Exhibit 99.1 [HUBBELL LOGO] Date: April 13, 2005 NEWS RELEASE For Release: IMMEDIATELY - -------------------------------------------------------------------------------- Hubbell Incorporated 584 Derby-Milford Road P. O. Box 549 Orange, CT 06477 203-799-4100 Contact: Thomas R. Conlin HUBBELL UPDATES 2005 EARNINGS GUIDANCE ORANGE, CT. (April 13, 2005) -- Hubbell Incorporated (NYSE: HUBA, HUBB) today revised its guidance for earnings per share for its fiscal year ending December 31, 2005. Citing its previous guidance of $2.65-2.95 fully diluted earnings per share provided in a conference call and webcast on January 20, 2005, management now anticipates that EPS will approximate $2.55-2.80. As was announced previously and reaffirmed today, the range does not include $20-30 million, pre-tax, of 2005 restructuring expenses. "Hubbell does not provide quarter-by-quarter projections for sales or profit," said Timothy Powers, Chairman, President, and CEO, "but our experience year-to-date requires revision of our full-year guidance." "The year has begun with a lower level of sales than we had anticipated in the Electrical Segment and specifically in our Lighting business. While sales are marginally higher than last year, product pricing remains difficult versus higher materials costs. Each of our other segments are performing at our expectations," Powers continued, "with notable strength at Power Systems and Industrial Technology. Nonetheless, since Lighting is Hubbell's largest business, the shortfall in operating profit there is expected to bring 2005 EPS below previously published projections." "We remain optimistic that, as non-residential construction and other core markets increase in activity through the remainder of the year, Hubbell will report another year of positive growth in 2005." -continued-

"For the first quarter 2005, we expect reported fully diluted earnings per share to be in the $.44-.47 range which includes approximately $1.9 million, pre-tax, of restructuring expenses related to our lighting operations and approximately $4.6 million, pre-tax, of transactional expenses consisting of legal, accounting, and consulting fees in support of our strategic growth initiatives."
