Supernus continues to execute well against its growth plan and had a strong and very active second quarter. In April, we launched ONAPGO the first and only subcutaneous apomorphine infusion device for the treatment of motor fluctuations in adults with advanced Parkinson’s disease. In June, we announced the acquisition of Sage Therapeutics, which closed on July 31. In addition, we generated strong operating results driven by the robust performance of Qelbree and GOCOVRI. The second quarter of 2025 represents a turning point for Supernus and the beginning of a new phase of accelerated growth. We consider the transition from Trokendi XR and Oxtellar XR to be substantially complete, as each product represented only 7% of total net sales in the second quarter, while our growth drivers, Qelbree, GOCOVRI, and ONAPGO, combined represented 73% of our total net sales. Moving forward with the addition of ZURZUVAE, our fourth growth driver, we expect Trokendi XR’s and Oxtellar XR’s share of our portfolio to be reduced even further. Starting with our first growth driver, Qelbree, the brand entered its fifth year on the market and had another robust performance with 23% growth in prescriptions, as reported by IQVIA, and 31% growth in net sales. Qelbree had another quarter expanding its base of prescribers, with approximately 36,000 prescribers in the second quarter of 2025, up by 23% compared to the same period last year. After posting 25% growth in IQVIA prescriptions in 2024 versus 2023, Qelbree continued to show steady, strong growth during the first half of 2025, with prescriptions increasing 23% compared to the same period in 2024. Qelbree’s 23% growth outpaced both the ADHD market, which grew by 9%, and the non-stimulant segment, which grew by 11%. In addition to growth in the pediatric business, Qelbree experienced high growth in the adult business, increasing 29% in the second quarter compared to last year. By the end of June 2025, the adult business had reached 35% of total Qelbree prescriptions compared to approximately 32% for the year 2024. Switching to our second growth driver, GOCOVRI continued its strong performance on the back of the momentum it had in the first quarter. Prescriptions for the second quarter of 2025 increased by 14%, and net sales increased by 16% compared to the same quarter last year. The number of prescribers reached a new high in the quarter to approximately 1,900 prescribers. In the first half of this year, GOCOVRI benefited from the Medicare redesign, and by June 2025, 97% of GOCOVRI Medicare prescriptions had a copay that was less than $25 compared to only 77% in 2024. The average GOCOVRI Medicare copay declined by 42% and 80% year- over- year for the first quarter and second quarter of 2025, respectively. Unlike previous years, patient retention rates held up this year despite the deductible resets. With a more robust patient base this year, we are uniquely positioned to continue growing the brand with new patients rather than having to recapture previous patients that may have discontinued due to the high beginning of the year deductibles. Moving to our third growth driver, ONAPGO, the launch is off to a terrific start, exceeding our expectations. We launched ONAPGO in April, utilizing our existing Parkinson’s disease salesforce and support network. Through the end of June, we have more than 750 patient enrollment forms submitted by more than 300 prescribers. Finally, regarding ZURZUVAE, our fourth growth driver, we are excited to have completed the acquisition of Sage Therapeutics, which represents a major step for Supernus in accelerating its mid-to-long-term revenue growth and cash flow. ZURZUVAE is a unique and well-differentiated product that is early in its launch and that provides further diversification for our revenue base. The product has been successfully launched by Sage and its partner Biogen in the U.S., with 2025 second quarter net revenues, as reported by Sage, reaching $23.2 million, up from $13.8 million, as reported by Sage in the first quarter of 2025, representing a 68% increase. We will be focused on integrating the business and working closely with our partners, Biogen and Shinobi, to ensure the continued success and growth of ZURZUVAE. Moving on to R&D, we are on track to initiate a follow-on phase II B multicellular randomized double-blind placebo control trial with SPN-820 in approximately 200 adults with major depressive disorder by the end of 2025. This study will examine the safety and tolerability of SPN-820 and its efficacy at a dose of 2,400 mg given intermittently twice per week as an adjunctive treatment to the current baseline antidepressant therapy. Our phase II B randomized double-blind placebo control study of 817 is ongoing with a targeted enrollment of approximately 258 adult patients with treatment-resistant focal seizures. This trial utilizes 3 mg and 4 mg twice daily doses. As we mentioned previously, we completed a