The integration challenge Tiscali Q and Q EBITDA

Financials – quarterly results

Growth of access revenues (+1% Q on Q) limited by strong reduction in marketing expenditure (-66%) and by some special access offers in Germany which have now been terminated. Growth in minutes’ traffic was about 10% in the quarter Portal revenues, including advertising sales, continue to increase rapidly (+18%) even in a declining European market Reduction in low margin voice sales in line with our strategy and expectations Keeping our promises for reduction in G&A/personnel costs B to B sales are down 25% from the previous quarter due to a revenue peak in Q4 00 and in particular to the demands of the integration process in Q1 01. We expect that the growth trend will resume from Q2 Benefits of network, technology cost savings and revenue synergies estimated to come through by Q3/Q4 2001
