All of that is true, but I think it misses the point of the small San Antonio deployment. My guess is that is a "proof of concept" to see what kind of demand there is for their shrimp in a retail direct-to-consumer location as opposed to growing shrimp for retail chains to sell pre-packaged, or mail order, or in bulk to casinos (Vegas). Clearly that nominal revenue does not justify SHMP's market cap.
The real key is whether they can profitably scale the business given access to the working capital required to grow it. That is what the SPAC deal provides. Whether they can be successful remains to be seen, but if they fail it no longer will be due to being under-capitalized.
I still expect some further price weakness into year end and before the deal closes.
