Following the lift of the first U.S. federal government shutdown on November 12, 2025, the CFIUS review process resumed upon acceptance of filing fees. The shutdown period of 43 days has been added to the statutory 105-day review timeline.

Subsequently, the U.S. federal government entered into a second, partial and brief shutdown of three days. This additional period has also been added to the statutory review timeline.

Accordingly, of the statutory 105-day timeline, the first 90 days are currently scheduled to conclude on February 26, 2026, assuming no further developments alter the review period. The closing of the transaction will take place post receipt of CFIUS approval.

All other details, as per our letter dated June 24, 2025, remain unchanged. You are requested to kindly take the aforesaid information on record.
