Good day, ladies and gentlemen and welcome to the quarter 3, 2011, Endo Pharmaceuticals earnings conference call. My name is Laura, and I will be your operator for today. (Operator Instructions). Now I would like to turn the call over to Mr. Blaine Davis, Vice President of Corporate Affairs. Please proceed, sir.
Blaine Davis - VP, Corporate Affairs
Thanks, Laura. Good morning, everyone and thank you for joining us. With me on today's call are Dave Holveck, President and CEO of Endo; Julie McHugh, Chief Operating Officer; Dr. Ivan Gergel, Executive Vice President of R&D; Alan Levin, Executive Vice President and Chief Financial Officer; as well as Tony Bihl, Group President of American Medical Systems. After our prepared remarks we'll open the call and take your questions.
I would like to remind you that any forward-looking statements by management are covered under the Private Securities Litigation Reform Act of 1995, and subject to change, risks and uncertainties described in today's press release and in our filings with the SEC. In addition, during the course of this call, we may refer to non-GAAP financial measures that are not prepared in accordance with accounting principals generally accepted in the United States, and that may be different from non-GAAP financial measures used by other companies. Investors are encouraged to review Endo's current report on Form 8-K filed with the SEC for Endo's reasons for including those non-GAAP financial measures in its earnings announcement. The reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures is contained in our sales and earnings press release issued earlier this morning. With that I would like to turn the call over to Dave.
David Holveck - President, CEO, Director
Thank you, and good morning. Endo had a strong third quarter with record revenues of $759 million and adjusted diluted earnings per share of $1.25. These results reflect our continued focus on integration of our newly acquired businesses, solid demand for our products, and our commitment to financial discipline and debt reduction.
Our core business has continued to grow and perform well, with can strong contributions from Opana ER, Voltaren gel and Lidoderm. Sales of branded and non promoted drugs in our legacy business rose 17% year-over-year. Our acquisitions have added growth and created substantial diversification for our Company.
In the third quarter the generics and devices and service segment contributed 44% of Company revenues. You may recall that we significantly increased our financial guidance during our August earning call. Reflecting on our continued focus on robust operational. execution this year, we are reaffirming that guidance for 2011 of $2.72 billion to $2.8 billion in revenue and adjusted diluted earnings per share of $4.55 to $4.65.
Consistent with or strategic objectives, the primary use of our free cash is to pay down debt. During the quarter we made payments of $151 million to reduce term loan debt associated with our recent acquisition of American Medical Systems. Over the last several months we've solidified our expectations for the range of revenue and cost synergies associated with the AMS transaction.
We have taken steps to solidify our relationships with urologists and urogynecologists. Those relationships are an important driver of growth in our urology franchise. We are now calling on a majority of urologists in the United States, up significantly from last year. Importantly there is relatively minimal overlap across the different components of our commercial organization. This, we believe, will ultimately lead to a larger number of more comprehensive relationships with providers and a higher return on our promotional investments.
We have identified potential cross-selling opportunities for the AMS men's health franchise, and Fortesta gel. In addition, the Company is exploring opportunities to expand the utilization of Endocare cryoablation therapy and the AMS green light laser through our HealthTronics franchise. These and other initiatives are now being piloted by our commercial organization, and we expect to see the results of this pilot effort early next year, at which time, we will assess whether these efforts should be scaled nationally.
Looking forward, we believe that having good data is critical to enhancing the organic growth potential of our urology franchise. Data gives us unique insights into our customers, both providers and payers, and helps us chart the path forward in urology. In order to support this strategy, our HealthTronics business recently made two strategic investments in UroChart and Meridian, two profitable providers of electronic medical records software for urologists. These investments will enhance HealthTronics service offerings in urology practice management, and further solidify Endo's contractual relationship with approximately 1,800 practicing urologists, many of whom are new to Endo. Over time, we believe this will give us additional insights into the kinds of best-practice urology solutions and outcomes that are most desirable and meaningful to patients, providers, and payers.
In summary, our outlook for 2011 and 2012 is very positive as we continue to build our brands and grow. Our generics business is outperforming our expectations and we see significant new business opportunities for that business in the year ahead. We believe the combined HealthTronics AMS platform of devices and services should have a record year in 2012, and our pain group is very excited about the potential introduction of crush-resistant Opana ER next year.
Now I appreciate all of the hard work that is reflected in today's financial results, and I'm confident that we have the right vision, strategy, and talent to achieve even greater success next year. Now I'll turn the call over to Alan to describe our financial results in more detail. And then ask Julie to review our commercial highlights. Alan?
Alan Levin - EVP, CFO
Thanks, Dave. Today we reported our third quarter 2011 results, which as Dave noted have shown the strength of our business with outstanding top line growth. I want to provide clarity on some of our P&L items.
For the third quarter of 2011, we reported total revenue of $759 million, up 71% over the third quarter of 2010. Our adjusted diluted earnings per share of $1.25 is an increase of 45% over the third quarter of 2010. Our reported diluted earnings per share of $0.34 is a decrease over the third quarter of 2010, reflecting a charge for impairment of an intangible asset as well as the effects of purchase accounting with respect to our recent acquisitions.
Our gross margin percentage for the third quarter was 71%, reflecting the segment mix in our revenues. On a year-to-date basis, our gross margin percentage was 70%, consistent with our full-year financial guidance of between 69% and 70% as outlined during our second quarter earnings call in August.
Adjusted operating expenses increased to $271 million in the third quarter 2011, compared with $162 million in the third quarter of 2010. The year-over-year increase is driven by the addition of Qualitest and AMS in our operating results following their respective acquisitions.
