Good morning, everyone, and thank you for joining us today on our Fourth Quarter and Full Year 2017 Financial Results Conference Call. I'll begin with an overview of our fourth quarter and full year financial and operational highlights, followed by Fred, who will provide a detailed financial review. I will then return for closing remarks before opening the call for questions. First, I'd like to thank our team at OrthoPediatrics for their dedication in making 2017 a transformational year. We increased sales growth and profitability, completed a public offering, and changed the lives of approximately 20,000 children. Concerning fourth quarter results, we're pleased to report another consecutive quarter of strong revenue growth, which contributed to another year of 20% plus sales growth. Total revenue for the fourth quarter increased 24 percent, to $11.7 million, compared to Q4 2016, and increased 22%, to $45.6 million for the full year, compared to full year 2016. All three of our product lines contributed to both the fourth quarter and the full year performance: trauma and deformity; spine, which we are now going to refer to as scoliosis; and ACL reconstructive/other, which we are now referring to as sports medicine and other. However, we were particularly pleased with the growth of our U.S. scoliosis segment, which considerably outpaced our overall growth in both the fourth quarter and the full year and significantly outstripped the growth of the industry. Furthermore, we're also proud of the improvement in profitability that we achieved in the fourth quarter and full year 2017. Gross margin for the fourth quarter was 76%, up from 68% for the same period last year and 76% for the full year 2017, compared to 71% for 2016. This increase was in part driven by transitioning stocking distributors in select geographies to a sales agency…

Thanks, Mark. Total revenue for the fourth quarter 2017 was $11.7 million, up 24% when compared to $9.4 million for the same period in 2016. U.S. revenue in the fourth quarter 2017 increased 21%, to $8.8 million, when compared to $7.3 million in the same period last year, representing 75% of our total revenue. International revenue in the fourth quarter 2017 was $2.9 million, a 33% increase compared to $2.1 million in the same period last year, representing 25% of our total revenue. Total revenue in 2017 was $45.6 million, a 22% increase compared to $37.3 million for 2016. U.S. revenue in 2017 was $34.9 million, a 21% increase compared to $28.8 million for 2016, representing 77% of our total revenue. International revenue in 2017 was $10.7 million, a 27% increase compared to $8.5 million for 2016, representing 23% of our total revenue. Our fourth quarter and full year 2017 revenue breakdown by product category was as follows. Trauma and deformity revenue in the fourth quarter 2017 was $8.5 million, a 27% increase compared to $6.7 million in the same period last year and $32.8 million in 2017, a 22% increase compared to $26.8 million in 2016. This was driven by double-digit growth across the majority of our product line. Scoliosis revenue in the fourth quarter 2017 was $2.9 million, a 22% increase compared to $2.4 million in the same period last year and $11.6 million in 2017, a 24% increase compared to $9.3 million in 2016. This was driven by strong product acceptance and customer adoption, supplemented with growing sales competency in the U.S., partially offset by a slight reduction in international scoliosis sales due to the timing of cash collections. Lastly, sports medicine and other revenue in the fourth quarter of 2017 was $286,000, representing an 18% decrease…

Thanks, Fred. Let me summarize in five points. One, our strong fourth quarter and full year results keep OrthoPediatrics on a steady growth trajectory of at least 22%. Two, we continue to expand and enhance an already extensive portfolio of innovative surgical technologies, while also driving market penetration. We are deepening our understanding across the range of unique pediatric pathologies our surgeons treat and the very different surgical procedures they employ and our commitment to clinical education. Three, let us not underestimate the power of culture driving our success. We have a company -- we are building a company that is both performance-oriented and focused on engaging on our people. Four, our dedicated sales organization has developed strong relationships with our surgeon base and is able to cross-sell all our products during every surgery they attend. Five, we are committed to increasing the number of children we can help this year with our technologies by tripling the number of consigned sets using proceeds from our IPO. It is for these five reasons that we enter 2018 well positioned for substantial growth, and the outlook for our business has never been brighter. Operator, we'd now like to open the call for questions.

[Operator Instructions] Our first question comes from Kaila Krum, with William Blair.

So, I guess to start on that $10 million in instrument sets you guys are expecting to deploy this year, first, can you talk a little bit -- I guess can you tell us, I guess, how much of an investment perhaps you've made perhaps year to date, and then how you're thinking about contribution per set in your 2018 guidance?

