Greetings, and welcome to the Inogen 2023 Q4 financial results call. At this time, all participants are in a listen-only mode. A brief question and answer session will follow the formal presentation. If anyone should require operator assistance during the conference, please press star zero on your telephone keypad. As a reminder, this conference is being recorded. It is now my pleasure to introduce your host, Marissa Bych from Gilmartin Group. Thank you. You may begin. Great. Thank you all for participating in today's call. Joining me are President and CEO, Kevin Smith, and Interim CFO, Mike Sergesketter. Earlier today, Inogen released financial results for the Q4 of 2023 and full year 2023. This earnings release is available in the investor relations section of the company's website, along with a supplemental financial package. As a reminder, the information presented today will include forward-looking statements, including without limitation, statements about our growth prospects and strategy for 2024 and beyond, expectations related to our financial results for 2024, progress of our strategic initiatives, including innovation, our expectations regarding the market for our products, our business supply and demand for our products in both the short and long term. The forward-looking statements in this call are based on information currently available to us as of today's date, February 27, 2024. These forward-looking statements are only predictions and involve risks and uncertainties that are set forth in more detail in our most recent periodic report filed with the Securities and Exchange Commission. Actual results may vary, and we disclaim any obligation to update these forward-looking statements except as may be required by law. We have posted historical financial statements and our investor presentation in the investor relations section of the company's website. Please refer to these files for more detailed information. During the call, we will also present certain financial information on a non-GAAP basis. Management believes that non-GAAP financial measures, taken in conjunction with U.S. GAAP financial measures, provide useful information for both management and investors by excluding certain non-cash items and other expenses that are not indicative of Inogen's core operating results. Management uses non-GAAP measures internally to understand, manage, and evaluate our business and make operating decisions. Reconciliations between U.S. GAAP and non-GAAP results are presented in tables within our earnings release. With that, I will turn the call over to Inogen President and CEO, Kevin Smith. Good afternoon, and thank you for joining our Q4 2023 conference call. During today's call, I will provide insight into my experiences during my first months as CEO, outline our strategic priorities going forward, and share a few highlights from the recent quarter. I'm pleased to be leading my first earnings call here at Inogen. We have a great team and a great product portfolio. During my first months as CEO, I have observed and reflected on the strengths and challenges within our business, seeking substantial internal and external feedback regarding our portfolio, strategy, sales structure, field organization, and performance. I have spent much of my time visiting our global teams, investors, and management to understand the company from its roots. From my conversations with our leaders, I have immense confidence in the opportunity ahead of the company and our capability to make improvements across the business. As I strategize our path forward, I'm pleased to welcome two additional new leaders to our team. We are thrilled to have appointed Gregoire Ramade as Chief Commercial Officer in January. Greg's experience will help improve Inogen's products, commercial strategy, and customer experience. We also look forward to bringing on Michael Bourque as our new CFO, whose appointment we announced in late January. Michael will be joining the company effective next week, March fourth, strengthening our finance organization and stewarding our accounting and FP&A teams. I am confident that both of their additions are a step towards achieving Inogen's full potential. I would like to share insights into Inogen's strategic priorities going forward. Our top priority is positioning the business for revenue growth. An important piece of this process is the pursuit of regulatory clearance for PhysioAssist's introduction to the US market. PhysioAssist represents an exciting opportunity to expand our portfolio, increasing our ability to impact the lives of existing and new patients. We remain optimistic about our ability to achieve clearance, and we'll be providing updates as they're available. We will also be pursuing a return to sustainable profitability in the coming years. To this end, we are evaluating optimization of our production and cost structures with the intent to improve the cost of goods sold. Advancing our innovation pipeline with transformative technologies is also a key priority. We are advancing developments to make our products more accessible, mobile, and effective. This includes innovation within our digital health portfolio. Inogen devices are known for their superior patient compliance, monitoring, and diagnostic capabilities, and we know that continued investment in our platforms to improve their ease of use and cost-effectiveness can take us even further with our business-to-business partners, further establishing patient and provider preference and loyalty. In tandem with all of these efforts, Inogen will continue to bring best-in-class POCs to the market, evaluate our sales strategies, and strengthen our relationships with distributors and