As a percent of revenue, adjusted operating expenses remain constant at 36% in the third quarter 2011, compared with the same period in 2010. We continue to expect that adjusted operating expenses as a percentage of revenues will decline for full-year 2011, marking the fourth consecutive year of operating expense margin improvement for Endo.
Adjusted net income expense increased to $48 million in the third quarter from $21 million in the second quarter of 2011. The increase is driven by the financing we completed in June, which was associated with our purchase of AMS.
For the full year, 2011, we expect approximately $130 million of adjusted interest expense. During the quarter, we paid down $151 million in term loans. Our debt to EBITDA ratio now stands at 3.5 times, and we expect a further reduction in the fourth quarter, reflecting our focus on cash flow generation and balance sheet management.
Cash flow from operations was just over $200 million for the third quarter. The strength and sustainability of those cash flows supports the pay down of debt which remains a top priority. We remain on track to achieve our target debt to EBITDA ratio of 2 to 2.5 times in 2013.
Our adjusted effective tax rate for third quarter of 2011 was 26%, which benefited from the favorable resolution of certain outstanding audit items. For the full year, we continued to expect an adjusted effective tax rate of approximately 28%, as outlined during our second quarter earnings call in August.
Our diverse generics business had a strong third quarter, utilizing its core capabilities and taking advantage of product shortages and disruptions in the market, particularly in pain products where we have a strong focus and concentration. Our generics business provides sustainable and growing cash flows. And we continue to invest in this segment to further enhance margins and profitability. We remain excited about the growth prospects of this business, which currently has approximately 50 ANDAs under review at the FDA.
Third quarter sales of device and services were also strong, driven by the return of our male incontinence product the AUS 800, in the third quarter, and the solid performance in BPH therapy, driven by an increase in demand for laser procedures.
In women's health we expect a return to growth as we work with physicians to educate them on the outcomes of the recent FDA advisory committee meeting on transvaginal mesh products, as well on the efficacy and safety of our products, and appropriate patient selection.
We are reaffirming our financial guidance for full year 2011. Our guidance includes the acquisition of AMS as well as a strong outlook for our core business. We estimate total revenues to be between $2.72 billion, and $2.8 billion. Additionally, we estimate adjusted diluted earnings per share in the range of $4.55 to $4.65. We now expect reported or GAAP diluted earnings per share in the range of $1.87 to $1.97. Please refer to our earnings press release for additional details on the assumptions contemplated in our full-year 2011 guidance.
Looking to the fourth quarter there are a few items I would like to highlight. On a pro forma basis, we expect to see the top line grow sequentially from the third quarter to the fourth quarter of this year, much as we saw in the same period last year. On an adjusted basis, I would note that the fourth quarter is traditionally our strongest quarter, and we expect solid growth in adjusted diluted EPS sequentially from the third to the fourth quarter. Our guidance reflects the flexibility that we have built into our operating model, as well as the recognition of synergies identified through the continued integration of Qualitest and AMS.
With that, I'll turn the call over to Julie. Julie?
Julie McHugh - COO
Thanks, Alan. Our commercial performance continues to be exceptionally strong, particularly within branded pain pharmaceuticals. Opana ER net sales grew 66% on prescription growth of 56% driven by good formulary access, attractive market growth, and continued growth in our market share.
From a strategic perspective we remain on track with our plans to convert our Opana ER franchise to a new crush resistant formulation in 2012, subject to FDA approval on December 13, which is our PDUFA date.
Voltaren gel net sales grew 35%. The combination of favorable formulary access and successful promotional programs continues to drive demand for Voltaren gel. Lidoderm for the treatment of PHN has net sales growth of 3% year to date versus 2010. Consistent with the expectation that we set, Lidoderm's growth is driven by a combination of modest prescription growth and a modest pricing benefit. The steady performance from Lidoderm coupled with the outstanding growth in Opana ER, and Voltaren gel in the third quarter have combined to lead our branded pharmaceuticals segment to top line growth of 17% versus last year. Now that's 17% organic revenue growth year-over-year in our legacy branded pharma business, absent the impact of any acquisitions.
And the strong cash flows from this core business enable us to pay down our debt while selectively reinvesting across our diversified business to further enhance our operating performance. Today, that diversified business includes our generic pharmaceuticals segment where operating trends remain very strong. For the third quarter of 2011, we reported pro forma sales growth of 17% in generics. This growth was driven by the continued optimization of our commercial portfolio, favorable economics for generic products, as well as our ability to continually capitalize on market disruptions facing other manufacturers.
In addition we continue to explore opportunities to create upside from a consolidated approach with key customers for our branded and generic pain drugs in particular.
Moving on to devices and services segment, we had a solid 6% sales growth on a pro forma basis from the combined HealthTronics and AMS businesses in the third quarter of 2011 versus the prior year. HealthTronics had a fine quarter and is becoming an increasingly important channel for value creation in urology. Dave has already touched on that this morning, so I'll focus instead on results within AMS for our men's health and women's health business lines.
Men's health posted strong results after the AMS artificial urinary sphincter 800 device, used to treat severe urinary incontinence in men, returned to the market following a brief voluntary recall in the second quarter. As a result, men's health grew net sales on a pro forma basis by 21% in the third quarter of 2011 versus the prior year.
Net sales for the women's health business declined by approximately $3 million or 7% on a pro forma basis versus the third quarter of 2010. This followed recent questions by the FDA about the use of surgical mesh products, which we believe were addressed at a September advisory committee meeting. We remain very confident in the long-term prospects for this business.
Finally, we're well underway with two major integration efforts with Qualitest and AMS. We're optimistic that the Qualitest integration will outperform our initial estimates, not only in terms of top-line growth for the reasons I discussed earlier, but also in terms of cost synergies that are being driven by improvements within manufacturing and procurement.
