| Description of Business and Basis of Presentation | 1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION DESCRIPTION OF BUSINESS Neogen Corporation and subsidiaries ("Neogen," "we," "our" or the "Company") develop, manufacture and market a diverse line of products and services dedicated to food and animal safety. Our Food Safety segment consists primarily of diagnostic test kits and complementary products (e.g., culture media) sold to food producers and processors to detect dangerous and/or unintended substances in human food and animal feed, such as foodborne pathogens, spoilage organisms, natural toxins, food allergens, genetic modifications, ruminant by-products, meat speciation, drug residues, pesticide residues and general sanitation concerns. The majority of the test kits are disposable, single-use, immunoassay and DNA detection products that rely on proprietary antibodies and RNA and DNA testing methodologies to produce rapid and accurate test results. Our expanding line of food safety products also includes advanced software systems that help testers objectively analyze and store, as well as perform analysis on their results from multiple locations over extended periods. Neogen’s Animal Safety segment is engaged in the development, manufacture, marketing and distribution of veterinary instruments, pharmaceuticals, vaccines, topicals, parasiticides, diagnostic products, biosecurity products and genomics testing services for the worldwide animal safety market. The majority of these consumable products are marketed through veterinarians, retailers, livestock producers and animal health product distributors. Our line of drug detection products is sold worldwide for the detection of abused and therapeutic drugs in animals and animal products, and has expanded into the workplace and human forensic markets. BASIS OF PRESENTATION AND CONSOLIDATION The accompanying unaudited condensed consolidated financial statements include the accounts of Neogen and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (generally accepted accounting principles) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In our opinion, all adjustments considered necessary for a fair statement of the results of the interim period have been included in the accompanying unaudited condensed consolidated financial statements. All intercompany balances and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2025. New Accounting Pronouncements Adopted Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which modifies the disclosure and presentation requirements of reportable segments. The amendments in the update require the disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit and loss. The amendments also require disclosure of all other segment items by reportable segment and a description of its composition. Additionally, the amendments require disclosure of the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. We adopted this pronouncement and provided required interim disclosures in Note 5 "Segment Information and Geographic Data" to the condensed consolidated financial statements. We adopted the interim requirements on June 1, 2025.
Income Taxes (Topic 740): Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands disclosures in an entity’s income tax rate reconciliation table and disclosures regarding cash taxes paid both in the U.S. and foreign jurisdictions. This guidance becomes effective for our fiscal year 2026 annual reporting. We adopted this guidance effective June 1, 2025. New Accounting Pronouncements Not Yet Adopted Income Statement (Topic 220): Expense Disaggregation Disclosures In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures, which requires a public business entity to provide disaggregated disclosures, in the notes to the financial statements, of certain categories of expenses that are included in expense line items on the face of the income statement. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. We are currently evaluating the impact that the new guidance will have on the presentation of our consolidated financial statements and accompanying notes. Financial Instruments — Credit Losses (Topic 326): Measurement 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. The amendments provide a practical expedient and, if applicable, an accounting policy election to simplify the measurement of credit losses for certain receivables and contract assets. The amendments are effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted in any interim or annual period in which financial statements have not yet been issued or made available for issuance. We are currently evaluating the impact of this amendment and do not expect that the adoption of this guidance will have a material impact on our consolidated financial statements and accompanying notes. Interim Reporting (Topic 270): Narrow-Scope Improvements In December 2025, the FASB issued ASU 2025-11 to amend the guidance in “Interim Reporting” (Topic 270). The update provides clarifications intended to improve the consistency and usability of interim disclosure requirements, including a comprehensive listing of required interim disclosures and a new disclosure principle for reporting material events occurring after the most recent annual period. The amendments do not change the underlying objectives of interim reporting but are designed to enhance clarity in application. The guidance is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. We are currently evaluating the impact that the new guidance will have on the presentation of our consolidated financial statements and accompanying notes. |

| Assets Held for Sale and Divestiture | 3. ASSETS HELD FOR SALE AND DIVESTITURE
In June 2025, the Company announced plans to sell its global genomics business as part of an initiative to divest non-core assets. The genomics business and associated assets and liabilities met the criteria for presentation as held for sale as of November 30, 2025. The Company determined that fair value less cost to sell exceeded the carrying value. Therefore, no impairment charge was recognized. The planned divestiture did not meet the criteria for presentation as a discontinued operation.
