2025 Integrated annual report

Operational excellence

In a financial year characterised by lower commodity prices, we demonstrated the benefit of our diversified portfolio. This positions ARM well, as we focus on operating a competitive business in a challenging sector.

In summary:

  • ARM Ferrous headline earnings decreased by 31% to R3.5 billion (F2024: R5.1 billion), partially offset by a 120% increase in headline earnings in the manganese division
  • ARM Platinum headline earnings declined 42% to a headline loss of R1.3 billion (F2024: R910 million loss), largely due to the drop in average PGM basket price and high fixed costs associated with the early ounce production at Bokoni (discussed on page 77)
  • ARM Coal headline earnings were down 88% to R47 million (F2024: R391 million), driven by the reduction in the realised coal price.

In this period of high volatility, we focus on what we can control: ensuring zero harm to all our employees, achieving quality production volumes, managing costs, and improving productivity.

Strategic focus areas

To navigate uncertain economic cycles and ensure maximum value from our portfolio of competitive assets, we are focused on:

  • Operating globally competitive and profitable mines
  • Decisive action on underperforming assets
  • Disciplined capital allocation
  • Collaborate with key stakeholders to optimise logistics and infrastructure constraints
  • Maintain a robust balance sheet by generating profits, reducing costs and deferring non-essential capital expenditure
  • Pursue value-enhancing growth opportunities.

The period under review was impacted by ongoing geopolitical tensions, commodity volatility and economic uncertainty, exacerbated by changing tariff policies from the USA. In South Africa, there was some progress on pervasive economic and infrastructural issues:

  • The Department of Electricity and Energy is stabilising Eskom and accelerating the use of renewable energy across the country
  • Transnet is working with the private sector and industry bodies to address rail and port constraints.

We remain focused on ensuring our operations perform optimally, conserving cash by deferring projects where feasible, and evaluating organic or acquisitive growth opportunities.

Creating sustainable value

In F2025, ARM created total value of R12.2 billion (F2024: R12.4 billion). Of this, R2.6 billion was paid to shareholders as dividends and around R500 million accrued to providers of capital. We also reinvested R200 million in the group to support our continued growth.

The financial and operational reviews on pages 62 to 90 detail our performance for the year, while corporate actions in F2025 are summarised on page 11. My review focuses on progress against strategic objectives more broadly and the significant infrastructure challenges our operations continue to face.

Safety performance

We are resolute in ensuring a safe and healthy working environment for all employees and achieving our goal of zero harm. Underscoring our commitment to this goal, safety is a key performance indicator (KPI) in executive remuneration.

Regrettably, we recorded three fatalities in F2025 (F2024: one), following incidents at Bokoni Platinum Mine, Modikwa Platinum Mine and Black Rock Mine. We extend our deepest condolences to their family members, friends and colleagues. Support and counselling were offered to family members and all affected employees through our employee assistance programme. We are working hard to strengthen safety measures and ensure our people are safe and return home unharmed every day.

Demonstrating that our goal of zero harm is achievable, safety highlights during the year included:

  • Two Rivers Platinum Mine – 3 million fatality-free shifts over two years
  • Khumani Mine – 6 million fatality-free shifts over nine years
  • Beeshoek Mine – 6 million fatality-free shifts over 22 years.

In addition, we prioritise the health and wellbeing of our people. We also continued to assist our host communities, suppliers and other stakeholders, as detailed in the ESG report.

PGM projects status

Two Rivers Merensky project

Due to the downturn in PGM prices, the Two Rivers Merensky project was placed on care and maintenance in July 2024. The construction of the Merensky concentrator plant and development of the first two mining levels are complete.

We are re-evaluating the potential restart of the Merensky project, depending on the outcome of the definitive feasibility study, and an evaluation of whether the recovery in PGM prices can be sustained.

Bokoni Platinum Mine

Milling and stoping operations at Bokoni were suspended at the end of F2025, as the mining and milling capacity was insufficient to offset fixed costs and sustain profitability. Ore-reserve development is advancing to support a phased ramp-up to a 240 000 tonnes per month (tpm) production rate, regarded as the optimum throughput to unlock economies of scale and deliver sustainable returns.

This strategy is anchored by Bokoni's large, high-grade Mineral Resource, which positions the mine competitively on the cost curve at steady-state production. To accelerate cash generation and reduce funding needs, the existing 60 000tpm concentrator will be restarted ahead of the new concentrator plant, with timing carefully sequenced to ore availability and ramp-up milestones.

We remain confident that this strategy is the right approach to unlock value from Bokoni's exceptional resource base while exercising disciplined capital allocation, considering ongoing commodity price uncertainty.

Tailings storage facilities (TSFs)

Our TSF management policy and standard, which align with the ICMM's Global Industry Standard on Tailings Management (GISTM), have been implemented at all our platinum and ferrous operations. GISTM is a global benchmark for achieving strong social, environmental and technical outcomes in managing TSFs, with the goal of zero harm to people and the environment. ARM and its joint-venture partners have adopted GISTM at all mines, covering 13 active TSFs.

