NOTE 1 – 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 divestitures. As long-term investors, we intend to continue to grow and strengthen our existing businesses, and to diversify further through investments in our businesses and acquisitions.

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 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, 2024, 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, 2024 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2024.

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, assumptions 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.

NOTE 2 – 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 December 31, 2024, the fair values of Griffon’s 2028 Senior Notes and Term Loan B facility approximated $950,406 and $457,275, respectively. Fair values were based upon quoted market prices (level 1 inputs).

Insurance contracts with values of $4,858 at December 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 other assets on the Condensed 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 December 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 December 31, 2024, Griffon had $43,500 of Australian Dollar contracts at a weighted average rate of $1.47 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 $3,844 ($2,690, net of tax) at December 31, 2024. Upon settlement, gains of $955 were recorded in COGS during the three months ended December 31, 2024. All contracts expire in 30 to 150 days.

At December 31, 2024, Griffon had $33,500 of Chinese Yuan contracts at a weighted average rate of $7.08 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 $1,043 ($762, net of tax) at December 31, 2024. Upon settlement, losses of $220 were recorded in COGS during the three months ended December 31, 2024. All contracts expire in 3 to 304 days.

At December 31, 2024, Griffon had $10,335 of Canadian Dollar contracts at a weighted average rate of $1.35. The contracts, which protect Canadian operations from currency fluctuations for U.S. Dollar based purchases, do not qualify for hedge accounting. For the three months ended December 31, 2024, fair value gains of $242 were recorded to Other liabilities and to Other income for the outstanding contracts, based on similar contract values (level 2 inputs). Realized gains of $46 were recorded in Other income during the three months ended December 31, 2024 for all settled contracts. All contracts expire in 30 to 269 days.

NOTE 3 – 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, 2024. See Note 13 - Reportable Segments for revenue from contracts with customers disaggregated by end markets, segments and geographic location.

NOTE 4 – ACQUISITIONS

Griffon continually evaluates potential acquisitions that either 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 business acquisitions are included in Griffon’s consolidated financial statements from the date of acquisition.

On July 1, 2024, Griffon announced that its subsidiary, The AMES Companies, Inc., ("AMES") expanded the scope of its Australian operations by acquiring substantially all of the assets of Pope, a leading Australian provider of residential watering products, from the Toro Company (NYSE:TTC) for a purchase price of approximately AUD 21,800 (approximately $14,500) in cash. The purchase price was preliminarily allocated to inventory of AUD 16,581 (approximately $11,051), goodwill of AUD 2,225 (approximately $1,483) and acquired intangibles, net of deferred taxes, of AUD 2,940 (approximately $1,960), which was assigned to the CPP segment, and is not deductible for income tax purposes.

The net book value of these properties as of December 31, 2024 and September 30, 2024 totaled $5,559 and $14,532, respectively.

During the three months ended December 31, 2024, no event or indicator of impairment occurred which would require additional impairment testing of property, plant and equipment.

NOTE 7 – 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:


	Three months ended December 31,

(Unaudited)

(a) During 2020, Griffon issued, at par, $1,000,000 of 5.75% Senior Notes due 2028 (the “2028 Senior Notes”). Proceeds from the 2028 Senior Notes were used to redeem $1,000,000 of 5.25% Senior Notes due in 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 December 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 an exchange offer. The fair value of the 2028 Senior Notes approximated $950,406 on December 31, 2024 based upon quoted market prices (Level 1 inputs). At December 31, 2024, $6,395 of underwriting fees and other expenses incurred remained to be amortized.

(b) On January 24, 2022, Griffon amended and restated its Credit Agreement (the "Credit Agreement") to provide for a new $800,000 Term Loan B facility, due January 24, 2029, in addition to the revolving credit facility (the "Revolver") provided for under the Credit Agreement. The Term Loan B facility was issued at 99.75% of par value. Since that time, 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. As of December 31, 2024, the Term Loan B outstanding balance was $455,000.

On June 26, 2024, Griffon further amended its Credit Agreement to favorably reprice the Term Loan B facility. The amendment reduced the margin above Secured Overnight Financing Rate ("SOFR") by 0.25%, eliminated the credit spread adjustment and reduced the SOFR floor from 0.50% to 0%. In connection with the amendment, Griffon recognized a $1,700 loss on debt extinguishment primarily consisting of the write-off of unamortized debt issuance costs and original issue discount related to portions of the Term Loan B facility that were repaid and then reborrowed from new lenders. At December 31, 2024, unamortized costs of $5,107 related to existing and new Term Loan B facility lenders will continue to be amortized over the term of the loan.

The Term Loan B bears interest at the Term SOFR rate plus a spread of 2.25% (6.58% as of December 31, 2024). The Term Loan B facility continues to require 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 and a final balloon payment due at maturity. Term Loan B borrowings may generally be repaid without penalty. Once repaid, Term Loan B borrowings may not be reborrowed. 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 that secures borrowings under the Revolver, on an equal and ratable basis. The fair value of the Term Loan B facility approximated $457,275 on December 31, 2024 based upon quoted market prices (Level 1 inputs).

On August 1, 2023, Griffon amended and restated the Credit Agreement to increase the maximum borrowing availability under the Revolver from $400,000 to $500,000 and extend 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 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% (6.43% at December 31, 2024); SONIA loans accrue interest at SONIA Base Rate plus a credit adjustment spread and a margin of 2.00% (6.73% at December 31, 2024); and base rate loans accrue interest at prime rate plus a margin of 1.00% (8.50% at December 31, 2024).

At December 31, 2024, under the Credit Agreement, there were $59,500 in outstanding borrowings on the Revolver; outstanding standby letters of credit were $12,990; and $427,510 was available, subject to certain loan covenants, for borrowing at that date.

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.

(c) 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 ("CDOR") with the Canadian Overnight Repo Rate Average ("CORRA"). The facility accrues interest at CORRA plus 1.3% per annum (4.60% as of December 31, 2024). The revolving facility matured in December 2024. In January 2025, Garant entered into a new CAD 20,000 revolving credit facility. The facility accrues interest at CORRA plus a credit adjustment spread and margin of 1.2%. Garant is required to maintain a certain minimum equity.

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 Bank Bill Swap Rate plus 1.25% per annum (5.57% at December 31, 2024). At December 31, 2024, there was no balance outstanding under the receivable purchase facility with AUD 30,000 ($18,645 as of December 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.

(d) 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 December 31, 2024, Griffon and its subsidiaries were in compliance with the terms and covenants of its credit and loan agreements.

NOTE 11 — SHAREHOLDERS’ EQUITY AND EQUITY COMPENSATION

During the three months ended December 31, 2024, the Company paid a quarterly cash dividend of $0.18 per share. During fiscal year 2024, the Company paid four quarterly cash dividends of $0.15 per share.

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 Griffon's Employee Stock Ownership Plan (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.

The ESOP was frozen as of September 30, 2024; this means that, for plan years after this date, no additional employees will become participants under the ESOP and no new voluntary contributions will be made to the ESOP. Prior to this date, the Company’s U.S. employees who were not members of a collective bargaining agreement and met certain eligibility requirements became participants in the ESOP. During the three months ended December 31, 2024 the final loan payment was made by the ESOP to the Company and compensation expense for the period was fully offset by dividends paid. As of December 31, 2024 there were 4,166,038 shares of common stock in the ESOP, all of which were allocated to participant accounts.

On February 4, 2025, the Board of Directors declared a quarterly cash dividend of $0.18 per share, payable on March 18, 2025 to shareholders of record as of the close of business on February 25, 2025.

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 December 31, 2024, there were 1,893,099 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 to four years, is recognized using the straight-line attribution method and recorded within SG&A expenses.

The following table summarizes the Company’s compensation expense relating to all stock-based incentive plans:


	For the Three Months Ended December 31,
	2024		2023
Restricted stock	$	5,378	$	5,028
ESOP1	—		1,389

________________________

1.During the quarter ended December 31, 2024 the final loan payment was made by the ESOP to the Company and compensation expense for the period was fully offset by dividends paid.

During the first quarter of 2025, Griffon granted 142,911 shares of restricted stock and restricted stock units ("RSUs") 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 $9,735, or a weighted average fair value of $68.12 per share. During the first quarter of 2025, Griffon also granted 436,947 shares of restricted stock to four senior executives with a vesting period of thirty-six 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 72,827 to a maximum of 436,947, with the target number of shares being 145,649. The total estimated fair value of these restricted shares, assuming achievement of the performance conditions at target, is $12,372, or a weighted average fair value of $84.95 per share.

On November 13, 2024, Griffon announced that the Board of Directors approved an additional increase of $400,000 to its share repurchase authorization. Under the authorized share repurchase program, the Company may, from time to time, purchase shares of its common stock in the open market, including pursuant to a 10b5-1 plan, pursuant to an accelerated share repurchase program or issuer tender offer, or in privately negotiated transactions. Share repurchases during the quarter ended December 31, 2024 totaled 610,172 shares of common stock, respectively, for a total of $42,344, or an average of $69.40 per share. As of December 31, 2024, $390,348 remains available under Griffon's Board authorized repurchase program.