stakeholders in new and existing markets. We remain dedicated to delivering the highest quality, most dependable, and most advanced respiratory therapies to patients around the globe. Now I would like to highlight our accomplishments during the Q4 and full year 2023. We achieved $76 million in total Q4 revenue and $316 million in fiscal year 2023 revenue. Our recent sales were in part driven by the full launch of Rove 6 in Europe, which is progressing along well with our expectations. We have followed our 2023 achievements with several areas of progress in early 2024. For example, we saw a compelling conclusion supporting the adoption of POCs through a recently completed real-world evidence study. The study analyzed the effectiveness, burden, and cost of illness of over 380,000 long-term oxygen therapy patients. Baseline mobility was strongly correlated to lower risk of mortality over a 72-month period, and mobile patients using POCs with higher duration of autonomy had 9 months longer median overall survival, lower risks of hospitalizations and ER visits, and consequently, lower healthcare resource utilization costs than patients using POCs with shorter duration of autonomy. This further reinforces that patient mobility is key to their health and well-being, and using the devices that are compatible with it and do not restrict it have clear benefits. At Inogen, we take pride in the mobility our devices offer patients. We are always striving to find ways to improve mobility through battery life, device size, and weight to improve patient outcomes. In early February, we rolled out updates for our connected app and service portals to provide better patient monitoring and user experiences for our customers and business-to-business partners. Changes included the ability to connect to wearable diagnostic devices, ability to track patient breaths per minute, and error and maintenance notifications linked to specific devices. These changes are part of our broader effort to make sure Inogen devices are not only dependable but also practical for all users. In addition, we have initiated a shift within our rental channel through which we rent our POCs via prescriber referrals. As part of a continued effort to improve our rental process, expand the rental channel, and increase our forecasting and predictability, we are moving away from one of our external sales partnerships and bringing support for prescriber rentals in-house. I believe this is an important step, ensuring we are able to assist as many patients as possible. As always, we will continue to evaluate all of our business relationships and look for opportunities to streamline our cost structure. Before I turn the call over to Mike, I'd like to address the news of a recent competitor exiting the market. Due to this development, we are seeing some volatility in the domestic business-to-business channel, but we also see the potential opportunity to capitalize on our market leadership, differentiated product offering, and brand recognition. We expect that there may be a void in the market, and if so, we will be ready to step in and fill it. I now turn the call over to Mike for a more detailed review of our financial results. Mike? Thank you, Kevin, and good afternoon, everyone. Unless otherwise noted, all financial comparisons are to the prior year comparable period. Total revenue for the Q4 of 2023 was $75.9 million, a decrease of 13.8% versus the prior year period. The decline was primarily driven by a decrease in domestic business-to-business sales and direct-to-consumer sales, partially offset by higher rental revenue. For the Q4, foreign exchange had a negative fifty basis point impact on total revenue and a negative one hundred and forty basis point impact on international revenue. Looking at Q4 revenue on a more detailed basis, direct-to-consumer sales decreased to 21.6% to $19.8 million in the Q4 of 2023, from $25.3 million in the prior period, driven primarily by fewer representatives, partially offset by higher rep productivity. Domestic business-to-business revenue decreased 33.6% to $18.1 million in the Q4 of 2023, compared with $27.2 million in the comparable period, driven by competitive pricing pressure, increased cost of capital, and HME expense management. International business-to-business revenue increased 4% to $21.5 million in the Q4 of 2023, compared to $20.7 million in the prior period, primarily driven by the addition of PhysioAssist Simeox sales revenue, partially offset by competitive pricing pressure and an increase in cost of capital. General revenue increased 10.6% to $16.5 million in the Q4 of 2023 from $14.9 million in the prior period. Growth was driven primarily by an increase in the number of patients on service. Now, on to our gross margins. Total gross margin was 37.1% in the Q4, increasing 360 basis points from the prior period, primarily driven by lower premiums paid for components, warranty costs, and labor and overhead costs, partially offset by higher inventory-related losses. Sales revenue gross margin was 32.8%, an increase of 350 basis points, driven primarily by lower component and labor costs. Rental revenue gross margin was 52.7%, a decline of 120 basis points, primarily due to decreased reimbursement rates relating to insurance coverage mix, as well as higher servicing costs. We expect a modestly higher gross margin in the Q1 of 2024 relative to the Q4 of 2023, driven by labor efficiency and lower impact from premium price components. Moving on to operating expense. In the Q4, total operating expense decreased to $57.1 million, compared to $88 million in the prior period, representing a decrease of 35%. The decrease was primarily due to the loss on