MESSAGE FROM THE PRESIDENT

Beyond Connectivity

So-net has, over its 20 years as an Internet service provider,

consistently offered high-quality telecommunications

services. So-net boasts a strong track record of delivering

new value in the field of FTTH (“fiber to the home”), with the

launch of “So-net Hikari Collaboration” and the ultra-fast

“NURO Hikari.” It also provides services that cater to the

diverse consumer needs in the mobile market.

We at So-net will work to further bolster our strengths that

we have cultivated over many years, both in terms of our

know-how when it comes to developing services and

solutions and in network infrastructure technology. Moving

forward, So-net will set its sights on expanding the scope of

its business, primarily around the pillars of cloud solutions,

services, and the “Internet of Things” (IoT). In these fields,

the Company will strive to develop new businesses and to

plan and manage service-based businesses, in order to secure

further growth.

In its quest to venture “beyond connectivity,” So-net will

endeavor to work more closely with other elements within the

Sony Group, opening new doors and possibilities while

continuing to leverage the expertise it has cultivated through

its established telecommunications business. Amid growing

market interest in all things IoT, we will continue to challenge

ourselves in creating and delivering new value to our customers.

I hope that you will expect great things from So-net, as we

aim ever higher.
