Rocket Lab Falls 6% as SpaceX Flags Iridium Deal to the FCC, Intuitive Machines Slides 5%

SpaceX just filed a complaint at the FCC that ties regulatory pressure directly into Rocket Lab's share price through a deal structure few investors have fully mapped out.

Regulatory friction at the Federal Communications Commission is turning a merger question into a share-price story, with SpaceX challenging Iridium Communications (NASDAQ:IRDM | IRDM Price Prediction) conduct as the agency reviews Rocket Lab’s (NASDAQ:RKLB) pending $8 billion takeover. The complaint hits Rocket Lab directly because the deal consideration ties Iridium payouts to Rocket Lab’s own share price near closing.

Rocket Lab stock is down 6% to $63.82, extending a rough week for the launch and space systems name. Rocket Lab stock was down 3% year to date (YTD) through Thursday’s close.

Notably, Intuitive Machines (NASDAQ:LUNR) stock is down 5% to $15.32 alongside the broader space complex. Intuitive Machines stock was up 31% over the past month heading into Friday, so today’s slide walks back only a slice of that run.

SpaceX Takes the Fight to the FCC

SpaceX asked the Federal Communications Commission on Thursday to examine Iridium’s conduct while the agency reviews applications tied to Rocket Lab’s proposed acquisition. SpaceX satellite policy associate Matthew Turk asserted that “Iridium’s well-documented history of anticompetitive attacks against its competitors and American consumers hangs as a cloud over the proposed transaction.”

Turk stated that “SpaceX does not oppose the transaction,” adding that “the Commission should carefully evaluate whether Iridium’s conduct is in the public interest.” Turk also mentioned that Iridium had filed more than 50 petitions over eight months seeking to block or restrict rival satellite deployments.

The underlying dispute involves SpaceX’s next-generation Starlink gateways, which can support gigabit-speed service. Iridium has argued that some proposed ground stations could interfere with its operations because the companies share portions of the 19.4 to 19.6 GHz and 29.1 to 29.3 GHz spectrum bands, and that several gateways could exceed permissible interference levels “by a wide margin.”

Why the Deal Structure Amplifies the Risk

Iridium issued its definitive proxy this week and Rocket Lab its prospectus, sending the merger to a shareholder vote on September 24. Each Iridium share would convert into $27 in cash plus a variable number of Rocket Lab shares based on Rocket Lab’s 10-day volume-weighted average price shortly before closing.

The variable exchange ratio is the analytical crux for Rocket Lab shareholders. Because Iridium holders receive a variable number of Rocket Lab shares set by Rocket Lab’s own average price near closing, regulatory delay and Rocket Lab share weakness feed each other. That mechanic is why merger-arbitrage positioning has been disrupted and why regulatory noise transmits directly into Rocket Lab stock rather than staying contained in Iridium.

The transaction initially implied an equity value of $6 billion and an enterprise value of $8.1 billion, with former Iridium shareholders expected to own 5% of the combined company. Rocket Lab has secured a $3.6 billion bridge facility it may replace with longer-term debt, equity financing, or both.

Space Names Slide With the Sector

The Procure Space ETF (NASDAQ:UFO) is down 2% to $43.92, giving up ground as its top space-focused holdings weaken together. Meanwhile, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is down 0.3% to $768.84, showing that the broad market is quiet while the space complex takes the hit.

Additionally, AST SpaceMobile (NASDAQ:ASTS) stock is down 6% to $58.04, moving with the sector rather than any verified company-specific news. AST SpaceMobile stock was down 15% year over year (YoY) through Thursday’s close.

No company announcement, filing, contract, or analyst action has been verified at Intuitive Machines or AST SpaceMobile today. Both are trading with a space complex that is broadly lower, and neither move should be extended into confirmation of the Rocket Lab catalyst.

What to Watch Next

Separately on Neutron, Rocket Lab said it completed checkouts of the reusable Hungry Hippo fairing, which endured 275,000 pounds of force during qualification testing, with control-surface hubs tested beyond 125% of projected flight loads. CEO Peter Beck has cautioned that “the window for an end-of-year launch is narrowing.”

Retail sentiment on Rocket Lab is divided, with some traders treating the regulatory issue as a serious threat to the deal and others treating the weakness as a buying opportunity. Dilution from at-the-market share issuance and Neutron timing remain live parts of that debate, and neither camp has a clean data point in its favor today.

Investors should keep their Rocket Lab exposure sized modestly into the September 24 shareholder vote, given how directly regulatory noise now transmits into the stock through the variable exchange ratio. Traders can watch for any Rocket Lab response at the FCC and for coordination language from Iridium that might narrow the interference dispute before the vote.
