**Basis of Presentation**

The year-end consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). In the opinion of management, the unaudited consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, necessary for their fair statement in conformity with accounting principles generally accepted in the United States of America. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC"). The information included in this Form 10-Q should be read in conjunction with Management's Discussion and Analysis of Financial Condition and Results of Operations and financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2025.

There have been no changes to the Company's significant accounting policies as of and for the three months ended December 31, 2025.

**New Accounting Pronouncements**

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). This ASU requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of this standard on its disclosures in the consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses ("ASU 2024-03"). This ASU requires new financial statement disclosures disaggregating prescribed expense categories within relevant income statement expense captions. In addition, in January 2025, the FASB issued ASU No. 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, which clarifies the effective date of ASU 2024-03. ASU 2024-03 will be effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its disclosures in the consolidated financial statements.

In September 2025, the FASB issued ASU No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software ("ASU 2025-06"). This ASU simplifies the capitalization guidance by removing all references to software development project stages. The revised guidance is neutral to different software development methods. The amendments in this ASU are effective for annual and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of this standard on the consolidated financial statements.

**2. Revenue from Contracts with Customers**

*Capitalized Contract Acquisition Costs*

The table below shows significant movements in capitalized contract acquisition costs (current and noncurrent) for the three months ended December 31, 2025 and 2024 (in thousands):

---

| | | |
|:---|:---|:---|
| | **Three Months Ended<br>December 31,** | **Three Months Ended<br>December 31,** |
| | **2025** | **2024** |
| **Balance, beginning of period** | $76552 | $66258 |
| Additional capitalized contract acquisition costs | 12384 | 13223 |
| Amortization of capitalized contract acquisition costs | (10311) | (9134) |
| **Balance, end of period** | $78625 | $70347 |

---

Amortization of capitalized contract acquisition costs was $10.3 million and $9.1 million for the three months ended December 31, 2025 and 2024, respectively, and is recorded in sales and marketing expense in the accompanying consolidated income statements. There was no impairment of any capitalized contract acquisition costs during any period presented.

*Contract Balances*

Timing may differ between the satisfaction of performance obligations and the invoicing and collection of amounts related to the Company's contracts with customers. Liabilities are recorded for amounts that are collected in advance of the satisfaction of performance obligations, or for contracts with customers that contain the Company's unconditional rights to consideration, for which the customer has not been billed. These liabilities are classified as current and non-current deferred revenue.

The table below shows significant movements in the deferred revenue balances (current and noncurrent) for the three months ended December 31, 2025 and 2024 (in thousands):

---

| | | |
|:---|:---|:---|
| | **Three Months Ended<br>December 31,** | **Three Months Ended<br>December 31,** |
| | **2025** | **2024** |
| **Balance, beginning of period** | $1999237 | $1797959 |
| Amounts added but not recognized as revenues | 493789 | 556919 |
| Revenues recognized related to the opening balance of deferred revenue | (431365) | (408618) |
| **Balance, end of period** | $2061661 | $1946260 |

---

*Remaining Performance Obligations*

Remaining performance obligations represent the amount of the transaction price under contracts with customers that are attributable to performance obligations that are unsatisfied or partially satisfied at the reporting date. The composition of unsatisfied performance obligations consists mainly of deferred service revenue, and to a lesser extent, deferred product revenue, for which the Company has an obligation to perform, and has not yet recognized as revenue in the consolidated financial statements. As of December 31, 2025, the total non-cancelable remaining performance obligations under the Company's contracts with customers was $2.1 billion and the Company expects to recognize revenues on 60.8% of these remaining performance obligations over the next 12 months, 23.9% in year two, and the remaining balance thereafter.

See Note 12, Segment Information, for disaggregated revenue by significant customer and geographic region, as well as disaggregated product revenue by systems and software.

**3. Fair Value Measurements**

***Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis***

The Company's financial assets measured at fair value on a recurring basis at December 31, 2025 and September 30, 2025, were as follows (in thousands):

---

| | | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|:---|
| | | | **Gross Unrealized** | **Gross Unrealized** | | **Classification on Balance Sheet** | **Classification on Balance Sheet** | **Classification on Balance Sheet** |

| *Changes in fair value recorded in other net income (expense):* |  |  |  |  |  |  |  |  |
| Equity investments | \* |  |  |  | $17965 | $— | $— | $17965 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total equity investments |  |  |  |  | 17965 |  |  | 17965 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total |  |  |  |  | $326916 | $308951 | $— | $17965 |

---

\* Equity investments presented in the table above include investments without readily determinable fair values that are measured at fair value using net asset value ("NAV") as a practical expedient, or are measured at cost with adjustments for observable changes in price or impairments. The equity investments are not classified within the fair value hierarchy.

| | | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|:---|

---

\* Equity investments presented in the table above include investments without readily determinable fair values that are measured at fair value using NAV as a practical expedient, or are measured at cost with adjustments for observable changes in price or impairments. The equity investments are not classified within the fair value hierarchy.

