Exagen Inc. Price & Performance (XGN)

Descriptions of these non GAAP financial measures and reconciliations of GAAP to non GAAP financial measures are included in today's press release. [indiscernible] I'll now turn the call over to John. Good morning, and thanks to everyone for being on the call today. I'll start off by recapping our results from 2024 give some color from the launch of our new markers and comment on our outlook for 2025. Jeff will provide additional detail on the financials later in the call. 2024 was a great year at Exagen. We made major strides in continuing to build the leadership team, needed to elevate our organization to the next wave of growth And we've made significant progress in executing on our strategy towards profitability. From a top line perspective, we've delivered another year of record total revenue. Growing to $55,600,000 driven largely by continued improvement in reimbursement. With this progress, our adjusted EBITDA loss narrowed to approximately $10,000,000 showcasing our focus and prudently operating our business. Our trailing twelve month average selling price increased to $411 for Advise CTD, a gain of $75 per test over 2023. As a result of our ASP gains, and continued excellent operational management, gross margins expanded just over 300 basis points in 2024 compared to the year prior.

Coming in close to the 60% mark for the full year.

Perhaps most importantly, we developed and commercialized new biomarkers for the first major enhancements to advise CTD since the product's inception. We also finished the year with an incredible achievement testing our one millionth patient by Bio CTD and are extremely proud of the many milestones our organization reached in 2024. To dive deeper into the launch of our new biomarkers this past January, I'm very proud of the hard work and preparation exhibited by our operational and commercial teams. These efforts have resulted in a successful launch to the rheumatology community. The markers have been well received by our ordering physicians and we are encouraged by the early signs we're seeing We've already started to see an impact on patient care. With the utilization of the new markers. And while we're working diligently to educate clinicians on the value we've demonstrated through our clinical studies, it doesn't truly start to resonate with folks until they have a positive firsthand experience themselves. To share an initial example of what we've heard already, in Florida, one of the rheumatologists who leverages Advise received a new patient with a prior diagnosis of fibromyalgia.

Typically a diagnosis of exclusion. There were no serological abnormalities and the patient was being treated for pain management. The patient was not responding to therapy and given that it was a new patient, the clinician decided to run our enhanced CTD panel their own evaluation. The entire profile came back negative except for two of our new RA markers. Which were abnormally high. The patient's diagnosis has since been changed to that of rheumatoid arthritis, and they've started first line methotrexate therapy. This is a great example and case study of the impact we hope to have in the field. Obviously, the clinician is excited because this was a challenging patient who was refractory to treatment. And the clinical presentation of the patient had similarities to RA but lacked biomarker confirmation. Now they have serological evidence to support a diagnosis. And can proceed confidently with a treatment decision Finally, this specific type of serological presentation tends to So this has a higher likelihood of turning out positive for the patient long term than the track they were on because the diagnosis was reached sooner. Hopefully avoiding severe joint erosion and points them to a specific therapy. Again, this is a great case study We have several of these on the RA side which have come in.

So it's very exciting to see the initial results here. Overall, the feedback has been heavily weighted towards the RA impact but we are also hearing positive things on the lupuside with our new T cell markers. Physicians are still learning exactly what these markers mean, especially in the context of an otherwise negative advice profile. But luckily, our manuscript detailing the unique additional benefit of T cell analytes was accepted and published in a high impact journal Frontiers in Immunology, less than two weeks ago. We really believe that our publication marks a significant step towards establishing T cell biomarkers as a powerful tool for SLE diagnosis. As the publication details their superior and unique performance compared to conventional providing significant validation of our work within the rheumatology community. Their collaboration not only strengthens the scientific foundation of our findings, but also reinforces the broader clinical relevance of our assays in lupus diagnosis and disease management. This will be an essential tool in our educational campaign over the coming quarters. At this point in the launch, it's still too early to provide a precise indication as to the full financial impact the markers will have. But we are seeing approximately $90 per Advise CTD test in incremental revenue.

