Material changes and drivers
- Revenue increased $43.4 million, mainly from communications sales—particularly InnoSwitch products in mobile-device chargers—and consumer appliances. Lower computer-market unit sales partly offset growth.
- End-market mix shifted toward lower-margin communications products: communications rose to 27% of revenue from 24%; industrial declined to 31% from 33%. Management attributed the annual gross-margin decline primarily to mix. CamSemi-related amortization and inventory fair-value charges had also weighed on 2015 margin.
- Operating expenses rose to $143.3 million from $134.4 million, including higher performance-based stock compensation and product-development headcount. Stock-based compensation expense increased to $20.9 million from $14.8 million.
- Revenue from outside the United States was approximately 96% of total. Avnet represented 18% of revenue and Powertech Distribution 11%; the top ten customers collectively represented 60%.
Outlook, risks and unusual items
- Management stated that operating cash flow and existing liquidity should meet projected working-capital and other cash requirements for at least the next 12 months, and expected continued sales growth in its foreign business. The filing provides no specific FY 2017 revenue or earnings guidance.
- Key risks include short-term, cancellable customer orders; distributor concentration and limited end-customer visibility; intense price competition; dependence on three wafer foundries and outsourced assembly; and foreign-exchange exposure. Management estimated that a 10% U.S. dollar move against the yen could change gross margin by about 1.0%, all else equal.
- Patent litigation is significant and outcomes remain uncertain. The company reported a $139.8 million jury damages verdict against Fairchild, but stated it could not predict recovery and had recorded no benefit. Appeals and other proceedings continue; ON Semiconductor and the company have also filed patent actions against each other. Management could not estimate a loss or range of loss for unsettled litigation.
- The effective tax rate was 2.1% in 2016, reflecting earnings in lower-tax jurisdictions and the federal R&D tax credit. Unrecognized tax benefits were $15.4 million. Approximately $265.0 million of foreign earnings were considered indefinitely reinvested outside the United States.
- The company planned to early-adopt the new revenue standard on January 1, 2017, using full retrospective presentation. It expected distributor revenue recognition to shift from sell-through to sell-in; its analysis indicated annual revenue would have been about $2 million higher in 2016 and $1 million higher in 2015 under the new method. The filing also anticipated a $7–$8 million windfall tax benefit upon adoption of the amended stock-compensation standard.
- Dividends were $0.13 per share quarterly in 2016; in January 2017 the board declared $0.14 quarterly dividends for 2017. The board authorized $23.6 million of remaining share-repurchase capacity at year-end.
Most important facts for investors to verify
- Whether revenue growth, especially InnoSwitch-related communications sales, continues without further pressure on gross margin.
- Distributor inventory, sell-through, ship-and-debit claims and the effect of the 2017 sell-in revenue-accounting transition on reported quarterly trends.
- Wafer supply capacity and renewal/continuity of supplier agreements, particularly the Lapis agreement expiring in April 2018.
- Developments, potential costs and outcomes in the Fairchild/ON Semiconductor and other patent proceedings; no litigation gain was included in reported results.
- Tax exposure and the assumptions supporting indefinite reinvestment of foreign earnings, alongside the impact of accounting-standard adoption.
