Statement by Mike Fraser, CEO Tragically we had to report two fatalities in the first six months of this year (H1 2024). We again extend our deepest condolences to the families and loves ones of our deceased colleagues. Our operational performance was disappointing with attributable production declining by 20% due to unplanned events, the delayed ramp-up at Salares Norte and the backfill issues at South Deep. In line with our dividend policy of paying out between 30% - 45% of normalised profit as dividends, we are pleased to declare an interim dividend of 300 SA cents per share (40% of normalised earnings) (H1 2023: 325 SA cents per share or 35% of normalised earnings). I am confident of an improved performance in the second half of the year as we implement enhancements to our safety processes and systems, progress ramp up of Salares Norte and realise the benefits of operational recovery plans under way at South Deep, Gruyere, St Ives and Cerro Corona. Our portfolio of quality assets is operated and managed by talented and dedicated teams and our focus remains on setting up these assets to deliver safe, reliable and cost-effective production, sustainably. Our asset optimisation initiatives and improvements in organisational capability further support the focus on safe, cost-effective and reliable operating performance. From 1 July 2024 we implemented a redesigned operating model, moving from a three-layered (Group, region, asset) structure to a two- layered (Group, asset), function-led operating model, which will enable safe and reliable portfolio performance. The new operating model also provides more agility as our portfolio evolves to enable the delivery of our strategy. Through continued investments in our existing assets, bolt-on acquisitions and exploration we are confident of further improving the quality of our portfolio. Health & safety The safety and wellbeing of our people remains our number one value, and it is with deep regret that two of our colleagues lost their lives whilst working at our operations in H1 2024. As previously reported, a trackless engineering supervisor was fatally injured at South Deep in January in an incident involving trackless mining equipment underground. A second incident occurred at the St Ives mine in April 2024, when a colleague employed by a contractor was fatally injured in a mobile equipment related incident at a construction site on the mine. We extend our deepest condolences to the family, friends and colleagues of our two deceased colleagues. I absolutely believe that a fatality-free mining business is possible and that we can deliver on our promise that everyone who works at Gold Fields goes home safe and healthy, every day. In February 2024, we commissioned DSS+ (formerly Du Pont) to conduct an independent review of the group’s safety culture, processes, systems and practices. The review found many good practices within the Group, including pockets of excellence that we are seeking to leverage across our global assets. The review, however, also highlighted areas where improvement is clearly required. On the basis of the review, we have developed and are implementing our multi-year safety improvement roadmap. Operational performance Group performance in H1 2024 was impacted by weather-related events and operational challenges at some of our assets. As a result, attributable gold production was 20% lower year-on-year (YoY) to 918koz (H1 2023: 1,154koz). 918,000oz attributable production US$1,745/oz all-in sustaining costs US$2,060/oz all-in costs US$355m normalised earnings* US$321m adjusted free cash flow from operations US$58m adjusted free cash outflow** 300 SA cents interim dividend per share * Profit excluding gains and losses on foreign exchange, financial instruments and non- recurring items after taxation and non-controlling interest effect ** Cash flow from operating activities less net capital expenditure, environmental payments, lease payments and redemption of Asanko preference shares. JOHANNESBURG, 23 August 2024: Gold Fields Limited (NYSE & JSE: GFI) announced profit attributable to owners of the parent for the six months ended 30 June 2024 of US$389m (US$0.43 per share). This compared with profit of US$458m (US$0.51 per share) for the six months ended 30 June 2023. A gross interim dividend of 300 SA cents per share is payable on 16 September 2024. Unaudited interim results for the six months ended 30 June 2024

