Shares Outstanding Annual
Weighted average diluted, as the filer reports it for each period. An average cannot be added across periods, so this one is always shown per period the filer tagged rather than as a trailing year.

EPS Annual
The filer's own published earnings a share for each quarter, four quarters added up. The company page divides trailing net income by the share count instead, which lands within about 1% of this and is not the same sum, so the two are named differently rather than presented as one figure.
