The first consequential report of the summer’s busiest earnings week didn’t come from a chipmaker. Steel Dynamics released second-quarter results after Monday’s close: net sales of $6.1 billion, net income of $534 million, and diluted EPS of $3.69 — up 84% from $2.01 a year ago and above the company’s own June guidance of $3.51–$3.55, even after absorbing a $16 million write-down for relocating a planned aluminum slab center out of Arizona. Steel shipments hit a record 3.7 million tons. Adjusted EBITDA of $921 million was up roughly 73% year over year, and operating income of $700 million rose 30% from the first quarter alone.
The “why” matters more than the beat. CEO Mark Millett’s explanation reads like a policy document: pricing improved, customer inventories remain “lower than historical norms,” and backlogs and lead times keep extending — conditions he credited to “domestic trade actions, manufacturing reshoring, infrastructure program funding, and the increasing regionalization of supply chains within the United States.” Translation: tariff walls plus physical buildout equals pricing power. The clearest evidence sits in fabrication, where the order backlog is nearly 45% higher than a year ago and now stretches into the first quarter of 2027, on demand from commercial construction, data centers, manufacturing, warehousing, and healthcare. Long-product demand is, in Millett’s words, “extremely strong” — structural steel and railroad rail in particular.
The one soft spot is self-inflicted and shrinking. Aluminum startup losses ran $33 million — a 48% sequential improvement — as the new Mississippi flat-rolled mill commissions its third and final cold mill toward full 650,000-metric-ton capacity, with management guiding to sharply better second-half volumes. Cash tells the rest: $428 million from operations, $200 million of buybacks, $2 billion of liquidity, and a call Tuesday morning to explain it all — 24 hours before Alphabet and Tesla headline the week’s main event, on a day the tape was busy with index arithmetic and a chip-led rally.
Our take: The AI trade and the tariff trade get covered as rival narratives — one future, one throwback. Steel Dynamics’ quarter says they’re the same trade in different clothing: data centers sit right in the fabrication backlog’s demand list, and every hyperscaler capex dollar the market has agonized over eventually lands as somebody’s steel order. The caveat is embedded in Millett’s own credit line — the pricing strength driving these earnings is partly a policy artifact, and profits built on trade barriers last exactly as long as the barriers do. The market’s job this week is deciding what multiple policy-assisted earnings deserve versus secular ones. Chips just spent a week being repriced on that exact question; steel’s turn is coming.
What to watch
- Tuesday’s 11 a.m. ET call. The durability question: how much of the margin expansion is scrap spreads and structural demand versus tariff-supported pricing that resets if policy shifts.
- The aluminum ramp. Losses nearly halved sequentially and the third cold mill is commissioning now — if startup costs fade as guided, this is the 2027 earnings layer the market hasn’t fully priced.
- Whether the physical economy shows up elsewhere. More than 300 companies report this week. If machinery, rails, and builders echo the backlog language, the reshoring bid is broader than one steelmaker’s print.