The lower volumes significantly impacted unit costs with all-in costs (AIC) increasing by 47% YoY to US$2,060/oz (H1 2023: US$1,398/oz) and all-in sustaining cost (AISC) increasing by 44% YoY to US$1,745/oz (H1 2023: US$1,215/oz). Both AIC and AISC are forecast to improve in H2 2024 with the delivery of higher volumes. Granny Smith and Agnew in Australia and Tarkwa and Damang in Ghana were the stand-out performers in the Group, delivering on their operational plans during the first half of the year. Lower Group production was driven by: • South Deep, where increased backfill rehandling and challenging ground conditions impacted stope access, stope turnaround, planned volumes and grade profile • Gruyere, following a significant rainfall event in H1 2024 that saw mining and processing operations suspended for approximately six weeks • St Ives, which had planned for a lower first half production but was further impacted by a delay in the development of two new open pits at the mine, Swiftsure and Invincible Footwall South. Consequently, St Ives is planning a stronger, second half production performance; • Cerro Corona, which experienced inclement weather in Q1 2024 affecting the stability of the North wall of the pit, resulting in a resequencing of mining to lower grade areas. The stability of the North wall has been addressed. The copper-gold price ratio also impacted the gold-equivalent production performance • Slower than planned ramp-up at Salares Norte due to the early onset of winter and a difficult ramp-up in the winter period. Salares Norte update In June 2024, we announced that early onset of severe winter weather conditions had impacted ramp-up at Salares Norte leading to freezing of material in the process plant pipes and causing temporary shutdown of the plant. Ramp-up was therefore temporarily suspended and production guidance revised to 90koz – 180koz. Over the past few months, we have been working on progressing all activities required for the plant restart, including thawing of frozen material, and unblocking of plant piping. Salares Norte continued to experience low temperatures which has slowed down progress on these activities. We are currently focused on setting up the plant for a safe and sustainable restart and ramp up. We expect to complete all adverse weather mitigation activities (including heat tracing installation) by the first quarter of next year. This should ensure safe and continuous operations through winter conditions, in line with the design criteria of the plant. The plant is scheduled to restart by 30 September 2024 and deliver production of 40koz - 50koz in 2024. Any unforeseen delays to this restart date will impact production volumes for 2024. Total project costs (excluding capitalised borrowing costs) for Salares Norte up to 30 June 2024 were US$1,176m, within the guided range of US1,180m - US$1,200m. Additional capital costs associated with the project include capitalised borrowing costs, capitalised depreciation and ramp-up capital totalling US$190m to 30 June 2024. Ramp-up capital is expected to increase following the delays in the ramp-up. Sustaining capital for Salares Norte for H1 2024 was approximately US$58m for mining activities. Despite the delays in ramp up, Salares Norte remains a high-quality asset that will have one of the industry's lower cost profiles. It is expected to contribute meaningfully to our future cash flows and is value accretive to Gold Fields. The chinchilla capture and relocation plan remains suspended for Rocky Area 3 at Salares Norte, while the regulator examines the requested evidence of chinchilla presence at the rockery. Gold Fields has not undertaken any capture and relocation activities during the winter months at Salares Norte, with the programme planned to resume thereafter in close collaboration with environmental experts and the regulator. South Deep update South Deep produced 3,633kg (117koz) in H1 2024 compared to 4,743kg (152koz) in the comparative period. Lower production was due to backfill rehandling challenges and poor ground conditions. Backfill seepage constrained access to stopes, while the backfill rehandling added complexity to the planning and mining process. This had an impact on stope turnaround and delayed access to the higher grade areas of the mine. South Deep is making progress accelerating backfill placement to address the historic backfill leakage and is assessing various solutions to reduce backfill leakages going forward. Other recovery activities are focused on improving long hole stope drilling and overall productivity. Having thoroughly assessed the recovery trajectory for South Deep for the remainder of the year, we are revising 2024 production guidance from 9,500kg – 9,700kg (305koz – 312koz) to 7,800kg - 8,200kg (250koz - 264koz) to set up the mine for an improved 2025 performance. Lower volumes will impact unit costs with all-in costs (AIC) and all-in sustaining costs (AISC) guidance for 2024 revised to US$1,890/ oz - US$1,980/oz, respectively. With its significant resource endowment and long life, improvement measures are focused on being sustainable so that the mine is set up for longevity and quality ounces. Financial performance Normalised earnings for the six months ended June 2024 decreased by 22% YoY to US$355m, or US$0.40 per share (H1 2023: US$454m, or US$0.51 per share), mainly driven by a higher gold price received which was more than offset by lower gold sold. During H1 2024, there was an adjusted free cash outflow of US$58m (after taking into account all costs and project capex), compared to an inflow of US$140m in H1 2023. The mines generated adjusted free cash flow from operations of US$321m in H1 2024 compared to US$482m in H1 2023. While our balance sheet remains robust, with a net debt to EBITDA ratio of 0.53x at the end of June 2024, our net debt increased by US$129m during H1 2024 to US$1,153m. This increase was driven by US$42m in Windfall pre-construction capital and the US$199m final dividend payment. Excluding lease liabilities, the core net debt was US$720m at the end of H1 2024. In May 2024, Gold Fields repaid its US$500m 2024 bond using a combination of cash and undrawn facilities. At the end of June 2024, the Group’s capital structure consisted of a US$1.2bn sustainability linked revolving credit facility (US$534m of which was undrawn), a US$500m bond which matures in 2029 and US$528m in cash. ESG highlights During H1 2024, we continued to progress our ESG priority areas. In terms of gender diversity, the number of women among our employees remained at 25% at the half year, with over 57% of these women working in core mining roles. Our female representation at executive level is 33%. With a focus on community value creation, it is pleasing to note that over half of our workforce (52%) lives in our host communities, while the Company sourced 40% of its H1 2024 procurement from companies based in these communities. On 7 August 2024, our St Ives mine signed a landmark native title agreement with the Ngadju People, who are the determined native title holders of the lands and waters surrounding Norseman, which spans approximately 102,000km2 and includes the St Ives mine. The agreement will see significant value delivered to the Ngadju People over the life-of-mine through compensation payments and other initiatives and benefits, including an initial payment in recognition of historical mining activities that have occurred on Ngadju lands, as well as providing comprehensive processes for the identification and preservation of Aboriginal cultural heritage sites. We continued to make strides in our decarbonisation journey, with renewable energy accounting for 17,1% of electricity consumption at Group level for the six months under review. Scope 1 and 2 CO₂ emissions during H1 2024 declined by 6.2% below 2023 levels. However, due to lower gold production, emission intensity per oz produced was 19% higher than in 2023. Construction of the following renewable plants has commenced: • Granny Smith: 11 MW solar farm and 7MW battery expansion, to be commissioned in Q4 2024; • St Ives: 35MW solar farm and 42MW wind, to start in Q1 2026; • Salares Norte: 7MW solar farm, to be commissioned in Q1 2025. 2 Gold Fields H1 Results 2024

