(8) The vesting of PSU matching awards granted during fiscal 2025 is contingent on the Company earning at least $1 in aggregate adjusted EBITDA for the four fiscal quarters corresponding to the 2025 calendar year. Subject to the satisfaction of this performance condition, the final number of shares of our common stock earned by the participant in respect of these awards will be calculated based on the matching formula set forth in Note 7 above as well as our prior 30-day average closing stock price at the time the performance condition and matching formula criteria are evaluated (which will occur during the first quarter of calendar 2026). The amount disclosed in the Estimated Future Payouts Under Equity Incentive Plan Awards columns for PSU matching awards represents the number of shares of our common stock that would be earned by the plan participant assuming: (a) the satisfaction of the adjusted EBITDA performance condition, (b) the aggregate value of the participant's actual DCMP deferrals and eligible cash compensation for calendar 2025 is consistent with our expectations at the time of grant, and (c) our prior 30-day average closing stock price at the time the performance condition and matching formula criteria are evaluated is $39.29, which represents our prior 30-day average closing stock price on the date the PSU matching awards were granted.

(9) The amount disclosed in the Grant Date Fair Value of Stock and Option Awards column for PSU matching awards is based on the grant date closing price of our common stock of $43.30, multiplied by the number of shares reported for the award in the Estimated Future Payouts Under Equity Incentive Plan Awards columns.
