Bigger capacity, greater impact? Assessing if Novelis faces a deeper fiscal blow from Oswego fire than Sierre flood

History has a way of repeating itself for Novelis; and this time, it has done so in barely a year. During the second quarter of FY2025, Novelis endured financial and operational stress due to a severe flood at its Sierre plant in Switzerland. Cut to Q2 FY2026, Novelis again finds itself in a similar situation due to a fire outbreak at its Oswego plant in New York. While the timing of the incident was just two weeks before the quarter-end, it reflected not much effect on its Q2 financial results. But Novelis and its parent company Hindalco are embracing a negative impact on cash flow by about USD 550-650 million for FY2026, which also includes an estimated adjusted EBITDA loss of USD 100-150 million - a figure that signals the gravity of the operational disruption.

The Oswego plant, currently halted, is among Novelis’ key assets with an annual production capacity of 400,000 tonnes, notably higher than the 250,000 tonnes capacity of the Swiss Sierre plant that was forced offline for three months due to flooding last year. Novelis anticipates a similar timeline for Oswego’s recovery, expecting operations to resume by December 2025. The magnitude of financial stress could be similar or more, considering the larger capacity of Oswego. Consequently, the financial loss could escalate proportionally, making each week of downtime significantly more expensive. For the repairing of Sierre plant last year, Novelis reported a net expenditure of USD 21 million, in addition to USD 61 million in flood-related charges.

A strong quarter, shadowed by uncertainty ahead
