OPERATIONS REVIEW

David G. Nord, President and Chief Executive Officer, said, “Hubbell performed well in the fourth quarter as our businesses remained focused on executing through mixed market conditions. Our sales grew 7% while earnings per diluted share increased 15% compared to the fourth quarter of 2012. I am proud of the organization’s ability to close out 2013 on such a strong note and we are off to a good start in 2014 with three acquisitions already completed in the month of January. These deals will add approximately $45 million in annual revenues and demonstrate our continued commitment to growing the enterprise by adding strategically attractive brands to the portfolio.”

Mr. Nord added “In reviewing the full year results, Hubbell delivered a solid year of operational performance. Our entire team’s commitment to productivity and operational excellence enabled the organization to reach a record level of operating profit. In addition, our continued strong cash flow generation allowed us to create value through a combination of dividends, acquisitions and share repurchases. During 2013, the dividend was increased 11% and we spent over $125 million on a combination of acquisitions and share repurchases. In addition, we increased our capital expenditures by 20% to support growth and productivity initiatives. These actions, along with our strong financial performance, helped Hubbell increase total shareholder return.”

SEGMENT REVIEW

The comments and year-over-year comparisons in this segment review are based on fourth quarter results in 2013 and 2012.

Electrical segment net sales in the fourth quarter of 2013 increased 12% to $585.2 million compared to $521.4 million reported in the fourth quarter of 2012. Acquisitions added 5% to sales in the quarter with the remainder of the increase being primarily driven by higher shipments of residential products and high voltage test equipment. Compared to the fourth quarter of 2012, operating income increased 27% to $86.1 million, or 14.7% of net sales. The increase in operating income was primarily due to the benefit of higher volume and lower costs.

Hubbell’s Power segment net sales in the fourth quarter of 2013 were $221.4 million compared to $231.1 million reported in the fourth quarter of 2012. The sales were impacted by weaker transmission spending and lower storm related shipments. Compared to the fourth quarter of 2012, operating income decreased 6% to $40.1 million. Operating margin in the fourth quarter of 2013 was 18.1%, compared to 18.4% reported in the comparable period of 2012. The decrease in operating margin was primarily due to lower volume partially offset by productivity.

SUMMARY & OUTLOOK

Mr. Nord commented, “As I reflect back on our performance in 2013, I am very proud of the Hubbell team’s accomplishments. During the past year, our leadership team spent a significant amount of time and energy building the foundation for a One Hubbell strategy. We made a lot of progress and enjoyed several early successes with this new approach. I am confident this strategy should result in long-term benefits to the Company, and further enhance shareholder value.”

Mr. Nord concluded, “Turning to 2014, third party forecasts for our end markets suggest a better environment than we experienced in 2013. We expect the non-residential market for new construction to improve, the industrial markets to expand and the residential market to remain strong. The utility market is expected to remain challenging in the near term where overall demand is anticipated to be flat. The combination of the end market growth and our already completed acquisitions should result in sales increasing by approximately five to six percent. From a profitability perspective, we plan to expand our operating margins by approximately 20 to 30 basis points. The tax rate is expected to increase to approximately 32.5%, which excludes any benefit from the R&D Tax Credit. We also plan to leverage our strong financial position to enhance shareholder value through capital deployment with particular emphasis on acquisitions. This puts us in good position to continue to build upon the positive momentum created in the past year.”
