Richard Gonzalez -- Chief Executive Officer

Thank you, Liz. Good morning, everyone, and thank you for joining us today. This morning I'll discuss our fourth quarter in full-year 2018 performance as well as our expectations for 2019. Mike will then provide an update on recent advancements across the R&D pipeline and Bill will discuss the quarter and our 2019 guidance in more detail. Following our remarks, we'll take your questions. We delivered another impressive year with results well above initial expectations. Adjusted earnings per share in the fourth quarter were $1.90 representing growth of more than 28% versus last year and once again achieving our guidance for the quarter.

Total adjusted operational sales growth of 8.3% exceeded our guidance for the quarter. This growth was driven by a number of products, including our hematological oncology portfolio with global operational sales growth of more than 50% and US Humira which grew more than 9% versus last year. Our international Humira sales were down nearly 15% reflecting the impact of direct biosimilar competition in Europe and other international markets. We also saw a continued strong performance from several other products including Mavyret, Creon, and Duodopa.

AbbVie has demonstrated an exceptional track record of consistently delivering top tier financial performance despite any market or competitive challenges. And 2018 was another clear example of that performance. We continue to drive strong commercial and operational execution resulting in full-year 2018 global operational sales growth of more than 15% and adjusted earnings-per-share growth of more than 41%. As we look at the evolution of our business and of our strategy, we're pleased with the progress that we're making. AbbVie strategy has contemplated biosimilar competition since day one of the launch of this company. Our focus has been on building a pipeline that would allow us to absorb the impact of biosimilar competition and maintain a strong and growing business.

Although our work is never done, we have made tremendous progress building what we believe is one of the industry's most attractive pipelines. In hematological oncology, we have built a powerhouse franchise with Imbruvica and Venclexta. Today, this franchise is roughly $4 billion with more than $1 billion of growth expected in 2019 and significant growth anticipated over our long-range plan. In immunology, Humira in the US will continue to generate strong revenue driving roughly $1 billion of growth in 2019. Since we became an independent company, our research and development efforts in immunology have focused on identifying and advancing new assets that could deliver efficacy superior to Humira and other new agents. Given the importance of this growth platform, we understood that in order to maintain and expand our leadership position, the development of highly differentiated assets was absolutely critical.

We are now confident that with Risankizumab and Upadacitinib we have accomplished our objective. Both of our next generation immunology therapies have demonstrated across multiple clinical trials superiority versus Humira and other competitive offerings. This efficacy was shown across the broad spectrum of patients, including bio-naïve patients at one end of the treatment paradigm and very difficult to treat patients who would fail one or more therapies at the other end of the spectrum. In our hands, these assets have the ability to become the new standards of care in immunology. We expect to launch both Risankizumab and Upadacitinib in 2019 and based on their profiles anticipate broad formulary access.

Beyond our new therapies in hem/onc and immunology, we've also developed other assets that represented attractive, multi-billion-dollar revenue opportunities such as Mavyret and Orilissa. And we have a base business that includes therapies like Creon, Duodopa, Synthroid, and MuPrime. All products we expect will remain durable for many years to come. The event that has for many years concerned investors most has been the loss of exclusivity for Humira. Certainly, the most frequently asked question that we get is what impact will biosimilars have on AbbVie's business? We have long been planning and preparing for the event that is now upon us. We are now facing direct biosimilar competition in Europe and other countries, which represent approximately 75% of our international Humira business or approximately 25% of total global Humira revenues.

As we described on our third quarter call, biosimilar competitors have been more aggressive with Humira than previous anti-TNF biosimilar analogs. But despite the more aggressive discounting, our strategy is working as we had intended. 2019 is a year that should clearly demonstrate to all investors that AbbVie is once again delivering on its commitments. In 2019, we will absorb roughly $2 billion of erosion related to biosimilar competition and roughly $400 million of additional impact following the entry of generic competition brand for Androgel 1.62. We're also facing an extremely difficult comparison period due to the outstanding growth we drove in 2018. And in 2019, we'll also be funding five major product or indicational launches.

Yet despite all of these challenges, AbbVie expects to deliver positive revenue growth and double-digit EPS growth this year. This level of performance demonstrates that the strategy we have in place is working as we planned. And it should reassure all investors of our ability to absorb the impact of direct biosimilar competition while maintaining a strong, growing and vibrant business. Further to that point, our ability to deliver industry-leading EPS growth in 2019 despite the challenges I just outlined, is particularly notable given that this year many of our key pipeline assets will be at the very early stages of their launch trajectory, and therefore providing minimal offset to the biosimilar impact. Given their product profiles, we expect these pipeline assets will grow substantially over the next several years and provide significant offset to the 2023 US biosimilar event.

