Our Path Forward We believe FX-322 restores hearing. We know characteristics of FX-322 responders. Learnings from previous trials informed new trial design with strong controls and FDA aligned clinical endpoints. We have a compelling new hearing program that will allow us to explore the impact of going deeper into the cochlea. We also have an exciting remyelination program in multiple sclerosis with a novel target and a strong response in vivo. We are a well capitalized company with resources to deliver innovation for patients and value for investors. • $142.4m in cash and cash equivalents*, runway through the end of 2023 • Ex-US partnership with Astellas, significant milestones and royalties *Number reflects unaudited Cash, Cash Equivalents, and Marketable Securities as of December 31, 2021, and does not include Restricted Cash © Frequency Therapeutics, Inc. | 40
