Nature of Operations	1. Nature of Operations Organization Intellia Therapeutics, Inc. (“Intellia” or the “Company”) is a leading clinical-stage gene editing company focused on revolutionizing medicine with CRISPR-based therapies. CRISPR is a gene editing technology which is also sometimes referred to as CRISPR/Cas or CRISPR/Cas9 when referring to the use of CRISPR technology with the Cas9 enzyme. Since its inception, Intellia has focused on leveraging gene editing technology to develop novel, first-in-class medicines that address important unmet medical needs and advance the treatment paradigm for patients. Intellia’s deep scientific, technical and clinical development experience, along with its people, is helping set the standard for a new class of medicine. To harness the full potential of gene editing, Intellia continues to expand the capabilities of its CRISPR-based platform with novel editing and delivery technologies. To fully realize the transformative potential of CRISPR-based technologies, the Company is building a full-spectrum gene editing company, by leveraging its modular platform, to advance in vivo and ex vivo therapies for diseases with high unmet need by pursuing two primary approaches. For in vivo applications to address genetic diseases, the Company deploys CRISPR as the therapy. The Company’s in vivo programs use CRISPR to enable precise editing of disease-causing genes directly inside the human body. In addition, the Company is advancing ex vivo applications to address immuno-oncology and autoimmune diseases, where it uses CRISPR as the tool to create the engineered cell therapy. For its ex vivo programs, CRISPR is used to engineer human cells outside the body. The Company’s deep scientific, technical and clinical development experience, along with its robust intellectual property (“IP”) portfolio, have enabled it to unlock broad therapeutic applications of CRISPR and related technologies to create new classes of genetic medicine.

Programs currently in development or moving into development will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval prior to commercialization.
