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.

OutlookLemaitre 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.
