Ann: AGM - Chairman's Statement and CEO Presentation, page-21

Collaborations dont just take 5 mins. They are clearly happening in the back ground. Large companies don't just flick each other an email with a thumbs up. They have to include a lot of sensitive information and would require hard copies and multiple signatures. They would include some short term Due Dil from their technical departments etc. Add some lawyers in there and that's why its not done overnight. These corporations are probably very LARGE. I am sure these big guys wont be questioning the Deakin tech, its paper work no doubt.
Its only been listed 8 weeks and done its first deal for 400 trucks minimum in an emerging multi billion dollar industry. They have already signed NDA's with other companies according to the CEO. If these guys drop out a big household name or two, then it should provide some serious cred and hopefully underpin a stronger stock price moving forward.
They have $50m in the bank and getting on with it. All good so far.
