Having considered this information in consultation with its financial and legal advisers, the Board continues to believe that the Gold Fields Transaction, as jointly announced by Gold Fields and Yamana on May 31, 2022, remains strategically and financially superior to the Joint Offer. Consequently, the Board has unanimously determined that it will not offer to change the terms of the Transaction. In coming to this determination, the Board has taken into account its commitment to capital discipline and considered the fairness of the Transaction to both Gold Fields and Yamana shareholders over the long term. Chris Griffith, Chief Executive Officer of Gold Fields, says: “The Board was unanimous in its decision not to offer to change the terms of the Transaction as we continue to believe our Transaction is strategically and financially superior. We believe in the highly complementary fit of Yamana's operating assets and its extensive pipeline of future growth projects will create significant near-term and long-term value for the shareholders of both Gold Fields and Yamana when added to Gold Fields’ current portfolio of assets.

2 Gold Fields’ proven financial, technical and ESG track record make it the right custodian for the combined assets.” As previously advised, Gold Fields will continue to work towards completion of the Transaction on its current terms for the benefit of the shareholders of both companies in accordance with the Arrangement Agreement. The meeting of Yamana Shareholders to approve the Transaction is scheduled for 21 November 2022. For a copy of the Yamana Circular in relation to that meeting please see Yamana’s profile at www.sedar.com and its website at www.yamana.com. The Gold Fields General Meeting to approve the Transaction is scheduled for 22 November 2022.

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

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’ 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 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

7 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 authorisation that may be required for the Transaction is not obtained or is obtained subject to conditions that are not anticipated; 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 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 details of potential risk and uncertainties affecting the combined business operations of Gold Fields and Yamana after the Transaction are described in the Circular.
