Harmony Gold Mining Company Limited

Harmony Gold Mining Company Limited (NYSE: HMY) is a South Africa–based gold producer involved in mining and exploration activities. Its business spans the discovery, extraction, and processing of gold, operating through three primary divisions: South African underground mines, surface operations, and its international segment.

As per previous Kalkine’s Diversified Opportunities Report published on ‘HMY’ on Oct 23, 2025, Kalkine provided an ‘Buy’ stance on the stock at USD 17.82 based on fundamental analysis and the stock price has now moved up by ~ 22.67% since then.

Noted below are the details of support and resistance levels provided in our previous report:

Rationale:

• Production Softness and Grade Declines: Harmony faced planned but notable year-on-year production declines, with total gold output falling 8% to 12 128kg, primarily due to weaker performance at Moab Khotsong and Doornkop. Ground-condition challenges, fluctuating face grades, and shaft water-handling constraints resulted in lower underground production and a 6% decline in underground recovered grades. These operational constraints signal ongoing geological complexity and highlight the company’s sensitivity to operational disruptions at key assets.
• Rising Costs and Margin Pressure: Despite disciplined management, Harmony experienced significant cost inflation, with cash operating costs increasing 14% year-on-year to R928 439/kg and AISC rising 15% to R1 107 486/kg. Higher royalties, electricity inflation, and contractor expenses contributed to elevated cost levels. Although partially mitigated by strong gold prices, the underlying cost escalation poses a risk to margins and underscores the company’s exposure to South African mining inflation and regulatory-linked royalty volatility.
• Project Delays and Capital Intensity: The company’s major capital projects—particularly life-of-mine extensions at Mponeng, Moab Khotsong, and the 100MW solar project—faced contractor and trackless machinery challenges, delaying progress and increasing execution risk. Capital expenditure rose substantially by 31% to R2.87 billion, reflecting heavy investment needs that pressure short-term free cash flow and increase dependence on elevated metal prices to sustain returns.
• Integration Risks and Balance Sheet Exposure: While strategically important, Harmony’s acquisition of MAC Copper introduces integration and financing risks. The transaction required the partial drawdown of a USD 1.25 billion bridge loan, increasing financial exposure even though leverage remains within internal thresholds. Successfully integrating CSA into the portfolio, while simultaneously progressing capital-intensive projects like Eva Copper and Wafi-Golpu, raises complexity and heightens operational and financial execution challenges over the medium term.

Conclusion

Harmony Gold’s fundamentals reflect several operational and financial pressures, with planned but still meaningful production and grade declines, particularly at Moab Khotsong and other underground assets, weighing on overall output. The company also faces rising cost inflation, with cash costs and AISC increasing at double-digit rates due to higher royalties, electricity tariffs, and contractor expenses, tightening underlying margins despite supportive gold prices. In addition, delays across key capital projects and heavy capex requirements elevate execution risk and strain near-term cash flows, while the recent MAC Copper acquisition introduces integration and financing risks that add further balance-sheet and operational complexity.

Based on the notional gains, valuation downside and price action stance, a "Sell" recommendation on Harmony Gold Mining Company Limited (NYSE: HMY) has been given at the closing market price of USD 21.86 as on 23 December 2025.
