AI summary

Hindalco's step-down wholly owned subsidiary Aditya Holdings is acquiring US-based AluChem Companies. The deal awaits CFIUS (US foreign investment review) clearance. Two US government shutdowns, one lasting 43 days and another of 3 days, have paused and extended the 105-day statutory review. The first 90 days of review are now scheduled to end on February 26, 2026. Deal closing will follow once CFIUS approval is received. No other terms have changed from the original June 24, 2025 intimation.

Likely market impact

Acquisition still pending US regulatory approval; review timeline stretched by federal shutdowns. Investors await CFIUS clearance for deal closure.
