SCHEDULE 13D/A: Foresite Capital Funds Update Alumis Inc. Stake to 15.9% Following Share Dilution
Beneficial Ownership Update
Foresite Capital and its affiliated entities, including James B. Tananbaum, have filed an amended Schedule 13D for Alumis Inc., reporting an aggregate beneficial ownership of 15.9% of common stock, a decrease in percentage due to the Issuer's issuance of additional shares.
Summary
- This Amendment No. 2 to Schedule 13D updates the beneficial ownership of Alumis Inc. common stock by Foresite Capital Fund VI, L.P., Foresite Capital Fund V, L.P., Labs Co-Invest V, LLC, Foresite Capital Opportunity Fund V, L.P., Foresite Labs Fund I, L.P., Foresite Labs Affiliates 2021, LLC, and their respective general partners/managing members, including James B. Tananbaum.
- The filing is necessitated by a decrease of over 1% in the aggregate percentage ownership reported by the Reporting Persons since the previous Amendment No. 1, primarily due to dilution from Alumis Inc.'s issuance of additional common stock.
- As of May 21, 2025, James B. Tananbaum, through his various affiliations, beneficially owns an aggregate of 15,197,954 shares of Alumis Inc. common stock, representing 15.9% of the total 95,819,723 shares outstanding.
- The Reporting Persons hold their securities for investment purposes and may, from time to time, acquire additional shares, retain, or sell portions of their holdings based on market conditions and the Issuer's prospects.
- The document details a history of significant investments by Foresite Capital entities in Alumis Inc. since February 2021, including purchases of common stock, convertible preferred stock (Series Seed, A, B-1, B-2, C), and convertible promissory notes, totaling tens of millions of dollars.
- Recent open market purchases by Fund VI include 25,000 shares on May 2, 2025, at $4.62 per share ($115,500 total), and 20,000 shares on May 6, 2025, at $4.34 per share ($86,800 total).
Sentiment
Score: 6
Explanation: The document is a routine regulatory filing updating beneficial ownership due to dilution. While the percentage ownership decreased, the underlying investment intent remains 'for investment purposes,' and recent open market purchases indicate continued interest. There are no overtly negative or positive operational details about the company itself, making the sentiment neutral to slightly positive due to continued investment.
Positives
- The continued significant aggregate beneficial ownership by Foresite Capital and James B. Tananbaum (15.9%) indicates a substantial and ongoing investment commitment to Alumis Inc.
- The detailed history of investments demonstrates a long-term engagement and belief in the company's potential, spanning multiple financing rounds from Series Seed to Series C and participation in the IPO.
- Recent open market purchases by Foresite Capital Fund VI in May 2025 suggest continued confidence in the Issuer's stock at current price levels.
Negatives
- The primary reason for this amendment is the dilution of the Reporting Persons' aggregate percentage ownership by over 1% due to Alumis Inc.'s issuance of additional shares, which reduces their proportional stake in the company.
Future Outlook
The Reporting Persons hold their securities for investment purposes and may, from time to time, acquire additional shares, retain, or sell all or a portion of their common stock holdings in the open market or privately negotiated transactions. Any future actions will depend on factors such as stock price levels, general market and economic conditions, ongoing evaluation of Alumis Inc.'s business, financial condition, operations, and prospects, and the attractiveness of alternative investment opportunities. No present plans or intentions are disclosed that would result in or relate to major corporate transactions like mergers, liquidations, or changes in management or control.
