In another portion of the forum, folks are discussing this topic. I am unable to reply to comments in that section.
FDIC insurance coverage and mergers of Insured Depository Institutions is described by the FDIC at https://www.fdic.gov/deposit/diguidebankers/documents/merger-idis.pdf
(For those who only have CDs, see the section titled "Time Deposits".)
If you have questions after reading the entirety of the "Mergers of IDIs" document, I would suggest that you contact a specialist at the FDIC. My experience with specialists at the FDIC is that they are excellent, as are specialists at the NCUA.
I would not pay much attention to anything told to me by an employee of a financial institution. I wouldn't even bother asking one. I would pay some attention to any written documents issued by involved IDIs.
