Dan Goldberger, CEO

Thank you, Nicole. Hello everybody, and thank you for joining us on today's call. We are thrilled to report another record revenue quarter with sales of $2.8 million for the period ended March 31, 2023, a 46% increase over the prior year. Gross margins expanded nicely to 84% for the first quarter of 2023. Our prescription headache business continues to grow worldwide. We launched two new non-prescription product lines in late 2022: Truvaga as a direct-to-consumer wellness brand and TAC-STIM for human performance for our active duty military personnel. Both new products exceeded our expectations in the first quarter and are driving excitement about the future. Truvaga is currently available exclusively through our e-commerce platform @truvaga.com, and we are positioning Truvaga as a direct-to-consumer wellness product for stress, mental acuity, and sleep. No prescription is required for this category. Truvaga recorded net sales of $147,000 in the first quarter of 2023. Based on this initial success, we are accelerating our marketing investments and raising our internal expectations for the product line. So far this year, our revenue return on advertising spend, what the industry calls a media efficiency ratio or MER, has been greater than 2.0. We're carefully monitoring return rates as well, which have been below 10% so far this year. We believe that the Truvaga business can scale nicely if we can maintain or improve these metrics as we move through the year. TAC-STIM for human performance is being sold to select Air Force and Army Special Forces units for accelerated training, sustained attention, reduced fatigue, and improved mood, without a prescription as defined by the Air Force Research Laboratory or AFRL. We recorded $88,000 of TAC-STIM revenue in the first quarter of 2023, and I'm encouraged by the growing sales funnel for this product. In parallel, we're developing a second-generation product known internally as TAC-STIM 2.0 in collaboration with AFRL, and I expect to deliver prototypes to Wright Patterson Air Force Base for evaluation later this summer. Note that revenue growth for this product line is likely to be lumpy as active duty units purchase in bulk for pilot deployment. Turning now to our prescription headache business. The VA DoD hospital channel continues to be our largest customer. You'll recall that our gammaCore prescription therapy is free to patients covered by Veterans Administration benefits, representing about 10 million covered lives. Sales in the VA DoD channel grew 38% from $1,240,000 in Q1 2022 to $1,705,000 in the first quarter of 2023. 124 VA and DoD military treatment facilities have purchased prescription gammaCore products through March 31, 2023, as compared to 105 through March 31, 2022. US commercial sales of prescription gammaCore products grew 56% from $276,000 in Q1 2022 to $430,000 in the first quarter of 2023. While gammaCore is covered by certain Express Scripts and CVS Caremark benefit plans, most of our growth is coming from cash pay channels, including gCDirect and gConcierge. These channels have grown from 410 prescribers at the end of the first quarter of '22 to 1,834 at the end of the first quarter of 2023. We added 506 new prescribers during the first quarter of 2023, and our prescriber numbers continue to show strong growth through April 2023. We believe the increase in prescribers could be a leading indicator of future growth. Last year, we announced a distribution agreement with Joerns Healthcare, LLC, that we believe will add more than 12.5 million covered lives within a select managed care health system. The business model with Joerns will be similar to how we work with the VA hospital system. Joerns will handle adjudications, billing, and collections while electroCore will ship directly to patients and provide in-servicing and patient support. Our field sales team is responsible for educating clinicians within those managed care systems. We continue to work with Joerns on the implementation, and while we do not have any revenue in this channel in the first quarter of 2023, we've been notified that the first prescriptions were being processed through Joerns late last month. Revenue from channels outside the United States increased a healthy 34% to $410,000 in the first quarter of '23 as compared to $305,000 for the first quarter of 2022. Our U.S. revenue included $45,000 of licensing fees in Japan, while most of the balance was generated in the United Kingdom by prescription gammaCore sales funded by the National Health Service or NHS. Now, turning to our clinical progress, on April 26, 2023, we announced that the National Institute on Drug Abuse, NIDA, part of the National Institute of Health, NIH, has awarded Emory University and Georgia Institute of Technology a three-year, $6 million grant through the NIH helping to end addiction long-term or HEAL initiative to conduct a pivotal clinical trial of gammaCore nVNS for the treatment of opioid use disorder, OUD. A double-blind randomized sham-controlled study to be funded by the grant will recruit approximately 100 patients with OUD. The primary efficacy endpoint of the study will be peak difference in the subjective opioid withdrawal score between nVNS and sham treatment on day two and three of the initial withdrawal period. On April 24, '23, we announced that the Air Force Research Laboratories reported data from its study on the ability of our non-invasive Truvaga nerve stimulation to improve second language learning. The study was conducted at the Defense Language Institute in Monterey, California, the U.S. Department of Defense's Premier Language School. The study was supported by the Defense Advanced Research Project Agency, DARPA, within their targeted neuroplasticity training program. The study showed a significant positive effect of nVNS over sham on language recall. Participants receiving our treatment also showed significant increases in energy and focus. Over the course of each training session, on March 23, '23, we announced the publication of a paper entitled Non-Invasive Vagus Nerve Stimulation Improves Brain Lesion Volume and Neurobehavioral Outcomes in a Rat Model of Traumatic Brain Injury. In the Peer Review Journal of Neurotrauma, the control group showed significant deficits, but all of these deficits were reduced in the high-dose nVNS group. Additional work on the potential benefits of nVNS on TBI will be funded by an exploratory development research grant and R21 from the National Institute of Neurological Disorders and Stroke. We will continue to provide updates about our pipeline and other opportunities. Now, I'll turn the call over to Brian for a review of our financials and other guidance items.

