Terry Gregg - CEO
Thanks, Steve. Joining me today are Kevin Sayer, our President and Chief Operating Officer; Jess Roper, our Chief Financial Officer; and Steve Pacelli, you just heard from, our Executive Vice President on Strategy and Corporate Development.
As we just held our Q4 2013 earnings call in late February, today's call will be largely a financial update with Kevin reviewing our first quarter 2014 financial results providing a brief business update. I will then follow with some concluding thoughts. Kevin?
Kevin Sayer - President & COO
Thank you, Terry. We'll start with the financial update.
DexCom generated $46.7 million in product revenue for the first quarter of 2014 compared to $27.8 million for the same quarter in 2013, an $18.9 million or 68% increase.
Sequentially, product revenue for Q1 of 2014 decreased 9% from the prior quarter, an improvement over the 12% decrease we experienced from Q4 2012 to Q1 2013. This seasonality is not unexpected as annual insurance deductibles reset and flexible spending accounts are largely unfunded in the first quarter, requiring patients to spend more out-of-pocket dollars to obtain our products.
Total revenue for the first quarter of 2014 was $47.1 million compared to $29.6 million during the same quarter in 2013. Our product gross profit totaled $29.8 million, generating a product gross margin of 64% for the first quarter of 2014 compared to product gross profit of $15.4 million and a product gross margin of 55% for the same quarter in the prior year.
Sequentially, product gross margin in Q1 2014 decreased slightly from the prior quarter. The decrease is attributable to lower product sales during Q1 and a slight shift in our mix of durable and consumable sales resulting from an increase in replacement transmitter sales. During Q1 2014 our mix between durable and consumable products was approximately 32% durable and 68% consumable.
Consistent with prior periods, we anticipate that margins will improve over the course of the year as volumes continue to increase, particularly consumable product sales.
Some final thoughts on our product revenue and gross profits. ASP for sensors has stayed consistent at approximately $7 per sensor and the ASP for our hardware continued at approximately $850 per starter kit. Q1 2014 also represents the first quarter where we have seen a significant increase in standalone transmitter sales. And the ASP on a standalone transmitter is between $400 and $500, depending upon the payer mix during a given quarter. Finally, our international business continues to exceed our expectations and, in the first quarter, grew faster than our domestic sales.
Turning to our expenses, our total operating expenses for the first quarter were $42.1 million compared to total operating expenses of $27.4 million during Q1 of 2013 and $36.4 million for the preceding quarter. The major component of this increase relates to non-cash share-based compensation expense, which is largely tied to the performance of our stock price through the end of March 2014. We note that our share price more than doubled from the end of Q1 2013 and increased 17% during the first quarter of 2014 alone. As a result, our total non-cash equity-related charges for Q1 2014 were $9.9 million compared to $7.1 million in Q4 2013 and compared to just $5.3 million in Q1 2013.
Research and development expense totaled $14.5 million for Q1 in 2014 compared to $9.3 million in Q1 of 2013 and $12.6 million in Q4 of 2013. The year-over-year increase in R&D expense includes a $2.1 million increase in non-cash equity-related expense.
The remaining increase relates to continued investments in the product pipeline, focusing upon increased accuracy, improved connectivity, patient convenience, and lower cost with our ultimate goal of replacing fingersticks.
For example, during Q1 2013, we were not running any major clinical studies and had no open submissions with the FDA. Compare that to Q1 2014, where we conducted a number of clinical studies related to future technology; new sensors, new algorithms, enhanced labeling, cellular connectivity, and general product improvements. And we have a number of pending submissions with the FDA at this time, including DexCom SHARE, the DexCom G4 system for professional use, the SweetSpot cloud-based system, and several others. We believe all of these efforts will ultimately lead to a better experience for our patients and enhance our future growth and profitability.
Sequentially, R&D expense was up 15% with 66% of the increase, or $1.2 million, centered in incremental non-cash equity-related expense. Selling, general, and administrative expense totaled $27.6 million in Q1 of 2014 compared to $18.1 million during the same quarter in 2013, an increase of $9.5 million. SG&A expense for the preceding quarter was $23.8 million, again compared to $27.6 million this quarter.
The increased SG&A expense relates primarily to additional headcount for our commercial infrastructure as we scale the business for continued revenue growth. We started 2013 with 48 sales territories. We now have close to 90 sales territories, adding 20 new territories near the end of 2013 and in early 2014.
In addition to the increased number of feet on the street, we've also added corresponding in-house infrastructure to support this growth. We continue to make significant investments in personnel to manage our payer and distributor relationships. Our headcount in this group has more than doubled since the beginning of 2013. This team has been extremely successful over the past several months as continue to secure more and better direct contracts with payers, strengthen relationships with our current distributors, and lay the foundation for CGM to be covered as a pharmacy benefit.
Finally, the increase in SGA expense year over year includes a $2.3 million increase in non-cash share-based compensation. Sequentially, non-cash share-based compensation expense increased by $1.3 million.
