Russia's competition watchdog has approved Pharmacy Chain 36.6's purchase of the Russian business of Finnish drug retail and wholesale chain Oriola-KD.
Timur Shkaya, Pharmacy Chain 36.6's co-owner, told Reuters on Friday the company planned to close the deal on Monday.
The purchase, valued at up to 100 million euros ($123 million), was approved by Russia's Anti-Monopoly Service (FAS), he said.
Oriola-KD took a $100 million impairment charge in June due to weaker growth prospects in Russia.
Russia's economy has been hit by Western sanctions over Moscow's role in the Ukraine conflict.
Oriola-KD generated around 1 billion euros in sales in Russia last year. It owns the 03-Apteka and Stary Lekar drug store chains, as well as distributor Oriola.