For the AMS integration, Dave already touched on some of our pilot initiatives. I look forward to updating you on our progress with this portfolio of new programs. We're starting to track their performance and are confident in our ability to generate incremental sales growth from the set of unique touch points that we have in urology with our AMS, HealthTronics and branded pharmaceuticals sales teams. These pilots are now launched and our teams are enthusiastic about their prospects. This concludes my prepared remarks, now I'll turn the call over to Blaine.
Blaine Davis - VP, Corporate Affairs
Thanks, Julie. This concludes our prepared remarks. Now we would like to go ahead and open the call to take your questions. Laura?
Operator
Thank you. (Operator instructions). Please stand by for your first question. Your first question comes from the line of Marc Goodman, UBS, please go ahead.
Marc Goodman - Analyst
Good morning, couple of questions. First on the green light laser and that whole marketplace, can you just give us a flavor of what is going on there? The penetration still seems pretty low relative to TURP, so I'm curious what's happening behind the scenes, how good of a growth driver has that become and what you are expecting there? And what kind of resources have you put behind it? And so that's kind of the first thing. And then as you move to the women's health, can you talk about -- are we going to get a bounce back? Are you already seeing a bounce back? Is this revenue number you put up -- I think it was $38 million -- this is pretty low, right? For what you would expect on a quarterly basis? And then on SG&A, I'm just curious about your comment about your flexibility in how EPS is going to be much better in the fourth quarter than the third. So are you saying the SG&A run rate is not the new run rate, that you had extra expenses in the quarter and there are going to be some synergies, so SG&A will come down in the fourth quarter?
David Holveck - President, CEO, Director
Marc, this is Dave Holveck. Let me just give a little topside and then I think both Julie and Tony can add a little bit more of the specific color. The older areas that I mentioned in the pilot opportunities that we're working I think are opportunities that are going to better give us opportunity across the network with HealthTronics on the mobilization area. I think the big area in terms of how we look at sales evolving, not so much the box sales as much as it is the fiber sales, and I think again, we have a greater opportunity now with both companies coming together to take a -- I guess a better focus on the development, if you would, of the procedure and the use of the fiber. On the women's health, again, I think we're in a little bit of a watchful waiting. I think at this point we see opportunities still in women's health and certainly our pipeline, but, again, it is one that we're going to have to work through both relative to the market and dealing with the FDA. Tony if you could take a little deeper dive on some of the specifics relative to laser and women's health?
Tony Bihl - Group President, AMS
Yes, very good, Dave. I think if you look at the important measure on green light laser, we were pleased to see that we saw double-digit growth in fiber usage, and that's really the measure of health long term in that business, is can you place enough consoles and then get fiber usage going? One fiber per procedure really tells you whether you're driving transition from TURP. And so we were encouraged by double-digit growth in that area in the third quarter.
Year-over-year, console placements were a maybe a little bit lower than they were last year, primarily because last year we launched the GreenLight XPS system and there was a certain amount of pent-up demand for those new consoles, so we're not -- I think we're feeling encouraged by the trend that we are on in the green light business. We're doing some things in our European sales organization to get a different kind of specialized focus in that area. So I think it has been a long pull to convert from TURP, but I think we're seeing very, very positive signs, and as Dave said the partnership with HealthTronics, we have already begun to place some of the XPS consoles in HealthTronics partnerships to get them mobilized in a way we hadn't had access to before. So I'm encouraged by that as well.
Dave commented, I think I will support his comment on women's health. It is watchful. What we saw was in the pelvic floor prolapse area, a decline in sales that occurred after the FDA safety notice, but then it flattened, so we haven't seen a continued decline. It dropped, and then it found a new plateau. And we're watching carefully as that goes. We're focusing very much on making sure physicians are comfortable with their training level, comfortable with the proper patient selection. And those who are doing the procedure, the indications we see are those who with comfortable with mesh are continuing to do it, and we're just not going to find a lot of new docs at this point in time who want to start up mesh. We're watching that closely. Positively, though, outside of the US, we're still seeing double-digit growth in our pelvic floor repair products. So it's really a US phenomenon. And so we're focusing lots of attention on that outside of the US market where, again, we continue to see positive messages.
Alan Levin - EVP, CFO
I would add to Tony's comments with regard to the GreenLight laser, as between fibers and consoles, fibers have a much higher gross margin for us, and so at gross margin the contribution from the GreenLight business is stronger than at net sales.
With regard to your question on SG&A flexibility, one of the things I would point out if you look at Q2 SG&A expenditures versus Q3 SG&A expenditures is we do have in Q3 of this year, the first full quarter of AMS revenues and expenses in our P&L, and so sequentially from Q2 to Q3, you do see an uptick. The best barometer of SG&A sales as we move forward into Q4 is really the OpEx spending as a percentage of revenues. We're very focused on margin improvement. We're very focused on the efficiency of our spend, and we expect that we'll see OpEx as a percentage of revenues decline quarter-over-quarter in Q4, and for the full year, 2011.
Marc Goodman - Analyst
Just one quick follow up, and that is, are you expecting in your guidance for the numbers in fourth quarter -- are you expecting much of a bounce back in women's health or are you pretty conservative in the quarter?
David Holveck - President, CEO, Director
I think I'll ask Tony to comment on that.
Tony Bihl - Group President, AMS
Yes, we have assumed that the current plateau level is where we continue through the rest of this year, and we watch for promising signs as we get further into 2012, but we been cautious about the rest of 2011
Marc Goodman - Analyst
Thanks.
