The Ghost in the EPS: Why Rising Earnings Can Hide a Flat Business

Imagine you own a small neighborhood sweet shop. Every year, you make and sell exactly 10,000 boxes of laddoos. Your total profit is completely constant, but one day you decide to buy back half the ownership stakes from your silent partners. Suddenly, your personal share of the earnings doubles. You might feel wealthier, but has your sweet shop actually grown? Not by a single laddoo.

This is the core paradox of Earnings Per Share (EPS). As retail investors, we are often trained to look at EPS growth as the ultimate proof of a company's success. If EPS is going up, the business must be thriving. But this is not always true. EPS is simply a fraction: net profit divided by the number of shares. You can increase the value of this fraction in two ways: by making the top number (profits) bigger, or by making the bottom number (share count) smaller.

The Share Buyback Illusion

When a company has excess cash, it can choose to buy back its own shares from the open market and extinguish them. This reduces the total number of outstanding shares. Even if the actual business profits do not grow by a single rupee, the remaining shareholders see their EPS rise. While buybacks can be a healthy way to return capital to shareholders, they can easily mask a stagnant business.

One-Off Gains and Margin Cycles

Share buybacks are not the only way EPS can paint a misleading picture. Two other common culprits are one-off gains and temporary margin cycles. A company might sell a piece of surplus land or a factory. This injects a massive, one-time cash inflow into the net profit. For that specific year, the EPS will shoot through the roof. But this is a non-recurring event. You cannot sell the same land twice to keep earnings growing.

Similarly, a business can experience a temporary boost in profitability due to commodity price cycles. For instance, a paint maker might benefit from a sudden, sharp drop in global crude oil prices (its key raw material). Even if the company does not sell any more cans of paint, its production costs plummet, causing profits—and EPS—to surge. However, as soon as oil prices recover, those margins shrink, and the EPS collapses back to reality.

How to Protect Your Portfolio

To avoid falling into these EPS traps, you must always look at EPS growth in tandem with revenue (or sales) growth. True, sustainable business growth is almost always driven by top-line revenue expansion. If a company is selling more products, capturing more market share, or entering new territories, its revenue will climb. When revenue and EPS grow together, you are looking at a healthy, expanding business. If EPS is climbing while revenue is flat or falling, the growth is likely an optical illusion.
