Thank you, Lynn. Good afternoon and thanks for joining us. Third quarter results continue to demonstrate strong execution and increased market penetration. We achieved third quarter year-over-year revenue growth of 47%, reaching $56 million, where our third quarter gross margins increasing by 1.5 points to 75.4%. Our initial guidance range of 37% to 40% growth has been increased throughout the year, driven by the increased confidence in our business outlook. Going into the last quarter of the year, we are raising our revenue guidance again. Now, we now expect full year revenues to be in the range of $215 million to $217 million, up from $212 million to $216 million which corresponds to 46% to 47% year-over-year growth. Our business continues to strengthen on many fronts, driven by the proven superiority and completeness of our Zio platform, comparative customer data confirms that adoption of our highly differentiated Zio platform enables customers to measurably diagnose more patients in less time with fewer unnecessary repeat tests and at lower costs. Zio platform also requires significantly reduced resources compared to other approaches. Our proven and complete platform consists of a technology stack with four layers that works seamlessly with one and other to create a source of competitive differentiation. So four technologies layers include a proprietary Zio data repository layer, that contains more than 600 million hours of annotated ECG based heart rate, heart rhythm and patient level information. In a data curation layer, that deploys proprietary artificial intelligence algorithms to reliably reproducibly and accurately share a massive amounts of collected heart rate, heart rhythm and activity information into actionable reports for medical management by prescribing physicians. And the information system layer that streamlines workflow processes by order entry, results reporting, capture, all relevant patient demographic and health plan information, physician notes and…

Thanks Kevin. Despite the challenges in our business that come in summer, the company continued to perform well as we head into the fall. Highlights for the third quarter 2019 were, revenue growth of $56 million or growth of 47% year-over-year and 5% sequentially. Gross margins of 75.4%, an increase of 1.5% year-over-year. Continued success moving away from non-contracted claims and improved claims adjudication efforts. Further reducing reserve requirements while improving overall ASPs. And finally a number of onboarding Zio XT account successes, which in turn accelerates adoption of Zio XT in those counts where we've launched AT. Demonstrating our capability of being the full service solution offering. Taking a more detailed look at the third quarter results. Revenue for the three months ended September 30th, 2019 was $56 million, an increase of 47% year-over-year and 5% sequentially. We were pleased with this outcome, given the headwinds associated with summer seasonality trends and lumpiness of launching large integrated systems during this period. We continue to view the pipeline is very robust, which is now enhanced with the full launch of our AT service offering here in October. Some of the trends we continue to monitor and communicate to investors include same store/new store revenue growth as expected rose during the quarter to just under 70% to 30%, given the challenges of launching new accounts during the summer months. We do anticipate a return to the more recent trend of 60% to 40% split as we move into Q4 and on into 2020. As a related item and a sign of continued strengthen existing accounts, our top 25 and top 100 accounts grew in excess of 40% year-over-year. A new trend we are communicating this quarter relates to our success with EHR implementations. In 2019, accounts that have implemented our service…

[Operator Instructions] Your first question is from Robbie Marcus from JPMorgan. Your nine is now open.

Hey guys, this is actually Allen on for Robbie, congratulations on the good quarter. I just had one question on the RUC process and then a follow-up. I guess my first one is, we know that you're moving from four, I believe to eight codes, but this was I think the first time that you've really highlighted that it's two different code sets. So I guess, could you clarify like what the differences between these two code sets, and under which circumstances you would use one or the other?

Hey Allen, it's Kevin. The only thing that's been published right now is that the separation of the code sets is along the lines of duration of where, we've not been allowed to talk about the amount of wear times. Compared to what we have today, a single code spans three days to 21 days. And within that code set there are four codes, a global code, patient hookup code, a technical component and a physician interpretation. Those same four code sets will be replicated twice in the new code set arrangement.

Got it. And then kind of like, I guess a broader question, hopefully if you can talk around it a bit. But – regardless of what the decision is, in terms of like the value of these codes. Can you walk us through kind of the rollout once we do hit January 2021, like how much time will it take for whatever price changes implemented to kind of really start impacting the business and what does that rollout look like along kind of the different mix, and a mix of consumers that you have? Thank you.

