The AO Smith announcement could be a game changer for WDT. Its a huge company and even 1% of AOS sales could make a material difference to WDT. Maybe it was a good thing that WDT never hooked up with these guys 4 years ago though Ross Green stated that it would have led to immediate profitability. Still WDT is a stronger and leaner beast now with its own plans and less likely to mildly submit to what ever AOS wants. They have proved that they can survive on their own(with shareholder support) and this was not the case 4 years ago.
Am thinking that the long term future is much more assured now and feeling a bit more confident. Lets see how the sales work out.
