A company I bought stock in is awarding preferred shares to common stock holders

I’m totally in the weeds with this.

Basically this medicinal marijuana company I bought stocks in started buying up a bunch of crypto and renamed itself in the process. As a way to celebrate their rebranding and acquisition of assets, they announced a special dividend of one preferred share for every 1000 common shares held before November 25, 2024. I have like 20000 shares.

I have no idea what this means. What’s a preferred share? How do I collect on this? Are they just going to hand it over? Do I contact them? Will it just appear in my portfolio one day? Am I trading my common shares for preferred shares? Or do they give me preferred shares in addition to my common stock.

Anything you can tell me would be helpful. Thanks.
