Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion should be read in conjunction with the consolidated financial statements and the related notes. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include, but are not limited to, those discussed below and those listed under Item 1A, Risks Factors. For discussion of comparison of our results of operations and cash flows for the fiscal years ended December 31, 2021 and 2020, refer to Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the SEC on February 28,2022.
Business Overview
We are a leading global provider of (i) versatile and high performance video delivery software, products, system solutions and services that enable our customers to efficiently create, prepare, store, playout and deliver a full range of high-quality broadcast and streaming video services to consumer devices, including televisions, personal computers, laptops, tablets and smart phones and (ii) broadband solutions that enable broadband operators to more efficiently and effectively deploy high-speed internet, for data, voice and video services to consumers’ homes.
We classify our total revenue in two categories, “Appliance and integration” and “SaaS and service.” The “Appliance and integration” revenue category includes hardware, licenses and professional services and is reflective of non-recurring revenue, while the “SaaS and service” category includes usage fees for our SaaS platform and support service revenue from our appliance-based customers and reflects our recurring revenue stream.
We conduct business in three geographic regions - the Americas, EMEA and APAC - and operate in two segments, Video and Broadband. During the third quarter of fiscal 2022, our Cable Access segment was renamed the Broadband segment to reflect a broader strategic view of the category. There has been no change to the composition of the segment; therefore, no prior periods were restated. Our Video business sells video processing, production and playout solutions, and services worldwide to broadband operators and satellite and telecommunications (“telco”) Pay-TV service providers, which we refer to collectively as “service providers,” as well as to broadcast and media companies, including streaming media companies. Our Video business infrastructure solutions are delivered either through shipment of our products, software licenses or as SaaS subscriptions. Our Broadband business sells broadband access solutions and related services, including our CableOS software-based broadband access solution, to broadband operators globally.
Historically, our revenue has been dependent upon spending in the cable, satellite, telco, broadcast and media industries, including streaming media. Our customers’ spending patterns are dependent on a variety of factors, including but not limited to: economic conditions in the United States and international markets, including the impacts of the COVID-19 pandemic and the Russia-Ukraine conflict, such as inflation, rising interest rates, potential supply chain disruptions, volatility in capital markets and foreign currency fluctuations; access to financing; annual budget cycles of each of the industries we serve; impact of industry consolidations; and customers suspending or reducing spending in anticipation of new products or new standards, new industry trends and/or technology shifts. If our product portfolio and product development plans do not position us well to capture an increased portion of the spending in the markets in which we compete, our revenue may decline. As we attempt to further diversify our customer base in these markets, we may need to continue to build alliances with other equipment manufacturers and suppliers, cloud service providers, content providers, resellers and system integrators, managed services providers and software developers; adapt our products for new applications; take orders at prices resulting in lower margins; and build internal expertise to handle the particular operational, payment, financing and/or contractual demands of our customers, which could result in higher operating costs for us.
More recently, the United States has experienced high levels of inflation, which may result in decreased demand for our products and services, increases in our operating costs including our labor costs, constrained credit and liquidity, reduced customer spending and volatility in financial markets. The Federal Reserve has raised, and may continue to raise, interest rates in response to concerns over inflation risk. There continues to be uncertainty in the changing market and economic conditions, including the possibility of additional measures that could be taken by the Federal Reserve and other government agencies, related to macroeconomic conditions, geopolitical disruptions and concerns over inflation risk.

