Patrick W. Smith - Co-Founder, CEO & Director
Thanks, Andrea, and welcome, everybody.
2018 was a record-breaking year.
We drove top line growth of 22%, and the bottom line grew more than twice as fast, with adjusted EBITDA up 53%.
We raised $234 million in a follow-on offering, turned our balance sheet into a fortress, we acquired VIEVU, and as a result, accelerated the largest police department in the United States onto the Axon network.
We released a completely redesigned Fleet in-car video system that's vying for market dominance.
We released several groundbreaking software features, including Axon Citizen, and we booked $389 million in business in the software and sensor segment, which is up 34% year-over-year.
We also finished the year with a stellar Q4 for every product line.
We had a record quarter for TASER, record quarter for software and sensors, record quarter for international revenue and a record quarter for total company bookings, including a record quarter for Fleet.
And of course, in the last month of the year, we began shipping the all-new TASER device, TASER 7, which connects to our software network.
We're excited about the momentum and initial customer response on the features and offerings in the Officer Safety Plan 7, or OSP 7, which bundles our next-generation body camera, Axon Body 3, with TASER 7 and with free Axon Records for 5 years.
We announced that at the IACP conference, which is the International Association of Chiefs of Police, last October to time it for the 2019 procurement cycle, and we expect healthy attach rates in the back half, especially once AB3 starts shipping.
We're seeing great customer response to the TASER 7 Premium Certification Plan.
Our major city agency customers in particular view it as a significant upgrade over the X2.
Demonstrating this for the first time interest the history of TASER, customers are demonstrating a willingness to upgrade earlier than 5 years, which is a statement to the utility and quality of the product and its value proposition.
In order to facilitate customers who wish to upgrade with weapons less than 5 years old, we offered a prorated trading program.
Credits for trade-ins of weapons less than 5 years old accounted for some of the margin compression in the quarter.
But in my opinion, it's a very strong indicator that customers really do want to take advantage of the new features in TASER 7, and they don't want to wait for their old weapon to hit end of life.
I personally want to thank the 76% of voting shareholders who approved our exponential stock performance plan earlier this month.
It has brought new energy to the workforce, and of course we are excited that it drives total alignment between shareholders, the executive team and every US employee.
We still have some work to do to roll it out internationally.
We have lawyers and accountants that are working on that now.
Our first operational milestone is either $710 million in revenue or $125 million in adjusted EBITDA, and I can tell you we are laser-focused on hitting those first goals and beyond.
It's encouraging to a CEO to have our employees thinking and making decisions just like long-term shareholders.
That's all for me.
Luke?
Luke S. Larson - President
Thanks, Rick.
The year is off to a strong start with several key wins.
We look forward to welcoming the Swedish Police Authority onto the Axon Network.
That's the first European nationalized police force to deploy Axon body cameras and go on the Axon Network.
We also received notice a few weeks ago that the Phoenix City Council approved a $5.7 million contract with Axon Enterprise to provide 2,000 body cameras for the department and evidence.com.
We have a few more wins up our sleeve for both TASER 7 and body cameras that we look forward to announcing in the coming days and weeks.
Some of you who have been with us for a while know that in late 2017, really led by our new CFO, Jawad, we pivoted our company culture to focus more on driving profitability.
It was important for us to demonstrate leverage on the body camera business after years of heavy investment.
So 1 year ago I stood up in front of the company and I declared that I'd shave my head if we hit our 2018 EBITDA goals.
So it's with mixed feelings that I share with the team -- or share with everyone -- that the team rallied, and we did indeed hit those goals.
In fact, we exceeded them, even accounting for about a $10 million-related loss with association of acquiring VIEVU in May.
And so several employees took turns shaving my head onstage during our annual company kickoff, which we privately broadcast to Axon offices all over the world.
It was a pretty great moment for almost everyone except my wife.
I also got a heck of a sunburn at the Phoenix Open, and I'm sharing this with all of our shareholders to let you know just how committed I was to driving this metric and the tone echoed throughout the organization, as evidenced by weekly reviews of our expense structure.
And of course, I recognize that even as we demonstrate successful annual leverage, Axon remains in a period of under-earning while we invest in major growth opportunities.
We feel great about our 2018 performance, for the cost controls we began implementing in late 2017 cleared the way for us to acquire VIEVU and make the right decisions for our customers and for the long term while still meeting our full-year profitability targets.
Turning to 2019, I'm laser-focused on 3 primary execution items.
The first is ensuring that TASER 7 is the most successful TASER rollout ever, and it's being very well received in the market.
The second is launching our next-generation body camera, Axon Body 3, midyear, which is our first LTE-connected camera.
This is great timing.
The launch of Axon Body 3 coincides with the rollout of the first dedicated first responder cellular networks by AT&T, FirstNet, and Verizon, both of which are Axon partners.
And third, we're extremely focused on delivering the Axon Records software product to our launch partners.
Double-clicking on this third one, let's talk about what a successful Axon Records rollout looks like.
We need to nail the product and we have the right team in place to do that.
We also need to really succeed in our early deployments.
In 2019, the key goal is to gain a foothold and delight our early launch customers.
We also want to sell Axon Records through our Officer Safety Plan 7 bundle with the TASER 7 and Axon Body 3 so customers are set up for the full Axon experience.
We're feeling really great about 2019, and now I'll turn over the call to our CFO, Jawad.
Jawad A. Ahsan - CFO
Thanks, Luke.
I've never felt better about how the company is positioned for growth.
We've proven we can execute.
