AIM - LOSERS

----------

SDI Group PLC, down 14% at 151.20p, 12-month range 137.00p-204.00p. The Cambridge-based medical technology predicts revenue of GBP69 million for the financial year that ended on April 30, up from GBP49.7 million the year before. Adjusted pretax profit is expected to be unchanged on-year at GBP11.8 million. "FY23 continued the pattern seen over recent years, with the after-effects of Brexit, Covid and a war in Ukraine creating uncertainty and generating supply chain and recruitment difficulties alongside unwelcome inflationary cost pressures," SDI says.

PetroNeft Resources PLC, down 10% at 0.20p, 12-month range 0.20p-1.30p. The oil and gas exploration company says it has so far been unable to find an auditor for its 2022 results. PetroNeft says it is becoming "increasingly clear" it will be unable to report annual results by its June 30 deadline. On Wednesday, it reported that Stimul-T LCC, the operator of Licence 61, has filed for bankruptcy administration in Russia. WorldAce owns 100% of the voting equity in Stimul-T, which owns and operates Licence 61 in Tomsk in Russia. Petroneft and its joint venture partner, Oil India International BV, are the only shareholders in WorldAce. The Stimul-T woes "clearly represents additional challenges" to the firm, PetroNeft says.
