National Australia Bank has delivered a 80.1% share price gain over the past 5 years, which naturally raises the question of whether that kind of performance is backed by the returns it earns on its capital or whether investors are paying up for something else. With the stock now around A$38.54, the issue is how well the current price lines up with what the business can realistically earn on the equity and capital it deploys.
-
The 80.1% return over 5 years puts real weight on the idea that NAB's track record of earning on its capital can justify a meaningfully higher equity value than it had in the past.
-
Management's decision to bring in McKinsey and KPMG to review the corporate and institutional bank may support shifts in how capital is allocated between business lines and could influence the future level and stability of returns that underpin any intrinsic value estimate.

Does National Australia Bank Look Fairly Valued on Excess Returns?
The Excess Returns model looks at whether National Australia Bank is earning more on shareholder equity than it costs to fund that equity. Here, the bank is working off an average return on equity of 11.17% against a cost of equity of A$1.70 per share and a calculated excess return of A$0.70 per share. With a book value of A$19.78 per share and a stable book value estimate of A$21.54 per share, the framework assumes the franchise keeps generating a return spread that supports earnings power over time.
Stable EPS is pegged at A$2.41 per share, based on analyst estimates for return on equity, and feeds into a dividend profile that the separate dividend model treats as capable of modest growth. The Excess Returns workup suggests the estimated intrinsic value is broadly in line with the current A$38.54 share price, which points to a market that already prices in this return profile. Because NAB has brought in McKinsey and KPMG to review the corporate and institutional bank, any shift in capital allocation or risk appetite in that division could change the return spread that underpins this equilibrium.
