Good day, ladies and gentlemen, and welcome to the NuVasive fourth quarter and full year 2021 earnings conference call. I would now like to introduce your host for today's call, Ms. Juliet Cunningham, Vice President of Investor Relations at NuVasive. Please go ahead, Ms. Cunningham. You may begin. Thank you. Good afternoon, everyone. Joining me today are Chris Barry, Chief Executive Officer, and Matt Harbaugh, Chief Financial Officer. Chris will provide an overview of NuVasive's fourth quarter and full year 2021 business results and trends, and Matt will review our detailed financial results and our 2022 financial guidance. We'll host a question and answer session. The earnings release, which we issued earlier this afternoon, is posted on the IR section of our website and has been filed on Form 8-K with the SEC. We have also posted supplemental financial information on our IR website. As a reminder, this call is being recorded and an archive will be available on our IR site later today. Before we get started, I'd like to remind you that our comments during this call will include forward-looking statements which are based on current expectations and involve risks and uncertainties, assumptions and other factors, which if they do materialize or prove to be correct, could cause actual results to differ materially from those expressed or implied by such forward-looking statements. The factors that could cause actual results to differ materially are described in NuVasive's news release and periodic filings with the SEC. Except as required by law, we assume no obligation to update any forward-looking statements or information which speak as of their respective date. In addition, this call will include certain non-GAAP financial measures. Reconciliations of these measures to the most directly comparable GAAP financial measures are included in today's earnings release and in the supplemental information, both of which are accessible from the IR section of NuVasive's website. Now I'd like to introduce Chris Barry. Thank you, Juliet, and good afternoon, everyone. Earlier today, we reported our fourth quarter and full year 2021 financial results. On today's call, I'll provide an overview of 2021 and why I'm excited about 2022, including product innovation updates and our commercial progress to deliver growth and shareholder value. Matt will share additional details on the fourth quarter and full year 2021 performance as well as 2022 financial guidance. Our progress during the fourth quarter and in 2021 reflects how our market leading product portfolio and new product introductions are advancing the company strategy. I'm excited about how our investments over the past 3 years have positioned us to accelerate growth in 2022 and beyond. For the full year, our 2021 net sales came in at $1.139 billion, an increase of 8.4% on a reported basis, or 8.1% on a constant currency basis compared to the prior year. In a challenging environment, we grew our U.S. spinal hardware and U.S. surgical support business lines and delivered strong performance in our international business. Specifically, our core spine business in Asia Pacific, Europe, and Latin America delivered double-digit growth for the year, which reflects our progress to globalize our business in key strategic markets. As I've shared before, we have multiple vectors to drive growth, and during the fourth quarter, you saw us make progress on our strategy to extend our leadership position in less invasive surgery, take share in sub-segments where we historically had underrepresented market share, deliver differentiated innovation in enabling technology, and grow our international business. In less invasive spine surgery, we have continued to invest into comprehensive, procedurally integrated solutions that provide surgeons the flexibility to treat any patient pathology with any procedural offering, all from NuVasive. Our clinically validated solutions help address the anterior and posterior column from a lateral or prone position. We are well positioned to extend our market leadership in the $900 million anterior and $1.6 billion posterior spine sub-segments. In support of XLIF, the industry's only lateral procedure proven with 15 years of clinical evidence, we're excited about Modulus XLIF, our next generation expandable interbody for lateral spine surgery. This expandable interbody is manufactured with the latest technology from our advanced material science, research and development team, and we'll begin clinical evaluations in 2022. A key focus area within our X360 portfolio for single-position lateral surgery is our XALIF procedure. We've seen continued growth from XALIF through increased access surgeon training and new product introductions, including Modulus ALIF, and we are now the market leader in ALIF. We also expect growth from our TLIF portfolio, and we're expanding our offerings in 2022 to feature new technologies. MOD-EX PL, our next generation expandable interbody for posterior lumbar procedures, will begin clinical evaluations in 2022. The NuVasive Tube System, a tubular retractor system designed to support less invasive posterior decompression and fusion procedures, is scheduled to launch in the second half of 2022. These technologies help extend our market-leading TLIF portfolio. Our investments deliver growth in the $2.6 billion cervical sub-segment paid off in 2021. Our C360 portfolio delivered double-digit growth in both the fourth quarter and full year 2021, led by the NuVasive Simplify Cervical Disc and the NuVasive anterior column plating system. The Simplify Cervical Disc has been well received by our surgeon partners, and I'm pleased to announce we exceeded our initial expectations for net sales in 2021. With the Simplify Cervical Disc now integrated into our supply chain, we've expanded capacity and expect future growth for this highly differentiated technology. Our investments to create a world-class manufacturing facility have provided a unique capability to integrate current and future technologies into our global operations. We received initial FDA PMA approval to move Simplify manufacturing to our Ohio facility, and we have additional PMA approvals needed for assembly and packaging, which we expect in late 2022. To further extend our cervical portfolio, we expect to launch Reliant Cervical, our next generation posterior cervical fixation system in the third quarter of 2022. Reliant Cervical builds off the Reline fixation system, one of spine's most comprehensive fixation systems on the market, offering procedural versatility