NEW YORK, December 29, 2025, 21:04 ET — Market closed
- Super Micro Computer shares closed down 1.8% at $30.08, tracking a late-year pullback in tech.
- An SEC filing said operations SVP George Kao will retire on Dec. 31 and engineering executive Tom Xiao will take over.
- Investors are watching for follow-on disclosures on the transition and year-end macro data that can sway risk appetite.
Super Micro Computer (SMCI.O) shares fell 1.8% on Monday to close at $30.08 after the server maker disclosed an operations leadership change in a regulatory filing. 1
The change matters because Super Micro’s growth story depends on execution — building and shipping complex, high-powered servers used in artificial intelligence data centers. The company has faced investor scrutiny this year after it cited delivery delays tied to last-minute design changes. 2
Monday’s move also came as investors trimmed exposure to large technology stocks that have led 2025’s rally, leaving little appetite for risk ahead of the New Year. Wall Street’s main indexes ended lower, weighed down by AI-linked names. 3
In a Form 8-K, Super Micro said George Kao, senior vice president of operations, informed the company he will retire on Dec. 31, 2025. The report listed Dec. 22, 2025 as the date of the earliest event. 4
Tom Xiao, senior corporate vice president of engineering, will assume Kao’s responsibilities, the filing said. The company said it does not anticipate disruption to its operations or strategic roadmap. 4
Kao will remain as a consultant to assist with the transition, and Super Micro said it will disclose the terms of that arrangement in an amendment to the 8-K. The report was signed by CEO Charles Liang on Dec. 29. 4
Super Micro shares were little changed after the closing bell, last at about $30.01 in after-hours trading, according to Yahoo Finance. 5
The broader tape was soft. Nvidia (NVDA.O) slipped 1.2% as U.S. stocks ended down to start the final week of the year, Reuters reported. 3
“This is not the beginning of the end of the tech dominance, it’ll turn out to be a buying opportunity,” said Hank Smith, director and head of investment strategy at Haverford Trust. 3
Super Micro traded between $29.94 and $31.14 during Monday’s session. 1
The San Jose, California-based company sells servers and storage systems and has positioned itself as a supplier of AI GPU platforms — machines that use graphics processors to train and run AI models. In November, it missed quarterly profit and revenue estimates and pointed to delayed deliveries tied to design changes. 2
In October, Super Micro cut its fiscal first-quarter revenue forecast, saying customer delivery schedules for large AI-related deals shifted and pushed some expected revenue into the next quarter, Reuters reported at the time. 6
Investors will look for any follow-on disclosure around the consulting arrangement and whether the leadership transition has any impact on manufacturing cadence as the company works through large customer programs. 4
Before next session
Markets are set to stay sensitive to year-end positioning and a light calendar, with Federal Reserve meeting minutes and weekly jobless claims later in the week among the few scheduled U.S. catalysts cited by Reuters. 3
Super Micro’s fiscal second quarter ends Dec. 31. The company’s last outlook called for net sales of $10 billion to $11 billion and non-GAAP profit of $0.46 to $0.54 per share for the quarter. 7
The company has not announced its next earnings date; Wall Street Horizon lists Feb. 9, 2026 after the market close as an unconfirmed estimate based on reporting history. 8
For traders, the $30 area is the near-term line in the sand after Monday’s close. A dip below the day’s $29.94 low would extend the short-term slide, while a move back above $31 would suggest buyers are returning. 1