Brian Posner, CFO

Thank you, Dan. Where the quarter ended March 31, 2023, electroCore recorded net sales of $2.8 million compared to $1.9 million during the same period of 2022, which represents an approximately 46% increase over the prior year. The increase of $881,000 is due to an increase in net sales across all major channels. Gross profits for the first quarter of 2023 were $2.3 million as compared to $1.5 million for the first quarter of 2022. Gross margin for the first quarter of 2023 was 84% compared to 81% in the first quarter of 2022. Total operating expenses in the first quarter of 2023 were approximately $8.5 million as compared to $7.1 million in the first quarter of 2022. Research and development expense in the first quarter of 2023 was $1.8 million as compared to $934,000 in the first quarter of 2022. This increase was primarily due to targeted investments to support the future iterations of our therapy delivery platform, including the use of our intellectual property around the delivery of smartphone integrated and smartphone connected, Non-Invasive therapy. Selling, general and administrative expense for the first quarter 2023 was $6.7 million as compared to $6.2 million in the first quarter of 2022. The increase was driven by severance charges of $332,000, as well as continued targeted investments in sales and marketing to support our commercial efforts offset by decreases in insurance and stock-based compensation expense. GAAP net loss in the first quarter of 2023 was $5.9 million compared to the $5.6 million net loss in the first quarter of 2022. Adjusted EBITDA net loss in the first quarter of 2023 was $5.1 million as compared to a net loss of $4.6 million in the first quarter of 2022. A reconciliation of GAAP net loss to non-GAAP adjusted EBITDA net loss has been provided in the financial statement tables included in today's press release. Net cash used in operating activities in the quarter ended in March 31, 2023, was approximately $5.9 million as compared to $4.8 million in the first quarter of 2022. This increase is primarily due to our investment and product evolution expenditures. We expect the investment level in R&D to begin tapering off for the remainder of the year. Total liabilities decreased from $7.7 million as of December 31, 2022, to $6.5 million as of March 31, 2023, contributing to the $5.9 million of net cash used in operating activities in the first quarter of 2023. Cash, cash equivalents and restricted cash at March 31, 2023, totaled approximately $12.2 million as compared to approximately $18 million as of December 31, 2022. Looking ahead for the full year 2023, we are reiterating our net revenue guidance of $14 million to $15 million, representing more than 60% growth over 2022. We believe that our prescription headache channels will continue growing by more than 50% to at least $12 million for the full year, and revenue from new products in the Truvaga and TAC-STIM brands could be more than $2 million for the full year. We expect net cash usage in the remainder of 2023 to be below the average quarter of the net cash usage in 2022. Net cash usage will decrease as revenues increase. We complete the development of new products and continue to rationalize other operating expenses. Therefore, we expect our net cash usage to decrease significantly as we progress through the year.

