Trade policy is back in the spotlight as new US tariffs, legal challenges from 25 states, and pushback from Mexico’s President Claudia Sheinbaum put cross border commerce under fresh pressure. That kind of uncertainty can punish some companies while opening doors for others that rely more on US based manufacturing. This article walks through three US Domestic Manufacturing stocks exposed to this news and explains how these shifts could matter for your portfolio.

The three US domestic manufacturing stocks covered below are just a starting sample, and the full screen surfaced 21 more companies with equally compelling stories that fit this theme but are not covered in the article. To go wider and deeper, identify and analyze your own highest conviction ideas directly in the US Domestic Manufacturing Stocks screener.

Nextpower (NXT)

Nextpower is a Fremont based solar and energy technology company that supplies tracking systems, software and foundations for utility scale solar projects to engineering firms, project developers and asset owners. It currently generates about US$3.6b of revenue from electronic components and parts, and the business is valued by the market at roughly US$14.9b.

Investors watching trade policy should pay attention to Nextpower. Management reports that tariffs are already running through the P&L. At the same time, a heavily localized supply chain, 100% domestic content tracker options and more than 25 US partner plants give customers a way to limit cross border exposure under the new tariff regime. In addition, a multi billion dollar backlog, recent acquisitions in storage and power conversion and high reported earnings quality contribute to the view that the business is central to US solar buildout. The catch is concentration in the US and policy risk, which can quickly feed through to pricing and margins.

Nextpower’s US centered supply chain and multi billion dollar backlog hint at a story that many investors may be only half seeing. Use the 4 key rewards and 1 important warning sign to see how policy risk and reported strengths really line up.

Primoris Services (PRIM)

Primoris Services is a Dallas based contractor that builds and maintains critical infrastructure across utilities, energy, renewables and transportation in the US and Canada. It works on gas and electric networks, grid connections for renewables, energy storage and large industrial projects. The stock is valued at about US$4.9b.

Primoris Services sits at the intersection of US domestic manufacturing and infrastructure buildout, which makes it directly relevant as tariffs push more projects and supply chains onshore. Management has told investors that most materials are either supplied by customers or sourced from mostly domestic suppliers, and that many contracts allow tariff related cost pass through, which can help protect margins. At the same time, you are getting exposure to long term themes like renewables, power delivery and data centers. However, the backlog has held up even as Q2 2026 revenue and guidance reset remind you that execution risk and earnings volatility are still part of the story.

Primoris Services sits at the crossroads of reshoring, renewables and data center buildout, yet many investors may only be seeing the headline volatility. Get the full picture in the 3 key rewards and 3 important warning signs (1 is major!)

Koppers Holdings (KOP)

Koppers Holdings is a Pittsburgh based chemicals and materials company that treats wood for railroads and utilities, supplies preservatives for residential and agricultural lumber, and produces carbon compounds used in aluminum, steel, rubber and construction. It generates about US$911.8 million of revenue from Railroad and Utility Products and Services, US$596.6 million from Performance Chemicals and US$492.9 million from Carbon Materials and Chemicals, with intersegment eliminations of US$123.2 million. The stock is valued at roughly US$1.0b.

Investors looking at US domestic manufacturing stocks may find Koppers Holdings interesting because it sits at the intersection of rail infrastructure, grid hardening and treated wood demand, while running a largely US centered production base that can benefit when broad tariffs make imports less competitive. The company is working through tariff related cost noise and portfolio reshaping, such as the planned Stickney shutdown and a high debt load. It is also buying back shares, paying a dividend and aiming to lift margins and free cash flow as its “Catalyst” efficiency program and capacity consolidation take hold. The mix of tariff exposure, potential benefit from domestic demand and ongoing restructuring means the headline story is only part of what is really driving Koppers today.

Koppers Holdings appears to be a straightforward tariff and infrastructure story, yet its mix of debt, buybacks and “Catalyst” efficiency plans suggests a more complex situation developing beneath the surface.
