Earnings per share for the first six months of the year reached SAR2.16, compared to SAR3.15 during the respective period last year, Yamama said.
The company cited a decrease in sales as the main reason behind the drop in its first-half net profit.
However, second-quarter net profit rose 31 per cent to SAR125.9m compared with the previous quarter, Yamama said.
