Thank you, Peter. Good afternoon, everyone, and thanks for taking the time to join us on today's call. In the second quarter of 2024, we delivered strong net sales growth from our key growth drivers, Qelbree and GOCOVRI and continue to advance our product pipeline, including SPN-817 for treatment-resistant seizures and SPN-820 or depression. Total revenues, excluding Trokendi XR and Oxtellar XR increased 32% in the second quarter. Driving this growth was Qelbree’s strong performance with 26% growth in prescriptions as reported by IQVIA and 92% growth in net sales. Prescriptions reached an all-time quarterly high of 184,342 and net sales were $59 million. In the first 6 months of 2024, Qelbree prescriptions grew by 28% compared to the same period last year, and net sales were $105 million, representing an 84% growth over the same period last year. Growth in net sales of Qelbree in the second quarter of 2024 benefited from both prescription growth and gross to net improvements compared to the same period last year. Gross to net deductions during the second quarter of this year were below our target range of 50% to 55%. We saw more favorable product returns trend with initial launch phases experiencing lower return rates than assuming and continued lower copay deductions in the quarter. As a result, for the remainder of 2024, we expect the gross to net for Qelbree to be in the 45% to 50% range, with fluctuations that we would typically expect on a quarterly basis. During the second quarter, Qelbree also expanded its base of prescribers ending the quarter with approximately 28,326 prescribers, up from 27,138 in the first quarter of this year. Prescriptions from adult patients now account for approximately 32% of Qelbree’s total prescriptions. Switching now to GOCOVRI, net sales increased to $32 million in…

Thank you, Jack. Good afternoon, everyone. As I review our second quarter 2024 results, please refer to today's press release and 10-Q that were filed earlier today. Total revenue for the second quarter of 2024 was $168.3 million compared to $135.5 million in the same quarter last year. Total revenue in the second quarter of 2024 was comprised of net product sales of $162.5 million and royalty, licensing and other revenues of $5.8 million. The increase in net product sales was primarily due to the increase in net product sales of our growth products, Calgary and GOCOVRI as well as Oxtellar XR. Excluding net product sales of Trokendi XR and Oxtellar XR, total revenues for the second quarter of 2024 increased 32% compared to the same quarter last year. For the second quarter of 2024, combined R&D and SG&A expenses were $112.1 million as compared to $111.2 million for the same quarter last year. This slight increase was primarily due to R&D spend associated with clinical programs for SPN-817 and SPN-820 as we continue to progress our pipeline. Operating earnings on a GAAP basis for the second quarter of 2024 was $22.6 million as compared to an operating loss of $17.6 million for the same quarter last year. Income tax expense in the second quarter of 2024 was $6.4 million. GAAP net earnings was $19.9 million for the second quarter of 2024 or $0.36 per diluted share compared to a GAAP net loss of $831,000 or $0.02 loss per diluted share in the same quarter last year. On a non-GAAP basis, which excludes amortization and intangibles, share-based compensation, contingent consideration and depreciation, adjusted operating earnings for the second quarter of 2024 was $45.5 million compared to $10 million in the same quarter last year. Total revenues for the six months…

Thank you. At this time, we will now conduct a question-and-answer session. [Operator Instructions] Our first question comes from Andrew Tsai of Jefferies. Your line is now open.

Hi, good afternoon. Congrats on a nice quarter. Thanks for taking my questions. The first one is on SPN-830, the apomorphine pump. Congrats on resubmitting that. Just wanted to gauge your level of confidence it will be approved this time. It's kind of interesting since we know the competitor also received the CR recently. So maybe talk about your level of confidence about this. Thanks.

Yes, sure. A couple of things. I mean the first one we've got a CRL, I tried to give you an example. It probably was a few pages. This time we got the CRL that was maybe a half a page give or take, just to make an example of the number of issues we're dealing with. So certainly, with this resubmission, the number of issues we're dealing with was much lower number of items and issues that we have to address. Second thing is we did have a meeting with the FDA before the resubmission to make sure we have the fullest level of confidence before we resubmit. So, we feel pretty good about the filing right now and our chances of getting approved. Of course, as I mentioned in our remarks, what we're still not sure about is whether it will be a Class I or Class II submission, but hopefully, we'll have that piece of information in the next few weeks when they have behaved accepts the filing and assigns a PDUFA date for their review.

