HOUSTON, June 04, 2026 (GLOBE NEWSWIRE) -- Quanex Building Products Corporation (NYSE:NX) (“Quanex” or the “Company”) today announced its results for the three months ended April 30, 2026.

George Wilson, Chairman, President and Chief Executive Officer, commented, “Despite the headwinds our industry is facing, demand for the products we manufacture was as expected during the second quarter of 2026. Rapid inflationary pressures related to macroeconomic concerns and the ongoing conflict in the Middle East led to an unfavorable price versus cost dynamic, which pressured our margins. As previously disclosed, we utilize surcharges to respond to rapid increases in costs and we have index pricing mechanisms in place in North America to handle fluctuations in major raw material costs, but when costs increase quickly there is a timing lag and margins are negatively impacted. We are addressing the current price versus cost imbalance to minimize further negative impact and expect to recover some of the shortfall to date during the second half of this year, assuming volumes continue to track the normal seasonality of our business, and the rate of inflationary pressure subsides.

“We expected to be a net borrower during the second quarter due to the seasonality of our business, coupled with the longer cash conversion cycle of the legacy Tyman business, but continued execution on managing working capital, coupled with the seasonal uptick in volumes, enabled us to avoid being a net borrower for the quarter. We intend to prioritize debt repayment and opportunistic share repurchases as we generate cash in the second half. In addition, we will continue to focus on the things we can control, which includes identifying operational efficiencies and commercial synergies that we believe will benefit us when consumer confidence improves and demand rebounds.”

Second Quarter 2026 Results Summary   

Quanex reported net sales of $462.4 million during the three months ended April 30, 2026, which represents an increase of 2.2% compared to $452.5 million for the same period in 2025, mainly due to favorable impacts from pricing, including tariff-related price recoveries, and foreign exchange translation. The Hardware Solutions and Extruded Solutions segments each reported modest increases in net sales for the second quarter of 2026, as lower volumes were offset by favorable impacts from pricing, including tariff-related recoveries and foreign exchange translation. Quanex reported an increase of 6.6% in net sales for the second quarter of 2026 in its Custom Solutions segment, largely due to increased volume and improved pricing. (See Sales Analysis table for additional information)

On a consolidated basis, the decrease in adjusted earnings for the second quarter of 2026 compared to the second quarter of 2025 was mainly due to reduced operating leverage from lower volumes related to ongoing macroeconomic uncertainty combined with weak consumer confidence, tariff-related costs and inflationary pressures. More specifically, due to the ongoing war in the Middle East, the Company realized a significant increase in transportation and raw material costs during the quarter.     

Balance Sheet & Liquidity Update

As of April 30, 2026, the Company had total debt of $715.0 million and Quanex’s leverage ratio of Net Debt to LTM Adjusted EBITDA was 3.1x. As of April 30, 2026, Quanex reported a LTM Net Loss of $257.2 million, mainly due to the non-cash goodwill impairment charge recorded in the third quarter of 2025, and LTM Adjusted EBITDA of $212.8 million (See Non-GAAP Terminology Definitions and Disclaimers section, Net Debt Reconciliation table and Last Twelve Months Adjusted EBITDA Reconciliation table for additional information)

The Company’s liquidity was $328.6 million as of April 30, 2026, consisting of $63.7 million in cash on hand plus availability under its Senior Secured Revolving Credit Facility due 2029, less letters of credit outstanding.

Non-GAAP Terminology Definitions and Disclaimers

Adjusted Net Income (defined as net income further adjusted to exclude amortization of step-up for purchase price adjustments on inventory, asset impairment charges, transaction, advisory fees and reorganization costs, restructuring charges related to severance and disposal of software, amortization expense related to intangible assets, pension settlement refund and other net adjustments related to foreign currency transaction gain/loss and effective tax rates reflecting impacts of adjustments on a with and without basis) and Adjusted EPS are non-GAAP financial measures that Quanex believes provide a consistent basis for comparison between periods and more accurately reflect operational performance, as they are not influenced by certain income or expense items not affecting ongoing operations. EBITDA (defined as net income or loss before interest, taxes, depreciation and amortization and other, net), Adjusted EBITDA and LTM Adjusted EBITDA (defined as EBITDA further adjusted to exclude purchase price accounting inventory step-ups, transaction costs, certain severance charges, gain/loss on the sale of certain fixed assets, restructuring charges and asset impairment charges) are non-GAAP financial measures that the Company uses to measure operational performance and assist with financial decision-making.  Net Debt is defined as total debt (outstanding balance on the revolving credit facility plus financial lease obligations) less cash and cash equivalents. The leverage ratio of Net Debt to LTM Adjusted EBITDA is a financial measure that the Company believes is useful to investors and financial analysts in evaluating Quanex’s leverage. In addition, with certain limited adjustments, this leverage ratio is the basis for a key covenant in the Company’s credit agreement.

Free Cash Flow is a non-GAAP measure calculated using cash provided by operating activities less capital expenditures. Quanex uses the Free Cash Flow metric to measure operational and cash management performance and assist with financial decision-making.   Free Cash Flow is measured before application of certain contractual commitments (including capital lease obligations), and accordingly is not a true measure of the Company’s residual cash flow available for discretionary expenditures. Quanex believes Free Cash Flow is useful to investors in understanding and evaluating the Company’s financial and cash management performance.

Quanex believes that the presented non-GAAP measures provide a consistent basis for comparison between periods and will assist investors in understanding the Company’s financial performance when comparing results to other investment opportunities.  These measures allow management and investors to evaluate operational performance and trends without the impact of certain non-cash charges, acquisition-related costs, and other items that may vary significantly from period to period and may not be reflective of Quanex’s core operating results. The presented non-GAAP measures may not be the same as those used by other companies. The Company does not intend for this information to be considered in isolation or as a substitute for other measures prepared in accordance with U.S. GAAP.
