Is GGB a Buy or a Sell? The Bull and Bear Case (2026)
Last updated July 2026
Short answer
Both cases are real, which is why the question is contested. The bull case for GGB (GGB) rests on North America strength: Gerdau's North American segment delivered rising shipments and a meaningful EBITDA increase in 2025, benefiting from steady construction and industrial demand and healthy mill utilization. The bear case rests on steel is deeply cyclical, so revenue and profit can fall sharply when construction and industrial demand slow or when steel prices decline. Analysts covering it publish targets from $5.27 to $5.98 against a $4.87 price, so even the professionals disagree by 13% of their own average. We do not give a verdict. What follows is each case at full strength, so you can decide which set of assumptions you actually believe. Walnut is not an investment adviser.
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. As an ADR, GGB gives US investors exposure to a cyclical, commodity-linked business whose earnings move with steel prices, construction and industrial demand, scrap and energy costs, and the Brazilian real. In 2025, strong North American demand and higher shipments offset weakness in Brazil, where record steel imports pressured margins. The stock is generally viewed as a value-oriented, dividend-paying way to play the steel cycle, with results that can be lumpy from quarter to quarter depending on regional conditions and pricing.
The bull case: what would have to be true for $5.98
The most optimistic published target on GGB is $5.98, +22.8% from the $4.87 price as of July 2026. Getting there needs the following to work close to its best case, not merely to avoid going wrong.
1. North America strength
Gerdau's North American segment delivered rising shipments and a meaningful EBITDA increase in 2025, benefiting from steady construction and industrial demand and healthy mill utilization. Continued US infrastructure and reshoring activity, plus trade protections on imported steel, support this region as a key earnings pillar.
2. Capital investment and modernization
The company approved roughly R$4.7 billion in capital expenditure for 2026, funding capacity, efficiency, and modernization projects. These investments aim to lower costs and improve competitiveness in its mini-mill footprint, though they also absorb free cash flow in the near term.
3. Shareholder returns and cyclicality
Gerdau pays regular dividends and has a history of returning cash to shareholders when the cycle is favorable. The mini-mill, scrap-based model is relatively flexible on volumes, which can help the company manage downturns better than some integrated peers.
4. Brazil recovery potential
The Brazil segment was pressured in 2025 by record import volumes and weaker margins. Any tightening of import controls, a firmer domestic construction market, or better steel pricing in Brazil could restore a large portion of earnings that is currently depressed.
The bear case: what would have to be true for $5.27
The most pessimistic published target is $5.27, +8.2% from the current price. That is not a floor and not a forecast; it is roughly what one analyst thinks GGB is worth if the risks below bite instead of the drivers above.
Steel is deeply cyclical, so revenue and profit can fall sharply when construction and industrial demand slow or when steel prices decline. Brazilian operations face intense competition from imports (which hit record volumes in 2025) and from domestic rivals, compressing margins. As a Brazilian ADR, GGB carries currency risk from the real, plus Brazilian political, tax, and regulatory exposure that can affect reported dollar results. Scrap, energy, and iron-ore input costs are volatile, and heavy capital spending can weigh on free cash flow in soft years. Trade policy and tariffs in North America can cut both ways for demand and pricing.
The bear case deserves the same attention as the bull case, and usually gets less. If you are holding GGB already, the question is not whether these risks exist but whether any of them has moved from possible to actually happening in the reported numbers.

How is GGB valued? (as of July 2026)
Snapshot for GGB as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue (TTM): ~$13 billion (roughly R$70 billion for 2025)
- Net income (TTM): ~$560 million
- Adjusted EBITDA (2025): ~R$10.1 billion (down ~7% YoY)
- Market cap: ~$8 to 9 billion
- P/E ratio: ~14 trailing, ~9 forward
- Dividend yield: ~2.5%
Gerdau trades at cyclical-value multiples, with an EV/EBITDA around 6 and a low double-digit trailing P/E that compresses further on forward estimates. Steel shipments grew about 6% to roughly 11.6 million tonnes in 2025, but weaker Brazil margins pulled adjusted EBITDA down modestly for the year. Reported figures move with steel prices and the real, so trailing metrics can shift quickly across quarters.
How do you decide if GGB is a buy?
Rather than asking whether GGB is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the bull case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold GGB indirectly through an index or sector ETF before adding more.
What would change your mind on GGB
Write the tripwires down before you need them. Deciding what would falsify your view is far harder once a position is moving against you.
- Bull case breaks if: North America strength stalls in the reported numbers rather than in the narrative around them.
- Bear case breaks if: steel is deeply cyclical, so revenue and profit can fall sharply when construction and industrial demand slow or when steel prices decline fails to materialise over several reporting periods while the drivers keep compounding.
- Neither matters if: the position has grown large enough that being wrong would damage the whole portfolio. Sizing overrides the argument.

FAQ
Is GGB a good stock to buy right now?
+
That depends on which case you find more convincing, and both are on this page. The bull case rests on North America strength, with revenue (ttm) at ~$13 billion (roughly R$70 billion for 2025). The bear case rests on steel is deeply cyclical, so revenue and profit can fall sharply when construction and industrial demand slow or when steel prices decline. Analysts covering it are spread from $5.27 to $5.98, which is itself a signal that this is genuinely contested. If you believe the thesis, the real questions become sizing and overlap rather than timing. Walnut is not an investment adviser and this is not a recommendation.
Should I sell GGB?
+
Nobody can answer that for you, and the honest version of the question is narrower: has anything changed in the reason you bought it? The bear case on this page is the place to check. Steel is deeply cyclical, so revenue and profit can fall sharply when construction and industrial demand slow or when steel prices decline. If that risk is what you were worried about and it is now playing out, that is a real signal. If the price simply fell while the thesis held, that is a different situation entirely. The most pessimistic published target is $5.27, +8.2% from the $4.87 price, which is one analyst's downside case rather than a floor. Walnut is not an investment adviser.

What would have to change for GGB to stop being worth holding?
+
Decide that in advance, because it is far harder to think clearly once a position is moving against you. The concrete tripwires here: the driver behind the bull case (North America strength) stalling in the reported numbers rather than in the narrative, the risk above (steel is deeply cyclical, so revenue and profit can fall sharply when construction and industrial demand slow or when steel prices decline) turning from a possibility into a reported fact, or the position growing large enough that a bad outcome would matter to your whole portfolio regardless of who is right.