During the quarter ended December 31, 2024, $413 was accrued for excise taxes for share repurchases, which was partially offset by the reversal of $74 of excise taxes to adjust for a benefit related to employee vesting and a $104 net benefit on ESOP contributions. As of December 31, 2024, $2,220 was accrued for excise taxes for share repurchases.

NOTE 12 – 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 December 31,

Griffon evaluates performance and allocates resources based on segment adjusted EBITDA and adjusted EBITDA, non-GAAP measures, which are defined as income before taxes, excluding interest income and expense, depreciation and amortization, strategic review charges, non-cash impairment charges, restructuring charges, gain/loss from debt extinguishment and acquisition related expenses, as well as other items that may affect comparability, as applicable. Segment adjusted EBITDA also excludes unallocated amounts, mainly corporate overhead. Griffon believes this information is useful to investors for the same reason. The following table provides a reconciliation of segment adjusted EBITDA and adjusted EBITDA to income before taxes:

The Hunter Fan Pension Plan (the "Plan") was terminated with an effective date of April 30, 2024. This was communicated to Plan participants in February 2024. At the time of termination, the Plan was fully funded and the Company did not anticipate making additional funding contributions as of the benefit distribution dates. During the quarter ended December 31, 2024 the Plan paid lump sum payments in the amount of $4,830 to those participants that elected a lump sum distribution. On January 23, 2025 the Company selected an insurance company to hold the annuity and provide pension benefits to the plan participants currently receiving benefit payments and those that elected to continue their future benefit with an annuity provider. This decision included a transfer of plan assets valued at $10,895. The termination process is expected to be complete in 2025.

NOTE 15 – RECENT ACCOUNTING PRONOUNCEMENTS

Issued but not yet effective accounting pronouncements

In October 2023, the Financial Accounting Standards Board ("FASB") issued ASU No. 2023-06, Disclosure Improvements: Amendments - Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The FASB issued the standard to introduce changes to US GAAP that originate in either SEC Regulation S-X or S-K, which are rules about the form and content of financial reports. The provisions of the standard are contingent when the SEC removes the related disclosure provisions from Regulation S-X and S-K. The company does not expect the provisions of the standard to have a material impact on the Company's financial statements and related disclosures.

In November 2023, the 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 with the Company's fiscal year 2025. The standard should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements.

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, (2) continuing operations pre-tax income between domestic and foreign, and (3) continuing operations income tax expense by federal, state and foreign. 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 a material impact on its financial position, results of operations, or cash flows.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses. This guidance requires disclosures regarding specific information about certain costs and expenses, including but not limited to, inventory purchases, employee compensation, depreciation, amortization and selling expenses. The guidance is effective for the Company beginning with the Company's fiscal year 2027 and interim reporting periods beginning with our 2028 fiscal year. Implementation of this standard may be applied prospectively or retrospectively. The Company does not expect the adoption of this standard to have a material impact on the Company's financial statements and related disclosures.

NOTE 17 – RESTRUCTURING CHARGES

Griffon announced in May 2023 that CPP was expanding its global sourcing strategy to include long handled tools, material handling, and wood storage and organization product lines for the U.S. market. This initiative was successfully completed as of September 30, 2024, ahead of the previously announced date of December 31, 2024.

As a result of this global sourcing expansion initiative, manufacturing operations have concluded at four manufacturing sites and four wood mills, resulting in a total facility footprint reduction of approximately 1.2 million square feet, or approximately 15% of CPP's square footage, and a headcount reduction of approximately 600. The closed locations have met the held for sale criteria and have been classified as such on our Condensed Consolidated Balance Sheets as of December 31, 2024 and September 30, 2024. The net book value of these properties as of December 31, 2024 and September 30, 2024 totaled $5,559 and $14,532, respectively.

The adoption of an asset-light business model for these U.S. products has positioned CPP to better serve customers with a more flexible and cost-effective sourcing model that leverages supplier relationships around the world, and improved its competitive positioning.

Implementation of this strategy over the duration of the project resulted in charges of $133,777, which included $51,082 of cash charges for employee retention and severance, operational transition, and facility and lease exit costs, and $82,695 of non-cash charges primarily related to asset write-downs. In addition, there were $2,678 of capital investments to effectuate the project. This excludes cash proceeds from the sale of real estate and equipment, which at the conclusion of the project as of September 30, 2024 totaled $13,271, and excludes future proceeds from the sale of remaining real estate and equipment designated as held for sale on the condensed consolidated balance sheets. During the quarter ended December 31, 2024, cash proceeds related to the sale of the remaining real estate and equipment held for sale totaled $17,155.

In the quarter ended December 31, 2023, CPP incurred pre-tax restructuring and related exit costs approximating $12,400, comprised of cash charges totaling $3,918 and non-cash, asset-related charges of $8,482. The cash charges included $1,847 for one-time termination benefits and other personnel-related costs and $2,071 for facility exit costs. Non-cash charges of $8,482 were recorded to adjust inventory to its net realizable value.

A summary of the restructuring and other related charges included in Cost of goods and services and SG&A expenses in the Company's Condensed Consolidated Statements of Operations were as follows:


	For the Three Months Ended December 31,
	2023
Cost of goods and services	$	11,646

NOTE 18 – OTHER INCOME (EXPENSE)

For the quarters ended December 31, 2024 and 2023, Other income (expense) of $1,832 and $632, respectively, includes $440 and $13, respectively, of net currency exchange gains in connection with the translation of receivables and payables denominated in currencies other than the functional currencies of Griffon and its subsidiaries, net periodic benefit plan income (expense) of $301 and $(34), respectively, and net investment income of $70 and $56, respectively. Other income (expense) also includes royalty income of $590 and $592 for the three months ended December 31, 2024 and 2023, respectively.

NOTE 19 – WARRANTY LIABILITY

HBP and CPP offer warranties against product defects for periods generally ranging from one to ten years, with limited lifetime warranties on certain door and fan models. Typical warranties require HBP and CPP to repair or replace the defective products during the warranty period at no cost to the customer. At the time revenue is recognized, Griffon records a liability for warranty costs, estimated based on historical experience, and periodically assesses its warranty obligations and adjusts the liability as necessary. CPP offers an express limited warranty for a period of ninety days on all products from the date of original purchase unless otherwise stated on the product or packaging from the date of original purchase. Warranty costs expected to be incurred in the next 12 months are classified in accrued liabilities. Warranty costs expected to be incurred beyond one year are classified in other long-term liabilities. The short-term warranty liability was $13,123 as of December 31, 2024 and $13,050 as of September 30, 2024. The long-term warranty liability was $1,239 at both December 31, 2024 and September 30, 2024.

NOTE 21 — 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 December 31,
	2024		2023
Fixed	$	11,634	$	11,574
Variable (a), (b)	2,667		2,474

NOTE 22 — 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 2025.

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. 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.

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. Since 2021, there has been no further action by the EPA or TDEC relating to the Memphis site.

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.

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.

Overview

Griffon Corporation (the “Company”, “Griffon”, "we" or "us") is a diversified management and holding company that conducts business through wholly-owned subsidiaries. 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).

Business Strategy

Our strategic objective is to maintain leading positions in the markets we serve by providing innovative, branded products with superior quality and industry-leading service. We place emphasis on our iconic and well-respected brands, which helps to differentiate us and our offerings from our competitors and strengthens our relationship with our customers and those who ultimately use our products.

Through operating a diverse portfolio of businesses, we expect to reduce variability caused by external factors such as market cyclicality, seasonality, and weather. We achieve diversity by providing various product offerings and brands through multiple sales and distribution channels and conducting business across multiple countries which we consider our home markets.

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 divestitures. As long-term investors, we intend to continue to grow and strengthen our existing businesses, and to diversify further through investments in our businesses and acquisitions.

Since 2017, we have undertaken a series of transformative transactions to strengthen our core businesses and increase shareholder value. We divested our specialty plastics business in 2018 and our defense electronics (Telephonics) business in 2022 to focus on our core markets and improve our free cash flow conversion. In our Home and Building Products ("HBP") segment, we acquired CornellCookson, Inc. ("CornellCookson") in 2018, which has helped establish us as a leading North American manufacturer and marketer of residential garage doors and sectional commercial doors, and rolling steel doors and grille products, under brands that include Clopay, Ideal, Cornell and Cookson. In our Consumer and Professional Products ("CPP") segment, we expanded the scope of our brands through the acquisition of Hunter Fan Company ("Hunter") in January 2022 and ClosetMaid, LLC ("ClosetMaid") in 2018.

On July 1, 2024, Griffon announced that its subsidiary, The AMES Companies, Inc., ("AMES") expanded the scope of its Australian operations by acquiring substantially all the assets of Pope, a leading Australian provider of residential watering products, from The Toro Company (NYSE:TTC) for a purchase price of approximately AUD 21,800 (approximately $14,500) in cash. This is CPP's seventh acquisition in Australia since 2013, and further expands AMES's product portfolio in the Australian market. Pope is expected to contribute approximately $25,000 in revenue in the first twelve months after this acquisition.

OVERVIEW

Revenue for the quarter ended December 31, 2024 was $632,371 compared to $643,153 in the prior year quarter, a decrease of $10,782 or 2%. The decrease was primarily due to a 4% decline in revenue at CPP, while HBP's revenue remained consistent with the prior year. Net income was $70,851 or $1.49 per share, compared to $42,177, or $0.82 per share, in the prior year quarter.