Dan Goldberger, CEO

Thank you, Brian. I'm very pleased with our first quarter 2023 operating results, and we are increasingly enthusiastic about the company's long-term prospects, especially in our two new product lines, Truvaga and TAC-STIM. Continued investment in our cash pay and covered business models have greatly expanded the prescription gammaCore therapy market. As reflected by the continued revenue growth, number of facilities and number of prescribers realized in the first quarter of 2023. Truvaga has tremendous potential as a direct-to-consumer wellness offering; we've started with an e-commerce business model, which will be the focus this year, and I look forward to launching a next-generation app-enabled product platform next year. We believe our metrics are trending in the right direction, and we will continue to adjust our investments in all of our commercial channels as the year progresses. TAC-STIM 2.0 is a next-generation human performance product being financed in part by the Air Force Special Forces through their boost program. It could accelerate the adoption of nVNS for human performance among our active duty military in the coming years. A pipeline of interest from different branches of the military continues to develop for our TAC-STIM product, which may result in expanded adoption in future quarters. Demand for our prescription gammaCore therapy and the VA DoD channel continues to grow based on clinical performance and our increased presence in the field. We now have about 45 straight commission sales agents, or 1099 reps in the field, managed by our small team of territory business managers and supported by our customer experience team. Note that our sales and marketing expense increased by $300,000 from $2.4 million in the first quarter of 2022 to $2.7 million in the first quarter of 2023. While sales grew almost $900,000 signaling that there may be real leverage opportunities in the P&L, if revenue increases over time. The timing of certain disbursements led to a substantial increase in cash used in operations in the first quarter, as Brian explained. Our R&D spend on new products likely peaked during the quarter, and we had one-time expenses around the special meeting of shareholders, reverse split, and severance costs. Quarterly cash usage is expected to decline as we go through the year due to anticipated revenue growth. Gross margins greater than 80%, declining R&D investments, and our intention to maintain discipline around operating expenses. Further out, we're working towards establishing additional indications for prescription gammaCore to treat post-traumatic stress disorder and/or opioid use disorder. Look for new product launches in 2024, featuring our app-enabled technology that can provide digital health solutions. That product platform will be launched in headache, wellness, and human performance as we ramp up our supply chain. We see many potential growth drivers for the remainder of 2023 and beyond, including continued growth in our U.S. prescription headache business in both the VA DoD and commercial channels. Further development of the Truvaga product for wellness, mental acuity, and sleep driven by increased direct-to-consumer marketing efforts. Further development of the TAC-STIM brand for human performance in the active duty military and beyond. Our app-enabled new product platform that will facilitate consumer-facing digital health solutions and unlock new business models and prescription gammaCore label extensions into PTSD and/or OUD in 2024 and 2025. Finally, in February 2023, we implemented a one-for-fifteen reverse split and regained compliance with NASDAQ listing requirements on March 6, 2023. We've been comfortably above any lifting requirements since effectuating the reverse split. This time I'll turn the call over to the operator. Operator, please open the line for questions.

Operator, Operator

Thank you. Our first question comes from Jess Cohen with Ladenburg Paulman. Please go ahead.

Unidentified Analyst, Analyst

Hey, this is actually Destiny on for Jeff. Thank you for taking our questions. I guess what I'd like to start with is actually the VA and DoD channels. You now have 324, if I heard correctly, facilities and 45 reps.

Dan Goldberger, CEO

124.

Unidentified Analyst, Analyst

Okay. Got it. Got it, got it. So can you talk a little bit more about the growth there and now that you have the 45 reps, how you kind of see it growing throughout the balance of the year and then obviously beyond.

