Talking point: Super Micro makes hardware for data centres around the world, including servers containing Nvidia’s in-demand AI chips. The firm reported net sales of US$14.9 billion in its fiscal year ended June 30, more than double the previous year. In mid-March, Super Micro’s stock was added to the S&P 500 Index, after a huge runup in its share price at the start of the year. But it’s since surrendered all of those gains amid late regulatory filings and short-seller attacks. The U.S. Justice Department is reportedly investigating the company after a former employee alleged accounting violations. Super Micro said it disagreed with EY’s decision to resign, and that a special board committee is reviewing the firm’s internal controls and governance.
