Thank you, Caroline. Good afternoon, everyone and thank you for joining our fourth quarter and full-year 2016 conference call. As you know, today is my last day as the CEO of Inogen and Scott Wilkinson will be taking over as President and CEO, effective tomorrow. I will continue to be involved with the Company on our Board of Directors and I have high confidence in Scott's ability to continue to drive profitable growth at Inogen. I would like to relay what a pleasure it has been to serve as the CEO of Inogen through these last nine years, growing from $10.7 million in revenues in 2009 to over $200 million in revenues in 2016. We have changed the lives of thousands of oxygen patients worldwide and I'm proud to have been the leader of this great organization. I also believe that this is only the beginning for Inogen, as we're still only at approximately 8% penetration in the Medicare markets in the U.S.. I would also like to express my thanks to the 600-plus Inogen employees, who have been so critical to our success in taking our vision and making it a reality. On our call today, Scott will start with the financial and Business highlights and cover our recent operational developments. And Ali will review the financials and provide updated 2017 guidance. At that point, we will open the call up for your questions. And with that, I would like to turn it over to Scott Wilkinson. Scott?

Thanks, Ray. On behalf of Inogen's Board of Directors, our employees, our investors and our business partners, I would like to thank you for your service at Inogen. Your leadership has been both beneficial to the Company and to me personally, as we have worked so closely together throughout your tenure here. I too am excited about Inogen's future and I look forward to leading this organization through its next growth phase. Looking at the fourth quarter of 2016, we continued to build on our success in prior quarters and we saw solid performance with revenues of $50.9 million. This represents 25.7% growth over the same period last year, reflecting great results in our business-to-business sales channels, both domestically and internationally and solid results in our direct-to-consumer sales channel. The expected decline in rental revenue was more than offset by the increases in revenue from our direct-to-consumer and business-to-business sales channels which continued to show strong growth. In the fourth quarter of 2016, we delivered net income of $5.3 million and adjusted EBITDA of $10.9 million, demonstrating that we can deliver solid bottom-line results, while scaling the sales of our new product, the Inogen one G4 and despite the expected rental reimbursement headwinds. For the full-year 2016, we delivered net income of $20.5 million, reflecting 77.1% growth year over year. And adjusted EBITDA of $43.4 million, reflecting 34.3% growth over 2015. Turning to revenue, the continued growth of sales revenue demonstrates the demand for our portfolio of innovative oxygen concentrators remains very strong across all of our sales channels. For the full-year 2016, total revenue was $202.8 million, up 27.6% compared to 2015. Domestic business-to-business sales were our strongest growth channel in the fourth quarter of 2016, increasing 69%, compared to the fourth quarter of 2015. Growth here was primarily…

Thanks, Scott and good afternoon, everyone. During my prepared remarks, I will review the details of our fourth quarter and full-year 2016 financial performance and then I will review our updated guidance for 2017. As Scott noted, total revenue for the fourth quarter of 2016 was $50.9 million, representing 25.7% growth over the fourth quarter of 2015. Total revenue for 2016 was $202.8 million, representing 27.6% growth over full-year 2015. Looking at each of our revenue streams and turning first to our sales revenue, total sales revenue was $42.6 million, representing 83.8% of total revenue in the fourth quarter of 2016 and reflected 47.2% growth over the same quarter of the prior year. Total units sold increased to 23,300 in Q4 2016, up 60.7% from 14,500 in Q4 2015. Total sales revenue for 2016 was $168.2 million, up 48% over 2015. Strong domestic business-to-business sales of $15 million in Q4 2016 reflected 69% growth over Q4 2015. And continued strong demand from our traditional HME providers and our private label partner. We also demonstrated strong international business-to-business sales of $12.1 million in Q4 2016, primarily driven by continued strong demand from our European partners. Sales in Europe represented the majority of international sales at 83.3% of international sales in the fourth quarter of 2016. With strong business-to-business sales again in the fourth quarter of 2016, average selling prices declined over the same period in the prior year, primarily due to the continued shift in sales towards traditional home medical equipment providers and private label sales and additional discounts associated with the increased sales volume worldwide. However, compared to the third quarter of 2016, average selling prices increased in the fourth quarter of 2016, associated with increased sales mix towards direct-to-consumer sales. Direct-to-consumer sales for the fourth quarter of 2016 were…

[Operator Instructions]. Our first question comes from the line of Margaret Kaczor with William Blair. Your line is open.

