NetScout Systems, Inc.
Notes to Consolidated Financial Statements
(Unaudited)
NOTE 1 – BASIS OF PRESENTATION
The accompanying unaudited interim consolidated financial statements have been prepared by NetScout Systems, Inc. (NetScout or the Company). Certain information and footnote disclosures normally included in financial statements prepared under United States generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, the unaudited interim consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the Company's financial position and stockholders' equity, results of operations and cash flows. The year-end consolidated balance sheet data and statement of stockholders' equity were derived from the Company's audited financial statements, but do not include all disclosures required by GAAP. The results reported in these unaudited interim consolidated financial statements are not necessarily indicative of results that may be expected for the entire year. All significant intercompany accounts and transactions are eliminated in consolidation.
These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company's Annual Report on Form 10-K for the fiscal year ended March 31, 2024 filed with the Securities and Exchange Commission on May 16, 2024.
Global and Macroeconomic Conditions
The Company continues to closely monitor the current global and macroeconomic conditions, including the impacts of the ongoing war in Ukraine and hostilities in the Middle East, global geopolitical tension, stock market volatility, industry-specific capital spending trends, exchange rate fluctuations, inflation, interest rates, and the risk of a recession, including the manner and extent to which they have impacted and could continue to impact its business, customers, employees, supply chain, and distribution network. The full extent of the impacts of these global and macroeconomic trends remain uncertain. It is possible that the measures taken by the governments of countries affected and the resulting economic impacts may materially and adversely affect the Company's future results of operations, cash flows and financial position as well as its customers.
The Company has the responsibility to evaluate whether conditions and/or events raise substantial doubt about its ability to meet its future financial obligations as they become due within one year after the date that the financial statements are issued. The macroeconomic environment remains challenging with constrained customer spending and the Company expects this to persist for the remainder of fiscal year 2025. The Company has taken and continues to take precautionary actions to manage costs and increase productivity across the organization. This includes managing discretionary spending and hiring activities, in addition to a voluntary separation program enacted and substantially completed in the first half of fiscal year 2025. Further, based on covenant levels, the Company had as of September 30, 2024 an incremental $725 million available under the revolving credit facility. On October 4, 2024, the Company amended and extended its Amended Credit facility, which decreased the revolving credit facility from $800 million to $600 million and reduced the incremental amount available under its revolving credit facility to $525 million. See Note 20 "Subsequent Events" for more details.
The Company expects net cash provided by operations combined with cash, cash equivalents, marketable securities and investments and borrowing availability under the revolving credit facility to provide sufficient liquidity to fund current obligations, capital spending, debt service requirements and working capital requirements over at least the next twelve months.
Recent Accounting Pronouncements
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments address investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. The amendments are effective retrospectively for fiscal years beginning after December 15, 2024. The amendments should be applied prospectively; however, retrospective application is also permitted. ASU 2023-09 is effective for NetScout beginning April 1, 2025. Early adoption is permitted. The Company is in the process of evaluating the impact that the adoption ASU 2023-09 will have to the financial statements and related disclosures.
In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which provides updates to qualitative and quantitative reportable segment disclosure requirements, including enhanced disclosures about significant segment expenses and increased interim disclosure requirements, among others. The amendments in ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments should be applied retrospectively. The Company plans to adopt ASU 2023-07 beginning with its fiscal year ending March 31, 2025. The

NOTE 2 – REVENUE
Revenue Recognition Policy
The Company exercises judgment and uses estimates in connection with determining the amounts of product and service revenues to be recognized in each accounting period.
The Company derives revenues primarily from the sale of network management tools and cybersecurity solutions for service provider and enterprise customers, which include hardware, software, and service offerings. The Company's product sales consist of software only offerings and offerings which include hardware appliances with embedded software that are essential to providing customers the intended functionality of the solutions.
The Company accounts for revenue once a legally enforceable contract with a customer has been approved by the parties and the related promises to transfer products or services have been identified. A contract is defined by the Company as an arrangement with commercial substance identifying payment terms, each party's rights and obligations regarding the products or services to be transferred and the amount the Company deems probable of collection. Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. Revenue is recognized when control of the products or services are transferred to the Company's customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for products and services.
Product revenue is typically recognized upon fulfillment, provided a legally enforceable contract exists, control has passed to the customer, and in the case of software products, when the customer has the rights and ability to access the software, and collection of the related receivable is probable. If any significant obligations to the customer remain post-delivery, typically involving obligations relating to installation and acceptance by the customer, revenue recognition is deferred until such obligations have been fulfilled. The Company's service offerings include installation, integration, extended warranty and maintenance services, post-contract customer support, stand-ready software-as-a-service (SAAS) and other professional services including consulting and training. The Company generally provides software and/or hardware support as part of product sales. Revenue related to the initial bundled software and hardware support is recognized ratably over the support period. In addition, customers can elect to purchase extended support agreements for periods after the initial software/hardware warranty expiration. Support services generally include rights to unspecified upgrades (when and if available), telephone and internet-based support, updates, bug fixes and hardware repair and replacement. Consulting services are recognized upon delivery or completion of performance depending on the terms of the underlying contract. Reimbursements of out-of-pocket expenditures incurred in connection with providing consulting services are included in services revenue, with the offsetting expense recorded in cost of service revenue. Training services include on-site and classroom training. Training revenues are recognized upon delivery of the training.
Generally, the Company's contracts are accounted for individually. However, when contracts are closely interrelated and dependent on each other, it may be necessary to account for two or more contracts as one to reflect the substance of the group of contracts.
Bundled arrangements are concurrent customer purchases of a combination of the Company's product and service offerings that may be delivered at various points in time. The Company allocates the transaction price among the performance obligations in an amount that depicts the relative standalone selling prices (SSP) of each obligation. Judgment is required to determine the SSP for each distinct performance obligation. The Company uses a range of amounts to estimate SSP for each of the products and services sold, based primarily on the performance obligation's historical pricing. The Company also considers its overall pricing objectives and practices across different sales channels and geographies, and market conditions. Generally, the Company has established SSP for a majority of its service performance obligations based on historical standalone sales. In certain instances, the Company has established SSP for services based upon an estimate of profitability and the underlying cost to fulfill those services. SSP has primarily been established for product performance obligations as the average or median selling price the performance obligation was recently sold for, whether sold alone or sold as part of a bundle transaction. The Company reviews sales of the product performance obligations on a quarterly basis and updates, when appropriate, its SSP for such performance obligations to ensure that it reflects recent pricing experience. The Company's products are distributed through its direct sales force and indirect distribution channels through alliances with resellers and distributors. Revenue arrangements with resellers and distributors are recognized on a sell-in basis; that is, when control of the product transfers to the reseller or distributor. The Company records consideration given to a customer as a reduction of revenue to the extent they have recorded revenue from the customer. With limited exceptions, the Company's return policy does not allow product returns for a
9

refund. Returns have been insignificant to date. In addition, the Company has a history of successfully collecting receivables from its resellers and distributors.
During the six months ended September 30, 2024, the Company recognized revenue of $183.5 million related to the Company's deferred revenue balance reported at March 31, 2024.
Performance Obligations
Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. The transaction price is allocated among performance obligations in bundled contracts in an amount that depicts the relative standalone selling prices of each obligation.
For contracts involving distinct hardware and software licenses, the performance obligations are satisfied at a point in time when control is transferred to the customer. For standalone maintenance and post-contract support (PCS) the performance obligation is satisfied ratably over the contract term as a stand-ready obligation. For consulting and training services, the performance obligation may be satisfied over the contract term as a stand-ready obligation, satisfied over a period of time as those services are delivered, satisfied at the completion of the service when control has transferred, or the services have expired unused.
Payments for hardware, software licenses, one-year maintenance, PCS and consulting services, are typically due up front with payment terms of 30 to 90 days. However, the Company does have contracts pursuant to which billings occur ratably over a period of years following the transfer of control for the contracted performance obligations. Payments on multi-year maintenance, PCS and consulting services are typically due in annual installments over the contract term. The Company did not have any material variable consideration such as obligations for returns, refunds or warranties at September 30, 2024.
At September 30, 2024, the Company had total deferred revenue of $379.7 million, which represents the aggregate total contract price allocated to undelivered performance obligations. The Company expects to recognize $263.9 million, or 69%, of this revenue during the next 12 months, and expects to recognize the remaining $115.8 million, or 31%, of this revenue thereafter.
Because of NetScout's revenue recognition policies, there are circumstances for which the Company does not recognize revenue relating to sales transactions that have been billed, but the related account receivable has not been collected. While the receivable represents an enforceable obligation, the Company does not believe its right to payment is unconditional, therefore for balance sheet presentation purposes, the Company has not recognized the deferred revenue or the related account receivable and no amounts appear in the consolidated balance sheets for such transactions because control of the underlying deliverable has not transferred. The aggregate amount of unrecognized accounts receivable and deferred revenue was $7.6 million and $5.9 million at September 30, 2024 and March 31, 2024, respectively.
NetScout expects that the amount of billed and unbilled deferred revenue will change from quarter to quarter for several reasons, including the specific timing, duration and size of large customer support and service agreements, varying billing cycles of such agreements, the specific timing of customer renewals, and foreign currency fluctuations. The Company did not have material significant financing components, or variable consideration or performance obligations satisfied in a prior period recognized during the six months ended September 30, 2024.
Contract Balances
The Company may receive payments from customers based on billing schedules as established by the Company's contracts. Contract assets relate to performance obligations where control has transferred to the customer in advance of scheduled billings. The Company records unbilled accounts receivable representing the right to consideration in exchange for goods or services that have been transferred to a customer conditional on the passage of time. Deferred revenue relates to scenarios where billings with an unconditional right to payment occur before all performance obligations are delivered or payments are received in advance of performance under the contract.
Costs to Obtain Contracts
The Company has determined that the only significant incremental costs incurred to obtain contracts with customers within the scope of Topic 606 are sales commissions paid to its employees. Sales commissions are recorded as an asset and amortized to expense ratably over the remaining performance periods of the related contracts with remaining performance obligations. The Company expenses costs as incurred for sales commissions when the amortization period would have been one year or less.
At September 30, 2024, the consolidated balance sheet included $9.0 million in assets related to sales commissions to be expensed in future periods. A balance of $4.8 million was included in prepaid expenses and other current assets, and a balance
10

of $4.2 million was included in other assets in the Company's consolidated balance sheet at September 30, 2024. At March 31, 2024, the consolidated balance sheet included $9.3 million in assets related to sales commissions to be expensed in future periods. A balance of $4.8 million was included in prepaid expenses and other current assets, and a balance of $4.5 million was included in other assets in the Company's consolidated balance sheet at March 31, 2024.
During the three and six months ended September 30, 2024 and 2023, respectively, the Company recognized $1.7 million, $1.7 million, $3.4 million and $3.4 million of amortization related to this sales commission asset, which is included in the sales and marketing expense line in the Company's consolidated statements of operations.
Allowance for Credit Losses
The Company continually monitors collections from its customers. The Company evaluates the collectability of its accounts receivable and determines the appropriate allowance for credit losses based on a combination of factors, including but not limited to, analysis of the aging schedules, past due balances, historical collection experience and prevailing economic conditions.
The following table summarizes the activity in the allowance for credit losses (in thousands):

NOTE 3 – CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS
Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of investments, trade accounts receivable and accounts payable. The Company's cash, cash equivalents, and marketable securities are placed with financial institutions with high credit standings.
At September 30, 2024, the Company had one direct customer over 10% of the accounts receivable balance, while no channel partners accounted for more than 10% of the accounts receivable balance. At March 31, 2024, the Company had no direct customers or channel partners which accounted for more than 10% of the accounts receivable balance.
During the three and six months ended September 30, 2024, and 2023, no direct customers or channel partners accounted for more than 10% of total revenue.
Historically, the Company has not experienced any significant failure of its customers' ability to meet their payment obligations nor does the Company anticipate material non-performance by its customers in the future; accordingly, the Company does not require collateral from its customers. However, if the Company's assumptions are incorrect, there could be an adverse impact on its allowance for doubtful accounts.
NOTE 4 – SHARE-BASED COMPENSATION
On September 12, 2019, the Company's stockholders approved the 2019 Equity Incentive Plan (2019 Plan), which replaced the Company's 2007 Equity Incentive Plan, as amended (Amended 2007 Plan). The 2019 Plan permits the granting of incentive and nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and other stock awards, collectively referred to as "share-based awards."
On September 10, 2020, the Company's stockholders approved an amendment and restatement of the 2019 Equity Incentive Plan (2019 First Amended Plan) to increase the number of shares reserved for issuance by 4,700,000 shares, establish a one-year minimum vesting requirement for awards granted on or after September 10, 2020, and change the "fungible share counting ratio" used to calculate the increase or reduction in the number of shares available for issuance under the 2019 First Amended Plan.
On August 24, 2022, the Company's stockholders approved an amendment and restatement of the 2019 Equity Incentive Plan (2019 Second Amended Plan) to increase the number of shares reserved for issuance by 7,000,000 shares, and change the "fungible share counting ratio" used to calculate the increase or reduction in the number of shares available for issuance under the 2019 Second Amended Plan.
On September 14, 2023, the Company's stockholders approved an amendment and restatement to the 2019 First Amended Plan (2019 Third Amended Plan) to further increase the number of shares reserved for issuance by 5,900,000 shares and
11

changed the "fungible share counting ratio" used to calculate the increase or reduction in the number of shares available for issuance under the 2019 Third Amended Plan.
On September 12, 2024, the Company’s stockholders approved an amendment and restatement to the 2019 First Amended Plan (2019 Fourth Amended Plan) to further increase the number of shares reserved for issuance by 3,400,000. At September 12, 2024, the effective date of the 2019 Fourth Amended Plan, there was a total of 7,947,545 shares reserved for issuance under the 2019 Fourth Amended Plan, which consisted of 3,400,000 new shares plus 4,547,545 shares that remained available for grant under the 2019 Third Amended Plan. The Company refers to the 2019 Plan, 2019 First Amended Plan, 2019 Second Amended Plan, 2019 Third Amended Plan and 2019 Fourth Amended Plan collectively as the "Amended 2019 Plan". At September 30, 2024, an aggregate of 8,020,927 shares remained available for grant under the Amended 2019 Plan.
Periodically, the Company grants share-based awards to employees, officers, and directors of the Company and its subsidiaries. Additionally, the Company periodically grants performance-based restricted stock units to certain executive officers that vest based upon the Company's total shareholder return as compared to the Russell 2000 Index over a three-year period. The performance-based restricted stock units are valued using the Monte Carlo Simulation model. The measurement and recognition of compensation expense is based on estimated fair values for all share-based payment awards made to its employees and directors. Share-based award grants are generally measured at fair value on the date of grant based on the number of shares granted and the quoted price of the Company's common stock. Such value is recognized as a cost of revenue or an operating expense over the corresponding vesting period.
The following is a summary of share-based compensation expense including restricted stock units and performance-based restricted stock units granted pursuant to the Company's Amended 2007 Plan and the Amended 2019 Plan, and employee stock purchases made under the Company's 2011 Amended and Restated Employee Stock Purchase Plan (ESPP), based on estimated fair values within the applicable cost and expense lines identified below (in thousands):

Investments
In February 2023, the Company entered into a forward share purchase agreement with Napatech A/S (Napatech), a publicly traded Danish company registered on the Oslo stock exchange, to purchase approximately 6.2 million shares of Napatech's common stock for $7.5 million. In April 2023, the Company settled the forward share purchase contract with Napatech in exchange for approximately 6.2 million shares of Napatech's common stock and recorded a $0.2 million change in the fair value of the derivative instrument in other income (expense), net within the Company's consolidated statement of operations during the six months ended September 30, 2023. As part of the agreement, the Company received the right to designate a representative to be nominated for election to the Napatech Board of Directors, which was approved by Napatech's Nomination Committee in April 2023. The Company accounts for this investment under the equity method and has elected to apply the fair value option to the investment. The Company records the investment at fair value at the end of each period based on the closing price of Napatech's stock and any change in fair value during the period is recorded in other income (expense), net within the Company's consolidated statement of operations. At September 30, 2024 and March 31, 2024, the fair value of the investment in Napatech was $19.8 million and $11.5 million, respectively, and was included in marketable securities and investments in the Company's consolidated balance sheet. During the six months ended September 30, 2024 and 2023, the Company recognized a $7.6 million increase and a $0.1 million increase, respectively, in the fair value of the equity investment
13

in Napatech in other income (expense), net within the Company's consolidated statement of operations. For the six months ended September 30, 2024, the unrealized gain related to foreign currency translation on the equity investment in Napatech was $0.7 million. For the six months ended September 30, 2023, the unrealized loss related to foreign currency translation on the equity investment in Napatech was immaterial.
NOTE 6 – FAIR VALUE MEASUREMENTS
The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant non-observable inputs. The following tables present the Company's financial assets and liabilities measured on a recurring basis using the fair value hierarchy at September 30, 2024 and March 31, 2024 (in thousands):

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures certain financial assets and liabilities at fair value, including marketable securities and derivative financial instruments.
The Company's Level 1 investments are classified as such because they are valued using quoted market prices or alternative pricing sources with reasonable levels of price transparency.
The Company's Level 2 investments are classified as such because they are valued using observable inputs other than Level 1 quoted prices that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets in markets that are not active.

