NOTES TO CON DENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited) 1. Basis of Presentation General The accompanying unaudited condensed consolidated financial statements include the accounts of PTC Inc. and its wholly owned subsidiaries and have been prepared by management in accordance with accounting principles generally accepted in the United States of America (GAAP) and in accordance with the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. While we believe that the disclosures presented are adequate in order to make the information not misleading, these unaudited quarterly financial statements should be read in conjunction with our annual consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2025. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting only of those of a normal recurring nature, necessary for a fair statement of our financial position, results of operations and cash flows as of the dates and for the periods indicated. The September 30, 2025 Consolidated Balance Sheet included herein is derived from our audited consolidated financial statements. Unless otherwise indicated, all references to a year mean our fiscal year, which ends on September 30. Recently Adopted Accounting Pronouncements Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract In September 2025, the FASB issued ASU 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract, which expands the scope exceptions of the derivatives guidance and clarifies the guidance on share-based payments from a customer. Specifically, the ASU introduces a scope exception for contracts that are not exchange-traded and that have variables based on operations or activities specific to one of the parties of the contract. The ASU is effective for us in the first quarter of 2028, with early adoption permitted. We early adopted this standard prospectively in the second quarter of 2026. The adoption of this ASU did not have an impact on our consolidated financial statements and related disclosures. Pending Accounting Pronouncements Narrow-Scope Improvements for Interim Reporting In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which clarifies interim disclosure requirements and the applicability of Topic 270. The ASU will be effective for us in the first quarter of 2029, with early adoption permitted. We expect the adoption to result in disclosure changes only. 7 Table of Contents     Targeted Improvements to the Accounting for Internal-Use Software 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, which modernizes the accounting for internal-use software by eliminating project stage-based capitalization and clarifying the probable-to-complete threshold to commence the capitalization of software costs. The ASU will be effective for us in the first quarter of 2029, with early adoption permitted. The standard may be applied prospectively, retrospectively, or via a modified prospective transition method. We are currently evaluating the impact of this guidance on our consolidated financial statements and related disclosures. Measurements of Credit Losses for Accounts Receivable and Contract Assets 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, which provides a practical expedient to measure credit losses on accounts receivable and contract assets. The ASU will be effective for us in the first quarter of 2027, with early adoption permitted. We do not expect this standard to have a material impact on our consolidated financial statements. Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses and in January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. As clarified by ASU 2025-01, ASU 2024-03 will be effective for us for the year ended September 30, 2028. We expect the adoption to result in disclosure changes only. Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU will be effective for us in the fourth quarter of 2026. We expect the adoption to result in disclosure changes only. 2. Revenue from Contracts with Customers Receivables, Co ntract Assets and Contract Liabilities   (in thousands)   June 30, 2026     September 30, 2025   Short-term receivables   $ 824,107     $ 1,001,085   Long-term receivables   $ 420,719     $ 378,941   Contract asset   $ 13,780     $ 11,044   Deferred revenue   $ 712,527     $ 827,065   During the nine months ended June 30, 2026, we recognized $ 710.5 million of revenue that was included in Deferred revenue as of September 30, 2025. The remainder of the change in the Deferred revenue balance was driven by additional deferrals, primarily from new bil lings, offset by a decrease of approximately $ 56 million related to the Kepware and ThingWorx divestiture and a decrease resulting from changes in foreign currency exchange rates. Our multi-year, non-cancellable on-premises subscription contracts provide customers with an annual right to exchange software within the subscription with other software. As of June 30, 2026 and September 30, 2025, our total revenue liability was $ 44.1 million and $ 39.7 million, respectively, primarily associated with the annual right to exchange on-premises subscription software. 8 Table of Contents     Remaining Performance Obligations (RPO) Our contracts with customers include amounts allocated to performance obligations that will be satisfied and recognized as revenue at a later date. The value of RPO and timing of recognition may be impacted by several factors, including the performance obligation type, duration and timing of commencement, as well as foreign currency exchange rate fluctuations. As of June 30, 2026, RPO totaled $ 2,417.7 million, of which $ 712.5 million is recorded in Deferred revenue and $ 1,705.2 million is not yet recorded in the Consolidated Balance Sheets. Of the total, we expect to recognize approximately 54 % over the next 12 months, 28 % over the next 13 to 24 months, and the remaining amount thereafter.

Earnings per Share (EPS) and Common Stock EPS The following table presents the calculation for both basic and diluted EPS: (in thousands, except per share data)   Three months ended     Nine months ended       June 30, 2026     June 30, 2025     June 30, 2026     June 30, 2025   Net income   $ 118,780     $ 141,328     $ 876,021     $ 386,204   Weighted-average shares outstanding—Basic     114,677       119,913       117,401       120,106   Dilutive effect of restricted stock units     301       548       443       709   Weighted-average shares outstanding—Diluted     114,978       120,461       117,844       120,815   Earnings per share—Basic   $ 1.04     $ 1.18     $ 7.46     $ 3.22   Earnings per share—Diluted   $ 1.03     $ 1.17     $ 7.43     $ 3.20   T here were 0.8 million and 0.1 million anti-dilutive shares for the three and nine months ended June 30, 2026 , respectively. There were 0.4 million and 0.0 million anti-dilutive shares for the three and nine months ended June 30, 2025, respectively. Common Stock Repurchases Our Articles of Organization authorize us to issue up to 500 million shares of our common stock. Our Board of Directors has authorized us to repurchase up to $ 2 billion of our common stock in the period October 1, 2024 through September 30, 2026 (the “current authorization”), and up to $ 2 billion of our common stock in the period October 1, 2026 through September 30, 2028 . The amount remaining under the current authorization for repurchases as of June 30, 2026 is set forth in Part II, Item 2 Unregistered Sales of Equity Securities and Use of Proceeds of this Quarterly Report. On March 17, 2026, we entered into an accelerated share repurchase agreement ("ASR") with a major financial institution ("Bank") to repurchase $ 375 million of our outstanding common stock as a part of our existing share repurchase program. The ASR was funded with proceeds from the Kepware and ThingWorx divestiture. Upon execution of the ASR, we paid the Bank $ 375 million and received an initial delivery of 1.9 million shares, which represented 80 % ($ 300 million) of the value of the ASR contract. The remaining $ 75 million represented the amount held back by the Bank pending final settlement of the ASR, which occurred in June 2026 and resulted in the additional delivery of 0.8 million shares. The total shares repurchased under the ASR equaled $ 375 million divided by the average daily volume weighted-average price of our common stock during the term of the ASR less a fixed per-share discount. Settlement could have occurred in cash or shares at our election. We accounted for the ASR as an equity transaction; accordingly, this $ 75 million was recorded as a reduction to Additional paid-in capital in the second quarter of 2026. In addition to the ASR repurchases described above, in the third quarter and first nine months of 2026, we repurchased 4.3 million shares for $ 525 million and 7.0 million shares for $ 975 million, respectively, through open market transactions. In the first nine months of 2026 , we also paid $ 1.1 million in excise taxes related to share repurchases. In the third quarter and first nine months of 2025 , we repurchased 0.4 million shares for $ 75 million and 1.3 million shares for $ 225 million, respectively, through open market transactions. All shares repurchased are automatically restored to the status of authorized and unissued. 