increases or decreases in customer orders for our products and services, market, financial or other factors that may delay or materially impact customer purchasing decisions, non-availability of products due to supply chain challenges, including component and labor shortages and increasing lead times as well as disruptions as a result of the COVID-19 pandemic, contractual terms with customers that result in delayed revenue recognition and varying budget cycles and seasonal buying patterns of our customers.

More specifically, our customers tend to spend less in the first quarter as they are finalizing their annual budgets, and in certain regions, customers are challenged by winter weather conditions that inhibit fiber deployment in outside infrastructure.

More specifically, our customers have in the past spent less in the first quarter as they are finalizing their annual budgets, and in certain regions, customers are challenged by winter weather conditions that inhibit fiber deployment in outside infrastructure.

Our revenue is also dependent upon our customers’ timing of purchases, capital expenditure plans and decisions to upgrade their network or adopt new technologies, including adoption of our software and cloud platform solutions, as well as our ability to grow our customer base.

Cost of revenue is strongly correlated to revenue and tends to fluctuate due to all of the above factors that may cause revenue fluctuations.

Factors that impacted our cost of revenue for the three and nine months ended October 2, 2021, and that we expect will impact cost of revenue in future periods, also include:

changes in the mix of products delivered, customer location and regional mix, changes in the cost of our inventory, including higher costs due to materials shortages including components, supply constraints or unfavorable changes in trade policies, investments to support expansion of cloud and customer support offerings as well as our customer success organization, changes in product warranty and incurrence of retrofit costs, amortization of intangibles, asset write-offs, support fees for silicon-related development work for our products and inventory write-downs.

Given the ongoing supply chain disruptions related to component shortages, longer lead times as a result of increased global demand for certain components and disruptions and related to the COVID-19 pandemic, we see continued product supply delays and related challenges, which we expect to persist in the foreseeable future.

Similarly, challenges in

supply chain logistics have persisted due to greater global demand for transport services as well as labor shortages and resulted in increases in our global freight charges as we have elected to ship by air in order to meet delivery commitments to our customers and as air freight rates have increased from prior year levels.

Factors that have impacted our cost of revenue for the three months ended April 2, 2022, and that we expect will impact cost of revenue in future periods, also include:

Given the ongoing supply chain disruptions related to component shortages, longer lead times as a result of increased global demand for certain components and disruptions related to the COVID-19 pandemic, we have experienced and are continuing to experience product supply delays and related challenges, and we expect these delays

and related challenges to persist in the foreseeable future.

Similarly, challenges in supply chain logistics have persisted due to greater global demand for transport services as well as labor shortages and resulted in increases in our global freight charges.

In addition, we periodically elect to ship by air in order to meet delivery commitments to our customers, and air freight rates remain elevated relative to pre-pandemic levels.

Cost of revenue also includes fixed expenses related to our internal operations, which could increase our cost of revenue as a percentage of revenue if our revenue declines.

Our gross profit and gross margin fluctuate based on timing of factors such as changes in customer mix and changes in the mix of products demanded and sold (and any related write-downs of existing inventory) and have in the past been negatively impacted by increases in mix of revenue from channel sales rather than direct sales or other unfavorable customer or product mix, shipment volumes and any related volume discounts, changes in our product and services costs, pricing decreases or discounts, new product introductions or upgrades to existing products, customer rebates and incentive programs due to competitive pressure or materials shortages, supply constraints, investments to support expansion of cloud and customer support offerings, tariffs or unfavorable changes in trade policies.

and fluctuations in stock-based compensation expenses due to timing of equity grants or other factors affecting vesting.

During the third quarter of 2021, we recognized a discrete tax benefit of $162.0 million based on our reassessment of the amount of our U.S.

federal and state deferred tax assets that are more likely than not to be realized, primarily as a result of actual and projected increases in U.S.

profitability in the current and future periods.

Further, as a result of factors contributing to the fluctuations described above among other factors, many of which are outside our control, our quarterly operating results fluctuate from period to period.

In July 2021, we reopened our U.S.

offices to fully-vaccinated employees, who choose to work in the office, and visitors as well as lifted certain travel restrictions.

The spread of COVID-19 has had a prolonged impact on our supply chain operations due to restrictions, reduced capacity and limited availability from suppliers on whom we rely for sourcing components and materials and from third-party partners on whom we rely for manufacturing, warehousing and logistics services.

Although demand for our products has been strong in the short-term as subscribers seek more bandwidth and better Wi-Fi, customers’ purchasing decisions over the long-term may be impacted by the pandemic and its impact on the economy, which could in turn impact our revenue and results of operations.

Our management evaluates its estimates, assumptions and judgments on an ongoing basis.

