Peer Group Issuers, Footnote     Peer Group TSR represents the weighted cumulative total return on $100 invested on March 31, 2021 through the last trading day of the applicable fiscal year reported in the table, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the Nasdaq Biotechnology Index for all fiscal years disclosed, which aligns with the peer group used for the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report on Form 10-K for the year ended March 31, 2026.        
Adjustment To PEO Compensation, Footnote     The dollar amounts reported below represent the amount of “compensation actually paid” to our PEO and Non-PEO executive officers (as an average) as computed in accordance with Item 402(v) of Regulation S-K, for each covered fiscal year. The dollar amounts do not reflect the actual amount of compensation earned or received by or paid to the PEOs and Non-PEO executive officers during the applicable fiscal year. For purposes of the equity award adjustments shown below, no dividends or other earnings paid on stock or option awards in the covered fiscal year prior to the vesting date were not otherwise included in the total compensation for the covered fiscal year. In calculating the “compensation actually paid” amounts reflected in these columns, the fair value or change in fair value, as applicable, of the equity award adjustments included in such calculations was computed in accordance with ASC Topic 718. The valuation assumptions used to calculate such fair values did not materially differ from those disclosed at the time of grant and any incremental fair value associated with modified awards are reflected in the valuation assumptions at each vesting date and at the end of the covered year for outstanding modified awards. The following table details the applicable adjustments that were made to determine “compensation actually paid” for the fiscal year ended March 31, 2026 (all amounts are averages for Non-PEO executive officers):
