Third Quarter Results

Olivier Filliol, President and Chief Executive Officer, stated, “We are very pleased with our strong operating results in the third quarter. Local currency sales growth was broad-based across most geographies and product lines. We continue to benefit from our considerable presence in emerging markets, our innovative sales and marketing programs and our new product launches.

Sales were $509.1 million, compared with $442.6 million in the prior year, an increase of 10% in local currency sales. Reported sales growth was 15%, which included a 5% currency benefit. By region, local currency sales growth was 9% in Europe, 4% in the Americas and 21% in Asia / Rest of World. Adjusted operating income amounted to $76.5 million, a 15% increase over the prior year amount of $66.8 million.

Cash flow from operations was $76.1 million, compared with $76.2 million in 2007. The Company repurchased 681,600 shares of its stock for $69.5 million during the quarter.

Outlook 2008 / 2009

The Company stated that greater uncertainty in the global economy today makes forecasting particularly challenging. The guidance for fourth quarter 2008 and full year 2009, as detailed below, is based on management’s current assessment of the outlook for their end markets and the global economy.

EPS in the fourth quarter of 2008 is expected to be in the range of $1.88 to $1.90, which results in an estimate of EPS for the full year 2008 in the range of $5.83 to $5.85.

Adjusted EPS for the fourth quarter 2008 is expected to be in the range of $1.90 to $1.92. For the full year 2008, Adjusted EPS is expected to be in the range of $5.74 to $5.76. This compares with previous full year guidance of $5.53 to $5.63 and represents a 21% to 22% increase over 2007 Adjusted EPS of $4.74. Adjusted EPS excludes the after-tax amortization of purchased intangibles and discrete tax items.

For 2009, the Company expects local currency sales growth to be in the range of 2% to 4%. This would result in 2009 EPS of $6.12 to $6.32. Adjusted 2009 EPS is estimated to be in the range of $6.20 to $6.40. Using the mid-points of 2009 and 2008 Adjusted EPS, this represents an increase of approximately 10%. Purchased intangibles amortization in 2009 is estimated at $0.08 and is excluded from Adjusted EPS.

Conclusion

Filliol concluded, “Mettler-Toledo is a high-quality franchise built on market-leading positions, a strong global presence, a track record of innovation and a culture of execution. We benefit from our diversification in terms of products, geographies, industry segments and customers. As we look to 2009, we are concerned about the impact of a potential economic slowdown in our markets. In anticipation of a possible slowdown, we are taking extra efforts to ensure sales resources are allocated to the markets with highest-growth potential and undertaking measures to contain expense growth. We will continue to closely monitor conditions and adapt our plans accordingly. Despite these uncertainties, we remain confident in our ability to execute and, based on our current assessment of the outlook for our end markets, believe we can again generate solid earnings growth in 2009.”
