SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated financial statements include those of Harmonic and its wholly-owned subsidiaries, after elimination of all intercompany accounts and transactions. The Company has reclassified certain amounts previously reported in its consolidated financial statements that were not material, to conform to the current presentation. The Company’s fiscal quarters are based on 13-week periods, except for the fourth quarter which ends on December 31.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s reported financial positions or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. If estimates or assumptions differ from actual results, subsequent periods are adjusted to reflect more current information.

Cash and Cash Equivalents

All highly liquid investments with an original maturity of three months or less at the date of purchase are considered cash equivalents. The carrying amount of cash and cash equivalents approximates fair value because of the short maturity of those instruments.

Credit Risk and Major Customers/Supplier Concentration

Financial instruments which subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and accounts receivable. Cash and cash equivalents are invested in short-term, highly liquid, investment-grade instruments, in accordance with the Company’s investment policy. The investment policy limits the amount of credit exposure to any one financial institution, commercial or governmental issuer.

The Company’s accounts receivable are derived from sales to worldwide cable, satellite, telco, and broadcast and media companies. The Company generally does not require collateral from its customers, and performs ongoing credit evaluations of its customers and provides for expected losses. The Company maintains an allowance for doubtful accounts based upon the expected collectability of its accounts receivable. One customer had a balance greater than 10% of the Company’s net accounts receivable balance as of December 31, 2025. Two customers had a balance greater than 10% of the Company’s net accounts receivable balance as of December 31, 2024. During the years ended December 31, 2025 and 2023, one customer accounted for more than 10% of the Company’s total net revenue. During the year ended December 31, 2024, two customers each accounted for more than 10% of the Company’s total net revenue.

Certain of the components and subassemblies included in the Company’s products are obtained from a single source or a limited group of suppliers. Although the Company seeks to reduce dependence on those sole source and limited source suppliers, the partial or complete loss of certain of these sources could have at least a temporary adverse effect on the Company’s results of operations and damage customer relationships.

Revenue Recognition

The Company classifies its total revenue in two categories on the face of the statement of operations, “Appliance and integration” and “SaaS and service”. Appliance and integration revenue includes revenue from the sale of hardware products and perpetual software licenses, as well as the associated professional services such as testing, design, installation, commissioning, and integration, collectively referred to as “professional services”. These professional service agreements, associated with the sale of hardware products and perpetual software licenses, are typically of a short duration and are considered an important component of the appliance business by management.

The Company applies the provisions of ASC 606, Revenue from Contracts with Customers (“ASC 606”) as a single standard for revenue recognition that applies to all of its hardware products, software licenses and services arrangements and generally require revenues to be recognized upon the transfer of control of promised goods or services provided to its customers, reflecting the amount of consideration the Company expects to receive for those goods or services. Pursuant to ASC 606, revenue is recognized upon the application of the following steps:

•

identification of the contract, or contracts, with a customer;

•

identification of the performance obligations in the contract;

•

determination of the transaction price;

•

allocation of the transaction price to each performance obligation in the contract; and

•

recognition of revenues when, or as, the contractual performance obligations are satisfied.

Hardware and Software: Revenue from the sale of hardware and software products is recognized when control is transferred. For most of the Company’s product sales (including sales to distributors and system integrators), control is transferred at the time the product is shipped or delivery has occurred because the customer has significant risks and rewards of ownership of the asset and the Company has a present right to payment at that time.

Shipping and handling costs are accounted for as a fulfillment cost and are recorded in “Cost of revenue” in the Company’s Consolidated Statements of Operations. Sales tax and other amounts collected on behalf of third parties are excluded from the transaction price.

Professional services: Revenues from professional services are generally recognized as the services are performed.

SaaS services: Revenue for SaaS service is recognized ratably over the contractual term as the customer simultaneously receives and consumes the benefit of the underlying service.

Support and maintenance: Support and maintenance services are satisfied ratably over time as the customer simultaneously receives and consumes the benefits of the services.

