JOHANNESBURG, 23 February 2023: Gold Fields Limited (NYSE & JSE: GFI) announced profit attributable to owners of the parent for the year ended 31 December 2022 of US$711m (US$0.80 per share). This compared with profit of US$789m (US$0.89per share) for the year ended 31 December 2021. A final dividend number 97 of 445 SA cents per share (gross) is payable on 20 March 2023, giving a total dividend for the year ended 31 December 2022 of 745 SA cents per share (gross). I would like to reiterate that Gold Fields remains in a strong position, with high-quality near-term production growth that sets us apart from our global peers. In addition, we have a disciplined capital allocation framework, focusing on maintaining a strong balance sheet; returning cash to shareholders; investing in our business; and seeking appropriate value accretive external opportunities. Our strategy remains centred around the three pillars that we communicated towards the end of 2021, namely: • Pillar 1: Maximise the potential of our current assets through people and innovation • Pillar 2: Build on our leading commitment to ESG • Pillar 3: Grow the value and quality of our portfolio of assets The Yamana transaction addressed pillar 3 and in that context I believe it would have been a composite solution to address the longer term challenges facing Gold Fields and the gold sector in general. However, it was not the only option that Gold Fields considered when assessing our strategic options. We will continue to conduct analysis on the alternatives, which, to the extent that they involve potential M&A, are more focused on incremental growth and/or regional, rather than transformational, transactions. Gold Fields has a solid production base underpinned by our Australian region which is expected to produce c.1Moz pa for at least the next 10 years. Tarkwa is another cornerstone asset for the Group and is expected to produce c.500koz. We have strong production growth from 2024 onwards with the completion and ramp-up of Salares Norte (to 500koz) and continued build-up at South Deep (to 380koz). However, there are assets in the portfolio which are maturing and reaching the end of their lives. 2022 was the last year of steady state production at Damang post the reinvestment in the pit cutback. In 2023, production from Damang will come from a combination of ore from the Huni pit and stockpiles, with only stockpiles being treated from 2024 onwards. Cerro Corona will continue to operate at current levels until 2025, after which the level of production will drop significantly as it will also start only processing stockpiles. This lower level of production will continue until the end of the decade which is when the mine is currently scheduled to comes to an end. Gold Fields has limited organic growth opportunities in our current portfolio and as such will need to pursue inorganic opportunities to bolster our pipeline. These options will include greenfields targets, development projects or bolt-on acquisitions of producing assets. 2022 was an eventful year for Gold Fields, dominated by the Yamana transaction, which we terminated following a competing bid. I have stepped in as interim CEO, after the resignation of Chris Griffith in December 2022. My first commitment to our People is that of Zero Harm. Our concept of Zero Harm does not only cover physical injuries and health, but also includes the psychological well-being of our People. I will work with our teams across the globe to ensure that we achieve this.

Greenfields will potentially include exploration in targeted jurisdictions as well as taking minority stakes in exploration companies like we have done with Chakana Copper in Peru and more recently with Torq Resources and Tesoro Gold in Chile. Despite the Yamana transaction occupying a significant amount of senior corporate management’s time and attention during last year, Gold Fields exceeded the upper end of its 2022 guidance which remained unchanged throughout 2022. This bears testament to the stability of our operating regions and the great work being done by our exceptional people running our assets. Our balance sheet remains healthy and has been bolstered by the Yamana break fee, providing us with increased flexibility. Gold Fields finished 2022 with net debt of US$704m, resulting in a net debt to EBITDA ratio of 0.29x. I want to reiterate our commitment to shareholder returns. The enhanced dividend policy that we announced in July 2022 remains in place, Gold Fields commits to pay out between 30% and 45% of normalised earnings from 2023 onwards. Recognising the windfall we received from the break fee together with our strong financial performance, we declare a final 2022 dividend of 445 SA cents per share. This takes the total dividend declared for the year to 745 SA cents per share which represents a payout ratio of 47% of normalised earnings. Our focus for 2023 remains on delivering first gold at Salares Norte and then building up towards full production in 2024. Indications are that there will be a potential further three month delay in the start up of production, with first gold now expected in Q4 2023. As previously communicated, COVID-19 and severe weather conditions during the winter months have caused the initial delay, with ongoing skills sourcing challenges faced by the main contractor at Salares Norte in the latter part of 2022 and start of 2023 resulting in the further delay. Despite the delay, Salares Norte remains a world class asset which will deliver average annual production from 2024 to 2029 of 500koz at AISC of US$660/oz (in 2023 terms). Health and safety In October, we tragically suffered a fatal incident at our underground Hamlet mine at St Ives in Western Australia. A raise bore operator succumbed to injuries in a rock fall. This was the first fatality we have recorded in Australia since we started operating there in 2001. On 5 February 2023, there were two fatal injuries at the Asanko mine in Ghana, which is managed by Galiano Gold. The two contractor employees were involved in a vehicle incident at the mine. My heartfelt condolences go out to the family, friends and colleagues of our deceased colleagues. We are pleased to report that South Deep had a fatality-free year for the first time since Gold Fields acquired the mine in 2006. This is a significant milestone for the mine and reflects years of unwavering commitment to implementing sound safety processes, systems and standards and working with our people and organised labour to develop the right safety culture. The Group-wide TRIFR improved to 2.04 per million hours worked from 2.16 in 2021, while the number of serious injuries declined from nine in 2021 to five in 2022. The COVID-19 pandemic had a minimal impact on operations during 2022. We continue to roll-out vaccination to our employees and recorded no COVID-19 related fatalities last year and minimal hospitalisations. In the previous two years, 20 of our colleagues had passed away as a result of contracting the virus. Our concept of Zero Harm does not only cover physical injuries and health, but also includes the psychological well-being of our People, particularly creating workplaces that are safe for women and free from sexual harassment and bullying. An external review into gender safety at our offices and operations is currently being undertaken by a reputable consultancy, whose findings are expected in Q2 2023 and will subsequently be reviewed by management and the Board and a detailed response plan developed and implemented. This is particularly important as we strive to build an inclusive and diverse workforce that represents the full demographics of the countries and communities we operate in. We continue to make progress with gender equality and at the end of 2022, 23% of total employees were women, up from 22% a year earlier and on track to achieve the 30% target by 2030. Results for FY 2022 Attributable gold equivalent production for 2022 was 2,399koz, a 3% increase YoY (FY2021: 2,340koz), exceeding the guidance range of 2,310koz – 2,360koz. The Group all-in sustaining and all-in cost were below the guidance provided in February 2022. All-in sustaining costs (AISC) for the year were US$1,105/oz (FY2021: US$1,063/oz), lower than the guidance range of between US$1,140/oz and US$1,180/oz, mainly due to weaker exchange rates. AISC, if adjusted to 2022 guidance exchange rates (R/US$15.55 and US$/A$0.76) was US$1,160/oz, which is well within the guidance range. All-in cost (AIC) for 2022 was US$1,320/oz, higher than 2021 mainly due to high mining cost inflation (FY2021: US$1,297/oz) and below the lower end of the guidance range of US$1,370/oz – US$1,410/oz, as a result of lower than planned capex at Salares Norte and weaker exchange rates. AIC, if adjusted to 2022 guidance exchange rates is US$1,381/oz, was also within the guidance range. The average Rand/US Dollar exchange rate weakened by 11% to R16.37 in 2022 from R14.79 in 2021. The average US Dollar/Australian Dollar exchange rate weakened by 8% to US$0.69 from US$0.75. Basic earnings for 2022 decreased by 10% YoY to US$711m or US$0.80 per share (2021: US$789m or US$0.89 per share). Headline earnings for 2022 increased 19% YoY to US$1,061bn or US$1.19 per share (2021: US$890m or US$1.00 per share). Normalised earnings for the year were 7% lower YoY at US$860m or US$0.97 per share (2021: US$929m or US$1.05 per share). Gold Fields recognised several impairments at year-end which were driven by an increase in discount rates together with inflationary cost pressures experienced in 2022. The biggest impairments recognised at year-end comprises: • Tarkwa: US$325m pre-tax (US$220m post-tax) mainly due to the increase in the discount rate from 8.3% to 15.9% as a result of increases in the Ghana country risk premium and the risk free rate. • Cerro Corona: US$63m pre-tax (US$44m post-tax) mainly due to the increase in the discount rate from 4.8% to 8.1% as a result of increases in the risk-free rate. • Far South East: US$114m – the investment has been written down to a carrying value of nil. Despite our old dividend policy having a payout ratio of 25% to 35% of normalised earnings, we declared a final dividend of 445 SA cents per share, which represents a 47% payout ratio. This takes the total dividend declared for the year to 745 SA cents per share (FY2021: 470 SA cents per share). Despite 2022 being a higher capital expenditure year for Gold Fields, the Group generated adjusted free cash flow of US$431m (FY2021: US$463m). Adjusted free cash flow from the operations for the year, which excludes project capital, was US$855m compared to the US$913m generated in 2021. During 2022, there was a US$265m decrease in the net debt, ending the year at US$704m, with a net debt to adjusted EBITDA ratio of 0.29x. This compares with a net debt balance of US$969m and a net debt to adjusted EBITDA ratio of 0.40x at the end of December 2021. Excluding lease liabilities, the core net debt was US$310m at the end of FY2022. ESG Gold Fields’ performance against our key 2030 ESG targets, which importantly includes eliminating serious injuries and fatalities is covered on pages 7 – 8 of this results book. We are on track to achieve our 2030 targets and have detailed strategies and supporting plans to get us there. Noteworthy is that net carbon emissions in 2022 were still 1% higher against our 2016 baseline. However, this is as per our schedule and we are on track to achieve the 30% reduction by 2030, particularly as we continue to roll-out renewable energy projects at our mines. Construction of the R715m, 50MW Khanyisa solar plant at South Deep in South Africa was completed within budget. The plant was successfully commissioned and is currently being optimised. 2 2022Gold Fields Reviewed Results