10 Table of Contents     5. Acquisitions and Divestitures Acquisition and transaction-related costs in the third quarter and first nine months of 2026 totaled $ 2.9 million and $ 40.0 million, respectively, compared to $ 1.6 million and $ 2.4 million in the third quarter and first nine months of 2025, respectively. These costs are classified in General and administrative expense in the accompanying Consolidated Statements of Operations. Kepware and ThingWorx Divestiture On March 13, 2026, we sold our Kepware and ThingWorx businesses pursuant to an Asset Purchase Agreement dated November 5, 2025 with Parrot US Buyer, L.P., a Delaware limited partnership (“Purchaser”), an entity controlled by investment funds affiliated with TPG Global, LLC. Total consideration for the transaction was $ 530.8 million, of which $ 523.3 million was received as cash proceeds in the second quarter of 2026 and $ 7.5 million is expected to be received in 2026. Consideration is subject to final working capital and indebtedness adjustments. Additional future contingent consideration of up to $ 125 million may be received by PTC in certain circumstances following a sale of the businesses by Purchaser. We have elected to defer the recognition of gains associated with contingent consideration unless and until they become realizable. Goodwill was allocated to the sold businesses based on a relative fair value allocation of total goodwill. The assets and liabilities of the Kepware and ThingWorx businesses were classified as held for sale in the first quarter of 2026. Upon closing the transaction, we sold $ 68.2 million of net assets and recognized a gain on the sale of $ 462.6 million, which is included in Other income, net. This resulted in tax expense of $ 95.6 million included in our income tax provision in the nine months ended June 30, 2026.   In connection with this divestiture, we entered into a Transition Services Agreement with Purchaser, whereby we agreed to provide certain transition services for up to 12 months from the date of sale. Income under such agreement offsets the operating costs to provide these services and is recognized as a reduction of the related operating expenses. 6. Goodwill and Intangible Assets During the third quarter of 2026, we completed our annual impairment test of goodwill, which was based on a qualitative assessment, and concluded that there was no impairment. A qualitative assessment is designed to determine whether we believe it is more likely than not that the fair values of our reporting units exceed their carrying values. A qualitative assessment includes a review of qualitative factors, including company-specific (financial performance and long-range plans), industry, and macroeconomic factors, and a consideration of the fair value of each reporting unit at the last valuation date. Goodwill and acquired intangible assets consisted of the following: (in thousands)   June 30, 2026     September 30, 2025       Gross Carrying Amount     Accumulated Amortization     Net Book Value     Gross Carrying Amount     Accumulated Amortization     Net Book Value   Goodwill               $ 3,398,303                 $ 3,493,316   Intangible assets with finite lives:                                     Purchased software   $ 547,640     $ 401,974     $ 145,666     $ 639,104     $ 472,357     $ 166,747   Capitalized software     22,877       22,877       —       22,877       22,877       —   Customer lists and relationships     1,088,385       480,308       608,077       1,149,262       505,202       644,060   Trademarks and trade names     31,822       19,766       12,056       38,179       24,323       13,856   Other     3,469       3,469       —       4,019       4,019       —   Total intangible assets with finite lives   $ 1,694,193     $ 928,394     $ 765,799     $ 1,853,441     $ 1,028,778     $ 824,663   Total goodwill and acquired intangible assets               $ 4,164,102                 $ 4,317,979     11 Table of Contents     Changes in Goodwill were as follows: (in thousands)       Balance, October 1, 2025   $ 3,493,316   Acquisitions     1,782   Divestiture of businesses     ( 82,204 ) Foreign currency translation adjustment     ( 14,591 ) Balance, June 30, 2026   $ 3,398,303   The aggregate amortization expense for intangible assets with finite lives is classified in our Consolidated Statements of Operations as follows: (in thousands)   Three months ended     Nine months ended       June 30, 2026     June 30, 2025     June 30, 2026     June 30, 2025   Amortization of acquired intangible assets   $ 11,991     $ 11,536     $ 36,075     $ 34,356   Cost of revenue     7,753       8,178       23,421       24,609   Total amortization expense   $ 19,744     $ 19,714     $ 59,496     $ 58,965     7. Fair Value Measurements The valuation hierarchy for disclosure of assets and liabilities reported at fair value prioritizes the inputs for such valuations into three broad levels: • Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2: quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; or • Level 3: unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. A financial asset's or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. Money market funds, time deposits, and corporate notes/bonds are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets. The principal market in which we execute our foreign currency derivatives is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants are generally large financial institutions. Our foreign currency derivatives’ valuation inputs are based on quoted prices and quoted pricing intervals from public data sources and do not involve management judgment. These contracts are typically classified within Level 2 of the fair value hierarchy. 12 Table of Contents     Our significant financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2026 and September 30, 2025 were as follows: (in thousands)   June 30, 2026       Level 1     Level 2     Level 3     Total   Financial assets:                         Cash equivalents (1)   $ 108,853     $ —     $ —     $ 108,853   Forward contracts     —       2,138       —       2,138   Option contracts     —       2,927       —       2,927     $ 108,853     $ 5,065     $ —     $ 113,918   Financial liabilities:                         Forward contracts     —       7,573       —       7,573     $ —     $ 7,573     $ —     $ 7,573     (in thousands)   September 30, 2025       Level 1     Level 2     Level 3     Total   Financial assets:                         Cash equivalents (1)   $ 38,031     $ —     $ —     $ 38,031   Forward contracts     —       6,007       —       6,007   Option contracts     —       6,228       —       6,228     $ 38,031     $ 12,235     $ —     $ 50,266   Financial liabilities:                         Forward contracts     —       4,773       —       4,773     $ —     $ 4,773     $ —     $ 4,773   (1) Money market funds and time deposits. Strategic Solar Energy Equity Investment During the third quarter of 2026, we invested $ 184.7 million in a solar energy project, of which $ 50.1 million has been contributed as of June 30, 2026. As of June 30, 2026, the unamortized balance of the investment was $ 113.1 million included in Other assets on the Consolidated Balance Sheet. As of June 30, 2026, remaining investment commitments totaled $ 113.5 million and $ 21.1 million included in Accrued expenses and other current liabilities and Other liabilities, respectively, on the Consolidated Balance Sheet. These are expected to be paid in 2026 and 2027. We have determined that this investment is a variable interest entity ("VIE"). Because we do not direct the activities that most significantly impact the economic performance of the project company, we are not the primary beneficiary. Therefore, the VIE is not consolidated within our financial statements. Our maximum exposure to the VIE is limited to our contributed capital and future capital commitments and a contingent deficit restoration obligation capped at 55 % of our aggregate capital contributions, which would arise only upon liquidation of the VIE and only to the extent PTC has a deficit capital account at the time of liquidation. 