The US authorities had given the Russian tycoon Oleg Deripask until December 12 to reduce their holdings in these three companies, but stated in a statement that the deadline had been postponed until January 2019.
In April, the US Treasury Department imposed sanctions on Rusal and other countries associated with Deripasku, but has since repeatedly resumed several times as authorities review the blacklist.
According to a statement posted on the website of the US Treasury Department, the Friday movement extends the licenses that apply to authorized companies to allow for the activities required to operate or contract. It also extends licenses to allow transactions necessary to clear debts, equity and other equity.
Rusal, En + and GAZ refused to comment.
