[stunnel-users] Can parent proxy see what's going through stunnel

Hi community, I'm using stunnel behind my company proxy like this:

protocol=connect connect=proxy.ourcompany.com:3128 protocolHost=myownproxy.net:443

Since I notice that our company seems to be intercepting HTTPS because my web browser sometimes sees our company's certificate instead of the real websites'. So I want to make sure if the company proxy can see what's going through stunnel. Thanks in advance.
