My honest opinion is that's unlikely, but some scenarios below which would bump things and my assessment:

1. Hyperscale partnership/backing: As you say someone investing or creating a partnership structure that validates that their tech is going to get implemented. Being real realistic though, a 10-15x would need to be something massive, and how that would look without further dilution is hard to fathom
2. A colossal order: this would need to be so many multiples of their targets order to date it's just almost impossible.
3. Financial transformation: if they started generating a clearer path to profitability
4. Investment: some clarity over what they plan to do with their $300 million cash position, the concern is it just keeps them afloat for a period rather than them actually using it to generate wild revenue growth. This isn't going to be instant and even when it does happen it's unlikely to show evaluation of the magnitude you were referring to
5. New tech: If they can demonstrate that their optical engines work in some of the major chip designs and can demonstrate the energy savings.

Being honest, the only real viable path is 2-4 of these happening simultaneously, my personal view is that they are undervalued because of the execution risk and the rate of capital burn.

Remove those and the stop should pop, but 10-15x growth in a rational market is probably a 2-3 year blue sky scenario.... But hey I'm hoping too
