(Reuters) -Shares of Snap Inc plummeted 25% on Thursday after the owner of photo messaging app Snapchat said privacy changes implemented by Apple Inc on iOS devices hurt the company's ability to target and measure its digital advertising.

The Santa Monica, California-based company, which earns the vast majority of its revenue from selling digital advertising on the app, said the issue was compounded by global supply chain disruptions and labor shortages and caused brands to pull back on their advertising spending.
