Hello, welcome to the ResMed second quarter fiscal year 2023 earnings call. At this time, all participants will be in listen only mode. If anyone should require operator assistance, please press star zero on your telephone keypad. As a reminder, this conference is being recorded. It's now my pleasure to turn the call over to Amy Wakeham, Vice President, Investor Relations and Corporate Communications. Amy, please go ahead.
Great. Thank you, Kevin. Hi, everyone. Happy New Year, and welcome to ResMed's second quarter fiscal year 2023 earnings call. Thanks for joining us. This call is being webcast live, and the replay will be available on the Investor Relations section of our corporate website later today, along with a copy of the earnings press release and the presentation, both of which are available now. Joining me on the call today are Chief Executive Officer and Chairman, Mick Farrell, and Chief Financial Officer, Brett Sandercock. Mick will provide a brief high-level overview of our financial results, review our progress towards ResMed's 2025 strategic goals, and discuss our progress as we continue to navigate the ongoing macro, industry, and supply chain challenges. Brett will then review our financial results in more detail, and then move into the Q&A portion of our call.
During the Q&A session, Mick and Brett will be joined by Rob Douglas, President and Chief Operating Officer, and David Pendarvis, Chief Administrative Officer and Global General Counsel. During today's call, we will discuss several non-GAAP measures. For a reconciliation of the non-GAAP measures, please review the supporting schedules in today's earnings press release. As a reminder, our discussion today will include forward-looking statements, including, but not limited to, expectations about our future operating and financial performance. We do believe these statements are based on reasonable assumptions. However, our actual results may differ. Please review our SEC filings for a complete discussion of the risk factors that could affect our actual results to differ materially from any forward-looking statements made today. I'd like to now turn the call over to Mick.
Thanks, Amy and Kevin. Thank you to all of our stakeholders for joining us today as we review results for the December quarter, our second quarter of fiscal year 2023. Our financial results reflect solid performance across our entire business. Once again, driven by strong sales growth in the Americas region, as we were able to significantly increase both production and delivery of flow generator devices. We're seeing ongoing high demand for our sleep and respiratory care devices worldwide, and we're making steady progress working with our suppliers to continue to increase our production to ultimately meet the needs of all customers, and especially patients. Our mask sales growth was strong across the globe, reflecting a post-COVID pandemic awareness of the importance and need for respiratory hygiene and respiratory health.
ReSupply programs in the U.S. continued to drive solid, ongoing, sustained market mask growth, catalyzed somewhat by the end of calendar year deductible momentum in the U.S. geography. Mask sales across Europe, Asia, and the Rest of World also improved, driven by increased new patient setups as connected device supply increased. Our teams worked incredibly hard to achieve these extraordinary numbers in the face of an ongoing industry supply chain constraint market. We see the supply environment improving every week, every month, and every quarter, and our access to the specific electronic components we need has increased. We are confident in our ability to fulfill all customer demand before the end of calendar year 2023, and we expect to see steady, ongoing, incremental device revenue growth in the third and fourth quarters of our fiscal year 2023.
Customer acceptance of our reengineered AirSense 10 Card-to-Cloud device remained strong during the second quarter, particularly in the United States geography. As we increase the volume of fully connected AirSense 10 and fully connected AirSense 11 devices over the next few quarters, we will be able to phase out the AirSense 10 Card-to-Cloud device and refocus on our strategy, which is based around the growth of 100% cloud connectable devices across the globe. Outside the U.S., we have not seen the same adoption rates of that AirSense 10 Card-to-Cloud device. However, there have been pockets of success in some geographies, and we see a strong growth path going forward as we ramp up our fully connected AirSense 10 and our fully connected AirSense 11 products, and as we achieve regulatory clearance of the latter platform market by market.
To that point, we introduced our newest product, the AirSense 11 platform, into the Japanese market during December. We look forward to continuing to support doctors and patients in Japan with our world-leading 100% cloud connectable medical devices and our cloud-based software technology. Our number one priority across all of our markets will always be patients. Doing our best to help those who need treatment for sleep apnea, COPD, respiratory insufficiency due to neuromuscular disease, asthma, and all those who need access to out-of-hospital healthcare. Our goal is to ensure that patients get the care that they need, where they need it, and when they need it. Let's now briefly review our updates on ResMed's top three strategic priorities.
Number one, to grow and differentiate our core sleep apnea and respiratory care businesses. Number two, to design, develop, and deliver market-leading medical devices, as well as digital health solutions that can be scaled globally. Number three, to innovate and grow the world's best software solutions for care delivered outside the hospital, and especially in a patient's own home. The launch and acceptance of our AirSense 11 device platform continues to go very well. Patient feedback remains very positive, and we continue to see strong adoption of our myAir patient app. In fact, adoption rates are at more than double the adoption rate of myAir with the AirSense 10 platform at about 55% of all patients getting their data every day on their myAir app.
Increasing production and delivery of the AirSense 11 platform remains a top priority for our ResMedians around the globe. We will continue to achieve better results and stronger market penetration each quarter. Earlier this month, we were able to take our AirSense 11 fully connected device off allocation in the U.S. market. This is a very exciting development for our commercial team here in the Americas and for all of our customers. We look forward to continuing to expand the supply of fully connected AirSense 11 devices so that supply can become unconstrained in all countries. We will progress throughout fiscal 2023 on this endeavor.
An important aspect of our ResMed 2025 strategy is to reach hundreds of millions of patients with our respiratory care solutions, including non-invasive ventilation and life support ventilation, as well as newer therapeutic areas such as cloud-connected pharmaceutical delivery solutions and home-based high-flow therapy solutions. We are continuing to drive growth and adoption of our ventilator devices around the world, and we saw good uptake of both our life support and our non-life support ventilator platforms during the quarter. There is also ongoing adoption of Propeller's monitoring system. Its digital therapeutic platform is now integrated with the two leading U.S. electronic health record systems, Epic and Cerner. This digital health integration makes it easier for doctors and healthcare workers to onboard people to the Propeller platform. It's still early days for this technology.
