NEW YORK, December 31, 2025, 18:49 ET — After-hours
- Super Micro Computer shares were down 1.3% at $29.27 in late trading.
- A recent SEC filing said operations SVP George Kao will retire on Dec. 31, with engineering executive Tom Xiao assuming his duties.
- The stock tracked a year-end dip in tech as U.S. markets head into the New Year’s Day holiday.
Super Micro Computer shares slid on Wednesday in thin year-end trading, as investors weighed a leadership change disclosed in a regulatory filing and a broader pullback in technology stocks.
The move matters because Super Micro’s valuation has remained tightly tied to confidence in execution — shipping high-end server systems on time while managing margins in a competitive AI hardware market.
It also lands as the company closes its fiscal second quarter on Dec. 31, setting up a fresh read on demand and delivery cadence when it next updates investors.
Super Micro stock was down 1.3% at $29.27, after trading between $29.03 and $29.86 during the session.
Wall Street ended the final session of 2025 lower, with technology among the laggards, a backdrop that pressured many AI-linked names. “It’s perfectly fine in any bull market to have moments of cost,” said Giuseppe Sette, co-founder and president of Reflexivity. 1 1
In an 8-K filing — a current report companies use to disclose major events — Super Micro said George Kao, senior vice president of operations, will retire on Dec. 31. The filing said Tom Xiao, senior corporate vice president of engineering, will assume Kao’s responsibilities, and Kao will remain as a consultant during the transition. 2 2
Traders said operational leadership is closely watched at hardware makers, where supply-chain management and manufacturing throughput can swing quarterly results.
Super Micro’s slide also came alongside softer trading in key AI and server ecosystem stocks. Nvidia was down 0.5%, Dell fell 1.6%, and Hewlett Packard Enterprise dipped 0.2% in late pricing.
Investors are now looking for the company’s next update on results for the quarter ended Dec. 31 and whether performance aligns with the revenue range the company previously laid out for fiscal Q2. 4
U.S. stock markets are closed on Thursday for New Year’s Day and reopen on Friday, which can further reduce liquidity and amplify moves in volatile names. 3 3
On the charts, traders were watching the round-number $30 level after the stock spent much of late December chopping around the high-$20s to low-$30s range.
Next catalysts include any amendment to the 8-K detailing the consulting arrangement, and the company’s timing and tone for its next earnings release and outlook update as 2026 begins.
