[Andrew Hykes, executive]

Thank you all for joining our call today.

In Q3, we continue to drive strong adoption of our therapies, resulting in record revenue of $153.4 million and 21% year-over-year growth. Based on our year-to-date progress, we are pleased to raise our full year revenue guidance and reaffirm our expectations to reach sustained operating profitability in the first half of 2025.

Before proceeding, I'd like to formally welcome Kevin Strange, our new CFO, to today's call. With over 15 years of experience, including over 4 years here at Inari, Kevin brings tremendous expertise, judgment and leadership to our C-suite. He has also shown a steadfast commitment to our mission and patients. Additionally, I'd like to thank Mitch Hill for his contributions. As a reminder, Mitch will remain with Inari through early January as we continue the transition.

Turning back to our quarterly results. We drove strong performance across the entire Inari portfolio, including our market-leading PE and DVT therapies and in our emerging therapies portfolio. We also delivered robust growth in our international business. As we advance into the fourth quarter, we are as excited as ever about our leading position in large and underserved vascular markets. This is especially true as we await the presentation of PEERLESS data at the TCT Symposium tomorrow. We believe this presentation marks the beginning of a golden era of randomized controlled data focused on thrombectomy for patients suffering from VTE.

In Q3, our global VTE revenue was $145.3 million, up 19.7% versus the prior year, underpinned by our commercial expansion and market development efforts. During the quarter, we saw stable underlying market and share dynamics. The market for U.S. VTE procedures remain significantly underpenetrated, and as the market leader, we continue to expect to drive robust growth and adoption of mechanical thrombectomy for years to come. Our VTE-focused sales force, the largest in the industry, continues to mature as we hire reps in split territories and measured pace. The team is making progress in helping their hospital customers build VTE Excellence programs to help ensure that each patient diagnosed with the DVT or PE is giving consideration for interventional therapy. We are excited that a substantial opportunity remains ahead, and we look forward to continuing to drive higher adoption and penetration across our account base.

Turning to our clinical work. We are proud to usher in the golden era of randomized controlled trial data in VTE through the presentation of our pure-list data tomorrow. As a reminder, PEERLESS is the first of our 3 major RCTs to complete enrollment. PEERLESS was designed to evaluate patient outcomes using FlowTriever as compared to catheter-directed thrombolysis. As a reminder of the patient population addressed by the study, we believe the annual incidence of intermediate high PE is approximately 280,000 patients, all of whom are eligible for mechanical thrombectomy with FlowTriever. Of these patients, today, we believe, only 15% to 20% or about 50,000 patients annually receive any type of catheter-based intervention. We estimate that of those 50,000, about 1/3 or 15,000 patients are still being treated with [Indiscernible] thrombolytics.

Based on our AFPs, we, therefore, see roughly a $150 million opportunity to convert the remaining catheter-directed thrombolytic procedures to mechanical thrombectomy with FlowTriever. Of course, this is alongside the opportunity to continue to convert to 80% of patients still being treated by conservative medical management with anticoagulation alone. Should tomorrow's data be positive, over time, we would expect many more patients to receive mechanical thrombectomy treatment with our FlowTriever device due to its unique large-bore aspiration technology and blood return capability. Data from the trial will be presented at TCT by Dr. Wissam Jabber, Professor of Medicine at Emery University School of Medicine during late breaking clinical trial session at 11:44 a.m. Eastern Time tomorrow. I look forward to talking with many of you on site and hope many of you will also join us for our PEERLESS discussion happening at 2:00 p.m. Eastern Time tomorrow, following the late-breaking clinical trial session.

Beyond PEERLESS, we're making progress on enrollment in our 2 other currently active RCTs, both of which compare our products to conservative medical management, PEERLESS II, comparing FlowTriever anticoagulation alone in PE and Defiance, comparing ClotTriever to anticoagulation alone in DVT. We believe our investment in these studies will further advance the field change guidelines, extend our leadership position and ultimately change the standard of care in VTE away from conservative medical management to frontline treatment with FlowTriever and ClotTriever.

Turning to our Global Emerging Therapies business. In Q3, we delivered over $8 million in Emerging Therapies revenue, up 64% versus the prior year. We expect emerging therapies to deliver a strong finish to the year with several Q4 catalysts already in place and still others coming soon. Years of purposeful investment in this segment has led to the addition of 4 distinct patient populations outside of VTE, together comprising a $4 billion TAM in the U.S. alone. In our chronic venous disease portfolio, we continue to advance the adoption of VenaCore following our full market release earlier this year. As a reminder, physicians are using VenaCore and both the tool to treat CBD and in certain cases, to augment treatment and DBT. The addressable market in CBD includes an annual incidence of approximately 100,000 patients, representing a USD 1 billion TAM and a substantial prevalence pool of over 1 million patients. CLTI also remains an exciting opportunity for us. LimFlow offers new hope for the 55,000 patients per year suffering from no option CLTI, translating into a USD 1.5 billion TAM. I am pleased to report that our U.S. launch is progressing well. As we formally anniversary the addition of LimFlow to Inari, we're making great progress. As of the end of Q3, we have received that approvals in over 50 of the approximately 200 high-volume Lim Salvage Centers of Excellence that comprise our early launch target. We look forward to supporting initial procedures and growth over time across these and more centers.

