Thank you, Brian, and good afternoon. I'm pleased to report another quarter of strong execution and financial performance exceeding our expectations, reflecting the strength of our diversified health care platform. My comments today will refer to our adjusted results. I'll begin with our second quarter fiscal 2026 performance, followed by an update on our fiscal 2026 outlook. As previewed at our Investor Day in September, we implemented a new reporting structure beginning in the second quarter to enhance transparency and sharpen visibility into our growth platforms. This framework highlights the differentiated capabilities within our oncology and multispecialty and biopharma services platforms, verticals where McKesson is best positioned to deliver sustainable long-term growth. This realignment reinforces our commitment to disciplined execution, strengthens our strategic focus and accelerates long-term value creation for all stakeholders. Turning now to results for our second quarter. McKesson delivered another strong quarter, achieving record quarterly revenues of $103 billion, an increase of 10% compared to the prior year, driven by robust performance across our portfolio of businesses. Growth was led by the North American Pharmaceutical segment, reflecting increased prescription volumes from retail national account customers and by the Oncology and multispecialty segment, supported by expanded distribution of oncology and multispecialty products and contributions from recent acquisitions. Gross profit increased 9% to $3.5 billion, primarily due to strong specialty distribution and provider growth within the Oncology and Multispecialty segment. Operating expenses decreased 1% to $2 billion, reflecting divestitures in our Canadian business and disciplined cost optimization initiatives in the Medical-Surgical Solutions segment. These reductions were partially offset by continued investment in the Oncology and Multispecialty segment, including acquisitions completed in the first quarter of fiscal 2026. Our unrelenting focus on cost discipline and operational efficiency, powered by a technology-first mindset and AI-driven modernization continues to create value for all stakeholders. This progress is evident again in the second quarter. Operating expenses as a percentage of gross profit declined 570 basis points, delivering significant operating leverage as we accelerate and modernize our operations. Operating profit reached a quarterly record of $1.6 billion, an increase of 26% year-over-year, reflecting growth across all operating segments. This strong performance was driven by increased specialty distribution volumes in both the Oncology and Multispecialty and North America Pharmaceutical segments, increased demand for access solutions in our Prescription Technology Solutions segment and continued benefits from cost optimization initiatives in the Medical-Surgical Solutions segment. The acquisitions of PRISM and Core Ventures in the Oncology and Multispecialty segment contributed approximately 6% to year-over-year growth. Additionally, the sale of an equity investment and market decisions within the U.S. oncology network contributed approximately 4%. Excluding these 2 items, organic growth was approximately 16% in the quarter, underscoring the strength and momentum of our core business. Interest expense declined 6% to $68 million, resulting from effective cash and portfolio management, including our derivative portfolio. The effective tax rate was 17.5% compared to 21% in the prior year. In the second quarter of fiscal 2026, we recognized net discrete tax benefits of $96 million, primarily related to the release of a valuation allowance compared to net discrete tax benefits of $44 million in the second quarter of fiscal 2025. Second quarter diluted weighted average shares outstanding was 124.4 million, a decrease of 4%. Second quarter earnings per diluted share increased 39% to $9.86, driven by several key factors. Robust core operational performance, contributions from the first quarter acquisitions of PRISM and Core Ventures in our Oncology and Multispecialty segment, approximately $0.30 or 4% from net gains related to the sale of an equity investment and market decisions within the U.S. Oncology Network in our Oncology and Multispecialty segment and a lower effective tax rate. Turning to second quarter segment results, which can be found in Slides 8 through 12 and starting with North American Pharmaceutical. Revenues were $86.5 billion, an increase of 8%. This growth reflects a continuation of solid pharmaceutical utilization, including higher volumes from retail national account customers and specialty products. Our ongoing focus on operational excellence also delivered operating expense leverage during the quarter. Revenues from GLP-1 medications were $13.2 billion in the quarter, an increase of approximately $2.6 billion or 24% when compared to the prior year. On a sequential basis, GLP-1 revenue increased 6%. Segment operating profit increased 13% to $851 million, driven by growth in the distribution of specialty products to health systems, the impact of new product launches and continued operating expense efficiencies. In the Oncology and Multispecialty segment, revenues increased 32% to $12 billion, driven by strong provider and specialty distribution growth, including contributions from acquisitions completed in the first quarter of fiscal 2026. The acquisitions of PRISM and Core Ventures contributed approximately 12% of the second quarter segment revenue growth. Operating profit increased 71% to $397 million, driven by increased provider and specialty distribution volumes and contributions from the acquisitions of PRISM and Core Ventures. These acquisitions contributed approximately half of the segment operating profit growth in the quarter. Second quarter operating profit results also included