Morphology

underperform = perform (transparent) = under + perform

The productive prefix 'under-' meaning 'insufficiently' or 'less than' combines directly with 'perform', so the sense 'perform less well' is inferable from the components.

Etymology

Underperform is built from the parts under- 'below' and perform 'to carry out' or 'to do well'. So to underperform is to do 'below' the level people expect — to do worse than required.
