To ask a question, you may press star then one on your touch tone phone. To withdraw from the question queue, please press star then two. Please note this event is being recorded. I would now like to turn the conference over to Aaron Hoffman, Senior Vice President, Investor Relations. Please go ahead.
Good morning, everyone, and thank you for attending today. Joining me on the call are Chris Cartwright, President and Chief Executive Officer, and Todd Cello, Executive Vice President and Chief Financial Officer. We posted our earnings release and slides to accompany this call on the TransUnion Investor Relations website this morning. Our earnings release and the accompanying slides include various schedules which contain more detailed information about revenue, operating expenses, and other items, as well as certain non-GAAP disclosures and financial measures, along with the corresponding reconciliations of these non-GAAP financial measures to their most directly comparable GAAP measures. Today's call will be recorded and a replay will be available on our website. We will also be making statements during this call that are forward-looking. These statements are based on current expectations and assumptions and are subject to risks and uncertainties.
Actual results could differ materially from those described in the forward-looking statements because of factors discussed in today's earnings release, in the comments made during this conference call, and in our most recent Form 10-K, Forms 10-Q, and other reports and filings with the SEC. We do not undertake any duty to update any forward-looking statement. With that, let me turn the time over to Chris.
Thank you, Aaron. Let me add my welcome and share our agenda for the call this morning. First, I'll discuss the macroeconomic conditions in TransUnion's markets around the world. I'll provide an overview of our solid in-range fourth quarter revenue and adjusted EBITDA. I'll also review the promising progress with our recent acquisitions to accelerate revenue growth, achieve targeted savings, and leverage their technologies across the enterprise. Finally, Todd will detail our fourth quarter results along with our first quarter and full year guidance. Beginning with slide 4, inflation in our developed markets in around the world remained elevated throughout the year, and central banks raised interest rates to slow consumer demand and return to long-term inflation targets. Economic growth slowed as a result. However, thus far, developing economies have been less impacted by these factors.
Activity in our international emerging markets of India, Asia Pacific, South Africa, and Latam have remained strong. Over the course of 2022 in the U.S., the U.K., and Canada, higher inflation and interest rates have pressured consumers and sapped economic growth. In each succeeding quarter in these markets, growth slowed and consumers became more cautious given the impact of inflation on their spending power. In the U.S., consumers are still healthy overall due to high employment and low debt-to-income levels compared to before the pandemic. However, consumer savings have declined, delinquencies have risen, and spending has fallen, especially for lower income and subprime consumers.
Many of our large lending customers have confirmed this perspective, and while their financials are still strong and consumer demand for credit is healthy, they too are cautious that their markets might slow further and as a result have tightened lending standards, reduced originations and increased loss reserves. Despite these headwinds, TransUnion grew revenue at high single digits organically in 2022, excluding the impact of mortgage in the U.S., and improved its margins because of revenue flow- through improved cost management while also maintaining our transformational investments. Our forecast for 2023 assumes a continuation of the challenging market conditions from the second half of 2022 and little recovery over the year, although our growth rates will improve in the latter half due to easier comparisons.
Despite these more difficult conditions, we expect to grow revenue in the low to mid single digits in organic constant currency terms and expand adjusted EBITDA margins. Our investments in recent years have diversified our business along geographic, vertical, and product dimensions. This expansion is enabling our ongoing growth even as U.S. lending markets slow. Attractive growth continues across our international markets, U.S. emerging verticals and our three recent acquisitions Neustar, Sontiq, and Argus. Our solutions enable growth and effectiveness in all market conditions, and we believe we'll be able to grow organically in 23 even should the U.S. economy dip into recession. Todd will walk you through the details later of our full year guidance and expectations for each of our markets and verticals. In the fourth quarter, our business delivered good results despite challenging macro conditions and softening lending volumes in some markets.
Our financial services vertical grew in the U.S., excluding the impact of mortgage. Auto lending increased due to easing of supply chain constraints, credit cards continued the strong originations seen for over a year. Although consumer lending did decline slightly, it faced very challenging comparisons over breakout growth from a year ago. U.S. emerging verticals resumed attractive growth after an unusually slow third quarter due to anomalous and non-recurring factors. Tenant and employment screening volumes improved after stalling last quarter, media revenues resumed growth after implementing systems improvements. Also, insurance carriers increased marketing as they began to receive rate increase approvals from state commissioners. Our international division again grew revenue by double digits organically in constant currency, led by 33% revenue growth in India, 26% growth in Asia Pacific, 16% growth in Africa, and 12% growth in Latin America.
Canada grew 8% and the U.K. was up 3% excluding one-time business from the year ago quarter. Our international sales teams continued to attain record bookings through thematic selling, leveraging innovation, and expanding into attractive adjacencies. Importantly, we expanded our adjusted EBITDA margin by about 110 basis points organically while maintaining our heightened investment levels in transformational programs. The growth and momentum from our acquisitions also increased in the fourth quarter, especially at Neustar, where we made meaningful progress integrating our acquisitions and further developing our global enablement platforms. I'll provide further details on this in a moment. Finally, we successfully completed the divestment of several non-core assets acquired as part of the Argus transaction, further lowering the purchase multiple and enabling strong returns.
Our progress in the fourth quarter across these many areas illustrates the overall strength of our execution last year. We delivered organic constant currency revenue growth of 7%, excluding mortgage, highlighted by the strength of our international emerging markets and strong growth in financial services in key emerging verticals. We also delivered attractive adjusted EBITDA margins due to revenue flow-through, effective cost management, which we began late in the second quarter when we recognized slowing conditions, and acquisition profitability improvements from growth and cost synergies. As a result, our cash flow remained strong and we prepaid roughly $600 million in debt throughout the year. On to slide 7. 2022 was a strong year for the growth and integration of our recent acquisition.
