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). On June 27, 2022, we completed the sale of our Defense Electronics segment which consisted of our Telephonics subsidiary for $330,000 in cash. As a result, the results of operations of our Telephonics business is classified as a discontinued operation in the Consolidated Statements of Operations for all periods presented and classified the related assets and liabilities associated with the discontinued operation in the consolidated balance sheets. Accordingly, all references made to results and information in this Quarterly Report on Form 10-Q are to Griffon's continuing operations, unless noted otherwise. On May 16, 2022, Griffon announced that its Board of Directors initiated a process to review a comprehensive range of strategic alternatives to maximize shareholder value including a sale, merger, divestiture, recapitalization or other strategic transaction, and on April 20, 2023, Griffon announced that its Board of Directors, after extensive evaluation and deliberation, determined that the ongoing execution of the Company’s strategic plan was the best way to maximize value for shareholders and unanimously decided to conclude its review. On January 24, 2022, Griffon acquired Hunter Fan Company (“Hunter”), a market leader in residential ceiling, commercial, and industrial fans, from MidOcean Partners (“MidOcean”) for a contractual purchase price of approximately $845,000. Hunter, which is part of Griffon's Consumer and Professional Products segment, complements and diversifies our portfolio of leading consumer brands and products. We financed the acquisition of Hunter with a new $800,000 seven year Term Loan B facility; we used a combination of cash on hand and revolving credit facility borrowings to fund the balance of the purchase price and related acquisition and debt expenditures. Griffon conducts its operations through two reportable segments: • Consumer and Professional Products (“CPP”) is a leading North American manufacturer and a 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. • 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. Update on COVID-19 on our Business As of the date of this filing, government restrictions have been relaxed or eliminated as the health risk of COVID-19 has decreased; however, the effects of COVID-19 continue to linger throughout the global economy and our businesses. Though the severity of COVID-19 has subsided, new variants could interrupt business, cause renewed labor and supply chain disruptions, and negatively impact the global and US economy, which could materially and adversely impact our businesses. See information provided in Part 1, Item 1A, “Risk Factors” our Form 10-K filed on November 18, 2022. 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, 2022, 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, in particular its CPP operations, 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, 2022 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2022. The condensed consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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, sales, 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, assumptions associated with valuation of acquired assets and assumed liabilities of acquired companies 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. Certain amounts in the prior year have been reclassified to conform to current year presentation.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended
	Mar. 31, 2023
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, 2023, the fair values of Griffon’s 2028 senior notes and Term Loan B facility approximated $901,667 and $489,540, respectively. Fair values were based upon quoted market prices (level 1 inputs). Insurance contracts with values of $3,619 at March 31, 2023 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 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. 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, 2023, 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, 2023, Griffon had $23,000 of Australian dollar contracts at a weighted average rate of $1.42 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 $1,172 ($820, net of tax) at March 31, 2023. Upon settlement, gains of $155 and $2,416 were recorded in COGS during the three and six months ended March 31, 2023, respectively. All contracts expire in 28 to 90 days. At March 31, 2023, Griffon had $32,750 of Chinese Yuan contracts at a weighted average rate of $6.90 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 Cost of goods and services ("COGS"). AOCI included deferred gains of $655 ($478, net of tax) at March 31, 2023. Upon settlement, losses of $146 and $1,403 were recorded in COGS during the three and six months ended March 31, 2023, respectively. All contracts expire in 4 to 335 days.

