(Recasts throughout with company statement)

Oct 13 (Reuters) - Private equity firm Warburg Pincus

plans to buy German software firm PSI Software for

more than 700 million euros ($813.26 million), the companies

said on Monday.

Reuters first reported on both a nearing takeover of PSI on

Friday and Warburg Pincus' offer for the software company on

Sunday.

PSI's software helps run power and gas transmission

grids as well as factories. It is recovering from a cyberattack

last year and on Friday it confirmed that it was in talks to

sell itself following the Reuters report.

Its stock jumped nearly 11% on Friday after the news

broke and closed at 33.2 euros a share.

Warburg Pincus' deal will value PSI at 45 euros a share,

a premium of about 50% from the software company's closing price

on Thursday.

PSI said its board supports Warburg Pincus' offer and

intends to recommend it to its shareholders. PSI plans to delist

from the German stock exchange after the closing of the deal.

PSI added that Warburg Pincus would maintain the

company's management structure and its headquarters in Berlin.

Warburg Pincus has signed agreements for about 28.5% of

PSI's equity with its anchor shareholders, PSI said. The

statement said that an unnamed anchor shareholder will partially

reinvest its proceeds alongside Warburg Pincus into PSI's

holding structure.

German businessman and newsletter publisher Norman

Rentrop is PSI's largest shareholder with a 23% stake, while

German utility E.ON is its second-largest investor

with around 18%.

E.ON will retain its stake in PSI and continue to

support PSI as a strategic investor, Warburg and PSI said.

Last year, PSI posted a loss before interest and taxes

of 15.2 million euros ($17.62 million) as it was hobbled for

weeks by the cyberattack.

Goldman Sachs is running the sale process.