So, as I said, we're pleased with the progress, with our strategy, and investors should view 2019 as a real test of that strategy. In summary, this is an important time for AbbVie. The continued momentum of our US business and our hematological oncology franchise combined with the launch and ramp of several new products will allow us to grow through biosimilar impact in 2019 just as we had predicted. We've demonstrated a strong track record of managing and overcoming challenges and our expected performance in 2019 is another clear example of that. And while we're certainly proud of what we've accomplished in the first six years as an independent company, I can tell you we remain focused and committed to delivering on our long-term vision for the company. Sustain top tier performance. With that, I'll turn the call over to Mike for additional comments on our R&D programs.

Michael Severino -- Vice Chairman and President

Thank you. 2018 was a very productive year with significant pipeline advancement, including numerous development and regulatory achievements and successful data readouts across our pipeline. We secured regulatory approvals for several programs, including Venclexta in the broad relapse refractory CLL population and conditional approval for Venclexta in newly diagnosed AML patients ineligible for intensive chemotherapy. Approval for Imbruvica in combination with Rituxan as the first chemotherapy-free combination treatment for Waldenstrom's. The ninth FDA approval for Imbruvica overall. And for Orilissa, for the management of moderate to severe pain associated with endometriosis. We completed registrational studies and submitted regulatory applications for our two next-generation immunology therapies. Risankizumab in its initial indication, psoriasis, and Upadacitinib in its first indication, rheumatoid arthritis. Across each of the four phase three studies in the pivotal program for psoriasis, Risankizumab showed consistent, high, durable rates of skin clearance.

Based on these results, we believe Risankizumab has the potential to significantly improve upon current treatment options for both bio-naïve and TNF inadequate responder patients with moderate to severe psoriasis while offering the convenience of quarterly dosing. Our regulatory reviews are well under way with approval decisions expected in the second quarter. With Upadacitinib, our goal is to deliver a differentiated patient to RA patients. We designed a broad and comprehensive set of six pivotal studies in RA, enrolling nearly 5,000 patients across multiple populations, including two studies with biologic comparators. We evaluated Upadacitinib head-to-head against the standards of care in RA, including Methotrexate and Humira. And in a broad range of patient types within the moderate to severe RA segment.

This includes immunotherapy treatment in patients who are naïve to methotrexate as well as studies in very difficult to treat patients who have failed one or more biologic therapies. Across the select clinical program, both doses of Upadacitinib performed extremely well and demonstrated a strong benefit-risk profile. Based on our analysis of the data generated across the registrational program, we believe that 15-milligram dose represents the best dose for the RA indication as it delivered maximal efficacy across a wide range of studies, drove strong results on important structural endpoints, and demonstrated superiority to Humira in our head-to-head study. Thus, this dose provides the differentiation we were seeking when we designed our program.

Our regulatory submissions are currently under review and we expect to approve all decisions in the second half of this year. In addition to the successful trial readouts for Upadacitinib and Risankizumab, we also reported positive data from several phase three studies in other areas of our pipeline, including Elagolix and uterine fibroids, Venclexta in frontline CLL. And data from several important phase three studies in our frontline CLL program from Imbruvica, including results from the ECOG alliance and ILLUMINATE trials. Data from these three studies show treatment with Imbruvica alone or in combination significantly prolonged progression-free survival compared to therapy, such as FCR, BR, and Gazyva plus Chlorambucil and previously untreated CLL patients. We also initiated several phase three programs, including studies for Upadacitinib in atopic dermatitis and ulcerative colitis.

In addition to the progress we made across our late-stage programs, we also advanced a number of early stage assets in the mid-stage development, including our jack BTK program in RA and our CD40 program in ulcerative colitis. And, we transitioned several pre-clinical programs into human trials, including our novel PNF steroid conjugate and our ROR gamma T programs. Clearly, we made tremendous progress advancing our pipeline in 2018. And, we look forward to many important pipeline milestones in 2019 as well. In hematologic oncology, we'll see data from several phase three studies for Venclexta this year, including results from the Bellini trial in relapsed refractory multiple myeloma and from our two frontline AML studies. As well as the detailed data from CLL14. Our phase three study for Venclexta in frontline CLL.

These data and subsequent label augmentations will build upon the body of evidence demonstrating Venclexta's potential as a foundational treatment option across a number of hematologic malignancies. Earlier this month, the Venclexta CLL14 data were selected for FDA's real-time oncology review program. This program is aimed at expediting the review and approval process for supplemental drug applications. Results from CLL14 have already been shared with the FDA, which was part of the agency's evaluation process leading to the decision to offer the real-time review. Very soon, we will begin submitting data as part of the review process and expect an approval decision later this year.

We look forward to bringing this new treatment to market in the frontline CLL population. In the area of solid tumors, we'll see data this year from our phase three study for Depatux-M in newly diagnosed glioblastoma multiforme. This is an extremely difficult to treat form of brain cancer with a very high unmet need and limited treatment options. We have seen encouraging trends in overall survival in our phase two study and second line GBM and look forward to the results of our frontline phase three study to define the future regulatory path for the program. We also expect several assets from our early stage solid tumor programs to transition to proof of concept studies this year. And we'll share data from these programs as they mature.

