   CompuDyne Reports GAAP Earnings Per Share of $0.10 for 2006 First Quarter
    - Adjusted Earnings Per Share, Excluding Stock Option Expense, Was $0.13
                      - Company's Recovery is Taking Hold

    ANNAPOLIS, Md.--(BUSINESS WIRE)--April 27, 2006--CompuDyne
Corporation (Nasdaq:CDCY), an industry leader in sophisticated
security products, integration and technology for the public security
markets, today reported net income of $0.10 per share for the first
quarter of 2006, compared to a loss of $0.04 per share reported in the
first quarter of 2005. Revenues in the first quarter of 2006 were
$40.5 million, up from $36.3 million in the first quarter of 2005.
Expenses in the first quarter of 2006 included $255 thousand in
non-cash stock option expense. Earnings per share before this non-cash
charge was $0.13.
    Institutional Security Systems revenue was $13.4 million in the
first quarter of 2006 compared to $15.7 million in the first quarter
of 2005. Pre-tax income declined from $1.2 million in the 2005 first
quarter to $0.1 million in the 2006 first quarter. First quarter 2006
revenues and earnings were negatively impacted by delays in the start
of some projects. Legal costs remained high at $138 thousand for the
quarter as we continue to pursue recoveries on prior year contract
losses.
    Attack Protection revenue was $11.7 million in the first quarter
of 2006, up 69.4% compared to $6.9 million in the first quarter of
2005. Pre-tax income improved from $499 thousand in the 2005 first
quarter to a pre-tax income of $1.2 million in the 2006 first quarter.
The Norshield brand business, which supplies bullet, blast and attack
resistant windows and doors as well as vehicle barrier systems,
benefited from sharply increased backlogs as well as from significant
progress made during 2005 in reducing costs and improving quality. The
Fiber SenSys ("FSI") brand business, which is one of the world's
largest supplier of fiber optic based perimeter alarm systems,
continued to be negatively impacted by delays in military tests of
important new products. This process is now substantially behind us
and FSI is expected to have much improved results during the balance
of the year.
    Public Safety & Justice ("PS&J") revenues increased to $11.8
million in the first quarter of 2006 compared to $11.7 million in the
first quarter of 2005. Pre-tax results for PS&J in the first quarter
of 2006 were breakeven compared to a loss of $482 thousand in the
first quarter of 2005. While PS&J started the year with improved
backlogs, they are still not at levels necessary for adequate
profitability, although the pipeline of prospective new business is
sharply higher. In addition, the decision was made in 2005 to
significantly accelerate the research and development effort to
migrate to a full Service Oriented Architecture and .NET based product
suite, a commitment which is expected to negatively impact PS&J income
in 2006 by $2.5 million but which will materially improve future
revenues and margins. The late 2005 acquisition of Xanalys, with one
of the country's foremost suites of investigative and case management
software, is being introduced to PS&J's client base, and had an
important sale to the Australian Department of Defense in the first
quarter of 2006. During the first quarter of 2006 PS&J moved its
headquarters to Pleasanton, California, a move that should both
increase the efficiency and effectiveness of its headquarters
operations.
    Integrated Electronic Systems revenue was $3.6 million in the
first quarter of 2006 compared to $2.0 million in the first quarter of
2005 and resulted in pre-tax income of $184 thousand for the first
quarter of 2006 compared to breakeven results for the first quarter of
2005. The re-bid of the Bureau of Engraving & Printing contract,
occasioned by a protest filed by the previous incumbent, remains
unresolved.
    For the first quarter of 2006, our corporate pre-tax loss totaled
$0.9 million. Full year audit and costs related to compliance with
Section 404 of Sarbanes-Oxley are expected to be far below 2005
levels.
    While backlogs declined during the first quarter of 2006, by $19.7
million to $128.5 million, quoting and bidding activity levels
continue much higher than in recent years.
    While the Company does not provide estimates of future results, we
do expect the second quarter of 2006 to generate positive results.

    Certain statements made in this press release constitute
"forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995, including those statements
concerning the Company's expectations with respect to future operating
results and other events. Although the Company believes it has a
reasonable basis for these forward-looking statements, these
statements involve risks and uncertainties that cannot be predicted or
quantified and consequently, actual results may differ materially from
those expressed or implied by such forward-looking statements. Factors
which could cause actual results to differ from expectations include,
among others, capital spending patterns of the security market and the
demand for the Company's products, competitive factors and pricing
pressures, changes in legislation, regulatory requirements, government
budget problems, the Company's ability to secure new contracts, the
ability to remain in compliance with its bank covenants, delays in
government procurement processes, inability to obtain bid, payment and
performance bonds on various of the Company's projects, technological
change or difficulties, the ability to refinance debt when it becomes
due, product development risks, commercialization difficulties,
adverse results in litigation, the level of product returns, the
amount of remedial work needed to be performed, costs of compliance
with Sarbanes-Oxley requirements and the impact of the failure to
comply with such requirements, risks associated with internal control
weaknesses identified in complying with Section 404 of Sarbanes-Oxley,
the Company's ability to realize anticipated cost savings, the
Company's ability to simplify its structure and modify its strategic
objectives, and general economic conditions. Risks inherent in the
Company's business and with respect to future uncertainties are

    This press release contains unaudited financial information that
is not prepared in accordance with generally accepted accounting
principals (GAAP). Investors are cautioned that the non-GAAP financial
measures are not to be construed as an alternative to GAAP. The
Company's management uses earnings before interest, taxes,
depreciation and amortization, as adjusted for non-cash stock option
expense (EBITDAS), in its internal analysis of results of operations
and monitors EBITDAS to evaluate the Company's compliance with certain
of its bank covenants. Management believes that EBITDAS is useful to
investors as a meaningful comparison between periods and as an
analysis of the critical components of the Company's results of
operations. Management also believes that EBITDAS is useful to
investors because it allows them to evaluate the Company's compliance
with certain of its bank covenants.
