- SiTime shares traded down 2.3% at $726.21 recently, moving in a wide range during the session.
- Chip stocks slipped as well, with the iShares Semiconductor ETF down 1.1%.
- The May rally for the stock depends on AI data-center demand, an improved 2026 forecast, and the Renesas timing deal that hasn’t closed yet.
SiTime Corp was down 2.3% at $726.21 in late U.S. trading Wednesday, slipping as investors reassessed the chipmaker’s AI-data-center bets after a sharp run higher in May. Shares moved in a range of $705.41 to $764.00.
SiTime is starting to trade more in line with AI infrastructure plays instead of niche chip suppliers. The company makes timing chips that keep electronics running in sync, which it says are getting more critical as data centers push faster networking speeds and bring in more advanced accelerators.
Chip stocks traded lower. The iShares Semiconductor ETF slipped 1.1%. Microchip Technology was off 1.2% and Texas Instruments dropped 2.3%. SiTime’s losses were part of a bigger move in semis, not just about the company.
The bar remains high here. SiTime said earlier this month that first-quarter revenue jumped 88.3% to $113.6 million. Non-GAAP profit came in at $1.44 per share, with that figure adjusting for things like stock comp and acquisition charges. GAAP net loss was $5.2 million, or 20 cents a share.
SiTime CEO Rajesh Vashist put it plainly in the results release: “precision timing is becoming a system-level requirement” with more AI infrastructure and high-performance systems. That’s the main bull case, and the stock has traded like investors buy it. SiTime
SiTime raised its outlook. The company told analysts on the earnings call it now sees 2026 revenue growing at least 80%. For the June quarter, SiTime projected revenue in a range of $140 million to $150 million and non-GAAP EPS of $1.85 to $2.00.
Analysts reacted to the report fast. Needham’s Quinn Bolton stuck to a buy on SiTime and kept the $850 target on May 7, ratings data shows. Barclays’ Thomas O’Malley raised his call to buy and matched the $850 price target. UBS’s Timothy Arcuri held his buy rating and stayed at $775.
There’s a capital structure angle in play as well. SiTime last week set the price on an upsized $1.2 billion sale of 0% convertible senior notes due 2031, which is more than its original $1.1 billion plan. These convertibles can be swapped for shares or cash, giving the company a way to raise growth money, but raising dilution questions if the stock stays up.
Renesas is the bigger strategic move here. SiTime said in February it will buy Renesas’ timing business for $1.5 billion in cash and about 4.13 million SiTime shares. The companies expect the deal to close by the end of 2026, if it gets the needed approvals. Renesas called SiTime a leader in MEMS timing devices—tiny mechanical parts built on silicon, used instead of regular quartz timing components.
Vashist told Reuters in February that putting SiTime tech into Renesas chips could take at least a couple of years. “It could turn out to be billions of units,” he said. The timing is key for investors since the deal could change SiTime’s total market, but revenue doesn’t land all at once. Reuters
SiTime shares don’t have much cushion for a miss. Any slowdown in AI inference demand, pushed-out networking upgrades, or higher-than-expected Renesas integration costs could weigh on a company still posting GAAP losses, issuing convertible debt, and paying with stock to fund a big deal. For now, the shares trade on execution rather than just the story.
