        <footnote id="F1">Reflects securities of Fulgent Therapeutics LLC (the &quot;Predecessor&quot; or &quot;Fulgent LLC&quot;). Fulgent LLC is considered the predecessor of Fulgent Genetics, Inc. (the &quot;Issuer&quot;) following completion of a reorganization transaction pursuant to which the Predecessor became a wholly owned subsidiary of the Issuer (the &quot;Reorganization&quot;), which was completed on September 30, 2016 in connection with the initial public offering of the Issuer and which is described in the Issuer's Registration Statement on Form S-1, as amended (File No. 333-213469). In the Reorganization, all of the Predecessor's Class D voting common units were cancelled in exchange for shares of the Issuer's common stock at a ratio of 7.6-for-1.</footnote>
        <footnote id="F2">The securities were disposed of and cancelled in the Reorganization in exchange for 1,767,659 shares of the Issuer's common stock.</footnote>
        <footnote id="F3">The securities were received in the Reorganization in exchange for the cancellation of 13,434,211 Class D voting common units of the Predecessor.</footnote>
