Nature of Operations		Organization and Basis of Presentation AspenTech, together with its subsidiaries (the “Company”), is a leading industrial software company that develops solutions to address complex industrial environments where it is critical to optimize the asset design, operations and maintenance lifecycle. Through the Company’s unique combination of product capabilities, deep domain expertise and award-winning innovation, customers across diverse end markets in capital-intensive industries can improve their operational excellence while achieving sustainability goals. The Company operates globally in 120 countries as of September 30, 2023. Basis of Presentation The Company has prepared the accompanying unaudited condensed consolidated financial statements as of September 30, 2023, and for the first quarters of fiscal 2024 and 2023 pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) and in accordance with generally accepted accounting principles in the United States (“GAAP”). All intercompany balances and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023. The preparation of financial statements and related disclosures in conformity with GAAP requires us to make judgments, assumptions, and estimates that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. The actual results that the Company experiences may differ materially from these estimates. Russia and Ukraine The Company maintains operations in Russia and licenses software and provides related services to customers in Russia and areas of Ukraine that are not under sanctio n. The Company had revenues of approximately $7.2 million and $10.0 million for the three months ended September 30, 2023 and 2022, respectively, and total assets of approximately $37.8 million and $39.7 million as of September 30, 2023 and June 30, 2023, respectively, related to operations in Russia. The Company may be required to cease or suspend operations in Russia or, should the conflict or the effects of sanctions, export control measures and business restrictions worsen, the Company may voluntarily elect to do so. For example, the Company recently has terminated all engineering services in Russia and the Company has limited its operations to contract renewals only with existing customers. While the Company continues to evaluate the impact, if any, of the various sanctions, export control measures and business restrictions imposed by the United States, other governments, and financial institutions on the ability to do business in Russia and areas of Ukraine that are not under sanction, maintain contracts with vendors and pay employees in Russia, and receive payment from customers in Russia and areas of Ukraine that are not under sanction, there is no assurance that the Company will be able to do so in the future. Any disruption to, or suspension of, the Company ’ s business and operations in Russia would result in the loss of revenue from the business in Russia and would negatively impact growth. The Company may also suffer reputational harm as a result of continued operations in Russia, which may adversely impact sales and other businesses in other countries.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Our significant accounting policies are described in Note 2 to the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023. There were no material changes to our significant accounting policies during the three months ended September 30, 2023. (a) Revenue Recognition Prior to the third quarter of fiscal 2023, Open Systems International, Inc. (“OSI Inc.”) software licenses were primarily sold with professional services and hardware to form an integrated solution for the customer. The professional services and hardware sold with the license significantly customized the underlying functionality and usability of the software. As such, none of the software license, hardware or professional services were considered distinct within the context of the contract and were therefore considered a single performance obligation. Because the integrated solution had no alternative use to the Company and the Company held an enforceable right to payment, revenue was recognized over time (typically one to two years) using an input measure of progress based on the ratio of actual costs incurred to date to the total estimated cost to complete. For integrated solution contracts executed prior to the third quarter of fiscal 2023, revenue continues to be recognized over time until the implementation is complete. At the start of the third quarter of fiscal 2023, the Company completed a series of business transformation activities relating to OSI Inc. products and services in conjunction with its ongoing integration activities. As part of a change in the related go-to-market strategy, the Company has invested in tools and processes to simplify and streamline the implementation services to significantly reduce the complexity and interdependency associated with its software. In addition, the Company has identified and trained several third-party implementation service partners to operate autonomously and directly with OSI Inc. customers to implement its products. Accordingly, effective January 1, 2023, following the completion of these business transformation activities, for all new OSI Inc. contracts entered into after January 1, 2023, the Company accounts for the OSI Inc. software license, hardware, maintenance, and professional services as separate and distinct performance obligations. Software license revenue is recognized at a point in time when control transfers to the customer, which generally aligns with the first day of the contractual term. Hardware revenue is recognized at the point in time when control transfers to the customer, which generally occurs upon delivery. The recognition of maintenance revenue at OSI Inc. is unchanged. Maintenance revenue continues to be recognized ratably over the maintenance term. Professional services revenue is recognized over time (typically one to two years) using the proportional performance method by comparing the costs incurred to the total estimated project costs. (b) Recently Issued Accounting Pronouncements Recently issued accounting pronouncements that will be applicable to the Company are not expected to have a material impact on the Company’s condensed consolidated financial statements.

