Highlights • Attributable gold-equivalent production of 1.267Moz is up 12% year-on-year (YoY) and on track to meet the upper end of full-year guidance • Salares Norte production is up 173% as the mine reached steady-state and is well positioned to outperform full-year guidance • Adjusted free cash flow of US$2,225 million, is up 134%, driven by higher sales volumes, a supportive gold price and Salares Norte's transition to steady-state • Headline earnings of US$1,855 million (208 US cents per share) are up 81% YoY • Total allocated to additional shareholder returns increased to a cumulative US$1.25 billion, from US$750 million in February 2026; US$300 million in share buy-backs completed to date • Interim dividend of 1,625 SA cents per share declared, up 132% YoY • Net debt/adjusted Earnings Before Interest, Taxes, Depreciation, and Amortisation (EBITDA) of 0.06x, down from 0.37x as at the end H1 2025, reflecting continued balance sheet strength • Zero fatalities or serious injuries Statement by Mike Fraser, CEO Gold Fields delivered a strong first half as sales volumes rose by 18% to 1.269Moz, supported by a higher average realised gold price of US$4,678/oz, which resulted in adjusted free cash flow more than doubling to US$2,225 million from US$925 million in H1 2025. This gave us the platform to strengthen our balance sheet further, continue investing in the long-term growth and resilience of our business, while delivering upper quartile shareholder returns. Strong production led by Salares Norte and Granny Smith Operational momentum built in 2025 continued through the half, with Group attributable production increasing 12% YoY to 1.267Moz, keeping the Group firmly on track to deliver to the upper end of full-year guidance. Salares Norte was a key contributor as the mine reached steady-state production and delivered a 173% increase in gold- equivalent production to 337koz. Granny Smith also delivered a strong first half, with production up 10% on record haulage fleet availability and autonomous truck performance. South Deep continued to demonstrate incremental improvement in stope turnover and mining productivity while Gruyere, Agnew and Tarkwa showed encouraging signs of improvement in the second quarter as recovery plans gained traction. Financial strength translating into shareholder value Higher volumes and a stronger gold price drove a step-change in financial performance. Group headline earnings increased 81% to US$1,855 million and adjusted free cash flow before discretionary investments rose by 101% to US$2,510 million (H1 2025: US$1,251 million), as higher cash flows from operating activities were partially offset by higher sustaining capital expenditure. The Group invested US$609 million (US$496/oz) in sustaining capital to maintain the quality and performance of its asset base. Net debt to adjusted EBITDA fell to 0.06 times, from 0.37 times a year earlier, reflecting the strength and resilience of the balance sheet. This performance is underpinning higher returns to shareholders. 61% of adjusted free cash flow was paid to shareholders as dividends in the period and we stepped up our share buy-back programme, completing share repurchases of US$300 million between March and July 2026. Today, we are allocating a further US$500 million to additional shareholder returns, lifting the additional returns programme announced in November 2025 to a cumulative US$1.25 billion1 to be delivered through a combination of special dividends and targeted share buy-backs. Of the US$1.25 billion programme, US$253 million was paid out as a special dividend in February 2026 while US$300 million has been delivered through share buy-backs.

