Accounting Policies [Abstract]
Description of Business, Basis of Presentation and Significant Accounting Policies	Note 1. Description of Business, Basis of Presentation and Significant Accounting Policies Description of Business Juniper Networks, Inc. (the “Company” or “Juniper”) designs, develops, and sells products and services for high-performance networks, to enable customers to build scalable, reliable, secure and cost-effective networks for their businesses, while achieving agility and improved operating efficiency through automation. Juniper challenges the inherent complexity that comes with networking in the multicloud era. Juniper does this with products, solutions and services that transform the way people connect, work and live. Juniper simplifies the process of transitioning to a secure and automated multicloud environment to enable secure, AI-driven networks that connect the world. Basis of Presentation The Consolidated Financial Statements, which include the Company and its wholly-owned subsidiaries, are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). All intercompany balances and transactions have been eliminated. Use of Estimates The preparation of the financial statements and related disclosures in accordance with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in the Consolidated Financial Statements and the accompanying notes. The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes are reasonable under the circumstances, to determine the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from these estimates. HPE Merger Agreement On January 9, 2024, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Hewlett Packard Enterprise Company, a Delaware corporation (“HPE”), and Jasmine Acquisition Sub, Inc., a Delaware corporation and wholly owned subsidiary of HPE (“Merger Sub”), pursuant to which Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of HPE. Under the terms of the Merger Agreement, at the effective time of the Merger, each issued and outstanding share of the Company's common stock (subject to certain exceptions set forth in the Merger Agreement) will be cancelled and converted into the right to receive $40.00 in cash, without interest and subject to applicable withholding taxes. On April 2, 2024, the Company received approval of the Merger Agreement from its stockholders. The Merger Agreement generally requires the Company to use commercially reasonable efforts to operate the Company's business in the ordinary course, subject to certain exceptions including as required by applicable law, pending consummation of the Merger, and subjects the Company to customary interim operating covenants that restrict the Company from taking certain specified actions without HPE’s approval (such approval not to be unreasonably withheld, conditioned, or delayed) until the Merger is completed or the Merger Agreement is terminated in accordance with its terms. During this period, the Company is permitted to continue paying regular quarterly dividends, substantially in accordance with past practice, at a quarterly rate not to exceed $0.22 per share. The completion of the Merger is subject to the receipt of regulatory approvals and other customary closing conditions. On January 30, 2025, the U.S. Department of Justice (the “DOJ”) filed a complaint seeking to enjoin the Merger and block the acquisition of Juniper by HPE. Both the Company and HPE have stated their disagreement with the DOJ’s concerns, and we remain fully committed to completing it. As of the date of this filing, we have received all required regulatory approvals and clearances from all applicable countries, other than the U.S. and Israel. If the transaction is consummated, the Company's common stock will be delisted from the New York Stock Exchange and deregistered under the Securities Exchange Act of 1934 (the “Exchange Act”). The Merger Agreement can be terminated under certain customary circumstances, including by mutual agreement, the imposition of a final and non-appealable governmental order that permanently enjoins or otherwise prohibits the Merger, an uncured breach of the Merger Agreement by the other party, or if the Merger has not been consummated by April 9, 2025, as may be automatically further extended pursuant to the terms of the Merger Agreement. Under certain specified circumstances in which the Merger Agreement is terminated, HPE is required to pay the Company a termination fee equal to $815.0 million . In connection with the pending Merger, the Company incurred $61.9 million and $1.6 million of expenses for the year ended December 31, 2024 and 2023, respectively, including professional services, financial advisory fees, and certain retention costs, all of which were recorded within “ Merger-related charges ” in the Consolidated Statements of Operations. Cash, Cash Equivalents, and Investments Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, demand deposits with banks, highly liquid investments in money market funds, commercial paper, government securities, certificates of deposits, time deposits, and corporate debt securities, which are readily convertible into cash. All highly liquid investments with original maturities of three months or less from Juniper's purchase date are classified as cash equivalents. Investments in Available-for-Sale Debt Securities The Company's investments in debt securities are classified as available-for-sale and include the Company's fixed income securities and investments in privately-held companies, consisting of debt and redeemable preferred stock securities. Fixed income securities primarily consist of corporate debt securities, U.S. treasury securities, time deposits, asset-backed and mortgage-backed securities, certificate of deposits, commercial paper, U.S. government agency securities, and foreign government debt securities. Fixed income securities are initially recorded at cost and periodically adjusted to fair value in the Consolidated Balance Sheets. The Company periodically evaluates these investments to determine if impairment charges are required. The Company determines whether a credit loss exists for available-for-sale debt securities in an unrealized loss position. When the fair value of a security is below its amortized cost, the amortized cost will be reduced to its fair value and the resulting loss will be recorded in Consolidated Statements of Operations, if it is more likely than not that we are required to sell the impaired security before recovery of its amortized cost basis, or we have the intention to sell the security. If neither of these conditions are met, the Company considers the extent to which the fair value is less than the amortized cost, any changes to the rating of the security by a rating agency, and review of the issuer's financial statements. If factors indicate a credit loss exists, an allowance for credit loss is recorded through other expense, net, limited by the amount that the fair value is less than the amortized cost basis. The Company's privately-held debt and redeemable preferred stock securities are included in other long-term assets in the Consolidated Balance Sheets and are recorded at fair value. In determining the estimated fair value of such securities, the Company utilizes the most recent data available for the investee including known acquisition offers and subsequent funding rounds. The Company periodically evaluates these securities for indicators of impairment, including the inability to recover a portion of or the entire carrying amount of the investment, the inability of the investee to sustain earnings, the reduction in or termination of financial commitment to the investee from other investors, the intention to sell the investment, and whether it is more likely than not that the Company will be required to sell the investment before recovery of the entire amortized cost basis. If the Company determines that the decline in an investment's value indicates credit losses, the difference is recognized as an impairment loss in its Consolidated Statements of Operations. For all available-for-sale debt securities, unrealized gains and the amount of unrealized loss relating to factors other than credit loss are reported as a separate component of accumulated other comprehensive loss in the Consolidated Balance Sheets. Realized gains and losses are determined based on the specific identification method and are reported in the Consolidated Statements of Operations. Investments in Equity Securities The Company's investments in equity securities with readily determinable fair values consist of money market funds, mutual funds, and an investment in a public company. These investments are measured at fair value with changes in fair value recognized in the Consolidated Statements of Operations. Equity securities without readily determinable fair values include the Company's investments in privately-held companies consisting of non-redeemable preferred stock and common stock securities. The Company accounts for these securities at cost, adjusted for changes from observable transactions for identical or similar investments of the same issuer, less impairments. Fair value of these equity securities is reassessed when the Company identifies observable price changes indicating that an adjustment upward or downward to the carrying value is necessary. Any observable changes in fair value are recognized in earnings as of the date that the observable transaction took place. In addition, the Company periodically evaluates equity securities without readily determinable fair values to determine if impairment charges are required by evaluating whether an event or change in circumstance has occurred that may have a significant adverse effect on the fair value of the investment. A qualitative assessment is performed each reporting period to assess whether there are any impairment indicators, including, but not limited to, significant deterioration in the investee's earnings performance; credit rating; asset quality or business prospects; adverse change in the regulatory, economic, or technological environment; change in the general market condition of the geographic area or industry; acquisition offers; and the ability to continue as a going concern. If such indicators are present, the Company estimates the fair value of impaired investments and recognizes an impairment loss in the Consolidated Statement of Operations equal to the difference between the carrying value and fair value. The Company accounts for investments in companies over which it has the ability to exercise significant influence, but does not have control over the investee, under the equity method of accounting. The investment is initially measured at fair value and subsequently adjusted for any impairment, investee capital transactions, dividend received, plus or minus the Company's proportionate share of the equity method investee's income or loss. The Company records its interest in the net earnings or loss of its equity method investment along with adjustments for unrealized profits or losses on intra-entity transactions, within its Consolidated Statements of Operations. Depending on the timing of such financial statements of the investee, there may be a lag between the timing of such financial statement and the Company's quarter-end date. For the Company's sole equity method investment, the Company's share of the investee's net earnings or loss is recorded two months in arrears. The Company records an impairment when factors indicate that the carrying amount of the investment might not be recoverable. In December 2024, the Company sold its investment accounted for under the equity method of accounting. Refer to Note 2, Cash Equivalents and Investments. Fair Value Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, the Company considers the principal or most advantageous market in which it transacts, and considers assumptions that market participants would use when pricing the asset or liability. