    GSTX's subsidiary Quartz & Silicon Materials Company (QSM USA) was awarded a $45 million California Competes Tax Credit over five years to support planned silicon ingot and wafer manufacturing projects - a real state incentive, but one earned only against future California tax liability and tied to investment/job milestones the company has not yet shown it can fund, given its history of unfunded MOUs and years of losses.

    New management (in place since the 2017 reverse merger) discovered a fiscal-2015 annual report had never actually been filed, and when it was finally filed in 2018 it was never sent to the outside auditors for required review - the company disclosed that report should not be relied upon.