nonrecurring net gains of $51 million from the sale of an equity investment in market decisions within the U.S. Oncology Network. Excluding the impact from the acquisitions of PRISM and Core Ventures and nonrecurring net gains, segment organic operating profit increased 13%, highlighting the strength and momentum of the core business. In the Prescription Technology Solutions segment, revenues increased 9% to $1.4 billion, driven by increased prescription volumes across our third-party logistics and technology services businesses. Operating profit rose 20% to $261 million, reflecting increased demand for access solutions, including prior authorization services for GLP-1 medications. Turning to Medical-Surgical Solutions. During the second quarter, we observed softer illness season product demand compared to the prior year, including vaccines and testing and lower volumes across ambulatory and extended care settings. Revenues were $2.9 billion, flat compared to the prior year. Higher volumes of Specialty Pharmaceuticals were offset by lower contributions from illness season products and testing across the ambulatory and extended care settings. Compared to the prior year, revenues from seasonal vaccines and testing volumes represented an approximate 4% headwind. Operating profit increased 2% to $249 million, driven by operational efficiencies from cost optimization initiatives. This was partially offset by the headwind from lower contributions related to illness seasoned products and testing. Wrapping up our review with corporate. Corporate expenses were $151 million in the quarter. As a reminder, in the second quarter of fiscal 2025, we recorded pretax losses of $15 million or $0.09 per share related to equity investments within the McKesson Ventures portfolio compared to gains of $3 million or $0.02 per share in the second quarter of fiscal 2026. Excluding these impacts, corporate expenses were flat compared to the prior year. Let me turn to cash and capital deployment for the second quarter, as shown on Slide 13. We ended the quarter with $4 billion in cash and cash equivalents, underscoring the strength of our strong liquidity position and capacity to deploy capital in a value-creating manner. Second quarter free cash flow was $2.2 billion, which included $196 million in capital expenditures. This robust cash flow performance reflects disciplined working capital management and continued operating execution strength. During the quarter, we returned $907 million of cash to shareholders, which included $818 million of share repurchases and $89 million in dividend payments. These actions underscore our commitment to balanced capital deployment and long-term shareholder value creation. Before reviewing our updated fiscal 2026 outlook, I'd like to provide 2 portfolio updates. At Investor Day in September, we reaffirmed McKesson's long track record of consistent financial performance driven by strategic clarity, consistency and disciplined execution. Our new segmentation reflects the portfolio evolution, leading to sharper strategic focus, enhanced transparency and increased long-term financial targets. Our strategic clarity and execution have positioned the company to deliver sustained value across multiple environments and different cycles of health care, leading to sustained value creation. Let me start with Norway. Our fiscal 2026 outlook contemplates contributions from operations in Norway for the full fiscal year. Beginning in the second quarter of fiscal 2026, we discontinued recording depreciation and amortization on the assets involved in the transaction due to held-for-sale accounting treatment. This resulted in an accretive impact of $0.03 in the second quarter. For the full year, we now anticipate approximately $0.13 of adjusted earnings accretion due to held for sale accounting in fiscal 2026, which compares to our prior guidance of $0.20. Next, we're committed to executing the separation of our Medical-Surgical Solutions business in a tax-free transaction, maximizing shareholder value. Since it was announced in May, we've made significant progress towards establishing the Medical-Surgical business as an independent operating company. As I mentioned at Investor Day, we anticipate exiting the business by way of an initial public offering. Following a customary lockup period, McKesson intends to exit its remaining interest through a spin-off or a split-off transaction or potentially a combination of both. We currently anticipate that this separation could be completed by the second half of calendar 2027, subject to market conditions and customary regulatory approvals. Our fiscal 2026 outlook assumes 100% ownership of the Medical segment. Our portfolio transformation has delivered consistently outstanding financial results, growth and returns to shareholders. Now moving to our fiscal 2026 outlook. Our strategy continues to deliver outstanding results, propelled by the growth and differentiation of our oncology, multispecialty and biopharma services platforms. These platforms are supported by a durable foundation of distribution assets and capabilities, positioning McKesson for sustained success. At our Investor Day, we raised our earnings per diluted share outlook by $0.80 to a range of $38.05 to $38.55, which was a testament to the clarity of our strategy, strength of our portfolio and disciplined execution. Building on our strong second quarter performance and continued confidence in our outlook over the remainder of the year, we're further increasing our fiscal 2026 earnings per diluted share outlook by $0.30 to a new range of $38.35 to $38.85, which represents 16% to 18% growth over the prior year. This update builds on the $0.80 increase announced at Investor Day in September. For fiscal 2026, we anticipate revenue growth of 11% to 15%, reflecting growth across all core businesses and operating profit