BHP Price Target Trimmed, As Analyst See’s Downside From Here

BHP shares (ASX: BHP) bumped into the first major obstacle in a while, with the share price pulling back from ATHs on the week to close Friday down 5.6% at A$61.40. The A$65 level has proven a tough hold in recent attempts, yet a breakout had appeared to be holding prior to a fundamental shift, and now an analyst note that suggests plenty of downside.

BHP Group’s ambitious push into potash fertilisers has hit a major cost hurdle, prompting Barclays to trim its price target on the mining giant’s London-listed shares to 2,750 pence from 2,770 pence while maintaining an Equal Weight rating. The move comes after BHP disclosed a 42 per cent capital expenditure overrun on its Jansen Stage 2 project in Saskatchewan, Canada, alongside a substantial US$2.3 billion write-down that analysts say materially erodes the project’s expected returns.

To get a clearer view on what this new price target means here on the ASX, BHP’s London-listed shares closed at 3,183 pence on Friday, creating a notable disconnect with Barclays’ revised fair value estimate. The gap of approximately 433 pence, or roughly 14 per cent downside from current levels, suggests markets may be pricing in more optimism around BHP’s diversification strategy than the broker’s fundamental analysis supports. The modest 20-pence reduction in Barclays’ target appears small in absolute terms, yet the analyst’s explicit citation of deteriorating project economics signals a recalibration of risk-adjusted returns across BHP’s growth portfolio.

The valuation tension reflects broader uncertainty about whether BHP’s premium multiple can be sustained as cost pressures mount on its flagship diversification asset. While the Equal Weight rating indicates Barclays still views BHP as fundamentally sound relative to sector peers, the firm’s commentary that Jansen’s economics are being “further eroded” underscores growing Street caution about execution risk outside the company’s core iron ore and copper operations.

Jansen Costs Surge

On 18 June 2026, BHP revealed that total investment for Jansen Stage 2 had climbed from an originally sanctioned US$4.9 billion to approximately US$6.9 billion, a US$2.0 billion increase representing a 42 per cent capex overrun. First production from the expanded potash facility has been pushed back to late fiscal 2031, roughly two years later than earlier market expectations around fiscal 2029.

The cost blow-out stems from a combination of factors including persistent labour shortages in Saskatchewan’s tight construction market, elevated materials inflation, and productivity challenges in executing large-scale underground mining infrastructure. BHP management has framed the revised estimates as a deliberate effort to front-load risk recognition, aiming to avoid further major revisions once full-scale construction accelerates.

As a consequence of the higher capital requirements and extended timeline, BHP expects to record an impairment charge of approximately US$2.3 billion on the Jansen asset in its fiscal 2026 reporting. The write-down reflects updated discounted cash flow assumptions that incorporate both the increased upfront investment and the delayed revenue generation, effectively signalling that previously capitalised balance sheet values are no longer supported under current project economics.

Despite the setback, BHP maintains that the combined Jansen operation will still rank at the low end of the global potash cost curve once fully ramped. The company projects operating unit costs of approximately US$114 to US$130 per tonne FOB Vancouver, consistent with earlier guidance despite the capital creep. Management argues this cost positioning preserves long-term value even as near-term returns have deteriorated.

The revised post-tax internal rate of return, calculated using consensus potash prices of around US$330 per tonne over the fiscal 2031 to fiscal 2041 period, has declined materially though BHP has not disclosed the precise updated IRR figure. The company continues to emphasise Jansen’s strategic importance as a multi-decade platform with combined Stage 1 and Stage 2 capacity targeting approximately 8 to 8.5 million tonnes per annum, with optionality for further expansion stages if market conditions warrant.

What To Watch

BHP’s near-term challenge lies in demonstrating that the Jansen cost overruns represent a final reset rather than the latest instalment in an ongoing pattern of underestimation. Markets will scrutinise upcoming project updates and quarterly reports for evidence that construction execution is stabilising and that no further material cost escalations are on the horizon.

The company’s substantial balance sheet and low leverage provide a buffer to absorb the US$2.3 billion impairment without threatening dividend sustainability or credit ratings. However, the reputational cost of repeated project revisions may linger, potentially constraining BHP’s ability to secure premium valuations for future growth initiatives until it rebuilds credibility on capital allocation and execution.

For bulls, the long-term thesis rests on Jansen eventually delivering low-cost potash production into a structurally attractive market, with the write-down viewed as the price of securing a multi-decade strategic asset. For bears, the 42 per cent overrun and delayed cash flows underscore the risks of venturing beyond core competencies, justifying a more conservative valuation multiple until BHP proves it can deliver on its diversification ambitions without further value destruction.

Whilst Barclays’ price target cut in and of itself was small, the perceived downside from here is what is worth watching. Whilst broker sentiment is not decisive, when combined with fundamental setbacks, it can have an impact on the stock. We have seen part of that initially on Friday, but there remains plenty to watch into the new week. Bulls will need to see strength around the psychologically important A$60 level should a move lower materialise, whilst bears will be looking to see cracks emerge in buying appetite.
