Good morning, and welcome to the AngioDynamics Fourth Quarter and Fiscal Year 2023 Earnings Call. At this time, all participants are in a listen-only mode. A question-and-answer session will follow the formal presentation. As a reminder, this conference call is being recorded. The news release detailing AngioDynamics' fourth quarter and fiscal year 2023 results crossed the wire earlier this morning and is available on the company's website. This conference call is also being broadcast live over the Internet at the Investors section of the company's website at www.angiodynamics.com, and the webcast replay of the call will be available at the same site approximately one hour after the end of today's call. Before we begin, I would like to caution listeners that during the course of this conference call, the company will make projections or forward-looking statements regarding future events, including statements about expected revenue, adjusted earnings, and gross margins for fiscal year 2024 as well as trends that may continue. Management encourages you to review the company's past and future filings with the SEC, including, without limitation, the company's Forms 10-Q and 10-K, which identifies specific factors that may cause the actual results or events to differ materially from those described in the forward-looking statements. The company will also discuss certain non-GAAP financial measures during the call. Management uses these measures to establish operational goals and review operational performance and believes that these measures may assist investors in analyzing the underlying trends in the company's business over time. Investors should consider these non-GAAP measures in addition to, not as a substitute for or as superior to, financial reporting measures prepared in accordance with GAAP. A slide package offering insight into the company's financial results is also available on the Investors section of the company's website under Events & Presentations. This presentation should be read in conjunction with the press release discussing the company's operating results and financial performance during this morning's conference call. I'd now like to turn the call over to Jim Clemmer, AngioDynamics' President and Chief Executive Officer. Mr. Clemmer?