Our net loss for the first quarter of 2014 totaled $12.5 million and included $12 million even in non-cash expenses centered in share-based compensation, depreciation, and amortization. Absent these charges, our net loss would have been approximately $500,000 for Q1 2014, down from the preceding quarter due to the seasonal sequential decline in our product revenue and our investments for future growth. But, this compares quite favorably to a cash-based net loss for Q1 2013 of $3.9 million.
Our loss per share for the quarter was $0.17. It is worth noting that, while our loss per share was higher than consensus, the street consensus OpEx number for Q1 was actually less than our Q4 2013 OpEx spend. While we do not provide detailed P&L guidance, we did state during our last call that we entered Q1 with an additional 20 sales reps and we provided guidance that we expected R&D expense for 2014 to be up between 10% to 20% versus 2013 and we anticipated an increase in SG&A expense of approximately 20% to support our growth. Additionally, we should clarify that the expense guidance we gave during our last call did not include the significant increases in equity-related expense that I just discussed.
In conclusion, we are very pleased with our first quarter financial performance. Our revenue growth is unparalleled. We continue to make significant investments on our commercial infrastructure and our product pipeline to position DexCom for its future long-term objectives. On top of that, our cash-based profitability continues to improve as we develop a new category and seek to disrupt an entire industry, not just build a company or a product line.
With respect to our balance sheet, we ended the first quarter with $57.4 million in cash and marketable securities, up $2.8 million sequentially. And, with our continued debt availability, we are quite comfortable with cash position.
Finally, we remain very comfortable with our current full-year revenue guidance at this time. And, consistent with our past practices, we will evaluate our range at the end of the second quarter and expect to provide an update on our next call.
Now, for the business update. As you know, in February, we received FDA approval of an expanded indication for our G4 PLATINUM to include patients as young as two years of age. We began taking orders for our pediatric product immediately upon approval and we completed our initial shipments to patients within a matter of days. We are very pleased by the initial response of parents and practitioners to the pediatric product offering and have seen the percentage of orders from pediatric patients continue to grow to approximately 20% of our current pipeline opportunities.
However, as we've learned, we have a lot of work ahead of us. Since the approval, we've met with a number of pediatric endocrinologists in the field and at our headquarters in San Diego to better understand this market. While many of these clinics are very excited for the pediatric opportunity, we believe it will take time to properly educate parents and caregivers about the benefits of CGM generally and about the superior performance of our system, more specifically, to grow the pediatric market to the level where it should be.
We continue to have an active dialogue with the Food and Drug Administration regarding our current filings, the major ones being the DexCom SHARE system and the expanded indication for G4 PLATINUM for professional use. We believe both are in their final stages of review.
As you know, in March we received a warning letter from the FDA resulting from a November 2013 inspection of our facilities. The warning letter cites administrative deficiencies in our MDR reporting. There were no sanctions levied by the FDA and the warning letter does not impact our ability to manufacture and sell our product nor does it affect any of our pending or future submissions for product approvals. We are pleased to report that within three weeks of the receipt of this warning letter, we submitted all materials we believe are necessary to demonstrate to the FDA's satisfaction that we are in compliance with our reporting obligations and we expect to close out the warning letter in due course.
Turning to our future CGM product offerings, we remain focused on increased connectivity and convenience as a near-term goal and replacing fingersticks as our primary long-term objective. And we continue to work on both Gen 5 and Gen 6 in an effort to achieve these goals.
As we continue to advance our technology, we were very pleased to learn just last week that the FDA is formulating a new expedited access PMA program for medical devices that address major unmet clinical needs. This program will feature earlier and more interactive engagement with FDA staff, a collaboratively-developed plan for collecting data to support approval, reduced pre-market requirements, and a priority review. While it remains to be seen whether and to what extent CGM will apply, this program certainly appears to be a significant effort by the FDA to further the availability of lifesaving and life-changing products for patients. And we view this as a big step forward.
Shifting to our integration partnerships, both Animas and Tandem continue to press forward with final development, testing, and regulatory matters with their respective sensor-augmented pump systems and we continue to assist them in these endeavors when asked.
I would now like to turn the call over to Terry for some concluding remarks.
Terry Gregg - CEO
Thanks, Kevin. I want to start my comments by reflecting on something reflecting on something Kevin said earlier. At DexCom, we are developing an entirely new category, seeking to disrupt an entire industry.
There are some 25.8 million people in the United States living with diabetes; 1.5 million to 1.75 million with type 1, 7 million undiagnosed, and 80 million designated with pre-diabetes. Research published earlier this year showed a 70% increase in diagnosis of type 1 diabetes in children under the age of six during the period from 1985 to 2004. Expanding that globally, over 382 million people are afflicted with diabetes and that number is expected to pass 592 million in the next 15 years.
What do all of these people have in common? They all suffer from the inability to adequately regulate their glucose levels. Why? Because episodic fingerstick measurements simply aren't good enough.
During the last decade the number of people in the United States with insulin-treated diabetes rose by more 50% and today it is estimated that one-third of patients with diabetes use insulin. But, as insulin use has increased, so has the frequency of sever hypoglycemia.
