Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION About Griffon Corporation Griffon Corporation (the “Company”, “Griffon”, "we" or "us") is a diversified management and holding company that conducts business through wholly-owned subsidiaries. Griffon oversees the operations of its subsidiaries, allocates resources among them and manages their capital structures. Griffon provides direction and assistance to its subsidiaries in connection with acquisition and growth opportunities, as well as in connection with divestitures. In order to further diversify, Griffon also seeks out, evaluates and, when appropriate, will acquire additional businesses that offer potentially attractive returns on capital. The Company was founded in 1959, is a Delaware corporation headquartered in New York, N.Y. and is listed on the New York Stock Exchange (NYSE:GFF). Griffon conducts its operations through two reportable segments: • Home and Building Products ("HBP") conducts its operations through Clopay Corporation ("Clopay"). Founded in 1964, Clopay is the largest manufacturer and marketer of garage doors and rolling steel doors in North America. Residential and commercial sectional garage doors are sold through professional dealers and leading home center retail chains throughout North America under the brands Clopay, Ideal, and Holmes. Rolling steel door and grille products designed for commercial, industrial, institutional, and retail use are sold under the Cornell and Cookson brands. • Consumer and Professional Products (“CPP”) is a leading global provider of branded consumer and professional tools; residential, industrial and commercial fans; home storage and organization products; and products that enhance indoor and outdoor lifestyles. CPP sells products globally through a portfolio of leading brands including AMES, since 1774, Hunter, since 1886, True Temper, and ClosetMaid. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information, and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all the information and footnotes required by US GAAP for complete financial statements. As such, they should be read together with Griffon’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023, which provides a more complete explanation of Griffon’s accounting policies, financial position, operating results, business, properties and other matters. In the opinion of management, these financial statements reflect all adjustments considered necessary for a fair statement of interim results. Griffon’s businesses are seasonal; for this and other reasons, the financial results of the Company for any interim period are not necessarily indicative of the results for the full year. The condensed consolidated balance sheet information at September 30, 2023 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2023. The condensed consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Certain amounts in prior years may have been reclassified to conform to the current year presentation. The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. These estimates may be adjusted due to changes in economic, industry or customer financial conditions, as well as changes in technology or demand. Significant estimates include expected loss allowances for credit losses and returns, net realizable value of inventories, restructuring reserves, valuation of goodwill and intangible assets, assumptions associated with pension benefit obligations and income or expenses, useful lives associated with depreciation and amortization of intangible and fixed assets, warranty reserves, sales incentive accruals, assumption associated with stock based compensation valuation, income taxes and tax valuation reserves, environmental reserves, legal reserves, insurance reserves, the valuation of assets and liabilities of discontinued operations and the accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions Griffon may undertake in the future. Actual results may ultimately differ from these estimates.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended
	Mar. 31, 2024
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The carrying values of cash and equivalents, accounts receivable, accounts and notes payable, and revolving credit and variable interest rate debt approximate fair value due to either the short-term nature of such instruments or the fact that the interest rate of the revolving credit and variable rate debt is based upon current market rates. Applicable accounting guidance establishes a fair value hierarchy requiring the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The accounting guidance establishes three levels of inputs that may be used to measure fair value, as follows: • Level 1 inputs are measured and recorded at fair value based upon quoted prices in active markets for identical assets. • Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities. • Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. On March 31, 2024, the fair values of Griffon’s 2028 Senior Notes and Term Loan B facility approximated $950,406 and $459,574, respectively. Fair values were based upon quoted market prices (level 1 inputs). Insurance contracts with values of $4,671 at March 31, 2024 are measured and recorded at fair value based upon quoted prices in active markets for similar assets (level 2 inputs) and are included in Prepaid and other current assets and $634 is included in other assets on the Consolidated Balance Sheets. Items Measured at Fair Value on a Recurring Basis In the normal course of business, Griffon’s operations are exposed to the effects of changes in foreign currency exchange rates related to inventory purchases. To manage these risks, Griffon may enter into various derivative contracts such as foreign currency exchange contracts, including forwards and options. As of March 31, 2024, Griffon entered into several such contracts in order to lock into a foreign currency rate for planned settlements of trade liabilities payable in U.S. dollars. At March 31, 2024, Griffon had $38,500 of Australian dollar contracts at a weighted average rate of $1.48 which qualified for hedge accounting (level 2 inputs). These hedges were all deemed effective as cash flow hedges with gains and losses related to changes in fair value deferred and recorded in Accumulated other comprehensive income (loss) ("AOCI") and Prepaid and other current assets, or Accrued liabilities, until settlement. Upon settlement, gains and losses are recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) in Cost of goods and services ("COGS"). AOCI included deferred gains of $1,388 ($972, net of tax) at March 31, 2024. Upon settlement, losses of $215 and gains of $310 were recorded in COGS during the three months and six months ended March 31, 2024. All contracts expire in 30 to 150 days. At March 31, 2024, Griffon had $49,500 of Chinese Yuan contracts at a weighted average rate of $6.93 which qualified for hedge accounting (level 2 inputs). These hedges were all deemed effective as cash flow hedges with gains and losses related to changes in fair value deferred and recorded in AOCI and Prepaid and other current assets, or Accrued liabilities, until settlement. Upon settlement, gains and losses are recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) in COGS. AOCI included deferred losses of $925 ($675, net of tax) at March 31, 2024. Upon settlement, losses of $564 and $1,200 were recorded in COGS during the three months and six months ended March 31, 2024. All contracts expire in 3 to 365 days.

REVENUE

REVENUE	6 Months Ended
	Mar. 31, 2024
Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service, or a bundle of goods or services, to the customer, and is the unit of accounting. A contract with a customer is an agreement which both parties have approved, that creates enforceable rights and obligations, has commercial substance and with respect to which payment terms are identified and collectability is probable. Once the Company has entered into a contract or purchase order, it is evaluated to identify performance obligations. For each performance obligation, revenue is recognized when control of the promised products is transferred to the customer, or services are satisfied under the contract or purchase order, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products or services (the transaction price). The Company’s performance obligations are recognized at a point in time related to the manufacture and sale of a broad range of products and components, and revenue is recognized when title, and risk and rewards of ownership, have transferred to the customer, which is generally upon shipment. For a complete explanation of Griffon’s revenue accounting policies, this note should be read in conjunction with Griffon’s Annual Report on Form 10-K for the year ended September 30, 2023.

