Option Exchange Program: For Your Financial Well-Being

This is your opportunity to restore the potential value of your stock options and build toward lasting value. The Option Exchange is subject to shareholder approval, and if approved, will launch in mid-November. To support your decision making, we’ve launched a new resource hub at go/OptionExchange with:

October Information Sessions Meeting Invites

Subject:  Learn More About the Option Exchange Program!

Body of Invite (calendar description):
We’re excited to invite you to an Option Exchange Information Session — your chance to learn more about this unique opportunity and how it works!

During the session, we’ll:

•	Review the key design features of the program

Three sessions are available — choose the one that works best for you.

•	Session 1: Tuesday, October 21 | 8:00–9:00 p.m. EST

No RSVP required — just join the session that fits your schedule.

This communication is not an offer to exchange any options. The option exchange has not yet commenced, and there can be no assurance that it will be implemented even if it is approved by Moderna shareholders. Moderna will file a Tender Offer Statement on Schedule TO with the SEC if and when the option exchange commences. If Moderna commences the option exchange, we will provide employees who are eligible to participate in the exchange program with written materials explaining the precise terms and timing of the program. You should read these materials carefully when they become available, because they will contain important information about the option exchange. You will also be able to obtain the tender offer statement and other documents filed by Moderna with the SEC free of charge from the SEC’s website at www.sec.gov.
