       Greatbatch, Inc. Reports Fourth Quarter and Full-Year 2006 Results

                   Sales for Year Grow by 12% to Record Level

    CLARENCE, N.Y.--(BUSINESS WIRE)--Feb. 8, 2007--Greatbatch, Inc.
(the "Company") (NYSE: GB) today reported its results for the fourth
quarter and year ended December 29, 2006.

    2006 Highlights

    --  Achieved record sales for:



      -- Total Company - sales of $271 million, an increase of 12%
         compared to $241 million in 2005

      -- Implantable Medical Components ("IMC") - sales of $227
         million, an increase of 9% compared to $208 million in 2005

      -- Electrochem Commercial Power ("ECP") - sales of $44 million,
         an increase of 33% compared to $33 million in 2005


    --  Met all of the milestones for the consolidation of feedthrough
        manufacturing from Columbia, Maryland to Tijuana, Mexico and
        medical research and development into the Technology
        Development Center in Clarence, New York.

    --  Received ISO 13485 Certification for our Tijuana, Mexico
        facility.

    --  Executed a plan in November 2006 for consolidating our
        corporate and business unit organization structure.

    --  Operating Income, excluding selected charges and incremental
        FAS 123R expenses, increased by 24% to $44 million compared to
        $35 million in 2005 (See Table B for reconciliation to GAAP).

    --  Cash and short-term investments increased by $30 million to
        $143 million as of December 29, 2006.

    Results for Quarter

    --  Total Company - sales of $63 million, up 7% from $59 million
        in the fourth quarter of 2005.



      -- IMC - sales of $53 million, up 4% from $51 million in the
         fourth 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 $5 million of additional
            revenue related to customer field actions, primarily
            impacting ICD batteries and capacitors. Adjusting for this
            effect, sales increased by 15%.

      -- ECP - sales of $10 million, up 31% from $7.7 million in the
         fourth quarter of 2005, led by continued strength in the oil
         and gas and telematics markets.


    --  Diluted Earnings Per Share ("EPS") was $0.06. Adjusted EPS,
        which excludes facilities move-related expenses, asset
        dispositions, severance costs associated with November's
        consolidation and incremental stock-based compensation under
        FAS123R, was $0.28 (See Table A for reconciliation to GAAP),
        which compares to adjusted EPS of $0.13 in the fourth quarter
        of 2005.

    Commenting on full-year results, Thomas Hook, Chief Executive
Officer, said: "I am very pleased with the improvements we are seeing
in our operating and financial metrics. Despite a soft underlying ICD
market, we achieved record sales results in both our medical and
commercial segments. We grew faster than our markets by capturing
share and we continue to introduce new product offerings that enhance
our competitive market position. Looking ahead to 2007, we expect
sales growth of 10%, which reflects our confidence to continue to grow
faster than the underlying markets.

    "With respect to our consolidation plan, we are about two-thirds
of the way through our three-year planned initiatives and expect to
conclude these activities in 2007. We continue to make significant
progress and fully anticipate achieving the long-term cost savings
targets. In addition, based on our continued success in growing our
commercial business, we are launching a new initiative to expand our
manufacturing capacity and capabilities for commercial power sources.
We anticipate completing this expansion in early 2008," Hook
concluded.

    4th Quarter Profit & Loss Summary

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



                                     2006         2005          %

Cost of Sales                        $40,747      $40,347         +1%

SG&A Expenses                        $10,594       $7,439        +42%
SG&A Expenses as % of Sales             16.8%        12.6%

RD&E Expenses, net                    $6,163       $5,543        +11%
RD&E Expenses, net as % of Sales         9.8%         9.4%

Operating Income                      $1,132       $1,161         -2%
Operating Margin                         1.8%         2.0%


    The cost of sales percentage improved from last year as lower
manufacturing costs and lower excess capacity costs more than offset
the change in product mix stemming from higher sales of lower margin
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, CEO transition costs and an increased
level of incentive compensation.

    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 fourth quarter of last year.

    The other operating expense in the current quarter consists of:

    --  Carson City and Columbia consolidations/relocations $1.9
        million

    --  Asset dispositions and other $0.1 million

    --  Severance for November 2006 Consolidation $2.5 million