In fact, it is estimated that approximately 100,000 emergency room visits and 30,000 hospitalizations occur each year in the U.S. due to hypoglycemia. During the period from 2007 to 2011, approximately 9.2% of emergency room visits were for insulin-related hypoglycemia. Severe neurologic sequelae described as shock, loss of consciousness, seizure, associated injury or fall, and hypoglycemia-altered mental states were documented in more than 60% of these cases. And almost a third required hospital admission or transfer to another facility. With the average cost of a hospital admission for hypoglycemia at $17,000 and 30,000 admissions per year, the healthcare bill for this is over half a billion dollars and growing. Adding to the potential problem, there are over 400,000 new insulin users each year. You get the picture.
So, why am I telling you this? Because DexCom is the leading company in the world addressing the challenges of maintaining adequate glucose control. Fingersticks can't do it alone, neither can an insulin pump.
So, when you look at DexCom and you look at our current product offerings of our robust pipeline, what you see is the evolution of an entirely new category in a market with enormous unmet needs. We continue to believe that simplicity, patient convenience, and expanded connectivity, paired with our superior sensor technology will enable us to maintain our leadership position in the CGM market. We are here now, investing in tools to make diabetes management less complicated, less burdensome.
We are not here solely as an accessory to an insulin pump or as a component to an artificial pancreas. And while we certainly are supportive of the efforts to develop an artificial pancreas, in fact we are the key enabling component of virtually all artificial pancreas research being conducted around the globe, we believe we also have a duty to support the vast majority of patients who will either not opt to use this technology due to the complexity or will never have access to it due to cost. These patients deserve better tools to manage their glucose levels as well. And we intend to develop products to meet the needs of all patients.
There is growing consensus that transitioning to outcomes-based payment is fundamental to driving cost-reducing innovation among providers and achieving a financially-sustainable healthcare system. Most everyone agrees that we must migrate from a largely fee-for-service system to one focused on delivering the best patient outcomes at the lowest possible cost.
Medical device companies such as ours need to be cognizant of this as we approach R&D. We will be successful only to the extent that we generate true cost-reducing innovations. We believe our strategic initiatives such as superior accuracy and performance to obtain fingerstick replacement, open connectivity, miniaturization and, ultimately, cost reduction will set DexCom apart.
Our CGM First message has continued to change the behavior of healthcare practitioners to help them better understand glycemic variability and how to manage it more effectively. I have stated on many occasions that diabetes is a mystery to the patients who deal with it every single day and have to act dozens of times each day to address the challenges of glucose control.
This evolution has never been fast enough for me. Although, when I became CEO in 2007, the CGM market was negligible and today it is approaching 10% penetration of the U.S. type 1 patient population. I'm, of course, proud to say that DexCom has a majority market share.
Thank you and, with that, I'll turn it over for our question and answer session.
Operator
Thank you. We will now begin the question and answer session. (Operator Instructions). Tom Gunderson, Piper Jaffray.
Thomas Gunderson - Analyst
Hi. Good afternoon, everybody. On the comment on transmitters being meaningful for the first time; is that a slow rise or did that have something to do with last year? Especially in first quarter, a lot of people upgraded to Gen 4, got a whole transmitter, and now it's a year later. In other words, should we look for higher transmitter sales for the rest of the year or was this one-off event?
Kevin Sayer - President & COO
We believe there will be higher transmitter sales over the course of the year, Tom. Remember, when we launched this, the labeled indication for it is six months. Our transmitters have been quite honestly lasting longer than that. So, this rise in transmitter sales is actually a bit delayed over what we thought would happen. So, yes, we look for that to continue over the course of the year.
Thomas Gunderson - Analyst
Got it. Thanks, Kevin. And my last question is; can you comment a little on competition to the extent that we're getting a little bit more media attention, both on Medtronic and Flash?
Terry Gregg - CEO
Yes. I mean the only thing I can say, Tom, is that if we look at what we did in the first quarter, we obviously did not feel much pressure, in my opinion from a competitive landscape, either domestically or internationally. I mean record quarters on both the U.S. as well as OUS. So, that would be about the summation of my comment.
Thomas Gunderson - Analyst
Okay. Thank you. That's it for me, guys.
Operator
William Plovanic, Canaccord Genuity.
William Plovanic. Great, thanks. Good evening. Can you hear me okay?
Terry Gregg - CEO
Yes.
William Plovanic - Analyst
Perfect. So, just a couple questions. First, just pediatric; how is the strategy different for pediatric? I think you told us it will roll out a little slower. But, how do you approach that market differently than your current adult population?
Kevin Sayer - President & COO
You know, Bill, Terry and I have both been out and visited pediatric clinics and we're approaching them with the same sales team that we approach the adult ones with. What we both noted is we haven't been there before. We've not been an active presence in those clinics. We've complied with our labeling by not actively pursuing a lot of those.
So, while they're familiar with CGM, there's an educational component as we get parents, physicians, other caregivers up to speed and get them used to the experience of DexCom CGM. Even if they've prescribed a few, they're not ready to move to many yet until they get a little more experience with us. So, it's kind of like going into new turf, for lack of a better example. We're kind of starting from scratch.
William Plovanic - Analyst
But you did say -- I just want to make sure I'm clear -- that 20% of your patients in the quarter were pediatric?
Kevin Sayer - President & COO
No, I said 20% of the pipeline, of our open pipeline.
