Criteo Announces Record First Quarter Growth in the UK

135 Per Cent Increase in Client Base and 400 Per Cent Increase in Post-click Sales Fast Tracks Criteo's Q1 Momentum

LONDON, April 19, 2011 - Criteo, the global leader in pay-per-click (PPC) retargeting today
announced its UK first quarter results showing record growth for the company
including 135 per cent increase in its client base and 400 per cent rise in
post-click sales against the same period last year. Post-click sales were
also up 100 per cent compared to Q4, traditionally the strongest quarter for
e-commerce. The results are testament to the company's proven success at
driving significant incremental value for advertisers at scale.

In Q1, Criteo's impressive innovation in technology and market leadership
saw it named one of the ten biggest European start-ups by Business Insider
and shortlisted as one of the hottest and fastest growing digital media
companies in Europe by GPBullhound's Media Momentum Awards.

"Criteo's growth is a result of our continued focus on research and
development to maintain a world class platform, while investing locally in
market leading client service and campaign optimisation for our clients."
Michael Steckler, MD for Northern Europe, Criteo.

The company continues to expand globally, announcing two major industry
partnerships earlier this year which cement its position as the market leader
in personalised retargeting. In support of its ethos to offer advertisers the
highest efficiency in performance marketing, Criteo partnered with Marin
Software, the leading platform for online advertising management, to provide
a best in class complete workflow analysis and optimisation solution for
ecommerce advertisers. The partnership enables marketers to accurately
measure, attribute value and optimise performance across their search,
social, and retargeting channels within a single platform.

In March this year, Microsoft Advertising selected Criteo as Preferred
Partner for Personalised Retargeting across Europe. The partnership enables
Microsoft Advertising to implement Criteo's retargeting solution on its
European premium display advertising network Microsoft Media Network which
reaches up to 144 million European users a month. The selection was a result
of an extensive industry evaluation by Microsoft Advertising based on key
technology and industry criteria, including: value proposition to
advertisers; quality and growth of clientele; creative capabilities; volume
of impressions at competitive CPMs; and emphasis on consumer privacy and
publisher data protection.

In Q1 2011, Criteo built upon its unparalleled global reach by expanding
operations to 20 countries throughout Asia, Australia, Europe and the
Americas, and by reinforcing its worldwide leadership with the hire of
seasoned industry veterans. Greg Coleman, former Huffington Post President
and Yahoo! sales executive, joined Criteo as president to oversee global
business strategy. Max Ueno, former President and CEO of both DoubleClick
Japan and Become Japan, also recently joined Criteo as managing director of
the Asia-Pacific region.

The company currently employs more than 300 employees globally, with more
than one third dedicated to R&D. This past quarter, Criteo continued its
investment in technology, recruiting more than 100 new engineers for its
dedicated R&D centre.