Despite some delays, the 12MW Gruyere solar plant was also successfully commissioned within budget of US$20m in 2022. Electricity from renewables accounted for 13% the Group’s total consumption in 2022, with renewables providing 54% of electricity consumed by our Agnew mine in Australia and the hydro electricity supply to our Cerro Corona mine in Peru certified 100% renewable. Regional overview Australia Gold Fields’ Australian operations delivered another strong operational performance in 2022, once again surpassing the 1Moz annual production level. Gold production increased by 4% to 1,061koz in 2022 from 1,019koz in 2021. All-in cost increased by 9% to A$1,659/oz (US$1,150/oz) in 2022 from A$1,526/oz (US$1,146/oz) in 2021. The Australia region generated adjusted free cash flow of US$431m in 2022, 7% lower than the US$466m generated in 2021. South Africa South Deep continued to show pleasing operational improvements during 2022, with gold production increasing 12% to 10,200kg (328koz) in 2022 from 9,102kg (293koz) in 2021. Total all-in cost increased by 9% to R713,624/kg (US$1,356/oz) in 2022 from R655,826/kg (US$1,379/oz) in 2021, with the prevailing inflationary pressures and higher capital costs partially offset by higher gold sales. South Deep in early February 2023 also concluded a two year extension to its current three-year wage agreement with organised labour. This agreement seeks to balance the interest of the Company and employees and brings much needed certainty and stability to the operation until 2026. Encouragingly, adjusted free cash flow increased by 47% to R2.1bn (US$129m) in 2022 from R1.4bn (US$97m) in 2021. This is the fourth consecutive year of positive free cash flow from the mine. The feasibility study on South of Wrench is progressing with indications that initial development will begin in the latter part of 2023. Ghana Total managed production decreased by 4% to 838koz in 2022 from 871koz in 2021, primarily driven by the decreased production at Damang due to the completion of the Damang pit cutback as well as lower production at Asanko. All-in costs increased by 10% to US$1,220/oz in 2022 from US$1,112/oz in 2021. The region produced adjusted free cash flow (excluding Asanko) of US$219m in 2022 compared to US$292m in 2021. As previously noted, we continue to work on the future of both Damang and our share in Asanko and will provide an update to the market in due course. The political and economic environment in Ghana has become more challenging with developments in the latter part of 2022 and the early part of 2023 particularly concerning. We continue to engage with government individually and through industry bodies to reiterate our stance on key fiscal matters. The process of claiming certain rebates relating to our Development Agreements has become more onerous. Chile Significant progress has been made by the team at Salares Norte since construction began in 2020. However COVID-19 and severe weather conditions continued to impact activities on site during 2022, with Gold Fields announcing a slight delay to the project in our H1 2022 results in August (from Q1 2023 to Q2 2023). In addition to these challenges, ongoing skills shortages faced by the main contractor at Salares Norte have resulted in further delay, with first gold now expected to be achieved in Q4 2023. US$329m was spent on Salares Norte during 2022, comprising US$296m in capex, US$32m in exploration, a US$5m loss on the realised portion of the FX hedge and US$2m of other costs, partially offset by a US$6m release in working capital. As at the end of December 2022, total capex spent on the project was US$758m. 2023 will be another capital intensive year for the project, with US$227m in project capital budgeted. At the end of December 2022, the total project progress stood at 87% (end-December 2021: 62%), construction progress was 86% (end-December 2021: 55%) and the processing plant construction stood at 77% (end-December 2021: 36%). The heavy mine equipment shop and the freshwater system were completed during 2022 with the grinding, crusher and stockpile areas having made significant progress. Pre-stripping of the Brecha Principal pit was completed in October 2022 with 50.6Mt of waste moved to date. Stockpiling of ore commenced in Q4 2022 with 422kt (79koz of contained gold) built up by 31 December 2022. During 2022, US$32m was spent on exploration, resulting in a total of 18,836m being drilled. We will continue to invest in exploration within the area to add to the LOM production pipeline. The further delay in the project, with first gold now expected in Q4 2023, has reduced the planned production for the year to range from 15koz to 35koz (previously 100koz announced in August 2022). However the quick ramp-up remains intact, with production expected to increase to 500koz in 2024, before reaching full production of c.600koz in 2025, in line with the original build-up schedule. The cost guidance provided for the project remains largely in place, when adjusted for inflation. For the six-year period from 2024 to 2029, average annual production is expected to be 500koz at an average AISC of US$660/oz. For the 10-year period from 2024 to 2033, average annual production is expected to be 355koz at an average AISC of US$745/oz. The overall project capex is now forecast at US$1,020m, with the majority of the increase related to the delay in getting the project into production.

Peru Equivalent gold production at Cerro Corona increased by 5% to 261koz in 2022 from 248koz in 2021, driven by higher gold and copper recoveries. Total all-in cost per equivalent ounce decreased by 4% to US$998 per equivalent ounce from US$1,040 per equivalent ounce in 2021. Cerro Corona generated adjusted free cash flow of US$76m in 2022, a 33% increase from the US$57m generated in 2021 which was impacted by a collar hedge on the copper price during the year. Mineral reserve and resource update Group attributable Gold Measured and Indicated Exclusive Mineral Resource (EMR) decreased 3.7% to 31.1Moz at 31 December 2022 from 32.2Moz at 31 December 2021 while attributable Inferred Exclusive Mineral Resource (EMR) decreased 6.6% to 11.2Moz (31 December 2021: 11.9Moz). Group attributable Proved and Probable Gold Mineral Reserves decreased 2.6% to 46.1Moz at 31 December 2022 (31 December 2021: 47.4Moz). The decrease in both Resources and Reserves net of depletion is primarily due to depletion and cost inflation. Significant reduction in the Mineral Resources not reflected in these numbers relates to write down of FSE. Gold Fields provided a metal price deck and exchange rate guidance to the operations for Resource and Reserve modelling in May 2022. A late change was made to this guidance in November 2022 in response to ongoing inflationary pressures. This change entailed a US$100/oz increase in the Gold Reserve and Resource prices to US$1,400/oz and US$1,600/ oz, respectively. This change has been applied to the financials across all of the operations but has not been applied to all aspects of the Reserve process. Given the late timing of this change, the Australian and Ghanaian operations have not yet updated their physicals and optimisations with the increased price deck. However, the South American operations and South Deep have been able to apply the updated price deck throughout.

The Mineral Resources and Mineral Reserve supplement, prepared in terms of South African Code for the Reporting of Exploration Results, Mineral Resources and Mineral Reserves, 2016 edition (SAMREC Code), will be published with the Integrated Annual Report at the end of March 2023. Update on leadership changes Gold Fields is pleased to announce the appointment of Kelly Carter (current VP: Legal and Corporate Affairs for the Australia region) as EVP: Group Head of Legal and Compliance. The recruitment process for the other executives that will be leaving Gold Fields is well advanced and we aim to make appointments within the coming months. The search process for a permanent CEO has also commenced. Outlook and 2023 guidance 2023 is going to be another significant capex year for Gold Fields, given the remaining project capital at Salares Norte as well as the elevated level of sustaining capex across the portfolio, in order to maintain the production base of the Group. At this point in time, Gold Fields is not in a position to provide 2023 production guidance for Asanko. Consequently, Group guidance excludes our share of the Asanko Joint Venture. For 2023, attributable gold equivalent production (excluding Asanko) is expected to be between 2.25Moz – 2.30Moz (2022 comparable was 2.32Moz). AISC is expected to be between US$1,300/oz – US$1,340/oz, with AIC expected to be US$1,480/oz – US$1,520/oz. Studies on a microgrid at St Ives are ongoing. Should these studies be finalised and the project approved during the year, we estimate US$25/oz will be added to both the AISC and AIC guidance ranges. In this case, the ranges for AISC will be US$1,325/oz – US$1,365/oz and AIC will be US$1,505/oz – US$1,545/oz, respectively. The exchange rates used for our 2023 guidance are: R/US$17.00 and US$/A$0.70. Total capex for the Group for the year is expected to be between US$1.110bn – US$1.170bn. Sustaining capital is expected to be between US$820m – US$850m. The increase in sustaining capital is driven largely by US$159m in capital stripping at Salares Norte and capital related to pre-stripping of stages 4 and 5 of the Gruyere pit together with an upgrade of the pebble crusher at Gruyere. Non-sustaining capex expected to be between US$290m and US$320m, with the largest component of this being the Salares Norte project capital of US$230m. Longer term guidance Taking into account the expected changes in production from the different assets (growth from Salares Norte and South Deep; declines at Damang and Cerro Corona) in the portfolio described above, we expect production for the next three years (excluding Asanko) to be: 2023: 2,250koz – 2,300koz 2024: 2,720koz – 2,770koz 2025: 2,790koz – 2,820koz Martin Preece Interim Chief Executive Officer 23 February 2023 4 2022Gold Fields Reviewed Results

Year ended 31 December 2022 compared with year ended 31 December 2021 Results for the Group Safety and Health Tragically, a fatal incident occurred at our St Ives Gold Mine in Australia on 11 October 2022, when a raise bore operator was dismantling a raise bore head. The incident is still under investigation. On 5 February 2023, there were two fatal injuries at the Asanko mine in Ghana, which is managed by Galiano Gold. The two contractors were involved in a vehicle incident at the mine. Since Asanko is not managed by Gold Fields these fatalities will not be reflected in Gold Fields safety statistics. Our deepest sympathies go out to the family, friends and colleagues of all three deceased. Five serious injuries were also recorded for the year ended 31  December  2022, though this was lower than the nine injuries reported in 2021. The injury severity rate was unchanged. The annual Total Recordable Injury Frequency Rate (TRIFR) for the Group was 2.04, continuing the reduction achieved in recent years and reversing the regression reported in H1 2022. Governments relaxed most or all remaining restrictions in H2 2022. 1,367 COVID-19 cases were recorded in H2 2022, compared to 2,058 cases in H1 2022 and 1,395 cases in H2 2021. Almost all the Gold Fields cases were mild or asymptomatic, with only five people being hospitalised briefly in H2 2022. Since the beginning of the pandemic, Gold Fields has undertaken more than 330,000 tests among its 22,000 strong workforce. To date we have had 8,700 COVID-19 positive cases among employees and contractors. Regrettably, 20 employees and contractors have passed away from COVID-19. Our concept of Zero Harm does not only cover physical injuries and health, but also includes the psychological well-being of our People. As such we strive to create workplaces that welcome diversity, are free from discrimination, and, above all, are safe for women and free from sexual harassment and bullying. An external review into gender safety at our offices and operations is currently being undertaken by Elizabeth Broderick, a world- renowned thought leader and independent expert with the United Nations.