These businesses are delivering financially and strategically, their strong results, along with positive customer feedback, confirm the rationale for each deal and the benefits of combining them with TransUnion's capabilities. Neustar led the way by posting 8% organic growth in the quarter over difficult comparisons from the last year, with 9% growth in marketing. For the full year, Neustar revenue grew 6% at the high end of our revised guide. Adjusted EBITDA margin was 28% in the quarter and 26.5% for the full year, 150 basis points ahead of our guidance at the beginning of 2022. The strong fourth quarter for Neustar sets the stage for another significant step-up in performance in 2023, which I'll discuss in a moment.
TransUnion and Neustar Marketing Solutions together produced roughly $300 million in revenue last year, growing double digits organically despite softer advertising market conditions and a step back in e-commerce activity. Marketing interest remains strong for these targeting and effectiveness solutions, as shown by our strong bookings last year and the growing pipeline of opportunities. Significant wins in 2022 include an eight-figure multi-year agreement with a performance-based marketing firm to become the primary provider of credit-informed marketing, a deal with the card division of a large consumer bank for multi-touch attribution to help them optimize their spend across all addressable channels, and a partnership with a major online streaming platform to optimize the monetization of their inventory using Neustar and TransUnion solutions. We also completed the onboarding of the Fortune 10 company we announced last year and are benefiting from the ramp in its revenues.
The fourth quarter also concluded a strong year of product integration as we continue to combine our data, products, and infrastructure to create market-leading capabilities. Key accomplishments include integrating TransUnion's relevant data into Neustar's OneID platform to enhance identity resolution, including our header file, phone and email addresses, device IDs, and audience targeting data, among others. Commencing the replacement of all identity graphs across our non-FCRA products with our new Enterprise Graph on OneID. Beginning the consolidation of multiple audience targeting products on our TruAudience platform. We also closed eight data centers and completed the migration of OneID to the Google Cloud, saving almost $20 million a year in recurring costs.
Finally, we've integrated our identity resolution services into Snowflake's Media Data Cloud to enable their customers to enrich their information using our services, which utilize privacy-protected resolution capabilities fueled by offline and online identity intelligence from within Snowflake's environment. This partnership continues our success in penetrating cloud-based data management environments using our identity services through partnerships including Amazon, Google, and many other clean room and customer data platform providers. Now on to communications. Our innovative family of Trusted Call Solutions, which includes Branded Call Display and Caller Name Optimization, continues to provide differentiated growth. During 2022, we strengthened our position through several new partnerships that now provide TransUnion with the largest footprint of wireless and wireline devices in the U.S.
Since the inception four years ago, Trusted Call Solutions has grown to more than $50 million of revenue. We estimate that we've tapped less than 5% of the U.S. market. This enormous potential, combined with our sales reach into large enterprises and our international footprint, positions us for significant growth. Our sales forces are now fully integrated and trained to cross-sell Trusted Call Solutions across our many verticals, which has led to wins in insurance, collections, and financial services, and a strong pipeline entering the year. Given Neustar's revenue momentum, we have confidence in a high single-digit organic revenue guide for 2023 based on strong prior year sales and the +80% recurring nature of Neustar's revenue.
We also expect adjusted EBITDA margin to expand from 26.5% to 32% in year, positioning us to reach roughly 40% margins by 2025 as we fully realize cost synergies of at least $80 million now, increased from our prior guidance of $70 million. Now, Sontiq revenue again grew in high single digits in Q4 and for the full year on the strength of new subscription sales of integrated offerings with TU's consumer direct business. Now, this combination led to an eight-figure competitive win that should fully monetize in 2023. Also, adjusted EBITDA margins in 2022 were 32%, or 38% excluding integration costs. We also have a growing pipeline of opportunities for identity protection services across our financial verticals, which should ensure that we reach our targets for Sontiq.
In the quarter, Argus' revenues declined 3% as we lapped strong comparisons for spend-informed analytics and portfolio management services resulting from a surge in credit card marketing beginning in late 2021. For the full year of 2022, Argus grew revenues in the low single digits and adjusted EBITDA margin was 21% or 29% excluding integration costs. We also divested G2, LCI, and Fintellix, non-core businesses bought last year as part of the Verisk Financial Services acquisition for $176 million in consideration. Divestitures of the non-core assets from this transaction, along with expected cost and revenue synergies, should comfortably lower the EBITDA multiple of this deal to high single digits. We continue to see renewed interest in the market for innovations using Argus data and insights.
Revitalizing the delivery of Argus data on TU's analytics platforms and infusing our market insights will be the key to increasing revenue growth in the future. On our March 2022 Investor Day, we introduced our global operating model and our four enablement platforms: technology, data and analytics, solutions, and operations. During the year, we made considerable progress developing each. Our technology evolution will increase our development capacity and our innovation speed. With Project Rise, we're migrating to a hybrid multi-cloud environment on a common set of enterprise software services and eliminating redundant applications. In 2022, we moved 30 applications to our secure cloud environment and eliminated eight data centers. This year, we will scale our migrations and move over 100 applications to our two clouds and shutter portions of our legacy infrastructure. By the Project end, two-thirds of our applications will run in the public cloud.
With the acquisition of Neustar and its OneID platform, we formed a data and analytics function to create a common foundation for our data management, governance, decisioning, and analytics tools globally. This team set up a security, privacy, and compliance guardrails around the world for all data assets and has developed a central identity resolution capability. The D&A team has also enhanced our innovation lab model development capability using the OneID platform and extended the service from the U.S. into the U.K. to help lenders of all types enhance underwriting and compliance. We held a record number of innovation labs in 2022, we expect to increase this number in 2023 as we roll this capacity out globally. In solutions, we're integrating Neustar's fraud capabilities into our next-generation modular and flexible platform. We also rolled out U.S. products like ShareAble into international markets.
In India, we've launched a new solution to support agricultural lending, which accounts for roughly 18% of lending in that market. TU CIBIL released a credit and farm report in October, which digitizes a traditional lending process by combining credit data with satellite imagery, land records, and crop intelligence. This powerful tool enables better decisions on agricultural loans and faster disbursements of funds to farmers, supporting our goal of using information for good and also promoting financial inclusion. Finally, our operations team implemented a common sales service and order management system globally based on standardized and automated processes. In 2023, we'll continue to refine the user experience, workflow automation, and analytics and reporting in the system to drive efficiency.
