Made in America: 7 Small-Cap Stocks Reindustrializing the U.S.

The reindustrialization trade is not a forecast anymore, and it may end up being the next big wave closing out the 2020s as traders make the move from "bits to atoms," looking to deploy capital in the real world to support growing demand for infrastructure (AI, energy, and otherwise), manufacturing, and supply chain sovereignty.

Capgemini's 2026 survey of manufacturers on both sides of the Atlantic found roughly three-quarters now running a reindustrialization strategy, with the money flowing hardest toward semiconductors and defense.

Y Combinator has an entire Request for Startups aimed at "techno-industrialists," and the founders are answering: Nox Metals, a Detroit outfit out of YC's 2025 batch, raised an $11.5 million seed in June to reopen a WWII-era factory and sell metal at what it calls software speed.

In other words, the venture class that spent a decade funding B2B SaaS and AdTech has discovered the machine shop.

Today seems a fitting time to run a small-cap screen on the reindustrialization effort, what with America's 250th birthday this weekend and on the heels of the annual Reindustrialize Summit wrapping up in Detroit last month, where more than 1,500 people from government, capital, and the factory floor spent two days on exactly this theme.

Here’s the rub for anyone trying to invest in it: the obvious names already ran.

Bottom line: by the time a reindustrialization pure-play is a household ticker, the small-cap window has closed.

To that end, this screen will go one layer down, to the domestic manufacturers still trading like small-caps: companies making chips, steel, airframes, gearboxes, and printed metal parts on American soil.

Most are under $1B. Some are compounding in the background, and some are turnarounds mid-pivot.

But all of them build here.

If reindustrialization has a purest expression, it is a chip fab on American soil, and SkyWater runs the largest exclusively U.S.-based pure-play semiconductor foundry there is. Its fabs in Minnesota, Texas, and Florida turn out analog, mixed-signal, MEMS, and specialty parts under a model the company calls Technology as a Service, and it holds a DMEA Category 1A Trusted Foundry accreditation that makes it a default supplier to defense programs that cannot send designs offshore. Fiscal 2025 revenue reached $442.1 million, up 29%, with the acquired Fab 25 in Austin adding volume and the company swinging to a $118.9 million net profit.

The complication that may actually enhance the industrialization angle is that SkyWater is being acquired.

Shareholders approved a merger with IonQ in May, and the deal is expected to close in the second or third quarter of 2026. That changes what owning SKYT means. This is no longer a bet on an independent foundry compounding on its own, but on a U.S. quantum-computing company absorbing the secure domestic manufacturing base it needs to build hardware at scale.

It comes at an opportune time, too, as the government increasingly signals intent to go all-in on quantum in the coming years, with capital flows matching the sentiment.

Mayville Engineering does not make a product you have heard of. It makes everybody else's.

Founded in 1945 in Wisconsin, MEC is a vertically integrated contract manufacturer, doing stamping, laser cutting, forming, welding, coating, and assembly for original-equipment customers in commercial vehicles, construction, agriculture, and the part of the economy actually growing right now.

Data center and critical power is the reason to look closely at MEC as a prime reindustrialization trade. In Q1 2026, that end market grew 71% year-over-year, and the company booked $50 million of new datacenter and critical-power awards while its legacy vehicle and ag markets stayed soft.

That mix shift is the whole thesis: a contract manufacturer is a leveraged bet on which industries are expanding, and MEC is redirecting a shop floor built for tractors and truck frames toward the enclosures, bus bars, and power infrastructure that AI buildout consumes. Net sales rose to $144.8 million in the quarter even with the old business flat.

The caveat sits on the balance sheet. MEC carries meaningful debt, with net leverage above four times EBITDA after its July 2025 Accu-Fab acquisition, and it ran a net loss in the quarter as new-program launch costs landed before the revenue fully ramped. Management has guided toward deleveraging in the back half of 2026 as those programs reach full production.

At a market cap near $860M, this is a small-cap industrial priced for the transition to work, not one being handed the benefit of the doubt. The demand is visible in the order book, thought he risk is whether the balance sheet carries the company to the other side of the ramp.

Every reshored factory, data center, and rebuilt bridge needs concrete, and reinforced concrete needs steel wire. Insteel is the largest U.S. manufacturer of steel wire reinforcing products, running eleven plants across the country that make prestressed concrete strand and welded wire reinforcement for nonresidential and infrastructure construction.

It is about as literal a made-in-America holding as this screen contains: domestic plants, domestic demand, and a product too heavy and low in value-to-weight to import economically in the first place.

Tariffs on downstream steel products fall on exactly the imported reinforcement that competes with Insteel, and the company runs debt-free with more than $50 million in cash and an undrawn revolver, which gives it room to buy up capacity when smaller competitors struggle. That balance sheet is the quiet advantage in a cyclical business.

Conviction comes with a caveat that showed up in the numbers. Insteel's Q2 2026 report missed expectations, a reminder that reinforcement demand tracks construction cycles and does not rise in a straight line just because the macro story is favorable.

This is an infrastructure-and-onshoring materials play at roughly $600 million, valued on volume and pricing spreads, but keep an eye on how macro shifts may impact downstream constructors like Insteel.

