QSC's revenues and profitability up sharply in Q1/2006

• Revenue growth of 31 percent
• Gross profit up by 52 percent
• EBITDA rises by 85 percent
• Accelerated network expansion

Cologne, May 15, 2006. According to preliminary results, Cologne-based QSC AG grew its revenues by 31 percent in the first quarter of 2006 to € 54.4 million, as opposed to € 41.5 million for the same quarter the year before. All four of the company's business segments contributed to this strong growth.

According to preliminary results, gross profit rose by 52 percent to € 16.4 million, as opposed to € 10.8 million for the same quarter the year before; the resulting gross margin improved to 30 percent, as opposed to 26 percent for the first quarter of 2005. The company's preliminary EBITDA rose by 85 percent to € 2.4 million, as opposed to € 1.3 million for the first three months of 2005. There was an even stronger improvement in QSC's net result, which according to preliminary results totaled € -3.0 million net loss, as opposed to € -5.1 million net loss for the first quarter of 2005.

Prompted by demand on the part of enterprise customers and wholesale partners, QSC connected 13 further cities to its DSL network during the first quarter of 2006 and invested accordingly in those areas. Working in close coordination with its wholesale partners, the company also continued to upgrade its network with ADSL2+ technology. Consequently, capital expenditures rose to € 7.3 million, as opposed to € 3.8 million in the first quarter of 2005. These capital expenditures, as well as the annual pre-payments for services and products from Deutsche Telekom for the full fiscal year that are due and payable during the first quarter of each year, resulted in a net cash burn. The company's liquid assets totaled € 42.9 million as of March 31, 2006.
Given the encouraging development of its operating business during the first quarter of 2006, QSC is reiterating its forecast for the full fiscal year: The company anticipates revenues of over € 240 million and an EBITDA of between € 15 and 20 million. QSC plans to cross the net income profitability threshold by year-end.