We have commenced with a mid-term review of our 2030 ESG targets across our six priority areas, namely safety wellbeing and environment; gender diversity; stakeholder value creation; decarbonisation; tailings management; and water stewardship. As well as assessing our performance against our existing targets, the review will consider potential changes to existing priorities, and what is required to extend our targets out to 2035. The findings and outcomes of the review will be published in early 2025. Board and executive appointments We are pleased to have made a number of crucial leadership appointments since the beginning of the year, including the appointment of Martin Preece as COO, Mariette Steyn as EVP Sustainable Development and Chris Gratias as EVP Strategy and Corporate Development. We have made good progress on the appointment of a permanent CFO, to replace Paul Schmidt who retired at the end of April 2024, An announcement on this appointment will be made imminently. Alex Dall will continue as interim CFO until the permanent CFO is appointed. At Board level, we announced the appointment of two non-executive directors with effect from 2 August 2024. Shannon McCrae, a Canadian, who brings 25 years of experience in the resources industry, and South African Zarina Bassa, who adds extensive corporate and regulatory accounting experience and who is also joining the Board’s Audit Committee. These appointments strengthen the Board’s capacity to oversee the increasingly complex operating and regulatory environment facing global mining companies. The way forward: Continuing to improve the quality of our portfolio Gold Fields has a well-established, portfolio of mines that is expected to produce over 2.2Moz per annum for the next decade. This portfolio is anchored by four long-life assets – St Ives, Tarkwa, South Deep and Windfall – which all have significant Reserve endowments and are expected to form base production for multiple decades. These assets are complemented by Agnew and Granny Smith in Australia which are two of our most consistent producers and will continue to contribute into the next decade. Although Gruyere has had a tough start to 2024, operational momentum is improving, and it will continue to be a valuable contributor until at least the end of the decade. Salares Norte, once ramped up, will contribute a significant cash windfall for at least 3 – 4 years. We are undertaking extensive exploration drilling to identify opportunities to extend the Salares Norte life of mine and are on track to spend approximately US$23m on exploration drilling in the area during 2024. Our strategy is premised on continually upgrading and improving the quality of our production base. This not only entails acquiring assets that will enhance the quality of the portfolio, but also disposing of assets which we view as non-core and do not fit with our long-term vision. During H1 2024, we streamlined our portfolio by selling equity stakes and holdings in assets that we believe were better served in other companies’ hands. In January, we sold our 24% interest in Rusoro Mining for an upfront consideration of US$62m. We also concluded the sale of our 45% stake in the Asanko Gold Mine in March for gross proceeds of US$170m, comprised of US$65m in cash, three deferred cash payments and a 19.9% shareholding in Galiano. After the close of the Q2 trading period, we finalised the sale of our 40% stake and terminated our option agreement to buy an additional 20% in the Far Southeast asset in the Philippines. While the asset had been fully impaired in Gold Fields’ books, we received an upfront payment of US$1m together with a US$10m contingent consideration. While Damang continues to contribute healthy cash flow to the Group, we continue to assess our options for the asset. Although there a sizeable Resource below the current Damang Pit, a further cutback will entail material capital investment and we do not believe that this is the most optimal use of our capital. As such, we are exploring alternative options for the asset but will only do so in a responsible and sustainable manner. Cerro Corona is also maturing, with 2025 being the last year of mining before the mine only processes stockpiles from 2026 onwards. While it will continue to produce gold and generate cash flow until 2031, we have begun to consider options for Cerro Corona’s future. Gold Fields has a healthy pipeline of attractive growth opportunities which will enhance the quality of the overall portfolio by lowering average AIC and increasing the free cash-flow generation of the business. Osisko acquisition On 12 August 2024 we announced the acquisition of all the Osisko Mining shares for C$4.90 per share or transaction consideration of approximately C$2.2bn (US$1.6bn and enterprise value of C$1.5bn (US$1.1bn). The acquisition consolidates the Gold Fields’ interest in a world-class, advanced-stage project that we understand well, having jointly owned the asset with Osisko since May 2023. With assets situated in Québec, Canada, Gold Fields will firmly solidify its presence in this Tier-1 mining jurisdiction in one of the largest gold deposits in Canada, and a top ten gold deposit globally by head grade. Full ownership of Windfall enables us to streamline decision-making and increase flexibility with respect to the project’s development and subsequent operation. Based on Osisko’s December 2022 feasibility study, Windfall is expected to produce circa 300,000 ounces per annum at an all-in sustaining cost of below US$800 per ounce (2023 real terms). Our technical and project development work over the last year has progressed our understanding of the asset and confirms our view that Windfall is expected to become one of the lowest cost mines in our portfolio. We believe that Windfall is on track to become our next high-quality, low- cost underground gold mine, with considerable growth prospects along strike and down plunge, well beyond delineated mineral reserves and the current 10-year projected mine life set out in Osisko’s Windfall Feasibility Study. The highly prospective Urban Barry and Quévillon district exploration camps (circa 2,233km2), is anticipated to provide a range of additional opportunities beyond the scope of the Windfall Feasibility Study. Development of Windfall is well advanced. As at May 2023 (when we announced the joint venture partnership with Osisko), Osisko had invested more than C$800m in Windfall. Since then, the partners (through their respective 50% shares) have each invested an additional ~C$158m (total of ~C$316m) on the development of the Project. As a result, Windfall today includes over two million meters of drilling, a submitted Environmental Impact Assessment permitting application in process, studies, significant underground development and major surface infrastructure. The Project is now under its fourth bulk sample permit, with underground infrastructure including 14km of underground development to 671 metres of vertical depth into ore, four main ventilation raises and 57 drill bays, an underground pumping station and a garage currently under construction. Concurrently, extensive surface civil works have already been undertaken, including a lined waste pad, three lined water treatment ponds, a water treatment facility currently under construction, administrative offices, communication tower, temporary 300-person camp, and recreation area. Environmental permitting for full scale construction of the Project is underway, with a new round of questions recently received from the Québec Ministry of the Environment, and final approval expected in 2025. In parallel, discussions have continued towards the execution of an Impact and Benefit Agreement with the Cree First Nation of Waswanipi and the Cree Nation Government in due course, as part of the project development process. During January 2024, the 85 km long 69 kV hydro-electric power line - built, owned and operated by the Waswanipi Cree First Nation - was completed on schedule, and grid power was successfully connected to the Project. This will significantly reduce both power costs and greenhouse gas emissions at the site. Tarkwa/Iduapriem JV In March 2023, Gold Fields announced the proposed joint venture between Tarkwa and AngloGold Ashanti’s neighbouring Iduapriem mine in Ghana. In addition to leveraging operating efficiencies to unlock higher grades and enabling an extension of life to at least 18 years, the proposed joint venture is expected to create compelling shared value for all stakeholders. Since the announcement, Gold Fields and AngloGold Ashanti have had extensive engagement with the Government of Ghana with respect to the proposed transaction. While significant progress has been made, final Parliamentary approval has not yet been finalised. We continue to Gold Fields H1 Results 2024 3

actively pursue completion of the joint venture and will keep the market updated with any developments in this regard. Exploration Exploration plays an important role in Gold Fields’ strategy of continually enhancing the quality of our production base. It ensures the longevity of our business by providing a pipeline of attractive opportunities that will potentially be brought into production in the longer term. Our greenfields exploration strategy focuses on targeted expansion within our current operational jurisdictions while continuously screening for new opportunities in select areas based on strict criteria. Our strategies include 100% acquisition, JV earn-in arrangements and equity partnerships. Our greenfields budget is US$40m, with approximately US$9.4m spent in H1. The Group’s greenfields exploration portfolio includes 100% landholdings and joint ventures in Australia, Chile, and Peru, all advancing through early-stage exploration activities, permitting, and access agreements. We also hold strategic positions in several junior exploration companies, including Tesoro Gold (18.9%), Chakana Copper (18.4%), Torq Resources (15.0%), Hamelin Gold (14.9%), Killi Resources (10.9%) and Great Southern Mining (4.6%). Notable highlights in H1 2024 include participating in Chakana Copper’s capital raise (US$0.62m) to fund a maiden drill test of the Mega Gold target, with results pending. Additionally, we announced an option and joint venture on Killi Resources' West Tanami project in Western Australia, where Gold Fields may earn an 85% interest through expenditure of US$8.6m over seven years, including a US$0.33m investment in the company. We have also commenced our earn-in at the Edinburgh Park project in Queensland, making good progress with land access and geophysical programmes. In August, Torq Resources announced a proposed US$48m earn-in option and joint venture agreement with Gold Fields to advance the exploration and development of Torq’s Santa Cecilia copper-gold project in Chile. Under the agreement, Gold Fields is to be granted a two-stage option to acquire up to a 75% interest in the Santa Cecilia Project in exchange for spending US$48m in spending over a maximum of six years. Gold Fields has also entered into three option and joint venture agreements with Gold & Copper Resources to earn up to an 80% interest in three separate areas of the Orange gold project in New South Wales, Australia. Gold Fields must initially spend a minimum of A$9m over three years across the three areas, with rights to earn up to 75% in any or all of the projects by sole funding commitments over 7-8 years (and an additional 5% for funding certain study work). During H2 2024, Gold Fields will continue generative activities, including screening third-party opportunities in Australia, West Africa, and the Americas. Capital allocation framework Capital allocation is a key element of Gold Fields’ strategic decision- making process. In this regard, we have refined our capital allocation framework to guide how capital is deployed and ensure the most attractive return on this capital. In terms of this framework, our capital allocation priorities are as follows: • Maintaining our investment grade credit rating • Spending the necessary capital to ensure safe and reliable production • Paying a base dividend. Gold Fields has a dividend policy of paying out 30% - 45% of normalised earnings. After satisfying the above capital allocation priorities, discretionary growth investments need to compete with additional returns to shareholders. Discretionary growth investments could include exploration, life extension of existing assets, organic growth opportunities and inorganic M&A opportunities. 2024 production and cost guidance Given the operational headwinds experienced in H1 2024, we are reducing 2024 guidance. There will be a significant increase in production during H2 2024, with attributable gold equivalent production expected to be between 1.11Moz - 1.21Moz for the six-month period. Consequently, H2 2024 unit costs are expected be lower than those reported for H1 2024, with AISC forecast of US$1,460/oz – US$1,580/oz and AIC set to be US$1,630/oz – US$1,750/oz for the second half. Taking the second half guidance into account, Group attributable gold equivalent production for 2024 is now expected to be between 2.05Moz - 2.15Moz, with the decrease from previous guidance primarily driven by South Deep and Cerro Corona which has been negatively impacted by the copper price factor. Given the relatively slow progress made with the Salares Norte ramp-up during the winter months, we now expect the mine to produce between 40koz-eq - 50koz-eq in 2024, which has also contributed to the reduced Group guidance. Group AISC is expected to be between US$1,580/oz - US$1,670/oz while AIC is guided to be between US$1,820/oz - US$1,910/oz for the year. These include approximately US$30/oz for the 2024 capital expenditure on the St Ives renewable energy project. Excluding the costs for this project, the range for AISC is US$1,550/oz – US$1,640/oz and US$1,790oz - US$1,880/oz for AIC.

