Thanks, Jim, and good afternoon, everyone. Before I review our results I'd like to note that I'll be discussing non-GAAP results and guidance and ARR references will be in both constant currency and as reported. Turning to slide 15. In Q1 2023 our constant currency ARR was $1.6 billion, up 15% year-over-year and exceeded guidance. On an organic constant currency basis excluding Codebeamer, our ARR was $1.59 billion, up 14% year-over-year. As Jim explained our top line strength in Q1 was broad-based. We're executing well against our strategy and we're continuing to improve upon the strong market position that we have. Our SaaS businesses saw continued solid ARR growth in Q1 as well. On an as-reported basis we delivered 11% ARR growth, 10% organic due to the impact of FX headwinds. Currency fluctuations were positive in Q1 of 2023 and our as reported ARR was $60 million higher than our constant currency ARR. However, on a year-over-year basis currency fluctuations were still a meaningful headwind. Moving on to cash flow. Our results were strong with Q1 coming in ahead of our guidance across all metrics. While it was great to see favorable FX movements during Q1, there was no impact to free cash flow from FX. Our free cash flow performance in Q1 was driven by strong execution based on a foundation of solid collections and cost discipline. Our cash from operations also came in ahead of guidance by $11 million, due to a combination of free cash flow outperformance and the timing of capital expenditures which were $9 million in Q1, compared to our guidance of $5 million. When assessing and forecasting our cash flow, it's important to remember a few things. The majority of our collections occur in the first half of our fiscal year. Q4 is our lowest cash flow generation quarter. And on an annual basis, free cash flow is primarily a function of ARR, rather than revenue. Q1 revenue of $466 million increased 2% year-over-year and was up 9% year-over-year on a constant currency basis. In Q1 recurring revenue grew by $12 million, perpetual license revenue grew by $5 million and professional services revenue declined by $9 million year-over-year. The decline in professional services revenue is consistent with our strategy to transition some of our professional services talent and revenue to DxP our partner for Windchill+ lift-and-shift projects. As we've discussed previously, revenue is impacted by ASC 606, so we do not believe that revenue is the best indicator of our underlying business performance, but we'd rather guide you to ARR as the best metric to understand our top line performance and cash generation. Before I move on to the balance sheet, I'd like to provide some color on our non-GAAP operating margin, as I did last quarter. Compared to, Q1 2022 our non-GAAP operating margin expanded by approximately 100 basis points to 36% in Q1 of 2023. We continue to caution that because revenue is impacted by ASC 606 other derivative metrics such as gross margin, operating margin, operating profit and EPS are all impacted as well. Still, it's worth mentioning, that we're benefiting from the work that we've done to optimize our cost structure in fiscal 2022. On a year-over-year basis in Q1, we continue to grow our top line at a faster rate than our spending and delivered significantly higher ARR and free cash flow. Moving to slide 16, we ended the first quarter with cash and cash equivalents of $388 million. Our gross debt was $1.36 billion with an aggregate interest rate of 4.3%. Looking forward, in Q2, in conjunction with the ServiceMax acquisition, we took out a $500 million term loan and increased the size of our revolving credit facility from $1 billion to $1.25 billion. The net of new borrowings and debt pay down in Q2, should leave us with $1 billion in high-yield notes, the $500 million term loan and approximately $450 million drawn on the revolver at the end of the quarter. As a reminder, we also have a second payment for the ServiceMax transaction, due in October 2023 of $650 million. We intend to fund this with cash on hand and our revolving credit facility. This deferred payment is included in debt on our balance sheet and is factored into our debt-to-EBITDA ratio. We expect our debt-to-EBITDA ratio to be approximately 3.4 times, at the end of Q2. We should be around three times levered by Q4 and below three times throughout fiscal 2024 and into fiscal 2025, as we continue to pay down debt. To help you with your models, in fiscal 2023 as it relates to cash flow, we expect total cash interest payments of approximately $85 million. And as it relates to the P&L, we expect interest expense of approximately $125 million. Given the interest rate environment, we expect to prioritize paying down our debt in fiscal 2023 and 2024. We'll pause, our share repurchase program. And in fiscal 2023, we expect our diluted share count to increase by a little under, one million shares. We expect to have substantially reduced our debt by the end of fiscal 2024 and we'll then