The employee or contractor is unable to perform any functions. 3 A Restricted Work Injury (RWI) is a work-related injury sustained by an employee or contractor which results in the employee or contractor being unable to perform one or more of their routine functions for a full working day, from the day after the injury occurred. The employee or contractor can still perform some of his duties. 4 A Medically Treated Injury (MTI) is a work-related injury sustained by an employee or contractor which does not incapacitate that employee and who, after having received medical treatment, is deemed fit to immediately resume his/her normal duties on the next calendar day, immediately following the treatment/re-treatment. 5 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 2022, continuing the trend of preceding years. Freshwater withdrawal was 8.5 gigalitres (GL) in 2022 compared with 9.4 GL in 2021, mainly due to a decrease in water withdrawal at Tarkwa as the operation improved its water recycling. Tarkwa installed a micro-filtration unit on a clarifier return line to the carbon-in-leach plant. Water recycled/reused was 75% of total water use in 2022, the same as in 2021. The Group is on track to meet its 2030 target of 1%. Group energy spend was US$424m (21% of operating costs) for 2022 compared with US$341m (18% of operating costs) in 2021, reflecting increased production and higher fuel prices in 2022. Group energy use increased 1% to 14.1 petajoules (PJ). Energy savings of 1.1 PJ were achieved (8% of 2022 energy use), compared with 1.2 PJ (9% of energy consumption) in 2021. Scope 1 and 2 CO₂ emissions were 1.7 Mt in 2022, unchanged from 2021. CO₂ emissions intensity increased slightly to 8.7 kg CO₂e/t mined from 8.6 kg CO₂e/t in 2021. Electricity from renewables accounted for 13% in 2022, with renewables providing 54% of electricity consumed by our Agnew mine in Australia and the electricity supply to our Cerro Corona mine in Peru was certified 100% renewable. Construction of the R715m, 50 MW solar plant at South Deep in South Africa was completed within budget and commissioning is under way. Despite some delays due to COVID-19, the Gruyere solar farm (12MW solar, 4.4MW battery) was successfully commissioned within budget of USD20m in 2022. Wind trials and an Environmental Impact Assessment are under way at South Deep. The Salares Norte Chinchilla Relocation Plan remains suspended, pending review by the Authority of the revised Compliance Programme. The relocation delay is not expected to delay construction of the project. The release of the Global Industry Standard on Tailings Management (GISTM) in 2020 represented a significant turning point in the regulation of tailings management and transparency. As part of its 2030 ESG targets, Gold Fields is working towards conforming with the GISTM of its high- priority facilities by August 2023 and all other facilities by August 2025, including reducing the number of active upstream raised facilities from five to three. In January 2023, the United Nations Environment Programme, the Principles for Responsible Investment and the ICMM announced the launch of the Global Tailings Management Institute, which will oversee the mining sector’s conformance with the GISTM.

Revenue Attributable equivalent gold production, (including Asanko) increased by 3% from 2.340Moz in 2021 to 2.399Moz in 2022. Attributable equivalent gold production at Asanko decreased by 19% from 94,600oz in 2021 to 76,700oz in 2022. Revenue from Asanko is not included in Group revenue as Asanko results are equity accounted. At the South Africa region, managed production increased by 12% from 9,102kg (292,600oz) in 2021 to 10,200kg (327,900oz) in 2022. Attributable production at South Deep increased by 12% from 8,776kg (282,200oz) in 2021 to 9,836kg (316,200oz) in 2022. The increase was due to the continuous productivity improvement programmes introduced in 2019 which are sustainably delivering results. Gold sold increased by 12% from 9,102kg (292,600oz) to 10,200kg (327,900oz). Managed gold production at the West African operations (including Asanko), decreased by 4% from 870,700oz in 2021 to 838,300oz in 2022 mainly due to decreased production at Damang with the completion of mining at the Damang Pit Cutback (DPCB) and decreased production at Asanko due to the temporary cessation of mining activities in July 2022 and lower grade material processed from stockpiles. Attributable gold production at the West African operations (including Asanko), decreased by 4% from 793,100oz in 2021 to 762,100oz in 2022.

The average US Dollar/Rand exchange rate weakened by 11% from R14.79 in 2021 to R16.37 in 2022. The average Australian/US Dollar exchange rate weakened by 8% from A$1.00 = US$0.75 to A$1.00 = US$0.69. Gold equivalent ounces sold (excluding Asanko) increased by 3% from 2.34Moz in 2021 to 2.40Moz in 2022. Revenue increased by 2% from US$4,195m in 2021 to US$4,287m in 2022 due to the higher gold sold, partially offset by the lower gold price received. Cost of sales before amortisation and depreciation Cost of sales before amortisation and depreciation increased by 6% from US$1,662m in 2021 to US$1,763m in 2022 mainly due to inflationary increases affecting all the regions, partially offset by the weakening of the South African Rand and Australian Dollar. Effective mining inflation for 2022 was as follows: Group Effective mining inflation Australia 12.3% South Africa 9.6% Ghana (US based) 12.6% Chile (US based) 7.3% Peru (US based) 14.3% Group weighted 10.7% At the South Africa region, at South Deep, cost of sales before amortisation and depreciation increased by 14% from R4,510m (US$305m) in 2021 to R5,138m (US$314m) in 2022 mainly due to 5% higher volumes mined as well as inflationary increases. At the West Africa region, (excluding Asanko), cost of sales before amortisation and depreciation increased by 14% from US$460m in 2021 to US$524m in 2022 mainly due to the impact of inflationary cost pressures. In addition, at Tarkwa there was a 12% (3Mt) increase in operational waste tonnes mined and a 19% (2Mt) increase in ore tonnes mined. Tarkwa had a gold-in-process credit to cost of US$36m in 2022 compared with a US$30m credit to cost in 2021. At Damang operational waste tonnes mined decreased by 47% (7Mt) and ore tonnes minded decreased by 29% (2Mt) as mining at the Damang Pit Cutback was completed during 2022. Damang had a gold-in-process credit to cost of US$41m in 2022 compared with a US$72m credit to cost in 2021. The decrease in the gold-in-process credit to cost more than offset the decrease in operating cost as a result of lower tonnes mined. At the South America region, at Cerro Corona, cost of sales before amortisation and depreciation decreased by 1% from US$176m in 2021 to US$175m in 2022. The cost of sales before gold inventory change and amortisation and depreciation increased by 18% to US$225m in 2022 from US$190m in 2021. This increase was more than offset by the 257% increase in the gold-inventory credit to cost to US$50m in 2022 from US$14m in 2021. At the Australia region, cost of sales before amortisation and depreciation increased by 14% from A$960m (US$721m) in 2021 to A$1,091m (US$756m) in 2022 mainly due to inflationary pressures on commodity inputs, employee and contractor costs and structural increases in costs relating to higher support and paste fill costs at Granny Smith mine due to increased mining depth at the underground mine. In addition, higher operational waste tonnes were mined at Gruyere and St Ives. Amortisation and depreciation Amortisation and depreciation for the Group increased by 18% from US$713m in 2021 to US$844m in 2022 mainly due to the higher ounces mined at Tarkwa, Cerro Corona and St Ives in 2022. Investment income Investment income increased by 63% from US$8m in 2021 to US$13m in 2022 due to higher interest received as a result of higher interest rates and higher cash and cash equivalents. Finance expense Finance expense for the Group decreased by 20% from US$91m in 2021 to US$73m in 2022 due to lower borrowings and higher interest capitalised in 2022. Interest expense on borrowings of US$75m lease interest of US$23m, rehabilitation interest of US$12m and silicosis liability unwinding of US$1m, partially offset by interest capitalised of US$38m in 2022 compared with interest expense on borrowings of US$80m and lease interest of US$24m, partially offset by interest capitalised of US$13m in 2021. The increase in interest capitalised relates to higher cumulative spend on Salares Norte. 9 2022Gold Fields Reviewed Results

Non-recurring items Non-recurring expenses increased by 175% from US$89m in 2021 to US$245m in 2022. Non-recurring expenses of US$245m in 2022 mainly includes: • Impairment of US$325m of the Tarkwa cash-generating unit (CGU). The after tax impairment is US$220m. The impairment calculation is based on the fair value less cost of disposal (FVLCOD) calculated using a combination of the market (resource value) and income approach using level 3 of the fair value hierarchy (2022 life of mine plan) with the following assumptions: – Gold price – US$ per ounce – 2023 – US$1,740 – 2024 – US$1,730 – 2025 – US$1,700 – 2026 – US$1,650 – Long-term – US$1,620 – Resource price of US$71 per ounce – Resource ounces of 3.3 million ounces – Life of mine of 13 years – Discount rate of 15.9% • The impairment is mainly due to an increase in the discount rate from 8.3% to 15.9% as a result of increases in the Ghana country risk premium and the risk free rate as well as inflationary cost pressures experienced in 2022. The carrying value after impairment for the Tarkwa CGU is US$812m. The information underlying the impairment calculation may be subject to further adjustments in the future. • Impairment of US$63m of the Cerro Corona CGU. The after tax impairment is US$44m.