Good morning, everyone, and thank you for joining us for AngioDynamics' fourth quarter fiscal 2023 earnings call. Joining me on today's call is Steve Trowbridge, AngioDynamics' Executive Vice President and Chief Financial Officer, who will provide a detailed analysis of our fourth quarter and fiscal year financial performance and our fiscal 2024 guidance. FY '23 saw continued progress against our long-term strategy, and we have already had an exciting start to FY '24 with the strategic divestiture that we announced on June 8 and are looking forward to delivering solid proforma revenue growth this year. We ended the fourth quarter with revenue of $91.1 million, representing growth of 4.7% year-over-year, led by growth of 17.2% from our Med Tech segment. For the full fiscal year, our revenue was $338.8 million, representing growth of 7.1% over the previous year. Our Med Tech segment grew 22.8% and our Med Device segment grew 1.9%. We are now 24 months into our 36-month plan and we are progressing at or ahead of our long-term revenue targets that we provided in July of 2021. We are very pleased with the results from our Auryon PAD business, as we finished the year with revenue of $41.1 million, which was an increase of 41% over FY 2022. We are continuing to gain share in this category based upon the science behind Auryon, which provides physicians with the power they seek and the safety they require when treating patients with peripheral artery disease. In less than three years since launch, Auryon is becoming a trusted tool, and many physicians are also sharing their positive experiences with Auryon. In addition, we are excited about early findings published in the Cardiovascular Revascularization Medicine outlining the ability of the Auryon laser to fracture medial arterial calcification in small vessels. We will continue to invest in this unique platform, and we have plans to launch a venous thrombectomy version of Auryon, as well as pursue a pathway to launch a coronary atherectomy version of Auryon in the future. These launches will exponentially increase the addressable markets in which Auryon competes. We also anticipate receiving CE Mark for Auryon in the first half of fiscal 2024. Our NanoKnife business grew nearly 19% in FY '23, and most importantly, sales of probes grew 27% over prior year, ahead of our goal. NanoKnife growth from our international team came as they established new relationships with partners who assist in supporting our procedures. And our U.S. growth was driven by continuing interest in this technology as more physicians become aware of our DIRECT and PRESERVE trials. We are really excited to report that our PRESERVE trial, studying the use of NanoKnife to treat intermediate-risk prostate cancer, is now fully enrolled, and we are on track to finish our study and present our results to the FDA in calendar Q3 of 2024. Additionally, in July in the U.K., the National Institute for Health and Care Excellence, or NICE, Interventional Procedures Committee finalized guidance for IRE in prostate, moving NanoKnife from research-only to special arrangements. We believe this change in guidelines will help improve access for patients within the U.K. and represents another positive step towards our ultimate goal of having the NanoKnife system being recognized as a standard-of-care for patients with intermediate-risk prostate cancer. NICE guidance is recognized as a leading authority in healthcare decision-making due to its rigorous evaluation process and evidence-based approach, and we are encouraged knowing that many regulatory bodies around the world may consider NICE guidance when reviewing healthcare interventions for approvals or when making policy decisions. We believe that NanoKnife has the potential to be one of the most important breakthroughs for men who qualify for a focal treatment approach to their disease by driving beneficial outcomes and offering significant quality-of-life benefits. It also has the potential to open up a roughly $700 million market here in the U.S., and potentially a $2 billion market globally for those intermediate-risk patients. In FY '23, our international business grew an impressive 12% over the prior year and 14% on a constant currency basis. Growth came both from our Med Tech and Med Device segments, and was also very balanced throughout the geographies that we support. Our team is strong, and we will continue to grow in international markets through our strategy that employs key partners to support our products, continued exposure through our series of scientific symposiums, and further expansion of our Med Tech portfolio as we gain important regulatory approvals around the globe. We believe this is the right approach, and it allows us to leverage our partners in both the Med Tech and Med Device segments without a significant investment that would be required to build out a fully direct global salesforce. Our mechanical thrombectomy business, which includes AngioVac and AlphaVac, finished the fiscal year with growth of 9.7% over the prior year, which was below our expectations. We believe that we have great products that offer excellent clinical outcomes with strong patient safety profiles, and we will be launching enhancements to these products that incorporate feedback and insights from our customers and other interested physicians. As we have previously discussed, we are in the early stages of developing our product portfolio in the thrombectomy space. Today, our AlphaVac product offerings are utilized in the large bore subsection of the market and are subject devices for our APEX study. Looking ahead, we are preparing to launch a new version of our Auryon product for use in the lower extremities segment of the venous thrombectomy market. We believe that this will be a disruptive technology, giving customers an option to treat small-vessel clots using the power, energy, and aspiration capabilities of Auryon, which will be unlike anything else currently on the market. We are planning to launch this product in calendar year 2025. On the clinical front, we are also pleased to report that our APEX study, evaluating AlphaVac F18 as a treatment for pulmonary embolism, is more than 50% enrolled, and we expect to complete enrollment this winter and submit our results to the FDA in the first half of calendar year 2024. To achieve our expectations for our thrombectomy business, we are continuing to improve our customer messaging, our training, and our field performance, especially for AngioVac. As we discussed on last quarter's call, we are taking steps to address each of these areas to ensure that this important business meets our expectations in the future. The thrombectomy opportunity is very important to our company, and we are confident that our unique designs and, ultimately, our comprehensive offering will enable us to drive significant profitable growth in this business for years to come, even with strong competition in the market. Our Med Device segment grew 1.9% over the prior year, in line with the expectations that we set during our Investor & Technology Day in July of 2021. This important segment will continue to provide a stable cash generation and earnings profile as it does not require the same level of annual investment as our Med Tech platforms require. On June 8, we announced the divestiture of our Dialysis and BioSentry businesses to Merit Medical. These businesses were divested for two reasons: first, it will allow us to focus on fewer product categories and allocate our resources to areas that are better aligned with our long-term portfolio objectives; and second, we were able to strengthen our balance sheet, and today, we are in a strong net cash position with no need to utilize outside sources to fund our investments in the future. We have always said that we would be active portfolio managers, and this move shows that when value-generating opportunities arise to better align our portfolio with our long-term strategic goals, we'll execute upon them. And finally, on June 1, 2023, in our ongoing IP lawsuit with BD Bard, the United States District Court in Delaware granted our motion for a judgment as a matter of law, declaring that the patents asserted by Bard are invalid, as anticipated, indefinite and ineligible and not infringed. The decision is consistent with our position and our arguments in the case since it was brought in 2015. We expect this decision to be appealed by Bard, but we believe that it is supported by the facts and reflects our meritorious defenses and positions in the other cases pending with Bard in Delaware and Utah. While the case may not be definitively over yet, we believe that the judge's ruling is accurate and gets us one step closer to finally putting this matter to rest. Before I turn the call over to Steve, I'd like to thank our team here at AngioDynamics for their commitment to executing upon our strategy and becoming a high-growth profitable medtech company. We are excited about last month's divestiture announcement and the fact that we are now in a net cash position with a simpler, more well-defined portfolio.

