From Investopedia:
Many companies issue disclaimers when they issue forward-looking statements. Despite an implicit understanding that certain statements are largely speculative in nature, the U.S. Securities and Exchange Commission (SEC) mandates public companies include this disclaimer on all published management materials geared toward investors. This requirement emphasizes that stockholders generally may not take legal action against company management for forward-looking statements that prove to be inaccurate.
From my understanding, they can say whatever they want in the forward guidance since they are legally protected anyway?
