Rocket Lab Clears a Major Hurdle on the Iridium Acquisition
Rocket Lab (RKLB) said the Hart-Scott-Rodino waiting period for its proposed acquisition of Iridium Communications (IRDM) expired, clearing US antitrust review. Rocket Lab plans to fund the deal with a $3.6 billion 364-day bridge loan from Deutsche Bank and Wells Fargo, then replace it with permanent debt and equity, including a $1.94 billion at-the-market equity distribution. No assurance lender consents will be granted.
How this was made

The 30-second read
Why it matters
HSR expiration clears a key US antitrust hurdle, lowering regulatory uncertainty. However, the financing structure depends on lender consents to keep Iridium’s existing term loan facility in place and on replacing the bridge with permanent capital.
Market read
Traders can reassess deal-risk pricing after a specific regulatory milestone and update expectations around financing execution and closing probability.
What to watch
The equity distribution agreement is not conditional on closing, but the article notes there is no assurance lender consents come through, which can reintroduce deal risk.
Background
Rocket Lab is pursuing the acquisition of Iridium Communications and is using a bridge loan plus a planned replacement of permanent debt and equity.
Ticker impact
Rocket Lab said the HSR waiting period for its Iridium acquisition expired, clearing US antitrust review and advancing deal execution.
Near-term bias to stabilize or rebound versus premarket weakness, with follow-through dependent on lender consents and closing timeline.
The article discloses a concrete regulatory milestone (HSR expiration) plus specific financing mechanics (bridge loan, potential replacement, and lender consents), which can move risk pricing even without final closing.
Market effects
Supports sentiment for space and satellite communications M&A by showing antitrust clearance can be achieved without delay.
US-focused antitrust milestone may reduce uncertainty for US-listed space/defense and satellite-adjacent names.
Iridium is global; deal progress can affect competitive dynamics in satellite communications, though the article is US-antitrust specific.
Counterpoint
HSR expiration may already be partially priced, and the bigger swing factor is whether lender consents and financing replacement terms are secured before closing.
