GOLD FIELDS LIMITED - OPERATIONAL UPDATE FOR THE QUARTER ENDED 30 SEPTEMBER 2025 Gold Fields Limited Reg. 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) Operational update for the quarter ended 30 September 2025: - Attributable production 6% higher (QoQ) at 621koz - All-in sustaining costs (AISC) 10% lower (QoQ) at US$1,557/oz - All-in costs (AIC) 11% lower (QoQ) at US$1,835/oz JOHANNESBURG, 5 November 2025: Gold Fields Limited (NYSE & JSE: GFI) issues the following operational update for the quarter ended 30 September 2025. Detailed financial and operational results are provided on a six-monthly basis i.e. at the end of June and December. Statement by Mike Fraser, CEO Gold Fields delivered another solid performance in the third quarter, maintaining the positive momentum of the first half of the year. We continued to focus on our multi-year safety improvement plan and although we have had five consecutive quarters fatality-free, we had three serious injuries in the quarter, demonstrating the need for continued focus and effort in our safety journey. Group attributable production increased 6% quarter-on-quarter (QoQ) (+22% year-on-year (YoY)) while All-in costs (AIC) decreased by 11% QoQ (-4% YoY). All-in sustaining costs (AISC) declined by 10% QoQ and 8% YoY. Importantly, we remain on track to achieve our full-year production and cost guidance. Net debt decreased by US$696m during the quarter to US$791m at the end of September 2025 (net debt at 30 June 2025: US$1,487m), driven by strong cash generation, partially offset by the payment of the interim dividend of US$361m. Gold Fields remains in a robust financial position with a net debt to EBITDA ratio of 0.17x at the end of Q3 2025, compared to 0.37x in Q2 2025. Post the quarter-end, Gold Fields completed the acquisition of Gold Road Resources and paid US$1.45bn (A$2.23bn),net of cash received, the special dividend paid by Gold Road upon transaction close and the disposal of the Northern Star Resources shares that were acquired as part of the transaction. The purchase was funded using a fully underwritten bridge facility of US$2.3bn (A$3.48bn) that was executed on 15 July 2025. Taking into account the acquisition of Gold Road Resources and the disposal of the Northern Star Resources shares, we remain comfortably below a net debt: EBITDA ratio of 1.0x. On 26 September 2025, Gold Fields announced the monetisation of the Northern Star Resources shares acquired as part of the Gold Road Resources acquisition for total proceeds of A$1.1bn which were used to repay a portion of the bridge facility. Separately, Gold Fields also disposed of its 19.5% stake in Galiano Gold for a total consideration of C$151m. Safe, reliable, cost-effective operations Our operations continued to deliver strongly against plan during the quarter. Group attributable gold-equivalent production increased 6% QoQ to 621koz (Q2 2025: 585koz), and was 22% higher YoY (Q3 2024: 510koz). Further improvement is expected in Q4 2025 as the Salares Norte mine ramps up to steady-state production levels, and we consolidate 100% of the Gruyere mine post the acquisition of Gold Road Resources. Group AIC for Q3 2025 decreased by 11% QoQ to US$1 835/oz (Q2 2025: US$2,054/oz) primarily driven by higher gold