The carrying value after impairment for the Cerro Corona CGU is US$477m. The information underlying the impairment calculation may be subject to further adjustments in the future. • US$114m related to impairment of FSE. Management has actively been engaged in the process of disposing of FSE in 2022. The disposal process proved unsuccessful and no offers were received. Management’s assessment is that it is unlikely the investment could be sold for any value and wrote off the investment by US$114m to a carrying value of nil; • US$18m related to an expected credit loss against a contractor loan at Tarkwa and Damang; • US$11m related to restructuring costs in Ghana; and • US$3m related to impairment of redundant assets at various operations. These were partially offset by: • US$267m income related to the Yamana break fee, net of costs. As a result of Yamana entering into an arrangement agreement with Pan American Silver Corp and Agnico Eagle Mines Limited, Gold Fields terminated the agreement in respect of the proposed acquisition of Yamana. In accordance, within the terms of the arrangement agreement, Yamana was required to pay Gold Fields a termination fee of US$300m. The fee has been partially offset by transaction costs of US$33m; • US$10m income related to profit on disposal of assets; • US$2m income arising on adjustment of silicosis provision; and • US$10m income arising on rehabilitation provision year-end adjustments. Non-recurring expenses of US$89m in 2021 mainly includes: • Impairment of FSE of US$31m based on the fair value less cost of disposal of the investment which was indirectly derived from the market value of Lepanto Consolidated Mining Company; • Expected credit loss against a contractor loan of US$41m at Tarkwa and Damang; • US$10m impairment of capitalised exploration costs at St Ives based on technical and economic parameters of various studies; • US$2m write-off of redundant assets in Peru; • Restructuring costs at Tarkwa of US$2m; • Donations made to various bodies in response to COVID-19 of US$1m; and • A cost arising on the rehabilitation year-end adjustments of US$11m; partially offset by; • Profit on disposal of assets of US$9m. 10 2022Gold Fields Reviewed Results

Royalties Government royalties for the Group decreased by 2% from US$112m in 2021 to US$110m in 2022 due to the effect of the weakening of the South  African Rand and Australian Dollar on converting South Deep’s royalties and the Australian region’s royalties from local currencies to US Dollars. In local currencies the royalties in Australia and South Africa increased in line with the higher revenue. Mining and income taxation The taxation charge for the Group increased by 4% from US$425m in 2021 to US$442m in 2022 in line with the higher profit before tax. Normal taxation increased by 6% from US$449m in 2021 to US$475m in 2022 mainly due to US$65m tax paid to the South African Revenue Service on the Yamana break fee as well as US$19m additional tax charge to the Ghana Revenue Authority related to transfer pricing. The deferred tax credit increased by 38% from US$24m in 2021 to US$33m in 2022. The increase is due mainly to deferred tax assets of US$97m that were raised in 2021 for Salares Norte that resulted in a significant deferred tax credit in the prior year. Profit for the period Profit for the period decreased by 13% from US$830m in 2021 to US$722m in 2022. Net profit attributable to owners of the parent for the Group decreased by 10% from US$789m or US$0.89 per share in 2021 to US$711m or US$0.80 per share in 2022. Headline earnings attributable to owners of the parent for the Group increased by 19% from US$890m or US$1.00 per share in 2021 to US$1,061m or US$1.19 per share in 2022. Normalised profit for the Group increased by 7% from US$929m or US$1.05 per share in 2021 to US$860m or US$0.97 per share in 2022. Normalised profit Normalised profit reconciliation for the Group is calculated as follows: US$’m December 2022 December 2021 Profit for the period attributable to owners of the parent 711.0 789.3 Non-recurring items 245.1 89.0 Tax effect of non-recurring items (57.5) (4.8) Non-controlling interest effect of non- recurring items (24.1) (4.2) Share of results of equity-accounted investees – Asanko impairment — 52.8 (Gain)/loss on foreign exchange (6.7) 1.9 Tax effect on foreign exchange 2.8 1.2 Non-controlling interest effect on foreign exchange 0.5 0.5 (Gain)/loss on financial instruments (24.0) 100.4 Tax effect on financial instruments 7.5 (11.6) Non-controlling interest effect on financial instruments 0.9 0.9 South Deep deferred tax change1 4.6 — Salares Norte deferred tax asset raised — (86.7) Normalised profit attributable to owners of the parent 860.1 928.7 Normalised profit is considered an important measure by Gold Fields of the profit realised by the Group in the ordinary course of operations. In addition, it forms the basis of the dividend pay-out policy. Normalised profit is defined as profit excluding gains and losses on foreign exchange, financial instruments and non-recurring items after taxation and non-controlling interest effect. 1 During June 2022, the South African Revenue Services published the draft 2022 Rates & Monetary Bill, inclusive of an amendment to the gold tax formula from Y = 34 – 170/X to Y = 33 – 165/X in respect of year assessments ending on or after 31 March 2023, which is considered to be substantively enacted. This resulted in 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, decreasing from 29% at 31 December 2021 to 28% at 31 December 2022, amounting to a charge of R76.2m (US$4.6m) through profit or loss. Cash flow Cash flow from operating activities Cash inflow from operating activities increased by 7% from US$1,599m in 2021 to US$1,714m in 2022. The increase was mainly due to a higher profit before royalties and taxation largely due to the Yamana break fee received. This was partially offset by a higher royalties and taxation payment and a higher investment in working capital as a result of higher gold in process inventory due to stock piling in certain operations in 2022. The higher taxation payment included withholding tax of US$75m tax on the Yamana break fee which will be refunded in 2023, US$65m tax paid to the South African Revenue Service on the Yamana break fee as well as US$23m additional tax payment to the Ghana Revenue Authority related to transfer pricing. Dividends paid Dividends paid decreased by 9% from US$369m in 2021 to US$335m in 2022. The dividend paid of US$335m in 2022 comprised dividends paid to owners of the parent of US$305m related to the 2021 final and 2022 interim dividends and dividend paid to non-controlling interest holders of US$30m. The dividend paid of US$369m in 2021 comprised dividends paid to owners of the parent of US$322m related to the 2020 final and 2021 interim dividends and dividends paid to non-controlling interest holders of US$47m. Cash flow from investing activities Cash outflow from investing activities increased marginally from US$1,071m in 2021 to US$1,072m in 2022. Capital expenditure Capital expenditure decreased by 2% from US$1,089m in 2021 to US$1,069m in 2022. The capital expenditure of US$1,069m in 2022 comprised of sustaining capital expenditure of US$657m and non-sustaining capital expenditure of US$412m. The capital expenditure of US$1,089m for 2021 comprised of sustaining capital expenditure of US$576m and non-sustaining capital expenditure of US$513m. Sustaining capital expenditure, (excluding Asanko), increased by 14% from US$576m in 2021 to US$657m in 2022 mainly due to increases from South Deep, Damang, Tarkwa and Cerro Corona. Non-sustaining capital expenditure (excluding Asanko), decreased by 20% from US$513m in 2021 to US$412m in 2022. This movement is mainly attributable to lower project capital incurred while constructing Salares Norte. Growth expenditure of US$412m for 2022 comprised US$286m at Salares Norte, US$81m at the Australian operations, US$15m at Cerro Corona, US$20m at South Deep and US$10m at Damang. Growth expenditure of US$513m for 2021 comprised US$375m at Salares Norte, US$83m at the Australian operations, US$28m at Cerro Corona, US$21m at South Deep and US$6m at Damang. At the South Africa region at South Deep, capital expenditure increased by 47% from R1,320m (US$89m) in 2021 to R1,943m (US$119m) in 2022 mainly due to increased spending on the solar plant of R420m (US$26m) and the Doornpoort tailings storage facility (TSF) life of mine extension. At the West Africa region, (excluding Asanko), capital expenditure increased by 24% from US$232m in 2021 to US$289m in 2022. At Tarkwa, capital expenditure increased by 10% from US$209m to US$229m mainly due to additional expenditure on TSF Construction and higher capital waste expenditure driven by higher mining unit rates as a result of higher fuel price, explosives and contractor rise and fall costs. The higher capital waste expenditure was partially offset by a reduction of 18% in capital waste tonnes mined. Capital expenditure at Damang increased by 156% from US$23m to US$60m due to higher capital waste tonnes mined from Huni pit combined with the inflationary increases on the mining rate. Capital expenditure at Asanko (on a 100% basis) decreased by 62% from US$46m in 2021 to US$17m in 2022. The Asanko capital expenditure is not included in the Group capital expenditure as Asanko is equity accounted. At the South America region at Cerro Corona, capital expenditure decreased by 17% from US$56m in 2021 to US$46m in 2022, mainly due to lower construction activities at the Ana and Apron waste storage facilities. At Salares Norte, capital expenditure decreased by 21% from US$375m in 2021 to US$296m in 2022, mainly due to timing of project capital expenditure. 11 2022Gold Fields Reviewed Results

At the Australia region, capital expenditure increased by 2% from A$447m (US$336m) in 2021 to A$457m (US$317m) in 2022. At St Ives, capital expenditure increased by 6% from A$138m (US$103m) to A$145m (US$101m) due to increased pre-strip activities at Neptune stage 7 pit. Agnew, capital expenditure increased by 5% from A$117m (US$88m) to A$123m (US$85m) mainly due to increased expenditure incurred on the mill crushing circuit replacement project and a 100-room expansion of the accommodation village. At Granny Smith, capital expenditure increased by 6% from A$134m (US$100m) in 2021 to A$141m (US$98m) in 2022 mainly due to increased expenditure on development of the Z135 area and increased expenditure on a new TSF. At Gruyere, capital expenditure (50% basis) decreased by 18% from A$58m (US$44m) in 2021 to A$48m (US$33m) in 2022 reflecting the completion of pre-stripping stages 2 and 3 of the pit.

All-in sustaining and total all-in cost The Group all-in sustaining costs increased by 4% from US$1,063/oz in 2021 to US$1,105/oz in 2022 mainly due to higher sustaining capital expenditure and higher cost of sales before amortisation and depreciation, partially offset by higher gold sold and the 11% weakening of the South African Rand against the US Dollar and 8% weakening of the Australian Dollar against the US Dollar . If the all-in sustaining costs are normalised by using the same exchange rates as in 2021, the all-in sustaining costs would be US$1,164/oz for 2022. This represents a 10% increase in all-in sustaining costs compared with 2021. Total all-in cost increased by 2% from US$1,297/oz in 2021 to US$1,320/oz in 2022 mainly due to higher sustaining capital expenditure and higher cost of sales before amortisation and depreciation, partially offset by higher gold sold, lower non-sustaining capital expenditure and the 11% weakening of the South African Rand against the US Dollar and 8% weakening of the Australian Dollar against the US Dollar. The lower non-sustaining capital expenditure was mainly at Salares Norte which decreased from US$375m in 2021 to US$286m in 2022 due to timing of expenditure on the project. Normalising for the exchange rate differences, the total all-in cost would be US$1,384/oz for 2022, a 7% increase when compared with 2021. Excluding the project construction capital at Salares Norte, total all-in cost increased by 4% to US$1,197/oz in 2022 from US$1,148/oz in 2021. The Group all-in sustaining and all-in cost were below the guidance provided in February 2022. The actual all-in sustaining costs of US$ 1,105oz, if adjusted to 2022 guidance exchange rates (R/US$15.55 and US$/A$0.76) is US$1,160/oz which is well within the guidance range of US$1,140/oz – US$1,180/oz. The actual all-in cost of US$1,320/oz, if adjusted to 2022 guidance exchange rates is US$1,381/oz which is within the guidance range of US$1,370/oz – US$1,410/oz. 13 2022Gold Fields Reviewed Results

