Thank you, Kendall. Good afternoon, everyone, and thank you for joining us on today's Investor Call. We delivered another quarter of strong financial performance. In the fourth quarter, revenue was $33.8 million, growing 16% year-over-year with net income of $4.1 million. So for the full year of 2025, we delivered $129.4 million in net revenue, representing 30% growth year over year, and net income for the year of $17.4 million. We ended the year with $64.8 million in cash and no debt. I'm very proud of what the nitrogen bio team accomplished in 2025. We began the year with an initial top-line guidance of 18% growth and finished the year at 30%. And we dramatically exceeded expectations on the bottom line as well. But most importantly, we're well-positioned to deliver a great 2026. There are some challenges. There's increased competition in this fast-growing NAD space, space that is only hitting the tip of the spear but we have spent many years laying a strong foundation we have the expertise we have the intellectual property we have the relationships and we have the trusted brand we're ready to build on this foundation the most critical element of this foundation is our science nitrogen bioscience continues to be the undisputed global leader in NAD science. Since our last earnings call, a total of 29 studies involving nicotinamide riboside were published. Eight of these studies were clinical studies. So I've asked Dr. Andrew Schauer, Senior VP of Global Scientific and Regulatory Affairs, to summarize some of these studies on this call. Of note is a study out of Finland that showed NR supplementation slowed biological aging according to several epigenetic clocks. Also, a comparison study from Dr. Tozulis in Norway between NR and NMN that showed significant superiority of NR. We're seeing some consistent trends in these studies that show fatigue to be a consistent positive functional benefit from NR, as was displayed in the recent Harvard long COVID study. Some of these studies did not show a clear benefit, such as the No Parkinson's study, but still provide great learnings for future research. We can see how elevating NAD with Niagen improves people's lives, and we will continue to further our understanding of how it works, when it works, and how to best deliver it. Another important component of our foundation is Niagen Plus. Last week, we announced that the company secured a patent that covers the methods of use of NR and derivatives in intravenous and injectable formulations. There is great opportunity for Niagen Plus. We're now present in over 1,200 health clinics and will be adding doctor's offices and med spas this year. Now, those locations mostly offer Niagen IV, but we plan to launch our Niagen Plus branded at-home injection kits through our own telehealth platform during the first half of 2026. And we hope to partner with other telehealth providers to distribute our at-home Niagen Plus injection kits later in the year. We also plan to expand our presence in the beauty cosmetics market this year. Following the successful launch of TrueNiagen Beauty in late 2025, we've developed topical products featuring Niagen. In addition to our own TrueNiagen-branded topical products, we're in discussions with large cosmetics companies for Niagen ingredient partnerships. And I hope to share more about these partnerships in the near future. As mentioned on the previous earnings call, last September the FDA reversed its prior determination that NMN could not be lawfully marketed as a dietary supplement. This decision by the FDA has been met with confusion within the industry as the agency did not provide a clear rationale for its seemingly arbitrary reversal. Earlier this year, we commenced litigation in federal court in Washington, D.C., challenging the FDA's reversal. We believe we have a strong case. And as a reminder, all NMN sellers in the market are at their own risk as they are all infringing on existing patents that cover the commercially available forms of NMN. Last December, we announced the acquisition of existing patents for multiple NR salt forms, including NR malate and NR tartrate and other NR derivatives. This consolidation of core intellectual property not only provides protection to Niagen in the marketplace, but also provides the company with enhanced flexibility and control over our portfolio to advance innovation in NAD science. And we continue to work with our NAD precursor portfolio for pharmaceutical applications and orphan indications, particularly ataxia telangiectasia. We've identified NB4168 as our lead development small molecule candidate for AT. We intend to continue to make strategic R&D investments to further characterize NB4168 with the long-term objective of advancing toward regulatory approval. Potential value creation pathways for this asset include a spin-out transaction or an out-licensing partnership. We'll continue to update shareholders as we achieve key development milestones. And last month, we announced the sale of the Chromadex reference standards business. This divestiture further streamlines Niagin's operations, advances the company's strategy to exit non-core activities, and focuses resources on NAD science, intellectual property, and commercial growth. NAD Plus remains at the forefront of health and longevity discussions with continued coverage across mainstream press, healthcare practitioner channels, and general discourse with consumers on social media platforms. NAD is not just a trend or a fad, it is a fundamental component to cellular health and overall healthy aging. While awareness of the benefits of NAD is expanding, we believe that the category has not yet reached its tipping point. As I repeated in the past, NAD itself, the molecule NAD, in any form of administration collaboration is not proven to directly and effectively boost NAD levels. Individuals require an NAD precursor to properly boost NAD levels, and Niagen remains the gold standard for NAD precursors and remains the most trusted and clinically and scientifically validated solution to effectively raise NAD levels. As the leader in this space, we will continue to stand by our scientific research to drive innovation, and I look forward to future announcements of new ways and new products for Niagen to benefit everyone's lives. And I would now like to hand the call over to Andrew to provide an update on this scientific research. OZON will then run through the financial performance in greater detail, our outlook, and we will then end on Q&A and closing remarks. Andrew?