Dan Goldberger, CEO

Yep. So, thanks for the opportunity Destiny. The VA hospitals we have basically two tactics. The first is opening new customers, new VA hospitals that haven't ordered from us before. And the second is taking care of our existing customers and going deeper within those existing customers. Both of those tasks at the end of the day still require feet on the street. We just haven't found a way to get these kinds of hospital-based sales without showing up and showing up reliably. And that's where the straight commission sales agents I call them really allow us to increase the activity. Many of us at the home office, our medical affairs team and our territory business managers get involved in targeting specific new facilities to open up. And then once we have opened them up, we rely on the local sales agents as well as our customer experience team to follow through. This is one of those areas where success begets success, and more and more our sales agents, as they're doing better and their network of colleagues who are also in the neighborhood hear about their success. We're looking at some acceleration in our ability to reach new facilities as well as to go deeper within existing facilities. And just to be clear, the sales agents are all variable expense. There's no fixed expense associated with them.

Unidentified Analyst, Analyst

Got it. Okay. And you mentioned having 45 representatives. Has that changed at all since last time?

Dan Goldberger, CEO

Yeah. That's a dramatic increase from where we were at the end of last year we were just starting to put together our network of 1099 reps as we exited last year.

Unidentified Analyst, Analyst

Perfect. Okay. That's really encouraging. Thank you. And then perhaps I'll go over to TAC-STIM 2.0 as you're calling it. Can you just talk a little bit about some of the advancements you're making or some differences between the TAC-STIM device now and 2.0? And then yeah, well, let's start with that and then I'll have a follow up.

Dan Goldberger, CEO

Sure. So Air Force Research Laboratories has been working closely with us to develop a mil-spec rugged reliable version of our handheld personal use Truvaga's nerve stimulator. I actually had the great pleasure of showing some prototypes to special forces operators in Florida just last week, and they're getting very excited about this next-generation configuration because it's going to be far more useful to them in the field. As far as timing, we're going to have to stay quiet about the timing for when that product is going to launch, but we're very excited about it. And, maybe more importantly, the special forces operators are excited about it.

Unidentified Analyst, Analyst

Absolutely. Okay, great. Thank you. And then I want to bounce over to Truvaga. I was wondering if you could talk a little bit about your demographic data there, given that this is an over-the-counter type product that's pretty readily available. Are you seeing a huge change or difference in demographic between your gamma and the Truvaga?

Dan Goldberger, CEO

So most of our U.S. gammaCore sales are through the VA hospital system, and that's a very different demographic. But on our commercial side, I think the demographic skews younger. But still, the Truvaga personas that we're currently targeting with our media spend and our internet search and social media spend is younger and more affluent. But it's really small numbers at this point, and I don't want to draw too many conclusions from what are really small numbers by the grand scheme of things.

Unidentified Analyst, Analyst

Okay. Got it. And then Brian, I just have a couple for you. The gross margin expansion, is this kind of a level we should expect to see going forward? And the driver is volume or channels or both? Yeah, I guess let's start with that. I get ahead of myself.

Brian Posner, CFO

Yeah. No, that's okay. I'll try to keep up with you. No, we've been consistently in the eighties for the past year. We had some cleanup on the balance sheet in Q4, so we were down to 75%, but without that cleanup, we would've been in right around where we finished Q1. So I think that's for right now that in the eighties is a safe place to assume. I think it's a combination of increased revenue, that we absorb more labor and overhead. We continue to also sell more and more longer-duration products, which also is accretive to gross margin as well.

Unidentified Analyst, Analyst

Okay. Got it. Thank you. And then last one, I promise, in terms of a greater investment in marketing, what kind of investment are you looking at maybe on a percentage basis going forward?

Brian Posner, CFO

Yeah, so I talked a little bit about the growth in our sales and marketing expense compared to the growth in revenue. Back to the envelope, our sales and marketing expense grew at sort of less than 30% of revenue. So I think that might be a good way to think about how we're going to be reinvesting in sales and marketing to grow that revenue line.

Unidentified Analyst, Analyst

Okay. Perfect. Well, that does it for me. Thank you for taking my many questions. I'll hop back in queue.

Operator, Operator

Next question comes from John Vandermosten, Zacks SCR. Please go ahead.