The current year quarter results from operations included the following:

– Gain on sale of real estate of $7,974 ($5,943, net of tax, or $0.13 per share);

– Strategic review - retention and other of $1,651 ($1,215, net of tax, or $0.03 per share); and

– Discrete and certain other tax benefits, net, of $250 or $0.01 per share.

The prior year quarter results from operations included the following:

– Restructuring charges of $12,400 ($9,213, net of tax, or $0.18 per share);

– Strategic review - retention and other of $4,658 ($3,500, net of tax, or $0.07 per share);

– Gain on sale of real estate of $547 ($406, net of tax, or $0.01 per share); and

– Discrete and certain other tax provisions, net, of $783 or $0.02 per share.

Excluding these items from the respective quarterly results, net income would have been $65,873, or $1.39 per share in the three months ended December 31, 2024 compared to $55,267, or $1.07 per share, in the prior year quarter.

Table of Contents

Griffon evaluates performance based on adjusted net income and the related adjusted earnings per share, which are non-GAAP measures that exclude restructuring charges, non-cash impairment charges, loss from debt extinguishment, acquisition related expenses and discrete and certain other tax items, as well as other items that may affect comparability, as applicable. Griffon believes this information is useful to investors for the same reason. The following table provides a reconciliation of net income from operations to adjusted net income and earnings per share to adjusted earnings per share:

Note: Due to rounding, the sum of earnings per common share and adjusting items, net of tax, may not equal adjusted earnings per common share.

(1) For the three months ended December 31, 2023, restructuring charges relate to the CPP global sourcing expansion, of which $11,646, is included in Cost of goods and services and $754 is included in SG&A in the Company's Condensed Consolidated Statement of Operations.

(2) The tax impact for the above reconciling adjustments from GAAP to non-GAAP Net income and EPS is determined by comparing the Company's tax provision, including the reconciling adjustments, to the tax provision excluding such adjustments.

(3) Discrete and certain other tax provisions (benefits) primarily relate to the impact of a rate differential between the statutory and annual effective tax rates on items impacting the quarter.

RESULTS OF OPERATIONS

Three Months ended December 31, 2024 and 2023

Griffon evaluates performance and allocates resources based on each segment adjusted EBITDA, a non-GAAP measure, which is defined as income before taxes, excluding interest income and expense, depreciation and amortization, unallocated amounts (mainly corporate overhead), strategic review charges, non-cash impairment charges, restructuring charges, and acquisition related expenses, as well as other items that may affect comparability, as applicable. Griffon believes this information is useful to investors for the same reason. See table provided in Note 13 - Reportable Segments for a reconciliation of adjusted EBITDA to income before taxes.

For the quarter ended December 31, 2024, HBP revenue remained consistent with the prior year quarter reflecting increased residential volume, offset by reduced commercial volume.

For the quarter ended December 31, 2024, adjusted EBITDA of $127,042 increased $2,323 or 2%, compared to $124,719 in the prior year quarter, resulting from reduced material costs, partially offset by increased labor and distribution costs.

For the quarter ended December 31, 2024, segment depreciation and amortization increased $642 compared with the prior year quarter due to new assets placed in service.

For the quarter ended December 31, 2024, revenue decreased $10,392, or 4%, compared to the prior year quarter, primarily driven by decreased volume of 8% due to reduced consumer demand in North America and the United Kingdom, partially offset by organic growth in Australia. The Pope acquisition contributed 4%.

For the quarter ended December 31, 2024, adjusted EBITDA of $18,192 increased $12,653 compared to $5,539 in the prior year quarter, primarily due to the benefits from the global sourcing expansion initiative and increased revenue in Australia as noted above.

For the quarter ended December 31, 2024, segment depreciation and amortization increased $161 compared to the prior year period due to new assets placed in service.

Table of Contents

On July 1, 2024 Griffon announced that its subsidiary, AMES expanded the scope of its Australian operations by acquiring substantially all the assets of Pope, a leading Australian provider of residential watering products, from The Toro Company (NYSE:TTC) for a purchase price of approximately AUD 21,800 (approximately $14,500) in cash. This is CPP's seventh acquisition in Australia since 2013, and further expands AMES’s product portfolio in the Australian market. Pope is expected to contribute approximately $25,000 in revenue in the first twelve months after the acquisition.

Unallocated

For the quarter ended December 31, 2024, unallocated amounts, excluding depreciation, consisted primarily of corporate overhead costs totaling $14,042, remained consistent with the prior year quarter of $13,907.

Strategic review

During the three months ended December 31, 2024 and 2023, we incurred strategic review expenses of $1,651 ($1,215, net of tax) and $4,658 ($3,500, net of tax), respectively, primarily for retention payments and other costs related to the strategic review process that concluded in April 2023.

Segment Depreciation and Amortization

For the three months ended December 31, 2024, segment depreciation and amortization of $15,493 increased $803 compared to $14,690 in the prior year quarter; the increase primarily relates to new assets placed in service.

Other Income (Expense)

Provision for income taxes

Stock-based compensation

For the quarters ended December 31, 2024 and 2023, stock based compensation expense, which includes expense for both restricted stock grants and the ESOP, totaled $5,378 and $6,417, respectively. The decrease in stock compensation expense is primarily due to the ESOP being frozen as of September 30, 2024 (meaning that, for plan years after this date, no additional employees will become participants under the ESOP and no new voluntary contributions will be made to the ESOP). Additionally, during the three months ended December 31, 2024 the final loan payment was made by the ESOP to the Company and compensation expense for the period was fully offset by dividends paid. As of December 31, 2024 there were 4,166,038 shares of common stock in the ESOP, all of which were allocated to participant accounts.

Comprehensive income (loss)

For the quarter ended December 31, 2024, total other comprehensive loss, net of taxes, of $17,699 included a loss of $20,018 from foreign currency translation adjustments primarily due to the weakening of the Euro, British Pound and Australian and Canadian Dollar, all in comparison to the U.S. Dollar; a $2,264 gain on cash flow hedges; and a $55 benefit from pension amortization.

Table of Contents

For the quarter ended December 31, 2023, total other comprehensive income, net of taxes, of $10,475 included a gain of $10,238 from foreign currency translation adjustments primarily due to the strengthening of the Euro, British Pound and Australian and Canadian Dollar, all in comparison to the U.S. Dollar; a $295 loss on cash flow hedges; and a $532 benefit from pension amortization.

DISCONTINUED OPERATIONS

At December 31, 2024 and September 30, 2024, Griffon’s liabilities for discontinued operations primarily relate to insurance claims, income taxes, product liability, warranty and environmental reserves totaling $7,604 and $7,768, respectively. Griffon's assets for discontinued operations primarily relate to insurance claims. There was no reported revenues or costs in the three months ended December 31, 2024 and 2023 for discontinued operations.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity

Management assesses Griffon’s liquidity in terms of its ability to generate cash to fund its operating, investing and financing activities. Significant factors affecting liquidity include cash flows from operating activities, capital expenditures, acquisitions, dispositions, bank lines of credit and the ability to attract long-term capital under satisfactory terms. Griffon believes it has sufficient liquidity available to invest in existing businesses and strategic acquisitions while managing its capital structure on both a short-term and long-term basis.

As of December 31, 2024, the amount of cash, cash equivalents and marketable securities held by foreign subsidiaries was $65,700. Our intent is to permanently reinvest these funds, except in limited circumstances, outside the U.S., and we do not currently anticipate that we will need funds generated from foreign operations to fund our domestic operations. The Company may repatriate cash from its non-U.S. subsidiaries if the Company determines that it is beneficial for the company and tax efficient. The Company has accrued a deferred tax liability for withholding taxes on previously taxed earnings and profit (PTEP) which are not considered permanently reinvested. In the event we determine that additional funds from non-U.S. operations are needed to fund operations in the U.S., we will be required to accrue and pay U.S. taxes to repatriate these additional funds.

Griffon's primary sources of liquidity are cash flows generated from operations, cash on hand and our secured $500,000 revolving credit facility ("Revolver"), which matures in August 2028. During the three months ended December 31, 2024, the Company generated $142,922 of net cash from operating activities and, as of December 31, 2024, the Company had $427,510 available, subject to certain loan covenants, for borrowing under the Revolver. The Company had cash and cash equivalents of $151,952 at December 31, 2024.

The following table is derived from the Condensed Consolidated Statements of Cash Flows:


Cash Flows from Operations	For the Three Months Ended December 31,

Financing activities	(108,121)		(123,947)

Cash flows provided by operating activities for the three months ended December 31, 2024 was $142,922, compared to $146,058 in the prior year period. In both the three months ended December 31, 2024 and 2023, cash provided by operating activities reflected increased cash generated primarily from operations at HBP and a decrease in net working capital, primarily driven by a decrease in accounts receivable, and an increase in accounts payable and accrued liabilities.

Cash flows used in investing activities is primarily comprised of capital expenditures and proceeds from the sale of businesses, investments and property, plant and equipment. During the three months ended December 31, 2024, cash flows used in investing activities was $236 compared to $13,543 in the prior year period. Cash flows used in investing activities in the current period primarily consisted of capital expenditures of $17,456, partially offset by proceeds totaling $17,220 primarily from the sale of real estate. In the prior year period, cash flows used in investing activities consisted primarily of capital expenditures of $14,330, partially offset by proceeds totaling $787 from the sale of real estate.

