Ladies and gentlemen, thank you for standing by. Welcome to the Boston Scientific Fourth Quarter 2018 Earnings Conference Call. At this time, all participants are in a listen-only mode. Later, we will conduct a question-and-answer session, instructions will be given at that time. [Operator Instructions] As a reminder, this conference is being recorded.

I would now like to turn the conference over to your host, Susie Lisa. Please go ahead.

Susan Lisa

Thank you, Greg. Good morning, everyone. And thanks for joining us. With me on today's calls are Mike Mahoney, Chairman and Chief Executive Officer; and Dan Brennan, Executive Vice President and Chief Financial Officer. We issued a press release earlier this morning announcing our Q4 2018 results which included reconciliations of the non-GAAP measures used in the release. We 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, Financials and Filings.

The duration of this morning's call will be approximately one hour. Mike will provide strategic and revenue highlights of Q4 ‘18. Dan will review the financials for the quarter and then Q1 2019 and full year 2019 guidance and then we'll take your questions. During today's Q&A session, Mike and Dan will be joined by our Chief Medical Officers, Dr. Ian Meredith and Dr. Ken Stein.

Before we begin, I'd like to remind everyone that on the call, organic revenue growth is defined as year-over-year growth, excluding the impact of foreign currency fluctuations and sales from the acquisition of NxThera, Claret, Augmenix, and Symetis in the relevant period to which there are no prior period related net sales. Also of note, 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 products 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 Q1 and full year 2019 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 such differences include those described in the risk factors section of our most recent 10-K and subsequent 10-Qs 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?

Michael Mahoney

Thank you, Susie. Good morning, everyone. Boston Scientific finished up an excellent 2018 where we delivered on our financial commitments and significantly strengthened our portfolio and capabilities for the future.

In fourth quarter ‘18 we delivered 8% operational revenue growth, 7% organic, roughly flat adjusted operating margin and adjusted EPS of $0.39, which includes a $0.01 net tax settlement benefit in the quarter.

Our category leadership strategy continues to deliver strong results in the fourth quarter six of our seven businesses grew faster than the underlying markets. These Q4 results echo our performance in ‘18 overall and for the full year 8% percent operational revenue growth, 7% organic, a 50 basis point improvement or profitability, and adjusted EPS of a $1.47 or 11% adjusted EPS growth to a $1.40 when normalized for the $0.07 tax element benefit for the year. We delivered these results while also generating $2 billion of free cash flow.

2018 results also extend our track record of excellent performance over the five year 2014 to ‘18 period, where BSC has grown sales at the average rate of 8% operational and 7% organic, improvement adjusted operating margin 530 basis points and levers that to drive an average 14% growth in adjusted EPS over the five year period. And this excludes the net tax benefit in 2018.

We believe this five year results provide solid evidence that our strategy of category leadership in key markets and portfolio diversification into higher growth adjacencies continues to deliver differentiated results.

Our goal is to continue to execute against our strategic plan objectives and deliver top tier sales and EPS growth over the next five years. The combination of long-term consistent above market revenue growth, operating margin expansion, targeted double-digit EPS growth and now coupled with the improved ability to deploy our strong free cash flow is what we believe uniquely positions BSC to continue to drive shareholder value.

We're excited about our plans to build upon a global momentum in ‘19 and beyond. We're targeting 2019 operational revenue growth of 8% to 9.5% which includes approximately 110 basis points from acquisitions, resulting in organic revenue growth guidance of 7% to 8.5%. We’re guiding to adjusted EPS of a $1.53 to $1.58 representing a 9% to 13% earnings growth and approximately $2.2 billion in adjusted free cash flow.

I'll now provide some highlights on Q4 ’18 results, along with some thoughts on our ‘19 outlook. Our Q4 - in Q4 8% operational and 7% organic revenue growth continue to be broad-based across our businesses and regions, but most notably this quarter by 9% operational growth in Europe/Mideast Africa, as well as 7% operational growth in both the U.S. and Asia Pac.

Latin America and overall emerging markets had outstanding quarters growing operational revenue 28% and 27% respectively. The MedSurg businesses now are 31% of our revenue mix and they continue to deliver. MedSurg grew 8.9% operationally and 6.2% organically in Q4 and for the full year sales were up 9.3% operational and 8.2% organic.

In Endo we posted 6.6% operational and organic in Q4, and our hemostasis franchise continues to grow double digits in infection prevention and pathology also continue to be very strong. Endo delivered 8.3% operational and organic in ’18 and we expect continue to strengthen our global Endo business in 2019.

Endo has a very rich pipeline and we're launching four new products, including Orca pod single use valves, Orise gel for endoluminal surgery, and SpyGlass DS II with a broader portfolio of solutions for pancreatic biliary procedures. We also remain on schedule for a Q4 launch of our single use duodenoscope Exalt-D, which represents this exciting new phase of our strategy in the therapeutic imaging market.

Our uro and public health franchise also continues excellent performance growing Q4 12% operationally and 5.6% organic. LithoVue, our Single-Use Digital Ureteroscope helps drive double-digit growth in our core stone franchise. Full year ‘18 Uro/PH organic sales grew 6.1%, the additional 250 basis points from M&A for operational growth of 10.6% and importantly the integration work for our tuck-in acquisitions in NxThera, Augmenix, nVision are all tracking as planned.

The Rezum system for the minimally invasive treatment for BPH, had a CPT code take effect January 1st of this year and we just recently published very compelling four year data and durability of symptom relief with a very low 4.4% rate of surgical re treatment and no new adverse events noted between years 3 and 4.

The October acquisition of Augmenix in a SpaceOAR hydrogel which is used to diminish the side effect risks from prostate cancer radiation is off to a strong start and we expanded - as we continue expand market presence and awareness.