Revenue from Contracts with Customers [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue from Contracts with Customers Contract Assets and Contract Liabilities Contract assets are subject to credit risk and reviewed in accordance with Accounting Standards Codification (“ASC”) 326, Financial Instruments Credit Losses . The Company monitors the credit quality of customer contract asset balances on an individual basis, at each reporting date, through credit characteristics, geographic location, and the industry in which they operate. The Company recognizes an impairment on contract assets if, subsequent to contract inception, it becomes probable payment is not collectible. An allowance for expected credit loss reflects losses expected over the remaining term of the contract asset and is determined based upon historical losses, customer-specific factors, and current economic conditions. The potential impact of credit losses on contract assets was immaterial as of September 30, 2023. The Company’s contract assets and contract liabilities were as follows as of September 30, 2023 and June 30, 2023: September 30, 2023 June 30, 2023 (Dollars in Thousands) Contract assets $ 916,636 $ 903,643 Contract liabilities (144,781) (181,553) Net contract assets $ 771,855 $ 722,090 The majority of the Company’s contract balances are related to arrangements where revenue is recognized at a point in time and payments are made according to a contractual billing schedule. The change in the net contract asset balance during the three months ended September 30, 2023 was primarily due to greater revenue recognition as compared to billings. Revenue recognized during the first quarter of fiscal 2024 included $41.0 million that was included in the beginning contract liability balance. Transaction Price Allocated to Remaining Performance Obligations The following table includes the aggregate amount of the transaction price allocated as of September 30, 2023 to the performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period: Year Ending June 30, 2024 2025 2026 2027 2028 Thereafter Total (Dollars in Thousands) License and solutions $ 108,987 $ 96,644 $ 42,092 $ 14,588 $ 2,396 $ 1,279 $ 265,986 Maintenance 223,670 223,635 164,342 114,089 69,953 33,105 828,794 Services and other 53,036 22,957 8,941 2,868 952 157 88,911 Total $ 385,693 $ 343,236 $ 215,375 $ 131,545 $ 73,301 $ 34,541 $ 1,183,691 Disaggregated Revenue Information The table below reflects disaggregated revenues by business for the three months ended September 30, 2023 and 2022: Three Months Ended September 30, 2023 2022 (Dollars in Thousands) Heritage AspenTech $ 175,743 $ 176,406 Subsurface Science & Engineering 24,081 32,988 OSI, Inc. 49,484 41,425 Total $ 249,308 $ 250,819

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The Company determines fair value by utilizing a fair value hierarchy that ranks the quality and reliability of the information used in its determination. Fair values determined using “Level 1 inputs” utilize unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined using “Level 2 inputs” utilize data points that are observable, such as quoted prices, interest rates and yield curves for similar assets and liabilities. Cash equivalents are reported at fair value utilizing quoted market prices in identical markets, or “Level 1 Inputs.” The Company’s cash equivalents consist of short-term money market instruments. Equity method investments are reported at fair value calculated in accordance with the market approach, utilizing market consensus pricing models with quoted prices that are directly or indirectly observable, or “Level 2 Inputs.” The following table summarizes financial assets and liabilities measured and recorded at fair value on a recurring basis in the accompanying condensed consolidated balance sheets as of September 30, 2023 and June 30, 2023, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: September 30, 2023 Level 1 Inputs Level 2 Inputs (Dollars in Thousands) Cash equivalents $ 29,264 $ — Equity method investments $ — $ 2,651 June 30, 2023 Level 1 Inputs Level 2 Inputs (Dollars in Thousands) Cash equivalents $ 132,918 $ — Equity method investments $ — $ 2,673 Financial instruments not measured or recorded at fair value in the accompanying condensed consolidated financial statements consist of accounts receivable, accounts payable and accrued liabilities. The estimated fair value of these financial instruments approximates their carrying value. The estimated fair value of the borrowings under the Amended and Restated Credit Agreement (described below in Note 8, “Debt”) approximates its carrying value due to the floating interest rate.

