21 October 1999                                                        22/99


                     REUTERS THIRD QUARTER TRADING STATEMENT

London - Total revenue for the third quarter 1999, adjusted for comparability,
rose by 3% at actual rates to (pound)764 million (US$1,261 million) compared to
(pound)742 million (US$1,224 million) in the third quarter 1998. At comparable
rates, revenue was flat. On this like for like basis, revenue for the nine
months increased by 6% at actual rates to (pound)2,280 million (US$3,762
million) and by 3% at comparable rates

On a reported basis, Group revenue of (pound)763 million was unchanged at actual
rates and down 3% at comparable rates.

The adjustment to total revenue for comparability reflects the inclusion in 1998
of Reuters Business Briefing (RBB) and TIBCO Software. RBB is now part of the
joint venture with Dow Jones which became effective on 1 July. TIBCO Software
was floated on the Nasdaq stock market in July and is now accounted for as an
associate.

The third quarter saw revenue start to show the effects of a slow-down as
clients focused on upgrading their systems and installations to be
millennium-ready. This was most noticeable in Reuters Trading Systems (RTS)
where outright system sales are being deferred. This trend is likely to be even
more marked in the fourth quarter. Reuters preparations for the Millennium
transition are proceeding according to plan.

Revenue for Reuters Information (RI) rose by 6% at actual rates to (pound)405
million (US$668 million) and by 3% at comparable rates. Weaker foreign exchange
markets and a fast pace of client consolidation during 1999 restricted revenue
growth in the period.

Reuters Trading Systems (RTS) revenue declined by 7% at actual rates to
(pound)189 million (US$312 million) and by 10% at comparable rates. Risk
Management and Financial Enterprise Systems (FES) slowed as clients deferred
systems purchases ahead of Millennium changes. Dealing 2000 revenues continued
to decline following further reductions in the number of foreign exchange
traders. Dealing 3000, shortly to be launched, should offer customers an
exciting new value proposition.

Reuters Ventures revenue grew by 7% at actual rates to (pound)41 million (US$68
million) and by 4% at comparable rates. Excluding the medical businesses
disposed of in December last year, revenue growth would have been 17% at
comparable rates. The New Media business, which is now expanding
internationally, showed strong growth. Further strategic investments were made
through the Greenhouse Fund but no disposals. Four companies in which Reuters
has made Greenhouse Fund investments have floated so far in 1999 whilst a
further two have filed for an IPO.




                                       2

Instinet grew by 9% at actual rates to (pound)129 million (US$213 million) and
by 6% at comparable rates. US revenue was flat in the third quarter, reflecting
some slowing in 1999 of Nasdaq volume growth and some attrition of price and
market share due to competition. Instinet International grew 30% showing
continued good growth, particularly in Europe. A major new US$10 million brand
campaign was launched in the second half. Instinet increased the investment in
its new fixed income product in the third quarter by a further (pound)6 million.
It also acquired Montag Popper and Partners, a German fixed income broker.

PETER JOB, Chief Executive said, "As reported at the half-year, market
conditions remain challenging in our financial services business, particularly
in foreign exchange where there is lower trading activity and consolidation in
the market. We are now also facing a definite slow-down ahead of the Millennium
as customers freeze their on-site software. We are seeing the expected level of
margin improvement at Reuters Information as well as good new orders in the US
although Asia-Pacific has yet to turn around. We are therefore seeing declining
revenue growth.

"We are putting more money behind innovation, including expansion of our
flourishing Internet information business. We continue to invest in Instinet's
future both to expand its activities and position it for the significant changes
taking place in the market. The stock market debut of TIBCO Software, with a
market capitalisation in excess of US$2 billion, exceeded our expectations. A
significant profit booked from this IPO will more than cover the profit impact
of these costs in 1999. Whilst the combination of lower revenue growth with the
costs of these investments will impact operating profit, I continue to look for
improvement in profit growth during the second half of the year."
