Basic vs diluted
Diluted EPS includes options and convertibles, always the more conservative, truer figure. Use it.
Definition
What is EPS (earnings per share)?
Earnings per share (EPS) is a company's net income, minus any preferred dividends, divided by its shares outstanding. It expresses total profit on a per-share basis: the figure the P/E ratio is built on and the number companies are judged against every quarter. Diluted EPS uses a fully-diluted share count that includes options and convertibles.

Short answer
EPS is profit sliced per share - but it's easy to flatter. Buybacks shrink the share count and lift EPS even if total profit is flat, and one-off items distort it. Read EPS growth alongside revenue and free cash flow to know whether it's real.
Reading EPS well
GAAP vs adjusted
'Adjusted' EPS strips out items management chooses to exclude. Compare it to GAAP to see exactly what was removed.
The buyback effect
Fewer shares lift EPS even with flat profit. Check whether growth is operational or just financial engineering.
Trailing vs forward
Trailing EPS uses the last 12 months; forward uses estimates. The P/E ratio follows whichever you choose.
Why EPS growth can be an illusion
A company earns $2B of net income with 1B shares outstanding: EPS is $2.00. If it buys back 100M shares, EPS rises to about $2.22 on exactly the same profit: an 11 percent 'increase' with zero growth in the underlying business.
Buybacks can be a perfectly good use of capital, but they make EPS a noisy growth signal. That's why investors separate EPS growth driven by rising profit from EPS growth driven by a shrinking share count, and cross-check against free cash flow, which buybacks don't inflate.