Makes sense. Thanks. And shifting to 817, we're going to have the full Phase 2a data cut later this year. Can you remind us, I think 19 of 41 patients completed the maintenance period, how many more patients do you think will be completing that maintenance period? And how many more specifically at the 3 to 4 milligram dose, the high doses?

Yes. At that time, back in May, when we reported the interim results, in addition to the 19, we had about seven or eight, if I remember the number directly or patients were still in the study at various stages. So we would expect when we report the full results to have at least another maybe, I don't know, five, six, depending on how many discontinue or how many stay in all the stages of the study. We should have a good handful of people in addition to the 19 that we will report on. So that's -- that will complete the initial portion of the study just to clarify. The second portion was the extension, which we talked about back in May, where we are going to test a couple of strategies. One of them is adding an antiemetic where we try to address the nausea and so forth. So, that portion of the study, it has already started, but we won't have data in the fourth quarter or before year-end for this year. Just to clarify that. There are two different pieces of the study, the initial one, which we will report on, but the extension, which we added in May, we will not have the data to report on that.

Okay. And then last one is on 820. The depression asset you're having pulsatile data in 40 patients with MDD later this year. Can you just remind us how long the study is? And what kind of made or HAMD efficacy benefit you want to see at the end of the study, what would be positive data to you and why? Thank you.

Yes. I mean this is a short study. I think it's about 10-days treatment. So it's not a very long study. It is open label, about 40 patients that we are targeting. So, we think we have a very good chance we will be able to report before year-end. And as far as the number of -- or the reduction in the scales and what would we expect, of course, the larger the better, especially than it is open label, so we would hope to see certainly a large improvement on MADRS versus if it were the placebo controlled.

Thanks again.

Thank you. Our next question comes from David Amsellem of Piper Sandler. Your line is now open.

Thanks. A couple of questions on Calgary. So with the back-to-school season coming up, help us understand your expectations for acceleration in volumes, particularly with the different gross to net framework that you've been talking about? And also in the context of, I believe, last back-to-school season, the Rx growth was -- or acceleration was a bit muted. So help us understand how you're thinking about this year's back-to-school season? That's number one. And then number two, is the -- how much of the growth through the back half of the year is the year-on-year growth is volumes? And how much of it is improvement in gross-to-net? And just help us better understand, how we should be thinking about Calgary -- in other words, what I guess, I'm trying to get at is, is Calbury a volume growth product going forward? Or is a lot of the growth that's being captured is really just a function of improved economics. So that's just been applied to this year, but also how you're thinking about the product beyond this year? Thanks.

Yeah. I mean as an overall comment on the prescription growth of Calgary, I mean, as we mentioned in the first half, we grew by about 28%. So we continue to expect to have robust growth in prescriptions versus last year. As far as specifically the back-to-school seasons, you're absolutely right, last year, overall, the market, the ADHD market, there was a much softer back-to-school season than normally we would see. And actually, looking at the year-to-date ADHD market growth this year, so far, it's up 8% in 2024 year-to-date in the first half of this year versus 2023. And if you might remember, the ADHD market grew only by 3% in 2023 in total. So this year already is showing a recovery in the market, in the overall market in general, at least in the first half of 2024 at a much higher growth rate than last year. So I'm hoping that the back-to-school season would be back to what normal growth would be versus what happened in 2023. I mean in 2023, we actually saw some decline actually in the ADHD market. With the measurement that we talked about it back then, which was June through September was not necessarily a calendar quarter to get a better feel for what happened in the back-to-school, while Gocovri continued to grow last year, and it grew by about 19% in the back-to-school season. So I'm hoping that the market does better. And, of course, that means we will also do better than we did last year as far as the growth. But the short answer to your question is the growth in Calgary is not just the improvement in gross-to-net. Certainly, we continue to have robust growth. I mean, we're already in year four as far as the launch of this product, and we're still delivering 20% plus growth in prescriptions. And from a penetration perspective, we still have a lot of room to go here as far as the potential of this product and its penetration in the market; adult and pediatric at the same time. Hopefully, that should answer all the question.