In the area of immunology, as I previously mentioned, we expect regulatory decisions later this year for Upadacitinib in RA and Risankizumab in psoriasis. In addition to their leave indications, we continue to make great progress with Upadacitinib and Risankizumab in a number of other immune-mediated conditions. This year, we'll report mid-stage data for Upadacitinib and Axial SpA and we plan to begin phase three development in giant cell arteritis. Overall, this year we'll have ten active ongoing registration enabling programs for Upadacitinib and Risankizumab.

We're also making good progress with our early stage immunology pipeline, which includes programs aimed at redefining the standard of care in autoimmune diseases. We have several promising assets, including ABBV-323, our CD40 antagonist. ABBV-3373, our PNF steroid conjugate, and ABBV-599, our combination jack BTK inhibitor. And in the area of women's health, following completion of the pivotal trials for Elagolix and uterine fibroids, we plan to submit our regulatory application around the middle of the year.

So, in summary, in 2018 we made tremendous progress advancing our pipeline, achieving a number of key clinical and regulatory milestones across all of our therapeutic areas. And we expect 2019 to be another very productive year for our R&D organization. We look forward to updating you on our pipeline progress throughout the year. With that, I'll turn the call over to Bill for additional comments on our 2018 performance and our 2019 guidance.

Bill Chase -- Executive Vice President of Finance and Administration

Thanks, Mike. Today, I'll review the highlights of our performance for the fourth quarter and full-year 2018 and then walk through our 2019 outlook. As Rick mentioned, we have completed another year of outstanding performance delivering top and bottom line growth that ranks AbbVie among the very top of our industry peers. We reported adjusted earnings per share of $7.91 up more than 40% compared to 2017 and one $1.44 above the midpoint of our initial expectations for the year. For the year, adjusted revenues were $32.7 billion, up 15.2% on an operational basis excluding a nearly 1% favorable impact from foreign exchange.

For the fourth quarter, total revenues were $8.3 billion, an increase of 8.3% on an operational basis excluding a 1% unfavorable impact from foreign exchange. This performance reflects double-digit underlying volume growth offset by approximately 2.5 points of negative price. Global sales of Humira were $4.9 billion in the quarter up 1.4% operationally. In the US, Humira sales increased 9.1% compared to the prior year, reflecting high single-digit volume growth plus price. Wholesale or inventory levels remain below half a month in the quarter. International Humira sales were $1.3 billion in the quarter down 14.8% operationally, reflecting the introduction of biosimilar competition across Europe and other international markets.

Global Humira sales for the full year 2018 were $19.9 billion reflecting operational sales growth of 7.4%. Full-year sales of Humira in the US grew more than 10% and international Humira sales approached $6.3 billion performing in line with our expectations. Hematologic oncology global sales were $1.1 billion in the quarter up 50.3% on an operational basis driven by the continued strong growth of both Imbruvica and Venclexta. In the quarter, Imbruvica net revenues were $1 billion primarily driven by continued uptake in the frontline CLL segment. Venclexta revenues were $124 million in the quarter driven by continued uptake in the second line plus setting as a result of our mid-year approval in the broad relapse refractory CLL segment. For the full year, our hem/onc global revenues were $3.9 billion up 45.8% on an operational basis.

Global HCV sales for the fourth quarter were $862 million. Mavyret continues to perform well, holding roughly 50% market share globally. For the full year, HCV sales exceeded $3.6 billion and was above our previously communicated guidance. We also saw continued double-digit operational sales growth for both Duodopa and Creon. Turning now to the P&L profile for the fourth quarter, adjusted gross margin was 79.8% of sales, up 80 basis points compared to the prior year. This was inclusive of the year-over-year benefit related to the termination of certain royalties with Humira, partially offset by the dilute of impact of partnership accounting. Adjusted R&D was 16.5% of sales supporting our pipeline programs in oncology, immunology, and other areas.

Adjusted SGNA was 21.6% of sales, an increase of 30 basis points versus the prior year, reflecting continued investment in our on-market products, as well as investment in advance of several upcoming product launches. The adjusted operating margin was 41.7% of sales in the fourth quarter, an improvement of over 100 basis points versus the prior year. Net interest expense was $319 million, and the adjusted tax rate was 9.1% in the quarter. Fourth quarter adjusted earnings per share, excluding specified items, were $1.90 up 28.4% year-over-year. In the quarter, we recorded a net charge of $2.75 per share related to the partial impairment of intangible assets acquired as part of the Stemcentrx acquisition. The net after-tax impact of this impairment and the related adjustment to contingent consideration liabilities was $4.1 billion. This one-time net charge has been excluded from our adjusted EPS results.