13 Table of Contents     8. Derivative Financial Instruments We enter into derivative transactions to manage our exposure to fluctuations in foreign exchange rates, specifically foreign currency forward contracts to manage our exposure related to monetary assets and liabilities denominated in foreign currencies and foreign exchange option contracts to manage our exposure related to forecasted cash flows. We do not enter into derivative transactions for trading or speculative purposes. The following table shows our derivative instruments measured at gross fair value as reflected in the Consolidated Balance Sheets: (in thousands)   Fair Value of Derivatives Designated As Hedging Instruments     Fair Value of Derivatives Not Designated As Hedging Instruments       June 30, 2026     September 30, 2025     June 30, 2026     September 30, 2025   Derivative assets (1) :                         Forward contracts   $ 34     $ 2,871     $ 2,104     $ 3,136   Option contracts   $ —     $ —     $ 2,927     $ 6,228   Derivative liabilities (2) :                         Forward contracts   $ 4,272     $ —     $ 3,301     $ 4,773   (1) As of June 30, 2026 and September 30, 2025 , current derivative assets are recorded in Other current assets in the Consolidated Balance Sheets. (2) As of June 30, 2026 and September 30, 2025 , current derivative liabilities are recorded in Accrued expenses and other current liabilities in the Consolidated Balance Sheets. Non-Designated Hedges We hedge our net foreign currency monetary assets and liabilities with foreign exchange forward contracts to reduce the risk that our earnings and cash flows will be adversely affected by changes in foreign currency exchange rates. These contracts have maturities of up to approximately three months . Generally, we do not designate these foreign currency forward contracts as hedges for accounting purposes and changes in the fair value of these instruments are recognized immediately in earnings. Because we enter into forward contracts only as an economic hedge, gains or losses on the underlying foreign-denominated balance are generally offset by the losses or gains on the forward contract. Gains and losses on forward contracts and foreign denominated receivables and payables are included in Other income, net. We hedge our forecasted U.S. Dollar cash flows with foreign exchange option contrac ts to reduce the risk that they will be adversely affected by changes in Euro or Japanese Yen exchange rates. These options have maturities of up to approximately fourteen months . We do not designate these foreign currency option contracts as hedges for accounting purposes and changes in the fair value of these instruments are recognized immediately in earnings. Because we enter into option contracts as an economic hedge, currency impacts on the Euro or Japanese Yen-denominated operations may be partially offset by gains on the option contracts. Gains and losses on foreign exchange option contracts are included in Other income, net. 14 Table of Contents     As of June 30, 2026 and September 30, 2025, we had outstanding forward and option contracts not designated as hedging instruments with notional amounts equivalent to the following: Currency Hedged (in thousands)   June 30, 2026     September 30, 2025   Euro / U.S. Dollar (1)   $ 762,849     $ 1,202,830   British Pound / U.S. Dollar     4,727       22,974   Israeli Shekel / U.S. Dollar     19,456       20,094   Indian Rupee / U.S. Dollar     74,490       53,465   Japanese Yen / U.S. Dollar (2)     12,971       131,284   Swiss Franc / U.S. Dollar     14,835       8,960   Swedish Krona / U.S. Dollar     18,770       21,568   New Taiwan Dollar / U.S. Dollar     14,404       23,098   All other     18,938       33,813   Total   $ 941,440     $ 1,518,086   (1) As of June 30, 2026 , $ 687.2 million of the Euro to U.S. Dollar outstanding notional amount relates to forward contracts and $ 75.6 million relates to option contracts. As of September 30, 2025 , $ 835.4 million of the Euro to U.S. Dollar outstanding notional amount relates to forward contracts and $ 367.4 million relates to option contracts . (2) As of June 30, 2026, $ 1.4 million of the Japanese Yen to U.S. Dollar outstanding notional amount relates to forward contracts and $ 11.6 million relates to option contracts. As of September 30, 2025 , $ 41.9 million of the Japanese Yen to U.S. Dollar outstanding notional amo unt relates to forward contracts and $ 89.4 million relates to option contracts. The following table shows the effect of our non-designated hedges on the Consolidated Statements of Operations for the three and nine months ended June 30, 2026 and June 30, 2025:  (in thousands)       Three months ended     Nine months ended       Location of Gain (Loss)   June 30, 2026     June 30, 2025     June 30, 2026     June 30, 2025   Net realized and unrealized gain (loss), excluding the underlying foreign currency exposure being hedged   Other income, net   $ ( 1,886 )   $ 4,021     $ ( 743 )   $ 3,661   In the three and nine months ended June 30, 2026, total foreign currency losses, net were $ 0.6 million and $ 2.5 million, respectively. In the three and nine months ended June 30, 2025, total foreign currency gains were $ 1.1 million and $ 0.0 million, respectively. Net Investment Hedges We translate balance sheet accounts of subsidiaries with foreign functional currencies into the U.S. Dollar using the exchange rate at each balance sheet date. Resulting translation adjustments are reported as a component of Accumulated other comprehensive loss on the Consolidated Balance Sheets. We designate certain foreign exchange forward contracts as net investment hedges against exposure on translation of balance sheet accounts of Euro and Japanese Yen functional subsidiaries. Net investment hedges partially offset the impact of Foreign currency translation adjustment recorded in Accumulated other comprehensive loss on the Consolidated Balance Sheets. All foreign exchange forward contracts are carried at fair value on the Consolidated Balance Sheets and the maximum duration of net investment hedge foreign exchange forward contracts is approximately three mo nths . Net investment hedge relationships are designated at inception, and effectiveness is assessed retrospectively on a quarterly basis using the net equity position of Euro and Japanese Yen functional subsidiaries. As the forward contracts are highly effective in offsetting exchange rate exposure, we record changes in these net investment hedges in Accumulated other comprehensive loss. Changes in the fair value of foreign exchange forward contracts due to changes in time value are excluded from the assessment of effectiveness. Our derivatives are not subject to any credit contingent features. We manage credit risk with counterparties by trading among several counterparties and we review our counterparties’ credit at least quarterly. 15 Table of Contents     As of June 30, 2026 and September 30, 2025, we had outstanding forward contracts designated as net investment hedges with notional amounts equivalent to the following: Currency Hedged (in thousands)   June 30, 2026     September 30, 2025   Euro / U.S. Dollar   $ 508,428     $ 480,198   Japanese Yen / U.S. Dollar     18,608       10,260   Total   $ 527,036     $ 490,458     The following table shows the effect of our derivative instruments designated as net investment hedges in the Consolidated Statements of Operations for the three and nine months ended June 30, 2026 and June 30, 2025: (in thousands)       Three months ended     Nine months ended       Location of Gain (Loss)   June 30, 2026     June 30, 2025     June 30, 2026     June 30, 2025   Gain (loss) recognized in Other comprehensive income (loss) ("OCI")   OCI   $ 6,226     $ ( 39,628 )   $ 14,386     $ ( 26,078 ) Gain (loss) reclassified from OCI to earnings   n/a   $ —     $ —     $ —     $ —   Gain recognized, excluded portion   Other income, net   $ 1,528     $ 1,743     $ 5,054     $ 4,072   Offsetting Derivative Assets and Liabilities We have entered into master netting arrangements for our foreign exchange contracts that allow net settlements under certain conditions. Although netting is permitted, it is currently our policy and practice to record all derivative assets and liabilities on a gross basis in the Consolidated Balance Sheets.