and compatibility with the Pulse platform. With our ACP system, Simplify Disc and Reliant Cervical, we anticipate continued strong performance from the industry's most innovative cervical portfolio. Moving to enabling technology. The Pulse platform continues to achieve key milestones following its commercial launch in the third quarter of 2021. With customer sites up and running across the United States and our first European commercial contracts received in the first quarter of 2022, hospitals and surgeon partners see the unique value of Pulse's software ecosystem that integrates multiple hardware technologies into a single platform. Pulse's seamless workflow provides surgeons the ability to utilize multiple technologies in a single procedure, providing utility in 100% of spine surgery cases, and helping to deliver improved operational, financial, and clinical outcomes. Operationally, the Pulse platform is a single unit of capital equipment with two fixed screens, wireless device connectivity, and multiple integrated software technologies. The reduced footprint in the operating room provides increased efficiency for the surgeon and staff. Financially, Pulse's extensible nature maximizes the hospital's investment. Through an initial purchase, providers can add future surgical applications from NuVasive and third-party partners that will integrate with the platform. Clinically, our internal testing shows navigation accuracy error rates are significantly lower than other leading navigation systems on the market. Our R&D teams are completing the next system-level software release for the Pulse platform, launching in the second quarter of 2022. The upcoming software release will include further integration with Siemens Healthineers' Cios Spin 3D mobile C-arm and additional capabilities to improve remote system upgrades in support of customer go live efforts. Pulse increases the procedural value across our entire spine portfolio. The value proposition of the platform is reflected in the growing global commercial pipeline in the United States, Europe, and Asia Pacific. As the XLIF procedure defined much of our past success, the Pulse platform will help redefine who we are today and has the potential to change the future of spine care. International continues to be a significant growth contributor for the company through disciplined commercial operations and execution. We expect to see continued growth from our international core spine business in 2022, led by our teams in Europe, Japan, and Asia Pacific, as well as from our NuVasive Specialized Orthopedics portfolio, which we are continuing to return to market in key geographies. As we grow globally, we know that we must be mindful of the impact we have on the world around us. To support our social responsibility efforts, we recently published the company's first environmental, social, and governance report, which outlines our commitment to make a difference around the world. In our ESG report, we discuss our mission to manage our business ethically and responsibly, and the many actions we've taken to keep our employees safe and healthy, minimize our environmental impact, and give back to our communities. We recognize we have more work to do, and we will continue to lay the foundation to advance our sustainability efforts. In closing, I believe we are well-positioned to win. When I joined the company three years ago, we were primarily focused on a single sub-segment of spine. We are now set up with multiple vectors of growth and possess the industry's most comprehensive portfolio of procedurally integrated solutions. We've evolved as a company and our evolution will continue in 2022 and beyond as we help define the future of spine surgery. We have made purposeful investments to ensure that our portfolio is highly differentiated in anterior, posterior, and cervical spine surgery and further complemented by enabling technology. Our R&D, marketing, and commercial efforts are aligned to target sub-segments where we have historically been underrepresented. Our R&D pipeline reflects an increasing shift towards software-related and breakthrough innovation. Our commercial organization has the leadership and infrastructure in place to increase customer density. I'm proud of our company's response through another challenging year. While we can't control the macro environment, as the potential future impact of COVID-19 continues to be unknown, we can control how we lead our organization through these critical times. To that end, I believe our strategic plan and investments are paying off through the successful market response to the C360 portfolio, growing utilization and commercial pipeline of the Pulse platform, and best-in-class product introductions in 2022 across each spine sub-segment. We remain focused on executing on our strategic plan to deliver growth and shareholder value in 2022 and for years to come. Now I'll turn the call over to Matt. Thanks, Chris, and good afternoon, everyone. Today, I will focus my comments on our fourth quarter and full year 2021 financial results and drivers, beginning with a high-level overview and commentary of our major product lines. I will also walk you through our 2022 financial guidance. Our detailed financial results have been provided in today's press release. During my remarks, I will be discussing both GAAP and non-GAAP measures and refer you to our press release for non-GAAP reconciliations. Total fourth quarter net sales were $302.1 million, an increase of 3.5% as reported, and 4.5% on a constant currency basis compared to the prior year period. Full year 2021 net sales were $1.139 billion, an increase of 8.4% as reported, and 8.1% on a constant currency basis compared to $1.051 billion in the prior year. Both fourth quarter and full year 2021 net sales reflected the continued impact of COVID-19 on elective procedures and hospital staffing shortages in particular. Despite these headwinds, we saw continued positive momentum for our new product introductions, including the Pulse platform and our cervical portfolio, led by the Simplify Cervical Disc. I will provide additional color on the performance of these innovative products a bit later. International net sales of $71.9 million in the fourth quarter of 2021 grew 3.9% as reported, and 7.9% on a constant currency basis compared to the prior year period. These results were driven by Asia-Pacific, primarily Japan and Latin America, posting double-digit growth. Europe declined slightly during the fourth quarter of 2021 compared to the prior year period due to