John Vandermosten, Analyst

Alright, thank you. And hello, Dan and Brian. You guys have had a lot of great press releases on just the wide profile of the device and what it can do. And, language learning is just something else that I haven't even thought about. But, in our research, we've seen a lot of other areas that you've talked about also as well, and it seems to have a safety profile on kind of the benefits of exercise, right? But without the effort, and you also have opened up a channel that doesn't rely on the FDA to distribute the product. And I'm wondering, how can you leverage that and also get more eyes on the product and what it can do to really leverage that Truvaga channel that you have?

Dan Goldberger, CEO

Well, we're, this is early days for us, John, but you're absolutely right. If we do this correctly, the direct-to-consumer wellness for stress, mental acuity, and sleep is going to draw attention to the fundamental benefits of vagus nerve stimulation, and should have carryover to our prescription strength gammaCore brand and vice versa. And then all of the exciting work that Army Special Forces and Air Force Special Forces are doing that I can't talk about yet. And I'm really looking forward to the day that we can start a campaign that's, for example, as used by Army Special Forces. So all three brands, if we do this correctly, are going to reinforce and build on each other. The other, yet another opportunity for us, and we haven't talked about it too much yet is the relatively young Truvaga nerve society. It's a professional academic society, which is really focused on all of the benefits and methods of operation of the vagus nerve starting from holistic approaches, including implants and of course non-invasive and minimally invasive approaches. But that society is becoming a forum for broad-based discussion by healthcare professionals, by neuroscientists, and ultimately I think by the lay public as well.

John Vandermosten, Analyst

Okay. And we, as we're still in the early stages of Truvaga, with very, very low revenues relative to some of your other businesses. But I guess, do you prefer, on a margin basis, do you prefer a dollar revenues from Truvaga or the VA kind of NHS source?

Dan Goldberger, CEO

You know, all of these, all three of the brands right now are in that low 80% gross margins. So they all help each other, and because we're still a very small business, revenue in general helps us spread the fixed expenses of the company, the public company expenses, rents, insurance.

John Vandermosten, Analyst

So it sounds like Truvaga right now is kind of on par with the other ones as it grows, the attractiveness might increase, just leveraging kind of the fixed efforts. Yeah?

Dan Goldberger, CEO

Absolutely. Truvaga, absolutely.

John Vandermosten, Analyst

Okay. Yeah, yeah, no, that's really helpful. And wanted to look at the NIDA grant. How is that going to flow through your income statement? You mentioned it was a three-year study…

Dan Goldberger, CEO

It's well, that…

John Vandermosten, Analyst

Oh, I'm sorry, Dan,…

Dan Goldberger, CEO

The NIDA grant is to Emory University and the VA, the Atlanta VA Hospital. All of that money is going to those entities to execute the pivotal trial. So maybe the right way to think about it is it's an expense offset because that pivotal trial will become the foundation of a 510(k) submission and ultimately a label extension to treat the symptoms of withdrawal from opioid use. So it's money that we don't have to spend in order to get that additional indication in the future.

John Vandermosten, Analyst

Okay. And you, it was a three-year study. What was the start date on that, or anticipated start date?

Dan Goldberger, CEO

So, the trial will start in the coming months. We're optimistic that they will complete enrollment towards the end of 2024 in which case we can execute on the regulatory process in 2025.

John Vandermosten, Analyst

Great. And last thing, you had a press release announcing that you received the annual license fee from them. Are there any milestones in the near term or medium term that we should look out for to help us predict when royalty revenues may come?

Dan Goldberger, CEO

We are recognizing license revenues quarterly, and they are making payments each quarter. I believe what you're really wondering is when this will convert into product sales. That likely remains within the planning timeframe. Our colleagues are collaborating with the Japanese Ministry of Health. They are advocating for the Ministry to accept the pivotal data gathered in the United States, but there is still a strong possibility that they will need to conduct at least a small pivotal trial within the country, which will take some time.

John Vandermosten, Analyst

Got it. Alright, Dan, thank you so much. And Brian, thank you as well.

Dan Goldberger, CEO

Thanks, John. Appreciate your support.

