Thanks, Matt. Good afternoon, and thank you for joining us. Before I cover our third quarter results, I want to share some exciting news on the reimbursement front. A few weeks ago, we announced that UnitedHealthcare, the largest commercial payer in the U.S. with over 45 million members, transitioned to an exclusive iFuse-only coverage policy for minimally invasive SI joint fusion effective October 1st. With this updated policy requiring the use of iFuse for minimally invasive SI joint fusion, UnitedHealthcare joins more than 35 other health plans, including Anthem, Humana, and many Blue Cross Blue Shield Association health plans that collectively cover approximately 160 million people, the majority of the commercially covered population. With near-universal coverage for our procedure in the U.S., reimbursement provides a strong tailwind as we look toward 2022 and beyond. Now onto the quarter. I'm pleased to report that SI-BONE had a record revenue quarter as our employees continued to execute relentlessly through this unique operating environment. In the third quarter, we generated revenues of $22.3 million, representing growth of 9% compared to the third quarter of 2020. It's important to point out that the third quarter 2021 was negatively impacted by COVID deferrals while the third quarter of 2020 benefited from COVID rescheduling. Additionally, our sequential growth in the third quarter, while moderated by the surge in Delta variant hospitalizations, highlights the growing demand for our products and solutions. Let me discuss the impact of the Delta variant on our U.S. operations in the third quarter. We had strong operating momentum through early August when the elected procedure volumes were disrupted as hospitals prioritized resources to deal with the spike in Delta cases. The impact, which was regional, started in Texas and Florida and then extended to other regions. We believe that we were able to better manage through Delta than many of our peers based upon the demand for our products and excellent execution by our field team. We're also well positioned because approximately 80% of our procedures are performed in an outpatient setting or at an ASC; as such, in regions impacted by the Delta surge, many of our surgeons were able to move procedures to non-impacted sites of service. According to our booking records, Delta resulted in approximately 160 U.S. cases being deferred in the third quarter, representing approximately $1.4 million in revenue. The deferrals were almost evenly split between August and September. To put the impact in context, in the fourth quarter of 2020, we estimated a $1.25 million revenue impact from deferred cases. While these are cases we know to be deferred, we believe the impact of Delta was higher when accounting for potential cases that were not scheduled. Based on our experience from prior COVID surges, as infection and hospitalization rates decline, we believe we'll recapture the previously deferred cases over the next few months. As we enter the fourth quarter, we're encouraged by the continuing decline in new infections, fewer deferrals, and the growing surge in case backlog. Approximately 35 cases were deferred in October, a significant decline from what we saw in August and September, indicating progress toward a more normalized operating environment. The resiliency of our third quarter results reaffirms that our investments in growth initiatives over the last year are delivering and have positioned us to be a much stronger company as we emerge from the pandemic. Now, let me provide you an update on these initiatives as we look to extend our leadership position and drive durable long-term growth. Starting with sales infrastructure expansion, at the end of the quarter, our 135-person sales organization was comprised of 78 territory managers and 57 core clinical support specialists. We continue to target ending the year with approximately 85 territory managers and 65 clinical support specialists. Moving on to surgeon engagement, similar to procedure cancellation trends due to Delta, total active surgeons increased sequentially through August to an all-time high but declined in September to approximately 630 surgeons. When segmenting our surgeon data, the sequential decline experienced in September was primarily due to deferral of inpatient procedures, including adult deformity cases. As of October, we saw our recovery and active surgeons above June levels. Our simulator technology continues to remain a cornerstone of our surgeon training program, which was highlighted once again during the recent surge in COVID cases. In addition to efficiently training surgeons, the simulators allowed us to re-engage inactive surgeons and also serve as an effective sales engagement tool. Specifically, over half of the surgeons trained in the third quarter were trained using the simulator. While still early days, we're excited about the steady growth and adoption by surgeons trained on the platform. As part of our long-term strategy to grow our active surgeon base, we're investing in academic programs to educate residents and fellows on primary SI joint diagnosis and treatment. Since inception of the program, we've taught approximately 150 academic programs in the U.S., resulting in the training of approximately 800 surgical residents and fellows. Based on our experience, engaging fellows and residents at academic centers can accelerate the conversion to active surgeon once they begin practicing. In the third quarter, more than half of the training events were with new academic centers, demonstrating the growing interest in these programs. Finally, on our patient awareness initiative, in the third quarter, we methodically accelerated our investment in targeted digital marketing initiatives to educate and empower patients as they manage through their SI journey. We've increased our investments in search and social media, as well as added initiatives in display and native digital marketing to reach the large population of patients who are in chronic debilitating pain due to SI joint dysfunction or degeneration. We estimate that there are approximately 1.4 million of these patients in the U.S., many of whom are currently being treated with opioids and multiple steroid injections per year. Our digital initiatives will allow us to be data-driven, technology-enabled, measurable, and allow for continuous improvement in our marketing. We expect to see the revenue impact from these programs beginning in 2022. With that, I'll now turn the call over to Anshul to provide more detail on our financial results.