NOTE 8 - DIVESTITURES
Business Divestiture
On September 8, 2023, the Company entered into an Asset Purchase Agreement to divest its Test Optimization business (TO Business) for a purchase price of $7.8 million, inclusive of a working capital adjustment. The Company recorded a gain of $3.8 million on the divestiture during the three and six months ended September 30, 2023.
The Company determined that the sale of the TO Business did not represent a strategic shift and will not have a major effect on its consolidated results of operations, financial position or cash flow. Accordingly, the Company has not presented the sale as a discontinued operation in the consolidated financial statements.
NOTE 9 – GOODWILL AND INTANGIBLE ASSETS
Goodwill
The Company has one reporting unit. Goodwill is tested for impairment at a reporting unit level at least annually, as of January 31, or on an interim basis if an event occurs or circumstances change (a "Triggering Event") that would, more likely than not, reduce the fair value of the reporting unit below its carrying value.
During fiscal year 2024, the Company recorded $217.3 million in goodwill impairment charges as a result of the sustained decline in the Company's stock price and overall market capitalization. During the first quarter of fiscal year 2025, due to the continued decrease in the Company's stock price and overall market capitalization, along with other qualitative considerations including the continued impact from the conditions in the macroeconomic environment, it was determined a Triggering Event occurred, indicating goodwill may be impaired. Accordingly, the Company conducted a quantitative impairment test of its goodwill at June 30, 2024. The Company estimated the implied fair value of its goodwill using a market approach. As a result of the quantitative impairment test performed during the first quarter of fiscal year 2025, the Company determined goodwill was impaired and recorded a goodwill impairment charge of $427.0 million during the three months ended June 30, 2024. The additional impairment charge recorded in the first quarter of fiscal year 2025 was primarily due to the continued decrease in the Company's stock price from March 31, 2024 to June 30, 2024, an increase in the Company's weighted-average cost of capital, and the refinement to the expected cost synergies that could be realized by a hypothetical buyer as a result of the voluntary separation program (VSP) implemented by the Company in the first quarter of fiscal year 2025, which impacted the company-specific control premium used to determine the fair value of the reporting unit under the market approach. At September 30, 2024, the Company performed a Triggering Event assessment and concluded no event or circumstances occurred that indicated goodwill was further impaired.
Throughout the remainder of the fiscal year 2025, the Company will continue to monitor relevant facts and circumstances, including future changes in its stock price. The Company may be required to record additional goodwill impairment charges. While management cannot predict if or when additional goodwill impairments may occur, future goodwill impairments could have material adverse effects on the Company's results of operations and financial condition.
At September 30, 2024 and March 31, 2024, the carrying amounts of goodwill were $1.1 billion and $1.5 billion, respectively. The change in the carrying amount of goodwill for the six months ended September 30, 2024 was due to the impairment of goodwill, and the impact of foreign currency translation adjustments related to asset balances that are recorded in currencies other than the U.S. Dollar.

The following table summarizes the changes in the carrying amount of goodwill for the six months ended September 30, 2024 as follows (in thousands):

Intangible Assets
The net carrying amounts of intangible assets were $285.6 million and $308.7 million at September 30, 2024 and March 31, 2024, respectively. Intangible assets acquired in a business combination are recorded under the acquisition method of accounting at their estimated fair values at the date of acquisition. The Company amortizes acquired intangible assets over their estimated useful lives.
The Company reviews definite-lived intangible assets for impairment when an event occurs that may indicate potential impairment. In connection with the goodwill impairment analysis performed at June 30, 2024, the Company conducted an impairment test of its definite-lived intangible assets at June 30, 2024. Based on this assessment, the Company concluded that the carrying values of the Company's definite-lived intangible assets were recoverable. At September 30, 2024, the Company performed a Triggering Event assessment and concluded no events or circumstances occurred that indicated intangible assets may be impaired. However, if future events occur or if business conditions deteriorate, the Company may be required to record an impairment loss, and or accelerate the amortization of definite-live intangible assets in the future, which could be material to its results of operations and financial condition.

NOTE 10 – DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
NetScout operates internationally and, in the normal course of business, is exposed to fluctuations in foreign currency exchange rates. The exposures result from costs that are denominated in currencies other than the U.S. Dollar, primarily the Euro, British Pound, Canadian Dollar, and Indian Rupee. The Company manages its foreign cash flow risk by hedging forecasted cash flows for operating expenses denominated in foreign currencies for up to twelve months, within specified guidelines through the use of forward contracts. The Company enters into foreign currency exchange contracts to hedge cash flow exposures from costs that are denominated in currencies other than the U.S. Dollar. These hedges are designated as cash flow hedges at inception.
NetScout also periodically enters into forward contracts to manage exchange rate risks associated with certain third-party transactions and for which the Company does not elect hedge accounting treatment as there is no difference in the timing of gain or loss recognition on the hedging instrument and the hedged item.
All of the Company's derivative instruments are utilized for risk management purposes, and the Company does not use derivatives for speculative trading purposes. These contracts will mature over the next twelve months and are expected to impact earnings on or before maturity.

NOTE 11 – LONG-TERM DEBT
On July 27, 2021, the Company amended and extended its existing credit facility (as amended, the Second Amended and Restated Credit Agreement) with a syndicate of lenders by and among: the Company; JPMorgan Chase Bank, N.A. (JPMorgan), as administrative agent and collateral agent; JPMorgan, Wells Fargo Securities, LLC, BofA Securities Inc., RBC Capital Markets, PNC Capital Markets LLC and Mizuho Bank, Ltd., as joint lead arrangers and joint bookrunners; Santander Bank, N.A., U.S. Bank National Association, Fifth Third Bank National Association, Silicon Valley Bank and TD Bank, N.A., as co-documentation agents; and the lenders party thereto.
The Second Amended and Restated Credit Agreement provides for a five-year, $800.0 million senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million. The Company may elect to use the credit facility for general corporate purposes (including to finance the repurchase of shares of the Company's common stock). The commitments under the Second Amended and Restated Credit Agreement will expire on July 27, 2026, and any outstanding loans will be due on that date. During the six months ended September 30, 2024, the Company repaid $25.0 million of borrowings under the Second Amended and Restated Credit Agreement. At September 30, 2024, $75.0 million was outstanding under the Second Amended and Restated Credit Agreement.
On February 22, 2023, the Company entered into a First Amendment Agreement (First Amendment) of its Second Amended and Restated Credit Agreement with its syndicate of lenders. The Company entered into the First Amendment in order to remove and replace the LIBOR-based interest rate benchmark provisions for U.S. dollar-denominated loans with interest rate benchmark provisions for U.S. dollar-denominated loans based on a term secured overnight financing rate (SOFR).
The First Amendment provides that U.S. dollar-denominated advances under the Second Amended and Restated Credit Agreement will bear interest at a term SOFR rate plus a credit spread adjustment of 0.10% or an Alternate Base Rate (defined in a customary manner), at the option of the Company, plus a margin that ranges from 1.00% per annum for Alternate Base Rate loans and 2.00% per annum for term SOFR loans if the Company's consolidated gross leverage ratio is greater than 3.50 to 1.00, down to 0% per annum for Alternate Base Rate loans and 1.00% per annum for term SOFR loans if the Company's consolidated gross leverage ratio is equal to or less than 1.50 to 1.00. For the period from the delivery of the Company's financial statements for the quarter ended June 30, 2024, until the Company has delivered financial statements for the quarter ended September 30, 2024, the applicable margin will be 1.00% per annum for Term Benchmark Revolving loans and 0% per annum for Alternate Base Rate loans, and thereafter the applicable margin will vary depending on the Company's consolidated gross leverage ratio, ranging from 1.00% per annum for Alternate Base Rate loans and 2.00% per annum for Term Benchmark Revolving loans if the Company's consolidated gross leverage ratio is greater than 3.50 to 1.00, down to 0% per annum for Alternate Base Rate loans and 1.00% per annum for Term Benchmark Revolving loans if the Company's consolidated gross leverage ratio is equal to or less than 1.50 to 1.00.
The Company's consolidated gross leverage ratio is the ratio of its consolidated total debt compared to its consolidated EBITDA as defined in the Second Amended and Restated Credit Agreement (adjusted consolidated EBITDA). Adjusted consolidated EBITDA includes certain adjustments, including, without limitation, adjustments relating to extraordinary, unusual or non-recurring charges, certain restructuring charges, non-cash charges, certain transaction costs and expenses and certain pro forma adjustments in connection with material acquisitions and dispositions, all as set forth in detail in the Second Amended and Restated Credit Agreement.
Commitment fees will accrue on the daily unused amount of the credit facility. For the period from the delivery of the Company's financial statements for the quarter ended June 30, 2024, until the Company has delivered financial statements for the quarter ended September 30, 2024, the commitment fee will be 0.15% per annum, and thereafter the commitment fee will vary depending on the Company's consolidated gross leverage ratio, ranging from 0.30% per annum if the Company's consolidated gross leverage ratio is greater than 2.75 to 1.00, down to 0.15% per annum if the Company's consolidated gross leverage ratio is equal to or less than 1.50 to 1.00.
Letter of credit participation fees are payable to each lender providing the letter of credit sub-facility on the amount of such lender's letter of credit exposure, during the period from the closing date of the Second Amended and Restated Credit Agreement to, but excluding, the date which is the later of (i) the date on which such lender's commitment terminates or (ii) the date on which such lender ceases to have any letter of credit exposure, at a rate per annum equal to the applicable margin for term SOFR loans assuming such loans were outstanding during the period. Additionally, the Company will pay a fronting fee to each issuing bank in amounts to be agreed to between the Company and the applicable issuing bank.
Interest on Alternate Base Rate loans is payable at the end of each calendar quarter. Interest on term SOFR loans is payable at the end of each interest rate period or at the end of each three-month interval within an interest rate period if the
19

period is longer than three months. The Company may also prepay loans under the Second Amended and Restated Credit Agreement at any time, without penalty, subject to certain notice requirements.
The loans and other obligations under the credit facility are (a) guaranteed by each of the Company's wholly-owned material domestic restricted subsidiaries, subject to certain exceptions, and (b) are secured by substantially all of the assets of the Company and the subsidiary guarantors, including a pledge of all the capital stock of material subsidiaries held directly by the Company and the subsidiary guarantors (which pledge, in the case of any foreign subsidiary, is limited to 65% of the voting stock), subject to certain customary exceptions and limitations. The Second Amended and Restated Credit Agreement generally prohibits any other liens on the assets of the Company and its restricted subsidiaries, subject to certain exceptions as described in the Second Amended and Restated Credit Agreement.
The Second Amended and Restated Credit Agreement contains certain covenants applicable to the Company and its restricted subsidiaries, including, without limitation, limitations on additional indebtedness, liens, various fundamental changes, dividends and distributions, investments (including acquisitions), transactions with affiliates, asset sales, including sale-leaseback transactions, speculative hedge agreements, payment of junior financing, changes in business and other limitations customary in senior secured credit facilities. The Second Amended and Restated Credit Agreement requires the Company to maintain a certain consolidated net leverage ratio and removes the previous requirement under the Company's previous amended credit agreement that the Company maintain a minimum consolidated interest coverage ratio. The Company's consolidated net leverage ratio is the ratio of its Consolidated Total Debt minus the lesser of unrestricted cash and 125% of adjusted consolidated EBITDA compared to its adjusted consolidated EBITDA. The Company's maximum consolidated net leverage ratio is 4.00 to 1.00. These covenants and limitations are more fully described in the Second Amended and Restated Credit Agreement. At September 30, 2024, the Company was in compliance with all covenants, including the specified total consolidated net leverage ratio range of 4.00 to 1.00.
The Second Amended and Restated Credit Agreement provides that events of default will exist in certain circumstances, including failure to make payment of principal or interest on the loans when required, failure to perform certain obligations under the Second Amended and Restated Credit Agreement and related documents including a failure to meet the maximum total consolidated net leverage ratio covenant, defaults under certain other indebtedness, certain insolvency events, certain events arising under ERISA, a change of control and certain other events. Upon an event of default, the administrative agent with the consent of, or at the request of, the holders of more than 50% in principal amount of the loans and commitments, may terminate the commitments and accelerate the maturity of the loans and enforce certain other remedies under the Second Amended and Restated Credit Agreement and the other loan documents.
The Company had unamortized capitalized debt issuance costs, net of $2.0 million at September 30, 2024, which are being amortized over the life of the revolving credit facility. The unamortized capitalized debt issuance costs balance of $1.1 million was included as prepaid expenses and other current assets and a balance of $0.9 million was included as other assets in the Company's consolidated balance sheet at September 30, 2024.
NOTE 12 – RESTRUCTURING CHARGES
During the first quarter of fiscal year 2025, the Company implemented a voluntary separation program (VSP) for employees who met certain age and service requirements to reduce overall headcount. As a result of the related workforce reduction, during the three months and six months ended September 30, 2024, the Company recorded restructuring charges totaling $2.4 million and $19.0 million, respectively, related to one-time termination benefits for one hundred thirty-nine employees who voluntarily terminated their employment with the Company during the six months ended September 30, 2024. The Company estimates that approximately $0.6 million in restructuring charges will be recorded in the third quarter of fiscal year 2025 related to one-time termination benefits for three employees who are expected to voluntarily terminate their employment with the Company during the three months ending December 31, 2024. All one-time termination benefits are expected to be paid in full by the end of the fiscal year ending March 31, 2025.