Reindustrialization is not only smokestacks. Part of it is making domestic manufacturing fast enough to beat an overseas quote that takes a week.

Proto Labs is the closest thing small-cap has to that idea in one ticker: a digital manufacturer that runs CNC machining, injection molding, sheet metal, and 3D printing out of its own factories, with a software front end that turns an uploaded part file into an instant price and a design-for-manufacturability analysis.

In February it also launched ProDesk, an AI-driven quoting and DFM platform, and it has been expanding domestic metal 3D printing with a dedicated DMLS facility in Raleigh.

The differentiator is that Proto Labs actually owns the machines. Marketplace competitors broker other people's capacity but Proto Labs is the shop, which is why its aerospace and defense work carries ITAR registration and AS9100 certification rather than a promise to find a supplier who has them. That is the reshoring pitch made concrete: secure, certified, quick-turn parts produced without a purchase order crossing an ocean.

Two qualifiers:

What it offers in exchange is the cleanest financials of the group: it is profitable, it grew to a record first quarter in 2026, and it generates cash. Among reindustrialization names, it is the one you do not have to underwrite a turnaround to own.

Velo3D prints metal parts that are difficult or impossible to machine conventionally, and it prints them for customers who care about performance far more than price: rocket engines, jet components, defense hardware.

Its Sapphire printers are assembled in the United States, and the company has spent the past year converting a near-death 3D-printing story into a defense-supply story. The contract list is the evidence. Velo3D holds a $32.6 million Department of War award for Project FORGE, a $9.8 million five-year IDIQ with the Defense Logistics Agency, an $11.5 million production contract with a U.S. defense prime, and a qualification and research agreement with the Army's ground vehicle center. SpaceX is a customer.

The turnaround is visibly underway. Q1 2026 revenue rose 48% year-over-year to $13.8 million, gross margin flipped positive after running deeply negative the prior quarter, and the company cut its debt sharply while targeting positive EBITDA in the second half of the year.

To be fair, Velo3D is the most speculative name in this screen. It has funded the turnaround by repeatedly selling stock, including a $50 million raise in April and a $100 million at-the-market shelf, so existing holders are being diluted as the business scales.

And the stock trades like it: shares ran roughly 64% in a quarter, and a 2X leveraged single-stock ETF now exists to bet on daily moves, which is not the signature of a calm shareholder base.

At a market cap in the several-hundred-million range, Velo3D is a domestic additive-manufacturing business with a booked defense pipeline wrapped in a momentum vehicle (and borderline meme stock), and the tape reflects both halves of that description.

Seven years of booked work is a strange thing to find attached to a $70M market cap, but that is CPI Aerostructures. The company builds the physical structure of military aircraft, wing components, engine inlets, and pod systems, out of a single plant in Edgewood, New York, operating as both a prime contractor to the Department of War and a Tier 1 subcontractor to the aerospace majors. That is a useful position to hold when the entire national conversation is about rebuilding the defense industrial base.

The order book carries the argument. Recent awards include F-16 structural assemblies from Lockheed Martin running through 2028, missile wing assemblies from Raytheon, and engine inlets from Embraer, and the company closed Q1 2026 with a total backlog of $495 million against quarterly revenue of $17.4 million, more than seven years of work at the current run rate. The quarter itself swung to a $1.2 million profit from a loss a year earlier as a richer product mix lifted gross margin above 25%.

Size is the obvious caveat, and it cuts deeper than a line about volatility. A micro-cap with a history that includes a listing-compliance stumble earlier this decade does not get the balance-sheet forgiveness a larger contractor would, and a single program delay moves CPI's numbers in a way it never would at a Lockheed.

But that cuts the other way too: a single new award moves them just as hard, and a company with seven years of booked defense work and a freshly positive income statement is a different animal than the turnaround target CPI was a few years ago.

Broadwind spent years known as a wind-tower manufacturer, which in 2026 is a difficult place to be. So it left.

In April it sold its wind-focused heavy-fabrication facility to a subsidiary of IES Holdings and repositioned as a diversified precision manufacturer aimed at power generation, defense, and critical infrastructure, withdrawing its full-year guidance while the transition settles. This is a company mid-pivot, which is exactly why it still trades at a market cap around $105M million.

What is left after the divestiture is the more interesting business. Broadwind's gearing segment makes gearboxes and precision-machined components out of U.S. plants for power generation, mining, and defense customers, and demand there is running with the grid. In the Q1 2026 gearing orders rose more than 65%, driven by gas-turbine content tied to the same AI-data-center power buildout showing up across this screen, with management pointing to early defense demand on top of it. Selling the policy-dependent wind business to lean into power and defense is a coherent response to where the industrial money is actually going.

The risk is that transitions are messy and this one is early. Broadwind pulled guidance, its heavy-fabrication revenue dropped sharply as it exited product lines, and it burned cash over the trailing year even while reporting a small net profit, so the reported earnings and the cash statement disagree in a way worth watching.

This is the emergent reindustrialization theme in its rawest small-cap form as a domestic manufacturer actively rebuilding itself around the demand that is growing and away from the demand that is not, priced at a level that reflects how unfinished that work still is.
