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. The Company’s unique combination of product capabilities, deep domain expertise and award-winning innovation helps customers across diverse end markets in capital-intensive industries improve their operational excellence while achieving sustainability goals. The Company has revenue from customers in 117 countries as of December 31, 2023. Basis of Presentation The Company has prepared the accompanying unaudited condensed consolidated financial statements as of December 31, 2023, and for the second quarter 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 and combined 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 limited 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 revenue of approximately $5.8 million and $16.8 million for the three months ended December 31, 2023 and 2022, respectively, and $13.0 million and $26.8 million for the six months ended December 31, 2023 and 2022, respectively. The Company had total assets of approximately $35.2 million and $39.7 million as of December 31, 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. The Company has terminated all engineering services in Russia and the Company has limited its operations to contract renewals with existing customers. While the Company continues to evaluate the impact of the various sanctions and restrictions imposed by the United States and other governments on the Company ’ s ability to conduct business in Russia, 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 and assets 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 six months ended December 31, 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 prospective 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 and 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.

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 December 31, 2023. The Company’s contract assets and contract liabilities were as follows as of December 31, 2023 and June 30, 2023: December 31, 2023 June 30, 2023 (Dollars in Thousands) Contract assets $ 964,165 $ 903,643 Contract liabilities (170,558) (181,553) Net contract assets $ 793,607 $ 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 six months ended December 31, 2023 was primarily due to greater revenue recognition as compared to billings. Revenue recognized from the contract liability balance as of June 30, 2023, was $47.4 million and $88.4 million for the three and six months ended December 31, 2023, respectively. Transaction Price Allocated to Remaining Performance Obligations The following table includes the aggregate amount of the transaction price allocated as of December 31, 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 $ 104,615 $ 98,569 $ 45,664 $ 20,742 $ 6,911 $ 2,243 $ 278,744 Maintenance 165,061 257,890 192,502 134,883 85,101 44,596 880,033 Services and other 32,075 40,838 5,903 1,326 721 426 81,289 Total $ 301,751 $ 397,297 $ 244,069 $ 156,951 $ 92,733 $ 47,265 $ 1,240,066 Disaggregated Revenue Information The table below reflects disaggregated revenues by business for the three months and six months ended December 31, 2023 and 2022: Three Months Ended December 31, Six Months Ended December 31, 2023 2022 2023 2022 (Dollars in Thousands) Heritage AspenTech $ 167,437 $ 167,442 $ 343,180 $ 343,848 Subsurface Science & Engineering 28,574 29,726 52,655 62,714 OSI, Inc. 61,152 45,670 110,636 87,095 Total $ 257,163 $ 242,838 $ 506,471 $ 493,657

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 December 31, 2023 and June 30, 2023, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: December 31, 2023 Level 1 Inputs Level 2 Inputs (Dollars in Thousands) Cash equivalents $ 7,715 $ — Equity method investments $ — $ 2,398 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 10, “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. Amended and Restated Credit Agreement The Company has an Amended and Restated Credit Agreement (the “Amended and Restated Credit Agreement”) with JPMorgan Chase Bank, N.A. (“JPMorgan”) that provides for a $200.0 million secured revolving credit facility. As of December 31, 2023, after taking into account eligible outstanding letters of credit allowable per the Amended and Restated Credit Agreement in the aggregate amount of $2.6 million, the Company had $197.4 million available for borrowing under the Amended and Restated Credit Agreement.

The weighted average grant date fair value per performance stock unit was $199.06 and $194.03 during the three and six months ended December 31, 2023, respectively, and there were no granted or outstanding performance stock units during the three and six months ended December 31, 2022. Beginning in fiscal 2024, the Company granted performance stock units with a performance condition and service condition. These performance stock units vest on a cliff basis in three years based upon the achievement of predefined performance goals, with the ability for 25% of granted awards to vest on an accelerated basis in each of the first two years. The performance goal relates to the sum of (i) annual contract value growth and (ii) free cash flow margin over the performance period. Up to 175% of the performance stock units could vest upon achievement of the performance goals. Conversely, if a minimum performance goal is not met, none of the performance stock units will vest. On a quarterly basis, management evaluates the probability that the threshold performance goals will be achieved, if at all, and the anticipated level of attainment to determine the amount of compensation expense to record in the condensed consolidated financial statements.

