<div id="readability-page-1"><article>SANTA CLARA, Calif., May 19, 2026 (GLOBE NEWSWIRE) -- SiTime Corporation (“SiTime”) (NASDAQ: SITM), the Precision Timing company, today announced its intent to offer, subject to market conditions and other factors, $1.1 billion aggregate principal amount of Convertible Senior Notes due in 2031 (the “Notes”) in an underwritten offering (the “Offering”). SiTime also intends to grant the underwriters of the Notes a right to purchase, within a 13-day period beginning on, and including, the date on which the Notes are first issued, up to an additional $150 million aggregate principal amount of Notes, solely to cover over-allotments, if any. The Notes will be general unsecured obligations of SiTime, with any interest payable semiannually in arrears and will mature on June 15, 2031, unless earlier converted, redeemed or repurchased. Upon conversion, SiTime will pay or deliver cash, shares of SiTime’s common stock, par value $0.0001 per share (“common stock”), or a combination of cash and shares of common stock, at its election. The interest rate, initial conversion rate and other terms of the Notes will be determined at the time of pricing of the Offering. SiTime expects to use the net proceeds from the Offering (i) to pay for a portion of the cash consideration of the acquisition of certain assets related to the timing business of Renesas Electronics Corporation as announced on February 4, 2026 (the “Acquisition”), (ii) to pay the cost of the capped call transactions described below and (iii) the remainder, if any, for general corporate purposes, which may include working capital, operating expenses, capital expenditures and general and administrative expenses. If the underwriters exercise their over-allotment option, SiTime expects to use a portion of the net proceeds from the sale of the additional Notes to enter into additional capped call transactions and the remainder for general corporate purposes as described above. In connection with the pricing of the Notes, including the potential over-allotment Notes, SiTime expects to enter into capped call transactions with one or more of the underwriters or affiliates thereof and/or other financial institutions (the “Option Counterparties”). The capped call transactions will cover, subject to customary adjustments, the number of shares of common stock initially underlying the Notes. The capped call transactions are expected generally to reduce the potential dilution to the common stock upon any conversion of Notes and/or offset any cash payments SiTime is required to make in excess of the principal amount of converted Notes, as the case may be, with such reduction and/or offset subject to a cap. In connection with establishing their initial hedges of the capped call transactions, SiTime expects the Option Counterparties or their respective affiliates will enter into various derivative transactions with respect to the common stock concurrently with or shortly after the pricing of the Notes, including with certain investors in the Notes. This activity could increase (or reduce the size of any decrease in) the market price of the common stock or the Notes at that time. In addition, the Option Counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to the common stock and/or purchasing or selling common stock or other securities of SiTime in secondary market transactions following the pricing of the Notes and prior to the maturity of the Notes (and are likely to do so during the 40-trading day period beginning on the 41st scheduled trading day prior to the maturity date of the Notes, or, to the extent SiTime exercises the relevant election under the capped call transactions, following any repurchase, redemption or conversion of the Notes). This activity could also cause or avoid an increase or a decrease in the market price of the common stock or the Notes which could affect a noteholder’s ability to convert the Notes and, to the extent the activity occurs during any observation period related to a conversion of Notes, it could affect the number of shares, if any, and value of the consideration that a noteholder will receive upon conversion of its Notes. The Notes are being offered pursuant to a “shelf” registration statement on Form S-3 (File No. 333-277373), including a base prospectus, that was previously filed by SiTime and became effective under the rules of the Securities and Exchange Commission (the “SEC”) on February 26, 2024.