The major classes of assets and liabilities held for sale of the Genomics business were as follows:
Cleaners and Disinfectants In April 2025, we announced that we had entered into a definitive agreement to sell our Cleaners and Disinfectants ("C&D") business to Kersia Group ("Kersia"). The planned divestiture did not meet the criteria for classification as a discontinued operation under ASC 205-20, as the sale does not represent a strategic shift that has or will have a major effect on our operations or financial results. In the first quarter of fiscal year 2026, we completed the sale of the C&D business to Kersia. We received total consideration of $121,724 in cash at closing, net of cash divested, plus additional contingent consideration of up to $3,500 (the “Earnout Payment”) based on revenue performance of the divested business during the 12-month period following the closing date. The Earnout Payment is subject to reduction if certain revenue thresholds, as defined in the purchase agreement, are not achieved. During the three months ended August 31, 2025, we recognized a gain on the sale of the business of $76,390, which is included in “Gain on sale of business” within the Consolidated Statements of Operations. In addition, at closing, we also entered into transition service and transition distribution agreements with Kersia, which require us to provide services to Kersia during the transition period. Related to the transition distribution agreements, for performance obligations for which we act as an agent, we record revenue as the net amount of our gross billings less amounts remitted to Kersia. For performance obligations for which we act as principal, we record the gross amount billed to the customer as revenue. We recorded a liability representing the fair value of the services we expect to provide of $1,691 within other current liabilities related to these agreements, which will be expensed to Other, net over a 12-month period following the closing date. |

| Net (Loss) Income Per Share | 4. NET (LOSS) INCOME PER SHARE Basic net (loss) income per share is computed by dividing net (loss) income by the weighted average number of shares of common stock outstanding during the period. Diluted net (loss) income per share is computed using the treasury stock method by dividing net (loss) income by the weighted average number of shares of common stock outstanding. The calculation of net (loss) income per share follows:
Due to the net loss reported for the three months ended November 30, 2025, the dilutive stock options and RSUs were anti-dilutive. For the six months ended November 30, 2025, 3,064,670 shares were excluded from the calculation of diluted net income per share, because the inclusion of such securities in the calculation would have been anti-dilutive. Due to the net loss reported for the three and six months ended November 30, 2024, the dilutive stock options and RSUs were anti-dilutive. |

| Goodwill | 6. GOODWILL
In the second quarter of fiscal year 2025, the Company identified that the impact of integration challenges and end market conditions on the recent overall financial performance of the Food Safety reporting unit represented a triggering event to test goodwill within that reporting unit for impairment as of September 1, 2024. Management utilized a third-party to quantitatively assess its Food Safety reporting unit. Fair value of the reporting unit was estimated based on a combination of an income-based approach, consisting of a discounted cash flows analysis, and a market-based approach, consisting of pricing multiples derived from an analysis of comparable public companies multiplied against historical and/or anticipated financial metrics of the reporting unit. The inputs to the fair value are defined in the fair value hierarchy as Level 3 inputs. Based on the results of the analysis, the carrying value of the Food Safety reporting unit exceeded its fair value as of September 1, 2024. Accordingly, an impairment charge of $461,390 was recorded in the second quarter of fiscal year 2025. Differences in the balance sheet change and impairment charge are due to foreign exchange. There were no goodwill impairment charges recorded in the second quarter of fiscal year 2026. |

