The preparation of the consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions in the Company’s consolidated financial statements. These estimates are based on information available as of the date of the consolidated financial statements. Such management estimates and assumptions include, but are not limited to the determination of:

The Company operates as a single operating segment and derives revenue primarily from fees earned from subscription-based arrangements for providing customers with software in a cloud-based-infrastructure that the Company provides, and from the sale of on-premises term license agreements.

An operating segment is defined as a component of an entity for which discrete financial information is available and whose results of operations are regularly reviewed by the chief operating decision maker (“CODM”). The Company has identified the CEO, Mike Cannon-Brookes, as the CODM. The CODM manages the Company using consolidated financial information. Further, the Company offers a connected portfolio of apps that are built on a single Atlassian platform and data model. Accordingly, the Company has determined it operates as a single operating and reportable segment.

The CODM uses consolidated net loss to allocate resources, including headcount, and make business investment decisions during the Company’s budgeting process. The CODM also uses consolidated net loss to assess performance by comparing the consolidated results to forecasts. Significant segment expenses are organized by function and are presented on the consolidated statements of operations. Other segment items

The Company’s consolidated financial statements are presented using the U.S. dollar, which is its reporting currency. The functional currency for certain of the Company’s foreign subsidiaries is the U.S. dollar, while others use local currencies. The Company translates the foreign functional currency financial statements to U.S. dollars for those entities that do not have the U.S. dollar as their functional currency using the exchange rates at the balance sheet date for assets and liabilities, the period average exchange rates for revenues and expenses, and the historical exchange rates for equity transactions. The effects of foreign currency translation adjustments are recorded in accumulated other comprehensive income in the Consolidated Statements of Comprehensive Loss. Foreign currency transaction gains and losses are included in other income (expense), net on the Consolidated Statements of Operations.

Revenues are generally recognized upon the transfer of control of promised products or services provided to customers, reflecting the amount of consideration the Company expects to receive for those products or services. The Company enters into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of sales and other similar taxes collected from customers, which are subsequently remitted to governmental authorities.

The timing of revenue recognition may differ from the timing of billing to its customers. The Company receives payments from customers based on a billing schedule as established in its contracts. Contract assets are recognized when performance is completed in advance of billings. Deferred revenue is recorded when billings are in advance of performance under the contract. The Company’s revenue arrangements include standard warranty provisions that the products and services will perform and operate in all material respects with the applicable published specifications, the financial impacts of which have historically been and are expected to continue to be insignificant. The Company’s contracts do not include a significant financing component.

The Company allocates the transaction price for each customer contract to each performance obligation based on the relative SSP for each distinct performance obligation. Judgment is required in determining the SSP for each distinct performance obligation. The Company typically determines an SSP range for its products and services, which is reassessed on a periodic basis or when facts and circumstances change. In most cases, the Company is able to determine SSP based on the observable prices of products or services sold separately. In instances where performance obligations do not have observable standalone sales, the Company utilizes available information that may include market conditions, pricing strategies, the life of the software, and other observable inputs to estimate the price that it would charge if the products and services were sold separately.

Revenue recognized from contracts with customers is disaggregated into categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. The Company reports revenues in two categories: (i) subscription, (ii) other. In addition, revenue is presented by geographic region and deployment option in Note 13, “Revenue.”

Subscription revenues consist primarily of fees earned from subscription-based arrangements for providing customers the right to use the Company’s software in a cloud-based-infrastructure that the Company provides. The Company also sells on-premises term license agreements for its Data Center offerings, which consist of software licensed for a specified period and include support and maintenance services that are bundled with the license for the term of the license period. Subscription revenues are driven primarily by the number and size of active licenses, the type of deployment, and the price of the licenses. For Cloud offerings, subscription revenue is recognized ratably as services are performed, commencing with the date the service is made available to customers. For Data Center offerings, the Company recognizes revenue upfront for the portion that relates to the delivery of the term license, and the revenue related to support is recognized ratably as the services are performed over the term of the arrangement.

