MILAN, May 30 (Reuters) - Cable maker Prysmian

will look to organic growth as well as acquisitions to expand,

its chief executive said on Thursday, as it looks to complete a

$4.2-billion deal announced last month.

"We are working on organic growth and also on M&A and a big

one is going to materialise in the U.S.", CEO Massimo Battaini

said during an online event regarding its acquisition of Encore

Wire ( WIRE ).

The U.S. competition watchdog on Wednesday gave its green

light to that deal. Encore has called a shareholder meeting on

June 26 to give final approval to the transaction.

Prysmian expects the acquisition to complete in the second

half of the year.
