Metalurgica Gerdau S.A

What it is

Metalúrgica Gerdau S.A. is the family holding company that sits above the Gerdau group, which produces and sells long steel products — rebars, wire rod, structural profiles, special steels — across Brazil, the Americas, and beyond. The operating subsidiary, Gerdau S.A., is the largest producer of long steel in the Americas, with about 13 million tonnes of annual output, and makes 71% of its steel from recycled scrap rather than raw iron ore.

The business traces back to a nail factory founded by João Gerdau, a German migrant who arrived in Rio Grande do Sul in 1869; his son Hugo later passed it to son-in-law Curt Johannpeter, who pivoted to steelmaking after the second world war. The group went public in 1970, listing on both the Rio de Janeiro and São Paulo stock exchanges.

Who owns it

Substantially all of the common shares of the company are owned by Jorge Gerdau Johannpeter and his family; non-voting preferred shares, representing a minority interest, are publicly traded. The Gerdau Johannpeter family maintains a reported 78.9% stake in Metalúrgica Gerdau S.A. — and insiders hold roughly 87.5% of all shares outstanding, leaving a free float of less than 13%.

Metalúrgica Gerdau itself operates as a subsidiary of Indac — Indústria, Administração e Comércio S.A., the family’s top-level private vehicle, meaning the Johannpeter family controls the group through two successive layers of ownership. Both Gerdau S.A. and Metalúrgica Gerdau joined B3’s Level 1 of Corporate Governance in 2001 and 2003 respectively, committing to enhanced transparency requirements.

Who runs it

André Bier Gerdau Johannpeter led the operating group until 2017, when he was succeeded by Gustavo Werneck da Cunha, a professional manager and the first non-family member to hold the chief executive role. Werneck remains CEO of Gerdau S.A. as of mid-2025, leading investor presentations alongside CFO Rafael Japur.

Rafael Dorneles Japur serves as Vice President and Investor Relations Officer of Gerdau S.A. At board level, Claudio Gerdau Johannpeter has been chairman since January 2018, and no fewer than four family members hold board positions.

The money, in plain words

Gerdau’s revenues are essentially flat — R$69.9bn (≈US$13.6bn) in FY2025, up just 4.3% from R$67.0bn (US$13.0 bn) in FY2024 (our calculation) — but what it keeps as profit has shrunk sharply. The net profit margin fell to 0.68% in FY2025 from 2.3% in FY2024 and 3.7% in FY2023 (our calculation): the company is selling just as much steel but keeping less than one cent of profit per real of revenue, squeezed by Chinese import competition and cost pressures in Brazil.

The balance sheet carries net debt of R$10.6bn (≈US$2.1bn) — total debt of R$16.6bn (US$3.2 bn) minus cash of R$6.0bn (US$1.2 bn) (our calculation) — but the group targets keeping that ratio manageable. Management has publicly committed to a financial policy of net debt no higher than 1.5 times annual operating earnings, gross debt under R$12bn (US$2.3 bn), and an average debt maturity of over six years.

The dividend yield of 3.7% still offers income even in a lean year, though the price-to-earnings ratio of 24.7× looks stretched given the compressed margins.

What it is doing now

North America ended 2025 with its highest-ever share of the group’s consolidated operating profit at 62%, reinforcing its role as the engine of the business. In Q1 2026, North American operations sustained resilient performance on solid demand and rising volumes, while Brazil was hit by more pronounced seasonality and high import levels that pressured volumes and prices.

During Q1 2026, Gerdau launched its NewEco product line, offering customers steel with a reduced carbon footprint and positioning the group to capture growing demand for lower-emission materials in construction and manufacturing. Also in 2025, the group bought out the minority partners in Gerdau Summit — a specialty-steel joint venture — from Japan’s Sumitomo Corporation and Japan Steel Works for US$32.6m, tightening control of its premium product range.

What to watch

• Chinese steel imports into Brazil. Import penetration in Brazil’s steel market hit 26.8% in Q1 2026, with China accounting for 65% of new-origin volumes and annualised imports tracking toward a fresh record of 6.3 million tonnes. This is the single biggest threat to domestic margins.
• US Section 232 tariffs. The tightening of US Section 232 steel tariffs helped rebalance North American supply and demand, boosting the group’s US operations. Management is monitoring potential changes to those tariffs and the USMCA trade review scheduled for July 2026.
• Margin recovery. A net profit margin of 0.68% at a P/E of 24.7× means the market is pricing in a rebound; any sustained cost relief or pricing improvement in Brazil would be the trigger that justifies the multiple.
• Family holding discount. Metalúrgica Gerdau (GOAU3) trades at a structural discount to Gerdau S.A. (GGBR) shares because it is one layer removed from the operating cash flows; that gap can widen or narrow with sentiment.
