</DIV>


<DIV align="center" style="font-size: 10pt; margin-top: 18pt"><B>- Company Delivers Year-Over-Year Revenue Growth of 9% and Non-GAAP Operating Income Growth of
34% -</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>NEEDHAM, Mass., January&nbsp;23, 2008 </B>&#151; PTC (Nasdaq: PMTC), the Product Development Company<SUP style="font-size: 85%; vertical-align: text-top">&#174;</SUP>, today
reported GAAP revenue of $241.2&nbsp;million for the first quarter ended December&nbsp;29, 2007, up 9% from
the same period last year. Non-GAAP revenue for the first quarter was $242.5&nbsp;million. Non-GAAP
revenue excludes the effect of purchase accounting on the fair value of the acquired deferred
maintenance revenue balance of CoCreate Software GmbH, which PTC acquired during the first quarter.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&#147;We performed well in the first quarter,&#148; said C. Richard Harrison, president and chief executive
officer. &#147;Our focus on delivering significant operating margin improvement in 2008 has begun to
pay off. We delivered an 18.2% non-GAAP operating margin in the first quarter, a 330 basis point
improvement from the same period last year. Our continued efforts to evolve our distribution and
services models, our globalization strategy, and the immediate non-GAAP operating margin accretion
provided by CoCreate contributed to this improvement. In addition, we continue to deliver revenue
growth that is higher than market growth rates.&#148;
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">GAAP operating income for the first quarter of 2008 was $14.9&nbsp;million, or 6.2% of total GAAP
revenue, compared with $21.0&nbsp;million, or 9.5% of total GAAP revenue in the year-ago period. GAAP
net income for the first quarter of 2008 was $9.9&nbsp;million, or $0.08 per diluted share, compared
with GAAP net income of $15.2&nbsp;million, or $0.13 per diluted share, in the year-ago period.
Non-GAAP operating income, which excludes the effect of purchase accounting on the acquired
deferred maintenance revenue balance of CoCreate, stock-based compensation cost, restructuring
charges, amortization of acquisition-related intangible assets, and in-process research and
development write-offs associated with acquisitions, was $44.1&nbsp;million for the first quarter of
2008, or 18.2% of total non-GAAP revenue, compared with $33.0&nbsp;million, or 14.9% of total GAAP
revenue, in the year-ago period. Non-GAAP net income, which excludes the items excluded from
non-GAAP operating income and the related tax effect of those items, was $31.1&nbsp;million for the
first quarter of 2008, or $0.26 per diluted share, compared to $26.8&nbsp;million in the year-ago
period, or $0.23 per diluted share. We have provided a reconciliation between GAAP and non-GAAP
results in the attached financial tables.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">PTC&#146;s GAAP and non-GAAP results for the first quarter of fiscal 2008 include expenses of $3.2
million associated with its restatement of the third quarter of 2007 and prior financial results
announced and completed during the quarter. As previously reported, PTC reversed its valuation
allowance against deferred tax assets in the U.S. and a foreign jurisdiction in the third quarter
of 2007. Therefore, the GAAP and non-GAAP effective income tax rates of 40% and 32%, respectively,
in the first quarter of 2008 are higher than the GAAP and non-GAAP effective income tax rates of
30% and 21%, respectively, in the first quarter of 2007. We have provided more information about
the impact of this change in the attached financial tables.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cash and cash equivalents were $215&nbsp;million at the end of the first quarter of 2008, ahead of
expectations. PTC used $50&nbsp;million of cash during the quarter to help finance the acquisition of
CoCreate and also repaid $15&nbsp;million of the $220&nbsp;million borrowed under its revolving credit
facility to finance the rest of

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">PTC has changed its assumptions for our future GAAP and non-GAAP tax rates. Previously, our 2008
guidance reflected an assumption that our GAAP and non-GAAP effective income tax rates would be
approximately 40%. The current guidance reflects an assumption that our GAAP and non-GAAP
effective income tax rates will be 37.5%. Additionally, upon the close of the CoCreate
acquisition, our estimate was that the acquired deferred maintenance revenue fair-value write-down
related to that transaction would impact our GAAP revenue by about $10&nbsp;million in Fiscal 2008.
Upon completion of our preliminary purchase accounting for the transaction, our current expectation
is that it will impact our GAAP revenue by about $5&nbsp;million in Fiscal 2008. This is reflected in
the guidance above.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><U><B>Important Information about Non-GAAP References</B></U>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">To supplement our financial results presented on a GAAP basis, we use non-GAAP measures, which
exclude certain business combination accounting entries and expenses related to acquisitions as
well as other expenses including stock-based compensation and restructuring charges, that we
believe are helpful in understanding our financial results and our projected future financial
performance. PTC believes these non-GAAP measures aid investors&#146; overall understanding of PTC&#146;s
results by providing a higher degree of transparency for certain financial measures and providing a
level of disclosure that helps investors understand how PTC plans and measures its own business.
We believe that providing non-GAAP measures affords investors a view of our operating results that
may be more easily compared to peer companies and enables investors to consider PTC&#146;s operating
results on both a GAAP and non-GAAP basis in periods when PTC is engaged in acquisition activities
or undertaking restructuring activities. However, non-GAAP revenue, non-GAAP operating income,
non-GAAP net income and non-GAAP earnings per share should be construed neither as an alternative
to GAAP revenue, GAAP operating income, GAAP net income or GAAP earnings per share as an indicator
of our operating performance nor as a substitute for cash flow from operations as a measure of
liquidity because the items excluded from the non-GAAP measures often have a material impact on
PTC&#146;s results of operations. Therefore, management uses, and investors should use, non-GAAP
measures in conjunction with our reported GAAP results.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our management regularly uses our supplemental non-GAAP financial measures internally to
understand, manage and evaluate our business and to make operating decisions. These non-GAAP
measures are among the primary factors management uses in planning for and forecasting future
periods. In addition, compensation of our executives is based in part on the performance of our
business based on these non-GAAP measures. Our non-GAAP financial measures reflect adjustments
based on the following items, as well as the related income tax effects:

    <TD>Deferred maintenance support revenue: Business combination accounting rules require us
to account for the fair value of support contracts assumed in connection with our
acquisitions. Because these are typically one-year contracts, our GAAP revenues for the
one-year period subsequent to our acquisitions do not reflect the full amount of software
license updates and product support revenues on assumed support contracts that would have
otherwise been recorded by the acquired entities. The non-GAAP adjustment, reflected in
non-GAAP revenue, is intended to reflect the full amount of such revenues. We believe this
adjustment is useful to investors as a measure of the performance of the acquired business
in the current fiscal year and provides a basis for comparing maintenance revenue in
subsequent fiscal years which are not impacted by the GAAP purchase accounting adjustment.</TD>
