Key Highlights of Operating Measures YoY YTD In millions Q3’18 YoY Q3 YTD YTD Management Comments CC CC • Q3’18 bookings of $113M were near the high end of our guidance range of $105M to $115M, including a $2M Fx headwind, representing 26% YoY growth (23% in constant currency). • YTD bookings grew 15% overall, 11% in constant currency, and 13% in constant currency when adjusting for the early close of the $7M mega-deal at the end of Q4’17. • Through Q3 YTD, CAD bookings grew double-digits, continuing to outpace market growth rates, and PLM bookings have tracked above market growth rates after gaining renewed momentum in Q3. SLM posted solid bookings results for the second quarter in a row, further evidence that our new organizational focus is delivering encouraging results. • IoT delivered a very strong quarter with growth well License and above the market growth rate. Customer Subscription $113 26% 23% $316 15% 11% expansions accounted for over 50% of our Bookings ThingWorx bookings, and the number of six-figure deals grew over 80% YoY, driven by these expansions. IoT bookings growth through the first three quarters of FY’18 is above the 30-40% estimated IoT market growth rate, when excluding the 8-figure mega deal from Q1’17. • Our global channel continues to exceed expectations, growing bookings double-digits for the tenth consecutive quarter. • Geographically, the Americas had a solid quarter, growing 9%; as expected, Europe rebounded in Q3 with 16% YoY growth; and APAC had a very strong third quarter, against a relatively easy comparison. Japan grew sequentially again, following a solid Q2’18, and is tracking at or above its plan for the year. We believe we have put the FY’17 challenges there behind us. Subscription • Q3’18 new subscription ACV grew 54% YoY and $44 54% 50% $117 28% 23% ACV 28% YTD. • A higher-than-forecasted proportion of new bookings from APAC, where we currently still sell perpetual software, resulted in upside to our perpetual license guidance. This resulted in subscription mix of 78%, which was a 1,400 bps increase over Q3’17. Subscription • Americas and EMEA, where we no longer sell % of 78% 74% perpetual licenses, except for Kepware, are at Bookings approximately our target 85% subscription mix, even though most of Kepware is sold in the Americas and EMEA. • We announced today that globally, beginning January 1, 2019, we will only sell subscription, except for Kepware.

Key Highlights of Quarterly Financial Measures In millions, YoY except per Q3’18 YoY Management Comments CC share amounts • Software revenue grew double-digits for the fourth consecutive quarter and Software was up 10% YoY, despite a 1,400 basis point increase in subscription mix YoY. Revenue: $274 10% 7% • Subscription revenue grew 69% YoY and recurring software revenue grew 15% GAAP YoY, and has grown double-digits for six consecutive quarters. $274 10% 7% • Approximately 91% of Q3 software revenue was recurring, up from 87% in the Non-GAAP year-ago period. • Total revenue was at the high-end of our guidance range of $310M to $315M Total Revenue: and grew 8%, including 10% software revenue growth, partially offset by a 6% GAAP $315 8% 5% decline in Professional Services. • As compared to our guidance, Fx headwinds of just over $3M, and $4M less Non-GAAP $315 8% 5% professional services revenue than expected, was offset by the higher perpetual software license revenue. EPS: • Both GAAP and non-GAAP EPS results exceeded the high end of our GAAP $0.14 NM NM guidance ranges for the quarter. • GAAP EPS improved by $0.15 YoY and non-GAAP EPS improved by $0.08 YoY, Non-GAAP $0.36 29% 13% due to a combination of revenue growth and continued expense discipline. Software Revenue Performance by Group All references are to GAAP revenue, unless otherwise noted YoY In millions Q3’18 YoY Management Comments CC • Solutions software revenue growth is due to the strong CAD, PLM and global channel bookings performance over the past several years, despite a 1,300 Solutions basis point increase in subscription mix in Q3’18 compared to Q3’17. Software $242 9% 5% • Solutions recurring software revenue grew 13% YoY and has grown double- Revenue digits for six consecutive quarters. As our transition matures, recurring software revenue growth is expected to accelerate due to the compounding benefit of a subscription business model. • IoT software revenue grew 26% year-over-year and 10% sequentially to a record level, driven by 33% growth in recurring IoT software revenue, despite a 1,700 basis point increase in subscription mix from Q3’17. In general, IoT IoT Software $32 26% 24% recurring software revenue growth is due to the strong IoT bookings over the Revenue past several years. As our transition matures, recurring software revenue growth is expected to accelerate due to the compounding benefit of a subscription business model. Page 3 of 14

