Thanks, Michael. Q1 finished with strong momentum. As Michael mentioned, revenue ex-TAC adjusted EBITDA, and adjusted EBITDA margin all exceeded our guidance for the quarter. Total revenue for Q1 was $130 million. Revenue ex-TAC was $116 million, up 8% from Q1 of 2022. CTV revenue ex-TAC was $46 million, up from $42 million, or 10% from last year. DV+ revenue ex-TAC was $70 billion, an increase of 7% compared to Q1 last year. Automotive, travel and food and beverage were our top growth verticals for the quarter. Consumer categories such as technology, retail and health and fitness made more modest improvements. Our revenue ex-TAC mix for Q1 was 40% CTV, 40% mobile and 20% desktop. From a geographic perspective, we saw good international growth that was roughly double the growth rate of the U.S. Total operating expenses, which includes cost of revenue for the first quarter increased to $231 million, compared to $158 million in the same period a year ago. With the increase primarily driven by $53 million of non-cash accelerated amortization, resulting from our platform consolidation. Adjusted EBITDA operating expense was $93 million and within our guidance range. This was an increase of less than 1% sequentially from Q4. We would typically see a bigger increase seasonally, but the impact was offset by our RIF actions The increase from $78 million in Q1 of last year resulted from increased platform and personnel expenses along with return to office travel and event related costs. Net loss was $99 million for the quarter compared to net loss for the first quarter of 2022 of $45 million, which includes the previously mentioned $53 million of accelerated amortization expense. Adjusted EBITDA was $23 million versus $29 million for the same period last year, and adjusted EBITDA margin was 20%. Now that we calculate our adjusted EBITDA margin as a percentage of revenue ex-TAC. GAAP loss for basic and diluted share was $0.73 for the first quarter of 2023 compared to a loss of $0.34 for the first quarter in 2022. Non-GAAP earnings per share in the first quarter of 2023 was $0.04, compared to $0.08 reported last year. The $53 million of accelerated amortization expense had a negative impact on GAAP loss per share of $0.39, and a negative impact on non-GAAP earnings per share of $0.09 in Q1. The reconciliations to non-GAAP income and non-GAAP earnings per share are included with our Q1 results press release. We expect to recognize additional accelerated amortization expense of $53 million in Q2, and $8 million in Q3 this year. There were 135 million weighted average basic and diluted shares outstanding for the first quarter of 2023. Fully diluted weighted average shares utilized for non-GAAP earnings per share were $144 million for the first quarter. Capital expenditures including both purchases of property and equipment and capitalized internal use software development costs were $10 million for the quarter. Operating cash flow which we define as adjusted EBITDA less CapEx was $40 million for the quarter. Our net interest expense for the quarter was $8 million. During the first quarter, we purchased and retired approximately $50 million in face value of our convertible notes using approximately $41 million in cash, resulting in a discount of approximately 19%. We have $34 million remaining under our current program for the repurchase of common shares and our convertible debt. Cash balance at the end of Q1 was $237 million. The reduction from year-end is based on use of cash for the repurchase of our convertible notes, typical seasonality and timing of receivable payments around quarter end. Our net leverage ratio was approximately 2.5x at the end of Q1, down from 3.1x year-over-year. We expect the ratio to be meaningfully below 2x at year-end. We are excited about our business and ability to generate strong cash flow, while providing the flexibility to reduce debt and maintain a healthy cash position. We continue to expect to generate significant free cash in 2023, especially in our seasonally strong second half. And we will continue to evaluate the best use of our cash as it relates to debt reduction and share repurchases. I will now share our expectations for the second quarter and thoughts for the year. Our guidance is based on recent growth trends. Although we have been somewhat measured, due to the continued uncertainty in the macro environment. For the second quarter, we expect revenue ex-TAC to be in the range of $132 million to $136 million. We expect revenue ex-TAC attributable to CTV to be in the range of $56 million to $58 million. We expect adjusted EBITDA operating expenses to increase slightly from Q1 to between $94 million and $96 million, which implies adjusted EBITDA margin of approximately 29% for Q2 at the midpoint. For 2023, we expect our revenue ex-TAC growth rate for the full year to be in the high single digits assuming current course and speed. We expect that adjusted EBITDA OpEx will be lower in the second half of the year compared to the first half as we complete our CTV platform migration, and remain focused on managing costs across the business. We anticipate full year adjusted EBITDA will be comparable or better than 2022 and that adjusted EBITDA margins will show meaningful improvement in the second half of 2023. Our full CapEx expectation is unchanged and we expect $40 million or less in 2023. And lastly, we continue to expect full year free cash flow to exceed $100 million. Q1 performance gives us a great start to 2023. And our differentiated market position as the leading independent sell-side advertising company puts us in a great place to accelerate growth and expand margins as the market improves. With that, let's open up the line for Q&A.
