Immunodiagnostic Systems Holdings has warned that revenues for the year to March are likely to be lower than current market forecasts.

It said revenues for the nine months to December were £39.6m, compared to £35.4m for the comparable period in 2010 but as a consequence of the trading pattern now being experienced, it expects revenue for the full year to be between £52m and £53m, lower than current market expectations.

Operating costs for the year are expected to be in line with previous estimates but given the reduced revenue expectations pre-tax profit on a pre-exceptional basis is now forecasted to be between £14.5m and £15.3m.

IDS says its operations remain highly cash generative with net cash of £3.6m at the end of December compared to net debt of £2.3m at December 2010
