Is this company publically traded and you found the info legally? If so, please see if you can take a position in the market before you disclose.

Secrets are worth so much money, and knowing a stock will most likely move a certain direction at a specific time of your choosing has tremendous value.

You most likely don't owe any company a disclosure.

Hire a lawyer or do your own research on how to profit from this in a legal way. That's my advice.
