Could be a bunch of things. Alexza said the last one was a routine meeting in NY.
Could be getting a proper valuation of the company for a new report
Could be hired by Alexza to consult on upcoming business decisions
But a small chance that there may be a deal in the works. I say maybe, because anything is possible. Roth could have been hired by a third party to get a solid valuation on Alexza, Adasuve in the US and now in the EU with this trip. Or Alexa could be putting together there own valuation, maybe for a sale, merger or royalty purchase. No idea with this company...
