Good afternoon. My name is Chantal and I'll be your conference operator today. At this time, I'd like to welcome everyone to the Penumbra’s Second Quarter 2016 Conference Call. [Operator Instructions]. Thank you. I would like to introduce Mr. Dan Wilson, Director and Head of Business Development, for Penumbra. Mr. Wilson, you may begin your conference.

Thank you, operator. And thank you all for joining us on today's call to discuss Penumbra's earnings release for the second quarter of 2016. A copy of the press release and financial tables which includes the GAAP to non-GAAP reconciliation can be viewed on our Investor Relations website. During the course of this conference call, the Company will make forward-looking statements pursuant to the Safe Harbor provisions of the Private Securities Litigation Reform Act of 1995, including statements regarding our financial performance, commercialization, clinical trials, regulatory status, quality, compliance and business trends. Actual results could differ materially from those stated or implied by our forward-looking statements due to certain risks and uncertainties including those referenced in our 10-Q for the quarter ended June 30, 2016, which will be filed with the SEC on August 9, 2016, as well as those described in our 10-K for the year ended December 31, 2015, which was filed with the SEC on March 8, 2016. As a result, we caution you against placing undue reliance on these forward-looking statements, and we encourage you to review our periodic filings with the SEC including the 10-Q and 10-K previously mentioned for a more complete discussion of these factors and other risks that may affect our future results or the market price of our stock.

And with that, I would like to turn over the call to Adam Elsesser, Penumbra's Chairman and CEO.

Thank you, Dan. I would like to welcome everyone to Penumbra's second quarter 2016 conference call. I’m joined today by Daniel Davis, President of North America; and Sri Kosaraju, Chief Financial Officer and Head of Strategy. I will start today's call with a few highlights. Our total revenues for the second quarter of 2016 were $65.1 million, compared to $42.3 million for the second quarter of 2015, an increase of 53.9% as reported. We achieved net income in the quarter of $0.2 million, compared to a net loss of $2.7 million for the same period last year. The strength of our performance was again broad-based across both, neuro and peripheral vascular. We will outline what contributed to our performance this quarter, as well as our views on a few unique attributes in the quarter. In addition, I will walk through recent announcements about our products which demonstrate our focus on driving innovation and market leadership. I will then hand it over to Sri to cover more details on the financials as well as an update to our annual revenue guidance. We continue to execute on our strategic plan for our neuro franchise. A few weeks ago at the annual meeting of the Society of NeuroInterventional Surgery or SNIS, we showcased our recently introduced ACE68 reperfusion catheter, the latest innovation of our complete stroke system. ACE68 represents the latest and most advanced stroke technology that we have ever introduced. The early feedback confirmed what we hope to see. Easier tracking of a large bore reperfusion catheter which leads to faster and more complete recanalization for stroke patients. At the end of my comments, I will share some further context for how we see this product and its potential differentiation. Also at the SNIS meeting, the data from the three 3D trial…

Thank you, Adam. For the second quarter ended June 30, 2016, our total revenues were $65.1 million, an increase of 53.9% reported, compared to the second quarter of 2015. The impact due to currency fluctuations did not have a material impact to our results, as such we will only be highlighting our recorded changes in our commentary today. Our geographic mix of sales in the quarter was 67.1% U.S. and 32.9% international. Neuro and peripheral vascular represented 69.7% and 30.3% of sales, respectively. Revenue from our neuro business grew to $45.4 million in the second quarter of 2016, from $34.4 million in the same period a year ago, an increase of 31.9% reported. Our growth in neuro continues to be driven by the growth in the ischemic stroke market as well as sales of our Penumbra System which includes ACE, ACE64 and now ACE68, which we introduced late in the second quarter. In the quarter, it’s worth highlighting, a few additional unique contributors to our neuro growth. In both nuero access and neuro embolization we benefitted from separate competitor recalls and in the quarter, we also introduced our SMART Coil in Japan. As it relates to the SMART Coil, we do not expect meaningful contributions in the second half of the year due to lengthy hospital consignment processes. More broadly, as we look forward to next quarter, we expect to see the impact from the summer, particularly in Europe as well as in schedule cases in the U.S. as well. Revenue from our peripheral vascular business grew to $19.7 million in the second quarter of 2016, from $7.9 million in the same period a year ago, an increase of 149.6% reported. We saw strong growth across both, peripheral thrombectomy and peripheral embolization. In the period, we benefited from the SIR…

