Tellurian Inc. Stock: price and insider trades · United States

Tellurian Inc. /DE/ (ticker: TELL) was a U.S. energy company that traded on the NASDAQ in the United States before being taken over by Woodside Energy and delisted as an independent public equity story. For French-speaking investors, Tellurian was best known as a liquefied natural gas (LNG) development company rather than a conventional exploration-and-production name. Its strategy focused on building an integrated natural gas platform spanning upstream supply, gas marketing, transportation infrastructure, and LNG liquefaction/export capacity. The company was headquartered in Houston, Texas, a core hub for the U.S. oil-and-gas industry, and incorporated in Delaware. Its corporate roots date back to 1957, when it was founded as Magellan Petroleum Corporation, before a strategic transformation and renaming to Tellurian Inc. in the 2010s.

Tellurian’s flagship development was Driftwood LNG in Louisiana on the U.S. Gulf Coast. The project was designed to include an LNG terminal, associated pipelines, and supporting infrastructure aimed at securing gas supply and monetizing a large-scale export platform. In strategic terms, Tellurian pursued a vertically integrated model that was relatively uncommon among smaller U.S.-listed energy developers. The company’s investment case was built around long-duration LNG demand, infrastructure optionality, and the ability to capture value across the LNG chain. Competitively, however, Tellurian faced a difficult environment: it operated against far larger and better-capitalized LNG developers and integrated energy groups, which increased financing risk and execution complexity.
