Thanks, Melissa, and good morning, everyone. We reported a solid second quarter, achieving attractive top line growth in spite of the headwinds of the decline in fuel prices. As our results show, we continue to deliver with dependable execution that our employees, partners, customers and shareholders have come to expect. Now we'll start with the quarter results. For the second quarter, total revenue exceeded the midpoint of our guidance by $3 million despite lower fuel prices than we anticipated due to a combination of strong corporate payments purchase volume and a continuation of great results in our Benefits segment. Total revenue came in at a Q2 record level of $621.3 million, a 4% increase over Q2 2022, with more than 80% of revenue for the quarter recurring in nature. 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 40.3%, which is down from 42.3% last year largely driven by higher margins in the corporate payments and benefits offset by lower margins in the mobility segment. From an earnings perspective, on a GAAP basis, we had net income attributable to shareholders of $95.3 million in Q2 or $2.20 per share. Non-GAAP adjusted net income was $159.3 million or $3.63 per diluted share. I would like to underscore that our strong results were in spite of 2 significant macroeconomic headwinds we experienced over the past year. The first is the significant year-over-year decline in fuel prices that Melissa touched on earlier. The second is the large increase in interest rates year-over-year with a Fed funds rate increasing 350 basis points in that time period. While those rate increases impacted our operating and corporate debt costs, natural hedges in our business, including the HSA custodial cash balances allowed us to mitigate those increases. The diversity of our business creates the resiliency that Melissa has talked about and is a strength of the company. Now let's move to segment results, starting with mobility. Mobility revenue for the quarter was $340.2 million, a 10% decrease from the prior year. Fuel prices have retreated compared to the record highs seen last year after the Russian invasion of Ukraine with a domestic average fuel price in Q2 of $3.68 versus $4.98 in 2022. We estimate the year-over-year 26% fuel price drop decreased segment revenue by approximately $53 million. The lower fuel prices were the primary reason for the Mobility segment revenue decline, reducing revenue growth in the segment by 14% versus last year. We also had a $7.7 million onetime revenue item related to a contract amendment in the prior year, which contributed a further 2% to the revenue decline. Together, the fuel price declines and onetime revenue item from last year combined to result in a $61 million headwind year-over-year. However, at a more fundamental level, revenue this quarter continues to reflect a strong business model with stable volumes year-over-year combined with increased interchange and late fee rates. Payment processing transactions were roughly flat year-over-year which was in line with our expectations for the quarter. Local customers in the U.S. were flat with last year, while we had a small decline in over-the-road transactions due to difficult freight market conditions and the impact on small trucking fleets. In our over-the-road segment, we did see an increase in our direct bill transactions, a model utilized by larger trucking fleets, which is reflected in the other revenue line. We believe this reflects shipping volumes moving from smaller to larger fleets. The freight market is an area we continue to watch closely, and we believe the market has stabilized at low levels for now. Next, let's turn to late fees. As you can see in our metrics, the net late fee rate was up 10 basis points versus the prior year mostly as a result of the timing of the rapid increase in fuel prices last year, which depressed the rate. Finance fee revenue decreased 10%, even with a higher rate earned, the previously mentioned decline in fuel prices this year and a 30% slowdown in our factoring revenue, which is related to the freight market conditions I've just mentioned caused the decline in revenue. The net interchange rate in the Mobility segment was 1.25%, which is up 4 basis points from Q1 and 16 basis points over last year. The higher interchange rate compared to last year reflects benefits from the interest rate escalator clauses contained in various merchant contracts, the rate impact from lower fuel prices and higher rates earned from merchant contract renewals at favorable terms. The one-time item I mentioned earlier was a benefit to the rate in the prior year, offsetting these increases. The segment adjusted operating income margin for the quarter was 44.2%, down from 50.9% in Q2 2022. Decline in margin was due to higher operating interest expense based on higher interest rates and lower fuel prices, partially offset by significantly better credit losses. Let me briefly address the credit losses, which were better than our guidance range of 15 basis points of spend volume. The elevated loss rates in the over-the-road trucking business that we have seen over the past several quarters are abating. The improvement in delinquency rates noted last quarter are reflected in the improved losses we experienced this quarter. Likewise, the local fleet customers in the U.S. have a low loss rate when compared to historical norms. Fraud losses in this segment are also back close to a normal range following several quarters of elevated losses. As you will see in our guidance, we believe we will be back to normalized loss levels for the remainder of the year. Now turning to Corporate Payments. Total segment revenue for the quarter