Wearable Opportunity: Fastest Growing Market Segment Projected Growth from 2016-2020 +400% 6% +2% +1% Source: ARM company data

Wearables: A market that is still being defined Market opportunity is incredibly diverse Consumers include dogs, cows and children Market and suppliers remain in hold mode. Is it really a devices market or will services eventually become the driver Could be fashion items which will change dynamic. Market is still very new What are the compelling use cases? What is the optimum SoC? Where is the power being consumed? What is the best software platform? Business models could be different Paying for device or service? Which devices will consumers want Fitness band, watches or??? It s all about power but. Battery life is an issue in high-end Platform footprint imposing constraints Key drivers Increasingly important role for NFC as major use case e.g. payments, ticketing, vouchers etc. Health Smartwatches continued growth Data collected could be very sensitive How do you balance security and sharing? Value of wearables data still questionable.

By 2020: explosive growth expected for IoT Expected number of IoT devices shipped in 2020 6% CAGR 2.8B Smart Mobile 58% CAGR 1.6B Smart Home 1.8B Smart City IoT 54% CAGR 0.6B Industrial New ecosystems and business models are emerging 43% CAGR 1.1B Auto. 21% CAGR Source: Gartner, 2015
