Iridium (IRDM) closes $366.7M Aireon deal, assumes and guarantees Aireon term loans
Rhea-AI Filing Summary
Iridium Communications Inc. completed its acquisition of the remaining 61% of Aireon Holdings LLC for approximately $366.7 million, giving it full ownership of Aireon and its subsidiary Aireon LLC. Half of the price was paid in cash and half via a seller loan.
That deferred portion is a $183.36 million one-year, interest-free term loan secured by Aireon equity under a new Credit and Guaranty Agreement with customary covenants and default provisions. Iridium also provided an unsecured Parent Guaranty of Aireon LLC’s existing term loans, which had an original principal of $175 million and an aggregate principal balance of $154.7 million as of the filing. These term loans mature on October 10, 2028 and carry SOFR- or base-rate-based interest with substantial quarterly amortization and a maximum consolidated total leverage ratio of 5.0 to 1.0.
Separately, in connection with the previously announced Agreement and Plan of Merger under which Rocket Lab Corporation agreed to acquire Iridium, the compensation committee approved cash retention awards for two named executive officers, payable in tranches tied to the merger closing, a six-month anniversary, or certain termination and severance events. Iridium also highlighted that Rocket Lab will file a Registration Statement on Form S-4 containing a joint proxy statement/prospectus seeking stockholder approval for transaction-related proposals.

Insights
Iridium adds Aireon fully while assuming and layering debt commitments.
The acquisition brings Aireon entirely under Iridium for about $366.7 million, split between cash and a $183.36 million seller term loan that is interest-free for one year and secured by Aireon equity. This structure limits immediate cash outflow but adds a short-dated maturity.
Aireon LLC’s existing Term Loans, originally $175 million and now at $154.7 million, bear relatively high margins of 6.25% over SOFR or 5.25% over a base rate, with increasing quarterly amortization and a maximum consolidated total leverage ratio of 5.0 to 1.0. These features create scheduled deleveraging but also raise ongoing interest and covenant-management demands.
The new Parent Guaranty brings Iridium directly behind Aireon’s obligations, deepening linkage between the businesses. Cash-based retention awards for key executives, tied to the pending Rocket Lab merger milestones and possible change-of-control outcomes, aim to support execution through closing and integration, with specific payment timing governed by merger completion or termination events.