In 2018, we did what we said we were going to do despite a pretty substantial headwind from VIEVU and one of their large domestic customers.
We have terrific momentum on our top line, driven by investments in our products and teams, with international picking up and the Fleet business vying for market leadership.
I also feel great about having more than $800 million in total company backlog and the fact that annual recurring revenue for software has crossed $100 million in 2018.
Axon Records and Dispatch are right around the corner, and we feel good about Records coming online and contributing to bookings in 2019.
On the bottom line, this is the first year in our company's recent history that we hit our profitability goals, and we expect that to continue going forward.
I'm very proud of the team for embracing a new level of financial discipline.
Turning to the balance sheet, our strong cash position gives us an incredible amount of resilience.
In 2018 we generated $64 million in operating cash, up from $18 million a year ago.
That, combined with the follow-on offering, gives us about $350 million in cash, which puts us in a strong position to flip the switch on selling TASER subscriptions.
Equally important, we have the financial muscle to continue investing in our 4 strategic growth areas to drive ongoing innovation and market leadership.
The guidance we're providing today reflects strength on both the top and bottom line.
As we look at 2019, we expect momentum to build throughout the year, with Q1 sales reflecting a more modest growth rate relative to the back half.
We will continue investing for growth with increases in R&D as a percentage of sales throughout the year.
We plan to partially offset that by reducing SG&A as a percentage of sales.
SG&A as a percentage of sales dropped from 40% in 2017 to 37% in 2018, and we expect to further reduce that in 2019.
Our teams are incredibly excited about our success in 2018, and they're highly motivated to keep the top line growing and maintain the operating discipline needed to drive bottom line results.
And with that, operator, let's turn to questions.
Operator
[Operator Instructions.] The first question comes from the line of Mark Strouse of JP Morgan.
Mark Wesley Strouse - Alternative Energy and Applied & Emerging Technologies Analyst
So Jawad, I think you've done a pretty good job of laying out the, kind of the 1-time items that were weighing on margins in 4Q.
But just a question for the guidance.
How should we think about the -- I guess call it 1-time items associated with VIEVU and their large contract that they have?
Are there any more expenses that we should expect here in the first half of 2019?
And then kind of a quick follow-up to that is your guidance kind of points to EBITDA margin expansion a bit below your kind of long-term targets that you've talked about over the last year or so.
I guess how should we think about that longer term?
Are you kind of stepping away from those targets, or can you reiterate those?
Jawad A. Ahsan - CFO
Yes, great question, Mark.
I'll start with the VIEVU one.
So look, VIEVU was dilutive.
We knew that when we acquired the business and when we had the issue with that one large customer domestically.
It ended up being more of a headwind than we had counted on, and we're still working very hard to get that business integrated and to rationalize some of the duplicative costs and to make sure that it's no longer a headwind going into 2019.
And we're certainly not going to see the level of dilutive costs that we saw last year earned in 2018.
We are expecting still in Q1, I would say, to see some costs as we continue to just rationalize some of the cost base there.
But it's going to be an order of magnitude less than it was in 2018.
And then on your second question, it's also a good question.
What we're looking to do very much is still to drive leverage.
And we're not stepping away from our guidance, but we are, just again, facing this headwind from VIEVU.
And also part of what you saw in our Q4 results was that the TASER 7 ramp costs ended up being higher than we were expecting, and we're expecting to see a little bit of that in Q1.
Mark Wesley Strouse - Alternative Energy and Applied & Emerging Technologies Analyst
Okay, that's helpful.
Thank you.
And then you're mentioning, or I guess your kind of high adjacent markets more this -- in the press release.
Can you talk about the incremental expense associated with that that's kind of baked into your 2019 OpEx?
And then if there's anything high level that you can share to kind of help investors frame the addressable markets for those, that would be helpful.
Thank you.
Luke S. Larson - President
Yes, Mark, I'll handle the first part of that question.
In terms of growing OpEx to support additional markets, we actually have several key members of our team that are working on new market expansion.
And one of the great motivations for them, we actually had quite a few senior individuals on our customer-facing teams opt into the XSU plan.
And so they're working overtime to figure out how to open up these new markets.
So we don't see any great OpEx add there.
I think this is -- we're going to continue to drive leverage in SG&A and still be able to open up some of these new markets.
In terms of the focus of those markets, we really see an opportunity in what we would call very adjacent markets like EMS and fire, and we have teams talking in those.
They're not quite as big as the law enforcement market.
We also have had some interest from additional markets as well.
I'm actually going to kind of keep that pretty tight-lipped for now, just because we don't want to release any competitive intel.
Operator
Your next question comes from the line of Will Power of Baird.
William Verity Power - Senior Research Analyst
Maybe first just coming back to the 2019 revenue guidance and the expected build through the year off of Q1, I guess I'd just be interested in the visibility into the second half, kind of the key drivers.
I guess body camera 3 is part of that.
But any reason why TASER 7 wouldn't continue to build off of Q4 through the first half, and I guess continue to build in the second half.
So I'm just trying to understand the visibility of that second half improvement in revenue.
Jawad A. Ahsan - CFO
Yes, we're expecting TASER 7 production to be fully ramped by about the midpoint of the year, and so what we'll see is a pickup in revenue in the second half.
And then what's going to happen is there will be sort of a forced multiplier effect with AB3.
A lot of those upgrades are also coming up in the back half of the year.
So T7 being fully ramped as well as AB3 upgrades in the back half of the year are going to lead revenue to be the profile we have here in the back half of the year.
William Verity Power - Senior Research Analyst
Okay, and then among the 4 key kind of strategic growth drivers I think you talked about in the presentation, or the release, you talked about records already and pushing for bookings and key customers later this year.
