Gibraltar Reports Second Quarter 2026 Results

Continuing Operations Net Sales +65%; with Organic Growth +5% Driven By Residential

Continuing Operations EPS: GAAP $0.92, Adjusted $1.11

OmniMax integration on track; Reiterating full year 2026 guidance

Buffalo, New York, August 5, 2026 – Gibraltar Industries, Inc. (Nasdaq: ROCK), a leading manufacturer and provider of products and services for the residential, agtech, and infrastructure markets, today reported its financial results for the three-month and six-month period ended June 30, 2026.

As a reminder, Gibraltar reclassified its Renewables business as discontinued operations on June 30, 2025. Subsequently, the electrical balance-of-systems (eBOS) and racking and foundations businesses were sold on February 20, and July 15, 2026, respectively, completing Gibraltar’s divestiture of Renewables.

“We delivered solid second quarter results with our Residential business driving good organic growth and participation gains in a flat-to-down market. Our building products business grew 12.7% organically - if you assume we owned OmniMax in Q2 2025, the combined business actually grew 15.5%, showing the strength of this combination in the marketplace. In line with our long-term strategic plan, our Residential business overall continues to become a larger part of our portfolio and represented 83% of total revenue in the quarter, with segment EBITDA margin improving sequentially 340 basis points to 19.0%. OmniMax integration continues to accelerate as our leadership team and integration management office drive our top 11 critical workstreams and synergy capture. We are also excited to announce we were recently awarded an additional 630 locations now making us the supplier of trims and flashings to more than 1,700 locations across the country for one of our customers – validating our ability to support our customers locally on a national basis with a value proposition that makes sense for them. We believe the addition of OmniMax to our product portfolio was instrumental in receiving this award,” stated Chairman and CEO Bill Bosway.

“Including a full quarter of OmniMax, total Gibraltar net sales increased 64.6% on organic growth of 5%, adjusted EBITDA increased 59.7%, and we delivered adjusted EPS of $1.11. As expected, we generated cash in our continuing operations during the quarter.”

Balance Sheet and Cash Flow

Gibraltar’s policy with respect to cash allocation will be to keep a minimum amount of cash on hand, use the revolver as needed to fund seasonal working capital and pay down debt with excess cash flow.

During the quarter, Gibraltar generated $44.5 million from continuing operations; discontinued operations used $40.8 million in cash. Net debt on the balance sheet was $1.2 billion and revolving credit facility availability was $470 million at quarter-end.

Reiterating 2026 Outlook Range for Continuing Operations

Mr. Bosway added, “Despite the impact of the current macroeconomic and geopolitical environment and a slow Residential end market, we reiterate our full year 2026 outlook. We will continue to execute our 11 integration workstreams, implement synergy initiatives, and focus on participation gains with customers in our Residential business as we drive towards Residential representing an even larger part of the portfolio. The additional business we were recently awarded in our Residential segment demonstrates the power of a combined Gibraltar and OmniMax in the marketplace. We also expect Agtech and Infrastructure to deliver their respective plans for the second half of the year.”

Forward-Looking Statements

Certain information set forth in this news release, other than historical statements, contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 that are based, in whole or in part, on current expectations, estimates, forecasts, and projections about the Company’s business, and management’s beliefs about future operations, results, and financial position. These statements are not guarantees of future performance and are subject to a number of risk factors, uncertainties, and assumptions. Actual events, performance, or results could differ materially from the anticipated events, performance, or results expressed or implied by such forward-looking statements. Factors that could cause actual results to differ materially from current expectations include, among other things, the ability of Gibraltar to successfully integrate OmniMax and/or to achieve expected cost and operational synergies from the OmniMax transaction; tariffs and retaliatory tariffs imposed by the United States or other countries on imported goods, including raw materials used in the manufacturing of the

Company’s products; changes to economic conditions and customer demand for the Company’s products; the availability and pricing of principal raw materials and component parts, supply chain challenges causing project delays and field operations inefficiencies and disruptions, the loss of any key customers, adverse effects of inflation, the ability to continue to improve operating margins, the ability to generate order flow and sales and increase backlog; the ability to translate backlog into net sales, other general economic conditions and conditions in the particular markets in which we operate, changes in spending due to laws and government incentives, such as the Infrastructure Investment and Jobs Act, changes in customer demand and capital spending, competitive factors and pricing pressures, the ability to develop and launch new products in a cost-effective manner, the ability to realize synergies from newly acquired businesses, disruptions to IT systems, the impact of trade and regulation, rebates, credits and incentives and variations in government spending and ability to derive expected benefits from restructuring, productivity initiatives, liquidity enhancing actions, and other cost reduction actions. Before making any investment decisions regarding the company, we strongly advise you to read the section entitled “Risk Factors” in the most recent annual report on Form 10-K which can be accessed under the “SEC Filings” link of the “Investor Info” page of the website at www.Gibraltar1.com. The Company undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by applicable law or regulation.

Adjusted Financial Measures

To supplement Gibraltar’s consolidated financial statements presented on a GAAP basis, Gibraltar also presented certain adjusted financial measures in this news release and its quarterly conference call, including adjusted net sales, adjusted operating income and margin, adjusted net income, adjusted earnings per share (EPS), free cash flow and adjusted earnings before interest, taxes, depreciation and amortization (Adjusted EBITDA) and Adjusted EBITDA margin, each a non-GAAP financial measure. Unless otherwise indicated, the consolidated financial statements, disclosures and related information disclosed herein relate to the Company's continuing operations, which exclude its Renewables business which was classified as a discontinued operation as of June 30, 2025. The Company has recast prior period amounts to reflect discontinued operations. Adjusted net income, operating income and margin exclude special charges consisting of restructuring costs (primarily comprised of exit activities costs and impairment of assets associated with 80/20 simplification, lean initiatives and / or discontinued products), acquisition related costs (legal and consulting fees, and integration costs for recent business acquisitions), and portfolio management. These special charges are excluded since they may not be considered directly related to the Company’s ongoing business operations. The aforementioned exclusions along with other adjustments to other income below operating profit are excluded from adjusted EPS. Adjusted EBITDA and Adjusted EBITDA margin further excludes interest, taxes, depreciation, amortization and stock compensation expense. In evaluating its business, the Company considers and uses these non-GAAP financial measures as supplemental measures of its operating performance. Free cash flow is operating cash flow less capital expenditures and the related margin is free cash flow divided by net sales. The Company believes that the presentation of adjusted measures and free cash flow provides meaningful supplemental data to investors, as well as management, that are indicative of the Company’s core operating results and facilitates comparison of operating results across reporting periods as well as comparison with other companies. Adjusted EBITDA and free cash flow are also useful measures of the Company’s ability to service debt and adjusted EBITDA is one of the measures used for determining the Company’s debt covenant compliance.

Adjustments to the most directly comparable financial measures presented on a GAAP basis are quantified in the reconciliation of adjusted financial measures provided in the supplemental financial schedules that accompany this news release. These adjusted measures should not be viewed as a substitute for the Company’s GAAP results and may be different than adjusted measures used by other

companies and the Company’s presentation of non-GAAP financial measures should not be construed as an inference that the Company’s future results will be unaffected by unusual or non-recurring items.

Reconciliations of non-GAAP measures related to full-year 2026 guidance have not been provided due to the unreasonable efforts it would take to provide such reconciliations due to the high variability, complexity and uncertainty with respect to forecasting and quantifying certain amounts that are necessary for such reconciliations.