A gross interim dividend of 1,625 SA cents per share is payable on 14 September 2026. In line with the Group's policy of paying out 35% of free cash flow before discretionary investments, the Board today declares an interim dividend of 1,625 SA cents per share, up 132% from the interim dividend of 700 SA cents per share declared for H1 2025. These results demonstrate the improving quality and resilience of our business, and our ability to translate a supportive gold market into value for shareholders through disciplined operational execution and capital allocation. 1Subject to applicable legal, regulatory and board approval requirements Unaudited interim results for the six months ended 30 June 2026 Gold Fields Limited Reg. No. 1968/004880/06 Incorporated in the Republic of South Africa JSE, NYSE, DIFX Share Code: GFI ISIN Code: ZAE000018123 Safety, strategy and the growth pipeline Gold Fields recorded no fatalities or serious injuries across the Group in H1 2026, continuing the positive trajectory of the Safety Improvement Plan launched in 2024. We remain firmly focused on ensuring that everyone leaves work safe and well each day. The Group continued to advance its three-pillar strategy, including progress towards Final Investment Decision (FID) at the Windfall Project in Canada, where a key milestone was reached with the signing of an Impact Benefit Agreement (IBA) with the Cree First Nation. The IBA reflects our commitment to building strong partnerships with our host communities while providing greater certainty for the project’s development. As we await approval of the Environmental Impact Assessment (EIA) for Windfall, we are advancing project engineering, optimising execution planning and progressing operational readiness which will significantly de-risk the project ahead FID. Project capital is expected to be at the upper end of the US$1.7 billion – US$1.9 billion (real 2025 terms) guidance provided at our Capital Markets Day in November 2025. The high-quality Windfall Project represents the next growth frontier for Gold Fields and once developed, will become a cornerstone asset within our portfolio. We will provide a further update once the EIA is approved and FID is confirmed. Mitigating external cost impacts Group unit costs increased during the period, primarily due to external factors – including higher gold-price linked royalties, stronger producer- country currencies, and higher input costs. All-in sustaining cost (AISC) increased 13% to US$1,893/oz and total all-in costs (AIC) increased 9% to US$2,125/oz, with these external factors partly offset by higher gold sales and the cost-diluting contribution from Salares Norte. A sector- competitive underlying cash cost of US$1,180/oz reflects the quality and resilience of the portfolio, supporting strong cash generation, disciplined reinvestment in our assets and growth projects, and the delivery of superior long-term returns to shareholders. Transforming our business We have commenced a Group-wide transformation programme aimed at improving productivity, cost competitiveness and organisational resilience. The programme combines value delivery initiatives across mining, processing, asset management, supply chain and support functions with the implementation of common systems and standard processes within a consistent operating model across the Group. Opportunities include improving fleet performance, increasing plant throughput and recovery, optimising maintenance and inventory practices, as well as simplifying support functions. Following the commencement of baseline establishment, benchmarking and opportunity identification, we continue to identify and prioritise opportunities while progressively commencing implementation and value delivery across selected workstreams. Through 2027 and beyond, the programme will scale delivery across the Group, while embedding the systems, processes and management disciplines required to sustain performance improvements. Delivery by operation Gruyere delivered attributable production of 120koz in H1 2026, a decrease of 17% YoY (H1 2025: 144koz), primarily reflecting lower mining productivity, which resulted in production being below plan. Performance improved during Q2 2026, with production increasing by 25% (13koz) quarter-on-quarter (QoQ) as recovery initiatives began to gain traction. Improvement actions include upgraded pit dewatering infrastructure, the deployment of two new 600t excavators and reduced contract turnover rate which is driving improved operational momentum. While the benefits are expected to build progressively over time, the recovery is constrained by interface challenges between stages 4 and 5 of the pit. The mine is expecting to deliver target run rates by the end of Q3 2026, however remains at risk of not recovering the H1 2026 shortfall. Granny Smith delivered a strong first-half performance, producing 147koz in H1 2026 – 10% higher YoY (H1 2025: 134koz). The improvement was driven by higher haulage fleet availability, record autonomous truck performance and the successful re-establishment of mining in the Z135 East area following ground support upgrades. Disciplined execution of the development plan into the priority Z135 West mining areas further strengthened operational performance and supports the asset’s production outlook. St Ives produced 170koz gold-equivalent in H1 2026 (H1 2025: 185koz), 8% lower than H1 2025 but 3% higher in Q2 2026 compared to Q1 2026. Production was constrained by ore supply challenges at the Invincible underground mine following an approximately seven-month restriction on the primary ventilation system due to salt build up in a vent raise, which limited development and reduced broken-stock availability. Production was further impacted by the decision to bring the mill reline shutdown forward into Q2 2026. These impacts were offset by strong production from the open pits and consistent performance from Hamlet. Despite the lower production in H1 2026, St Ives is expected to deliver on planned production profile for the full year with a stronger H2 2026 expected. Agnew produced 103koz in H1 2026, 15% lower than H1 2025 (122koz). Performance improved during Q2 2026, with production increasing by 12koz QoQ as operational stability improved. This is a result of the rebuilding of the Waroonga underground production profile following seismic rehabilitation in Q1 2026, together with continued improvements in paste-fill reliability and the disciplined execution of the recovery plan. Tarkwa produced 192koz in H1 2026, 18% lower than H1 2025 (233koz), reflecting lower mill feed grades, grade reconciliation issues in a section of the underlap pit and the impact of adverse weather on load, haul and drilling activities. Performance improved during Q2 2026 as rainfall eased, supporting better mining conditions and continued progress of the recovery plan. Our focus remains on improving drill rig reliability and productivity, increasing blasted ore stocks and bringing additional drilling capacity online to strengthen ore availability in H2 2026. While the recovery is gaining traction, Tarkwa is at risk of not recovering the H1 2026 shortfall and therefore not meeting full- year guidance. South Deep delivered a solid first-half performance, with attributable gold production of 151koz in H1 2026, down 1% from H1 2025 (153koz). Performance improved during Q2 2026 and in line with the plan, supported by stronger destress mining, improved development rates, stable grades, improved long-hole stoping, and enhancements to water management, ventilation and backfill infrastructure. A five-year wage agreement was signed post-period end which provides a solid base for stability. Salares Norte delivered an outstanding first-half performance, with production increasing 173% to 337koz gold-equivalent (H1 2025: 124koz gold-equivalent) as the operation successfully completed its ramp-up to steady-state production. This was supported by strong plant availability through the onset of winter, resulting in higher-than-planned throughput and better-than-budgeted reconciled head grades. The operation remains well positioned to outperform its annual guidance. Having a positive impact on our communities and the environment Our ability to create long-term value depends on the success of our host communities and responsible environmental stewardship. Guided by our 2035 commitments, we continued to invest in programmes and partnerships that create shared value, strengthen local communities and support positive social and environmental outcomes. Host community value creation During H1 2026, the Group delivered approximately US$4.96 billion in stakeholder value, including US$941 million to host communities, through employment, procurement, taxes, royalties and community investment, reflecting our continued contribution to local economies. Our Group Legacy Programme continues to advance our commitment to creating enduring value beyond mining. During H1 2026, we progressed the development and implementation of multi-year programmes across Australia, South Africa, Ghana, Chile and Peru. Distributions from the Thusano Trust continue to progress, with 88% of the total proceeds of US$440.5 million (R7.37 billion) paid to beneficiaries in South Africa. Mitigating climate change Renewable electricity continued to support our decarbonisation efforts, contributing 181 gigawatt-hours (GWh), which comprised 17.4% of Group electricity consumption in H1 2026. Agnew remained the Group’s leading renewable energy operation, with renewable electricity accounting for 43% of its power supply. Scope 1 and 2 emissions were 4% lower than in H1 2025, with cumulative emissions abatement from renewable electricity in 2025 forecast to reach 101ktCO₂e from a 2022 baseline. 2 GOLD FIELDS H1 Results 2026 Construction of the St Ives Renewables Project is substantially complete, with all seven wind turbines, powerline infrastructure and substation works constructed and ready for connection. Commissioning has been delayed to H2 2026 pending completion of the wind turbine verification requirements and finalisation of grid connection and operating agreements. Preventing serious environmental harm There is a continued focus on preventing serious environmental harm through strong incident prevention, permitting discipline, tailings oversight and improved environmental risk management. During Q2 2026, we recorded nine level 2 environmental incidents and no significant tailings incidents. Environmental standard gap assessments and site-specific implementation roadmaps continued to strengthen critical control management and second-line assurance. Responsible tailings management is paramount and the Group continued to maintain conformance with the Global Industry Standard on Tailings Management (GISTM). During H1 2026, we advanced a portfolio of initiatives to continually improve tailings performance, unlock future storage capacity and enhance operational flexibility. Key milestones included a successful mud farming trial at Cerro Corona, which will accelerate consolidation of the upper tailings layers and increase tailings density, improving storage efficiency and unlock additional capacity within the existing facility. Additionally, we are developing a commingling trial at Tarkwa, which involves blending tailings with waste rock to reduce footprint, capital and technical risk and a filtration plant design for Windfall. Update on the renewal of the Tarkwa mining leases Following our early submission of an application for the renewal of the Tarkwa mining leases in November 2025, at the request of the Government of Ghana in April 2025, Gold Fields continued to engage with the Government of Ghana to progress the Tarkwa lease renewals, which expire in April 2027. In July 2026, we submitted a comprehensive commercial proposal to the Government of Ghana to support the renewal of the leases and long-term sustainability of Tarkwa. Our proposal is underpinned by a significant programme of investment over the Tarkwa life of mine, while also seeking to deepen our partnership with Ghana through increased value-sharing that delivers meaningful national benefit, strengthens the country’s fiscal position and drives long-term social development. Components of our proposal include expanded community investment, increasing support to local businesses, further investment in local skills development and enhanced long-term socio-economic value creation. We are still awaiting a formal response to our proposal from the Government of Ghana, and, at this stage, have no confirmed timeframe for this response or for the conclusion of our negotiations regarding the lease renewals. As such, there remains uncertainty as to the timing, outcome, and terms of any negotiated agreement to renew the Tarkwa leases. An adverse outcome of the renewal process would have a material and adverse impact on Gold Fields. We are considering all options available to us with respect to the renewal of the Tarkwa leases and our Development Agreement (DA), including pursuing our legal rights under the leases, DA, and at law, if required. We remain committed to Tarkwa and our long-term contribution in Ghana, where we have operated for over 30 years. Subject to the outcome of the renewal process, we believe that Gold Fields remains well positioned to continue investing in and operating the Tarkwa mine, including exploring opportunities to extend the mine life beyond the current known reserves, creating lasting value for both Ghana and Gold Fields. Growing the quality of our portfolio Progressing the Windfall Project Windfall is one of Canada's highest-grade development-stage gold deposits. With considerable growth prospects along strike and down plunge, the project is expected to provide a long-life, low-cost production platform. While Windfall is the anchor asset, opportunity extends well beyond the current mine plan. Having secured a highly prospective land package across the district, Gold Fields is accelerating exploration across a target-rich pipeline with the objective of progressively expanding the scale, scope and longevity of Windfall through new discoveries and the addition of high-margin ounces that can leverage the infrastructure already being developed. Following the update provided in the Trading Statement, issued on 11 August 2026, we continue to await a recommendation for the issuance of the EIA from the Environmental and Social Impact Review Committee (COMEX) of Québec. Based on engagements with both the Government of Québec and the Cree First Nation Government, EIA approval is now expected in H2 2026, after which it is expected that the project will progress to FID. During this period, the focus remains on derisking the project ahead of final approval. We are adjusting on-site activities and the project development schedule to optimise costs while maintaining flexibility to progress FID and development after the EIA approval is received. Gold Fields will provide a further update once the EIA is approved and FID is confirmed, together with an updated project execution schedule and capital estimate. Windfall is a world-class project with robust economics. Once developed, we expect it to become a cornerstone asset within the Gold Fields portfolio. Brownfields Brownfields exploration remains a core pillar of Gold Fields' capital allocation strategy, supporting reserve replacement, mine-life extension and capital-efficient growth from existing infrastructure. During H1 2026, the Group invested US$56 million in brownfields exploration, completing 148km of drilling across its operations. Key achievements include the resumption of surface drilling at South Deep to infill the South of Wrench (SOW) area, where the first hole has intersected the orebody timeously and as expected, with additional rigs planned to accelerate the programme. At St Ives, strong drilling results were returned from Santa Ana, Achilles and the Invincible complex, supporting future resource growth and production flexibility. Further improving the quality of our portfolio During H1 2026, we continued to improve the quality of our portfolio by disposing of non-core investments, generating approximately US$182 million in cash proceeds. This included the completing of the previously announced US$167 million sale of a portfolio of royalties and related interests to OR Royalties. The remaining proceeds were generated through the disposal of selected non-core listed investments, reflecting our disciplined approach to portfolio management and capital allocation. Greenfields exploration continued to progress during H1 2026, with new drilling campaigns advancing, the exploration portfolio expanding and a pipeline of opportunities being developed to support long-term growth beyond 2035. Our strategic investment in Founders Metals continues to provide exposure to the emerging Antino gold district in Suriname, where exploration success and district consolidation are strengthening the project’s long-term potential. Following the period end, we agreed to invest C$77 million to increase our interest in Founder Metals to approximately 19.9%, supporting Founders’ consolidation of 100% ownership of Antino and continued exploration across its highly prospective 102,360-hectare land package. In Australia, we expanded our portfolio through the Everleigh Joint Venture with Iceni Gold, securing a staged earn-in to a prospective greenfields project in Western Australia with district-scale potential. We also established a 5.33% strategic equity interest in Augustus Minerals, providing exposure to two drill-ready exploration opportunities. Across the former Gold Road exploration portfolio, we continued to rationalise non-core assets, unlock value through strategic transactions and advance priority projects toward drilling. During the period, we commenced drilling at the Wayra Project in southern Peru while drilling continued at the Villa Tati Project in Chile. In Australia, drilling progressed adjacent to Newmont's Cadia Valley operations, with further drilling planned at the East Lachlan and Edinburgh Park joint ventures during the second half of the year. In Canada, the C$24.5 million regional exploration programme at Windfall continued. Land access, permitting and field activities progressed during the period, positioning the team for the next phase of drilling across Gold Fields' 2,500km² land package. 3 GOLD FIELDS H1 Results 2026 Board and Executive Committee appointments John MacKenzie was appointed Non-executive Chair of the Board following the Annual General Meeting on 21 May 2026. John brings extensive international executive and non-executive leadership experience across the natural resources sector. We further strengthened our executive leadership team with the appointment of Francois Hardy as Chief Technical Officer, effective 1 August 2026. Francois has more than 30 years of international mining experience across operations, technical services and project development, with a strong track record of delivering safe and reliable, operational performance. We announce the appointment of Andiswa Ndoni as interim company secretary of the Company. Andiswa will take over from Anré Weststrate with effect from 1 September 2026, as part of ongoing restructuring of the Group governance, compliance, and ethics functions. Shareholders will be advised as to the permanent appointment of the company secretary in due course. Andiswa is an admitted attorney (LLB) with over 31 years of experience in the legal profession, spanning corporate and commercial law as well as corporate governance and company secretarial roles. The Board is satisfied that Andiswa has the requisite knowledge and experience to fulfil the role of interim company secretary of the Company and confirms that the relevant fit and proper assessment has been conducted. We would like to thank Anré for her contribution to the Group during her term of office and wish her well. 2026 guidance Gold Fields enters the second half of 2026 with strong operational and financial momentum, a materially strengthened balance sheet, and continued visibility on our growth pipeline, including advancing Windfall towards FID and ongoing engagement with the Government of Ghana on the Tarkwa lease renewal. We remain on track to meet the production and cost guidance. Attributable gold-equivalent production for 2026 is expected to be at the upper end of the guidance range of 2.4 and 2.6Moz. Guidance is supported by continued outperformance expected at Salares Norte in H2 2026. Recovery plans are being implemented at Gruyere and Tarkwa, however, despite improved performance in Q2 2026 and expected improvements in H2 2026, both assets remain at risk of delivering below their full-year guidance. In line with the guidance provided in February 2026, AISC and AIC are expected to be between US$1,800 and US$2,000/oz, and US$2,075 and US$2,300/oz respectively. AIC is expected to be towards the lower end of the range, as Group capital expenditure is now expected to be between US$1,600 million and US$1,800 million, compared to prior guidance of US$1,900 million to US$2,100 million. The reduction primarily reflects reclassifying of certain Windfall expenditure from capital expenditure to exploration expense. Accordingly, while capital expenditure is expected to decrease, a portion of the reduction will be offset by higher growth exploration expenditure. Sustaining capital expenditure guidance remains unchanged at US$1,300 million to US$1,400 million. We remain focused on translating the momentum gained into sustained, disciplined value creation for shareholders. The above guidance is subject to the forward-looking statements on page 58 of this announcement. Mike Fraser Chief Executive Officer 25 August 2026 4 GOLD FIELDS H1 Results 2026

