MILAN, Aug 4 (Reuters) - U.S. investment firm Sixth

Street said on Monday it had agreed to buy 38% of Sorgenia, in a

deal that values the Italian renewable energy company at 4

billion euros ($4.6 billion).

The transaction allows Spanish infrastructure fund Asterion

Industrial Partners to exit Sorgenia's capital, while F2i,

Italy's main infrastructure fund, retains its position as the

leading shareholder in Sorgenia, with a 62% stake.

Under the agreement, F2i will transfer to Sorgenia its wind

and solar power generation assets in Italy and Spain: EF Solare,

Renovalia and Renovalia Tramontana.

Asterion, which held 27.6% of Sorgenia, first invested in

the company in 2020 supporting its efforts to build a position

as a significant player in Europe's green energy transition.

"This agreement establishes Sorgenia as one of the leading

energy infrastructure platforms in Europe," Sixth Street partner

Richard Sberlati said.

Sorgenia's renewable portfolio spans solar, wind, biomass,

and hydroelectric plants.

The company currently operates approximately 1,700 megawatt

(MW) of installed renewable capacity and is pursuing development

projects totalling an additional 5,000 MW.

Rothschild & Co advised Sixth Street, together with law firm

Cleary Gottlieb.

Lazard, Intesa Sanpaolo, Mediobanca acted as financial

advisers to F2i and Pedersoli Gattai as legal adviser. BofA

Securities, Nomura and Societe Generale each advised one of the

F2i funds involved in the transaction. ($1 = 0.8636 euros)
