1 The reporting person is the beneficial owner of 5,605,129 shares of the Issuer’s Common Stock which constitute approximately 17.2% of the class outstanding. The percentage calculation assumes that there are currently 32,527,537 outstanding shares of Common Stock of the Issuer, based upon the closing of the Issuer’s initial public offering, as reported in the Issuer’s prospectus filed with the Securities and Exchange Commission (“SEC”) on July 13, 2020.
| CUSIP No. 65487U108 | 13D |
SCHEDULE 13D
| Item 1. | Security and Issuer |
This Schedule 13D (the “Statement”) relates to common stock, par value $0.0001 per share (the “Common Stock”), of Nkarta, Inc., a Delaware corporation (the “Issuer”). The address of the principal executive offices of the Issuer is: 6000 Shoreline Court, Suite 102, South San Francisco, CA 94080.
| Item 2. | Identity and Background |
(a) This Schedule 13D is being filed on behalf of RA Capital Management, L.P. (“ RA Capital”), Peter Kolchinsky, and Rajeev Shah. RA Capital, Dr. Kolchinsky, and Mr. Shah are collectively referred to herein as the “Reporting Persons”.
The Common Stock reported herein includes 4,282,785 shares held by RA Capital Healthcare Fund, L.P. (the “Fund”), 568,033 shares held in a separately managed account (the “Account”), and 754,311 shares held by RA Capital Nexus Fund, L.P. (the “Nexus Fund”). RA Capital Healthcare Fund GP, LLC is the general partner of the Fund and RA Capital Nexus Fund GP, LLC is the general partner of the Nexus Fund. The general partner of RA Capital is RA Capital Management GP, LLC, of which Dr. Kolchinsky and Mr. Shah are the controlling persons. RA Capital serves as investment adviser for the Fund, the Account, and the Nexus Fund and may be deemed a beneficial owner, for purposes of Section 13(d) of the Securities Exchange Act of 1934 (the “Act”), of any securities of the Issuer held by the Fund, the Account, or the Nexus Fund. The Fund and the Nexus Fund have delegated to RA Capital the sole power to vote and the sole power to dispose of all securities held in the Fund’s and the Nexus Fund’s portfolio, including the shares of the Issuer’s Common Stock reported herein. Because the Fund and the Nexus Fund have divested themselves of voting and investment power over the reported securities they hold and may not revoke that delegation on less than 61 days’ notice, the Fund and the Nexus Fund disclaim beneficial ownership of the securities they hold for purposes of Section 13(d) of the Act and therefore disclaim any obligation to report ownership of the reported securities under Section 13(d) of the Act. As managers of RA Capital, Dr. Kolchinsky and Mr. Shah may be deemed beneficial owners, for purposes of Section 13(d) of the Act, of any securities of the Issuer beneficially owned by RA Capital. RA Capital, Dr. Kolchinsky, and Mr. Shah disclaim beneficial ownership of the securities reported in this Schedule 13D Statement (the “Statement”) other than for the purpose of determining their obligations under Section 13(d) of the Act, and the filing of the Statement shall not be deemed an admission that either RA Capital, Dr. Kolchinsky, or Mr. Shah is the beneficial owner of such securities for any other purpose.
(b) The business address of each of the Reporting Persons is: 200 Berkeley Street, 18th Floor, Boston, MA 02116.
(c) The Fund and the Nexus Fund are private investment vehicles. RA Capital provides investment management services to the Fund, the Account, and the Nexus Fund. The principal occupation of Dr. Kolchinsky and Mr. Shah is investment management.
(d) None of the Reporting Persons have, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).
(e) None of the Reporting Persons have, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.
| CUSIP No. 65487U108 | 13D |
(f) See Item 6 of the cover pages.
| Item 3. | Source and Amount of Funds or Other Consideration |
Prior to the Issuer’s initial public offering (the “IPO”), the Reporting Persons caused the Fund, the Account, and the Nexus Fund to purchase equity interests in the Issuer’s predecessor in a private placement, and those interests automatically converted into 2,271,796 shares of Common Stock immediately upon completion of the IPO. The Fund, the Account, and the Nexus Fund also purchased 3,333,333 shares of Common Stock from the underwriters of the IPO. All purchases were for cash and were funded by working capital of the Fund, the Account, and the Nexus Fund.
| Item 4. | Purpose of Transaction |
The Reporting Persons acquired the Common Stock reported herein for investment purposes and not with an intent, purpose or effect of changing control of the Issuer. Although the Reporting Persons currently have no plan or proposal to acquire any additional Common Stock or to dispose of any of the Common Stock reported herein, the Reporting Persons may acquire additional Common Stock from time to time or dispose of Common Stock they beneficially own, consistent with their investment purposes and in amounts to be determined by the Reporting Persons based upon a number of factors, including, without limitation, their ongoing assessment of the Issuer's business prospects, prevailing market conditions, the availability of other investment opportunities, and/or other considerations.
In addition, consistent with their investment purpose, the Reporting Persons may engage in communications with persons associated with the Issuer, including shareholders of the Issuer, officers of the Issuer and/or members of the board of directors of the Issuer, to discuss matters regarding the Issuer, including but not limited to its operations and strategic direction. Dr. Zachary Scheiner, a principal of RA Capital, currently serves as a director of the Issuer and therefore will engage in regular discussions with the Issuer’s board of directors and management as part of his duties as a director.
The Reporting Persons have no plans or proposals that relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of the instructions to Item 4 of Schedule 13D.
The Reporting Persons may, however, change their purpose and formulate and implement plans or proposals with respect to the Issuer at any time and from time to time. Any such action may be made by the Reporting Persons alone or in conjunction with other shareholders, potential acquirers, financing sources and/or other third parties and could include one or more purposes, plans or proposals that relate to or would result in actions required to be reported herein in accordance with Item 4 of Schedule 13D.
| Item 5. | Interest in Securities of the Issuer |
(a) and (b) See Items 7-11 of the cover pages and Item 2 above.
| CUSIP No. 65487U108 | 13D |
(c) The following table lists the Reporting Persons’ transactions in Common Stock that were effected during the sixty day period prior to the filing of this Schedule 13D:
| Transaction | Date | No. Shares | Price |
