Unit volume increased 16.9%, while average selling prices decreased 1.9%. Gross margin improved 1.8 percentage points, primarily due to product mix, including greater Infrastructure sales.
Cash, cash equivalents and short-term investments totaled $760.1 million at quarter-end, including $342.3 million in cash and equivalents and $417.9 million in short-term investments. Operating cash flow was lower year over year, with working-capital changes contributing a net outflow. Capital expenditures were $4.1 million in the quarter; management estimated fiscal 2018 capital expenditures of $34–$38 million.
Total liabilities were $565.4 million. Convertible notes had $400 million principal outstanding and a $345.0 million net carrying value; they bear 1.375% coupon interest and mature in 2022. The $300 million revolving facility had no borrowings at quarter-end, and the company reported compliance with its covenants. Management said liquidity and available credit were sufficient for at least 12 months.
Material changes, outlook and commentary
- Operating expenses increased $8.0 million year over year, primarily from higher personnel-related costs. Management expected both R&D and SG&A expenses to rise in Q2, including costs related to increased headcount and the Z-Wave acquisition.
- Q2 fiscal 2018 guidance: revenue of $211–$217 million; gross margin of 58.5%; operating expenses of $111.0 million; effective tax rate of 0.0%; diluted EPS of $0.23–$0.29.
- On April 18, 2018, after quarter-end, the company acquired Sigma Designs’ Z-Wave business for $240 million cash. Z-Wave is an IoT smart-home technology. The purchase price allocation was still under evaluation.
- The company adopted ASC 606 on December 31, 2017 using the modified retrospective method. The $26.2 million cumulative adjustment increased retained earnings. The standard accelerates recognition for qualifying distributor sales; it increased Q1 revenue by $0.7 million and net income by $0.4 million versus the prior accounting treatment. Prior-period figures were not restated.
- A purported class action related to the proposed Z-Wave sale seeks, among other relief, to enjoin the transaction or obtain damages. The company said it could not predict the outcome or financial impact.
- A Norwegian tax authority assessment concerning 2013 intercompany pricing could result in approximately $30 million of additional tax, excluding interest and penalties. The company disputes the assessment and said the authority may request approximately $15 million in 2018 during the appeal process; an unfavorable outcome could materially affect results.
- Some auction-rate securities remain illiquid: $5.6 million fair value, with contractual maturity in 2046. The company said it could not predict when the funds would become available.
Key risks and items to verify
- Track whether Q2 revenue and EPS fall within guidance, and whether the forecast margin reduction from Q1 reflects product mix or other pressures.
- Verify Z-Wave integration, acquisition-related costs and cash impact, and the final purchase price allocation.
- Monitor the Norwegian tax dispute, potential interim payment and any change to tax reserves or reported tax benefits.
- Assess whether working-capital demands, including inventory days rising to 85 from 81 at fiscal year-end, continue to weigh on operating cash flow.
- Review the effects of distributor-channel changes: distributors represented 73% of Q1 revenue, and the company consolidated global distribution to Arrow while retaining regional partners.
- Consider exposure to third-party manufacturing capacity and supply disruptions, product-price erosion, customer and distributor concentration, and semiconductor demand volatility.
- Note the filing reported no repurchases in the quarter under the $100 million repurchase authorization; confirm subsequent activity and remaining authorization.