Credit Loss [Abstract]
CREDIT LOSSES	CREDIT LOSSES The Company is exposed to credit losses primarily through sales of products and services. Trade receivables are recorded at their stated amount, less allowances for discounts, credit losses and returns. The Company’s expected loss allowance methodology for trade receivables is primarily based on the aging method of the accounts receivables balances and the financial condition of its customers. The allowances represent estimated uncollectible receivables associated with potential customer defaults on contractual obligations (usually due to customers’ potential insolvency), discounts related to early payment of accounts receivables by customers and estimates for returns. The allowance for credit losses includes amounts for certain customers in which a risk of default has been specifically identified, as well as an amount for customer defaults, based on a formula, when it is determined the risk of some default is probable and estimable, but cannot yet be associated with specific customers. Allowance for discounts and returns are recorded as a reduction of revenue and the provision related to the allowance for credit losses is recorded in SG&A expenses. The Company also considers current and expected future economic and market conditions when determining any estimate of credit losses. Generally, estimates used to determine the allowance are based on assessment of anticipated payment and all other historical, current and future information that is reasonably available. All accounts receivable amounts are expected to be collected in less than one year. Based on a review of the Company's policies and procedures across all segments, including the aging of its trade receivables, recent write-off history and other factors related to future macroeconomic conditions, Griffon determined that its method to determine credit losses and the amount of its allowances for bad debts is in accordance with the accounting guidance for credit losses on financial instruments, including trade receivables, in all material respects. The following table provides a roll-forward of the allowance for doubtful accounts, including provisions for expected credit losses that is deducted from gross accounts receivable to present the net amount expected to be collected: Six months ended March 31, 2024 2023 Beginning Balance, October 1 $ 11,264 $ 12,137 Provision for expected credit losses 904 2,395 Amounts written off charged against the allowance (636) (723) Other, primarily foreign currency translation 35 (554) Ending Balance, March 31 $ 11,567 $ 13,255

Proceeds from the 2028 Senior Notes were used to redeem $1,000,000 of 5.25% Senior Notes due 2022. In connection with the issuance and exchange of the 2028 Senior Notes, Griffon capitalized $16,448 of underwriting fees and other expenses incurred, which is being amortized over the term of such notes. During 2022, Griffon purchased $25,225 of 2028 Senior Notes in the open market at a weighted average discount of 91.82% of par, or $23,161. As of March 31, 2024, outstanding 2028 Senior Notes due totaled $974,775; interest is payable semi-annually on March 1 and September 1. The 2028 Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. The 2028 Senior Notes were registered under the Securities Act of 1933, as amended (the "Securities Act") via exchange offer. The fair value of the 2028 Senior Notes approximated $950,406 on March 31, 2024 based upon quoted market prices (level 1 inputs). At March 31, 2024, $7,910 of underwriting fees and other expenses incurred remained to be amortized. (b) On August 1, 2023, Griffon amended and restated its Credit Agreement (as amended, "Credit Agreement"). The amendment increased the maximum borrowing availability on its revolving credit facility from $400,000 to $500,000 (the "Revolver") and extended the maturity date of the Revolver from March 22, 2025 to August 1, 2028. In the event the 2028 Senior Notes are not repaid, refinanced, or replaced prior to December 1, 2027, the Revolver will mature on December 1, 2027. The amendment also modified certain other provisions of the Credit Agreement, including increasing the letter of credit sub-facility under the Revolver from $100,000 to $125,000 and increasing the customary accordion feature from a minimum of $375,000 to a minimum of $500,000. The Revolver also includes a multi-currency sub-facility of $200,000. Borrowings under the Revolver may be repaid and re-borrowed at any time. Interest is payable on borrowings at either a Secured Overnight Financing Rate ("SOFR"), Sterling Overnight Index Average ("SONIA") or base rate benchmark rate, plus an applicable margin, which adjusts based on financial performance. Griffon's SOFR loans accrue interest at Term SOFR plus a credit adjustment spread and a margin of 2.00% (7.43% at March 31, 2024); SONIA loans accrue interest at SONIA Base Rate plus a credit adjustment spread and a margin of 2.00% (7.22% at March 31, 2024); and base rate loans accrue interest at prime rate plus a margin of 1.00% (9.50% at March 31, 2024). At March 31, 2024, under the Revolver, there were $169,500 in outstanding borrowings; outstanding standby letters of credit were $12,962; and $317,538 was available, subject to certain loan covenants, for borrowing at that date. On January 24, 2022, Griffon amended and restated its Credit Agreement to provide for a new $800,000 Term Loan B facility, due January 24, 2029, in addition to the Revolver. The Term Loan B accrues interest at the Term SOFR rate plus a credit adjustment spread with a floor of 0.50%, and a spread of 2.25% (7.70% as of March 31, 2024). The Term Loan B was issued at 99.75% of par value. In connection with this amendment, Griffon capitalized $15,466 of underwriting fees and other expenses incurred, which are being amortized over the term of the loan. The Term Loan B facility requires nominal quarterly principal payments of $2,000, potential additional annual principal payments based on a percentage of excess cash flow and certain secured leverage thresholds starting with the fiscal year ending September 30, 2023; and a final balloon payment due at maturity. At September 30, 2023, Griffon's secured leverage remained below the threshold set forth in the Credit Agreement that would, if exceeded, require Griffon to make an additional payment, and therefore no additional annual principal payment was required. Term Loan B borrowings may generally be repaid without penalty but may not be re-borrowed. During 2023 and 2022, Griffon prepaid $25,000 and $300,000, respectively, aggregate principal amount of the Term Loan B, which permanently reduced the outstanding balance. In connection with the prepayment of the Term Loan B, Griffon recognized a charge of $437 and $6,296 on the prepayment of debt in 2023 and 2022, respectively. The charges were comprised of write-offs of underwriting fees and other expenses of $386 and $5,575 for 2023 and 2022, respectively, and the original issue discount of $51 and $721 for 2023 and 2022, respectively. The Term Loan B facility is subject to the same affirmative and negative covenants that apply to the Revolver (as described below), but is not subject to any financial maintenance covenants. Term Loan B borrowings are secured by the same collateral as the Revolver on an equal and ratable basis. The fair value of the Term Loan B facility approximated $459,574 on March 31, 2024 based upon quoted market prices (level 1 inputs). At March 31, 2024, $6,378 of underwriting fees and other expenses incurred, remained to be amortized. At March 31, 2024, $459,000 of the Term Loan B was outstanding. The Revolver has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio, as well as customary affirmative and negative covenants and events of default. The negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. Both the Revolver and Term Loan B borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors, and a pledge of not greater than 65% of the equity interest in Griffon’s material, first-tier foreign subsidiaries. (c) On September 28, 2023, the Company closed on the exercise of its lease purchase option, as permitted under the lease agreement, to acquire ownership of the manufacturing facility located in Ocala, Florida for a cash purchase price of $23,207. The Ocala lease had a maturity date in 2025 and bore interest at a fixed rate of approximately 5.6%. As a result of exercising the purchase option, the Company no longer has any future lease obligations related to this real estate. The remaining lease liability balance relates to finance equipment leases. Refer to Note 20-Leases for further details. (d) In November 2012, Garant G.P. (“Garant”), a Griffon wholly owned subsidiary, entered into a CAD 15,000 revolving credit facility. Effective in December 2023, the facility was amended to replace the Canadian Dollar Offer Rate with the Canadian Overnight Repo Rate Average ("CORRA"). The facility accrues interest at CORRA or the Canadian Bankers Acceptance Rate plus 1.3% per annum (6.30% using CORRA and 6.35% using the Canadian Bankers Acceptance Rate as of March 31, 2024). The revolving facility matures in December 2024, but is renewable upon mutual agreement with the lender. Garant is required to maintain a certain minimum equity. At March 31, 2024, there were no outstanding borrowings under the revolving credit facility with CAD 15,000 ($11,039 as of March 31, 2024) available. During 2023, Griffon Australia Holdings Pty Ltd and its Australian subsidiaries (collectively, "Griffon Australia") amended its AUD 15,000 receivable purchase facility to AUD 30,000. The receivable purchase facility was renewed in 2024 and now matures in March 2025, but is renewable upon mutual agreement with the lender. The receivable purchase facility accrues interest at BBSY (Bank Bill Swap Rate) plus 1.25% per annum (5.55% at March 31, 2024). At March 31, 2024, there was no balance outstanding under the receivable purchase facility with AUD 30,000 ($19,575 as of March 31, 2024) available. The receivable purchase facility is secured by substantially all of the assets of Griffon Australia and its subsidiaries. Griffon Australia is required to maintain a certain minimum equity level. In July 2018, the AMES Companies UK Ltd and its subsidiaries (collectively, "Ames UK") entered into a GBP 14,000 term loan, GBP 4,000 mortgage loan and GBP 5,000 revolver, which matured in July 2023. Prior to maturity, on June 30, 2023, AMES UK paid off and cancelled the GBP 14,000 term loan and GBP 4,000 mortgage loan. The payoff amounts were GBP 7,525 ($9,543) and GBP 2,451 ($3,108), respectively. Upon maturity in July 2023, the GBP 5,000 revolver had no balance and was not renewed. (e) In February 2024, Griffon repaid in full a loan with the Pennsylvania Industrial Development Authority. The balance in other long-term debt consists primarily of finance leases. At March 31, 2024, Griffon and its subsidiaries were in compliance with the terms and covenants of all credit and loan agreements.

