Earnings Call Analysis

WEX Reports Strong Results and Positive Outlook

In 2023, WEX reported a record high of $2.5 billion in revenue, an 8% increase, outperforming amidst fuel price and forex headwinds. Adjusted net income per share rose by 9%, with 13% revenue growth and 21% adjusted income growth when excluding these impacts. The fourth quarter saw a 7% revenue boost and a 11% adjusted EPS increase. Significant growth in Corporate Payments with several key contracts and Benefits, with over 8 million HSA accounts, was highlighted. WEX's strategic focus includes EV transition, with initiatives to support mixed fleet management. Anticipating headwinds like lower GDP growth, WEX forecasts 6-8% revenue growth for 2024, including Payzer's full-year impact. Adjusted EPS is expected to grow 7-11%, or 13-17% excluding fuel price and forex impacts, with targeted cost savings of $100 million by year-end.

Continued Resilience and Record Highs Despite Economic Headwinds

In a challenging economic environment characterized by higher interest rates, inflation, a freight recession, and lower fuel prices, WEX Inc. achieved impressive growth in 2023. The company's resilient business model is bolstered by an exceptional team and strategic positioning for long-term success. Over the past decade, WEX has maintained a robust revenue compound annual growth rate (CAGR) of 14%. The past year saw record revenues of $2.5 billion, up by 8%, and an increase of 6% in total volume processed to $225 billion. Even when adjusting for lower fuel prices and exchange rate variations, revenue and adjusted net income per share still grew 13% and 21%, respectively, hitting or surpassing long-term targets.

Solid Q4 Performance Driven by Corporate Payments and Benefits

WEX's fourth-quarter results demonstrated sustained momentum with a 7% revenue increase to $663 million and an 11% growth in adjusted EPS. Adjusted net income per share hit $3.82, marking a 23% rise minus fuel and FX impacts. The company's robust quarter was fueled by gains in Corporate Payments' purchase volumes, seeing a 33% surge largely due to strong travel customer activity, and in the Benefits segment, which solidified its cloud transition and now hosts over 8 million HSA accounts.

Mobility Segment's Positive Impact and Strategic Moves

The Mobility segment of WEX felt the positive effects of improved credit policies, which led to significant wins and expansions, adding around 121,000 new vehicles via prestigious contracts. WEX leads the charge in helping businesses transition to energy-efficient fleets, offering innovative products to simplify mixed fleet management. With extensive customer reach, the company is a go-to for managing over 19.3 million vehicles globally. To further bolster its offerings in adjacent markets, WEX acquired Payzer, aligning top-notch payment solutions with integrated software services, focusing on field service management companies in the mobility sector.

Efficiency Driven Growth & Cost Savings

Beyond growth, WEX emphasizes profitability, targeting $100 million in cost savings by the end of 2024. Already achieving $70 million ahead of schedule, these savings will be strategically reinvested in enhancing digital products, technology, and capability building. The company's tech-driven initiatives, particularly in artificial intelligence (AI), are set to streamline operations—from credit decisions and fraud detection to benefit claim processing—expected to handle over 800,000 claims using AI in the coming year.

Forecasting Strong Revenue Growth and EPS Accretion

Looking ahead to 2024, WEX stands resilient in the face of economic challenges. The company forecasts a 6% to 8% revenue growth, including headwinds from lower fuel prices. Growth in Mobility is anticipated to continue, and Corporate Payments is expected to drive strong accretive EPS performance. The commitment to free cash flow strengthens the ability to invest in product leadership and share buybacks, all while maintaining a healthy balance sheet.

Robust Q4 2023 Financials and Segment-Specific Outlook

WEX delivered a strong close to 2023 with Q4 revenues reaching $663.3 million, up 7.2% from the prior year, and an adjusted net income swell to $163.9 million. The Mobility segment, despite a dip due to lower fuel prices, achieved higher interchange rates and reported better credit quality, signaling reduced exposure to fuel price volatility moving forward. The Corporate Payments arena accelerated with a 22% increase in revenues propelled by travel demand and adoption of virtual cards. Benefiting from new acquisitions like Payzer, the impressive company-wide margin increases reflect efficiencies and strategic foresight.

Earnings Call Transcript 2023-Q4

[Operator]

Thank you for standing by, and welcome to the WEX Q4 2023 Earnings Call. I would now like to welcome Steve Elder, SVP of Global Investor Relations to begin the call. Steve, over to you.

[Steven Elder, executive]

Thank you, operator, and good morning, everyone. With me today is Melissa Smith, our Chair and CEO; and Jagtar Narula, our CFO. The press release we issued earlier this morning and a slide deck to walk through our prepared remarks have been posted to the Investor Relations section of our website at wexinc.com. A copy of the release has also been included in an 8-K we filed with the SEC earlier this morning. As a reminder, we will be discussing non-GAAP metrics, specifically adjusted net income attributable to shareholders, which we refer to as adjusted net income, or ANI, adjusted operating income and related margins as well as adjusted free cash flow during our call. Please see Exhibit 1 of the press release for an explanation and reconciliation of these non-GAAP measures. The company provides revenue guidance on a GAAP basis and earnings guidance on a non-GAAP basis due to the uncertainty and the indeterminant amount of certain elements have been in reported GAAP earnings. I would also like to remind you that we will discuss forward-looking statements under the Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those forward-looking statements as a result of various factors, including those discussed in our press release and the risk factors identified in our annual report on Form 10-K for the year ended December 31, 2022, filed with the SEC on February 28, 2023, and in our quarterly reports on Form 10-Q and subsequent SEC filings. While we may update forward-looking statements in the future, we disclaim any obligations to do so. You should not place undue reliance on these forward-looking statements, all of which speak only as of today. With that, I'll turn the call over to Melissa.

