Salient Features Media Release Poor safety start in Q1 2023 The safety of our people remains our overriding priority. Tragically, in Q1 2023, we had a fatal incident at our Tarkwa mine in Ghana, where a sub-contractor was killed in a workshop accident. Furthermore, two contractors died after a vehicle accident at the Galiano Gold-managed Asanko joint venture (JV), also in Ghana. On behalf of Gold Fields, I would like to extend our deepest condolences to the families of those affected and reiterate our commitment to continuously strengthening our safety systems, standards, and behaviours. Solid operational performance Group attributable equivalent gold production was 577koz, largely flat year on year (YoY) (down 4% quarter on quarter (QoQ)). Group production remains on track to deliver the FY 2023 guidance provided in February 2023. Group AISC for the quarter was US$1,152/oz, also largely flat YoY and up 8% QoQ. AIC for the Group was US$1,343/oz, 2% higher YoY (up 3% QoQ) due to higher capital expenditure at the Salares Norte project. Net debt at the end of the quarter was US$875m, compared to US$704m at the end of December 2022, primarily driven by the payment of the final dividend of US$215m and a non-controlling interest holders dividend of US$3m. The Group generated free cash flow of US$83m in Q1 2023. The balance sheet remains in a very strong position, with net debt to EBITDA at the end of the quarter of 0.36x, compared to 0.29x at the end of Q4 2022. Q1 2023 operational performance The Australian region produced 243koz, down 6% YoY (down 12% QoQ) at AIC of A$1,812/oz (US$1,239/oz) (up 6% YoY and up 16% QoQ) and AISC of A$1,658/oz (US$1,134/oz) (up 3% YoY and up 19% QoQ). South Africa reported Q1 2023 production of 88koz, 13% higher YoY (up 16% QoQ) at AIC of R751,830/kg (US$1,317/oz) (up 7% YoY and down 7% QoQ) and AISC of R751,830/kg (US$1,317/oz) (up 12% YoY and down 1% QoQ). Our mines in Ghana produced 193koz (including 45% of Asanko), down 8% YoY (down 3% QoQ), at AIC of US$1,193/oz (down 2% YoY and down 8% QoQ) and AISC of US$1,169/oz (down 1% YoY and down 8% QoQ). Production at Cerro Corona in Peru was 75koz (gold equivalent), 34% higher YoY, mainly due to lower gold and copper grades mined in the March 2022 quarter in line with the mining plan (up 6% QoQ) at AIC of US$853 per gold equivalent ounce (down 15% YoY and down 15% QoQ) and AISC of US$777 per gold equivalent ounce (down 19% YoY and down 13% QoQ). Update on Salares Norte The Salares Norte project continued to make positive progress during the March quarter. Total construction progress at the end of March was 90.3% compared to 85.7% at the end of Q4 2022. The project is fully staffed with the camp at full capacity. In addition to completing construction, the focus at the project includes dealing with punch list items to ensure successful commissioning. Total project progress was 90.4% as at the end of March 2023 compared to 86.7% at the end of December 2022. Total spend for the March quarter was US$115m, comprising of US$92m in capital expenditure, US$10m in exploration expenditure and a US$13m investment in working capital. 577,000 ounces of attributable production US$1,152 per ounce of all-in sustaining cost US$1,343 per ounce of all-in cost JOHANNESBURG, 04 May 2023: Gold Fields Limited (JSE and NYSE: GFI) is pleased to provide an operational update for the quarter ended 31 March 2023. Detailed financial and operational results are provided on a six-monthly basis i.e. at the end of June and December. Total tonnes mined for the March quarter increased by 14% to 8.9Mt (including 420kt of ore containing 97koz of gold) from 7.8Mt for the December quarter (including 422kt of ore containing 79koz of gold). As a result, there were 176koz on stockpile at the end of March. As guided in February 2023, first production is expected during Q4 2023, with a quick ramp-up in 2024. The project capex remains on track to meet revised guidance of US$1,020m. Outlook and 2023 guidance unchanged Gold Fields remains on track to meet the original production and cost guidance provided in February 2023. Attributable gold equivalent production (excluding Asanko) is expected to be between 2.25Moz – 2.30Moz (2022 comparable was 2.32Moz). AISC is expected to be between US$1,300/oz – US$1,340/oz, with AIC expected to be US$1,480/oz – US$1,520/oz. The exchange rates used for our 2023 guidance are: R/US$17.00 and US$/A$0.70. Integrated reporting At the end of March, we released a suite of reports under the umbrella of the 2022 Integrated Annual Report (IAR). These include the IAR itself, the Annual Financial Report (including our Governance Report), the Mineral Resource and Reserve supplement and the Climate Change Report, produced in line with the recommendations of the Task Force on Climate-related Financial Disclosure (TCFD). This was followed up in early May with the 2022 Report to Stakeholders and the GRI Content Index. Operational update for the quarter ended 31 March 2023

