You've specified /regex. The character "." is a special character in a regex
which matches anything. So ".out" will match "mout".

You can remove the special nature of "." by preceding it with a backslash. You
should probably also tie the match to the end of the string by appending a
dollar:
print,strsplit(str9,'\.out$',/extract,/regex).

A better approach might be to use the function file_basename:

print,file_basename(str9,[".out"])