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. These inputs are valued using market-based approaches. Level 3 – Inputs are unobservable inputs based on the Company’s assumptions. These inputs, if any, are valued using internal financial models. Derivative Instruments The Company uses derivative instruments, primarily foreign currency forward and interest rate contracts, to hedge certain foreign currency and interest rate exposures. The Company does not enter into derivatives for speculative or trading purposes. The Company uses foreign currency forward contracts or options contracts to hedge certain forecasted foreign currency transactions relating to operating expenses. These derivatives are designated as cash flow hedges, which are carried at fair value with the derivative's gain or loss initially reported as a component of accumulated other comprehensive loss, and upon occurrence of the forecasted transaction, is subsequently reclassified into the costs of services or operating expense line item to which the hedged transaction relates. Cash flows from such hedges are classified as operating activities. The Company also uses foreign currency forward contracts to mitigate variability in gains and losses generated from the re-measurement of certain monetary assets and liabilities denominated in non-functional currencies. These derivatives are carried at fair value with changes recorded in other expense, net in the Consolidated Statements of Operations in the same period as the changes in the fair value from the re-measurement of the underlying assets and liabilities. Cash flows from such derivatives are classified as operating activities. The Company uses interest rate swap contracts to convert certain of our fixed interest rate notes to floating interest rates based on the Secured Overnight Financing Rate (SOFR). All interest rate swap contracts will expire within seven years. The change in fair value of the derivative instrument substantially offsets the change in the fair value of the hedged item. These derivatives are classified in the Consolidated Statements of Cash Flows in the same section as the underlying item. The Company uses interest rate lock contracts, which fix the benchmark interest rates of future debt issuance. The Company records changes in fair value of these contracts in accumulated other comprehensive income (loss) in the Consolidated Balance Sheets, in the period of change. When the forecasted transaction occurs, the Company will start to amortize the accumulated gains or losses included as a component of other comprehensive income (loss) related to the interest rate lock cash flow hedges to interest expense. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, the gains or losses on the related cash flow hedge from accumulated other comprehensive income (loss) will be reclassified to other income and expense within the income statement. During the year ended December 31, 2024 , the Company terminated these interest rate lock contracts. Refer to Note 4, Derivative Instruments . The Company presents its derivative assets and derivative liabilities on a gross basis in the Consolidated Balance Sheets. However, under agreements containing provisions on set-off with certain counterparties, subject to applicable requirements, the Company is allowed to net-settle transactions, with a single net amount payable by one party to the other. The Company is neither required to pledge nor entitled to receive cash collateral related to these derivative transactions. Inventory Inventory consists primarily of component parts to be used in the manufacturing process and finished goods, and is stated at the lower of cost or net realizable value. In addition, the Company purchases and holds inventory to provide adequate component supplies over the life of the underlying products. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. A charge is recorded to cost of product when inventory is determined to be in excess of anticipated demand or considered obsolete. At the point of loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in the newly established cost basis. Leases The Company determines if an arrangement is a lease at inception. The Company evaluates classification of leases as either operating or finance at commencement and, as necessary, at modification. As of December 31, 2024, the Company did not have any finance leases. Operating leases are included in operating lease right-of-use ("ROU") assets, other accrued liabilities, and operating lease liabilities on the Company's Consolidated Balance Sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized on the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made prior to lease commencement and excludes lease incentives. Variable lease payments not dependent on an index or a rate, are expensed as incurred and are not included within the ROU asset and lease liability calculation. Variable lease payments primarily include reimbursements of costs incurred by lessors for common area maintenance and utilities. The Company's lease terms are the noncancelable period, including any rent-free periods provided by the lessor, and include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. At lease inception, and in subsequent periods as necessary, the Company estimates the lease term based on its assessment of extension and termination options that are reasonably certain to be exercised. Lease costs are recognized on a straight-line basis over the lease term. The Company does not separate non-lease components from lease components for all underlying classes of assets. In addition, the Company does not recognize ROU assets and lease liabilities for short-term leases, which have a lease term of twelve months or less and do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. Lease cost for short-term leases is recognized on a straight-line basis over the lease term. Property and Equipment Property and equipment are recorded at cost less accumulated depreciation. Depreciation is calculated using the straight-line method, over the estimated useful lives of the following assets: Estimated Useful Life (years) Computers, equipment, and software 1.5 to 10 Furniture and fixtures 5 to 7 Building and building improvements 7 to 40 Land improvements 10 to 40 Leasehold improvements Lease term, not to exceed 10 years Land is not depreciated. Construction-in-process is related to the construction or development of property and equipment that have not yet been placed in service for their intended use. Business Combinations The purchase price of an acquired entity is allocated to tangible assets, liabilities, and intangible assets based on their estimated fair values with the residual of the purchase price recorded as goodwill. The determination of the value of the intangible assets acquired involves certain estimates, such as expected future cash flows, which include consideration of future growth rates and margins, attrition rates, future changes in technology, discount rates, and the expected use of the acquired assets. These factors are also considered in determining the useful life of the acquired intangible assets. Acquisition related expenses are recognized separately from the business combination and are expensed as incurred. The Company's Consolidated Financial Statements include the operating results of acquired businesses from the date of each acquisition. Goodwill and Intangible Assets Goodwill is tested for impairment annually on November 1 or more frequently if certain circumstances indicate the carrying value of goodwill is impaired. Goodwill is tested for impairment at the reporting unit level. A qualitative assessment is first performed to determine whether it is necessary to quantitatively test goodwill for impairment. This initial assessment includes, among others, consideration of macroeconomic conditions and financial performance. If the qualitative assessment indicates that it is more likely than not that an impairment exists, a quantitative analysis is performed by determining the fair value of the reporting unit using a combination of the discounted cash flow and the market approaches. Goodwill is considered impaired if the carrying value of the reporting unit exceeds its fair value. A goodwill impairment loss is recognized for the amount that the carrying amount of the reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. Intangible assets consist of existing technology, customer relationships, and trade name, which are amortized over the period of estimated benefit using the straight-line method and estimated useful lives of 4 or 5 years. Impairment of Long-lived Assets Long-lived assets, such as property, plant, and equipment, ROU assets, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group, to estimated undiscounted future cash flows expected to be generated by the asset, or asset group. An impairment charge is recognized by the amount by which the carrying amount of the asset, or asset group, exceeds its fair value. Warranty Reserves The Company generally offers a one-year warranty or limited life-time warranty on most of its hardware products, and a 90-day warranty on the media that contains the software embedded in the products. Warranty costs are recognized as part of the Company's cost of sales based on associated material costs, logistics costs, labor costs, and overhead at the time revenue is recognized. Material costs are estimated primarily based upon the historical costs to repair or replace product returns within the warranty period. Labor, logistics, and overhead costs are estimated primarily based upon historical trends in the cost to support customer cases within the warranty period. Warranty reserve is reported within other accrued liabilities in the Consolidated Balance Sheets. Contract Manufacturer Liabilities The Company establishes a liability for non-cancelable, non-returnable purchase commitments with its contract manufacturers for carrying charges, quantities in excess of its demand forecasts, or obsolete material charges for components purchased by the contract manufacturers to meet the Company’s demand forecast or customer orders. The demand forecasts are based upon historical trends and analysis, adjusted for overall market conditions. Loss Contingencies The Company is subject to the possibility of various loss contingencies arising in the ordinary course of business. Management considers the likelihood of loss related to the occurrence of a liability as well as its ability to reasonably estimate the amount of loss, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company regularly evaluates current information available to determine whether such accruals should be adjusted and whether new accruals are required. Foreign Currency Assets and liabilities of foreign operations with non-U.S. Dollar functional currency are translated to U.S. Dollars using exchange rates in effect at the end of the period. Revenue and expenses are translated to U.S. Dollars using rates that approximate those in effect during the period. The resulting translation adjustments are included in the Company’s Consolidated Balance Sheets in the stockholders’ equity section as a component of accumulated other comprehensive loss. The Company remeasures monetary assets and monetary liabilities in non-functional currencies and records the resulting foreign exchange transaction gains and losses in other expense, net in the Consolidated Statements of Operations. Revenue Recognition Revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services by following a five-step process, (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price, and (5) recognize revenue when or as the Company satisfies a performance obligation, as further described below. Identify the contract with a customer . The Company generally considers a sales contract and/or agreement with an approved purchase order as a customer contract provided that collection is considered probable, which is assessed based on the creditworthiness of the customer as determined by credit checks, payment histories, and/or other circumstances. The Company combines contracts with a customer if contracts are negotiated with a single commercial substance or contain price dependencies. Identify the performance obligations in the contract . Product performance obligations include hardware, software licenses including perpetual and term-based licenses, and service performance obligations including maintenance services, Software-as-a-Service ("SaaS"), education and training, and professional services. Determine the transaction price . The transaction price for the Company’s contracts with its customers consists of both fixed and variable consideration, provided it is probable that a significant reversal of revenue will not occur when the uncertainty related to variable consideration is resolved. Fixed consideration includes amounts to be contractually billed to the customer while variable consideration includes estimates for rights of return, rebates, and price protection, which are based on historical sales returns and price protection credits, specific criteria outlined in rebate agreements, and other factors known at the time. The Company generally invoices customers for hardware, software licenses and related maintenance arrangements at time of delivery, and professional services either upfront or upon meeting certain milestones. Customer invoices are generally due within 30 to 90 days after issuance. The Company’s contracts with customers typically do not include significant financing components as the period between the transfer of performance obligations and timing of payment are generally within one year. Allocate the transaction price to the performance obligations in the contract . For contracts that contain multiple performance obligations, the Company allocates the transaction price to the performance obligations on a relative stand-alone selling price ("SSP") basis. SSP is based on multiple factors including, but not limited to historical discounting trends for products and services, pricing practices in different geographies and through different sales channels, gross margin objectives, internal costs, competitor pricing strategies, and industry technology