In September 2025, the Company announced plans to end-of-life its Data Center offering. As of March 2026, the Company no longer sells term licenses to new customers, and will stop selling term licenses and expansions to existing customers in March 2028. Subject to limited exceptions, the Company plans to end maintenance and support for these on-premises versions of its products in March 2029.

Other revenues primarily include fees received for sales of third-party apps in the Atlassian Marketplace. Advisory services and training services are also included in other revenues. Revenue from the sale of third-party apps via Atlassian Marketplace is recognized on the date of product delivery given that all of the Company’s obligations have been met at that time and on a net basis as the Company functions as the agent in the relationship. Revenue from advisory services is recognized over the time period that the customer has access to the service. Revenue from advisory and training is recognized over time as the services are performed.

Deferred contract acquisition costs are costs incurred to obtain a contract, if such costs are recoverable, and consist primarily of sales commissions and related payroll taxes. Incremental costs of obtaining a contract are earned on new and expansion contracts which are capitalized and amortized over the average period of benefit, which the Company estimates to be four years.

The Company determines the period of benefit for commissions paid for the acquisition of the customer contract by taking into consideration the initial estimated customer life, anticipated renewals, and the technological life of its software. The Company includes the deferred contract costs in prepaid expense and other current assets and other non-current assets on the Consolidated Balance Sheets and the amortization of deferred contract acquisition costs in marketing and sales expense on the Consolidated Statements of Operations.

Cash and cash equivalents consist of highly liquid investments with an original maturity of three months or less at the date of purchase. Cash equivalents also include amounts due from third-party credit card processors as they are both short-term and highly liquid in nature and are typically converted to cash within three days of the sales transaction. Cash and cash equivalents are stated at fair value.

As of June 30, 2026 and 2025, the Company had restricted cash of $9.8 million and $0.9 million, respectively, primarily used for the benefit of employees through a deferred compensation plan and future payments of voluntary disability insurance claims. Restricted cash was not available for use in the Company’s operations and is included in other non-current assets in the Consolidated Balance Sheets.

The Company records trade accounts receivable at the invoice value, and such receivables are non-interest bearing. The Company considers receivables past due based on the contractual payment terms. The Company makes estimates of expected credit and collectability trends based on an assessment of various factors including historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment that may affect the Company’s ability to collect from customers. The allowance for credit losses and write offs were not material for each of the periods ended June 30, 2026, 2025 and 2024.

Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the quality and reliability of the information used to determine fair values. Categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is defined into the following three categories of inputs:

•Level 2 - Observable inputs (other than Level 1 prices) such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities;

•Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or examination.

The Company classifies all marketable debt securities that have original stated maturities of greater than three months as marketable securities on its Consolidated Balance Sheets. The Company determines the appropriate classification of its investments in marketable debt securities at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its marketable debt securities as available-for-sale (“AFS”). After consideration of its risk versus reward objectives, as well as its liquidity requirements, the Company may sell these debt securities prior to their stated maturities. The Company considers all of its marketable securities as funds available for use in current operations, including those with maturity dates beyond one year, and therefore classifies these securities as current assets on the Consolidated Balance Sheets.

The Company evaluates AFS securities with unrealized loss positions for credit loss by assessing whether the decline in fair value below the amortized cost basis has resulted from a credit loss or other factors, whether the Company expects to recover the entire amortized cost basis of the security, its intent to sell and whether it is more likely than not that the Company will be required to sell the securities before the recovery of their amortized cost basis. The Company carries these securities at fair value, and reports the unrealized gains and losses, net of taxes, as a component of accumulated other comprehensive income except for the changes in allowance for expected credit losses, which are recorded in other income (expense), net. Realized gains and losses are determined based on the specific identification method and are reported in other income (expense), net on the Consolidated Statements of Operations.

