Thank you, Martina, and good morning, everyone. Starting with Slide 16. Our financial results underscore our market leadership and the strength of our execution in the fourth quarter. We finished 2025 with strong momentum in our subscription businesses and encouraging signs in the market backdrop for 2026. All of this reinforces our confidence in the medium-term financial targets we laid out at our recent Investor Day. Ratings and Indices each posted double-digit growth during the quarter, driven by robust debt issuance and equity market appreciation inflows enabling us to make strategic incremental investments in key growth areas across the enterprise. We're also pleased with our strong subscription growth in both Market Intelligence and Energy. Reported revenue grew 9% and our organic constant currency revenue rose 8%. Continued expense discipline allowed us to make important strategic investments in the fourth quarter while still expanding margins. Adjusted expenses increased 8% resulting in 60 basis points of year-on-year margin expansion to 47.3%. As you'll recall, we divested the OSTTRA joint venture in early October. And if we exclude the contribution from OSTTRA in 2024 as well, margin expansion would have been 130 basis points year-over-year. We delivered 14% growth in adjusted diluted EPS in the quarter, resulting in full year EPS at the higher end of our most recent guidance range and well above the initial guidance range we provided last February. While our tax rate for the full year was within our guidance range, it did come in a bit above our internal expectations and near the high end of guidance. Had our tax rate come in at the midpoint of guidance, EPS would have been approximately $0.08 higher. Now turning to our key strategic investment areas on Slide 17. Private Markets revenue grew 16% year-over-year driven primarily by the Ratings and Market Intelligence divisions. Ratings was the largest contributor to that growth, underscoring continued strong demand for debt Ratings, private credit analysis and credit estimates in the private credit market. Energy Transition and Sustainability revenue decreased 3% to $101 million in the quarter. This decline was not entirely unexpected and reflects the ongoing uncertainties that have led many customers to slow spending in this area, particularly in consulting engagements and onetime transaction spend in certain geographies. While we remain confident in the long-term growth of this important initiative, our outlook for 2026 does not depend on a meaningful recovery in the near term. Turning to Vitality. As we build on the new products, features and enhancements that were highlighted earlier, I'm pleased to report we generated $470 million in Vitality revenue in the fourth quarter and continue to deliver a Vitality Index of 12%. Going forward, while we do not intend to provide explicit disclosures on these metrics in this particular format. We will continue to provide investors with timely updates on the progress we make both qualitatively and quantitatively. Turning to our divisions on Slide 18. Market Intelligence reported revenue grew 7%, and organic constant currency revenue grew 5% in the fourth quarter. Subscription revenue, which constitutes roughly 85% of Market Intelligence grew approximately 7%, both organically and as reported. Onetime revenue and volume-driven revenue were flattish in aggregate in the quarter. Subscription revenue growth remains the single most important indicator of the health and execution of Market Intelligence, and we are very pleased with the results the team delivered. Data Analytics and Insights reported revenue growth of 7%, which included a $9 million revenue contribution from the With Intelligence acquisition. The performance was anchored by robust subscription sales of Capital IQ Pro and Visible Alpha. Credit & Risk Solutions revenue growth was 10%, driven by strong subscription sales of Ratings Express. We also benefited from some upfront revenue recognition tied to a major renewal in the Financial Risk Analytics product group, which lifted growth above what we had seen in the first 3 quarters. Enterprise Solutions posted 4% revenue growth, which includes a 2 percentage point headwind from EDM and thinkFolio, both of which saw declines year-over-year in the fourth quarter. Wall Street Office, its manager and corporate actions all supported the underlying revenue growth across this part of our MI franchise. However, we did see a slowdown in our volume-driven products in the quarter that are tied to capital markets activity. This activity provided a tailwind to recurring variable revenue growth in the first 3 quarters of the year, but in this quarter. Adjusted expenses increased 7% year-over-year driven by higher compensation expense, additional long-term strategic investments and higher-than-expected expenses from With Intelligence given the accelerated close, partially offset by ongoing productivity initiatives. This resulted in a 32.2% operating margins in Market Intelligence for the quarter. Given the sales outperformance we experienced in our market-driven businesses, both Ratings and Indices, we chose to pull forward some of our 2026 investments in Market Intelligence beyond what was contemplated in our latest 2025 guidance. Without the incremental investments in the quarter and earlier than expected close of the With Intelligence acquisition, MI's margin would have been approximately 80 basis points higher in the fourth quarter and 20 basis points higher for the full year. Now turning to Ratings on Slide 19. We Ratings revenue increased 12% year-over-year or 10% on an organic constant currency basis. The increase was balanced across both transaction and non-transaction revenue streams, underscoring the breadth of our market coverage. Transaction revenue grew 12% in the fourth quarter, driven primarily by strong issuance volumes and investment grade. While we also saw a healthy growth across high yield, structured finance and governance, we did see a low double-digit