In connection with the Asset Sale, the Company was required to use the net cash proceeds from the Asset Sale to repay the outstanding principal amount and associated accrued expenses (the “Debt Payoff”) of the Company’s 10% Senior Secured Notes due 2025 (the “Senior Notes”).

Financial Statements

1. Basis of Pro Forma Presentation

The accompanying unaudited pro forma financial statements of Tellurian Inc. (the “Company”) were prepared in accordance with Article 11 of Regulation S-X and are based on the historical consolidated financial information of the Company. The consolidated financial information has been adjusted in the accompanying pro forma financial statements to give effect to the disposition of the Company’s upstream natural gas assets.

The unaudited pro forma consolidated balance sheet as of March 31, 2024 gives effect to the Asset Sale and associated Debt Payoff as if they had occurred on March 31, 2024. The Asset Sale gross proceeds do not reflect all settlement statement adjustments contemplated by the PSA.

The unaudited pro forma consolidated financial statements of operations for the years ended December 31, 2023, 2022, and 2021 and three months ended March 31, 2024 give effect to the Asset Sale and associated Debt Payoff as if they had occurred on January 1, 2021.

2. Adjustments to the Pro Forma Consolidated Balance Sheet

Explanations of the adjustments to the pro forma consolidated balance sheet are as follows:

	a.	The Asset Sale gross consideration of $260.0 million (net proceeds of $250.8 million after deducting direct financial advisor costs of $3.0 million and transferred suspense funds of approximately $6.2 million).

	b.	Divestiture of the upstream natural gas properties and certain transferred liabilities.

	c.	Estimated loss on Asset Sale.

	d.	Repayment of the Senior Notes outstanding principal of approximately $223.9 million, accrued interest of approximately $6.0 million and estimated share coupon cash shortfall of approximately $3.4 million, as well as transfer of $35.0 million to a restricted deposit account.

	e.	Transfer of $35.0 million to a restricted deposit account as required by the indenture governing the Company’s 6% Senior Secured Convertible Notes (the “Convertible Notes”), which requirement replaced the minimum liquidity requirement in the Convertible Notes indenture following the Asset Sale.

	f.	Settlement of the Senior Notes outstanding principal, accrued interest and share coupon cash shortfall.

Estimated loss on extinguishment of the Senior Notes unamortized deferred financing costs.

3. Adjustments to the Pro Forma Consolidated Statements of Operations

Explanations of the adjustments to the pro forma consolidated statements of operations are as follows:

To remove the direct historical results of operations of the Company’s upstream natural gas assets.

The loss on Asset Sale and the loss on the extinguishment of the Senior Notes are not included as pro forma adjustments in the pro forma consolidated statements of operations as they are nonrecurring items. Such amounts are only presented as adjustments to retained deficit in the pro forma consolidated balance sheet.

To reflect the elimination of the Senior Notes interest expense, the associated capitalized interest and deferred financing costs amortization expense for the three months ended March 31, 2024 and year ended December 31, 2023. The Senior Notes were issued on August 15, 2023.
