NEW YORK, NEW YORK, May 8, 2025 – Griffon Corporation (“Griffon” or the “Company”) (NYSE:GFF) today reported results for the fiscal 2025 second quarter ended March 31, 2025.

Revenue for the second quarter totaled $611.7 million, a 9% decrease compared to $672.9 million in the prior year quarter.

Net income totaled $56.8 million, or $1.21 per share, compared to $64.1 million, or $1.28 per share, in the prior year quarter. Excluding all items that affect comparability from both periods, adjusted net income was $57.6 million, or $1.23 per share, in the current year quarter compared to $67.5 million, or $1.35 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 second quarter was $118.5 million, a 12% decrease from the prior year quarter of $134.2 million. Adjusted EBITDA, excluding unallocated amounts (primarily corporate overhead) of $14.6 million in the current quarter and $14.8 million in the prior year quarter, totaled $133.2 million, decreasing 11% from the prior year of $149.0 million. For a reconciliation of adjusted EBITDA, a non-GAAP measure, to income before taxes, and the definition of adjusted EBITDA, see the attached table.

“I am pleased to report that the performance of both of our segments for the first half was in-line with our expectations,” said Ronald J. Kramer, Chairman and CEO of Griffon. “Home and Building Products (“HBP”) maintained a strong 30% EBITDA margin, driven by steady residential performance and favorable mix. Consumer and Professional Products (“CPP”) continued to deliver improving EBITDA margin year-over-year, driven by the transition of our U.S. operations to an asset-light business model and solid performance from our team in Australia.”

“Given our year-to-date performance, we are maintaining our financial guidance for the year, despite the uncertain economic operating conditions,” continued Mr. Kramer. “We expect HBP, which is largely unaffected by tariffs, to generate approximately 85% of our segment EBITDA for the year. We anticipate CPP will be able to mitigate the impact of the current tariff policy and other headwinds through supplier negotiations, cost management, leveraging existing inventory and when necessary, by taking price actions, as we continue our process of leveraging our global supply chain.”

HBP's second quarter revenue of $368.2 million decreased 6% from the prior year quarter due to decreased volume of 7% primarily reflecting residential sales activity returning to normal seasonality, partially offset by favorable product mix of 1%.

Adjusted EBITDA of $109.4 million decreased 15% from $128.9 million in the prior year quarter. The variance to the prior year resulted from decreased revenue noted above and the related volume impact on overhead absorption, and increased labor and distribution costs, partially offset by reduced material costs.

CPP's second quarter revenue of $243.5 million decreased 13% compared to the prior year quarter, primarily driven by decreased volume of 13% due to reduced consumer demand in North America and the United Kingdom ("UK"), partially offset by increased organic volume in Australia. The Pope acquisition contributed 2%. Foreign currency had a 2% unfavorable impact on the current quarter revenue.

Adjusted EBITDA of $23.7 million increased 18% from $20.1 million in the prior year quarter, primarily due to the benefits from the global sourcing expansion initiative and increased volume and improved margin in Australia, partially offset by the unfavorable impact of the reduced North American and UK volume. Foreign currency had a 1% unfavorable impact on the current quarter adjusted EBITDA.

The Company reported pretax income from operations for the quarters ended March 31, 2025 and 2024, and recognized effective tax rates of 27.8% and 27.6%, respectively. Excluding all items that affect comparability, the effective tax rates for the quarters ended March 31, 2025 and 2024 were 27.7% and 27.9%, respectively.

As of March 31, 2025, the Company had cash and equivalents of $127.8 million and total debt outstanding of $1.54 billion, resulting in net debt of $1.41 billion. Leverage, as calculated in accordance with our credit agreement (see the attached table), was 2.6x net debt to EBITDA compared to 2.8x at March 31, 2024 and 2.6x at September 30, 2024. At March 31, 2025, borrowing availability under the revolving credit facility was $364.5 million, subject to certain loan covenants. Free cash flow of $145.8 million for the six month period ended March 31, 2025 reflects the Company's strong operating results through the first half. Capital expenditures, net, were $13.4 million for the quarter ended March 31, 2025. For a reconciliation of free cash flow, a non-GAAP measure, to net cash provided by operating activities, and the definition of free cash flow, see the attached table.

Share repurchases during the quarter ended March 31, 2025 totaled 0.4 million shares for a total of $30.5 million, or an average of $72.64 per share. Since April 2023 and through March 31, 2025, the Company purchased 9.9 million shares of common stock or 17.4% of the outstanding shares, for a total of $498.1 million or an average of $50.09 per share. As of March 31, 2025, $359.8 million remained under the Board authorized share repurchase program.

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:

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 gross profit and selling, general and administrative expenses for items that affect comparability for the three and six months ended March 31, 2025, and 2024:

Griffon evaluates performance based on adjusted net income and the related adjusted earnings per share, which excludes restructuring charges, 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 and six months ended March 31, 2024, restructuring charges relate to the CPP global sourcing expansion, of which $1.3 million and $13.0 million, respectively, are included in Cost of goods and services and $1.1 million and $1.8 million, respectively, are included in SG&A in the Company's Condensed Consolidated Statements 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 statutory and annual effective tax rate on items impacting the quarter.