Julie McHugh - COO
I just might add that when you look at our third quarter performance and the strength of the performance across all of the major segments, this really speaks to the efficacy of our strategy to diversify our business, and we've now created a much more resilient business overall. And our ability to weather these storms is such that we're just much better positioned today than we were a year ago, so I'm confident that we'll get the women's health business back on track. I'm very excited about prospects of the GreenLight laser, and I'm really excited about the strength of our base business in both branded pharmaceuticals and generics.
David Holveck - President, CEO, Director
And that also played out in our device and services segment with 6% quarter-over-quarter growth, and a big piece of that was the men's health business. So there's diversification across our segments and then even within an existing segment among the business lines.
Marc Goodman - Analyst
Okay.
Blaine Davis - VP, Corporate Affairs
Thanks, Marc. Can we go to the next question, please.
Operator
Certainly. Your next question comes from the line of Gregg Gilbert, Bank of America, Merrill Lynch. Please go ahead.
Gregg Gilbert - Analyst
Thanks, good morning. I have a few. I'll start off on TRF. I wanted to ask you what your level of confidence on a final approval in December on TRF is? Or new Opana CR, if I can call it that. And Julie, what commercial steps are being taken now based on that confidence?
Ivan Gergel - EVP, R&D
Hi Gregg, it's Ivan Gergel, we are confident. We are confident in our NDA filing, and we are very excited about our upcoming PDUFA date. So yes, highly confident.
Julie McHugh - COO
And Greg, we're planning for an approval. We are very actively working with DEA, we have explained our strategy and intention to swap out the old formulation for the new crush-resistant formulation. We're working through a number of scenarios right now in terms of getting our allocation of the oxymorphone quota solidified. Our intention would be to build launch quantities in the first part of 2012, and at the time we have adequate quantities to completely and swiftly switch out the old formulation for the new formulation, we would initiate the launch. And we have the utmost confidence in our ability to launch and convert the market to the new formulation by the end of 2012.
David Holveck - President, CEO, Director
It has always been a great quarter for Opana, up 66%. We see a lot of momentum in this brand. We enjoy great formulary access and very attractive market growth in the long-acting opioid space. And we continue to make market share from competitors. So this is part of what has driven the 17% growth in our branded pharmaceuticals business year-over-year.
Gregg Gilbert - Analyst
Great, if I should shift gears real quick on Qualitest, which has clearly been a bright spot. There have been some recalls, so could you give us some comfort that you have a good handle on the quality issues that may exist there, and that things are getting better overall. With quality.
Julie McHugh - COO
Sure. Yes, it's an important question, and of course, Gregg, quality remains and has always been at the forefront, as a major priority for our enterprise, and we take these recall issues very seriously. And we have identified in each case what the root cause of the issues are. If we haven't yet finalized that, we're in the process of finalizing that. We have corrected the underlying problems. We continue to invest in our operational and quality systems, and we believe that we're in a good place, that we have resolved the issues underlying the recent recalls, and are prepared to move forward and put those behind us. I would add again, that despite the recalls our Qualitest business grew at a 17% pro forma growth level, and we believe that that level of growth is sustainable. We believe our model is solid, and again, we look forward to continuing to invest in this business both in terms of our operations as well as our quality systems and continue the track record into the future.
Alan Levin - EVP, CFO
And margins on the generic business unit for us are also an area of focus. We continue to expect margin improvement over time. Done a lot of work in looking at procurement savings from API this year, as well as efficiencies in our manufacturing process. We continue to invest behind that for good margin improvement, which generates the kind of steady, sustainable cash flows that we find so attractive about this component of our business model.
David Holveck - President, CEO, Director
Yes, and again, the generics business strategically is important relative to another critical piece on our pain franchise, and again in the controlled substance area. So, again, all of the -- what we're seeing here relative to the boost and the significance of growth relative to generics, environmentally, industry wise, coupled with unique features of the franchise we have in pain and also as a controlled substance, we avoid the importation pressure, so we really do feel long term that this is a valuable growth element of our business.
Gregg Gilbert - Analyst
Thanks a lot.
Blaine Davis - VP, Corporate Affairs
Thanks Gregg. Can we go to the next question?
Operator
Yes, your next question comes from the line of John Boris, Citigroup. Please go ahead.
John Boris - Analyst
Thanks for taking the question and congratulations on the results. I think you mentioned in your release that the AMS integration efforts, you are developing plans for delivering revenue and cost synergies associated with the transaction. Can you maybe provide us with an update quantitatively as to what you expect to get on the top line and also in cost synergies, and then secondly, can you potentially provide us with an update on some of your cross selling initiatives that you have ongoing between AMS, the pharma business, and also with that of HealthTronics? Thanks.
Alan Levin - EVP, CFO
Sure. Good morning, John. Why don't I take the financial guidance component, and then I'll ask Julie to comment more about the new initiatives.
With regard to cost synergies, we previously talked about approximately $50 million in synergies from this transaction. We remain on track with that expectation. We have now gone through a planning process that's been quite extensive to identify the specifics around that, and have begun implementing that plan of action. With regard to the top line, we alluded to these pilot programs which are the next important step in our moving forward. We previously talked about mid-single-digit volume growth in our device segment, low single-digit pricing growth, and low single-digit growth from synergies. I think the plans that we have got in place as we look to evaluate pilots and scale will very nicely address our expectations in that regard. Julie?
Julie McHugh - COO
Great question, John. Thank you. And let me -- we have a number of pilots that we have identified in the context of integrating AMS with the legacy Endo business, but what I'll do is focus on the cross-selling pilots that are currently ongoing.