Environmental, social and governance (ESG) highlights In December 2021, we took a significant step by committing to a range of 2030 ESG targets, which we started implementing during 2022. The table below lists our six ESG priorities, the respective 2030 targets and how we performed against these targets during 2022. As part of our market presentation, we will highlight our progress against these priorities.

Gold Fields partners with Osisko to develop the Windfall Project On 2 May, we announced a partnership with Osisko Mining to develop and mine the world class underground Windfall Project in Québec, Canada, now known as the Windfall Mining Group. Under executed and implemented transaction agreements, Gold Fields, through a 100% held Canadian subsidiary, has acquired a 50% interest in the feasibility stage Windfall Project (including exploration potential) on the following key terms: • Cash payment of C$300m (c.US$220m) paid on signing; • Cash payment of C$300m payable on issuance of key permits by the Deputy Minister of Québec’s Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (MELCCFP) to the Partnership authorising the construction and operation of the Windfall Project; and • 50/50 co-share of interim and construction capital expenditures. In addition, we have also acquired a 50% up-front vested interest in Osisko’s highly prospective Urban Barry and Quévillon district exploration camps, totalling approximately 2,400km2 (Exploration Properties), which will be co-explored and co-developed under the Partnership. In exchange, Gold Fields will fund the first C$75m in regional exploration on those Exploration Properties over the first seven years of the Partnership. Delivering on our strategy Our strategy is made of three pillars, as communicated towards the end of 2021 and reaffirmed to the market earlier this year, namely: • Pillar 1: Maximise the potential of our current assets through people and innovation • Pillar 2: Build on our leading commitment to ESG • Pillar 3: Grow the value and quality of our portfolio of assets Our progress against pillar 1 continued during Q1 with the asset optimisation programme kicking off at St Ives and then moving on to Tarkwa. We expect to provide more detail on this work later in 2023. In addition, during the quarter, Gold Fields and AngloGold Ashanti announced an agreement on the key terms of a proposed joint venture between Gold Fields’ Tarkwa and AngloGold Ashanti’s neighbouring Iduapriem mines in Ghana. Initial engagement with the government occurred in March, with formal negotiations expected to commence later in May 2023. This is a good example of a value accretive transaction that is focused on maximising the potential at one of our cornerstone assets. As highlighted above, we continue to make good progress on our six ESG priorities and are on track to meet our 2030 targets. As previously communicated, Gold Fields will continue to look at value accretive inorganic opportunities to bolster our pipeline. These options will include greenfields targets, development projects or bolt-on acquisitions of producing assets. The recently announced partnership with Osisko Mining and the joint venture with AngloGold Ashanti in Ghana demonstrates our commitment to growing the value and quality of our portfolio of assets. Further, adding in Salares Norte, which is expected to come into production at the end of this year, strengthens Gold Fields’ future production profile and enhances its position on the cost curve.

