MOUNT AIRY, N.C., July 16, 2026 – Insteel Industries Inc. (NYSE: IIIN) (“Insteel” or the “Company”), the largest manufacturer of steel wire reinforcing products for concrete construction applications in the United States, today announced financial results for its third quarter of fiscal 2026 ended June 27, 2026.

Third Quarter 2026 Highlights

Third Quarter 2026 Results

• Net earnings of $9.0 million, or $0.46 per share
• Net sales of $197.7 million
• Gross profit of $20.1 million, or 10.2% of net sales
• Increased share repurchase activity, acquiring 75,000 shares for $1.9 million during the quarter
• Net cash balance of $22.9 million and no debt outstanding as of June 27, 2026
• Favorable outlook for the remainder of fiscal 2026 Net earnings for the third quarter of fiscal 2026 decreased to $9.0 million, or $0.46 per share, from $15.2 million, or $0.78 per share, for the same period a year ago. Prior-year results included $0.9 million in restructuring and acquisition-related costs, which reduced net earnings per share by $0.03. Insteel's third quarter results benefited from higher average selling prices and improved shipment activity compared with the prior-year period. However, those benefits were more than offset by higher costs.

Net sales increased 9.9% to $197.7 million from $179.9 million in the prior-year quarter, driven by an 8.0% increase in average selling prices and a 1.7% rise in shipments. Average selling prices benefited from pricing actions implemented across all product lines to recover higher raw material, freight and other operating costs, while shipments increased from the prior-year quarter as demand conditions across our key construction end markets remained generally favorable. Sequentially, average selling prices increased 2.3%, while shipments rose 11.9% from the second quarter.

Gross profit declined to $20.1 million from $30.8 million in the prior year quarter, and gross margin narrowed to 10.2% from 17.1%, primarily due to inflationary pressures across practically all areas of our cost structure, partially offset by increased shipments.

Operating activities generated $13.7 million of cash during the quarter compared with $28.2 million in the prior year quarter due to a combination of a reduction in net earnings and the relative change in net working capital. Net working capital provided $0.5 million in the current year quarter, compared to $9.4 million in the prior year quarter.

Earnings for the prior year period included $2.5 million of restructuring charges and acquisition-related costs, which collectively reduced net earnings per share by $0.10.

Net sales increased to $530.2 million from $470.3 million for the prior year period, driven by a 13.1% increase in average selling prices, while shipment volumes were relatively unchanged. Gross profit decreased to $54.7 million from $64.8 million in the same period a year ago, and gross margin narrowed to 10.3% from 13.8%, due to higher freight and operating expenses.

Operating activities provided $18.0 million of cash compared with $44.2 million in the prior year period, primarily due to a combination of a reduction in net earnings and the relative changes in net working capital. Net working capital used $17.5 million of cash in the current year period, largely to fund increases in inventories, compared with $0.2 million in the prior year period.

Capital Allocation and Liquidity

Capital expenditures for the first nine months of fiscal 2026 increased to $9.1 million from $6.5 million in the comparable prior year period. Capital expenditures for fiscal 2026 are now expected to total approximately $15.0 million, down from our previous expectation of approximately $20.0 million. Planned spending continues to support cost and productivity improvement initiatives, investments in the growth of our engineered structural mesh (“ESM”) business, and routine maintenance requirements. The revised outlook reflects the timing of certain projects rather than any change in our planned investment activities, with a portion of the related expenditures now expected to be incurred in fiscal 2027.

During the third quarter of fiscal 2026, the Company repurchased 75,000 shares of its common stock under its existing share repurchase authorization. During the first nine months of fiscal 2026, Insteel has returned $23.8 million to shareholders through dividends and share repurchases while maintaining a strong balance sheet and ample liquidity. The Company ended the quarter debt-free with $22.9 million of cash and no borrowings outstanding under its $100.0 million revolving credit facility.

Outlook

“The business environment remained supportive during the quarter, as shipment levels increased from the prior-year period,” commented H.O. Woltz III, Insteel’s President and CEO. “Customer sentiment remains positive and the level of activity in publicly funded infrastructure markets continues to be healthy. Private non-residential construction continues to be dominated by data center projects, some of which have experienced schedule delays. We believe these delays are timing-related and do not imply weakening demand. Profitability during the quarter was impacted by higher costs, as increases in wire rod prices, freight expense, and practically all other operating costs outpaced changes in selling prices. We believe these headwinds are temporary and expect to recover these higher costs through our pricing over time.”

Mr. Woltz added, “Looking ahead, the fundamental drivers of demand across our markets remain intact, supported by the Company’s recent investments, and resilience in publicly funded construction and infrastructure-related projects. While we continue to monitor developments related to raw material pricing, transportation costs and trade policy, we are focused on operating efficiently, maintaining strong customer relationships and executing our growth initiatives. We like the Company’s positioning as we move through the remainder of fiscal 2026.”
