How Do You Calculate Ameren's P/E Ratio?

The formula for price to earnings is:

Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)

Or for Ameren:

P/E of 22.01 = $74.190 ÷ $3.371 (Based on the trailing twelve months to December 2019.)

(Note: the above calculation results may not be precise due to rounding.)

Is A High P/E Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each $1 the company has earned over the last year. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

Does Ameren Have A Relatively High Or Low P/E For Its Industry?

The P/E ratio essentially measures market expectations of a company. The image below shows that Ameren has a higher P/E than the average (19.0) P/E for companies in the integrated utilities industry.

That means that the market expects Ameren will outperform other companies in its industry. Shareholders are clearly optimistic, but the future is always uncertain. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

How Growth Rates Impact P/E Ratios

Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. That means unless the share price increases, the P/E will reduce in a few years. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

Ameren's earnings per share were pretty steady over the last year. But it has grown its earnings per share by 6.9% per year over the last five years.

A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

The 'Price' in P/E reflects the market capitalization of the company. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

So What Does Ameren's Balance Sheet Tell Us?

Ameren's net debt is 53% of its market cap. This is enough debt that you'd have to make some adjustments before using the P/E ratio to compare it to a company with net cash.

The Bottom Line On Ameren's P/E Ratio

Ameren has a P/E of 22.0. That's higher than the average in its market, which is 13.3. With relatively high debt, and reasonably modest earnings per share growth over twelve months, it's safe to say the market believes the company will improve its growth in the future.