lifecycles. Recognize revenue when or as the Company satisfies a performance obligation . Revenue for hardware and certain software licenses, are recognized at a point in time, which is generally upon shipment or delivery. Certain software licenses are recognized on a ratable basis over the term of the license. Revenue for maintenance services and SaaS is recognized on a ratable basis over the contract term. Revenue from education, training, and professional services is recognized as services are completed or ratably over the contractual period of generally one year or less. Deferred product revenue represents unrecognized revenue related to undelivered product commitments and other shipments that have not met revenue recognition criteria. Deferred service revenue represents billed amounts for service contracts, which include technical support, hardware and software maintenance, professional services, SaaS, and education and training, for which services have not been rendered. Revenue is recognized net of any taxes collected, which are subsequently remitted to governmental authorities. Deferred Contract Costs Sales commissions earned by the Company’s sales force are considered incremental and recoverable costs of obtaining a contract with a customer. The Company capitalizes these costs, for which the transfer of the goods or services to which the asset relates will occur in future periods. These costs are recorded as prepaid expenses or other long-term assets and are deferred and then amortized over a period of benefit which is typically over the term of the customer contracts. Amortization expense is included in sales and marketing expenses in the accompanying Consolidated Statements of Operations. Research and Development Costs to research, design, and develop the Company's products are expensed as incurred. Software Development Costs Capitalization of software development costs for software to be sold, leased, or otherwise marketed begins when a product's technological feasibility has been established and ends when a product is available for general release to customers. Generally, the Company's products are released soon after technological feasibility has been established. As a result, costs incurred between achieving technological feasibility and product general availability have not been significant. The Company capitalizes costs associated with internal-use software systems during the application development stage. Such capitalized costs include external direct costs incurred in developing or obtaining the applications and payroll and payroll-related costs for employees, who are directly associated with the development of the applications. Advertising Advertising costs are charged to sales and marketing expense as incurred. Costs to produce advertising were approximately $3.9 million, $4.9 million, and $7.4 million for 2024, 2023 and 2022, respectively. Costs to communicate advertising totaled approximately $13.3 million, $25.9 million, and $30.0 million, for 2024, 2023, and 2022, respectively. Share-Based Compensation The Company measures and recognizes compensation cost for all share-based awards made to employees and directors, including employee stock options, restricted stock awards ("RSAs"), restricted stock units ("RSUs"), performance share awards ("PSAs") and employee stock purchases related to the Employee Stock Purchase Plan ("ESPP"). For service condition only awards, share-based compensation expense is based on the fair value of the underlying awards and amortized on a straight-line basis. For PSAs, share-based compensation expense is amortized on a straight-line basis for each separate vesting portion of the awards. The Company accounts for forfeitures as they occur. The Company utilizes

Cash Equivalents and Investments Investments in Available-for-Sale Debt Securities The following table summarizes the Company's unrealized gains and losses and fair value of investments designated as available-for-sale debt securities as of December 31, 2024 and December 31, 2023 (in millions): As of December 31, 2024 As of December 31, 2023 Amortized Gross Unrealized Gross Unrealized and Credit Losses Estimated Fair Amortized Gross Unrealized Gross Unrealized and Credit Losses Estimated Fair Fixed income securities: Asset-backed and mortgage-backed securities $ 106.6 $ 0.4 $ (0.5) $ 106.5 $ 38.2 $ 0.2 $ (0.4) $ 38.0 Certificates of deposit 6.8 — — 6.8 3.0 — — 3.0 Commercial paper 77.2 — — 77.2 41.1 — — 41.1 Corporate debt securities 308.8 0.9 (0.3) 309.4 160.2 0.7 (1.3) 159.6 Foreign government debt securities — — — — 5.3 — (0.2) 5.1 Time deposits 202.2 — — 202.2 273.6 — — 273.6 U.S. government agency securities 6.0 — — 6.0 4.0 — — 4.0 U.S. government securities 99.2 0.1 — 99.3 54.8 0.1 — 54.9 Total fixed income securities 806.8 1.4 (0.8) 807.4 580.2 1.0 (1.9) 579.3 Privately-held debt and redeemable preferred stock securities 45.8 — (15.4) 30.4 20.6 37.4 (8.3) 49.7 Total available-for-sale debt securities $ 852.6 $ 1.4 $ (16.2) $ 837.8 $ 600.8 $ 38.4 $ (10.2) $ 629.0 Reported as: Cash equivalents $ 273.9 $ — $ — $ 273.9 $ 328.2 $ — $ — $ 328.2 Short-term investments 147.9 0.2 — 148.1 135.7 — (1.4) 134.3 Long-term investments 385.0 1.2 (0.8) 385.4 116.3 1.0 (0.5) 116.8 Other long-term assets 45.8 — (15.4) 30.4 20.6 37.4 (8.3) 49.7 Total $ 852.6 $ 1.4 $ (16.2) $ 837.8 $ 600.8 $ 38.4 $ (10.2) $ 629.0 The following table presents the contractual maturities of the Company's total fixed income securities as of December 31, 2024 (in millions): Amortized Estimated Fair Due in less than one year $ 421.8 $ 422.0 Due between one and five years 385.0 385.4 Total $ 806.8 $ 807.4 As of December 31, 2024, the Company had an unrea lized loss of $0.8 million from 72 fixed income available-for-sale debt securities, of which $0.6 million was from investments in an unrealized loss position for less than 12 months, and $0.2 million was from investments in an unrealized loss position for more than 12 months. The gross unrealized losses related to these investments were primarily due to changes in market interest rates. The Company anticipates that it will recover the entire amortized cost basis of such available-for-sale debt securities and has determined that no allowance for credit losses was required to be recognized during the years ended December 31, 2024 and December 31, 2023. During the years ended December 31, 2024 and December 31, 2023, the Company recognized an allowance for credit loss of $7.1 million and $8.3 million, respectively, on privately-held debt and redeemable preferred stock investments. During the year ended December 31, 2022, there were no credit losses related to the Company's privately-held debt and redeemable preferred stock investments. As of December 31, 2024 and 2023, the Company had an allowance for credit loss of $15.4 million and $8.3 million, respectively, on its privately-held debt and redeemable preferred stock investments. The credit loss represents the difference between the estimated fair value and the cost of the investment related to the credit factors. The determination of fair value was based on quantitative and qualitative analysis including factors such as the near-term prospects of the investee in the market in which it operates and evaluating the investee’s financial condition in relation to its outstanding obligations. During the years ended December 31, 2024, 2023, and 2022, the Company had no material gross realized gains or losses from available-for-sale debt securities. Investments in Equity Securities The following table presents the Company's investments in equity securities as of December 31, 2024 and 2023 (in millions): As of December 31, 2024 2023 Equity investments with readily determinable fair value Money market funds $ 562.6 $ 337.5 Mutual funds 49.1 38.0 Publicly-traded equity securities 12.2 5.1 Equity investments without readily determinable fair value 53.8 45.8 Equity investment under the equity method of accounting — 26.4 Total equity securities $ 677.7 $ 452.8 Reported as: Cash equivalents $ 562.6 $ 337.5 Short-term investments 12.2 5.1 Prepaid expenses and other current assets 3.5 2.5 Other long-term assets 99.4 107.7 Total $ 677.7 $ 452.8 During the years ended December 31, 2024, 2023, and 2022, there were no material unrealized gains or losses recognized for equity investments with readily determinable fair values or equity investments without readily determinable fair value except for $89.9 million of unrealized losses recognized for equity securities without readily determinable fair value during the year ended December 31, 2023. The unrealized losses represent the difference between the estimated fair values and the carrying values of equity investments without readily determinable fair value. The Company estimated the fair value of these investments based on quantitative and qualitative analysis. This analysis involved use of judgment, significant estimates and assumptions, such as the near-term prospects of the investee in the market in which it operates, evaluating the investee’s financial condition in relation to its outstanding obligations, and probabilities of securing additional capital through various alternative scenarios. During the year ended December 31, 2024, we sold our entire investment accounted for under the equity method of accounting for $30.0 million and recorded a gain of $13.2 million within "Gain (loss) on privately-held investments, net" in the Consolidated Statement of Operations. As of December 31, 2023, the Company's ownership in the investment accounted for under the equity method of accounting represented approximately 24.1%. During the years ended December 31, 2024, 2023 and 2022, the loss recognized from the Company's share of the equity method investment's profit and loss was $9.6 million, $9.6 million and $4.8 million, respectively. Restricted Cash and Investments The Company has restricted cash and investments for: (i) amounts under the Company's non-qualified deferred compensation plan for senior-level employees; (ii) amounts held under the Company's short-term disability plan in California; and (iii) amounts held in escrow accounts, as required in connection with certain acquisitions. Restricted investments consist of equity investments. As of December 31, 2024, the carrying value of restricted cash and investments was $60.6 million, of which $12.6 million was included in prepaid expenses and other current assets and $48.0 million was included in other long-term assets on the Consolidated Balance Sheets. The following table provides a reconciliation of cash, cash equivalents, and restricted cash included in the Consolidated Balance Sheets as of December 31, 2024 and December 31, 2023 (in millions): As of December 31, 2024 2023 Cash and cash equivalents $ 1,224.3 $ 1,068.1 Restricted cash included in Prepaid expenses and other current assets 9.2 13.8 Restricted cash included in Other long-term assets 2.3 2.4 Total cash, cash equivalents, and restricted cash $ 1,235.8 $ 1,084.3

The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes, or alternative pricing sources with reasonable levels of price transparency which are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets. The Company's derivative instruments are classified as Level 2, as they are not actively traded and are valued using pricing models that use observable market inputs. During the years ended December 31, 2024 and 2023, the Company had no transfers into or out of Level 3 of the fair value hierarchy of its assets or liabilities measured at fair value. The Company's privately-held debt and redeemable preferred stock securities are classified as Level 3 assets due to the lack of observable inputs to determine fair value. The Company estimates the fair value of its privately-held debt and redeemable preferred stock securities on a recurring basis using an analysis of the financial condition and near-term prospects of the investee, including recent valuations at the time of financing activities and the investee's capital structure. During 2024, the Company invested in a convertible note of a privately-held company for a principal amount of $25.0 million with a maturity of two years. During the year ended December 31, 2024, the Company recognized a credit loss of $7.1 million on its privately-held debt and redeemable preferred stock securities. Refer to Note 2, Cash Equivalents and Investments. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The Company's investments in equity securities without readily determinable fair value are classified as Level 3 assets due to the lack of observable inputs to determine fair value. The Company estimates the fair value of equity securities without readily determinable fair value and investments accounted for under the equity method of accounting, on a nonrecurring basis using an analysis of the financial condition and near-term prospects of the investee, including recent financing activities and the investee's capital structure. As of December 31, 2024, cumulative impairments and downward adjustments for equity securities without readily determinable fair value were $89.9 million.