Thanks, Laura. Good afternoon, everyone. Our third quarter total revenue was $22.3 million, representing growth of 9% compared to the prior year period. U.S. revenue was $20.4 million, increasing 8% compared to the prior year period. International revenue was $1.9 million, increasing 31% compared to the prior year period. Even with the Delta headwinds in the quarter, on a sequential basis, total revenue did grow compared to the second quarter of 2021, which we believe demonstrates the strength and durability of our business. It is important to point out that the third quarter of 2020 was a different operating environment compared to the third quarter of 2021, making for a difficult comparison. Specifically, during the third quarter of 2020, we were benefiting from rescheduled cases canceled due to COVID during the first and second quarter of 2020, whereas in the third quarter of 2021, elective procedure volumes were significantly disrupted by the spike in Delta cases. Comparing our performance to the third quarter of 2019, worldwide revenue grew 38%, with U.S. revenue increasing 37% and international revenue growing 43%. Gross margin for the third quarter of 2021 was 89% compared to 87% in the prior year period as lower inventory write-downs more than offset higher costs of operations to support the growth of the business. Gross margin in the third quarter of 2020 was impacted by increased write-downs of iFuse-related inventory because of faster than anticipated adoption of iFuse-3D. Operating expenses increased 25% to $33 million in the third quarter of 2021 as compared to $26.5 million in the prior year period. The increase was driven by higher sales and marketing cost related to increased sales hiring, research and development expenses for new product, and increased stock-based compensation expense. The third quarter 2020 operating expenses were lowered due to preemptive steps taken in response to COVID-19 to reduce discretionary spending. Our net loss was $15.9 million or $0.48 per diluted share for the third quarter of 2021 as compared to a net loss of $9.5 million or $0.33 per diluted share in the prior year period. Net loss included $1.8 million in debt extinguishment cost as part of our refinancing in the quarter. As of the end of the quarter, our cash and marketable securities were approximately $160 million and long-term borrowings were approximately $35 million. Given our strong operating performance and solid financial profile, in August, we refinanced our outstanding debt and replaced it with a new $35 million term loan with Silicon Valley Bank at more attractive terms. As part of the refinancing, we reduced our debt balance by $5 million. Moving to guidance, our performance in the third quarter gives us confidence in the strong demand for our procedures. We do remain cognizant of the near-term uncertainty surrounding the severity and duration of COVID-19 and the potential implications for elective procedures and healthcare infrastructure. Based on the impact of COVID-19 on elective procedures, in the third quarter and into October, we are updating the full-year 2021 total revenue guidance to be approximately $89 million to $90 million, representing growth of 21% to 23% compared to full year 2020. I will now turn the call over for questions.

Thank you. Our first question comes from Brandon Folkes with Cantor Fitzgerald. You may proceed with your question.

All right. Thanks for taking my questions and congratulations on the quarter in a tough environment.

Hi, Brandon.

And just maybe – hi. Can you just elaborate maybe a little bit on some of the pushers and pulls on net revenue guidance? Obviously, it's quite a tight range. But that said, just any color in terms of what you're seeing now in the market? Have you sort of assumed a status quo through the end of the year? So, just any color there. And then maybe just some update on iFuse at all, just any color on the adoption there. Thank you.

Great. Thanks, Brandon. So our guidance does reflect a step up sequentially between Q3 and Q4. And as we mentioned, we did give quite a bit of detail in our prepared remarks in terms of what we saw in terms of cancellations. And as I mentioned, the operating environment in October – and October did continue to improve, but we also recorded approximately 35 additional deferrals there around $300,000 in cases in total. So, the factor which is harder to quantify is the impact of unscheduled surgeries as patients or surgeons or hospitals delayed treatment due to Delta. So the way that we're looking at this is that we're viewing October as the stabilizing month and our expectation is for November and December to continue to improve. But our guidance does assume some impact from Delta through the fourth quarter given the number of lingering macro constraints that are out there. And then we've also modeled some prolonged recapture into with the third quarter deferrals and into the fourth quarter, which is historically the busiest time of the year for us. So, we've incorporated all those factors into our guidance that gets us to the 89 million to 90 million for this year, growth of 21% to 23%, which implies revenue for the quarter of $24 million to $25 million. And just to reaffirm, as we look past COVID, we really do feel that the business is set up extremely well. Even in this environment, you can see us growing between Q2 and Q3 in terms of sales, growing once again sequentially for Q4 is our expectation based upon our guidance. And we think that's coming from new products that are driving growth and adoption, our expanding surgeon base, talented and growing sales force, and fantastic reimbursement. So it really puts us into a strong position as we look at 2022 and beyond. Now, in terms of TORQ while it's only been two quarters since the full launch, we're quite pleased with the strong performance of TORQ across trauma and competitive conversions. We see it as a great addition to our portfolio with iFuse-3D, which is the gold standard for SI joint fusion. And then we also have our iFuse Bedrock technique for adult deformity. Those solutions really provide us with a leadership position in the sacropelvic surgical solution space.