The Company uses the fair value hierarchy for financial assets and liabilities. The carrying amounts of other current financial assets and other current financial liabilities approximate fair value due to their short-term nature.

Interest income from cash, cash equivalents, and investments was $8.9 million and $10.3 million for the three months ended December 31, 2025 and 2024, respectively. Interest income is included in other income (expense), net on the Company's consolidated income statements. There were no unrealized losses on investments held for a period greater than 12 months at December 31, 2025 and September 30, 2025.

The Company determined that as of December 31, 2025, there were no credit losses on any investments within its portfolio.

**<u>[Table of](#i5e0fdb32b6db4909a868006660ec385c_7)[Contents](#i5e0fdb32b6db4909a868006660ec385c_7)</u>**

***Assets Measured and Recorded at Fair Value on a Non-Recurring Basis***

The Company's non-financial long-lived assets, which include goodwill and other intangible assets, are not required to be carried at fair value on a recurring basis. These non-financial assets are measured at fair value on a non-recurring basis when there is an indicator of impairment, and they are recorded at fair value only when impairment is recognized. The Company reviews goodwill for impairment annually, during the second quarter of each fiscal year, or as circumstances indicate the possibility of impairment. The Company monitors the carrying value of tangible and intangible long-lived assets for impairment whenever events or changes in circumstances indicate its carrying amount may not be recoverable.

The Company did not recognize any impairment charges related to non-financial long-lived assets for the three months ended December 31, 2025 and 2024.

**4. Business Combinations**

***Fiscal Year 2025 Acquisition of CalypsoAI Corp***

On September 26, 2025, the Company closed on a transaction for the acquisition of CalypsoAI Corp. ("CalypsoAI"), a provider in enterprise AI security for $145.2 million in cash, with CalypsoAI immediately becoming a wholly-owned subsidiary of F5 upon the closing of the transaction. The addition of CalypsoAI's platform brings real-time threat defense, red teaming at scale, and data security to enterprises racing to deploy generative and agentic AI. These capabilities will be integrated into the F5 ADSP to create an enhanced solution for securing AI inference.

As a result of the acquisition, the Company acquired all the assets and assumed all the liabilities of CalypsoAI. The goodwill related to the CalypsoAI acquisition is comprised primarily of expected synergies from combining operations and the acquired intangible assets that do not qualify for separate recognition. Goodwill related to the CalypsoAI acquisition was not deductible for tax purposes. Transaction costs associated with the acquisition were not material.

The allocated purchase consideration to assets acquired and liabilities assumed based on preliminary estimated fair values is presented in the following table (in thousands):

---

| | |
|:---|:---|
| Other net tangible assets acquired, at fair value | $14151 |
| Identifiable intangible assets, developed technology | 16900 |
| Goodwill | 114156 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total net assets acquired | $145207 |

---

The initial allocation of the purchase price was based on preliminary valuations and assumptions and is subject to change within the measurement period. The Company expects to finalize the allocation of the purchase price as soon as practicable and no later than one year from the acquisition date.

The developed technology intangible assets are amortized on a straight-line basis over the weighted average estimated useful life of 4.21 years and included in cost of net product revenues. The estimated useful lives for the acquired intangible assets were based on the expected future cash flows associated with the respective asset.

The pro forma financial information, as well as the revenue and earnings generated by CalypsoAI, were not material to the Company's operations for the periods presented.

***Other Fiscal Year 2025 Acquisitions***

During the second, third and fourth quarters of fiscal 2025, the Company completed three additional acquisitions. The acquired assets and assumed liabilities of the acquisitions were not material and the Company recorded $17.4 million of goodwill as a result of the acquisitions. The acquisitions did not have a material impact to the Company's operating results.

