Ladies and gentlemen, thank you for standing by.
Welcome to the BSX Q2 2015 earnings conference call.
(Operator Instructions)
As a reminder this conference is being recorded.
I would now like to turn the conference over to our host, Ms. Susan Lisa.
Please go ahead.
Susan Lisa - VP of IR
Thank you, Katie.
Good morning, everyone, and thanks for joining us.
With me on today's call are Mike Mahoney President and Chief Executive Officer, and Dan Brennan, Executive Vice President and Chief Financial Officer.
We issued a press release earlier this morning announcing our Q2 2015 results, which included reconciliations of the non-GAAP measures used in the release.
We have posted a copy of that release as well as reconciliations of the non-GAAP measures used in today's call to the investor relations section of our website under the heading Financial Information.
The duration of this morning's call will be approximately one hour.
Mike will begin our prepared remarks with an update on our business progress and his perspectives on the quarter.
Dan will then review our overall Q2 2015 financial results as well as guidance for full-year 2015 and Q3 of 2015.
During today's Q&A session Mike and Dan will be joined by our Chief Medical Officers Dr. Keith Dawkins and Dr. Ken Stein.
Before we begin I'd like to remind everyone that this call contains forward-looking statements within the meaning of federal securities laws which may be identified by words like anticipate, expect, believe, estimate and other similar words.
They include, among other things, statements about our growth and market share, new product approvals and launches; clinical trials; cost savings and growth opportunities; our cash flow and expected use; our financial performance including sales, margins, earnings, and other Q3 employer 2015 guidance; as well as our tax rates, R&D spend and other expenses.
Actual results may differ materially from those discussed in the forward-looking statements.
Factors that may cause these differences include those described in the risk factors section of our most recent 10-K and subsequent 10-Qs and 8-Ks filed with the SEC.
These statements speak only as of today's date and we disclaim any intention or obligation to update them.
At this point I'll turn it over to Mike for his comments.
Mike?
Mike Mahoney - President & CEO
Thank you, Susie.
Good morning, everyone.
In Q2 Boston Scientific posted another strong result as we continue to execute on our long-term commitments.
We delivered worldwide operational revenue growth of 6%, 10% adjusted operating income growth, and 12% adjusted EPS growth, excluding a $0.02 negative impact from foreign exchange.
These results reflect the high-performance of our global teams, our differentiated portfolio and the diversification of our business.
As detailed in our May investor day meeting, our Company remains focused on high performance.
We aim to drive mid single-digit operational revenue growth and consistent operating margin expansion, which in turn will drive double-digit adjusted EPS growth excluding the impact of foreign exchange.
Dan will detail our commitment to this goal with full-year 2015 adjusted EPS guidance of $0.88 to $0.92, which is unchanged from our original guidance in February.
Importantly, we've maintained our EPS guidance despite a $0.06 to $0.07 impact from FX versus our original expectation of a $0.04 negative impact.
We remain focused on overcoming these FX challenges to deliver against our original adjusted EPS guidance range.
Now I'll provide some highlights on Q2.
Dan will review the financials and Q3 guidance and then we'll take your questions.
Please note that in my remarks all references to growth are on a year-over-year constant currency basis unless otherwise specified.
Now for a few highlights for the quarter.
We delivered broad-based global revenue of 6%, on target with our goal for consistent revenue growth, as we've now grown revenue 6% or better for four consecutive quarters.
This solid, balanced growth is driven by robust execution in our core businesses, strong new product launches, increased traction from our structural heart business, continued international expansion, and leverage from our acquisitions.
Our MedSurg segment is building momentum and each business accelerated year-over-year revenue growth in Q2 compared to Q1.
Endoscopy's year-over-year growth rate improved from 4% in Q1 to 6% in Q2 and this growth is fueled by our new SpyGlass digital launch, and our expanded capabilities in endoscopic ultrasound, which is a fast and emerging growing field of minimally invasive procedures.
Neuromodulation revenue accelerated in Q2, growing 9%.
This growth was led by continued adoption of our US market-leading precision Spectra spinal cord stimulation platform, which offers differentiated capability via our Ilumina 3-D neural targeting and CoverEdge 32 contact paddle.
Importantly, we're now entering the primary cell non-rechargeable market in Europe with the launch of Precision Novi.
With the Novi technology, we have leveraged the unique and flexible capabilities of the Spectra platform.
We're really excited about its potential to take share in this sizable market as incremental to BSC.
Turning to urology and women's health, we also improved its top line, growing 7% in second quarter after 3% growth in first quarter.
The acceleration was driven by a comprehensive portfolio in our ongoing international expansion efforts.
We are excited about the pending Q3 closing of the AMS male urology acquisition as we are confident that this deal will further strengthen our category-leading global urology franchise.
Switching gears, our cardiovascular group grew 10% in second quarter, with interventional cardiology outpacing our market growth estimate with a 7% increase in sales.
Growth was well balanced across our IC franchises and geographic regions.
In DES, the SYNERGY stent now represents approximately 30% of our European DES sales and it remains on track for year-end 2015 US approval.
And SYNERGY, with its unique bioabsorbable polymer coating and thin struts, is designed from the ground up to promote healing.
We're excited to bring this premium and differentiated workhorse stent to the US and Japanese markets.
Also, as evidence of our commitment to offering the broadest IC portfolio, we announced earlier in the week that we've initiated the FAST study of our first fully resorbable drug-eluting scaffold system.
FAST is a true second-generation of fully resorbable scaffold that seeks to address the limitations of the current commercially available devices.
We expect to enter CE mark countries with a second generation FRS device in 2017.
Our PCI guidance business also continued to deliver strong results.
And we recently submitted our 510(k) for US clearance of our integrated fractional flow reserve imaging system.
