Thank you, Ben, and thank you to everyone joining us for our fourth quarter and full-year earnings call. With 2023 behind us, we're ready to return in 2024, a political year to the organic growth that Stagwell showed year after year since its inception, while we strongly execute our strategy to transform marketing through the right combination of technology and talent. 2023 saw a combination of unique factors weigh on the marketing services industry. Persistent worries about a potential recession, rising interest rates, and geopolitical risk resulted in significant restructuring actions, particularly at tech companies as well as meaningful cuts across marketing budgets, add to that a banking crisis and strikes within autos and entertainment industries. Despite all this, Stagwell grew market share with some of our largest customers, continued to win significant new business, and delivered another year of strong adjusted EBITDA generation by taking prudent cost management steps. We also made significant moves with a lasting positive impact on our business. In the first quarter, we successfully completed a secondary offering, which helped to boost our liquidity. The equity research analyst community has taken note of increased interest in Stagwell after this offering, and we now have eight covering analysts. In the second quarter, we moved to simplify our capital structure and removed an overhang by buying out AlpInvest. This transaction and other buybacks completed throughout the year successfully reduced our share count by 12%. In the fourth quarter, we completed the sale of ConcentricLife to Accenture for $245 million, representing a sale at 18 times EBITDA and approximately 4 to 5 times our initial investment. This sale of a company that I had never been asked about by investors or analysts is representative of the Company's underlying value and produced a taxable gain of about $175 million this year. We've already replaced the revenue and EBITDA given up by the transaction, while only using a fraction of the proceeds. We believe that modest portfolio turnover at multiples higher than those we pay for acquisitions is a vital part of our operations moving forward. As I previously mentioned, we expect to close another profitable disposition later this year. We also moved to strengthen our services, grow our geographic footprint, and invest in innovation to keep us at the forefront of digital marketing. We acquired leaders in digital technology and emerging platforms, Left Field Labs and Movers and Shakers. We made our first acquisition in Ireland in the company of Huskies. Recently, we welcomed the digital-first creative collective Sidekick, and our first French creative agency, What's Next Partners. We grew the Stagwell Marketing Cloud's capabilities and commercialization path through unique partnerships with tech leaders. We created a partnership with Google to co-build Gen AI solutions and get placement out of our AI-enabled products in their cloud store. And we created a partnership with MNTN, the leader in performance TV to give access to our SMC influencer and content products to MNTN clients as well as help clients in our Media business with performance marketing strategy. On the third quarter call, I said we were seeing positive signs of a turnaround in our business and expected a recovery over the next two quarters. We saw this unfold partially in the fourth quarter as we returned to sequential net revenue growth. In the quarter, Stagwell posted $655 million of revenue and $551 million of net revenue as we started to see the challenges that have impacted our business abate. For the full year, revenue was $2.53 billion and net revenue was $2.15 billion. Our Performance Media and Data capability continued to post good results in the fourth quarter, growing net revenue by 1% and 5% for the year. Strong performance among our media and buying and strategy brands is leading the group. Those brands posted 7% year-over-year growth in the fourth quarter, their best quarterly growth figure in the last two years. This strength is offset somewhat by macro-driven challenges in some of our owned media businesses. Importantly, our digital transformation businesses showed meaningful signs of a rebound. Excluding advocacy, digital transformation declined 3% year-over-year in the fourth quarter, a significant improvement sequentially after posting a 17% decline ex-advocacy in the third quarter. We once again grew the size of our relationships with our biggest and most important customers, something we did consistently through 2023. In Q4, our top 100 customers, representing approximately 48% of net revenue, grew 13% year-over-year. Our international businesses also continued their momentum with growth of 3% in the quarter, led by 19% growth in the UK. We posted a very strong quarter of net new business wins over $65 million. For the last 12 months, we have delivered more than $270 million of net new business at an all-time LTM high. In the fourth quarter, we continued to focus on effectively managing our cost structure so that we're well-positioned for 2024. On staffing, we took actions in the fourth quarter that resulted in an incremental annualized savings of $16 million. For the full year, we took $98 million of actions, we are seeing the results of the new business gain and cost reductions in a strong January. We also continued our efforts to consolidate our real estate footprint and back office functions, resulting in $4 million of real estate savings and more than $4 million of savings through our Shared Services program. I'm delighted to report that as of the end of 2023, we've principally achieved ahead of schedule the $30 million of synergies that we promised. We are now focused on achieving the $35 million of incremental efficiencies that we announced earlier this year. As a result, we produced another strong quarter of profitability, delivering $95 million of adjusted EBITDA, representing a 17% margin. We did this even while continuing to meaningfully invest in the Stagwell Marketing Cloud. For the full year, we delivered $360 million of adjusted EBITDA, representing a 17% margin. We invested approximately $20 million out of operating funds on development of new technology, an investment I consider proportionate and critical to our future. Our approach to the use of capital remains the same. This year we invested in growth through buybacks, acquisitions, and internal tech development. And we did see expanded media working capital requirements that we're working to reduce. Overall deferred acquisition costs are a fraction of the past and were reduced by $60 million this year and are projected to be only about $40 million in total by 2025. We believe leverage will be close to two by the end of the year, but our principal goal is seen through the vision of the company and achieving