Apparently, Yedioth Ahronoth and Hamad Books created in partnership, Intelligence - Publishing House which is also know as Yedioth Sfarim (Yedioth Books).
Back cover of PS has "Yediothsfarim" (Yedioth Books) in a url (no longer functional).
Copyright page has "Books in the Attic" and "Intelligence - Publishing House" founded by "Yedioth Ahronoth" and "Hamad Books".
PS ISBNs appear to have been reused: 978-965-448-765-8 was also used for COS and HBP and 978-965-511-028-9 was reused for GOF; see Potterglot article.

Publishing relationships here are complicated. Books in the Attic published the books in collaboration with Yedioth Books, also known as "Intelligence Publishing House" which in turn was a collaboration between "Hamad Books" and "Yedioth Ahronoth". All of these appear somewhere on the book.