Sure. So this code set change affects our payment with CMS, which is about 26% or 27% of our revenue, that code change would go into effect in January of 2021, unless it were delayed for some reason or if it were appealed. Our expectation is that it would go into effect at that timeframe. And so whatever the decision is in the July timeframe to either accept or modify or to change the relative values that are being assigned here in the February the timeframe that will go into effect at that period of time.

Your next question is from David Lewis. Your line is now open.

Good afternoon. This is [Jay Chado] on for David. Kevin, I had two quick questions and then a follow-up. I was wondering if you could talk about the underlying momentum in the business. If you look at guidance into the fourth quarter, it may be implies a little bit weaker quarter-over-quarter growth into the fourth. And in light of the full AT launch, I was wondering if you could talk about, how we should think about the incremental pull-through either AT or XT? Now the device is fully underway and then I had a quick follow-up for Matt.

Sure. Okay, I would start-off by saying from a momentum standpoint, I don't think we could be in a better off position right now. We have a large number of positive growth drivers. I think everyone understands and accepts that we're really well positioned competitively and got a very, very long runway ahead of us here. And growing salesforce, competitive differentiation, abundance of clinical evidence on, that's allowed us to raise our estimates throughout the year. I think relative to the fourth quarter here and looking forward, it's important to note that, changes in growth rates don't imply less opportunity or imply weaker execution, it really implies the segment that we're targeting is different now than the segment that we targeted in the past. And I like to think about it from the standpoint of when we study our opportunity funnel, we now are characterizing ourselves as having transitioned from let's call it early adopters, where those early adopters were in order to change their status quo were largely looking for a demonstrated clinical benefit. And we did that really well and we continue to do that well in terms of an unsurpassed assurance of accuracy, proven ability to change medical managements and the 30 plus peer review publications that we have, that show that we're superior. Today, I think we're more in the middle market, the middle majority of the market and there those customers are asking us not only for the clinical benefit, but they're asking for productivity gains, gains that help them to be world class in terms of delivering clinical, operational and financial value. And I said in our prepared remarks that we've got comparative customer data that confirms that we measure and diagnose patients in fewer – in less time with fewer unnecessary repeat tests with fewer resources and lower costs, that's what people want. And that takes a lot of energy for us to work with these large accounts in order to get them over the hurdle to change their status quo. Their overwork, their pressed for time and in order for them adopt they have to have, not only the proven clinical superiority, but the completeness of the platform. And so I like in our trajectory that we're on right now more related to the segment of the market that we're addressing, it's certainly as large and growing, but it's a little bit harder to tap because of the requirements that those customers have for us. I wouldn't read into it, I wouldn't read anything into it other than that. As far as XT and AT pull through, maybe Matt can address that. We continue to see very strong XT pull through and AT accounts. Matt, I think you said a few things on your prepared remarks, there maybe you want to go into that.

Yes. Well, I think that that's right, Kevin, before we dive into that everyone has to understand that the AT product is a completely different workflow and work. Our excitement of launching that product and the feedback we've gotten from the field has been outstanding and we've provided updates for I guess three quarters now on pull-through that we see in those pilot accounts. But again, those pilot accounts are extremely limited and we're just now starting to launch it. So I think there's going to be some learning curve here as we move into November, December as relates to providing change of our guidance around AT. So I think what I would strongly suggest is that we will continue to provide feedback as we move to this broader commercial opportunity around the XT pull through, particularly as it relates to new accounts or Greenfield accounts, I think that's going to have some interesting outcomes for us. So I'll just leave it that for now.

I have another question here?

Yes. You want to follow-up with me on another question?

Yes, thank you. And either for Matt or Kevin. As you think about the recent capital raise, how should we think about incremental investment into commercial infrastructure? Any potential adds into the fourth quarter or earlier in 2020 next year?