**6. Debt Facilities**

***Revolving Credit Agreement***

On January 31, 2020, the Company entered into a Revolving Credit Agreement (the "Revolving Credit Agreement") that provides for a senior unsecured revolving credit facility in an aggregate principal amount of $350.0 million (the "Revolving Credit Facility"). The Company has the option to increase commitments under the Revolving Credit Facility from time to time, subject to certain conditions, by up to $150.0 million. Historically, borrowings under the Revolving Credit Facility bore interest at a rate equal to, at the Company's option, (a) LIBOR, adjusted for customary statutory reserves, plus an applicable margin of 1.125% to 1.75% depending on the Company's leverage ratio, or (b) an alternate base rate determined in accordance with the Revolving Credit Agreement, plus an applicable margin of 0.125% to 0.750% depending on the Company's leverage ratio. On May 26, 2023, the Company amended the Revolving Credit Agreement as a result of the cessation of the LIBOR borrowing reference rate. The amendment modified and directly replaced the LIBOR borrowing reference rate within the Revolving Credit Agreement to the Secured Overnight Financing Rate ("SOFR"). After the amendment, borrowings under the Revolving Credit Facility bear interest at a rate equal to, at the Company's option, (a) SOFR plus 0.10%, plus an applicable margin of 1.125% to 1.75% depending on the Company's leverage ratio, or (b) an alternate base rate determined in accordance with the Revolving Credit Agreement, plus an applicable margin of 0.125% to 0.750% depending on the Company's leverage ratio. The Revolving Credit Agreement also requires payment of a commitment fee calculated at a rate per annum of 0.125% to 0.300% depending on the Company's leverage ratio on the undrawn portion of the Revolving Credit Facility. Commitment fees incurred during the three months ended December 31, 2024 were not material.

On January 31, 2025, the Company's Revolving Credit Facility, with an aggregate principal amount of $350.0 million, expired. At the time of expiration, there were no outstanding borrowings under the Revolving Credit Facility.

**7. Leases**

The lease commenced in April 2019 and expires in 2033 with an option for renewal. The Company also leases additional office and lab space for product development and sales and support personnel in the United States and internationally. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants.

The components of the Company's operating lease expenses for the three months ended December 31, 2025 and 2024 were as follows (in thousands):

As of December 31, 2025, the Company had no significant operating leases that were executed but not yet commenced.

**8. Commitments and Contingencies**

**Guarantees and Product Warranties**

In the normal course of business to facilitate sales of its products, the Company indemnifies other parties, including customers, resellers, lessors, and parties to other transactions with the Company, with respect to certain matters. The Company has agreed to hold the other party harmless against losses arising from a breach of representations or covenants, or out of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. The Company has entered into indemnification agreements with its officers and directors and certain other employees, and the Company's bylaws contain similar indemnification obligations to the Company's agents. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement.

The Company offers warranties of one year for its systems product offerings. Additional warranty coverage can be purchased by customers through service maintenance agreements in yearly increments. The Company accrues for warranty costs as part of its cost of sales based on associated material product costs and technical support labor costs.

**Commitments**

In October 2022, the Company entered into an unconditional purchase commitment with one of its suppliers for the delivery of systems components. Under the terms of the agreement, the Company is obligated to purchase $10.0 million of component inventory annually, with a total committed amount of $40.0 million over a four-year term. As of December 31, 2025, the Company had no remaining purchase commitments under the fourth year of the agreement. The Company did not have any non-cancelable long-term purchase commitments outstanding as of December 31, 2025.

The Company leases its facilities under operating leases that expire at various dates through 2041. There have been no material changes in the Company's lease obligations compared to those discussed in Note 7 to its annual consolidated financial statements.

**Legal Proceedings**

<u>Lynwood Investment CY Limited v. F5 Networks et al.</u>

On June 8, 2020, Lynwood Investment CY Limited ("Lynwood") filed a lawsuit in the United States District Court for the Northern District of California ("District Court") against the Company and certain affiliates, along with other defendants. In its complaint, Lynwood claims to be the assignee of all rights and interests of Rambler Internet Holding LLC ("Rambler"), and alleges that the intellectual property in the NGINX software originally released by the co-founder of NGINX in 2004 belongs to Rambler (and therefore Lynwood, by assignment) because the software was created and developed while the co-founder was employed by Rambler. Lynwood asserted 26 causes of action against the various defendants, including copyright infringement, violation of trademark law, tortious interference, conspiracy, and fraud. The complaint sought damages, disgorgement of profits, declarations of copyright and trademark ownership, trademark cancellations, and injunctive relief. Lynwood also initiated several trademark opposition and cancellation proceedings before the Trademark Trial and Appeal Board of the United States Patent and Trademark Office, which have all since been suspended.