In addition, we've been hard at work to iterate on the first-generation LimFlow system as is the Inari way. Earlier in the quarter, we received PMA approval from the FDA for our next-gen stent delivery system, and I'm happy to share that we are now in limited market release. We look forward to beginning the broad commercialization of this key component in 2025. Continuing with our work on LimFlow, I'm pleased to highlight that the NTAP proposed earlier this year for LimFlow procedures performed in the inpatient setting, went tuned into effect as planned at the beginning of October.

Thanks to the NTAP, reimbursement for inpatient procedures has now increased by as much as $16,250. Regarding outpatient procedures, as noted on our last call, in Q3, CMS proposed to increase hospital outpatient reimbursement for the LimFlow procedure from $27,500 to $35,000, a meaningful increase. This enhanced reimbursement is relevant to the roughly 20% of LimFlow cases currently performed in a hospital outpatient setting. We expect to see the final ruling from CMS for outpatient reimbursement in the next 2 months.

In acute limb ischemia, I'm pleased to share that we recently received 510(k) clearance for our next-gen Artix system and have commenced a limited market release. This product serves a $600 million U.S. TAM, characterized by tremendous unmet needs and a lack of purpose-built tools. Artix will not only address patients who would have been treated surgically but we believe this second generation improves upon other re-purposed endovascular platforms. We plan to commence a full market release later in Q4.

Our final emerging therapies market addresses the treatment of AV fistula clots using our InThrill device. Based on physician feedback, we're working on a second-generation intro platform, and we look forward to bringing that to market next year. As evidenced by the great progress made year-to-date, we are confident our Emerging Therapies business can 1 day account for at least 20% of Inari revenue.

Finally, I would like to discuss another record quarter in our international business. Revenue of $11.5 million was up 76.4% versus the prior year. Strength was primarily driven by adoption of our solutions in Europe. In Lat Am, we recently received regulatory approval for FlowTriever in Brazil and are in the early stages of our launch in that market. We're also making continued progress on our expansion efforts into both China and Japan. In China, we've been hard at work for 2 years to gain regulatory clearance for ClotTriever and FlowTriever. Of late, in conjunction with the National Medical Products Administration, we ran a 25-patient study for ClotTriever in China. We're excited that we've recently completed that study and have submitted the data to the NMPA. We're now finalizing our go-to-market strategy, and we'll have more to share about that by year-end.

Turning to Japan. We are pleased to announce we have obtained PMDA regulatory approval for our ClotTriever device and are seeking reimbursement approval later in Q4. Looking ahead, our next step in Japan will be in the form of a post-market study of approximately 100 patients supported by our recently established distribution agreement in Japan.

In conclusion, we're excited about the progress making internationally and expect total international sales with a one-day account for at least 20% of Inari revenue.

Before turning things over to Kevin, I'd like to highlight, as we always do, a patient story that demonstrates the impact of our technology and highlights the kind of patient that makes the PEERLESS study so relevant. A 58-year-old woman in Louisiana was admitted to our local hospital where she was determined to have an intermediate risk pulmonary embolism with large clot burden. For physicians were familiar only with the eco-thrombolytic procedure. Despite 11 hours of a linac infusion in the ICU, her improvement was only marginal. Given that she has completed the recommended treatment, she was discharged home with the [Indiscernible] recover on oral anti-coagulation. Unfortunately, that same evening, she was taken to a different hospital with persistent symptoms of trouble breathing and passing out. Her CT scan showed no change in clot from before. This hospital, with the assistance of Inari Medical, had developed a comprehensive PE thrombectomy program and had several physicians well versed in using the FlowTriever system. In a short 45-minute procedure, the patient had all of the acute and chronic thrombus removed from her lungs. The FlowSaver device was successfully used to safely return 600 ccs of the patient's own blood back to her. She was discharged home the following day and has since recovered completely. This case highlights the limitations of catheter-directed thrombolytic therapy, primarily incomplete thrombus resolution and ICU length of stay. The case also points to the need to educate more physicians about the benefits of FlowTriever, which include immediate symptom relief, rapid heart recovery and short length of stay. These benefits are directly attributable to the FlowTriever Systems unique mechanism of action, which offers both best-in-class thrombectomy and the safety of blood return. Our PEERLESS study will directly address the thousands of patients like this one.

With that, I will now turn the call over to Kevin.

[Kevin Strange, executive]

Thanks, Drew.

