Statement by Mike Fraser, CEO Gold Fields delivered strong results in 2025, with a significant improvement in our safety, operational and financial performance, compared to 2024. Most importantly, the benefits of our Safety Improvement Plan, which commenced in 2024 resulted in no fatalities at any of our operations in 2025. There were seven serious injuries recorded during the year and this reminds us of the ongoing focus required to achieve our goal of ensuring all our people return home safe and well every day. We continued to embed our functional operating model and improve our systems and processes, providing the platform for reliable delivery of our strategy and long-term aspirations. We also identified asset optimisation initiatives across our portfolio which were communicated to the market with our H1 2025 results in August 2025 and again at our Capital Markets Day in November 2025. These initiatives are aimed at enhancing the value and life of our mines by improving efficiencies, reducing operating costs, extending the lives of our mines, and in some cases, increasing production. At our inaugural Capital Markets Day, we provided a five-year outlook for the Group, together with five-year profiles for individual assets. This outlook demonstrates the significant opportunities within our portfolio and the levers to deliver increased value. We also presented our enhanced capital allocation framework which included a change to our dividend policy. The new policy, which will take effect with the final FY 2025 dividend declaration, targets a base dividend of 35% of free cash flow before discretionary growth investments, with a minimum annual dividend of US$0.50 per share1. In addition, we communicated our intention to provide additional returns to shareholders of up to US$500m2 over the next 24 months based on current cash flow projections, in the form of special dividends and/or share buybacks3,4. Operationally, we delivered a more predictable performance in 2025, keeping guidance unchanged throughout the year, delivering production at the upper end of guidance and costs within the guided range. Group attributable gold-equivalent production increased 18% to 2,438koz in 2025, underpinned by strong performances across the portfolio. Salares Norte delivered a particularly strong second half performance, reaching commercial production in Q3 2025 and steady state by year-end, with the mine delivering above the upper end of its guidance. The improved operational performance, coupled with the higher gold price, resulted in a strong financial performance in 2025. The Group generated adjusted free cash flow of US$2,970 million compared to US$605 million in 2024 and headline earnings of US$2,576 million compared to US$1,188 million in 2024. In line with our updated dividend policy, we have declared a final dividend of R18.50 per share, which is 164% higher than the final dividend paid last year. When combined with the interim dividend of R7.00 per share, the total dividend of R25.50 per share (US$1.60 per share) equates to 35% of free cash flow before discretionary investments, in line with our targeted 35%. In addition to the base dividend, Gold Fields will distribute US$353 million in additional returns. This will comprise US$253 million in special dividends and US$100 million in share buy-backs, broadly aligned with the preferences and composition of our shareholder register. Combined with the base dividend, this results in a total distribution to shareholders of US$1.7 billion which equates to 54% of adjusted free cash flow.

