Massive engine orders meet ongoing cash and currency headwinds
- Kratos is growing quickly as defense buyers demand lower-cost drones, hypersonic test systems, and mass munitions.
- The company plans to produce 3,000 Spartan turbojet engines in 2027 and another 5,000 in 2028.
- Operating cash flow was negative $11 million in the second quarter of 2026 because Kratos bought inventory ahead of production.
- A strong Israeli shekel is creating an expected $5 million to $7 million headwind to full-year earnings.
- The stock needs proof that massive volume orders can eventually generate consistent cash flow.
Volume is exploding, but cash flow remains delayed
Kratos is entering a major production phase. Management expects to build 3,000 Spartan turbojet engines in 2027 and an additional 5,000 in 2028. Visibility into hypersonics is also increasing, backed by new Kraken and Nemesis awards alongside significant funding for the MACH-TB program.
The bull case is that Kratos is cementing its position as the preferred merchant supplier for low-cost engines and mass munitions. With a $700 million hypersonics revenue target for 2027, the company has a clear runway for high organic growth.
The bear case focuses on cash burn and new margin pressures. Operating cash flow was negative $11 million in the second quarter of 2026 because Kratos is funding working capital and supply chain preparations. The company also faces a $5 million to $7 million headwind to full-year earnings from a strong Israeli shekel.
Finn scores remain cautious. While growth is strong, performance, valuation, and financial health scores reflect the tension between top-line expansion and capital consumption. Investors are waiting for the growing backlog to generate positive operating cash flow.
Build first, sell into defense demand
Kratos makes money by selling defense products, systems, software, and services to U.S. defense and national security customers. It works both as a prime contractor and as a supplier to larger defense companies.
The company frequently spends its own money on research, development, facilities, and product design before a program fully ramps. Its core idea is that affordability is a technology. Kratos tries to build useful weapons and defense systems faster and cheaper than traditional programs.
That model can create major upside when a product wins. It can also use a lot of cash before the payoff arrives. The current backlog supports growth, but the company must buy parts, fund production, and handle fixed-price cost pressure before investors see steady free cash flow.
Drones, rockets, space, and propulsion
Unmanned systems
This includes jet-powered drone aircraft such as Valkyrie, Mako, and Thanatos. Unmanned Systems revenue grew 8.1% organically in the second quarter of 2026.
Rocket and hypersonic systems
Kratos builds hypersonic vehicles, ballistic missile targets, and Zeus solid rocket motors. The portfolio now includes new awards like Kraken 1, Kraken 2, and Nemesis.
Space and satellite systems
Kratos sells virtualized satellite ground systems, command and control software, and telemetry tools. A $447 million Space Force award makes this area highly important to the thesis.
C5ISR systems
C5ISR means command, control, communications, computing, combat, intelligence, surveillance, and reconnaissance. These systems help military customers collect, move, and use information.
Microwave electronics
These products support missiles, radar, air defense, and satellite communications. The Israeli division faces near-term margin pressure from currency rates.
Training systems
Kratos provides virtual and augmented reality training tools for military users. This adds breadth to the government solutions segment.
Directed energy weapons
Kratos secured a multi-hundred million dollar directed energy weapon system program as prime contractor. Margin and cash details are still emerging.
Propulsion systems
Kratos is scaling production of small TDI Spartan turbojet engines, planning 3,000 units in 2027 and 5,000 in 2028. This rapid scale supports low-cost cruise missiles and mass munitions.
Two segments, one larger base
Segment mix is from early 2026 revenue. Kratos Government Solutions is the larger segment, while Unmanned Systems is smaller but tied closely to the drone growth story.
What could break the thesis
Cash burn during the ramp
High impact · High oddsKratos used $11 million of cash in operating activities in the second quarter of 2026. Management links the burn to inventory and prepayments needed for booked growth. Investors need to see cash come back as revenue is billed and collected.
Engine supply chain strain
High impact · Medium oddsBuilding 3,000 turbojet engines in 2027 and 5,000 in 2028 requires massive coordination. Any bottleneck in the supply chain for these engines or solid rocket motors could delay shipments and hurt revenue.
Currency headwinds in Israel
Medium impact · High oddsThe company's microwave electronics business in Israel is being squeezed by a strong shekel. Because Kratos is paid in dollars but pays staff in shekels, this is creating a direct hit to earnings.
Margins stay too low
High impact · Medium oddsGross margin was 24.2% in the first quarter of 2026. If new work grows revenue but carries weak margins due to fixed-price limits, the backlog will not be worth as much as it looks.
Federal budget and shutdown risk
Medium impact · Medium oddsKratos depends heavily on U.S. government defense spending. An extended federal government shutdown could materially affect business, cash flow, and financial condition by delaying contract awards and payments.
In one breath
What does Kratos Defense do?
Kratos builds defense technology for U.S. national security customers. Its main areas include drones, hypersonic systems, satellite ground software, missile electronics, propulsion engines, and directed energy weapons.
Why is KTOS growing?
Growth is driven by propulsion engines, hypersonics, Valkyrie aircraft, and space programs. In the second quarter of 2026, the Kratos Government Solutions segment posted 22% organic revenue growth.
What is the biggest concern for KTOS stock?
The biggest concern is cash conversion. Kratos has a massive backlog, but operating cash flow remains negative because the company must fund working capital and engine parts before collections arrive.
Is Kratos a drone company?
Drones are important, but Kratos is broader than drones. In early 2026, Unmanned Systems was about 22% of revenue, while Kratos Government Solutions made up the rest.