Thanks, Jim. Good morning, everyone. Before I begin, I'd like to direct everyone to the presentation on our Investor Relations website, summarizing the key items from our quarterly and fiscal year results. Our revenue for the fourth quarter of FY '23 increased 4.7% year-over-year to $91.1 million, driven by continued strength in our Med Tech platforms, including Auryon, NanoKnife, and thrombectomy. We are pleased with the growth year-over-year, particularly in light of the fact that we had a very strong Q4 last year as our capacity improvement initiatives significantly reduced the existing back order at that time. Last year's Q4 exhibited growth of 13.2% over the prior year, so our results for Q4 of FY '23 illustrate continued strong execution against our strategic plan. Med Tech revenue was $26.5 million, a 17.2% year-over-year increase, while Med Device revenue was $64.6 million, growing 0.3% compared to the fourth quarter of FY '22. For the full year 2023, our Med Tech platform grew 22.8% and our Med Device businesses grew 1.9% compared to the prior-year period. Through the first two years of our three-year plan, our Med Tech segment has grown at a CAGR of 33.1%. For the fourth fiscal quarter, our Med Tech platforms comprised 29% of our total revenue. For the full year 2023, our Med Tech platforms comprised 29% of our total revenue compared to 25% for fiscal 2022. Our Auryon platform contributed $11.8 million in revenue during the fourth quarter, growing 22% compared to last year. As Jim mentioned, we are very pleased with the trajectory of this business and are developing additional indications in the VTE space, as well as international opportunities in atherectomy that we think will open up additional significant addressable markets. Mechanical thrombectomy revenue, which includes AngioVac and AlphaVac sales, increased 3.7% over the fourth quarter of FY '22. AlphaVac revenue for the fourth quarter was $1.8 million. Both the F22 and F18 versions of AlphaVac are performing well and receiving positive physician feedback. For the full year 2023, revenue for AlphaVac was $7.2 million. AngioVac revenue was $6.1 million in the quarter, representing a decline of 8.3% over the prior year, but up sequentially from the third quarter. As Jim mentioned, AngioVac saw ongoing challenges during the year, and we've taken meaningful action to address these challenges and are committed to executing against them in '24. For the full year 2023, AngioVac revenue was $24.5 million, a decline of 8.2%. We remain confident that mechanical thrombectomy will be a significant contributor to our growth strategy, and we will continue to prioritize investments in this platform, including the new product introductions that Jim mentioned, as well as our clinical initiatives, such as the APEX PE study. NanoKnife disposable revenue during the quarter increased 28% year-over-year. For the full year 2023, sales of NanoKnife disposables grew 27.1%. We continue to see this business perform very well both in our U.S. and in international markets, and we're pleased to announce that enrollment in PRESERVE is now 100% complete. In the fourth quarter, our Med Device segment grew 0.3% year-over-year, led by strength in our angiographic products and the dialysis business. As of the end of the fourth quarter, our backlog stood at $2.7 million. For the full year 2023, our Med Device segment grew 1.9%, in line with our long-term target of 1% to 3% growth. Moving down the income statement, our gross margin for the fourth quarter of FY '23 was 50.9%, a decrease of 250 basis points compared to the year-ago period. For the full year '23, gross margin was 51.4%, a decrease of 100 basis points compared to fiscal year 2022. For the fourth quarter, Med Tech gross margin was 64.7%, a decrease of 400 basis points, and Med Device gross margin was 45.2%, a decrease of 280 basis points, each when compared to the fourth quarter of last year. For the full year, Med Tech gross margins were 64.1%, a decrease of 270 basis points, and Med Device margins were 46.4%, a decrease of 120 basis points, again, each when compared to the full year '22. As we've discussed, our strategic business model contemplates gross margin expansion as our higher-margin Med Tech segment continues to become a larger portion of our overall revenue base. And we have seen this dynamic, however, the overall impact has been mitigated by the supply chain disruptions and inflationary pressures that we've experienced over the past two years. When looking specifically at the Med Tech segment, gross margins remained significantly ahead of overall corporate margins. The quarterly and year-over-year performance was negatively impacted by the revenue performance of AngioVac and increased capital placements. The paydown of the IIA royalty that we discussed in Q1 provided approximately a $1 million benefit over the course of the year, partially offsetting these headwinds. Med Device margins were positively impacted by increased productivity, but this benefit was more than offset by the continued inflationary environment, the hurdle created by the CARES Act benefit in FY '22, and the mix shift resulting from increased international growth. Turning to R&D, our research and development expenses during the fourth quarter of FY '23 was $7.9 million or 8.6% of sales, compared to $7.9 million or 9% of sales a year ago. Our disciplined investment in R&D will continue to drive growth across our key technology platforms and includes the clinical and product development spend for our Med Tech portfolio. R&D expense for the full year 2023 was $29.9 million or 8.8% of sales compared to $30.7 million or 9.7% of sales in the previous year. For FY '24, we anticipate R&D spend to target 9% to 11% of sales. When accounting for the divestiture of our Dialysis and BioSentry businesses that was completed in June of this year, R&D spend in FY '23 on a proforma basis was 9.6% of sales. SG&A expense for the fourth quarter of FY '23 was $36.5 million, representing 40.1% of sales compared to $37.9 million or 43.6% of sales a year ago. For the full year 2023, SG&A expense was $144.3 million, representing 42.6% of sales compared to $133.8 million, representing 42.3% of sales in FY '22. For FY '24, we anticipate SG&A spend to target 45% to 48% of revenue. When accounting for the divestiture, SG&A spend in FY '23 on a proforma basis was 47.1% of sales. As we stated at the time of the divestiture, there was not a significant amount of direct costs that were associated with the Dialysis and BioSentry businesses. As a result, our expectations for SG&A spend in FY '24 do include leverage with respect to G&A spending, but also include an increase as a percent of sales in sales and marketing. Our adjusted net income for the fourth quarter of FY '23 was $0.7 million or adjusted earnings per