        <footnote id="F1">The reporting person received a grant of limited partnership units of JBG Smith Properties LP, JBG Smith Properties' (the &quot;Issuer's&quot;) operating partnership (the &quot;OP&quot;), designated as LTIP Units (&quot;LTIP Units&quot;) pursuant to the JBG SMITH Properties 2017 Omnibus Share Plan. These LTIP Units are a class of units in the OP that are 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 Operating Partnership Units (&quot;OP Units&quot;) in the OP. The resulting OP Units are redeemable by the holder for one common share of the Issuer, par value $0.01 (a &quot;Common Share&quot;) per OP Unit or the cash value of a Common Share, at the Issuer's option, after the two year anniversary of the LTIP issuance. The LTIP Units will be fully vested on the date of grant but may not be sold while the reporting person serves as a trustee, except in certain circumstances.</footnote>