During the three months ended December 31, 2024, cash used in financing activities totaled $108,121 compared to $123,947 in the prior year period. Cash flows used in financing activities in the current period consisted of the purchase of shares of common stock in connection with the board authorized share repurchase program and the purchase of common stock withheld to satisfy tax obligations in connection with the vesting of restricted stock totaling $49,083, the payment of dividends of $9,037 and payments of long-term debt of $50,000, primarily related to the Revolver. Cash flows used in financing activities in the prior year period consisted primarily of net repayments of long-term debt of $32,360, primarily related to the Revolver, the purchase of shares of common stock in connection with the Board authorized share repurchase program and the purchase of common stock withheld to satisfy tax obligations in connection with the vesting of restricted stock of $81,449, and the payment of dividends of $9,965.

During the three months ended December 31, 2024, 64,249 shares, with a market value of $5,417, or $84.31 per share, were withheld to settle employee taxes due upon the vesting of restricted stock, and were added to treasury stock.

During fiscal 2024, the Board of Directors approved four quarterly cash dividends each for $0.15 per share, totaling $0.60 per share for the year. 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.

During 2020, Griffon issued, at par, $1,000,000 of 5.75% Senior Notes due 2028 (the “2028 Senior Notes”). Proceeds from the 2028 Senior Notes were used to redeem $1,000,000 of 5.25% Senior Notes due in 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 December 31, 2024, outstanding 2028 Senior Notes due totaled $974,775; interest is payable semi-annually on March 1 and September 1.

On January 24, 2022, Griffon amended and restated its Credit Agreement (the "Credit Agreement") to provide for a new $800,000 Term Loan B facility, due January 24, 2029, in addition to the revolving credit facility (the "Revolver") provided for under the Credit Agreement. The Term Loan B facility was issued at 99.75% of par value. Since that time, 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. As of December 31, 2024, the Term Loan B outstanding balance was $455,000.

On June 26, 2024, Griffon further amended its Credit Agreement to favorably reprice the Term Loan B facility. The amendment reduced the margin above Secured Overnight Financing Rate ("SOFR") by 0.25%, eliminated the credit spread adjustment and reduced the SOFR floor from 0.50% to 0%. In connection with the amendment Griffon recognized a $1,700 loss on debt extinguishment primarily consisting of the write-off of unamortized debt issuance costs and original issue discount related to portions of the Term Loan B facility that were repaid and then reborrowed from new lenders. At December 31, 2024, unamortized costs of $5,107 related to existing and new Term Loan B facility lenders will continue to be amortized over the term of the loan.

payments based on a percentage of excess cash flow and certain secured leverage thresholds and a final balloon payment due at maturity. Term Loan B borrowings may generally be repaid without penalty. Once repaid, Term Loan B borrowings may not be reborrowed. 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 that secures borrowings under the Revolver, on an equal and ratable basis. The fair value of the Term Loan B facility approximated $457,275 on December 31, 2024 based upon quoted market prices (Level 1 inputs).

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 ("CDOR") with the Canadian Overnight Repo Rate Average ("CORRA"). The facility accrues interest at CORRA plus 1.3% per annum (4.60% as of December 31, 2024). The revolving facility matured in December 2024. In January 2025, Garant entered into a new CAD 20,000 revolving credit facility. The facility accrues interest at CORRA plus a credit adjustment spread and margin of 1.2%. Garant is required to maintain a certain minimum equity.

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 December 31, 2024, Griffon and its subsidiaries were in compliance with the terms and covenants of all its credit and loan agreements. Net debt to EBITDA (Leverage ratio), a non-GAAP measure, is a key financial measure that is used by management to assess the borrowing capacity of the Company. The Company has defined its net debt to EBITDA leverage ratio as net debt (total principal debt outstanding net of cash and equivalents) divided by the sum of trailing twelve-month (“TTM”) adjusted EBITDA (as defined above) and TTM stock-based compensation expense. Net Debt to EBITDA, as calculated in accordance with the definition in the Credit Agreement, was 2.4x at December 31, 2024.

Capital Resource Requirements

Griffon's debt requirements include principal on our outstanding debt, most notably our Senior Notes totaling $974,775 payable in 2028 and related annual interest payments of approximately $56,050, a Term Loan B facility maturing in 2029 with an outstanding balance of $455,000 on December 31, 2024 and Revolver maturing in 2028 with an outstanding balance of $59,500. The Term Loan B accrues interest at the Term SOFR plus a spread of 2.25% (6.58% as of December 31, 2024). The Term Loan B facility continues to require 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, and a balloon payment due at maturity. For the Revolver, 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 SOFR loans accrue interest at Term SOFR plus a credit spread adjustment and a margin of 2.00% (6.43% at December 31, 2024); SONIA loans accrue interest at SONIA Base Rate plus a credit spread adjustment and a margin of 2.00% (6.73% at December 31, 2024); and base rate loans accrue interest at prime rate plus a margin of 1.00% (8.50% at December 31, 2024).

Customers

A small number of customers account for, and are expected to continue to account for, a substantial portion of Griffon’s consolidated revenue. For the three months ended December 31, 2024, our largest customer, The Home Depot, represented 10% of Griffon’s consolidated revenue, 9% of HBP’s revenue and 12% of CPP's revenue.

No other customer are expected to exceed 10% of consolidated revenue. Future operating results will continue to depend substantially on the success of Griffon’s largest customers and our ongoing relationships with them. Orders from these customers are subject to change and may fluctuate materially. The loss of all or a portion of the volume from any one of these customers could have a material adverse impact on Griffon’s liquidity and results of operations.

CRITICAL ACCOUNTING POLICIES

The preparation of Griffon’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires the use of estimates, assumptions, judgments and subjective interpretations of accounting principles that have an impact on assets, liabilities, revenue and expenses. These estimates can also affect supplemental information contained in public disclosures of Griffon, including information regarding contingencies, risk and its financial condition. These estimates, assumptions and judgments are evaluated on an ongoing basis and based on historical experience, current conditions and various other assumptions, and form the basis for estimating the carrying values of assets and liabilities, as well as identifying and assessing the accounting treatment for commitments and contingencies. Actual results may materially differ from these estimates. There have been no changes in Griffon’s critical accounting policies from September 30, 2024.

Griffon’s significant accounting policies and procedures are explained in the Management Discussion and Analysis section in the Annual Report on Form 10-K for the year ended September 30, 2024. In the selection of the critical accounting policies, the objective is to properly reflect the financial position and results of operations for each reporting period in a consistent manner that can be understood by the reader of the financial statements. Griffon considers an estimate to be critical if it is subjective and if changes in the estimate using different assumptions would result in a material impact on the financial position or results of operations of Griffon.

RECENT ACCOUNTING PRONOUNCEMENTS

The FASB issues, from time to time, new financial accounting standards, staff positions and emerging issues task force consensus. See the Notes to Condensed Consolidated Financial Statements for a discussion of these matters.

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q, especially “Management’s Discussion and Analysis”, contains certain “forward-looking statements” within the meaning of the Securities Act, the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995. Such statements relate to, among other things, income (loss), earnings, cash flows, revenue, changes in operations, operating improvements, the industries in which Griffon Corporation (the “Company” or “Griffon”) operates and the United States and global economies. Statements in this Form 10-Q that are not historical are hereby identified as “forward-looking statements” and may be indicated by words or phrases such as “anticipates,” “supports,” “plans,”

Table of Contents

“projects,” “expects,” “believes,” "achieves", “should,” “would,” “could,” “hope,” “forecast,” “management is of the opinion,” “may,” “will,” “estimates,” “intends,” “explores,” “opportunities,” the negative of these expressions, use of the future tense and similar words or phrases. Such forward-looking statements are subject to inherent risks and uncertainties that could cause actual results to differ materially from those expressed in any forward-looking statements. These risks and uncertainties include, among others: current economic conditions and uncertainties in the housing, credit and capital markets; Griffon’s ability to achieve expected savings and improved operational results from cost control, restructuring, integration and disposal initiatives (including the expanded CPP global outsourcing strategy announced in May 2023); the ability to identify and successfully consummate, and integrate, value-adding acquisition opportunities; increasing competition and pricing pressures in the markets served by Griffon’s operating companies; the ability of Griffon’s operating companies to expand into new geographic and product markets, and to anticipate and meet customer demands for new products and product enhancements and innovations; increases in the cost or lack of availability of raw materials such as steel, resin and wood, components or purchased finished goods, including any potential impact on costs or availability resulting from tariffs; changes in customer demand or loss of a material customer at one of Griffon’s operating companies; the potential impact of seasonal variations and uncertain weather patterns on certain of Griffon’s businesses; political events or military conflicts that could impact the worldwide economy; a downgrade in Griffon’s credit ratings; changes in international economic conditions including inflation, interest rate and currency exchange fluctuations; the reliance by certain of Griffon’s businesses on particular third party suppliers and manufacturers to meet customer demands; the relative mix of products and services offered by Griffon’s businesses, which impacts margins and operating efficiencies; short-term capacity constraints or prolonged excess capacity; unforeseen developments in contingencies, such as litigation, regulatory and environmental matters; Griffon’s ability to adequately protect and maintain the validity of patent and other intellectual property rights; the cyclical nature of the businesses of certain of Griffon’s operating companies; possible terrorist threats and actions and their impact on the global economy; effects of possible IT system failures, data breaches or cyber-attacks; the impact of pandemics, such as COVID-19, on the U.S. and the global economy, including business disruptions, reductions in employment and an increase in business and operating facility failures, specifically among our customers and suppliers; Griffon’s ability to service and refinance its debt; and the impact of recent and future legislative and regulatory changes, including, without limitation, changes in tax laws. Additional important factors that could cause the statements made in this Quarterly Report on Form 10-Q or the actual results of operations or financial condition of Griffon to differ are discussed under the caption “Item 1A. Risk Factors” and “Special Notes Regarding Forward-Looking Statements” in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2024. Such statements reflect the views of the Company with respect to future events and are subject to these and other risks, as previously disclosed in the Company's Securities and Exchange Commission filings. Readers are cautioned not to place undue reliance on these forward-looking statements. These forward-looking statements speak only as of the date made. Griffon undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

Item 3 - Quantitative and Qualitative Disclosures About Market Risk

Griffon’s business activities necessitate the management of various financial and market risks, including those related to changes in interest rates, foreign currency rates and commodity prices.

