Good afternoon, and welcome to the ADMA Biologics Fourth Quarter and Full Year 2022 Financial Results and Corporate Update Conference Call on Thursday, March 23, 2023. Please be advised that this call is being recorded at the company's request and will be available on the company's website approximately two hours following the end of the call. At this time, I would like to introduce Skyler Bloom, Senior Director, Business Development and Corporate Strategy at ADMA Biologics. Please go ahead.

Welcome, everyone, and thank you for joining us this afternoon to discuss ADMA Biologics' financial results for the fourth quarter and full year 2022 and recent corporate updates. I'm joined today by Adam Grossman, President and Chief Executive Officer; and Brian Lenz, Executive Vice President, Chief Financial Officer and General Manager of ADMA BioCenters. During today's call, Adam will provide some introductory comments and provide an update on corporate progress, and then Brian will provide an overview of the company's fourth quarter 2022 financial results. Finally, Adam will then provide some brief summary remarks before opening the call up for your questions. Earlier today, we issued a press release detailing the fourth quarter and full year 2022 financial results and summarizing certain achievements in recent corporate updates. The release is available on our website at www.admabiologics.com.

And with that, I would like to now turn the call over to Adam Grossman. Adam?

Thank you, Skyler. Good afternoon, everyone, and thank you for joining us on today's call. We hope you all remain healthy and safe. During 2022, ADMA strengthened its position as the fastest-growing provider of immunoglobulin in the U.S. market, growing full year total revenues by 90%. Further, the persistence of encouraging business trends since the start of 2023 gives us confidence in our ability to exceed $210 million in full year 2023 total revenues as well as achieve first-time EBITDA profitability no later than the second half of 2023. Our organization's continued commercial success, we believe, is, in large part, attributable to ADMA's exclusive focus on targeting the immune-deficient patient segment, which is the fastest-growing cohort in the U.S. immunoglobulin market. We believe our innovative business model, unique immune globulin portfolio offerings and targeted medical education efforts in this PI subsector position us well for continued future success. We anticipate 2023 to be an inflection point for ADMA. Our organization aims to sustain top-tier revenue growth, achieve first-time EBITDA profitability and shortly thereafter, solidify the pathway to an ultimate margin profile at the upper bound of ADMA's plasma manufacturer peer group. Principally driving our confident outlook is due to ASCENIV, its uniqueness amongst immunoglobulin offerings and the real-world impact and improvements the drug is having on outcomes for problematic immune-deficient patients. Now well into 2023, we can confirm elevated ASCENIV utilization trends are continuing, and we believe that forward-looking demand indicators support product upside over the near term and longer term. The attribution of ASCENIV's growth continues to strengthen year-to-date as well. We are seeing encouraging signs of patient and prescriber persistence among those now entering their third year on therapy, which has been further compounded by a record expansion of new accounts as well as reorder velocity among existing customers. We continue to believe ASCENIV is trending to ultimately account for an even greater piece of our overall product mix than we have historically messaged. With our belief that ADMA's fundamentals are excelling and the pathway to EBITDA profitability is now well defined, we are pleased to highlight several newly identified growth opportunities that we believe can increase revenue and improve margins beyond our previously provided financial targets. Critical to note, we do not expect these incremental investments to compromise our strong funding position. Our emphasis remains on achieving near-term profitability, and we assure our stakeholders that pursuing these growth opportunities will not impact our forecasted cash flows but rather, if successful, will provide for meaningful upside to financial targets as well as compelling rates of return. First, among these opportunities, we plan to commence manufacturing ASCENIV at the 4,400-liter production scale for the first time in our corporate history. This expansion should significantly improve ASCENIV's margin profile as well as accelerated production throughput while requiring fewer batches to support revenue targets. We believe we are in the early days of ASCENIV's significant growth potential, and the expanded scale provides for uninterrupted production to support our forecasted rapid growth trajectory. We believe these benefits could materialize as early as the second half of 2023. The second growth opportunity we've identified pertains to yield enhancement, manufacturing and production processes, which have demonstrated proof of concept in our development laboratories during the first quarter of 2023. Pending additional evaluation, further validation of commercial scale production and future regulatory approvals, these yield enhancement initiatives could meaningfully increase both peak revenues as well as margin potential, if successful. Finally, our ongoing post-marketing clinical studies progressed as planned during the quarter and ADMA believes may ultimately provide opportunities for label expansion for both BIVIGAM and ASCENIV. Again, these opportunities represent potential upside to currently provided financial guidance. We look forward to updating the market as developments unfold. As we have communicated throughout our commercialization, ADMA's commitment to ensuring the continuity of patient care remains a top priority. Our strong RSV hyperimmune plasma and normal source plasma inventories, presently on hand, are expected to support all upwardly revised revenue forecasts for our immune globulin portfolio as well as may provide for opportunistic external plasma sales. The rapid expansion of our internal collection network, coupled with contractually secured third-party supply contracts, provide us with financial and supply chain flexibility. Currently, all 10 plasma collection centers in our network are operational, and 8 are now FDA licensed. We are clearly on track to achieve complete licensure of our BioCenters network as well as plasma supply self-sufficiency prior to year-end 2023. As a trusted partner with the local communities, we welcome donors to our state-of-the-art BioCenters to donate their lifesaving plasma, which allows ADMA to make its products. As always, our accomplishments and successes are the direct reflection of the commitment, passion and diligence of our employees. The collaboration among our staff, reinforced through the guidance of leadership and our advisers, embodies our corporate values to make the human connection a priority across all engagements. The transformation of our vision into the reality of assuming complete end-to-end control of operations is the result of our team's work and unwavering connectivity. We recognize and thank our staff arising to the challenge every day to continually meet our pledge to patients, the medical community, prescribers, advocacy groups and to our stockholders. Your efforts truly make a difference in the lives of those who are counting on us, and I thank you for all you do. Before turning the call over to Brian, I'd like to confirm that our strategic alternatives process remains ongoing, and exploring value-creating opportunities is the top priority for our company. The strategic alternatives process is separate and running in parallel to our pursuit of new growth opportunities, which I previously described. As developments occur, we will keep the market updated. With this said, I'd now like to turn the call over to Brian for a review of the fourth quarter and full year 2022 financials.