Cost of sales before amortisation and depreciation Cost of sales before amortisation and depreciation increased by 52% from US$1,108m for the six months ended 30 June 2025 to US$1,679m for the six months ended 30 June 2026 mainly due to the increase in production at Salares Norte, inflationary pressures on commodity inputs and employee and contractor costs and a charge to GIP of US$69m in 2026 as opposed to a credit of US$58m in 2025. Amortisation and depreciation Amortisation and depreciation for the Group increased by 74% from US$361m for the six months ended 30 June 2025 to US$629m for the six months ended 30 June 2026 mainly due to Salares Norte achieving commercial levels of production in 2025 and amortising in full for six months in 2026. Investment income Investment income increased by 79% from US$19m for the six months ended 30 June 2025 to US$34m for the six months ended 30 June 2026 due to higher cash and cash equivalents. Finance expense Finance expense for the Group increased by 162% from US$42m for the six months ended 30 June 2025 to US$110m for the six months ended 30 June 2026 due to higher borrowings and cessation of capitalisation of interest for Salares Norte during the six months ended 30 June 2026. Interest expense on borrowings of US$79m, interest on lease liability of US$16m and rehabilitation interest of US$15m for the six months ended 30 June 2026 compared with interest expense on borrowings of US$69m, interest on lease liability of US$12m and rehabilitation interest of US$13m, partially offset by interest capitalised of US$53m for the six months ended 30 June 2025 Share of results of equity-accounted investees after taxation The share of results of equity-accounted investees’ losses after taxation of US$1m for the six months ended 30 June 2025 compared to a profit of US$1m for the six months ended 30 June 2026, both relating to equity-accounted results from Lunnon. (Loss)/gain on foreign exchange The gain of US$34m for the six months ended 30 June 2025 compared to a loss of US$40m for the six months ended 30 June 2026 and both related to the conversion of offshore cash holdings and borrowings into their functional currencies. Share-based payments Share-based payments for the Group increased by 122% from US$9m for the six months ended 30 June 2025 to US$20m for the six months ended 30 June 2026 mainly due to higher forecast vesting percentages of share-based payments. Long-term incentive plan The long-term incentive plan expense decreased by 60% from US$15m for the six months ended 30 June 2025 to US$6m for the six months ended 30 June 2026 due to the phasing out of the scheme. Other costs, net Other costs for the Group decreased by 69% from US$16m for the six months ended 30 June 2025 to US$5m for the six months ended 30 June 2026. Exploration expense Exploration expense increased by 35% from US$133m for the six months ended 30 June 2025 to US$179m for the six months ended 30 June 2026 due to higher spend at the Windfall project in Canada. Non-recurring items Non-recurring items increased from US$5m for the six months ended 30 June 2025 to US$60m for the six months ended 30 June 2026. Royalties Government royalties for the Group increased by 56% from US$89m for the six months ended 30 June 2025 to US$139m for the six months ended 30 June 2026 in line with the higher revenue. Mining and income taxation The taxation charge for the Group increased by 110% from US$565m for the six months ended 30 June 2025 to US$1,184m for the six months ended 30 June 2026 in line with the higher profit before taxation.

