GGB vs NUE: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 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: GGB 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. GGB and NUE 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 GGB and NUE 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.

Gerdau S.A. is Brazil's largest steel producer and one of the biggest long-steel and special-steel makers in the Americas. It operates through three main segments: Brazil, North America (the United States, Canada, and Mexico), and South America (Argentina, Peru, and Uruguay), and it relies heavily on electric-arc mini-mills that recycle scrap into rebar, wire rod, merchant bars, and special steels used in construction, autos, and industry. The company also runs a Gerdau Next division targeting businesses adjacent to steel, and produces some iron ore and flat steel for its own use in Brazil.

Nucor is the largest steel producer in the United States and one of the largest in North America. The company uses electric arc furnace (EAF) technology that melts recycled scrap steel rather than traditional blast furnaces that smelt iron ore. EAF steel production has significantly lower carbon emissions than blast furnace steel and is generally lower-cost in North America given the abundance of scrap and the cost of natural gas relative to coking coal.

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

• GGB drivers: North America strength; Capital investment and modernization.
• NUE drivers: Infrastructure and reshoring demand; Carbon-advantaged production.

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: Steel is deeply cyclical, so revenue and profit can fall sharply when construction and industrial demand slow or when steel prices decline. For NUE, steel cycle volatility: the same spreads that lifted 2026 earnings can compress quickly, and analysts already model Q4 2026 EPS slightly below Q3.

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 GGB if you believe its drivers more; NUE 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 GGB and NUE guides.

GGB. Gerdau's trailing P/E near 23 is inflated by the fourth-quarter 2025 loss; on forward estimates it drops to about 8, a cyclical-value multiple that assumes analysts' expected recovery in 2026 earnings holds. The shares trade just under book value. Third-quarter results are due October 26, 2026, with consensus EPS near R$1.00 on about R$18.6 billion of revenue. Reported figures move with steel prices and the real, so trailing metrics can shift quickly across quarters.

NUE. Nucor's trailing P/E of about 21 looks high for steel because it still includes the weak second half of 2025; on 2026-2027 estimates the forward multiple is closer to 12.5, typical of a cyclical near an earnings upswing. The premium versus pure commodity peers comes from EAF cost structure, operating discipline through cycles, the 51+ year dividend growth streak, and infrastructure/reshoring exposure. Q3 2026 results are due October 26, 2026, with consensus EPS of about $5.83 on revenue of about $10.8 billion.

Headline figures (approximate, October 2026): GGB shows revenue (ttm) ~R$69.5 billion; Q2 2026 ~R$17.9 billion, up ~2% YoY, net income (ttm) ~R$2.2 billion; Q2 2026 ~R$1.45 billion, adjusted ebitda (q2 2026) ~R$3.4 billion, best since Q3 2023, margins (ttm) ~13% gross, ~13% operating, ~3% net; NUE shows revenue (ttm) ~$36 billion (+23% YoY in Q2 2026), operating margin ~16% (cyclical), net income (ttm) ~$2.9 billion, eps (ttm / 2026 consensus) ~$12.54 / ~$19.49.

GGB and NUE 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.