Thank you, Rob. It is my pleasure to address our investors, partners, and employees and provide an update on the state of NAD science. As the leader in NAD science, Niagen Bioscience is committed to remaining the global scientific authority on NR and NAD research. I'm pleased to share some of the exciting results from newly published studies since our last update. On our last earnings call, Rob briefly touched on the completion of a study involving individuals with long COVID conducted by Mass General Hospital. The study, published in the November issue of The Lancet eClinical Medicine, demonstrated NR supplementation resulted in significant within-group improvements in executive functioning, fatigue severity, sleep quality, and depressive symptoms. These findings highlight a therapeutic potential for those that are impacted by long COVID, but also reflect promising benefits of of NR supplementation are general challenges, such as fatigue, sleep, and depression. Regarding Parkinson's disease, as Rob mentioned in his remarks, the NO-PARC study did not achieve its primary endpoint. We've been in close contact with the investigators from Hawkland University Hospital in Bergen, Norway, led by Dr. Charolampos Tuzoulas. We, together with Dr. Tuzoulas, believe when it comes to Parkinson's, the benefit of NAD augmentation with NR may be best applied prior to disease and treatment onset, in other words, as a preventative. We plan to collaborate with Dr. Tazoulas to examine the preventive effects of NR and its mechanism related to Parkinson's through a new partnership we will announce soon. In the meantime, Dr. Tazoulas is continuing his research on the therapeutic effects of nr in parkinson's and other neurodegenerative conditions including als and ms in january a clinical study published in the prestigious journal cell assessed the pharmacokinetics and systemic and brain impact of oral supplementation of any precursors including a head-to-head comparison of niagen and nnn one of the key findings was that Niagen produced approximately a two-fold greater increase in blood NAD levels compared to NMN, even after accounting for the molecular weight difference, underscoring the superiority of Niagen. Another study released in January assessed the impact of NR supplementation and high-intensity interval exercise training on epigenetic age acceleration in human blood and skeletal muscle using a collection of different biological clocks. Interestingly, results showed that Niagen reduced epigenetic aging while high-intensity interval training resulted in increased epigenetic age metrics. The findings suggest that NR supplementation and exercise may differentially modulate the aging epigenome and that metabolic interventions and intense physical activity They have distinct impacts on muscle aging biology. Two recent preclinical publications highlighted NR's positive effect on brain health. First, in November, a preclinical study investigated the impact of NR supplementation on cognition, neuroinflammation, and microglial cell metabolism in groups of young and old mice. Results showed NR supplementation in the old mice prevented cognitive decline, improved memory, produced neuroinflammation, and shifted microglial metabolism toward that of a young mouse. A second preclinical study published in February in the journal Brain used both nematode and mouse Alzheimer's models to assess the upregulation and activation of an important transcription factor linked to Alzheimer's disease progression known as REST. Next, the study found that increasing NAD levels through NR administration increased rest expression and activity, which led to improved mitophagy and synaptic function. And in the case of the nematode models, extended lifespan. Collectively, these preclinical studies helped to elucidate the mechanisms behind the therapeutic effect of boosting NAD through NR in the brain. In February, a study demonstrated that maternal supplementation improved gestation, litter weaning weight, weight gain, and improved milk yield and composition, among other beneficial effects in sows. These findings are remarkably consistent with those first published in 2019 by Dr. Brenner, our chief science advisor, who showed similar effects in rats. We eagerly await the results of an ongoing clinical study being conducted at UC Davis examining the effect of niagen supplementation on lactation in mothers who have given premature birth. In preparation for the launch of niagen injection, we've just completed a clinical trial investigating the safety and efficacy of intramuscular and subcutaneous injection. Both modes of administration were demonstrated to be safe and were associated with reduced fatigue, improved quality of life, trends toward improved sleep, and lower oxidative stress. Another recent clinical study conducted by our partners at Restore Hyperwellness compared Niagen-IV and NAD-IV in a head-to-head study to assess infusion time, tolerability, safety markers, and metabolic outcomes. The study published in the journal Frontiers in Aging revealed that Niagen IV was far better tolerated and required only one-third of the infusion time versus NAD IV, findings consistent with our own Niagen IV versus NAD IV clinical study. Furthermore, Niagin IV resulted in a small but statistically significant reduction in HbA1c, the biomarker of diabetes, whereas the NAD IV group showed a small but significant reduction in HDL, or good cholesterol. With now two independent head-to-head studies, the results are clear. Niagin IV is far superior to NAD IV. Nonetheless, we will continue to expand the evidence base around Niagen Plus and plan to conduct larger, longer term studies to replicate and expand upon these results. In summary, Niagen BioScience continues to advance NR and NAD research and doing so with responsibility and integrity. The growing body of clinical research supports the potential therapeutic benefits of NR administration and I look forward to potentially sharing more results in future updates. With that, I'll pass the call over to Ozan. Ozan?

