No. 1968/004880/06) (Incorporated in the Republic of South Africa) JSE, NYSE, DIFX Share Code: GFI ISIN Code: ZAE000018123 (Gold Fields or the Company) GOLD FIELDS BOARD STANDS BEHIND EXISTING TERMS OF TRANSACTION WITH YAMANA GOLD 1. INTRODUCTION Shareholders are referred to the announcements published by Gold Fields on 31 May 2022, 11 July 2022, 4 October 2022, 24 October 2022 and 4 November 2022 (Previous Announcements) regarding the proposed acquisition of all the issued and outstanding common shares of Yamana Gold Inc. (Yamana) pursuant to a plan of arrangement (the Transaction). Capitalised terms not defined in this announcement have the meaning given to such terms in the Previous Announcements as applicable. 2. THE BOARD BELIEVES THE GOLD FIELDS TRANSACTION REMAINS SUPERIOR TO THE JOINT OFFER 2.1 The Gold Fields Board (the Board) has convened to consider the Joint Offer of Pan American Silver Corp. (Pan American) and Agnico Eagle Mines Limited (Agnico) to acquire all of the issued and outstanding common shares of Yamana, based on the information included in the joint press release issued by Pan American and Agnico on 4 November 2022 and the press release issued by Yamana the same day. 2.2 Having considered this information in consultation with its financial and legal advisers, the Board continues to believe that the Gold Fields Transaction remains strategically and financially superior to the Joint Offer. Gold Fields believes 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. Gold Fields' proven financial, technical and ESG track record make it the right custodian for the combined assets. 2.3 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. 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. 2.4 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 have a reasonable basis.

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 authorisation that may be required for the Transaction is not obtained or is obtained subject to conditions
