Two of Greece’s most prominent business leaders, whose managerial credentials are widely acknowledged, appear to be aligning their strategic interests and joining forces across a number of key sectors.The executives are Yiannis Vardinogiannis of Motor Oil and Alexandros Exarchou of Aktor Group who have laid the foundations for a partnership spanning energy, liquefied natural gas (LNG) and the circular economy. The process began several months ago, when the two officicals held talks to explore potential areas of cooperation, with discussions quickly producing tangible results.The first step was the announcement of an agreement in principle for Aktor Group to acquire a 75% stake in Thalis and Helector from Motor Oil. Both companies are active in waste, wastewater and water management. Motor Oil acquired Thalis in 2022, while Helector joined the group in early 2025.The planned transaction is seen as mutually beneficial. Motor Oil will retain a 25% stake, allowing it to crystallise part of the significant value created to date while maintaining exposure to future growth. Aktor Group, meanwhile, secures a strong foothold in a sector viewed as offering substantial long-term growth potential.The second, and more strategically significant, transaction concerns the new Dioriga Gas floating LNG terminal at Agioi Theodoroi. Through the acquisition of a 50% stake, Aktor Group gains direct access to a critical energy infrastructure asset that complements its recent moves in the LNG sector and aligns with Greece’s longer-term energy cooperation with the United States. For Motor Oil, the partnership brings in a strong strategic ally for a demanding project that had previously encountered challenges but now appears to have regained momentum.Together, the two businessmen have rapidly established the foundations of what could become a significant strategic alliance with implications for Greece’s energy sector, broader economy and capital markets. Shares in Motor Oil and Aktor Group have been among the Athens stock market’s best performers this year, gaining about 49% and 44%, respectively, and trading at record highs.The rally has increased the value of Vardinogiannis’ holdings by about 1.7 billion euros since the start of the year, while Exarchou’s stake has gained roughly 900 million euros, for a combined increase of approximately 2.6 billion euros, benefiting both the two businessmen and fellow shareholders.