Thank you, Andrew, and thank you to our investors, partners, and team members for joining us today. It is a pleasure to speak with you and to present yet another quarter of outstanding results. As Rob highlighted, 2025 was another strong year for Niagen Bioscience. as the company delivered on its latest financial outlook across all metrics. The results of the fourth quarter and the full year is a reflection of our team's dedication to delivering shareholder value by advancing strategic initiatives and maintaining Niagen Bioscience's position as the gold standard in NAD science. For the full year, we delivered $129.4 million in net sales, up 30% year-over-year, which is well ahead of the 18% growth we guided to at the start of the year. Gross margin came in at 64.3%, reflecting improvements in operational efficiency. On the expense side, we continued to scale with discipline. Selling and marketing expense improved by approximately 220 basis points as a percentage of net sales year-over-year, while R&D investments increased by $300,000. dollars. General and administrative expense was up $8.7 million year over year, primarily driven by an increase in employee-related expense and stock-based compensation of $3.8 million, increase in consulting fees of $1.5 million, and higher royalty expense of $2.9 million due to the absence of a $3.5 million reversal of previously accrued royalties and licensed maintenance fees which occurred in the prior year under operating income we also recognized a two million dollar gain on settlement of royalty obligations in connection with our agreement with queen's university belfast net income for the year was 17.4 million dollars compared to 8.6 million dollars in fiscal year 2024 and we generated 13 and a half million dollars of cash from operations. Lastly, adjusted EBITDA for the year was $20.4 million, an $11.9 million improvement compared to fiscal year 2024. Our revenues in the fourth quarter of 2025 were $33.8 million, a $4.7 million, or a 16% increase from the same period last year. That growth was led by True Niagin, where revenue grew by 21% to $27.5 million, a $4.8 million increase. The primary driver was e-commerce, which generated $20.2 million, up 17%, or $2.9 million. On the ingredient side, Niagin ingredient revenue was $5.6 million, up 5%, or $300,000 year-over-year. And within that, we delivered $4.7 million in food-grade Niagin sales, along with $900,000 in pharma-grade Niagin sales. In the fourth quarter of 2025, revenue from our B2B distribution partners totals $7.3 million, driven by contributions from existing and newly established strategic partnerships, such as the one Rob mentioned earlier. Although we continue to anticipate quarterly fluctuations in sales to Watsons, we expect the partnership to remain an important component of our broader distribution network as we partner closely with Watson's on strengthening TrueNiogen's brand presence in Hong Kong and expanding into additional Asia-Pacific markets. Gross margin improved to 64.1% in the fourth quarter, up 160 basis points compared to 62.5% a year ago. That expansion was driven mainly by a more favorable product mix, along with the benefit of selling through lower-cost inventory. Selling and marketing expense was 30.8% of sales in the fourth quarter, compared to 29.9% in Q4 2024. This reflects our continued targeted investments to build global brand awareness while staying disciplined and focused on operational efficiency. Research and development expense was $1.7 million, up $400,000 year-over-year. Scientific integrity remained the cornerstone of our company and we continue to invest strategically to deepen the clinical evidence behind Niagen and support innovation in the NAD industry. General and administrative expense was $7.5 million, an increase of $6.4 million versus last year. The primary drivers were the absence of a $3.5 million reversal of previously