[Melissa Smith, executive]

Thank you, Steven, and good morning, everyone. We appreciate you joining us today. Before diving into our results, I'd like to take a moment to reflect on 2023. As I've said in prior quarters, our business model is resilient, and it delivers strong results in a variety of environments. This is true over the past 10 years, during which time we have delivered a revenue CAGR of 14%. I am very proud of what we've accomplished in 2023 as we continue to achieve our long-term growth targets despite macroeconomic uncertainty, higher interest rates, higher inflation rates, a freight recession and lower fuel prices. Our incredible team of Wexers has consistently risen to the occasion. Further positioning WEX for long-term success and demonstrating our ability to grow, to deliver that growth profitably and to advance our strategic priorities.

Let me start with the full year results. Revenue of $2.5 billion for the year was a new record high and grew 8% compared to the prior year despite a headwind of 5% from fuel prices and foreign exchange rates. Full year total volume processed was $225 billion, an increase of 6% year-over-year. Adjusted net income per share grew 9% year-over-year. Excluding the impact of lower fuel prices and foreign exchange rate differences, revenue grew 13% and adjusted net income per share grew 21%. Both of these growth rates were within or above our long-term target ranges as we continue to deliver strong results in the face of the headwinds I just mentioned. I'm particularly pleased about the strong performance in benefits and corporate payments, which further demonstrates the resilience of our model across many environments.

Now turning to fourth quarter results. We delivered revenue of $663 million for the quarter, an increase of 7%. Excluding the impact of fluctuations in fuel prices and foreign exchange rates, Q4 revenue grew 11%. Total volume processed across the organization in the fourth quarter grew 6% year-over-year to $56 billion, driven by the strong performance in corporate payments and benefits. Strong quarterly revenue, high margin drop-through on volumes and share repurchases resulted in adjusted net income per diluted share of $3.82 an increase of 11% compared to the same quarter last year. Excluding the impact of fluctuations in fuel prices and foreign exchange rates, Q4 adjusted EPS grew 23%. In Corporate Payments, purchase volumes grew 33% year-over-year, primarily due to continued strength from our travel customers. We had a number of significant contract renewals in the quarter, including [ Kiwi ] and on the [ Beaton ] Europe and Flight Center in Australia. WEX continues to outpace the growth of the travel market. We're having success gaining additional pockets of spend within our existing customer base and volume growth continues to benefit from the market transitions to settling hotel transactions with virtual cards.

In the Benefits segment, the full transition to the public cloud positions us to improve our agility and platform strength going forward. Following open enrollment, we now have more than 8 million HSA accounts on our platform making us one of the largest providers in the country. Since we closed the acquisition of Extensive Health and Benefits line of business in September, we have quickly integrated our team. Census technology complements ours well, increasing our scale in the benefit space and expanding our benefit product offerings with their Affordable Care Act compliance independent verification capabilities. Finally, in our Mobility segment, we continue to see the positive impact from our enhanced credit policies. We were also pleased with strong sales performance, including a number of key contract wins and renewals in the quarter, adding approximately 121,000 new vehicles in signing wins with Smith Transport, Estes Express lines, Quality Carriers and [ Pods ] to name a few.

Overall, I'm proud of the strong progress we made executing against our strategic themes throughout 2023, which positions us for 6 steps in 2024 and beyond. A top priority for us as a company is leading in the energy transition for our mobility customers. Currently, we're focused on helping businesses navigate the energy transition and manage their vehicles in an increasingly complex mixed fleet world with over 600,000 customers worldwide, including more than 19.3 million vehicles service globally as of the fourth quarter, our partners and customers will first look to WEX for help in simplifying the process of building and managing mix fleet. While the pace of transition remains fluid, we are meeting our customers where they are in their EV journeys. As part of our EV product suite, we have a new white-labeled offering help fleet managers determine which vehicles and roots may make sense to transition to EVs. In cases where it does make sense, like a sales rep driving as Sedan and returning home to charge each night, there can be substantial savings for the fleet operator. Our understanding of these dynamics uniquely positions WEX, help customers both navigate the decision to transition and effectively manage their fleets once they do.

We've also launched products in the market, designed to help facilitate on-route charging at public locations as well as at at-home reimbursement capabilities. Later this year, we plan to launch depot charging solutions for companies that intend to use their own infrastructure. Our EV product suite gives our customers a simple consolidated platform for mixed fleet greatly simplifying the job as the fleet manager. Similar to the EV transition, a strategic priority has been to expand into near adjacent addressable markets, increasing our TAM. In November, we completed our acquisition of Payzer, a leading cloud-native field service management software. As we integrate Payzer into the WEX business, we expect the platform to strengthen our relationships with customers in our mobility vertical, allowing us to match our world-class payment capabilities with integrated software that creates durable value to our customer base. We're excited to deepen and expand our offerings to approximately 150,000 mobility customers that operate field service management companies. So far, we have completed the initial stage of integration and launched our first marketing efforts targeted at current WEX customers.

