Good afternoon. As Ari highlighted, 2025 is off to a great start. We have delivered strong operating financial performance at UFC and WWE and have raised our expectations for performance for the remainder of the year. I'll provide more detail on the outlook later in my remarks. Before I review our financial statements, I'll briefly touch upon the basis of presentation. As we mentioned on our last earnings call, the acquisition of IMG, On Location, and PBR is accounted for as a merger between entities under common control. As a result, our first quarter results include three months of activity, even though the acquisition closed on February 28, and we only owned and controlled these businesses for one month. In addition, our first quarter 2024 results have been recast to include activity for these businesses. The financial results for the periods that we did not own the acquired businesses were prepared by Endeavor and include allocations of expenses to the businesses based on Endeavor's overall corporate expense profile. This presentation is consistent with the carve-out financial statements for the acquired businesses included in our information statement on Form 14C filed in connection with the transaction. These expenses consisted of certain support functions that were provided on a centralized basis, such as finance, human resources, information technology, facilities, and legal, among others. Endeavor allocated these corporate expenses on a pro-rata basis of headcount and gross profit. In total, such corporate allocations in Q1 were $21.7 million and represent the amounts solely from January 1 to February 28, the two months that we did not own the businesses. The corporate allocations were $30.7 million for the three months ended March 31, 2024, reflecting a full three months of Endeavor ownership a year ago. To be clear, under TKO Group Holdings, Inc. ownership effective February 28 of this year, such corporate allocations will no longer occur. With respect to segment reporting, in connection with the acquisition, we performed a review to determine the optimal reporting structure for the company. Based on this review, we've added a third reporting segment, IMG, which consists of the operations of the IMG business and On Location. To that end, we included PBR within our corporate group and have renamed it Corporate and Other. With respect to UFC and WWE, both will remain standalone reporting segments, and there is no change in how we are presenting these businesses in our financial statements. UFC and WWE remain core drivers of TKO Group Holdings, Inc., and we will provide the exact same presentation and disclosure as we have since the inception of the company. In connection with our review of segmentation, we've also reviewed our various revenue verticals, as well as key performance indicators, and have updated our disclosure. With respect to revenue verticals, we've made some small tweaks to the nomenclature. Most notably, we've revised sponsorship revenue to partnerships and marketing revenue, which better reflects the strategic and operational functions of this area of our business. With respect to the select KPIs to be disclosed in our 10-Q, we've added KPIs for the acquired businesses that provide additional transparency for several important metrics, such as the number of events, clients, and hospitality packages sold. When we announced the acquisition, we represented that we would work hard to assist the investment community in better understanding the drivers of the financial results for these businesses. We plan to periodically reference these metrics in future discussions as warranted. Before I get into more detail on our financial results, I wanted to comment on the macroeconomic environment. As we know, this is a topic on investors' minds. We're paying close attention to consumer behavior, but to date, we're not seeing any signs of a slowdown across our portfolio, including our premium hospitality business On Location. As I'll discuss in more detail in a moment, we continue to see significant strength, particularly with respect to live events and partnerships. As for tariffs, we are largely insulated as the vast majority of our revenue is not expected to be directly impacted. One area of our business with a limited impact is consumer products. However, since WWE and UFC rely heavily on a license model and have minimal self-manufactured goods, the impact is not expected to be in any way significant. Now turning to our consolidated financial results for the first quarter, inclusive of the acquired businesses. We generated revenue of $1.269 billion, an increase of 4%. Adjusted EBITDA was $417 million, an increase of 23%. Our adjusted EBITDA margin was 33%, an increase from 28% in the prior year period. Our UFC segment generated revenue of $360 million, an increase of 15%. Adjusted EBITDA was $227 million, an increase of 17%. UFC's adjusted EBITDA margin was 63%, an increase from 62% in the prior year period. UFC had 11 total events, including three numbered events, in both the first quarter of this year and last year. As we previewed on our last call, the mix shifted to a higher proportion of events with live audiences, with seven in the first quarter compared to five last year, including two additional international events. Live events and hospitality revenue increased 66% to $59 million. The increase reflected higher site fee revenue, primarily related to the Fight Night held in Saudi Arabia, as well as an increase in ticket sales, which reflected the two additional events with live audiences, as well as strong underlying trends in pricing and attendance. Partnerships and marketing revenue increased 32% to $64 million. The increase was driven by new partnerships as well as partnership renewals. We continue to make significant progress in growing this area of our business, as highlighted by our recent renewal with long-standing partner, Monster Energy. This agreement was the largest partnership deal in UFC history. We also signed a groundbreaking new