Thank you, Mark, and thank you for joining us today. This morning, we announced second quarter results that were below expectations and also lowered our financial outlook for the remainder of 2025. Before I go into the broader steps that we are taking to diversify our business and establish a new growth trajectory for the company, I want to drill down on PYLARIFY and the current dynamics in the PSMA PET market. In the back half of the quarter, the confluence of MUC-based reimbursement and aggressive discounting by what had been a somewhat dormant F-18 competitor, led some economically sensitive customers to reassess their choice of PSMA agents. This led to the renegotiation of some existing strategic partnerships as well as a conscious decision to walk away from those volumes at certain accounts that requested pricing terms that were not in the long-term interest of our PSMA PET franchise. PYLARIFY also continues to be concentrated in large institutions that due to constraints continued to grow at a slower rate than the overall market. However, our strategic partnership agreements have proven and will continue to prove effective at retaining the vast majority of our customers, who recognize PYLARIFY's clinical differentiation. This is reflected in our U.S. quarterly volume growth, 2% year-over-year and over 4% sequentially. Paul will provide greater detail, but I want to be clear, we understand the dynamics that we faced during the quarter, how we expect these dynamics to evolve in the second half of the year, and how these changes impact our business. We have implemented actions to ensure we maintain our market leadership and maximize the long-term value of the franchise. These actions include conducting a continuous and comprehensive review of our customer base. Expanding our strategic partnerships to the smaller, high-growth accounts, enhancing our availability and geographic reach, proactively communicating the value proposition of PYLARIFY and our growing innovative radiopharmaceutical portfolio, including Neuraceq and executing a disciplined pricing strategy. Lantheus has a leading role in the prostate cancer market and our strategy and actions will enable the sustained growth and success of this franchise. Underscoring the value of this franchise, we announced today that the FDA has accepted our NDA for a new formulation of PYLARIFY, which will increase batch size by approximately 50%, enabling increased patient access, supply resilience and enhanced production efficiency all to the benefit of our customers and patients. Our prostate cancer franchise will be further enhanced in the long term by the development of LNTH-2401 and 2402, our GRPR, radio diagnostic and radio therapeutic product candidates. Part of our decision to remain disciplined with our pricing is to preserve the value of our PSMA PET franchise in anticipation of launching our new PSMA PET agent. If approved, we believe it will be eligible for three years of transitional pass-through payment status and will reinvigorate growth. Fundamental differences in the chemical structure of PSMA PET imaging agents significantly influence their performance. For example, we have heard first half from HCPs they have begun to see increasing numbers of false positives in recurrent patients from their real-world use of competing F-18 agent, which, while anecdotal, is a risk specifically called out in their package insert. And with respect to Gallium, the shorter half-life, lower positron yield and lower spatial resolution are well known. Beyond PYLARIFY, we continue to advance our strategy to diversify our portfolio and build talent and capabilities needed to lead at all stages of the radiopharmaceutical value chain. The acquisitions of Evergreen on April 1st to Life Molecular on July 21st, add complementary capabilities, bring immediate growth drivers, expand our pipeline and importantly, diversify our revenue, positioning us for long-term growth. We grew our neurology franchise with the addition of Neuraceq, our globally approved F-18 PET imaging agent used to detect beta amyloid plaques in patients evaluated for Alzheimer's disease. In June, the FDA approved an expanded label for Neuraceq, enabling broader diagnosis, selection and monitoring of appropriate patients for amyloid-targeting therapies. This broader label, combined with the continued adoption of Alzheimer's therapeutics and advancements in therapeutic development programs reinforces our belief in the significant growth potential of the U.S. Alzheimer's disease PET imaging market. One, we estimate could exceed $1.5 billion by the end of the decade and reach approximately $2.5 billion by the mid-2030s. In fact, the recent AAIC meeting highlighted a number of therapeutic programs rapidly advancing in the clinic. Most of the more promising programs already incorporate at least one of our amyloid or tau tracers for selection criteria of monitoring and follow-up. Looking ahead to the next 18 months, we expect to further expand our commercial portfolio and diversify our revenue streams with the launch of four additional radiopharmaceutical products, including our new F-18 PSMA PET formulation, MK-6240, our late-stage tau-targeted radio diagnostic for Alzheimer's disease as well as OCTEVY and PNT2003, our registrational stage radio diagnostic and therapeutic for neuroendocrine tumors. Taken together, we believe these strategic moves will solidify our position as the partner of choice for nuclear medicine and certainly drive future growth. To underscore our confidence in our longer-term strategy and our ability to execute, the Board has authorized a new $400 million stock repurchase program. This decision reflects our belief in the intrinsic value of the business and our commitment to deliver shareholder returns. It also signals our conviction in the strength of our pipeline, our significant free cash flow generation and the durability of our financial position. By repurchasing shares, we are not only optimizing capital allocation, but also reinforcing our confidence in the future. I will now turn the call over to Paul to discuss the market dynamics and the actions we're taking in more detail. Paul?
