This is not surprising. Hindenburge Research (a short seller) documented SuperMicro’s problems in August 2024 (https://hindenburgresearch.com/smci/).
That's the risk with relying on short sellers' reports. Very frequently, the short seller is lying.
With SuperMicro, the auditor's withdrawal is worth 100x the short sellers' report. This is because it is very common for short sellers to make up claims about a company's financials, but it is very rare for an auditor to voluntarily withdraw.
Is there any public data on how much money they have made, doing so?
