Our Company
We are a research-based biopharmaceutical company that discovers, develops and commercializes innovative medicines in
areas of unmet medical need. With each new discovery and experimental drug candidate, we strive to transform and simplify care
for people with life-threatening illnesses around the world. Gilead's primary areas of focus include human immunodeficiency
virus (HIV), liver diseases such as chronic hepatitis B virus (HBV) infection and chronic hepatitis C virus (HCV) infection,
oncology/inflammation and serious cardiovascular and respiratory conditions. We have operations in North and South America,

We were incorporated in Delaware on June 22, 1987. Our principal executive offices are located at 333 Lakeside Drive,
Foster City, California 94404. The telephone number of our principal executive offices is (650) 574-3000.
The HCV Market
We estimate that approximately 7.9 million individuals in the United States, France, Germany, Italy Spain, United Kingdom
and Japan are infected with HCV, with the majority of those being genotype 1-infected HCV patients. Of the estimated 4.1 million
people in the United States infected with HCV, we estimate that approximately 1.7 million are diagnosed with HCV,
approximately 385,000 are in care and approximately 54,000 are receiving treatment.
On December 6, 2013, we received U.S. Food and Drug Administration (FDA) approval of Sovaldi (sofosb
®
uvir 400 mg)
for the treatment of HCV. We estimate that approximately 70% of the patients who used Sovaldi in the fourth quarter of 2013 were
infected with genotype-1 HCV infection and that these patients typically took Sovaldi in conjunction with peg-interferon alfa and
ribavirin.
The HIV Market
In 2011, we launched Complera /Eviplera
®
(emtricitabine 200 mg/rilpivirine 25 mg/tenofovir disoproxil
®
fumarate 300 mg),
our second single tablet regimen for the treatment of HIV for patients new to antiretroviral

therapy. In December 2013, we received FDA and European Medicines Agency (EMA) approval for Complera/Eviplera to be
used by certain adult patients switching from another stable antiretroviral regimen. In August 2012, we received approval from the
FDA for Stribild (elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir disoproxil fu
®
marate 300 mg) , our third
single tablet regimen for treatment of HIV. The EMA approved Stribild in May 2013. We estimate that as of approximately
sixteen months after the launch of Complera and Stribild, 62% of the patients in the United States taking each product was
switching from another HIV treatment regimen and that 38% of each such patient population was new to HIV treatment.