Stockholders' Equity Note [Abstract]
SHAREHOLDERS' EQUITY AND EQUITY COMPENSATION	SHAREHOLDERS’ EQUITY AND EQUITY COMPENSATION During the six months ended March 31, 2024, the Company paid two quarterly cash dividends of $0.15 per share each. During 2023, the Board of Directors approved two quarterly cash dividends of $0.10 per share and two quarterly cash dividends of $0.125 per share, totaling $0.45. Additionally, on April 19, 2023, the Board of Directors declared a special cash dividend of $2.00 per share, paid on May 19, 2023, to shareholders of record as of the close of business on May 9, 2023. The Company currently intends to pay dividends each quarter; however, payment of dividends is determined by the Board of Directors at its discretion based on various factors, and no assurance can be provided as to the payment of future dividends. Dividends paid on shares in the ESOP were used to offset ESOP compensation expense. For all dividends, a dividend payable is established for the holders of restricted shares; such dividends will be released upon vesting of the underlying restricted shares. On May 7, 2024, the Board of Directors declared a quarterly cash dividend of $0.15 per share, payable on June 20, 2024 to shareholders of record as of the close of business on May 29, 2024. On January 29, 2016, shareholders approved the Griffon Corporation 2016 Equity Incentive Plan (the "Original Incentive Plan") pursuant to which, among other things, awards of performance shares, performance units, stock options, stock appreciation rights, restricted shares, restricted stock units, deferred shares and other stock-based awards may be granted. On January 31, 2018, shareholders approved Amendment No. 1 to the Original Incentive Plan pursuant to which, among other things, 1,000,000 shares were added to the Original Incentive Plan; on January 30, 2020, shareholders approved Amendment No. 2 to the Original Incentive Plan, pursuant to which 1,700,000 shares were added to the Original Incentive Plan; on February 17, 2022, shareholders approved the Amended and Restated 2016 Equity Incentive Plan (the “Amended Incentive Plan”), which amended and restated the Original Incentive Plan and pursuant to which, among other things, 1,200,000 shares were added to the Original Incentive Plan; and on March 20, 2024, shareholders approved an amendment to add 2,600,000 shares to the Amended Incentive Plan. Options granted under the Amended Incentive Plan may be either “incentive stock options” or nonqualified stock options, generally expire ten years after the date of grant and are granted at an exercise price of not less than 100% of the fair market value at the date of grant. The maximum number of shares of common stock available for award under the Amended Incentive Plan is 8,850,000 (600,000 of which may be issued as incentive stock options), plus (i) any shares that were reserved for issuance under the Original Incentive Plan as of the effective date of the Original Incentive Plan, and (ii) any shares underlying awards outstanding on such date under the 2011 Incentive Plan that were subsequently canceled or forfeited. As of March 31, 2024, there were 2,377,532 shares available for grant. Compensation expense for restricted stock and restricted stock units is recognized ratably over the required service period based on the fair value of the grant, calculated as the number of shares or units granted multiplied by the stock price on the date of grant, and for performance shares, including performance units, the likelihood of achieving the performance criteria. The Company recognizes forfeitures as they occur. Compensation expense for restricted stock granted to four senior executives is calculated as the maximum number of shares granted, upon achieving certain performance criteria, multiplied by the stock price as valued by a Monte Carlo Simulation Model. Compensation cost related to stock-based awards with graded vesting, generally over a period of three The following table summarizes the Company’s compensation expense relating to all stock-based incentive plans: For the Three Months Ended March 31, For the Six Months Ended March 31, 2024 2023 2024 2023 Restricted stock $ 3,849 $ 5,296 $ 8,877 $ 10,834 ESOP 2,408 1,297 3,797 2,501 Total stock-based compensation $ 6,257 $ 6,593 $ 12,674 $ 13,335 During the first quarter of 2024, Griffon granted 174,104 shares of restricted stock and restricted stock units ("RSUs"). This includes 166,272 shares of restricted stock and 7,832 RSUs granted to 43 executives and key employees, subject to certain performance conditions, with a vesting period of thirty-six months and a total fair value of $8,225, or a weighted average fair value of $47.24 per share.

