AVAV vs KRMN: Which Is the Better Buy in 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.

Reading it: AVAV is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

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. AVAV and KRMN 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 AVAV and KRMN 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.

AeroVironment (AVAV) is a defense technology company specializing in unmanned and autonomous systems. It is best known for small, man-portable drones used by militaries for reconnaissance and surveillance, and for loitering munitions, notably the Switchblade family, which are precision-strike drones that have drawn significant attention from conflicts and rising global demand. AeroVironment also builds larger unmanned aircraft systems, uncrewed ground robots, and develops autonomy software and counter-drone solutions. Its primary customer is the US Department of Defense, with growing international and allied-government sales. The company has expanded through acquisitions into adjacent areas such as space, loitering munitions, and autonomy. The investment story centers on the structural growth of drones and autonomous systems in modern warfare, where small, attritable, intelligent systems are reshaping how militaries operate. Founded in 1971 and historically associated with pioneering work in efficient flight, AeroVironment is headquartered in Arlington, Virginia, and is a mid-cap defense growth company tied closely to defense budgets and procurement.

Karman Holdings, which operates as Karman Space & Defense, is a Huntington Beach, California maker of highly engineered systems that go inside missiles, missile-defense interceptors, hypersonic vehicles, unmanned aircraft, and space launch vehicles. Its products fall into three families: payload protection and deployment systems (such as fairings and shrouds), propulsion systems, and aerodynamic interstage structures. It sells into three end markets, Hypersonics and Strategic Missile Defense, Missile and Integrated Defense Systems, and Space and Launch, and counts primes like Northrop Grumman and Lockheed Martin among its customers. The company says it runs more than 100 active programs with no single program above roughly 10% of sales, which spreads its revenue across many contracts.

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

• AVAV drivers: Loitering munitions demand; Small unmanned systems franchise.
• KRMN drivers: Defense budget and missile-defense tailwind; Record backlog and demand visibility.

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: AeroVironment depends heavily on US defense procurement, so budget cycles, appropriations timing, and program decisions cause lumpy, hard-to-predict revenue and order flow. For KRMN, the most immediate risk is valuation: with a trailing P/E reported above 200 and slim GAAP earnings, the stock prices in years of strong growth, so any disappointment can drive a sharp de-rating (the shares have already swung widely, trading between roughly $43 and $118 over the past year).

Pick AVAV if you believe its drivers more; KRMN 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 AVAV and KRMN guides.

AVAV. AeroVironment trades on a growth multiple that reflects its leadership in fast-growing drone and loitering-munition categories rather than current earnings. The valuation embeds expectations of sustained defense procurement growth and successful expansion into autonomy and space. It is more volatile and richly valued than traditional defense primes, sensitive to order timing and conflict-driven demand swings.

KRMN. Figures are approximate and tied to the asOf date; verify live numbers before acting. KRMN's very high P/E reflects strong revenue growth and rising adjusted EBITDA against still-modest GAAP net income, so the multiple is best read as a gauge of how much future growth is already priced in rather than a normal earnings valuation. The 52-week range (roughly $43 to $118) shows how sensitive the shares are to sentiment on defense spending and growth.

Headline figures (approximate, early 2026): AVAV shows revenue (ttm) ~$800 million-$1 billion, operating margin ~low-double-digit percent, net income (ttm) Modest; growth reinvested, p/e (ttm) Elevated (growth multiple); KRMN shows revenue (q1 2026 quarterly) ~$151.2 million, up 51% year over year, full-year 2026 revenue guidance ~$720 to $735 million, adjusted ebitda (q1 2026) ~$44.8 million, up ~48% year over year, backlog ~$1.03 billion (up ~61% year over year).

AVAV and KRMN 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.