William Plovanic - Analyst
So, as I think of the quarter, I think historically you're running around 10% for ped's. Did you move off of that? Has that increased a lot?
Kevin Sayer - President & COO
Somewhere between 10% and 20% would be a good number at this point in time.
William Plovanic - Analyst
That's a nice tight range. Thank you. And then, if we look at the quarter, that was a very impressive durable number. And I think what we're all going to try to find out or at least try to figure out is; how much of that is new patients? How much of that is transmitter upgrade?
And I know you won't answer the question so I'll ask it this way. One, what type of year-over-year growth did you see in your new patient adds? And, two, is there any type of mix that you might share with us from a revenue component? You know, of that, roughly $15 million in durables, 70% of it was new patient versus upgrades, transmitters, receiver upgrades, all those types of things.
Kevin Sayer - President & COO
You were correct the first time. We will not share the new patient changes. About the guidance between upgrades and new patients, certainly on the kids' side, we've said in previous calls that we typically run at a 70%-30% ratio over time. It may fluctuate more one quarter to another based on deductibles. I think this quarter is relatively typical of what we've seen in the past. The increase in the durable sales really relates to more transmitters than a shift in new patients and upgrades or anything like that.
William Plovanic - Analyst
So, but I mean inside that durable number, kind of what's the mix of new patients to the therapy, just to the therapy versus your existing customers, they're upgrading? So, is $5 million of this transmitters and upgrades and what have you of the $15 million?
Steve Pacelli - EVP, Strategy & Corporate Development
What Kevin was saying was that, again, there's a 70-30 split consumable to durable. But what he's also saying is that we've historically run close to the same split within new patients to upgrade patients, somewhere between 20% to 30% of any quarter is going to be upgrade patients. The durable revenue is going to be upgraded patients.
William Plovanic - Analyst
So the change in the mix this quarter would be because of the increase in the replacement transmitters.
Steve Pacelli - EVP, Strategy & Corporate Development
Right. The bump up to closer to 32% of durable revenue this quarter was attributable to increased transmitter sales. That's right.
William Plovanic - Analyst
That's very helpful. Thank you very much. Then, last question, if I may, is just; have you seen any change in your attrition rate and anything you'd like to quantify with us? And that's all I had. Thank you.
Kevin Sayer - President & COO
No, things look the same as what we said at year end. The attrition rate, certainly, on G4 PLATINUM system is much better than it ever was on SEVEN PLUS and we continue to see good reorder patterns.
William Plovanic - Analyst
Great. Thank you very much.
Operator
Ben Andrew, William Blair.
Ben Andrew - Analyst
Good afternoon. Just following up on that same topic. If I was correct in our modeling, there was probably about $4 million of hardware replacement revenue in the fourth quarter. So, that change in percentage of the total this quarter would suggest something more like $6 million or $7 million of hardware replacement for existing patients. Is that in ballpark?
Steve Pacelli - EVP, Strategy & Corporate Development
We've given you as much as we're going to give you.
Ben Andrew - Analyst
Okay. That's fine. We'll try something else. So, let's talk about the SEVEN PLUS patients who chose not to upgrade for whatever reason. Do you feel at some point do you get another shot on goal with them with the improved accuracy of the G4 or for whatever other reason?
Kevin Sayer - President & COO
You know, I think with some of them we will. One of the reasons some of the patients don't upgrade, and again we've seen this as we look at the various age segments of our population, there are some age segments that tend to drop off more than others. And some of those who chose not to upgrade may have chosen not to upgrade for other reasons and may come back.
We see a lot of our patients who had dropped off SEVEN PLUS for years, when we launched Gen 4, come back to us and become patients again. And we actually count those as new patients because we lost them for a couple years. And, Bill, I think as we come out with our new technologies, again with more accuracy, with more connectivity, with stuff that's smaller, I think a lot of the patients we've lost will come back.
Terry Gregg - CEO
Yes. And I would just add to that in terms of the age demographics, obviously we continue to push at a level to get reimbursement from the Medicare system. And some of these patients, unfortunately, have moved from having traditional third-party payer coverage to Medicare coverage and, if they're on fixed income, there's been some challenges there. But we always look forward to the opportunity to better serve them in the future as well as we push that agenda at the highest levels in CMS as well as in Congress.
Ben Andrew - Analyst
Okay. And then, Kevin, maybe you could talk a little bit about the gross margin sequentially. Obviously, you had made huge progress last year. Volumes in the first quarter we know would be lower. Where do you see that trajectory over the course of the year? Do we actually get closer to that 70% range? Or can you give us some thoughts?
Kevin Sayer - President & COO
Yes. We think we'll move up from here, Ben. We were 66% in Q4 with the large revenue number that we hung up there. And we're quite confident they'll continue to go up over the course of the year. A lot of that is volume-related as we can apply more costs to more stuff that goes out the door and as we get our other improvement programs in place.
Our target margins for our sensors has always been in the 70% to 75% range. And, while we're running at 64% to 66% the last two quarters, it's pretty obvious our sensors are there within that range and we just need to look at ways to keep pushing them up. So, we think we'll get improvements. We're not going to sequential 10-point improvements like we did last year but we can see sequential improvements as we go over the course of the year.
