The assumptions used in determining fair value of the share options that vested during 2024, or that were outstanding and unvested as of December 31, 2024, as applicable, are as follows:

2024

Risk-free interest rate

3.5% - 4.8%

Expected volatility

62.8% - 74.9%

Expected dividend yield

0%

Expected term (in years)

3.0 - 6.2

(4)Cumulative Total Shareholder Return (“TSR”) illustrates the value, as of the last day of the indicated fiscal year, of an investment of $100 in our ordinary shares on December 31, 2020, calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period. The Peer Group TSR set forth in this table utilizes the Nasdaq Biotechnology Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K in our Annual Report on Form 10-K.
(5)The dollar amounts reported represent the amount of net loss reflected in the Company’s audited financial statements for the applicable year.