First off, Ray, congratulations, obviously, on the success you've headed at Inogen, it's been a great ride. Scott, congrats on the promotion, as well, obviously well deserved, hopefully you can add the same amount of success. The first question for me, you guys had some really great direct B2B sales and we're actually at the annual Medtrade meeting right now. The feedback here seems to be very positive, even more so than what we saw at the fall show. How would you guys describe the atmosphere of the traditional DME market today, relative to six months ago? And where can we get to six months from now and just because I like to do the math, what would it mean in terms of units and penetration of POCs if your sales to DMEs were to increase by 50% to 100%.

It's a good question. Margaret, it's one that in one form or another we've actually fielded throughout the last year or so, because we've continued to see growth in the B2B channel. As I've said in the past, this is a process, not an event, for the DME industry to change their business model and I think it will continue to be that way. There continues to be barriers that prohibit people from just turning their business over to a new model overnight. So, that is going to, I believe, prevent what a lot of folks would like to see in a hockey stick effect. This is going to be a transition that goes on for several years. We do seem to see momentum, we've seen it in our own business-to-business sales, a we hear the same buzz that you are hearing, so we're bullish on that, but we're also cautious that we don't get expectations ahead of what the market can actually bear. All of the traditional barriers for conversion are still there. The smaller DMEs tend to be undercapitalized, so they can turn their business overnight. The larger DMEs, while they tend have more access to capital, they've got a bigger restructure challenge, so it's just not that simple. We've talked in the past about people trialing the product and I've said at various conferences and I think on this quarterly call, that one man's trial can migrate into a slow conversion. We haven't seen anybody trialing product and backing off or anybody walking away and saying, well, I tried it and it was a failure and I'm going to go back to focusing on more efficient tank delivery. We've never seen that. We've just seen people continue, if they, say they're in a trial phase, they've continued to repeat their purchases. They may be expanding their trials, expanding into different regions. And again, I think that flurries into a market conversion, but that conversion is going to take several years. If you listen to Ali's comments on guidance, we tend to be a little more bullish in the area where we have more control which is direct-to-patient, that's also the core part of our strategy and some of direct-to-patient also drives B2B sales, just from a cultural effect. But we have been a little more bullish in our expectations for the 2017 plan with regard to B2b than we have in the past and I think that's a signal that we think the market is going to continue to build in that area, but I will continue to caution that it's not going to be a short term event, it is going to be a long term process.

I think the question really relates to when you guys talk about being 8% penetrated, we're not expecting the market to flip to 100%, but can you get that 8% to go to 15%, what would that mean for you guys, without requiring the market to flip?

Let's look at some of the growth rates that we have posted in the last year that have been pretty impressive. And tied to those growth rates are market penetrations of the one 1% to 1.5% annually. So, to go from a 8% to 15% and double is probably more than the market could swallow in a year. That would take quite an aggressive conversion and again, remember, you've got all of those other capital barriers. I would be surprised if it moved that fast. I wouldn't be surprised if we started seeing penetration change from 1% to 1.5% a year to maybe 2% to 2.5%, it might pick up a little bit, but it's not going to double the penetration in one year.

On the D2C side, [indiscernible] despite the fact that you slowed down hiring in D2C in Q4 and I think you even have sales reps down, so maybe talk to how efficient your sales staff was, why were they so efficient this quarter? Was it the G4, was it the CRM system? Why shouldn't we assume that same level of productivity over even increases from here as the G4 maybe fully rolls out. Thank you.

That's another good question. The one is really easy. There's nothing in our results in 2016 attributed to the new CRM system. While we started the project, a lot of the time and effort that's gone into it has been a planning phase. It will actually go live in the middle of this year. There's nothing from that, in fact, if anything, that just kind of curved our focus a little bit and it's one of the reasons that we did slow down in hiring, because you have the same people focused on planning for that system. You hit on the other one that's a success, is the G4. We spent a lot of time in the fourth quarter focusing on improving our scripting, honing that sales process. One of the successes that came out of that is we drove our mix from about a third to about 50% by the end of the year. We will continue that focus throughout this year. If you recall, we said we think our sea level point is at about 60%, 65% penetration, so, we're not there yet, that we made great progress in the fourth quarter. Why can't it continue in the future? Well, there's always puts and calls. We're going to continue to hire this year. In fact, you noted that we're going to -- we're running out of space in Texas, so we have got to open a facility. That's evidence of our commitment to continue to hire and grow our sales team and drive market penetration. I think we can continue to get some leverage out of the G4. Long term, we will get some leverage out of the new CRM system, but in the short term you'll actually take a step back. If anybody's been through a software conversion, they tend to be a headache. There's always some bugs that you have to work out and we expect that will happen. We've done software upgrades and changes in the past and you have to fight through some things. Like any year, there's going to be some puts and calls and that's all reflected in the guidance that Ali has noted.