growth of 12% to 16%, driven by continued momentum and execution. Let me start with a review of our segments. In the North American Pharmaceutical segment, our core pharmaceutical distribution operations continue to demonstrate a strong and diversified value proposition to customers. We anticipate revenue to increase 10% to 14%, and we're increasing our guidance for operating profit to 5% to 9% growth. The increased operating profit outlook is driven by solid utilization trends, volume growth and continued strong specialty distribution expansion. In the core distribution business, we also anticipate continued growth of GLP-1 medications. We anticipate this growth may vary from quarter-to-quarter. And as a reminder, prior year results include the impact of the divestiture of our Canada-based Rexall and Well.ca businesses at the end of the third quarter of fiscal 2025. In the Oncology and Multispecialty segment, we anticipate revenue growth of 27% to 31% and operating profit growth of 49% to 53%. The guidance includes the acquisitions of PRISM Vision and Core Ventures completed in the first quarter of fiscal 2026. We're pleased with the performance of these acquisitions. We anticipate that they'll contribute approximately 30% to 34% to the fiscal 2026 operating profit growth in the segment. Our full year outlook reflects the impact of these acquisitions and strong organic specialty distribution volume growth. Our oncology and multispecialty platform continued to deliver across distribution, practice management, data and analytics and clinical research. In the Prescription Technology Solutions segment, we anticipate revenues to increase by 9% to 13%, and we are increasing the operating profit outlook to 13% to 17% growth. The improved operating profit outlook reflects strong organic volume growth and momentum across our access and affordability solutions, particularly higher contribution from prior authorization services, including those related to GLP-1 medications. As I've previously discussed, the revenue and operating profit trajectory in this segment is not linear. It may vary from quarter-to-quarter, driven by several factors, including utilization trends, the timing and trajectory of new product drug launches, the evolution of a product's program support requirements as it matures, which could result in a shift to other services or a program termination, product delays and supply shortages, payer requirements, including utilization management and formulary strategies, the annual verification programs that we provide for our customers that occur in our fiscal fourth quarter and the size and timing of investments to support and expand our product portfolio. Moving to the Medical-Surgical Solutions segment. Due to lower-than-anticipated illness season product volumes compared to the prior year, including vaccines and testing and lower volumes across ambulatory and extended care settings, we anticipate revenue and operating profit at the low end of 2% to 6% growth. Illness season variability remains a key factor and the timing and severity level of each illness season can drive variability from quarter-to-quarter and year-to-year. We anticipate corporate expenses to be in the range of $600 million to $650 million, which incorporates the impact of $4 million of pretax gains related to equity investments within the McKesson Ventures portfolio in the first half of the fiscal year. Turning now to items below the line. We anticipate interest expense to be in the range of $210 million to $240 million. Reduced interest expense target compared to the range provided at Investor Day reflects continued strong debt portfolio management and commitment to maintaining our strong investment-grade credit ratings. We anticipate income attributable to noncontrolling interest to be in the range of $215 million to $235 million, which includes the impact from fiscal 2026 acquisitions. And we anticipate the full year effective tax rate will be in the range of 18% to 19%. We also anticipate that the quarterly tax rate will be higher in the third quarter than in the fourth quarter due to the timing of discrete tax items. We anticipate the third quarter tax rate to be in the range of 23% to 25%, wrapping up our outlook with cash flow and capital deployment. One of McKesson's enduring strengths is our proven ability to consistently generate strong free cash flow and execute value-creating capital allocation. For fiscal 2026, we anticipate free cash flow of approximately $4.4 billion to $4.8 billion. Our outlook includes plans to repurchase approximately $2.5 billion of shares with estimated weighted average diluted shares outstanding of approximately 124 million. Our strong operating performance, combined with disciplined working capital management continues to provide ample liquidity and financial flexibility. We've also strengthened our financial position by reducing leverage and optimizing our debt portfolio over time. Our focused and disciplined approach to capital allocation remains a cornerstone of our strategy and a key driver of long-term shareholder value creation. In summary, McKesson delivered strong second quarter results, including record quarterly consolidated revenue and double-digit operating profit growth across 3 segments. Our updated earnings per diluted share range of $38.35 to $38.85 reflects both our second quarter results and our confidence in the business for the remainder of fiscal 2026 as we continue to execute against our strategic and financial framework. The ongoing evolution of our portfolio is aligned with the increased long-term targets that we committed to, and this transformation continues to translate into stronger earnings, higher returns on invested capital and a fortress balance sheet, positioning McKesson for disciplined and strategic capital deployment. And with that, let's move to the Q&A session.