I guess I didn't hear much more on Dispatch.
I guess I'd be curious what you're thinking there and timing from here.
Luke S. Larson - President
Yes, why don't we have Rick take that question?
Patrick W. Smith - Co-Founder, CEO & Director
Thanks, Luke, yes.
Dispatch, we are not releasing a lot for competitive reasons on that point.
It's an area we're pretty excited about.
Stay tuned for some calls later in the year, and we'll provide some more detail about it.
But for now, we're going to keep that one fairly close to the vest.
Operator
Your next question comes from the line of Jonathan Ho of William Blair.
Jonathan Frank Ho - Technology Analyst
So I just wanted to start out, in terms of your marketing expectations around RMS, I know you talked about the second half being in the opportunity time frame, but what magnitude of bookings should we be thinking about?
And can you give us some color in terms of the types of customers you'd be targeting initially?
Patrick W. Smith - Co-Founder, CEO & Director
Yes, I can take that one; this is Rick.
So most of the early bookings, actually, we expect to be as part of the OSP bundles, the Officer Safety Plan bundles, so we included Records in that because we think that the real target market for us are people that -- are agencies that are already using the majority of our ecosystem with TASER weapons, the body cameras and cloud software.
So the real play we see is the opportunity there.
Now, there is some revenue allocation that is allocated towards Records.
I'm actually in a different area of the country from Jawad and Luke.
Jawad, do we -- I assume we're not giving any more details in terms of how that revenue allocation is being handled at this time?
Jawad A. Ahsan - CFO
No, not at this time.
Patrick W. Smith - Co-Founder, CEO & Director
Okay.
So we really view it as part of the overall enterprise sale, and the reason to include Records as a free add-on in that sales, we see the real value, long haul, is in the data, not in the software itself.
So fundamentally, Records software is form-filling software.
It's the forms and reports officers fill out, and we think that no matter how good your form-filling software is, it will largely be a commodity.
And as such, when we see things that are commodity, our general strategy is to have a more aggressive go-to-market plan.
And in this case, we decided to make it free in that bundle.
And the rationale really is that the real value add will be in the automation that's possible by connecting the audio-video stream from the camera to the record management software so that we can begin pre-populating.
And ultimately, over a 5- to 7-year time horizon, we believe we can dramatically cut the amount of time that officers spend filling out forms.
And fundamentally, law enforcement interaction is what my AI team sort of points to as a really great target for machine transcription, because they're very structured conversations.
You know, “Hello, sir?
What's your name?
Where do you live?
What's your date of birth.” And with that sort of structured conversation, to be able to extract that information from the audio-video record and pre-populate it into the printed record is something that will be hugely valuable.
And to just give you an idea, I talked to one major customer in the U.S., and they had spent recently something like a $40 million contract on a record management system over a multiyear time period.
But that same agency spends around $1.6 billion a year on payroll, and their officers are spending about half their time doing administrative tasks.
So the value creation opportunity is for us to automate that $800 million payroll cost that's going to non-value-added bureaucratic tasks.
And so that's where you'll begin to see -- so you will see revenue associated with Records.
It will largely be a function of allocation against the bundle in the early years, and then where it will really kick in is when we add the high-value analytics and AI automation that connects the body cameras to Records over the next 3 to 5 years.
Jonathan Frank Ho - Technology Analyst
Excellent.
Thank you for the color.
And just as a follow-up, when we look at sort of the strengths around TASER 7 and the excitement that you're seeing in the customer base, can you talk about how maybe that impacts OSP?
Are you seeing other customers that have historically been sort of hardware only now want to refresh TASER 7 and look at the broader bundle?
Or like how does that potentially maybe change that mix?
Luke S. Larson - President
Absolutely.
Go ahead, Rick.
Yes, we see a great opportunity every time we get in front of our customers to talk about the total Axon solution.
And so the strength of our portfolio is when all those products are used together.
The agencies see additional benefits.
And so every time we're in talking with a customer about any one of our products, we're kind of highlighting the benefit of the total solution.
Over to you, Rick.
Patrick W. Smith - Co-Founder, CEO & Director
Yes, I would say, so the TASER 7 definitely, it has a much stronger data integration element to it.
Actually, just yesterday I was going over with some of our design team what they did on things like device assignment, which doesn't sound particularly sexy or even the returns process.
But when you're an agency that's deploying thousands of TASER weapons, how you -- having to write down serial numbers and type them into a spreadsheet later, versus now we do it with a mobile app, where you tap it on the device and assign it to an officer, we're doing thousands of these.
It just dramatically improves the experience, and that's all part of that integrated software ecosystem.
And with AB3, that will pair with your TASER 7 and start to allow things like real-time alerting.
So if an officer arms or fires their TASER 7 in the field, that alert can be routed to other officers within the agency or administrators in a service we're calling Aware, which really, to help the agency be better aware of what's actually happening out in the field.
And I'd wrap by saying to me, the most exciting thing coming this year will be Axon Body 3, because I think fundamentally, we're poised for an iPhone moment, meaning when the iPod went to the iPhone, the initial perception was, “Well, my music player now has a phone in it.” And now as you look back at it, pretty rarely people even use the thing as a phone anymore.
It became such a transformatively connected device.
We see similar opportunities in effectively today, we make sort of a nuanced GoPro type of camera.
We make great camera that the officers wear, and they download the information and use it later.
Once LTE kicks in, we'll be able to offer all kinds of real-time services that will sit on top of that hardware platform so the camera becomes something more like an Alexa on your chest as opposed to just a camera you wear to record.