Combined with our investments in home-based high-flow therapy for treatment of COPD in the home, we see this technology combination as an important clinical addition for treating lung disease and an integral part, an important part of our 2025 growth strategy. Turning to our Software as a Service offerings for outside hospital care, our SaaS business grew 18% year-over-year. This extraordinary growth includes sustained high single-digit organic growth of our U.S.-based SaaS business at around 7% and is accelerated by the addition of approximately 6 weeks of MEDIFOX DAN revenue. As we close that acquisition and welcome that German team into the ResMed family of SaaS solutions just over midway through the December quarter. We continue to grow with outside hospital care customers as they increase their utilization of our software and data solutions to improve and optimize business efficiencies and patient care.
As the post-COVID patient census continues to improve in our facilities verticals, we are seeing pent-up demand for technology investments that continue to come to the market. Our HME SaaS business under the Brightree brand continues to grow at a very rapid pace, and we welcome tech solutions for our HME customers across the U.S. market. As I just mentioned, during the quarter, we received final regulatory approval and closed our acquisition of MEDIFOX DAN, the leading provider of end-to-end software solutions for nursing homes and home health customers in Germany. We're now focused on integrating and growing this business as we accelerate SaaS innovation and SaaS growth in Germany and beyond.
I've met in person with many of the key leaders of the MEDIFOX DAN team, and I can tell you, I'm excited about the cultural fit, the technology focus, the sharing and learning opportunities that they bring and we bring to our global SaaS team. This is our first investment in an outside hospital software business beyond the U.S. market, but I can tell you the global SaaS team is very much in sync, and they have come out of the grade strongly, not just in the revenue growth I just talked about, but also in the soft side, team collaboration, transparency, and beyond. We look forward to updating you as we achieve key milestones in that business over the quarters and years ahead. Our team is ready to deliver.
Our SaaS business is an important part of ResMed's future growth and complements the incredibly strong software and device solutions that we have in our core sleep apnea and respiratory care businesses. One great example of the synergies between our SaaS business and our core business is the success of the Brightree ReSupply program. Brightree ReSupply automates the entire process from contacting the patient, interacting with the insurance company on coverage, and interacting directly with the patient on co-pays, as well as managing the logistics and distribution process. The ultimate goal is to keep a CPAP, APAP, or bilevel therapy user replenished with the supplies that they need to enable a better and longer-lasting therapy experience.
We have published clinical data that show that a patient on a ReSupply program has higher adherence to therapy. We also have peer-reviewed published data in CHEST showing, it's called the ALASKA study, that there is a 39% reduction in mortality for patients who are adherent to CPAP versus control. These are incredible data, they lead to these synergies not just being a good revenue opportunity, but being an incredible cost-saving opportunity for the healthcare system and life-saving opportunity for the patients involved. We will continue to identify and capitalize on synergy opportunities as we move forward. We are well-positioned as the leading global strategic provider of SaaS solutions for out-of-hospital care globally, we have created differentiated value for customers and long-term sustainable growth for our stakeholders. We are transforming out-of-hospital healthcare at scale, leading the market in digital health technology across our business.
We now have over 13.5 billion nights of medical data in the cloud and over 19 million 100% cloud connectable medical devices on bedside tables in 140 countries worldwide. We are liberating data to the cloud every day and unlocking value for patients, providers, physicians, payers, and entire healthcare systems and communities. We are leading the industry. I see this as just the start of the digital health marathon. I can tell you, we love the race. As the overlap between digital health and consumer tech industries continues, it is important to note that ResMed's Chief Medical Officer, Dr. Carlos Nunez, was recently named Chair of the Board of the Health Division of the Consumer Technology Association, or CTA. The Health Division is the fastest growing division within CTA.
The Health Division focuses on consumer-based technology-enabled health solutions to deliver better health outcomes for patients and reduce overall healthcare costs for the healthcare system. Their mission is fully aligned with our ResMed mission, and I'm delighted to see Carlos be recognized for his leadership. The sessions that he chaired at CES in Vegas a couple of weeks ago showed that ResMed's thought leadership and Carlos's thought leadership is helping to craft the future of digital health and bring it to consumers, as we have done over the past decade. We're excited about the ways Carlos and CTA's Health Division can help continue to shape our industry for the future, lowering costs and improving outcomes, and engaging consumers in their own healthcare. ResMed's mission and clear goal is to improve 250 million lives through better healthcare in 2025.
This patient-centric mission drives and motivates ResMedians every day. We made excellent progress towards that inspiring goal over the last period. During the last 12 months, we improved over 149 million lives with delivery of a device platform to a patient, a full mask system to a patient, or a digital health software solution. Helping people to sleep better, to breathe better, and to live higher quality lives with healthcare delivered right where they live, and mostly in their own home. Before I close, I want to once again express my sincere gratitude to more than 10,000 ResMedians now for their perseverance, hard work, and dedication, both today and every day. Thank you. With that, I'll hand the call over to Brett in Sydney, and then we will move and open up for Q&A from the group. Brett, over to you.
Great. Thanks, Mick. In my remarks today, I will provide an overview of our results for the 2nd quarter of fiscal year 2023. Unless noted, all comparisons are to the prior year quarter. We had strong financial performance in Q2. Group revenue was $1.03 billion, an increase of 16%. In constant currency terms, revenue increased by 20%. Revenue growth reflected increased demand for our sleep products across our portfolio and ongoing increased device demand generated by our competitor's product recall. Year-on-year movements in foreign currencies, in particular, the weaker euro, negatively impacted revenue by approximately $36 million this quarter. As mentioned, we closed the MEDIFOX DAN acquisition on November 21, 2022, accordingly, we've recognized MEDIFOX DAN revenue of $10.7 million in our Q2 FY 2023 result from this date.
While we continue to experience ongoing challenges in securing sufficient electronic components to meet market demand, we are now seeing a more predictable and improving supply chain environment. We expect to continue to deliver sequentially higher quarterly device revenue through the balance of fiscal year 2023. Looking at geographic revenue distribution and excluding revenue from our Software as a Service business, sales in U.S., Canada, and Latin America countries increased by 26%. Sales in Europe, Asia, and other markets increased by 8% in constant currency terms. By product segment globally, in constant currency terms, device sales increased by 25%, while masks and other sales increased by 13%.