Looking ahead, our priorities for 2026 include advancing our Safety Improvement Plan, and optimising our operating model, systems and processes which provide the platform for safe, reliable and cost-effective production delivery. Strategically, we are focused on advancing the renewal of the Tarkwa mining leases, while ensuring the smooth transition of the Damang mine to the Government of Ghana. At the Windfall Project in Canada, we are progressing permitting approvals, the Impact Benefit Agreement and advancing project studies to Final Investment Decision (FID). Finally, we intend to progress the value-enhancing organic opportunities presented to the market in November, including: • Integration of the Yamarna and Golden Highway land tenements at Gruyere; • Gruyere open pit and underground studies; • St Ives and Granny Smith material handling system studies; • Preparation for the pre-stripping activities at Aqua Amarga; • Santa Ana and Invincible underground life-extension study at St Ives; and • South of Wrench feasibility study at South Deep Delivering on our strategy During 2025, we continued to execute our three-pillar strategy to: • Operate in a safe, reliable and cost-effective way • Have a positive impact on our communities and the environment, and • Grow the quality of our portfolio We believe that the consistent delivery of this strategy will drive improved margins and free cash flow per share, strengthen our position relative to peers and enhance returns for our shareholders. Operate in a safe, reliable and cost-effective way Safety and wellbeing We remain steadfast in our belief in fatality- and serious injury-free mining and are committed to eliminating fatalities, serious injuries and occupational diseases. Safety performance improved materially during 2025, with the achievement of zero fatalities and six consecutive fatality-free quarters, an important milestone in Gold Fields’ history. However, seven serious injuries occurred during the year, reinforcing that further progress is required. The disciplined delivery of our Safety Improvement Plan, together with the continued maturation of our culture and operating systems, remains critical to eliminating serious injuries. We continue to reinforce our cultural and operational levers through improving leadership behaviours and mindsets, robust risk management and strengthened health and safety systems and practices. In 2025, we implemented an Occupational Health Framework to prevent workplace exposures and illnesses and to further strengthen workforce wellbeing. Reliable and cost-effective operations Our operational delivery was more predictable in 2025, enabling us to track our operating plans and achieve our guidance for the year. Group attributable gold-equivalent production for FY 2025 was 18% higher year- on-year (YoY) at 2,438koz (FY 2024: 2,071koz). Costs remained elevated in FY 2025 driven by general industry inflation, higher royalties owing to increased realised gold prices, stronger producer currencies and higher capital expenditure. All-In Cost (AIC) increased by 3% YoY to US$1,927/oz (FY 2024: US$1,873/oz) and All-in Sustaining Cost (AISC) increased by 1% YoY to US$1,645/oz (FY 2024: US$1,629/oz), as higher royalties and capital expenditure offset the impact of increased gold sold. Through our asset optimisation programme, we identified a number of improvement opportunities at key assets which are expected to mitigate inflationary impacts going forward. Gruyere had a difficult Q4 2025, with ground instability and rock fall incidents resulting in the resequencing of mining activities to lower- grade areas of the Gruyere pit. Head grade was further impacted as lower-grade stockpiles were processed to supplement ore feed. The mine also experienced increased workforce turnover during H2 2025, resulting in unplanned downtime of production equipment and a decrease in tonnes mined for the period. While these challenges are expected to continue impacting operations at Gruyere in Q1 2026, the team has identified action plans to improve mining performance. These include improving mining fleet equipment availability, implementing optimisation initiatives to unlock mining efficiencies, and engaging with our business partners to strengthen retention and recruitment strategies. Despite the current challenges, we forecast an increase in Gruyere’s production in FY 2026 compared with FY 2025, with production weighted to H2 2026. Tarkwa’s waste stripping campaign continued during 2025. As a result, production decreased by 12% as lower-grade stockpiles were used to supplement the ore feed. AIC increased by 26% YoY driven by lower volumes of gold sold, general mining inflation, a 31% increase in royalties paid and increased capital expenditure. A key focus in the near to medium term is to optimise Tarkwa’s mining costs by improving mining efficiencies, reconfiguring the mining fleet and optimising the mine design. South Deep delivered a strong performance in 2025, with production of 309koz up 16% YoY (FY 2024: 267koz) and achieving the top end of its guidance range. As a highly mechanised, long-life orebody, South Deep remains a cornerstone asset, with the team focused on improving stope turnaround times and driving incremental performance gains. Salares Norte had a successful ramp-up in 2025 with a particularly strong second half. The mine achieved commercial production in Q3 2025 and reached steady state operations in Q4 2025, resulting in production of 397koz eq for FY 2025, which is above the guidance range (325koz eq – 375koz eq). Encouragingly, the plant continued to operate uninterrupted through the winter months, despite still being in the ramp-up phase and experiencing weather events similar to 2024. AISC was US$1,144/oz eq, within the guidance range provided in February 2025. Salares Norte delivered US$808m in free cash flow for the year which was the highest in the Group. Financial performance and capital allocation Gold Fields continued to deliver on its capital allocation priorities during FY 2025. The Group spent US$1,029 million (US$427/oz) in sustaining capital to maintain the integrity of our asset base and declared a total dividend of R25.50/share (interim dividend of R7/share and final of R18.50/share). This represents 35% of free cash flow before discretionary investments, and is in line with our targeted dividend policy of 35%. We also maintained a healthy debt position. Normalised profit increased by 119% YoY to US$2,684 million, or US$3.00 per share in FY 2025 (FY 2024: US$1,227m, or US$1.37 per share), driven by higher gold sales volumes and higher realised gold prices during the period. During FY 2025, the Group generated adjusted free cash flow of US$2,970 million (after considering all costs and project capital expenditure), compared with US$605 million in FY 2024. The mines generated adjusted free cash flow from operations of US$3,171 million in FY 2025 compared with US$1,986 million in FY 2024. Net debt decreased by US$644 million during 2025, despite the US$1.45 billion payment, net of the Northern Star share sale, for the acquisition of Gold Road Resources in October. Gold Fields ended 2025 with a robust balance sheet, with net debt of US$1,442 million (end- December 2024: US$2,086m) and a net debt to adjusted EBITDA ratio of 0.26x (end-December 2024: 0.73x). Excluding lease liabilities, net debt was US$959 million at the end of FY 2025. In May 2025, Gold Fields issued US$750 million seven-year notes with a 5.854% coupon. The proceeds were used to repay amounts outstanding under the US$750 million bridge facilities utilised to fund the acquisition of Osisko Mining in 2024. In October 2025, we utilised a bridge facility to fund the acquisition of Gold Road Resources, which was subsequently partially repaid using the proceeds of an A$1,250m multi-currency term loan arranged in December 2025. At the end of December 2025, the Group’s capital structure consisted of a US$1.2 billion sustainability-linked revolving credit facility (US$637 million undrawn), a US$500 million bond maturing in 2029, the US$750 million notes maturing in 2032, the A$1,250 million multi-currency term loan terminating in December 2030, several smaller in-country facilities and US$1,779 million in cash. Have a positive impact on our communities and the environment Our people are our most important stakeholders. We continue to strengthen our culture by investing in leadership development and enhancing our workplaces. We have implemented all the Elizabeth Broderick & Co. recommendations and successfully achieved our 2025 target of 26% female representation. 2 Gold Fields Reviewed Results 2025

