Things are going from bad to worse for Yahoo.

Of course, you’ll remember Verizon signed a $4.83 billion deal to buy Yahoo before Yahoo discovered a half-billion emails had been hacked back in 2014. Today, Verizon general counsel Craig Silliman said the company has “reasonable basis” to believe the breach is enough to let Verizon back out of the deal.

The company, according to Silliman, is “looking to Yahoo to demonstrate the full impact” of the breach, according to a report from ABC News.

Serious question: What happens to Yahoo if that happens?