Thank you, Sri. We're in a great position halfway through 2016. Our team has continued to execute at every level, engineering, production, quality and commercial. I am extremely proud of their efforts. However, as I have indicated in the past, it is essential to remember that past success does not automatically translate into future success. We have a great deal of work ahead of us on product development, on the continued ramping of our operations, and on competing in a highly competitive commercial environment. Accomplishing our goals will take true dedication and patience. It will take all of us at Penumbra working in sync to achieve these goals. I know that everyone at Penumbra is humbled by the importance of the work in front of us and deeply committed to doing it in a world-class manner, which will then translate to making a huge difference in the lives of so many patients and their families. Thank you. Operator, we can now open the call to questions.

[Operator Instructions] Your first question comes from the line of Mike Weinstein with JP Morgan. Your line is open.

Thank you, guys. Can you hear me okay?

Yes. Hi Mike.

Great. First off, congratulations on a fantastic quarter, obviously incredibly impressive performance. Adam, I was hoping you could spend a minute first on the peripheral vascular business. It's not often we see businesses grow 150% year-over-year, particularly when you have been out of for a few quarters now. So, can you -- number one, could you help shed some light on the growth in thrombectomy franchise versus the embolization franchise? Certainly both were very strong. But can you give any indication -- is thrombectomy basically driving it and embolization is getting pulled along or it really that there is two separate engines there? And then, can you talk about the comments you made about the momentum, post the SIR meeting? Was that because of the PRISM data on Indigo, what was the -- what really drove that momentum in the business that you saw over the last couple of months? Thanks.

Thank you, Mike. To sort of start with the first question around are they separate businesses, they are obviously separate product portfolios that have different process of working with our physician customers in various cases. However, there is some benefit that comes from being in the lab with our customers who are starting to learn and get experience with Indigo and some potential opportunities, if you will, or pull-through to use the vernacular that comes with that on our peripheral embolization. However, there are other situations where they really are separate in customers who have really started to learn the benefits of our coil, which is very unique in the peripheral space, have found that independently something that is impacting their choice in greater number of cases. To move to the SIR part of the question, it really wasn’t data-driven experience, albeit certainly the PRISM data is very positive for us. It was really the opportunity to engage with significant number of customers throughout the meeting whether it was in our booths, or symposiums, or talks, and really show them the benefit for really the first time around the Indigo system and the larger sizes of the Indigo system and what the possibilities of that could be. When we came out of that, we really started to focus on those physicians who had that experience and wanted to learn firsthand the benefit of the products in a variety of types of cases, both on the venous and the arterial side.

Okay. Adam, two follow-ups for you. So, one, with customer feedback now coming in on 68, can customers see the difference of the performance and the feel of 68 versus 64. What you are hearing on that? And then obviously 68 was great, 64 is even better, 68 sounds even better. Can they tell the difference. And then, second, you made a reference on the neuro access side of the business that you benefited from some competitor issues, and that maybe one-time. I just wanted to call that out a little bit more.

Sure. Let me start with the 68 question and then I can just at a high level address the access and ask Daniel Davis to maybe comment -- touch more on the access question. The 68 is without a doubt the best thing that we've ever launched. And the two things that we are hearing right away are the trackability of the catheter, it really tracks better than anything that we've ever launched of that general size; and second because it's larger and we have -- it comes with our new high-flow tubing, which the combination of those has allowed for cases to take a shorter and shorter time. And that's why I highlighted the idea or the fact that we've now had a number of reports of cases being done under five minutes, and I mean starting with the incision in the femoral artery tubing done, and that's just a such ever remarkable event or moment in time to be able to see that possibility. And that's all because of the fact that the catheter tracks much faster and therefore and also then aspirates more completely that much faster. And so, it's really a great moment. On access, it is less of specific product being substituted for a recalled product. It has to do with the larger, the recall that Cook [ph] is facing and how our access portfolio has benefitted more generically than on a sort of product by substitute product basis. I’ll let Daniel address that a little bit more.

