KTOS vs UMAC: How Kratos Defense & Security Solutions and Unusual Machines Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. KTOS and UMAC share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined KTOS and UMAC exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Kratos Defense & Security Solutions (KTOS) is a defense technology company that specializes in affordable, high-performance systems the U.S. military wants to buy in volume. Its two segments are Unmanned Systems, home to the XQ-58 Valkyrie collaborative combat aircraft and other tactical drones and target drones, and Kratos Government Solutions, which spans hypersonic systems (Erinyes, Dark Fury), solid rocket motors, turbine and jet engines, microwave electronics, C5ISR, space, training and cyber. The common thread is being the low-cost, fast-to-field alternative to legacy prime contractors, which lines up with Pentagon demand for attritable, mass-producible hardware.

Unusual Machines makes drone components and consumer drone products, focusing on domestically manufactured motors, flight controllers and first-person-view parts intended to supply US drone builders.

Full UMAC guide

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• KTOS drivers: Valkyrie and collaborative combat aircraft; Hypersonics, rockets and engines.
• UMAC drivers: Component supply rather than finished aircraft; Domestic sourcing requirements.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Valuation is the dominant risk: with a triple-digit price-to-earnings ratio, the stock prices in years of sustained growth and any stumble can drive a sharp derating. For UMAC, unusual Machines is a very small, loss-making company with limited revenue and a short operating history in its current form.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick KTOS if you believe its drivers more; UMAC if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the KTOS and UMAC guides.

KTOS. As of the March 2026 quarter, Kratos posted about $371 million in Q1 revenue, up roughly 23 percent year over year, and raised full-year 2026 guidance toward $1.7 to $1.76 billion. Net income remains small, so with a market cap around $10 billion the price-to-earnings ratio sits in the hundreds and price-to-sales is roughly 7 times. The valuation reflects growth and backlog expectations far more than current earnings.

UMAC. Unusual Machines is an early-stage supplier whose case rests on policy-driven demand for domestic drone components rather than on current financial performance. Verify the current cash position, revenue and share count.

Headline figures (approximate, MARCH 2026): KTOS shows revenue (q1 2026) ~$371M, revenue (ttm) ~$1.4B, fy2026 revenue guidance ~$1.7B to $1.76B, adjusted ebitda (fy2025) ~$120M; UMAC shows business model Drone components: motors, flight controllers, FPV parts, scale Micro-cap, early revenue; verify current figures, thesis driver US restrictions on Chinese drone components, profitability Loss-making; verify cash runway.

KTOS and UMAC are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
