Overview
We are a leading global provider of cloud and software platforms, systems and
services for fiber- and copper-based network architectures and a pioneer in
software defined access and cloud products focused on access networks and the
subscriber. Our portfolio allows for a broad range of subscriber services to be
provisioned and delivered over a single unified network. Our access systems can
deliver voice and data services, advanced broadband services, mobile broadband,
as well as high-definition video and online gaming. Our most recent generation
of premises systems enable CSPs to address the complexity of the smart home and
business and offer new services to their device enabled subscribers. We have
designed all of our current platforms and related systems so that they can be
monitored, analyzed, managed and supported by Calix Cloud.
We market our cloud and software platforms, systems and services to CSPs
globally through our direct sales force as well as select resellers. Our
customers range from smaller, regional CSPs to some of the world's largest CSPs.
We have enabled approximately 1,600 customers to deploy passive optical, Active
Ethernet and point-to-point Ethernet fiber access networks.
Beginning in 2018, the United States enacted a series of tariffs on certain
goods manufactured in China. As a result of these tariffs, we incurred U.S.
tariff and tariff-related costs of $6.2 million in 2019 and $1.7 million the
first six months of 2020. In order to mitigate the impact of the tariffs enacted
by the United States, we undertook a broad plan to realign our global supply
chain by moving substantially all of our production outside of China in addition
to other supply chain improvements in the first half of 2019. As a result of the
tariffs imposed on a broader list of products in September 2019, we expanded the
scope of our global supply chain realignment plan, which is expected to take
until the end of 2020 to complete.
Our revenue and potential revenue growth will depend on our ability to sell and
license our cloud and software platforms, systems and services to strategically
aligned customers, including from market segments such as cable MSOs, WISPs,
fiber overbuilders, municipalities and electric cooperatives, in the United
States and internationally.
Revenue fluctuations result from many factors, including, but not limited to:
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 including as a result of uncertainty related to the
COVID-19 pandemic, non-availability of products due to supply chain challenges
including business closures, manufacturing disruptions and component shortages
due to 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. 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 six months ended June 27, 2020,
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 product warranty and incurrence of retrofit costs,
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,
tariffs and associated costs to mitigate the impact of tariffs, amortization of
intangibles, asset write-offs, silicon support fees and inventory write-downs.
In particular, recently we have seen increases in global freight charges
following China's reopening of manufacturing. 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 there are declines in revenue.
Our gross profit and gross margin fluctuate based on timing of factors such as
new product introductions or upgrades to existing products, 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 towards professional services, 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,
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.
Our operating expenses fluctuate based on the following factors among others:
changes in headcount and personnel costs, which comprise a significant portion
of our operating expenses; variable compensation due to fluctuations in shipment
volumes or level of achievement against performance targets; timing of research
and development expenses, including investments in innovative solutions and new
customer segments, prototype builds and outsourced development resources; asset
write-offs; investments in our business and information technology
infrastructure; and fluctuations in stock-based compensation expenses due to
timing of equity grants or other factors affecting vesting.
Our net loss was $11.2 million for the six months ended June 27, 2020 and
$17.7 million for 2019. Since our inception we have incurred significant losses,
and as of June 27, 2020, we had an accumulated deficit of $713.7 million.
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. Comparing our operating
results on a period-to-period basis may not be meaningful, and you should not
rely on our past results as an indication of our future performance.
COVID-19 Pandemic
We are subject to risks and uncertainties as a result of the COVID-19 pandemic.
The extent of the impact of the COVID-19 pandemic on our business is highly
uncertain and difficult to predict as coronavirus continues to spread around the
world. There is still no vaccine, and treatments are limited. We have instituted
office closures, travel restrictions and continue with a mandatory
work-from-home policy for substantially all of our employees. The spread of
COVID-19 has impacted our supply chain operations through restrictions, reduced
capacity and shutdown of business activities by suppliers whom we rely on for
sourcing components and materials and third-party partners whom we rely on 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 WiFi, 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. Furthermore, our supply chain
continues to face constraints primarily due to challenges in sourcing components
and materials to manufacture our products, and future outbreaks could exacerbate
these constraints or cause further supply chain disruptions. The extent to which
the COVID-19 pandemic may materially impact our financial condition, liquidity
or results of operations is uncertain.
In the second quarter of 2020, we made the decision to embrace a
work-from-anywhere model, with many of our employees electing to work remotely
on a permanent basis. This operating mode reduces our physical facilities
requirements, and consequently, we established a restructuring plan to align our
business to a work-from-anywhere model and incurred facilities-related
restructuring charges of $5.1 million. Furthermore, in the second quarter of
2020 we realigned our product portfolio to reduce and consolidate certain legacy
product lines as customers accelerated their interest in our all-platform
offerings. These actions resulted in a component inventory accrual of $1.8
million and severance-related charges of $1.2 million.
Critical Accounting Policies and Estimates
Our financial statements are prepared in accordance with U.S. GAAP. These
accounting principles require us to make certain estimates and judgments that
can affect the reported amounts of assets and liabilities as of the date of the
financial statements, as well as the reported amounts of revenue and expenses
during the periods presented. Management bases its estimates, assumptions and
judgments on historical experience and on various other factors that are
believed to be reasonable under the circumstances. To the extent there are
material differences between these estimates and actual results, our financial
statements may be affected. 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, 2019. For the six months ended June 27, 2020, there have been
no significant changes in our critical accounting policies and estimates.