sales volumes and was 4% lower YoY (Q3 2024: US$1,909/oz), reflecting higher gold sold and lower capital expenditure. AISC for the quarter was US$1 557/oz, 10% lower QoQ (Q2 2025: US$1,739/oz) and 8% lower YoY (Q3 2024: US$1,694/oz),benefiting from increased gold production. The Australian assets performed in line with plan during Q3 2025. As in 2024, St Ives is expected to deliver a strong fourth quarter, although the increase from Q3 2025 will be less pronounced than in 2024. Following the completion of the Gold Road transaction on 14 October 2025, attributable production from Gruyere will be 100% for most of Q4 2025. On a like-for-like basis (50%), Gruyere's production is expected to increase in Q4 2025. Tarkwa's production increased 15% QoQ to 123koz in Q3 2025 (Q2 2025: 107koz), driven by higher feed grade resulting from an increased proportion of mined ore (vs lower-grade stockpile ore) in the processing mix. Production in Q2 2025 was affected by higher waste stripping, which led to a greater reliance on low-grade stockpiles. Tarkwa's production is expected to increase further in Q4 2025. South Deep had another steady performance in Q3 2025, producing 78koz and meeting its plan for the quarter. AIC were flat QoQ and only 3% higher YoY, illustrating the extent of the asset's leverage to increasing volumes. The team continues to make good progress in improving stope turnaround which is key to driving efficiency and realising incremental gains. Salares Norte continued to make good progress in its ramp-up. After producing 50koz eq in Q1 2025, the mine increased output by 46% QoQ to 73koz eq in Q2 2025 and by a further 53% QoQ to 112koz eq in Q3 2025. Production is expected to increase further in Q4 2025, positioning Salares Norte well to achieve its 2025 guidance of 325koz eq - 375koz eq, at an AISC of US$975/oz eq - US$1,125/oz eq. The mine achieved commercial levels of production during Q3 2025, and is making good progress towards steady-state levels of production, which is expected by year-end. 2026 is set to be the first full year of steady-state production, during which the mine is expected to produce 550koz eq - 580koz eq at an AISC of US$825/oz eq - US$875/oz eq. Have a positive social and environmental impact Gold Fields is in the process of finalising an internal mid-point review of its 2030 ESG targets, to ensure these targets remain context-based and aligned to our strategic aspirations for the business, and support the growth of our asset base. The preliminary outcomes of the review show that we have made good progress towards our targets with tangible benefits for the business and our stakeholders. The benchmarking work we have undertaken also shows that Gold Fields is either leading or aligned with our global peers. The outcomes of this review will be published with our FY 2025 results in February 2026. Construction of the St Ives renewables plant (comprising 35MW solar and 42MW wind capacity) continued during Q3 2025, with the project now 80% complete. All solar PV panels have been installed and electrical connections are underway. The components for the wind turbines have arrived in Australia and are currently being delivered to site. Once completed it is expected to deliver over 70% of the mine's electricity requirements and reduce its electricity costs to one third of the current costs. At Granny Smith, the 11MW solar plant commissioned in Q2 2025 operated at full capacity during Q3 2025. The site now has a total of 19MW of solar capacity and 9MW battery storage, with 20% of its electricity being generated from solar power in September. In August 2025, Gold Fields reported conformance with the Global Industry Standard on Tailings Management (GISTM), achieving over 95% compliance across all tailings storage facilities in the Group. Gold Fields remains committed to achieving 80% compliance prior to the transition of the Damang asset to the Government of Ghana in April 2026.

Growing the quality and value of our portfolio Gold Road transaction In May 2025, Gold Fields announced that it had entered into a binding Scheme Implementation Deed to acquire 100% of the issued and outstanding share capital of Gold Road Resources, thereby consolidating full ownership of the Gruyere mine. In September 2025, Gold Road Resources shareholders voted in favour of the transaction, and the Supreme Court of Western Australia subsequently approved the Scheme, which was then lodged with the Australian Securities and Investments Commission. As a result, all conditions were satisfied and the Scheme became effective on 26 September 2025. The Scheme was implemented on 14 October 2025, upon which Gold Road shareholders received a fixed cash consideration of A$2.08306 per share (representing A$2.52 per share) less a fully franked special dividend of A$0.43694 per share and a variable cash consideration of A$0.98117 per share linked to Gold Road's shareholding in Northern Star Resources. Owning 100% of Gruyere, along with the surrounding land package enables Gold Fields to optimise the life-of-mine plan and unlock additional value from the asset. Windfall progress During Q3 2025, the Windfall team made good progress in advancing the permitting approvals process for the project. Project execution readiness activities also continued to advance. The Final Investment Decision will be progressed, subject to approval of the Environmental Impact Assessment. Changes to Mineral Resources and Mineral Reserves prices As part of our annual process, we have revised our Mineral Resources and Mineral Reserves gold prices, increasing the Reserve gold price from US$1 500/oz to US$2 000/oz and the Resources gold price from US$1 725/oz to US$2 300/oz. The revision was mainly due to the higher gold consensus prices, gold price trends and inflation. While we have revised our gold price assumptions upward to reflect recent trends, we continue to apply a conservative approach to ensure Mineral Reserves remain resilient to potential price volatility. This balance recognises the strong price trends of recent years while safeguarding long-term value. A full portfolio Resources & Reserves update will be provided as part of the 2025 financial year-end reporting cycle in March 2026. The updated attributable Mineral Resources and Mineral Reserves for Tarkwa are outlined below in light of the upcoming mining lease renewal process. Tarkwa life-of-mine extension Tarkwa remains one of the cornerstone assets of the Gold Fields portfolio. Through proactive engagements with the Government of Ghana, we have initiated the process to renew the Tarkwa mining lease due to expire in April 2027. A key component of this process has been updating of Tarkwa's life-of-mine plan and the mine's declared Mineral Resources and Reserves. For 2025, managed Mineral Reserves have increased to 7.4 million ounces from 4.3 million ounces, while managed Mineral Resources (inclusive of Reserves) have grown to 11.2 million ounces from 8.9 million ounces. Gold Fields' attributable share, allowing for the Government of Ghana's 10% free-carry interest, represents 6.6 million ounces of Reserves (up from 3.8 million ounces) and 9.3 million ounces of Measured and Indicated, and 0.7 million ounces of Inferred Resources, inclusive of Reserves. This increase of approximately 70% in attributable Reserves is driven by the removal of key operational constraints, including a reduced Akontansi open pit stand-off distance from infrastructure and the higher Reserve gold price. A key focus for the team in the near to medium term is to optimise Tarkwa's operating costs to drive margin and cash generation and to further increase mineable inventory. Exploration update Greenfields exploration remains a core pillar of Gold Fields' growth strategy, aimed at building a long-term pipeline of high-quality, early-stage opportunities that will underpin production in 2035 and beyond. We continue to pursue