nine-figure multiyear partnership agreement with Meta. Media rights production and content revenue increased 4% to $224 million. The increase was primarily driven by the contractual escalation of media rights fees. Adjusted EBITDA reflected the increase in revenue, partially offset by an increase in expenses. Direct operating expenses increased primarily due to higher production, marketing, athlete costs, and direct cost of revenue due to the mix of event venues and territories. SG&A increased primarily due to higher personnel costs and travel expenses compared to the prior year period. Our WWE segment generated revenue of $392 million, an increase of 24%. Adjusted EBITDA was $194 million, an increase of 38%. Adjusted EBITDA margin was 50%, up from 44% in the prior year period. Live events and hospitality revenue increased 52% to $76 million. As with UFC, we continue to see strong underlying trends for WWE live events. The increase was primarily related to an increase in ticket sales, which more than offset a decrease in site fees. That is purely time-related. As a reminder, we received a meaningful site fee for Elimination Chamber in Perth, Australia, in the first quarter of last year. Partnerships and marketing revenue increased 86% to $26 million due to new partnerships and renewals across multiple categories, including financial services, telecom, beer, wine, spirits, and QSR, among others. While it occurred in April, WrestleMania 41 was emblematic of the momentum we're seeing in this area. The event, which featured a record 28 total partners, including a partner sponsor for each of the 14 matches over the two nights, set an all-time record for partnership's revenue, more than double the previous record from last year's event, as well as records for ticket sales, premium hospitality, and consumer products. Media rights production and content revenue increased 14% to $252 million. As expected, results reflected the expansion of SmackDown to a three-hour format for the first half of the year, resulting in a shift in quarterly revenue recognition but has no impact on the full-year amounts. The increase was also driven by the contractual escalation of media rights fees, including the January commencement of our long-term agreement with Netflix to distribute Raw in the US and all of WWE's content internationally. Adjusted EBITDA reflected the increase in revenue, partially offset by an increase in expenses. Direct operating expenses increased primarily due to higher talent costs. SG&A increased due to higher travel expenses, primarily related to the mix of venues and territories, including a three-week eleven-city tour across Europe leading up to WrestleMania. Our IMG segment generated revenue of $476 million in the quarter, a decrease of 13%. Adjusted EBITDA was $74 million, a decrease of 10%. Adjusted EBITDA margin was 15% in both periods. The decline in revenue primarily related to On Location for the Super Bowl and Collegiate Bowl games. The venue location, New Orleans, compared to Las Vegas for the Super Bowl, and the matchups, notably the third straight Super Bowl appearance for the Kansas City Chiefs, as well as a quarter-final Rose Bowl in 2025 compared to a semifinal game in 2024, impacted the year-over-year performance. Adjusted EBITDA primarily reflected the decrease in revenue, partially offset by a decrease in expenses. The decrease in expenses primarily reflected the absence of media rights costs for the FA Cup, which was no longer part of the IMG business in Q1 2025. Corporate and other revenue was $54 million, an increase of $2 million. The activity related to PBR and reflected growth in live events and partnerships, partially offset by a decrease in media rights related to the early termination of the Meritree Media content distribution deal. Corporate and other adjusted EBITDA was a negative $77 million, essentially flat with the prior year period. This amount includes the $22 million of costs related to corporate allocations of Endeavor corporate expenses for the two-month period prior to the close of the acquisition. For the avoidance of doubt, from February 28 forward, there'll be no additional corporate allocation expenses of this nature. Also in connection with the acquisition, we've evaluated the treatment of various costs at these businesses and made certain adjustments to conform the presentation to the methodology used for UFC and WWE. In aggregate, this resulted in a reclassification of approximately $10 million of costs in the quarter from the IMG segment to Corporate and Other. Now moving on to our capital structure. In the first three months of the year, we generated $136 million of free cash flow. Our free cash flow conversion of adjusted EBITDA was 32%. Free cash flow included $27 million of capital expenditures. As we discussed on our February earnings call, we expect 2025 free cash flow to include the impact of approximately $300 million of nonrecurring payments related to the recent UFC antitrust settlement and M&A. In Q1, we realized $175 million of these payments, the second $125 million installment payment under the settlement agreement, as well as transaction costs. As such, our free cash flow was adversely impacted. Free cash flow for the quarter was positively impacted by $100 million of prepayments related to On Location and the 2026 FIFA World Cup. These amounts are included in cash flows from operations and, therefore, are a part of our cash flow calculation. We expect the World Cup prepayments to be a substantial source of cash over the course of 2025, followed by a substantial use of cash in 2026 as payments are due nearer to the tournament taking place. As we did this quarter, we intend to separately identify this item going forward so investors can follow the underlying cash flow generation of our business. As previously disclosed, on March 31, we made our first quarterly cash dividend payment out of TKO OpCo of approximately $75 million. We ended the quarter with $2.776 billion in debt and $471 million in cash and cash