Great. Thank you very much. I appreciate all that. It's very helpful.

Thanks, Brandon.

Thank you. Our next question comes from Drew Ranieri with Morgan Stanley. You may proceed with your question.

Hi, thanks for taking the question. Just a little longer – I mean, you're growing above 20% from your guidance for 2020, but how should investors think about 2022? You're going to be entering the year with a bigger sales force, essentially universal coverage, better reimbursement. But just any high-level thoughts about headwinds or tailwinds as – we should be thinking about for 2022? And do you consider yourselves to still be a 20% plus top-line grower? Thank you.

Thanks Drew. At a macro level, we're encouraged by the improvement in the operating environment since September and we continue to see strong new case volume growth, but cancellations in October just remind us that Delta is still there and makes things somewhat unpredictable in the near term. Since we're dealing with a lot of macro uncertainty, we really don't think it's prudent to make comments or provide any official 2022 guidance at this time, but again we feel very confident in our long-term potential. We're aggressively investing in our differentiated product development strategy, our commercial infrastructure and we think that we can drive strong growth in the years to come. And so, that's really how we're thinking about things at this point in time and we'll obviously provide more information on our next earnings call.

All right, understood. And just with some of the reimbursement and coverage changes recently with United, can you talk more about any initial feedback you're seeing from the sales force as an opportunity to reengage surgeons that have maybe been on the sidelines since there wasn't necessarily the best coverage there? And then just what other opportunities you have to get more exclusive arrangements over the next 6 to 12 months? Thanks for taking the questions.

Thanks Drew. There are really two very recent changes in reimbursement that were major developments. So, you mentioned specifically UnitedHealthcare, which is the largest commercial payer in the country with over 45 million covered lives. And they're transitioning to covering SI joint fusion procedures only when using iFuse was a huge win for us. It just once again validates the clinical evidence that supports iFuse as the gold standard for SI joint fusion. And we also had that coming on the heels of the Anthem exclusive in July and Anthem was not covering previously. And so, the UnitedHealthcare decision was one of going from a general policy to an exclusive policy. Anthem was non-coverage to coverage, and not just coverage, but exclusive coverage. Based upon those two things alone, we now have 160 million exclusive covered lives in the United States. So, how do we think about things immediately and how do we think about things going forward? Since we have received the exclusives from Anthem and United, our sales and marketing teams have been reaching out to thousands of surgeons to educate them on these changes. In the case of Anthem, we've reached out to patients who were previously denied and we've been working with them to help them get the procedure covered. And so, there are a lot of marketing activities around these changes to make sure that surgeons are aware and those that were inactive because of coverage challenges we're focusing on those surgeons, but then also on approximately 6,000 surgeons who have yet to be trained and treat a patient. And so, it does provide a tremendous tailwind to us going into 2022. It also provides a strong competitive moat as well because we do know that both of those payers are enforcing the exclusive policies.

Thank you. Our next question comes from Craig Bijou with Bank of America. You may proceed with your question.

Good afternoon. Thanks for taking the questions.

Hi, Craig.

Hi, Laura. Let me start with – and I know you talked about some of the headwinds, COVID headwinds that you could potentially see in Q4 or have thus far, and still may see. But wanted to get your thoughts on what you're seeing from a hospital staffing shortage? And I know since your outpatient ASC based, or the majority is outpatient ASC, it seems to be less of an issue at least listening to some of the other companies that have reported, but would just love your thoughts on what you're seeing and if you see that impacting procedure volume during the quarter.

