Pinterest shares fell 22 percent after weak fourth-quarter results and a tariff shock, CNBC reported on Feb. 13.

Pinterest's fourth-quarter revenue was $1.32 billion, missing analyst estimates. Net profit fell 85 percent from a year earlier to $277 million.

Adjusted EBITDA, a key metric, was $541.5 million, below the expected $550 million. Pinterest forecast first-quarter revenue of $951 million to $971 million, below market expectations. CEO Bill Ready (빌 레디) said external shocks related to tariffs and lower advertising spending by large retailers weighed on results.

Pinterest plans to cut 15 percent of its workforce and shrink office space to boost AI investment. Citi lowered its rating on Pinterest to neutral from buy, saying short-term pressure on profitability would persist due to tariffs and weaker advertising from certain industries. Goldman Sachs said there were short-term headwinds from tariffs and lower consumer spending, but advertiser diversification and an automation strategy were key to long-term growth.

Pinterest's global monthly active users in the fourth quarter rose 12 percent from a year earlier to a record 619 million, with growth among Generation Z users particularly notable.