And it could grow from here as we continue to gather details on our appeal success rate. The $90 value is assumed for our Q1 guidance. And we'll have a more confident number as additional data come in by our Q1 call. Where we plan to provide an extended outlook for 2025. In short, and just to as it is truly a marquee accomplishment from the efforts last year. The additions of our T cell and RA33 biomarker biomarkers to our advised profile are catalysts on several fronts.

First, they were developed and intended to have a significant positive impact on patient care. And we are already seeing signs of that through clinical adoption and case studies. Second, they widened the gap on the clinical differentiation and Exogen offers over our competition. We already have the lead in novel proprietary testing for best in class connective tissue diagnosis. Third, our RA biomarkers open up a population of patients and clinicians that to date we have not meaningfully addressed which could represent a market opportunity that is anticipated to be larger than our existing lupus market. [indiscernible] Fourth, [indiscernible] these product launches validate our ability to focus, prioritize and execute on R and D pipeline initiatives that have a high impact The addition of these biomarkers and I look forward to continuing to share the full impact these markers have on patients and our company along with additional progress from our pipeline in the future. With the momentum we had to start the year, we're very excited about what's ahead in 2025. We continue to expect strong revenue growth driven by both ASP expansion and volume, And on that note, our performance relative to testing volume in 2024 did not meet our expectations.

And has been an area of heightened focus since the changes we implemented in 2023 to prioritize profitable volume. Again, some of this volume decline was expected and deliberate, as we have prioritized profitable growth but we have to do better this year we're off to a good start with the launch of these new markers. As our ASP increases, the profitability of our sales territories also increase. Which opens the door for expansion. We are currently operating at 40 sales territories, and anticipate adding a handful of new territories during 2025, in a measured fashion to continue to accelerate the utilization of Advise in clinical practice. Taking a step back at the end of the year, to reflect on our transformation these past thirty months. I'm incredibly proud of what this team has been able to accomplish. It is not common to reduce losses by 70 plus percent driven mostly by reductions to OpEx and still grow our top line. Our 40% or more gains to AS over the past two years are uncommon within this industry. And while we've demonstrated this type of [indiscernible] we've dramatically improved the company culture, reducing voluntary turnover by more than two thirds of what it was when I came to the organization.

People are better aligned to our overall goals, They understand the critical aims we need to accomplish and as we've made progress, it's fueled the motivation within the company's walls for the next horizon. Specifically, I'm incredibly proud of our R and D and CLIA teams for their development of these new new assays. Achieving the regulatory approvals and the commercial launch we undertook to start the year. As business partners, rest assured that you have a strong leadership team which is focused on creating long term value. And we started to really generate momentum. We believe 2025 will be a step function for our growth and I fully anticipate finding more opportunistic and creative ways to serve our existing customers while expanding our customer base in the future. I'll now turn it over to Jeff for details on our financial results.

Thank you, John, and good morning, everybody. As John mentioned, 2024 was a great year for the organization on several fronts. The team did a great job of executing and exceeding our goals for the year. We've set records for several of our financial metrics and have a clear line of sight to Diving into the details, starting with revenue, our full year revenue reached a record $55,600,000 marking a 6% increase from 2023. And this full year year over year increase in revenue was due primarily to expansion in ASP, consistent with our strategy of driving profitable revenue. As John mentioned, our trailing twelve month ASG for 2024 was $411 up $75 in 2024 and up hundred and $26 since 2022. [indiscernible] when John initiated a strategy to focus on reimbursement. We've continued to prioritize improvements in our revised CT average selling price through optimizing revenue cycle management. With much success but sometimes at the expense of volume growth, which was intentional, As a result, we saw an expected decline in volume due to attrition from doctors, who are unable to support the necessary partnership including additional documentation offer required for acceptable reimbursement levels. We also over the same two year period made the strategic decision to reduce our commercial footprint from over 60 sales territories at the end of twenty twenty two to roughly 40 at the end of twenty twenty four, eliminating several unprofitable sales channels.