We have cross trained our AMS men's health division on Fortesta gel. And they are discussing Fortesta gel with their customers as part of their overall product portfolio presentation. We have cross trained our pharma urology representatives on the AMS men's health and women's health's businesses. Now, we've done that on a limited basis. We're still piloting these initiatives. But the cross training and the identification of targeted customers has been completed, and we are starting to field those pilots now in the fourth quarter. Our expectation would be to take a readout on how those pilots are performing early 2012, and make some decisions about whether or not to scale them nationally. But I'm hopeful based on some of the early anecdotal feedback that we've heard from the field.
The other cross-selling pilot that we have is working with our BPH laser sales organization and our cryoablation sales organization, to cross-sell those technologies, and, again, that initiative is in the planning phases, and we're hopeful to get that up and running by the end of the year with a readout early next year. So that's just a flavor of some of the pilots. There are a number of other initiatives where we're trying to leverage our core capabilities within the legacy business and within AMS to drive additional upsides, but I'll be able to report out in a more holistic way as we get some of those pilots off the ground.
David Holveck - President, CEO, Director
John, let me just take another point at what Julie said. We talk there about products and cross selling, but I think the other element that we continue to evolve is a greater presence with the urology community, and so the deeper aspects of those relationships beyond just products are critical, and you heard me mention the electronic medical record now as a part of the HealthTronics takes that partnership deeper, into almost a 24/7 relationship. And again, these pilots that Julie framed out are really going to be predicated on understanding how the continuum of care is given and the products that interrelate with that care. So we feel again our position product diversity, along with the element of now data, and our ability to really add even more value content back to that practice is much enhanced in urology from what it was.
John Boris - Analyst
All right. Thanks for that.
Blaine Davis - VP, Corporate Affairs
Thanks, John.
Operator
Okay. Thank you for your question. Your next question comes from the line of Corey Davis, Jefferies & Company. Please go ahead.
Corey Davis - Analyst
Thanks very much. Couple of questions on Opana. In the current quarter, if I did the math correctly, it looks like the value per script dropped from $307 in Q2 to $302. Is that trend likely to continue in Q4? Is there anything obvious that is driving that? Or was it just natural quarter-to-quarter fluctuation?
Julie McHugh - COO
Hi, Corey, it is Julie. The big shift there was essentially a burn down of inventories that were built up in the second quarter, so do we think it's a transitory trend, and we'll get that back to a more even sales trend moving forward.
David Holveck - President, CEO, Director
I think the other consideration is, very, very robust script growth in Opana that continues. We're also seeing a shift in the mix of dosage forms, with a migration that continues from prior quarters towards the higher dosage forms. That's valuable to us. And that's partially offset by our contracting strategy.
Corey Davis - Analyst
And as you shift to TRF next year with the inherently lower gross margin on that product, is that something that we're going to notice in the context of your overall corporate gross margins, or are the improvements that you have talked about with the integrations going to kind of mask that effect?
David Holveck - President, CEO, Director
Well, I think there's just extraordinary flexibility in our business model when we look at gross margins going forward, you have the full year impact of AMS that has very attractive gross margins, and is additive as an updriver next year. We are continuing to see robust growth in our generics business, but we're also capturing bigger synergies from that business, so we'll continue to see margin improvement in that regard. It's just a very diversified business, as we pick up a royalty obligation on TRF, we'll see some modest impact. But I think you've got a lot of offsets there in the mix of segments and products.
Corey Davis - Analyst
Okay. And last question. The REMS program that will be associated with TRF, there any chance for any kind of hiccup there? And can you update us as to where the class wide extended release opioid REMS program is, and is that something that would likely get implemented on to TRF?
Ivan Gergel - EVP, R&D
Yes, Corey, we don't expect a delay because of REMS. We have been working closely with FDA through this process. I believe the class wide program will come out some time in the middle of next year. But once again, we don't expect that to be a delay to our TRF.
Corey Davis - Analyst
That's all I had thank you.
Operator
Your next question comes from the line of Annabel Samimy from Stifel Nicolaus. Please go ahead.
Annabel Samimy - Analyst
Hi. Just while we're on the topic of Opana, can you talk about your pricing plan for the crush resistant? Is it going to be similar pricing to the ER formulation?
Julie McHugh - COO
Annabel, I think what we can say about our pricing strategy for the crush resistant formulation is that it will be on par with our pricing strategy for Opana ER.
Annabel Samimy - Analyst
Okay. Great. And then just moving more to the urology business, can you talk about some of the diagnostics products that you are going to have from HealthTronics, and whether you have been able to use the urology sales force from AMS to start cross-selling those products.
Julie McHugh - COO
Yes, well, we have a -- as you know -- a small but growing anatomical pathology lab solutions business that we came into possession of as a result of the HealthTronics acquisition, and the business is continuing to grow at a nice pace, and we will evaluate moving forward opportunities to cross sell lab solutions as a potential lever for us in the future. I will say that right now, the lab solutions team is highly engaged with the recent strategic investments that we made in health information technology in looking for opportunities to leverage the power of that presence to bring a greater presence for lab solutions, so I'll have more to say specifically on the prospects for lab solutions moving forward, but we're in a nice position right now in terms of the trajectory for that business.
Annabel Samimy - Analyst
Okay.
Alan Levin - EVP, CFO
I would say, the other thing I would add just to go back to Dave's comments about the importance of relationships with urologists, and how that drives the growth in our urology franchise. What you are really seeing play out in our channel strategy is multiple touch points with urologists, whether it's contractual relationships that we have, or the lab services component in the HealthTronics business, or even the new IT investments that we are making. Ultimately we see a greater number of urologists with more comprehensive relationships. That's a big piece of how we see growth enabled in that urology franchise. And that strategy is beginning to play out very nicely. Whether it's in some of the early pilots we have got on upside in revenues in AMS, or some of the organic growth potential that we're seeing in HealthTronics.