Debt Disclosure [Abstract]
Credit Agreement	Debt Credit Agreement with Related Party On December 23, 2022, the Company entered into a credit agreement with Emerson (the “Emerson Credit Agreement”), which provided for an aggregate term loan commitment of $630.0 million. Under the terms of the Emerson Credit Agreement, the Company would have used the proceeds from borrowings under the Emerson Credit Agreement to pay in part the cash consideration for funding the acquisition of Mining Software Holdings Pty Ltd (“Micromine”) and to pay the fees and expenses incurred in connection with the Emerson Credit Agreement. On August 18, 2023, the Emerson Credit Agreement was terminated in connection with the termination of the agreement to purchase Micromine. There was no amount outstanding under the Emerson Credit Agreement at the time it was terminated.

Earnings Per Share [Abstract]
Net Income Per Share	Net Loss Per Share Basic (loss) income per share is determined by dividing net (loss) income by the weighted average common shares outstanding during the period. Diluted (loss) income per share is determined by dividing net (loss) income by diluted weighted average shares outstanding during the period. Diluted weighted average shares reflect the dilutive effect, if any, of potential common shares. To the extent their effect is dilutive, employee equity awards and other commitments to be settled in common stock are included in the calculation of diluted net (loss) income per share based on the treasury stock method. The calculations of basic and diluted net loss per share and basic and dilutive weighted average shares outstanding for the three months ended September 30, 2023 and 2022 are as follows: Three Months Ended September 30, 2023 2022 (Dollars and Shares in Thousands, Except per Share Data) Net loss $ (34,525) $ (11,244) Basic weighted average shares outstanding 64,319 64,454 Dilutive weighted average shares outstanding 64,319 64,454 Loss per share Basic $ (0.54) $ (0.17) Dilutive $ (0.54) $ (0.17) For the three months ended September 30, 2023, and 2022 certain employee equity awards were anti-dilutive based on the treasury stock method. The following employee equity awards were excluded from the calculation of dilutive weighted average shares outstanding because their effect would be anti-dilutive as of September 30, 2023 and 2022: Three Months Ended September 30, 2023 2022 (Shares in Thousands) Employee equity awards 1,449 286

Equity [Abstract]
Treasury Stock	Stock Repurchases On May 5, 2023, the Company entered into an accelerated share repurchase program (“ASR Program”) with JPMorgan to repurchase an aggregate of $100.0 million of the Company’s common stock. Pursuant to the terms of the ASR Program, the Company made an initial payment to JPMorgan and received an initial delivery of 487,626 shares of the Company’s common stock, which represented approximately 80% of the total number of shares of the Company’s common stock expected to be purchased under the ASR Program. The ASR Program was settled on August 7, 2023, resulting in an additional delivery of 107,045 shares of the Company’s common stock. The Company repurchased in total 594,671 shares of common stock for $100.0 million as part of the ASR Program. The $100.0 million payment made to JPMorgan was recognized as a reduction to stockholders’ equity, consisting of an increase in treasury stock representing the value of the 594,671 shares received upon settlement, offset by an increase to additional-paid-in-capital for the value of the shares repurchased in excess of the $100.0 million payment. On August 1, 2023, the Company announced that its Board of Directors approved a share repurchase program (the “Share Repurchase Authorization”) pursuant to which $300.0 million of its common stock may be repurchased in the aggregate, by means of open market transactions, block transactions, privately negotiated purchase transactions or any other purchase techniques, including 10b5-1 trading plans.