Yes. And if I just may sneak in a quick follow-up. The gross-to-net, I mean, it's been below 50%, I mean, which is better than what you had cited as a target in the past. I mean is that 45% to 50% and just to be clear, that's your view of steady-state gross-to-net over the long-term for the product? And maybe I'll ask it differently, is there room for even further improvement?

Yes, I mean, what I referred to in my prepared remarks, which was the issue of return, just to explain it a little bit more. Typically, when you first launch a product, you make an assumption on how much of these initial batches that you ship out, how much of those could potentially come back at some point from a return perspective. And you book it, you enter in your books as far as potential liability, accruals, what have you on these returns. And then as time goes on, these batches, they will either be consumed or they expire because time goes on and they have a certain fixed expiration date. So as they approach or go beyond the expiration date, basically they're not going to be returned anymore. Or if you do have much lower experience from a return perspective versus the initial assumption, that's when you can take back some of that. So these are the things that could potentially continue that way. I mean, there is a possibility we continue to benefit from that trend in the next quarter or so. So it may not be at one time, but we can only see that when we get the data every quarter. And therefore, back to your question on an ongoing basis would the target be 45% to 50%? I should hope so. I mean, I should hope that next quarter gives us even more confidence. And in that case, we will emphasize or confirm that that probably is our long-term target versus the 50% to 55%.

Sure. That's helpful. Thank you.

Thank you. Our next question comes from Stacy Ku of TD Cowen. Your line is now open.

Wonderful. Thanks so much for taking our questions. What a great quarter for Qelbree and just a solid net value for prescription. So we have a few follow-ups. Just for Q1, can you just talk a little bit more about what approach you're trying to do to grab share in the back-to-school season? So just to clarify, you said the next quarter or so you could see a benefit in gross-to-net, but do you think any of these back-to-school plans could impact the gross to nets in Q3? So this is the first question. And then to ask the question a little bit differently, how do you think about your comfort with the $200 million and $220 million consensus rates for Qelbree that you've kind of commented on in the past? Could this be exceeded as we think about just the solid growth to net improvements? And then last question is on the adult growth. Talked about the 32% split, but is this driving the net pricing? Are you seeing kind of encouraging growth and how should we think about the remainder of the year, as you think about really trying to drive that adult launch as well? Thank you so much.

Yeah. On the first question as far as the back-to-school programs, I mean, it's fairly intense as far as the level of support that we will be going out with and the momentum that we will be building and are building actually as we speak right now in preparation for the back-to-school season. So we will put a lot of investment and effort behind this season, given the importance of the season for the whole year, for the brand in general. At the same time, we're not neglecting the adult sector -- again, a portion of the business, of course, in Q3, but the top priority is clearly children and pediatric because of the back-to-school. As far as the annual, so to speak, soft guidance or whichever way you want to describe it, the $200 million to $220 million. I mean, clearly, in the first six months, we did $14.5 million or $105 million, double that is 10%. And of course, you got to add some growth to it. So clearly, we feel comfortable with that range. Is it going to be a little bit closer to the upper range or hopefully, again, it all depends on the back-to-school season, which was a lot of what we've been talking about today, if the back-to-school season is really strong this year and not soft like it was last year. Maybe we will be closer to the upper end of that range on Qelbree. And then finally, in the first -- in this past quarter, in the second quarter, to give you an idea about our adult prescriptions of business grew by about 26%. The PPNR grew by about 22% to 23%. So we have put some more emphasis on the adult patient population in the second quarter as times. So we are experiencing a little bit more growth in adult. But again, on a quarter-to-quarter basis, as I mentioned earlier, or in previous calls, sometimes we on purpose shift the emphasis one quarter versus another depending on the seasonality and the importance of that specific patient population.

Very helpful. Thank you.

Thank you. The next question comes from Annabel Samimy of Stifel. Your line is now open.