No, I don't think so. I think everything is maybe one small caveat, I think everything is exactly the same as we've talked about on the raise. We just highlighted, we've already spent about $5.5 million on Verily development, obviously a significant portion that was the initial milestone payment and that's certainly going to be a good portion of it. The other two areas that we talked about are consistent with where I think our thinking is now as we move into kind of the budget planning season, and that is the sales force expansion as well as some dollars related to international expansion. I think those are absolutely still front and center in our minds. I did mention that although it's not going to be material moving forward, the amount required for bad debt expense is probably going to go up slightly. I think we've guided in the past at 4%, that is probably leaning more towards 5%, maybe 5.5% as we're just seeing a significant increase in deductibles and an incremental amount owed by the patient that's coming with the environmental territory that we're presiding. And so other than that small adjustment, I think everything else is exactly as we laid it out with the follow-on.

Thank you.

Your next question is from Jason Mills from Canaccord Genuity. Your line is now open.

Hi, Kevin. Matt and Dan, thanks for the questions. I wanted to go follow up on a few metrics that seem to be important in the model. So you talked a lot about, Kevin on this call, the larger health networks and IBMs, in the past you’ve been under-penetrated and relative to the amount of the market that they preside over. Could you talk about sequentially your success in penetrating those – that particular account base. And how AT may help you in fourth quarter and 2020, not only vis-à-vis the sale of AT, but the XT pull-through. I think you alluded to it to some extent. But, is that one – I guess a follow-up to that question is, is that one potential area that could drive upside to your revised guidance? Is that an area that perhaps is underappreciated in terms of the growth potential near-term?

Hi Jason, this is Kevin. So maybe just make sure that I got all those. So our first one was relative to same-store, new store how did new store do in the quarter, Matt will cover that. AT upsize, I think the answer is yes, our XT upsize as well. I mean, the AT numbers are small number from starting, but nonetheless, I think the pull through is probably more significant than the actual AT volume. And then the other one was…

Yes. Jason, I think what you were going for is from our strategy of these large systems, what does that sizing compared to the overall market? And we have not, done a deep dive into that number since last quarter, but based upon guidance since new store, same store sales, the answer is exactly the same. And that is the overall opportunity in those accounts as it relates to our market penetration, it’s almost on par with the broader market. So however you guys are defining the market, whether it's $1 billion in three quarters or $2 billion with some of these add-on indications, whatever, 10% or 15% penetrated in the broader market, we're also still 10% or 15% penetrated in these large integrated systems. So again, we think that bodes extremely well for us moving forward. Does that help?

Yes, it does. That's exactly where I was going with that, Matt. Thank you. And then just a few other metrics. In the past you've talked about not yet seeing the peak level of your productivity level, you've added more ramps this year than you originally thought, perhaps that – some of the productivity gains, I'm just curious if your – I you at this point, been able to identify a peak productivity level per your increasing sales force.

Yes. Jason. I mean, good question. We weren't trying to hide that obviously with a quarter that didn't – doesn't see as much growth because of the summer, right. there was not a huge change to those numbers and that’s we weren't calling out a higher a productivity level at this time. I think the last one we've called out is about 2.5 million, although we have talked about the ability to pull that in. I think the genesis of the question and the genesis of the answer is that, I don't believe any of us in the room feel as though we've reached peak productivity. And I think with the onboarding of these large integrated systems and the potential volume that comes with them, clearly would indicate that we haven't reached peak productivity. I just don't think that we're ready to call out anything higher right now, given what Kevin just talked about in terms of the strategy, given the AT launch and given that, we're a quarter away from guidance on 2020. So long story short we're, we're still guiding that 2.5 million, but I don't think any of us feel that we've achieved the top of that threshold yet.

Thank you.

Jason. I might add to that and just say that, we've added 40 people a year for the last two years, that would imply that roughly 60% of our sales force is with us less than two full years, this year and last year. And Matt's peak productivity number is when people are with us three to four years.

Three to four. Correct.

So we feel like, we’ve got an opportunity to grow there, but that peak productivity number, that's peak of the peak productivity number is still rather elusive for us to define.

Okay. Understood. Thank you.

You bet.

I am showing no further question at this time. I would now like to turn the conference back to Kevin King, CEO for some closing remarks.

Great. Thanks everyone. Thank you for joining our third quarter earnings call. We look forward to updating you on our year-end results and outlook for next year on our fourth quarter earnings called early next year. Thanks very much.

Ladies and gentlemen, this concludes today's conference call. Thank you for your participation and have a wonderful day. You may all disconnect.
