Cristiano's signed a mega contract with Al Nassr he's staying for 2 years. I don't know they've given him shares in the company he would've stayed because other teams can't give him mega contracts. If Al Nassr don't win their SPL it won't be considered successful signing.
Ronaldo is already 40 years old, and what makes me curious is whether Ronaldo can maintain his performance for the next two seasons, so that he can complete the contract that was just signed. Regardless of the details of the deal which are quite luxurious, I think Ronaldo deserves it. Looking back a little, Al Nassr goal in bringing Ronaldo was not only to win trophies, but to increase the popularity of the Saudi Pro League. However, until now Al Nassr has not succeeded in winning the main trophy, but this failure is not a big problem, because the Saudi Pro League is more advanced than before with the presence of Ronaldo.