The Company holds strategic investments in privately held debt and equity securities. Investments in privately held debt securities are classified as AFS securities. Investments in privately held equity securities without readily determinable fair values in which the Company does not own a controlling interest or have significant influence over are measured in accordance with the measurement alternative. In applying the measurement alternative, the carrying value of the investment is measured at cost, less impairment, if any, plus or minus changes resulting from observable price changes from orderly transactions for the identical or a similar investment of the same issuer in the period of occurrence. Changes to the carrying value of these investments are recorded through other income (expense), net on the Consolidated Statements of Operations.

In determining adjustments to the carrying value of its strategic investments in privately held companies, the Company uses the most recent data available to the Company. Valuations of privately held securities are inherently complex and the determination of whether an orderly transaction is for an identical or similar investment requires judgment. In its evaluation, the Company considers factors such as differences in the rights and preferences of the investments and the extent to which those differences would affect the fair values of those investments. The Company’s impairment analysis encompasses an assessment of both qualitative and quantitative factors, including the investee’s financial metrics, market acceptance of the investee’s product or technology, general market conditions, and liquidity considerations.

During fiscal year 2026, the Company held equity securities in publicly-traded entities for which the Company did not have a controlling interest. Investments in publicly traded equity securities were recorded at fair value with changes in the fair value of the investments recorded in other income (expense), net in the Consolidated Statements of Operations. The Company did not hold any publicly traded equity securities as of June 30, 2026.

Privately held equity securities in which the Company does not have a controlling financial interest but does exercise significant influence over the investment are accounted for under the equity method. The Company records a proportionate share of the investment’s earnings or losses, and impairment, if any, as a component of other income (expense), net in the Consolidated Statements of Operations. These investments are included in strategic investments in the Consolidated Balance Sheets.

For entities that meet the definition of a variable interest entity (“VIE”), the Company consolidates those entities when the Company is the primary beneficiary of the entity. The Company is determined to be the primary beneficiary when it possesses both the unilateral power to direct activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The Company continually evaluates whether it qualifies as the primary beneficiary and reconsiders its determination of whether an entity is a VIE upon reconsideration events. As of June 30, 2026, the Company has one investment in an unconsolidated VIE for which it exercises significant influence over their operations and accordingly accounts for it as an equity method investment.

The Company enters into foreign exchange forward contracts with the objective to mitigate certain currency risks associated with cost of revenues and operating expenses denominated in foreign currencies. These foreign exchange forward contracts are designated as cash flow hedges. The Company also enters into foreign exchange forward contracts to hedge a portion of certain foreign currency denominated as monetary assets and liabilities to reduce the risk that such foreign currency will be adversely affected by changes in exchange rates. The Company does not enter into derivative instrument transactions for trading or speculative purposes.

Hedging derivative instruments are recognized as either assets or liabilities and are measured at fair value. For derivative instruments designated as cash flow hedges, the gains (losses) on the derivatives are initially reported as a component of other comprehensive income and are subsequently recognized in earnings when the hedged exposure is recognized in earnings. For derivative instruments that are not designated as hedges, gains (losses) from changes in fair values are primarily recognized in other income (expense), net. The Company enters into master netting agreements with financial institutions to execute its hedging program. The master netting agreements are with select financial institutions to reduce the Company’s credit risk, as well as to reduce its concentration of risk with any single counterparty.

The Company determines if an arrangement is a lease at inception. The Company’s lease agreements generally contain lease and non-lease components. Payments under the Company’s lease arrangements are primarily fixed. Non-lease components primarily include payments for maintenance and utilities. The Company combines fixed payments for non-lease components with lease payments and accounts for them together as a single lease component, which increases the amount of its lease assets and liabilities.

