Tellurian executive summary 5 Tellurian has sold all the necessary offtake for Driftwood Phase I (two-plants/11 mtpa)(1) .. Definitive, binding agreements with Gunvor, Vitol and Shell for 9.0 mtpa .. The addition of Shell brings the world’s largest LNG portfolio and the largest buyer of U.S. LNG into the Driftwood project .. $12 bn. in development costs has the potential to generate $5 bn. in operating cash flow/yr. at strip prices Commencing debt finance process: continuing to position for 1Q22 FID .. Tellurian has started site preparation and begun the debt financing process for Driftwood .. Process underway with several upstream counterparties to expand our footprint in gas production .. Tellurian is debt free and expects to double exit rate gas production revenues from 2020 to 2021 LNG macro: strong demand, low inventories and carbon premium is leading to record LNG prices .. EU carbon prices are up ~110% over the last year; coal + carbon is the new floor for European gas pricing .. JKM 2-year strip is up ~83% over the past year; a clear call on new supply with Asian demand growing 11% YTD .. Global net zero goals are leading to targeted coal phaseouts, supporting long-term gas demand ESG is a core attribute of the Tellurian offering .. Upstream production allows tracking and certification of GHG emissions along the value chain .. Tellurian’s upstream operations use “green completions” to eliminate flaring and minimize methane leakage .. RSG: Tellurian is examining several initiatives that would certify produced natural gas as “responsibly sourced” 1 2 3 4 Sources: Kpler, ICE via Marketview. Notes: (1) Gunvor Singapore Pte Ltd., Vitol Inc. and Shell NA LNG LLC. (2) Estimated revenue from the agreements is based on the JKM price (as quoted by S&P Platts) and the TTF price (as quoted on www.theice.com) as of June 30, 2021 for the full term of the agreements; actual prices will vary.

Structural factors driving LNG demand Source: Platts and ICE via MarketView, SIA, IEA Electricity Market Report 2020, Kpler. 20 Region YTD growth Comments China +24% Improved gas infrastructure penetration increases demand. Increased industrial demand from economic recovery & heating demand from consumers. India (6.7)% Government policy to support natural gas to tackle pollution issues and energy poverty; vision for 15% of total primary energy consumption to come from natural gas by 2030, up from just 6.5% now. Europe (20)% Increased reliance on imported gas due to domestic declines. Higher carbon prices and climate action urgency boost demand. SE Asia 14% Fastest growing region for power demand at 5.4% in 2021. Limited private-sector financing for new coal projects makes LNG attractive as a baseload fuel.
