Greetings, and welcome to the Inogen 2023 Fourth Quarter Financial Results Conference Call. As a reminder, this conference is being recorded. It is now my pleasure to introduce Marissa Bych from Gilmartin Group. Thank you, Marissa. You may begin.

Great, thank you. And thank you all for joining today's call. Joining me are President and CEO, Kevin Smith; and Interim CFO, Mike Sergesketter. Earlier today, Inogen released financial results for the fourth quarter of 2023 and full year 2023. The earnings release is available on the Investor Relations section of the company's website, along with the 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, our 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 and 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 reports 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 presentations 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 noncash 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's President and CEO, Kevin Smith.

Good afternoon and thank you for joining our fourth quarter 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, 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 4th, strengthening our finance organization and stewarding our accounting, NFP, and ATMs. I am confident that both their additions are steps toward achieving Inogen's full potential. I would like to share insights into Inogen 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 introduction to the U.S. 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 fourth and full year 2023. We achieved $76 million in total fourth 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 in mobile patients using POCs with higher duration of autonomy at 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 in which we run our POCs via prescriber referrals. As part of the 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'll now turn the call over to Mike for a more detailed review of our financial results.

Thank you, Kevin, and good afternoon, everyone. Unless otherwise noted, all financial comparisons are to the prior year comparable period. Total revenue for the fourth quarter 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 fourth quarter, foreign exchange had a negative 50 basis point impact on total revenue and a negative 140 basis point impact on international revenue. Looking at fourth quarter revenue on a more detailed basis, direct-to-consumer sales decreased 21.6% to $19.8 million in the fourth quarter 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 percent to $18.1 million in the fourth quarter 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 fourth quarter 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 increasing cost of capital. General revenue increased 10.6% to $16.5 million in the fourth quarter of 2023 from $14.9 million in the prior period. Gross 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 fourth quarter, 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 first quarter of 2024 relative to the fourth quarter of 2023, driven by labor efficiency and lower impact from premium-priced components. Moving on to operating expense, in the fourth quarter 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 CEO transition and bad debt expense. In the fourth quarter 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 point impact on total revenue and a negative 40 basis point 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 an 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 the full year 2022. Adjusted EBITDA was a negative $37.8 million compared to a negative $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 first quarter. We expect first quarter 2024 revenue of $73 million to $74 million, reflecting growth of 1% to 3% compared to 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 into 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.

Thank you. Our first question comes from Robbie Marcus with J.P. Morgan. Please state your question.

Hi. This is Alan on for Robbie. Just my first question, I think when we look at your performance in the quarter, DTC stood out to us again, a 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?

Yes. 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. One is reducing the friction that's within the sales channels. We see opportunities there to continue to improve. The opportunities will 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 and 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 and started last month. We're working on it, but we want to ensure that we are maximizing the number of patients that we can reach each month. There are several aspects of the business where we're not prioritizing certain types of sales because of our incentive structure and we want to 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 kind of reining in costs is a key part of the strategy, but you ended the quarter with a little over $128 million. 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.

Yes, sure. So, 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 going to 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.

Our next question comes from Margaret Kaczor Andrew with William Blair.

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 the 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 I guess, I'm curious if you can also give us an estimate of what their market share was in the last year?

Thank you, Margaret. With the recent exits from the market regarding both the SOC and POC business, we are observing a shift in dynamics that we are closely monitoring. We believe there will be opportunities for us, and we are positioning ourselves to take advantage of them as they arise. However, this process will not happen overnight; it will take time. We are concentrating on these opportunities, which we anticipate will emerge across our various business channels, particularly in the B2B sector in the near term. The focus is less on average selling price and more on market availability and demand for POCs, where there may be a potential gap. I cannot provide specifics on the market share comparison, but we believe we hold a leading position which allows us to help fill that market void.

Okay. And 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 how big they might have been. And then I guess the real question is around first quarter sales guidance, maybe a little bit lower than we were expecting, and other than 2023, I'm not sure that I've ever seen it down sequential Q1 for Inogen 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.

Yes. So, with regards to the market share and the position, there have been certainly some shifts in that and I don't believe I'm in the right position to be able to comment on exactly who's number two in the market here right now. If we get more clarity down the road and I have more comfort in being able to address, yes, certainly will. And on the quarter-on-quarter, we see opportunities as I mentioned ahead of us. As we look at giving further guidance as we go out, I think we'll be able to give you some additional clarity, but 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 accelerate the growth as we go forward.