Ben Andrew - Analyst
Okay. And then last question for me. Can you give us some rough sense of what the margin is on hardware? I suppose we can back into it if we use that range for sensors but is it a 10-point or 15-point difference?
Kevin Sayer - President & COO
It's closer to 50%, Bill, when all is said and done.
Ben Andrew - Analyst
Okay. Thanks a lot, guys.
Kevin Sayer - President & COO
Ben. I'm getting all my guys messed up. I'm sorry.
Ben Andrew - Analyst
No worries. Thanks, Kevin.

Unidentified Participant
Hi, this is Robbie Markussen (ph) for Mike. Congrats on the quarter. Can you talk about, I know you touched on it briefly, but maybe just what you're seeing in terms of Medtronic competition with the 530G system? And how have G4 sales trended in Medtronic pump users?
Kevin Sayer - President & COO
We grew 67% this quarter. And that would speak to the strength of our business and how well we did. We certainly hear a lot of Medtronic 530G noise but I think our 67% number supports itself.
With respect to Medtronic pump users who use G4 systems, there are a lot of them. It represents a significant piece of our pump patient base, Medtronic pump patients who use G4 sensors, and they're very happy. So, numbers speak for themselves.
Unidentified Participant
Okay, great. And maybe just a follow up. You've gotten some pretty good reimbursement on type 2 patients recently. Can you talk about trends and what you're seeing there? And are they increasing as a percentage of your base and where are they right now?
Kevin Sayer - President & COO
We attempt to get any insulin-using patient covered in all the contracts that we enter into and we have had some good success in getting that. Type 2's haven't become a real large part of our business but it does continue to grow.
I think the most encouraging thing about the type 2 business that I've seen in my travels and the anecdotal stories we've heard; we have a huge impact on these patients because, once they can see, even if they're insulin using, once they can see the effect of the diet and the activities and the other things they do on their glucose levels, they can make some pretty radical changes that have very immediate outcomes. I've talked with people in the field who've seen type 2's go from an A1C of 10 down to 6.5 very rapidly just with changes in diet and activity. And then they get off some of the other compounds.
So, we're very excited at the opportunity and the results it provides. It's just going to take us awhile to grow it. But, no, it is good. It will be a great market for us over time.
Terry Gregg - CEO
And I would just add, again, when we look at the number of new insulin starts, some 400,000 a year now, obviously the majority of those patients are type 2 patients that have, for whatever reason, migrated either insulin in addition to oral agents or gone directly to insulin because the oral agents were not sustaining. That gives us yet another bolus of opportunity as we look at our product configuration and really build some products in the future directly for patients with type 2, particularly those on insulin. But we certainly wouldn't exclude and the data suggests that, even if you're on oral agents with type 2, you can benefit from CGM.
Unidentified Participant
Thanks.
Operator
Raj Denhoy, Jefferies.
Raj Denhoy - Analyst
Hi, guys. Good afternoon. I wonder if I could ask a couple questions. First, on the operating expense lines, I think you did a fair job of explaining about the heavier stock-based comp in the quarter. And I'm curious about how we should think about the progression of expenses as we move through the year, particularly as I think consensus numbers have you guys getting, at least on an operational basis, or really I should say an earnings basis, positive by the end of the year. Is that in keeping with what you guys are seeing?
Kevin Sayer - President & COO
Last year, by the end of the year, we were cash flow positive from operations when we dropped all the non-cash charges from our P&L. And our goal this year was to grow that cash-based net income at a significantly higher rate than we grew our top line. We achieved that in the first quarter, going from almost a $4 million loss in the first quarter of last year, net cash loss, to a $500,000 net cash loss in the first quarter of this year. And we hope to see that improve over the course of the year.
With a GAAP perspective, when you've got a high end of a range of $225 million in revenue and 65% gross profits with non-cash expenses in excess of $12 million a quarter, GAAP profitability is not happening this year. And that's not been our goal for a while. We would look towards that in 2015. Again, if the equity comp number continues to be so high, GAAP profitability may be pushed down a bit. But we focus very heavily on that cash profitability number and make sure we're adding more the bank account than we're spending. And we saw that this quarter. So, it was good.
Raj Denhoy - Analyst
No, no. Yes, I totally get that. Just in terms of just making sure that we model it correctly and I guess we do -- I think everybody does have you, or most people have you, getting EPS profitable by fourth quarter on a GAAP basis. But, if I'm hearing you correctly, we shouldn't be assuming that, given the non-cash expenses.
Kevin Sayer - President & COO
Well, yes. If everything were the same non-cash-wise, I think we could be close to getting there. But, with the significant increase in non-cash expenses that we're experiencing, again due to the stock price and stuff, it's going to pretty hard.
Raj Denhoy - Analyst
No, okay. I get you. Maybe just a couple on the product side. I think you've been increasingly talking about this product called SHARE, which I guess is one of the features that's going to be on the G5. And I'm curious if there's any updates on the timing of that. It sounds like it's at the FDA.
And then, subsequent to that, when it does get approved, really any expectations run with it that it could be as positive as a catalyst as we've seen with G4 and some other advances?
