The realization of this deferred tax asset is dependent upon the generation of future taxable income in certain jurisdictions during the periods in which the Company’s deferred tax assets are available. The Company considers whether it is probable that all or a portion of the deferred tax assets will not be realized. In making this assessment, management considers all available evidence, including recent financial operations, projected future taxable income and tax planning strategies. Based on projections of future taxable income over the periods in which the deferred tax assets are available, realization of these deferred tax assets is probable and consequently the deferred tax assets have been recorded.

Tax rate reconciliation The provision for income taxes differs from the amount computed by applying the combined expected federal and provincial income tax rate to earnings before income taxes. The reasons for these differences are as follows: 2022 2021 Earnings (loss) before income taxes and non-controlling interest $ 84,795 $ (103,855) Combined federal and provincial tax rate 26.9% 26.9% Computed income tax expense (recovery) 22,810 (27,937) Increase (decrease) in taxes resulting from: Difference between Canadian rates and rates applicable to subsidiaries in other countries 8,986 28,690 Change in unrecognized deferred tax assets 1,234 22,068 Income in equity-accounted investee (25,264) (24,481) Change in uncertain tax positions (6,282) 1,099 Bargain purchase gain (6,129) - Other permanent differences 176 (640) Income tax recovery $ (4,469) $ (1,201) E. Earnings and income taxes by jurisdiction 2022 2021 Earnings (loss) before income taxes Canada $ 99,944 $ 58,624 Foreign (15,149) (162,479) $ 84,795 $ (103,855) Current income taxes Canada $ 2,260 $ 2,257 Foreign 5,413 1,990 $ 7,673 $ 4,247 Deferred income tax recovery Canada $ (10,178) $ (3,937) Foreign (1,964) (1,511) $ (12,142) $ (5,448) Income tax recovery $ (4,469) $ (1,201) F. Reassessments Canada On February 18, 2021, the Supreme Court of Canada (Supreme Court) dismissed Canada Revenue Agency’s (CRA) application for leave to appeal the June 26, 2020 decision of the Federal Court of Appeal (Court of Appeal). The dismissal means that the dispute for the 2003, 2005 and 2006 tax years is fully and finally resolved in the Company’s favour. In September 2018, the Tax Court of Canada (Tax Court) ruled that the marketing and trading structure involving foreign subsidiaries, as well as the related transfer pricing methodology used for certain intercompany uranium sales and purchasing agreements, were in full compliance with Canadian law for the tax years in question. Management believes the principles in the decision apply to all subsequent tax years, and that the ultimate resolution of those years will not be material to Cameco’s financial position, results of operations or liquidity in the year(s) of resolution. The total tax reassessed for the three tax years was $ 11,000,000 , and Cameco remitted 50 %. In 2021, Cameco received refunds totaling about $ 5,500,000 plus interest. In addition, on April 30, 2019, the Tax Court had awarded Cameco $ 10,300,000 for legal fees incurred, plus an amount for disbursements of up to $ 16,700,000 . As a result of additional information provided by the Tax Court, $ 12,200,000 for disbursements was recognized as a reduction of administration expense in 2021. If CRA continues to pursue reassessments for tax years subsequent to 2006, Cameco will continue to utilize its appeal rights under Canadian federal and provincial tax rules. G.
