21 July 2024

Dear Tellurian colleagues,

I have some significant news to share with you this afternoon. We have just announced that the Board has recommended approval of an acquisition of Tellurian by Woodside Energy.

You can read more about this in the attached press release and shareholder letter, which explains the Board’s rationale for making this decision and why this is the best path forward for our company. However, I felt it was important to reach out to you directly as I know you will have questions about how this impacts your life and career.

While we have announced the Board’s recommendation, completing a deal of this nature takes considerable time. We anticipate closing the transaction by the end of the year.

As part of our agreement, Woodside has provided Tellurian with a bridge loan to fund ongoing operations through the closing. As a result, we are not planning any employee lay-offs. Additionally, based on our discussions with Woodside, we expect many of you will be asked to work with them during a post-closing, transition period and could be offered long-term employment.

Regarding questions you might have about compensation, we can share the following:

There will be changes, both large and small, and new faces in our offices in the coming weeks and months. Much is still to be determined, but we are committed to being transparent with everyone and sharing information as it becomes available.

To that end, on Tuesday morning at 9:00 am CT, Daniel, Samik, and I will host a Town Hall for all employees in the Petroleum Club. In addition to our senior management, we will also be welcoming Daniel Kalms, Executive Vice President, from Woodside.

I want to reiterate a message I shared in our last Town Hall. Thank you. Thank you for your dedication and contributions to Tellurian. Thank you for coming to work every day and advancing our mission in the face of substantial uncertainty and challenges. You are the reason Tellurian has persevered, and you will be essential in making sure this transaction is finalized.

It has been and continues to be an honor to work alongside each of you. I look forward to seeing you in the office in the coming weeks and months. In the meantime, feel free to reach out to me directly if you have any concerns.

With thanks,

Martin Houston

Executive Chairman