And we think that will open up a whole host of really interesting services, some of which we're already planning for and some of which we think we'll discover once that connectivity comes online and we're out in the field.
And by the way, the significant majority of our customers in the U.S. are on our hardware upgrade program, and so they will get Axon Body 3 sort of like clockwork as part of their subscription, which a really big part of both the customer benefit that they -- we carry them into the future with both hardware and software upgrade features.
And it's great for us because we can plan our road map.
We don't have to sort of plan to indefinitely support the last 3 generations of cameras.
We can move our install base along with us, and that gives us flexibility to move and innovate faster than any of the competitors in this space.
Operator
Your next question comes from the line of Jeremy Hamblin of Dougherty & Company.
Jeremy Scott Hamblin - VP and Senior Research Analyst of Consumer & Retail
I wanted to ask about that.
You mentioned the time to rebuild the TASER gross margin.
Can you give us a better sense, maybe a more specific time frame in which you think you'll get that business back into that 69% to 70% range on the gross margin?
Jawad A. Ahsan - CFO
At this point, Jeremy, that's something we're going to see throughout 2019.
It will successively build.
There's a lot of factors there.
Obviously, we have the ramp costs that we're dealing with in Q4, and we're going to see that in the first half of the year until we're fully ramped.
And then we're also still very much -- we're at the point where we've got trade-in credits that are in the mix, and there's the discounting.
Although we have changed the incentive structure with the sales team to minimize discounting, there's still some early leader pricing going on.
There's some trade-in credits.
And so what we're going to expect to see is throughout the year, those margins will build and, hopefully, exiting 2019, they'll be more on a normalized basis.
Jeremy Scott Hamblin - VP and Senior Research Analyst of Consumer & Retail
Got you.
That's very helpful.
And then just in terms of you've talked about investment, and as we think about our R&D outlook this year, you had a little bit lower number here in Q4.
As we think about 2019 and your R&D investments, how is that going to reflect, I guess, the new product launches, Axon Records coming along?
How should we be thinking about that particular line item?
Jawad A. Ahsan - CFO
Yes, a good question, Jeremy.
So you've seen we've continued to increase our investment in R&D.
We're very excited about the opportunities that are ahead of us, certainly in the markets that we're addressing today.
But there are some new opportunities in adjacent markets, and we're very excited about Records and Dispatch as well.
And what we don't want to do is under-invest and miss out on those opportunities.
And so for 2019, you can expect that our R&D as a percentage of revenue will be slightly above 20%.
And that's up from about 18% in 2018.
It's up from 16% in 2017.
And what we're doing to help offset that, if you look at our SG&A as a percentage of revenue, that's coming down.
So it was 40% at the end of 2017, about 37% at the end of 2018, and we're going to expect to drive that down even further in 2019, closer to about 35%.
And so what we're very consciously doing is driving leverage in our support function costs and reinvesting those dollars into R&D.
Jeremy Scott Hamblin - VP and Senior Research Analyst of Consumer & Retail
Okay, great.
And then just a follow-up related to that question, which is in thinking about Records specifically, in terms of the time frame in which that's going to be a revenue-generating product, can you give us a sense?
In 2020, is that something in early 2020 in terms of revenue generation, or more the second half of the year?
Luke S. Larson - President
Yes, so as Rick was saying earlier, we're actually selling Axon Records today bundled in with our TASER 7 OSP offering.
But we would see that being a contributor in the first part of 2020.
Patrick W. Smith - Co-Founder, CEO & Director
Yes, just to add a little color there, we don't expect that we're going to be selling many standalone deals of Axon Records, because where our solution is particularly strong is in the integration piece of the Axon ecosystem, which it just so happens that's the majority of major agencies are already on.
So you'll see it showing up in these bundled sales, and we'll start recognizing revenue as soon as the product is in general availability with features that meet the rev rec guidelines in our customers' concern to gain utility from those features.
So we expect that to happen late this year.
Jeremy Scott Hamblin - VP and Senior Research Analyst of Consumer & Retail
Right, that was really the question of when that product was going to be recognized as revenue.
But I think we got the answer.
Thank you, guys.
Operator
Your next question comes from the line of Mike Latimore of Northland Capital Markets.
Michael James Latimore - MD & Senior Research Analyst
This is (inaudible) for Michael Latimore.
I have 2 questions.
My first one is like what percentage of your TASER sales were sold on the recurring plan and as updates?
Jawad A. Ahsan - CFO
We're just going to track that down.
We've got that in our shareholder letter.
Andrea Susan James - VP of IR
35% of all weapons sold in Q4 were on our recurring payment plan.
And in the U.S. specifically, it was 48% of new TASER contracts.
And I believe it was almost all T7 was on a recurring.
Michael James Latimore - MD & Senior Research Analyst
Yes, and my second question is like do you have a sense of your backlog of evidence.com seats not activated?
Andrea Susan James - VP of IR
Yes, we do have that.
Generally, about 20%.
Jawad A. Ahsan - CFO
Yes, it's about 15% to 20% of our book seats.
Operator
Your next question comes from the line of Saliq Khan of Imperial Capital.
Saliq Jamil Khan - VP
I have 2 quick questions for you on my end.
The first one is could you give me a bit more granularity on the Axon Fleet 2, either regarding your expected revenue or the margin contribution?
And even more importantly is, are you seeing any competitive pressures from the likes of WatchGuard?
Luke S. Larson - President
Yes, so why don't I start with the back half of your question?