Productivity improvement programmes that were introduced in 2019 are sustainably delivering results and further enhancements will ensure sustained delivery. Gold production increased by 12% to 10,200kg (327,900oz) in 2022 from 9,102kg (292,600oz) in 2021. The increased gold production was due to improved efficiencies resulting in increased volumes mined and processed as well as improved mine call factor and plant recovery factor. Underground reef ore processed increased by 2% to 1,571kt in 2022 from 1,536kt in 2021. North of Wrench increased its contribution YoY from 71% to 81%, while Current Mine reduced its contribution from 29% to 19% as part of the focus to transition away from Current Mine to higher productivity North of Wrench. Underground reef grade mined decreased by 1% to 6.24g/t in 2022 from 6.33g/t in 2021 as a result of the mining footprint and mining mix. Underground reef yield increased by 9% to 6.38g/t in 2022 from 5.84g/t in 2021 due to an increase in mine call factor and plant recovery factor. Waste mined decreased by 3% to 195kt in 2022 from 201kt in 2021 as  some cuts intersected reef and began mining reef in line with the Mine Plan. Total development increased by 13% to 11,594m in 2022 from 10,282m in 2021 as a result of improved operational efficiencies and an additional drill rig in line with the ramp-up plan. Secondary support decreased by 16% due to less backlog and rehabilitation support requirements while backfill increased by 12% in 2022 as more stopes were available for backfilling. Surface re-mining decreased marginally to 1,227kt in 2022 from 1,232kt treated in 2021. Total yield increased by 10% to 3.42g/t in 2022 from 3.11g/t in 2021 largely driven by the increase in mine call factor and plant recovery factor. Total all-in cost increased by 9% to R713,624/kg (US$1,356/oz) in 2022 from R655,826/kg (US$1,379/oz) in 2021 with the prevailing inflationary pressures and higher capital costs partially offset by higher gold sales. All- in cost in US Dollar terms decreased by 2% as a result of the weakening of the South African Rand by 11% from R14.79 in 2021 to R16.37 in 2022. Cost of sales before amortisation and depreciation increased by 13% to R5.1bn (US$314m) in 2022 from R4.5bn (US$305m) in 2021. Cost of sales before gold inventory change and amortisation and depreciation increased by 15% to R5.3bn (US$325m) in 2022 from R4.6bn (US$312m) in 2021 mainly due to a 5% increase in total tonnes mined, a 2% increase in total tonnes milled and inflationary increases on consumables, contractors, electricity and employee costs. Gold inventory credit to cost increased to R175m (US$11m) in 2022 from R108m (US$7m) in 2021 due to a build up of stockpile and gold in circuit. Capital expenditure increased by 47% to R1.9bn (US$119m) in 2022 from R1.3bn (US$89m) in 2021 as detailed below. Sustaining capital expenditure increased by 58% to R1.6bn (US$98m) in 2022 from R1.0bn (US$69m) in 2021 mainly due to the higher spend on construction of the solar plant of R420m (R547m in 2022 vs. R127m in 2021) and the Doornpoort Tailings Storage Facility extension R34m (R123m in 2022 vs. R89m in 2021). Non-sustaining capital expenditure increased by 11% to R334m (US$20m) in 2022 from R301m (US$20m) in 2021. This increase was mainly due to increased development. Adjusted free cash flow increased by 47% to R2.1bn (US$129m) in 2022 compared to R1.4bn (US$97m) in 2021. The increase is mainly due to higher gold sold at a higher price, partially offset by higher cost of sales before amortisation and depreciation, as well as higher capital expenditure. Guidance Guidance for 2023 is as follows: • Gold produced ~ 10,800kg (347,200oz); • Capital expenditure ~ R1,855m (US$109m); • All-in sustaining costs ~ R730,000/kg (US$1,330/oz); and • Total all-in cost ~ R730,000/kg (US$1,330/oz). The increase in AIC is due to higher cost of sales before amortisation and depreciation as a result of inflationary increases, partially offset by higher gold sold and lower total capital expenditure. 14 2022Gold Fields Reviewed Results

Yield increased by 1% to 1.18g/t in 2022 from 1.17g/t in 2021 due to higher grades processed. Ore rehandled from stockpiles was 1,250kt at a head grade of 1.42/t in 2022 compared to 3,336kt at a head grade of 0.78g/t in 2021. Total tonnes mined, including capital waste stripping, decreased by 4% to 87.6Mt in 2022 from 91.7Mt in 2021 due to less capital waste stripped in 2022. Ore mined increased by 19% to 14.0Mt in 2022 from 11.8Mt in 2021 due to exposed ore areas in Akontansi Central and Teberebie Cut 7 pits, as a result of more capital waste stripped in 2021. Capital waste stripped decreased by 18% to 43.4Mt in 2022 from 53.1Mt in 2021. Operational waste increased by 12% to 30.2Mt in 2022 from 26.8Mt in 2021, due to more tonnes mined below the capital waste elevations. All-in cost increased by 8% to US$1,248/oz in 2022 from US$1,155/oz in 2021 due to higher capital expenditure and higher cost of sales before amortisation and depreciation, partially offset by higher ounces sold. Cost of sales before amortisation and depreciation increased by 20% to US$371m in 2022 from US$310m in 2021. Cost of sales before gold inventory change and amortisation and depreciation increased by 20% to US$407m in 2022 from US$340m in 2021 mainly due to a 19% increase in ore tonnes mined, a 12% increase in operational waste tonnes mined and inflationary increases mainly impacting fuel, explosives, grinding media and employee costs. Gold inventory credit to cost increased to US$36m in 2022 from US$30m in 2021 due to a build-up of stockpiles. Total capital expenditure increased by 10% to US$229m in 2022 from US$209m in 2021 as a result of increased expenditure on capital waste stripping cost. The increase in capital waste stripping cost is due to higher mining cost driven by higher fuel price, explosives and contractor rise and fall cost. Tarkwa generated adjusted free cash flow of US$161m in 2022 compared to US$194m in 2021 mainly due to higher capital expenditure and higher cost of sales. Guidance The estimate for 2023 is as follows: • Gold produced ~ 545,000oz; • Sustaining capital expenditure ~ US$243m. • All-in sustaining costs ~ US$1,390/oz; and • Total all-in cost ~ US$1,390/oz. The increase in AIC is due to higher cost of sales before amortisation and depreciation and higher sustaining capital as a result of inflationary increases, partially offset by higher gold sold. 15 2022Gold Fields Reviewed Results

Yield decreased by 11% to 1.50g/t in 2022 from 1.68g/t in 2021. This is due to the completion of Damang Pit in November 2022 and mining through transition in the lower grades of Huni pit. Total tonnes mined decreased by 11% to 21.3Mt in 2022 from 24.0Mt in 2021 which was planned as Damang Pit Cut Back (DPCB) was scheduled to be completed in November 2022. Ore tonnes mined decreased by 29% to 5.9Mt in 2022 from 8.3Mt in 2021 due to the depletion of DPCB which was forecasted to be completed in November 2022. Capital waste tonnes mined were 7.6Mt in 2022 compared to 1.0Mt in 2021 due to continuation of waste stripping at Huni Pit. Operational waste tonnes decreased by 47% to 7.8Mt in 2022 from 14.8Mt in 2021 due to the reduced mining rate and completion of DPCB. Strip ratio increased by 37% to 2.6 in 2022 from 1.9 in 2021 due to increased stripping to expose the ore zones of the main orebody at Huni Pit. Gold mined decreased by 30% to 282koz in 2022 from 406koz in 2021 due to depletion of DPCB which was completed in November 2022 and mining to expose the orebody at Huni Pit. Given the plant capacity constraint, 3.5Mt of the 5.9Mt ore mined was processed in addition to 1.2Mt depleted from stockpile in 2022. The remaining 2.4Mt of the ore mined was added to the stockpile. The closing balance of the stockpile increased to 8.2Mt at an average grade of 0.90g/t in 2022 from 7.0Mt at an average grade of 0.95g/t in 2021. All-in cost increased by 27% to US$1,083/oz in 2022 from US$852/oz in 2021 due to lower gold sold, higher capital expenditure and higher cost of sales before amortisation and depreciation. Cost of sales before amortisation and depreciation increased by 1% to US$152m in 2022 from US$150m in 2021. Cost of sales before gold inventory change and amortisation and depreciation decreased by 13% to US$193m in 2022 from US$222m in 2021 mainly due to a 29% decrease in ore tonnes mined and a 47% decrease in operational waste tonnes mined despite processing volume remaining similar, partially offset by inflationary increases mainly impacting fuel, explosives, grinding media and employee costs. Gold inventory credit to cost decreased to US$41m in 2022 from US$72m in 2021 due to a lower build-up of stockpiles. Total capital expenditure increased by 157% to US$60m in 2022 from US$23m in 2021. Sustaining capital expenditure increased by 185% to US$50m in 2022 from US$17m in 2021 mainly due to the higher capital waste tonnes mined from Huni pit. Non-sustaining capital expenditure increased by 73% to US$10m in 2022 from US$6m in 2021 due to Far East Tailings Storage Facility (FETSF) raise. Damang generated adjusted free cash flow of US$58m in 2022 compared to US$98m in 2021 due to lower revenue resulting from lower gold sold, higher capital expenditure and higher cost of sales before amortisation and depreciation in 2022. Guidance The budget for 2023 is as follows: • Gold produced ~ 136,000oz; • Sustaining capital expenditure ~ US$7m; • Non-sustaining capital expenditure ~ nil; • All-in sustaining costs ~ US$1,830/oz; and • Total all-in cost ~ US$1,830/oz. The increase in AIC is mainly due to lower gold sold, and higher cost of sales before amortisation and depreciation as a result of increased processing of low grade stockpiles in 2023 and inflationary increases, partially offset by lower total capital expenditure.

