Nov 21 (Reuters) - Swiss private equity firm Partners

Group said on Friday it and its affiliates would for

now retain a majority stake in Esentia Energy Development

after its portfolio company began trading on the

Mexican stock exchange this week.

Assuming the option to purchase additional shares is not

exercised, funds affiliated with or advised by affiliates of

Partners Group will hold about 70% of Esentia's issued and

outstanding common stock, Partners Group said in a statement.

Shares of the energy company rose by as much as 10% from its

IPO price following its market debut on Thursday, which raised

more than $600 million, according to BBVA Mexico.