As we look ahead to 2019, our full-year adjusted EPS range is $8.65 to $8.75 reflecting growth of 10% at the midpoint. Excluded from this guidance is $1.26 of known intangible amortization and specified items as well as non-cash charges for contingent consideration adjustments related to the expected approval of Risankizumab in the first half of the year. On the top line in 2019, we expect revenue growth of approximately 1% on an operational basis. At current rates, we would expect foreign exchange to have just less than 1% unfavorable impact on reported sales growth. Included in our revenue guidance are the following assumptions for our key products. In 2019, we expect US Humira to once again be an important contributor to our performance with revenue growth of approximately 7%. We expect 2019 international Humira to be down approximately 30% on an operational basis reflecting the impact of biosimilar competition outside of the US.

For our hem/onc franchise, we expect global revenues of approximately $5.1 billion contributing more than $1 billion of growth. This includes Imbruvica global revenues to AbbVie approaching $4.4 billion with US sales growth of approximately 21%. For Venclexta, we expect sales of approximately $725 million. We expect global HCV sales of approximately $3.3 billion in 2019 with a roughly flat performance in the US and international sales of approximately $1.7 billion. For Orilissa, we expect sales of approximately $200 million. We are pleased with the early stages of the launch and expect demand to ramp given recently increased formulary access which now stands at approximately 70%. For Creon, we expect approximately 10% sales growth.

For Duodopa, we expect revenues approaching $500 million. For Lupron, Synthroid, and Synagis, we expect sales to be roughly flat year-over-year. And for Androgel, we are forecasting sales of approximately $100 million following the entry of generic competition for Androgel 1.62. Finally, we are expecting a regulatory decision for both Risankizumab and Upadacitinib later this year. We will provide specific guidance for these assets following their respective approvals.

Looking at the P&L for 2019, we are forecasting an adjusted gross margin ratio of above 82.5%. This profile reflects a year-over-year benefit of the [inaudible] [00:29:20] royalty reduction as well as the impacts of partnership accounting. We are forecasting R&D expense of approximately 15.5% of sales reflecting funding actions supporting all stages of our pipeline. We are forecasting SGNA to be approximately 20.5% of sales in support of five major product or indication launches. For 2019, we are forecasting an operating margin ratio of just above 46.5% roughly 200 basis points above prior year inclusive of the required investment on our new product launches. We expect net interest expense approaching $1.3 billion and we model a non-GAAP tax rate just above our full-year rates in 2018.

Regarding our first quarter outlook, we expect adjusted earnings per share between $2.05 and $2.07, excluding approximately $0.31 of specified items. We anticipate first quarter revenue of approximately $7.7 billion. At current rates, we would expect foreign exchange to have an unfavorable impact on reported sales growth of approximately 2% in the first quarter. For US Humira, we expect sales of approaching $3.2 billion. We expect international Humira sales of approximately $1.2 billion assuming current exchange rates. And for Imbruvica, we expect sales of approximately $1 billion. Moving now to the P&L for the first quarter. We are forecasting adjusted gross margin ratio in line with full-year guidance and spending levels slightly favorable relative to the full-year profile due to investment timing.

We expect an adjusted tax rate just below 8% on the first quarter, lower than our expected full-year rate reflecting the fact that the tax impact of equity compensation is most pronounced in the first quarter of each year. In summary, AbbVie has once again delivered an excellent quarter and full-year results. We've driven top tier revenue in EPS growth while also advancing our strategic priorities and our pipeline. And our strong growth prospects have enabled us to position the business for yet another year of double-digit earnings growth in 2019 despite biosimilar dynamics and the required investments to support several major product and indication launches. We are very pleased with AbbVie's strong performance. And with that, I'll turn the call back over to Liz.

Questions and Answers:

Liz Shea -- Vice President of Investor Relations

Thanks, Bill. We'll now open the call for questions. Operator, first question, please.

Operator

Thank you. And as a reminder, to ask a question, please press *1. Our first question today is from Steve Scala from Cowen.

Steve Scala -- Cowen -- Analyst

Thank you very much. In 2019, if Humira grows one billion in the US but declines two billion OUS, it would have to grow 11% in 2020 to hit the $21 billion guidance figure. Is that still your expectation?

Secondly, do you anticipate an FDA ADCOM for Upadacitinib? And then lastly, perhaps in part due to AbbVie's openness to do a deal and its desire to have another therapeutic vertical, there's been some speculation that AbbVie might pursue a big deal even in an unfriendly way. Considering the many moving parts at AbbVie, what is your appetite right now for a big deal and would you consider an unfriendly one? Thank you.

Richard Gonzalez -- Chief Executive Officer

Steve, this is Rick. I'll cover one and three and then Mike can cover number two. So, first of all, if you look at Humira, obviously, we continue to see strong growth in the US. We're continuing to see the biosimilar effect play out. We've assumed within our planning period of 2019 that we'll see some continued erosion from a price standpoint across the time period that is greater than what we currently have as currently in place. So obviously, we'll have to see how that plays out. In the end, if we look at the long-term targets that we put in place, we still feel confident in the overall long-term targets, whether or not one product is slightly different than another. I mean, we'll see how that plays out, but we obviously feel confident in what we have committed to and we maintain that commitment.