Software Revenue Performance by Region All references are to GAAP revenue, unless otherwise noted YoY In millions Q3’18 YoY Management Comments CC Americas • Strong bookings performance has been driving revenue growth in the Software $118 9% 9% Americas, despite a 500 basis point increase in the subscription mix. Revenue Europe Software • Europe revenue growth of 11% YoY is the result of seven double-digit bookings Revenue $101 11% 3% growth quarters between Q4’16 and Q3’18, offset by a 2,400 basis point increase in the subscription mix in Q3’18 compared to Q3’17. • Double-digit revenue growth in APAC is due to the recent improvement in bookings performance. APAC Software $55 12% 9% • Japan made continued progress on its recovery, and appears to be tracking Revenue at or above its full year plan. We believe we have put our FY’17 challenges there behind us. Operating Performance In millions Q3’18 Management Comments Operating Expense: • GAAP operating expense was $1M above guidance due to certain transactional costs $212 GAAP in the quarter. • Non-GAAP operating expense was within our guidance range due to continued $186 Non-GAAP expense discipline and aided by Fx. Operating Margin: • Both GAAP and non-GAAP operating margin were at the high-end or above our GAAP 7% guidance ranges due to perpetual license revenue results above expectations and costs in line with our guidance. Non-GAAP 18% Tax Rate: -70% • Our GAAP tax rate benefitted from additional guidance on the state tax implications GAAP of the Tax Cuts and Jobs Act. 6% • Our non-GAAP tax rate was below guidance due to the mix of geographic profits. Non-GAAP Page 4 of 14

Other Highlights in Quarterly and Annual Operating Performance • For Q3’18, annualized recurring revenue (ARR) was approximately $994 million, which grew 15% or $129 million year over year and grew 3% or $33 million sequentially, despite Fx headwinds. ARR has now grown double-digits year over year for six consecutive quarters. • Total Deferred Revenue consists of Billed Deferred Revenue and Unbilled Deferred Revenue. In Q3’18, Total Deferred Revenue grew 33% year-over-year and declined 4% sequentially. Total Deferred Revenue fluctuates quarterly based upon the contractual billings dates in our recurring revenue contracts. Currency movements during Q3’18 reduced Total Deferred Revenue by about $35 million sequentially, reducing QoQ growth by approximately 300 basis points. Q3’18 Q2’18 Q3’17 Q/Q Y/Y (in millions) 6/30/18 3/31/18 7/1/17 % Change % Change Billed Deferred Revenue $484 $498 $465 -3% 4% Unbilled Deferred Revenue $726 $765 $443 -5% 64% Total Deferred Revenue $1,210 $1,263 $909 -4% 33% • Billed Deferred Revenue grew 4% year-over-year and declined 3% sequentially. Billed Deferred Revenue primarily relates to software agreements invoiced to customers for which the revenue has not yet been recognized. Billed Deferred Revenue fluctuates quarterly based upon the contractual billings dates in our recurring revenue contracts, the timing of our fiscal reporting periods, and Fx. Q3’18 ended on June 30th this year vs. July 1st last year. Recurring billings on July 1, 2018 were about $39 million, so on an apples-to-apples basis, billed deferred would have increased 12%. • Unbilled Deferred Revenue grew 64% year-over-year and declined 5% sequentially; the sequential declines were due to quarterly fluctuations in contractual billing dates and Fx headwinds. Unbilled Deferred Revenue is contractually committed orders for license, subscription and support with a customer for which the customer has not been invoiced and the associated revenue has not been recognized. We generally do not invoice prior to the contractual subscription start or anniversary date. We do not record Unbilled Deferred Revenue on our Consolidated Balance Sheet until we invoice the customer. Note that the increase in unbilled deferred revenue is not due to a longer average contract duration, which remained at approximately 2 years for new subscription contracts. • For Q3’18, approximately 91% of GAAP and non-GAAP software revenue came from recurring revenue streams. • For Q3’18, cash flow provided by operating activities was $49 million, and free cash flow was $42 million, both of which include cash payments of approximately $1 million related to our past restructuring plans. Year-to-date cash flow provided by operating activities was $185 million and free cash flow was $167 million, both of which include cash payments of approximately $2 million related to our past restructuring plans. • Cash, cash equivalents, and marketable securities totaled $321 million as of June 30, 2018. • As of June 30, 2018, gross borrowings totaled $698 million, including $500 million of senior notes and $198 million outstanding under our revolving credit facility. Under our revolving credit facility, our leverage covenant is limited to 4.5 times adjusted EBITDA. Further, if our leverage ratio exceeds 3.25 times adjusted EBITDA, our stock repurchases are limited to $50 million in a year. Our leverage ratio at the end of Q3’18 was 2.46. As of June 30, 2018, we had approximately $384 million available to borrow under the credit facility. Page 5 of 14

