Rhea-AI Filing Summary

Rocket Lab Corporation (RKLB) reported that it has fully arranged financing for its pending acquisition of Iridium Communications Inc. through a completed equity program and amended term debt at Iridium. The company raised approximately $1.944 billion in gross proceeds via its At-The-Market share sale, issuing 29.3 million shares, and intends to use the net proceeds primarily to fund cash payments under the Iridium acquisition.

Iridium’s existing term loan facility, covering $1.775 billion of term loans, was amended so Rocket Lab’s acquisition will not be treated as a change of control, allowing the loans to remain outstanding after closing. Upon completion of the transaction, Rocket Lab USA, Inc. will provide an unsecured guarantee of the Iridium term loan, and interest margins will increase within stated ranges, with a 1.00% exit fee on certain prepayments and a 1.00% prepayment premium in repricing transactions. With the amended Iridium term loan, ATM proceeds and other available cash, Rocket Lab states it has sufficient funds to cover required cash consideration, certain Iridium debt repayments and related expenses, and has terminated its prior $3.6 billion senior secured bridge loan commitment. The Iridium acquisition is described as expected to close in mid‑2027.

Positive

  • $1.944 billion raised via the ATM Program and the $1.775 billion Iridium term loan provide sufficient funding to cover Iridium acquisition cash consideration, selected debt repayment, and related fees and expenses.
  • Amendment of Iridium’s credit agreement so the Rocket Lab transaction is not a Change of Control allows the existing term loans to remain outstanding post‑closing, avoiding mandatory refinancing at closing.
  • Termination of the $3.6 billion senior secured bridge facility removes reliance on short‑tenor bridge financing for the Iridium acquisition.

Negative

  • Completion of the ATM Program required issuance of approximately 29.3 million new shares, creating equity dilution for existing Rocket Lab stockholders.
  • The amended Iridium term loan includes higher interest margins and adds a 1.00% exit fee on certain prepayments and a 1.00% prepayment premium on repricing transactions, increasing future financing costs.

At-The-Market share sale financial
"Rocket Lab has completed its previously announced At-The-Market share sale"
Change of Control financial
"amend the definition of “Change of Control” under the credit agreement"
A change of control occurs when the ownership or management of a company shifts significantly, such as through a sale, merger, or acquisition, resulting in new leadership or ownership structure. This change can impact the company's direction and decision-making, which is important for investors because it may affect the company's stability, strategy, and future prospects.
term loan facility financial
"its existing term loan facility for its outstanding $1.775 billion term loans"
A term loan facility is a type of loan provided by a lender that is repaid over a set period of time, usually with fixed payments. It functions like a large, upfront loan that a borrower agrees to pay back gradually, often used to fund major investments or projects. For investors, understanding a company's use of such loans helps assess its financial stability and risk level.
Registration Statement on Form S-4 regulatory
"Rocket Lab h ... a Registration Statement on Form S-4 that includes"
A registration statement on Form S-4 is a formal filing with the U.S. Securities and Exchange Commission used when a company issues shares or other securities as part of a merger, acquisition, exchange offer or similar corporate deal. It bundles the transaction terms, financial statements, risk factors and shareholder vote materials so investors can assess the deal; think of it as a detailed prospectus or buyer’s packet that explains what you would own and how the deal could change your stake.
exit fee financial
"provide for an exit fee, which applies after the first anniversary"
A fee charged when an investor or customer ends a position, redeems shares, or terminates a contract before a set time. It functions like a penalty for breaking an agreement — similar to an early-cancellation charge on a subscription — and reduces the cash you receive from a sale or withdrawal. Investors care because it can lower net returns, influence the timing of trades, and change the true cost of exiting an investment.
prepayment premium financial
"provide for a prepayment premium, applicable only in the case of a repricing"
A prepayment premium is a fee a borrower pays when they pay off a loan or debt earlier than agreed, like an early-termination charge on a phone contract. For investors, it affects the timing and amount of cash they receive from loans or mortgage-backed securities, changing expected returns and reinvestment plans because early repayment can return principal sooner or come with extra compensation.

