HOUSTON – January 18, 2023 – Main Street Capital Corporation (NYSE: MAIN) (“Main Street”) is pleased to announce the expansion of total commitments under its revolving credit facility (the “Credit Facility”) from $920.0 million to $980.0 million. The $60.0 million net increase in total commitments was the result of the addition of a new lender relationship. The recent increase in total commitments was executed under the accordion feature of the Credit Facility, which allows for an increase up to $1.38 billion in total commitments under the facility from new and existing lenders on the same terms and conditions as the existing commitments. The recent increase in total commitments under the Credit Facility provides Main Street with access to additional financing capacity in support of its future investment and operational activities.

Dwayne L. Hyzak, Main Street’s Chief Executive Officer, commented, “We are very pleased that we were able to further diversify our lender group and expand the commitments under our corporate credit facility. Taken together with the recently completed debt private placement and the new SPV credit facility that we executed in the fourth quarter of 2022, these positive developments provide us with access to $415 million of additional debt capital and the ability to repay borrowings that matured in December and to fund the continued growth of our investment portfolio. The confidence shown by these new lending relationships and the continued support from our long-term relationships within our lending group is greatly appreciated.”