This includes 387,222 shares of restricted stock granted to four senior executives with a vesting period of thirty-three months and a two-year post-vesting holding period, subject to the achievement of certain performance conditions relating to required levels of return on invested capital and the relative total shareholder return of Griffon's common stock as compared to a market index. So long as the minimum performance conditions are attained, the amount of shares that can vest will range from a minimum of 64,539 to a maximum of 387,222, with the target number of shares being 129,074.

Earnings Per Share [Abstract]
EARNINGS PER SHARE (EPS)	EARNINGS PER SHARE (EPS) Basic EPS was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted EPS was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding plus additional common shares that could be issued in connection with stock-based compensation. The following table is a reconciliation of the share amounts (in thousands) used in computing earnings per share: Three Months Ended March 31, Six Months Ended March 31, 2024 2023 2024 2023 Common shares outstanding 49,637 57,205 49,637 57,205 Unallocated ESOP shares (131) (933) (131) (933) Non-vested restricted stock (2,337) (3,113) (2,337) (3,113) Impact of weighted average shares 777 (121) 1,196 (350) Weighted average shares outstanding - basic 47,946 53,038 48,365 52,809 Incremental shares from stock-based compensation 1,985 — 2,349 — Weighted average shares outstanding - diluted 49,931 53,038 50,714 52,809 Anti-dilutive restricted stock excluded from diluted EPS computation — 2,326 — 2,525 Shares of the ESOP that have been allocated to employee accounts are treated as outstanding in determining earnings per share.

Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In November 2023, the Financial Accounting Standards Board ("FASB") issued ASU No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures. This standard expands disclosures regarding a public entity’s reportable segments and requires additional information about a reportable segment’s expenses, interim segment profit or loss, and how a public entity’s chief operating decision maker uses reported segment profit or loss information in assessing segment performance and allocating resources. The standard does not change the definition of operating segments. This standard is effective for the Company beginning with our fiscal year 2025, with early adoption permitted. The Company is currently evaluating the potential changes to its reportable segment disclosures and related impact on its business and financial reporting processes and information technology systems. The Company does not expect the adoption of this standard to have an impact on its financial position, results of operations, or cash flows. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosure. The standard requires significant additional disclosures focused on income taxes paid and the rate reconciliation table. Specifically, the amendments in the standard require the Company to disclose disaggregated: (1) income taxes paid by federal, state, and foreign taxes, (2) pre-tax income between domestic and foreign, and (3) income tax expense by federal, state and foreign tax expense. The standard also requires the Company to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. This standard is effective for the Company beginning with our fiscal year 2026, with retrospective application permitted. The Company is currently evaluating the potential changes to its income tax disclosures and related impact on its financial reporting processes and information technology systems. The Company does not expect the adoption of this standard to have an impact on its financial position, results of operations, or cash flows. The Company has implemented all new accounting pronouncements that are in effect and that may impact its financial statements, and does not believe that there are any other new accounting pronouncements that have been issued that might have a material impact on its financial position or results of operations.

Restructuring and Related Activities [Abstract]
RESTRUCTURING CHARGES	RESTRUCTURING CHARGES In response to changing market conditions, Griffon announced in May 2023 that CPP is expanding its global sourcing strategy to include long handled tools, material handling, and wood storage and organization product lines. By transitioning these product lines to an asset-light structure, CPP’s operations will be better positioned to serve customers with a more flexible and cost-effective sourcing model that leverages supplier relationships around the world, while improving its competitive positioning in a post-pandemic marketplace. The global sourcing strategy expansion is expected to be complete by the end of calendar 2024. By that time, CPP expects to have reduced its facility footprint by approximately 1.2 million square feet, or approximately 15% of CPP's square footage, and its headcount by approximately 600. Manufacturing Operations have ceased at all affected sites: Camp Hill and Harrisburg, PA; Fairfield, IA; Grantsville, MD; and four wood mills. The closed locations, which have a total net book value of $24,172, have met the held for sale criteria and have been classified as such on our Balance Sheet as of March 31, 2024. Implementation of this strategy over the duration of the project will result in charges of $120,000 to $130,000, including $50,000 to $55,000 of cash charges for employee retention and severance, operational transition, and facility and lease exit costs, and $70,000 to $75,000 of non-cash charges primarily related to asset write-downs. Capital investment in the range of $3,000 to $5,000 will also be required. These costs exclude cash proceeds from the sale of real estate and equipment, which are expected to largely offset the cash charges, and also exclude inefficiencies due to duplicative labor costs and absorption impacts during transition. In the quarter ended March 31, 2024, CPP incurred pre-tax restructuring and related exit costs comprised of cash charges totaling $2,401. The cash charges included $482 for one-time termination benefits and other personnel-related costs and $1,919 for facility exit costs. In the six months ended March 31, 2024, CPP incurred pre-tax restructuring and related exit costs approximating $14,801, comprised of cash charges totaling $6,319 and non-cash, asset-related charges totaling $8,482. The cash charges included $2,329 for one-time termination benefits and other personnel-related costs and $3,990 for facility exit costs. Non-cash charges of $8,482 were recorded to adjust inventory to net realizable value. In both the quarter and six months ended March 31, 2023, CPP incurred pre-tax restructuring and related exit costs approximating $78,334. During both the quarter and six months ended March 31, 2023, cash charges totaled $19,216 and non-cash, asset-related charges totaled $59,118; the cash charges included $8,050 for one-time termination benefits and other personnel-related costs and $11,166 for facility exit costs. Non-cash charges included a $22,018 impairment charge related to certain fixed assets at several manufacturing locations and $37,100 to adjust inventory to net realizable value.