Gold production decreased by 19% to 170,300oz (100% basis) in 2022 from 210,200oz (100% basis) in 2021, of which 76,700oz (2021: 94,600oz) was attributable to Gold Fields. The decrease was mainly due to lower yield which decreased by 17% to 0.91g/t in 2022 from 1.10g/t in 2021. The lower yield was a direct result of lower grade ore processed from stockpile in 2022 compared to higher grade fresh ore and stockpiles in 2021. Gold mined decreased by 63% to 94,500oz (100% basis) in 2022 from 257,100oz (100% basis) in 2021 due to the temporary cessation of mining activities in July 2022. Total tonnes mined decreased by 80% to 8.6Mt in 2022 from 43.7Mt in 2021 due to the temporary cessation of mining activities in July 2022. All-in cost decreased by 8% to US$1,435/oz in 2022 from US$1,559/oz in 2021 due to lower cost of sales before amortisation and depreciation and capital expenditure, partially offset by lower gold ounces sold. Cost of sales before amortisation and depreciation (on a 45% basis) decreased by 25% to US$82m in 2022 from US$110m in 2021. Cost of sales before gold inventory change and amortisation and depreciation (on a 45% basis) decreased by 37% to US$73m in 2022 from US$115m in 2021 mainly due to a 70% decrease in ore tonnes mined and a 81% decrease in operational waste tonnes mined due to the temporary cessation of mining activities in June 2022. Processing volume remained similar year-on-year. Gold inventory charge to cost (on a 45% basis) of US$9m in 2022 compared to a gold inventory credit to cost of US$5m in 2021 as the operation treated stockpiles in H2 2022.

As a result, equivalent gold production increased by 5% to 260,500oz in 2022 from 248,300oz in 2021. Total tonnes mined increased by 4% to 29.4Mt in 2022 from 28.3Mt in 2021 mainly due to an increase in ore mined of 54% to 13.8Mt in 2022 from 9.0Mt in 2021, partially offset by a decrease in the waste mined of 20% to 15.6Mt in 2022 from 19.3Mt in 2021 in line with the 2030 life of mine plan. In H1 2021, the operation experienced slope instability at the pit caused by abnormally high rainfall which triggered re-sequencing of the mining plan, impacting mining of ore at the eastern part of the mine. This resulted in mining more waste and less ore in 2021. In 2022, the focus was on catching up ore mining in line with the life of mine plan. This resulted in the increase of ore mined and decrease of waste mined as detailed above. 17 2022Gold Fields Reviewed Results

All-in cost per gold ounce increased by 93% to US$444/oz in 2022 from US$230/oz in 2021 mainly as a result of higher operating cost due to inflation and lower by-product credits due to a lower copper price, partially off-set by higher gold inventory credit due to higher low-grade stocking, higher gold ounces sold and lower capital expenditure. All-in cost per equivalent ounce decreased by 4% to US$998 per equivalent ounce in 2022 from US$1,040 per equivalent ounce in 2021 mainly due to higher equivalent ounces sold, higher gold inventory credit as a result of higher build-up of low grade stockpile in 2022 and lower capital expenditure, partially offset by higher operating cost due to inflation. Cost of sales before amortisation and depreciation decreased by 1% to US$175m in 2022 from US$176m in 2021. Cost of sales before gold inventory change and amortisation and depreciation increased by 18% to US$225m in 2022 from US$190m in 2021 mainly due to a 54% increase in ore tonnes mined partially offset by a 20% decrease in operational waste tonnes mined. Operational costs were also impacted by inflationary increases mainly impacting fuel, explosives, grinding media and employee costs. Gold inventory credit to cost increased to US$50m in 2022 from US$14m in 2021 due to a build-up of stockpiles in line with the life of mine strategy. Total capital expenditure decreased by 18% to US$46m in 2022 from US$56m in 2021. Sustaining capital expenditure increased by 13% to US$31m in 2022 from US$28m in 2021, mainly due to the replacement of the two crushers at the process plant (US$5m) in order to treat harder ore. Non-sustaining capital expenditure decreased by 47% to US$15m in 2022 from US$28m in 2021 mainly due to lower construction activities at Ana and Arpon waste storage facilities, and infrastructures relocation. During 2022, there were only activities at Ana waste storage facility and minor infrastructure relocations, all the activities are in line with the life of mine expansion plan. In line with higher equivalent ounces sold, adjusted free cash flow increased by 33% to US$76m in 2022 compared to US$57m in 2021. The 2022 adjusted free cash flow of US$76m includes a US$13m income tax refund from the Peruvian tax authority related to the deductibility of the 2021 copper hedge collar. Guidance  The estimate for 2023 is as follows: • Gold equivalents produced ~255,000oz; • Gold produced ~ 126,000oz; • Copper tonnes produced ~ 27,000t; • Sustaining capital expenditure ~ US$37m; • Non-sustaining capital expenditure ~ US$8m; • Copper price ~ US$8,400 per tonne; • Gold price ~ US$1,800/oz; • All-in sustaining costs ~ US$1,010/eq oz; • Total all-in cost ~ US$1,070/eq oz; • All-in sustaining costs ~ US$450/oz; and • Total all-in cost ~ US$570/oz. The increase in AIC per gold ounce and per equivalent ounce is due to higher cost of sales before amortisation and depreciation as a result of inflationary increases. Chile Salares Norte US$329m was spent on Salares Norte in 2022, made up of US$296m in capital expenditure, US$32m in exploration, a US$5m loss on the realised portion of the FX hedge and US$2m of other costs, partially offset by a US$6m release of working capital. At the end of December 2022, total project progress was 86.7% compared to 62.5% at 31 December 2021. Despite the challenges presented by COVID-19 and severe weather conditions during 2022, construction progress stood at 85.5%, at 31  December 2022 compared to 55% at 31 December 2021. However, skills sourcing challenges faced by the main contractor have resulted in a further delay with first gold expected in Q4 2023. Key items of the project were finalised during 2022, including the Heavy Mine Equipment Shop and the Fresh Water System, which were completed during the year. The processing plant construction was 77.3% completed at 31 December 2022, with the grinding, crusher and stockpile areas having made significant progress. Pre-stripping at the Brecha Principal Pit was completed in October 2022 with 50.6Mt waste moved for the project to date. Ore stockpiling commenced in Q4 2022 with 422kt (79koz of contained gold) added to the stockpile. During 2022, a total of 18,836m of exploration drilling was completed. We will continue to invest in exploration within the area in an attempt to add to the production pipeline. Guidance  The estimate for 2023 is as follows: • Gold equivalents produced ~15,000oz – 35,000oz; • Gold produced ~ 14,000oz – 32,000oz; • Silver produced ~ 1,000oz – 3,000oz; • Sustaining capital expenditure ~ US$159m; • Non-sustaining capital expenditure ~ US$227m; • Silver price ~ US$21/oz; and • Gold price ~ US$1,800/oz.

Corporate Press Announcements Gold Fields’ South Deep showcases transformation towards a world-class bulk mechanised mine On the back of material improvement in production and profitability over the past few years, Gold Fields’ South Deep Gold Mine showcased some of the key projects that will further improve the sustainability of the mine. The projects highlighted: Responsible management of Tailings Storage Facilities (TSF) The mine’s Tailings Storage Facilities (TSFs) comprise the active Doornpoort TSF and two older dormant TSFs. Expansion of the Doornpoort TSF was recently completed so that it now has sufficient capacity for the mine’s LoM. Innovation and technology at the heart of our operations – surface and underground South Deep showcased projects that demonstrate the adoption of innovation and technology as part of its everyday activities. This is headlined by the mine’s state-of-the-art surface control centre, which serves as the digital nerve centre of the mine’s activity across the value chain. South Deep has also embraced and deployed technology underground. South Deep recently acquired a Rhino 100 Master Driller – a multi- functional, mobile raise bore driller – which allows for faster, more accurate drilling, and a much bigger breaking point for blasting in the process of long hole stoping. Commissioning the Khanyisa solar plant With construction of the 50MW Khanyisa solar plant completed, South Deep is in the process of finalising the commissioning and optimising of the plant. The commissioning process involves balancing supply and demand of self-generated electricity to fully optimise the plant and ensure maximum benefit. The R715m solar plant will enhance the sustainability of South Deep and contribute to Gold Fields’ long-term commitment to Net Zero. South Deep currently consumes around 494GWH of electricity per year which represents 10% of the mine’s annual costs and 93% of its carbon emissions. The solar plant can generate 50MW or 103GWh/year. This will have major benefits for the social and economic sustainability of South Deep, and mitigate negative impacts on the environment by: • Significantly reducing the mine’s carbon footprint by around 110,000 tonnes of CO2/year. • Reducing reliance on the erratic national grid. • Dramatically lowering energy costs, saving around R123m, or 24%, of electricity costs/year. In time, the Khanyisa solar plant’s capacity will increase to 60MW, unlocking even further benefits. Gold Fields announces termination of arrangement agreement with Yamana As a result of Yamana Gold entering into an arrangement agreement with Pan American Silver and Agnico Eagle Mines. Gold Fields terminated the Arrangement Agreement in respect of the Yamana acquisition transaction. In accordance with the terms of the Arrangement Agreement, Yamana was required to pay Gold Fields a termination fee in the amount of US$300m within two business days from the date hereof. Gold Fields was disappointed by this outcome and continues to believe that the Transaction was a financially and strategically superior offer for shareholders of both Gold Fields and Yamana. Nonetheless, following Yamana’s change in recommendation, Gold Fields believed the most disciplined and prudent course of action to maximise Gold Fields’ shareholder value was to terminate the Arrangement Agreement. Gold Fields and its shareholders benefited from the termination fee. As a result of the 4% decrease in ore mined and 22% increase in grade, gold mined increased by 17% to 369,100oz in 2022 from 314,700oz in 2021. All-in cost decreased by 7% to A$1,431/oz (US$991/oz) in 2022 from A$1,541/oz (US$1,158/oz) in 2021 due to higher gold sold and lower capital expenditure, partially offset by higher cost of sales before amortisation and depreciation. Cost of sales before amortisation and depreciation (on a 50% basis) increased by 34% to A$145m (US$101m) in 2022 from A$108m (US$81m) in 2021. Cost of sales before gold inventory change and amortisation and depreciation (on a 50% basis) increased by 36% to A$167m (US$116m) in 2022 from A$123m (US$93m) in 2021 mainly due a 278% increase in operational waste tonnes mined, combined with inflationary pressures on commodity inputs and employee and contractor costs which resulted in higher production costs. Gold inventory credit to cost (on a 50% basis) of A$22m (US$15m) in 2022 compared to a gold inventory credit to cost of A$15m (US$11m) in 2021. Total capital expenditure (on a 50% basis) decreased by 18% to A$48m (US$33m) in 2022 from A$58m (US$44m) in 2021 reflecting completion of pre-stripping of stages 2 and 3 of the pit. Gruyere generated adjusted pre-tax free cash flow (on a 50% basis) of A$152m (US$106m) in 2022 compared with a cash flow of $79m (US$60m) in 2021. Guidance • The estimate for 2023 is as follows: • Gold produced ~ 170,000oz to 185,000 (50%); • Sustaining capital expenditure ~ A$98m (US$69m) (50%); • Non-sustaining capital expenditure ~ Nil (50%); • All-in sustaining costs ~ A$1,665/oz (US$1,170/oz); and • Total all-in cost ~ A$1,685/oz (US$1,180/oz). The increase in AIC is due to increased capital expenditure for the pre-stripping of stages 4 and 5 of the Gruyere pit and upgrade of the Mill pebble crusher and higher cost of sales before amortisation and depreciation as a result of inflationary increases. 22 2022Gold Fields Reviewed Results

