CLF vs STLD: How Cleveland-Cliffs and Steel Dynamics Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: STLD is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CLF and STLD share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CLF and STLD exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Cleveland-Cliffs is North America's largest flat-rolled steel producer and the largest supplier of automotive-grade steel in the United States. It is vertically integrated, owning iron ore mines and pellet operations and converting raw materials and scrap through primary steelmaking into downstream finishing, stamping, tooling, and tubing. It makes money by selling steel to automakers, service centers, infrastructure, appliance, and other industrial customers; roughly a third of output goes to the automotive sector, and Q1 2026 steelmaking revenue included ~$1.4 billion (~29%) of direct automotive sales. The company employs roughly ~25,000 people across mining, steel, and manufacturing operations in the U.S. and Canada.

Steel Dynamics is a Fort Wayne, Indiana based steel producer and metals recycler, one of the largest in the United States. It makes steel almost entirely through electric arc furnaces (EAFs), which melt scrap rather than iron ore, a lower-cost and lower-emission model than traditional blast furnaces. The company operates across three legs: steel operations (flat-rolled, long products, and specialty shapes), metals recycling through its OmniSource network that feeds scrap into the mills, and steel fabrication (joists and decking). In 2025 it added a fourth leg by starting up a $2.7 billion aluminum flat-rolled mill in Columbus, Mississippi, aimed at the beverage-can and automotive markets.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CLF drivers: U.S.-only footprint plus tariff tailwind; Integration and scale.
• STLD drivers: Low-cost EAF steel operations; Aluminum expansion into can and auto sheet.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Cleveland-Cliffs is one of the more cyclical and leveraged names in the steel sector. For STLD, the biggest risk is cyclicality: steel and aluminum prices swing with construction, autos, and the broader economy, and a downturn can compress the price-to-scrap spread that drives profits.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CLF if you believe its drivers more; STLD if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CLF and STLD guides.

CLF. Cliffs is a deeply cyclical steelmaker, so trailing earnings and EBITDA reflect a trough rather than a steady run rate, and a simple P/E is not meaningful when the company is posting losses. Investors typically watch EV/EBITDA, leverage (net debt to EBITDA, recently elevated near or above 3x), and the path to positive free cash flow that management guided toward from Q2 2026. Figures are approximate, tied to the asOf date, and move with the steel cycle.

STLD. Steel Dynamics generated about $18.2 billion of net sales and $1.2 billion of net income in 2025, down from $1.5 billion in 2024 as steel prices eased. The first quarter of 2026 rebounded sharply, with $5.2 billion in sales and $403 million of net income on record shipments and firmer prices. At roughly $33 billion of market value the shares trade around 24 times trailing earnings, a valuation that reflects both the recent earnings rebound and the depressed base year.

Headline figures (approximate, 2026-06-27): CLF shows revenue (ttm, approx.) ~$18-19 billion, q1 2026 revenue ~$4.9 billion, q1 2026 adjusted ebitda ~$95 million (incl. ~$80M one-time energy cost), q1 2026 gaap net loss ~$229 million (~$0.42 per diluted share); STLD shows revenue (2025) ~$18.2B, net income (2025) ~$1.2B, diluted eps (2025) ~$7.99, q1 2026 net sales ~$5.2B.

CLF and STLD are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
