Macro 4 Plc, the Crawley, UK-based systems software house saw its year end results heading in the wrong direction again, but chairman Terry Kelly is blaming the slide on internal investment and the inevitable strength of Sterling. Pre-tax profits for the year to June 30 were down 15.2% at 10.3m pounds on revenue that fell 7.4% to 23.5m pounds, but all of the group companies remained profitable and cash generative said Kelly. Macro 4 is expanding its efforts in its new Unix/NT business and has yet to see any return on this investment. The board is proposing a final dividend of 15.5 pence, bringing the total to 25.2 pence up 3.7% on last year.
