London - Reuters (LSE:RTR; Nasdaq:RTRSY), the global information group, today announced that it gained market share from its principal competitor in the £2.2 billion premium tier market in 2003. Latest figures from Reuters show that it serves 28% of this market by revenue and 34% by number of positions. This represents a gain in market share in the area where Reuters has made most progress in updating its product line, confirming the Company's efforts to strengthen its premium products and improve customer service have begun to pay off.

As predicted, Reuters saw a small loss of share in the overall end user market, which accounts for around 60% of its recurring revenue base. Share was down two percentage points to 37% by revenue and to 38% by number of positions. This loss of share was driven by the relatively weaker performance of markets in which Reuters is strongest compared with the fixed income market.

Tom Glocer, Chief Executive said, "The success of our premium offering is very encouraging. We have worked hard to improve these products and it is nice to see that customer take-up has been good."

"The drop in overall market share is not unexpected and I am confident that the strength of our new products in the mid-tier and our investment in service will be the basis for strengthening our overall position."
