Adds European Logistics Community and Transportation Management
        Capabilities to Descartes' Logistics Technology Platform




WATERLOO, Ontario, June 4, 2012 (GLOBE NEWSWIRE) -- Descartes Systems
Group (TSX:DSG) (Nasdaq:DSGX), the global leader in uniting
logistics-intensive businesses in commerce, acquired Infodis B.V., a
leading Netherlands-based provider of software-as-a-service (SaaS)
transportation management solutions.

Infodis provides a rich, functional transportation management
network-based solution that handles specific European logistics
requirements. The solution manages both inbound and outbound purchased
transportation for more than 5 million shipments per year to and from
Europe, with particular strength in Europe/Asia Pacific shipping.

"Logistics is a global business where local considerations play a key
role in the efficiency of logistics operations," said Edward Ryan,
Chief Commercial Officer at Descartes. "By combining with Infodis we
not only add critical European domain expertise and functionality to
our existing Transportation Management suite, we also welcome many
European and Asia Pacific carriers and shippers to our logistics
community."

Through the acquisition, more than 200 carriers in Europe and Asia, and
some of the world's leading high-tech companies, will be connected to
Descartes' Logistics Technology Platform, where more than 35,000
trading partners connect and collaborate to improve logistics
operations. By making Infodis' technology available on the Logistics
Technology Platform, Descartes customers can access a broader range of
European-focused transportation management capabilities as well as new
functionality, such as CO2 emission calculations.

"Descartes continues to look to combine with market leaders that share
a similar philosophy and culture of serving customers," said Arthur
Mesher, Descartes' Chairman and CEO. "Infodis, like Descartes, has been
successful in working with global category-leaders by focusing on
delivering customer results. We look forward to helping our collective
customers improve the productivity, performance and security of their
logistics operations."

Infodis is headquartered in Woerden, the Netherlands, and provides
international transportation management solutions to some of the
world's leading high-tech companies, including Philips, Sony, and
Canon. The all cash purchase price for the acquisition was EUR 3.0
million (approximately USD $3.7 million at June 4, 2012), with
Descartes acquiring approximately EUR 0.4 million in working capital
(approximately USD $0.5 million at June 4, 2012).
