Founded in 1991 the company has focussed all the way on house network equipment and the related technical expertise. In the Belgian market DINH Telecom is a well-known and respected brand and the company operation is based on strong technical expertise and local customer relations. The main operations of DINH Telecom such as design are located in the Belgian city of Liege. Manufacturing has been, for the most part, outsourced in Asia. The founder and principal owner of DINH, Mr. Dinh-Debouny, will continue as Managing Director of the company. The acquisition strengthens Teleste's presence in the Belgian cable network market. For Teleste Belgium is one of the most significant market areas with 95% of all households on cable. Net sales of DINH-Telecom for 2006 amounted to approximately EUR 8 million with good business profitability. The effect on Teleste's net sales in the second half of 2007 is estimated round EUR 6 million. The deal boosts Teleste's profitability for the current year while having no essential effect on Teleste's equity ratio or gearing. The acquisition increases the number of Teleste personnel by 20. The consolidated equity of the acquired companies at the time of the deal equals about EUR 4.4 million with the balance sheet total amounting to approximately EUR 5.8 million. The minimum contract price for the capital stock stands at EUR 6 million. This price may increase depending on the development of the net profit of the acquired company in the next two years. Part of the contract price is covered with Teleste's own shares. The objective is to develop network services provided for the operators locally through the acquired company and incorporate these in Teleste's service strategy. For this the key expertise and strong market presence of DINH-Telecom create favourable conditions. Moreover, Teleste aims at expanding and strengthening its product range particularly by including active components of house networks while consolidating its design know-how in the field. Along with Belgium the involved products will also be made available in Teleste's other main markets.