Breaking it down by regional areas, device sales in the U.S., Canada, and Latin America increased by 41% as we benefited from incremental revenue derived from the introduction of the Card-to-Cloud device and improving availability of our connected devices. Masks and other sales increased by 11%, reflecting solid ReSupply revenue. In Europe, Asia, and other markets, device sales increased by 5% in constant currency terms, reflecting the ongoing supply constraints in those markets for our connected devices. Masks and other sales in Europe, Asia, and other markets increased by 14% in constant currency terms. Software as a Service revenue, including revenue from our MEDIFOX DAN acquisition, increased by 18% in the December quarter, driven by continued strong performance from our HME vertical. On an organic basis, SaaS revenue grew by 7% in the December quarter.
During the rest of my commentary today, I will be referring to non-GAAP numbers. We have provided a full reconciliation of the non-GAAP to GAAP numbers in our second quarter earnings press release. Gross margin declined by 80 basis points to 56.8% in the December quarter. The decrease is predominantly attributable to product mix shifts due to increased flow generator sales, as well as unfavorable foreign currency movements, partially offset by increases in average selling prices. Moving on to operating expenses. SG&A expenses for the second quarter increased by 14%, or in constant currency terms, increased by 20%. The increase was predominantly attributable to increases in employee related costs, additional expenses related to our acquisitions, and travel and entertainment expenses.
SG&A expense as a percentage of revenue was 20.5% compared to the 20.7% we recorded in the prior year period. Looking forward and subject to currency movements, we expect SG&A expense as a percentage of revenue to be in the range of 20%-22% for the balance of fiscal year 2023. R&D expenses for the quarter increased by 12% or in constant currency terms, increased by 15%. R&D expenses as a percentage of revenue was 6.8% compared to 7% in the prior year quarter. Looking forward and subject to currency movements, we expect R&D expenses as a percentage of revenue to be in the range of 7%-8% for the balance of fiscal year 2023.
Operating profit for the quarter increased by 14%, underpinned by strong revenue growth, partially offset by a lower gross margin. Our effective tax rate for the December quarter was 18.3% compared to the prior year quarter rate of 15.6%. Looking forward, we estimate our effective tax rate for fiscal year 2023 will be in the range of 19%-21%. Our net income for the December quarter increased by 13%, and non-GAAP diluted earnings per share also increased by 13%. Cash flow from operations for the quarter was $129 million, reflecting solid underlying earnings, partially offset by higher levels of working capital. Capital expenditure for the quarter was $27 million. Depreciation and amortization for the quarter totaled $38 million.
We recorded equity losses of $3.1 million in our income statement in the December quarter associated with the Primasun joint venture with Verily. We expect to record equity losses of approximately $3 million per quarter through the balance of FY 2023 associated with the joint venture operation. On November 21, 2022, we completed our acquisition of MEDIFOX DAN for consideration of $997 million. This was funded through a drawdown on our existing revolver credit facility. During the quarter, we recorded acquisition related expenses of $8.4 million associated with the MEDIFOX DAN acquisition. The acquisition was EPS neutral on a non-GAAP basis in Q2. We expect the acquisition to be mildly accretive to EPS on a non-GAAP basis in the second half of FY 2023.
We ended the second quarter with a cash balance of $253 million. At December 31, we had $1.8 billion in gross debt and $1.5 billion in net debt, reflecting the funding of our MEDIFOX DAN acquisition. At December 31, we had approximately $390 million available for drawdown under our revolver facility, we continue to maintain a solid liquidity position. Following the acquisition of MEDIFOX DAN, our net interest expense is expected to increase to approximately $15 million per quarter for the second half of fiscal year 2023, reflecting our increased debt position. Our Board of Directors today declared a quarterly dividend of $0.44 per share. Going forward, we plan to continue to reinvest in growth through R&D and also expect to continue to fund future tuck-in acquisitions. With that, I will hand the call back to Amy.
Great. Thanks, Brett, and thanks, Mick. Kevin, I'd like to now turn the call back over to you to provide the instructions and then run the Q&A portion of our call.
Certainly. We'll now be conducting a question and answer session. If you'd like to be placed in the question queue, please press star one at this time. A confirmation tone will indicate your line is in the question queue. You may press star two if you'd like to remove your question from the queue. One moment please while we pull for questions. Our first question is coming from Chris Cooper from Goldman Sachs. Your line is now live.
Thanks. Good morning. Good afternoon. Good to hear the fully connected AirSense 10 is now of allocation. Can I ask what happens with these CTCs, C2Cs that are effectively now are presumed surplus to requirements? Are there any sort of impacts on pricing or inventory valuation we need to think about in the second half?
Thanks for the question, Chris. It's a good one. Obviously, we're thrilled to have AirSense 10 fully connected now unconstrained in the U.S. geography. As you know, we operate in 140 countries worldwide. The AirSense 10 Card-to-Cloud inventory, we're working our way through that, and it actually is moving very quickly. I'd state it this way, that we've got the number one device in the market, which is the AirSense 11 fully connected, in terms of customer ratings. We also have the number two device in the market, which is the AirSense 10 fully connected. We have the number three device, the third best device in the market, which is the AirSense 10 Card-to-Cloud.
I believe that's better than the Tier 2, 3, 4 competitors that are in the market. We've got the number one, two, and three device there, and we're selling them. Different customers want different things. You know, certainly the AirSense 11 fully connected is at a price premium. But we'll start to see, I think us work through all of our inventory. The excess patient demand is still there globally, and I think we'll be there for a period of time, even after, you know, one of our competitors looks like they may come back into the market, you know, hopefully sometime this calendar year so that we can get our mask attachment rates onto them. Yes, Chris, we expect to work through all of that AirSense 10 Card-to-Cloud inventory. Good question.
Thank you. Our next question is coming from Suraj Kalia from Oppenheimer. Your line is now live.
Mick, can you hear me all right?
Got you loud and clear, Suraj.