• Continuing the phased global rollout of our subscription licensing model, we announced in January 2018 that new software licenses for our core solutions and ThingWorx industrial innovation platform would be available globally only by subscription, effective January 1, 2018, with a few geographic exceptions – namely, China, Korea, Taiwan, Russia, Turkey and India. Today we announced that as of January 1, 2019, these six countries will too offer only subscription software licenses for our core solutions and ThingWorx industrial innovation platform. Kepware will continue to be available under perpetual licensing. Customers globally will be able to continue to use their existing perpetual licenses and renew support on active licenses. Net Reporting of Deferred Revenue Changes PTC has historically reported the impact of deferred revenue changes on cash flow from operations using a “net” method. Under this “net” method, the change in deferred revenue is presented net of the change in uncollected receivables related to such deferred revenues. Particularly in quarters where we have significant billings at or near the end of a quarter (like January 1 or April 1), this presentation provides a more accurate reflection of the cash flows in the period. Under the “gross” method (illustrated on the right-side of the table below), the total change in deferred revenue on the balance sheet is presented ($14 million, less a $14 million impact related to changes in foreign currency exchange rates), and the change in the related accounts receivable of approximately $24 million is included in other current assets and reported in “Other” below. In the “net” method, as reported by PTC, the net change of $24 million is included in deferred revenue. Cash flow from operating activities is the same in both cases. As Reported (Net) Pro Forma (Gross) (in millions) Q3’18 Q3’18 Cash flows from operating activities: 6/30/18 6/30/18 Net income $17 $17 Stock-based comp and D&A 39 39 Accounts receivable (11) (11) Deferred revenue 24 0 Other (20) 4 Net cash provided by operating activities $49 $49 Page 6 of 14

Q4’18 and FY’18 Guidance Our Q4’18 and FY’18 guidance includes the following general considerations: • Global macroeconomic conditions appear to have mostly stabilized and no longer appear to be a headwind to our performance, particularly in the industrial sector, creating an improving backdrop in the more mature CAD and PLM markets, which tend to be more cyclical. These economic conditions have been factored into our guidance. • Our Fx assumptions in our guidance approximate current rates. • Our Q4’18 share count guidance has increased by 2 million shares, to reflect the pending equity investment in PTC by Rockwell Automation. Rockwell Automation has agreed to make a $1 billion equity investment in PTC, by acquiring 10,582,010 shares at a price of $94.50. We expect the transaction to close on or around July 19, 2018. PTC plans to use these funds to execute an accelerated share repurchase (ASR) agreement on or around July 20, 2018. During the contract period of the ASR, a period of approximately 10 months, we expect outstanding shares to increase by approximately 2 million, which will be modestly dilutive to GAAP and non-GAAP EPS.

In 2019, we will be moving into a new worldwide headquarters in the Boston Seaport District and we will be vacating our current headquarters space. Because our current headquarters lease will not expire until November 2022, we are seeking to sublease that space. If we are unable to sublease our current headquarters space for an amount at least equal to our rent obligations under the current headquarters lease, we will bear overlapping rent obligations for those premises and will be required to record a charge related to any rent shortfall. A charge for such shortfall will be recorded in the earlier of the period that we cease using the space (which will likely occur in the second quarter of our fiscal 2019), or the period we exit the lease contract. Additionally, we will incur other costs associated with the move which will be recorded as incurred.