ARM submitted its GISTM conformance results and public disclosure document for all its TSFs classified as "low" and "extreme" in August 2025. Operational reviews from page 62 provide more details, and our GISTM report is available on our website.

Corporate actions

In F2025, ARM concluded corporate actions in line with our focus on investing in growth and our existing business.

Hedging collar transaction over 24% of our equity in Harmony

We implemented a hedging collar transaction involving 18 million shares in Harmony Gold, representing 24% of ARM's equity in that company. The collar and related arrangements give ARM access to future funding on efficient terms while retaining partial upside exposure. The structure includes a put option at R234.85 and a call option at R562.40, both maturing in June 2030.

ARM remains fully committed to Harmony as a strategic investment and remains confident in Harmony and its management's ability to drive growth and value for its shareholders.

Share buyback

In accordance with the general authority granted by shareholders at ARM's annual general meeting in December 2024, we have cumulatively repurchased and cancelled 3 239 681 ordinary shares, at an average price of R154.27 per share, totalling R499.8 million.

Additionally, ARM's subsidiary, Opilac, distributed 12 717 328 treasury shares in specie back to ARM, which were cancelled and delisted. These actions reduced the total issued share capital by 7% to 208 710 769 ordinary shares. The cancellation of the treasury shares has no impact on the earnings per share and headline earnings per share of ARM.

Refer to SENS announcement on 20 June 2025 for details.

Closure of Cato Ridge Works and Alloys, disposal of Assmang's interest in Sakura

ARM has announced a series of strategic transactions involving its 50% stake in the joint venture, Assmang. These include the permanent closure of the Cato Ridge Works plant from 31 August 2025. Assmang will also sell land, properties and houses in Cato Ridge, with part of the land designated for community benefit.

Additionally, Assmang will dispose of its stake in Sakura Ferroalloys to Assore, resulting in a cash distribution of R900 million to ARM.

Refer to SENS announcement on 11 June 2025 for details.

Surge Copper

ARM has entered into a subscription agreement to acquire 25.8 million common shares of Surge Copper Corp through a non-brokered private placement for some C$4.5 million.

This follows ARM's earlier exercise of its rights under an investor rights agreement, where it purchased 1.6 million shares for C$0.24 million in a top-up offering. Prior to these transactions, ARM held 43.0 million shares (13.4% of Surge's issued shares). On completion of the private placement, its shareholding will increase to 68.7 million shares, representing 19.9% of the company on a non-diluted basis.

Surge owns a large, contiguous mineral claim package that contains copper and other metals which are important inputs to the low-carbon energy transition and associated electrification technologies. It has made strong progress on the prefeasibility study, which remains on track for completion in 2026.

Refer to SENS announcement on 15 August 2025 for details.

Looking ahead to F2026

GGlobal economic growth is projected to improve slightly for the 2025 calendar year and reach 3.1% in 2026, according to the International Monetary Fund (IMF). Elevated uncertainty and geopolitical tensions could also weigh on economic activity and disrupt global supply chains.

South Africa's economic outlook is characterised by a mix of modest growth, persistent challenges and significant risks. The 2025 IMF GDP growth forecast has been revised down to 0.9%, largely attributable to ongoing issues with freight capacity and infrastructure. The country faces various risks, including the potential for a rebound in US tariffs, which could negatively impact trade and growth, and exacerbate the already-high unemployment rate.

China's iron ore imports are expected to decrease slightly this year but recover over the next few years. In the medium term, the Simandou Mine in Guinea is projected to significantly increase global supply, which will likely lead to a decline in iron ore prices.

The PGM market has seen strong sales in the first half of the year, especially in China and North America. The imposition of US tariffs poses a risk to PGM prices for the rest of the year, but this could be partially mitigated by renewed interest in internal combustion engines and the lower than expected penetration of battery electric vehicles in the US market.

The coal market has shifted from the tight market conditions of 2022 to oversupply in 2025, driven by weaker oil and gas demand, increased nuclear restarts in Japan, renewable energy growth in Asia, and strong Chinese exports. This has led to higher inventories and falling prices. A material rebound in prices is not expected before 2027.

The manganese ore market has shifted from a period of tight supply and high prices to oversupply and weak demand. Market sentiment remains bearish, with production cuts and potential stimulus measures in China seen as key to rebalancing the market and restoring price stability.

Despite ongoing commodity market volatility, ARM remains optimistic about the medium to long-term outlook for the mining sector. Encouraging signs of recovery in key markets, improving financial conditions, and infrastructure investment reinforce our view. With a portfolio of quality, long-life assets and world-class orebodies, ARM is well-positioned to navigate the uncertain commodity and market environment. We continue to strengthen resilience by driving productivity, improving cost efficiency, and applying disciplined capital allocation.
