Exhibit 99.1

Corporate July 2019 presentation

Cautionary statements Forward-looking statements Plans for the Permian Global Access Pipeline, Haynesville Global Access Pipeline and Delhi Connector Pipeline projects discussed herein are in the early stages of development and numerous aspects of the projects, such as detailed engineering and permitting, have not commenced. Accordingly, the nature, timing, scope and benefits of those projects may vary significantly from our current plans due to a wide variety of factors, including future changes to the proposals. Although the Driftwood pipeline project is significantly more advanced in terms of engineering, permitting and other factors, its construction, budget and timing are also subject to significant risks and uncertainties. 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, expected partners and customers, the parties’ ability to complete contemplated transactions (including, where applicable, to enter into definitive agreements related to those transactions), margins, returns and payback periods, future assets, cash flows, production, delivery of LNG, required infrastructure, future costs, prices, financial results, equity values, liquidity and financing, including equity funding and debt syndication, regulatory and permitting developments, construction and permitting of pipelines and other facilities, reaching FID, 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. Projected future cash flows as set forth herein may differ from cash flows determined in accordance with GAAP. We may not be able to complete the anticipated transactions described in the presentation. FID is subject to the completion of financing arrangements that may not be completed within the time frame expected or at all. Achieving FID will require substantial amounts of financing in addition to that contemplated by the agreements between Total and Tellurian discussed in this presentation, and Tellurian believes that it may enter into discussions with potential sources of such financing and Total in order to achieve commercial terms acceptable to all parties. Accordingly, final agreements may have terms that differ significantly from those described in the presentation. 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. The financial information included on slides 6, 16, 19-21 and 28 is meant for illustrative purposes only and does not purport to show estimates of actual future financial performance. The information on those slides assumes the completion of certain acquisition, financing and other transactions. Such transactions may not be completed on the assumed terms or at all. Actual commodity prices may vary materially from the commodity prices assumed for the purposes of the illustrative financial performance information. 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. Reserves and resources Estimates of non-proved reserves and resources are based on more limited information, and are subject to significantly greater risk of not being produced, than are estimates of proved reserves. 2
