Material changes and business mix
- Revenue rose by $215.0 million from 2020. The company attributed growth to broad demand and gains in appliances, mobile-device chargers, and industrial applications, supported by product availability and customer demand.
- Gross margin rose from 49.9% to 51.3%; manufacturing efficiencies were mostly offset by an unfavorable end-market mix.
- Revenue mix in 2021 was communications 30%, computer 10%, consumer 32%, and industrial 28%. Computer share increased from 7%; industrial share declined from 30% in 2020.
- Customer and channel concentration increased: the top ten customers represented 78% of revenue, versus 62% in 2020. Avnet accounted for 30% and Honestar Technologies for 16%. Distributors generated 75% of revenue; international sales were 98%.
- Operating cash flow in 2019 was $224.5 million and net income was $193.5 million, including a $169.0 million gain from the ON Semiconductor litigation settlement. This makes 2019 earnings an unusual comparison.
Outlook, risks, contingencies and unusual items
- Outlook: The filing provides no specific revenue or earnings guidance. Management described the business as fundamentally sound with strong long-term growth prospects and said it planned continued R&D investment, dividends, and repurchases, subject to business conditions and board discretion.
- Supply chain and COVID-19: The company reported temporary shutdowns at certain assembly and test subcontractors, but said mitigation measures prevented a material effect on results to date. Renewed restrictions and supply disruptions remained risks. It relies on three wafer foundries; management estimated qualifying an alternate source could take 12–24 months.
- Demand and execution: Short-term customer orders can be canceled or rescheduled, and distributor sales limit visibility into end demand. Competition, pricing pressure, customer concentration, end-market cyclicality, product development, and international exposure could affect results.
- Legal matters: Ongoing patent disputes include Opticurrent litigation, with a prior reduced $1.2 million damages award under appeal, and CogniPower proceedings. The company could not estimate a loss or range for ongoing litigation; adverse outcomes could involve damages, licensing costs, or restrictions on products.
- Revenue estimates: The reserve for distributor ship-and-debit claims rose by $15.2 million during 2021, primarily reflecting higher distributor inventory and anticipated claims. Larger-than-estimated claims could affect revenue and results.
- Tax and currency: California tax years 2018 and 2019 were under audit. A 10% U.S. dollar move against the yen could eventually change gross margin by approximately 1.0%, all else equal.
- Capital returns after year-end: The remaining $67.3 million repurchase authorization was used in January 2022; the board then authorized an additional $100 million. The quarterly dividend was raised to $0.18 per share for 2022.
- Audit: Deloitte issued unqualified opinions on the financial statements and internal control over financial reporting; it reported no critical audit matters.