Thank you, Adam. We issued a press release earlier today outlining our fourth quarter and full year 2022 financial results, and I'll now discuss some of the key highlights. As Adam mentioned earlier, total revenues for the quarter ended December 31, 2022, were approximately $50 million as compared to $26.4 million during the fourth quarter of 2021. And this represents an increase of $23.6 million or approximately 90%. The revenue growth for the fourth quarter of 2022 compared to the fourth quarter of 2021 was favorably impacted by the continued commercial ramp-up of the company's IVIG product portfolio and the expanding customer base for BIVIGAM and ASCENIV. Our gross profit for the fourth quarter of 2022 was $14.2 million compared to gross profit of $3.5 million for the fourth quarter of 2021. Gross profit growth was driven by a favorable contribution from ASCENIV. Partially offsetting the favorably evolving product mix, ADMA sold a material amount of the remaining 2,200-liter scale, lower-margin BIVIGAM product during the fourth quarter of 2022. Excluding the impact of selling this lower-margin legacy BIVIGAM product, ADMA's estimated fourth quarter 2022 corporate gross margins would have been approximately 200 to 300 basis points higher compared to reported results. At the midpoint, this adjustment translates to an estimated operating loss for the quarter of $4.7 million, which is approximately 64% improved compared to the prior year's fourth quarter when accounting for transient gross margin dynamics, amounting to approximately $1.3 million. Due to the record product demand, ADMA currently expects to monetize a substantial portion of the remaining lower-margin inventory in the first quarter of 2023, incrementally earlier than previous expectations of midyear 2023. Our consolidated net loss for the quarter ended December 31, 2022, was $12.2 million or a $0.06 loss per basic and diluted share compared to a consolidated net loss of $16.6 million or a $0.09 loss per basic and diluted share for the quarter ended December 31, 2021. Our fourth quarter 2022 net loss decreased by approximately $4.4 million compared to the fourth quarter of 2021, and this was primarily attributable to the higher gross profit driven by sales of ASCENIV. We have significantly strengthened our balance sheet and funding position over recent periods. As of December 31, 2022, ADMA's total asset value grew to approximately $348 million, notably including approximately $163 million of total inventory, and this is recorded at the company's cost, approximately $87 million of cash and cash equivalents as well as accounts receivable of approximately $15.5 million. Lastly, we are very pleased with the expansion progress of our BioCenters plasma collection segment. ADMA BioCenters plasma collection network now consists of 8 FDA-licensed plasma collection centers with 2 additional plasma centers operational and collecting plasma, which are pending FDA licensure. The company remains on track to have the remaining 2 BioCenters FDA licensed by year-end 2023 and, in the same period, forecast raw material plasma supply self-sufficiency from all 10 BioCenters. Now several months into 2023, we are encouraged by the real-time improvements in donor foot traffic and plasma collection volumes, which are now considerably exceeding our organization's pre-pandemic levels.