Interest Rates

Griffon’s exposure to market risk for changes in interest rates relates primarily to variable interest rate debt and investments in cash and equivalents.

Griffon's amended and restated Credit Agreement references a benchmark rate with SONIA or SOFR. In addition, certain other of Griffon’s credit facilities have BBSY (Bank Bill Swap Rate) and CORRA (Canadian Overnight Repo Rate Average) (based variable interest rate. Due to the current and expected level of borrowings under these facilities, a 100 basis point change in SONIA, SOFR, BBSY, or CORRA would not have a material impact on Griffon’s results of operations or liquidity.

Foreign Exchange

Griffon conducts business in various non-US countries, primarily in Canada, Australia, the United Kingdom, Ireland, New Zealand and China; therefore, changes in the value of the currencies of these countries affect Griffon's financial position and cash flows when translated into US Dollars. Griffon has generally accepted the exposure to exchange rate movements relative to its non-US operations. Griffon may, from time to time, hedge its currency risk exposures. A change of 10% or less in the value of all applicable foreign currencies would not have a material effect on Griffon’s financial position and cash flows.

Table of Contents

Item 4 - Controls and Procedures

Management's Quarterly Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of Griffon’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), Griffon’s disclosure controls and procedures, as defined by Exchange Act Rule 13a-15(e) and 15d-15(e), were evaluated as of the end of the period covered by this report. Based on that evaluation, Griffon’s CEO and CFO concluded that Griffon’s disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There were no changes in the Griffon’s internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) that occurred during the three months ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, Griffon’s internal control over financial reporting.

Limitations on the Effectiveness of Controls

Griffon believes that a control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all controls issues and instances of fraud, if any, within a company have been detected. Griffon’s disclosure controls and procedures, as defined by Exchange Act Rule 13a-15(e) and 15d-15(e), are designed to provide reasonable assurance of achieving their objectives.

PART II - OTHER INFORMATION

Item 1 Legal Proceedings

None.

Item 1A Risk Factors

In addition to the other information set forth in this report, carefully consider the factors in Item 1A to Part I in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2024, which could materially affect Griffon’s business, financial condition or future results. The risks described in Griffon’s Annual Report on Form 10-K are not the only risks facing Griffon. Additional risks and uncertainties not currently known to Griffon or that Griffon currently deems to be immaterial also may materially adversely affect Griffon’s business, financial condition and/or operating results.

Exhibit 19.1

GRIFFON CORPORATION

POLICY ON INSIDER TRADING

In the course of conducting the business of Griffon Corporation (the "Company"), we may come into possession of material information about the Company or other entities that is not available to the investing public ("material non-public information"). You must maintain the confidentiality of material non-public information and may not use it in connection with the purchase or sale of Griffon Securities (as defined below) or the securities of any other entity to which the information relates. The Company has adopted this Policy on Insider Trading (this “Policy”) in order to ensure compliance with the law and to avoid even the appearance of improper conduct by anyone associated with the Company. We have all worked hard to establish the Company’s reputation for integrity and ethical conduct, and we are all responsible for preserving and enhancing this reputation. There are no exceptions to this Policy, except as specifically noted herein.

Applicability

The restrictions set forth in this Policy apply to all Company officers, directors and employees, including directors, officers and employees of the Company’s subsidiaries, wherever located, and to their spouses, minor children, adult family members sharing the same household and any other person over whom the officer, director or employee exercises substantial influence or control over his, her or its securities trading decisions. This Policy also applies to any trust or other estate in which a director, officer or employee has a substantial beneficial interest or as to which he or she serves as trustee or in a similar fiduciary capacity. The Company may also determine that other persons should be subject to this Policy, such as contractors or consultants who have access to material non-public information.

Each individual is responsible for making sure that he or she complies with this Policy, and that any family member, household member or entity whose transactions are subject to this Policy also complies with this Policy. In all cases, the responsibility for determining whether an individual is in possession of material non-public information rests with that individual, and any action on the part of the Company, Griffon’s General Counsel or any other employee or director pursuant to this Policy (or otherwise) does not in any way constitute legal advice or insulate an individual from liability under applicable securities laws.

To avoid even the appearance of impropriety, additional restrictions on trading Griffon securities apply to directors, officers and certain designated employees. These policies are set forth in the Company's Addendum to Insider Trading Policy that applies to directors, officers, and certain designated employees of the Company who have access to material non-public information about the Company on a periodic basis. The Company will notify you if you are subject to the Addendum. The Addendum generally prohibits those covered by it from trading in Griffon securities during blackout periods and requires pre-clearance for all transactions in Griffon securities.

Inside Information

Company policy and the laws of the United States and many other countries strictly prohibit any director, officer or employee of the Company, whenever and in whatever capacity employed, from trading Company securities (including equity securities, convertible securities, options, bonds, and derivatives thereof) (“Griffon Securities”) while in possession of “inside information” about the Company. Inside information is any material, non-public information about a company.

If you become aware of any inside information, you may not execute any trade in Griffon securities and you should treat the information as strictly confidential. This prohibition applies to Griffon securities as well as the securities of any other company, including but not limited to customers, suppliers, vendors and distributors of the Company, about which you acquire inside information in the course of your duties for the Company. It also applies to transactions for any Company account, employee account or account over which the employee has investment discretion. You are responsible for reviewing this Policy and ensuring that your actions do not violate it.

Material, Non-Public Information

As noted above, it is illegal and a violation of Company policy to trade securities while aware of material, non-public information.

What is Material Information?

Under Company policy and United States law, information is material if:

•there is a substantial likelihood that a reasonable investor would consider the information important in determining whether to trade in a security; or

•the information, if made public, likely would affect the market price of a company's securities.

Information may be material even if it relates to future, speculative or contingent events and even if it is significant only when considered in combination with publicly available information. Material information can be positive or negative.

Depending on the facts and circumstances, information that could be considered material includes, but is not limited to:

•earnings announcements or estimates, or changes to previously released announcements or estimates;

•other unpublished financial results;

•significant dividend increases or decreases;

•write-downs and additions to reserves (i.e., for bad debts);

•expansion or curtailment of operations;

•new products, inventions or discoveries;

•major litigation or government actions;

•significant cybersecurity incidents, such as a data breach, or any other significant disruption in the Company’s operations;

•possible acquisitions, divestitures or joint ventures;

•changes in analyst recommendations or debt ratings;

•restructurings and recapitalizations;

•anticipated public offerings of securities;

•extraordinary management developments;

•extraordinary borrowing; and

•liquidity problems.

What is Non-Public Information?

Information is considered to be non-public unless it has been adequately disclosed to the public, which means that the information must be publicly disseminated and sufficient time must have passed for the securities markets to digest the information.

It is important to note that information is not necessarily public merely because it has been discussed in the press, which will sometimes report rumors. You should presume that information is non-public unless you can point to its official release by the Company in at least one of the following ways:

•public filings with securities regulatory authorities;

•issuance of press releases; or

•meetings with members of the press and the public.

You may not attempt to “beat the market” by trading simultaneously with, or shortly after, the official release of material information. Although there is no fixed period for how long it takes the market to absorb information, out of prudence a person aware of material, non-public information should refrain from any trading activity for approximately one full trading day following its official release; shorter or longer waiting periods might be warranted based upon the liquidity of the security and the nature of the information.

Notwithstanding these timing guidelines, it is illegal for you to trade while in possession of material, non-public information, including situations in which you are aware of major developments that have not yet been publicly announced by the issuer.

What Transactions are covered by this Policy?

Trading includes the purchase and sale and, as applicable, the exercise, of any type of Griffon Security.

Twenty-Twenty Hindsight

If securities transactions ever become the subject of scrutiny, they are likely to be viewed after-the-fact with the benefit of hindsight. As a result, before engaging in any transaction you should carefully consider how the transaction may be construed in the bright light of hindsight. If you have any questions or uncertainties about this Policy or a proposed transaction, please ask Griffon’s General Counsel.

