Just to clarify, the statement Mobileye made was not an earnings release, it was a warning. Also, this looks like a classic case of a manufacturing company thinking higher customer inventories were the new normal, and it was apparently just a transitory policy, and it's almost certain not every customer acted in concert, so it probably took some number of months for the tidal wave of order cuts to build.
As for the conspiracy theories of "financial engineering", I've seen that question come up before in start-ups, but you don't see it in a US publicly listed company. (In fact, some US-listed Chinese and Hong Kong companies got in trouble with the US PCOAB over audit deficiencies last year.) Mobileye is an Israeli company, but since they're listed on NASDAQ they're subject to the very strict rules and potential penalties of the US Securities and Exchange Commission. And no major US audit firm is going to sign off on that sort of hanky-panky either. So I'm thinking the most likely scenario is this was just a case of wrongly thinking the new normal of high customer inventory levels, as opposed to just-in-time deliveries, would last a lot longer than it did.