pharmacokinetic study of two oral formulations of SPN-443 in healthy adults. Both formulations of SPN-443 showed adequate bioavailability and were well tolerated. SPN-443 is our new stimulant-like product candidate for ADHD and other CNS disorders. The company expects to disclose a lead indication for the product candidate by the end of 2025. Finally, despite the completion of the recent acquisition of Sage Therapeutics, corporate development will continue to be a top priority for us as we look for additional strategic opportunities to further strengthen our future growth through additional revenue-generating products or late-stage pipeline product candidates. With that, I will now turn the call over to Tim Dec. Thank you, Jack. Good afternoon, everyone. As I review our second quarter 2025 results, please refer to today's press release and 10-Q that were filed earlier today. Total revenue for the second quarter of 2025 was $165 million compared to $168 million in the same quarter last year. Total revenue in the second quarter of 2025 was comprised of net product sales of $158 million and royalty, licensing, and other revenues of $7 million. Excluding net product sales of Trokendi XR and Oxtellar XR, total revenues for the second quarter of 2025 increased 17% compared to the same quarter last year. This increase was primarily due to an increase in net sales of our core products: Qelbree, GOCOVRI, and ONAPGO. For the second quarter of 2025, combined R&D and SG&A expenses were $116 million as compared to $112 million for the same quarter last year. Operating earnings on a GAAP basis for the second quarter of 2025 were $12 million as compared to $23 million for the same quarter last year. The decrease was primarily due to higher sales and marketing expenses related to the ONAPGO launch. GAAP net earnings were $22 million for the second quarter of 2025, or $0.40 per diluted share, compared to GAAP net earnings of $20 million, or $0.36 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 2025 were $41 million, compared to $45 million in the same quarter of the prior year. Total revenues for the six months ended June 30th, 2025, were $315 million, compared to $312 million in the same period last year. Total revenues were comprised of net product sales of $300 million and royalty, licensing, and other revenues of $15 million. Net product sales were flat compared to last year. The increase in net product sales of our core products, Qelbree and GOCOVRI, was generally offset by decreases in product sales of APOKYN and the generic erosion of Trokendi XR and Oxtellar XR. Excluding net product sales of Trokendi XR and Oxtellar XR, total revenues for the six months ending June 30, 2025, increased 21% compared to the same period last year. Again, the increase was primarily due to the increase in net product sales of our core products, Qelbree, GOCOVRI, and now ONAPGO. Combined R&D and SG&A expenses for the six months ended June 30th, 2025, were $233 million as compared to $224 million for the same period last year. Operating earnings on a GAAP basis for the six months ended June 30th, 2025, were $2 million as compared to $19 million for the same period last year. The decrease in operating earnings was primarily due to a change in the fair value of contingent consideration and higher selling and marketing expenses associated with the ONAPGO launch. GAAP net earnings were $11 million for the six months ended June 30th, 2025, or $0.19 per diluted share, compared to $20 million or $0.36 per diluted share in the same period last year. On a non-GAAP basis, which excludes amortization and intangibles, share-based compensation, contingent consideration, and depreciation, adjusted operating earnings were $67 million compared to $68 million the same period last year. As of June 30, 2025, the company had approximately $523 million in cash, cash equivalents, and marketable securities, compared to $454 million as of December 31st, 2024. The increase is primarily due to cash generated from operations. We used a portion of our current cash on hand to fund the acquisition of Sage, which was completed on July 31st. Following the acquisition, the company continues to have a strong balance sheet with no debt and significant financial flexibility for potential M&A or other growth opportunities. Now turning to guidance, we are updating our full year 2025 financial guidance primarily to reflect Supernus strong performance in the first half of the year and the impact of the Sage acquisition starting August 1st. We expect total revenues to range from $670 million - $700 million, up from the previous range of $600 million - $630 million, comprised of net product sales and royalty and licensing revenues. Note that total revenue guidance for the full year 2025 assumes approximately $65 million - $70 million of combined net sales of Trokendi XR and Oxtellar XR, which remains unchanged. For the full year 2025, we expect combined R&D and SG&A expenses to range from $505 million - $530 million, up from the previous range of $435 million - $460 million. The increase is primarily due to the inclusion of Sage OpEx for the final five months of 2025. Overall, we expect full year 2025 operating loss in the range of $70 million - $80 million, compared to the previous range of $10 million operating earnings to an operating loss of $15 million. This change is due to the inclusion of two items: $55 million - $60 million in Sage acquisition-related costs and an estimate of $10 million - $20 million in increased non-cash amortization related to the Sage acquisition for the final five months of 2025. Finally, we expect our non-GAAP operating earnings to range from $105 million - $135 million, which is relatively consistent from the previous guidance. Please refer to the earnings press release issued prior to this call that identifies the various ranges of reconciling items between GAAP and non-GAAP. With that, I will now turn the call back over to the operator for Q&A. Thank you. At this time, we will conduct a question and answer session. As a reminder, to ask a question, you will need to press star 11 on your telephone and wait for your name to be announced. To withdraw your question, just press star 11 again. Please stand by while we compile the Q&A roster. One moment, please. Our first question comes from Stacy Ku of TD Cowen. The floor is yours. Hey, thanks so much for taking our questions and congratulations on a great quarter. First question is on Qelbree. Can you just talk about what kind of net pricing dynamics we saw in the quarter and maybe how we should think about the quarterly, let's say, net pricing for Qelbree moving forward? In addition, maybe provide an update on the Qelbree launch progress in the adult segment and maybe that understandable focus on the back-to-school season for Q3? That's the first question. The second question is on ONAPGO. Just help us understand the 750 enrollment forms and 300 prescribers of ONAPGO and what we're seeing in Q2 in terms of sales. Just help us understand reimbursement timelines to getting coverage patients on maybe paid drug or just help us understand that clear demand that we're seeing as it relates for ONAPGO versus maybe even AbbVie's ViLev when we look at the sales they've reported and the type of demand they're seeing? That's our second question. Thanks so much. Yeah, starting with Qelbree, if you look at the net pricing, it continues to be north of the $300 per prescription for a 30-day prescription. The gross to net, as we made a previous commentary in previous quarters, we expected it to improve, obviously, versus the first quarter, and it did. Actually, it was pretty much around the same level it was in the second quarter of last year, so we're staying consistent with that. Regarding your question on the adult segment, as I mentioned in my prepared remarks, the adult business, which we've been investing in clearly because of the size of that segment and its importance for the health of the brand and its continued growth, it is starting to show some traction. Now the business is about 35% of the total prescriptions of Qelbree. Adult prescriptions grew by 29% compared to about 20% for pediatrics. Pediatrics grew very well, of course, by 20%, but the adult performed a little bit more with 29% growth. Having said that, of course, it's also a lower base, so percentage-wise, it's going to show that anyway. We're very pleased with the continued growth on the adult. We're very happy that Qelbree actually performed pretty well during the summertime. We think some of that is also because of the increased growth in the adult side because the adult patient population does not get impacted as much with the seasonality that we see on the pediatric side. Given the high growth on the adult business, it helped us go through summer fairly. The business, we look at the prescriptions of Qelbree, they held up really nicely during the summer months versus typically they could potentially decline. We're very happy with the fact that we're now in the back-to-school season with a very good momentum behind the brand and a much stronger position than we've ever been to continue to push through. We're looking for hopefully even a much stronger second half for the brand. On ONAPGO, the 750 enrollment forms, these are the forms that are submitted by our prescribers. The deadline for these forms to eventually get adjudicated, everything gets processed for them to translate into actual shipments. That's where, in the end, you'll see some. The key thing is it's like a funnel. You've got to keep filling in the forms because eventually you're going to lose some of them. That's typical in the industry. In all specialty products, you lose a good portion of these forms, and they don't all translate into actual patients. Right now, and this number is probably around the end of July, so it's not in this end of second