Item. 1.        Security and Issuer
This Amendment No. 2 (“Amendment No. 2”) to the statement on schedule 13D originally filed with the U.S. Securities and Exchange Commission (the “Commission”) on March 21, 2022, as amended by Amendment No. 1 filed on March 27, 2023 (the “Statement”) relates to the voting common stock, par value $0.0001 per share (the “Common Stock”), of Longboard Pharmaceuticals, Inc., a Delaware corporation (the “Issuer”). On January 4, 2024, the Issuer filed with the Commission the Issuer’s Prospectus Supplement for the offering of up to 11,500,000 shares of the Company’s Common Stock, that included up to 1,500,000 Shares that may be sold pursuant to the exercise of an option to purchase additional shares, and reporting 33,846,954 shares of Common Stock (or 35,346,954 shares if the underwriters exercise their option to purchase additional shares of Common Stock in full) outstanding immediately after the offering. On January 8, 2024, the Issuer released a press release announcing the closing of the offering and the exercise of the underwriters’ option to purchase additional shares in full. The Issuer’s offering resulted in a decrease in the percentage of the outstanding shares of Common Stock beneficially owned by the Reporting Persons. This Amendment No. 2 to the Statement is being filed solely to reflect a decrease in the percentage of the outstanding shares of Common Stock beneficially owned by the Reporting Persons as a result of the increase in the outstanding shares of Common Stock of the Issuer as a result of an offering of Common Stock by the Issuer as reported in the Issuer’s Prospectus Supplement and January 8, 2024 press release.
Except as specifically provided herein, this Amendment No. 2 does not modify any of the information previously reported in the Statement.  Capitalized terms used but not otherwise defined in this Amendment No. 2 shall have the meanings ascribed to them in the Statement.
Item 2.Identity and Background
Item 2 of the Statement is amended to incorporate the following sentence at the end of the section captioned “(a)—(c)”:
“Schedule I attached hereto is amended and restated in its entirety as of the date of Amendment No. 2 to the Statement.”

Item 5.Interest in Securities of the Issuer

The following amends and restates the information set forth in the first paragraph of Item 5 of the Statement, captioned “(a)—(b)” in its entirety.
(a)—(b)    As of the date of the Statement, as amended by Amendment No. 2, the Reporting Persons hold 3,978,540 shares of Common Stock, representing approximately 11.26% of the outstanding shares of Common Stock. The percentage is calculated based on 35,346,954 shares of Common Stock outstanding immediately after the offering reported in the Issuer’s Prospectus Supplement, filed with the Commission on January 4, 2024 and the press release of the Issuer, dated January 8, 2024, that “Announces Closing of Public Offering of Common Stock and Full Exercise of Underwriters’ Option to Purchase Additional Shares.” The Issuer’s offering resulted in a decrease in the percentage of the outstanding shares of Common Stock beneficially owned by the Reporting Persons. The decrease in the percentage of shares of Common Stock beneficially owned by the Reporting Persons reported on this Amendment No. 2 resulted solely from the increase in the number of shares of Common Stock reported as outstanding by the Issuer as a result of an offering of Common Stock by the Issuer as reported in the Issuer’s Prospectus Supplement and January 8, 2024 press release.
The following amends and restates the information set forth in the fourth paragraph of Item 5 of the Statement, captioned “(c)” in its entirety.
(c) Except as reported in the Statement, as amended by this Amendment No. 2, neither the Reporting Person nor any of the individuals listed on Schedule I has effected any transactions in the Common Stock during the past sixty (60) days.