Lease assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the Company’s incremental borrowing rate, because the interest rate implicit in the Company’s leases is not readily determinable. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. The Company’s lease terms include periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company generally uses the base, non-cancelable, lease term when determining the lease assets and liabilities. The Company reassesses the lease term if and when a significant event or change in circumstances occurs. Lease assets also include any prepaid lease payments and lease incentives. Operating lease expense (excluding variable lease costs) is recognized on a straight-line basis over the lease term.

The Company allocates the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed, based on their estimated fair values. The excess of the purchase price over the fair values of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.

The Company uses its best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. Assumptions used to estimate the fair value of the intangible assets include, but are not limited to, projected revenue growth, projected operating expenses, and technology migration curves. These estimates are inherently uncertain and subject to refinement and, as a result, actual results may differ from estimates.

During the measurement period, which may not be later than one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Consolidated Statements of Operations.

The Company acquires intangible assets separately or in connection with business combinations. Intangible assets are measured at cost initially. Intangible assets with finite lives are amortized over their estimated useful life using the straight-line method. The amortization expense on intangible assets is recognized in the Consolidated Statements of Operations in the expense category consistent with the function of the intangible asset.

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate an asset’s carrying value may not be recoverable. When the projected undiscounted cash flows estimated to be generated by those assets are less than their carrying amounts, the assets are adjusted to their estimated fair value and an impairment loss is recorded as a component of operating income (expense).

Goodwill is tested for impairment at least annually during the fourth quarter of the Company’s fiscal year and more often if and when circumstances indicate that the carrying value may be impaired. The Company’s reporting unit is at the operating segment level. The Company performs its goodwill impairment test at the level of its operating segment, as there are no levels below the operating segment level for which discrete financial information is prepared and regularly reviewed by the Company’s CODM. A qualitative assessment is performed to determine whether it is more likely than not that the fair value of its operating segment is less than its carrying amount. If the operating segment does not pass the qualitative assessment, the carrying amount of the operating segment, including goodwill, is compared to fair value and goodwill is considered impaired if the carrying value exceeds its fair value. Any excess is recognized as an impairment loss in the current period earnings.

The Company recognizes compensation expense related to all stock-based awards, including restricted stock units (“RSU”) and restricted stock awards (“RSA”) issued to the Company’s employees in exchange for their service, based on the estimated fair value of the awards on the grant date. The fair value of each RSU or RSA is based on the fair value of the Company’s Class A Common Stock on the date of grant.

The Company recognizes costs related to stock-based awards, net of estimated forfeitures, over the awards’ requisite service period on a straight-line basis, which is generally four years. The Company estimates forfeitures based on historical experience. The respective expenses are recognized as employee benefits and classified in the Consolidated Statements of Operations according to the activities that the employees perform.

The Company offers various defined contribution plans for its U.S. and non-U.S. employees. The Company matches a portion of employee contributions each pay period, subject to maximum aggregate matching amounts, or contributes based on local legislative rates for eligible employees. Total defined contribution plan expense was $137.3 million, $114.5 million, and $96.3 million for fiscal years 2026, 2025, and 2024, respectively.

Research and development costs are expensed as incurred and consist of the employee, software, and hardware costs incurred for the development of new apps, AI agents and products, enhancements and updates of existing offerings and quality assurance activities. The costs incurred for the development of the Company’s cloud-based platform and internal use software are evaluated for capitalization during the development phase. The Company did not capitalize software development costs on its Consolidated Balance Sheet for the periods presented.

Financial instruments potentially exposing the Company to credit risk consist primarily of cash, cash equivalents, accounts receivable, derivative contracts and investments. The Company holds cash at financial institutions that management believes are high credit, quality financial institutions and invests in investment grade securities rated A- and above and debt securities. The Company’s derivative contracts expose it to credit risk to the extent that the counterparties may be unable to meet the terms of the arrangement. The Company enters into master netting agreements with select financial institutions to reduce its credit risk and trades with several counterparties to reduce its concentration risk with any single counterparty. The Company does not have significant exposure to counterparty credit risk at this time. In addition, the Company does not require nor is required to post collateral of any kind related to any foreign currency derivatives.

base is highly diversified, thereby limiting credit risk. The Company manages credit risk with customers by closely monitoring its receivables and contract assets. The Company continuously monitors outstanding receivables locally to assess whether there is objective evidence that outstanding accounts receivables and contract assets are credit-impaired. As of June 30, 2026 and June 30, 2025, no customer represented more than 10% of the total accounts receivable balance. For fiscal years ended June 30, 2026, 2025, and 2024, no customer represented more than 10% of the total revenues.