accrued royalties and license maintenance fees, along with higher share-based compensation expense. And finally, our net income for the quarter was $4.1 million, or $0.05 per share, another profitable quarter to close out the year, and a clear reflection of our continued focus on discipline execution. Turning to the balance sheet and cash flow, our balance sheet continues to strengthen. On the back of this year's growth, we ended the year with $64.8 million in cash and no debt, reinforcing the financial flexibility and stability of our business. The full year 2025, net cash provided by operations was $13.5 million, compared to $12.1 million in the prior year. The year-over-year improvement was mostly driven by an $8.8 million improvement in net income, along with several favorable shifts in operating activities compared to the prior year period. Specifically, we saw higher accounts payable and prepaid expenses, improved collections on trade receivables, higher share-based compensation, and the absence of last year's reversal of previously accrued royalties and license maintenance fees. Those benefits were largely offset by growing inventory levels to support the scaling of our business, which were significantly depleted at the beginning of 2025. As Rob mentioned earlier, last week we announced the sale of the Chromadex Reference Standards business in a $6 million all-cash transaction adjusted for working capital. This was a non-core legacy business that generated approximately $3 million in 2025 and was not a profit center. This divestiture is a meaningful step for nitrogen bioscience to streamline and focus operations on advancing NAD science, which will result in efficiencies in our resources and capital allocation and a boost in our cash reserves. Finally, I will close with our full year 2026 outlook. Detailed information on key financial metrics can be found in our earnings press release and presentation. Starting with net sales, for full year 2026, we're projecting between 10 to 15 percent growth year over year, excluding revenue attributable to the analytical reference standards and services segment. This outlook reflects continued scaling of our e-commerce business, growth from our established partnerships, and additional upside from newer partnerships and sales channels. We anticipate a slight improvement in gross margin as we continue to benefit from improvements in our supply chain and product mix. Selling and marketing expenses are expected to increase in absolute dollars but remain stable as a percentage of net sales, which was 27.4% in 2025. This demonstrates our continued focus on strategic investments to drive brand awareness and support the launch of new channels and verticals while maintaining optimized and efficient spend in customer acquisition. R&D expenses are also expected to increase in absolute dollars, driven by incremental investments in pharmaceutical development and external research initiatives to advance product development and innovation. And lastly, general and administrative expenses are expected to increase by approximately approximately $4 to $5 million in absolute dollars year-over-year. This increase is primarily driven by investments in infrastructure to support scalable growth and increased share-based compensation expense. To conclude, 2025 marked another year of disciplined execution and meaningful progress. I am proud of the focus and dedication our team showed in delivering on key initiatives. work that continues to strengthen Niagen Bioscience's position as the leader in the rapidly expanding global NAD market. Their efforts reinforced our operational foundation, advanced strategic priorities, and positioned us for long-term success. With this momentum, we're entering 2026 with confidence as we continue executing our vision and deliver lasting value to our stakeholders. Operator, we're now ready to take questions.

