Board and role changes

ARM Holdings plc ("the Company") announces that Mike Inglis has given the Company advanced notice that he wishes to step down from the board and leave the Company in March 2013. He plans to take part in a round the world sailing race later in 2013.

Simon Segars will take on the new role of EVP and General Manager of the Processor and Physical IP Divisions with effect from 2 April 2012. At the same time, Mike will take on the new role of Chief Commercial Officer.

Warren East, CEO of the Company said:

"We believe that by combining the top level management of the Processor and Physical IP divisions under Simon's experienced leadership, we can continue to drive the successful collaboration between our IP divisions and exploit the growing synergies to maximum effect. Although we will miss Mike's expertise across a broad range of functions when he leaves in 2013, I am confident we will use his energy and talent to great effect over the next 12 months."
