(1) Represents the aggregate grant date fair values of stock awards granted to our named executive officers. The amounts reported in this column d o not reflect whether the named executive officer has actually realized a financial benefit from the related awards. In the case of Mr. Wells, by virtue of his resignation in April 2025, all stock awards granted to him during fiscal 2025 and all unvested awards granted to him during prior fiscal years were forfeited.

The grant date fair values of stock awards are computed in accordance with Accounting Standards Codification Topic 718 (ASC Topic 718). For a discussion of the assumptions and methodologies used to calculate the grant date fair value of stock awards in this proxy statement, please refer to Note B of the financial statements in our annual report on Form 10-K for the fiscal year ended June 27, 2025.

The grant date fair values of stock awards reported in this Summary Compensation Table and the other tables in the "Tabular Executive Compensation Disclosure" section of this proxy statement are different than the grant date target values for such awards that are reported in the Compensation Discussion and Analysis. The amounts that appear in the Compensation Discussion and Analysis reflect our practice of valuing stock awards based on the average per share closing price of Mercury's common stock over the 30 days prior to the date of grant, while the amounts that appear in the Tabular Executive Compensation Disclosure section are calculated using the closing price of Mercury common stock only on the grant date itself. In addition, the grant date values ascribed to awards of PSUs discussed in the Compensation Discussion and Analysis assume that the target level of performance for these awards will be achieved, while the values reported for these awards in the Tabular Executive Compensation Disclosure section are based on a Monte-Carlo simulation model that may result in a different expectation of performance at the time of grant. For a further discussion, see Note 2 below.

(2) The fiscal 2025 amounts reported for PSUs in this column reflect the grant date fair value of such awards based on a Monte-Carlo valuation of each award on the date of
