Thanks, Lynn. Good afternoon, and thank you for joining us. I'm pleased to welcome you to SI-BONE's second quarter 2019 earnings call. Before we get started, I'd like to announce that Laura Francis has been promoted and will now serve as both Chief Operating Officer and Chief Financial Officer for SI-BONE. Across these roles, she is responsible for finance, accounting, treasury, supply chain operations, quality, IT, facilities and human resources. During her time at SI-BONE, Laura has demonstrated exemplary leadership, integrity, problem-solving acumen and dedication. We look forward to her continued contributions. Turning to our business results. We made important progress during the second quarter. Total revenue was $16.3 million, growing 19% over 2018. U.S. revenue was $15 million, representing 24% growth over the same period last year. And international revenue for the quarter was $1.3 million. Our second quarter results demonstrated momentum as we expanded our commercial footprint for providing differentiated surgical devices in the sacropelvic space. This was particularly evident in the U.S. where we have seen accelerating growth since the end of 2018. We are starting to see the impact from growing payer coverage and sales force expansion. We expect further productivity gains in the back half of this year as our newer sales reps ramp toward full productivity. As a result of this momentum, we recently reached a very important milestone. iFuse has now been used in more than 40,000 procedures by more than 1,900 surgeons worldwide. This achievement confirms the growing attention and focus on sacroiliac joint dysfunction and its role in lower back pain as well as the joint's importance as part of our musculoskeletal system. It is gratifying that so many patients who have suffered for years are now able to regain [Technical difficulty] who become potential candidates for surgery, due to their…

Thanks, Jeff. I appreciate your confidence in me, and I'm excited to continue as the Chief Financial Officer of the company, while also overseeing the operations of the business. I'm fortunate to work with a fantastic team of people at SI-BONE, executives, managers and individual contributors, who are committed to our patients and surgeons, while also driving growth and success of the company. Let me now turn to the financial results. For the second quarter of 2019, revenue increased 19% to $16.3 million, compared to $13.7 million for the second quarter of 2018. U.S. revenue for the second quarter was $15 million, representing 24% growth over the same period of the prior year. The increase in revenue was primarily driven by an increase in domestic case volumes. International revenue for the second quarter was $1.3 million. As Jeff mentioned, international sales were constrained by open territories in Germany. Gross margin for the second quarter of 2019 was 90% compared to 91% in the corresponding prior year period. The slight decrease in gross margin was driven by an increase in personnel spending to support the growth of the business. This is in line with our expectations for gross margin to trend toward the mid-to-high 80% range over the next couple of years. Operating expenses increased 61% to $22.9 million for the second quarter of 2019, as compared to $14.2 million in the corresponding prior year period. The increase was primarily driven by higher surgeon education spending and increase in sales force hires and additional resources allocated to advertising and marketing. During the quarter, we increased our sales and marketing spend to capture the opportunity from positive and exclusive reimbursement decisions made by U.S. commercial payers. We also incurred higher general and administrative expenses due to higher stock compensation expenses and the ongoing costs associated with being a public company. The operating loss was $8.1 million in the second quarter of 2019 as compared to $1.7 million in the corresponding prior year period. Our net loss was $8.7 million or a loss of $0.35 per diluted share for the second quarter of 2019, as compared to $3.1 million or a loss of $0.87 per diluted share in the corresponding prior year period. We ended the second quarter with $108.5 million in cash and marketable securities. Turning to our outlook for 2019. We continue to expect revenue to be in the range of $65 million to $66.5 million, representing growth of 17% to 20% over full-year 2018. Due to the seasonality of the summer months, we expect revenue in the third quarter to be sequentially flat, compared to the second quarter and then accelerate in the fourth quarter. Outside of the U.S., we expect an improved second half growth rate with further improvement in 2020. I'll now turn the call back to Jeff for closing comments.