Arrangements with Multiple Performance Obligations: The Company has revenue arrangements that include multiple performance obligations. The Company allocates the transaction price to all distinct performance obligations based on their relative standalone selling prices (“SSP”). The Company may exercise judgment when determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together. The determination of SSP is based on the contractually stated, observable prices of the promised goods and services charged when sold separately to the customer. Where SSP is not directly observable, we determine the SSP using information which considers multiple factors including, but not limited to, major product groupings, gross margin objectives and pricing practices. Pricing practices taken into consideration include discounts offered and applicable price lists.

Contract Balances: Deferred revenue represents the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. The Company’s payment terms vary by the type and location of its customer and the products or services offered. The term between invoicing and when payment is due is not significant. For certain products or services and customer types, the Company requires payment before the products or services are delivered to the customer.

The amount of revenues recognized during the years ended December 31, 2025 and 2024 that were included in the opening deferred revenue balance as of January 1, 2025 and 2024, respectively, were $13.4 million and $10.4 million.

Contract assets exist when the Company has satisfied a performance obligation but does not have an unconditional right to consideration (e.g., because the entity first must satisfy another performance obligation in the contract before it is entitled to invoice the customer).

Contract assets and deferred revenue consisted of the following:


	As of December 31,
(in thousands)	2025		2024
Contract assets	$	1,959	$	1,035
Deferred revenue	$	33,006	$	16,996

Contract assets and the non-current portion of deferred revenue are reported as components of “Prepaid expenses and other current assets” and “Other non-current liabilities”, respectively, on the Consolidated Balance Sheets.

Remaining performance obligations represent contracted revenues that had not yet been recognized and future revenue recognition is expected. The aggregate balance of the Company’s remaining performance obligations as of December 31, 2025, was $573.8 million, of which approximately 53% is expected to be recognized as revenue over the next twelve months and the remainder thereafter.

Contract costs: The incremental costs of obtaining a contract are capitalized if the costs are expected to be recovered. Costs that are recognized as assets are amortized on a straight-line basis over the period during which the related goods or services transfer to the customer. Costs incurred to fulfill a contract are capitalized if they are not covered by other relevant guidance, relate directly to a contract, will be used to satisfy future performance obligations, and are expected to be recovered.

The balances of net capitalized contract costs included in the Company’s Consolidated Balance Sheets were as follows:


(in thousands)		As of December 31,
Balance Sheet Location:	2025		2024
Prepaid expenses and other current assets	$	1,139	$	560
Other non-current assets		1,005		552
Total net capitalized contract costs	$	2,144	$	1,112

The amortization of the capitalized contract costs for the years ended December 31, 2025, 2024 and 2023 was $0.9 million, $0.5 million and $0.1 million, respectively.

Refer to Note 13, “Segment Information, Geographic Information and Customer Concentration” for disaggregated revenue information.

Inventories

Inventories are stated at the lower of cost (determined on first-in, first-out basis) or net realizable value. The cost of inventories is comprised of material and manufacturing labor and overheads. The Company establishes provisions for excess and obsolete inventories to reduce such inventories to their estimated net realizable value after evaluation of historical sales, future demand and market conditions, expected product life cycles and current inventory levels. Such provisions are charged to cost of revenue in the Company’s Consolidated Statements of Operations.

Property and Equipment

Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Estimated useful lives are generally five years for furniture and fixtures, three years for software and four years for machinery and equipment. Depreciation for leasehold improvements are computed using the shorter of estimated useful lives or the terms of the related leases. The Company reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. For the year ended December 31, 2025, the Company recognized impairment charges of $0.3 million related to leasehold improvements. For the year ended December 31, 2024, the Company recognized impairment charges of $4.3 million related to leasehold improvements. Refer to Note 4, “Leases” for more details. For the year ended December 31, 2023, there was no impairment charges for property and equipment.

Goodwill

Goodwill is assigned to one or more reporting segments on the date of acquisition. We review our goodwill for impairment annually during our fourth quarter of each fiscal year and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of any one of our reporting units below its respective carrying amount. The Company monitors changing business conditions as well as industry and economic factors, among others, for events which could trigger the need for an interim impairment analysis. In performing our goodwill impairment test, we first perform a qualitative assessment, which requires that we consider events or circumstances including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, changes in management or key personnel, changes in strategy, changes in customers, changes in the composition or carrying amount of a reporting segment’s net assets and changes in our stock price. If, after assessing the totality of events or circumstances, we determine that it is more likely than not that the fair values of our reporting segments are greater than the carrying amounts, then the quantitative goodwill impairment test is not performed.

