I'll now turn the call over to John.

Thank you, Susan, and welcome everyone to today's call. As you can see in today's results, the fourth quarter was a strong finish to an impressive year for Tandem. In looking back at the highlights of the year, we set record sales for both the quarter and the year. We also furthered our leadership position in markets outside the United States with expanded international launch of our ControlIQ technology. Operationally, we focused on continuous improvement throughout our business, and we reached an impressive milestone of achieving our first year of positive operating margin. Finally, as we highlighted at our R&D day late last year, we furthered our product development efforts to support our near and longer-term portfolio. In addition to these accomplishments, just last week, we achieved the exciting milestone of FDA clearance of a mobile app that enables our T-SlimX2 pump users to bolus insulin from their smartphone. With this clearance, we are adding to the list of tandem firsts, as this is the first-ever FDA-cleared smartphone app capable of initiating insulin delivery on both iOS and Android operating systems. Organizationally, we've also been enhancing our structure over the past few quarters with the creation of new senior leadership positions. We've welcomed talented and experienced individuals who complement and strengthen our management team as we scale the business and prepare for continued growth, near-term product launches, and the execution of our longer-term strategy. It's an important step as Tandem has a great opportunity to further our market-leading position in diabetes care. Our installed base has nearly quadrupled in the past three years, which is evidence that our innovations drive adoption. I am proud that nearly 330,000 people worldwide use the T-Slim X2 for their therapeutic management. Credit for these achievements goes to our talented employees who have demonstrated great flexibility and an outstanding commitment to improving the lives of people living with diabetes. As we look ahead, 2022 is positioned to be another exciting year for Tandem. We're also being mindful of and prepared to continue navigating the challenges associated with the pandemic. It's encouraging to see headlines showing a decline in COVID-19 cases, but as we've seen historically, things can oscillate quickly. In addition, the broader effects of the pandemic, such as staffing challenges in the clinics we serve and the global supply chain headwinds, will take time to recover and will trail case rate improvements. That being said, While pandemic-related uncertainties still remain, our focus and commitments to achieving our goal is unwavering. Importantly, our growth drivers from recent years are still in place today. These include an underlying worldwide market that remains large and underpenetrated, a robust competitive conversion opportunity, strong demand for our automated insulin dosing technology, our innovative product pipeline, the positively different experience we provide our customers, and the growing renewal opportunity from our current customers who are eligible to purchase a new tandem pump again. Brian Hanson, our EVP and Chief Commercial Officer, has seen each of these firsthand, and I'd now like to turn the call over to him for him to share his perspective on the quarter and the year ahead.

Thanks, John. What stands out for me is that our T-Slim X2 platform continues to be the leading insulin therapy solution for the durable pump community, which is the largest segment of the insulin pump market. In fact, recent US data suggests that more people chose the T-Slim X2 last year compared to any other pump offering and that the market is continuing to accelerate. We estimate that more than 70,000 people in the United States adopted insulin pump therapy for multiple daily injections in 2021. which is double the number of people who adopted pump therapy just three years ago. Outside the United States, we see a similar trend that suggests that pump therapy penetration is also accelerating. With this market growth, I am proud that Tandem continues to make meaningful progress in our longstanding goal to bring the benefits of pump therapy to more people with diabetes. In the fourth quarter, we once again saw a balanced source of new customer growth in the United States with approximately half of our customers reporting that they've converted from another pump manufacturer and have from multiple daily injections. We're also gaining increased visibility into our growth sources outside the United States, where we see both a high number of competitive conversions and people new to pump therapy. It's a testament to the ease of use and form factor of our platform, its software updatability from a home computer, the proven performance of our control IQ technology, and the customer experience we provide. In January, we held a virtual national sales meeting, which was great timing as the Salesforce expansion from 95 territories to 110 territories is now complete. At the meeting, we heard high enthusiasm for our T-SLIM X2 pump and strong conviction in our Control IQ technology. The team was coming off a seasonally demanding fourth quarter where they put in the extra time and effort to ensure that our customers who wanted to get a new pump before year end were able to do so before the typical reset of deductibles. This year was particularly interesting as many offices shifted back into remote interactions in the fourth quarter during the resurgence of COVID-19 cases. Healthcare provider offices were often pressured with staffing shortages and there was a wide range in how they were operating. I was very proud that our team remained flexible, shifting and adjusting to support the prescribers in whatever way worked best for their practices. Outside the United States, our international distribution partners also continue to navigate the challenges of COVID-19, which varies greatly by country and by region. Despite these challenges, we achieved record sales in only our third full year of commercial activities outside the United States. Our success was driven by multiple factors, such as the scaling launch of our Control IQ technology, which is now offered nearly everywhere we operate outside the United States. In addition, our T-Slim X2 was available for a full year in both Germany and France, which represent two of our larger markets and where Control IQ was launched in the fourth quarter. As a reminder, outside of North America, we work with experienced distributors who are responsible for all the selling, reimbursement, and customer care activities. It's been fantastic to hear their feedback on product adoption and similar to what we hear in the United States, the customer experience with Control IQ is overwhelmingly positive. This helps to fuel demand for our products as more people experience the benefits of Control IQ and healthcare providers see the clinical outcome improvements this innovation provides. It's been a tough environment for distributor forecasting and inventory management. And in addition to the high growth dynamics of our product launch and the pandemic, they are also navigating the associated supply chain complexities. For example, the timing and availability of sea freight has been a variable that they've had to contend with that has been difficult to predict. As a result, we've seen and anticipate will continue to see the variability in distributor ordering patterns throughout 2022. Turning to the competitive environment, It was largely consistent worldwide throughout 2021, as well as in the more recent weeks. In the United States, our sales team was thrilled to receive last week's news of FDA clearance for our T-Slim X2 pump users to bolus using the T-Connect mobile app. It's significant, as this clearance provides people the freedom and discretion of having their most frequently used pump feature available on their personal smartphone. The updated mobile app also continues to offer the benefits our customers have already been enjoying, including a convenient way to view their pump alerts on their phone, which serves as a discrete secondary display for their pump, and automatic wireless uploads of pump therapy data to our cloud-based T-Connect web application. We are kicking off training on the new mobile bolus feature for our internal teams now, followed by healthcare provider trainings, and then we'll be progressing the launch as a tiered rollout throughout the spring with availability for everybody this summer. This launch is a prime example of the power of our Tandem device updater and how it provides the T-Slim X2 with a competitive advantage. In the upcoming months, we'll be able to offer nearly 240,000 of our in-warranty U.S. customers access to the mobile delivery feature free of charge. And it's easy to get through just a software update to their pump, and their app that they can perform in the comfort and convenience of their own home. That's the type of innovation that truly makes our offerings positively different. It is also an opportunity for us to connect with existing customers who may be waiting on the sidelines for a reason to buy their next T-Slim X2. As a reminder, customers typically become eligible for a new pump purchase once every four years. Our experience, though, is that many customers will not pursue that renewal pump purchase until well after their warranty has expired. averaging roughly a year later. We continue to enhance our internal infrastructure and processes to drive customer renewals and are seeing great results. For example, in 2021, we hit a milestone where more than 70% of customers whose warranties expired in 2016 have now purchased their second or even third pump, which speaks to the high retention for our customers over a lengthy timeframe. Our speed is improving. The percentage of customers purchasing a pump within six months of their warranty expiration has improved for the third year in a row, and nearly half of our customers newly eligible in 2021 have already renewed. That is fantastic progress, as many people who are eligible did not become so until the fourth quarter. As you can see, 2021 was a busy and accomplished year, and our commercial initiatives are well positioned to continue being a driving contributor to our longer-term growth objectives. With that, I will turn the call back over to John.

