REUTERS GROUP PLC — INTERIM RESULTS (UNAUDITED) 27 July 2007
for the six months ended 30 June 2007...

Tom Glocer, Reuters Chief Executive, said: “Against the backdrop of the pending Thomson-Reuters transaction, Reuters stayed focused on driving growth in the first half and delivered the strongest six months of sales and installations in more than five years. We are off to a very good start in planning for our integration with Thomson. The more we advance in these activities, the more excited I become about the prospect of creating a truly great information company.”...

PROGRESS UPDATE ON THE THOMSON-REUTERS TRANSACTION
Since the announcement of the Thomson—Reuters transaction on 15 May, there has been progress in the following areas:

• Positive feedback from customers

• Integration planning workstreams identified: top team selected

• Initial discussions with the Canadian Competition Bureau with filing expected to follow soon

• Commitment to maintain a strong operating presence in both London and New York...

3) Thomson deal-related costs

During 2007, Reuters has incurred certain charges in relation to the Thomson deal announced on 15 May. These include third party advisor and legal fees.

As the Thomson-Reuters combination will not be accounted for as an acquisition in Reuters financial statements, deal-related costs incurred by Reuters are required to be expensed. This treatment is dissimilar to transaction-related costs previously incurred by Reuters, which were either capitalised as a cost of acquisition or charged to profits on disposal (which were recognised outside of Reuters trading profit, adjusted earnings and related cash flow and margin measures).

Given their once-off nature and dissimilarity to previous transaction-related costs, Thomson deal-related costs have therefore been excluded from certain profit, cash flow and margin measures to enable better like-for-like comparisons between periods...
