Gilead + Kite: Bringing Life-Saving Therapies to Patients Kite’s platform, pipeline and scientific expertise establish Gilead’s leadership in cell therapy for oncology Builds a foundation for dramatically improving treatment of hematological malignancies and solid tumors Gilead has transformed the care of HIV and viral hepatitis, and is committed to bringing that same innovation to cancer patients Gilead has a successful track record of driving continuous innovation to improve upon existing products Diversifies Gilead’s portfolio and creates long-term shareholder value 4

Transaction Details Gilead to acquire Kite for $180 per share in cash or total purchase price of $11.9 billion Transaction is expected to be neutral to earnings by year three and accretive thereafter The acquisition represents a 29 percent premium to Kite’s closing on Friday, August 25, and a 50 percent premium to the company’s 30-day volume weighted average stock price Gilead intends to fund the acquisition with a combination of cash on hand, bank debt and senior unsecured notes Transaction unanimously approved by the Boards of Directors of both companies The acquisition is expected to close during the fourth quarter of 2017, subject to regulatory approvals and other customary closing conditions 5

Kite: An Overview 6 Kite is headquartered in Santa Monica, California and has ~650 employees, with operations in the U.S., Europe and joint venture in China (FosunKite) Axi-cel, the company’s lead product, is under review with a U.S. PDUFA date of Nov. 29, 2017 and European approval anticipated in 2018 Kite has multiple ongoing/planned clinical trials across hematological malignancies and solid tumors Clinical data show durable responses in cancer patients treated with axi-cel who have run out of options

Ready to Launch Kite has fully-integrated infrastructure to launch first-in-class, best-in-class treatment for three types of aggressive non-Hodgkin lymphoma, with other indications to follow Kite has a state-of-the-art, commercial scale cell therapy processing facility, located in El Segundo (Los Angeles) Production is efficient and can be quickly expanded to meet increased demand, as needed 7

Understanding Cell Therapy 8

Cell Therapy: An Emerging Field with the Potential to Transform Cancer Treatment 9 Cell therapy is a new way of treating cancer that uses a patient’s own immune system to fight the disease Kite’s industry-leading cell therapy pipeline is based on two different platforms: CAR (chimeric antigen receptor) T cells and TCR (T-cell receptor) engineered cells Data from CAR T trials have generated enthusiasm among oncologists as next frontier in cancer treatment

The Science of CAR T 10 CAR T T cells are taken from patients and engineered to express chimeric antigen receptors (CARs), which direct T cells to detect and destroy tumor cells Upon engagement with the specified cancer cell, the CAR T-cell “activates” resulting in the killing of the target cell CAR T-cells also undergo proliferation, which increases the number of therapeutic cells to eradicate cancer How it Works

Exciting Data Published Across Numerous Journals 11 “This clinical trial extends the reach of TCR gene therapy for patients with metastatic cancer.” “These results show that anti-CD19 CAR T-cells can cause long complete responses of chemotherapy-refractory DLBCL and that anti-CD19 CAR T cells are possibly a curative therapy for lymphoma.” Kochenderfer, James N. et al. Molecular Therapy, 13 July 2017 (online pub.) “At the first follow-up 40 days after cell therapy, we found that all seven lung metastases [in a patient with metastatic colorectal cancer] had regressed on CT. Of these lesions, six had either completely regressed or showed continuing regression 9 months after therapy.” Rosenberg, Steve A. et al N Engl J Med 2016; 375:2255-2262 8 Dec. 2016 Rosenberg, Steve A. et al Journal of Clinical Oncology - published online before print 15 August 2017

Axicabtagene Ciloleucel (axi-cel): Under priority FDA review for aggressive non-Hodgkin lymphoma which includes diffuse large B-cell lymphoma (DLBCL), transformed follicular lymphoma (TFL) and primary mediastinal B-cell lymphoma (PMBCL) Under review in Europe with approval anticipated in 2018 Axi-Cel is Nearing Approval in First Indication 12 Vein to vein time averaged 17 days in clinical trials

Lack of Therapeutic Options for People with DLBCL Diffuse large B-cell lymphoma is the most common form of non-Hodgkin lymphoma Outcomes for patients with DLBCL whose disease has relapsed or who have become refractory to existing therapies are poor (SCHOLAR-1 study): Initial complete response treated with standard of care: 7 percent Median overall survival: 6.3 months 13

Axi-Cel Pivotal Data Illustrate Promise of CAR T 14 Results from Kite’s ZUMA-1 pivotal trial in which patients with relapsed/ refractory DLBCL were treated with axi-cel: Initial complete response treated with axi-cel: 54 percent Median overall survival: Not yet reached at 8.7 months Complete Response (CR) 54%

Kite Has a Comprehensive Pipeline 15

Kite: Ongoing Launch Preparation 16

Reaching DLBCL Patients 17 Cumulative percentage of total DLBCL patients covered by transplant centers 70+ centers targeted by end of year 1, reaching ~90% of people with DLBCL 70+