Kevin Sayer - President & COO
It is at the FDA and, as we said in our comments, we think we're on the homestretch here. Knock on wood. We certainly won't give a date or speak to it.
Again, the SHARE system is our first venture into mobile connectivity, paring the receiver inside a cradle with an Apple device and then sending data to secure servers that can be shared with people who can follow your glucose levels all the time.
We think it will have a very good impact on our business, particularly in the ped's patients where parents are going to want to follow their children. We've talked to a number of people over the past few months whose child has never been on a sleepover before because they don't dare let them leave the house without being able to watch them. Big uptake in that segment. We think it will help us. It will also help us really with anybody who travels or is away from somebody who's a caregiver. We see a very good use for that product.
We're not looking for huge changes in our revenue model for this. That cradle itself is going to be about a $400 charge starting out of the gate. Our goal with this is to make a system that will greatly enhance our patients' ability to manage their glucose, to take better care of themselves, and, from a business side, sell more sensors.
So that's how the model works for us and that's what we're hoping happens. It won't have the impact as a G4 launch did. I can quantify that. But we think it will help us. We have pretty high expectations here. We need to hit it pretty well. So, we think it will be helpful.
Raj Denhoy - Analyst
And just so I'm clear. That's a feature -- it will work with the current G4. So there's no upgrade needed on that transmitter. You just need to buy the cradle and it all works.
Kevin Sayer - President & COO
Absolutely. You just buy the cradle and go.
Raj Denhoy - Analyst
Okay. And just, lastly, and I know it's in your partner's hands but any updates on timing on the combined products, either the Vibe or the Tandem device?
Steve Pacelli - EVP, Strategy & Corporate Development
No. As we talked about, Raj, a quarter or two ago, we're going start deferring to the partners on timing. These filings are in their hands and so I think we'll let Tandem and Animas speak for themselves.
Raj Denhoy - Analyst
Fair enough. Thank you.

Mimi Pham, ABR Health.
Mimi Pham - Analyst
Hi. Good afternoon. About what percent of the 800 U.S. pediatric endocrinologists you've talked about have prescribed the G4 since launch in February or since approval in February?
Kevin Sayer - President & COO
I couldn't quantify that. We don't have that.
Mimi Pham - Analyst
Would it be fair to say that your goal by year end is to get half of them to have written their first prescriptions or closer to a majority of them? Just based on your comments about the more measured rollout.
Kevin Sayer - President & COO
Mimi, I think we look at this more as a percentage of the patient base as we build our models up rather than just focusing on individual decisions. And we want to see the patient base over time move up to 30% of the overall patient base. We would expect the patient base to move from 10% this year up closer to 20% and then move up, over the next two years, higher than that. We haven't gone so far this year as to break it down by physician and by clinic.
Mimi Pham - Analyst
Okay. And then in terms of the pediatric ramp, I know it's still early but do you get a sense if these are stickier patients just more likely to use CGM 24/7 than periodically?
Kevin Sayer - President & COO
We think particularly the very young patients, care provider, parents are extremely sticky. That's always been a very good patient group for us even when the product was prescribed off label. We know with teenagers it doesn't matter what the device or the therapy or whatever you tell teenagers to do, sticky is kind of a difficult word. But we do well with them and they certainly do well on the system. So, we'll just see how it works over time.
Mimi Pham - Analyst
Thanks. And then, the last question, to follow up, I think, Tom's question on the flash. Can you just give us your thoughts on the additional data presented on Abbott's Flash at the ATTDD meeting back in February? Does it seem like it might keep more folks long-term internationally on just using blood glucose meters?
Steve Pacelli - EVP, Strategy & Corporate Development
Understand the Flash is definitely not CGM. The Flash doesn't provide the patient with real-time information, doesn't provide them a hypoglycemia alerts, etc. So, it's not really a direct comparison to our product offering. I do think there could be an interesting application for Flash. We're watching it.
With respect to the data, I think that the latest data presented by Abbott frankly wasn't quite as good as the first round of data we saw. But we're keeping an eye on it. I think, as we've said in the past, that, if Abbott finds a niche for this product particularly in more of diagnostic marketplace perhaps for non-insulin using type 2's or something like that, it's something that could be great to have Abbott help build the category for once. We've done all the heavy lifting in this category for years and years and years. It would be great to have someone else come in and help build a category that we could come in as a fast follower.
So, we're keeping an eye on it. We haven't, frankly, I don't think anybody has seen much of the product itself yet. So, it's a little bit early to tell. They've stated publicly that they expect to launch in Europe in the second half of this year. They've given no U.S. timeline for a launch or commercialization. So, I think we'll know more maybe by EASD this year in the latter half of the year.
Mimi Pham - Analyst
Great. Thank you very much.

Danielle Antalffy, Leerink Partners.
Danielle Antalffy - Analyst
Thanks so much. Good afternoon, guys, and thanks for taking the question. I was hoping you could comment on utilization trends. So, the last few quarters, we've seen strong utilization trends. I wanted to see if they were persisting and how we think about utilization trends evolving over the next few quarters as, Mimi brought it up, we have pediatrics who you would think, at least in the younger age group, would use the sensor more frequently. SHARE should contribute to utilization. So where can we get to with utilization ultimately as all these products and expanded indications hit?
