AVEX vs KTOS: How AEVEX Corp. and Kratos Defense & Security Solutions Compare (2026)

Same yardstick, side by side (as of August 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. AVEX and KTOS 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 AVEX and KTOS 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.

AEVEX Corp. was founded in 2017 and runs two segments. Tactical Systems designs and builds attritable unmanned systems: the Phoenix Ghost loitering munition family (including the Disruptor and Dominator variants first revealed publicly when the Pentagon sent 121 units to Ukraine in April 2022), plus the Mako unmanned surface vessel shown at the Special Operations Forces trade show in May 2026, which the company rates at up to 50 knots. Global Solutions is the services half: airborne ISR, processing and exploitation of collected imagery, and in-theater manufacturing and sustainment close to the units using the hardware. Roughly ~78% of revenue comes from government customers, the company employs about ~650 people, and it says it has more than ~10,200 systems committed through the end of 2026.

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.

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

• AVEX drivers: One-way attack drone procurement moving from experiment to program of record; Attritable economics fit the way the US now plans to fight.
• KTOS drivers: Valkyrie and collaborative combat aircraft; Hypersonics, rockets and engines.

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: Customer concentration is the dominant exposure: roughly ~78% of revenue comes from government buyers, so a continuing resolution, a program cancellation or a reprioritization inside the unmanned systems budget can move a full year of results. For KTOS, 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.

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 AVEX if you believe its drivers more; KTOS 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 AVEX and KTOS guides.

AVEX. AEVEX is profitable, which distinguishes it from most drone-adjacent listings, but the earnings base is thin relative to the market value, so the multiple carries the story. First quarter 2026 revenue of ~$216.7 million against ~$53.3 million a year earlier is not a like-for-like organic comparison, and the pre-IPO reporting history is short. The August 12, 2026 second quarter release is the first clean read on margin progression as a public company.

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.

Headline figures (approximate, August 2026): AVEX shows revenue (ttm) ~$596 million, up ~10.4% year over year, net income (ttm) ~$29.6 million, or ~$0.33 per share, market capitalization ~$2.5 billion on ~114 million shares, p/e ratio (trailing) ~67x at a share price near ~$22; KTOS shows revenue (q1 2026) ~$371M, revenue (ttm) ~$1.4B, fy2026 revenue guidance ~$1.7B to $1.76B, adjusted ebitda (fy2025) ~$120M.

AVEX and KTOS 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.
