NEW YORK, NEW YORK, February 5, 2026 – Griffon Corporation (“Griffon” or the “Company”) (NYSE:GFF) today reported results for the fiscal 2026 first quarter ended December 31, 2025.

Revenue for the first quarter totaled $649.1 million, a 3% increase compared to $632.4 million in the prior year quarter.

Net income totaled $64.4 million, or $1.41 per share, compared to $70.9 million, or $1.49 per share, in the prior year quarter. Excluding all items that affect comparability from both periods, adjusted net income (a non-GAAP measure) was $66.3 million, or $1.45 per share, in the current year quarter compared to $65.9 million, or $1.39 per share, in the prior year quarter. For a reconciliation of net income to adjusted net income (a non-GAAP measure), and earnings per share to adjusted earnings per share (a non-GAAP measure), see the attached table.

Adjusted EBITDA for the first quarter was $129.6 million, a 1% decrease from the prior year quarter of $131.2 million. Adjusted EBITDA, excluding unallocated amounts (primarily corporate overhead) of $15.0 million in the current quarter and $14.0 million in the prior year quarter, totaled $144.6 million in the current quarter compared to the prior year of $145.2 million. For a reconciliation and definition of adjusted EBITDA (a non-GAAP measure), to income before taxes, see the attached table.

“We are pleased with our first quarter performance, highlighted by free cash flow of $99 million, continued solid operating performance at Home and Building Products, and improved profitability at Consumer and Professional Products,” said Ronald J. Kramer, Chairman and Chief Executive Officer. “We are on track to meet our updated financial targets for the year.”

HBP's first quarter revenue of $408.0 million increased 3% from $395.4 million in the prior year quarter primarily due to favorable pricing and mix of 7% for both residential and commercial, partially offset by reduced volume of 4% driven by residential.

Adjusted EBITDA of $122.8 million decreased 3% from $127.0 million in the prior year quarter resulting from increased material costs, labor costs and operating expenses and the impact of reduced volume on absorption, partially offset by the increased revenue noted above.

CPP's first quarter revenue of $241.1 million increased 2% compared to the prior year quarter, primarily driven by price and mix with increased volume in Australia and Canada, offset by decreased volume in the United States.

Adjusted EBITDA of $21.7 million increased 19% compared to the prior year quarter, primarily due to the net increase in revenue noted above.

The Company reported pre-tax income for the quarters ended December 31, 2025 and December 31, 2024, and recognized effective tax rates of 28.4% and 27.3%, respectively. Excluding all items that affect comparability, the effective tax rates for the quarters ended December 31, 2025 and 2024 were 28.0% and 27.7%, respectively.

As of December 31, 2025, the Company had cash and equivalents of $95.3 million and total debt outstanding of $1.35 billion, resulting in net debt of $1.26 billion. During the quarter, debt was reduced by approximately $60.0 million. Leverage, as calculated in accordance with our credit agreement (see the attached table), was 2.3x net debt to EBITDA as of December 31, 2025 compared to 2.4x as of both December 31, 2024 and September 30, 2025. Free cash flow was $99.3 million for the three month period ended December 31, 2025. Capital expenditures, net, were $7.7 million for the quarter ended December 31, 2025. At December 31, 2025, borrowing availability under the revolving credit facility was $485.7 million, subject to certain loan covenants. For a reconciliation and definition of free cash flow (a non-GAAP measure), to net cash provided by operating activities, see the attached table.

Share repurchases during the quarter ended December 31, 2025 totaled 0.2 million shares of common stock, for a total of $18.1 million, or an average of $73.21 per share. As of December 31, 2025, $280.0 million remained under the Board authorized share repurchase program. Since April 2023 and through December 31, 2025, the Company purchased 11.1 million shares of common stock or 19.3% of the outstanding shares, for a total of $578.0 million or an average of $52.27 per share.

Earlier today, Griffon announced it has entered into a definitive agreement with ONCAP, the mid-market private equity platform of Onex Corporation (TSX:ONEX), to form a joint venture which will include CPP’s AMES U.S. and Canada businesses. In addition, Griffon announced the exploration of strategic alternatives for CPP’s AMES Australia and UK businesses, and the combination of Hunter Fan with the HBP segment.

Starting with Griffon’s fiscal second quarter, AMES U.S., Canada, Australia, and UK will be reported as discontinued operations.

As a result of the strategic actions noted above, Griffon now expects fiscal 2026 revenue from continuing operations to be $1.8 billion and Adjusted EBITDA to be $520 million, excluding unallocated costs of $62 million. Free cash flow from continuing operations, including capital expenditures of $50 million, is expected to exceed net income, with depreciation of $27 million and amortization of $15 million. Fiscal year 2026 interest expense is expected to be $93 million, and Griffon’s normalized tax rate is expected to be 28%.

This fiscal year 2026 outlook is consistent with the contributions from both the legacy HBP segment and Hunter Fan included within Griffon’s guidance provided in November 2025.

EVP & Chief Financial Officer Managing Director 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.

The following tables provide operating highlights and a reconciliation of segment adjusted EBITDA and adjusted EBITDA to income before taxes:

*Primarily Corporate Overhead

Griffon believes free cash flow ("FCF", a non-GAAP measure) is a useful measure for investors because it demonstrates the Company's ability to generate cash from operations for purposes such as repaying debt, funding acquisitions and paying dividends. FCF is defined as net cash provided by operating activities less capital expenditures, net of proceeds.

The following table provides a reconciliation of net cash provided by operating activities to FCF:

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. The following table provides a calculation of our net debt to EBITDA leverage ratio as calculated per our credit agreement:

The following tables provide a reconciliation of selling, general and administrative expenses for items that affect comparability for the three months ended December 31, 2025 and 2024:

Griffon evaluates performance based on adjusted net income and the related adjusted earnings per share, which excludes the impact of retirement plan events, gain/loss from debt extinguishment, acquisition related expenses, discrete and certain other tax items, as well other items that may affect comparability, as applicable, non-GAAP measures. Griffon believes this information is useful to investors. The following table provides a reconciliation of net income to adjusted net income and earnings per common share to adjusted earnings per common 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, 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 statutory and annual effective tax rate on items impacting the quarter.