Turning to our third quarter 2024 results. Inari's revenue for the third quarter of 2024 was $153.4 million, up 21.4% over the same period of the prior year. This represents sequential growth of over $7.6 million. Global VTE revenue in the third quarter was $145.3 million, up 19.7% over the same period of the prior year. Global Emerging Therapies revenue in the third quarter was $8 million, up 64% over the same period of the prior year. International revenue of $11.5 million was up 76.4% compared to the prior year. Our best-in-class gross margin was 87.1% for the third quarter of 2024 compared to 88.5% in the prior year period. The year-over-year change was due to product mix, the ramp-up costs associated with new products and increasing internationalization of the business. Sequential gross margins improved by 80 basis points over Q2 2024.

Operating expenses were $147.1 million in the third quarter of 2024 compared with $109.8 million for the same period in the prior year. R&D expense was $29.4 million in the third quarter of 2024 compared with $21.5 million for the same period of 2023. The increase in R&D expenses was primarily due to a onetime noncash impairment charge associated with previously capitalized software development costs increases in personnel-related expenses, clinical and regulatory expenses. We anticipate R&D expense as a percentage of revenue to decrease sequentially in the final quarter of 2024 to a level similar to that of Q2.

G&A expense was $108.3 million in the third quarter of 2024 compared with $85.6 million for the same period of the prior year. The increase in SG&A expense was primarily due to increases in personnel-related expenses as a result of increased headcount and increased commissions share-based compensation, legal, marketing and other admin expenses. As anticipated, SG&A as a percent of revenue moderated closer to the level we saw in Q1. We anticipate SG&A expense as a percentage of revenue will further decrease in the final quarter of 2024. In the third quarter of 2024, the change in our fair value adjustment of our contingent consideration liability was $6.6 million as our LimFlow business continues its exciting progress. Amortization expense related to the acquired intangible asset was $2.5 million and acquisition-related expenses were $0.3 million.

In the third quarter of 2023, we had acquisition-related expenses of $2.1 million. Inari reported a GAAP operating loss of $13.6 million in the third quarter of 2024 compared with a GAAP operating income of $2.1 million for the same period in the prior year. On a non-GAAP basis, which excludes acquisition-related expenses, acquired intangible asset amortization, changes in the fair value of our contingent consideration and the environment of capitalized software and related costs. The third quarter operating loss was $0.4 million. The non-GAAP adjustment included $2.7 million related to acquisition-related expenses in the third quarter of 2023.

Net loss was $18.4 million for the third quarter of 2024 compared to a net income of $3.2 million for the same period of the prior year. The basic and fully diluted net loss per share for the third quarter of 2024 was $0.31 on a weighted average basic and diluted share count of $58.4 million. This compares with a basic and fully diluted net income per share of $0.06 and $0.05 on a weighted average basic and diluted share count of $57.4 million and $58.6 million, respectively, in the same period of the prior year. As we execute against our goals of driving strong growth and leverage within the business, we are also maintaining a thoughtful approach to managing our balance sheet.

In the third quarter of 2024, our cash flows provided by operating activities were $1.9 million. We look forward to driving improvement in this area going forward. At the end of the third quarter, we had a healthy balance of cash and investments totaling $111.6 million. We remain confident in our ability to self-fund our business and strategic objectives with our current cash and access to liquidity. We anticipate our cash balance will remain above $100 million for the duration of the year.

Turning to our 2024 outlook. We are raising our full year 2024 revenue guidance to $601.5 million to $604.5 million, an increase of $3.5 million at the midpoint of our prior guidance range, reflecting growth of 22% to 22.5% over 2023. Our guidance reflects contributions from all 3 of our pillars, DTE, Emerging Therapies and international.

Lastly, I would like to comment on Inari's progress its profitability. We are continuing to invest in our strategic objectives to drive growth while remaining fully committed to achieving sustained operating profitability. Looking ahead, we will continue to strengthen our profitability profile and feel very confident in delivering on our commitment to sustained GAAP operating profitability in the first half of 2025. We also anticipate roughly breakeven GAAP operating income in Q4 of this year.

With that, I'll turn the call back to the moderator for questions. For the Q&A segment, we will be joined by Dr. Tom Tu, Inari's Chief Medical Officer.

[Thomas Tu, executive]

We will now begin the question-and-answer session. If you're using a speaker phone, please pick up your handset before pressing the keys Again, we ask that you please limit yourself to 1 question and 1 follow-up on today's call.

At this time, we will take our first question, which will come from Kallum Titchmarsh with Morgan Stanley.

[Kallum Titchmarsh, analyst]

Just wanted to get your views on core VTE market health as we push into 2025. Right now, I think the Street is modeling US BT revenue growth in the low to mid-teens, which kind of lacks that 1% to 2% you've called out previously. So I would just appreciate any sense of how you're thinking about the core market next year and the moving parts we should keep in mind as we refine our models.