Income Taxes (in thousands)   Three months ended     Nine months ended       June 30, 2026     June 30, 2025     June 30, 2026     June 30, 2025   Income before income taxes   $ 152,440     $ 193,676     $ 1,102,214     $ 492,079   Provision for income taxes   $ 33,660     $ 52,348     $ 226,193     $ 105,875   Effective income tax rate     22 %     27 %     21 %     22 % The effective tax rate for the three months ended June 30, 2026 was lower than the effective tax rate for the three months ended June 30, 2025, primarily due to changes in the geographic mix of income before taxes. For the three and nine months ended June 30, 2026 , the provision for income taxes included $ 14.4 million of tax expense related to the Varian Medical Systems, Inc. v. Commissioner tax court ruling and a $ 7.2 million tax benefit related to a strategic solar energy investment. The nine months ended June 30, 2026 also included $ 95.6 million of tax expense related to the Kepware and ThingWorx divestiture and a $ 7.1 million income tax benefit related to the reversal of a prior-year tax charge associated with Internal Revenue Service (IRS) procedural guidance. The effective tax rate for the three and nine months ended June 30, 2025 reflected increased tax expense associated with the IRS procedural guidance described below. Additionally, t he nine months ended June 30, 2025 included a benefit of $ 10.4 million related to changes in tax reserves associated with prior years in foreign jurisdictions. In 2024, we recorded a $ 14.4 million tax benefit for additional foreign tax credits that became available as a result of a U.S. Tax Court ruling in Varian Medical Systems, Inc. v. Commissioner , issued on August 26, 2024. The ruling addressed the U.S. tax treatment of deemed foreign dividends recognized during the transition year of the Tax Cuts and Jobs Act (our fiscal 2018). On April 8, 2026, the U.S. Tax Court granted summary judgment in favor of the IRS, and as a result, we reversed the previously recognized tax benefit. During the nine months ended June 30, 2026, we recognized tax expense of $ 95.6 million related to the divestiture of the Kepware and ThingWorx businesses. This amount reflects a reduction from the $ 102.4 million tax expense recorded during the quarter ended March 31, 2026, resulting from updates to the estimated tax impact of the transaction. In 2024, we requested consent from the IRS to change our tax accounting method for the treatment of certain deductions. In the quarter ended December 31, 2025, upon receiving consent from the IRS, we released the reserve related to the procedural guidance. As a result, we recognized a $ 7.1 million income tax benefit for the nine months ended June 30, 2026, primarily related to the reversal of the accrued interest and the associated effects on GILTI and FDII. In the normal course of business, PTC and its subsidiaries are examined by various taxing authorities, including the IRS in the U.S. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. We are currently under audit by tax authorities in several jurisdictions. Audits by tax authorities typically involve examination of the deductibility of certain permanent items, transfer pricing, limitations on net operating losses and tax credits. As of June 30, 2026 and September 30, 2025, income taxes payable and income tax accruals recorded on the accompanying Consolidated Balance Sheets were $ 130.5 million ($ 85.2 million in Accrued income taxes and $ 45.3 million recorded in Other Liabilities) and $ 179.1 million ($ 28.7 million in Accrued income taxes and $ 150.4 million in Other liabilities), respectively. 17 Table of Contents     As of June 30, 2026 and September 30, 2025 , we had unrecognized tax benefits of $ 50.9 million and $ 157.7 million, respectively. This decrease predominantly relates to the release of the reserve established in 2025 related to the IRS procedural guidance, primarily resulting in corresponding decreases to Deferred tax assets and the reserve for unrecognized tax benefits within Other liabilities. Additionally, this resulted in a $ 7.1 million net income tax benefit as described above. If all our unrecognized tax benefits as of June 30, 2026 were to become recognizable in the future, we would record a benefit to the income tax provision of $ 50.9 million, which would be partially offset by an increase in the U.S. valuation allowance of $ 6.0 million. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in favorable or unfavorable changes in our estimates. We believe it is reasonably possible that within the next 12 months the amount of unrecognized tax benefits related to the resolution of multi-jurisdictional tax positions could be reduced by up to $ 1 million. On July 4, 2025, the “One Big Beautiful Bill Act” (the “Act”) was enacted into law. The Act includes changes to U.S. tax law that became applicable to us beginning in 2026. These changes include provisions allowing accelerated tax deductions for qualified property and research expenditures. Our financials reflect the impact of the provisions of the Act that are applicable beginning 2026. Tax Benefits of Strategic Solar Energy Equity Investment During the third quarter of 2026, we invested in a solar energy project as described in Note 7. Fair Value Measurements . We have elected to account for the investment using the proportional amortization method, under which the cost of the investment is amortized over the period that we expect to receive tax benefits from the project. Amortization of and tax benefits associated with the investment are presented within Provision for income taxes on the Consolidated Statement of Operations. The tax benefits associated with the investment reduce cash taxes paid and benefit operating cash flows. During the third quarter of 2026, we recognized $ 78.8 million of investment tax credits and other tax benefits, partially offset by $ 71.6 million of investment amortization.   10. Debt As of June 30, 2026 and September 30, 2025, we had the following debt obligations: (in thousands)   June 30, 2026     September 30, 2025   4.000% Senior notes due 2028   $ 500,000     $ 500,000   Credit facility revolver line (1)(2)     475,000       231,250   Credit facility term loan (1)(2)     450,074       468,750   Total debt     1,425,074       1,200,000   Unamortized debt issuance costs for the senior notes (3)     ( 1,759 )     ( 2,566 ) Total debt, net of issuance costs (4)   $ 1,423,315     $ 1,197,434   (1) Unamortized debt issuance costs related to the credit facility were $ 2.7 million included in Other current assets and $ 2.1 million included in Other assets on the Consolidated Balance Sheet as of June 30, 2026 and $ 2.7 million included in Other current assets and $ 3.3 million included in Other assets on the Consolidated Balance Sheet as of September 30, 2025 . (2) The stated maturity date under the credit facility on which both the revolver line and the term loan will mature and all amounts then outstanding will become due and payable is January 3, 2028 . The term loan began amortizing in March 2024, with payments remaining of $ 6.3 mi llion in 2026, $ 25.0 million in 2027, and $ 418.7 million in 2028. (3) As of June 30, 2026 and September 30, 2025, all unamortized debt issuance costs for the senior notes were included in Long-term debt on the Consolidated Balance Sheets. (4) Debt associated with the credit facility that was classified as short term was $ 25.1 million and $ 25.0 million as of June 30, 2026 and September 30, 2025 , respectively. 18 Table of Contents     Senior Unsecured Notes In February 2020, we issued $ 500 million in aggregate principal amount of 4.0 % senior, unsecured long-term debt at par value, due in 2028 (the 2028 notes). As of June 30, 2026, the total estimated fair value of the 2028 notes was approximately $ 490.0 million based on quoted prices for the notes on that date. We were in compliance with all the covenants for the 2028 notes as of June 30, 2026. Credit Agreement Our credit facility consists of (i) a $ 1.25 billion revolving credit facility, (ii) a $ 500 million term loan credit facility, and (iii) an incremental facility pursuant to which we may incur additional term loan tranches or increase the revolving credit facility. As of June 30, 2026, unused commitments under our revolving credit facility were $ 774.9 million and the amount available to borrow was $ 757.5 million. As of June 30, 2026, the fair value of our credit facility approximates its book value. PTC and certain foreign subsidiaries are eligible borrowers under the credit facility. As of June 30, 2026 , $ 46.3 million was borrowed by an eligible foreign subsidiary borrower. We were in compliance with all financial and operating covenants of the credit facility as of June 30, 2026. Loans under the credit facility bear interest at variable rates. As of June 30, 2026, the annual rate for borrowings outstanding was 5.0 % . A quarterly revolving commitment fee on the undrawn portion of the revolving credit facility is required, ranging from 0.175 % to 0.325 % per annum, based upon our total leverage ratio. Interest We incurred interest expense on our debt of $ 15.8 million and $ 48.4 million in the third quarter and first nine months of 2026, respectively, and $ 18.4 million and $ 60.1 million in the third quarter and first nine months of 2025, respectively. The average interest rate on borrowings outstanding was approximately 4.6 % and 4.7 % during the third quarter and first nine months of 2026, respectively, and 5.0 % and 4.9 % during the third quarter and first nine months of 2025 , respectively. 11. Commitments and Contingencies Guarantees and Indemnification Obligations We enter into standard indemnification agreements with our customers and business partners in the ordinary course of our business. Under such agreements, we typically indemnify, hold harmless, and agree to reimburse the indemnified party for losses suffered or incurred by the indemnified party, in connection with patent, copyright or other intellectual property infringement claims by any third party with respect to our products. Indemnification may also cover other types of claims, including claims relating to certain data breaches. These agreements typically limit our liability with respect to indemnification claims other than intellectual property infringement claims. Historically, our costs to defend lawsuits or settle claims relating to such indemnity agreements have been minimal and, accordingly, we believe the estimated fair value of liabilities under these agreements is immaterial. We warrant that our software products will perform in all material respects in accordance with our standard published specifications during the term of the license. Additionally, we generally warrant that our consulting services will be performed consistent with generally accepted industry standards and, in the case of fixed price services, the agreed-upon specifications. In most cases, liability for these warranties is capped. If necessary, we would provide for the estimated cost of product and service warranties based on specific warranty claims and claim history; however, we have not incurred significant cost under our product or services warranties. As a result, we believe the estimated fair value of these liabilities is immaterial. 19 Table of Contents     12. Segments We operate as a single operating and reportable segment. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker ("CODM") in deciding how to allocate resources and in assessing performance. Our CODM is our Chief Executive Officer . The CODM evaluates financial performance and allocates resources based on consolidated results, including consolidated net income. The total assets of the segment are reported on the Consolidated Balance Sheets. The following table presents revenue, significant expenses, and consolidated net income for our reportable segment: (in thousands)   Three months ended     Nine months ended       June 30, 2026     June 30, 2025     June 30, 2026     June 30, 2025   Revenue   $ 600,049     $ 643,937     $ 2,060,177     $ 1,845,431   Costs and expenses:                               Cost of revenue, adjusted (1)     96,228       96,556       298,791       286,764         Operating expenses, adjusted (2)     255,302       262,210       792,581       782,856         Other segment items (3)     129,739       143,843       92,784       389,607   Consolidated net income   $ 118,780     $ 141,328     $ 876,021     $ 386,204   (1) Cost of revenue, adjusted excludes stock-based compensation and amortization of acquired intangible assets .

