CLX Communications AB ("CLX" or the "Company") today announces its intention to proceed with an Initial Public Offering (the "IPO") and to list its shares on Nasdaq Stockholm. CLX is a leading provider of cloud-based communication services and solutions to enterprises and mobile operators.

Nasdaq Stockholm has decided to admit the Company's shares to trading, subject to customary conditions. Depending on current market conditions, the IPO is expected to be completed during 2015.

CLX expects that the IPO can further increase awareness of the Company's business and activities, strengthen CLX's profile with investors, customers and business partners and broaden CLX's shareholder base.

Johan Hedberg, CEO and co-founder of CLX comments:

"CLX has since inception shown strong and profitable growth. The Company is a leading provider of cloud-based communication services and solutions to enterprises and mobile operators globally. Our direct reach to around 7 billion mobile subscribers and connected "Things" worldwide and the internally developed carrier-grade communications platform provide us with key competitive advantages as we continue to implement our strategy to further strengthen our position in the market. We are seeing significant opportunities ahead in our enterprise mobile messaging services via SMS (A2P SMS, Application to Person) and, further ahead, in our mobile connectivity services for the Internet of Things. The IPO will help to strengthen CLX's profile with customers, business partners and investors."

Erik Fröberg, Chairman of CLX's Board of Directors comments:

"CLX has since inception in 2008 developed into a leading global provider of cloud-based communication services to enterprises. Over the past three years the Company's revenues have doubled to SEK 844 million of which more than 90 percent are sales outside Sweden. A listing of the Company's shares is a logical step in CLX's development and will help to strengthen the Company's profile and support its continuing expansion."

Key financials

About the enterprise cloud communications market

The cloud refers to the concept of Internet-based sites and software (rather than traditional internal systems and servers), through which users can access applications. Generally, the cloud eliminates the need to install and integrate software and hardware internally, and provides a global online access point to such software. Cloud communications consist of Internet-based messaging, voice and mobile data communications that are delivered through the traditional telecommunications infrastructure (including the networks of various mobile operators).

The enterprise cloud communications market has grown as customers and employees have increasingly shifted their communications and content consumption to mobile devices. Mobile communications has provided enterprises with new opportunities to communicate with customers, employees and, most recently, connected "Things" around the world.

The enterprise cloud communications market is primarily driven by three key market drivers:

• Growing number of smartphones and increasing mobile data traffic
• Transition of business critical services to the cloud
• The development of existing and new use cases within the enterprise cloud communications market

While the mobile data market for the Internet of Things has only recently become a viable market opportunity, CLX believes that there is potential for market growth. According to several market researchers and mobile operators, the number of connected "Things" is expected to grow significantly in the coming years. CLX's connectivity service for the Internet of Things is in the advanced stages of development and the Company expects that commercial launch of its services will occur in 2016.

Offering highlights

The IPO will include an offering to the general public in Sweden and to institutional investors in Sweden and abroad. The current shareholders in the Company, including Cantaloupe AB (an entity owned by the founders of CLX) and Neqst 1 AB (through wholly owned subsidiary), intend to reduce their ownership in CLX.

Carnegie Investment Bank and Handelsbanken Capital Markets are acting as Joint Global Coordinators and Joint Bookrunners in the IPO. Advokatfirman Lindahl KB and Latham & Watkins (London) LLP are legal advisors to CLX.
