Exhibit 99.1

 Greatbatch, Inc. Reports Record Quarterly Sales; Increases Sales and Earnings
                               Guidance for 2006

    CLARENCE, N.Y.--(BUSINESS WIRE)--July 26, 2006--Greatbatch, Inc.
(the "Company") (NYSE: GB) today reported its results for the second
quarter ended June 30, 2006.

    Business Highlights


    --  Achieved record quarterly sales for:

        --  Total Company - sales of $70.6 million, up 11% from $63.5
            million in the second quarter of 2005.

        --  Implantable Medical Components - sales of $59.8 million,
            up 9% from $54.8 million in the second quarter of 2005.

            --  2005 sales included approximately $3 million of
                additional revenue related to customer field actions,
                primarily impacting ICD batteries and capacitors.
                Adjusting for this effect, sales increased by 15%.
            --  The increase was primarily due to sales of new
                assembly products and continued growth in coated
                electrodes.

        --  Electrochem Commercial Power - sales of $10.8 million, up
            24% led by continued strength in the oil and gas market.

    --  Diluted Earnings Per Share (EPS) under U.S. Generally Accepted
        Accounting Principles (GAAP) were $0.21. Adjusted EPS,
        excluding move-related expenses, severance costs and
        stock-based compensation under FAS123R, were $0.32. (See Table
        A for reconciliation to GAAP), which compares to $0.33 in the
        second quarter of 2005. The current quarter's results reflect
        the impact of the planned increase in net RD&E costs of $2.5
        million (pre-tax).

    --  Facilities update - The initial planned shield assembly moves
        have been completed with all quality and financial goals
        achieved. The final move of the filtered feedthrough product
        line from Carson City is scheduled to be completed during the
        third quarter of 2006. The move of the Columbia feedthrough
        facility is on-going. The construction of the manufacturing
        area is complete and the class 10,000 clean room is in the
        process of being validated. This move is scheduled for
        completion in mid-2007, as originally planned.

    --  Raising 2006 full year financial guidance as follows:
        --  Full year 2006 projected sales are being increased to a
            range of $270 - $280 million.
        --  Full year 2006 EPS estimates are being increased to a
            range of $0.70 - $0.83 from the previous guidance numbers
            of $0.60 - $0.70.

    Edward F. Voboril, Chairman and Chief Executive Officer commented,
"Our second quarter results reflect the continued strength across both
our medical and commercial product lines. This quarter's sales
performance came on the heels of a first quarter record. Despite the
volatility in our markets, our growth continues, which reflects our
success in increasing our competitive position in the marketplace. A
key driver in leveraging our earnings growth is the successful
completion of our various consolidation initiatives. I'm pleased to
report that to date, we continue to meet both our own internal
facility consolidation goals as well as the requirements of our
customers. These operating initiatives, combined with our new product
investments and extensive search for new market opportunities, has us
strategically positioned for long-term growth," Voboril concluded.

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


                                               2006     2005      %
                                             2nd Qtr. 2nd Qtr. Change
- ---------------------------------------------------------------------
Gross Profit(1)                              $26,777  $24,161    +11%
Gross Margin                                   37.9%    38.0%

SG&A Expenses                                 $9,865   $8,481    +16%
SG&A Expenses as % of Sales                    14.0%    13.4%

RD&E Expenses, net                            $6,142   $3,657    +68%
RD&E Expenses, net as % of Sales                8.7%     5.8%

Operating Income                              $7,127   $8,022    -11%
Operating Margin                               10.1%    12.6%

Effective Tax Rate                             34.5%    30.0%

    (1) Gross profit 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 below the gross profit
calculation.
    Gross margin 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 research and development programs ($1.5
million), coupled with lower customer reimbursements for development
charges in the current quarter compared to the second quarter last
year ($1.0 million). RD&E as a percentage of sales is expected to
continue to increase to a range of 9% to 9.5% for the full year 2006.

    Outlook
    Considering the performance of the first two quarters, the Company
is revising its guidance as follows (dollars in millions, except per
share amounts):