Stakeholder value creation – Since 2020, Gold Fields has delivered substantial national value through employment, procurement and socio-economic development, strengthening trust and social licence to operate. Total value distributed in FY 2025 was US$5.778 billion (FY 2024: US$4.21 billion). Procurement from in-country suppliers was US$1.69 billion, representing 97% of total procurement (FY 2024: US$1.28bn; 97%). Carbon emission reduction – Gold Fields has achieved meaningful improvements in Scope 1 and 2 emissions intensity, improving energy security, reliability and cost resilience. Renewables accounted for 18% of Group electricity consumption in FY 2025 (FY 2024: 18%). Construction of the St Ives hybrid renewable project, comprising a 42MW wind farm and a 35MW solar plant, is approximately 80% complete, with commissioning planned for mid-2026. Environment - We reported zero significant environmental incidents during the period. Freshwater recycled and reused reached 74%, above our 73% target for the year (FY 2024: 74%). Total freshwater withdrawal for FY 2025 was 9.72 GL, an improvement against both FY 2024 (11.09 GL) and our 2025 target of 12.06 GL. Responsible tailings management – Meaningful conformance with the Global Industry Standard on Tailings Management (GISTM) has been achieved, in line with our International Council on Mining and Metals (ICMM) commitment and a comprehensive, multi-year programme, which was planned to meet the requirements of the GISTM across our global assets. Collectively, our progress demonstrates that sustainability is embedded in how Gold Fields operates, driving greater reliability and predictability and strengthening our ability to deliver. Mid-point review – In 2021, Gold Fields established six Environmental, Social and Governance (ESG) targets for 2030. In 2025, at the mid-point to 2030, we undertook a comprehensive review to assess progress, continued relevance and alignment with our longer-term strategy and 2035 aspirations. The review confirmed that: • We have made meaningful progress against our 2030 targets • Changes in external context and portfolio growth require selective refinement of targets to ensure they remain credible and outcome-focused, and • The 2035 aspirations are integral to our strategy and critical to sustaining access to resources and supporting growth The outcome of the review is a refined and extended set of strategic sustainability commitments and targets through to 2035 and beyond from our 2030 trajectory. Net Zero by 2050 remains an objective; however, business growth and portfolio evolution, together with the slower pace of sector-wide technological development and deployment, have reduced the appropriateness of an absolute emissions target. Shifting to a 30% emissions intensity reduction target, by 2035, strengthens our commitment to efficiency and real-world impact, while better reflecting the relationship between production and emissions during growth phases. Our freshwater reuse and recycling performance remains best practice within our peer group. We plan to refine water targets by retaining water, reuse and recycling targets in freshwater catchments, while shifting to more relevant, context-based, asset-specific water targets in saline and hypersaline environments. Nature risk management continues to mature across the portfolio, and we will expand our commitments to measure and disclose nature-related impacts and risks, while implementing projects to enhance habitats affected by our operations. Sustainability is intrinsic to Gold Fields’ purpose, strategy and long-term success. It underpins how we operate today and how we secure access to resources, enable growth opportunities and create value over time. Advancing shared value and empowerment During FY 2025, Gold Fields marked the vesting of the Thusano Trust, our employee share ownership initiative established in 2010 in line with South African Mining Charter requirements applicable at the time. The vesting concluded a 15-year shared value model, enabling qualifying past and current employees to participate in long-term value creation. The Trust benefits 46,007 beneficiaries and was valued at R11.1 billion at vesting date. The share trade process was completed on 15 January 2026. This milestone reflects Gold Fields’ commitment to responsible empowerment and sustainable value creation. Growing the quality of our portfolio Gold Fields’ strategy aims to continually improve the quality of our production base, either through acquiring assets that will enhance the quality of the portfolio or disposing of assets which no longer fit the longer-term vision for the business. In this regard, we disposed of our 19.5% stake in Galiano Gold in September 2025 for a total consideration of C$151 million. We have also entered into definitive agreements to sell a portfolio of royalties and related instruments for US$167 million in cash. This comprises US$115 million from the sale of a royalty portfolio, including a 1.5% NSR on Buenaventura’s San Gabriel gold silver mine, a capped 1.0% NSR on Galiano’s Nkran deposit pit, and NSR and NPI interests over Amarc’s JOY Project, together with several smaller royalties. The remaining US$52 million relates to the sale of our rights to deferred and contingent payments from Galiano Gold associated with the 2023 Asanko transaction. During 2025, we worked closely with the Government of Ghana to develop a transition plan for the Damang mine. In April 2026, the 12-month lease extension comes to an end, at which point Gold Fields will transfer ownership of the mine to the Government of Ghana. 2025 was the final year of mining at Cerro Corona, with the operation expected to process stockpiles from 2026 onwards. While we expect that the mine will continue to produce gold and copper and generate cash flow until 2031, we have begun assessing pathways to realise Cerro Corona’s full value, including potential life-extension opportunities. Gold Road acquisition In October 2025, Gold Fields completed the acquisition of Gold Road Resources and paid US$1.42 billion (A$2.19 billion), 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. Full ownership of Gruyere, together with the surrounding land package, enables Gold Fields to optimise the life-of-mine plan for the asset. The incremental expansion of the processing facility, together with consolidation of Gruyere, Golden Highway and the Yamarna land packages is expected to allow the asset to produce c.400koz on a sustainable basis over an extended period. During 2026, we will advance studies to optimise the value of the Gruyere deposit, including an open-pit cutback versus underground trade-off study. We also plan to accelerate access to the higher-grade material from Golden Highway and the Gilmour deposit to supplement ore feed from the Gruyere pit. Finally, we will increase our exploration efforts across the under-explored 2,000km2 Yamarna land package during 2026. Windfall Project update Gold Fields provided an update on the Windfall Project at our Capital Markets Day in November 2025. The focus remains on advancing the Environmental Impact Assessment (EIA) and secondary permits, signing the Impact Benefit Agreement (IBA) and updating the feasibility study in preparation for the FID. Good progress has been made in finalising the IBA with the Cree First Nation of Waswanipi. During 2026, we plan to advance our multi-year exploration programme across our 2,500km2 land position which covers the Urban Barry and Quévillon belts. The Phoenix JV earn-in with Bonterra Resources is also expected to be completed in H1 2026. 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, which is due to expire in April 2027. We submitted a comprehensive application for the renewal of the Tarkwa mining leases in November 2025, and have commenced discussions with the Government of Ghana on the terms of the renewal. Ghana has proposed mining policy reforms aimed at increasing local participation and state revenues from the industry, which are expected to influence the outcome of these lease renewal discussions. A key component of this process has been updating Tarkwa’s life-of-mine plan and the mine’s declared Mineral Resources and Mineral Reserves. In November 2025, Gold Fields published an out-of-cycle Mineral Resources and Mineral Reserves declaration for Tarkwa. Gold Fields Reviewed Results 2025 3