The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities represent temporary differences between the carrying amounts of assets and liabilities in the consolidated financial statements and their corresponding tax basis used in the computation of taxable income. The Company measures deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be reversed. The Company recognizes the effect on deferred tax assets and liabilities of a change in tax rates within the provision for income taxes as expense and income in the period that includes the enactment date. The Company accounts for the tax impact of including Global Intangible Low-Taxed Income in U.S. taxable income as a period cost. A valuation allowance is established if it is more likely than not that all or a portion of the deferred tax asset will not be realized.

Changes in deferred tax assets or liabilities are recognized as a component of benefit from (provision for) income taxes in the Consolidated Statements of Operations, except where they relate to items that are recognized in other comprehensive income or directly in equity, in which case the related deferred tax is also recognized in other comprehensive income or equity, respectively. Where deferred tax arises from the initial accounting for a business combination, the tax effect is included in the accounting for the business combination.

Deferred tax assets are regularly evaluated for future realization and reduced by a valuation allowance to an amount for which realization is more likely than not. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing temporary differences, projected future taxable income, tax planning strategies, carry back potential if permitted under the tax law, and results of recent operations. Significant management judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the likely timing and the amount of future taxable income, together with future tax-planning strategies. Assumptions about the generation of future taxable income depend on management’s estimates of future cash flows, future business expectations, capital expenditures, dividends, and other capital management transactions. Management judgment is also required in relation to the application of income tax legislation, which involves complexity and an element of uncertainty. In the event there is a change in the Company’s assessment of its ability to recover deferred tax assets, the income tax provision would be adjusted accordingly, resulting in a corresponding adjustment to the Consolidated Statements of Operations.

Uncertain tax positions are recorded in accordance with Accounting Standards Codification Topic 740 Income Taxes (“ASC 740”), Income Taxes. ASC 740 specifies a two-step process in which (1) the Company determines whether it’s more likely than not that tax positions will be sustained on the basis of the technical merits of the position, and (2) for those positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more likely than not to be realized upon ultimate settlement with the related tax authority. The Company considers many factors when evaluating uncertain tax positions, which involve significant judgment and may require periodic reassessment. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense. For details of taxation, please refer to Note 18, “Income Taxes.”

In December 2023, the FASB issued Accounting Standards Update (“ASU”) No. 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. This ASU is effective for fiscal years beginning after December 15, 2024. The Company adopted ASU 2023-09 on a prospective basis effective July 1, 2025. Refer to Note 18, “Income Taxes” for further information.

In November 2024, the FASB issued ASU No. 2024-03 “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures.” This ASU requires disaggregated disclosure of income statement expenses for public entities. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. This ASU is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and disclosures.

In July 2025, the FASB issued ASU 2025-05 “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets for Private Companies and Certain Not-for-Profit Entities,” which amends ASC 326-20 to provide a practical expedient and an accounting policy election (for all entities, other than public business entities that elect the practical expedient) related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under ASC 606. This ASU is effective for fiscal years beginning after December 15, 2025, and early adoption is permitted. The Company is currently evaluating the impact of the new guidance and does not expect it to have a material impact on its consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06 “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software.” This ASU makes targeted improvements to modernize the accounting for internally developed software subject to ASC 350-40. This ASU is effective for fiscal years beginning after December 15, 2027, and early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.
