Austock is expecting to list on the Australian Securities Exchange on December 17, following the release of its prospectus to ASIC.
The diversified financial services group is to offer six million shares at $1.80.
On listing, Austock will have a market capitalisation of $214.3 million.
The share offer opens on November 20 and closes on December 6.
The group, formed in 1991, employs more than 200 staff with offices in Melbourne, Sydney, Brisbane and Chicago and has affiliations in the United Kingdom and Europe.
In 1997 the group established Austchoice, the first cooperative of financial planners in Australia.
Deakin Financial Services acquired AustChoice in 2004.
In September the group's subsidiary Austock Asset Management hired former Challenger staffer Alan Sheen as its new managing director.
Sheen is responsible for over $400 million in Austock funds.