Yes, thanks, Adam. As Adam pointed out that it's not directly the primary products we sell in access that really, really category effected by Cook. [Ph] But what it gave our sales force the opportunity to do was really engage with the customer than help them solve problems. And that is always the great thing in the field that the rest can be valuable to the customer and help them overcome an issues whether it'd be short-term or long-term. It really gave them unique opportunity to engage with the technology that we have, not just for those types of products but more importantly with our entire access portfolio in the nuero side.

Your next question comes from Bob Hopkins with Bank of America. Your line is open.

This is Travis Steed on for Bob. I appreciate it's early, but can you just share with us some of the feedback that you've had in the field since the 3D data were publish? And how are you thinking about the percentage of cases that use aspiration that changes and over what timeframe are we looking at?

Well, it's a good question and I think it's a little early for us to have any sort of definitive reaction or modeling around that. We don’t think ultimately it has a huge impact in any kind of near-term way. One, the 3D device itself won't be approved or cleared rather for some period of time; we haven’t submitted it yet. And second, we’re already in the majority of the cases whether it's in aspiration alone or in what I think is probably the larger segment of Solumbra users where it's a stent retriever plus aspiration. So, even if a customer or a physician were to be now intrigued by the idea that there is data that supports the use of aspiration alone, we wouldn’t see any benefit from that on a financial basis. Obviously, the case might go faster and there might be some benefit from the patient standpoint, but we’re already in most of those cases. So, it really is the group of patients -- rather the group of physicians who are using just the stent retriever without the assistance of direct aspiration. And it’s just way too early for us to comment on the impact that this data will have on those. I will tell you as a general comment that the overall reaction both at SNIS and in the week and a half or so since that meeting ended to the data and to the fact that there is now sort of clear proof about what we’ve always stated around aspiration, has been extraordinarily positive, and very, very supportive in the physician community. And again, one last reminder, that trial was done with two generations ago aspiration tools, so 64 and 68 were not used in that trial, and some of the much older technology was used. So, I think it really bodes well for the future, but I don’t think it will have an impact in the short term.

Great. That’s helpful. Can you help us understand some of the moving pieces? And assuming the new revenue guidance, you did over 50% revenue growth in the first half, only assuming low 20% in the second half, just trying to decipher how much of that is conservatism versus what you’re seeing in your business?

Hey, Travis, it’s Sri. So I’ll comment on that. So, we’re not going to qualify our guidance any further than we have. But just a couple of reiterations of the comments we made today. One, Q2 was an extraordinary quarter, if you look at it across both businesses. In our neuro business, we saw the highest sequential increase on a percent basis in a quarter than we’ve seen over the last eight quarters. So, extraordinary performance in that business. And on the peripheral side, as we are dealing with early quarters since the launch of CAT 6 and 8 last year with the venous indication, Q2 was our largest dollar sequential increase that we saw since the launch of those devices. So, it was an extraordinary quarter from many respects and we highlighted a few other areas as well where we saw benefit. If you couple that with the summer seasonality that we’ve typically seen, we’d expect that Q3 is a sequential decline to Q2. So, that is an important thing to understand in our guidance, but even despite that, if you look at the back half of the year, it’s sequentially up versus the front half of the year, as you think about the guidance that we laid out. So, we continue to feel strong about our business, we continue to feel it’s heading in the right direction. I highlighted the Q2 phenomena. And then, the last point I’ll make on that is regarding the comps. Our second half comps get tougher. We’ve talked about our neuro comps in prior calls, and I alluded to in my comments today, Q3, we take on a pretty sharp increase in a comparable related to what we saw in the launch of the larger sizes CAT 6 and 8, again that I talked about before. So, the last point is around a changing comp environment.

Your next question comes from Larry Biegelsen with Wells Fargo. Your line is open.

I just wanted to ask one clarifying question on the SMART Coil comments in the second half. Was that for Japan-only or worldwide? I think I heard you say Sri, you don’t expect meaningful revenue in the second half. It wasn’t clear if that was worldwide or Japan. And just could you -- while we are on SMART Coil, could you give us a little bit more color on how the launch is going? I mean until this point I think you have about 25% share of large aneurysms, and this gives you an opportunity to penetrate the smaller aneurysms, which are much larger portion of the market. So, it’ll be helpful to hear a little bit more on that and I had follow-up. Thanks.