Thank you, Brian. As in previous years, we've taken a conservative approach to constructing our financial guidance, considering various macroeconomic uncertainties. However, we are optimistic that we will potentially exceed our top and bottom line guidance ranges if current demand trends and margin dynamics continue. Our level of conviction is based on several factors. First, there is a 7- to 12-month manufacturing lead time for our products, which means that we can anticipate the impact of our past production efforts on our future financial performance with a unique level of visibility. This is unique to our industry because of these immune globulin-specific manufacturing lead times. Additionally, elevated product demand trends have not only persisted, but strengthened so far this year, which further bolsters our confidence in our forward-looking financials. Given these factors, we comprehensively reiterate all our previously stated objectives, including exceeding $210 million in total 2023 revenues and generating positive EBITDA no later than the second half of 2023. Regarding new growth initiatives, we want to emphasize that we do not probability adjust financial opportunities before receiving regulatory approval. Therefore, we will only include the potential financial contribution from these growth opportunities in formal guidance when we receive any such regulatory approvals. We believe our investments in the supply chain and commercial infrastructure in recent years have created a solid foundation for maintaining best-in-class revenue growth and potentially achieving an ultimate margin profile at the upper bound among our plasma product manufacturing peers. As a result, we believe we are well positioned for continued success in the future. In closing, I'd like to thank you, our stockholders, for your continued support, as your investment in ADMA helps to advance our mission to save lives and make high-quality, safe and efficacious products that help our friends, family and neighbors. With that, we'll now open up the call for your questions. Thank you.

Our first question comes from Anthony Petrone from Mizuho.

Congratulations on a strong end to 2022 and, obviously, the progress going forward here. I think, Adam, maybe I want to start just with guidance for 2023. The $210 million relative to $154 million in 2022, it's 36% year-over-year growth. And so it still is calling for a quarterly sort of step-up, I think, sequentially throughout the year. So maybe how should we be thinking about the quarterly complexion for 2023 and then the target for EBITDA positive by second half? Maybe just a little bit on sort of the first half, how that looks for EBITDA or just the progress to EBITDA positive. And then when we think about EBITDA positive in the second half, I mean are there sort of ranges we should be thinking about? And I'll have a couple of follow-ups.