revisit the prioritization of debt paydown and share repurchases. Despite this interruption, our long-term goal assuming our debt-to-EBITDA ratio is below three times, remains to return approximately 50% of our free cash flow to shareholders via share repurchases, while also taking into consideration the interest rate environment and strategic opportunities. Next slide 17 shows our ARR by product group. In the constant currency section on the top half of the slide, we used FX rates as of September 30, 2022 to calculate ARR for all periods. You can see on the slide, how currency dynamics have resulted in differences between our constant currency ARR and as-reported ARR over the past five quarters. Exchange rates continued to move materially in Q1 2023 causing a difference between constant currency ARR results and our as-reported ARR results. Based on the exchange rates, at the end of Q1 2023, our as-reported ARR in Q2 of 2023 would be higher by approximately $62 million compared to the midpoint of our constant currency guidance and fiscal 2023 as-reported ARR would be higher by approximately $67 million compared to our constant currency guidance midpoint. We report both actual and constant currency results and FX fluctuations can obviously have a material impact on actuals. But remember that, we provide ARR guidance on a constant currency basis. If exchange rates fluctuate significantly between the end of Q1 and in the end of Q2 2023 the impact to our as-reported ARR would also change. We believe constant currency is the best way to evaluate the top line performance of our business, because it removes currency fluctuations from the analysis, positive or negative. Given the sharp moves that, we've seen recently, I thought it would be useful to provide an updated ARR sensitivity rule of thumb on slide 18. In addition to the US dollar, we transact in euro, yen and more than 10 other additional currencies. Using currency rates at the end of Q1, the impact of a $0.10 change in the euro-to-USD rate would be $39 million positive or negative, and the impact of a ¥10 change in the USD-to-yen rate would be $9 million again positive or negative. And of course, the estimated dollar impact to ARR is dependent on the size of the ARR base. With that, I'll take you through our guidance on slide 19. For our ARR guidance amounts, we're using FX rates as of September 30, 2022. The previous guidance shown on this slide is from our November 2022 Investor Day presentation, and includes ServiceMax. For fiscal 2023, we expect constant currency ARR growth of 22% to 25%, which corresponds to a fiscal 2023 constant currency ARR guidance range of $1.91 billion to $1.96 billion. This narrowed range is based on two primary factors. First, we took up the bottom end of the 10% to 14% guidance range we provided on our Q4 earnings call, which excluded ServiceMax. While we saw some incremental macro-driven booking softness in our first quarter, this was partially offset by better-than-planned churn and our guidance contemplated the potential for a much bigger impact than what we saw, and we actually finished $3 million above the high end of our Q1 2023 ARR guidance range. So based on our strong Q1 results and forecast for the year, while still being mindful of the macro environment, we feel comfortable taking up the lower end of the range, which still allows for continued softening due to the macro environment. Secondly, the other update to guidance is adding approximately $170 million for ServiceMax compared to our Investor Day assumption, which was for approximately $175 million. There's a few reasons we're doing this, which include. First, ServiceMax' fiscal quarters ended one month later than ours. As we all know, the final month of a quarter in a software company is really when the magic happens. So, while I think that ultimately their results will align with PTC's quarter-end hockey stick, I also think it's prudent to assume it may take a few quarters to align selling and customer buying behavior. Second, as you know Salesforce.com is a go-to-market partner with ServiceMax for its Asset 360 product. Salesforce just announced a fairly sizable reduction in force. And while we do not know if or how this may impact ServiceMax business in the coming months, we feel it's a valid concern which we want to account for in our guidance. And third, frankly, the uncertainty of the macro environment applies to ServiceMax as well. So, it's primarily for these three reasons that we're derisking the ServiceMax guidance for fiscal 2023 and adding $170 million to our now updated 11% to 14% guidance range. With a strong Q1 behind us and given our pipeline and forecast and how we've set our guidance ranges, we believe we're well-positioned to achieve our fiscal 2023 ARR guidance. Note that we expect modestly more deferred ARR to become ARR in fiscal 2023 than in fiscal 2022. And our churn in Q1 was lower than planned. In dollar terms, churn was actually lower in Q1 2023 than it was in Q1 2022 and