Due to an administrative error, upon the vesting of restricted stock units on 1/4/2017, 620 shares of common stock were withheld to satisfy tax withholding obligations as if the reporting person were an employee of the issuer. This error was corrected and the improperly-withheld 620 shares of common stock were issued to the reporting person on 4/3/2017. Restricted stock units convert into common stock on a one-for-one basis. On January 4, 2016, the reporting person received restricted stock units under Iradimed Corporation's 2014 Equity Incentive Plan. The restricted stock units vest in two equal annual installments beginning on January 4, 2017. Upon vesting, the reporting person will receive a number of shares of common stock equal to the number of restricted stock units that have vested. This option, representing a right to purchase a total of 26,250 shares, was granted on 1/1/2014 and vests over 4 years in equal annual installments commencing on the first anniversary of the grant date. /s/ Monty K Allen 2017-04-05