As of December 31, 2024 and December 31, 2023, the potential effects of set-off associated with the derivative contracts would be a reduction to both derivative assets and derivative liabilities b y $1.1 million and $7.2 million, respectively. Designated Derivatives The Company uses foreign currency forward contracts or options contracts to hedge the Company's planned cost of revenues and operating expenses denominated in foreign currencies. These derivatives are designated as cash flow hedges and have maturities of twelve months or less. The Company enters into interest rate swap contracts, designated as fair value hedges, to convert the fixed interest rates of certain Senior Notes ("Notes") to floating interest rates. In April 2021, the Company entered into these contracts for an aggregate notional amount of $300.0 million for its fixed-rate Notes maturing in December 2030 in addition to the contracts entered in 2019 for an aggregate notional amount of $300.0 million for its fixed-rate Notes maturing in March 2041. The interest rate swap contracts will expire within six years. In 2020, the Company entered into interest rate lock contracts with large financial institutions, which fix the benchmark interest rates of future debt issuances for an aggregate notional amount of $650.0 million. These contracts were designated as cash flow hedges for a forecasted debt issuance which was expected to occur by the end of 2025 . During the year ended December 31, 2023 , the Company terminated the interest rate lock contracts, resulting in a deferred gain of $133.9 million recognized in accumulated other comprehensive income, which will be deferred and amortized to interest expense over the term of the anticipated debt unless it becomes probable that the debt will not be issued with the terms anticipated at the hedge's inception. The Company classifies the cash flow in the same section as the underlying item resulting in the proceeds from sale being presented as operating activities. Effect of Derivative Instruments on the Consolidated Statements of Operations For cash flow hedges, the Company recognized an unrealized loss of $17.3 million , unrealized gain of $15.1 million and unrealized gain of $33.1 million in accumulated other comprehensive loss for the effective portion of its derivative instruments during the years ended December 31, 2024, 2023, and 2022, respectively. For foreign currency contracts, the Company reclassified a loss of $6.3 million, $29.8 million and $25.8 million out of accumulated other comprehensive loss to cost of revenues and operating expenses in the Consolidated Statements of Operations during the years ended December 31, 2024, 2023, and 2022, respectively. As of December 31, 2024, an estimated $10.9 million of unrealized net loss within accumulated other comprehensive income is expected to be reclassified into earnings within the next twelve months. Non-Designated Derivatives The Company also uses foreign currency forward contracts to mitigate variability in gains and losses generated from the remeasurement of certain monetary assets and liabilities denominated in foreign currencies. These foreign exchange forward contracts typically have maturities of approximately one The outstanding non-designated derivative instruments are carried at fair value. Changes in the fair value of these derivatives, which were recorded in Other expense, net within the Consolidated Statements of Operations, were not material during the years ended December 31, 2024, 2023, and 2022, respectively.

Restructuring Charges	Note 7. Restructuring Charges The Company’s restructuring events are primarily intended to realign its workforce, optimize cost structure, and consolidate facilities as a result of organizational and leadership changes to effectively support the Company’s long-term strategic objectives. Restructuring charges include termination benefits related to workforce reductions, facility exit-related costs, contract termination costs, impairment of certain assets and other related costs associated with exit or disposal activities. Workforce reduction-related benefits are provided to employees primarily under the Company’s ongoing benefit arrangements, which are accrued when the existing situation or set of circumstances indicates that an obligation has been incurred, it is probable the benefits will be paid, and the amount can be reasonably estimated in accordance with the provisions of the applicable accounting guidance.

These contracts convert the fixed interest rates of certain Notes to floating interest rates and are designated as fair value hedges. See Note 4, Derivative Instruments , for a discussion of the Company's interest rate swap contracts. The Notes above are the Company’s senior unsecured and unsubordinated obligations, ranking equally in right of payment to all of the Company’s existing and future senior unsecured and unsubordinated indebtedness, and senior in right of payment to any of the Company’s future indebtedness that is expressly subordinated to the Notes. As of December 31, 2024, the Company's aggregate debt maturities based on outstanding principal were as follows (in millions): Years Ending December 31, Amount 2025 $ 400.0 2026 — 2027 — 2028 — 2029 500.0 Thereafter 800.0 Total $ 1,700.0 The Company may redeem the Notes, either in whole or in part, at any time at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the Notes to be redeemed or (ii) the sum of the present values of the remaining scheduled payments discounted to the redemption date, plus, in either case, accrued and unpaid interest, if any. In the event of a change of control repurchase event, the holders of the Notes may require the Company to repurchase for cash all or part of the Notes at a purchase price equal to 101% of the aggregate principal amount, plus accrued and unpaid interest, if any. Interest on the Notes is payable in cash semiannually. The effective interest rates for the Notes include the interest on the Notes, accretion of the discount, and amortization of issuance costs. The indenture and supplemental indentures (together, the "indentures") that govern the Notes also contain various covenants, including limitations on the Company's ability to incur liens or enter into sale-leaseback transactions over certain dollar thresholds. As of December 31, 2024, the Company was in compliance with all covenants in the indentures governing the Notes. Revolving Credit Facility In June 2023, the Company entered into a credit agreement with certain institutional lenders that provides for a five-year $500.0 million unsecured revolving credit facility (the "Revolving Credit Facility"), with an option to increase the Revolving Credit Facility by up to an additional $200.0 million, subject to the lenders' approval. Proceeds of loans made under the Revolving Credit Facility may be used by the Company for general corporate purposes. The Revolving Credit Facility will terminate in June 2028, subject to two one-year maturity extension options, on the terms and conditions set forth in the credit agreement. Revolving loans will bear interest, at the Company’s option, at either (i) a per annum rate equal to (x) with respect to borrowings in U.S. dollars, the adjusted term Secured Overnight Financing Rate ("SOFR"), (y) with respect to borrowings in Euros, the adjusted Euro Interbank Offered Rate ("EURIBOR"), and (z) with respect to borrowings in pounds sterling, daily simple Sterling Overnight Index Average ("SONIA"), in each case, plus a margin of between 0.875% and 1.500%, depending on the Company’s public debt rating, or (ii) with respect to borrowings in U.S. dollars, a per annum rate equal to the Base Rate plus a margin of between 0.000% and 0.500%, depending on the Company’s public debt rating. Base Rate is defined as the greatest of (A) the Wall Street Journal prime rate, (B) the greater of the U.S. federal funds rate and the overnight bank funding rate plus 0.500% and (C) the adjusted term SOFR for a period of one month plus 1.00%. The Revolving Credit Facility also requires payment of a commitment fee on undrawn amounts at a rate of 0.075% to 0.225%, depending on the Company’s public debt rating. The Revolving Credit Facility requires the Company to maintain a leverage ratio no greater than 3.0x (provided that if a material acquisition has been consummated, the Company is permitted to maintain a leverage ratio no greater than 3.5x for up to four quarters). As of December 31, 2024, no amounts were outstanding under the Revolving Credit Facility and the Company was in compliance with all covenants in the Credit Agreement. Financing Arrangements The Company provides certain customers with access to extended financing arrangements that allow for longer payment terms than those typically provided by the Company by factoring accounts receivable to third-party financing providers ("financing providers"). The program does not and is not intended to affect the timing of the Company's revenue recognition. Under the financing arrangements, proceeds from the financing providers are due to the Company within 1 to 90 days from the sale of the receivable. In these transactions with the financing providers, the Company surrenders control over the transferred assets. Pursuant to the financing arrangements for the sale of receivables, the Company sold receivables of $13.3 million, $37.4 million and $50.6 million during the years ended December 31, 2024, 2023, and 2022, respectively.

Segment Reporting [Abstract]
Segments	Note 11. Segments The Company's chief executive officer, who is the chief operating decision maker ("CODM"), reviews discrete financial information presented at the consolidated basis, to assess performance and allocate resources. There are no segment managers who are held accountable for operations or operating results below the consolidated unit level. Accordingly, the Company operates in one reportable segment. The CODM uses net income, which is a measure of profit or loss that is also reported on the Consolidated Statement of Operations as consolidated net income, to decide whether to reinvest profits into the business or invest into other parts of the entity. It is further accompanied by disaggregated information about net revenues by customer solution, customer vertical, and geographic region as presented below.