LEASES

Leases [Abstract]
LEASES	LEASES The Company recognizes right-of-use ("ROU") assets and lease liabilities on the balance sheet, with the exception of leases with a term of twelve months or less. The Company determines if an arrangement is a lease at inception. The ROU assets and short and long-term liabilities associated with our Operating leases are shown as separate line items on our Condensed Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, net, other accrued liabilities, and other non-current liabilities. The Company's finance leases are immaterial. ROU assets, along with any other related long-lived assets, are periodically evaluated for impairment. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease payments primarily include rent and insurance costs (lease components). The Company's leases also include non-lease components such as real estate taxes and common-area maintenance costs. The Company elected the practical expedient to account for lease and non-lease components as a single component. In certain of the Company's leases, the non-lease components are variable and in accordance with the standard are therefore excluded from lease payments to determine the ROU asset. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. Our determination of the lease term may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. For operating leases, fixed lease payments are recognized as operating lease cost on a straight-line basis over the lease term. For finance leases and impaired operating leases, the ROU asset is depreciated on a straight-line basis over the remaining lease term, along with recognition of interest expense associated with accretion of the lease liability. For leases with a lease term of 12 months or less (a "Short-term" lease), any fixed lease payments are recognized on a straight-line basis over such term, and are not recognized on the Condensed Consolidated Balance Sheets. Variable lease cost for both operating and finance leases, if any, is recognized as incurred. Components of operating lease costs are as follows: For the Three Months Ended March 31, For the Six Months Ended March 31, 2024 2023 2024 2023 Fixed $ 11,863 $ 11,373 $ 23,437 $ 22,667 Variable (a), (b) 2,436 3,246 4,910 6,018 Short-term (b) 1,081 1,844 2,662 4,048 Total $ 15,380 $ 16,463 $ 31,009 $ 32,733 ________________ (a) Primarily relates to common-area maintenance and property taxes.

On September 28, 2023, the Company closed on the exercise of its lease purchase option, as permitted under the lease agreement, to acquire ownership of the manufacturing facility located in Ocala, Florida for a cash purchase price of $23,207. The Ocala lease had a maturity date in 2025 and bore interest at a fixed rate of approximately 5.6%. As a result of exercising the purchase option, the Company no longer has any future lease obligations related to this real estate. The remaining lease liability balance relates to finance equipment leases.

