Rocket Lab Corp Announces Financing Updates for Iridium Acquisition

What Happened

• On September 15, 2026, Rocket Lab Corporation filed an 8‑K and issued a press release (Exhibit 99.1) detailing financing developments for its previously announced pending acquisition of Iridium Communications Inc. Rocket Lab and certain Iridium lenders signed Consent and Amendment No. 4 to Iridium’s Amended and Restated Credit Agreement, addressing how the merger will be treated under that loan agreement and adding a downstream guarantee by Rocket Lab USA, Inc. upon closing. Rocket Lab also formally terminated a previously announced $3.6 billion 364‑day senior secured bridge debt commitment on September 15, 2026. As of that date Rocket Lab had raised approximately $1.944 billion in gross proceeds from its “at‑the‑market” (ATM) equity program (about 29.3 million shares).

Key Details

• Date: September 15, 2026 (filing and press release).
• Credit amendment: Consent & Amendment No. 4 confirms the Transaction will not be a Change of Control under the Amended Iridium Credit Agreement and permits existing term loans to remain outstanding after closing.
• Cost and terms changes effective upon closing: interest on term loans will be SOFR + 2.50%–3.00% (or base rate + 1.50%–2.00%) depending on credit ratings; a 1.00% exit fee (after one year) and a 1.00% prepayment premium for certain repricings.
• Financing mix: ATM equity sales raised ~$1.944B gross (≈29.3M shares); bridge commitment ($3.6B) was terminated prior to the credit amendment taking effect; $1.775B of term loans under the Amended Iridium Credit Agreement will be available upon closing.

Why It Matters

• These actions address how the Iridium acquisition will be financed and reduce Rocket Lab’s reliance on a large bridge loan by combining ATM equity proceeds and committed term loans under the amended Iridium credit facility. For investors, that means a clearer financing plan for the deal and reduced near‑term borrowing commitments from the terminated bridge facility.
• However, some loan terms will become more expensive after closing (higher interest margins and potential fees), and Rocket Lab USA, Inc. will provide a downstream guarantee of the debt upon closing—both factual changes that affect contractual obligations post‑transaction.
• The transaction and the amended financing remain subject to closing conditions, regulatory and stockholder approvals, and other risks described in the S‑4 / definitive proxy statement filed August 26, 2026.