Thank you, Brian. At our R&D day event in December, we shared our longer-term vision and strategy for driving continued growth through innovation. It's rooted in a foundation of extensive market research, which is a practice that we began at the company's inception. A consistent outcome from these results has been that there is no one-size-fits-all solution in diabetes management. How a person chooses to wear their pump is a big driver in their purchasing decision, and it's based on personal needs and preferences. As a result, this creates segments in both the Type 1 and Type 2 markets, and our portfolio approach is designed to bring new solutions to more people living with diabetes. We are continuing to invest in advancing our T-Slim platform, along with bringing our miniaturized durable pump to market, as well as tubeless options. From a timing perspective, the next new pump we intend to launch is a tandem Mobi, which we historically refer to under its development name T-Sport. Mobi gives us an opportunity to serve a new market segment with an even smaller, more discreet pump using leading-edge hardware technology. We chose the name Mobi to represent the pump's mobility in the way it's worn and as a nod to its mobile app-based interface. The Mobi Pump is designed to be fully controlled through a mobile app on a user's personal smartphone. The T-Connect mobile app that was cleared last week for bolus insulin delivery is also the foundation of Mobi's mobile control functionality. Last year, during the regulatory review for our mobile bolus feature for the T-Sylinx2 platform, we were able to get clarity on the FDA's expectation for pump mobile control functionality. and all that learning has been applied to the Mobi full control mobile app development effort. Mobi has been extensively tested, including more than 15 rounds of formative human factors testing. This gave us high confidence as we entered our human factors validation study, which is now underway. This is the largest human factors study in the company's history and will be used to support the 510 filing to the FDA later this summer. As a reminder, MOBI will be submitted to the FDA through the ACE Pump 510 pathway, which allows for it to be integrated with interoperable algorithms and CGMs without additional regulatory review. This is particularly relevant for the commercialization of MOBI, as we will be evaluating timelines to determine which ICGM will be integrated when we first launch. CGM integration work has been progressing well with both our CGM partners, Dexcom and Abbott. These are strategic priorities for us in 2022 so that our customers can benefit from new sensor technologies along with the features of our AID algorithms and insulin delivery systems. We are also making great progress on our clinical initiatives for advancing Control-X Hughes labeling and feature set with a few milestones of note. We currently are enrolling our first Type 2 feasibility study Our pediatric trial is progressing well, and as discussed in the past, we intend to use the data to pursue an age indication for children younger than six years old. And we also have several other studies in progress and in the planning phases to further support our AID programs. As we look to the year ahead, it's once again primed with opportunities to bring the benefits of our technologies to more people living with diabetes. I am confident in our team's ability to continue meeting and exceeding our near and longer-term goals, as well as delivering relentless innovation and revolutionary customer experiences to the diabetes community. With that, I'll now turn the call over to Leigh.