Sure. Thanks for the question and for the continued support. Yes, this is always a unique time for folks like me because we're sitting here with about a week out from closing the first quarter and we're talking about how well we did last year, which I don't want to minimize. But look, we're very, very bullish on the persistence of top and bottom line trends. If you listen to the prepared remarks, and I'm sure you'll read the transcript later, we have incrementally tweaked the verbiage around EBITDA and profitability guidance and also revenue guidance. We really do take this conservative approach to setting targets. And look, we set targets that we can meet and feel comfortable about meeting in the face of all the macroeconomic challenges and other headwinds that we may face. We know that the market doesn't care about that. They want us to meet the guidance that we've set. So we are conservative, but hopefully, you read in the press release and you heard it in the prepared remarks that we believe that we've got an opportunity to achieve EBITDA sooner than the back half. And I think that if the demand trends and if the utilization that we've seen through the first quarter continues, I mean it will be another stellar year. I'm very proud of the progress that our company is making. And it's certainly based on the tremendous efforts across the organization. And from our production staff, our plasma collection staff, testing, facilities, the whole nine yards, I mean we are doing everything we can the right way. We make good products that are efficacious and help people. And we're really happy with the real-world evidence that's being disseminated out there. And quite frankly, we've seen some very, very strong utilization numbers so far this year. And I don't want to give away too much, Anthony, because the quarter is not done yet, but we do feel very, very strongly about our ability to potentially hit some of our milestones financially earlier than what we previously messaged. So hang in there, grab your popcorn, we're going to keep hitting it out of the park. And as long as the world continues to operate the way it is today, we feel very confident that we should meet or exceed all of our previously stated targets.

That's very helpful. Maybe just when we think about the $210 million and just the progress here, the prepared remarks, press release, you talk about just continued uptake of both ASCENIV and BIVIGAM but that you're adding new prescribers and patients, the reutilization rate for patients is sticky. So when you think about the $210 million, how much of that is just existing prescribers? And have you baked in incremental prescribers as well into that $210 million?

The prescriber universe for compromised patients in IG is certainly not infinite. There is a finite number of prescribers, and we've got a large amount of them who are believers in our products, who are believers in ASCENIV and who really understand now that this is really our third year of commercialization. I mean I think the message is out there. I think that the medical education work that we've done and our marketing activities have really carved out a nice niche for ASCENIV. And I think BIVIGAM, and some of the real-world evidence on great tolerability and efficacy, I think that this is really driving more awareness and increased utilization of the products. You asked something around reutilization of ASCENIV, and we're always a little bit cautious, if I can say that, flipping the calendar here. You never know what payers are going to do. You never know what occurs with Medicare and reimbursement. There's always some level of uncertainty. So we have to hedge a little bit. But with where we sit today, knowing what I know about the first quarter, I mean I'm really happy with the work that our med affairs and our market access teams, all the work that they've been able to do, I mean we are seeing continued utilization. And I know that this is something that our shareholders have been asking me about for years. They see this durable growth, 'Well, is it going to continue into next year?' And I'd say, 'I think it will. Let's flip the calendar and let's see.' And it appears that, that utilization is continuing. It appears that patients are staying on therapy. The docs are happy with the product. The patients who are thriving on the product certainly are advocating for themselves. And we built a night commercial and compliance infrastructure here to ensure that we have the data available to ensure the continued access of our products to patients who need it. So we feel real good about this. The $210 million includes, Anthony, existing prescribers. It includes new prescribers. We've got a very bullish commercial force right now, and they really feel like they're making a difference. Whether I should talk about this or not, we had our national business meeting. We had a couple of patients who received ASCENIV come in and talk to our commercial force about what their real-world life experience was prior to being on ASCENIV. And I think that, that really has reinvigorated and motivated our team to get out there and continuing to make a difference in patient lives. So the balls continue to bounce in our favor, and we're really happy, and we're going to keep making a good quality product and providing it out there and ensure the continuity of care. So we expect demand trends to continue, we expect utilization to increase and we feel very confident about exceeding that $210 million target that we've set.

That's great. And the last one for me, I'll hop back in and let others jump in here. Just on ASCENIV production scale going to 4,400 liter, what is the timing of that? And then if you can, can you just give us the total population of pediatric PI patients? Assuming you secure that label, how many pediatric primary immune patients are that are out there in the United States? Again, congratulations.