Annabel Samimy - Analyst
Okay. And on the AMS business, again, can we talk -- can you talk a little bit about the reimbursement for the GreenLight technology just given physician sensitivity to the level of reimbursement? How does reimbursement for GreenLight compare to some other technologies out there? And are there initiatives to improve that reimbursement?
David Holveck - President, CEO, Director
Tony?
Tony Bihl - Group President, AMS
Yeah, the physician portion of reimbursement for GreenLight is slightly less than the reimbursement for TURP. But rather strong. It's around $700 and -- I don't have the exact number here, but $750-ish, and TURP is roughly $100 more than that. And those have tracked fairly closely together with each other, and what we have done with the GreenLight XPS system is basically to reduce the procedure time to the green light laser in half from the former procedure, so physicians could take in the range of an hour to do a green light procedure, and now we have cut that in half. So a physician thinks of that rate not only from a standpoint of how much it is, but also from a value perspective. We've really reduced their procedure time. So I think we have moved in the right direction.
Annabel Samimy - Analyst
But in terms of other technologies, outside of TURP, like say the button technology, is there some kind of benefit that other technologies may have over you in terms of the reimbursement that they get.
Tony Bihl - Group President, AMS
From a physician component perspective, not dramatically. I believe the button is reimbursed the same as a TURP. It essentially is a TURP procedure that uses a little bit of a vaporization process. But from a physician component perspective, not a significant difference there. And overall from a hospital perspective there's not a dramatic difference in terms of the reimbursement. The green light laser, again, offers -- if you look at the total system, the green light laser offers an opportunity to essentially do a procedure that's an outpatient procedure. Patient comes in this morning, goes home this evening. Versus a TURP where frequently a TURP patient remains in the hospital for longer than one day due to bleeding, et cetera. So what we look at obviously is the total cost of care, and if you look at the green light laser it's a pretty dramatic story. In fact we're doing a number of clinical studies to prove that. But that's how we look at it. So separate the physician component from the total cost of reimbursement. Total reimbursement is rather comparable, but, again, we want to get very, very focused on how GreenLight is much more efficient, much more effective, and cost effective for the healthcare system.
Annabel Samimy - Analyst
Okay.
David Holveck - President, CEO, Director
I would say more broadly across the Company, reimbursement is something we are very well positioned on in our branded portfolio. We enjoy very strong formulary positions for Voltaren gel, Lidoderm, and Opana ER, among other brands. That is part of what has driven our 17% quarter on quarter. In the generics business, obviously this plays -- the generics growth plays very nicely into some of the cost pressures that managed care are seeing. And one of the things that we found very attractive about AMS during our diligence process was the high level of reimbursement that they enjoy for products and services across men's health, women's health, and BPH therapy, as well as some pricing flexibility that is available.
Annabel Samimy - Analyst
Okay. And if I just may ask one more. Are there any further investments that you need to conduct to fill any gaps that you have? Are there any gaps that feel that you have that you need to fill at this point.
David Holveck - President, CEO, Director
The first thing, again, Annabel is paying down the debt. I think as you see where we have these franchises both in pain and urology, there are always these opportunities where we can strategically enhance, again, that position in the practice or within the clinical care setting, and so whether it's, again, licensing or some investments relative to some of the long-term opportunities, it is always that option, but it's execution, pay down the debt, and again put ourselves in a strong position for -- in a very changing environment in the healthcare world. So I think again, we're on the execution, pay down with opportunities, again, to enhance.
Alan Levin - EVP, CFO
We see ourselves in more of a opportunistic mode for our investments. We really don't see gaps as we knit together these different components of the business. Rather we are looking at further enablers to accelerate the growth trajectory, and we're funding all of that out of very strong operating cash flows that still provide, to Dave's point, the ability to meaningfully pay down our debt. I think we paid down $150 million in debt this quarter using about 75% of our cash flow from operations.
Annabel Samimy - Analyst
Okay, great. Thank you very much.
Operator
Thank you for your question. Your next question comes from the line of Shibani Malhotra from RBC Capital Markets. Please go ahead.
Shibani Malhotra - Analyst
Thanks for taking my questions. Just a couple. First on Opana TR. Can you -- we have recently seen some state guidance talking about how insurance companies must provide access to TR formulations of products, and also should not -- these are not going to be automatically substitutable for the non tamper-resistant formulations, so can you comment on how this could change your strategy with Opana TR, and what impact you think this is going to have on the franchise? And then the second point is on Voltaren gel, again, we have seen that some of the generics are conducting long-term clinical studies for the drug. Do you have any plans for a follow-on for Voltaren gel and if so, would this be something that would be shared with Novartis or would this be Endo's alone? Thanks.
Julie McHugh - COO
Okay, well, let me start by commenting on the evolving environment for tamper-resistant formulations. We believe that these state actions that you referenced, Shibani, are right in line with what our thesis is for the importance of crush-resistant formulations, and we believe that what we're seeing is that the government is clear about the challenges with opioid long-term use, and that they see crush-resistant formulations as a step in the right direction to ensuring appropriate use. So we believe our formulation is an innovation that is with the grain of what society is calling for. I'd go on to say that in terms of how we're building out our generics portfolio, we are looking at tamper-resistant formulations of any long-acting opioids. We believe that this will be a cost of entry in the future, and we believe it is the right thing for patients, the right thing for society, and completely consistent with our TRF strategy. With respect to Voltaren gel and generics, we are very encouraged by the recent FDA guidance, regulatory guidance, that requires clinical trials, head to head clinical trials involving the innovator product -- the generic product -- and placebo. We think that sets an extremely high bar for a generic entry, and as a consequence we believe that we're looking forward to retaining exclusivity without a generic competitor on Voltaren gel through 2012 and quite honestly beyond. So we're encouraged by that, and we are continuing our investment in V-gel and believe that we have got some real nice potential in the asset in the years ahead.
