Northern Star Resources (ASX:NST) is a gold producer with operations across Western Australia and Alaska, including KCGM at Kalgoorlie, Jundee, Thunderbox and Pogo. Its FY26 result showed higher Revenue and Earnings despite lower gold sales, while weaker free Cash Flow reflected a period of substantial Capital deployment. FY27 now places greater emphasis on the KCGM mill expansion, cost control and the timing of future Investment at the Hemi gold project.

FY26 Earnings Rise Despite Lower Gold Sales

For the year ended 30 June 2026, Northern Star sold 1,543 thousand ounces of gold, down 6 per cent from the prior year.

Despite the lower volume, revenue increased 19 per cent to A$7.6 billion as the average realised gold price rose to A$4,925 per ounce.

Underlying EBITDA increased 22 per cent to A$4.3 billion. Reported net profit after tax was A$1.7 billion, while underlying net profit reached A$1.8 billion.

The result highlights the impact of stronger realised gold prices on earnings, which more than offset the decline in ounces sold.

However, cost Inflation remained evident. All-in sustaining cost, or AISC, rose 25 per cent to A$2,698 per ounce.

AISC captures the ongoing cost of producing gold, including operating expenses and sustaining capital, and is a key measure of mine-level cost performance.

Cash Flow Reflects Heavy Capital Deployment

Free cash flow fell 56 per cent to A$627.7 million during FY26.

The weaker cash conversion came during a period of elevated investment across the group.

Northern Star deployed approximately A$2.9 billion of capital during the year, including A$1.035 billion on the KCGM mill expansion.

Cash and bullion stood at A$1.235 billion, while borrowings were A$1.395 billion, leaving net Debt of approximately A$160 million.

The contrast between higher earnings and lower free cash flow is therefore largely explained by the scale of capital investment.

For Northern Star Resources (ASX:NST), FY27 will remain capital intensive, meaning cash generation will depend not only on gold prices and production but also on the timing and execution of major projects.

KCGM Expansion Becomes a Central FY27 Test

The KCGM expansion is one of Northern Star's most important operating projects.

The expanded mill is intended to increase processing capacity to approximately 27 million tonnes per year.

Commissioning is under way, with lower-grade feed being used during the initial ramp-up phase.

The project cost is now expected to be between A$1.75 billion and A$1.81 billion, above the initial estimate of A$1.53 billion.

This increase makes execution particularly important because further delays or cost escalation could place additional pressure on capital efficiency and free cash flow.

The key operational challenge is to bring the expanded processing system up to planned throughput while maintaining acceptable recovery, reliability and cost performance.

FY27 Guidance Points to Higher Costs

Northern Star has guided to gold sales of between 1,500 thousand and 1,650 thousand ounces in FY27.

Group AISC is expected to increase to between A$3,050 and A$3,450 per ounce, compared with A$2,698 per ounce in FY26.

The higher cost range indicates that FY27 will be a more expensive operating year even if production remains broadly in line with recent levels.

Capital investment is guided at between A$2,550 million and A$2,935 million.

These figures mean Northern Star enters FY27 with both elevated operating costs and significant capital commitments.

The ability to manage these expenditures while maintaining balance-sheet flexibility will be an important part of the year's financial performance.

Higher Dividend Follows FY26 Earnings

Northern Star declared a fully franked final dividend of 30 cents per share.

Together with the 25-cent interim dividend, total FY26 dividends amounted to 55 cents per share.

The final dividend had a Record Date of 10 September 2026 and is scheduled for payment on 15 October 2026.

The full-year dividend represented approximately 27 per cent of cash earnings.

The payout sits alongside substantial investment requirements, particularly at KCGM and across the broader growth portfolio.

Capital allocation will therefore remain a balance between dividends, project development and maintaining financial flexibility.

Hemi Adds a Longer-Term Development Option

Northern Star also holds the Hemi gold project in the Pilbara following its Acquisition of De Grey Mining.

Hemi contains 13.2 million ounces of mineral resources and 5.5 million ounces of ore reserves.

The project remains at a development stage, with a final investment decision targeted for late FY27.

Construction is estimated to take approximately 2.5 years following that decision.

Before reaching the investment stage, the project must continue to progress through technical, environmental and operational work, including managed aquifer recharge trials.

Hemi therefore represents a significant longer-term growth opportunity, but it also introduces another potential capital requirement beyond the KCGM expansion.

Leadership Changes Add an Execution Dimension

Governance and Leadership developments are also relevant entering FY27.

Suresh Vadnagra is due to commence as chief executive on 5 October 2026.

The company has also appointed Jeff Quartermaine and Terry Bowen as directors.

These changes come at a time when Northern Star is managing several major strategic priorities, including the KCGM ramp-up, FY27 cost pressures and the development pathway for Hemi.

A change in chief executive during a capital-intensive period places additional focus on operational continuity and execution.

Shareholder Engagement Remains in Focus

Northern Star has also been engaged with Elliott Investment Management, which disclosed a 5.35 per cent economic interest through cash-settled swaps during July 2026.

The board subsequently stated that it had declined proposals to appoint Elliott nominees under a pre-agreed framework.

The engagement introduces an additional governance consideration alongside the company's operational programme.

Further developments could influence board composition or strategic discussions, although the core operating priorities remain centred on production, costs, capital allocation and project delivery.

Key Risks and Uncertainties

The KCGM expansion carries execution risk because the project is still progressing through commissioning and ramp-up.

Throughput, recovery rates, reliability and capital costs can differ from initial expectations during this phase.

Cost inflation is another major concern. FY27 AISC guidance is materially higher than the FY26 outcome, which could reduce margins if gold prices weaken.

The company also remains exposed to movements in the Australian dollar and the gold price, both of which can materially affect revenue and profitability.

Hemi adds longer-term development potential but also creates future funding and project execution requirements.

Management transition and ongoing Shareholder engagement provide additional governance considerations during a period of elevated investment.

What to Watch in FY27

The start of Suresh Vadnagra's tenure as chief executive on 5 October 2026 will be an early milestone.

The final FY26 dividend is scheduled for payment on 15 October 2026.

Operationally, attention will remain on the KCGM ramp-up and whether the expanded mill progresses toward its planned 27 million tonnes per year processing rate.

Completion of KCGM Stage II consolidation, targeted for later in the first half of FY27, will also be significant.

Northern Star's quarterly updates will provide further information on production, AISC and Capital Expenditure against FY27 guidance.

Progress at Hemi, including managed aquifer recharge trials and work toward a final investment decision, will remain another important area to monitor.

For Northern Star Resources (ASX:NST), FY26 delivered higher earnings, but FY27 places the emphasis firmly on execution. The main test will be whether KCGM can move through ramp-up while the group controls costs and preserves cash generation during another heavy investment year.
