Gerdau (GGB) Q4 2025 earnings review
North American Strength Masks Brazilian Margin Collapse and Massive Impairment
Gerdau's 25Q4 results illustrate a severe divergence between its two primary markets. The North American segment is accelerating rapidly, achieving a 21.1% Adjusted EBITDA margin and contributing a record 73% of the company's consolidated EBITDA, buoyed by favorable pricing and resilient demand following Section 232 tariff adjustments. Conversely, the Brazilian operation is in a severe structural decline. Plagued by a 21% imported steel penetration rate and domestic oversupply, Brazil's EBITDA margin compressed for the fourth consecutive quarter, plummeting to just 7.1%. The deterioration in Brazil's outlook was so severe that management recognized a massive R$2.0 billion non-cash impairment on fixed assets, dragging the company to a reported net loss of R$1.29 billion for the quarter. Despite the accounting loss, aggressive working capital optimization generated R$1.4 billion in Free Cash Flow, funding an ongoing commitment to shareholder returns via a new 56.4 million share buyback program and signaling a strategic capital pivot away from Brazilian expansion.
🐂 Bull Case
The North American segment is accelerating, with Q4 shipments up 14% YoY and EBITDA margins expanding to 21.1%. It now acts as a massive cash engine, buffering the enterprise against domestic weakness.
Gerdau is not hoarding capital. Management distributed R$2.4 billion in 2025 (a 182% payout ratio), completed the 2025 buyback, and immediately approved a new program for up to 56.4 million shares.
🐻 Bear Case
Brazil's EBITDA fell 64.5% YoY to just R$509 million in Q4. The 7.1% margin is a staggering drop from 18.5% a year ago, proving that recent anti-dumping investigations and tariff increases have failed to stem the bleeding.
The write-off of fixed assets in Brazil explicitly assumes a 'deterioration in economic conditions at a magnitude greater than considered in previous periods.' Management's internal outlook for the domestic market is highly pessimistic.
⚖️ Verdict: ⚪
Neutral. The North American operations are exceptionally strong and working capital management is excellent. However, the sheer scale of the profit collapse and asset impairment in Brazil makes it impossible to view this quarter as a clear win. The company is fundamentally re-rating as a US-centric steel producer.
Key Themes
Structural Asset Impairment in Brazil
Gerdau recorded a massive R$1.96 billion non-recurring impairment charge in 4Q25, primarily tied to fixed assets in Brazil. This is a critical red flag. The write-off was driven by discounted cash flow projections and capacity utilization reviews that reflect a 'deterioration in economic conditions.' This confirms that the weakness in Brazil is no longer viewed as a temporary cyclical dip, but a structural reset of earning power.
North America Trade Defense Dividends
The implementation of Section 232 tariff adjustments in the U.S. continues to yield massive dividends. North America shipments surged 13.9% YoY to 1.22M tonnes in 4Q25, while Gross Profit in the segment leaped 172% YoY to R$1.55 billion. The order backlog remains elevated at 85 days (above the ~70-day recent average), driven by non-residential construction and data centers.
Brazilian Import Flood Defies Tariffs
Despite recent government interventions (a direct tariff increase of 25% covering 9 NCMs and preliminary anti-dumping rulings), imported steel penetration remained stubbornly high at 21% in 4Q25. Full-year imports hit a record 6.4 million tonnes (+7.4% YoY), driving massive oversupply and crushing domestic flat and long steel pricing.
CAPEX Slash Signals Strategic Pivot
Management is sharply decelerating capital expenditures. After spending R$6.1 billion in 2025, the Board approved a dramatically lower CAPEX plan of R$4.7 billion for 2026. Furthermore, 'Maintenance' CAPEX is modeled at just R$3.0 billion/year for the next five years. This capital starvation strategy in Brazil aligns with the narrative of retreating from a structurally compromised domestic market to harvest cash.
Miguel Burnier Mining Platform Nears Completion
A key operational driver for 2026 will be the Miguel Burnier Sustainable Mining platform. Reaching 91% physical progress in 4Q25, the project has entered integrated testing. Once ramp-up is completed over the next 12 months, it will add 5.5 million tonnes/year of iron ore capacity, acting as a crucial cost-reduction lever for the Ouro Branco mill.
South America Margins Compressing
The South America segment (Argentina, Peru, Uruguay) is deteriorating. Despite a 9.5% YoY increase in shipments (fueled by Argentine exports), intense pricing pressure drove Net Sales down 13% YoY. Cost of goods sold jumped 12% QoQ due to maintenance shutdowns, driving Adjusted EBITDA down 25.7% QoQ to R$174 million.
Other KPIs
Accelerating significantly from R$1.0 billion in 25Q3. This was almost entirely driven by a massive working capital release of R$1.36 billion as the company optimized raw material inventories and reduced capacity in Brazil to match lower demand. YoY FCF looks higher, but last year's figure was distorted by judicial deposits.
Reversing the peak seen in Q3. Gross debt fell 23.9% QoQ from R$18.64B, driven by the early redemption of the US$510M 2030 Bond and short-term debt settlements. The company maintains a highly liquid position with R$6.37B in cash and a fully available US$875M global revolving credit facility.
Guidance
Decelerating significantly. This represents a 23% reduction compared to the R$ 6.1 billion spent in FY25. The reduction reflects the completion of major cycles like the Miguel Burnier mine and Ouro Branco hot-rolled coil line, but also a disciplined pullback from deploying growth capital into the currently uncompetitive Brazilian market.
Stable baseline. Management expects to allocate roughly R$3 billion annually purely to maintain existing assets and extend useful life, setting a clear baseline for calculating future free cash flow generation.
Key Questions
Impairment Mechanics and Floor
Regarding the R$2.0 billion impairment in Brazil: Which specific industrial units were written down, and what is the new long-term EBITDA margin assumption embedded in the discounted cash flow models that triggered this charge?
Brazil Margin Trajectory
Brazil's EBITDA margin compressed to 7.1% in Q4. With the new 25% import tariff on 9 NCMs in place, do you anticipate this margin has bottomed, or will typical Q1 seasonality and lingering inventory overhangs cause further compression?
North America Sustainability
North American margins reached an exceptional 21.1%. How much of this is structural due to an improved product mix (downstream/data centers) versus a temporary pricing premium created by the latest wave of trade defense?
Buyback Execution Pace
You've authorized a new 56.4 million share buyback program. Given the sharp reduction in 2026 CAPEX and strong FCF generation, should investors expect an accelerated execution pace for this program compared to 2025?
