[1] Includes realized and unrealized gains and losses on derivative currency forward and option contracts not designated as hedging instruments. For contracts not designated as hedging instruments, we realized losses of $1,136 and $2,692 for the three months ended September 30, 2026 and 2025, respectively. Refer to Note 4 for additional details relating to our derivative contracts.
[2] Currency-related losses, net primarily relates to significant non-functional currency intercompany financing relationships that we may change at times and are subject to currency exchange rate volatility.
[3] In the periods in which a net loss is recognized, the impact of share options, PSUs, RSUs and warrants is excluded from shares used in computed diluted net loss per share as it is anti-dilutive.
[4] On May 1, 2020, we entered into a financing arrangement which included 7-year warrants to purchase 1,055,377 of our ordinary shares with a strike price of $60. The effect of the warrants on our weighted-average shares outstanding for a period is dilutive if the average market price of our ordinary shares during the period was higher than the strike price of the warrants and anti-dilutive if the average market price of our ordinary shares during the period was lower than the strike price of the warrants.
