Barclays and UBS Group are the bookrunners for the initial public offering, Calcalist said, citing a person familiar with the matter. ECI has contracted a British law firm to prepare the prospectus, it added.

ECI's owner, Israeli businessman Shaul Shani, intends to list the company this year or in early 2019, the report said, noting that the telecommunications equipment supplier prefers to go public in London as most of its sales are from Europe, Africa and East Asia.

ECI Telecom said it does not comment on rumours.

A spokesman for Barclays declined to comment. Officials at UBS had no immediate comment.

Calcalist estimated the company's revenues at $380 million for 2017.