(3) Other segment items include stock-based compensation; amortization of acquired intangible assets; acquisition and transaction-related charges; Impairment and other charges, net; Other income, net; and Provision for income taxes. 13. Subsequent Events Share Repurchases and Borrowings under Credit Facility We repurchased $ 273.7 million of our common stock in July 2026, financed primarily with $ 301.3 million of net borrowings under our credit facility.   20 Table of Contents     ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS O F FINANCIAL CONDITION AND RESULTS OF OPERATIONS Business Overview PTC is a global software company headquartered in Boston, Massachusetts. We employ over 7,000 people and support more than 30,000 customers globally. We primarily serve customers in the following industry verticals: • Industrials • Federal, Aerospace and Defense • Electronics and High Tech • Automotive • Medical Technology and Life Sciences Our customers are focused on improving their competitiveness in the face of global competition and increasing product complexity, and our suite of software offerings is a strategic enabler of this and their digital transformation initiatives. Given the breadth and openness of our portfolio, we enable the Intelligent Product Lifecycle: establishing a strong product data foundation in the engineering department and democratizing the access and use of that data across the enterprise to drive cross-functional collaboration, accelerate new product introduction timelines, and deliver higher product quality. By embracing the Intelligent Product Lifecycle, our customers establish the quality, consistency, and traceability of product data, ensuring the data is up-to-date, accessible, reliable, and actionable. Our customers can then go on to use this data to break down silos, streamline workflows, and achieve interoperability across departments, functions, and systems. This includes the growing emphasis on AI-driven transformation across our customers’ teams, operations, and processes. A product data foundation is the backbone of AI-driven transformation. Our business is based on a subscription model and approximately 95% of our 2025 and 2026 year-to-date revenue was recurring in nature. Compared to a perpetual license model, our subscription model naturally drives higher customer engagement and retention and provides better business predictability. This, in turn, enables us to make steady and sustained investments to support our customers and pursue mid-to-long-term growth opportunities. Forward-Looking Statements Statements in this document that are not historic facts, including statements about our future operating, financial and growth expectations, and potential stock repurchases are forward-looking statements that involve risks and uncertainties that could cause actual results to differ materially from those projected. These risks include: the macroeconomic and/or global manufacturing climates may not improve or may deteriorate due to, among other factors, the effects of import tariffs, threats of additional and reciprocal import tariffs, global trade and geopolitical tensions and uncertainty, including the recent military conflict in Iran, volatile foreign exchange rates, high interest rates or increases in interest rates, inflation, and tightening of credit standards and availability, any of which could cause customers to delay or reduce purchases of new software, adopt competing software solutions, reduce the number of subscriptions they carry, or delay payments to us, which would adversely affect our ARR (Annual Run Rate) and/or financial results and cash flow and growth; our investments in our software solutions, including the integration of artificial intelligence (AI) capabilities into our software solutions, may not drive expansion of those solutions and/or generate the ARR and/or cash flow we expect if those capabilities are not made available when or as we expect, if customers are slower to adopt those solutions than we expect, or if customers adopt competing solutions; customers may not build the product data 21 Table of Contents     foundations essential for the AI-driven transformation of their business when or as we expect, which could adversely affect our ARR and/or financial results and cash flow and growth; our go-to-market realignment and related initiatives may not generate the ARR and/or financial results or cash flow when or as we expect; the proceeds we receive under the Transition Services Agreement entered into in connection with the divestiture of the Kepware and ThingWorx businesses may be lower than expected and/or may not offset our expenses and/or the cash flow impact of the divestiture to the extent expected; the divestiture and/or performance of the Transition Services Agreement may disrupt our business to a greater extent than we expect; other uses of cash or our credit facility limits could limit or preclude the return of excess cash to shareholders by way of share repurchases, or could change the amount and timing of any share repurchases; and foreign exchange rates may differ materially from those we expect. In addition, our assumptions concerning our future GAAP and non-GAAP effective income tax rates are based on estimates and other factors that could change, including changes to tax laws in the U.S. and other countries and the geographic mix of our revenue, expenses, and profits. Other risks and uncertainties that could cause actual results to differ materially from those projected are described below throughout or referenced in Part II, Item 1A. Risk Factors of this report. Our Operating and Non-GAAP Financial Measures Our discussion of results includes discussion of our ARR operating measure, non-GAAP financial measures, and disclosure of our results on a constant currency basis. ARR and our non-GAAP financial measures are described below in Operating and Non-GAAP Financial Measures . The methodology used to calculate constant currency disclosures is described in Results of Operations - Impact of Foreign Currency Exchange on Results of Operations . You should read those sections to understand our operating measure, non-GAAP financial measures, and constant currency disclosures. Given the divestiture of our Kepware and ThingWorx businesses in Q2’26, we are also providing ARR excluding those divested businesses, which removes ARR attributable to those businesses from the applicable prior periods to facilitate meaningful period-to-period comparisons of our continuing business. Executive Overview ARR was $2.41 billion as of the end of Q3'26, flat with Q3'25, and grew 2% on a constant currency basis, with growth impacted by the Q2'26 divestiture of the Kepware and ThingWorx businesses. ARR growth excluding the divested businesses in Q3'26 compared to Q3'25 was 7% (9% constant currency). Cash provided by operating activities grew 7% to $261 million in Q3'26 compared to Q3'25. Free cash flow grew 3% to $249 million in Q3'26 compared to Q3'25, impacted by higher capital expenditures related to moving a major R&D center to a new office. In Q3'26, we made $9 million of divestiture-related payments. Our cash flow growth is attributable to resilient top-line growth due to our subscription business model and operational discipline. In Q3'26, we repurchased $525 million of outstanding shares, of which $500 million was paid in the quarter, partially funded by $225 million of net debt borrowings under our credit facility. Revenue decreased 7% (8% constant currency) in Q3'26 compared to Q3'25, reflecting the divestiture of the Kepware and ThingWorx businesses in Q2'26 as well as lower license revenue due primarily to the shortened duration of a single large contract renewal and expansion. There was $46 million of revenue attributable to Kepware and ThingWorx in Q3'25. Operating margin decreased by approximately 480 basis points in Q3'26 compared to Q3'25 and diluted earnings per share decreased 12% to $1.03 in Q3'26 compared to Q3'25, primarily due to lower revenue in Q3'26 compared to Q3'25.   