Key Terms

first lien, senior secured term debt, internal rate of return, times money invested

4 terms

first lien financial

"including a combination of first lien, senior secured term debt and direct"

A first lien is a legal claim that gives a lender the top priority to be repaid from specific collateral if a borrower defaults or liquidates assets. Think of it as being first in line for the proceeds from a sale—investors who hold a first lien are more likely to recover their money than holders of later claims, so these loans generally carry lower risk and different pricing compared with unsecured or subordinated debt.

senior secured term debt financial

"including a combination of first lien, senior secured term debt and direct"

Senior secured term debt is a loan a company must repay on a set schedule that is backed by specific assets as collateral and has top priority over other creditors if the company cannot pay. Think of it like a mortgage where the lender has first dibs on the pledged property; because it is both secured and senior, it is generally lower risk than unsecured or junior debt and affects a company’s interest costs, borrowing capacity and investor risk.

internal rate of return financial

"the Fund realized an annual internal rate of return ("IRR") of 32.9%"

A percentage that represents the annualized yield an investment would earn, taking into account the timing and amount of all cash inflows and outflows; mathematically it is the rate that makes the discounted sum of future cash flows equal the initial cost. Investors use it to compare different projects or deals the way they compare interest rates — a higher internal rate of return suggests a stronger potential payoff, but it does not by itself show risk, scale, or timing nuances.

times money invested financial

"and a 17.9 times money invested ("TMI") return on its equity investment"

Times money invested, often called the investment multiple, measures how many times an investor’s original cash has been returned or is expected to be returned. Think of putting $1 in and getting $3 back — that would be three times money invested; it shows the scale of profit but doesn’t tell you how long it took or the annual speed of return. Investors use it to compare how much value an investment has delivered regardless of timing.

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.

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.
