| Metric | Q1 2021 | Q1 2020 | Change |
|---|---|---|---|
| Revenue | $254.5 million | $165.8 million | +53.5% |
| Gross profit / margin | $141.1 million / 55.4% | $91.4 million / 55.2% | Gross profit +54.3%; margin +0.2 percentage points |
| Operating income / margin | $46.1 million / 18.1% | $31.0 million / 18.7% | Operating income +48.7% |

Revenue growth reflected 28% higher unit shipments and approximately 17% higher average selling prices, primarily from product mix. Revenue rose across all end markets: automotive +92.5%, consumer +77.1%, industrial +57.7%, computing and storage +29.9%, and communications +29.4%. DC-to-DC products generated $241.4 million of revenue; lighting control generated $13.0 million.
Gross margin edged up with favorable product mix, partly offset by higher warranty expense and inventory write-downs. Operating expenses grew faster than revenue: R&D rose 61.4% to $41.9 million and SG&A rose 60.0% to $51.5 million. Stock-based compensation was $28.6 million, up from $18.6 million. The effective tax rate was 6.7%, versus a 22.2% tax benefit in Q1 2020; this difference contributed to net income growing more slowly than operating income.
Liquidity, cash flow, and balance sheet
At March 31, 2021, cash and cash equivalents were $218.4 million and short-term investments were $420.5 million, totaling $638.8 million. Working capital was $734.5 million, up from $695.0 million at December 31, 2020; the current ratio was approximately 4.9. The filing reports no borrowings or outstanding debt balance. Management said existing cash, investments, and operating cash flows should meet liquidity needs for the next 12 months.
Operating cash flow was $77.1 million. Investing activities used $182.9 million, mainly for net purchases of short-term investments and $19.0 million of property and equipment. Financing activities used $11.0 million, including $23.5 million of dividends and dividend equivalents, partly offset by employee equity-plan proceeds. Cash, cash equivalents, and restricted cash declined $116.6 million during the quarter. The company repatriated $70 million from its Bermuda subsidiary and said it may repatriate more.
Total assets were $1.308 billion and total liabilities were $286.6 million. Inventory increased to $175.2 million from $157.1 million at year-end; management attributed the increase mainly to building wafer and die inventories for demand and growth. Purchase commitments totaled approximately $152.2 million. The outstanding one-time transition tax liability was $16.8 million.
Outlook, risks, and unusual items
- The filing provides no quantified revenue or EPS guidance. Management described long-term growth plans centered on new products, new market segments, market-share gains, customer diversification, and securing manufacturing capacity. It expects substantial R&D investment and R&D expenses to increase in absolute dollars in the foreseeable future.
- Management reported no material adverse COVID-19 impact on Q1 results, customer demand, or operations, and no major pandemic-related supply-chain disruption. It cautioned that the pandemic’s duration and future impact remain uncertain.
- Capacity constraints across the semiconductor supply chain may limit growth or increase wafer costs. Orders can be rescheduled or canceled, making forecasting difficult; typical order lead times are 16–26 weeks.
- Geographic and customer concentration are notable: 89% of revenue was from customers in Asia; the two largest distributors represented 26% and 16% of revenue. China accounted for $153.4 million of revenue. The filing highlights China-related regulatory, political, trade, currency, and operating risks.
- Warranty provision was $3.6 million versus $0.5 million a year earlier, and the warranty reserve rose to $9.9 million from $6.9 million at year-end. The filing also cites inventory write-downs as a factor affecting cost of revenue.
- Litigation expense was $1.6 million, down from $2.3 million. The company reported no material pending legal proceedings, while noting ordinary-course disputes and potential legal expenses. No off-balance-sheet arrangements were reported.
- The Board declared dividends of $0.60 per share for the quarter, compared with $0.50 a year earlier. Future dividends remain discretionary and may be reduced or discontinued.
Important facts for investors to verify
- Whether Q1 shipment growth, pricing, and favorable product mix can be sustained, and how margins respond to warranty costs, inventory write-downs, and rising operating expenses.
- Whether suppliers can provide adequate wafer and manufacturing capacity, and whether the $175.2 million inventory balance and $152.2 million purchase commitments remain aligned with end demand.
- Exposure to the two largest distributors, Asia and China, and any changes in customer concentration, trade restrictions, or collection risk.
- The composition, maturity, and liquidity of the $420.5 million short-term investment portfolio, including the Level 3 auction-rate securities.
- Future cash needs for dividends, capital spending, the transition tax, and possible acquisitions; dividend continuation is not assured.
- Potential changes in tax estimates, warranty claims, litigation exposure, and the effects of COVID-19 or industry cyclicality on future results.
