State-owned Saudi Aramco bought 2.1 billion shares of Saudi Basic Industries (SABIC) on the stock market on Sunday as it completed its deal agreed last year to buy 70% of the petrochemical giant.
Four transactions were executed on the Saudi exchange, known as Tadawul, involving SABIC shares worth 259,125 billion riyals ($69.1) billion, Tadawal data showed.
The shares are being sold by the Saudi sovereign fund, the Public Investment Fund (PIF), giving it more cash to invest in the government program to diversify the economy away from oil.
Sunday's share trades involved cross transactions, also known as special deals on Tadawul, which are executed at an agreed price between a buyer and seller, without those involved.
"The deal completion is on-track with expectations to be finalized before the end of the second quarter," Aramco told Reuters in a statement when asked about the transactions. "We will make a completion announcement in due course."
Aramco has been boosting investments in refining and other downstream industries.
Three of Sunday's deals were completed at 123.40 riyals per share and the fourth at 123.20 riyals, prices that were similar to last year's agreed price of 123.39 riyals per share.
SABIC shares ended at 88.50 riyals on Sunday.