Turning to global Rhythm and Neuro, operational and organic sales grew 6.6% in Q4 and 7.6% for the full year. Neuro modulation operational and organic revenue growth grew an impressive 18.9% in Q4 and 22.5% for the year and the continued strength of our portfolio and global commercial execution. We remain very positive on the outlook of the neuromod business in ‘19 due to the continued strength at underlying markets and our innovative portfolio.

In Spinal Cord stimulation WaveWriter is the only platform approved by the FDA to simultaneously provide paresthesia based and sub-perception therapy targeting two different mechanism - mechanisms of action at the same time for patients suffering chronic pain.

This is translated into excellent real work - real world results with 312 patients at the last follow up, 285 were pain free which is a zero pain score and 67% had minimal pain scores of 2 or less. We also look forward to WaveWriter randomized clinical trial data from the COMBO study in the second half of ’19.

Also in DBS, we're excited that we recently received key FDA approvals for our Vercise platform in primary cell and Cartesia Directional Leads and Vercise has now offered in both primary cell and rechargeable systems.

CRM grew both operational and organic sales 1.7% in the quarter and 2.1% for the full year. Q4 growth reflects above market, mid single digit growth in defib, offset by high single digit declines and pacing. Our portfolio in defib continues to drive share gains due to the continued rollout of our RESONATE platform with a HeartLogic, heart failure alert, multipoint pacing and best-in-class longevity within EnduraLife battery technology.

Also Emblem S-ICD also continues to perform very well and grew double digits globally for the full year. And overall we see continuous strength in our defib results in ’19, albeit against tougher comps and some improvement in pacing trends.

In EP we grew sales 8% in the fourth quarter and for the full year up 10.9% operational and organic and the strength of our Rhythmia HDx mapping platform. We continue to enhance our catheter pipeline globally and importantly our two single shot platforms, Cryterion and Apama are on track to launch in Europe by the end of this year, as well as begin enrollment in their IDEs for U.S. approval.

Our cardiovascular group in Q4 grew 8.6% operationally and 7.7% organically. For the full year ‘18 growth of a 7.4% on an operational basis and 6% organic. PI grew 11.2% in the quarter and 9.2% for the full year operational and organic.

The U.S. launch of Eluvia was a driver of the double-digit growth in the quarter. And we also grew double digits and Ranger DCB and interventional oncology. Regionally Asia Pac was a standout in the quarter with mid teens growth in the region.

2019 will really be exciting year for PI as we’re launching multiple new products and also integrating both VENITI and BTG post closure. We continue to see strong physician interest in Eluvia due to its compelling IMPERIAL trial data that was presented at TCT.

Recall the IMPERIAL study demonstrated that patients treated with Eluvia stent experienced half the rate of target lesion revascularization at 12 months versus compared to the Zilver PTX stents and 88.5% patency R rate. Significantly there were no patient deaths in either arm of the study at 12 months. We believe this is a relevant - very relevant considering the recent questions generated by the Katsanos meta-analysis regarding the use of paclitaxel and peripheral balloons and stents.

We believe the FDAs recent letter stating that the benefits of paclitaxel coated devices outweigh the risks, as well as compelling patient level datasets from BSX and others at the LINC conference an ISIS Symposium will serve to reassure physicians and their patients regarding the safety and efficacy of our DCB and DES platforms.

We’re also preparing for the upcoming U.S. launch of our VICI VENOUS STENT, which will be the first on label VENOUS STENT in the U.S. market, and remain on target to close the proposed BTG acquisition in the first half of ’19. With BCG we look forward to enhanced category leadership positions in interventional oncology, arterial and venous therapies.

interventional cardiology continues to grow above market delivering 7.5% operational revenue growth and 6.15 organic in the quarter. For the full year IC revenue grew 6.6% operational and 4.5% organic. IC growth was led worldwide by continued strength in structural heart with WATCHMAN, ACURATE and SENTINEL and double-digit growth in both our complex PCI and PCI guidance portfolios. And this more than offset continue weakness in the drug eluting stent market.

2018 Structural Heart revenue exceeded our guidance of $475 million for the year, an outperformance across the franchises. We target continue strong WATCHMAN growth in ‘19 via increasing utilization with existing customers, as well as geographic expansion where Japan anticipates a Q3 launch and China represents a significant growth opportunity.

In the U.S., WATCHMAN recently received an increase in its primary DRG reimbursement starting last October and we're also pleased that WATCHMAN was just recently included in the new AFib guidelines update, recommending percutaneous LAAO therapy, as a Class 2B therapy for patients with AFiB. At increased risk of stroke, we have contraindications to long-term anticoagulation.

Turning to the WATCHMAN pipeline, we expect a limited market release of the next gen WATCHMAN FLX in Europe in the first half of this year. We also continue to invest in WATCHMAN clinical evidence to support and expand the market, including the recent FLX IDE, the ASAP-TOO study, and the new Option trial.

The Option trial would begin enrollment in the second half of this year and is a head to head study of WATCHMAN versus NOAC in patients following AFib ablation. Study endpoints target noninferiority and stroke rates and systemic embolism with additional superiority endpoint in long-term bleeding.

We're also really pleased with the ACURATE TAVR valve performance in ‘18 and look forward to launching in France with the recent reimbursement approval.

We're targeting launch of the next-generation ACURATE neo2 in Europe in the second half of 2019 and we expect to begin enrollment in our US IDE around midyear.

Our cerebral embolic protection device SENTINEL delivered as planned in Q4 on the back of continued market adoption of protected TAVR and aided by the recently granted New Tech Add-on Payment.

Turning into our LOTUS Edge TAVR platform, we’ll begin a limited release in March in Europe and then the U.S. pending FDA approval. We anticipate initiating a controlled launch in early Q2. We recently began enrolling the LOTUS REPRISE IV study in intermediate risk patients and plan to complete enrollment this year.