We look forward to a limited market release in both the US and Europe in Q4 this year.
And, finally, the IC performance was fueled by our strengthening structural heart business, which includes our Lotus percutaneous aortic valve and a WATCHMAN left atrial appendage closure device.
We believe that we're uniquely positioned for the long term to assist hospitals and physicians with the growing structural heart demand due to the unique capabilities of both WATCHMAN and Lotus.
Lotus continues to penetrate the European market and we're executing on the pipeline that we detailed at investor day.
Our clinical evidence continues to build and we remain on track to complete enrollment in both our REPRISE III IDE and RESPOND post-approval study by year-end 2015.
The first 100 days of the US WATCHMAN launch have been very successful and we expect to complete rollout of the first 100 accounts by year end.
We're very pleased with the implant success rate and the high quality of patient outcomes thus far, which reflect our controlled rollout and proven training program.
We have a great deal of clinical evidence demonstrating that WATCHMAN can uniquely benefit a large global patient population.
And in terms of US reimbursement, we will understand more about the national coverage decision as well as the new technology add-on payment in the back half of 2015.
So, overall, we're very excited about our progress in structural heart and expect to deliver full-year 2015 structural heart revenue at the high end of the $75 million to $100 million goal that we provided at our May 1 investor day.
In peripheral interventions, the core business continues to execute and the integration of the legacy Bayer business is going extremely well.
Bayer grew at a double-digit rate in Q2 and we're seeing strong commercial and operational synergies with our peripheral business.
We're also encouraged with the early results of our commercial partnership with CR Bard in their Lutonix drug-coated balloon technology.
Now I'll provide comments on CRM.
On our first-quarter earnings call we projected a slowdown in our worldwide CRM sales for the balance of 2015 due to difficult comparisons, replacement headwinds and competitive launches, particularly in the US.
Q2 global CRM sales did, in fact, slow to a 1% decline, and we continue to anticipate some softness in US CRM sales through year-end 2015.
But it's very important to highlight that our better European CRM business delivered mid-single-digit growth for the fifth consecutive quarter.
In Europe we are estimating we are taking share with a differentiated portfolio, including full CRT-D and CRT-P quad systems, ACCOLADE 3T MRI safe pacemakers and our second-generation S-ICD EMBLEM.
In addition, our industry-leading EnduraLife life battery technology continues to differentiate Boston Scientific and set us apart with the multiple new independent and contemporary longevity data sets that were recently presented at HRS.
We believe device longevity plays an important role in reducing costly complications associated with replacement procedures and reduces overall healthcare costs.
These European CRM results are encouraging and relevant, as we expect to launch the full quad in the US in early 2016.
And we are transitioning to a full launch of EMBLEM S-ICD in the US in Q3.
Additionally, we expect to have Brady MRI in the US by year-end 2015.
So the products driving above market growth in Europe are expected to be available soon in the US as well as Japan.
In EP, we are beginning to build momentum with 9% growth in second quarter, led by our differentiated mapping and navigation system.
Rhythmia is now accelerating the pace of its global rollout and physicians praise its speed, clarity and density of imaging.
We're also encouraged by key upcoming launches in EP such as our navigation-enabled [intellanav] open irrigated ablation catheter in Europe, slated for Q3 2015.
So, stepping back to look across all the businesses, our 6% operational revenue growth reflects the strong diversification of our portfolio, our focus on innovation, and our ongoing globalization efforts.
In Q2, US Europe and Asia regions all grew 6% and the emerging markets grew 12% led by 21% revenue growth in China.
Importantly, we believe that we are well-positioned to sustain our global performance with several key new product launches that are early in their rollout.
To highlight a few, in Q2 our WATCHMAN left atrial appendage closure device launched in the US.
SpyGlass digital began is rollout.
Our next generation EMBLEM S-ICD launched in Europe.
And our primary cell spinal cord stimulation system, Novi, launched in Europe.
All these launches are off to good starts due to the unmet needs they address for patients and their clinical differentiation in the marketplace.
And, finally, we continue to execute on our margin expansion goals on the back of strong adjusted operating margin expansion of 230 basis points versus Q2 2014.
We have high visibility in achieving our 25% adjusted operating margin goal in 2017 and continued improvement beyond 2017.
Overall, we are executing well globally and delivering on our strategic plan and commitments.
We continue to believe that Boston Scientific is uniquely positioned to deliver consistent mid-single-digit growth and double-digit adjusted EPS growth, excluding FX, given our strong pipeline, global expansion opportunities and significant opportunities for margin improvement.
I'd like to thank our employees for their tremendous winning spirit and their commitment to the Company.
Now let me turn the call over to Dan for a detailed review of our financials.
Dan Brennan - EVP & CFO
Thanks, Dan.
I'll start with some overall perspective on the quarter before getting into the details.
We generated adjusted EPS of $0.22, achieving the high end of our guidance range of $0.20 to $0.22, and representing 2% year-over-year growth.
Excluding the $0.02 unfavorable foreign exchange impact, Q2 adjusted EPS grew 12% year over year.
The strong performance in Q2 was driven primarily by operational revenue growth and gross margin expansion.
Our Q2 2015 adjusted operating margin of 22.1% exceeded the high end of our Q2 adjusted operating margin guidance range of 21% to 22%, and represents improvement of 230 basis points over Q2 of 2014.
This is the second consecutive quarter where total Company adjusted operating margin expanded by at least 200 basis points over the prior-year quarter.
And despite significant FX headwinds, our goal for the full-year 2015 remains double-digit adjusted EPS growth.
Now I'll provide a detailed review of our Q2 business performance and operating results.
Unless stated otherwise, references to quarterly results increasing or decreasing are in comparison to the second quarter of 2014, and all revenue growth rates are given on a year-over-year constant currency basis.