Over the next few quarters, we will test and learn from this initiative, and we will continue to be prudent in our decisions to allocate additional capital to this effort. That said, we're excited about the Payzer opportunity, and I look forward to providing updates on our progress going forward. Across each of our businesses, we are focused not only on driving growth but on delivering that growth profitably. To that end, we remain well positioned to generate $100 million in run rate cost savings exiting 2024. Last quarter, we said we were on track to achieve $70 million of cost savings on a run rate basis by the end of 2023. I am proud to say we have accomplished this goal, which was ahead of our original expectations. We have high confidence in achieving the full $100 million of cost savings in 2024. With these savings, we plan to let half flow through to earnings, which we will see in our expectations for 2024 and reinvest the remainder in the business to enhance our capabilities, including digital products, technology and risk management capabilities and tools. We also continue to drive technology innovation throughout the business. The work we are doing is delivering results, and we're receiving cost savings coming through our margins. In 2023, we focused heavily on determining how AI could both optimize our business and the business of our customers. We've invested in dozens of projects around developing these capabilities. For example, we are currently using internally developed AI technology to assist in making credit decisions and detecting fraud. We believe this technology helped drive the substantial credit loss improvement that we have seen over the last 2 quarters.

We're also piloting several new initiatives to finance productivity and drive efficiencies in our sales teams by using AI to prioritize the leads most likely to convert and by prioritizing deals in the sales pipeline to maximize focus on impactful deals. We are also using AI to help process benefit claims, which drives efficiency and improved customer experience by processing claims on the same day. We processed greater than 350,000 claims last year and continue to expand use cases. We expect to process more than 800,000 plans this year using AI. Beyond this, we have a slate of digital product releases expected throughout 2024 and look forward to updating you on these developments over the coming months. We expect these margin accretive initiatives and others to further bolster our ability to generate significant cash flow conversion, and we continue to view share repurchases as an attractive proposition.

We're in the privileged position to be able to make strategic growth investments in our business and buy back shares, all while maintaining a solid balance sheet with low leverage. Jagtar will provide more detail on our 2024 guidance in a moment, but I'd like to share a few high-level takeaways as we look ahead. First, WEX is incredibly resilient to economic conditions and is well positioned for continued strong revenue growth. You will note in our guidance that we have made assumptions that include continued headwinds, such as lower than normal U.S .-GDP growth and further depressed steel prices. Despite these headwinds, we expect 2024 revenue growth in the 6% to 8% range including a 2% headwind for lower fuel prices. All segments of the business will benefit from the full year impact of our sales activity in 2023. Within our Mobility segment, we expect continued strong sales momentum, benefit from pricing actions, stabilization in the portfolio from the credit policy changes made a year ago, in the benefit of a full year of Payzer growth.

Within our Benefits segment, we expect continued sales through our distribution channels. We expect continued growth in custodial assets and our organic customer growth and the census acquisitions. Last, but certainly not least, we expect strong growth within our Corporate Payments segment built on continued strength in our embedded payment solutions, inclusive of both share of wallet capture in our Travel and Partner Businesses as well as our investments in scaling our direct sales force becoming more meaningful to the segment. Second, we continue to be focused on delivering accretive EPS. This includes the high marginal contribution of incremental revenue to our businesses, our reengineering efforts that are delivering efficiencies across our enterprise and pricing optimization work that yields strong drop through to our bottom line.

Finally, our strong adjusted free cash flow underpins our ability to drive shareholder value. It enables us to invest in our market-leading products and solutions as well as invest in our share repurchase program in our disciplined M&A program, all in maintaining a healthy balance sheet. As I look across our business, I am confident in WEX's future, our momentum in the marketplace, and our continued ability to deliver our long-term aspirations. With that, I'll turn it over to Jagtar to walk through this quarter's financial performance in more detail. Jagtar?

[Jagtar Narula, executive]

Thank you, Melissa, and good morning, everyone. As you just heard, we again delivered strong financial results this quarter while continuing to make progress on our strategic objectives. The financial results in 2023 demonstrated the resiliency of the business in the face of a number of economic headwinds. Let's start with the quarter results. Total revenue came in at $663.3 million, a 7.2% increase over Q4 2022 with more than 80% of revenue for the quarter recurring in nature. This exceeded the midpoint of our guidance by $8 million. Half of this outperformance was due to the contribution of Payzer, which closed on November 1 and was not included in our guidance, while the other half was a variety of small beneficial items. In total, adjusted operating income margin for the company was 39.6%, which is up from 38.5% last year. High incremental margins on corporate payments volume and interest earned on custodial cash balances as well as significantly improved credit and fraud losses were the primary drivers of the margin increase.

From an earnings perspective, on a GAAP basis, we had net income attributable to shareholders of $84.9 million or $1.98 per diluted share in Q4. Non-GAAP adjusted net income was $163.9 million or $3.82 per diluted share, and this represents an 11% increase over the prior year. I would like to take a moment to reflect on these results in the context of the overall macroeconomic environment. Fuel prices were down 13% year-over-year in Q4, while the federal funds rate was up 100 basis points from the end of Q4 2022 to the end of Q4 2023. Our cost of financing and operating interest was up almost $35 million year-over-year. Yet we grew revenue and earnings significantly which reflects the reduced impact of fuel prices and interest rate volatility on our overall results and demonstrates the resiliency we have talked about repeatedly. Now let's move to segment results, starting with Mobility. Mobility revenue for the quarter was $350.1 million, a 5% decrease compared to the prior year. The domestic fuel price in Q4 was $3.76 versus $4.34 in Q4 2022. This decline in fuel prices reduced segment revenue by approximately $24.9 million.

In addition, mobility revenue growth was impacted by lower late fees, which I will discuss in a moment. These lower late fees reflect the changes we made to credit policies that have dramatically improved credit losses and financially outweigh the impact of lower late fee revenue. The net interchange rate in mobility was 1.26%, which is up 15 basis points from the prior year. The lower fuel prices compared to last year contractual increases due to higher interest rates and renegotiated contracts with some of our merchants led to the increase in the net rate. The increase in the net interchange rate combined with growing volumes over the past several years also means the sensitivity to changes in fuel prices is increasing and now stands at $20 million of revenue impact and a $0.30 EPS impact for an annualized $0.10 change in fuel prices. It is important to note that despite the higher gross EPS sensitivity to fuel which reflects the growth and success of our mobility business. Our overall earnings sensitivity to fuel price is lower than the past as nonfuel-related revenue is an increasing portion of our overall earnings mix.

As you see in our metrics, while the net late fee rate increased versus Q3, it was below the prior year results. Overall, finance fee revenue was down 20% due to lower fuel prices and 28% decline in the number of latency instances. Much of this decline is from a new portfolio that transitioned to us last year which had higher late fee instances during the transition period, while the remainder we attribute to the stricter credit policies I mentioned earlier. Again, emphasizing that the improvement in credit losses far outweighs this lost late fee revenue. The segment adjusted operating income margin for the quarter was down 2.1% compared to last year at 43.0%. Lower fuel prices and higher interest rates hurt operating margins, although this was partially offset by significantly lower credit loss rates. In addition, the acquisition of Payzer, which contributed $4.3 million in revenue with essentially 0 adjusted operating income decreased its segment margin by 60 basis points.

Turning now to Corporate Payments. Total segment revenue for the quarter increased 22% from the prior year to $135 million. Purchase volume issued by WEX was $22.8 billion, which is an increase of 33% versus prior year. The net interchange rate in this segment was up 10 basis points sequentially at 52 basis points, predominantly due to the recognition of network incentives based on full year performance. Breaking this segment down further. Travel-related customer volume was $16.2 billion and grew 40% compared to last year. Revenue from travel-related customers was up 39% versus last year. This reflects continued strength in consumer travel demand in the U.S. and Europe as well as growing adoption of virtual cards and travel. We believe that there is more room for growth as our OTA customers continue to emphasize their merchant model, and we expand the types of payments that we are able to support. Nontravel-related customer purchase volume grew 21% versus last year, and revenue was up 5%.

Volume growth was led by continuing strength in the partner channel, but importantly, approximately half the revenue growth came from our direct channel. Our direct business is an important channel that we have invested in over the last year and we are starting to see the positive results of this segment. The segment adjusted operating income margin was up 10.5% over the last year to 58.4%. There has been significant improvement in these margins during the year as volume accelerated. In fact, this is the second quarter in a row where more than 100% of the year-over-year revenue increase flowed through to adjusted operating income margin. Finally, let's take a look at the Benefits segment. We continue to drive strong growth in Q4 with revenue of $178.2 million. This represents an increase of $37.5 million or 27% over the prior year. Approximately half the revenue growth is due to contributions from custodial assets, and the remainder is from the Ascensus acquisition, increases in the account base and purchase volume growth.

SaaS account growth was 7% in Q4 versus the prior year. Benefits segment volume increased 10%, leading to a 5% increase in payment processing revenue. Custodial cash assets, including those on and off balance sheet, were $3.9 billion on average in Q4 versus $3.5 billion last year. Representing an increase of 13%. Of the $3.9 billion total, approximately $1 billion was held at third-party banks with the remainder held at WEX Bank. We realized approximately $45.3 million in revenue in total from these deposits in Q4 versus $25.6 million last year. Although market interest rates declined during Q4, the blended yield of 4.6% was consistent with Q3. Compared to last year, the higher yield of those assets contributed $11.1 million in revenue, while the increase in balances contributed $8.6 million. In the first full quarter of ownership, census contributed $10.7 million of revenue, which was in line with our expectations for the quarter. The integration process is going well. Recall that census was a customer prior to our acquisition. So all accounts were already on our technology platform came through the remainder of the integration planned during 2024.

The Benefits segment adjusted operating income margin was 33.2%, compared to 28.1% in 2022. The high flow-through on the revenue from the invested HSA deposits is the primary driver of the increase in margins. 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 $976 million in cash. We have $731 million of available borrowing capacity on the revolver and corporate cash of $172 million as defined under the company's agreement at quarter end. The total outstanding balance on our revolving line of credit and term loans was $2.9 billion. The leverage ratio, as defined in the credit agreement stands at 2.5x and which is at the bottom end of our long-term target of 2.5x to 3.5x. In December, we exited our interest rate hedge positions leading to an immediate cash benefit of $50 million.

As discussed in prior calls, the company-wide net exposure to changes in interest rates has declined as we've grown the custodial cash assets in our Benefits segment. As a result, we determined that these hedges were unnecessary and we could exit them at favorable terms. Exiting the hedges accelerated the cash benefit we expected to see from the hedges to upfront rather than over time, which we intend to return to shareholders through share repurchases, and we have already repurchased $35 million to date through last week in 2024. As a result, we will see an increase in interest costs in 2024, especially in Q1 when rates are expected to be highest and with the elimination of the hedges that were already set to expire midyear. I want to emphasize this reflects our belief in the time value of money benefit of receiving the cash earlier than we would have otherwise and returning this cash sooner to our shareholders. Going forward, we intend to continue to evaluate our overall interest rate exposures annually and make adjustments to our hedging strategy as necessary.

