Rocket Lab Corp

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.