LEASES	LEASES The Company recognizes right-of-use ("ROU") assets and lease liabilities on the balance sheet, with the exception of leases with a term of twelve months or less. The Company determines if an arrangement is a lease at inception. The ROU assets and short and long-term liabilities associated with our Operating leases are shown as separate line items on our Condensed Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, net, other accrued liabilities, and other non-current liabilities. The Company's finance leases are immaterial. ROU assets, along with any other related long-lived assets, are periodically evaluated for impairment. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease payments primarily include rent and insurance costs (lease components). The Company's leases also include non-lease components such as real estate taxes and common-area maintenance costs. The Company elected the practical expedient to account for lease and non-lease components as a single component. In certain of the Company's leases, the non-lease components are variable and in accordance with the standard are therefore excluded from lease payments to determine the ROU asset. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal and environmental Peekskill Site. Lightron Corporation (“Lightron”), a wholly-owned subsidiary of Griffon, once conducted lamp manufacturing and metal finishing operations at a location in the Town of Cortlandt, New York, just outside the city of Peekskill, New York (the “Peekskill Site”). ISC Properties, Inc. (“ISCP”), a wholly-owned subsidiary of Griffon, owned the Peekskill Site for approximately three years. ISCP sold the Peekskill Site in November 1982. Based upon studies conducted by ISCP and the New York Department of Environmental Conservation, soils and groundwater beneath the Peekskill Site contain chlorinated solvents and metals. Stream sediments downgradient from the Peekskill Site also contain metals. On May 15, 2019 the United States Environmental Protection Agency ("EPA") added the Peekskill Site to the National Priorities List under CERCLA and has since reached agreement with Lightron and ISCP pursuant to which Lightron and ISCP will perform a Remedial Investigation/Feasibility Study (“RI/FS”). Performance of the RI/FS is expected to be completed in calendar 2025. Lightron has not engaged in any operations for over three decades. ISCP functioned solely as a real estate holding company and has not held any real property for over three decades. Griffon does not acknowledge any responsibility to perform any investigation or remediation at the Peekskill Site. Lightron and ISCP are being defended by an insurance company, subject to a reservation of rights, and this insurer is paying the costs of the RI/FS. Memphis, TN site. Hunter Fan Company (“Hunter”) operated headquarters and a production plant in Memphis, TN for over 50 years (the “Memphis Site”). While Hunter completed certain on-site remediation of PCB-contaminated soils, Hunter did not investigate the extent to which PCBs existed beneath the building itself nor determine whether off-site areas had been impacted. Hunter vacated the site approximately twenty years ago, and the on-site buildings have now been demolished. The State of Tennessee Department of Environment and Conservation (“TDEC”) identified the Memphis site as being potentially contaminated, raising the possibility that site operations could have resulted in soil and groundwater contamination involving volatile organic compounds and metals. In 2021, the TDEC performed a preliminary assessment of the site and recommended to the EPA that it include the site on the National Priorities List established under CERCLA. The TDEC further recommended that the EPA fund an investigation of potential soil gas contamination in receptors near the site. The TDEC has also indicated that it will proceed with this investigation if the EPA does not act. It is unknown whether the EPA will add the Memphis Site to the National Priorities List, whether a site investigation will reveal contamination and, if there is contamination, the extent of any such contamination. However, given that certain PCB work was not completed in the past and the TDEC’s stated intent for the EPA to perform an investigation (and the statement by the TDEC that it will perform the investigation if the EPA will not), liability is probable in this matter. There are other potentially responsible parties for this site, including a former owner of Hunter; Hunter has notified such former owner of this matter, which may have certain liability for any required remediation. If the EPA decides to add this site to the National Priorities List, a Remedial Investigation/Feasibility Study (“RI/FS”) will be required. Hunter expects that the EPA will ask it to perform this work. If Hunter does not reach an agreement with the EPA to perform this work, the EPA will implement the RI/FS on its own. Should the EPA implement the RI/FS or perform further studies and/or subsequently remediate the site without first reaching an agreement with one or more relevant parties, the EPA would likely seek reimbursement from such parties, including Hunter, for the costs incurred. General legal Griffon is subject to various laws and regulations relating to the protection of the environment and is a party to legal proceedings arising in the ordinary course of business. Management believes, based on facts presently known to it, that the resolution of the matters above and such other matters will not have a material adverse effect on Griffon’s consolidated financial position, results of operations or cash flows.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information, and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all the information and footnotes required by US GAAP for complete financial statements. As such, they should be read together with Griffon’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023, which provides a more complete explanation of Griffon’s accounting policies, financial position, operating results, business, properties and other matters. In the opinion of management, these financial statements reflect all adjustments considered necessary for a fair statement of interim results. Griffon’s businesses are seasonal; for this and other reasons, the financial results of the Company for any interim period are not necessarily indicative of the results for the full year. The condensed consolidated balance sheet information at September 30, 2023 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2023. The condensed consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Certain amounts in prior years may have been reclassified to conform to the current year presentation. The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. These estimates may be adjusted due to changes in economic, industry or customer financial conditions, as well as changes in technology or demand. Significant estimates include expected loss allowances for credit losses and returns, net realizable value of inventories, restructuring reserves, valuation of goodwill and intangible assets, assumptions associated with pension benefit obligations and income or expenses, useful lives associated with depreciation and amortization of intangible and fixed assets, warranty reserves, sales incentive accruals, assumption associated with stock based compensation valuation, income taxes and tax valuation reserves, environmental reserves, legal reserves, insurance reserves, the valuation of assets and liabilities of discontinued operations and the accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions Griffon may undertake in the future. Actual results may ultimately differ from these estimates.
Fair Value Measurements	The carrying values of cash and equivalents, accounts receivable, accounts and notes payable, and revolving credit and variable interest rate debt approximate fair value due to either the short-term nature of such instruments or the fact that the interest rate of the revolving credit and variable rate debt is based upon current market rates. Applicable accounting guidance establishes a fair value hierarchy requiring the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The accounting guidance establishes three levels of inputs that may be used to measure fair value, as follows: • Level 1 inputs are measured and recorded at fair value based upon quoted prices in active markets for identical assets. • Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities. • Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
Inventories	Inventories are stated at the lower of cost (first-in, first-out or average cost) or net realizable value.
Recent Accounting Pronouncements	In November 2023, the Financial Accounting Standards Board ("FASB") issued ASU No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures. This standard expands disclosures regarding a public entity’s reportable segments and requires additional information about a reportable segment’s expenses, interim segment profit or loss, and how a public entity’s chief operating decision maker uses reported segment profit or loss information in assessing segment performance and allocating resources. The standard does not change the definition of operating segments. This standard is effective for the Company beginning with our fiscal year 2025, with early adoption permitted. The Company is currently evaluating the potential changes to its reportable segment disclosures and related impact on its business and financial reporting processes and information technology systems. The Company does not expect the adoption of this standard to have an impact on its financial position, results of operations, or cash flows. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosure. The standard requires significant additional disclosures focused on income taxes paid and the rate reconciliation table. Specifically, the amendments in the standard require the Company to disclose disaggregated: (1) income taxes paid by federal, state, and foreign taxes, (2) pre-tax income between domestic and foreign, and (3) income tax expense by federal, state and foreign tax expense. The standard also requires the Company to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. This standard is effective for the Company beginning with our fiscal year 2026, with retrospective application permitted. The Company is currently evaluating the potential changes to its income tax disclosures and related impact on its financial reporting processes and information technology systems. The Company does not expect the adoption of this standard to have an impact on its financial position, results of operations, or cash flows. The Company has implemented all new accounting pronouncements that are in effect and that may impact its financial statements, and does not believe that there are any other new accounting pronouncements that have been issued that might have a material impact on its financial position or results of operations.