Results for the Group Six months ended 30 June 2024 compared with six months ended 30 June 2023 Health and safety During H1 2023 Gold Fields experience two operational fatalities (FY 2023: 2) and two serious injuries (2023: 6) during H1 2024. On 2 January 2024, a trackless engineering supervisor was fatally injured in an incident involving trackless mining equipment underground at our South Deep mine in South Africa. A second fatal incident occurred at our St Ives mine in Australia on 23 April 2024, when a colleague was fatally injured in a mobile equipment related incident at a construction site on the mine. We again extend our sincere condolences to the family, friends and colleagues of our two deceased colleagues. As a result of our continued failure to eliminate fatal incidents, we commissioned DSS+ (formerly Du Pont) to carry out an independent review of the Group’s safety culture, processes, systems and practices. The high-level findings of the study are discussed in the CEO Report. The study revealed challenges regarding psychological safety of our people as well as wider mental health issues. Addressing these challenges aligns closely with the recommendations arising from the Respectful Workplace review we carried out among our workforce during 2023. We are continuing to implement the 24 recommendations put together by our teams and EB&Co, the consultancy that carried out the Respectful Workplace review. We have already implemented policy changes to strengthen diversity and eliminate discrimination, bullying, harassment and other undesirable behaviours at our offices and mines. Year ended Safety H1 2024 FY 2023 H1 2023 Fatalities 2 2 1 Serious injuries1 2 6 3 1 A Serious Injury is a work-related injury that incurs 14 days or more of work lost and results in a range of injuries detailed at goldfields.com/safety.php Environmental No serious (level 3–5) environmental incidents were reported for H1 2024, continuing the trend of preceding years. We last incurred a serious environmental incident in 2018. The Group has two water-related targets for 2030, focusing on proactive water management and efficiency and enhanced engagement with catchment stakeholders. Performance remains on track to meet these targets: • H1 2024 water recycled/reused was 73% (H1 2023: 71%). Targets: 2024: 75%; 2030: 80% • H1 freshwater withdrawal was 6.1 GL (H1 2023: 5.3 GL). Targets: FY 2024: 11.8 GL; 2030: 8.00 GL Water use is subject to seasonal variation and is usually high in H1 2024 YTD freshwater withdrawal was higher due to a heavy rainfall event at Granny Smith improving their water quality classification to fresh water. The additional water has significant advantages as use of rainwater does not impact aquifers and alleviates future strain on borefields. Group energy spend was US$212m (20% of operating costs) and US$209/oz for H1 2024 compared to US$405m (19% of operating costs) and US$163/oz in 2023, reflecting slightly higher fuel prices and lower gold production. Group energy use was 7.0 petajoules (PJ), compared to 6.9 PJ for same period last year, or 14.0 PJ for FY2023. Scope 1 and 2 CO₂e emissions were 0.8Mt, consistent with H1 2023 or 1.6 Mt for FY2023. The main reason for the deterioration in emissions intensity was lower gold production despite constant tonnes mined and processed. Renewables accounted for 17.3% (2023: 17.2%) of electricity consumption at Group level during H1 2024, with renewables providing 50% of electricity consumed by our Agnew mine in Australia and 17% of South Deep’s electricity consumption. Wind trials and an Environmental Impact Assessment continue at South Deep. Construction of the US$195m renewables project at St Ives in Australia commenced and, once commissioned, will add impetus in our drive to reduce our scope 1 and 2 emissions. In line with our 2020 commitment, we published the GISTM reports for our high-priority dams at the Tarkwa and Cerro Corona mines on 4 August 2023 and are on track to publish the GISTM reports for our remaining active facilities by August 2025. The Salares Norte chinchilla rescue and relocation plan was approved by the regulator in June 2023. Implementation of the three year plan commenced in late 2023. In May, Salares Norte received a directive (MUT) from Chile’s environmental regulator (SMA) requesting additional information and ordering temporary suspension of the dismantling of Rocky Area No 3. No relocation activities have been, or are planned to be, carried out during the winter months (until September). The MUT was extended to October 2024. Salares Norte is working with the SMA and independent environmental experts to ensure alignment on the programme.

Gold Fields aims to sustain the value delivered to host communities through employment, procurement and social investments. The Group host community workforce was 9,373 people – 52% of the total workforce (excluding projects and corporate offices) for H1 2024 compared to 8,031, 45% of the total workforce, in H1 2023. Group host community procurement spend in H1 2024 was US$527m (41% of total spend), compared to US$427m (33% of total) for the same period in 2023. In total, value creation to host communities amounted to US$601m in H1 2024, 35% of national value creation (H1 2023: US$498m; 31%). Our 2030 target is 30% of total national value creation. The Group has an approved pipeline of legacy programmes that will positively impact host communities beyond the life-of-mine. Implementation of two programmes has started. Our total workforce as at 30 June was approximately 20,200 (including projects and corporate offices), comprising 31% employees and 69% contractors, which is a similar distribution as in 2023. Women comprised 25% of Gold Fields’ employees at the end of H1 2024, compared to 22% for H1 2023 and 25% for FY 2023. Currently, women occupy 27% of our leadership rolls and 57% of our female employees work in core mining activities. Gold Fields H1 Results 2024 7

