Register award announced for business concern (10)
I believe the answer is:
enterprise
'business concern' is the definition.
(I've seen this before)
'register award announced' is the wordplay.
'register' becomes 'enter' (entering is a kind of registering).
'award' becomes 'prize' (synonyms).
'announced' indicates a 'sounds like' (homophone) clue.
'prize' sounds like 'prise'.
'enter'+'prise'='ENTERPRISE'
'for' is the link.
(Other definitions for enterprise that I've seen before include "business concern" , "Project, undertaking" , "Get-up-and-go - venture" , "Data may be on-board here" , "audacity" .)
