Material changes versus prior period
- FY revenue increased 21.2%. Unit shipments rose 9% and average selling prices increased 12%. Growth came from all end markets except communications; automotive revenue rose 58.7% and computing and storage rose 25.1%.
- Gross margin improved 0.5 percentage points to 54.8%, while operating margin rose 2.4 points to 16.4%. R&D and SG&A increased in dollars, but each declined as a share of revenue.
- Operating cash flow increased by $26.0 million. Investing outflows rose, principally reflecting $65.8 million of property and equipment purchases and net purchases of short-term investments; cash declined by $29.9 million overall.
- Net income increased 23.7%, but the effective tax rate rose to 21.4% from 7.9%, reflecting the 2017 Tax Act and other tax items.
- Communications revenue fell 1.7% to $63.6 million. The largest distributor’s share of revenue declined to 17% from 22%.
Outlook, risks and unusual items
- Management described plans to expand existing product families and enter new product categories and markets; it provided no quantified FY 2018 revenue or earnings guidance in the supplied filing text.
- Management said available cash, cash equivalents, short-term investments and operating cash generation should cover liquidity needs for the next 12 months. The board increased the quarterly dividend from $0.20 to $0.30 per share effective Q1 2018. The 2016 share-repurchase program expired at year-end 2017 with its $50 million authorization unused.
- The 2017 Tax Act produced provisional tax accounting: $41.9 million of transition-tax expense, offset by $18.0 million of R&D tax credits, leaving $23.9 million payable over eight years. A $9.8 million deferred-tax remeasurement charge and a $21.6 million federal valuation-allowance release also affected the tax provision. The company said its tax accounting was incomplete and estimates could change materially.
- Key exposures include customer and distributor concentration, heavy reliance on Asia, cyclical demand, supplier wafer capacity and yields, inventory forecasting, competitive pricing, and intellectual-property litigation. Inventory increased to $99.3 million from $71.5 million; management cited strategic wafer and die inventory and finished goods for demand and growth.
- FY 2017 litigation expense was $1.2 million, primarily related to ongoing litigation; the company reported no material pending legal proceedings at December 31, 2017. It held $5.3 million of illiquid student-loan auction-rate securities. Stock-based compensation was $52.6 million.
