Super Micro Computer’s shares dropped 20% after disappointing fiscal fourth-quarter results, impacted by President Trump’s tariffs. CEO Charles Liang assured investors the company is mitigating tariff effects. CFO David Weigand noted the dynamic tariff situation. Q4 earnings were 41 cents per share, missing estimates of 44 cents, with revenue at $5.76 billion, below forecasts.

Super Micro faced a revenue shortfall in June due to working capital issues and changes from a major customer. The company previously benefited from AI server demand with Nvidia chips but has experienced slowed growth. Guidance for the fiscal first quarter fell short of estimates, expecting 40-52 cents per share on $6-7 billion in revenue, lower than projections of 59 cents per share and $6.6 billion revenue.

Super Micro forecasts full-year revenue of at least $33 billion, lower than its previous $40 billion projection but higher than the consensus of $29.94 billion. The company’s stock chart shows a decline in value for the year. CNBC’s Jordan Novet contributed to this report.
