Thomas & Betts Corporation Reports Fourth Quarter Net Earnings of $0.70 Per Share Excluding Unusual Items

2010 Full Year Earnings Guidance of $2.20 to $2.60 per Share

MEMPHIS, Tenn.--(BUSINESS WIRE)--February 2, 2010--Thomas & Betts Corporation (NYSE:TNB):

NOTE: All financial information and period-to-period references are on a continuing operations basis (excluding discontinued operations) unless otherwise noted. References to E.P.S. are on a diluted basis unless otherwise noted. Information on discontinued operations as well as non-GAAP reconciliations can be found in the attached financial tables.

Thomas & Betts Corporation (NYSE:TNB) today reported results for the fourth quarter and year ended December 31, 2009.

Fourth quarter 2009 net earnings from continuing operations were $37.0 million or $0.70 per share, excluding $0.19 per share in unusual items related to: debt refinancing ($0.08 per share), facility consolidation ($0.04 per share) and intangible asset impairment ($0.07 per share). In the prior-year period, net earnings from continuing operations were $44.2 million, or $0.81 per share, excluding a $0.36 per share impairment charge. Reported net earnings from continuing operations were $27.1 million or $0.51 per share compared to $24.3 million or $0.45 per share last year.

Fourth quarter 2009 net sales were $492.8 million, in line with expectations and down 13.8% compared to the fourth quarter 2008.

“We finished 2009 in a position of strength,” said Dominic J. Pileggi, chairman and chief executive officer. “We delivered strong segment earnings of nearly 19% of sales despite continued weakness in global demand. As a company and as individual businesses, we have responded real-time to the demands of today’s economy while strategically managing for the future. During the quarter, we opened a manufacturing facility in the Middle East and positioned ourselves for continued growth in this region’s key industrial markets. Last week, we announced the acquisition of JT Packard, the leading independent service provider for power quality equipment which enhances our existing service capabilities while offering growth opportunities for our industrial and commercial products portfolio.”

Full year 2009 net earnings from continuing operations were $120.3 million, or $2.27 per share, excluding the previously mentioned fourth-quarter unusual items and a charge for environmental remediation taken in the third quarter. In 2008, net earnings from continuing operations were $198.8 million, or $3.48 per share, excluding a net benefit from unusual items of $1.31 per share. Reported net earnings from continuing operations were $107.9 million or $2.04 per share compared to $273.7 million or $4.79 per share last year.

Net sales were $1.9 billion for the full year 2009, down 23.2% compared to 2008.

SEGMENT HIGHLIGHTS:

Consolidated segment earnings were $93.2 million or 18.9% of sales for the fourth quarter 2009, compared to $113.9 million or 19.9% of sales in 2008. For the full year 2009, segment earnings were $335.8 million or 17.7% of sales. In 2008, segment earnings were $486.8 million or 19.7% of sales.

Electrical:

Fourth quarter 2009 Electrical sales were $391.3 million, down 15.8% compared to the prior-year period. For the full year, sales decreased 26.1% to $1.6 billion. The decrease is due to weak global market conditions and lower volumes across virtually all market segments and geographies.

Electrical segment earnings were $75.7 million, or 19.3% of sales, in the fourth quarter and $270.2 million, or 17.4% of sales, for the full year 2009. This compares to $90.6 million or 19.5% in the fourth quarter and $416.7 million or 19.8% of sales for the full year 2008. The full year earnings decline reflects the negative impact of lower sales and production volumes and a stronger U.S. dollar for the majority of the year.

Steel Structures:

Fourth quarter 2009 Steel Structures sales were $66.6 million, down slightly compared to the prior-year period. Sales for both the current and prior-year quarters were positively impacted by delayed shipments of approximately $6 million from the preceding quarter. Full year 2009 sales were $234.5 million, up slightly year over year.

Steel Structures segment earnings were $10.8 million, or 16.2% of sales, in the fourth quarter and $47.4 million, or 20.2% of sales, for the full year 2009. This compares to $14.7 million, or 21.8% of sales, in the fourth quarter and $44.3 million, or 19.1% of sales, for the full year 2008.

HVAC:

Fourth quarter and full year 2009 HVAC segment sales were $34.9 and $109.9 million, a decline of 10.8% and 21.0% respectively.

HVAC earnings were $6.7 million, or 19.2% of sales, in the fourth quarter and $18.2 million, or 16.6% of sales, for the full year 2009. This compares to $8.5 million, or 21.9% of sales, in the fourth quarter and $25.7 million, or 18.5% of sales, for the full year 2008. The decline in both the quarter and full year earnings as a percent of sales is due to lower sales and production volumes.

BALANCE SHEET/LIQUIDITY HIGHLIGHTS:

Free cash flow from operations was $246.8 million (excluding a voluntary pension plan contribution of $50 million) for the full year 2009, with a notable strong performance in the fourth quarter. Focused and effective working capital management again drove the strong cash performance. At year end 2009, working capital was 13.6% percent of sales.

During the quarter, Thomas & Betts issued $250 million of 5.625% senior notes due 2021 and used the net proceeds to retire $125 million of 7.25% notes due 2013 and repay $95 million of outstanding indebtedness on the company’s revolving credit facility. Total debt to total capitalization was 32.3% at year-end 2009, an improvement from 36.6% at year-end 2008, respectively. The company ended 2009 with $479 million in cash and had over $380 million of availability under its existing credit agreements.

FULL YEAR 2010 GUIDANCE:

“2009 was a year filled with challenges – challenges against which we executed aggressively and managed strategically,” said Pileggi. “We responded quickly to the downturn in demand, reducing headcount, cutting expenses and remaining disciplined in managing pricing. At the same time, we continued to invest in our brands and businesses, maintained our focus on working capital and realigned our debt structure to extend its duration at favorable rates. As a result, we entered 2010 with an enhanced cost structure, a strong and flexible balance sheet and a focus on growth.”

“While the major global economies appear to have stabilized, we remain cautious on the macro environment,” continued Pileggi. “We anticipate little year-over-year change in our full year consolidated sales as pockets of growth in certain markets will be offset by declines in others,” “We are currently targeting full year 2010 net earnings from continuing operations in the range of $2.20 to $2.60 per share.”
