SEC filingRevenue grew 45% YoY to $83.6M with gross margin expanding to 53.5%, driven by product mix and volume, while operating expenses rose 12%.
SiTime's revenue for Q3 2025 increased 45% year-over-year to $83.6 million, driven by higher sales volume and improved average selling prices due to a shift in product mix toward higher-value Precision Timing solutions. Gross profit rose 52% to $44.7 million, with gross margin expanding 240 basis points to 53.5%. The margin improvement was attributed to favorable product mix (130 bps) and better overhead cost absorption as a percentage of revenue (110 bps). Operating expenses grew 12% to $60.7 million, driven by increases in research and development (R&D) and selling, general and administrative (SG&A) costs. R&D expense rose 13% to $30.0 million, primarily from higher headcount-related stock-based compensation and engineering spend for new product development, partially offset by non-recurring engineering contra-expense. SG&A expense increased 21% to $30.6 million, reflecting higher headcount costs, sales commissions on increased revenue, and consulting fees. Acquisition-related costs decreased sharply by 95% to $0.1 million, as lower accretion of earnout and consideration payable reduced the expense. Interest income increased 50% to $8.3 million, benefiting from a higher average investment balance following the June 2025 follow-on public offering.
The MD&A does not provide segment-level revenue breakdown. However, management highlights strong growth in AI datacenter deployments as a key driver, along with momentum in communications (5G small cells) and automotive markets. The acquisition of Aura's clock products in late 2023 expanded SiTime's total addressable market and enabled a more complete timing portfolio. The company's product mix continues to shift toward higher-performance solutions, supporting gross margin expansion.
Forward-looking statements emphasize SiTime's strategy to focus on oscillators, clock ICs, resonators, and timing synchronization solutions, with plans to expand presence across target markets. Management expects to continue investing in R&D and sales to drive growth. The company believes its existing cash and short-term investments ($809.6 million combined) are sufficient to meet operating cash needs for at least the next 12 months. No specific financial guidance is provided. The MD&A acknowledges potential macroeconomic headwinds and supply chain risks but highlights the secular trend toward higher-speed data transfer and environmental resilience as long-term demand drivers.

The commitments are scheduled: $4.7 million in the remainder of 2025, $6.9 million in 2026, $5.0 million in 2027, and $12.6 million in 2028. Additionally, sales-based earnout liabilities from acquisitions total $90.6 million ($29.5 million current, $61.1 million non-current).
Capital expenditures (capex) were $39.6 million for the nine months ended September 30, 2025, representing 18.6% of revenue, reflecting investment in lab and manufacturing equipment. There are no share buybacks or dividends. The company completed a follow-on public offering in June 2025, issuing 2.0 million shares for net proceeds of $387.3 million, bolstering its cash position.

Operating cash flow (CFO) of $61.8M far exceeded net loss of ($52.1M), driven by substantial non-cash charges: stock-based compensation $79.1M, depreciation/amortization $28.8M, and inventory write-down $3.9M. Working capital changes provided a net $1.7M inflow, mainly from accounts receivable decrease ($15.7M) offset by inventory build ($14.3M). Capex intensity is high at $39.6M (64% of CFO), reflecting significant investment in property and equipment. Free cash flow (CFO minus capex) would be $22.2M, though not explicitly stated. Financing activities provided $365.6M, largely from stock issuance ($433.1M) net of offering costs ($16.1M) and tax withholdings ($41.3M). No share repurchases or dividends were disclosed. The massive improvement in CFO from $9.7M in prior year is notable, primarily due to reduced net loss and favorable working capital swings.
