Company sold— will I lose all my PTO?

My company was sold (I’m not supposed to know) and we will have a new parent company at the end of the month. I know the purchasing company has an accrued/earned PTO policy whereas our current parent company gives you a set number of days off renewing on your anniversary date.

I’m wondering if I should try and burn up my PTO now if there is a chance I will lose it. On the other hand, if we keep it for the rest of the year or something I don’t want to be without PTO… Has anyone who has gone through a company purchase have any advice?

I know there is no straight answer since it could vary by company, but any advice is appreciated.
