Tariffs on imported polysilicon and new incentives for onshoring have suddenly put a spotlight on where solar and semiconductor supply chains are built. For investors, this mix of higher import costs and potential tariff relief could reshape which U.S. stocks quietly sit in the tailwind or headwind of policy. This article walks through 3 stocks that appear positively exposed to the latest Section 232 moves and explains why they may warrant closer attention now.

The stocks covered below are just a starting sample, and the full screen surfaced 18 more U.S. polysilicon and solar manufacturing companies with equally compelling narratives that are not discussed here. To identify and analyze the highest conviction ideas that fit this theme, head straight to the U.S. Domestic Polysilicon and Solar Manufacturing screener.

Microvast Holdings (MVST)

Microvast Holdings designs and manufactures lithium ion battery components and systems for electric commercial vehicles and energy storage, supplying chemistries ranging from lithium titanate to lithium iron phosphate alongside its own cathodes, anodes, electrolytes, and separators. The company currently generates about $372 million in revenue entirely from batteries and battery systems, and its global footprint spans transportation fleets and industrial customers across the U.S., Europe, and Asia. Microvast has a market cap of roughly $261 million, which places it firmly in small cap territory.

Microvast Holdings sits at the intersection of battery technology and onshoring policy, which is closely aligned with where the new Section 232 tariffs and incentives are directing capital. As a U.S. manufacturer supplying critical battery systems for electric fleets and renewable projects, it may be positioned to benefit from tariff relief and domestic supply chain investment. Its multi region footprint and capacity expansion plans also create a potential path to scale. At the same time, the recent securities lawsuit, reliance on higher risk borrowing and accounting changes in 2026 highlight execution and governance questions. For investors willing to conduct further research, the combination of high growth expectations, a small market cap and policy tailwinds makes Microvast a complex story to examine more closely.

Clearfield (CLFD)

Clearfield supplies the fiber management hardware that sits behind broadband, data center, and wireless networks, from cabinets and panels to outdoor enclosures and pre connectorized fiber paths. The business generates about $154 million in revenue from its Clearfield portfolio of fiber connectivity products and related solutions, and it has a market cap of roughly $374 million, which places the stock in small cap territory.

Investors watching the new Section 232 tariffs may find Clearfield interesting because it sells U.S. based fiber connectivity systems into broadband, data center, and renewable projects that could see more onshore build out. The company is already seeing steady sales and net income in 2026, is buying back shares, and is guiding to full year revenue of $151 million to $155 million despite recent margin pressure and a high P/E ratio. The key question for investors is whether growing demand for fiber, government backed broadband spending, and Clearfield’s expanding product set can offset funding delays, supply chain costs, and earnings volatility sufficiently to make today’s valuation look reasonable.

Clearfield’s steady revenue, active buybacks and high P/E suggest something in the story is not fully priced in yet. See how the full 2 key rewards and 4 important warning signs (1 is major!) might change how you view the next phase.

LightPath Technologies (LPTH)

LightPath Technologies designs and manufactures optical components and infrared camera systems that are used in defense, security, medical, industrial, and telecom applications. The company generates about $63 million in revenue entirely from its optics segment and sells into the United States, Europe, China, and other regions. LightPath Technologies has a market cap of roughly $797 million, which puts it at the larger end of the small cap spectrum.

Investors looking at U.S. onshoring themes may find LightPath Technologies interesting because it sits where precision optics, defense demand, and domestic manufacturing incentives meet. The G5 Infrared acquisition is pushing the business up the value chain into higher priced systems and long range cameras, supported by fresh capital raises and new defense orders such as the $11 million counter UAS contract in July 2026. At the same time, the company is still reporting losses, relies on higher risk borrowing, and has diluted shareholders through recent equity offerings. The mix of growth forecasts, rich pricing, and execution risk suggests there is more to this story than the headline revenue line.

LightPath Technologies is expanding into higher value infrared systems as defense and security orders increase, yet the real story only becomes clear when you consider the 2 key rewards and 2 important warning signs (2 are major!)