Finally in Structural Heart we recently closed on the acquisition of Millipede, a company that's developing an innovative mitral repair platform to treat patients with severe mitral regurgitation. Now with our portfolio of WATCHMAN, ACURATE, LOTUS and SENTINEL and IRIS we're excited about our structural heart capabilities and long-term growth prospects. For 2019 we target structural heart revenue of $700 million to $725 million which represents approximately 50% growth.

So to wrap up, we truly have a very exciting future and believe that we are well-positioned to continue and strengthen our performance track record in 2019, ‘20 and beyond. And for that, I really like to thank our employees and their winning spirit and commitment to patients.

Finally, I'd like to announce that our 2019 Investor Day will be held on June 26th in New York. So please look for additional details to follow in the coming months.

Now, I'll turn things over to Dan for a detailed review of our financials.

Daniel Brennan

Thanks, Mike. Fourth quarter consolidated revenue of $2,561 billion represents 6% reported revenue growth and 8% growth on an operational basis, which excludes the impact of foreign currency fluctuations. Our reported revenue reflects a $43 million headwind from foreign exchange, slightly more than the $30 million to $40 million headwind expected at the time of guidance.

Sales from the NxThera, Claret and Augmenix acquisitions contributed approximately 120 basis points which was in line with our expectations at the time guidance, resulting in 7% organic revenue growth for the quarter at the high end of our organic guidance range of 6% to 7%.

Strong performance for the quarter was once again delivered across the majority of our businesses and regions. On this robust top line we delivered Q4 adjusted earnings per share of $0.39, which represents 14% year-over-year growth, but importantly includes a net tax benefit of $0.01 related to IRS settlement.

Excluding this $0.01 net benefit, our adjusted earnings per share for the quarter would have been $0.38. This $0.01 net benefit in the quarter which I will detail in a moment compares to an expected $0.06 charge related to our tax free investment strategy that was assumed in our Q4 adjusted earnings per share guidance of $0.30 to $0.32.

However, when normalizing for all tax settlement related benefits and expenses, our underlying adjusted Q4 earnings per share guidance would have been $0.36 to $0.38 for the quarter on which we delivered at the high end of the range, driven primarily by strong revenue growth. This result reflects neutral FX for the quarter.

The $0.01 [ph] Q4 net tax benefit is comprised of a $0.05 charge related to our previously communicated tax reinvestment strategy of the Q2 IRS settlement benefit and a $0.06 benefit in the fourth quarter from settling the IRS stipulation of settled issues for the 2011 through 2013 tax years that had not been assumed in our guidance ranges.

Our full year 2018 consolidated revenue of $9,823 billion grew 9% on a reported basis, 8% on an operational basis and 7% organically, which excludes 80 basis points of growth related to the acquisition of Symetis, NxThera, Claret and Augmenix. This growth was right in line with our full year guidance of approximately 7% and represents strong performance on a 7% comp year in 2017.

Full year 2018 adjusted earnings per share of $1.47 represents 17% growth, but importantly includes $0.07 of net tax benefit related to IRS settlement. This $0.07 benefit for the full year compares to our expectation that the tax settlement would be neutral to EPS for the year, so excluding this $0.07 net tax benefit, our underlying adjusted earnings per share would have been $1.40, which is at the high end of our guidance range of $1.38 to $1.40.

This $0.07 net tax benefit is comprised of first, the previously disclosed $0.06 benefit in Q2 from settling the IRS stipulation of settled issues for the 2001 through 2010 tax years. Second, the $0.05 charge in Q4 related to the reinvestment of this Q2 benefit. And lastly, the additional $0.06 benefit in Q4 related to the final resolution of the 2011 through 2013 tax years.

We're pleased to deliver a $1.40 at the high end of our EPS guidance range, while offsetting a $0.04 FX headwind and $0.02 to $0.03 of M&A dilution through operational savings and initiatives.

Turning to the detailed P&L metrics, adjusted gross margin for the fourth quarter of 72.8%, an increase of 20 basis points over the prior year and slightly above the high end of our guidance of 72% to 72.5%, primarily due to the benefit from manufacturing cost improvements with pricing largely as expected.

Q4 adjusted gross margin includes a 70 basis point tailwind from foreign exchange basically in line with the 60 basis point expected at the time of guidance. For the full year 2018 adjusted gross margin was 72.3%, slightly exceeding the approximately 72% adjusted gross margin guidance for the year and representing 20 basis points of improvement over 2017.

We were able to offset 80 basis points of negative impact from foreign exchange with manufacturing cost improvements and a mix benefit from strong performance particularly in our Watchman and Neuro modulation businesses.

Adjusted SG&A expenses were $915 million dollars or 35.7% of sales in Q4, flat compared to Q4 last year and slightly above our guidance range of 34.5% to 35.5%. We remain committed to and continue to realize the benefit of our targeted initiatives focus on reducing SG&A like end to end business process streamlining and automation, including the use of robotic process automation, functional expansion of global shared services and optimizing back office centers of excellence.

These initiatives, plus a strong focus on expense control and improving P&L leverage and Neuro modulation allowed us to decrease our full year 2000 adjusted SG&A rate of 35.4% by 20 basis points compared to adjusted SG&A of 35.6% for full year 2017, all while absorbing dilution from M&A and investing in and launching key products for durable long term revenue growth.

Adjusted research and development expenses were $278 million in the fourth quarter or 10.8% of sales, which is up slightly from Q4 ’17, primarily due to clinical requirements for recent acquisitions and other key pipeline projects.