As far as the appetite for a big deal, I can tell you that is not something that we contemplating.

Michael Severino -- Vice Chairman and President

This is Mike, I'll take number two. With respect to UPA and the potential for an ADCOM, I think it's important to keep in mind that we're in the very early stages of our regulatory review. But if you look at the practice of this review division, it's common for filings like this, for new molecular entities in RA to go to an ADCOM. So, it's certainly possible. But we'll have a much better idea once we're further along in the review process.

Operator

Thank you. Our next question is from Andrew Baum from Citi.

Andrew Baum -- Citi -- Analyst

Thank you. Apologies if I missed the early parts of the call, but just in terms of what's embedded in your 2019 adjusted earnings guidance for Humira in international markets, if you could give us additional color on that that would be great. Second, you recently had a management reorg. Could you talk to that in relation to also planning and the organization? And then finally, you disclosed a couple of negative headlines in Q phase three, the leuprolide trials over a year ago. I haven't seen the data for that. Its border interest is what it's for -- when might we see that data being presented? Many thanks.

Bill Chase -- Executive Vice President of Finance and Administration

Hi, Andrew. I'll start with your first question. It's Bill Chase. Our guidance around Humira for 2019 is in the US strong growth 7% is what we are recommending that you model. Outside of the US, obviously, with the advent of biosimilars we are forecasting a decline and currently, we view that as about 30% on an operational basis.

Richard Gonzalez -- Chief Executive Officer

Andrew, this is Rick. I'll cover number two. We did announce a change in our organizational structure at the executive level. The purpose of that change -- we've operated now for six years with a fairly broad management structure reporting into me. The purpose of the change really was to narrow the focus of the direct reports that I had that ultimately would allow us to focus and execute even at a higher level around where our strategy is going forward.

In addition, we have a very talented executive leadership team and we wanted to get those people some additional experience in other areas and this will allow us to be able to do that. I've heard all the rumors about potentially me retiring. I can tell you they are not true. As many of you probably know, I retired once, and I can tell you I'm a heck of a lot better at running AbbVie than I was at retirement. Hopefully, that clarifies it.

Michael Severino -- Vice Chairman and President

This is Mike. With respect to the leuprolide data. So, we announced those top climbers, ultimately, we had them. We're committed to publishing all results and making the data available. I don't have a specific meeting or specific timeframe to point to here on the call today. But we will be making those data publicly available.

Operator

Thank you. Our next question is from Geoff Meacham from Barclays.

Geoff Meacham -- Barclays -- Analyst

Hey, guys. Thanks for the question. Just had a few on Humira. For OUS, are there countries that still need to be contractually locked in for '19 and with your new guidance bill, are there resets at year-end looking to 2020 and beyond? And then, when you guys talk about the US, the strategy seems to be moving Humira to later in the paradigm across different markets. And then, you patent Risa upstream. As you guys get closer to launch, are you thinking about -- how is the contracting gonna make this happen? Is it just about discounts or rebates or are there more novel strategies under discussion? Thanks, guys.

Richard Gonzalez -- Chief Executive Officer

This is Rick. I'll cover those first two. There are still some countries where obviously it is still evolving. The southern European countries are probably the most significant and to some extent, Germany. I'd say we've haven't seen a lot of movement in place over the last 60 days or so, but we are anticipating -- and as I've said, we built into our forecast some incremental decline in place just to make sure that we felt comfortable with where potentially could go. As far as other countries in 2020, the majority of the volume doesn't come under additional biosimilar exposure in 2020. The more significant countries are in 2021. There is some but the majority of it occurs in 2021, not in '20.

As far as what you described as contracting dynamics, I think if you talk about our go-to-market strategy for these products, we're not in a position nor from a competitive standpoint do I think we would want to talk about it at this point where our go-to-market strategy is. But I think in general, the way you can think about these assets -- and it's certainly the way we're thinking about it is -- now that we've produced the data on Upa and Risa across the broad range of indications. It has validated for us that these assets ultimately are superior to what's out there today.

And clearly, as I indicated, we've now had enough data across a broad range of clinical trials and across a broad range of patient population from naïve patients to TNF inadequate responding patients. That we know these assets will ultimately be able to deliver significantly superior results through both Humira as well as other assets that are out there, other medicines that are out there. And therefore, the logical strategy with these assets is to position them to be lead products in the marketplace. We would obviously put a contracting strategy in place that would be consistent with that approach and obviously, we will fund those launches in a way to be able to drive that approach in the marketplace both in the US as well as outside of the US. And we expect the uptake to be consistent with the profile of those assets.