If the qualitative assessment indicates that the quantitative analysis should be performed, we then evaluate goodwill for impairment by comparing the fair value of each of our reporting segments to its carrying value, including the associated goodwill. To determine the fair values, we use the market approach based on comparable publicly traded companies in similar lines of businesses and the income approach based on estimated discounted future cash flows. Our cash flow assumptions consider historical and forecasted revenue, operating costs and other relevant factors.

The changes in the Company's carrying amount of goodwill are as follows:


(in thousands)	Carrying Amount
Balance as of December 31, 2023	$	60,781
Foreign currency translation adjustment		(8)
Balance as of December 31, 2024	$	60,773
Foreign currency translation adjustment		127
Balance as of December 31, 2025	$	60,900

In the fourth quarter of 2025, we determined that our Video reporting segment met the criteria to be classified as held-for-sale. Accordingly, we tested goodwill for impairment and concluded that the fair value of the reporting unit had declined below its carrying value. As a result, we recorded a goodwill impairment charge of $57.5 million which is included within “Loss from discontinued operations, net of tax” in the consolidated statement of operations. No goodwill impairment charges were recorded for the year ended December 31, 2024 and 2023. For additional information on the pending disposition of the Video business, refer to Note 3, "Discontinued Operations."

Leases

The Company determines if an arrangement is a lease at inception. Operating lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company’s lease contracts do not provide an implicit borrowing rate; hence the Company determined the incremental borrowing rate based on information available at lease commencement to determine the present value of lease liability. Right-of-use (“ROU”) assets related to our operating lease liabilities are measured at lease inception based on the initial measurement of the lease liability, plus any prepaid lease payments and less any lease incentives. As of December 31, 2025, the Company has operating leases primarily consisting of facilities with remaining lease terms of 1 year to 7 years, some of which included the option to extend the term. Optional periods to extend the lease, including by not exercising a termination option, are included in the lease term when it is reasonably certain that the option will be exercised. The Company recognizes operating lease expense on a straight-line basis over the lease term and classify both the ROU assets amortization and imputed interest as operating expenses. Operating leases are included in “Operating lease right-of-use assets”, “Operating lease liabilities, current”, and “operating lease liabilities, non-current” in the Consolidated Balance Sheets.

Foreign Currency

The functional currency of the Company’s Israeli and Swiss subsidiaries is the U.S. dollar. All other foreign subsidiaries use the respective local currency as the functional currency. When the local currency is the functional currency, gains and losses from translation of these foreign currency financial statements into U.S. dollars are recorded as a separate component of other comprehensive income (loss) in stockholders’ equity.

The Company’s foreign currency exposure is also related to its net position of monetary assets and monetary liabilities held by its foreign subsidiaries in their nonfunctional currencies. These monetary assets and liabilities are being remeasured into the subsidiaries’ respective functional currencies using exchange rates as of the balance sheet date. Such remeasurement gains and losses are included in “Other income (expense), net” in the Company’s consolidated statements of operations. During the years ended December 31, 2025 and 2023, the Company recorded remeasurement loss of approximately $1.4 million and $0.2 million, respectively. During the year ended 2024, the Company recorded remeasurement gain of approximately $3.3 million.

Research and Development

Research and development (“R&D”) costs are expensed as incurred and consist primarily of employee salaries and related expenses, contractors and outside consultants, supplies and materials, equipment depreciation and facilities costs, all associated with the design and development of new products and enhancements of existing products.

Restructuring and Related Charges

The Company’s restructuring charges consist primarily of employee severance, one-time termination benefits related to the reduction of its workforce, and other costs. Liabilities for costs associated with a restructuring activity are recognized when the liability is incurred and are measured at fair value. One-time termination benefits are expensed at the date the entity notifies the employee, unless the employee must provide future service, in which case the benefits are expensed ratably over the future service period. Termination benefits are calculated based on regional benefit practices and local statutory requirements.

