Thank you, Rob. Good morning. We delivered growth in the quarter, led by continued strength in Oncology and Animal Health along with increasing contributions from our diverse and compelling new products across an array of therapeutic areas. Our strong commercial and operational execution continues to drive near-term performance while we invest in our outstanding pipeline to create long-term value for patients, customers and shareholders. Now turning to our second quarter results. Total company revenues were $16.6 billion, an increase of 5% or 4% excluding the impact of foreign exchange. The following revenue comments will be on an ex- exchange basis. In Oncology, sales of the KEYTRUDA family of products which includes KEYTRUDA and KEYTRUDA QLEX, increased 4% to $8.4 billion, with global growth driven by strong uptake in earlier-stage cancers and continued robust demand from metastatic indications. Strong utilization in tumors that primarily affect women, including breast and cervical cancers and increased use of KEYTRUDA in combination with Padcev in locally advanced or metastatic urothelial cancer were key contributors to growth. Sales of KEYTRUDA QLEX were $463 million. We have seen physician and patient adoption increase since the permanent J-code was established in April. As expected, early use has been predominantly in patients who are either on monotherapy or in combination with an oral agent. We remain confident in the trajectory of KEYTRUDA QLEX adoption. Our broader oncology portfolio delivered another quarter of strong growth. WELIREG sales increased 67% to $271 million, driven by continued uptake from international launches and increased use in certain U.S. patients with previously treated advanced renal cell carcinoma. We are excited that certain patients with earlier stage renal cell carcinoma may benefit from adjuvant treatment with WELIREG following the recent FDA approval of LITESPARK-022. In vaccines and infectious diseases, GARDASIL sales were $1.2 billion, an increase of 3%. Sales in international markets grew 6% while the U.S. was roughly flat as lower demand and timing of CDC purchases was largely offset by price. In pneumococcal, CAPVAXIVE sales were $184 million an increase of 40%. Growth was primarily driven by uptake from ongoing launches in certain international markets as well as higher demand in the U.S. In HIV, we are pleased to have launched IDVYNSO, our once-daily oral 2-drug single-tablet regimen of doravirine and islatravir for certain virologically suppressed adults. We have seen encouraging early progress on access and reimbursement and look forward to broadening access over time. In cardiometabolic and respiratory, WINREVAIR global sales were $588 million, an increase of 75%, reflecting continued strong demand from adults with pulmonary arterial hypertension. In the U.S., we saw further progress with more than 1,800 new patients having received a prescription and an increase in the proportion of patients whose background therapies do not include a prostacyclin. Outside the U.S., we continue to progress with ongoing launches. OHTUVAYRE sales were $204 million, reflecting continued prescription demand from patients with COPD as well as the benefit from the timing of specialty pharmacy purchases. Our Animal Health business delivered another quarter of solid growth with sales increasing 5%. Livestock sales grew 6%, driven by higher demand for ruminant and poultry products. Companion animal sales increased 5% due to new product launches. I will now walk you through the remainder of our P&L, and my comments will be on a non-GAAP basis. Gross margin was 81.1%, a decrease of 1.1 percentage points, primarily due to higher inventory reserves. Operating expenses increased to $12.6 billion. There was a $5.7 billion charge for the acquisition of Terns Pharmaceuticals in the quarter compared with a $200 million business development charge a year ago. Excluding these charges, operating expenses grew 7%, reflecting increased investments in support of our launches as well as our robust early and late-phase pipeline, partially offset by benefits from our multiyear optimization effort and recognition of a portion of the external funding for sac-TMT development. Other expense increased to $290 million, primarily reflecting financing costs related to recent business development transactions. Our tax provision was $882 million. As a result of the nontax deductible onetime charge for Terns, our tax rate was 160.3%. Taken together, we reported a loss of $0.13 per share, which includes a onetime charge of $2.31 per share from the acquisition of Terns. Now turning to our 2026 non-GAAP guidance. We have raised and narrowed our full year revenue guidance range to be between $66.3 billion and $67.3 billion, representing growth of 2% to 4%, including a positive impact from foreign exchange of approximately 1 percentage point using mid-July rates. Gross margin is now assumed to be approximately 81%, reflecting higher inventory reserves. Operating expenses are expected to be between $42 billion and $42.7 billion. This range includes $5.8 billion for the upfront charge for Terns and investment to advance MK-4208. This guidance does not assume additional significant potential business development transactions. Other expense, which now includes the financing costs for Terns, is expected to be approximately $1.4 billion. We now expect a full year tax rate between 35% and 36%, which reflects the nontax deductible onetime charge for Terns. We assume approximately 2.48 billion shares outstanding. Taken together, we expect EPS of $2.66 to $2.76 with a midpoint of $2.71, including a positive impact from foreign exchange of approximately $0.15 using mid-July rates. This range also includes an upfront charge of $2.31 per share related to the acquisition of Terns as well as approximately $0.12 per share of ongoing costs to advance MK-4208 and finance the transaction. As you consider your models, there are a few items to keep in mind for the second half of the year. First, for OHTUVAYRE. We remain excited about OHTUVAYRE's strong clinical profile and look forward to achieving its multibillion-dollar commercial potential in the coming years. Third quarter sales will be impacted by the unwind of specialty pharmacy purchases in the second quarter. We continue to invest behind our sales force and promotion to reach more physicians and patients in the U.S. We are also working with our specialty pharmacies to improve patient experience. We expect these actions to lead to accelerated growth in 2027. Next, we anticipate that total U.S. KEYTRUDA year-over-year growth will moderate as we increasingly reach peak penetration across several key indications. Additionally, as a reminder, we benefited by approximately $250 million due to the timing of wholesaler purchases in the third quarter of 2025, which will not repeat this year. For BRIDION, U.S. sales are anticipated to decline at a slower pace than previously expected due to lower-than-anticipated generic competition. Finally, other revenue in the second half of 2026 is expected to be significantly higher than the second half of 2025. This increase is primarily due to our revenue hedging program as well as an expected milestone receipt in the fourth quarter related to an out-license agreement. Now turning to capital allocation, where our strategy remains unchanged. We will continue to prioritize investments that support near- and long-term growth, including our new product launches and robust pipeline. We remain committed to the dividend with the goal of increasing it over time. Business development remains a high priority, and we maintain the ability within a strong investment-grade credit rating to pursue additional science-driven, value-creating transactions. We are on pace for approximately $3 billion in share repurchases this year, as previously communicated. To conclude, as we enter the second half of the year, we remain confident in the outlook of our business, supported by global demand for our innovative medicines and vaccines, including our many new product launches. The transformation of our portfolio is underway, and we are well positioned to deliver value for patients, customers and shareholders now and into the future. With that, I'd like to turn the call over to Dean.
