[Suzanne Winter, executive]

Thank you, Jesse, and thank you all for joining the call.

Today, I will provide highlights from our fourth quarter and fiscal 2024, both on our accomplishments and the areas of focus for FY '25 and beyond. I am pleased with our solid performance in the fourth quarter with total company revenue growing 14% year-over-year, reflecting strong operational and commercial execution. This growth was driven by a record number of system shipments within the quarter, representing 20% more than our previous highest shipment milestone.

Momentum going into FY 2025 remains elevated, particularly in the international markets, which represented more than 80% of our revenue for the fiscal year and reflects the strategy we laid out at the beginning of FY '24 of entering emerging markets where patient access to radiation therapy is underpenetrated and where we can become the #1 or #2 player over time. In the quarter, we saw shipments accelerate nicely, both to new customers and by closing open opportunities from the prior period.

We also saw orders growth up 8% versus last year, largely driven by emerging market growth in APAC and Latin America. China was despite remaining headwinds from the anticorruption campaign grew orders by 80% in the quarter year-over-year, driven by pent-up demand for the new Tomo C product, which recently received approval for our precision treatment planning system, making our Tomo C products ready to ship to end customers.

In share in Latin America is a priority for us, and this region saw order growth of more than 400% within the quarter, including a 4-system competitive replacement win in Mexico. Finally, I was very pleased with our global Q4 book-to-bill ratio where even with record revenue shipments was healthy at 1.2%. We believe the book-to-bill metric continues to represent a strong leading indicator for future revenue.

Product revenue contributed materially to the growth within the quarter, up approximately 28% year-over-year, driven by strong demand in China, which grew product revenue by 55% compared to the prior year and the rest of APAC, which grew significantly year-over-year. IMEA, our largest region, delivered 27% year-over-year product revenue growth.

The Japan region was up 1% for the quarter year-over-year, and excluding headwinds from FX, grew product revenue by 13%. Japan is a very strong market for us, and we have put in several initiatives to help mitigate the impact of foreign exchange. We remain the #2 market share player and continue to drive share gain on our path to becoming #1 in this developed market.

Finally, the Americas region, as we had expected, continued to show weakness in Q4 with product revenue down 50% year-over-year, driven by customer delays in installation. We believe we've got the greatest impact in FY '24 and are cautiously optimistic that we will see conditions improve in the U.S. market and show year-over-year growth starting in the second half of FY '25.

Service revenues for the quarter were down slightly due primarily to unfavorable FX in Japan and reduced training and spare parts revenue. However, I am encouraged that recurring service contract revenue was up 4% year-over-year as we start to see the result of our strategy of driving installed base growth by penetrating emerging markets like China where service revenue grew 22% year-over-year.

During the quarter, we received final approval on our Precision Treatment Planning System for China, which was the final step in our [indiscernible] process to the Tomo C platform. As of late fourth quarter, we now have the ability to sell and ship full systems to total fee customers in the Type B segment. As a reminder, with this final approval, we can now fully record margin at time of delivery from our joint venture site in Tianjin to the end customer for all of our total fee shipments in China.

With this approval behind us, we are now able to fully compete in the Type B market, which represents approximately $3 billion in market potential over the next 5 years. Ali will discuss more of the Q4 financials, but I wanted to touch briefly on margins, which continues to be an area of focus, although our overall Q4 adjusted EBITDA margins were within the range we expected, we believe that several factors that negatively impacted margins were transitory in nature and masked underlying productivity improvements we have achieved from our margin expansion initiatives.

From a product perspective, the later timing of the approval of Precision Treatment Planning System in China delayed when we could recognize full margin. With the clearance now behind us, we have begun shipping Tomo C to customers and shipped our first system late in Q4 FY '24 and expect the majority of shipments to accelerate starting in Q2 of FY '25 based on customer readiness. This represents approximately $4 million of margin that was deferred at the end of FY '24. Within service margins were mostly challenged by foreign exchange, which impacted our Japanese business performance materially where we have a large installed base.

In addition, in Q4, we experienced an isolated supplier quality issue that caused a $2.4 million increase in parts consumption costs. We are working closely with the supplier and expect this to be resolved and recover the majority of these costs over the fiscal year. Once adjusted for the China margin deferral and the supplier quality issue, our Q4 gross margins would have been improved versus the same period in the prior year.

Finally, region mix was a headwind to margin as we experienced weakness in the U.S. market, which is a higher-margin market for us. As discussed, we believe this is a temporary challenge in the U.S. market and are encouraged by the Q4 order performance in the U.S., which grew 9%, suggesting signs of gradual improvement.

