Business context and reporting period
Power Integrations, Inc. designs and markets analog and mixed-signal components for high-voltage power conversion. This unaudited Form 10-Q covers the quarter and six months ended June 30, 2021; comparisons are with the same 2020 periods. The company reports one operating segment.
Financial performance
| Metric | Q2 2021 | Q2 2020 | H1 2021 | H1 2020 |
|---|---|---|---|---|
| Revenue | $180.1m | $106.8m | $353.8m | $216.5m |
| Gross profit / margin | $91.3m / 50.7% | $53.5m / 50.1% | $175.7m / 49.7% | $110.0m / 50.8% |
| Operating income / margin | $45.0m / 25.0% | $12.9m / 12.1% | $85.2m / 24.1% | $28.0m / 12.9% |
| Net income | $41.9m | $13.2m | $81.7m | $29.1m |
| Diluted EPS | $0.68 | $0.22 | $1.33 | $0.48 |
Revenue grew 68.6% in Q2 and 63.4% in H1 year over year; net income rose approximately 218% and 181%, respectively. Q2 gross margin improved 0.6 percentage points, while H1 margin declined 1.1 points. Management attributed the quarterly margin improvement mainly to manufacturing efficiencies, and the H1 decline to a less favorable end-market mix.
For H1, operating cash flow was $125.0m, versus $63.0m in 2020. Capital expenditures were $19.3m, compared with $21.6m. Cash and cash equivalents were $297.5m at June 30; short-term marketable securities were $217.8m, for combined liquidity of $515.3m. Working capital was $599.3m. Total liabilities were $97.5m; no borrowings were outstanding on the $75m revolving credit facility, extended to June 2026.
Material changes and management commentary
- Management cited broad demand and market-share gains, led by communications and computer applications, alongside growth in consumer and industrial markets. International sales were 98% of revenue; Asia represented 85%.
- Two distributors accounted for 29% and 19% of Q2 revenue. The top ten customers represented 80% of revenue, up from 59% in Q2 2020. Avnet alone was 29% of Q2 revenue and 46% of receivables at quarter-end.
- Operating expenses rose to $46.3m in Q2 and $90.6m in H1, primarily from higher compensation, performance-based stock compensation, headcount, and product-development costs. H1 stock-based compensation was $17.7m, versus $12.7m.
- H1 investing cash outflow was $47.9m, including net purchases of marketable securities and $19.3m in property and equipment. Financing outflow was $38.4m, including $26.4m of repurchases and $15.7m of dividends. The company repurchased about 335,000 shares; $64.9m remained authorized. The 2021 quarterly dividend was raised to $0.13 per share.
Outlook, risks, contingencies, and unusual items
No quantified revenue or earnings guidance is provided in the supplied filing text. Management described demand as strong and the business as fundamentally sound, with long-term growth prospects, and said it intends to continue investment in R&D and other growth-supporting functions. It believes existing liquidity and operating cash flow will meet working-capital and other needs for at least 12 months. Dividend and repurchase plans remain discretionary.
Key risks include renewed COVID-19 disruptions, semiconductor supply constraints, volatile customer orders, competition and pricing pressure, customer and distributor concentration, and exposure to Asian markets. Wafer-supplier pricing is partly affected by yen-dollar movements; management estimated a 10% currency change could correspond to about a 1.0% change in gross margin, all else equal.
Two Opticurrent patent cases remain unresolved. A prior jury award was reduced to $1.2m and is under appeal; a second case is pending. CogniPower litigation is also ongoing, with related proceedings stayed pending patent-review proceedings. The company cannot estimate a loss or range for the unsettled litigation. H1’s 4.9% effective tax rate was favorably affected by a discrete release of an unrecognized tax benefit, as well as geographic earnings mix, research credits, and share-based payment tax benefits.
Important facts for investors to verify
- Whether exceptional revenue growth and customer demand persist, particularly given distributor and end-customer concentration.
- How end-market mix, manufacturing efficiency, wafer availability, and currency movements affect gross margin.
- The outcomes and potential financial or operational consequences of the Opticurrent and CogniPower matters; the company has not estimated potential litigation losses.
- Whether the unusually low effective tax rate and elevated earnings growth are sustainable; H1 tax included a favorable discrete item.
- Execution and cash requirements for planned investment, dividends, and repurchases; the filing reports no formal quantified financial guidance.
