Scientific Digital Imaging plc provided earnings guidance for the year ended 30 April 2018. The Group now expects full year revenues, adjusted and reported profit before tax to be moderately ahead of previous expectations. In addition, adjusted and reported profit after tax is expected to benefit from a reduced Group tax charge which includes increased R&D tax credits accrued for both financial year 2018 and financial year 2017. The Group expects to report significant revenue growth against financial year 2017. Group gross margin is expected to be ahead of financial year 2017 mainly due to the inclusion of a one-off retrospective Licensing payment for the sale of Auto-Montage imaging software in Synoptics' first half of financial year 2018 sales, as previously disclosed in the interim results.
