Thank you, David. Good afternoon, everyone, and thank you for joining us today. We had an exceptional second quarter with record revenue, significant margin expansion and important progress across both our commercial portfolio and pipeline. We also completed several strategic transactions that we believe will support Eton's continued long-term growth. I'll begin by highlighting a few of the quarter's key accomplishments. We once again achieved record revenue, delivering 99% year-over-year growth with contributions from across the portfolio. At the same time, we delivered significant margin expansion and accelerated adjusted EBITDA and net income growth. We established a strong commercial foundation in pediatric dermatology with the successful relaunch of HEMANGEOL, which is already performing ahead of our expectations. We expanded our portfolio through the acquisition of U.S. rights to IMPAVIDO and the licensing of ASN-001, adding both a commercial rare disease product and a late-stage development candidate that we believe has the potential to become the largest product in our portfolio. And finally, we had a very productive few months on the R&D front. We submitted a PAS, prior approval supplement, for the KHINDIVI label expansion, initiated the ET-700 pilot study, began preparations for the INCRELEX label harmonization study and also received Fast Track designation for AMGLIDIA. Starting with the financials, it was another record quarter for Eton. Revenue reached $37.6 million, an increase of 99% year-over-year. HEMANGEOL had an exceptional relaunch quarter and was the largest contributor to our growth. But importantly, the strength was broad-based with continued momentum across our pediatric endocrinology franchise and GALZIN. Based on our strong second quarter performance and favorable outlook for the remainder of the year, we are once again raising our 2026 revenue guidance. We now expect full year revenue to exceed $145 million, up from our previous guidance of more than $120 million. Profitability has always been a core focus at Eton, and that was apparent in our results this quarter. Adjusted EBITDA increased to $16.2 million or 43% of revenue compared with $3.6 million or 16% of revenue in the prior year quarter. Even after new incremental expenses related to the ASN-001 transaction, which I will discuss in detail shortly, we now expect our full year adjusted EBITDA margin to exceed 35%, up from our prior guidance of greater than 30%. For the last several years, we've talked about the scalability and operating leverage inherent in our model. We're now seeing that play out in the financial results. As we continue to grow revenue, we expect an increasing proportion of that growth to translate into earnings. Longer term, we continue to believe this business can generate an adjusted EBITDA margin above 50%. Turning to our product portfolio, I'll start with the dermatology, pediatric dermatology, which has quickly become an important new franchise for Eton. We relaunched HEMANGEOL as planned on May 1, and the product is performing ahead of our expectations. Historically, approximately 8,000 patients annually were treated with HEMANGEOL, and the patients accessed the product through 18 different pharmacies. When we acquired HEMANGEOL, we saw a significant opportunity to streamline and improve that experience by moving patients to a single high-touch access model through Eton Cares, reducing patient out-of-pocket costs, accelerating access to medication and providing 24/7 patient support. Transitioning an entire patient population to a new distribution model was a significant operational undertaking, particularly given the nature of infantile hemangioma treatment, where therapy typically lasts only about 6 months. We weren't simply transitioning a static patient population. We were simultaneously converting existing patients, onboarding newly diagnosed infants and supporting patients completing therapy, all while introducing physicians and their office staff to an entirely new access and fulfillment model. We originally expected that transition to take 3 to 4 months. I'm very proud of our team's execution. By the end of June, we estimate that approximately 95% of patients had transitioned to the new model, well ahead of our expectations. Critically, this was accomplished while maintaining continuity of care for patients and their families. Today, every hemangioma patient has access to the full Eton Cares patient support program. Previously, many families were paying approximately $55 per bottle, which, in some cases, could total more than $100 per month. Our goal is simple. Families dealing with infantile hemangioma shouldn't also have to worry about whether they can afford the medication their child needs. With the transition of existing patients largely behind us, our commercial attention is now shifting to the broader opportunity, helping ensure that more infants for whom HEMANGEOL is appropriate receive a therapy specifically developed and approved for infantile hemangioma instead of relying on off-label adult formulations. Those off-label products were not developed for infantile hemangioma and contain excipients such as alcohol, sugar and other ingredients that are not appropriate for infants. In our conversations with physicians, we've consistently heard that the historical out-of-pocket cost of HEMANGEOL was one factor contributing to off-label prescribing. With Eton Cares and our $0 co-pay program now in place, we believe we've removed an important barrier to broader adoption and are well positioned to drive continued growth. We are extremely pleased with the HEMANGEOL acquisition. It has quickly become our largest product and established Eton as a leader in the infantile hemangioma space. But as we've spent more time with pediatric dermatologists, vascular anomaly specialists and families, it's become clear that HEMANGEOL addresses only part of the treatment landscape. For severe hemangiomas requiring treatment, HEMANGEOL is the established standard of care, and we estimate that population to be approximately 10,000 to 15,000 patients annually. But infantile hemangioma affects more than 100,000 patients annually in the United States and exists across a broad spectrum of severity. This means that a significant number of infants with moderate infantile hemangiomas, we estimate 10,000 annually, are being treated off-label with ophthalmic timolol because there simply isn't an FDA-approved topical therapy available. These timolol ophthalmic products were developed for glaucoma, not infantile hemangiomas, and present a number of practical limitations, including variable dosing, formulation challenges, the absence of FDA-approved labeling and reimbursement limitations. To us, that represented both a clear unmet need, and we saw firsthand the evidence that physicians and families are looking for a better option. That is what ultimately led us to ASN-001, which was specifically developed for infantile hemangiomas and is supported by clinical data. There are several reasons we're particularly excited about ASN-001. First, the potential patient population could be 2 to 3x larger than HEMANGEOL. Second, ASN-001 is expected to be prescribed by the same health care professionals as HEMANGEOL, allowing us to leverage our existing commercial infrastructure and the strong relationships we have already been building with thought leaders in vascular anomaly centers. And third, as a new product launch, ASN-001 would not be subject to certain rebate dynamics that weigh on HEMANGEOL's gross to net. As a result, we believe ASN-001 will likely have more favorable net pricing economics for Eton. Put those factors together, and we believe ASN-001 has a clear path to becoming the target -- the largest product in our portfolio. And to be clear, we expect ASN-001 to complement HEMANGEOL rather than compete with it. The 2 products address different segments of the disease spectrum and together would allow Eton to support physicians treating infantile hemangiomas across a much broader range of patients. With ASN-001 in our portfolio, we believe the addressable market could expand to approximately 20,000 to 30,000 patients annually. From a development standpoint, ASN-001 has already completed a Phase III trial that showed compelling efficacy compared with placebo. Our final remaining development requirement is a bioavailability bridging study, which we plan to initiate in the coming weeks. The proposed study protocol has been reviewed by the FDA and consists of a 24-patient, 29-day study assessing the pharmacokinetics of ASN-001, and we expect that study to cost approximately $4 million over the next 12 months. Following completion of the study, we expect to be ready to submit the NDA in the second half of 2027, allowing for a potential approval and launch in 2028. We believe the ASN-001 transaction, together with the HEMANGEOL acquisition earlier this year, demonstrates 2 defining aspects of Eton's strategy and capabilities. First is our ability to identify and execute highly strategic, potentially transformational transactions. At the end of 2024, INCRELEX represented a transformational acquisition and became our largest product. Now in just the last 6 months, we have acquired and successfully integrated what has become our largest revenue-generating product while also adding what we believe is now our highest value pipeline program. And we accomplished both without external financing and while expanding profitability. We believe that combination demonstrates the strength of our business model and our disciplined approach to capital allocation. We will continue pursuing commercial and development-stage transactions that we believe can accelerate revenue and earnings growth and create significant long-term value for our shareholders. The second defining capability is what we believe to be one of Eton's greatest competitive advantages, our ability to thoughtfully enter new therapeutic areas and rapidly build leadership positions by leveraging the commercial capabilities we've already established. Pediatric dermatology is a great example. We entered the market with HEMANGEOL on May 1. Just 90 days later, we expanded that franchise with ASN-001, a product that can leverage the same commercial organization, customer relationships and foundational infrastructure. We've successfully executed this playbook before. We entered pediatric endocrinology with ALKINDI SPRINKLE and then expanded that platform with 3 additional high-value commercial products in the specialty. Similarly, we entered metabolics with carglumic acid and subsequently expanded the platform through additional transactions. Importantly, we've been able to build these franchises while continuing to grow our existing portfolio and maintaining discipline around operating expenses. We've proven this is a repeatable strategy and one that Eton is particularly well positioned to execute. We expect to enter a number of new specialties in the coming years. Ultimately, our mission is simple, bringing as many important rare disease therapies to patients as possible. Beyond infantile hemangioma, we've had a number of important developments across our commercial and development-stage products. We won't have time to cover all of them this afternoon, but I'll highlight several of the most significant. And I'll start with our high-performing pediatric endocrinology portfolio. Our adrenal franchise of ALKINDI SPRINKLE and KHINDIVI continues to deliver the reliable, steady growth we've seen for more than 5 years. We have now exceeded 600 active patients and continue to grow. Last week, we announced that our new KHINDIVI formulation successfully demonstrated bioequivalence to the reference product, ALKINDI SPRINKLE. As a result, we were able to submit our prior approval supplement requesting approval of a broader age range. KHINDIVI is currently approved for patients 5 years of age and older. We continue to believe expanding the label to include patients under 5 would be an important catalyst for broader adoption and accelerate our path toward our goal of 1,000 active patients. We expect the expanded label to be approved in the first half of 2027. We also launched DESMODA at the end of the first quarter and have been very encouraged by the early response from the endocrinology community, who are glad