In the 2025 declaration, managed Mineral Reserves increased to 7.4 million ounces from 4.3 million ounces in the 2024 declaration, and managed Mineral Resources (inclusive of Reserves) increased to 11.2 million ounces, from 8.9 million ounces. Gold Fields’ attributable share, after 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 10.0 million ounces of Resources (inclusive of Reserves). The approximately 70% increase in attributable Reserves was driven by a higher Reserve gold price of known Mineral Resources (as discussed in the Mineral Resource and Reserve update below), together with the removal of key operational constraints, including a reduced Akontansi open pit stand-off distance from infrastructure. A key focus for the team in the near to medium term is to optimise Tarkwa’s operating costs to enhance margins and cash generation and to further increase mineable inventory. Exploration update We continued to advance our greenfields exploration strategy during 2025, building a pipeline of early-stage opportunities to underpin production beyond 2035. During 2025, Gold Fields made a strategic equity investment of C$50 million in Founders Metals, acquiring a 10.5% ownership interest and gaining exposure to the district-scale Antino gold project in Suriname. In Chile, work at Santa Cecilia progressed following Phase 1 drilling, which demonstrated broad zones of low-grade gold–copper mineralisation adjacent to the Norte Abierto development. With Torq Resources as operator, activities focused on technical review and target refinement in preparation for the Phase 2 drilling programme for 2026. In Peru, exploration remained focused on advancing the early-stage portfolio, with land access, permitting and technical programmes progressing across several 100%-owned projects. In Australia, drilling commenced at Brandy in the East Lachlan Belt, targeting a large blind porphyry gold-copper system located proximal to Cadia Valley Operations (Newmont). Drilling and surface programmes were also completed at the Edinburgh Park project in North Queensland, while regional soil sampling and airborne electromagnetic surveys across the West Tanami supported target prioritisation ahead of drilling. The integration of the Gold Road exploration portfolio was completed during H2 2025 following the acquisition, materially expanding our Australian greenfields footprint. Canada remains a core focus, with a drilling programme completed across the Windfall district during H2 2025. Preparations are underway for a drilling programme at the Phoenix joint venture with Bonterra Resources, scheduled to commence in H1 2026. Our equity partner, Onyx Gold, continued to deliver high-grade results at the Munro-Croesus project, supporting the ongoing assessment of its discovery potential. Mineral Resources and Mineral Reserves update Gold Fields’ Mineral Resources and Mineral Reserves are reported as at 31 December 2025 on an attributable basis, with Resources stated exclusive of Reserves. Group gold Reserves increased by 4.0Moz or 9% to 48.3 Moz (2024: 44.3 Moz). Gold Measured and Indicated Resources increased by 13% to 34.2 Moz (2024: 30.4 Moz), while Inferred gold Resources increased by 10% to 12.8 Moz (2024: 11.6 Moz). The increase in Reserves stems from revised gold price assumptions and improving underlying asset quality across the Group. Higher gold prices enabled the economic inclusion of Reserves where substantial, well-defined Resources already existed. Portfolio-specific drivers included the acquisition of Gold Road Resources, increasing Gold Fields’ ownership in the Gruyere mine to 100%, growth at Tarkwa due to revised prices and an updated mine design, and growth at St Ives and Granny Smith driven by successful brownfields exploration. In 2025, the gold price assumptions applied to Mineral Resources and Mineral Reserves were increased to US$2,000/oz (2024: US$1,500/oz) and US$2,300/oz (2024: US$1,725/oz) respectively, reflecting prevailing market conditions. Mineral Resources and Mineral Reserves for the Windfall Project will be included in the Group’s reporting upon completion of the feasibility study and receipt of environmental approvals, expected in 2026. The Mineral Resources and Mineral Reserves Supplement will be published concurrently with the Integrated Annual Report in late March 2026.

Mr Trueman consents to the inclusion of these Mineral Resource and Mineral Reserve statements in the form and context in which they appear. FY 2026 guidance Our primary focus for 2026 remains ensuring safe, reliable and cost- effective delivery against our production plans and guidance for the year, which will provide the platform for continued progress of our strategic priorities. Attributable gold-equivalent production for 2026 is expected to be between 2.400Moz – 2.600Moz (compared to 2.438Moz delivered in 2025). AISC is expected to be between US$1,800/oz – US$2,000/oz, and AIC is expected to be between US$2,075/oz – US$2,300/oz. The exchange rates used for our 2026 guidance are: R/US$16.00, US$/A$0.70 and C$/US$0.73. The metal price assumptions for the calculation of royalties and copper and silver by-products are: gold price US$5,000/oz (A$7,100/oz, R2,450,000kg); copper price US$9,000/t and silver price US$65/oz. 2026 is another year in which capital expenditure levels will remain elevated, given the capital planned budgeted for Windfall, as well as sustaining capital expenditure across the portfolio required to maintain the production base of the Group. Total capital expenditure for the Group for the year is expected to be US$1,900 million – US$2,100 million in 2026. Sustaining capital expenditure is expected to be US$1,300 million – US$1,400 million, while non-sustaining capital expenditure is expected to be US$240 million – US$340 million, with the largest component of this being the Windfall Project capital of C$495 million. Guidance for 2026 remains unchanged from that provided at our Capital Markets Day in November 2025 for production. However, we have seen increases in AISC and AIC, driven primarily by the strengthening of exchange rates in Australia and South Africa as well as the impact of higher gold price on royalty payments. In comparison to the rates disclosed above, the exchange rates used at our Capital Markets Day were R/US$18.50, US$/A$0.67 and C$/US$0.71. The metal price assumptions for the Capital Markets Day were: gold price US$3,872/oz and silver price US$44/oz. The Capital Markets Day also excluded non-core assets (Cerro Corona and Damang). The above is subject to the forward-looking statement on page 63. Mike Fraser Chief Executive Officer 19 February 2026 4 Gold Fields Reviewed Results 2025

The average Canadian/US Dollar exchange rate strengthened by 1% from C$1.00 = US$0.73 to C$1.00 = US$0.72. Cost of sales before amortisation and depreciation Cost of sales before amortisation and depreciation increased by 25% from US$2,216m in 2024 to US$2,760m in 2025 mainly due to the increase in production as well as inflationary increases affecting all the regions and a US$14m gold inventory debit to cost in 2024 compared to US$61m in 2025. Amortisation and depreciation Amortisation and depreciation for the Group increased by 47% from US$627m in 2024 to US$920m in 2025 mainly due to the higher production. Investment income Investment income increased by 83% from US$29m in 2024 to US$53m in 2025 due to higher interest received as a result of higher average cash and cash equivalents during 2025. Finance expense Finance expense for the Group increased by 142% from US$50m in 2024 to US$121m in 2025 due to lower interest capitalised and higher borrowings in 2025. Interest expense on borrowings of US$134m, lease interest of US$26m, rehabilitation interest of US$29m and silicosis liability unwinding of US$1m, partially offset by interest capitalised of US$69m in 2025 compared to interest expense on borrowings of US$106m, lease interest of US$25m, rehabilitation interest of US$25m and silicosis liability unwinding of US$1m, partially offset by interest capitalised of US$106m. The decrease in interest capitalised relates to the cessation of interest capitalisation at Salares Norte from Q3 2025 due to the mine having reached commercial levels of production Share of results of equity-accounted investees after taxation The share of losses of equity-accounted investees after taxation decreased by 96% from US$54m in 2024 to US$2m in 2025.