We also more than doubled the employees in our Global Capability Centers from about 1,800 to roughly 4,000 through acquisitions and also internal hiring, including opening a new center in Costa Rica. We set up our GCCs in multiple locations around the globe to prevent a single point of failure, to minimize country risk, and to provide services around the clock. These centers offer broad capabilities and access to immense pools of talent, along with proximity to markets with rapid growth potential. That wraps up my comments on our market conditions, fourth quarter performance, and the meaningful accomplishments in 2022. Todd will provide you with further details on our fourth quarter financial results, our first quarter in full year 2023 outlook. Over to Todd.
Thanks, Chris. Let me add my welcome to everyone. I'll start off with our consolidated financial results. fourth quarter consolidated revenue increased 14% on a reported and 17% on a constant currency basis. Neustar, Sontiq, and Argus added about 19 points to inorganic revenue, and I'll remind you that both Neustar and Sontiq contributed to organic growth beginning in the month of December. Organic constant currency revenue declined 2%. Our business grew 2% on an organic constant currency basis, excluding mortgage from both the fourth quarter of 2021 and 2022. For full year 2022, mortgage represented about 6.5% or about $240 million of our total revenue. Adjusted EBITDA increased 14% on a reported and 17% on a constant currency basis.
Our adjusted EBITDA margin was 35.6%, down 10 basis points compared to the year ago quarter. Excluding Neustar and Sontiq in October and November, and Argus from the full quarter, the organic constant currency margin would have been 36.8%, up about 110 basis points compared to the year ago fourth quarter. Fourth quarter adjusted diluted EPS declined 4%, with adjusted EBITDA growth offset by higher interest expense and a higher than expected full year adjusted tax rate of 22.4% compared to our 22% guide.
Our full year adjusted tax rate came in almost a half a point higher than we anticipated, primarily due to the completion of our analysis of certain tax implications of our recent acquisitions and the final determination of the impact of a change in U.S. tax law regarding the requirement to capitalize and amortize R&D expenses. The result was a slightly higher full year adjusted tax rate with a cumulative catch-up recorded in the fourth quarter. I point out that our multi-year proactive tax strategy has resulted in an attractive adjusted tax rate, and we continue to look at future opportunities to further ensure our tax structure is operating efficiently. Now looking at our segment financial performance for the fourth quarter, U.S. Markets revenue was up 23% compared to the year ago quarter. Organic revenue declined 4%, but was up 3% excluding mortgage.
Adjusted EBITDA for U.S. Markets increased 21% on an as-reported basis and declined 3% on an organic basis. The adjusted EBITDA margin increased by 50 basis points on an organic basis. Diving into the results by vertical, please note that we are now reporting Neustar's financial results to the appropriate verticals. To help you with your modeling, we provided a recast of our 2022 results yesterday in an 8-K filing. The majority of the revenue remained within emerging verticals. For the full year 2022, Neustar contributed $120 million of revenue that is now part of financial services. All the results we provide today will be on the recast basis. Financial services revenue grew 6% as reported and was down 10% organically, excluding Argus for the full quarter and Neustar from October and November.
Excluding mortgage, organic constant currency revenue growth was 2%, despite comparing to a 27% growth rate in the fourth quarter of 2021, implying a 15% two-year growth CAGR. Looking at the individual end markets, consumer lending remained in relatively good shape. Lenders continued to market and originate even as we saw some modest targeted pullback. In the quarter, revenue declined 4% against 40% growth in the year ago quarter. Our customers continued to confirm that investors are in market but focused increasingly on lower risk consumers and the lenders with the best recent track records. We've also seen balance sheet lenders using this as an opportunity to gain share.
As we've done in past soft markets, we will use this as an opportunity to enhance our already strong position with fintech lenders, leveraging our expanded, impactful set of solutions to help them understand their customers and make effective decisions through the cycle. Understanding that fintech is of particular interest to investors, let me put our current strong position in historical context. In 2022, total fintech revenue was about $175 million, up 15% over 2021, which had been the largest year ever. The prior largest year was just over $100 million of revenue in 2019. Today we have a business that is almost 75% larger than just three years ago, driven not just by growing volumes, but also by share gains and innovation-led growth.
We continue to believe that over the long term, we can continue this very strong growth trajectory as we win new business and expand our share of wallet with existing accounts on the strength of our innovation and the capabilities acquired with Neustar and Argus. Our credit card business had another solid quarter, growing 5% after nearly 30% growth in the year ago quarter. We have seen consistently strong origination activity for more than a year. To date, we've observed very limited pullback in customer marketing activity as most lenders are still in strong positions to find opportunities across that spectrum and gain top-of-wallet position with the generally healthy consumer Chris described. Our auto business delivered 14% growth in the quarter. We saw new vehicle sales tick up for the first time this year, days inventory on the dealer lot building, used vehicle prices coming down.
These factors set the stage for an industry expectation of a 7% increase in new car production in 2023. We're already experiencing solid market trends in the early weeks of the first quarter. Used car sales remain somewhat sluggish as higher interest rates tend to have a more pronounced impact in this part of the market. We continue to outperform the underlying market based on wins from the strength of CreditVision Link, which lenders are using to better assess risk in the current environment, ongoing success with our digital pre-qualification solutions, and renewals with key Neustar auto customers. For mortgage, revenue is down 44% in the quarter and down more than 30% for the full year. At this point, refinancing activity is almost non-existent, while the purchase market has maintained modest origination levels.
As we've expected, HELOC activity has picked up as consumers use this as an efficient way to realize short-term liquidity. For 2023, we expect the inquiry market to be down mid-20s% and our revenue to increase mid-single-digit%. We expect to outperform the market on the strength of HELOC activity, increased demand from the targeted marketing solutions lenders are turning to in a very tight market, and price increases. Let me now turn to our emerging verticals, which grew 47% on a reported basis and 4% organically, excluding the revenue associated with Neustar in October and November. Insurance delivered another good quarter, growing despite the slowdown in marketing activity driven by higher repair and replacement costs and the extended time required for carriers to affect rate increases at the state level.