[Andrew Hykes, executive]

Yes. Thanks for the question, Ken. I can get started on that, and Kevin and Tom may want to join in as well. But I think you heard in the prepared remarks, our view in Q3 was that the market was stable with what we've seen earlier in the year. Stable underlying market dynamics, stable share dynamics as well. Our VTE business globally grew 20% in the quarter, a little faster than that. OUS a little slower than that here in the U.S. But suffice it to say, we see a long runway for continued robust growth within VTE. And we're going to keep investing in the areas that are going to drive that growth and purpose-built technology and high-quality data, including RCT data starting tomorrow morning of PEERLESS with continuing to invest in a commercial footprint and our market development efforts under VT excellence, all of that gives us confidence that there's a long runway here given how early we are, inflecting this market away from conservative medical management, mechanical thymectomy with FlowTriever and ClotTriever frontline.

[Thomas Tu, executive]

Great. And then just on inflow Obviously, you mentioned you've got the NTAP in play now. So what kind of uptick in procedure demand are you anticipating here? Or just any color on what you've seen so far in October would be really helpful. Because I think emerging therapies maybe missed our estimates slightly in Q3. So just appreciate any kind of sense of the growth algorithm for this part of the business as we exit the year and pushing 2025?

[Andrew Hykes, executive]

Yes. Thanks, Kallum. I can get start on that one as well. So inflow was an important part of the growth we saw in emerging therapies in Q3, it grew 60-some percent year-on-year. We did see some roughly flat sequential growth in emerging therapies, but Lim Flow within, emersion therapies did grow sequentially Q2 to Q3, we're coming up on a year anniversary with LimFlow and we are very pleased with the early commercial ramp. We had always viewed 2023 as 2024, rather, as you know, as a foundation-building year with LimFlow. I think that's largely the work we've accomplished. We've strengthened the supply chain. We've gotten the team aligned and organized. We, of course, have gotten NTAP and PC, both in place for enhanced reimbursement. NTAP, as you mentioned, went online October 1, and that will further enhance what was already a pretty attractive economic value proposition. So we're seeing nice growth with LimFlow month after month, quarter after quarter. And we anticipate that growth certainly to continue next year with the foundation that we've established here in '24. We're going to be able to leverage that foundation to really have a strong really first commercial year and 2025 with LimFlow and clearly the NTAP is going to provide a nice tailwind for those efforts.

[Adam Maeder, analyst]

And our next question will come from Marie Thibault with BTIG.

[Marie Thibault, analyst]

Congrats on a nice quarter. I wanted to ask here a little bit about what's assumed in your Q4 implied guidance this year. Certainly, your remarks to Kallum 2025 growth drivers. But I want to understand, could PEERLESS have an impact? Are any of these kind of new devices built in. What's kind of a thing in the Q4 guide?

[Kevin Strange, executive]

This is Kevin. I can jump in on that one. Look, I think overall, we feel good about the performance of the business growing 21.4%, and the overall strength of the busier heading into the end of the year, growing 22% year-to-date. We feel like the raise that we've agreed here throughout the year of $15 million at the midpoint really drives where we want to be, towards the end of the year. And that's really reflective of the confidence that we have in the business overall. There are obviously some moving pieces here that we've got headed into the end of the year with Artix just coming online now. So got PEERLESS that's going to be rolling out here shortly. And we've got LimFlow, of course, that's going to be online with the NTAP. But overall, I think the confidence here is reflected in the $3.5 million raise at the midpoint. And we feel good about the guidance raise here to 22% for the year.

[Marie Thibault, analyst]

Sure. Absolutely. That's really helpful, Kevin. Maybe my follow-up here on sort of the international market development. You have China and Japan coming online, hopefully, Certainly, it sounds like you've been doing well in several other countries. Can you talk a little bit about some of the catalysts we should watch for internationally in 2025?

[Kevin Strange, executive]

Yes. Thanks for that, Marie. I think as you look out in '25 with international, I think first and foremost, we're anticipating continued robust growth out of Western Europe. That region has been leading the way internationally. I would anticipate they will continue to do so in '25. We've got a nice footprint established in Europe. We've got enhanced reimbursement established in a number of European markets, Germany, for instance. I think all of that is going to continue to drive robust growth out of Europe in '25. Alongside that, I think in 2025, you're going to see more meaningful contributions from growth from the other international markets, and there's maybe 12 or 15 other markets across Asia Pacific and Latin America, where we've gotten regulatory clearance. We've gotten a commercial presence established, and we're now in a position to drive more meaningful growth. So I think you're going to see those markets contribute alongside European markets. And then finally, as you first talk about, we've been hard at work to get onto the market in both China and Japan. We're very close in both of those. You've heard some of the recent progress in China. We have completed a 25-patient study in market, which we've submitted to the LMTA. In Japan, we do have regulatory clearance now for ClotTriever and are finalizing reimbursement in Japan. So we've made some nice progress. And I think looking ahead to '25, I think both China and Japan will help contribute. We're going to have to ramp in those markets, just like you've seen us undertake in other markets. But I think, clearly, getting into those large Asian markets and begin to do the work we need to do will be another part of the growth in international next year.