All-in sustaining and total All-in cost Year-on-year The Group AISC increased by 1% from US$1,629/oz in 2024 to US$1,645/oz in 2025 mainly due to higher cost of sales before amortisation and depreciation, higher royalties, higher share-based payments and long-term incentives and higher sustaining capital expenditure. These increases were partially offset by higher gold sales and higher by-product credits to cost. Total AIC increased by 3% from US$1,873/oz in 2024 to US$1,927/oz in 2025 mainly due to the reasons mentioned above as well as higher non- sustaining capital expenditure and higher exploration costs.

In 2024, Gruyere production was impacted by a wet weather event during March and April. In 2025, Gruyere operations continued to ramp-up, with the Gruyere open pit achieving a 37% increase in tonnes mined compared to the prior year. AIC increased by 27% to A$3,150/oz (US$2,030/oz) in 2025 from A$2,474/oz (US$1,632/oz) in 2024 due to increased capital expenditure on key production growth enablers and higher cost of sales before amortisation and depreciation, partially offset by higher gold sold. The increase in cost of sales before amortisation and depreciation relates mainly to higher mining unit costs as a result of higher contractor mining rates and additional processing plant maintenance costs. Total capital expenditure increased by 89% to A$244m (US$157m) in 2025 from A$129m (US$85m) in 2024, reflecting the 2025 focus on pre-stripping of Stages 5 and 6 of the Gruyere open pit. Following the acquisition of Gold Road on 26 September 2025, capital expenditure has been recognised at 100% of the Gruyere cost profile. Adjusted pre-tax free cash flow for Gruyere increased by 146% to A$458m (US$295m) in 2025 from A$186m (US$123m) in 2024 attributed to the higher gold price and recognition of cash flows at 100% post the acquisition.

AIC increased by 16% to A$2,609/oz (US$1,682/oz) in 2025 from A$2,240/oz (US$1,477/oz) in 2024, driven by higher cost of sales before amortisation and depreciation following increased commodity input prices and employee and contractor costs, as well as higher capital expenditure. This was partially offset by higher gold sold. Total capital expenditure increased by 21% to A$133m (US$86m) in 2025 from A$110m (US$72m) in 2024, driven by increased non-sustaining expenditure in 2025 associated with bringing the Barren Lands underground mine to full production in December 2025 and ongoing development of the lower Kath orebody at the Waroonga complex. Adjusted pre-tax free cash flow increased by 104% to A$671m (US$432m) in 2025 from A$329m (US$217m) in 2024 mainly due to a higher gold price received and higher gold sold.

This increase was primarily driven by improved grades due to the mining footprint and enhanced plant recovery. Gold mined increased by 6% from 9,413kg (302.7Koz) in 2024 to 10,018kg (322.1Koz) in 2025 as destress mining advanced into higher-grade areas in alignment with the business plan. As a result, development activity declined by 5% from 12,530m in 2024 to 11,859m in 2025 as new cuts are established. Both backfill and secondary support recorded increases of more than 25%. Backfill spillage issues were resolved, enabling more areas to be backfilled, while the increase in secondary support was driven by increased rehabilitation efforts in both current and older mining areas as the operation continued to invest in infrastructure integrity and long-term operational stability. AIC R/kg increased marginally from R1,057,462 (US$1,794/oz) in 2024 to R1,058,238 (US$1,841/oz) in 2025 predominantly due to higher capital expenditure, higher royalties and higher cost of sales before amortisation and depreciation, partially offset by higher gold sold. Capital expenditure increased by 12% to R2,292m (US$128m) in 2025 from R2,046m (US$112m) in the 2024 financial period. The main expenditure items relate to an increase in equipment, winder upgrades, electrical upgrades and water reticulation upgrades. Adjusted free cash flow increased by 198% to R9,144m (US$511m) in 2025 from R3,070m (US$168m) in 2024 mainly due to a higher gold price received and increased gold sales.

The contributions are proactive and not legally required by local legislation. 2 The increase in deferred taxation relates mainly to: • An impairment reversal of US$285.1 million in respect of the South Deep CGU (refer note 10); • Utilisation of unredeemed capital expenditure at the South Deep mine as a result of higher taxable profits, driven mainly by the significant increase in gold prices; • Utilisation of tax losses and unredeemed capital expenditure at Salares Norte as a result of ramp-up and achievement of commercial levels of production; and • A net deferred tax liability amounting to US$298.3 million was recognised as part of Gold Road acquisition (refer note 12). 3 Other current liabilities comprise mainly trade and other payables and royalties and taxes payable. Royalties and taxes payable are higher as a result of higher gold prices. 24 Gold Fields Reviewed Results 2025

On 25 October 2024, Gold Fields entered into an agreement with Osisko to acquire 100% of its issued share capital. The only significant asset in Osisko was the additional 50% interest in the Windfall Project.

