SiTime Stock Jumps 28% on Data-Center Demand Surge
SiTime Corporation shares climbed 27.9% to $797.31 on Thursday after the Santa Clara chipmaker posted first-quarter revenue of $113.6 million, up 88.3% year over year, and raised its full-year forecast. The stock hit an intraday record.
The company makes precision timing devices-components that synchronize chips, servers, and data links. As AI workloads intensify, demand for these components has accelerated sharply.
Where the Growth Is Coming From
SiTime's communications, enterprise and data center division generated $75.7 million in revenue, accounting for 66.6% of the total. That segment surged 158% year over year, driven by AI infrastructure demand tied to optical modules, switches, SmartNICs, and accelerator platforms.
Chief Executive Rajesh Vashist said precision timing is becoming "a system-level requirement" as AI infrastructure scales. He noted that inference infrastructure-which runs trained AI models-requires two to four times more timing content per system than training infrastructure.
Despite strong revenue growth, SiTime posted a GAAP net loss of $5.2 million for the quarter. On a non-GAAP basis, the company reported net income of $38.9 million, or $1.44 per diluted share.
Guidance and Analyst Response
SiTime projects full-year revenue growth of at least 80%. For the June quarter, the company expects revenue between $140 million and $150 million, with non-GAAP earnings per share between $1.85 and $2.00.
Needham analyst N. Quinn Bolton raised his price target to $850 from $450, citing signs the company was gaining new customers and expanding business with existing ones. UBS analyst Timothy Arcuri lifted his target to $775 from $675, calling SiTime's valuation "increasingly reasonable."
Competitive Pressure and Margin Risk
SiTime agreed earlier this year to acquire timing assets from Renesas Electronics in a deal valued at up to $3.2 billion. CEO Vashist told Reuters the technology could eventually be used in billions of Renesas chips, but revenue from that deal is still years away.
The company faces competition from Renesas, Texas Instruments, and Microchip Technology. Higher average selling prices supported this quarter's results, but SiTime cautioned that rivals pose risks including price pressure and margin compression.
Chief Financial Officer Beth Howe flagged to analysts that a larger consumer product mix later this year could "modulate" gross margins. Customer orders remain subject to change or cancellation with minimal notice.
For sales professionals, the broader takeaway is clear: AI data-center infrastructure is creating real demand for specialized components, not just processors and memory. SiTime's challenge now is converting this surge into sustainable growth while defending margins against larger competitors.
