Check out the companies making headlines in midday trading.

Snap — Shares of the Snapchat parent company cratered 28.1% after it missed revenue estimates and saw its slowest sales growth since going public as advertising spending slows. The results from Snap hit other ad-reliant stocks, sending shares of Pinterest and Meta Platforms down about 6.4% and 1.2%, respectively.

Twitter — The social media stock sank more than 4.9% Friday amid a slew of media reports on Twitter and Elon Musk. The Washington Post reported on Thursday that the Tesla CEO told some potential investors that he would slash nearly three-quarters of Twitter’s workforce in his deal to buy the company. Bloomberg reported that the Biden administration is weighing whether it should subject some of Musk’s ventures to national security reviews.

American Express – Shares of American Express fell about 1.7% even after the bank reported quarterly earnings and revenue that beat analysts’ expectations. The bank also raised its full-year forecast and increased the amount of money it set aside for potential defaults. That signals higher interest rates could hurt customers in the future.

Verizon — Shares of the telecom giant slid 4.5%. Though the company beat consensus estimates for earnings per share and revenue in the third quarter, it reported smaller growth in postpaid net phone lines than expected, citing impacts from price increases.
