Material changes versus the prior comparable period
- Revenue declined 3.5%. IoT revenue rose 5.2% to $488.2 million, while Infrastructure fell 8.2% to $183.2 million, Broadcast fell 18.7% to $114.9 million, and Access fell 19.2% to $51.3 million.
- Unit volumes declined 3.8%; average selling prices increased 0.2%. Gross margin improved 0.8 percentage points, primarily because fiscal 2018 included a $6.1 million acquired-inventory fair-value charge.
- Operating expenses rose to $453.6 million from $436.2 million, mainly due to higher R&D and personnel costs. R&D was $257.2 million, or 30.7% of revenue.
- Net income fell substantially, largely reflecting the $30.4 million income-tax provision in 2019 versus an $11.4 million tax benefit in 2018. A $27.2 million discrete tax expense followed the Ninth Circuit’s reversal in the Altera stock-based-compensation cost-sharing case.
- Operating cash flow was down $7.0 million year over year. The company repurchased 0.3 million shares for $26.7 million in fiscal 2019.
Outlook, commentary, risks and unusual items
For fiscal 2020 Q1, management forecast revenue of $209–$219 million, gross margin of 59.5%, operating expenses of $127 million, an effective tax rate of 0.0%, and diluted EPS of $(0.03)–$0.07. Management expected R&D and SG&A to increase in absolute dollars versus fiscal 2019 Q4. Fiscal 2020 includes an extra week; the filing does not provide full-year revenue or earnings guidance.
- Management described semiconductor-market weakness amid macroeconomic uncertainty, elevated customer inventories and trade tensions, particularly involving China.
- Key exposures include dependence on distributors (73% of fiscal 2019 revenue), with Arrow Electronics at 26% and Edom Technology at 20%; concentration in Asian manufacturing and testing; and the absence of binding long-term customer purchase commitments.
- The company cited product-demand and pricing volatility, competition, inventory and yield risks, evolving IoT standards, cybersecurity and IP litigation risks, and potential disruption from geopolitical events or natural disasters.
- The company is appealing a Norwegian tax assessment related to intercompany pricing that could involve approximately $16 million of additional tax. Management believes its position is more likely than not to be sustained; an adverse outcome could materially affect results.
- About $6.0 million par value of auction-rate securities remained illiquid after failed auctions; the securities have a contractual maturity in 2046. The company reported no material off-balance-sheet arrangements.
- A material weakness in controls over business-combination accounting identified at fiscal 2018 year-end was reported as remediated. Management and the auditor concluded internal control over financial reporting was effective at December 28, 2019; the financial-statement audit opinion was unqualified.
Important facts for investors to verify
- Confirm the applicable period: this is fiscal 2019, with Q4 2019 data, rather than 2018 Q4.
- Assess whether IoT growth can offset continuing declines in Broadcast, Access and Infrastructure, and whether margins hold as product mix and pricing change.
- Review the tax impact and any subsequent developments in the Altera matter and the Norwegian tax appeal.
- Track distributor exposure, customer inventory, order trends, and manufacturing and test capacity concentration in Asia.
- Review the $400 million convertible-note maturity and terms, available revolver capacity, and the remaining authorization under the share-repurchase program.
