Nucor: The US Walled Garden Compounder

I will soon release the most comprehensive deep dive into Nucor ($NUE), as voted on by my subscribers in The Heavy Metal Meltdown (steel/aluminum primer post Middle East crisis), a company sitting at the intersection of the most durable trade wall in American industrial history and the most significant free cash flow inflection in the North American steel sector.

Most investors see a cyclical steel trade that has already doubled and call it a squeeze. What they're missing is that the 50% Section 232 tariffs are not a negotiating tactic, they've been codified, expanded to cover 600 derivative products, and hardened by a post-Middle East political environment that treats domestic steel capacity as a national security asset. Import share of the US finished steel market has collapsed from 22% to 14%. That volume doesn't come back. And Nucor, as the largest producer with the broadest product portfolio, captures a disproportionate share of every point of recaptured demand.

Layered underneath the Walled Garden is something the market is significantly underpricing: the completion of a $20bn capital programme that depressed free cash flow for six consecutive years. FCF inflects from negative $188m in 2025 to over $4bn by 2028. The capex burden is gone. The harvest is just beginning.

Nucor is a compounding machine, having retired 20% of its share count since 2017 and just authorized the largest single buyback in company history at $4bn, roughly 8% of current market cap.

Management explicitly targets the most defensible end markets in the US economy: AI data centres, naval shipbuilding, CHIPS Act fabs, and federal infrastructure. They can now supply nearly every steel product that goes into a modern hyperscale data centre from a single integrated portfolio. That is not commodity exposure. That is solutions selling into the most structurally protected demand in the economy.

At current prices, you are paying approximately 8x forward EBITDA for a structural earnings reset with years of upside ramp ahead, a 53-year dividend aristocrat with the highest credit rating in North American steel, and a buyback machine retiring 4 to 5% of the share count annually while you wait for the market to grasp what has already been built.
