Exhibit 99.1

Talos Energy Inc. Announces $100 Million Share Repurchase Authorization

HOUSTON, Texas, March 20, 2023 – Talos Energy Inc. (“Talos” or the “Company”) (NYSE: TALO) announced today that its Board of Directors approved a $100 million share repurchase program of the Company’s common stock. This approval grants Talos’s management the authority to repurchase shares opportunistically in the open market from time to time, in privately negotiated transactions, or by such other means as will comply with applicable state and federal securities laws. This is the Company’s first authorization for share repurchases since its founding.

Talos President and Chief Executive Officer Timothy S. Duncan commented: “We believe our stock has traded at a significant discount to our fundamental value for some time. At current trading levels, that discount creates a buying opportunity too compelling to pass up and has led to the decision to revise our capital allocation framework and approve a substantial share repurchase authorization. We remain excited about the catalysts in the stock and the outlook for our business. Accelerating our repurchase program provides an additional impactful opportunity for our shareholders.”

The timing of any repurchases under the share repurchase program will depend on market conditions, contractual limitations and other considerations. The program may be extended, modified, suspended or discontinued at any time, and does not obligate the Company to repurchase any dollar amount or number of shares.