Sure, thank Larry. So, I'll start with your first question and Adam will touch on your second one. As it relates to SMART, that was a broader global worldwide comment on SMART. And if you recall, in Japan, we have a distributor relationship. So, the introduction of SMART related to that relationship with our distributor was what we referred to in our comments. As we look at the back half of the year that’s in all global comment related to the U.S., Europe and Japan.

And then, Larry, as it relates to the question of the launch, if you remember, we have talked I think in the past coils, particularly neuro coils are consigned as a general matter. And so, there is a long process of getting consignments in the hospitals, particularly in the extremely competitive environment that we operate in, in the coil market. In addition, we are investing and scaling our production and that takes some time, and we’ve alluded to that as well because that is a real important point. We have to build up consignment inventory, which is obviously at a different scale than inventory just to be sold on a per use basis. And that just is taking kind of time that we have always indicated.

And then, I wanted to ask one on the ischemic stroke market. Can you talk about the growth momentum in the overall market in first half and how we should think about the second half? And I think you said in the U.S. in 2015, there were 16,000 to 17,000 cases, up from I think 12 or so thousand in 2014. We are modeling somewhere around same incremental growth in patients but slower percentage growth by 22,000 in 2016. Is that kind of is the market shaping up as expected? Any commentary on that would be helpful. Thank you.

Larry, the market is moving as we had expected. And I think the numbers that you mentioned are consistent with what we have talked about and kind of what we view. And so I think we would just confirm for you that the market’s moving at that growth rate and consistent with what we had expected. And I’ll let Adam touch on that little further.

Yes. I obviously agree with Sri’s comment about the growth of what we have talked about in the future. What I have highlighted in the past and I want to sort of comment again as we get more and more into this, the first year, really all of last year, we were hoping and seeing a lot of conversation around the market development but other than local work, not a lot of organized activity. At this past SNIS meeting, just a week and a half ago, the vast majority of the time spent, both on the podium, in the hallways, in the conversations, in the meetings that we had with the leadership that's all we talked about is the efforts that are going to be put in that are now underway politically on a state-by-state basis, on an economic basis, on a public relation basis. And there are number of those initiatives that are starting. They will take -- and in this, we are a 100% in agreement with our competitors, this will take a number of years, but the work is being done. And I can tell you it is incredibly heartening as somebody who’s been in this field for a long time to watch people embrace this work, get excited about doing this work. So, I do think we’ll see the growth continue. But, I think we have to wait and let some of these efforts take time and grow the fruit that we think they will grow in future years.

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

Let me follow-up on Larry’s questions just with respect to the market in your commentary about the initiatives going on, I guess a multi-part question. Could you talk about what work you may be doing with CMS, other insurers as it relates to market development? Would be understanding that from the CMS standpoint -- I think you talked about this in the past, after stroke care -- stroke management of patients that don’t reach the proper provider in times of significant cost burden and what sort of issues [ph] are put there, and what sort of impact you see to the broader market for interventional stroke I guess over the next couple of years? And then secondly, within ischemic stroke guidelines, guidelines from SNIS perspective are fairly generic but obviously, as you pointed out with AHA as mentioned of stent retrievers, it doesn’t intends on your access to the market. But it would seem given these data presented at SNIS that there may be motivation for those guidelines to change, maybe in your fit [ph] over time, be interested in your thoughts on that as well and I have a few quick follow-ups?

Okay. Well, great questions. Let’s start with sort of the political work and then, I'll touch briefly on the reimbursement. The real work, as we see it, has to happen sort of politically. The SNIS society has taken on the effort as a physician society around going after several states to see if they can put in a model at the state level to ensure that the right patient gets to the right place. That's obviously incredibly exciting, it will take some time to have those kind of rule put into place. On a reimbursement level, just to remind you and everyone, reimbursement currently is quite good for stroke -- for mechanical thrombectomy. So, it’s less -- and the private payers have really sort of stepped up as well. So, it’s less an effort. I know there are some discussions at the society levels to try to realign or reincentivize some of the patient flow based on reimbursement, but way too early to sort of comment on that work that’s being done, and it’s certainly possible in the future. And then, to briefly address the question, I certainly am obviously very excited about the randomized data comparing stent retriever and direct aspiration versus just aspiration alone. And I certainly would assume that the AHA would be interested in that data. But, I obviously can’t comment on their process of updating the guidelines what have you. As you said, it hasn’t really had any impact whatsoever, but it’s I am sure matter of time.