This two resulted in an expected decline in volume. [indiscernible] Moving forward, we continue to prioritize ASV expansion, but expect to see a return to volume growth attributed to increased adoption from the enhanced utility provided for BioCT biomarkers and the addition of commercial territories with a focus on growing profit represents the long term trajectory of the business. Keep in mind, that we continue to grow revenue and expand gross margins while simultaneously significantly lowering our overall which is a great setup as we enter a period of expected volume growth continued ASP improvements and a shift to positive adjusted EBITDA and free cash flow. Moving to operating performance, gross margin was just under 60% in 2024. Compared to 56% in 2023. And the growth in gross margin was mainly attributed to increases in ASD. Gross margin was about 62% for the fourth quarter compared to 59% for the fourth quarter of twenty twenty three we expect gross margin will continue to which are accretive to margins and by continuing to streamline workflows in the lab. Over time, we believe we can expand gross margins well into the mid-sixty percent range. Turning to expenses, our operating expenses in 2024 were $46,700,000 down $5,500,000 or 10.5% from 2023.

Fourth quarter OpEx was 11,900,000.0 down from $13,300,000 in the fourth quarter of 'twenty three.

Breaking out our full year OpEx, of the $46,700,000 in 2024 about $41,000,000 came from SG and A, which was a decrease of thirteen percent twenty twenty three We Looking at SG and A composition for 2024, excluding non cash stock compensation sales and marketing was roughly flat while G and A was down over 17% as we prioritize our spend on growth initiatives. R and D accounted for $5,400,000 of the $46,700,000 in OpEx in 2024, and excluding stock based compensation, R and D was up 12% mainly due to the ramp up for the launch of our new markers. Our team has done a great job of controlling expenses and it's remarkable to see a decrease in operating expenses during a time when we added approximately 25 people to headcount. And continued to face inflationary headwinds. We've been able to reduce overall OpEx while continuing to maintain focused investments in our commercial organization and our R and D pipeline to support sustained long term revenue growth. And we will continue to manage this balance thoughtfully. With that said, we continue to see improvements on the bottom line with the adjusted EBITDA loss coming in at $10,100,000 for 2024 an improvement of 40% over 2023.

As a reminder, our adjusted EBITDA excludes stock comp expense and it's a non cash expense Please refer to our earnings release issued earlier today for a reconciliation of adjusted EBITDA to net loss. In 2025, as we continue to control expenses and expand ASP in revenue, we anticipate being adjusted EBITDA positive [indiscernible] fourth quarter of twenty twenty five which will mark a key milestone in the organization's turnaround. Turning to cash flow and the balance sheet. We ended 2024 with cash, cash equivalents and restricted cash of $22,200,000 representing a net neutral cash burn for the fourth quarter. Our accounts receivable balance at the end of twenty twenty four was just under $8,000,000 In 2025, as in previous years, we will begin the year by holding most claims. In line with our strategy to maximize our revenue cycle This will lead to an increase in AR and subsequent higher cash used as seen in previous years, but will normalize over the back half of the year. We believe our balance sheet today gives us the runway we need to take our business to sustain free cash flow positivity for the full year 2026 and beyond, and remain committed to creating and preserving long term value for our shareholders.

In regard to 2025 guidance, we are providing total revenue guidance of at least $14,500,000 for the first quarter And as mentioned earlier, we're on track to deliver positive adjusted EBITDA in the fourth quarter. We plan to share our full year 2025 financial outlook with the release of our first quarter twenty twenty five financial results. We'll now open the call up for questions.

Thank you. The floor is now open for questions. Today's first question is coming from Kyle Miksen of Canaccord Genuity. Please go ahead.

Guys. Thanks for the questions. Congrats on the year. Could you I know, John, you were talking about like you can't really quantify the impact the new markers just yet. Any way to help us think about maybe the modeling for ASU going forward based on these new markers, how that could trend this year? And then I think importantly, what the gross margin impact to from those like $90 I think, gross revenue you're talking about too. If you could just highlight those factors would be Thanks.

Hey, Kyle. Good morning. Appreciate the question. Thanks for the chance to expand.