During January, we successfully repriced $1.4 billion of term loans, reducing the spread over sulfur by 25 basis points and removed the credit spread adjustment. This will lead to interest savings of more than $5 million in 2024 on this price of debt. There were no other changes below the agreement. Next, I would like to turn to cash flow. WEX generates a significant amount of cash. Using our definition, adjusted free cash flow is $517 million for 2023. This compares to our adjusted net income of $646 million. A reminder, as I have discussed previously, that rapid fuel price declines at the end of 2022 increased adjusted free cash flow by about $150 million to $175 million that year, which reversed during 2023. Taking this into account, adjusted free cash flow for 2023 was slightly less than adjusted net income, which is what we would normally expect. We are committed to driving strong cash generation and deploying it by both repurchasing our own shares and investing in our business with an overall goal of maintaining strong long-term growth rates.

For the year, we repurchased 1.7 million shares at a total cost of approximately $295 million, including approximately $150 million in the fourth quarter. As a reminder, we also extinguished a $310 million convertible debt in Q3, which further reduced fully diluted share count by 1.55 million in Q4 compared to the prior year. Going forward, we expect to continue to allocate a portion of adjusted free cash flow to repurchase shares. Finally, let's move to 2024 revenue and earnings guidance for the first quarter and the full year. Starting with the first quarter. We expect to report revenue in the range of $650 million to $660 million. We expect adjusted net income EPS to be between $3.40 and $3.50 per diluted share. For the full year, we expect to report revenue in the range of $2.7 billion to $2.74 billion. We expect adjusted net income EPS to be between $15.90 and $16.40 per diluted share.

Let me spend a couple of minutes going through some of the larger assumptions in our guidance. First, a couple of high-level macro assumptions. We are basing our guidance on U.S. GDP growth of around 1.5% for the year, which we have taken into account in our growth expectations. We are also expecting interest rates to decline in line with the market, which implies 5.5 point rate cuts during the year. We have not included any future M&A activity or share repurchases, except as we have already announced them. Mobility revenue growth, excluding the change in fuel prices, is expected to be at the high end of our long-term target, which is 4% to 8%, including approximately 2% for the contribution in Payzer. Fuel prices are expected to be lower in 2024 than in 2023, which is a headwind to revenue and earnings that is embedded in our guidance. We are assuming an average fuel price of $3.50 in the first quarter, and $3.55 for the year, which compares to $3.86 for Q1 2023 and $3.82 for the full year 2023.

The fuel price decline is expected to reduce revenue and earnings per share by approximately $18 million and $0.27 per share in Q1 and $54 million and $0.81 per share for the full year compared to 2023 using the new sensitivity that I mentioned earlier. Again, this fuel price impact is already embedded in our guidance. Melissa mentioned some of our growth drivers earlier, which I will reiterate, including strong continuing sales engine, pricing optimization, full year benefit impact of Payzer and stabilization in the portfolio from the credit policy changes made a year ago, which will also reduce the revenue drag from lower late fees that we saw in 2023.

Corporate Payments segment is expected to grow high single digits. Similar 2023 results, we expect the net interchange rate to come down slightly, mainly due to customer mix. We see significant demand for travel and expect to improve nontravel revenue growth in 2024. Finally, the Benefits segment is expected to grow 10% to 15%. We have completed the open enrollment season, giving us confidence in the continued growth of this business. Anticipated growth in custodial assets and tailwinds in from organic growth and the census acquisition are expected to more than offset the loss of an individual Medicare Advantage customer. We are on track to remove $100 million of operating costs on a run rate basis by the end of 2024 as we previously outlined.

We expect adjusted operating income margins to trend up through the year as we get the benefit of these cost savings measures and the impact of pricing initiatives that -- and scale that Melissa spoke about earlier. As I mentioned earlier, our decision to exit the swaps, pulled cash forward, but also results in higher interest expense in 2024. The impact is $0.19 per share in Q1 and $0.52 per share for the full year. Again, this is reflected in our guidance. As we have discussed, we aim to balance our fixed and floating rate assets and liabilities such that we would not expect material changes to overall adjusted earnings this year if there are changes in benchmark interest rates, although there could be impacts to individual segments. All of this leads to EPS growth in the range of 7% to 11%, isolating out our fuel price degradation and FX, we would expect adjusted EPS growth to be in the range of 13% to 17%.

As I complete my prepared remarks, I would like to emphasize again how pleased we were with our results Q4 and our outlook for 2024. We have great confidence in our ability to win new customers, expand with existing customers and bring new products to market all leading to continued long-term growth of the company. With that, operator, please open the line for questions.

[Operator]

[Operator Instructions]. Our first question comes from the line of Darrin Peller with Wolfe Research..

[Darrin Peller, analyst]

Maybe just touch a little more on the confidence in underlying just fundamentals given Corporate Payment yields fell a bit year-over-year? And maybe just a little more on the Benefits segment. When you think about guidance relative to recent trends, I'd love to hear a little more color on that first, if you don't mind.