increased 21% to $121.9 million. Purchase volume issued by WEX was $22.9 billion, which is an increase of 34% versus last year. The net interchange rate in the segment was down 2 basis points sequentially, predominantly due to travel customers contributing a larger percentage of total volume versus Q1. Breaking this segment out further. Truck-related customer volume represented approximately 76% of the total spend and grew 44% compared to last year. Revenue from travel-related customers was up 50% versus Q2 2022. This reflects continued strength in consumer travel demand, and we are very pleased with these results. The Corporate Payments segment delivered an adjusted operating income margin of 54.4%, up from 50.8% in Q2 last year. There continues to be significant improvement in these margins as volume accelerates. Our business model here is very strong and revenue drop-through for this segment is high given our relatively fixed cost base. Finally, let's look at the Benefits segment. We continue to drive strong growth, resulting in Q2 revenue of $159.2 million. The $40.6 million increase represents 34% over the prior year. SaaS account growth was up 11% in Q2 versus the prior year. Benefits segment purchase volume increased 13%, leading to an 11% increase in payment processing revenue. We also realized approximately $42 million in revenue from the custodial HSA cash deposits that were invested by WEX Bank and funds held at third-party banks compared to $10.2 million last year. Approximately $27 million of the revenue increase in this segment is due to the average interest rate earned on these balances increasing from 1.57% last year to 4.33% this year. As I mentioned in the beginning of my remarks, this income makes us less sensitive to interest rates as a company as the revenue offsets higher interest expense in other parts of our business and serves as a natural hedge. The revenue is highly accretive to earnings, enabling us to perform well across a range of interest rate environments and providing some stability to navigate economic cycles. The Benefits segment adjusted operating income margin was 37.2% compared to 23.9% in 2022. The custodial revenue from the invested HSA cash deposits is the primary driver of the increase in margin. But if it's excluded from both periods, the core operating margin would still have increased 1%. Shifting gears 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 $901 million in cash. We have $893 million of available borrowing capacity and corporate cash of $194 million as defined under the company's credit agreement at quarter end. At the end of the quarter, the total outstanding balance on our revolving line of credit, term loans and convertible notes was $2.6 billion. During Q2, we began accessing the Federal Reserve bank term funding program as part of our accounts receivable funding strategy due to flexibility and low cost of the funds available to us. You will see this on the balance sheet as a $500 million increase in short-term debt, and it is included in our leverage ratio, but it is effectively being used as a replacement for broker deposits as part of our funding strategy. The leverage ratio, as defined in the credit agreement stands at 2.8x, which is within our long-term target of 2.5 to 3.5x. Our increase in leverage from Q1 is due to the use of the Fed bank term funding program, but this increased leverage is not expected to have any impact on our cost of or access to capital in the future because of our ability to quickly unwind the program and revert to brokered deposits. Next, I would like to turn to cash flow. WEX generates a significant amount of cash each year, using our adjusted free cash flow was $131 million through Q2, which is an increase of $265 million compared to 2022. Our primary use of free cash flow so far this year has been to repurchase shares. When the Ascensus transaction closes, we would expect to use some of our available borrowing capacity to close the deal. We will continue to manage capital allocation between organic investment and M&A and returning capital to shareholders. Finally, let's move to revenue and earnings guidance for the third quarter and full year. The second quarter was a very good quarter for us, and as a result, I am pleased to share that we are raising our guidance for 2023 to reflect those results. Starting with the third quarter, we expect to report revenue in the range of $629 million to $639 million. We expect ANI EPS to be between $3.65 and $3.75 per diluted share. For the full year, we expect to report revenue in the range of $2.5 billion to $2.52 billion. We expect ANI EPS to be between $14.15 and $14.35 per diluted share. For the full year, these updated ranges represent an increase of $35 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 increasing our expectations around travel volumes to match the environment we are seeing, including the assumption of reaching higher incentive tiers at the end of the year and further improvements in expected credit loss rates as a result of the actions we've taken over the last several quarters. We are providing this improved outlook despite our expectations of lower fuel prices which we expect to result in a $5 million to $10 million lower revenue and $0.15 of EPS in the back half of the year versus our prior fuel price assumption. As I complete my prepared remarks, I would like to emphasize how pleased we were with our Q2 results. We are also very pleased to be able to increase guidance despite a significant drop in fuel prices. We continue to execute well on both growing revenue and becoming more efficient serving our customers. With that, operator, please open the line for questions.
