Each restricted stock unit ("RSU") represents a contingent right to receive one share of RDNT common stock. Amount reported is net of 1,060 restricted stock awards transferred pursuant to a domestic relations order. Subject to the reporting person's continued service, twenty-percent (20%) of the RSUs will vest on March 10, 2026; the remaining eighty-percent (80%) will vest in three equal annual installments with one-third (1/3) vesting on each of March 10, 2027, 2028, and 2029, or the first business day thereafter if such date falls on a weekend or holiday, respectively. RDNT shares will be delivered to the reporting person in exchange for vested RSUs on the earlier of (i) the reporting person's separation from service, (ii) the reporting person's death or disability, (iii) a change in control of RadNet, or (iv) in equal annual installment payments over five years beginning on January 10, 2028.