Operator, Operator

Next question comes from Ramakanth Swayampakula with H.C. Wainwright. Please go ahead.

Ramakanth Swayampakula, Analyst

Thank you. Good afternoon. Dan and Brian, this is obviously we have discussed quite a few, quite a few interesting pieces of the company. A couple of things that I would like to understand a little bit more is that on the commercial business, you know I believe you stated that there are about 1,834 prescribers are approximately five and six new additions, which is quite a decent number in terms of prescribers added. How, how does that translate to revenue? And you said you're kind of thinking of them as a lead-in indicator. So I'm just trying to understand like how, how do you, how are you coming to that conclusion, and when you say lead-in, what is the lag time we are thinking of from them coming on board, to getting scripts to return on a regular basis?

Dan Goldberger, CEO

Yeah, so, so those that cohort of 500 that we engaged in the first quarter, our metric is that we filled at least one prescription in order for that prescriber to be counted as a new prescriber. So they're already generating revenue. There are two metrics there. The first is how many of those are new prescriptions and then how many are refill prescriptions? To an earlier question, Brian said something about product mix and refill prescriptions are higher margin for us, but we need the new prescriptions in order to build the installed base, if you will, of happy patients that are going to come back for refill prescriptions. So there are two ways that this business builds on itself. The first is that once we've engaged a prescriber, if their patients have a good experience, they come back and prescribe for more of their patients, and getting patients to stay on therapy and come back for refill prescriptions.

Ramakanth Swayampakula, Analyst

Very good. And then, when you made your statements about John's healthcare you are also suggesting that this could potentially become something close to what is doing for you with, so for that really to happen what needs to get done? I know you, we are just very, very early stages. You just said the first set of prescriptions have been processed in late April. But I'm just trying to understand how would it become meaningful or like how long could that take to become meaningful?

Dan Goldberger, CEO

Yeah, so, the short answer is that we think it's going to be meaningful revenue as we exit this year. As a practical matter, these first prescriptions are bumping their way through the Kaiser system first, and then they get to Joerns. Joerns has to identify the particular patient, figure out which benefit plan they're on, and figure out where that individual is with respect to copays and deductibles. It's called adjudicating the prescription. Then, they have to collect that copay from the patient before we can dispense to the patient. Each one of those steps has to be sorted out in the bureaucracy, but once it's sorted out, it should start to become far more systematic and scalable. As the bureaucracy starts to work smoothly, we're going to take our same field sales force that's calling on the VA hospitals to start calling on the Kaiser facilities to engage prescribers to scale that business. It's got a lot of the same characteristics as the VA hospital business. So I'm very optimistic that it's always going to take longer than I want, but I'm optimistic that as we roll into 2024 fundamentally we'll have access to another 10 million covered lives.

Ramakanth Swayampakula, Analyst

Very good. Then this is a kind of a two-part question. So when we think about Umcor Truvaga taxed him, TAC-STIM 2.0 how, how, what is the margin contribution from, you know is the margin contribution different from each one of these things? And then also in terms of the pricing, how different is it for each one of these?

Dan Goldberger, CEO

So it, it, it's a very good question. The numbers for our new brands are still very small. So the margin profile is going to evolve. The Truvaga product that we're currently selling is on the internet for $300 for a first transaction. So that, that's kind of the price point. The TAC-STIM is right now is very limited distribution to certain units of special forces. Each one of those transactions has its own pricing profile. So right now, it's not that it's complicated, but we're not sharing very much pricing information publicly until these lines of business are substantially larger.

Ramakanth Swayampakula, Analyst

Okay. So the last question from me is, again, from among these four devices, or brand lines, is the technology any different or it's all the same except that it's packaged differently for different uses?

Dan Goldberger, CEO

So the way that I like to describe it is that gammaCore is our prescription-strength product offering. Truvaga is our direct-to-consumer wellness product and has the same, exactly the same safety profile but is not as energetic as the prescription strength. You know, we may have talked about it, but I can go to the corner store and get 200 milligrams of ibuprofen under the Advil brand in pretty much any store you want to. But I can also go to my doctor or dentist and get a prescription for Motrin, which is 800 milligrams of ibuprofen. There’s prescription strength ibuprofen, and then there's the direct-to-consumer over-the-counter strength. And that's how we're trying to differentiate those product lines.

