Investors are nervous about what Super Micro’s profit warning and inventory trends could mean for the entire AI infrastructure market.

Super Micro Computer Inc. tumbled Wednesday after giving preliminary results that fell well short of analysts’ estimates, a sign its comeback plan has been slow to gain traction. Sales were $4.5 billion to $4.

Super Micro Computer (NASDAQ: SMCI), more commonly known as Supermicro, executed its first stock split on Oct. 1, 2024. That 10-for-1 split reduced its trading price from $416.40 to about $41.64 per share, while its market cap remained nearly unchanged at $24 billion.