Post quarter-end Gold Fields announced two significant events that put substance to our Purpose statement of “creating enduring value beyond mining”. On 7 August, Gold Fields and the Ngadju Native Title Aboriginal Corporation announced the signing of an historic Native Title Agreement for the St Ives mine in Australia. The Ngadju People are the determined Native Title holders of the area surrounding Norseman, spanning 102,000km2, which includes sections of the St Ives tenement. It will see significant value delivered to the Ngadju People through compensation payments and other initiatives and benefits, including a substantial initial payment in recognition of the historical mining activities that have occurred on Ngadju lands. A key focus of the agreement is the protection and management of cultural heritage. Gold Fields will also guarantee entry-level positions for Ngadju people and prioritise prioritise Ngadju employment and procurement. On 16 August, the Gold Fields Ghana Foundation handed over the newly constructed and refurbished Tarkwa & Abosso (T&A) Stadium in Tarkwa to the National Sports Authority. The rehabilitation work on the T&A Stadium started in January 2020 and was completed in June this year at a cost of US$16.2m - this makes it one of Gold Fields’ largest infrastructure investment projects to date. This investment transformed the 400-seat football park into an 8,000- plus seater world-class stadium, capable of hosting international matches. The contractors building the stadium employed 924 people from Tarkwa and surrounding communities in the construction of the stadium. The Foundation, which receives funding from Gold Fields Ghana’s Tarkwa and Damang mines, has spent over US$100m over the past two decades to ensure sustainable socio-economic development in host communities and strengthen Gold Fields’ social licence to operate.

Processing primarily of low-grade stockpiles continued until 28 March 2024 when a lack of reagents resulted in the closure of the mill. Open pit mining operations were also temporarily discontinued during this time due to a lack of diesel. This resulted in a reduction of waste stripping, ore mined and processed when compared to the six months ended 30 June 2023 with consequential reductions in gold produced and increases in AIC/oz. Gold production decreased by 20% to 126,900oz for H1 2024 from 158,700oz in H1 2023, mainly due to lower volumes of ore mined and processed. AIC increased by 62% to A$2,676/oz (US$1,762/oz) in H1 2024 from A$1,648/oz (US$1,114/oz) in H1 2023, mainly due to lower gold sold and higher capital expenditure. Total capital expenditure (on a 50% basis) was 106% higher for the period at A$55m (US$36m) from A$27m (US$18min H1 2023 due increased capital waste mined. Despite the lower production, Gruyere generated adjusted pre-tax free cash flow of A$55m (US$36m) (50% basis) during H1 2024 compared to A$89m (US$60m) in H1 2023 driven by the increased gold price received during the period. Guidance Guidance remains unchanged for 2024 as provided in February 2024 as follows: • Gold produced ~ 150,000oz - 167,500oz (50%); • Sustaining capital expenditure ~ A$122m (US$81m) - A$130m (US$86m) (50%); • Non-sustaining capital expenditure ~ nil (50%); • AISC ~ A$2,060/oz (US$1,360/oz) - A$2,290/oz - (US$1,510/oz) and • Total AIC ~ A$2,080/oz (US$1,370/oz) - A$2,310/oz (US$1,525/oz).

AIC increased by 11% to A$2,124/oz (US$1,399/oz) in H1 2024 from A$1,913/oz (US$1,293/oz) H1 2023 due to lower gold sales and inflationary pressures on commodity inputs and employee and contractor costs. Total capital expenditure increased by 2% to A$64m (US$42m) for the period from A$63m (US$42m) in H1 2023. Adjusted pre-tax free cash flow for Granny Smith increased by 107% to A$200m (US$132m) in H1 2024 from A$97m (US$65m) in H1 2023, mainly due to the higher gold price realised. 12 Gold Fields H1 Results 2024

This was in line with the mine plan for the year. Open pit volumes and associated grades are expected to improve during H2 2024 as the Swiftsure and Invincible Footwall South open pits start contributing to the mining mix. As a result, production at St Ives is anticipated to increase materially during the second half of the year. AIC increased by 64% to A$3,041/oz (US$2,003/oz) in H1 2024 from A$1,858/oz (US$1,256/oz) in H1 2023 due to a gold-in-process draw- down following processing of surface stockpiles, increased capital expenditure and lower gold sales. AISC and AIC are expected to reduce as volumes increase in H2 2024. Total capital expenditure increased by 73% to A$124m (US$82m) in H1 2024 from A$72m (US$49m) in the previous period due to development of the Swiftsure and Invincible Footwall South open pits, and expenditure on the Renewables Power Project. These two open pits will move into ore production during the second half of 2024. Adjusted pre-tax free cash flow at St Ives decreased by 81% to A$26m (US$17m) in H1 2024 from A$133m (US$90m) in H1 2023. This was as a result of lower gold sold and higher capital expenditure, partially offset by a higher gold price received. Guidance Guidance remains unchanged for 2024 as provided in February 2024 as follows: • Gold produced ~ 355,000oz; • Sustaining capital expenditure ~ A$358m (US$236m); • Non-sustaining capital expenditure ~ A$43m (US$28m); • AISC ~ A$2,721/oz (US$1,796/oz); and • Total AIC ~ A$2,900/oz (US$1,913/oz). Excluding the renewable microgrid project, the 2024 AISC guidance is A$2,153/oz (US$1,421/oz) and the 2024 AIC guidance is A$2,331/oz (US$1,538/oz). Gold Fields H1 Results 2024 13

AIC increased by 12% to A$2,282/oz (US$1,503/oz) for the period from A$2,038/oz (US$1,377/oz) in H1 2023 due to increased production cost following higher underground ore production and increased capital expenditure. Total capital expenditure increased by 5% to A$57m (US$38m) in H1 2024 from A$55m (US$37m) in the previous period due to the commencement of the Barren Lands / Redeemer decline and associated capital works in establishing this new underground mine. Adjusted pre-tax free cash flow for Agnew increased by 47% to A$128m (US$84m) in H1 2024 from A$87m (US$59m) in H1 2023, mainly due to the higher gold price realised.

access owing to increased backfill rehandling and slow drilling through crushed ground resulting in slower stope turnaround in current destress cuts. The mine has developed and implemented a recovery plan to address this which is being closely monitored. Gold produced decreased by 25% to 3,633kg (116,800oz) in H1 2024 from 4,841kg (155,700oz) in H1 2023. The reduction is largely driven by increased off reef development to access new destress cuts. Improved gold contribution from destress cuts is expected in the second half of the year as on reef development increases. AIC was 41% higher to R1,147,032kg (US$1,906/oz) for H1 2024 from R811,816/kg (US$1,387/oz) in H1 2023, mainly due to the lower gold sold and higher capital expenditure. Total capital expenditure increased by 25% to R824m (US$44m) for the period from R659m (US$36m) in H1 2023, mainly due to the old return water dam upgrade, TM3 refurbishments and Collision Avoidance System (CAS) level 9 rollout. Adjusted free cash flow decreased by 67% to R587m (US$31m) for H1 2024 from R1,759m (US$97m) in H1 2023. The decrease is mainly due to lower gold sold and higher capital expenditure, partially offset by a higher gold price received. Guidance The guidance for South Deep has been revised further from what was announced on 13 June 2024 (9,500kg – 9,700kg) as follows: • Gold production for 2024 is now expected to be in the range of 7,800kg – 8,200kg, with the mine’s AISC and AIC for 2024 expected to be in the range of US$1,890/oz – US$1,980/oz.

