Fourth-quarter revenue was $201.0 million versus $182.6 million in the prior-year quarter; operating income was $26.4 million versus $20.1 million. The company reported a Q4 net loss of $4.9 million, or $0.11 per diluted share, compared with net income of $20.1 million, or $0.47 per diluted share, a year earlier.
At year-end, cash, cash equivalents, and short-term investments totaled $764.0 million; working capital was $785.3 million. Operating cash flow was $189.5 million. Accounts receivable was $71.4 million (32 days sales outstanding), and inventory was $73.1 million (81 days of inventory). The company had $400 million principal amount of convertible notes, with a $341.9 million balance-sheet carrying amount, and no borrowings under its revolving credit facility. Total assets were $1.535 billion and total liabilities were $582.1 million.
Material changes versus comparable periods
- Annual revenue and operating income increased, led by IoT growth; broadcast and access revenue declined.
- Net income fell despite higher operating income, principally reflecting a higher tax provision and increased interest expense. The effective tax rate was 38.8%, versus 4.7% in 2016.
- The Tax Cuts and Jobs Act produced a reported $26.3 million net tax expense, including a provisional $54.4 million transition-tax expense and $21.8 million expense from deferred-tax revaluation, partly offset by tax benefits.
- Cash and short-term investments rose from $300.3 million to $764.0 million. The company issued $400 million of convertible notes and used $72.5 million to repay its credit-agreement balance.
- Operating cash flow increased from $128.9 million to $189.5 million. Investing cash outflow increased to $374.3 million, mainly due to purchases of marketable securities and acquisitions.
Outlook, risks, and unusual items
For fiscal 2018 Q1, management forecast revenue of $196–$202 million, gross margin of 59.0%, operating expenses of approximately $98 million, an effective tax rate of negative 15.0%, and diluted EPS of $0.42–$0.48. The company expected R&D and SG&A expense to increase in absolute dollars in Q1, and forecast fiscal 2018 capital expenditures of $28–$32 million. Management stated that existing liquidity and available credit should cover requirements for at least 12 months.
- Tax uncertainty: Tax Act accounting remained provisional, including analysis of GILTI and foreign-subsidiary tax positions. Separately, Norwegian authorities assessed an adjustment that could result in approximately $30 million of additional tax, excluding interest and penalties. The company disputes the assessment and said it might be asked to pay approximately $15 million during 2018 while appealing.
- Acquisitions: The proposed Sigma Designs transaction shifted to a planned $240 million Z-Wave asset purchase, subject to shareholder approval. Integration, closing, and realization of expected benefits remain uncertain. Zentri was acquired in January 2017.
- Litigation: Patent proceedings involving Cresta Technology successors remained unresolved; the company said it could not predict the outcome or financial impact.
- Operating risks: The company cited semiconductor cyclicality, price erosion, product acceptance and design-win timing, distributor and customer concentration, inventory exposure, and dependence on Asian foundries and subcontractors. Three distributors accounted for 45% of 2017 revenue; no end customer exceeded 10%.
- Other liquidity considerations: $6.0 million par value of auction-rate securities remained illiquid, with failed auctions and contractual maturity in 2046. The company had no significant off-balance-sheet arrangements and reported effective internal controls and an unqualified audit opinion.
Important facts for investors to verify
- Confirm the filing period: this is FY 2017, with Q4 results included, rather than a 2016 Q4 filing.
- Review the drivers and durability of IoT growth, ASP declines, and margin pressure, alongside continued weakness in access and broadcast markets.
- Assess the cash and earnings effects of tax reform, the Norwegian tax dispute, and the company’s stated Q1 tax-rate outlook.
- Check the final approval, purchase terms, and integration outcomes for the Z-Wave transaction.
- Evaluate the convertible notes’ cash-settlement plan, dilution exposure, and the company’s ability to maintain liquidity while funding acquisitions and repurchases.