equivalents, as well as $159 million of restricted cash. With respect to our previously announced $2 billion share repurchase program, we continue to expect the program to commence in the second or third quarter of this year, with our timing and level of activity ultimately subject to market conditions and related factors. In the meantime, we continue to accumulate cash and carefully evaluate our capital needs. We're monitoring market conditions closely and are mindful of recent volatility. I would like to underscore that in this environment, Ari, Mark, and the board believe we should remain prudent and conservative for the time being. That said, we remain committed to a robust and sustainable capital return program that balances return of capital to shareholders with organic investment, such as our entry into boxing, and maintaining our strong balance sheet. As per boxing, in early March, we announced that we entered into a multiyear partnership to establish a new boxing venture. We will serve as the managing partner, providing day-to-day operational management and oversight of the promotion. We've commenced operationalizing the JV and will provide updates as and when appropriate. Now turning to our outlook. As we've discussed in the past, we manage the business with a focus on full-year performance. Therefore, we believe results are best evaluated on a full-year basis given the quarterly fluctuations that are inherent in our operations. As noted in our press release, based on strong performance at UFC and WWE through the first three months of the year and our anticipated performance for the balance of the year, we are increasing our expectations for TKO Group Holdings, Inc., excluding the impact of the acquired businesses. We are now targeting revenue of $3.005 to $3.75 billion and adjusted EBITDA of $1.39 to $1.43 billion, an increase of $75 million and $40 million, respectively, as compared to the guidance we issued in February. The increase was driven by continued strength across each vertical of our businesses. We are also updating our guidance to include the acquired businesses and the associated transaction impacts. For full-year 2025, we are targeting revenue of $4.49 to $4.56 billion and adjusted EBITDA of $1.49 billion to $1.53 billion. When we announced the deal last October, we presented an expected full-year 2025 revenue and adjusted EBITDA contribution from these acquired businesses, inclusive of expected run-rate cost savings, of approximately $1.555 billion and $165 million, respectively. The amounts included in our guidance represent an expected full-year 2025 revenue and adjusted EBITDA contribution of approximately $1.45 billion and $100 million, respectively. The updated contribution is a result of the following: Number one, the previously mentioned $21.7 million corporate allocations from Endeavor for January and February. Given the fact that our carve-out financial statements were not yet prepared, the quantum was unknown at the time. The $21.7 million is a nonrecurring accounting adjustment and does not reflect the ongoing cost base of the acquired businesses. Number two, our prior cost savings and transaction impacts target of $30 million plus. We've been hard at work identifying and actioning upon these synergies. I'm pleased to report that we have identified $40 million plus of estimated run-rate cost savings, of which approximately $15 million are expected to be realized in 2025, with the vast majority expected by year-end 2026. The $15 million in-year 2025 contribution comps to the prior $30 million plus run rate. Number three, at PBR, the previously disclosed loss of our domestic media rights agreement with Merit Street Media. While we remain in active discussions with various parties, our 2025 outlook excludes any revenue or adjusted EBITDA related to a new rights agreement. With respect to the IMG and On Location businesses, the expected contribution is essentially consistent with the amounts we disclosed when we announced the transaction. In terms of free cash flow, as we discussed on our last call, while we have not given formal guidance, excluding the impact of approximately $300 million of nonrecurring amounts, our targeted full-year 2025 free cash flow conversion rate would be in excess of 60%. This is exclusive of the benefit of any restricted cash. Including the impact of the acquired businesses, our view remains unchanged. Consistent with our prior calls, while we are not providing quarterly guidance, we want to highlight a few notable items as we look to the second quarter. At UFC, results will reflect the mix of events in the quarter. UFC is currently scheduled to have 11 total events, including four numbered events, which is comparable to the second quarter of last year. We also expect one additional fight night with a live audience and one less Apex Event compared to the prior year. With respect to live events revenue, the Fight Night scheduled to take place in Baku, Azerbaijan, carries a meaningful site fee. But as a reminder, the second quarter of 2024 included a site fee related to UFC's first-ever event in Saudi Arabia. At WWE, given the timing of our event calendar, including WrestleMania as well as a premium live event in Saudi Arabia, we expect the second quarter to be the highest revenue and adjusted EBITDA quarter of the year in terms of absolute dollars. At the IMG segment, the first quarter of the year is historically the most profitable due to the timing of events, most notably the Super Bowl. As a result, we expect a quarter-over-quarter decline in adjusted EBITDA in terms of absolute dollars. In conclusion, we generated strong first-quarter results that reflect continued momentum across our businesses, in particular, UFC and WWE. While we still have a lot of work ahead of us, the integration of IMG, On Location, and PBR is well underway and yielding meaningful early benefits. We are extremely excited about the road ahead and our prospects for the remainder of the year and beyond. With that, I'll turn it back to Seth.