Just to expand on that a bit, headcount on a year-over-year basis was up less than 10%, but revenue on the direct-to-consumer side was up 40%. We don't want to imply or have the takeaway be that the difference is productivity. There was incremental productivity improvements in the D2C team, both from the scripting side, as well as the launch of the G4 product, but that was more incremental in size of productivity increases and the rest was more around the timing of hires, when they happened, how many fully productive and seasoned reps we had out of the total pool, because that has a dramatic impact on the overall success of the direct-to-consumer organization. Versus the prior comparative period.

Our next question comes from the line of Robbie Marcus with JPMorgan. Your line is open.

I wanted to talk about the international market for a bit. You're going to have your first direct presence there. You had, I think it was off the radar for most of us, that South Korea came online. Maybe you could help quantify the contribution there and maybe talk about what markets you could potentially still enter that have reimbursement on your radar screen and how that could play out over the next 12 to 24 months.

Sure. Our focus, again, is primarily on direct-to-consumer. That's where we focus our resources, our growth. We've been very careful to not over-invest in B2B channels, whether it's domestic or international. On the South Korean opportunity, that was one that came our way, it took a little bit of investment in time and effort to work with the South Korean team to secure the proper registration and reimbursement for product. But you have to remember, while it's a nice upside for us in the fourth quarter, South Korea is still a relatively small market. It's not a market that we would have independently said, let's go after South Korea, that's a great opportunity. Again, when we're looking at what are we going to go after, set penetration in our own backyard, that's where our resources are. As these opportunities continue to come our way and they do, we will continue to assess them and look at what kind of resource do we have to invest to harvest that and we will take advantage of them, but I don't want to lead you to the idea that we've got a bulletin board here with a bunch of South Korean opportunities that we're going after, because that's not the case. It's about direct-to-consumer in the U.S.A.

To answer the question a little bit more directly, Robbie. It was less than 5% of our international revenues of fourth quarter that came from that South Korea customer. It still is a small portion of the $12.1 million international bucket in the quarter.

All right. Maybe to follow up on Margaret's question a bit and dive bit deeper. We've seen two quarters now of accelerated growth in U.S. B2B, a lot of that is or most of it is coming from the private label and the HME sales. So, maybe you could just give us a little more clarity about how you're thinking about 2017, D2C is expected to be your fastest growth channel, followed by the U.S., but may be peel back the onion a bit there and help explain what you're baking into those estimates, in terms of private label and HME sales.

As we said for guidance next year and kind of how we've always approached guidance, the closer we're to the end consumer, the more visibility we have on what we expect in revenue, in the areas that we're farther from the end consumer, we tend to be more cautious in our guidance. Inherent in our guidance range is that we expect direct-to-consumer to be our fastest-growing channel. We also expected that going into 2016, however, what ended up happening was both B2B domestically and internationally grew faster than our direct-to-consumer sales segment. So, that certainly is something that is just an approach in our guidance, because we're farther from the end consumer. On the domestic sales side, we do expect, when we say that we expect solid growth there, that that really is coming from the traditional HME side, either through our private label partner or through our own direct sales efforts. The reseller business, the Internet reseller business, has been growing much more modestly than the 69% we saw on the domestic side in the fourth quarter of 2016. So, that growth we expect will continue to be driven by traditional HME purchases, going into 2017 as well.

Okay. So, it's fair to say that there's a healthy dose of conservatism baked into your non-direct channel sales.

What I would say is, we're cautious about how quickly the HME community will adopt. We certainly see the large market opportunity that eventually POCs should be the standard of care, but how the HME community will get from where we're today to that point and the timing of that, we still are very cautious on that. While we've seen a great couple of years now of success of them really trialing POCs, we still feel like we're in the early stages the POC trials and as a result, we don't want to get out ahead of ourselves in terms of our guidance.

Our next question comes from the line of Danielle Antalffy with Leerink Partners. Your line is open.

I was just wondering if you could talk a little bit, maybe this is for Ali, about margins and how they differ between the business, because clearly, your B2B businesses are growing much faster, but I was under the impression from a margin perspective those are not the margins there are lower, so, I guess just a little bit of color on the split of the Business and how margins come into play here, because you're raising your net income guidance, so clearly, I'm wrong.

Overall, we see between business-to-business and direct-to-consumer relatively similar operating margins in those businesses. So, while the business-to-business side has a lower gross margin profile, it has lower operating expenses, as well. So, where that revenue comes from specifically on an operating margin basis, we're relatively neutral on that from a margin perspective. You will notice in the fourth quarter, we've continued to make nice progress on our gross profit or gross margin on the sales side of the business that came in at almost 50%, 49.9%. That's both an increase by increase and mix towards direct-to-consumer, but you also see that we're continuing to lower our cost to goods. On an average basis year over year, if you take our total sales cost to goods divided by our units sold, we're down about 15%. So, we have continued to take cost out where we can, based on higher volumes and design improvements that we've been able to implement that helps our overall margins and offset both the pressure we've seen on the average selling price side, as well as the reimbursement pressures that we've seen on the Medicare portion of the business.