Operator

Thank you. Our next question is from Tim Anderson from Wolfe Research.

Tim Anderson -- Wolfe Research -- Analyst

Thanks so much for the questions. I have a question on spending infrastructure over the long-term. So naturally, the big concern is Humira biosimilars and how that impacts with P&L and what other levers you could potentially pull is cutting cost. At some point in the future, and I know you've given long-term operating margin guidance, but can you give us kinda more detail on how you see SGNA and R&D evolving over time. I'm wondering if you can cull large amounts of spending out of these line items. It seems like that could be challenging in the context of still investing heavily in the I&I space with your other assets. So how much is spending a major lever that can be pulled in the future?

And then the second question just goes back to Humira international. In October, you revised down your erosion guidance and now just three months later you've revised it down again in terms of international performance for 2019. Can we be confident that you won't have to revise it down yet again at another point in the current year? Thank you.

Richard Gonzalez -- Chief Executive Officer

Tim, this is Rick. I'll cover most of those questions and Bill can fill in with anything I haven't covered. So, let me start with what you described as the guidance. And let me go through the history of the guidance because I think it is important to lay out. We came out with the original guidance back in 2015 and that was based on what we saw in the marketplace primarily at the time, Remicade, and then followed it with Enbrel. And we updated it I think in 2017 specifically what we thought.

And then, from that point forward, we said we needed to see what it would look like going forward. On the third quarter call, from the best of my recollection, we were three weeks into biosimilars, right? And we made it fairly clear, and I think if you go back and you read the transcript, it's fairly clear. What we were giving the market was a snapshot of what we saw at that time. And in fact, I think I said at the time, you should not assume this as guidance. It's likely to get worse. So, hopefully, we were clear at that point. As far as specifically to your question. As I indicated, we have built in further erosion that we haven't seen yet.

So, in the number that Bill described, the 30-31%, which is roughly five points above where it was before, that has some assumed erosion that has not occurred. Look, what we're giving you is our best estimate of what will happen. Obviously, this is driven by not us, it's driven by competitors and their behavior. And so, ultimately, it's not like we have a crystal ball that we can predict exactly what they do. What I can tell you is this; we have a high level of confidence in delivering the bottom line performance that we described to the market and we have enough ability to be able to do that and we have a high level of confidence in double-digit EPS.

So, that's what you should rely upon. Whether or not things move around a little bit, they could. But to the best of our ability, we're forecasting what we believe, and I think I'd say, it's a reasonably high probability that those numbers should be accurate. As far as spending in infrastructure, obviously, as we look at what's going on in these various markets, just like we do with any product that experiences an LOE, we flex as quickly as possible the spending around those products to be reflective of what's appropriate in that particular market and under those circumstances.

And we're certainly doing that with Humira right now in the international markets. But obviously, one of the things that's important to remember here is we've either just launched or will launch over the course of the next 12 months four major products that have multi-billion-dollar potential. If you think about Venetoclax, it's in its very early stages now, it's just received the broad label in CLL and in AML, so it's essentially a relatively small product that's now growing rapidly. Orilissa, we just launched that product. We're gonna launch Upadacitinib. We're gonna launch Risankizumab. These are all multi-billion-dollar assets. We're gonna fund those to the extent that is appropriate to drive the potential because that is ultimately what will offset and absorb the biosimilar impact. And so, that's the strategy that we'll drive.

Bill Chase -- Executive Vice President of Finance and Administration

The only thing I'd add is, as you look at the 50% -- the big part of the story from here on out is gonna be obviously P&L leverage given the robust sales that we're expecting once these new products get up to into their ramps. So, 2020 should be a sales expansion year. But even then, we're always gonna be thoughtful about how we deploy our resources. You look at this year on an operational sales increase of 1%, we're still delivering 200 basis points of op margin progress.

I think that's pretty good. And we're appropriately funding those new product launches. The only way you can do that is being thoughtful about your overall book of SGNA and do some prudent reallocation and obviously, you could infer that that's happening in the numbers this year. So, look, we're always gonna be thoughtful on spend but the real way to get to an improved op margin is gonna be through sales leverage, P&L leverage and we're gonna remain focused on making sure that we appropriately fund new opportunities.

Richard Gonzalez -- Chief Executive Officer

The only other thing I'd add is; I think it's important to keep in perspective how this business is performing. You have a business here that for six years has delivered top tier performance. Last year they grew the bottom line 41%, through the top line 15%. If you look at 2019 and you look at that guidance range at the midpoint being 10%, you back out the share repurchase, which is about three or four points of it, it says that the underlying business despite taking almost a $2.5 billion hit, is growing at 6-7% from an EPS standpoint. If you adjusted for the $2.5 billion, the bottom line is growing at 23%.

