Key Takeaways
- EPS growth can reflect a company's capital allocation choices rather than improvements in its competitive position.
- A temporary improvement in reported earnings may disappear when unusual gains or favourable tax conditions reverse.
- The market's valuation of EPS growth depends partly on whether investors believe that growth can continue.
Why Can EPS Increase Without Business Growth?
A company reports 12% EPS growth, yet revenue is barely higher and operating profit is flat. At first glance, the results look encouraging. However, the explanation may have more to do with financial calculations than business performance.
Earnings per share (EPS) measures the profit attributable to ordinary shareholders for each share. It is generally calculated by dividing earnings available to ordinary shareholders by the weighted-average shares outstanding during the reporting period. This means EPS can improve through changes in either earnings or the number of shares.
How Share Buybacks Change the Calculation
Repurchasing shares reduces the number of shares included in the EPS calculation, so the same profit is divided among fewer shares. Consider a hypothetical company earning $100 million with 20 million weighted-average shares. Its EPS is $5.
If repurchases lower the weighted-average count to 18 million, EPS rises to approximately $5.56. That is an 11.1% increase with no additional profit. Because EPS uses a weighted average, a mid-year buyback only partly lowers the share count in that year. The full effect appears in the following year.
Buybacks are not automatically harmful. Their value depends on the purchase price, the funding method and alternative uses of the company's cash. A buyback funded by debt, for example, can add interest expense, which offsets part of the EPS benefit.
Other Reasons Reported EPS Can Improve
Share repurchases are not the only explanation. A lower effective tax rate can increase net income even when operating performance remains stable. Reduced interest expense can have a similar effect if a company repays debt or refinances borrowing at a lower cost.
One-time gains, such as profits from selling an asset, can also lift reported earnings. These gains may improve a reporting period without creating a recurring source of income.
Why Diluted EPS Deserves Attention
Employee stock options, restricted stock units and convertible securities can increase the potential number of shares. Basic EPS uses the weighted-average ordinary shares outstanding, while diluted EPS also reflects potential shares that would dilute EPS.
A company may report improving basic EPS while dilution limits the benefit available to existing shareholders. The IFRS Foundation's IAS 33 standard explains the requirements for calculating and presenting both measures. US-listed companies follow ASC 260 under US GAAP, which has similar requirements.
TwikUp's Perspective: Examine the Source of Growth
Investors should compare EPS with revenue, operating income, net income and operating cash flow across several reporting periods. Then read the EPS reconciliation in the financial statement notes. That reconciliation shows whether the change came from earnings or from the share count, rather than leaving you to rely on the headline figure.