In 2023, within "Other", the Company recorded a tax expense of $9.8 million on adjustments for certain privately-held investments and $5.0 million related to interest on income tax reserves. This was partially offset by income tax benefits of $10.9 million due to changes in tax legislation. Deferred income taxes reflect the net tax effects of tax carry-forward items and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred income taxes are classified as other long-term assets in the Company's Consolidated Balance Sheets. Significant components of the Company's long-term deferred tax assets and deferred tax liabilities are as follows (in millions): As of December 31, 2024 2023 Deferred tax assets: Net operating loss carry-forwards $ 32.2 $ 44.4 Research and other credit carry-forwards 295.8 294.4 Deferred revenue 131.5 74.9 Share-based compensation 20.7 25.4 Capitalized R&D expenditure 624.7 475.7 Reserves and accruals not currently deductible 140.0 133.0 Operating lease liabilities 43.2 31.9 Other 13.0 12.1 Total deferred tax assets 1,301.1 1,091.8 Valuation allowance (331.2) (326.9) Deferred tax assets, net of valuation allowance 969.9 764.9 Deferred tax liabilities: Property and equipment basis differences (0.1) (5.5) Purchased intangible assets (14.4) (23.0) Unremitted foreign earnings (24.1) (24.1) Net unrealized gain (30.9) (41.9) Operating lease assets (38.0) (29.5) Total deferred tax liabilities (107.5) (124.0) Net deferred tax assets $ 862.4 $ 640.9 As of December 31, 2024 and 2023, the Company had a valuation allowance on its U.S. and foreign deferred tax assets of $331.2 million and $326.9 million, respectively. The balance at December 31, 2024 consisted of $8.3 million, $318.7 million, and $4.2 million against the Company's U.S. federal, state, and foreign deferred tax assets, respectively, which the Company believes are not more likely than not to be utilized in future years. The valuation allowance increased in 2024 and 2023 by $4.3 million and $16 million, respectively, primarily related to changes in state R&D tax credits. As of December 31, 2024, the Company had federal, California and other states net operating loss carry-forwards of approximately $62.9 million, $128.7 million, and $93.7 million, respectively. The California net operating loss carry-forwards of $128.7 million are expected to expire unused. The Company also had federal, California, and other state tax credit carry-forwards of approximately $2.4 million, $330.1 million, and $31.3 million, respectively. Unused net operating loss and other state tax credit carry-forwards will expire at various dates beginning in the year 2025. The California tax credit carry-forwards will carry forward indefinitely. The Company provides deferred tax liabilities for all tax consequences associated with the undistributed earnings that are expected to be repatriated to subsidiaries' parent unless the subsidiaries' earnings are considered indefinitely reinvested. The Company has made no provision for deferred taxes on approximately $237.1 million of cumulative undistributed earnings of certain foreign subsidiaries through December 31, 2024. These earnings are considered indefinitely invested in operations of the subsidiaries, as the Company intends to utilize these amounts to fund future expansion of its operations. If these earnings were distributed to the parent, the Company would be subject to additional taxes of approximately $48.2 million. As of December 31, 2024, 2023, and 2022, the total amount of gross unrecognized tax benefits was $117.5 million, $132.8 million, and $116.0 million, respectively. As of December 31, 2024, approximately $112.5 million of the gross unrecognized tax benefits, if recognized, would affect the effective tax rate before considering valuation allowance. A reconciliation of the beginning and ending amount of the Company's total gross unrecognized tax benefits was as follows (in millions): Years Ended December 31, 2024 2023 2022 Balance at beginning of year $ 132.8 $ 116.0 $ 113.4 Tax positions related to current year: Additions 3.1 8.9 5.8 Tax positions related to prior years: Additions 6.1 8.9 6.9 Reductions (0.4) — (2.5) Settlements (22.7) — — Lapses in statutes of limitations (1.4) (1.0) (7.6) Balance at end of year $ 117.5 $ 132.8 $ 116.0 As of December 31, 2024, 2023, and 2022, the Company had accrued interest and penalties related to unrecognized tax benefits of $10.4 million, $12.0 million, and $5.6 million, respectively, as other long-term liabilities in the Consolidated Balance Sheets. Due to the changes in the level of gross unrecognized tax benefits, the Company recognized a (benefit), or expense, for net interest and penalties of $(1.6) million, $6.3 million, and $(2.5) million in its Consolidated Statements of Operations during the years ended December 31, 2024, 2023, and 2022, respectively. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense. The Company engages in continuous discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. There is a greater than remote likelihood that the balance of the gross unrecognized tax benefits will decrease by up to $52.4 million within the next twelve months due to the completion of tax review cycles in various tax jurisdictions and lapses of applicable statutes of limitation. The Company conducts business globally and, as a result, Juniper Networks or one or more of its subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world, including such jurisdictions as the Netherlands, U.K., France, Germany, Japan, China, Australia, India, and the U.S. With few exceptions, the Company is no longer subject to U.S. federal, state and local, and non-U.S. income tax examinations for years before 2012. The Company's examination by the Internal Revenue Service for the 2017 through 2018 tax years closed in February 2024. The closure did not have a significant impact to the income tax provision and the Company is not currently under examination by the IRS for other tax years. The Company is under examination by the India tax authorities for the 2012 through 2021 tax years, respectively. The Company regularly assesses the likelihood of an adverse outcome resulting from such examinations. As of December 31, 2024, the Company believes the resolution of the audits is unlikely to have a material effect on its consolidated financial condition or results of operations. The Company is pursuing all available administrative remedies relative to ongoing matters. The Company believes that it has adequately provided for any reasonably foreseeable outcomes related to proposed adjustments and the ultimate resolution of these matters is unlikely to have a material effect on its consolidated financial condition or results of operations; however, there is still a possibility that an adverse outcome of these matters could have a material effect on its consolidated financial condition and results of operations.

Diluted net income per share is computed using net income available to common stockholders and the weighted-average number of common shares outstanding plus potentially dilutive common shares outstanding during the period. Dilutive potential common shares consist of common shares issuable upon exercise of stock options and purchase rights, and vesting of RSUs, RSAs, and PSAs. The Company includes the common shares underlying PSAs in the calculation of diluted net income per share only when they become contingently issuable. Anti-dilutive shares are excluded from the computation of diluted net income per share.

Commitments and Contingencies	Note 14. Commitments and Contingencies Commitments Unconditional purchase obligations consist of agreements that include firm and non-cancelable terms to transfer funds in the future for fixed or minimum amounts or quantities to be purchased at fixed or minimum prices. For obligations with cancellation provisions, the amounts included in the following tables were limited to the non-cancelable portion of the agreement terms or the minimum cancellation fee. Purchase Commitments with Contract Manufacturers and Suppliers In order to reduce manufacturing lead times and in the interest of having access to adequate component supply, the Company enters into agreements with contract manufacturers and certain suppliers to procure inventory based on the Company's requirements. A significant portion of the Company's purchase commitments arising from these agreements consists of firm and non-cancelable commitments. In certain instances, these agreements allow the Company the option to cancel, reschedule, and adjust its requirements based on the Company's business needs prior to firm orders being placed. The following table summarizes the Company’s purchase commitments as of December 31, 2024 (in millions): Years Ending December 31, Purchase Commitments 2025 $ 864.7 2026 23.6 Total $ 888.3 The Company establishes a liability in connection with purchase commitments related to quantities in excess of its demand forecasts or obsolete materials charges for components purchased by the contract manufacturers based on the Company’s demand forecast or customer orders. As of December 31, 2024, the Company had accrued $19.5 million related to such charges. Other Purchase Obligations The following table summarizes the Company’s unconditional purchase obligations other than with contract manufacturers and suppliers as of December 31, 2024 (in millions): Years Ending December 31, Unconditional Purchase Obligations 2025 $ 76.1 2026 32.2 2027 7.0 2028 0.2 Total $ 115.5 Leases The Company leases its facilities and certain equipment under non-cancelable operating leases that have remaining lease terms of 1 to 12 years and 1 to 5 years, respectively. Each leased facility is subject to an individual lease or sublease, which could provide various options to extend or terminate the lease agreement. Facilities are primarily comprised of corporate offices, data centers, and R&D facilities. Equipment includes vehicles and various office equipment. The Company also has variable lease payments that are primarily comprised of common area maintenance and utility charges. The Company's lease agreements do not contain any residual value guarantees or restrictive covenants. The components of lease costs and other information related to leases were as follows (in millions, except years and percentages): Years Ended December 31, 2024 2023 Operating lease cost $ 50.9 $ 46.6 Variable lease cost 11.8 11.9 Total lease cost $ 62.7 $ 58.5 Operating cash outflows from operating leases $ 51.3 $ 51.6 ROU assets obtained in exchange for new operating lease liabilities $ 97.1 $ 12.4 As of December 31, 2024 2023 Weighted average remaining lease term (years) 6.4 3.6 Weighted average discount rate 4.7 % 3.8 % As of December 31, 2024, future operating lease payments for each of the next five years and thereafter are as follows (in millions): Years Ending December 31, Amount 2025 $ 46.1 2026 31.1 2027 28.8 2028 23.9 2029 20.9 Thereafter 63.0 Total lease payments 213.8 Less: interest (33.5) Total $ 180.3 Balance Sheet Information Other accrued liabilities $ 44.8 Long-term operating lease liabilities 135.5 Total $ 180.3 Debt and Interest Payment on Debt As of December 31, 2024, the Company held total outstanding debt consisting of the Notes with a carrying value of $1,615.1 million. See Note 8, Debt and Financing , for further discussion of the Company's long-term debt and expected future principal maturities. HPE Merger Contingencies In connection with the pending Merger, the Company expects to incur additional liabilities of approximately $155.2 million that are subject to the consummation of the Merger. These contingent liabilities include financial advisory