ARC International plc Trading Update

SAN JOSE, Calif., and ST. ALBANS, England, January 8, 2009 – ARC International plc (LSE: ARK), a leading provider of consumer IP to OEM and semiconductor companies globally, today issued the following trading update for the period from its last Interim Management Statement on November 10, 2008 to December 31, 2008.

Current Trading
While the company saw continued strong growth in royalty revenues in 2008, the increases were offset by lower than expected licensing revenues in the closing weeks of the year, resulting from the rescheduling by two customers of licensing decisions in response to continued deterioration of industry confidence. As a result, revenues from the full-year 2008 are expected to be in the range of £15.7 to £16.2 million ($29 to $30 million). ARC’s cash position remains strong at £12.6 million.

Update on Reorganization Plan
The reorganization plan announced on September 22, 2008 was an early recognition of the challenging macro economic environment, and was designed to increase the company’s operational efficiencies and lower costs. In order to address the dramatic decline in the Pound Sterling exchange rate, management is taking actions to further reduce costs. As a result, full-year 2009 savings are expected to be at least £2.5 million, greater than the previously disclosed amount of £2.0 million. The restructuring plan is still expected to necessitate a total charge of £3.0 million, comprising a cash cost of £1.5 million and provisions for future costs, principally relating to surplus property lease obligations of a further £1.5 million. The additional actions mentioned above will necessitate £500,000 of the restructuring charge being taken in the first quarter of 2009.

Outlook
For 2009, management continues to remain cautious due to continuing uncertainty in the economic environment and fundamental industry changes. The company will report interim and full-year results on February 25, 2009.