A total of 2,476kt ore was fed from the stockpile for H1 2024 at a grade of 0.93g/t compared with 1,002kt at a grade of 1.12g/t from stockpile and 1,384kt at a grade of 1.17g/t from ex-pit in H1 2023. AIC increased by 56% to US$1,917/oz in H1 2024 from US$1,230/oz in H1 2023 due to lower gold sold, higher capital expenditure and higher cost of sales before amortisation and depreciation. Cost of sales before depreciation and amortisation increased by 53% to US$119m in H1 2024 from US$80m in the previous period mainly due to higher GIP charge. GIP charge was US$57m in H1 2024, compared with GIP credit of US$19m in H1 2023. Total capital expenditure increased by 34% to US$5m in H1 2024 from US$4m in H1 2023 mainly due to timing of the Far East Tailings Storage Facility raise project. Despite the higher AIC, which was largely driven by the non-cash GIP charge of treating stockpiles, Damang generated adjusted free cash flow of US$62m in H1 2024 which was 241% higher than the US$18m in H1 2023. Guidance Guidance remains unchanged for 2024 as provided in February 2024 as follows: • Gold produced ~ 125,000oz; • Sustaining capital expenditure ~ US$5m; • Non-sustaining capital expenditure ~ Nil; • AISC ~ US$2,030/oz; and • Total AIC ~ US$2,030/oz.

As a result, total waste tonnes mined increased by 16% to 40.0Mt in H1 2024 from 34.5Mt in the previous period. Ore tonnes mined decreased by 31% to 6.9Mt from 10Mt in H1 2023 and this resulted in the additional lower grade stockpiles processed as mentioned above to fill the mill during H1. As a result, gold production at Tarkwa is expected to increase in H2 2024 when compared to H1 2024 as the higher grade material from the Akontansi and Kotraverchy pits are added to the mining mix. Gold production decreased by 14% to 247,700oz in H1 2024 from 287,700oz in H1 2023 due to lower yield. Yield decreased by 18% to 1.05g/t in the period from 1.28g/t in H1 2023 due to lower grade fed. Ore processed from stockpile was 2.35Mt at a grade of 0.79g/t in H1 2024 Gold Fields H1 Results 2024 15

compared to 0.46Mt at a grade of 1.20g/t in H1 2023 while ex-pit ore processed was 5.0Mt at a grade of 1.28g/t in the period compared to 6.5Mt at 1.34g/in H1 2023. AIC increased by 54% to US$1,822/oz in H1 2024 from US$1,181/oz in H1 2023 due to lower gold sold and higher cost of sales before amortisation and depreciation which were partially offset by lower capital expenditure. The higher cost of sales before amortisation and depreciation was mainly due the 14% increase in operational tonnes mined to 28.1Mt in H1 2024 from 24.6Mt in H1 2023 and a gold inventory charge to cost of US$51m for the period compared to a gold inventory credit to cost of US$44m in H1 2023. Total capital expenditure decreased by 8% to US$112m H1 2024 from US$122m in H1 2023 mainly due to lower spend on TSF construction. Adjusted free cash flow for Tarkwa was 47% lower at US$52m in H1 2024 from US$98m in H1 2023, mainly due to lower gold sold, partially offset by the higher gold price realised. Guidance Guidance remains unchanged for 2024 as provided in February 2024 as follows: • Gold produced ~ 540,000oz; • Sustaining capital expenditure ~ US$167m; • AISC ~ US$1,480/oz; and • Total AIC ~ US$1,480/oz.

Control of the operation was handed over from the project team to the operational team. Ramp-up of the project has been negatively impacted by the early onset of winter events which have persisted. These weather events resulted in the freezing of material in the piping of the process plant causing a temporary shutdown of the plant. These impacts have been greater than planned owing to the early onset and extended duration of winter conditions during the commissioning and ramp-up phase. We are currently focused on setting up the plant for a safe and sustainable ramp up. We expect to complete all adverse weather mitigation activities (including heat tracing installation) by the first quarter of next year, in order to ensure safe and continuous operations through winter conditions, in line with the design criteria of the plant. The plant is expected to restart by 30 September 2024 and deliver production of 40koz - 50koz in 2024. Any unforeseen delays to this plant restart date will impact production volumes for 2024. Gold and silver production in H1 2024 was 487oz Au and 2,475 oz Ag respectively, resulting in gold-equivalent production of 517oz for H1 2024. Total AIC in H1 2024 was US$500,923/oz. Total capital expenditure increased by 28% to US$230m for the period from US$180m in H1 2023. The higher capital expenditure was mainly due to prioritising Salares Norte Project construction and completion activities (pre-commissioning and commissioning). Adjusted free cash outflow for Salares Norte increased by 27% to US$256m in H1 2024 from US$202m in H1 2023 mainly as a result of the higher capital expenditure. Guidance Given the relatively slow progress made with the Salares Norte ramp-up during the winter months, we now expect the mine to produce between 40koz eq - 50koz eq. 16 Gold Fields H1 Results 2024

Grades are expected to increase during H2 2024 as mining returns to the higher grade areas of the pit which will drive a material improvement in production during the second half. Gold production decreased by 48% to 37,000oz in H1 2024 from 70,900oz in H1 2023 and copper production decreased by 29% to 10,078t for the period from 14,267t in H1 2023. In both cases, the decrease was mainly due to lower yield as a result of lower head grades processed combined with lower throughput due to ore hardness. Consequently, total equivalent gold production decreased by 42% to 78,500oz in H1 2024 from 135,300oz in H1 2023. AIC per gold ounce increased by 197% to US$911/oz in H1 2024 from US$307/oz in H1 2023, mainly due to lower gold sold and lower by- product credits for the period as a result of lower copper sold partially offset by lower capital expenditure. Total capital expenditure decreased by 49% to US$10m in H1 2024 from US$20m in H1 2023, due to the completion of the TSF construction in 2023. Adjusted free cash flow for Cerro Corona decreased by 79% to US$15m in H1 2024 from US$71m in H1 2023, mainly due to lower gold-equivalent ounces sold, partially offset by the higher gold and copper prices realised. Guidance The estimate for 2024 is revised as follows: • Gold equivalents produced ~ 177,000 oz (original guidance 197,000 oz); • Gold produced ~91,300 oz (original guidance 96,900 oz); • Copper tonnes produced ~ 21,800 t (original guidance 24,185 t); • Copper price ~ US$9,080 per tonne (original guidance US$8,500 per tonne); • Gold price ~ US$2,310/oz (original guidance US$2,050/oz); • AISC ~ US$1,515/eq oz (original guidance US$1,230/eq oz); • Total AIC ~ US$1,590/eq oz (original guidance US$1,310/eq oz); • AISC ~ US$870/oz (original guidance US$585/oz); and • Total AIC ~ US$1,010/oz (original guidance US$735/oz).