Our attractive portfolio of innovative solutions in commercial and life applications, as well as driver risk in our traditional private auto market, have helped offset some of the macro issues in the market. Importantly, we've seen a steady stream of rate approvals on a state-by-state basis that should result in increased marketing activity and consumer shopping, both of which lead to revenue opportunities for TransUnion. Tenant and employment screening growth improved sequentially as a result of early signs of a recovery in the tenant market, with month-over-month declines in rental rates and increases in move rates. This growth was somewhat offset by a softer employment screening market as employers take a more cautious approach to hiring. Our media vertical grew again in the quarter despite some modest market softness driven by multiple years of new business wins and accelerating usage levels with existing accounts.
We continue to sign new deals and expect further growth in this area from the integrated go-to-market and solution offerings Chris discussed. Consumer Interactive revenue, which includes Sontiq, declined 2% on a reported basis and declined 13% organically. As we discussed in the fourth quarter of 2021, our business benefited from significant breach remediation work last year. Excluding that large one-time business, organic revenue would have declined 5%. Adjusted EBITDA was up 3% and down 5% organically. Similar to the previous two quarters, several factors adversely impacted revenue. Moderating consumer demand for paid credit-related solutions across both the indirect and direct channels, challenging multi-year comparisons to exceptionally strong performances in the direct channel in both 2020 and 2021, and the comparison to one-time breach-related business.
Our continued strength in identity protection, an area where our Sontiq acquisition enhances our capabilities, partially offsets these factors. To update you on the direct indirect revenue split with the inclusion of Sontiq, about 2/3 of revenue is indirect and 1/3 is direct. For my comments on International, all comparisons will be in constant currency. For the total segment, revenue grew 12%, with four of our six reported markets growing by double digits. Adjusted EBITDA for International increased 15% as a result of our strong revenue growth. Let's dig into the specifics for each region. In the U.K., revenue declined 5%. Excluding the revenue related to one-time contracts, including with the U.K. government, we would have grown about 3% in the quarter despite a challenging macro environment. We saw a softness with many lenders in the fourth quarter, but have experienced improved trends in January.
At the same time, we had a strong quarter in our gaming vertical, driven by heightened activity levels around the World Cup. Our insurance vertical also delivered good growth as more customers are using TrueVision trended credit data for pricing. Our consumer business has gained share due to the CreditView platform strength, and we won a large breach contract in large part because of Sontiq and its unique remediation capabilities. Finally, a few weeks ago, we announced an investment in Bud Financial, one of the leading open banking providers in the U.K., to help drive innovation and growth in the market and support financial inclusion. Our Canadian business grew 8% in the fourth quarter, reflecting growth across the portfolio.
Similar to last quarter, the macroeconomic indicators remained soft, yet our business continued to grow as we won material new business ranging from large banks to fintech entrants. These new wins are still ramping up, and we expect to realize the full financial benefit in late 2023. In India, we grew 33%, reflecting strong market trends and generally healthy consumers. The diversity of our portfolio remains a real strength in India. We saw meaningful growth in both consumer and commercial credit markets, as well as from fraud, employment screening, and direct-to-consumer offerings. In Latin America, revenue was up 12%, with broad-based growth across our markets, including another quarter of growth over 20% for our largest market, Colombia. While macro conditions have generally softened in the region, our teams continued to win new business in financial services, particularly with fintechs and neobanks, insurance, government, and telcos.
We also continued to see strong adoption of CreditVision and our fraud solutions. In Asia Pacific, we grew 26% from continued good performance in Hong Kong, driven by new business with fintech players and exceptional growth in the Philippines, which is now running well ahead of pre-COVID levels as the economy has now fully reemerged from COVID and resumed its strong growth trajectory. Africa increased 16% based on broadly strong performance across the portfolio and the region, despite a challenging environment that includes rolling electrical blackouts and other persistent challenges. In South Africa, our core business continues to grow on the strength of new business wins and meaningful contract renewals. We also benefited from growth in fast-growing verticals like telco and gaming. Outside of South Africa, we continue to see very strong growth in markets like Kenya and Zambia, particularly with micro and fintech lenders.
We ended the quarter with roughly $5.7 billion of debt after prepaying $200 million in the 4th quarter and another $400 million earlier in 2022. That left us with $585 million of cash on the balance sheet, including the receipt of approximately $104 million of the proceeds from the non-core asset divestiture that Chris already covered. We finished the year with a leverage ratio of 3.8 x. Since our IPO in the summer of 2015, we have targeted a leverage ratio of less than 3.5 x. Going forward, we intend to work toward a leverage ratio of less than 3 x, though as in the past, from time to time, our leverage ratio may be higher than our target.
With that said, from this chart you can see that we have to rapidly reduce leverage as a result of our strong adjusted EBITDA growth. What's more, we intend to further prepay debt in 2023 with our excess cash flow. At this time, we have no intention to pursue any large-scale acquisitions, and even smaller bolt-on acquisitions are not currently in our plans. We are focused on absorbing, integrating, and maximizing the growth potential of Neustar, Sontiq, and Argus. We have multiple pieces related to our debt as we enter 2023 that impact our net interest expense. I want to spend a minute on these items. First, our debt stack is unchanged entering 2023, but I wanted to lay out the three tranches with their associated rates on this slide.
We use a layering of swap instruments to hedge about 70% of our debt, which allows us the flexibility to execute meaningful prepayments. At the end of 2022, a swap with $1.4 billion notional value and a rate of 2.7% expired. We replaced that with another, with $1.3 billion notional value, but at a higher rate of 4.4%. You'll note this swap is of relatively short duration, expiring in just two years when we can optimistically contemplate a lower interest rate environment. You can see the impact of higher LIBOR on our unhedged debt and the new higher rate swap on the right-hand side of the slide. The forecast uses the current forward curve. Net interest expense is expected to increase by $55 million.