Our critical accounting policies and estimates, which are revenue recognition and inventory valuation, are described under “Critical Accounting Policies and Estimates” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2020.

During the third quarter of 2021, we recognized an income tax benefit of $ 162.0 million offset by current income taxes, based on our reassessment of the amount of our U.S.

federal and other state deferred tax assets that are more likely than not to be realized, primarily as a result of actual and projected increases in U.S.

profitability in the current and future periods.

As a result, we determined that the following policy is a critical accounting policy and estimate:

We evaluate our tax positions and estimate our current tax exposure along with assessing temporary differences that result from different book to tax treatment of items not currently deductible for tax purposes.

These differences result in deferred tax assets and liabilities on our Consolidated Balance Sheets, which are estimated based upon the difference between the financial statement and tax bases of assets and liabilities using the enacted tax rates that will be in effect when these differences reverse.

In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in our Consolidated Statements of Comprehensive Income become deductible expenses under applicable income tax laws or loss or credit carryforwards are utilized.

Accordingly, realization of our deferred tax assets is dependent on future taxable income against which these deductions, losses and credits can be utilized.

We must assess the likelihood that our deferred tax assets will be recovered from future taxable income, and to the extent we believe that recovery is not more likely than not, we must establish a valuation allowance.

Management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets.

Prior to the third quarter of 2021, we maintained a 100% valuation allowance against all deferred tax assets, because there was insufficient positive evidence to overcome the existing negative evidence, primarily consisting of several years of consecutive reported pre-tax losses, such that it was not more likely than not that the deferred tax assets were realizable.

In the third quarter of 2021, we had reported positive operating performance for five consecutive quarters and continued to maintain a cumulative three-year pre-tax profit.

In addition, we expect continued positive operating performance into the foreseeable future to allow for utilization of all operating loss and substantially all tax credit carryforwards prior to their expiration.

After considering these factors, we determined that the positive evidence overcame any negative evidence and concluded that it was more likely than not that a substantial portion of our U.S.

federal and certain other state deferred tax assets were realizable.

We currently maintain a valuation allowance of $28.7 million for certain U.S.

federal and California state deferred tax assets.

Other than the change above, there have been no significant changes in our critical accounting policies and estimates for the nine months ended October 2, 2021.

Our critical accounting policies and estimates, which are revenue recognition, inventory valuation and supplier purchase commitments and income taxes, are described under “Critical Accounting Policies and Estimates” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2021.

For the three months ended April 2, 2022, there have been no significant changes in our critical accounting policies and estimates.

Our revenue increased by $21.7 million and $131.8 million for the three and nine months ended October 2, 2021, respectively, as compared to the corresponding periods in 2020 mostly due to higher systems revenue of $20.8 million and $128.3 million, as compared to the corresponding periods in 2020.

Services revenue increased by $0.9 million and $3.5 million compared to the corresponding periods in 2020.

The increase in systems revenue was primarily due to higher revenue from our small, regional customers and, to a lesser extent, our medium-sized customers, as service providers adopt our All Platform offerings and seek

to provide a better Wi-Fi experience, partially offset by a decrease in revenue to large customers.

Our revenue increased by $22.9 million for the three months ended April 2, 2022, as compared to the corresponding period in 2021 mostly due to higher systems revenue of $21.1 million, as compared to the corresponding period in 2021.

Services revenue increased by $1.8 million compared to the corresponding period in 2021.

The increase in systems revenue was primarily due to higher revenue from our growing base of small, regional customers as BSPs continue to adopt our All Platform offerings and seek to provide a better Wi-Fi experience for their customers.

The increase in services revenue was due to the continued ramp in our service offerings aligned with cloud and software products for our customers.

For the three and nine months ended October 2, 2021, revenue generated in the United States was $136.3 million and $414.2 million, or 79% and 82% of our total revenue, respectively, compared to $129.2 million and $326.1 million, or 86% and 88% of our total revenue, respectively, for the same periods in 2020.

International revenue was $35.9 million and $88.7 million, or 21% and 18% of our total revenue, respectively, for the three and nine months ended October 2, 2021, as compared to $21.3 million and $45.2 million, or 14% and 12% of our total revenue, respectively, for the same periods in 2020.

One customer represented 10% of our total revenue for the three months ended October 2, 2021.

No customer accounted for more than 10% of our total revenue for the nine months ended October 2, 2021.

Another customer, Lumen Technologies, Inc.

(formerly CenturyLink, Inc.), accounted for more than 10% of our total revenue, representing 12% and 14% of our total revenue for the three and nine months ended September 26, 2020, respectively.

$ 82,738 $ 74,533 $ 8,205 11 % $ 237,621 $ 193,209 $ 44,412 23 %

Our cost of revenue increased by $8.2 million and $44.4 million for the three and nine months ended October 2, 2021, respectively, as compared with the corresponding periods in 2020.

