LandMark White's auditors have cast doubt about the valuation firm's ability to keep trading despite the recent capital raising and directors' assurances of a return to profitability by the end of this calendar year.

The ASX-listed valuer published its annual report on Tuesday, confirming the full-year after-tax loss of $15.1 million that it reported last month and repeating the directors' statement that they expected LandMark White's revenue and profitability to have returned to a level permitting "appropriate" returns to shareholders by year-end.