This is a critical point, this does not include any additional prepayment. This is in line with our long-standing practice of not providing speculative guidance about capital allocation, whether related to acquisitions, prepayments, or any other activity. For your consideration, as a rule of thumb, based on the current forward curve and on an annualized basis, every $100 million of debt prepayment would add about $0.03 per share to adjusted diluted EPS. That brings us to our outlook for the first quarter, where we have the most challenging comparisons of the year. For that reason, we expect our growth rates to improve as the year progresses. In the first quarter, we expect about one point of headwind from FX on revenue and two points of headwind from FX on adjusted EBITDA.
For revenue, we anticipate about a 2-point benefit from the acquisition of Argus. We expect revenue to come in between $908 million - $917 million or down 1% to flat on an as-reported basis and down 1%-2% on an organic constant currency basis. Our revenue guidance includes an approximately 2-point headwind for mortgage, meaning that we expect the remainder of our business will be flat to up 1% on an organic constant currency basis. We expect adjusted EBITDA to be between $310 million - $316 million, a decrease of 6%-7%. We expect adjusted EBITDA margin to be down 190 to 210 basis points as a result of incorporating Argus' relatively lower margins and the impact of revenue mix.
We also expect our adjusted diluted earnings per share to be between $0.73 and $0.75, a range of down 19%-21%, a result of lower adjusted EBITDA and higher interest expense. Turning to the full year, we expect about 1 point of headwind from FX on revenue and 1 point of headwind from FX on adjusted EBITDA. For revenue, we anticipate approximately 1 point of benefit from the acquisition of Argus. We expect revenue to come in between $3.825 billion-$3.885 billion or up 3%-5% on an as-reported basis and an organic constant currency basis, and is the same excluding mortgage as we expect a minimal full-year impact. For our business segments on an organic basis, we U.S. Markets to grow mid-single digits with and without the impact of mortgage.
We anticipate financial services with and without mortgage to be up low single digits. We expect emerging verticals to be up mid-single digits. We anticipate that international will grow high single digits in constant currency terms. We expect Consumer Interactive to decline low single digits on an organic basis. Turning back to the total company outlook, we expect adjusted EBITDA to be between $1.388 billion- $1.421 billion, up 3%-6%. That would result in adjusted EBITDA margin being flat to up 30 basis points, with the significant benefits of the Neustar cost savings partially offset by the inclusion of Argus' relatively lower margins earlier in the year and some revenue mix considerations.
We anticipate adjusted diluted EPS declining 1%-5%, with higher interest expense offsetting adjusted EBITDA growth. To help you complete your modeling of 2023, at this time, we expect our adjusted tax rate to be approximately 23%. Depreciation and amortization is expected to be approximately $525 million. We expect the portion excluding step-up amortization from our 2012 change in control and subsequent acquisitions to be about $225 million. We anticipate net interest expense will be about $280 million for the full year, up significantly, as I showed you earlier, due to rising rates. We expect capital expenditures to come in at about 8% of revenue. Our guidance assumes that current market conditions persist and does not incorporate a U.S. recession.
Nonetheless, in the event that does happen, as we discussed in detail on our second quarter earnings call, we would still expect organic constant currency revenue growth, albeit less than the mid-single digit guide I just provided. This growth is possible because of our expansive, diversified portfolio of relevant solutions and our deep partnerships built on thought leadership and innovation. In this situation, I would expect incremental pressure on adjusted EBITDA and adjusted diluted EPS. In a downturn, we would keep our focus on integrating our recent strategic acquisitions to ensure they deliver against our long-term expectations. We would manage our cost structure to ensure it aligns to the trajectory of revenue growth in order to support our attractive margin structure. I want to wrap up with some extra detail about our expectations for margin expansion in 2023.
The bridge on this slide shows the significant benefit we expect to derive from the Neustar cost-saving program. We also have good margin flow-through from our revenue growth. Partially offsetting these positives are three factors. First, we have the impact of Argus's lower margin for the first three months of the year as the acquisition closed in April of 2022. Second, we have the year-over-year impact of resetting variable compensation costs to target while also allowing for appropriate increases in employee compensation. Finally, we will have higher royalty costs in U.S. Markets. At the same time, we continue to prioritize long-term growth-focused investments in all the areas that Chris discussed this morning. I'm pleased to say that we expect to be able to expand the 2023 margin without taking any significant cost actions, largely because we have a long history of prudent, consistent cost management.
For example, in recent years, we've closed dozens of owned or acquired data centers, we've slowed hiring at times to calibrate to our growth, and we have excellent expense management processes. Beyond that, we continue to reduce our cost structure and derive savings from the good work of our global operations organization, particularly through our Global Capability Centers that Chris highlighted earlier. There are significant future cost benefits from these initiatives. With that said, if the situation deteriorates, we have additional actions like reprioritizing certain investments, managing T&E or other one-time costs that we can execute. We remain focused on maintaining our high-quality workforce in order to fully execute all of the exciting projects that we've described in today's call. I'll now turn the call back to Chris for some final comments.
Thanks, Todd. I want to wrap up today's call by reiterating our commitment to our 2025 targets. Despite the market challenges we're experiencing, we expect to deliver against these targets, although we don't expect that the growth will be linear. Our combination of attractive end markets and geographic footprint, along with differentiated and complementary solutions and a robust innovation pipeline, gives us a line of sight to reaching these goals. Now let me turn it back to Aaron.
Thanks, Chris. That concludes our prepared remarks today. For the Q&A, as always, we ask that you each ask only one question.
All right, gang. Here we go.
So that we can include more participants. Operator, we can begin the Q&A now.
We will now begin the question and answer session. To ask a question, you may press star then one on your touchtone phone. If you are using a speaker phone, please pick up your handset before pressing the keys. To withdraw from the question queue, please press star then two. The first question is from Jeffrey Meuler of Baird. Please go ahead.
