Iridium Communications Inc. describes progress on its proposed acquisition by Rocket Lab Corporation. Regulatory and licensing filings are underway and are described as proceeding on schedule. The companies are currently targeting a mid-2027 closing, while exploring whether the timetable can be accelerated; until then, it remains business as usual for Iridium.

Early relationship-building has begun, including a two-day visit by Rocket Lab executives to Iridium’s facilities to better understand Iridium’s network, partner-focused business model and growth pillars. Management highlights potential combined opportunities across IoT and NTN Direct, Iridium’s PNT platform (including cybersecurity applications), national security missions, and aviation safety via Aireon and communications services, framing the combination as potentially “1 + 1 = 3.”

Rocket Lab has filed a Registration Statement on Form S-4 that includes Iridium’s proxy statement/prospectus, which is not yet effective. Iridium stockholders will be asked to approve transaction-related proposals, and investors are urged to read the Form S-4 and related proxy statement/prospectus carefully when available, as they will contain important information and risk factors regarding the transaction and its completion.

Rocket Lab Corporation is advancing its proposed acquisition of Iridium Communications Inc. with several regulatory and financing milestones. The U.S. antitrust waiting period under the Hart-Scott-Rodino Act expired at 11:59 p.m. Eastern Time on August 12, 2026. Rocket Lab has filed a Registration Statement on Form S-4 to register securities that will be issued to Iridium shareholders as equity consideration, and Rocket Lab and Iridium have jointly filed FCC applications to transfer control of Iridium’s licenses and authorizations.

To fund the transaction, Rocket Lab has a commitment for a $3.6 billion, 364-day senior secured bridge term loan facility and intends to replace this with a mix of permanent debt and equity. As part of this strategy, Rocket Lab and Iridium plan to seek amendments to Iridium’s existing term loan credit facility, which had $1.775 billion outstanding as of June 30, 2026, so it can remain in place post-closing and reduce required bridge financing, subject to lender consent. Rocket Lab has also established a new at-the-market equity program, carrying forward the unsold amount from its May 2026 program, with proceeds intended to reduce remaining bridge loan commitments.

Silver Heights Capital Management Inc. reported beneficial ownership of 3,274,947 shares of Iridium Communications Inc. common stock, representing 3.1% of the class. Of these shares, 2,484,922 are subject to sole voting and dispositive power and 790,025 are subject to shared voting and dispositive power. The filing confirms that Silver Heights Capital Management Inc. now holds 5 percent or less of this class of securities.

Rocket Lab Corporation outlines a pending acquisition of Iridium Communications, aiming to combine its launch and satellite manufacturing capabilities with Iridium’s global L-band communications constellation. Iridium currently operates 66 satellites, serves more than 2.5 million subscribers, and generated over $870 million in annual revenue in the past year. Management describes this as transforming Rocket Lab into a vertically integrated “space applications” company spanning launch, satellite hardware and services, with a focus on recurring-revenue applications such as IoT, direct-to-device, advanced PNT, defense and national security, and aviation and marine safety. The constellation is described as supportable into 2035, and the transaction is expected to close in mid-2027, subject to Iridium stockholder approval and regulatory review.

Iridium Communications Inc. updated its corporate governance and announced a shareholder cash return. On August 10, 2026, the Board adopted Amended and Restated Bylaws, adding a forum selection provision. This provision designates the Court of Chancery of the State of Delaware (or, if it lacks subject matter jurisdiction, the federal district court in Delaware) as the exclusive forum for specified internal corporate disputes, including certain derivative actions, fiduciary duty claims, and matters governed by Delaware law or the company’s charter or bylaws. It also designates the federal district courts of the United States as the exclusive forum for claims arising under the Securities Act of 1933.

On the same date, the Board declared a cash dividend of $0.15 per share on the company’s common stock, payable on September 30, 2026 to stockholders of record as of September 15, 2026.
