Thank you, Kris, and good afternoon, everyone. Thanks for joining us. We have a lot of great news to share with you today. We'll be discussing the Meda transaction, reviewing highlights from 2015 and providing guidance for 2016 with or without Meda, given that we expect to close by the end of Q3 this year.
Turning first to the transaction we just announced. We have agreed to acquire Meda, a leading international specialty pharmaceutical company, via a recommended public offer and a transaction valued at $9.9 billion. We are receiving, including synergies, approximately $1.1 billion in EBITDA. In addition to the Meda Board's recommendation, I'm pleased that Meda's 2 largest shareholders, representing approximately 30% of outstanding shares, had irrevocably committed to tender into the offer and intend to remain long-term shareholders of the combined company.
The strategic rationale for a combination of Mylan and Meda has long been very clear. In addition to being partners since 2011 on EpiPen in Europe, we have had numerous discussions over the years about other ways to collaborate, including our proposal to acquire the company in 2014. Since 2014, the rationale for this combination has only been further enhanced by Meda's acquisition of Rottapharm and our acquisition of EPD, with the ability to leverage this infrastructure, especially in Europe and emerging markets.
This combination continues to accelerate the execution of the vision and strategy we've laid out over a decade ago. The global competitiveness of our industry and consolidation of our customer base continues to drive the importance of scale, and this combination creates a global pharmaceutical leader with 2015 combined revenues of $11.8 billion and adjusted EBITDA of $3.8 billion, a portfolio of more than 2,000 products and critical mass across all commercial channels, including a $1 billion OTC business.
By offering one of the industry's broadest portfolios of products across all customer channels, including Rx, GX and OTC, we'll be able to mean even more to our customers, which is increasingly important in light of the evolving payer and distributor environment. Geographically, we're gaining more balance and expanded global footprint with an even stronger presence across Europe, a leading U.S. specialty business and an expanded presence in emerging markets, including several new and attractive ones such as China, Southeast Asia, Russia, the Middle East and Mexico.
Together, we will also become a leader in the global respiratory allergy market and achieve scale in many other therapeutic areas, including dermatology and pain, offering us even greater opportunities for growth in these categories. As you know, we have always been very active in looking at various opportunities. We revisited the Meda opportunity this past summer and continued conversations throughout the fall. During this time, the fundamentals and the inherent value from this combination become even more apparent the more we dug into the business during due diligence, leading to our announcement today.
This combination will create tremendous value for our shareholders as well as other stakeholders. On a cash flow basis, at 12.9x 2015 adjusted EBITDA and 8.9x adjusted EBITDA with synergies, we expect to achieve substantial annual operational synergies of approximately $350 million in year 4. We believe we are paying an attractive multiple that is in line with market precedents for such scarce, high-quality assets.
The transaction is expected to be immediately accretive to Mylan earnings, with accretion increasing significantly after the first full year 2017 as synergies are realized. Most importantly, the transaction creates the opportunity to achieve $0.35 to $0.40 accretion in 2017 and to accelerate achievement of our previously stated $6 adjusted diluted EPS target to 2017 versus 2018.
We expect to see accelerated earnings and EBITDA growth going forward as well as substantial cash flows and enhanced margins. Even with the financial commitment to this transaction, we still have ample financial flexibility for business development activity, for additional share buyback, all while keeping our commitment to investment grade.
Giving our long history together, we know Meda's business, their people and their culture extremely well, and we believe that we will be able to quickly and smoothly integrate this business. I look forward to working with and welcoming Meda's leadership team and talented workforce to our organization. They have built a terrific company, and I believe we will be able to achieve great things together.
With that, let me turn now to the highlights of our performance during 2015. Mylan again had an outstanding year, delivering exceptional financial results, while continuing to execute on our long-term growth drivers.
On the top line, we generated adjusted total revenues of approximately $9.4 billion despite considerable FX headwinds, representing a year-over-year constant currency increase of 28%. On the bottom line, adjusted diluted EPS came in at $4.30, a 21% year-over-year increase even after absorbing $0.11 of that FX headwinds, which put us at the high end of our guidance range. We also had a record year with respect to cash. Adjusted free cash flow more than doubled, and adjusted free cash flow stood at 87% of adjusted net income.
In addition, we closed on 2 strategic acquisitions during the year. First was Abbott's EPD Business, which has surpassed our growth expectation and is proving to be a solid revenue contributor. Second was the Famy Care transaction through which we are now well on our way to creating a leading women's health care franchise.
Also noteworthy during 2015 was the further strengthening of our EpiPen franchise and our continued efforts to increase awareness and expand access to the anaphylaxis market. One point of note, while we saw higher sales of EpiPen due to higher volumes that resulted in part from the Auvi-Q recall. We saw the same net payer pricing dynamics that existed throughout 2015, and we don't expect material changes to the environment in 2016.
We also continued to make good progress across our strategic growth drivers. In our respiratory program, we recently announced that we submitted our ANDA for generic Advair. We are extremely excited about this opportunity, and we continue to believe that Mylan will be the first company to bring generic Advair to the U.S. market in 2017.
And building on our successful Biocon partnership, we announced earlier this year an exclusive global agreement with Momenta that expands our portfolio of biologics with up to 6 additional products and broadens the scope and scale of our capability. The combination of this program and our Biocon partnership positions Mylan as a worldwide leader in the biologics space.
In summary, 2015 underscores the power of the exceptional global platform we have built and our ability to absorb volatility and maximize opportunities. It also reflects the superb execution and teamwork by Mylan's employees around the world. And on behalf of the Board of Directors and our entire leadership team, I'd like to thank them for an outstanding year and a job very well done.
Now, turning to 2016. We look forward to delivering yet another year of outstanding financial performance. On the top line, we expect growth of approximately 16% compared to 2015, and a guidance range of $10.5 billion to $11.5 billion. On the bottom line, we expect growth of approximately 16% year-over-year, with guidance range for adjusted diluted EPS of $4.85 to $5.15. Our guidance ranges include a quarter's worth of contribution from Meda. However, we are also committed to these ranges without Meda.
And as mentioned earlier, we see opportunity to accelerate the achievement of our $6 adjusted diluted EPS target to 2017. I'd now like to take a minute to thank John, who is retiring from Mylan on April 1, for his service to our company. During his 6 years with us, John helped shape the company's ongoing transformation into a global leader in health care. We are all wishing him the very best as he enters this new chapter of his life.
Before I turn the call over to Tony, I'd also like to take a moment to congratulate him on being appointed Mylan's Chief Commercial Officer, which became effective earlier this year. Tony has been with the company for nearly 20 years and most recently successfully led our largest commercial business, the North American region, for the last 4 years. In his new role, Tony oversees all of our commercial businesses around the world.
With that, I'll turn the call over to him to discuss the performance of our core business during 2015.
