Lexaria and Altria has collaborating long now - and Altria is to decide if they want to continue with the project and pay Lexaria some millions if they shall exercise there rights (see Altria deal) or not.
The new deal with BAT, can be a factor in the Altria-Lexaria collaboration. The fact is; 2 of the top 3 (!) tobacco companies is looking to work with and invest in Lexarias technology.
Lexarias hand got even stronger towards Altria, when BAT joined smile. I can see different scenarios of value gain for Lexaria, both in the short and long term. Example; one of the 2 tobacco giants might try to buy Lexaria, to protect the technology and get monopoly on it (many applications).
Time will tell; 50% plus value gain in stock price within 3,5 months
