About 12 years ago I bought some shares of Zoltek[ZOLT].
They said Carbon Fiber would be big for making Commercial Planes and for other things.
I held them for 3 to 5 years and finally gave up when I saw the competition[mostly overseas].
A few Years later they merged with Toray Industries, Inc.
Toray has offices in Tokyo and Osaka.
I would buy shares of GTI only if I had inside information that they were to be bought out next week.
If I was a holder of this stock and I got in at a low price, then I would ponder whether I would sell them or wait another 3 years for the competition to buy them out[at a small premium to present share price]..
