Gerdau Q3 EBITDA Margin Reaches 20.2%, But Brazil Drag Persists

What happened

Gerdau reported Q3 2026 EBITDA of BRL 3.8 billion at a 20.2% margin, its best since Q2 2023, driven by robust North American demand and operations. The result confirms the North America engine remains strong, but Brazil continues to pressure consolidated profitability, as import penetration and pricing remain unresolved. The Q3 print slightly exceeds the base-case assumption of a 20%+ North America margin, but it does not yet show the Brazil recovery needed to justify a rerating. Management's three 2H26 projects and any Brazilian trade-defense rulings are still the key swing factors for sustained margin improvement. At the current price around $5.10, the stock already prices a broad steel recovery, leaving limited room for error if North America backlogs cool or Brazil trade remedies disappoint.

Implication

Investors should monitor North America backlog days and margin trends in the next quarterly release; a decline toward 70 days would signal the profit engine is normalizing. Brazil's anti-dumping rulings on wire rod and HRC must produce binding duties or quotas to lift the segment's EBITDA margin above 10%. The 2H26 project start-ups at Miguel Burnier, Pindamonhangaba, and Midlothian need to convert into visible EBITDA and free cash flow. With free cash flow minimal in 1Q26 and heavy 2026 capex of R$4.7 billion, the company's ability to fund dividends and buybacks organically is unproven. A sustained close above the $5.80 trim level or a confirmed Brazil catalyst would warrant reconsideration, but until then the risk/reward skews neutral.

Thesis delta

No material change to the WAIT thesis. Q3's 20.2% consolidated margin validates North America strength but does not address the key uncertainty: Brazil's import-driven margin compression. The base-case valuation of $5.20 remains intact, and the report's triggers (Brazil remedies, project execution) are unchanged.