REVENUE

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, 2022. See Note 13 - Business Segments for revenue from contracts with customers disaggregated by end markets, segments and geographic location.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS	ACQUISITIONS Griffon continually evaluates potential acquisitions that strategically fit within its portfolio or expand its portfolio into new product lines or adjacent markets. Griffon has completed a number of acquisitions that have been accounted for as business combinations, in which assets acquired and liabilities assumed are recorded at fair value as of the date of acquisition and have resulted in the recognition of goodwill. The operating results of the business acquisitions are included in Griffon’s consolidated financial statements from the date of acquisition; in each instance, Griffon is in the process of finalizing the initial purchase price allocation unless otherwise noted. On January 24, 2022, Griffon acquired Hunter, a market leader in residential ceiling, commercial, and industrial fans, from MidOcean for a contractual purchase price of $845,000. The acquisition was primarily financed with a new $800,000 seven year Term Loan B facility; we used a combination of cash on hand and revolver borrowings to fund the balance of the purchase price and related acquisition and debt expenditures. Hunter complements and diversifies Griffon's portfolio of leading consumer brands and products. For the six months ended March 31, 2023, Hunter's revenue and Segment Adjusted EBITDA was $130,326 and $16,659, respectively. Based on the final purchase price allocation, the goodwill recognized was $250,711, which was assigned to the CPP segment, and is not deductible for income tax purposes. The following unaudited proforma summary from continuing operations presents consolidated information as if the Company acquired Hunter on October 1, 2020: Proforma For the Three Months Ended March 31, 2022 (unaudited) Proforma For the Six Months Ended March 31, 2022 (unaudited) Revenue $ 791,038 $ 1,461,877 Income from continuing operations 55,151 75,125 Griffon did not include any material, nonrecurring proforma adjustments directly attributable to the business combination in the proforma revenue and earnings. These proforma amounts have been compiled by adding the historical results from continuing operations of Griffon, restated for classifying the results of operations of the Telephonics business as a discontinued operation, to the historical results of Hunter after applying Griffon’s accounting policies and the following proforma adjustments: • Depreciation and amortization that would have been charged assuming the preliminary fair value adjustments to property, plant, and equipment, and intangible assets had been applied from October 1, 2021. • Additional interest and related expenses from the new $800,000 seven year Term Loan B facility that Griffon used to acquire Hunter Fan reduced by historical Hunter interest expense. • The tax effects on the above adjustments using the statutory tax rate of 25.7% for Griffon and 27.1% for Hunter. The calculation of the final purchase price allocation is as follows: Accounts receivable (1) $ 64,602 Inventories (2) 110,299 Other current assets 7,940 Property, plant and equipment 15,007 Operating lease right-of-use assets 12,447 Goodwill 250,711 Intangible assets 616,000 Total assets acquired $ 1,077,006 Accounts payable and accrued liabilities $ 70,039 Current portion of operating lease liabilities 3,323 Deferred tax liability (3) 139,219 Long-term operating lease liabilities 9,123 Other long-term liabilities 3,848 Total liabilities assumed $ 225,552 Total net assets acquired $ 851,454 (1) Includes $67,201 of gross accounts receivable of which $2,599 was not expected to be collected.

CREDIT LOSSES

CREDIT LOSSES	6 Months Ended

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 credit losses that is deducted from the amortized cost basis of accounts receivable to present the net amount expected to be collected: Six months ended March 31, 2023 2022 Beginning Balance, October 1 $ 12,137 $ 8,787 Allowance for credit losses acquired — 2,599 Provision for expected credit losses 2,395 1,889 Amounts written off charged against the allowance (723) (10) Other, primarily foreign currency translation (554) 235 Ending Balance, March 31 $ 13,255 $ 13,500

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLES	GOODWILL AND OTHER INTANGIBLES For the quarter ended March 31, 2023, indicators of goodwill impairment were present for our CPP reporting units driven by a decrease in year-to-date and forecasted sales and operating results due to elevated customer inventory levels and reduced consumer demand. As such, in connection with the preparation of our financial statements for the quarter ended March 31, 2023, we performed a quantitative assessment of the CPP reporting units goodwill using both an income based and market-based valuation approach. The impairment test did not result in a goodwill impairment. Indicators of impairment were not present for the HBP reporting unit. The following table provide a summary of the carrying value of goodwill by segment as of September 30, 2022 and March 31, 2023, as follows: At September 30, 2022 Hunter Acquisition (1) At March 31, 2023 Consumer and Professional Products $ 144,537 $ (7,926) $ 136,611 Home and Building Products 191,253 — 191,253 Total $ 335,790 $ (7,926) $ 327,864 (1) The decrease is due to the final allocation of the purchase price for the Hunter acquisition primarily related to deferred taxes. In connection with the preparation of our financial statements for the quarter ended March 31, 2023, indicators of impairment were present for our CPP indefinite-lived intangible assets. As such, we determined the fair values of the indefinite-lived intangible assets by using a relief from royalty method, which estimates the value of a trademark by discounting to present value the hypothetical royalty payments that are saved by owning the asset rather than licensing it. We compared the estimated fair values to their carrying amounts. The impairment test resulted in a pre-tax, non-cash impairment charge of $100,000 ($74,256, net of tax) to the gross carrying amount of our trademarks. The following table provides the gross carrying value and accumulated amortization for each major class of intangible assets: At March 31, 2023 At September 30, 2022 Gross Carrying Amount Accumulated Average Gross Carrying Amount Accumulated Customer relationships & other $ 444,013 $ 102,786 23 $ 442,085 $ 91,143 Technology and patents 14,904 3,389 13 14,326 3,022 Total amortizable intangible assets 458,917 106,175 456,411 94,165 Trademarks 303,169 — 399,668 — Total intangible assets $ 762,086 $ 106,175 $ 856,079 $ 94,165 The gross carrying amount of intangible assets was impacted by $6,007 related to favorable foreign currency translation.

