May 25, 2017

(PRINCETON, NJ, May 24, 2017) - Bristol-Myers Squibb Company (NYSE: BMY) announced that the U.S. Food and Drug Administration (FDA) accepted a supplemental Biologics License Application (sBLA) that seeks to extend the use of Opdivo (nivolumab) to patients with hepatocellular carcinoma (HCC) after prior sorafenib therapy. The FDA granted the application priority review and previously granted Opdivo orphan-drug designation for the treatment of HCC. The FDA action date is September 24, 2017.

Bristol-Myers Squibb (BMS) has a robust clinical development program in Opdivo monotherapy and in combination therapy with other therapeutic drugs in a variety of tumor types overseas, including glioblastoma, small cell lung cancer, urothelial cancer, hepatocellular carcinoma, esophageal cancer, colorectal cancer, gastric cancer, blood cancer, etc.

In Japan, Ono Pharmaceutical Co., Ltd. (ONO) launched Opdivo for the treatment of unresectable melanoma in September 2014. ONO received an approval for additional indication of unresectable, advanced or recurrent non-small cell lung cancer in December 2015, unresectable or metastatic renal cell cancer in August 2016, relapsed or refractory classical Hodgkin lymphoma in December 2016 and recurrent or metastatic head and neck cancer in March 2017. In addition, ONO has submitted supplemental application for additional indication of gastric cancer, and is conducting clinical development program including esophageal cancer, gastro-esophageal junction cancer, small cell lung cancer, hepatocellular carcinoma, glioblastoma, urothelial cancer, malignant pleural mesothelioma, ovarian cancer, biliary tract cancer, etc.

In Japan, ONO and BMS (and BMS Japan subsidiary BMSKK) have formed a strategic partnership that includes co-development, co-commercialization, and co-promotion of multiple immunotherapies for patients with cancer.

Application is based on results from the Phase 1/2 CheckMate -040 trial

(PRINCETON, NJ, May 24, 2017) - Bristol-Myers Squibb Company (NYSE: BMY) today announced that the U.S. Food and Drug Administration (FDA) accepted a supplemental Biologics License Application (sBLA) that seeks to extend the use of Opdivo (nivolumab) to patients with hepatocellular carcinoma (HCC) after prior sorafenib therapy. The FDA granted the application priority review and previously granted Opdivo orphan-drug designation for the treatment of HCC. The FDA action date is September 24, 2017.

"We believe the FDA acceptance of our application for Opdivo with priority review status is an important recognition of the significant unmet need for patients with HCC, which is often diagnosed in the advanced stage when treatment options are limited," said Ian M. Waxman, M.D., development lead, Gastrointestinal Cancers, Bristol-Myers Squibb. "We are committed to exploring new treatment options for these patients and look forward to working with the FDA to potentially extend the use of Opdivo as a treatment option in this setting."

The submission was based on data from the Phase 1/2 CheckMate -040 study investigating Opdivo in advanced HCC patients with and without hepatitis B virus or hepatitis C virus infections. Data from this study were recently published in The Lancet and will be presented at the American Society of Clinical Oncology (ASCO) Annual Meeting 2017 during a poster discussion session on June 3, 2017 from 4:45-6:00 PM CDT in Hall D2.

About Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is the most common type of liver cancer and the second most frequent cause of cancer death worldwide. More than 700,000 people around the world, including about 40,000 people in the United States, are diagnosed with HCC each year. The majority of these cases are caused by hepatitis B virus (HBV) or hepatitis C virus (HCV) infections, making HBV/HCV the most common risk factors for liver cancer.

HCC is often diagnosed in the advanced stage where treatment options are limited and outcomes are poor, with one-year survival rates in the advanced setting of

approximately 44%. For patients who are intolerant to or who have progressed during sorafenib therapy, median survival remains less than 11 months with currently available treatment options.

Bristol-Myers Squibb & Immuno-Oncology: Advancing Oncology Research

At Bristol-Myers Squibb, patients are at the center of everything we do. Our vision for the future of cancer care is focused on researching and developing transformational Immuno- Oncology (I-O) medicines for hard-to-treat cancers that could potentially improve outcomes for these patients.

We are leading the scientific understanding of I-O through our extensive portfolio of investigational compounds and approved agents. Our differentiated clinical development program is studying broad patient populations across more than 35 types of cancers with 14 clinical-stage molecules designed to target different immune system pathways. Our deep expertise and innovative clinical trial designs position us to advance I-O/I-O, I- O/chemotherapy, I-O/targeted therapies and I-O/radiation therapies across multiple tumors and potentially deliver the next wave of therapies with a sense of urgency. We also continue to pioneer research that will help facilitate a deeper understanding of the role of immune biomarkers and how patients' individual tumor biology can be used as a guide for treatment decisions throughout their journey.

We understand making the promise of I-O a reality for the many patients who may benefit from these therapies requires not only innovation on our part but also close collaboration with leading experts in the field. Our partnerships with academia, government, advocacy and biotech companies support our collective goal of providing new treatment options to advance the standards of clinical practice.

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body's own immune system to help restore anti-tumor immune response. By harnessing the body's own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo's leading global development program is based on Bristol-Myers Squibb's scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has enrolled more than 25,000 patients. The Opdivo trials have

contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 60 countries, including the United States, the European Union and Japan. In October 2015, the company's Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.
