Exhibit 99.1
Subject: Tonight’s announcements
Dear Icosahedrons,
This evening we made an exciting announcement about a transformative step in our path to leverage our innovative VLP platform technology to make vaccines that meaningfully impact human health. We have entered into a definitive agreement for Icosavax to be acquired by AstraZeneca, which provides an important opportunity to accelerate and expand access to IVX-A12 for older adults at risk from RSV and hMPV. We believe the proposed acquisition will advance our shared mission of developing vaccines against infectious diseases. This is an incredible milestone for our company, and what we have accomplished together is a testament to the outstanding Icosavax team.
This evening we also announced positive topline interim Phase 2 results for IVX-A12. Our Phase 2 data showed robust immune response to both RSV and hMPV in older adult subjects and IVX-A12 continues to be generally well tolerated. Thank you for your hard work and dedication to reach this stage.
After careful consideration and extensive deliberation with our Board of Directors, we decided that this transaction with AstraZeneca offers important benefits for all our stakeholders and offers additional opportunities for our employees.
The acquisition allows our organizations to combine our skills and expertise with the goal of discovering and developing best-in-class vaccines to provide long-lasting immunity to millions. Icosavax will become part of AstraZeneca’s growing Vaccines & Immune Therapies business unit. We believe AstraZeneca’s resources, capabilities in late-stage development and commercialization, and therapeutic footprint will be invaluable in developing IVX-A12, as well as other pipeline vaccine candidates for those at highest risk of severe outcomes from infectious diseases. As a near-term priority of the acquisition, AstraZeneca and Icosavax together will work to progress IVX-A12 into Phase 3, with the goal of accelerating the delivery of this potential first-in-class combination VLP vaccine to patients.
The transaction is expected to close in the first quarter of 2024, subject to Icosavax shareholders tendering a sufficient number of shares, receipt of certain regulatory approvals, and satisfaction of other customary closing conditions. Until the transaction closes, Icosavax will remain an independent company and will continue to operate as such.
We are looking forward to sharing more with you at the Town Halls tomorrow starting at 10:00am PST. Please see the invites on your calendars for tomorrow and the days that follow.

We understand that you may have many questions. While we may not have all of the answers immediately, we are committed to being as transparent and timely as possible. We will send a set of FAQs to provide additional details after the Icosavax Town Hall, and we will continue to add to these FAQs as needed and as we learn more information.
Thank you, again, for your continued dedication and commitment. I look forward to speaking with you all soon.