Thank you, John, and good afternoon, everyone. 2021 was another record-breaking sales performance for us, as we scaled from just under 500 million sales in 2020 to more than 700 million in 2021. This represents 41% growth over 2020, which we successfully delivered despite the unique and unpredictable challenges of the pandemic. We shipped nearly 130,000 pumps worldwide, of which approximately 30% were shipped in the fourth quarter alone. This brings us to a worldwide installed base of nearly 330,000 customers. Fourth quarter worldwide sales were a record 210 million, which as a point of comparison is meaningfully more than our full year sales in 2018. This is a significant achievement in only a three-year timeframe. Specific to the U.S. market, 2021 sales grew 26% to 525 million. More than half of our sales were driven by shipment of approximately 83,000 pumps in the year. Our U.S. installed base of nearly 240,000 customers also drove meaningful growth in our supply sales and builds the foundation for pump renewal sales in the future. Following on Brian's remarks regarding our renewal progress, we reached our goal to renew approximately 60% of the more than 65,000 pump warranties that cumulatively expired to the end of 2021. While the majority of the renewals this year were generated from 2021 warranty expirations, there was still a meaningful contribution from warranty expirations as far back as 2016, and we expect continued renewal sales in the future from warranties that expired in years past. As we look at our 2022 renewal opportunity, approximately 30,000 additional customers will become eligible for renewal based on our 2018 shipments. Importantly, more than 40% of these customers will not be eligible for renewal until their warranties expire in the fourth quarter of 2022, which will influence the timing of those renewal sales across the year. Fourth quarter sales in the U.S. were $161 million on 26,000 pump shipments. benefiting from the traditional seasonal uptick we experienced due to the timing of insurance deductible resets and the highest volume of renewals we have shipped in a single quarter. Outside the U.S., our presence continues to strengthen across the more than 20 countries in which we operate. We ended 2021 with $178 million in sales, which was 114% growth over 2020. Just over half of the sales were derived from 45,000 pump shipments, essentially doubling our installed base outside the U.S. to nearly 90,000 customers. We ended the year with strong fourth quarter sales outside the U.S. of 49 million on 12,000 pump shipments, reflective of the continued strong demand for our products, but impacted by the variability in ordering patterns that we saw throughout the year due to the challenging COVID environment, as Brian discussed. We anticipate that these fluctuations will continue into 2022, For example, certain distributors exited 2021 with sufficient inventory to meet first quarter demand and are anticipated to place lighter follow-on orders in the first quarter of 2022. Therefore, we anticipate Q1 orders for both pumps and supplies will be lower than the fourth quarter of 2021 as distributors continue to focus on achieving optimal inventory levels. Looking to 2022 worldwide, we have significant growth opportunity from our market-leading ControlIQ technology. especially in the markets outside the U.S. where it is still in the early phases of commercialization. Our recurring supply sales also represent a meaningful and predictable revenue stream that will increase proportionately in 2022 with the growth in our sizable installed base. We are maintaining a cautious approach in 2022 for impacts that COVID may have on the business, particularly as we reflect on the continuous surprises in 2021, even at times when markets began to reopen. For these reasons, we expect our 2022 worldwide sales to be in the range of $845 million to $860 million, a growth rate between 20% and 22%. Due to U.S. seasonality and international ordering patterns, we anticipate Q1 will be the smallest sales quarter of the year at approximately 19% to 20% of sales, similar to years past. Our U.S. sales guidance includes annual expectations in the U.S. of $630 million to $640 million, or growth of 20% to 22%, with pump sales scaling up across the year in line with historical seasonal patterns. Overall in the U.S., sales in the first quarter tend to fall in the high teens as a percentage of our full-year sales due to the impact of insurance-deductible resets impacting both pump shipments and supply sales. Sales expectations outside the U.S. are estimated to be in the range of 215 million to 220 million, or growth of 21% to 24%. While market demand remains strong in the markets where we operate, we expect that COVID impacts on the timing of distributor orders are likely to continue to create a high degree of variability in sales across the quarters. Therefore, we are being conservative with our OUS guidance as we monitor the dynamics with each of our distributor partners. Sales are expected to be lowest in Q1 with growth across the year as we continue to penetrate the various markets and increase our installed base, keeping in mind that some seasonal pressure tends to occur in the third quarter due to the European summer holiday season. Moving on to margins, we continue to demonstrate improvement in our gross margin in 2021, increasing to 54% from 52% in 2020. This reflects an approximate 10% improvement in the per unit production costs for both our pumps and cartridges. While overhead reductions are a contributing factor as our volumes increase, we are also seeing notable benefit from cost saving initiatives. These benefits more than offset the impact of lower average selling prices from increased pump sales in the OUS markets, as well as growth in our supply sales from our large installed base. As a reminder, US pumps are our highest gross margin product, followed by OUS pumps and then overall consumables. Pump sales were 59% of worldwide sales in 2021 compared to 63% in 2020. Our fourth quarter gross margin of 54% was essentially flat compared to the same period in 2020. We continued to drive product cost savings through the end of the year, but these benefits were partially offset with increased costs associated with global supply chain challenges that we began to incur within the period. Additionally, both international sales and supply sales represented a higher percent of our overall sales in the fourth quarter of 2021 as compared to 2020. Looking ahead to 2022, we expect to achieve an annual gross margin of 54%. This is in line with 2021 due to increased material and freight cost expectations, which we anticipate will continue to be a burden in 2022. We are continuing to drive our cost-saving programs to offset these cost increases to the extent possible. We view this as a more temporary impact to the business and remain confident in achieving our long-term goals while managing these near-term cost pressures. We expect to achieve gross margins of 65% by 2027 with incremental progress across the years from scale and cost-saving initiatives, but more significantly in the future from new product introductions and reimbursement initiatives. Our 2021 operating margin of 3% marked another milestone achievement for Tandem, which was the first time that we reported a positive operating margin on a full year basis. By comparison, our operating margin was negative 2% in 2020. This is meaningful as we continue to demonstrate progress on the path to achieving our long-term profitability objective. We continue to view our adjusted EBITDA margin, which excludes non-cash stock-based compensation, as the appropriate metric to measure our near-term profitability progress. That margin improved two percentage points to 14% in 2021, reflecting expansion in line with our gross margin improvement year over year. We took a more significant step up in our R&D investments in the second half of 2021 to drive our pipeline programs, including hiring of key personnel and commencing a number of clinical trials. Our top financial priority is to invest in product and business model innovations to deliver sustained high revenue growth. These investments will continue into 2022 as we also build the foundation for leverage in the long term. We anticipate our full-year adjusted EBITDA margin will be in the range of 14% to 15% and that we are well on track to achieving our long-term operating margin goal of 25%. Our cash and investments substantially increased by $139 million in 2021, ending the year at a balance of $624 million. We believe we are well positioned to make the necessary investments to execute on our strategic plans. To summarize our 2022 outlook, worldwide sales are estimated to be in the range of $845 million to $860 million, including sales outside the U.S. of $215 million to $220 million. We estimate gross margin for the year to average 54% and adjusted EBITDA to be in the range of 14% to 15% of sales. Our non-cash charges for stock compensation, depreciation, and amortization are expected to be approximately $90 million, included as components of both cost of sales and operating expense. In conclusion, I am proud of our financial achievements and overall execution in 2021 that were made possible by the efforts of our amazing employees. TANDEM is positioned to break records once again in 2022 as we continue to carry out our mission by bringing the benefits of our solutions to more people living with diabetes. With that, I will turn it over to the operator for questions.

