Nextdc (ASX:NXT) opened the retail portion of its fully underwritten 1-for-5.4 accelerated non-renounceable entitlement offer to raise about AU$1.5 billion in total, according to a Monday filing with the Australian bourse.

The retail offer, expected to raise around AU$500 million, is priced at AU$12.70 apiece, the same price used in the institutional component, which recently closed and raised about AU$1 billion, per the filing.

Eligible retail shareholders who fully exercise their entitlement may also apply for additional new shares up to 100% of their entitlement at the offer price under the top-up facility, the filing added.
