On September 26, 2016, Fulgent Genetics, Inc. filed Amendment No. 2 to its Registration Statement on Form S-1 (File No. 333-213469) (the “Registration Statement”), including the preliminary prospectus included therein (the “Preliminary Prospectus”), in connection with the offering of 4,600,000 shares of its common stock. The Preliminary Prospectus was filed to supplement certain information that was provided in the preliminary prospectus dated September 19, 2016 related to the offering (the “Initial Preliminary Prospectus”). This free writing prospectus summarizes the material supplements to the Initial Preliminary Prospectus that appear in the Preliminary Prospectus. Amendment No. 2 to the Registration Statement, including the Preliminary Prospectus included therein, may be accessed through the following link to the web site of the Securities and Exchange Commission (the  “SEC”):

Immediately prior to closing its initial public offering, Fulgent Genetics, Inc. will complete a reorganization (the “Reorganization”) in which Fulgent Therapeutics LLC will become a wholly owned subsidiary of Fulgent Genetics, Inc., as is described in more detail in the Registration Statement. For purposes of this free writing prospectus: “Fulgent LLC” refers to Fulgent Therapeutics LLC; “Fulgent Inc.” refers to Fulgent Genetics, Inc.; and “Fulgent,” the “company,” “we,” “us” and “our” refer, for periods prior to completion of the Reorganization, to Fulgent LLC and, for periods after completion of the Reorganization, to Fulgent Inc. and its consolidated subsidiary after giving effect to the Reorganization.



Disclosure has been added under the heading “Certain Relationships and Related Party Transactions—Tax Distributions,” which appears on page 115 of the Preliminary Prospectus, to disclose the amounts we expect to pay to the former members of Fulgent LLC after completion of this offering, consistent with the terms of Fulgent LLC’s operating agreement. The added disclosure is otherwise consistent with disclosure that appears in other sections of the Initial Preliminary Prospectus.
