Densitron International Plc released interim figures yesterday. Shares inched up 1.5 points to 49.5 pence as the company reported what it described as a plainly satisfactory period for the group. The company said its continued strategy to replace its low margin, high volume business with more profitable products during the half had contributed to the group’s improved performance. Pre-tax profits climbed 58% to 892,000 pounds, which includes an exceptional 93,000 pound restructuring charge, on revenue that slipped 4% to 23.6m. The UK-based firm, which sells waveguides and other microwave products to telecommunications companies, said the European region had been especially encouraging during the half. Although the previously successful microwave business continued to slow down, profits were up 50% and Densitron said the situation looked likely to improve before the final quarter.
