Purpose of Transaction (Item 4)

Seven Fleet Partners LP

The Reporting Persons purchased the Shares based on the Reporting Persons' belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable. No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in Item 4(a) through (j) of this Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer's financial position and investment strategy, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in …The first part of Item 4 of the SCHEDULE 13D filed 2025-09-18; the filing has the rest

Longitude Capital Partners IV, LLC

The information set forth in Item 3 of this Statement is incorporated herein by reference. The Reporting Persons hold the securities of the Issuer for general investment purposes. The Reporting Persons may, from time to time, depending on prevailing market, economic and other conditions, acquire additional shares of Common Stock or other securities of the Issuer, dispose of any such securities, or engage in discussions with the Issuer concerning such acquisitions or dispositions or further investments in the Issuer. The Reporting Persons intend to review their investment in the Issuer on a continuing basis and, depending upon the price and availability of shares of Common Stock or other securities of the Issuer, subsequent developments affecting the Issuer, the Issuer's business and prospects, other investment and business opportunities available to the Reporting Persons, general stock market and economic conditions, tax considerations and other factors considered relevant, may decide at any time to increase or to decrease the size of their investment in the Issuer in the open market, in privately negotiated transactions, pursuant to 10b5-1 trading plans or otherwise. In addition, Brian Liu, a managing director at LCM, serves on the board of directors of the Issuer.

Seven Fleet Capital Management LP

Item 4 of the Schedule 13D is amended to add the following: The Reporting Persons effected an internal restructuring into a master-feeder structure, pursuant to which Seven Fleet Partners LP contributed, for no consideration, all of the 1,515,151 Shares it then held to Seven Fleet Master Fund LP on October 6, 2025 (the "Contribution Date"). Following the Contribution Date, Seven Fleet Partners LP no longer beneficially owns any securities of the Issuer and has ceased to be a reporting person with respect to this Schedule 13D. The restructuring and contribution did not result in any change to Dr. Liu's pecuniary interest in the Shares. This Amendment is being filed pursuant to Rule 13d-2(a) to reflect material changes in the information previously reported, including (i) the restructuring and contribution described above, which changed the identity of the reporting persons and person-level beneficial ownership, and (ii) a correction to the identity of the investment manager disclosed in the initial Schedule 13D. The initial Schedule 13D incorrectly identified "Seven Fleet Advisors" as a reporting person and as the investment manager. The correct investment manager is Seven Fleet Management, and its general partner is Seven Fleet Management GP.Item 4 of the SCHEDULE 13D/A filed 2025-10-28

Where this comes from

Anyone who comes to own more than 5% of a class of a listed company's voting shares has to tell the SEC. A holder who may seek to change or influence the company files Schedule 13D, and has to say in Item 4, "Purpose of Transaction", what it intends to do. A holder with no such intent, such as many index and passive funds, may file the shorter Schedule 13G. Both are amended when the stake changes, including when it falls below 5%.

Every row here is one of those filings, linked to the filing itself. Percentages and share counts are exactly as the holder filed them, for the holder the filing names; an amendment showing a lower figure is shown as filed. Item 4 text is quoted word for word. Where a 13D's Item 4 contains a sentence stating a definite intent to influence the company, that sentence is marked and quoted; the page does not describe the holder or its motives beyond the words it filed. Nothing here is investment advice.