Proceeds from the 2028 Senior Notes were used to redeem $1,000,000 of 5.25% Senior Notes due 2022. In connection with the issuance and exchange of the 2028 Senior Notes, Griffon capitalized $16,448 of underwriting fees and other expenses incurred, which is being amortized over the term of such notes. During 2022, Griffon purchased $25,225 of 2028 Senior Notes in the open market at a weighted average discount of 91.82% of par, or $23,161. As of March 31, 2024, outstanding 2028 Senior Notes due totaled $974,775; interest is payable semi-annually on March 1 and September 1. The 2028 Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. The 2028 Senior Notes were registered under the Securities Act of 1933, as amended (the "Securities Act") via exchange offer. The fair value of the 2028 Senior Notes approximated $950,406 on March 31, 2024 based upon quoted market prices (level 1 inputs). At March 31, 2024, $7,910 of underwriting fees and other expenses incurred remained to be amortized. (b) On August 1, 2023, Griffon amended and restated its Credit Agreement (as amended, "Credit Agreement"). The amendment increased the maximum borrowing availability on its revolving credit facility from $400,000 to $500,000 (the "Revolver") and extended the maturity date of the Revolver from March 22, 2025 to August 1, 2028. In the event the 2028 Senior Notes are not repaid, refinanced, or replaced prior to December 1, 2027, the Revolver will mature on December 1, 2027. The amendment also modified certain other provisions of the Credit Agreement, including increasing the letter of credit sub-facility under the Revolver from $100,000 to $125,000 and increasing the customary accordion feature from a minimum of $375,000 to a minimum of $500,000. The Revolver also includes a multi-currency sub-facility of $200,000. Borrowings under the Revolver may be repaid and re-borrowed at any time. Interest is payable on borrowings at either a Secured Overnight Financing Rate ("SOFR"), Sterling Overnight Index Average ("SONIA") or base rate benchmark rate, plus an applicable margin, which adjusts based on financial performance. Griffon's SOFR loans accrue interest at Term SOFR plus a credit adjustment spread and a margin of 2.00% (7.43% at March 31, 2024); SONIA loans accrue interest at SONIA Base Rate plus a credit adjustment spread and a margin of 2.00% (7.22% at March 31, 2024); and base rate loans accrue interest at prime rate plus a margin of 1.00% (9.50% at March 31, 2024). At March 31, 2024, under the Revolver, there were $169,500 in outstanding borrowings; outstanding standby letters of credit were $12,962; and $317,538 was available, subject to certain loan covenants, for borrowing at that date. On January 24, 2022, Griffon amended and restated its Credit Agreement to provide for a new $800,000 Term Loan B facility, due January 24, 2029, in addition to the Revolver. The Term Loan B accrues interest at the Term SOFR rate plus a credit adjustment spread with a floor of 0.50%, and a spread of 2.25% (7.70% as of March 31, 2024). The Term Loan B was issued at 99.75% of par value. In connection with this amendment, Griffon capitalized $15,466 of underwriting fees and other expenses incurred, which are being amortized over the term of the loan. The Term Loan B facility requires nominal quarterly principal payments of $2,000, potential additional annual principal payments based on a percentage of excess cash flow and certain secured leverage thresholds starting with the fiscal year ending September 30, 2023; and a final balloon payment due at maturity. At September 30, 2023, Griffon's secured leverage remained below the threshold set forth in the Credit Agreement that would, if exceeded, require Griffon to make an additional payment, and therefore no additional annual principal payment was required. Term Loan B borrowings may generally be repaid without penalty but may not be re-borrowed. During 2023 and 2022, Griffon prepaid $25,000 and $300,000, respectively, aggregate principal amount of the Term Loan B, which permanently reduced the outstanding balance. In connection with the prepayment of the Term Loan B, Griffon recognized a charge of $437 and $6,296 on the prepayment of debt in 2023 and 2022, respectively. The charges were comprised of write-offs of underwriting fees and other expenses of $386 and $5,575 for 2023 and 2022, respectively, and the original issue discount of $51 and $721 for 2023 and 2022, respectively. The Term Loan B facility is subject to the same affirmative and negative covenants that apply to the Revolver (as described below), but is not subject to any financial maintenance covenants. Term Loan B borrowings are secured by the same collateral as the Revolver on an equal and ratable basis. The fair value of the Term Loan B facility approximated $459,574 on March 31, 2024 based upon quoted market prices (level 1 inputs). At March 31, 2024, $6,378 of underwriting fees and other expenses incurred, remained to be amortized. At March 31, 2024, $459,000 of the Term Loan B was outstanding. The Revolver has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio, as well as customary affirmative and negative covenants and events of default. The negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. Both the Revolver and Term Loan B borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors, and a pledge of not greater than 65% of the equity interest in Griffon’s material, first-tier foreign subsidiaries. (c) On September 28, 2023, the Company closed on the exercise of its lease purchase option, as permitted under the lease agreement, to acquire ownership of the manufacturing facility located in Ocala, Florida for a cash purchase price of $23,207. The Ocala lease had a maturity date in 2025 and bore interest at a fixed rate of approximately 5.6%. As a result of exercising the purchase option, the Company no longer has any future lease obligations related to this real estate. The remaining lease liability balance relates to finance equipment leases. Refer to Note 20-Leases for further details. (d) In November 2012, Garant G.P. (“Garant”), a Griffon wholly owned subsidiary, entered into a CAD 15,000 revolving credit facility. Effective in December 2023, the facility was amended to replace the Canadian Dollar Offer Rate with the Canadian Overnight Repo Rate Average ("CORRA"). The facility accrues interest at CORRA or the Canadian Bankers Acceptance Rate plus 1.3% per annum (6.30% using CORRA and 6.35% using the Canadian Bankers Acceptance Rate as of March 31, 2024). The revolving facility matures in December 2024, but is renewable upon mutual agreement with the lender. Garant is required to maintain a certain minimum equity. At March 31, 2024, there were no outstanding borrowings under the revolving credit facility with CAD 15,000 ($11,039 as of March 31, 2024) available. During 2023, Griffon Australia Holdings Pty Ltd and its Australian subsidiaries (collectively, "Griffon Australia") amended its AUD 15,000 receivable purchase facility to AUD 30,000. The receivable purchase facility was renewed in 2024 and now matures in March 2025, but is renewable upon mutual agreement with the lender. The receivable purchase facility accrues interest at BBSY (Bank Bill Swap Rate) plus 1.25% per annum (5.55% at March 31, 2024). At March 31, 2024, there was no balance outstanding under the receivable purchase facility with AUD 30,000 ($19,575 as of March 31, 2024) available. The receivable purchase facility is secured by substantially all of the assets of Griffon Australia and its subsidiaries. Griffon Australia is required to maintain a certain minimum equity level. In July 2018, the AMES Companies UK Ltd and its subsidiaries (collectively, "Ames UK") entered into a GBP 14,000 term loan, GBP 4,000 mortgage loan and GBP 5,000 revolver, which matured in July 2023. Prior to maturity, on June 30, 2023, AMES UK paid off and cancelled the GBP 14,000 term loan and GBP 4,000 mortgage loan. The payoff amounts were GBP 7,525 ($9,543) and GBP 2,451 ($3,108), respectively. Upon maturity in July 2023, the GBP 5,000 revolver had no balance and was not renewed. (e) In February 2024, Griffon repaid in full a loan with the Pennsylvania Industrial Development Authority. The balance in other long-term debt consists primarily of finance leases.

