Thank you, Chris, and hello, everyone. I'll begin with a look at our financial results for the fourth quarter and then discuss our business outlook for fiscal year 2024. I'm pleased to report that our revenue and profitability metrics not only met but exceeded our Q4 guidance. Free cash flow also remained strong, allowing for substantial debt reduction in the fourth quarter. Fourth quarter revenue was $2.23 billion, which included $574 million added by the Webhelp business for the last two months of the quarter. We will not be separately reporting Webhelp performance going forward as we are now managing the business on an integrated basis. On a pro forma basis, as if the Webhelp combination was completed at the beginning of the fourth quarter, revenue for the quarter was $2.42 billion, resulting in pro forma constant currency growth of approximately 3.5%. As anticipated, the contribution from the legacy business came in at the low end of our prior full year guide and the Webhelp business contributed faster growth. Revenue increases with clients in our four strategic verticals more than offset some volume softness with a few clients. On a pro forma basis, revenue from retail, travel and e-commerce clients grew 12% in the quarter. Pro forma revenue from banking, financial services and insurance clients grew 6%. Healthcare client revenue grew 5% on a pro forma basis. Revenue from technology and consumer electronics clients grew by 1% on a pro forma basis as growth with several clients was offset by continued softer volumes with a large consumer electronics client. Continuing trends from earlier in the year, pro forma revenue from communications and media clients decreased by 3% and revenue from clients in our other vertical decreased 6%. While we grew on a pro forma basis with 14 of our 20 largest clients, softer volumes with a handful of consumer electronics, retail, e-commerce and communications clients remained a headwind. Turning to profitability. Non-GAAP operating income was $341 million in the fourth quarter, up $93 million compared with last year. Our non-GAAP operating margin was 15.3%, up 20 basis points from the fourth quarter last year. Adjusted EBITDA was $398 million, up $113 million compared with last year. Our adjusted EBITDA margin was 17.8%, up 40 basis points from last year. This margin progress reflects profit flow-through on revenue growth efficiency gains across our operations and early attainment of synergies from the Webhelp combination. On a pro forma basis, as if the Webhelp transaction had closed at the beginning of the prior year's fourth quarter, profitability metrics would have been as follows: non-GAAP operating income of $365 million, up $22 million compared with last year. Non-GAAP operating margin of 15.1%, up 50 basis points from the prior year. Adjusted EBITDA of $429 million, up $28 million. And adjusted EBITDA margin of 17.8%, up 70 basis points from last year. The large swing in our reported other expense line in the quarter was mostly due to items associated with the Webhelp combination. These included a $16 million increase in the fair value of contingent share consideration related to the combination and $13 million in net foreign currency losses. We believe that these items do not reflect the underlying health of our operations and future changes in the fair value of contingent share consideration and foreign currency movements are not predictable. Accordingly, we have adjusted our non-GAAP net income and non-GAAP EPS metrics to exclude these items. Going forward, our reporting of non-GAAP net income and non-GAAP EPS exclude the change in fair value of contingent share consideration related to Webhelp combination and net foreign currency gains and losses. We believe that this change removes confusion in the reported non-GAAP net income and EPS results and more closely aligns our reporting with investors' expectations. This measure is also on a consistent basis with how we provided non-GAAP EPS guidance for the fourth quarter. The presentation for all prior periods has been updated to reflect this change. Non-GAAP net income was $213 million in the quarter compared with $146 million last year. Non-GAAP EPS was $3.36 per share compared with $2.80 per share last year. GAAP results for the fourth quarter of 2023 included $40 million in expenses related to the combination and integration, $97 million in amortization of intangibles, $24 million in share-based compensation expense, a $16 million change in the fair value of contingent share consideration, $13 million in net foreign currency losses and $3 million in imputed interest related to the seller's note issued in connection with the combination. Turning to cash flow. Cash generation from operations in the fourth quarter totaled $229 million and capital expenditures were $65 million. This resulted in free cash flow of $164 million, including $40 million of transaction and integration costs related to the combination. This is within our guidance range for the quarter, which excluded the transaction and integration costs. For the full year 2023, we achieved our expectation of more than $500 million in free cash flow, excluding transaction and integration costs associated with Webhelp. Moving forward, we expect capital expenditures to be approximately 2.5% of revenue. Our GAAP and non-GAAP tax rates were 10% and 21%, respectively in the fourth quarter. This was lower than expected due to onetime items that changed the geographic mix of our income, reducing our exposure to certain minimum taxes and allowing us to use more net operating loss carry for us than we anticipated. Our non-GAAP tax rate for the full year was 24%. Turning to the balance sheet. At the end of the fourth quarter, cash and cash equivalents were $295 million, and total debt was of $4.94 billion. Net debt was $4.65 billion at the end of the fourth quarter. The gross debt balance included $2.15 billion of senior unsecured notes $1.9 billion outstanding on our term loan, the $762 million seller's note and $129 million of borrowings under our AR securitization facility and as reported net of debt issuance costs and discounts. Our gross debt of $4.94 billion at the end of the year represents a reduction of nearly $300 million since the close of the combination as we use free cash flow and a reduction of cash on the balance sheet to pay down debt. By year-end, we had reduced net debt by approximately $150 million after the combination closed. We reduced net leverage, which stood at 3.2 times