So as it relates to the trend for the new marker reimbursement, the $90 specifically, The reason we're unable to exactly give the clarity for full 2025 right now is because we've been efficient and effective in our appeals process over time. It just takes a little bit of time for that to bear out. So the $90 right now is based on current cash collections plus some assumption for efficacy in our appeals process or revenue cycle. Process. And I think it's a pretty good approximation for right now. So, where that could trend, think similarly to what you're seeing with our broader business is we're effective and efficient in our ability to drive ASP gains. So it could likely trend up. It's not going to reach the $200 mark, I think that's unreasonable. It's not going to double. But it could creep up from there. We'll know more in our Q1 call. So maybe a month and a half, two months from now. As more of the appeal efforts come in. But it's a more straightforward billing process. And so think it's a pretty reasonable approximation.

As it relates to gross margin, your question was more broadly, what's the base business? Trending over time? Is that right, Kyle?

Yes. And I think the impact from the markers would be good to know as well given that's an ASP lift, so that you would think that the margin is better if the same, if not better, so it could help company gross margin, yes?

Got it. So we believe now it's addition of these new markers, the mid-60s is not an unreasonable expectation for margins over time. And so we'll have to see. I don't anticipate guiding necessarily, on margins, but that mid-sixty level is within reach. Awesome. And then Jeff, maybe one for you on the adjusted EBITDA profitability target for 4Q, that's great to see. Do you also have like an operating cash flow positive or breakeven target as well for 4Q? And maybe you could talk about that as well as the accounts receivable movement you expect throughout the year as well?

Yes, Kyle, great. Thanks for the question. Yes, I think as you think about on a full year basis, in our business, adjusted EBITDA is a good proxy for free cash flow and we spent a a full year basis. Nuance being that the quarter to quarter working capital impact of holding claims particularly in the first quarter, will increase cash requirements early in any year. But over the course of the year on a blended basis, I think thinking about adjusted EBITDA and free cash flow as a proxy for one another is right way to think about it.

Great. And last one for you, John, on actually the kind of want to ask your update on [indiscernible] kind of your thoughts to offer test or test data to biopharma companies. Like there's been a lot of news flow even in the past few weeks kind of regarding SLE drugs and so forth. Is there an opportunity there for you a partner to pharma given your industry leading position?

We believe there is. Our efforts on the biopharma side were really early when I joined the organization. Think we necessarily the business model was more capitalizing on inbound inquiries as opposed to having a selling process and cultivating partners that had some strategic impact. And where we thought we could provide a unique service or solution That has shifted since I've been on board. And as I detailed in 2024, we're pretty excited about some of the contract changes we've seen along with the magnitude of some of those contracts. The revenue from that comes in over a couple of year period. Should start to see more of that here in 'twenty five and very positive from our standpoint. There's some exciting development We do think that there's a tailwind in terms of the market. Growth there, spending on the autoimmune side from a biopharma standpoint is projected to increase over time. So it's a healthy area for investment. We're looking to capitalize on it we do have unique proprietary offerings. We have a group of right now about four individuals that this is really the area they focus on. So more to come throughout the year. I think you'll start to see some of the efforts we're putting in place and it'll be exciting to give you guys some updates.

But it's definitely a positive area for us.

Yes. Sounds promising. Thanks guys. Appreciate it. Thanks Kyle.

Thank you. The next question is coming from Ross Osborne of Cantor Fitzgerald. Please go ahead.

Hi, good morning and congrats on the progress. Starting off, would you remind us on where the January launch of RA33 will get you in terms of sensitivity and if there are any incremental improvements we should be thinking about this year? Yes. Hey, Ross. Good morning. Thanks for the opportunity to talk clinically.

So our January launch encompassed a set of two additional aspects to our test. The first being launch of novel T cell biomarkers which specifically improves the sensitivity for lupus diagnosis. And we just actually published our manuscript in Frontiers in Immunology pretty exciting publication very strong KOL support. And what that manuscript showed was for the lupus patients that were serologically negative, so their diagnosis was based solely on clinical aspects alone, The novel T cell markers, the three of which we launched, were positive in roughly fifty one percent of those patients. So way to think about this is obviously cohort to cohort, you have different variables and and whatnot. But a good way to think about this is we captured roughly half of the lupus patients that were not captured by conventional markers or our traditional advice testing.

