Which of these aerospace innovators is the better choice for your long-term portfolio in 2026?
The space economy is no longer a distant dream, and investors are looking for the best way to gain exposure. Should you bet on Redwire (NYSE:RDW) or Rocket Lab (NASDAQ:RKLB)?
Redwire focuses on providing specialized components and infrastructure, while Rocket Lab offers full-service launch capabilities and satellite manufacturing. Both companies play vital roles in the growing space industry, but they follow distinct paths to scale their operations and achieve profitability for their shareholders.
Redwire provides mission-critical space infrastructure for civil, national security, and commercial customers. As a prominent name among defense stocks, it supplies technology for the U.S. Space Force and NASA. Its major customers include agencies like DARPA and commercial giants such as Bristol Myers Squibb. In 2026, the company entered a partnership with Honda's space development division to further expand its reach.
In FY 2025, revenue reached nearly $335.4 million, representing growth of approximately 10.3% compared to the prior year. Despite this top-line expansion, the company reported a net loss of roughly $226.6 million for the period. This compares to a net loss of nearly $114.3 million in the previous year. Redwire is often assessed using its P/S ratio, which measures its market value against sales over the past twelve months.
As of its December 2025 balance sheet, the debt-to-equity ratio was nearly 0.2x. This ratio, which compares total debt to shareholder equity, suggests a conservative level of leverage. The current ratio of approximately 1.6x indicates the company has $1.60 in short-term assets for every $1.00 in current liabilities. Free cash flow, which equals cash flow from operations minus capital expenditures, was a loss of nearly $190.8 million in FY 2025.
Rocket Lab is an end-to-end space company providing launch services and satellite components. Its Electron rocket is a leading small-satellite launcher, while the Neutron vehicle is under development for larger missions. The company is currently in the process of acquiring Iridium Communications (NASDAQ:IRDM), a transaction approved by shareholders in late 2026. This acquisition is expected to significantly enhance its space systems segment.
In FY 2025, revenue reached approximately $601.8 million, showing strong growth of nearly 38% over the previous fiscal year. The company reported a net loss of roughly $198.2 million for the period, which is a slight increase from the $190.2 million loss in the prior year. While the company is not yet profitable, its net margin improved from -43.6% to approximately -32.9% during this time.
Based on its December 2025 balance sheet, the debt-to-equity ratio of nearly 0.1x indicates very low debt relative to equity. The current ratio is roughly 4.1x, showing a high ability to cover short-term obligations with existing assets. Free cash flow was a loss of roughly $321.8 million for the fiscal year ended Dec. 31, 2025. This reflects ongoing investments in developing the Neutron rocket and satellite infrastructure.
Redwire faces significant competition from large defense contractors like Lockheed Martin (NYSE:LMT) and Northrop Grumman (NYSE:NOC), which puts pressure on its net margin. Revenue concentration is also a major factor, as two customers accounted for roughly 39% of total revenue in 2025. Customer concentration like this adds a layer of risk to the business if contracts are lost or delayed. The company also relies on U.S. government contract funding and complex facility security clearances. A shareholder derivative lawsuit regarding governance has reached a preliminary settlement, with corporate governance reforms currently pending final court approval.
Rocket Lab is navigating risks related to the development and commercialization of its Neutron launch vehicle. The company currently maintains a history of net losses and expects operating expenses to increase as it scales. There is high dependency on the Electron launch vehicle, and manufacturing delays or launch failures could disrupt operations. The pending acquisition of Iridium Communications involves substantial financing and potential shareholder dilution. Additionally, the company faces exposure to foreign exchange fluctuations due to its New Zealand operations and strict regulatory controls for government launch certifications.
Rocket Lab appears more expensive than Redwire based on its Forward P/E ratio, which compares the stock price to future earnings estimates.
| Metric | Redwire | Rocket Lab |
|---|---|---|
| Forward P/E | n/a | 250.6x |
| P/S ratio | 5.7x | 54.1x |

When comparing Redwire and Rocket Lab, investors should consider a few key factors. Let's have a look at them and see what that tells us about each stock.
Firstly, we should consider revenue growth. In truth, both companies have delivered exceptional revenue growth. The space and launch economy remains in its early stages, meaning both companies are ramping their revenues at impressive rates. That said, Rocket Lab can claim the edge in average growth. Over the last three years, the company has averaged 55% quarterly year-over-year revenue growth, while Redwire has averaged 29%. However, in recent quarters, Redwire's growth has overtaken Rocket Lab, with Redwire's revenue growth in its most recent quarter reaching nearly 90%.
Another factor to consider is each company's balance sheet. Both companies remain well capitalized. Rocket Lab has over $2.2 billion in net cash (cash minus debt), while Redwire has approximately $0.5 billion in net cash. That gives each company ample breathing room, considering their respective cash burn rates. Redwire's free cash flow was about -$107 million over the last 12 months, while Rocket Lab's was around -$371 million. If those numbers were to hold, that gives Redwire about 5 years of a cash runway and Rocket Lab about 8 years of one.
Finally, there's valuation. Let's examine the price-to-sales (P/S) ratio, as neither company is reliably profitable at this stage in its lifecycle. With a P/S ratio of 6x, Redwire is far more affordable than Rocket Lab, which has a P/S ratio of 54x.
To sum up, both stocks are compelling choices for growth-oriented investors interested in the emerging space infrastructure and space launch economy. Indeed, given its more reasonable valuation and rapidly expanding revenue, Redwire stock may be a more suitable selection for many growth-oriented investors.
