Mr Rigas is the founding shareholder and CEO of Energean, having led the company since its inception in 2007.

A Petroleum Engineer with a background in investment banking, Mathios has been instrumental in shaping Energean into a leading independent, gas-focused exploration and production company. Under his leadership, Energean has successfully expanded internationally through strategic acquisitions. Since 2007, Energean’s oil and gas reserves have grown exponentially from just 1 million boe to over 1 billion boe in 2024, while production has surged from 1,000 barrels per day at Prinos in 2007 to approximately 150,000 boe per day in 2024.

Today, Energean stands as a robust and resilient company. The company has secured a long-term, 20-year commercial position in Israel, underpinned by $20 billion in contracted gas sales—enhancing both energy security and market competition in the region. Mathios has also been a driving force behind Energean’s industry-leading ESG strategy, earning multiple European awards for sustainability and environmental responsibility. In 2019, he became the first E&P CEO to commit to a net-zero strategy.

His leadership has been widely recognised: in 2018, he was named CEO Year in London, Energean was awarded Independent of the Year, and the company’s IPO was honoured as Deal of the Year by the World Energy Council. Before founding Energean, Mathios had over two decades of experience in investment banking and private equity. He worked with J.P. Morgan and its predecessor banks in London before establishing Capital Connect, a Greek private equity fund.

Mathios holds a degree in Mining and Metallurgical Engineering from the National Technical University of Athens and an MSc/DIC in Petroleum Engineering from Imperial College London.