Thank you, Laura. In summary, we are encouraged by our growth in the U.S. Our U.S. sales hiring efforts are squarely on track, interest in the Bedrock technique continues to grow, and we are confident in our ability to improve our international performance over the coming quarters. You may have seen the save the date for our upcoming surgeon Q&A event on the morning of September 26 in Chicago in conjunction with the North American Spine Society meeting. At the event, we will be hosting a surgeon panel with Dr. Josh Heller from Jefferson; Dr. Andrew Kranenburg from Providence Medford Medical Center; Dr. David Polly from the University of Minnesota; and Dr. Timothy Holt from Montgomery Spine. Investors and analysts will have an opportunity to interact and ask questions of these leading surgeons, as well as our executive management, and we anticipate an insightful and productive morning. We look forward to providing updates on our progress and look forward to seeing some of you this week at the Canaccord Growth Conference in Boston. With that, we will now open it up to questions. Operator?

[Operator Instructions] Your first question comes from the line of David Lewis from Morgan Stanley. Your line is now open.

Good afternoon. Jeff, just a few questions for me. The first is just thinking about commercial expansion in the first half of the year. So, two things. One, the second half of the year, should we think about commercial expansion, rep and clinical support specialists similar to the first half or you slow down the pace of ads just given the traction you've had in the first half of the year? And in terms of – is it safe to assume for the U.S. market, we should be thinking about acceleration from the 2Q levels into the back half of the year? And then I have a couple of follow-ups.

Yes. So, David, on both those questions, so first of all, as I said, we're very much on track and we are highly confident that we'll get to that 102 to 112 range of total reps in the field. And there's a little doubt in my mind and Laura's mind that we're going to get there. We're going to continue to hire at a pretty strong pace in the back half, and Laura talked a little bit about the expenses – or can talk more about those expenses. But we're finding really good quality people. And we're a little bit ahead of where we expected to be. So, we feel very good about that. As to your question about accelerating revenue, as you know, we've gone sequentially in the U.S. from 16% growth to 19% growth to 24% growth. We certainly think that we can keep it in the 20s in the back half of 2019. I'm certainly not, at this point, going to promise you that we're going to take it north from 24%, but we're feeling very good about what's going on in the U.S. And for that matter, Europe has taken a little bit longer to get back on track. But we feel very good about what's going on in Europe and getting their growth there. If you've done the calculations on the number, you know that numbers – you know that we had some challenging growth, let's just say, in the second half of last year in Europe. And it's absolutely getting better although it's certainly not helping the overall picture yet. But when it does, I think with the U.S. doing really well and Europe back on track, the overall picture will look really quite good.

Okay. Very helpful. And then kind of two related reimbursement questions, one you kind of already addressed, but one is sort of on the physician side and one is on the third-party payer side. So, there are a couple of large third-party payers that are not yet – have not yet issued national coverage decisions. How important is the five-year data going to be in terms of swaying some of those larger payers? And the CPT code process, Jeff, on one hand, I say some of the language in the document on the proposal was encouraging and that they're still saying the code was undervalued yet they said that a year prior. So, how are you interpreting that relative language? Thank you so much.

Yes. So, on the large payers, David, the ones that we – the one that we've had the most interaction with is Cigna and they clearly said to us that the five-year data is very important to them, and we've gotten sort of positive signals there. So, I'm encouraged there. Last communication with Anthem and Aetna. Humana isn't quite as important in the sense that a lot of it is still government business. The schedule on those is Anthem is this fall. As I think you may know, Cigna and Aetna are scheduled on their annual reviews to be in early Q1. I think if the five-year data publishes, and it is in review right now at a journal and I know it's to the point where there's one more review needed on that. If that happens to publish a little bit earlier in the next couple of months, I think there's a chance that Cigna could flip prior to January. But I'm kind of counting and hoping that January is sort of the time frame there. So, those are the larger payers. And I do think five-year, in general, is important. And it all takes a little bit longer than we hope, but I think once we get over that hump, that will help the business overall. As to the CPT commentary, I think it is a little bit unusual – I should say, unusual for CMS to ask about specific commentary. So, I read it at least is encouraging that they want to hear from people as to why the code and they specifically set 20 RBUs – might actually go up to 20 RBUs and that was the proposal from one of the medical societies to make it at parity like there is parity in certain other medical procedures. I know for a fact that there are a lot of comments that have already been sent in to CMS from surgeons who have written them their own original commentary on why the procedures should be paid more from a time intensity, compared to other surgery. So, I think there was a groundswell of people pushing on the issue, as well as medical societies. These things, as I think we all know, are difficult to handicap, but there's clearly an opening and I don't think we'll know what the result is till the first week or so of November.

