4 Defense Stocks Poised to Beat Expectations This Earnings Season

Zacks expects Aerospace sector third-quarter 2026 earnings to rise 186.2% on 13.1% higher revenues and identifies Kratos, HEICO, Curtiss-Wright and AeroVironment as poised to beat estimates, based on positive Earnings ESPs and qualifying Zacks ranks. Consensus EPS growth estimates range from 4.6% for AeroVironment to 50% for Kratos; the article also cites rising defense demand and backlogs, while warning that component shortages and labor costs could constrain production and margins. These are forecasts, not reported results.

Analysis

The sector-level earnings growth figure is a poor proxy for these stocks’ upside: a low comparison base can produce outsized growth without a comparable change in forward cash flows. A positive Earnings ESP is a screen, not evidence that a beat will translate into higher guidance or durable estimate revisions. In particular, AVAV’s unusually large ESP warrants checking the estimate dispersion and revision history before treating it as a strong signal.

The more useful distinction is execution exposure. KTOS and AVAV offer greater sensitivity to delivery ramps and program awards, so manufacturing bottlenecks can defer revenue even when funded demand is intact. Capacity expansion only creates value if qualified labor, components and customer acceptance keep pace; otherwise fixed-cost absorption and working-capital needs can disappoint. HEI’s aftermarket exposure may be a relative stabilizer if defense program schedules slip, while CW’s mix of defense, commercial aerospace and nuclear-related work gives it different demand drivers—but neither is immune to labor or input-cost pressure.

Over the next several days, the catalyst is the quality of the print, not simply an EPS beat: delivery cadence, margins, cash conversion, backlog funding and guidance matter more. Over 1–3 months, look for estimate revisions and evidence that capacity converts into shipments. Over 6–18 months, sustained procurement and modernization can support demand, but budget timing and program execution can interrupt it. The contrarian risk is that investors capitalize backlog and geopolitical demand as near-term earnings certainty; backlog is not revenue until funded, produced and accepted.

Key Decisions for Investors

• Avoid a basket long solely on the Zacks screen. Into earnings, keep exposure modest or wait for results; an EPS beat without maintained or raised delivery, margin and cash-flow guidance is not confirmation.
• Post-print, consider a relative long HEI / short KTOS or AVAV only if results show stronger HEI aftermarket execution and delivery or margin slippage at the higher-ramp names. This is a conditional execution-quality trade, not a valuation call; exit the thesis if KTOS/AVAV demonstrate accelerating shipments and improving cash conversion.
• For KTOS and AVAV, verify funded-backlog conversion, production capacity utilization, supplier availability and working-capital movement before adding. Treat a backlog increase without shipment progress or cash conversion as a warning, not a bullish catalyst.
• For CW, monitor order conversion and margins alongside defense demand; commercial aerospace and nuclear-related exposure may diversify drivers but does not eliminate execution risk. Reassess if guidance weakens or order growth fails to translate into revenue.