Iridium Credit Agreement Amendment

 

Iridium is a party to that certain Amended and Restated Credit Agreement, dated as of September 20, 2023 (as amended, supplemented or otherwise modified, the “Existing Iridium Credit Agreement”), among Iridium Holdings LLC, a Delaware limited liability company (“Holdings”), solely with respect to Section 10.12 thereof, Iridium, Iridium Satellite LLC, a Delaware limited liability company (the “Borrower”), the Lenders party thereto from time to time and Deutsche Bank AG New York Branch, as the Administrative Agent (the “Administrative Agent”) and the Collateral Agent.

 

On September 15, 2026, Holdings, Iridium, the Borrower, the Subsidiary Guarantors, the Administrative Agent, the Collateral Agent and the Lenders on the signature pages thereto (constituting at least the Required Lenders as defined in the Existing Iridium Credit Agreement, the “Consenting Lenders”) entered into a Consent and Amendment No. 4 (“Consent and Amendment No. 4”) to the Existing Iridium Credit Agreement (as so amended, the “Amended Iridium Credit Agreement”) to, among other things, (i) provide that the Transaction will not constitute a Change of Control (as defined in the Amended Iridium Credit Agreement) under the Amended Iridium Credit Agreement, (ii) provide that the requisite lenders under the Existing Iridium Credit Agreement expressly consent to the Transaction, (iii) provide for a downstream guarantee of the obligations under the Amended Iridium Credit Agreement by Rocket Lab USA, Inc., the Company’s primary operating subsidiary, upon the closing of the Transaction, and (iv) make certain other amendments to account for the Transaction, which other amendments shall only take effect upon the consummation of the Transaction (and subject to the occurrence thereof). The other amendments, solely from and after the closing of the Transaction (and subject to the occurrence thereof): (i) increase the interest rate applicable to the term loans outstanding under the Existing Iridium Credit Agreement to a per annum rate of (a) SOFR plus an interest rate margin that ranges from 2.50% to 3.00% or (b) base rate plus an interest rate margin that ranges from 1.50% to 2.00%, in each case, based on the Company’s credit ratings, (ii) provide for an exit fee, which applies after the first anniversary of the closing of the Transaction, in an amount equal to 1.00% of term loans prepaid and (iii) provide for a prepayment premium, applicable only in the case of a repricing transaction (and in any event, not in the case of a change of control or transformative transaction), in an amount equal to 1.00% of term loans subject to such repricing transaction.

 

  

 

 

As a result of Consent and Amendment No. 4, the Transaction will not constitute a change of control under the Amended Iridium Credit Agreement and the term loans outstanding under the Amended Iridium Credit Agreement will be permitted to remain outstanding after closing of the Transaction.

Termination of Bridge Debt Commitment

In connection with the Merger Agreement and as previously disclosed, on June 28, 2026, Rocket Lab entered into a commitment letter, as well as related fee letters, with Deutsche Bank Securities Inc., Wells Fargo Bank, National Association, Deutsche Bank AG New York Branch, and Wells Fargo Securities, LLC, pursuant to which Deutsche Bank AG New York Branch and Wells Fargo Bank, National Association have committed to provide, subject to the terms and conditions thereof, a 364-day senior secured bridge term loan facility in an aggregate principal amount of $3.6 billion (the “Bridge Debt Commitment”).

 

Pursuant to the terms of the commitment letter, the Bridge Debt Commitment was reduced automatically by a combination of net proceeds received by Rocket Lab from equity offered under Rocket Lab’s previously announced replacement equity distribution agreement, dated August 13, 2026, with Deutsche Bank Securities Inc., Wells Fargo Securities, LLC, Deutsche Bank AG, London Branch and Wells Fargo Bank, National Association under which it may offer and sell shares of Rocket Lab’s common stock (the “Shares”) having an aggregate offering price of up to approximately $1.944 billion from time to time pursuant to an “at the market” program (the “ATM Program”) and the $1.775 billion of term loans available under the Amended Iridium Credit Agreement upon the consummation of the Transaction. The Bridge Debt Commitment was formally terminated in full on September 15, 2026 prior to the effectiveness of the Consent and Amendment No. 4. As of September 15, 2026, Rocket Lab had raised approximately $1.944 billion in gross proceeds, before commissions and expenses, through the sale of approximately 29.3 million Shares under the ATM Program.

