Current trading and the expected normalised operating expenses for the quarter are consistent with the outlook commentary included in our Q2 earnings announcement on 22 July 2015.

During the analyst and investor day, ARM will present the company's investment strategy, with particular focus on:

· Mobile Computing: ARM expects to continue to invest in future technologies for smart mobile devices;

· Enterprise Infrastructure: ARM is increasing its investment in technologies for networking infrastructure and servers in order to achieve a higher market share than previously forecast;

· Internet of Things: ARM is investing in complementary technologies that are expected to generate new revenue streams from emerging opportunities.

The investments announced today will result in additional revenues and operating costs. During the presentations, management will outline the expected scope of the investments, and the likely returns.

This phase of new investments is expected to be EPS accretive from 2017 onwards. The normalised operating expenses associated with this additional investment are mainly related to the hiring of more R&D engineers and technical marketing staff. These expenses will ramp through 2016, and are expected to grow to approximately £40 million (GBP) for full-year 2017, after which these expenses will grow more modestly. This investment is expected to add about $40 million (USD) of revenues in 2016, rising to approximately $200 million (USD) in 2020.

More details will be given during today's presentations.
