Forward-looking Statements This announcement contains “forward-looking statements” which are intended to be covered by the safe harbor created by applicable laws and “forward-looking information” within the meaning of applicable Canadian securities laws. Where a forward-looking statement expresses or implies an expectation or belief as to future events or results, such expectation or belief is expressed in good faith and believed to have a reasonable basis. However, such statements are subject to risks, uncertainties and other factors, which could cause actual results to differ materially from future results expressed, projected or implied by the forward-looking statements. Undue reliance should not be placed on such statements. Forward-looking statements often address our expected future business and financial performance and financial condition, and often contain words such as “anticipate,” “intend,” “plan,” “will,” “would,” “estimate,” “expect,” “goal,” “believe,” “target,” “indicative,” “preliminary,” or “potential.” Forward-looking statements in this announcement may include, without limitation: statements relating to the Transaction and the expected terms, timing of the Yamana and Gold Fields meetings, timing and closing of the Transaction, including receipt of required approvals and satisfaction of other customary closing conditions; expectations related to a TSX listing; anticipated Transaction synergies; estimates of future production; estimates of future costs applicable to sales and all-in sustaining costs; estimates of future growth rates; climate-related statements, targets and metrics, expectations regarding future exploration and the development, growth and potential of the Combined Group’s operations, project pipeline and investments, including, without limitation, project returns, capital costs, capital intensity, annual production, and feasibility study schedules; expectations of future dividends including targeting paying a dividend at the top end of Gold Fields’ revised dividend policy; expectations of returns to shareholders; expectations of future free cash flow generation, liquidity, balance sheet strength and credit ratings; expectations of future plans and benefits; expectations regarding mineral reserves and mineral resources, grade and recoveries; estimates of future closure costs and liabilities; the Combined Group constituting a new senior gold producer and the attributes thereof; leadership in sustainability and the ability to develop various projects. Estimates or expectations of future events or results are based upon certain assumptions, which may prove to be incorrect. Such assumptions, include, but are not limited to: there being no significant change to current geotechnical, metallurgical, hydrological and other physical conditions at Gold Fields and Yamana’s properties and operations; permitting, development, operations and expansion of Gold Fields’ and Yamana’s operations and projects being consistent with current expectations and mine plans; the TSX approving Gold Fields’ listing application; attaining the necessary normalised earnings to enable Gold Fields to pay the expected; political developments in any jurisdiction in which Gold Fields or Yamana operate being consistent with current expectations; certain exchange rate assumptions for the Australian dollar, South African rand or the Canadian dollar to the U.S. dollar, as well as other exchange rates being approximately consistent with current levels; certain price assumptions for gold, copper, silver, zinc, molybdenum and oil; prices for key supplies being approximately consistent with current levels; the accuracy of current mineral reserve and mineral resource estimates; and other planning assumptions. Risks relating to forward-looking statements in regard to Gold Fields’ and Yamana’s business and future performance may include, but are not limited to, volatility in the price of gold and other metals, currency fluctuations, operational risks, supply chain shortages, rising inflation, increased production costs and variances in ore grade or recovery rates from those assumed in mining plans, political and country risk, community relations, increased regulation of environmental and sustainability matters, the impact of climate change on Gold Fields’ and Yamana’s operations, conflict resolution governmental regulation and judicial outcomes and other risks. In addition, material risks that could cause actual results to differ from forward-looking statements include: the inherent uncertainty associated with financial or other projections; the prompt and effective integration of Gold Fields’ and Yamana’s businesses; the risk associated with Gold Fields’ and Yamana’s ability to obtain required shareholder approval of the Transaction; timing of completion of the Transaction, including the risk that the conditions to the Transaction are not satisfied on a timely basis or at all and the failure of the Transaction to close for any other reason; the risk that a consent or authorization that may be required for the Transaction is not obtained or is obtained subject to conditions that are not anticipated; the risk that the TSX approval for the listing is not obtained; the risk that earnings are not as expected; the outcome of any legal proceedings that may be instituted against the parties and others related to the arrangement agreement; unanticipated difficulties or expenditures relating to the Transactions, the response of business partners and retention as a result of the announcement and pendency of the Transactions; potential volatility in the price of the Gold Fields Shares or Gold Fields ADSs due to the Transaction; the anticipated size of the markets and continued demand for Gold Fields’ and Yamana’s resources and the impact of competitive responses to the announcement of the Transaction; and the diversion of management time on Transaction-related issues. Further details of potential risks and uncertainties affecting Gold Fields and Yamana are described in Gold Fields’ filings with the JSE and the United States Securities and Exchange Commission, including the Gold Fields’ Integrated Annual Report 2021 and annual report on Form 20-F filed with the United States Securities and Exchange Commission on 31 March 2022 (SEC File no. 001-31318) and Yamana’s most recent annual information form as well as its other filings made with the securities regulatory authorities in all provinces of Canada and available at www.sedar.com, and Yamana’s most recent annual report on Form 40-F filed with the United States Securities and Exchange Commission.
