Approach 1: Westpac Banking Excess Returns Analysis

The Excess Returns model looks at how much profit a company is expected to earn above the return that equity investors require, and then values those extra profits over time.

For Westpac Banking, the starting point is its balance sheet strength and profitability. The model uses a Book Value of A$21.31 per share and a Stable Book Value estimate of A$22.32 per share, based on weighted future book value estimates from 10 analysts. Earnings are captured through a Stable EPS of A$2.26 per share, sourced from weighted future return on equity estimates from 13 analysts.

The required return for shareholders is reflected in a Cost of Equity of A$1.74 per share. Against this, the model estimates an Excess Return of A$0.52 per share, with an Average Return on Equity of 10.12%. These inputs together produce an intrinsic value of A$34.45 per share under the Excess Returns framework.

Compared to the recent share price of A$40.69, this Excess Returns estimate suggests the stock is around 18.1% overvalued on this measure.

Approach 2: Westpac Banking Price vs Earnings

The P/E ratio tends to work well for profitable companies because it links what you pay per share directly to the earnings that support that share price. For banks, where earnings are a key focus, P/E is often a primary reference point for investors.

What counts as a “normal” P/E depends on how the market views a company’s growth prospects and risk. Higher expected growth or lower perceived risk can justify a higher P/E, while slower growth or higher risk usually points to a lower multiple.

Westpac Banking currently trades on a P/E of 20.11x, compared with an industry average for Banks of 11.31x and a peer average of 19.52x. Simply Wall St’s Fair Ratio for Westpac Banking is 22.72x, which is its proprietary estimate of what a justified P/E could be given factors such as earnings growth characteristics, industry, profit margins, market cap and risk profile.

The Fair Ratio can be more useful than a simple peer or industry comparison because it adjusts for those company specific traits rather than assuming all banks deserve the same multiple. Since the current P/E of 20.11x is below the Fair Ratio of 22.72x, this framework points to Westpac Banking trading at a lower multiple than those inputs would suggest.
