                  PTC Reports Fiscal 2003 Third Quarter Results


NEEDHAM, Mass., July 16, 2003 - PTC (Nasdaq: PMTC), the product development
company(TM), today reported revenue totaling $165.2 million for the third
quarter ended June 28, 2003, compared with $178.1 million for the same period
last year. Net loss for the third quarter was $33.8 million, or $0.13 per share,
compared to net loss of $27.3 million, or $0.10 per share, for the year-ago
period. During the third quarter of 2003, PTC recorded restructuring and other
charges of $15.1 million, compared to restructuring and other charges of $18.4
million in the year-ago period. Cash and investments were $208 million at the
end of the third quarter.

Total design solutions revenue for the third quarter was $123.6 million, which
was down 4% sequentially. Design solutions license revenue was $38.0 million,
down 5% sequentially. However, the Pro/ENGINEER component of this license
revenue improved sequentially and year over year, driven by Pro/ENGINEER
Wildfire.

Total Windchill revenue in the third quarter was $41.6 million, down 2%
sequentially. Windchill license revenue was $10.6 million, compared with $15.2
million in the second quarter. This is primarily attributable to diminished
transaction size in the quarter, as the number of transactions remained stable
sequentially. Additionally, PTC sold Windchill software to a record 97 new
customers this quarter, bringing the total Windchill customer count to 1,005.
Windchill Link solutions license revenue represented 54% of overall Windchill
license revenue.

"Although we continue to face revenue challenges, customer adoption of our new
product offerings confirms that our unique approach to product lifecycle
management drives value for our customers," said C. Richard Harrison, president
and chief executive officer of PTC. "We are focused on helping manufacturing
companies improve their competitive positions by putting product development at
the heart of their businesses. Our broad and well-architected product offering,
together with our service expertise, is well-suited to this important process.

"Customers are validating the benefits of using a fully integrated product
development system," continued Harrison. "This is evidenced by the significant
growth in sales of our Flex 3C package that combines PTC's solutions for digital
product creation, collaboration and control. These customers include: Asahi
Matsushita Electric, Concurrent Technologies Corporation, Harman Becker
Automotive Systems, Harris Corporation, Hewlett Packard Company, Maxtor, Reed
Tool Company, Smith International and Xerox Corporation."

"During the quarter, we began the implementation of the cost reduction plan
announced in April," said Neil Moses, PTC's new executive vice president and
chief financial officer. "The objective of this plan is to lower PTC's quarterly
operating cost structure from $180 million to $160 million entering fiscal 2004.
In addition, we have recently committed to reducing our quarterly operating cost
structure further, to $150 million by the end of fiscal 2004. Our goal is to be
profitable in 2004, while maintaining our dedication to product quality and
customer satisfaction."

Moses concluded, "For the fourth quarter of 2003, we expect revenue to be in the
range of $160 million to $170 million and net loss per share to be in the range
of $0.10 to $0.14. This guidance includes a restructuring charge of
approximately $15 million for the quarter related to the cost reduction
initiatives outlined above."