COVID-related restrictions on elective surgeries. International net sales for the full year 2021 were $269.2 million, an increase of 15.3% as reported, and 13.7% on a constant currency basis compared to $233.6 million in the prior year. Notably, due to our continued growth outside the United States, our international business is now nearly a quarter of our total company net sales. During our third quarter earnings call, we discussed how NuVasive Specialized Orthopedics product availability negatively impacted our net sales for the quarter, particularly outside of the United States. During the fourth quarter, we began returning Precice titanium products to market, and I'm pleased to report that we are now back in the majority of our key geographies. Now I'd like to share some key highlights from our U.S. product lines. U.S. spinal hardware net sales were $160.5 million in the fourth quarter of 2021, representing a 3.4% increase compared to the prior year period. Full-year net sales were $610.8 million, an increase of 7.4% compared to the prior year. Within U.S. spinal hardware, our cervical franchise was a continued bright spot with net sales growth of 30% in the fourth quarter compared to the prior year period. For the full year, cervical net sales grew 23.7%, and we are very pleased to report we exceeded our original full year net sales expectations for the Simplify Cervical Disc. U.S. surgical support net sales were $69.7 million in the fourth quarter, which represented growth of 3.4% compared to the prior year period, primarily due to sales of the Pulse platform. Notably, the fourth quarter was the first full quarter since we commercialized the Pulse platform. Pulse performed well during Q4 and exceeded our full year expectations for net sales. Importantly, we are building a strong global net sales pipeline for future growth, as Chris mentioned previously. Turning now to operating highlights. Non-GAAP gross profit in the fourth quarter was $219.1 million, compared to $208.9 million in the prior year period. For the full year, non-GAAP gross profit was $832.8 million, an increase of approximately 14% compared to $730.7 million in the prior year. Non-GAAP gross margin for the fourth quarter of 2021 was 72.5%, an increase of 90 basis points compared to 71.6% in the prior year period. The year-over-year improvement was primarily driven by a decrease in inventory charges. Fourth quarter 2021 non-GAAP operating expenses were $180.3 million, an increase of 10.7% compared to $162.8 million in the prior year period. The year-over-year increase was primarily driven by investments in our commercial channel, higher labor costs, and increased freight and travel expenses. Non-GAAP R&D expenses in the fourth quarter of 2021 increased to $23.1 million as we continue to invest in the Pulse platform, Pulse Robotics and our core spine portfolio. This compared to $20.3 million in the prior year period. On a full year basis, non-GAAP operating expenses were $687.3 million compared to $614.1 million in the prior year. On a GAAP basis for the fourth quarter of 2021, we reported operating margin of -9.4% compared to +6.9% operating margin in the prior year period. During the fourth quarter of 2021, we recorded a charge of $46.6 million associated with an increase in the contingent consideration liabilities for the Simplify Medical acquisition, which in turn had a negative impact on our GAAP operating expenses and GAAP operating margin. Our acquisition of Simplify Medical included upfront consideration as well as future milestone payments. The remaining milestone payments are based on net sales from products incorporating the Simplify Medical technology and are payable in each of the years, 2023, 2024 and 2025. As Chris indicated, we are very pleased with the commercial performance and sales prospects for the Simplify Cervical Disc, and we updated our future sales forecast for this innovative technology accordingly. On a full year basis, GAAP operating margin declined by 480 basis points to -1.1% compared to +3.6% in the prior year. Fourth quarter 2021 non-GAAP operating margin was 12.9%, a decrease of 290 basis points from 15.8% in the prior year period. The year-over-year decline was primarily driven by costs from the addition of Simplify Medical, as well as continued investments in infrastructure, R&D and commercial, which were partially offset by supply chain efficiency gains. On a full year basis, non-GAAP operating margin increased by 170 basis points to 12.8% compared to 11.1% in the prior year. Non-GAAP other income and expense increased in the fourth quarter to $8.8 million of expense compared to $6.3 million of expense in the prior year period. The year-over-year increase was primarily attributable to higher unrealized foreign currency losses, primarily in Latin American currencies. For the full year 2021 non-GAAP other income and expense was $28.2 million of expense. Non-GAAP tax expense in the fourth quarter of 2021 was $9.3 million, compared to $9.4 million in the prior year period, resulting in an effective tax rate of 31% versus the prior year tax rate of 23.6%, primarily due to losses in jurisdictions without associated tax benefits. For the full year 2021, our effective tax rate was 25.1%. On a GAAP basis, we reported a fourth quarter net loss of $36.7 million, or diluted net loss per share of $0.71 compared to net income of $1.7 million or diluted earnings per share of $0.03 in the prior year period. This was largely driven by the increase in the contingent consideration liabilities for the Simplify Medical acquisition as discussed earlier. On a non-GAAP basis, we reported fourth quarter net income of $20.7 million or diluted earnings per share of $0.40 compared to net income of $30.4 million, or diluted earnings per share of $0.59 in the prior year period. For the full year 2021, we reported a GAAP net loss of $64.1 million, or diluted loss per share of $1.24 compared to a net loss of $37.2 million, or diluted net loss per share of $0.72 in the prior year. The 2021 GAAP net loss was largely driven by the Simplify contingent consideration liability increase, as well as inventory charges associated with NSO product withdrawals as discussed on our third quarter earnings call. On a non-GAAP basis, we reported full year 2021 net income of $87.8 million, or diluted earnings per share of $1.68 compared to net income of $63.8 million, or diluted earnings per share of $1.23 in the prior year. Turning to cash flow. Our free cash flow for the fourth quarter of 2021 was $11.9 million versus $44.8 million in the