INSTEEL INDUSTRIES REPORTS FIRST QUARTER FINANCIAL RESULTS

MOUNT AIRY, N.C., January 27, 2011 — Insteel Industries, Inc. (NasdaqGS: IIIN) today reported a net loss of $7.6 million ($0.44 per share) for the first quarter of fiscal 2011 compared with a net loss of $1.1 million ($0.07 per share) in the first quarter of fiscal 2010. The net loss for the current year quarter includes $2.8 million of acquisition-related costs ($0.10 per share after-tax) and $4.4 million of restructuring charges ($0.16 per share after-tax) related to the acquisition of certain of the assets of Ivy Steel & Wire, Inc. (“Ivy”). The net loss for the prior year quarter includes $1.9 million of inventory write-downs ($0.07 per share after-tax) to reduce the carrying value of inventory to the lower of cost or market.

Net sales for the first quarter of fiscal 2011 increased 27.0% to $52.3 million from $41.2 million in the first quarter of fiscal 2010 due to the addition of Ivy’s facilities and higher sales at the Company’s existing facilities. Shipments for the first quarter of fiscal 2011 increased 15.9% from the prior year quarter and average selling prices increased 9.5%. On a sequential basis, shipments decreased 7.7% from the fourth quarter of fiscal 2010 due to the usual seasonal downturn while average selling prices increased 0.9%.

Insteel’s financial results for the first quarter of fiscal 2011 were unfavorably impacted by compressed spreads between selling prices and raw material costs, and elevated unit conversion costs. Demand for the Company’s products continued to trend at depressed levels as the seasonal weakness was compounded by the recessionary conditions in the construction sector. Insteel’s overall capacity utilization for the quarter was 35% compared with 49% in the fourth quarter of fiscal 2010 and 33% in the first quarter of fiscal 2010.

Operating activities used $5.1 million of cash for the first quarter of fiscal 2011 compared with $9.8 million in the first quarter of fiscal 2010 as net working capital provided $2.0 million of cash during the current year quarter while using $12.9 million in the prior year quarter. Capital expenditures for the current year quarter were $0.5 million and are expected to total less than $10.0 million for fiscal 2011. Insteel ended the quarter with $2.8 million of cash and cash equivalents, $13.5 million of total debt and no borrowings outstanding on its $75.0 million revolving credit facility.

Ivy Acquisition and Restructuring Activities

On November 19, 2010, Insteel, through its wholly-owned subsidiary, Insteel Wire Products Company, acquired certain of the assets of Ivy for an adjusted purchase price of $50.8 million, after giving effect to the post-closing working capital adjustment and subject to certain additional post-closing adjustments. Under the terms of the purchase agreement, Insteel acquired, among other assets, certain of Ivy’s inventories and its production facilities located in Hazleton, Pennsylvania; Jacksonville, Florida; Kingman, Arizona; and St. Joseph, Missouri, in addition to the production equipment located at its

Houston, Texas facility, for $37.3 million of cash and a $13.5 million secured subordinated note payable over five years.

The Company is proceeding with its previously announced plans to consolidate its Texas and Northeast operations, closing the facilities in Houston, Texas and Wilmington, Delaware, and relocating the manufacturing to its plants in Dayton, Texas and Hazleton, Pennsylvania, respectively. Operations at the leased Houston facility ceased in December 2010 and the Wilmington facility is expected to be closed by the end of March 2011. The annualized cost savings from the plant consolidations is expected to be approximately $5.0 million. The Company has also implemented staffing reductions across its sales, administration and manufacturing support functions to address the redundancies resulting from the Ivy acquisition. The annualized cost savings from the staffing reductions is expected to be approximately $4.0 million.

The $4.4 million of restructuring charges recorded during the quarter include asset impairment charges to write down the carrying value of long-lived assets related to the plant closures and decommissioning of equipment ($2.9 million); employee separation costs associated with the plant closures and other staffing reductions ($1.0 million); and future lease obligations for the closed Houston facility ($0.5 million). The Company currently expects to incur approximately $2.0 million of additional restructuring charges for equipment relocation and employee separation costs, and approximately $0.4 million of additional acquisition-related costs over the remainder of the fiscal year.

Outlook

Commenting on the business outlook for the balance of fiscal 2011, H.O. Woltz III, Insteel’s president and CEO, said, “We expect demand for concrete reinforcing products to remain at depressed levels during our second fiscal quarter due to the continued softness in our construction end markets and the usual seasonal weakness. Despite the anemic demand environment, prices for hot-rolled steel wire rod, our primary raw material, have surged higher since December driven by escalating scrap costs for steel producers. Although we have announced price increases to recover these additional costs in our markets, the eventual net impact on margins is uncertain at this time.

As we move into the second half of the fiscal year, we expect increasing contributions from the Ivy acquisition through the anticipated operational synergies and the completion of our transition and integration activities. We are pleased with the progress that has been made thus far and look forward to realizing the improved earnings power that we believe we have put into place as our markets gradually rebound.”

Conference Call

Insteel will hold a conference call at 10:00 a.m. ET today to discuss its first quarter 2011 financial results. A live webcast of this call can be accessed on Insteel’s website at http://investor.insteel.com/ and will be archived for replay until the next quarterly conference call.