Congrats on a great quarter. Hey, Mick, maybe I'm just trying to thread the needle here, but love to get some extra color. I heard you say by 2025, 250 million lives, that's the plan. If I use where you are currently, let's say 150 million, just rounding it off, that's a 70% almost jump in patient covered by CPAP. How should I think about the implied guide? Am I jumping the gun here? You know, are you sort of telegraphing you all should be in a position for the next three years, deliver about 17%, 18% CAGR? Thank you.
Suraj, it's a great question, and how we measure the lives changed is a pretty simple formula. Includes the CPAPs, APAPs, bilevel devices, but it also includes full mask systems, which, you know, the sort of linear growth, if you like, of the devices and some slight exponential growth of the mask systems because of replenishment rates and repeat customers coming back. But it also includes patients lives touched through digital health. So whether it's a Brightree patient who gets access to their device or other HME equipment, whether it's a patient in COPD medicines that gets an app that reminds them to take their medicine on a Propeller, or a patient that has a life support ventilator that gets a digital health reminder to get replenishment. You know, you are combining all those impacts on a life.
The way I look at it is, a life is changed as much by a brand-new device arriving in their house as it is by an app that helps them take a medicine that keeps them out of hospital. That's how we sort of look at lives changed. Yeah, $150 million calendar year 2023. You got it right. I mean, you got the math. The mathematics there is the CAGR is 17.5% volume growth of the lives that we touch over the next 3 calendar years through 2025. We're going to do that. We're going to get more and more patients on CPAPs, APAPs, bilevels, more and more on ReSupply and mask systems, and then more and more on our digital health platforms. We've got a...
It's a lofty goal, and it's a stretch goal, but we believe we can get there and change 250 million lives by 2025. Thanks, Suraj. Great question.
Thank you. Next question is coming from Matthew Mishan from KeyBanc Capital Markets. Your line is now live.
Hey, good afternoon, Mick. Just a quick question on the gross margins. Just how has the productivity of manufacturing and shipping improved over the last few months? Are you guys still working through, like, high-cost inventory? How much spot buying is there? Is sort of the decrease in gross margin or slight decrease in gross margin mainly on the mix of devices versus masks and accessories?
Matt, I'll start, and then I'll hand to Rob Douglas, our President and Chief Operating Officer, to cover in detail. Just at the start, there was a sequential decrease in gross margin. You know, one way, Matt, I could have avoided that is tell the team, "Don't sell all those CPAPs and APAPs that we've been able to create," right? Because it was great gross profit dollars to the business, and it was great to change a patient's life by a new device, but I could have kept my GM 70, 80 basis points up by saying, "Slow down those CPAP and APAP sales." Of course, we didn't do that.
The right thing is the humanitarian aspect to get those devices that we pivoted our supply chain, re-engineered and redesigned to get them to market, You saw extraordinary growth, 41% growth in our U.S.-based device market. Now, that's not our highest gross margin. It is dilutive to GM percentage, but it's contributory and positive to gross profit dollars. It's good for patients, and it's good for our stakeholders, so that's what we did. Rob, yeah, there's some really good first part of the question.
Yeah, Matt, there's. Thanks for the question. There's lots of factors in that gross margin, and you're asking specifically about productivity and productivity improvements. We've done a whole lot of work around volume improvements and really driving volume, and all of our discussions with suppliers have been increasing volume and reliability of delivery. Our normal settings in normal world is we have a long-term outlook volume commitments, and we're looking at optimization and pricing improvements and things like that. Those activities have pretty well been on hold while we've been doing these, you know, this sort of real scramble to drive volumes. Freight's a similar situation, although we are seeing, you know, freight's probably going to improve faster than some of these other costs that were in there.
Totally in terms of our supply chain culture, we absolutely will be aiming to go back to our continuous improvement situation, where we have, you know, a really strong volume leverage game. We continue to drive the volumes in a systematic way, and we use that to drive productivity and drive cost out of the system.
Thank you. Our next question is coming from Steve Wheen from Jarden. Your line is now live.
Thanks, Mick. I just wanted to follow up on that gross margin question. In the previous quarter, I think it was Brett was talking to the efficiencies that you're achieving through doing more volume and the margin benefit from that efficiency was sitting in your inventory balance. And that's obviously been building and built again this quarter. I'm interested, is that still the case that when that inventory comes off the balance sheet, we should automatically start to see the efficiency gains that you've been able to achieve to date?
Yeah. Brett, do you want to have a first go at that question?
Yeah. Yeah, Mick, thanks. Steve, yeah, I mean, that's. It. What we're doing, I mean, I think Rob articulated really at the moment we're optimizing for delivery rather than efficiency. We got things like we're running the three platforms at the moment, so I'm really focused on delivering, you know, devices to patients. That's having an impact.
The, the big one as we work through inventory or to wash through is the freight cost. We're seeing some reduction in freight costs, but that's not manifested in our P&L yet. That's more of a Q3, Q4. There will be some benefit that starts to wash through into Q3 and Q4 that we're not seeing yet that's currently still in inventory. On the efficiency side, we're really. We will get there, but we're optimizing on delivery for the moment. I think as we work through the fiscal, we'll be in a much better position to, to drive on efficiency measures.
You know, I'd just pile on there that you look at, you know, Brett's guidance, nice conservative guidance is that, you know, our gross margin will be sort of steady as we go forward. I look on this and say, I think there's some upside. You know, as we start to see mask rates start to improve, we saw 13% constant currency growth in masks during the quarter. I think, yeah, as Brett said, the freight costs will wash through the inventory. You know, we're getting great scale from the biggest respiratory medical manufacturing plant in the planet, there in Singapore. The efficiencies we've got are well above any competitor, and we're doing really well on that, and I think that'll come through.
In addition to that, you'll get some upside from MEDIFOX DAN, which is accretive to revenue, gross margin, and EPS, as Brett said, throughout fiscal and beyond. That'd be my guidance there as well, Steve. Thanks for the question.
Thank you. Next question is coming from David Bailey from Macquarie. Your line is now live.
