Unaudited revenue for the second half of financial year 2006 is expected to be not less than £7.3 million, reflecting a 22 percent increase compared to the first half of 2006 and a 46 percent increase compared to the same reporting period in the second half of 2005.

This reaffirms our company's strategy to provide value-added configurable solutions for high-growth consumer applications. ARC's leadership position in the field of media subsystems is driving a higher percentage of company revenue and licensing agreements."