In August and October 2020, the Company and the other defendants filed motions to dismiss Lynwood's case. On March 25 and 30, 2021, the District Court granted the Company's and the other defendants' motions to dismiss with leave to amend. Lynwood filed its amended complaint on April 29, 2021, seeking the same relief against the Company and other defendants. On May 27, 2021, the Company and other defendants filed a consolidated motion to dismiss.

The District Court granted the consolidated motion to dismiss without leave to amend on August 16, 2022 and entered final judgment against Lynwood on September 9, 2022. Following the District Court's order granting the consolidated motion to dismiss and final judgment in the Company's favor, the District Court subsequently granted the Company attorneys' fees of over $0.8 million, which Lynwood appealed to the Ninth Circuit Court of Appeals. The dismissal appeal and the fees appeal were heard by the Ninth Circuit Court of Appeals ("Court of Appeals") on December 7, 2023. On November 7, 2024, the Court of Appeals partially affirmed the dismissal by affirming dismissal of the state law claims and remanding a portion of the copyright claim to the District Court. The Court of Appeals also vacated the fees award because of the remand.

On December 2, 2024, the Court of Appeals issued its mandate returning the matter to the District Court for further proceedings on the remaining portion of the copyright claim. The parties are engaged in a first phase of discovery ordered by the Court in a March 7th case management conference that is focused on whether any NGINX Plus code was written by individuals employed by Rambler before the end of 2011. On May 19, 2025, the Company and the other defendants answered Lynwood's second amended complaint filed April 7, 2025, which was limited to the remaining portion of the copyright claim focused on NGINX Plus per the Court's March 7th order. The Company intends to continue vigorously defending the litigation.

<u>Smith v. F5, Inc., et al.</u>

On December 19, 2025, Matthew Smith filed a putative class action complaint against F5, Inc., and certain of its executives in the United States District Court for the Western District of Washington, purportedly on behalf of individuals who purchased or otherwise acquired the Company's common stock between October 28, 2024 and October 27, 2025. The complaint alleges that the Company and certain of its officers made false or misleading statements in violation of Sections 10(b) and 20(a) of the Exchange Act of 1934 regarding the Company's cybersecurity capabilities. The complaint requests monetary damages, including interest, reasonable attorney fees, expert fees and other costs. The action is in its early stages. The Company intends to vigorously defend this claim.

In addition to the above matters, the Company is subject to a variety of legal proceedings, claims, investigations, and litigation arising in the ordinary course of business, including intellectual property litigation. Management believes that the Company has meritorious defenses to the allegations made in its pending cases and intends to vigorously defend these claims and lawsuits; however, the Company is unable to currently determine if an unfavorable outcome is probable or estimate any potential amount or range of possible loss of these or similar matters. There are many uncertainties associated with any

litigation and these actions or other third-party claims against the Company may cause it to incur costly litigation and/or substantial settlement charges that could have a material adverse effect on the Company's business, financial condition, results of operations, and cash flows.

The Company records an accrual for loss contingencies for legal proceedings when it believes that an unfavorable outcome is both (a) probable and (b) the amount or range of any possible loss is reasonably estimable. The Company has not recorded any accrual for loss contingencies associated with such legal proceedings or the investigations discussed above.

**Cyber Incident**

On October 15, 2025, the Company disclosed a security incident in which a threat actor maintained long-term, persistent access to F5 systems, and certain files were exfiltrated, referred to as the "Cyber Incident." In connection with the Cyber Incident, some customers and third parties may assert claims against the Company and/or officers and directors of the Company. The Company has also received a small number of inquiries from governmental authorities. The Company is cooperating and providing information in connection with these inquiries.

The Company may incur significant legal and professional services and other expenses associated with the incident in future periods. These expenses will be recognized as incurred. Certain costs may be recoverable under the Company's insurance policies. Any amounts recoverable under such policies will be reflected in future periods in which recovery is considered probable. The Company incurred $17.5 million of costs in response to the Cyber Incident for the three months ended December 31, 2025.

**9. Income Taxes**

The Company's tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete items in the related period.

The effective tax rate was 19.2% and 20.4% for the three months ended December 31, 2025 and 2024, respectively. The decrease in the effective tax rate for the three months ended December 31, 2025 as compared to the three months ended December 31, 2024 is primarily due to change in unrecognized tax benefits.