For the second quarter of 2015 consolidated revenue of $1.843 billion represented operational revenue growth of 6%, which excludes the impact of foreign exchange and the divested neurovascular business.
On an as reported basis, revenue declined 2% year over year.
Excluding an approximate 170 basis point contribution from the Bayer Interventional acquisition, organic revenue growth was 4% in the quarter.
The foreign exchange impact on sales was a $141 million headwind compared to the prior year, and it was only $1 million worse than we assumed in our Q2 guidance range.
I will now provide more details on the revenue results for our seven businesses which roll up into the three reporting segments.
I'll start with MedSurg where the total group sales of $583 million grew 7% and adjusted operative margin was 30.4%.
This represents an increase of 20 basis points over Q2 of 2014 and 140 basis points sequentially.
Endoscopy sales were 6% worldwide driven by double-digit growth in Biliary, the largest franchise fueled by SpyGlass DS and the AXIOS stent system from our recent acquisition of Xlumena.
Latin America continued to stand out with growth north of 30%.
Urology and women's health posted solid worldwide sales growth of 7%, driven by strong urology performance in the US and Europe.
Pelvic floor revenue grew low single digits globally against a market that we believe is down slightly.
Emerging markets revenue growth was impressive in the quarter, up almost 40%.
To close out the MedSurg results, our worldwide neuromodulation business posted solid sales growth of 9% and we're encouraged by the early launch of our Precision Novi primary cell device in Europe, which gives us our first entry into a $200 million-plus OUS non-rechargeable market.
Turning now to the cardiovascular group which consists of the interventional cardiology and peripheral intervention division, global sales for the group totaled $743 million and grew 10%.
Cardiovascular group adjusted operating margin for the quarter of 30.5% represented a 440 basis point improvement year over year on strong stent volumes and US WATCHMAN revenue contribution.
We expect cardiovascular segment adjusted operating margin expansion to moderate in the second half of the year, primarily due to the timing of clinical spend.
Worldwide interventional cardiology sales of $515 million grew 7%.
Growth in IC was strong across all regions, with the US up 8%, Europe up 5%, and Asia up 11%.
DES sales grew low single digits globally, with Asia's DES revenue growing double digits for the second straight quarter.
This was driven by the continued strength of the Promus PREMIER stent in Japan and strong uptake of Promus PREMIER in China.
Worldwide complex PCI solutions also grew low single digits, led by solid performance in imaging, particularly in Japan.
Our structural heart franchise was the largest contributor to worldwide IC revenue growth in the quarter.
And as Mike mentioned, we're comfortable with the high end of our $75 million to $100 million revenue goal for the full-year 2015.
The strong growth in IC is a strong combination of the complex PCI and DES businesses growing slightly above market and strong contributions from WATCHMAN and Lotus.
The comps in our IC business become much more challenging in the second half of this year.
We remain focused on driving above market growth by providing the interventional cardiologists with the broadest portfolio of technology and differentiated product to treat the most complex coronary cases.
Peripheral interventions delivered worldwide revenue growth of 16%, driven by strong double-digit growth in the acquired Bayer business and 4% growth in the legacy Boston Scientific PI business.
The distribution deal with CR Bard for their Lutonix drug-coated balloon drove pull-through of our broader PI portfolio.
And interventional oncology grew mid single digits on the performance of new product launches and a focus on the interventional radiologist globally.
Turning now to our rhythm management group, which includes our electrophysiology and cardiac rhythm management divisions.
Worldwide rhythm management sales in Q2 of $517 million were flat to Q2 of 2014.
Rhythm management adjusted operating margin in Q2 of 14.1% represents a 190 basis point improvement year over year, the sixth consecutive quarter of rhythm management's adjusted operating margin improvement of 100 basis points or more versus the prior year.
As a reminder, we expect rhythm management's adjusted operating margin expansion to accelerate in the second half of the year given the launch timing and favorable gross margin profiles of the EMBLEM S-ICD and ACCOLADE product lines.
We believe that we can drive at least 200 basis points of improvement in the second half of 2015 versus the first-half rate of 14.1%, marking significant progress towards our goal of achieving a rhythm management adjusted operating margin north of 20% by 2017.
Worldwide electrophysiology revenue was up 9%, with high single-digit growth in both the US and Europe.
And we are encouraged by our first-half performance in EP and the capabilities we are building globally.
For the cardiac rhythm management division, Q2 worldwide sales decreased 1%, consistent with expectations given replacement headwinds, difficult comparisons and competitive launches.
On a worldwide basis, defib sales of $335 million grew 1%.
US defib revenue declined slightly on replacement headwinds and continued market penetration of CRTD quad systems.
As Mike mentioned, we're excited to transition to the full US launch of EMBLEM in Q3 and launch our own quad system in the first half of 2015.
Worldwide pacer sales totaled $125 million and declined 4%.
The decline was primarily US driven as we experienced share loss to competitors with MRI-safe capabilities.
We expect have our MRI compatible pacemaker approved in the US in Q4 of this year.
As we communicated last quarter, we expect global CRM year-over-year revenue growth to be relatively flat in the second half of this year.
Despite this flat revenue outlook we expect to deliver significant year-over-year adjusted operating margin expansion in rhythm management.
Turning now to the P&L, adjusted gross profit margin for the second quarter was 71.3%, up 100 basis points year over year.
Gains from our value improvement programs and our FX hedging program positively impacted gross margins by 150 basis points and 100 basis points, respectively.
And this was offset partially by 150 basis points of negative price and mix.
Adjusted SG&A expenditures were $688 million or 37.3% of sales in the quarter.
