An announcement of a licensing agreement for the tech would do it in the short term. That could come in the next 6 months.
Sales figures for their own shrimp sales will do it in the long term, that is 6 to 12 months out.
Either of those might show limited income if it's a single licensing agreement or a single shrimp harvest sale. But both show commercial viability for future income which will increase the stock price.
A buy out agreement could come at any second, which would do it. But I see that as less likely. I just don't see it as the direction they want to go. But you never know.
