Explanation of Responses:

Id	Content
F1	The Reporting Person's indirect beneficial ownership includes 59 shares of the Issuer's common stock held in the Issuer's 401(k) plan, which were previously reported but were inadvertently omitted from a prior Form 4 filing.
F2	This award vests following the conclusion of a three-year performance period that began on January 1, 2026 and ends on December 31, 2028 (the "Performance Period"). This award survives termination of employment due to death, disability, termination by the Company without cause or retirement by the employee upon having reached 62 years of age. In all cases, the shares will vest, if at all, on December 31, 2028, following the conclusion of the Performance Period as follows: 50% of the award will vest if the Company is in the top 35th percentile of Return on Invested Capital ("ROIC") among the Bloomberg Peer Group ("BPG"), 100% of the award will vest if the Company is in the top 55th percentile of ROIC among the BPG, and 175% of the award will vest if the Company is at or above the 85th percentile of ROIC among the BPG, as measured and determined by the Compensation Committee at the end of the Performance Period.
F3	The number of common shares vesting pursuant to the award will be interpolated on a straight-line basis between the 35th and 55th percentile of ROIC (equivalent to 50% up to 100% of the award) and again between the 55th and 85th percentile of ROIC (equivalent to 100% up to 175% of the award). The number of common shares that could vest over 100% of the award up to the maximum of 175% of the award, if any, will be reduced by one-half if absolute total shareholder return for the Performance Period is negative, as measured and determined by the Compensation Committee at the end of the Performance Period.