fees, certain retention bonuses and legal fees, which will become payable upon consummation of the Merger. Tax Liability Our transition tax liability represents future cash payments on accumulated foreign earnings of subsidiaries as a result of the Tax Cuts and Jobs Act of 2017 ("Tax Act"). The Company has elected to pay its transition tax, net of applicable tax refunds, over the eight-year period provided in the Tax Act. The remaining balance of the Company's transition tax obligation of $102.0 million is to be paid within the next 12 months and is included within short-term income taxes payable as of December 31, 2024. Short-term income taxes payable are classified as other accrued liabilities in the Company's Consolidated Balance Sheets. As of December 31, 2024, the Company had $83.5 million included in long-term income taxes payable on the Consolidated Balance Sheets, primarily related to unrecognized tax positions. At this time, the Company is unable to make a reasonably reliable estimate of the timing of payments related to this amount due to uncertainties in the timing of tax audit outcomes. Guarantees The Company has financial guarantees consisting of third-party financing arrangements extended to end-user customers and standby letters of credit for certain lease facilities, insurance programs and customs of $27.8 million and $32.5 million, as of December 31, 2024 and December 31, 2023, respectively. Legal Proceedings In the ordinary course of business, the Company is subject to various pending and potential investigations, disputes, litigation, and legal proceedings. The Company records an accrual for loss contingencies for legal proceedings when it believes that an unfavorable outcome is both (a) probable and (b) the amount or range of any possible loss is reasonably estimable. The Company intends to aggressively defend itself in any legal matters, and while the outcome of any pending matters is not currently determinable, the Company believes that none of its currently existing claims or proceedings are likely, individually or in the aggregate, to have a material adverse effect on its financial position. Notwithstanding the foregoing, there are many uncertainties associated with any litigation and these matters or any other third-party claims against the Company may cause the Company to incur costly litigation and/or substantial settlement charges. In addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which could adversely affect gross margins in future periods. If any of these events were to occur, the Company's business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from the Company's estimates, if any, which could result in the need to adjust the liability and record additional expenses. DOJ Action . As previously disclosed, on January 9, 2024, we entered into the Merger Agreement with HPE and Merger Sub, providing for the acquisition of Juniper by HPE. On April 2, 2024, we received stockholder approval of the Merger Agreement at a special meeting of stockholders. On January 9, 2025, the Outside Date of the consummation of the Merger was extended pursuant to the terms of the Merger Agreement to April 9, 2025, which Outside Date may be automatically extended further to October 9, 2025, under certain circumstances. Completion of the Merger is subject to the satisfaction or waiver of certain closing conditions, including: (1) the expiration or early termination of the applicable waiting period under the HSR Act and certain other approvals, clearances or expirations of waiting periods under other antitrust laws and foreign investment laws, (2) the absence of any order, injunction, or other order or law prohibiting the Merger or making the closing of the Merger illegal, (3) the accuracy of each party’s representations and warranties, subject to certain standards set forth in the Merger Agreement, (4) the performance and compliance in all material respects of each party’s agreements and covenants under the Merger Agreement, and (5) in the case of the obligations of HPE and Merger Sub to effect the Merger, no Material Adverse Effect (as defined in the Merger Agreement) with respect to the Company, having occurred and that is continuing as of the closing. The Company has received all required regulatory approvals and clearances from all applicable countries except for the U.S. and Israel. On January 30, 2025, the DOJ filed a complaint seeking a preliminary and permanent injunction to prevent the completion of the Merger (the “DOJ Action”). The filing of the DOJ Action is delaying, and, if we and HPE are unsuccessful in defending against or settling the DOJ Action, could ultimately prevent, the consummation of the Merger. Both we and HPE have stated our disagreement with the DOJ's concerns set forth in the DOJ Action, and have stated the reasons why the claims in the DOJ Action are fundamentally flawed.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We recognize the importance of assessing, identifying, and managing material risks associated with cybersecurity threats, as such term is defined in Item 106(a) of Regulation S-K. These risks include, among other things, internal operational risks; system security risks; data protection; risks to proprietary business information; intellectual property theft; fraud; extortion; harm to employees, partners, or customers; violation of privacy or security laws and other litigation and legal risk; and reputational risks. We have implemented several cybersecurity processes, technologies, and controls to aid in our efforts to identify, assess, and manage such material risks. To aid in identifying and assessing material risks from cybersecurity threats, our enterprise risk management program considers cybersecurity risks alongside other significant company risks as part of our overall risk assessment process. As part of this process, the Company gathers input from subject matter specialists, as necessary, to gather insights to help in identifying and assessing material cybersecurity threat risks, as well as potential severity and mitigation measures. We also have a cybersecurity specific risk assessment process, which helps identify potential cybersecurity risks. We employ a range of tools and services, including regular network and endpoint monitoring, vulnerability assessments, penetration testing, and tabletop exercises to inform our professionals’ risk identification and assessment. We manage these known risks by using internal security controls incorporating principles from standards set by the National Institute of Standards and Technology (“NIST”), the International Organization for Standardization (“ISO”), and the Center for Internet Security (“CIS”), and by engaging third party experts to perform penetration tests to attempt to infiltrate our information systems, as such term is defined in Item 106(a) of Regulation S-K. These penetration tests are focused on specific objectives to assist us in managing our cybersecurity threat risks. Our maturity in these controls varies by control type and by business. We also conduct the following activities at various intervals during the year, which vary in maturity across our business: • monitor emerging data protection laws and implement changes from time-to-time to our processes designed to comply; • undertake regular reviews of our customer facing policies and statements related to cybersecurity; • through policy, practice, and contract (as applicable) require employees, who provide services on our behalf, to treat customer information and data with care; • leverage the NIST incident handling framework to help us prepare, detect, analyze, contain, eradicate, respond, and recover when there is an actual or potential cybersecurity incident; • run exercises to simulate a response to a cybersecurity incident and use the findings to improve our processes and technologies; • run exercises to simulate a response to a cybersecurity incident to provide training to our cyber incident response team; • run tabletop exercises to train our executives and increase their cybersecurity awareness; • conduct a variety of information security and privacy trainings, including new employee training, job-specific security training, specialized training for IT and security personnel, and phishing simulations. • hold an annual Cybersecurity Awareness Month programming, which is available for all employees during which we provide seminars, presentations, and employee engagement activities designed to reinforce our employee information security training and enhance the culture and knowledge of cybersecurity risks among our employees; • carry information security risk insurance to help defray potential losses that might arise from a cybersecurity incident. Our cybersecurity incident response plan was developed to respond to the threat of security breaches, the threat of cyberattacks, and to protect and preserve the confidentiality, integrity, and continued availability of information owned by, or in the care of, the Company. Our incident response plan coordinates the activities that we take to prepare for, detect, respond to, and recover from cybersecurity incidents, which include processes to triage, assess severity for, escalate material cybersecurity incidents to our global crisis management plan, contain, investigate, and remediate the incident, as well as to comply with potentially applicable legal obligations and mitigate brand and reputational damage. Our processes also address cybersecurity threat risks associated with our use of third-party service providers, including those in our supply chain or who have access to our customer and employee data or our systems. Third-party risks are included within our enterprise risk management assessment program, as well as our cybersecurity-specific risk identification program, both of which are discussed above. In addition, cybersecurity considerations affect the selection and oversight of our third-party service providers. We perform diligence on third parties that have access to our systems, data or facilities that house such systems or data, and continually monitor cybersecurity threat risks identified through such diligence. Additionally, we generally require those third parties that could introduce significant cybersecurity risk to us to agree by contract to manage their cybersecurity risks in specified ways, and to agree to be subject to cybersecurity audits. We regularly engage with assessors, consultants, auditors, and other third parties, including by regularly having third parties, including independent Qualified Security Assessors review our cybersecurity program to help identify areas for continued focus, improvement and/or compliance.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation
Use of Estimates	Use of Estimates The preparation of the financial statements and related disclosures in accordance with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in the Consolidated Financial Statements and the accompanying notes. The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes are reasonable under the circumstances, to determine the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from these estimates.
Cash, Cash Equivalents, and Investments	Cash, Cash Equivalents, and Investments Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, demand deposits with banks, highly liquid investments in money market funds, commercial paper, government securities, certificates of deposits, time deposits, and corporate debt securities, which are readily convertible into cash. All highly liquid investments with original maturities of three months or less from Juniper's purchase date are classified as cash equivalents.