[Operator]

And our next question will come from Dave Rescott with Baird.

[Richard Newitter, analyst]

I wanted to ask a little bit about maybe just your high-level thoughts about what you're thinking about PEERLESS. I know we'll give some better details on that pretty soon. But just wanted to think, should the results there bear out to be positive in the way that you're expecting what level of investment do you think you could put behind this to either sustain the growth you have, maybe try to pull some levers for modeling growth? How should we just start to think about that? And again, I appreciate we have more details when the results around.

[Thomas Tu, executive]

Yes. Thanks for the question, David. As you can tell, we're very excited to bring the peerless data to light. This is the first RCT in the pulmonary embolism space in about 10 years. So I think we're also excited to really raised the bar in terms of meaningful endpoints that patients and physicians and hospitals care about. As far as resourcing this, we anticipate a lot of marketing activity, not just intense around the time of the announcement, but also sustained because I think, as you heard in the prepared remarks, there's still a lot of unmet need. We think 1/3 of patients in the U.S. who get intervention for PE are getting CDC. And I think that is a large opportunity to improve patient care and also drive revenue.

[David Rescott, analyst]

Okay. And maybe on flow, heard some of the comments already there. I'm curious for the accounts that you're in. Maybe if you could give us a sense for I guess, fine relative to the goals you made earlier this year around the number of counts you go into, maybe where you stand today? And then for those accounts that you were already in, any color on what those accounts look like as it relates to monthly procedures, the reorder rates? Anything there would be helpful.

[Andrew Hykes, executive]

Sure, David. I can try and answer those. So you heard in the prepared remarks that we've now gained access to over 50 initial accounts, and that is part of that initial group of 20 million high-volume in click centers of excellence. So we've made some nice progress here out of the gate in 2024. We're probably a little ahead even of where we had expected to be at this point in terms of account opening. So we feel pretty good about the commercial ramp to date. We've got work to do from a market development standpoint. That is work we knew we were going to have to undertake and that's work we're actively chipping away as we speak. These are patients that are not cured for, in most cases, by interventionalists. These are patients that are being cared for in wound care, and it's a dietary and in some cases, even out in the community with GPs. So we've got work to do to help identify those patients and get them in front of a physician that can really assess whether that LimFlow is a new option for those patients. So that's work that we knew we would be focused on and sure enough that is exactly where our team is spending time understanding what that work looks like, what we need to do, what barriers we need to knock down. But suffice it to say, we like the progress we've made to date, tons of more work ahead of us. but so far so good in what we've seen today from a commercial standpoint.

[Operator]

And our next question will come from Chris Pasquale with Nephron Research.

[Christopher Pasquale, analyst]

A couple of questions on Artix. It's exciting to see that product back in the market. Just curious how you're going to position it in that segment relative to its strength versus competitive systems? And is there a particular subset of patients for whom that product is going to be a much better option than what's already able.

[Andrew Hykes, executive]

Yes. Thanks, Chris. I can maybe talk about some of the commercial aspects of it and then maybe Tom can chime in on the clinical part of your question. So we are a week or 2 into the LMR, we got 510(k) clearance, maybe it's just a week ago now. So still pretty early, but so far so good. We've got some really good feedback from the initial set of cases. As you recall, this has been a almost a 2-year journey to get back into the market with Arctic this next-gen platform. So we're really excited to be back in the market. We were very intentional to deliberate about the refinements we made to the platform and are hopeful that the second gen platform will help address what is a pretty significant unmet need for these patients. Over half of them are still being treated with open surgical approaches. And we believe that a [Indiscernible] 2 electronics going to be a better option for the patients that are currently being treated with other endovascular platforms. So still early, we need to get through the LMR as we always do. But so first is good, and it's exciting to be back in the market with Artix. Maybe with that, Tom can back clean up on some of the clinical parts of your question.

[Thomas Tu, executive]

Yes, Chris. So you asked about how we might position the strengths of Artix in the market. If you recall, the acute limb ischemia market is a mature market. The patients get treated. Unfortunately, the treatments that exist currently have significant limitations either because of open surgery or need for multiple interventions, the use of lytic. And frankly, the aspiration thrombectomy system that is used in a lot of procedures is inadequate for removing clot and results in distal embolization. We believe in Artix, we have a toolkit that's the all-in-one solution that you have the best-in-class mechanical thrombectomy best-in-class aspiration. And the results that we've seen, as Drew alluded to early on, but still fantastical results that just haven't been able to be achieved with the technology to date. So we can't wait to get more experience and then once we get through the early phases, then release it broadly across our customer base.

[William Plovanic, analyst]

That's really helpful. And then just on the core VT business, curious any differences in trends you're seeing between the 2 segments there, DVT versus PE. Our sense has been that the Ps is continuing to grow a bit faster. Just curious if you're seeing the same.

