Mizuho (TSE:8411) Stock May Be 39% Undervalued On Equity Returns

Mizuho Financial Group has turned into a powerful long term winner for shareholders, and the question now is whether a stock that has run this far is properly explained by the returns it earns on its capital. With the share price at ¥8,566 at the last close, investors are asking what kind of capital efficiency sits behind that move.

• Over the past 5 years, the stock has delivered a very large gain of about 7x, which puts real pressure on the idea that the underlying returns on capital are doing the heavy lifting.
• The bank’s model, which relies on how well it converts its balance sheet into interest income and fee revenue, can shape expectations for the durability of its returns on equity and the reinvestment opportunities that support those returns.

Does Mizuho Financial Group Look Undervalued on Excess Returns?

The Excess Returns model evaluates how much value Mizuho Financial Group creates above the cost of its equity capital. It uses accounting measures like book value and earnings rather than projecting cash flows year by year.

For Mizuho Financial Group, the inputs suggest the bank is expected to earn more on its equity base than investors require. Book value is ¥4,730.66 per share, with an estimated stable EPS of ¥741.80 per share against a cost of equity of ¥333.37 per share. That gap produces an excess return of ¥408.43 per share, built on an average return on equity of 13.05% and a projected stable book value of ¥5,683.99 per share. Within this framework, the Excess Returns projections put Mizuho Financial Group's estimated intrinsic value substantially above the current share price of ¥8,566.00. This suggests the market is not fully pricing in those expected returns on capital. Find out what Mizuho Financial Group could be worth using our Excess Returns estimate.
