Cash from investing activities was a net use of $28.3 million, and financing activities used $17.2 million, including $25.1 million of dividends.

Material changes versus the prior period
- Revenue rose $67.6 million, or about 16%, reflecting growth across all end markets. Communications increased to 30% of revenue from 26%; consumer and industrial shares declined to 33% and 30%, respectively.
- Gross margin fell 0.8 percentage points, primarily because of a less favorable end-market mix, including higher revenue from lower-margin markets.
- Operating income and net income were substantially lower than in 2019, which included a $169.0 million net gain from a favorable ON Semiconductor litigation settlement. Excluding the effect of that settlement, the headline year-over-year earnings comparison is not representative of underlying operating performance.
- Operating cash flow declined from $224.5 million to $125.6 million. The 2019 amount benefited from the litigation settlement; 2020 cash flow also reflected higher receivables and inventories. Capital expenditures rose to $70.6 million, principally for equipment and a German design-center building.
- Research and development expense increased to $81.7 million, mainly from compensation, headcount and product-development equipment. Stock-based compensation increased to $30.9 million from $23.3 million.
Quarterly performance and outlook
In Q4 2020, revenue was $150.7 million and net income was $27.3 million, versus $114.5 million and $158.3 million, respectively, in Q4 2019. The prior-year quarter included the ON Semiconductor settlement gain, materially distorting the net-income comparison. The filing does not provide a specific numerical revenue or earnings forecast. Management described demand as strong despite the pandemic downturn, cited long-term growth prospects, and said it intended to continue investing in R&D and to continue its dividend and repurchase programs, subject to board discretion and business conditions. In January 2021, the board declared quarterly dividends of $0.13 per share for 2021.
Risks, contingencies and unusual items
- COVID-19 and supply chain: Pandemic restrictions temporarily disrupted some assembly and test subcontractors and delayed shipments, though management said mitigation measures prevented a material effect on 2020 results. Future demand and disruption remain uncertain.
- Supplier dependence: The company relies on three foundries for most wafer production. It estimates qualifying an alternative source could take 12–24 months; capacity, yields and specialized assembly materials are additional risks.
- Customer, channel and geographic concentration: Distributors generated 75% of 2020 revenue; the top ten customers represented 62%. Avnet and Honestar represented 19% and 11%, respectively. International sales were approximately 98% of revenue, with Asia an important manufacturing and sales region.
- Intellectual-property litigation: Unresolved Opticurrent and CogniPower matters could result in damages, licensing costs, product restrictions or other adverse effects. The company said it could not estimate a loss or range of loss for the ongoing matters. It also reported significant legal costs associated with IP litigation.
- Other exposures: Price competition, short-term and changeable customer orders, inventory obsolescence, product defects, foreign-exchange movements, tax uncertainties and reliance on key personnel may affect results. A 10% change in the U.S. dollar versus the Japanese yen could eventually change gross margin by about 1.0%, all else equal.
- Tax and controls: Unrecognized tax benefits were $21.1 million; the company maintained valuation allowances on certain deferred tax assets. The auditor issued unqualified opinions on the financial statements and internal controls, and management reported effective disclosure controls and internal control over financial reporting.
Important facts for investors to verify
- Assess earnings and cash-flow trends apart from the one-time $169.0 million 2019 settlement gain, and review the drivers of 2020 gross-margin contraction.
- Track inventory, receivables, distributor stock levels and customer concentration, particularly the increased share of revenue from the two largest named customers.
- Review foundry capacity, subcontractor resilience and progress on supply-chain diversification, given the estimated 12–24 months to qualify an alternative foundry.
- Follow developments in the Opticurrent and CogniPower litigation and any changes to the company’s ability to estimate potential losses.
- Monitor the returns from the elevated 2020 capital spending, the sustainability of cash generation and the board’s future dividend and repurchase decisions.