share of $0.02 compared to an adjusted net income of $0.3 million or adjusted earnings per share of $0.01 in the fourth quarter of last year. For the full year 2023, adjusted net loss was $2.4 million or adjusted loss per share of $0.06 compared to an adjusted net loss of $0.2 million or approximately breakeven on a per share basis a year ago. As a reminder, our adjusted earnings per share in FY '22 included a $4.2 million or $0.08 per share benefit related to the reimbursement of certain expenses under the employee retention credit as part of the CARES Act, with no corresponding benefit in our FY '23 numbers. GAAP net income, as reported in our earnings release this morning, included a goodwill impairment related to our Med Device segment in connection with the divestiture of our Dialysis and BioSentry businesses. These businesses that were divested on June 8, 2023, subsequent to our fiscal year end were accounted for as held-for-sale as of May 31, 2023. So as a result, we reported a goodwill impairment during the fiscal fourth quarter ended May 31, 2023. The impairment resulted in a loss of $14.5 million or $0.37 per share on a GAAP basis. Due to the timing of the transaction, the loss is recorded in our fourth fiscal quarter for FY '23, but the offsetting gain on the sale of the assets won't be recorded until our first fiscal quarter of FY '24. Result is a large GAAP loss in the fourth quarter of '23, but then it will be a larger GAAP gain in the first quarter of FY '24. Adjusted EBITDA in the fourth quarter of FY '23 was $7.9 million compared to $6.2 million in the fourth quarter of FY '22. For the full year '23, adjusted EBITDA was $22.6 million compared to $20.9 million in FY '22, representing year-over-year growth of over 8.3%. In the fourth quarter of fiscal '23, we generated $16 million in operating cash, had capital expenditures of $1.1 million and additions to Auryon placement and evaluation units of $0.5 million. At May 31, 2023, which is prior to the divestiture, we had $44.6 million in cash and cash equivalents compared to $30.1 million in cash and cash equivalents at February 28, 2023. We had $25 million outstanding under our revolving credit facility and $25 million outstanding under our delayed draw term loan at May 31, 2023, equal to the amounts outstanding under these facilities at February 28. Subsequent to quarter-end, we used part of the proceeds from the divestiture to extinguish our debt. As a result, we currently have significant cash balances and zero debt. As is always the case, we expect our first fiscal quarter to have the highest utilization of cash during the fiscal year, with cash balances building throughout the remainder of the fiscal year. So we expect to finish fiscal year 2024 with cash balances in the range of $65 million to $70 million, and we expect to be approaching cash flow positive by the end of FY '25, having utilized an aggregate of $10 million to $20 million over the two-year period. Now, said another way, immediately after the transaction when accounting for tax and deal costs, we had $90 million of cash. In June, we paid the $10 million Auryon earnout and expect to pay the next $5 million Auryon earnout by the end of our fiscal '24, with a final $5 million payment expected to occur in FY '25. So that $15 million of '24 milestone payments bring that $90-plus million down to $75 million in FY '24. We expect to end our fiscal year '24 with cash balances of $65 million to $70 million, reflecting operating cash usage of $5 million to $10 million for the year. Again, given the timing of Q1 payments and managing our working capital, Q1 will exhibit cash utilization with balances then growing throughout the year. We believe that we have more than sufficient cash to execute on our strategic initiatives, as we move to generating positive cash flow toward the end of our FY '25. In 2019, we began a transformation of AngioDynamics. The first step of the transformation was to fundamentally change our portfolio to incorporate platform technologies that can provide a unique advantage and compete in higher-growth, high-margin, large total addressable markets. We began the transformation by selling our largest business at the time, our NAMIC Fluid Management Business, and then investing a third of the proceeds from that sale to buy Eximo Medical, an early-stage Israeli startup, which led to the Auryon PAD laser. We've continued our strategic transformation reporting our business in two segments, Med Tech and Med Device, using internal R&D to launch our AlphaVac mechanical thrombectomy device and by investing in clinical initiatives to expand into specific uses, including our APEX study for PE and our PRESERVE study for the use of NanoKnife to treat intermediate-risk prostate cancer patients. In July of 2021, we articulated a goal of executing to a three-year CAGR for our Med Tech segment of 30% to 35%. Through two years of that three-year plan, our Med Tech segment has a CAGR of 33%. We've indicated that we would be active portfolio managers with the goal of focusing our company on our strategic objectives. In June of this year, we completed the divestiture of our Dialysis and BioSentry businesses, which recapitalized our balance sheet and enhanced our Med Tech focus. Gross margin expansion has proved challenging. Coming out of the COVID global pandemic, we've been impacted by the tight labor market, which has not fully rebounded. In addition, our Med Device businesses contain a wide and very product offering that leaves us under scale, and it makes us susceptible to inflationary pressures, limiting our ability to drive efficiencies. The next phase of our transformation is to address the scale and structural limitations of our operating footprint in a capital-efficient manner, and we look forward to continuing to update you on our plans and actions to drive margin enhancements in the short and medium term. Turning now to guidance. We anticipate that FY '24 revenue will be in the range of $328 million to $333 million, and we expect full year adjusted loss per share to be in the range of $0.28 to $0.34. As a reminder, this compares to fiscal year '23 proforma revenue of $306.3 million and proforma loss per share of $0.43 when excluding the recently divested assets. Those divested assets carry very little direct cost, which means, while the transaction provided significant cash proceeds, it is dilutive to both corporate margins and at a larger clip to the earnings line. We expect FY '24 gross margin to be in the range of 50% to 52% compared to proforma FY '23 gross margin of 50.5%. For FY '24, we expect Med Tech revenue growth in the range of 20% to 25% and Med Device revenue growth in the range of 1% to 3%. We expect Med Tech gross margins in the range of 63% to 65% and Med Device gross margins in the range of 43% to 45%.