NOTE 13 – LEASES
The Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets represent the Company's right to use an underlying asset for the duration of the lease term. Lease liabilities represent the Company's contractual obligation to make lease payments over the lease term. The Company's policy is to combine lease and non-lease components and to not recognize ROU assets and lease liabilities for short-term leases. Leases with an initial term of twelve months or less are classified as short-term leases. ROU assets are recorded and recognized at commencement for the lease liability amount, plus initial direct costs incurred less lease incentives received. Lease liabilities are recorded at the present value of future lease payments over the lease term at commencement. The discount rate used is generally the Company's estimated incremental borrowing rate unless the lessor's implicit rate is readily determinable. Incremental borrowing rates are calculated periodically to estimate the rate the Company would pay to borrow the funds necessary to obtain an asset of similar value over a similar term. Lease expenses relating to operating leases are recognized on a straight-line basis over the lease term.
The Company has operating leases for administrative, research and development, sales and marketing and manufacturing facilities and equipment under various non-cancelable lease agreements. The Company's leases have remaining lease terms ranging from 1 year to 7 years. The Company's lease terms may include options to extend or terminate the lease where it is reasonably certain that the Company will exercise those options. The Company considers several economic factors when making this determination, including but not limited to, the significance of leasehold improvements incurred in the office space, the difficulty in replacing the asset, underlying contractual obligations, or specific characteristics unique to a particular lease. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants.
The Company has asset retirement obligations (ARO) to return certain leased facilities to their original condition at the end of the respective lease term. The estimated fair value of these ARO liabilities is recognized in the period in which the liability is generated and a corresponding increase to the carrying value of the related asset is recorded and depreciated over the useful life of the asset. The Company's estimates of its ultimate AROs could change because of changes in regulations, the extent of environmental remediations required, the means of reclamation, cost estimates, exit or disposal activities or time period estimates. ARO liabilities totaled $2.3 million and $2.3 million at September 30, 2024 and March 31, 2024, respectively. There was a balance of $0.1 million included in accrued other and a balance of $2.2 million included in other long-term liabilities in the consolidated balance sheets at September 30, 2024, and a balance of $0.1 million included in accrued other and a balance of $2.2 million included in other long-term liabilities in the consolidated balance sheets at March 31, 2024. Accretion expense related to these liabilities was not material for any periods presented.
Most of the Company's lease agreements contain variable payments, primarily for common area maintenance (CAM), which are expensed as incurred and not included in the measurement of the ROU assets and lease liabilities.
The components of operating lease cost for the three and six months ended September 30, 2024 and 2023, respectively, were as follows (in thousands):

NOTE 14 – COMMITMENTS AND CONTINGENCIES
As previously disclosed, in March 2016, Packet Intelligence LLC (Packet Intelligence or Plaintiff) filed a Complaint against NetScout and two subsidiary entities in the United States District Court for the Eastern District of Texas asserting infringement of five United States patents. Plaintiff's Complaint alleged that legacy Tektronix GeoProbe products, including the G10 and GeoBlade products, infringed these patents. NetScout filed an Answer denying Plaintiff's allegations and asserting that Plaintiff's patents were, among other things, invalid, not infringed, and unenforceable due to inequitable conduct. In October 2017, a jury rendered a verdict finding in favor of the Plaintiff and that Plaintiff was entitled to $3.5 million for pre-suit damages and $2.3 million for post-suit damages. In September 2018, the Court entered judgment and "enhanced" the jury verdict in the amount of $2.8 million as a result of a jury finding. The judgment also awarded pre- and post-judgment interest, and a running royalty on the G10 and GeoBlade products until the expiration of the patents at issue, the last date being June 2022. Following the entry of final judgment, NetScout appealed, and in July 2020, the Court of Appeals for the Federal Circuit (Federal Circuit) issued a decision vacating the $3.5 million pre-suit damages award, affirming the $2.3 million post-suit damages award, vacating the $2.8 million enhancement award, and remanding to the district court to determine what, if any, enhancement should be awarded. In March 2021, NetScout filed a petition for a writ of certiorari to the United States Supreme Court, which was denied, challenging, among other issues, the basis for enhanced damages and the patentability of the claimed technology. On September 8 and 9, 2021, in proceedings initiated by third parties that did not involve NetScout, the Patent Trial and Appeal Board (PTAB) invalidated all the patent claims that were also asserted against NetScout in this case. After the PTAB decisions were issued, NetScout moved, among other things, to dismiss the case and enter judgment in its favor on the grounds that the PTAB decisions invalidating the asserted claims precluded Plaintiff from continuing to assert its patent infringement causes of action and from seeking damages from NetScout. The District Court denied NetScout’s motion with respect to its request to dismiss the case and enter judgment in its favor. The District Court entered an amended final judgment awarding Plaintiff $2.3 million in post-suit damages, $1.1 million in enhanced damages, pre- and post-judgment interest, and a running royalty on the G10 and GeoBlade products until the expiration of the patents at issue, the last expiration date being June 2022. On July 20, 2022, NetScout filed a notice of appeal to the Federal Circuit from, among other things, the amended final judgment. On May 2, 2024, in a separate action the Federal Circuit affirmed the PTAB decisions, which as a result found that all of the patent claims asserted by Packet Intelligence against NetScout were invalid. Also on May 2, 2024, the Federal Circuit ruled in NetScout's favor in its appeal, vacating the District Court's final judgment and remanding the case to the District Court to dismiss the case against NetScout as moot. As a result, during the year ended March 31, 2024, NetScout concluded that the risk of loss associated with damages that may result from this case was remote and recorded a $4.6 million reduction in contingent liabilities and legal fees. On June 26, 2024, the District Court issued its Order dismissing the case against NetScout.

NOTE 15 – PENSION BENEFIT PLANS
Certain of the Company's non-U.S. employees participate in noncontributory defined benefit pension plans. None of the Company's employees in the U.S. participate in any noncontributory defined benefit pension plans. In general, these plans are funded based on considerations relating to legal requirements, underlying asset returns, the plan's funded status, the anticipated deductibility of the contribution, local practices, market conditions, interest rates and other factors.
The following sets forth the components of the Company's net periodic pension cost of the noncontributory defined benefit pension plans recorded in operating expenses in the consolidated statements of operations for the three and six months ended September 30, 2024 and 2023, respectively, (in thousands):

Amortization of net gain(121)(218)(237)(452)
    Net periodic pension cost$184 $65 $360 $135 

Expected Contributions
During the six months ended September 30, 2024, the Company made contributions of $0.3 million to its defined benefit pension plans. During the fiscal year ending March 31, 2025, the Company's cash contribution requirements for its defined benefit pension plans are expected to be less than $1.0 million. As a majority of the participants within the Company's plans are all active employees, the benefit payments are not expected to be material in the foreseeable future.
NOTE 16 – TREASURY STOCK
On October 24, 2017, the Company's Board of Directors approved a share repurchase program that enabled the Company to repurchase up to twenty-five million shares of its common stock (2017 Share Repurchase Program). Through March 31, 2024, the Company repurchased all of the authorized 25,000,000 shares for $694.1 million in the open market under the 2017 Share Repurchase Program. The Company repurchased 1,117,777 shares for $31.2 million during the six months ended September 30, 2023 under the 2017 Share Repurchase Program.
On May 3, 2022, the Company's Board of Directors approved an additional share repurchase program that enables the Company to repurchase up to twenty-five million shares of its common stock (2022 Share Repurchase Program). The 2022 Share Repurchase Program became effective in the third quarter of fiscal year 2024 when the 2017 Share Repurchase Program was completed. The Company is not obligated to acquire any specific amount of common stock within any particular timeframe as a result of the 2022 Share Repurchase Program. Through September 30, 2024, the Company repurchased 1,976,721 shares for $41.6 million under the 2022 Share Repurchase Program. The Company repurchased 1,362,205 shares for $25.3 million under this share repurchase program during the six months ended September 30, 2024. At September 30, 2024, 23,023,279 shares of common stock remained available to be purchased under the current program.
In connection with the delivery of shares of the Company's common stock upon vesting of restricted stock units, the Company withheld 681,963 shares and 624,941 shares at a cost of $13.5 million and $18.7 million, respectively, related to minimum statutory tax withholding requirements on these restricted stock units during the six months ended September 30, 2024 and 2023, respectively. These withholding transactions do not fall under the share repurchase programs described above, and therefore do not reduce the number of shares that are available for repurchase under those programs.

Restricted stock units3,312 3,859 740 4,000 
Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic earnings per share. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding plus the dilutive effect, if any, of outstanding stock options, restricted shares and restricted stock units using the treasury stock method. The calculation of the dilutive effect of outstanding equity awards under the treasury stock method includes consideration of proceeds from the assumed exercise of stock options and unrecognized compensation expense as additional proceeds. As the Company incurred a net loss during the six months ended September 30, 2024, all outstanding restricted stock units and performance-based restricted stock units have an anti-dilutive effect and are therefore excluded from the computation of diluted weighted average shares outstanding.
NOTE 18 – INCOME TAXES
Generally, the Company's effective tax rate differs from the U.S. federal statutory income tax rate primarily due to foreign withholding taxes and U.S. taxation on foreign earnings, which are partially offset by research and development tax credits and the foreign derived intangible income deduction.
The Company's effective tax rates were 26.8% and 21.9% for the three months ended September 30, 2024 and 2023, respectively. The effective tax rate for the three months ended September 30, 2024 differed from the effective tax rate for the three months ended September 30, 2023 primarily related to an increase in the forecasted benefit of the foreign derived intangible deduction, offset by an increase in foreign withholding taxes.
The Company's effective tax rates were 1.6% and 22.0% for the six months ended September 30, 2024 and 2023, respectively. The effective tax rate for the six months ended September 30, 2024 differed from the effective tax rate for the six months ended September 30, 2023 primarily related to an increase in the forecasted benefit of the foreign derived intangible income deduction offset by an increase in foreign withholding taxes and goodwill impairment incurred during the six months ended September 30, 2024, which was not deductible for tax purposes.

NOTE 19 – SEGMENT AND GEOGRAPHIC INFORMATION
The Company reports revenues and income under one reportable segment.
The Company manages its business in the following geographic areas: United States, Europe, Asia and the rest of the world. The Company's policies mandate compliance with economic sanctions and the export controls.
Total revenue by geography is as follows (in thousands):

The United States revenue includes sales to resellers in the United States. These resellers fulfill customer orders and may subsequently ship the Company's products to international locations. Further, the Company determines the geography of its sales after considering where the contract originated. A majority of revenue attributable to locations outside of the United States is a result of export sales. Substantially all of the Company's identifiable assets are located in the United States.
NOTE 20 – SUBSEQUENT EVENTS
On October 4, 2024, the Company amended and restated the Second Amended and Restated Credit Agreement (as amended and restated, the Third Amended and Restated Credit Agreement). The Third Amended and Restated Credit Agreement provides for a new five-year $600.0 million senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million. The Company may elect to use the credit facility for working capital and other general corporate purposes, including to refinance revolving loans outstanding under the Second Amended and Restated Credit Agreement and to repurchase common stock. The commitments under the Third Amended and Restated Credit Agreement will expire on October 4, 2029, and any outstanding loans will be due on that date. In connection with the Third Amended and Restated Credit Agreement, the Company paid off all amounts outstanding under the existing credit agreement on October 4, 2024 by drawing down the same amount under the Third Amended and Restated Credit Agreement.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the condensed consolidated financial statements and notes thereto included elsewhere in this Quarterly Report and in our Annual Report on Form 10-K for the fiscal year ended March 31, 2024, filed with the Securities and Exchange Commission. This discussion contains forward-looking statements that involve risks and uncertainties. When reviewing the discussion below, you should keep in mind the substantial risks and uncertainties that could impact our business. In particular, we encourage you to review the risks and uncertainties described in Part I, Item 1A "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended March 31, 2024. These risks and uncertainties could cause actual results to differ significantly from those projected in forward-looking statements contained in this report or implied by past results and trends. Forward-looking statements are statements that attempt to forecast or anticipate future developments in our business, financial condition or results of operations. See the section titled "Cautionary Statement Concerning Forward-Looking Statements" that appears at the beginning of this Quarterly Report. These statements, like all statements in this report, speak only as of the date of this Quarterly Report (unless another date is indicated), and, except as required by law, we undertake no obligation to update or revise these statements in light of future developments.
Overview
We are an industry leader with four decades of experience in providing service assurance and cybersecurity solutions that are based on our pioneering deep packet inspection technology at scale, which is used by many Fortune 500 companies to protect their digital business services against disruption. Service providers and enterprises, including local, state and federal government agencies, rely on our solutions to achieve the visibility and protection necessary to optimize network performance, ensure the delivery of high-quality, mission-critical applications and services, gain timely insight into the end user experience and to protect their networks from attack. With our offerings, customers can quickly, efficiently and effectively identify and resolve issues that result in downtime, interruptions to services, poor service quality or compromised data, thereby reducing meantime-to-resolution of issues and driving compelling returns on their investments in their networks and broader technology initiatives. Some of the more significant technology trends and catalysts for our business include the evolution of customers' digital transformation initiatives such as the migration to cloud environments, the rapidly evolving cybersecurity threat landscape, artificial intelligence and business analytics advancements, and the 5G technology evolution in both the service provider and enterprise customer verticals.
Our operating results are influenced by a number of factors, including, but not limited to, the volume, mix, and quantity of products and services sold, pricing, costs and availability of materials used in our products, growth in employee-related costs, including commissions, and the expansion of our operations. Factors that affect our ability to maximize our operating results include, but are not limited to, our ability to introduce and enhance existing products, the marketplace acceptance of those new or enhanced products, continued expansion into international markets, expansion into new or adjacent markets, development of strategic partnerships, competition, successful acquisition and integration efforts, and our ability to control costs, and make improvements in a highly competitive industry.
Global and Macroeconomic Conditions
We continue to closely monitor current global and macroeconomic conditions, including the impacts of the ongoing war in Ukraine and the Middle East, global geopolitical tension, stock market volatility, industry-specific capital spending trends, exchange rate fluctuations, inflation, interest rates, and the risk of a recession, including the manner and extent to which they have impacted and could continue to impact our business, customers, employees, supply chain, and distribution network. The full extent of the impacts of these global and macroeconomic conditions remain uncertain. In response to the war
in Ukraine, we ceased business operations in Russia, including sales, support on existing contracts and professional services.
The macroeconomic environment remains challenging with constrained customer spending and we expect this to persist for the remainder of fiscal year 2025. As a result, we have continued our efforts to manage discretionary costs and align spending with the current environment while we continue to execute on our long-term strategic plans.
Though we continue to monitor the impacts of evolving global and macroeconomic conditions on our business, we believe our current cash reserves and access to capital through our revolving credit facility leave us well-positioned to manage our business in today's environment. We expect net cash provided by operations combined with cash, cash equivalents, marketable securities and investments and borrowing availability under our revolving credit facility to provide sufficient liquidity to fund current obligations, capital spending, debt service requirements and working capital requirements over at least the next twelve months. We continue to take actions to manage costs and increase productivity throughout our company, including managing discretionary spending and hiring activities, but are continuing to invest in areas that advance our business for the future. In addition to our cash equivalents, based on covenant levels at September 30, 2024, we had an incremental $725 million available to us under our revolving credit facility. On October 4, 2024, we amended and extended the Second Amended and Restated Credit Agreement, which decreased the revolving credit facility from $800 million to $600 million and
26