Warranty

The Company accrues for estimated warranty costs at the time of revenue recognition and records such accrued liabilities as part of cost of revenue. Management periodically reviews its warranty liability and adjusts the accrued liability based on the terms of warranties provided to customers, historical and anticipated warranty claims experience, and estimates of the timing and cost of warranty claims.

Advertising Expenses

All advertising costs are expensed as incurred and included in “Selling, general and administrative expenses” in the Company’s Consolidated Statements of Operations. Advertising expense was $0.2 million, $0.3 million and $0.4 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Stock-based Compensation

The Company measures and recognizes compensation expense for all stock-based compensation awards made to employees, including stock options, restricted stock units (“RSUs”) and stock purchase rights under the Company’s Employee Stock Purchase Plan (“ESPP”), based upon the grant-date fair value of those awards. The Company recognizes the impact of forfeitures as they occur.

The fair value of the Company’s stock purchase rights under ESPP is estimated at grant date using the Black-Scholes option pricing model. The fair value of the Company’s RSUs and performance-based RSUs (“PRSUs”) is calculated based on the market value of the Company’s stock at the grant date. The fair value of the Company’s market-based RSUs (“MRSUs”) is estimated using the Monte-Carlo valuation model with market vesting conditions.

The Company recognizes the stock-based compensation expense for RSUs, PRSUs, MRSUs and stock purchase rights under ESPP on straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes the stock-based compensation expense for PRSUs based on the probability of achieving performance criteria defined in the PRSU agreements. The Company estimates the number of PRSUs ultimately expected to vest and recognizes expense using the graded vesting attribution method over the requisite service period. Changes in the estimates related to probability of achieving certain performance criteria and number of PRSUs expected to vest could significantly affect the related stock-based compensation expense from one period to the next. The Company recognizes the expense for MRSUs over the requisite services periods regardless of whether the market conditions are satisfied.

Income Taxes

The Company accounts for income taxes using the asset and liability method of accounting for income taxes. The Company calculates and provides for income taxes in each of the tax jurisdictions in which it operates. The deferred tax assets and liabilities are recognized for future tax consequences attributable to temporary differences between the financial statement carrying values of existing assets and liabilities and their respective tax bases and all operating losses carried forward, if any. Deferred tax assets and liabilities are measured using tax rates expected to apply to taxable income in the years in which the applicable temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates or tax status is recognized in the statements of income in the period in which the change is identified. Deferred tax assets are reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The Company is subject to examination of its income tax returns by various tax authorities on a periodic basis. The Company regularly assesses the likelihood of adverse outcomes resulting from such examinations to determine the adequacy of its provision for income taxes. The Company has applied the provisions of the applicable accounting guidance on accounting for uncertainty in income taxes, which requires application of a more-likely-than-not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits the Company to recognize a tax benefit measured at the largest amount of tax benefit that, in the Company’s judgment, is more than 50% 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 of such change.

The Company files 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, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves and penalties, as well as the related interest, in light of changing facts and circumstances. Changes in the Company’s assessment of its uncertain tax positions or settlement of any particular position could materially and adversely impact the Company’s income tax rate, operating results, financial position and cash flows.

Recently Adopted Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures. This ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The Company adopted ASU 2023-09 on a prospective basis in the fourth quarter of fiscal 2025, which resulted in the inclusion of required additional disclosures in our consolidated financial statements. Refer to Note 11, “Income Taxes” for our updated presentation.

Recently Issued Accounting Pronouncement and Income Tax Legislation

New Accounting pronouncement Not Yet Adopted

In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures. The ASU requires entities to disclose specified information about certain expenses in the notes to the financial statements, including employee compensation. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027 with early adoption permitted. The Company is currently assessing the impact of this ASU on our consolidated financial statements and related disclosures.

From time to time, new accounting pronouncements are issued by the FASB, or other standards setting bodies, that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes the impact of recently issued standards that are not yet effective will not have a material impact on its consolidated financial position, results of operations and cash flows upon adoption.

Income Tax Legislation

On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act (“OBBBA”). The OBBBA adjusted a number of provisions affecting businesses including the immediate expensing of domestic research and development costs, limitations on deductions for interest expense, and accelerated fixed asset depreciation. As of December 31, 2025, we have recognized the tax effects of the OBBBA, which did not have a material impact on our consolidated financial statements.