No, thank you, Anthony. So the ASCENIV 4,400 is something that some of my team finds amusing, as I had vowed never to pursue it. However, the demand has been excellent, marking a significant milestone for us. There’s strong demand for ASCENIV, and producing at the 4,400-liter scale will enable us to produce more product in a shorter time. This also opens up production slots. Whether we’re producing a 2,200-liter batch or a 4,400-liter batch, the same production slot, staff, and time are utilized. This will allow for increased production of ASCENIV, more BIVIGAM, and faster utilization of the plant’s overall capacity. Although I haven't checked the production schedule today, I believe we will likely start in the next calendar quarter for ASCENIV at this larger scale. We expect to see product coming off the line 7 to 10 months after that. We feel optimistic about this development as it signifies our growth as an organization, particularly in manufacturing. We have successfully executed hundreds of 4,400-liter batches for BIVIGAM, which our production and supply chain teams excel at, and I am very proud of their efforts. I appreciate the FDA's review of our submission, and this reflects our evolution into a more mature manufacturing organization. Regarding the percentage of pediatric primary immune deficiency patients, I don’t have that information at the moment, but I will follow up, Anthony, and you may include it in a note. We believe it’s beneficial for our label, as it is a federal requirement to fulfill pediatric study obligations. We want shareholders to know that we take our responsibilities seriously. We have finished the study for BIVIGAM, and the pediatric study for ASCENIV is currently underway. I think this may help attract more patients to the drug therapy. Yes, I believe there are pediatric patients using our products. This helps us align with several competitor products, and we are very optimistic about potentially expanding the label for BIVIGAM now that that study is complete and our regulatory packet has been submitted to the agency.

Our next question comes from Kristen Kluska from Cantor, followed by Elliot Wilbur from Raymond James.

Can you hear me all right?

Elliot, we hear you loud and clear.

Okay. Okay. A little bit of a challenge today getting into queue. Maybe I could start with a couple of questions for Brian, and just specifically thinking about expectations of positive EBITDA no later than the second half. I just wanted to confirm that the EBITDA metric that you're referencing is, in fact, an adjusted EBITDA number and would exclude stock comp expense. And maybe within that, if you could just give us a rough ballpark number of what you're thinking about in terms of depreciation expense. I think it was like $1.7 million last quarter. I don't know if that's just a good run rate to think about over the course of 2023 or not, but some color there, please.

Sure. Thanks for the question, Elliot. Yes, I would say if you were to look at our fourth quarter and even third quarter depreciation, amortization as part of our EBITDA calculation, which would be an adjusted EBITDA, positive EBITDA, no later than the second half of 2023, that would exclude stock-based comp, depreciation, amortization. While we haven't given formal guidance on ranges and dollars, we think it's a tremendous forward-looking accomplishment in a very short period of time. And then to follow shortly thereafter that, we feel very confident about our positive cash flow and profitability on or before the first quarter of 2024.

Okay. And if I may, an accounting question for you. Can you just talk about the plasma center collection costs on the P&L currently and how those would change or progress, I guess, as more collection volume is utilized for your own production? I seem to recall that some of that would get rolled into inventory and not be running through the P&L, but I just wanted to verify that and how we should be thinking about that with respect to your margin targets.

Sure. Again, thanks for the question, Elliot, regarding the plasma centers and expenses, especially from an accounting standpoint. So as our centers ramp up, there are initial marketing operational expenditures, administrative expenditures that are charged to the P&L upfront as an expense. Now as those centers start collecting and they receive FDA approval, the plasma itself that's collected is then allocated or earmarked charged to the balance sheet. So as all 10 centers are essentially up and running and collecting plasma now, as everyone knows, we have 8 FDA-approved centers. We expect to have the remaining 2 approved by the end of this year. Just this time last year, we had 6 operating centers and only 3 approved. At the end of 2022, we had 9 operating centers and 7 approved, and we just opened up our tenth center this quarter. So I would expect operating expenditures for the plasma centers to decrease because, as those centers now are all online, we're going to be able to continue to capitalize the plasma that we're collecting into inventory. A lot of those start-up costs have already been borne or incurred into those centers.

Okay. A couple of questions for Adam as well. Adam, can you just talk a little bit about what you're seeing on the demand side in terms of visibility on pull-through, whether you think, based on current production volumes, you're in a position to be competing for new customers? Or do you think the majority of finished product is going to go to existing customers? And then if you could share any anecdotes that you may be hearing in terms of reimbursement and persistence of therapy on ASCENIV, whether or not patients that start on ASCENIV are able to continue on it. Or are we seeing maybe an increase in cycling back to standard IVIG products?