to have the option of an oral liquid desmopressin solution to enable individualized dosing. Desmopressin dosing can vary significantly from patient to patient and often requires multiple dose adjustments throughout the treatment journey. DESMODA was specifically designed to address that need through precise, flexible dosing, and that differentiation is resonating strongly with clinicians. Beyond the launch itself, DESMODA is also helping us establish relationships with adult endocrinologists, expanding our commercial reach beyond our traditional pediatric call point. We are continuing to invest in peer-to-peer education, engage key opinion leaders and build awareness through national and regional medical meetings, which include a strong presence at the Endocrine Society Annual Meeting in June. These activities are supporting the DESMODA launch while also strengthening our broader endocrinology platform and creating opportunities across ALKINDI SPRINKLE, KHINDIVI and INCRELEX. INCRELEX also delivered strong year-over-year revenue growth during the quarter, and we continue to advance our label harmonization study, which we believe could substantially expand the product's long-term market opportunity. The FDA has signed off on our study protocol, and we have executed an agreement with a leading CRO to initiate the study. Our team is now actively engaged in study start-up activities with the goal of dosing the first patient by the end of the year. Rounding out our pediatric endocrinology portfolio is AMGLIDIA. We recently received Fast Track designation from the FDA, which is designated or designed to facilitate the development and expedite the review of drugs intended to treat serious conditions and fill an unmet medical need. AMGLIDIA is a liquid glyburide product used to treat neonatal diabetes, an extremely rare condition affecting only a few hundred children in the United States. While the product is approved and widely used in Europe, there is currently no approved oral treatment for neonatal diabetes in the United States. We are initiating the product's bioavailability study this month and plan to submit the NDA by the end of the year, allowing for a potential approval and launch in 2027. Given the Fast Track designation, we intend to request priority review with our NDA submission. Now, moving on to our Wilson disease franchise. GALZIN once again delivered strong revenue growth during the quarter as we continue to convert patients who have historically relied on over-the-counter zinc products. Despite the progress we've made since the relaunch, we believe we have converted less than half of the patients currently managed with zinc therapy. That leaves a substantial opportunity for continued growth. We're continuing to strengthen the franchise through our strategic partnership with the Wilson Disease Association, deeper engagement with leading centers of excellence and expanded participation at hepatology congresses. Combined with the differentiated support offered through Eton Cares, we believe these investments position GALZIN well ahead for sustained growth. Longer term, we see an opportunity to further expand our Wilson disease franchise with ET-700, our proprietary, patent-pending, extended-release formulation of zinc acetate. Our pilot study is currently ongoing. It is a double-blind, placebo-controlled clinical trial involving 36 healthy volunteers. The study will use PET scans with radioactive tracer copper to compare the effects of GALZIN, ET-700 and placebo on intestinal copper absorption. We expect initial results in the next month or 2 with the full study report expected by the end of the year. If successful, the pilot study would support the initiation of a pivotal clinical study in early 2027. If ultimately approved, we believe ET-700 could potentially exceed $100 million in peak annual U.S. sales. Lastly, I'll finish the portfolio discussion with another recent addition, IMPAVIDO. IMPAVIDO is the only FDA-approved oral therapy for severe forms of leishmaniasis, a rare but potentially life-threatening parasitic disease that could cause severe skin lesions, disfiguring mucosal disease or life-threatening visceral infection. As a life-saving treatment for an ultra-rare condition, IMPAVIDO was a strong strategic fit for Eton, and we believe patients will benefit from expanded access through our Eton Cares program. Eton will also begin distributing the product in the U.S. in late September, and we expect IMPAVIDO to be another strong addition to our growing portfolio of orphan therapies. At the beginning of this year, we laid out 3 ambitious long-term goals for Eton. First, to exit 2027 at a $200 million annualized revenue run rate. We now believe that Eton is well ahead of this goal. Second, to achieve a 50% adjusted EBITDA margin in 2028. As noted, we have already exceeded 40% in the second quarter this year, and third, to reach $500 million in annual revenue by 2030. Clearly, with the addition of ASN-001, Eton expects to achieve or exceed this goal. Following our first half performance, the successful HEMANGEOL relaunch, the addition of ASN-001 and the continued strength of our broader portfolio, we believe we are well positioned to sustain momentum into the future. Just as importantly, our recent success has put Eton in an even stronger position to continue pursuing value-creating business development opportunities. Our commercial track record has demonstrated to potential partners that Eton can be an excellent partner for commercializing ultra-rare disease products in the United States. And our growing profitability has expanded our financial capacity, allowing us to pursue a broader range of transactions, including potentially larger opportunities. We remain incredibly excited about Eton's future. We believe we are still in the early stages of building a leading rare disease company in the United States, and our mission remains unchanged, to bring as many important therapies as possible to patients with rare diseases while creating significant long-term value for our shareholders. With that, I'll turn it over to Judy Matthews, our Chief Financial Officer, to discuss our financial results. Judy?