prior year period. The decrease was primarily driven by lower net income and working capital timing. For the full year 2021, we generated free cash flow of $71.1 million compared to $80.2 million in the prior year. Our balance sheet remained strong in 2021, with cash and cash equivalents of $246.1 million as of December 31, 2021. Our $550 million revolving credit facility remains undrawn. Turning to our full year 2022 financial guidance. I'm pleased to say we have great confidence in our business and expect the investments we have made over the past 3 years to come to fruition. At the same time, we recognize the volatile environment in which we're operating with COVID-19 and related healthcare staffing issues, as well as increasing inflationary pressure. Given those factors, we are guiding for worldwide net sales growth of between 5%-8% compared to the full year 2021 on a reported basis. We currently expect negative foreign currency impact of approximately 100 basis points for the full year. On a constant currency basis, we expect 6%-9% growth in 2022. Drilling down a bit further, from a phasing perspective, we expect the year to be more back-half weighted due to typical first quarter seasonality, which historically has been 5%-10% sequentially lower than fourth quarter levels. This is inclusive of Pulse and Simplify net sales ramping throughout 2022 after their product launches last year. We expect solid growth in our international business and to realize the benefit of NSO products returning to market, especially in the seasonally strong third quarter. We will continue to invest in R&D to drive innovation, competitive differentiation, and top-line growth in 2022 and beyond. Turning to non-GAAP operating margin, which we expect in the range of 13%-14.5%, reflects a return to a normalized level of spending, particularly in travel and surgeon training, as well as inflation-related impacts. Finally, we expect non-GAAP earnings per share in the range of $2.05-$2.35. We believe our guidance is appropriately conservative as it assumes that COVID and related healthcare staffing shortages will remain with us in 2022, but gradually improve throughout the year. The high end of our guidance range assumes modest impact to our supply chain from inflation and normalized operating costs. We remain focused on improving our operating margins to return to pre-COVID levels. Beyond that, we intend to grow our operating margins over time, and we'll provide updated targets at our 2022 Analyst Day. To conclude, despite macro conditions, we believe we have positioned the company for growth in 2022 with our full-line spine portfolio, including innovations such as the Pulse platform and C360. We are excited about the market opportunities in front of us, and we appreciate the continued dedication and contribution from the NuVasive team to help us achieve our mission to change a patient's life every minute. Operator, we're ready to begin the Q&A session. At this time, we will be conducting a question and answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary for you to pick up your handset before pressing the star keys. In the interest of time, please limit yourself to one question only. One moment while we poll for questions. Our first question comes from the line of Josh Jennings with Cowen. You may proceed with your question. Hi, good afternoon. Thanks for taking the questions, and I appreciate the detailed download and guidance for 2022. I had two questions on Pulse. Chris, I wanted to you know, you mentioned some of the software upgrades that were on tap, and I wanted to just better understand any other kind of upgrades to the system in front of the robotics module, including you know, procedural integration such as X360 and how that kind of roadmap shapes up this year. I have one follow-up. Yeah. Thanks, Josh. Excited about the progress we made on Pulse and obviously some of the early feedback. From the get-go, we were in a series of software upgrades that will go on somewhat in perpetuity as we move forward, as we look to add value to the system. Ahead of us are more instrumentation, more navigated instrumentation, potentially then integrating, as your point, more procedural roadmaps within the software upgrade. We'll likely do a software upgrade on an annual basis and add a lot of new functionality into the system. First one will happen later this year. We'll talk more about it at that time. Then from there, we'll continue to add in software and hardware-related applications as we move forward. Great. Just to follow up on Pulse, just thinking about the pipeline and the early success you've had on the very early days of the launch. Can you help us understand the mix of, are you placing these systems or is the pipeline filling up with, I guess, loyalist NuVasive surgeons or is Pulse attracting new surgeon customers? On top of that, you know, how should we think about kind of the hardware pull-through effect that Pulse could deliver in 2022? I mean, our assumption is that the low-hanging fruit is NuVasive loyalist surgeons and still gonna be in early launch days and the halo effect or pull-through effect will really occur in 2023 and beyond. Just curious how you guys are thinking about that in 2022 with the guidance that was set here today. Thanks so much for taking the questions. Yeah. Thanks, Josh. Early days, it's, you know, I said all along, we wanna be as flexible as possible to create an opportunity for our customers to access this technology. That being said, the majority of what we've seen so far have primarily been sales. It's a little early to really calculate pull-through. So to that end, we're trying to get a better sense. We're clearly measuring and monitoring every system placed and seeing what the halo effect will look like. We know it's there, but it's a little early to comment on. I don't know if, Matt, you have anything else on that. Yeah, Josh. We are gonna track it internally stating the obvious, but just so everyone's clear out there, you know, in the U.S. support, that's where Pulse is going. Any pull-through that we're gonna get though is gonna go through U.S. spinal hardware. You know, we're tracking both of those numbers, and at least for Q4 and last year, it's not enough for a conversation, but we hope that changes as we get throughout this year. Great. Any details on just the mix of surgeons that are either ordered or are in the pipeline, rather loyalist to V- Yeah. It's primarily been on the front side. It's been a lot of folks that have been involved with this in the past, so it has