                  Natus Medical Announces Record 2007
                   Second Quarter Financial Results

    - Company Reports Record Second Quarter Revenue and Earnings

    - Updates 2007 Revenue and Earnings Guidance


    SAN CARLOS, Calif.--(BUSINESS WIRE)--Aug. 2, 2007--Natus Medical
Incorporated (Nasdaq:BABY) today announced financial results for the
three and six month periods ended June 30, 2007.

    For the second quarter ended June 30, 2007, Natus reported revenue
of $28.3 million, representing a 42% increase from $20.0 million in
the comparable quarter of the previous year. The Company reported net
income of $2.3 million, or $0.10 per diluted share, for the second
quarter of 2007, compared with net income of $1.4 million, or $0.07
per diluted share, for the second quarter of 2006.

    For the six months ended June 30, 2007, the Company reported net
income of $3.8 million, or $0.17 per diluted share, compared to a loss
of $3.3 million, or $(0.18) per share, for the comparable period in
2006. The results for the 2006 period included a charge for in-process
research and development associated with the acquisition of Bio-logic
Systems Corp. in January 2006. Excluding this charge, non-GAAP
earnings for the six months ended June 30, 2006 were $2.6 million, or
$0.13 per diluted share. The results for the first six months of 2007
reflect increases in net income and earnings per share of 48% and 31%,
respectively, compared to the non-GAAP results in 2006.

    Jim Hawkins, President and Chief Executive Officer of the Company
said, "I am pleased with our record results for the second quarter.
The quarter was led by strong growth in our worldwide hearing
screening business and the results of our most recent acquisition,
Olympic Medical.

    "As we previously reported, we increased spending for
infrastructure in the first quarter. In the second quarter of this
year, our general and administrative expenses have come down to more
normal levels. Our higher level of spending on R&D initiatives has
continued into the second quarter, most notably for our hearing and
EEG product lines, but we expect that our expenditures for these
projects should be winding down in the fourth quarter."

    "In transitioning production of the Olympic Cool-Cap from clinical
units to commercial units, we updated many of its components. Because
of its Class III device status, these component updates must receive
FDA pre-market approval. Consequently, in June we put a hold on
shipments of Cool-Cap units. While this delay impacted shipments, it
did not have an adverse impact on orders. We held up approximately
$500,000 of Cool-Cap shipments in the second quarter because of this
issue. We will resume shipments of the Cool-Cap upon FDA approval of
the new components, which we anticipate happening in the third
quarter," added Hawkins.

    "Even with this shipping delay, we still had an excellent quarter
with record results. Through our internal product development and
acquisitions we have developed market-leading positions for a number
of our products. We remain confident in our strategy as we continue to
position the company for growth in 2008 and beyond," said Hawkins.

    During 2006 the Company completed the acquisitions of Bio-logic
Systems, Deltamed, and Olympic Medical, in January, September, and
October, respectively. The acquisitions of Deltamed and Olympic
contributed to the reported revenue growth in the second quarter 2007.

    As of June 30, 2007 the Company had cash and cash equivalents of
$18.3 million, stockholders' equity of $107 million, working capital
of $39 million, and no long-term debt.

    2007 Guidance

    Natus increased its revenue guidance for the full year 2007. For
the full year 2007, the Company now expects revenue to range from
$118.3 million to $119.3 million. The Company had previously said
revenue would range from $117.5 million to $119.0 million. The Company
reiterated its earnings per share guidance, which it expects to range
from $0.49 to $0.52 per share.

    Natus also increased its previously announced revenue guidance for
the third quarter of 2007. For the third quarter of 2007, the Company
expects revenue to range from $30.0 million to $30.5 million. The
Company had previously said revenue would range from $29.5 million to
$30.0 million. The Company reiterated its earnings per share guidance,
which it expects to range from $0.13 to $0.14. This compares to
revenue of $21.8 million and earnings per share of $0.09 reported in
the third quarter of 2006.

    For the fourth quarter of 2007, the Company expects revenue to
range from $32.9 million to $33.4 million and earnings per share to
range from $0.19 to $0.21. This compares to revenue of $28.8 million
and earnings per share of $0.02 reported in the fourth quarter of
2006. The results for the 2006 period included a $3.9 million charge
for acquired in-process research and development associated with the
acquisition of Olympic Medical.

    The Company expects that it will utilize tax net operating loss
carryforwards to significantly reduce its taxable income in 2007, such
that it will pay taxes at a rate of only 12% to 15% for the year.

    The Company's 2007 guidance is on a GAAP basis, including the
impact of expensing employee equity-based compensation, which the
Company expects to be approximately $2.1 million for the full year
2007. The Company's guidance does not include the impact of any
one-time acquisition or restructuring related charges. All earnings
per share amounts are on a diluted basis.

    Use of Non-GAAP Financial Measures

    In addition to disclosing financial results calculated in
accordance with GAAP, this release contains non-GAAP financial
measures that exclude the effects of costs associated with the January
5, 2006 acquisition of Bio-logic Systems Corp. The Company believes
that the presentation of results excluding this acquisition-related
charge provides meaningful supplemental information to both management
and investors that is indicative of the Company's core operating
results. The Company also believes the in-process research and
development charge is not indicative of resources devoted to ongoing
research and development efforts. Therefore, the Company believes the
non-GAAP financial measures facilitate comparison of operating results
across reporting periods. A reconciliation between the Company's
results of operations on a GAAP and non-GAAP basis for the periods
reported is included as part of the condensed consolidated statements
of operations at the end of the Company's financial results release.

    The Company believes that both management and investors benefit
from referring to these non-GAAP financial measures in assessing the
Company's performance and when planning, forecasting, and analyzing
future periods. The non-GAAP financial measures also facilitate
management's internal comparisons to the Company's historical
performance. The non-GAAP financial measures disclosed by the Company
should not be considered a substitute for or superior to financial
measures calculated in accordance with GAAP, and the financial results
calculated in accordance with GAAP and reconciliations to those
financial statements should be carefully evaluated.

 impact on the tax provision.