So So ultimately that boosts sensitivity in our mind closer to about we're capturing nine out of 10 lupus patients through our entire advice test. Which is an exciting development for us. On the rheumatoid arthritis side, what we launched there were the first set of some novel biomarkers improving the sense [indiscernible] Specifically within the traditionally seronegative population. And from a rheumatoid arthritis standpoint, there's some fantastic biomarkers that exist, rheumatoid factor, [indiscernible] But about thirty percent of patients have no serological abnormalities. So their diagnosis is purely clinical. Very similar to what I just described on the lupus side. In that context, this first set of markers captures about fifteen percent, sixteen percent of those patients We have a second set of markers coming later this year hopefully by the end of the year. That will boost that overall to about thirty percent, forty percent. So in general, we believe that within the next, call it twelve months or so, we should be able to capture almost half of the seronegative population and that by far outpaces any other diagnostic that is commercially available. So very excited about both of those aspects. Great. Glad to hear it.

And then where does manufacturing stand in terms of capacity and how you feel about your ability to meet demand this year? That's a great question, So we invested heavily from a capacity standpoint towards the end of the year in any capital equipment we needed. Our more complex technology is flow cytometry. We did entire upgrade of our suite of of instruments in the back half of 'twenty four. That was about a $1,200,000 investment. That's all been made. We have significant investment in robotics that we've made over the last six months and we'll continue to do so here into 2025. Personnel wise, we've staffed up for the increased volume. That we expect and have started to see here in 2025.

So current capacity is adequate for the launch. We expect to scale with labor basically. And capital wise, we feel like we're in a pretty good shape at least for '5 and into '26. Our facilities have the capacity significant more capacity than the current testing volume. And what I mean by that is, we operate mostly primarily a day shift starts about four in the morning, goes to about eight at night. That's a day shift for us. And but can also go into the evening. And so we could have a night shift if need be to preserve the viability. To increase our capacity. And and it wouldn't require change from a capital standpoint or facility standpoint. So have some buffer there. Thanks for taking our questions and congrats again on the progress. Thanks, Ross.

Thank you. The next question is coming from Mark Massaro of BTIG.

Hey, guys. Thank you for taking the questions. John, the first one is for you. I thought the case study you provided in the prepared remarks was pretty interesting. In that the patient's diagnosis was changed from fibromyalgia to rheumatoid arthritis. With that case study and it sounds like you had a few others come in that were similar Are you now thinking that potentially the Advise product might have a larger total addressable market to rule in RA versus lupus? Or how should we think about the market size for the core product?

Yes.

Good morning, Mark.

A pretty interesting case study because it came to us unsolicited by the way. That clinician was super excited about their firsthand experience and it's always nice to get that feedback. We've had it happen in a few other places. And I was actually in the field last week talking to a group of physicians and it's very clear that they're enamored and interested in the about these new markers. And see the applicability to their clinical practice. So exciting when you actually get to see it firsthand in that sense. As it relates to your question, what do we think the market opportunity is and how has it shifted with the launch of these new markers? I do believe, I mean, I think it's pretty rational thought here that as you enhance your value proposition on the RA side, the utility for clinicians in that context increases. And that's what we believe currently and I [indiscernible] from our standpoint, rheumatoid arthritis prevalence is depending on your sources somewhere around eight times that of systemic lupus. So a dramatically different sized market We We do believe that the differential broadens the utility of the differential diagnosis broadens when we added these additional RA markers and we'll continue to do so throughout the year as we add additional waves to this.

So we're seeing it firsthand. With case studies. We're seeing it in some of the ordering. And that's a part of what's factoring into our sales expansion later this year as well for each [indiscernible] The potential basically has shifted in our minds. And so dramatically different market.

Okay, that's great. And then just to clarify, so obviously a $90 per test and incremental [indiscernible] you came in at foureleven for ASPs at Q4 and year end. Just making sure I'm hearing that you're feeling pretty good about getting the ASP per test to approximately $500 per test at Q1. And then just to clarify, do you think the $500 per test in Q1 if that's true, can serve as as a potential launching point for the rest of the year?

