Diluted EPS Formula and Calculation

Earnings Per Share after adjusting the number of shares outstanding for dilutive securities

What is the diluted EPS formula?

The Diluted EPS formula is equal to Net Income less preferred dividends, divided by the total diluted number of shares outstanding (basic shares outstanding plus the exercise of in-the-money options, warrants, and other dilutive securities).

Diluted EPS Formula:

Diluted EPS = (net income – preferred dividends)  /  (weighted average number of shares outstanding + the conversion of any in-the-money options, warrants, and other dilutive securities)

 

Diluted EPS example calculation

Below is a simple example of how to calculate diluted EPS for a company without any preferred shares.

As you will notice in the analysis that was performed, the number of diluted shares outstanding was derived by adding up the number of in-the-money options and assuming they were added to the basic number of shares outstanding in the period.

By doing a full analysis (as shown) we see that in 2017 Basic EPS is $2.45, Diluted EPS is $2.20, and Fully Diluted EPS is $1.96.

The diluted EPS figure of $2.20 paints the most accurate picture for an investor, while the fully diluted EPS figure of $1.96 presents the most conservative (or worst case) scenario.

 

Why do investors and analysts calculate diluted EPS?

The reason that analysts and investors calculate diluted EPS is that basic EPS may overstate the actual amount of earnings per share that a common shareholder is entitled to.

Companies frequently have dilutive securities outstanding like options and warrants that will increase the total number of shares outstanding when converted.

Since the conversion of option into shares won’t add any additional net income to the business, the increased share count makes the conversion dilutive.

Options may have been granted to employees, for example, that are in-the-money (strike price is below the current market price) but have not been converted yet.  If options are in-the-money, they should be accounted for in a diluted EPS calculation.

Breaking down the numerator – net income and preferred dividends

The numerator of the EPS formula is Net IncomePreferred Dividends.  Preferred dividends need to be deducted from net income, since that portion of earnings will not be available to common shareholders, and we are calculating the Earnings Per Share (EPS) for common shareholders.

The standard calculation for Earnings Per Share is net income divided by shares outstanding.  In the case of a company that pays a preferred divided, the EPS for common shareholders is Net Income less Preferred Dividends (since those get paid out first) divided by shares outstanding.

Breaking down the denominator #1 – shares outstanding

The denominator of the EPS formula is Weighted Average Basic Shares Outstanding + Options + Warrants + Other dilutive securities that are in-the-money.

The weighted average basic shares outstanding is the average number of shares that were outstanding over the time period.  If for example, the time period was one year and no shares were issued or repurchased during the year, then the beginning number of shares, ending number of shares, and weighted average number of shares are all equal to each other.

 

Breaking down the denominator #2  – adjustments to shares outstanding

By looking at the notes in a company’s financial statements, you will find a schedule with a list all the issued options and warrants, along with their strike or conversion prices and maturity dates.

This is where most of the effort is required.  A good financial analyst will recreate a table in Excel with all the details, then compare the strike/conversion prices to the current share price (or average share price over the period) and determine which securities are in-the-money.

The next step is to assume those securities are converted, the company receives the cash, and the number of shares outstanding goes up.

 

Should you use fully diluted shares outstanding?

It should be noted that you can take the fully diluted number of shares outstanding as the denominator if you want to be the most conservative.  It could be overly conservative though, as some of the options may be far out-of-the-money and never convert into shares.  For this reason, it’s better to do take the steps