We have really seen demand for Fleet 2 and are just really proud of the kind of market's response and the demand for Fleet.
We sell the majority of our Fleet products just like we do our cameras, where we sell them on bookings or they'll buy on a 5-year contract and then we recognize that over a 5-year period.
Patrick W. Smith - Co-Founder, CEO & Director
Hey, Luke, if I could contribute as well, I would say a couple of years ago, WatchGuard was the clear market leader in in-car video.
And by the way, they're a company we hold in high regard.
But I'd say we've been quite competitive.
Our competitive sales tells us there have been quarters where we've been the market leader on a dollar booking basis, and we continue to feel that the momentum is heading in our direction, so we feel really good about within a year or 2 of launch, we've been able to be a contender for the #1 spot, and we think we only get stronger with time.
Jawad A. Ahsan - CFO
I just want to provide some extra color.
We shipped about 4,000 units in the quarter, and we're expecting in 2019 our quarterly run rate to be at or above that level.
Saliq Jamil Khan - VP
That's very helpful.
Thank you for that.
There's 2 more questions on my end as well.
You may have touched upon the first one, but the Axon Flex unit sales, I noticed that they had declined roughly 3% year-over-year.
Is that because you're seeing some of the sales be cannibalized by your other offerings, or is there something else going on that I may be missing?
Luke S. Larson - President
So at IACP, we announced our Axon Body 3 camera, and so we've been working with a lot of our customers on how we would transition them over to the new technology that's going to be shipping this year.
Patrick W. Smith - Co-Founder, CEO & Director
Yes, this is Rick.
I'm going to add in that in general, I think we've seen the market shifting in favor of the integrated 1-piece body camera versus the 2-piece.
The original concept of Flex was that it would be a head-mounted camera that would track the perspective of the officer.
And what we found is just in practice, officers really do not enjoy wearing the camera on their heads, so they tend to wear it on their shoulders, et cetera, and that ends up really giving you a suboptimal experience because then you have the narrower field of view and it's not ultimately tracking the officer's head.
So I'm continuing to see a trend where officers and agencies are just moving towards the more simplified body camera design that -- both AB2 and now AB3.
Saliq Jamil Khan - VP
Yes, I would envision that as well.
I think the 4 factor and just ease of use altogether for the AB3, this seems a lot better than what I saw with the Axon Flex.
So nonetheless, it's a great product.
The last question on my end, guys, I know, Rick, you had done a ton of work with this in the past.
I believe you continue to do a lot more of this.
If you take a look at the international business, it tends to be a bit different due to these 4 agencies that are out there.
What have you done over the past year or 2 to be able to improve the predictability of your international business?
Patrick W. Smith - Co-Founder, CEO & Director
So the main thing we've done is really hiring dedicated salespeople in market.
And I think we've got a pretty good model of what it takes to open a market.
I don't want to get into detail here because we have competitors on the call that have how we resource markets.
But I think we've got it down to where we're able to replicate that as we go into a new market in a pretty efficient way.
We did just come off a record period in international sales, and we do expect the year ahead, we could really start to see international continue to blossom, really across the world, but I think mainly in Europe or areas we've got our eye on.
I was there in 2015 and '16.
It's been 2 or 3 years, and so we're now starting to see some of those national police forces like we saw in Sweden, and we've got some others that are in field trials with both TASER weapons and cameras.

Your next question comes from the line of Scott Berg of Needham.
Scott Randolph Berg - Senior Analyst
I have one and a follow-up.
I guess first of all, I don't know if Rick or Luke want to answer the question, but can you give us a sense of what you saw from customers in the quarter that were evaluating the new TASER 7 in terms of their willingness to purchase subscription?
I heard Andrea give the metric that the vast majority of the sales in the quarter on the TASER 7 were subscription, but how about maybe a broader comment on the conversations you had?
Luke S. Larson - President
Rick, why don't you take that one?
Well, yes, sure.
So when we -- historically, when we were approaching customers, a lot of the early TASER purchases for M26 and X26 were out of -- they were out of their discretionary funds, usually kind of chunks of cash that they could spend on whatever they wanted.
Now we've effectively positioned the TASER as mission-critical gear.
So the majority of the agencies, especially in the States, have actually come to us with a poll to put that into their operating budget, which really aligns with our subscription plan.
So I would see, over the next 3 to 5 years, we would expect the vast majority of our U.S. customers to buy on a recurring service plan.
Now we do want to keep in mind that they still have some of these discretionary funds, and if that's the way they like to purchase, we're never going to turn away a P.O., but I would see the majority of the customers looking to buy on the subscription plans.
Patrick W. Smith - Co-Founder, CEO & Director
Yes, I would add that as well.
TASER 7's a little interesting in that virtually every sale has a subscription element.
Even if they buy the weapon, there's a subscription element for the docks, rechargeable batteries and software services that they would really need to effectively run the program, even if they bought the weapons outright.
So to my way of telling you, every significant order in the quarter had some subscription element.
And in fact, I can't think of one offhand where the customer came in and basically said, “No, no, I'm going to buy the weapons and only use the subscription for the smaller parts.” There may have been some of that, but the tone of the market's quite different, whereas 3 or 4 years ago when we started offering payment plans for weapons, I would say the majority of customers would come back and say, “No, no, no, I want to buy this the way I've always bought it and pay you 1 time and own it,” whereas now I would say the majority, at least of the larger customers where I'm having personal exposure, they're almost -- well, they're all, that I'm aware of, that I was just talking to, going onto one of these Officer Safety or Certification type plans, where it's a subscription model.