We believe a material and growing portion of the opportunities for our Video business are linked to the industry and our customers (i) continuing to adopt streaming technologies to capture, process and deliver video content to consumers and, increasingly, utilizing public cloud solutions like our VOS SaaS platform to do so; (ii) transforming existing broadcast infrastructure workflows into more flexible, efficient and cost-effective operations running in public clouds; and (iii) for those customers maintaining on-premise video delivery infrastructure, continuing to upgrade and replace aging equipment with next-generation software-based appliances that significantly reduce operational complexity. Our Video business strategy is focused on continuing to develop and deliver products, solutions and services to enable and support these trends.
Our Broadband strategy is focused on continuing to develop and deliver software-based broadband access technologies, which we refer to as our CableOS solutions, to our broadband operator customers. We believe our CableOS software-based broadband access solutions are superior to hardware-based systems and deliver unprecedented scalability, agility and cost savings for our customers. Our CableOS solutions, which can be deployed based on a centralized, DAA or hybrid architecture, enable our customers to migrate to multi-gigabit broadband capacity and the fast deployment of DOCSIS and/or FTTH data, video and voice services. We believe our CableOS solutions resolve space and power constraints in broadband operator facilities, eliminate dependence on hardware upgrade cycles and significantly reduce total cost of ownership, and are helping us become a major player in the broadband access market. In the meantime, we believe our Broadband segment will continue to gain momentum in the marketplace as our customers adopt and deploy our virtualized DOCSIS, CMTS and FTTH solutions and distributed access architectures. We continue to make progress in the development of our CableOS solutions and in the growth of our CableOS business, with expanded commercial deployments, field trials, and customer engagements.
Critical Accounting Estimates
The preparation of consolidated financial statements and related disclosures, which are prepared in accordance with GAAP, requires Harmonic to make judgments, assumptions and estimates that affect the reported amounts of assets and liabilities, the disclosure of contingencies and the reported amounts of revenue and expenses in the financial statements and accompanying notes. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions we believe to be reasonable under the circumstances. Material differences may result in the amount and timing of revenue and expenses if different judgments or different estimates were made. Refer to Note 2 of the Notes to our Consolidated Financial Statements for details of our accounting estimates.
We believe that the following critical accounting estimates involve a greater degree of judgement or complexity than our other accounting estimates. Accordingly, the critical accounting estimates that we believe have the most significant impact on Harmonic’s financial statements are set forth below:
•Revenue recognition;
•Valuation of inventories; and
•Accounting for income taxes.
Revenue Recognition
We recognize revenue from contracts with customers using the following five steps:
a) Identify the contract(s) with a customer;
b) Identify the performance obligations in the contract;
c) Determine the transaction price;
d) Allocate the transaction price to the performance obligations in the contract; and
e) Recognize revenue when (or as) we satisfy a performance obligation.
Refer to Note 4, “Revenue,” of the Notes to our Consolidated Financial Statements for additional information about our revenue recognition policies, including critical judgments and estimates associated with our revenue recognition.

Valuation of Inventories
We state inventories at the lower-of-cost (determined on first-in, first-out basis) or net realizable value. We write down the cost of excess or obsolete inventory to net realizable value based on future demand forecasts and historical consumption. If there were to be a sudden and significant decrease in demand for our products, or if there were a higher incidence of inventory obsolescence because of rapidly changing technology and customer requirements, we could be required to record additional charges for excess and obsolete inventory and our gross margin could be adversely affected. Inventory management is of critical importance in order to balance the need to maintain strategic inventory levels to ensure competitive lead times against the risk of inventory obsolescence because of rapidly changing technology and customer requirements.
Accounting for Income Taxes
In preparing our consolidated financial statements, we estimate our income taxes for each of the jurisdictions in which we operate. This involves estimating our actual current tax expense and assessing temporary differences resulting from differing treatment of items, such as reserves and accruals, for tax and accounting purposes. These temporary differences result in deferred tax assets and liabilities, which are included within our Consolidated Balance Sheets. We maintain valuation allowances for deferred tax assets when it is likely that all or a portion of a deferred tax asset will not be realized. In determining whether a valuation allowance is warranted, we take into account such factors as prior earnings history, expected future earnings, unsettled circumstances that, if unfavorably resolved, would adversely affect the utilization of a deferred tax asset.
We are subject to examination of our income tax returns by various tax authorities on a periodic basis. We regularly assess the likelihood of adverse outcomes resulting from such examinations to determine the adequacy of our provision for income taxes. We apply the provisions of the applicable accounting guidance regarding accounting for uncertainty in income taxes, which requires application of a more-likely-than-not threshold to the recognition and derecognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits us to recognize a tax benefit measured at the largest amount of such tax benefit that, in our judgment, is more than fifty percent likely to be realized upon settlement. It further requires that a change in judgment related to the expected ultimate resolution of uncertain tax positions be recognized in earnings in the period in which such determination is made.
We file annual income tax returns in multiple taxing jurisdictions around the world. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, we believe that our reserves for income taxes reflect the most likely outcome. We adjust these reserves, as well as the related interest and penalties, in light of changing facts and circumstances. If our estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary. Any changes in estimate, or settlement of any particular position, could have a material impact on our operating results, financial condition and cash flows.