Our revenue increased by $18.7 million and $31.1 million for the three and six
months ended June 27, 2020, respectively, as compared to the corresponding
periods in 2019 due to higher systems revenue of $18.0 million and $30.2
million, respectively, and higher services revenue of $0.7 million and $0.9
million, respectively. The increase in systems revenue was primarily due to
higher revenue from our small, regional customers and, to a lesser extent, our
large-sized customers, as service providers accelerated some deployments to
respond to demand for network capacity and relieve network capacity constraints.
The increase in services revenue was due to continued ramp in our next
generation service offerings was only partially offset by lower professional
services related to CAF deployments.
For the three and six months ended June 27, 2020, revenue generated in the
United States was $108.2 million and $196.2 million, or 91% and 89% of our total
revenue, respectively, compared to $85.8 million and $161.6 million, or 86% and
85% of our total revenue, respectively, for the same period in 2019.
International revenue was $10.8 million and $24.5 million, or 9% and 11% of our
total revenue, respectively, for the three and six months ended June 27, 2020,
as compared to $14.5 million and $28.0 million, or 14% and 15% of our total
revenue, respectively, for the same period in 2019.
Only CenturyLink, Inc. accounted for more than 10% of the Company's total
revenue, representing 15% for both the three and six months ended June 27, 2020,
and 17% and 15% for the three and six months ended June 29, 2019, respectively.

Our cost of revenue increased by $7.0 million and $12.0 million for the three
and six months ended June 27, 2020, respectively, as compared with the
corresponding periods in 2019. The $7.2 million and $13.3 million increases in
our systems cost of revenue were less than the increases in revenue compared
with the corresponding periods in 2019, despite a charge of $1.8 million related
to our reduction and consolidation of legacy product lines taken in the second
quarter of 2020, and were partly due to favorable customer and product mix. The
decrease in services cost of revenue was mainly due to reduced personnel costs
for the three and six months ended June 27, 2020 compared with the corresponding
period in 2019.

Gross profit increased to $56.4 million and $102.0 million for the three and six
months ended June 27, 2020, respectively, from $44.7 million and $83.0 million
during the corresponding periods in 2019 primarily due to higher systems and
services gross margin.
During the three and six months ended June 27, 2020, systems gross margin was
negatively impacted by U.S. tariff and tariff-related costs of $0.7 million and
$1.7 million, or 65 and 80 basis points, respectively, and intangible asset
amortization of $0.7 million and $1.3 million, or 60 basis points for both
periods, respectively. Excluding the impact of U.S. tariff and tariff-related
costs and intangible assets amortization, systems gross margin was 50.1% and
49.1% for the three and six months ended June 27, 2020, respectively. During the
three and six months ended June 29, 2019, systems gross margin was negatively
impacted by U.S. tariff and tariff-related costs of $1.9 million and
$4.0 million, or 200 and 230 basis points, respectively. There was no intangible
asset amortization in the three and six months ended June 29, 2019. Excluding
the impact of U.S. tariff and tariff-related costs, systems gross margin was
48.6% and 48.5% for the three and six months ended June 29, 2019, respectively.
The increase in systems gross margin excluding U.S. tariff and tariff-related
costs and intangible assets amortization for the three months ended June 27,
2020 compared the corresponding period in 2019, was mainly due to continued
growth in our all-platform offerings along with favorable product and customer
mix.
Services gross margin increased for the three months ended June 27, 2020
compared to the corresponding period in 2019 due to lower personnel costs as our
service revenue mix shifts away from low gross margin deployment services to
higher gross margin software maintenance and services aligned with our platform
offerings.