reduced the incremental amount available to us under our revolving credit facility to $525 million. For further information, see Note 20 contained in the "Notes to Consolidated Financial Statements" included in Part 1 of this quarterly report on Form 10-Q.
Results Overview
Total revenue decreased $42.3 million, or 10%, for the six months ended September 30, 2024 as compared to total revenue for the six months ended September 30, 2023, which benefited from approximately $48 million of backlog-related revenue. Excluding this factor, revenue would have increased on a year over year basis. The decrease in total revenue for the six months ended September 30, 2024 as compared to total revenue for the six months ended September 30, 2023 was a result of lower revenue from both service provider and enterprise customers from service assurance offerings, including radio frequency propagation modeling projects, as a result of industry-specific capital spending constraints, as well as a decrease in revenue from service provider customers from cybersecurity offerings.
Our gross profit percentage decreased by one percentage point to 76% during the six months ended September 30, 2024, as compared with the six months ended September 30, 2023 primarily due to lower sales volume of higher margin products and services.
Net loss for the six months ended September 30, 2024 was $434.3 million, as compared with net income for the six months ended September 30, 2023 of $17.3 million. The increase of $451.6 million in net loss was primarily due to a $427.0 million goodwill impairment charge, a $42.3 million decrease in revenue, a $19.0 million increase from restructuring charges due to the voluntary separation program, a $2.7 million increase in expenses related to trade shows, user conferences, and other events, a $1.0 million increase from software licenses, and a $1.0 million increase in foreign exchange expense. These increases to net loss were partially offset by an $11.9 million increase in income tax benefit, a $7.6 million increase in other income from the change in fair value of a foreign equity investment, a $5.5 million decrease in employee related expenses as a result of a decrease in headcount, partially offset by an increase in variable incentive compensation, a $3.6 million decrease in commissions expense, a $3.5 million decrease in direct material costs, a $3.5 million decrease in amortization expense, a $2.3 million decrease from depreciation expense, and a $1.6 million decrease in contractor fees.
At September 30, 2024, we had cash, cash equivalents, marketable securities and investments (current and non-current) of $401.9 million. This represents a decrease of $22.2 million from $424.1 million at March 31, 2024. This decrease was primarily due to $25.3 million used to repurchase shares of our common stock, $25.0 million used to repay long-term debt, $13.5 million used for tax withholdings on restricted stock units, $2.2 million used for capital expenditures, and $1.3 million used to acquire technology licenses, partially offset by $34.7 million of net cash provided by operations, and an $8.3 million increase from the change in fair value of an equity instrument during the six months ended September 30, 2024.
Use of Non-GAAP Financial Measures
We supplement the United States generally accepted accounting principles (GAAP) financial measures we report in quarterly and annual earnings announcements, investor presentations and other investor communications by reporting the following non-GAAP measures: non-GAAP gross profit, non-GAAP income from operations, non-GAAP net income, non-GAAP net income per share (diluted) and non-GAAP earnings before interest and other expense, income taxes, depreciation, and amortization (EBITDA) from operations. Non-GAAP gross profit removes expenses related to the amortization of acquired intangible assets, share-based compensation expense, and acquisition-related depreciation expense. Non-GAAP income from operations removes the aforementioned adjustments to non-GAAP gross profit and also removes legal expenses related to civil judgments, gain on the divestiture of a business, goodwill impairment charges, and restructuring charges. Non-GAAP net income removes the foregoing adjustments related to non-GAAP income from operations, and also removes change in the fair value of derivative instrument, net of related income tax effects. Non-GAAP EBITDA from operations removes the aforementioned items related to non-GAAP income from operations and also removes non-acquisition related depreciation expense.
These non-GAAP measures are not in accordance with GAAP, should not be considered an alternative for measures prepared in accordance with GAAP (revenue, gross profit, operating margin, net income and diluted net income per share), and may have limitations because they do not reflect all our results of operations as determined in accordance with GAAP. These non-GAAP measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures. The presentation of non-GAAP information is not meant to be considered superior to, in isolation from, or as a substitute for results prepared in accordance with GAAP.
Management believes these non-GAAP financial measures will enhance the reader's overall understanding of our current financial performance and our prospects for the future by providing a higher degree of transparency for certain financial measures and providing a level of disclosure that helps investors understand how we plan and measure our business. We believe that providing these non-GAAP measures affords investors a view of our operating results that may be more easily compared to peer companies and also enables investors to consider our operating results on both a GAAP and non-GAAP basis during and
27

following the integration period of our acquisitions. Presenting the GAAP measures on their own may not be indicative of our core operating results. Furthermore, management believes that the presentation of non-GAAP measures when shown in conjunction with the corresponding GAAP measures provides useful information to management and investors regarding present and future business trends relating to our financial condition and results of operations.

Critical Accounting Policies and Estimates
 Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with GAAP consistently applied. The preparation of these consolidated financial statements requires us to make significant estimates and judgments that affect the amounts reported in our consolidated financial statements and the accompanying notes. These items are regularly monitored and analyzed by management for changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are recorded in the period in which they become known. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from our estimates.
While all of our accounting policies impact the consolidated financial statements, certain policies are viewed to be critical. Critical accounting policies are those that are both most important to the portrayal of our financial condition and results of operations and that require management's most subjective or complex judgments and estimates. We consider the following accounting policies to be critical in fully understanding and evaluating our financial results:
revenue recognition; and
valuation of goodwill, intangible assets and other acquisition accounting items.
Please refer to the critical accounting policies set forth in our Annual Report on Form 10-K for the fiscal year ended March 31, 2024, filed with the Securities and Exchange Commission (SEC) on May 16, 2024, for a description of all of our critical accounting policies and estimates.

The service gross profit percentage decreased by three percentage points to 74% during the three months ended September 30, 2024 as compared with the three months ended September 30, 2023. The 9%, or $7.8 million, decrease in service gross profit is attributable to the 5%, or $6.2 million decrease in service revenue, and the 6%, or $1.7 million, increase in cost of service revenue.
Gross profit. Our gross profit decreased 3%, or $4.7 million, during the three months ended September 30, 2024 when compared with the three months ended September 30, 2023. This decrease is attributable to the decrease in revenue of 3%, or $5.7 million, partially offset by the 2%, or $1.0 million, decrease in cost of revenue. The gross profit percentage remained flat at 78% for the three months ended September 30, 2024 as compared with the three months ended September 30, 2023.

Research and development. Research and development expenses consist primarily of personnel expenses, fees for outside consultants, overhead and related expenses associated with the development of new products and the enhancement of existing products.
The 2%, or $0.8 million, increase in research and development expenses for the three months ended September 30, 2024 compared to the same period last year was primarily due to a $1.2 million increase in employee-related costs associated with an increase in variable incentive compensation partially offset by a decrease in cost due to a reduction in headcount, and a $0.6 million increase in allocated overhead. These increases were partially offset by a $0.6 million decrease from depreciation expense.
Sales and marketing. Sales and marketing expenses consist primarily of personnel expenses and commissions, overhead and other expenses associated with selling activities and marketing programs such as trade shows, seminars, advertising and new product launch activities.
The $0.3 million increase in total sales and marketing expenses for the three months ended September 30, 2024 compared to the same period last year was primarily due to a $3.6 million increase related to trade shows and other events. This increase was partially offset by a $3.5 million decrease in employee-related costs associated with a decrease in variable incentive compensation as well as a decrease in cost due to a reduction in headcount, and a $0.6 million decrease in commissions expense.
General and administrative. General and administrative expenses consist primarily of personnel expenses for executive, financial, legal and human resource employees, overhead and other corporate expenditures.
The 5%, or $1.1 million, increase in general and administrative expenses for the three months ended September 30, 2024 compared to the same period last year was primarily due to a $1.6 million increase in employee-related costs associated with an increase in variable incentive compensation.
Amortization of acquired intangible assets. Amortization of acquired intangible assets consists primarily of amortization of customer relationships, definite-lived trademarks and trade names, and developed technology related to our acquisitions of Danaher Corporation's communications business (Comms Transaction), Network General Corporation, Avvasi Inc. and Efflux Systems, Inc.
The 7%, or $0.9 million, decrease in amortization of acquired intangible assets was largely due to a decrease in the amortization of intangible assets acquired as part of the Comms Transaction and the Network General Corporation transaction.
Restructuring charges. During the first quarter of fiscal year 2025, we implemented a voluntary separation program (VSP) for employees who met certain age and service requirements to reduce overall headcount. As a result of the related workforce reduction, during the three months ended September 30, 2024, we recorded additional restructuring charges totaling $2.4 million related to one-time termination benefits for twenty-three employees who voluntarily terminated their employment with us during the three months ended September 30, 2024.
Gain on Divestiture of Business. During the three months ended September 30, 2023, we recorded a $3.8 million gain on the divestiture of the Test Optimization business.

The 252%, or $3.0 million, change in interest and other income (expense), net for the three months ended September 30, 2024 compared to the same period last year was primarily due to a $2.1 million increase in foreign exchange expense, and a $0.9 million decrease from the change in fair value of the equity investment in Napatech.
Income Tax Expense. The effective tax rates were 26.8% and 21.9% for the three months ended September 30, 2024 and 2023, respectively. The effective tax rate for the three months ended September 30, 2024 differed from the effective tax rate for the three months ended September 30, 2023, primarily related to an increase in the forecasted benefit of the foreign derived intangible deduction, offset by an increase in foreign withholding taxes.

Product. The 19%, or $33.0 million, decrease in product revenue compared with the same period last year was due to a decrease in revenue from both service provider and enterprise customers from service assurance offerings, including radio frequency propagation modeling projects, as a result of industry-specific capital spending constraints, as well as a decrease in revenue from service provider customers from cybersecurity offerings. The results for the six months ended September 30, 2023 benefited from approximately $48 million of backlog-related revenue. Excluding backlog-related revenue, total revenue for the six months ended September 30, 2024 compared with the same period last year would have increased year over year.
Service. The 4%, or $9.3 million, decrease in service revenue compared with the same period last year was primarily due to a decrease in revenue from maintenance contracts as well as professional service contracts.

Product. The 22%, or $7.3 million, decrease in cost of product revenue for the six months ended September 30, 2024 compared to the same period last year was primarily due to a $3.5 million decrease in direct material costs, a $1.5 million decrease in the amortization of intangible assets, a $0.9 million decrease in costs related to the delivery of radio frequency propagation modeling projects, a $0.8 million decrease in inventory related expenses, and a $0.6 million decrease in employee-related costs associated with the timing of certain projects. The product gross profit percentage increased by one percentage point to 82% during the six months ended September 30, 2024 when compared to the six months ended September 30, 2023. The 18%, or $25.7 million, decrease in product gross profit is attributable to the 19%, or $33.0 million, decrease in product revenue, partially offset by the 22%, or $7.3 million, decrease in cost of product revenue.
Service. The $0.3 million increase in cost of service revenue for the six months ended September 30, 2024 compared to the same period last year was primarily due to a $0.9 million increase in employee-related expenses largely due to an increase in variable incentive compensation partially offset by a decrease in costs due to a reduction in headcount, and a $0.5 million increase in contractor fees. These increases were partially offset by a $0.6 million decrease in cost of materials used to support customers under service contracts. The service gross profit percentage decreased by one percentage point to 73% for the six months ended September 30, 2024 when compared to the six months ended September 30, 2023. The 6%, or $9.6 million, decrease in service gross profit is attributable to the 4%, or $9.3 million decrease in service revenue, and the $0.3 million increase in cost of service revenue.
Gross profit. Our gross profit for the six months ended September 30, 2024 decreased 11%, or $35.2 million, compared to the same period last year. This decrease is primarily attributable to the decrease in revenue of 10%, or $42.3 million, partially offset by the 8%, or $7.0 million, decrease in cost of revenue. The gross profit percentage decreased by one percentage point to 76% for the six months ended September 30, 2024 when compared to the six months ended September 30, 2023.

Research and development. The 3%, or $2.3 million, decrease in research and development expenses for the six months ended September 30, 2024 compared to the same period last year was primarily due to a $1.2 million decrease in employee-related expenses largely due to a decrease in headcount partially offset by an increase in variable incentive compensation, a $1.2 million decrease from depreciation expense, and a $0.5 million decrease in contractor fees. These decreases were offset by a $0.9 million increase in allocated overhead.
Sales and marketing. The 6%, or $8.4 million, decrease in sales and marketing expenses for the six months ended September 30, 2024 compared to the same period last year was primarily due to a $6.5 million decrease in employee-related expenses largely due to a decrease in headcount, a $3.6 million decrease in commissions expense, and a $0.7 million decrease in advertising expense. These decreases were partially offset by a $2.7 million increase related to trade shows and other events.
General and administrative. The 3%, or $1.5 million, decrease in general and administrative expenses for the six months ended September 30, 2024 compared to the same period last year was primarily due to a $1.4 million decrease in contractor fees, a $0.7 million decrease from depreciation expense, a $0.6 million decrease in business taxes, and a $0.5 million decrease in allocated overhead. These decreases were partially offset by a $1.2 million increase in employee-related expenses largely due to an increase in variable incentive compensation, a $0.5 million increase in legal fees, and a $0.5 million increase in accounting related expenses.
Amortization of acquired intangible assets. Amortization of acquired intangible assets consists primarily of amortization of customer relationships, definite-lived trademark and tradenames, and developed technology related to our acquisitions of the Comms Transact, Network General Corporation, Avvasi, Inc. and Efflux Systems, Inc.
The 8%, or $2.0 million, decrease in amortization of acquired intangible assets for the six months ended September 30, 2024 compared to the same period last year was largely due to a decrease in the amortization of intangible assets related to the Comms Transaction and Network General Corporation.
Restructuring charges. During the first quarter of fiscal year 2025, we implemented a voluntary separation program (VSP) for employees who met certain age and service requirements to reduce overall headcount. As a result of the related workforce reduction, during the six months ended September 30, 2024, we recorded restructuring charges totaling $19.0 million related to one-time termination benefits for one hundred thirty-nine employees who voluntarily terminated their employment with us during that period.
Goodwill impairment. During fiscal year 2024, we recorded $217.3 million in goodwill impairment charges as a result of the sustained decline in our stock price and overall market capitalization. During the first quarter of fiscal year 2025, due to the continued decrease in our stock price and overall market capitalization, along with other qualitative considerations including the continued impact from the conditions in the macroeconomic environment, it was determined a Triggering Event occurred, indicating goodwill may be impaired. Accordingly, we conducted a quantitative impairment test of our goodwill at June 30, 2024. We estimated the implied fair value of our goodwill using a market approach. As a result of the quantitative impairment test performed during the first quarter of fiscal year 2025, we determined goodwill was impaired and recorded a goodwill impairment charge of $427.0 million during the three months ended June 30, 2024. The additional impairment charge recorded in the first quarter of fiscal year 2025 was primarily due to the continued decrease in our stock price from March 31, 2024 to June 30, 2024, an increase in our weighted-average cost of capital, and the refinement to the expected cost synergies that could
37

be realized by a hypothetical buyer as a result of the VSP we implemented in the first quarter of fiscal year 2025, which impacted the company-specific control premium used to determine the fair value of the reporting unit under the market approach. We expect that these restructuring efforts will generate net annual run-rate savings of approximately $25 million to $27 million, of which we expect that approximately $18 million to $19 million will be realized in the remainder of fiscal year 2025. At September 30, 2024, the Company performed a Triggering Event assessment and concluded no event or circumstances occurred that indicated goodwill was further impaired.
The key assumption in the market approach was the company-specific control premium, which was estimated using expected synergies that would be realized by a hypothetical buyer. We also compared its implied control premium to recent control premiums paid in the industry, as evidenced by guideline public company comparable transactions. This information corroborated that the company-specific control premium was within the range of premiums for other companies operating in the industry. Changes in the estimates or assumptions used in its quantitative impairment test could materially affect the determination of fair value and the associated goodwill impairment assessment. Potential events and circumstances that could have an adverse impact on our estimates and assumptions include, but are not limited to, continued increases in costs, and high interest rates and other macroeconomic factors. An increase or decrease of 1% in the company-specific control premium used in the determination of the fair value of the reporting unit under the market approach would have resulted in an increase or decrease in the goodwill impairment recorded during the six months ended September 30, 2024 of approximately $13.0 million.
Gain on Divestiture of Business. During the six months ended September 30, 2023, we recorded a $3.8 million gain on the divestiture of the Test Optimization business.