As a reminder, to ask a question, you will need to press star 1 on your touch-tone telephone. To withdraw your question, press the pound key. Please stand by while we compile the Q&A roster. Our first question comes from the line of Chris Pasquale of Guggenheim. Your line is open.

Thanks, and congrats on a nice finish to a strong year. I wanted to just drill in on the renewal opportunity, something that should be a big driver for you guys over the next couple of years. It would be great to just get an absolute number for what you think the renewals were in 2021. You gave a lot of details around rates, but it would be great to have a baseline there.

I'm sure. Thanks for the compliment, Chris. I'm happy to talk to you today. So with regards to renewals, first of all, I'll say that, yes, it's becoming a growing opportunity, which will be much more meaningful in the coming years. For 2021 and even again for 2022, the vast majority of our pump sales will still come from pumpers new to Tandem. We have made great progress, though, and it's not that we aren't renewing people. It's just that the opportunity volume hasn't grown as much. So in 2022, it's going to increase by about 30,000 new opportunities, which is where we'll really start to see more contribution, but it's pretty back half loaded. So you can think about it as more of a 2022 and into 2023 opportunity. And just to give you maybe a little more perspective on that breakdown, you can think of the new pumpers as still being, you know, more than 80% of what we shipped in 2021. Okay.

That's helpful. Thanks. And then on margin, you know, flat gross margin 22 versus 21, you know, maybe not too surprising given some of the cost pressures the industry is dealing with broadly, but it was good to hear you reiterate the long-term goal. Just curious on the drivers there, how much of it is dependent on new products? How much of it is dependent on reimbursement, which is a little bit out of your control as you think about getting to 65 long-term?

Sure. So when you think about it, I usually put it in three buckets. What you've been seeing us demonstrate is really the incremental benefits each year as we grow our volumes, leverage our overhead, and just keep identifying cost-saving initiatives and efficiencies within the processes themselves. The real step changes will come when we launch new products. So, for example, with Mobi coming, once we get to a level of scale, we've estimated that that product cost should be about 20% better than the T-Slim itself. So you can see that's where you'll start to see step changes going towards that 65% long-term goal. The reimbursement initiatives are more similar to incremental progress like we're seeing on the volume side. It's really about continued conversations with the insurance payers, getting more direct contracts, and looking for price increases as we move along, especially as we're using our clinical data to share the benefits that their patients are seeing. So you can think about it within those three ways.

Thanks. Thank you. Our next question comes from Brooks O'Neill of Lake Street Capital. Your line is open.

Thank you, and good afternoon. Congratulations on the terrific finish to 2021. I'm just curious, Lee, if you could talk a little bit about the assumptions you include in the 2022 guidance. John mentioned, I think, two CGM partners, both XCOM and Abbott, and I'm curious how you think about the impact of G7 and Libre III. and then whether you've included an assumption about contribution from MOBI in the 2022 guidance. Thanks a lot. Okay, thank you, Brooks.

