“We are pleased with the second-quarter results which exceeded our expectations, driven by strong execution across the business. The benefits of disciplined pricing, productivity initiatives, and ongoing operational improvements helped offset a mixed demand environment," said Don Nolan, Executive Chair and Chief Executive Officer.

"The momentum we established in the first half of the year, combined with our confidence in the business, supports our decision to raise full-year guidance. We also advanced our strategic priorities through the

acquisitions of Kalwall and Groglass. Early performance at Kalwall has been encouraging, and we believe the addition of Groglass will further strengthen our portfolio through differentiated capabilities and increased exposure to attractive end markets that support long-term value creation."

Second Quarter Consolidated Results (Second Quarter Fiscal 2027 compared to Second Quarter Fiscal 2026)

•Net sales increased 9.2% to $391.1 million, driven by a $16.4 million contribution from the Kalwall acquisition, price, and favorable mix, partially offset by lower volume.

•Gross margin rose 150 basis points to 24.6%, primarily due to price, productivity improvements, including the net benefit from Project Fortify 2, and the accretive impact of the Kalwall acquisition, partially offset by higher material and manufacturing costs and impacts from lower volume.

•Selling, general and administrative (SG&A) expenses as a percentage of net sales increased 40 basis points to 16.0%, primarily due to higher incentive compensation expense, partially offset by cost savings from Fortify Phase 2.

•Operating income increased to $33.5 million from $26.9 million, and operating margin increased 110 basis points to 8.6%.

•Adjusted EBITDA increased to $49.5 million, compared to $44.4 million, and adjusted EBITDA margin increased to 12.7%, compared to 12.4%.

•Other income decreased to $0.5 million from $5.1 million, primarily due to a nonrecurring New Markets Tax Credit.

•Interest expense decreased to $3.6 million, compared to $4.1 million, primarily due to lower average debt balance.

•Diluted earnings per share (EPS) were $1.07, compared to $1.10, and adjusted diluted EPS increased to $1.17, compared to $0.98.

Second Quarter Segment Results (Second Quarter Fiscal 2027 Compared to Second Quarter Fiscal 2026)

Architectural Metals

Net sales increased 1.8% to $143.5 million, driven by favorable price, partially offset by lower volume. Adjusted EBITDA was $22.1 million, or 15.4% of net sales, compared to $20.8 million, or 14.8% of net sales. The higher adjusted EBITDA margin was primarily driven by price, improved productivity and cost savings from Fortify Phase 2, and favorable mix, partially offset by the net impact from higher aluminum costs and lower volume.

Architectural Services

Net sales increased 7.9% to $108.5 million, primarily due to increased volume. Adjusted EBITDA was $6.2 million, or 5.8% of net sales, compared to $5.0 million, or 5.0% of net sales. The increase in adjusted EBITDA margin was primarily driven by project mix and higher volume. Segment backlog1 at the end of the quarter was $833.0 million compared to $792.3 million at the end of fiscal year 2026.

Architectural Glass

Net sales increased 21.1% to $87.4 million, driven by a $16.4 million contribution from the Kalwall acquisition and favorable mix, partially offset by lower volume and price. Adjusted EBITDA was $13.0 million, or 14.9% of net sales, compared to $11.6 million, or 16.1% of net sales. The decrease in adjusted EBITDA margin was

primarily driven by price, higher manufacturing and freight costs, and lower volume, partially offset by the accretive contribution of the Kalwall acquisition and favorable mix.

Performance Surfaces

Net sales increased 14.2% to $55.3 million due to higher volume and price. Adjusted EBITDA was $12.4 million, or 22.5% of net sales compared to $11.2 million, or 23.2% of net sales. The decrease in adjusted EBITDA margin was primarily driven by the impact of higher material costs, partially offset by price and increased volume.

Corporate and Other

Corporate and other adjusted EBITDA was an expense of $4.2 million, compared to $4.3 million in the prior year. The improvement was primarily due to the benefits from cost savings related to Fortify Phase 2 and lower health insurance costs, partially offset by higher incentive compensation expense.

Financial Condition

Fiscal year-to-date, net cash provided by operating activities was $43.3 million, compared to $37.3 million in the prior year period.

Fiscal year-to-date, the Company returned $27.3 million of cash to shareholders, through $16.1 million of share repurchases and $11.2 million of dividends.

Quarter-end long-term debt increased to $335.5 million, bringing the Consolidated Leverage Ratio2 (as defined in the Company’s credit agreement) to 1.7x at the end of the quarter.

Fiscal 2027 Outlook

Reflecting stronger-than-expected first-half performance, the anticipated contributions from Kalwall and Groglass, and current macroeconomic conditions, the Company is raising its fiscal 2027 outlook. The Company now expects net sales in the range of $1.46 billion to $1.50 billion, compared with its previous range of $1.38 billion to $1.43 billion, and adjusted diluted EPS in the range of $3.00 to $3.40, compared with its previous range of $2.70 to $3.25. The Company’s outlook also assumes interest expense of approximately $15 million, an adjusted effective tax rate of approximately 26%, and capital expenditures between $35 million and $40 million.

The Company will host a conference call today at 8:00 a.m. Central Time to discuss this earnings release. This call will be webcast and is available in the Investor Relations section of the Company’s website, along with presentation slides, at https://www.apog.com/events-and-presentations.

Use of Non-GAAP Financial Measures

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 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. The Company is unable to provide a quantitative reconciliation of its forward-looking adjusted diluted EPS guidance to the most directly comparable GAAP measure without unreasonable effort because it cannot reliably predict the timing and magnitude of certain items, including acquisition-related costs, integration costs, restructuring-related items, and other discrete items that could materially affect GAAP results.

•Adjusted EBITDA represents adjusted net earnings before interest, taxes, depreciation, and amortization. The Company uses adjusted EBITDA and adjusted EBITDA margin to assess segment performance and make decisions about the allocation of operating and capital resources by analyzing recent results, trends, and variances of each segment in relation to forecasts and historical 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 and not otherwise defined herein are defined in the Company’s credit agreement dated July 19, 2024, which is included as an exhibit to the Company’s most recent Annual Report on form 10-K. 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 without unreasonable effort because management cannot reliably predict all the necessary components of that GAAP measure. In addition, the Company believes such reconciliation could 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.

materials used in our products and the impact of trade policies and regulations, including existing and potential future tariffs; (L) the ability to complete announced acquisitions on expected terms and timing; the successful integration and future operating performance of acquired businesses; and the ability to achieve anticipated benefits, including cost synergies, within expected timeframes; (M) our ability to successfully manage and implement our enterprise strategy; (N) our ability to maintain effective internal controls over financial reporting; (O) our judgments regarding accounting for tax positions and resolution of tax disputes; (P) the impacts of cost inflation and interest rates; and (Q) the impact of changes in capital and credit markets on our liquidity and cost of capital.