 

The net proceeds raised to date under the ATM Program, together with the Amended Iridium Credit Agreement and other available cash and sources of funding available to Rocket Lab, will be sufficient to pay the anticipated cash payments required in connection with the completion of the Iridium Acquisition.

Exhibit 99.1 

Rocket Lab Fully Funds Iridium Acquisition, Including Completion of $1.94 Billion ATM

 

Iridium Acquisition Now Fully Financed: Rocket Lab completes the $1.944 billion At-The-Market (ATM) equity offering, securing the required cash consideration (alongside available liquidity) to fully fund its pending acquisition of Iridium Communications - expected to close in mid-2027, pending regulatory approvals.

Cost-Effective Debt Structure Secured: Iridium amends its existing $1.775 billion credit facility to permit the change of control, establishing long-term, cost-effective permanent financing backed by Iridium’s strong free cash flow and a parent guarantee from Rocket Lab USA.

Bridge Facility Terminated: Rocket Lab successfully cancels the initial $3.6B senior secured bridge facility, de-risking the capital structure ahead of the targeted close of the acquisition in mid-2027.

 

Long Beach, California. September 15, 2026 – Rocket Lab Corporation (Nasdaq: RKLB) (“Rocket Lab” or the “Company”), a global leader in launch services and space systems, today announced it has successfully completed several critical milestones to fully finance its pending acquisition of Iridium Communications Inc. (“Iridium” and such pending transaction, the “Iridium Acquisition”).

 

ATM Program Update

 

Rocket Lab has completed its previously announced At-The-Market share sale (the “ATM Program”), raising approximately $1.944 billion in gross proceeds through the issuance of 29.3 million shares (before commissions and offering expenses).

 

Rocket Lab intends to use the net proceeds from the ATM Program to fund cash payments under the Iridium Acquisition. If the Company does not consummate the Iridium Acquisition or if it has excess proceeds from the offering of shares under the ATM Program, the Company intends to use the net proceeds to fund future growth, including potential future acquisitions, and for general corporate and working capital purposes.

 

Change of Control Consent and Amendment for Iridium Existing Credit Agreement

 

On September 15, 2026, Iridium entered into an amendment (the “Change of Control Amendment”) to its existing term loan facility for its outstanding $1.775 billion term loans (as of June 30, 2026) (the “Iridium Term Loan”) to obtain consent from the requisite lenders to, among other things, amend the definition of “Change of Control” under the credit agreement to carve out Rocket Lab’s pending acquisition of Iridium. As part of the Change of Control 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 the closing of the Iridium Acquisition.

 

  

 

 

The completion of the Change of Control Amendment will provide Rocket Lab with cost-effective, permanent financing upon the closing of the Iridium Acquisition, supported by Iridium substantial free cash flow.

 

Termination of Debt Commitment Letter

 

The Iridium Term Loan, together with the proceeds raised to date under the ATM Program 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 Iridium Term Loan) and pay related fees and expenses at the closing of the Iridium Acquisition. In connection with the consummation of the Change of Control Amendment the Company also terminated its $3.6 billion debt commitment for a senior secured debt bridge facility it had entered into in connection with the Iridium Acquisition merger agreement on June 28, 2026. 

 

The completion of the Change of Control Amendment and the proceeds raised under the ATM Program is another significant milestone in the Company’s pending acquisition of Iridium, which is expected to be completed in mid-2027.

Accordingly, there are or will be important factors that could cause actual results to differ materially from those indicated in such statements and, therefore, you should not place undue reliance on any such statements and caution must be exercised in relying on forward-looking statements.
