Largest AIM IPO in the business support services sector over the past five years has been completed

Abril 2025 — MHA plc raised US$131 million (£98 million) through a placing and retail offer, achieving a market capitalization of approximately US$363 million (£271 million) on admission. This was the largest AIM IPO in the business support services sector over the past five years. The IPO provides a platform for continued investment in technology, talent and acquisitions, supporting the group’s ambition to become a top 10 UK professional services firm.

MHA plc is a leading professional services provider of audit and assurance, tax, accountancy and advisory services, with over 1,800 employees and 23 offices. The original firm that became MacIntyre Hudson was established in 1869 and was a founding member of the Institute of Chartered Accountants in England and Wales. MHA and its predecessor firms have since expanded across the UK, both organically and through strategic acquisitions. In particular, the past 15 years have seen a significant period of corporate activity for the group. With a culture focused on providing exceptional client service and supported by strong historical financial performance, including high recurring revenues and a track record of successful acquisitions and integration, the group has grown to become the UK’s 13th largest accountancy firm by revenue in 2024, doubling in size in the last six years.