The Royalty Act imposes a royalty on refined (mineral resources that have undergone a comprehensive level of beneficiation such as smelting and refining as defined in Schedule 1 of the Act) and unrefined (mineral resources that have undergone limited beneficiation as defined in Schedule 2 of the Act) minerals payable to the state. 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. The effective rate of royalty tax payable for the year ended 31 December was 2.4% of mining revenue (2024: 0.5%) equalling the minimum charge per the formula. 3 The Australian operations are subject to a 2.5% (2024: 2.5%) gold royalty on revenue as the mineral rights are owned by the state. 4 Minerals are owned by the Republic of Ghana and held in trust by the President. During 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 sliding scale for royalty rates, linked to the prevailing gold price (effective 1 January 2017). The sliding scale is as follows: Average gold price Low value High value Royalty rate US$0.00 – US$1,299.99 3.0% US$1,300.00 – US$1,449.99 3.5% US$1,450.00 – US$2,299.99 4.1% US$2,300.00 – Unlimited 5.0% 5 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. 28 Gold Fields Reviewed Results 2025

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 effective 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 29% (2024: 29%). 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%. Gold Fields Reviewed Results 2025 29

Assets held for sale (a) Royalties3 77.5 — (b) O3 Mining Inc. (“O3 Mining”)4 — 21.1 Total assets held for sale 77.5 21.1 1 During the year ended 31 December 2018, the Group recognised an impairment of US$409.8 million (R5,507.0 million) in respect of property, plant and equipment relating to the South Deep CGU. At 31 December 2025, the Group reversed an impairment of US$285.1 million (R4,721.9 million) in respect of property, plant and equipment relating to the South Deep CGU as a result of significantly higher gold prices and the stabilisation of the ramp-up at the South Deep mine during 2025. The impairment reversal was limited to what the carrying amounts of the CGU would have been at 31 December 2025 had the assets not been impaired. The recoverable amount at 31 December 2025 was based on its fair value less cost of disposal (“FVLCOD”) calculated using a combination of the market (resource value) and the income approach (level 3 of the fair value hierarchy) and amounted to US$4,163.2 million (R68,941.8 million). The recoverable amount is significantly higher than the carrying value and a reasonable possible change in the assumptions would not change the conclusion to reverse the impairment or the quantum of the reversal. The following assumptions based on the 2025 life-of-mine plan were used in the determination of the recoverable amount: - Gold price: • Year 1 – US$4,060 (R2,190,530) per ounce (2024: US$2,590 (R1,465,000) per ounce); • Year 2 – US$3,960 (R2,189,480) per ounce (2024: US$2,550 (R1,420,000) per ounce); • Year 3 – US$3,810 (R2,177,520) per ounce (2024: US$2,470 (R1,410,000) per ounce); • Year 4 – US$3,580 (R2,070,810) per ounce (2024: US$2,400 (R1,370,000) per ounce); and • Year 5 onwards – US$3,130 (R1,826,740) per ounce (2024: US$2,160 (R1,233,000) per ounce). - Long-term exchange rates: • US$/ZAR year 1 – 16.78 (2024: 17.59); • US$/ZAR year 2 – 17.20 (2024: 17.32); • US$/ZAR year 3 – 17.78 (2024: 17.76); • US$/ZAR year 4 – 17.99 (17.76); and • US$/ZAR - year 5 onwards – 18.15 (17.76). - Life-of mine: 83 years (2024: 85 years); and - Discount rate of 14.3% (2024: 15.9%) (nominal). 2 The Group performed assessments at 31 December 2025 for the Tarkwa and Peru cash-generating units relating to impairments raised in prior years and concluded that no impairment reversals are required. 3 On 12 December 2025, Gold Fields entered into agreements to sell a portfolio of royalty assets for a total cash consideration of US$115.0 million and its right to the Asanko deferred and contingent considerations for US$30.0 million and US$22.0 million, respectively. Certain assets within the royalty portfolio, having a combined value of US$77.5 million, 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$77.5 million 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. A fair value gain of US$77.5 million was recognised in profit or loss. 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$37.5 million or the deferred and contingent considerations were highly probable and therefore they were not recognised as held for sale. Refer note 17. 4 At 31 December 2024, the investment in O3 Mining was presented as an asset held for sale as Gold Fields entered into the lock-up agreement with Agnico Eagle before 31 December 2024. On 24 January 2025, Agnico Eagle acquired 110,424,431 common shares of O3 Mining, which included the Gold Fields owned shares, representing approximately 94.1% of the outstanding common shares.

Notes to the condensed consolidated financial statements continued 12. Acquisition of Gold Road Background On 13 December 2016, Gold Fields purchased 50% of the Gruyere Gold Project and entered into a 50:50 unincorporated joint operation with Gold Road Resources Limited (“Gold Road”) for the development and operation of the Gruyere Gold Project in Western Australia, which comprises the Gruyere gold deposit as well as additional resources including Central Bore and Attila/Alaric. On 5 May 2025, Gold Fields entered into an agreement to acquire 100% of the issued and outstanding share capital of Gold Road. This represents a direct acquisition of Gold Road, as well as an indirect acquisition of the remaining 50% interest in the Gruyere Gold Project (the “second Transaction”). The acquisition date was 26 September 2025, the date on which all conditions precedent were met and control of Gold Road was obtained. Recognition and measurement Gold Fields and Gold Road previously had joint control over the Gruyere Gold Project. Accordingly, the Group classified its interest in the project as a joint operation. When a joint operation is acquired through stages that results in control of an entity that is a business, the transaction is treated as a business combination achieved in stages. On 26 September 2025, the previously held 50% interest in the Gruyere Gold Project was remeasured to its fair value and the resulting gain was recognised in profit or loss. The fair value of the previously held 50% interest was included as part of the total cost of the operation and recognised as a business combination together with the additional 50% interest held by Gold Road, in terms of the second Transaction. Consideration The following summarises the consideration for the business combination at 26 September 2025: Figures in millions unless otherwise stated United States Dollar Australian Dollar (a) Fixed cash consideration 1,490.3 2,276.5 (b) Variable cash consideration 702.0 1,072.3 (c) Fair value of previously held interest in joint operation 1,197.9 1,829.8 (d) Add: Special dividend 312.6 477.5 Total purchase consideration 3,702.8 5,656.1 (a) Fixed cash consideration The US$1,490.3 million (A$2,276.5 million) cash represents the fixed cash consideration of US$1,802.9 million (A$2,754.0 million) paid for 1,092,838,545 Gold Road shares at a purchase price of A$2.52 per share, less the US$312.6 million (A$477.5 million) special dividend of A$0.43694 per Gold Road share. The special dividend was declared by the Gold Road Board on 16 September 2025 and was payable to Gold Road shareholders. The final fixed consideration portion amounted to A$2.08306 per Gold Road share. (b) Variable cash consideration The US$702.0 million (A$1,072.3 million) cash represents the variable cash consideration paid for 1,092,838,545 shares at the purchase price of A$0.98117 per Gold Road share in an all-cash transaction. This reflects the shareholders proportionate value of Gold Road's shareholdings in Northern Star Resources Ltd (“Northern Star”). The purchase price of A$0.98117 was determined by the weighted average price of Northern Star shares during the five trading days up to and including 25 September 2025. (c) Previously held interest in joint operation The US$1,197.9 million (A$1,829.8 million) represents the fair value of the previously held 50% interest in joint operation derecognised at 26 September 2025 and recognised as a business combination together with the additional 50% interest held by Gold Road. The fair value of the previously held 50% interest was based on its fair value less cost of disposal "FVLCOD") calculated using a combination of the market (resource value) and the income approach. Refer the next page for assumptions used in the valuation.