been some loyalists. I would say the pipeline, though, reflects a little bit different story. We're introducing the technology to new users. We're looking to bring in new users to experience the Pulse in our labs. So early adopters and early folks that were familiar with the project have been some of our first customers or first users for good reason, because we wanna really test the system as we've done over the last couple of months. But as we go forward, there's you know, it's more of a mix of both existing and new customers. It'll evolve as we move forward over the next couple of quarters, but that's what we see today. Great. Appreciate it. Thanks. Our next question comes from the line of Matt O'Brien with Piper Sandler. You may proceed with your question. Hi, good afternoon. This is Drew on for Matt, and thank you for taking the questions. You know, just looking at the guidance you're providing today, you're providing a pretty wide range on both the top line and the bottom line. I'm assuming you have a couple different scenarios baked in each part of the range there. I know you touched on a little bit as far as the bottom line goes, but you know, maybe you could walk us through you know, how you're thinking about each end of that range and maybe the base case assumptions around COVID and staffing shortages and all that kind of stuff that you've assumed in that range. Thanks, Drew. I'll take it, and I'll turn it over to Matt to go into a little more specifics. You know, we came out of the last quarter with a solid, we believe a very solid 2021 performance. We continue to make a lot of progress against our strategic plan with, as we talked a lot about, developing multiple vectors of growth. Now we're ready to execute on those things. We've continued to progress against our international runway, made significant progress there over the last couple of years. I think our guidance reflects those growth opportunities that we've developed. It also reflects the reality, which is we haven't had a non-COVID-impacted quarter since Q4 of 2019. Although I see the infection rates somewhat subside, I'm really looking at the durability in the volumes, and that's a function of staffing shortages, inflationary pressures, things that I can see the infection rate drop, but I don't know how these other situations that have been a sort of a byproduct of COVID play out over the next couple of quarters. I think our guidance sort of reflects the positives of what we've developed, but the reality of what we're still facing in the environment. It's a little uncertainty. Matt, do you have any? Yeah. I would just add that, you know, the guidance we gave of 6%-9% on a constant currency basis, which is really how we look at the numbers internally, you know, plus or minus, I'd say we're expecting about half of the growth in that 6%-9% to come from new product introductions. You know, that would include obviously Simplify and Pulse. You know, Chris talked about in the prepared remarks, Modulus ALIF, Cohere XLIF, Cohere TLIF. He also talked about a number of other new products that we're launching this year. Small net sales this year, but we hope to grow those in future years. About half from new product introductions, and then the other half is from continued international execution, some growth in U.S. core spine and then the NSO return, which really is a third quarter event. That's kinda how we're thinking about the guidance. The one thing I do wanna highlight though is that for Q1 specifically, we did say in the prepared remarks that we think we'll be down 5%-10% sequentially. We had a tough January like a lot of other issuing companies did, and so we were not immune to that, but we will see, you know, pickups in future quarters, particularly in the back half of the year. Full. Thank you. Our next question comes from the line of Matthew Blackman with Stifel. You may proceed with your question. Good afternoon, everybody. Thanks for taking my questions. Maybe one to start, Matt, on the operating margin guide. Is there any way to quantify how much of a drag the supply chain and inflation is baked into the guide? And any sort of directional color on how to think about where you expect to get the year-over-year leverage? Is it balanced across gross margin and SG&A, or is it more concentrated in one of those line items more so than others? I've got one follow-up. Sure. Matt, what we saw last year, we talked about this in previous calls, was we did see an uptick in freight cost, and we've accounted for that in the guidance that we've given here. But the key here is that we were able to absorb that through efficiencies in our supply chain. You really didn't see it if you were looking at our gross profit or gross margin as a percent of sales throughout last year. As you know, we came in for this quarter at 73%, which was notable. As I'm kind of running through the P&L, Matt, I would say we're still anticipating a bit of a gross margin improvement. Obviously we're keeping close watch on inflationary pressures, but we still think we'll be able to offset some of those costs. From an SG&A perspective, remember, we're still on a lot of product launches. We still have the lingering COVID uncertainty, and we see that manifest itself in our SG&A profile. We are certainly seeing inflationary pressure as it relates to, you know, compensation for our employees. All of those, we think we've accounted for in the guidance we've given. That's the reason why we gave a large range, 'cause we wanna make sure we give ourselves some room here since it's early on in the year. The final line item you're probably curious about is R&D. It's not gonna be growing to the same degree that it has in past years, but it'll still be higher. You can probably take the, you know, the $23 million we did in the first quarter here and multiply it by 4 and you're in the zone. Yeah, I appreciate that. My follow-up. Chris, we spend a lot of time talking about Simplify for obvious reasons. I was hoping to get a little bit more color on the performance of the broader C360 portfolio. Is there any way to talk to what growth in the portfolio is excluding Simplify? Or even if just generally how the portfolio is performing, you know, is it tracking to where you thought it'd be at this point? Just any color on the rest of the C360 portfolio would be helpful. Thanks. I don't exclude it, but I would just say that you know, the sum is greater than the parts. We're seeing now good doors open through Simplify to the broader C360 portfolio, and as we talked about, we'll be introducing