A Patient-Centered Approach 18 Kite Konnect™ program will create optimal experience for patients and physicians Field teams fully staffed and trained Company has diligently worked to prepare first sites to treat patients and anticipates launching with at least 10 leading cancer centers Vein to vein time averaged 17 days in clinical trials

European Union: Preparing to Launch in 2018 Axi-cel EU submission completed in July 2017 Building infrastructure – leadership with proven oncology track record Enrolling patients in clinical sites Building network with thought leaders and clinical organizations Establishing supply chain 19

Gilead: A History of Innovation 20

Gilead Has Transformed Care for People with HIV HAART 1996 2006 B/F/TAF PDUFA 2/12/2018 6 STRs over a 12-year period 21

Gilead Has Transformed Care for People with HCV 22 4 options to cure HCV in 4 years

Together, We Will 23 Drive continuous scientific and medical innovation to improve care for people with cancer Develop next generations of novel therapies in areas of significant unmet need Design and execute clinical programs to shorten development timelines Scale complicated manufacturing processes to meet patient demand Bring innovative, new cellular therapies to patients around the world

Exhibit 99.3

Severin, Chade (BOS) From: Sent: To: Subject: Attachments: Employee Communications <EmployeeCommunications@gilead.com> Monday, August 28, 2017 9:41 AM #Operating Group; #Senior Directors Message from John Milligan: Kite Acquisition GILD Infographic.pdf; 08.28.17 Gilead Kite Press Release.pdf To Operating Group and Senior Directors, As you have seen from the attached press release, this morning we announced an agreement to acquire Kite for $11.9 billion. This is an exciting development and I’m sure you and your teams have many questions about what happens next. We have not yet finalized the operating model or future organizational structure of the combined companies. We have decided that Kite’s research and development (R&D), as well as the commercialization operations, will remain based in Santa Monica, California, with product manufacturing remaining in El Segundo, California. Because of the highly technical nature of CAR T and Kite’s science, and the interconnectivity of R&D, manufacturing and commercial operations, we will be working to determine the best management structure over the coming weeks, as we get to know the Kite team further. During this period, it is important that employees do not make any assumptions about what the structure will be, or how we will integrate Kite’s employees into our own functions. Additionally, because Kite has a November 29, 2017 FDA action date for its lead product – axi-cel – it is critical that we do not disrupt their launch preparations in any way. Some of you participated in the analysis and review of Kite leading up the acquisition. I want to thank you for all of those efforts and also remind you to keep the information you learned in that evaluation confidential. I will be assigning a senior leader within Gilead to serve as the integration lead, to ensure we coordinate all activities during the transition and after the close of the acquisition. You will hear more about this in the coming weeks. Because this is an acquisition of a public company and requires antitrust review, we are subject to special restrictions on activities. As a result, please do not reach out to Kite employees without seeking input from senior leadership or legal here at Gilead. And, for the time being, please do everything you can to keep your teams focused on Gilead’s business so that we can achieve the aggressive goals we have set for ourselves. I’ve also attached an infographic that summarizes the deal, which is also posted on GNet and Gilead.com and you can share with your teams. Thanks, John 1

Severin, Chade (BOS) From: Sent: To: Subject: Amy Flood <Amy.Flood@gilead.com> Monday, August 28, 2017 7:10 AM Marni Kottle; Nathan Kaiser FW: On Behalf of John Milligan, CEO of Gilead This has been sent From: Christine Cassiano [mailto:ccassiano@kitepharma.com] Sent: Monday, August 28, 2017 4:09 AM To: DL-Kite Pharma US employees; DL-Kite Pharma EU employees Subject: On Behalf of John Milligan, CEO of Gilead Dear Kite Employees, I’m writing to introduce myself and the Gilead team, and to share how excited we are about the prospect of our companies joining together. Gilead is a research-based biopharmaceutical company and we have worked to solve complicated scientific problems, discovering and developing medicines that have evolved and transformed care for people with HIV and, more recently, viral hepatitis. Like Kite, we have operated at the forefront of science and have a history of driving rapid innovation to bring more effective and safer products to as many people as we can, as quickly as possible. We have a deep admiration for the work you have done to overcome many significant technical hurdles to develop axi-cel and prepare for a successful commercial launch. You have built a technology platform that is poised to make a tremendous difference for people, producing many different living therapies to potentially cure advanced cancers. We believe that together we will be a remarkable combination, providing tremendous benefit to both of our teams – and to people around the world whose lives will be improved by revolutionary new treatments. We are inspired by all you have accomplished to date, as well as the opportunity ahead of us, and look forward to working with you. I will be in El Segundo this afternoon and I look forward to meeting many of you in person and sharing more about Gilead and our vision for the future. With thanks, John This e-mail contains information that may be confidential. If you are not the intended recipient, please delete the e-mail and notify the sender at Kite Pharma immediately. 1
