Quarterly results, outlook and commentary
Fourth-quarter FY 2016 revenue was $182.6 million, gross margin $109.5 million (about 59.9%), operating income $20.1 million and net income $20.1 million; diluted EPS was $0.47. Fourth-quarter FY 2015 revenue was $160.1 million, gross margin $93.5 million, operating income $4.8 million, net income $5.7 million and diluted EPS $0.13.
Management forecast first-quarter FY 2017 revenue of $174 million to $179 million and diluted EPS of $0.21 to $0.27. It expected R&D expense to rise in absolute dollars and SG&A to remain relatively stable. Planned FY 2017 capital expenditures were approximately $18 million to $22 million. Management stated that existing cash, investments and available credit were expected to cover requirements for at least 12 months.
Risks, contingencies and unusual items
- Key exposures include semiconductor cyclicality, pricing pressure, product obsolescence, customer order variability, lengthy design-win and qualification cycles, and dependence on a limited number of foundries and Asian assembly and test providers.
- Distributors accounted for 68% of FY 2016 revenue; Edom Technology, Avnet and Arrow Electronics represented 17%, 13% and 11%, respectively. No end customer exceeded 10% of revenue. International sales were 86% of revenue.
- Patent litigation involving television tuners remained unresolved in part: several claims were found invalid or unpatentable, but an appeal concerning a subset of claims was pending. The company had not accrued a material liability and could not predict the outcome or financial impact.
- Tax results warrant attention: FY 2016 included a $33.1 million benefit recognized in connection with the Altera tax matter, while a $31.2 million deferred tax liability was accrued for potential U.S. tax on associated foreign earnings. The IRS had appealed the tax decision.
- The company expects adoption of the new revenue standard to accelerate recognition of distributor sales; it anticipated modified-retrospective adoption and was still evaluating the financial-statement effect.
- On January 20, 2017, the company acquired Zentri for initial cash consideration of $15.5 million, adjusted for specified items, plus up to approximately $10.0 million of potential revenue-based consideration.
- Other principal risks include cyberattacks, intellectual-property claims, inventory exposure, foreign currency and geopolitical risks, and potential disruption at suppliers or customers. No significant off-balance-sheet arrangements were reported.
Most important facts for investors to verify
- Whether IoT and infrastructure growth can continue to offset declines in access and broadcast, particularly as selling prices fall.
- The quality and sustainability of earnings, including the low effective tax rate, Altera-related tax benefit, and Singapore tax incentives.
- Cash availability and valuation risk for auction-rate securities, and debt repayment and credit-facility terms.
- Distributor concentration, channel inventory and the expected impact of the new revenue-recognition standard.
- Developments in the patent dispute and any resulting indemnification, legal-cost or business impacts.
- Integration and performance of Micrium and Zentri, and the company’s ability to realize value from acquisitions and new products.