Reline Cervical later this year. All in all, we think we've got a durable growth perspective that we talked about in some of the prepared remarks. We're looking forward to executing against that over the course of this year. Simplify specifically has been a highlight. It's been well received by our customers. We've now, as I've talked about earlier, completed some of the supply chain integration that we'd planned to do from the get-go, and we're ahead of schedule. At the end of the day, we feel very good about the cervical portfolio. We've got a lot of opportunity we've got to execute, but the broad portfolio, we think, plays very well, and we believe it's the most competitive cervical portfolio in the market. Yeah, Matt, the only other thing I would add to that is it's quite amazing how a year can change the landscape. On the fourth quarter earnings call last year, we were being asked by the analysts about, you know, why is cervical struggling. As we said in the prepared remarks, but worth repeating, you know, on a full year-over-year basis for the cervical portfolio, we're up 23.7%. For the fourth quarter alone, we were up 30%. Part of that is all of these coming in tandem together to deliver those results. Yes, Simplify is in there, but, you know, 30% for that portfolio is absolutely fantastic and, you know, I would not have predicted 30% in one quarter back a year ago. Our next question comes from the line of Matt Miksic with Credit Suisse. You may proceed with your question. Hey, good evening. Thanks so much for taking the question, and congrats on a really pretty impressive quarter on a bunch of different drivers. Just one question, if I could, on your comments, Chris, on ALIF, and then I had a follow-up on Pulse. On ALIF, I mean, it is notable your leadership there, you know, what's been happening, I guess, driven in part by X360. Could you talk about, you know, what else is driving that and, you know, what kind of runway you have to, you know, expand on that? I guess pun intended, but, you know, what sort of runway that part of your business has, and I mentioned one follow-up. Yeah. Thanks, Matt. You know, we're as we've been talking about, you know, the evolution of the company has been from sort of that early stage disruptor with XLIF to broadening our portfolio to be much more of a comprehensive spine player. You know, the most near adjacency to our XLIF procedure was ALIF. Obviously, we kind of housed that all in the anterior space, $900 million subsegment. So really, I think a lot of familiarity with certain surgeons that had used us on XLIF now moved over to the ALIF procedure. Obviously, Modulus ALIF played a very pronounced part. Our focus on training and education, dealing with access surgeons, I think played an impressive part in our growth. As I look forward, you know, we've got more launches coming on this year. Modulus XLIF, I think, will be a key invigorator to the XLIF procedure, as well as launching the prone lateral approach over the course of the year. We've got a lot coming in the anterior space. We are by no means, and I'll make sure everybody understands this, by no means are we moving away from our leadership position in anterior. We're complementing that with posterior and cervical and obviously introducing enabling tech to complement our broader portfolio. We're very bullish on our ability to continue to lead and take share in the anterior space. That's great. Just a follow-up on Pulse. You know, a couple things about the launch that, you know, we talked about a few times, and you got a lot of questions on ahead of the launch were things like, you know, what will be the preferred sort of economic, you know, pricing, contracting model for this, you know, purchase or contracting? The other being, you know, what's the what is the lead driver here? You know, there's lots of folks with navigation, not many, maybe not any other companies out there with navigation and technology to reduce X-ray exposure. I'd just love to get a sense of what you think the key pull is around this, in addition to obviously being, you know, integrated navigation system. Yeah. You know, I don't know that we have enough to say we have a preferred model. Clearly, if someone wants to buy it from us, we'll definitely take the outright purchase. I mean, we're clearly looking at this kind of came from the earlier question from Josh, around what's the pull-through scenario. That'll help us better understand the financial models that we think are most beneficial to our company. It's early days, again. You know, our goal is to get Pulse installed to be used in 100% of spine cases. We wanna make it easy for people to access this technology. We'll know more over the next couple of quarters of sort of the financial models that are probably most beneficial to us, and over a period of time. As far as the driver, you know, I've had a chance to talk to several surgeons over the last week, and it really comes down to workflow and the synergies and the accessibility of the technology. You know, navigation, LessRay, Bendini, all incorporated into a single user interface as we described, has resonated with our customers. We still have more work to do and more applications that we can add on, which I think is further exciting and actually starts to, you know, as we talk about extensible, extend the value proposition of what this technology represents. That's been the main driver. I mean, clearly, you have certain surgeons that love LessRay, certain surgeons that really love the Bendini aspect of it. There's differing voices coming from different components, but almost universally, the integration of technology seems to resonate with the customers, and we continue to hear that from our customers. Our next question comes from the line of Shagun Chadha with RBC Capital Markets. You may proceed with your question. Great. Thank you so much. Guys, just curious what the Pulse and Simplify sales were in Q4. What are you assuming in your guidance? I think you mentioned, you know, half of it is new product introductions, but it includes, you know, other items as well. Then I'm curious about the backlog. You know, by our math, NuVasive had, you know, one of the largest backlog or lost sales coming out of 2020 and 2021 relative to other companies that we track. What are you assuming in your guidance for that? Just, lastly, on inflation, I didn't hear you quantify the impact of inflation on margins. If you could do that would be helpful. Sure. I'll take a shot here, and then Chris, feel free to jump in. With regard to