Thanks, David. Thank you all for joining us this morning. For those of you who don't know me, I've been a member of the WeightWatchers Board since mid-2023, and I'm now serving as Interim President and CEO following Sima Sistani’s departure last month. I'm confident I speak for the entire board when I say how grateful we are to Sima for her leadership navigating the business through these times of significant change in our industry, while also laying a strong foundation for our future. I'm extremely pleased to now be part of this management team as we take on the task of building on that foundation and creating the plan to revert this business back to sustainable growth. While our results in the third quarter were broadly on track with expectations, it's clear we have significant work ahead to change the trajectory of the business. This is an industry undergoing massive transition and as a result Weight Watchers has experienced meaningful disruption over recent years. However, I am optimistic about our ability to lay a path to future growth. From the value of our full and expanding spectrum of solutions to the strength of our brands and our important role in the evolving global healthcare landscape, we have the fundamentals of what we need to be successful. We know that the future of weight management is one where clinical options are paired with behavioral solutions, not either or, and that WeightWatchers is uniquely positioned to provide this to consumers at scale. This is a defining time for our field and our company. We need to ruthlessly assess and fix parts of our business not currently performing to the levels required. The team is committed to moving fast to make change, yet we know the scale of the task at hand will take time. However, let's remind ourselves that WeightWatchers have successfully navigated disruption and transformation many times in our 61 years, emerging each time with greater strength and clarity of purpose. We are confident in the importance and relevance of our mission to empower people to live healthier, longer lives through our trusted leadership position and our many advantages that give us the right to win. As we look ahead to the future of this business, I see many areas of unquestionable strength. Firstly and perhaps most importantly, we have a portfolio advantage. While many newer entrants to our base focus on just one part of our solution set, we have built with intentional breadth, not only depth. Our full spectrum weight management platform is uniquely positioned to meet members' needs wherever they are on their weight journey. Under the leadership of Chief Product Officer, Donna Boyer, who's with us on the call today, we're actively focused on making it much easier for our members to more fluidly move in and out of and across the various components of our program. We believe in building solutions for a healthy life tailored to a member's individual needs, not isolated products for specific moments in time. This is perhaps our biggest opportunity and the area in which we have the most immediate and sizable work to do. Secondly, we have a scientific advantage. We've spent decades investing in research and development to bring our members programs that work. With over 175 published papers of clinical research and more underway specific to our GLP-1 program, we time and time again prove the efficacy of our solutions. As for one example, we know our behavioral program is 3.5x more effective for our members than trying to lose weight only with standard nutritional guidance. We also know that our WeightWatchers clinic members taking weight loss medication paired with our nutritional points program lose 11% more than those using medications alone and that 81% of WeightWatchers clinic members agree that compared to primary care, we provide better ongoing care and support. There are so many more proof points and they matter more and more in a world of increasing volumes of false claims and misinformation. Thirdly, our community is a distinct advantage and a highly motivated one. We've seen 60 million plus members over our history supported by thousands of our incredibly dedicated coaches, clinicians, care team and field staff. Each member has access to a dynamic online community through our app which sees high levels of engagement as well as in-person and virtual communities through our workshops. Roughly 20% of our members at any time are on our program with a friend and those referred by a friend have both a 20% higher retention rate and lose approximately 45% more weight by week 12 compared to other members on the program. Talk about the benefit of community. In addition, we have a vast community of prior members, a significant portion of whom return to WeightWatchers at various stages of their weight management journeys and who represent a meaningful opportunity. This is particularly evident in WeightWatchers clinic where over 60% of signups year to date have come from existing and prior WeightWatchers members. Our entire business was formed on the basis of people coming together to help and support one another and we continue to have a workshop business that while evolving for a digital world remains an important part of our competitive offering. Don't ever underestimate the power of an engaged community. And finally, our clear advantage with our iconic trusted brand. We have 60 plus years of expertise in legacy and time and time again, our consumer research has shown that we remain a brand that people trust with proven programs. We started some initial work to refresh our brand under the leadership of our recently appointed Chief Brand Officer, Phillip Picardi, to bring renewed energy to how we engage with both existing members and potential future customers. I'm excited for the first glimpse of this work during the third quarter and our peak season. While the visual updates will include a fresh direction and move us forward, our messaging will reflect the values that have always set us apart: community, joy and livability. WeightWatchers continues to have roughly twice the brand consideration of our nearest competitor. So we have a strong starting point from which we're excited to build upon and grow. As well as refreshing our brand, we'll be doubling down on our end-to-end marketing strategy. Too often our marketing feels confused and lacking a clear call to action or a reason to engage. As we've expanded our solutions to include clinical and adapted to a rapidly evolving market, we need to refocus on clearly communicating the full value and breadth of our comprehensive offerings. A common theme in our focus for the coming quarters is the need to untangle complexity across different areas of our business, simplifying our approach to drive improved results. Stepping back, we're confident we have the assets needed to thrive in today's high growth weight management space. However, there's urgent and significant work ahead to bring it all together into a cohesive solution to more effectively communicate the value and impact and to meaningfully improve the experience once you're in the WeightWatchers ecosystem. We're fully committed to realizing this potential and look forward to sharing our progress along the way. Moving on to our portfolio