Explanation of Responses:

( 1 )The reporting person received a grant of limited partnership interests in JBG Smith Properties LP, JBG Smith Properties' (the "Issuer's") operating partnership (the "OP") designated as Formation Units ("Formation Units") pursuant to the JBG SMITH Properties 2017 Omnibus Share Plan. Formation Units are a class of units in the OP similar to "net exercise" stock option awards, that are convertible by the holder, once vested, into a number of vested limited partnership units of the OP designated as LTIP Units ("LTIP Units"), determined by the increase in the value of a common share of the Issuer, par value $0.01 (a "Common Share") at the time of conversion over the value of a Common Share at the time the Formation Unit was granted. [footnote continued] ( 2 )[Continued from footnote] Vested LTIP Units into which Formation Units have been converted are further convertible at the option of the holder, conditioned upon minimum allocations to the capital accounts of the LTIP Units for federal income tax purposes, into an equal number of OP Units. The resulting OP Units are redeemable by the holder for one Common Share per OP Unit or the cash value of a Common Share, at the Issuer's option, after the two year anniversary of the issuance of the Formation Units. The Formation Units will vest 25% on each of the third and fourth anniversaries, and 50% on the fifth anniversary, of the closing of the Combination, subject to continued employment through each vesting date.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
