EPS
Earnings Per Share (EPS) is the portion of a company's net profit allocated to each outstanding equity share, and serves as one of the most fundamental indicators of corporate profitability.
EPS is calculated by dividing a company's net profit (after tax and preference dividends) by the weighted average number of equity shares outstanding during the period. It translates the absolute profit number into a per-share figure, making it comparable across companies of different sizes and facilitating the computation of the P/E ratio.
In the Indian context, EPS is reported quarterly and annually under Ind AS. NSE and BSE mandate that listed companies publish their quarterly earnings within 45 days of the quarter end (60 days for the annual results). The EPS figure in these filings is the key number analysts and media track during results season — a beat or miss relative to analyst consensus estimates can move a stock sharply in either direction.
Reliance Industries' EPS trajectory illustrates how corporate transformation gets captured in this metric. As Reliance pivoted from a predominantly petrochemicals and refining business to one that included Jio (telecom) and Reliance Retail, its consolidated EPS grew substantially over the late 2010s and early 2020s. Investors who tracked this EPS growth story were rewarded with significant stock price appreciation over that decade.
A key nuance often missed by retail investors is the difference between basic EPS and diluted EPS. Basic EPS uses only existing shares, while diluted EPS factors in the potential dilution from employee stock options (ESOPs), convertible bonds, or warrants. For companies with large ESOP programmes — common in Indian IT and new-age companies — the diluted EPS can be meaningfully lower than basic EPS, and the latter is the more conservative measure to use.
Negative EPS (a loss per share) is not necessarily permanent and should be contextualised. Startups or companies undergoing heavy capital expenditure phases may report losses for several years before turning profitable. However, persistent negative EPS alongside deteriorating cash flows in a mature business is a red flag worth investigating through the full financial statements.
