Rhea-AI Filing Summary

The filing references the form of the note as included in Exhibit 4.1. The report is signed by Ian Estepan, President and Chief Operating Officer.

Positive

• Indenture executed with a named trustee (U.S. Bank Trust Company, National Association), providing formal legal documentation for the note
• Explicit coupon and maturity disclosed: a 4.875% coupon with a 2030 maturity is specified in the form of the note

Negative

• Potential dilution exists because the instrument is a convertible note (conversion could increase share count)
• Insufficient financial detail provided: principal amount, conversion terms, and use of proceeds are not included in the excerpt

Insights

Fixed Income / Capital Markets Analyst

TL;DR: Company documented a convertible note indenture at a fixed coupon, establishing a 2030 maturity and formal trustee arrangement.

The filing records a formal indenture dated August 28, 2025, naming U.S. Bank Trust Company, National Association as trustee and including the form of a 4.875% Convertible Senior Note due 2030 as Exhibit 4.1. From a capital-structure perspective, issuance of a convertible senior note with a fixed 4.875% coupon and a 2030 maturity creates a hybrid instrument that sits in senior debt ranking until conversion. The trustee appointment and inclusion of the note form in the filing are routine but necessary legal steps to document the terms and enable offering or issuance in accordance with securities laws. Absent additional detail on principal amount, conversion terms, or use of proceeds, material financing size and dilution impact cannot be assessed.

Corporate Governance / Securities Counsel

TL;DR: The company completed documentation for a convertible note indenture and disclosed the note form, consistent with required 8-K reporting.

The disclosure confirms execution of an indenture and that the form of the 4.875% Convertible Senior Note due 2030 is filed as an exhibit. This satisfies public disclosure requirements concerning the contractual framework and trustee appointment. Key legal elements such as trustee identity and the note form are present, but critical contractual details (principal amount, conversion price, covenants, events of default) are not included in the provided excerpt, so legal and governance implications remain limited by the available information.

Item 1.01 Entry into a Material Definitive Agreement.

As previously announced, on August 20, 2025, Sarepta Therapeutics, Inc. (the “Company”) entered into separate, privately negotiated exchange agreements (the “Exchange Agreements”) with certain holders of its 1.25% Convertible Senior Notes due 2027 (the “Existing Convertible Notes”). Under the terms of the Exchange Agreements, the holders party thereto agreed to exchange with the Company $700.0 million in aggregate principal amount of Existing Convertible Notes held by them for consideration consisting of (i) $602.0 million in aggregate principal amount of 4.875% Convertible Senior Notes due 2030 (the “New Convertible Notes”), (ii) an aggregate of 5,851,693 shares of the Company’s common stock, par value $0.0001 per share (“Common Stock”), and (iii) an aggregate of approximately $123.3 million in cash.

The New Convertible Notes were issued by the Company on August 28, 2025 pursuant to an Indenture, dated as of such date (the “Indenture”), between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”). The New Convertible Notes bear cash interest at the annual rate of 4.875%, payable on March 1 and September 1 of each year, beginning on March 1, 2026, and will mature on September 1, 2030 unless earlier redeemed, converted or repurchased. The Company will settle conversions of New Convertible Notes through payment or delivery, as the case may be, of cash, Common Stock or a combination of cash and Common Stock, at the Company’s option (subject to, and in accordance with, the settlement provisions of the Indenture). The New Convertible Notes have an initial conversion rate of 16.6667 shares of Common Stock (subject to adjustment as provided for in the Indenture) per $1,000 principal amount of New Convertible Notes (which is equivalent to an initial conversion price of approximately $60.00 per share of Common Stock), representing an approximately 191.5% conversion premium based on the last reported sale price of Common Stock of $20.58 per share on August 20, 2025.

Prior to September 6, 2028, the New Convertible Notes will not be redeemable. On or after September 6, 2028 and on or before the 21st scheduled trading day immediately preceding the maturity date, the Company may redeem for cash all or part of the New Convertible Notes (subject to certain conditions), at its option, if the last reported sale price of the Common Stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption. If the Company elects to redeem fewer than all of the outstanding New Convertible Notes, at least $150.0 million aggregate principal amount of New Convertible Notes must be outstanding and not subject to redemption as of, and after giving effect to, delivery of the relevant notice of redemption.

Holders of the New Convertible Notes may convert their New Convertible Notes at their option at any time prior to the close of business on the business day immediately preceding March 1, 2030 in multiples of $1,000 principal amount, only under the following circumstances:

• during any calendar quarter commencing after the calendar quarter ending on December 31, 2025 (and only during such calendar quarter), if the last reported sale price of the Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the New Convertible Notes on each applicable trading day;

• during the five business day period after any five consecutive trading day period (the “measurement period”) in which the “trading price” (as defined in the Indenture) per $1,000 principal amount of New Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Common Stock and the conversion rate for the New Convertible Notes on each such trading day;

• if the Company calls any or all of the New Convertible Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately prior to the redemption date, but only with respect to the New Convertible Notes called (or deemed called) for redemption; or

• upon the occurrence of specified corporate events described in the Indenture.

On or after March 1, 2030, until the close of business on the second scheduled trading day immediately preceding September 1, 2030, holders may convert their New Convertible Notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances.

If the Company experiences a fundamental change or gives a notice of redemption with respect to any or all of the New Convertible Notes, as described in the Indenture, prior to the maturity date of the New Convertible Notes, holders of the New Convertible Notes will, subject to specified conditions, have the right, at their option, to require the Company to repurchase for cash all or a portion of their New Convertible Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. In addition, following certain corporate events that occur prior to the maturity date of the New Convertible Notes, the Company will increase the conversion rate for a holder who elects to convert its New Convertible Notes in connection with such corporate event.

The Indenture provides for customary events of default. In the case of an event of default with respect to the New Convertible Notes arising from specified events of bankruptcy or insolvency, all outstanding New Convertible Notes will become due and payable immediately without further action or notice. If any other event of default with respect to the New Convertible Notes under the Indenture occurs or is continuing, the Trustee or holders of at least 25% in aggregate principal amount of the then outstanding New Convertible Notes may declare the principal amount of the New Convertible Notes to be immediately due and payable.

The foregoing description of the Indenture and the New Convertible Notes does not purport to be complete and is qualified in its entirety by reference to each of the Indenture and form of Note, which are filed as Exhibits 4.1 and 4.2 to this Current Report on Form 8-K and are incorporated herein by reference.