early-stage exposure to high-margin, low-capex gold systems through disciplined capital allocation across joint ventures, equity positions, and 100%-owned assets. In 2025, Gold Fields is advancing 19 active projects across four continents, testing more than 40 exploration targets. Exploration in Australia gained momentum during September 2025. The maiden drill rig has commenced at Edinburgh Park (Queensland), while airborne geochemical surveys have begun across West Tanami. In New South Wales, four East Lachlan targets have advanced to drill-ready status. The Gold Road integration is nearing completion, resulting in a 200% increase in Gold Fields' Australian greenfields landholding, and the addition of an experienced exploration team - enhancing our discovery capability heading into 2026. Momentum also continues to build across our landholding in Canada. A 38,000m greenfields drill programme commenced in July 2025, with strong progress at Windfall and surrounding regional targets. The Phoenix Joint Venture with Bonterra has now exceeded 70,000m of drilling. At Santa Cecilia in Chile, drilling through our joint venture with Torq Resources has confirmed a large, mineralised gold-copper porphyry system at Los Gemelos and Pircas. This marks an important milestone which validates the geological model and scale potential. Post quarter-end, Gold Fields proceeded with the second stage of the earn-in option for the Santa Cecilia project by contributing US$11m to cover all of the project costs, including a diamond drilling programme. In Peru, social permitting progressed well across the Moquegua and Leonidas projects, strengthening relationships with local communities and paving the way for initial drilling in 2026. Leadership changes After eight years at Gold Fields, Martin Preece retired on 31 August 2025. Following Martin's retirement, Francois Swanepoel, who was previously Chief Technical Officer (CTO), was appointed as Chief Operating Officer (COO). I would like to thank Martin for his valuable contribution and congratulate Francois on his new role. Jason Sander, who has extensive Technical and industry experience, was appointed as Acting Chief Technical Officer. FY2025 guidance remains unchanged Our priority for the remainder of 2025 is to ensure safe, reliable and cost-effective delivery against our production guidance for the year. Gold Fields remains on track to meet the original production and cost guidance provided in February 2025. Attributable gold-equivalent production is expected to be in the upper end of the guidance range of 2.250Moz - 2.450Moz. AISC are expected to be between US$1,500/oz - and US$1,650/oz, and AIC are expected to be between US$1,780/oz - US$1,930/oz.

The increase was driven by a 17% increase in tonnes milled which was partially offset by a 9% decrease in yield as a result of a lower proportion of ore mined from the higher-grade Stage 4 of the Gruyere pit. AIC decreased by 3% to A$2,951/oz (US$1,924oz) in the September quarter from A$3,027/oz (US$1,937oz) in the June quarter due to higher gold sales partially offset by increased capital expenditure. Total capital expenditure (on a 50% basis) increased by 5% to A$51m (US$33m) in the September quarter compared to A$49m (US$31m) in the June quarter, with increased pre-strip mining at stage 6 of the Gruyere pit. September 2025 quarter compared with the September 2024 quarter The higher gold production in the September 2025 quarter when compared to the September 2024 quarter was primarily due to lower tonnes milled in the September 2024 quarter, which was a result of reduced availability of fresh rock from the Gruyere pit as mining activities focused on catching up the pre-strip shortfall following the major rainfall event in early 2024.

Overall material movement was higher in the September 2025 quarter as the mining contractor continued to build efficiency and capability to achieve the required output. The 1% higher AIC in the September 2025 quarter compared to the September 2024 quarter was due to higher capital expenditure as a result of increased capital waste tonnes mined combined with higher contractor mining costs, partially offset by higher gold sales. Higher capital expenditure in the September 2025 quarter was mainly due to increased capital waste mining.

