Introductory Note

On October 8, 2024 (the “Closing Date”), Tellurian Inc., a Delaware corporation (“Tellurian” or the “Company”), completed its previously announced merger pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated as of July 21, 2024, by and among the Company, Woodside Energy Holdings (NA) LLC, a Delaware limited liability company (“Parent”), and Woodside Energy (Transitory) Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”). Pursuant to the Merger Agreement, Merger Sub merged with and into Tellurian (the “Merger”), with Tellurian continuing as the surviving corporation and a wholly owned subsidiary of Parent.

On the Closing Date, the Merger was consummated. Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of Tellurian’s common stock (the “Common Stock”) outstanding immediately prior to the Effective Time (subject to certain customary exceptions specified in the Merger Agreement) was cancelled and converted automatically into the right to receive $1.00 in cash, without interest (the “Merger Consideration”), and subject to applicable taxes. Pursuant to the Merger Agreement, at the Effective Time, each share of Tellurian’s Series C Convertible Preferred Stock (the “Preferred Stock”) outstanding immediately prior to the Effective Time (subject to certain customary exceptions specified in the Merger Agreement) was cancelled and converted automatically into the right to receive $8.16489 per share in cash, without interest, and subject to applicable taxes, in accordance with the terms of the certificate of designations of the Preferred Stock.

Pursuant to the Merger Agreement, at the Effective Time, each outstanding Tellurian option to purchase Common Stock (the “Options”) was canceled and converted into the right to receive an amount in cash, without interest and subject to applicable taxes, equal to the product of (i) the amount by which the Merger Consideration exceeds the exercise price of such Option and (ii) the aggregate number of shares issuable upon the exercise of such Option. Any Option with an exercise price that is equal to or greater than the Merger Consideration was cancelled without the payment of consideration.

At the Effective Time, shares of Tellurian restricted stock, restricted stock units and tracking units were converted into the right to receive the Merger Consideration, subject in some cases to continuing vesting requirements, as set forth in the Merger Agreement.

At the Effective Time, each outstanding warrant to purchase Common Stock (a “Company Warrant”) issued under that certain Warrant to Purchase Common Stock, dated April 29, 2020, by and between the Company and an institutional investor, automatically and without any required action on the part of the holder thereof, ceased to represent a warrant exercisable for Common Stock and became a warrant exercisable solely for the Merger Consideration; provided, that if the warrant holder properly requests in accordance with the terms of the Company Warrant before the 30th day after the date of this Form 8-K, then the Company will purchase the Company Warrant from the holder of the Company Warrant by paying, in cash, to the holder of the Company Warrant, within ten (10) business days after such request, an amount equal to the Black Scholes Value (as defined in the Company Warrant) of the remaining unexercised portion of the Company Warrant as of the Effective Time.

The foregoing descriptions of the Merger Agreement are qualified in their entirety by reference to the full text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Common Stock

On the Closing Date, in connection with the consummation of the Merger, Tellurian notified NYSE American LLC (the “NYSE”) that the Merger had been consummated and requested that the trading of its Common Stock on the NYSE be suspended and that the listing of its Common Stock on the NYSE be withdrawn. In addition, Tellurian requested that NYSE file with the Securities and Exchange Commission (the “SEC”) a notification on Form 25 to report the delisting of its Common Stock from the NYSE and to deregister its Common Stock under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The Company intends to file with the SEC a Form 15 to suspend the Company’s reporting obligations under Section 13 and Section 15(d) of the Exchange Act.

8.25% Senior Notes due 2028

In connection with the consummation of the Merger, the Company notified the NYSE on October 9, 2024 of its intention to voluntarily delist from the NYSE and deregister its 8.25% Senior Notes due 2028 (CUSIP Number 87968A203) (the “Senior Notes”) by filing with the SEC a notification on Form 25 regarding the delisting of its Senior Notes from the NYSE and to deregister its Senior Notes under Section 12(b) of the Exchange Act on or about October 21, 2024. The Company expects the delisting of the Senior Notes to become effective on or about October 31, 2024. After the delisting of the Senior Notes, the Company intends to file with the SEC a Form 15 to suspend the Company’s reporting obligations under Section 13 and Section 15(d) of the Exchange Act.

The Company has instructed the trustee for the Senior Notes, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), to disseminate a Notice of Redemption (the “Redemption Notice”) to all registered holders of the Senior Notes. The Company will redeem all of the outstanding Senior Notes on November 8, 2024 (the “Redemption Date”). The redemption price for the Senior Notes is $25.75 per note, plus accrued and unpaid interest to, but excluding, the Redemption Date. Book-entry interests in the Senior Notes represented by global notes will be redeemed in accordance with the standard procedures of The Depository Trust Company.

This Current Report on Form 8-K does not constitute a notice of redemption with respect to the Senior Notes. The Company called the Senior Notes for redemption only by, and pursuant to the terms of, the Redemption Notice.