Right now, what we're assuming, David, is that it stays the same and we feel very comfortable and confident that we can build and grow the business with where the surgeon payment currently is at. But there's definitely a lot of activities around trying to make a change to that before the end of the year.

Great. Thanks, so much guys.

You’re welcome.

Thank you.

And we have a question from the line of Kyle Pezzi from Bank of America. Your line is now open.

Hi. This is actually Travis Steed and I'm here for Bob Hopkins.

Hi, Travis.

One quick housekeeping question. Wanted to see it, if Bedrock contributed any revenue this quarter? And also, what you're assuming for Bedrock in your full year outlook?

It certainly did contribute revenue. I wouldn't say that in the big picture was overly meaningful. There were a fair amount of surgeries done with Bedrock across quite a number of academic institutions, and I'm reluctant to sort of say exactly how many at this point because we don't want to be tracked on every single Bedrock number. But suffice it to say that we're very encouraged. And if you look at the presentation, the corporate presentation that has posted or is about to be posted or I will make tomorrow when I speak publicly at this conference, you can see that there have been – there was a June large session on Bedrock attended by many academic surgeons in the U.S. There was a second Bedrock big symposium where there were, I think, 6 or 7 presentations from major surgeons in June. So, there was one in May, one in June and then in July, so three months in a row, there have been presentations. And that July 1 was in Amsterdam, as I mentioned, at IMAST. And so, the interest level is very good. And I have heard, for instance, Dr. Polly was at I think at least two of those three where he is getting calls from surgeons and said, I want to learn more about this, I'm hearing about this. And then at NASS coming up in Chicago, there are three sessions on Bedrock. One is an actual surgeon training, there's a Bedrock educational summit dinner, and then third, there's an official mass program on pelvic fixation and the question is where are we now and that entire session is focused on Bedrock. So, really encouraging interest. What we had hoped for as to revenue in the back half, I think probably we're going to punt on that question at the moment.

Yes, our primary focus there, Travis, as you know, is really getting the halo effect of Bedrock with the key opinion leaders and the focus on the SI joint, and that's exactly what we're getting from Bedrock. So, we're pleased with that. And for right now, revenue is a secondary consideration.

That makes sense. And on the Bedrock, you've talked about 25,000 cases in total per year. Just trying to think over the next couple of years, you think you can penetrate 1% or 5% or 10% of these. It seems like you could – there's less friction with that versus your core product and just seems like it can move faster. Just want to get a sense for how you're thinking about that over the next 2 to 3 years.

I think it's fair to say that it's well under – there's no diagnosis involved. There's – because it's more preventative. It's a well-understood problem that needs to be addressed. And so, there is no friction or question on those two subjects. And I think it's going to be – what we're seeing is it's a pretty, pretty – not easy procedure, but it's not that difficult a procedure to actually add on reasonably rapidly at the end of these long adult deformity cases. So, there isn't a lot of – I'll put it this way, I have not heard one surgeon say that makes no sense.

But Travis, what we're primarily doing is we really just launched the product in June of this year. We had some market preference testing going on earlier in the year, just launched in June in the U.S., have not launched yet in Europe and so it's very early days. And I think what we'd really like to do is see how the product performs over the remainder of 2019 and probably more directly answer the question that you're asking as we start thinking about guidance for 2020.

Okay. That’s helpful. Thank you.

You’re welcome.

I am showing no further questions at this time. I would now like to turn the conference back to CEO, Jeff Dunn.

Okay. In closing, we remain confident that our fundamentals are intact and we're well positioned to execute on our strategy. We look forward to updating all of you on future calls. Thanks, again, for your time today. And with that, we'll close up the call. Goodbye.

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