Moving into FY '25, we will be monitoring the timing of order for revenue conversion as a leading performance indicator for recovery in the U.S. as this significantly contributed to slowing revenue in FY '24. Reflecting on our full year performance, I remain incredibly proud of what our team has accomplished and remain humbled by our mission, which is centered around advancing care and radiation therapy through innovation, expanding patient access to radiotherapy globally, delivering superior service and support to our customers.

We remain confident based on the positive secular trends in our industry as well as our ability to execute well and gain share in the markets we participate in. While global revenue was flat for the year, I am encouraged by the strong momentum in our international and emerging markets. Excluding the Americas region, international revenues grew 10% year-over-year for fiscal 2024. China revenue grew 27% year-over-year, whereas the rest of APAC grew 14% year-over-year.

Our IMEA region grew 8.5% year-over-year, driven in large part by higher growth subregion markets like India, Middle East, and CIS or the commonwealth of independent countries. Japan was down approximately 11% year-over-year, driven largely by the impact of FX. And as I mentioned before, the Americas region, most notably the U.S., continued to lag other regions declining 26% year-over-year.

Despite the near-term challenges in capital equipment budget cycles, we believe that the long-term potential of the U.S. market remains intact with the advanced age of the U.S. installed base of radiotherapy systems providing a catalyst for upgrade and replacement opportunities. We expect to see gradual improvement in the U.S. in the second half of FY '25 into FY '26 where we estimate more of a full recovery.

Moving on to service revenue for the full fiscal year. Overall revenue was down 1% year-over-year. However, recurring contract revenue grew 4.5% year-over-year. As we mentioned on prior calls, we believe that our service solutions business is a huge long-term opportunity for both revenue and margin growth. The expansion of recurring service contract revenue demonstrates underlying performance improvements from the early stages of our plan. These include [indiscernible] installed base, impact of pricing actions, investments that will improve system uptime and serviceability performance like our agreement with Airbus, which will leverage data and predictive analytics to help reduce customer downtime and reduce parts consumption. Finally, we introduced new service solution offerings like Cybercom for the CyberKnife System, physics solutions like our partnership with TrueNorth and advanced education offerings, which we will deliver in our global education centers like the newly opened innovation and partnership club, in Genolier in Switzerland. We expect these areas will drive top line and margin improvement while increasing overall customer operational improvements and satisfaction.

As we have articulated in the past, there are 4 major pillars of our strategic growth plan. Our first pillar is driving top line growth through innovation to advanced radiotherapy and solve our customers' biggest needs. During the year, we had several product introductions that strengthened our portfolio and further differentiated Accuray technology. Customer adoption of our new product innovation has been strong.

Notably, this included a 31% year-over-year growth in CyberKnife System orders. We believe the rapidly growing clinical trends towards shorter course of latest treatments in 1 to 5 sessions backed by clinical data over the long term for areas like prostate, lung and neuro treatments is driving the increase in CyberKnife System demand.

Additionally, many CyberKnife System customers report strong patient awareness for our CyberKnife System versus other treatment platforms with many specifically requesting to be treated on the CyberKnife System due to its strong branding and high precision capabilities. A key area of focus for R&D investment will be the expansion of next-generation capabilities for the CyberKnife System to further advance the use of stereotactic radiosurgery and SBRT and drive replacement of our installed base in the developed markets like the U.S., Europe and Japan.

Customer exception also continues to be strong at our Radixact platform, which represents approximately 70% of product orders in FY '24, driven by ClearRT CT Imaging, Synchrony and real-time motion management [indiscernible] which expands our breast treatment capabilities and CENOS online adaptive functionality that we introduced as the works in progress and are planning a full introduction at ESTRO '25. Beyond penetrating the China market, we also intend to serve other high-potential markets where patient access to radiotherapy is challenged, particularly India, where we introduced our new Accuray Helix product at the Indian Cancer Congress last fall.

Today, we are announcing that we have obtained CE Mark clearance for this product in the press release to follow and will ship our first unit to India in the coming months. Our next strategic pillar is expanding and growing our service business, we set out a multiyear plan to strengthen our service business, which represents a recurring revenue stream and margin expansion opportunity. Our service revenue has been essentially flat over the last decade and currently represents 48% of our global revenue for fiscal '24. Service contract revenue growth is largely gated by growth of our installed base.

In FY '24, we saw an expansion of our global installed base in 3 of our 4 regions, driven by meaningful growth in the APAC region and healthy growth in both EIMEA and Japan regions. We're taking a longer-term approach in the U.S. with focused commercial investment, expanding our commercial footprint with the goal of ensuring the highest level of service and customer satisfaction. So, we're best positioned in competitive replacement cycle as well as upgrading our own installed base. Expanding margins and profitability and improving our balance sheet with our third pillar.

