Background to and reasons for the Acquisition Sumotext is an established and leading provider of messaging solutions in the US, based in Little Rock, Arkansas. The Acquisition enhances IMImobile’s position in the US market and consolidates its footprint within the region. The US market is competitive, and the experienced team at Sumotext will provide valuable expertise as well as an established customer base made up of a government agency, travel companies, retailers, healthcare companies and other leading brands, agencies and non-profit organisations. A key attraction of the Acquisition for IMImobile was the experience and skills of the founder of Sumotext, Tim Miller, who has agreed to join the Group as a member of the senior management team, and will maintain leadership of the Sumotext business. The Acquisition is complementary to IMImobile’s product set, providing mobile solutions that enable businesses to manage digital interactions with their customers. As a result of the Acquisition we see many opportunities for growth in the US region and we will work to use the Sumotext business to penetrate the enterprise market, and expect it to be earnings enhancing during the year to 31 March 2019. Trading update The Board is pleased to provide the following trading update ahead of the Company’s interim results announcement on 21 November 2017. The first half of the year has seen trading in line with management expectations, with good overall organic gross profit growth. The Board remains confident about the Group’s prospects for the remainder of the year and expect underlying revenue and gross profit to be ahead of expectations. We see many opportunities for further growth, particularly in the enterprise market in the US and UK. Following the Acquisition, in order to capitalise on product leadership and market opportunities, IMImobile intends to increase sales and marketing expenses in the second half of the current financial year by approximately £0.5m, the benefits of which we expect to be realised in the financial year ending 31 March 2019. Prior to this planned investment underlying EBITDA for the full year was expected to be in line with expectations.
