GREIFENSEE, Switzerland and COLUMBUS, Ohio, USA - July 27, 2006 -
Mettler-Toledo International Inc. (NYSE: MTD) today announced net earnings
of $34.8 million, or $0.84 per share on a diluted basis, for the quarter
ended June 30, 2006. The second quarter 2006 results include $0.04 per
diluted share of share-based compensation expense. In the second quarter of
2005, net earnings per diluted share were $0.42, which included a one-time
$0.30 per share charge for the previously disclosed pipette litigation. The
second quarter 2005 results did not include any share-based compensation
expense. Excluding the effects of share-based compensation expense and the
one-time pipette litigation charge, net earnings per diluted share would
have increased 22% in the second quarter.

Sales for the quarter were $389.2 million, compared with $368.6 million in
the prior year, an increase of 5% in local currency sales. Reported sales
growth in the quarter was 6%, which includes a 1% favorable currency
benefit. By region, local currency sales growth for the quarter was 4% in
Europe, 7% in the Americas and 4% in Asia / Rest of World. In the quarter,
adjusted operating income amounted to $56.4 million, a 10% increase over
the prior year amount of $51.4 million.

Sales for the six-month period were $735.3 million, compared with $705.8
million in the prior year. This represents a 4% increase in reported sales,
consisting of 6% local currency sales growth and 2% unfavorable currency
impact. For the six-month period, net earnings per diluted share were $1.41
in 2006, which included $0.07 of share-based compensation. Net earnings per
share on a diluted basis in the comparable 2005 period were $0.89 and
included the above-mentioned $0.30 per share charge. Net earnings in 2005
did not include share-based compensation. Excluding the effects of
share-based compensation and the one-time pipette litigation charge, net
earnings per share would have increased 24% over the prior year period.
Adjusted operating income for the six-month period was $96.8 million in
2006, an 11% increase over the prior year amount of $87.1 million.

Cash flow from operations in the second quarter was $53.1 million, compared
with $50.6 million in the prior year quarter. Cash flow from operations in
the six month period was $72.2 million, compared with $57.3 million in the
prior year. The Company repurchased 0.8 million shares of its stock for
$49.2 million in the quarter and 1.9 million shares for $117.2 million
during the first six months of 2006.

Robert F. Spoerry, Chairman, President and Chief Executive Officer, stated,
"We are very pleased with our second quarter performance. We experienced
growth across all business areas. We had another quarter of year-over-year
improvement in gross margins, which helped to drive another quarter of
solid operating profit growth. Our EPS growth, adjusting for one-time
items, was very strong. Finally, our cash flow generation continues to be
solid."

The Company announced that the Board of Directors has authorized a $400
million increase to the share repurchase program through December 2008. The
Company currently has a $500 million stock repurchase program through the
end of 2007 of which $114 million is available as of June 30, 2006. Spoerry
commented, "The expanded share repurchase program reflects the confidence
we have in the organic growth potential of our business. Our balance sheet
and cash flow generation are very strong, and we believe the program will
continue to enhance shareholder value." The Company added that repurchases
will be made through open market transactions, and the timing will depend
on business and market conditions, stock price, trading restrictions, the
level of acquisition activity and other factors.

Spoerry concluded, "We had a strong first half in 2006 and are well
positioned to reach our targets for this year and to continue to grow our
business in the coming years. We have revised upward our full year EPS
targets to reflect our strong performance to date and our continued
positive outlook for the remainder of the year. Based on an economy and
market conditions similar to today's, we remain confident in our ability to
achieve these revised targets."

The Company stated that based on an economic environment and market
conditions similar to today's, it now expects 2006 EPS, including
share-based compensation expense, to be in the range of $3.26 to $3.31
compared with previous guidance of $3.22 to $3.27. EPS guidance, excluding
the impact of share-based compensation expense, is $3.40 to $3.45, compared
with previous guidance of $3.36 to $3.41. This guidance is based on local
currency sales growth in the range of 4% to 6%, which remains unchanged.
The Company added that it expects third quarter 2006 EPS, including the
impact of share-based compensation, to be $0.79 to $0.81 and, excluding
share-based compensation, to be $0.82 to $0.84.

The Company has provided a reconciliation of adjusted operating income to
earnings before taxes, the most comparable U.S. GAAP measure, in the
attached schedules.