In 2023, Ali and I laid out a multiyear multifaceted plan to drive margin expansion and cost efficiencies with the goal of leaving no stone unturned. While we have made good progress against our goals with actions that have helped us to navigate the impact of inflation, logistics costs and foreign exchange fluctuations, we are still in the early innings of improvement and believe that we have laid out a strong foundation to show material improvement to margins as macro factors improve and as we increase scale.

Finally, in FY '24, we strengthened our existing strategic partnerships with GE Healthcare and Research and also created new ones like our product development partnerships with C-RAD, Limbus AI, Radformation, and service partnerships with Airbus and TrueNorth. We believe these alliances help us bring best-in-class solutions to the market faster, improve our sales funnel and enhance our win rate.

I wanted to take a moment and highlight some of the key milestones in FY 2024 that have put us in a more favorable position going into FY 2025. We enter FY '25 with a strong backlog of orders, which at $487 million represents over 2 years of product revenue potential. From a demand perspective, we saw global orders grow by 10% year-over-year for the full year an annual book-to-bill ratio of 1.5, exceeding our goal of 1.2.

On the operational side, we completed the first full year on our new SAP ERP system without major negative disruption. I'm extremely proud of our team as this was a foundational milestone for the company. I expect continued productivity benefits and better data and analytics to help us make improved operational decisions to drive further efficiencies. As I've mentioned on past fall, working capital will be a key part of cash flow improvement, and we delivered a $21 million reduction in total net inventory from Q3 and $7 million reduction for the fiscal year. This remains a priority for us going into FY '25.

And finally, entering into the Type B market in China has been a long journey for us, and I am pleased with how we have worked at the cross-functional team to ramp up our joint venture manufacturing site in Tianjin, completing the first 10 system bills of Tomo C and executing our first customer shipment of Tomo C in June to Shandong Hospital. With these key milestones behind us, I believe we are well positioned to execute our strategic growth plan in FY 2025. The U.S. remains challenging, and we will continue to monitor key performance indicators.

Additionally, we will closely watch market China market conditions, including any remaining slowdown due to the anticorruption campaign in addition to the timing of the China stimulus program, which we believe can be a potential tailwind aimed at replacement opportunities. These factors could impact demand for installations in FY '25, but believe these are timing related and difficult to predict exact timing trajectory and therefore, remain included in our guidance that we wait to see stronger signals of U.S. market recovery.

And in summary, I'm proud of the foundation we except for future growth. We achieved strategic customer wins in the marketplace penetrated new markets and forged key partnerships that enhance our solutions and improve our competitiveness. While we are still early in our transformation, we end the year to drive top line growth, gaining share in the markets where we compete with strong growth in margin and profitability over the coming years.

I will now turn it over to Ali, who will cover our financials.

[Ali Pervaiz, executive]

Thank you, Suzanne, and good afternoon, everyone. I would like to begin by thanking our global cross-functional teams who banded together and executed with unwavering dedication to deliver the strongest revenue quarter in the company's history. As we have mentioned before, fiscal year 2024 was a very important year for our company. Not only did we enter the value market of radiation therapy equipment to essentially double our addressable market we also continue to add more operational efficiencies to our business model, which continues to move the needle on our margin expansion plan. Although we face macroeconomic headwinds, particularly in the U.S. as well as unfavorable foreign exchange and inflation, we believe we are in a good position for growth in most of our markets and are well positioned when the U.S. market recovers.

Now turning to the quarter. Net revenue for the fourth quarter was $134 million, which was up 14% versus prior year and the highest reported revenue quarter in the company's history, exceeding Q4 of last year by $16 million, existing strong demand for our innovations driven by a 28% increase in year-over-year product revenue.

Net revenue on a constant currency basis for the fourth quarter was approximately $137 million, which represents a 16% increase versus prior year. On a full year basis, total revenue was $447 million, which is roughly flat from the prior fiscal year. On a constant currency basis, total revenue for the fiscal year was $448 million and represents a slight increase versus the prior fiscal year despite the Americas region being down 26% versus prior year.

Revenue in the Rest of the World grew by 10% year-over-year and made up 80% of our global revenue in fiscal year '24, which is a powerful indication of our continued strength in those markets. Product revenue for the fourth quarter was $80 million and up 28% from prior year and up 29% on a constant currency basis. As Suzanne mentioned, product revenue included 36 systems shipments, which is a new record number of ship shipments in the company's history and a 24% unit growth versus prior year.

On a full year basis, product revenue was $234 million, roughly flat from the prior year. Full year product revenue adjusted for the impact of foreign exchange was $235 million, representing a slight increase versus the prior year. Service revenue for the quarter was $55 million, down 2% from the prior year and flat on a constant currency basis, primarily driven by $3 million of lower revenue related to training and lower spare parts volume.

