Outlook
We reiterate our previous guidance for 2009; that we expect group
dollar revenues for the full-year to be at least in line with market
expectations, unless industry conditions deteriorate to a greater
extent than is generally anticipated. 

Overall semiconductor industry activity continued to slow in Q1 2009,
and whilst there are early signs of improving visibility in some
sectors, the near term remains uncertain. However, with demand for
ARM's portfolio of products remaining robust, we believe that the
Company is positioned to continue to perform resiliently in this
difficult trading environment. 


Warren East, Chief Executive Officer, said:"ARM has made an encouraging start to 2009. Leading semiconductor and
OEM companies are continuing to utilise ARM technology, creating
healthy demand for our latest processors and physical IP products.

ARM has outperformed the semiconductor industry in the first quarter.
ARM's Q1 dollar revenues are 10% lower than a year ago whilst overall
industry revenues have declined by about 30% over the same period(1).
This outperformance, combined with careful management of
costs and the strengthening of the dollar against sterling, has given
rise to year-on-year earnings growth of 18% and further robust net cash
generation in the first quarter."