Research and development expenses for the three months ended June 27, 2020
increased by $0.2 million as compared with the corresponding period in 2019
mainly due to higher personnel expenses of $0.7 million, primarily related to
incentive compensation expense, and higher stock-based compensation of $0.2
million. These increases were partially offset by decreases in depreciation and
amortization expense of $0.3 million and lower travel expenses of $0.2 million.
Research and development expenses for the six months ended June 27, 2020
increased by $1.6 million as compared with the corresponding period in 2019
mainly due to higher personnel expenses of $1.8 million, primarily related to
incentive compensation expense, higher outside services expenses of $0.8 million
and higher stock-based compensation of $0.2 million. These increases were
partially offset by decreases in depreciation and amortization expense of $0.4
million, lower equipment expenses of $0.3 million and lower travel expenses of
$0.3 million.

Sales and marketing expenses for the three months ended June 27, 2020 increased
by $1.6 million as compared with the corresponding period in 2019 primarily due
to higher personnel expenses of $1.7 million, mainly related to higher sales
incentive compensation expense and investments in sales headcount, higher
marketing expenses of $0.8 million and higher stock-based compensation of $0.2
million. These increases were partially offset by a decrease in travel expenses
of $1.4 million.
Sales and marketing expenses for the six months ended June 27, 2020 increased by
$2.9 million as compared with the corresponding period in 2019 primarily due to
higher personnel expenses of $2.7 million, mainly related to investments in
sales headcount and higher sales incentive compensation expense, and higher
marketing expenses of $1.4 million. These increases were partially offset by a
decrease in travel expenses of $1.6 million.

General and administrative expenses for the three months ended June 27, 2020
increased by $2.0 million as compared with the corresponding period in 2019
mainly due to capitalized cloud-computing amortization and subscription expenses
of $1.1 million as our cloud-based ERP system went live in January of 2020, an
increase in our bad debt allowance of $0.9 million, and an increase in personnel
expenses of $0.4 million, primarily related to incentive compensation expense.
These increases were partially offset by decreases in professional services fees
of $0.4 million and facilities expenses of $0.2 million.

of $2.2 million as our cloud-based ERP system went live in January of 2020, an
increase in personnel expenses of $1.7 million, primarily related to the
capitalization of internal resources related to our cloud-based ERP
implementation that lowered personnel expenses in 2019 as well as an increase in

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. See Note 5, "Balance Sheet Details" of the Notes
to Condensed Consolidated Financial Statements included in Part I, Item 1 of
this Quarterly Report on Form 10-Q for further details.

The effective tax rate for the three and six months ended June 27, 2020 was
determined using an estimated annual effective tax rate adjusted for discrete
items, if any, that occurred during the respective periods.
Deferred tax assets are recognized if realization of such assets is more likely
than not. We have established and continue to maintain a full valuation
allowance against our net deferred tax assets, with the exception of certain
foreign deferred tax assets, as we do not believe that realization of those
assets is more likely than not.
Our effective tax rate may be subject to fluctuation during the year as new
information is obtained, which may affect the assumptions used to estimate the
annual effective tax rate, including factors such as the mix of forecasted
pre-tax earnings in the various jurisdictions in which we operate, valuation
allowances against 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.