Thanks, Steve. Our FY '23 and the subsequent divestiture have positioned us to continue investing and growing the business in FY '24, while also managing our cost structure and looking to expand the margin profile of our business. We're excited with where we are today, while also looking forward to introducing new products and new indications to the market and opening up additional addressable markets for our existing products. Our team did a commendable job in FY '23, shown true dedication to our strategy, and I'm very proud of what they've accomplished in the transformation of AngioDynamics so far. When we sold NAMIC in 2019, we told you that we were going to be a different company, one driven by innovation, science, and data generation. Since then, we have taken the necessary steps and made the necessary investments to set AngioDynamics up to win. This doesn't take place overnight and is part of the organizational journey when becoming a science-based company. The most successful companies in medtech got to where they are by delivering innovation to the customer and to the patient. We are committed to that process of delivering innovation and to challenging the current standards of care. We believe that our portfolio will do just that over the next five years, fueled by our investments in R&D, clinical expansion, and sales and marketing resources. These investments and the important research that is being done today are the fuel that will power us to significantly expand our presence in large addressable markets and generate profitable growth for years to come. With that, operator, I'd like to turn the call back and take questions.

Thank you. We'll now be conducting a question-and-answer session. And our first question comes from the line of Jason Bedford from Raymond James. Please proceed with your questions.