Pulse and Simplify, you know, early last year, we were clear to say that the goal that we put out externally was to achieve $5 million in net sales for each of those products. We exceeded that on both of those. For Pulse, really, if you look at, you know, U.S. surgical support, that's where you're gonna see Pulse for the fourth quarter in the coming years. That's where that growth is manifesting itself. With Simplify, rather than talk about Simplify, because what we know is that if you're only modeling Simplify and you're missing the whole point of C360 and ACP and things like that, you're not gonna really fully appreciate the growth rates that we're posting in cervical. That's how I would encourage you to think about it 'cause buried in that 30% was a lot more than just Simplify. You need to be thinking about that as you're modeling it. With regard to backlog, our forecast does not include a huge bolus of surgeries coming back. It is very hard to predict. Therefore, we have some modest recovery in there, but some of that's muted with hospital staffing shortages and COVID. We didn't put a specific number out there, Shagun, on inflation impact on margins, but what we did do is give ourselves a very wide range, as I said earlier, to make sure we can navigate inflationary pressure. But we certainly are seeing it on compensation costs. We saw it on freight last year, and we expect that trend to continue. You know, it's a dynamic environment. That's why we went with wide ranges. Yeah, I don't have anything to add. Obviously, on the backlog, you know, we've seen, you know, quarter to quarter, Q3 as an example, last year, we saw volumes we thought were down roughly 10%. It's hard to tell, and the mix is a little different as some of the non-acute care, the ASC type of procedures may have gotten done. Some of the more complex cases or trauma obviously may have gotten done. Some of the degenerative cases that were more elective in nature may have been what the impact was on us. We started to see those come back, but it's been, to Matt's point, more gradual. With some of the constraints now with some of the staffing shortages and hospital clinical staff, I don't see the opportunity, at least not yet, for an acceleration or a catch-up, if you will. I think it'll happen gradually over the next several quarters. You know, if that changes, we'll obviously see it and feel it and talk about it. At this point, that's sort of the prediction. Yeah. Shagun, just to be crystal clear, my comment around Pulse units we placed last year were in the U.S., so that, the math is clear there. We do have one European commercial contract that we've received in Q1. More to come on that, but just to be clear. Our next question comes from the line of Jason Wittes with Loop Capital. You may proceed with your question. Hi, thanks for the question. I just wanna know if there's any on surgical solutions, maybe a discussion of what's going on outside of Pulse. I mean, you sort of answered it. It seems like most of the growth within that business, if you're saying Pulse exceeded $5 million, was from Pulse. Just curious to know just kind of what the broader implications is for the remainder of the surgical solutions business. Yeah. I mean, Surgical Solutions has been roughly flat for us over the last several. We have the NCS business housed there, as well as our biologics business. NCS was clearly a reflection of the volume, and it's very much volume related on the NCS. Biologics has been a little choppy for us. We feel like we're in a stable position. Generally speaking, we sort of consider the U.S. surgical support as with the market, and right now the market's still flattish in our, at least from what we see today. The implication is that, and that's kind of what Matt said, is that you know, the Pulse success or the units that we're selling will reflect into the U.S. Surgical Support business. That's kinda how we'll set a barometer on it. Okay. Thank you. Just a quick follow-up. Is there an update on the robotic arm timing? Yeah. There is actually. Well, maybe not a big update, but some update. You know, I've gone through this before in the robotic world, and there's a lot goes into the robotic program, and not just the arm, but software, instrumentation, in-cart electronics, the end effector work you do. The good news is we've made progress in each of these areas over the last several quarters, over the last couple of years. While there's no change to our previously communicated timeline, I will say we've continued to invest in R&D resources. We've completed significant number of labs internally over the last several quarters, and made progress against, you know, our design development process. We do have a key milestone in Q2 that we believe will give us very you know, very good insights to our clinical readiness. Stay tuned. We are starting to really track in now the anticipated first in man. We've got a critical milestone that will be coming up in Q2, and we'll inform you in that timeframe kinda where we are. Our next question comes from the line of Craig Bijou with Bank of America. You may proceed with your question. Thanks, guys, for taking the questions. Let me start with Simplify, and I wanted to see if you guys could provide maybe a little bit more color on how you see it being used. You know, is it one level, two level? And then just the surgeons that are using it, are they, you know, maybe NuVasive loyalists or surgeons that are using other products of yours or are they more competitive surgeons that were disc guys and, you know, were previously using other types of discs? Thanks, Craig. You know, we are excited about the Simplify technology, obviously it brought us to cervical as Matt talked about. Is it 1 level or 2 level? It's both. It's been early days. Demand has clearly outstripped our supply, but we're catching up, and we've talked about we'll be in a better supply position over the course of this year. It's a mix of surgeons, both current and competitive surgeons, but I would say that it's attracting new surgeons to our company. You know, many surgeons will do both thoracolumbar and do cervical. Some surgeons are more specialized, and those surgeons that are more specialized, maybe haven't seen our cervical portfolio. It's definitely a door opener for us. It's differentiated technology. We've got the unique 4-millimeter option. We're the only 4 millimeter on the market. We've had folks comment on actual individual employees of ours that have had this procedure done that had the 4 millimeter option in their surgical