Notably, the contract revenue portion of our service business was up 4% or $1.8 million versus the prior year, which showcases growth in the mostly annuity part of the service business as our installed base continues to expand globally. Full year service revenue was $212 million, down 1% versus prior year. Service contract revenue was also a highlight for full year service revenue, which grew at 4.5% and contributed $8.5 million in additional revenue versus last year. This is noteworthy since contract revenue represents greater than 90% of service growth.

Gross orders for the fourth quarter were approximately $95 million and represented a book-to-bill ratio of 1.2%. On a full year basis, gross orders were $342 million and represented a book-to-bill ratio of 1.5%. Moving to the backlog. We ended the fourth quarter with a backlog of approximately $487 million, which represents greater than 2 years of product revenue, and we feel confident about the ability of this backlog to convert to revenue within 30 months.

As part of our diligence in ensuring a high-quality backlog, we canceled 3 units representing approximately $6 million of orders due to evolving customer dynamics. Our overall gross margin for the quarter was 28.6% compared to 31.9% in the prior year with a year-over-year decline primarily due to 2.1 points of higher margin deferral from China shipments and 2.1 points from higher parts consumption. Excluding each of factors, our reported gross margin would have been higher by 4.2 points implying year-over-year margin accretion.

As discussed in previous quarters, the China margin deferral is a delay of margin recognition until the final product makes it to the end user, and we expect to recognize all of the deferred margin in Q2 FY '25 and beyond. Parts consumption was higher due to a supplier quality issue we faced in the quarter that resulted in higher-than-anticipated failure rate of a critical component utilized in our CyberKnife platform.

Our engineering teams have worked closely with the supplier to identify the root cause and put appropriate corrective actions in place. We continue to monitor the quality issue and expect it will be resolved in the first half of fiscal year '25. Excluding the China margin deferral and the higher parts consumption, our gross margins would have been higher than prior year, driven by lower COGS due to productivity actions the team has prioritized along with higher contract revenue and pricing in our service business as part of our margin expansion actions.

On a full year basis, our overall gross margin was 32% compared to 34.4% in the prior year with the decline mainly driven by 1 point of higher China margin deferral, which we expect to contribute to margin beginning in Q2 of fiscal year '25 and 2 points of higher net part consumption versus prior year, which was partially due to the supplier quality issue mentioned earlier.

But foreign exchange overall served as a 30 basis point headwind for us in fiscal year '24, the Japanese Yen alone contributed to a 1.1 point headwind, which was partly offset by other global currencies during the year. Had the Japanese Yen not deteriorated by approximately 12% through fiscal year '24, it would have contributed an additional $5 million for our bottom line.

Operating expenses in the fourth quarter were $31.6 million compared to $38.1 million in the fourth quarter of prior fiscal year. The 17% year-over-year reduction was driven by improved efficiencies across the organizations, benefits from the restructuring we announced earlier in the year and a lower company bonus payout.

Operating expenses for the full year were $142.4 million compared to $151.6 million in the prior year, representing a 6% reduction year-over-year, showcasing focused cost control and we continue to push our teams to prioritize return on investment as part of our margin expansion actions. Operating income for the quarter was $6.8 million compared to a loss of $0.5 million from the prior year.

Operating income for the full year was $0.5 million compared to $2.4 million in the prior fiscal year. Adjusted EBITDA for the quarter was $10.1 million compared to $5.2 million for the prior year period. For the full year, adjusted EBITDA was $19.7 million compared to $23.9 million for the prior period. From a year-over-year perspective, there were 2 main factors that negatively impacted our adjusted EBITDA.

Firstly, we defer $5 million of additional China margin versus last year, which we know is a timing-related issue that will result in a benefit starting in Q2 of fiscal year '25 and will be normalized going forward now that we have the NMPA approval for the Precision Treatment Planning System.

Secondly, we experienced $4 million of higher parts consumption on which $2.4 million was related to a particular supplier quality issue, which we anticipate resolving in the first half of fiscal year '25. Without these 2 issues, our adjusted EBITDA would have surpassed last year, which points to the strong underlying operating performance of the business. We described the reconciliation between GAAP net income and adjusted EBITDA in our earnings issued earlier today.

Turning to the balance sheet. Total cash, cash equivalents and short-term restricted cash amounted to $69 million compared to $61 million at the end of last quarter. Net account receivables were approximately $92 million, up $19 million from the last quarter, with a record number of system shipments. Our net inventory balance was $138 million, down $21 million from the prior quarter. I'm extremely proud of the way our teams executed to improve working capital performance with a substantial decline in inventory and an increase in cash, which resulted in a $9.4 million of free cash flow generation in Q4.

