(HUBBELL LOGO) Date: April 20, 2006 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 REPORTS FIRST QUARTER SALES UP 18%, EARNINGS OF $.65 PER DILUTED SHARE ORANGE, CT. (April 20, 2006) -- Hubbell Incorporated (NYSE: HUBA, HUBB) today reported first quarter earnings per share of $.65, an increase of 41% compared to $.46 in the first quarter of 2005. Sales in the quarter were $573.0 million, an increase of 18% compared to sales of $487.6 million reported in the first quarter of 2005. Net income of $39.7 million was 38% higher compared to $28.8 million in the first quarter of 2005. Year-over-year sales and profit comparisons for the quarter include pre-tax expense of $2.7 million or $.03 per diluted share for stock-based compensation for the first quarter of 2006, a pre-tax charge of $4.6 million or $.05 per diluted share for transactional expenses in the first quarter of 2005, and the impact of acquisitions completed in the second and third quarters of 2005 which contributed 3 percentage points of the net sales increase and approximately $.02 of diluted earnings per share. Cash flow from operations was $16.5 million compared to $1.1 million in the first quarter of 2005 primarily due to overall higher net income. Capital expenditures increased quarter-over-quarter primarily due to investments in new products. In addition during the first quarter, the Company repurchased 760,000 shares of its stock for $32.9 million. -continued-

OPERATIONS REVIEW "We are very pleased with our first quarter performance," said Timothy H. Powers, Chairman, President, and Chief Executive Officer. "Most of Hubbell's markets have been strong to start the year and our multi-year initiatives gained traction. This was most apparent at the Power Systems and Industrial Technology Segments where accomplishments in lean manufacturing, low cost sourcing, and acquisitions leveraged positive trends in underlying markets. "Positive market trends were also apparent in our Electrical Segment's markets," Powers added, "as sales rose by 11% and order input increased at an even greater rate. As expected, and as we've noted in recent public presentations, the Segment's margins were lower year-over-year principally in our Wiring Systems and Lighting businesses resulting from production and delivery inefficiencies and product outsourcing. "Important for Hubbell's long-term growth was the third SAP implementation completed in early April. Building on our experience in past `go-lives' - especially the most recent success in the Lighting and Electrical Products businesses - the Power Systems implementation is, thus far, working well. We now have 75% of the Company `live' on the system. The final SAP implementation in our domestic operations is scheduled for October 2006, at Industrial Technology and the remaining Lighting operations." SEGMENT REVIEW Sales for the Electrical Segment were $391.1 million, an increase of 11% while operating income was $31.4 million, comparable to last year. Each of the three businesses in the Segment - Wiring Systems, Electrical Products and Lighting - reported higher sales and double-digit rates of new order input. Each of the three also reported steady progress in addressing specific issues that have lowered profitability. - At Wiring Systems, production and delivery inefficiencies are on track for resolution over the next several months. At the same time, the recently introduced metal raceway line has received good market acceptance and is ahead of plan for sales. - Hubbell Lighting reported volume improvements in both its stock and project Commercial and Industrial fixtures businesses. All five regions of the country reported higher sales. Residential -continued-

fixture volume was also positive year-over-year despite the housing market slowing moderately from its record pace of 2005. Business integration and streamlining activities continued to impact profitability in the quarter. Production transfers as well as office relocations have resulted in costs of duplicate facilities, increased logistics costs, and lower productivity levels. Production transfers are expected to be substantially completed by year-end 2006. - Hubbell Electrical Products continues to contend with material cost increases - steel prices increased again on April 1 - but these operations are effectively managing toward cost/price parity. Selective selling price increases and a focus on internal efficiencies and cost reductions are all contributing. The market for harsh and hazardous application products was especially strong during the quarter. Sales for the Power Systems Segment rose by 34% to $132.3 million, operating income nearly doubled to $20.5 million, and operating margin exceeded 15%. Strong order input across all of the Segment's businesses reflected more robust capital investments by the utility industry. Leveraging that volume growth into substantially higher profitability was one of the Segment's operating achievements. Lean manufacturing advances are helping to eliminate unnecessary capacity internally while effective pricing actions to counter continued cost increases remained in the forefront. The Segment's recent acquisition in Brazil - - Delmar Manufacturing - also contributed to higher year-over-year sales and operating profit. The Industrial Technology Segment added another quarter of growth with sales of $49.6 million up 40% and operating income of $8.7 million up by 78%. Every one of the Segment's diverse businesses reported substantial increases in sales and profit including two acquisitions completed in the second half of 2005 which contributed approximately half of the sales increase. Particular strength was noted in the offshore oil and energy markets and the global high voltage test market. All are expected to exhibit continuing strength. SUMMARY AND OUTLOOK "The quarter exceeded our expectations throughout Hubbell's operations," Powers added. "We anticipated lower margins in the first quarter in our Electrical Segment as we began this year of peak investment and change. The Lighting streamlining, a major new product introduction, and the domestic SAP implementation -continued-

are expected to be substantially completed this year. Each requires considerable investment in time and money. Each should prove to be well worth the effort. "We also expected continued strength in markets served by Power Systems and Industrial Technology, and that was the case. Both Segments are demonstrating their operating efficiencies by reaching our interim strategic goal of 15%+ operating margins. Those results are testimony to the effectiveness of our initiatives. "While the economic environment is generally positive, and our programs are on schedule, much remains to be done in 2006. We have a final domestic SAP implementation, more Lighting streamlining, and continuing challenges in material and energy costs. As a result, we are maintaining our full year 2006 earnings per share guidance in the range of $2.60 to $2.80."
