| Item 4. | Ownership | |
| (a) | Amount beneficially owned:
Items 5 through 9 and 11 of each of the cover pages to this Amendment No. 7 are incorporated herein by reference. Set forth below is the aggregate number of shares of Common Stock ("Common Stock") of Rhythm Pharmaceuticals, Inc. (the "Issuer") directly held by each of Baker Brothers Life Sciences, L.P. ("Life Sciences") and 667, L.P. ("667", and together with Life Sciences, the "Funds") which may be deemed to be indirectly beneficially owned by the Reporting Persons, as well as Common Stock that may be acquired upon conversion of Series A Convertible Preferred stock (the "Series A Convertible Preferred"), which is a Common Stock equivalent that votes as a single class with the Common Stock contingent upon Hart-Scott-Rodino Antitrust clearance and only to the extent such Series A Convertible Preferred could be converted into Common Stock pursuant to the beneficial ownership limitations on conversion described below, and that is convertible at any time on a 1-for-20.8333 basis without consideration into Common Stock, subject to the beneficial ownership limitations on conversion described below.
The percentage of beneficial ownership for each of the Reporting Persons reported herein and the information set forth below is based on 63,223,727 shares of Common Stock outstanding as of February 24, 2025, as reported in the Issuer's Form 10-K filed with the Securities and Exchange Commission on February 28, 2025. Such percentage figures are calculated in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act").
The Series A Convertible Preferred is only convertible to the extent that after giving effect or immediately prior to such exercise the holders thereof, their affiliates and any persons who are members of a Section 13(d) group with the holders or one of their affiliates would beneficially own in the aggregate, for purposes of Rule 13d-3 under the Exchange Act, no more than 4.99% of the outstanding Common Stock (the "Maximum Percentage"). By written notice to the Issuer, the Funds may from time to time increase or decrease the Maximum Percentage applicable to that Fund to any other percentage not in excess of 19.99%. Any such increase will not be effective until the 61st day after such notice is delivered to the Issuer. Due to such Maximum Percentage, the Funds cannot presently convert any of the Series A Convertible Preferred.
As a result of these restrictions, the number of shares of Common Stock that may be issued upon conversion of the Series A Convertible Preferred by the above holders may change depending upon changes in the outstanding Common Stock.
Pursuant to the management agreements, as amended, among the Adviser, the Funds and their respective general partners, the Funds' respective general partners relinquished to the Adviser all discretion and authority with respect to the investment and voting power of the securities held by the Funds, and thus the Adviser has complete and unlimited discretion and authority with respect to the Funds' investments and voting power over investments.
The Adviser GP is the sole general partner of the Adviser. The Adviser GP, Felix J. Baker and Julian C. Baker as managing members of the Adviser GP, and the Adviser may be deemed to be beneficial owners of securities of the Issuer directly held by the Funds. | |
| (b) | Percent of class:
The Funds beneficially own 5,604,483 shares of Common Stock directly held by the Funds or 8.9% of the outstanding Common Stock. 667 beneficially owns 0.8% and Life Sciences beneficially owns 8.1% of the outstanding Common Stock. | |
| (c) | Number of shares as to which the person has:
| |
| (i) Sole power to vote or to direct the vote:
