         Moldflow Reports First Fiscal Quarter 2004 Results;
         Reports Significant Growth in Revenues and Earnings


    WAYLAND, Mass.--(BUSINESS WIRE)--Oct. 23, 2003--Moldflow
Corporation (NASDAQ: MFLO) today announced the results for its first
fiscal quarter of 2004. Worldwide revenues of $9.5 million for the
quarter ended September 27, 2003 represented a 15% increase from the
corresponding quarter of fiscal 2003. For the first fiscal quarter of
2004, Moldflow reported net income, as measured under generally
accepted accounting principles ("GAAP"), of $417,000, or $0.04 per
diluted share, compared to net income of $15,000, or $0.00 per share,
during the same quarter of fiscal 2003.
    Roland Thomas, Moldflow's president and CEO said, "We are pleased
to report results for the first fiscal quarter of 2004 that are in
line with our expectations for the quarter and which reflect the
improving long-term business conditions in many of our markets and the
trends we have noted over the last several quarters. Our operating
results are particularly gratifying as they reflect continued growth
in product revenues on a year-over-year basis, both in absolute terms
and on a constant currency basis. In addition, we achieved meaningful
growth in earnings."
    He continued, "As we entered this fiscal year, we set out a plan
to manage the company for growth with increased profitability and cash
flows, while continuing our investments in research and development
and in the distribution channels appropriate to reach our global
customer base. We met the milestones necessary to deliver on those
objectives during the first quarter, achieving both earnings growth
and positive cash flow from operations. To address the opportunities
available to us to expand our revenue base through alternate
distribution channels, we appointed a director of strategic alliances
who comes to us with significant experience in the design and
engineering software industry."
    Thomas noted, "Our research and development activities resulted in
the introduction of Moldflow Manufacturing Solutions(TM) (MMS(TM)) 1.1
in September 2003. This release contains innovative product features
created in direct response to the needs of our customers, and
demonstrates our ability to rapidly tailor our product development
plans to the market's evolving requirements. At the end of the second
quarter, we plan to release the English-language version of our
plant-wide production monitoring product. This product suite, acquired
last year, has shown meaningful sales volume in its initial
French-language release. The release of this product in English will
complement our existing MMS capabilities and will allow us to bring a
full suite of production and process monitoring solutions to our
global customer base. Also, by quarter-end, we plan to ship the next
major release of Moldflow Plastics Advisers(R) (MPA(R)), containing
significant new capabilities targeted at engineers who use our Design
Optimization products during the initial stages of part and mold
design. By expanding the breadth of analysis capabilities in MPA, we
seek to deliver enhanced cost-effective simulation capabilities to a
wider mid-market audience."
    He concluded, "The results for the first quarter provide a solid
foundation for achievement of our plans for the fiscal year. We will
continue to execute on our strategy to be the leading global provider
of plastics focused automation and optimization solutions to the
global manufacturing industry."

    First quarter 2004 revenues totaled $9.5 million and represented

    As of September 27, 2003, the Company had $52.7 million in cash
and marketable securities and no long-term debt. Cash flow from
operations in the first fiscal quarter of 2004 was $287,000 and free
cash flow was approximately breakeven. Please refer to the Unaudited
Condensed Consolidated Statement of Cash Flows attached to this press
release for a complete reconciliation of free cash flow to cash flows
provided by operating activities as measured under GAAP.
    The Company had a total of 246 employees at September 27, 2003, of
which 36 were sales representatives, 74 were in research and
development, and the remainder were employed in sales management,

    Business Outlook

    The current business outlook is based on information as of October
23, 2003 and is current as of that day only. Moldflow expects revenues
for the second fiscal quarter of 2004 to be between $9.8 million and
$10.3 million and net income per diluted share, measured under GAAP,
to be between $0.01 and $0.03 per share, assuming an effective income
tax rate of 37%.
    Moldflow expects free cash flow for the second fiscal quarter of
2004 to be between breakeven and negative $600,000. Free cash flow in
Moldflow's outlook is based upon a projection of cash flow from
operations of between $400,000 and negative $200,000, which includes
the effect of required foreign tax payments, reduced by capital
expenditures, including capitalized software development costs,
projected to be approximately $400,000.

    Financial Results

    The unaudited condensed consolidated financial statements and
supplemental information for the first fiscal quarter ended September
27, 2003 follow.

    Use of Non-GAAP Financial Information

    To supplement our unaudited consolidated financial statements
presented on a GAAP basis, we may use a non-GAAP, or "pro forma",
measure referred to as free cash flow that we believe is appropriate
to enhance an overall understanding of our historical financial
performance and future prospects. Free cash flow is among the primary
indicators management uses as a basis for evaluating our financial
performance as well as for forecasting of future periods. For this
reason, and because this measure presents additional information that
is not readily ascertainable from the GAAP presentation, management
believes this non-GAAP measure can be useful to investors, potential
investors and others. The presentation of free cash flow is not meant
to be considered in isolation or as a substitute for cash flow from
operations prepared in accordance with GAAP.

    Information Dissemination

    Moldflow will host a conference call to discuss the first quarter
2004 results and future outlook at 11:30 a.m. US Eastern time today. A
live Webcast of the conference call, together with this press release
and supplemental financial information, can be accessed through the
Company's Website at www.moldflow.com in the Investor Information
section. In addition, the call, press release and supplemental
information will be archived and can be accessed through the same
