      Greatbatch, Inc. Reports Third Quarter Sales and Earnings


    CLARENCE, N.Y.--(BUSINESS WIRE)--Oct. 25, 2006--Greatbatch, Inc.
(the "Company") (NYSE: GB) today reported results for the third
quarter ended September 29, 2006.

    Business Highlights

    --  Total Company - sales of $69.3 million, up 11% from $62.4
        million in the third quarter of 2005.

        --  Implantable Medical Components - sales of $57.0 million,
            up 5% from $54.1 million in the third quarter of 2005.

            --  The increase was primarily due to sales of new
                assembly products and continued growth in coated
                electrodes and molded components.

            --  2005 sales included approximately $3 to $5 million of
                additional revenue related to customer field actions,
                primarily impacting ICD batteries and capacitors.
                Adjusting for this effect, sales increased by
                approximately 14%.

        --  Electrochem Commercial Power - record sales of $12.3
            million, up 49% from $8.3 million in the third quarter of
            2005, led by continued strength in the oil and gas and
            seismic markets. Approximately $2 million of the increase
            was due to customer inventory stocking and seasonality in
            the seismic market.

    --  Diluted Earnings Per Share (EPS) under U.S. Generally Accepted
        Accounting Principles (GAAP) were $0.15. Adjusted EPS,
        excluding facilities move-related expenses, asset dispositions
        and stock-based compensation under FAS123R, were $0.39 (See
        Table A for reconciliation to GAAP), which compares to $0.28
        in the third quarter of 2005.

    --  Facilities update

        --  The final closure of the Carson City facility was delayed
            to accommodate pending customer regulatory approval.

        --  The move of the Columbia facility is on-going. The
            construction of the class 10,000 clean room is complete
            and validated; manufacturing equipment for the first
            manufacturing line is installed and going through
            installation qualification. This move is scheduled for
            completion in mid-2007, as originally planned.

        --  The Tijuana facility has been recommended for ISO
            13485:2003 certification. This is the internationally
            recognized standard for medical device development and
            manufacturing, which acknowledges that the facility meets
            medical device quality standards.

    --  Maintaining 2006 Guidance as follows:

        --  Full year 2006 projected sales range of $270 - $280
            million

        --  Full year 2006 Adjusted EPS estimates range of $1.18 -
            $1.30

    Thomas Hook, President and Chief Executive Officer commented, "I
am very pleased with our third quarter results. We have delivered six
consecutive quarters of double-digit top-line growth, during a period
which can be characterized as uncertain in terms of the ICD
marketplace. Our growth demonstrates the multiple levers we have to
drive our performance. These growth catalysts include market share
penetration, new product introductions, international expansion, a
robust commercial business and an emerging neurostimulation market
opportunity. Our multi-faceted strategy continues to position the
Company to achieve our long-term goal of growing faster than the
markets we participate in. Looking to 2007, our early indications
suggest our top-line growth should be approximately 10%," Hook
concluded.

    Profit & Loss Summary

    The following table summarizes selected information derived from
the condensed consolidated statement of operations for the third
quarters in 2006 and 2005 (dollars in thousands):



                                          2006       2005        %

Cost of Sales(1)                         $43,657    $39,145      +12%
Cost of Sales as % of Sales                 63.0%      62.8%

SG&A Expenses                             $9,311     $8,842       +5%
SG&A Expenses as % of Sales                 13.4%      14.2%

RD&E Expenses, net                        $6,022     $5,124      +18%
RD&E Expenses, net as % of Sales             8.7%       8.2%

Operating Income                          $4,065     $1,429     +184%
Operating Margin                             5.9%       2.3%

Effective Tax Rate                          24.3%      30.0%


    (1) Cost of sales in 2005 has been revised to include the effect
of amortization of intangible assets of $1.0 million, which was
previously included in operating expenses.

    The cost of sales percentage remained relatively unchanged from
last year as lower manufacturing costs offset unfavorable product mix
stemming from higher sales of assembly products and lower medical
battery sales volume.

    The increase in SG&A expenses is primarily due to the expensing of
stock options under FAS123R.

    The increase in net RD&E expenses is primarily due to a planned
increase in spending on new development programs, coupled with lower
customer reimbursements for development charges in the current quarter
compared to the third quarter last year.

    The increase in the operating margin is primarily due to lower
costs associated with the facility moves and higher sales volume.

    The decrease in the effective tax rate from 30.0% to 24.3% is a
result of adjusting the income accounts to reflect the filing of the
2005 income tax returns. The year-to-date, expected fourth quarter and
full year effective tax rate is 32.5%.

Company is updating its full year guidance as follows (dollars in