Our Q2 2015 adjusted SG&A rate was down 90 basis points from Q2 of last year.
And we continue to believe our full-year 2015 adjusted SG&A rate will be in the range of 36.5% to 37.5%.
Adjusted research and development expenses were $200 million in the second quarter or 10.9% of sales.
This adjusted R&D rate is roughly flat both sequentially and year over year.
We still believe our full-year adjusted R&D rate will be in the range of 11 % to 12% of revenue and our expecting a sequential uptick in R&D spending as a percent of revenue, particularly in the cardiovascular segment.
Royalty expense was $18 million in the quarter, or 1% of sales, consistent with our guidance.
On an adjusted basis pretax operating income was $408 million in the quarter, or 22.1% of sales, up 230 basis points year over year, and exceeding our Q2 adjusted operating margin guidance of 21% to 22%.
Adjusted pretax operating income grew 10% driven by a 28% increase in our cardiovascular segment.
GAAP operating income, which includes GAAP to adjusted items of $189 million, was $219 million in Q2 2015.
The primary GAAP to adjusted items for the quarter included restructuring related charges of $16 million, contingent consideration expense of $19 million, and amortization expense of $116 million.
As of June 30, our total legal reserve was $1.117 billion.
Now I'll move on to other income and expense.
During the quarter, we completed an offering of $1.850 billion of senior notes, with an average interest rate of 3.4%; arranged a new bank term loan of $750 million; and refinanced a $2 billion revolving credit facility with a new $2 billion revolving facility maturing in 2020.
We used a portion of the net proceeds from the notes offering to redeem $1 billion of outstanding notes due in 2015 and 2016, with an average interest rate of 6.3%.
The remaining net proceeds of the notes offering, together with the borrowings under the $750 million term loan, are expected to fund the purchase price for the AMS male urology portfolio.
Interest expense for the quarter was $106 million, which includes a pretax charge of approximately $45 million associated with the senior note refinancing.
Excluding this charge, our interest expense for the quarter was $61 million compared to $54 million in Q2 of last year.
And the increase was primarily due to a one-month period during which we incurred interest on the $1.85 billion of newly-issued notes as well as the $1 billion of outstanding notes due in 2015 and 2016, prior to their redemption.
Our next bond maturity of $250 million is not due until January 2017.
Other expense was $8 million, and this consisted primarily of foreign exchange losses incurred during the quarter.
Our tax rate for the quarter, was 2.9% on a reported basis and 13% on an adjusted basis.
Our Q2 adjusted tax rate includes slightly more than $1 million of unfavorable discrete tax items.
And we continue to expect our full-year 2015 adjusted tax rates to be in the range of 13% to 15%.
Finally, as mentioned, Q2 2015 adjusted EPS of $0.22 includes $0.02 of unfavorable FX, and represents 2% year-over-year growth or 12% growth excluding the impact of foreign exchange.
On a reported GAAP basis, Q2 2015 EPS was $0.08 and includes net charges and amortization expense totaling $192 million after-tax.
GAAP EPS of $0.08 compares to break even on a GAAP basis in the prior-year period.
Moving on to the balance sheet, DSO of 59 days decreased 4 days compared to June of 2014 due primarily to strong collections in Europe.
Days inventory on hand of 163 days was up 10 days compared to June of last year and up 7 days compared to December 2014 due to higher inventory in advance of launches and lower cost of goods sold, driven primarily by standard cost improvements and favorable product mix.
Adjusted free cash flow for the quarter was $406 million compared to $262 million in Q2 of last year.
This increase was primarily due to higher adjusted operating profit, lower capital expenditures, and a continued focus on working capital management.
We continue to expect our full-year 2015 adjusted free cash flow to be approximately $1.3 billion.
Capital expenditures were $46 million in Q2 of this year compared to $64 million in Q2 of last year.
The decrease is attributable to timing and we still expect CapEx to be roughly $260 million for the full-year 2015.
There were no share repurchases in the quarter, consistent with our decision to temporarily suspend the share repurchase program following the announcement of the agreement to acquire AMS men's health and prostate health businesses.
Near term, our capital allocation priorities are debt repayment, maintaining flexibility and tuck in M&A.
Beyond the 12 to 18 months suspension period, any continuation of our share repurchase program would be subject to business development opportunities, market conditions, our stock performance, regulatory trading windows, and other factors consistent with prior guidance.
And we expect to end 2015 with between 1.36 billion shares and 1.37 billion fully diluted weighted average shares outstanding.
And since we plan to keep the buyback suspended for some or all of 2016 we expect the 2015 trend in fully diluted weighted average shares to continue into 2016.
I'd like to conclude with guidance for Q3 and full-year 2015.
As a reminder, AMS is excluded from our guidance as the transaction has not yet closed.
For Q3 2015 we expect consolidated revenue to be in a range of $1.79 billion to $1.84 billion.
If current foreign exchange rates hold constant, we estimate the headwinds from FX should be approximately $125 million or 680 basis points relative to Q3 of 2014.
On an operational basis we expect consolidated Q3 sales to grow year over year in a range of plus 4% to plus 6%.
We expect adjusted gross margin for the third quarter to be in a range of 71.5% to 72.5%, reflecting the favorable gross margin profile of new product launches.
Assuming a more normalized adjusted R&D rate in Q3 of 11% to 12%, we expect adjusted operate margin in the third quarter to be approximately 22.5% plus or minus 25 basis points.
Finally, adjusted EPS is expected to be in a range of $0.21 to $0.23 per share and reported GAAP EPS is expected to be in a range of $0.10 to $0.13 per share.
For the full year 2015, we now expect consolidated revenue to be in the range of $7.275 billion to $7.375 billion, which represents a year-over-year growth of 4% to 6% operationally.