22 Table of Contents     Results of Operations (Dollar amounts in millions, except per share data)   Three months ended     Percent Change       June 30, 2026     June 30, 2025     Actual     Constant Currency (1)   ARR   $ 2,412.4     $ 2,415.6       (0 )%     2 % ARR excluding divested businesses (2)   $ 2,412.4     $ 2,255.6       7 %     9 %                         Total recurring revenue (3)   $ 576.0     $ 613.6       (6 )%     (7 )% Perpetual license     0.7       7.8       (91 )%     (91 )% Professional services     23.3       22.6       3 %     3 % Total revenue     600.0       643.9       (7 )%     (8 )% Total cost of revenue     109.6       110.0       (0 )%     (1 )% Gross margin     490.5       533.9       (8 )%     (9 )% Operating expenses     324.0       324.1       (0 )%     (1 )% Operating income   $ 166.5     $ 209.8       (21 )%     (21 )% Non-GAAP operating income (1)   $ 248.5     $ 285.2       (13 )%     (13 )% Operating margin     27.7 %     32.6 %             Non-GAAP operating margin (1)     41.4 %     44.3 %             Diluted earnings per share   $ 1.03     $ 1.17               Non-GAAP diluted earnings per share (1)   $ 1.58     $ 1.64                                       Cash provided by operating activities   $ 260.6     $ 243.9               Capital expenditures     (11.3 )     (1.9 )             Free cash flow   $ 249.3     $ 242.0                   (Dollar amounts in millions, except per share data)   Nine months ended     Percent Change       June 30, 2026     June 30, 2025     Actual     Constant Currency (1)   ARR   $ 2,412.4     $ 2,415.6       (0 )%     2 % ARR excluding divested businesses (2)   $ 2,412.4     $ 2,255.6       7 %     9 %                         Total recurring revenue (3)   $ 1,976.7     $ 1,739.4       14 %     10 % Perpetual license     13.3       23.0       (42 )%     (43 )% Professional services     70.2       83.0       (15 )%     (17 )% Total revenue     2,060.2       1,845.4       12 %     9 % Total cost of revenue     340.9       328.1       4 %     3 % Gross margin     1,719.2       1,517.3       13 %     10 % Operating expenses     1,035.8       968.5       7 %     5 % Operating income   $ 683.4     $ 548.8       25 %     18 % Non-GAAP operating income (1)   $ 968.8     $ 775.8       25 %     19 % Operating margin     33.2 %     29.7 %             Non-GAAP operating margin (1)     47.0 %     42.0 %             Diluted earnings per share   $ 7.43     $ 3.20               Non-GAAP diluted earnings per share (1)   $ 6.21     $ 4.53                                       Cash provided by operating activities   $ 851.3     $ 763.7               Capital expenditures     (16.3 )     (7.5 )             Free cash flow   $ 835.0     $ 756.2               (1) See Operating and Non-GAAP Financial Measures below for a reconciliation of our GAAP results to our non-GAAP financial measures and Impact of Foreign Currency Exchange on Results of Operations below for a description of how we calculate our results on a constant currency basis. (2) ARR excluding divested businesses excludes ARR attributable to the Kepware and ThingWorx businesses from the prior‑year period to facilitate period‑to‑period comparison following the Q2'26 divestiture of those businesses. (3) Recurring revenue is comprised of on-premises subscription, perpetual support, SaaS, and hosting services revenue.   23 Table of Contents     Impact of Foreign Currency Exchange on Results of Operations Approximately 55% of our revenue and 30% of our expenses are transacted in currencies other than the U.S. Dollar. Because we report our results of operations in U.S. Dollars, currency translation, particularly changes in the Euro, Yen, Shekel, and Rupee relative to the U.S. Dollar, affects our reported results. Our constant currency disclosures are calculated by multiplying the results in local currency for the quarterly periods for FY'26 and FY'25 by the exchange rates in effect on September 30, 2025. If reported results for the nine months ended June 30, 2026 were converted into U.S. Dollars using the rates in effect as of September 30, 2025, ARR would have been higher by $36 million, revenue would have been higher by $9 million, and expenses would have been materially consistent. If reported results for the nine months ended June 30, 2025 were converted into U.S. Dollars using the rates in effect as of September 30, 2025, ARR would have been lower by $12 million, revenue would have been higher by $61 million, and expenses would have been higher by $21 million. Revenue Under ASC 606, the value, mix, and duration of contract types (support, SaaS, on-premises subscription) commencing in any given period can have a material impact on revenue in the period, and as a result can impact the comparability of reported revenue period over period. We recognize revenue for the license portion of on-premises subscription contracts when we deliver the licenses to the customer, typically on the start date, and we recognize revenue on the support portion of on-premises subscription contracts and stand-alone support contracts ratably over the term. Revenue from our cloud services (primarily SaaS) contracts is recognized ratably. Given the different value, mix, and duration of contracts commencing in any period, year-over-year or sequential revenue can vary significantly.

Software revenue attributable to Kepware and ThingWorx was $45 million and $131 million in Q3'25 and the first nine months of FY'25, respectively. In addition to the impact of the divestiture, software revenue in Q3’26 was also impacted by a decrease in license revenue, reflecting the shortened duration of a single large contract renewal and expansion in the period, offset by growth in support and cloud services revenue. Software revenue growth in the first nine months of FY'26 was driven by license revenue growth, which reflects the value and duration of contracts that commenced in the period. Support and cloud services revenue growth in the first nine months of FY'26 compared to the corresponding FY'25 period was driven by growth in both CAD and PLM. Professional services revenue decreased in the first nine months of FY'26 as we continue to execute our strategy of leveraging partners to deliver services rather than contracting to deliver services ourselves. 24 Table of Contents     Software Revenue by Product Group (Dollar amounts in millions)   Three months ended     Percent Change     Nine months ended     Percent Change       June 30, 2026     June 30, 2025     Actual     Constant Currency     June 30, 2026     June 30, 2025     Actual     Constant Currency   PLM   $ 335.8     $ 382.1       (12 )%     (13 )%   $ 1,215.6     $ 1,074.1       13 %     10 % CAD     240.9       239.2       1 %     0 %     774.3       688.3       12 %     9 % Software revenue   $ 576.7     $ 621.3       (7 )%     (8 )%   $ 1,989.9     $ 1,762.4       13 %     10 % PLM software revenue decreased in Q3'26 compared to Q3'25, primarily driven by the impact of the divestiture of the Kepware and ThingWorx businesses, as well as lower license revenue in Europe. PLM software revenue growth in the first nine months of FY'26 was driven by Windchill license revenue growth in the Americas and Europe, offset by the impact of the divestiture. PLM ARR decreased 4% (2% constant currency) from Q3’25 to Q3'26, reflecting the impact of the divestiture of the Kepware and ThingWorx businesses. PLM ARR excluding the divested businesses grew 8% (10% constant currency), primarily driven by Windchill and Codebeamer. PLM ARR decreased 4% (4% constant currency) in the Americas, 4% (2% constant currency) in Europe and 2% (5% increase in constant currency) in Asia Pacific from Q3'25 to Q3'26. PLM ARR excluding the divested businesses grew 9% (9% constant currency) in the Americas, 9% (16% constant currency) in Asia Pacific, and 6% (9% constant currency) in Europe from Q3'25 to Q3'26, primarily driven by Windchill in all regions, with contribution from Codebeamer in Europe and Asia Pacific. CAD software revenue was flat year-over-year in Q3'26 due to lower license revenue. CAD software revenue growth in the first nine months of FY'26 was driven by Creo growth in all regions.