The $7.5 million and $42.4 million increases in our systems cost of revenue were less than the percentage increase in revenue compared with the corresponding periods in 2020.

This was due to continued growth in our All Platform offerings along with favorable customer and product mix, the increasing spread between fixed costs in relation to revenue growth and a refund for previously paid U.S.

import tariffs due to the subsequent export of tariffed products.

This was partially offset by increased costs due to higher prices for transportation and components due to shortages.

The increase in services cost of revenue for the three and nine months ended October 2, 2021 compared with the corresponding periods in 2020 was mainly due to increased personnel costs as we made further investments in our customer success organization.

For the three months ended April 2, 2022, revenue generated in the United States was $165.6 million, or 90% of our total revenue, compared to $139.3 million, or 86% of our total revenue, for the same period in 2021.

International revenue was $19.3 million, or 10% of our total revenue, for the three months ended April 2, 2022, as compared to $22.7 million, or 14% of our total revenue, for the same period in 2021.

Gross profit increased to $89.5 million and $265.4 million for the three and nine months ended October 2, 2021, respectively, from $76.0 million and $178.0 million during the corresponding periods in 2020 due to higher gross margin for both systems and services.

The increase in systems gross margin for the three and nine months ended October 2, 2021 compared to the corresponding periods in 2020 was mainly due to continued growth in our All Platform offerings along with favorable product and customer mix as well as a credit for previously paid tariffs due to product re-export.

This was partially offset by increased costs due to higher prices for transportation and components due to shortages.

Services gross margin increased for the three and nine months ended October 2, 2021 compared to the corresponding periods in 2020 as our service revenue mix shifted away from low gross margin deployment services to higher gross margin services aligned with our platform offerings.

Gross profit increased to $91.8 million for the three months ended April 2, 2022, from $86.2 million during the corresponding period in 2021 due to higher revenue for both systems and services.

The decrease in systems gross margin of 390 basis points for the three months ended April 2, 2022 compared to the corresponding period in 2021 was mainly due to higher component and logistics costs.

Services gross margin increased by 150 basis points for the three months ended April 2, 2022 compared to the corresponding period in 2021 as our service revenue reflects a greater contribution from higher gross margin services aligned with our platform offerings, which more than offset the investments in our customer success organization.

Beginning in the third quarter of 2020, we changed our facility allocation to align with our work-from-anywhere initiative, and consequently, most of our facilities expenses are retained in general and administrative expenses.

These increases were partially offset by a decrease in our bad debt expense of $1.2 million.

We expect our general and administrative expenses to decline as a percentage of revenue over time as revenue continues to grow.

Restructuring Charges

Responding to changes and trends caused by the COVID-19 pandemic, we initiated a restructuring plan in June 2020 to accelerate our All Platform future and to align with a work-from-anywhere culture.

We incurred restructuring charges of $6.3 million, consisting of facilities-related charges and severance and other termination related benefits, for the nine months ended September 26, 2020.

Effective tax rate 17.3 % 0.7 %

During the third quarter of 2021, we recognized an income tax benefit of $162.0 million offset by current income taxes, based on our reassessment of the amount of our U.S.

federal and other state deferred tax assets that are more likely than not to be realized, primarily as a result of actual and projected increases in U.S.

profitability in the current and future periods.

In performing our analysis, we used the most updated plans and estimates that we currently use to manage the underlying business and calculated the ability to utilize our deferred tax assets.

We continue to maintain a valuation allowance of $28.7 million on certain U.S.

federal and California state deferred tax assets that we believe are not more likely than not to be realized in future periods.

As of September 26, 2020, the total expense was primarily related to foreign activity.

In 2020, based on a review of the positive and negative evidence, we concluded that the deferred tax assets were not more likely than not to be realized, which resulted in an immaterial domestic provision as the deferred tax assets were fully offset with the valuation allowance.

Our income taxes may be subject to fluctuation during the year and in future years as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as actual results differing from our estimates of pre-tax earnings in the various jurisdictions in which we operate, which could impact the recognition of our deferred tax assets, the recognition or de-recognition of tax benefits related to uncertain tax positions and changes in or the interpretation of tax laws in jurisdictions where we conduct business.

For the first quarter of 2021, we maintained a full valuation allowance against our deferred tax assets, resulting an income tax provision primarily due to state and foreign taxes payable.

For the first quarter of 2022, after having released the valuation allowance during the third quarter of 2021, our income tax expense was $1.7 million for an effective tax rate of 17.3%, which differs from the statutory rate of 21% primarily due to U.S.

federal research tax credits and excess tax benefits from stock-based compensation partially offset by state taxes, the inclusion of income from certain foreign operations and the effect of non-deductible stock-based compensation for executive officers.