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. In connection with these purchases, Griffon recognized a $1,767 net gain on the early extinguishment of debt comprised of $2,064 of face value in excess of purchase price, offset by $297 related to the write-off of underwriting fees and other expenses. As of March 31, 2023, 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 $901,667 on March 31, 2023 based upon quoted market prices (level 1 inputs). At March 31, 2023, $9,930 of underwriting fees and other expenses incurred remained to be amortized. (b) On January 24, 2022, Griffon amended and restated its Revolving Credit Facility (as amended, "Credit Agreement") to provide for a new $800,000 Term Loan B facility, due January 24, 2029, in addition to its $400,000 revolving credit facility ("Revolver"), and replaced LIBOR with SOFR (Secured Overnight Financing Rate). The Term Loan B accrues interest at the Term SOFR rate plus a credit adjustment spread with a floor of 0.50%, and at March 31, 2023 a spread of 2.50% (7.55% as of March 31, 2023). The Original Issue Discount for the Term Loan B was 99.75%. 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. Term Loan B borrowings may generally be repaid without penalty but may not be re-borrowed. During 2022, Griffon prepaid $300,000 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 $6,296 charge on the prepayment of debt; $5,575 related to the write-off of underwriting fees and other expenses and $721 of the original issuer discount. The Term Loan B facility is subject to the same affirmative and negative covenants that apply to the Revolver, 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 $489,540 on March 31, 2023 based upon quoted market prices (level 1 inputs). At March 31, 2023, $8,120 of underwriting fees and other expenses incurred, remained to be amortized. The Revolver's maximum borrowing availability is $400,000 and it matures on March 22, 2025. The Revolver includes a letter of credit sub-facility with a limit of $100,000; a multi-currency sub-facility of $200,000; and contains a customary accordion feature that permits us to request, subject to each lender's consent, an increase in the maximum aggregate amount that can be borrowed by up to an additional $100,000. During 2022, Griffon replaced the Revolver GBP LIBOR benchmark rate with a Sterling Overnight Index Average ("SONIA"). Borrowings under the Revolver may be repaid and re-borrowed at any time. Interest is payable on borrowings at either a SOFR, SONIA or base rate benchmark rate, plus an applicable margin, which adjusts based on financial performance. Griffon's SONIA loans accrue interest at SONIA Base Rate plus a credit adjustment spread and a margin of 1.50% (5.71% at March 31, 2023). 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. At March 31, 2023, there were $30,880 of outstanding borrowings under the Revolver; outstanding standby letters of credit were $12,807; and $356,313 was available, subject to certain loan covenants, for borrowing at that date. (c) Griffon has one finance lease outstanding for real estate located in Ocala, Florida. The lease matures in 2025 and bears interest at a fixed rate of approximately 5.6%. The Ocala, Florida lease contains two five-year renewal options. At March 31, 2023, $12,406 was outstanding. During 2022, the financing lease on the Troy, Ohio location expired. The lease bore interest at a rate of approximately 5.0%, was secured by a mortgage on the real estate, which was guaranteed by Griffon, and had a one dollar buyout at the end of the lease. Griffon exercised the one dollar buyout option in November 2021. Refer to Note 21- Leases for further details. (d) In November 2012, Garant G.P.

Stockholders' Equity Note [Abstract]
SHAREHOLDERS' EQUITY AND EQUITY COMPENSATION	SHAREHOLDERS’ EQUITY AND EQUITY COMPENSATION During the six months ended March 31, 2023, the Company paid two quarterly cash dividends of $0.10 per share each. On May 2, 2023, the Board of Directors declared a quarterly cash dividend of $0.125 per share, payable on June 15, 2023 to shareholders of record as of the close of business on May 25, 2023. On April 20, 2023, the Board of Directors declared a special cash dividend of $2.00 per share, payable on May 19, 2023, to shareholders of record as of the close of business on May 9, 2023. During 2022, the Company paid a regular quarterly cash dividend of $0.09 per share, totaling $0.36 per share for the year. Additionally, on June 27, 2022, the Board of Directors declared a special cash dividend of $2.00 per share, paid on July 20, 2022. 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 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; and 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. 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 6,250,000 (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, 2023, there were 328,473 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 two 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.

