We closed out our series last week with Inputs, Orbits, and Engines after having worked through the defense map domain by domain: the overarching thesis, the platforms, the counter-drone layer, the munitions restock, the sensor and electronic-warfare names, and the commercial supply chain feeding next-gen tech and major end items.
Most companies belong somewhere on that map. The handful that don’t are collected here, in a “special grab bag edition” of State of Small-Cap Defense Investing 2026.
Names in the grab bag often range across several domains at once, or in the seam between defense and “something else” in the dual-use economy, or carry a defense thesis bolted onto an unrelated one.
They run odder and higher-variance than the picks that fit a single theme, but also offer a unique angle that may otherwise go overlooked when building a well-rounded small-cap defense stock basket.
Top Small-Cap Defense Stock: Sypris Solutions $SYPR ( ▼ 2.52% )
Sypris is the name that justifies the grab bag, because it lies in four of our core small-cap defense investing categories at once with strength across each.
On the surface, there isn’t much to love. Full-year 2025 revenue fell to $119.9 million from $140.2 million, the net loss widened to $6.3 million, and the first quarter of 2026 got worse, with a $4.1 million loss and a Sypris Electronics segment that swung to an outright gross loss.
At roughly $53M this is a true micro-cap, and it screens like one. The reason to keep reading is the order book underneath the income statement, because Sypris is a contract manufacturer. For contract manufacturers, orders lead revenue by roughly twelve to twenty-four months. Right now the orders are inflecting across nearly every line while the financials work off the old downturn.
Here is the company segment by segment:
Defense
The defense leg is Sypris Electronics, which builds power-supply modules, electronic-warfare modules, and circuit-card assemblies that go inside missiles and defense systems as a subcontractor to the primes. In September 2025 it won a follow-on to manufacture and test power-supply modules for the avionics suite of a classified missile program, with production beginning in 2026.
In the first quarter of 2026, electronics orders rose 28% year over year and 269% sequentially, driven by several missile programs, a major defense-aviation program, and subsea work.
Management tied the demand to inventory replenishment and technology upgrades stemming from conflict in the Middle East, the same restocking dynamic running underneath the munitions names earlier in this series.
Space
The space leg makes circuit-card assemblies for NASA’s Orion spacecraft. In January 2026 Sypris Electronics won an expanded follow-on to produce and test space-grade assemblies supporting Orion’s sensor systems, including navigation, environmental monitoring, and crew safety, with program backlog now running through 2027.
Note that federal budget proposals have floated winding the Orion program down in the coming years, so Sypris’ space segment carries political risk the commercial work does not. Working in Sypris’s favor, of course, is the fact that space-grade flight qualification is hard to earn, and it is the moat that’ll be tough for a company of its size to come close to.
Subsea
The subsea leg could be the next big mover in Sypris’ portfolio, considering it’s right at the intersection of increased global data connectivity and artificial intelligence demand.
Sypris supplies high-reliability electronic assemblies to a leading global subsea fiber-optic cable systems provider, the kind of intercontinental cable whose buildout is being pulled along by surging global data demand. In other words, Sypris’ subsea segment is basically a data-center tailwind hiding inside a business most screens file under boring industrial.
Energy
The energy leg, inside Sypris Technologies, forges large high-pressure closures for LNG export terminals and natural-gas pipelines. Energy product orders rose 31% year over year and 38% sequentially in the first quarter.
Management has pointed to electricity demand from AI data centers as the forward driver, on the logic that more gas-fired generation means more pipeline infrastructure and more of the closures Sypris makes, making this the second AI-driven tailwind supporting the Sypris thesis. This is higher-margin work than the rest of the segment, so it lifts the mix as it grows.
Commercial Trucking & Automotive
The drivetrain leg is Sypris’ anchor in both senses, and it explains the headline numbers. The legacy core makes axle shafts and transmission components for heavy trucks under a sole-source relationship now past 25 years, and it got hit by the commercial-vehicle downturn, tariffs, and customers drawing down inventory.
As noted above, revenue fell about 31% in 2025, and that drop buried the growth sitting above it.
But two things cut the other way:
Management says the downturn is nearing an end and expects restocking to accelerate through 2026
In January 2026 the company won a new long-term, sole-source award to supply components for a global truck maker’s next-generation automated manual transmission, framed explicitly as U.S. reshoring with deliveries starting in 2027.
In other words, even Sypris’ laggard segment is rebuilding backlog.
A Unique Angle on Small-Cap Defense Investing
As you can likely tell, the setup is unusual for a company this size.
Four of the five lines ride unrelated secular tailwinds: missile replenishment, space, the data-center buildout pulling subsea and power demand, and energy infrastructure. Meanwhile, the fifth is cyclically bottoming with fresh backlog forming behind it.
That strength doesn’t show up in the income statement yet, for two reasons:
Timing. The truck collapse hit just as the growth programs entered low-rate initial production, the early phase that front-loads engineering changes, scrap, and unabsorbed overhead, so new defense and space work loses money before it makes money.
Conversion lag. Most of this backlog ships in 2026 and 2027, which means owning the stock today means owning the order book before it becomes revenue.
What’s the Risk?
