AI summary

Hindalco Industries is providing its fourth status update on the proposed acquisition of AluChem Companies, Inc. by its step-down subsidiary Aditya Holdings LLC. The deal requires approval from CFIUS (the US government's foreign investment review body). The CFIUS review process has been delayed because statutory timelines were tolled due to a partial shutdown of the US federal government. As a result, CFIUS has granted an additional extension, pushing the review completion deadline to July 2, 2026. The company has filed the necessary documentation and will provide further updates upon material developments or completion of the review.

Likely market impact

The acquisition remains on track but faces regulatory timeline delays due to US government operations. This is a procedural pause, not a deal cancellation, though it pushes the expected closing date beyond the previous timeline.
