Website aggregator that provides announcement and supplementary data presentations for quarterly results?

I am Theodore of Singapore and we have sginvestors.io and dividends.sg that let us search for stocks and go to their announcements to quickly view announcement and result presentations.

Are there any similar websites for US stocks instead of manually going to each of the website's investor relations? I am looking for supplementary data slides in particular.