I would make a note, Elliot, I'll try to touch them all. If I miss something, just ask. But no, thanks for the question. Not to sound like a broken record, but demand is strong. As I know you know, but for those who may not, who are listening, typically, if you're a primary immune-deficient patient, you have a genetic defect that requires you to get IG infusions every 3 to 4 weeks for the rest of your life. If you have secondary immune deficiency, depending upon your condition, if it's an organ transplant, you're immune compromised for your life, so you typically may stay on IG for longer periods. If you had a bone marrow transplant or maybe you're getting some type of short-term monoclonal therapy that renders you to be immune compromised, you may be on IG for a shorter period of time. But what we're seeing is we're seeing continued use by our existing customers. Obviously, there's growth. We've been ramping up our production throughput over the last year, 1.5 years. And as we said last year, and as I said in the prepared remarks, we've got unique visibility because the product that we're selling today, we made last year in the second quarter. So we certainly have the inventory there. I mean we ended the year with approximately $160 million of inventory. And we feel that, that certainly will support $210 million or more in top line revenue. But it's durable, Elliot. And we're seeing continued utilization by existing patients and prescribers, and we are seeing new prescribers being added every month, every quarter. We're also self-regulating. I mean we kind of live in this world that's a little different than some of the larger players in the immunoglobulin space. Again, we're really 99% outpatient. We work with great specialty pharmacies, great home infusion and freestanding ambulatory infusion clinics as well as doctors' offices that do IG infusion. And we're really building brand loyalty. We're building great relationships with our prescribers and these infusion pharmacies. And we're able to really I don't want to say choose who our customers are, but we're working with folks that, a, pay their bills on time; and b, order and stock inventory according to contract. It's a symbiotic relationship. We guarantee the continuity of care with our supply, and they have it available for their patients when they need it. Again, we're the only IG manufacturer who's not pushing any other plasma-derived therapy. So we don't have to sell albumin. We don't have to sell coagulation factors. We're not selling any other novel unique plasma protein. So we really feel very good about the position and the demand utilization. The inventories in the channel are normal, if not a little bit thin, depending upon the vial presentation. But I can tell you that we are committed here and we are pushing more plasma into the plant than ever before to ensure that continued growth trajectory for both products. You asked a question about persistence of patients on ASCENIV therapy. A lot of people ask us that same question, Elliot. I know that they ask you that question, and I'm sure that they ask the other analysts as well. And what I can say is, yes, the patients that are starting on therapy, based on the input and data that I have available to me, the majority of patients that were on ASCENIV at the end of last year are continuing on therapy at the beginning of this year. I'm aware of very few patients that have come off therapy and switched back to normal IG. Obviously, as people change their insurance or as they move to different states, as they have changes in their life, things certainly happen. But I can tell you that the patients that are being monitored by the clinicians are remaining on therapy. It's durable. There's no seasonality in the utilization of ASCENIV. I think that's something that I think is a question we also get, Elliot. What more can I say? I know too much about the first quarter, and I'm trying very hard to keep my mouth shut. But I just think that we will continue to see record utilization and pull through for BIVIGAM and ASCENIV as we progress throughout 2023. We wouldn't be this optimistic about our financial guidance and increasing and tweaking the language, I mean we do take it very seriously. For those of you who are listening, I probably know most of you, and I've known you for years, and I like to under promise and over deliver. My team enjoys it as well. Last year was a tremendous year for us across all measures. And we want to set targets that are achievable, that we believe we can easily meet in the face of macroeconomic challenges but also that we have a high likelihood to beat. So yes, durable utilization for ASCENIV, durable pull-through. My commercial team has promised. And sometimes I look at them and I go, 'All right. Show me, prove it,' and they're doing it. So unfortunately, I don't make the rules. The SEC said we filed first quarter numbers on or before May 15. I think that investors and our analysts, you can anticipate continued durable utilization, continued patients on ASCENIV therapy and growing BIVIGAM utilization across the IG and immune-compromised patient landscape.

