Building developer McInerney has reported pre-tax losses of more than €200m for last year.
The company has been badly hit by the slump in the Irish and UK housing markets.
It took a financial hit of €82.5m due to the falling value of its land.
There were also almost €10m in restructuring costs.
The company said sales in the early months of this year continued to be slow, though it saw falling house prices and lower interest rates as having a positive impact in the medium term.
McInerney has negotiated new lending agreements with its bankers in Ireland and the UK to reflect the tougher market conditions.
However, it says talks with banks are continuing, warning that 'constant revisions' of these arrangements will be needed if it is to continue in business.