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, 2023 2022 2023 2022 Common shares outstanding 57,205 57,032 57,205 57,032 Unallocated ESOP shares (933) (1,769) (933) (1,769) Non-vested restricted stock (3,113) (3,533) (3,113) (3,533) Impact of weighted average shares (121) (62) (350) (307) Weighted average shares outstanding - basic 53,038 51,668 52,809 51,423 Incremental shares from stock-based compensation — 1,762 — 2,179 Weighted average shares outstanding - diluted 53,038 53,430 52,809 53,602 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.

RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In October 2021, the Financial Accounting Standards Board ("FASB") issued ASU No. 2021-08, Business Combinations (Topic 805); Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . This new guidance affects all entities that enter into a business combination within the scope of ASC 805-10. Under this new guidance, the acquirer should determine what contract assets and/or liabilities it would have recorded under ASC 606 (Revenue Guidance) as of the acquisition date, as if the acquirer had entered into the original contract at the same date and on the same terms as the acquirer. Under current U.S. GAAP, contract assets and contract liabilities acquired in a business combination are recorded by the acquirer at fair value. This update is effective for the Company beginning in fiscal 2023. Adoption of this standard did not have a material impact on our consolidated financial statements and the related disclosures. 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.

DISCONTINUED OPERATIONS	DISCONTINUED OPERATIONS On September 27, 2021, Griffon announced it was exploring strategic alternatives for its DE segment, which consisted of its Telephonics subsidiary. On June 27, 2022, Griffon completed the sale of Telephonics to TTM for $330,000 in cash, excluding $2,568 for post-closing working capital adjustments. In connection with the sale of Telephonics, the Company recorded a gain of $107,517 ($89,241, net of tax) for the year ended September 30, 2022. The gain and related tax for the sale of Telephonics is preliminary and is subject to finalization. In accordance with ASC 205-20 Presentation of Financial Statements: Discontinued Operations, a disposal of a component of an entity or a group of components of an entity is required to be reported as discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the component of an entity meets the criteria in paragraph 205-20-45-10. In the period in which the component meets held-for-sale or discontinued operations criteria, the major current assets, other assets, current liabilities, and noncurrent liabilities shall be reported as components of total assets and liabilities separate from those balances of the continuing operations. At the same time, the results of all discontinued operations, less applicable income taxes (benefit), shall be reported as components of net income (loss) separate from the net income (loss) of continuing operations. Defense Electronics (DE or Telephonics) The following amounts related to Telephonics have been segregated from Griffon's continuing operations and are reported as a discontinued operation: For the Three Months Ended March 31, 2022 For the Six Months Ended March 31, 2022 Revenue $ 56,273 $ 110,266 Cost of goods and services 45,188 86,149 Gross profit 11,085 24,117 Selling, general and administrative expenses 10,289 20,309 Income from discontinued operations 796 3,808 Other income (expense) Interest income, net 2 2 Other, net 202 510 Total other income (expense) 204 512 Income from discontinued operations before taxes $ 1,000 $ 4,320 Provision for income taxes (6,529) (5,803) Income from discontinued operations $ 7,529 $ 10,123 Depreciation and amortization was excluded from the prior year results since DE was classified as a discontinued operation and, accordingly, the Company ceased depreciation and amortization in accordance with discontinued operations accounting guidelines. Depreciation and amortization would have been approximately $2,400 and $5,100 for the quarter and six months ended March 31, 2022, respectively. The following amounts summarize the total assets and liabilities related to Telephonics, Installation Services and other discontinued activities which have been segregated from Griffon’s continuing operations, and are reported as assets and liabilities of discontinued operations in the Condensed Consolidated Balance Sheets: At March 31, 2023 At September 30, 2022 Assets of discontinued operations: Prepaid and other current assets $ 1,004 $ 1,189 Other long-term assets 4,188 4,586 Total assets of discontinued operations $ 5,192 $ 5,775 Liabilities of discontinued operations: Accrued liabilities, current $ 7,460 $ 12,656 Other long-term liabilities 5,720 4,262 Total liabilities of discontinued operations $ 13,180 $ 16,918 At March 31, 2023 and September 30, 2022, Griffon's discontinued assets and liabilities includes the Company's obligation of $4,587 and $8,846, respectively, in connection with the sale of Telephonics primarily related to certain customary post-closing adjustments, primarily working capital and stay bonuses.

