If the posters are being truthful about the letter
Then I don't see any scary bad news here. At all.
No reverse split, no massive dilution of shares, no massive increase in debt, no legal issues, no unusual problems of any kind.
Just an update to tell shareholders that their plans are moving forward without any major concerns. If anything, this letter is a positive. When the Market is uncertain about a company's future, the stock suffers accordingly. Since this letter will clear up some uncertainty, the Market should react in a positive way.
It sounds like the focus of the company right now is to "get the word out" about the need and benefits of their products. This may still take some time. But once the ball gets rolling, and these devices gain wider public acceptance in the car/truck industry, growth and profits will follow close behind.
I wouldn't be surprised to see an unexpected partnership, merger, or buyout of ATWT in the future if more of these devices are required by law.
Things could also change very fast if the need for ATWT's safety products are suddenly in the News because of a high profile accident or death. One that might have been avoided by installing an ATWT device.
