Financial position, cash flow and material changes
- Growth and mix: Q3 revenue increased 11.6% year over year; nine-month revenue increased 10.3%. IoT was the principal growth driver: Q3 IoT revenue rose 22.6% to $99.9, and nine-month IoT revenue rose 24.6% to $285.5. Access revenue fell 3.4% in Q3 and 10.0% for nine months. Broadcast and Infrastructure were broadly stable.
- Margins and expenses: Gross margin dollars rose, but gross margin rate fell 2.1 percentage points in Q3 and 1.6 points for nine months, primarily due to product mix. Product unit volumes increased 25.1% in Q3 and 21.7% for nine months, while average selling prices declined 11.1% and 8.8%, respectively. Operating expenses rose year over year in both periods, though as a share of revenue they declined.
- Interest and taxes: Q3 interest expense was $4.8 versus $0.6 a year earlier, reflecting the convertible notes and debt discount/cost amortization. Nine-month interest expense was $9.3 versus $1.9. The nine-month effective tax rate was 2.8%, including a $4.1 tax benefit from adoption of stock-compensation accounting guidance; Q3 effective rate was 9.8%.
- Liquidity: Cash, cash equivalents and short-term investments totaled $718.9 at September 30, 2017, including approximately $543.6 held by U.S. entities. Total current assets were $905.5 and current liabilities $160.0. Management said existing cash, investments and available credit were sufficient for at least 12 months.
- Debt: The company issued $400.0 principal amount of 1.375% convertible senior notes due March 2022 and used $72.5 of proceeds to repay its prior credit-facility balance. The notes’ net carrying value was $338.7; disclosed fair value was $442.6. The $300 revolving facility had no borrowings at quarter-end; the company reported compliance with its covenants.
- Cash flows and investment: Nine-month operating cash flow was $141.4. Investing cash outflow was $354.9, principally reflecting net purchases of marketable securities and the Zentri acquisition. Financing cash inflow was $308.9, largely from net note proceeds. Cash increased to $236.5 from $141.1 at year-end 2016.
- Working capital: Receivables were $76.2, with 35 days sales outstanding. Inventory was $72.9, up from $59.6 at year-end, and represented 80 days of inventory versus 73 days.
Outlook, commentary and risks
- Q4 fiscal 2017 outlook: Revenue of $195–$201; gross margin of 58.5%; operating expenses of approximately $91; effective tax rate of 11.0%; and diluted EPS of $0.40–$0.46. Management expected R&D expense to remain relatively stable and SG&A to decline slightly in absolute dollars.
- Acquisition: Silicon Labs acquired Zentri, a low-power connected-Wi-Fi IoT company, in January 2017 for approximately $18.1, including contingent consideration. The purchase-price allocation was preliminary; goodwill of $12.5 was not tax deductible.
- Tax contingency: Norway’s tax authority proposed an adjustment to the company’s 2013 taxable income that could result in approximately $33 of additional tax, excluding interest and penalties. The company disputes the proposed assessment and intends to contest it; an unfavorable outcome could materially affect its financial statements.
- Other contingencies and unusual items: Cresta patent litigation remains stayed in relevant proceedings; certain patent claims were found invalid, with an appeal pending on one determination. The company said it could not predict the outcome or financial impact. It also held $6.0 par value of illiquid auction-rate securities, with failed auctions and contractual maturity in 2046; management reported no other-than-temporary impairment.
- Principal operating risks: Semiconductor cyclicality, pricing and product-mix pressure, long design and qualification cycles, customer and distributor concentration, dependence on third-party manufacturing capacity, inventory exposure, product-development execution, intellectual-property litigation, cybersecurity, and international/geopolitical disruption. Three distributors each represented more than 10% of nine-month revenue; distributors accounted for 71% of revenue. No individual customer exceeded 10% of revenue.
- Accounting changes: The company expected adoption of the new revenue standard to accelerate distributor revenue recognition, net of estimated price adjustments and return rights. It anticipated using the modified retrospective method. The new lease standard was expected to increase reported assets and liabilities when adopted.
Key facts for investors to verify
- Confirm the reporting-period discrepancy: the filing covers Q3 2017, not Q3 2016 as stated in the request metadata.
- Track whether IoT growth offsets declines in Access and continued average-selling-price erosion, and whether gross margin recovers from the Q3 rate decline.
- Follow the Norwegian tax reassessment, including any final assessment, appeals, interest or penalties, and reserve implications.
- Review convertible-note conversion, cash-settlement capacity, interest expense and potential dilution; also confirm revolving-facility availability and covenant compliance.
- Monitor inventory growth, distributor sell-through and exposure to distributor return and price-protection rights, particularly ahead of the revenue-standard change.
- Assess liquidity quality, including the substantial securities portfolio and the continued illiquidity and valuation assumptions for auction-rate securities.
