Preview: The largest steel producer in America runs on scrap, and it is having a very good year. It reports earnings tonight, and its own forecast has been public for six weeks.

The largest steel producer in America is also North America's largest recycler. Nucor melts scrap into new steel, about 20 million tons a year, and sells it back to the country as beams, sheet, and bar. Easy to miss lately, with oil and the war behind it owning the headlines. But Nucor is having a very good year, and after market close today, it reports quarterly earnings. Don't expect much suspense. Six weeks ago, as it does every quarter, the company told everyone what to expect: somewhere between $4.70 and $4.80 a share, nearly double the same quarter last year. About twenty cents of that is a paper gain on a stake in Helion, a fusion-power company, rather than anything to do with steel.

The old way to make steel starts with iron ore and coal in a blast furnace. Nucor's way starts with yesterday's steel: an electric arc furnace melts scrap with an industrial bolt of lightning, hot enough to turn a shredded car back into liquid metal. Only two companies in America still make it the old way; more than 70 percent of American steel now starts as scrap. Nucor built the biggest version: its recycling arm buys the scrap, its mills sell the steel, and it is paid on both sides of the loop.

Three things explain the strong year. Washington's 50 percent steel tariff held (it survived a Supreme Court test in February), and imports are down about a quarter. American mills kept their own output disciplined. And scrap prices stayed roughly flat while the benchmark price of American sheet steel rose about 25 percent. A demand boom is not on that list: Nucor's own forecast says volumes are stable. The price is doing the lifting.

Last quarter, its steel mills shipped a record volume and total profit came in at nearly five times the year-earlier figure. If tariffs keep holding imports down and scrap stays cheap, quarters like that keep coming, because the profit lives in the gap between what scrap costs and what steel sells for.

Our scores were not early on Nucor. They warmed to it in February, then backed off by March. What changed everything was the first-quarter report on April 27: revenue up 21 percent from a year earlier, and profit of $3.23 a share against 67 cents. Our growth reading is built from comparisons like those, a measure of how fast sales and profits are rising versus the quarters and years before, and it re-scores the stock in a single trading day. The scores roughly doubled, and our action gauge of how well everything lines up jumped from the middle of its range to near the top.

The move was that sharp because of where steel had just been. The industry runs in cycles, and a year ago Nucor sat near the bottom of one: 67 cents a share in the first quarter of 2025. Now prices are up about 25 percent, scrap is flat, and every fresh quarter gets measured against that weak base. The filing charged the growth math.

Steel Dynamics runs the same loop. Founded by former Nucor executives, it melts the same scrap and even keeps the same habit of publishing its own forecasts. It reported on July 20, and the same signature showed up in miniature: fresh numbers, and a growth reading that stepped up within days.

We keep a name for companies like these two: Circular Infrastructure, our theme for businesses whose raw material is other people's waste. The steelmakers anchor it. Around them sit the recovery businesses most people know better as garbage companies: Waste Management and its landfills, Clean Harbors and its hazardous-waste plants, a young company trying to do for plastic what Nucor did for steel. The through-line is one trade: get paid to take the waste in, get paid again for what comes out. Scrap steel is that idea running at industrial scale for more than half a century.

Alongside our scores, we run a set of simulated portfolios picked entirely by our data, published in the open (we call the system the Opinionated Machinery). It buys from a ranked list of setups, and the setup score is a blend of growth, timing, and value. So when Nucor's growth reading doubled in April, the whole setup vaulted. Our three production portfolios opened in May and all three bought it; all three still hold it. The machine's longer-view ranking list, built from about two years of daily head-to-head comparisons across all 200 names, tells the same story: Nucor sits third, up 102 places in three months, and Steel Dynamics jumped 42 places this week to 13th after its own report.

Scorecard — Nucor (NUE)

The picture in one line: strong growth at a fair price, with one honest wrinkle. Its profitability score sits just below the middle of our pack; it wins on growth and value, not quality.

Nucor's stock is up 46 percent this year, about 7 percent off its high, and the forecast has been public since mid-June: little of tonight is a secret. What we’re waiting to see is what the filed details will do to our scores. The last report moved them more in one day than the prior four months combined.

Tonight after the close, the actual numbers behind June's forecast arrive. The call is Tuesday morning, the Fed decides on rates Wednesday, and the inflation and growth data land Thursday.