[Andrew Hykes, executive]

Yes, I think that's right, Chris. You heard in the prepared remarks, pretty stable trends we saw as we move through Q3. I think that's true within PE, I think that's true within DVT. And I think our view is exactly what you shared. I think at the margin, the PE segment of the market has been growing faster on a marginal basis than DVT. And I think that was a pretty consistent trend that we saw unfold in Q3.

[Operator]

Our next question will come from Stephanie Piazzola with Bank of America.

[Stephanie Piazzola, analyst]

I just wanted to follow up on PEERLESS. You called out the $150 million opportunity that the data could help open up. Maybe if you can elaborate a little bit more on how quickly this revenue opportunity could come through, or how quickly you expect doctors to change practice from the data if it's positive?

[Thomas Tu, executive]

Great. Thanks for the question, Stephanie. And like we said, we're very excited to bring this data to light tomorrow at the TCT meeting. Mind you, even with a highly successful trial, I think it takes time for physicians to really read and comprehend the results and then put those conclusions into practice. So I suspect what we'll see is the continued erosion of CDC market share and probably relegating that therapy to very niche uses, but I think the bulk of that transition is going to be a 2025

progress. And maybe just to follow up, I just wanted to clarify on the U.S. versus OUS performance in VTE. We estimate that the U.S. CDC market grew in the mid-teens, consistent with prior quarters. Is that a fair assumption? And is it still fair to assume that most of the OUS revenue is from VTE versus emerging therapies?

[Andrew Hykes, executive]

Yes. Thanks for that, Stephanie. So the overall growth globally for VTE in Q3 was 20%, a little bit faster than that. OUS a little bit slower than that here in the U.S. We don't break out specifically the U.S. versus OUS, but that at least gives you some context around the 2. And again, relatively stable trends in Q3 compared to what we've seen historically. And then finally, the last part of your question, yes, the vast majority of our revenue, OUS, is indeed from VTE, that will likely change over time as we work to bring some of our emerging therapies to the international markets. But today, at least, the vast majority of OUS is directly attributable to VTE.

And our next question will come from Larry Biegelsen with Wells Fargo.

[Lei Huang, analyst]

It's Lei calling in for Larry. Nice quarter. My first question at our health care conference last month, when you were asked about 2025, you talked about aspiring to be a 20% grower, and you're confident that will continue to be the company's target going forward. The question there is, are you confident that you can grow 20% in '25? Current consensus is closer to 18% growth? And I have a follow-up.

[Andrew Hykes, executive]

Yes. Thanks, Lei. So looking ahead to '25. We are very excited about the runway that we see for continued robust growth across all 3 parts of the business. Within VTE, of course, we're going to be able to continue to leverage PEERLESS, as you heard Tom describe, we've got new products coming in VTE next year, continued traction work with VT Excellence. Emerging therapies will be a big year for us next year with Artix and full market release with the first full year of LimFlow commercially. We've got a next-gen product something InThrill, continued traction with CBD. You heard me describe earlier the catalyst in international across Europe and Lat Am and Asia Pacific and some of the new markets coming online as well. So over the next 60 days, we will to call that into account. We'll have a chance to look at Artix in the first 60 days and PEERLESS in the first 60 days, all of that will inform our guidance that will roll out early next year. But to be clear, what remains unchanged is our commitment to continued premium robust growth. That will remain our top priority in '25. Alongside that, a second clear priority is going to be the work we're going to continue to do in path to profitability. And you heard Kevin describe some of the recent progress here even this year and our confidence looking ahead for that progress to continue. Last thing I'd point to relative to guidance next year is that philosophically, we will continue our historical approach. And we put a number out from a guidance perspective. We want to be highly confident in delivering on that number. And I think that's another part of our guidance that won't change looking ahead to next year.

[Lei Huang, analyst]

That's helpful. And just my follow-up on China and Japan. I didn't look your comments are related to ClotTriever. Is there an update on FlowTriever in those markets. And any additional color you can provide on the post-market study in Japan and the distribution agreement.

[Andrew Hykes, executive]

Sure. Thanks, Lei. So we've been working the last couple of years to gain regulatory and reimbursement approval in both China and Japan for both FlowTriever and ClotTriever. In both of those markets, for different reasons, ClotTriever has led the charge and is a step ahead of where we are at with FlowTriever. So as we enter those markets initially, we'll be doing so with ClotTriever initially. And then following that commercial effort will follow with FlowTriever to get regulatory reimbursement and commercial traction with the second product. The 25-patient study that I described, to be clear, was in China. That was a study that we conducted with ClotTriever end market in China with acute endpoints, we submitted data set to the NMPA and that data will be part of their final regulatory assessment for China approval. In Japan, as you heard us describe in the prepared remarks, we do have PMDA regulatory approval. We anticipate finalizing reimbursement approval here in Q4, and that will set the stage for us to do our initial work Japan should be in the context of a 100 patient post-market study, which is a requirement from a regulatory perspective. So that will be the initial commercial effort will be in the context of that 100 [Indiscernible] post-market study. Well, maybe last thing, I just answer the question on the distribution agreement. We did enter into a third-party distribution agreement in Japan for a partner to help us commercialize ClotTriever as it comes to market here. So that's another new update that we provided in the prepared remarks.

