KTOS vs UMAC: Which Is the Better Buy in 2026?

Last updated October 2026

Short answer

KTOS is the larger of the two ($7.58B market cap): the incumbent the market prices for continued execution (36.30x forward earnings, beta 1.11). UMAC is the smaller challenger ($814.79M), priced similarly on forward earnings (-50.44x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.

KTOS vs UMAC: the tie-breaker metrics

Same yardstick, side by side (as of October 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.

Before you buy: how KTOS and UMAC affect your concentration

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.

What does Kratos Defense & Security Solutions (KTOS) do?

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.

KTOS vs UMAC: how do they differ?

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.

Which fits which kind of investor

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 remains the dominant risk even after the 2026 sell-off: at about 238x trailing and 36x forward earnings, the stock still prices in years of sustained growth, and the roughly 49% year-to-date decline shows how sharply it can derate when sentiment on defense and drone names turns. For UMAC, unusual Machines is a small, loss-making company with a short operating history in its current form; revenue is growing fast (about $31.9 million over the trailing twelve months) but from a tiny base, and it has missed EPS estimates in three of the last four quarters.

KTOS or UMAC: which should you pick?

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 vs UMAC: the full fundamentals

KTOS. As of October 2026, Kratos is growing revenue about 30 percent a year while earning only about 2 cents of net income per dollar of sales, so the trailing P/E is in the hundreds and price-to-sales is about 5 times, down from roughly 7 times in the spring after the stock fell about 49 percent. The forward P/E near 36x assumes EPS rises to about $1.11 in 2027. The mean analyst target of about $98 sits far above the current price, while new coverage from Macquarie in October came in at $70.

UMAC. With no earnings to anchor a P/E, UMAC trades on revenue growth and the drone-policy story: about 27x trailing sales and a forward P/E that is negative. The large cash balance lowers near-term funding risk, so the swing factor is whether revenue keeps scaling toward the roughly $56 million consensus expects for 2026.

Headline figures (approximate, October 2026): KTOS shows revenue (q2 2026) ~$459M, up ~30% YoY, revenue (ttm) ~$1.52B, 2026 revenue (analyst consensus) ~$1.79B, net income (ttm) ~$31M (~2% margin); UMAC shows business model Drone components: motors, flight controllers, FPV parts; early moves into counter-drone, revenue (ttm) ~$31.9 million; Q2 2026 ~$16.7 million (up from ~$2.1 million in Q3 2025), margins Gross ~35%, operating ~-47%, net income (ttm) ~-$6.5 million; operating cash flow ~-$56 million.

The bottom line: KTOS vs UMAC

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. Walnut can show your combined KTOS and UMAC exposure against your real portfolio. It is not an investment adviser.

FAQ

What is the difference between KTOS and UMAC?

+

Kratos Defense & Security Solutions (KTOS) is a defense technology company that specializes in affordable, high-performance systems the U.S. 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. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.

Is KTOS or UMAC the better stock?

+

Neither is universally better. KTOS is the larger incumbent; UMAC is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.

Which is cheaper, KTOS or UMAC?

+

On forward P/E (as of October 2026), KTOS trades at 36.30x and UMAC at -50.44x, so UMAC is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.

Should you own both KTOS and UMAC?

+

Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.

What are the risks of KTOS vs UMAC?

+

KTOS: Valuation remains the dominant risk even after the 2026 sell-off: at about 238x trailing and 36x forward earnings, the stock still prices in years of sustained growth, and the roughly 49% year-to-date decline shows how sharply it can derate when sentiment on defense and drone names turns. Kratos depends on U.S. government budgets, appropriations timing and program-of-record decisions, all of which can slip or be cut. Many flagship programs (Valkyrie, hypersonics, the new Indiana facilities) are still scaling, so production, supply-chain and execution risk is real, and heavy capacity spending has pushed free cash flow negative. Competition comes from far larger primes like Lockheed Martin, Boeing, Northrop Grumman and RTX, plus focused drone makers such as Anduril, which can pressure pricing and win rates. Thin operating margins mean profitability remains modest even as revenue grows. UMAC: Unusual Machines is a small, loss-making company with a short operating history in its current form; revenue is growing fast (about $31.9 million over the trailing twelve months) but from a tiny base, and it has missed EPS estimates in three of the last four quarters. It depends on building domestic manufacturing capability that does not yet exist at scale, which is capital-intensive and unproven. It has funded itself through equity issuance, which built a large cash balance (about $316 million) but also expanded the share count. The price has been highly volatile, ranging from about $7 to $35 over the past year and falling about 25% in the past month. At roughly 27x trailing sales, the valuation assumes the ramp continues. This remains a speculative small-cap.