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 and six months ended December 31, 2023 and 2022 are as follows: Three Months Ended December 31, Six Months Ended December 31, 2023 2022 2023 2022 (Dollars and Shares in Thousands, Except per Share Data) Net loss $ (21,500) $ (66,197) $ (56,025) $ (77,441) Basic weighted average shares outstanding 63,699 64,621 64,009 64,538 Dilutive weighted average shares outstanding 63,699 64,621 64,009 64,538 Net loss per share Basic $ (0.34) $ (1.02) $ (0.88) $ (1.20) Dilutive $ (0.34) $ (1.02) $ (0.88) $ (1.20) For the three and six months ended December 31, 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 December 31, 2023 and 2022: Three Months Ended December 31, Six Months Ended December 31, 2023 2022 2023 2022 (Shares in Thousands) Employee equity awards 1,433 1,574 1,352 1,479

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 an aggregate $300.0 million of its common stock may be repurchased, by means of open market transactions, block transactions, privately negotiated purchase transactions or any other purchase techniques, including 10b5-1 trading plans. The timing and amount of any shares repurchased under the Share Repurchase Authorization are based on market conditions and other factors. All shares of the Company’s common stock repurchased have been recorded as treasury stock under the cost method. The Company reflects share repurchases in its condensed consolidated financial statements once the transaction is settled.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Benefit) Provision 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, starting with the six months ended December 31, 2022, 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. For the three and six months ended December 31, 2023, the Company again recorded the actual effective tax rate as it was determined that the AETR approach was not the most appropriate estimate. Benefit for income taxes was $15.7 million for the three months ended December 31, 2023 and income tax expense was $49.6 million for the three months ended December 31, 2022, resulting in effective tax rates of 42.1% and (298.0)%, respectively. Income tax benefit primarily increased due to the prior year’s change in the Company’s approach to computing its tax provision (benefit) for interim periods to an actual effective tax rate method. Benefit for income taxes was $33.1 million and $44.0 million for the six months ended December 31, 2023 and 2022, respectively, resulting in effective tax rates of 37.2% and 36.2%, respectively. Income tax benefit decreased primarily due to an increase in year-to-date earnings and a reduced Foreign-Derived Intangible Income (“FDII”) deduction recorded in the current period.

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.

Leases [Abstract]
Lessee, Leases [Policy Text Block]	Leases On December 26, 2023, the Company entered into an amendment to its existing lease agreement at its principal executive offices located in Bedford, Massachusetts (the “Lease Amendment”). Under the Lease Amendment, the Company: (i) extended the term of the existing lease for approximately 132,000 rentable square feet from March 2025 to March 2038, and (ii) obtained an additional approximate 23,000 rentable square feet of office space, also through March 2038. The Company accounted for the Lease Amendment as a lease modification. Accordingly, the right-of-use assets and lease liabilities were remeasured using an incremental borrowing rate at the date of modification. This lease modification resulted in the recording of an additional right-of-use asset and lease liability of $32.9 million recognized on the condensed consolidated balance sheet, which is reflected net of a $25.4 million leasehold improvement incentive to be paid directly to external vendors by the landlord under the Lease Amendment. As invoices are paid by the landlord during construction of the improvements, the Company will increase the balances of the lease liability and construction-in-process assets, which is included within property, equipment and leasehold improvements, net in the condensed consolidated balance sheets.

Restricted Stock Units and Performance Stock Units Restricted stock units and performance stock units are not included in issued and outstanding common stock until the units are vested and the underlying shares are settled. The table below summarizes activities related to restricted stock units and performance stock units for the six months ended December 31, 2023: Number of Shares Underlying Restricted Units — Performance-Based Awards Number of Shares Underlying Restricted Units — Time-Based Awards (Dollars in Thousands) Outstanding as of June 30, 2023 — 456,368 Granted 94,174 186,938 Settled — (229,807) Cancelled / Forfeited (716) (12,792) Outstanding as of December 31, 2023 93,458 400,707 Weighted average remaining recognition period of outstanding restricted units (in years) 2.50 3.03 Unrecognized stock-based compensation expense of outstanding restricted units $ 8,824 $ 43,170 Aggregate intrinsic value of outstanding restricted units $ 14,418 $ 86,235 The weighted average grant date fair value per restricted stock unit was $192.21 and $246.15 during the three months ended December 31, 2023 and 2022, respectively, and $193.74 and $209.79 during the six months ended December 31, 2023 and 2022, respectively. The weighted average grant date fair value per performance stock unit was $199.06 and $194.03 during the three and six months ended December 31, 2023, respectively, and there were no granted or outstanding performance stock units during the three and six months ended December 31, 2022. Beginning in fiscal 2024, the Company granted performance stock units with a performance condition and service condition. These performance stock units vest on a cliff basis in three years based upon the achievement of predefined performance goals, with the ability for 25% of granted awards to vest on an accelerated basis in each of the first two years. The performance goal relates to the sum of (i) annual contract value growth and (ii) free cash flow margin over the performance period. Up to 175% of the performance stock units could vest upon achievement of the performance goals. Conversely, if a minimum performance goal is not met, none of the performance stock units will vest. On a quarterly basis, management evaluates the probability that the threshold performance goals will be achieved, if at all, and the anticipated level of attainment to determine the amount of compensation expense to record in the condensed consolidated financial statements.