Long-Range Targets (Non-GAAP) Our long-range, non-GAAP targets for fiscal 2023 are below. Please note that these targets are included in a long-term operating model presentation posted on our investor relations website at investor.ptc.com. o $2.4 billion in total revenue, growing mid-teens o $2.2 billion of software revenue, growing mid-teens o 85% subscription mix, yielding 95% recurring software revenue o Non-GAAP operating margin of 37% o Non-GAAP EPS of $6.50, and o Free cash flow of $850 million o Given the compounding benefit of a subscription business model, we expect operating margin, EPS, and free cash flow growth will accelerate significantly beginning in fiscal ’19, including between 400 to 600 basis points of annual operating margin expansion through fiscal ’21. Please note that these future targets do not take into consideration the impact of ASC 606, which PTC will adopt as of October 1, 2018 (fiscal year 2019). Important Disclosures Reporting metrics and non-GAAP definitions – Management believes certain operating measures and non- GAAP financial measures provide additional meaningful information that should be considered when assessing our performance. These measures should be considered in addition to, not as a substitute for, the reported GAAP results. Software licensing model – The majority of our software sales historically were perpetual licenses, where customers own the software license. Typically, our customers choose to pay for ongoing support, which includes the right to software upgrades and technical support, and attach rates on support are in the high 90% range with retention rates also in the 90% range. For fiscal 2016, fiscal 2017, and fiscal 2018, a majority of our new license bookings have consisted of ratably recognized subscriptions. Under a subscription, customers pay a periodic fee for the continuing right to use our software, including access to technical support. They may also elect to use our cloud services and have us manage the application. We began offering subscription pricing as an option for most PTC products in Q1 FY’15, and as of January of 2018, we no longer offer new perpetual licenses in the Americas and Western Europe, except for Kepware. We believe subscription has proved attractive to customers as it: (1) increases customer flexibility and opportunity to change their mix of licenses; (2) lowers the initial purchase commitment; and (3) allows customers to use operating rather than capital budgets. Over a four to five-year period we believe the value of a subscription is likely to exceed that of a perpetual license, assuming similar seat counts. However, initial revenue, operating margin, and EPS will be lower as revenue is recognized ratably in a subscription, rather than up front. Bookings Metrics We offer both perpetual and subscription licensing options to our customers, as well as monthly software rentals for certain products. Given the difference in revenue recognition between the sale of a perpetual software license (revenue is recognized at the time of sale) and a subscription (revenue is deferred and recognized ratably over the subscription term), we use bookings for internal planning, forecasting and reporting of new license and cloud services transactions. In order to normalize between perpetual and subscription licenses, we define subscription bookings as the subscription annualized contract value (subscription ACV) of new subscription bookings multiplied by a conversion factor of 2. We arrived at the conversion factor of 2 by considering a number of variables including pricing, support, length of term, and renewal rates. We define subscription ACV as the total value of a new subscription booking divided by the term of the contract (in days) multiplied by 365. If the term of the subscription contract is less than a year, the ACV is equal to the total contract value. Beginning in Q3’18, minimum ACV commitments under our Strategic Alliance Agreement with Rockwell Automation are included in subscription ACV if the period-to- date minimum ACV commitment exceeds actual ACV sold under the Agreement. Page 11 of 14

License and subscription bookings equal subscription bookings (as described above) plus perpetual license bookings plus any monthly software rental bookings during the period. Total ACV equals subscription ACV (as described above) plus the annualized value of incremental monthly software rental bookings during the period. Because subscription bookings is a metric we use to approximate the value of subscription sales if sold as perpetual licenses, it does not represent the actual revenue that will be recognized with respect to subscription sales or that would be recognized if the sales were perpetual licenses, nor does the annualized value of monthly software rental bookings represent the value of any such booking. Navigate Allocation -- Revenue and bookings for Navigate™, a ThingWorx-based IoT solution for PLM are allocated 50% to Solutions and 50% to IoT. Annualized Recurring Revenue (ARR) - To help investors understand and assess the success of our subscription transition, we provide an Annualized Recurring Revenue operating measure. Annualized Recurring Revenue (ARR) for a given quarter is calculated by dividing the portion of non-GAAP software revenue attributable to subscription and support for the quarter by the number of days in the quarter and multiplying by 365. (A related metric is Subscription ARR, which is calculated by dividing the portion of non- GAAP revenue attributable to subscription for the quarter by the number of days in the quarter and multiplying by 365.) ARR should be viewed independently of revenue and deferred revenue as it is an operating measure and is not intended to be combined with or to replace either of those items. ARR is not a forecast of future revenue, which can be impacted by contract expiration and renewal rates, and does not include revenue reported as perpetual license or professional services revenue in our consolidated statement of income. Subscription and support revenue and ARR disclosed in a quarter can be impacted by multiple factors, including but not limited to (1) the timing of the start of a contract or a renewal, including the impact of on-time renewals, support win-backs, and support conversions, which may vary by quarter, (2) the ramping of committed monthly payments under a subscription agreement over time, and (3) multiple other contractual factors with the customer including other elements sold with the subscription or support contract, and (4) the impact of currency fluctuations. These factors can result in variability in disclosed ARR. Foreign Currency Impacts on our Business – We have a global business, with Europe and Asia historically representing approximately 60% of our revenue, and fluctuation in foreign currency exchange rates can significantly impact our results. We do not forecast currency movements; rather we provide detailed constant currency commentary. We employ a hedging strategy to limit our exposure to currency risk. Constant Currency Change Measure (YoY CC) – Year-over-year changes in revenue on a constant currency basis compare reported results excluding the effect of any hedging converted into U.S. dollars based on the corresponding prior year’s foreign currency exchange rates to reported results for the comparable prior year period. Important Information about Non-GAAP References PTC provides non-GAAP supplemental information to its financial results. We use these non-GAAP measures, and we believe that they assist our investors, to make period-to-period comparisons of our operational performance because they provide a view of our operating results without items that are not, in our view, indicative of our core operating results. We believe that these non-GAAP measures help illustrate underlying trends in our business, and we use the measures to establish budgets and operational goals, communicated internally and externally, for managing our business and evaluating our performance. We believe that providing non-GAAP measures affords investors a view of our operating results that may be more easily compared to the results of peer companies. In addition, compensation of our executives is based in part on the performance of our business based on these non-GAAP measures. However, non- GAAP information should not be construed as an alternative to GAAP information as the items excluded from the non-GAAP measures often have a material impact on our financial results and such items often Page 12 of 14