For the full year 2018, adjusted R&D expenses were $1,52 [ph] billion or 10.7% of sale compared to 10.8% of sale in 2017. Royalty expense was 0.7% of sales in Q4 and the full year 2018, roughly flat year-over-year for both periods. As a result, Q4 2018 adjusted operating margin of 25.5% was roughly flat year-over-year and it was within our guidance range of 25.25% to 26%.

We've also met our full year 2018 adjusted operating margin commitment with a rate of 25.5%, representing an increase of 50 basis points over the full year 2017. We believe this sets us up well to deliver on our additional commitments of 50 to 100 basis points of improvement in both 2019 and 2020, while still investing in acquisitions and key product launches for durable above market revenue growth.

Below the line, adjusted interest expense for the quarter was $62 million compared to $56 million in Q4 of last year and was $239 million for the full year 2018 compared to $229 million for 2017.

Our average interest expense rate of 3.5% in Q4 ‘18 and 3.6% for the full year compared to 3.8% in Q4 last year and for the full year 2017. The increase in interest expense dollars related to additional debt in 2018.

Adjusted other income for the quarter was $4 million compared to adjusted other expensive of $31 million a year ago, primarily due to a net gain uncertain of our available for sale investments in Q4 2018, compared to a net loss a year ago. And both periods also include expenses related to our foreign exchange hedging program.

For the full year 2018 adjusted other expense was $55 million resulting in total below the line expenses of $294 million, which is consistent with our 2017 total below the line expenses of $286 million.

Our tax rate for the fourth quarter was negative 30.5% on a reported basis and 7.3% on an adjusted basis. On an adjusted basis, the favourability in our tax rate was driven by the $0.01 net tax benefit I mentioned at the start of my remarks. This net benefit is comprised of first, the $0.05 charge related to our previously communicated tax reinvestment strategy of the Q2 tax benefit. And second, the $0.06 benefit in Q4 related to the 2011 through 2013 tax years that had not been assumed in our guidance range.

As previously disclosed, we intended to and did reinvest substantially all of the $0.06 Q2 benefits relating to settling the 2001 through 2010 tax years to reduce our operational tax rate in 2019 and beyond by optimizing our structure and leveraging differences in tax rates by jurisdictions. As announced earlier this year, we expect our long-term tax rate before the impact of any stock compensation accounting to be approximately 13% compared to our previously expected rate of 15%.

As I noted, in addition to the benefit received in Q2 and the subsequent reinvestment in Q4, we received a $0.06 benefit in Q4 related to settling the 2011 through 2013 tax year with the IRS. This settlement resulted in a $93 million payment to the IRS in the quarter and a corresponding reserve release that resulted in the $0.06 benefits.

This effectively concludes the IRS transfer pricing case and we do not anticipate any additional payments related to that matter. We encourage you to exclude both tax settlement benefits and related reinvestments when looking at adjusted EPS trends and thus model $0.38 earnings per share for Q4 and $1.40 for the full year

Our full year tax rate was negative 17.5% on a reported basis and 6.8% on an adjusted basis. For the full year, the adjusted tax rate includes a net $0.07 benefit as a result of the $0.06 benefit in Q2 related to the 2001 through 2010 tax years, the $0.05 charge in Q4 related to the reinvestment of that Q2 benefit and the additional $0.06 benefit in Q4 related to the 2011 through 2013 tax years.

Excluding these amounts, our tax rate was approximately 12%, which includes a roughly 100 basis point stock compensation benefit for the year. Throughout 2018, we successfully reduced the approved tax liability on our balance sheet from nearly $2 billion as of December 31 2017 to just under $700 million as of December 31 2018 of the remaining $700 million liability, a little over $400 million relates to the transition tax reserves resulting from US corporate tax reform which is payable over the next seven years. Excluding this reserve, a little more than $300 million remains relating to all tax controversies global.

Finally, Q4 2018 adjusted earnings per share of $0.39 includes the aforementioned net $0.01 tax benefit or a normalized result of $0.38. On a reported GAAP basis which includes net charges and amortization expenses totaling $166 million after tax Q4 earnings per share was $0.27.

For the full year 2018, adjusted earnings per share of $1.47 for $1.40 after normalizing for the $0.07 net tax benefit reflects the high end of our guidance range of $1.38 to $1.40 and a 11% percent growth over the prior year. Notably this 11% growth was achieved while operationally offsetting $0.04 of unfavorable FX and absorbing $0.02 two $0.03 of M&A delusion.

On a reported GAAP basis 2018 EPS was $1.19 compared to full year 2017 GAAP income per share of $0.08 [ph] We ended Q4, 2018 with $1,406 billion and full year 2018 with $1,401 billion fully diluted weighted average shares outstanding. On a GAAP basis, we recorded a net litigation related charge of $85 million in the fourth quarter related primarily to our mesh litigation.

To date, we settled or are in the final stages of settlement with approximately 95% of all our known claims. We believe that the incremental legal reserve recorded in the quarter will allow us to finalize the remaining cases and claims and we continue to target resolution of the mesh litigation during 2019. Our total legal reserve, of which mesh included was $929 million as of December 31, 2018.

In the quarter, we made cash payments of $180 million into the qualified settlement fund for a total of over $600 million for the full year, which is shown as restricted cash on our balance sheet. Our current balance of restricted cash, which is primarily related to the qualified settlement fund is $655 million. As a result for 2019 we have only approximately $250 million left to fund during 2019 and the remaining balance sheet liability will be released as funds are released out of the qualified settlement fund to plaintiffs, which will complete the process.

Adjusted free cash flow for the quarter was $591 million compared to $685 million in Q4, 2017. In the quarter we used cash primarily to fund previously agreed upon legal settlements, as well as business development activities, namely the Augmenix acquisition.

