6-month report

30.10.2007

Sales of the Jetter group (ISIN: DE0006264005) rose by 20 % in the 
first fiscal semester, from KEUR 16,453 to KEUR 19,692. Due to orders
that had been anticipated to the first quarter, second quarter sales 
were only KEUR 8,438 (previous year: KEUR 8,421).

EBIT for the semester was KEUR 1,357, 25 % more than the year before 
(KEUR 1,082). EBIT for the second quarter was KEUR -125 (previous 
year: KEUR 475). EBIT was burdened by once-off special effects such 
as the strong increase in finished and unfinished goods of KEUR 759 
(previous year: KEUR 8), which had an averse effect on material cost.
Tax reform further burdened quarterly earnings with once-off 
accounting losses from deferred tax assets of KEUR 249. The 
consolidated result was KEUR -144 for the quarter and KEUR 1,043 for 
the semester (previous year: KEUR 504 and KEUR 1,093).

Order intake and October sales let management expect a marked 
improvement in the third and especially the fourth quarter. The 
original guidance of double-digit growth with a 10 % EBIT target is 
therefore upheld.

The quarterly financial report will be published on 09 November 2007 
and will be available on the websites of Jetter 
(http://www.jetter.de) und Deutsche Börse 
(http://deutsche-boerse.com) from then.