Good morning. Yes, so as we've talked in the past, right after the IPO completed in October we came back and in the fourth quarter ordered approximately $5 million of those sets. That $5 million has been trickling in late into the fourth quarter and throughout the first quarter, and we plan on completing that $5 million of sets here at the end of March and starting to deploy that both in the U.S. as well as into the international markets. So that's the first big wave of the sets that are going to be consigned. We also have placed a significant order in the first quarter, which we expect to be delivered here in the second quarter, and then we'll be deployed at the end of the second quarter. And then in the third and fourth quarter of this year there'll be fewer amounts, smaller amounts, to total about that $10 million we talked about. As we talk about the contribution that those will make, first of all, it takes anywhere from 6 to 9, maybe 12 months for those systems to be fully utilized. Historically, we have driven a return of about $1.64 of annualized revenue for every dollar that we deploy. But we also know that we were overutilizing the sets that we have today, and I'm using in my model about $1.00 of incremental revenue for every dollar that is deployed. On the trauma and deformity side we think that's similar to the industry average. It's a little conservative, but right now that's what we're using in our model. As those sets gradually become more and more utilized they'll reach that dollar, maybe a little higher than that in the future, but for right now that's what we're using to model the contribution from those sets.

Great. That's helpful. And then I guess, I mean, you guys have talked about a lot of new and exciting product launches. So I guess how are you thinking about new product contribution, again, as it relates to that 22% growth guidance? Thank you.

Yes, so historically when I look at the growth of the business and look at the drivers it's very textbook. It's really a third from new customers, a third from additional sales with our current customers, and a third from our new product introductions. It's very -- it was a little surprising when I saw how evenly it was distributed. So that's kind of how we see the overall growth model going forward is coming from those three drivers. And, as we've talked in the past, all three of those drivers require incremental consigned sets. And so we think that the incremental consigned sets that we're going to be deploying will help all three of those areas to continue to grow the overall growth rate of the business.

Got it.

Our next question comes from Matthew O'Brien, with Piper Jaffray.

Just to start off with on the distributor side of things, we'd love to hear a bit more about how the conversions went in terms of getting your agency reps up and going there. Did you see any big churn in terms of customers or anything else like that? And then, along those lines, as you're going to do more of these have you disclosed how many more countries you're going to convert, and is that the potential, or is there a potential for some headwind from those conversions on the revenue side?

Matt, thanks for the question. The bottom line is that we were delighted by how these conversions went in the U.K. and Ireland and Australia and New Zealand. They, frankly, exceeded our expectations. And I think one of the reasons that the conversion worked so well is that there was no change in the selling organization. They were the same reps who were calling on the same surgeons. What changed was the fact that we were able to make decisions about the pace and the location of the deployment of instrument sets. And I think that's the key requirement as we would look at other stocking distributors and the conversion of those, that there not be any disruption to the relationships that sales reps, that their sales reps today have, with customers. We have not disclosed the number or the location of the stocking distributors in future. There is another one that we're working on now. But we want to take this at a judicious pace to see to it that the same success we enjoyed last year with these conversions is achieved this year.

That's helpful. And then along the lines of what Kaila was asking on the instrument side, and I may have missed this, but you've got a bunch more sets that are out there already. You're going to have even more. Can you just talk a little bit about exactly where some of those sets are going between existing and new accounts, and then the opportunity that you now have, given some of these additional resources, to open new accounts and drive even more business as we exit this year and into '19?

Absolutely. So, just to be clear, we really haven't deployed any yet. So we're getting ready to deploy the incremental sets here at the end of March, so those will start being deployed and will be completed by the end of March, and so we'll start to see some incremental revenue from that April going forward. We're really spreading it across all areas. So it's pretty evenly spread across our T&D business and our scoliosis business. It's also evenly spread across our historical product lines that we've been selling for many, many years, as well as recent product launches that we launched last year. And then as we go into future rollouts, particularly in the second and third quarter of 2018, there will be significant dollars there for the new products that we'll be launching this year.

Helpful.

Our next question comes from Rick Wise, with Stifel.

Let me start off with the sales. Mark, you commented, I think, that you'll continue to scale the sales force from the 75 currently. How do we think about maybe the ultimate right size, and how many folks are you thinking about adding this year, and maybe any incremental color about where you're going to deploy these people? Is it new regions? Is it adding to existing teams? Just any more details on that side would be helpful.