Yeah, thanks very much. Morning, Mick and Brett. Just got a question on new patient growth. Just thinking about patients who've been prescribed a device and waiting, and then also those yet to be diagnosed. Just wondering if you could compare and contrast the U.S. and Rest of World, and then some comments on what you think it means for industry device growth for fiscal 2023 and 2024 relative to historical growth rates.
David, that's a great question. That's actually, the answer, we could take the whole rest of the Q&A session to go through it 'cause it's what we do, is trying to reach out to the 936 million people in our core market that suffocate every night with sleep apnea around the world, and we're laser-focused on it. As you saw, we delivered very strongly on those new patient setups. 41% growth of devices in U.S., Canada, Latin America. We turned it to positive there in Europe, Asia, and Other.
What I can tell you is we're really working through that excess patient demand, as, you know, those numbers will tell you, we're working faster through that excess demand in the U.S. and getting closer to a state where you get a prescription, and you'll get a device in days or weeks versus it got up to months there at the peak of the crisis. I think in, you know, you look across the other 140 countries we sell into, you know, every country is different. We've got to get the regulatory approvals for AirSense 11 there. We've got to work our way through, but we're going step-by-step on that journey.
So, you know, as I look at this excess patient demand, I made the comment there in my prep remarks, I think we will get to all of our customers' demand before the end of this calendar year. That tells you our confidence in increased supply and our ability to meet that need. We're laser-focused on that humanitarian emergency of patients waiting too long for therapy. We just don't want that. If you suffocate, this is a case of life and death. We've got the data to show that. We want your path to therapy to be expedited. In addition to that, the final thing I'll say is that we are looking at our patient demand generation activities that have been on halt these last 18 months.
I'm looking at our models in Australia, New Zealand, Korea, Japan, Singapore, U.K., and beyond, where we have these omni-channel markets availability to contact consumers or sleep-concerned consumers directly and get them into the funnel. Here in the U.S., we have direct models and also a joint venture there with Verily and Primasun that we've done some really good demand gen tests in a number of cities just waiting for me to fire the starting gun for that team. We're getting very close to firing that starting gun so we'll have a smooth flow from excess patient demand to now patient demand generation to continue our growth trajectory.
Thank you. Our next question is coming from Mike Matson from Needham & Company. Your line is now live.
Thanks for taking my questions. I guess, Mick, I think you mentioned high flow therapy in your prepared remarks. I just wanted to get an update on, you know, kind of where things stand with commercializing that and, you know, maybe talk about the just the market opportunity there. Thanks.
Look, it's a great question, Mike. You know, our long-term goal is there in 2025. You know, a number of those 250 million lives we're going to change in 2025 will be patients with neuromuscular disease or chronic obstructive pulmonary disease. Two of those great therapies, high flow therapy in the home, I want to be very specific. It's been used in the hospital during the pandemic. High flow therapy in the home, we see as a huge opportunity, probably 10x the size of our ventilation market in COPD is available for home HFT therapy. Propeller, yeah, early days, and the pilots are going well.
We're integrated to the payer-provider EHR systems, which gives us the credibility now to go from pilots to start to scale with some payer providers, particularly in the U.S. geography. Rob, any further details on our work on HFT and cloud-connected inhalers for Mike there?
Yeah, Mike. We're pretty excited about this. It's a long-term project though, but as Mick said, we view this as a very large potential market, very significantly larger than some of our other respiratory care markets. We believe that with running tests, we're really focusing on its complementariness with home oxygen therapy. That is, you'll get much better outcomes if you add this in. We're working hard on all of the market access and evidence generation programs to do that. Most of those programs are requiring either RCTs or real-world evidence trials. We're sort of in limited market release at the moment in specific markets where we're making these claims. As that evidence evolves and we generate it and take it to the payers and standard-setting organizations, we see this is going to be a very strong market for us, but it is a multi-year project.
Thank you. Next question is coming from Craig Wong-Pan from RBC. Your line is now live.
Thank you. Just a question on the SaaS business. The 7% organic growth that you mentioned, I was wondering if much of that was benefiting from price increases or if the price increases you started through the quarter have a bigger benefit to come through in future periods.
Yeah. Craig, thanks for the question. No, that doesn't include a whole lot of price increases. In fact, we put price increases on hold during the COVID pandemic in some of our SaaS businesses. We probably are changing to the area of price increases as we go forward. We've gone from pandemic to endemic. That will happen and then flow out over the coming 12, 24 months. I'm really excited. You know, we're looking at that domestic SaaS business in the worst of COVID getting down to low single digits. We moved to mid-single digits. Bobby, who's president of that division, and his team have really accelerated that organic growth to, you know, 8% last quarter, 7% this quarter, that high single digits organic growth.
Actually we see upside from that in the organic, if you think about it, Brightree, MatrixCare and CitusHealth path. We see opportunity to move that up. Then when you add on MEDIFOX DAN and its capabilities, I think the combined business, obviously the next four quarters will call out the inorganic part. It will be double-digits on the inorganic of course. But even going forward, as we look out towards 2025, we see opportunities for high single-digit and even low double-digit growth across that combined business as we lap the acquisition. Really good growth there. Price increases will be a part of that going forward, but they weren't historically, to answer your question directly.
Thank you. Next question is coming from Sean Laaman from Morgan Stanley. Your line is now live.
Good morning, Mick. Hope you're well. Mick, my question is, do you have enough visibility on the component pipeline to ascertain when you might be able to provide direct cloud connected devices in those markets that have an aversion to the Card-to-Cloud?
Yeah. Sean, I hope your Sydney morning is going well, day after Australia Day. Look, the way we're looking at this is we've got 140 countries. We've got a very complex supply logistics program to get the patients, you know, minimize the time from prescription to therapy across all those markets, but it's a complex equation. The good news is we are seeing supply of those rate limited semiconductors for communications. The 3G, 4G, 5G chips are starting to see supply come back. The microprocessors, the next rate limited step are starting to increase. So we're seeing, you know, we're seeing our path through this. You saw in the quarter, we were able to deliver incredibly strongly on that.