Steve Pacelli - EVP, Strategy & Corporate Development
You've got to be careful, Danielle, when you talk about utilization trends because, remember, patients are probably wearing it longer than seven days. So, there's a point at which patients, even if all patients are wearing it all the time, you're still not going to have patients wearing four sensors per month.
So, what we've said with G4 PLATINUM, over the course of the last 18 months, has been what we've seen is a combination of more patients wearing it all of the time and a reduction in attrition. But that doesn't necessarily mean that all patients are wearing, for example, three sensors in a month or three-and-a-half sensors per month. So, you've got to really be careful at trying to expect utilization meaning sensors per month to go up in any meaningful fashion.
What we do think is we've moved the buckets of patients where, before a patient might wear it periodically, might wear one sensor a month and take a break; that patient may be wearing two or two-and-a-half or three sensors a month because they're wearing it all the time. But you can't expect utilization in that sense to keep rising because, if a patient's wearing it all the time but extending the life, the utilization is not going to go up.
What we've said is that, and Kevin said it in his remarks, is that attrition trends remain very positive and patients are continuing to utilize sensors. And so (inaudible) on utilization.
Kevin Sayer - President & COO
Yes. The average, as a whole, of sensors used per month per patient has gone up but, like Steve said, we think it's probably because patients are having a better experience overall. We have not seen a reduction in the amount of days people use it across the board. We know people extend the wear.
Danielle Antalffy - Analyst
Okay, great. Thanks so much. And just wanted to ask you guys about, ADA is coming up here I guess next month. Wondering if there's anything coming out at ADA from you guys or from the artificial pancreas side of things that we should be paying attention to.
Kevin Sayer - President & COO
We have about eight poster presentations at ADA. We'll be very busy. And please come and take a look at them. But we'll keep that under wraps until we get there.
With respect to the artificial pancreas, certainly there will be a lot of discussions about that. And, again, it will be programs we're heavily involved with, with groups that are seeing tremendous results and measurements from our CGM to drive the success of those programs. So, yes, there will be a lot. It will be a very busy show for DexCom. You'll hear a lot about us there.
Danielle Antalffy - Analyst
Okay. Thanks so much.

Greg Chodaczek, Sterne Agee.
Greg Chodaczek - Analyst
Hey guys, most of my questions have been answered but just one quick one. Kevin, in terms of operating expense growth excluding non-cash equity, what were those growth rates you were quoting again?
Kevin Sayer - President & COO
We said last year that it would be a 10% to 20% growth on the R&D side, on the cash side, and we said we we'd try and keep SG&A at around 20%. On both cases, and I'll be very candid with you, when you look at opportunities to spend money to find growth for the future.
As you heard about the build-out of the commercial team over the past 12 months, that's a lot more than a 20% increase. We've managed to keep that down in the 20% range because we haven't spent very much on the G&A side. But we'll continue to make investments where we think it's going to grow our business, where it's going to grow our business and where we need to.
That expense growth, we'll stick to that guidance now. We'll take a look at where we are in six months and give you a bit more. But, if you just go back to Q4, the growth from Q4 is very much dialed in to the expansion of the sales force for the full quarter, on those efforts that we undertook.
And on the R&D side, the growth in the R&D expense is very much tied, really, just to the share-based compensation. That was almost 70% of the sequential R&D growth. So, we're looking at that. And we'll probably give you a little more update on that spending once we get six months into the year.
Greg Chodaczek - Analyst
Okay. Thank you for the clarification. And, in terms of pediatrics, your long-term goal is roughly about 30% of your revenues coming from pediatrics?
Kevin Sayer - President & COO
Yes, it is.
Greg Chodaczek - Analyst
Okay. That's all I have. Thanks, guys.
Kevin Sayer - President & COO
Thank you.

(Operator Instructions). Jayson Bedford, Raymond James.
Jayson Bedford - Analyst
Good afternoon and thanks for taking the questions. I don't mean to be repetitive here but just on the sequential jump in SG&A spending, it was a big number. I'm realize the $2.3 million in stock-based comp, the 20 new reps. But, did you increase your marketing efforts there or increase a cost associated with the pediatric launch at all in the first quarter?
Kevin Sayer - President & COO
Certainly, we've got in there. And, again, when you talk to sequential, you'd be talking Q4 to Q1 versus Q1 of last year. If we're going to compare Q1 of last year to Q1 of this year, you need to go back to my remarks.
We had 48 reps in the field at the start of Q1 of 2013. We have almost 90 by the end of Q1 of 2014 and all those were in place early in the year. So, you've almost doubled feet on the street there. We more than doubled the size of our distribution channel management team with respect to payers, distributors, and all the other things associated with getting pharmacy reimbursement over time.
We have built the marketing team up as well, not to the significance we've built up the sales side. Those expenses will probably come more over the course of the year as we do more marketing campaigns and as we run some clinical studies geared towards positioning the product for better reimbursement over time, which won't be part of R&D.
So, as you're comparing to last year, think 48 to almost 90 reps. Think double the number of people on the reimbursement side. That's where that growth comes from on the cash side.
