Research and development expense increased to $20.1 million from $17.2 million, while sales and marketing expense increased to $6.6 million from $6.2 million and general and administrative expense increased to $4.6 million from $4.1 million. Financial income of $1.0 million in 2020 became net financial expense of $0.2 million in 2021, primarily because of lower investment income and foreign-exchange losses.
At December 31, 2021, total assets were $219.6 million, total liabilities were $61.1 million and shareholders’ equity was $158.5 million. Cash and cash equivalents were $29.3 million. Held-to-maturity corporate and government debt securities totaled $32.3 million at amortized cost, including $8.3 million current and $24.0 million non-current. The company reported no short- or long-term interest-bearing loans or debt.
Working capital was $98.8 million and the current ratio was 2.96. Trade receivables increased to $31.1 million from $21.7 million, while inventories increased substantially to $75.8 million from $47.7 million. Trade payables increased to $29.9 million from $14.6 million.
Capital expenditures were approximately $2.5 million, and investment in intangible assets was $3.6 million. Internally developed software capitalized during 2021 contributed to net intangible assets of $4.3 million at year-end; total capitalized internally developed software costs were approximately $6.5 million before accumulated amortization.
Material changes versus the prior comparable period
- Sales growth was driven mainly by continued demand for Smart Edge products, particularly SD-WAN, and initial penetration into 5G/O-RAN markets, partially constrained by global component shortages.
- Gross margin improved to 34.6%, partly because 2020 included a one-time $1.7 million intangible-asset impairment and because of product mix. However, inventory write-downs increased to $5.2 million, or 4.1% of sales, compared with $1.6 million, or 1.5% of sales, in 2020.
- Operating income and net income improved materially, despite higher operating expenses and increased research and development investment.
- Operating cash flow declined to $1.1 million, primarily because inventory increased by $33.5 million, partially offset by higher trade payables.
- The company repurchased approximately $14.3 million of ordinary shares in 2021. Treasury shares increased to 960,505 shares at year-end, and outstanding shares declined from 6,899,515 to 6,709,528.
- The dividend policy, which contemplated distributions of up to 50% of annual distributable profits, remained suspended since March 2018.
Guidance, outlook, commentary, risks and unusual items
Management did not provide a specific quantitative 2022 revenue or earnings forecast in the filing. Management expects continued investment in research and development and views cloud adoption, disaggregation, decoupling, SD-WAN, NFV and O-RAN/5G as important long-term opportunities. The filing states that cash resources are sufficient to fund operating needs for at least the next twelve months.
Subsequent disclosures included additional 2022 design wins involving edge networking and SD-WAN platforms, and a major design win from a U.S. communications service provider. These announcements do not constitute quantified revenue guidance.
- Global component shortages, long supplier lead times, price volatility and dependence on limited or single sources, including Intel and Broadcom components, could constrain production, margins and delivery schedules.
- Inventory risk is significant: inventory rose sharply to support rapid delivery requirements, while customer orders generally have short lead times and are not long-term purchase commitments. Forecast errors or canceled design wins could result in excess inventory and write-offs.
- Design wins have lengthy qualification and sales cycles and may not convert into sustained revenue. The company is dependent on a small number of customers; its top four ultimate customers represented approximately 35% of 2021 revenue and its largest customer approximately 15%.
- Rapid technology changes, competitive pricing, customer adoption of alternative solutions and the integration of functionality into standard servers could reduce demand or gross margins.
- COVID-19-related disruptions, the war in Ukraine, sanctions, trade restrictions involving China, and broader economic weakness could affect supply chains, customer deployments and sales.
- Israeli political and security conditions, employee military reserve duty, foreign-exchange movements in the Israeli shekel and Danish krone, export-license requirements and changes to Israeli tax benefits create additional risks.
- The company held approximately $32.0 million of corporate and government debt securities. Unrealized losses at year-end were $0.5 million, but no credit-related carrying-value adjustment was required.
- Contingent IIA royalty obligations were approximately $3.0 million at year-end, relating to discontinued products. The company stated that all IIA programs had been closed and that it did not anticipate sales requiring additional royalties.
- Approximately $56.1 million of retained earnings were tax-exempt under prior Israeli programs. Distribution of this income could create an estimated additional corporate tax liability of up to approximately $14.0 million.
- No material litigation was pending or threatened according to the filing. The auditors issued unqualified opinions, and management and the auditors concluded that internal control over financial reporting was effective as of December 31, 2021.
Most important facts for investors to verify
- Whether the strong 2021 sales and margin improvement continued after year-end, particularly in Smart Edge, SD-WAN, 5G and O-RAN products.
- Whether the substantial inventory build can be converted into sales without additional material write-downs.
- Customer concentration, renewal and deployment status of major design wins, and the timing of revenue realization from those wins.
- Current operating cash flow and working-capital requirements, including receivables collection and supplier-payment trends.
- Exposure to component shortages, supplier concentration, freight and input-cost inflation, and related gross-margin pressure.
- The company’s cash, marketable-securities portfolio, share-repurchase activity and absence of interest-bearing debt.
- Eligibility for Israeli preferred technological enterprise tax benefits and the potential tax cost of distributing tax-exempt retained earnings.
- Any financial or operational effects from COVID-19, the Ukraine conflict, sanctions, export controls or Israeli geopolitical developments.