At December 31, 2025, the Company had $80.9 million of unrecognized tax benefits that, if recognized, would affect the effective tax rate. It is anticipated that the Company's existing liabilities for unrecognized tax benefits will change within the next twelve months due to audit settlements or the expiration of statutes of limitations. The Company does not expect these changes to be material to the consolidated financial statements. The Company recognizes interest and, if applicable, penalties for any uncertain tax positions as a component of income tax expense.

The Company and its subsidiaries are subject to U.S. federal income tax as well as the income tax of multiple state and foreign jurisdictions. The Company has concluded all U.S. federal income tax matters for fiscal years through September 30, 2018, as well as fiscal years 2020 and 2021. Major jurisdictions where there are wholly owned subsidiaries of F5, Inc. which require income tax filings include the United Kingdom, Singapore, Israel, and India. The earliest periods open for review by local taxing authorities are fiscal years 2024 for the United Kingdom, 2024 for Singapore, 2020 for Israel, and 2019 for India. The Company is currently under audit by the Internal Revenue Service for fiscal year 2019, by various states for fiscal years 2018 through 2022, and by various foreign jurisdictions including India for fiscal years 2019 to 2024, Israel for fiscal years 2020 to 2023, and Saudi Arabia for fiscal years 2015 to 2021.

On July 4, 2025, the One Big Beautiful Bill Act was enacted into law. Applicable changes resulting from this legislation are not material for the current period and have been reflected in the Company's consolidated financial statements.

**10. Shareholders' Equity**

***Common Stock Repurchase***

On October 25, 2024, the Company announced that its Board of Directors authorized an additional $1.0 billion for its common stock share repurchase program. This authorization was incremental to the existing $6.4 billion program, initially approved in October 2010 and expanded in subsequent fiscal years. Acquisitions for the share repurchase programs will be made from time to time in private transactions, accelerated share repurchase programs, or open market purchases as permitted by securities laws and other legal requirements. The programs can be terminated at any time.

| Amount repurchased | $300024 | $125010 |

---

As of December 31, 2025, the Company had $622.4 million remaining authorized to purchase shares under its share repurchase program.

**11. Net Income Per Share**

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of common and dilutive common stock equivalent shares outstanding during the period. The Company's nonvested restricted stock units do not have nonforfeitable rights to dividends or dividend equivalents and are not considered participating securities that should be included in the computation of earnings per share under the two-class method.

The following table sets forth the computation of basic and diluted net income per share (in thousands, except per share data):

---

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Weighted average shares outstanding — diluted | 58164 | 59058 |
| Basic net income per share | $3.12 | $2.85 |
| Diluted net income per share | $3.10 | $2.82 |

---

Anti-dilutive stock-based awards excluded from the calculations of diluted earnings per share were not material for the three months ended December 31, 2025 and 2024.

**12. Segment Information**

Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision-maker, or decision-making group, in deciding how to allocate resources and in assessing performance. Management has determined that the Company is organized as, and operates in, one reportable operating segment.

The Company's Chief Executive Officer, who is the chief operating decision maker ("CODM"), regularly assesses performance and decides how to allocate resources primarily based on consolidated net income reported in the Consolidated Income Statements. The CODM uses consolidated net income to assess performance and make operating decisions by monitoring consolidated net income actual results compared to forecasted results, as well as reviewing historical performance trends. The CODM also manages the Company's operations by reviewing consolidated net revenues by products and services and consolidated expense information consistent with the financial statement line items reported in the Consolidated Income Statements. Significant expenses include cost of net revenues by products and services, sales and marketing expenses, research and development expenses, general and administrative expenses, restructuring charges, and provision for income taxes, all of which are presented in the Consolidated Income Statements. Other segment items primarily include interest income, interest expense, and foreign currency transactions gains and losses, which are presented in other income, net in the Consolidated Income Statements. The measure of segment assets is reported on the Consolidated Balance Sheets as total assets.

*Revenues by Geographic Location and Other Information*

The Company does business in three main geographic regions: the Americas (primarily the United States); Europe, the Middle East, and Africa ("EMEA"); and the Asia Pacific region ("APAC"). The Company's CODM reviews financial information presented on a consolidated basis accompanied by information about net product revenues and revenues by geographic region.