In summary, fiscal '24 was a challenging year for us to execute due from a macro standpoint. While we saw inflation ease slightly over last year and the foreign exchange volatility, especially with the Japanese Yen, served as a big headwind that hampered our results. Additionally, the both of the U.S. market drove a 26% year-over-year decline in revenue from that region, which also happens to be a higher-margin region in our portfolio.

Despite with headwinds, our global teams worked tirelessly and were able to grow total revenue by 10% year-over-year, excluding the Americas, which also represents 15% year-over-year growth in product revenue, which will serve as a catalyst to our service business in the coming quarters. Another positive indicator for our business, there was a strong growth in service contract revenue of 4.5% year-over-year, which represents greater than 90% of service revenue.

I'm extremely proud of the financial discipline and operating rigor we have put in place over the last 2 years across our entire organization. Our teams continue to execute from an operational perspective and are laser-focused on margin expansion through pricing actions, service growth, operational excellence and focused OpEx management. While we've had many headwinds in gross margins, the hard work being done in all these areas above is helping to offset macro factors, and we believe will meaningfully contribute to our P&L in the near term once those exogenous factors dissipate.

Additionally, we are well positioned to accelerate our growth in APAC and EIMEA while anticipating the recovery of the U.S. market. Looking forward to fiscal year '25, I firmly believe that the new product innovations and service offerings we introduced in fiscal year '24, along with expansion to the value segment will position us nicely to drive extended period of top line growth and profitability. Based on the above for fiscal year '25, we are guiding to a revenue range of $460 million to $470 million and an adjusted EBITDA range of $27.5 million to $29.5 million.

This guidance range assumes the following key factors. Firstly, the U.S. market will begin to recover in the second half of fiscal year '25 delaying system revenue and associated margins and adjusted EBITDA in the back half of the year. Secondly, China margin deferral due to delayed NFPA approval of the precision treatment planning system to begin releasing starting in Q2 of fiscal year '25 and then normalizing in the back half of the year. Those are our key financial highlights.

And with that, I'd like to hand the call back to Suzanne.

[Suzanne Winter, executive]

Thank you, Ali. In closing, I'm incredibly proud of our global employees and the progress they have made this year against each of our strategic growth objectives. While we did not grow the way we had planned, we end with very strong fourth quarter performance. We have major regulatory approvals in place, including full Tomo C approval in China and CE Mark for the Helix platform. We have a strong backlog of orders, commercial momentum in the majority of our markets and strong customer demand for our unique radiotherapy platforms. Additionally, we've navigated a number of macroeconomic factors over the last couple of years, including inflation and foreign exchange headwinds and remain cautiously optimistic that as these conditions improve could provide a tailwind to our performance. All of this sets us up nicely to deliver to our guidance of 3% to 5% top line growth and greater than 40% EBITDA for the year. And advance our strategic growth pillars into the next phase of execution as we drive to deliver compelling solutions to improve patient outcomes and quality of life for patients diagnosed with cancer or neurological disease.

I will now turn it back over to the operator for Q&A.

[Operator]

[Operator Instructions] Thank you. Our first question comes from Xuyang Li from Jefferies.

[Young Li, analyst]

Congrats on a strong finish to the year. I guess to start just on the guidance. I was curious if you can talk a little bit more about it, how much Tomo C is in the guidance. What are some of the potential upside and downside drivers that can get you to the top end or lower end? And I guess within China, what are the expectations for either anticorruption impacts or stimulus impact.

[Ali Pervaiz, executive]

Thanks so much for the question. I think in terms of overall guidance, maybe starting with the bottom end versus the top end, I think really, the 2 big factors are the recovery and the timing of the recovery of the U.S. market, which would really take us to the higher end versus the lower end that continues to be delayed. So that's a significant factor. And then obviously, there is certainly a lot of different macro tailwinds that we continue to track as well.

So, I think those are sort of the 2 main factors that really determine the range of our guidance between $460 million to $470 million, the important one really being the timing of the U.S. market recovery. I think overall, when you think about our guidance for next year, maybe I can just provide some more color. If you think about revenue. We really think it's going to be a similar first half, second half performance that we've had historically, which is 45% in the first half versus 55% in the second half, which really is related to the demand profile that we're seeing for our customers.

I think one thing that is noteworthy in the first half is that we do expect seasonality between Q1 and Q2. Historically speaking, Q1 has been our lowest revenue quarter. Q1 of '24 perhaps was a little bit of an anomaly to maybe Q1 of '22, is a better representation of how we expect revenue to unfold in the first half between those 2 quarters. And then also in the back half of the year, Q3 tends to be a little lower revenue quarter and then we obviously have accused ramp up in Q4, which we experienced in this particular year.

