How is Rocket Lab paying for the Iridium acquisition?

Rocket Lab is funding the cash consideration with proceeds from the completed ATM equity program ($1.944 billion gross from about 29.3 million shares), the amended $1.775 billion Iridium term loan that will remain in place after closing, and other available cash and liquidity. Management states these sources are sufficient to cover the required cash payments, related debt repayments, and fees at closing.

Does the bridge loan still exist?

No. The $3.6 billion 364-day bridge commitment from Deutsche Bank and Wells Fargo was reduced automatically by the ATM proceeds and the Iridium term loan availability, and it was formally terminated in full on September 15, 2026, before Consent and Amendment No. 4 became effective.

What does the Change of Control amendment mean for Iridium's debt?

The amendment carves out Rocket Lab's acquisition from the change-of-control definition, so the Iridium term loans do not need to be refinanced or repaid at closing. The loans can stay outstanding, supported by a downstream guarantee from Rocket Lab USA, Inc. at closing, and certain pricing and fee terms take effect only after the deal closes.

How much more will the debt cost after the deal closes?

After closing, the term loans reprice to SOFR plus 2.50%-3.00% or base rate plus 1.50%-2.00%, depending on Rocket Lab's credit ratings. Additionally, a 1.00% exit fee applies to prepayments made after the first anniversary of closing. The filing does not disclose the current or expected all-in interest rate, so investors should evaluate the spread increase against Rocket Lab's rating outlook.

What is the dilution impact of the ATM program?

The ATM program issued approximately 29.3 million shares. The filing does not state Rocket Lab's total share count before or after the offering, so the exact percentage dilution cannot be calculated from this document alone. Investors should check the company's most recent quarterly report or prospectus for the basic share count to assess the impact.

RKLB 8-K: Regulation FD

01—Abstract

Summary

Summary of the 8-K filed September 15, 2026. Cited figures are marked; the original filing is the authoritative source.

Rocket Lab (RKLB) reported on September 15, 2026 that it has fully funded its pending acquisition of Iridium Communications.

The company completed its at-the-market (ATM) equity program, raising approximately $1.944 billion^a in gross proceeds from the sale of about 29.3 million shares before commissions and expenses. Management says these proceeds, together with the amended Iridium credit facility and other available liquidity, are sufficient to cover the anticipated cash consideration and related payments at closing. The company expects the transaction to close in mid-2027, subject to regulatory approvals and stockholder approval of the Iridium holders.

On the debt side, Iridium and its lenders (at least the Required Lenders) signed Consent and Amendment No. 4 to the existing $1.775 billion^b term loan. The amendment carves the Transaction out of the change-of-control definition, so the loans can remain outstanding after closing, and it adds a downstream unsecured guarantee from Rocket Lab USA, Inc. at closing. Post-closing pricing steps up to SOFR plus 2.50%-3.00% (or base rate plus 1.50%-2.00%) based on Rocket Lab's credit ratings, and a 1.00% exit fee applies to prepayments after the first anniversary of closing.

The $3.6 billion^c 364-day bridge commitment was terminated in full, removing a bridge-financing overhang. For investors, the key takeaways are reduced financing risk and a clearer capital structure, offset by meaningful dilution from the ATM issuance and a higher cost of the permanent Iridium debt once the deal closes. The filing does not disclose Iridium's or Rocket Lab's standalone financial results, purchase price breakdown, or pro forma leverage, so those figures should be sought in the S-4/final prospectus.
