Footnote F1

On May 21, 2025, the reporting person was granted financial-based performance share units based on the performance of three key metrics and the payout could be increased to 168% of target or reduced to 24% on achievement of the key metrics. Based on company performance at December 31, 2025, the Compensation Human Resources Committee certified on February 25, 2026 two of the three metrics at 71.5%. The Performance Shares representing the two metrics were certified and are now adjusted for performance are time-based and will vest on December 31, 2027. The final metric is measured over a three year time period ending December 31, 2027, and remains subject to approval, and any accrued dividend equivalents pursuant to this metric are subject to forfeiture if such metric does not achieve the minimum performance attainment. The performance share units have been accumulating quarterly dividend equivalents. Each performance share unit represents the contingent right to receive one common share.