recur. Management uses, and investors should consider, non-GAAP measures in conjunction with our GAAP results. Non-GAAP revenue, non-GAAP operating expense, non-GAAP operating margin, non-GAAP gross profit, non-GAAP gross margin, non-GAAP net income and non-GAAP EPS exclude the effect of the following items: fair value of acquired deferred revenue, fair value adjustment to deferred services cost, stock-based compensation, amortization of acquired intangible assets, acquisition-related and other transactional charges included in general and administrative costs, restructuring charges, headquarters relocation charges, and income tax adjustments. Additional information about the items we exclude from our non- GAAP financial measures and the reasons we exclude them can be found in “Non-GAAP Financial Measures” beginning on page 33 of our Annual Report on Form 10-K for the fiscal year ended September 30, 2017. A reconciliation of non-GAAP measures to GAAP results is provided within these prepared remarks. PTC also provides information on “free cash flow” and “adjusted free cash flow” to enable investors to assess our ability to generate cash without incurring additional external financings and to evaluate our performance against our announced long-term goal of returning approximately 40% of our free cash flow to shareholders via stock repurchases. Free cash flow is net cash provided by (used in) operating activities less capital expenditures; adjusted free cash flow is free cash flow excluding restructuring payments and certain identified non-ordinary course payments. Free cash flow and adjusted free cash flow are not measures of cash available for discretionary expenditures. Forward-Looking Statements Statements in this press release that are not historic facts, including statements about our fourth quarter and full fiscal 2018 targets, and other future financial and growth expectations and targets and anticipated tax rates, are forward-looking statements that involve risks and uncertainties that could cause actual results to differ materially from those projected. These risks include: the macroeconomic and/or global manufacturing climates may deteriorate; customers may not purchase our solutions or convert existing support contracts to subscription when or at the rates we expect; our businesses, including our Internet of Things (IoT) business, may not expand and/or generate the revenue we expect; foreign currency exchange rates may vary from our expectations and thereby affect our reported revenue and expense; the mix of revenue between license & subscription solutions, support and professional services could be different than we expect, which could impact our EPS results; our transition to subscription-only licensing in the Americas and Western Europe could adversely affect sales and revenue; sales of our solutions as subscriptions may not have the longer-term effect on revenue and earnings that we expect; bookings associated with minimum ACV commitments under our strategic alliance agreement with Rockwell Automation may not result in subscription contracts sold through to end-user customers; the equity purchase by Rockwell Automation and entry into an accelerated share repurchase agreement may not occur when or as we expect; we may be unable to expand our partner ecosystem as we expect and our partners may not generate the revenue we expect; we may be unable to improve performance in Japan when or as we expect; we may be unable to generate sufficient operating cash flow to return 40% of free cash flow to shareholders and other uses of cash or our credit facility limits or other matters could preclude share repurchases. In addition, our assumptions concerning our future GAAP and non-GAAP effective income tax rates are based on estimates and other factors that could change, including the geographic mix of our revenue, expenses and profits. Other risks and uncertainties that could cause actual results to differ materially from those projected are detailed from time to time in reports we file with the Securities and Exchange Commission, including our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q.

As we are profitable on a non-GAAP basis, the 2018 and 2017 non-GAAP tax provisions are being calculated assuming there is no valuation allowance. Income tax adjustments reflect the tax effects of non-GAAP adjustments which are calculated by applying the applicable tax rate by jurisdiction to the non-GAAP adjustments listed above. We have recorded the impact of the Tax Cuts and Jobs Act in our Q1'18 GAAP earnings, resulting in a non-cash benefit of approximately $7 million. In Q3’18, we increased the non-cash benefit by approximately $5 million to reflect additional guidance on the state tax implications of the Act. We have excluded this benefit from our non-GAAP results. Page 14 of 14