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

The following discussion of our financial condition and results of operations contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934 and Section 27A of the Securities Act of 1933. These statements include, but are not limited to, statements about our plans, objectives, expectations, strategies, intentions or other characterizations of future events or circumstances and are generally identified by the words "expects," "anticipates," "intends," "plans," "believes," "seeks," "estimates," and similar expressions. These forward-looking statements are based on current information and expectations and are subject to a number of risks and uncertainties. Our actual results could differ materially from those expressed or implied by these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in Part II, Item 1A. "Risk Factors" herein and in other documents we file from time to time with the Securities and Exchange Commission. We assume no obligation to revise or update any such forward-looking statements.

**Overview** 

F5 is a global leader in application delivery and security solutions which enables its customers to deploy, operate, secure, optimize, and govern every application and API across on-premises architectures, in the cloud, and at the network edge. Our cloud, software, and hardware solutions enable our customers to deliver fast, available, and secure digital experiences to their customers at scale. Our enterprise-grade application services are available as hardware, software, and SaaS solutions optimized for hybrid, multicloud environments, with modules that can run independently, or as part of an integrated solution on our high-performance appliances. We market and sell our products primarily through multiple indirect sales channels in our Americas; Europe, the Middle East, and Africa ("EMEA"); and Asia Pacific ("APAC") regions. Enterprise customers (Fortune 1000 or Business Week Global 1000 companies) in the technology, financial services, transportation, education, manufacturing, and health care industries, along with government customers, and service providers continue to make up the largest percentage of our customer base.

Our management team monitors and analyzes a number of key performance indicators in order to manage our business and evaluate our financial and operating performance on a consolidated basis. Those indicators include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Revenues.* Our revenue is derived from the sales of both products and services. The majority of our product revenues are derived from sales of our application delivery and security solutions including our F5 BIG-IP software and systems, F5 NGINX software, and our F5 Distributed Cloud Services offerings. Our F5 BIG-IP software solutions are sold both on a subscription and perpetual license basis. We sell F5 NGINX on a subscription basis as deployable software or SaaS. F5 Distributed Cloud Services provides security, multicloud networking, and edge-based computing solutions and are offered on a subscription basis, under a unified SaaS platform and managed service platform. Our services revenue includes annual maintenance contracts, training and consulting services.

We monitor the sales mix of our revenues within each reporting period. We believe customer acceptance rates of our new products, feature enhancements and consumption models are indicators of future trends. We also consider overall revenue concentration by geographic region as an additional indicator of current and future trends.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Cost of revenues and gross margins.* We strive to control our cost of revenues and thereby maintain our gross margins. Significant items impacting cost of revenues are hardware costs paid to our contract manufacturers, personnel costs, including the salaries, stock-based compensation and related benefits of our personnel, technology costs, including third-party cloud hosting and related services, depreciation of cloud infrastructure costs, software licenses expenses, and amortization expense in connection with developed technology from acquisitions. In addition, factors such as sales price, product and services mix, inventory obsolescence, returns, component price increases, warranty costs, and global supply chain constraints could significantly impact our gross margins.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Operating expenses.* Operating expenses are substantially driven by personnel and related overhead expenses. Existing headcount and future hiring plans are the predominant factors in analyzing and forecasting future operating expense trends. Other significant operating expenses that we monitor include costs associated with cyber and enterprise-wide security, marketing and promotions, travel, professional fees, technology costs, including cloud hosting and software licenses expenses, related to the development of new products and provision of services, facilities and depreciation expenses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Liquidity and cash flows.* Our financial condition remains strong with significant cash and investments. The decrease in cash and investments for the first three months of fiscal year 2026 was primarily due to cash used to repurchase outstanding common stock under our stock repurchase program, including excise taxes, of $301.1 million, partially offset by cash provided by operating activities of $159.2 million. Going forward, we believe the primary driver of cash flows will continue to be net income from operations. We will continue to evaluate possible acquisitions of, or investments in businesses, products, or technologies that we believe are strategic, which may require the use of cash.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Balance sheet.* We view cash, short-term and long-term investments, deferred revenue, accounts receivable balances and days sales outstanding as important indicators of our financial health. Deferred revenues continued to increase in the first quarter of fiscal year 2026 primarily due to an increase in initial and renewal maintenance contracts related to strong systems shipments and our existing product installation base, respectively. Our days sales outstanding for the first quarter of fiscal year 2026 was 54. Days sales outstanding is calculated by dividing ending accounts receivable by revenue per day for a given quarter.