So in terms of guidance, just our overall philosophy is we typically do not include products not yet approved in any of our guidance levels. So to answer your questions on CGM as well as MOBI, those would not be factored into our 2022 guidance at this point. What has been included, though, is the continued enthusiasm for Control IQ. it still has not yet reached its full market potential. Even here in the U.S. where it's been around now for two years, but especially outside the U.S. where we're just starting to roll it out in France and Germany, you know, in just the recent months. And so we still think we have a great runway with Control IQ. And now with the addition of mobile bullets, it gives us a lot to talk about with our customers.

Great. Thank you very much.

Thank you. Our next question comes from Larry Beagleson of Wells Fargo. Your line is open.

Hi, this is Nathan on for Larry. Just a question sticking to 2022 guidance. What are you assuming for a competition? We just saw Omnipot 5 approval, but we also have Medtronic's warning letter and potential impact to their pump. So what's assumed in your guidance?

Sure. Thanks for the question. So when we think about what's included, I already mentioned control IQ, but in particular, we still think we're going to continue penetrating the MDI population and see growth in competitive conversions year over year. As we think about competition this year, we really factored in, I would say, more at the noise level. If you think about it, we're still the leading player in the durable pump segment, which is the largest of the segment. And we don't see a lot of switching back and forth between tubed and tubeless pumps. And so at this point, So we're considering at noise level, like we have seen in the past where new products are launched, and sometimes it causes a little bit of near-term disruption.

Okay, that's helpful. And then you previously indicated that you plan on beginning the type 2 control IQ pivotal study in 2022. Can you provide an update on timing? What do you think you would need to show in the study to achieve traction in type 2? And also, when would you expect the type 2 label, and how important is this to you?

Thanks, Nathan. Well, right now, we're enrolling our Type 2 feasibility study. And this is something that we've worked with the FDA on to just understand the various segments of the Type 2 community and just to test them out in a smaller study. It turns out that, you know, sometime, you know, I would say that probably late next year or early 2023, we would initiate our Type 2 pivotal study. It's going to be a large study, and I think that's roughly what we would expect for timing. So I think we're looking at an indication probably in the 2023 timeframe.

Great. Thank you.

Thank you. Our next question comes from Alex Nowak of Craig Harlem Capital. Your line is open.

Great. Good afternoon, everyone. With several diabetes approvals making their way through the FDA in the last couple weeks, are you starting to see the backlog at that agency start to ease a bit here? And then when you take the learnings from mobile bolus, you document those, and then you fold that into MOBI. How are you thinking about what you need to change to MOBI, additional studies that might be needed on the bench side? And then how are you thinking about timing for approval there?

Yeah, good questions, Alex. You know, I would say it's difficult to say still as to whether or not the FDA has, you know, got additional resources that have come back from, you know, just supporting the COVID work that they're involved in. So I think we have to wait and see still. I would say that they've been very supportive. They've been, you know, with the limited staff, and we're very happy and appreciative of to get the approval, but it's still early in my mind, and I think we need another quarter or two to see if, in fact, things do change there. You know, when it comes to Moby, I would say that, you know, we learned a great deal. There was not a lot of new information that came as they did approve the device, which was good. And so I would say that right now we're – you know, we've essentially – We've incorporated the learnings from the questions that we received last year into MOBI at this point in time. And we've really transitioned from a development mode into more of a testing mode. As I indicated, we're involved right now in the largest – summative study that we've done for human factors testing. We did at least 15, maybe 15 or 17 formative studies leading up to it, so there's a great deal of experience and we're comfortable with the results, but it's a very complex study. It's going to take several months. It's going to be involved. Multiple cities will be involved. Multiple types of segments within the diabetes community will be involved. So it's a long and extensive study, and so that's really You know, we have to finish that. There's also additional verification, validation studies, and testings that we have to do inside the company. So, you know, I think that puts us to, you know, a summertime submission. And, you know, we feel good about that.

Okay. I hope that's helpful. And then with outside the U.S. just becoming much more important to the company here, can you just give us an update on where you stand today as far as your pump versus the installed base of pumps out there, the share of new pumps being placed outside the U.S. market? And then just how has Medtronic 780G launched their change to sales process for you?

So I'll start with a little bit on just color of where we stand today. If I understand your question correctly, you know, please correct me if I'm wrong here. When you think about where our business is coming from, it's much like the U.S., where there's a high level of competitor conversions coming our way, as well as people new to MDI. So we continue to penetrate those markets, and we're especially excited about Control IQ and the the great demand that we're seeing and interest in that product as we look forward. And then if Brian wants to talk a little bit about the selling environment as it relates to 780G out there today.

Yeah, I think as we see here in the U.S., we see the power of control IQ in our international markets as well, and we really haven't seen a dramatic increase. influence or shift from that product in the markets that we compete against today. So we feel pretty good about it. We certainly have a lot of visibility with our partners. We have great relationships with our partners. We have balanced growth across all the regions we're in right now. So the early indications are Control IQ is doing very, very well. That's great.

Appreciate the update. Thank you. Thank you, Alex.

Thank you. Our next question comes from Steve Lichtman of Oppenheimer & Company. Your line is open.

Thank you. Hi, everyone. You saw a solid 4Q, so obviously able to overcome COVID headwinds. I was wondering what kind of impact you did see from COVID in the quarter and what you're seeing as the year turned. And as you mentioned, John, COVID cases have started to come down.

