                    Thomas & Betts Corporation Reports First
                             Quarter 2007 Earnings

                       Sales Increase 7 Percent;

                    Earnings per Share $0.63 Including $0.08
                       Charge Related to Legal Settlement


    MEMPHIS, Tenn.--(BUSINESS WIRE)--April, 23, 2007--Thomas & Betts Corporation
(NYSE: TNB) today reported first quarter 2007 net earnings of $37.1
million including the negative impact of $7 million ($0.08 per share)
of pre-tax expenses related to a legal settlement. This compares to
net earnings of $38.8 million in the first quarter 2006. Including the
$0.08 per share charge, 2007 first quarter earnings were $0.63 per
diluted share. This compares to $0.62 per diluted share in the first
quarter 2006.

    First quarter 2007 net sales rose 7.4 percent to $474.6 million,
compared to $441.8 million in the prior-year period. Price increases
to offset higher material and energy costs and volume improvements
contributed to the sales increase. Foreign currency benefited sales by
approximately $5 million in the quarter.

    "2007 started out strong for Thomas & Betts. Demand remains
positive in industrial and utility markets and is beginning to
strengthen in commercial construction markets," said Dominic J.
Pileggi, chairman and chief executive officer. "We continue to execute
as planned and again improved operating margins in each of our
business segments."

    First quarter 2007 gross margin was approximately 31 percent of
sales, in line with the prior-year period. The company continued to
successfully offset higher material and energy costs with increased
selling prices.

    Including the $7 million legal charge, selling, general and
administrative (SG&A) expense was $87.3 million, or 18.4 percent of
sales, in the first quarter 2007. This compares to 17.8 percent of
sales in the prior-year period. Earnings from operations were $57.5
million in the quarter, or 12.1 percent of sales, compared to $57.8
million, or 13.1 percent of sales, last year. As a percent of sales,
both SG&A and earnings from operations were negatively impacted by 1.5
percentage points as a result of the legal settlement.

    The effective tax rate increased to 31 percent in the first
quarter 2007, up from 29 percent in the prior-year period reflecting a
net increase in U.S. income taxes.

    SEGMENT RESULTS

    During the first quarter 2007, the company began to report
corporate expenses related to legal, finance and administrative costs
separately from business segment results. Management believes this
change provides improved transparency into the underlying operating
trends in the business segments. 2006 results have been revised to
reflect this change. First quarter 2007 corporate expense includes the
$7 million legal charge.

    Electrical segment sales were $389.2 million in the first quarter,
up 8.8 percent compared to the first quarter 2006. Higher selling
prices driven by higher material and energy costs contributed
significantly to the sales growth. Solid demand in industrial,
commercial construction and utility distribution markets also
contributed to the sales improvement. Foreign currency benefited sales
by $4 million in the first quarter 2007.

    Electrical segment earnings were $64.9 million in the quarter, up
11.4 percent compared to the first quarter 2006. As a percent of
sales, segment earnings were 16.7 percent, up from 16.3 percent
reflecting slightly higher sales volume.

    Sales in the Steel Structures segment were $53.0 million in the
quarter, similar to the prior-year period. Steel Structures segment
earnings increased 6.8 percent to $8.9 million, or 16.8 percent of
sales, reflecting improved project mix in 2007 compared to 2006.

    HVAC segment sales increased approximately four percent to $32.4
million in the first quarter 2007. Segment earnings were $4.7 million,
up 13 percent from the prior-year period. As a percent of sales,
segment earnings improved to 14.6 percent in the first quarter 2007,
compared to 13.3 percent of sales in same period last year. The
earnings improvement reflects continued cost control and higher sales.

    BALANCE SHEET HIGHLIGHTS

    The company ended the first quarter 2007 with approximately $310
million in cash and $388 million in total debt. During the first
quarter 2007, the company repurchased 1.8 million shares of common
stock at a cost of approximately $94 million. The share repurchase
activity had no net effect on earnings per share in the quarter.

    2007 DIRECTIONAL GUIDANCE

    "We saw demand strengthen as the quarter progressed and continue
to expect solid sales growth in the mid-single-digit range for 2007,"
said Pileggi. "Despite the negative impact of the $0.08 per share
legal settlement, we are reaffirming our earnings guidance of $3.05 to
$3.15 for the full year 2007."