As of December 31st, 2018 we had cash on hand of $146 million. Our full year 2018 adjusted free cash flow of $2.2 [ph] billion, represents 16% year-over-year growth. A very nice leveraging of our 8% operational revenue growth and a 11% adjusted earnings per share growth, excluding the current year net tax benefit.

Our 2018 adjusted free cash flow exceeded our full year guidance of $1.9 billion by approximately $100 million due to a focus on working capital metrics and the timing of certain capital expenditures. We now believe that our 2019 full year adjusted free cash flow will be approximately $2.2 billion, representing 10% growth over 2018 and slightly ahead of our revised goal given earlier this year.

With the proposed BTG acquisition which has not closed, we continue to believe that we have ample capacity to pay down acquisition related debt and continue to pursue business development activities. We'll look to pay down over $1 billion in debt in the 18 months post close of the BTG acquisition, which we believe will put our leverage metrics at approximately 2.6 times EBITDA by the end of 2020, consistent with the2.6 times at the end of 2018. And even with the debt pay down because of our strong cash flow generation profile, we believe that gives us capability of about $1 billion or more in terms of M&A to continue to evolve our category of leadership strategy and do other tuck-in acquisitions, such as the recently closed Millipede acquisition.

As it relates to the BTG purchase price, as you would expect with an exposure to British £, we put in a hedging strategy in place, largely in line with our deal model. As a reminder, we've suspended the share repurchase program for 2019, as a result of the pending BTG acquisition.

Capital expenditures for the full year 2018 totalled $316 million, slightly below our $350 million target. We expect capital expenditures to be in a range of $375 million to $400 million for 2019, as we continue to build capacity, integrate acquisitions and drive continued growth.

I'll now walk through guidance for Q1 and full year 2019. As a reminder, the guidance I am providing does not include the proposed BTG acquisition, which has not yet closed. Upon closing, we'll provide revised guidance.

For the full year, we expect 2019 reported revenue to be in a range of approximately 7% to 9%, which corresponds to year-over-year growth of 7% to 8.5% on an organic basis and we expect an additional 110 basis points contribution from the NxThera, Claret and Augmenix acquisitions.

To be clear, this is the only inorganic contribution of each acquisition and once the acquisition reaches one year post close it is then included in organic. As a result, we expect and have included in our organic guidance range an additional 40 basis points of growth from NxThera post its April anniversary, Claret, post the July anniversary and Augmenix post the October anniversary. This 110 basis points, plus the 40 basis points is equal to 150 basis points of acquisition related revenue which we had been expecting for 2019.

We expect foreign exchange to be a headwind of approximately $80 million to $90 million for the full year 2019. However, as I'll detail next to our hedging program, we expect FX to be neutral to earnings per share for the year.

We expect adjusted gross margin for the year as a percentage of sales to be approximately 72% to 73% for the full year, which assumes a positive FX impact of 40 basis points.

We expect full year adjusted SG&A to be in a range of 34.5% to 35% of sale as we continue to see benefits of the programs currently underway. Full year adjusted R&D is expected to be in a range of 10.5% to 11% and we expect our royalty rate to remain at slightly less than 1% of sales for 2019.

This implies a full year 2019 adjusted operating margin in a range of 26% to 26.5% which is consistent with the improvement goal of 50 to 100 basis points we outlined last September and sets us up well to deliver on our long-term goal of 30% plus adjusted operating margin.

We forecast our full year 2019 adjusted tax rate to be approximately 12% [ph] This assumes an operational tax rate of approximately 13% consistent with our disclosure earlier this year, plus an approximately - approximate 100 basis points of benefit from the accounting standard for stock compensation.

We expect adjusted below the line expenses, which include interest payments, dilution from our VC portfolio and costs associated with our hedging program to be approximately $300 to $325 million for the year. This represents an increase from 2018 adjusted below the line expenses of $294 million as a result of slightly higher debt balance.

We expect fully diluted weighted average share count of approximately 1,409 billion shares for Q1 2019 and $1,410 billion shares for the full year 2019 [ph]. As a result, we expect full year 2019 adjusted EPS to be in a range of $1.53 to $1.58 representing 9% to 13% adjusted earnings growth using 140 as the base, and we expect the FX to be neutral for the year if rates were to hold constant.

On a GAAP basis, we expect EPS to be in a range of 113 to 118. Included in our GAAP EPS guidance is our estimate for the Edwards litigation settlement announced in January, though it is subject to change as we finalize the accounting in the court.

Now turning to Q1, 2019, we expect reported revenue growth to be in a range of approximately 6% to 7%. This represents year-over-year organic growth in a range of 7% to 8%, plus an additional 160 basis point contribution from NxThera, Claret and Augmenix. We expect the foreign exchange impact on Q1 revenue to be an approximate $60 million to $65 million headwind.

For the first quarter, adjusted earnings per share is expected to be in a range of $0.35 to $0.36 per share, representing 8% to 11% growth and GAAP EPS is expected to be in a range of $0.32 to $0.33 per share.

Similar to the full year GAAP EPS guidance included in our Q1 GAAP EPS guidance is our estimate for the Edwards litigation settlement subject to change as we finalize our accounts.

Please check our Investor Relations website for Q4 2018 financial and operational highlights, which outlines Q4 and full year 2018 results, as well as Q1 and full year 2019 guidance including P&L line item guidance.

So with that, I'll turn it back to the Susie who will moderate the Q&A.

Thanks, Dan. Greg, lets open to questions for next 20 minutes or so. Please limit yourself to one question, given the short timing this quarter. Greg, please go ahead.

Question-and-Answer Session

Operator

Thank you. [Operator Instructions] Your first question comes from the line of David Lewis from Morgan Stanley. Please go ahead.

