Firefly Aerospace vs. Redwire: Which Industrials Stock Is a Better Buy for 2027?

The race for space superiority is shifting from government agencies to private innovators. As launch demand surges, choosing between Firefly Aerospace (NASDAQ:FLY)and Redwire (NYSE:RDW)depends on your risk appetite.

Firefly Aerospace focuses on end-to-end space transportation, from rapid-response launches to lunar landers. Redwire provides the critical infrastructure and autonomous systems that keep satellites and missions operational. Both companies represent high-growth opportunities within the evolving landscape of defense stocks.

The case for Firefly Aerospace

Firefly Aerospace provides launch services, lunar landers, and orbital vehicles to a mix of government and commercial clients. Major customers include NASA, the U.S. Space Force, and defense giants like Lockheed Martin (NYSE:LMT) and Northrop Grumman (NYSE:NOC). The company recently expanded its reach by signing a multi-launch agreement with AST SpaceMobile (NASDAQ:ASTS).

In the 12 months ended Sept. 30, 2026, revenue reached nearly $366.9 million. This growth trajectory is paired with a net loss of approximately $324.2 million for the same period. This performance resulted in a net margin, which measures how much of each dollar of revenue becomes profit, of negative 88.4%.

As of its December 2025 balance sheet, the current ratio is close to 4.5x. This metric indicates the company has $4.50 in short-term assets for every $1.00 in liabilities. The debt-to-equity ratio is roughly 0.3x, indicating that total debt is low relative to shareholders' equity. In the fiscal year ended Dec. 31, 2025, free cash flow was negative $237.8 million, representing operating cash minus capital expenditures.

The case for Redwire

Redwire specializes in space infrastructure, including solar arrays, sensors, and autonomous systems. It serves a diverse group of clients, including Eli Lilly (NYSE:LLY) for microgravity research. In its latest annual report, national security customers accounted for nearly 47% of revenue, which adds a layer of risk due to customer concentration.

In the 12 months ended Sept. 30, 2026, revenue reached approximately $431.9 million, representing revenue growth of nearly 45.8%. Despite rising sales, the company reported a net loss of nearly $226.1 million. This produced a net margin of negative 52.4%, showing that the company has not yet reached overall profitability.

As of its December 2025 balance sheet, the debt-to-equity ratio is roughly 0.2x. The current ratio stands at approximately 1.6x, indicating the business has more assets than liabilities due within one year. In the fiscal year ended Dec. 31, 2025, free cash flow was negative $190.8 million, reflecting the cash used to maintain and expand the business.

Risk profile comparison

Firefly Aerospace faces intense competition from established players like Boeing (NYSE:BA) and emerging rivals like Rocket Lab (NASDAQ:RKLB). The company must manage potential delays in the development of its Alpha launch vehicle and fluctuations in U.S. government spending. Relying on the successful integration of its SciTec acquisition also adds execution risk for management.

Redwire faces significant revenue concentration and competition from large aerospace firms such as Northrop Grumman. Operational risks include potential failures in its space systems or reliance on third-party launch providers to get its technology into orbit. Additionally, the company is working to address potential material weaknesses in its internal financial controls.

Valuation comparison

Redwire appears to be the more conservatively valued option based on its lower P/S ratio, which measures market value against sales over the past twelve months.

Valuation metrics include those sourced from Financial Modeling Prep (FMP) and may differ from those of other data providers.

Which stock would I buy for 2027?

When comparing Redwire and Firefly, 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. Over the last three years, Redwire has averaged 27% year-over-year revenue growth. Firefly, on the other hand, has averaged 298% growth. Granted, it has been growing off a smaller revenue base, but its growth is nevertheless eye-popping. That gives Firefly an edge in this category.

Another factor to consider is each company's profitability. Both companies remain firmly in the growth stage of their lifecycles. Neither is yet consistently profitable. However, Redwire, with an operating margin of -37%, appears closer to profitability than Firefly, with an operating margin of -102%. That gives Redwire a slight edge in this category.

Finally, there's valuation. Since neither company is profitable, we should evaluate these two stocks' valuation on a price-to-sales (P/S) basis. Redwire stock is more affordable with a P/S ratio of 3.7x, while Firefly's 11.1x multiple is significantly higher.

To sum up, both companies are space stocks worth considering, yet they serve different segments of the space industry and may appeal to different investors. Given its incredible revenue growth, Firefly will be the favorite for hypergrowth investors. However, investors shouldn't overlook Redwire. It has solid revenue growth, appears closer to profitability, and has a more modest valuation. To me, that gives it the edge in a head-to-head matchup.
