CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sarepta Therapeutics, Inc. (NASDAQ:SRPT), the leader in precision genetic medicine for rare diseases, today announced that it has entered into separate, privately negotiated exchange agreements with a limited number of holders of its 1.25% convertible senior notes due 2027 (the “Existing Convertible Notes”). Pursuant to the exchange agreements, the Company will exchange approximately $291.4 million in aggregate principal amount of the Existing Convertible Notes for approximately $291.4 million in aggregate principal amount of new 4.875% convertible senior notes due 2030 (the “New Convertible Notes”) and approximately $31.6 million in cash (such exchanges, collectively, the “Exchange”), in each case pursuant to exemptions from registration under the Securities Act of 1933, as amended (the “Securities Act”).

The New Convertible Notes will be issued as part of the same series as the approximately $602 million of 4.875% convertible senior notes due 2030 originally issued in August 2025, and following the closing of the Exchange, the aggregate principal amount of the Company’s 4.875% Convertible Senior Notes due 2030 will total $893.4 million. Following the closing of the Exchange, approximately $158.6 million in aggregate principal amount of the Existing Convertible Notes will remain outstanding with terms unchanged.
