In My Opinion- for every major tower erected add $1.64 to $11.62 after dept because non-toxic. I am not sure about the Coal Plant Chimney Retrofiting side of the business. Depending on the company model, the value of the stock can fluctuate. If this stock starts being more secure I would say The &11.62, but if they keep filing SEC with form 4 instead of 8k I would assume a price around $1.64 that can go poof if the SEC suspendes SWET.
