  1. This transaction occurred prior to the Issuer's registration of a class of equity securities under Section 12 of the Securities Exchange Act of 1934, as amended, in connection with the Issuer's initial public offering ("IPO"), and is reported herein pursuant to Rule 16a-2(a). On March 13, 2026, the Issuer repurchased 127,523 shares of the Reporting Person's Common Stock at the fair market value of the Issuer's Common Stock as of March 13, 2026 (for an aggregate purchase price of $4,876,106) as repayment for the Reporting Person's promissory note. On May 7, 2020, the Issuer issued to the Reporting Person's trust, Bao Trust Dated Mar-10 2020, a convertible note with a principal amount of approximately $270,628 (the "2020 Note"). The 2020 Note accrues non-compounding interest at a rate of 4.0% per annum and matures seven years following the date of issuance, unless earlier converted pursuant to its terms. At the execution of the underwriting agreement in connection with the IPO, the outstanding principal balance of the 2020 Note plus any accrued and unpaid interest automatically converted into shares of Common Stock at a ratio based on a conversion price equal to $340.0 million plus any consideration paid by the noteholder for the 2020 Note divided by the Issuer's fully-diluted capitalization on August 5, 2020. Represents an award of restricted stock units ("RSUs"), which vests on the earlier of (i) the one-year anniversary of the award's vesting commencement date and (ii) immediately before the Issuer's first annual meeting following the award's vesting commencement date, subject to the Reporting Person's continuous service to the Issuer. Represents the withholding of shares of Common Stock upon the exercise of the Stock Warrant; not an open market transaction. Each share of the Issuer's convertible preferred stock automatically converted into one share of Common Stock upon the closing of the Issuer's IPO.

open-market sale financial
"transaction_action: "open-market sale""
An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
restricted stock units ("RSUs") financial
"Represents an award of restricted stock units ("RSUs"), which vests"
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
convertible note financial
"issued to the Reporting Person's trust ... a convertible note with a principal amount"
A convertible note is a type of loan that a company gets from investors, which can later be turned into company shares instead of being paid back in cash. It matters because it helps startups raise money quickly without setting a fixed value for the company right away, making it easier to grow and attract investors.
Stock Warrant financial
"Represents the withholding of shares of Common Stock upon the exercise of the Stock Warrant"
Convertible Notes financial
"security_title: "Convertible Notes""
Convertible notes are a type of short-term loan that a company receives from investors, which can later be turned into company shares instead of being paid back in cash. They matter to investors because they offer a way to support a company early on while giving the potential to own a stake in its success if the company grows and later raises more funding.
initial public offering ("IPO") financial
"in connection with the Issuer's initial public offering ("IPO")"
A company’s first sale of stock to the public through a stock exchange, marking its move from private ownership to public ownership. For investors it creates a new opportunity to buy a stake early, sets a market price for the business, and often brings higher attention and volatility—think of a local bakery that used to be family-run finally selling shares so the whole neighborhood can own a piece; that change affects value, control and risk.