The 1,342%, or $7.3 million, increase in interest and other income (expense), net was primarily due to a $7.6 million increase from the change in fair value of the equity investment in Napatech, a $0.8 million increase in interest income, and a $0.5 million decrease in interest expense due to debt repayments on the credit facility in May 2024, partially offset by an increase in the average interest rate on the credit facility. These increases were partially offset by a $1.0 million increase in foreign exchange expense during the six months ended September 30, 2024, when compared to the six months ended September 30, 2023, and a $0.5 million decrease in other income.
Income Tax Expense (Benefit). Our effective tax rates were 1.6% and 22.0% for the six months ended September 30, 2024 and 2023, respectively. The effective tax rate for the six months ended September 30, 2024 differed from the effective rate for the six months ended September 30, 2023, primarily related to an increase in the forecasted benefit of the foreign derived intangible income deduction offset by an increase in foreign withholding taxes and goodwill impairment incurred during the six months ended September 30, 2024, which was not deductible for tax purposes.

This decrease was primarily due to $25.3 million used to repurchase shares of our common stock, $25.0 million used to repay long-term debt, $13.5 million used for tax withholdings on restricted stock units, $2.2 million used for capital expenditures, and $1.3 million used to acquire technology licenses, partially offset by $34.7 million of net cash provided by operations, and an $8.3 million increase from the change in fair value of an equity instrument during the six months ended September 30, 2024. Cash and short-term investments held outside of the United States was approximately $181.1 million.

Cash provided by operating activities was $34.7 million during the six months ended September 30, 2024, compared with $48.7 million of cash used in operating activities during the six months ended September 30, 2023. The $83.4 million change was due in part to a $427.0 million goodwill impairment charge recorded during the six months ended September 30, 2024, an $82.6 million increase from accounts receivable, a $43.6 million increase from accrued compensation and other expenses, a $3.8 million increase related to the gain recorded in the six months ended September 30, 2023 for the divestiture of a business, a $3.1 million increase from income taxes payable, a $3.0 million increase from prepaid expenses and other assets, and a $0.6 million increase from accounts payable. These increases were partially offset by a $451.6 million decrease from the change in net income (loss), a $7.8 million decrease from deferred revenue, a $7.6 million decrease from the change in the fair value of an equity investment, a $5.9 million decrease from depreciation and amortization expense, a $3.4 million decrease in deferred income taxes, a $2.2 million decrease from share-based compensation, and a $2.0 million decrease from inventories during the six months ended September 30, 2024 as compared with the six months ended September 30, 2023.

Cash provided by investing activities was $0.9 million during the six months ended September 30, 2024, compared with $7.0 million of cash used in investing activities during the six months ended September 30, 2023. The $7.9 million change was due in part to a $16.0 million increase in cash inflow from marketable securities related to a $20.9 million decrease in the purchase of marketable securities and investments, partially offset by a decrease of $4.9 million in proceeds from the sales and maturity of marketable securities during the six months ended September 30, 2024 when compared with the six months ended September 30, 2023. In addition, cash used to purchase fixed assets decreased $1.3 million during the six months ended September 30, 2024, compared with the six months ended September 30, 2023. These increases to cash inflow were partially offset by an $8.3 million decrease in proceeds from the divestiture of the Test Optimization business during the six months ended September 30, 2023, and a $1.3 million increase in cash used to acquire technology licenses during the six months ended September 30, 2024.

During the six months ended September 30, 2024, we repurchased a total of 1,362,205 shares for $25.3 million in the open market under the 2022 Share Repurchase Program.
In connection with the delivery of our common stock upon vesting of restricted stock units, we withheld 681,963 and 624,941 shares at a cost of $13.5 million and $18.7 million related to minimum statutory tax withholding requirements on these restricted stock units during the six months ended September 30, 2024 and 2023, respectively. These withholding transactions do not fall under the repurchase program described above, and therefore do not reduce the number of shares that are available for repurchase under that program.
During the six months ended September 30, 2024, we repaid $25.0 million of borrowings under the Second Amended and Restated Credit Agreement.

Sources of Cash and Cash Requirements
Credit Facility
On July 27, 2021, we amended and extended our existing credit facility (as amended, the Second Amended and Restated Credit Agreement) with a syndicate of lenders by and among: the Company; JPMorgan Chase Bank, N.A. (JPMorgan), as administrative agent and collateral agent; JPMorgan, Wells Fargo Securities, LLC, BofA Securities Inc., RBC Capital Markets, PNC Capital Markets LLC and Mizuho Bank, Ltd., as joint lead arrangers and joint bookrunners; Santander Bank, N.A., U.S. Bank National Association, Fifth Third Bank National Association, Silicon Valley Bank and TD Bank, N.A., as co-documentation agents; and the lenders party thereto.
The Second Amended and Restated Credit Agreement provides for a five-year, $800.0 million senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million. We may elect to use the credit facility for general corporate purposes (including to finance the repurchase of shares of our common stock). The commitments under the Second Amended and Restated Credit Agreement will expire on July 27, 2026, and any outstanding loans will be due on that date. During the six months ended September 30, 2024, we repaid $25.0 million of borrowings under the Second Amended and Restated Credit Agreement. At September 30, 2024, $75.0 million was outstanding under the Second Amended and Restated Credit Agreement.
On February 22, 2023, we entered into a First Amendment Agreement (First Amendment) of our Second Amended and Restated Credit Agreement with a syndicate of lenders. We entered into the First Amendment in order to remove and replace the LIBOR-based interest rate benchmark provisions for U.S. dollar-denominated loans with interest rate benchmark provisions for U.S. dollar-denominated loans based on a term secured overnight financing rate (SOFR).
The First Amendment provides that U.S. dollar-denominated advances under the Second Amended and Restated Credit Agreement will bear interest at a term SOFR rate plus a credit spread adjustment of 0.10% or an Alternate Base Rate (defined in a customary manner), at the option of NetScout, plus a margin that ranges from 1.00% per annum for Alternate Base Rate loans and 2.00% per annum for term SOFR loans if our consolidated gross leverage ratio is greater than 3.50 to 1.00, down to 0% per annum for Alternate Base Rate loans and 1.00% per annum for term SOFR loans if our consolidated gross leverage ratio is equal to or less than 1.50 to 1.00. For the period from the delivery of our financial statements for the quarter ended June 30, 2024, until we have delivered financial statements for the quarter ended September 30, 2024, the applicable margin will be 1.00% per annum for Term Benchmark Revolving loans and 0% per annum for Alternate Base Rate loans, and thereafter the applicable margin will vary depending on our consolidated gross leverage ratio, ranging from 1.00% per annum for Alternate Base Rate loans and 2.00% per annum for Term Benchmark Revolving loans if our consolidated gross leverage ratio is greater than 3.50 to 1.00, down to 0% per annum for Alternate Base Rate loans and 1.00% per annum for Term Benchmark Revolving loans if our consolidated gross leverage ratio is equal to or less than 1.50 to 1.00.
Our consolidated gross leverage ratio is the ratio of our consolidated total debt compared to our consolidated EBITDA as defined in the Second Amended and Restated Credit Agreement (adjusted consolidated EBITDA). Adjusted consolidated EBITDA includes certain adjustments, including, without limitation, adjustments relating to extraordinary, unusual or non-recurring charges, certain restructuring charges, non-cash charges, certain transaction costs and expenses and certain pro forma adjustments in connection with material acquisitions and dispositions, all as set forth in detail in the Second Amended and Restated Credit Agreement.
Commitment fees will accrue on the daily unused amount of the credit facility. For the period from the delivery of our financial statements for the quarter ended June 30, 2024, until we have delivered financial statements for the quarter ended September 30, 2024, the commitment fee will be 0.15% per annum, and thereafter the commitment fee will vary depending on our consolidated gross leverage ratio, ranging from 0.30% per annum if our consolidated gross leverage ratio is greater than 2.75 to 1.00, down to 0.15% per annum if our consolidated gross leverage ratio is equal to or less than 1.50 to 1.00.
Letter of credit participation fees are payable to each lender providing the letter of credit sub-facility on the amount of such lender's letter of credit exposure, during the period from the closing date of the Second Amended and Restated Credit Agreement to, but excluding, the date which is the later of (i) the date on which such lender's commitment terminates or (ii) the date on which such lender ceases to have any letter of credit exposure, at a rate per annum equal to the applicable margin for term SOFR loans assuming such loans were outstanding during the period. Additionally, we will pay a fronting fee to each issuing bank in amounts to be agreed to between us and the applicable issuing bank.
Interest on Alternate Base Rate loans is payable at the end of each calendar quarter. Interest on term SOFR loans is payable at the end of each interest rate period or at the end of each three-month interval within an interest rate period if the period is longer than three months. We may also prepay loans under the Second Amended and Restated Credit Agreement at any time, without penalty, subject to certain notice requirements.
The loans and other obligations under the credit facility are (a) guaranteed by each of our wholly-owned material domestic restricted subsidiaries, subject to certain exceptions, and (b) are secured by substantially all of the assets of us and the
41

