Over the past several earnings seasons, Facebook’s story has been its Teflon-like ability to shrug off controversy. The company kept growing, and posting record revenues, even as it was lambasted over foreign interference in elections, spreading misinformation and harmful content, and compromising its users’ privacy. This quarter, that Teflon has cracked.

Facebook narrowly missed analyst expectations on its second-quarter earnings Wednesday. Although company execs have been warning about a slowdown for months, the miss still sent Facebook’s stock price into a historic tumble. Investors are worried because Facebook says growth will keep slowing, and margins will diminish as it addresses privacy challenges.
