The Lithuanian Supreme Administrative Court issued the ruling, which is final and not subject to appeal, last Thursday, the competition authority said.
It was Corporation of European Pharmaceutical Distributors (CEPD), a subsidiary of Pelion, that asked the court to annul the fine.
CEPD should have already paid the fine because courts earlier turned down its request to temporarily suspend the payment.
In March 2012, the Competition Council fined the company for failing to notify it in due time of its takeover of Nacionalinė Farmacijos Grupė (National Pharmaceutical Group).
CEPD in June 2010 purchased 49.99 percent of shares in Nacionalinė Farmacijos Grupė in a deal worth 24.5 million litas, thus becoming its sole shareholder. It was only in December of that year that the company notified the Competition Council of the transaction. The regulator cleared the deal in March 2011.
Pelion is quoted on the Warsaw Stock Exchange. In Lithuania, it also holds 100 percent of shares in the retail pharmacy chain Gintarinė Vaistinė, 100 percent in the pharmaceutical wholesaler Limedika, and 50 percent in Norfa pharmacies.