AIC decreased by 10% to A$2,121/oz (US$1,384/oz) in the September quarter from A$2,346/oz (US$1,506/oz) in the June quarter due to higher gold sales partially offset by higher capital expenditure. Total capital expenditure increased by 14% to A$41m (US$27m) in the September quarter from A$36m (US$23m) in the June quarter. During the September quarter A$4m (US$3m) was spent on a new fresh air intake system to support the Z135 and Z150 extraction levels. September 2025 quarter compared with the September 2024 quarter The lower gold production in the September 2025 quarter, when compared to the September 2024 quarter, was mainly due to

lower tonnes milled. Higher AIC compared to the September 2024 quarter was mainly due to increased capital expenditure and higher cost of sales before amortisation and depreciation, partially offset by higher gold sold. Lower capital expenditure in the September 2024 quarter was due to lower development activity in the Z135 area, arising from ventilation restrictions and increased ground support requirements.

Increased capital expenditure and cost of sales before amortisation and depreciation, partially offset by higher gold sold, resulted in an 11% increase in AIC to A$3,562/oz (US$2,317/oz) in the September quarter from A$3,217/oz (US$2,063/oz) in the June quarter. The increase in cost of sales before amortisation and depreciation was mainly due to higher maintenance costs as a result of the plant shutdowns and increased mining contractor rates at the underground operations. Total capital expenditure increased by 41% to A$127m (US$83m) in the September quarter from $91m (US$58m) in the June quarter. During the September quarter A$69m (US$45m) was spent on the Renewables Power Project (June quarter - A$37m/US$24m). September 2025 quarter compared with the September 2024 quarter Gold production was higher in the September 2025 quarter compared to the September 2024 quarter mainly due to higher tonnes milled. AIC was higher compared to the September 2024 quarter, primarily due to increased capital expenditure, as well as higher commodity input prices and employee and contractor costs. These increases were partially offset by higher gold sales achieved in the September 2025 quarter. The increased capital expenditure compared to the September 2024 quarter reflects increased spend on the Renewables Power Project.

Higher gold sold and lower capital expenditure resulted in a 19% decrease in AIC to A$2,541/oz (US$1,654/oz) in the September quarter from A$3,154/oz (US$2,018/oz) in the June quarter. Total capital expenditure decreased by 16% to A$35m (US$23m) in the September quarter from A$42m (US$27m) in the June quarter, following decreased mine development in the lower Kath area of the Waroonga complex. September 2025 quarter compared with the September 2024 quarter Gold production in the September 2025 quarter was 2% higher than the September 2024 quarter. The higher AIC in the September 2025 quarter compared to the September 2024 quarter was due to lower capital expenditure in the September 2024 quarter, partially offset by increased gold sold in the September 2025 quarter. The lower capital expenditure in September 2024 was due to decreased development at Waroonga following unfavourable ground conditions in the lower levels of the Kath ore body.

On 31 August 2025, the operation achieved commercial levels of production, following the sustained improvement of the plant throughput and metallurgical recoveries, marking a key milestone in the ramp-up phase. AIC decreased by 56% to US$982/oz in the September quarter from US$2,215/oz in the June quarter due to higher gold sold and lower capital expenditure.

Total capital expenditure decreased by 41% to US$68m in the September quarter from US$116m in the June quarter, mainly due to the higher expenditure related to the additional work identified at the plant in preparation for winter conditions. September 2025 quarter compared with September 2024 quarter Gold-equivalent production in the September 2025 quarter increased significantly when compared to the September 2024 quarter as the September 2024 quarter was used to set the plant up for a safe and sustainable restart and ramp-up following the impact of the 2024 winter on ramp-up activities. The higher capital expenditure in the September 2024 quarter related to ramp-up capital and additional capital due to the impact of the 2024 winter on the processing facility.

September 2025 quarter compared with the June 2025 quarter Gold-equivalent production decreased by 20% to 41,400oz in the September quarter from 51,800oz in the June quarter, mainly due to lower tonnes milled as well as lower gold and copper grades processed, in line with the mine sequence. AIC per gold ounce sold decreased by 22% to US$475/oz in the September quarter from US$606/oz in the June quarter, mainly due to lower cost of sales before amortisation and depreciation and higher by-product credits to cost, partially offset by lower gold sales and higher capital expenditure. Total capital expenditure increased by 234% to US$12m in the September quarter from US$4m in the June quarter, mainly due to an increase in construction activities related to the in-pit tailings deposition system. September 2025 quarter compared with the September 2024 quarter Gold-equivalent production was similar in the September 2025 quarter compared to the September 2024 quarter. AIC per gold ounce sold decreased by 5% in the September 2025 quarter mainly due to higher by-product credits to cost, and higher gold sales, partially offset by higher capital expenditure. Total capital expenditure increased by 139% in the September 2025 quarter, mainly due to the in-pit tailings deposition system construction.
