Wheaton Precious Metals : Fourth Quarter 2023 Financial Statements

Management's Responsibility for Financial Reporting

The accompanying consolidated financial statements of Wheaton Precious Metals Corp. ("Wheaton") were prepared by management, which is responsible for the integrity and fairness of the information presented, including the many amounts that must of necessity be based on estimates and judgments. These consolidated financial statements were prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS"). Financial information appearing throughout our Management's Discussion and Analysis ("MD&A") is consistent with these consolidated financial statements.

In discharging our responsibility for the integrity and fairness of the consolidated financial statements and for the accounting systems from which they are derived, we maintain and rely on a comprehensive system of internal controls designed to ensure that transactions are authorized, assets are safeguarded and proper records are maintained. These controls include business planning; delegation of authority; careful selection and hiring of staff; accountability for performance within appropriate and well-defined areas of responsibility; and the communication of policies and guidelines of business conduct throughout the company.

The Board of Directors oversees management's responsibilities for financial reporting through the Audit Committee, which is composed entirely of directors who are neither officers nor employees of Wheaton. The Audit Committee reviews Wheaton's interim and annual consolidated financial statements and MD&A and recommends them for approval by the Board of Directors. Other key responsibilities of the Audit Committee include monitoring Wheaton's system of internal controls, monitoring its compliance with legal and regulatory requirements, selecting the external auditors and reviewing the qualifications, independence and performance of the external auditors.

Deloitte LLP, Independent Registered Public Accounting Firm, appointed by the shareholders of Wheaton upon the recommendation of the Audit Committee and the Board of Directors, have performed an independent audit of the consolidated financial statements and their report follows. The auditors have full and unrestricted access to the Audit Committee to discuss their audit and related findings.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Wheaton Precious Metals Corp. Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Wheaton Precious Metals Corp. and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of earnings, comprehensive income, shareholders' equity, and cash flows, for each of the two years in the period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and its financial performance and its cash flows for each of the two years in the period ended December 31, 2023, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 14, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Impairment - Assessment of Whether Indicators of Impairment or Impairment Reversal Exist within the Mineral Stream Interests - Refer to Note 4.3 to the financial statements

Critical Audit Matter Description

The Company considers each precious metals purchase agreement ("PMPA") to be a separate cash generating unit ("CGU"). The Company's determination of whether or not an indicator of impairment or impairment reversal exists at the CGU level requires significant management judgment. Changes in metal price forecasts, discount rates, reductions or increases in the amount of future recoverable ounces of metals attributable to the Company and/or adverse or favorable operational, political or regulatory developments impacting the mining properties in respect of which the Company has PMPAs can result in a write-down or write-up of the carrying amounts of the Company's mineral stream interests.

While there are several factors that are required to determine whether or not an indicator of impairment or impairment reversal exists, the judgments with the highest degree of subjectivity are evaluating the impact of (1) changes to future metal prices for gold, silver, palladium and cobalt, and (2) changes in the amount of future recoverable ounces of metals attributable to the Company. Auditing these estimates and factors required a high degree of subjectivity in applying audit procedures and in evaluating the results of those procedures. This resulted in an increased extent of audit effort, including the involvement of fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures to evaluate the impact of changes to (1) future metal prices for gold, silver, palladium and cobalt and (2) changes in the amount of future recoverable ounces of metals attributable to the Company in the assessment of indicators of impairment or impairment reversal included the following, among others:

• Evaluated the effectiveness of the Company's controls over management's assessment of indicators of impairment or impairment reversal.
• Evaluated management's ability to accurately forecast future recoverable ounces of metals attributable to the Company by:
• • Assessing the methodology used in management's determination of the future recoverable ounces of attributable metals;
  • Completing retrospective analysis comparing the Company's historical forecasts to actual results;
  • Comparing management's expected future recoverable ounces of attributable metals to reserve and resource estimates prepared by the third-party mining property operators; and
  • Considering the professional qualifications and objectivity of management's specialists.
• With the assistance of fair value specialists, evaluated the significance of movements in future metal prices for gold, silver, palladium and cobalt by comparing historical forecasts to current third-party forecasts.

3. provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of Wheaton's assets that could have a material effect on Wheaton's financial statements.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements on a timely basis. Also, projections of any evaluation of the effectiveness of internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