Yes. Yes, it's a good question. And we – as we mentioned, I'm really pleased with the execution of the team in the third quarter. I think that to – not to underestimate the amount of effort that went into continuing to grow between the second quarter and the third quarter, and continuing to grow sequentially into the fourth quarter. I really do think say a lot about the execution of our field team. But I would also say that we are less impacted by some of the staffing shortage issues that are out there since around 80% of our procedures are performed in an outpatient or ASC, but we're – as you can see from the cancellations and delays that we talked about, we're definitely not immune to those or to the impact of staffing shortages in the OR. We've heard anecdotally that we're aware that some surgeons are building backlogs. I heard numbers from three to four months of cases due to capacity issues. And so, assuming that hospitals are able to iron out those issues over the next few months, it should represent an additional opportunity for growth in 2022.

Got it. And maybe a quick follow up on that. You guys have bounced back relatively quickly in prior COVID waves. So – and I guess to the extent that that I know you talked a little bit about what you expect for Q4, but do you expect to see a similar bounce back as kind of what you've seen previously and I guess the second part of that is related to the staffing shortages. Does – do the staffing shortages create a bit of an issue to work through that backlog because that backlog seems a little bit longer than what you might have seen in previous waves?

Yes. I mean, I would say once again that we actually feel quite good about the momentum in the business and just seeing before the deferrals in the third quarter where our bookings would have been gives us a lot of confidence in the business going forward. But while we continue to experience an improvement in the operating guidance – environment, our guidance did assume some impact from Delta in the fourth quarter and we even gave the numbers for October. And it does show that you have lingering macro effects and constraints that are currently out there. So we have actually modeled a longer than normal recapture curve for the third quarter deferrals even though the fourth quarter is historically already the busiest time of the year for our surgeons, but that could also represent some upside for us if we're able to more rapidly recapture those deferred cases.

Great. That's helpful. Thanks, guys.

Thanks Craig.

Thank you. Our next question comes from Kyle Rose with Canaccord. You may proceed with your question.

Great. I'm going to try this second time here. Hopefully you can hear me all right.

Hi, Kyle. Yes.

Hi, good afternoon or good evening. So, yes, a lot’s been asked, the one thing I just wanted to ask was just some of the dynamics on the active accounts. I understand obviously, the accounts are down, you had some headwinds in the quarter just around everything Delta related. But you also have some big tailwinds when I think about Anthem, you've got United flipping positive or United flipping exclusive. And you're talking about using the simulators to bring back some of the – I guess, dormant accounts, maybe just help us understand what we're not seeing from the active account base and just what’s really happening out there as far as when the Delta and the COVID headwinds fade away, we see a strong bounce back in accounts. I’m just trying to understand what’s really happening below the surface there with your sales team?

Yes. I think you actually kind of hit some of the high points already. So when we were looking at our active surgeon numbers in July and in August, we were hitting all-time highs on those active surgeon numbers. And then we had a drop in September and we really dug into what was going on with our active surgeons. And what we noticed is that they were attributable to typical inpatient procedures and they included adult deformity procedures. And when we think about the bounce back in active surgeons in October, which went back to above our levels that we were at in June. There were likely a couple of factors that Delta had a transient impact on the inpatient hospital-based surgeons, including those who are performing Bedrock lawn construct procedures. So if things open up, these surgeons are resuming their procedures. And then also the fourth quarter is seasonally a strong period for procedures because patients have met their deductibles and their pent-up demand from the patient as well as the backlog. And that’s before you even think about the potential for rescheduled cases. So we certainly expect to see those numbers continue to hit all-time highs by the end of the year.

Okay, great. And then maybe just some of the early conversations your sales force has had with some of those your dormant accounts or accounts that were previous customers, and for whatever reason, whether it’s insurance coverage or not, are no longer users, maybe just how does that re-engagement with the physician? How does that productivity curve of the physician change relative to just to de novo or a new customer?

Yes. The inactives that move to active typically take less time because you’re not necessarily convincing them of prevalence. They understand the diagnosis already. In fact, they’re usually just getting a refresher on the procedure. With that said, they do have to start regularly diagnosing patients once again. And so, let’s say that a completely new surgeon is going to take 12 months to really get to regularly diagnosing and treating patients, whereas inactive to active surgeon is more in the six-month range. So it’s on the lower end of that.

Okay, great. Thank you for taking the questions.

Thanks, Kyle.

Thank you. And I’m not showing any further questions at this time. I would now like to turn the call back over to Laura Francis for any further remarks.

Thanks. So thanks to all of you for joining the call today. The performance in the quarter reaffirms the underlying demand for our solutions that it’s growing. And it gives me confidence in our ability to drive strong growth in 2022 and beyond. We have a multi-billion dollar market opportunity to penetrate here in the sacropelvic space. And we’re looking forward to the days to come. Thanks, everyone. Good-bye.

Thank you. This concludes today’s conference call. Thank you for participating. You may now disconnect.