above-average industry growth. This year, we expect to deliver organic net revenue growth of 5% to 7%. We expect adjusted EBITDA to grow 11% to 25% year-over-year, delivering adjusted EBITDA of $400 million to $450 million. We also expect to convert approximately 50% of our EBITDA free cash flow this year. It's important to realize that Stagwell started at zero, just eight years ago, and the same energy we put in then is at work today in molding this company to be the next great company in marketing, going from global full-service to platform self-service. That means we have at play critical strategic initiatives to generate above-industry average growth to widen our margin. First and foremost is to grow our market share -- to grow our share of market by expanding our global and technology footprints. This has been evident in our new acquisitions and the steady stream of awards, our agencies whose creative work with the Super Bowl far exceeds our relative size, with five national in-game spots and more than a dozen other client campaigns for the NFL, ETrade, Paramount, United Airlines, Diageo, Budweiser and more. As a result, Stagwell's agencies have been invited to more RFPs with bigger accounts. Inspiration days with Fortune 100 companies that ask, what else can Stagwell do are becoming nearly a weekly event. Last year we saw a 20% increase in pitches that we were invited to, totaling almost $1.2 billion. We expect to see similar growth in 2024. Our record-breaking new business wins lay a strong foundation for us to return to growth this year. In the fourth quarter, our digital transformation revenue from technology customers grew by 30%. This resulted from a combination of increased spend from existing customers and the acquisition of Left Field Labs. TMT client are calling our agencies to transform their operations and customer touch points. Stagwell is helping Qualcomm for example to enable the future of AI for developers and across everyday devices, while next month RealClearPolitics will roll out a new AI overlay to their historical polling database that will help user search results in new and engaging ways. As we continue to receive new mandates with major wins at Samsung and Shopify, as well as notable account expansions with Amazon and Google. Our international expansion efforts are paying off as we saw 13% international growth in 2023. We'll continue to diversify the Company's geographic footprint, which is critical to expanding our global client remit. We expect to enter 10 new markets in 2024, bringing our non-affiliate footprint to 44 countries. In EMEA net revenue grew 70% last year and this year we are expanding further, launching the European headquarters in London at the Blue Fin Building and appointing James Townsend as our first EMEA CEO. Our advocacy businesses in 2023, a non-election year shrunk 22%, but posted 16% growth versus 2021, the last off-cycle year. While the presidential election gets the most focus, we expect fiercely contested, multi-hundred million dollar down ballot races. We view this as an encouraging sign that political spend records are going to be shattered in 2024, with more than $12 billion at stake. Second, we are rolling out more products from the Stagwell Marketing Cloud team. The group grew 31% in 2023. Harris Quest, our AI-enabled research suite, signed its 150th enterprise customer in 2023. On Monday, we unveiled our new product Unlock Surveys, potentially the most significant research panel launched in nearly a decade. And as opening day approaches, we are excited to share that around our immersive platform for stadiums has just been incorporated into Major League Baseball's native ballpark app and approved for use by all Major League baseball teams and stadiums. This is a major milestone for this emerging technology from Stagwell. Third, we're embarking upon an aggressive AI data and media strategy. We are building solutions that help our agencies and clients transform with the three E's of AI, Enable them across operations, Efficiency in marketing, and Engagement with consumers. We have built private GPT environments for our agencies and clients to utilize advanced AI without putting their data into the public domain. We'll continue building on this approach, and we've already signed a large domestic office supply retailer into our platform. On the data side, we'll develop an identity solution, the Stagwell ID Graph, which encompasses information on hundreds of millions of people globally. Built to top our existing data lake, this solution will make consumer information available to fine-tune all our performance marketing campaigns across all our agencies. We expect to acquire or build the last mile of the media chain so that our offerings will go from planning, targeting, and audience creation down to placement and media supply. We will move more from fee-for-service pricing to performance pricing. This should result in margin expansion over time and guaranteed ROI for clients as our Media business continues to grow in client scale and size. Remember that more than 1 in 10 Stagwell employees are engineers and that we're well-positioned to apply AI to meet client needs as they remake their websites, apps, and customer interfaces to incorporate AI. We are also applying AI to our own processes with products like profit that write news releases, Harris Quest AI that analyzes focus groups and smart assets that help sort out content directed to where it's likely to be most effective. Fourth, we will continue to streamline operations, both the back office and in our offerings. We are significantly offshoring our finance and other services and applying AI to tasks like reading and inputting the hundreds of thousands of media bills we receive each year. In addition to launching our own survey research panel, we will also consolidate production of scaled content to a central operation, reducing outside production bills by an estimated $20 million to $30 million over the next 18 months. All the major agencies within our group are partnering on this and we expect it to be operational by mid-year. In conclusion, I want to reiterate our excitement and confidence in 2024. We believe we're set up for a return to profitable organic net revenue growth in 2024, in line with the guidance I outlined earlier. Thanks to a multitude of factors, the abatement of the headwinds that weighed on the industry in 2023, combined with outstanding new business trends, continued momentum in our Marketing Cloud Products, and what we expect to be a record-breaking political cycle, as well as our prudent steps to manage costs, strengthen our services and expand geographically. We expect to return to outperforming legacy competitors in 2024. Now, I'll hand things over to Frank Lanuto, our Chief Financial Officer, to walk you through some of our financial results in more detail.
