George Wilson, Chairman, President and Chief Executive Officer, stated, “Volumes continued to track normal seasonality patterns during the third quarter of 2026, and we made meaningful progress addressing the price versus cost imbalance that impacted our margins in the second quarter of 2026. Inflationary pressures related to macroeconomic concerns and the ongoing conflict in the Middle East are still having an impact, but the initial rate and magnitude of these pressures have somewhat subsided.

“We stayed focused on managing our working capital during the third quarter of 2026, which when coupled with the seasonal uptick in volumes, enabled us to repay $42.25 million of debt and buy back some of our shares. We will continue to prioritize repaying debt and opportunistically repurchasing our shares as we generate cash in the fourth quarter of 2026. In addition, we will continue to identify operational efficiencies and commercial synergies that we believe will benefit us when consumer confidence and demand improve.”

Third Quarter 2026 Results Summary   

Quanex reported net sales of $501.8 million during the three months ended July 31, 2026, which represents an increase of 1.3% compared to $495.3 million for the same period in 2025, mainly due to favorable impacts from pricing, partially offset by the impact of IEEPA tariff reimbursements to customers. The Hardware Solutions segments reported a 2.7% decline in net sales for the third quarter of 2026, driven by lower volumes and the impact of IEEPA tariff reimbursements to customers, which were somewhat offset by favorable impacts from pricing. The Extruded Solutions segments reported net sales growth of 2.8% for the third quarter of 2026, as lower volumes were more than offset by favorable impacts from pricing. Quanex reported an increase of 8.5% in net sales for the third 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 increase in reported earnings for the third quarter of 2026 compared to the third quarter of 2025 was mainly due to improved pricing, lower depreciation and amortization expense and lower interest expense. Results for the third quarter of 2025 were also impacted by a $302.3 million non-cash goodwill impairment.

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.
