NEWS RELEASE

INSTEEL INDUSTRIES REPORTS SECOND QUARTER 2026 RESULTS

MOUNT AIRY, N.C., April 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 reported financial results for its second quarter of fiscal 2026, ended March 28, 2026.

Second Quarter 2026 Highlights

Second Quarter 2026 Results

Net earnings for the second quarter of fiscal 2026 decreased to $5.2 million, or $0.27 per share, from $10.2 million, or $0.52 per diluted share, in the same period a year ago. Prior year results included $0.7 million in restructuring charges and acquisition-related costs, which collectively reduced net earnings per share by $0.03. Insteel’s second quarter results were unfavorably impacted by narrower spreads between selling prices and raw material costs, lower shipments and elevated unit manufacturing costs.

Net sales increased 7.5% to $172.7 million from $160.7 million in the prior-year quarter, driven by a 14.2% increase in average selling prices, partially offset by a 5.9% decline in shipments. Higher average selling prices reflect ongoing pricing actions implemented to offset increased raw material and operating costs. The decline in shipments was driven mainly by widespread and prolonged winter weather disruptions across most of our markets, which limited construction activity and constrained operating schedules for both customers and Insteel. Sequentially, shipments grew 6.9% from the first quarter, while average selling prices rose 1.0%. Gross profit decreased to $16.5 million from $24.5 million, and gross margin narrowed to 9.6% from 15.3% in the prior‑year quarter, primarily reflecting reduced spreads, lower shipment volumes and higher operating costs driven in part by weather‑related operational inefficiencies.

Operating activities provided $4.8 million of cash while using $3.3 million in the prior year quarter, primarily due to the relative changes in net working capital and the decrease in net earnings. Net working capital used $1.4 million in the current quarter, driven by an increase in accounts receivable partially offset by a reduction in inventories, compared to $21.9 million in the prior year quarter.

Six Month 2026 Results

Net earnings for the first six months of fiscal 2026 increased to $12.8 million, or $0.65 per diluted share, from $11.3 million, or $0.58 per share, in the same period a year ago. Earnings for the prior year period included $1.7 million in restructuring charges and acquisition-related costs, which collectively reduced net earnings per share by $0.07.

Net sales increased to $332.6 million from $290.4 million for the prior year period, driven by a 16.2% rise in average selling prices partially offset by a 1.5% decrease in shipments. Gross profit increased to $34.6 million from $34.1 million in the same period a year ago, while gross margin narrowed to 10.4% from 11.7% due primarily to higher operating costs.

Operating activities provided $4.4 million of cash compared with $15.7 million in the prior year period, primarily due to the relative changes in net working capital. Net working capital used $18.0 million of cash in the current year period to fund an increase in inventories, compared to $9.6 million in the prior year period.

Capital Allocation and Liquidity

Capital expenditures for the first six months of fiscal 2026 increased to $5.9 million from $4.9 million in the comparable prior year period. Capital outlays for fiscal 2026 are expected to total up to approximately $20.0 million, primarily directed toward cost and productivity improvement initiatives, investments in the growth of our engineered structural mesh (“ESM”) business, and routine maintenance requirements.

Insteel ended the quarter with $15.1 million of cash and no borrowings outstanding on its $100.0 million revolving credit facility.

Outlook

“Winter weather affected most of our facilities and geographies during the quarter, limiting shipments as construction activity slowed and the supply chain experienced operational disruptions,” commented H.O. Woltz III, Insteel’s President and CEO. “Additionally, certain projects that had initially scheduled deliveries in Q2 were delayed until later in our fiscal year, unrelated to weather conditions. I should emphasize that these are delays rather than cancellations. We view these events as temporary and not indicative of underlying demand, which we continue to believe is healthy. If our assumption is correct, shipment levels should strengthen, supported by continued momentum in nonresidential construction markets, the typical seasonal pickup in activity, and the carryover of weather‑delayed projects. We are optimistic about demand in our markets, and believe we are well‑positioned to benefit as activity levels increase.”

Mr. Woltz added, “Beyond the near‑term effects of winter weather, broader market forces continue to shape our operating environment, particularly those tied to raw material availability and pricing, evolving U.S. trade policy, and ongoing geopolitical tension in the Middle East. Domestic hot‑rolled wire rod prices remain far above global levels, practically eliminating the intended impact of the Section 232 derivative product initiative pursued by the Administration in 2025. Even so, we are comfortable with our market position that includes minimal direct import competition but we remain concerned by the disconnect between U.S. pricing for hot-rolled steel relative to the world market level. Inflationary conditions continue to adversely affect our cost profile as we have experienced increased tariff costs, significant increases in energy costs, and recently, sharply escalating freight costs. As we move forward, we will remain focused on disciplined pricing, operational efficiency, and maintaining strong relationships with our customers, which we believe positions us to navigate these market conditions effectively.”
