The Commission for Protection of Competition (CPC) in Bulgaria has approved a concentration in the fuel retail sector, allowing Uni Energy to acquire full control over Nis Petrol EOOD, BGNES reported. Following an investigation, the CPC concluded that the deal would not significantly hinder competition in the retail fuel market, where there is a horizontal overlap between the companies’ activities. The analysis of file CPC-690/2025 showed that the combined market share of Uni Energy and Nis Petrol is minimal and will remain below levels that could raise concerns about effective competition. Earlier in August, Uni Energy aimed to acquire Nis Petrol’s network of Gazprom-branded gas stations in Bulgaria, which are owned by the Serbian company NIS, controlled by Gazprom. Uni Energy is an established wholesale and retail fuel trader and a shareholder in Avia Bulgaria, which also operates gas stations in the country.
