                AUTODESK REPORTS RECORD REVENUES OF $457 MILLION

    SAN RAFAEL, Calif., Nov. 16 /PRNewswire-FirstCall/ -- Autodesk, Inc.
(Nasdaq: ADSK) today reported record quarterly revenues of $457 million, an
increase of 21 percent over the third quarter of fiscal 2006.

    "Autodesk had a very solid quarter," said Carl Bass, Autodesk president and
CEO. "Customers around the world increasingly recognize the innovation and
productivity that Autodesk products provide. Customer adoption of Autodesk's
industry-leading 3D products is increasing and customer demand for our 2D
solutions remains very strong. Revenues from emerging economies increased to 15
percent of total revenue. Long term market trends favor Autodesk and we continue
to gain share as we execute our key strategies."

    Operational Highlights

    Autodesk's performance was driven by strong increases in revenues from 3D
products, products for the media and entertainment market and strong increases
in revenue from AutoCAD new seats and subscriptions. In addition, total revenues
from new seats, subscriptions and emerging economies showed strong growth.

    The company's 3D products, Inventor, Revit and Civil 3D, continue to
increase their market penetration. Combined revenues from these model-based
design products increased 36 percent over the third quarter of fiscal 2006 to a
record $98 million. 3D revenues reached 22 percent of total revenues in the
quarter. In total, Autodesk shipped more than 38,000 commercial seats of 3D in
the quarter including 18,200 seats of Revit, 13,000 seats of Inventor and 6,900
seats of Civil 3D.

    Revenues from the Media and Entertainment segment increased 50 percent over
the third quarter of fiscal 2006 to a record $64 million. Animation revenues
were $33 million in the quarter, an increase of nearly 160 percent over the
third quarter of fiscal 2006 and 14 percent sequentially. 3ds Max revenues
increased 28 percent compared to the third quarter of fiscal 2006. Revenues from
Autodesk Maya reached a record level, increasing 33 percent sequentially.
Advanced Systems revenues increased 5 percent both sequentially and compared to
the third quarter of fiscal 2006. Over 80 percent of Advanced Systems product
revenue in the quarter was Linux-based.

    Revenues from new seats increased by 20 percent compared to the third
quarter of last year. Revenues from new seats of Revit and Civil 3D increased 94
percent and 44 percent, respectively, compared to the third quarter of fiscal
2006. Revenues from new seats of AutoCAD increased by 24 percent compared to the
third quarter of last year. In addition, revenues from Buzzsaw increased 79
percent compared to the third quarter of last year. Revenues from new seats and
emerging businesses continue to represent approximately two-thirds of total
revenues.

    Subscription revenues increased 50 percent compared to the third quarter of
fiscal 2006 to $111 million or 24 percent of total revenues. Continued strength
in subscription attach rates and renewal rates drove a $12 million sequential
increase in deferred subscription revenues. Although upgrade revenues declined,
as expected, combined subscription and upgrade revenues increased 17 percent
compared to the third quarter of fiscal 2006 and continue to represent
approximately one-third of total revenues.

    Once again, emerging economies contributed robust growth in revenues.
Revenues from the emerging economies in Asia Pacific, Eastern Europe, Latin
America and the Middle East increased 38 percent over the third quarter of
fiscal 2006 and represented 15 percent of total revenues in the third quarter.

         *        Capital expenditures were $7 million.
         *        The company received $10 million from employee stock plans. As
                  a result of the voluntary review of the company's historical
                  stock option granting practices and the related accounting, no
                  shares were repurchased during the quarter.



         *        There were approximately 231 million total shares outstanding
                  and 242 million diluted shares outstanding in the third
                  quarter.
         *        Revenues in the Americas increased 21 percent over the third

                  Japan, revenues in Asia Pacific increased 36 percent compared
                  to last year.
         *        In the third quarter of fiscal 2007, spending for total costs
                  and expenses -- which include cost of license and other
                  revenue, cost of maintenance revenues, marketing and sales,
                  research and development, and general and administrative -
                  increased by $22 million sequentially, as expected. This
                  increase includes a $3 million write-down of Advanced Systems
                  inventory, $3.6 million in legal, tax and accounting fees
                  relating to the voluntary stock option review and a previously
                  disclosed $8.8 million one-time cash bonus to non-executive
                  employees enrolled in the company's Employee Stock Purchase
                  Plan. This bonus was approved by the Board to compensate for
                  the benefits lost by non-executive employees because Autodesk
                  did not issue shares through the Employee Stock Purchase Plan
                  due to the ongoing review.
         *        Interest and other income increased by $3 million sequentially
                  to $6 million.