Scott Randolph Berg - Senior Analyst
Got it, helpful.
And then my follow-up would be on in your press release, you mentioned some incremental investments outside of law enforcement, like fire departments, emergency medical or emergency services, et cetera.
Can you maybe quantify what those additional investments or those incremental investments look like here in '19?
And then how about any other success stories in your endeavors outside of law enforcement, outside of the, I think it was the Charlotte Fire Department that was a big win during the year?
Thank you.
Jawad A. Ahsan - CFO
So I'll start with the level of investment.
You can expect that we'll make those investments within the guidance that we've given for R&D, so we've got it to north of 20% for R&D as a percentage of revenue, and that's inclusive of the investments we're making for adjacent markets.
And at this point as part of the overall bucket, it's still relatively minimal.
Patrick W. Smith - Co-Founder, CEO & Director
Yes, I would just add there that what we're mostly focused on is how do we take the same products and feature set we've created for law enforcement and find other enterprise users that would want similar capabilities.
And in fact, this is one where having law enforcement as reference customers is pretty powerful because that's seen by enterprises as a fairly elite, very data secure oriented market where we're the clear leader.
And now we're looking at how we can parlay that leadership into revenue in other markets, where we do it in a pretty scrappy way.
So just building on what Jawad said, it's not something that you will see broken out.
These are nowhere near the level of investment that we're making into major initiatives like Records, Dispatch.
This is really taking the major investments we've made in building these connected body cameras and now taking those into new markets.
So from an SG&A perspective, I think these -- our expectation is that new markets should pay for themselves relatively quickly.
There's not going to be some huge upfront marketing and launch expense.
We're moving to these markets in a pretty cost-effective way.
Jawad A. Ahsan - CFO
Yes, actually, I want to add to that.
I want to give Rick and Luke a lot of kudos here.
Previously, when we thought about getting into new markets, new products, we made pretty heavy investments.
And what we've done recently is really shift to this smaller, scrappier mindset, and Rick and Luke have pioneered these delta teams that you've heard us talk about, where we'll take very small teams of 1 to 3 people and basically have them bootstrap their way into growth.
And we've done that with our drones business.
There's some other new product categories we're getting into where we're doing this.
And it's proving to be -- we are very, very excited about the early returns we're seeing from these new products.
So there are certainly markets for existing products like body cameras and TASERs that we're looking for markets outside of law enforcement.
But then there are also new product categories that we're approaching in a small, scrappy mindset.
Operator
Your next question comes from the line of Steve Dyer of Craig-Hallum.
Steven Lee Dyer - Managing Partner & Senior Research Analyst
A question on the TASER business and then a question on software and sensors.
On the TASER business, I think you touched on a little bit of the gross margin degradation from operating margin of 18.5%.
Would you add back, in other words, some 1-time add-backs.
But if you add those back, what do you feel like a good sort of normalized operating margin in the quarter was?
Jawad A. Ahsan - CFO
So for TASER, we were looking at -- hang on a second; we've got it here -- on a pro forma basis -- so yes, this is part of the issue we have, Steve, is that we're really -- we're no longer breaking out SG&A by segment because a lot of our SG&A costs were -- actually, most of our SG&A costs were allocated to TASER, and it wasn't very meaningful to look at that by segment.
And so we look at our gross margins by segment, we look at our R&D by segment, but SG&A, we really look at on a consolidated basis.
So I would really point you to focus to the TASER gross margins, and that's something we're, like we had said, in the short term 61% to 63% and we expect that to normalize by the end of the year.
Steven Lee Dyer - Managing Partner & Senior Research Analyst
Got it.
I guess where my question's going is not that long ago, a couple of years ago, as recently as that, but the TASER business was a mid to high 30s operating margin business, and it's sort of been gradually declining over the last couple of years.
And again, I calculate 18.5% this year on an operating basis.
But I realize there were a couple of 1-time things weighing on that.
I guess I'm trying to figure out is the TASER business structurally different in any way than it was a couple of years ago, or is pricing different?
I would think if anything, more people on the subscription plan would actually be more profitable.
But is anything going on there that I can make heads or tails of?
Jawad A. Ahsan - CFO
Yes, so Steve, that's very perceptive, and what you're seeing is that the company overall is much different than it was a couple of years ago.
And a lot of the infrastructure that we've added, from an SG&A standpoint, is servicing the entire company, but all those costs have been burdened in TASERs.
So when you look at the TASER operating margins over that period, for sure it's going to have degraded.
But that's not really reflective of what's going on in the TASER business because again, we haven't been allocating those costs to software and sensors, which is why we're really looking at across margins by segment, and SG&A, we look at on a consolidated basis.
But again, I've already given you the guidance for the gross margins on TASERs, so it's taking a bit of a step back as we're ramping up TASER 7, but we expect that's going to normalize throughout 2019.
And we also feel really good about the body camera business.
If you take out the costs for VIEVU, those 1-time headwinds, we're actually, we're very close to breakeven.
Steven Lee Dyer - Managing Partner & Senior Research Analyst
Got it.
That's helpful.
Thanks.
I guess one more question on weapons while I have you.
What's your expectation that the buyers of that product will typically be people who already have TASER devices?
Or do you anticipate sort of any new sort of conquest sales from people on that, I guess, going forward?
Where do you expect to get that growth from?
Jawad A. Ahsan - CFO
I'd like to start with this before I turn it over.
So one of the things that I'm very excited about with TASER 7, so a key part of our strategy has been to shift towards a recurring pricing model with the TASER weapons.
First, we've always talked about the 5-year useful life and how that should be a driver of new sales.
