                       Thomas & Betts Corporation Reports
         Second Quarter 2005 Results; Sales Up 13 Percent; E.P.S. $0.47


    MEMPHIS, Tenn.--(BUSINESS WIRE)--July 25, 2005--Thomas & Betts
Corporation (NYSE: TNB) today reported second quarter 2005 net
earnings of $28.4 million, or $0.47 per basic and diluted share, up
42.2 percent from the $20.0 million in net earnings, or $0.34 per
basic and diluted share, reported in the second quarter 2004.
    Sales in the quarter were $418.1 million, up $49.1 million, or
13.3 percent, from the prior-year period. Higher sales volume and
price realization to offset higher material costs contributed
significantly to the sales improvement. Favorable foreign currency
exchange rates accounted for approximately $8 million of the increase.
Earnings from operations were $46.4 million or 11.1 percent of sales
in the quarter just ended. In the second quarter 2004, earnings from
operations were $35.6 million or 9.7 percent of sales.
    "Higher revenue, along with productivity improvements and strong
cash flow, combined to make this a very good quarter for Thomas &
Betts," said Dominic J. Pileggi, president and chief executive
officer. "Earnings from operations were 11 percent of sales in the
second quarter, a significant improvement over last year."
    Pileggi continued, "Each of our business segments improved their
year-over-year performance despite the challenge of higher costs and
modest underlying growth in many of our markets. We are especially
pleased with the excellent performance of our Steel Structures
business, which benefited from continued investment in regional
transmission grids and the additional capacity we acquired earlier
this year."
    The second quarter 2005 gross margin was 28.7 percent of sales,
compared to 29.1 percent in the prior-year period. Higher material
costs in the second quarter 2005 compared to the prior-year period
were offset through a combination of price increases and, to a lesser
extent, productivity improvements.
    Selling, general and administrative (SG&A) expense was $73.6
million, or 17.6 percent of sales, compared to 19.4 percent of sales,
or $71.6 million, in the prior-year period. The improvement in SG&A as
a percent of sales reflects the company's continued focus on closely
managing expenses and the effect of higher sales.
    The effective tax rate in the second quarter of 2005 was 26.3
percent and included a $0.9 million tax benefit resulting from the
favorable completion of a tax audit.

    SEGMENT RESULTS

    Second quarter 2005 sales in the company's Electrical segment were
up 10.0 percent to $342.1 million, compared to $311.0 million in the
second quarter last year. Price realization to offset higher material
costs and higher sales volume contributed significantly to the sales
growth, while favorable foreign currency exchange rates contributed
approximately $8 million. Second quarter 2005 Electrical segment
earnings were up 14.9 percent to $37.4 million, or 10.9 percent of
sales, compared to $32.5 million, or 10.5 percent of sales in the
prior-year period. Higher sales and increased productivity contributed
to the growth in segment earnings.
    Second quarter sales in the Steel Structures segment were $45.6
million, a significant increase over sales of $30.0 million in the
same period last year. Segment earnings more than doubled to $7.2
million or 15.8 percent of sales. This compares to earnings of $2.6
million, or 8.6 percent of sales, in the second quarter 2004.
Investment in regional transmission projects by U.S. electrical
utilities continues to drive the segment's improved performance.
    HVAC segment sales were $30.4 million in the second quarter 2005,
up 8.6 percent from the $28.0 million in sales reported a year ago.
Second quarter 2005 segment earnings were $2.2 million, double the
$1.1 million reported in the same period last year. Improved
productivity and lower expenses drove the earnings improvement.

    YEAR-TO-DATE RESULTS

    For the six months ended June 30, 2005, sales rose $88.3 million,
or 12.2 percent, to $810.3 million compared to $722.0 million in the
first half of 2004. Favorable foreign currency exchange rates
accounted for approximately $15 million of the sales increase.
    Net earnings for the first six months of 2005 were $52.8 million,
or $0.89 per basic and $0.87 per diluted share. This compares to net
earnings of $35.6 million, or $0.61 per basic and $0.60 per diluted
share for the first six months of 2004.
    Cash flow from operations improved significantly in the first half
of 2005, driven primarily by improved operating earnings and sound
inventory management. Thomas & Betts ended the second quarter 2005
with $369.8 million in cash and cash equivalents.

    2005 DIRECTIONAL GUIDANCE

    "Based on our strong second quarter results, we have revised our
2005 guidance and now believe that earnings per diluted share will be
between $1.77 and $1.82 for the full year 2005," said Pileggi.
