The spread is tied to the deal math. Iridium holders would receive $27—paid in cash and Rocket Lab shares. The share count depends on Rocket Lab’s 10-day VWAP before close. If VWAP stays from $67.50 to $112.50, the ratio is $27 divided by VWAP. If VWAP falls under $67.50, Iridium holders get 0.4000 Rocket Lab shares. At $112.50 or higher, it is set at 0.2400.
| Metric | Calculation | Value |
|---|---|---|
| Acquisition offer price | Deal stated at | $54.00 per IRDM share |
| Pre-market IRDM spread | $54.00 minus $52.56 | $1.44 |
| Spread as percent of offer | $1.44 divided by $54.00 | 2.7% |
| RKLB ratio if VWAP is $93.32 | $27.00 over $93.32 | 0.2893 RKLB share |
| Deal enterprise value to 2025 Iridium revenue | $8.0 billion over $871.7 million | 9.2x |
| Deal enterprise value to 2025 Iridium OEBITDA | $8.0 billion against $495 million | 16.2x |
Iridium holders now have more to watch than just satellite revenue or new subscribers. The shares are also moving on how likely the deal is to close, and on Rocket Lab’s share price when things wrap up. The filing says Rocket Lab’s stock price for the exchange ratio is based on the 10-day VWAP ending two trading days before the first merger is effective.
Closing isn’t quick here. The companies said they see the deal wrapping up around mid-2027. The filing lists Iridium holder approval, the Hart-Scott-Rodino wait, FCC signoff on telecom license transfers, more satellite or telecom signoffs from foreign regulators, and the Rocket Lab S-4 registration going effective.
The deal includes a $223.62 million breakup fee Iridium would owe in some situations. Iridium board members holding roughly 1.6% of shares have said they’ll back the merger and oppose any rival bids.
Rocket Lab secured $3.6 billion in 364-day senior secured bridge loan commitments from Deutsche Bank and Wells Fargo. The company said some of the funding will use cash on hand and other debt and equity options. How Rocket Lab puts the deal together could affect its stock price, and that stock makes up half the stated payout for Iridium holders.
Rocket Lab is buying a business that’s generating cash. Iridium booked $871.7 million in revenue and $495 million in EBITDA for 2025, putting its margin at 57%. For 2026’s first quarter, Iridium had $219.1 million in revenue and $158 million in service revenue, which made up 72% of the total.
Rocket Lab CEO Sir Peter Beck called Iridium the “gold standard” for secure satellite connectivity. Iridium’s Matt Desch, who is CEO, said it will come down to how fast new innovations can get to space.
Rocket Lab’s Form S-4 and Iridium’s proxy statement/prospectus are the next filings to watch. The companies said Iridium stockholders will get those documents after they’re finished.
