About these balances

Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

F1 · shares: As previously reported on a Form 4 filed on September 17, 2020 by the Reporting Person, the Reporting Person reported acquiring stock options to purchase 130,000 shares of common stock. However, Organovo Holdings, Inc. (the "Company") subsequently determined that stock options to purchase 65,000 shares of common stock under the Company's 2012 Equity Incentive Plan, as amended (the "Plan"), were not validly granted pursuant to the Plan because they exceeded the Plan limit on the number of stock options that may be granted to any one person during any calendar year. Accordingly, the attempted grant of these excess stock options was ineffective, and they were never granted to the Reporting Person. The Reporting Person is filing this amendment to report the correct amount of stock options acquired.