Restructuring and Related Activities [Abstract]
RESTRUCTURING CHARGES	RESTRUCTURING CHARGES On May 3, 2023, in response to changing market conditions, Griffon announced that its CPP segment will expand 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. Over that period, CPP expects to reduce its facility footprint by approximately 1.2 million square feet, or approximately 15%, and its headcount by approximately 600. The affected U.S. locations will include Camp Hill and Harrisburg, PA; Grantsville, MD; Fairfield, IA; and four wood mills. 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 both the quarter and six months ended March 31, 2023, CPP incurred pre-tax restructuring and related exit costs approximating $78,334. During the six 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. In November 2019, Griffon announced the development of a next-generation business platform for CPP to enhance the growth, efficiency, and competitiveness of its U.S. operations, and on November 12, 2020, Griffon announced that CPP was broadening this strategic initiative to include additional North American facilities, the AMES United Kingdom (U.K.) and Australia businesses, and a manufacturing facility in China. On April 28, 2022, Griffon announced a reduced scope and accelerated timeline for the initiative, which was completed in fiscal 2022. The cost to implement this new business platform, over the duration of the project, included one-time charges of approximately $51,869 and capital investments of approximately $15,000, net of future proceeds from the sale of exited facilities. Total cumulative charges of $51,869 consisted of cash charges totaling $35,691 and non-cash, asset-related charges totaling $16,178; the cash charges included $12,934 for one-time termination benefits and other personnel-related costs and $22,757 for facility exit costs. As a result of these transactions, headcount was reduced by approximately 420. In the quarter and six months ended March 31, 2022, CPP incurred pre-tax restructuring and related exit costs approximating $4,766 and $6,482, respectively.

LEASES

Leases [Abstract]
LEASES	LEASESThe 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, 2023 2022 2023 2022 Fixed $ 11,373 $ 9,906 $ 22,667 $ 19,653 Variable (a), (b) 3,246 1,684 6,018 3,536 Short-term (b) 1,844 1,486 4,048 2,835 Total $ 16,463 $ 13,076 $ 32,733 $ 26,024 (a) Primarily relates to common-area maintenance and property taxes.

Griffon has one finance lease outstanding for real estate located in Ocala, Florida. The lease matures in 2025 and bears interest at a fixed rate of approximately 5.6%. The Ocala, Florida lease contains two five-year renewal options. At March 31, 2023, $12,406 was outstanding. During 2022, the financing lease on the Troy, Ohio location expired. The lease bore interest at a rate of approximately 5.0%, was secured by a mortgage on the real estate, which was guaranteed by Griffon, and had a one dollar buyout at the end of the lease. Griffon exercised the one dollar buyout option in November 2021. The remaining lease liability balance relates to finance equipment leases.

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”) which was owned by ISC Properties, Inc. (“ISCP”), a wholly-owned subsidiary of Griffon, 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 by early calendar 2024. Lightron has not engaged in any operations in over three decades. ISCP functioned solely as a real estate holding company and has not held any real property in over three decades. Griffon does not acknowledge any responsibility to perform any investigation or remediation at the Peekskill Site. One of Griffon’s insurers is defending Lightron, ISCP and Griffon subject to a reservation of rights and 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 United States Environmental Protection Agency (“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, 2022, 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, in particular its CPP operations, 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, 2022 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2022. The condensed consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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, sales, 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, assumptions associated with valuation of acquired assets and assumed liabilities of acquired companies 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. Certain amounts in the prior year have been reclassified to conform to current year presentation.
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 October 2021, the Financial Accounting Standards Board ("FASB") issued ASU No. 2021-08, Business Combinations (Topic 805); Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . This new guidance affects all entities that enter into a business combination within the scope of ASC 805-10. Under this new guidance, the acquirer should determine what contract assets and/or liabilities it would have recorded under ASC 606 (Revenue Guidance) as of the acquisition date, as if the acquirer had entered into the original contract at the same date and on the same terms as the acquirer. Under current U.S. GAAP, contract assets and contract liabilities acquired in a business combination are recorded by the acquirer at fair value. This update is effective for the Company beginning in fiscal 2023. Adoption of this standard did not have a material impact on our consolidated financial statements and the related disclosures. 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.