Revenue and profit after taxation of the acquiree (Gold Road) from 26 September 2025 to 31 December 2025 amounted to US$151.3 million and US$49.0 million, respectively. Revenue and profit after taxation (as if the acquisition was completed at the beginning of the year) of the combined entity (Gold Fields Group, Gold Road and Gold Road acquisition PPA adjustments) for the year ended 31 December 2025 amounted to US$9,111.0 million and US$3,747.6 million, respectively. At 31 December 2025, total assets (excluding deferred taxation) for the Gruyere segment amounted to US$3,514.9 million (2024: US$541.1 million) and total liabilities (excluding deferred taxation) amounted to US$265.7 million (2024: US$233.7 million). The Australian operations are entitled to transfer and offset profits and losses from one company to another, therefore it is not meaningful to disclosure the deferred taxation for Gruyere separately.

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 years ended 31 December 2025 and 31 December 2024.

Investments – listed Comprise equity investments in listed entities and therefore valued using quoted market prices in active markets. Royalties - asset held for sale 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 11 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. 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 mainly listed bonds that are measured at amortised cost which approximates fair value. The fair value is determined using quoted market prices in active markets. Borrowings The 10-year notes and 7-year notes (2024: 5-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. 36 Gold Fields Reviewed Results 2025

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$37.5 million or the deferred and contingent considerations were highly probable 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.

Gold production decreased by 6% to 73,400 ounces in the December quarter from 78,000 ounces in the September quarter due to a 5% reduction in tonnes milled following a planned shutdown in December 2025. AIC increased by 17% to A$3,451/oz (US$2,242/oz) in the December quarter from A$2,951/oz (US$1,924/oz) in the September quarter due to lower gold sales and higher capital and operating expenditure associated with production-enabling activities, inclusive of mining contractor variation payments, implementation of a full fleet management system (Wenco) and essential fixed plant maintenance at the Gruyere Process Plant. Capital expenditure increased by 106% to A$105m (US$69m) in the December quarter, compared with A$51m (US$33m) in the September quarter following recognition of Gruyere cost profile post- acquisition at 100%. In addition, A$7m (US$5m) was spent on Stage 6 of the Gruyere tailings facility during the December quarter. Gold Fields Reviewed Results 2025 47

As at 31 December 2025, stockpiled ore totalled 89,000 tonnes at an average grade of 5.3g/t, containing approximately 15,100 ounces. AIC increased by 34% to A$2,852/oz (US$1,870/oz) in the December quarter from A$2,121/oz (US$1,384/ oz) in the September quarter mainly due to lower gold sales and higher capital expenditure. Total capital expenditure increased by 42% to A$59m (US$38m) in the December quarter from A$41m (US$27m) in the September quarter, mainly due to increased mine development, expenditure on camp accommodation upgrades and increased expenditure on the new mine fresh air intake system to support the Z135 and Z150 extraction levels. 48 Gold Fields Reviewed Results 2025

Lower production cost and lower capital expenditure resulted in an 8% decrease in AIC to A$3,284/oz (US$2,151/oz) in the December quarter from A$3,562/oz (US$2,317/oz) in the September quarter. The lower production cost reflects the completion of mining activities at the Swiftsure open pit in the September quarter, together with reduced operational waste mining at the Invincible open pit in the December quarter. Total capital expenditure decreased by 7% to A$118m (US$78m) in the December quarter from A$127m (US$83m) in the September quarter mainly due to lower expenditure on the renewable power project of A$44m (US$29m) in the December quarter (September quarter – A$69m/ US$45m), partially offset by increased pre-strip mined at the new Santa Ana open pit and expenditure on the Invincible material handling study in the December quarter.

Total tonnes mined decreased by 10%, from 522kt in September quarter to 468kt in the December quarter, primarily due to fewer production shifts caused by planned maintenance on shaft infrastructure. This reduction also impacted gold mined, which decreased by 11% to 2,375 kg (76.3Koz) from 2,655kg (85.4Koz) in the previous quarter. Similarly, ore tonnes milled from underground decreased by 7%, dropping from 420kt in September quarter to 389kt in the December quarter. AIC R/kg increased by 8% to R1,107,991/kg (US$1,998/oz) mainly due to lower gold sold in Q4 and higher capital expenditure, which was partially offset by lower cost of sales before amortisation and depreciation. Capital expenditure increased by 34% to R779m (US$45m) in the December 2025 quarter from R583m (US$33m) in the September 2025 quarter. The main expenditure items relate to an increase in acquisition of trackless equipment, shaft rehabilitation, shaft infrastructure maintenance (winder) and electrical reticulation.