[Operator]

And our next question will come from Bill Plovanic with Canaccord Genuity.

[Unknown Analyst]

It's Jeffrey on the line for Bill. So it sells progressing really well in terms of both the reimbursement and back approvals. As we adjust our models today, what should we expect in terms of 2025.

[Andrew Hykes, executive]

So you heard us describe 2024 as a foundation-building year for LimFlow. That's really going to set the stage for us to drive meaningful growth out of LimFlow in 2025. And that is going to be built off the foundation of supply chain work that we've done this year, the NTAP, the team being aligned New Tech APC coming online, all those contributing to the growth. Within emerging therapies in '25, clearly, LimFlow is going to be an important part of the growth story with emerging therapies. I think Artix moving into SMR will be another key driver for us within emerging therapies. And then, of course, later in the year, we'll have a next-gen platform launching with InThrill. And along the way, as a backdrop, we'll continue to do the work with VenaCore and RevCor in chronic venous disease. So lots of nice [ cat ] shaping up in emerging therapies next year. And I think to tell that list is going to be the growth we're anticipating out of LimFlow.

[Operator]

And our next question will come from Michael Sarcone with Jefferies.

[Michael Sarcone, analyst]

I guess just a follow-up on PEERLESS. Assuming tomorrow, we see -- or it shows what you're expecting it to show good outcomes. Do you expect Inari will benefit entirely from that study? Or is there a potential for a class effect that could just lift mechanical from become more broadly?

[Thomas Tu, executive]

Thanks for your question, Mike. I don't think there's going to be a class effect attributable to Peerless because I think FlowTriever is in a class of its own. Remember, the PEERLESS study randomizes FlowTriever to cater directed thrombolysis, and when we're talking about the FlowTriever procedure, there's only 1 device that has the kind of efficacy for thrombectomy as well as the safety of blood return that is the FlowTriever system. So I think that the results, if positive, are going to be directly assigned to the flow Trever treatment arm. And frankly, if other companies want to try to gain benefits, they should do their own studies.

[Michael Sarcone, analyst]

Got it. And then just 1 last quick one. Can you just comment on any trends in pricing in the core U.S. VTE market?

[Andrew Hykes, executive]

So Michael, I think the trends in pricing, again, were stable in the year. We've described in the past that pricing is a modest tailwind for us. We take price or attempt to take price as contracts come up for renewal. That's certainly the case in Q3. And then the second tailwind that we derive from a pricing standpoint is the continued conversion of accounts onto our VTE PPP pricing program, which mathematically ends up creating a bit of a tailwind. So those are the dynamics we saw in Q3 and again, very consistent with what we have described in the past.

[Operator]

Our next question will come from Richard Newitter with Truist Securities.

[Richard Newitter, analyst]

This is Rich, so just 1, I guess, on the next-gen delete system. Can you talk a little bit about what the actual improvement is that can make you in share in that case?

[Andrew Hykes, executive]

So a little garble derm. I think you're asking about the next-gen Artix system and what attributes of it gives us confidence we're going to be able to take share. Do we get the question right?

[Richard Newitter, analyst]

That's right.

[Andrew Hykes, executive]

I think Tom can take that one.

[Thomas Tu, executive]

Yes. Thanks for the question. We are really excited to bring Artix back to market, as you've heard in comments already. If we rewind back 1.5 years to the first-generation Artix, what we recognized was that there was a great need for mechanical thrombectomy for the acute limb ischemia market and that obviates some of the shortcomings of both surgery analytics and other approaches. The Artix Gen-1 system was very safe, but we realized we could improve with some of the ease of use with how the components work together as well as to improve the thrombectomy results. And we believe with this new generation of Arctics, which has a protection scheme to reduce distal embolization, has an upgraded funnel as well as mechanical thrombectomy platform that we're going to really realize the promise of what this technology can bring.

[Richard Newitter, analyst]

And then I guess my next question is on the P&L. We're all trying to kind of calibrate our models there anything you would want to point out in terms of the past to sustain operating profitability. It looks like R&D is signal pretty big step down this year, but the street hasn't stepping back up next year. Just hoping you give some color on puts and take should we be thinking about where the profit drivers are coming from for next year?