Discontinued operations (Loss)/profit from discontinued operations The Damang mine was formally transferred to the Government of Ghana on 18 April 2026 following the expiry of the 12-month mining lease granted to Gold Fields in April 2025. For accounting purposes, Damang is considered an abandoned asset and has been classified as a discontinued operation. Profit from discontinued operations of US$29m for the six months ended 30 June 2025 compared to a loss of US$19m for the six months ended 30 June 2026. Statement of cash flow Cash flow from operating activities Cash inflow from operating activities increased by 37% from US$1,306m for the six months ended 30 June 2025 to US$1,793m for the six months ended 30 June 2026. The increase was mainly due to a higher profit before royalties and taxation partially offset by higher taxation and royalties paid. Dividends paid increased by 239% from US$376m for the six months ended 30 June 2025 to US$1,274m for the six months ended 30 June 2026. The dividend paid of US$1,274m for the six months ended 30 June 2026 comprised dividends paid to owners of the parent of US$1,234m related to the 2025 final dividend and dividends paid to non-controlling interest holders of US$40m.

Cash flow from investing activities Cash outflow from investing activities decreased by 11% from US$656m for the six months ended 30 June 2025 to US$586m for the six months ended 30 June 2026. Capital expenditure Capital expenditure increased by 6% from US$667m for the six months ended 30 June 2025 to US$709m for the six months ended 30 June 2026. The capital expenditure of US$709m for the six months ended 30 June 2026 comprised of sustaining capital expenditure of US$609m (H1 2025:US$505m) and non-sustaining capital expenditure of US$100m (H1 2025: US$162m). The increase in sustaining capital is mainly due to higher spend at Gruyere and Tarkwa. The decrease in non-sustaining capital is due to a lower spend at Salares Norte following completion of project-related construction activities. 7 GOLD FIELDS H1 Results 2026 Purchase of investments Purchase of investments decreased by 13% from US$32m for the six months ended 30 June 2025 to US$36m for the six months ended 30 June 2026.

Net cash generated Net cash generated for the Group increased by 169% from US$159m for the six months ended 30 June 2025 to US$427m for the six months ended 30 June 2026. After accounting for a negative translation adjustment of US$9m on non-US Dollar cash balances, the cash inflow for the six months ended 30 June 2025 was US$418m. The cash balance at 30 June 2026 of US$2,197m compared with US$1,067m at 30 June 2025. Adjusted free cash flow Adjusted free cash increased by 134% from US$952m for the six months ended 30 June 2025 to US$2,225m for the six months ended 30 June 2026 due to higher cash flows from operating activities partially offset by higher capital expenditure. Adjusted free cash flow is calculated as follows: Six months ended US$’m June 2026 June 2025 Net cash from operations 3,107.8 1,625.8 South Deep BEE dividends (0.4) (0.7) Capital expenditure – additions (709.1) (667.4) Capital expenditure – working capital — (4.1) Proceeds on disposal of property, plant and equipment 0.2 1.5 Contributions to environmental trust funds (10.8) (4.4) Contributions to secured cash deposits (18.7) (11.9) Payment of lease liability (66.2) (47.5) Cash utilised/generated by discontinued operation (77.5) 60.4 Adjusted free cash flow 2,225.3 951.7 Adjusted free cash flow is calculated as cash flow from operating activities less net capital expenditure, environmental payments, lease payments and redemption of Asanko preference shares. Statement of financial position Net debt decreased by 71% from US$1,487m at 30 June 2025 to US$437m at 30 June 2026. Net debt excluding lease liabilities of US$1,055m at 30 June 2025 compared to net cash of US$22m at 30 June 2026. Net debt is defined by the Group as total borrowings and lease liabilities less cash and cash equivalents. Net debt/adjusted EBITDA The net debt/adjusted EBITDA ratio of 0.06 at 30 June 2026 compared with 0.37 at 30 June 2025. The net debt/adjusted EBITDA ratio of 0.06 at 30 June 2026 is based on net debt of US$437m and adjusted EBITDA of US$7,604m. The net debt/adjusted EBITDA ratio of 0.37 at 30 June 2025 is based on net debt of US$1,487m and adjusted EBITDA of US$3,977m. Adjusted EBITDA Adjusted EBITDA for calculating net debt/adjusted EBITDA is based on the profit for the 12 months ended 30 June 2026 and 30 June 2025 and is determined as follows in US$ million: US$’m June 2026 June 2025 Revenue 11,320 6,555 Cost of sales before amortisation and depreciation (3,328) (2,340) Exploration and project costs (343) (200) Other costs* (45) (38) 7,604 3,977 * Other costs include other non-mine-based costs Adjusted EBITDA is defined by the Group as profit or loss for the year adjusted for interest, taxation, amortisation and depreciation and certain other non-operating costs All-in sustaining and total all-in cost Year-on-year The Group AISC (including Damang) increased by 13% from US$1,682/oz for the six months ended 30 June 2025 to US$1,893/oz for the six months ended 30 June 2026 mainly due to higher cost of sales before amortisation and depreciation, higher sustaining capital expenditure and higher royalties, partially offset by higher gold sold and higher by- product credits to cost. The higher sustaining capital expenditure was mainly at the Australian operations and Tarkwa, partially offset by lower sustaining capital expenditure at Salares Norte. Total AIC (including Damang) increased by 9% from US$1,957oz for the six months ended 30 June 2025 to US$2,125oz for the six months ended 30 June 2026 mainly due to the same reasons as above for AISC, partially offset by lower non-sustaining capital expenditure.

Pre-September 2025 financial results were reported on a 50% basis. Gold production decreased by 17% to 119,700oz for H1 2026 from 144,200oz for H1 2025. H1 2026 production was affected by a significant rainfall event, which disrupted ex-pit production for approximately four weeks. AIC increased by 48% to A$4,394/oz (US$3,088/oz) in H1 2026 from A$2,961/oz (US$1,878/oz) in H1 2025. The increase reflects higher production costs due to inflationary pressures on commodity inputs and employee and contractor costs, increased capital expenditure, and lower gold sales following the ounce production shortfall. Total capital expenditure increased by 187% to A$252m (US$177m) in H1 2026 from A$88m (US$56m) in H1 2025, reflecting the recognition of Gruyere's financial results at 100% following the acquisition. The increase also included A$31m (US$22m) of additional pre-strip mining expenditure at Stage 6 of the Gruyere pit, together with A$46m (US$32m) for the purchase of three new excavators. Adjusted pre-tax free cash flow for Gruyere increased by 85% to A$249m (US$175m) in H1 2026 from A$135m (US$86m) in H1 2025.