| Restructuring | 7. RESTRUCTURING We regularly evaluate our business to ensure that we are properly configured and sized based on changing market conditions. Accordingly, we have implemented certain restructuring initiatives, including consolidation of certain facilities throughout the world and rationalization of our operations. In the second quarter of fiscal year 2026, management initiated a restructuring plan to right-size our cost base through a reduction of approximately 10% in global headcount, including both existing and planned positions, as well as additional non-labor cost reductions. In the second quarter of fiscal year 2025, management initiated a restructuring plan primarily designed to focus the end market exposure and streamline the operations of the Company's global genomics business. Our restructuring charges consist of severance payments, costs for outplacement services, and post-employment benefits (collectively, “employee separation costs”), other related exit costs and asset impairment charges related to restructuring activities. These amounts are partially recorded within sales and marketing and general and administrative expense on the consolidated statements of operations. Restructuring charges by segment were as follows:

During the three months ended August 31, 2025, we used the net proceeds from the Cleaners & Disinfectants divestiture to repay a portion of our outstanding debt. We repaid $51,500 of principal on the Revolving Facility, made $45,000 of prepayments on the Term Loan, and repurchased $3,500 of Senior Notes on the open market. The Term Loan prepayments resulted in an extinguishment loss of $393 related to unamortized debt issuance costs, while the Senior Notes repurchase resulted in an extinguishment loss of $41 related to unamortized debt issuance costs. |

| Income Taxes | 9. INCOME TAXES Income tax benefit was $4,440 and income tax expense was $3,030 during the three and six months ended November 30, 2025 compared to income tax benefit of $20,290 and $23,290 during the three and six months ended November 30, 2024, respectively. The net tax benefit for the quarter-to-date period was primarily related to pre-tax losses due to acquisition amortization and interest expense. The net tax expense for the year-to-date period was primarily related to pre-tax income due to gains on the sale of our Cleaners & Disinfectants business. The Organization for Economic Cooperation and Development (“OECD”) Pillar Two global minimum tax rules, which generally provide for a minimum effective tax rate of 15%, are intended to apply for tax years beginning in 2024. The Company continues to closely monitor developments and evaluate the impact these new rules will have on its tax rate, including eligibility to qualify for certain safe harbors. Where no safe harbor is met, the Company has included in its income tax for the three and six months ended November 30, 2025, a forecasted amount of “top-up” tax for its foreign subsidiaries as required under the applicable rules of the countries that have adopted the Pillar Two directives. For the three and six months ended November 30, 2025, no foreign subsidiary is forecasted to incur a material top-up tax under Pillar Two.
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into law in the United States. OBBBA includes significant provisions, including the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for depreciation and interest expenses. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. There was not a significant impact to our income tax expense or effective tax rate for the three and six months ended November 30, 2025. The total amounts of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of November 30, 2025 and May 31, 2025 were $5,232 and $3,849, respectively. Increases in unrecognized tax benefits are primarily associated with the acquired 3M FSD, including positions for transfer pricing and research and development credits. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies | 10. COMMITMENTS AND CONTINGENCIES We are involved in environmental remediation and monitoring activities at our Randolph, Wisconsin manufacturing facility. As a result, we accrue for related costs, when such costs are determined to be probable and estimable. We currently utilize a pump and treat remediation strategy, which includes semi-annual monitoring and reporting, consulting, and maintenance of monitoring wells. We recorded $100 within and $816 within as of November 30, 2025 and May 31, 2025 in the condensed consolidated balance sheets. These amounts are measured on an undiscounted basis over an estimated period of 15 years. In fiscal 2022, in collaboration with the WDNR, we initiated an in-situ chemical remediation pilot study, which ran over a two-year period. The results of this study were submitted to the WDNR as part of our standard annual report. If the WDNR were to require a change from the current pump and treat remediation strategy, this change could result in an increase in future costs and, ultimately, an increase