Got it. One more question, if I may, and hopefully, I didn't miss this in your prepared commentary. But can you just talk a little bit about what you're seeing in the collection center level in terms of the capacity utilization of the various centers, donor and foot traffic trends? There's been some media about very heavy volumes at the border, at the U.S. Mexican border. I know that doesn't directly impact your business, but just wondering if there's any corollary there. And then more specifically, given the strong performance of ASCENIV, I know that you still have the ability to source high RSV titer plasma from your prior supplier, but maybe just talk a little bit about what you're seeing in terms of your internal sourcing of high RSV titer plasma at your captive collection centers?

So Elliot, I'll take the plasma center question. Yes, visibility has never been higher on our pathway to supply self-sufficiency at our centers. We received, I would say, accelerated approvals last year. All 10 centers have been opened and are operating and collecting. So we're clearly on track to receive FDA licensure for call it the remaining 2 by the end of this year. All the centers are operating very well. Foot traffic certainly above where we were pre-pandemic and collections are certainly meaningfully exceeding our pre-pandemic levels. As it relates to collections for BIVIGAM, ASCENIV and even Nabi, for that matter, yes, we have some other third-party contracts, but our own source plasma from our own 10 centers will more than meet the demands for the revenue forecast that we've set over the next couple of years. But our goal is to collect as much plasma as we possibly can. Plasma is going one way, and we feel very confident in our collection abilities and getting these centers open and approved.

And I think we messaged in one of the last quarter call or maybe it was during the financing, we've invested into our own laboratories here, and we've identified ways to potentially screen and identify the hyperimmune RSV plasma donor faster. And as we continue throughout 2023, we think that we'll be able to shift to more of this testing in-house. And I think that, that will help us to ensure that we have as much plasma as we need to make ASCENIV and as much normal sources we can get. I think also something that our team always works on here is third-party supply contracts where we're even working with some new collectors now potentially bolstering and augmenting our internal supply and our existing third-party contracts with some new ones. These are not huge quantities of plasma, but every batch is 4,400 liters. And if we can get more plasma, we can produce more, we've got more production slots available switching ASCENIV to the 4,400-liter scale, and it's all falling into place. So I'd like the inflationary headwinds to subside just because it's crazy out there. But it certainly has not been slow for our collection centers. So we're really, really happy with the job they're doing. And from what I can see, we've got good inventories of material, Elliot. So I don't foresee any issue with us meeting or exceeding even the out-year revenue and financial targets that we've set for the business.

And our next question comes from Kristen Kluska from Cantor.

Congrats on a great 2022 and continued success, really, especially when you consider coming back from some of the hardest times of the pandemic and the macro environment we're in. So I wanted to ask, given your initiatives to unlock new growth opportunities, Adam, you started to comment about ways you're looking to measure and source more plasma from those with sufficient levels of titers to RSV. So I know there's just a small percent of people who have these levels. But naturally, if your footprint is increasing across your centers, I would imagine that you're collecting more of this plasma. So how could this initiative and some of these changes also help to consider some of your revenue goals and even potentially exceeding them?