David Lewis

Good morning. Congrats on the quarter and very constructive guidance to start the year. I guess, I'll limit myself to one question and you'll never get to hear my second. But Mike, I'll start with you on strategic activity. So the M&A pace in ’19 or sorry in ’18 was probably the biggest debate on Boston, so as I think about ‘19 and beyond, why should investors not be concerned about the ability to integrate multiple transactions this year, some large some small. And how should we think about the pace of further M&A here in 2019? Thank you.

Michael Mahoney

Sure. Good morning, David. One, I think - I think we've demonstrated very good track record of our ability to integrate acquisitions for Bayer to AMS to Cameron S-ICD and so forth, and you could also throw ACURATE in there. So we deliver on the - our deal models and our team executes them very well. So that’s historically.

Now going forward, we're on track. So this year we have three or four deals that will drive contribution this year with Augmenix, Claret and NxThera. And I'm pleased to say that all those are going as planned. The operations team is doing a great job of ramping up supply. We're driving the appropriate synergies.

And then we have a couple that are a little bit farther out in the pipeline that are doing great clinical work this year, again they're on track Cryo and Apama. And we anticipate Q4 approvals for both those platforms as the clinicals readout. And we have two that are earlier stage nVision and Millipede, which are really early stage still in the R&D phase.

So I think a couple of things. One is they're sequenced in terms of, call it, their maturity. They're distributed across our businesses. And we have the infrastructure in place in our operations supply chain, IT, quality to manage these very effectively.

So you know, I have more confidence now than I did three months ago, given the progress that we continue to make and also we are excited about the potential for BTG closing sometime in second quarter and a lot of efforts I'm planning for that have taken place.

So I have zero concerns about our ability to integrate these deals, while continuing to fuel the growth in our core business. We will see the pace of M&A slow for us in ’19, as we stated before we do have capacity to do some tuck-in acquisitions. But you won't see the volume of activity in ‘19 that we had an ‘18.

Your next question comes from the line of Glenn Novarro from RBC Capital Markets. Please go ahead.

Glenn Novarro

Thanks for taking my question. Good morning, guys. Sounds like the LOTUS launches is right around the corner with Europe next month and U.S. a few months out. So I'm hoping you can talk a little bit about how you're going be positioning LOTUS given you just have a high risk label, your launch of intermediate risk is probably still a few years away and of course, you've got Edwards and Medtronic launching a low risk in the second half of this year. So maybe talk to us about how you market LOTUS to cardiologists, including pricing strategy and willingness to bundle with Claret? Thanks.

Michael Mahoney

Good morning, Glenn. It's Mike here. First of all, we're excited. This has been a journey for us with LOTUS. But the product characteristics are very unique and we're excited about the long-term growth prospects of this platform.

So in Europe, we've got a terrific momentum currently with ACURATE. We're also implanting SENTINEL and there's many physicians in Europe who have been waiting for LOTUS for quite a while. Who in part of various clinical trials and registry programs and are excited to implant LOTUS.

So we've got a winning formula w believe in Europe with both ACURATE and LOTUS and we'll be able to segment those products appropriately and physicians are waiting for LOTUS in Europe.

In the US, we obviously don't have ACURATE, so our 100% focus in the U.S. will be with our protected TAVR with both Claret and also LOTUS and similar to previous comments, we think the differentiated features, the reposition ability of it, the best PVL in the marketplace and also just the clinical experience of those who are involved in clinical trials.

So we believe there will be adequate demand for LOTUS in the marketplace and we want to obviously focus as we begin to launch this product in the second quarter on delivering excellent outcomes and strong experiences, this will be a key platform for us for many years.

So we think the markets there and as you look forward with Boston having Claret and the ACURATE platform where we have a number of new enhancements coming and ongoing enhancements to our LOTUS platform in the pipeline, we are uniquely positioned in this marketplace where we're just now entering the U.S.

We're also in the midst of enrolling our intermediate study today, actually started a couple months ago and we'll finish enrollment without LOTUS by the end of the year.

Operator

Your next question comes from the line of Bob Hopkins from Bank of America. Please go ahead.

Bob Hopkins

Thanks and good morning. So if okay, I just actually want to follow up on LOTUS Edge, given your comments, you're obviously offering some more specific timelines here. So I guess I'm curious what drives the sort of increased specificity on the timelines for approval both and OUS?

And then you mentioned a couple of times sort of a limited launch. And is there something that will hold you back a little bit when you - from a capacity perspective on LOTUS Edge once you get approval. Just curious why it isn't a - you know a full blown launch immediately upon approval? Thank you.

Michael Mahoney

Sure. Morning, Bob. Yeah. So we do have more insight. We think the approval will likely happen potentially early in the second quarter versus midyear. So that's good. And that's very good. And our team deserves it. And that's reflected in the full structural heart guidance we gave and to 700 and 725. And simply speaking with our - with the Lotus valve we want to ensure that we deliver this exceedingly well to get off the - out of the gate strong, to build up a strong reputation for the product in the U.S.

And so like we've commented in the past, this is very unlike, it's not like a DES launch. It's similar to what we did with WATCHMAN, similar that we've done ACURATE in Europe where a key training and proctoring will be part of it. And so we’re not going to launch in - you know hundreds of centers out of the gate, like we would with the DES launch.

So it'll be smartly planned, delivering excellent outcomes, building greater confidence with the physician community, leveraging Claret with protected TAVR the only company that can do that and building momentum. And so you'll see us much like the WATCHMAN launch continue to open centers over time, deliver great outcomes and similar to WATCHMAN we've increased utilization rates each quarter by doing so.

Your next question comes from the line of Larry Biegelsen from Wells Fargo. Please go ahead.

Larry Biegelsen

Good morning. Thanks for taking the question. So Mike you grew about 7.2% organically in 2018 and you're 2019 guidance implies about 7 - 7.8% let's call it the midpoint which is quite bullish. So what's giving you the confidence to guide to an acceleration this early in the year. And any color on which businesses get better, which businesses might slow a little bit in 2019 versus 2018? Thanks for taking the question.

