Earnings Per Share (EPS)

Imagine two companies each earn $10 million in profit this year.

Company A has 1 million shares outstanding.

Company B has 10 million shares outstanding.

Even though both companies earned the same amount, Company A generated more profit per share.

Company A: $10 EPS

Company B: $1 EPS

That’s what Earnings Per Share (EPS) measures:

How much profit a company earns for each share of stock.

Investors often use EPS to help compare companies, track profitability over time, and evaluate whether a stock may be worth further research.

EPS Formula

EPS is calculated by taking a company’s net income and dividing it by the number of shares it has outstanding. In other words, it shows how much profit belongs to each share of stock.

Most companies report two versions of EPS: Basic EPS and Diluted EPS. They’re similar, but there’s one important difference investors should understand.

Basic EPS

Basic EPS looks at the shares a company currently has outstanding today.

EPS = (Net Profit– Preferred Dividends) / End-of-Period Common Shares Outstanding.

A company’s net profit is what’s left after expenses are deducted from revenue. Preferred dividends are also subtracted because those payments must be made before common shareholders receive anything.

Diluted EPS

Diluted EPS looks ahead and asks: “What would happen if the company had to issue more shares in the future?”

This can happen when companies offer employee stock options or issue convertible debt that can later turn into shares.

If more shares are added, the company’s profits would be spread across a larger number of shares, which lowers the EPS.

Diluted EPS = (Net Profit – Preferred Dividends) / End-of-Period Common Shares Outstanding + Diluted Shares.

Because diluted EPS includes potential future shares, it’s usually lower than basic EPS.

Many investors consider diluted EPS a more conservative measure because it reflects the impact of potential future share issuance.

Difference in Calculation Method

The main difference between basic EPS and diluted EPS comes down to the number of shares being counted.

Basic EPS only looks at the shares currently available today.

Diluted EPS also includes shares that could potentially be added in the future through things like employee stock options or convertible debt.

That’s important because if more shares are created later on, a company’s earnings would be spread across more shareholders, lowering the profit tied to each individual share.

Examples

Let’s say Company ABC earned $12 million in profit last year, paid $2 million in preferred dividends, and currently has 5 million shares outstanding.

Its basic EPS would look like this:

($12,000,000 - $2,000,000) / 5,000,000 = $2 per share

That means Company ABC earned $2 per share.

Now let’s imagine the company also has employee stock options and convertible debt that could add another 2 million shares in the future.

Its diluted EPS would look like this: 

($12,000,000 - $2,000,000) / (5,000,000 + 1,000,000 + 1,000,000) = $1.43 per share

In this example, diluted EPS drops to $1.43 per share because the company’s earnings are being divided across more potential shares.

That’s why diluted EPS is often considered the more conservative and realistic measure of a company’s earnings per share.

A rising EPS doesn’t always mean a company is becoming stronger.

One-time gains or losses can sometimes affect EPS, making results appear stronger or weaker than underlying business performance.

Sometimes EPS increases because a company is buying back shares, reducing the number of shares outstanding rather than increasing profits. EPS can also be affected by accounting changes, stock splits, or one-time events.

That’s why investors often look at EPS alongside other metrics like revenue growth, cash flow, and a company’s price-to-earnings (P/E) ratio before making investment decisions.

There’s no universal number that makes an EPS “good” or “bad.”

What matters more is how a company’s EPS changes over time and how it compares to similar companies in the same industry.

For example, steady year-over-year EPS growth can be a sign that a company is growing profits and improving financially. On the other hand, a declining EPS may suggest the company is facing challenges.

It’s also important to understand that stock prices don’t move based only on whether EPS goes up or down. Investor expectations matter too.

A company’s stock price can fall even if EPS increases, if investors expected even stronger results. The opposite can also happen. A stock price may rise despite falling EPS if the results were better than investors feared.

That’s why EPS is best used as one piece of the puzzle, alongside other factors like revenue growth, cash flow, debt levels, and valuation metrics like the price-to-earnings (P/E) ratio.

While EPS is a commonly accepted metric, no metric is perfect. Limitations of EPS include:

What is a good EPS and P/E Ratio?

There’s no definition of a “good” or “bad” EPS value. Generally, with all else being equal, investors may view higher EPS favourably, but EPS should be evaluated alongside factors such as revenue growth, debt levels, cash flow, and industry conditions.

The opposite is true for a company’s price-to-earnings (P/E) ratio. In most cases, the lower a company’s P/E ratio is, the better. A lower P/E ratio may suggest a stock is relatively inexpensive compared to earnings, but investors should consider growth prospects, industry average, peer comparison and other valuation measures

What does a higher EPS mean?

Companies with strong earnings may have greater capacity to pay or issue dividends to it's shareholders, although dividend decisions depend on various other factors. It’s also seen as an indication that the company is performing well. Stocks with a higher EPS may be more attractive to other investors than stocks with a lower EPS.

What should I know about EPS?

EPS is used to determine how much money a company makes for each share of its stock and is often used as an indicator of a company’s potential profitability. Typically, the higher the EPS, the more profitable a company is seen to be. That said, a lot of things can affect a company’s EPS. While EPS can be a good indicator that a company is profitable, it’s only one indicator and should be considered in combination with other metrics like share price and the company’s price-to-earnings ratio.

What does negative EPS mean?

A negative EPS is a sign that a company is spending more than its revenue and losing money.

What does it mean if EPS decreases?

A decreasing EPS can indicate a decline in the company’s profits. It may also be a sign that the company will be less likely to pay dividends to shareholders in the future. 

Why is EPS important to investors?

Investors use EPS to determine how profitable investing in a company’s stock may be. While nothing is ever guaranteed, the higher a company’s EPS is, the more likely it is that the company will be profitable and be able to pay dividends to their shareholders. 

Earnings Per Share (EPS) measures how much profit a company earns for each share of stock it has outstanding. Investors often use EPS to evaluate a company’s profitability, compare companies within the same industry, and track financial performance over time. While a higher EPS can be a sign of stronger earnings, EPS works best when used alongside other financial metrics like revenue growth, cash flow, and a company’s price-to-earnings (P/E) ratio.