Corporate announcements PIC acquires over 20% shareholding in Gold Fields On 18 June 2023 Gold Fields Gold Fields Limited has received formal notification that the Public Investment Corporation SOC Limited (PIC) has, in aggregate, acquired an interest in the ordinary shares of the company, such that the total interest in the ordinary shares of the Company held by PIC now amounts to 20.099% of the total issued ordinary shares of the company. This makes the PIC, which among others oversees the investments of the South African Government Employee Pension Fund, the largest shareholder in Gold Fields. Revision to Salares Norte and Group 2024 guidance On 13 June 2023, Gold Fields reported that the ramp-up at the Salares Norte Project had been further negatively impacted by the early onset of winter events which have persisted in recent weeks. These weather events resulted in the freezing of material in the piping of the process plant causing temporary shutdown of the plant. These impacts have been greater than planned owing to the early onset and extended duration of winter conditions during the commissioning and ramp-up phase. The plant has been restarted, however, commissioning and ramp-up during the winter period are expected to continue to be challenging, creating uncertainty on production levels during the winter months. Calendar year 2024 production guidance for the Project is therefore being revised down from the previously indicated gold-equivalent ounces range of 220koz – 240koz, to 90koz – 180koz. The bottom end of this range (90koz) is largely independent of weather events until late August 2024 and assumes the following for ramp-up from now until the end of 2024: • No production until the end of the winter period with testing of sub-systems only until end of August 2024. • Ramp-up resumes on 1 September 2024. • No significant weather events resulting in multiday stoppages from September 2024 onwards (weather-related downtime is considered in the ramp-up factor). • Circuit C commissioning continues from September 2024 onwards, with this circuit fully operational by mid-October 2024. • Conservative metallurgical recoveries. The top end of the range (180koz) assumes the following for ramp-up from now until the end of 2024: • Ramp-up resumes on 15 June 2024. • No significant weather events that result in multi-day stoppages for the rest of 2024 (weather-related downtime is considered in the ramp-up factor) • Circuit C commissioning continues from July 2024 onwards with this circuit fully operational by August 2024. • Conservative metallurgical recoveries. The design criteria of the plant will be capable of handling such winter weather events at steady state and total Project capital costs remain in line with guidance of US$1,180m - US$1,200m. Due to the Salares Norte production revision, Gold Fields is revising 2024 Group production guidance from 2.33Moz - 2.43Moz to 2.20Moz – 2.30Moz. All-in costs (AIC) for the group in 2024 are revised from the US$1,600/oz – US$1,650/oz range previously guided to US$1,675/oz – US$1,740/oz, while guidance for all-in sustaining costs (AISC) is revised to US$1,470/oz – US$1,530/oz (compared to US$1,410/oz – US$1,460/oz previously guided). Update on Salares Norte chinchilla capture and relocation plan On 17 May 2024, Gold Fields advised shareholders that Salares Norte had received an urgent and transitionary measure (MUT) from Chile’s Superintendence of Environment (SMA) ordering temporary suspension of the dismantling of Rocky Area No 3 (R3) as part of its approved Chinchilla rescue and relocation plan. On 5 June 2024, Salares Norte received an updated notice from the SMA extending the suspension of dismantling R3 for a further 120 days. Mining operations and project activities are continuing, and the focus remains on ramp-up of the project, respecting the buffer zones established to avoid any potential disturbance to this species and complying with all other regulatory requirements established by the authority. As part of the initial MUT issued on 14 May 2024, the SMA requested additional information detailing the monitoring activities undertaken at R3. Salares Norte submitted this information which included endoscopic probe search and night camera recordings. Gold Fields continues to engage with the SMA to progress the Chinchilla capture and relocation plan. In accordance with the approved capture and relocation plan, Gold Fields is not planning to undertake any capture and relocation activities during the winter months at Salares Norte. The Company remains committed to the safe capture and relocation of the protected Chinchilla species and Salares Norte continues to work with the SMA and independent environmental experts on all aspects of this programme.

During the periods ended 30 June 2024 and 2023, the Gold Fields Limited 2012 Share Plan as amended in 2016 was in place. At the Annual General Meeting on 18 May 2016, shareholders approved the adoption of the revised Gold Fields Limited 2012 Share Plan to replace the long-term incentive scheme (LTIP). The plan provides for four types of participation, namely Performance Shares (PS), Retention Shares (RS), Restricted Shares (RSS) and Matching Shares (MS). This plan is in place to attract, retain, motivate and reward participating employees on a basis which seeks to align the interests of such employees with those of the Company’s shareholders. 2 Senior and middle management receive awards under the LTIP. The performance conditions of the LTIP are approved annually by the Remuneration Committee. The expected timing of the cash outflows in respect of each grant is at the end of three years after the original award was made. 3 Included under "Other costs, net" in the consolidated income statement. 4 The Mineral and Petroleum Resource Royalty Act 2008 (Royalty Act) was promulgated on 24 November 2008 and became effective from 1 March 2010. 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 period ended 30 June 2024 was 0.5% of mining revenue (2023: 0.5%) equalling the minimum charge per the formula. 5 The Australian operations are subject to a 2.5% (2023: 2.5%) gold royalty on revenue as the mineral rights are owned by the state. 6 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% 7 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 H1 Results 2024

Mining and income taxation The components of mining and income tax are the following: South African taxation – Company and capital gains taxation (1.3) (3.8) – non-mining taxation (0.2) (0.2) – deferred taxation (32.6) (33.9) Foreign taxation – current taxation (151.6) (239.9) – prior year adjustment – current taxation1 (12.3) — – deferred taxation (41.0) 12.2 Dividend withholding tax (7.7) (9.0) Total mining and income taxation (246.7) (274.6) South Africa – current tax rates Mining tax2 Y=33-165/X Y=33-165/X Non-mining tax3 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% 1 The US$12.3m in 2024 relates to additional transfer pricing tax at Tarkwa. 2 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 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% (2023: 28%). 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. 3 Non-mining income of South African mining operations consists primarily of interest income. The corporate income tax rate was reduced from 28% to 27% for tax years ending on after 31 March 2023 and was effective for the period ended 30 June 2023. 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 H1 Results 2024 29