This performance was achieved despite a 9% reduction in underground grade offset by a 6% increase in reef tonnes. The lower grade was largely a consequence of the full implementation of the new mining sequence, which affected the mix of mining areas and grade profile during the period. The transition to the new mining sequence also resulted in a 15% reduction in total development metres, which in turn contributed to an 11% decrease in secondary support installation compared with the first half of 2025. Surface tonnes milled decreased by 13%, from 739kt in the first half of 2025 to 639kt in the first half of 2026, primarily due to scheduled maintenance associated with the thickened tailings project. The project is aimed at reducing the volume of water reporting to the tailings storage facility and forms part of ongoing efforts to improve water management and operational efficiency. AIC R/kg increased by 12% to R1,173,095/kg (US$2,223/oz) in H1 2026 from R1,046,434/kg (US$1,770/oz) in H1 2025, due to higher cost of sales before amortisation and depreciation, higher capital expenditure and higher royalty cost, partially offset by 6% higher gold sold. Total capital expenditure increased by 6% to R986m (US$60m) in H1 2026 from R930m (US$51m) in H1 2025, due to higher capital development and an increase in fleet refurbishments. Adjusted free cash flow increased by 84% to R5,763m (US$351m) in H1 2026 from R3,126m (US$170m) in H1 2025. The increase is mainly due to higher gold sold, and higher gold prices received. 13 GOLD FIELDS H1 Results 2026 Review of operations continued Damang June 2026 June 2025 % Variance Ore mined 000 tonnes 779 10 7,690 Waste (Operational) 000 tonnes 6,101 516 1,082 Total waste mined 000 tonnes 6,101 516 1,082 Total tonnes mined 000 tonnes 6,880 526 1,208 Grade mined g/t 0.75 0.78 (4) Gold mined 000’oz 18.8 0.2 9,300 Strip ratio waste/ ore 7.8 53.3 (85) Tonnes milled 000 tonnes 1,333 2,327 (43) Yield g/t 0.52 0.69 (25) Gold produced 000’oz 22.1 51.7 (57) Gold sold 000’oz 22.7 51.7 (56) AISC US$/oz 4,166 2,070 101 AIC US$/oz 4,166 2,070 101 Sustaining capital expenditure US$m — (2.7) (100) Non-sustaining capital expenditure US$m — — — Total capital expenditure US$m — (2.7) (100) Adjusted free cash flow US$m (79.3) 60.4 (231) The Damang mine was formally transferred to the Government of Ghana on 18 April 2026 following the expiry of the 12-month mining lease that was granted to Gold Fields in April 2025. As a result of the transfer, comparisons to prior periods are not on a like-for-like basis. Gold production decreased by 57% to 22,100oz in H1 2026 from 51,700oz in H1 2025 due to lower yield and lower tonnes milled. Yield decreased by 25% to 0.52g/t in H1 2026 from 0.69g/t in H1 2025 due to lower grade fed. AIC increased by 101% to US$4,166/oz in H1 2026 from US$2,070/oz in H1 2025 due to lower gold sold. In H1 2026, gold sold decreased by 56% to 22,700oz from 51,700oz in H1 2025 due to lower gold produced. Adjusted free cash flow for Damang decreased by 231% to a negative US$79m in H1 2026 from US$60m in H1 2025, mainly due to lower revenue driven by lower gold sold. 14 GOLD FIELDS H1 Results 2026 Review of operations continued Tarkwa June 2026 June 2025 % Variance Ore mined 000 tonnes 4,004 5,552 (28) Waste (Capital) 000 tonnes 24,362 17,726 37 Waste (Operational) 000 tonnes 17,837 24,133 (26) Total waste mined 000 tonnes 42,199 41,859 1 Total tonnes mined 000 tonnes 46,203 47,411 (3) Grade mined g/t 1.16 1.15 1 Gold mined 000’oz 149.7 204.8 (27) Strip ratio waste/ ore 10.5 7.5 40 Tonnes milled 000 tonnes 7,045 7,441 (5) Yield g/t 0.85 0.97 (12) Gold produced 000’oz 191.9 232.9 (18) Gold sold 000’oz 192.7 233.8 (18) AISC US$/oz 2,671 2,035 31 AIC US$/oz 2,725 2,035 34 Sustaining capital expenditure US$m 158.3 118.2 34 Non-sustaining capital expenditure US$m 10.3 — 100 Total capital expenditure US$m 168.6 118.2 43 Adjusted free cash flow US$m 278.5 206.5 35 Gold production decreased by 18% to 191,900 in H1 2026 from 232,900oz in H1 2025 due to lower yield and lower tonnes milled. Yield decreased by 12% to 0.85g/t in H1 2026 from 0.97g/t in H1 2025 due to lower grade fed. In H1 2026, 3.61Mt was fed from ex-pit at a grade of 1.15g/t and 3.43Mt from stockpile at a grade of 0.74g/t compared to 4.68Mt from ex-pit at a grade of 1.19g/t and 2.76Mt from stockpile at a grade of 0.81g/t in H1 2025. Tonnes milled decreased by 5% to 7.04Mt in H1 2026 from 7.44Mt in H1 2025 due to lower plant availability resulting from extended downtime to repair the SAG mill trunnion journal. AIC increased by 34% to US$2,725/oz in H1 2026 from US$2,035/oz in H1 2025 due to lower gold sold and higher capital expenditure. In H1 2026, gold sold decreased by 18% to 192,700oz from 233,800oz in H1 2025 due to lower gold produced. Total capital expenditure increased by 43% to US$169m in H1 2026 from US$118m in H1 2025 due to higher capital waste stripping and infrastructure relocation. Adjusted free cash flow for Tarkwa increased by 35% to US$279m in H1 2026 from US$207m in H1 2025, mainly due to higher revenue driven by a higher gold price. 15 GOLD FIELDS H1 Results 2026 Review of operations continued Salares Norte June 2026 June 2025 % Variance Ore mined 000 tonnes 2,359 930 154 Waste (capital) 000 tonnes 3,554 11,675 (70) Waste (operational) 000 tonnes 5,018 424 1,083 Total waste mined 000 tonnes 8,572 12,099 (29) Total tonnes mined 000 tonnes 10,931 13,029 (16) Strip ratio waste/ ore 3.63 13.01 (72) Grade mined – gold g/t 4.75 4.91 (3) Grade mined – silver g/t 77.06 152.55 (49) Gold mined 000’oz 360.2 146.9 145 Silver mined 000’oz 5,843.6 4,563.0 28 Tonnes milled 000 tonnes 1,035 469 121 Gold recoveries per cent 92 % 85 % 8 Silver recoveries per cent 81 % 56 % 45 Yield - Gold g/t 8.8 8.0 10 - Silver g/t 76.7 17.5 338 - Combined eq g/t 10.1 8.2 23 Gold produced 000’oz 294.3 120.8 144 Silver produced 000’oz 2,553.1 264.2 866 Total equivalent gold produced 000’ eq oz 336.9 123.6 173 Total equivalent gold sold 000’ eq oz 333.8 123.8 170 AISC US$/oz 269 1,689 (84) AISC US$/ eq oz 837 1,720 (51) AIC US$/oz 338 2,328 (85) AIC US$/ eq oz 897 2,345 (62) Sustaining capital expenditure US$m 36.2 143.6 (75) Non-sustaining expenditure US$m 10.6 66.8 (84) Total capital expenditure US$m 46.8 210.4 (78) Adjusted free cash flow US$m 1,191.4 122.0 877 Gold production increased by 144% to 294,300oz in H1 2026 from 120,800oz in H1 2025 and silver production increased by 866% to 2,553,100oz in H1 2026 from 264,200oz in H1 2025. Gold- equivalent production increased by 173% to 336,900eqoz in H1 2026 from 123,600eqoz in H1 2025. The above increases were driven by higher tonnes milled and improved gold and silver recoveries following the ramp-up of the operation. AIC decreased by 85% to US$338/oz in H1 2026 from US$2,328/oz in H1 2025, mainly due to the significant increase in production and sales volumes, and decrease in capital expenditure as the operation transitioned from construction and ramp-up to production. Total capital expenditure decreased by 78% to US$47m in 2026 from US$210m in H1 2025, primarily reflecting the completion in 2025 of major winterisation and plant-readiness works.

The decreases are mainly explained by lower head grades, combined with lower throughput and metallurgical recoveries as result of ore ageing. Consequently, total equivalent gold production decreased by 42% to 56,900oz in H1 2026 from 97,400oz in H1 2025. Production in H1 2026 resulted from the processing of low-grade stockpiles, as planned in the mine schedule for treatment from 2026 onwards. AIC per gold ounce increased by 265% to US$1,616/oz in H1 2026 from US$443/oz in H1 2025, mainly due to lower gold sold and the negative impact of the gold inventory change. Total capital expenditure increased by 31% to US$6m in H1 2026 from US$5m in H1 2025, due to the In-pit Tailing construction activities during H1 2026. Adjusted free cash flow for Cerro Corona decreased by 38% to US$71m in H1 2026, compared to US$115m in H1 2025. This decrease was primarily driven by lower revenues resulting from reduced sales volumes of gold and copper. 17 GOLD FIELDS H1 Results 2026 Cash dividend In line with the Company’s dividend policy, the Board has approved and declared an interim dividend number 104 of 1,625 SA cents per ordinary share (gross) in respect of the six months ended 30 June 2026.