And maybe just a high-level strategic question for you, Scott. You guys have quite a bit of cash on hand, note debt, can you talk about the Company's strategic priorities?

It's no surprise that we're going to continue to drive penetration of POCs in the market and that's what our core strategy is built to do, so we will continue to hire reps, we will continue to develop patient-preferred products. With a change in leadership, that's been our strategy for the last eight, nine years and that will continue to be our strategy going forward. Now, with the cash that we do have in the bank, I think we're in an outstanding position to take advantage of an opportunity if something comes our way from an acquisition or partnership standpoint, where some type of strategic partnership or investment made sense. So, we're in a great spot to have that at our disposal. But as far as what we're prospectively going after, it is executing the same strategy that we have over the last several years.

Our next question comes from the line of Mike Matson with Needham & Company. Your line is open.

You said that the G4 made up about half of the D2C sales business, but I was wondering if you could give us similar number for the domestic B2B business? What's the penetration of that adds the G4 into that mix?

It certainly is still pretty early in that launch. We really started ramping that up towards the end of the third quarter and then really into the fourth quarter, we didn't give a specific number there, but it is certainly well below 50%.

And then just within the web channel, I was a little surprised, you said the growth there was not really strong, but do you feel like the G4, from a competitive standpoint, I know a lot of those sites tend to sell a lot of the various products that are out there, if that positions you better so that you're able to pick up some share within that channel?

Within that channel, what's important to remember is that there are a certain number of resellers that sell our product and while they have seen improved productivity associated with the G4, just like we've seen on our internal side, they are also very much limited by the size of their sales force. So, their growth rate there follow much more closely to how they're growing their internal teams and they tend to not grow as quickly as we try and grow and the overall traditional HMEs are growing at this point. It's more having to do with their size of budgets of investments and headcount and media expense that drives their success on the direct-to-consumer internet cash buys, just like it does on our side.

Let me add to that for a second. We look at capacity in the market and obviously, we're expanding our capacity. What we don't want to do is flood the market with a bunch of resellers, so that there's more capacity than there is demand. So, we kind of watch that pretty carefully. If we get to a point where we think there's room to add another reseller, we will do that. It's got to be the right partner for us, too, not just anybody. But we're driving our capacity increase pretty hard, if you look at over the last five or six years at the expansion of our sales team, so we will keep an eye on that. But Ali is right, not all of the other resellers are looking to invest and grow their business at the same level as Inogen.

Okay. That's helpful in terms of explaining why the growth there is slower. But I guess what I was getting at is within those companies, they sell multiple products from different ESC companies, so even with the given number of sales people at their disposal, teams like with the G4 just being leaps and bounds beyond any competing products, you should be able to pick up more, a greater share of their business, if you will. Does that make sense? Have you seen any evidence of that?

It does make sense and we have seen, we have seen growth there. I think what happens is because the growth in that overall B2B bucket is being dominated by the home care providers, that it looks like their internet reseller growth is, it's much lower than their growth, but there is decent growth there. And G4 helped them just like it helped us.

Okay. And then finally, just with regards to the private insurers following Medicare's lead in terms of cuts, has that all run its course now or are you still seeing private insurers coming in and cutting more?

We're still seeing that, even into the first quarter of 2017.

Our next question comes from the line of Matt O'Brien with Piper Jaffray. Your line is open.

Thanks, guys, this is Matt, in for Matt today. My first question is actually on rental gross margins, so I know you guys are going to benefit from the Cures Act in the fourth quarter, but what would have been -- I'm sorry, you may have already answered this, but what would have been the margins for rental revenue there in the quarter?

In the quarter, excluding Cures, the gross margin would've been approximately 23%, excluding the $2 million benefit from Cures.

And into 2017, how do you expect that to trend? You've sequentially come down throughout 2016, so just sort of flatten out around that maybe 25%, 23% range or how should we think about that?

We haven't given specific guidance there, but the mass majority of the reimbursement cuts are now behind us. So, we don't expect to see large additional cuts to reimbursement rates, but you can tell they are already at pretty low rates from where they were a year ago. So, we do expect that from there we would continue to look for ways to improve our gross margin profile on the rental side of the business, through cost productivity on the rental states.

I'm showing no further questions at this time. Ladies and gentlemen, thank you for participating in today's conference. This does conclude the program and you may all disconnect. Everyone, have a wonderful day.
