Thank you, Mark, and good morning, everyone. This morning, we reported our third quarter financial results and reaffirmed our full year guidance. 2025 has been a dynamic year for the ACA marketplace. We've observed higher average market morbidity attributable to strong ACA growth from Medicaid redeterminations and ACA program integrity efforts that were implemented after the completion of 2025 pricing. We have taken disciplined actions to manage costs this year and to position us to ensure we return to profitability next year. Turning now to third quarter results. Total revenue increased 23% year-over-year to approximately $3 billion, driven by higher membership. We ended the quarter with 2.1 million members, an increase of 28% year-over-year. Membership growth was driven by solid retention, above-market growth during open enrollment and SEP member additions. The third quarter medical loss ratio was 88.5%, an increase of approximately 380 basis points year-over-year. We received a risk adjustment report in the third quarter for claims through July, which showed a further increase in market morbidity across several states. The third quarter MLR was impacted by a $130 million increase to our risk adjustment payable for 2025, partially offset by $84 million of favorable prior period development, primarily related to claims run out from the prior year. As discussed during our second quarter earnings call, we observed a sequential decrease in utilization each month throughout the second quarter. This trend persisted into early 3Q before stabilizing to be more in line with our expectations. Overall year-to-date utilization is modestly above our expectations. By category, inpatient utilization remained elevated but moderated meaningfully throughout the first 9 months of the year. Outpatient and professional were slightly elevated, while pharmacy remained favorable. Switching to administrative costs. We continue to deliver strong improvements in the SG&A expense ratio. The third quarter SG&A expense ratio improved by approximately 150 basis points year-over-year to 17.5%. The year-over-year improvement was driven by fixed cost leverage, lower exchange fee rates and disciplined cost management, partially offset by the impact of higher risk adjustment payable as a percentage of premium. In the third quarter, the loss from operations was $129 million, a change of $81 million year-over-year, and the net loss was $137 million, an $83 million change year-over-year. The adjusted EBITDA loss was $101 million in the quarter, a change of $90 million year-over-year. Shifting to the balance sheet. We have taken opportunistic steps to strengthen our capital position and optimize our capital structure. During the third quarter, we completed a $410 million convertible notes offering due 2030. Net proceeds were $360 million, inclusive of the cost of a capped call transaction, which increased the effective conversion price to $37.46. In addition, subsequent to quarter end, we entered into an agreement to redeem the vast majority of our outstanding $305 million convertible senior notes for shares. We ended the third quarter with approximately $4.8 billion of cash and investments, including $541 million of cash and investments at the parent. As of September 30, 2025, our insurance subsidiaries had approximately $1.2 billion of capital and surplus, including $564 million of excess capital. Turning now to 2025 full year guidance. Based on our results through the first nine months of the year, we are reaffirming all of our guidance metrics. For total revenue, we now expect to be towards the low end of our guidance range of $12 billion to $12.2 billion, driven by the third quarter ACA Marketplace morbidity that increased by more than our prior estimates. Membership growth has been strong through the first nine months of 2026.For the fourth quarter, our outlook contemplates a sequential decline in membership, driven by more historical churn patterns as the continuous monthly SEP for those at or below 150% of federal property level ended in the beginning of September. Our outlook also assumes risk adjustment as a percentage of direct and assumed policy premiums is in the high mid-teens range. Shifting to the medical loss ratio. We continue to expect a full year MLR in the range of 86.0% to 87.0%. The full year MLR guidance reflects higher average market morbidity, year-to-date utilization patterns and continues to assume a modest increase in utilization in the fourth quarter as members may seek additional care ahead of anticipated coverage changes next year. On administrative expenses, we continue to expect an SG&A expense ratio in the range of 17.1% to 17.6%, driven by greater operating leverage and variable cost efficiencies. We expect a loss from operations in the range of $200 million to $300 million and an adjusted EBITDA loss of approximately $120 million less than the loss from operations. While the third quarter risk adjustment true-up is expected to drive total revenues towards the low end of our full year guidance range, favorable prior period and in-year claims development and administrative expense efficiencies substantially offset the impact. So net-net, our outlook for the loss from operations remains unchanged. Now I'll spend a moment on our planning assumptions for 2026. While it is too early to provide formal guidance, we have taken appropriate actions to ensure we can deliver meaningful margin expansion and return to profitability next year. Our 2026 pricing strategy balanced growing market share and improving profitability. As Mark mentioned, our weighted average rate increase is approximately 28% for 2026. This increase anticipates above-average trend and is significantly higher market morbidity driven by increased market morbidity in 2025, the expiration of enhanced premium tax credits and the current ACA program integrity initiatives. We believe our disciplined pricing strategy captures the changing market conditions we've observed this year and the expected changes next year. Based on a review of final rates, our competitive positioning is in line with our expectations, and we are confident in our ability to profitably grow market share next year. As previously mentioned, we also took actions to eliminate approximately $60 million in administrative costs for 2026. In closing, we remain committed to bringing consumers affordable, innovative products and building an even larger ACA market over the long term. 2025 is a reset for the ACA marketplace. We've taken necessary pricing and cost actions and are confident in our ability to meaningfully expand margins and return to profitability in 2026. With that, I will turn the call over to the operator for the Q&A portion of the call.
