On October 26, 2020, Turning Point Therapeutics, Inc. (the “Company”) filed with the Securities and Exchange Commission (the “SEC”) a preliminary prospectus supplement (the “Preliminary Prospectus”) pursuant to Rule 424(b) under the Securities Act of 1933, as amended, relating to its Registration Statement on Form S-3ASR (File No. 333-238300) filed with the SEC on May 15, 2020, in connection with a proposed public offering. In the Preliminary Prospectus, the Company disclosed that it had approximately $711.4 million of cash, cash equivalents and marketable securities as of September 30, 2020 and that, after giving effect to an assumed issuance and sale of $400.0 million of shares in the proposed public offering and after deducting the underwriting discounts and commissions and estimated offering expenses payable by the Company, the Company would have had approximately $1,088.4 million of cash, cash equivalents and marketable securities as of September 30, 2020. These amounts are unaudited and do not present all information necessary for an understanding of the Company’s financial condition as of September 30, 2020. The review of the Company’s financial statements for the quarter ended September 30, 2020 is ongoing and could result in changes to these amounts.