If current foreign exchange rates hold constant, we expect the FX headwinds to be roughly $460 million for the full-year 2015.
Based on our strong first half and expectations for the second half of the year, we now expect our full-year 2015 adjusted operating margin to be approximately 22.5% plus or minus 25 basis points.
This represents an improvement of roughly 230 basis points over the full-year 2014.
And as a reminder, our initial full-year 2015 adjusted operating margin guidance contained a mid point of 22% which we raised to 22.25% on our Q1 earnings call, and our current guidance of 22.5% represents the second consecutive quarter where we will have raised the mid point of our full-year adjusted operating margin by 25 basis points.
Finally, we are reiterating our full-year adjusted EPS guidance range of $0.88 to $0.92.
Recall, this range includes a $0.06 to $0.07 impact from unfavorable FX.
We're proud that our team is focused on overcoming these FX headwinds to deliver against our original guidance range.
The high end of our adjusted EPS guidance range represents double-digit growth, and based on current rates approximately 15% growth at the mid point when you exclude the impact of foreign exchange.
On a GAAP basis we expect EPS to be in a range of $0.28 to $0.34.
I encourage you to check our investor relations website for Q2 2015 financial and operational highlights, which outlines Q2 results as well as Q3 and full-year 2015 guidance, including P&L line item guidance.
And with that, I'll turn it back to Susie who will moderate the Q&A.
Susan Lisa - VP of IR
Thanks, Dan.
Katie, let's open it up for questions for the next 25 minutes or so.
In order to enable us to take as many questions as possible please limit yourself to one question and one related follow-up.
Katie, please go ahead.

Mike Weinstein, JPMorgan.
Mike Weinstein - Analyst
Thank you and good morning.
Two items, and I'll start maybe with structural heart.
You had talked at the analyst meeting about Lotus market share trending north of 10% in Europe.
Could you just spend a minute on that?
I think there was some back and forth at the meeting.
Just trying to get a sense of where Lotus is at this point, so anything more you can give us there.
And are there any metrics you can share on the WATCHMAN launch at this point in the US?
And how should we think about the dependence upon reimbursement, either the NCD or the add-on payment, in order to drive growth in 2016 and beyond?
Thanks.
Mike Mahoney - President & CEO
Sure, thanks for the question.
Overall, as you mentioned, in the script there we are very pleased with our performance overall.
We took the guidance up to the high end of the range of $75 million to $100 million, which includes, as you indicated, WATCHMAN and Lotus.
I do think having the combination of Lotus and WATCHMAN does uniquely position us in a competitive structural heart field, particularly given the lead that we have in the US for the WATCHMAN platform globally.
Starting with WATCHMAN, your first question, the great news is we're on track and actually slightly ahead of schedule in terms of our year-end goal of driving 100 large account openings in the US.
So, we're actually ahead of pace there, which is very encouraging.
We indicated during the script we're very pleased with the clinical results we're receiving.
And a lot of that's due to the very measured and, we believe, thorough training program that we put in place.
The implants to date are being split pretty equally across interventional cardiologists and electrophysiologists, which supports our commercial model.
And in terms of the reimbursement, nothing really new to report there.
We're going to learn a lot more in the second half of 2015, starting with the NCD.
We should learn more about the NCD in November with the final decision in first quarter of 2016.
That public comment was closed in June and we had over 80 supportive comments and very nice support from HRS, ACC and SCAI.
So, really happy about our launch of WATCHMAN.
Turning to Lotus, we continue to be on track with the pipeline that we laid out at the investor day meeting in terms of the additional valve sizes and the 14 French catheter, as well.
And in terms of the share -- similar to the feedback that we had at investor day.
We have about a 90% reorder rate with our existing customers in TAVR, which is great, given the number of competitors in Europe.
Once customers use Lotus, 90% of the time they continue to reorder consistently.
And we have about what we estimate to be one-third of the market share in the accounts that we're currently penetrated in Europe.
So, we'll continue to expand new accounts as we continue to expand our training programs, and we made very good progress, we believe, in the second quarter.
Susan Lisa - VP of IR
Keith, do you want to add anything?
Keith Dawkins - Chief Medical Officer
Just to say, Mike, that on the clinical side, the London Valves meeting in Berlin (inaudible) in September will have the important data set, including the 250 patient REPRISE II extension one-year data, and the first 500 patients -- that's half the patients -- with the RESPOND post-market study, and then more important amounts of data coming out of TCTin October.
Mike Weinstein - Analyst
Thanks, Keith.
Mike, what's the appetite as well as the balance sheet bandwidth for additional M&A post the AMS acquisition?
Mike Mahoney - President & CEO
As you know, we've always been, we think, pretty smart with our acquisitions.
So, over the last few years with the Bayer acquisition, ET alliance, and now the AMS that we've moved into faster markets.
In terms of the capacity, we still have, as Dan indicated in his script, we have capacity for tuck-in M&A which is what we've historically done since I've been here.
So, I think you'll see us continue to be active in the talk in M&A area so long as it hits our strategic fit and financial guidelines that we lay out.
Mike Weinstein - Analyst
Okay, thanks, Michael.
I'll let some others jump in.
Operator
Rick Wise, Stifel.
Rick Wise - Analyst
The US CRM business, you both said I think you expected some additional headwinds from a product competitive point of view.
I'm just curious -- it was a little worse than I expected, the pressure was a little greater -- was it better or worse than you expected?
And just as part of that, obviously you're doing great in Europe with the mid-single-digit growth with the full next wave portfolio.
Is that the way we should think about the growth we could see in the United States once you have that in 2016 and beyond?
Mike Mahoney - President & CEO
The answer to your question is yes.
And that's really why we articulated that.
We grew over 5% in Europe with that new cadence of product.