Share certificates may not be dematerialised or rematerialised between Wednesday, 15 March 2023 and Friday, 17 March 2023, both dates inclusive. Outlook and 2023 guidance 2023 is going to be another big capex year for Gold Fields, given the remaining project capital at Salares Norte as well as the elevated level of sustaining capex across the portfolio, in order to maintain the production base of the Group. At this point in time, Gold Fields is not in a position to provide 2023 production guidance for Asanko. Consequently, Group guidance excludes our share of the Asanko Joint Venture. For 2023, attributable gold equivalent production (excluding Asanko) is expected to be between 2.25Moz and 2.30Moz (2022 comparable 2.32Moz). AISC is expected to be between US$1,300/oz and US$1,340/oz, with AIC expected to be US$1,480/oz to US$1,520/oz. Studies on a hybrid renewable microgrid power facility at St Ives are ongoing. Should these studies be completed and the project approved during the year, we estimate US$25/oz will be added to both the AISC and AIC guidance ranges. In this case, the ranges for AISC will be US$1,325/oz – US$1,365/oz and AIC will be US$1,505/oz – US$1,545/oz, respectively. This facility will include a wind farm, solar farm, battery energy storage system and diesel generation. The exchange rates used for our 2023 guidance are: R/US$17.00 and US$/A$0.70. The increase in AIC excluding Salares Norte is due to higher sustaining capital expenditure mainly at South Deep and Damang and higher cost of sales before amortisation and depreciation as a result of inflationary increases partially offset by higher production. The exchange rates used for our 2022 guidance are: R/US$15.55 and US$/A$0.76. Total capex for the Group for the year is expected to be between US$1.110bn and US$1.170bn. Sustaining capital is expected to be between US$820m and US$850m. The increase in sustaining capital is driven largely by US$159m in capital stripping at Salares Norte and capex related to pre-stripping of stages 4 and 5 of the Gruyere pit together with an upgrade of the Mill pebble crusher at Gruyere. Non-sustaining capex expected to be between US$290m and US$320m, with the largest component of this being the Salares Norte project capital of US$230m. Longer term guidance Taking into account the expected changes in production from the different assets (growth from Salares Norte and South Deep; declines at Damang and Cerro Corona) in the portfolio described about, we expect production for the next three years to be: 2023: 2,250koz – 2,300koz 2024: 2,720koz – 2,770koz 2025: 2,790koz – 2,820koz The above is subject to safety performance which limits the impact of safety-related stoppages and the forward-looking statement on page 59. 23 2022Gold Fields Reviewed Results

The key non-IFRS measures used and defined in the media release include: • Normalised earnings is defined as normalised profit attributable to owners of the parent which is defined as profit excluding gains and losses on foreign exchange, financial instruments and non-recurring items after taxation and non-controlling interest effect; • Normalised profit per share attributable to owners of the parent; • Net debt which is calculated as borrowings plus the current portion of borrowings and lease liabilities plus current portion of lease liabilities less cash and cash equivalents; • Net debt (excluding lease liabilities) which is calculated as borrowings plus the current portion of borrowings less cash and cash equivalents; • Adjusted free cash flow is calculated as cash flow from operating activities less net capital expenditure, environmental payments, lease payments and redemption of Asanko preference shares;1 • Adjusted free cash flow from operations is calculated as cash flow from operating activities less net capital expenditure, environmental payments and lease payments from the eight mining operations; • Adjusted EBITDA is required to be determined in terms of loan and revolving credit facilities agreements to evaluate compliance with debt covenants; • Sustaining capital expenditure represents the majority of capital expenditures at existing operations, including mine development costs, ongoing replacement of mine equipment and other capital facilities and other capital expenditures at existing operations; • Non-sustaining capital expenditure represents capital expenditures for major growth projects as well as enhancement capital for significant infrastructure improvements at existing operations; and • All-in sustaining costs and total all-in cost are presented to provide transparency into the costs associated with producing and selling an ounce of gold and is a common measure presented within the mining industry. 1 For 2022, adjusted free cash flow also excludes all cash flows related to the Yamana break fee. Auditor’s review The condensed consolidated financial statements of Gold Fields Limited for the year ended 31 December 2022 have been reviewed by the Company’s auditor, PricewaterhouseCoopers Inc. The auditor’s report does not necessarily report on all of the information contained in this media release. Shareholders are therefore advised that in order to obtain a full understanding of the nature of the auditor’s engagement they should refer to page 55 of the media release for a copy of the auditor’s report. The pro forma financial information has been reported on by the Group’s auditor, being PricewaterhouseCoopers Inc. Their unqualified reporting accountant’s report thereon is available on pages 56 to 57 of this report. Silicosis and Tuberculosis Class Action Settlement The Tshiamiso Trust has been established to carry out the terms of the settlement agreement reached between six gold mining companies (including Gold Fields) and claimant attorneys in the Silicosis and Tuberculosis class action. The Tshiamiso Trust is responsible for ensuring that all eligible current and former mineworkers across southern Africa with Silicosis or work-related Tuberculosis (or their dependants where the mineworker has passed away) are compensated pursuant to the Silicosis and Tuberculosis Class Action Settlement. As of 17 January 2023, 10 574 claimants have received benefits from the Trust in the aggregate amount of R936.1m. Further information on the progress in the implementation of the object of the Tshiamiso Trust and other details can be found at https://www.tshiamisotrust.com/ Provision raised Gold Fields has provided for the estimated cost of the above settlement based on actuarial assessments and the provisions of the silicosis and TB  class action settlement Agreement. At 31 December 2022, the provision for Gold Fields’ share of the settlement of the class action claims and related costs amounted to US$10.5m (R178.9m). The nominal value of this provision is US$14.4m (R244.7m). The ultimate outcome of this  matter however remains uncertain, with the number of eligible workers successfully submitting claims and receiving compensation being uncertain. The provision is consequently subject to adjustment in the future.

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.

Refer note 4. 5 The US$267.0 million income related to the Yamana break fee, net of costs. As a result of Yamana entering into an arrangement agreement with Pan American Silver Corp and Agnico Eagle Mines Limited, Gold Fields terminated the agreement in respect of the proposed acquisition of Yamana. In accordance, within the terms of the arrangement agreement , Yamana was required to pay Gold Fields a termination fee of US$300.0 million. The fee has been partially offset by transaction costs of US$33.0 million. 6 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 year ended 31 December 2022 was 0.5% of mining revenue (2021: 0.5%) equalling the minimum charge per the formula. 7 The Australian operations are subject to a 2.5% (2021: 2.5%) gold royalty on revenue as the mineral rights are owned by the state. 8 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% 9 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. 32 2022Gold Fields Reviewed Results

Mining and income taxation The components of mining and income tax are the following: South African taxation – dividend withholding tax (13.1) (24.3) – company and capital gains taxation (65.3) (3.8) – prior year adjustment – current taxation — 0.8 – deferred taxation (78.5) (27.4) – prior year adjustment – deferred taxation — (3.4) Foreign taxation – current taxation (390.8) (417.9) – prior year adjustment – current taxation1 (5.9) (3.5) – deferred taxation 111.5 54.6 Total mining and income taxation (442.1) (424.9) South Africa – current tax rates Mining tax2 Y=34-170/X Y=34-170/X Non-mining tax3 28.0% 28.0% Company tax rate 28.0% 28.0% International operations – current tax rates Australia 30.0% 30.0% Ghana 32.5% 32.5% Peru 29.5% 29.5% 1 The US$5.9m in 2022 comprises US$19.2m additional transfer pricing charges at Tarkwa and Damang, partially offset by a refund of US$13.3m relating to hedges at Peru. 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. During June 2022, the South African Revenue Services published the draft 2022 Rates & Monetary Bill, inclusive of an amendment to the gold tax formula from Y = 34 – 170/X to Y = 33 – 165/X in respect of year assessments ending on or after 31 March 2023, which is considered to be substantively enacted. This resulted in 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, decreasing from 29% at 31 December 2021 to 28% at 31 December 2022, amounting to a charge of R76.2m (US$4.6m) through profit or loss. 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 will be reduced from 28% to 27% for tax years ending on after 31 March 2023, and is considered to be substantively enacted. 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%, on the basis that these rates are considered to be substantively enacted. 33 2022Gold Fields Reviewed Results

