a.The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” and “Option Awards” columns in the Summary Compensation Table for the applicable year.

b.The equity award adjustments for each applicable year include, if applicable, the addition (or subtraction, as applicable) of the following:

i.the year-end fair value of any equity awards granted in the applicable year that were outstanding and unvested as of the end of the year;

ii.the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that were outstanding and unvested as of the end of the applicable year;

iii.for awards that were granted and vested in the applicable year, the fair value as of the vesting date;

iv.for awards granted in prior years that vested in the applicable year, the amount equal to the change in fair value as of the vesting date (from the end of the prior fiscal year);

v.for awards granted in prior years that failed to meet the vesting conditions during the applicable year, a deduction for the amount equal to the fair value at the end of the prior fiscal year; and

vi.the dollar value of any dividends or other earnings paid on stock or option awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year.

The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. The amounts deducted or added in calculating the equity award adjustments for our PEO are as follows:

Additional 402(v) Disclosure

In 2022, Net Income decreased to $548.7 million while Adjusted EBITDA increased to $1,331.0 million, primarily due to the closing of the Combinations, which resulted in one-time increased costs in 2022, including higher depreciation and amortization expense, acquisition and integration costs and interest expenses (the “Increased Costs”). Specifically, the 2022 decrease in Net Income was impacted by the Increased Costs while the 2022 increase in Adjusted EBITDA was primarily driven by the inclusion of Ortho’s Adjusted EBITDA and the Increased Costs were excluded from Adjusted EBITDA, as described in Note 8 above.
