Dec 17 (Reuters) - Talos Energy ( TALO ) said on Tuesday

it would terminate its so-called poison pill after it reached an

agreement with Mexican billionaire Carlos Slim's investment firm

that it would not exceed a threshold of 25% ownership in the oil

and gas firm.

In October, the company had adopted the shareholders rights

plan after Slim's Control Empresarial De Capitales accumulated

24% of Talos' common stock.

Poison pill, or shareholders rights plan, is often used by

corporates to thwart hostile takeover bids.

Talos said on Tuesday it has entered into an agreement with

Slim's firm that through Dec. 16, 2025 it would not acquire

additional shares of Talos common stock, which would cause the

investor group's holdings to exceed 25%.

Separately, Houston, Texas-based Talos said it would sell an

additional 30.1% interest in its Mexico unit to Zamajal - owned

90% by Grupo Carso and 10% by Control Empresarial, both of which

are backed by Carlos Slim.

Last year, the unit of Grupo Carso had purchased a 49.9%

stake in Talos Mexico.

After the deal closes, Talos Energy ( TALO ) will own 20% in Talos

Mexico, while the rest will be held by Zamajal.

Talos Energy ( TALO ) will receive $49.7 million in cash, with an

additional $33 million due upon first commercial production from

the Zama Field.

The Mexican subsidiary of Talos Energy ( TALO ), which discovered the

Zama Field in 2017, controls 17.4% of the potentially lucrative

deposit in Mexican territorial waters in the Gulf of Mexico.
