INSTEEL INDUSTRIES REPORTS THIRD QUARTER 2025 RESULTS

MOUNT AIRY, N.C., July 17, 2025 – 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 2025 ended June 28, 2025.

Third Quarter 2025 Highlights

● Net earnings of $15.2 million, or $0.78 per share

● Net sales of $179.9 million

● Gross profit of $30.8 million, or 17.1% of net sales

● Operating cash flow of $28.2 million

● Net cash balance of $53.7 million and no debt outstanding as of June 28, 2025

● Navigating near-term challenges with cautiously optimistic outlook

Third Quarter 2025 Results

Net earnings for the third quarter of fiscal 2025 increased to $15.2 million, or $0.78 per share, from $6.6 million, or $0.34 per share, for the same period a year ago. The results for the current quarter include $0.9 million in restructuring charges and acquisition-related costs, which collectively reduced net earnings per share by $0.03. Insteel’s third quarter performance was driven by higher shipments of its concrete reinforcement products along with wider spreads between selling prices and raw material costs, partially offset by an increase in selling, general and administrative expense driven by higher incentive plan expense.

Net sales rose 23.4% to $179.9 million from $145.8 million in the prior year quarter, driven by an 11.7% rise in average selling prices and a 10.5% increase in shipments. Higher average selling prices reflect pricing actions taken across all product lines to recover escalating raw material and operating costs. The rise in shipments was driven by the incremental volume generated from acquisitions completed earlier in the year and improved demand in construction markets. Sequentially, average selling prices increased by 8.2% from the second quarter of fiscal 2025, while shipments were up 3.5%. Gross profit improved to $30.8 million from $15.4 million in the prior year quarter, and gross margin expanded to 17.1% from 10.6%, reflecting the improvement in market conditions.

Operating activities generated $28.2 million of cash during the quarter compared with $18.7 million in the prior year quarter due to a combination of higher net earnings and the relative change in net working capital. Net working capital provided $9.4 million in the current year, compared to $7.8 million in the prior year quarter.

Nine Month 2025 Results

Net earnings for the first nine months of fiscal 2025 were $26.5 million, or $1.35 per diluted share, compared with $14.6 million, or $0.75 per share, for the same period a year ago. Insteel’s earnings for the current year period reflect $2.5 million of restructuring charges and acquisition-related costs, which collectively reduced net earnings per share by $0.10.

Net sales increased to $470.3 million from $394.9 million for the prior year period, driven by a 16.5% increase in shipments and a 2.2% rise in average selling prices. Gross profit increased to $64.8 million from $37.4 million in the same period a year ago, and gross margin widened to 13.8% from 9.5% due to improved conditions in reinforcing markets. Operating activities generated $44.2 million of cash compared with $42.0 million in the prior year period due to a combination of higher net earnings and the relative change in net working capital.

Capital Allocation and Liquidity

Capital expenditures for the first nine months of fiscal 2025 decreased to $6.5 million from $17.5 million in the comparable prior year period. Capital outlays for fiscal 2025 are expected to total up to approximately $11.0 million, primarily focused on cost and productivity improvement initiatives as well as recurring maintenance requirements. During fiscal 2025, the Company’s investment program in its facilities was temporarily slowed by integration activities related to recent acquisitions.

Insteel ended the quarter debt-free with $53.7 million of cash and no borrowings outstanding on its $100.0 million revolving credit facility.

Outlook

“As we had previously indicated, we experienced sourcing challenges during our third quarter related to reduced domestic capacity to produce steel wire rod, our primary raw material,” said H.O. Woltz III, President and CEO of Insteel. “Reduced domestic supplies of wire rod disrupted our production schedules, extended lead times, and impacted our ability to fully meet customer demand. As we indicated we would do, we turned to international markets to fill the supply gap, which will ease supply constraints moving forward into the fourth quarter.

“Alongside these availability challenges, we experienced sharply escalating wire rod prices in both domestic and international markets. Contributing to the upward pressure on prices was the unexpected decision by the Administration to double the Section 232 tariff on steel imports, which will affect our cost for substantial quantities of offshore purchases and require disciplined pricing strategies moving forward as we seek to recover higher costs in our markets.”

Mr. Woltz continued, “Despite these challenges, we remain confident in our business outlook. Our recent acquisitions are meaningfully contributing to our performance by enhancing shipment volumes and improving our competitive positioning in certain geographies. We are encouraged that customers generally express optimism about their business prospects, and demand has improved, even as broader macroeconomic indicators for the construction activity suggest a more cautious environment. That said, we are taking proactive steps to manage our costs and remain confident in our long-term competitive positioning.”
