Named Executive Officers, Footnote

Amounts represent compensation reported in the Summary Compensation Table for our CEO, Steve Downing, for the respective years shown.

Non-PEO NEOs included in the Average Calculations for each year presented are: Neil Boehm, Kevin Nash, Matt Chiodo, and Scott Ryan.

Peer Group Issuers, Footnote

The peer group used for purposes of this disclosure is the Russell 3000 Automobiles and Parts Supersector Index, which we also utilize in the stock performance graph provided in our annual report pursuant to Item 201(e) of Regulation S-K. For purposes of disclosure in our 2023 proxy statement, we used the Dow Jones Auto Index (the "Prior Peer Group"). We believe the Russell 3000 Automobiles and Parts Supersector Index is a better comparative index than the Prior Peer Group due to the limited number of companies used in the Prior Peer Group and the Company's outsized impact on the performance of the Prior Peer Group. The 2023 retention grant was based on the TSR of the Russell 3000 Automobiles and Parts Supersector. The TSR for the Prior Peer Group for each respective year reported in the table is as follows: $117.51 as of December 31, 2020; $142.18 as of December 31, 2021; $104.59 as of December 31, 2022; $104.54 as of December 31, 2023; and $81.90 as of December 31, 2024.