Most of the typical microcap risks apply:
Cash sits at $4.8 million, thin enough that the balance sheet has little margin for error
Stockholders’ equity has been sliding toward Nasdaq’s continued-listing floor, leaving its continued exchange-traded status somewhat uncertain
It’s illiquid and swings hard on sentiment, as with most microcaps
Customer and program concentration is significant
Classified work programs mean limited outside visibility into what is actually being built, and the potential/longevity of those programs
The single number that settles the debate is Sypris Electronics gross margin, which turned negative on the ramp. If it climbs back toward positive over the next two or three quarters, the orders-convert-to-profit story is validating in real time. If it stays red, the surging backlog is just funding start-up losses against a tight balance sheet.
Ultimately, Sypris is a high-risk, high-reward microcap that demands the conviction to ride the inevitable volatility and play the waiting game, but its improving secular strength and existing thematic upside earn it the lead in this grab bag edition. The rest carry strengths of their own, and each runs shorter by design, single-thesis names that don't need a full workup apiece.
Microdisplays & Human-Machine Teaming: Kopin $KOPN ( ▼ 4.82% )
Kopin makes the microdisplays inside thermal weapon sights, helmet-mounted systems, and first-person-view drone goggles, the soldier-vision layer. In May it won a $21.5 million follow-on production contract for U.S.-made thermal-imaging eyepiece assemblies for a major defense prime.
Likewise, Kopin is standing up full-scale domestic OLED microdisplay manufacturing at its Massachusetts headquarters because demand for USA-built displays for FPV systems and weapon sights is rising. This folds the dual-use and supply-chain-integrity threads into one name, earning Kopin a spot as a prime grab-bag stock.
At roughly $680M Kopin is comfortably outside of microcap range, and it ran hard to get there, more than doubling over the past year with the volatility to match. A recent MicroLED collaboration aimed at AI data centers adds an unrelated lottery ticket on top.
Personnel Protection: Cadre Holdings $CDRE ( ▲ 4.43% )
Cadre Holdings is a soldier-protection consolidator, making body armor, duty gear, and explosive-ordnance-disposal equipment for military and law-enforcement customers.
The company is profitable, pays a $0.40 annualized dividend that yields roughly 1.4%, and in early 2026 completed its acquisition of TYR Tactical, adding plate carriers and hard armor, with full-year 2026 sales guided to $736 to $758 million.
At roughly $1.2B, Cadre is a larger name in the grab-bag, but it is also one of the few here that reads as a cash-generative roll-up rather than a speculation. The near-term cost is margin: first-quarter profit compressed as the company absorbed acquisition and integration expense.
Dual-Use Training Systems: VirTra $VTSI ( ▼ 1.54% )
VirTra builds judgmental use-of-force, firearms, and de-escalation training simulators for law enforcement and the military, with recurring revenue through its STEP subscription program and a new drone-defense training system that ties it loosely to the counter-UAS theme.
The most recent quarter was weak, revenue down 51% to $3.5 million and a swing to a loss, which management pinned on customers being unable to take delivery in the quarter rather than on demand.
That is the perennial risk in a lumpy, government-funding-dependent micro-cap (market cap around $36M). The thesis is training modernization and a growing recurring-revenue mix, but the open question is whether the soft quarter was a timing trough or a demand signal.
Small-Cap Optics Stock: Optex Systems $OPXS ( ▼ 0.83% )
Optex Systems (OPXS) is a micro-cap that makes the optics soldiers actually look through on armored vehicles, the periscopes, vision blocks, and thermal sights on the Abrams, Bradley, and Stryker, plus specialty optical coatings and howitzer sighting components.
First-half fiscal 2026 revenue was essentially flat as the government shutdown and a delayed appropriations bill pushed contract awards into the back half of the year, with full-year revenue guided to $43 to $45 million and gross margin improving as legacy loss-making contracts roll off.
At around $87M, OPXS is tiny and tied to vehicle-program funding cycles, but it is a real, niche supplier with a backlog rather than a concept.
The “Balanced Basket” Option: SPDR S&P Aerospace & Defense ETF $XAR ( ▼ 1.06% )
Every name above is a single-point bet, and several carry the dilution and going-concern risk that comes with the territory. The one-ticker route to the small-cap end of defense is XAR, and the reason it suits this theme is its modified equal-weight construction, which spreads roughly 40 holdings across large-, mid-, and small-cap names at close to the same weight rather than cap-weighting them.
That does three things at once:
The growth names (Rocket Lab, Kratos, AeroVironment, on down to National Presto at the bottom of the book) carry enough weight to register in returns instead of washing out against Lockheed.
The large-cap slice rides underneath as ballast, supplying the funded backlogs, government-anchored revenue, and balance-sheet depth the smaller-caps can’t.
Any single blowup, a discounted raise or a lost recompete, is a two-to-three-percent position rather than a portfolio event, which counts for something in a cohort where idiosyncratic risk runs high.
At 0.35% it is also on the cheaper side of the major defense funds.
The tradeoff is that same mechanism in reverse:
The small-cap tilt that supplies the upside also lifts the beta.
XAR has historically drawn down harder than its cap-weighted peers when the sector turns.
Equal weight buys growth participation at the cost of drawdown tolerance: when defense rolls over, this rolls over further.
Ultimately, XAR serves as a middle path between the prime-dominated funds, where the small-caps are rounding errors, and the single names above, where there is no ballast at all.
‘Til Next Time
What these names share is that they don’t share much, which is the reason to look at them together. Some are cheap because the market has them right and there’s inherent risk to the company, whether systemic or execution-based. Some are cheap because a real business is buried under a bad quarter, a funding-cycle air pocket, or an income statement that hasn’t caught up to the order book. Telling those apart is a name-by-name job, not a theme, which is exactly why they’re included as a grab bag instead of a section.