Hi. Thanks for taking my question. And great quarter on Qelbree. I just want to put a finer point on the adult versus pediatric. To what extent is the adult population driving some of maybe the improved pricing? Obviously, they have higher doses, so potentially a higher price point. And given that that's where a good chunk of the growth was and some of your efforts had been lying in that area. Can you maybe share some of the feedback that you're getting from the adult population? Is this an area that you can continue to push? And is there any pushback from the adults in terms of whether they're favoring a stimulant versus a non-stimulant if they're still transitioning with lower doses than you expected, et cetera, et cetera. Just trying to understand why with the growth that you have, why it's still sitting at 32% of your total prescriptions and also with the efforts that you're making last quarter. Thanks.

Yeah. Regarding the price points and so forth, I'll just give you a couple of numbers. I mean, these are more gross numbers. But for the adult, I mean we estimate the average blended cost of prescription is around $600, $615. By comparison, it's around $525 for pediatrics. So there is about 15%, 17% difference between the price for description test versus adult. And then actually is obviously a result of the size of the prescription. So with anodes, you normally have 50 to 52 tablets per prescription or capsules for prescription with pediatric, it's more around the 44, 45 capsules per prescription. So these are some of the metrics. Obviously, it does change over time quarter-to-quarter, but that's where we are right now as far as the pediatric versus above. As far as the feedback on the adult patient population, I mean, very consistent, fairly consistent with the pediatric, about the product, its performance, clinical benefits, all of the above, the powerability and safety. I mean, very, very consistent across all patient populations with both of them showing the growth and acceptance of the product. And by no means, we have -- we are even anywhere close to saturation as far as our penetration rates, I mean, our market share and although very low. And we have a huge, huge opportunity here for us to continue to push the product. And again, as long as the product continues to perform, we see no reason for it to slow down and try to get a much higher market share penetration within the adult segment.

Got it. And maybe you can just share what your expectations are for the level of penetration you might have in that adult population in your -- either for the year or for the long-term outlook? Is this still going to be a 32% type of well, I mean is it going to account still for about 32% of your prescriptions? Or do you expect that number to continue to go up through the year?

Yeah. I mean we do expect it to go up eventually whether through this year or next quarter or the quarter end, but more on a long-term basis, definitely, we would expect and we certainly will be working pretty hard to get that portion to be a bigger part of the mix. So will Calgary end up being a 40% adult and 60% pediatric, where the market is pretty much 67% adult and 33% pediatric? For now, I mean, we are an un-stimulant anyway in general. So you are going to have some bias of the business being a little bit more pediatric than adult in general, generally speaking. But certainly, we are pushing pretty hard to get that 32% much higher as being part of the mix. And as far as they evolve in general, as I mentioned earlier, I mean, the satisfaction, the performance, everything is very similar to what we're seeing with the pediatric. So we see no reason, why we shouldn't be able to continue to grow within the adult market. At this point, our market share within the adult market is around 0.3% in pediatrics and the 2% give or takes. So we continue to look for the whole brand, Calgary. You might remember, we talked about somewhere between 4%, 5% market share or could be as high as 10% market share of the total ADHD market. So we clearly have a long way to go here with Calgary.

Okay. Got it. And if I can just ask a quick question on SPN-830, I guess this is several times now through the review process. Are there any indications from FDA on the breadth of the population that might be included in the label? I'm not sure if you ever got to that point where you got to label discussions, but is FDA considering a broader label? Or is it still mostly in the severe camp? Thanks.

Yeah. I mean at this point, it's really premature for us to make any comment on that, because we haven't gotten that far as well as discussions. So we really don't know at this point.

Okay. Great. Thank you.

Thank you.

Thank you. This concludes the question-and-answer session. I would now like to turn it back to Jack Khattar, for closing remarks.

In concluding our call this afternoon, we thank you for joining us to learn about our strong performance in the second quarter and the first half of this year. The company continues to execute remarkably well through a multiyear transition and the loss of exclusivity on two of its legacy products. The company has generated strong positive cash flows behind the strength of its portfolio, particularly our growth products and the efficiency of its operations. In addition, we are excited about our progress on the pipeline across several programs. These programs will be generating significant data over the next six to 12 months. Thanks again for joining us this afternoon. We look forward to updating you on our next call.

Thank you for your participation in today's conference. This does conclude our program. You may now disconnect.
