Thanks, John. Let's begin with our revenue growth on Slide three. Organic revenue growth in the quarter was 2.6%. Additionally, the impact on revenue from foreign currency translation increased reported revenue by 1.4% as the U.S. Dollar weakened relative to most currencies throughout the quarter. If rates stay where they are, we estimate the impact of foreign currency translation on revenue in Q4 to be similar to Q3. The net impact of acquisitions and dispositions on revenue was not significant, which is also our expectation for Q4 and for the full year 2025, excluding the IPG transaction. Let's now review our results in more detail, beginning with a summary of our income statement on slide four. We present our reported results on the left and we present non-GAAP adjusted numbers on the right. Adjusting for acquisition-related expenses and repositioning costs, our Q3 2025 non-GAAP adjusted EBITDA grew 4.6% to $651 million with a margin of 16.1%, up 10 basis points from 2024. Our non-GAAP adjusted diluted EPS grew 10.3% to $2.24 per share. Regarding the two adjustments made to operating expenses, the first reflects acquisition-related expenses, related to both regulatory approval work and acceleration in our integration planning work. The second reflects repositioning costs primarily related to severance, as we prepare to integrate the pending acquisition of IPG. There were no adjustments to operating expenses in 2024. Slide five shows reconciliation of these items in detail. Operating expenses in 2025 include $38.6 million of repositioning costs, and $60.8 million of acquisition-related costs. We continue to expect that our non-GAAP adjusted EBITDA margin for the full year 2025 will be 10 basis points higher than our full year 2024 results of 15.5%. Net interest expense in 2025 increased due to a decline in interest income primarily from lower interest rates on our cash investment balances, partially offset by a year-over-year decline in gross interest expense due to the issuance of $600 million of our 5.3% notes to replace the $750 million of our 3.65% notes which were retired in 2024. We estimate that net interest expense will increase by approximately $7 million in Q4 compared to the same quarter last year, primarily due to lower interest income expected on cash investments. Our reported income tax rate was 27.2% in Q3 2025, compared to 26.8% the prior year. The increased rate is primarily due to the non-deductibility of certain acquisition-related costs in 2025. On an adjusted basis, our Q3 '25 rate was 26%. For full year 2025, we expect the rate on an adjusted basis to be between 26.5% and 27%. Average diluted shares outstanding were down 2% from 2024 due to net repurchase activity. Let's now turn to some key drivers of our performance, beginning on slide six with organic revenue growth by discipline. Media and advertising led our growth in the quarter with revenues up 9%, while creative continued to be impacted by lower levels of project work due to macroeconomic uncertainty. Media growth was strong across virtually all geographies. Precision Marketing growth was just under 1%. Solid growth in the U.S. was offset by declines in other markets, primarily in Europe. Public relations declined 8%. Approximately $25 million or 80% of the decline results from no US national election-related revenue in 2025 versus 2024, with the majority of the remaining reduction occurring in the UK. We do expect similar declines in Q4 resulting from the difficult prior year comp to '24, which included spend related to the US national elections. Health care was down $6.4 million or 2% organically. Both our US and European agencies were down 2% organically as recent new business wins did not fully replace some spending declines in the quarter on client products that are in the process of coming off patent protection. We continue to believe that our agencies in this area are well-positioned to return to growth in the near future. Branding and retail commerce was again down 17%, as market conditions continued to impact new rebranding projects, new brand launches, and in-store retail commerce. Experiential declined 18% on a difficult comp against the Summer Olympics in 2024, as we expected. And lastly, execution and support grew 2% driven by growth in our merchandising business, which was partially offset by a reduction in spend in field marketing. Turning to organic revenue growth by geography on slide seven, we saw mixed growth across our regions. Over half of our revenue is generated in the United States, which saw 4.6% growth. UK growth was also solid at 3.7%, while Continental Europe, our second largest market, saw a decline of 3.1%. Although our non-euro markets delivered organic growth, it was offset by a decline in our events business related to the challenging comparison in 2024, which as we have said included spend related to the Paris Olympics. Slide eight is our revenue weighted by industry sector. Relative to 2024, year-to-date 2025 was fairly stable. The only meaningful change was an increase in the relative percentage of total revenue driven by the auto category, reflecting year-on-year new business wins. Other categories were relatively stable. Moving on to expense detail on slide nine, during the quarter, salary and related service costs, our largest expense, declined on a reported basis by 3.7% due to our continued efficiency initiatives, including automation initiatives and changes in our global employee mix. Third-party service costs grew in connection with growth in revenue, primarily in the media and advertising execution and support disciplines. Third-party incidental costs, which are out-of-pocket costs billed back to clients at our cost, grew in connection with the growth in revenue. Occupancy and other costs decreased 1%, led by a decrease in general office and technology expenses. SG&A expenses increased primarily due to the $61 million of IPG acquisition-related costs in the quarter. Excluding these costs, reported SG&A expenses decreased 2.5% of revenue. Now please turn to slide 10 for our year-to-date free cash flow summary. The decline relative to last year was driven primarily by the reduction in net income, resulting from the impact of both the acquisition-related costs and the repositioning costs. Our free cash flow definition excludes changes in operating capital. For the nine months ended 09/30/2025, our change in operating capital improved $171 million or 11% compared to the same prior year period. On a last twelve-month basis, it improved by $267 million. The nine months ended September 30, our primary uses of free cash flow included $414 million of cash to pay for dividends to common shareholders and another $57 million for dividends to non-controlling interest shareholders. Our capital expenditures were $111 million and remained higher than last year due to ongoing investment in our strategic technology platform initiatives. Total acquisition payments were $88 million, all of which represented earn-out payments and the acquisition of additional non-controlling interests. Finally, our share repurchase activity was $312 million, excluding proceeds from stock plans of $18 million. This included share repurchases of $89 million in Q3. We currently continue to expect to spend close to $600 million on share repurchases for the full year. Slide 11 is a summary of our credit, liquidity, and debt maturities. At the end of Q3 2025, the book value of our outstanding debt was $6.3 billion, down from the same prior year period due primarily to the refinancing of our $750 million of 3.65% notes in 2024 with a new issuance in 2024 of $600 million 5.3% notes due in 2034. Our $1.4 billion April 2026 notes are now classified as current on our balance sheet. We will address refinancing these notes in due course after the closing of IPG and the completion of the debt exchange. Cash equivalents and short-term investments at the end of the quarter were $3.4 billion. We continue to maintain an undrawn $2.5 billion revolving credit facility, which backstops our $2 billion US commercial paper program. Slide 14 presents our historical returns on two important performance metrics. The twelve months ended 09/30/2025. Omnicom Group Inc.'s return on invested capital was 17%, and return on equity was 31%. Both of which reflect our strong performance and our strong balance sheet. These year-over-year calculations were done on a reported basis and the reduction is driven by the impact of the IPG acquisition-related costs and the repositioning costs incurred in the twelve months ended 09/30/2025. It is approaching one year since our public announcement of the IPG acquisition, but as you know, we've been working on planning for the integration for some time. With closing expected by the end of next month, our teams have been accelerating the final planning for the integration so that we're prepared to move forward as one on day one. We're excited to be nearing this important milestone so we can emerge as the most powerful team, platform, and portfolio in the industry. I'll now ask the operator to please open the lines up for questions and answers. Thank you.