There aren't many businesses around here that have that kinda performance. At the top line, the same thing. If I adjust the top line, which is roughly 1%, if I adjust it for the $2.5 billion, the rest of the business is growing high single digits. And so, you certainly want to make sure that you're in a position that you can continue to drive this business in a way that it can continue to perform because that is ultimately the way you're gonna absorb biosimilars. And I would tell you that despite the fact that these biosimilars have priced more aggressively than we thought, or the analogs would've suggested, the business is absorbing them effectively. And that's what the strategy was designed to do.

Thank you. Our next question is from Geoffrey Porges from SVB Leerink.

Geoffrey Porges -- SVB Leerink -- Analyst

Thank you very much for taking the questions. First, could you just talk a little bit about pricing, Rick? What assumptions about pricing have you baked into your guidance for particularly US revenue growth in 2019? And what do you think of the political risks that could affect that outlook?

And then secondly, could you talk a little bit about the launches of Upa and Ris in 2019? Could you help us understand what, if any ability you have, to prepare for those launches in your discussions with payers? Should we be expecting them to launch with the same sort of trajectories as their preceding products in that class or should we push those launches out to 2020 as you get into that payer cycle? Thanks.

Richard Gonzalez -- Chief Executive Officer

I think as you look at pricing, we have now -- we were one of the companies that made a commitment that we're gonna do one price increase per year a couple of years ago and it would be below double-digits. And we've obviously ironed that going forward. So, we've done the price increase for this year. You saw that it was lower, 6.2% roughly. So, I think you know what the pricing will be in 2019 because we have no intention of doing another price increase in 2019.

I think if you look overall, yes, the industry has adjusted to some extent. I believe to the environment as it relates to pricing. Our business is not a business that is driven to any great extent by pricing. We're fortunate that we have innovative products and volume is the vast majority of it. Bill, you're probably talking about -- well, in 2019, you're probably talking about overall negative price.

Bill Chase -- Executive Vice President of Finance and Administration

For the entire book, including the US, low single digit.

Richard Gonzalez -- Chief Executive Officer

So, it's not heavily reliant upon price nor last year was it heavily reliant upon price. So, I think we're comfortable with where we are from a pricing standpoint. We don't see any exposure related to that. As far as Upa and Risa, obviously, we will want to get these products on formulary as broadly and as quickly as possible. I would say that's an area that we have a team that is good at doing that, effective at doing that. And so obviously, based on the fact that we assume Ris is gonna be approved here in the not too distant future, we have to be in a position where we are in discussions.

Nothing that I'm gonna update you here on but I would say the operating assumption that is probably a good assumption is that we will end up with broad coverage of these assets. As far as the ramp is concerned, I think I understood your question and I'm gonna answer it in the backdrop of what I thought you asked. What I thought you asked is, how would I compare these -- the prior competitive launches.

I can tell you that we would expect, like other launches, they will take a little bit of time in order to ramp, but I'd say also with our expertise in this area and the portfolio of assets that we have and the profile of these particular drugs. From a clinical standpoint, I would expect that these assets will be able to drive significant share over time. And a significant capture of new patients and switching patients and that'll certainly be the strategy we have in place to drive a significant part of those available patients to these better assets.

Operator

Thank you. Our next question is from Chris Schott from JP Morgan.

Chris Schott -- JP Morgan -- Analyst

Great. Thanks very much for the questions. My first one is just following up on the longer-term international Humira business, so beyond 2019. Do you see 2019 as a peak rate of erosion for that business and then maybe a more moderate step downs beyond 2019? Or could we see several years of this more severe erosion level as we just think about kinda getting past this year and the outlook for that business?

My second question was on capital allocation. And I guess as the more challenging your Humira environment change or alter your priorities at all, specifically, the company's been very active on the sheer repo front over the past few years. How do you balance that repo with priority with diversification given some of these Humira dynamics that we're seeing playing out? Thank you.

Richard Gonzalez -- Chief Executive Officer

So, I think I would see that you have gotten the vast majority of the impact from a price erosion standpoint in 2019. But, remember what I described before. We have factored into our plan further erosion as you go throughout the year. So, there'll be some annualization impact that you would obviously see in 2020 if that is to kinda play out the way that we have planned for. And then, you will have some countries that will go biosimilar in '21 that have not gone biosimilar to date. And they would obviously have some impact, although I would say most of those countries it should be a lower impact but we're gonna have to see how that sorts itself out.

So, certainly, I don't think you'll see a step down that's as significant as we've seen in the first year because there have been very aggressive prices in certain countries and so you'll obviously get to the point at which the biosimilar players have gotten to what they believe is the floor where they wanna operate. And so, I think you should see it moderate, I guess is the best way to describe it. As far as capital allocation versus share repo, if you look at how we've operated this business since day one, we've obviously been very vocal about how we view the business and what our mission is and what our vision is for the business. And that is to drive long-term, sustainable top tier performance.

