Good morning, and thank you for joining us. Let me start by directly addressing our revised full year outlook. We know this adjustment is disappointing, and we're taking concrete actions to address it. Our focus is on execution, making the right decisions now to strengthen the business and position Elevance Health for long-term sustainable performance. Our strategy remains grounded in delivering whole health solutions that are simple, affordable and personalized. While the external environment continues to evolve, we are focused on the areas within our control. managing cost, deploying targeted investments and reinforcing the operational foundation that supports long-term value creation. In the second quarter, we delivered adjusted EPS consistent with our expectations. These results reflect continued strength in our Medicare Advantage portfolio and disciplined cost management across key parts of the business as we navigate evolving dynamics in the ACA and Medicaid markets. Our Carillon platform continues to drive growth. Carelon Rx is gaining traction in the market with its integrated medical pharmacy offering and Carelon Services delivered strong results with CareBridge scaling rapidly across dual eligible and high-acuity Medicaid populations. As I mentioned at the start of the call, we are revising our full year 2025 adjusted EPS guidance to approximately $30. This reset reflects the same pressures that others in the sector have now confirmed, particularly elevated medical cost trends across ACA and slower-than-expected Medicaid rate alignment. Importantly, this decision is anchored in our view that the elevated trends we are now observing will persist and reflects our updated visibility into the second half of the year. It is not based on assumptions of a near-term recovery. We are choosing to act now, not later to ensure our outlook reflects prevailing conditions and to give investors clear visibility. We believe this step positions us to execute with discipline and begin rebuilding long-term margin stability that will empower our future growth. Looking ahead, we're executing against a clear strategy focused on strengthening structural performance across the enterprise. We're advancing our efforts to stabilize trends, particularly in high-cost areas like specialty services, post-acute care and certain outpatient settings. Our programs focused on ensuring the right care in the right setting grounded in safety, quality and outcomes. In support of our commitment to simplify care delivery, we've significantly streamlined our prior authorization processes with over half of electronic requests now processed in real time, and fewer requirements for high-performing providers. Our AI-enabled tools such as Health OS and intelligent clinical assist helps streamline clinical workflows and accelerate routine approvals by surfacing relevant data. All medical decisions requiring clinical judgments are reviewed by licensed professionals with independent oversight to ensure care is appropriate, consistent and aligned with our commitment to quality. We're also using advanced analytics to identify fraud, waste and abuse, enabling us to intervene where patterns deviate from clinical and billing standards, reinforcing system integrity while protecting appropriate access to care. Our value-based care portfolio continues to expand particularly in behavioral health and oncology. More than 1/3 of our benefit expense is now in downside risk arrangements, supporting improved care coordination and cost predictability. Through Carelon, we're scaling these capabilities across Elevance Health and with external clients, helping to drive better outcomes for complex and chronic populations. Importantly, these are not future state aspirations, they are embedded in our operations today and form the core of our multiyear plan to stabilize margins and build sustainable earnings power. While it is still early to provide an initial outlook for 2026, the actions we're taking are designed to stabilize trend, improve pricing alignment and restore operating leverage over time. In ACA, we've already repriced products for rising cost intensity. We also expect a broader market reset in 2026 as the scheduled expiration of enhanced subsidies drives further risk call changes, and our position reflects early disciplined action. In Medicaid, we're proactively engaged with state partners to ensure that upcoming rate cycles continue to reflect the developing acuity environment. While rate recovery has lagged current cost levels, we expect a meaningful catch-up as utilization data becomes more actionable. In commercial, we're maintaining a disciplined approach to pricing, ensuring our renewals and network contracts are aligned to the trend environment. And in Medicare Advantage, we bid with discipline with a focus on margin normalization supported by stable utilization and Carelon- led clinical programs. These steps combined with our structural cost levers and care management, payment integrity and value-based care delivery are designed to improve visibility and consistency as we move through 2025 and into the next phase of growth. We recognize that revising guidance for the second consecutive year is disappointing, and we remain committed to transparency and strong execution as we continue to navigate unprecedented cost trend affecting multiple lines of business. We're taking this step to reflect what we can control, sharpening our execution, focusing our investments and strengthening the core drivers that will support a more durable and sustainable future, and this would not be possible without the dedication of our nearly 100,000 associates that amplify our impact every day. We remain confident in the strength of our enterprise, the impact of our investments and our ability to create long-term value through operational discipline, innovation and our commitment to whole health transformation. With that, I'll turn it over to Mark to walk through the financials. Mark?
