Vivani Medical, Inc. Lead program NPM -119 is a miniature, 6 -month, GLP -1 implant under development for the treatment of patients with type 2 diabetes (T2D) and obesity. Vivani’s First In Human Phase 2 study of NPM-119 in T2D patients, named LIBERATE -1, was placed on Clinical Hold prior to initiating the study. A second Complete Response to the Clinical Hold was submitted on September 15, 2023. In March, we announced the proposed initial public offering of our Neuromodulation Division, renamed Cortigent, Inc. This allows Vivani to focus on our drug implant business. An innovative, biopharmaceutical company developing a portfolio of miniature, long -term, drug implants to treat chronic disease. Our NanoPortal ™ platform technology enables the design of implants aimed at improving medication non -adherence and tolerability. Vivani is well -positioned with new leadership and sufficient capital to support multiple milestones for NPM -119 and our emerging pipeline of innovative therapeutic implants. 4

The requested information was related to the assessment of device risks and device performance. September 15, 2023 –Vivani provided a second Complete Response (CR) including additional information and commitments to obtain supplemental information in parallel with the conduct of LIBERATE-1. Per guidelines, FDA has 30 days after the submission date to respond. • If the CR is adequate and the Clinical Hold is lifted, Vivani anticipates commencing LIBERATE-1 in 2023, preliminary results in 1Q2024, interim results in 1H2024, and top-line results 2H2024. • If the CR is deemed inadequate, Vivani will provide updated guidance as appropriate. 20
