “Company”), to facilitate UBM’s merger with Mystic Logistics Holdings, LLC (“Mystic”), an existing MSC Income portfolio company. The Fund partnered with the Company’s and Mystic’s existing owners and management teams and Main Street Capital Corporation (NYSE: MAIN) (“Main Street”) to facilitate the transaction, with the Fund’s new investment including a combination of first lien, senior secured term debt and direct minority equity. As a result of the transaction, the Fund fully exited its debt and equity investments in Mystic and is now a lender and minority equity owner in UBM.
UBM is a leading provider of “marketing mail” commingle services, specializing in optimizing postage, transportation and delivery performance for large-scale mailers. Through a nationwide logistics network and technology-driven processes, UBM helps clients improve speed-to-market, visibility and cost efficiency across their marketing mail programs.
Mystic specializes in marketing mail consolidation and logistics solutions designed to support precise, date-driven in-home delivery performance. Through disciplined transportation planning, mail flow optimization and performance tracking, Mystic helps clients align marketing campaigns with targeted in-home delivery windows to drive consistent and measurable results.
The Fund originally partnered with Mystic’s executive management team through a co-investment with Main Street to facilitate a majority recapitalization in August 2014. The Fund’s initial investment consisted of a $2.5 million first lien, senior secured term loan and a $0.7 million equity investment. After the Fund’s initial investment, Mystic experienced significant growth as the company expanded its customer base and strengthened its postal and commercial partnerships.
The Fund realized a gain of $6.0 million on the exit of its equity investment in Mystic and also received total dividends of $5.5 million over the life of its equity investment. As a result, on a cumulative basis since the Fund’s initial investment in August 2014 and taking the realized gain and dividends into consideration, the Fund realized an annual internal rate of return (“IRR”) of 32.9% and a 17.9 times money invested (“TMI”) return on its equity investment in Mystic. On a cumulative basis including both the Fund’s debt and equity investments, the Fund realized an IRR of 22.9% and a 5.1 TMI return.
