Senior Management Changes

The Company announced that Shawn Vadala, Chief Financial Officer, will join the Group Management Committee (GMC). The Company also announced that Oliver Wittorf, Head of Supply Chain, will also assume responsibility for IT and the Company's Blue Ocean initiative and will join the GMC. Mr. Vadala and Mr. Wittorf will continue to report to Bill Donnelly, Executive Vice President. These management changes will take place on January 1, 2017, and have been undertaken to ensure a smooth transition as Mr. Donnelly will gradually reduce his time commitment and plans to retire at the end of 2018.

Filliol commented on the management changes, "Both Shawn and Oliver are strong leaders with extensive experience and proven track records over many years at METTLER TOLEDO. I am confident they will be strong contributors to the GMC and will further the development of the Finance, Supply Chain, IT and Blue Ocean functions. I am very pleased that we have orchestrated a very smooth and well-planned succession for Bill Donnelly and that we can continue to leverage Bill's unique contribution to the Company for another two years."

Outlook

The Company updated its outlook for 2016 and noted that forecasting remains challenging.

Based on today’s assessment, management anticipates that local currency sales growth in the fourth quarter 2016 will be approximately 5%, and Adjusted EPS is forecasted to be in the range of $5.08 to $5.13, an increase of 9% to 10%.

For the full year 2016, local currency sales growth is expected to be approximately 6% and Adjusted EPS in the range of $14.61 to $14.66, an increase of approximately 13%. This compares to previous guidance of local currency sales growth of approximately 5% and Adjusted EPS in the range of $14.40 to $14.50.

The Company said that, based on its assessment of market conditions today, management anticipates local currency sales growth in 2017 will be approximately 5%. This sales growth is expected to result in Adjusted EPS in the range of $16.05 to $16.25. Using the midpoint of the 2016 Adjusted EPS, this reflects a growth of 10% to 11%.

Adjusted EPS excludes purchased intangible amortization, discrete tax items, restructuring charges and other one-time items. While the Company has provided an outlook for Adjusted EPS, it has not provided an outlook for EPS as it would require an estimate of non-recurring items, which are not yet known.

Conclusion

Filliol concluded, "Demand in most of our markets is solid. We continue to execute very well and are benefiting from our robust product pipeline, Spinnaker sales and marketing initiatives, Field Turbo investments and our productivity and margin enhancement measures. Assuming market conditions remain stable, we believe we are well-positioned to continue to gain share and generate good sales and earnings growth in 2017 and beyond."
