• Sales in local currency declined by 8% in the quarter. Reported sales decreased 15% due to a negative 7% currency impact.

• Net earnings per diluted share as reported (EPS) were $1.00, compared with $1.06 in the first quarter of 2008. Adjusted EPS was $0.95, a 6% decline from the prior year amount of $1.01.

A reconciliation to EPS is provided on the last page of the attached schedules.

First Quarter Results

Olivier Filliol, President and Chief Executive Officer, stated, “While the severe economic downturn has certainly impacted our local currency sales, our disciplined cost management and the benefit of pricing and procurement initiatives helped to limit the impact on our first quarter earnings. Given our expectation of continued difficult market conditions, we are taking further measures to reduce our cost base while continuing to invest in our business for the long-term benefit of shareholders. We remain confident that Mettler-Toledo will emerge from this downturn an even stronger company with an enhanced competitive position.”

EPS was $1.00, compared with the prior year amount of $1.06. Adjusted EPS was $0.95 as compared to the prior year amount of $1.01.

Sales were $374.1 million, compared with $439.0 million in the prior year, reflecting a 8% decrease in local currency sales compared with the prior year quarter. Reported sales declined 15% due to a negative 7% currency impact. By region, local currency sales decreased 10% in Europe and 11% in the Americas. In Asia / Rest of World, sales increased by 1%. Adjusted operating income amounted to $52.3 million, a 10% decrease over the prior year amount of $58.3 million. Adjusted operating income is a non-GAAP measure and a reconciliation to earnings before taxes is provided in the attached schedules.

Cash flow from operations was $34.9 million, compared with $8.2 million in 2008.

Cost Reduction Program

The Company previously announced a Cost Reduction Program with a target of reducing costs by more than $40 million annually. The Company has now expanded the Program to target total cost reductions of approximately $100 million annually. Pre-tax restructuring charges associated with the expanded Program are estimated at approximately $40 million, of which $14.8 million has been incurred to date. The remaining amount will be substantially recognized during the next several quarters. Similar to the initial phase, the expanded Program will include workforce reductions and other cost efficiency measures.

Outlook

The Company reiterated that forecasting continues to be very difficult given the significant uncertainty and volatility in today’s global economy. Management now estimates local currency sales will decline in 2009 in the range of -8% to -12% and Adjusted EPS will be in the range of $4.85 to $5.35. Adjusted EPS excludes purchased intangible amortization, discrete tax items and restructuring charges.

For the second quarter 2009, the Company noted that the second quarter 2008 had very strong local currency sales growth. The Company anticipates local currency sales will decline in the range of -11% to -13% and Adjusted EPS will be in the range of $1.05 to $1.15 for the second quarter.

While the Company has provided an outlook for Adjusted EPS, it has not provided an outlook for EPS. EPS guidance has not been provided because it would require an estimate of non-recurring items for 2009, which are not yet known.

Conclusion

Filliol concluded, “While the steps we are taking are difficult, we are committed to taking determined actions to align our cost structure to our currently reduced sales volume. At the same time, we have been diligent and careful in our planning to ensure that we reinforce our leadership position for the long term, with continued high levels of investment in research and development and Spinnaker-related enhanced marketing programs.

“Mettler-Toledo’s strong franchise is supported by our market-leading positions, global footprint, robust and diversified product portfolio, an experienced global management team, and a solid capital structure. This foundation, combined with our proven track record on execution, provides us the support and flexibility to weather the current environment.”
