HUBBELL REPORTS FIRST QUARTER RESULTS;

NET SALES OF $658.1 MILLION AND EARNINGS PER DILUTED SHARE OF $0.82

SHELTON, CT. (April 21, 2011) — Hubbell Incorporated (NYSE: HUBA, HUBB) today reported operating results for the first quarter ended March 31, 2011.

Net sales in the first quarter of 2011 were $658.1 million, an increase of 15% compared to the $570.5 million reported in the first quarter of 2010. Operating income was $83.6 million, or 12.7% of net sales, compared to $65.7 million, or 11.5% of net sales, for the comparable period of 2010. Net income in the first quarter of 2011 was $50.3 million versus $38.6 million reported in the first quarter of 2010. Earnings per diluted share were $0.82 in the first quarter of 2011 compared to $0.64 reported in the first quarter of 2010. Free cash flow (defined as cash flow from operations less capital expenditures) was $31.5 million in the first quarter of 2011 versus $12.8 million reported in the comparable period of 2010.

OPERATIONS REVIEW

Timothy H. Powers, Chairman, President, and Chief Executive Officer said “Our first quarter results were strong, particularly given the commodity cost challenges we faced. Our sales increased 15% with double-digit growth in each of our segments. Our operating margin of 12.7% was up 120 basis points compared to 2010 primarily due to higher volume. As anticipated, we did experience commodity costs headwinds in the quarter. The impact of the higher commodity costs in excess of price realization reduced our operating margins by approximately one percentage point in the first quarter. We announced broad price increases during the quarter but do not expect to fully realize the benefits until later in the year.

“Our incoming orders in the first quarter were modestly higher than we expected, with strength in both of our segments. In our Electrical segment, we experienced broad based higher demand year-over—year compared to a weak first quarter of 2010. The increased demand was led by our industrial products, while U.S. non-residential construction continued to benefit from strong demand for renovation and relight products. The residential market experienced lower demand, impacted by the continued high levels of unemployment and foreclosures as well as a difficult comparison to 2010 which benefitted from the Federal Housing Tax Credit. In our Power segment, we experienced volume increases for both distribution and transmission products compared to the prior year.”

SEGMENT REVIEW

The comments and year-over-year percentages in this segment review are based on first quarter results in 2011 and 2010.

Electrical segment net sales in the first quarter of 2011 increased 14% to $466.1 million compared to $409.3 million reported in the first quarter of 2010. The sales increase was broad based led by demand for industrial products including high voltage test equipment. Compared to the first quarter of 2010, operating income increased 44% to $57.6 million, or 12.4% of net sales. The increase in operating income was due to higher sales partially offset by commodity cost increases.

Hubbell’s Power segment net sales in the first quarter of 2011 increased 19% to $192.0 million compared to $161.2 million reported in the first quarter of 2010. The increase was due to higher demand for both distribution and transmission products. Compared to the first quarter of 2010, operating income increased 2% to $26.0 million, or 13.5% of net sales. The increase in operating income was primarily due to higher sales largely offset by increased commodity costs and higher spending to support growth initiatives, including product and brand development.

SUMMARY & OUTLOOK

Mr. Powers commented “Based on early indications of improving market demand and higher price realization, we are now forecasting sales to increase by 5%-7% for the year. As we have previously mentioned, the sales comparisons versus 2010 are likely to be easier in the first half of the year and become more difficult as the year progresses. We still expect demand for our power products to increase in the mid-single digit range with higher levels of spending for both distribution and transmission products. Our overall industrial market outlook has improved, particularly for our Harsh and Hazardous businesses which are benefitting from higher spending on energy related projects. The non-residential construction market is forecasted to be relatively flat in 2011 while demand for renovation, relight and controls is expected to remain strong. The residential market remains weak and we anticipate this market to be flat to slightly down compared to 2010.”

Mr. Powers concluded “Turning to our operating margin, we expect to benefit from higher sales and improved price realization. We also anticipate that commodity cost increases, including the price of oil, and other inflationary pressures will mitigate much of the benefits. As such, we continue to expect our operating margin will increase by approximately 50 basis points in 2011. The commodity market remains volatile as evidenced by prices for certain types of steel that have increased on average by 30%-40% compared to the fourth quarter of 2010. As always, we are working to offset commodity cost increases through pricing actions but the timing of recovering those costs tends to lag by at least one quarter. We remain confident that we should be able to navigate through these cost challenges to produce record earnings in 2011. Looking beyond the current year, we are excited with the prospect that fully half of our markets, non-residential and residential construction, are expected to return to growth following historic slumps. In addition, we expect strong growth in both utility transmission spending and energy efficient buildings including LED lighting applications.”
