In a transformative move for the space industry, Rocket Lab (NASDAQ:RKLB) announced on Monday its acquisition of Iridium Communications (NASDAQ:IRDM) in a deal valued at approximately $8 billion. The transaction adds Iridium's profitable satellite network to Rocket Lab's launch and spacecraft operations, providing a steady stream of subscriber revenue and critical L-band spectrum.
The deal underscores a broader shift in investor sentiment within the space sector. After a rally driven by SpaceX's record IPO earlier this month, market participants are now focusing on fundamental metrics such as backlog, spectrum assets, and recurring cash flows rather than launch schedules alone.
Rocket Lab shares surged 15.9% to $98.01 on Monday, while Iridium jumped 25.4% to $54.59. Other space stocks also rallied: AST SpaceMobile (NASDAQ:ASTS) climbed 21.3% to $86.77, Planet Labs (NYSE:PL) added 15.5% to $31.28, and Viasat (NASDAQ:VSAT) closed up 23.8% at $76.69. SpaceX (NASDAQ:SPCX), which listed this month, rose 7.0% to $164.19.
Deal Details and Strategic Rationale
The Iridium acquisition brings Rocket Lab access to over 2.55 million subscribers and $495 million in 2025 operational EBITDA. Rocket Lab CEO Peter Beck described Iridium as a very profitable business with crucial spectrum assets. Caelus Partners president Micah Walter Range noted the deal provides Rocket Lab with an initial customer base and distribution network, effectively a space business that already invoices customers monthly.
Rocket Lab reported $200.3 million in revenue for the first quarter, up 63.5% year-over-year, with a backlog of $2.2 billion. However, that backlog represents less than 4% of Rocket Lab's $59.3 billion market capitalization as of Monday's close. The company guided Q2 revenue between $225 million and $240 million with an adjusted EBITDA loss of $20 million to $26 million, indicating investors are pricing in future growth from the Neutron rocket and larger spacecraft.
Market Dynamics and Valuation Concerns
Planet Labs reported remaining performance obligations of $816 million and backlog above $906 million, with 99% of annual contract value recurring. CFO Ashley Johnson highlighted the backlog as a source of visibility and predictability. Despite this, Planet's shares trade at roughly 12 times its backlog on market value.
AST SpaceMobile, a pure play on satellite capacity, launched BlueBird 8, 9, and 10 satellites on June 17, with BlueBirds 11-13 expected in early August. The company has nearly 60 mobile network operator partnerships reaching over 3 billion users. However, its 2026 revenue estimate of $150 million to $200 million remains below 1% of its $25.2 billion market cap, though it holds about $3.5 billion in cash and equivalents.
SpaceX set a new bar with the largest U.S. IPO ever, pricing at $135 per share and raising $75 billion, valuing the company at $1.77 trillion. The stock jumped on its first day, while some other space stocks fell as investors rotated capital into SpaceX. Talley Léger, chief market strategist at The Wealth Consulting Group, described this as capital recycling.
Passive fund inflows are expected to provide further support. Nasdaq confirmed SpaceX will join the Nasdaq-100 on July 7, with JPMorgan estimating $4.3 billion in passive inflows tied to the move. However, Morningstar strategist Michael Field called the stock overvalued, a warning that now hangs over smaller space stocks as well.
What Investors Should Watch
The gap between reported revenue and market value remains a key focus. Rocket Lab's backlog-to-market-cap ratio of 3.7% and Planet's 8.4% highlight the premium investors are paying for future growth. AST SpaceMobile's 2026 revenue estimate of $150 million to $200 million against a $25.2 billion market cap underscores the speculative nature of some valuations.
As the June rally pushes space stocks higher, the sector faces increasing pressure to demonstrate that its spectrum, satellites, and contract wins can justify current prices. The Iridium deal provides a template for how established cash flows can anchor valuations in an otherwise high-growth, high-risk industry.