Very important point. Mark. Thanks for the chance to expand. So a couple of factors here. One, we launched the test part way into the quarter. So if you assume an average 500 per test, I think you're going to over overestimate for Q1 just given the sense that we launched, call it, the January. For the new markers. Additionally, and I just want folks to have clarity here, the trailing twelve month number will go up by roughly a little less than a quarter of that 90 we would anticipate over the coming quarters. And that's just because it's a trailing twelve month number. It incorporates data from the last four quarters so you're diluting out that 90 if you've only been a quarter in, for example. So just so that folks understand as we report out future numbers, some context there. But basically, Mark, your math is is pretty good, if you can take those two factors into account. And we believe that the incremental add is real $90 One other point that Jeff just made important to consider We do have prior period collections in any given quarter. And so the fluctuations that four eleven includes, I think about $2,800,000 in collections greater than twelve months from prior to 2024.

For example. So that's just something that we've said in the past, very difficult to forecast.

And can be lumpy. Just those three considerations just to put a finer point on that just so people understand. Clearly, the company and with John coming in and implementing this revenue cycle reimbursement strategy to expand ASP has met with great success. But we continue to raise the bar on ourselves because as we in enhance prior period collections, it increases our organic ASP and therefore our accrual rate. So some of that prior period collection now going forward is already baked into the to the average ASP. So there could be a bit of a tailwind on the average twelve months just because we're continuing to raise the bar in ourselves with the prior collections. Does that make sense?

Yes, it does. Thanks guys for clarifying that. That makes perfect sense.

One last question. You guys talked about in 2024, you saw some decline in volume due to attrition from docs. Who are unable to support or provide additional documentation required. To obtain reimbursement. I'm wondering if you think that you could go back to those physicians and walk them through the documentation needed because I'm wondering if you think that business could come back or not? And then is there any way that you could frame like what how much of the volume you think occurred because of that?

Yes, great question. So maybe some additional information that could be useful, Mark. If you take a look at the average number of unique ordering providers per quarter, in 2024, it was just under 2,500. So 2,500 unique ordering physicians ordered the Advise CTD platform per quarter on average in '24. Excuse me, in '23. In '24, it's about 2,400 So we lost about 4.5% of our ordering base year over year. Keep in mind, that if you take a look at the expense profile of that, we've gone an SG and A standpoint really reduced our overall SG and A by about $11,000,000 or $12,000,000 during that period as well. So from our standpoint, we're operating more efficiently. We've cut back the sales team. By a third when I joined. We're on the cusp of expanding as you told me at the start that you'd lose roughly about 4.5% of the physician base but still be able to grow your top line I would take that. Was really the intention of what we were trying to do. I do think that that business is recoverable. To your point.

We need to optimize our processes, so that prior auth becomes easier requesting medical records becomes less frictional It's just a smooth interaction in that sense. But I knew that if we continued on the path we were on, we absolutely were not going to get paid. And so there is a trade off there that has to occur Our value proposition continues to strengthen. With these new markers going back to those docs, they've already bought into these at Vyse at some point. In their clinical practice. And so this is really just smoothing out those interactions over time. That's where we've been heavily focused. So we'll continue to do that. But these new markets provide the perfect opportunity to go back.

All right. I'll keep it there. Thanks guys. Thanks, Mark.

Thank you. The next question is coming from Dan Brennan of TD Cowen. Please go ahead.

Great. Thank you. Thanks for the questions. Congrats on the quarter. Maybe just starting on pricing, can you just remind us in terms of your initial feedback from commercial payers? I think you're I think the last update you said, what, maybe less than 50% of commercial payers. Either you're getting paid or in contract. Just give us a sense what the new markers and that $90 lift that's kind of flowing through between your different payer groups?

Yes.

