Super Micro Computer Sales More Than Doubled Last Quarter — But Here’s Why I’d Still Avoid the Stock

Super Micro Computer reported a sharp rise in revenue, with third-quarter fiscal 2026 net sales reaching $10.2 billion, up 123% year over year for the period ended March 31, 2026. The company has benefited from strong demand for infrastructure used in artificial intelligence, especially servers and related technology products, and its top-line growth has been exceptional in recent years.

Despite that momentum, the article argues the stock may still not be an attractive buy. The main concern is profitability. Super Micro’s margins remain very thin, with gross margin in the latest quarter just under 10%. Even though margins have improved somewhat, the company still keeps only a small share of its sales after covering the cost of revenue.

That weakness becomes clearer over the past nine months. Revenue climbed 72% to $27.9 billion, but gross profit increased only 21% to $2.3 billion. This gap suggests the company is highly dependent on continued AI-driven demand to maintain growth, while limited margins leave little cushion if sales slow or costs rise.

The article also points to valuation and business risks. Super Micro stock trades at about 19 times trailing earnings, which may appear inexpensive relative to the broader market. However, the lower multiple does not fully offset concerns about the quality and durability of its earnings. The company has also faced accounting and control issues in the past, including a previous auditor resignation that raised questions about its reporting processes. Although no major new problems have emerged recently, those concerns continue to cast a shadow over investor confidence.

Taken together, the article concludes that Super Micro Computer’s rapid sales growth is not enough to make the stock compelling. Low margins, reliance on AI demand, and lingering governance concerns make the shares look riskier than they are worth for many investors. The piece suggests that other stocks on a separate list of top picks may offer better long-term potential than Super Micro.