Okay. So I'm sorry, in the first quarter, you would just assume every business segment is down sequentially even with the way that you guys had presented the guidance on a total company basis. Is that correct?

So sequentially you said you mean Q4 versus Q1?

In Q4, we experienced growth in our international B2B market, while our domestic B2B was down. I believe these trends will continue in the near term.

Our next question comes from Mike Matson with Needham & Company.

So I guess, I know, Kevin, you've all been there for a few months, but the prior management team had kind of had the strategy where they were to some degree deemphasizing the DTC channel and focusing more on kind of the rental side of things and they weren't giving up on DTC, but they were scaling back the sales force somewhat and trying to just drive more productivity through the smaller number of reps. But so is that consistent with the way you're going to kind of run the business? And then there's kind of four channels here. They all have kind of different margin structures and different, I guess, call points. So maybe you could just tell us where you plan to focus investment between those four, if you know at this point?

Thank you for the question. When we analyze the various channels, we are identifying synergies within them. We have patients reaching out who want an Inogen POC, and we also receive referrals from prescribers where patients express the same desire. There is overlap among patients with insurance coverage who want a POC and those who may need a cash sale for various reasons. We are currently working on managing these distinct channels to reduce friction as we transition patients from one channel to another. Our goal is to optimize the number of patients using Inogen POC, irrespective of their preference or insurance status. For cash sales, we aim to facilitate the process with minimal steps, and similarly for those with insurance coverage, we strive for efficiency. While I may not have directly answered your question, we do see potential opportunities within both the rental space and DTC cash sales, despite the complexities in separating them into strict categories. This presents us with growth opportunities.

Okay. Yes, that's fair. And then just you commented on this partnership that you were going to, I guess, and I think you were referring to the prior management team had set up this physician prescriber sales force. I think it was around 60 reps, but I think maybe some of those reps were employed by a third party or something. I don't remember the name of that company off the top of my head. But is that what you were referring to? And I guess what happens to that sales force? Does it just transition over to Inogen and become Inogen employees or does that number 60, does that go up, does that go down?

Yes. So it's a fair question and a couple of answers to that is, yes, there was a third party within that prescriber channel that we went away from. We're bringing those sales reps in-house. We're restructuring how that looks a little bit for us to have more control, tactical control, and strategic control over that sales channel going forward. We are rightsizing that. I'm not going to comment right now on the numbers specifically in each of these sales channels, but it's important for us, one, to become profitable and to control those expenses. This was an opportunity for us also to control some OpEx, take some of that out by bringing that sales channel in-house. Again, it's important for us to have the right synergy within these channels going forward to operate as one Inogen. Bringing them in-house enables us to move forward with that plan as well.

Thank you. One last question about PhysioAssist. Can you clarify the timing and the regulatory pathway it needs to follow? Is it a 510K submission, and when do you expect to get it cleared and launched in the U.S.?

Yes. When we look at the Simeox and PhysioAssist coming in, what I will say is we're very happy with the progress that we've made. We've engaged with the FDA. We're working through that process. I'm not trying to avoid it, but I do want to 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. So at the appropriate time, I'll come back and I'll give you some more information on that.

Okay. Now that's fine. But I guess one follow-up on PhysioAssist. So you called that out 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 PhysioAssist or other new categories, I guess?

Simple answer, yes, we can. We can get POCs back to growth without relying on PhysioAssist. PhysioAssist wearing that into it, there are synergies within that device as well. There's overlay with the patients that will benefit from a PhysioAssist device, Simeox device as well as a POC that will help us deepen relationships, especially with commissions, as well as the B2B channel we see down the road. We do see a pathway for us to grow the POC business independent of Simeox.

Our next question comes from Mathew Blackman with Stifel.

Hi, this is Colin on for Matt. I had a quick one regarding U.S. B2B business, and how durable you expect the HME expense management to be from here? You talked about revenues being down in the fourth quarter and possibly expecting that to continue in the first quarter. 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.

And just one follow-up on the market exit from your competitor. Just wanted to confirm, is that in any way factored into the first quarter Q1 guidance?

No, it's not.

Thank you. And ladies and gentlemen, that's all the questions we have for today. And with that, we conclude today's conference.