quarter, but by the end of July, we estimate we have about slightly more than 200 patients on ONAPGO. We're very excited about that. We have a very good number of patients who are getting the product. A good portion also, a little bit north of 20%, 25%, are already getting refills, starting to get refills. The momentum is really starting to build up behind the product, given that we just launched it a couple of months ago, late in April. We're very happy about that and also very happy about the fact that we have more than 300 prescribers. We estimate about 50% of the prescribers are actually repeat prescribers. Everything is really pointing in the right direction for the very long launch on ONAPGO. Wonderful. Just to confirm, those 200 patients that you're saying, slightly more than 200 that are on ONAPGO, you guys are getting reimbursement for that, or is there more of a, let's say, specialty pharmacy bridging program that's ongoing? No, I mean, from a reimbursement coverage point of view, that is going as smooth as you can expect for a launch. We are going to always have bumps on the way, but we're pretty happy with the amount of prescriptions that are going through, getting authorized. We are working the system as time goes on. We work any kinks in it, but we're very happy with that and the amount of patients that are getting the shipments for the product. Okay. Understood. Thank you for your question. Our next question comes from Andrew Sy from Jefferies. The floor is yours. Hey, congrats on the quarter. This is John on for Andrew. Thanks for taking my question. We saw ZURZUVAE Q2 sales accelerate meaningfully quarter over quarter. Were there any one-time events driving that sales growth, or was it all mostly organic? Do you expect that pace of growth to continue going forward into Q3 and Q4? Maybe just broadly speaking, what do you think about the peak sales opportunity? Ultimately, what could be your appetite in looking at ZURZUVAE and like MDD or any other CNS indications in the future? Should we really be thinking that we focus on the launch and kind of keep the pipeline shell for now? Thanks. Yeah, the only thing I can really speak about ZURZUVAE, given that we just closed on the transaction, we'll be coordinating, of course, messages and what we do from a public disclosure perspective with our partner, Biogen. I can give you a little bit more color, given you know what Sage has reported. Based on what Sage has reported, in the second quarter, they show 36% growth in the prescriptions. About 44,000 TRXs were shipped to women with PPD. That is a very strong, healthy growth. If you recall, in the first quarter, actually, they grew by 22% versus the fourth quarter of last year. We're really excited about the momentum that the brand is picking up. Clearly, that is also a benefit of some of the expansion that the two partners have done, Biogen and Sage, at that time with the expansion of the salesforce and the continued investment behind the brand. We're pretty pleased with the strong growth in the business on a yearly basis. Obviously, that is being reflected, of course, in the dollar. On the dollar side, again, as I said, we just closed on the deal, so we need a couple of days to a little bit understand if there is any shift in inventory or anything else that may have benefited the dollar amount. I don't have a clear answer for you at this point. Clearly, what's more important is the shipments and the prescriptions, and that's what we're very focused on at this point. As far as peak sales of the brand itself, again, we haven't made any specific public commentary. The only thing I can tell you, which is public information, of course, everybody knows the milestones we have with the purchase of Sage. We will be very happy to pay all these milestones and the CDRs that we have on the deal. That gives you some idea for what the brand, you know, or the level of sales that we're thinking, and we will be working very hard to achieve, you know, for this product. I'll just remind folks that these milestones or the sales numbers are actually 50% of what the total brand would be because that would be the net revenues as reported by Supernus for these CDRs. Finally, regarding any potential future indications or anything specific with that, again, I'm not at any specific liberty at this point to talk about the future plans of the product until we sit down, you know, and talk to our partner, Biogen, regarding the potential of the brand. Certainly, we're in it for the long haul, and we're in it to build as big of a product as possible here to serve as many patients. Great. Thank you so much. Thank you for your question. Our next question comes from Kristen Kluska from Cantor Fitzgerald. The floor is yours. Hi, everyone. Congrats on a great quarter. Two questions for me. The first is just on Qelbree. Obviously, in 2Q, you introduced a lot of new sales launch initiatives. I'm curious, with all the new prescribers