Approach 1: Westpac Banking Excess Returns Analysis

The Excess Returns model looks at how much profit a bank can earn above its cost of equity, then capitalises those extra earnings to estimate what the shares might be worth today.

For Westpac, the model uses a Book Value of A$21.31 per share and a Stable EPS of A$2.24 per share, based on weighted future Return on Equity estimates from 13 analysts. The Average Return on Equity used in the model is 10.08%, while the Cost of Equity is A$1.75 per share.

The difference between what Westpac is expected to earn and its equity cost is the Excess Return, which is A$0.50 per share. That stream of excess earnings is applied to a Stable Book Value of A$22.25 per share, sourced from weighted future Book Value estimates from 10 analysts, to arrive at an estimated intrinsic value.

On this Excess Returns basis, the model suggests Westpac shares trade at a 21.9% premium to intrinsic value. This implies the stock screens as overvalued at the recent A$41.00 share price.

Approach 2: Westpac Banking Price vs Earnings

For a profitable bank like Westpac, the P/E ratio is a useful yardstick because it links what you pay per share to the earnings the business is already generating. It is a quick way to see how much the market is willing to pay for each dollar of profit.

Story Continues

What counts as a "normal" P/E depends on how investors see a company’s growth prospects and risk. Higher expected growth or lower perceived risk can support a higher multiple, while slower expected growth or higher perceived risk usually points to a lower one.

Westpac currently trades on a P/E of 20.26x. That sits above the Banks industry average of 10.87x and also above the peer average of 19.31x. Simply Wall St’s Fair Ratio for Westpac is 20.95x, which is a proprietary estimate of what the P/E could be given factors such as its earnings profile, industry, profit margins, size and company specific risks. This Fair Ratio can be more informative than a simple comparison with peers or the broad industry because it adjusts for these company specific characteristics.

With Westpac’s actual P/E of 20.26x sitting slightly below the Fair Ratio of 20.95x, the valuation on this metric looks about right.

Upgrade Your Decision Making: Choose your Westpac Banking Narrative

Earlier we mentioned that there is an even better way to understand valuation. Let us introduce you to Narratives, which are simply the stories you and other investors tell about Westpac Banking, backed by your own assumptions for fair value, future revenue, earnings and margins, and then linked to a clear financial forecast and fair value that you can compare with today’s share price.

On Simply Wall St’s Community page, Narratives are easy to use because you can see different views on Westpac Banking in one place. For example, one investor might think the fair value is around A$27.50 based on more cautious earnings expectations, while another might see it closer to A$38.00 with a more optimistic outlook. You can then compare each Fair Value to the live price to help decide whether the shares look attractive or expensive relative to that story.

As new information comes in, such as Westpac’s latest earnings, updates to its A$35.31 fair value estimate or news like the recent shareholder approval to amend its constitution, these Narratives refresh automatically. This helps keep your decision making tied to both the numbers and the evolving story behind them.
