 does not expect its estimates to be materially different from amounts
actually incurred, if TuHURA’s estimates of the status and timing of services performed differ from the actual status and timing of services performed, it could result in TuHURA reporting amounts that are too high or too low in any particular
period. To date, there have been no material differences between TuHURA’s estimates of such expenses and the amounts actually incurred.

Stock-Based Compensation Expense

Stock-based compensation expense represents the cost of the grant date fair value of equity awards recognized over the requisite service period
of the awards (usually the vesting period) on a straight-line basis. TuHURA estimates the fair value of equity awards using the Black-Scholes option pricing model and recognizes forfeitures as they occur. Estimating the fair value of equity awards
as of the grant date using valuation models, such as the Black-Scholes option pricing model, is affected by assumptions regarding a number of variables, including the risk-free interest rate, the expected stock price volatility, the expected term of
stock options, the expected dividend yield and the fair value of the underlying common stock on the date of grant. Changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation expense is
recognized. These inputs are subjective and generally require significant analysis and judgment to develop. See Note 2 of TuHURA’s financial statements for information concerning certain of the specific assumptions TuHURA used in applying the
Black-Scholes option pricing model to determine the estimated fair value of TuHURA’s stock options granted.

Common stock valuations

TuHURA is required to estimate the fair value of the common stock underlying its equity awards when performing fair value
calculations. The fair value of the common stock underlying its equity awards was determined on each grant taking into account input from management and taking into account the pricing offered in TuHURA’s equity raises. All options to purchase
shares of TuHURA Common Stock are intended to be granted with an exercise price per share no less than the fair value per share of TuHURA Common Stock underlying those options on the date of grant, based on the information known to TuHURA on the
date of grant. In the absence of a public trading market for TuHURA Common Stock, on each grant date TuHURA develops an estimate of the fair value of its common stock in order to determine an exercise price for the option grants. TuHURA’s
determinations of the fair value of its common stock
