"We delivered fourth‑quarter results ahead of our expectations and closed out the fiscal year strongly. The teams executed well as they continued to serve our customers in a dynamic operating environment,” said Donald Nolan, Executive Chair and CEO. “Throughout the fiscal year, we continued to focus on our priorities while actively managing our cost structure and returning cash to shareholders through dividends and share buybacks. This, along with generating strong cash flow, supports a resilient and flexible balance sheet for future growth opportunities."

“We intend to maintain prudent and disciplined cost management while being thoughtful and selective in pursuing growth investments, prioritizing opportunities with clear strategic alignment and financial returns that support long‑term value creation."

Fourth-Quarter Consolidated Results (Fourth Quarter Fiscal 2026 compared to Fourth Quarter Fiscal 2025)

•Net sales increased 1.6% to $351.4 million, driven by favorable price and mix, partially offset by lower volume.

•Gross margin rose 80 basis points to 22.4%, primarily due to a non-recurring $9.4 million arbitration decision expensed in the prior year, productivity improvements including savings from Project Fortify 2, and lower risk-related insurance expenses, partially offset by higher aluminum costs, impacts from lower volume, and higher health insurance costs.

•Selling, general and administrative (SG&A) expenses as a percentage of net sales decreased 470 basis points to 15.1%, primarily due to a non-recurring impairment charge in the Metals segment in the prior year, lower incentive compensation, acquisition-related expenses incurred in the prior year, and benefits from cost savings of Fortify Phase 2, partially offset by restructuring related expenses.

•Operating income increased to $25.8 million from $6.1 million, and operating margin increased 550 basis points to 7.3%.

•Adjusted EBITDA increased to $42.4 million, compared to $41.1 million, and adjusted EBITDA margin increased to 12.1%, compared to 11.9%.

Management uses non-GAAP measures to evaluate the Company’s historical and prospective financial performance, measure operational profitability on a consistent basis, as a factor in determining executive compensation, and to provide enhanced transparency to the investment community. Non-GAAP measures should be viewed in addition to, and not as a substitute for, the reported financial results of the Company prepared in accordance with GAAP. Other companies may calculate these measures differently, limiting the usefulness of the measures for comparison with other companies. This release and other financial communications may contain the following non-GAAP measures:

•Adjusted operating income, adjusted operating margin, adjusted net earnings, and adjusted diluted EPS are used by the Company to provide meaningful supplemental information about its operating performance by excluding amounts that the Company does not consider to be part of core operating results, to enhance comparability of results from period to period.

•Adjusted EBITDA represents adjusted net earnings before interest, taxes, depreciation, and amortization. The Company believes adjusted EBITDA and adjusted EBITDA margin metrics provide useful information to investors and analysts about the Company’s core operating performance.

•Consolidated Leverage Ratio is calculated as Consolidated Funded Indebtedness minus Unrestricted Cash at the end of the current period, divided by Consolidated EBITDA . All capitalized and undefined terms used in this bullet are defined in the Company’s credit agreement dated July 19, 2024, and defined as an exhibit to our form 10-K for the year ended March 1, 2025. The Company is unable to present a quantitative reconciliation of forward-looking expected Consolidated Leverage Ratio to its most directly comparable forward-looking GAAP financial measure because such information is not available, and management cannot reliably predict all the necessary components of such GAAP financial measure without unreasonable effort or expense. In addition, the Company believes such reconciliation would imply a degree of precision that would be confusing or misleading to investors.

•Backlog is defined as the dollar amount of signed contracts or firm orders, generally as a result of a competitive bidding process, which is expected to be recognized as revenue. Backlog is an operating measure used by management to assess future potential sales revenue. It is most meaningful for the Architectural Services segment, due to the longer-term nature of their projects. Backlog is not a term defined under U.S. GAAP and is not a measure of contract profitability. Backlog should not be used as

the sole indicator of future revenue because the Company has a substantial number of projects with short lead times that book-and-bill within the same reporting period that are not included in backlog.

New factors emerge from time to time, and it is not possible for management to predict all such factors, nor can it assess the impact of each factor on the business or the extent to which any factor, or a combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.