If you go from Q4 of last year to Q1, it's probably 20 new reps and a few people on the other side and the growth isn't near as much. I think the issue with the OpEx, as you compare this year with last year; we're a lot bigger than we were a year ago. We just are. There's no other way to describe it.
Jayson Bedford - Analyst
Right. Okay. Okay, that's helpful, Kevin. I guess the international strength, was it largely due to the entry of new countries or is same country sales growth also tracking above U.S. growth levels?
Kevin Sayer - President & COO
You know, it's both. We do very well and we have some core markets; Germany, Italy, Sweden, the Netherlands. We do extremely well in Europe in those four. And the other markets are growing as well. Those four are kind of the backbone of our European business.
On top of that, we got into Canada in late 2013 and did very, very well in Q1 of 2014 in Canada, both with our standalone CGM and with the Vibe system. So, Canada has really been a very positive launch for us.
Jayson Bedford - Analyst
Okay. And then, lastly for me, just on the pediatric strategy and I may be getting into your sales comp structure here, but is the focus here on a portion of the pediatric endocrinologists out there and to go deep into those physicians or is more of a blanket approach where the goal is to; hey, let's touch them all by year end?
Kevin Sayer - President & COO
Our focus with respect to compensation is to grow the business in total. We reward our team for -- we have, obviously, a model. The biggest reward in our compensation structure is adding new patients to the Company. If our reps are achieving that through pediatric or adult patients, they're compensated the same. We will watch and we will monitor and make those reps that we have out there are going into both areas. If we see somebody not doing adults or not doing ped's, obviously we go check on the territory. But, they're rewarded the same for both.
They have, again, very high numbers to meet, to meet our expectations. So, I can tell these guys are trying to get deep into everywhere they call and also call on a number of clinics. They are measured on both the number of calls that they do, the number of physicians they call on, and also how deep they go. And our term for that is a DexCom Champion. How many champions do you have and how many can you create? And so, all these guys are measured on a number of factors that really meet our overall company and business goals. Our goals are very congruent.
Jayson Bedford - Analyst

William Plovanic - Analyst
Great. Thanks for taking this. Just what was D&A and stock comp in the quarter? And my second question is the depreciation and amortization and stock comp overall for the quarter because there's not a cash flow out?
Jess Roper - VP & CFO
You're going to see that probably in about literally five minutes when we file the Q. But share-based compensation was $8.7 million for the quarter and then we had depreciation and amortization of $1.9 million. All non-cash charges were (inaudible) for the quarter, which includes some accretion, change in far value for some contingent liabilities we have with Sweet Spot, etc.
Kevin Sayer - President & COO
So, the total non-cash expenses are $12.1 million.
William Plovanic - Analyst
Okay. And then, just on the pediatric, you've provided your strategy, kind of what you're doing. You said that you expect this to kind of ramp a little slower. When do you expect the ped's to really gain momentum?
Kevin Sayer - President & COO
I think they're gaining momentum now.
Terry Gregg - CEO
I think we all believe that there's significant momentum. I think Steve characterized it and Kevin as well that, in the adult population, as an example, when we call on an account, they're well-informed, not only about CGM, but particularly about G4 because we've been calling on them for the last several years.
You go into a pediatric account; number one, it's a new account for our sales reps, for the most part, in terms of, if they were co-located with an adult practice then oftentimes we know them but we never called on them. So, there's a relationship management that has to be established as well as the technology understanding. So, it is a bit of going back, as I think Kevin said; not starting over but certainly not the same type of awareness that you have in an adult population.
And all that takes time. It takes repeated visits by the sales force to gain, quite frankly, the trust of that physician population, which we, in some cases, it's a first-time visit. I mean when we've been out in the field lately, from a management standpoint, calling on pediatric clinics, it's amazing. In fact, because I've been doing this for so long, the most startling thing to me is that it's like; holy cow, they don't understand this. We have got to be sure that they understand the basics of CGM at that level in order for them to be successful. So it is literally a step back in time but we do expect that to ramp up very quickly.
Steve Pacelli - EVP, Strategy & Corporate Development
Yes, I think the cautionary to the extent you read any cautionary language into our prepared remarks, it's really just making sure that the street doesn't get ahead of itself in thinking it was just going to be a flip-the-switch launch and kind of within a month or two we were going to have 30% or 40% penetration into the ped's market. That's all.
Kevin Sayer - President & COO
That's it.
Steve Pacelli - EVP, Strategy & Corporate Development
It's ramping, ramping just fine.
William Plovanic - Analyst
Perfect. That's all I had. Thank you very much.

We have no further questions at this time. I will now turn the call back to Terry Gregg for final remarks.
Terry Gregg - CEO
Thank you. And thanks for joining us today. You know, I'm awfully proud of what we have accomplished. You noticed during the course of the conversation we said nothing about inclement weather having an impact on us. We blew through that, obviously, and overcame that even when officers were closed and still had a quarter to stand by and I'm very proud of the Company.
And I would say this; again, for DexCom, we say what we're going to do and then we go out execute it. And that's the best thing that I can say about a company performing at this level. So, with that, I'll close. Thank you.
