Ordinary Shares
Each ordinary share entitles the holder to one vote on all matters submitted to a vote of the Company’s shareholders. Ordinary shareholders are entitled to receive dividends, if any, as may be declared by the board of directors. Through June 30, 2025, no cash dividends had been declared or paid by the Company.

At-the-Market Facility
On October 8, 2021, the Company entered into a Sales Agreement with Cowen and Company, LLC, or Cowen, under which the Company was permitted to issue and sell from time to time up to $150.0 million of its ADSs, each representing one ordinary share, through Cowen as the sales agent. Pursuant to the Sales Agreement dated October 8, 2021, through February 27, 2025, we sold 5,491,836 ADSs under our ATM offering program, resulting in $54.8 million in net proceeds. On February 27, 2025, the Company entered into a new Sales Agreement under which the Company may issue and sell from time to time up to $150.0 million of our ADSs, subject to the terms of the Sales Agreement. Sales of the Company’s ADSs, if any, will generally be made at market prices. To date, the Company has not sold any ADSs under this Sales Agreement.
Warrants
Equity-classified
On June 30, 2023, the Company entered into a Warrant Agreement with Hercules, which provides Hercules with the right to purchase a number of the Company’s Ordinary Shares, equal to the quotient derived by dividing (i) the amount equal to (a) 2.5% times (b) the aggregate principal amount of term loan advances made and funded under the Loan Agreement by (ii) the exercise price. Upon receipt of each term loan, the Warrant will automatically become exercisable and will expire in 10 years (on June 30, 2033). On June 30, 2023, with the receipt of the first term loan, 94,222 shares became exercisable to Hercules with a fair market value of $0.7 million.

On August 18, 2023, in connection with the PIPE, the Company issued and sold warrants to purchase up to 16,076,750 ADSs, each representing one ordinary share, at a purchase price of $9.93 per ADS. The PIPE Warrants became exercisable for a three year period beginning in February 2024. Through June 30, 2025, PIPE Warrants were exercised for 3,752,050 ADSs, resulting in $37.3 million in exercise proceeds. During the three months ended June 30, 2025, no PIPE warrants were exercised.

Liability-classified
On January 13, 2025, in connection with the 2025 Financing, the Company issued and sold (i) 24,014,728 ADSs, each representing one ordinary share, (ii) in lieu of ADSs, Pre-funded Warrants to purchase up to 11,044,720 ADSs, and (iii) accompanying 2025 ADS Warrants to purchase up to 11,044,720 ADSs, each representing one ordinary share. The Pre-funded Warrants have an exercise price of $0.0001 per ADS and are exercisable immediately. The Pre-funded Warrants expire when exercised in full. The 2025 ADS Warrants have an exercise price of $5.7960 per ADS and are exercisable following a specified data milestone. The 2025 ADS Warrants will expire three years after such warrants become exercisable. Once the ADS Warrants become exercisable, the Company may force the exercise of the 2025 ADS Warrants (by way of cash or cashless exercise, at the Company’s option), in whole or in part, by delivering a notice of forced exercise to the holders, provided that the closing price for the Company’s ADSs on Nasdaq exceeded the warrant exercise price of $5.796 for the three consecutive trading days prior to the date on which the notice of forced exercise is delivered.
The 2025 Financing comprising of ADSs, Pre-funded Warrants and 2025 ADS Warrants, resulted in aggregate proceeds of $149.8 million, with issuance costs of $9.4 million. Since the Pre-funded Warrants and 2025 ADS Warrants have been classified as a liability and recorded at fair value with changes in fair value recorded in the condensed consolidated income statement, the aggregate proceeds have been allocated first to these warrants at their respective fair values at the issuance date. The residual has been allocated to the ADSs issued as part of the 2025 Financing and recognized within equity.