Yeah, thank you. The overall revenue guidance looks quite good to me. You gave us a lot of detail on international bookings and emerging markets, conditions, trends in U.S. emerging verticals, Neustar, et cetera. It looks I guess the area that I'm struggling a bit with is it looks like it implies quite an acceleration in U.S. financial markets, including really good growth, probably later in the year. As you mentioned, consumer lending still worsening. You gave us mortgage. Just it sounds like auto is kind of a mixed bag. Can you help us with that piece? Just anything further you can say to give investors confidence in the implied, better trends in U.S. financial markets later in the year.
Hey, Jeff, good morning. It's Todd. Thanks for the question, I think it's a very appropriate place to start this morning. Clearly, when you look at our guide compared to the high end. That we provided of about $3.885 billion. You see where Q1, we're guiding $917 million at the high end. We definitely see a little bit of an uptick, you know, in the revenues from the Q1 levels. Largely, you know, what we're seeing is we feel that we have felt the impact of businesses that are impacted by cyclicality. You know, so for example, the mortgage business, we definitely expect Q1 of 2023 to be a further headwind. As the year progresses, those headwinds will start to find an equilibrium point.
As well as, you know, we're able to take some pricing actions, you know, within mortgage that, you know, as the year goes on, we'll be able to moderate some of the volume decline. Another area to highlight would be our insurance vertical. We saw some unusual factors in the second half of 2022, you know, with the high repair and replacement costs, that our customers were seeing due to supply chain issues and their inability to increase their premiums. As you heard in my prepared remarks already this morning, you know, we've started to see that subside. We're expecting, you know, the insurance business to benefit from insurers being back in market, marketing.
As well as, you know, consumers, shopping, you know, for insurance. Just as a reminder, in our insurance vertical, it's not necessarily linked to car sales. It's more about, you know, the premiums and the impact, you know, to the consumer. That shopping activity, we anticipate to be a driver as consumers are focused on managing their finances in this high inflationary environment. To highlight that too, the reason I just spent as much time as I did on insurance is it's a large vertical, you know, for us now too, based on the recast of the, you know, Neustar financials that, you know, increases the overall size of that business.
Just a couple of other areas, you know, to highlight, our tenant screening business was another one, you know, that we saw some impact in the second half of 2022 as well, that we're starting to see those trends subside as consumers are moving, more apartments are coming online, creating more capacity. As a result of that, you know, rents are coming down. Finally, I think the last one I'd highlight for you, Jeff, would be auto. Our, our auto business, you know, had a good fourth quarter. What we're hearing from many of the auto manufacturers is the supply chain issues are starting to subside, and we're expecting for good growth to come from a new car sales perspective.
Similar to how I talked about insurance, the auto business, you know, will also benefit, you know, as well, you know, from that shopping activity as consumers are looking to advance. The last point I would make on this is that the guidance that, you know, we are assuming, does have a sense of returning back to what I would consider to be normal seasonality, you know, for our business. Where Q1 looks a little bit light, normally you'd see Q2 and Q3 step up, and Q4 maybe be a little bit less. That's also been factored, you know, into our guidance as well.
Yeah. Look, let me just. This is Chris. Since this is the first question, let me just level set here. The basis of our forecast in 2023 is heavily influenced by the challenging market conditions we saw in the fourth quarter, right? While we're not assuming a recession, we're also not assuming any particular recovery. Of course, the growth rates are gonna increase in the back half of the year because the comparisons are gonna ease substantially. As Todd said, you know, the first quarter of the year, because of seasonality, is typically our softest from a revenue standpoint.
It just so happens that this year we're comparing against a very strong 1st quarter in 2022, where the enterprise grew 8%, financial services U.S. grew, I don't know, I think it was in the mid-teens, right? Things were quite robust then. Over the course of 2022, with each passing quarter, we saw softening in our U.S. financial services business and also in the FS businesses in other developed markets. We took that endpoint, which we think is near a bottom, and we extrapolated from that. Now, we've also got some countercyclical benefits. As you saw, our acquisitions are delivering good growth. Neustar, which is a very material chunk of the revenue, we're guiding it to 8%. We exited the year at 8%.
We've got a strong line of sight to that revenue in particular because, as we've said before, it's about 80% recurring, and we had one of our best-selling years ever last year with sales volumes and momentum increasing with each passing quarter, right? We feel like we've got nice momentum in Neustar, which is a big kind of diversifying and countercyclical force at this point.
The next question is from Andrew Steinerman of JP Morgan. Please go ahead.
Hi, Todd. I wanted to look at slide 19. Slide 19, this is the margin slide, and particularly focus on the second red bar, the 45 basis points drag to formulate the 2023 margin. I was hoping you could break down and maybe explain a little bit more the three items that are highlighted there, incentive comp, royalties, and continued investments, you know, recognizing that these three items are offsetting the revenue flow- through.
Yep. Good morning, Andrew. Thanks for the question. Specifically, you know, to the margin, and you see almost a 50 point, you know, decline there. You know, a couple of factors, you know, go into that. You know, first of all, from a compensation perspective, since the second half of last year, TransUnion has been very focused on ensuring that we are making our hiring decisions on important strategic priorities, you know, for us. You know, we continue to fill roles that have that importance for us.
When we look forward, we're very proud of the talented team that we have and, you know, all the work that they accomplished in 2022 with acquisitions and organic initiatives. We felt that it was important to make certain that we're fully recognizing the extraordinary work of our people by providing the compensation, you know, necessary to increase for our merit and promotion pool as well. In addition, we also needed to reset our variable compensation, you know, up, you know, to target levels when you compare to what the payouts were in 2022.
A second thing to cover here would just be, you know, when you think about our volumes, in areas where we are experiencing year-over-year declines in volumes, it's important to note that those declining volumes have a higher margin impact than any type of pass-through pricing markup that we would have on a higher royalty expense, you know, as an example. That's the second important factor to go into there. I think third, you know, in really getting back to the point just on our people, we are continuing to invest in several organic initiatives. We're not sacrificing the long-term growth potential of TransUnion, so we continue to have meaningful investments in initiatives. Chris just covered several of them when he went through the global enablement platforms.
I think those areas really underscore the investments that we make to make certain that TransUnion is a growing and resilient company in the future.