Okay, so I think that's certainly very important to take into consideration as we think about revenue profile for next year. When it comes to our EBITDA profile, I would say it's somewhat similar in nature to what we experienced in fiscal year '23. And the biggest factor taking consideration over there is really our service margin and our service parts consumption. So, our overall service margin for the year was roughly 32.9% for the total year. In Q1 of fiscal year '24, it was 43%.

So, it was 10 points higher than where we actually ended the year. And that was artificially higher because if you recall, we had an ERP implementation that was completed in Q1 of fiscal year '24. And so we actually had almost $5 million of lower parts consumption that then trickled into the remainder of the year. And so, it is going to be important to ensure that as we're thinking about Q1, that was a one-off, and that's certainly not going to repeat.

And so again, that's one fact to take into consideration that as I sort of shared within the script, we do expect the China margin deferral to start to release in Q2 of our fiscal year, and that's really related to the fact that it is the year-end for our JV partner, and they've started to bring a lot of customers online, and they expect the bolus of shipments to occur in Q2 and beyond. And that's when we actually thinking about the release activity just starting to pick up. So, I think those are really sort of the way to think about the guidance in terms of low end versus high end and then also kind of how we think about the year on board.

[Young Li, analyst]

Okay. Great. That's a very comprehensive, very helpful. I guess maybe just to follow up, I was wondering if you can talk a little bit more about the contributions from Tomo C in China and where you're hearing from the anticorruption campaign side? And anything on the stimulus side?

[Suzanne Winter, executive]

Yes. Absolutely, as you know the Tomo C we're all celebrating are a very long time waiting for the final approval to really do a formal introduction, Certainly, our JV partner is very excited. We did ship our first unit to our first customer at the very end of Q4 and now they are working very closely to drive the remainder of the installations based on customer timing in the first half and of course, into the back half of the year as well.

But really, we think there'll be a search in Q2 in terms of the overall installations. I think that the response is very strong. And again, China ended the year very strong in order, to which will translate into revenue over the coming years. So, we're very enthusiastic about the potential is now that we have this clearance behind us. Just in terms of the anticorruption campaign, I think there's just a lingering sort of processes that have slowed down this past year, the process.

But again, it certainly hasn't turned us from the results that we are seeing. But we do expect that something will be the new normal. So, I think our teams have sort of built that is in their overall forecast that some things are just going to take longer. In terms of the stimulus, that is starting to roll out. Again, it's an interest-free loan that the government is providing in not just the health care but many industries. But it's really directed at replacement of older systems.

And so again, our team in China is positioning new customers to be able to try and access those funds. They have not -- we haven't seen that actually initiated yet, but we do expect that probably in the back half of the year, we'll start to see some contribution to that, but we have not built that in to our numbers until we start to see greater signal.

[Operator]

Our next question comes from Marie Thibault from BTIG.

[Marie Thibault, analyst]

I wanted to follow up a little bit on Japan. I heard that after you exclude the Yen headwind, there's certainly some like strong demand. I think in the past, you've said that you expected to see a strong backlog come through in that country. I'm curious if some of that came through in this quarter? And how long we might expect some of that demand to last?

[Suzanne Winter, executive]

Thanks for the question, Marie. Yes, I think that Japan Q4, did come through with some strong revenue performance. It is a developed market, and we've talked about this in the past in developed markets. We do not have the same first growth rate in some of the emerging markets. But our Japan team is really going after competitive replacement. They have done just an outstanding job in terms of really going after aged installed base, not only ours but also our competition.

And again, we've talked a bit about gaining the #2 position, but we think they're on their way to being #1, just based on how they're trending at this point. So again, when you look at the Japan team and we think that they are based [indiscernible] the other regions, just in terms of really how to drive strong customer satisfaction. So, we do expect a continued important contribution from that region.

[Marie Thibault, analyst]

Okay. That's helpful. And then maybe talking about one of the more emerging regions that has a lot of opportunity. Congrats on the CE Mark for Helix. Can you tell us a little bit more about your plans there in India? Could we expect to see some orders get booked here in this fiscal year? And while we're talking about regulatory wins, have there been any updates from the FDA on CENOS since you submitted the 510(k) last year?

[Suzanne Winter, executive]

Yes. Let me talk about India first, we do have CE Mark, there's still a couple of more regulatory hurdles in India, but we do expect that to be in a shipping position by the end of our calendar year. But we are able to take orders now. So, the good news is we can start to build in funnel of orders within that region. And you're right, we see a lot of potential in India. And we believe that India has the potential over the coming years to be as big a market as China potentially.

Right now, we think it's about $100 million to $125 million market. We think that dealings will play very well there. But meanwhile, we are investing in our commercial footprint in India, as well as our back office and because we do believe the financial is very strong. And now with Helix [indiscernible] its market. Just in terms of the regulatory approval and CENOS, that is extended, I think, from what we had originally thought.