decline in Billed Issuance from bank loans. That mix shift out of high-yield and bank loans and into investment grade created an unusually large gap between Billed Issuance growth of 28% and transaction revenue growth of 12%. Nontransaction revenue increased 11%, driven primarily by higher annual fee revenue from Surveillance. We also saw a very strong growth in CRISIL, and we nearly tied last quarter's record in Ratings Evaluation Services revenue. Adjusted expenses increased 6% reflecting higher compensation costs and continued strategic investments in our people, technology and product development. This contributed to the division's 210 basis points of margin expansion to 61.8%. Now turning to S&P Global Energy on Slide 20. Energy revenue grew 6% in the fourth quarter, driven by continued strength in energy resources, data and insights and price assessments. We continue to see very strong demand for our subscription offerings, including Platts benchmarks and our differentiated data, research and thought leadership. Sanctions announced in the second half created a $3 million headwind on fourth quarter revenue, which negatively impacted Energy Resources Data and Insights and Upstream Data and Insights revenue. We expect to lap those sanctions by the end of Q3 2026. Energy Resources Data & Insights and Price Assessments grew 9% and 8%, respectively, driven by strength in petroleum gas, power and renewables. Advisory and transactional services revenue decreased by 5% as we continue to see some softness in consulting and events revenue. This was partially offset by double-digit growth in Global Trading Services or higher trading volumes in petroleum, gas and LNG offset the declines in onetime revenues. Upstream Data and Insights revenue increased slightly in the quarter, driven by upfront revenue recognition of certain software renewals. We're continuing to lay the groundwork for our Upstream transformation strategy and see a path towards stabilization in 2026 through a combination of client platform upgrades, expanded distribution partnerships and dedicated specialists in our go-to-market team. However, given the backdrop of lower oil prices and ongoing market uncertainty, it will take several quarters before these management actions will drive growth in Upstream. Adjusted expenses rose 5%, driven by higher compensation costs and ongoing investments in growth initiatives, partially offset by productivity initiatives. Operating profit for the Energy division increased 7% and operating margin expanded by 50 basis points to 45.5%. Now turning to S&P Dow Jones Indices on Slide 21. Revenue grew by 14%, with double-digit growth across all business lines, including asset-linked fees, which benefited from both higher AUM and net inflows. Revenue associated with asset-linked fees grew 13% in the fourth quarter. This was driven by equity market appreciation and strong net inflows into products based on S&P Dow Jones Indices. Exchange-traded derivative revenue was up 20%, driven by strength in SPX ETD volumes. Data and custom subscriptions increased 13% year-over-year, driven by new business growth in contracts and included a roughly 2 percentage point contribution from revenue related to the ARC Research acquisition. Adjusted expenses were up 11% year-over-year, driven by higher compensation costs and investments in growth initiatives. Indices operating profit grew 16% and operating margin expanded 90 basis points to 68.8%. Now turning to Mobility on Slide 22. Revenue grew 8% year-over-year with double-digit growth in dealer and financials and other. Customers continue to rely on the unique data and solutions from CARFAX, driving strong subscription growth despite a complicated environment for automotive OEMs. Dealer revenue increased 10% year-over-year owing to the healthy new customer growth in both CARFAX and automotiveMastermind. Manufacturing revenue grew 1% year-over-year as tariffs and regulatory uncertainty weighed on demand for consulting and lower recalls. Financials and other increased 11% as the business line continues to benefit from strong underwriting volumes and commercial momentum. Adjusted expenses grew 7%, driven by continued advertising and promotional investment, partially offset by the lapping of elevated incentive compensation last year. Mobility's operating margin expanded 70 basis points year-over-year to 35.4%. Before I move on to our guidance for 2026, I'd like to provide you with an update on our planned spin of the Mobility business on Slide 23. We have made significant progress against our separation plan, and we are excited to announce at the NADA conference last week that we've chosen Mobility Global as the name of the new soon-to-be independent company. Since our last earnings call, we have also confidentially filed the Form 10 with the SEC completed the senior leadership appointments, including naming Matt Calderone as CFO designate. Looking ahead, our next major milestones are well defined. We will continue to make progress in the separation process for the first quarter. In the second quarter, we expect to file our Form 10 publicly and the Mobility global team expects to host an Investor Day and launch its equity roadshow. We also expect to launch a public debt offering for Mobility at some point in the second quarter, targeting an investment-grade rating. From a financial reporting and guidance perspective, S&P Global will continue to fully consolidate Mobility Global in our financial statements and 2026 guidance until the separation is complete. We also want to ensure investors have clear comparability in a transparent view of S&P Global's post-separation financial profile. Upon completion of the spin, we intend to provide recast financials for the 4 quarters of 2025 and any 2026 periods reported, adjusted to exclude Mobility's contribution along with other relevant adjustments as outlined at our Investor Day. We also expect to issue updated 2026 financial guidance at that time, excluding Mobility. Now turning to guidance on Slide 