(1)	Each share of convertible Preferred Stock is convertible into one share of Class A common stock ("Class A Common Stock") at any time at the option of the holder into such number of fully paid and non-assessable shares of Class A Common Stock as is determined by dividing the original issuance price of each series of convertible Preferred Stock by each series' conversion price in effect at the time of conversion, and will automatically convert immediately prior to the closing of the Issuer's initial public offering (the "IPO") into the number of shares shown in Column 3 without payment of additional consideration, which shares will then be reclassified into shares of common stock ("Common Stock") pursuant to the Reclassification (as defined below). The convertible Preferred Stock has no expiration date.
(2)	Frances Anne Elizabeth Richard, Jill Marie Franklin, Peter Stuart Allenby Edwards, and Cheung Ka Ho are the directors of Morningside Venture Investments Limited ("Morningside") and share voting and dispositive power with respect to the securities held by Morningside and MVIL, LLC, Morningside's wholly-owned subsidiary. Ms. Richard, Ms. Franklin, Mr. Edwards, and Mr. Cheung each disclaim ownership of the securities owned by Morningside and MVIL, LLC.
(3)	The Convertible Promissory Note (the "Note") was originally issued on September 17, 2025, and includes a conversion feature providing for automatic conversion upon the closing of the IPO. As a result of the IPO pricing on July 30, 2026, the conversion price will equal 90% of the IPO offering price, contingent upon the closing of the IPO.
(4)	The Note matures on September 17, 2027, but will convert automatically upon the closing of the IPO prior to the maturity date.
(5)	Following the conversion of all outstanding shares of the Issuer's Preferred Stock, Class B common stock, and Class C common stock into shares of Class A Common Stock and the reclassification of each share of Class A Common Stock into one share of Common Stock in an exempt transaction pursuant to Rule 16b-7 (the "Reclassification"), in each case immediately prior to the closing of the IPO, the principal amount of the Note (together with accrued interest thereon) will convert upon the closing of the IPO into shares of Common Stock at a conversion price equal to 90% of the IPO price per share.
(6)	Represents securities held by MVIL, LLC.
