Liquidity, capital structure and balance sheet
- Cash and cash equivalents were $17.021 million, compared with $11.917 million at December 31, 2016.
- Held-to-maturity marketable securities totaled approximately $13.7 million at year-end, consisting of corporate debt securities; no other-than-temporary impairment was recorded.
- Working capital was $104.401 million and the current ratio was 6.48.
- Total assets increased to $162.614 million from $146.437 million; shareholders’ equity increased to $140.800 million from $121.392 million.
- Trade receivables increased to $41.367 million from $27.722 million, and inventories increased to $51.487 million from $44.280 million.
- The company reported no short- or long-term interest-bearing debt. Long-term liabilities consisted primarily of $2.765 million in employee severance obligations at year-end.

- Contractual obligations totaled $26.157 million, including $23.055 million of purchase obligations and $3.102 million of operating leases.
Material changes versus 2016
- Sales growth was driven primarily by target markets associated with cloud computing, cyber security, SDN, NFV, virtualization and SD-WAN, as well as expansion of the customer base and product portfolio.
- Gross margin declined because of product mix and the company’s strategic decision to pursue additional cloud-related revenue opportunities. Inventory write-downs declined to 2.3% of sales from 3.2%.
- Research and development expense increased 9.9% to $13.915 million, reflecting additional development personnel, currency effects and continued investment in new products.
- Sales and marketing expense increased 4.7% to $6.722 million, and general and administrative expense increased 13.6% to $4.507 million.
- Operating cash flow returned to positive territory, but cash conversion remained affected by higher receivables and inventory. Inventory increased by $7.207 million and trade receivables increased by $13.645 million.
- Sales concentration remained significant: the top two customers represented approximately 34% of 2017 revenue, while the top four represented approximately 48%. Three customers represented approximately 62% of accounts receivable at year-end.
Outlook, commentary, risks and unusual items
Management identifies cloud infrastructure, data centers, virtualization, SDN, NFV, SD-WAN, cyber security and edge networking as key growth opportunities. The company expects to continue investing in research and development and to finance capital expenditures from internal resources. It stated that available cash resources were sufficient for present requirements and expected operating needs for at least the next twelve months.
The filing does not provide formal revenue or earnings guidance. Management cautions that long design-win sales cycles, short customer order lead times, changing technology, customer concentration and dependence on purchase orders make quarterly and annual revenue difficult to forecast.
Significant subsequent event: In March 2018, the top-tier cloud customer associated with Silicom’s largest-ever design win decided to abandon the new cloud infrastructure architecture for which it had ordered Silicom products. The customer stated that the decision was related to changes in its technical and business strategy, not Silicom’s product, development or support. At the announcement date, approximately $10 million of related receivables remained outstanding. Management expected collection, but the cancellation could result in excess inventory, inventory write-offs, operational costs, disputes with customers or suppliers, lower future revenue and reduced cloud-market growth.
On March 15, 2018, the board suspended the dividend policy until further notice to retain funds for long-term growth. The company had paid a $1.00-per-share dividend for 2016 in April 2017.
Other key risks include reliance on a limited number of customers and component suppliers, potential technology obsolescence, competitive pricing pressure, foreign-exchange exposure to the Israeli shekel and Danish krone, Israeli political and security conditions, export-license requirements, tax-benefit eligibility, IIA/OCS restrictions on funded technology and manufacturing, and possible PFIC treatment for U.S. shareholders. The company disclosed approximately $2.960 million of potential OCS/IIA royalty contingencies related to discontinued products, although it did not expect further related sales.
Management and the independent auditor concluded that disclosure controls and internal control over financial reporting were effective as of December 31, 2017. The auditor issued an unqualified opinion.
Investor verification points
- Verify the financial impact of the cancelled cloud design win, including inventory exposure, receivables collection, purchase-order commitments, potential write-offs and any subsequent customer or supplier disputes.
- Reconcile the reported $4.642 million contingent-consideration benefit to acquisition agreements and assess the effect of excluding this non-recurring benefit from underlying profitability.
- Monitor gross-margin trends as cloud and telecommunications revenue expands and confirm whether lower-margin business is diluting profitability.
- Assess working-capital requirements, particularly the growth in inventories and accounts receivable relative to sales and operating cash flow.
- Evaluate customer concentration, including the largest customers’ revenue, receivables and design-win deployment schedules.
- Confirm the status of the suspended dividend policy and the company’s intended allocation of retained cash.
- Review exposure to component shortages, technology transitions, currency movements and Israeli tax or IIA/OCS obligations.
