Under AIM rules, Prestbury was required to post its figures for the six months to June 30 by the end of September.
In a stock market statement, it said it would not be able to do so. The shares were priced at 1.75p when they were suspended, giving Prestbury a market value of £531,000. In June, the shares were suspended when it was unable to publish audited results for the 14 months to the end of 2007.
A month later, it unveiled losses of £1m on turnover of £10.78m, following which the shares suspension was lifted.
The losses followed an `intensely challenging' period in which revenues from remortgages tumbled in the wake of the Northern Rock debacle and credit crunch.
Prestbury, which is based in Alderley Edge, also provides life assurance and critical illness policies.
In July and August the company, was at the centre of controversy when rebel investors attempted to oust chief executive Lee Birkett and his finance director mum Lynne, although the bid ultimately failed.
Shareholders Armadillo Investments and Arlington Specials Situations Fund said they had lost confidence in Prestbury's corporate governance standards and believed the business was suffering too many conflicts of interest.
Mr Birkett, who co-founded Prestbury in 1994, is its largest shareholder with a stake of more than 25 per cent. He and his mother secured support from almost 60 per cent of investors to defeat the rebels.
A source said it was highly unusual for a company's shares to be suspended twice for failing to produce its results on time.
"They obviously have problems but will be trying to get the figures out as soon as possible," the source added.
Earlier this year, co-founder Steve Keenan quit as chief operating officer. Talks led by Mr Birkett aimed at taking the company private also came to nought.
