Is BHP Undervalued in 2026? Full DCF and Graham Analysis

Why BHP?

BHP Group is the largest company on the ASX by market cap and one of the most widely held stocks by Australian retail investors. Every superannuation fund owns it. Every dividend-focused investor has considered it.

But popularity does not equal value. Here is a complete, data-driven analysis.

Dividend Yield

Important: BHP reports in USD but trades in AUD. Always convert using current AUD/USD exchange rate. The numbers below use approximate AUD equivalents.

The Graham Number Analysis

Graham Number = √(22.5 × EPS × BVPS)

Using normalised mid-cycle earnings (not peak): - Normalised EPS: ~$3.80 AUD (5-year average) - Book Value Per Share: ~$17.20 AUD - Graham Number ≈ $38.40 AUD

At ~$43, BHP trades at a modest 12% premium to its Graham Number. There is limited margin of safety at current prices on a pure Graham basis.

⚡ Always normalise BHP earnings. At peak iron ore ($160/t), EPS might be $6.50, giving a Graham Number of $50+. At trough ($70/t), EPS drops to $1.80 and Graham Number falls to ~$26. Use 5-year average EPS to avoid being fooled by the commodity cycle.

DCF Valuation — Conservative Case

For a mature commodity business, conservative DCF assumptions are essential:

Input	Value	Rationale
Base FCF	~$8B USD	Normalised free cash flow
Growth Rate	2-3%	GDP-linked commodity demand
Discount Rate	10%	Required return
Terminal Growth	2%	Long-term inflation proxy

BHP — Normalised FCF vs Commodity Cycle Impact ($B USD, approximate)

At these conservative inputs, DCF fair value is approximately $38-42 AUD per share. This broadly confirms the Graham Number estimate.

DDM Analysis — Dividend Perspective

BHP pays a significant dividend, typically 50-60% of earnings. Australian investors receive fully franked dividends, boosting the effective yield:

Cash dividend: ~$2.20 AUD per share (~5.1% yield)
Franking credit: ~$0.94 per share
Grossed-up dividend: ~$3.14 per share
Grossed-up yield: ~7.3%

DDM value (using 3% growth, 10% discount): ~$44.80 AUD

This is slightly above current prices, suggesting the market is pricing BHP fairly on income metrics.

Key Risks to the Thesis

Iron ore concentration: Over 50% of BHP earnings come from iron ore. China consumes ~70% of global seaborne iron ore for steel production. Any significant Chinese construction slowdown hits BHP disproportionately.

Commodity price volatility: Iron ore has ranged from $50/t (2015) to $230/t (2021). A return to mid-$80s (plausible in a slowdown) would roughly halve earnings.

Capex demands: BHP's copper growth projects (Olympic Dam, Jansen potash) require massive capital. This competes with shareholder returns.

AUD/USD exposure: BHP sells in USD. A rising AUD reduces returns to Australian shareholders.

Bottom Line: Fairly Priced, Not Cheap

At ~$43 AUD, BHP is trading close to normalised fair value on all four models: - Graham Number: ~$38 (BHP slightly above) - DCF: ~$38-42 (near fair value) - DDM: ~$44 (slightly below) - EPV: ~$32-36 (above — growth premium being paid)

Target entry: Patient value investors should wait for a 15-20% pullback to the $33-37 range, which would provide a genuine margin of safety. This level typically appears during iron ore corrections or broad market selloffs.