We're off allocation for the AirSense 10 100% connected. Look, I'd love to tell you we've got a very complex jigsaw puzzle here. I'd love to tell you we'll be off allocation on AirSense 11 in all of our markets. It's just not going to happen in the short term. As we go through this year, we'll update you as we go off allocation, and it'll happen market by market, geography by geography. Rob, did I miss anything there?
The only other comment, Sean, is some of this is driven by regulatory requirements around getting approvals and validations. Also, several of these markets have different components that they need, so there are different validation and engineering projects to do it, and we just have to sequence that through our prioritization process as well. That's actually true with all product launches.
The good news is it's not our first rodeo. We've done this, launch platforms in 140 countries many times before, and we're back to our, sort of, meat and potatoes here. This is what we do all day, every day. Going off supply chain constraints over the calendar year will be fantastic for us to be able to then just go back to what we do, which is helping people sleep better, breathe better, and live better lives outside hospital care. Thanks for the question, Sean.
Thank you. Next question is coming from Margaret Kaczor from William Blair. Your line is now live.
Hey, good afternoon, guys. Thanks for taking the questions. Good morning to Brett. I wanted to follow up on the growth drivers as we think about this and next year, 'cause, you know, I'm hearing there's patient backlog, obviously, there's core market demand generation that, you know, will start to pick up. Then, you know, from our perspective, we look at RePAPs as well. You know, how do you layer those together? Over what time period? You know, how much growth could you handle? Then maybe specific to RePAPs, since we haven't talked that much about them on this call, you know, where have they been in the last two years, you know, and when should they return to be a bigger piece of the mix itself? Thanks.
Yeah. Thanks, Margaret. It's a great question, and it's one we're thinking about a lot here, and we're thinking about all three prongs that you talked about. The first one, excess patient demand. How do we work through that? The U.S., we're getting close to really working through it. We've got 140 other countries, and as to Rob's point, it's a complex equation to get the supply chain and delivery at all 140, but we're working through that. Secondly, demand generation. Yeah, where we have omni-channel and have really established social media presences and abilities to drive demand gen, we'll be starting to turn those on country by country. Thirdly, RePAPs. To your point.
You know, the last 2.5-3 years of COVID crisis, pandemic crisis, competitor recall crisis, we have not turned the knob on RePAP. In fact, we know our customers have been holding back when they're supply chain constrained on contacting patients who reach that 3-year, 5-year post-warranty, you're ready for a new device on insurance and/or patient making the call. I think all three of those are going to be applied, you know, in all 50 states here in the U.S. and in all 140 countries worldwide. We do have scenarios and plans. I'm not going to detail them here on this call, but I can tell you that we expect to see steady growth throughout our market, and we're going to drive that, and we're going to make sure that patients' waiting lists are not long.
We're not going to turn the needles until we're ready to get there in supply. I'm just happy we're having this conversation this quarter, and it's so much better than the last eight quarters that we're talking about demand gen and driving RePAPs, because that's what we've done for 33.5 years in the business, and it's what we love doing, and we're going to do more of it.
Thank you. Next question today is coming from Matt Taylor from Jefferies. Your line is now live.
Great. Thank you for taking the question and good morning and good evening. I had a follow-up on that question. I guess I just wanted to understand, you know, what are your expectations, you know, if and when your competitor does come back? I mean, presumably there could be some, I guess, impact on flow gen, you know, that would create pressure, but maybe you get some pickup in the mask. Could you characterize, you know, how quickly you would expect things to change dynamically in both directions? Then how much juice can you actually get out of the demand creation and ReSupply to backfill or you kind of increase growth? You know, what are your pilot programs or places where you've done that telling you about how much of a quantitative pickup you could get?
Yeah. Thanks for the question, Matt. I'll start and hand to Rob for further detail 'cause it is a really important area for us. Look, if you think about, our competitor's been out of the market for 18 months, who knows, you know, we'll find out probably later this week, they've got an earnings call. Maybe they'll tell us what's happened with the consent decree and give us some timing. Frankly, give the market some timing, it'd be good. We've run scenarios that they come back Monday, you know, February 1, July 1. We've also run scenarios that it's January 1, 2024. Actually in all those scenarios, ResMed grows and ResMed does really well, and ResMed does a really good job of taking care of the unmet patient need.
If they come back early or come back Monday, we get a 60% plus or minus attach rate of our masks. We get good GM contribution, great patient care in terms of the best masks on the planet going to them and we're able to drive that. Now, they'll be starting from 0% new patient share. They're going to have to go and fight account by account. They won't be fighting against ResMed out the gate. They'll be fighting against the tier 2, 3, and 4 players who've come in to fill that part of the equation. They're doing an okay job. They have to fight against the okay players, and then they have to fight against us, the market leader.
I look forward to them coming back actually in terms of the mask side of business, it'll be really good. The scenario where it's further out, you know, it's later this calendar year or early next calendar year or beyond, we're okay with that too, because we're ramping up our supply, and we're going to get closer to meet all of customer demand in this. Frankly, it's not irrelevant, but it's not a big perturbation of our long-term strategy or our long-term business. We've got the scenarios and the little pivots that we need to have more masks or more demand gen in the different scenarios.
You know, I think investors are, and some analysts are thinking more about this, or worried, more worried about this than we are because we've thought so much about it and have the scenarios and the playbook ready for all three of those scenarios, and 2020 beyond. I look forward to this sort of people calling it a binary. I see it as a mild perturbation of a Monte Carlo sim that really doesn't change any long-term outcomes for ResMed and our patients, is not changed in any of those scenarios. Rob, any further detail for Matt here?
Yeah, Matt. The only other thing I'd add is we sort of think of sort of market growth rate in terms of the patient lifetime journey through this condition. Terrible condition, very serious. The biggest problem's awareness, you start off with how do you become aware of it? Does your primary care know to refer you to a sleep specialist? Can that specialist refer you to either home or lab testing? Do you get a referral to a provider who's got the capacity to look after you? Basically staff capacity is even a big issue for them. Will that provider look after you long term and keep the ReSupply programs?
Our solutions are across all of those, but there's bottlenecks in all of those parts of the patient lifetime, patient journey, if you like. As I say, we're providing solutions across that and incrementally driving improvements across all of those. That provides a really good long-term outlook for steady growth in the business, as Mick was saying.