Good morning, Dan. Thanks for the question. From individual payer perspective, we think about it oftentimes in terms of financial categories. So we lump the Blues together, for example. We have some of the large national payers together. Government, etcetera. We're seeing very consistent performance as we have with some of our other traditional testing, Obviously, with these new markers, we're facing much lower rate of denial for experimental investigational reasons, for example. So there's not a lot of question to the utility of these markers within this disease context. What we are typically getting denied for, if you will, or where patient responsibility seems to be outsized is around in network status for the most part. And so that's consistent with again, some of our therapeutic monitoring testing that we offer and some of the financial modeling we did ahead of time. But relative to Advise CTD, lower rate of overall denials from a coverage standpoint, just your more typical out of network type denials, which is not a problem for us. If you think about it, out of network really is applicable when you offer something that someone else can do as well.

And in both of these settings, we're a sole source provider. So that's the basis for an effective appeal that you can't get these markers anywhere else.

Again, we'll know over time how effective we are in shifting some of the responsibility back from the patient to the payer. Basically being treated as in network status given the uniqueness of the markers, but that will take a little bit of time. And that will hone our precision on the $90 we gave.

Okay. That sounds good. And then on RA opportunity, just remind us and when you've sized or you think about the opportunity for the TestNow really to penetrate RA? Just what's kind of how big is that opportunity? How do we think about just even framing that over the next kind of year or two?

Yes. So, if ICTD is useful when you have a suspected connective tissue disease. And that number is not in the literature anywhere that we can find. So we triangulated our internal taking a look at incidents for each of these diseases along with the positivity rates we have on our advised test. And what we've been able to conclude is now with more confidence that the RA market is truly an opportunity for us with the unique offering, that the annual rate of connective tissue disease evaluations is somewhere around $2,500,000 So that would put us on a conservative side around five percent penetrated. If you want to create a range here with confidence intervals and whatnot, you can get up to maybe about ten percent penetrated. So just think the value proposition has been enhanced. We always had markers for traditional rheumatoid arthritis evaluation, but now there's a unique reason and opportunity for us to help patients and clinicians in this area. So that's really what we're going after. Somewhere around 2,500,000 tests a year is what our current estimate is.

Maybe if I can just go on the volume side. You talked about really focusing on profitability and all this success you've had with the burn and the pricing. But also talked in the prepared remarks you were disappointed with kind of the volume for 25, our how do we think about like kind of the guardrails, if you will, on your willingness or a in going after new doctors? Patients in terms of also balancing it against getting paid. So we'll get the update on the volume outlook in Q1. But I'm just wondering, should we expect kind of the number of ordering docs to go up like just can you speak through the methodology at which like you're seeking to grow volumes?

Absolutely, Dan.

So my comments a second ago are really just rooted in the fact that I think it's important to be transparent and honest in performance and objective as much as you can be. And we have high expectations for ourselves in really every area. So we always think that we can do better. I think objectively, if you were to look at our performance over the last two years, that would be the one area that you could point to and say, I would like to see this improve. That's exactly our mindset internally. We've dramatically enhanced the quality of our team. Over the last year. We've changed our sales leadership and happy to have someone that I've worked with at prior organization join. We've had a shift in the leadership underneath that person and the various reps throughout our territories of are of very high caliber. Now over the last twelve, eighteen months, we've made some changes there. So we have the right team in place. In terms of the trajectory from a volume growth standpoint, we expect it to improve. If you take a look at when we made these billing changes in the back half of twenty twenty three, we've been moderately up from where we were at the back half of twenty twenty three, that run rate.

And I expect us to maybe approach the high single digits From a volume growth standpoint, that's based on legacy growth rates. I do expect the volume of physicians to increase We're doing our first sales expansion since I've been here. This year. We'll add a handful of territories. So by all salient sales metrics, I would expect increases over the course of 2025. So number of physicians, orders per physician and overall volume.

And maybe just one for Jeff. Just on OpEx leverage, can you just remind us how implied in the guide, you talked a little bit about gross margins, kind of how do we think about OpEx leverage for the year?

Sure.

Yes. Dan, appreciate the question. So the way to think about this is that, yes, we will make some moderate incremental investment particularly on commercial and continue to invest in the R and D pipeline.

