Well, it depends on whether the CA uses intermediate certs (and keys),
and if so, whether the server operators decide to (pre)configure them.
According to X.509 principles, it is sufficient to have the root(s);
SSL, and openssl library, supports sending the chain if/as needed.
But as I noted s_client apparently doesn't; remember that most of
the command-line 'apps' are intended to be basic tools to do things
that you don't have a more complete, specific application for.

You might also look at the .pfx data they gave you. IF the people
who created it coordinated with (or are the same as!) the people
who control the server, it would have been logical for them to include
in the 'bag' any/all intermediate cert(s) needed to use your cert.
Unless you converted foryou.pfx to your.pem with -clcerts (or edited it),
you should be able to look through your.pem and see if there's
a certificate block preceded by a subject=imedCAname which
matches (exactly) issuer= for the cert with subject=yourname.