I'll take that one. This is Brian. It was an interesting year for sure. And I think, you know, the best thing we can probably say is we remain cautious because we've kind of been here before. As I said in my earlier statement, I'm very proud of the team and the work they've done over the last two years. And in Q3, we saw things kind of open up, but it was characterized by almost an extended holiday or vacation period. And then as we moved into Q4, we had a lot of optimism. The new variant came, and it began to change access for us to our patients and our healthcare providers. We first saw it in Europe, and then we saw it here in North America. So we kind of migrated back towards our remote model in many regions. And thankfully, we were pretty good at that. The difference in Q4 was we saw a lot of COVID-19 positives at that point. We saw it with our healthcare providers. We saw it with some of our patients. And we saw it internally here with our staff, internal and external, and our partners. So it was just an odd quarter to, you know, kind of navigate through. We did so successfully. We certainly hope that it moderates now when we head into some clear waters in 2022. But, again, we are, you know, cautious.

Yeah, I think there's still uncertainty as we move into this year. And we'll just have to keep our eye on it.

All right. And then also in the commercial organization, what kind of tailwind could the expanded sales force have provide in 22? You have a nice growth in the commercial team. Is it getting you into new regions you weren't in before or more about going deeper? And will we see a material benefit from the expansion in 22 or is that more meaningful in 23?

Well, I'll start with the purpose behind it. One was to reduce some of the workload on our existing staff because they were simply getting a lot of patients to handle in their current territory. So going from 95 to 110 was to ease a little bit of that burden. But then that allows us to do exactly what you said, go a little deeper in our existing accounts. and also get out and see some additional accounts that we may not have spent as much time with. So we opportunistically looked for those areas where we were just getting a little bit too large and we may not be doing all that we could be doing in that area. So this allowed us to right-size the sales side and the clinical side a little bit. And, yeah, I do think it's certainly going to provide some benefit for us this year, and our folks were very happy to get that relief. Lee, do you want to talk any further to that?

That's great. Cool.

Thanks, Larry.

Thanks, everyone.

Yep. Thank you. Our next question comes from Matthew O'Brien of Piper Sandler. Please go ahead. Matthew, thanks for taking the question.

So just to put a little bit finer point on the potential tailwind on the Medtronic side of things, I think they said, you know, $200 million to $300 million is the impact they expect this year, just using the midpoint of that. $250 million, I think around half of that is insulin pumps and supplies. And, you know, I'm assuming the majority of those folks are into durable pumps. So as I look, Lee, at the domestic guidance, it looks like you're only factoring in, I don't know, somewhere in the $10 million to $20 million range from that tailwind. Are those numbers kind of ballpark? And then, you know, I guess why be so conservative with the potential tailwind on the Medtronic side?

Sure. Thanks for the question, Matt. So we haven't actually quantified, obviously, how much we're thinking about it, but I guess one point to make is we were coming into this year, I think many people thought that our competitive conversion opportunity was going to go down, where in fact we still expect that it will increase this year and maintain that same healthy balance of new pumpers coming from MDI and competitive conversion. So we still think the opportunity is strong, but As is our nature and as we're continuing to navigate the COVID environment, we're going to be cautious initially until we see continued trends that might suggest otherwise.

Okay, so there is some conservatism built in based on what you've seen from Medtronic so far. That's correct. Okay, thank you. And then on the competitive side, you know, is the control IQ momentum that you have, is a form factor enough? to really dislodge a bunch of existing patients or even new to pumping patients heading, you know, heading into, you know, the full launch of a low five? Or do you need to see, you know, real-world data for a year kind of post-full approval? Or, you know, is the momentum so strong with CIQ that it's really going to be difficult to slow things down from a momentum perspective in terms of what you've got going? Thanks.

I'd say briefly we're really comfortable with our position and certainly where we sit right now. The competitive messaging that's out there is it's early to tell. We certainly haven't seen a reduction in our pipeline and these phased rollouts. We'll surely learn more over the coming periods here. But, boy, Control IQ and the outcomes that we've seen for Control IQ continue to be a real positive for us. Launching Mobile Bullets is an exciting opportunity for us to get in to visit our accounts. The product pipeline certainly leads to great things at the end of the year and the next year. And then the services we provide and our infrastructure we have in place I think puts us in a really good spot.

And, Matt, I'd just add to that that the – When you look at the algorithms themselves and you look at the results, there's not a whole lot of significant differentiation. I would say that it's some convergence of anything. And there's more to it. We really do believe form factor is important. And when you look at our pipeline, we've got Control-IQ on TSLIM doing very well today. We've got MOBI filing here shortly. We've got additional sensor partnership integrations, which I think are really going to give us a sales boost as well with this new technology. And then we've got, you know, we've got X3, we've got Mobi Tubeless, and we've got Patch here in the next three to five years. So I think that, you know, we feel very well positioned to compete. And as Brian said, there's not a lot of information out there right now. We're going to have to wait and see what happens. But we feel in a very strong position to compete. with the other players in this market. Got it. Thanks so much. Take care.

Thank you. Our next question comes from Matt Taylor of UBS. Your line is open.