Liquidity and Capital Resources
We have funded our operations and investing activities primarily through cash
generated from operations, borrowings on our line of credit, financing
arrangements for certain lab equipment and consulting services and sales of our
common stock. As of June 27, 2020, we had cash and cash equivalents of $50.6
million, which consisted of deposits held at banks held at major financial
institutions.
Operating Activities
Net cash provided by operating activities was $3.9 million for the six months
ended June 27, 2020 and consisted of $17.0 million of non-cash charges and $1.9
million of cash flow decreases reflected in the net change in assets and
liabilities, partially offset by a net loss of $11.2 million. Cash flow
decreases resulting from the net change in assets and liabilities primarily
consisted of an increase in accounts receivable of $12.1 million, due to product
shipment timing. In addition, there was a decrease in deferred revenue of $0.9
million due to the invoice timing of our customer support and subscription
offerings and a decrease in accounts payable of $0.7 million, primarily due to
timing of payments to our suppliers. These changes were partially offset by an
increase in accrued liabilities of $7.9 million, due to an increase in accruals
related to our restructuring activities and an increase our liability for
components at certain suppliers. In addition, there was a decrease in inventory
of $3.5 million due to lower deliveries as a result of the supply disruption
during 2020 and an increase in prepaid expenses and other assets of $1.2
million, due to an increase in our VAT receivable and employee receivables
related to income tax obligations associated with our NQ ESPP.
Non-cash charges primarily consisted of depreciation and amortization of $7.0
million, stock-based compensation of $6.2 million and lease restructuring
charges of $3.7 million.
During the six months ended June 29, 2019, net cash used in operating activities
was $3.3 million and consisted of a net loss of $14.8 million partially offset
by $1.0 million of cash flow increases reflected in the net change in assets and
liabilities and by $10.4 million of non-cash charges. Cash flow increases
resulting from the net change in assets and liabilities primarily consisted of a
decrease in accounts receivable of $6.8 million, mainly due to lower sales, a
decrease in inventory of $4.8 million, primarily due to the transfer of raw
material inventory to our new CM and higher excess and obsolete reserves, an
increase in deferred revenue of $3.2 million due to increased support contracts,
software maintenance and Calix Cloud subscriptions and a decrease in prepaid
expenses and other assets of $1.7 million, mainly due to operating lease asset
amortization. This was partially offset by a decrease in accrued liabilities of
$10.3 million, mainly related to incentive compensation payments to employees
and ESPP purchases, a decrease in accounts payable of $2.7 million, primarily
due to less inventory purchases, a decrease in other long-term liabilities of
$2.5 million, mainly due to operating lease liability amortization.
Non-cash charges primarily consisted of stock-based compensation of $5.7 million
and depreciation and amortization of $4.6 million.
Investing Activity
For the six months ended June 27, 2020 we invested $4.5 million in capital
expenditures consisting primarily of purchases of test equipment and computer
equipment. Similarly, for the six months ended June 29, 2019, we invested $9.5
million in capital expenditures consisting primarily of purchases of test
equipment, computer equipment and software.
Financing Activities
Net cash provided by financing activities of $4.5 million for the six months
ended June 27, 2020 mainly consisted of proceeds from the issuance of common
stock from stock option exercises of $5.6 million and from our employee stock
purchase plans of $4.7 million. These inflows were partially offset by the
partial re-payment of our line of credit of $4.0 million, payments related to
financing arrangements of $1.5 million and payments to originate the credit line
of $0.3 million.
Net cash used in financing activities of $1.9 million for the six months ended
June 29, 2019 mainly related to reduced borrowing from the line of credit of
$5.0 million and payments for financing arrangements of $1.3 million, partially
offset by proceeds from the issuance of common stock under our employee stock
purchase plans of $4.2 million and from stock option exercises of $0.3 million.
Working Capital and Capital Expenditure Needs
Our material cash commitments include non-cancelable firm purchase commitments,
contractual obligations under our loan and security agreement with Bank of
America, or BofA Loan Agreement, normal recurring trade payables,
compensation-related and expense accruals, operating leases, minimum
revenue-share obligations and obligations from financing arrangements. We
believe that our outsourced approach to manufacturing provides us significant
flexibility in both managing inventory levels and financing our inventory. In
the event that our revenue plan does not meet our expectations, we may be
required to curtail or eliminate expenditures to mitigate the impact on our
working capital.

