Space exploration stocks are drawing renewed attention after Space Exploration Technologies’ initial public offering, with investors looking to other ways to gain exposure to rockets and satellite communications. Rocket Lab has emerged as a key name for investors tracking the sector, supported by a growing backlog, new launch contracts and expanding defense-related activity, according to company disclosures.
While SpaceX’s move into public markets may keep the spotlight on the broader industry, Rocket Lab’s strategy hinges on scaling Electron and progressing Neutron, alongside a potential shift toward satellite operations and communications services through a planned acquisition.
Key takeaways
- Price move: The article does not provide a specific share-price change for Rocket Lab or broader space stocks.
- Catalyst: Investor focus is intensifying after SpaceX’s IPO, while Rocket Lab is separately supported by backlog growth and multiple contract wins, including defense-linked launches.
- Key implication: Rocket Lab’s near-term momentum appears tied to execution on existing vehicles, but the longer-term growth profile may broaden if an acquisition expands it from launching satellites to operating them.
- Risk watch: The company remains unprofitable, and the planned first launch timeline for its Neutron rocket has shifted after a development setback.
What’s driving attention in the space sector
SpaceX’s IPO has increased public-market interest in space-related equities, encouraging investors to reassess demand for launch services and satellite communications. The immediate index-tracking angle is also a factor: SpaceX is set to join the Nasdaq-100 on July 7, which could prompt purchases by funds that track the index. The article notes that the initial index weight for SpaceX is estimated at less than 1% once the Nasdaq-100 adjusts for public float.
However, the focus on Rocket Lab is grounded in operating developments rather than relying only on industry excitement. The company’s reported figures for the first quarter point to continued commercial and government demand, with backlog rising sequentially and contract activity expanding across both launch platforms and defense-oriented programs.
Rocket Lab’s momentum: revenue, margins and backlog
According to the company’s first-quarter results, Rocket Lab revenue increased 63.5% year over year to $200.3 million. The firm reported GAAP gross margin of 38.2%, and it said backlog increased 20.2% sequentially to $2.2 billion.
The company also described a steady flow of new orders. Rocket Lab signed 31 new contracts for Electron, its small rocket, and HASTE, a defense-focused launch vehicle used for hypersonic testing. It added five contracts for Neutron, its larger rocket, which is still under development. Rocket Lab said it had more than 70 contracted launches in its backlog at the end of the first quarter.
For the second quarter, Rocket Lab expects revenue to fall in the range of $225 million to $240 million, up 16% sequentially at the midpoint, as reported in the article.
From launches to operations: Iridium deal and defense expansion
The article points to two longer-term catalysts that could expand Rocket Lab’s role in the space ecosystem. First, Rocket Lab is planning an $8 billion acquisition of Iridium Communications. If the deal closes, the company would shift from being primarily a launch provider to also operating satellites and selling communications services, according to the article’s description.
Iridium already operates a low-Earth-orbit satellite network, and the article notes it serves more than 2.5 million subscribers across government, aviation, maritime, defense and enterprise markets. The acquisition would potentially increase Rocket Lab’s addressable market by combining launch capabilities with downstream communications revenue, though timing and deal completion remain key unknowns for investors.
Second, Rocket Lab is building out a defense business alongside commercial launches. In March 2026, the company signed a $190 million HASTE contract with Kratos Defense & Security Solutions for the U.S. Department of Defense’s MACH-TB 2.0 hypersonic testing program. The article states the contract covers 20 hypersonic test flights over four years and would be Rocket Lab’s largest launch contract in its history. That emphasis on defense-linked launches can help diversify revenue sources and reduce reliance on a single customer segment.
Key risks investors are monitoring
Despite the backlog and contract activity, the article highlights several areas investors should monitor closely. The Neutron rocket is central to Rocket Lab’s plan to support larger satellites and government missions, but the company pushed back its first launch target to the fourth quarter of 2026 after a development setback. Further slippage would likely affect investor confidence in execution.
Rocket Lab also remains unprofitable. The company reported a net loss of $45 million in the first quarter and expects an adjusted EBITDA loss of $20 million to $26 million in the second quarter, as cited in the article.
Customer concentration is another concern. The article states that in 2025 the company’s top five customers accounted for 49% of revenue, while the top five backlog customers represented 77% of backlog. It also notes that 47% of revenue came from U.S. government-related contracts in 2025, many of which were fixed-price arrangements—an exposure that can be sensitive to program schedules and cost control.
Bigger picture: execution will determine whether hype converts to returns
With SpaceX’s IPO pulling investor attention toward space equities, Rocket Lab may benefit from industry-level flows. But the company’s fundamentals—backlog growth, contract wins and progress across Electron, HASTE and Neutron—will likely be the differentiators for investors deciding how much weight to assign to the next phase of space commercialization. In the near term, Rocket Lab’s delivery on guidance, progress toward Neutron’s revised timeline and developments on the proposed Iridium acquisition will be the key items to watch.