disposal of an intangible asset of $52.2 million in the prior year period, partially offset by the change in fair value of earn-out liabilities and certain one-time costs related to the CEO transition and bad debt expense. In the Q4 of 2023, we reported a GAAP net loss of $26.6 million and a loss per diluted share of $1.14. On an adjusted basis, we reported a net loss of $19.4 million and an adjusted loss per diluted share of $0.83. Adjusted EBITDA was a loss of $17.3 million. Moving on to our balance sheet. As of December 31, 2023, we had cash, cash equivalents, and marketable securities of $128.5 million, with no debt outstanding. Now to touch on full year performance. Total revenue for the full year of 2023 was $315.7 million, a decrease of 16.3% versus the prior year period. The decrease was driven by declines in direct-to-consumer sales, as well as domestic and international business-to-business sales, partially offset by higher rental revenue. For the full year, foreign exchange had a negative 10 basis points impact on total revenue and a negative 40 basis points impact on international revenue. Total operating expense was $236.1 million, compared to $238.8 million for the full year 2022, representing a decrease of 1.1%. Excluding the one-time non-cash impairment charge of $32.9 million in 2023 and the loss on disposal of intangible asset of $52.2 million in 2022, operating expense increased 8.9%, primarily driven by the change in the fair value of the earn-out liabilities. GAAP net loss was $102.4 million, compared to a GAAP net loss of $83.8 million for the full year 2022. Adjusted net loss was $48.3 million, compared to adjusted net loss of $26.2 million for full year 2022. Adjusted EBITDA was -$37.8 million, compared to -$13.5 million for the full year 2022. Before I turn the line back to Kevin, I would like to share our revenue expectations for the Q1. We expect Q1 2024 revenue of $73 million-$74 million, reflecting growth of 1%-3% compared to the Q1 of 2023. With that, I will pass the call back to Kevin for closing remarks. The start of 2024 opens a new chapter for Inogen. I remain optimistic for the future, and I'm excited to welcome the new additions to our management team. Our products are trusted and reliable, our innovation pipeline is robust, and we have a particularly exciting opportunity to increase our ability to impact patients' lives with the recent addition of PhysioAssist to our portfolio. While there's much work to be done, our team is equipped to handle the challenges ahead. Before turning it over for questions, I would like to take a moment and thank Mike for stepping in the interim CFO role for the past six months. His presence has been an immense benefit to myself and the company during this time. With that, I will open it up for questions. Operator? Thank you. Ladies and gentlemen, at this time, we'll conduct our question-and-answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate that your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment please, while we pull for questions. Our first question comes from Robbie Marcus with J.P. Morgan. Please state your question. Hi, this is Allen, onto Robbie. Just, you know, my first question: I think when we look at your performance in the quarter, DTC, you know, kind of stood out to us again, you know, pretty significant sequential step down. And then when we think about the guidance, it seems as though you're expecting that to stay relatively weak. So what are your plans for really stabilizing the business, and what gives you confidence that you can execute on that over the coming quarters? Yeah, sure. This is Kevin. So when we look at our opportunities here over the coming quarters to stabilize and grow the business, we look at three areas we're really focused on. It's, you know, one is reducing the friction. ... that's within the sales channels. We see opportunities there to continue to improve, the opportunities that allow us to grow the business. We also see some near-term opportunities within our B2B channel. Reducing COGS and controlling spend is another key focus for us going forward to improve our pathway to profitability. Also approval of the PhysioAssist and expansion of our digital health portfolio. But I've seen more positives than negatives. We have a good team in place, an existing product that is top-of-the-line, but we do see a lot of room for improvement within our sales strategy. We have a new Chief Commercial Officer, who we just appointed, started last month. We're working on it, but we wanna ensure that we're maximizing the number of patients that we can reach on each month. There's a number of aspects to the business, excuse me, where we're not prioritizing certain types of sales because of our incentive structure, and we wanna fix that. That incorporates both the DTC business, it looks at the rental business as a whole, as well as our cash sales. Got it. And then just thinking about your capital position, you just mentioned how, you know, kind of reining in cost is a key part of the strategy, but you ended the quarter with a little over $28 million. You know, how should we think about cash burn, whether or not you're confident that you can kind of steady the ship before you might need to raise more capital? Thank you. Yeah, sure. So, you know, at the end of the year, we had over $125 million in cash and equivalents, with no debt outstanding. We focused our investments on innovation within our pipeline, sales organization, and manufacturing capabilities. We're gonna continue to monitor and manage our expense and our cash burn. But we do believe that we have a strong balance sheet and capital position to fund our upcoming initiatives, and we