In January 2020, we terminated our Silicon Valley Bank loan and security
agreement and entered into a new loan and security agreement with Bank of
America, N.A. The BofA Loan Agreement provides for a revolving facility up to a
principal amount of up to $35.0 million, including a $10.0 million sublimit for
letters of credit. The BofA Loan Agreement matures, and all outstanding amounts
become due and payable, in January 2023. The BofA Loan Agreement is secured by
substantially all of our assets, including our intellectual property. Effective
July 1, 2020, loans under the credit facility will bear interest at a rate per
annum equal to either LIBOR (customarily defined) plus an applicable margin
between 1.5% to 2.0% or Prime Rate (customarily defined) plus an applicable
margin between 0.5% to 1.0%, in each case largely based on a fixed charge
coverage ratio measured at the end of each fiscal quarter. The availability of
borrowings under the BofA Loan Agreement is subject to certain conditions and
requirements, including among others, if at any time our availability is less
than $5.0 million, we must maintain a minimum fixed charge coverage ratio, or
FCCR, of 1.0 to 1.0. As of June 27, 2020, we were in compliance with these
requirements, had borrowings outstanding of $26.0 million, availability of $9.0
million and an FCCR of 4.1 to 1.0. Our interest rate on the line of credit was
4.5% as of the quarter ended June 27, 2020 and decreased to 3.75% on July 1,
2020.
In March 2018, we entered into an agreement with a vendor to develop software
products pursuant to which we would become obligated, if the vendor delivered
software that meets our technical requirements for commercial sale, to make
minimum revenue-share payments of $15.8 million over the subsequent three years.
The payments are based on a revenue-share rate applied to revenue from developed
product sales subject to a minimum and a maximum aggregate amount over the
three-year sales period. We had our first sale in August 2019. Revenue-share
payments are paid quarterly in arrears, and we began making payments in the
first quarter of 2020.
During 2018, we entered into financing arrangements to purchase lab equipment
for approximately $5.1 million. Each agreement is to be paid over 36 months with
a weighted average interest rate of 6.2%. As of June 27, 2020, we had $2.1
million outstanding under these financing arrangements.
From 2017 to 2020, in connection with our ERP implementation, we entered into
financing arrangements for consulting services of $5.5 million. The current
amounts due under this agreement are to be paid over a weighted average term of
2.4 years with a weighted average interest rate of 6.2%. As of June 27, 2020,
there was $1.9 million outstanding under this arrangement.
We believe, based on our current operating plan and expected operating cash
flows, that our existing cash and cash equivalents, along with available
borrowings under our BofA Loan Agreement, will be sufficient to meet our
anticipated cash needs for at least the next twelve months. Our future capital
requirements will depend on many factors including our rate of revenue growth;
timing of customer payments and payment terms, particularly of larger customers;
the timing and extent of spending to support development efforts; our ability to
manage product cost, including the cost impact of the U.S. tariffs as well as
the possibility of additional tariffs or costs associated with disruptions in
global trade and relations that may impact our product costs and higher
component costs associated with new technologies; the global impact of the
COVID-19 pandemic, particularly if restrictions are prolonged; our ability to
implement efficiencies and maintain product margin levels; the expansion of
sales and marketing activities; the success of revenue share programs; the
timing of introductions and timing and rate of customer adoption of new products
and enhancements to existing products; the slowdowns or declines in customer
purchases of traditional systems; acquisition of new capabilities or
technologies; and the continued market acceptance of our products. If we are
unable to execute on our current operating plan or generate positive operating
income and positive cash flows, our liquidity, results of operations and
financial condition will be adversely affected, and we may fail to meet the
borrowing base requirements or comply with the covenants in the BofA Loan
Agreement, in which case we may not be able to borrow under the BofA Loan
Agreement. We may need to seek other sources of liquidity, including the sale of
equity or incremental borrowings, to support our working capital needs. In
addition, we may choose to seek other sources of liquidity even if we believe we
have generated sufficient cash flows to support our operational needs. There is
no assurance that any other sources of liquidity may be available to us on
acceptable terms or at all. If we are unable to generate sufficient cash flows
or obtain other sources of liquidity, we will be forced to limit our development
activities, reduce our investment in growth initiatives and institute
cost-cutting measures, all of which may adversely impact our business and
potential growth.
