Sunday Business racked up losses of £7.9m on sales of £4.3m and faces closure if it can not find new investment.
Scotsman Publications (Holdings) lost £1.3m against a profit of £5.8m last year after publisher Andrew Neil, a former long-time editor of the Sunday Times, relaunched The Scotsman newspaper at a cost of £5m.
This is the first loss the holding company has made since the Barclays took it over in 1995.
Scottish Publications (Holdings) also suffered a £2m loss on the launch of its internet portal scotsman.com, which trimmed costs in July with the loss of around 20 staff.
The company is also facing rising interest charges on a £58m loan, of which £48m is to be paid back next year.
The company's financial director George Affleck told Business AM that the holding company's results did not accurately reflect the financial situation of the newspapers.
However, this week the Barclays issued Sunday Business managing director Paul Woolfenden with an ultimatum to find a solution to the paper's financial situation.
Earlier this year, Express Newspapers proprietor Richard Desmond had been reported to have expressed an interest in the title.
