Rocket Lab Completes $1.94 Billion Equity Raise, Fully Funding Iridium Acquisition

Rocket Lab has fully financed its pending acquisition of Iridium Communications, completing a $1.944 billion at-the-market equity offering and securing the cash consideration needed to close the deal. The company also terminated a $3.6 billion bridge facility, removing a major financing risk ahead of the transaction, which is expected to close in mid-2027. Rocket Lab shares rose about 4 percent on the news.

The financing milestones center on a deal that would transform Rocket Lab from a launch and space systems company into an operator of a global satellite communications network. The Iridium acquisition, valued at roughly $8 billion, represents one of the largest deals in commercial space, and clearing the financing removes the biggest overhang on the transaction.

Rocket Lab raised approximately $1.944 billion in gross proceeds through the issuance of 29.3 million shares before commissions and offering expenses. The company intends to use the net proceeds to fund cash payments under the acquisition. If the deal is not consummated or if there are excess proceeds, Rocket Lab intends to use the funds for future growth, including potential future acquisitions, and for general corporate and working capital purposes.

On September 15, 2026, Iridium entered into a Change of Control Amendment to its existing term loan facility for its outstanding $1.775 billion in term loans, obtaining consent from the requisite lenders to carve out Rocket Lab's pending acquisition from the credit agreement's definition of change of control. As part of the amendment, Rocket Lab USA, Inc., the company's primary operating subsidiary and anticipated parent company of Iridium, will provide an unsecured guarantee of the Iridium term loan upon closing. The company said the amendment will provide cost-effective, permanent financing supported by Iridium's substantial free cash flow.

The Iridium term loan, together with the ATM proceeds and other unrestricted cash and cash equivalents available to the company, represent an amount sufficient to pay the required cash consideration, repay certain Iridium indebtedness other than the term loan, and pay related fees and expenses at closing. In connection with the amendment, Rocket Lab terminated its $3.6 billion debt commitment for a senior secured debt bridge facility it had entered into on June 28, 2026, in connection with the merger agreement.

The company described the completion of the amendment and the ATM proceeds as another significant milestone in its pending acquisition of Iridium. The transaction remains subject to regulatory approvals and is expected to be completed in mid-2027.

The acquisition remains subject to regulatory approvals and Iridium stockholder approval. On August 26, 2026, the Registration Statement on Form S-4 was declared effective, Iridium filed its definitive proxy statement, and Rocket Lab filed its final prospectus, with materials sent to Iridium stockholders beginning on or about that date seeking approval of transaction-related proposals. With the money in hand, the remaining question is whether Rocket Lab can operate a constellation as well as it builds and launches one.