Impairment of investments and assets Investments (113.6) (30.8) Equity-accounted investees – Far Southeast Gold Resources Incorporated ("FSE")1 (113.6) (30.8) Property, plant and equipment (391.4) (11.6) Peru cash-generating unit2 (63.1) — Tarkwa cash-generating unit3 (325.2) — Impairment of property, plant and equipment – other4 (3.1) (11.6) Impairment of investments and assets (505.0) (42.4) 1 During the year ended 31 December 2021, impairment indicators were identified as a result of the reduction in the share price of Lepanto and FSE was impaired by US$30.8m to its recoverable amount. The recoverable amount was based on the fair value less cost of disposal (“FVLCOD”) of the investment (level 2 of the fair value hierarchy). The FVLCOD was indirectly derived from the market value of Lepanto Consolidated Mining Company, being the 60% shareholder of FSE. During 2022, management was actively engaged in the process of disposing of FSE. The disposal process proved unsuccessful and no offers were received. Management’s assessment is that it is unlikely the investment could be sold for any value and wrote off the investment by US$113.6m to a carrying value of US$nil (level 3 of the fair value hierarchy). 2 For the year ended 31 December 2022, the Group recognised an impairment of US$63.1m in respect of the Peru cash-generating unit. The recoverable amount was based on its fair value lest cost of disposal (“FVLCOD”) calculated using a combination of the market (resource value) and the income approach (level 3 of the fair value hierarchy). The impairment is mainly due to an increase in the discount rate from 4.8% to 8.1% as a result of increases in the risk-free rate as well as inflationary cost pressures experiences in 2022. The recoverable amount at 31 December 2022 is US$477.1m using the following assumptions based on the 2022 life-of-mine plan: – Gold price: • 2023 – US$1,740 per ounce; • 2024 – US$1,730 per ounce; • 2025 – US$1,700 per ounce; • 2026 – US$1,650 per ounce; and • Long-term – US$1,620 per ounce – Copper price: • 2023 – US$7,700 per tonne; • 2024 – US$8,150 per tonne; • 2025 – US$8,150 per tonne; • 2026 – US$8,150 per tonne; and • Long-term – US$7,700 per ounce – Resource price of US$30 per ounce; – Resource ounces of 1.0 million ounces; – Life-of-mine: 8 years; and – Discount rate of 8.1%. 3 For the year ended 31 December 2022, the Group recognised an impairment of US$325.2m in respect of the Tarkwa cash-generating unit. The recoverable amount was based on its fair value lest cost of disposal (“FVLCOD”) calculated using a combination of the market (resource value) and the income approach (level 3 of the fair value hierarchy). The impairment is mainly due to an increase in the discount rate from 8.3% to 15.9% as a result of increases in the Ghana country risk premium and the risk-free rate as well as inflationary cost pressures experiences in 2022. The recoverable amount at 31 December 2022 is US$812.4m using the following assumptions based on the 2022 life-of-mine plan: – Gold price: • 2023 – US$1,740 per ounce; • 2024 – US$1,730 per ounce; • 2025 – US$1,700 per ounce; • 2026 – US$1,650 per ounce; and • Long-term – US$1,620 per ounce – Resource price of US$71 per ounce; – Resource ounces of 24.5 million ounces; – Life-of-mine: 13 years; and – Discount rate of 15.9%. 4 The US$3.1m in 2022 comprises US$2.5m (2021: US$1.6m) impairment of redundant assets in Peru, US$0.6m (2021: US$nil) impairment of redundant assets in Chile and US$nil (2021: US$10.0m) impairment of capitalised exploration costs at St Ives based on technical and economic parameters of various studies. 35 2022Gold Fields Reviewed Results

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 periods ended 31 December 2022 and 31 December 2021.

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 were market related discount rates and expected redemption period. The movement in the preference shares was as a result of fair value adjustments only. Oil and foreign exchange derivative contracts The fair values of these contracts are determined by using the applicable valuation models for each instrument type with the key inputs being forward prices, interest rates, volatilities and exchange rates. Loan advanced – contractor The fair value of the contractor loan approximates its carrying amount, determined using the discounted cash flow method and market related interest rates and is classified within Level 3 of the fair value hierarchy. Borrowings The five-year notes and the 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. 37 2022Gold Fields Reviewed Results

Reef yield decreased by 22% to 5.45g/t in the December quarter from 6.98g/t in the September quarter due to ore phasing and a decrease in ore mined grade. This was primarily as a result of lower grades in longhole stopes mined and an increase in waste mined. Total underground tonnes processed increased by 13% to 487kt in the December quarter from 432kt in the September quarter due to stockpile carryover. Surface tonnes processed decreased by 20% to 252kt in the December quarter from 315kt in the September quarter as treatment of surface tonnes was slowed down due to planned maintenance, cyanide shortages and Eskom Load Curtailment. Total Development decreased by 10% to 2,790 metres in the December quarter from 3,098 metres in the September quarter as fewer shifts were worked in the December quarter due to the planned maintenance shutdown. Secondary support installed decreased by 9% to 2,471 metres in the December quarter from 2,728 metres in the September quarter in line with reduced development and destress performance. Backfill increased by 18% to 98,070m3 in the December quarter from 83,017m3 in the September quarter due to the increase in the number of stopes available for backfilling. All-in cost increased by 24% to R804,575/kg (US$1,415/oz) in the December quarter from R649,812/kg (US$1,176/oz) in the September quarter mainly due to a decrease in gold sold and higher cost of sales before amortisation and depreciation, partially offset by lower capital expenditure. Total capital expenditure decreased by 4% to R474m (US$27m) in the December quarter from R492m (US$29m) in the September quarter. Sustaining capital expenditure decreased by 11% to R376m (US$21m) in the December quarter from R423m (US$25m) in the September quarter mainly due to lower spend at the Doornpoort Tailings Storage Facility expansion (commissioned end August) and the solar plant (commissioned end September). Non-sustaining capital expenditure increased by 43% to R98m (US$6m) in the December quarter from R69m (US$4m) in the September quarter due to higher spend on ore handling infrastructure as well as an increase in capital development meters achieved with New Mine Development.

Gold production increased by 4% to 139,600oz in the December quarter from 134,700oz in the September quarter due to higher tonnes milled. Yield decreased by 2% to 1.20g/t in the December quarter from 1.22g/t in the September quarter due to lower grades mined.

Strip ratio decreased by 4% to 4.6 in the December quarter from 4.8 in the September quarter. Gold mined decreased by 3% to 154.9koz in the December quarter from 159.1koz in the September quarter due to lower ore tonnes and grade mined. All-in cost increased by 12% to US$1,259/oz in the December quarter from US$1,126/oz in the September quarter due to higher capital expenditure and higher cost of sales before amortisation and depreciation, partially offset by higher ounces sold.

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 24 to 40 of the preliminary report, which comprise the condensed consolidated statement of financial position as at 31 December 2022 and the related condensed consolidated statements of comprehensive income, changes in equity and cash flows for year then ended, and selected explanatory notes. Directors’ Responsibility for the Interim Financial Statements The directors are responsible for the preparation and presentation of these condensed consolidated financial statements in accordance with the International Financial Reporting Standard, (IAS) 34 Interim Financial Reporting, the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee and Financial Pronouncements as issued by the Financial Reporting Standards Council 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 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 2410, Review of Interim 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 in a review are substantially less than and differ in nature from 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 accompanying condensed consolidated financial statements of Gold Fields Limited for the year ended 31 December 2022 are not prepared, in all material respects, in accordance with the International Financial Reporting Standard, (IAS) 34 Interim Financial Reporting, the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee and Financial Pronouncements as issued by the Financial Reporting Standards Council and the requirements of the Companies Act of South Africa. Other matter Unless stated otherwise, we have not reviewed future financial performance and expectations, guidance provided, non-IFRS measures, including adjusted or normalised financial information, production and sales volumes, yields, all-in sustaining costs, total all-in costs, other non-financial information, and information not required by IAS 34 Interim Financial Reporting, expressed by the directors in the accompanying condensed consolidated financial statements and accordingly do not express a conclusion thereon as part of this review.

To the Directors of Gold Fields Limited Report on the Assurance Engagement on the Compilation of Pro Forma Financial Information included in the Gold Fields 2022 Results Media Release. We have completed our assurance engagement to report on the compilation of the pro forma financial information of Gold Fields Limited (the “Company”) by the directors, which information constitutes pro forma financial information in terms of the JSE Limited (“JSE”) Listings Requirements. The pro forma financial information in the Gold Fields 2022 Media Release reviewed results for the year ended 31 December 2022 which incorporates the preliminary condensed consolidated financial statements for the year then ended (the “media release”), consist of normalised profit attributable to owners of the parent, normalised profit per share attributable to the owners of the parent, adjusted EBITDA, adjusted free cash flow, all-in sustaining costs, total all-in-costs, net debt (including and excluding lease liabilities), sustaining and non-sustaining capital expenditure and adjusted free cash flow from operations. The applicable criteria on the basis of which the directors have compiled the pro forma financial information are specified in the JSE Limited (JSE) Listings Requirements and described in the media release. The pro forma financial information has been compiled by the directors to illustrate the impact of: • normalised profit attributable to owners of the parent and normalised profit per share attributable to the owners of the parent is considered an important measure by the Company of the profit realised in the ordinary course of business. In addition, it forms the basis of the dividend pay-out policy; • adjusted EBITDA is required to be determined in terms of loan and revolving credit facilities agreements to evaluate compliance with debt covenants; • adjusted free cash flow is calculated as cash flow from operating activities less net capital expenditure, environmental payments, lease payments and redemption of Asanko preference shares; • all-in sustaining costs and total all-in-costs are presented to provide transparency into the costs associated with producing and selling an ounce of gold and is a common measure presented within the mining industry; • sustaining and non-sustaining capital expenditure is used in the determination of all-in-sustaining costs and total all-in-costs; • net debt (including and excluding lease liabilities) is used in the ratio to monitor the capital of the group; and • adjusted free cash flow from operations is calculated as cash flow from operating activities less net capital expenditure, environmental payments and lease payments from the mining operations. As part of this process, information about the Company’s financial position and financial performance has been extracted by the directors from the Company’s financial statements for the year ended 31 December 2022, on which a review report has been published. Directors' responsibility The directors of the Company are responsible for compiling the pro forma financial information on the basis of the applicable criteria specified in the JSE Listings Requirements and described in the media release. Our independence and quality control We have complied with the independence and other ethical requirements of Sections 290 and 291 of the Independent Regulatory Board for Auditors’ Code of Professional Conduct for Registered Auditors (Revised January 2018) and parts 1 and 3 of the Independent Regulatory Board for Auditors’ Code of Professional Conduct for Registered Auditors (Revised November 2018) (together the IRBA Codes), which are founded on fundamental principles of integrity, objectivity, professional competence and due care, confidentiality and professional behaviour. The IRBA Codes are consistent with the corresponding sections of the International Ethics Standards Board for Accountants’ Code of Ethics for Professional Accountants and the International Ethics Standards Board for Accountants’ International Code of Ethics for Professional Accountants (including International Independence Standards) respectively. 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 Control 1 and, accordingly, maintains a comprehensive system of quality control including documented policies and procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements. Reporting accountant’s responsibility Our responsibility is to express an opinion about whether the pro forma financial information has been compiled, in all material respects, by the directors on the basis of the applicable criteria specified in the JSE Listings Requirements and described in media release 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 JSE Listings Requirements. 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 pro forma financial information is solely to illustrate the impact of a significant event or transaction on unadjusted financial information of the company as if the event had occurred or the transaction had been undertaken at an earlier date selected for purposes of the illustration. Accordingly, we do not provide any assurance that the actual outcome of the event or transaction would have been as presented. 56 2022Gold Fields Reviewed Results

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 event or transaction, 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 judgment, having regard to our understanding of the nature of the Company, the event or transaction 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 specified by the JSE Listings Requirements and described in media release.