And in order to do that, you have to invest in the business appropriately. We've obviously invested significantly in R&D since we launched the company we grew R&D significantly. We've obviously been very active from a PD standpoint. At the same time, we have a business that generates a tremendous amount of cash flow and we generated enough cash flow that we had opportunities to be able to also do share repurchase and other methods of being able to return capital to shareholders such as a growing dividend. And so, we tried to balance those things in a way that is appropriate but never to not strategically invest in the business. That's always our first priority.

If you look at the share repo that we've done in 2018 as an example -- I think the thing you have to remember and the numbers I quoted, you a minute ago I think are reflective of that. Yes, share repo is driving some of the EPS growth if you look at the midpoint. But it's relatively modest, 3-4% of that. It wasn't driven for the purpose of doing that. Ultimately, we did the share repo and we announced it I believe in that first quarter call that we were gonna do a significant amount of share repo because of tax reform, and we thought that was fundamentally important to be able to return cash and capital back to shareholders.

So, we did it long before we ever knew what the biosimilar pricing would be. So, it wasn't driven for the purpose of driving the short-term versus the long-term. Having said all that, we continue to be active in looking at opportunities that are out there. We have a very active business development group. We look at things that are small, things that are medium, things that are large, and we certainly have the wherewithal to be able to do things. If we can find something that's strategically fit and we could get a good return on that, I can tell you we would act, and we would act swiftly in order to do that. I think you've seen us do that before.

If we could find another Imbruvica or we could find another Risankizumab out there, I can tell you we would aggressively pursue that. And so, we fundamentally have a pipeline that we believe has the ability to do what we strategically intended it to do, and that is to absorb the impact of biosimilars. Our focus is to ramp that pipeline as rapidly as we possibly can and make sure we're in a position to be able to continue to drive strong growth in the business.

Thank you. Our next question is from Jason Gerberry from Bank of America.

Jason Gerberry -- Bank of America -- Analyst

Hey, good morning, and thanks for taking my questions. First one, just coming back to US Humira, just curious -- the softening of the 2019 number. Just sort of curious; to what degree is that cannibalization from the next generation immunology brands? Just sort of curious if that's a factor of it really was just sort of maybe the moderation of pricing. And then my second question; I guess with Jamie no longer on these calls, I'll ask the question. Rick, how are you defining a large M&A deal? That's a question that we're getting from investors. So, if you can maybe put some parameters around it that'd be great. Thank you.

Richard Gonzalez -- Chief Executive Officer

Last time I defined a large bolt on it had an undesirable reaction in the marketplace. Look, the largest transaction that we've done so far has been Pharmacyclics. That's what I view as the size of a roughly bolt on kinds of transaction. When I say a large deal, I'm thinking about a very significant kind of deal. Merger type deals. We're not contemplating anything of that magnitude at all. US Humira, you wanna cover that, Bill?

Bill Chase -- Executive Vice President of Finance and Administration

Yeah, sure. So, if you look at US Humira, we're guiding 7% in 2019. That's coming off of a number in '18 of 10% and as I think you pointed out, a lighter price increase on the year. So, if you really factor out the change in pricing year-over-year, you'll see that the business is still performing very, very well. Volumes are still pretty much pegged right where they have been historically. You've got the law of large numbers here, a little bit. But I wouldn't read much into underlying dynamics on Humira other than continued strong performance in the US.

Liz Shea -- Vice President of Investor Relations

Thanks, Jason. Operator, we have time for one final question.

Operator

Thank you. Our final question today is from Katherine Xu from William Blair.

Katherine Xu -- William Blair -- Analyst

Good morning. I'm just curious about the hem/onc franchise strategy. Apparently, [inaudible] [01:00:51] and [inaudible] are doing well. What are you thinking about boosting over that? There is, of course, the pediatric taste that you used to have with other companies and returned and there's also the seller therapy that was a very big space. Just wondering about your general strategy there?

Michael Severino -- Vice Chairman and President

This is Mike, I'll take that. With respect to our hem/onc franchise. Both Imbruvica and Venclexta are performing very well. Both from a data perspective and from their trajectories in the marketplace. One of the things that I think is particularly attractive about those two with respect to our franchise is that they cover a broad range of heme malignancies. They work well together in areas like CLL and mantle cell lymphoma and CL. And then they also have some unique areas.

For example, like Venetoclax in AML. So that's gonna be an important area for us going forward. It's now annualizing over $4 billion. It's growing at a robust rate. So, I think you can expect to see us continue to work in this area. We're gonna look at how we not only continue to develop those mechanisms in areas like multiple myeloma for Venclexta. But also, how from our earlier pipeline we can add additional mechanisms so that'll further strengthen our position in hem/onc.

There are a lot of things in our early now approaching mid-stage pipeline, working apoptosis in other areas that could apply there. And of course, we're looking more broadly than that. You've seen us do early stage deals but early stage deals that give us access to interesting technologies. We have some very early plays that could be aimed toward cellular therapies. And to other mechanisms that could further develop that franchise.