The next question is from Faiza Alwy of Deutsche Bank. Please go ahead.
Yes. Hi, good morning. Thank you. I wanted to pick up on the Neustar commentary. Chris, I think I heard you say that, you know, Neustar revenues are de-risked as we think about 2023. Maybe give us a little bit more perspective around that. How do you need additional sort of big wins as we look at 2023? Perhaps you can give us some commentary around, you know, your perspective on market share in that business. Are some of these new wins related to, you know, market share, or is it more, just more demand for some of the analytics that you're able to now provide? Thanks.
Well, just a quick comment on market share. I think it's difficult for us to comment on our relative market share with regard to Neustar marketing services at this point. Generally, there are more competitors, it's more fragmented. However, in my comments, I did highlight a series of very attractive wins that we scored in this past year, as well as pointing out that that Fortune Top 10 customer has been onboarding, or did, and the revenues are ramping. Look, I think those are good examples of competitive success in the market, and I would expect those to keep coming. Look, thinking about Neustar in a bit more detail. 2021 was a very growthful year for Neustar. They did 8% organic and change. We expected that level of growth going into 2022.
What we were surprised by is that the foundation of growth in 2021 was on an elevated level of e-commerce activity during the pandemic. That dipped, and as a result, midyear, we lowered our guide. We also had some of the normal, I'd say, integration growing pains in the early part of the year. Pretty quickly, all of that started to gel together and we began executing well on the sales side. In each passing quarter over the course of 2022, we sold more, we sold more broadly, and we built really nice momentum going into 2023. Look, the 8% organic growth in the 4th quarter of last year for Neustar, it's important because that comes on top of 9% organic growth, roughly the prior year, right? It's growth over a meaningful comparison. You get to 2023.
You know, de-risking in such a risky environment is always a difficult term to address, and I'm only half kidding here. The fact is, we got great momentum. We had a big year of sales. We've got probably higher line of sight to the 8% growth than we typically would coming into the new year. I feel like we're just getting our rhythm, our mojo, if you will, in terms of cross-selling Neustar products across all of our verticals. That's my two cents about the sales and revenue momentum at Neustar. I'd also point out that the product integration has gone really well. It's going very well in terms of getting TransUnion data into the OneID database that underpins all of Neustar's identity resolution for marketing and fraud. I think we got further faster than we expected.
Now we're taking that, you know, really best-in-class identity, and we're integrating it into all of our products across TransUnion in the U.S. on the non-FCRA side, right? Additionally, now, we've combined all of our audience capabilities, our data, and our platforms. That's coming together. And we achieved a huge step in our integration, right? We closed eight Neustar data centers, and we migrated Neustar's core technology to a new cloud provider, and we've saved or added, you know, $20 million in recurring EBITDA as a result. I feel like we're getting nice traction, but, you know, our plan is to continue our heads down execution on this deal and to build further momentum over the course of the year.
The next question is from Kelsey Zhu of Autonomous. Please go ahead.
Hey, guys. On Consumer Interactive margins due this quarter is partially due to, you know, kind of reduced in investment in advertising. I'm just wondering, should we expect this going forward into 2023? If that's the case, how do you think about the shift in competitive lens in that market as some of your competitors are still continuing to invest in these products?
Yeah, absolutely. Well, look, our consumer direct businesses have faced a series of challenges in the near term. On the indirect side, we needed to lap some contract restructuring, that's the single largest piece. On the direct-to-consumer side also, you know, we realized that some of our marketing wasn't yielding, you know, fully profitable new customers. Also, we wanted to adjust our acquisition workflows to ensure that they were as consumer-friendly as they could possibly be. As a result, we curtailed some of our direct advertising. As a consequence of that, you know, we're winning smaller new classes of customers, if you will, to replace those that attrit over the course of the year. As we look to 2023, though, the foundation is firming considerably, the rate of decline is moderating.
In particular, it moderates quarter by quarter over the course of the year. First, there's Sontiq. Sontiq, we believe, is a long-term, mid-teens grower. Now, last year, we didn't have the benefit of a particularly large breach, but we did accelerate our subscription sales with Sontiq, which is especially valuable because of the high recurring nature. In 2023, Sontiq grows in the mid-teens. On the indirect side, in 2023, we expect to return to mid-single digits growth. In the direct subscriptions to consumers, you know, the first half of the year, we're still declining because of the change in marketing spend and practices. By the second half of the year, in the fourth quarter, in particular, we think we get that behind us. Net-net, those are kind of the dynamics that we see in direct to consumer. Todd, any particular comments on the margin profile go forward?
The first thing I would add on the margin is the Consumer Interactive business always has had an attractive margin profile with an adjusted EBITDA margin, you know, in the upper 40% range, sometimes to 50%. Clearly, that's what we just saw, you know, in the fourth quarter. As we look forward into 2023, you know, Chris just spoke about the direct business, and that's really where the opportunity resides for us to gain efficiencies and optimize our advertising spend. The team's done a great job with that. As a result, you know, we would expect, you know, that the margin for this business would be in the same, you know, range that we've had it historically. In that high 40s to around 50% adjusted EBITDA margin.
The next question is from Toni Kaplan of Morgan Stanley. Please go ahead.
Thanks very much. I noticed that you reiterated the 2025 targets, for adjusted EPS at $6 versus the midpoint of the 2023 guidance, that would imply like a 30% CAGR from 2023 to 2025. Maybe just talk about your confidence in achieving it? Like, I guess clearly you do believe it because you wouldn't have reiterated it. I mean, I just think it sounds sorta high, but I know you can. I know you clearly have reasons as to why you think you can achieve it. Thanks.
Yeah. Thanks for the question, Toni. Well, look, I mean, right now we're facing some challenging market conditions in lending verticals and developed markets, and I think it's easy, you know, perhaps to get a bit more pessimistic about those things. We're talking about we've got three full years to get there. We have a variety of paths to get there. We expect that over this period, that market conditions generally are gonna improve materially. What we've seen is that our business has the potential to grow very rapidly coming out of downturns. We did so, you know, in the 2010 timeframe. We did so again, coming out of the pandemic, where we posted 13% enterprise growth. Again, there are a whole variety of different ways, you know, to get there.