[Melissa Smith, executive]

Sure. Good morning. And I'm going to start -- of our confidence in next year is line of sight. We ended 2023, we grew revenue 13%, including fuel prices in FX. And if you look at the midpoint of our guidance for 24, it's 9% on the same basis. And going into that, if you go into -- I won't go into the segment now, Jagtar, if he wants to. But that across the business and one of the most important things for us is to continue the sales momentum that we had in 2023. We'll get a benefit of the sales tail of what we sold this year, and we expect our sales professionals to continue to deliver in 2024. We also have pricing levers that we're going to continue to use, which we did in mobility in '23, and we'll continue to in '24. We'll Get the benefit of the annualization on the changes we made from our credit policies, which will give us a lift from a comparability standpoint, both on late fees and on attrition. And then we'll get a full year benefit of the acquisitions. And specifically, you asked about corporate payments. On the corporate payment side, we are expecting to see lift on the nontravel part of our business, and you can see that has come true sequentially. Each quarter, we've come up a little bit over the last couple of quarters, and we're expecting that momentum to continue into 2024. And that's coming from the pipeline that we have on our embedded payments product as well as the success we've had with our direct sales force, which is becoming a more meaningful part of the business. And then we expect our travel business to become a little bit more muted in -- and from a growth perspective in 2024 compared to '23, which was bullish we're coming off a 40% spend volume growth in the fourth quarter of 2023. And so we're expecting, as you go through the course of 2024, that, that growth will moderate.

[Darrin Peller, analyst]

Okay. All right. That's a great -- Go ahead, Jagtar. I'm sorry.

[Jagtar Narula, executive]

No. I was just going to -- I think Melissa had all the key points. I was just going to reiterate, I think, Darrin, you are from benefits and corporate payments and the question, I would say, of benefits, right? In '23, we've got a lot of benefit from interest rates of our 32% growth in '23, a little bit more than half of it came from rates, not expecting that to repeat in '24. So if you take that out, and look at what's left, right? We've got a little bit of benefit from census. I mentioned the customer that's leaving. But if you net those two out, what you find is that the underlying business continues to perform as it did in '23, and we feel really good about that. And then on the corporate payment side, right, as Melissa mentioned, a little more growth in our non-travel business mainly because we've got good visibility to the partners that we work with as well as increase in fine our direct business. I pointed out in my prepared remarks that, that direct business was about half the growth in the nontravel part this quarter. And so we're really pleased with the events we've made there and expect that to continue into 2024. So we feel good about it.

[Darrin Peller, analyst]

That I guess just my very quick follow-up would be on the corporate payment side. Just to make sure we're clear. The medium-term targets I mean there's obviously a lot of puts and takes on this year on the high single-digit core payments growth. But when we think about the medium term, it's still 10% to 15% if you could just make sure -- reiterate if you still have conviction in that. And then I guess with all these moving parts, it probably is clear that why it would reaccelerate. But what would be your conviction in the driving forces of that back to 10% to 15% again?

[Melissa Smith, executive]

Yes. I would describe those as long-term targets, the 10% to 15%. But as you're going into this year, you're moderating off from a really strong travel growth here. And so that's -- our expectation is that, that's going to decline in the course of the year. We'll see how that actually plays out, but that's the assumption we have in our guidance. We also are seeing some really good ramp that's happening outside of travel. So you ask about confidence on our ability to hit our long-term growth targets. It's because of the ramp we're seeing outside of travel as well.

Our next question comes from the line of Sanjay Sakhrani with KBW.

[Sanjay Sakhrani, analyst]

I guess first question just on the guide and sort of the macro forecast. It sounds like you guys are being pretty conservative with the GDP outlook. I'm just curious if there's something you're seeing or is that just being intentionally conservative. Just kind of get a little color there.

[Jagtar Narula, executive]

Yes, Sanjay. So what we do during our planning process is we go out to a pretty large bank group economists at Moody's, S&P, the Fed, other institutions that are that are publishing GDP forecast. And when we could average that up against the 20 institutions that we survey, we see about 1.5% is the average. And so we use that in our planning process. We're not trying to kind of make up what we think GDP is going to we really use it based upon what external parties are saying.

[Sanjay Sakhrani, analyst]

And I guess like what you've seen year-to-date with the weather and stuff, I mean, there's nothing that has led you to be more cautious or anything like that?

[Melissa Smith, executive]

No. And from a trend perspective, there's nothing that we've seen. Same-store sales was down in the fourth quarter in North American fleet, which was included in our numbers by 1.5% over the road has been down throughout the course of the year for 2%. And we just are assuming that the over-the-road market is stable. Our numbers as opposed to seeing a significant rebound. So there's a little bit -- I'd say just a little bit of weakness that are coming through. Some of that we think is weather-related. And we'll know more as you see that play out in the first quarter. But anything that we've seen coming through January.

[Jagtar Narula, executive]

Has been in line with expectations in January.

[Melissa Smith, executive]

Yes.

[Sanjay Sakhrani, analyst]

Got it. And then Melissa, you have talked about the benefit of the annualized benefit of the acquisitions. Maybe you could just talk a little bit about the contribution. And then Payzer, I know it wasn't really added to earnings, but maybe sort of what you guys expect in 2024.

[Melissa Smith, executive]

Payzer itself, we are expecting that to continue to grow at the rate it was. So plus 20% in our guidance in 2024, when you accumulate both the acquisitions, it's in our long-term target at 2% to 3% of overall revenue growth, and it really is not material to earnings. Because Payzer came in, we talked about the fact that was dilutive last year that they're moving it to accretion during the course of the year. didn't really impact from an earnings perspective, but it's giving us a two different lift in revenue.

[Operator]

Our next question comes from the line of Ramsey El-Assal with Barclays.

[Ramsey El-Assal, analyst]

I wanted to ask in the nontravel part of corporate payments. How much exposure you have to political ad spending in 2024? recall that, that was a vertical that you were exposed to, I believe. And I'm just curious how much you think that's going to benefit you this year, given it wasn't really in numbers last year as there wasn't a lot of political spending?

[Melissa Smith, executive]

It's actually really good memory. It was part of our model many years ago. It is actually not part of our model now. And so we really don't expect or not planning to have any meaningful impact based on the election.

