Tellurian ousted its chairman and co-founder Charif Souki as an executive officer, the U.S. liquefied natural gas (LNG) developer said on Friday, weeks after auditors raised doubts about the company's ability to cover future expenses. Souki was pushed out of Cheniere Energy and co-founded Tellurian in 2016 with Martin Houston, who will replace him as chairman. Tellurian has changed its Driftwood strategy several times over the years, never attracting enough potential clients for the first, $14.5 billion phase of the 27.6 million metric ton per annum facility.
