This text is almost unreadable to me. The characters are actually touching one another, blending together.

It looks like a font substitution issue. You don’t have the type face installed that was originally used to create this PDF. And the font was not embedded in the PDF. So whatever you’re using to view, the PDF is utilizing something like Aerial or Helvetica as a stand in sans serif type face but retaining the kerning/layout used for the original font.