    Business Outlook

    The following statements are forward-looking statements which are based on
current expectations and which involve risks and uncertainties some of which are
set forth below. As a result of the voluntary stock option review, the company
is not providing EPS guidance at this time.

    Fourth Quarter Fiscal 2007

    Net revenues for the fourth quarter of fiscal 2007 are expected to be
between $490 million and $500 million. Spending for total costs and expenses in
the fourth quarter is expected to be approximately flat with the third quarter.
Estimates of fourth quarter spending for total costs and expenses include
approximately $5M in legal, tax and accounting fees related to the voluntary
stock option review and do not take into account other charges, if any, likely
to result from the voluntary stock option review.

    Full Year Fiscal 2007

    For fiscal year 2007, net revenues are expected to be between $1.832 billion
and $1.842 billion.

    First Quarter Fiscal 2008

    Net revenues for the first quarter of fiscal 2008 are expected to be
approximately flat with the fourth quarter of fiscal 2007. Consistent with
normal seasonal trends, spending for total costs and expenses for the first
quarter of fiscal 2008 is projected to increase approximately $10 million
sequentially. First quarter fiscal 2008 estimates of spending exclude legal,
tax, and accounting fees, if any, or other charges, if any, likely to result
from the voluntary stock option review.

    Full Year Fiscal 2008

     For fiscal year 2008, net revenues are expected to be between $2.075
billion and $2.125 billion. Operating margins for the year are expected to
increase 3 to 4 percentage points, excluding expenses or other charges, if any,
resulting from the voluntary stock option review. Not taking into account SFAS
123R stock-based compensation expenses, amortization of acquisition related
intangibles of litigation accruals, legal, tax and accounting fees, if any, and
other charges, if any, resulting from the voluntary stock option review
operating margins for fiscal year 2008 are expected to increase 1 to 1.5
percentage points.

    Stock Option Review

    As previously disclosed the company is conducting a voluntary review of its
historical stock option granting practices and related accounting issues. The
company plans to become current in its periodic reports required under the
Exchange Act of 1934, as amended, following the completion of the independent
review.



    As previously disclosed, the Audit Committee has reached a preliminary
conclusion that the actual measurement dates for financial accounting purposes
of certain broad-based employee stock option grants issued in the past differ
from the recorded grant dates of such awards. As a result, the Audit Committee
believes the company will record additional non-cash stock-based compensation
expense related to stock option grants, but it is not yet able to determine the
amount of such charges or the resulting tax and accounting impact of these
actions or whether any historical periods would require restatement. Any
additional non-cash stock-based compensation expense recorded will not affect
the company's previously reported cash positions or revenues.

    The Audit Committee's review is ongoing and the conclusions discussed in
this press release are preliminary.

    Safe Harbor Statement

    This press release contains forward-looking statements that involve risks
and uncertainties, including statements in the paragraphs under "Business
Outlook" above, statements in the paragraphs under "Stock Option Review" above,
statements regarding anticipated market trends and other statements regarding
our expected performance. There can be no assurance that the outcome of the
voluntary stock option review will not result in a restatement of financial
results provided by the company for any historical or future period or other
adverse consequences. Factors relating to the voluntary stock option review
described above that could cause actual results to differ materially from this
forward looking statement made under "Stock Option Review" and elsewhere
include, but are not limited to: the final conclusions of the Audit Committee
and the Board of Directors (and the timing of such conclusions) concerning
matters relating to the company's stock option grants and the impact on the
amount and timing of previously awarded stock- based compensation and other
additional expenses to be recorded, accounting adjustments to the company's
financial statements for certain periods, and the company's ability to timely
file required reports with the SEC and meet the requirements of the NASDAQ
Global Select Market for continued listing of its shares. The stock option grant
practices under review and related matters could also lead to potential claims
and proceedings relating to such matters, including shareholder or employee
litigation and action by the SEC and/or other regulatory agencies, and negative
tax or other implications for the company resulting from any accounting
adjustments or other factors. Other factors that could cause actual results to
differ materially from the forward looking statements under "Business Outlook"
and elsewhere include the following: general market and business conditions,
expenses, resulting from the voluntary stock option review, our performance in
particular geographies, fluctuations in our tax rate, the timing and degree of
expected investments in growth opportunities, slowing momentum in maintenance or
subscription revenues, changes in the timing of product releases and
retirements, fluctuation in foreign currency exchange rates, difficulties
encountered in integrating new or acquired businesses and technologies, failure
to achieve sufficient sell-through in our channels for new or existing products,
failure of key new applications to achieve anticipated levels of customer
acceptance, pricing pressure, failure to achieve continued cost reductions and
productivity increases, failure to achieve continued migration from 2D products
to 3D products, failure to achieve continued success in technology advancements,
the financial and business condition of our reseller and distribution channels,
interruptions or terminations in the business of the company's consultants or
third party developers, failure to grow lifecycle management or collaboration
products, and unanticipated impact of accounting for technology acquisitions.