The royalty in respect of refined minerals (which include gold refined to 99.5% and above and platinum) is calculated by dividing earnings before interest and taxes (EBIT) by the product of 12.5 times gross revenue calculated as a percentage, plus an additional 0.5%. EBIT refers to taxable mining income (with certain exceptions such as no deduction for interest payable and foreign exchange losses) before assessed losses but after capital expenditure. A maximum royalty of 5% has been introduced on refined minerals. During the period ended 30 June 2026, both GFO and GFIJVH fully utilised their available unredeemed capital expenditure balances, resulting in an effective royalty tax rate of 4.0% of mining revenue (2025: 1.8%). 2 The Australian operations are subject to a 2.5% (2025: 2.5%) gold royalty on revenue as the mineral rights are owned by the state. 3 Minerals are owned by the Republic of Ghana and held in trust by the President. In 2016, Gold Fields signed a Development Agreement (DA) with the Government of Ghana for both the Tarkwa and Damang mines. This agreement stated that the Ghanaian operations will be subject to a mining royalty calculated on a sliding scale with rates ranging from 3% to 5%, linked to the prevailing gold price. Tarkwa’s initial tax stability period under the DA is valid until 17 April 2027. Damang’s mining lease and DA expired on 18 April 2025, however following negotiations with the Government of Ghana, a one year extension, which was ratified by Parliament was granted to 18 April 2026. Ownership of Damang was transferred to the Government of Ghana effective 18 April 2026. In December 2025, the Government of Ghana tabled a Legislative Instrument (LI) in Parliament to effect new regulations which introduce new royalty rates in Ghana for gold and other minerals (including Lithium). The LI was approved effective 10 March 2026 with a royalty range of 5% to 12% on a sliding scale, depending on global gold prices. As a measure of relief, The Government of Ghana subsequently reduced the Growth and Sustainability Levy from 3% to 1%. Gold Fields has a Development Agreement (DA), which provides a range of fiscal concessions and includes key stabilising provisions in relation to taxes, royalties and other matters. The DA protects Tarkwa from these royalty changes until April 2027. 4 The Peruvian operations are subject to a mining royalty calculated on a sliding scale with rates ranging from 1% to 12% of the value of operating profit. 27 GOLD FIELDS H1 Results 2026 Notes to the condensed consolidated financial statements continued United States Dollar Six months ended Figures in millions unless otherwise stated June 2026 June 2025 8. Mining and income taxation The components of mining and income tax are the following: South African taxation – company and capital gains taxation (3.5) (2.8) – withholding tax (14.6) (15.3) – mining taxation1 (15.2) — – non-mining taxation2 (0.6) (0.2) – prior year adjustment - current taxation 1.4 — – deferred taxation (85.0) (77.4) Foreign taxation – current taxation (892.7) (361.5) – withholding tax (52.8) — – prior year adjustment – current taxation (40.0) — – deferred taxation (80.8) (107.8) Total mining and income taxation (1,183.8) (565.0) South Africa – current tax rates Mining tax1 Y=33-165/X Y=33-165/X Non-mining tax2 27.0% 27.0% Company tax rate 27.0% 27.0% International operations – current tax rates Australia 30.0% 30.0% Ghana 32.5% 32.5% Peru 29.5% 29.5% Chile 27.0% 27.0% 1 South African mining tax on mining income is determined according to a formula which takes into account the profit and revenue from mining operations. South African mining taxable income is determined after the deduction of all mining capital expenditure, with the proviso that this cannot result in an assessed loss. Capital expenditure amounts not deducted are carried forward as unredeemed capital expenditure to be deducted from future mining income. Accounting depreciation is ignored for the purpose of calculating South African mining taxation. The mining tax rate used for deferred tax purposes for Gold Fields Operations Limited (GFO) and GFI Joint Venture Holdings (Proprietary) Limited (GFIJVH), owners of the South Deep mine, has been calculated at 30% (2025: 29%). During the period ended 30 June 2026, GFO fully utilised its available assessed mining losses and unredeemed capital expenditure, resulting in an effective mining tax rate of 24% as determined by the gold mining tax formula. In the formula above, Y is the percentage rate of tax payable and X is the ratio of mining profit, after the deduction of redeemable capital expenditure, to mining revenue expressed as a percentage. 2 Non-mining income of South African mining operations consists primarily of interest income. The corporate income tax rate is 27%. Deferred tax is provided at the expected future rate for mining operations arising from temporary differences between the carrying values and tax values of assets and liabilities. In South Africa the tax rate which has been used for deferred tax purposes for mining assets is Y = 33 – 165/X and for non-mining assets is 27%. 9. Discontinued operation The Damang mine was transferred to the Government of Ghana on 18 April 2026, following the expiry of the 12-month mining lease granted to Gold Fields in April 2025 On 18 April 2026, Damang qualified as an abandoned asset and the financial results of Damang have been presented as a discontinued operation in the consolidated financial statements.

Assets held for sale Royalties — 77.5 Assets held for sale — 77.5 On 12 December 2025, Gold Fields entered into agreements to sell a portfolio of royalty assets for a total cash consideration of US$115.0m and its right to the Asanko deferred and contingent considerations for US$30.0m and US$22.0m, respectively. Certain assets within the royalty portfolio, having a combined a value of US$77.5m, were subject to a third-party right of first refusal (“ROFR”). Completion of the overall transaction was conditional upon the purchaser acquiring these royalties. At 31 December 2025, the US$77.5m royalties were presented as assets held for sale as the sale was considered highly probable in the sense that they will be purchased either by the purchaser or the third party. At that date, the outcome of the ROFR was unknown and no evidence existed that the sale of the remaining royalty portfolio amounting to US$37.5m or the deferred and contingent considerations were highly probably and therefore they were not recognised as held for sale. The third party was given until 13 January 2026 to exercise its ROFR, which they declined. As a result, the sale of the remaining royalty portfolio and the Asanko deferred and contingent considerations become unconditional. On this date, a fair value gain of US$37.5m was recognised through profit or loss. The transaction concluded in Q2 2026 with the receipt of US$115.0m and US$52.0m, respectively, for the sale of the royalty portfolio and the Asanko deferred and contingent considerations.

Notes to the condensed consolidated financial statements continued 14. Fair value hierarchy The Group has the following hierarchy for measuring the fair value of assets and liabilities at the reporting date: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2: Inputs other than quoted prices in level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices); and Level 3: Inputs for the asset or liability that are not based on observable market data (unobservable inputs). The Group recognises transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred. There were no transfers during the period ended 30 June 2026 and year ended 31 December 2025. The following table sets out the Group's financial assets and financial liabilities by level within the fair value hierarchy at the reporting date: United States Dollar 30 June 2026 31 December 2025 Figures in millions unless otherwise stated Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Financial assets measured at fair value Trade receivables from provisional copper sales 8.8 — 8.8 — 31.0 — 31.0 — Investments – listed 126.6 126.6 — — 142.4 142.4 — — Asanko contingent consideration — — — — 22.0 — — 22.0 Royalties - asset held for sale — — — — 77.5 — — 77.5 Financial assets not measured at fair value Environmental trust funds 190.0 — 190.0 — 140.9 — 140.9 — Other investments - mainly bonds 47.9 47.9 — — 47.2 47.2 — — Asanko deferred consideration — — — — 28.1 — 28.1 — Financial liabilities not measured at fair value Borrowings 2,204.0 932.5 — 1,271.5 2,806.3 1,309.6 — 1,496.7 Trade receivables from provisional copper sales Valued using quoted market prices based on the forward London Metal Exchange (LME) and, as such, classified within level 2 of the fair value hierarchy. Investments – listed Comprise equity investments in listed entities and therefore valued using quoted market prices in active markets. Royalties - asset held for sales The royalties are measured at fair value. The fair value is based on the expected cash flows of the consideration receivable in terms of the contract. Refer note 12 for further details. Asanko contingent and deferred considerations The contingent consideration is measured at fair value and the deferred consideration is measured at amortised cost. The values of the considerations are based on the expected cash flows of the consideration receivable. The key inputs used in the valuations are the contractually agreed periods and the discount rates. Refer note 12 for further details. Environmental trust funds The trust funds consist of term deposits in South Africa as well as secured cash deposits in Ghana. The environmental trust funds are measured at amortised cost which approximates fair value based on the nature of the fund’s underlying investments. Other investments – mainly bonds Comprise listed bonds and unlisted investments and warrants that are measured at amortised cost which approximates fair value. The fair value of the bonds is determined using quoted market prices in active markets. Borrowings The 10-year notes and 7-year notes (2025: five-year notes and 10-year notes) are issued at a fixed interest rate. The fair values of these notes are based on listed market prices and are classified within level 1 of the fair value hierarchy. The fair value of the remaining borrowings approximates their carrying amount, determined using the discounted cash flow method using market related interest rates and are classified within level 3 of the fair value hierarchy. 33 GOLD FIELDS H1 Results 2026 Notes to the condensed consolidated financial statements continued 15.