[Ramsey El-Assal, analyst]

Okay. And then I also wanted to ask about the strong sales momentum in mobility, and just ask you to kind of break that down a little bit for us in terms of what's driving that. It seems like you're having some success in the marketplace is that sales investment incentive structures? Is it other factors that might be helping you to convert some customers out there in the marketplace?

[Melissa Smith, executive]

Yes. It's been a long legacy of ours to deliver from a sales perspective and across the business. But in mobility, we've had a multichannel approach where we're pulling in business for our partners with which there's over 20 branded relationships, the names that you would recognize. And then on top of that, under direct channels. What I would say for the course of the last couple of years, there's been a significant conversion where that business is coming from, where is much more is coming through the business digitally. And so a lot of the work and change in work has come from increasing our marketing effort, changing ways that the business comes through, so it's coming through more fluidly through our digital channels. And so we've seen the benefit of that with the fact that we are actually bringing in order with left sales costs associated with that. And so when I talk about the success of that, I feel like we've done a great job pivoting and marketing in a different way into that part of the business. And we changed our credit practices in the course of the last year. And so that really required us to reboot applications volume activity in the course of the year. And you can see the benefit of that has come through really every quarter. The improved applications that are coming, some of the smaller accounts are getting -- have grown the size of the customers that are coming in are larger than they were a year ago, and therefore, we believe more profitable. And so we -- I feel good about not just the numbers that we're bringing from a sales perspective, but the quality of what we're bringing in.

[Operator]

Our next question comes from the line of Andrew Jeffrey with Truist Securities.

[Andrew Jeffrey, analyst]

I appreciate you taking the questions. Lisa, I'm curious about your comments about card attach in in travel. And I wonder if you could talk about different use cases. I know the merchant model is one of the drivers, but are there other use cases to which you're referring, that's driving attach? And then I wonder if you can expand a little bit in the same vein, just in corporate, the -- you saw good volume growth and a little bit slower revenue growth this quarter ,a little better than 3Q and just sort of the dynamics of card acceptance and attach in that segment would be really helpful.

[Melissa Smith, executive]

Yes. And your last point better than 2Q and 3Q and you can look sequentially, it's improved each quarter. Going back to the travel question. There's two real primary drivers of the volume growth that we're seeing within travel that we were trying to highlight. One is the fact that we've been working with our partners to shift volume to us in most of our partners or many of them use multiple providers. And so we've been working with them to make sure that we're set up in a way that creates the value to them to move volume to us. And then the second part of that is the migration what you're talking about, which is largely this migration to the merchant model where the virtual card transaction actually is in play. Otherwise, people are paying the hotel directly. And we have benefited to both of those things, and you can see that coming through the 40% increase in travel spend we saw in the fourth quarter.

[Jagtar Narula, executive]

And then on the nontravel side, I would say, as I mentioned earlier, we saw really good results out of our direct investments. So we did get good volume growth overall. A lot of that volume growth was in the partner channel, and that's just our partner is performing well. But we had started making investments in the direct business, late '22 accelerating into '23. And so we expected to start to see the impact of that as we go through '23. And so in the fourth quarter, we did what we expected would start to see impact. And the rate is a little higher or a bit higher on the direct channel. So that drove, like I said, half the revenue benefit in the fourth quarter in the nontravel side. So it's an area that we continue to invest in, we continue to watch, and we continue to be excited about.

[Operator]

Our next question comes from the line of Dave Koning with Baird.

[David Koning, analyst]

Yes. Good job. On the mobility segment guidance, the high end of the range, I guess, two questions, first of all, how do you kind of see that through the year? I assume Q1 starts a little lower. And then secondly, gallons and transactions have been pretty flat the last few quarters. Is that what's going to accelerate? Or is it something else around yield or account fees or finance revenue?

[Jagtar Narula, executive]

Yes. So let me i[indiscernible] about how they go through the year. So you're absolutely right. We expect that to accelerate over the course of the year. I'd say there's a few things driving the mobility segment. The first is the acquisition of Payzer, and I think Melissa mentioned this earlier, that adds about 2 points of the growth. right? If you back off of Payzer, there's a couple of things that we saw in '23 that we think we start to lap in '24. So the first thing we saw was lower late fees that was roughly 3 percent-ish drag on '23 revenue in the mobility segment. And that was the result of the new -- the tighter credit that we had in 2023. Obviously, as I said in my prepared remarks, we think that was decision because the credit benefit outweighed the drag in late fees. But as we get through '24, we're not further tightening credit policy, so we'll start to lap that, and that won't be a drag. That also same thing also impacted gallons in 2023 because we were tightened credit for certain customers, combined with weakness in the OTR segment. we saw some low gallon volume growth in 2023. Again, that's something we will start to lap those items in '24, Hence, our assumption of acceleration in '24 on both gallons and revenue.

[David Koning, analyst]

Got you. That was very helpful. And then secondly, it looks like there's no buybacks in the guidance just based on how you kind of guided Q1 and then full year being higher. What's the plan for use of cash this year? I mean, is it just to pay down debt given the higher rates now without the swaps?

[Melissa Smith, executive]

So our intention is to use the cash both for acquisitions and for share buyback. And obviously, like we've been buying back stock. We bought back 1.7 million shares last year. And so we have like a strong emphasis that we believe that our stock is still at a good value, and we'll continue to place emphasis there. That being said, we will also, at the same time, look at pipelines for M&A transactions and evaluate that as another use of capital.

[David Koning, analyst]

Great. Well, it's great to see it's not in guidance. It's kind of an upside driver.