License gross margin changes in Q3'26 and the first nine months of FY'26 compared to the corresponding FY'25 periods were in line with changes in license revenue. Cost of license revenue was higher in the first nine months of FY'26 compared to the first nine months of FY'25, primarily due to higher royalty expenses. 25 Table of Contents     Support and cloud services gross margin growth in Q3'26 and the first nine months of FY'26 compared to the corresponding FY'25 periods was in line with support and cloud services revenue growth. Cost of support and cloud services revenue increased 7% in the first nine months of FY'26, primarily due to higher cloud and software subscription-related costs and compensation-related costs. Professional services gross margin increased in Q3'26 compared to Q3'25 due to an increase in professional services revenue. Professional services gross margin decreased in the first nine months of FY'26, primarily due to a sharper decrease in professional services revenue than in professional services expense. The decrease in professional services revenue and costs is due to our continued execution of our strategy of leveraging partners to deliver services rather than contracting to deliver services ourselves.   Operating Expenses (Dollar amounts in millions)   Three months ended           Nine months ended             June 30, 2026     June 30, 2025     Percent Change     June 30, 2026     June 30, 2025     Percent Change   Sales and marketing   $ 136.3     $ 141.8       (4 )%   $ 417.3     $ 424.3       (2 )% % of total revenue     23 %     22 %           20 %     23 %       Research and development   $ 115.7     $ 116.6       (1 )%   $ 359.8     $ 343.2       5 % % of total revenue     19 %     18 %           17 %     19 %       General and administrative   $ 60.0     $ 54.1       11 %   $ 222.6     $ 162.5       37 % % of total revenue     10 %     8 %           11 %     9 %       Amortization of acquired intangible assets   $ 12.0     $ 11.5       4 %   $ 36.1     $ 34.4       5 % % of total revenue     2 %     2 %           2 %     2 %       Impairment and other charges, net   $ —     $ —       0 %   $ —     $ 4.2       (100 )% % of total revenue     0 %     0 %           0 %     0 %       Total operating expenses   $ 324.0     $ 324.1       (0 )%   $ 1,035.8     $ 968.5       7 % Total headcount in Q3'26 decreased 5% compared to Q3'25 due to the divestiture of the Kepware and ThingWorx businesses. Operating expenses in Q3'26 decreased compared to Q3'25, primarily due to: • income under the Transition Services Agreement associated with the divestiture of the Kepware and ThingWorx businesses, which is primarily included in General and administrative; partially offset by: • higher stock-based compensation expense and travel-related expenses. Operating expenses in the first nine months of FY'26 increased compared to the first nine months of FY'25, primarily due to the following: • $40 million in charges associated with the divestiture of the Kepware and ThingWorx businesses (included in General and administrative); • a $30 million increase in compensation expense (excluding stock-based compensation expense and severance expense), driven by headcount growth prior to the divestiture, annual merit increases, and expense related to accrued cash bonuses; • a $22 million increase in stock-based compensation, driven by the timing and value of grants and the increase in the number of performance-based grants, offset by lower stock-based bonus expense; and • an $11 million increase in travel-related expenses; 26 Table of Contents     partially offset by: • a $20 million decrease in severance costs primarily related to our FY'25 go-to-market realignment (which was mainly included in Sales and marketing); and • income under the Transition Services Agreement associated with the divestiture, which is primarily included in General and administrative.

Interest expense decreased in Q3'26 and the first nine months of FY'26 compared to the corresponding FY'25 periods due to lower debt balances during FY'26 and lower interest rates.

For the three and nine months ended June 30, 2026, the provision for income taxes included $14 million of tax expense related to the Varian Medical Systems, Inc. v. Commissioner tax court ruling and a $7 million tax benefit related to a strategic solar energy investment, each as discussed in Note 9. Income Taxes . For the first nine months of FY'26, the provision for income taxes also included a $96 million tax expense related to the Kepware and ThingWorx divestiture and a $7 million tax benefit related to the reversal of a prior-year tax charge associated with IRS procedural guidance, as described in Note 9. Income Taxes . The effective tax rate for the first nine months of FY'25 reflected increased tax expense associated with the IRS procedural guidance described in Note 9. Income Taxes . Additionally, the first nine months of FY’25 included a benefit of $10 million related to changes in tax reserves associated with prior years in foreign jurisdictions. 27 Table of Contents     On July 4, 2025, the “One Big Beautiful Bill Act” (the “Act”) was enacted into law. The Act includes changes to U.S. tax law that are applicable to us beginning in FY'26. These changes include provisions allowing accelerated tax deductions for qualified property and research expenditures. Our financials reflect the impact of the provisions of the Act that are applicable beginning FY'26. Critical Accounting Policies and Estimates There were no material changes to our critical accounting policies and estimates as set forth under the heading Critical Accounting Policies and Estimates in Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of our 2025 Annual Report on Form 10-K. Recent Accounting Pronouncements In accordance with recently issued accounting pronouncements, we will be required to comply with certain changes in accounting rules and regulations. Refer to Note 1. Basis of Presentation to the Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q, which is incorporated herein by reference, for all recently issued accounting pronouncements. We are evaluating the impact of ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software and have not yet determined whether they will have a material impact.   Liquidity and Capital Resources (in millions)   June 30, 2026     September 30, 2025   Cash and cash equivalents   $ 351.5     $ 184.4   Restricted cash     0.6       0.6   Total   $ 352.0     $ 185.0                 (in millions)   Nine months ended       June 30, 2026     June 30, 2025   Net cash provided by operating activities   $ 851.3     $ 763.7   Net cash provided by (used in) investing activities   $ 479.8     $ (28.6 ) Net cash used in financing activities   $ (1,156.4 )   $ (801.6 ) Cash, Cash Equivalents and Restricted Cash Our cash and cash equivalents are invested with highly rated financial institutions. Cash and cash equivalents include highly liquid investments with original maturities of three months or less. Due to the stability of our subscription model and consistency of annual, up-front billing, we aim to maintain a low cash balance. Cash balances are higher as of the end of Q3'26 than as of the end of Q4'25, which primarily reflects the timing of expected tax payments associated with the Kepware and ThingWorx divestiture. A significant portion of our cash is generated and held outside the U.S. As of June 30, 2026, we had cash and cash equivalents of $33 million in the U.S., $158 million in Europe, $144 million in Asia Pacific (including India) and $16 million in other countries. We have substantial cash requirements in the U.S. but believe that the combination of our existing U.S. cash and cash equivalents, cash available under our revolving credit facility, future U.S. operating cash inflows, and our ability to repatriate cash to the U.S. will be sufficient to meet our ongoing U.S. operating expenses and known capital requirements. Cash Provided by Operating Activities Cash provided by operating activities increased $88 million in the first nine months of FY'26 compared to the same period in FY'25. Growth was driven by higher collections and lower interest payments, partially offset by higher tax payments, higher payroll and related payments, and $24 million of divestiture-related payments. 28 Table of Contents     Cash Provided by (Used in) Investing Activities Cash provided by investing activities in the first nine months of FY'26 was driven by $523 million in consideration received for the divestiture of the Kepware and ThingWorx businesses, partially offset by a $50 million strategic solar energy investment. Cash Used in Financing Activities Cash used in financing activities in the first nine months of FY'26 was driven by $1,326 million of repurchases of common stock, partially offset by $225 million of net borrowings on our credit facility. Cash used in financing activities in the first nine months of FY'25 included net payments of $517 million on our outstanding debt, including the redemption of our 2025 senior notes primarily using a draw on our credit facility, and $225 million of repurchases of common stock.   Outstanding Debt (in millions)   June 30, 2026     September 30, 2025   4.000% Senior notes due 2028   $ 500.0     $ 500.0   Credit facility revolver line     475.0       231.3   Credit facility term loan     450.1       468.8   Total debt   $ 1,425.1     $ 1,200.0   Unamortized debt issuance costs for the senior notes     (1.8 )     (2.6 ) Total debt, net of issuance costs   $ 1,423.3     $ 1,197.4               Undrawn under credit facility revolver   $ 774.9     $ 1,018.8   Undrawn under credit facility revolver available to borrow   $ 757.5     $ 1,001.7   As of June 30, 2026, we were in compliance with all financial and operating covenants of the credit facility and the note indenture. As of June 30, 2026, the annual rate for borrowings outstanding under the credit facility was 5.0%. Our credit facility and our senior notes are described in Note 10. Debt to the Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q. As of June 30, 2026, $25 million of our debt associated with the credit facility term loan was classified as current. Share Repurchases Our Articles of Organization authorize us to issue up to 500 million shares of our common stock. Our Board of Directors has authorized us to repurchase up to $2 billion of our common stock in the period October 1, 2024 through September 30, 2026, and up to $2 billion of our common stock in the period October 1, 2026 through September 30, 2028. All shares of our common stock repurchased are automatically restored to the status of authorized and unissued. In Q2'26, we entered into an ASR to repurchase $375 million of our outstanding common stock as described in Note 4. Earnings per Share (EPS) and Common Stock . Final settlement of the ASR occurred in Q3'26. Future Expectations We believe that our existing cash and cash equivalents, together with cash generated from operations and amounts available under our credit facility, will be sufficient to meet our working capital, capital expenditure, and committed cash requirements for at least the next twelve months, as well as our known long-term capital requirements. 