Restructuring and Related Charges
We have implemented several restructuring plans in the past few years. The goal of these plans is to bring operational expenses to appropriate levels relative to our net revenues, while simultaneously implementing extensive company-wide expense control programs. We account for our restructuring plans under the authoritative guidance for exit or disposal activities. The restructuring and related charges are included in “Cost of revenue” and “Operating expenses-restructuring and related charges” in the Consolidated Statements of Operations.

Interest expense, net decreased in 2022, as compared to 2021, primarily due to the adoption of ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, on January 1, 2022, which eliminated debt discounts on the 2022 Notes and 2024 Notes resulting in an elimination of debt discount amortization expense. Refer to Note 2, “Recently Issued Accounting Pronouncements,” of the Notes to our Consolidated Financial Statements for details of the ASU adoption. The decrease is also attributed to the repayment of the 2022 Notes in December 2022 upon their maturity.

Other income (expense), net is primarily comprised of foreign exchange gains and losses on cash, accounts receivable and intercompany balances denominated in currencies other than the functional currency of the reporting entity. Our foreign currency exposure is primarily driven by the fluctuations in the foreign currency exchanges rates of the Euro, British pound, Japanese yen and Israeli shekel. The change in other income (expense), net in 2022, as compared to 2021, was primarily due to a gain of $4.2 million recognized on the sale of our investment in Encoding.com in May 2022. Refer to Note 3, “Investment in Equity Securities,” of the Notes to our Consolidated Financial Statements for details on the sale of investment in Encoding.com.

The change in provision for (benefit from) income taxes for 2022, as compared to 2021, was primarily due to mandatory capitalization and amortization of research and development expenses in the United States starting January 1, 2022, as required by the Tax Cuts and Jobs Act, which resulted in additional income tax in the United States, offset by the utilization of net operating losses and tax credits. In 2021 there was a valuation allowance release of $8.6 million in a foreign jurisdiction in recognition of their improved historical earnings and increasing future projected earnings which contributed to the tax benefit recognized for fiscal 2021.

Video
Our Video segment net revenue decreased in 2022, as compared to 2021, primarily due to a reduction in sales of Appliance products, reflecting lower shipments of appliance products and the impact of ceasing sales activities in Russia, partially offset by an increase in SaaS and service revenue, reflecting increasing usage from existing customers and activation of new SaaS customers. Video segment operating margin decreased in 2022, as compared to 2021, primarily due to the decrease in revenue and increased investment in research and development to support strategic transition to the SaaS business, partially offset by gross margin expansion in SaaS and Appliance.
Broadband
Our Broadband segment net revenue increased in 2022, as compared to 2021, primarily due to the increased penetration of our existing customers and new customer deployments in 2022. Our Broadband segment operating margin increased in 2022, as compared to 2021, primarily due to the increase in revenue and margin expansion driven by favorable mix and cost savings in freight and shipping as a result of strategic investments in inventory.
Liquidity and Capital Resources
We expect to continue to manage our cash from operations effectively, together with deploying cash in working capital for growth. The cash we generate from our operations enables us to fund ongoing operations, our research and development projects for new products and technologies, and other business activities. We continually evaluate our cash needs and may decide it is best to raise additional capital or seek alternative financing sources to fund our operations, the growth of our business, to take advantage of unanticipated strategic opportunities, or to strengthen our financial position, including through drawdowns on existing or new debt facilities or new financing (debt and equity) funds. In the future, we may enter into other arrangements for potential investments in, or acquisitions of, complementary businesses, services or technologies, which could require us to seek additional equity or debt financing. Additional funds may not be available on terms favorable to us or at all. Conversely, we may also from time to time determine that it is in our best interests to voluntarily repay certain indebtedness early. We repaid $37.7 million of principal in cash of the 2022 Notes upon maturity in December 2022. We believe that our current sources of funds will provide us with adequate liquidity during the 12-month period following December 31, 2022, as well as in the long-term.