Again, we had gone back and we're having conversations with the FDA in terms of just making sure that we now have this cybersecurity requirements as well as some other requirements or nonhuman factors. So, at this point, we're planning for a full introduction at ASTRO, but we'll be in a shipping level probably by the end of the calendar year. So, we do think it will help us to win the new Radixact orders, but the revenues from CENOS will cost within [indiscernible] for the first half of FY '24.

[Marie Thibault, analyst]

Okay. Very helpful, Suzanne, just to clarify, more regulatory hurdles in India for Helix, is that things like treatment planning system or something else?

[Suzanne Winter, executive]

No, it's more of a [indiscernible] and it's more of a localization kind of hurdle what we need to do is make sure that we ship our first order, and then we have some alternative local body that does testing on it. And then we opened it up to greater shipments.

The next question comes from Brooks O'Neil from Lake Reach Capital Markets.

[Brooks O'Neil, analyst]

I'm just curious if you could give us a little more color on the U.S. market, in particular, maybe a little bit about the competitive environment. Do you feel like you're gaining share or losing share, gaining bunkers, losing bunkers? And what do you think the outlook is for fiscal 2025 in the U.S.?

[Suzanne Winter, executive]

Yes. Thanks for your question, Brooks. I mean I would say the U.S. market, when we talk about revenues, we're really talking about the delays that we see our customers counting from order to installation and getting the capital treatment priorities, we were able to install what we saw over FY '24 was a slowdown of lower priority for radiation therapy. But I think as we go into FY '25, what's playing out is what our customers have been telling us, which is they expected seasonal improvement in the back half of the. They have greater visibility. As a result, we have greater visibility. So, we think the back half of the year, we'll start to see it increase as more of a full recovery in FY '22. In terms of are we winning, our orders actually were good in the U.S. and overall, of the neighbors that grew in orders. So, we think that's very strong. We think it's faster than the overall market growth and that we are gaining share as a result of our strong customer reception to our new product innovation. So, what we're really looking at it, we take a look at the region for the year is what is the timing of new order to installation and can we help to accelerate that. And some of the things is better visibility. The other is making sure that we've got a very robust order to revenue process so that we work very closely with our customers and help them to get the priority.

[Brooks O'Neil, analyst]

Great. Let me ask one more. I appreciate the color. A year to go a lot of focus on margin improvement, service growth, would you say -- if I was listening correctly, maybe I wasn't, but it sounded like most of the service opportunity is perhaps more tied to due system shipments. And I guess the question really is, do you continue to see opportunity to drive growth in service and service margin?

[Suzanne Winter, executive]

Yes. Absolutely. I'll start and then I'll let Ali jump in here. Yes, I would say our service results for the year not tell the full story. I think that we did have some training and some installation revenue that's tied to the Americas installation that we've planned for events that affected our overall service revenue. But what's most important to us is growing that service contract revenue. That's the recurring part of the business. That is 90% of the revenue because these other things are more onetime factors.

And so, at 4.5% growth, we think that, that is a significant win, and we think there's still a lot more room for us to grow the service business not only from an increase in price of these new service solutions that we talked about like Cybercom, that we can now sell to our cyber line customers and a service contract. Greatly reduced their commissioning time as well as other value-added service solutions that we can bring to the table and also advance education. We've made a big investment in our global education centers including Genolier in Switzerland, innovation hub as well as one in China and one in Japan, and we have also invested to expand our training center in Madison. So, all of these things, we think we're in the early innings. We are certainly consciously optimistic at the 4.5% growth on the service rep contract revenue. And we think we've got more to go.

From a margin standpoint, I'll let Ali make comments.

[Ali Pervaiz, executive]

Yes. Suzanne, I totally agree with what you said. I mean, I think the important metric that we look at is how is contract revenue is growing, that is really representative of mostly the part of the service business. I mean, Suzanne mentioned that 4.5% year-over-year and just in dollar terms that added about $8.5 million of continued revenue into that particular line item. Okay? So, then you're asking why service revenue not growing at the same amount? Like I mentioned, that's being offset by some of the training, install revenue, mostly by lower activity in our less markets.

And then also spare parts revenue, okay? And spare parts we get impacted when we actually enter countries for the first time because our distributors are building up their spare parts and we actually had lower first in-country activity in this particular year. So, I would say that's all mostly timing driven, but it's not a good indication of the fundamental performance of our service business.

The contract revenue really is. So that grew 4.5%, which is both an indication of growing higher than our installed base and also the pricing activity that the team has been doing over the last 18 months. So, we feel good about that pricing activity is now starting to showcase into the P&L. Okay, I think the other element that's important to note is that we got hit with about $2.4 million of higher parts consumption related to a supplier quality issue. And so really had not been for that particular one-off. Our service margins would have been better by that amount.