And then we talked about shifting from CapEx to OpEx and really being a line item in the budget.
And for the first time what we're seeing is demand for the new TASER weapon on the merits of the weapon being very good.
So historically, for X2, for X26P, it's been the 5-year useful life, it's been the shift to OpEx.
But now what we're seeing is people actually want the TASER 7 because it's so good.
Luke S. Larson - President
Yes, we think every front line officer should carry a TASER.
It wasn't that long ago that Chicago P.D. had a high-profile incident where they called for a TASER 7 times and they didn't have them on, and then in the wake of that incident, they really made a push to get them on all front line officers.
So we're working on filling out every major city, every white space.
We believe front line officers should have TASERs.
And then internationally, we're also seeing a big opportunity where historically we've seen a smaller percentage of forces, just a percentage to buoy, and we're now making strides in positioning, “Hey, this should be carried by every officer.”
Steven Lee Dyer - Managing Partner & Senior Research Analyst
The last one for me, just as it relates to body cams.
They've been out there now for a few years, I'm sure to the point that you're starting to see some opportunities for renewal.
What do you see when those people come up for their first renewals?
Some of the early adopters on body cams?
Is there any attrition to speak of or any color there would be great.
Thanks.
Luke S. Larson - President
Yes, one of our metrics for last year was actually on churn and retention, so we're laser-focused on every deal, ensuring that when they come up for renewal, they stay on the Axon Network.
We've not rested on our laurels.
We're investing in making these products even better and offer more capabilities like the AB3.
So both Rick and I are taking an active role in meeting with major cities.
This week we're both going to be out at different major cities along with our Chief Revenue Officer, not only talking about the body cameras, but talking about the entire OSP 7 offering with TASER 7 and Records.
But we feel very, very confident that we've got a sticky solution with the entire Axon offering.
Steven Lee Dyer - Managing Partner & Senior Research Analyst
So with all that said, are there any stats that you're able to share just around any attrition or any renewal percentages, et cetera?
Patrick W. Smith - Co-Founder, CEO & Director
I'm sorry, could you repeat that?
Your line is really staticky.
I couldn't make that out.
Steven Lee Dyer - Managing Partner & Senior Research Analyst
Yes, I guess what I'm looking for is as some of the early adopters come up for renewal on the body cam, just any anecdotal or quantitative numbers that you've seen back around attrition or renewal or anything like that to suggest that it's a long-term sticky product?
Jawad A. Ahsan - CFO
Yes, so for the first time -- so last year we changed our bonus metrics.
They were previously all commercially focused.
And for the first time last year, we introduced some profitability metrics.
We also introduced some usage, and we had churn as one of the metrics.
And it was less than, I want to say a third of a percent.
It was practically 0, and we had, I want to say, about 20 different accounts up for renewal.
And so it's been a very sticky product.
Actually, a lot of what we're seeing is that the customers don't even go the full 5 years.
They end up renewing early and adding scope, adding users and scope of work to their contracts.
Luke S. Larson - President
Yes, I would also offer when they go on the -- when they adopt Axon body cameras, we're not only offering them cameras, we're going into their operating workflow, where the officer gets to learn the product.
They also, a day in the life, they're docking that in a dock that's infrastructure that we actually install onsite.
And then all of that evidence uploads to evidence.com, which is now we have over 40 petabytes of data on evidence.com.
So we want to continually provide new value to the agencies, but we also have really cemented ourselves in that workflow with the infrastructure that we've put in place as well as just the amount of data that they're uploading to the SaaS system.
Patrick W. Smith - Co-Founder, CEO & Director
Yes, this is Rick.
Just to put a finer point on it, of all the agencies large enough to be on my radar screen last year, there was only 1 that did not renew, and that was not a customer that -- it was a customer that had a small T&E, meaning a small test number of units that they were not actively using.
So that's the sort of customer you'd expect wouldn't renew if they got a small number and for whatever reason didn't deploy them.
But every significant customer with any decent number of cameras on the network renewed last year.
So I should knock on wood when I say that, but we're very happy.
Customers are finding utility and they're far -- we saw a lot of customers last year upgrade early because they wanted to add, whether it's a TASER 7, whether it's adding Fleet or any of the other new features.
We're seeing that that is a very common phenomenon.
And once agencies do go through adding something onto their contract, it's pretty universal.
I'm looking at my team here to make sense.
Actually, I said that most of the time if they're going to go through procurement, they want to coterminate and extent to another 5 years so they don't have to keep going through another procurement process unless they want to because we've created another value prop for them to come in and increase it.
So punch line is it's working, I'd say, better than I could have anticipated when we got into this business.
Operator
Your next question comes from the line of George Godfrey of CLK.
George James Godfrey - Senior VP & Senior Research Analyst
Question one for you, Jawad.
Adjusted EBITDA is $82.5 million at the midpoint, and I'm just thinking that in 2018, adjusted EBITDA came in at $61 million.
Free cash flow was $47 million, so a 77% conversion rate.
Would you expect a similar conversion rate on your adjusted EBITDA in '19?
Jawad A. Ahsan - CFO
Directionally, yes.
I think it will probably -- so what we were generally expecting to see a bit of an impact on cash with TASER 7 because most of those sales are obviously on subscription versus the upfront, like book-and-ship model for the previous weapons.
But we haven't seen as much of an impact because we also now have had customers on these recurring deals for some period of time, and like there's with these -- them making their -- with that base building, it's less of an impact.
So I'd say directionally, it's going to be about the same.
It may be slightly lower, but about the same.
