Do UTM URL parameters hurt SEO backlink value?

Does www.example.com and www.example.com/?utm_source=Google&utm_medium=Press+Release&utm_campaign=Google have the same SEO backlink value? I would assume that Google knows the difference.

Google knows the difference and that is why they wouldn't give it the same value.

They are looking for other websites to link to your site on their own. No organic link is going to have tracking variables appended to it, meaning that the backlink was "self-generated". As such, your link value is discounted (especially press release links).
