AI summary

A fire on September 16, 2025 at Novelis Inc.'s Oswego plant in New York led to extensive restoration work. The hot mill is expected to restart by end-December 2025, followed by a four to six week production ramp-up. Novelis is a wholly owned subsidiary of Hindalco.

Likely market impact

The restart schedule may reduce prolonged disruption, but the financial impact is not quantified and production remains uncertain until the ramp-up is complete.
