Super Micro Computer, a server builder that has found a home in the 401(Ks, IRAs, and brokerages of millions of American investors, has been hit hard by controversy. The company was recently forced to settle with the Securities and Exchange Commission (SEC) for allegedly overstating revenue and understating expenses, but continued its growth. Following its inclusion in the S&P 500 in 2024, Super Micro's stock rose over 2,000% over four years. However, Ernst & Young, the company's auditor, dropped them due to concerns about internal governance, controls, compliance, and financial representations. Despite these issues, SuperMicro's stock fell nearly 30% on Friday after Co-Founder Yih-Shyan "Wally" Liaw was charged with selling $2.5 billion worth of the company’s servers to China in violation of export control regulation. The case does not explicitly name Super Micro for violating export controls.