Ivan Gergel - EVP, R&D
Hi Shibani. Ivan. Just to echo some of Julie's sentiments, some of the -- there's some data out now looking at some of the new CRF-type formulations that are showing benefit. We believe the benefit of these products, it's aligned with what we have been saying from day one, so we think that certainly FDA feels that way about these products too, based on some of the comments they have made in the past regarding incremental benefit. Regarding the Voltaren gel, we think it's entirely appropriate, the sort of studies that are being asked for a topical agent. This is entirely consistent with what have said for many years, regarding how you need to bring generics through to market for agents. And we believe it is entirely appropriate. That type of study where you need clinical efficacy is exactly the sort of study that should be done to genericize something like Lidoderm as well.
Alan Levin - EVP, CFO
And I think that's the kind of guidance that provides for good, sustainable cash flow generation from this franchise going forward. All of the trends on Opana ER are very bright in terms of increasing market recognition of the value and importance of tamper resistant formulations. And some of the early data that's coming out elsewhere that talks about the ability to reduce abuse and misuse which is a key societal benefit.
Shibani Malhotra - Analyst
Okay. Thanks.
Operator
Thank you for your question. Your next question comes from the line of David Amsellem from Piper Jaffray. Please go ahead.
David Amsellem - Analyst
Okay, thanks. Just a couple. Coming back to the Qualitest business. Obviously a big part is controlled substances. Now should we think of the ANDA pipeline and approvals as diversifying the business away from controlled substances, and also just generally, can you give us a sense of how many approvals we should be thinking about over the next 12 months or so? Thanks.
Julie McHugh - COO
Hi, David, Julie here. Yes, I think the -- we do have a very strong presence, as Dave pointed out, in pain and controlled substances. We also have a market-leading position in liquid-based products. But I would emphasize that in addition to that market leadership position and concentration in those two areas, we also have a broad commercial portfolio, and that's essential to effectively competing in the generic segment. Our ANDA portfolio consists of products not only in pain, but also in CNS, immunosuppression, and other therapeutic areas, so while we will continue to build out our strength in our core therapeutic areas of focus, i.e. urology and pain, we also are building a broad therapeutically based portfolio so that we have lots of levers to pull in the future. So this is a business, our pipeline reflects, again, both ability to strengthen our core therapeutic area focus, but also to diversify and broaden our base. And we believe this positions us very well for the future.
Alan Levin - EVP, CFO
I think the interesting thing, also about our Qualitest business is the strong in line product performance relative to new product performance. We continue to see that trend play out. Qualitest is not the kind of generic house that is subject to the variability in cash flow and profit generation associated with P4 s, it's steady, sustainable, dependable, growing cash flows quarter after quarter, year after year, and we expect that model to continue to play out. We're also playing into an environment now where you are seeing a lot of branded products go off patent. That in turn is causing other generic houses to reallocate production for products. We're beneficiaries of that for some of our in-line products. The business is growing faster than the overall generics industry for the quarter, and we expect good robust growth as we move forward into the fourth quarter and then beyond that in 2012.
David Amsellem - Analyst
And just can you quickly comment on the relative age of the ANDA pipeline, and the quantity of approvals we should be thinking about over the next year or so?
Julie McHugh - COO
Again, it varies across the board, David. I think that what we are projecting for this year is a total of 12 ANDA approvals. And our objective would be to have a ready state of new products going into R&D that we would continue to work with the FDA to work on the backlog on the ANDAs that are currently at FDA, so that we would be able to keep that pace plus or minus a few ANDAs every year.
David Amsellem - Analyst
Okay. And then one last question, if I may, on Lidoderm. Can you provide some depth on the extent to which it is actively promoted and at what point do you consider pulling back or stopping promotion given its maturity and is that something that could happen well ahead of a generic entrant? Thanks.
Julie McHugh - COO
We continue to support Lidoderm for the treatment of PHN and we do have a personal promotional focus behind the brand as well as a nonpersonal promotion effort behind the brand. As you said, it is a mature product and as we look forward to launching the new formulation for Opana we are going to continue to look at the deployment of our resources to appropriately support our core products like Lidoderm while also increasing our investment in our growth assets like the new crush resistant formulation of Opana ER. So we do have flexibility within our sales and marketing infrastructure to be able to flex our resources to focus on our high growth assets and dial back where appropriate on our more mature products. That is something we are constantly looking at. Always looking to optimize the deployment of our resources to drive the top line and to drive the profitability of the franchise.
Alan Levin - EVP, CFO
I would add that we believe that this franchise could remain exclusive into 2015 before any potential generic challenger has clear air to launch a generic, we are confident that the legal and the regulatory hurdles associated with bringing a generic to market pose a significant challenge for any company in that regard. It's a good steady dependable product for us with sustainable cash flows, grows low single digits year after year. We continue to believe that we should support it for PHN as we move forward with our operating model.
David Amsellem - Analyst
Great, thanks.
Blaine Davis - VP, Corporate Affairs
Thanks, David. I think we have time to take two more questions.
Operator
Okay. Thank you. Your next question comes from the line of Michael Faerm from Credit Suisse. Please go ahead.
Michael Faerm - Analyst
Thanks for taking the question. One on Fortesta. Are you satisfied with the pace of the prescription uptake thus far and what are your expectations for the product going forward? And then secondly on R&D expense, it looked like the expense level for the combined companies was maybe a bit lighter than expected. Just wondering if that indicates any reduction in any investment in any specific areas or synergies or otherwise?
