Mohegan Gaming & Entertainment Announces Closing of Refinancing Transactions

UNCASVILLE, Conn., Jan. 26, 2021 /PRNewswire/ — Mohegan Gaming & Entertainment (“MGE” or the “Company”) today announced the closing of its previously announced refinancing transactions, including a notes offering and entry into a new credit agreement.

On January 26, 2021, the Company closed its previously announced private offering (the “Offering”) of $1.175 billion in aggregate principal amount of 8.000% second priority senior secured notes due 2026 (the “Notes”). The notes are guaranteed by certain of the Company’s subsidiaries.

The Company has also entered into a Credit Agreement providing for approximately $263 million in a new revolving senior secured credit facility (the “New Senior Secured Credit Facility”).

The Company applied the net proceeds from the Offering and borrowings under the New Senior Secured Credit Facility, together with cash on hand, to fund the repayment, satisfaction and discharge of certain existing indebtedness of MGE, including all loans outstanding under MGE’s previous senior secured credit facilities, all obligations in respect of MGE’s Main Street term loan facility and MGE’s debt to the Mohegan Tribe in respect of certain subordinated loans, and to pay related fees and expenses.

The Notes were offered in a private placement to persons reasonably believed to be “qualified institutional buyers” pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act. The Notes have not been registered under the Securities Act or any state or other securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws.