subsidiary guarantors, including a pledge of all the capital stock of material subsidiaries held directly by us and the subsidiary guarantors (which pledge, in the case of any foreign subsidiary, is limited to 65% of the voting stock), subject to certain customary exceptions and limitations. The Second Amended and Restated Credit Agreement generally prohibits any other liens on the assets of NetScout and our restricted subsidiaries, subject to certain exceptions as described in the Second Amended and Restated Credit Agreement.
The Second Amended and Restated Credit Agreement contains certain covenants applicable to us and our restricted subsidiaries, including, without limitation, limitations on additional indebtedness, liens, various fundamental changes, dividends and distributions, investments (including acquisitions), transactions with affiliates, asset sales, including sale-leaseback transactions, speculative hedge agreements, payment of junior financing, changes in business and other limitations customary in senior secured credit facilities. The Second Amended and Restated Credit Agreement requires us to maintain a certain consolidated net leverage ratio and removes the previous requirement under our previous amended credit agreement that we maintain a minimum consolidated interest coverage ratio. Our consolidated net leverage ratio is the ratio of our Consolidated Total Debt minus the lesser of unrestricted cash and 125% of adjusted consolidated EBITDA compared to our adjusted consolidated EBITDA. Our maximum consolidated net leverage ratio is 4.00 to 1.00. These covenants and limitations are more fully described in the Second Amended and Restated Credit Agreement. At September 30, 2024, we were in compliance with all covenants, including the specified total consolidated net leverage ratio range of 4.00 to 1.00.
The Second Amended and Restated Credit Agreement provides that events of default will exist in certain circumstances, including failure to make payment of principal or interest on the loans when required, failure to perform certain obligations under the Second Amended and Restated Credit Agreement and related documents including a failure to meet the maximum total consolidated net leverage ratio covenant, defaults under certain other indebtedness, certain insolvency events, certain events arising under ERISA, a change of control and certain other events. Upon an event of default, the administrative agent with the consent of, or at the request of, the holders of more than 50% in principal amount of the loans and commitments, may terminate the commitments and accelerate the maturity of the loans and enforce certain other remedies under the Second Amended and Restated Credit Agreement and the other loan documents.
We had unamortized capitalized debt issuance costs, net of $2.0 million at September 30, 2024, which are being amortized over the life of the revolving credit facility. The unamortized capitalized debt issuance costs balance of $1.1 million was included as prepaid expenses and other current assets and a balance of $0.9 million was included as other assets in our consolidated balance sheet at September 30, 2024. On October 4, 2024, we amended and extended the Second Amended and Restated Credit Agreement (as amended and restated, the Third Amended and Restated Credit Agreement), which decreased the incremental amount available to us under our revolving credit facility to $525 million. For further information, see Note 20 contained in the "Notes to Consolidated Financial Statements" included in Part 1 of this quarterly report on Form 10-Q.
Cash Requirements
We are actively managing the business to generate cash flow and believe that we currently have adequate liquidity. We believe that these factors will allow us to meet our anticipated funding requirements for at least the next twelve months.
We have contractual obligations for long-term debt, operating leases, unconditional purchase obligations, pension benefits plans and certain other long-term liabilities. Our obligations related to these items are described further within Management’s Discussion and Analysis of Financial Condition and Results of Operations within our Annual Report filed on Form 10-K. We expect net cash provided by operating activities combined with cash, cash equivalents, marketable securities and investments and borrowing availability under our revolving credit facility will provide sufficient liquidity to fund current obligations, capital spending, debt service requirements and working capital requirements over at least the next twelve months. We believe we will meet longer-term expected future cash requirements and obligations through a combination of cash flows from operating activities, available cash balances, and our revolving credit facility. However, macroeconomic conditions, including high inflation and interest rates, and a potential recession, could increase our anticipated funding requirements or make it more difficult for us to access capital.
A portion of our cash may be used to acquire or invest in complementary businesses or products, to obtain the right to use complementary technologies, to repay borrowings under our Third Amended and Restated Credit Agreement, or to repurchase shares of our common stock through our stock repurchase programs. From time to time, in the ordinary course of business, we evaluate potential acquisitions of such businesses, products or technologies. If our existing sources of liquidity are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or debt securities. Macroeconomic conditions, including high interest rates and volatility in the capital markets, may make it difficult for us to secure additional financing on favorable terms or at all. Any sale of additional equity or debt securities could result in additional dilution to our stockholders.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk. We hold our cash, cash equivalents and investments for working capital purposes. Some of the securities we invest in are subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, we maintain our portfolio of cash, cash equivalents and investments in a variety of securities, including money market funds and government debt securities. The risk associated with fluctuating interest rates is limited to our investment portfolio. Due to the short-term nature of these instruments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. Declines in interest rates, however, would reduce future interest income. The effect of a hypothetical 10% increase or decrease in overall interest rates would not have had a material impact on our operating results or the total fair value of the portfolio.
We are exposed to market risks related to fluctuations in interest rates related to our credit facility. At September 30, 2024, we owed $75.0 million on this loan with an interest rate of 5.95%. A sensitivity analysis was performed on the outstanding portion of our debt obligation as of September 30, 2024. Should the current weighted-average interest rate increase or decrease by 10%, the resulting annual increase or decrease to interest expense would be approximately $446 thousand as of September 30, 2024.
Foreign Currency Exchange Risk. As a result of our foreign operations, we face exposure to movements in foreign currency exchange rates, primarily the Euro, British Pound, Canadian Dollar and Indian Rupee. The current exposures arise primarily from expenses denominated in foreign currencies. We currently engage in foreign currency hedging activities in order to limit these exposures. Periodically, we also enter into forward contracts to manage exchange risk associated with third-party transactions and for which we do not elect hedge accounting treatment. We do not use derivative financial instruments for speculative trading purposes.
At September 30, 2024, we had foreign currency forward contracts designated as hedging instruments with notional amounts totaling $10.2 million. The valuation of outstanding foreign currency forward contracts at September 30, 2024 resulted in a liability balance of $6 thousand, reflecting unfavorable contract rates in comparison to current market rates at this date and an asset balance of $132 thousand, reflecting favorable rates in comparison to current market rates at this date. At March 31, 2024, we had foreign currency forward contracts designated as hedging instruments with notional amounts totaling $11.7 million. The valuation of outstanding foreign currency forward contracts at March 31, 2024 resulted in a liability balance of $74 thousand, reflecting unfavorable contract rates in comparison to current market rates and an asset balance of $11 thousand, reflecting favorable rates in comparison to current market rates at this date. The effect of a hypothetical 10% change in foreign currency exchange rates applicable to our business would not have a material impact on our historical consolidated financial statements. As our international operations grow, we will continue to reassess our approach to manage our risk relating to fluctuations in currency rates.
Item 4.  Controls and Procedures
At September 30, 2024, NetScout, under the supervision and with the participation of our management, including the Company's principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act)). Based upon that evaluation, our principal executive officer and principal financial officer concluded that, at September 30, 2024, our disclosure controls and procedures were effective at the reasonable assurance level in ensuring that material information relating to NetScout, including its consolidated subsidiaries, required to be disclosed by NetScout in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, including ensuring that such material information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.
There were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f) occurred during the period covered by this quarterly report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II: OTHER INFORMATION
Item 1.  Legal Proceedings
From time to time, we may be subject to legal proceedings and claims in the ordinary course of business. In the opinion of management, the amount of ultimate expense with respect to any current legal proceedings and claims, if determined adversely, will not have a material adverse effect on the Company's financial condition, results of operations or cash flows. For additional information regarding our legal proceedings, if any, see Note 14 contained in the "Notes to Consolidated Financial Statements" included in Part I of this Quarterly Report on Form 10-Q, which is incorporated herein by reference.
Item 1A.  Risk Factors
In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for our fiscal year ended March 31, 2024. The risks discussed in our Annual Report on Form 10-K could materially affect our business, financial condition and future results. There have been no material changes to those risk factors since we filed our Annual Report on Form 10-K. The risks described in our Annual Report on Form 10-K are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition or operating results.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
BASIS OF PRESENTATION BASIS OF PRESENTATION
The accompanying unaudited interim consolidated financial statements have been prepared by NetScout Systems, Inc. (NetScout or the Company). Certain information and footnote disclosures normally included in financial statements prepared under United States generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, the unaudited interim consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the Company's financial position and stockholders' equity, results of operations and cash flows. The year-end consolidated balance sheet data and statement of stockholders' equity were derived from the Company's audited financial statements, but do not include all disclosures required by GAAP. The results reported in these unaudited interim consolidated financial statements are not necessarily indicative of results that may be expected for the entire year. All significant intercompany accounts and transactions are eliminated in consolidation.
These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company's Annual Report on Form 10-K for the fiscal year ended March 31, 2024 filed with the Securities and Exchange Commission on May 16, 2024.
Global and Macroeconomic Conditions
The Company continues to closely monitor the current global and macroeconomic conditions, including the impacts of the ongoing war in Ukraine and hostilities in the Middle East, global geopolitical tension, stock market volatility, industry-specific capital spending trends, exchange rate fluctuations, inflation, interest rates, and the risk of a recession, including the manner and extent to which they have impacted and could continue to impact its business, customers, employees, supply chain, and distribution network. The full extent of the impacts of these global and macroeconomic trends remain uncertain. It is possible that the measures taken by the governments of countries affected and the resulting economic impacts may materially and adversely affect the Company's future results of operations, cash flows and financial position as well as its customers.
The Company has the responsibility to evaluate whether conditions and/or events raise substantial doubt about its ability to meet its future financial obligations as they become due within one year after the date that the financial statements are issued. The macroeconomic environment remains challenging with constrained customer spending and the Company expects this to persist for the remainder of fiscal year 2025. The Company has taken and continues to take precautionary actions to manage costs and increase productivity across the organization. This includes managing discretionary spending and hiring activities, in addition to a voluntary separation program enacted and substantially completed in the first half of fiscal year 2025. Further, based on covenant levels, the Company had as of September 30, 2024 an incremental $725 million available under the revolving credit facility. On October 4, 2024, the Company amended and extended its Amended Credit facility, which decreased the revolving credit facility from $800 million to $600 million and reduced the incremental amount available under its revolving credit facility to $525 million. See Note 20 "Subsequent Events" for more details.
The Company expects net cash provided by operations combined with cash, cash equivalents, marketable securities and investments and borrowing availability under the revolving credit facility to provide sufficient liquidity to fund current obligations, capital spending, debt service requirements and working capital requirements over at least the next twelve months.

REVENUE

Sep. 30, 2024
Revenue from Contract with Customer [Abstract]  
REVENUE REVENUE
Revenue Recognition Policy
The Company exercises judgment and uses estimates in connection with determining the amounts of product and service revenues to be recognized in each accounting period.
The Company derives revenues primarily from the sale of network management tools and cybersecurity solutions for service provider and enterprise customers, which include hardware, software, and service offerings. The Company's product sales consist of software only offerings and offerings which include hardware appliances with embedded software that are essential to providing customers the intended functionality of the solutions.
The Company accounts for revenue once a legally enforceable contract with a customer has been approved by the parties and the related promises to transfer products or services have been identified. A contract is defined by the Company as an arrangement with commercial substance identifying payment terms, each party's rights and obligations regarding the products or services to be transferred and the amount the Company deems probable of collection. Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. Revenue is recognized when control of the products or services are transferred to the Company's customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for products and services.
Product revenue is typically recognized upon fulfillment, provided a legally enforceable contract exists, control has passed to the customer, and in the case of software products, when the customer has the rights and ability to access the software, and collection of the related receivable is probable. If any significant obligations to the customer remain post-delivery, typically involving obligations relating to installation and acceptance by the customer, revenue recognition is deferred until such obligations have been fulfilled. The Company's service offerings include installation, integration, extended warranty and maintenance services, post-contract customer support, stand-ready software-as-a-service (SAAS) and other professional services including consulting and training. The Company generally provides software and/or hardware support as part of product sales. Revenue related to the initial bundled software and hardware support is recognized ratably over the support period. In addition, customers can elect to purchase extended support agreements for periods after the initial software/hardware warranty expiration. Support services generally include rights to unspecified upgrades (when and if available), telephone and internet-based support, updates, bug fixes and hardware repair and replacement. Consulting services are recognized upon delivery or completion of performance depending on the terms of the underlying contract. Reimbursements of out-of-pocket expenditures incurred in connection with providing consulting services are included in services revenue, with the offsetting expense recorded in cost of service revenue. Training services include on-site and classroom training. Training revenues are recognized upon delivery of the training.
Generally, the Company's contracts are accounted for individually. However, when contracts are closely interrelated and dependent on each other, it may be necessary to account for two or more contracts as one to reflect the substance of the group of contracts.
Bundled arrangements are concurrent customer purchases of a combination of the Company's product and service offerings that may be delivered at various points in time. The Company allocates the transaction price among the performance obligations in an amount that depicts the relative standalone selling prices (SSP) of each obligation. Judgment is required to determine the SSP for each distinct performance obligation. The Company uses a range of amounts to estimate SSP for each of the products and services sold, based primarily on the performance obligation's historical pricing. The Company also considers its overall pricing objectives and practices across different sales channels and geographies, and market conditions. Generally, the Company has established SSP for a majority of its service performance obligations based on historical standalone sales. In certain instances, the Company has established SSP for services based upon an estimate of profitability and the underlying cost to fulfill those services. SSP has primarily been established for product performance obligations as the average or median selling price the performance obligation was recently sold for, whether sold alone or sold as part of a bundle transaction. The Company reviews sales of the product performance obligations on a quarterly basis and updates, when appropriate, its SSP for such performance obligations to ensure that it reflects recent pricing experience. The Company's products are distributed through its direct sales force and indirect distribution channels through alliances with resellers and distributors. Revenue arrangements with resellers and distributors are recognized on a sell-in basis; that is, when control of the product transfers to the reseller or distributor. The Company records consideration given to a customer as a reduction of revenue to the extent they have recorded revenue from the customer. With limited exceptions, the Company's return policy does not allow product returns for a
refund. Returns have been insignificant to date. In addition, the Company has a history of successfully collecting receivables from its resellers and distributors.
During the six months ended September 30, 2024, the Company recognized revenue of $183.5 million related to the Company's deferred revenue balance reported at March 31, 2024.
Performance Obligations
Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. The transaction price is allocated among performance obligations in bundled contracts in an amount that depicts the relative standalone selling prices of each obligation.
For contracts involving distinct hardware and software licenses, the performance obligations are satisfied at a point in time when control is transferred to the customer. For standalone maintenance and post-contract support (PCS) the performance obligation is satisfied ratably over the contract term as a stand-ready obligation. For consulting and training services, the performance obligation may be satisfied over the contract term as a stand-ready obligation, satisfied over a period of time as those services are delivered, satisfied at the completion of the service when control has transferred, or the services have expired unused.
Payments for hardware, software licenses, one-year maintenance, PCS and consulting services, are typically due up front with payment terms of 30 to 90 days. However, the Company does have contracts pursuant to which billings occur ratably over a period of years following the transfer of control for the contracted performance obligations. Payments on multi-year maintenance, PCS and consulting services are typically due in annual installments over the contract term. The Company did not have any material variable consideration such as obligations for returns, refunds or warranties at September 30, 2024.
At September 30, 2024, the Company had total deferred revenue of $379.7 million, which represents the aggregate total contract price allocated to undelivered performance obligations. The Company expects to recognize $263.9 million, or 69%, of this revenue during the next 12 months, and expects to recognize the remaining $115.8 million, or 31%, of this revenue thereafter.
Because of NetScout's revenue recognition policies, there are circumstances for which the Company does not recognize revenue relating to sales transactions that have been billed, but the related account receivable has not been collected. While the receivable represents an enforceable obligation, the Company does not believe its right to payment is unconditional, therefore for balance sheet presentation purposes, the Company has not recognized the deferred revenue or the related account receivable and no amounts appear in the consolidated balance sheets for such transactions because control of the underlying deliverable has not transferred. The aggregate amount of unrecognized accounts receivable and deferred revenue was $7.6 million and $5.9 million at September 30, 2024 and March 31, 2024, respectively.
NetScout expects that the amount of billed and unbilled deferred revenue will change from quarter to quarter for several reasons, including the specific timing, duration and size of large customer support and service agreements, varying billing cycles of such agreements, the specific timing of customer renewals, and foreign currency fluctuations. The Company did not have material significant financing components, or variable consideration or performance obligations satisfied in a prior period recognized during the six months ended September 30, 2024.
Contract Balances
The Company may receive payments from customers based on billing schedules as established by the Company's contracts. Contract assets relate to performance obligations where control has transferred to the customer in advance of scheduled billings. The Company records unbilled accounts receivable representing the right to consideration in exchange for goods or services that have been transferred to a customer conditional on the passage of time. Deferred revenue relates to scenarios where billings with an unconditional right to payment occur before all performance obligations are delivered or payments are received in advance of performance under the contract.
Costs to Obtain Contracts
The Company has determined that the only significant incremental costs incurred to obtain contracts with customers within the scope of Topic 606 are sales commissions paid to its employees. Sales commissions are recorded as an asset and amortized to expense ratably over the remaining performance periods of the related contracts with remaining performance obligations. The Company expenses costs as incurred for sales commissions when the amortization period would have been one year or less.
At September 30, 2024, the consolidated balance sheet included $9.0 million in assets related to sales commissions to be expensed in future periods. A balance of $4.8 million was included in prepaid expenses and other current assets, and a balance
of $4.2 million was included in other assets in the Company's consolidated balance sheet at September 30, 2024. At March 31, 2024, the consolidated balance sheet included $9.3 million in assets related to sales commissions to be expensed in future periods. A balance of $4.8 million was included in prepaid expenses and other current assets, and a balance of $4.5 million was included in other assets in the Company's consolidated balance sheet at March 31, 2024.
During the three and six months ended September 30, 2024 and 2023, respectively, the Company recognized $1.7 million, $1.7 million, $3.4 million and $3.4 million of amortization related to this sales commission asset, which is included in the sales and marketing expense line in the Company's consolidated statements of operations.
Allowance for Credit Losses
The Company continually monitors collections from its customers. The Company evaluates the collectability of its accounts receivable and determines the appropriate allowance for credit losses based on a combination of factors, including but not limited to, analysis of the aging schedules, past due balances, historical collection experience and prevailing economic conditions.
The following table summarizes the activity in the allowance for credit losses (in thousands):

Risks and Uncertainties [Abstract]  
CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS
Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of investments, trade accounts receivable and accounts payable. The Company's cash, cash equivalents, and marketable securities are placed with financial institutions with high credit standings.
At September 30, 2024, the Company had one direct customer over 10% of the accounts receivable balance, while no channel partners accounted for more than 10% of the accounts receivable balance. At March 31, 2024, the Company had no direct customers or channel partners which accounted for more than 10% of the accounts receivable balance.
During the three and six months ended September 30, 2024, and 2023, no direct customers or channel partners accounted for more than 10% of total revenue.
Historically, the Company has not experienced any significant failure of its customers' ability to meet their payment obligations nor does the Company anticipate material non-performance by its customers in the future; accordingly, the Company does not require collateral from its customers. However, if the Company's assumptions are incorrect, there could be an adverse impact on its allowance for doubtful accounts.