Julie McHugh - COO
This is Julie. I will take the first part of the question on Fortesta gel. I'm not satisfied with the current prescription trends Fortesta gel. We are obviously competing in a very competitive market with the testosterone replacement category and as you can expect we have taken a look at what we are currently doing. We have made some adjustments and our expectation is to get that asset back on a growth trajectory and to more aggressively capture market share going forward. So we continue to invest in the business. We have had some early learnings about the nature of competition in this particular class. We have processed those learnings into a new approach and are in the process of getting the product back on track. But I will also just emphasize that we are looking to unleash the power of our broad urology network to provide air cover for Fortesta. And it's a $1.2 billion class, growing at a compounded annual growth rate of 20%. We believe it is a category where we can compete and win and we need to make some adjustments and we will be competitive in the future.
David Holveck - President, CEO, Director
It also plays in some of our key core capabilities on the contracting side. We, as I have said before, we enjoy very strong formulary positioning for our branded pharmaceutical products. We are very pleased with the way we see formulary acceptance of Fortesta. That positions us nicely for good growth as we go forward and of course it plays in the sweet spot in our urology franchise, which is a key focus for us therapeutically.
Blaine Davis - VP, Corporate Affairs
And Mike, can you repeat the second part of your question there?
Michael Faerm - Analyst
Sure, it was on R&D expense. The R&D expense this quarter appeared to be a bit lighter than might have been expected for the combined companies, with AMS that is. So just wondering if that is indicative of any reduced investment in areas or of synergies or other factors?
Alan Levin - EVP, CFO
I think any quarter there is always some variability as we move forward. I think we are tracking very consistently with our guidance with respect to R&D expenditures. We have got a very attractive generics pipeline. We have got some really interesting opportunities in the device space through AMS and we continue to move forward with our branded pipeline, particularly with the recruitment of patients for Urocidin. So I think R&D full year thesis continues to remain intact.
Michael Faerm - Analyst
Great, thank you.
Blaine Davis - VP, Corporate Affairs
Can we go to the last question, please.
Operator
The last question comes from the line of Gary Nachman from Susquehanna Financial Group. Please go ahead.
Gary Nachman
Okay. Thanks. Alan or Julie, there is a big step up going from 3Q to 4Q to get to your revenue guidance. So could you just give a little bit more -- what are the key drivers to get you there and do you think it is more likely to get to the upper or the lower end of the range? What are some of the big variables that we should think about?
Julie McHugh - COO
Well again, I think going into the third quarter we're coming - I mean into the fourth quarter we are coming off of a very solid third quarter and have lots of momentum in both our branded pharmaceuticals and generics businesses. And we are also historically have performed particularly strong in the fourth quarter. So I think that ramp up is not inconsistent with our historical performance but also is consistent with our current growth trajectory across our core businesses.
Alan Levin - EVP, CFO
I think the third quarter is very indicative of strong operating performance across all three segments in our business. I think that is where we are moving as we move into Q4 and then beyond that into 2012. It is sustainable and diversified performance. If you just look at top line growth in branded pharmaceuticals of 17% we are seeing extraordinarily robust growth for Voltaren and for Opana ER. I would expect that to continue as we move into Q4. Lidoderm usually has its best quarter in Q4 and so as we continue to promote that for PHN we will see value in that regard. Generic's growing 17% year-over-year and we have steadily seen an increase in our generic expectations and so we are very encouraged by what we are seeing on the top line there. And in the AMS business again you have got diversity within the product lines but the AUS 800 in men's health coming back on fueled 21% revenue growth so we are very pleased with the resiliency in our portfolio there. So net-net we are very comfortable with the range of guidance that we have provided.
Gary Nachman
Okay. And then just a couple more quick ones. So specifically on generics, what were the market conditions you were able to capitalize on? Is that something that will be ongoing or is it more temporary in nature? And then with HealthTronics, have you guys been able to add new partnerships and just a little bit more on what drove the sequential growth in that business? Thanks.
Julie McHugh - COO
So, in terms of the trends in the generic industry that we're capitalizing on, it involves a number of things. We have certain competitors that are retooling and redirecting capacity from older lines of business to new product launches. Some of our competitors are encountering API shortages. Some of them are encountering manufacturing issues. All of that nets out to a very dynamic generic industry and because we are a very efficient, low cost, high quality manufacturer we are able to pick up some of those business lines and as each of those business lines, the nature of competition changes, with people coming in coming out, we are able to capitalize on that in terms of building market share and taking price where we are able to do that. So we do believe that the generic industry will continue to be in a state of flux over the next several years, and that will be an opportunity for us to continue to grow our business and build our market share and that is why we are bullish about this business.
Alan Levin - EVP, CFO
And I would say on the HealthTronics side, cryoablation therapy is a really fast growing component of our HealthTronic business margin - business model. It's also one of the highest margin components in that model itself. During the quarter we picked up another partnership in cryoablation therapy and that's helped to fuel some growth in the quarter but more importantly it also positions us very well to continue to further drive growth (inaudible - background noise.) As Julie alluded to a little earlier we have got a pilot initiative as part of our AMS synergies to look at cross selling opportunities directly in that space.
David Holveck - President, CEO, Director
I think the other area in HealthTronics is also seasonality. Third quarter being one of hotter areas across the US especially down in the southwest. Kidney stones are a big issue. So that has been another area which influenced their business which, again, we would normally see in the third quarter.
Gary Nachman
Great. Thanks for taking my questions.
Blaine Davis - VP, Corporate Affairs
I would just like to kind of close things out. I'd like to thank everybody for joining us to go through the operating results. I hope the strength of the diversified business model has come through in these operating results and the excitement that we have for the future of this business. Jonathan Neely and myself will be available the rest of the afternoon to take additional questions. Thanks very much for joining us.
Operator