Investments in Available-for-Sale Debt Securities and Equity Securities	Investments in Available-for-Sale Debt Securities The Company's investments in debt securities are classified as available-for-sale and include the Company's fixed income securities and investments in privately-held companies, consisting of debt and redeemable preferred stock securities. Fixed income securities primarily consist of corporate debt securities, U.S. treasury securities, time deposits, asset-backed and mortgage-backed securities, certificate of deposits, commercial paper, U.S. government agency securities, and foreign government debt securities. Fixed income securities are initially recorded at cost and periodically adjusted to fair value in the Consolidated Balance Sheets. The Company periodically evaluates these investments to determine if impairment charges are required. The Company determines whether a credit loss exists for available-for-sale debt securities in an unrealized loss position. When the fair value of a security is below its amortized cost, the amortized cost will be reduced to its fair value and the resulting loss will be recorded in Consolidated Statements of Operations, if it is more likely than not that we are required to sell the impaired security before recovery of its amortized cost basis, or we have the intention to sell the security. If neither of these conditions are met, the Company considers the extent to which the fair value is less than the amortized cost, any changes to the rating of the security by a rating agency, and review of the issuer's financial statements. If factors indicate a credit loss exists, an allowance for credit loss is recorded through other expense, net, limited by the amount that the fair value is less than the amortized cost basis. The Company's privately-held debt and redeemable preferred stock securities are included in other long-term assets in the Consolidated Balance Sheets and are recorded at fair value. In determining the estimated fair value of such securities, the Company utilizes the most recent data available for the investee including known acquisition offers and subsequent funding rounds. The Company periodically evaluates these securities for indicators of impairment, including the inability to recover a portion of or the entire carrying amount of the investment, the inability of the investee to sustain earnings, the reduction in or termination of financial commitment to the investee from other investors, the intention to sell the investment, and whether it is more likely than not that the Company will be required to sell the investment before recovery of the entire amortized cost basis. If the Company determines that the decline in an investment's value indicates credit losses, the difference is recognized as an impairment loss in its Consolidated Statements of Operations. For all available-for-sale debt securities, unrealized gains and the amount of unrealized loss relating to factors other than credit loss are reported as a separate component of accumulated other comprehensive loss in the Consolidated Balance Sheets. Realized gains and losses are determined based on the specific identification method and are reported in the Consolidated Statements of Operations. Investments in Equity Securities The Company's investments in equity securities with readily determinable fair values consist of money market funds, mutual funds, and an investment in a public company. These investments are measured at fair value with changes in fair value recognized in the Consolidated Statements of Operations. Equity securities without readily determinable fair values include the Company's investments in privately-held companies consisting of non-redeemable preferred stock and common stock securities. The Company accounts for these securities at cost, adjusted for changes from observable transactions for identical or similar investments of the same issuer, less impairments. Fair value of these equity securities is reassessed when the Company identifies observable price changes indicating that an adjustment upward or downward to the carrying value is necessary. Any observable changes in fair value are recognized in earnings as of the date that the observable transaction took place. In addition, the Company periodically evaluates equity securities without readily determinable fair values to determine if impairment charges are required by evaluating whether an event or change in circumstance has occurred that may have a significant adverse effect on the fair value of the investment. A qualitative assessment is performed each reporting period to assess whether there are any impairment indicators, including, but not limited to, significant deterioration in the investee's earnings performance; credit rating; asset quality or business prospects; adverse change in the regulatory, economic, or technological environment; change in the general market condition of the geographic area or industry; acquisition offers; and the ability to continue as a going concern. If such indicators are present, the Company estimates the fair value of impaired investments and recognizes an impairment loss in the Consolidated Statement of Operations equal to the difference between the carrying value and fair value.
Fair Value	Fair Value Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, the Company considers the principal or most advantageous market in which it transacts, and considers assumptions that market participants would use when pricing the asset or liability. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. These inputs are valued using market-based approaches. Level 3 – Inputs are unobservable inputs based on the Company’s assumptions. These inputs, if any, are valued using internal financial models.
Derivative Instruments	Derivative Instruments The Company uses derivative instruments, primarily foreign currency forward and interest rate contracts, to hedge certain foreign currency and interest rate exposures. The Company does not enter into derivatives for speculative or trading purposes. The Company uses foreign currency forward contracts or options contracts to hedge certain forecasted foreign currency transactions relating to operating expenses. These derivatives are designated as cash flow hedges, which are carried at fair value with the derivative's gain or loss initially reported as a component of accumulated other comprehensive loss, and upon occurrence of the forecasted transaction, is subsequently reclassified into the costs of services or operating expense line item to which the hedged transaction relates. Cash flows from such hedges are classified as operating activities. The Company also uses foreign currency forward contracts to mitigate variability in gains and losses generated from the re-measurement of certain monetary assets and liabilities denominated in non-functional currencies. These derivatives are carried at fair value with changes recorded in other expense, net in the Consolidated Statements of Operations in the same period as the changes in the fair value from the re-measurement of the underlying assets and liabilities. Cash flows from such derivatives are classified as operating activities. The Company uses interest rate swap contracts to convert certain of our fixed interest rate notes to floating interest rates based on the Secured Overnight Financing Rate (SOFR). All interest rate swap contracts will expire within seven years. The change in fair value of the derivative instrument substantially offsets the change in the fair value of the hedged item. These derivatives are classified in the Consolidated Statements of Cash Flows in the same section as the underlying item. The Company uses interest rate lock contracts, which fix the benchmark interest rates of future debt issuance. The Company records changes in fair value of these contracts in accumulated other comprehensive income (loss) in the Consolidated Balance Sheets, in the period of change. When the forecasted transaction occurs, the Company will start to amortize the accumulated gains or losses included as a component of other comprehensive income (loss) related to the interest rate lock cash flow hedges to interest expense. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, the gains or losses on the related cash flow hedge from accumulated other comprehensive income (loss) will be reclassified to other income and expense within the income statement. During the year ended December 31, 2024 , the Company terminated these interest rate lock contracts. Refer to Note 4, Derivative Instruments . The Company presents its derivative assets and derivative liabilities on a gross basis in the Consolidated Balance Sheets. However, under agreements containing provisions on set-off with certain counterparties, subject to applicable requirements, the Company is allowed to net-settle transactions, with a single net amount payable by one party to the other. The Company is neither required to pledge nor entitled to receive cash collateral related to these derivative transactions.
Inventory	Inventory Inventory consists primarily of component parts to be used in the manufacturing process and finished goods, and is stated at the lower of cost or net realizable value. In addition, the Company purchases and holds inventory to provide adequate component supplies over the life of the underlying products. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. A charge is recorded to cost of product when inventory is determined to be in excess of anticipated demand or considered obsolete. At the point of loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in the newly established cost basis.
Leases	Leases The Company determines if an arrangement is a lease at inception. The Company evaluates classification of leases as either operating or finance at commencement and, as necessary, at modification. As of December 31, 2024, the Company did not have any finance leases. Operating leases are included in operating lease right-of-use ("ROU") assets, other accrued liabilities, and operating lease liabilities on the Company's Consolidated Balance Sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized on the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made prior to lease commencement and excludes lease incentives. Variable lease payments not dependent on an index or a rate, are expensed as incurred and are not included within the ROU asset and lease liability calculation. Variable lease payments primarily include reimbursements of costs incurred by lessors for common area maintenance and utilities. The Company's lease terms are the noncancelable period, including any rent-free periods provided by the lessor, and include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. At lease inception, and in subsequent periods as necessary, the Company estimates the lease term based on its assessment of extension and termination options that are reasonably certain to be exercised. Lease costs are recognized on a straight-line basis over the lease term. The Company does not separate non-lease components from lease components for all underlying classes of assets. In addition, the Company does not recognize ROU assets and lease liabilities for short-term leases, which have a lease term of twelve months or less and do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. Lease cost for short-term leases is recognized on a straight-line basis over the lease term.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost less accumulated depreciation. Depreciation is calculated using the straight-line method, over the estimated useful lives of the following assets: Estimated Useful Life (years) Computers, equipment, and software 1.5 to 10 Furniture and fixtures 5 to 7 Building and building improvements 7 to 40 Land improvements 10 to 40 Leasehold improvements Lease term, not to exceed 10 years
Business Combinations	Business Combinations The purchase price of an acquired entity is allocated to tangible assets, liabilities, and intangible assets based on their estimated fair values with the residual of the purchase price recorded as goodwill. The determination of the value of the intangible assets acquired involves certain estimates, such as expected future cash flows, which include consideration of future growth rates and margins, attrition rates, future changes in technology, discount rates, and the expected use of the acquired assets. These factors are also considered in determining the useful life of the acquired intangible assets. Acquisition related expenses are recognized separately from the business combination and are expensed as incurred. The Company's Consolidated Financial Statements include the operating results of acquired businesses from the date of each acquisition.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is tested for impairment annually on November 1 or more frequently if certain circumstances indicate the carrying value of goodwill is impaired. Goodwill is tested for impairment at the reporting unit level. A qualitative assessment is first performed to determine whether it is necessary to quantitatively test goodwill for impairment. This initial assessment includes, among others, consideration of macroeconomic conditions and financial performance. If the qualitative assessment indicates that it is more likely than not that an impairment exists, a quantitative analysis is performed by determining the fair value of the reporting unit using a combination of the discounted cash flow and the market approaches. Goodwill is considered impaired if the carrying value of the reporting unit exceeds its fair value. A goodwill impairment loss is recognized for the amount that the carrying amount of the reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit.
Impairment of Long-lived Assets	Impairment of Long-lived Assets Long-lived assets, such as property, plant, and equipment, ROU assets, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group, to estimated undiscounted future cash flows expected to be generated by the asset, or asset group. An impairment charge is recognized by the amount by which the carrying amount of the asset, or asset group, exceeds its fair value.
