- Revenue increased 93% year over year in Q3 and 89% for the nine-month period. Management attributed the growth to higher shipment volumes, design wins, product mix and higher average selling prices.
- Q3 shipment volume increased 33% and average selling prices increased 45% year over year. For nine months, shipment volume increased 44% and average selling prices increased 31%.
- Operating expenses increased 58% in Q3 and 57% for nine months, reflecting higher headcount, research and development investment, commissions, consulting costs and stock-based compensation.
- Stock-based compensation expense was $7.4 million in Q3 and $21.9 million for nine months, compared with $4.6 million and $10.7 million in the respective 2020 periods.
- Net cash provided by operating activities was $34.4 million for nine months, compared with $9.8 million in the prior-year period.
- Capital expenditures were $20.1 million for nine months, primarily for test and manufacturing equipment; cash paid for intangible assets was $2.4 million.
- Cash and cash equivalents were $267.0 million at September 30, 2021, compared with $73.5 million at December 31, 2020. The increase was primarily driven by the February 2021 follow-on offering, which generated $181.6 million of net proceeds.
- The company reported no outstanding debt and no interest expense in 2021 after repaying its credit facilities in 2020. Lease liabilities totaled $7.8 million, including $1.4 million current and $6.4 million non-current.
- Inventory increased to $19.6 million from $12.4 million at year-end 2020, while accounts receivable increased to $32.5 million from $24.0 million.
Material Changes Versus the Prior Comparable Period
- The company moved from losses to profitability: nine-month net income was $12.4 million versus a $11.4 million loss in 2020.
- Gross margin expanded by 14 percentage points in Q3 and 12 percentage points for nine months, primarily from higher volume, pricing and mix, with lower manufacturing costs as a percentage of revenue.
- Research and development expense rose 53% in Q3 and 58% for nine months; selling, general and administrative expense rose 63% and 56%, respectively.
- The company increased investment in property and equipment to support demand, with net property and equipment rising to $31.3 million from $11.7 million at December 31, 2020.
- Shares outstanding increased following the issuance of 1.5 million shares in the February 2021 follow-on offering. MegaChips remained the largest stockholder but reduced its ownership to approximately 31.2% from 43.7% at year-end 2020.
- Deferred non-recurring engineering liabilities totaled $4.6 million at September 30, 2021. Related payments reduced research and development expense by $0.9 million in Q3 and $1.0 million for nine months.
Guidance, Outlook, Commentary and Risks
- Management expects continued investment in research and development, sales and marketing and infrastructure. The filing does not provide a clear numerical revenue, gross-margin or earnings forecast for the next quarter or full year.
- Management stated that demand was growing, but industry-wide constraints affecting analog foundries, including TSMC, and outsourced semiconductor assembly and test providers could limit shipments and customer fulfillment.
- Management cautioned that the 2021 revenue and gross-margin increases may not be sustainable after supply constraints ease and that average selling price increases may not continue at the current rate.
- The company reported minimal supplier disruption from COVID-19 to date, but continued pandemic effects, variants, restrictions, labor constraints and customer demand changes could affect manufacturing, shipments, revenue, margins, cash flows and liquidity.
- Customer concentration remains significant. The largest end customer represented 20% of Q3 revenue and 23% of nine-month revenue; the top three distributors represented approximately 45% and 49%, respectively.
- Most sales are made under purchase orders without long-term or minimum purchase commitments, exposing the company to cancellations, rescheduling, inventory risk and quarterly volatility.
- The company relies heavily on third parties, including Bosch for MEMS wafers, TSMC for analog circuits and several outsourced assembly and test providers. Capacity, yield, quality, pricing, geopolitical and qualification risks could affect results.
- Management believes existing cash and cash equivalents are sufficient to meet cash needs for at least the next 12 months. Longer-term funding needs will depend on growth, operating investment and market acceptance; additional financing may not be available on acceptable terms.
- The company maintains a full valuation allowance against deferred tax assets. The reported effective tax rate was approximately zero for Q3 and negative 1% for nine months.
- The VTT patent litigation was affirmed in the company’s favor by the Federal Circuit on June 10, 2021, and management believes the matter is fully resolved.
- After quarter-end, on November 3, 2021, the company and MegaChips mutually terminated the non-exclusive Japan distribution agreement as SiTime pursued direct distributor relationships.
- Management reported that disclosure controls and procedures were effective as of September 30, 2021, with no material changes to internal control over financial reporting during the quarter.
