Appendix A

Acquisition and financing-related expenses include costs associated with our M&A activities. We believe these costs are not representative of the Company's operational performance and it is therefore more meaningful to analyze results with the costs excluded. For the twelve months ended December 28, 2024, the charges $0.7 of other miscellaneous M&A costs.

Restructuring activities include activities within our Hydraulics segment related to the creation of our two new Regional Operational Centers of Excellence ("CoE") which are nearing completion. We also continue to add capabilities and activities to our recently expanded Tijuana, Mexico facility to support our Electronics segment. Initial efforts have focused on circuit board assembly and wire harness production. We have also recently initiated some restructuring activities to better optimize our European regional operations. We are transitioning some manufacturing of manifolds and integrated package assembly to our Roncolo, Italy location. These activities include in part the transferring of equipment and operations between facilities. We believe these costs are not representative of the Company's operational performance and it is therefore more meaningful to analyze results with the costs excluded. For the twelve months ended December 28, 2024, the charges include non-recurring labor costs of $2.5 million and manufacturing relocation and other costs of $2.8 million.

Acquisition integration activities include costs associated with integrating our recently acquired businesses, which can occur up to 18 months after acquisition date. We believe these costs are not representative of the Company's operational performance and it is therefore more meaningful to analyze results with the costs excluded. For the twelve months ended December 28, 2024, the costs totaled $0.3 million.

Amortization of intangible assets presented here includes $1.6 million for capitalized software development costs included within cost of sales in the income statement for the twelve months ended December 28, 2024.
