The Convertible Preferred Stock reported herein automatically converted immediately prior to the closing of the Issuer's initial public offering (the "IPO") into 6,840,213 shares of Class A Common Stock without payment of additional consideration. The Convertible Preferred Stock had no expiration date. 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. Following the conversion of all outstanding shares of the Issuer's Convertible Preferred Stock, Class B common stock, Class C common stock, and Convertible Promissory Notes (the "Notes") into shares of Class A Common Stock immediately prior to the closing of the IPO, each share of Class A Common Stock was then reclassified into one share of common stock ("Common Stock") in a transaction exempt from Section 16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") pursuant to Rule 16b-7 thereunder (the "Reclassification"). The Notes were originally issued on September 17, 2025, with the Reporting Person acquiring a Note with a principal amount of $1,000,000. The Notes earned interest at a rate of 8% annually until March 31, 2026, and thereafter earned interest at a rate of 15% annually until repaid or converted. The Notes included a conversion feature providing for automatic conversion into Class A Common Stock at or immediately prior to the closing of the IPO at a 10% discount to the IPO price per share. As a result of the IPO pricing on July 30, 2026, at a price of $16 per share, this Note automatically converted into shares of Class A Common Stock immediately prior to the closing of the IPO on August 3, 2026, at a conversion price of $14.40. The Notes were scheduled to mature on September 17, 2027, but converted automatically upon the closing of the IPO on August 3, 2026, prior to the maturity date.
