SiTime Corporation is offering $1,200,000,000 principal amount of 0% Convertible Senior Notes due 2031 as permanent financing to fund, in part, its pending acquisition of Renesas’s timing business. The notes mature on June 15, 2031 and convert at an initial rate of 0.9611 shares per $1,000 (approx. $1,040.47 per share).
The offering is expected to yield net proceeds of about $1.176 billion before expenses (98.0% of the offering) and includes an underwriters’ option for up to $150,000,000 additional notes. Conversion, redemption and fundamental-change provisions, and capped-call hedges are described in the prospectus supplement.
SiTime Corporation proposes a primary offering of $1,100,000,000 principal amount of % convertible senior notes due 2031. The notes bear interest semiannually, are convertible into a stated conversion rate of shares per $1,000 principal (approximate conversion price per share shown in the supplement), and mature on June 15, 2031 unless earlier converted, redeemed or repurchased.
The supplement states holders may convert prior to March 15, 2031 only if specified market‑price, trading‑price, redemption or corporate‑event conditions are met; thereafter conversions are permitted until two scheduled trading days before maturity. The issuer may redeem the notes on or after June 20, 2029 subject to a 130% stock‑price test, and may perform a cleanup redemption if less than 25% remains outstanding.
The offering is disclosed as permanent financing to replace a previously committed 364‑day bridge facility; SiTime expects to use net proceeds to fund approximately $1.5 billion cash consideration for an agreed acquisition from Renesas, to pay capped call costs, and for general corporate purposes. The supplement includes pro forma financial data reflecting the Acquisition and the offering.
SiTime Corporation is moving forward with its planned acquisition of Renesas’ Timing Product Business and has filed detailed historical and pro forma financial information. The deal terms include $1.5 billion in cash plus 4.13 million newly issued shares of SiTime common stock, subject to a VWAP-based collar.
The Timing Product Business generated $207.744 million in product revenue in 2025, with product revenue less direct expenses of $76.153 million, and $69.306 million of revenue in the three months ended March 31, 2026. As of December 31, 2025, net assets to be acquired totaled $449.476 million, including $382.299 million of goodwill and $58.427 million of intangible assets.
Pro forma statements show how SiTime and the Timing Product Business would look on a combined basis, assuming the acquisition and approximately $1.25 billion in permanent financing were completed, with significant new goodwill and intangibles and interest effects from the planned debt and convertible notes structure.