**Cyber Incident**

On October 15, 2025, we disclosed a security incident in which a threat actor maintained long-term, persistent access to F5 systems, and exfiltrated certain files, referred to as the "Cyber Incident." For further information about the Cyber Incident, see "Risk Factors" included in Item 1A of Part I and "Management's Discussion and Analysis of Financial Condition and Results of Operations - Cyber Incident" included in Item 7 of Part II of the Annual Report on Form 10-K for the fiscal year ended September 30, 2025.

**Critical Accounting Estimates**

The preparation of our financial condition and results of operations requires us to make judgments and estimates that may have a significant impact upon our financial results. We believe that, of our significant accounting policies, revenue recognition requires estimates and assumptions that require complex, subjective judgments by management, which can materially impact reported results. Actual results may differ from these estimates under different assumptions or conditions.

There were no material changes to our critical accounting policies and estimates compared to the critical accounting policies and estimates described in "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Form 10-K for the fiscal year ended September 30, 2025.

**Recent Accounting Pronouncements**

The anticipated impact of recent accounting pronouncements is discussed in Note 1 to the accompanying Notes to Consolidated Financial Statements of this Quarterly Report on Form 10-Q.

**Impact of Macroeconomic Conditions**

Our overall performance depends in part on worldwide economic and geopolitical conditions and their impacts on customer behavior. Uncertain economic conditions, including inflation, tariffs and other duties, risks related to global supply chain shortages that may impact sourcing of components used within our products, higher interest rates, slower growth, fluctuations in foreign exchange rates, and other changes in economic conditions, may adversely affect our results of operations

and financial performance. For further discussion of the potential impacts of recent macroeconomic events on our business, financial condition, and operating results, see Part I, Item 1A, "Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended September 30, 2025.

*Net Product Revenues.* Net product revenues increased $41.8 million, or 11.3% for the three months ended December 31, 2025, from the comparable period in the prior year. The increase in net product revenues was due to an increase in revenues associated with systems of $58.6 million, partially offset by a decrease in revenues associated with software of $16.9 million.

*Net Service Revenues.* Net service revenues increased $14.2 million, or 3.6% for the three months ended December 31, 2025, from the comparable period in the prior year. The increase in net service revenues was primarily the result of increased initial purchases and renewals of maintenance contracts driven by growth in product revenue.

Total systems revenue increased 36.7% for the three months ended December 31, 2025, from the comparable period in the prior year. The increase in systems revenue was primarily due to increases in customer demand. Total software revenue decreased 8.1% for the three months ended December 31, 2025, from the comparable period in the prior year. The decrease in software revenue was primarily due to decreases in perpetual software sales.

*Other Income, Net.* The change in other income, net for the three months ended December 31, 2025 compared to the same period in the prior year was primarily driven by interest income and expense, investment income, and foreign currency transaction gains and losses.

*Provision for Income Taxes*. We record a valuation allowance to reduce our deferred tax assets to the amount we believe is more likely than not to be realized. In making these determinations we consider historical and projected taxable income, and ongoing prudent and feasible tax planning strategies in assessing the appropriateness of a valuation allowance. Our net deferred tax assets at December 31, 2025 and September 30, 2025 were $454.3 million and $444.5 million, respectively. The net deferred tax assets include valuation allowances of $34.3 million as of December 31, 2025 and September 30, 2025, which are primarily related to certain state and foreign net operating losses and tax credit carryforwards.

Our worldwide effective tax rate may fluctuate based on a number of factors, including variations in projected taxable income in the various geographic locations in which we operate, the impact of stock-based compensation, changes in the valuation of our net deferred tax assets, resolution of potential exposures, tax positions taken on tax returns filed in the various geographic locations in which we operate, and the introduction of new accounting standards or changes in tax laws or interpretations thereof in the various geographic locations in which we operate. We have recorded liabilities to address potential tax exposures related to business and income tax positions we have taken that could be challenged by taxing authorities. The ultimate resolution of these potential exposures may be greater or less than the liabilities recorded, which could result in an adjustment to our future tax expense.

**Liquidity and Capital Resources**

Cash and cash equivalents, short-term investments and long-term investments totaled $1,217.7 million as of December 31, 2025, compared to $1,360.0 million as of September 30, 2025, representing a decrease of $142.3 million. The decrease was primarily due to cash used for the repurchase of common stock and the payment of related excise taxes of $301.1 million during the three months ended December 31, 2025, partially offset by cash provided by operating activities of $159.2 million.

