STANDARD LITHIUM LTD.

Share-based compensation

The Company may grant options (“Options”) under its stock option plan and performance share units (“PSUs”), restricted share units (“RSUs”) and deferred share units (“DSUs”) under its long-term incentive plan to directors and employees. The Company expenses the fair value of Options, PSUs, RSUs and DSUs granted over the vesting period, with a corresponding increase in equity.

Share-based payments to employees are measured at the fair value of the instruments issued and are amortized over the vesting period, which is the period over which all of the specific vesting conditions are satisfied. For awards with graded vesting, the fair value of each tranche is recognized over its respective vesting period.

Share-based payments to non-employees are measured at the fair value of goods or services received, or the fair value of the equity instruments issued if it is determined that the fair value of the goods or services cannot be reliably measured and are recorded at the date the goods or services are received. The offset to the recorded cost is to Options reserve. Consideration received on the exercise of Options is recorded as share capital and the related Option reserve is transferred to share capital. Upon expiry of Options, the recorded value is transferred to deficit.

Where the terms and conditions of Options are modified before they vest, the increase in the fair value of the Options, measured as the difference noted before and after the modification, is also charged to profit or loss over the remaining vesting period.

Where a grant of Options is cancelled and settled during the vesting period, excluding forfeitures when vesting conditions are not satisfied, the Company immediately accounts for the cancellation as an acceleration of vesting and recognizes the amount that otherwise would have been recognized for services received over the remainder of the vesting period. Any payment made to the employee on the cancellation is accounted for as the repurchase of an equity interest except to the extent the payment exceeds the fair value of the equity instrument granted, measured at the repurchase date. Any such excess is recognized as an expense.