I would point out that, you know, our results in this particular quarter generally are tempered a bit by volumes in fintech. That said, you know, the reason we went into the detail on that space in our commentary is we wanted the market to understand just how growthful that business has been. It's been a nice cherry on top of our overall lending portfolio. We think that the growth, you know, coming from disruption in that space is gonna continue. There's just been a bit of a pause, some caution as players try to understand market conditions and funding sources and the like. I think we're gonna get disproportionate growth out of fintech, out of Neustar, out of the resurgence in emerging verticals. India. India is becoming really material for us.
It grew by a third last year. While we don't have that rate of growth in our plan, we've got a heck of a lot of upside, and we've got a lot of ambitions to expand the number of markets that we play in India. I mean, look, you know, perhaps we revisit this at the end of the year. But at this point, I think, again, we can get there. There are a multitude of different paths. Then I think you were more focused on EPS, and I'm gonna let Todd take that one.
From an EPS point of view, I mean, one of the significant drags, you know, that we've had is the rise in the LIBOR, which our debt is still tied to for the time being. That has a rather significant impact on the EPS. In 2023, we had an impact of about $0.22. Think of it another way. The guide on EPS would be up another 22% if interest rates were like roughly flat, $0.22. You know, if you, if you now think about that over the next three years, if you believe that interest rates decline, TransUnion and the rest of the market would get a natural benefit there. Not an operating factor, but it wasn't an operating factor that, you know, provided this headwind to this as well.
Yeah. Again, just to reiterate, we're very focused on driving as much growth as we can out of the new acquisitions and taking costs out. We were happy to be able to raise the guide to $80 million in synergies from Neustar. Look, you know, I hope a year from now I can come back and share even better news on that front. We're also focused on paying down our debt. We're hoping to get to, you know, 3.5x this year and to take it as low as 3 or below by the end of the following year. That's a lot of interest savings that will benefit our EPS.
Yeah. Just to underscore that point, as we always do, with our guidance, we do not make assumptions on capital allocation decisions with cash that builds. So to that point, if you look at our guide for 2023 and then even out into the future, those pay downs are not incorporated into the overall adjusted diluted EPS as well.
The next question is from Manav Patnaik of Barclays. Please go ahead.
Thank you. Good morning. You know, you had a lot of helpful commentary on how you would perform if there was a recession. I was just wondering, do you guys have, you know, any internal macro calls and probably, you know, the probability of that given all the data that you see? Just tied to that, you know, the guidance overall, you know, would you characterize this as conservative as, you know, TU has been historically, or is it more, you know, I think last year when you came out with guidance, you talked about it being, you know, less conservative, more realistic. Just trying to get a sense of, you know, what this year is set up to be?
Yeah, Manav. You know, good question on, you know, guidance philosophy, but also just kind of some macro insights. What I'll say is, look, I think you should take us at our word on the guidance for 2023, right? We crafted a range after a significant amount of deliberation and thought that we think is reflective of what we can do. Now, you know, if economic conditions were to deviate materially in one direction or another, that's a different factor, right? I mean, we're guiding 3%-5%. I think you should consider 3%-5%. Again, if you look at our fourth quarter, you know, we outlined a guidance range, and we delivered within that guidance range for revenue, for EBITDA, and on an operating basis from EPS.
You know, the small miss on the EPS was due to a tax item, a below-the-line item, right? I think we would just ask investors to take us at our word on the guide. That's where we're targeting. In terms of the macro stuff, look, I can arm your quarterback with you, but the reality is, all of you guys have much smarter and more qualified economists on your staff, so I'm gonna pass on that question.
The last question is from Heather Balsky of Bank of America. Please go ahead.
Hi. Thank you. I'm gonna piggyback off the last question. I won't ask you your macro forecast again, but just in terms of the guidance range, and looking at the low end of the range, I'd be curious to kind of what assumptions are baked into that and how you're thinking about that range. Then later on there, you express confidence in your ability to grow in a recession. How to think of the low end of the range and maybe how that compares to a potential recession scenario?
Yeah, probably the first comment, you know, to make on this question is about diversification across the portfolio and how that dynamic is playing out. You know, without a doubt, our lending lines of business have slowed materially in developed markets because of the effect of inflation first and then rising rates. Potentially, you know, may have slowed, you know, a little extra because it's just uncertainty, right? When there's uncertainty in the market, transaction volumes fall, right? As certainty gets restored around the direction of inflation, around the direction of rates, we could see some improvements. The negative is around the lending volumes. The positive, and again, in the U.S., I'll remind you that the emerging verticals are equal in size to the lending verticals, right? Their growth is increasing.
It increased from 1% in the third quarter, which we said was based on anomalous non-recurring factors, to 4%. We expect it to improve again over the course of 2023. The international businesses, you know, there was less fiscal stimulus. They're not dealing with the same degree of elevated inflation. They continued to roll. That business is $800 million. You know, it's growing. We've targeted to grow in the low double digits. There's a lot of momentum there, right? It's broad-based momentum because our footprint is more skewed. That's gonna be growthful. Direct-to-consumer, because we've had a reset in process over the past 12 months, has been a material drag on our results, and we see that improving substantially over the fourth quarter. Again, I just wanna reiterate in terms of the guidance.
You know, we didn't model in a recession. We didn't model in economic improvement. We took a very challenging macro environment in our fourth quarter, and we largely modeled off of that. Again, there's any number of puts and takes given the multitude of verticals and sub-verticals, but we think it's a prudent guide. It's not overly negative, but it's also not founded on some back-end optimism. Again, the reason organic growth rates increase in the latter half of the year is because our comps are much, much easier, particularly in the fourth quarter.
Excellent. Chris, thank you, and thanks everyone for joining us this morning. There's a lot to digest, I think, in our call. We hope you take the time to do that and, let us know if we can be of assistance as you contemplate, the print today. We hope you have a great day. Thank you.
The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.
