U.S. energy firm AES Corp. (AES.N) is in talks to sell its majority stake in one of Vietnam's largest coal-fired power plants, two people familiar with the discussions said, as part of its global strategy to divest coal assets by the end of 2025. AES is discussing the sale with Sev.En Global Investments A.S., the financial vehicle for foreign acquisitions of Czech energy firm Sev.en Group, ultimately owned by billionaire Pavel Tykac, the two people told Reuters, declining to be named because no deal had been finalised yet.

It was not clear if AES was in talks with other potential buyers. The plant's second-largest shareholder, South Korea's energy firm Posco International Corporation (KOSE:A047050), told Reuters it was also considering selling its 30% stake, but did not elaborate further. AES had no immediate comment.

Sev.en declined to comment. AES had tried to sell its 51% stake in the 1.2 gigawatt Mong Duong 2 coal-fired power plant in 2021 but the deal fell through after the company said it signed a sale agreement with a consortium led by an undisclosed "U.S.-based investor". The sources did not say how much AES's stake could be valued at under the current deal being considered.

Posco's 30% stake was valued at $185 million when it had tried to sell in 2021, according to a regulatory filing from the company. That deal, which collapsed like the AES one did, would have valued the plant at over $600 million. Sovereign wealth fund China Investment Corporation (CIC), which owns the remaining 19% stake in the plant, is considering selling under the terms agreed by AES with potential buyers, one of the sources said.

It is unclear whether CIC was also considering a potential sale to a possible buyer of Posco's stake. CIC did not reply to a request for comment.