don't anticipate going out for a raise. Anything to add there, Mike, that I missed? No, I think you covered it well. Thank you. Our next question comes from Margaret Andrew with William Blair. Please state your question. Hey, good afternoon, guys. Thanks for taking the question. I maybe wanted to go back to your commentary on some recent volatility in the market associated with a competitor leaving. I guess, what does that mean? Is that related to pricing? Is that related to demand? Were there things kind of intra-quarter? And, you know, I guess I'm curious if you can also give us an estimate of what their market share was in the last year. Yeah. So, yeah, thank you, Margaret, and, you know, with the, with the exits from, from the, the market, both on the SOC and the POC business, as I mentioned, we do see that there's a shift in, in dynamics there. We, we are closely monitoring that. We believe that there's gonna be opportunities for us, and we're putting ourselves in positions to be able to, to take advantage as they present themselves. But it's not a, it's not a light switch. This isn't a, this isn't a windfall. This is something that is going to present itself over time. We're focused on those opportunities. We see them coming... Really opportunities within our various business channels there, but we would anticipate more near-term opportunities within the, the B2B channel. But it's less on a, on an ASP aspect as well as, you know, market availability, demand for POCs, where there's a, where there may be a potential void. But that is, I can't really comment on, on their market share versus our market share. We believe that we have a leadership position in the market, and, and that is also giving us an advantage to be able to step in and help, and help fill that void, Margaret. Okay. I'll maybe tie these two questions together, but Can you at least say if they were maybe the number two player in the marketplace? I'm just trying to get a sense of, you know, just roughly, how big they might have been. And then, you know, I guess the real question is around first-quarter sales guidance. You know, maybe a little bit lower than we were expecting, and other than 2023, I'm not sure that I've ever seen a down sequential Q1 for Inogen, you know, in the- in my time covering the company. So is that related to a certain business segment, or can you give us a better breakdown by business segment? Thanks. Yeah. So, you know, in regards to the, to the market share and the position, it's... you know, there's been certainly some shifts in that, and, and I don't believe it's, I'm in the right position to be able to, to comment on, exactly who's number two in the, in the market here right now. If we get more clarity down the road, and I have more comfort being able to address, yeah, certainly, I, certainly I will. And, and on the, the quarter on quarter, we see opportunities, as I, as I mentioned, there ahead of us. And as we look at giving further guidance as we go out, I think we'll be able to give you some, some additional clarity. It's not necessarily tied to any one of the segments. We do also see upside within this, that we're working to position ourselves to be able to play. We're working through that process. I'm not trying to avoid it, but I do wanna be careful on giving any expectations about the regulatory approval until we have that firmly underway. We know we have clarity as to when that's going to happen. At the appropriate time, I'll come back, and I'll give you some more information on that, Mike. Okay. No, that's fine, but I guess one follow-up on PhysioAssist. So you called that out, you know, in the early part of your prepared remarks about kind of needing that to or relying on that to drive growth. So, maybe I'm misinterpreting what you said there, but, ... What does that imply for the POC part of the business? I mean, do you think you can get POCs back to growth without relying on, you know, PhysioAssist or other, you know, new categories, I guess? Simple answer, yes. Yeah, we can. We can get POCs back to growth without relying on PhysioAssist. PhysioAssist, layering that into it, there's synergies within that with that device as well. There's overlay with the patients that will benefit from a PhysioAssist device, a Simeox device, as well as a POC. That will help us develop even deeper relationships, especially with clinicians, as well as the B2B channel that we see down the road. But we do see a pathway for us to grow the POC business independent of Simeox. Okay, great. Thank you. Thank you. Our next question comes from Mathew Blackman with Stifel. Please state your question. Hi, this is Colin, on for Matt. I had a quick one regarding US B2B business, and how durable you expect the HME expense management to be from here. You talked about revenues being down in the Q4 and possibly expecting that to continue in the Q1. How durable should we expect this environment to be? We see good upside within the B2B channel. We've been working on relationships there, building synergies with the B2B, having direct conversations across the globe with our top B2B partners, to find out what are the best ways for us to work together to be partners and also reduce the friction between the channels, or direct channels as well as the B2B. So we see opportunities there for us to continue to build and grow that business. Just one follow-up on the market exit from your competitor. Just wanted to confirm, is that in any way factored into the Q1 guidance? No, it's not. Okay, great. Thank you. Thank you. Ladies and gentlemen, that's all the questions we have for today. With that, we conclude today's conference. All parties may now disconnect. Have a great evening.