Cash provided by operating activities for the first three months of fiscal year 2026 resulted from net income of $180.1 million combined with changes in operating assets and liabilities, as adjusted for various non-cash items including stock-based compensation, deferred revenue, depreciation, impairment and amortization charges. Cash provided by operating activities for the first quarter of fiscal 2026 decreased from the comparable period in the prior year primarily due to an increase in payments made in excess of cash received from customers.

Cash from operations could be affected by various risks and uncertainties, including, but not limited to, the effects of the risks detailed in Part I, Item 1A, "Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended September 30, 2025. However, we anticipate our current cash, cash equivalents and investment balances and anticipated cash flows generated from operations will be sufficient to meet our liquidity needs.

Cash used in investing activities was $10.6 million for the three months ended December 31, 2025, compared to cash used in investing activities of $10.0 million for the same period in the prior year. Investing activities include purchases, sales and maturities of available-for-sale securities, business acquisitions and capital expenditures. The amount of cash used in

investing activities for the three months ended December 31, 2025 was primarily the result of $9.7 million in capital expenditures related to maintaining our operations worldwide.

Cash used in financing activities was $293.0 million for the three months ended December 31, 2025, compared to cash used in financing activities of $114.7 million for the same period in the prior year. Our financing activities for the three months ended December 31, 2025 primarily consisted of $301.1 million of cash used to repurchase shares of common stock and the payment of related excise taxes. In addition, $14.8 million in cash was used for taxes related to net share settlement of equity awards. Cash used in financing activities was partially offset by cash received from the exercise of employee stock options and stock purchases under our employee stock purchase plan of $22.8 million.

**Obligations and Commitments**

As of December 31, 2025, our principal commitments consisted of obligations outstanding under operating leases and purchase obligations with one of our component suppliers.

We lease our facilities under operating leases that expire at various dates through 2041. There have been no material changes in our principal lease commitments compared to those discussed in Management's Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2025.

In October 2022, we entered into an unconditional purchase commitment with one of our suppliers for the delivery of systems components. Under the terms of the agreement, we are obligated to purchase $10 million of component inventory annually, with a total committed amount of $40 million over a four-year term. As of December 31, 2025, we had no remaining purchase commitments under the fourth year of the agreement. We did not have any non-cancelable long-term purchase commitments outstanding as of December 31, 2025.

We have a contractual obligation to purchase inventory components procured by our primary contract manufacturer in accordance with our annual build forecast. The contractual terms of the obligation contain cancellation provisions, which reduce our liability to purchase inventory components for periods greater than one year. In order to support our build forecast, we will, from time-to-time prepay our primary contract manufacturer for inventory purchases.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk**

*Interest Rate Risk.* Our current cash and cash equivalents consist of money market funds as allowed and specified in our investment policy guidelines. Due to the current nature of our investment portfolio, we do not believe an immediate 10% increase or decrease in interest rates would have a material effect on the fair market value of our portfolio. Therefore, we do not expect our operating results or cash flows to be materially affected by a sudden change in interest rates.

*Inflation Risk.* We are actively monitoring the macroeconomic inflationary environment, including the impact from changes in foreign trade policies, tariffs, and other duties, but we do not believe that inflation has had a material effect on our business, financial condition or results of operations. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, financial condition and results of operations. If the inflationary environment constrains our customers' ability to procure goods and services from us, we may see customers reprioritize these investment decisions. These macroeconomic conditions could harm our business, financial condition and results of operations.

*Foreign Currency Risk.* The majority of our sales, cost of net revenues, and operating expenses are denominated in U.S. dollars ("USD"). While we conduct transactions in foreign currencies and expect to continue to do so, to date we have not, and do not anticipate that related foreign currency transaction gains or losses will be significant at our current level of operations. However, as we operate in and continue to expand our operations internationally, fluctuations in foreign currency exchange rates relative to the USD, could impact our foreign currency-denominated costs and may result in operating margin volatility. To date, such fluctuations have not had a material impact on our financial results.

Management believes there have been no material changes to our quantitative and qualitative disclosures about market risk during the three month period ended December 31, 2025, compared to those discussed in our Annual Report on Form 10-K for the year ended September 30, 2025.

**Item 4. Controls and Procedures**

The Company maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) which are designed to ensure that required information is recorded, processed, summarized and reported within the required timeframe, as specified in the rules set forth by the Securities Exchange Commission. Our disclosure controls and procedures are also designed to ensure that information required to be disclosed is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2025 and, based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of December 31, 2025.