Thank you for your continued support and the great question, Kristen. I hope you’re doing well. In our public filings, we mention that approximately 10% of people have the titers we seek. The advantage of collecting most of this plasma ourselves is significant. We still collaborate with Grifols, and our supply contract is secure until mid-2027. We also work with a few smaller collectors of high-titer RSV plasma. However, while I can’t mandate that a particular donor comes back, I can direct our plasma collection centers to reach out to donors known to have high levels of neutralizing antibodies to RSV. We can implement incentives and create a welcoming environment, which provides us greater control over the donors we attract. Although only around 10% of the population may have the desired antibodies, this doesn't limit our ability to collect high-titer plasma because we can manage which donors visit our centers. This process combines both science and art, and we take it very seriously, implementing targeted programs to engage these donors. Achieving this level of control aligns with our 2020 goal of enhancing supply chain robustness. While we can’t dictate exactly who donates on any given day, we strive to motivate and encourage RSV high-titer donors to return. Regarding growth opportunities, the 4,400 scale will certainly increase access to ASCENIV and open up more production slots for our immunoglobulin products. We are also excited about our potential yield enhancement initiatives. We're exploring the use of some discard fractions that contain immunoglobulin. If we can successfully harvest from this product, it will require some comparability work and regulatory submission to the FDA, but we believe it would involve a relatively modest investment. These yield enhancement initiatives and improvements to our RSV testing capabilities will require investment, but they won’t significantly affect our cash reserves or profitability outlook. We view these as low-cost actions that can yield significant financial benefits. While we're not yet ready to quantify these impacts, we anticipate a revenue split of 70-30 or 60-40 between BIVIGAM and our higher-margin hyperimmunes, ASCENIV and Nabi-HB. Nabi remains strong, with margins around 60% to 70%, and we value that product. ASCENIV operates in the 80% margin range, while BIVIGAM’s margins are improving to the 30% to 40% range. We believe we can achieve gross margins of 50% to 60%, contributing 25% to 30% to our bottom line, which makes us optimistic. As we enhance our fill-finish capabilities and hopefully unlock additional yield through various process development initiatives we've started in the first quarter, I see our current guidance as just the beginning. We cannot accomplish everything at once, but I feel confident that our company is equipped with exceptional leaders and staff, positioning us for ongoing success and growth.

And now that you have a lot more experience with ASCENIV, and I know that you opined in the press release that publications are potentially in the works, looking back at the clinical trial experience, I think you had about 60 patients there. So I'm wondering, now that you have this kind of real-world experience, if the effects that you're familiar with at least are in line with what's on the label, if you're seeing even better benefits if patients are on the treatment longer? Really, like anything that you can help us understand outside of just the label experience.

I hear my compliance team cautioning me, Kristen. There have been some publications out there, along with data from certain key opinion leaders in the field. We’ve also shared a few publications at medical conferences and meetings. While I could speculate privately with you, I don’t have strong data to share at the moment, and I don’t believe it would be appropriate to do so. What I can say is that I strongly believe clinicians will prescribe products that are effective. A label may prompt them to try a product, but they will not continue therapy if it does not perform as expected or better. Especially considering the price of ASCENIV, expectations are high. The best response to your question is that we are observing consistent reordering patterns, durable utilization, and increased demand. This suggests that the product is achieving results that exceed even those seen in clinical trials. Our data for ASCENIV, although not a direct comparison to other IG products, indicated a very low rate of antibiotic use, few missed days of work and school, and a low rate of hospitalizations. Anecdotally, patient diaries also indicate that users felt good while on the product. If you visit our asceniv.com website, you'll see this product is not suitable for everyone. It is specifically intended for patients with chronic and persistent infections who are not thriving on standard IG therapy and need an alternative. We heard this sentiment from ASCENIV patient representatives at our national business meeting. I genuinely believe that there is something distinctive about the antibody profile of the product. I see RSV as a marker for these high responder donors, and some data has been published on that. The continuous growth of the product supports my thoughts. I hope this addresses your question without causing any compliance issues for me. I anticipate more data to emerge, and as we enhance product utilization and penetration, I am excited about the future for the immunocompromised population and our company.

Great. Looking forward to seeing what you have in store for us this year.

Stay tuned, Kristen. We will hopefully not disappoint.

Ladies and gentlemen, this concludes our question-and-answer portion of the call. I'd like to turn it back over to Adam for additional closing remarks.

Thank you, everybody. I just want to thank you all for your interest in ADMA Biologics. We appreciate your continued support. Donate plasma, you've got plasma centers near you. And we hope to continue to keep the shareholders happy, keep the patients happy. And again, thank you to my staff, the whole team, we can't do it without you. So all of our advisers and everybody, keep fighting the good fight and rock on. Take care, everybody.

Thank you. Ladies and gentlemen, this concludes the conference call for today. We appreciate your participation, and you may now disconnect.
