How do you think, in the recent decade, does the trend of such practice went up or down ?A company is taxed on their profits. If they declare a loss their tax burden is significantly decreased... and may be zero. That's why you see stories like below; where a multi-billion dollar company like General Electric paid no taxes at all in 2010.
The law states that a company can only declare a loss 2 out out five years. So imagine a scenario where a company has declared a profit the last three years. They can save a boatload of money simply by declaring a loss this year. Good accountants will structure tax returns over a number of years to maximize write-offs.
This, in turn, affects the share price, as declared quarterly earnings will be down this year. It has little to do with actual revenue, PnL, unit sales, etc.. it's all creative accounting designed to minimize tax burden.
Any kind of fundamental analysis ABSOLUTELY MUST include an investigation into a company's tax structure. It's on the short list of drivers for company valuation.

How many, actually have been caught by doing so and is the fines big enough ?
Or, this is just a smart hole in the tax system that can be exploited (?)
It brings, the already wriggled game into a new level.
(for a small retailer)
In such case, as you mentioned, revenue and sales plays much bigger role.
(probably, can't twist those numbers that easily, unless one represents NKLA or smthn)
