Explanation of Responses:

( 1 )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 thegreater 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 accumulateddividends, 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 themaximum 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 TSRpercentile 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. ( 2 )These market share units cliff vest on the third anniversary of the grant date, subject to certification of performance results by the Board. ( 3 )Each performance share converts into one share of common stock upon distribution in the first quarter of 2028, subject to certification of performance results by the Board.