George James Godfrey - Senior VP & Senior Research Analyst
Got it.
And then the second question is more a high level.
I read through the announcement again just now for the Swedish Police Authority and taking the Axon Body Camera.
I'm just curious.
What -- your sales pitch is probably very similar across countries, but I'm just curious.
What did Sweden latch onto, or what pushed them over the goal line versus other countries that you're still having to work through to get them to sign a contract?
Luke S. Larson - President
Yes, so in international, we have a slightly different sales dynamic.
In the States, we've got these municipal agencies that are much faster sales cycle.
There's also a lot of now earned comfort with going all in on the cloud.
In Europe, in Continental Europe in particular, we're still working with some countries on issues around data sovereignty.
In some kind of mid-tier markets, they actually have infrastructure gaps, like they might not have access to constant connectivity for like a cloud-based solution.
And so in Sweden, we have a great kind of reference customer.
They're close to Greater London Metropolitan Police and other big agencies in the U.K. And so I think all of those factors made it very compelling for them to go onto the Axon Network.
George James Godfrey - Senior VP & Senior Research Analyst
So Sweden is more comfortable with their infrastructure data connectivity versus, say, in Italy or Germany?
Luke S. Larson - President
In Germany in particular, there is a lot of sensitivity around working with German providers for technology and infrastructure.
We've hired an on-the-ground German customer-facing rep.
We are still in the process of developing the right technology and implementation partners in Germany, and those are -- kind of slow down the adoption cycle.
Andrea Susan James - VP of IR
Operator, before we go to the next question -- we can go a little bit, a few minutes over.
I just wanted a quick point of clarification of something that's been said in the last couple of minutes, and it's pretty clear in the shareholder letter that the gross margin guidance for Q1 and the rest of the year is 61% to 63% for the whole company, not the TASER segment.
So I just wanted to make sure that was clear.
Okay, next question, please.
Operator
Your next question comes from the line of Keith Housum of Northcoast Research.
Keith Michael Housum - MD & Equity Research Analyst
Guys, as we're not going to have a TASER 7 acceptance, I know there's about 11% acceptance rate in the quarter, and I noticed you guys are saying it's going to ramp up throughout the year.
Can you provide a little bit of color on, I guess, how fast you expect it to ramp up, and do you expect to perhaps exit FY19 with 100% TASER 7 sales going forward?
Luke S. Larson - President
We wouldn't expect 100% TASER 7 sales.
20% of our business is going to come from international, and that's going to be a slower market to adopt TASER 7 as we clear all of their regulatory things that we need to have in place.
In the U.S., we would see -- we think the majority of the deals will end the year with TASER 7 being our #1 seller.
We will have some agencies that may be laggards or have price sensitivity, in which case we've got a great offering in the X26P, still.
Keith Michael Housum - MD & Equity Research Analyst
Got it.
And then Jawad, if I look at the profitability of a T7 under the subscription plan, I noticed in the release, you guys talked about 45% of the revenue being recognized at the time of sale.
Will it be the profitability at that point in time?
It would be same percentage as the sale or no?
Jawad A. Ahsan - CFO
So there are actually -- there are 2 models that we sell the TASER under.
One is a $40-a-month plan; one is a $60-a-month plan.
The 45% is for the $60-a-month plan.
The $40 plan actually has more revenue upfront.
It has about 75% of revenue upfront, and that's because on the $60 plan, more of the revenue gets allocated to the software components.
And so the profitability will depend on the mix of the 2 plans.
But overall, what we expect for the entire company is that the margin -- what we'll see is that the margins will then start to tick up on the software side.
Keith Michael Housum - MD & Equity Research Analyst
So maybe if I ask the question a little bit differently.
So if, let's say the $60-a-month plan, $60 a month, 45% of the revenue is recognized at that point in time.
Does that mean that 45% of the cost is also recognized at that point in time?
Jawad A. Ahsan - CFO
No -- well, the -- no.
The costs for the weapon will be recognized upfront, and it would see less revenue than it would see under the $40-a-month plan.
So the margins would actually be less if we have a higher mix of the $60-a-month plans.
Operator
Your next question comes from the line of Glenn Mattson of Ladenburg.
Glenn George Mattson - VP of Equity Research
I know it's a really recent event, but I'm just curious to see if you guys are hearing anything in the field out there, but the recent Supreme Court ruling that prohibits excessive confiscation in the terms of asset forfeitures and what that would mean for police budgets going forward, and especially in light of the fact that it's kind of a major price increase for your next -- the current Officer Safety Plan.
So if you're going to continue to see success with that program, then I guess you'd be taking share from a shrinking budget, potentially.
So just generally your thoughts on if you're hearing anything yet or what you think you might hear down the road from that kind of a ruling.
Patrick W. Smith - Co-Founder, CEO & Director
Yes, so this is Rick.
We've seen no real impact from it to date.
I would say this is one advantage of getting into the annual budgets.
The things that get hardest hit by those asset forfeiture would be the 1-time purchases where agencies have an event that leads to some confiscated assets that leads to some money that they can buy things with.
That's overall a relatively small portion of their overall budget, and that's more, again, just the things that they buy one-off.
As our business has become ever more integrated into the budget line items, we've become less susceptible to those sort of whims of fate based on what they may or may not have had in terms of confiscations recently.
So we haven't seen much of an effect, and I don't anticipate there to be much of an effect, especially given the shift heavier to subscription.
Operator
There are no further questions at this time.
I would like to turn the call over to Rick Smith for closing remarks.
Patrick W. Smith - Co-Founder, CEO & Director
