5 Small-Cap Defense Stocks April 2026 — Scored for NATO Build-Up
5 small-cap aerospace & defense stocks scored on fundamentals. April 2026 data as NATO members ramp to 3.5% GDP defense spending. Monthly updates.
NATO members agreed in 2025 to ramp defense spending from 2% to 3.5% of GDP by 2035. The U.S. fiscal 2026 National Defense Authorization Act proposed $924.7 billion. Defense is one of the strongest structural tailwinds in 2026 — but small-cap defense stocks still trade with huge dispersion based on contract wins and balance sheet quality.
We scored every small-cap aerospace & defense stock in our database. Here are the top 5 by total score for April 2026.
Why Small-Cap Defense Is Different
Small-cap defense isn't like small-cap tech or biotech. Most of these companies sell to a small number of customers (DoD, NATO primes, allied militaries) on multi-year contracts with long sales cycles. That creates predictability — and concentration risk.
Key scoring angles for defense small-caps:
- Contract visibility (we approximate via revenue growth + margin stability)
- Balance sheet resilience for multi-year R&D/production cycles
- Insider alignment — especially founder-led defense companies
- Dilution discipline — defense companies that dilute heavily often lose contracts
Top 5 Small-Cap Defense Stocks by Fundamental Score — April 2026
1. EHang Holdings (EH) — Score: 86.1 | Grade: EXCELLENT
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | +288.5% | 100 |
| Gross Margin | 61.4% | 87 |
| Cash Runway | Profitable | 100 |
| Debt/Equity | 24.4 | 80 |
| P/S Ratio | 2.1x | 95 |
| Rule of 40 | 232.8 | 100 |
| Insider Ownership | 0.6% | 5 |
| 12m Dilution | -63.5% | 100 |
What drives the score: Chinese autonomous aerial vehicle (AAV / eVTOL) company with explosive revenue growth (+288% YoY), 61% gross margins, and net share buybacks (-63% "dilution" means they bought back 63% of the stock!). Rule of 40 of 232 is extraordinary.
Red flags: Very low insider ownership (0.6%). China-based, which carries political risk for defense-adjacent applications. Classified as Aerospace & Defense in our data but positioned at the eVTOL/mobility edge rather than traditional defense.
Market cap: $0.89B
2. Cadre Holdings (CDRE) — Score: 67.9 | Grade: SOLID
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | +17.6% | 28 |

| Cash Runway | Profitable | 100 |
| Debt/Equity | 76.6 | 31 |
| P/S Ratio | 2.3x | 93 |
| Rule of 40 | 30.4 | 66 |
| Insider Ownership | 28.6% | 98 |
| 12m Dilution | 0.2% | 99 |
What drives the score: Body armor, ballistic helmets, duty gear for military and law enforcement. Steady profitable grower, 29% insider ownership (founder-operator), no dilution. Classic defensive defense play.
Red flags: Heavy debt load (D/E 76). Revenue growth is modest (+17%). Won't double overnight, but also won't go to zero.
Market cap: $1.43B
3. TAT Technologies (TATT) — Score: 56.2 | Grade: SPECULATIVE
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | +33.7% | 54 |

| P/S Ratio | 4.3x | 77 |
| Rule of 40 | 41.9 | 82 |
| Insider Ownership | 7.3% | 52 |
| 12m Dilution | 15.5% | 24 |
What drives the score: Israeli aerospace MRO (maintenance, repair, overhaul) for commercial and military aircraft. Solid growth, reasonable balance sheet, exposure to NATO air fleet modernization.
Red flags: 14-month runway is tight. 15% dilution in 12 months. Aviation MRO is margin-thin (22% gross).
Market cap: $0.74B
4. Red Cat Holdings (RCAT) — Score: 51.9 | Grade: SPECULATIVE
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | +286.0% | 100 |
| Gross Margin | 20.6% | 28 |
| Cash Runway | 4.1 months | 7 |

| Rule of 40 | 180.1 | 100 |

| 12m Dilution | 53.0% | 0 |
What drives the score: Drone company that won the U.S. Army Short Range Reconnaissance (SRR) Program of Record in Nov 2024 with Black Widow. +286% revenue growth reflects the contract ramp.
Red flags: 4-month cash runway — needs financing. P/S 258 — unprofitable with valuation baked on future contracts. 53% dilution in 12 months. High growth, high risk.
Market cap: $1.92B
5. Smith & Wesson Brands (SWBI) — Score: 50.8 | Grade: SPECULATIVE
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | -11.4% | 0 |
| Gross Margin | 26.8% | 36 |

| Rule of 40 | -6.9 | 15 |
| Insider Ownership | 2.1% | 17 |
| 12m Dilution | -41.2% | 100 |
What drives the score: Legacy firearms manufacturer. Cheap (P/S 1.3x), long runway (42 months), aggressive share buybacks. Defense adjacency is debatable but it's classified in the sector.
Red flags: Revenue DOWN 11% YoY. Consumer firearm cycle is soft. This is deep-value, not growth-defense.
Market cap: $0.62B

What This List Tells You About Small-Cap Defense Right Now
1. Drone pure-plays are the growth story. Red Cat (+286% revenue) shows what happens when you win a DoD Program of Record. But the balance sheets aren't there yet — RCAT has 4 months of cash.
2. Profitable defensive names exist. Cadre (CDRE) is the boring-but-solid pick — steady profit, founder-led, no dilution. Less upside, less downside.
3. Classification matters. EHang scored 86 but is really an eVTOL/urban-mobility name, not traditional defense. Smith & Wesson is classified in the sector but is consumer firearms. Know what you're buying.
Risks Worth Knowing
Defense contracts are multi-year — delays and cancellations are common. A contract loss can be catastrophic for a small-cap that derived 40%+ of revenue from one program. The NATO 3.5% GDP commitment is aspirational, not binding. Actual spending growth depends on national budgets, which change with elections.
Export controls on dual-use technology (drones, AI, quantum) can shift overnight and affect specific names.