SHARE-BASED COMPENSATION SHARE-BASED COMPENSATION
On September 12, 2019, the Company's stockholders approved the 2019 Equity Incentive Plan (2019 Plan), which replaced the Company's 2007 Equity Incentive Plan, as amended (Amended 2007 Plan). The 2019 Plan permits the granting of incentive and nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and other stock awards, collectively referred to as "share-based awards."
On September 10, 2020, the Company's stockholders approved an amendment and restatement of the 2019 Equity Incentive Plan (2019 First Amended Plan) to increase the number of shares reserved for issuance by 4,700,000 shares, establish a one-year minimum vesting requirement for awards granted on or after September 10, 2020, and change the "fungible share counting ratio" used to calculate the increase or reduction in the number of shares available for issuance under the 2019 First Amended Plan.
On August 24, 2022, the Company's stockholders approved an amendment and restatement of the 2019 Equity Incentive Plan (2019 Second Amended Plan) to increase the number of shares reserved for issuance by 7,000,000 shares, and change the "fungible share counting ratio" used to calculate the increase or reduction in the number of shares available for issuance under the 2019 Second Amended Plan.
On September 14, 2023, the Company's stockholders approved an amendment and restatement to the 2019 First Amended Plan (2019 Third Amended Plan) to further increase the number of shares reserved for issuance by 5,900,000 shares and
changed the "fungible share counting ratio" used to calculate the increase or reduction in the number of shares available for issuance under the 2019 Third Amended Plan.
On September 12, 2024, the Company’s stockholders approved an amendment and restatement to the 2019 First Amended Plan (2019 Fourth Amended Plan) to further increase the number of shares reserved for issuance by 3,400,000. At September 12, 2024, the effective date of the 2019 Fourth Amended Plan, there was a total of 7,947,545 shares reserved for issuance under the 2019 Fourth Amended Plan, which consisted of 3,400,000 new shares plus 4,547,545 shares that remained available for grant under the 2019 Third Amended Plan. The Company refers to the 2019 Plan, 2019 First Amended Plan, 2019 Second Amended Plan, 2019 Third Amended Plan and 2019 Fourth Amended Plan collectively as the "Amended 2019 Plan". At September 30, 2024, an aggregate of 8,020,927 shares remained available for grant under the Amended 2019 Plan.
Periodically, the Company grants share-based awards to employees, officers, and directors of the Company and its subsidiaries. Additionally, the Company periodically grants performance-based restricted stock units to certain executive officers that vest based upon the Company's total shareholder return as compared to the Russell 2000 Index over a three-year period. The performance-based restricted stock units are valued using the Monte Carlo Simulation model. The measurement and recognition of compensation expense is based on estimated fair values for all share-based payment awards made to its employees and directors. Share-based award grants are generally measured at fair value on the date of grant based on the number of shares granted and the quoted price of the Company's common stock. Such value is recognized as a cost of revenue or an operating expense over the corresponding vesting period.
The following is a summary of share-based compensation expense including restricted stock units and performance-based restricted stock units granted pursuant to the Company's Amended 2007 Plan and the Amended 2019 Plan, and employee stock purchases made under the Company's 2011 Amended and Restated Employee Stock Purchase Plan (ESPP), based on estimated fair values within the applicable cost and expense lines identified below (in thousands):

Investments
In February 2023, the Company entered into a forward share purchase agreement with Napatech A/S (Napatech), a publicly traded Danish company registered on the Oslo stock exchange, to purchase approximately 6.2 million shares of Napatech's common stock for $7.5 million. In April 2023, the Company settled the forward share purchase contract with Napatech in exchange for approximately 6.2 million shares of Napatech's common stock and recorded a $0.2 million change in the fair value of the derivative instrument in other income (expense), net within the Company's consolidated statement of operations during the six months ended September 30, 2023. As part of the agreement, the Company received the right to designate a representative to be nominated for election to the Napatech Board of Directors, which was approved by Napatech's Nomination Committee in April 2023. The Company accounts for this investment under the equity method and has elected to apply the fair value option to the investment. The Company records the investment at fair value at the end of each period based on the closing price of Napatech's stock and any change in fair value during the period is recorded in other income (expense), net within the Company's consolidated statement of operations. At September 30, 2024 and March 31, 2024, the fair value of the investment in Napatech was $19.8 million and $11.5 million, respectively, and was included in marketable securities and investments in the Company's consolidated balance sheet. During the six months ended September 30, 2024 and 2023, the Company recognized a $7.6 million increase and a $0.1 million increase, respectively, in the fair value of the equity investment
in Napatech in other income (expense), net within the Company's consolidated statement of operations. For the six months ended September 30, 2024, the unrealized gain related to foreign currency translation on the equity investment in Napatech was $0.7 million. For the six months ended September 30, 2023, the unrealized loss related to foreign currency translation on the equity investment in Napatech was immaterial.

FAIR VALUE MEASUREMENTS FAIR VALUE MEASUREMENTS
The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant non-observable inputs. The following tables present the Company's financial assets and liabilities measured on a recurring basis using the fair value hierarchy at September 30, 2024 and March 31, 2024 (in thousands):

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures certain financial assets and liabilities at fair value, including marketable securities and derivative financial instruments.
The Company's Level 1 investments are classified as such because they are valued using quoted market prices or alternative pricing sources with reasonable levels of price transparency.
The Company's Level 2 investments are classified as such because they are valued using observable inputs other than Level 1 quoted prices that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets in markets that are not active.

Goodwill and Intangible Assets Disclosure [Abstract]  
GOODWILL AND INTANGIBLE ASSETS GOODWILL AND INTANGIBLE ASSETS
Goodwill
The Company has one reporting unit. Goodwill is tested for impairment at a reporting unit level at least annually, as of January 31, or on an interim basis if an event occurs or circumstances change (a "Triggering Event") that would, more likely than not, reduce the fair value of the reporting unit below its carrying value.
During fiscal year 2024, the Company recorded $217.3 million in goodwill impairment charges as a result of the sustained decline in the Company's stock price and overall market capitalization. During the first quarter of fiscal year 2025, due to the continued decrease in the Company's stock price and overall market capitalization, along with other qualitative considerations including the continued impact from the conditions in the macroeconomic environment, it was determined a Triggering Event occurred, indicating goodwill may be impaired. Accordingly, the Company conducted a quantitative impairment test of its goodwill at June 30, 2024. The Company estimated the implied fair value of its goodwill using a market approach. As a result of the quantitative impairment test performed during the first quarter of fiscal year 2025, the Company determined goodwill was impaired and recorded a goodwill impairment charge of $427.0 million during the three months ended June 30, 2024. The additional impairment charge recorded in the first quarter of fiscal year 2025 was primarily due to the continued decrease in the Company's stock price from March 31, 2024 to June 30, 2024, an increase in the Company's weighted-average cost of capital, and the refinement to the expected cost synergies that could be realized by a hypothetical buyer as a result of the voluntary separation program (VSP) implemented by the Company in the first quarter of fiscal year 2025, which impacted the company-specific control premium used to determine the fair value of the reporting unit under the market approach. At September 30, 2024, the Company performed a Triggering Event assessment and concluded no event or circumstances occurred that indicated goodwill was further impaired.
Throughout the remainder of the fiscal year 2025, the Company will continue to monitor relevant facts and circumstances, including future changes in its stock price. The Company may be required to record additional goodwill impairment charges. While management cannot predict if or when additional goodwill impairments may occur, future goodwill impairments could have material adverse effects on the Company's results of operations and financial condition.
At September 30, 2024 and March 31, 2024, the carrying amounts of goodwill were $1.1 billion and $1.5 billion, respectively. The change in the carrying amount of goodwill for the six months ended September 30, 2024 was due to the impairment of goodwill, and the impact of foreign currency translation adjustments related to asset balances that are recorded in currencies other than the U.S. Dollar.
The following table summarizes the changes in the carrying amount of goodwill for the six months ended September 30, 2024 as follows (in thousands):
Balance at March 31, 2024

Intangible Assets
The net carrying amounts of intangible assets were $285.6 million and $308.7 million at September 30, 2024 and March 31, 2024, respectively. Intangible assets acquired in a business combination are recorded under the acquisition method of accounting at their estimated fair values at the date of acquisition. The Company amortizes acquired intangible assets over their estimated useful lives.
The Company reviews definite-lived intangible assets for impairment when an event occurs that may indicate potential impairment. In connection with the goodwill impairment analysis performed at June 30, 2024, the Company conducted an impairment test of its definite-lived intangible assets at June 30, 2024. Based on this assessment, the Company concluded that the carrying values of the Company's definite-lived intangible assets were recoverable. At September 30, 2024, the Company performed a Triggering Event assessment and concluded no events or circumstances occurred that indicated intangible assets may be impaired. However, if future events occur or if business conditions deteriorate, the Company may be required to record an impairment loss, and or accelerate the amortization of definite-live intangible assets in the future, which could be material to its results of operations and financial condition.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
NetScout operates internationally and, in the normal course of business, is exposed to fluctuations in foreign currency exchange rates. The exposures result from costs that are denominated in currencies other than the U.S. Dollar, primarily the Euro, British Pound, Canadian Dollar, and Indian Rupee. The Company manages its foreign cash flow risk by hedging forecasted cash flows for operating expenses denominated in foreign currencies for up to twelve months, within specified guidelines through the use of forward contracts. The Company enters into foreign currency exchange contracts to hedge cash flow exposures from costs that are denominated in currencies other than the U.S. Dollar. These hedges are designated as cash flow hedges at inception.
NetScout also periodically enters into forward contracts to manage exchange rate risks associated with certain third-party transactions and for which the Company does not elect hedge accounting treatment as there is no difference in the timing of gain or loss recognition on the hedging instrument and the hedged item.
All of the Company's derivative instruments are utilized for risk management purposes, and the Company does not use derivatives for speculative trading purposes. These contracts will mature over the next twelve months and are expected to impact earnings on or before maturity.

On July 27, 2021, the Company amended and extended its existing credit facility (as amended, the Second Amended and Restated Credit Agreement) with a syndicate of lenders by and among: the Company; JPMorgan Chase Bank, N.A. (JPMorgan), as administrative agent and collateral agent; JPMorgan, Wells Fargo Securities, LLC, BofA Securities Inc., RBC Capital Markets, PNC Capital Markets LLC and Mizuho Bank, Ltd., as joint lead arrangers and joint bookrunners; Santander Bank, N.A., U.S. Bank National Association, Fifth Third Bank National Association, Silicon Valley Bank and TD Bank, N.A., as co-documentation agents; and the lenders party thereto.
The Second Amended and Restated Credit Agreement provides for a five-year, $800.0 million senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million. The Company may elect to use the credit facility for general corporate purposes (including to finance the repurchase of shares of the Company's common stock). The commitments under the Second Amended and Restated Credit Agreement will expire on July 27, 2026, and any outstanding loans will be due on that date. During the six months ended September 30, 2024, the Company repaid $25.0 million of borrowings under the Second Amended and Restated Credit Agreement. At September 30, 2024, $75.0 million was outstanding under the Second Amended and Restated Credit Agreement.
On February 22, 2023, the Company entered into a First Amendment Agreement (First Amendment) of its Second Amended and Restated Credit Agreement with its syndicate of lenders. The Company entered into the First Amendment in order to remove and replace the LIBOR-based interest rate benchmark provisions for U.S. dollar-denominated loans with interest rate benchmark provisions for U.S. dollar-denominated loans based on a term secured overnight financing rate (SOFR).
The First Amendment provides that U.S. dollar-denominated advances under the Second Amended and Restated Credit Agreement will bear interest at a term SOFR rate plus a credit spread adjustment of 0.10% or an Alternate Base Rate (defined in a customary manner), at the option of the Company, plus a margin that ranges from 1.00% per annum for Alternate Base Rate loans and 2.00% per annum for term SOFR loans if the Company's consolidated gross leverage ratio is greater than 3.50 to 1.00, down to 0% per annum for Alternate Base Rate loans and 1.00% per annum for term SOFR loans if the Company's consolidated gross leverage ratio is equal to or less than 1.50 to 1.00. For the period from the delivery of the Company's financial statements for the quarter ended June 30, 2024, until the Company has delivered financial statements for the quarter ended September 30, 2024, the applicable margin will be 1.00% per annum for Term Benchmark Revolving loans and 0% per annum for Alternate Base Rate loans, and thereafter the applicable margin will vary depending on the Company's consolidated gross leverage ratio, ranging from 1.00% per annum for Alternate Base Rate loans and 2.00% per annum for Term Benchmark Revolving loans if the Company's consolidated gross leverage ratio is greater than 3.50 to 1.00, down to 0% per annum for Alternate Base Rate loans and 1.00% per annum for Term Benchmark Revolving loans if the Company's consolidated gross leverage ratio is equal to or less than 1.50 to 1.00.
The Company's consolidated gross leverage ratio is the ratio of its consolidated total debt compared to its consolidated EBITDA as defined in the Second Amended and Restated Credit Agreement (adjusted consolidated EBITDA). Adjusted consolidated EBITDA includes certain adjustments, including, without limitation, adjustments relating to extraordinary, unusual or non-recurring charges, certain restructuring charges, non-cash charges, certain transaction costs and expenses and certain pro forma adjustments in connection with material acquisitions and dispositions, all as set forth in detail in the Second Amended and Restated Credit Agreement.
Commitment fees will accrue on the daily unused amount of the credit facility. For the period from the delivery of the Company's financial statements for the quarter ended June 30, 2024, until the Company has delivered financial statements for the quarter ended September 30, 2024, the commitment fee will be 0.15% per annum, and thereafter the commitment fee will vary depending on the Company's consolidated gross leverage ratio, ranging from 0.30% per annum if the Company's consolidated gross leverage ratio is greater than 2.75 to 1.00, down to 0.15% per annum if the Company's consolidated gross leverage ratio is equal to or less than 1.50 to 1.00.
Letter of credit participation fees are payable to each lender providing the letter of credit sub-facility on the amount of such lender's letter of credit exposure, during the period from the closing date of the Second Amended and Restated Credit Agreement to, but excluding, the date which is the later of (i) the date on which such lender's commitment terminates or (ii) the date on which such lender ceases to have any letter of credit exposure, at a rate per annum equal to the applicable margin for term SOFR loans assuming such loans were outstanding during the period. Additionally, the Company will pay a fronting fee to each issuing bank in amounts to be agreed to between the Company and the applicable issuing bank.
Interest on Alternate Base Rate loans is payable at the end of each calendar quarter. Interest on term SOFR loans is payable at the end of each interest rate period or at the end of each three-month interval within an interest rate period if the
period is longer than three months. The Company may also prepay loans under the Second Amended and Restated Credit Agreement at any time, without penalty, subject to certain notice requirements.
The loans and other obligations under the credit facility are (a) guaranteed by each of the Company's wholly-owned material domestic restricted subsidiaries, subject to certain exceptions, and (b) are secured by substantially all of the assets of the Company and the subsidiary guarantors, including a pledge of all the capital stock of material subsidiaries held directly by the Company and the subsidiary guarantors (which pledge, in the case of any foreign subsidiary, is limited to 65% of the voting stock), subject to certain customary exceptions and limitations. The Second Amended and Restated Credit Agreement generally prohibits any other liens on the assets of the Company and its restricted subsidiaries, subject to certain exceptions as described in the Second Amended and Restated Credit Agreement.
The Second Amended and Restated Credit Agreement contains certain covenants applicable to the Company and its restricted subsidiaries, including, without limitation, limitations on additional indebtedness, liens, various fundamental changes, dividends and distributions, investments (including acquisitions), transactions with affiliates, asset sales, including sale-leaseback transactions, speculative hedge agreements, payment of junior financing, changes in business and other limitations customary in senior secured credit facilities. The Second Amended and Restated Credit Agreement requires the Company to maintain a certain consolidated net leverage ratio and removes the previous requirement under the Company's previous amended credit agreement that the Company maintain a minimum consolidated interest coverage ratio. The Company's consolidated net leverage ratio is the ratio of its Consolidated Total Debt minus the lesser of unrestricted cash and 125% of adjusted consolidated EBITDA compared to its adjusted consolidated EBITDA. The Company's maximum consolidated net leverage ratio is 4.00 to 1.00. These covenants and limitations are more fully described in the Second Amended and Restated Credit Agreement. At September 30, 2024, the Company was in compliance with all covenants, including the specified total consolidated net leverage ratio range of 4.00 to 1.00.
The Second Amended and Restated Credit Agreement provides that events of default will exist in certain circumstances, including failure to make payment of principal or interest on the loans when required, failure to perform certain obligations under the Second Amended and Restated Credit Agreement and related documents including a failure to meet the maximum total consolidated net leverage ratio covenant, defaults under certain other indebtedness, certain insolvency events, certain events arising under ERISA, a change of control and certain other events. Upon an event of default, the administrative agent with the consent of, or at the request of, the holders of more than 50% in principal amount of the loans and commitments, may terminate the commitments and accelerate the maturity of the loans and enforce certain other remedies under the Second Amended and Restated Credit Agreement and the other loan documents.
The Company had unamortized capitalized debt issuance costs, net of $2.0 million at September 30, 2024, which are being amortized over the life of the revolving credit facility. The unamortized capitalized debt issuance costs balance of $1.1 million was included as prepaid expenses and other current assets and a balance of $0.9 million was included as other assets in the Company's consolidated balance sheet at September 30, 2024.

