The specialist mortgage finance company will make more than 95 million shares available at £2.30 per share – valuing the flotation on 4 October at around £220m for 40% of the business.
It had originally expected to list the business at around £500m. Charter Court will receive approximately £20m of gross proceeds from the offer.
It announced that various funds managed by Old Mutual Global Investors had agreed to buy around £100m of shares at the offer price to acquire 18.2% of the group.
The initial public offer (IPO) is expected to leave the major shareholders holding 53.9% of the total share capital.
Charter Court Financial Services CEO Ian Lonergan said: “Today’s announcement reflects the high level of investor interest shown in our IPO and is a clear endorsement of Charter Court’s business, track record, strategy and prospects.
“I welcome all of our new shareholders and look forward to sharing with them the next exciting stage of our development as we seek to take advantage of the further opportunities we see in our specialist mortgage markets and drive sustainable growth and attractive risk adjusted returns.”
