For background, read this. A snippet:

Local media would be and no doubt are expected to seize upon such a report as if it were hard economic fact, and one would be hard-pressed to imagine any “financial impact” figure that would strike them as too large to be believable. HB2 will cost the state millions? Tens of millions? Hundreds of millions? Something in the billions?

Today provides some clarity on that question. Media economists think this expected and enormous negative economic impact will take a little time.

That is, we can’t expect keeping the status quo ante regarding whether males can walk unquestioned into women’s showers, changing rooms, and bathrooms will cost the state hundreds upon hundreds of millions of dollars overnight.

The News & Observer reports on a “Politifact” examination, as far as it goes, of appointed Rep. Chris Sgro’s assertion that HB2 has already cost the state $500 million. The N&O’s “Fact Check” ruling, however, says let’s not be too hasty:

It’s true that the state might eventually lose up to $567.5 million in economic impact, according to one study. Sgro was using that number, but the vast majority of that money hasn’t already been lost, like he claimed it had been. We rate this claim False.

That wording is interesting: “It’s true that the state might eventually lose up to $567.5 million in economic impact, according to one study.”