Ore mined decreased by 13% to 2.16Mt in the March quarter from 2.47Mt in the December quarter, however, remained in line with the mine plan, with ore sourced mainly from stages 2 and 3 of the Gruyere pit. Pre-strip activities increased at stage 4 of the pit, resulting in an increase in capital waste mined of 38% to 3.85Mt in the March quarter from 2.80Mt in the December quarter, with first ore extracted from stage 4 in the latter part of the March quarter. As a result of the increased capital waste mined, operational waste mined decreased by 37% to 1.88Mt in the March quarter from 3.01Mt in the December quarter. As a result of the 13% decrease in ore mined and combined with a 3% decrease in mined grade to 1.14g/t in the March quarter from 1.18g/t in the December quarter, gold mined decreased by 16% to 79,000oz in the March quarter from 93,700oz in the December quarter. Tonnes milled increased by 16% to 2.47Mt in the March quarter from 2.13Mt in the December quarter due to increased process plant availability. All-in cost increased by 4% to A$1,575/oz (US$1,077/oz) in the March quarter from A$1,513/oz (US$989/oz) in the December quarter due to a A$4m (US$3m) gold inventory charge to cost in the March quarter compared with a A$9m (US$6m) gold inventory credit to cost in the December quarter, partially offset by increased gold sold. Sustaining capital expenditure for March quarter (on a 50% basis) at A$12m (US$8m) and was similar to the December quarter.

Underground waste mined decreased by 38% to 112,000t in the March quarter from 181,000t in the December quarter due to decreased capital development in the Z110 and Z120 areas and the completion of the second decline. Grade mined decreased by 21% to 5.09g/t in the March quarter from 6.45g/t in the December quarter due to lower grades mined from the Z100, Z110 and Z120 areas in line with the mining plan. As a result of the decrease in the grade of ore mined, partially offset by a 3% increase in ore mined from 398,000t in the December quarter to 410,000t in the March quarter, gold mined decreased by 19% to 67,100oz in the March quarter from 82,700oz in the December quarter. All-in cost increased by 13% to A$1,960/oz (US$1,340/oz) in the March quarter from A$1,734/oz (US$1,140/oz) in the December quarter due to lower gold sales partially offset by decreased capital expenditure.

At the underground operations, ore mined decreased by 10% to 449,000t in the March quarter from 497,000t in the December quarter due to a delay in the power upgrade at Invincible, with expected completion in May as well as delays in the ventilation upgrade due to the incident at Hamlet late in 2022. The plan is to re-commence raise boring in May with expected completion of this work in early Q4. Grade mined from underground operations decreased by 11% to 4.88g/t in the March quarter from 5.47g/t in the December quarter associated with lower grade stopes sequenced in the upper levels of Invincible mine. As a result of the decreased ore mined at lower grades, gold mined decreased by 19% to 70,600oz in the March quarter from 87,300oz in the December quarter. At Neptune open pit stage 7, ore mined increased by 36% to 1,077,000t in the March quarter from 792,000t in the December quarter and grade mined increased by 12% to 1.78g/t in the March quarter from 1.59g/t in the December quarter. Resultant gold mined increased by 52% to 61,600oz in the March quarter from 40,400oz in the December quarter. Operational waste mined decreased by 65% to 0.67Mt in the March quarter from 1.94Mt in the December quarter. Mining activities are scheduled to be concluded at Neptune in the June quarter. Pre-strip activities commenced at the Swiftsure open pit, with 362,000t of capital waste moved during the March quarter (December quarter – nil). The Swiftsure open pit is a small but high-grade open pit that will come into production in the second half of 2023. All-in cost increased by 26% to A$1,578/oz (US$1,079/oz) in the March quarter from A$1,257/oz (US$807/oz) in the December quarter due to increased cost of sales before amortisation and depreciation and higher capital expenditure, partially offset by higher gold sold. The increase in cost of sales before amortisation and depreciation is mainly due to a lower gold inventory credit to cost in the March quarter of A$14m (US$10m) compared with a gold inventory credit to cost of A$38m (US$26m) in the December quarter. Total capital expenditure increased by 12% to A$27m (US$19m) in the March quarter from A$24m (US$15m) in the December quarter. Sustaining capital expenditure increased by 23% to A$21m (US$14m) in the March quarter from A$17m (US$11m) in the December due to the commencement of pre-stripping at the Swiftsure open pit. Non-sustaining capital decreased by 14% to A$6m (US$4m) in the March quarter from A$7m (US$5m) in the December quarter due to timing of infrastructure expenditure at the Invincible Deep underground mine. 9