Michael Mahoney

Sure. So we just have a lot of confidence in our team's ability to deliver. I think we demonstrated that over the past five years, I kind of highlighted that in our results. And I think the first thing is we have strong momentum really across the company, MedSurg last year, 8 rhythm and neuromod 8 [ph] it's all organic, cardio 6.

And so we have we have broad based strength across the divisions. We also have very distributed strength across each region. So we're not relying on one region, so we have very good momentum across each region. And we anticipate Japan will be a stronger performance force well in 2019. So I think having that momentum and that diversity of strength across businesses and regions is difficult to do and we have it and we want to continue to pour fuel there.

And then secondly the big thing we have this year is just a lot of momentum in the businesses. Our structural heart guide $700 million to $725 million will drive a lot of growth. Our neuromod business has a lot of momentum and now with the approval of DBS we like that, all though we have tough comps in spinal cord stim.

PI has an exciting future ahead, and in ’19 with the new launches, as well as the pending BTG acquisition. Endo and uro have a lot of portfolio launches and then as well in EP we're excited about single shot capability coming and the ongoing strength of our defib platform.

So I think we just have a lot of momentum there. New product launches and as to David's question earlier, we're very confident we'll deliver on the integrations and that sets us up for a really exciting 2021 and ’22, with those acquisitions and pipeline we're entering into about $20 billion of unserved markets, where today we have about a $1 billion in sales. So I think this M&A that we've done on top of it helps fuel the long-term growth that's differentiated for the future.

Operator

Your next question comes from the line of Chris Pasquale from Guggenheim. Please go ahead.

Chris Pasquale

Thanks. Mike, could you remind us what's your sales strategy will be for LOTUS in the U.S., are you going to have a separate group that is responsible for LOTUS and SENTINEL? And if so where are you in the process of building that out?

Michael Mahoney

Yeah. We’re not going to dig into our commercial strategy in the U.S. We have as you know, a very broad portfolio and lots of capabilities to leverage where appropriate and also to provide unique clinical specificity where needed. You know, we have a large sales team on core DES, on complex PCI, as well as clinical people involved there.

We clearly have dedicated a strong focus on WATCHMAN with clinical. And you'll also have a lot of focus with dedicated people in TAVR and Claret. So they all come under the umbrella of intervention cardiology segments differently based on you know location, but there is a lot of commercial leverage there, synergies with the group, but also maintaining unique clinical focus where needed for those specific types of products.

So I would say in general we're there. We have the commercial team in place. We'll continue to add resources like as we have in structural heart with WATCHMAN and TAVI as we grow it, but the foundation of all that's already in place in the U.S. and in Europe.

Your next question comes from the line of Rick Wise from Stifel. Please go ahead.

Rick Wise

Good morning, Mike. And yes, congrats on another fabulous quarter. Maybe a topic we haven't touched on a little bit, Rezum. You've highlighted all the products that are going to continue to drive growth into - really into the next decade. I'd be curious where does the Rezum stack up on the scale of you know the incredible number of growth enhancing portfolio options. Is it at the higher end of opportunities, where are we now. You have a great four year data in hand. You know, where does it rank, what could it do, what should we expect from this opportunity? Thank you.

Michael Mahoney

Thanks, Rick. Good morning. I think, I know Rezum’s doing - we're very - the team is very committed to Rezum and we had equity investment via an acquisition and I think the team smartly acquired Rezum and recommended it versus a competitor a while ago, on the belief that the stim [ph] based ablation would provide longer term more durable results. And I think that's exactly what the four year data showed. And at the end of the day you know, many had long term results and high safety and efficacy and that's what that that data represents versus its primary competitor.

So I think with a marketplace with the ability to be less invasive and to grow the pie for BPH is extremely unique and then you tuck that into our full portfolio of laser capabilities, as well as our urology sales force with other products, its a very compelling contractual opportunity for us as well.

So I think the product stands alone versus competition. And then you wrap around at the complementary portfolio for contracting is very helpful. So this will be a - make a big impact for our UroPH business. It's -- I don't want to rack and stack them, but we anticipate this will deliver strong growth for us in 2019 and urology will certainly be accretive to our overall BSX growth profile in ’19.

Your next question comes from the line of Vijay Kumar from Evercore ISI. Please go ahead.

Vijay Kumar

Hey, guys congrats again and thanks for taking the question. So one products and one on cap deployment. DBS Mike, you know, you sounded optimistic. Can you quantify on what this means to share gain? So on the spinal cord stim side we've seen 10, 20 points of share shifts. Any comments would be helpful.

And then on the cap deployment side, $2 billion plus of free cash I think, you said a $1 billion of debt pay down. Are we to assume another $1 billion if that is left off for M&A? Thank you.

Michael Mahoney

We'll do Dan's question first. He's lonely here. So we're going to turn over to Dan.

Daniel Brennan

Sure. Thanks for the question Vijay. Yeah, the $1 billion of M&A spend in ‘19 is just the basic math of saying if we did $2.2 billion, little bit of that goes to the qualified settlement funds for finishing out mesh, $1 billion debt pay down, at least $1 billion for M&A. So just simple math that as Mike said allows us to do a small handful of tuck-ins, obviously much less than we did in ‘19. But nice to be able to - still do some M&A – in ’18, nice to still be able to do some in ‘19.

Michael Mahoney

And your first question was on DBS, is that, what it was?

Susan Lisa

Next question, please, Greg…

Michael Mahoney

I have to make a comment on DBS. So as I mentioned in the prepared remarks, the full portfolio is recently approved of the directional lead. And so we just started implanting patients over the past 30 days. So we think that will be a terrific platform for us, it will complement us, yes. We've got tougher comps in SCS this year, so we think the uniqueness of our SCS platform plus DBS will continue to drive neuromod results accretive to the company.