Item 1.01 Entry into a Material Definitive Agreement.
On July 2, 2026 (the “Aireon Closing Date”), Iridium Communications Inc. (the “Company”), through its wholly owned subsidiary Iridium Monitor Holdings LLC (“Iridium Monitor Holdings”), completed its previously announced acquisition of the remaining 61% of equity interests in Aireon Holdings LLC (“Aireon”) that the Company did not already own pursuant to a Securities Purchase Agreement with NAV CANADA, the Irish Air Navigation Service, ENAV S.P.A., Naviair Surveillance A/S, NATS (Services) Limited, and certain of their affiliated entities (collectively, the “Sellers”). The Company now indirectly owns all of the membership interests in Aireon and its subsidiary Aireon LLC. The aggregate purchase price payable to the Sellers was approximately $366.7 million, of which 50% was paid in cash at the closing of the acquisition (the “Aireon Closing”) and the remainder was deferred in the form of a loan from the Sellers.
Credit and Guaranty Agreement
In connection with the deferred portion of the purchase price, on the Aireon Closing Date, Iridium Monitor Holdings, as borrower, and the Sellers entered into a Credit and Guaranty Agreement (the “Credit and Guaranty Agreement”) pursuant to which the Sellers provided Iridium Monitor Holdings with a $183.36 million term loan, bearing no interest, and maturing one year following the Aireon Closing Date, to fund the deferred portion of the purchase price. The loan is secured by a first priority lien on the equity interests of Aireon and other intermediate holding company entities.
The Credit and Guaranty Agreement contains no financial maintenance covenants, and contains customary representations and warranties, affirmative and negative covenants (including limitations on indebtedness, liens, restricted payments, investments and affiliate transactions), and events of default (including payment defaults, breaches of covenants, cross-defaults, bankruptcy and change of control). Upon the occurrence of an event of default, the lenders may accelerate the obligations under the Credit and Guaranty Agreement, subject to mandatory acceleration for certain bankruptcy events. The loan is subject to voluntary prepayment at any time subject to prior written notice, and mandatory repayment out of the net cash proceeds of new indebtedness or the issuance or sale of equity interests or in the event of a change of control.
Aireon Credit Agreement
As a result of the Aireon Closing, on a going forward basis, Aireon LLC’s previously existing credit facility will be consolidated with the financial position and results of operations of the Company. That credit facility provides for a secured term loans in the original aggregate principal amount of $175 million (the “Term Loans”) with a scheduled maturity date of October 10, 2028, and is reflected in a Credit and Guaranty Agreement, dated as of October 10, 2023, as amended by the First Amendment to Credit and Guaranty Agreement, dated as of July 2, 2026, by and among Aireon LLC as borrower, Aireon and other subsidiaries of Aireon from time to time party thereto as guarantors (together with Aireon, the “Aireon Guarantors”), GLAS USA LLC, as administrative agent, GLAS Americas LLC, as collateral agent, and the lenders from time to time party thereto (as amended, the “Aireon Credit Agreement”). As of the date hereof, the aggregate principal balance of the Term Loans is $154.7 million.
In connection with the Aireon Closing, on July 2, 2026, the Company entered into a Parent Guaranty Agreement (the “Parent Guaranty”), pursuant to which the Company provided an unsecured guarantee of the repayment of Aireon LLC’s obligations under the Aireon Credit Agreement.
The Term Loans bear interest at a per annum rate equal to, at Aireon LLC’s option, either (i) a SOFR-based rate plus a margin of 6.25% or (ii) a base rate plus a margin of 5.25%. In the event of a prepayment of all or a portion of the Term Loans, subject to certain exceptions, Aireon LLC is required to pay a prepayment premium equal to (x) 3.00% of the aggregate principal amount of Term Loans so prepaid, if such prepayment is made on or prior to October 10, 2026, and (y) 1.00% of the aggregate principal amount of Term Loans so prepaid, if such prepayment is made after October 10, 2026 and on or prior to October 10, 2027. The Aireon Credit Agreement currently requires quarterly amortization payments equal to 1.875% of the original principal amount of the Term Loans, with such quarterly amortization payments increasing to 3.125% of the original principal amount of the Term Loans beginning with the quarter ending December 31, 2026 and each quarter thereafter until maturity.

Aireon and, subject to certain exceptions, substantially all of Aireon LLC’s existing and future direct and indirect wholly owned subsidiaries are required to guarantee the repayment of Aireon LLC’s obligations under the Aireon Credit Agreement. The obligations of Aireon LLC and each of the Aireon Guarantors with respect to the Aireon Credit Agreement are secured by a pledge of substantially all assets of Aireon LLC and each Aireon Guarantor.
The Aireon Credit Agreement contains customary representations and warranties and affirmative and negative covenants applicable to Aireon and its subsidiaries, including limitations on the ability of Aireon and its subsidiaries to incur debt, permit additional liens, make investments and acquisitions, merge or consolidate with others, dispose of assets, pay dividends and distributions, pay junior indebtedness and enter into affiliate transactions, in each case, subject to certain exceptions. In addition, the Aireon Credit Agreement contains a financial covenant requiring Aireon and its subsidiaries to maintain, on a consolidated basis as of the last day of each quarterly period, a consolidated total leverage ratio, as defined in the Aireon Credit Agreement, of not more than 5.0 to 1.0. The Aireon Credit Agreement also includes events of default customary for facilities of this type. Upon the occurrence of an event of default, among other things, all outstanding Term Loans may be accelerated and collateral remedies may be exercised.
