NEWS RELEASE

INSTEEL INDUSTRIES REPORTS FOURTH QUARTER AND FISCAL 2024 RESULTS

MOUNT AIRY, N.C., October 17, 2024 –– Insteel Industries Inc. (NYSE: IIIN) (“Insteel” or the “Company”), the nation’s largest manufacturer of steel wire reinforcing products for concrete construction applications, today announced financial results for its fourth quarter and fiscal year ended September 28, 2024.

Fourth Quarter 2024 Highlights

Fourth Quarter 2024 Results

Net earnings for the fourth quarter of fiscal 2024 were $4.7 million, or $0.24 per share, compared to $5.6 million, or $0.29 per share, in the same period a year ago. Insteel’s fourth quarter results were unfavorably impacted by narrower spreads between selling prices and raw material costs relative to the prior year quarter, along with lower shipments.

Net sales decreased 14.7% to $134.3 million, down from $157.5 million in the prior year quarter, reflecting a 12.9% decrease in average selling prices and a 2.1% decline in shipments. Average selling prices were negatively affected by persistent competitive pricing pressures in our welded wire reinforcing markets and the impact of low-priced PC strand imports. Shipments for the current year quarter were adversely impacted by weaker market conditions as compared to recent years and adverse weather conditions in certain of our markets during the period. Sequentially, average selling prices decreased 2.8% from the third quarter, while shipments declined 5.2%. Gross margin increased 20 basis points to 9.1% from 8.9% in the prior year quarter, mostly due to lower unit manufacturing costs on higher production volume.

Operating activities generated $16.2 million of cash during the fourth quarter compared to $38.6 million in the prior year quarter due to a reduction in the relative changes in net working capital. Working capital provided $5.3 million of cash in the current year, driven by a reduction in receivables and an increase in accounts payable and accrued expenses, compared to $28.6 million the prior year.

Fiscal 2024 Results

Net earnings for fiscal 2024 decreased to $19.3 million, or $0.99 per share, from $32.4 million, or $1.66 per share, in the prior year. Earnings for the prior year benefited from a $3.3 million, or $0.13 per share, gain on the sale of property, plant, and equipment.

Net sales decreased 18.5% to $529.2 million from $649.2 million in the prior year, driven entirely by a decrease in average selling prices as shipments remained flat. Gross profit decreased to $49.6 million from $65.4 million in the same period a year ago, and gross margin narrowed to 9.4% from 10.1% due to lower spreads.

Operating activities generated $58.2 million of cash compared to $142.2 million in the prior year due to a reduction in net earnings and the relative change in working capital. Working capital provided $18.9 million of cash in the current year, driven by a reduction in inventories and receivables, compared to $95.6 million in the prior year.

Capital Allocation and Liquidity

Capital expenditures for fiscal 2024 decreased to $19.1 million from $30.7 million in the prior year and are expected to total up to approximately $22.0 million in fiscal 2025, primarily focused on cost and productivity improvement initiatives as well as recurring maintenance requirements.

Insteel ended the year with $111.5 million of cash and no borrowings outstanding on its $100.0 million revolving credit facility.

Outlook

“As we move forward into fiscal year 2025, we anticipate a gradual improvement in business conditions across our markets,” commented H.O. Woltz III, Insteel’s President and CEO. “Although recent leading indicators for nonresidential construction spending have been mixed, we expect that declining inflation and the downward trajectory in interest rates will help stimulate demand in the months ahead. Additionally, we remain optimistic about the impact of spending from the Infrastructure Investment and Jobs Act, which is expected to boost infrastructure-related project activity and lay a stronger foundation for future growth.”

Mr. Woltz further commented, “We also acknowledge the challenges ahead as import related headwinds are expected to persist in our PC strand markets, putting further pressure on selling prices, volumes and spreads in our first quarter. We are continuing our efforts to eliminate the section 232 tariff distortion in the PC strand market, and we will carefully consider filing antidumping and countervailing duty actions that are warranted.”

Conference Call

Insteel will hold a conference call at 10:00 a.m. ET today to discuss its fourth quarter and 2024 fiscal year end financial results. A live webcast of this call can be accessed on Insteel’s website at https://investor.insteel.com and will be archived for replay until the next quarterly conference call.