of solutions, there's been a lot of focus on our clinical business since our acquisition of Sequence. This is an area of the market in significant demand with some predicting that up to 30 million people in the U.S. may be using GLP-1s by 2030. As expected in early growth cycles, this surge in demand has also drawn new competitors, increasing customer acquisition costs and flooding key channels with content and information. The rapid adoption has also outpaced supply resulting in drug shortages and prompting the introduction of compounding solutions to meet demand. To address continued drug shortages, expanding both accessibility and affordability of our clinical weight management solution, we recently added compounded semaglutide to our wide formulary of branded and other generic medications. Lack of access and affordability are the primary reasons for the churn of the clinic subscriber. The combination of a slowly improving supply trend, albeit still low, with a number of improvements in our member journey helped us improve clinic member retention to 7.5 months in the third quarter from 6.5 months in the second. In addition to shortages, insurance coverage remains a prohibitive factor for most. Over the last six months, approximately 45% of WeightWatchers clinic members eligible for and prescribed a GLP-1 by their clinician have been denied coverage by their insurance after three prior authorization requests. In fact, over 50% of current WeightWatchers members have expressed consideration of a compounded GLP-1 largely due to these factors. And that's why after thorough research and careful evaluation, we partnered with a trusted FDA registered 503B outsourcing facility that meets our high standards for quality and patient care. We saw an immediate and positive impact on sign ups in our clinical business following this launch with the single highest day for clinic sign ups in 2024. Performance has continued to be positive to date with signups remaining elevated to prior months, albeit we do not expect compounding to have a material impact on our 2024 overall business results due to the relatively small number of new clinical subscribers in proportion to our overall business. However, we're pleased to see the positive trend continue into the fourth quarter with our clinic subscribers today representing growth from the end of Q3. We're committed to ensuring our members have access to the solutions they need while maintaining full regulatory compliance. We're optimistic that supply issues can be resolved allowing branded medications to reach even more people who need them and WeightWatchers is best positioned to meet that additional demand. Although competition continues to drive a significantly higher cost of acquisition compared to the same time last year, which caused us to be cautious with marketing spend in the third quarter and ongoing medication shortages have impacted this area of our business throughout the year, we're confident in the meaningful growth opportunity the clinical offering represents for our business over the long-term. While we're expanding our clinical offering, our research shows that only about 10% of GLP-1 users intend to remain on these medications for the rest of their lives. This is where the comprehensive WeightWatchers behavioral program, specifically the program we tailored for those on GLP-1s, can serve both as an effective foundation while on medication, ensuring critical complementary nutritional elements as well as a sustainable off ramp for these members moving forward. Moving to rest of our platform, we must materially improve our digital member journey. We need to eliminate years of accumulated friction and more seamlessly integrate across the solution set. We make it too hard to be a WeightWatchers member today. Our vision is to create a seamless experience that allows members to explore our full range of weight management solutions from behavioral programs to clinical support and community engagement and additional support as we add on services like registered dietitians. Our priority is to integrate and modernize so members can more easily benefit from the full suite of tools the WeightWatchers program has to offer and the results it delivers. All of this is specific to our direct to consumer business. Let me talk about B2B. The emergence of effective clinical solutions is having a profound impact on both employers and payers as demand for access to weight loss medication continues to explode. We believe it's going to be increasingly hard for employers not to offer coverage for weight loss medication given their positive health benefits, particularly as more suppliers enter the markets over time and drive down cost. This represents a clear and growing long term opportunity for WeightWatchers with the breadth and effectiveness of our program, a unique differentiator. Our B2B offering delivers a robust ROI for employers and insurers across all program options with our clinic program achieving nearly a 4 to 1 payback. We're strategically adapting our solutions to meet this evolving market led by Scott Honken, who recently joined us as Chief Commercial Officer. Wrapping up, there's no shortage of opportunity for WeightWatchers today and in the future in the U.S. and abroad. To revert this business to growth, we need to double down on our strengths and the foundation and breadth of our value proposition, which is more relevant today than ever before. We need to obsess about our member experience and leverage our full toolkit, not only its component products. We need to be bold and clear as we engage both with our existing members and potential future customers. At a high level looking forward, we're focused on one, the simplification and integration of our digital experience, creating the ability to move easily in, out and across all we have to offer irrespective of where a member is on their journey, listening to our members and truly building to the power of one WeightWatchers. Two, a revitalization of our brand, clarifying and unifying our apparently disparate marketing messaging, particularly in a world of elevated CAC and prolific competition in the clinical space. Three, continuing to leverage our deep science backed heritage in this new world of GLP-1s, not only in the doctor's office, but as a fully integrated, sustainable and livable solution with our nutritional expertise and community support as crucial differentiators that support maximum results. Four, partnering with employers and health plans to help them provide access in an affordable and scalable manner to the tens of millions of employees and members seeking support. And five, innovating and adding to our platform where we see value for both members and our business for the short and longer term. Much of this work will take time. And as we move forward, the team is taking a disciplined approach to spending and resource allocation, recognizing that some initiatives will need to be sequenced as we build for 2025 and beyond. We'll move forward thoughtfully, but decisively, balancing near-term performance with investments in our future growth opportunities. And with that, let me turn it over to Heather to walk us through the quarter and our outlook in more detail.