    Further information on potential factors that could affect the financial
results of Autodesk are included in the company's reports on Form 10-K for the
year ended January 31, 2006 and Form 10-Q for the quarter ended April 30, 2006
which are on file with the Securities and Exchange Commission. Autodesk does not
assume any obligation to update the forward-looking statements provided to
reflect events that occur or circumstances that exist after the date on which
they were made.

    (a) Information pending completion of stock option investigation.



     To supplement Autodesk's consolidated financial statements presented on a
     GAAP basis, we provide investors with certain non-GAAP measures, including
     non-GAAP total costs and expenses (such as non-GAAP cost of license and
     other revenues and total cost of revenues, non-GAAP sales and marketing
     expense, non-GAAP research and development expense, and non-GAAP general
     and administrative expense), non-GAAP income from operations, non-GAAP
     provision for income taxes, non-GAAP net income and non-GAAP diluted net
     income per share.

     For our internal budgeting and resource allocation process, Autodesk's
     management uses non-GAAP financial information that does not include: (a)
     the stock-based compensation impact of SFAS 123R, (b) certain large and
     non-recurring litigation expenses, (c) amortization of purchased
     intangibles and purchases of incomplete technology that result in an
     inprocess research and development expense, and (d) the net tax impact of
     the repatriation of certain foreign earnings. Autodesk's management uses
     these non-GAAP financial measures in making operating decisions because we
     believe the understanding of how we should invest in research and
     development and fund measures provide meaningful supplemental
     infrastructure and go-to-market strategies. In addition, these non-GAAP
     financial information regarding Autodesk's operational performance and
     gives us a better measures facilitate management's internal comparisons to
     our historical operating results and comparisons to competitors' operating
     results.

    As described above, Autodesk excludes the following items from one or more
of its non-GAAP measures:

    A. Stock compensation impact of SFAS 123R. These expenses consist of
       expenses for employee stock options and employee stock purchases under
       SFAS 123(R). Autodesk excludes stock-based compensation expenses from our
       non-GAAP measures primarily because they are non-cash expenses and
       management finds it useful to exclude certain non-cash charges to assess
       the appropriate level of various operating expenses to assist in
       budgeting, planning and forecasting future periods. Further, as Autodesk
       applies SFAS 123R, we believe that it is useful to investors to
       understand the impact of the application of SFAS 123R to our results of
       operations.



    B. Certain litigation expenses. These expenses relate to the Company's
       accrual of $16.8 million related to the $18 million jury award in the z4
       Technologies matter, where in the quarter ended April 30, 2006, Autodesk
       determined that (1) it is probable that a liability has been incurred and
       (2) the amount of loss could be reasonably estimated. Autodesk excludes
       this from its non-GAAP measures because it does not consider it to be
       reflective of ongoing operating results in the current period.

    C. Amortization of purchased intangibles and in-process research and
       development expenses. Autodesk incurs amortization of acquisition-related
       purchased intangible assets and charges related to in-process research
       and development, primarily in connection with its acquisition of certain
       businesses, such as Alias in January 2006. The amortization of purchased
       intangibles from a business combination is generally a non-cash expense
       and management finds it useful to exclude certain non-cash charges to
       assess the appropriate level of various operating expenses to assist in
       budgeting, planning and forecasting future periods.

    D. Tax impact of the repatriation of certain foreign earnings. In fiscal
       2006 and 2005, Autodesk repatriated foreign earnings under the American
       Jobs Creation Act of 2004. Future repatriations are not expected to
       reoccur. Autodesk excludes this item because the repatriation transaction
       is not reflective of ongoing operating results and has no direct
       correlation to the operation of Autodesk's business.

