EPS
Earnings per share.
EPS (earnings per share) is net income divided by the number of shares outstanding. It's one of the most watched numbers in finance: it appears in every earnings report, it's the denominator of the P/E ratio, and its surprise versus consensus moves prices in the hours after results.
Two versions exist: basic EPS, which uses shares actually outstanding, and diluted EPS, which also accounts for shares that could potentially be issued (stock options, warrants, convertible bonds). Diluted EPS is more conservative and is the figure analysts use for comparisons.
Worked example
Microsoft's fiscal year ending June 2025 saw net income of about $108 billion against roughly 7.4 billion shares outstanding. EPS = 108,000 ÷ 7,400 = $14.59 per share.
For a single quarter, Q3 FY2026 (calendar Q1 2026), Microsoft reported EPS of $3.46 versus consensus of $3.22 — a 7% beat. Beats of that size historically move the stock 3–6% in the next 24 hours, though a single print never guarantees future price.
When it's used
EPS does three things primarily. First, it lets you compute the P/E ratio (P/E = price ÷ EPS). Second, it compares per-share profitability across companies in the same sector (higher EPS usually means more mature or more efficient). Third, EPS growth year over year is one of the cleanest indicators of underlying business health.
Limits
EPS can be engineered through buybacks: shrinking the denominator without growing earnings mechanically lifts EPS, but the business isn't stronger. Accounting EPS also includes non-cash items (depreciation, one-off writedowns) that can distort it. Serious analysts therefore watch adjusted EPS and free cash flow per share alongside the headline number.
Frequently asked
What's the difference between EPS and net income?
Net income is the company's total bottom line. EPS divides that by share count so it can be compared apples-to-apples with the share price.
What does 'EPS beat' mean?
It means reported EPS came in higher than the average analyst estimate (consensus). A 'miss' is the opposite. Beats and misses often move the stock in the hours right after earnings are released.
Is rising EPS always a good sign?
Not automatically. Quality matters: EPS rising on buybacks is weaker than EPS rising on revenue and margin growth. Organic revenue growth paired with EPS growth is the cleanest signal.
