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 ClosetMaid, LLC ("ClosetMaid") in 2018 and Hunter Fan Company ("Hunter") in January 2022;

and in 2024 we acquired substantially all the assets of Pope, a leading Australian provider of residential watering products.

We strive to provide highly sought-after and differentiated products under well-regarded brands which clearly separate us from our competitors and strengthen our relationships with our customers and those who ultimately use our products.

We have developed a diverse portfolio of product offerings and brands, sold through multiple sales and distribution channels, serving both residential and commercial end customers.

This diversity provides stability to our operations and reduces the effects of external factors such as economic and construction cycles.

In 2026, Griffon announced a series of strategic actions that, when completed, will transition the Company from a diversified industrial conglomerate into a pure-play provider of residential and commercial building products.

The joint venture will be financed through committed debt financing, in addition to the second-lien loan provided by Griffon.

This transaction is subject to customary closing conditions and, after closing, which is expected to occur by June 2026, Griffon’s interest in the joint venture will be accounted for as an equity method investment.

Any gain or loss as the result of this transaction will be determined at closing.

Additionally, Griffon announced the initiation of a comprehensive review of strategic alternatives for its AMES Australia operations and AMES United Kingdom operations.

As a result of these actions, beginning with Griffon’s second quarter 2026 reporting, AMES’ U.S., Canada, Australia, and U.K.

operations, which are currently part of Griffon’s CPP segment, will be reported as discontinued operations.

Furthermore, in connection with these actions, we announced that the remaining reporting unit within the CPP segment, the Hunter Fan Company, will be combined with Griffon’s HBP segment.

This transaction is subject to customary closing conditions and, after closing, which is expected to occur by the end of June 2026, Griffon’s interest in the joint venture will be accounted for as an equity method investment.

As of March 31, 2026, the Company recorded a loss of $22,648 on assets held for sale because the carrying value of the United States ("U.S.") and Canada businesses of the AMES Companies is greater than its estimated fair value less its cost to sell.

Griffon also announced on February 5, 2026 the initiation of a comprehensive review of strategic alternatives for its AMES Australia and United Kingdom ("U.K.") operations.

The strategic process for AMES Australia is active and ongoing and we expect to complete the process by the end of the calendar year.

operations and will liquidate its assets and settle its liabilities.

As a result of these actions, AMES’ U.S., Canada, Australia, and U.K.

Except for certain U.K.

assets and liabilities not held for sale, we classified the assets and liabilities associated with the AMES' U.S., Canada, Australia and U.K.

discontinued operations as held for sale in the Condensed Consolidated Balance Sheets.

assets classified as held for sale relate to inventory and property, plant and equipment that will be sold in liquidation.

Reportable Segments:

• Home and Building Products ("HBP") conducts its operations through Clopay Corporation ("Clopay").

Revenue for the quarter ended December 31, 2025 was $649,088 compared to $632,371 in the prior year quarter, an increase of $16,717, or 3%, primarily due to increased revenue at both HBP and CPP.

Net income was $64,387 or $1.41 per share, compared to $70,851, or $1.49 per share, in the prior year quarter.

The current year quarter results from operations included the following:

– Impact of retirement plan events of $1,609 ($1,224, net of tax, or $0.03 per share);

– Loss from debt extinguishment of $556 ($423, net of tax, or $0.01 per share);

– Discrete and certain other tax provisions, net, of $268 or $0.01 per share.

The prior 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);

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

Excluding these items from the respective quarterly results, net income would have been $66,302, or $1.45 per share in the quarter ended December 31, 2025 compared to $65,873, or $1.39 per share, in the prior year quarter.

Griffon evaluates performance based on adjusted net income and the related adjusted earnings per share, which are non-GAAP measures that exclude the impact of retirement plan events, 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 to adjusted net income and earnings per share to adjusted earnings per share:

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, 2025, the impact of retirement plan events relates to a non-cash charge of $1,609 included in Other, net associated with the establishment of a retiree medical plan.

The Company will recognize a non-cash charge related to such plan of $5,362 ratably over the first 10 months of fiscal 2026.

(2) The tax impact for the above reconciling adjustments from GAAP net income to non-GAAP adjusted net income and the related adjusted 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.

NON-GAAP FINANCIAL MEASURES

Adjusted EBITDA

Griffon uses adjusted EBITDA as a key metric in evaluating performance.

Adjusted EBITDA, a non-GAAP measure, is defined as income before taxes from continuing operations, excluding interest income and expense, depreciation and amortization, strategic review charges, and non-cash impairment charges, as well as other items that may affect comparability, as applicable.

Griffon believes this information is useful to investors.

We track our non-GAAP financial measures to monitor and manage our underlying financial performance.

See reconciliation of adjusted EBITDA to the applicable most comparable GAAP measure, net income, below.

Adjusted EBITDA and adjusted EBITDA margin are key metrics used by management and our Board to assess our financial performance.

Adjusted EBITDA and adjusted EBITDA margin are also frequently used by analysts, investors, and other interested parties to evaluate companies in our industry, when considered alongside other GAAP measures.

We use adjusted EBITDA and adjusted EBITDA margin to supplement GAAP measures of performance to evaluate the effectiveness of our business strategies and to make budgeting decisions, and we use adjusted EBITDA as a significant performance metric in our annual management incentive bonus plan compensation, as well as to compare our performance against other companies using similar measures.

We have presented adjusted EBITDA and adjusted EBITDA margin solely as supplemental disclosures because we believe they allow for a more complete analysis of results of operations and assist investors and analysts in comparing our operating performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance, such as depreciation and amortization, interest expense, net, income tax provision (benefit), (gain) loss on sale and disposal of property and equipment, restructuring charges, strategic retention costs, and intangible impairment.

Adjusted EBITDA and adjusted EBITDA margin are non-GAAP financial measures and should not be considered as alternatives to net income as a measure of financial performance or any other performance measure derived in accordance with GAAP, and they should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

We encourage evaluation of these adjustments and believe they are appropriate for supplemental analysis.

In evaluating adjusted EBITDA and adjusted EBITDA margin, be mindful that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation.

There can be no assurance that we will not modify the presentation of adjusted EBITDA and adjusted EBITDA margin in the future, and any such modification may be material.

Our presentation of adjusted EBITDA and adjusted EBITDA margin should not be construed to imply that our future results will be unaffected by any such adjustments.

In addition, other companies, including companies in our industry, may not calculate adjusted EBITDA and adjusted EBITDA margin at all or may calculate Adjusted EBITDA and Adjusted EBITDA margin differently and, accordingly, our calculations of EBITDA and adjusted EBITDA are not necessarily comparable to similar measures of other companies, which could reduce the usefulness of adjusted EBITDA and adjusted EBITDA margin as tools for comparison.

The following table provides a reconciliation of net income to adjusted EBITDA for the periods presented and the calculation of adjusted EBITDA margin:

(1) For the three and six months ended March 31, 2026, the impact of retirement plan events relates to non-cash charges of $1,609 and $3,218 included in Other, net associated with the establishment of a retiree medical plan.

The Company will recognize a non-cash charge related to such plan of $5,362 ratably over the first 10 months of fiscal 2026.

(2) The tax impact for the above reconciling adjustments from GAAP net income to non-GAAP adjusted income from continuing operations, and the related adjusted EPS from continuing operations, 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.
