Exhibit 99.1

Tellurian business update September 2019

Cautionary statements The information in this presentation includes “forward - looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact are forward - looking statements. The words “anticipate,” “assume,” “believe,” “budget,” “estimate,” “expect,” “forecast,” “initial,” “intend,” “may,” “model,” “plan,” “potential,” “project,” “should,” “will,” “would,” and similar expressions are intended to identify forward - looking statements. The forward - looking statements in this presentation relate to, among other things, future contracts and contract terms, the commencement of construction at Driftwood and the timing thereof, and future demand and supply affecting LNG and general energy markets and other aspects of our business and our prospects and those of other industry participants. Our forward - looking statements are based on assumptions and analyses made by us in light of our experience and our perception of historical trends, current conditions, expected future developments, and other factors that we believe are appropriate under the circumstances. These statements are subject to numerous known and unknown risks and uncertainties which may cause actual results to be materially different from any future results or performance expressed or implied by the forward - looking statements. These risks and uncertainties include those described in the “Risk Factors” section of our Annual Report on Form 10 - K for the fiscal year ended December 31, 2018 and our other filings with the Securities and Exchange Commission, which are incorporated by reference in this presentation. Many of the forward - looking statements in this presentation relate to events or developments anticipated to occur numerous years in the future, which increases the likelihood that actual results will differ materially from those indicated in such forward - looking statements. We may not be able to enter into definitive agreements with Petronet LNG on the terms contemplated in the MOU, or with the other parties on slide 8 on the terms contemplated, or at all. Commencement of construction will require substantial amounts of financing in addition to that contemplated by the MOU and related agreements, and Tellurian believes that it may enter into discussions with potential sources of such financing and Petronet LNG in order to achieve commercial terms acceptable to all parties. Accordingly, the definitive agreements contemplated by the MOU, if entered into, may have terms that differ significantly from those set forth in the MOU. The forward - looking statements made in or in connection with this presentation speak only as of the date hereof. Although we may from time to time voluntarily update our prior forward - looking statements, we disclaim any commitment to do so except as required by securities laws. Forward - looking statements 2