Thank you. Next question is coming from Michael Polark from Wolfe Research. Your line is now live.
Hey, good afternoon. Two quick ones if I can sneak them in. Is there a vision or strategy to convert Card-to-Cloud products to connected solutions over time? Or is the base case to leave those units that have gone into the market over the last year or so as is? Then the second quick one is MEDIFOX DAN, the gross margin on that revenue ballpark, can you share what that is? Thank you so much.
Thanks, Mike, cheeky sneaking in two questions, but I'll answer both for sure. Card-to-Cloud, you know, as those devices, as those AirSense 10 Card-to-Cloud devices reach their either warranty period or payer allotted period at which a patient can get another device allocated to them, which is, you know, usually in that 3 years or 5 years normally time horizon, those patients will get the opportunity to upgrade their devices from an AirSense 10 Card-to-Cloud to presumably an AirSense 11 device. You know, look, first 26 years of ResMed's existence, we had firstly non-connected and then Card-to-Cloud, pager-type technology, sort of sneaker net. It works. It can get you there. It's not as optimal.
It doesn't get that sort of patient engagement on myAir and on all the abilities that we can get to that 87% adherence. It's darn good therapy. It's the smallest, quietest, and most comfortable therapy. With the Card-to-Cloud, our HME, mostly sold in the U.S., HME customers have done this for years. The data go to the cloud. The doctor doesn't see much difference 'cause the doctor's seeing all the data in AirView on Card-to-Cloud and directly connected. We're actually able to drive really good care with those patients. It'll be a bolus of patients over that sort of 12-month period. We've had, you know, I would say, some pretty good success in humanitarian aid, really, and showing that ResMed isn't just going to stick to a strategy.
It's going to say, "If we need to pivot tactically to take care of patients, we'll do it, and we'll take care of them long term." There will be a bolus of patients, I think, jumping at the front of RePAP in a couple years who want to get the latest and greatest technology, and some on consumer pay markets might go quicker. The second question around gross margin. Yeah, look, MEDIFOX DAN is accretive to our group gross margin. I'm not going to quantify it exactly, but that's why I said you're going to see, I think, some upside to our GM as we go through the fiscal year, including MEDIFOX DAN. It's accretive to revenue, gross margin percentage, but also NOP dollars and our EPS performance over the fiscal and beyond. Thanks for the questions, Mike.
Thank you. Next question is coming from Saul Hadassin from Barrenjoey Capital. Your line is now live.
Good afternoon, good morning. Thanks for taking my question. Mick, just a quick one. Just the U.S. flow generator growth rate of 41%, obviously very strong. Just wondering if you can give us any color as to within that, how much was volume versus price and also mix?
Yes. Look, it's a great question. You know, we don't split out our details on price. What I can give some sort of, you know, general color and maybe Rob, Brett, you know, maybe you want to add a little bit on for Saul to the color that we can provide. Competitive dynamics are very tight here. We were very open that we had a surcharge that we put the start of last year around the freight costs that were incredibly high, you know, $12 and EUR 12 across all devices and so on. We will, you know, start to actually take that away to get customer by customer and appropriately as we go through the year.
As we actually see, to Rob's point earlier, as we see those freight costs come through our inventory, they don't just come in a spot change. It takes time for the COGS reduction there to come through. In terms of that 41%, I can tell you it was materially improved by the AirSense 10 Card-to-Cloud, and was able to get those devices there. Our ability, I think also, you know, as we have at the start of this quarter to turn AirSense 10 fully connected off constraint, I think will continue to be a nice tailwind for our business there. Brett, I'll hand to you for any further color we can provide, to Saul to help on his modeling on this great U.S. flow generator growth.
Yeah. Thanks, Mick. I mean, the only thing I'd add, Saul, is that it was really the sleep devices or APAP devices was really strong. As we got device availability that went straight into the market. That was really kind of driving that, which is obviously, you know, higher volume devices than, say, bilevels, for example. That did definitely play a big part in that revenue growth.
Thank you. Next question is coming from David Low from JP Morgan. Your line is now live.
Thanks very much. Just a quick one. Mick, you talked about being unconstrained on supply by the end of the calendar year. I think it's to Sean's question, you talked about different markets and regulatory approval. The question I've got is, will the AirSense 11 be unconstrained more quickly in the U.S.? Can you give us any sort of sense as to when you expect that will be the case?
Thanks for the question, David. Clearly, AirSense 10 fully connected will be unconstrained first, just because that platform's been in the market for a long period of time. We've got all the inventory, all the capability to drive it, and it's regulatory approved in virtually every market, 140 around the world. It's just much easier to turn that off constraint and get it moving first. Yeah, to your point, you know, the, the smaller, the quieter, the more comfortable and the most connected and most clever device is the AirSense 11. As we get regulatory approvals, and we're going country by country on this, as we said, we just got Japan during the last quarter, and we're going to go country by country on this.
When we get regulatory approvals, as we get supply starting to improve on those components, we can really ramp that up with all its great technology and really good cost advantages and patient-friendly advantages. It's got coaching capabilities and interaction with the patient on the, on the screen that's interactive and can do some really good over-the-air upgrades, but also over-the-air interactions with physicians and its connectivity to myAir. 55%, I mean, almost, you know, vast majority of patients are being offered, and almost all of them are saying, "Yeah, I want to see my data every day and get a myAir score." It will go faster and less constrained in those markets where it has approval. I'm not going to predict the exact date that that will happen because we've got scenarios around that.
I think we will start to see that go off constraints before the end of the calendar year, because that's when we're going to be able to meet all the customer demand, which is our goal. We're on a fast track to do it this calendar year. Rob, what did I miss there on David's question?
Oh, the only other thing is, David, it's been really important for us to be able to supply those 2 platforms. It's been a great thing for us to have. Basically, we've got so much extra capability and capacity 'cause we've got 2 platform lines designed for the market.
Thank you. Next question is coming from Dan Hurren from MST Marquee. I'm sorry, Mark, your line is now live.