Our income taxes may be subject to fluctuation during the year and in future years as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as actual results differing from our estimates of pre-tax earnings in the various jurisdictions in which we operate, which could impact the recognition of our deferred tax assets, further benefits from stock option exercises, investments in our foreign operations, the recognition or de-recognition of tax benefits related to uncertain tax positions and changes in or the interpretation of tax laws in jurisdictions where we conduct business.

Liquidity and Capital Resources

We have funded our operations and investing activities primarily through sales of our common stock, including an underwritten public offering in August 2020, cash flow generated from operations and various borrowing arrangements.

As of October 2, 2021, we had cash, cash equivalents and marketable securities of $188.7 million, which consisted of deposits held at banks and major financial institutions and highly liquid marketable securities such as U.S.

We have funded our operations and investing activities primarily through sales of our common stock, cash flow generated from operations and various borrowing arrangements.

Operating Activities

Net cash provided by operating activities was $44.2 million for the nine months ended October 2, 2021 and consisted of net income of $218.5 million partially offset by non-cash charges of $132.6 million and cash flow decreases of $41.7 million

reflected in the net change in assets and liabilities.

Non-cash charges consisted of the reversal of the valuation allowance on certain deferred tax assets of $162.0 million offset by stock-based compensation of $18.1 million and depreciation and amortization of $11.4 million.

Cash flow decreases resulting from the net change in assets and liabilities primarily consisted of an increase in inventory of $22.9 million to support revenue growth and to mitigate supply chain shortages and disruptions and an increase in accounts receivable of $22.5 million, due to product shipment timing.

In addition, there was an increase in prepaid expenses and other assets of $9.8 million mainly due to advance payments to our supply chain partners for deposits, expedite fees and component surcharges, capitalized sales commissions and deposits for our ConneXions conference, and a decrease in total accrued liabilities of $11.6 million, mainly related to incentive compensation payouts, rebate redemptions and a reduction of customer advance payments.

These changes were partially offset by an increase in accounts payable of $18.3 million due to increased inventory purchases and an increase in deferred revenue of $6.7 million due to Calix Cloud subscriptions, support contracts and extended warranties.

During the nine months ended September 26, 2020, net cash provided by operating activities was $20.9 million for the nine months ended September 26, 2020 and consisted of $23.9 million of non-cash charges and net income of $9.4 million.

This was partially offset by $12.3 million of cash flow decreases reflected in the net change in assets and liabilities.

Cash flow decreases resulting from the net change in assets and liabilities primarily consisted of an increase in accounts receivable of $22.6 million due to product shipment timing.

In addition, there was increase in inventory of $1.5 million to support higher revenue.

These changes were partially offset by an increase in accounts payable of $5.6 million due to increased inventory purchases, an increase in accrued liabilities of $3.8 million, mainly due to an increase in our liability for components at certain suppliers, and a decrease in prepaid expenses and other assets of $3.7 million, due to amortization of the right-of-use asset.

Cash flow decreases resulting from the net change in assets and liabilities primarily consisted of an increase in inventory of $16.1 million to support revenue growth and to mitigate supply chain shortages and disruptions and an increase in accounts receivable of $2.7 million in line with our revenue growth.

In addition, there was an increase in prepaid expenses and other assets of $6.7 million mainly due to advanced payments to supply chain partners and a decrease in total accrued liabilities of $2.0 million.

These changes were partially offset by an increase in accounts payable of $8.2 million due to increased inventory purchases and an increase in deferred revenue of $4.0 million due to Calix Cloud subscriptions and support contracts.

During the three months ended April 3, 2021, net cash provided by operating activities was $9.9 million and consisted of net income of $20.6 million and non-cash charges of $9.2 million, consisting of stock-based compensation of $5.2 million and depreciation and amortization of $4.1 million.

This was partially offset by cash flow decreases of $20.0 million reflected in the net change in assets and liabilities.

Cash flow decreases resulting from the net change in assets and liabilities primarily consisted of an increase in inventory of $19.9 million to support revenue growth and to mitigate supply chain shortages and disruptions and a decrease in total accrued liabilities of $15.2 million, mainly related to incentive compensation payouts, rebate redemptions and a reduction of customer advance payments.

In addition, there was an increase in accounts receivable of $5.0 million, due to product shipment timing, and an increase in prepaid expenses and other assets of $1.3 million mainly due to prepaid software licenses.

These changes were partially offset by an increase in accounts payable of $16.2 million due to increased inventory purchases and an increase in deferred revenue of $5.4 million due to support contracts, extended warranties and Calix Cloud subscriptions.

The payments are based on a revenue-share rate applied to revenue from the developed product and the corresponding hardware sales through March 2024.
