First Quarter Results

Patrick Kaltenbach, President and Chief Executive Officer, stated, “We are pleased with our first quarter results as we delivered good performance in an increasingly uncertain market environment. Solid execution of our margin initiatives supported very good Adjusted EPS growth.”

GAAP Results

EPS in the quarter was $8.33, compared with the prior-year amount of $7.81.

Compared with the prior year, total reported sales increased 7% to $947.1 million. By region, reported sales increased 3% in the Americas, 12% in Europe, and 8% in Asia/Rest of World. Earnings before taxes amounted to $209.7 million, compared with $201.9 million in the prior year.

Non-GAAP Results

Adjusted EPS was $8.91, an increase of 9% over the prior-year amount of $8.19.

Compared with the prior year, total sales in local currency increased 3%. By region, local currency sales increased 2% in the Americas, 1% in Europe, and 5% in Asia/Rest of World. Excluding acquisitions, first quarter local currency sales increased 1%, including flat sales in the Americas and 3% growth in Asia/Rest of World. Adjusted Operating Profit amounted to $246.2 million, compared with the prior-year amount of $236.7 million.

Adjusted EPS and Adjusted Operating Profit are non-GAAP measures. Reconciliations to the most comparable GAAP measures are provided in the attached schedules.

Outlook

Management cautions that market conditions are uncertain and could change quickly. Based on today's assessment, management anticipates local currency sales for the second quarter of 2026 will increase approximately 3%. Adjusted EPS is forecast to be $10.70 to $10.85, a growth rate of 6% to 8%.

For the full year 2026, management anticipates local currency sales will increase approximately 4%. Adjusted EPS is forecast to be in the range of $46.30 to $46.95, representing growth of approximately 8% to 10%. This compares with previous local currency sales growth guidance of approximately 4% and Adjusted EPS guidance of $46.05 to $46.70.

The Company does not provide GAAP financial measures on a forward-looking basis because we are unable to predict with reasonable certainty and without unreasonable effort the timing and amount of future restructuring and other non-recurring items.

Conclusion

Kaltenbach concluded, “Our investments in innovation continue to provide tangible benefits and also position us strongly to capitalize on our customers’ investments in automation, digitalization, and onshoring in the future. While we recognize increased uncertainty in the macroeconomic environment, we remain confident in our agility and the strong execution of our growth and margin expansion programs to achieve solid Adjusted EPS growth this year.”
