BHP GROUP LIMITED (BHP) — Investment Research Note
Executive Summary
BHP is the world's largest diversified miner, producing copper (~39% of EBITDA), iron ore (~56%), and steelmaking coal/energy coal, with growth optionality in potash (Jansen, Canada) and copper (Vicuña JV, OZ Minerals/Copper South Australia). Across the five-year window covered, the trajectory has been: very strong FY21–FY22 (iron ore boom, peak underlying EBITDA ~$35bn FY21), softening in FY23–FY25 as iron ore prices normalised to the US$80–100/t range while copper volumes recovered (HY25 EBITDA $12.4bn, –11% YoY) 2025-02-18 half-year, 2022-02-15 half-year. The single most important point for valuation today is that BHP is moving from being primarily an iron ore cash machine to a more capital-hungry copper/potash growth company, with ~65% of medium-term capex earmarked for future-facing commodities and $10–11bn p.a. capex versus a normalised free cash flow that is sensitive to a softer iron ore price deck.
Fair Value Estimate
- Fair value range: £19.00 – £24.00 per share (implied market cap ~£96bn – £122bn at ~5,072m basic shares outstanding 2025-02-18 half-year, EPS denominator).
- Methodology: Blended EV/EBITDA on mid-cycle earnings, cross-checked with normalised P/E.
- Mid-cycle Underlying EBITDA assumption ~$25bn (between trough HY25 annualised ~$24bn and peak FY21 ~$35bn) 2025-02-18 half-year; 2022-02-15 half-year.
- Applied 5.5x – 7.0x EV/EBITDA multiple (consistent range for Tier-1 diversified miners with BHP's quality but cyclical earnings) → EV $137bn – $175bn.
- Less net debt of $11.8bn (Dec 2024) plus Samarco-related obligations of $5.9bn (treated as debt-like; FY26e cash impact alone ~$3.9bn) 2025-02-18 half-year, note 9.
- Equity value: ~$120bn – $157bn → at GBP/USD ≈ 1.27, £94bn – £124bn.
- Cross-check P/E: HY25 underlying EPS 100.2¢ annualised ≈ 200¢ (~£1.58); at 12–14x → £19.0 – £22.0.
- Comparison to current market cap of £147,365.4m: mid-point fair value ~£109bn implies the stock is trading ~26% above fair value.
- Absolute downside: ~–26% (range: ~–17% to ~–35%).
Sector Context
- Sector classification confirmed: Basic Resources / Basic Materials (Mining – Diversified).
- BHP's quality/leverage profile is above typical sector peers: A1/A credit ratings, gearing 19.2%, net debt/EBITDA 0.4x, EBITDA margin 51% 2025-02-18 half-year. WAIO is the lowest-cost major iron ore producer globally (C1 $17.50/t). Growth profile is in line with peers (modest organic growth pivoting to copper).
- Listed UK peers: Rio Tinto (most directly comparable diversified), Anglo American (more PGM/copper tilted), Glencore (commodity trading + coal/copper).
Investment Thesis (3 bullets)
- Lowest-cost, long-life iron ore franchise underpins through-cycle cash generation. WAIO held its position as the lowest-cost major iron ore producer globally for the fifth consecutive year at C1 US$17.50/t, and has plans to grow to >305 Mtpa over the medium term with regulatory approval to expand to 330 Mtpa already obtained 2025-02-18 half-year; 2022-01-19 operational review.
- Copper growth pipeline materially re-weights the portfolio toward future-facing commodities. Copper EBITDA contribution jumped to 39% of group EBITDA in HY25 (vs 25% prior year), with a $2.0bn Vicuña JV (Filo del Sol + Josemaria) completed Jan 2025, aspirations to grow Copper South Australia to >500ktpa, and Escondida growth options with attractive ~15–19% IRRs at consensus prices 2025-01-15 Filo acquisition; 2025-02-18 half-year.
- Disciplined capital framework with consistent shareholder returns. ~$50bn returned to shareholders since 1 Jan 2021, including the HY25 interim dividend of 50¢/share at a 50% payout ratio; balance sheet remains conservatively geared with Moody's A1/Fitch A ratings 2025-02-18 half-year.
Key Risks (3 bullets)
- Iron ore price risk as Chinese steel production plateaus. BHP itself flags China steel production has likely plateaued around 1Bt and pig iron output is expected to decline; new African supply (Simandou) is expected from 2026, with cost support estimated only in the US$80–100/t range. Realised iron ore price fell 22% YoY in HY25, taking $2.7bn off WAIO EBITDA 2025-02-18 half-year.
- Samarco settlement obligations create multi-year cash drag. Confirmed ~$3.9bn cash outflow in FY26 and ~$1.6bn in FY27 (100% basis) for the ratified settlement, with secondary obligor exposure if Samarco cannot fund. Ongoing UK group action and Australian class action are unprovisioned contingent liabilities 2025-02-18 half-year, note 9.
- Capital intensity is rising as iron ore tailwind fades. Group capex guided to ~$10bn in FY25 and ~$11bn p.a. medium-term, while ROCE has already fallen from 26.4% to 20.4% YoY; Western Australia Nickel suspended with $2.5bn impairment in FY24 illustrates execution/commodity-cycle risk on growth bets 2025-02-18 half-year; 2024-02-15 exceptional items update.
Value-trap Signals
- Rising debt with declining EBITDA: Net debt up to $11.8bn from $9.1bn at FY24, while underlying EBITDA fell 11% YoY 2025-02-18 half-year. Not yet structural, but worth monitoring.
- Falling ROCE (26.4% → 20.4%) at the same time capex steps up — classic late-cycle pattern for a miner pivoting from harvest to growth.
- Queensland royalty regime has rendered BMA uneconomic for growth investment ("we will not be investing in any further growth at BMA"); coal is contracting 2025-02-18 half-year. Not a value trap per se but a permanent earnings pressure on the coal segment.
- Dividend trajectory has declined materially: interim DPS 150¢ (Feb 2022) → 90¢ (Feb 2023) → 72¢ (Feb 2024) → 50¢ (Feb 2025), a –67% reduction reflecting normalising commodity prices.
Conviction
Conviction: 3 (Moderate) — confident the stock is currently expensive relative to mid-cycle fundamentals, but valuation is highly sensitive to commodity price assumptions.
Anchors (support confidence):
- Disclosure quality is exceptional — segment-by-segment EBITDA waterfalls, unit cost reconciliations, sensitivity to FX, and explicit medium-term guidance.
- Multiple methodologies (EV/EBITDA on mid-cycle earnings, normalised P/E) converge on a similar fair value range of ~£19–24.
- Reliable, audited financials (EY) with no significant restatements over the period.
Limiters (reduce confidence):
- Cyclical earnings — a sustained iron ore price above $110/t or copper above $5/lb could justify materially higher valuation; the fair value is essentially a bet on mean reversion in iron ore.
- Samarco contingent liabilities (UK group action, criminal proceedings) are unquantifiable downside that could pressure valuation further.
