Gemfields Encounters Major Production Challenge in 2026 Amid Tightening Supply Restrictions

Gemfields Faces Major Setbacks Amid Operational Challenges

In 2025, Gemfields encountered significant financial difficulties due to disruptions at its two primary mining sites. The company’s revenue dropped by 32% year-on-year to $135.1 million, and EBITDA plummeted by 85%, falling to $6.2 million from $43.2 million the previous year. These steep declines were largely attributed to reduced production levels and fewer auctions, marking a sharp contrast to the robust results seen just two years earlier.

Operational Failures and Security Issues

Several specific operational setbacks contributed to these results. At the Montepuez ruby mine in Mozambique, the recovery rate of high-quality rubies remained low, and a surge in illegal mining activity created hazardous and costly conditions. The situation escalated in October when two police officers lost their lives during a raid targeting illegal miners, highlighting the severity of the security risks and their direct impact on operations. Additionally, delays in launching a new $70 million processing facility pushed its expected start date into the first half of 2026, further limiting near-term production, despite some output beginning in September.

Financial Pressures Intensify

The financial impact was swift and severe. By mid-2025, Gemfields’ net debt had risen to $61.2 million, up from $44.4 million a year earlier. This increase was driven by a sharp decline in cash generation, with free cash flow before working capital adjustments swinging to a negative $22.1 million for the first half of 2025, compared to a positive $3.3 million in the same period the previous year. Heavy investment in the troubled Montepuez operation, combined with falling revenues, created a significant cash flow shortfall.

Impact on Kagem and Cost-Cutting Measures

Challenges extended to the Kagem emerald mine in Zambia, where weak auction outcomes and subdued global demand—especially from China—forced a halt in mining from January to May. This suspension further reduced Gemfields’ ability to generate revenue and meet market needs, compounding the difficulties at Montepuez. In response, management implemented a 17% reduction in group operating expenses and sold the Fabergé brand for $50 million to strengthen the company’s financial position.

Market Dynamics: Tight Supply Meets Shifting Demand

The colored gemstone market is currently marked by a clear divergence between supply constraints and demand trends for rubies and emeralds. Ruby prices have surged due to extreme scarcity, while the emerald market faces a more nuanced scenario, with robust demand threatened by new regulatory risks.

• Rubies: The market is seeing a pronounced split based on origin. In the second quarter of 2025, top-quality rubies from Myanmar experienced a 12.8% price increase quarter-over-quarter, fueled by limited supply from key mining areas like Mogok and sustained demand from luxury buyers. In contrast, rubies from African sources, including Montepuez, saw more modest price growth of 5.4% over the same period, underscoring the premium placed on the most sought-after stones.
• Emeralds: Prices are expected to climb 15% in 2025 due to strong global demand and restricted supply. The Kagem mine has historically contributed over $1 billion in revenue since 2009. However, the recent reintroduction of a 15% export tax on emeralds by the Zambian government poses a direct threat to this positive outlook, potentially discouraging investment and reducing export volumes.

Gemfields’ ability to benefit from these favorable market conditions is limited by ongoing operational delays. The crucial $70 million processing plant at Montepuez is now scheduled for commissioning in the first half of 2026, meaning production constraints will persist even as market prices for premium stones rise. This leaves the company struggling to meet demand despite favorable pricing trends.

Steps Toward Recovery: Key Milestones Ahead

Gemfields’ path to restoring balance between supply and demand depends on achieving several operational and financial objectives. The immediate focus is on improving liquidity and generating sustainable free cash flow after a year marked by steep revenue and EBITDA declines. Management’s recent actions—including a 17% reduction in operating costs, the $50 million sale of Fabergé, and a $30 million rights issue—were aimed at stabilizing the company’s finances. The next pivotal milestone is the commissioning of the new Montepuez processing plant, which is expected to ease supply bottlenecks and improve the company’s commodity position.

Addressing Fuel Supply Risks

Gemfields is also working to address vulnerabilities related to diesel supply. Rising geopolitical tensions in the Middle East have increased fuel costs and created supply uncertainties, posing a risk to the company’s diesel-dependent operations in Mozambique and Zambia. Management is exploring solutions such as alternative supply chains, expanded on-site storage, and operational changes to ensure production stability, especially as the new Montepuez plant comes online.

Upcoming Catalysts for Investors

• The company is set to publish its full-year results on March 26, which will provide a comprehensive view of its financial performance and confirm whether it recorded a loss as anticipated.
• The outcome of the strategic review of the Fabergé brand, sold last year to fund expansion, will also be closely watched. This review could signal further asset optimization efforts, with direct implications for Gemfields’ capital strategy and future direction.

Ultimately, Gemfields’ recovery depends on effective execution. The successful launch of the Montepuez processing plant is critical for increasing production and cash flow. At the same time, the company’s efforts to secure fuel supplies and its upcoming financial disclosures will be key indicators of whether it can stay on course toward a more balanced and sustainable future.
