    CLARENCE, N.Y.--(BUSINESS WIRE)--April 26, 2007--Greatbatch, Inc.
(the "Company") (NYSE: GB) today reported its results for the first
quarter ended March 30, 2007.

    Business Highlights

    --  Total Company - record sales of $76.9 million, an increase of
        13% compared to $68.1 million in 2006.

         $65.2 million, an increase of 13% compared to $57.6 million
         in 2006, driven by growth of ICD capacitors, feedthroughs and
         assembly products partially offset by a decrease in ICD
         battery sales.
      -- Electrochem Commercial Power ("ECP") - sales of $11.7
         million, an increase of 11% compared to $10.5 million in
         2006, driven by growth in oil & gas, pipeline inspection, and
         military products.


    --  Earnings per share increased by 54% to $0.43, inclusive of an
        $0.11 gain on the exchange of $118 million of convertible
        debentures.

    --  Final production run for Carson City plant is scheduled for
        June '07.

    --  Columbia, Maryland shutdown scheduled to be completed by the
        third quarter of 2007.

    --  Completed the acquisition of Biomec, Inc. for $11.4 million on
        April 3, 2007.

    --  ECP expansion on track for completion in mid - 2008.

    --  Completed the exchange of $118 million of the existing $170
        million convertible subordinated debentures outstanding.
        Issued an additional $80 million of new convertible
        subordinated debentures and received cash of $74 million (net
        of fees and discount).

    --  Received commitments for a new revolving bank credit facility
        of $235 million with the ability to expand to $335 million.

    Commenting on the first quarter results, Thomas Hook, President &
Chief Executive Officer, said: "I'm very pleased with the start to the
new year. We achieved broad-based sales growth in our medical and
commercial segments. Our Medical Power team did a great job in
responding to the surge in ICD capacitor demand we experienced in the
first quarter. On the commercial side, we continue to see double-digit
growth rates due to market growth and share gains.

    "On a strategic front, we completed a number of important
transactions in the first quarter that are key to fuel our continued
growth. First, we successfully exchanged approximately 70% of our
existing subordinated notes and concurrently issued an additional $80
million of new convertible debentures. Second, we have received
commitments to replace our existing revolving credit line with a new
$235 million facility, which combined with our existing cash and
investments, gives us over $400 million of cost-effective liquidity to
fund our organic and in-organic growth strategies. The exchange
offering and the 2nd quarter sale of an investment, combined with
operations as planned have allowed us to increase our guidance for the
year.

    "In April we completed the acquisition of Biomec, Inc., a medical
device design and engineering company, located in Cleveland, Ohio.
With the addition of Biomec we are now in position to offer our
customers a suite of value add services that include system design and
integration, rapid prototyping and assembly services," Hook concluded.

Operating Margin                             13.8%     14.8%

Effective Tax Rate                           32.5%     34.5%


    The cost of sales percentage increased from last year due to
unfavorable product mix and lower ICD battery production volume in the
current quarter.

    The increase in SG&A expenses is primarily due to legal fees,
non-cash directors' fees, executive transition costs and sales &
marketing costs.

    The increase in net RD&E expenses is primarily due to a planned
increase in spending on new development programs.

    The other operating expense in the current quarter consists of:



- -- Carson City and Columbia closures/relocations      $ 1.7 million
- -- ECP building expansion                             $ 0.1 million
- -- Asset dispositions and other                      ($ 0.3) million


    As a result of an estimated increase in R&D tax credits and the
Qualified Production Activities Deduction for 2007, the effective tax
rate for 2007 is now expected to be approximately 32.5%.
