Your anchors (^) are messed up, they mean the beginning of the string when on the left-most position. Also, you need to do the actual splitting, after you do the extraction. 
# If you just want the stuff in between
$transcript =~ /CORPORATE PARTICIPANTS(.*)CONFERENCE CALL PARTICIPANTS
+/i;
$1;

# $transcript =~ /CORPORATE PARTICIPANTS foo bar baz CONFERENCE CALL P
+ARTICIPANTS/i;
# If you want foo, bar, baz
my @words = split /\W/, $1;
say for @words;