pro forma adjusted EBITDA at combination close to 3.0 times by year-end. We did this in addition to continuing an active program for capital return. Our strong free cash flow generation and adjusted EBITDA growth gives us a clear path to reduce leverage further and we're committed to our plan to reduce net leverage to close to 2 times adjusted EBITDA within two years of the close of the combination. Regarding our capital allocation priorities, our focus remains on organic growth, the continued integration of Webhelp, realizing planned synergies and repaying debt. Consistent with our commitment to investment-grade principles, we will prioritize paying down debt and reducing our net leverage while continuing our dividend and disciplined share repurchases. During the fourth quarter, we paid $21 million through our annual -- quarterly dividend, I should say, of $0.3025 per share. We also repurchased 286,000 shares of our stock for approximately $23 million at an average price of approximately $79 per share. For the full year, we paid $64 million in dividends and made $81 million in share repurchases. At year-end, the remaining authorization on our share repurchase plan was approximately $290 million. We've continued to repurchase shares in the first quarter of 2024 with repurchases totaling approximately $11 million quarter-to-date. At year-end, our liquidity remained strong at $1.71 billion, including our $1.04 billion line of credit, which is undrawn, cash on hand, and the additional capacity of $371 million on our AR securitization. Our strong balance sheet and cash flow generation provides significant flexibility for the future. Now I'll turn my attention to the business outlook for the first quarter and full year 2024. To help with year-over-year comparisons on a go-forward basis, we have published quarterly pro forma revenue figures to help model future year-over-year performance. These figures demonstrate how the combined business would have performed if the transaction had closed at the beginning of 2023. The pro forma data is available in our historical metrics file, which can be accessed on our Investor Relations website. For the first quarter, we expect revenue to be in the range of $2.36 billion to $2.406 billion based on current exchange rates. This reflects approximately 1% to 3% pro forma constant currency growth and approximately 1.1% exchange rate headwind. Pro forma revenue was $2.36 billion in the first quarter of 2023. In terms of profitability, in the first quarter, we expect non-GAAP operating income in the range of $315 million to $325 million. At the midpoint of our guidance, this equates to non-GAAP operating income margin of approximately 13.4%, an increase of 10 basis points over the prior year and 40 basis points on a pro forma basis. On a pro forma basis, non-GAAP operating income was $307 million in the first quarter of 2023. Our non-GAAP EPS expectations for the first quarter are in a range of $2.51 per share to $2.65 per share. The calculation of this metric is consistent with the approach that I described earlier. As is typical in our business, we expect first quarter free cash flow to be approximately breakeven and for free cash flow to ramp up meaningfully in the second quarter. We expect interest expense in the first quarter to be approximately $79 million, excluding $4 million of imputed interest on the seller's note. We expect an effective tax rate of approximately 26% to 27%. We expect a weighted average diluted share count of approximately 65.8 million shares. Consistent with prior periods, our non-GAAP diluted EPS calculation follows the two class method, allocating earnings between common stock and participating securities. For the first quarter, we estimate that about 4% of net income will be attributable to participating securities, and about 96% of total net income will be attributable to common shares. Moving to our outlook for the entire year, we expect 2024 revenue to be in the range of $9.51 billion to $9.70 billion for the full year. This reflects approximately 1% to 3% pro forma constant currency growth and our revenue expectations net of a 70 basis point exchange rate headwind. Pro forma revenue was $9.49 billion for the full year 2023. Our full year profitability expectations include non-GAAP operating income in a range of $1.39 billion to $1.45 billion. At the midpoint of the range, this equates to a non-GAAP operating margin of 14.8%, an increase of 60 basis points over the prior year and 90 basis points on a pro forma basis. Our guidance for the full year reflects our confidence in achieving our year one synergy target of $75 million. For context, our current achieved net synergy run rate is approximately $55 million on an annualized basis. Pro forma non-GAAP operating income was $1.32 billion for the full year 2023. Our non-GAAP EPS expectations for the full year are in the range of $11.69 per share to $12.50 per share. We expect full year interest expense to be approximately $295 million, excluding $16 million of imputed interest on the seller's note. An effective tax rate of approximately 26% to 27% and a weighted average diluted share count of approximately 65.6 million shares. In calculating non-GAAP diluted EPS attributable to common shares for the full year, we expect approximately 96% of total net income will be attributable to common shares. In terms of cash flow, we expect another strong year with free cash flow growing by approximately 40% to over $700 million in 2024, inclusive of acquisition and integration costs. This has positioned us to further reduce our net leverage to approximately 2.5 times adjusted EBITDA by year-end, assuming no further acquisitions. We remain committed to reducing our net leverage to close to 2 times adjusted EBITDA within two years after the close of the combination. Our business outlook does not include any future acquisitions or impacts from future foreign currency fluctuations. In closing, we had a very successful year with strong revenue growth, margin expansion and free cash flow generation. We're excited about the combination with Webhelp, which has joined two leading CX providers into global platform for growth and value creation. We believe our range and global reach of high-value services and digital capabilities creates a unique customer engagement offering that will keep our business resilient through business cycles. We look forward to another year of growth and value creation. With that, operator, please open the line for questions.