24. I'd like to start by framing the key assumptions that underpin our guidance so that you can see what's driving the outlook, particularly around margin expansion and certain inputs for our market-driven businesses. Our guidance rests on a simple premise. We plan to operate more efficiently while continuing to reinvest to drive organic growth. On investment priorities, we're focused on a few clear themes. First is product innovation and continuing to enhance our benchmarks proprietary data and workflow tools to support organic growth. Second is investment in strategic growth areas like private markets and energy expansion where we see durable long-term demand and opportunities to leverage synergies across multiple divisions. Third is our investment in AI for both our products and for our internal productivity. And finally, we're extending our geographic reach and client segment coverage so that we can bring our strongest offerings to more customers and capture new opportunities over time. On productivity initiatives, we're driving efficiencies through several work streams, including enhancements and data operations, software engineering and research. We'll also continue scaling internal GenAI initiatives, which are improving throughput and speed in a meaningful way. And we're pairing these tools with end-to-end process reengineering, so the productivity gains are sustainable, long-term value generators that scale, not just isolated use cases. Turning to our market assumptions. In Ratings, our outlook assumes Billed Issuance will be up low to mid-single digits in 2026, reflecting what we can see today in the maturity wall and underlying market conditions while recognizing that M&A, infrastructure and other opportunistic issuance remains unpredictable. In Indices, we assume market appreciation of 5% to 7% from January 1 to December 31, consistent of the assumptions underpinning the medium-term targets from our Investor Day. Our exchange-traded derivatives business remains an important driver for indices and our guidance assumes low single-digit growth in ETD volumes. In Market Intelligence, we expect continued momentum and healthy growth from our subscription-based offerings. We are taking a prudent approach to 2026 guidance for Market Intelligence reflecting the unpredictability of some of our volume-driven products. Our guidance today assumes fairly modest growth in one-time sales as well as those volume-driven products. Our outlook for energy reflects the market environment and sanctions as discussed previously. This sanctions assumption remains unchanged based on the current environment and the expectation that the duration and scope of the sanctions will not materially change. This leads us to our guidance for the enterprise on Slide 25. On an organic constant currency basis, we expect revenue growth of 6% to 8%. On a reported basis, growth is expected to be approximately 60 basis points higher, reflecting the impact from acquisitions, divestitures and currency movements. Excluding the contributions from OSTTRA in 2025, we expect to expand margins in 2026 by 50 to 75 basis points. Including the impact of OSTTRA, we would expect adjusted operating margins to expand by 10 to 35 basis points. Finally, adjusted diluted EPS is expected to be in the range of $19.40 to $19.65, representing growth of 9% to 10% year-over-year driven by operating income growth and share count reduction, partially offset by a higher tax rate. We're not providing 2026 GAAP guidance at this time other than for reported revenue and capital expenditures. Because the timing of the Mobility spin remains uncertain, we cannot reliably predict all the GAAP components. Upon completion of the spin, our plan is to initiate GAAP guidance for 2026. Let us now turn to our division revenue outlook for 2026 on Slide 26. For Market Intelligence, we expect to sustain solid organic constant currency growth in 2026 in the range of 5.5% to 7%, supported by continued strength in subscription revenue which we would expect to grow closer to the top half of the range, partially offset by the assumption of slower growth and onetime sales and volume-driven products. In Ratings, we expect to see organic constant currency growth in the range of 4% to 7% in 2026. That outlook assumes Billed Issuance growth in the low to mid-single-digit range, as highlighted earlier. Our guidance assumes transaction revenue and nontransaction revenue grow at similar rates in 2026. While we expect strong refinancing activity, M&A activity is inherently difficult to predict as is the potential spend on technology infrastructure. We have also seen softness in bank loan volumes in January and we are reflecting modest expectations for those volumes in our guidance as a result. As always, we expect to refine our issuance forecast as we progress through the year. For energy, we expect organic constant currency revenue growth of 5.5% to 7% in 2026. We'll continue to manage through known headwinds, including sanctions-related impacts and the work we're doing to stabilize and reposition parts of the Upstream portfolio. Our guidance assumes approximately 60 basis points of headwind from the customer sanctions I discussed previously. For Mobility, we expect organic constant currency growth of 7.5% to 9%, reflecting continued strength in the subscription base and the mission-critical nature of the products. We remain confident in the long-term growth for manufacturing, our guidance for 2026 assumes only modest growth until we see more concrete signs of acceleration. And for Indices, we expect organic constant currency revenue growth of 10% to 12%. After two consecutive years of strong equity market performance, we're assuming a more normalized equity backdrop. Our exchange-traded derivatives remain an important contributor, particularly in volatile periods, and we continue to invest in innovation across new products, asset classes and distribution channels to support growth. With that, let me turn the call back over to Mark for your questions.
