Thanks, Melissa, and good morning, everyone. We reported a strong first quarter with record high Q1 revenue. Our adjusted EPS results show continued execution against our strategic initiatives even against a year-over-year decline in fuel prices. Now let's start with the quarter results. For the first quarter, total revenue was $652.7 million, a 7% increase over Q1 2023, with more than 80% of revenue for the quarter recurring in nature. We had strong contributions from both Corporate Payments and Benefits, while lower fuel prices impacted reported growth in the Mobility segment. As a reminder, we define recurring revenue as payment processing and account servicing revenue, revenue from our factoring business, income from custodial HSA cash assets, transaction processing fees and other smaller items. In total, adjusted operating income margin for the company was 38.5%, which is up from 37.6% last year, driven by margin increases in both Corporate Payments and Benefits segments. From an earnings perspective, on a GAAP basis, we had net income of $65.8 million in Q1 or $1.55 per share. Non-GAAP adjusted net income was $146.7 million or $3.46 per diluted share, which is an increase of 5% over last year. Our first quarter results were solid and set us up well for the remainder of the year, as we continue to navigate a year-over-year decline in fuel prices as well as a significant increase in debt costs due primarily to higher interest rates. Like we have discussed in previous quarters, our HSA custodial cash balances allow us to mitigate the impact of higher rates. As a reminder, we also exited our interest rate hedge positions in December, leading to an increase in interest cost this quarter. Exiting our interest rate swaps in December resulted in an $11 million cash impact to interest expense and a 7% drag on earnings per share. In addition, the foreign exchange rates and lower fuel prices resulted in a negative $20 million impact to revenue this quarter versus last year or an approximate 9.5% drag to earnings per share. Our ability to continue to grow earnings per share despite the drag from exiting the swaps and lower fuel prices is a testament to our diverse vertical focused businesses, strong recurring revenue and balanced interest rate exposure, allowing us to sustain durable through the cycle revenue and earnings growth. Now let's move to segment results, starting with Mobility. Mobility revenue for the quarter was $339 million, a 1% decrease from the prior year. Fuel prices are strong, but have retreated compared to last year, with the domestic average fuel price in Q1 of $3.56 versus $3.86 in 2023. The Q1 fuel price was slightly higher than our guidance, but the benefit we received in the U.S. was almost entirely offset by $2 million of negative spreads in Europe versus our expectation. While Mobility revenue declined approximately $3 million year-over-year, fuel prices had a large impact. The year-over-year 8% fuel price decline and reduced spreads in Europe decreased segment revenue by an estimated $21 million or 6%, while the underlying business continued to perform well. As we expected, excluding the change in fuel prices, revenue growth accelerated from Q4. Similar to last quarter, payment processing transactions remained roughly flat year-over-year, which was in line with our expectations. Local customers in the U.S. were approximately flat compared to last year, and over the road payment processing transactions were slightly above year ago levels. As Melissa noted, this is the first quarter in some time that OTR transactions have increased, reflecting stabilization in that business. Note that despite the fact that this was a leap year, we actually had one less business day in Q1 than last year. Overall, we were pleased that both payment processing transactions and total transaction growth rates improved from Q4 2023. Next, let's turn to late fees. The net late fee rate decreased 4 basis points versus the prior year. Finance fee revenue decreased $10 million or 13%, which reduced segment revenue in total by 3%. The previously mentioned decline in fuel prices, a 20% decline in the number of late fee instances that a 7% slowdown in our factoring revenue caused the decline in finance fee revenue. We believe the decline in late fee instances reflects the tighter credit policies that we have put in place. While these tighter policies reduce our late fee revenue, they have also resulted in significantly lower credit losses and taken holistically our positive earnings impact to the company. I will touch further on credit losses in a moment. The net interchange rate in the Mobility segment was 1.31%, which is up 8 basis points over our 2023 net interchange rate. The increase reflects continued benefits from the interest rate escalated causes contained in various merchant contracts, the rate benefit from lower domestic fuel prices and higher rates earned from merchant contract renewals at favorable terms. The Mobility segment adjusted operating income margin for the quarter was 38.6%, down from 40.5% in Q1 2023. The decline in fuel price this year is the primary reason for the lower margins. Moving on, credit losses decreased $24 million in the Mobility segment versus last year, and were in line with our guidance range at 15 basis points of spend volume, which compares to 32 basis points last year. Loss improved significantly compared to last year as expected. The changes that we made to our credit policies a year ago have had the intended impact in terms of reducing losses, especially with over-the-road trucking customers. The year-over-year decline of 17 basis points in credit loss rates more than makes up for the 4 basis point decline in our net late fee rate, and underscores the positive overall impact from the credit changes we made a