I think we look at a lot of other operating metrics as well. I think the good news in terms of service parts consumption, which is probably the highest cost for service business payers is that overall, we volume parts consumed, we're seeing a lot of productivity. Where that being offset is by the impact of inflation, right? So last year, in fiscal year '23, we had almost about 3% inflation. And this year that grew by about 2.3%. And so again, a lot of that underlying activities the team is doing is being masked to buy a lot of these exogenous factors, and we do think that once you can guide these factors start to dissipate, not only by themselves, but also schools the work that our teams are doing with our suppliers, with our engineering teams, that will meaningfully start to showcase in our P&L.

So, I would say margin expansion is still very much front and center not only for our service business, but also in just overall COGS reduction activity. We did a lot of that in-house activity initially. But now we're actually actively engaging with our suppliers to really utilize our partners to understand how do we start to accelerate this activity going into fiscal year '25. As a matter of fact, we just had our first supplier summit earlier this month. And that's exactly the type of partnership we're looking for from our suppliers is how do we continue to reduce the cost of activity as we anticipate our volumes to pick up.

And our next question comes from Jason Wittes from ROTH Capital.

[Jason Wittes, analyst]

So, in terms of your service revenue and how you're growing it, is that largely pricing initiatives? Or are just higher take rates on service contracts, trying to understand the mechanics behind the optimism there?

[Suzanne Winter, executive]

Yes. Well, it's definitely the growth of our installed base. So, we have a strategy of going to emerging markets that were high growth, build installations then generate service contract revenue. So that's really the big driver. But we also have -- we are starting to see pricing actions come through the P&L. And so that's also been very encouraging. And then we believe that in the future, we'll start to see more contribution to the growth rate from really value-added sort of offerings that are new and could be a source of growth for higher value than our -- what we provide to our installed base.

[Jason Wittes, analyst]

Okay. And then if I think about your growth over the last several years, it's kind of mid- to high single digits is kind of in the range. Part of that's half of your revenue being service, the other obviously being capital equipment purchases. But with this new initiative to go after emerging markets and now that your kind of set up both in China and India, I assume that's all incremental. And is that potentially going to push you guys more towards double-digit type growth? Or how do we think about this opportunity sort of progressing over the next couple of years?

[Suzanne Winter, executive]

Yes. I mean, again, if you look at the year-ended up flat from a revenue perspective. But our international revenues grew by 10% and so just significant growth, it was really the U.S. that was down significantly that -- so what we believe is when the U.S. recovers because we do think of the temporary our international growth will be incremental growth in that can drive higher overall outlook from a revenue perspective. So that's why we're being prudent here in our revenue outlook for this next year as we watch to see the U.S. market recover.

And again, the U.S. market has tremendous potential because [indiscernible] across the market. There is an opportunity for replacement and upgrades. So that is going to be the catalyst for the U.S. market. And again, we think this past year was an anomaly of what is happening in the U.S., and we will continue to watch it to see when the timing of improvement.

[Jason Wittes, analyst]

Okay. And then also related to emerging markets. I guess it's my assumption, and you can correct me that those -- both the product sales and even the services are going to be at a lower margin than your current base, yet you guys are looking to continue to expand margins. So how does the math work with that? Am I wrong about my assumptions about the margins for the emerging markets being lower? Or is it just economies of scale working its way through the P&L?

[Ali Pervaiz, executive]

Let me take that one. So, I would say your comments are absolutely right that as we penetrate into the value segment in these emerging markets, we do expect our product markets to pressured. And as a result, our gross margins will likely stay consistent or would be pressured slightly. And the I think it is because we expect that pressure on product to be offset by the activity that we're doing on service. And so, at a gross margin level, it's likely going to be some pressure.

But really, I think we're going to get accretive on our overall EBITDA and EBITDA as a percentage of revenue, which is what we're looking to expand. And all of that's really driven by municipal phenomenon of volume leverage with the more volume that we have, we don't expect our costs to go up in the same way, and that should mainly contribute to margins and adjusted EBITDA level.

[Jason Wittes, analyst]

Okay. That's very helpful. And then maybe just a quick follow-up. I know you mentioned at the beginning that the guidance range is related to when the U.S. recovers. Just to clarify, at the bottom end of the range is assuming no U.S. recovery and the top end is assuming a second half recovery? how do we think about that?

[Ali Pervaiz, executive]

The midpoint is assuming U.S. recovery in the second half and then the bottom end could be impacted depending on the timing of that moving around and then same comments for the top end of that. So obviously, something that we are watching very, very closely, and we are really getting very intimate with our customers that we expect products in where the revenue is and then also obviously [indiscernible] service business over there. So, I think just by focus on overall U.S. business, but I think that's a right way to think about it.
