Norsk Hydro’s Alunorte alumina refinery in Pará, Brazil, has begun ramping up production to full capacity following a breakthrough in its natural gas supply negotiations. The operational recovery comes after Brazil’s oil, natural gas and biofuels regulator, ANP, approved Alunorte’s status as a self-importer of gas. This regulatory clearance enabled the company to reach a temporary agreement with its gas supplier, CELBA, regarding direct access to the Barcarena LNG receiving and regasification terminal.

The production ramp-up reverses the earlier contingency measure that had forced Alunorte to cut output to 50 percent. That reduction was implemented after CELBA, a subsidiary of the New Fortress Group, notified Norsk Hydro of supply disruptions stemming from issues with its infrastructure and financial situation. With the new access agreement in place, the refinery is now restoring volumes, although the company continues to pursue a long-term solution to secure stable gas supplies.

Operational Recovery and Output Loss

While production is returning to normal levels, the disruption has resulted in tangible volume losses. Norsk Hydro estimates that lost alumina production during the period of reduced output stands at 100,000 to 120,000 tonnes. This figure represents the cumulative impact of the supply interruption before the temporary terminal access deal was finalized.

The financial implications of the disruption remain aligned with earlier estimates. The potential impact on Norsk Hydro’s Bauxite & Alumina segment for Q3 2026 is projected at USD 75 to 100 million. This estimate accounts for both the revenue loss from the reduced output and the additional costs incurred from purchasing spot gas at prices above the contracted rate.

Strategic Context

The resolution of the immediate supply crisis through temporary terminal access highlights the critical dependency of alumina refining on consistent energy inputs. By securing ANP approval to act as a self-importer, Alunorte has gained leverage to bypass bottlenecks within CELBA’s infrastructure. However, the need for a temporary agreement underscores that long-term supply security remains unresolved. Norsk Hydro continues efforts to secure alternative long-term gas supplies while preserving its rights under the existing Gas Supply Agreement with CELBA.

What the Numbers Show

The quantification of lost production at 100,000 to 120,000 tonnes provides a concrete measure of the operational downtime caused by the gas supply disruption. When viewed alongside the USD 75 to 100 million financial impact estimate, it illustrates the high cost of energy insecurity in the alumina value chain. The dual pressure of volume loss and premium spot gas pricing suggests that while operational stability is returning, margin recovery for the Bauxite & Alumina segment will depend on the duration of the temporary arrangement and the speed at which long-term alternative supplies are secured.

Norsk Hydro reported adjusted EBITDA of NOK 8,923 million for the second quarter of 2026, an increase from NOK 7,790 million in the same quarter last year. The growth was driven by higher aluminium prices and product premiums, alongside improved earnings in the recycling business. However, lower energy production due to hydrology and adverse effects from a stronger Norwegian krone negatively impacted the results. The company achieved strong profitability, with adjusted earnings per share rising to NOK 2.2 from NOK 1.7 in the second quarter of 2025. Free cash flow for the quarter was NOK 4 billion, and the twelve-month adjusted return on capital employed (RoaCE) ended at 10.9 percent.

President and CEO Eivind Kallevik highlighted the operational strength and market opportunities, noting that the agreement to restart Slovalco is a significant step for European aluminium capacity. The company announced the planned restart of 75,000 tonnes of capacity at the Slovalco smelter during the second half of 2026, following a long-term framework agreement with the Slovak government.

Operational Highlights

Hydro's upstream businesses demonstrated continued strong performance. Alunorte saw year-on-year productivity increases, while the ramp-up of previously curtailed capacity at Norwegian smelters contributed to higher production volumes. The recycling business delivered robust results, particularly in North America, with adjusted EBITDA exceeding NOK 900 million. Additionally, the company secured a further 5 TWh of power sourcing in the second quarter.

Business Area Performance

Adjusted EBITDA for Bauxite & Alumina decreased primarily due to lower alumina prices and a stronger Brazilian real. Energy results fell due to lower production and a loss on price area differences. Conversely, Aluminium Metal saw significant growth driven by higher all-in metal prices and lower alumina costs. Metal Markets declined due to lower trading results, while Extrusions improved on higher recycling margins.

Financial Position and Outlook

Net income for the quarter amounted to NOK 5,965 million, which included unrealized derivative gains of NOK 3,088 million and various impairment charges. Net debt increased from NOK 12.9 billion to NOK 16.3 billion, mainly due to dividends paid and investments. Hydro also entered a five-year supply agreement with Nexans for 85,000 tonnes of low-carbon aluminium wire rod and signed a 10-year power agreement with Eviny covering 0.5 TWh annually from 2031 to 2040.

The company reported quarterly sales of $5.983 billion, beating the analyst consensus estimate of $5.380 billion by 11.21 percent. This represents a 14.62 percent increase over sales of $5.220 billion in the same period last year. Adjusted earnings per share were $0.23, missing the analyst consensus estimate of $0.25 by 8 percent. This is a 43.75 percent increase over earnings of $0.16 per share from the same period last year.