Material Cash Requirements
Our principal uses of cash will include repayments of debt and related interest, purchases of inventory, stock repurchases, payments for payroll, restructuring expenses, and other operating expenses related to the development and marketing of our products, purchases of property and equipment, facility leases, and other contractual obligations for the foreseeable future.
As of December 31, 2022, we had outstanding $131.4 million in aggregate principal amount of indebtedness, consisting of our 2024 Notes and other debts, of which $4.8 million is scheduled to become due in the 9-month period following December 31, 2022. As of December 31, 2022, our total minimum lease payments are $37.6 million, of which $7.1 million is due in the 12-month period following December 31, 2022. For details regarding our indebtedness and lease obligations, refer to Note 12, “Convertible Notes and Other Debts”, and Note 5, “Leases”, respectively, of the Notes to our Consolidated Financial Statements included elsewhere in this Annual Report on Form 10-K.
On February 3, 2022, the Board of Directors authorized us to repurchase, from time to time, up to $100 million of our outstanding shares of common stock through February 2025, at such time and such prices as management may decide. The program does not obligate us to repurchase any specific number of shares and may be discontinued at any time. As of December 31, 2022, approximately $94.9 million of the share repurchase authorization remained available.
Sources and Conditions of Liquidity
Our sources to fund our material cash requirements are predominantly from our sales of our products and services and, when applicable, proceeds from debt facilities and debt and equity offerings.
As of December 31, 2022, our principal sources of liquidity consisted of cash and cash equivalents of $89.6 million, net accounts receivable of $108.4 million, and our $25.0 million revolving credit facility with JPMorgan Chase Bank, N.A. Refer to Note 12, “Convertible Notes and Other Debts,” of the Notes to our Consolidated Financial Statements for details of the Credit Agreement.
Our cash and cash equivalents of $89.6 million as of December 31, 2022 consisted of bank deposits held throughout the world, of which $67.7 million was held outside of the United States. At present, such foreign funds are considered to be indefinitely reinvested in foreign countries to the extent of indefinitely reinvested foreign earnings. In the event funds from foreign operations are needed to fund cash needs in the United States and if U.S. taxes have not already been previously accrued, we may be required to accrue and pay additional U.S. and foreign withholding taxes in order to repatriate these funds.

Operating Activities
Net cash provided by operating activities decreased $35.5 million in 2022, as compared to 2021, primarily due to an increase of cash used for working capital mainly due to timing of accounts payable and investments in inventories, partially offset by higher net income in fiscal 2022.
We expect that cash provided by or used in operating activities may fluctuate in future periods as a result of a number of factors, including but not limited to, the impact of COVID-19, the Russia-Ukraine conflict and related macroeconomic conditions on demand for our offerings, fluctuations in our operating results, shipment linearity, accounts receivable collections performance, inventory and supply chain management, and the timing and amount of compensation and other payments.
Investing Activities
Net cash used in investing activities decreased $11.7 million in 2022, as compared to 2021, primarily due to proceeds from the sale of our investment in Encoding.com and lower purchases of property and equipment in fiscal 2022.

Financing Activities
Net cash used in financing activities increased $51.1 million in 2022 compared to 2021, primarily due to the repayment of the $37.7 million principal of the 2022 Notes in December 2022, lower proceeds from issuance of common stock to employees through stock option exercises, and stock repurchase transactions initiated in fiscal 2022.