At this time, if you would like to ask a question, press star, then be number one on your telephone keypad. To withdraw your question, simply press star one again. We kindly ask that you limit your questions to one-on-one follow-up and return to the queue for any additional. We will pause for just a moment to compile the Q&A roster. Your first question comes from the line of Jeffrey Cohen with Leidenberg-Bowman. Please go ahead.

Oh, hey, Rob, Andrew. Hey, Jeff. Thanks for taking our question. So I guess firstly, could you jump into the injections? So I think you have one SKU now for the IV beds and injections to come. What are you expecting on number of SKUs, or would that be just one? And initially on your own telehealth platform, and then on the back half here, you're expecting and you get on to other platforms and talk about the audience there as well being the overlap with the current clinics.

We will initially have just one SKU. We think that the market, the audience, as it were, for the product will initially be the biohacker community, the people that are especially excited about longevity interventions, people that are presently doing peptides. We think it'll grow to expand to include some people who are doing presently GLP-1 agonists. We think there's a market out there for people who are interested in self-injecting to stay thinner. Mice will be interested in self-injecting to stay younger. The initial product will be a syringe and we'll we'd be separating the powder from the liquid so it's a slightly complicated process so the more sophisticated and more people that are more used to this process will be the early adopters eventually it'll be in a pure liquid form and a much simpler process and even after that will be a pen that looks much more like the glp1 pens uh in terms of the uh overlap with the clinics well the price point is significantly different and the dosage is significantly different the clinics are mostly giving 500 milligrams to a full gram in one session these will be 100 milligram injections initially and people will do it you know a few days or three days per week so we think it's slightly slightly different audience in terms of dosage and then in terms of price point we expect that the injections the shots will be less than half the price as the current than the ivs now on the other hand the ivs in some ways because it doesn't because it's not sub q it's directly into the bloodstream uh are even more effective uh so that's that's how we differentiate those two products andrew is there anything else you want to add to that?

No, I think you covered it, Rob.

Okay.

Is that up? Yep. Thank you. And then just one follow-up. Can you talk about your guidance, I guess, briefly, where you did call out last year that the guidance started out in the high teens and literally doubled as the year went on. So is this kind of cautionary guidance to get started on the year subject to revisions down the road, or is this something that you feel pretty strongly about the full year?

I would say the former more than the latter. I think we've been pretty consistent over the years. We don't want to hype the company or hype the stock. We want to be conservative in our approach circle revenue that we have a high degree of confidence in remember a big part of our business also is b2b where we supply the ingredient and that's far less predictable than the straight e-commerce business as it were perfect thanks for taking the questions your next question comes from the line of susan anderson with canaccord genuity please go ahead hi thanks for taking my questions um maybe if you could kind of parcel out i guess or what you're seeing is the growth drivers for this year between i guess the original um in our supplement and also the iv and then also the new products that you're rolling out such as like beauty supplement in terms of growth correct yeah and then also just any new channel distribution you're expecting to go into yes we do the latter portion first we do expect to expand the distribution channels uh we we will be expanding into certain selective retail channels and even by the end of the year we might even broaden that further we are expanding also internationally into some territories particularly in asia and perhaps in the eu in terms of the growth products. Of course, awareness for Niagen and True Niagen continues to grow. So we think there's just basic organic growth as more and more people write about Niagen Bioscience as a company and True Niagen as the products. And we continue to conduct these studies and go on podcasts. And there seems to be a general acceptance amongst those that do the research that we are the reliable brand, the reliable company, and the experts in the space. So we do see just steady, consistent growth in our existence with the existing cronigen products and the existing channels. But it's difficult to know how much the cosmetics products and the IV and the injection products will grow. So we are endeavoring to give conservative assumptions there. Until we're out there and we see how the market reacts to it, we don't really know yet. But, of course, the upside potential is fairly significant, we think. And we just don't really yet know how it's going to break down.

Okay, great. That's helpful. And then maybe you mentioned just, you know, increased competition in the space with, you know, NMN now. Now, I guess, what do you guys, you talked about, you know, getting out there on podcasts and stuff. I guess, what are you guys, you know, doing this year to kind of get the message out there to consumers, maybe getting them to switch over to your product versus, you know, a different product that they're taking right now?

Well, of course, we have the best product. I mean, the ingredient that we sell is the most effective. Our quality team is the best quality team. The way we operate the business. And we have a high degree of confidence, as do most people in the industry, know that the best way, safest way, the most tested way, the most informed company to elevate NAD levels is to take Niagen or TruNide. We do see increased competition. NMN did get reversed by the FDA. They're ruling. We think there's a good chance they're going to re-reverse that decision in the coming year. And, of course, all those NMN products are infringing on patents. So the only companies you're seeing selling NMN are companies who never really cared about the FDA ruling in the first place and now don't really care much about the patent rules. But it is increased advertising that you're seeing. Most of that NMN is cannibalizing NAD itself. You know, these are companies that were selling NAD as a molecule in a bottle, which doesn't work at all. You know, it's not bioavailable, doesn't elevate NAD. So what we're seeing is transfers from NAD selling over to NMN selling. But our view on it is pretty much the same as it was when NAD was growing, which is it only helps increase the market. You know, we'd rather have 20 percent of $10 billion than 50 percent of $500 million. You know, they're advertising it. Many of them get it wrong. they make false claims, but many of them get it right. And they're explaining to people that elevating NAD is good for your health, especially as you age or as you heal. And the more you research, the more you realize that the best way to manage it is with niagen or true niagen. Yeah, we think what we've seen is that when people, sometimes they'll start out by taking NAD or NMN or NMNH or something that the low price version of a product that markets NAD. And if eventually they come up, they come around to reading the science or reading our marketing materials, they come around to true nitrogen. And then the first part of your question. Yeah, it's, there's a very good chance that sometime during 2026, we will launch a more aggressive awareness brand type campaign for the company, especially if we expand into certain retail outlets to increase awareness and brand familiarity. We're working on that present.