Events after the reporting date Interim dividend On 25 August 2026, Gold Fields declared a final dividend of 1,625 SA cents per share. Shareholder returns In November 2025, Gold Fields allocated US$500m to additional shareholder returns, increasing this to US$750m in February 2026. On 25 August 2026, a further US$500m is being allocated to shareholder returns, lifting the additional returns programme to US$1.25b to be delivered through a combination of special dividends and targeted share buy-backs. Of the US$1.25b programme, US$253m was paid out as a special dividend in February 2026 while US$300million has been delivered through the share buy-backs, completed in July 2026. 34 GOLD FIELDS H1 Results 2026 Segmental operating and financial results United States Dollar South African Rand Figures in millions unless otherwise stated Total Mine Operations including Discontinued Operations Total Mine Operations excluding Discontinued Operations Peru Chile Ghana South Africa Cerro Corona Salares Norte Project Tarkwa South Deep South Deep1 Operating results Ore milled/treated (000 tonnes) June 2026 22,281 20,947 3,186 1,035 7,045 1,470 1,470 June 2025 20,893 18,566 3,276 469 7,441 1,534 1,534 Yield (grams per tonne) June 2026 1.8 1.9 0.6 10.1 0.8 3.2 3.2 June 2025 1.7 1.9 0.9 8.2 1.0 3.1 3.1 Gold produced (000 managed equivalent ounces) June 2026 1,298.5 1,276.5 56.9 336.9 191.9 151.0 4,698 June 2025 1,170.7 1,118.9 97.4 123.6 232.9 153.1 4,762 Gold produced (000 attributable equivalent ounces) June 2026 1,266.5 1,246.6 56.6 336.9 172.7 140.6 4,374 June 2025 1,136.2 1,089.7 96.9 123.6 209.7 147.6 4,592 Gold sold (000 managed equivalent ounces) June 2026 1,291.8 1,269.1 56.0 333.8 192.7 147.2 4,579 June 2025 1,125.8 1,074.1 95.2 123.8 233.8 139.5 4,340 Gold price received (Dollar per equivalent ounce) June 2026 4,681 4,678 4,718 4,700 4,634 4,682 2,470,420 June 2025 3,089 3,089 3,198 3,105 3,073 3,081 1,821,525 AISC (Dollar per ounce) June 2026 1,878 1,834 1,284 269 2,671 2,169 1,144,353 June 2025 1,666 1,646 319 1,689 2,035 1,770 1,046,434 Total AIC (Dollar per ounce) June 2026 1,986 1,945 1,616 338 2,725 2,223 1,173,095 June 2025 1,844 1,833 443 2,328 2,035 1,770 1,046,434 The average US Dollar/Rand exchange rates were US$1 = R16.41 for 2026 and US$1 = R18.39 for 2025 The average Australian/US Dollar exchange rates were A$1 = US$0.70 for 2026 and A$1 = US$0.63 for 2025 1 For South Africa, all financial numbers are in Rand and Rand per kilogram Figures may not add as they are rounded independently 35 GOLD FIELDS H1 Results 2026 Segmental operating and financial results continued United States Dollar Australian Dollar United States Dollar Figures in millions unless otherwise stated Australia Australia2 Discontinued Agnew St Ives Granny Smith Gruyere3 Agnew St Ives Granny Smith Gruyere3 Damang Operating results Ore milled/treated (000 tonnes) June 2026 624 2,165 770 4,652 624 2,165 770 4,652 1,333 June 2025 598 2,294 705 2,249 598 2,294 705 2,249 2,327 Yield (grams per tonne) June 2026 5.1 2.4 6.0 0.8 5.1 2.4 6.0 0.8 0.5 June 2025 6.3 2.5 5.9 1.0 6.3 2.5 5.9 1.0 0.7 Gold produced (000 managed equivalent ounces) June 2026 102.8 169.8 147.4 119.7 102.8 169.8 147.4 119.7 22.1 June 2025 121.5 184.5 133.8 72.1 121.5 184.5 133.8 72.1 51.7 Gold produced (000 attributable equivalent ounces) June 2026 102.8 169.8 147.4 119.7 102.8 169.8 147.4 119.7 19.9 June 2025 121.5 184.5 133.8 72.1 121.5 184.5 133.8 72.1 46.5 Gold sold (000 managed equivalent ounces) June 2026 102.6 169.8 144.3 122.7 102.6 169.8 144.3 122.7 22.7 June 2025 112.5 168.7 128.7 71.9 112.5 168.7 128.7 71.9 51.7 Gold price received (Dollar per equivalent ounce) June 2026 4,653 4,712 4,670 4,647 6,623 6,706 6,646 6,614 4,823 June 2025 3,042 3,080 3,080 3,099 4,797 4,856 4,856 4,887 3,091 AISC (Dollar per ounce) June 2026 2,231 2,283 1,787 3,081 3,175 3,249 2,543 4,385 4,166 June 2025 1,373 1,627 1,506 1,878 2,165 2,565 2,374 2,961 2,070 Total AIC (Dollar per ounce) June 2026 2,391 2,653 1,816 3,088 3,403 3,775 2,585 4,394 4,166 June 2025 1,637 2,072 1,537 1,878 2,581 3,267 2,423 2,961 2,070 The average US Dollar/Rand exchange rates were US$1 = R16.41 for 2026 and US$1 = R18.39 for 2025 The average Australian/US Dollar exchange rates were A$1 = US$0.70 for 2026 and A$1 = US$0.63 for 2025 2 For Australia, all financial numbers are in Australian Dollar 3 Results are reported on a 50% basis up to the acquisition of Gold Road on 26 September 2025, and on a 100% basis from that date forward Figures may not add as they are rounded independently 36 GOLD FIELDS H1 Results 2026

This improvement was primarily driven by higher contributions from destress mining volumes, and grade improvements in both development and destress, which are influenced by mining sequence. As destress cuts advanced into reef horizons, waste mining decreased by 31% compared to the March quarter. Surface tonnes milled decreased by 33% from 322kt in the March quarter to 217kt in the June quarter due to scheduled maintenance associated with the thickened tailings project, which is aimed at reducing the volume of water reporting to the tailings storage facility. Backfill volumes placed decreased by 25% during the quarter, as available voids were largely filled in the March 2026 quarter. Backfill placement is expected to increase in the September 2026 quarter as additional voids become available for filling. AIC R/kg increased by 1% to R1,178,231/kg (US$2,225/oz) due to higher royalty cost linked to higher revenue and net profit, and higher cost of sales before amortisation and depreciation, partially offset by higher gold sold (10% increase quarter on quarter).

