Revenue growth reflected a 34% increase in shipment volume and a 40% increase in average selling price, driven by product mix, pricing and demand from new and existing customers. Gross-margin expansion reflected higher volume, higher ASPs and lower manufacturing costs as a percentage of revenue.
Research and development expense increased 65% to $52.1 million, while selling, general and administrative expense increased 56% to $54.5 million. Stock-based compensation expense totaled approximately $30.0 million in 2021. Accounts receivable were $38.4 million and inventories were $23.6 million at year-end.
Financing cash flow of $460.6 million primarily reflected net proceeds from two 2021 follow-on equity offerings. The company issued 2.8 million shares and raised net proceeds of $181.6 million in February and $279.0 million in November. No dividends were paid or planned for the foreseeable future.
Material changes versus the prior comparable period
- Revenue increased from $116.2 million to $218.8 million, and the company moved from an operating loss and net loss to operating and net profitability.
- Gross margin increased from 50% to 64%; management attributed the improvement mainly to volume, ASP and product-mix changes.
- Cash increased by $485.9 million during the year, primarily from equity offerings and operating cash generation.
- Capital investment increased substantially, including $30.9 million for property and equipment, largely test and manufacturing equipment supporting demand.
- Property and equipment, net increased to $37.9 million from $11.7 million.
- MegaChips’ ownership declined to approximately 24% from 43.7% at December 31, 2020. The MegaChips distribution agreement was terminated effective November 3, 2021.
- The company expanded its workforce to 279 full-time equivalent employees, including 137 in research and development.
Outlook, commentary, risks and unusual items
Management expects continued investment in research and development, sales and marketing, new products, clock ICs and timing synchronization solutions. It believes existing cash and cash equivalents are sufficient for at least the next 12 months. No specific revenue or earnings guidance was provided.
- Supply constraints: Industry-wide shortages affecting analog foundries, including TSMC, and outsourced assembly and test providers limited the company’s ability to satisfy demand. Management stated that supply constraints may have contributed to 2021 revenue and margin growth and may not be sustainable.
- Margin pressure: The company expects manufacturing costs to increase in fiscal 2022. Gross margin remains sensitive to product mix, pricing, yields, wafer costs, packaging and testing costs, and inventory write-downs.
- Customer concentration: The company has substantial exposure to Apple and relies on a small number of distributors. Orders generally may be cancelled, reduced or rescheduled with little notice.
- Supply-chain dependence: Bosch is the primary MEMS wafer supplier under an agreement extending through February 2027, while TSMC is the primary supplier for analog circuits. Most other manufacturing relationships are based on purchase orders rather than long-term contracts.
- COVID-19 and geopolitical risk: The pandemic caused some manufacturing, shipment and sales disruption. International operations and suppliers expose the company to risks involving Taiwan, Malaysia, Thailand, Germany, Ukraine, Russia, tariffs, export controls, sanctions and transportation.
- Warranty and contingencies: SiTime provides a limited lifetime product warranty; the year-end warranty reserve was less than $0.1 million. Purchase commitments totaled $5.4 million, primarily for design and simulation licenses, payable through June 2024.
- Litigation: A patent infringement case brought by VTT was resolved in SiTime’s favor after the Federal Circuit affirmed the district court judgment on June 10, 2021. The company believes the matter is fully resolved.
- Tax attributes: The company reported federal and state NOL carryforwards of approximately $259.6 million and $64.5 million, respectively, but maintained a full valuation allowance against deferred tax assets.
- Subsequent event: On February 23, 2022, the company adopted a 2022 Inducement Award Plan reserving 250,000 shares.
Most important facts for investors to verify
- Whether 2021 revenue and gross-margin growth can continue after industry supply constraints normalize and manufacturing costs rise.
- Current revenue attributable to Apple and the company’s ability to diversify its end-customer base.
- Capacity, pricing and continuity arrangements with Bosch, TSMC and outsourced assembly and test providers.
- Inventory levels, reserves and demand forecasts, particularly given inventory valuation was identified as the critical audit matter.
