OPNET Announces Financial Results for First Quarter of Fiscal 2009

Revenue of $30.1 Million
Deferred Revenue of $31.4 Million
Diluted Earnings Per Share of $0.04
BETHESDA, Md., Aug. 5, 2008 (PRIME NEWSWIRE) -- OPNET Technologies, Inc.
(Nasdaq:OPNT), a leading provider of solutions for managing networks and
applications, today announced that quarterly revenue for the first fiscal
quarter, ended June 30, 2008, was $30.1 million, compared to $23.3 million for
the same quarter in the prior fiscal year. Diluted earnings per share for the
first quarter of fiscal 2009 were $0.04, compared to diluted earnings per share
of $0.03 for the same quarter in the prior fiscal year.

Marc A. Cohen, OPNET's Chairman and CEO, stated, "We are very pleased to have
achieved record quarterly revenue of $30.1 million during the quarter, which was
driven by a sequential increase in license revenue of $2.6 million. Our license
revenue of $12.9 million this quarter exceeded our previous license revenue
record of $11.2 million that we achieved in Q2 of fiscal 2007. Our license
revenue growth was driven by strong sales to corporate enterprises. We are also
very pleased to have improved our operating margin from negative 4.5% last
quarter to positive 3.1% this quarter. Our improved operating margin was the
result of our efforts to increase license revenue and control operating
expenses. While we are pleased with our fiscal Q1 results, we remain very
focused on efforts to improve our operating margin."

Cohen continued, "We believe that the demand for our software licenses is being
driven by our end-to-end application performance management solutions. With the
recent addition of ACE Live for real-time end user performance monitoring and
integrations with our ACE Analyst and Panorama products that provide
troubleshooting across distributed systems, networks, and client machines, we
are now delivering a comprehensive performance management suite. As a result,
OPNET customers can now plan, monitor, manage, and troubleshoot with much
greater ease, speed, and automation than they could before."

The Company's first quarter fiscal 2009 financial results are presented below.
The non-GAAP results exclude the income statement effects of stock-based
compensation and acquisition-related amortization of intangible assets. A
reconciliation of GAAP results to non-GAAP results has been provided in the
financial statement table following the text of the press release. For further
information, please refer to the section of the press release titled, "Use of
Non-GAAP Measures."

Use of Non-GAAP Measures

The Company uses non-GAAP operating income, non-GAAP operating profit margin,
non-GAAP net income and non-GAAP diluted earnings per share as supplemental
measures to GAAP to evaluate the Company's operational performance. These
financial measures exclude the impact of certain items and, therefore, have not
been calculated in accordance with GAAP. A detailed explanation of each of the
adjustments to such financial measures is described below. A reconciliation of
each of these non-GAAP financial measures to its most comparable GAAP financial
measure is also included below.

Management uses non-GAAP financial measures (a) to evaluate the Company's
historical and prospective financial performance as well as its performance
relative to its competitors, and (b) to measure operational profitability and
the accuracy of forecasting. In addition, many financial analysts who follow our
Company focus on and publish both historical results and future projections
based on non-GAAP financial measures. We believe that it is in the best interest
of our investors to provide this information to analysts so that they accurately
report the non-GAAP financial information. Moreover, investors have historically
requested these non-GAAP financial measures as a means of providing consistent
and comparable information with past reports of financial results.

While management believes that these non-GAAP financial measures provide useful
supplemental information to investors, there are limitations associated with the
use of these non-GAAP financial measures. These non-GAAP financial measures are
not prepared in accordance with GAAP, are not reported by all of the Company's
competitors and may not be directly comparable to similarly titled measures of
the Company's competitors due to potential differences in the exact method of
calculation. The Company compensates for these limitations by using these
non-GAAP financial measures only as supplements to GAAP financial measures and
by providing the reconciliations of the non-GAAP financial measures to their
most comparable GAAP financial measures.

The adjustments to these non-GAAP financial measures, and the basis for such
adjustments, are outlined below:

Amortization of intangibles and its related tax impact. The Company incurs
amortization of intangibles, which is included in its GAAP presentation of
amortization of acquired technology and customer relationships, and research and
development, related to various acquisitions it has made in recent years.
Management excludes these expenses and their related tax impact for the purpose
of calculating non-GAAP operating income, non-GAAP operating profit margin,
non-GAAP net income and non-GAAP diluted earnings per share when it evaluates
the continuing operational performance of the Company because these costs are
fixed at the time of an acquisition, and are then amortized over a period of
three to five years after the acquisition and generally cannot be changed or
influenced by management after the acquisition. Accordingly, management does not
consider these expenses for purposes of evaluating the performance of the
Company during the applicable time period after a given acquisition, and it
excludes such expenses when evaluating the Company's financial performance.

Stock-based compensation expense and its related tax impact. The Company incurs
expense related to stock-based compensation, which is included in its GAAP
presentation of cost of software license updates, technical support and
services, cost of professional services, research and development expense, sales
and marketing expense and general and administrative expense. Although
stock-based compensation is an expense of the Company and viewed as a form of
compensation, management excludes these expenses for the purpose of calculating
non-GAAP operating income, non-GAAP operating profit margin, non-GAAP net income
and non-GAAP diluted earnings per share when it evaluates the continuing
operational performance of the Company. Specifically, the Company excludes
stock-based compensation during its quarterly and annual assessments of the
Company's and management's performance. In evaluating the performance of senior
management, stock-based compensation is excluded from expenditure and
profitability results.