Acquisition of Windfall Project Background On 2 May 2023, Gold Fields, through a 100% held Canadian subsidiary, acquired a 50% interest in the Windfall Project in Québec, Canada, which is in the feasibility stage, from Osisko Mining Incorporated (the Partnership). • Under the partnership structure, each of Osisko Mining Incorporated (Osisko) and Gold Fields, respectively, hold an effective 50% partnership interest in the Windfall Project and the Exploration Properties; and • The management company (responsible for the operation) will be governed by a Board of Directors comprising three directors nominated by Gold Fields and three directors nominated by Osisko. Decisions over the relevant activities of the partnership requires unanimous consent of both the parties. Recognition and measurement Gold Fields and Osisko have joint control over the Windfall Project, the transaction is structured as a separate vehicle and the Group has a residual interest in the net assets of the Windfall Project. Accordingly, the Group has classified its interest in the Windfall Project as a joint venture. Consideration The following summarises the consideration and the cost of the Windfall joint venture: United States Dollar Canadian Dollar United States Dollar Canadian Dollar Figures in millions unless otherwise stated June 2024 June 2024 Dec 2023 Dec 2023 Carrying value at 1 January 538.6 713.6 — — Initial recognition Cash considerations Purchase of equity-accounted investee — — 247.1 333.8 (a) C$300.0m cash payment — — 221.5 300.0 (b) Pre-closing paid amounts – C$16.9m — — 12.8 16.9 – C$16.9m — — 12.8 16.9 Contingent and exploration considerations (c) C$300.0m contingent consideration - initial fair value — — 190.8 258.4 (d) C$75.0m exploration consideration - initial present value — — 39.1 52.9 Subsequent measurement Cash considerations (e) Capital contributions 42.4 57.5 69.1 93.0 Contingent and exploration considerations (c) C$300.0m contingent consideration - net change in fair value1 3.7 5.0 7.3 9.9 (d) C$75.0m exploration consideration - unwinding of discount rate1 2.2 3.0 2.9 3.9 Share of loss (30.5) (41.4) (28.4) (38.3) Translation adjustment (16.6) — 10.7 — Carrying value at the end of the period 539.8 737.7 538.6 713.6 1 The movements were recognised as part of the equity investment. (a) C$300m cash payment The US$221.5m (C$300.0m) cash payment represents the initial consideration paid on 2 May 2023 for the 50% interest in the joint venture. (b) Pre-closing paid amounts Osisko acquired certain assets for the benefit of the Windfall Project during the term sheet negotiation stage. Gold Fields agreed to refund Osisko 50% of the costs spent on these items in two equal payments of US$12.8m (C$16.9m) on 31 July 2023 and US$12.8 m (C$16.9m) on 31 December 2023, respectively. (c) C$300m contingent consideration The C$300.0m contingent consideration is payable on issuance of an EIA permit to the Partnership authorising the construction and operation of the Windfall Project.

Notes to the condensed consolidated financial statements continued 18. 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 2024 and year ended 31 December 2023. 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 2024 31 December 2023 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 12.9 — 12.9 — 18.2 — 18.2 — Investments – listed 125.0 125.0 — — 65.8 65.8 — — Asanko redeemable preference shares — — — — 99.7 — — 99.7 Financial assets not measured at fair value Environmental trust funds 115.4 — 115.4 — 109.6 — 109.6 — Financial liabilities measured at fair value Windfall Project - contingent consideration 199.9 — — 199.9 202.5 — — 202.5 Financial liabilities not measured at fair value Borrowings 1,256.8 507.3 — 749.5 1,249.9 1,010.5 — 239.4 Environmental trust funds The environmental trust funds are measured at fair value through profit or loss and amortised cost which approximates fair value based on the nature of the fund's underlying investments. 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. Asanko redeemable preference shares The fair value is based on the expected cash flows of the Asanko Gold Mine based on the life-of-mine model. The key inputs used in the valuation of the fair value at 31 December 2023 were the market related discount rate of 19.9% and the expected redemption period. The movement in the preference shares was as a result of fair value adjustments only. Borrowings The 10-year notes (2023: 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. Windfall Project - contingent consideration The fair values are based on the expected cash flows of the respective considerations. The key inputs used in the valuation of the fair value were the approval period, probability factor and discount rate. 38 Gold Fields H1 Results 2024

Total development increased by 9% in the June quarter to 3,206m from 2,934m in the March quarter as improved efficiencies were realised from HP drill rigs owing to maturing cuts and increased end availability. Total tonnes mined in the June quarter increased by 23% to 544kt from 444kt in the March quarter. Improved volumes were driven by additional equipment coming into production, improved equipment reliability, utilisation and by improvements in the mining efficiencies. Reef grade mined increased by 5% to 5.53g/t in the June quarter from 5.25g/t in the March quarter driven by the changing mining footprint. Backfill placed increased by 40% to 153,382m3 in the June quarter from 109,663m3 in the March quarter as stopes became available for backfilling. Total underground tonnes milled increased by 13% to 471kt in the June quarter from 415kt in the March quarter due to increased mining volumes. Surface tonnes processed decreased by 10% to 282kt in the June quarter from 314kt in the March quarter due to lower operating hours as a result of planned maintenance of a CIL tank. Reef yield decreased by 17% to 4.28g/t in the June quarter from 5.13g/t in the March quarter due to a lower-than-planned mine call factor (MCF). Surface yield decreased by 29% to 0.10g/t in the June quarter from 0.14g/t in the March quarter as high-grade surface clean-up material was depleted, the current yields are in line with the business plan. AIC remained flat at R1,149,439/kg (US$1,924/oz) in the June quarter from R1,144,350/kg (US$1,886/oz) in the March quarter. Total capital expenditure increased by 42% to R483m (US$26m) in the June quarter from R341m (US$18m) in the March quarter. The increase is mainly due to higher mobile equipment refurbishments, Collision Avoidance System (CAS) level 9 implementation on underground mobile equipment, higher spend on underground fixed infrastructure (roadways, waste rock aggregate plant, tips), purchasing of underground steel handling equipment and annual Microsoft licencing in the June quarter.

Waste stripping to unlock ore increased and key ore blocks are expected to be exposed in Q3 2024. Total tonnes mined, including capital waste stripping, increased by 9% due to increased mining capacity and to prioritise waste stripping to unlock key ore blocks. AIC increased by 8% to US$1,897/oz in the June quarter from US$1,751/ oz in the March quarter due to lower gold sold, higher royalties and higher capital expenditure. Total capital expenditure increased by 6% to US$58m in the June quarter from US$54m in the March quarter due to higher tailings project construction expenditure of US$9m in the June quarter compared to US$5m in the March quarter.

AIC per gold ounce sold decreased by 40% to US$672/oz in the June quarter from US$1,116/oz in the March quarter, mainly due to higher by- product credit resulting from a higher copper price and a higher gold inventory credit to cost on the back of the higher low-grade ore mined and stockpiled during the dry season. This was partially offset by lower gold ounces sold. Total capital expenditure decreased by 15% to US$5m in the June quarter from US$6m in the March quarter, driven by the TSF Water Treatment Plant construction plan. Gold Fields H1 Results 2024 53