“Tipping” Material, Non-Public Information Is Prohibited

In addition to trading while in possession of material, non-public information, it is illegal and a violation of this Policy, as well as the Company’s Code of Business Conduct and Ethics, to convey such information to another ("tipping") if you know or have reason to believe that the person will misuse such information by trading in securities or passing such information to others who are likely to trade. This applies regardless of whether the "tippee" is related to the insider or is an entity, such as a trust or a corporation, and regardless of whether you receive any monetary benefit from the tippee.

Trading on or conveying material, non-public information may also breach contractual obligations assumed by the Company to or on behalf of Company customers. Apart from contractual remedies (such as damages and injunctions), severe, and possibly irreparable, reputational damage to the Company can result from trading on, tipping or other improper use of material, non-public information.

Avoid Speculation

Those subject to this Policy may not trade in options, warrants, puts and calls or similar instruments on Griffon securities or sell Griffon securities "short." In addition, you may not pledge or hold Griffon securities in margin accounts or engage in hedging or monetization transactions. Investing in Griffon securities provides an opportunity to share in the future growth of the Company; however, this does not mean short-range speculation based on fluctuations in the market. Such activities may put the personal gain of the director, officer or employee in conflict with the best interests of the Company and its shareholders. Anyone may, of course, exercise any options granted to them by the Company and, subject to the restrictions discussed in this Policy and other applicable Company policies, sell shares acquired through exercise of options.

Trading Plans

Notwithstanding the prohibition against insider trading, Rule 10b5-1 of the Securities Exchange Act of 1934 ("Rule 10b5-1") permits employees to trade in Griffon securities, regardless of their awareness of inside information, if the transaction is made pursuant to a pre-arranged written trading plan ("Trading Plan") that was entered into when the employee was not in possession of material, non-public information and complies with the requirements of Rule 10b5-1. An employee who wishes to enter into a Trading Plan must submit the Trading Plan to the Company’s General Counsel for approval prior to adoption of the Trading Plan. Trading Plans will be approved at the discretion of the Company. Trading Plans may not be adopted when the employee is in possession of material non-public information about the Company. An employee may amend or replace his or her Trading Plan only during periods when trading is permitted in accordance with this Policy and, once a Trading Plan is adopted, the person must not exercise any influence over the amount of securities to be traded, the price at which securities are to be traded or the date(s) on which securities are to be traded. Trading Plans must either specify the amount, pricing and timing of transactions in advance or delegate discretion on these matters to an independent third party. Trading Plans must also include a cooling-off period before trading can commence. For directors or officers, this period ends on the later of 90 days after the adoption of the Trading Plan or two business days following the disclosure of the Company’s financial results in a periodic report filed with the U.S. Securities and Exchange Commission for the fiscal quarter in which the Trading Plan was adopted (but in any event the required cooling-off period will not be longer than 120 days after adoption of the Trading Plan). For persons other than directors or officers, the cooling off period ends 30 days following the adoption or modification of a Trading Plan. A person may not enter into overlapping Trading Plans (subject to certain exceptions), and may only enter into one single-trade Trading Plan during any 12-month period (again, subject to certain exceptions). Directors and officers must include a representation in their Trading Plan stating that: (i) they are not aware of any material non-public information; and (ii) they are adopting the Trading Plan in good faith and not as part of a plan or scheme to evade the prohibitions in Rule 10b-5. All persons entering into a Trading Plan must act in good faith with respect to that Trading Plan.

Reporting Violations/Seeking Advice

You should refer suspected violations of this policy to Griffon’s General Counsel. In addition, if you:

•receive material, non-public information that you are not authorized to receive or that you do not legitimately need to know to perform your employment responsibilities, or

•receive confidential information and are unsure if it is within the definition of material, non-public information or whether its release might be contrary to a fiduciary or other duty or obligation,

you should not share it with anyone. To seek advice about what to do under those circumstances, contact Griffon’s General Counsel. Consulting your legal colleagues can have the effect of exacerbating the problem. Containment of the information, until the legal implications of possessing it are determined, is critical.

Penalties for Violations of the Insider Trading Policy and Laws

In the United States and many other countries, the personal consequences of illegally trading securities while in possession of material, non-public information can be quite severe. Certain securities laws provide that an individual is subject to possible imprisonment and significant fines. These laws apply to all employees – not just officers and directors. Subject to applicable law, Company employees who violate this Policy may also be subject to discipline by the Company, up to and including termination of employment.

If you are located or engaged in dealings outside the United States, be aware that laws regarding insider trading and similar offenses differ from country to country. Employees must abide by the laws in the country in which the employee is located. However, you are required to comply with this Policy even if local law is less restrictive. If you believe that a local law conflicts with this Policy, you must consult Griffon’s General Counsel.

GRIFFON CORPORATION

ADDENDUM TO POLICY ON

INSIDER TRADING

INTRODUCTION

This Addendum is in addition to and supplements the Griffon Corporation Policy on Insider Trading (the “Policy on Insider Trading”). This Addendum applies to directors, officers and certain designated employees of Griffon Corporation (“Griffon” or the "Company") and its subsidiaries who have access to material non-public information about the Company. This Addendum does not apply to the Company or its Employee Stock Ownership Plan. The positions of the covered persons subject to this Addendum are listed on attached Schedule A. The Company’s Board of Directors or Chief Executive Officer may from time to time designate other positions that are subject to this Addendum; and Schedule A will be amended from time to time as necessary to reflect such changes or the resignation or change of status of any individual.

Please read this Addendum carefully. When you have completed your review, please sign the attached acknowledgment form and return it to Griffon’s General Counsel.

Contact Griffon’s General Counsel if at any time you have questions about this Addendum or its application to a particular situation.

GENERAL RULES

In general terms, the law and Company policy prohibit:

X Buying or selling Company securities (including equity securities, convertible securities, options, bonds, and derivatives thereof) (“Company Securities”), or in some cases the securities of other companies, while in possession of material non-public information. In order to avoid even the appearance of impropriety, the Company's policy is to require pre-clearance of all transactions in Company Securities by those subject to this Addendum (as described in more detail below), and to prohibit any transactions in Company Securities by those subject to this Addendum during certain designated blackout periods, as detailed below.

X Disclosing material non-public information to outsiders, including family members and others (tipping), who then trade in Company Securities or the securities of another company while in possession of that information.

X Retaining "short-swing profits" earned by directors or certain officers through trading in the Company Securities that are equity securities (“Company Equity Securities”), whether or not in possession of material non-public information. Any such profits, which generally involve a purchase and sale or a sale and purchase (or any number of these transactions) within any period of less than six months, must be disgorged to the Company.

X The sale of any Company Securities without complying with all the requirements of Rule 144 under the Securities Act of 1933 (the "Securities Act"), if applicable. This Rule, also described in more detail later in this Addendum, has detailed reporting requirements, and strict limitations and requirements regarding:

X the number of shares that may be sold during an established period of time;

X for certain securities, the length of time for which they must be held before they are sold;

X the availability of publicly available information about the Company; and

X the manner of sale.

X Answering questions or providing information about the Company and its affairs to Company outsiders unless you are specifically authorized to do so, or it is a regular part of the duties of your position.

In addition, Company Directors and those officers designated by the Board of Directors as Section 16 Officers ("Section 16 Officers") are required to file a number of forms with the Securities and Exchange Commission (the "SEC") in connection with various events, which include:

X An initial statement regarding beneficial ownership of Company Equity Securities, usually filed at the time of becoming a Director or Section 16 Officer, regardless of actual ownership of such securities (Form 3).

X Statements of changes of beneficial ownership of securities of the Company, or derivatives thereof, to be filed within two business days after any such change (Form 4).

X Annual statement of beneficial ownership of securities, filed within 45 days of the end of the Company's fiscal year with respect to certain securities transactions not earlier reported (Form 5).

Griffon’s General Counsel will provide information to its Directors and Section 16 Officers concerning these requirements and the required filings of these Forms, and will offer to facilitate the filing of these forms on behalf of each Director and Section 16 Officer. However, each Section 16 Officer and Director bears legal responsibility for complying with these requirements and should consult with Griffon’s General Counsel regarding any question or clarifications.

TRADING WHILE AWARE OF

MATERIAL NON-PUBLIC INFORMATION

You must maintain the confidentiality of material non-public information and may not trade in Company Securities, or the securities or derivatives of any other entity to which the information relates, until the information has been made public. The Policy on Insider Trading describes in detail the prohibition against trading while aware of material non-public information, which you must read and follow.

PRE-CLEARANCE PROCEDURES

Those subject to this Addendum, and their spouses, minor children, adult family members sharing the same household, and any other person the securities trading decisions over which the individual exercises substantial influence or control (collectively, "Family Members"), may not engage in any transaction involving Company Securities (including gifts, loans, contributions to a trust, or any other transfers) without first obtaining pre-clearance of the transaction from Griffon’s General Counsel. Notwithstanding the foregoing, pre-clearance is not required for any trades made pursuant to a pre-arranged 10b5-1 Trading Plan adopted in accordance with the requirements of the Policy on Insider Trading or for transactions or trades with the Company, including, without limitation, the withholding of shares by the Company to satisfy tax withholding obligations in connection with the vesting of restricted shares. Each proposed transaction will be evaluated to determine if it raises insider trading concerns or other concerns under federal laws and regulations. Any advice will relate solely to the restraints imposed by law and will not constitute advice regarding the investment aspects of any transaction. Clearance of a transaction is valid only for a 72-hour period. If the transaction order is not placed within that 72-hour period, clearance of the transaction must be requested again. If clearance is denied, the fact of such denial must be kept confidential by the person requesting such clearance. Clearance does not relieve a person of his or her legal obligation to refrain from trading while in possession of material non-public information.