procedure. We're seeing both current and competitive surgeons, but I would say I'm excited about how this attracts new surgeons to NuVasive. It's a cervical space, as we talked about. We've been underrepresented there, less than 5% share. We're excited about going after introducing new surgeons to NuVasive, and potentially, as I said in my prepared remarks, driving more density and more customer adoption at the hospital level. Got it. That's helpful. Thanks, Chris. And maybe a second question on the NSO business. You've talked a lot about it today. You haven't necessarily talked a lot about it historically. So just wanted to, you know, maybe see if you guys could provide a little bit of color on the size of that business, you know, maybe the impact or the growth impact that it could have in 2022, and then even the prospects for that going forward, given that you are coming out of the, you know, pulling it off the market and then getting it back on. Yeah. You know, we haven't talked a lot about it. It hasn't been overly material to us, looking back, but I can tell you, I'm excited about the highly differentiated technology. It's taking the MAGEC extension rods and applying them to new applications, and we've done a lot of work on the portfolio. Clearly, we've done a lot of work over the last year to get it back to market, but we are continuing to really look at ways to accelerate this business. We haven't talked a lot about it because it hasn't been overly material, and it's been something that we've sort of grown in the background, complementary to the MAGEC technology. Something you'll probably hear us talk more about. I'll turn it to Matt to talk about the immediate NSO impact this year. Yeah. We mentioned in the prepared remarks that we're happy to be back on the market. We still have a few more markets we're working through, but you know, the reality is the reason we wanted to bring it up as you guys are putting your models together is that Q3 there was a significant impact last year. We believe we'll get that $10 million-$15 million in net sales back this year with about two-thirds of that being international and a third being domestic. As you're thinking about it, that's how we're thinking about NSO. Our next question comes from the line of Allen Gong with JP Morgan. You may proceed with your question. Hi. This is actually Rohan on for Allen. I just wanted to get a better sense of the COVID situation in the quarter and into Q1. At the JP Morgan conference, you kind of distinguished between the Omicron wave and prior ones, and that many patients were kind of forced to quarantine if members of their household tested positive, and this was causing an abnormal amount of delays in procedures for the quarter. Given this dynamic and I guess a pretty robust recovery over the last several weeks since the commentary, can you give your outlook on procedures for Q1 and better quantify maybe how many of those deferred procedures were ultimately scheduled and how this recovery is also contemplated in guidance? Thanks. Yeah. It's still a little tough to tell. I would just say that, you know, coming out of Q3 into Q4, we saw a better Q4 than a Q3, and clearly Q3 is where you had the Delta variant really hit heavily in September. We also started hearing staffing shortages hit around that time. Improvement through Q4 with the Omicron coming in in the, you know, late November, early December, and accelerating into January, where we saw, you know, another real depression in our volumes in January. Good news is February has improved, and we continue to see improvement. Now we don't know what the staffing shortage will have on if there's a ceiling, if you will, of what the hospitals and the clinical settings can take on, and that's reflected in our guidance. It's a bit of uncertainty. We are, as I said before, bullish on what we've developed and the investments we've made and how that plays out over the year. We're still a little uncertain on the underlying base business and how quickly we get back to pre-COVID volumes. That'll play out, we hope, through March and into April, where we get more durability. You know, my hope is to get a durable quarter where we can truly say we didn't have a COVID impact. I don't know when that is. It's not this quarter, and it may not be next quarter, but we hope it is before the end of the year. Our next question comes from the line of Samuel Brodovsky with Truist. You may proceed with your question. Hi, thanks for taking the question. We're running up on time, so I'll just do one on Simplify. Thanks for the color you gave earlier on the call around the manufacturing shift to Ohio. Just kinda trying to get a better idea, if we can get a little more granular into how that transition is going and how long we should think about Simplify being supply constrained through this year. You talked about the assembly and packaging getting approved late in the year. Is that, should we think about it more not being supply constrained into 2023, or can it still sequentially grow through 2022? Thank you. Thanks for the question, Sam. Let me make sure I clarify. We took sort of two pathways. We optimized the existing supply chain that we took upon the acquisition of Simplify Medical. That yields a significant higher level of supply through the first few quarters of this year. We've also taken the path that I mentioned in my prepared remarks around moving manufacturing to Ohio. It also requires us to do the assembly and packaging PMA approvals to fully complete the process. The good news is, we have increasing supply through Q1, Q2, Q3, within a phase II of supply increase by moving into West Carrollton. The complete story here is we don't believe we'll be in a supply constrained environment. We think demand will ramp over the course of the year as our supply ramps, and we feel like we'll be in a good supply state all through the course of 2022. Ladies and gentlemen, we have reached the end of today's question and answer session. I would like to turn this call back over to Mr. Chris Barry for closing remarks. Thank you. Thank you all for joining us for our earnings call today. We'll continue to focus on executing our strategic plan to deliver growth and shareholder value in 2022 and beyond, and we can all work together to help transform surgery, advance care, and change lives. I look forward to speaking with you all after the first quarter. Thank you. This concludes today's conference. You may disconnect your lines at this time. Thank you for your participation. Enjoy the rest of your day.
