Software company Micro Focus posted a 3.4% fall in full-year net profit, partly due to costs associated with its $1.2bn acquisition of US rival Attachmate, although the same deal helped to almost double its revenue.For the year ended 30 April 2015, pre-tax profit fell to $91.4m from $138.4m, but revenue surged 99.6% to $834.5m from $418.1m. Licensing revenue grew 52.4% to $261m from $171.3m.Micro Focus said the integration of Attachmate was ahead of plan and revenue, underlying adjusted earnings before interest, tax, depreciation and amortisation and earnings per share were ahead of market expectations.The company recommended a final dividend of 33 cents per share, up 10% on the year and taking the total dividend to 48.4 cents, up from 44 cents.Executive chairman Kevin Loosemore said: "This has been a transformational year for Micro Focus building on the platform we have been developing since 2011."