BLACKOUT PERIOD

From time to time, an event may occur that is material to the Company and is known by only a limited group of officers and/or directors. The existence of an event-specific blackout will not be announced. If, however, a person whose trades are subject to pre-clearance requests permission to trade in Company Securities during an event-specific blackout, Griffon’s General Counsel will inform the requesting person of the existence of a blackout period, without disclosing the reason for the blackout. Any person made aware of the existence of an event-specific blackout should not disclose the existence of the blackout to any other person.

MARGIN ACCOUNTS AND PLEDGING COMPANY SECURITIES

The Company prohibits those subject to this Addendum from purchasing Company Securities on margin, holding Company Securities in a margin account or pledging Company Securities. Securities held in a margin account may be sold by the broker without the customer’s consent if the customer fails to meet a margin call. Likewise, securities pledged to a bank or financial institution may be sold without the customer’s consent if the customer fails to repay the obligation secured by the pledge. As a result, such sales may occur at a time when an employee or a director has material, non-public information or is otherwise not permitted to trade in Company Securities.

HEDGING TRANSACTIONS

The Company prohibits those subject to this Addendum from engaging in hedging or monetization transactions with respect to Company Securities, such as zero-cost collars and forward sale contracts, which allow an employee to lock in all or a portion of the value of a security, often in exchange for all or part of the potential for upside appreciation in such security. These transactions allow the employee, director or other individual to continue to own the Company Security, but without the full risks and rewards of ownership. When that occurs, the employee, director or other individual may no longer have the same objectives as the Company’s other shareholders; therefore, such transactions are prohibited.

REPORTING AND FORM FILING REQUIREMENTS

Under Section 16(a) of the Securities Exchange Act of 1934 (the "Exchange Act"), directors and certain executive officers (the “Section 16 Officers”) of the Company must file forms with the SEC when they engage in certain transactions involving Company Equity Securities. In this context, in addition to basic traditional equity interests such as common stock, "Company Equity Securities" also includes any securities that are exchangeable for or convertible into, or that derive their value from, a Company Equity Security. These other securities are known as derivative securities and include options, warrants, convertible securities and stock appreciation rights.

Form 3: Initial Beneficial Ownership Statement. A person who becomes a director or Section 16 Officer of the Company must file a Form 3 within ten days of becoming a director or Section 16 Officer, even if the director or Section 16 Officer is not an owner of Company Equity Securities at the time. The Form 3 must disclose the director's or Section 16 Officer's ownership of any Company Equity Securities the director or Section 16 Officer owns immediately prior to assuming office.

Form 4: Changes of Beneficial Ownership Statement. As long as a person remains a director or Section 16 Officer, and under certain circumstances for up to six months after a person no longer holds such a position with the Company, a Form 4 must be filed before 10:00 p.m. on the second business day following the day that there is a change in the number of Company Equity Securities held from that previously reported to the SEC. There are exceptions to this requirement for a limited class of employee benefit plan transactions.

Form 5: Annual Beneficial Ownership Statement. A Form 5 must be filed with the SEC by any individual who served as a director or Section 16 Officer of the Company during any part of the Company's fiscal year to report: (1) all reportable transactions in Company Equity Securities exempt from the Form 4 filing requirement, or unreported transactions of less than $10,000; (2) all transactions that should have been reported on a Form 4 during the last fiscal year but were not; and (3) with respect to an individual's first Form 5, all transactions which should have been reported but were not for the last two fiscal years.

A Form 5 need not be filed if all transactions otherwise reportable have been previously reported. If required, Form 5 must be filed within 45 days after the end of the Company's fiscal year, which is November 14, or the first business day thereafter.

Any questions concerning whether a particular transaction will require filing one of these Forms, or how or when they should be completed, should be asked of Griffon’s General Counsel. The Company must disclose in its Annual Report on Form 10-K and in its Proxy Statement any delinquent filings of Forms 3, 4 or 5 by directors and Section 16 Officers, and must post on its website, by the end of the business day after filing with the SEC, any Forms 3, 4 and 5 relating to Company Equity Securities.

Reporting Exemptions for Certain Employee Benefit Plan Transactions

Rule 16b-3 under the Exchange Act provides exemptions for director and Section 16 Officer reporting of certain employee benefit plan events on Forms 4 and 5, including certain routine non-volitional transactions under tax-conditioned thrift, stock purchase and excess benefit plans.

A transaction that results only in a change in the form of a person's beneficial ownership is also exempt from reporting. An exempt "change in the form of beneficial ownership" would include, for example, a distribution of benefit plan securities to an insider participant where the securities were previously attributable to the insider. Exercises or conversions of derivative securities would not, however, be considered mere changes in beneficial ownership and would be reportable.

The vesting of most stock options, restricted stock and stock appreciation rights is also not subject to the Form 4 and Form 5 reporting requirements.

Short-Swing Trading Profits

In order to discourage directors and officers from profiting through short-term trading transactions in Company Equity Securities, Section 16(b) of the Exchange Act requires that any "short-swing profits" be disgorged to the Company. (This is in addition to the Form reporting requirements described above.)

"Short-swing profits" are profits that result from any purchase and sale, or sale and purchase, of Company Equity Securities within a six-month period unless there is an applicable exemption for either transaction. It is important to note that this rule applies to

any matched transactions in Company Equity Securities, not only a purchase and sale or sale and purchase of the same shares, or even of the same class of securities. Furthermore, pursuant to the SEC's rules, the "statutory profit" is determined so as to maximize the amount that the director or Section 16 Officer must disgorge, and this amount may not be offset by any losses realized.

Short-swing Exemptions for Certain Reinvestment and

Employee Benefit Plan Transactions

As indicated, to come within the short-swing rules, a purchase and sale (or sale and purchase) within a six-month period are matched to determine the amount of profit (if any). Rule 16b-3 has carved out a few exceptions to what constitutes a "purchase" for these matching purposes.

Under this Rule certain transactions involving acquisitions of equity securities under employee benefit plans are not counted as "purchases" for short-swing purposes, provided that the benefit plan transaction meets various statutory requirements.

The Griffon Employee Stock Ownership Plan meets these requirements, and therefore an acquisition of equity securities under that plan generally speaking is not a "purchase" for short-swing purposes.

Prohibition Against Short-sales

Directors and Section 16 Officers are prohibited from making "short sales" of Company Equity Securities. A short sale has occurred if the seller: (1) does not own the securities sold at the time of executing the sale transaction; or (2) does own the securities sold, but does not deliver them within 20 days or place them in the mail within 5 days of the sale.

LIMITATIONS AND REQUIREMENTS ON

RESALES OF COMPANY SECURITIES

Under the Securities Act, directors and certain officers who are considered to be “affiliates” under Rule 144 who wish to resell their Company securities must comply with the requirements of Rule 144, or risk being required to register the securities under the Securities Act. "Securities" under Rule 144 (unlike under Section 16) are broadly defined to include all securities, not just equity securities. Therefore, the Rule 144 requirements apply not only to common and preferred stock, but also to bonds, debentures and any other form of security. Also, the requirements of Rule 144 apply whether or not the securities to be resold were previously registered under the Securities Act, except for the minimum holding period (which applies only to securities which were not registered under the Securities Act).

The relevant provisions of Rule 144 as they apply to resales by directors and officers are as follows:

1.Current public information. There must be adequate current public information available regarding the Company. This requirement is satisfied only if the

Company has filed all reports required by the Exchange Act during the twelve months preceding the sale.

2.Manner of sale. The sale of Company shares by a director or officer must be made in an open market transaction through a broker at the prevailing market price for no more than the usual and customary brokerage commission. Furthermore, the broker may not solicit or arrange for the solicitation of customers to purchase the shares.

3.Number of shares which may be sold. The amount of securities that a director or officer may sell in a three-month period is limited to the greater of:

a.one percent of the outstanding shares of the Company, or

b.the average weekly reported trading volume in the four calendar weeks preceding the transactions.

4.Notice of proposed sale. If the amount of securities proposed to be sold by a director or officer during any three-month period exceeds 5,000 shares or has an aggregate sale price in excess of $50,000, the officer or director must file a notice of sale with the SEC on Form 144 prior to, or concurrently with, the placing of the order to sell securities.

5.Holding Periods. Any Company Securities acquired directly or indirectly from the Company in a transaction that was not registered with the SEC under the Securities Act (restricted securities) must be held for six months prior to reselling such securities. There is no statutory minimum holding period for securities which were registered under the Securities Act or acquired in an open-market transaction.

In certain situations (e.g., securities acquired through stock dividends, splits or conversions), "tacking" is permitted-- that is, the new securities will be deemed to have been acquired at the same time as the original securities.

