Calix, Inc. — Q3 2021 Form 10-Q
Reporting period: Quarter ended October 2, 2021; comparisons are with the quarter ended September 26, 2020 and the corresponding nine-month periods. Financial amounts below are in U.S. dollars.
Business context and financial performance
Calix provides cloud and software platforms, systems, and services for broadband service providers. Systems revenue includes access and premises systems, platform licenses, and cloud subscriptions; services revenue includes support, maintenance, professional services, training, and managed services.
- Q3 revenue: $172.2 million, up 14% year over year. Systems revenue was $163.1 million (+15%) and services revenue was $9.2 million (+11%). Management attributed systems growth mainly to smaller and medium-sized customers adopting its platform offerings; large-customer revenue declined.
- Nine-month revenue: $503.0 million, up 35%. Systems revenue was $475.9 million (+37%) and services revenue was $27.0 million (+15%). International revenue represented 21% of Q3 revenue and 18% for the nine months, compared with 14% and 12%, respectively, in 2020.
- Gross profit and margins: Q3 gross profit was $89.5 million, with a 52.0% gross margin versus $76.0 million and 50.5% a year earlier. Nine-month gross profit was $265.4 million, with a 52.8% margin versus $178.0 million and 48.0%. Management cited favorable product and customer mix, growth in platform offerings, and a tariff refund; higher transportation and component costs partly offset these gains.
- Operating results: Q3 operating income was $18.0 million versus $21.8 million a year earlier, as operating expenses rose 32% to $71.5 million. Nine-month operating income was $59.3 million versus $12.1 million; 2020 included $6.3 million of restructuring charges. Q3 net income was $177.4 million ($2.61 diluted per share), versus $20.5 million ($0.32); nine-month net income was $218.5 million ($3.24 diluted per share), versus $9.4 million ($0.16).
- Taxes and earnings quality: Net income included a $162.0 million discrete tax benefit from releasing valuation allowances on deferred tax assets, following reassessment of expected future U.S. taxable income. The company retained a $28.7 million valuation allowance. The tax benefit was non-cash and substantially explains the reported net income increase.
- Cash flow: Nine-month operating cash flow was $44.2 million, compared with $20.9 million. The period included significant working-capital investment, including $22.9 million of inventory growth and $22.5 million of higher receivables. Investing cash outflow was $82.8 million, principally net purchases of marketable securities ($75.5 million) and capital expenditures ($7.3 million). Financing cash inflow was $18.0 million, primarily from employee equity plans.
- Liquidity and debt: Cash, cash equivalents, and marketable securities totaled $188.7 million at October 2, 2021, versus $133.8 million at December 31, 2020. Cash and cash equivalents alone were $60.2 million. The company had no borrowings under its $35.0 million revolving credit facility and full borrowing availability; the facility matures in January 2023. Total liabilities were $160.1 million and stockholders’ equity was $535.6 million.
Material changes and management outlook
- Operating expenses increased as Calix invested in sales and marketing, research and development, and general and administrative functions. Stock-based compensation for the first nine months rose to $18.1 million from $9.8 million.
- Inventory increased to $75.2 million from $52.3 million at year-end, partly to support growth and mitigate supply constraints. Accounts payable rose to $31.3 million from $13.1 million.
- Management said it expects to increase sales and marketing investment as a percentage of revenue and slightly increase R&D investment relative to systems gross profit. It expects G&A to decline as a percentage of revenue over time. No specific revenue or earnings guidance was provided.
- Management believes available cash and expected operating cash flows will cover anticipated needs for at least 12 months. It cautioned that failure to execute its plan or sustain operating income and positive cash flows could require additional financing, reduced growth investment, or cost cuts.
Risks, contingencies, and unusual items
- Supply-chain constraints, component shortages, extended lead times, shipping backlogs, and higher freight and component costs were ongoing and expected to persist. Calix relies on third-party manufacturers and suppliers, including limited- or sole-source providers; substantially all silicon suppliers had extended lead times to 52 weeks.
- Outstanding purchase commitments totaled $221.0 million, including approximately $195.9 million due in less than one year. Separately, the company disclosed approximately $184.1 million of supplier inventory purchase commitments expected within one year. Excess and obsolete component inventory liabilities were $4.6 million.
- The company’s revenue-share arrangement for a developed product has aggregate fixed payments of $15.8 million through March 2024; a true-up may be due if minimum payments are not reached. The recorded liability, including accrued interest, was $13.6 million.
- COVID-19 continued to affect supply, logistics, and operations. Management noted strong near-term demand for bandwidth and Wi-Fi products but uncertainty about longer-term customer spending and pandemic effects.
- One customer represented 10% of Q3 revenue; no customer exceeded 10% for the nine-month period. No customer exceeded 10% of receivables. The filing reported no legal proceedings expected by management to have a material adverse effect and no off-balance-sheet arrangements.
- Other disclosed risks include customer spending and adoption of newer platforms, competition and pricing pressure, customer credit and collection risk, cybersecurity and data privacy, international operations, and dependence on government-supported broadband funding.
Most important facts for investors to verify
- How much reported earnings and deferred tax assets depend on the $162.0 million tax benefit, and whether future taxable income supports realization of those assets.
- Whether revenue growth—particularly from smaller and medium-sized customers and platform offerings—can continue, while large-customer revenue has declined.
- Whether component availability, 52-week silicon lead times, logistics costs, and the $221.0 million of purchase commitments affect delivery capacity, margins, or working capital.
- Whether operating cash flow remains positive after excluding the non-cash tax benefit and funding inventory, receivables, and other working-capital needs.
- Progress on expense investment, gross margins, customer concentration, and the company’s $35.0 million credit facility and other contractual obligations.
