3 US Manufacturing Stocks Riding The Battery Materials Onshoring Shift
Supply chains for batteries and clean-tech materials are quietly being rewired, and the Pentagon’s conditional $250m loan to 6K to build a Tennessee plant puts that shift in sharp focus. Government money flowing into U.S. production can reshape which stocks benefit from onshoring and which ones get left behind. This article unpacks that story and walks through 3 stocks exposed to this news so you can judge the risk and potential.
The three stocks covered below are just a sample of the opportunities linked to U.S. onshoring of battery materials and clean-tech manufacturing, and the full screen surfaced 22 more companies with equally detailed stories that do not fit into this article. To identify and analyze the highest conviction ideas for your own watchlist, head straight into the U.S. Onshoring of Battery Materials and Clean-Tech Manufacturing screener.
Enphase Energy (ENPH)
Overview: Enphase Energy designs and sells solar based home energy systems built around microinverters, batteries, software, and related services worldwide.
Operations: Enphase Energy generates about $1.2b from solar photovoltaic solutions, with roughly $998 million from the U.S. and $213 million from overseas markets.
Market Cap: $3.8b
Enphase Energy matters for this onshoring theme because its U.S. built microinverters and batteries tie clean electricity, storage, and grid hardware directly to domestic manufacturing.
“High U.S. manufacturing exposure and FEOC compliant supply chains position Enphase Energy to qualify for domestic content benefits. At the same time, reciprocal tariffs already reduced Q1 2026 gross margin by 4.3 percentage points and Q2 2026 gross margin by 2 percentage points. Any further trade or tariff actions could offset cost roadmaps and keep long run net margins below what current product plans imply.”
What really moves the needle from here is how one quiet cost pressure shapes the balance between future demand and profitability.

Century Aluminum (CENX)
Overview: Century Aluminum produces primary aluminum and alumina for industrial customers, tying its U.S. smelters directly into EV, battery enclosure, and clean-tech supply chains.
Operations: Century Aluminum generates about $2.7b in primary aluminum revenue, with roughly $2.1b from the U.S. and $545 million from Iceland.
Market Cap: $3.0b
Century Aluminum gives you direct exposure to the metal that frames EV bodies, battery housings, and a lot of clean-tech hardware. The policy focus on secure Western supply has pushed the company toward bigger, more integrated projects that could reshape how it earns its money.
“The July 20, 2026 executive order that allows the planned Oklahoma joint venture to import up to 300,000 tonnes per year of primary aluminum at a 25% tariff rather than 50% gives Century Aluminum scope to use that lower duty capacity to refine its product mix toward higher value volumes, which would directly affect future revenue and net margins as the project ramps.”
What really decides how much value Century Aluminum extracts from this theme is how one unresolved cost and pricing equation ultimately settles.
That pricing equation is only the start, and the full full narrative for Century Aluminum shows how Century Aluminum’s tariff window, power costs, and project timing could be quietly accelerating or stalling value.
SolarEdge Technologies (SEDG)
Overview: SolarEdge Technologies sells solar inverters, power optimizers, batteries, EV chargers, and software that manage electricity for homes and businesses worldwide.
Market Cap: US$1.9b
SolarEdge Technologies gives you direct exposure to U.S. made solar hardware and storage equipment that link clean power to onshore manufacturing and grid upgrades, which is why it sits in the center of this onshoring themed screen.
“Exporting U.S. manufactured inverters and optimizers at scale from Utah, Texas and Florida into global markets, while still capturing 45X benefits and complying with FEOC and FCC Covered List rules, could create a cost base that is structurally lower than offshore competitors and sustain a higher gross margin profile than analysts currently model.”
The real swing factor is how one quiet shift in product mix and factory utilization filters through into long run profitability and cash generation.
That quiet shift in profitability is exactly what the full narrative for SolarEdge Technologies unpacks, showing where SolarEdge Technologies might be accelerating or where current expectations could be masking upside.