NOTIFICATION TO BROKERS

In order to facilitate compliance with this Addendum, each director and Section 16 Officer is required to notify each securities broker, asset manager and investment advisor retained by such person, and any other professional advisor or agent that could engage in a securities transaction on behalf of such person, that such person is a director or officer of Griffon and is required to (i) obtain pre-clearance from Griffon’s General Counsel before engaging in any transaction in Company Securities, and (ii) file forms under Section 16(a) of the Exchange Act to report most transactions in Company Equity Securities. Such notification must be in the form of the letter attached as Schedule B, and a copy of each such letter, when sent, should be provided to Griffon’s General Counsel.

POTENTIAL PENALTIES FOR VIOLATIONS OF LAW

AND THIS ADDENDUM

The seriousness of securities law violations is reflected in the penalties that may result. A director's resignation may be sought, or an officer or employee will be subject to possible Company disciplinary action up to and including termination of employment. In addition, both the Company itself and individual directors, officers or employees may be subjected to both criminal and civil liability which, for individuals, can include a prison sentence.

QUESTIONS

Because of the technical nature of some aspects of the federal securities laws, you should review this material carefully and contact Griffon’s General Counsel prior to engaging in any transaction in Company Securities which might be in conflict with the securities law and this Addendum.

ACKNOWLEDGEMENT

All directors, officers and other employees subject to the procedures set forth in this Addendum must acknowledge their understanding of, and intent to comply with, the Policy on Insider Trading and this Addendum on the form attached to this Addendum.

[name of broker or other securities professional]

[address]

Dear [name of contact at broker]_:

Please be advised that I am [a director] [the [insert officer title]] of Griffon Corporation (“Griffon”). Griffon’s common stock is listed on, and traded on, the New York Stock Exchange. Griffon has adopted a Policy on Insider Trading (the “Policy”), as well as an Addendum to the Policy (the “Addendum”) that supplements the Policy and applies to directors, officers and certain other key employees. Pursuant to the Addendum, I am required to provide this letter to you.

The Addendum requires that, before I (or any of my spouse, minor children, adult family members sharing the same household, or any other person or entity the securities trading decisions over which I exercise substantial influence or control), engage in any transaction involving Griffon securities, I obtain “pre-clearance” regarding such transaction from Griffon’s General Counsel. Therefore, I am instructing you that, before you effect any transaction on my behalf (or on behalf of any of the other persons or entities referenced above) in Griffon common stock, or in any other Griffon security, you confirm with Griffon’s General Counsel that I have obtained such pre-clearance.

The Addendum also prohibits me from purchasing Griffon securities on margin, holding Griffon securities in a margin account or pledging company securities to secure debt; and prohibits me from engaging in hedging or monetizing transactions, such as zero-cost collars and forward sale contracts. I would appreciate your assistance to ensure that I remain in compliance with these prohibitions contained in the Addendum.

Finally, the Addendum makes it clear that I am required to file certain forms with the Securities and Exchange Commission (generally a “Form 4”) when I (or any of the persons or entities referenced above) engage in any transaction involving Griffon common stock, subject to limited exceptions. I have executed a power of attorney authorizing Griffon’s General Counsel to file these forms on my behalf. Therefore, anytime you effect such a transaction in Griffon common stock on my behalf (or on behalf of any of the persons or entities referenced above), you are authorized, and directed, to provide the details to Griffon’s General Counsel as soon as possible so that the appropriate form can be timely filed on my behalf. Please note that, since a Form 4 is generally required to be filed within two business days after any transaction in Griffon common stock, time is of the essence when providing the details regarding any such transaction.

The name and contact information of Griffon’s General Counsel is as set forth below; should this information change, I will promptly notify you.

Seth L. Kaplan

Please let me know if you have any questions.

[name of Director or Section 16 Officer]

DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	Dec. 31, 2024
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 divestitures. As long-term investors, we intend to continue to grow and strengthen our existing businesses, and to diversify further through investments in our businesses and acquisitions. 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 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, 2024, 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, 2024 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2024. 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, assumptions 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	3 Months Ended
FAIR VALUE MEASUREMENTS	Dec. 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 December 31, 2024, the fair values of Griffon’s 2028 Senior Notes and Term Loan B facility approximated $950,406 and $457,275, respectively. Fair values were based upon quoted market prices (level 1 inputs). Insurance contracts with values of $4,858 at December 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 other assets on the Condensed 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 December 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 December 31, 2024, Griffon had $43,500 of Australian Dollar contracts at a weighted average rate of $1.47 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 $3,844 ($2,690, net of tax) at December 31, 2024. Upon settlement, gains of $955 were recorded in COGS during the three months ended December 31, 2024. All contracts expire in 30 to 150 days. At December 31, 2024, Griffon had $33,500 of Chinese Yuan contracts at a weighted average rate of $7.08 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 $1,043 ($762, net of tax) at December 31, 2024. Upon settlement, losses of $220 were recorded in COGS during the three months ended December 31, 2024. All contracts expire in 3 to 304 days. At December 31, 2024, Griffon had $10,335 of Canadian Dollar contracts at a weighted average rate of $1.35. The contracts, which protect Canadian operations from currency fluctuations for U.S. Dollar based purchases, do not qualify for hedge accounting. For the three months ended December 31, 2024, fair value gains of $242 were recorded to Other liabilities and to Other income for the outstanding contracts, based on similar contract values (level 2 inputs). Realized gains of $46 were recorded in Other income during the three months ended December 31, 2024 for all settled contracts. All contracts expire in 30 to 269 days.

REVENUE	3 Months Ended
REVENUE	Dec. 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, 2024. See Note 13 - Reportable Segments for revenue from contracts with customers disaggregated by end markets, segments and geographic location.

ACQUISITIONS	Dec. 31, 2024
Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
ACQUISITIONS	ACQUISITIONS Griffon continually evaluates potential acquisitions that either 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 business acquisitions are included in Griffon’s consolidated financial statements from the date of acquisition. On July 1, 2024, Griffon announced that its subsidiary, The AMES Companies, Inc., ("AMES") expanded the scope of its Australian operations by acquiring substantially all of the assets of Pope, a leading Australian provider of residential watering products, from the Toro Company (NYSE:TTC) for a purchase price of approximately AUD 21,800 (approximately $14,500) in cash. The purchase price was preliminarily allocated to inventory of AUD 16,581 (approximately $11,051), goodwill of AUD 2,225 (approximately $1,483) and acquired intangibles, net of deferred taxes, of AUD 2,940 (approximately $1,960), which was assigned to the CPP segment, and is not deductible for income tax purposes.

Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS Issued but not yet effective accounting pronouncements In October 2023, the Financial Accounting Standards Board ("FASB") issued ASU No. 2023-06, Disclosure Improvements: Amendments - Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The FASB issued the standard to introduce changes to US GAAP that originate in either SEC Regulation S-X or S-K, which are rules about the form and content of financial reports. The provisions of the standard are contingent when the SEC removes the related disclosure provisions from Regulation S-X and S-K. The company does not expect the provisions of the standard to have a material impact on the Company's financial statements and related disclosures. In November 2023, the 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 with the Company's fiscal year 2025. The standard should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements. 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, (2) continuing operations pre-tax income between domestic and foreign, and (3) continuing operations income tax expense by federal, state and foreign. 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 a material impact on its financial position, results of operations, or cash flows. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses. This guidance requires disclosures regarding specific information about certain costs and expenses, including but not limited to, inventory purchases, employee compensation, depreciation, amortization and selling expenses. The guidance is effective for the Company beginning with the Company's fiscal year 2027 and interim reporting periods beginning with our 2028 fiscal year. Implementation of this standard may be applied prospectively or retrospectively. The Company does not expect the adoption of this standard to have a material impact on the Company's financial statements and related disclosures.

COMMITMENTS AND CONTINGENCIES	3 Months Ended
COMMITMENTS AND CONTINGENCIES	Dec. 31, 2024
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 2025. 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. 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. 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. Since 2021, there has been no further action by the EPA or TDEC relating to the Memphis site. 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. 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.

DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION (Policies)	3 Months Ended
	Dec. 31, 2024
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, 2024, 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, 2024 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2024. 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, assumptions 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.
Issued but not yet effective accounting pronouncements	Issued but not yet effective accounting pronouncements In October 2023, the Financial Accounting Standards Board ("FASB") issued ASU No. 2023-06, Disclosure Improvements: Amendments - Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The FASB issued the standard to introduce changes to US GAAP that originate in either SEC Regulation S-X or S-K, which are rules about the form and content of financial reports. The provisions of the standard are contingent when the SEC removes the related disclosure provisions from Regulation S-X and S-K. The company does not expect the provisions of the standard to have a material impact on the Company's financial statements and related disclosures. In November 2023, the 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 with the Company's fiscal year 2025. The standard should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements. 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, (2) continuing operations pre-tax income between domestic and foreign, and (3) continuing operations income tax expense by federal, state and foreign. 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 a material impact on its financial position, results of operations, or cash flows. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses. This guidance requires disclosures regarding specific information about certain costs and expenses, including but not limited to, inventory purchases, employee compensation, depreciation, amortization and selling expenses. The guidance is effective for the Company beginning with the Company's fiscal year 2027 and interim reporting periods beginning with our 2028 fiscal year. Implementation of this standard may be applied prospectively or retrospectively. The Company does not expect the adoption of this standard to have a material impact on the Company's financial statements and related disclosures.