that are coming on board, what are some of the key reasons doctors are wanting to try this option? How much of the recent launch has been dictated by doctors offering this to patients versus patients asking their doctors about it? Yeah, so it's really a combination of all that, Kristen. There is no one specific initiative that is really driving the strong performance of the brand. Clearly, at the beginning of the year, what I believe you're referring to is the new label that we got or changes in the labels that were very, very favorable for the product from the perspective of first really clarifying and providing more information about the mechanism of action of Qelbree, which separates the product significantly versus a lot of these options that are out there, specifically with its activity and modulation of the serotonin. That really differentiates the product and explains also a lot of its activity and how it treats ADHD and the way patients feel when they get the product. A lot of the time we spend in the first quarter, of course, also in the second quarter, educating physicians about the change in the label, the mechanism of action. We spend a lot of time in pushing the adult business, as I mentioned earlier. We're doing a lot of things on different fronts, and a lot of these things tie together. The change also in the addition of the lactation data, you know, that is also important for patients, female patients who are in the adulthood and so forth. A lot of things tie together. All these initiatives have converged and really produced the results that we've seen behind the brand. Now with the back-to-school season, clearly, we will shift some of the emphasis back on the pediatric side to take the most advantage of the momentum of the back-to-school season. That would be great for us in the third quarter to continue with the push for the product to hopefully, as I mentioned earlier, that we finish even stronger in the second half, even stronger than the first half. Thank you so much for that. With the Sage deal closed now, can you give us a rough sense of what that pro forma cash looks like? I know they did have a good amount of cash left on their balance sheet. Just on the sense of the future M&A or in-licensing opportunities, should we expect there to be more focus specifically in the OB/GYN space as you build the salesforce and do the work there for PPD? Thanks again. Yeah, sure, I'll take this to the other part of the question and allow the asking to talk specifically about the cash. From a corporate development perspective, strategy perspective, our top priorities are pretty much still the same. First, starting with revenue-generating products that could continue to build our commercial footprint in CNS. Now, as you mentioned, given that now we're getting into the OB/GYN space, definitely women's health will be an area that we will be looking at very seriously. It opens up a whole area for us, an additional growth opportunity for us. We will be looking at both areas, as always, CNS, neurology, psychiatry, but also now with OB/GYN. As far as the size of the transaction, all depends on the case-by-case scenario, the type of products we're bringing in. Also, regarding the balance sheet, I'll let Tim now comment concerning your question about the cash, the pro forma cash position. As I mentioned in my prior remarks, we still have a strong balance sheet. At the time of close, our cash is between $240 million and $260 million. That should clearly give us continued flexibility, given that we still have a very strong and healthy balance sheet overall. Thank you so much. Thank you for your question. Our next question comes from Annabelle Samimy from Stifel. The floor is yours. Hi, this is Jack on for Annabelle. Thanks for taking our questions. On the topic of the OB/GYNs, you've noted that this is the best area for expansion for ZURZUVAE. Your real point of leverage historically has been psychiatry. How do you plan on balancing these two? What type of investment do you need to make to kind of reach these prescribers? Does Biogen need to kind of get on board with that decision? Yeah, I mean, at this point, currently, so far, what we've seen is that 70% - 80% of the prescriptions are generated by OB/GYNs. Clearly, the business is heavily skewed, which makes a lot of sense, of course, given the patient journey, where it starts and where it ends and so forth. The remainder of the prescription, 20% or so, is in the psychiatry space. That's not too small. Clearly, that is an area where we will be exploring. Again, we will explore that together with our partner, Biogen, to see how we can, if there is a chance here, to potentially take advantage of our strong presence in psychiatry. Does it make sense? Can we expand further in the psychiatry space? You bet, I mean, that is something we will be talking about with our partner. Any decisions will have to be made, of course, jointly as to what kind