[Operator]

Our next question comes from the line of Trevor Williams with Jefferies.

[Trevor Williams, analyst]

Great. I wanted to ask on benefits. Melissa, maybe if you could revisit the longer-term growth algorithm in the 15% to 20% targets you guys had laid out earlier in 2023. And account growth has slowed the last couple of quarters. I'm curious if you think high single-digit account growth is kind of the right normalized level that we should be thinking about going forward? And just if that's the case, how we bridge from that to the 15%-plus longer-term target?

[Melissa Smith, executive]

Sure. If you look at Devenir's last report, they've got long-term HSA growth at 10%. So still in the double digits. I think that there are also cycles for that. What we found going through this most recent open enrollment season is we had more non decisions than we did the year before, which was like a really strong sales cycle. And so I think they're going to have anomalies within each of the sales cycles. But over the long term, we do feel good about our ability to grow accounts. And then on top of that, what we're seeing now, which we think will continue, is that the custodial asset base will outpace the growth of the accounts. And that is a meaningful shift. As we've added that capability, the revenue per account has gone up pretty significantly. And so the ability to create a new source of revenue that is a multiplier effect to the base of our portfolio. And then on top of that, we are continuing to cross-sell into that customer base, the products that we've added, which are COBRA product, our benefit registration product, the most recently, the census capability. And so when you aggregate all those pieces and then the expectations that health care costs are going to go up and so that spend balances are going to increase, meaning the actual purchase volume will also be higher than accounts. Those were what drove our expectations as the long-term growth rates of this segment, which is something that we'll keep talking about in the course of the year. Obviously, we're guiding below that in 2024 based on what we're seeing right now. We do feel very good growth rates, though, competitively that we are winning our fair share in the marketplace.

[Trevor Williams, analyst]

That's helpful. And for Jagtar, the payment processing rate in fuel for the year, that was up about 14 basis points, and you've referenced the last couple of quarters, the benefit that you've gotten from the escalators tied to interest rates. Could you give us a sense just for how much of a tailwind the interest rate escalators were for the year and with what you're expecting in terms of interest rates for 2024? Just how much of that tailwind you would expect to reverse this year?

[Jagtar Narula, executive]

Yes. So I would say the increase in the interchange rate mobility was a mix between the tailwind of interest rates and also price negotiations we've had with merchant vendors where we've been able to improve price and Melissa talked about pricing optimization earlier. So it's a combination of the two. We expect next year, I'd mentioned the assumptions around 5 quarter point rate reduction. So we expect that to be a slight drag on mobility revenue next year. The way I think about it is 100 basis point movement in rates on an annualized basis is about a $50 million impact on mobility revenue. So that's the way I would model it.

[Operator]

Our next question comes from the line of James Faucette with Morgan Stanley.

[James Faucette, analyst]

Just a couple of follow-up questions for me. First, within mobility and the Fleet business, can you talk about what you're seeing on the same-store basis? And what are the drivers there? And can you give us any color on how -- what bearing you might be seeing across customer sets?

[Melissa Smith, executive]

In the fourth quarter numbers, we saw a negative 1.5% same-store sales in North American fleet and a negative 2% over the road on same-store sales. I said this earlier, but one of the things that we're curious about is whether weather had an impact on that. So we'll see how that plays out in the course of this year. Because it was pretty broad brush. It wasn't -- it was -- if you look across the various SICs, it was pretty much the same across every category, which is unusual. And so from our perspective, we think that was probably more weather related. On the over-the-road side and that we continue to hear from our customers the same things have stabilized. They're coming off a better comp. But we're -- they're not anticipating to seeing a big rebound anytime soon, and that's what we factored into our guidance, just this idea of stability.

[James Faucette, analyst]

Yes. Got it. Makes sense. And then just -- like I know it's small and super early, but just since you launched the venture capital fund, I always think that, that's kind of an interesting opportunity and exercise for WEX. Just any early views or learnings as you start to go down that and the types of potential investments that you're looking at?

[Melissa Smith, executive]

For us to reinforce the idea that was the right path. We've got a lot of early-stage companies that are out there, many of them are pre-revenue. And it's given us an ability to learn in that marketplace without putting a lot of capital into it. And so far, I would say what we have made just a few investments. The companies that we've invested in are still out there in the marketplace, proving out their value propositions. They all have interesting ones that are solving very specific niches in the marketplace. And what we're able to do is then expose that to our customers and get a sense of what's going to get traction, what isn't. And so our objective is to have a open network where we're exposing through APIs, many different types of functionality, some of which will own some of which we're partnering with others on. And these investments allow us an avenue to do that.

Yes. The place we're talking about pricing, just really specific is in our mobility segment. It's the place that we continue to experiment within that customer segment or different ways of packaging and pricing to those customers. And also, you've seen the benefit of renegotiation of merchant rates. And so as we've gone into contract renewals with our merchants, we've been able to, on average, negotiate up on rates. And as Jagtar said, we've also got the benefit of interest rate escalators that were in there as well. And so when we talk about pricing, it's this idea that we think that we'll continue to get benefit on the merchant rates. We also will continue to experiment with different ways of pricing into our existing customer base. and we'll get a lift to that course of the year.

[Jagtar Narula, executive]

Yes. And I would add. So I'm hesitant to give out a specific dollar amount related to pricing impact. But what I would say from a dollars perspective, we expect a similar impact in '24 that we saw in '23 from pricing. And most -- a lot of voice is -- almost all of which is already baked in because we've completed those negotiations and price changes.

[Operator]