Excuse me. Hi. Thank you for taking the question. I did want to ask one follow-up on you mentioned that you're baking in some conservatism to the international guidance. Maybe just Talk about what you're seeing, how conservative you're being, and what's the FX number that we should be using for international?

Sure. Hey, Matt. So I'm actually going to let Brian talk about the environment a little bit because I think that helps explain better the caution that we're putting into the guidance. But I'll take the simplest one first, which is we have very little FX exposure, so nothing to speak to in terms of from a materiality perspective.

You know, we have great relationships with our partners. We have great visibility to the work that they're doing. And, again, we talked about the balance of just growth across all of our regions. It was an interesting end to the year. As we prepared to launch Control IQ in Q3 and into Q4, especially in our newest geographies, we encountered several factors that made it quite complex. One was the unknown demand. These were large markets that we were going into, specifically France and Germany. They're newer partners for us. There's different distribution models in those countries, which makes it even more complex, and one of the reasons they were a little bit later in our launch cadence. And there were some really unique supply chain issues that hit us in Q4, whether it was by air or by sea. It was hard to get things out the door and on schedule over there. So there's plenty to learn from Q4. The good news is the demand for control IQ continues, and the variability that we're experiencing should take care of itself as we move into the middle part of the year. And as we talked about, the competitive environment remains fairly strong in our position right now, so I remain pretty bullish on what we're doing.

Okay, great. Thank you for the comment. Appreciate it.

Thank you. Our next question comes from Danielle Antalfi of SVB LRINC. Please go ahead.

Hey, good afternoon, everyone. Thanks so much for taking the question. Can you hear me okay?

We can. Thanks, Danielle.

All right. Yeah, so thanks, guys. So congrats on a strong end to the year. And just a question on where we are with penetration today. Leah, I think you've mentioned that something like double the number of new patients started on pump therapy this year versus three years ago. How are you feeling about your long-term sort of target out there for pump penetration and type 1s based on where we exited the year? And then one follow-up on international.

Danielle, I'll go ahead and take that. I mean, I think we feel very positive about continued pump penetration. And it's not just being driven by tandem, but when you look at the diabetes med tech community in general, there's been a tremendous amount of innovation that's occurred over the last couple of years. And there's more innovation coming. And I think that it's all intended to just reduce the burden of diabetes. And we believe that ease of use drives adoption. We've stated specifically that we think we can get to 60% to 65% penetration. And when you look at our pipeline, we think we've got innovation that's going to continue to drive that, as well as our partners and competitors. So we think it's a number that's going to continue to expand. And as you said, we've seen aggressive growth in MDI penetration in the last couple of years. We expect to see it continue to happen, and not only in the U.S. markets, but also OUS, as we bring this technology to Europe and other countries that we're in today. We think it's going to happen there as well.

Well, you front-ran my question, John. My next question was going to be on some of these major international markets. where what the incremental, maybe that's a better way to think about it, incremental runway for penetration is versus where we are today. And what's going to drive, what are going to be the markets that drive you over the next few years internationally?

I mean, I think the factors are the same. The same factors that are affecting pump penetration improvements in the U.S. are going to occur OUS. And I would say right now, you know, our numbers would suggest that the pump penetration in the markets we're in today is approximately 5 to 10 percent. And we think that can probably double, maybe more than double in the next three to five years. And that's also, it's a much larger market, as you know. In the States, it's approximately 5 1.7 or 1.8 million people with diabetes. In the markets we're in today, it's 4 million. And so as we make improvements in the pump penetration there, it's a much bigger number for all of us to participate in.

Yeah, got it. Thank you, guys.

Take care.

Thank you. Our next question comes from Jason Bedford of Raymond James. Your line is open.

Good afternoon. I have a few questions here. Maybe for Brian, you mentioned over 70,000 folks adopted pump therapy in 21. Just embedded in the guidance, what's the expectation for that number in 22?

Thanks. We haven't given a specific number other than we think that our ability to penetrate the MDI population will continue to increase in 2022. So the drivers that have made us successful so far are still there. It's more MDI patients coming our way. It's more competitor conversions. And it's an increase in the number of renewals that will ship this year.

Okay. Okay. I guess just on the renewals, you mentioned an incremental 30,000 coming due, I think, in 22. Can you just update us on the actual number of renewals, either exiting 21 or 22? We can back into one of the years. But what's the actual number of renewals out there?

Sure. What we actually achieved by the end of 2021, there's more than 65,000 people whose warranties have expired over the years since the beginning. And we have renewed a significant portion of those. And so what we're looking at as we go forward, I think one of the things to think about is the information we gave today on where we exited 2021. which is that nearly half of the people whose warranties expired in 2021 have already renewed. So you can think about that as you look forward into 2022 and what that additional 30,000 opportunities might provide for us. And 2021 is not done, and 2020 is not done. There are still people coming from way back that will continue to be renewal opportunities as we look forward.

Okay, so... I had a number about 60,000 exiting 22. Is that in the ballpark? Oh, sorry.

I don't think I gave you that specific metric. Of the more than 65,000 customers, 60,000 have renewed by the end of 2021. I mean, sorry, 60% of them. Sorry. I was going to say, wow.

I know.

Okay. Okay. That's helpful. And then just in terms of mobile bullets in Europe, can you just talk about where you are, your thoughts there, and then maybe some of the challenges of introducing such technology in Europe where I think they have stricter laws around privacy?

