AIM - LOSERS

Falanx Group Ltd, down 4.8% at 1.00 pence, 12-month range 0.81p-1.76p. The cyber security and strategic intelligence services said its performance in its most recently ended financial year was hurt by delays associated with coronavirus pandemic. Falanx said revenue totalled GBP5.2 million for the year ended March 31, down from GBP5.8 million posted the year before, due to Covid-19 delays in the first half. Despite that, Falanx said it expects to report reduced a loss at an adjusted earnings before interest, tax, depreciation and amortization level for the year due to tight cost control. Going forward, Falanx said trading for the first four months of the current financial year has been encouraging and is in line with management's expectations.

SDX Energy PLC, down 10% at 13.02 pence, 12-month range 13.02p-19.45p. Hits 12-month low as drilling at the HA-1X exploration well on the Hanut prospect at South Disouq in Egypt showed the Basal Kafr El Sheikh sand had been eroded but noted good quality sands were found at the Qawasim level, however they were not charged with gas. Chief Executive Mark Reid said: "Whilst the result of this well is disappointing, I remain positive about the remaining prospectivity in the area which has not been materially impacted."
