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.”