of expansion, if there is any expansion, investment, or whatever it is, where we can explore that avenue and further improve and increase the reach so we can reach patients who go to the psychiatry office. That is clearly an area we will be exploring as we move forward. Thanks. One more from us. Just wanted to understand the dosing dynamics for Qelbree in adults a little bit better. Is there still the same level of combination usage with stimulants? If so, why is that so persistent? I would think that would kind of defeat the purpose and advantage of Qelbree being a non-stimulant in that case? Yeah, it's actually driven by the stimulants themselves and how nasty they can be, of course. Otherwise, why would a physician be considering to switch or add Qelbree or switch to Qelbree, right? That means there is a problem. There is something that the patient is struggling with, and the stimulant on its own is not really doing what it's supposed to do, meaning, you know, address the symptoms that the patient is going through. Instead of completely taking the patient off the stimulant, which has a lot of issues with it when you do that—withdrawals, a lot of patients feel withdrawal and suffer from all kinds of symptoms when you cut them off completely from the amphetamines or methylphenidates—what physicians try to do is taper off the dose of the stimulant over time and then, as time goes on, increase the dose of Qelbree. Therefore, the use of Qelbree in combination with the stimulants perhaps would continue to be the case. Physicians like to do that because they don't want to take patients off completely, very quickly, very suddenly off the stimulants. They like to titrate up on Qelbree and add it. Therefore, the reason why we see a very good, healthy level of use as a combination. It continues to be around the 40% of adult prescriptions to be combination use. In pediatric, it's less so. It's about 20% we estimate of the pediatric prescriptions are combination. That dynamic continues to be the case. Eventually, what happens with the patient is they're off the stimulant. Actually, a lot of them, interestingly, they find out that they don't have to have any more two prescriptions or two stimulants that they used to take because a lot of them used to take the controlled release, let's say, amphetamine, and then later in the day, they need to supplement with an immediate release because even the extended release doesn't cover and give them the full coverage for the full day. With Qelbree, what they're finding out is that with one pill, that's all what they have to do is take Qelbree once a day, and it truly gives them full 24-hour coverage. Qelbree has a lot of advantages clearly by giving them the full day coverage without having to take two different products. Of course, a very different profile continues to have good efficacy, and that's why people continue to use it. Actually, in adults, the satisfaction is pretty high among physicians who have tried Qelbree and continue to add more patients in their offices, adding more patients on Qelbree. Very helpful. Thanks for the explanation. Thank you for your question. Our last question comes from David Ams ellem from Piper Sandler. The floor is yours. Hi, thanks for taking our question. This is Alex on for David. Can you please talk to your commercial infrastructure to support ZURZUVAE in postpartum depression, particularly in terms of headcount and how many practitioners it's targeting and anything you plan to do differently than Sage? Thank you. At this point, unfortunately, I'm not at liberty to get into the details of the infrastructure, the salesforce, the number of, and so forth, until we have some time to discuss with our partner, Biogen. We will reserve that till later. We're happy to provide any color later if that is something that our partner would like to talk about publicly. For now, we can't make, unfortunately, any comments on that. Okay, thank you. Thank you for your question. This concludes the question and answer session. I would now like to turn it back to Jack Khattar for closing remarks. Thank you for joining us to learn about our second quarter 2025 operating performance and highlights. The company continues to execute well, setting the stage to make 2025 the year when we complete the transition from our legacy products to Trokendi XR and Oxtellar XR. With the addition of ZURZUVAE, the launch of ONAPGO, and the continued robust growth of Qelbree and GOCOVRI, we have just entered a new phase in our history, a phase of renewed and accelerated growth and profitability. Our strengthened portfolio of four core growth drivers will position us to further accelerate the growth in revenues and earnings. We are also focused on generating strong cash flows behind the strength of our expanded product portfolio and through the efficiency of our operations. 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 the program. You may now disconnect.