Underground ore mined decreased by 19% to 253,000t in the March quarter from 313,000t in the December quarter due to unfavourable ground conditions causing sequencing delays in the Kath orebody at Waroonga. Overall grade mined decreased by 8% to 5.79g/t in the March quarter from 6.26g/t in the December quarter with lower grade ore mined from New Holland, in line with the mining plan. As a result of the 19% decrease in ore mined and 8% decrease in grade, gold mined from underground operations decreased by 25% to 47,200oz in the March quarter from 63,100oz in the December quarter. Pre-strip activities at the Barren Lands open pit concluded during the March quarter, with capital waste increasing by 81% to 1.13Mt from 0.63Mt in the December quarter. Ore tonnes mined of 63,000t at an average grade of 2.17g/t for 4,4Koz in the March quarter compared with ore tonnes mined of 3,000t at an average grade of 0.61g/t for 0.1Koz in the December quarter. The Barren Lands open pit will provide the gateway to the Barren Lands and Redeemer Underground Complex. The project also enables access to new underground exploration platforms. All-in cost increased by 23% to A$2,311/oz (US$1,580oz) in the March quarter from A$1,878/oz (US$1,228/oz) in the December quarter primarily due to the 21% decrease in gold sold. Total capital expenditure in the March quarter was similar to the December quarter at A$29 million (US$20m). Sustaining capital expenditure at A$17m (US$12m) for the March quarter was similar to sustaining capital expenditure in the December quarter. Non-sustaining capital expenditure decreased by 10% to A$11m (US$8m) in the March quarter from A$12m (US$8m) in the December quarter with the completion of the Agnew crushing circuit upgrade. 10 Gold Fields Operational update for the quarter ended 31 March 2022

Grade mined decreased by 10% to 5.56 g/t in the March quarter from 6.19 g/t in the December quarter, mainly due to a gravity fall of ground incident in the 100 2B West Cut 3 Main Access Drive compounded by an unexpected holing of the hanging wall into the footwall at the 2 West Main Ramp. The fall of ground area is expected to be rehabilitated by Q3 2023 and the 2 West Main Ramp was rehabilitated in April 2023. Reef yield increased by 29% to 7.06g/t in the March quarter from 5.45g/t in the December quarter due to ore phasing and stockpile movements which led to Gold in Process (GIP) drawdown amounting to 605kg. The GIP drawdown was mainly due to poor ground conditions as detailed above rendering some stopes unavailable and the associated impact on long-hole stoping tonnes. Total underground tonnes processed decreased by 10% to 438kt in the March quarter from 487kt in the December quarter due to lower tonnes broken as explained above as well as intermittent fleet reliability. Surface tonnes processed increased by 21% to 304kt in the March quarter from 252kt in the December quarter in line with the business plan. Surface yield decreased by 50% from 0.2g/t in the December quarter to 0.1g/t in the March quarter due to the depletion of the higher-grade clean up surface material, which was processed in December 2022. Total development increased by 7% to 2,972m in the March quarter from 2,790m in the December quarter as fewer shifts were worked in the December quarter due to the planned maintenance shutdown. Secondary support installed increased by 7% to 2,649m in the March quarter from 2,471m in the December quarter in line with increased development and destress performance. Backfill increased by 1% to 98,675m3 in the March quarter from 98,070m3 in the December quarter. All-in cost decreased by 7% to R751,830/kg (US$1,317/oz) in the March quarter from R804,575/kg (US$1,415/oz) in the December quarter, mainly due to an increase in gold sold and lower capital expenditure, partially offset by higher cost of sales before amortisation and depreciation. The higher cost of sales before amortisation and depreciation is mainly due to a gold inventory charge to cost of R250m (US$14m) in the March quarter compared to a gold inventory credit to cost of R44m (US$3m) in the December quarter. Total capital expenditure decreased by 30% to R329m (US$19m) in the March quarter from R474m (US$27m) in the December quarter. Sustaining capital expenditure decreased by 12% to R329m (US$19m) in the March quarter from R376m (US$21m) in the December quarter, mainly due to lower spend on surface infrastructure and equipment. Non-sustaining capital expenditure decreased by 100% to R0m (US$0m) in the March quarter from R98m (US$6m) in the December quarter due to the inclusion of new mine development and related infrastructure in sustaining capital from 2023. 11