29 Table of Contents     Our expected uses and sources of cash could change, our cash position could be reduced, and we could incur additional debt obligations if we retire other debt, engage in strategic transactions, or repurchase shares, any of which could be commenced, suspended, or completed at any time. Any such repurchases or retirement of debt will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved in any debt retirement or issuance, share repurchases, or strategic transactions may be material. Operating and Non-GAAP Financial Measures Operating Measure ARR ARR (Annual Run Rate) represents the annualized value of our portfolio of active subscription software, SaaS, hosting, and support contracts as of the end of the reporting period. We calculate ARR as follows: • We consider a contract to be active when the product or service contractual term commences (the “start date”) until the right to use the product or service ends (the “expiration date”). Even if the contract with the customer is executed before the start date, the contract will not count toward ARR until the customer right to receive the benefit of the products or services has commenced. • For contracts that include annual values that change over time, we include in ARR only the annualized value of components of the contract that are considered active as of the date of the ARR calculation. We do not include any future committed increases in the contract value as of the date of the ARR calculation. • As ARR includes only contracts that are active at the end of the reporting period, ARR does not reflect assumptions or estimates regarding future contract renewals or non-renewals. • Active contracts are annualized by dividing the total active contract value by the contract duration in days (expiration date minus start date), then multiplying that by 365 days (or 366 days for leap years). We believe ARR is a valuable operating measure to assess the health of a subscription business because it is aligned with the amount that we invoice the customer on an annual basis. We generally invoice customers annually for the current year of the contract. A customer with a one-year contract will typically be invoiced for the total value of the contract at the beginning of the contractual term, while a customer with a multi-year contract will be invoiced for each annual period at the beginning of each year of the contract. ARR increases by the annualized value of active contracts that commence in a reporting period and decreases by the annualized value of contracts that expire in the reporting period. As ARR is not annualized recurring revenue, it is not calculated based on recognized or unearned revenue and is not affected by variability in the timing of revenue under ASC 606, particularly for on-premises license subscriptions where a substantial portion of the total value of the contract is recognized as revenue at a point in time upon the later of when the software is made available, or the subscription term commences. ARR should be viewed independently of recognized and unearned revenue and is not intended to be combined with, or to replace, either of those items. Investors should consider our ARR operating measure only in conjunction with our GAAP financial results. 30 Table of Contents     Non-GAAP Financial Measures Our non-GAAP financial measures and the reasons we use them and exclude the items identified below are described in Management's Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended September 30, 2025. The non-GAAP financial measures presented in the discussion of our results of operations and the respective most directly comparable GAAP measures are: • non-GAAP gross margin—GAAP gross margin • non-GAAP operating income—GAAP operating income • non-GAAP operating margin—GAAP operating margin • non-GAAP net income—GAAP net income • non-GAAP diluted earnings per share—GAAP diluted earnings per share • free cash flow—cash flow from operations The non-GAAP financial measures other than free cash flow exclude, as applicable: stock-based compensation expense; amortization of acquired intangible assets; acquisition and transaction-related charges included in General and administrative expenses; Impairment and other charges (credits), net; non-operating charges (credits), net; and income tax adjustments as defined in our Annual Report on Form 10-K for the fiscal year ended September 30, 2025 and as reflected in the reconciliation tables. The items excluded from the non-GAAP financial measures often have a material impact on our financial results, certain of those items are recurring, and other items often recur. Accordingly, the non-GAAP financial measures included in this Quarterly Report on Form 10-Q should be considered in addition to, and not as a substitute for or superior to, the comparable measures prepared in accordance with GAAP. The following tables reconcile each of these non-GAAP financial measures to the most closely comparable GAAP measure on our financial statements. 31 Table of Contents     (in millions, except per share amounts)   Three months ended     Nine months ended       June 30, 2026     June 30, 2025     June 30, 2026     June 30, 2025   GAAP gross margin   $ 490.5     $ 533.9     $ 1,719.2     $ 1,517.3   Stock-based compensation     5.6       5.3       18.7       16.7   Amortization of acquired intangible assets included in cost of revenue     7.8       8.2       23.4       24.6   Non-GAAP gross margin   $ 503.8     $ 547.4     $ 1,761.4     $ 1,558.7   GAAP operating income   $ 166.5     $ 209.8     $ 683.4     $ 548.8   Stock-based compensation     59.4       54.0       185.8       161.4   Amortization of acquired intangible assets     19.7       19.7       59.5       59.0   Acquisition and transaction-related charges     2.9       1.6       40.0       2.4   Impairment and other charges, net     —       —       —       4.2   Non-GAAP operating income   $ 248.5     $ 285.2     $ 968.8     $ 775.8   GAAP net income   $ 118.8     $ 141.3     $ 876.0     $ 386.2   Stock-based compensation     59.4       54.0       185.8       161.4   Amortization of acquired intangible assets     19.7       19.7       59.5       59.0   Acquisition and transaction-related charges     2.9       1.6       40.0       2.4   Impairment and other charges, net     —       —       —       4.2   Non-operating credits, net (1)     —       —       (463.9 )     —   Income tax adjustments (2)     (19.4 )     (19.3 )     33.9       (65.7 ) Non-GAAP net income   $ 181.4     $ 197.4     $ 731.5     $ 547.5   GAAP diluted earnings per share   $ 1.03     $ 1.17     $ 7.43     $ 3.20   Stock-based compensation     0.52       0.45       1.58       1.34   Amortization of acquired intangible assets     0.17       0.16       0.50       0.49   Acquisition and transaction-related charges     0.03       0.01       0.34       0.02   Impairment and other charges, net     —       —       —       0.03   Non-operating credits, net (1)     —       —       (3.94 )     —   Income tax adjustments (2)     (0.17 )     (0.16 )     0.29       (0.54 ) Non-GAAP diluted earnings per share   $ 1.58     $ 1.64     $ 6.21     $ 4.53                           Cash provided by operating activities   $ 260.6     $ 243.9     $ 851.3     $ 763.7   Capital expenditures     (11.3 )     (1.9 )     (16.3 )     (7.5 ) Free cash flow   $ 249.3     $ 242.0     $ 835.0     $ 756.2     (1) In Q2'26, we recognized gains of $462.6 million on the sale of the Kepware and ThingWorx businesses and $2.0 million related to the finalization of contingent consideration associated with the FY'22 sale of a portion of our PLM services business. In Q1'26, we recognized a $0.8 million financing charge related to a debt commitment agreement associated with our anticipated divestiture of the Kepware and ThingWorx businesses. (2) Income tax adjustments reflect the tax effects of non-GAAP adjustments which are calculated by applying the applicable tax rate by jurisdiction to the non-GAAP adjustments listed above. Additionally, in the first nine months of FY'25, adjustments exclude a $10.4 million benefit related to the tax impact of tax reserves related to prior years in foreign jurisdictions.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK There have been no significant changes in our market risk exposure as described in Item 7A. Quantitative and Qualitative Disclosures about Market Risk of our 2025 Annual Report on Form 10-K. ITEM 4. CONTROLS AN D PROCEDURES Evaluation of Effectiveness of Disclosure Controls and Procedures Our management 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”) that are designed to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), as appropriate, to allow for timely decisions regarding required disclosure. We evaluated, under the supervision and with the participation of management, including our principal executive and principal financial officers, the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this quarterly report. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2026. Changes in Internal Control over Financial Reporting There was no change in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act that occurred during the period ended June 30, 2026 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 33 Table of Contents     PART II—OTHE R INFORMATION ITEM 1A.
