Segment Realignment

In the second quarter of 2025, the Company realigned its Hardware and Protective Solutions segment to include the sales of accessories, which are now managed by the Hardware and Protective Solutions leadership team. Previously, accessories were included in the Robotics and Digital Solutions segment and managed by that leadership team.

If the aforementioned changes in segments were in effect for the thirteen weeks ended March 29, 2025 and March 30, 2024, and the years ended December 28, 2024, December 30, 2023, and December 31, 2022, net sales for our Hardware and Protective Solutions segment would have been higher by $3.6 million, $3.4 million, $13.6 million, $15.9 million and $17.4 million, respectively, and net sales for our Robotics and Digital Solutions segment would have been lower by $3.6 million, $3.4 million, $13.6 million, $15.9 million and $17.4 million, respectively.

In addition, the changes to the significant segment expenses and segment Adjusted EBITDA did not have a material impact on the financial statements as of March 29, 2025, March 30, 2024, December 28, 2024, December 30, 2023, or December 31, 2022.
