CBA posted a net loss of R$ 164 million ($31M) in Q4 2025, nearly tripling the year-ago loss of R$ 56 million, as accounting effects from energy futures contracts and foreign-exchange hedging instruments overwhelmed operating improvements.
Adjusted EBITDA fell 47% year-over-year to R$ 257 million ($49M) but rose 10% sequentially from Q3, signaling the beginning of an operational recovery after a turbulent year disrupted by alumina refinery outages.
LME aluminum averaged US$ 2,827 per tonne in Q4, up 10% year-over-year and near a three-year high, yet elevated production costs and a rising Selic rate prevented the price rally from reaching the bottom line.
What Happened at CBA in Q4 2025
What Happened
Companhia Brasileira de Alumínio — CBA (B3: CBAV3), Brazil’s largest integrated aluminum producer and a subsidiary of Votorantim S.A., reported a net loss of R$ 164 million ($31M) for the fourth quarter of 2025, a 193% increase over the R$ 56 million loss posted a year earlier. Net revenue slipped 4% year-over-year to R$ 2.2 billion ($422M).
The company attributed the widening accounting loss to non-cash mark-to-market effects on energy futures contracts and financial instruments used to hedge export revenues — items that eroded the reported bottom line without immediate cash impact. CEO Luciano Alves emphasized that operationally, the quarter continued a recovery trajectory that began in the second half of the year.
Adjusted EBITDA came in at R$ 257 million ($49M), down 47% year-over-year but up 10% sequentially from Q3’s R$ 234 million. The sequential improvement is notable given the persistent margin pressure CBA has faced since alumina refinery outages disrupted production in the first half of 2025.
Key Drivers Behind CBA’s Q4 2025 Results
Key Drivers
Aluminum Pricing and Market Dynamics
The average LME aluminum price reached US$ 2,827 per tonne in Q4, up 10% year-over-year and 8% from Q3, driven by US rate cuts and stronger global commodity demand. CEO Alves described the current price level as “quite healthy for the industry.”
The price environment should have been a tailwind for CBA, but the benefits were diluted by elevated production costs that the company has been working to bring under control since the alumina refinery disruptions of early 2025. Production normalization was expected to stabilize only in Q4 2025, and CBA confirmed that its operations are now “in a much better situation” than during the crisis period.
Sales Volume and Segment Performance
Total aluminum sales reached 128,000 tonnes in Q4, up 2% year-over-year but down 3% sequentially due to seasonal softness. Primary aluminum was the bright spot, with volumes rising 8% annually to 71,000 tonnes on higher P1020 ingot sales.
Transformed products volumes declined 8% year-over-year to 32,000 tonnes, reflecting a more moderate pace of industrial consumption in the final months of the year. Recycling volumes were roughly flat annually at 25,000 tonnes but slipped 4% sequentially, reflecting weaker demand from the self-construction and credit-sensitive segments.
The mix shift toward lower-margin primary products and away from higher-value-added transformed aluminum partially explains why higher LME prices did not translate into proportional revenue gains.
Accounting Effects and Financial Result
The net financial result was negative R$ 153 million ($29M), an improvement of R$ 264 million versus Q4 2024. However, the overall bottom line was dragged down by non-cash accounting charges related to energy futures mark-to-market and export hedging instruments.
These items create volatility in the reported net income line but do not represent immediate cash outflows. CBA flagged this distinction explicitly in its results commentary, suggesting management views the underlying operational trajectory more favorably than the headline loss suggests.

Financial Detail
EBITDA and Margin Trajectory
The adjusted EBITDA margin compressed sharply on a year-over-year basis. Adjusted EBITDA of R$ 257 million ($49M) on R$ 2.2 billion ($422M) revenue implies an approximately 12% margin, down from roughly 22% in Q4 2024 when the company posted EBITDA near R$ 485 million. The sequential improvement from Q3’s R$ 234 million, however, marks the second consecutive quarter of recovery after the Q2 trough of R$ 189 million.
The EBITDA trajectory across 2025 tells a clear story: Q1 at R$ 430 million ($82M), a sharp Q2 collapse to R$ 189 million ($36M) driven by the alumina refinery crisis, then gradual recovery through Q3 and Q4. If the normalization holds, 2026 should see a meaningfully different operating profile.
