Mobile Tornado Group PLC, down 43% at 0.80p, 12-month range 0.46p-1.92p. The provider of workforce management solutions proposes exiting the AIM market. It believes the listing on London's junior market has too much cost and "regulatory burden", and there is "limited liquidity" in trading of its shares. Moving away from AIM will offer the firm "corporate and strategic flexibility" and make it easier to access finance, Mobile Tornado claims. It also can aid a future sale process. Shareholders will have access to a matched bargain facility provided by JP Jenkins. Shareholders will vote on the delisting on September 1, and the final day of dealings will be a week later if an AIM exit is approved.
