The Peer Group TSR set forth in this table utilizes a custom group of peer companies, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The comparison assumes $100 was invested for the period starting June 30, 2021, through the end of the listed year in the Company and in the custom group of peer companies used in our performance graph, respectively. The Company’s fiscal year peer group consists of IPG Photonics Corp., Wolfspeed Inc., Lumentum Holdings, Inc., Corning, Inc., MKS Instruments, Inc., and Honeywell International, Inc. Historical stock performance is not necessarily indicative of future stock performance.

We determined Adjusted EBITDA to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2026. See discussion under “Annual Cash Incentive Programs” and “Primary Bonus Program (GRIP)” in our CD&A for an explanation of Adjusted EBITDA, and Appendix B for a reconciliation of this non-GAAP measure to its most directly comparable financial measure calculated and presented in accordance with GAAP. Adjusted EBITDA may not have been the most important financial performance measure for prior years, and we may determine a different financial performance measure to be the most important financial performance measure in future years.