Leverage and Debt Position
Gross debt ended Q4 at R$ 3.2 billion ($613M), essentially flat versus Q3. Net debt-to-EBITDA leverage rose to 2.97x, up from 2.45x at the end of Q3, reflecting the lower trailing twelve-month EBITDA rather than a deterioration in the absolute debt level.
CFO Camila Abel indicated that the debt quantum was “practically stable” versus the prior quarter and that leverage should decline over 2026 as EBITDA normalizes to higher run-rate levels. The company’s average debt term of 5.5 years and dollar-denominated average cost of 5.7% provide some cushion, but at a 15% Selic rate, refinancing costs in the local market remain elevated.
Management Signals from CBA
CEO Luciano Alves stated the company has undergone “a very good recovery process” and is “in a much better situation” than during the alumina crisis of early 2025. He described the current LME aluminum price level of around US$ 2,800 per tonne as “quite healthy for the industry.”
CFO Camila Abel signaled that gross debt was essentially unchanged from Q3 and that leverage should come down through 2026 as EBITDA operates at a “normalized level.” The framing suggests management expects a materially higher EBITDA run-rate in coming quarters.
The company emphasized that the Q4 accounting loss was driven by non-cash effects from energy futures and FX hedging instruments, with no immediate cash impact. The distinction between reported losses and operating cash generation is a recurring theme in CBA’s recent earnings communications.
What to Watch Next for CBA
What to Watch Next
The Q1 2026 report will be the critical data point. Management has been guiding for cost normalization by early 2026 following the alumina refinery stabilization, and the combination of higher LME prices, lower alumina costs, and a stronger BRL (which reduces dollar-denominated debt when converted) should provide a meaningful EBITDA inflection if production operates at steady state.
The Rondon bauxite project remains a potential catalyst. CBA has reported increased interest from partners due to global bauxite supply concerns, and any partnership announcement would monetize a long-dormant asset. The development of rare-earth mineral extraction is a secondary optionality that is not yet in consensus estimates.
US tariff policy remains a wild card. CBA has historically exported aluminum to the United States, and the February 2026 rollout of a 10% global import tax may redirect trade flows. Management noted in prior quarters that it compensated for reduced US volumes by shifting to domestic and European markets, but any escalation could pressure export margins further.

Key Risks for CBA Going Forward
Risks
Leverage is the most immediate concern. At 2.97x net debt-to-EBITDA, CBA is near the upper bound of comfort for an industrial cyclical. If EBITDA recovery stalls — whether due to another production disruption, falling aluminum prices, or persistent BRL strength reducing export competitiveness — the leverage ratio could breach 3x and pressure credit ratings.
Energy costs remain structurally elevated. CBA is self-sufficient in electricity through its own hydroelectric plants, but contracted energy purchases at above-market rates have weighed on margins throughout 2025. The acquisition of wind energy assets should diversify the matrix, but cost benefits will be gradual.
Global trade policy is a persistent overhang. The EU’s Carbon Border Adjustment Mechanism takes effect in 2026, which could create opportunities for CBA’s low-carbon aluminum, but US tariffs and the broader fragmentation of trade flows introduce uncertainty into export volumes and pricing.
BRL appreciation is a double-edged sword. A stronger real reduces dollar-denominated debt when converted, but it also compresses the BRL-equivalent of dollar-priced aluminum sales, creating a headwind to revenue and margins even when LME prices are rising. The BRL has strengthened roughly 9% against the dollar over the past twelve months.
Sector Context for Brazil’s Aluminum Industry
LME aluminum prices hit a three-year high in late 2025, trading in the US$ 2,800–2,900 per tonne range through November before pulling back slightly. The rally was driven by a combination of US monetary easing, strong demand from the electric vehicle and energy transition sectors, and tight global supply as Chinese smelter capacity approached its regulatory ceiling.
CBA, as a vertically integrated producer with its own bauxite mines, alumina refinery, smelting capacity, and hydroelectric power, occupies a unique position in this market. Its low-carbon credentials — with an S&P Global sustainability score of 74/100, some 32 points above the industry average — could become a competitive advantage as the EU’s CBAM raises the cost of importing high-carbon aluminum into Europe.
Banco Safra upgraded CBA to Buy in late 2025, setting a price target of R$ 7.30 for year-end 2026 and projecting EBITDA of R$ 1.5 billion for 2026 — nearly triple the annualized run-rate implied by Q4. CBAV3 shares have rallied roughly 86% over the past twelve months to around R$ 10.21, suggesting the market is already pricing in a meaningful operational recovery.
