INSTEEL INDUSTRIES REPORTS SECOND-QUARTER FINANCIAL RESULTS

MOUNT AIRY, N.C., April 19, 2007 — Insteel Industries, Inc. (Nasdaq: IIIN) today announced financial results for the second quarter ended March 31, 2007. Earnings from continuing operations for the quarter were $4.9 million, or $0.27 per diluted share compared with $7.8 million, or $0.42 per diluted share for the same period last year. Including the results of discontinued operations, net earnings were $4.9 million, or $0.27 per diluted share compared with $7.4 million, or $0.40 per diluted share in the prior year. Net sales for the second quarter decreased 6.3% to $74.8 million from $79.8 million last year. Shipments decreased 6.4% while average selling prices increased 0.2%.

For the six-month period ended March 31, 2007, earnings from continuing operations were $10.9 million, or $0.59 per diluted share compared with $15.9 million, or $0.85 per diluted share in the prior year. Including the results of discontinued operations, net earnings were $10.7 million, or $0.58 per diluted share compared with $15.1 million, or $0.81 per diluted share in the prior year. Net sales for the six-month period decreased 7.0% to $144.5 million from $155.4 million last year. Shipments decreased 7.4% while average selling prices increased 0.4%.

“Considering the continued weakness in housing-related demand, escalating raw material costs and adverse weather conditions that we experienced in certain of our markets, we are pleased with Insteel’s financial results for the second quarter,” said H.O. Woltz III, Insteel’s president and chief executive officer. “We also faced difficult year-over-year comparisons in view of the exceptionally strong prior year results, which represented record sales and earnings for our second fiscal quarter facilitated by the unusually mild weather and extended construction season. Gross margins for the quarter narrowed to 16.5% from 21.3% a year ago due to the reduction in shipments, lower spreads between average selling prices and raw material costs, and higher unit conversion costs resulting from reduced operating schedules.

“Business conditions improved as we progressed through the quarter with March shipments rising 7% from the prior year level — the first month this fiscal year that we’ve posted a year-over-year increase. With the demand outlook more favorable heading into our busy season, we recently announced price increases across all of our product lines to offset the recent upward trend in raw material costs which should favorably impact our third-quarter results. Substantial progress was also made during the quarter in ramping up the Tennessee prestressed concrete strand (‘PC strand’) expansion and the new engineered structural mesh (‘ESM’) line in our North Carolina facility. Going forward, we expect both projects to generate increasing contributions from a volume and operating cost standpoint.”

Operating activities of continuing operations used $10.0 million of cash during the second quarter while providing $3.0 million in the year-ago period due to the year-over-year changes in net working capital together with the decrease in earnings. Net working capital used $15.7 million of cash in the current year quarter compared with $5.0 million in the prior year primarily due to the $14.6 million decrease in accounts payable and accrued expenses in the current year. This decrease was driven by payments related

to higher raw material purchases made during the first quarter and early in the second quarter in anticipation of future price increases. As a result of the cash used by operating activities and the funding requirements for capital expenditures and cash dividends, the Company had $4.3 million of borrowings outstanding on its revolving credit facility as of the end of the quarter.

Capital expenditures for 2007 are currently expected to total $18.0 million and decline to a range of $3.0 to $5.0 million per year beginning in 2008 following the completion of the expansions and equipment upgrades in the Company’s PC strand and ESM businesses. The actual timing of these expenditures as well as the amounts are subject to change based on adjustments in the project timelines, future market conditions, the Company’s financial performance and additional growth opportunities that may arise.

“We expect to start up the new ESM production line in our Texas facility during the fourth fiscal quarter of 2007, following the anticipated receipt of the equipment this quarter,” commented Woltz. “With ESM overwhelmingly used in nonresidential construction applications, the timing of the ramp-up appears to be favorable and should be unaffected by the weakness in the housing market.”

The Company did not repurchase any shares of its outstanding common stock during the second quarter under its previously announced stock repurchase program. As of March 31, 2007, the Company was authorized to buy back up to an additional $25.0 million of its shares over the remaining term of the program, which runs through January 5, 2008. Repurchases may be made from time to time in the open market or in privately negotiated transactions subject to market conditions, applicable legal requirements and other factors. Insteel is not obligated to acquire any particular amount of common stock and the program may be suspended at any time at the Company’s discretion.

Commenting on the outlook for the remainder of fiscal 2007, Woltz said, “Although we are encouraged by the recent acceleration of business activity, at this point it is unclear whether the upturn is driven by customer anticipation of future price increases or the beginning of a sustainable upward trend above the usual seasonal improvement. Market conditions remain mixed. The favorable trends for nonresidential construction, which drives the majority of our revenues, are expected to continue while it has become increasingly unlikely we will see much improvement in the housing-related portion of our business before the end of the year.

“Raw material costs are on the rise and our ability to pass these increases through in our markets will ultimately depend upon the strength of demand and competitive factors, particularly in those segments of our PC strand business that are subject to import competition. Despite these challenges, we expect significant improvement in Insteel’s financial performance during the second half of the year.”

Conference Call

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