A Look At The Impact Of National Grid's Dilution On Its Earnings Per Share (EPS)

National Grid has improved its profit over the last three years, with an annualized gain of 30% in that time. In contrast, earnings per share were actually down by 1.0% per year, in the exact same period. And at a glance the 28% gain in profit over the last year impresses. On the other hand, earnings per share are pretty much flat, over the last twelve months. Therefore, one can observe that the dilution is having a fairly profound effect on shareholder returns.

Changes in the share price do tend to reflect changes in earnings per share, in the long run. So it will certainly be a positive for shareholders if National Grid can grow EPS persistently. However, if its profit increases while its earnings per share stay flat (or even fall) then shareholders might not see much benefit. For the ordinary retail shareholder, EPS is a great measure to check your hypothetical "share" of the company's profit.
