WSI Industries Reports Second Quarter Results

March 25, 2009—Minneapolis, MN—WSI Industries, Inc. (Nasdaq: WSCI) today reported sales for its fiscal 2009 second quarter ending March 1, 2009 of $4,001,000, a 38% decrease versus the prior year amount of $6,422,000. Year-to-date sales for the six months ended March 1, 2009 totaled $10,037,000 versus $12,396,000 in the prior year. The Company incurred a net loss for the fiscal second quarter of $307,000 or $.11 per share versus net income of $433,000 or $.15 per share in the prior year quarter. For the year-to-date period ended March 1, 2009, the Company experienced a net loss of $206,000 or $.07 per share versus the prior year’s net income of $819,000 or $.29 per share.

Michael J. Pudil, president and chief executive officer, commented: “The economic recession took a toll on our fiscal 2009 second quarter revenues as we experienced sales declines in all sectors of our business. December and January were especially hard hit with deliveries being deferred from our two main industries, recreational vehicles and energy. With the shortfall in revenue, we experienced our first quarterly loss in almost 5 years.” Pudil went on to say: “While it is uncertain when the overall recovery will occur in the country, our current customer schedules for the second half of fiscal 2009 project a rebound in sales. During this period, we will be working to streamline and reduce costs in an effort to return WSI to profitability without impacting revenue or the ability to capture new business.” Pudil concluded: “Even during this troubling time, WSI has been able to secure additional long term agreements, new multiyear purchase orders, and new parts for existing programs. We therefore remain confident about WSI’s long-term future. We have a strong balance sheet, state of the art equipment and facilities, and have good relationships with customers who are leaders in their industries. We are continually working and quoting on new business opportunities and believe that we will be in a stronger position when the economy starts to improve.”