in the currently recorded liability, with an offsetting charge to operations in the period recorded. Shareholder Litigation and Stockholder Demands On July 18, 2025, Operating Engineers Construction Industry and Miscellaneous Pension Fund filed a putative class action complaint in the United States District Court for the Western District of Michigan against the Company, John Adent, and David Naemura. The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 based on allegedly false and misleading public statements and omissions by defendants during the period January 5, 2023 through June 3, 2025 relating to the integration of the 3M business into Neogen. The complaint seeks, among other things, unspecified monetary damages, reasonable costs and expenses and/or other relief as deemed appropriate by the Court. Defendants have not yet responded to the complaint. On August 27, 2025, the Company, John Adent, Steven J. Quinlan, James C. Borel, William T. Boehm, Ronald D. Green, Ralph A. Rodriguez, James P. Tobin, Darci L. Vetter, and Catherine E. Woteki were named in a putative class action filed in Minnesota’s Second Judicial District for Ramsey County. The complaint asserts claims under Sections 11, 12(a)(2), and 15 of the Securities Act of 1933 based on allegedly false and misleading public statements by defendants in the offering materials issued in connection with the 2022 transaction in which Neogen acquired 3M’s Food Safety Business. The complaint seeks, among other things, unspecified monetary damages, reasonable costs and expenses, recission, and/or such other equitable or injunctive relief as deemed appropriate by the Court. Defendants have not yet responded to the complaint. On August 13, 2025, August 15, 2025, and December 22, 2025, the Company received three separate stockholder litigation demands requesting that the Board investigate the allegations in the Federal Action and pursue claims on the Company’s behalf based on those allegations. On October 4, 2025, the Board established a litigation committee to consider and investigate the demands. On December 4, 2025, the Company, John Adent, Dave Naemura, James C. Borel, Thierry Bernard, William T. Boehm, Jeffrey D. Capello, Ronald D. Green, Aashima Gupta, Raphael A. Rodriguez, James P. Tobin, Darci L. Vetter, and Catherine Woteki were named in a putative shareholder derivative action filed in the United States District Court for the Western District of Michigan. The complaint asserts claims under Section 14 of the Securities Exchange Act of 1934 and Michigan corporate law based on allegedly false and misleading public statements by defendants and alleged breaches of fiduciary duties related to the integration of the 3M business into Neogen. The complaint seeks, among other things, unspecified monetary damages, reasonable costs and expenses, rescission, and/or such other equitable or injunctive relief as deemed appropriate by the Court. Defendants have not yet filed a responsive pleading in this action. The Company intends to vigorously defend the matters. Given the uncertainty of litigation and the preliminary stage of the cases, we cannot estimate the reasonably possible loss or range of loss that may result from the actions. Other than the shareholder items noted above, we are subject to certain legal and other proceedings that, in the opinion of management, are not expected to have a material effect on our financial statements. |

| Derivative Instruments and Hedging Activities Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Derivatives and Fair Value | 11. DERIVATIVES AND FAIR VALUE Derivatives We operate globally and are exposed to market risks arising from fluctuations in foreign currency exchange rates and interest rates. As part of our financial risk management strategy, we use derivative financial instruments to hedge exposure to variability in cash flows associated with these market risks. These instruments are used solely for risk management purposes; We do not engage in derivative transactions for trading or speculative purposes. Derivatives Not Designated as Hedging Instruments We have entered into non-designated foreign currency forward contracts to manage foreign currency balance sheet risk associated with intercompany loans and other foreign currency denominated assets and liabilities. These contracts are recorded net at fair value on our consolidated balance sheets, classified as Level 2 in the fair value hierarchy. The notional amount of forward contracts in place was $50,418 and $65,023 as of November 30, 2025 and May 31, 2025, respectively, and consisted of economic hedges of transactions up to January 2026.