Good morning. Can you hear me okay, guys?

Hi, Jason. Good morning. Yes.

Good morning. Regarding the EPS guidance, it may catch some people off guard, but it aligns well with your statements about the profitability of the divested business. I believe a key issue is that you haven't yet addressed the fixed costs associated with the divested business. So, my question is: when will you begin to reduce some of these costs and adjust the cost structure for approximately $30 million less in revenue?

Yes, it's a good question, Jason. As we had indicated when we first announced the divestiture, there weren't a lot of direct costs that come with this business, but we are going to be tackling those costs. And so the guide partially reflects the fact that right off the bat, we're going to continue to run our business and then over time, look to right-size it as we get some operating experience. So I do expect you're going to see some of those costs come out, but you're also going to see us continue to grow into the structure that we have. So I think it's going to be a little bit of a timing process, but also we did make that choice to monetize those assets and recapitalize the balance sheet and we made that trade-off a little bit for operating profit during the year.

Okay. And just as it relates to the deal, should we expect more divestitures in fiscal 2024?

Hi, Jason, it's Jim. As we've said before, we've tried to let our investors see our focus strategically towards our Med Tech platform. That still comprises only about 30% of our company's revenue. So we want to continue to focus there. We have a lot of moving parts here. So it's easier to operate the company with fewer moving parts, easier to focus our investments going forward. And some of those things were challenged, Jason, during COVID, with supply chain challenges when you have this many products and categories that you serve. So we'll watch and see. We've mentioned we'll be active portfolio managers, and we'll make sure that we do the right thing to keep our strategic goals in line, yet still back to what Steve said, making sure that our growth comes with a profitability that investors will be pleased to see. It may take a little bit of time to get there. We've tried to outline that to you guys, but we'll be active in our portfolio management.

Okay. And just on the cash, obviously, the cash position has flipped here. You're burning a little bit of cash, not a ton. But can you just walk through your plans for capital allocation? What are you going to do with the cash?

Yes. Good question. I think what our current projection is to take a little bit of time, six, eight, 10 months and keep the cash. We want to be able to illustrate externally that we can manage the business in accordance with the guidance that we gave today. We want to show you that we're not burning a significant amount of cash. And then as we exit that timeframe and we're getting back to the cash flow positive, that's when we'll be a little bit more clear in terms of indications at that time of use of the cash. As of right now, we don't have any expectations of going out and doing divestitures or spending that cash. We're going to continue to keep that cash and then illustrate our operating model before we move into uses of that cash.

Okay. And I'll just ask one more and then jump back in queue. On thrombectomy, you mentioned that you'll be launching enhancements, product enhancements. Can you just walk through the timing on those enhancements?

