Material changes versus the prior comparable period
- Sales increased 46.9% year over year. Management attributed 25.5 percentage points to organic growth and 21.4 points to the LSC acquisition, completed in November 2020.
- Gross profit rose 55.5% and gross margin improved 200 basis points. Management cited favorable product mix, higher-margin market growth and increased utilization at LSC facilities, despite supply constraints.
- Operating expenses rose 32.9%, including a full year of LSC-related expenses versus one month in 2020; however, operating expenses declined as a share of sales.
- Average selling prices increased 9.5%, reflecting product mix and price increases; average unit costs rose 6.0%, partly from subcontractor and foundry costs and a more premium product mix.
- Automotive revenue grew more than 59% year over year. Computing increased to 30% of sales from 20%; communications fell to 16% from 21%, and consumer to 19% from 25%.
- Operating cash flow increased to $338.5 million. Investing used $144.2 million, mainly for capital spending; financing used $158.4 million, primarily from net debt reduction. Cash, including restricted cash, increased by $46.3 million.
Outlook, risks and unusual items
- Management reiterated 2025 targets of $2.5 billion in revenue, $1.0 billion in gross profit and a 40% gross margin. These are strategic targets, not near-term guidance. Management described the long-term outlook as generally favorable while noting economic uncertainty and supply constraints.
- Key execution risks include semiconductor cyclicality, order cancellations or deferrals, pricing pressure, supply availability, manufacturing disruption, customer qualification requirements and integration of acquisitions. The company’s manufacturing footprint and sales are significantly exposed to Asia and China.
- 2021 included a $28.0 million unrealized investment gain and a $9.5 million gain on the sale of a Chinese manufacturing subsidiary, recorded in other income. These items contributed to reported results; the filing does not quantify their combined after-tax effect on earnings per share.
- The effective income tax rate increased to 25.0% from 17.5%. The filing cites higher pre-tax income and changes to certain foreign-subsidiary outside-basis differences.
- The U.K. defined-benefit pension plan was underfunded by $11.7 million at year-end. The next triennial funding review was scheduled for March 2022.
- Capital commitments included $96.4 million of non-cancelable equipment purchases and approximately $239.2 million of wafer purchases scheduled for 2022–2025. The company was negotiating a replacement agreement with the Chengdu development zone after its prior agreement expired.
- Management said pending legal proceedings were not expected to have a material adverse effect; no material litigation was identified. The independent auditor opined that the financial statements were fairly presented and internal control over financial reporting was effective.
Important facts for investors to verify
- How much 2021 earnings and margin improvement is sustainable after separating organic growth, LSC contribution, pricing and product-mix effects.
- The recurring versus nonrecurring contribution to earnings from investment gains and the manufacturing-subsidiary sale.
- Whether supply constraints, higher input costs and customer order flexibility affect future production, backlog conversion and margins; reported backlog was $793.1 million, but orders are generally cancellable or modifiable without penalty.
- Debt maturity, floating-rate exposure and covenant headroom; management estimated a 1 percentage-point rate change would alter annual interest expense by about $2.9 million.
- Progress toward the 2025 targets, planned capital spending and capacity utilization, including the status of the Chengdu agreement.
- Tax exposures and the potential impact of foreign withholding taxes; the company disclosed $43.4 million of unrecognized tax benefits.