Okay, great. That's really helpful. Thanks so much.

Good luck to be here.

Thank you, Susan.

Your next question comes from the line of Ram Sovaraju with H.C. Wainwright. Please go ahead.

Hi, thanks very much for taking my questions. I was just wondering if you could comment at this point regarding what you anticipate the next steps to be in the lawsuit filed against the FDA and the associated parties regarding the influx of NMN products, and also if you could give us a sense of what percentage of prosecution of that legal initiative is represented in your overall legal expenses anticipated for 2026. Also, if you could please comment on how you are thinking about future evolution of your share repurchase strategy. Thank you.

Hey, Rob. We don't think it's going to be a significant expense. We think that this is going to be a summary judgment case. we think both the FDA and we would prefer a summary judgment, so it's likely to go that way. They've selected a judge. They will have a chance to respond to our claim, and then we will respond to that. There will be a hearing or two. We think it will take a year, maybe slightly more than a year, for a judge to make his decision. We think the case is pretty good. I think that the decision that the FDA made was hard to substantiate why they made it. We don't know what the factors where that led to that decision but we think it was harmful to the general public so we think there's a good chance that that decision will be reversed once again and no i don't think it'll have a meaningful impact on our costs or expenses for the year uh what was the other one again what was this other question i just wanted to ask about share repurchases what what's kind of impacting you know the evolution of your strategy there right so as you know we announced the 10 million dollar buyback we uh used 250 000 of it to date we expect we will be using uh the rest of it under the guidelines that we set forth in that buyback provision uh we we would have used more of it before but we got blocked out because of uh you know the timing of the uh of the announcement into earnings, among other, you know, material inside information. But, you know, we do expect to be using it more and buying back the shares. We think it's a great investment at this price.

And then just very quickly, can you comment on any near-term plans you have to advance clinical exploration of NR and Parkinson's disease at this time?

Well, we're waiting for the final manuscript and discussion with Tzulis. he's very bullish on this idea that uh it's a preventative before uh the standard care of l-dopa and the diagnosis of parkinson's and he has a fair amount of data to support that idea but at this point we're waiting to hear from him on that and there is anything more you want to contribute to that uh just like you said rob uh the manuscript uh be submitted for publication shortly here, so we can't divulge any of those details.

But we will be collaborating with Dr. DiSoulis, as I mentioned in my remarks, with a focus more toward looking at prevention.

Thank you.

Your next question comes from the line of Sean McGowan with Roth Capital. Please go ahead.

Thank you. Hi, guys. Hey, Sean. All right. In terms of looking for a little bit more color on the guidance, can you give us a sense of whether the phasing of the revenue growth in 26 is expected to be, you know, materially different from what we saw last year? You know, is it more front half or back half? And also a little bit more color on the gross margin guidance.

Where would you see that gross margin uptick coming from? you know the slight increase is it are we going to see slight improvements in consumer and ingredients or is it going to be more focused in one of one or the other of those segments hey sean uh was on here um so regards to the pacing of the sales we're expecting it to be more back loaded compared to previous years and with regards to gross margin we expect a slight improvement But it's not, it's not, it's driven by, you know, supply chain efficiencies and also the changing of the product mix. You know, we're seeing our 1,000 milligram skew perform well, and e-commerce is also performing well.

Okay, thanks. And similarly, looking for color of the, does your sales and marketing guidance anticipate the kind of step up in brand marketing that you referred to earlier? You know, is that, would that be additional? I think Rob said you might see some additional promotion, I mean, advertising, right? Is that anticipated in that already?

It's not anticipated in that. It would be an additional.

Okay. Thank you. Thank you.

That concludes our question and answer session. I will now turn the call back over to Lauren for closing remarks.

Thank you, Tiffany. There will be a replay of this call beginning at 7.30 p.m. Eastern time today. The replay number is 1-800-770-2030, and the replay ID is 858-4242. Thank you, everyone, for joining us today and for your continued support of NIAGEN Biophys.

Ladies and gentlemen, this concludes today's call. Thank you all for joining. You may now disconnect.
