sed kan remember a matching string (a number of characters different from a space) and show it like this:

mystring='localhost -> ABC-NPCCache-Resource-Provisioning 2.3.1.1 '
echo "${mystring}" | sed -r 's/.*-> ([^ ]*) ([^ ]*).*/\1.\2.tar.gz/'
# result:
ABC-NPCCache-Resource-Provisioning.2.3.1.1.gz

this sed one-liner may give you a hand:

sed 's/.*-> //;s/ /-/;s/$/.tar.gz/'

with your example:

kent$  sed 's/.*-> //;s/ /-/;s/$/.tar.gz/'<<<'localhost -> ABC-NPCCache-Resource-Provisioning 2.3.1.1'    
ABC-NPCCache-Resource-Provisioning-2.3.1.1.tar.gz

or with awk:

awk -F' -> ' '{gsub(/ /,"-",$2);$0=$2".tar.gz"}7'
