Check out the companies making headlines before the bell. Disney â Shares were down about 1% after the media giant reported quarterly results that beat analyst expectations, thanks in part to strong performance at its streaming unit.

Airbnb â Weaker-than-expected revenue guidance for the third quarter hurt Airbnb shares in the premarket, losing nearly 14%. The company sees revenue in a range of $3.67 billion to $3.73 billion. Analysts expected a forecast of $3.84 billion. Reddit â The social news company added 1%% in premarket trading.