Yes, Jason, it's Jim. Just some of the feedback we've received now that AngioVac has been on the market for just over a year. We've got some great feedback on how it works, the safety and efficacy that it gives to the physicians, but you always get good feedback. So we're looking at making some product enhancements as anybody would do on a 2.0 version, adding some things. We expect some of those enhancements to be launched in calendar 2024. I'm sorry, Jason, calendar 2024. I get confused on our fiscal year. Next calendar year.

Okay. Thank you.

Thanks, Jason.

Our next question is coming from the line of Bill Plovanic with Canaccord Genuity. Please proceed with your question.

Great, thanks for taking my questions. Good morning. First off, just the Auryon product, the uses seem to be expanding as you talk about the thrombectomy and then going into coronary. Just trying to kind of get a wrap my head around. One, as we look at the business today, that was really solid growth. How much of that was U.S. versus OUS driven? How much of that is outpatient versus OBL? And then just two, how should we think about this strategically as you move forward? It seems like this product is becoming a bigger and bigger piece of the company's overall Med Tech franchise in finding more uses.

Yes, Bill, that's a great question. Almost all of our revenue in 2023 came from the U.S. We are currently in the process of gaining our CE mark, which we expect to achieve in the first half of this fiscal year. Some research has been conducted in Europe, and some of that has been published by various clinicians and physicians there who are quite enthusiastic about Auryon. However, most of our activity has been focused in the U.S. Currently, we are seeing a revenue mix of approximately 75% from office-based labs (OBL) and 25% from hospitals, and that hospital portion is increasing as expected. We launched the product in September 2020, and during the pandemic, access to hospitals was challenging, so our early customers were mainly OBLs. We anticipate that this mix will continue to shift towards hospitals. Regarding your question about our acquisition of Eximo Medical, we recognized its potential in the peripheral artery disease (PAD) market and understood the competitive landscape. We believe Auryon has a unique position. We are confident in its mechanism of action and its applicability to other parts of the body and other conditions. Therefore, we are excited about launching the venous version in 2025, which will enhance our thrombectomy portfolio with Auryon in that small vessel area. We also believe that, just as effective as it is for PAD, Auryon can be beneficial in coronary applications, providing the safety needed for treating coronary indications while effectively delivering energy within the vessel wall to address calcium and clot. This will be a significant part of our future strategy, as you pointed out.

Are there key studies we should monitor as we explore these new indications? Additionally, regarding the AlphaVac, it appears to be progressing slower than we initially anticipated. Until we obtain the F18 for PE, will our growth be limited? How should we approach this situation until the PE indication is available?

That's a good question. Regarding the Auryon version for thrombectomy, we will be following a 510(k) process, so not many studies will be needed for that. This is already integrated into our development and launch models. If we pursue a coronary model, there is an existing pathway, which will require more of a PMA process, leading to a study announcement as we progress. Although it will be more challenging, we have a clear path outlined by the FDA. As for AlphaVac, we achieved the revenue guidance we provided last year, in the 7% to 9% range. We gained valuable insights throughout the year and received feedback that will inform product enhancements. Overall, the product has proven to be safe and effective, and user confidence in its performance is growing. The APEX study will also help us tap into the large PE market, and currently, more than half of the subjects are enrolled, which is promising. Our immediate focus will be on educating physicians about the product's application in the current anatomy and finalizing the study. Once the study results are released, we expect to see significant growth in that market.

Okay. For my last question, could you provide the timelines for submitting data and receiving approval for the PRESERVE studies? I assume this is a 510(k). How should we think about the business impact and the timing for disseminating the data into the marketplace to potentially drive that business? Thank you for answering my questions today.

Bill, good question. So, we're excited that we've completely enrolled the study. The study has a 12-month follow-up. So you'd expect us over the course of the year until next July to complete the follow-up, compile the data, we'll submit to the FDA not long after that. And we expect really if the process goes well, to receive an indication by end of calendar year '24. We hope along the way we can publish some data, make it public. During that process, we think it will be compelling. If it's based upon other data that you know has been published around the globe by physicians who've utilized this unique device to treat these intermediate-risk prostate cancer patients, we believe the data is going to be compelling, not only because it reduces the effect of the tumor, but we also give the quality of life benefits back to those patients that they would risk with other procedures. So we're excited, Bill. We're going to again just continue what we're doing today, support our customers. But we would expect when we receive that indication, you'll see a different selling and marketing and clinical support approach from our company to maximize the opportunity in this market. That will really kick in more in calendar year '25 after that indication is received.

