Woodhead Industries Reports Fiscal Second Quarter Results
Income From Operations Up 57%; Net Income Up 129%

DEERFIELD, IL – April 27, 2006 – Woodhead Industries, Inc., (NASDAQ: WDHD) today announced financial results for its fiscal second quarter ended April 1, 2006. The Company reported second quarter revenue of $59.0 million, up 4.7% (7.3% in constant dollars), compared to the same period last year. Income from operations totaled $4.9 million, up 56.9% from the second quarter of 2005. Net income increased 129.3% to $3.0 million, or $0.25 per diluted share for the 2006 second quarter, compared to net income of $1.3 million, or $0.11 per diluted share for the same period in 2005.

Philippe Lemaitre, Woodhead Industries’ Chairman and Chief Executive Officer, commented, “Our second quarter results provide evidence that our sales and marketing initiatives and cost management efforts are paying off. Sales were at the high end of our guidance and earnings exceeded our expectations. Performance in our Electrical segment was particularly strong, as increased volumes and diligent cost management led to significantly improved profitability. We were also pleased with performance in our North American Connectivity segment, which registered another quarter of solid revenue growth.”

In the Connectivity segment, sales were $43.5 million, up 2.4% (5.9% in constant dollars) from the second quarter of 2005, with foreign exchange negatively impacting the year-over-year comparison. Income from operations totaled $3.0 million, compared to $2.3 million last year. North American Connectivity revenue growth remained strong, increasing 9.1% during the quarter. Connectivity segment operating income improved 32.2% primarily due to higher volume levels and cost control.

Electrical segment revenue increased 11.5% to $15.5 million, as compared to $13.9 million for the second quarter of 2005. Income from operations was $2.8 million, up 79.3% from $1.6 million during the same period last year. The substantial increase in Electrical segment profitability is attributable to higher volumes, operational improvements and cost control.

Outlook
Lemaitre noted, “Our positive outlook for the remainder of the year is tempered by the start-up of a new ERP system in North America. We are being cautious and currently anticipate that revenues during the second half of our 2006 fiscal year will be in a range of $115 to $118 million, with earnings per share of $0.42 to $0.45. This performance would result in full year revenues of $227 to $230 million, and earnings per share of $0.85 to $0.88, which is up from our previous full year earnings guidance of $0.79 to $0.85 as a result of our strong second quarter performance.”