RESTRUCTURING CHARGES RESTRUCTURING CHARGES
During the first quarter of fiscal year 2025, the Company implemented a voluntary separation program (VSP) for employees who met certain age and service requirements to reduce overall headcount. As a result of the related workforce reduction, during the three months and six months ended September 30, 2024, the Company recorded restructuring charges totaling $2.4 million and $19.0 million, respectively, related to one-time termination benefits for one hundred thirty-nine employees who voluntarily terminated their employment with the Company during the six months ended September 30, 2024. The Company estimates that approximately $0.6 million in restructuring charges will be recorded in the third quarter of fiscal year 2025 related to one-time termination benefits for three employees who are expected to voluntarily terminate their employment with the Company during the three months ending December 31, 2024. All one-time termination benefits are expected to be paid in full by the end of the fiscal year ending March 31, 2025.

Leases [Abstract]  
LEASES LEASES
The Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets represent the Company's right to use an underlying asset for the duration of the lease term. Lease liabilities represent the Company's contractual obligation to make lease payments over the lease term. The Company's policy is to combine lease and non-lease components and to not recognize ROU assets and lease liabilities for short-term leases. Leases with an initial term of twelve months or less are classified as short-term leases. ROU assets are recorded and recognized at commencement for the lease liability amount, plus initial direct costs incurred less lease incentives received. Lease liabilities are recorded at the present value of future lease payments over the lease term at commencement. The discount rate used is generally the Company's estimated incremental borrowing rate unless the lessor's implicit rate is readily determinable. Incremental borrowing rates are calculated periodically to estimate the rate the Company would pay to borrow the funds necessary to obtain an asset of similar value over a similar term. Lease expenses relating to operating leases are recognized on a straight-line basis over the lease term.
The Company has operating leases for administrative, research and development, sales and marketing and manufacturing facilities and equipment under various non-cancelable lease agreements. The Company's leases have remaining lease terms ranging from 1 year to 7 years. The Company's lease terms may include options to extend or terminate the lease where it is reasonably certain that the Company will exercise those options. The Company considers several economic factors when making this determination, including but not limited to, the significance of leasehold improvements incurred in the office space, the difficulty in replacing the asset, underlying contractual obligations, or specific characteristics unique to a particular lease. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants.
The Company has asset retirement obligations (ARO) to return certain leased facilities to their original condition at the end of the respective lease term. The estimated fair value of these ARO liabilities is recognized in the period in which the liability is generated and a corresponding increase to the carrying value of the related asset is recorded and depreciated over the useful life of the asset. The Company's estimates of its ultimate AROs could change because of changes in regulations, the extent of environmental remediations required, the means of reclamation, cost estimates, exit or disposal activities or time period estimates. ARO liabilities totaled $2.3 million and $2.3 million at September 30, 2024 and March 31, 2024, respectively. There was a balance of $0.1 million included in accrued other and a balance of $2.2 million included in other long-term liabilities in the consolidated balance sheets at September 30, 2024, and a balance of $0.1 million included in accrued other and a balance of $2.2 million included in other long-term liabilities in the consolidated balance sheets at March 31, 2024. Accretion expense related to these liabilities was not material for any periods presented.
Most of the Company's lease agreements contain variable payments, primarily for common area maintenance (CAM), which are expensed as incurred and not included in the measurement of the ROU assets and lease liabilities.
The components of operating lease cost for the three and six months ended September 30, 2024 and 2023, respectively, were as follows (in thousands):

Commitments and Contingencies Disclosure [Abstract]  
COMMITMENTS AND CONTINGENCIES COMMITMENTS AND CONTINGENCIES
As previously disclosed, in March 2016, Packet Intelligence LLC (Packet Intelligence or Plaintiff) filed a Complaint against NetScout and two subsidiary entities in the United States District Court for the Eastern District of Texas asserting infringement of five United States patents. Plaintiff's Complaint alleged that legacy Tektronix GeoProbe products, including the G10 and GeoBlade products, infringed these patents. NetScout filed an Answer denying Plaintiff's allegations and asserting that Plaintiff's patents were, among other things, invalid, not infringed, and unenforceable due to inequitable conduct. In October 2017, a jury rendered a verdict finding in favor of the Plaintiff and that Plaintiff was entitled to $3.5 million for pre-suit damages and $2.3 million for post-suit damages. In September 2018, the Court entered judgment and "enhanced" the jury verdict in the amount of $2.8 million as a result of a jury finding. The judgment also awarded pre- and post-judgment interest, and a running royalty on the G10 and GeoBlade products until the expiration of the patents at issue, the last date being June 2022. Following the entry of final judgment, NetScout appealed, and in July 2020, the Court of Appeals for the Federal Circuit (Federal Circuit) issued a decision vacating the $3.5 million pre-suit damages award, affirming the $2.3 million post-suit damages award, vacating the $2.8 million enhancement award, and remanding to the district court to determine what, if any, enhancement should be awarded. In March 2021, NetScout filed a petition for a writ of certiorari to the United States Supreme Court, which was denied, challenging, among other issues, the basis for enhanced damages and the patentability of the claimed technology. On September 8 and 9, 2021, in proceedings initiated by third parties that did not involve NetScout, the Patent Trial and Appeal Board (PTAB) invalidated all the patent claims that were also asserted against NetScout in this case. After the PTAB decisions were issued, NetScout moved, among other things, to dismiss the case and enter judgment in its favor on the grounds that the PTAB decisions invalidating the asserted claims precluded Plaintiff from continuing to assert its patent infringement causes of action and from seeking damages from NetScout. The District Court denied NetScout’s motion with respect to its request to dismiss the case and enter judgment in its favor. The District Court entered an amended final judgment awarding Plaintiff $2.3 million in post-suit damages, $1.1 million in enhanced damages, pre- and post-judgment interest, and a running royalty on the G10 and GeoBlade products until the expiration of the patents at issue, the last expiration date being June 2022. On July 20, 2022, NetScout filed a notice of appeal to the Federal Circuit from, among other things, the amended final judgment. On May 2, 2024, in a separate action the Federal Circuit affirmed the PTAB decisions, which as a result found that all of the patent claims asserted by Packet Intelligence against NetScout were invalid. Also on May 2, 2024, the Federal Circuit ruled in NetScout's favor in its appeal, vacating the District Court's final judgment and remanding the case to the District Court to dismiss the case against NetScout as moot. As a result, during the year ended March 31, 2024, NetScout concluded that the risk of loss associated with damages that may result from this case was remote and recorded a $4.6 million reduction in contingent liabilities and legal fees. On June 26, 2024, the District Court issued its Order dismissing the case against NetScout.

PENSION BENEFIT PLANS PENSION BENEFIT PLANS
Certain of the Company's non-U.S. employees participate in noncontributory defined benefit pension plans. None of the Company's employees in the U.S. participate in any noncontributory defined benefit pension plans. In general, these plans are funded based on considerations relating to legal requirements, underlying asset returns, the plan's funded status, the anticipated deductibility of the contribution, local practices, market conditions, interest rates and other factors.
The following sets forth the components of the Company's net periodic pension cost of the noncontributory defined benefit pension plans recorded in operating expenses in the consolidated statements of operations for the three and six months ended September 30, 2024 and 2023, respectively, (in thousands):

During the six months ended September 30, 2024, the Company made contributions of $0.3 million to its defined benefit pension plans. During the fiscal year ending March 31, 2025, the Company's cash contribution requirements for its defined benefit pension plans are expected to be less than $1.0 million. As a majority of the participants within the Company's plans are all active employees, the benefit payments are not expected to be material in the foreseeable future.

On October 24, 2017, the Company's Board of Directors approved a share repurchase program that enabled the Company to repurchase up to twenty-five million shares of its common stock (2017 Share Repurchase Program). Through March 31, 2024, the Company repurchased all of the authorized 25,000,000 shares for $694.1 million in the open market under the 2017 Share Repurchase Program. The Company repurchased 1,117,777 shares for $31.2 million during the six months ended September 30, 2023 under the 2017 Share Repurchase Program.
On May 3, 2022, the Company's Board of Directors approved an additional share repurchase program that enables the Company to repurchase up to twenty-five million shares of its common stock (2022 Share Repurchase Program). The 2022 Share Repurchase Program became effective in the third quarter of fiscal year 2024 when the 2017 Share Repurchase Program was completed. The Company is not obligated to acquire any specific amount of common stock within any particular timeframe as a result of the 2022 Share Repurchase Program. Through September 30, 2024, the Company repurchased 1,976,721 shares for $41.6 million under the 2022 Share Repurchase Program. The Company repurchased 1,362,205 shares for $25.3 million under this share repurchase program during the six months ended September 30, 2024. At September 30, 2024, 23,023,279 shares of common stock remained available to be purchased under the current program.
In connection with the delivery of shares of the Company's common stock upon vesting of restricted stock units, the Company withheld 681,963 shares and 624,941 shares at a cost of $13.5 million and $18.7 million, respectively, related to minimum statutory tax withholding requirements on these restricted stock units during the six months ended September 30, 2024 and 2023, respectively. These withholding transactions do not fall under the share repurchase programs described above, and therefore do not reduce the number of shares that are available for repurchase under those programs.

Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic earnings per share. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding plus the dilutive effect, if any, of outstanding stock options, restricted shares and restricted stock units using the treasury stock method. The calculation of the dilutive effect of outstanding equity awards under the treasury stock method includes consideration of proceeds from the assumed exercise of stock options and unrecognized compensation expense as additional proceeds. As the Company incurred a net loss during the six months ended September 30, 2024, all outstanding restricted stock units and performance-based restricted stock units have an anti-dilutive effect and are therefore excluded from the computation of diluted weighted average shares outstanding.

Generally, the Company's effective tax rate differs from the U.S. federal statutory income tax rate primarily due to foreign withholding taxes and U.S. taxation on foreign earnings, which are partially offset by research and development tax credits and the foreign derived intangible income deduction.
The Company's effective tax rates were 26.8% and 21.9% for the three months ended September 30, 2024 and 2023, respectively. The effective tax rate for the three months ended September 30, 2024 differed from the effective tax rate for the three months ended September 30, 2023 primarily related to an increase in the forecasted benefit of the foreign derived intangible deduction, offset by an increase in foreign withholding taxes.
The Company's effective tax rates were 1.6% and 22.0% for the six months ended September 30, 2024 and 2023, respectively. The effective tax rate for the six months ended September 30, 2024 differed from the effective tax rate for the six months ended September 30, 2023 primarily related to an increase in the forecasted benefit of the foreign derived intangible income deduction offset by an increase in foreign withholding taxes and goodwill impairment incurred during the six months ended September 30, 2024, which was not deductible for tax purposes.

Revenue Recognition Policy
Revenue Recognition Policy
The Company exercises judgment and uses estimates in connection with determining the amounts of product and service revenues to be recognized in each accounting period.
The Company derives revenues primarily from the sale of network management tools and cybersecurity solutions for service provider and enterprise customers, which include hardware, software, and service offerings. The Company's product sales consist of software only offerings and offerings which include hardware appliances with embedded software that are essential to providing customers the intended functionality of the solutions.
The Company accounts for revenue once a legally enforceable contract with a customer has been approved by the parties and the related promises to transfer products or services have been identified. A contract is defined by the Company as an arrangement with commercial substance identifying payment terms, each party's rights and obligations regarding the products or services to be transferred and the amount the Company deems probable of collection. Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. Revenue is recognized when control of the products or services are transferred to the Company's customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for products and services.
Product revenue is typically recognized upon fulfillment, provided a legally enforceable contract exists, control has passed to the customer, and in the case of software products, when the customer has the rights and ability to access the software, and collection of the related receivable is probable. If any significant obligations to the customer remain post-delivery, typically involving obligations relating to installation and acceptance by the customer, revenue recognition is deferred until such obligations have been fulfilled. The Company's service offerings include installation, integration, extended warranty and maintenance services, post-contract customer support, stand-ready software-as-a-service (SAAS) and other professional services including consulting and training. The Company generally provides software and/or hardware support as part of product sales. Revenue related to the initial bundled software and hardware support is recognized ratably over the support period. In addition, customers can elect to purchase extended support agreements for periods after the initial software/hardware warranty expiration. Support services generally include rights to unspecified upgrades (when and if available), telephone and internet-based support, updates, bug fixes and hardware repair and replacement. Consulting services are recognized upon delivery or completion of performance depending on the terms of the underlying contract. Reimbursements of out-of-pocket expenditures incurred in connection with providing consulting services are included in services revenue, with the offsetting expense recorded in cost of service revenue. Training services include on-site and classroom training. Training revenues are recognized upon delivery of the training.
Generally, the Company's contracts are accounted for individually. However, when contracts are closely interrelated and dependent on each other, it may be necessary to account for two or more contracts as one to reflect the substance of the group of contracts.
Bundled arrangements are concurrent customer purchases of a combination of the Company's product and service offerings that may be delivered at various points in time. The Company allocates the transaction price among the performance obligations in an amount that depicts the relative standalone selling prices (SSP) of each obligation. Judgment is required to determine the SSP for each distinct performance obligation. The Company uses a range of amounts to estimate SSP for each of the products and services sold, based primarily on the performance obligation's historical pricing. The Company also considers its overall pricing objectives and practices across different sales channels and geographies, and market conditions. Generally, the Company has established SSP for a majority of its service performance obligations based on historical standalone sales. In certain instances, the Company has established SSP for services based upon an estimate of profitability and the underlying cost to fulfill those services. SSP has primarily been established for product performance obligations as the average or median selling price the performance obligation was recently sold for, whether sold alone or sold as part of a bundle transaction. The Company reviews sales of the product performance obligations on a quarterly basis and updates, when appropriate, its SSP for such performance obligations to ensure that it reflects recent pricing experience. The Company's products are distributed through its direct sales force and indirect distribution channels through alliances with resellers and distributors. Revenue arrangements with resellers and distributors are recognized on a sell-in basis; that is, when control of the product transfers to the reseller or distributor. The Company records consideration given to a customer as a reduction of revenue to the extent they have recorded revenue from the customer. With limited exceptions, the Company's return policy does not allow product returns for a
refund. Returns have been insignificant to date. In addition, the Company has a history of successfully collecting receivables from its resellers and distributors.
