Northern Star rejects Gold Fields’ $27 billion takeover proposal  

Northern Star Resources, Australia’s top gold producer, has rejected an unsolicited A$38.7 billion ($27.1 billion) takeover proposal from South Africa’s Gold Fields, pushing back against a deal that would combine two major gold producers and create the world’s second-largest gold miner by production. 

The proposal would have paid Northern Star shareholders 0.3125 new Gold Fields shares plus A$7.25 (5.08) in cash for each Northern Star share. Based on Gold Fields’ Sept. 11 closing price, the offer implied A$27 ($18.92) per share and a 22% premium to Northern Star’s pre-offer closing price.

A bid under pressure 

The value of Gold Fields’ offer has since fallen with its share price. Based on the Sept. 25 close, the proposal was worth about A$25.19 ($17.67) per Northern Star share. That represents a 14% premium to Northern Star’s previous close, compared with the roughly 22% premium when the proposal was first made.

Northern Star Chairman Michael Chaney said the company considered the proposal materially below the fundamental value of its portfolio and poorly timed. The Perth-based miner also objected to the substantial equity component, saying it would leave shareholders with greater exposure to jurisdictional risks associated with Gold Fields.

Activist pressure builds 

The rejection comes as Northern Star faces pressure from activist investor Elliott Investment Management, which has called for a strategic review and argued that the company could create more value through alternatives including a sale. Elliott disclosed a 6.2% stake and has pushed for greater focus on shareholder returns. 

Northern Star appointed a new chief executive in July amid that pressure. Elliott partner John Pike said Monday that the investor sees significant potential for value creation and that any transaction should reflect that potential, adding pressure on the board to consider serious approaches.

Gold Fields keeps talking 

Gold Fields said it had held discussions with Northern Star for about six months before submitting its proposal. The South African miner said the combination would offer strategic and financial benefits, while leaving Northern Star shareholders with about a 33% stake in the enlarged company and creating a secondary Australian listing. 

Gold Fields has estimated $4 billion to $5 billion in potential corporate, operational and portfolio optimization synergies. The combined group would produce about 4.1 million ounces of gold annually, with roughly 80% of production coming from Australia, North America and Chile.

Fight over gold assets 

The proposed combination would deepen Gold Fields’ presence in Western Australia, where both companies operate near Kalgoorlie. Northern Star runs the Super Pit, one of Australia’s largest gold mines, while Gold Fields expanded its Australian footprint through its A$3.7 billion ($2.59 billion) acquisition of Gold Road Resources last year. 

Northern Star said the proposal arrived before important growth catalysts, including the commissioning and ramp-up of the Fimiston Mill. Gold Fields, meanwhile, remains open to discussions with Northern Star’s board, leaving the prospect of renewed takeover negotiations as investors assess whether the two miners can bridge the valuation gap.

Gold Fields enters from strength

Gold Fields’ pursuit comes after a strong period for the gold producer. Its profit attributable to owners rose 81% to $1.85 billion in the first half of 2026, from $1.03 billion a year earlier, as higher gold prices and stronger production lifted financial results. 

Gold Fields is a globally diversified gold producer with eight operating mines spanning South Africa, Australia, Ghana, Chile and Peru. Its geographically diverse portfolio gives the company exposure to several of the world’s major gold-producing regions.

Northern Star Resources is a major Australian gold producer with mining and exploration operations in Western Australia and Alaska. The company is listed on the Australian Securities Exchange.
