SILICON LABORATORIES INC. annual report, FY2022

Business context and reporting period

Silicon Laboratories Inc. (NASDAQ: SLAB) filed this Form 10-K for the fiscal year ended December 31, 2022 (52 weeks), comparing results with fiscal 2021, ended January 1, 2022. The supplied period metadata says “2021 Q4,” but the filing is the FY2022 annual report, not a standalone 2021 Q4 filing. Silicon Labs is a fabless semiconductor company focused on mixed-signal wireless products for the IoT, reported in Industrial & Commercial and Home & Life categories.

Following the July 2021 sale of its infrastructure and automotive business to Skyworks for $2.75 billion in cash, that business is presented as discontinued operations. FY2021 net income therefore includes a large disposal gain and is not directly comparable to FY2022 continuing results.

Financial results and liquidity

• Revenue grew 42.1%; Industrial & Commercial revenue rose 52.0% to $573.7 million, and Home & Life revenue rose 31.1% to $450.4 million.
• Management attributed the gross-margin expansion to higher product prices and product mix. It cautioned that rising inventory costs could pressure future gross margins.
• R&D expense increased to $332.3 million (32.5% of revenue), while SG&A was $191.0 million (18.6% of revenue). Operating expenses totaled $523.3 million.
• At December 31, 2022, cash and cash equivalents were $499.9 million and short-term investments were $692.0 million, totaling about $1.192 billion. The current ratio was about 7.9x, calculated from reported current assets and current liabilities.
• Inventory was $100.4 million, up from $49.3 million; inventory days increased to 90 from 55. Receivables were $71.4 million, down from $98.3 million; DSO improved to 25 from 42 days.
• Debt included $535.0 million principal of 0.625% convertible notes due 2025; net carrying value was $529.6 million. The $400 million revolving credit facility was undrawn, and the company reported covenant compliance.
• FY2022 share repurchases totaled 6.9 million shares for $887.6 million. The company reported 32.0 million shares outstanding at year-end and did not intend to pay cash dividends.

Changes, outlook, and key risks

• Continuing-operations performance improved substantially from FY2021 losses to positive operating income and net income. FY2021’s $2.117 billion net income mainly reflected the discontinued-business sale; it should not be treated as recurring earnings.
• For Q1 FY2023, management forecast revenue of $242–$252 million, gross margin of 63%, operating expenses of $139 million, an effective tax rate of 31%, and diluted EPS of $0.36–$0.46. It expected R&D expense to rise and SG&A to remain relatively stable versus Q4 FY2022.
• Management cited capacity constraints and longer lead times at some suppliers, and expected inventory costs to continue increasing. Major manufacturing, assembly, and test dependencies are concentrated in Asia, including Taiwan; geopolitical disruption, supplier capacity, COVID-related disruption, and logistics are material risks.
• Other disclosed risks include semiconductor cyclicality, inflation and interest rates, customer order cancellations and distributor inventory/price-protection terms, competition and pricing pressure, product development and qualification delays, cybersecurity, and intellectual-property claims.
• A Norwegian tax authority assessment under appeal concerns approximately 141.3 million Norwegian kroner (about $14.3 million) of additional tax; the company believes its position is more likely than not to be sustained but says an unfavorable outcome could materially affect its financial statements. The filing says ordinary-course litigation is not expected to have a material adverse effect; Bell Semiconductor patent actions were resolved in December 2022.
• Auditors issued unqualified opinions on the financial statements and internal control over financial reporting. The critical audit matter was estimation of distributor-related variable consideration for returns and price concessions.

Important facts for investors to verify

1. Confirm that the intended reporting period is FY2022; this filing does not provide standalone 2021 Q4 results.
2. Assess continuing-business growth and margins separately from FY2021 discontinued operations and the Skyworks sale gain.
3. Review Q1 FY2023 guidance against subsequent reported results, particularly revenue, margins, and EPS.
4. Monitor inventory growth and days, supplier capacity and lead times, and the potential effect of higher costs on gross margin and cash conversion.
5. Review the 2025 convertible-note terms, potential share dilution on conversion, cash settlement of principal, and use of capital for substantial repurchases.
6. Track the Norwegian tax appeal, distributor concentration and variable-consideration estimates, and geopolitical exposure to Asian supply-chain operations.