And it's been consistent, five quarters in a row of performance like that, despite the tough comps in Europe.
We have a very strong portfolio and that's the portfolio that we will be launching essentially in 2016 in the US and then later in Japan.
Overall, the US has some pressure, we called it, last quarter.
We'll continue to see some softness there.
So, we anticipate maybe flattish growth in the second half for worldwide CRM.
But we really build a lot of momentum going into 2016 with that portfolio and the launch of EMBLEM in the US in the back half, as well.
I think the other good news is, for CRM overall, if you look at the trailing 12 months, we're up 2% to 3%.
I think if you look at the longer-term perspective, we're up 2 to 3 points.
And given the strength in Europe and as we position the portfolio in the US for 2016 we're positive about, we're very enthusiastic about driving above market growth over that time period.
Rick Wise - Analyst
Okay.
And just turning to operating margins, Dan, if I'm reading it right, obviously you had terrific year-over-year expansion.
It looked great.
On a sequential basis, everything stepped down a little bit from the first quarter.
Is that currency?
Is that something about the OpEx that we should be sensitive to?
Obviously you're reiterating your confidence about the year in the second half.
Dan Brennan - EVP & CFO
Yes, Rick, it really is more about the OpEx.
And we had talked about that on the Q1 call, that Q2 is historically and should prove again this year to be the highest OpEx quarter of the year, primarily driven by the significant amount of tradeshow activity in all the divisions.
Think PCR and DDW and AUA and all the different HRS all happen in the second quarter.
So, that's really the key driver.
And recall our range was 21% to 22%.
So, we called that that was going to be down from Q1 and we were able to deliver 22.1%.
Rick Wise - Analyst
Thank you so much.

Just a couple quick questions and I want to focus mine again on WATCHMAN.
First, Mike, I was just wondering if you could talk a little bit about the demand side of the equation.
I realize fully that this is a controlled rollout and you need to be careful about training.
But in the centers where you are rolled out what are you seeing from the demand side, either for physicians and patients?
Anything that surprised you in the early going?
Again, I'm particularly interested in just the demand for the product in the center that you're launched.
Mike Mahoney - President & CEO
We have Dr. Stein here.
I thought maybe he could provide some commentary on your question and I could add on to it.
Ken Stein - Chief Medical Officer
Yes, Bob, we've been really gratified at the demand where we've launched it.
We've been really carefully controlling the number of sites as we bring them on.
As Mike mentioned in his script, we're actually bringing them on a bit faster than we had thought we would when we spoke at the investors day.
But that really is what's throttling the use of the device at this point.
We have folks really asking us, joining, we're filling all of our training programs.
It's early to say who are the patients who are getting it, but what we've seen to date, both in terms of patient election and in terms of patient outcomes, is really right in line with what we expected to see based on our prior clinical trials.
Bob Hopkins - Analyst
And then the other thing I wanted to ask about as it relates to WATCHMAN is just a little bit more specific on the reimbursement side relating to the add-on payment.
I was wondering if you could set some expectations for us.
How confident are you that you will get that add-on payment?
And if you don't get it, does that change the way you think about the rollout of the product and the demand for the product in 2016?
Mike Mahoney - President & CEO
I think we really won't provide any additional comments, giving a percentage on that.
We're very confident in the data of WATCHMAN, as Dr. Stein has articulated.
We're very pleased with the clinical outcomes that we've seen in the launch.
So, we think the submission has unprecedented clinical data to support it.
We won't provide any further comments in terms of putting odds against it.
And hopefully at the end of the 3Q earnings call we'll have better visibility to it.
Bob Hopkins - Analyst
Yes, but if you don't get it does that matter to demand?
Will it move away from -- how confident are that you will get it -- but if you don't does that have a big impact, do you think, on the rollout of the product?
Mike Mahoney - President & CEO
We're having a lot of success right now.
We will open 100 centers this year.
So, there is a strong demand for it.
If it delivers an unmet patient need for patients who suffer from atrial fibrillation or risk of stroke.
Ken, if you have any additional thoughts on it?
Ken Stein - Chief Medical Officer
The only other thing that I just want to draw attention to is, in addition to the NTAP, CMS has also proposed reassigning into a new, higher class DRG.
So, as opposed to the DRG 251, they proposed reassignment to 273-274, which would represent a 20%, we anticipate, reimbursement to hospitals.
And we'd expect hearing about that roughly in the same time frame as the NTAP.
Bob Hopkins - Analyst
Great.
Thanks very much.
Operator
David Lewis, Morgan Stanley.
David Lewis - Analyst
Just two quick questions.
First, Mike, in thinking about synergy and that number you gave us of 30% mix ex US, that obviously suggests to a lot of us that conversion has been a lot tougher for SYNERGY and there's obviously been more sensitivity to price and value.
So, two questions off of that.
How would you expect US mix to track relative to the ex-US experience?
And then, just generally, your comments on FAST, the question I had is, is FAST worth it?
Can you actually demonstrate better outcomes with FAST and SYNERGY?
Is that investment for shareholders a good investment in your view?
Mike Mahoney - President & CEO
Starting with SYNERGY, I think the big difference in the US and Europe -- really, a difference in Europe as well as Japan, as well -- is high variance, much higher variance of pricing country to country.
So, we've been very thoughtful about which countries we launch SYNERGY in and which countries we don't.
As you said, it represents 30% of our overall Europe DES revenue mix, but it represents greater than 50% of our share, approximately, the 10 EU countries that we're selling it in.
Where we sell it, we drive over 50% share, and those accounts are paying a premium.
And there are many countries where we don't sell it at all.
In the US, there's less variance in the pricing across the hospital system.
As a result of that, we do expect the share to be quite significant in terms of the mix of SYNERGY.
