NAB 1H26 slides: underlying profit rises 6.4% despite revenue miss

National Australia Bank reported 1H26 underlying profit of $5.85 billion, up 6.4% ex notable items, but statutory profit fell 18.0% to $2.75 billion due to a $1.35 billion pre-tax software amortization charge. Revenue of $5.38 billion missed expectations by 48.8%, and the shares fell 1.88% to $39.08 despite a steady 85c dividend and CET1 capital of 11.65% (12.05% pro forma). Management highlighted progress in lending, deposits, AI deployment, and balance-sheet resilience, but the market reaction reflected concern over the earnings miss and outlook.

Analysis

The key market signal is not the reported earnings miss itself, but the widening gap between operating momentum and headline optics. That tends to compress near-term multiple expansion for banks because the market prices accounting uncertainty as if it were recurring, even when the charge is one-off; in practice, the stock often underreacts to normalized earnings power for 1-2 quarters before rerating when cleaner capital and cost data emerge. NAB’s stronger transaction deposit mix and proprietary home lending progress are the real margin lever, because they improve deposit beta resilience precisely when rate cuts or slower loan growth would otherwise pressure NIMs.

The second-order winner is not another bank, but capital-light competition in mortgage origination and SME payments. As NAB continues to wind down lower-return legacy mortgage assets and shift toward proprietary distribution, brokers and smaller lenders with weaker deposit franchises should face tighter economics over the next 6-12 months; the share gains in transaction accounts also imply more funding stickiness and less reliance on wholesale markets, which should matter if funding spreads widen. Conversely, the extra provisioning signals management sees sector stress concentrated in transport, logistics, regional, and agriculture—areas where working-capital demand can rise before credit losses do, so earnings risk is more about margin drag and risk-weighted asset inflation than a near-term blowout in bad debts.

The contrarian read is that the market may be over-discounting the charge while underpricing the strategic simplification. If product rationalization and AI-enabled servicing keep productivity savings on track, the bank can absorb a softer top line without sacrificing payout capacity; that makes the dividend more durable than headline profit suggests, especially with capital already comfortably above minimums. The main catalyst to reverse the discount is a cleaner second-half update showing cost saves flowing through while deposit growth remains above system—if that happens, the stock can re-rate before any macro improvement shows up in credit metrics.

Key Decisions for Investors

• Long NAB.AX on weakness over the next 1-3 weeks; target a 6-10% recovery if the market re-focuses on normalized earnings and capital strength, with stop loss on a sustained break below the recent post-earnings low.
• Pair trade: long NAB.AX / short a smaller Australian lender with weaker deposit funding and higher mortgage concentration for 3-6 months; the spread should widen if funding costs stay sticky and deposit franchise quality becomes the key differentiator.
• Buy NAB.AX 3-6 month call spreads rather than outright shares to express rerating upside with limited downside; best entry is after initial post-earnings volatility compresses.
• For a relative-value hedge, short an ASX-listed mortgage broker / non-bank credit exposure basket versus NAB.AX for 6-12 months; the thesis is that proprietary distribution and transaction deposits are worth more in a slower-growth environment.
• Set a catalyst monitor for the next half-year update: if productivity savings run-rate exceeds guidance and deposit growth stays above system, add to longs; if not, reduce as the valuation support from the dividend will likely be capped.