The location and amount of losses from derivatives not designated as hedging instruments in our condensed consolidated statements of operations were as follows:
Derivatives Designated as Hedging Instruments In November 2022, we entered into a receive-variable, pay-fixed interest rate swap agreement with a $250,000 notional value, which is designated as a cash flow hedge. In accordance with the agreement, the notional value decreased to $200,000 in November 2024. This agreement fixed a portion of the variable interest due on our term loan facility, with an effective date of December 2, 2022 and a maturity date of June 30, 2027. Under the terms of the agreement, we pay a fixed interest rate of 4.215%, plus an applicable margin ranging between 137.5 to 175 basis points and receive a variable rate of interest based on term SOFR from the counterparty, which is reset according to the duration of the SOFR term. We expect to reclassify a $950 loss of accumulated other comprehensive income into earnings in the next 12 months. We record the fair value of our interest rate swaps on a recurring basis using Level 2 observable market inputs for similar assets or liabilities in active markets.
Fair Value of Financial Instruments Fair value measurements are determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs. We utilize a fair value hierarchy based upon the observability of inputs used in valuation techniques as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The carrying amounts of our financial instruments other than cash equivalents and marketable securities, which include accounts receivable and accounts payable, approximate fair value based on either their short maturity or current terms for similar instruments. |

| Accounting Policies [Abstract] | |
| Basis of Presentation and Consolidation | BASIS OF PRESENTATION AND CONSOLIDATION The accompanying unaudited condensed consolidated financial statements include the accounts of Neogen and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (generally accepted accounting principles) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In our opinion, all adjustments considered necessary for a fair statement of the results of the interim period have been included in the accompanying unaudited condensed consolidated financial statements. All intercompany balances and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2025. |
| New Accounting Pronouncements Adopted | New Accounting Pronouncements Adopted Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which modifies the disclosure and presentation requirements of reportable segments. The amendments in the update require the disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit and loss. The amendments also require disclosure of all other segment items by reportable segment and a description of its composition. Additionally, the amendments require disclosure of the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. We adopted this pronouncement and provided required interim disclosures in Note 5 "Segment Information and Geographic Data" to the condensed consolidated financial statements. We adopted the interim requirements on June 1, 2025.
Income Taxes (Topic 740): Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands disclosures in an entity’s income tax rate reconciliation table and disclosures regarding cash taxes paid both in the U.S. and foreign jurisdictions. This guidance becomes effective for our fiscal year 2026 annual reporting. We adopted this guidance effective June 1, 2025. |
| New Accounting Pronouncements Not Yet Adopted | New Accounting Pronouncements Not Yet Adopted Income Statement (Topic 220): Expense Disaggregation Disclosures In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures, which requires a public business entity to provide disaggregated disclosures, in the notes to the financial statements, of certain categories of expenses that are included in expense line items on the face of the income statement. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. We are currently evaluating the impact that the new guidance will have on the presentation of our consolidated financial statements and accompanying notes. Financial Instruments — Credit Losses (Topic 326): Measurement 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. The amendments provide a practical expedient and, if applicable, an accounting policy election to simplify the measurement of credit losses for certain receivables and contract assets. The amendments are effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted in any interim or annual period in which financial statements have not yet been issued or made available for issuance. We are currently evaluating the impact of this amendment and do not expect that the adoption of this guidance will have a material impact on our consolidated financial statements and accompanying notes. Interim Reporting (Topic 270): Narrow-Scope Improvements In December 2025, the FASB issued ASU 2025-11 to amend the guidance in “Interim Reporting” (Topic 270). The update provides clarifications intended to improve the consistency and usability of interim disclosure requirements, including a comprehensive listing of required interim disclosures and a new disclosure principle for reporting material events occurring after the most recent annual period. The amendments do not change the underlying objectives of interim reporting but are designed to enhance clarity in application. The guidance is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. We are currently evaluating the impact that the new guidance will have on the presentation of our consolidated financial statements and accompanying notes. |
