The company has incurred restructuring costs and employee terminations costs for several quarters. Not to mention massive write-down for other things. Layoffs started several quarters ago. Selling of assets and "restructuring" started several quarters ago and sped up once booth and battley were gone.
So, no, these are not one time adjustments. If you think the adjustments will end with Q1 2021, then your use of the adjusted, adjusted numbers can be helpful. I don't think the adjustments will end any time in fiscal 2021.
BTW, revenue and revenue sources are the most important metric for me with this company. In my opinion, they will be playing games with expenses and write-downs for quite some time.