Ramakanth Swayampakula, Analyst

Okay. So Truvaga is not going to teach me a different language, or it'll have a tougher time.

Dan Goldberger, CEO

No, No.

Ramakanth Swayampakula, Analyst

Thank you. Thanks for taking my questions.

Operator, Operator

Next question comes from Kemp Dolliver with Brookline Capital Markets. Please go ahead.

Kemp Dolliver, Analyst

Hi, thank you, and good afternoon. Just a couple of questions. When you talk about R&D spend tapering from Q1's level, how much of a reduction should we think about?

Brian Posner, CFO

Yeah, we're... oh, go ahead Dan.

Dan Goldberger, CEO

Go ahead, Brian.

Brian Posner, CFO

So we were about $1.8 million this quarter. I don't think we're going to give specific, you know, dollar guidance on the call, but we expect by the end of the year that number will go down significantly.

Kemp Dolliver, Analyst

Okay. Dan, were you going to give away the goods?

Dan Goldberger, CEO

Nope. I was going to be even vaguer than him, than Brian.

Kemp Dolliver, Analyst

Okay. Alright. Fair enough.

Dan Goldberger, CEO

He wasn't going to use the word significantly probably.

Kemp Dolliver, Analyst

Okay. Thank you. And you know, Brian, I was looking at the 10-Q quickly and, you know, there was a pretty significant reduction in the long-term inventory number. And can you talk about the dynamic there? And when we raised…

Brian Posner, CFO

Yeah, it's a great question. I don't think there's a right now a write-down risk, you know, but it's more what do we expect to sell that we have in inventory in the next year from the date of the balance sheet? So the good news is the current's going up because one, we're selling, we're selling inventory, and two, we project our revenue to the left, as you can see to our guidance. Eventually we won't have long-term inventory; we'll be more traditional, just, it'll be a current asset. But that's good news. The more that goes into current from long-term means we're confident about selling that inventory in the next 12-month period.

And, and look, I'll pile on that. I think Brian and his team have done a great job of monetizing that inventory that we inherited several years ago. Kudos.

Next question comes from Nick Sherwood with Maxim Group. Please go ahead.

Nick Sherwood, Analyst

Good afternoon, this is Nick Sherwood speaking for Anthony ETT of Maxim Group, LLC. Can you get into a little more detail on what's driving the traffic for the e-commerce platform? Truvaga? Is that a lot of digital marketing or are you seeing some organic growth just from word of mouth that comes from the VA channel?

Dan Goldberger, CEO

Yeah, so there is some organic, there's some early adopter. Most of our spend in the first quarter was around paid search. We've started to open up social media channels, and I think we just went live on TikTok. We're starting to learn about influencers, and we're doing a lot of A/B testing on these different digital marketing techniques. So we're pretty excited. As I said in the script, it far exceeded our expectations in the first quarter, and now we're feeling more and more comfortable about increasing the spend and maintaining that return on advertising spend ratios. It should scale nicely.

Nick Sherwood, Analyst

Okay, perfect. And I think that's all the questions that I have. So thank you for your time. Great. Appreciate your interest.

There are no further questions at this time. I would like to turn the floor back over to Dan Goldberger for closing comments. Please go ahead.

Dan Goldberger, CEO

Oh, thank you operator. And we appreciate everybody joining today's call. Lots of good questions. I hope we were helpful in our answers. I want to give special thanks to all of our employees and our new cohort of sales agents who are working tirelessly to deliver this amazing therapy to patients. I also want to thank the healthcare professionals and their patients for their loyal support of our gammaCore therapy. We greatly appreciate support from Air Force Research Laboratories and the National Institute on Drug Abuse for supporting our new product initiatives and label expansions. We've made a tremendous amount of progress and would not have been possible without all of you and your unwavering support. So thank you and have a good evening.
