Explanation of Responses:

( 1 )These restricted stock units will vest on August 2, 2025. ( 2 )Each restricted stock unit converts into one share of common stock upon vesting. ( 3 )One-half of these restricted stock units will vest on each of September 1, 2025 and September 1, 2026. ( 4 )One-third of these restricted stock units will vest on each of June 3, 2025, June 3, 2026, and June 3, 2027. ( 5 )These restricted stock units will cliff vest on the third anniversary of the grant date on March 10, 2028. ( 6 )These market share units will vest on March 10, 2026. ( 7 )Each market share unit converts into the number of shares of common stock determined by applying a payout factor to the target number of shares vesting on a given date. The payout factor is a ratio of the average of the closing price on the measurement date plus the nine prior trading days divided by the average stock price on the grant date (also a 10-day average). The minimum payout factor that must be achieved to earn a payout is 80% and the maximum payout factor is 225%. ( 8 )One-half of these market share units will vest on each of March 10, 2026 and March 10, 2027. ( 9 )These market share units cliff vest on the third anniversary of the grant date, subject to certification of performance results by the Board. ( 10 )Each market share unit converts into the number of shares of common stock determined by applying a payout factor to the target number of shares vesting on a given date. The payout factor is the greater of Total Return and relative total shareholder return (rTSR) Floor. Total Return is a ratio of the 10-day average closing stock price on the measurement date, plus the value of accumulated dividends, divided by the average stock price on the grant date (also a 10-day average). The minimum payout factor for Total Return performance that must be achieved to earn a payout is 80% and the maximum is 225%. The rTSR Floor feature provides a minimum level of payout if BMS stock price declines from the grant date but outperforms our peers based on their TSR percentile rank. A TSR percentile rank (i) below the 50th percentile yields a 0% payout, (ii) between the 50th and 74.99th percentiles yields a 50% payout, and (iii) at or above the 75th percentile yields a 100% payout. ( 11 )Each performance share converted into one share of common stock upon distribution in the first quarter of 2026 in accordance with the terms of the award and certification of performance results by the Board. ( 12 )Each performance share converted into one share of common stock upon distribution in the first quarter of 2027 in accordance with the terms of the award and certification of performance results by the Board.
