10. ​SiTime Corporation (NASDAQ:SITM)

Year-to-Date Performance: 103.01%

​SiTime Corporation (NASDAQ:SITM) is one of the best multibagger stocks to buy in 2026. On May 20, SiTime priced an upsized underwritten offering of $1.2 billion in 0% Convertible Senior Notes due 2031, increased from the initially planned $1.1 billion. The sale is expected to close on May 22, 2026, with an additional 13-day overallotment option for underwriters to purchase up to $150 million more in notes. The initial conversion price is set at approximately $1,040.47 per share, representing a 50% premium over the company’s May 19, 2026, closing stock price.

The company expects net proceeds to reach approximately $1.17 billion, or $1.32 billion if the overallotment option is fully exercised. SiTime plans to use these funds to finance a portion of its previously announced acquisition of Renesas Electronics Corporation’s timing business assets, pay $108 million for concurrent capped call transactions, and allocate any remaining funds toward general corporate purposes. The capped call transactions feature an initial cap price of $1,734.15 to mitigate potential equity dilution upon note conversion.

The registered offering is being managed by Wells Fargo Securities, Goldman Sachs & Co. LLC, Barclays, UBS Investment Bank, and Morgan Stanley, with HudsonWest LLC serving as financial advisor. ​SiTime Corporation (NASDAQ:SITM) retains optional redemption rights starting June 20, 2029, under specific stock price conditions, while noteholders retain repurchase rights at 100% of the principal amount if the company undergoes a defined fundamental change before maturity.

​SiTime Corporation (NASDAQ:SITM) focuses on developing micro-electromechanical system-based silicon timing solutions that replace legacy quartz devices.