That’s helpful. And then, back to your previous question, you commented about the data that randomized data, the fact that you’re in a majority of cases and therefore seeing conservatively and may be suggesting that there may not be a significant period [ph] changed. However, I am wondering if you could comment about the first line therapy mix that stands today versus may be when the original data sets were published [indiscernible] a year and a half ago. And help us understand the mix at that time and seemingly hasn’t changed much over the last year, stent retriever used alone was still a relatively large portion of the market, in our model close to 40%. So seemingly that is a part of the market that would be accessible if minds change over time. I am just wondering if these data have any medium term impact on migration and first line therapy mix in your mind.

It’s a hard -- again, week and a half after the data was released, so it’s hard to answer that question definitively. I will tell you that if physicians are using stent retrievers alone or with balloon guide rather,. they are pretty wedded to that technique as opposed to those who are using the combination. And to remind you, obviously it is a majority who are using either aspiration alone or in combination. That’s the first wave where people are going to be empowered, I think to try with their aspiration -- with our aspiration catheter to go without a stent retriever. But again, it’s hard to quantify that in any kind of short term basis just a week and a half or two weeks after the data is released. So, we’ll know over time but I don’t think we’re going to see a wild change in the short-term. Over time, we have always taken a position that we believe that the migration will continue. One, the data will continue to develop and second, when you can do a five-minute case and the cost effectiveness of that is going to be hard to argue with that over time.

And Jason, I know a couple of the questions have been trying to sort of translate this back to the model and the stroke model and numbers and just to comment and reiterate maybe some points Adam made to the numbers. I think we have all expected and modeled a steady move or march towards direct aspiration. And I think this data, I think as we view it solidifies that foundational view that we are moving that direction. I don’t think there is an immediate implication that mix drastically changes right now. From our perspective, it only supports it. And again, just to come back to the bigger point for us, the moves in those numbers are few points from moving folks who are using a stent retriever to Solumbra direct aspiration, while beneficial is no greater than the move of the market, and obviously that’s the bigger focus for us on top of all this.

Just one quick follow-up and I'll get back in queue, a lot of things going on here, so there are a lot of questions. With respect to aspiration, we get -- I am sure everyone on the call gets several questions about eventual competitiveness in direct aspiration. You guys have been at this for a while, but I guess the question is given the data, the trial that you invested in, what do you expect anybody that would seek to complete with ACE68, what kind of trial do you expect that they would need to run to secure not only FDA approval but the mindshare that you will have with these data to be comparable to these data? And do you or have you seen any activity in that area? Thanks for taking all the questions.

Yes, Jason, I really appreciate. Look, we have talked about it in past calls, you guys have asked these questions around competitive guide catheters that don't have an indication to revascularize stroke patients the way the Penumbra System does. And we expect that to continue. ACE68 really is such an extraordinary tool that we expect that on its face compete pretty handedly with those guide catheters. A company to get on label and have a system that has tubing and a pump, and just as a reminder our indication for the Penumbra System is a close one. You are not allowed to sort of piecemeal our products in usage. Obviously physicians aren’t liable to the FDA for doing that but they are becoming increasingly aware that if they're sort of breaking our system in pieces and using it in the wrong way or against our labeling rather, they could be liable to patients, obviously. And I think they are just being pretty careful now that we have really the preeminent aspiration tools, most physicians that I've heard of would not put their practices at risk that way. So, I think that's a pretty important tool aspect of this for them to get on label at least in the past. And again, I can't speak to what happens in the future. The FDA has been pretty clear that you would need to run a clinical trial to support your 510(k). And that trial would of course have to have their own aspiration source because you couldn’t use ours, and they would have to be non-inferior to an existingly-cleared product, so either a stent retriever or our aspiration system. And given the current success of them, be a pretty significant size trial.

There are no further questions at this time. I will now turn the call back over to Mr. Wilson.

Thank you, operator. On behalf of our management team, thank you all again for joining us today and for your interest in Penumbra. We look forward to updating you on our next call. Have a good day.

This concludes today's conference call. You may now disconnect.