But think about the the level of revenue growth will outpace the level of OpEx growth. So we really will start to see some scale throughout 2025. And we'll see that in the margin as well. I think in terms of expectation, you really start to see that scale in the second half of the year because we've invested ahead of the curve. Particularly in laboratory operations. To accommodate the expected increase in demand. I think you start to really see that leverage in the last half of the year.

Terrific. Thank you very much.

Thanks, Dan.

Thank you. The next question is coming from Andrew Brackman of William Blair. Please go ahead.

Hi, guys.

Good morning. Thanks for taking the question. Maybe back to the example that you gave from Florida, it seems like the was sort of an uh-huh moment for that particular physician.

I guess on average, do you sort of have an estimate for how many tests of this new version might need to be ordered to get to that point where they see that benefit and it potentially drives more volume?

I guess related to that, any commercial strategies that you can deploy to maybe get them there a little bit faster? Faster?

Thanks.

Hey, Andrew. Thanks for the question. I think it's fantastic one and one we're evaluating internally. Although we've probably tested more people with these new biomarkers than had been done previously, I mean, in a given month, we're doing 10,000 of these tests plus. So So now a month and a half, two months in, we've tested close in the several thousand patient range. Still a little early to recognize the overall positive asking. And it's a good suggestion for our next earnings call to give to give some of that color. So I'll plan to do so.

But fantastic question. I think it also has to do a little bit with how are physicians using the test and what's their pretest probability that the patient has RA So it may be a little bit different on a physician to physician basis. But but we'll have that for you in the future.

From the standpoint of how to accelerate this individual experience for broader physician population, we're turning it into a case study. This is actually at the recommendation of the physician themselves. So using similar to how I described on the call, using a de identified example, but with enough specifics to show that it is true and real. And then to provide this in a few different context would I think be very useful. It'd also be nice to have some level of outcome data, which will take some time. But those are things definitely we're looking at doing and partnering with clinicians as as they use these novel markers. That's a great suggestion.

Okay. I'll be sure to ask it on the next quarter call as well.

Please. I guess maybe also here just on the pipeline, any catalyst that we should be sort of thinking about 2025? And then can you just maybe just give us a refresher on where that stands today?

Thanks.

Yes. So the major catalyst obviously was launched here in January with these new suite of markers. I think that's very key. We also expect to have sales expansion from a territory standpoint, maybe approaching the low 40s into the mid 40s. We're currently at 40 right now. So up to 10% growth in our territory volume. Those people will take some time to get up speed, but we do anticipate them contributing here in 2025. Our pharma business is going strong. It's been going strong here over the last call it, twelve months and we expect that to continue this year. And we also have a second wave of RA markers that we anticipate launching by year end, maybe early 'twenty six, that should further enhance that value proposition. So I would think that those efforts are going to be the major catalyst that will be most apparent in the operations of our business. I'll leave it at that. Thanks, Andrew. Thank you. The next question is coming from Matthew Parisi of KeyBanc. Please go ahead.

Hi, yes. This is Matt Parusi on for Paul Knight.

I was just wondering if you could provide a little bit more detail on the testing volume testing volume in general. If you maybe could give a number with that?

Yes. Hey, Matthew, good morning. And I'm assuming you're referring to 2024 testing volume as opposed to yes, not a problem. So total test volume for 2024 was 123,000 advised CTD units. That's down 11% relative to 2023. Keep in mind that the first half of twenty twenty three was record volume for the organization in both quarters. So as I said, comparing to the run rate post billing changes, you're up slightly to moderately since those billing changes. Does that answer your question?

Yes, perfectly. Thanks so much.

Yes.

Thank you. At this point, I would like to turn the floor back over to Mr. Abali for closing comments.

Great. Thanks all. As we wrap up discussion of our performance for 2024, our team remains highly motivated and committed to positioning our company for long term success. We are on track to achieve key milestones that will create value. And with this momentum, we're well positioned for an exciting year ahead. We appreciated your continued partnership and look forward to providing future updates.

Thanks.
