AIM-listed Elektron Technology swung to a loss in the first half after two factory relocations caused production delays and one-off costs to fix the situation. More than £2m of sales orders that were due for delivery in the first half had to be deferred to the second half knocking operating profit and cash generation to the tune of £1m. An additional £1m of costs have been incurred to support prodouction and resolve the sales backlog.Chief Executive John Wison said: "This has been a very challenging period for us. However the operational issues we experienced have been addressed and we are already seeing improvements in performance and in the sales backlog."The Cambridge-based technology group reported a pre-tax loss of £2.4m in the six months to the end of July compared with a profit of £0.5m in the same period last year. The numbers included £0.9m of restructuring costs relating to the streamlining of its operations. Elektron said that while the production problems caused by the factory moves had stabilised it still expected to incur further operational recovery costs in the second half - albeit at a lower level.No dividend will be paid. Elektron's net debt pile stood at £5.8m at the end of July, up from £5m at the end of January.Shares in Elektron Technology were down 5.9% at 10p. TB