[Kevin Strange, executive]

Yes. Thanks for the question. This is Kevin again. So overall, look, I think we feel good about the progress that we're making on the operating income line. In Q3, you saw a $9 million sequential improvement on a GAAP basis from Q2. Excluding the onetime impairment charge that we talked about, it would have been closer to $13 million sequential improvement. We saw a nice improvement on the SG&A line and general stability on the R&D line. As we talked about on the last call, SG&A, we expect to step down to a more normalized level like Q1, and it did this quarter in Q3. So we're really pleased with that. And R&D, excluding the onetime charge, was roughly in line with Q2. So looking ahead, as we discussed in the script, we do see continue to step down in Q4 relative to Q3. And we'd expect general stability, if not a bit of improvement on the R&D line as well. Overall, that [Indiscernible] in lands area that's roughly breakeven from an operating margin perspective in Q4, which we're very pleased with. And we think we're well on our way to driving incremental operating leverage into the first half of 2025. And as you heard again the script, we remain fully committed to driving to sustain GAAP operating profitability in the first half of 2025.

[Operator]

Our next question here will come from Matthew Blackman with Stifel.

[Unknown Analyst]

Great. Can you hear me okay?

[Andrew Hykes, executive]

Yes.

[Unknown Analyst]

I've got 2 -- and Drew, on Peerless, I think the quote from the prepared remarks is that if we get positive readout we'll see CDT conversion. So I guess that bags the question, what you think constitutes a positive readout, if you're willing to share? And then 1 follow-up.

[Andrew Hykes, executive]

Sure. Thanks for that, Matt. So this study was purposely designed with meaningful clinical endpoints as the win-loss ratio composition that's exactly what physicians have been asking for. We have moved past the era where surrogate endpoints really are going to inform clinical decision-making. As a result, if you look at the components of the win-loss ratio, each of them are important for clinical decision-making. Each of them reflect important outcomes for patients. That's the design of the study, and that's what you're going to see presented tomorrow in the late breaker tomorrow morning. The opportunity for us, if it is positive, is meaningful. As you heard Tom describe, 180,000 patients, we believe 150 of those are still today being treated with catheter direct to thrombolytics. That's exactly the readout that PEERLESS is going to shine a light on. So we're very excited to get the data out tomorrow morning. This has been a 3-year journey to get to this point. So excited to be on the eve of that readout tomorrow morning.

[Unknown Analyst]

Understood. And then just on VT Excellence, just where are you in terms of accounts across the 3 phases of the program. Just remind us of the trigger points would be to move from 1 phase to the next. And how long that transition often takes and whether that transition period is moving faster recently? Or just any color on an update on the VTE excellence program.

[Andrew Hykes, executive]

Sure, Matt. I can put a little more color on that. So recall that our view is all 1,700 of our accounts are in some phase of of a journey towards emerging as a VTE center of excellence. The vast majority of our accounts are in the earliest phase of our program, what we call Engage. In that phase, the work is focused on spreading awareness, on establishing a solid foundation, on ensuring that the interventionalists are getting solid outcomes in our first set of cases. We did some work in the first phase to ensure that the coding and billing is being done correctly and that the hospital is receiving credit for the work that they're doing from a reimbursement standpoint. All that characterizes the kind of work we do in Engage. And still today, the vast majority of our accounts are still in that phase. The penetration of the TAM in that phase is in the low single digits, just get started in laying the foundation. From there, we have accounts graduate into the second phase, what we call Empower. And in this stage, we're really focused not only on broadening awareness amongst the interventionalists, but also amongst all of the non-interventional stakeholders health care for these patients. So we're going to see room physicians, the hospitalists, the pulmonologists, the hematologists, all of the other caregivers. We spent a lot of time in Empower engaging and raising awareness among that group of caregivers. We also spend time focused on the administrators in the Empower phase to ensure that they appreciate not only the clinical benefits of FlowTriever and ClotTriever, but also the economic value proposition that goes along with our therapies. And as a result, they're supportive of the program building effort and investing into the program building effort. We've got a couple of hundred accounts in that in power phase and the TAM penetration in that phase is in the double-digit range. And then the final phase from there is a group of accounts that have graduated on to what we call Excel, and these are accounts that are beginning to perform as True ETE centers of excellence. They've got well-defined care pathways and algorithms. Many of them have a dedicated VTE coordinator in place. Many of them are in advantage of artificial intelligence-based diagnostic programs to ensure that patients are flagged. All of those are hallmarks of our most advanced group of accounts. We've got several dozen accounts in that phase. And the TAM penetration in that group is north of 20%. We've got several that are north of 50%. So it gives us some confidence we're moving in the right direction. Every account moves along that journey at its on pace. There's really no there's a lot of variability in the pace at which they move along that journey. But the important thing is we in progress. And as we make progress, we're driving deeper and deeper penetration and impacting more and more patients.

[Operator]

That is all the time we have for questions today. We will now conclude our question-and-answer session in addition to the call. Thank you all very much for attending and participating in today's conference. You may now all disconnect your lines, and have a great day.

[Andrew Hykes, executive]

Thanks, everybody. Take care.
