RSM Tenon Group has posted revenues down 8.8% to £208m after a "really tough" year which saw 400 staff made redundant.
Its results for the year ended 30 June said underlying business remained "resilient in a challenging market".
It suffered an underlying operating loss of £8.9m, compared to a 2011 underlying operating profit of £18.5m.
The business said it had made significant changes during the year, including board and management changes, cost reductions and non-core disposals. It made annual cost savings of £20m.
It also said its bankers, Lloyds Banking Group, had committed £93m to the business over the next two years.
Chairman Tim Ingram said: "To say that the year ended 30 June 2012 was a disappointment would be an understatement; this year has been totally unsatisfactory for shareholders and other stakeholders.
"The results speak for themselves… It was unacceptable to have allowed a situation where costs had grown to be in excess of revenues, and bank indebtedness had become a multiple of the company's market capitalisation.
"Although the external economic environment has not been helpful, the main reason for this state of affairs is that the business had in the past simply not been managed in the way it should have been.
"Of critical importance are the changes that have been, and are being, made to enable the business to provide the profitable returns that it should - and can - provide for shareholders."