We do believe it deserves a premium but it'll be a premium that won't inhibit its adoption.
We do believe this will be a share taker and will represent a significant percentage of the mix in the US once we launch it.
On fully resorbable, we're committed to innovation and we'll only bring this to the market in Europe and in the US if it delivers an unmet clinical need.
So we don't believe the existing generation products are able to deliver in a workhorse environment.
And we're only going to invest in FRS through the CE mark and/or the FDA if we're confident that it delivers on the commitments and promise that we want it to.
Because we believe with SYNERGY we have a best-in-class differentiated platform with a very large lead in the US.
So, we're going to really maximize that and we're going to be very smart about our FRS commitments.
David Lewis - Analyst
Okay, that's very helpful, Mike.
And then, Dan, on CRM, obviously they've been flat or stable the last three quarters.
I know you mentioned EMBLEM will give you a boost here in the back half of 2015.
So, you pick up 200 basis points on EMBLEM, that gets you to 16, 17, depending on how you cut the math.
How do you get the next 200 to 300 basis points over the next 18 or so months?
Dan Brennan - EVP & CFO
I think one thing that you see, first of all, from the first half of this year is that EP is growing.
And that's been a big part.
CRM gets a lot of the focus but think rhythm management, that also includes EP, and EP grew 6%, grew 9%.
So, that's a piece of it.
And then the other part -- and I think you correctly call it out -- is we have significant gross margin enhancing products coming out on the CRM front.
So, if you think EMBLEM, you think ACCOLADE, and you think our quad system in the first half of next year in the USA, those are all accretive to CRM gross margin.
The benefits of that are all seen in the overall rhythm management.
And the last piece, I would say, is, as we talked about our plant network optimization, the work on the most recent one, which is the benefit of moving a lot of the electrophysiology products from Northern California to our plant in Costa Rica, the work on that finishes at the end of this year and we'll start to accrue the benefits of that in 2016 and beyond.
So, all those, in addition to the many other specific programs in SG&A and R&D to drive efficiencies has us confident that we will hit that north of 20% number by 2017.
Susan Lisa - VP of IR
Just on Synergy and FAST, Keith do you want to comment anything?
Keith Dawkins - Chief Medical Officer
Sure.
David, just a couple of things.
In relation to the mix of SYNERGY in Europe, of course we don't have reimbursements in France yet, which we're anticipating in Q4.
And France is the largest DES market in Europe so that will make a significant difference.
And then with regard to FAST, I think we all agree that the currently available commercial FRS product is not a workhorse product with low-single digit market share four years after CE mark.
So, we think and we're confident that we can improve on the acute performance of FRS with our differentiated technology.
And that's the purpose of this first human use study, to study the performance of those (inaudible) products.
And we'll give more details of that at TCT this year.
David Lewis - Analyst
Great.
Thank you very much.
Operator
Josh Jennings, Cowen and Company.
Josh Jennings - Analyst
I was just hoping for an update on the subcutaneous ICD platform, if there's anything new to report on the reimbursement front, any color on the European rollout -- I know it's been still very early -- and then any details on the launch plan in the US.
And then, just lastly, if you're continuing to see sequential sales growth for the subcutaneous ICD and whether there may have been any disruption this quarter in the US with the EMBLEM plan launch in Q3.
Mike Mahoney - President & CEO
Sure.
Thank you for the question.
On reimbursement, the majority of the US populations currently covered with the S-ICD, we estimate we're covering about 200 million lives today including Medicare beneficiaries, about two-thirds the Medicaid population, and about 40% of the private-pay market.
We continue to work on the private-pay market and we continue to get big progress there.
So, overall, reimbursement is really not much of a headwind and we continue to make good progress on the private side.
Emblem is really off to a very strong start in Europe.
We're not going to break out the EMBLEM sales in Europe but we received very strong momentum in the early days of launch.
Physicians are very attracted to the 20% center design and longer battery life, and also the ability to track patients remotely with the patient monitoring.
In the US, you're really going to see a launch that'll take place more in the back half of Q3.
So, we're transitioning to that product in the US and you'll see more of an impact in the US in the fourth quarter.
But the product itself, as you know, offers unique features.
It also offers much stronger gross margins that are accretive to the Company and we're excited about the future of it.
Ken, if you had any other thoughts on EMBLEM at all?
Ken Stein - Chief Medical Officer
Yes, I think the only thing to add, again, it's very early but we're pleased with the demand that we're seeing from docs in the US who want to get access to the device as we launch it.
Again, driven by what Mike said -- it's substantially thinner, it's got a 40% longer battery, it's remote monitoring capable, and so folks are interested in it.
And then also, just to highlight, that we're going to continue to develop the clinical data supporting the use of the S-ICD, really as a first choice device for the broad category of patients getting ICDs for primary prevention.
We're really pleased by the pool of data that was just published in the Journal of American College of Cardiology, and recently announced our first patient enrollment in our UNTOUCHED clinical trial, which is really designed to show that outcomes with the S-ICD in the primary prevention population are at least as good as they are with transvenous devices.
Josh Jennings - Analyst
Great, thanks for that.
Then just one quick follow-up, a product specific question or more on the Bayer acquisition and your Jetstream product on the atherectomy side.
There was a MEDCAC meeting yesterday that convened to dive into the peripheral intervention space, and there had been some speculation that atherectomy reimbursement could be called into question.
It seemed benign but can you just give us an idea on how the Jetstream product is doing relative to internal expectations, and maybe any commentary on your outlook for the sustainability of atherectomy reimbursement that's so strong.
Thanks a lot.
Mike Mahoney - President & CEO
Thank you.
In the script we discussed the Bayer integration is going very well.
