What are the key terms of Iridium’s Term Loan B Credit Agreement?

On November 4, 2019, Iridium Satellite entered into a Credit Agreement with Deutsche Bank AG New York Branch as Administrative Agent and Collateral Agent, pursuant to which it borrowed $1.45 billion as a seven-year term loan, which it used to prepay its previous BPIAE Credit Facility.  The Credit Agreement also provides for a $100 million, five-year revolving loan facility.  The term loan initially bore interest at a per annum rate of LIBOR plus an interest rate margin of 3.75%, with a 1.0% LIBOR floor, and was issued at a discount of 0.5% to face value.  Borrowings under the revolving facility bear interest initially at the same per annum rate, with a 0.0% LIBOR floor, no original issue discount, and a commitment fee of 0.5% per year on the undrawn amount.  The interest rate margin applicable to the revolving facility (but not the term facility) will drop to 3.50% if Iridium has a consolidated total net leverage ratio (as defined in the Credit Agreement) of less than 3.5 to 1 but greater than or equal to 3.0 to 1 and will drop to 3.25% if Iridium has a consolidated total net leverage ratio of less than 3.0 to 1.  The commitment fee rate applicable to the revolving facility will drop to 0.375% if Iridium has a consolidated total net leverage ratio of less than 3.5 to 1.  The Credit Agreement also provides for principal payments of 1% per year, with the remaining amount paid at maturity.

On February 7, 2020, the Company closed on an additional $200 million under the term loan. On February 13, 2020, the Company used these proceeds, together with cash on hand, to prepay all of the indebtedness outstanding under its 10.25% senior unsecured notes, including premiums for early prepayment.  The additional amount borrowed under the term loan is fungible with the original $1.45 billion, having the same maturity date, interest rate and other terms, but was issued at a 1.0% premium to face value.

As of December 31, 2020, the Company reported an aggregate balance of $1.64 billion in borrowings under the Term Loan.

On July 28, 2021, Iridium Satellite entered into another amendment of its Credit Agreement. Pursuant to this Amendment, the interest rate was reduced to a per annum rate of LIBOR plus a margin of 2.50%, with a 0.75% LIBOR floor. The borrowings under the Credit Agreement, as amended by this Amendment, were issued at a discount of 0.25% to face value. All other material terms of the Credit Agreement remained the same.

Most recently, on September 20, 2023, the Company refinanced its previously existing term loan resulting in total borrowing of $1.50 billion and an accompanying $100.0 million revolving loan. The Term Loan was issued at a price equal to 99.75% of its face value and bears interest at an annual rate equal to the Secured Overnight Financing Rate (“SOFR”) plus 2.5%, with a 0.75% SOFR floor. The maturity date of the Term Loan is in September 2030. Interest is paid monthly on the last business day of the month. The Revolving Facility bears interest at the same rate (but without a SOFR floor) if and as drawn, with no original issue discount, a commitment fee of 0.5% per year on the undrawn amount, which will be reduced to 0.375% if the Company has a consolidated first lien net leverage ratio (as defined in the Credit Agreement) of less than 3.5 to 1, and a maturity date in September 2028. Principal payments, payable quarterly, beginning with the quarter ending March 31, 2024, will be $15.0 million per annum (equal to one percent of the full principal amount of the Term Loan), with the remaining principal due upon maturity.