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Benefit for Income Taxes The Company computes its tax provision (benefit) for interim periods by applying the estimated annual effective tax rate (“AETR”) to year-to-date income from operations and adjusting for discrete items arising in that quarter. However, if the Company is unable to make a reliable estimate of its AETR, then the actual effective tax rate for the year-to-date period may be the best estimate. For the three months ended September 30, 2022, the Company computed its tax provision (benefit) using the AETR approach. However, for the three months ended September 30, 2023, the Company recorded the actual effective tax rate as it was determined that the AETR approach was not the most appropriate estimate to be applied to the year-to-date pretax (loss) income given small changes in the forecast of pre-tax (loss) income would result in significant changes in the AETR. Benefit for income taxes was $17.5 million and $93.5 million for the three months ended September 30, 2023 and 2022, respectively, resulting in effective tax rates of 33.6% and 89.3%, respectively. Income tax benefit decreased due to a change in the Company’s approach to computing its tax provision (benefit) for interim periods to an actual effective tax rate method.

(“Heritage AspenTech”) to contribute the Emerson industrial software business (the “Industrial Software Business”), along with $6.014 billion in cash, to create AspenTech (the “Transaction”). The Industrial Software Business included OSI Inc. and the Geological Simulation Software business (“GSS”), which the Company has renamed as Subsurface Science & Engineering ("SSE"). The Transaction closed on May 16, 2022 (“Closing Date”). Emerson owned approximately 55% of AspenTech on a fully diluted basis as of September 30, 2023. The Company utilizes some aspects of Emerson ’ s centralized treasury function to manage the working capital and financing needs of its business operations. This function oversees a cash pooling arrangement which sweeps certain Company cash accounts into pooled Emerson cash accounts on a daily basis. Pooled cash and nontrade balances attributable to Emerson have been presented as receivables from related parties or due to related parties in the condensed consolidated financial statements of the Company. Before the closing of the Transaction, the Industrial Software Business was charged for costs directly attributable to the SSE business and OSI Inc. and was allocated a portion of Emerson’s costs, including general corporate costs, information technology costs, insurance and other benefit costs, and shared service and other costs. All of these costs are reflected in the Company’s condensed consolidated financial statements. Management believes the methodologies and assumptions used to allocate these costs are reasonable. At the closing of the Transaction, Emerson and the Company entered into a transition service agreement (the “Transition Service Agreement”) for the provision of certain transitionary services from Emerson to the Company.

Before the closing of the Transaction, OSI Inc. and the SSE business engaged in various transactions to sell software and purchase goods in the ordinary course of business with affiliates of Emerson. At the closing, the Company and Emerson entered into a commercial agreement to allow Emerson to distribute software and services from the Company (the “Commercial Agreement”). Pursuant to the Commercial Agreement as amended from time to time in accordance with the Stockholders Agreement (as defined below), AspenTech grants Emerson the right to distribute, on a non-exclusive basis, certain (i) existing Heritage AspenTech products, (ii) existing Emerson products transferred to AspenTech pursuant to the Transaction Agreement and (iii) future AspenTech products as mutually agreed upon, in each case, to end-users through Emerson acting as an agent, reseller or original equipment manufacturer. Commercial Agreement-related activities have been recorded as revenues and expenses from related parties and resulting trade balances have been presented as trade receivables from related parties in the condensed consolidated financial statements presented. Revenue and purchases from Emerson affiliates for the three months ended September 30, 2023 and 2022 are as follows: Three Months Ended September 30, 2023 2022 (Dollars in Thousands) Revenue from Emerson affiliates $ 313 $ 4 Purchases from Emerson affiliates $ 68 $ 139 Emerson Share Maintenance Rights Immediately following the closing of the Transaction, Emerson beneficially owned 55% of the fully diluted shares of AspenTech common stock. At the Closing Date, the Company and Emerson entered into a stockholders agreement (the “Stockholders Agreement”), which sets forth, among other matters, the right of Emerson to nominate directors to the Company's board of directors, the right of Emerson to nominate the chair of the Company's board of directors, the composition of the committees of the Company's board of directors, certain consent rights of Emerson to certain material actions taken by the Company and consent rights with respect to modifications or changes to the Company's business strategy. Under the Stockholders Agreement, Emerson also has the right to acquire additional equity securities of AspenTech pursuant to pre-agreed procedures and rights in order to maintain its 55% ownership interest. No additional shares of common stock, or any other equity securities of AspenTech, were issued by the Company to Emerson subsequent to the closing of the Transaction through September 30, 2023.