Proceeds from the 2028 Senior Notes were used to redeem $1,000,000 of 5.25% Senior Notes due 2022. In connection with the issuance and exchange of the 2028 Senior Notes, Griffon capitalized $16,448 of underwriting fees and other expenses incurred, which is being amortized over the term of such notes. During 2022, Griffon purchased $25,225 of 2028 Senior Notes in the open market at a weighted average discount of 91.82% of par, or $23,161. As of March 31, 2024, outstanding 2028 Senior Notes due totaled $974,775; interest is payable semi-annually on March 1 and September 1. The 2028 Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. The 2028 Senior Notes were registered under the Securities Act of 1933, as amended (the "Securities Act") via exchange offer. The fair value of the 2028 Senior Notes approximated $950,406 on March 31, 2024 based upon quoted market prices (level 1 inputs). At March 31, 2024, $7,910 of underwriting fees and other expenses incurred remained to be amortized. (b) On August 1, 2023, Griffon amended and restated its Credit Agreement (as amended, "Credit Agreement"). The amendment increased the maximum borrowing availability on its revolving credit facility from $400,000 to $500,000 (the "Revolver") and extended the maturity date of the Revolver from March 22, 2025 to August 1, 2028. In the event the 2028 Senior Notes are not repaid, refinanced, or replaced prior to December 1, 2027, the Revolver will mature on December 1, 2027. The amendment also modified certain other provisions of the Credit Agreement, including increasing the letter of credit sub-facility under the Revolver from $100,000 to $125,000 and increasing the customary accordion feature from a minimum of $375,000 to a minimum of $500,000. The Revolver also includes a multi-currency sub-facility of $200,000. Borrowings under the Revolver may be repaid and re-borrowed at any time. Interest is payable on borrowings at either a Secured Overnight Financing Rate ("SOFR"), Sterling Overnight Index Average ("SONIA") or base rate benchmark rate, plus an applicable margin, which adjusts based on financial performance. Griffon's SOFR loans accrue interest at Term SOFR plus a credit adjustment spread and a margin of 2.00% (7.43% at March 31, 2024); SONIA loans accrue interest at SONIA Base Rate plus a credit adjustment spread and a margin of 2.00% (7.22% at March 31, 2024); and base rate loans accrue interest at prime rate plus a margin of 1.00% (9.50% at March 31, 2024). At March 31, 2024, under the Revolver, there were $169,500 in outstanding borrowings; outstanding standby letters of credit were $12,962; and $317,538 was available, subject to certain loan covenants, for borrowing at that date. On January 24, 2022, Griffon amended and restated its Credit Agreement to provide for a new $800,000 Term Loan B facility, due January 24, 2029, in addition to the Revolver. The Term Loan B accrues interest at the Term SOFR rate plus a credit adjustment spread with a floor of 0.50%, and a spread of 2.25% (7.70% as of March 31, 2024). The Term Loan B was issued at 99.75% of par value. In connection with this amendment, Griffon capitalized $15,466 of underwriting fees and other expenses incurred, which are being amortized over the term of the loan. The Term Loan B facility requires nominal quarterly principal payments of $2,000, potential additional annual principal payments based on a percentage of excess cash flow and certain secured leverage thresholds starting with the fiscal year ending September 30, 2023; and a final balloon payment due at maturity. At September 30, 2023, Griffon's secured leverage remained below the threshold set forth in the Credit Agreement that would, if exceeded, require Griffon to make an additional payment, and therefore no additional annual principal payment was required. Term Loan B borrowings may generally be repaid without penalty but may not be re-borrowed. During 2023 and 2022, Griffon prepaid $25,000 and $300,000, respectively, aggregate principal amount of the Term Loan B, which permanently reduced the outstanding balance. In connection with the prepayment of the Term Loan B, Griffon recognized a charge of $437 and $6,296 on the prepayment of debt in 2023 and 2022, respectively. The charges were comprised of write-offs of underwriting fees and other expenses of $386 and $5,575 for 2023 and 2022, respectively, and the original issue discount of $51 and $721 for 2023 and 2022, respectively. The Term Loan B facility is subject to the same affirmative and negative covenants that apply to the Revolver (as described below), but is not subject to any financial maintenance covenants. Term Loan B borrowings are secured by the same collateral as the Revolver on an equal and ratable basis. The fair value of the Term Loan B facility approximated $459,574 on March 31, 2024 based upon quoted market prices (level 1 inputs). At March 31, 2024, $6,378 of underwriting fees and other expenses incurred, remained to be amortized. At March 31, 2024, $459,000 of the Term Loan B was outstanding. The Revolver has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio, as well as customary affirmative and negative covenants and events of default. The negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. Both the Revolver and Term Loan B borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors, and a pledge of not greater than 65% of the equity interest in Griffon’s material, first-tier foreign subsidiaries. (c) On September 28, 2023, the Company closed on the exercise of its lease purchase option, as permitted under the lease agreement, to acquire ownership of the manufacturing facility located in Ocala, Florida for a cash purchase price of $23,207. The Ocala lease had a maturity date in 2025 and bore interest at a fixed rate of approximately 5.6%. As a result of exercising the purchase option, the Company no longer has any future lease obligations related to this real estate. The remaining lease liability balance relates to finance equipment leases. Refer to Note 20-Leases for further details. (d) In November 2012, Garant G.P. (“Garant”), a Griffon wholly owned subsidiary, entered into a CAD 15,000 revolving credit facility. Effective in December 2023, the facility was amended to replace the Canadian Dollar Offer Rate with the Canadian Overnight Repo Rate Average ("CORRA"). The facility accrues interest at CORRA or the Canadian Bankers Acceptance Rate plus 1.3% per annum (6.30% using CORRA and 6.35% using the Canadian Bankers Acceptance Rate as of March 31, 2024). The revolving facility matures in December 2024, but is renewable upon mutual agreement with the lender. Garant is required to maintain a certain minimum equity. At March 31, 2024, there were no outstanding borrowings under the revolving credit facility with CAD 15,000 ($11,039 as of March 31, 2024) available. During 2023, Griffon Australia Holdings Pty Ltd and its Australian subsidiaries (collectively, "Griffon Australia") amended its AUD 15,000 receivable purchase facility to AUD 30,000. The receivable purchase facility was renewed in 2024 and now matures in March 2025, but is renewable upon mutual agreement with the lender. The receivable purchase facility accrues interest at BBSY (Bank Bill Swap Rate) plus 1.25% per annum (5.55% at March 31, 2024). At March 31, 2024, there was no balance outstanding under the receivable purchase facility with AUD 30,000 ($19,575 as of March 31, 2024) available. The receivable purchase facility is secured by substantially all of the assets of Griffon Australia and its subsidiaries. Griffon Australia is required to maintain a certain minimum equity level. In July 2018, the AMES Companies UK Ltd and its subsidiaries (collectively, "Ames UK") entered into a GBP 14,000 term loan, GBP 4,000 mortgage loan and GBP 5,000 revolver, which matured in July 2023. Prior to maturity, on June 30, 2023, AMES UK paid off and cancelled the GBP 14,000 term loan and GBP 4,000 mortgage loan. The payoff amounts were GBP 7,525 ($9,543) and GBP 2,451 ($3,108), respectively. Upon maturity in July 2023, the GBP 5,000 revolver had no balance and was not renewed. (e) In February 2024, Griffon repaid in full a loan with the Pennsylvania Industrial Development Authority. The balance in other long-term debt consists primarily of finance leases.