Warranty Reserves	Warranty Reserves The Company generally offers a one-year warranty or limited life-time warranty on most of its hardware products, and a 90-day warranty on the media that contains the software embedded in the products. Warranty costs are recognized as part of the Company's cost of sales based on associated material costs, logistics costs, labor costs, and overhead at the time revenue is recognized. Material costs are estimated primarily based upon the historical costs to repair or replace product returns within the warranty period. Labor, logistics, and overhead costs are estimated primarily based upon historical trends in the cost to support customer cases within the warranty period. Warranty reserve is reported within other accrued liabilities in the Consolidated Balance Sheets.
Contract Manufacturer Liabilities	Contract Manufacturer Liabilities
Loss Contingencies	Loss Contingencies
Foreign Currency	Foreign Currency Assets and liabilities of foreign operations with non-U.S. Dollar functional currency are translated to U.S. Dollars using exchange rates in effect at the end of the period. Revenue and expenses are translated to U.S. Dollars using rates that approximate those in effect during the period. The resulting translation adjustments are included in the Company’s Consolidated Balance Sheets in the stockholders’ equity section as a component of accumulated other comprehensive loss. The Company remeasures monetary assets and monetary liabilities in non-functional currencies and records the resulting foreign exchange transaction gains and losses in other expense, net in the Consolidated Statements of Operations.
Revenue Recognition and Deferred Contract Costs	Revenue Recognition Revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services by following a five-step process, (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price, and (5) recognize revenue when or as the Company satisfies a performance obligation, as further described below. Identify the contract with a customer . The Company generally considers a sales contract and/or agreement with an approved purchase order as a customer contract provided that collection is considered probable, which is assessed based on the creditworthiness of the customer as determined by credit checks, payment histories, and/or other circumstances. The Company combines contracts with a customer if contracts are negotiated with a single commercial substance or contain price dependencies. Identify the performance obligations in the contract . Product performance obligations include hardware, software licenses including perpetual and term-based licenses, and service performance obligations including maintenance services, Software-as-a-Service ("SaaS"), education and training, and professional services. Determine the transaction price . The transaction price for the Company’s contracts with its customers consists of both fixed and variable consideration, provided it is probable that a significant reversal of revenue will not occur when the uncertainty related to variable consideration is resolved. Fixed consideration includes amounts to be contractually billed to the customer while variable consideration includes estimates for rights of return, rebates, and price protection, which are based on historical sales returns and price protection credits, specific criteria outlined in rebate agreements, and other factors known at the time. The Company generally invoices customers for hardware, software licenses and related maintenance arrangements at time of delivery, and professional services either upfront or upon meeting certain milestones. Customer invoices are generally due within 30 to 90 days after issuance. The Company’s contracts with customers typically do not include significant financing components as the period between the transfer of performance obligations and timing of payment are generally within one year. Allocate the transaction price to the performance obligations in the contract . For contracts that contain multiple performance obligations, the Company allocates the transaction price to the performance obligations on a relative stand-alone selling price ("SSP") basis. SSP is based on multiple factors including, but not limited to historical discounting trends for products and services, pricing practices in different geographies and through different sales channels, gross margin objectives, internal costs, competitor pricing strategies, and industry technology lifecycles. Recognize revenue when or as the Company satisfies a performance obligation . Revenue for hardware and certain software licenses, are recognized at a point in time, which is generally upon shipment or delivery. Certain software licenses are recognized on a ratable basis over the term of the license. Revenue for maintenance services and SaaS is recognized on a ratable basis over the contract term. Revenue from education, training, and professional services is recognized as services are completed or ratably over the contractual period of generally one year or less. Deferred product revenue represents unrecognized revenue related to undelivered product commitments and other shipments that have not met revenue recognition criteria. Deferred service revenue represents billed amounts for service contracts, which include technical support, hardware and software maintenance, professional services, SaaS, and education and training, for which services have not been rendered. Revenue is recognized net of any taxes collected, which are subsequently remitted to governmental authorities. Deferred Contract Costs Sales commissions earned by the Company’s sales force are considered incremental and recoverable costs of obtaining a contract with a customer. The Company capitalizes these costs, for which the transfer of the goods or services to which the asset relates will occur in future periods. These costs are recorded as prepaid expenses or other long-term assets and are deferred and then amortized over a period of benefit which is typically over the term of the customer contracts. Amortization expense is included in sales and marketing expenses in the accompanying Consolidated Statements of Operations.
Research and Development	Research and Development
Software Development Costs	Software Development Costs Capitalization of software development costs for software to be sold, leased, or otherwise marketed begins when a product's technological feasibility has been established and ends when a product is available for general release to customers. Generally, the Company's products are released soon after technological feasibility has been established. As a result, costs incurred between achieving technological feasibility and product general availability have not been significant. The Company capitalizes costs associated with internal-use software systems during the application development stage. Such capitalized costs include external direct costs incurred in developing or obtaining the applications and payroll and payroll-related costs for employees, who are directly associated with the development of the applications.

Share-Based Compensation	Share-Based Compensation The Company measures and recognizes compensation cost for all share-based awards made to employees and directors, including employee stock options, restricted stock awards ("RSAs"), restricted stock units ("RSUs"), performance share awards ("PSAs") and employee stock purchases related to the Employee Stock Purchase Plan ("ESPP"). For service condition only awards, share-based compensation expense is based on the fair value of the underlying awards and amortized on a straight-line basis. For PSAs, share-based compensation expense is amortized on a straight-line basis for each separate vesting portion of the awards. The Company accounts for forfeitures as they occur. The Company utilizes the Black-Scholes-Merton (“BSM”) option-pricing model to estimate the fair value of its ESPP purchase rights. The BSM model requires various highly subjective assumptions that represent management's best estimates of volatility, risk-free interest rate, expected life, and dividend yield. The Company estimates expected volatility based on the implied volatility of market-traded options, on the Company's common stock, adjusted for other relevant factors including historical volatility of the Company’s common stock over the most recent period commensurate with the estimated expected life of the Company’s ESPP. The expected life of ESPP purchase rights approximates the offering period. The Company determines the grant date fair value of its RSUs, RSAs, and PSAs based on the closing market price of the Company’s common stock on the date of grant, adjusted by the present value of the dividends expected to be paid on the underlying shares of common stock during the requisite and derived service period as these awards are not entitled to receive dividends until vested.
Provision for Income Taxes	Provision for Income Taxes Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized. The Company accounts for uncertainty in income taxes using a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that the Company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes. The Company accounts for the current impacts of U.S. tax on certain foreign subsidiaries income, which is referred to as Global Intangible Low-Taxed Income, in the year earned.
Concentrations of Risk	Concentrations of Risk Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments, derivatives, and accounts receivable. The Company invests only in high-quality credit instruments and maintains its cash, cash equivalents, and available-for-sale investments in fixed income securities with several high-quality institutions. Deposits held with banks, including those held in foreign branches of global banks, may exceed the amount of insurance provided on such deposits. We mitigate the concentration of credit risk in our investment portfolio through diversification of the investments in various industries and asset classes, and limits to the amount of credit exposure to any single issuer and credit rating. The Company’s derivatives expose it to credit risk to the extent that counterparties may be unable to meet the terms of the agreement. The Company has a risk assessment and mitigation framework to evaluate the potential risk of loss with any one counterparty resulting from this type of credit risk. As part of this risk mitigation framework, the Company transacts with major financial institutions with high credit ratings and also enters into master netting agreements, which permit net settlement of the transactions with the same counterparty. The Company performs periodic evaluations of the relative credit standing of these financial institutions. Therefore, the Company does not expect material losses as a result of defaults by counterparties. Generally, credit risk with respect to accounts receivable is diversified due to the number of entities comprising the Company's customer base and their dispersion across different geographic locations throughout the world. The Company performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable. For the years ended December 31, 2024, 2023, and 2022, no single customer accounted for 10% or more of net revenues.
Recently Adopted Accounting Standards and Recent Accounting Standards Not Yet Adopted	Recently Adopted Accounting Standards Improvements to Reportable Segment Disclosures: Effective January 1, 2024, the Company adopted ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07), which requires disclosure of incremental segment information on an annual and interim basis. The adoption of ASU 2023-07 did not have a material impact on the Company's Consolidated Financial Statements. Recent Accounting Standards Not Yet Adopted Improvements to Income Tax Disclosures: In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which expands the disclosures required for income taxes. This ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendment should be applied on a prospective basis while retrospective application is permitted. The Company is currently evaluating the effect of this pronouncement on its disclosures. Disaggregation of Income Statement Expenses: In November 2024, the Financial Accounting Standards Board (FASB) issued ASU 2024-03, Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional disclosures of specific expense categories included within each expense caption presented on the Consolidated Statements of Operations. This ASU is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027. The amendment should be applied on a prospective basis while retrospective application is permitted. The Company is currently evaluating the impact of this pronouncement on its financial statement disclosures.
Net Income per Share	Basic net income per share is computed using net income available to common stockholders and the weighted-average number of common shares outstanding for the period. Diluted net income per share is computed using net income available to common stockholders and the weighted-average number of common shares outstanding plus potentially dilutive common shares outstanding during the period. Dilutive potential common shares consist of common shares issuable upon exercise of stock options and purchase rights, and vesting of RSUs, RSAs, and PSAs. The Company includes the common shares underlying PSAs in the calculation of diluted net income per share only when they become contingently issuable. Anti-dilutive shares are excluded from the computation of diluted net income per share.
