Share trading in Clarkson Hill has been temporarily suspended after the national IFA failed to submit its annual accounts.
Under AIM rules, failure to publish by 1 July means an automatic suspension.
However, the London Stock Exchange says the ban will be lifted in due course, once the group publishes its annual accounts and has posted them to shareholders.
Clarkson Hill Group retains the services of 340 advisers and operates out of 10 branches including in London, Edinburgh, Newcastle and Leeds. The HQ is in Cambridgeshire.