Your next question comes from the line of Josh Jennings from Cowen. Please go ahead.

Josh Jennings

Hi, good morning. Thanks a lot. I just want to ask Dan a question on operating margin guidance, 50 to 100 basis points. Just curious and also on the bottom line, just can you call what the impact of acquisitions are, what the M&A headwind is in terms of what you have to absorb on the margin line and also on the EPS line in ’19? Thanks a lot.

Daniel Brennan

Sure Joshua. As you'd expect there is a little bit of dilution in ‘19 from M&A and obviously since the majority of acquisitions are at our overall adjusted operating margin rate there is dilution at the OI margin rate as well.

I am not going to call the specific, except to say, it's all included within what we think is very strong guidance at 9% to 13% adjusted earnings per share growth off the 140 base and then included in what we think is again very strong operating margin guidance at 26% to 26.5% which is 50 to 100 basis points off of the base in 2018 and it's very consistent with what we've been saying over the last few quarters. So feel good that the whole entire slew that we have adds up to that and feel like that's very strong guidance.

Operator

Your next question comes from the line of Matt Taylor from UBS. Please go ahead.

Matt Taylor

Hi. Thank you for taking the question. So I know you didn't address this explicitly today, but you know obviously with the stronger organic guidance for 2019, you're talking about growth at the upper end of your kind of two year range, that 7 to 10 operational and formally you know 5.5 to 8.5 organic. You did talk about some qualitative things that give you confidence in 2020 and 2021.

Can you say with this kind of a guidance ‘19 does that just give you more confidence in the high end of the range in ‘20 and beyond? Or can you update us on what we should expect for organic and operational growth over the next couple of years?

Michael Mahoney

Morning, Matt. Yeah, we're not going to comment on kind of expanding our guidance beyond ‘19. So something we'll consider in the future for Investor Day. But confident in the ‘19 growth rate we gave and certainly hold true to the ‘19 and ‘20 CAGR growth of 7% to 10% operational that we gave historically.

Operator

Your next question comes from the line of Joanne Wuensch from BMO. Please go ahead.

Joanne Wuensch

Good morning, everybody and thank you for taking the question. It sounds to me like you are likely to have LOTUS at the booth at ACC. Could you please confirm if that's you're thinking and what else we should see from ACC? And then as a secondary, now that Millipede is part of the family what are your thoughts on mitral? Thank you.

Michael Mahoney

So - we do anticipate LOTUS approval as I mentioned likely early second quarter, maybe Ian you can help me specifically at ACC we often showcase WATCHMAN at ACC and we'll certainly showcase our TAVR portfolio, as well as our protected TAVR strategy with SENTINEL. Ian, any other comments on ACC…

Ian Meredith

No, no…

Michael Mahoney

Then maybe comments on Millipede.

Ian Meredith

The answer to Millipede is yes, we see that Millipede is an important foundation for functional mitral regurgitation. Obviously it's part of a bigger strategy, but it's a critical part of the strategy, being the first and most important step in develop - in functional mitral regurgitation repair.

Operator

Your next question comes from the line of Matt Miksic from Credit Suisse. Please go ahead.

Matt Miksic

Thanks for taking the question. So a lot of positive drivers on the top line that you've talked about and we've heard here in Q&A queue. I wanted to follow up with one of the question, one of the comments that you made earlier Dan, in terms of the drivers of your leverage and operating margin improvements, you know, in the past and currently around shared services and robotic process automation.

Can you maybe speak to in round numbers, of course, sort of what that does you know, on a gross basis, we can see what your guidance is for 2019, but what kind of benefit are you seeing from that?

And then maybe which of the acquisitions - recent acquisitions you know, thinking of robotic process automation, some of the back office changes that you're making. Where does that position you to benefit the most as you go through these integrations, maybe also looking ahead to BTG and what the opportunities are there?

Michael Mahoney

Sure, Matt And I would really just ground in guidance for 2019. So if you look at 2018 SG&A was for the full year was 35.4% of sales, the guidance for 2019 is 34.5 to 35. So at the midpoint call that kind of 70 basis points of improvement there. Gross margin obviously contributes, it was 72.3 [ph] in ‘18 and the midpoint is 72.5 [ph] in ’19, so that's kind of the math of how we get to that 50 to 100 basis points of margin expansion.

Specific SG&A, we have a lot of different initiatives going across the divisions, regions and function. I would say that RPA is more of a legacy Boston Scientific thing at this point. We don't descend upon the new acquisitions with RPA. It's more of a back office, things like finance and IT and other functions where we put that in.

It is a big piece of what we're - what we're doing relative to reducing our overall SG&A spend, but it's just one of the components in a lot of initiatives and activities and a roadmap that we have to reduce SG&A as a company over the next two to three years.

Susan Lisa

All right, Greg, we’ll take one more question please.

Operator

Okay. Your final question comes from the line of Isaac Ro from Goldman Sachs. Please go ahead.

Isaac Ro

Good afternoon or good morning, guys. Thank you. Hey, Dan a question for you on the tax rate guidance. There is some new regulations coming through that have a varying degree of impact on companies in the space. I was curious if you could maybe try and quantify for us number one what's assumed in your tax rate guidance for the year as at least in some of these changes. And if you could quantify it in any way that would be awesome? Thank you.

Daniel Brennan

Sure, Isaac. I think I'm going to give you the short answer on that one, both given time and the magnitude of what would be required to go through things like GILTI and hybrid and BEAT and all that. All of what we know today relative to tax reform is included in our 13% operational and 12% all in tax rate for 2019.
