Allergan Announces Acquisition of Kythera Biopharmaceuticals;

Enhances Global Facial Aesthetics Leadership

Dear Colleagues, I am excited to announce that we have reached an agreement to expand our global facial aesthetic offering by acquiring KYTHERA Biopharmaceuticals (NASDAQ: KYTH). KYTHERA, headquartered in Westlake Village CA, is focused on the discovery, development and commercialization of novel prescription aesthetic products. KYTHERA’s lead product is KYBELLA™ (deoxycholic acid) injection, the first and only FDA approved, non-surgical treatment for moderate to severe submental fullness, commonly referred to as double chin. According to a 2015 survey by the American Society for Dermatologic Surgery, 67 percent of consumers are bothered by submental fullness.

This acquisition, if successfully completed, immediately enhances our leading global position in facial aesthetics and also adds an attractive pipeline opportunity, with KYTHERA’s development product setipiprant (KYTH-105), a novel compound for the prevention of male pattern baldness.

This is another example of Allergan being in tune with the needs of our customers and their patients and responding quickly to an opportunity. KYBELLA™ will join our leading facial aesthetics portfolio, which includes BOTOX®, JUVÉDERM® VOLUMA XC, LATISSE® and SKINMEDICA , and will be supported by a strong commercial team. In addition, KYBELLA™ is a pivotal entry point for expanding the use of facial aesthetic products in men, while KYTHERA’s promising pipeline can provide patients with additional aesthetic treatment options.


Allergan has a strong history of innovation and investment in the aesthetics market beginning with the introduction of BOTOX® Cosmetic, which is an iconic brand in the beauty and aesthetics space. We have continued to innovate in the aesthetic market with the introduction of JUVEDERM® XC and JUVEDERM® VOLUMA XC, both leaders within the facial filler market. Now with the addition of KYBELLA™ we look forward to partnering with our customers to create a new contouring market and helping patients improve the appearance of moderate to severe submental fullness.

What happens next? This acquisition is subject to customary conditions, including approval by the shareholders of KYTHERA and expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. The closing of this transaction, if approved and subject to the fulfillment of other conditions, is expected to occur in the third quarter of 2015.

With this combination, we continue to execute on our strategy to build and lead in key therapeutic franchises through innovation and scale. It demonstrates our commitment to making smart, targeted investments that enhance our existing businesses and position our Company for continued long-term growth and success.

This is an exciting day for Allergan, and especially for our Medical Aesthetics teams. We are continuing to deliver on our strategy for growth, and delivering bold ideas in health care. I hope you share in my excitement for our Company and our continued success.

Regards,
