Thanks, Ari. And good morning everyone. Let's start with revenue. Fourth quarter revenue of $3,958 million grew 2.3% on a reported basis and 3% constant currency. In the quarter COVID-related revenues were approximately $10 million, which is down about $50 million versus the fourth quarter of 2023. Excluding all COVID related work both from this year and from last, constant currency growth was about 4.5%. And as Ari mentioned, acquisitions contributed approximately two points of this growth. Technology & Analytics Solutions revenue for the fourth quarter was $1,658 million which was up 8.3% reported and 9.5% constant currency. R&D Solutions fourth quarter revenue of $2,123 million was down 1.3% reported and 1% constant currency. But excluding all COVID-related work, R&DS revenue grew over 1% at constant currency. And finally, Contract Sales & Medical Solutions’ fourth quarter revenue of $177 million declined 4.8% reported and 3.2% of constant currency. Now for the full year, revenue was $15,405 million, that's up 2.8% reported and 3.4% at constant currencies. COVID-related revenue totaled approximately $110 million for the year. Excluding all COVID-related work from this year and last, constant currency growth and revenue was 5.5% for the year. Full year Technology & Analytics Solutions revenue $6,160 million, that was up 5.1% reported, 5.7% at constant currency and 6.5% excluding all COVID-related work at constant currency. Full year revenue in R&D Solutions was $8,527 million, up 1.6% on a reported basis, 2% of constant currency. Excluding all COVID-related work growth in constant currency in R&DS was over 5%. And finally our full year CSMS revenue was $718 million, down 1.2% reported but up 1.4% at constant currency. As Ari mentioned in his opening remarks, the 2024 growth trajectory in TAS played out as we anticipated with improvements every quarter. We had we experienced a softening growth rate throughout 2023 due to cautious customer discretionary spending and we predicted that 2024 would be a turnaround year based on our forward-looking indicators in recent history. In fact, that's what happened in 2024 TAS growth picked up significantly, finishing the second half with high single digit growth driven by strong mid-single digit organic growth. As you know, TAS is a short cycle part of our business and as we've seen, 2023 gave us early insight into customer spend behavior during the downturn. By the same token, we expect that the 2024 turnaround in TAS serves as a good leading indicator of the industry's recovery for 2025. Let's move down the P&L. Adjusted EBITDA in the quarter was $996 million, representing growth of 3.1% full year. Adjusted EBITDA was $3,684,000,000, that's up 3.2% year-over-year. Fourth quarter GAAP net income was $437 million and GAAP diluted earnings per share was $2.42. For the full year GAAP net income was $1,373,000,000 or $7.49 of earnings per diluted share. Adjusted net income was $564 million for the fourth quarter and adjusted diluted earnings per share was $3.12. That for the full year brought adjusted net income to $2,042,000,000 in adjusted diluted earnings per share to $11.13. R&DS backlog at December 31 was $31.1 billion, an increase of 4.4% year-over-year and 5.5% at constant currency. And to anticipate the question that, I think, we'll get about why backlog was flat sequentially versus Q3, recall that the dollar strengthened considerably during the fourth quarter and we have to retranslate the backlog at the end of each quarter for reporting to you and that knocked about a $0.5 billion off the backlog that retranslation alone. As of December 31, cash and cash equivalents totaled $1,702,000,000 and gross debt was $13,983,000,000, resulting in net debt of $12,281,000,000. Our net leverage ratio ended the year at 3.33 times trailing 12-month adjusted EBITDA. Fourth quarter cash flow from operations was $885 million. And CapEx was $164 million resulting in free cash flow of $721 million for the quarter, a record quarterly free cash flow. For the full year free cash flow was $2,114,000,000, as Ari said, up 41% year-over-year. Now you note that in the quarter we repurchased $1,150,000,000 of our shares bringing our full year share to $1,350,000,000. And just yesterday actually the IQVIA Board of Directors replenished the share repurchase authorization by $2 billion, which increases the total remaining authorization to approximately $3 billion. Now let's turn to the guidance. For the full year, we're reaffirming our 2025 outlook, which is for revenue growth at constant currency ex-COVID of 4% to 7%, adjusted EBITDA margin expansion of up to 20 basis points, and adjusted diluted earnings per share growth of 5% to 9%. This translates into total revenue between $15,725 million and $16,125 million, which includes just over a $100 million step down in COVID-related work, which is entirely in R&DS and of which 75% will be in the first half and 25% the second half. We expect 100 basis points to 150 basis points of contribution from M&A activity and an FX headwind should rates continue of approximately 150 basis points versus 2024. Our adjusted EBITDA guidance is $3,765 million to $3,885 million in adjusted diluted EPS guidance is $11.70 to $12.10. This includes about $675 million of net interest expense, approximately $575 million of operational D&A, an effective income tax rate of about 18.5%, and an average diluted share count of approximately 178 million shares. The guidance also assumes $2 billion of cash deployment split between acquisitions and share repurchase. And finally, the guidance assumes that foreign currency rates as of February 5 continue for the balance of the year. Now at the segment level, guidance is also unchanged for TAS, R&DS and CSMS. No changes in any of the segments. We expect TAS revenue to grow 5% to 7% at constant currency, which translates into $6.3 billion to $6.5 billion. A note, we'll have easier comps in the first half than the second half. R&DS revenue is expected to grow 4% to 6% at constant currency ex-COVID, which translates into $8.7 billion to $8.9 billion of revenue. This guidance includes over $100 million of step down in COVID-related revenue that represents about 100 basis points of headwind R&DS growth rate. We anticipate that R&DS growth rates will be lower in the first half and improve sequentially thereafter. A final CSMS revenue is expected to be approximately $700 million flattish year-over-year. Now let's look at first quarter guidance. For the first quarter we expect revenue to be between $3,740 million and $3,790 million. Note that Q1 has the largest impact in the year for both foreign exchange and COVID revenue step down for a total of approximately 300 basis points of headwind. Adjusted EBITDA is expected to be between $870 million and $890 million in the quarter, and adjusted diluted EPS is expected to be between $2.60 and $2.70. And as mentioned, our guidance assumes that foreign currency rates of February 5 continue for the balance of the year. So, let's summarize. We delivered an excellent fourth quarter, which closed out a strong year. For the full year, revenue grew 5.5% of constant currency excluding COVID-related work. Adjusted EBITDA margin continued to expand and adjusted diluted EPS was up 9.1%. Free cash flow was a record in the quarter at $721 million, bringing the full year to over $2.1 billion, up 41%. In the quarter, we repurchased $1,150 million of her shares for the full year. Share repurchase was $1,350 million. Our Board of Directors increased our share repurchase authorization by $2 billion, which brings the remaining authorization to approximately $3 billion. During the year, we introduced 60 innovations including 39 AI-enabled applications, and the momentum continues to build with our recently announced collaboration with NVIDIA. IQVIA was named a Fortune's list of World's Most Admired Companies for the eighth consecutive year and earned first place ranking in our industry group for the fourth consecutive year. And lastly, we reaffirmed our full year 2025 revenue growth guidance at constant currency of 4% to 7%, adjusted EBITDA margin expansion of up to 20 basis points and adjusted diluted earnings per share growth of 5% to 9%. And that concludes our formal remarks. Let me hand it back over to the operator to open up the call Q&A.