Hi, good morning, everyone. Thanks for taking the question. look, it's pretty clear that a lot of the growth is now coming from products that, you know, have been reengineered and didn't really even exist in their current form a little while ago. and we've seen the AirSense 10 connectors you're talking about, launched with parts from an alternate supplier and so forth. We've also seen some early regulatory approvals for an AirSense 11 with apparently different communication chips in. Just, is there any reason why that product couldn't launch within the next few months, as we've seen roughly the same timeline between approval and launch for something like the AirSense 10 connect?
Thanks, Dan. Clearly, you're very, very diligent looking at FDA and different regulatory approvals around the world. What I'll say to this is that the AirSense 10 Card-to-Cloud was a reengineered, repivoted device, absolutely. The AirSense 10 fully connected, we did rejig the comms chip to get one that was less supply chain constrained. Those two are reengineered and back in the line. We didn't reengineer the AirSense 11 that's selling right now. But of course, there will be variants. This is a long-term platform. This platform, the AirSense 11, is going to do CPAP, APAP, bilevel, all sorts of amazing therapy models.
You know, if you even look at the work that we're doing on the Lumis HFT device that we talked about earlier in the Q&A and during my prep remarks, that's on a platform of the AirSense 10. You know, obviously, AirSense 11 will become the platform of note for us over the coming years. We don't go into details of our future product pipeline. Thanks for the question. Look, I can tell you those three products in the market are number one, two, and three, and as you saw this quarter, they're selling well, and we expect them to continue to.
Thank you. Next question is from Lyanne Harrison from Bank of America. Your line is now live.
Good morning all. I might just come back to that full customer demand comment by the end of calendar 2023. Mick, is that in relation to just the new starts, or do you also expect that you'll meet the demand for the backlog of RePAPs as well that we've had over the last few years?
Yeah. Lyanne, you're getting to some of the complexities behind that. Look, our goal is to get off this supply constraint during this calendar year. We know we can get there. We won't get there if we turn on every single knob that we have for demand generation and RePAP generation around the world. We will be turning those dials, if you like, for demand generation and RePAP generation through our customers and directly as we get supply improving country by country. Yeah, I think we can get to all customer demand if we do no change faster. But our goal is to take care of not just the patients who are currently in the pipeline, but also the 80%, 90% in many countries who are undiagnosed and untreated.
Our mission is to do that, and it's aligned with altruism but also our profit motive. The overlap of those is a really powerful tool for us to have sustainable long-term growth as we have the last 33.5 years. Clearly, if we turned every dial to max, we wouldn't be able to get off, you know, a constraint this year. We won't turn all to max, but we will and we are starting to turn those dials and getting the programs up and running in different cities, different states, different geographies around the world as we start to get off constraints. I won't go into further detail than that to say that, Lyanne, yeah, you're digging in. It is more complex than just we get there.
We get there and then we start turning on the market growth rate as the market leader, which is our sort of our duty and our obligation, and we're going to do both. We're going to grow the market and grow our share and deliver for patients.
Thank you. Our final question today is coming from Steve Wheen. It's a follow-up from Jarden. Please go ahead.
Yeah, thanks for taking my question. This question's about the diagnosis rate in the U.S. in particular for OSA. There has been some frustration to the ability to diagnose patients. I just wonder what you're seeing from a during the quarter from improvement on that front with regards to diagnosis.
Yes, Steve. Thanks for coming for your second question at the end of the queue. It shows that the system works and you can get the second question in. It's a good one. Diagnostics rate in the U.S., obviously impacted at the start of COVID, with all the labs being shut down, and then we saw that big pivot and adoption of home sleep apnea testing and some great models from ResMed and many other players in the market to help physicians find ways to remotely screen, diagnose, treat, and manage sleep apnea patients.
You know, as we come out from pandemic to endemic in the U.S., we've definitely seen, you know, I'd say, you know, our data show that at least 50% of patients are going through home sleep apnea testing. Of the other 50%, some of them do a home sleep apnea test and then just a follow-up in a lab for titration and mask fit and so on. So really good adoption of home sleep apnea testing. Yeah, it's sort of related to our demand generation area. That demand generation isn't just, you know, going out there on social media and, advertising and finding that customer acquisition cost in an appropriate place well under lifetime value and getting them into the channel.
It's also working with the channel to understand where we have capacity, what cities, what geographies that we have. You know, as you know, Steve, following us closely, we purchased a company called Ectosense and their product called NightOwl, and I have one sitting on my desk right here. This thing is the size of my fingertip, and it has the ability to have highly sensitive and specific screening and diagnosis of sleep apnea and with reimbursement in a geography like the U.S. We're actually experimenting in Asia and Latin America and around the world on this. The technology is originally European, so hopefully it gets adopted there too. I love Ectosense, and I love home sleep apnea testing happening where it's small, it's quiet, it's convenient, and it's cloud connected, similar to our therapeutics.
I think you're going to see that diagnostics rate in the U.S. pick up post-pandemic 'cause people learn that telemedicine, digital health, remote screening, remote diagnostics work, and we can scale them. It won't just be here in the U.S. It might be pioneered and launched here and scaled here, but it's going to work in many other countries around the world. I can tell you we're really excited about partnerships with the physicians and the patients themselves to find their path to better sleep and better breathing. Thanks for the questions.
Thank you. We've reached the end of our question and answer session. I'd like to turn the floor back over to Mick for any further closing comments.
Thanks, Kevin. Thank you again to all of our shareholders and stakeholders for joining us on this call. I'd want to thank once again the opportunity for all 10,000 ResMedians, many of whom of you are also shareholders, so thank you for that. Thank you also for your dedication, hard work, helping people breathe, sleep, and live better lives in over 140 countries. You delivered these numbers. Thank you for all that you do. I'll hand back to you, Amy.
Great. Thank you, Mick. Thanks everyone for joining us. We appreciate your interest and your time. As always, if you have any additional questions or need a follow-up, please don't hesitate to reach out directly. This does conclude ResMed's second quarter 2023 conference call. Kevin, I'll turn it back to you to close things out.
Thank you. That does conclude today's teleconference webcast. You may disconnect your line at this time and have a wonderful day. We thank you for your participation.