Yeah, great question. You know, when you looked at the results today, you can see about a quarter of our revenue came from OUS. And I think that, you know, we've quickly become an international company. And I think that, you know, we need to structure our product pipeline so that it also represents and provides this technology and innovation to the OUS countries. So we're absolutely committed to providing Mobibolus and Mobi and all of our products OUS. It's something that we have to do. You know, I think you're right. There's some complexity. But right now, as we've talked about in the past, you know, we are rolling out Tandem Source. Right now it's in the U.K. in a, I guess, early release state, and the intent of Tandem Source would be to integrate with mobile technology. And so it's definitely something that we have on the roadmap. We just haven't been very clear yet intentionally about what the timing is, but I think that will come in time.

And so mobile bullets in Europe is more of a 23 dynamic than 22. Is that fair? I mean, that's a fair thing to say, yes.

We haven't been that clear about it, but I'd say it's fair. Okay. Thanks. You're welcome. Good talking to you.

Thank you. Our next question comes from Jeff Johnson of Baird. Your line is open.

Thank you. Good afternoon, guys. John, maybe one clarifying question for you and then one pump volume question, modeling question for Lee. But on the clarifying side, you know, you talk about ACE pump submission for Moby maybe middle of the midsummer or summer of this year, I think you said. Is there anything with an ACE pump submission that would make us think that it's more than kind of a typical or less than a typical six-month 510K review pathway? I mean, I know COVID has created uncertainty around review timelines and But historically, we think a 510 case is about a six month. So is that fair with a MOBI submission? So maybe a late 22, early 23 kind of potential approval timeline is a way to think about it?

You know, I think that's very fair prior to COVID occurring. But right now I think that it's still, I think the jury's still out as to how much additional resources the diabetes group at the FDA get in the next couple of months. We hope that things return to normal by that time because we'd, of course, like to get the product on the market as quickly as possible. But I think there's this inherent uncertainty in their resource and staffing levels at this point in time. And we're going to have to wait a little bit more time just to see how it plays out.

Okay, so ex-FDA assumptions, an ACE pump, kind of that typical six-month is a fair way to put it. Yeah, it is, yeah. Yeah, perfect. And then, Lee, just from a pump volume standpoint, I know you don't guide to pump volumes, but I'm going to ask a question around that anyway. You know, when I look at your U.S. pump volumes in the first half of this year of 21, they grew over 30%. In the second half, I think they were up upper single digits. You know, is your guidance for 22 kind of implying somewhere in between there, comps ease, hopefully COVID falls off a little bit, so maybe pump volumes in the U.S. grow somewhere between the second half and the first half of 21? Is that a reasonable guesstimate for the year?

Yeah, you know, I think it's challenging to take the growth rates in 2021 and apply any, you know, sense of normalcy to it. If you think about really what was happening in the base year of 2020 and COVID had the most significant impact in the first half of that year. And in the back half, what we were starting to see was we were actually starting to feel optimistic at that point. And it seems like things are getting back to normal. And maybe a little bit of that pent-up demand from the first half of the year was coming through. So that's why the growth rates in 2021 probably are maybe a little bit unfair. But thinking of somewhere in the middle I think makes sense for this year. You know, we look at it as more the terms of the seasonality curve and where you come off of that launching point with pump shipments in the U.S. usually being in the high teens as a percent of the year and in the fourth quarter, just kind of depending on, you know, it might vary in years where we had product launches, but anywhere in that 30-plus percent range.

Yeah, that's helpful.

All right, thank you.

Take care, Jeff. Thank you. Our next question comes from Josh Jennings of Cohen and Company. Your line is open.

Hi, this is Brian in for Josh. Thank you for taking my questions. I have two longer-term ones on the tubeless opportunity that's in the pipeline. First, Competitor today revealed its intention to commercialize a patch pump since this comes after the R&D day. Does it in any way change your views on Tandem's eventual opportunity in the patch market segment?

Not at all. In fact, I think we were aware of the investment that they had made in the company in the past. And, you know, it's not surprising that they're considering doing this. Yeah, so it's not a surprise. It doesn't change our own decisions and, you know, our strategy of moving forward with products that support both tubed and tubeless segments.

Okay, thank you. And my follow-up is just generally speaking, can the U.S. regulatory success you're accruing for tube pumps be leveraged to streamline the FDA process for the development of a patch pump, or are those two very distinct realms for the agency, tube pumps and patch pumps? Yeah, I was going to say, I'm thinking about factors like the size of a pivotal trial, or are we just too far out to do that? know the exact scope of work there?

Well, I would say that, you know, when it comes to actually working with the FDA on these filings, we have a great deal of experience with it. We've been doing it now for many years, and we understand the types of data and the depth of the analysis that we need to provide. So I think our team is very experienced when it comes to these sorts of filings. I'll also say that, you know, the entire initiative of interoperability benefits us. And I don't think that they have distinguished whether or not it's a tubed or a tubeless pump when interoperability comes to play because one of our competitors does have the ACE pump designation for a patch pump. So, you know, I think that the regulatory landscape is not going to, you know, impact us one way or the other. We just have to continue to produce well thought out analysis and justifications for the technology. And if we do that, I think we will continue to be successful.

Understood. Thanks again.

Thank you. And ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
