The float will also include sales shares sold by existing shareholders at the firm, including executive directors.
The company plans to free float in excess of 50% of its issued share capital, and is predicted to be eligible for inclusion in FTSE indices.
Set to be named Seraphine Group plc upon completion of the listing, the group confirmed last week that it intends to float in July 2021.
Some £16m of the funds raised will be used to repay existing loans, as well as costs picked up through the IPO.
However, the further £45m will be set aside to repay loans to a number of existing shareholders.
David Williams, CEO at the maternity retailer, said: “We strongly feel that now is the right time for the business to float.
“Listing will give us the opportunity to further the group’s reach, and continue to grow our presence and product offer in the highly resilient and under-competed maternity and nursing wear market.”
As a part of the listing, Sarah Highfield, COO and CFO at Elive, is set to join the group as a non-executive director, chairing the group’s audit committee.