We won't break out the thrombectomy and atherectomy sales separately, given the size of the PI business.
But that business, the legacy Bayer business, grew double digits, much faster than it had prior to joining BSC given the synergies that we have with our commercial and core portfolios.
So, we're very pleased with it.
We continue to see strong demand for the Jetstream product as well as our below-the-knee product, Rota.
Turning to the MEDCAC panel, we welcome that type of dialogue.
It reinforces the lot of the clinical research and trials that we've invested in for many years in our peripheral business.
And we continue to be confident in the clinical evidence that the PI business generates.
As you indicated in your comments, we don't anticipate a significant change based on that panel.
Josh Jennings - Analyst
Great, thanks again.
Operator
Brooks West, Piper Jaffray.
Brooks West - Analyst
Mike, just following up on the last question, specifically on Lutonix, can you guys give us a little bit better idea of the scale and opportunity for the US drug-coated balloon partnership?
And then just a little bit more detail on how that product was received when you all launched it in Q2.
Mike Mahoney - President & CEO
Yes.
The alliance we have with Bard really works for both companies, given their investment in their Lutonix drug-coated balloon and our capabilities in atherectomy and thrombectomy and some of the complex PI procedures.
The alliance is going well.
It's very early so we're not going to break out separate sales or give hospital account information given the competitiveness of that field.
But I would say the early innings of it are very positive.
The companies are working well together.
Bard has excellent registry data that they presented.
And we have a very strong commercial team with a very wide portfolio to help them to leverage that.
So, we're bullish about the alliance but we're going to steer away from providing specific sales breakouts or account information.
Brooks West - Analyst
Do you see that, though, Mike, as something that could be a $100 million product for Boston at some point?
Mike Mahoney - President & CEO
You'd have to ask Tim Ring and the Bard team that.
Brooks West - Analyst
All right.
And then one for Ken, just on the growth trends in electrophysiology, just a little bit more on what's driving that.
Is that catheters?
Is it the diagnostic piece you got from Bard?
How is the rollout of the Rhythmia system going?
Just any detail on trends you could give us there would be very helpful.
Thanks.
Ken Stein - Chief Medical Officer
We're not going to break it out specifically by product category, Brooks.
Rhythmia, again, we are, I would say, well into the early phase of the launch and really very pleased with how the system is performing.
It is really the first next-generation mapping system for arrhythmia -- high density, high resolution.
I can't tell you the number of cases that I've gone out and been with colleagues where you do the case and you finish and they say -- gosh, we just never could have done this procedure successfully with any of the previous mapping systems.
So, so far everything that we've seen with it during the early launch is validated, all of our thoughts when we purchased the technology.
Operator
Larry Biegelsen, Wells Fargo.
Larry Biegelsen - Analyst
Two questions here.
First, Dan, I couldn't help but mention, you said early on that you've grown 6% or better the last six quarters, per Mike's commentary.
But the guidance assumes a bit of a deceleration.
So, basically are you saying that it's going to be difficult to grow 6% operationally in the second half of this year?
And that $61 million this quarter for interest expense, is that what we should assume for Q4 and 2016 once the AMS deal closes?
And I did have one follow-up question on WATCHMAN.
Thanks.
Dan Brennan - EVP & CFO
Sure, Larry.
In terms of the second-half revenue, I think there's really three key things that are the headwinds in the back half of this year.
The first -- and we mentioned this -- is the IC comps.
When you think of interventional cardiology last year in the second half, that grew 8% in Q3 and 10% in Q4, so 9% overall in the second half.
So, we're up against much more significant comps on the IC side.
We now are looking at CRM, we talk about that being flattish for the back half of 2015.
Obviously feel good about the new launches we'll have in late 2015, in early 2016, and, with Mike's comments, believe we're on the right side of a share gain strategy beyond that.
But the next two quarters should be flattish in CRM.
So, those two.
Plus, when you think of the operational revenue growth rate, in the first half of this year we've had six months of Bayer revenue contribution and in the second half we'll only have two months without a comparable from the year prior.
So, I think those are the real headwinds.
We obviously have tailwinds, as well.
We're excited about the launch of WATCHMAN, we're excited about, as Dr. Stein mentioned, Rhythmia, lotus in Europe, things like that.
But the balance of it we think 4% to 6% is the right range.
Larry Biegelsen - Analyst
But, Dan, the $61 million per quarter for interest expense once AMS closes.
Just lastly on WATCHMAN, I think this has been asked a few different ways on the call, but how common are the local non-coverage decisions in place, that have been put in place for LARIAT?
And how much do you think that's impacting the early uptake?
And that's it for me, guys.
Thanks for taking the question.
Dan Brennan - EVP & CFO
Sure.
I'll take the interest one quickly and then turn it over for the second one.
I would say the net of the new debt at the favorable rates offset by the fact that we have incremental debt for the AMS acquisition probably puts us in a $10 million to $20 million a year increase in overall interest expense on an annual basis.
Mike Mahoney - President & CEO
And, Larry, just on the WATCHMAN, not a whole lot new there.
Just to reinforce -- the vast clinical data that we have with WATCHMAN, I would argue, is quite a bit different than what we've seen with LARIAT in the US.
So, it's difficult to even put those platforms in the same bucket.
The good news is we've enrolled our first 50 centers faster than planned and will likely enroll our second set of 50, with the goal of 100, faster than plan.
And we're delivering very good outcomes and we're receiving strong uptake from it.
We'll get more on the reimbursement pathway, as we mentioned, with the NCD in November and the NTAP, as well.
So, we like the momentum that we have.
And, as Dr. Stein said, we'll continue to layer on more and more clinical evidence on top of WATCHMAN to further differentiate it.
Susan Lisa - VP of IR
