AIM - LOSERS

----------

Tribal Group PLC, down 12% at 43.85 pence, 12-month range 37.00p - 96.00p. The Bristol-based educational software and services provider reports that Singapore's Nanyang Technological University has decided to terminate its contract with the company and has also reserved rights to claim damages. Tribal says it rejects NTU's right to terminate and is considering its options regarding the next appropriate steps. Consequently, the company revises the publication date of its annual results to March 24 to allow it time to consider the impact of the contract termination, particularly the accounting treatment of a GBP4.5 million onerous contract provision contained within previous expectations. Tribal has an eight-year contract with NTU for the delivery of Tribal's cloud-based SITS:Vision Student Management System and its Tribal Edge solutions. The contract was originally announced back in April 2021. In February, the company said significant delays in its Singapore contract hurt its overall trading in 2022.

----------

Jubilee Metals Group PLC, down 5.8% at 7.45 pence, 12-month range 7.30p - 17.50p. The London-based metal processing company says interim profit more than halved as the metal processing company grappled with power outages in South Africa and poor infrastructure in Zambia. Reports a 54% decline in pretax profit to GBP4.3 million for the six months that ended December 31 from GBP9.3 million a year earlier. Revenue dips to GBP63.1 million from GBP63.3 million. Platinum group metals operations record 18,208 ounces, all from own operations, down from 20,316 ounces. Records copper production of 1,149 tonnes compared to 1,314 tonnes and below expectation as a consequence of the delayed ramp-up of the Roan concentrator, mainly due to power and water disruptions in Zambia.