Thanks for taking my questions.

Thank you.

The next question is from the line of Matthew Mishan with KeyBanc Capital Markets. Please proceed with your question.

Thanks. Good morning. Thanks for taking the questions. Hey, Jim, Steve, it seems like you're taking a little bit of a different approach to guidance this year, especially around some of the individual moving pieces. But could you help us build up to that 20% to 25% Med Tech guidance for FY '24? What is, what's above, what's below, and how you're accounting for AngioVac in that?

Yes, it's a great question, Matt. Over the past couple of years, as we began reporting our business in the two segments—Med Tech and Med Device—we wanted to provide you with more detailed insights due to some new product launches. You've been able to observe the growth of our businesses. When considering the Med Tech guidance of 20% to 25% growth, you can see the progress with Auryon. We're pleased with what we're experiencing with Auryon and the opportunities to increase market share and utilization within our existing customer base. Auryon is on that same growth path. In terms of NanoKnife, we've seen over 20% growth in probes as we continue to execute our trials and strong performance in both the U.S. and international markets, which follows a similar growth trajectory as Auryon. Regarding thrombectomy, AlphaVac is in its second year since launch and is a growth product for us. We expect to see good growth from AlphaVac. When developing our models, we considered what we observed last year with AngioVac. We remain optimistic about AngioVac as it still has growth potential. However, as we mentioned in Q3, we are addressing the challenges we faced with AngioVac. Q4 showed sequential improvement, which indicates that we have likely reversed that trend. We factored this into our guidance and the modeling for Med Tech.

Okay. That's helpful. And is the way to think about the mechanical thrombectomy platform that you'll hopefully execute with the FDA and get a indication for pulmonary embolism at some point towards the end of this fiscal year, middle of next year? And at the same time, given it does seem like it's a 510(k) process, you potentially could launch in that same year a DVT product with Auryon. Is that the right way to think about a year out like FY '25 as pipeline?

Yes, Matt, your timeline is pretty accurate. We agree with your assessment of APEX PE, completing the study and possibly receiving an indication. We provided a rough estimate since there is still significant regulatory work ahead. However, your timeline aligns with ours. We anticipate having the APEX PE indication approximately a year from now. Then, about a year later, we discussed launching the Auryon version for venous thrombectomy in calendar year '25. The next 24 months will be exciting in that area: obtaining the PE indication for APEX is crucial, along with some design enhancements and developments in the next calendar year, followed by the launch of the Auryon version in '25. We are genuinely excited about how we will become a significant player in that market with a strong portfolio over these next 24 months.

Okay. And then on the Auryon international opportunity, just curious, is the model going to be different there, whether maybe capital purchases of the equipment, or is it still the same commercial model, where you take that on your balance sheet and it's really just the disposable volume?

Yes. Great question. Thanks for asking. We're seeing a different approach, Matt. It didn't have the amount of kind of history built by the other player in the market who had utilized the approach already providing capital to market. That was more prevalent in the U.S. So we're already seeing a different approach towards the European market. We'll give you more details as we get into the market. But I think the model you're talking about, capital being done differently is what we expect as well. So it won't require as much significant investment from us to bring new customers online.

Okay. That's great. Thank you.

Thank you, Matt.

Thank you. At this time, we've reached the end of question-and-answer session. I'll turn the call over to Jim Clemmer for closing remarks.

Thank you, operator, and thanks again to the team at AngioDynamics. Hope that the investors are seeing our commitment to our transformation as we're going to become a growth company that does provide profitability to the bottom line for years to come, based and founded by our innovation and the quality of our products. Thank you for joining us today. We'll speak again soon.

This concludes today's conference. You may disconnect your lines at this time. Thank you for your participation.