that's against a bigger base of ARR. For Q2, we're guiding constant currency ARR to be in the range of $1.79 billion to $1.81 billion. At the midpoint, this equates to 25% constant currency growth. I'll discuss our Q2 guidance in more detail on the next slide. On cash flows for fiscal 2023, we raised our guidance. We now expect cash from operations of approximately $595 million, up 37%; and free cash flow of approximately $575 million up approximately 38%. Compared to the guidance we provided a quarter ago, our updated $575 million target for free cash flow factors in our strong execution and results in Q1, $5 million from the ServiceMax acquisition which we already communicated at our Investor Day, as well as an increase from FX tailwinds for the remainder of the year. Assuming we hit our Q2 free cash flow target, we'll be at approximately 65% of our full year target similar in the past two years. Our CapEx assumption for fiscal 2023 is $20 million. Therefore relative to our free cash flow guidance of $575 million, we're guiding to cash from operations of $595 million. For Q2, we're guiding to free cash flow of approximately $200 million. We expect approximately $5 million of CapEx in Q2 and therefore, our cash from operations guidance is approximately $205 million. As you model the quarters of fiscal 2023, keep in mind, we expect the quarterly distribution of full year cash flow results to follow a similar pattern as in fiscal 2022 and fiscal 2021 with over 60% of cash flow in the first half of the year and Q4 being our lowest cash flow generation quarter. Moving on to revenue guidance, we raised -- which we raised from our November 2nd guidance, primarily because of ServiceMax and currency. For fiscal 2023, we expect revenue of $2.07 billion to $2.15 billion which corresponds to a growth rate of 7% to 11%. ASC 606 makes revenue fairly difficult to predict in the short-term for on-premise subscription companies, hence the wide range. More importantly, revenue does not influence ARR or cash generation as we typically bill customers annually upfront regardless of term lengths. Turning to slide 20. Here is an illustrative constant currency ARR model for Q2 2023. You can see our results over the past nine quarters and in the far-right column, we've modeled the midpoint of our Q2 constant currency ARR guidance range. Because our ARR tends to see some seasonality, the most relevant compare is Q2 of 2022. The illustrative model indicates, that to hit the midpoint of our Q2 2023 guidance range of $1.8 billion, we need ServiceMax ARR of approximately $160 million, which is what we said at Investor Day and believe is a reasonable target. On top of the ServiceMax contribution, we need to add $37 million of organic ARR on a sequential basis. This is $19 million less than the $56 million we added in Q2 of fiscal 2022. In percentage terms, we need 2% organic sequential ARR growth to hit our guidance midpoint for Q2, which is at the lower end of what we've delivered over the past nine quarters. All things considered, we believe we've set our Q2 2023 constant currency ARR guidance range prudently. Turning to Slide 22. I'll conclude my prepared remarks today by highlighting, that we're prepared for a storm and expect to be resilient in the face of one. From a top line perspective, we serve industrial product companies. And R&D, at those companies tends to be quite resilient, so we have a supportive top line backdrop. We also have a subscription business model and our products are very sticky with our customers. Just as importantly from a cost perspective, we've already battened down the hatches. In addition, to the cost optimization work we did last year, we've already slowed planned hires and backfills as we head into Q2. Nevertheless, as we've said in the past, we don't have a Pollyanna-type view when it comes to the macro situation. We have a strong track record of disciplined operational management. And if the macro situation gets meaningfully worse, you can expect us to moderate our spending further, to better align spending with market realities and mitigate the impact on our fiscal 2023 cash flow results. For example, variable compensation would automatically adjust. And depending on the magnitude of the downturn, we would also be incrementally more cautious on hiring and marketing spend travel, et cetera. On the other hand, if the macro situation improves and/or if the dollar weakness continues, this would be favorable for our cash generation. And in that scenario, we would have the optionality to invest more aggressively in our business. There's no question that the macro environment is hard to predict. Nevertheless, we've contemplated one strong quarter of fiscal 2023 -- completed one strong quarter of fiscal 2023 and are positioned to continue producing attractive financial results, based on our strong product and market position coupled with solid execution and prudent financial management. With that, I'll turn the call over to the operator to begin Q&A.