    Autodesk believes that where the adjustments used in calculating non-GAAP
net income and non-GAAP net income per share are based on specific, identified
amounts that impact different line items in the Condensed Consolidated
Statements of Income (including cost of license and other revenues and total
cost of revenues, gross margin, operating expenses, including sales and
marketing, research and development, and general and administrative expenses,
income from operations, provision for income taxes, net income, and diluted net
income per share) that it is useful to investors to understand how these
specific line items in the Condensed Consolidated Statements of Income are
affected by these adjustments for the following reasons:

    1. Cost of license and other revenues, total cost of revenues, and gross
       margin. Excluding stock-based compensation expense related to employee
       stock options and employee stock purchases from cost of license revenues
       and gross margin calculations assists investors in evaluating
       period-over-period changes without giving effect to these charges which
       are non-cash in nature. Excluding the impact from the amortization of
       purchased intangibles assists investors in evaluating period-over- period
       changes without giving effect to these charges which are a function of
       prior period acquisition transactions rather than the underlying
       operating activities of the period presented.

    2. Operating expenses (including sales and marketing, research and
       development, and general and administrative expenses). Excluding
       stock-based compensation expense related to employee stock options and
       employee stock purchases assists investors in evaluating period-over-
       period changes in each line item of operating expenses without giving
       effect to these charges which are non-cash in nature. Excluding the
       impact of (a) the amortization of purchased intangibles and inprocess
       research and development expenses and (b) certain litigation expenses
       assists investors in evaluating period-over-period changes to the
       affected line items in the Condensed Consolidated Statement of Income
       without giving effect to these charges which are a function of
       acquisition transactions or large and infrequent litigation costs rather
       than the underlying operating activities of the period presented.

    3. Income from operations. Excluding stock-based compensation expense
       related to employee stock options and employee stock purchases from the
       calculation of income from operations assists investors in evaluating
       period-over-period changes without giving effect to these charges which
       are non-cash in nature. Excluding the impact from (a) the amortization of
       purchased intangibles and in-process research and development expenses
       and (b) certain litigation expenses assists investors in evaluating
       period-over-period changes without giving effect to these charges which
       are a function of acquisition transactions or large and infrequent
       litigation costs rather than the underlying operating activities of the
       period presented.



    4. Provision for income taxes. Excluding the income tax effect of the
       non-GAAP pre-tax adjustments from the provision for income taxes assists
       investors in understanding the tax provision associated with those
       adjustments and the effective tax rate of Autodesk related to its ongoing
       operations in the period presented. Excluding the net tax impact of the
       repatriation of foreign earnings assists investors in comparing periods
       in which repatriation does not occur and in understanding the effective
       tax rate of Autodesk related to its ongoing operations in the period
       presented.

    5. Net Income, Net of Tax Effect of Non-GAAP Adjustments. Excluding
       stock-based compensation expense related to employee stock options and
       employee stock purchases from the calculation of net income assists
       investors in evaluating period-over-period changes without giving effect
       to these charges which are non-cash in nature. Excluding stock-based
       compensation expense related to employee stock options and employee stock
       purchases from the calculation of net income assists investors in
       evaluating period-over-period changes without giving effect to these
       charges which are non-cash in nature. Excluding the impact from (a) the
       amortization of purchased intangibles and in-process research and
       development expenses and (b) certain litigation expenses assists
       investors in evaluating period-over-period changes without giving effect
       to these charges which are a function of acquisition transactions or
       large and infrequent litigation costs rather than the underlying
       operating activities of the period presented. Excluding the income tax
       effect of the non-GAAP pre-tax adjustments from the provision for income
       taxes assists investors in understanding the tax provision associated
       with those adjustments and the effective tax rate of Autodesk related to
       its ongoing operations in the period presented. Excluding the net tax
       impact of the repatriation of foreign earnings assists investors in
       comparing periods in which repatriation does not occur and in
       understanding the effective tax rate of Autodesk related to its ongoing
       operations in the period presented.

    There are limitations in using non-GAAP financial measures because the
non-GAAP financial measures are not prepared in accordance with generally
accepted accounting principles and may be different from non-GAAP financial
measures used by other companies. In addition, the non-GAAP financial measures
are limited in value because they exclude certain items that may have a material
impact upon our reported financial results. Management compensates for these
limitations by analyzing current and future results on a GAAP basis as well as a
non-GAAP basis and also by providing GAAP total costs and expenses, GAAP
operating income, GAAP provision for income taxes, GAAP net income and GAAP
diluted net income per share in our earnings release. The presentation of
non-GAAP financial information is not meant to be considered in isolation or as
a substitute for the directly comparable financial measures prepared in
accordance with generally accepted accounting principles in the United States.
The non-GAAP financial measures are meant to supplement, and be viewed in
conjunction with, GAAP financial measures. Investors should review the
reconciliation of the non-GAAP financial measures to their most directly
comparable GAAP financial measures as provided in the tables accompanying our
press release.