Yes, Rick, that's a very good question. The way I think about this is that in 2017 the sales force grew proportionally with our sales, and we expect that to occur again this year. I think the key point to remember is that the decision of adding more sales reps is not ours alone. We have a significant input in that decision, but the decision is ultimately made by our 33 domestic sales agencies. And so for that reason I think the structure of the selling organization is particularly scaleable in terms of where demand is growing in particular regions of the country. And for that reason we're very confident that this model is a lot better at keeping pace with our robust growth than if we were to say, well, we can only afford to hire X sales reps this year and we were to budget for it ourselves. That said, however, we are focusing a great deal of energy in California, which in particular is an enormous market, and our sales agency there has been very receptive to adding new personnel. Likewise, our business in the mid-Atlantic states is growing extremely robustly, and we have been adding sales representatives there through our sales agency.

That's great. Mark, for you, as well, maybe talk just a little about we're down -- a number of us are down in New Orleans at AAOS. I know this is not the most sort of important meeting of the year for you, but anything -- I know you all were down here, anything new competitively that we should be sensitive to, or just in general competitively?

Well, you know, Rick, we see nothing, really, in terms of competitive activity that is at all a change from the environment we have been operating in. We continue to see focused competition in the scoliosis area, as you might imagine, from companies like Medtronic and DePuy Synthes, but we see very little in the trauma and deformity area. So I would have to say that there is nothing we are seeing that would represent a significant change in the competitive environment in which we play.

Okay. And just last for Fred, two quick ones. Fred, cash ended a little over $42 million. Just help us think about the 2018 cash burn rate and where you would hope to end up the year. And last, obviously you're not giving quarterly guidance or anything, but just should we think about the flow of the quarters this year in the context of the growth rate you gave us as roughly similar to 2017? Is that the right way to think about it?

Thanks, Rick. Yes, so on the cash side, as shown in the adjusted EBITDA, in 2016 it was negative $1 million. In 2017 it's effectively breakeven. And so we're really proud of the fact that we've kind of turned that corner, and obviously with incremental revenue growth you would expect that that number would become positive in 2018. And so really the cash usage really comes down to deploying sets. And so obviously roughly this $10 million we'll be using to deploy sets in 2018 is the single biggest user of the cash driver in 2018.

Got you. And the quarterly flow?

Yes, I think it's probably similar to 2017. The growth, you would think, would accelerate maybe a little bit as these additional sets are deployed here starting in the second quarter and throughout the year. So I would guess that that's pretty similar to 2017.

Our next question comes from Ryan Zimmerman, with BTIG.

So a lot of questions I'm going to ask, but I just want to ask you certainly had gross margins stronger, I think, than we expected this quarter, and you communicated on what drove that, but just your thoughts around gross margins headed into '18 with new product introductions. Should we expect any incremental pressure on gross margins just to start in FY '18? Thank you.

Thanks, Ryan. The simple answer is no. We do not anticipate negative forces that will cause gross margins to decline due to competitive or market reasons. Likewise, the gross margins of all of our products are remarkably similar in percentage terms, and so we would anticipate that the margins of the new systems that we will launch will be comparable to those that we now have. That said, we are always trying to scratch out incremental price increases and to see some gross margin uplift in the product lines, but that certainly is not going to be anything discontinuous.

Understood. And then just to follow up, you certainly talked about the seasonality of the business, Fred, and just on the sports medicine business, I recognize it's a small portion of the business today, but it is variable quarter to quarter. Does that, in your view, start to smooth out, per se, over time as that grows? Will we continue to see some variability in that segment? Thank you.

Absolutely. Yes, I mean, obviously it's a smaller portion of the business and it'll probably smooth out as we go forward. Typically it's a little stronger in the fourth quarter actually, but, as you saw in this fourth quarter compared to last year, one of the drivers is the set sales in the international stocking distributor markets. The business is just so small if we sell a few sets that drives quite a bit of sales there. But overall it would smooth out as we go forward.

Understood.

At this time I'm showing no further questions. I'd like to turn the call back over to Mark for closing remarks.

I've already said my piece. Perfect. So I'd like to thank everyone for joining us on this call, and obviously Fred and myself are always available if there are any particular questions the shareholders might have. So thank you for your support and your participation this morning.

Ladies and gentlemen, thank you for your participation. You may now disconnect. Everyone have a great day.