Independent Auditor’s Review Report On Condensed Consolidated Financial Statements To the Shareholders of Gold Fields Limited We have reviewed the condensed consolidated financial statements of Gold Fields Limited, set out on pages 20 to 39, which comprise the condensed consolidated statement of financial position as at 31 December 2025 and the related condensed consolidated income statement and condensed consolidated statements of comprehensive income, changes in equity and cash flows for the year then ended, and selected explanatory notes. Directors’ Responsibility for the Condensed Consolidated Financial Statements The directors are responsible for the preparation and presentation of these condensed consolidated financial statements in accordance with the requirements of the JSE Limited Listings Requirements for condensed financial statements, as set out in the “Basis of preparation” note on page 20 to the financial statements, and the requirements of the Companies Act of South Africa, and for such internal control as the directors determine is necessary to enable the preparation of condensed consolidated financial statements that are free from material misstatement, whether due to fraud or error. Auditor’s Responsibility Our responsibility is to express a conclusion on these condensed consolidated financial statements. We conducted our review in accordance with International Standard on Review Engagements (ISRE) 2410, which applies to a review of historical financial information performed by the independent auditor of the entity. ISRE 2410 requires us to conclude whether anything has come to our attention that causes us to believe that the condensed consolidated financial statements are not prepared in all material respects in accordance with the applicable financial reporting framework. This standard also requires us to comply with relevant ethical requirements. A review of condensed consolidated financial statements in accordance with ISRE 2410 is a limited assurance engagement. We perform procedures, primarily consisting of making inquiries of management and others within the entity, as appropriate, and applying analytical procedures, and evaluate the evidence obtained. The procedures performed in a review are substantially less than those performed in an audit conducted in accordance with International Standards on Auditing. Accordingly, we do not express an audit opinion on these condensed consolidated financial statements. Conclusion Based on our review, nothing has come to our attention that causes us to believe that the condensed consolidated financial statements of Gold Fields Limited for the year ended 31 December 2025 are not prepared, in all material respects, in accordance with the requirements of the JSE Limited Listings Requirements for condensed financial statements, as set out in “Basis of preparation” note on page 20 to the financial statements, and the requirements of the Companies Act of South Africa. Other Matter This review report does not address the “Pro Forma Financial Information” or non IFRS measures presented with the condensed consolidated financial statements and accordingly, these are not included in our review conclusion.

Independent Auditor’s Assurance Report on the compilation of pro forma financial information for the year ended 31 December 2025 included in the Gold Fields Limited Reviewed Results 2025 To the Directors of Gold Fields Limited We have completed our assurance engagement to report on the compilation of the pro forma financial information of Gold Fields Limited (the “Company”) (and its subsidiaries (together “the Group”)) by the directors. The pro forma financial information, as set out in the “Gold Fields Limited Reviewed Results 2025” for the year ended 31 December 2025 comprises certain non-IFRS financial measures (the “Pro Forma Financial Information”). The applicable criteria on the basis of which the directors have compiled the Pro Forma Financial Information are specified in the Listings Requirements of the JSE Limited (“the JSE Listings Requirements”) and described in the Gold Fields Limited Reviewed Results 2025 (the “Applicable Criteria”). The Pro Forma Financial Information has been compiled by the directors solely to provide users with relevant information and measures used by the Group to assess performance. As part of this process, information about the Group’s financial position and financial performance has been extracted by the directors from the Group’s condensed consolidated financial statements for the year ended 31 December 2025, on which a review opinion was issued. Directors' responsibility for the Pro Forma Financial Information The directors are responsible for compiling the Pro Forma Financial Information on the basis of the Applicable Criteria. Our Independence and Quality Management We have complied with the independence and other ethical requirements of the Code of Professional Conduct for Registered Auditors, issued by the Independent Regulatory Board for Auditors’ (IRBA Code), which is founded on fundamental principles of integrity, objectivity, professional competence and due care, confidentiality and professional behaviour. The IRBA Code is consistent with the corresponding sections of the International Ethics Standards Board for Accountants’ International Code of Ethics for Professional Accountants (including International Independence Standards). The firm applies International Standard on Quality Management 1, Quality Management for Firms that Perform Audits or Reviews of Financial Statements, or Other Assurance or Related Services Engagements, which requires the firm to design, implement and operate a system of quality management, including policies or procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements. Auditor’s responsibility Our responsibility is to express an opinion, as required by the JSE Listings Requirements, about whether the Pro Forma Financial Information has been compiled, in all material respects, by the directors, on the basis of the Applicable Criteria, based on our procedures performed. We conducted our engagement in accordance with the International Standard on Assurance Engagements (ISAE) 3420, Assurance Engagements to Report on the Compilation of Pro Forma Financial Information Included in a Prospectus issued by the International Auditing and Assurance Standards Board. This standard requires that we plan and perform our procedures to obtain reasonable assurance about whether the Pro Forma Financial Information has been compiled, in all material respects, on the basis specified in the Applicable Criteria. For purposes of this engagement, we are not responsible for updating or reissuing any reports or opinions on any historical financial information used in compiling the Pro Forma Financial Information, nor have we, in the course of this engagement, performed an audit or review of the financial information used in compiling the Pro Forma Financial Information. The purpose of the Pro Forma Financial Information included in the Gold Fields Limited Reviewed Results 2025 is solely to provide users with relevant information and measures used by the Group to assess performance. A reasonable assurance engagement to report on whether the Pro Forma Financial Information has been compiled, in all material respects, on the basis of the Applicable Criteria involves performing procedures to assess whether the Applicable Criteria used by the directors in the compilation of the Pro Forma Financial Information provide a reasonable basis for presenting the significant effects directly attributable to the events, and to obtain sufficient appropriate evidence about whether: • The related pro forma adjustments give appropriate effect to those criteria; and • The Pro Forma Financial Information reflects the proper application of those adjustments to the unadjusted financial information. The procedures selected depend on our judgement, having regard to our understanding of the nature of the Group, the events in respect of which the Pro Forma Financial Information has been compiled, and other relevant engagement circumstances. Our engagement also involves evaluating the overall presentation of the Pro Forma Financial Information. We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. Opinion In our opinion, the Pro Forma Financial Information has been compiled, in all material respects, on the basis of the Applicable Criteria. PricewaterhouseCoopers Inc.

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 2024 filed with the Johannesburg Stock Exchange and the Annual Report on Form 20-F filed with the United States SEC on 27 March 2025 (SEC File no. 001-31318).