As a result of the transfer, comparisons to prior periods are not on a like for like basis. Gold production decreased by 84% to 3,100oz in the June quarter from 19,000oz in the March quarter due to lower milled tonnes. Tonnes milled decreased by 84% to 186kt in the June quarter from 1,147kt in the March quarter due to cessation of operations on 17 April 2026. AIC increased by 132% to US$8,192/oz in the June quarter from US$3,537/oz in the March quarter mainly due to lower gold sold partly offset by lower operating cost and royalties. Gold sold decreased by 84% to 3,100oz in the June quarter from 19,600oz in the quarter due to lower gold produced. 49 GOLD FIELDS H1 Results 2026 Review of operations continued Tarkwa June 2026 March 2026 % Variance Ore mined 000 tonnes 2,469 1,535 61 Waste (Capital) 000 tonnes 8,665 15,697 (45) Waste (Operational) 000 tonnes 10,889 6,948 57 Total waste mined 000 tonnes 19,554 22,645 (14) Total tonnes mined 000 tonnes 22,023 24,180 (9) Strip ratio waste/ ore 7.9 14.7 (46) Grade mined g/t 1.09 1.29 (16) Gold mined 000’oz 86.2 63.4 36 Tonnes milled 000 tonnes 3,621 3,423 6 Yield g/t 0.84 0.86 (2) Gold produced 000’oz 97.5 94.4 3 Gold sold 000’oz 97.4 95.3 2 AISC US$/oz 2,376 2,973 (20) AIC US$/oz 2,482 2,973 (17) Sustaining capital expenditure US$m 62.5 95.8 (35) Non-sustaining capital expenditure US$m 10.3 — 100 Total capital expenditure US$m 72.8 95.8 (24) Gold production increased by 3% to 97,500oz in the June quarter from 94,400oz in the March quarter due to higher milled tonnes. Tonnes milled increased by 6% to 3,621kt in the June quarter from 3,423kt in the March quarter due to higher plant availability and utilisation in the June quarter. AIC decreased by 17% to US$2,482/oz in the June quarter from US$2,973/oz in the March quarter mainly due to lower GIP cost and lower capital expenditure. GIP cost decreased by 138% to a credit of US$14.6m in the June quarter from a cost of US$38.3m in the March quarter mainly due to addition of 0.15Mt to run of mine (ROM) stockpile in the June quarter compared to a depletion of 1.59Mt in the March quarter. Total capital expenditure decreased by 24% to US$73m in the June quarter from US$96m in the March quarter mainly due to lower capital waste tonnes mined in the June quarter. 50 GOLD FIELDS H1 Results 2026 Review of operations continued Salares Norte June 2026 March 2026 % Variance Ore mined 000 tonnes 1,491 868 72 Waste (capital) 000 tonnes 2,323 1,231 89 Waste (operational) 000 tonnes 1,877 3,141 (40) Total waste mined 000 tonnes 4,200 4,372 (4) Total tonnes mined 000 tonnes 5,691 5,240 9 Strip ratio waste/ ore 2.82 5.04 (44) Grade mined – gold g/t 5.15 4.05 27 Grade mined – silver g/t 85.51 62.54 37 Gold mined 000’oz 247.1 113.1 118 Silver mined 000’oz 4,098 1,745 135 Tonnes milled 000 tonnes 530 505 5 Gold recoveries per cent 93 91 2 Silver recoveries per cent 80 81 (1) Yield – gold g/t 8.6 9.1 (5) – silver g/t 63.4 90.7 (30) – combined eq g/t 9.6 10.7 (10) Gold produced 000’oz 146.1 148.2 (1) Silver produced 000’oz 1,079.9 1,473.2 (27) Total equivalent gold produced 000’ eq oz 163.7 173.3 (6) Total equivalent gold sold 000’ eq oz 162.8 171.0 (5) AISC US$/oz 436 102 327 AISC US$/ eq oz 876 800 10 AIC US$/oz 511 165 210 AIC US$/ eq oz 943 854 10 Sustaining capital expenditure US$m 19.2 17.0 13 Non-sustaining expenditure US$m 7.6 3.1 145 Total capital expenditure US$m 26.8 20.1 33 Gold and silver production for the June 2026 quarter were 146,100oz and 1,079,900oz, respectively. Gold-equivalent production decreased by 6% to 163,700eqoz in the June quarter from 173,300eqoz in the March quarter, mainly due to lower silver production, while gold production remained similar. Tonnes milled increased by 5%, and gold recovery improved to 93%. During the June quarter, the operation remained focused on delivering the production plan and advancing winter-readiness and plant reliability initiatives to support stable performance through the winter season. AIC increased by 210% to US$511/oz in the June quarter from US$165/oz in the March 2026 quarter, mainly reflecting lower silver by-product credits and higher capital expenditure. Total capital expenditure increased by 33% to US$27m in the June quarter from US$20m in the March 2026 quarter, primarily due to higher expenditure on AA pre-stripping activities as well as winter-readiness and plant reliability initiatives. 51 GOLD FIELDS H1 Results 2026 Review of operations continued Cerro Corona June 2026 March 2026 % Variance Tonnes milled 000 tonnes 1,592 1,594 — Gold recovery per cent 67.5 68.7 (2) Copper recovery per cent 82.8 85.5 (3) Yield – gold g/t 0.33 0.32 3 – silver per cent 0.29 0.29 — – combined eq g/t 3.52 0.54 552 Gold produced 000’oz 16.0 16.0 — Copper produced tonnes 4,489 4,441 1 Total equivalent gold produced 000’ eq oz 29.2 27.7 5 Total equivalent gold sold 000’ eq oz 26.1 29.9 (13) AISC US$/oz 1,412 1,179 20 AISC US$/ eq oz 3,015 2,698 12 AIC US$/oz 1,928 1,360 42 AIC US$/ eq oz 3,294 2,802 18 Sustaining capital expenditure US$m 0.6 (0.2) (400) Non-sustaining capital expenditure US$m 4.1 1.4 193 Total capital expenditure US$m 4.7 1.2 292 Gold-equivalent production increased by 5% to 29,200oz in the June quarter from 27,700oz in the March quarter, mainly due to slightly higher gold and copper grades processed, in line with the rehandle sequence of stockpiles. AIC per gold ounce sold increased by 42% to US$1,928/oz in the June quarter from US$1,360/oz in the March quarter, mainly due to lower gold ounces sold, and higher exploration and capital expenditures in the June quarter compared to the March quarter. Total capital expenditure increased by 292% to US$5m in the June quarter from US$1m in the March quarter, mainly due to the construction activities of the in-pit tailings deposition system after the rainy season, which will be completed in July 2026. 52 GOLD FIELDS H1 Results 2026

All statements other than statements of historical fact included in this announcement may be forward-looking statements. Forward-looking statements may be identified by the use of words such as “aim”, “anticipate”, “will”, “would”, “expect”, “may”, “could”, “believe”, “target”, “estimate”, “project” and words of similar meaning. These forward-looking statements, including among others, those relating to Gold Fields’ future business strategy, development activities (including the approvals, permitting, development operations and final investments decisions relating to the Windfall Project) and other initiatives, anticipated benefits of acquisitions or joint ventures, (including the acquisition of Gold Road Resources Limited), ability to successfully renew, extend and/or retain mining rights, licences, development or fiscal stability agreements, or other interests (including the satisfaction of licence conditions), ability to conclude divestments on favourable terms (if at all), business prospects, financial positions, production and operational guidance, climate and ESG- related statements, targets and metrics, are necessary estimates reflecting the best judgement of the senior management of Gold Fields and involve a number of risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements. By their nature, forward-looking statements involve risk and uncertainty because they relate to future events and circumstances and should be considered in light of various important factors, including those set forth in Gold Fields’ Integrated Annual Report 2025 filed with the Johannesburg Stock Exchange and the Annual Report on Form 20-F filed with the United States Securities and Exchange Commission (SEC) on 30 March 2026 (SEC File no. 001-31318).