year ago. Turning now to Corporate Payments. Total segment revenue for the quarter increased 17% to $122.5 million. Purchase volume issued by WEX was $23.9 billion, which is an increase of 29% versus last year. The net interchange rate in the segment was down 9 basis points sequentially, related to the timing of revenue recognition for network incentives earned in Q4 of last year. We continue to see strength in consumer travel demand that drove strong results in Corporate Payments. Travel-related customer revenue grew 30% compared to last year. The interchange rate for travel-related customers is down from Q4 due to the timing of incentive recognition. Outside of Travel, our Non Travel customer revenue was up 7%, driven by a 26% increase in purchase volume, showing some reacceleration in our partner channel and continued positive growth in our direct channel revenue. Similar to last quarter, over half our Non Travel corporate payment revenue growth came from our direct channel. The Corporate Payments segment delivered an adjusted operating income margin of 52.7%, up from 46.9% in Q1 last year, driven by continued acceleration in volume. Finally, let's look at the Benefits segment. We again achieved strong results in this segment with Q1 revenue of $191.2 million, which is an increase of $26.3 million or 16% over the prior year. As we expected, SaaS accounts were flat in Q1 versus the prior year, with the loss of the Medicare Advantage customer that we mentioned last quarter. Core market dynamics of this business continue to be strong as exemplified by the underlying SaaS account growth, excluding the declines in Medicare Advantage accounts, which was 8% year-over-year. The Benefits segment purchase volume increased 10%, leading to a 6% increase in payment processing revenue. We also realized approximately $51 million in revenue from the custodial HSA cash deposits that were invested by WEX Bank and from funds held at third-party banks compared to $37 million last year. Approximately $8 million of the revenue increase in the Benefits segment is due to the average interest rate earned on these balances, increasing from 4% last year to 4.8% this year. The Benefits segment adjusted operating income margin was 41.5% compared to 39.1% in 2023. The custodial revenue from the invested HSA cash deposits has very high incremental margins. It is the primary driver of this increase. Now I will provide an update on the balance sheet and our liquidity position. We remain in a healthy financial position and ended the quarter with $780 million in cash. We have $463 million of available borrowing capacity and corporate cash of $176 million as defined under the company's credit agreement at quarter end. The total outstanding balance on our revolving line of credit and term loans was $3.2 billion. The leverage ratio, as defined in the credit agreement, stands at 2.6x, which is near the low end of our long-term target of 2.5 to 3.5x. Leverage generally increases slightly in the first quarter of each year. Our ability to invest in the business and return capital to shareholders while also maintaining conservative debt levels puts us in an enviable position. Next, I would like to turn to cash flow. WEX generates a significant amount of cash each year. Using our definition, adjusted free cash flow was negative $205 million in Q1. The first quarter of each year is seasonally low for us, and the timing of the end of the quarter falling on a weekend resulted in an estimated $190 million cash flow impact and caused an even larger negative number than normal for the quarter. We expect this will reverse in Q2. Our primary discretionary use of cash so far this year has been to repurchase shares. We repurchased 353,000 shares at a total cost of $74 million during Q1. Since restarting our share repurchase program in 2022, we have repurchased approximately 3.9 million shares with an average cost of $169 per share. Looking forward, we will continue to manage capital allocation between organic investment, M&A and returning capital to shareholders. Finally, let's move to revenue and earnings guidance for the second quarter and full year. The first quarter was another good quarter for us and as a result of improvement in some macro factors, I'm pleased to share that we are raising our guidance for 2024 to reflect those factors and trends. Starting with the second quarter, we expect to report revenue in the range of $675 million to $685 million. We expect ANI EPS to be between $3.75 and $3.85 per diluted share. For the full year, we expect to report revenue in the range of $2.73 billion to $2.77 billion. We expect ANI EPS to be between $16.10 and $16.60 per diluted share. For the full year, these updated ranges represent an increase of $30 million in revenue and $0.20 of EPS compared to the midpoint of our previous guidance. The major moving pieces compared to our prior guidance are updated fuel price and interest rate assumptions and the impact of share repurchases completed. Consistent with our prior guidance, we expect Mobility revenue growth to accelerate through the year, as we lap credit changes that caused higher attrition and lower finance fee revenue. As we noted last quarter, we are also implementing a number of pricing changes that will help the second half of the year. We also expect corporate payments revenue growth to slow as we progress through the year. In addition, we expect a greater proportion of our cost savings program to flow through to net income as we have front-loaded the reinvestment we intended to make. In conclusion, we delivered another quarter of growth in our financial results, and I'm especially proud that we were able to do this in the uncertain economic environment that we are operating in. With that, operator, please open the line for questions.
