A stock I own is potentially delisting from NASDAQ. I had sold some covered calls for my shares (exp. 2025). What happens now ?

I sold covered calls for my shares , they don’t expire until 2025. My goal was to buy them back to release collateral later at a cheaper price. Now I’m learning they may potentially delist.

So what happens to the contracts if it will be traded in OTC? Should I be trying to buy to close my covered calls I sold in order to release collateral to be able to sell in OTC a sooner if I’d like ?

Once in OTC we can no longer buy back our covered calls can we ? My concern is that I will have to wait until 2025 to release collateral for my shares if it gets delisted.

I am holding this in Robinhood by the way.

Thanks !
